[0072] The mobile communication system provided by the embodiments of the application can be applied to, but is not limited to, at least one of the following communication scenarios: an uplink communication scenario, a downlink communication scenario, and a sidelink communication scenario.

[0073] Next, the related technologies involved in the embodiments of the application are introduced:

[0074] · Physical downlink control channel detection

[0075] 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 a 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.

[0076] Table 1

[0077] In the 5G NR system, DCI adopts Polar coding, and the terminal needs to perform decoding processing every time PDCCH detection is performed, which can cause high power consumption and increase processing delay.

[0078] 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 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 the transmission reliability is also different, for example, the more CCEs occupied by the PDCCH, the higher the transmission reliability.

[0079] Table 2

[0080] ·Terminal device complexity optimization:

[0081] 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 20 MHz, and a larger bandwidth is implemented through multi-carrier aggregation. The maximum carrier bandwidth of 5G NR in a low-frequency band below 6 GHz is finally defined as 100 MHz, which is 5 times of that of LTE, and the maximum carrier bandwidth of a millimeter wave frequency band is 400 MHz. 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 2500 MHz.

[0082] 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, it is required that the communication hardware has a lower volume and power consumption, and the capability requirement of lightness is a feature of such terminals. Based on such considerations, the NR R17 research introduces a compact terminal standard of Reduce capability (RedCap).

[0083] 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 procedures, and optimized measurements to adapt to the relevant application scenarios. The design of such a compact terminal can significantly reduce the complexity of terminal hardware. At the same time, the energy consumption of the terminal can also be reduced accordingly, and the effect of energy saving can be achieved.

[0084] Before introducing the technical solutions of the present application, some contents related to the present application are introduced and explained. The following contents can be combined with the technical solutions of the embodiments of the present application as optional solutions, and 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.

[0085] 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.

[0086] 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 includes downlink data and / or downlink control information (DCI). The embodiments below are mainly exemplified by taking the other transmission resources as 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.

[0087] 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.

[0088] Correspondence between the first transmission resource and the second transmission resource

[0089] In some embodiments, the correspondence can also be referred to as an association relationship.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] FIG. 2 shows a schematic diagram of the correspondence between the transmission resources according to an example embodiment of the present application.

[0094] 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.

[0095] Position relationship between the first transmission resource and the second transmission resource

[0096] 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.

[0097] 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:

[0098] 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.

[0099] 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.

[0100] FIG. 3 shows a schematic diagram of the position relationship between the transmission resources according to an example embodiment of the present application.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] The type of the first transmission resource and the second transmission resource

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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 to transmit 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 to transmit 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.

[0121] 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.

[0122] For example, FIG. 4 shows a schematic diagram of configuring transmission resources provided by an example embodiment of the present application.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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 dedicated DCI or dedicated downlink data of each terminal device.

[0127] 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.

[0128] 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.

[0129] Indication manner of the first indication information

[0130] 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:

[0131] Manner 1: indicating that the second transmission resources are not transmitted.

[0132] 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;

[0133] 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.

[0134] 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 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 repeated here.

[0135] 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.

[0136] Mode 2: Indicate that the DCI or PDCCH is transmitted on the second transmission resource.

[0137] In some embodiments, based on the first indication information, the DCI or PDCCH is received on the second transmission resource.

[0138] 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.

[0139] Optionally, a second value, a second state or a second sequence is determined based on the first indication information, and it is determined that the DCI or PDCCH is transmitted on the second transmission resource based on the second value, the second state or the second sequence.

[0140] Mode 3: Indicate that the first downlink data is transmitted on the second transmission resource.

[0141] 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 first downlink data is not indicated to be transmitted on the second transmission resource, it is not necessary to detect the first downlink data on the second transmission resource.

[0142] 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.

[0143] Optionally, the first downlink data is carried by PDSCH;

[0144] Optionally, a third value, a third state or a third sequence is determined based on the first indication information, and it is determined that the first downlink data is transmitted on the second transmission resource based on the third value, the third state or the third sequence.

[0145] Mode 4: Indicate that the DCI and the first downlink data are transmitted on the second transmission resource.

[0146] 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.

[0147] By way of example but not limitation, the DCI is used for scheduling the second downlink data, or, the DCI is used for scheduling the second uplink data.

[0148] In some embodiments, the DCI used for scheduling the second downlink data includes: the DCI used for indicating the transmission resource of the second downlink data, and / or, the DCI used for indicating the transmission parameter of the second downlink data; the DCI used for scheduling the second uplink data includes: the DCI used for indicating the transmission resource of the second uplink data, and / or, the DCI used for indicating the transmission parameter of the second uplink data.

[0149] Characteristics of the first indication information

[0150] 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 for carrying 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 and a ZC (Zaddoff Chu) sequence. The real sequence includes at least one of a pseudo-random sequence, a Gold sequence, an m-sequence, and a Hadamard sequence. Alternatively, the sequence used for carrying the first indication information is generated or determined based on the above sequence types.

[0151] The first indication information is transmitted in a sequence manner, so that the terminal device can 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.

[0152] 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; and the size of the frequency domain resource included in the first transmission resource.

[0153] 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 preset positive integer, for example, A = 2 or 4.

[0154] 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.

[0155] In some embodiments, the first indication information is carried by at least one bit, including the at least one bit being processed by channel coding, modulation, etc. to generate a data packet or a transport block.

[0156] The first indication information is carried by a sequence or at least one bit

[0157] 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.

[0158] Alternatively, the correspondence between the sequence index and the transmission content is determined by protocol predefined information or network configuration information.

[0159] 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.

[0160] Table 3

[0161] 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.

[0162] 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 network configured correspondence includes K sequence indexes, and the corresponding transmission contents are also K, where K is an integer greater than or equal to 1.

[0163] The first indication information is used to indicate a first value

[0164] In some embodiments, the first indication information is used to indicate a first value, and the first value is associated with the transmission content.

[0165] Optionally, the correspondence between the first value and the transmission content is determined by protocol predefined information or network configuration information.

[0166] 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:

[0167] Table 4

[0168] 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 "transmitting the second DCI on the second transmission resource"; when the first value is 2, the corresponding transmission content is "transmitting the first downlink data on the second transmission resource"; and when the first value is 3, the corresponding transmission content is "transmitting 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.

[0169] 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 contents 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.

[0170] determining the transmission content on the second transmission resource based on the first indication information and / or the first information associated with the first indication information

[0171] 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 first 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 first information associated with the first indication information.

[0172] 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.

[0173] In some embodiments, the first 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, and 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, a root sequence number within a group corresponding to the first sequence, a sequence length corresponding to the first sequence, and a sequence index corresponding to the first sequence. The first sequence is used to carry the first indication information.

[0174] 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.

[0175] 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. The sequence is used to carry the first indication information.

[0176] 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. The sequence is used to carry the first indication information.

[0177] 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.

[0178] In some embodiments, the transmission content on the second transmission resource is determined based on different values of the first information associated with the first indication information. It can be understood that the different values of the first information associated with the first indication information indicate the transmission content on the second transmission resource.

[0179] For example, the first indication information is used to indicate the transmission content on the second transmission resource. The first indication information is carried by a first sequence or at least one bit. Different values of the first sequence or at least one bit can be used to indicate the transmission content on the second transmission resource.

[0180] For example, the first information is used to indicate the transmission content on the second transmission resource. At least five different indication methods can be used to indicate the transmission content on the second transmission resource. The first sequence is used to carry the first indication information.

[0181] Indication method A: the length of the first sequence is used to indicate the transmission content on the second transmission resource.

