[0070] Next, the related technologies involved in the embodiments of the application are introduced:

[0071] · Physical downlink control channel detection

[0072] The network device sends DCI to the terminal device, the DCI is used for downlink scheduling, for example, scheduling a physical downlink shared channel (PDSCH), or the DCI is used for uplink authorization, for example, scheduling a physical uplink shared channel (PUSCH), or the DCI is used for transmitting common control information, and the DCI is carried through a PDCCH. The network device configures a search space for the terminal device, and the network device can configure different aggregation levels (ALs), and under each aggregation level, the number of candidate PDCCHs that the terminal device needs to monitor is configured. The terminal device needs to perform PDCCH detection in the search space, and the maximum number of PDCCHs that the terminal device needs to monitor in a slot is related to the subcarrier spacing, for example, when the subcarrier spacing is 15 kHz, the maximum number of PDCCHs that the terminal device needs to monitor in a slot is 44. Referring to Table 1, when the subcarrier spacing parameter μ takes values of 0, 1, 2, and 3, the subcarrier spacing corresponds to 15 kHz, 30 kHz, 60 kHz, and 120 kHz, respectively.

[0073] Table 1

[0074] In the 5G NR system, DCI adopts Polar coding, and the terminal needs to perform decoding processing every time it detects PDCCH, which can cause high power consumption and increase processing delay.

[0075] The transmission resource of one PDCCH can include M1 control channel elements (CCEs), that is, corresponding to different aggregation levels AL, for example, M1 = 1, 2, 4, 8, 16, and the relationship between the aggregation level and the number of CCEs is shown in Table 2; each CCE can include M2 resource element groups (REGs), for example, M2 = 6, one REG corresponds to one physical resource block (PRB) in the frequency domain and one orthogonal frequency division multiplexing (OFDM) symbol in the time domain; the number of CCEs occupied by the PDCCH is different, and its transmission reliability is also different, for example, the more CCEs occupied by the PDCCH, the higher its transmission reliability.

[0076] Table 2

[0077] ·Terminal device complexity optimization:

[0078] The terminal device can be referred to as a terminal, and the terminal in the related art is designed to support a very high peak rate. Therefore, the terminal has a high capability requirement. The LTE standard defines that the maximum single carrier bandwidth is 20MHz, and a larger bandwidth is implemented by multi-carrier aggregation. The maximum carrier bandwidth of 5G NR is finally defined as 100MHz in the low frequency band below 6GHz, which is 5 times of LTE, and the maximum carrier bandwidth of the millimeter wave frequency band is 400MHz. The Multiple-Input Multiple-Output (MIMO) antenna scale required by NR is further improved. The terminal antenna reference configuration of LTE is one transmission and two receptions, and the NR R15 requires two transmissions and four receptions at a frequency point above 2500MHz.

[0079] However, some application scenarios of NR do not require such high processing capability in terms of processing capacity and speed, including Internet of Things, industrial automation and wearable device applications. In these scenarios, the communication hardware is required to have a lower volume and power consumption, and the light weight capability requirement is a feature of such terminals. Based on such considerations, the NR R17 research introduces the standard of a compact terminal with reduce capability (RedCap).

[0080] The compact terminal standard reduces some mandatory capabilities of NR R15 / R16. The corresponding terminal function groups are defined for these capabilities. The compact terminal standard further optimizes the power consumption of terminal identification, access process and optimized measurement to adapt to the related application scenarios. The design of such a compact terminal can significantly reduce the complexity of the terminal hardware. At the same time, it can also correspondingly reduce the energy consumption of the terminal and achieve the effect of energy saving.

[0081] Before introducing the technical solutions of the present application, some contents related to the present application will be introduced and explained. The following contents can be combined with the technical solutions of the embodiments of the present application as optional solutions, which all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0082] In some embodiments, the network device configures a group of transmission resources for the terminal device, and the group of transmission resources includes at least two transmission resources.

[0083] Optionally, the set of transmission resources includes the first transmission resource and other transmission resources, the other transmission resources being transmission resources in the set of transmission resources other than the first transmission resource. For example, the other transmission resources include a second transmission resource. The first transmission resource is used to transmit the first indication information, and the second transmission resource is used for downlink transmission. The transmission content of the downlink transmission (i.e., downlink transmission content) includes downlink data and / or downlink control information (DCI). The embodiments below are mainly exemplified with the other transmission resources including the second transmission resource, but are not limited thereto, for example, the other transmission resources can also include a third transmission resource used for uplink transmission.

[0084] In the embodiments of the present application, the network device configures the terminal device with the first transmission resource and the second transmission resource, and there is an association relationship between the first transmission resource and the second transmission resource. The terminal device can determine the position of the second transmission resource based on the position of the first transmission resource.

[0085] Correspondence between the first transmission resource and the second transmission resource

[0086] In some embodiments, the correspondence can also be referred to as an association relationship.

[0087] In some embodiments, the correspondence between the first transmission resource and the second transmission resource is one-to-one, or many-to-one, or one-to-many; where one-to-one means that one first transmission resource corresponds to one second transmission resource, many-to-one means that multiple first transmission resources correspond to the same second transmission resource, and one-to-many means that one first transmission resource corresponds to multiple second transmission resources.

[0088] Optionally, when the correspondence between the first transmission resource and the second transmission resource is many-to-one, the multiple first transmission resources correspond to different at least one of time domain resources, frequency domain resources, or code domain resources. For example, the multiple first transmission resources have the same time domain resources and different frequency domain resources; or the multiple first transmission resources have different time domain resources and the same frequency domain resources; or the multiple first transmission resources have the same time domain resources and the same frequency domain resources, and different code domain resources. For example, the multiple first transmission resources are located in the same time domain symbol, but correspond to different PRBs; for another example, the multiple first transmission resources are located in different time domain symbols, and have the same frequency domain resources; for another example, the multiple first transmission resources are located in the same time domain symbol, have the same frequency domain resources, but correspond to different sequences.

[0089] Optionally, when the correspondence between the first transmission resource and the second transmission resource is one-to-many, the multiple second transmission resources have the same time domain resource and different frequency domain resources; or, the multiple second transmission resources have different time domain resources and the same frequency domain resource. For example, the multiple second transmission resources are located in the same time domain symbol but have different corresponding PRBs; for another example, the multiple second transmission resources have different time domain resources and the same frequency domain resource.

[0090] FIG. 2 shows a schematic diagram of the correspondence between the transmission resources according to an example embodiment of the present application.

[0091] In (a) of FIG. 2, the correspondence between the first transmission resource and the second transmission resource is one-to-one, i.e., one first transmission resource corresponds to one second transmission resource; in (b) of FIG. 2, the correspondence between the first transmission resource and the second transmission resource is many-to-one, i.e., two first transmission resources correspond to the same second transmission resource; in (c) of FIG. 2, the correspondence between the first transmission resource and the second transmission resource is one-to-many, i.e., one first transmission resource corresponds to two second transmission resources.

[0092] Position relationship between the first transmission resource and the second transmission resource

[0093] In some embodiments, the position of the second transmission resource is determined based on the position of the first transmission resource; or, there is a predefined relationship between the position of the second transmission resource and the position of the first transmission resource based on the communication protocol; or, there is a preconfigured relationship between the position of the second transmission resource and the position of the first transmission resource based on the network.

[0094] By way of example and not limitation, the position relationship between the first transmission resource and the second transmission resource includes at least one of the following:

[0095] The time domain of the first transmission resource is not adjacent to the time domain of the second transmission resource; the time domain of the first transmission resource is adjacent to the time domain of the second transmission resource; the time domain start position of the first transmission resource is the same as the time domain start position of the second transmission resource; the frequency domain start position of the first transmission resource is the same as the frequency domain start position of the second transmission resource; the frequency domain center position of the first transmission resource is the same as the frequency domain center position of the second transmission resource; the frequency domain end position of the first transmission resource is the same as the frequency domain end position of the second transmission resource.

[0096] The time domain of the first transmission resource is adjacent to the time domain of the second transmission resource means that the time domain end position of the first transmission resource is adjacent to the time domain start position of the second transmission resource.

[0097] FIG. 3 shows a schematic diagram of the position relationship between the transmission resources according to an example embodiment of the present application.

[0098] In the (a) part of FIG. 3, the time domain of the first transmission resource and the second transmission resource is not adjacent, and the frequency domain center position of the first transmission resource is the same as the frequency domain center position of the second transmission resource.

[0099] In the (b) part of FIG. 3, the time domain of the first transmission resource and the second transmission resource is adjacent, and the frequency domain center position of the first transmission resource is the same as the frequency domain center position of the second transmission resource.

[0100] In the (c) part of FIG. 3, the time domain start position of the first transmission resource is the same as the time domain start position of the second transmission resource, and the frequency domain start position of the first transmission resource is the same as the frequency domain start position of the second transmission resource.

[0101] In the (d) part of FIG. 3, the time domain start position of the first transmission resource is the same as the time domain start position of the second transmission resource, and the frequency domain center position of the first transmission resource is the same as the frequency domain center position of the second transmission resource.

[0102] In the (e) part of FIG. 3, the time domain start position of the first transmission resource is the same as the time domain start position of the second transmission resource, and the frequency domain end position of the first transmission resource is the same as the frequency domain end position of the second transmission resource.

[0103] The type of the first transmission resource and the second transmission resource

[0104] In some embodiments, the first transmission resource and the second transmission resource are common transmission resources shared by a plurality of terminal devices, or the first transmission resource and the second transmission resource are group transmission resources shared by a terminal device group, or the first transmission resource and the second transmission resource are dedicated transmission resources used by a terminal device.

[0105] In some embodiments, when the first transmission resource and the second transmission resource are common transmission resources shared by a plurality of terminal devices or group transmission resources shared by a terminal device group, the second transmission resource is used to transmit common DCI and / or common downlink data, and the common DCI and / or common downlink data are used to transmit at least one of the following information: broadcast information, system information, paging information, random access response information.

[0106] In some embodiments, the network device configures the same first transmission resource and the same second transmission resource for a plurality of terminal devices, that is, the first transmission resource and the second transmission resource are common transmission resources shared by a plurality of terminal devices; the network device configures the same sequence for a plurality of terminal devices, or the network device respectively configures a corresponding sequence for each terminal device, and the terminal device detects the first indication information on the first transmission resource based on the configured sequence.

[0107] For example, the network device configures terminal device 1 with sequence 1 and configures terminal device 2 with sequence 1, and both terminal device 1 and terminal device 2 detect the first indication information on the first transmission resource based on sequence 1.

[0108] For example, the network device configures terminal device 1 with sequence 1 and configures terminal device 2 with sequence 2, and terminal device 1 detects the first indication information on the first transmission resource based on sequence 1, and terminal device 2 detects the first indication information on the first transmission resource based on sequence 2.

[0109] The network device configures the first transmission resource and the second transmission resource for transmission of the common DCI and / or the common downlink data, transmits the first indication information on the first transmission resource, and the sequence corresponding to the first indication information is a common sequence, and transmits the common DCI and / or the common downlink data on the second transmission resource.

[0110] In some embodiments, a plurality of terminal devices detect whether there is first indication information on the first transmission resource based on a same common sequence.

[0111] For example, the network device configures terminal device 1 and terminal device 2 with a common sequence 1, and terminal device 1 and terminal device 2 detect the first indication information on the first transmission resource based on the common sequence 1.

[0112] If the terminal device detects the first indication information, the terminal device detects the common DCI and / or the common downlink data on the second transmission resource based on the first indication information, and the common DCI and the common downlink data are used to transmit at least one of the following information: broadcast information, system information, paging information, and random access response information.

[0113] For example, the broadcast information is Master Information Block (MIB) information, the system information is System Information Block (SIB) information, the paging information is Paging information, and the random access response information is Random Access Response (RAR) information.

[0114] In some embodiments, the network device configures a common transmission resource including a common first transmission resource and a common second transmission resource for transmission of the common DCI and the common downlink data.

[0115] The common first transmission resource and the common second transmission resource can also be referred to as a cell-specific first transmission resource and a cell-specific second transmission resource, or a common first transmission resource and a common second transmission resource.

[0116] Optionally, the network device configures different groups of transmission resources. It should be noted that the "group" in the group transmission resource refers to a terminal group, not the group in the above group of transmission resources.

[0117] In some embodiments, in the first configuration mode, the network device configures a group transmission resource shared by a group of terminal devices, including a group first transmission resource and a group second transmission resource, and the group second transmission resource is used for transmitting group common DCI or group common downlink data. Optionally, the group of terminal devices includes all terminal devices in a cell, and the group first transmission resource and the group second transmission resource can also be referred to as shared first transmission resource and shared second transmission resource. For example, the common DCI and the common downlink data are used for transmitting at least one of the following: slot format information, channel occupation time duration information, available resource block set information, search space set group switching information, pre-emption indication information, transmission power control (TPC), UL transmission cancellation indication, wake-up indication.

[0118] In some embodiments, in the second configuration mode, the network device configures a group transmission resource shared by a group of terminal devices, including a group second transmission resource. The network device configures different first transmission resources for the group of terminal devices. For example, the network device configures the same second transmission resource for the group of terminal devices, but configures different first transmission resources, and for each terminal device, there is an association between the configured first transmission resource and the second transmission resource; this configuration mode can realize multiple terminal devices multiplexing or sharing the second transmission resource.

[0119] For example, FIG. 4 shows a schematic diagram of configuring transmission resources provided by an example embodiment of the present application.

[0120] The (a) part of FIG. 4 corresponds to the first configuration manner described above, that is, the network device configures the same first transmission resource and the same second transmission resource for UE1 and UE2, and UE1 and UE2 share the first transmission resource and the second transmission resource. In some embodiments, the network device only sends the first indication information of UE1, which is used to indicate the transmission content on the second transmission resource, and UE1 determines whether to perform detection on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) according to the first indication information detected on the first transmission resource. In some embodiments, the network device only sends the first indication information of UE2, which is used to indicate the transmission content on the second transmission resource, and UE2 determines whether to perform detection on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) according to the first indication information detected on the first transmission resource.

[0121] The (b) part of FIG. 4 corresponds to the second configuration manner described above, that is, the network device configures the same second transmission resource for UE1 and UE2, and configures different first transmission resources for UE1 and UE2, and UE1 and UE2 share the second transmission resource. In some embodiments, the network device only sends the first indication information of UE1, which is used to indicate the transmission content of UE1 on the second transmission resource, does not send the first indication information of UE2, or sends the first indication information of UE2 to indicate no transmission on the second transmission resource. UE1 determines whether to perform detection on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) according to the first indication information detected on the first transmission resource, and UE2 determines not to perform detection on the second transmission resource according to the first indication information detected on the first transmission resource. In some embodiments, the network device only sends the first indication information of UE2, which is used to indicate the transmission content of UE2 on the second transmission resource, does not send the first indication information of UE1, or sends the first indication information of UE1 to indicate no transmission on the second transmission resource. UE2 determines whether to perform detection on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) according to the first indication information detected on the first transmission resource, and UE1 determines not to perform detection on the second transmission resource according to the first indication information detected on the first transmission resource.

[0122] Part (c) of FIG. 4 corresponds to the second configuration mode described above, and the configuration mode of part (c) of FIG. 4 is the same as that of part (b) of FIG. 4, that is, the network device configures the same second transmission resource for UE1 and UE2, the network device configures different first transmission resources for UE1 and UE2, and UE1 and UE2 share the second transmission resource. In part (c) of FIG. 4, the network device transmits the first indication information of UE1 or the first indication information of UE2, indicating the value of the transmission parameter corresponding to the transmission content on the second transmission resource. For example, the first indication information transmitted on the first transmission resource of UE1 indicates that the transmission resource of the DCI of UE1 only occupies half of the second transmission resource; the first indication information transmitted on the first transmission resource of UE2 indicates that the transmission resource of the DCI of UE2 also only occupies half of the second transmission resource, and the resources occupied by UE1 and UE2 on the second transmission resource are different, so that the two UEs can simultaneously multiplex the second transmission resource for transmission.

[0123] In some embodiments, the network device configures a user-specific (UE-specific) dedicated first transmission resource and a dedicated second transmission resource for each terminal device, respectively, wherein the dedicated first transmission resource is used to transmit first indication information specific to each terminal device, and the dedicated second transmission resource is used to transmit a DCI or downlink data specific to each terminal device.

[0124] In some embodiments, the dedicated first transmission resources of different terminal devices are non-overlapping, completely overlapping or partially overlapping, and the dedicated second transmission resources of different terminal devices are non-overlapping, completely overlapping or partially overlapping.

[0125] For example, FIG. 5 shows a schematic diagram of configuring transmission resources according to an example embodiment of the present application. The network device configures common transmission resources, group transmission resources and dedicated transmission resources. The common transmission resources include two groups of common first transmission resources and common second transmission resources. The group transmission resources include two groups of group first transmission resources and group second transmission resources. The dedicated transmission resources include eight groups of dedicated first transmission resources and dedicated second transmission resources. For the dedicated transmission resources, the network device can configure one or more dedicated first transmission resources and dedicated second transmission resources for each terminal device. Assuming that the network device configures one group of common first transmission resources and common second transmission resources, one group of group first transmission resources and group second transmission resources, and two groups of dedicated first transmission resources and dedicated second transmission resources for a terminal device, the terminal device needs to perform detection (for example, detecting whether there is first indication information in the first transmission resources) in the four groups of transmission resources, and then detect the DCI and / or downlink data in the corresponding second transmission resources. By dividing a group of transmission resources into different types of transmission resources, the range of detection of the terminal device is reduced and the detection efficiency is improved when the network device configures at least one of the common transmission resources, the group transmission resources and the dedicated transmission resources.

[0126] Indication manner of the first indication information

[0127] FIG. 6 shows a schematic diagram of an indication manner of the first indication information according to an example embodiment of the present application. The first indication information is used to indicate at least one of the following:

[0128] Manner 1: indicating that the second transmission resources are not transmitted.

[0129] In the case that the first indication information indicates that there is no transmission on the second transmission resources, the terminal device does not need to perform detection on the second transmission resources;

[0130] Optionally, a first value, a first state or a first sequence is determined based on the first indication information, and it is determined that there is no transmission on the second transmission resources based on the first value, the first state or the first sequence.