[0182] Indication mode B: the transmission content on the second transmission resource is indicated based on the frequency domain resource corresponding to the first indication information;

[0183] Indication mode C: the transmission content on the second transmission resource is indicated based on the time domain resource corresponding to the first indication information;

[0184] Indication mode D: the transmission content on the second transmission resource is indicated based on the sequence index corresponding to the first sequence;

[0185] Indication mode E: the transmission content on the second transmission resource is indicated based on the sequence group index corresponding to the first sequence.

[0186] In some embodiments, the transmission content on the second transmission resource includes at least one of the following:

[0187] No transmission on the second transmission resource; transmission of DCI or PDCCH on the second transmission resource; transmission of first downlink data on the second transmission resource; transmission of DCI and first downlink data on the second transmission resource.

[0188] For indication mode A: the transmission content on the second transmission resource is indicated based on the length corresponding to the first sequence;

[0189] There is an association or correspondence between the sequence length and the transmission content, which is determined based on protocol predefined information or network configuration information.

[0190] For example, based on the length corresponding to the first sequence to indicate one transmission content on the second transmission resource, length index value 1 indicates no transmission on the second transmission resource, length index value 2 indicates transmission of DCI or PDCCH on the second transmission resource, length index value 3 indicates transmission of first downlink data on the second transmission resource, etc., which is not limited in the present application.

[0191] For indication mode B: the transmission content on the second transmission resource is indicated based on the frequency domain resource corresponding to the first indication information;

[0192] There is an association or correspondence between the frequency domain resource corresponding to the first indication information and the transmission content, which is determined based on protocol predefined information or network configuration information.

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

[0194] For example, based on the frequency domain resource corresponding to the first indication information to indicate a transmission content on the second transmission resource, the frequency domain resource index value 1 indicates that there is no transmission on the second transmission resource, the frequency domain resource index value 2 indicates that the DCI or PDCCH is transmitted on the second transmission resource, and the frequency domain resource index value 3 indicates that the first downlink data is transmitted on the second transmission resource, and the present application does not limit this.

[0195] For indication mode C: based on the time domain resource corresponding to the first indication information to indicate the transmission content on the second transmission resource.

[0196] 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.

[0197] The time domain resource corresponding to the first indication information can be understood as the time domain resource corresponding to the first transmission resource where the first indication information is located; or, can be understood as the time domain resource corresponding to the first indication information in the first transmission resource; or, can be understood as the time domain resource carrying the first indication information in the first transmission resource.

[0198] For example, based on the time domain resource corresponding to the first indication information to indicate a transmission content on the second transmission resource, the time domain resource index value 1 indicates that there is no transmission on the second transmission resource, the time domain resource index value 2 indicates that the DCI or PDCCH is transmitted on the second transmission resource, and the time domain resource index value 3 indicates that the first downlink data is transmitted on the second transmission resource, and the present application does not limit this.

[0199] For indication mode D: based on the sequence index corresponding to the first sequence to indicate the transmission content on the second transmission resource.

[0200] 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.

[0201] For example, based on the sequence index corresponding to the first sequence to indicate a transmission content on the second transmission resource, the sequence index 1 indicates that there is no transmission on the second transmission resource, the sequence index 2 indicates that the DCI or PDCCH is transmitted on the second transmission resource, and the sequence index 3 indicates that the first downlink data is transmitted on the second transmission resource, and the present application does not limit this.

[0202] For indication mode E: based on the sequence group index corresponding to the first sequence to indicate the transmission content on the second transmission resource.

[0203] The sequence group 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.

[0204] For example, the first sequence corresponds to a sequence group index indicating one transmission content on the second transmission resource, 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, the sequence group index 3 indicates transmission of first downlink data on the second transmission resource, and the like, which are not limited in the present application.

[0205] 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, 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.

[0206] The second transmission resource

[0207] In some embodiments, the second transmission resource is used for transmission of 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.

[0208] 1) The second transmission resource is used for transmission of DCI

[0209] The first transmission resource transmits first indication information, which indicates transmission of DCI on the second transmission resource. Optionally, the DCI is used for scheduling transmission of uplink data (e.g., PUSCH), or is used for scheduling transmission of downlink data (e.g., PDSCH), or is used for other purposes, which are not limited in the embodiments of the present application.

[0210] FIG. 7 shows a schematic diagram of DCI scheduling data provided by one exemplary embodiment of the present application.

[0211] In (a) of FIG. 7, when the DCI is used for scheduling 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, for the terminal device to perform downlink data reception based on the indicated parameters.

[0212] In (b) of FIG. 7, when the DCI is used for scheduling 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, for the terminal device to perform uplink data transmission based on the indicated parameters.

[0213] In some embodiments, the DCI is carried by PDCCH, and the network device configures a search space in the second transmission resource by sending network configuration information, and the terminal device detects PDCCH in the search space.

[0214] Optionally, the DCI is carried on PDCCH or PDSCH.

[0215] In some embodiments, the following information is determined based on the protocol predefined information or the network configuration information:

[0216] DCI format corresponding to the DCI; bit number corresponding to the DCI; Radio Network Temporary Identifier (RNTI) corresponding to the DCI; encoding mode corresponding to the DCI; encoding code rate corresponding to the DCI; CCE number corresponding to the DCI; aggregation level corresponding to the DCI; and candidate PDCCH number associated with the aggregation level.

[0217] The bit number corresponding to the DCI corresponds to a maximum bit number, and the encoding mode includes a Polar code, a Low Density Parity Check (LDPC) code, or a small block length encoding.

[0218] 2) The second transmission resource is used to transmit the first downlink data

[0219] In some embodiments, the second transmission resource is used to transmit downlink data, and the downlink data is carried by a PDSCH.

[0220] Since the transmission resource indication information and the transmission parameter indication information are not included in the first indication information, the transmission parameter corresponding to the downlink data is determined based on the protocol predefined information or the network configuration information.

[0221] 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:

[0222] 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.

[0223] 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.

[0224] Optionally, the DMRS information corresponding to the downlink data is determined by 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.

[0225] 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).

[0226] 3) No transmission on the second transmission resource

[0227] In some embodiments, there is no transmission on the second transmission resource.

[0228] In some embodiments, the terminal determines whether there is transmission on the second transmission resource or whether it needs to detect the second transmission resource 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.

[0229] In some embodiments, the terminal determines whether there is transmission on the second transmission resource or whether it needs to detect the second transmission resource based on whether the first indication information is detected.

[0230] In some embodiments, the terminal detects the first indication information on the first transmission resource, and the first indication information indicates that there is no transmission on the second transmission resource, so the terminal does not need to detect the second transmission resource.

[0231] 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 means that there is no transmission on the second transmission resource, so the terminal does not need to detect the second transmission resource.

[0244] Taking the case of indicating the transmission parameter by using the first indication information, the first indication information is carried by the first sequence or at least one bit, and different first sequences or different values of at least one bit can be used to indicate the transmission parameter.

[0245] Taking the case of indicating the transmission parameter by using the first information, 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.

[0255] 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;

[0256] 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. Optionally, 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.

[0259] 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.

[0260] 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.

[0261] 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.

[0262] For 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 4 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 simultaneously transmit the DCI of the four UEs 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 by the four UEs on the second transmission resource.

The unit of the time unit is any one of a frame, a subframe, a slot, a mini-slot, a sub-slot, a symbol, a symbol group, and a unit based on another time domain unit. It should be noted that the time unit is not limited to the above-mentioned units, and a unit agreed by a future communication protocol is also applicable to the present application.

[0285] In some embodiments, the resource location comprises a location in a frequency domain dimension.

By mapping the VRB to the dispersed PRB, the influence of interference can be reduced.