[0131] The first value is a one-bit value or a group of bit values, such as a value of 1 or 0. The first state is an on state (on) or an off state (off), which can be represented by the level or energy, or can be represented by the bit value. The first sequence is a sequence used to represent the first indication information, for example, a ZC sequence. The principles of representing the second value, the second state, the second sequence, the third value, the third state, the third sequence and other values, states and sequences are the same, and will not be described again.

[0132] In some implementations, if the terminal does not detect the first indication information on the first transmission resource, it can be determined that there is no transmission on the second transmission resource. That is, no transmission on the second transmission resource is determined by not detecting the first indication information on the first transmission resource.

[0133] Method 2: Indicate that the DCI or PDCCH is transmitted on the second transmission resource.

[0134] In some embodiments, based on the first indication information, the DCI or PDCCH is received on the second transmission resource.

[0135] In the case where the first indication information indicates that the DCI or PDCCH is transmitted on the second transmission resource, the terminal device detects the DCI or PDCCH on the second transmission resource. For example, a search space is configured on the second transmission resource, and the terminal device detects the DCI or PDCCH on the search space. In some embodiments, the detection complexity of the search space is low, such as only one aggregation level is configured in the search space, and the number of candidate PDCCHs configured under the aggregation level is 2, that is, the terminal device only needs to perform PDCCH detection at most 2 times in the search space.

[0136] Optionally, based on the first indication information, a second value, a second state or a second sequence is determined, and based on the second value, the second state or the second sequence, it is determined that the DCI or PDCCH is transmitted on the second transmission resource.

[0137] Method 3: Indicate that the first downlink data is transmitted on the second transmission resource.

[0138] In some embodiments, the terminal device receives the first downlink data on the second transmission resource based on the first indication information. Optionally, in the case where the second transmission resource is not indicated to transmit the first downlink data, it is not necessary to detect the first downlink data on the second transmission resource.

[0139] In the case where the first indication information indicates that the first downlink data is transmitted on the second transmission resource, the terminal device detects the first downlink data on the second transmission resource. Optionally, the first downlink data is carried by PDSCH;

[0140] Optionally, based on the first indication information, a third value, a third state or a third sequence is determined, and based on the third value, the third state or the third sequence, it is determined that the first downlink data is transmitted on the second transmission resource.

[0141] Method 4: Indicate that the DCI and the first downlink data are transmitted on the second transmission resource.

[0142] In some embodiments, based on the first indication information, the DCI and the first downlink data are simultaneously received on the second transmission resource, or, based on the first indication information, the downlink control channel and the first downlink data are simultaneously received on the second transmission resource.

[0143] By way of example and not limitation, the DCI is used to schedule the second downlink data, or, the DCI is used to schedule the second uplink data.

[0144] In some embodiments, the DCI used to schedule the second downlink data includes: the DCI used to indicate the transmission resource of the second downlink data, and / or, the DCI used to indicate the transmission parameter of the second downlink data; the DCI used to schedule the second uplink data includes: the DCI used to indicate the transmission resource of the second uplink data, and / or, the DCI used to indicate the transmission parameter of the second uplink data.

[0145] Characteristics of the first indication information

[0146] In some embodiments, the first indication information is indicated in a sequence manner, or is understood as being carried by a sequence, and the sequence type used to carry the first indication information includes at least one of a complex (vector) sequence and a real sequence. The complex (vector) sequence includes at least one of: a constant amplitude zero auto-correlation (CAZAC) sequence; a ZC (Zaddoff Chu) sequence. The real sequence includes at least one of: a pseudo-random sequence; a Gold sequence; an m-sequence; a Hadamard sequence. Alternatively, the sequence used to carry the first indication information is generated or determined based on the above sequence types.

[0147] Sending the first indication information in a sequence manner can enable the terminal device to determine the information indicated by the first indication information based on sequence detection (such as sequence correlation detection), avoid decoding processing, and reduce power consumption and processing delay of the terminal device.

[0148] In some embodiments, the first indication information is carried by a first sequence, and the length of the first sequence is determined based on at least one of the following: protocol pre-defined information; configuration information sent by the network; the size of the frequency domain resource included in the first transmission resource.

[0149] For example, the first transmission resource includes K subcarriers or resource elements (REs), and the sequence length L is the largest prime number less than or equal to K, or the largest prime number less than or equal to (K / A), where A is a predetermined positive integer, for example, A = 2 or 4.

[0150] For example, the sequence length L is a largest prime number less than or equal to K, K = 60, L = 59; or K = 72, L = 71; or K = 120, L = 113.

[0151] In some embodiments, the first indication information is carried by the first bit or at least one bit, including the first bit or at least one bit being processed by channel coding, modulation, etc. to generate a data packet or a transport block.

[0152] The first indication information is carried by a sequence or at least one bit

[0153] In some embodiments, the first indication information is carried by a sequence or at least one bit, and the present application mainly describes the case that the first indication information is carried by a sequence. Alternatively, the sequence index of the sequence is associated with the transmission content. The at least one bit can also be referred to as at least one information bit, or referred to as a bit sequence. Alternatively, the correspondence between the sequence index and the transmission content is determined by protocol predefined information or network configuration information.

[0154] For example, the first indication information is carried by 4 sequences, and the correspondence between the sequence index and the transmission content is shown in Table 3.

[0155] Table 3

[0156] For example, when the sequence index is 0, the corresponding transmission content is "no transmission on the second transmission resource"; when the sequence index is 1, the corresponding transmission content is "transmission of the second DCI on the second transmission resource"; when the sequence index is 2, the corresponding transmission content is "transmission of the first downlink data on the second transmission resource"; and when the sequence index is 3, the corresponding transmission content is "transmission of the first downlink data and the second DCI on the second transmission resource". The sequence index is expressed in decimal, and in actual implementation, it can be expressed in binary, which is not limited in the present embodiment.

[0157] It should be noted that the above Table 3 is only an exemplary description of the correspondence between the sequence index and the transmission content, and the method in the present embodiment is not limited to the correspondence in Table 3. In some embodiments, the network configured correspondence only includes part of the contents in the above table, such as only including any 2 rows in the above table; in some embodiments, the sequence index included in the network configured correspondence is K, and the corresponding transmission content is also K, where K is an integer greater than or equal to 1.

[0158] The first indication information is used to indicate the first value

[0159] In some embodiments, the first indication information is used to indicate the first value, and the first value is associated with the transmission content.

[0160] Optionally, the correspondence between the first value and the transmission content is determined by protocol predefined information or network configuration information.

[0161] For example, the first indication information is used to indicate 4 values of the first value, and the correspondence between the first value and the transmission content is shown in Table 4:

[0162] Table 4

[0163] For example, when the first value is 0, the corresponding transmission content is "no transmission on the second transmission resource"; when the first value is 1, the corresponding transmission content is "transmission of the second DCI on the second transmission resource"; when the first value is 2, the corresponding transmission content is "transmission of the first downlink data on the second transmission resource"; and when the first value is 3, the corresponding transmission content is "transmission of the first downlink data and the second DCI on the second transmission resource". The first value is expressed in decimal, and in actual implementation, it can be expressed in binary, which is not limited in the embodiment.

[0164] It should be noted that the above Table 4 is only an exemplary description of the correspondence between the first value and the transmission content, and the method in the embodiment of the application is not limited to the correspondence in Table 4. In some embodiments, the network configured correspondence only includes part of the content in the above table, such as only including any 2 rows in the above table; in some embodiments, the first value included in the network configured correspondence is K, and the corresponding transmission content is also K, where K is an integer greater than or equal to 1.

[0165] determining the transmission content on the second transmission resource based on the first indication information and / or the second information associated with the first indication information

[0166] In some embodiments, the transmission content on the second transmission resource is determined based on the first indication information; or the transmission content on the second transmission resource is determined based on the second information associated with the first indication information; or the transmission content on the second transmission resource is determined based on the combination of the first indication information and the second information associated with the first indication information.

[0167] In some embodiments, the first indication information is carried by a first sequence or at least one bit. Determining the transmission content on the second transmission resource based on the first indication information can also be understood as determining the transmission content on the second transmission resource based on the sequence or at least one bit carrying the first indication information. Optionally, different sequences or different at least one bit indicate different transmission contents on the second transmission resource.

[0168] In some embodiments, the second information comprises at least one of: a frequency domain resource corresponding to the first indication information, a time domain resource corresponding to the first indication information, a first parameter corresponding to a first sequence carrying the first indication information. Optionally, the first parameter comprises at least one of: an initial value corresponding to the first sequence, a cyclic shift value corresponding to the first sequence, a group number corresponding to the first sequence, an intra-group root sequence number corresponding to the first sequence, a sequence length corresponding to the first sequence, a sequence index corresponding to the first sequence. The first sequence is used to carry the first indication information.

[0169] For example, different lengths of the first sequence correspond to different values or different states or different sequences or different indexes, thereby indicating different transmission contents on the second transmission resource.

[0170] For example, different frequency domain resources corresponding to the first indication information correspond to different values or different states or different sequences or different indexes, thereby indicating different transmission contents on the second transmission resource, wherein the sequence is used to carry the first indication information.

[0171] For example, different time domain resources corresponding to the first indication information correspond to different values or different states or different sequences or different indexes, thereby indicating different transmission contents on the second transmission resource, wherein the sequence is used to carry the first indication information.

[0172] For example, different sequence groups corresponding to the first sequence correspond to different values or different states or different sequences or different indexes, thereby indicating different transmission contents on the second transmission resource.

[0173] In some embodiments, the transmission content on the second transmission resource is determined based on different second information associated with the first indication information. It can be understood that the transmission content on the second transmission resource is indicated based on different second information associated with the first indication information.

[0174] In some embodiments, the transmission content on the second transmission resource is determined based on different values of the second information associated with the first indication information. It can be understood that the transmission content on the second transmission resource is indicated based on different values of the second information associated with the first indication information.

[0175] For example, the first indication information is used to indicate the transmission content on the second transmission resource, and the first indication information is carried by a first sequence or at least one bit, and different values of the first sequence or at least one bit are used to indicate the transmission content on the second transmission resource.

[0176] Taking an example of indicating the transmission content on the second transmission resource by using the second information, at least five different indication manners can be used to indicate the transmission content on the second transmission resource, wherein the first sequence is used to carry the first indication information.

[0177] Indication manner A: indicating the transmission content on the second transmission resource based on the length corresponding to the first sequence;

[0178] Indication manner B: indicating the transmission content on the second transmission resource based on the frequency domain resource corresponding to the first indication information;

[0179] Indication manner C: indicating the transmission content on the second transmission resource based on the time domain resource corresponding to the first indication information;

[0180] Indication manner D: indicating the transmission content on the second transmission resource based on the sequence index corresponding to the first sequence;

[0181] Indication manner E: indicating the transmission content on the second transmission resource based on the sequence group index corresponding to the first sequence.

[0182] In some embodiments, the transmission content on the second transmission resource includes at least one of the following:

[0183] no transmission on the second transmission resource, transmitting DCI or PDCCH on the second transmission resource, transmitting first downlink data on the second transmission resource, and transmitting DCI and first downlink data on the second transmission resource.

[0184] For indication manner A: indicating the transmission content on the second transmission resource based on the length corresponding to the first sequence;

[0185] There is an association relationship or a corresponding relationship between the sequence length and the transmission content, and the association relationship or the corresponding relationship is determined based on protocol predefined information or network configuration information.

[0186] For example, based on the length corresponding to the first sequence to indicate one transmission content on the second transmission resource, the length index value 1 indicates no transmission on the second transmission resource, the length index value 2 indicates transmitting DCI or PDCCH on the second transmission resource, the length index value 3 indicates transmitting first downlink data on the second transmission resource, and the like, which is not limited in the present application.

[0187] For indication manner B: indicating the transmission content on the second transmission resource based on the frequency domain resource corresponding to the first indication information;

[0188] There is an association relationship or a corresponding relationship between the frequency domain resource corresponding to the first indication information and the transmission content, and the association relationship or the corresponding relationship is determined based on protocol predefined information or network configuration information.

[0189] The frequency domain resource corresponding to the first indication information can be understood as a frequency domain resource corresponding to a first transmission resource where the first indication information is located; or, a frequency domain resource corresponding to the first indication information in the first transmission resource; or, a frequency domain resource carrying the first indication information in the first transmission resource.

[0190] For example, based on the frequency domain resource corresponding to the first indication information indicating a transmission content on the second transmission resource, a frequency domain resource index value 1 indicates no transmission on the second transmission resource, a frequency domain resource index value 2 indicates transmission of DCI or PDCCH on the second transmission resource, and a frequency domain resource index value 3 indicates transmission of first downlink data on the second transmission resource, which is not limited in the present application.

[0191] For indication mode C: based on the time domain resource corresponding to the first indication information indicating a transmission content on the second transmission resource;

[0192] The time domain resource corresponding to the first indication information and the transmission content have an association relationship or a corresponding relationship, which is determined based on protocol pre-defined information or network configuration information.

[0193] The time domain resource corresponding to the first indication information can be understood as a time domain resource corresponding to a first transmission resource where the first indication information is located; or, a time domain resource corresponding to the first indication information in the first transmission resource; or, a time domain resource carrying the first indication information in the first transmission resource.

[0194] For example, based on the time domain resource corresponding to the first indication information indicating a transmission content on the second transmission resource, a time domain resource index value 1 indicates no transmission on the second transmission resource, a time domain resource index value 2 indicates transmission of DCI or PDCCH on the second transmission resource, and a time domain resource index value 3 indicates transmission of first downlink data on the second transmission resource, which is not limited in the present application.

[0195] For indication mode D: based on the sequence index corresponding to the first sequence indicating a transmission content on the second transmission resource;

[0196] The sequence index corresponding to the sequence and the transmission content have an association relationship or a corresponding relationship, which is determined based on protocol pre-defined information or network configuration information.

[0197] For example, based on the sequence index corresponding to the first sequence indicating a transmission content on the second transmission resource, a sequence index 1 indicates no transmission on the second transmission resource, a sequence index 2 indicates transmission of DCI or PDCCH on the second transmission resource, and a sequence index 3 indicates transmission of first downlink data on the second transmission resource, which is not limited in the present application.

[0198] For the indication mode E, the second transmission resource is indicated based on the sequence group index corresponding to the first sequence.

[0199] The sequence group index corresponding to the sequence and the transmission content have a correlation or a corresponding relationship, which is determined based on protocol predefined information or network configuration information.

[0200] For example, one transmission content on the second transmission resource is indicated based on the sequence group index corresponding to the first sequence, the sequence group index 1 indicates no transmission on the second transmission resource, the sequence group index 2 indicates transmission of DCI or PDCCH on the second transmission resource, and the sequence group index 3 indicates transmission of the first downlink data on the second transmission resource. The present application does not limit this.

[0201] The first indication information is carried in the form of a sequence, so that the terminal device can determine the content indicated by the first indication information based on sequence detection, and can determine the transmission behavior on the subsequent second transmission resource based on sequence detection, and avoid decoding processing, thereby reducing the power consumption and processing delay of the terminal device.

[0202] The second transmission resource

[0203] In some embodiments, the second transmission resource is used to transmit DCI or downlink data, and the terminal device determines whether to detect on the second transmission resource based on the first indication information, or determines to detect DCI or downlink data on the second transmission resource based on the first indication information.

[0204] 1) The second transmission resource is used to transmit DCI

[0205] The first transmission resource transmits the first indication information, which indicates transmission of DCI on the second transmission resource. Optionally, the DCI is used to schedule transmission of uplink data (such as PUSCH), or is used to schedule transmission of downlink data (such as PDSCH), or is used for other purposes, which are not limited by the embodiments of the present application.

[0206] FIG. 7 shows a schematic diagram of DCI scheduling data provided by an exemplary embodiment of the present application.

[0207] In (a) of FIG. 7, when the DCI is used to schedule downlink data, the DCI indicates transmission of the downlink data on a third transmission resource. The DCI can also indicate parameters of the downlink data transmission, which are used for the terminal device to perform downlink data reception based on the indicated parameters.

[0208] In (b) of FIG. 7, when the DCI is used to schedule uplink data, the DCI indicates transmission of the uplink data on a fourth transmission resource. The DCI can also indicate parameters of the uplink data transmission, which are used for the terminal device to perform uplink data transmission based on the indicated parameters.

[0209] In some embodiments, the DCI is carried by the PDCCH, the network device configures a search space in the second transmission resource by sending network configuration information, and the terminal device detects the PDCCH in the search space.

[0210] Optionally, the DCI is carried on the PDCCH or the PDSCH.

[0211] In some embodiments, at least one of the following information is determined based on the protocol predefined information or the network configuration information:

[0212] The DCI format corresponding to the DCI; the number of bits corresponding to the DCI; the radio network temporary identifier (RNTI) corresponding to the DCI; the encoding mode corresponding to the DCI; the coding rate corresponding to the DCI; the number of CCEs corresponding to the DCI; the aggregation level corresponding to the DCI; and the number of candidate PDCCHs associated with the aggregation level.

[0213] The number of bits corresponding to the DCI corresponds to the maximum number of bits, and the encoding mode includes a polar code, a low density parity check (LDPC) code, or a small block length encoding.

[0214] 2) The second transmission resource is used to transmit the first downlink data

[0215] In some embodiments, the second transmission resource is used to transmit downlink data, and the downlink data is carried by the PDSCH.

[0216] Since the transmission resource indication information and the transmission parameter indication information are not included in the first indication information, the transmission parameters corresponding to the downlink data are determined based on the protocol predefined information or the network configuration information.

[0217] In some embodiments, in the case where the first indication information is used to indicate that the first downlink data is transmitted on the second transmission resource, at least one of the following information is determined based on the protocol predefined information or the network configuration information:

[0218] a transport block size (TBS) corresponding to the first downlink data; a modulation mode or modulation and coding scheme (MCS) level corresponding to the first downlink data; a coding mode corresponding to the first downlink data; a coding rate corresponding to the first downlink data; an MCS table corresponding to the first downlink data; a number of layers corresponding to the first downlink data; antenna port information corresponding to the first downlink data; rate matching information corresponding to the first downlink data; physical resource block (PRB) quantity information included in a resource block group; PRB bundling size indication information; a transmission configuration indication (TCI) message; and DeModulation Reference Signal (DMRS) information corresponding to the first downlink data.

[0219] The TBS can be configured by the network device. If the data packet to be transmitted is smaller than the TBS, the data packet size can be equal to the TBS by filling redundant bits or the like.

[0220] Optionally, the DMRS information corresponding to the downlink data is determined based on protocol predefined information or network configuration information, and the DMRS information includes at least one of the following: a time domain position of the DMRS; a frequency domain position of the DMRS; a pattern of the DMRS; and DMRS sequence initialization information. Optionally, the DMRS information corresponding to the first downlink data is determined based on protocol predefined information, network configuration information, or the first indication information.

[0221] In some embodiments, the second transmission resource is only used for transmission of a small data packet, or the second transmission resource is only used for small data transmission (SDT).

[0222] 3) No transmission on the second transmission resource

[0223] In some embodiments, there is no transmission on the second transmission resource.

[0224] In some embodiments, the terminal determines whether there is transmission on the second transmission resource or whether the second transmission resource needs to be detected based on the detected first indication information. In this case, the indication content of the first indication information includes indication information indicating that there is no transmission on the second transmission resource.

[0225] In some embodiments, the terminal determines whether there is transmission on the second transmission resource or whether the second transmission resource needs to be detected based on whether the first indication information is detected. In this case, whether there is transmission on the second transmission resource is determined by whether the first indication information is detected.

[0226] In some embodiments, the terminal detects the first indication information on the first transmission resource, and the first indication information indicates no transmission on the second transmission resource, so the terminal does not need to detect on the second transmission resource.

[0227] In some embodiments, the terminal detects the first indication information on the first transmission resource, and if the terminal does not detect the first indication information, it indicates no transmission on the second transmission resource, so the terminal does not need to detect on the second transmission resource.

[0240] Taking the first indication information indicating the transmission parameter as an example, the first indication information is carried by a first sequence or at least one bit, and different first sequences or different values of the at least one bit can be used to indicate the transmission parameter.

[0241] Taking the second information indicating the transmission parameter as an example, at least five different indication manners can be used to indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource, wherein the first sequence is used to carry the first indication information.

[0242] Indication manner one: indicating the value of the transmission parameter corresponding to the transmission content on the second transmission resource based on the length of the first sequence;

[0243] Indication manner two: indicating the value of the transmission parameter corresponding to the transmission content on the second transmission resource based on the frequency domain resource corresponding to the first indication information;

[0247] For indication manner one: indicating the value of the transmission parameter corresponding to the transmission content on the second transmission resource based on the length of the first sequence;

[0248] Exemplarily, different lengths of the sequence correspond to different values or different states or different sequences, and further indicate different values of the transmission parameter corresponding to the transmission content on the second transmission resource. In some embodiments, the first parameter associated with the first indication information includes the length of the sequence. The values of the length of the sequence include A1 values, the values of the transmission parameter (such as the aggregation level, the number of CCEs, the number of resources, the modulation mode, the MCS table, the MCS level, the TBS) include A2 values, and the A1 values of the length of the sequence and the A2 values of the transmission parameter have an A-th correspondence relationship. Optionally, the A-th correspondence relationship is determined based on protocol predefined information or network configuration information. Wherein, A1 is an integer greater than or equal to 1, and A2 is an integer greater than or equal to 1.

[0249] For the indication mode two: the first indication information corresponding to the frequency domain resource indicates the value of the transmission parameter corresponding to the transmission content on the second transmission resource;

[0250] Exemplarily, different frequency domain resources corresponding to the first indication information correspond to different values or different states or different sequences, and further indicate different values of the transmission parameter corresponding to the transmission content on the second transmission resource.

In some embodiments, different frequency domain offsets correspond to different values of the transmission parameter.

[0251] For the indication mode three: the first indication information corresponding to the time domain resource indicates the value of the transmission parameter corresponding to the transmission content on the second transmission resource;

[0252] For example, the different time domain resources corresponding to the first indication information correspond to different values or different states or different sequences, thereby indicating different values of the transmission parameter corresponding to the transmission content on the second transmission resource. In some embodiments, the first parameter associated with the first indication information includes the time domain resource corresponding to the first indication information. The number of time domain resources available for transmitting the first indication information is C1, the value of the transmission parameter includes C2 values, and there is a Cth correspondence between the time domain resource corresponding to the first indication information and the value of the transmission parameter. Alternatively, the Cth correspondence is determined based on protocol pre-defined information or network configuration information; wherein C1 is an integer greater than or equal to 1, and C2 is an integer greater than or equal to 1.

[0254] For example, based on the sequence index corresponding to the first sequence to indicate different values of the transmission parameter corresponding to the transmission content on the second transmission resource. In some embodiments, the first parameter associated with the first indication information includes the sequence index corresponding to the first sequence. The sequence index corresponding to the sequence includes D1 values, the value of the transmission parameter includes D2 values, and there is a Dth correspondence between the sequence index corresponding to the sequence and the value of the transmission parameter, and the Dth correspondence is determined based on protocol pre-defined information or network configuration information; wherein D1 is an integer greater than or equal to 1, and D2 is an integer greater than or equal to 1.

[0255] For indication mode five: based on the sequence group index corresponding to the first sequence to indicate the value of the transmission parameter corresponding to the transmission content on the second transmission resource.

[0256] For example, different sequence groups corresponding to the first sequence correspond to different values or different states or different sequences, thereby indicating different values of the transmission parameter corresponding to the transmission content on the second transmission resource. In some embodiments, the first parameter associated with the first indication information includes the sequence group index corresponding to the first sequence. The sequence group index corresponding to the sequence includes E1 values, the value of the transmission parameter includes E2 values, and there is an Eth correspondence between the sequence group index corresponding to the sequence and the value of the transmission parameter, and the Eth correspondence is determined based on protocol pre-defined information or network configuration information; wherein E1 is an integer greater than or equal to 1, and E2 is an integer greater than or equal to 1. In some embodiments, the sequence group is composed of one or more sequences, the sequence group index is used to identify a sequence group, and the sequence group index is used to determine a group of related sequences.

[0257] determining the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the first indication information and / or the second information associated with the first indication information

[0258] In some embodiments, the value of the transmission parameter corresponding to the transmission content on the second transmission resource can be determined by the first indication information, so as to realize link adaptation adjustment on the DCI or downlink data transmitted on the second transmission resource. When the transmission parameter corresponds to different values, the required transmission resource quantity or size of the DCI or downlink data transmitted on the second transmission resource is also different.

[0259] In some embodiments, the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the first indication information, or the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the second information associated with the first indication information, or the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the information combination of the first indication information and the second information.

[0260] Taking the second information associated with the first indication information to determine the resource location as an example, as shown in part (a) of FIG. 8, if the size of the second transmission resource configured by the network device corresponds to the size of 8 CCEs, when the value of the transmission parameter is 2 CCEs, the DCI transmitted on the second transmission resource only needs to occupy 1 / 4 of the size of the second transmission resource. If the network device configures four UEs to share the second transmission resource, and the value of the transmission parameter of each UE is 2 CCEs, then the second transmission resource can be used to transmit the DCI of the four UEs at the same time at most. As shown in part (b) of FIG. 8, the network device configures the starting positions of the transmission resources corresponding to the DCI transmitted on the second transmission resource by the four UEs.

[0261] In some embodiments, the terminal device receives the first indication information on the first transmission resource, determines the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the second information associated with the first indication information, and the downlink transmission content is the transmission content in the second transmission resource; wherein the first indication information is used to indicate the transmission content on the second transmission resource and / or the value of the transmission parameter corresponding to the transmission content.

[0262] In some embodiments, the downlink transmission content is the transmission content in the second transmission resource, and the transmission resource corresponding to the downlink transmission content is a part of the second transmission resource. Optionally, the second transmission resource includes n sub-resources, and the transmission resource corresponding to the downlink transmission content is the first sub-resource of the n sub-resources. The resource location of the transmission resource corresponding to the downlink transmission content is a location in the second transmission resource, that is, the location of the first sub-resource in the second transmission resource.

[0263] In some embodiments, the first indication information is carried by a sequence, and the second information can also be replaced by information associated with the sequence, for example, the second information can be replaced by sequence information, or replaced by sequence attribute information, or replaced by a parameter corresponding to the sequence. The present application does not limit this. Optionally, the second information includes at least one of the following: a time domain resource corresponding to the first indication information, a frequency domain resource corresponding to the first indication information, a first parameter corresponding to the sequence carrying the first indication information. The first parameter includes at least one of the following: an initial value corresponding to the sequence, a cyclic shift value corresponding to the sequence, a group number corresponding to the sequence, a root sequence number in the group corresponding to the sequence, a sequence length corresponding to the sequence, and a sequence index corresponding to the sequence.

[0264] In some embodiments, the second information has a corresponding relationship with the resource location. The terminal device determines the second information associated with the first indication information according to the first indication information received on the first transmission resource, and further determines the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource.

[0265] In some embodiments, the resource location includes at least one of a resource start location, a resource end location, and a resource size. The resource start location includes at least one of a time domain start location, a frequency domain start location, and a logical resource start location. The resource end location includes at least one of a time domain end location, a frequency domain end location, and a logical resource unit end location. The resource size includes at least one of a time domain unit number, a frequency domain unit number, and a logical resource unit number.

[0266] Optionally, the following eight different determination methods can be used to determine the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource.

[0267] Determination method one: determining the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the time domain resource corresponding to the first indication information;

[0268] Determination method two: determining the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the frequency domain resource corresponding to the first indication information;

[0269] Determination method three: determining the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the first parameter corresponding to the first indication information;

[0270] Determination method four: determining the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the time domain resource and the frequency domain resource corresponding to the first indication information;

[0271] The fifth determination manner is to determine the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the time domain resource corresponding to the first indication information and the first parameter.

[0272] The sixth determination manner is to determine the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the frequency domain resource corresponding to the first indication information and the first parameter.

[0273] The seventh determination manner is to determine the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the time domain resource, the frequency domain resource corresponding to the first indication information and the first parameter.

[0274] The eighth determination manner is to determine the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the first indication information.

[0275] The first to seventh determination manners are to determine the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the second information associated with the first indication information. The eighth determination manner is to determine the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the first indication information.

[0276] The following is an example of determining the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the second information.

[0277] For the above first determination manner, in some embodiments, the second information includes the time domain resource corresponding to the first indication information, and different first indication information transmitted on different first transmission resources is associated with different time domain resources. It can also be understood that at least two first transmission resources are associated with different time domain resources, or a part of the first transmission resources are associated with different time domain resources. The present application does not limit this.

[0278] In some embodiments, the second information includes the time domain resource corresponding to the sequence, and the resource position is determined based on the time domain resource corresponding to the first indication information and the first correspondence relationship. The first correspondence relationship includes the correspondence relationship between the time domain resource and the resource position. In some embodiments, the first correspondence relationship includes the correspondence relationship between the time domain resource and the resource position, which can be understood as including the correspondence relationship between the time domain resource and the resource start position, or the correspondence relationship between the time domain resource and the resource end position, or the correspondence relationship between the time domain resource and the resource size. The first correspondence relationship is determined based on the protocol predefinition information or the network configuration information. Optionally, the first correspondence relationship includes one-to-one correspondence, many-to-one correspondence, and one-to-many correspondence.

[0279] For example, referring to FIG. 9, taking the sequence carrying as an example. The network device configures four first transmission resources for the terminal device, i.e., the second transmission resource is associated with the four first transmission resources, the sequence transmitted on the four first transmission resources is associated with four OFDM symbols, and each OFDM symbol can be used to transmit the sequence carrying the first indication information. As shown in part (a) of FIG. 9, the second transmission resource includes four time domain starting positions. The network device configures a one-to-one correspondence between the OFDM symbol transmitting the first indication information and the time domain starting position. Optionally, when the OFDM symbol is 0, it corresponds to the time domain starting position A on the second transmission resource; when the OFDM symbol is 1, it corresponds to the time domain starting position B on the second transmission resource; when the OFDM symbol is 2, it corresponds to the time domain starting position C on the second transmission resource; and when the OFDM symbol is 3, it corresponds to the time domain starting position D on the second transmission resource. As shown in part (b) of FIG. 9, the second transmission resource includes four frequency domain starting positions. The network device configures a one-to-one correspondence between the OFDM symbol transmitting the first indication information and the frequency domain starting position. Optionally, when the OFDM symbol is 0, it corresponds to the frequency domain starting position a on the second transmission resource; when the OFDM symbol is 1, it corresponds to the frequency domain starting position b on the second transmission resource; when the OFDM symbol is 2, it corresponds to the frequency domain starting position c on the second transmission resource; and when the OFDM symbol is 3, it corresponds to the frequency domain starting position d on the second transmission resource. As shown in part (c) of FIG. 9, the second transmission resource includes four logical resource starting positions, e.g., the second transmission resource includes four starting positions of CCEs. The network device configures a one-to-one correspondence between the OFDM symbol transmitting the first indication information and the logical resource starting position. Optionally, when the OFDM symbol is 0, it corresponds to the CCE index 0 on the second transmission resource; when the OFDM symbol is 1, it corresponds to the CCE index 1 on the second transmission resource; when the OFDM symbol is 2, it corresponds to the CCE index 2 on the second transmission resource; and when the OFDM symbol is 3, it corresponds to the CCE index 3 on the second transmission resource.

[0280] For the above determination mode two: in some embodiments, the second information includes a frequency domain resource corresponding to the first indication, and the first indication information transmitted on different first transmission resources is associated with different frequency domain resources. It can also be understood that there are at least two first transmission resources associated with different frequency domain resources, or a part of the first transmission resources are associated with different frequency domain resources. The present application does not limit this.

[0281] In some embodiments, the second information comprises a frequency domain resource corresponding to the first indication information, the resource position is determined based on the frequency domain resource corresponding to the first indication information and a second correspondence relationship, and the second correspondence relationship comprises a correspondence relationship between the frequency domain resource and the resource position. The second correspondence relationship comprises a correspondence relationship between the frequency domain resource and the resource position, which can be understood as that the second correspondence relationship comprises a correspondence relationship between the frequency domain resource and a resource start position, or the second correspondence relationship comprises a correspondence relationship between the frequency domain resource and a resource end position, or the second correspondence relationship comprises a correspondence relationship between the frequency domain resource and a resource size. The second correspondence relationship is determined based on protocol predefined information or network configuration information. Optionally, the second correspondence relationship comprises a one-to-one correspondence relationship, a many-to-one correspondence relationship, or a one-to-many correspondence relationship.

[0282] In some embodiments, the frequency domain resource of the sequence is represented by at least one of the following parameters: a frequency domain start position of the frequency domain resource, a frequency domain offset of the frequency domain resource, and a frequency domain resource size of the frequency domain resource.

[0283] In some embodiments, the frequency domain resource of the sequence is represented based on a frequency domain start position of the frequency domain resource, and different frequency domain start positions have a second correspondence relationship with different resource positions on the second transmission resource, i.e., different frequency domain start positions of the first transmission resource have the second correspondence relationship with different resource positions on the second transmission resource. Optionally, different frequency domain start positions have the second correspondence relationship with different resource start positions on the second transmission resource; or different frequency domain start positions have the second correspondence relationship with different resource end positions on the second transmission resource; or different frequency domain start positions have the second correspondence relationship with different resource sizes on the second transmission resource.

[0284] For example, with reference to FIG. 10, taking the first indication information carried by the sequence as an example, the network device configures four first transmission resources for the terminal device, i.e., the second transmission resource is associated with the four first transmission resources, the sequence transmitted by the four first transmission resources is associated with four frequency domain units, e.g., subbands, and each subband can be used to transmit a sequence carrying the first indication information. As shown in part (a) of FIG. 10, the second transmission resource includes four time domain starting positions. The network device configures a one-to-one correspondence between the subband carrying the first indication information and the time domain starting position of the second transmission resource. Alternatively, when the subband is 0, it corresponds to the time domain starting position A of the second transmission resource; when the subband is 1, it corresponds to the time domain starting position B of the second transmission resource; when the subband is 2, it corresponds to the time domain starting position C of the second transmission resource; and when the subband is 3, it corresponds to the time domain starting position D of the second transmission resource. As shown in part (b) of FIG. 10, the second transmission resource includes four frequency domain starting positions. The network device configures a one-to-one correspondence between the subband carrying the first indication information and the frequency domain starting position of the second transmission resource. Alternatively, when the subband is 0, it corresponds to the frequency domain starting position a of the second transmission resource; when the subband is 1, it corresponds to the frequency domain starting position b of the second transmission resource; when the subband is 2, it corresponds to the frequency domain starting position c of the second transmission resource; and when the subband is 3, it corresponds to the frequency domain starting position d of the second transmission resource.

[0285] In some embodiments, the frequency domain resource of the sequence is characterized by a frequency domain offset, and different frequency domain offsets have a second correspondence relationship with different resource positions on the second transmission resource, i.e., different frequency domain offsets of the first transmission resource have a second correspondence relationship with different resource positions on the second transmission resource. Alternatively, different frequency domain offsets have a second correspondence relationship with different resource starting positions on the second transmission resource; or different frequency domain offsets have a second correspondence relationship with different resource ending positions on the second transmission resource; or different frequency domain offsets have a second correspondence relationship with different resource sizes on the second transmission resource. The sequence is mapped to the first transmission resource in the form of a comb, and the frequency domain offset is used to indicate the offset corresponding to the comb resource occupied by the sequence in the first transmission resource. The first transmission resource can be referred to as a first comb resource. Alternatively, the first transmission resource includes n frequency domain units, and the n frequency domain units in the first transmission resource are arranged in the form of a comb.

[0286] For example, as shown in FIG. 11, taking the first indication information carried by the sequence as an example, the network device configures 4 first transmission resources for the terminal device, i.e., the second transmission resource is associated with 4 first transmission resources, and the 4 first transmission resources are all comb-shaped frequency domain resources, each of which corresponds to a different frequency domain offset. For example, the frequency domain offset of the comb-shaped frequency domain resource (a) is 0, the frequency domain offset of the comb-shaped frequency domain resource (b) is 1, the frequency domain offset of the comb-shaped frequency domain resource (c) is 2, and the frequency domain offset of the comb-shaped frequency domain resource (d) is 3. Each of the comb-shaped frequency domain resources can be used to transmit the sequence carrying the first indication information. The second transmission resource includes 4 time domain starting positions. The network device configures a one-to-one correspondence between the frequency domain offset and the time domain starting position. Alternatively, when the frequency domain offset is 0, it corresponds to the time domain starting position A on the second transmission resource; when the frequency domain offset is 1, it corresponds to the time domain starting position B on the second transmission resource; when the frequency domain offset is 2, it corresponds to the time domain starting position C on the second transmission resource; and when the frequency domain offset is 3, it corresponds to the time domain starting position D on the second transmission resource.