[0288] In some embodiments, there is a corresponding relationship between the information combination of the first indication information and the first information and the resource location. For example, when the first indication information is carried by a sequence, sequence 0 and time domain location 0 of the first transmission resource represent resource location 0 in the second transmission resource; sequence 0 and time domain location 1 of the first transmission resource represent resource location 1 in the second transmission resource; sequence 1 and time domain location 0 of the first transmission resource represent resource location 2 in the second transmission resource; and sequence 1 and time domain location 1 of the first transmission resource represent resource location 3 in the second transmission resource.

[0294] In some embodiments, a combination of information formed by the first indication information and the at least one first information is used to indicate all or part of the resource locations of the transmission resource corresponding to the downlink transmission content in the second transmission resource. For example, a combination of information formed by the first indication information and the at least one first information indicates at least one of a resource start location, a resource end location, and a resource size of the transmission resource corresponding to the downlink transmission content in the second transmission resource.

[0295] Embodiments of the present application mainly determine the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the first information associated with the first indication information.

[0296] In summary, the method provided by the embodiments of the present application, the terminal device receives the first indication information on the first transmission resource configured by the network device, and the first information associated with the first indication information has a corresponding relationship between the transmission resource corresponding to the downlink transmission content and the resource position in the second transmission resource. The terminal device can determine the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource based on the first information. By detecting the first indication information on the first transmission resource, compared with the PDCCH monitoring in the prior art, on the one hand, it is not necessary to monitor or frequently blind detect the PDCCH for a long time, which reduces the workload related to monitoring and is conducive to energy saving and consumption reduction of the terminal device.

[0297] On the other hand, when multiple terminal devices or multiple first transmission resources share one second transmission resource, the terminal device can determine the associated first information based on the detected first indication information, for example, determine the associated first information based on the detected sequence, and then determine the resource position of the transmission resource corresponding to the downlink transmission content in the second transmission resource. In this way, the first information can accurately locate the resource position of the current transmission in the second transmission resource, reduce the complexity of detecting the transmission content on the second transmission resource, and is conducive to energy saving and consumption reduction of the terminal device. In addition, one first transmission resource is used to indicate multiple information, which improves the resource utilization rate.

By detecting the first indication information on the first transmission resource, compared with the PDCCH monitoring in the prior art, on the one hand, long-time monitoring or frequent blind detection is not required, the workload related to monitoring is reduced, and energy saving and consumption reduction of the terminal device are facilitated.

[0330] On the other hand, when multiple terminal devices or first transmission resources share one second transmission resource, the terminal device can determine the associated first information based on the detected first indication information, for example, determine the associated first information based on the detected sequence, and further determine the resource location of the transmission resource corresponding to the downlink transmission content in the second transmission resource. In this way, the resource location of the current transmission can be accurately located in the second transmission resource through the first information, reducing the complexity of detecting the transmission content on the second transmission resource, which is beneficial to the energy saving and consumption reduction of the terminal device, and one first transmission resource can indicate multiple information, improving the resource utilization.

Wherein, each of the at least two first transmission resources can be used to transmit the first indication information. Optionally, the first indication information transmitted on different first transmission resources is associated with different first information, and the first information has a corresponding relationship with the resource position. Wherein, "different first transmission resources" are associated with "different first information", which can mean that all different first transmission resources are associated with different first information, or that part of the different first transmission resources are associated with different first information. Part of the different can be understood as at least two different. The present application does not limit this.

[0349] In some embodiments, the first information includes the time domain resource corresponding to the first indication information, and the first indication information transmitted on different first transmission resources is associated with different time domain resources. It can also be understood that there are at least two first transmission resources associated with different time domain resources, or part of the first transmission resources are associated with different time domain resources.

[0355] In the following, taking the resource position comprising a resource start position as an example. Optionally, the resource start position comprises at least one of a time domain start position, a frequency domain start position, and a logical resource unit start position.

[0356] 1. The time domain resource and the resource start position have a correspondence relationship

[0357] In some embodiments, the network device configures multiple (at least two) first transmission resources corresponding to the second transmission resource, i.e., the second transmission resource is associated with at least two first transmission resources in a group of transmission resources. Optionally, the first indication information transmitted on different first transmission resources is associated with different first information.

[0358] In some embodiments, the first information comprises the time domain resource corresponding to the first indication information.

[0359] 1.1. The time domain resource and the time domain start position have a correspondence relationship

[0360] In some embodiments, different time domain resources correspond to different time domain start positions, i.e., based on the time domain resource corresponding to the first indication information to determine the time domain start position of the transmission resource corresponding to the downlink transmission content in the second transmission resource, which can also be understood as, based on the sequence carrying the first indication information or the time domain resource corresponding to the at least one bit carrying the first indication information, to determine the time domain start position of the transmission resource corresponding to the downlink transmission content in the second transmission resource. Wherein, the time domain start position refers to the start position of the transmission content in the time domain dimension on the second transmission resource.

[0361] In some embodiments, the network device configures N1 first transmission resources corresponding to the second transmission resource for the terminal device, i.e., the second transmission resource is associated with N1 first transmission resources, and N1 is a positive integer greater than 1. The first indication information transmitted on the N1 first transmission resources is associated with N1 time domain resources. Each of the N1 time domain resources can be used to transmit the first indication information, or it is understood that each of the N1 time domain resources can be used to transmit a sequence or at least one bit carrying the first indication information. The second transmission resource includes M1 time domain starting positions, and the first correspondence relationship between the N1 time domain resources and the M1 time domain starting positions is one-to-one correspondence, or many-to-one correspondence, or one-to-many correspondence.

[0362] 1) One-to-one correspondence between time domain resources and time domain starting positions

[0363] For example, as shown in part (a) of FIG. 12, the network device configures 4 first transmission resources and 1 second transmission resource associated with the terminal device, i.e., the second transmission resource is associated with 4 first transmission resources, and the 4 first transmission resources are respectively associated with 4 OFDM symbols, each of which can be used to transmit a sequence carrying the first indication information. The second transmission resource includes 4 time domain starting positions. The network device configures the first correspondence relationship between the OFDM symbols transmitting the first indication information and the time domain starting positions as one-to-one correspondence. The network device configures the first correspondence relationship between the OFDM symbols and the time domain starting positions on the second transmission resource as shown in Table 5.

[0364] Table 5

[0365] For example, the first information includes time domain resources corresponding to the first indication information, and the time domain resources include OFDM symbols. For example, the network device configures 4 first transmission resources, and the sequence of the first indication information transmitted on the 4 first transmission resources is associated with 4 OFDM symbols, and the time domain starting positions on the second transmission resource (the time domain starting positions corresponding to the transmission content on the second transmission resource) include 4 time domain starting positions. Different time domain resources (OFDM symbols) have a first correspondence relationship with different time domain starting positions. Alternatively, the first transmission resource with OFDM symbol 0 transmits the first indication information corresponding to the time domain starting position A on the second transmission resource; the first transmission resource with OFDM symbol 1 transmits the first indication information corresponding to the time domain starting position B on the second transmission resource; the first transmission resource with OFDM symbol 2 transmits the first indication information corresponding to the time domain starting position C on the second transmission resource; and the first transmission resource with OFDM symbol 3 transmits the first indication information corresponding to the time domain starting position D on the second transmission resource.

[0366] It should be noted that the above Table 5 is only an exemplary description of the first correspondence relationship between the time domain resources corresponding to the first indication information and the time domain starting positions on the second transmission resources, and the method in the embodiments of the present application is not limited to the correspondence relationship in Table 5. In some embodiments, the correspondence 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 correspondence relationship configured by the network includes K OFDM symbols, and the corresponding time domain starting positions are also K, where K is an integer greater than or equal to 1.