[0287] In some embodiments, the frequency domain resource size (or sequence length) of the frequency domain resource represents the frequency domain resource of the sequence, and different frequency domain resource sizes and different resource positions on the second transmission resource have a second correspondence relationship, i.e., different frequency domain resource sizes of the first transmission resource and different resource positions on the second transmission resource have a second correspondence relationship. Alternatively, different frequency domain resource sizes and different resource starting positions on the second transmission resource have a second correspondence relationship; or different frequency domain resource sizes and different resource ending positions on the second transmission resource have a second correspondence relationship; or different frequency domain resource sizes and different resource sizes on the second transmission resource have a second correspondence relationship.

[0288] For example, with reference to FIG. 12, the network device configures four first transmission resources for the terminal device, i.e., the second transmission resource is associated with the four first transmission resources, the sequence transmitted on the four first transmission resources is associated with four frequency domain units, e.g., subbands, and the sequence carrying the first indication information can occupy different numbers of subbands, e.g., one subband, two subbands, and four subbands. Alternatively, the longer the sequence carrying the first indication information, the more subbands it occupies. The second transmission resource includes four frequency domain starting positions. As shown in part (a) of FIG. 12, the frequency domain resource size for transmitting the first indication information is one subband, as shown in part (b) of FIG. 12, the frequency domain resource size for transmitting the first indication information is two subbands, and as shown in part (c) of FIG. 12, the frequency domain resource size for transmitting the first indication information is four subbands. Alternatively, when the frequency domain resource size is one, i.e., the sequence carrying the first indication information can occupy one subband, the first indication information can be transmitted based on any one of subband 0 to subband 3, corresponding to the frequency domain starting position d on the second transmission resource; when the frequency domain resource size is two, i.e., the sequence carrying the first indication information can occupy two subbands, the first indication information can be transmitted based on subband 0 and subband 1, or subband 1 and subband 2, or subband 2 and subband 3, corresponding to the frequency domain starting position c on the second transmission resource; when the frequency domain resource size is four, the first indication information can be transmitted based on subband 0, subband 1, subband 2, and subband 3, corresponding to the frequency domain starting position a on the second transmission resource.

[0289] For the above determination mode three: in some embodiments, the second information includes a first parameter corresponding to the sequence carrying the first indication information, and the sequence transmitted on different first transmission resources is associated with different first parameters. It can also be understood that at least two first transmission resources are associated with different first parameters, or a part of the first transmission resources are associated with different first parameters. The present application does not limit this.

[0290] In some embodiments, the second information includes a first parameter corresponding to the sequence carrying the first indication information, and the resource position is determined based on the first parameter corresponding to the sequence and a third correspondence relationship. The third correspondence relationship includes a correspondence relationship between the first parameter and the resource position. The third correspondence relationship includes a correspondence relationship between the first parameter and the resource starting position, or a correspondence relationship between the first parameter and the resource ending position, or a correspondence relationship between the first parameter and the resource size. The third correspondence relationship is determined based on protocol predefined information or network configuration information. Alternatively, the third correspondence relationship includes one-to-one correspondence, many-to-one correspondence, and one-to-many correspondence.

[0291] The terminal can determine the resource position corresponding to the transmission resource of the DCI or downlink data transmitted on the second transmission resource based on the first parameter corresponding to the detected sequence, for example, the resource position is the time domain starting position. Optionally, the network device configures a third correspondence relationship between the first parameter and the time domain starting position on the second transmission resource as shown in Table 5.

[0292] Table 5

[0293] For example, in combination with reference to FIG. 13, the network device configures 4 first transmission resources for the terminal device, that is, the second transmission resource is associated with 4 first transmission resources. The sequence transmitted on each first transmission resource is determined based on different first parameters, and the sequences transmitted on the 4 first transmission resources are determined based on 4 first parameters. For example, the network device configures 4 sequences that can be used to carry the first indication information, which correspond to sequence 0, sequence 1, sequence 2, and sequence 3 respectively. The 4 sequences can all be transmitted on the first transmission resource. The second transmission resource includes 4 time domain starting positions. Optionally, when the value of the first parameter is a first value, it corresponds to the time domain starting position A on the second transmission resource; when the value of the first parameter is a second value, it corresponds to the time domain starting position B on the second transmission resource; when the value of the first parameter is a third value, it corresponds to the time domain starting position C on the second transmission resource; and when the value of the first parameter is a fourth value, it corresponds to the time domain starting position D on the second transmission resource.

[0294] In some embodiments, the sequence carrying the first indication information is a pseudo-random sequence, and the value of the parameter Cinit is determined based on the value of the parameter Cinit. Optionally, the network configures 4 values of Cinit, for example, 17, 53, 127, and 131 respectively, based on which 4 sequences can be determined. The second transmission resource includes 4 logical resource starting positions, for example, the second transmission resource includes 4 starting positions of CCEs. For example, the 4 sequences are used to indicate different aggregation levels corresponding to the DCI transmitted on the second transmission resource: aggregation level 1, aggregation level 2, aggregation level 4, and aggregation level 8, and the number of CCEs corresponding to aggregation level 1, aggregation level 2, aggregation level 4, and aggregation level 8 is 1, 2, 4, and 8 respectively. Optionally, the total number of CCEs used to transmit DCI on the second transmission resource is 8, corresponding to CCE index 0 to CCE index 7 respectively. Optionally, the network device configures a third correspondence relationship between the value of the first parameter and the logical resource starting position, that is, the network configures a correspondence relationship between the value of Cinit and the starting position of the CCE on the second transmission resource for transmitting DCI, as shown in Table 6.

[0295] Table 6

[0296] For example, the second information includes a first parameter corresponding to the sequence. The network device configures four first transmission resources for the terminal device, i.e., the second transmission resource is associated with the four first transmission resources. The sequence transmitted on each first transmission resource is determined based on a different first parameter, and the sequences transmitted on the four first transmission resources are determined based on the four first parameters. The first parameter is based on the starting position of the CCE. Optionally, the total number of CCEs used to transmit the DCI on the second transmission resource is 8, corresponding to indexes 0 to 7. As shown in Table 6 above, when the value of the first parameter is 17 (corresponding to the first sequence), the aggregation level of the DCI indicated by the first parameter is 1, i.e., one CCE is needed to carry the DCI, corresponding to the CCE index 7 on the second transmission resource, and the DCI is mapped to the CCE with index 7; when the value of the first parameter is 53 (corresponding to the second sequence), the aggregation level of the DCI indicated by the first parameter is 2, i.e., two CCEs are needed to carry the DCI, corresponding to the CCE index 4 on the second transmission resource, and the DCI is mapped to the two CCEs with indexes 4 and 5; when the value of the first parameter is 127 (corresponding to the third sequence), the aggregation level of the DCI indicated by the first parameter is 4, i.e., four CCEs are needed to carry the DCI, corresponding to the CCE index 4 on the second transmission resource, and the DCI is mapped to the CCEs with indexes 4, 5, 6, and 7; and when the value of the first parameter is 151 (corresponding to the fourth sequence), the aggregation level of the DCI indicated by the first parameter is 8, i.e., eight CCEs are needed to carry the DCI, corresponding to the CCE index 0 on the second transmission resource, and the DCI is mapped to the eight consecutive CCEs starting from index 0.

[0297] It should be noted that the above determination mode one to determination mode three respectively introduce the method of determining the resource position of the transmission resource of the downlink transmission content on the second transmission resource based on the time domain resource, the frequency domain resource and the first parameter corresponding to the first indication information. It should be understood that the above determination modes can be used in combination, and after combination, they are respectively determination mode four to determination mode seven, which will not be described here.

[0298] The following will be described based on the determination of the resource position of the transmission resource of the downlink transmission content in the second transmission resource based on the first indication information.

[0299] For the above determination mode eight, in some embodiments, the resource position of the transmission resource of the downlink transmission content in the second transmission resource is determined based on the first indication information. The resource position includes at least one of the resource starting position, the resource ending position, and the resource size.

[0300] In some embodiments, the first indication information is carried by a sequence, or the first indication information is carried by a bit sequence including L bits, where L is an integer greater than or equal to 1. The resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the first indication information, or it can also be understood that the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the sequence or at least one bit carrying the first indication information.

[0301] In some embodiments, the network device configures at least two first transmission resources corresponding to one second transmission resource, that is, one second transmission resource is associated with at least two first transmission resources. Each of the at least two first transmission resources can be used to transmit the first indication information. Optionally, the first indication information has a corresponding relationship with the resource position, or it can also be understood that the sequence or at least one bit carrying the first indication information has a corresponding relationship with the resource position. The eighth corresponding relationship is determined based on protocol pre-defined information or network configuration information. Optionally, the eighth corresponding relationship includes one-to-one correspondence, many-to-one correspondence, and one-to-many correspondence.

[0302] For example, if the first indication information is carried by a sequence, sequence 0 represents resource position 0, sequence 1 represents resource position 1, and sequence 2 represents resource position 2.

[0303] The following is an example of determining the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the first indication information and the second information.

[0304] In some embodiments, the information combination of the first indication information and the second information associated with the first indication information has a corresponding relationship with the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource. The resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the information combination of the first indication information and the second information.

[0305] In some embodiments, the second information associated with the first indication information includes at least one of a time domain resource corresponding to the first indication information, a frequency domain resource corresponding to the first indication information, and a first parameter corresponding to a sequence carrying the first indication information. The first parameter includes at least one of an initial value corresponding to the sequence, a cyclic shift value corresponding to the sequence, a group number corresponding to the sequence, an intra-group root sequence number corresponding to the sequence, a sequence length corresponding to the sequence, and a sequence index corresponding to the sequence.

[0306] Optionally, the second information can be considered to have eight kinds, i.e., at least one of the first information including time domain resources corresponding to the first indication information, frequency domain resources corresponding to the first indication information, an initial value corresponding to the sequence, a cyclic shift value corresponding to the sequence, a group number corresponding to the sequence, an intra-group root sequence number corresponding to the sequence, a sequence length corresponding to the sequence, and a sequence index corresponding to the sequence.

[0307] In some embodiments, the first indication information is carried by a sequence, and based on the information combination of the first indication information and the at least one first information, the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined. It can be understood that, based on the information combination of the sequence carrying the first indication information and the first information, the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined. The at least one first information can be considered to be at least one of the above eight kinds of information.

[0308] For example, based on the information combination of the first indication information and the time domain resource corresponding to the first information, the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined. For example, sequence 0 and time domain position 0 of the first transmission resource represent resource position 0 in the second transmission resource; sequence 0 and time domain position 1 of the first transmission resource represent resource position 1 in the second transmission resource; sequence 1 and time domain position 0 of the first transmission resource represent resource position 2 in the second transmission resource; and sequence 1 and time domain position 1 of the first transmission resource represent resource position 3 in the second transmission resource.

[0309] It should be noted that, based on the information combination of the first indication information and the first information, the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource can be used in combination with at least one of the above “determination mode eight” and “determination mode one to determination mode seven”, which will not be described here.

[0310] In the related art, the terminal device is always in a detection state, which consumes the energy of the terminal device, and the terminal device cannot determine the transmission resource corresponding to the downlink data. In this application, the network device configures the first transmission resource to transmit the first indication information, and the terminal device determines the transmission information on the second transmission resource by receiving the first indication information. However, in the case of poor signal, the terminal device can not accurately receive the first indication information, therefore, the application configures multiple first transmission resources to repeatedly transmit the first indication information, which is conducive to improving the success rate of reception and improving the reliability of the first indication information detection.

[0373] In some embodiments, the network device configures N first transmission resources for the terminal device, and the N first transmission resources correspond to a second transmission resource, that is, the second transmission resource is associated with the N first transmission resources, and N is a positive integer greater than 1. Optionally, the index information corresponding to the N first transmission resources is 0, 1, 2, 3, …, N-1, respectively.

[0374] For example, as shown in the part (a) of FIG. 17, the index information corresponding to the first transmission resources on the four symbols from left to right is 0, 1, 2, and 3, respectively, i.e., symbol 0 corresponds to index 0, symbol 1 corresponds to index 1, symbol 2 corresponds to index 2, and symbol 3 corresponds to index 3. As shown in the part (b) of FIG. 17, the index information corresponding to the first transmission resources on the four subbands from bottom to top is 0, 1, 2, and 3, respectively, i.e., subband 0 corresponds to index 0, subband 1 corresponds to index 1, subband 2 corresponds to index 2, and subband 3 corresponds to index 3. As shown in the part (c) of FIG. 17, the index information corresponding to the first transmission resources on the four symbols in the order of frequency domain first and time domain second (or time domain first and frequency domain second) is 0, 1, 2, and 3, respectively, i.e., the lowest position of the frequency domain on symbol 0 corresponds to index 0, the highest position of the frequency domain on symbol 0 corresponds to index 1, the lowest position of the frequency domain on symbol 1 corresponds to index 2, and the highest position of the frequency domain on symbol 1 corresponds to index 3.

[0375] In some embodiments, the first information includes index information, and the index information has a corresponding relationship with the at least two first transmission resources, i.e., when the index information is X, it corresponds to the at least two first transmission resources, which can be understood as that when the index information is X, the first indication information is transmitted through the at least two first transmission resources corresponding to the index information, and X is a positive integer. The network device configures the corresponding relationship between the index information and the first transmission resources (represented based on the first transmission resource index) as shown in Table 7.

[0376] Table 7

[0377] For example, the first information is used to configure or indicate the at least one first transmission resource, and the first transmission resource is used to transmit the first indication information. The first information includes index information, and the index information has a corresponding relationship with the first transmission resource.

[0378] Optionally, when the index information is 0, the corresponding first transmission resource is index 0, i.e., the first indication information is transmitted through the first transmission resource of index 0; when the index information is 1, the corresponding first transmission resource is index 1, i.e., the first indication information is transmitted through the first transmission resource of index 1; when the index information is 2, the corresponding first transmission resource is index 2, i.e., the first indication information is transmitted through the first transmission resource of index 2; and when the index information is 3, the corresponding first transmission resource is index 3, i.e., the first indication information is transmitted through the first transmission resource of index 3. When the index information is 0 to 3, the number of the first transmission resources configured or indicated is 1, i.e., the first indication information is transmitted on one first transmission resource.

[0379] For example, the first information is used for configuring or indicating at least two first transmission resources for repeatedly transmitting the first indication information. The first information comprises index information, which has a corresponding relationship with the at least two first transmission resources.

[0380] Optionally, when the index information is 4, the corresponding first transmission resources are index 0 and index 1, that is, the first indication information is repeatedly transmitted through the first transmission resource of index 0 and the first transmission resource of index 1, which can also be understood as that the first indication information is repeatedly transmitted through the first transmission resources of index 0 and index 1 for a repetition number of 2. When the index information is 5, the corresponding first transmission resources are index 0 and index 2, that is, the first indication information is repeatedly transmitted through the first transmission resources of index 0 and index 2 for a repetition number of 2. When the index information is 6, the corresponding first transmission resources are index 0 and index 3, that is, the first indication information is repeatedly transmitted through the first transmission resources of index 0 and index 3 for a repetition number of 2. When the index information is 7, the corresponding first transmission resources are index 1 and index 2, that is, the first indication information is repeatedly transmitted through the first transmission resources of index 1 and index 2 for a repetition number of 2. When the index information is 8, the corresponding first transmission resources are index 1 and index 3, that is, the first indication information is repeatedly transmitted through the first transmission resources of index 1 and index 3 for a repetition number of 2. When the index information is 9, the corresponding first transmission resources are index 2 and index 3, that is, the first indication information is repeatedly transmitted through the first transmission resources of index 2 and index 3 for a repetition number of 2. When the index information is 4 to 9, the number of the first transmission resources configured or indicated is 2, that is, the first indication information is repeatedly transmitted on two first transmission resources.

[0381] Optionally, when the index information is 10, the corresponding first transmission resource is index 0, index 1 and index 2, that is, the first indication information performs repeated transmission with a repetition number of 3 on the first indication information through the first transmission resource of index 0, index 1 and index 2; when the index information is 11, the corresponding first transmission resource is index 0, index 1 and index 3, that is, the first indication information performs repeated transmission with a repetition number of 3 on the first indication information through the first transmission resource of index 0, index 1 and index 3; when the index information is 12, the corresponding first transmission resource is index 0, index 2 and index 3, that is, the first indication information performs repeated transmission with a repetition number of 3 on the first indication information through the first transmission resource of index 0, index 2 and index 3; when the index information is 13, the corresponding first transmission resource is index 1, index 2 and index 3, that is, the first indication information performs repeated transmission with a repetition number of 3 on the first indication information through the first transmission resource of index 1, index 2 and index 3. When the index information is 10 to 13, the number of the first transmission resource is configured or indicated to be 3, that is, the first indication information is repeatedly transmitted on three first transmission resources.

[0382] Optionally, when the index information is 14, the corresponding first transmission resource is index 0, index 1, index 2 and index 3, that is, the first indication information performs repeated transmission with a repetition number of 4 on the first indication information through the first transmission resource of index 0, index 1, index 2 and index 3. When the index information is 14, the number of the first transmission resource is configured or indicated to be 4, that is, the first indication information is repeatedly transmitted on four first transmission resources.

[0383] It should be noted that the above table 7 is only an exemplary description of the correspondence between the index information and the first transmission resource index, and the method in the embodiments of the present application is not limited to the correspondence in table 7. In some embodiments, the correspondence configured by the network only includes part of the content in the above table, such as only including any 2 rows in the above table; in some embodiments, the index information included in the correspondence configured by the network is K, and the corresponding first transmission resource index is L, wherein K and L are integers greater than or equal to 1.

[0384] In some embodiments, the network device configures the correspondence between the index information and the at least two first transmission resources based on broadcast information or RRC signaling. Optionally, the first information is carried in at least one of the following messages: RRC; MAC CE; DCI. The terminal device receives the first information, and determines the number and position of the at least two first transmission resources based on the index information in the first information.

[0385] For example, the network device configures four first transmission resources for the terminal device, i.e., the second transmission resource is associated with four first transmission resources. As shown in part (a) of FIG. 17, the sequence of the four first transmission resources is associated with four symbols, and the indexes of the four first transmission resources from left to right are 0, 1, 2, and 3, respectively, i.e., the symbol 0 corresponds to the index 0, the symbol 1 corresponds to the index 1, the symbol 2 corresponds to the index 2, and the symbol 3 corresponds to the index 3. Optionally, the network device configures the correspondence between the index information and the two first transmission resources based on the broadcast information or the RRC signaling, as shown in Table 8.

[0386] Table 8

[0387] For example, the first information includes the index information. For example, when the index information is 0, the corresponding first transmission resource is the index 0 and the index 1, i.e., the first indication information is repeatedly transmitted twice through the first transmission resources with the index 0 and the index 1. As shown in part (a) of FIG. 17, the index 0 corresponds to the symbol 0, and the index 1 corresponds to the symbol 1, i.e., the first indication information is repeatedly transmitted through the first transmission resources on the symbol 0 and the symbol 1. When the first indication information is carried based on the sequence, the repeated transmission of the first indication information through the first transmission resources on the symbol 0 and the symbol 1 can also be understood as the repeated transmission of the sequence carrying the first indication information through the first transmission resources on the symbol 0 and the symbol 1. Optionally, the terminal device receives the first information sent by the network device, and determines to detect the first indication information on the first transmission resource of the symbol 0, or on the first transmission resource of the symbol 1, or on the first transmission resources of the symbol 0 and the symbol 1 based on the first information. Optionally, the terminal device performs combined detection on the first transmission resources on the symbol 0 and the symbol 1.

[0388] The final detection result of the first indication information is determined based on the detection result.

[0389] In some embodiments, the network device configures the second transmission resource to be associated with a plurality of first transmission resources, and when at least two first transmission resources in the plurality of first transmission resources are used for repeatedly transmitting the first indication information, the terminal device detects the first indication information on the at least two first transmission resources, and obtains detection results of the at least two first indication information, wherein each first transmission resource corresponds to one detection result.

[0390] Optionally, if the detection results corresponding to the at least two detection results are the same, the terminal device determines the detection results corresponding to the at least two detection results as the final detection result. Optionally, if the detection results corresponding to the at least two detection results are different, the terminal device determines the final detection result of the first indication information in the at least two detection results based on the third information.

[0391] In some embodiments, when the at least two detection results are in one-to-one correspondence with the at least two first transmission resources, it can be understood that each of the at least two first transmission resources corresponds to one detection result, and it can also be understood that the detection results of the terminal device on the at least two first transmission resources are different for the first indication information.

[0392] In some embodiments, the terminal device determines the final detection result of the first indication information from the at least two detection results based on the third information, including but not limited to at least one of the following:

[0393] determining the final detection result of the first indication information from the at least two detection results based on the signal quality corresponding to the at least two first transmission resources;

[0394] determining the final detection result of the first indication information from the at least two detection results based on the peak value of the detection of the sequence transmitted by the at least two first transmission resources, the sequence being used to carry the first indication information;

[0395] determining the final detection result of the first indication information from the at least two detection results based on the number of the same detection result.

[0396] In some embodiments, the third information includes at least one of the following: the signal quality corresponding to the at least two first transmission resources; the peak value of the sequence transmitted by the at least two first transmission resources; and the number of the same detection result.

[0397] Optionally, the following three different detection methods can be used to determine the final detection result of the first indication information. The final detection result of the first indication information can be determined based on at least one of the following three detection methods.

[0398] Detection method one: determining based on the signal quality corresponding to the at least two first transmission resources;

[0399] Detection method two: determining based on the detection peak value of the sequence transmitted on the at least two first transmission resources;

[0400] Detection method three: determining based on the number of the same detection result.

[0401] The following will introduce the three different detection methods respectively.

[0402] For the above detection method one:

[0403] In some embodiments, the terminal device measures the at least two first transmission resources, and determines the first indication information based on the signal quality corresponding to the at least two first transmission resources, i.e., determines the final detection result of the first indication information from the at least two detection results based on the signal quality corresponding to the at least two first transmission resources.

[0404] In some embodiments, the terminal device measures the signal quality corresponding to the at least two first transmission resources. Optionally, the signal quality comprises at least one of: RSRP (Reference signal received power), RSRQ (Reference signal received quality), RSSI (Received signal strength indicator), SINR (Signal-to-noise and interference ratio), SNR (Signal-to-noise ratio).

[0405] In some embodiments, based on the signal quality corresponding to the at least two first transmission resources, the terminal device determines the final detection result of the first indication information from the at least two detection results. The final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource with the best signal quality.

[0406] For example, the network device configures two first transmission resources to repeatedly transmit the first indication information, and the first indication information is used to indicate the transmission information on the second transmission resource. For example, the transmission information is whether to transmit DCI on the second transmission resource, i.e., the first indication information is used to indicate whether to transmit DCI on the second transmission resource. Table 9 shows a way of determining the final detection result of the first indication information based on the signal quality.

[0407] Table 9

[0408] For example, in combination with Table 9 described above, the network device configures two first transmission resources to repeatedly transmit the first indication information, and the first indication information is used to indicate whether to transmit DCI on the second transmission resource. Optionally, the terminal device detects the first indication information on the two first transmission resources, and the detection results are respectively: the detection result on the first first transmission resource is that there is no DCI transmission on the second transmission resource, and the detection result on the second first transmission resource is that there is DCI transmission on the second transmission resource. Optionally, the terminal device respectively measures the signal quality corresponding to the two first transmission resources. The signal quality corresponding to the first first transmission resource is the first signal quality, and the signal quality corresponding to the second first transmission resource is the second signal quality. Optionally, the final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource with the best signal quality.

[0409] If the signal quality of the first signal quality is the best, the final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource of the first signal quality, that is, the final detection result is that there is no DCI transmission on the second transmission resource. If the signal quality of the second signal quality is the best, the final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource of the second signal quality, that is, the final detection result is that there is DCI transmission on the second transmission resource.

[0410] For example, the signal quality is an RSRP measurement result, the signal quality corresponding to the first first transmission resource is a first RSRP measurement result, and the signal quality corresponding to the second first transmission resource is a second RSRP measurement result. If the signal quality of the first signal quality is the best, that is, the first RSRP measurement result is the best, the final detection result is that there is no DCI transmission on the second transmission resource; if the signal quality of the second signal quality is the best, that is, the second RSRP measurement result is the best, the final detection result is that there is DCI transmission on the second transmission resource.

[0411] It should be noted that the above Table 9 is only an exemplary description of determining the final detection result of the first indication information based on the signal quality, and the method in the embodiments of the present application is not limited to the corresponding relationship in Table 9. In some embodiments, the corresponding relationship configured by the network only includes part of the content in the above table, such as only including any 2 rows in the above table; in some embodiments, the transmission information included in the corresponding relationship configured by the network is K, and the corresponding detection result and signal quality are also K, where K is an integer greater than or equal to 1.

[0412] For the above detection mode two:

[0413] In some embodiments, the first indication information is carried based on a sequence or at least one bit (bit sequence). The terminal device can detect the sequence through sequence correlation processing, and the peak value of sequence detection is the maximum value of sequence correlation processing.

[0414] In some embodiments, the terminal device measures at least two first transmission resources, and determines the first indication information based on the detection peak value of the sequence transmitted by the at least two first transmission resources, that is, based on the detection peak value of the sequence transmitted by the at least two first transmission resources, determines the final detection result of the first indication information in the at least two detection results. Wherein, the detection peak value of the sequence can be considered as the peak value corresponding to the detection of the sequence.

[0415] In some embodiments, the final detection result of the first indication information is determined among the at least two detection results based on the detected peak values of the sequence of the at least two first transmission resource transmissions. The final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource with the highest detected peak value of the sequence of the at least two first transmission resource transmissions. The sequence is used to carry the first indication information.

[0416] For example, the network device configures two first transmission resources to repeatedly transmit the first indication information, and the first indication information is used to indicate transmission information on the second transmission resource. For example, the transmission information is whether DCI is transmitted on the second transmission resource, i.e., the first indication information is used to indicate whether DCI is transmitted on the second transmission resource. Table 10 shows a manner of determining the final detection result of the first indication information based on the detected peak values of the sequence.

[0417] Table 10

[0418] For example, in combination with Table 10 described above, the network device configures two first transmission resources to repeatedly transmit the first indication information, and the first indication information is used to indicate whether DCI is transmitted on the second transmission resource. Optionally, the terminal device detects the first indication information on the two first transmission resources, and the detection results are that there is no DCI transmission on the second transmission resource on the first first transmission resource and there is DCI transmission on the second transmission resource on the second first transmission resource. Optionally, the terminal device measures the detected peak values of the sequence of the two first transmission resource transmissions. The detected peak value of the sequence of the first first transmission resource transmission is the first peak value, and the detected peak value of the sequence of the second first transmission resource transmission is the second peak value. Optionally, the final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource with the highest detected peak value of the sequence of the at least two first transmission resource transmissions.

[0419] If the first peak value is the highest, the final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource of the first peak value, i.e., the final detection result is that there is no DCI transmission on the second transmission resource. If the second peak value is the highest, the final detection result of the first indication information is the detection result of the first indication information corresponding to the first transmission resource of the second peak value, i.e., the final detection result is that there is DCI transmission on the second transmission resource.

[0420] It should be noted that the above Table 10 is only an exemplary illustration of determining the final detection result of the first indication information based on the peak value of the sequence, and the method in the embodiments of the present application is not limited to the correspondence relationship in Table 10. In some embodiments, the network-configured correspondence relationship only includes part of the content in the above table, such as only including any 2 rows in the above table; in some embodiments, the transmission information included in the network-configured correspondence relationship is K, and the corresponding detection result and the peak value of the sequence are also K, where K is an integer greater than or equal to 1.

[0421] For the above detection method three:

[0422] In some embodiments, the terminal device measures at least two first transmission resources, and determines the first indication information based on the number of the same kind of detection result, that is, determines the final detection result of the first indication information in the at least two detection results based on the number of the same kind of detection result.

[0423] In some embodiments, the terminal device measures at least two first transmission resources, that is, the terminal device measures the first indication information transmitted on the at least two first transmission resources. Optionally, the detection result of the first indication information on the at least two first transmission resources is N kinds of detection results. Wherein, N is a positive integer greater than or equal to 1. If N is 1, the detection result of the first indication information on the at least two first transmission resources is one kind of detection result, and the final detection result is the kind of detection result. If N is greater than 1, the detection result of the first indication information on the at least two first transmission resources is multiple kinds of detection results, and the final detection result is the same kind of detection result with the largest number in the multiple kinds of detection results.

[0424] In some embodiments, the same kind of detection result means that the first transmission resource in the at least two first transmission resources corresponds to the same kind of detection result, which can also be understood as that the detection result of the terminal device on the first indication information on the at least two first transmission resources is the same kind of detection result, which can also be understood as that the detection result corresponding to the first transmission resource in the at least two first transmission resources is the same, and which can also be understood as that the detection result of the terminal device on the first indication information on the at least two first transmission resources is the same detection result.

[0425] In some embodiments, the final detection result of the first indication information is determined in the at least two detection results based on the number of the same kind of detection result. The final detection result of the first indication information is the same kind of detection result with the largest number in the at least two detection results.

[0426] For example, the network device configures three first transmission resources to repeatedly transmit the first indication information, and the first indication information is used to indicate the transmission information on the second transmission resource. For example, the transmission information is whether to transmit the DCI on the second transmission resource, i.e., the first indication information is used to indicate whether to transmit the DCI on the second transmission resource. Table 11 shows a manner of determining the final detection result of the first indication information based on the number of the same detection result.

[0427] Table 11

[0428] For example, in combination with Table 11, the network device configures three first transmission resources to repeatedly transmit the first indication information, and the first indication information is used to indicate whether to transmit the DCI on the second transmission resource. Optionally, the terminal device detects the first indication information on the two first transmission resources, and the detection results are as follows: the detection result of the first first transmission resource is that there is no DCI transmission on the second transmission resource, the detection result of the second first transmission resource is that there is no DCI transmission on the second transmission resource, and the detection result of the third first transmission resource is that there is DCI transmission on the second transmission resource.

[0429] Optionally, the terminal device determines the number of the same detection result in the three first transmission resources respectively. The first kind of detection result is that there is no DCI transmission on the second transmission resource, and the second kind of detection result is that there is DCI transmission on the second transmission resource. The number of the first kind of detection result is 2, i.e., the number of the second transmission resource without DCI transmission is 2; the number of the second kind of detection result is 1, i.e., the number of the second transmission resource with DCI transmission is 1. Optionally, the final detection result of the first indication information is the same kind of detection result with the largest number in the at least two detection results. That is, the final detection result of the first indication information is that there is no DCI transmission on the second transmission resource.

[0430] It should be noted that the above Table 11 is only an example of determining the final detection result of the first indication information based on the number of the same detection result, and the method in the embodiments of the present application is not limited to the corresponding relationship in Table 11. In some embodiments, the network configuration corresponding relationship only includes part of the content in the above table, such as only including any 2 rows in the above table; in some embodiments, the transmission information included in the network configuration corresponding relationship is K, and the corresponding detection result and the number of the detection result are also K, wherein K is an integer greater than or equal to 1.

[0431] The first indication information and / or the second information associated with the first indication information is used to indicate the transmission information on the second transmission resource.

[0432] In some embodiments, the transmission resource configured by the network device to the terminal device comprises at least a first transmission resource and a second transmission resource. Optionally, the first transmission resource and the second transmission resource comprise a one-to-many relationship, i.e., a plurality of first transmission resources correspond to one second transmission resource, or it can be understood that one second transmission resource is associated with a plurality of first transmission resources.

[0433] In some embodiments, the plurality of first transmission resources can be respectively used for repeatedly transmitting different first indication information. The plurality of first transmission resources are configured to be used by one terminal, or used by a plurality of terminals respectively, or used by a plurality of terminals jointly.

[0434] In some embodiments, the plurality of first transmission resources are divided into at least two groups, and the at least two first transmission resources are one group of the at least two groups of first transmission resources.

[0435] In some embodiments, the at least two groups of first transmission resources satisfy at least one of the following: the time domain resources corresponding to the at least two groups of first transmission resources are different; the frequency domain resources corresponding to the at least two groups of first transmission resources are different; and the sequences transmitted on the at least two groups of first transmission resources are different, wherein the sequence is used to carry the first indication information.

[0436] In some embodiments, only one group of first transmission resources in the at least two groups is used for transmission in the current repetition transmission process, or it can be understood that different groups of first transmission resources in the at least two groups are used in different repetition transmission processes. For example, the first group of first transmission resources is used to perform repetition transmission in the current repetition transmission process, and the second group of first transmission resources is used to perform repetition transmission in another repetition transmission process.

[0437] In some embodiments, the first information is further used to configure or indicate the correspondence between the first indication information and / or the second information associated with the first indication information and the indicated transmission information.

[0438] In some embodiments, the first indication information and / or the second information associated with the first indication information is used to indicate the transmission information on the second transmission resource, and the terminal device determines the transmission information on the second transmission resource according to the first indication information and / or the second information based on the detected first indication information. The second information associated with the first indication information comprises at least one of the time domain resource corresponding to the first indication information, the frequency domain resource corresponding to the first indication information, and the first parameter corresponding to the sequence carrying the first indication information. The first parameter comprises at least one of the initial value corresponding to the sequence, the cyclic shift value corresponding to the sequence, the group number corresponding to the sequence, the intra-group root sequence number corresponding to the sequence, the sequence length corresponding to the sequence, and the sequence index corresponding to the sequence.

[0439] In some embodiments, the second information can be considered to have eight kinds, that is, the second information includes at least one of the time domain resource corresponding to the first indication information, the frequency domain resource corresponding to the first indication information, the initial value corresponding to the sequence, the cyclic shift value corresponding to the sequence, the group number corresponding to the sequence, the intra-group root sequence number corresponding to the sequence, the sequence length corresponding to the sequence, and the sequence index corresponding to the sequence.

[0440] In some embodiments, the time domain resource corresponding to the first indication information can be understood as the time domain resource corresponding to the repeatedly transmitted first indication information, or can be understood as the time domain resource corresponding to the at least two first transmission resources. The frequency domain resource corresponding to the first indication information can be understood as the frequency domain resource corresponding to the repeatedly transmitted first indication information, or can be understood as the frequency domain resource corresponding to the at least two first transmission resources. The first parameter corresponding to the sequence carrying the first indication information can be understood as the first parameter corresponding to the sequence carrying the repeatedly transmitted first indication information, or can be understood as the sequence parameter corresponding to the same sequence transmitted by the at least two first transmission resources.

[0441] In some embodiments, the transmission information on the second transmission resource includes at least one of the following information:

[0442] • There is DCI or downlink data transmission in the second transmission resource;

[0443] • Transmission content in the second transmission resource;

[0444] • Transmission parameter corresponding to the transmission content in the second transmission resource;

[0445] • Resource location of the transmission resource in the second transmission resource, the transmission resource being the resource occupied by the transmission content in the second transmission resource.

[0446] In some embodiments, the transmission information on the second transmission resource is one kind. Optionally, the first indication information and / or the second information associated with the first indication information indicates one kind of transmission information on the second transmission resource. The one kind of transmission information includes any one of the following: there is DCI or downlink data transmission in the second transmission resource, the transmission content in the second transmission resource, the transmission parameter corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0447] In some embodiments, the transmission information on the second transmission resource is at least two, each of which is indicated by one information or information combination of the first indication information and the at least one second information, and different transmission information is indicated by different information or information combination of the first indication information and the at least one second information. Optionally, the at least two transmission information on the second transmission resource is indicated based on the first indication information and / or the second information associated with the first indication information. The at least two transmission information includes at least two of DCI or downlink data transmission in the second transmission resource, transmission content in the second transmission resource, transmission parameter corresponding to the transmission content in the second transmission resource, and resource location of the transmission resource in the second transmission resource.