[0367] 2) One-to-many correspondence relationship between time domain resources and time domain starting positions

[0368] For example, as shown in part (b) of FIG. 12, the network device configures 4 first transmission resources and 1 second transmission resource associated with the terminal device by taking the sequence carrying the first indication information as an example, that is, the second transmission resource is associated with 4 first transmission resources, and the 4 first transmission resources are respectively associated with 4 OFDM symbols, and each OFDM symbol 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-many correspondence relationship between the OFDM symbols transmitting the first indication information and the time domain starting positions. The network device configures the first correspondence relationship between the OFDM symbols and the time domain starting positions on the second transmission resource as shown in Table 6.

[0369] Table 6

[0370] For example, the first information includes time domain resources corresponding to the first indication information, and the time domain resources include OFDM symbols. The first correspondence relationship between the OFDM symbols and the time domain starting positions is a one-to-many correspondence relationship, that is, a plurality of OFDM symbols correspond to one time domain starting position. Alternatively, when the first transmission resources with OFDM symbols 0 and 1 transmit the first indication information, they correspond to the time domain starting position A on the second transmission resource; when the first transmission resources with OFDM symbols 2 and 3 transmit the first indication information, they correspond to the time domain starting position C on the second transmission resource.

[0371] In some embodiments, when a plurality of time domain resources indicate a time domain starting position on a second transmission resource, the transmission contents corresponding to the transmission resources indicated by different time domain resources on the second transmission resource are different in size.

[0372] For example, when the OFDM symbol is 0, the DCI aggregation level indicated by the sequence carrying the first indication information is 1, the time domain starting position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is time domain starting position A, and the transmission resource size includes the transmission resource between time domain starting positions A and B; when the OFDM symbol is 1, the DCI aggregation level indicated by the sequence carrying the first indication information is 2, the time domain starting position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is time domain starting position A, and the transmission resource size includes the transmission resource between starting positions A and C. When the OFDM symbol is 2, the DCI aggregation level indicated by the sequence carrying the first indication information is 1, the time domain starting position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is time domain starting position C, and the transmission resource size includes the transmission resource between time domain starting positions C and D; when the OFDM symbol is 3, the DCI aggregation level indicated by the sequence carrying the first indication information is 2, the time domain starting position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is time domain starting position C, and the transmission resource size includes the transmission resource between time domain starting position C and the time domain ending position of the second transmission resource.

[0373] It should be noted that the above Table 6 is only an exemplary description of the first correspondence relationship between the time domain resource and the time domain starting position on the second transmission resource, and the method in the embodiments of the present application is not limited to the correspondence relationship in Table 6. 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 network configured correspondence relationship includes K OFDM symbols, and the corresponding time domain starting positions are also K, where K is an integer greater than or equal to 1.

[0374] 3) One-to-many correspondence relationship between time domain resource and time domain starting position

[0375] For example, as shown in part (c) of FIG. 12, taking the sequence carrying the first indication information as an example, the network device configures 4 first transmission resources and 1 second transmission resource associated with the terminal device, i.e., the second transmission resource is associated with 4 first transmission resources, and the 4 first transmission resources are respectively associated with 4 OFDM symbols, which 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-many correspondence relationship between the OFDM symbol and the time domain starting position for transmitting the first indication information. The network device configures the first correspondence relationship between the OFDM symbol and the time domain starting position on the second transmission resource as shown in Table 7.

[0376] Table 7

[0377] The first information includes, for example, time domain resources corresponding to the sequence first indication information, and the time domain resources include OFDM symbols. The first correspondence relationship between the OFDM symbols and the time domain starting positions is a one-to-many correspondence relationship. Alternatively, when the first indication information is transmitted on the first transmission resource with the OFDM symbol being 0, the time domain starting position corresponding to the second transmission resource can be any one of the time domain starting position A, the time domain starting position B, the time domain starting position C, and the time domain starting position D.

[0378] Alternatively, the OFDM symbol determines the time domain starting position in combination with other information. For example, the other information can be an aggregation level, and the OFDM symbol determines the time domain starting position on the second transmission resource in combination with the DCI aggregation level indicated by the sequence indicating the first indication information. For example, when the OFDM symbol is 0, the DCI aggregation level indicated by the sequence indicating the first indication information is 4, the time domain starting position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is the time domain starting position A, and the transmission resource size includes the transmission resource between the time domain starting position A and the time domain ending position of the second transmission resource; when the OFDM symbol is 0, the DCI aggregation level indicated by the sequence indicating the first indication information is 3, the time domain starting position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is the time domain starting position B, and the transmission resource size includes the transmission resource between the time domain starting position B and the time domain ending position of the second transmission resource; when the OFDM symbol is 0, the DCI aggregation level indicated by the sequence indicating the first indication information is 2, the time domain starting position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is the time domain starting position C, and the transmission resource size includes the transmission resource between the time domain starting position C and the time domain ending position of the second transmission resource; when the OFDM symbol is 0, the DCI aggregation level indicated by the sequence indicating the first indication information is 1, the time domain starting position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is the time domain starting position D, and the transmission resource size includes the transmission resource between the time domain starting position D and the time domain ending position of the second transmission resource.

[0379] It should be noted that the above table 7 is only an exemplary description of the first correspondence relationship between the time domain resources and the time domain starting positions on the second transmission resource, and the method in the embodiments of the present application is not limited to the correspondence relationship in the table 7. In some embodiments, the correspondence relationship configured by the network only includes part of the content in the above table, such as any 2 rows in the above table; in some embodiments, the OFDM symbol included in the correspondence relationship configured by the network is K, and the corresponding time domain starting position is also K, where K is an integer greater than or equal to 1.

[0380] 1.2 Correspondence relationship between time domain resources and frequency domain starting positions

[0381] In some embodiments, different time domain resources correspond to different frequency domain starting positions, that is, the frequency domain starting position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the time domain resource corresponding to the first indication information, which can also be understood as determining the frequency domain starting 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 sequence carrying the first indication information or the at least one bit carrying the first indication information. The frequency domain starting position refers to the starting position of the transmission content in the frequency domain dimension on the second transmission resource.

[0382] In some embodiments, the network device configures N2 first transmission resources corresponding to the second transmission resource for the terminal device, that is, the second transmission resource is associated with N2 first transmission resources, and N2 is a positive integer greater than 1. The first indication information transmitted on the N2 first transmission resources is associated with N2 time domain resources. Each of the N2 time domain resources can be used to transmit the first indication information, or it can be understood that each of the N2 time domain resources can be used to transmit the sequence carrying the first indication information or the at least one bit. The second transmission resource includes M2 frequency domain starting positions, and the first correspondence relationship between the N2 time domain resources and the M2 frequency domain starting positions is one-to-one correspondence, or many-to-one correspondence, or one-to-many correspondence.

[0383] 1) One-to-one correspondence between time domain resources and frequency domain starting positions

[0384] For example, in combination with reference to FIG. 13, as shown in part (a) of FIG. 13, taking the sequence carrying the first indication information as an example, the network device configures the terminal device with 4 associated first transmission resources and 1 second transmission resource, that is, the second transmission resource is associated with 4 first transmission resources, and the 4 first transmission resources are respectively associated with 4 OFDM symbols, each of which can be used to transmit the sequence carrying the first indication information. The second transmission resource includes 4 frequency domain starting positions. The network device configures the first correspondence relationship between the OFDM symbol transmitting the first indication information and the frequency domain starting position as one-to-one correspondence. The network device configures the first correspondence relationship between the OFDM symbol and the time domain starting position on the second transmission resource as shown in Table 8.