[0448] Scenario one: one transmission information on the second transmission resource is indicated based on the first indication information and / or the second information associated with the first indication information.

[0449] Scenario two: at least two transmission information on the second transmission resource is indicated based on the first indication information and / or the second information associated with the first indication information.

[0450] Optionally, the first indication information is the first indication information repeatedly transmitted on the at least two first transmission resources.

[0451] The following will introduce different cases indicated by the first indication information and / or the second information associated with the first indication information.

[0452] Scenario one: one transmission information on the second transmission resource is indicated based on the first indication information and / or the second information associated with the first indication information.

[0453] In some embodiments, the first transmission resource and the second transmission resource include a one-to-many relationship, that is, a plurality of first transmission resources correspond to one second transmission resource, or it can be understood that one second transmission resource is associated with a plurality of first transmission resources.

[0454] In some embodiments, the network device configures at least two first transmission resources for repeatedly transmitting the first indication information, and the first indication information is used to indicate the transmission content on the second transmission resource. The at least two first transmission resources are all or part of the plurality of first transmission resources. Optionally, the plurality of first transmission resources are divided into at least two groups, and the at least two first transmission resources are one group of the at least two groups of first transmission resources. Different groups of time domain resources and / or frequency domain resources can be understood as different first transmission resources on different groups corresponding to different time domain resources and / or frequency domain resources.

[0455] In some embodiments, the first indication information and / or the second information associated with the first indication information indicates one transmission information on the second transmission resource. The one transmission information includes any one of the following: DCI or downlink data transmission in the second transmission resource, transmission content in the second transmission resource, transmission parameter corresponding to the transmission content in the second transmission resource, and resource location of the transmission resource in the second transmission resource.

[0456] 1. The first indication information indicates one transmission information on the second transmission resource

[0457] In some embodiments, the first indication information is based on a sequence. The first indication information indicating one transmission information on the second transmission resource can also be understood as the sequence indicating one transmission information on the second transmission resource, or the sequence carrying the first indication information indicating one transmission information on the second transmission resource.

[0458] In some embodiments, the one transmission information includes any one of the following: DCI or downlink data transmission in the second transmission resource, transmission content in the second transmission resource, transmission parameter corresponding to the transmission content in the second transmission resource, and resource location of the transmission resource in the second transmission resource.

[0459] In some embodiments, the network device configures N first transmission resources corresponding to the second transmission resource, i.e., the second transmission resource is associated with N first transmission resources, and N is a positive integer greater than 1. Optionally, the index information corresponding to the N first transmission resources is 0, 1, 2, 3, …, N-1, respectively.

[0460] Taking the transmission content on the second transmission resource as an example of the one transmission information. For example, in combination with reference to FIG. 18, the network device configures 2 first transmission resources corresponding to one second transmission resource, i.e., one second transmission resource is associated with 2 first transmission resources. The 2 first transmission resources are used to transmit a sequence carrying the first indication information. The sequence transmitted on the 2 first transmission resources is sequence 0. The index information corresponding to the 2 first transmission resources from left to right is index 0 and index 1, respectively. Optionally, the 2 first transmission resources are grouped together to repeatedly transmit the same first indication information.

[0461] The first indication information indicating the transmission content on the second transmission resource can also be understood as the sequence carrying the first indication information indicating the transmission content on the second transmission resource.

[0462] For example, the 2 first transmission resources in the same group repeatedly transmit sequence 0, and sequence 0 is used to indicate that the second transmission resource transmits DCI, i.e., the first indication information transmitted on the first transmission resources corresponding to index 0 and index 1 is used to indicate that the second transmission resource transmits DCI.

[0463] Taking a transmission parameter corresponding to the transmission content on the second transmission resource as an example.

[0464] For example, in combination with reference to FIG. 19, the network device configures two first transmission resources and one second transmission resource, that is, one second transmission resource is associated with two first transmission resources. The two first transmission resources are used to transmit a sequence carrying first indication information. The sequence transmitted on the two first transmission resources is sequence 1. The index information corresponding to the two first transmission resources from left to right is index 0 and index 1 respectively. Optionally, the two first transmission resources are grouped, and are used to repeatedly transmit the same first indication information.

[0465] Based on the first indication information indicating the transmission parameter corresponding to the transmission content on the second transmission resource, it can be understood that, based on the sequence carrying the first indication information indicating the transmission parameter corresponding to the transmission content on the second transmission resource.

[0466] For example, the two first transmission resources in the group repeatedly transmit sequence 1, and sequence 1 is used to indicate the first DCI format transmitted on the second transmission resource, that is, the first indication information transmitted on the first transmission resources corresponding to index 0 and index 1 is used to indicate that the DCI transmitted on the second transmission resource corresponds to the first DCI format. For another example, the two first transmission resources in the group repeatedly transmit sequence 0, and sequence 0 is used to indicate the second DCI format transmitted on the second transmission resource.

[0467] 2. The second information associated with the first indication information indicates a kind of transmission information on the second transmission resource

[0468] In some embodiments, at least two first transmission resources are used to repeatedly transmit first indication information, and the second information associated with the first indication information indicates a kind of transmission information on the second transmission resource. The second information associated with the first indication information includes at least one of a time domain resource corresponding to the first indication information, a frequency domain resource corresponding to the first indication information, and a first parameter corresponding to a sequence carrying the first indication information. The first parameter includes at least one of an initial value corresponding to the sequence, a cyclic shift value corresponding to the sequence, a group number corresponding to the sequence, an intra-group root sequence number corresponding to the sequence, a sequence length corresponding to the sequence, and a sequence index corresponding to the sequence.

[0469] In some embodiments, the second information can be considered to have eight kinds, that is, the second information includes at least one of a time domain resource corresponding to the first indication information, a frequency domain resource corresponding to the first indication information, an initial value corresponding to the sequence, a cyclic shift value corresponding to the sequence, a group number corresponding to the sequence, an intra-group root sequence number corresponding to the sequence, a sequence length corresponding to the sequence, and a sequence index corresponding to the sequence.

[0470] In some embodiments, the transmission information includes any one of the DCI or the downlink data transmission in the second transmission resource, the transmission content in the second transmission resource, the transmission parameter corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0471] The following mainly takes the transmission information as the transmission content in the second transmission resource as an example.

[0472] 1) Take the first indication information corresponding to the time domain resource to indicate one kind of transmission information on the second transmission resource as an example

[0473] In some embodiments, the time domain resources corresponding to the at least two groups of first transmission resources are different. Optionally, the time domain resources corresponding to the at least two first transmission resources in the same group are different, and each of the different time domain resources can be used to indicate the transmission information on the second transmission resource.

[0474] For example, in combination with reference to FIG. 20, the network device configures four first transmission resources and one second transmission resource corresponding to each other, that is, one second transmission resource is associated with four first transmission resources. As shown in part (a) of FIG. 20, the index information corresponding to the four first transmission resources from left to right is index 0, index 1, index 2, and index 3, respectively. Optionally, the four first transmission resources are divided into two groups, and each group includes two first transmission resources. The time domain resources corresponding to each group are different. For example, the index information corresponding to the two first transmission resources in the first group is index 0 and index 1, respectively, and the index information corresponding to the two first transmission resources in the second group is index 2 and index 3, respectively. The two first transmission resources in each group are used for repeated transmission of the same first indication information. Optionally, only two first transmission resources on one group are transmitted in one repeated transmission. In one repeated transmission process, the two first transmission resources in the first group are repeatedly transmitted, and the two first transmission resources in the second group are not used. In another repeated transmission process, the two first transmission resources in the first group are not used, and the two first transmission resources in the second group are repeatedly transmitted, that is, the two first transmission resources on the first group and the two first transmission resources on the second group are transmitted separately.

[0475] In the above example, the time domain resources of the first group and the second group are different, which can also be understood as the time domain resources corresponding to the two first transmission resources in the first group are different from the time domain resources corresponding to the two first transmission resources in the second group.

[0476] The second information associated with the first indication information indicates one kind of transmission information in the second transmission resource, for example, the transmission content in the second transmission resource based on the time domain resource corresponding to the first indication information.

[0477] For example, the time domain resources corresponding to the 2 first transmission resources in the first group indicate no transmission on the second transmission resources, i.e., the time domain resources corresponding to the first transmission resources with index 0 and index 1 are used to indicate no transmission on the second transmission resources.

[0478] In some embodiments, the at least two first transmission resources on the same group can be adjacent first transmission resources or non-adjacent first transmission resources. The present application does not limit this.

[0479] 2) Take an example of the frequency domain resources corresponding to the first indication information indicating a kind of transmission information on the second transmission resources

[0480] In some embodiments, the frequency domain resources corresponding to the at least two groups of first transmission resources are different. Optionally, the frequency domain resources corresponding to the at least two first transmission resources on the same group are different, and each of the different frequency domain resources can be used to indicate the transmission information on the second transmission resources.

[0481] For example, in combination with reference to FIG. 20, the network device configures 4 first transmission resources and one second transmission resource corresponding to each other, i.e., one second transmission resource is associated with 4 first transmission resources. As shown in part (b) of FIG. 20, the index information corresponding to the 4 first transmission resources from bottom to top is index 0, index 1, index 2 and index 3, respectively. Optionally, the 4 first transmission resources are divided into two groups, and each group includes 2 first transmission resources. In one repeated transmission process, the 2 first transmission resources in the first group are repeatedly transmitted, and the 2 first transmission resources in the second group are not used. In another repeated transmission process, the 2 first transmission resources in the first group are not used, and the 2 first transmission resources in the second group are repeatedly transmitted, i.e., the 2 first transmission resources on the first group and the 2 first transmission resources on the second group are transmitted separately.

[0482] In the above example, the frequency domain resources of the first group and the second group are different, which can also be understood as the frequency domain resources corresponding to the 2 first transmission resources in the first group are different from the frequency domain resources corresponding to the 2 first transmission resources in the second group.

[0483] The second information associated based on the first indication information indicates a kind of transmission information on the second transmission resources, for example, the frequency domain resources corresponding to the first indication information indicate the transmission content on the second transmission resources.

[0484] For example, the frequency domain resources corresponding to the 2 first transmission resources in the first group indicate no transmission on the second transmission resources, i.e., the frequency domain resources corresponding to the first transmission resources with index 0 and index 1 are used to indicate no transmission on the second transmission resources. For example, the frequency domain resources of the 2 first transmission resources in the second group are used to indicate transmission of DCI on the second transmission resources, i.e., the frequency domain resources corresponding to the first transmission resources with index 2 and index 3 are used to indicate transmission of DCI on the second transmission resources.

[0485] In some embodiments, the at least two first transmission resources on the same group can be adjacent first transmission resources or non-adjacent first transmission resources. The present application does not limit this.

[0486] 3) Take the combination of the time domain resources and the frequency domain resources corresponding to the first indication information as an example

[0487] In some embodiments, a part of the second information associated with the first indication information is used to indicate a kind of transmission information on the second transmission resources. Wherein, the part of the second information can be understood as at least one second information. For example, the part of the second information includes the time domain resources corresponding to the first indication information and the frequency domain resources corresponding to the first indication information. Alternatively, the combination of the time domain resources and the frequency domain resources corresponding to the first indication information is used to indicate a kind of transmission information on the second transmission resources.

[0488] For example, in combination with reference to FIG. 20, the network device configures 4 first transmission resources corresponding to one second transmission resource, i.e., one second transmission resource is associated with 4 first transmission resources. The combination of the time domain resources and the frequency domain resources corresponding to the first indication information is used to indicate the transmission content in the second transmission resources. As shown in part (c) of FIG. 20, the 4 first transmission resources are in the order of frequency domain first and time domain second, and the corresponding index information is index 0, index 1, index 2 and index 3 respectively.

[0489] When the combination of the time domain resources and the frequency domain resources corresponding to the first indication information is used to indicate the transmission content in the second transmission resources, different groups can be represented based on group numbers. Alternatively, the 4 first transmission resources are divided into two groups, and each group includes 2 first transmission resources. For example, group number 1 represents the first group, and the index information corresponding to the 2 first transmission resources in the first group is index 0 and index 3 respectively; group number 2 represents the second group, and the index information corresponding to the 2 first transmission resources in the second group is index 1 and index 2 respectively.

[0490] Wherein, the time domain resources and the frequency domain resources of the group number 1 (the first group) and the group number 2 (the second group) are different. It can also be understood that the time domain resources and the frequency domain resources corresponding to the 2 first transmission resources in the first group are different from the time domain resources and the frequency domain resources corresponding to the 2 first transmission resources in the second group.

[0491] For example, as shown in the (c) part of FIG. 20, the time domain resource and the frequency domain resource corresponding to the 2 first transmission resources in the group number 1 (the first group) are used to indicate no transmission on the second transmission resource, i.e., the time domain resource and the frequency domain resource with index 0 and index 3 are used to indicate no transmission on the second transmission resource. For example, the time domain resource and the frequency domain resource corresponding to the 2 first transmission resources in the group number 2 (the second group) are used to indicate transmission of DCI on the second transmission resource, i.e., the time domain resource and the frequency domain resource corresponding to the first transmission resource with index 1 and index 2 are used to indicate transmission of DCI on the second transmission resource.

[0492] The 2 first transmission resources in each group are respectively used to repeatedly transmit the same first indication information. In one repetition transmission process, the 2 first transmission resources in the first group are repeatedly transmitted, and the 2 first transmission resources in the second group are not used; in another repetition transmission process, the 2 first transmission resources in the first group are not used, and the 2 first transmission resources in the second group are repeatedly transmitted, i.e., the 2 first transmission resources on the first group and the 2 first transmission resources on the second group are separately transmitted.

[0493] In some embodiments, the at least two first transmission resources on the same group can be adjacent first transmission resources, or can be non-adjacent first transmission resources. The present application does not make any limitation in this regard.

[0494] Scenario two: based on the first indication information and / or the second information associated with the first indication information to indicate at least two transmission information on the second transmission resource

[0495] In some embodiments, the first transmission resource and the second transmission resource include a many-to-one relationship, i.e., a plurality of first transmission resources correspond to one second transmission resource, or it can be understood that one second transmission resource is associated with a plurality of first transmission resources.

[0496] In some embodiments, the network device configures at least two first transmission resources for repeatedly transmitting the first indication information, and the first indication information is used to indicate the transmission content on the second transmission resource. The at least two first transmission resources are all or part of a plurality of first transmission resources. Optionally, the plurality of first transmission resources are divided into at least two groups, and the at least two first transmission resources are a group of first transmission resources in the at least two groups. Wherein, the time domain resource and / or the frequency domain resource of different groups are different, which can be understood as the time domain resource and / or the frequency domain resource corresponding to the first transmission resources on different groups are different.

[0497] In some embodiments, the first indication information and / or the second information associated with the first indication information indicates at least two kinds of transmission information on the second transmission resource. Each kind of transmission information is indicated by one information or combination of information in the first indication information and the at least one second information, and different transmission information is indicated by different information or combination of information in the first indication information and the at least one second information. Alternatively, the first indication information and / or the second information associated with the first indication information indicates at least two kinds of transmission information on the second transmission resource. The at least two kinds of transmission information include at least two of the following: whether there is DCI or downlink data transmission in the second transmission resource, the transmission content in the second transmission resource, the transmission parameter corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0498] When the number of kinds of transmission information on the second transmission resource is different, at least two kinds of transmission information can be indicated by different combination of the first indication information and / or the second information associated with the first indication information.

[0499] 1. The transmission information on the second transmission resource is two kinds

[0500] In some embodiments, the first indication information and / or the second information associated with the first indication information indicates two kinds of transmission information on the second transmission resource. The two kinds of transmission information include any two of the following: whether there is DCI or downlink data transmission in the second transmission resource, the transmission content in the second transmission resource, the transmission parameter corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0501] In some embodiments, the first indication information and / or the second information associated with the first indication information indicates two kinds of transmission information on the second transmission resource. It can also be understood that the first indication information and / or the second information associated with the first indication information jointly indicates two kinds of transmission information on the second transmission resource. It can also be understood that the first indication information and / or the second information associated with the first indication information jointly indicates two kinds of transmission information on the second transmission resource.

[0502] The two kinds of transmission information on the second transmission resource can be any two kinds of different transmission information.

[0503] Exemplarily, the two kinds of transmission information included in the transmission information are: whether there is DCI or downlink data transmission in the second transmission resource, and the transmission content in the second transmission resource. Exemplarily, the two kinds of transmission information included in the transmission information are: whether there is DCI or downlink data transmission in the second transmission resource, and the transmission parameter corresponding to the transmission content in the second transmission resource. Exemplarily, the two kinds of transmission information included in the transmission information are: whether there is DCI or downlink data transmission in the second transmission resource, and the resource location of the transmission resource in the second transmission resource. Exemplarily, the two kinds of transmission information included in the transmission information are: the transmission content in the second transmission resource and the transmission parameter corresponding to the transmission content. Exemplarily, the two kinds of transmission information included in the transmission information are: the transmission content in the second transmission resource and the resource location of the transmission resource in the second transmission resource. Exemplarily, the two kinds of transmission information included in the transmission information are: the transmission parameter corresponding to the transmission content in the second transmission resource and the resource location of the transmission resource in the second transmission resource.

[0504] In some embodiments, the plurality of first transmission resources are divided into M groups. Each of the M groups includes at least two first transmission resources. Optionally, the M groups of first transmission resources are used for repeatedly transmitting the first indication information and / or the second information associated with the first indication information, and the repeatedly transmitted first indication information and / or the second information associated with the first indication information are used for indicating the two kinds of transmission information on the second transmission resource. M is a positive integer greater than 2.

[0505] In some embodiments, the network device configures N first transmission resources corresponding to the second transmission resource for the terminal device, i.e., the second transmission resource is associated with the N first transmission resources, and N is a positive integer greater than 1. Optionally, the index information corresponding to the N first transmission resources are 0, 1, 2, 3, …, N-1, respectively.