[0385] Table 8

[0386] For example, the first information includes time domain resources corresponding to the first indication information, and the time domain resources include OFDM symbols. The network device configures four first transmission resources, and the sequences transmitted on the four first transmission resources are associated with four OFDM symbols. For example, the second transmission resource includes four frequency domain starting positions, and different time domain resources (OFDM symbols) and different frequency domain starting positions have a first correspondence relationship. Optionally, when the first indication information is transmitted on the first transmission resource with the OFDM symbol 0, the frequency domain starting position a on the second transmission resource is used as the correspondence; when the first indication information is transmitted on the first transmission resource with the OFDM symbol 1, the frequency domain starting position b on the second transmission resource is used as the correspondence; when the first indication information is transmitted on the first transmission resource with the OFDM symbol 2, the frequency domain starting position c on the second transmission resource is used as the correspondence; and when the first indication information is transmitted on the first transmission resource with the OFDM symbol 3, the frequency domain starting position d on the second transmission resource is used as the correspondence.

[0387] It should be noted that the above Table 8 is only an exemplary description of the first correspondence relationship between the time domain resources and the frequency domain starting positions on the second transmission resource, and the method in the embodiments of the present application is not limited to the correspondence relationship in Table 8. In some embodiments, the correspondence relationship configured by the network includes only part of the content in the above table, for example, only any two rows in the above table; in some embodiments, the correspondence relationship configured by the network includes K OFDM symbols, and the corresponding frequency domain starting positions are also K, where K is an integer greater than or equal to 1.

[0388] 2) One-to-many correspondence relationship between time domain resources and frequency domain starting positions

[0389] For example, as shown in part (b) of FIG. 13, the network device configures four first transmission resources and one second transmission resource for the terminal device, that is, the second transmission resource is associated with the four first transmission resources, and the four first transmission resources are respectively associated with four OFDM symbols, each of which can be used to transmit the sequence carrying the first indication information. The second transmission resource includes four frequency domain starting positions. The network device configures a one-to-many correspondence relationship between the OFDM symbols transmitting the first indication information and the frequency domain starting positions. The network device configures the first correspondence relationship between the OFDM symbols and the frequency domain starting positions on the second transmission resource as shown in Table 9.

[0390] Table 9

[0391] For example, the first information includes the time-domain resources corresponding to the first indication information, and the time-domain resources include OFDM symbols. The first correspondence between OFDM symbols and frequency-domain start positions is a many-to-one correspondence, that is, multiple OFDM symbols correspond to one frequency-domain start position. Optionally, when the first indication information is transmitted on the first transmission resource where OFDM symbols are 0 and 1, it corresponds to the time-domain start position a on the second transmission resource; when the first indication information is transmitted on the first transmission resource where OFDM symbols are 2 and 3, it corresponds to the time-domain start position c on the second transmission resource.

[0392] In some embodiments, when multiple time-domain resources indicate the frequency domain start position on a second transmission resource, the transmission resource size corresponding to the transmission content on the second transmission resource indicated by different time-domain resources is different.

[0393] For example, when the OFDM symbol is 0, the DCI aggregation level of the sequence indicating the first indication information is 1, the frequency domain start position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is frequency domain start position a, and the transmission resource size includes the transmission resources between frequency domain start positions a and b; when the OFDM symbol is 1, the DCI aggregation level of the sequence indicating the first indication information is 2, the frequency domain start position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is frequency domain start position a, and the transmission resource size includes the transmission resources between frequency domain start positions a and c. When the OFDM symbol is 2, the DCI aggregation level of the sequence indicating the first indication information is 1, the frequency domain start position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is frequency domain start position c, and the transmission resource size includes the transmission resources between frequency domain start positions c and d; when the OFDM symbol is 3, the DCI aggregation level of the sequence indicating the first indication information is 2, the frequency domain start position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is frequency domain start position c, and the transmission resource size includes the transmission resources between frequency domain start position c and the frequency domain end position of the second transmission resource.

[0394] It should be noted that Table 9 above is merely an exemplary illustration of the first correspondence between the frequency domain start positions on the time domain resources and the second transmission resources. The method implemented in this application is not limited to the correspondence in Table 9. In some embodiments, the correspondence of network configuration only includes part of the content in the table above, such as only including any two rows in the table above; in some embodiments, the correspondence of network configuration includes K OFDM symbols, and their corresponding frequency domain start positions are also K, where K is an integer greater than or equal to 1.

[0395] 3) There is a one-to-many correspondence between time-domain resources and frequency-domain starting positions.

[0396] For example, with reference to FIG. 13, as shown in part (c) of FIG. 13, taking the first indication information carried by the sequence as an example, the network device configures the terminal device with 4 first transmission resources and 1 second transmission resource associated with the 4 first transmission resources, i.e., the second transmission resource is associated with the 4 first transmission resources, the 4 first transmission resources are respectively associated with 4 OFDM symbols, and the OFDM symbols can be used to transmit the sequence carrying the first indication information. The second transmission resource includes 4 frequency domain starting positions. The network device configures a one-to-many correspondence between the OFDM symbols and the frequency domain starting positions on the second transmission resource. The network device configures the first correspondence between the OFDM symbols and the frequency domain starting positions on the second transmission resource as shown in Table 10.

[0397] Table 10

[0398] For example, the first information includes a time domain resource corresponding to the first indication information, and the time domain resource includes an OFDM symbol. The first correspondence between the OFDM symbol and the frequency domain starting position is a one-to-many correspondence. Alternatively, when the first indication information is transmitted on the first transmission resource with the OFDM symbol being 0, the corresponding frequency domain starting position on the second transmission resource can be any one of the frequency domain starting position a, the frequency domain starting position b, the frequency domain starting position c, and the frequency domain starting position d.

[0399] Optionally, the OFDM symbol determines the frequency domain starting position in combination with other information. For example, the other information can be an aggregation level, and the OFDM symbol determines the frequency domain starting position on the second transmission resource in combination with the aggregation level of the DCI indicated by the sequence carrying the first indication information. For example, when the OFDM symbol is 0, the aggregation level of the DCI indicated by the sequence carrying the first indication information is 4, the frequency domain starting position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is frequency domain starting position a, and the size of the transmission resource includes the transmission resource between the frequency domain starting position a and the frequency domain end position of the second transmission resource; when the OFDM symbol is 0, the aggregation level of the DCI indicated by the sequence carrying the first indication information is 3, the frequency domain starting position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is frequency domain starting position b, and the size of the transmission resource includes the transmission resource between the frequency domain starting position b and the frequency domain end position of the second transmission resource; when the OFDM symbol is 0, the aggregation level of the DCI indicated by the sequence carrying the first indication information is 2, the frequency domain starting position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is frequency domain starting position c, and the size of the transmission resource includes the transmission resource between the frequency domain starting position c and the frequency domain end position of the second transmission resource; when the OFDM symbol is 0, the aggregation level of the DCI indicated by the sequence carrying the first indication information is 1, the frequency domain starting position of the transmission resource corresponding to the DCI transmitted on the second transmission resource is frequency domain starting position d, and the size of the transmission resource includes the transmission resource between the frequency domain starting position d and the frequency domain end position of the second transmission resource.

[0400] It should be noted that the above Table 10 is only an exemplary description of the first correspondence relationship between the time domain resource and the frequency domain starting position on the second transmission resource, and the method in the embodiments of the present application is not limited to the correspondence relationship in Table 10. In some embodiments, the correspondence 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 correspondence relationship configured by the network includes K OFDM symbols, and the corresponding frequency domain starting positions are also K, where K is an integer greater than or equal to 1.