[0506] In some embodiments, when the transmission information on the second transmission resource is two kinds, the two kinds of transmission information on the second transmission resource are indicated based on the repeatedly transmitted first indication information and / or the second information associated with the first indication information. Optionally, the two kinds of transmission information on the second transmission resource are indicated based on the repeatedly transmitted first indication information; or the two kinds of transmission information on the second transmission resource are indicated based on the second information associated with the first indication information; or the two kinds of transmission information on the second transmission resource are indicated based on the repeatedly transmitted first indication information and the second information associated with the first indication information.

[0507] The first indication information and / or the second information associated with the first indication information indicating the two kinds of transmission information on the second transmission resource include, but are not limited to, at least one of the following indication manners:

[0508] • The first indication information is used for indicating the first kind of transmission information and the second kind of transmission information;

[0509] • The first indication information is used to indicate the first kind of transmission information, and at least part of the second information associated with the first indication information is used to indicate the second kind of transmission information.

[0510] • The first part of the second information associated with the first indication information is used to indicate the first kind of transmission information, and the second part of the second information associated with the first indication information is used to indicate the second kind of transmission information.

[0512] • The combination of the first indication information and the first part of the second information associated with the first indication information is used to indicate the first kind of transmission information, and the second part of the second information associated with the first indication information is used to indicate the second kind of transmission information.

[0513] It should be noted that the first part of the second information and the second part of the second information include at least one of the eight kinds of second information. Any two parts of the first part of the second information and the second part of the second information are different or not completely the same. This application does not limit this.

[0514] Hereinafter, part of the second information can be considered as the first part of the second information, and the other part of the second information can be considered as the second part of the second information.

[0515] Some examples are given below, but all possible combinations cannot be exhausted, and the following examples are only illustrative.

[0516] 1) The first indication information is used to indicate the first kind of transmission information and the second kind of transmission information

[0517] In some embodiments, the first indication information is based on a sequence. Based on the first indication information indicating two kinds of transmission information on the second transmission resource, it can also be understood as based on the sequence indicating two kinds of transmission information on the second transmission resource, or understood as based on the sequence carrying the first indication information indicating two kinds of transmission information on the second transmission resource.

[0518] In some embodiments, when indicating two groups of transmission information on the second transmission resource based on the first indication information, different kinds of transmission information are indicated based on different first indication information, i.e., different kinds of transmission information are indicated based on different sequences carrying the first indication information. For example, the first sequence is used to indicate the first kind of transmission information, and the second sequence is used to indicate the second kind of transmission information.

[0519] For example, referring to FIG. 21, taking the transmission content on the second transmission resource and the transmission parameter corresponding to the transmission content as an example, the network device configures four first transmission resources and one second transmission resource, that is, one second transmission resource is associated with four first transmission resources. The four first transmission resources are used to transmit the sequence carrying the first indication information. Optionally, the four first transmission resources are divided into a group.

[0520] The first indication information based on the repeated transmission indicates the transmission content and the transmission parameter corresponding to the transmission content.

[0521] As shown in part (a) of FIG. 21, when the four first transmission resources in the group repeatedly transmit sequence 0, the first indication information on the sequence 0 is used to indicate that the DCI is transmitted on the second transmission resource and the DCI is the first DCI format. As shown in part (b) of FIG. 21, when the four first transmission resources in the group repeatedly transmit sequence 1, the first indication information on the sequence 1 is used to indicate that the downlink data is transmitted on the second transmission resource and adopts QPSK modulation.

[0522] 2) The first indication information is used to indicate the first kind of transmission information, and a part of the second information associated with the first indication information is used to indicate the second kind of transmission information

[0523] In some embodiments, the transmission information on the second transmission resource is two kinds, and each kind of transmission information is indicated by the combination of the first indication information and the information in a part of the second information. The first indication information based on the repeated transmission and the second information associated with the first indication information jointly indicate the two kinds of transmission information. Optionally, the first indication information is used to indicate the first kind of transmission information, and a part of the second information associated with the first indication information is used to indicate the second kind of transmission information. In some embodiments, the part of the second information associated with the first indication information can also be understood as at least one kind of second information associated with the first indication information.

[0524] In some embodiments, the second information can be considered to have eight kinds, that is, the second information includes at least one of the time domain resource corresponding to the first indication information, the frequency domain resource corresponding to the first indication information, the initial value corresponding to the sequence, the cyclic shift value corresponding to the sequence, the group number corresponding to the sequence, the root sequence number in the group corresponding to the sequence, the sequence length corresponding to the sequence, and the sequence index corresponding to the sequence.

[0525] In some embodiments, the first indication information is used to indicate the first kind of transmission information, and a part of the second information associated with the first indication information is used to indicate the second kind of transmission information; it can also be understood that the first indication information is used to indicate the first kind of transmission information, and at least one kind of second information associated with the first indication information is used to indicate the second kind of transmission information.

[0526] For example, the first indication information is used to indicate the transmission content on the second transmission resource (e.g., the DCI is transmitted on the second transmission resource), and the time domain resource corresponding to the first indication information is used to indicate the transmission parameter corresponding to the transmission content on the second transmission resource (e.g., the aggregation level of the DCI). For another example, the first indication information is used to indicate the transmission content on the second transmission resource (e.g., the downlink data is transmitted on the second transmission resource), and the frequency domain resource corresponding to the first indication information is used to indicate the resource location of the transmission resource corresponding to the transmission content on the second transmission resource (e.g., the frequency domain starting location of the transmission resource corresponding to the downlink data on the second transmission resource).

[0527] For example, in combination with reference to FIG. 22, the transmission content on the second transmission resource and the transmission parameter corresponding to the transmission content are taken as examples for illustration. The network device configures four first transmission resources and one second transmission resource corresponding to each other, that is, one second transmission resource is associated with four first transmission resources. The index information corresponding to the four first transmission resources from left to right is index 0, index 1, index 2, and index 3, respectively. Optionally, the four first transmission resources are divided into two groups, and each group includes two first transmission resources. For example, the index information corresponding to the two first transmission resources in the first group is index 0 and index 1, respectively, and the index information corresponding to the two first transmission resources in the second group is index 2 and index 3, respectively.

[0528] In this case, the time domain resources of the first group and the second group are different, and it can also be understood that the time domain resources corresponding to the two first transmission resources in the first group are different from the time domain resources corresponding to the two first transmission resources in the second group.

[0529] The first indication information based on the repeated transmission and the second information associated with the first indication information jointly indicate the transmission content and the transmission parameter corresponding to the transmission content. Optionally, the first indication information is used to indicate the transmission content, and a part of the second information (e.g., the time domain resource) associated with the first indication information is used to indicate the transmission parameter corresponding to the transmission content. For example, when the sequence is 0, the sequence transmitted on the first transmission resource corresponding to index 0 to index 3 indicates that the DCI is transmitted on the second transmission resource.

[0530] As shown in FIG. 22, the sequence of the transmission on the four first transmission resources is sequence 0, and sequence 0 is used to indicate the DCI transmitted on the second transmission resource. The four first transmission resources are divided into two groups, and the time domain resources corresponding to the two first transmission resources on each group are used to indicate the aggregation level corresponding to the DCI transmitted on the second transmission resource. For example, in the current repeated transmission process, the time domain resources corresponding to the two first transmission resources in the first group are used to indicate that the aggregation level corresponding to the DCI transmitted on the second transmission resource is 1, that is, the time domain resources corresponding to the first transmission resources with indexes 0 and 1 are used to indicate that the aggregation level corresponding to the DCI transmitted on the second transmission resource is 1. For example, in another repeated transmission process, the time domain resources corresponding to the two first transmission resources in the second group are used to indicate that the aggregation level corresponding to the DCI transmitted on the second transmission resource is 2, that is, the time domain resources corresponding to the first transmission resources with indexes 2 and 3 are used to indicate that the aggregation level corresponding to the DCI transmitted on the second transmission resource is 2.

[0531] 3) The first part of the second information associated with the first indication information is used to indicate the first kind of transmission information, and the second part of the second information associated with the first indication information is used to indicate the second kind of transmission information

[0532] In the above embodiments, the first part of the second information is a part of the second information, and the second part of the second information is another part of the second information. Any two parts of the second information in the first part of the second information and the second part of the second information are different or not completely the same. Hereinafter, a part of the second information can be regarded as the first part of the second information, and another part of the second information can be regarded as the second part of the second information.

[0533] In some embodiments, the transmission information on the second transmission resource is two kinds, and the second information associated with the first indication information based on the repeated transmission indicates the two kinds of transmission information. Alternatively, a part of the second information associated with the first indication information is used to indicate the first kind of transmission information, and another part of the second information associated with the first indication information is used to indicate the second kind of transmission information. In some embodiments, a part of the second information associated with the first indication information can also be understood as at least one kind of second information associated with the first indication information.

[0534] In some embodiments, the second information can be considered to have eight kinds, that is, the second information includes at least one of the time domain resource corresponding to the first indication information, the frequency domain resource corresponding to the first indication information, the initial value corresponding to the sequence, the cyclic shift value corresponding to the sequence, the group number corresponding to the sequence, the intra-group root sequence number corresponding to the sequence, the sequence length corresponding to the sequence, and the sequence index corresponding to the sequence.

[0535] In some embodiments, a part of the second information associated with the first indication information is used to indicate the first kind of transmission information, and another part of the second information associated with the first indication information is used to indicate the second kind of transmission information. Alternatively, one kind of the second information associated with the first indication information is used to indicate the first kind of transmission information, and another kind of the second information associated with the first indication information is used to indicate the second kind of transmission information.

[0536] For example, the time domain resource corresponding to the first indication information is used to indicate the transmission content on the second transmission resource (e.g., DCI is transmitted on the second transmission resource), and the frequency domain resource corresponding to the first indication information is used to indicate the transmission parameter corresponding to the transmission content on the second transmission resource (e.g., the aggregation level of the DCI). For another example, the time domain resource corresponding to the first indication information is used to indicate the transmission content on the second transmission resource (e.g., downlink data is transmitted on the second transmission resource), and the sequence parameter corresponding to the sequence carrying the first indication information is used to indicate the transmission parameter corresponding to the transmission content on the second transmission resource (the transport block size TBS corresponding to the downlink data).

[0537] For example, in combination with reference to FIG. 23, taking the transmission content on the second transmission resource and the transmission parameter corresponding to the transmission content as an example, the network device configures four first transmission resources and one second transmission resource corresponding to each other, that is, one second transmission resource is associated with four first transmission resources. The index information corresponding to the four first transmission resources from left to right is index 0, index 1, index 2, and index 3, respectively. Optionally, the four first transmission resources are divided into two groups, and each group includes two first transmission resources. For example, the index information corresponding to the two first transmission resources in the first group is index 0 and index 1, respectively, and the index information corresponding to the two first transmission resources in the second group is index 2 and index 3, respectively. Optionally, the sequence length corresponding to the sequence transmitted by the first transmission resource in each group is the same.

[0538] Among them, the time domain resources of the first group and the second group are different, and the sequence length of the first group and the second group is different.

[0539] For example, in combination with reference to FIG. 23, taking the transmission content on the second transmission resource and the transmission parameter corresponding to the transmission content as an example, the network device configures four first transmission resources and one second transmission resource corresponding to each other, that is, one second transmission resource is associated with four first transmission resources. The index information corresponding to the four first transmission resources from left to right is index 0, index 1, index 2, and index 3, respectively. Optionally, the four first transmission resources are divided into two groups, and each group includes two first transmission resources. For example, the index information corresponding to the two first transmission resources in the first group is index 0 and index 1, respectively, and the index information corresponding to the two first transmission resources in the second group is index 2 and index 3, respectively. Optionally, the sequence length corresponding to the sequence transmitted by the first transmission resource in each group is the same.

[0540] As shown in the (a) part of Figure 23, the 4 first transmission resources are divided into two groups, the time domain resources of the first group and the second group are different, and the time domain resources corresponding to the first transmission resources are used to indicate the transmission content on the second transmission resources. For example, the time domain resources corresponding to the 2 first transmission resources in the first group are used to indicate that the DCI is transmitted on the second transmission resources, and the sequences transmitted by the 2 first transmission resources in the first group correspond to a sequence length of a first length, and the first length is used to indicate that the format corresponding to the DCI on the second transmission resources is a first DCI format, that is, the time domain resources corresponding to the first transmission resources with index 0 and index 1 are used to indicate that the DCI is transmitted on the second transmission resources, and the first length indicates that the format corresponding to the DCI is the first DCI format. For example, the time domain resources corresponding to the 2 first transmission resources in the second group are used to indicate that the downlink data is transmitted on the second transmission resources, and the sequences transmitted by the 2 first transmission resources in the first group correspond to a sequence length of a first length, and the first length is used to indicate that the modulation mode of the downlink data transmitted on the second transmission resources is QPSK, that is, the time domain resources corresponding to the first transmission resources with index 2 and index 3 are used to indicate that the downlink data is transmitted on the second transmission resources, and the first length indicates that the modulation mode of the transmitted downlink data is QPSK.

[0541] As shown in the (b) part of Figure 23, the 4 first transmission resources are divided into two groups, the time domain resources of the first group and the second group are different, and the time domain resources corresponding to the first transmission resources are used to indicate the transmission content on the second transmission resources. For example, the time domain resources corresponding to the 2 first transmission resources in the first group are used to indicate that the DCI is transmitted on the second transmission resources, and the sequences transmitted by the 2 first transmission resources in the first group correspond to a sequence length of a second length, and the second length is used to indicate that the format corresponding to the DCI on the second transmission resources is a second DCI format, that is, the time domain resources corresponding to the first transmission resources with index 0 and index 1 are used to indicate that the DCI is transmitted on the second transmission resources, and the second length indicates that the format corresponding to the DCI is the second DCI format. For example, the time domain resources corresponding to the 2 first transmission resources in the second group are used to indicate that the downlink data is transmitted on the second transmission resources, and the sequences transmitted by the 2 first transmission resources in the second group correspond to a sequence length of a second length, and the second length is used to indicate that the modulation mode of the downlink data transmitted on the second transmission resources is 16QAM, that is, the time domain resources corresponding to the first transmission resources with index 2 and index 3 are used to indicate that the downlink data is transmitted on the second transmission resources, and the second length indicates that the modulation mode of the transmitted downlink data is 16QAM.

[0542] 4) The combination of the first indication information and the part of the second information associated with the first indication information is used to indicate the first kind of transmission information, and the first indication information is used to indicate the second kind of transmission information

[0543] In some embodiments, the transmission information on the second transmission resource is two kinds. The first indication information based on repeated transmission and the second information associated with the first indication information jointly indicate the two kinds of transmission information. Alternatively, the information combination of the first indication information and a part of the second information associated with the first indication information is used to indicate the first kind of transmission information, and the first indication information is used to indicate the second kind of transmission information. In some embodiments, the part of the second information associated with the first indication information can also be understood as at least one kind of second information associated with the first indication information.

[0544] In some embodiments, the first indication information and a part of the second information associated with the first indication information are used to indicate the second kind of transmission information, and the first indication information is used to indicate the second kind of transmission information. It can also be understood that the first indication information and at least one kind of second information associated with the first indication information are used to indicate the first kind of transmission information, and the first indication information is used to indicate the second kind of transmission information. In some embodiments, the first indication information is carried based on a sequence.

[0545] For example, the first indication information and the sequence length combination corresponding to the sequence carrying the first indication information indicate the transmission content on the second transmission resource, and the first indication information is used to indicate the transmission parameter corresponding to the transmission content on the second transmission resource. For another example, the first indication information, the time domain resource corresponding to the first indication information, and the cyclic shift value corresponding to the sequence carrying the first indication information are combined to indicate the transmission parameter corresponding to the transmission content in the second transmission resource, and the first indication information is used to indicate the resource location of the transmission resource corresponding to the transmission content in the second transmission resource.

[0546] For example, the first indication information and the sequence length combination corresponding to the sequence carrying the first indication information indicate the transmission content on the second transmission resource, and the first indication information is used to indicate the transmission parameter corresponding to the transmission content on the second transmission resource. For another example, the first indication information, the time domain resource corresponding to the first indication information, and the cyclic shift value corresponding to the sequence carrying the first indication information are combined to indicate the transmission parameter corresponding to the transmission content in the second transmission resource, and the first indication information is used to indicate the resource location of the transmission resource corresponding to the transmission content in the second transmission resource.

[0547] The first indication information is used to indicate the transmission content, and the combination of the first indication information and the part of the second information (such as time domain resources) associated with the first indication information is used to indicate the transmission parameter corresponding to the transmission content. For example, when the sequence is 0, the first transmission resources corresponding to the indexes 0 to 3 transmit the sequence indicating that the DCI is transmitted on the second transmission resources, and when the sequence is 1, the first transmission resources corresponding to the indexes 0 to 3 transmit the sequence indicating that the downlink data is transmitted on the second transmission resources.

[0548] As shown in the (a) part of FIG. 24, the sequence transmitted on the 4 first transmission resources is sequence 0, and the sequence 0 is used to indicate that the DCI is transmitted on the second transmission resources. The 4 first transmission resources are divided into two groups, and the time domain resources corresponding to the sequence and the first transmission resources are used to jointly indicate the DCI format corresponding to the DCI transmitted on the second transmission resources. For example, in the current repeated transmission process, the time domain resources corresponding to the sequence 0 and the 2 first transmission resources in the first group are used to indicate that the DCI format corresponding to the DCI on the second transmission resources is the first DCI format, that is, when the sequence is 0, the time domain resources corresponding to the first transmission resources with indexes 0 and 1 are used to indicate that the DCI format corresponding to the DCI on the second transmission resources is the first DCI format. For example, in another repeated transmission process, the time domain resources corresponding to the sequence 0 and the 2 first transmission resources in the second group are used to indicate that the DCI format corresponding to the DCI on the second transmission resources is the second DCI format, that is, when the sequence is 0, the time domain resources corresponding to the first transmission resources with indexes 2 and 3 are used to indicate that the DCI format corresponding to the DCI on the second transmission resources is the second DCI format.

[0549] As shown in the (b) part of FIG. 24, the sequence transmitted on the 4 first transmission resources is sequence 1, and the sequence 1 is used to indicate that the downlink data is transmitted on the second transmission resources. The 4 first transmission resources are divided into two groups, and the time domain resources corresponding to the sequence and the first transmission resources are used to indicate the modulation mode of the downlink data transmitted on the second transmission resources. For example, in the current repeated transmission process, the time domain resources corresponding to the sequence 1 and the 2 first transmission resources in the first group are used to indicate that the modulation mode corresponding to the downlink data on the second transmission resources is the QPSK modulation mode, that is, when the sequence is 1, the first indication information transmitted on the first transmission resources with indexes 0 and 1 is used to indicate that the modulation mode corresponding to the downlink data on the second transmission resources is the 16QAM modulation mode. For example, in another repeated transmission process, the time domain resources corresponding to the sequence 1 and the 2 first transmission resources in the second group are used to indicate that the modulation mode corresponding to the downlink data on the second transmission resources is the 16QAM modulation mode, that is, when the sequence is 1, the time domain resources corresponding to the first transmission resources with indexes 2 and 3 are used to indicate that the modulation mode corresponding to the downlink data on the second transmission resources is the QPSK modulation mode.

[0550] 5) the combination of the first indication information and a part of the second information associated with the first indication information is used to indicate the first kind of transmission information, and another part of the second information associated with the first indication information is used to indicate the second kind of transmission information

[0551] In some embodiments, the transmission information on the second transmission resource is two kinds. The first indication information based on repetition transmission and the second information associated with the first indication information jointly indicate the two kinds of transmission information. Alternatively, the combination of the first indication information and a part of the second information associated with the first indication information is used to indicate the first kind of transmission information, and another part of the second information associated with the first indication information is used to indicate the second kind of transmission information. In some embodiments, the part of the second information associated with the first indication information can also be understood as at least one kind of second information associated with the first indication information.

[0552] In some embodiments, the combination of the first indication information and a part of the second information associated with the first indication information is used to indicate the first kind of transmission information, and another part of the second information associated with the first indication information is used to indicate the second kind of transmission information. Alternatively, the first indication information and one kind of second information associated with the first indication information are used to indicate the first kind of transmission information, and another kind of second information associated with the first indication information is used to indicate the second kind of transmission information. In some embodiments, the first indication information is carried based on a sequence.

[0553] For example, the combination of the first indication information and the time domain resource corresponding to the first indication information indicates the transmission content on the second transmission resource, and the frequency domain resource corresponding to the first indication information is used to indicate the transmission parameter corresponding to the transmission content on the second transmission resource. For another example, the combination of the first indication information and the sequence length corresponding to the sequence carrying the first indication information indicates the transmission parameter corresponding to the transmission content in the second transmission resource, and the cyclic shift value corresponding to the sequence carrying the first indication information is used to indicate the resource location of the transmission resource corresponding to the transmission content in the second transmission resource.

[0554] 2. The transmission information on the second transmission resource is three kinds

[0555] In some embodiments, the first indication information based on repetition transmission and / or the second information associated with the first indication information jointly indicate the three kinds of transmission information on the second transmission resource. The three kinds of transmission information include any three of the DCI or downlink data transmission in the second transmission resource, the transmission content in the second transmission resource, the transmission parameter corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0556] In some embodiments, the first indication information and / or the second information associated with the first indication information jointly indicates the three transmission information on the second transmission resource. In some embodiments, the first indication information and / or the second information associated with the first indication information jointly indicates the three transmission information on the second transmission resource. In some embodiments, the first indication information and / or the second information associated with the first indication information jointly indicates the three transmission information on the second transmission resource.

[0557] For example, the three transmission information includes: whether there is DCI or downlink data transmission in the second transmission resource, the transmission content in the second transmission resource, and the transmission parameter corresponding to the transmission content in the second transmission resource. For example, the three transmission information includes: whether there is DCI or downlink data transmission in the second transmission resource, the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource. For example, the three transmission information includes: whether there is DCI or downlink data transmission in the second transmission resource, the transmission parameter corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource. For example, the three transmission information includes: the transmission content in the second transmission resource, the transmission parameter corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0558] In some embodiments, the plurality of first transmission resources are divided into M groups. Each of the M groups includes at least two first transmission resources. Optionally, the M groups of first transmission resources are used for repeated transmission of the first indication information and / or the second information associated with the first indication information, and the repeated transmission of the first indication information and / or the second information associated with the first indication information is used to indicate the three transmission information on the second transmission resource. M is a positive integer greater than 2.

[0559] In some embodiments, the network device configures N first transmission resources corresponding to the second transmission resource for the terminal device, i.e., the second transmission resource is associated with N first transmission resources, and N is a positive integer greater than 1. Optionally, the index information corresponding to the N first transmission resources are 0, 1, 2, 3, …, N-1, respectively.

[0560] In some embodiments, when the transmission information on the second transmission resource is three, the first indication information and / or the second information associated with the first indication information based on repeated transmission indicates the three transmission information on the second transmission resource. Optionally, the first indication information based on repeated transmission indicates the three transmission information on the second transmission resource; or the second information associated with the first indication information based on repeated transmission indicates the three transmission information on the second transmission resource; or the first indication information and the second information associated with the first indication information based on repeated transmission jointly indicates the three transmission information on the second transmission resource.

[0561] The first indication information and / or the second information associated with the first indication information indicates three kinds of transmission information on the second transmission resource, including but not limited to at least one of the following indication manners:

[0562] The first indication information is used to indicate the first kind of transmission information, the second kind of transmission information and the third kind of transmission information.

[0563] The first indication information is used to indicate the first kind of transmission information and the second kind of transmission information, and a part of the second information associated with the first indication information is used to indicate the third kind of transmission information.

[0564] The first indication information is used to indicate the first kind of transmission information, a first part of the second information associated with the first indication information is used to indicate the second kind of transmission information, and a second part of the second information associated with the first indication information is used to indicate the third kind of transmission information.

[0565] A first part of the second information associated with the first indication information is used to indicate the first kind of transmission information, a second part of the second information associated with the first indication information is used to indicate the second kind of transmission information, and a third part of the second information associated with the first indication information is used to indicate the third kind of transmission information.

[0566] The first indication information is used to indicate the first kind of transmission information, a part of the second information associated with the first indication information is used to indicate the second kind of transmission information, and the information combination of the first indication information and the part of the second information associated with the first indication information is used to indicate the third kind of transmission information.

[0567] The first indication information is used to indicate the first kind of transmission information, the information combination of the first indication information and a first part of the second information associated with the first indication information is used to indicate the second kind of transmission information, and a second part of the second information associated with the first indication information is used to indicate the third kind of transmission information.

[0568] A first part of the second information associated with the first indication information is used to indicate the first kind of transmission information, the information combination of the first indication information and the first part of the second information associated with the first indication information is used to indicate the second kind of transmission information, and a second part of the second information associated with the first indication information is used to indicate the third kind of transmission information.

[0569] It should be noted that the first part of the second information, the second part of the second information and the third part of the second information all include at least one of the eight kinds of second information. Any two parts of the first part of the second information, the second part of the second information and the third part of the second information are different or not completely the same. The present application does not limit this.

[0570] Some of the second information appearing below can be considered as the first part of the second information, another part of the second information can be considered as the second part of the second information, and another part of the second information can be considered as the third part of the second information.

[0571] Some examples are given below, but not all possible combinations can be enumerated, and the following examples are only illustrative.

[0572] 1) The first indication information is used to indicate the first kind of transmission information, the second kind of transmission information and the third kind of indication information

[0573] In some embodiments, the first indication information is based on a sequence. Based on the first indication information indicating the three kinds of transmission information on the second transmission resource, it can also be understood that the three kinds of transmission information are indicated based on a sequence, or it can also be understood that the three kinds of transmission information are indicated based on different sequences carrying the first indication information.

[0574] In some embodiments, when the three kinds of transmission information on the second transmission resource are indicated based on the first indication information, different kinds of transmission information are indicated based on different first indication information, i.e., different kinds of transmission information are indicated based on different sequences carrying the first indication information. For example, the first sequence is used to indicate the first kind of transmission information, the second sequence is used to indicate the second kind of transmission information, and the third sequence is used to indicate the third kind of transmission information.

[0575] For example, the three kinds of transmission information are the transmission content on the second transmission resource, the transmission parameter corresponding to the transmission content, and the resource location of the transmission resource in the second transmission resource. The network device configures four first transmission resources and one second transmission resource corresponding to each other, i.e., one second transmission resource is associated with four first transmission resources. The four first transmission resources are used to transmit sequences carrying the first indication information. Optionally, the four first transmission resources are divided into a group. The transmission content, the transmission parameter corresponding to the transmission content, and the resource location of the transmission resource in the second transmission resource are indicated based on the repeated transmission of the first indication information.

[0576] For example, when the four first transmission resources in a group repeatedly transmit sequence 0, the first indication information on sequence 0 is used to indicate that DCI is transmitted on the second transmission resource and the DCI is the first DCI format, and the sequence is 0, the resource location of the transmission resource corresponding to the DCI used to indicate the transmission on the second transmission resource is the time domain starting position A. For another example, when the four first transmission resources in a group repeatedly transmit sequence 1, the first indication information on sequence 1 is used to indicate that downlink data is transmitted on the second transmission resource and the modulation mode of the downlink data is QPSK modulation, and the sequence is 1, the resource location of the transmission resource corresponding to the downlink data used to indicate the transmission on the second transmission resource is the time domain starting position B.

[0577] 2) the first indication information is used to indicate the first transmission information and the second transmission information, and a part of the second information associated with the first indication information is used to indicate the third transmission information

[0578] In some embodiments, when the first indication information based on the repeated transmission and the second information associated with the first indication information jointly indicate the three transmission information on the second transmission resource, the first indication information based on the repeated transmission can be used to indicate a part of the transmission information (e.g., the first transmission information and the second transmission information), and the at least one second information associated with the first indication information can be used to indicate the remaining part of the transmission information (e.g., the third transmission information).

[0579] For example, with reference to FIG. 25, taking the three transmission information as the transmission content in the second transmission resource, the transmission parameter corresponding to the transmission content, and the resource location of the transmission resource in the second transmission resource, respectively, as an example. The network device configures four first transmission resources and one second transmission resource correspondingly, i.e., one second transmission resource is associated with four first transmission resources. The index information corresponding to the four first transmission resources from left to right is index 0, index 1, index 2, and index 3, respectively. Optionally, the four first transmission resources are divided into two groups, and each group includes two first transmission resources. For example, the index information corresponding to the two first transmission resources in the first group is index 0 and index 1, respectively, and the index information corresponding to the two first transmission resources in the second group is index 2 and index 3, respectively. Among them, the time domain resources of the first group and the second group are different.

[0580] The first indication information based on the repeated transmission and a part of the second information associated with the first indication information jointly indicate the transmission content, the transmission parameter corresponding to the transmission content, and the resource location of the transmission resource corresponding to the transmission content in the second transmission resource. Optionally, the first indication information (the sequence carrying the first indication information) is used to indicate the transmission content and the resource location of the transmission resource corresponding to the transmission content in the second transmission resource, and the time domain resource corresponding to the first indication information is used to jointly indicate the transmission parameter corresponding to the transmission content.

[0581] As shown in the (a) part of FIG. 25, when the sequence is 0, the transmission content on the second transmission resource is indicated as transmission DCI. The 4 first transmission resources are divided into two groups, the time domain resources of the first group and the second group are different, and the time domain resources corresponding to the 2 first transmission resources on each group are used to indicate the transmission parameters corresponding to the transmission content on the second transmission resource. For example, in a process of one-time repeated transmission, the time domain resources corresponding to the 2 first transmission resources in the first group are used to indicate that the DCI aggregation level of the transmission on the second transmission resource is 1, i.e., the time domain resources corresponding to the first transmission resources with index 0 and index 1 are used to indicate that the DCI aggregation level of the transmission on the second transmission resource is 1. For example, in another process of repeated transmission, the time domain resources corresponding to the 2 first transmission resources in the second group are used to indicate that the DCI aggregation level of the transmission on the second transmission resource is 2, i.e., the time domain resources corresponding to the first transmission resources with index 2 and index 3 are used to indicate that the DCI aggregation level of the transmission on the second transmission resource is 2. The sequence carrying the first indication information can indicate the resource position of the transmission content in the second transmission resource, for example, when the sequence is 0, the resource position of the transmission DCI corresponding to the transmission resource in the second transmission resource is the time domain starting position A.

[0582] As shown in the (b) part of FIG. 25, when the sequence is 1, the transmission content on the second transmission resource is indicated as transmission downlink data. The 4 first transmission resources are divided into two groups, and the time domain resources of the first group and the second group are different. The time domain resources corresponding to the 2 first transmission resources on each group are used to indicate the transmission parameters corresponding to the transmission content on the second transmission resource. For example, in a process of one-time repeated transmission, the time domain resources corresponding to the 2 first transmission resources in the first group are used to indicate that the modulation mode of the downlink data transmitted on the second transmission resource is QPSK, i.e., the time domain resources corresponding to the first transmission resources with index 0 and index 1 are used to indicate that the modulation mode of the downlink data transmitted on the second transmission resource is QPSK. For example, in another process of repeated transmission, the time domain resources corresponding to the 2 first transmission resources in the second group are used to indicate that the modulation mode of the downlink data transmitted on the second transmission resource is 16QAM, i.e., the time domain resources corresponding to the first transmission resources with index 2 and index 3 are used to indicate that the modulation mode of the downlink data transmitted on the second transmission resource is 16QAM. The sequence carrying the first indication information is used to indicate the resource position of the transmission content corresponding to the transmission resource in the second transmission resource, for example, when the sequence is 1, the resource position of the downlink data corresponding to the transmission resource in the second transmission resource is the time domain starting position B.

[0583] 3) The first indication information is used to indicate the first kind of transmission information, the first part of the second information associated with the first indication information is used to indicate the second kind of transmission information, and the second part of the second information associated with the first indication information is used to indicate the third kind of transmission information

[0584] The first part of the second information is a part of the second information, and the second part of the second information is another part of the second information. Any two parts of the second information in the first part of the second information and the second part of the second information are different or not completely the same.

[0585] In some embodiments, the transmission information on the second transmission resource is of three kinds, the first indication information based on the repeated transmission indicates the first kind of transmission information, the first part of the second information associated with the first indication information indicates the second kind of transmission information, and the second part of the second information associated with the first indication information indicates the second kind of transmission information.

[0586] In some embodiments, the part of the second information associated with the first indication information can also be understood as at least one kind of second information associated with the first indication information.

[0587] In some embodiments, the second information can be considered to be of eight kinds, that is, the second information includes at least one of the time domain resource corresponding to the first indication information, the frequency domain resource corresponding to the first indication information, the initial value corresponding to the sequence, the cyclic shift value corresponding to the sequence, the group number corresponding to the sequence, the intra-group root sequence number corresponding to the sequence, the sequence length corresponding to the sequence, and the sequence index corresponding to the sequence.

[0588] For example, the first indication information indicates that there is DCI or downlink data transmission on the second transmission resource, the time domain resource corresponding to the first indication information is used to indicate that the transmission content on the second transmission resource is transmission DCI, and the frequency domain resource corresponding to the first indication information is used to indicate the aggregation level corresponding to the DCI.

[0589] For another example, the first indication information indicates the resource position of the transmission resource in the second transmission resource, the time domain resource corresponding to the first indication information is used to indicate the transmission content on the second transmission resource, and the sequence length corresponding to the sequence carrying the first indication information is used to indicate the transmission parameter corresponding to the transmission content. The above is only an exemplary illustration, and the present application is not limited in this regard.

[0590] 4) The first part of the second information associated with the first indication information is used to indicate the first kind of transmission information, the second part of the second information associated with the first indication information is used to indicate the second kind of transmission information, and the third part of the second information associated with the first indication information is used to indicate the third kind of transmission information

[0591] The first part of the second information is a part of the second information, the second part of the second information is another part of the second information, and the third part of the second information is another part of the second information. Any two parts of the second information in the first part of the second information, the second part of the second information, and the third part of the second information are different or not completely the same.

[0592] In some embodiments, the transmission information on the second transmission resource is of three kinds, a first part of the second information associated with the first indication information is used to indicate a first kind of transmission information, a second part of the second information associated with the first indication information is used to indicate a second kind of transmission information, and a third part of the second information associated with the first indication information is used to indicate a third kind of transmission information.

[0593] In some embodiments, a part of the second information associated with the first indication information, which can also be understood as at least one kind of second information associated with the first indication information.

[0594] In some embodiments, the second information can be considered to be of eight kinds, i.e., the second information includes at least one of the time domain resource corresponding to the first indication information, the frequency domain resource corresponding to the first indication information, the initial value corresponding to the sequence, the cyclic shift value corresponding to the sequence, the group number corresponding to the sequence, the intra-group root sequence number corresponding to the sequence, the sequence length corresponding to the sequence, and the sequence index corresponding to the sequence.

[0595] For example, the time domain resource corresponding to the first indication information is used to indicate that there is DCI or downlink data transmission on the second transmission resource, the frequency domain resource associated with the first indication information is used to indicate that the transmission content on the second transmission resource is transmission of DCI, and the initial value corresponding to the sequence carrying the first indication information is used to indicate the aggregation level corresponding to the DCI.

[0596] For another example, the time domain resource corresponding to the first indication information is used to indicate that the transmission content on the second transmission resource is transmission of downlink data, the frequency domain resource corresponding to the first indication information is used to indicate the modulation mode of the downlink data, and the cyclic shift value corresponding to the sequence carrying the first indication information is used to indicate the time domain starting position of the transmission resource corresponding to the downlink data on the second transmission resource. The above is only an exemplary illustration, and the present application is not limited in this regard.

[0597] Regarding the first indication information being used to indicate a first kind of transmission information, a part of the second information associated with the first indication information being used to indicate a second kind of transmission information, and the information combination of the first indication information and the part of the second information associated with the first indication information being used to indicate a third kind of transmission information; or, the first indication information being used to indicate a first kind of transmission information, the information combination of the first indication information and a first part of the second information associated with the first indication information being used to indicate a second kind of transmission information, and a second part of the second information associated with the first indication information being used to indicate a third kind of transmission information; or, the first part of the second information associated with the first indication information being used to indicate a first kind of transmission information, the information combination of the first indication information and the first part of the second information associated with the first indication information being used to indicate a second kind of transmission information, and the second part of the second information associated with the first indication information being used to indicate a third kind of transmission information. The implementation manner can refer to the above content, which will not be described herein again.