[0401] 1.3 Correspondence relationship between time domain resource and logical resource unit starting position

[0402] In some embodiments, different time domain resources correspond to different logical resource unit starting positions, that is, the logical resource unit starting position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the time domain resource corresponding to the first indication information. It can also be understood that the logical resource unit starting position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the time domain resource corresponding to the sequence carrying the first indication information or at least one bit carrying the first indication information. The logical resource unit starting position refers to the starting position of the transmission content on the second transmission resource in the logical resource dimension.

[0403] In some embodiments, the network device configures N3 first transmission resources corresponding to the second transmission resource for the terminal device, that is, the second transmission resource is associated with N3 first transmission resources, and N3 is a positive integer greater than 1. The first indication information transmitted on the N3 first transmission resources is associated with N3 time domain resources. Each of the N3 time domain resources can be used to transmit the first indication information, or it can be understood that each of the N3 time domain resources can be used to transmit a sequence carrying the first indication information or at least one bit. The second transmission resource includes M3 time domain starting positions, and the first correspondence relationship between the N3 time domain resources and the M3 time domain starting positions is one-to-one correspondence, or many-to-one correspondence, or one-to-many correspondence.

[0404] 1) One-to-one correspondence between time domain resources and logical resource unit starting positions

[0405] For example, as shown in part (a) of FIG. 14, taking the case of carrying the first indication information by a sequence as an example, the network device configures 4 associated first transmission resources and 1 second transmission resource for the terminal device, that is, the second transmission resource is associated with 4 first transmission resources, and the 4 first transmission resources are respectively associated with 4 OFDM symbols, each of which can be used to transmit a sequence carrying the first indication information. The second transmission resource includes 4 logical resource unit starting positions, for example, the second transmission resource includes 4 starting positions of CCEs. The network device configures the first correspondence relationship between the OFDM symbol transmitting the first indication information and the logical resource unit starting position as one-to-one correspondence. The network device configures the first correspondence relationship between the OFDM symbol and the logical resource unit starting position on the second transmission resource as shown in Table 11.

[0406] Table 11

[0407] Exemplarily, the first information includes time domain resources corresponding to the first indication information, and the time domain resources include OFDM symbols. The network device configures four first transmission resources, and the sequences transmitted on the four first transmission resources are associated with four OFDM symbols. The starting positions of the logical resource units on the second transmission resource include the starting positions of four CCEs, for example. Different time domain resources (OFDM symbols) and different starting positions of logical resource units (starting positions of CCEs) have a first correspondence relationship. The starting position of a CCE is represented based on a CCE index. Optionally, when the first indication information is transmitted on the first transmission resource of the OFDM symbol 0, the CCE index on the second transmission resource is 0; when the first indication information is transmitted on the first transmission resource of the OFDM symbol 1, the CCE index on the second transmission resource is 1; when the first indication information is transmitted on the first transmission resource of the OFDM symbol 2, the CCE index on the second transmission resource is 2; and when the first indication information is transmitted on the first transmission resource of the OFDM symbol 3, the CCE index on the second transmission resource is 3.

[0408] It should be noted that the above Table 11 is only an exemplary description of the first correspondence relationship between the time domain resources and the starting positions of the logical resource units on the second transmission resource, and the method in the embodiments of the present application is not limited to the correspondence relationship in Table 11. In some embodiments, the correspondence relationship configured by the network includes only part of the content in the above table, such as only any two rows in the above table. In some embodiments, the correspondence relationship configured by the network includes K OFDM symbols, and the corresponding starting positions of the logical resource units are also K, where K is an integer greater than or equal to 1.

[0409] 2) One-to-many correspondence relationship between time domain resources and starting positions of logical resource units

[0410] Exemplarily, as shown in part (b) of FIG. 14, the network device configures four first transmission resources and one second transmission resource for the terminal device, that is, the second transmission resource is associated with the four first transmission resources, and the four first transmission resources are respectively associated with four OFDM symbols, each of which can be used to transmit a sequence carrying the first indication information. The second transmission resource includes four starting positions of logical resource units, for example, four starting positions of CCEs. The network device configures a one-to-many correspondence relationship between the OFDM symbols transmitting the first indication information and the starting positions of the logical resource units. The network device configures the first correspondence relationship between the OFDM symbols and the starting positions of the logical resource units on the second transmission resource as shown in Table 12.

[0411] Table 12

[0412] For example, the first information includes time domain resources corresponding to the first indication information, and the time domain resources include OFDM symbols. The first correspondence between the OFDM symbols and the starting positions of the logical resource units is a many-to-one correspondence, that is, a plurality of OFDM symbols correspond to one starting position of a logical resource unit (for example, a starting position of a CCE). Wherein, the starting position of the CCE is represented based on a CCE index. Optionally, when the first indication information is transmitted on the first transmission resource of OFDM symbols 0 and 1, the CCE index corresponding to the second transmission resource is 0; when the first indication information is transmitted on the first transmission resource of OFDM symbols 2 and 3, the CCE index corresponding to the second transmission resource is 2.

[0413] In some embodiments, when a plurality of time domain resources indicate the starting positions of the logical resource units on the second transmission resource, the transmission contents corresponding to the transmission resource sizes indicated by different time domain resources on the second transmission resource are different.

[0414] For example, when the OFDM symbol is 0, the DCI aggregation level indicated by the sequence carrying the first indication information is 1, the CCE index corresponding to the transmission resource of the DCI transmitted on the second transmission resource is 0, and the transmission resource size includes 1 CCE; when the OFDM symbol is 1, the DCI aggregation level indicated by the sequence carrying the first indication information is 2, the CCE index corresponding to the transmission resource of the DCI transmitted on the second transmission resource is 0, and the transmission resource size includes 2 CCEs.

[0415] It should be noted that the above table 12 is only an exemplary description of the first correspondence between the time domain resources and the starting positions of the logical resource units on the second transmission resource, and the method in the embodiments of the present application is not limited to the correspondence in table 12. In some embodiments, the correspondence configured by the network 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 correspondence configured by the network includes K OFDM symbols, and the corresponding starting positions of the logical resource units are also K, wherein K is an integer greater than or equal to 1.

[0416] 3) One-to-many correspondence between time domain resources and starting positions of logical resource units

[0417] For example, as shown in part (c) of FIG. 14, the network device configures, for the terminal device, 4 first transmission resources and 1 second transmission resource associated with the first indication information carried by the sequence, i.e., the second transmission resource is associated with the 4 first transmission resources, and the 4 first transmission resources are respectively associated with 4 OFDM symbols, which can be used to transmit the sequence carrying the first indication information. The second transmission resource includes 4 logical resource unit start positions, e.g., 4 CCE start positions. The network device configures a one-to-many correspondence between the OFDM symbol transmitting the first indication information and the logical resource unit start positions. The network device configures a one-to-many correspondence between the OFDM symbol and the logical resource unit start positions on the second transmission resource, as shown in Table 13.

[0418] Table 13

[0419] For example, the first information includes a time domain resource corresponding to the first indication information, and the time domain resource includes an OFDM symbol. The one-to-many correspondence is between the OFDM symbol and the frequency domain start position, i.e., one OFDM symbol corresponds to multiple logical resource unit start positions (e.g., multiple CCE start positions). Here, the CCE index represents the CCE start position. Alternatively, when the first transmission resource with the OFDM symbol 0 transmits the first indication information, the CCE index on the second transmission resource can be any one of CCE index 0, CCE index 1, CCE index 2, and CCE index 3.

[0420] Alternatively, the OFDM symbol determines the CCE index in combination with other information. For example, the other information can be an aggregation level, and the OFDM symbol determines the CCE index on the second transmission resource in combination with the DCI aggregation level indicated by the sequence carrying the first indication information. For example, when the OFDM symbol is 0, the DCI aggregation level indicated by the sequence carrying the first indication information is 4, the CCE index of the transmission resource corresponding to the DCI transmitted on the second transmission resource is 3, and the transmission resource size includes 4 CCE; when the OFDM symbol is 0, the DCI aggregation level indicated by the sequence carrying the first indication information is 2, the CCE index of the transmission resource corresponding to the DCI transmitted on the second transmission resource is 1, and the transmission resource size includes 2 CCE.

[0421] It should be noted that the above Table 13 is only an exemplary description of the first correspondence relationship between the time domain resource and the starting position of the logical resource unit on the second transmission resource. The method in the embodiments of the present application is not limited to the correspondence relationship in Table 13. In some embodiments, the correspondence 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 correspondence relationship configured by the network includes K OFDM symbols, and the corresponding starting positions of the logical resource units are also K, where K is an integer greater than or equal to 1.

[0422] 2. The time domain resource and the ending position of the resource have a correspondence relationship

[0423] In some embodiments, the network device configures a plurality of (at least two) first transmission resources corresponding to the second transmission resource, that is, the second transmission resource is associated with at least two first transmission resources in a group of transmission resources. Optionally, the first indication information transmitted on different first transmission resources is associated with different first information.

[0424] In some embodiments, the first information includes the time domain resource corresponding to the first indication information. Optionally, different time domain resources have a correspondence relationship with different resource ending positions, including at least one of the following cases: different time domain resources have a correspondence relationship with different time domain ending positions; different time domain resources have a correspondence relationship with different frequency domain ending positions; different time domain resources have a correspondence relationship with different logical resource unit ending positions.

[0425] 2.1 The time domain resource and the time domain ending position have a correspondence relationship

[0426] In some embodiments, different time domain resources correspond to different time domain ending positions, that is, based on the time domain resource corresponding to the first indication information, the time domain ending position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined, which can also be understood as, based on the sequence carrying the first indication information or the time domain resource corresponding to the at least one bit carrying the first indication information, the time domain ending position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined. Wherein, the time domain ending position refers to the ending position of the transmission content in the time domain dimension on the second transmission resource.

[0427] The correspondence relationship between the time domain resource and the time domain ending position has a similar implementation as the correspondence relationship between the time domain resource and the time domain starting position. For details, please refer to the related description in the above “1.1 The time domain resource and the time domain starting position have a correspondence relationship”. Here, it will not be repeated.

[0428] 2.2 The time domain resource and the frequency domain ending position have a correspondence relationship

[0429] In some embodiments, different time domain resources correspond to different frequency domain ending positions, that is, the frequency domain ending position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the time domain resource corresponding to the first indication information, which can also be understood as determining the frequency domain ending 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 sequence carrying the first indication information or the at least one bit carrying the first indication information. The frequency domain starting and ending positions refer to the ending position of the downlink transmission content on the second transmission resource in the frequency domain resource.

[0430] The corresponding relationship between the time domain resource and the frequency domain ending position is similar to the corresponding relationship between the time domain resource and the frequency domain starting position, and the detailed content can be referred to the related description in the above "1.2. The corresponding relationship between the time domain resource and the frequency domain starting position" and will not be repeated here.

[0431] 2.3. The corresponding relationship between the time domain resource and the logical resource unit ending position

[0432] In some embodiments, different time domain resources correspond to different logical resource unit ending positions, that is, the logical resource unit ending position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the time domain resource corresponding to the first indication information, which can also be understood as determining the logical resource unit ending 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 sequence carrying the first indication information or the at least one bit carrying the first indication information. The logical resource unit ending position refers to the ending position of the transmission content on the second transmission resource in the logical resource dimension.

[0433] The corresponding relationship between the time domain resource and the logical resource unit ending position is similar to the corresponding relationship between the time domain resource and the logical resource unit starting position, and the detailed content can be referred to the related description in the above "1.3. The corresponding relationship between the time domain resource and the logical resource unit starting position" and will not be repeated here.

[0434] 3. The corresponding relationship between the time domain resource and the resource size

[0435] In some embodiments, the network device configures a plurality of (at least two) first transmission resources corresponding to the second transmission resource, that is, the second transmission resource is associated with at least two first transmission resources in a group of transmission resources. Optionally, the first indication information transmitted on different first transmission resources is associated with different first information.

[0436] In some embodiments, the first information includes a time domain resource corresponding to the first indication information. Optionally, different time domain resources have a corresponding relationship with different resource sizes, including at least one of the following cases: different time domain resources have a corresponding relationship with different time domain unit quantities; different time domain resources have a corresponding relationship with different frequency domain unit quantities; different time domain resources have a corresponding relationship with different logical resource unit quantities.

[0437] 3.1 Time domain resources have a corresponding relationship with time domain unit quantities

[0438] In some embodiments, different time domain resources correspond to different time domain unit quantities, i.e., based on the time domain resource corresponding to the first indication information, the time domain unit quantity of the transmission resource of the downlink transmission content in the second transmission resource is determined, which can also be understood as, based on the sequence carrying the first indication information or the time domain resource corresponding to the at least one bit carrying the first indication information, the time domain unit quantity of the transmission resource of the downlink transmission content in the second transmission resource is determined. Wherein, the time domain unit quantity refers to the number of time units occupied by the transmission content on the second transmission resource in the time domain resource.

[0439] In some embodiments, the transmission resource of the second transmission resource is divided into multiple time units (i.e., time domain units). For example, the time domain starting position corresponds to the position of the first time unit, and the time domain unit quantity of the transmission content on the second transmission resource corresponds to one or more consecutive time units starting from the first time unit. Wherein, the unit of time unit is any one of the following: frame, subframe, slot, mini-slot, sub-slot, symbol, symbol group, unit based on other time domain units. It should be noted that the time domain unit is not limited to the above-mentioned units, and the units agreed by future communication protocols are also applicable to the present application.

[0440] In some embodiments, the network device configures at least two first transmission resources corresponding to the second transmission resource for the terminal device, i.e., the second transmission resource is associated with at least two first transmission resources. The first transmission resource includes multiple time domain resources that can be used to transmit the first indication information, and different time domain resources can indicate different time domain unit quantities.

[0441] For example, the network device configures 4 associated first transmission resources and 1 second transmission resource for the terminal device, i.e., the second transmission resource is associated with 4 first transmission resources, and the 4 first transmission resources are respectively associated with 4 OFDM symbols, each of which can be used to transmit the first indication information. The network device configures the first corresponding relationship between the OFDM symbol and the time domain unit quantity as shown in Table 14.

[0442] Table 14

[0443] For example, the first information includes time domain resources corresponding to the first indication information, and the time domain resources include OFDM symbols. For example, the network device configures four first transmission resources, and four OFDM symbols are associated with the sequence of the first indication information transmitted on the four first transmission resources. Different time domain resources (OFDM symbols) have a first correspondence relationship with different time domain unit quantities. Optionally, when the first indication information is transmitted on the first transmission resource with the OFDM symbol 0, the time domain unit quantity on the second transmission resource is the first quantity; when the first indication information is transmitted on the first transmission resource with the OFDM symbol 1, the time domain unit quantity on the second transmission resource is the second quantity; when the first indication information is transmitted on the first transmission resource with the OFDM symbol 2, the time domain unit quantity on the second transmission resource is the third quantity; and when the first indication information is transmitted on the first transmission resource with the OFDM symbol 3, the time domain unit quantity on the second transmission resource is the fourth quantity.

[0444] For example, when the OFDM symbol is 0, the time domain unit quantity is 1, that is, the number of time slots occupied by the transmission resource corresponding to the downlink transmission content on the second transmission resource is 1; when the OFDM symbol is 1, the time domain unit quantity is 2, that is, the number of time slots occupied by the transmission resource corresponding to the downlink transmission content on the second transmission resource is 2; when the OFDM symbol is 3, the time domain unit quantity is 3, that is, the number of time slots occupied by the transmission resource corresponding to the downlink transmission content on the second transmission resource is 3; and when the OFDM symbol is 3, the time domain unit quantity is 4, that is, the number of time slots occupied by the transmission resource corresponding to the downlink transmission content on the second transmission resource is 4.

[0445] It should be noted that the above table 14 is only an exemplary description of the first correspondence relationship between the time domain resources and the time domain unit quantity on the second transmission resource, and the method in the embodiments of the present application is not limited to the correspondence relationship in table 14. In some embodiments, the correspondence relationship configured by the network includes only part of the content in the above table, such as only any two rows in the above table; in some embodiments, the correspondence relationship configured by the network includes K OFDM symbols, and the corresponding time domain unit quantity is also K, where K is an integer greater than or equal to 1.

[0446] 3.2 Correspondence relationship between time domain resources and frequency domain unit quantities

[0447] In some embodiments, different time domain resources correspond to different frequency domain unit quantities, that is, the frequency domain unit quantity of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the time domain resource corresponding to the first indication information. It can also be understood that the frequency domain unit quantity of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the time domain resource corresponding to the sequence carrying the first indication information or the at least one bit carrying the first indication information. The frequency domain unit quantity refers to the number of frequency domain units occupied by the transmission content in the frequency domain resource on the second transmission resource.

[0448] In some embodiments, the transmission resource of the second transmission resource is divided into a plurality of frequency domain units. For example, the frequency domain starting position corresponds to the position of the first frequency domain unit, and the frequency domain unit quantity of the downlink transmission content on the second transmission resource corresponds to one or more continuous frequency domain units starting from the first frequency domain unit. The unit of the frequency domain unit is any one of the following: bandwidth, carrier, physical resource block (PRB), bandwidth part (BWP), subband, subchannel, subcarrier, and unit based on other frequency domain units. It should be noted that the frequency domain unit is not limited to the above-mentioned units, and units agreed by future communication protocols are also applicable to the present application.

[0449] In some embodiments, the network device configures at least two first transmission resources corresponding to the second transmission resource for the terminal device, that is, the second transmission resource is associated with at least two first transmission resources. The first transmission resource includes a plurality of time domain resources that can be used to transmit the first indication information, and different time domain resources can indicate different frequency domain unit quantities.

[0450] For example, the network device configures 4 associated first transmission resources and 1 second transmission resource for the terminal device, that is, the second transmission resource is associated with 4 first transmission resources, and the 4 first transmission resources are respectively associated with 4 OFDM symbols, each of which can be used to transmit the first indication information. The network device configures the first correspondence relationship between the OFDM symbol and the frequency domain unit quantity as shown in Table 15.

[0451] Table 15

[0452] Exemplarily, the first information includes time domain resources corresponding to the first indication information, and the time domain resources include OFDM symbols. Taking an example of that the network device configures 4 first transmission resources, and 4 OFDM symbols are associated with sequences of the first indication information transmitted on the 4 first transmission resources, there is a first correspondence relationship between different time domain resources (OFDM symbols) and different frequency domain unit quantities. Optionally, when the first indication information is transmitted on the first transmission resource with the OFDM symbol being 0, the frequency domain unit quantity on the second transmission resource corresponds to the first quantity; when the first indication information is transmitted on the first transmission resource with the OFDM symbol being 1, the frequency domain unit quantity on the second transmission resource corresponds to the second quantity; when the first indication information is transmitted on the first transmission resource with the OFDM symbol being 2, the frequency domain unit quantity on the second transmission resource corresponds to the third quantity; and when the first indication information is transmitted on the first transmission resource with the OFDM symbol being 3, the frequency domain unit quantity on the second transmission resource corresponds to the fourth quantity.

[0453] Taking an example of that the frequency domain unit is a subband, it is illustrated as follows. For example, when the OFDM symbol is 0, the frequency domain unit quantity is 1, that is, the time slot subband quantity occupied by the transmission resource corresponding to the downlink transmission content on the second transmission resource is 1; when the OFDM symbol is 1, the frequency domain unit quantity is 2, that is, the subband quantity occupied by the transmission resource corresponding to the downlink transmission content on the second transmission resource is 2; when the OFDM symbol is 3, the time domain unit quantity is 4, that is, the subband quantity occupied by the transmission resource corresponding to the downlink transmission content on the second transmission resource is 4; and when the OFDM symbol is 3, the time domain unit quantity is 5, that is, the subband quantity occupied by the transmission resource corresponding to the downlink transmission content on the second transmission resource is 5.

[0454] It should be noted that the above table 15 is only an exemplary illustration of the first correspondence relationship between the time domain resource and the frequency domain unit quantity on the second transmission resource, and the method in the embodiments of the present application is not limited to the correspondence relationship in the table 15. In some embodiments, the correspondence relationship configured by the network includes only part of the content in the above table, such as only any 2 rows in the above table; in some embodiments, the correspondence relationship configured by the network includes K OFDM symbols, and the corresponding frequency domain unit quantity is also K, where K is an integer greater than or equal to 1.

[0455] 3.3 Correspondence relationship between time domain resource and logical resource unit quantity

[0456] In some embodiments, different time domain resources correspond to different logical resource unit quantities, that is, the logical resource unit quantity of the transmission resource of the downlink transmission content in the second transmission resource is determined based on the time domain resource corresponding to the first indication information. It can also be understood that, based on the time domain resource corresponding to the sequence carrying the first indication information or the at least one bit carrying the first indication information, the logical resource unit quantity of the transmission resource of the downlink transmission content in the second transmission resource is determined. Wherein, the logical resource unit quantity refers to the number of logical resource units occupied by the downlink transmission content on the logical resource in the second transmission resource.

[0457] In some embodiments, the transmission resource of the second transmission resource is divided into a plurality of logical resource units. For example, the logical resource unit starting position corresponds to the position of the first logical resource unit, and the logical resource unit quantity of the downlink transmission content on the second transmission resource corresponds to one or more continuous logical resource units starting from the first logical resource unit. Wherein, the unit of the logical resource unit is any one of the following: resource unit group (REG), control channel unit (CCE), virtual resource block (VRB), unit based on other logical resource units. It should be noted that the logical resource unit is not limited to the above-mentioned units, and units agreed by future communication protocols are also applicable to the present application.

[0458] In some embodiments, the network device configures at least two first transmission resources corresponding to the second transmission resource for the terminal device, that is, the second transmission resource is associated with at least two first transmission resources. The first transmission resource includes a plurality of time domain resources that can be used to transmit the first indication information, and different time domain resources can indicate different logical resource unit quantities.

[0459] For example, the network device configures 4 associated first transmission resources and 1 second transmission resource for the terminal device, that is, the second transmission resource is associated with 4 first transmission resources, and the 4 first transmission resources are respectively associated with 4 OFDM symbols, each of which can be used to transmit the first indication information. The network device configures the first correspondence relationship between the OFDM symbol and the logical resource unit quantity as shown in Table 16.

[0460] Table 16

[0461] Exemplarily, the first information includes time domain resources corresponding to the first indication information, and the time domain resources include OFDM symbols. Taking an example of that the network device configures 4 first transmission resources, and 4 OFDM symbols are associated with the sequence of the first indication information transmitted on the 4 first transmission resources, there is a first correspondence relationship between different time domain resources (OFDM symbols) and different logical resource unit quantities. Optionally, when the first indication information is transmitted on the first transmission resource of the OFDM symbol 0, the quantity of the logical resource units on the second transmission resource corresponds to the first quantity; when the first indication information is transmitted on the first transmission resource of the OFDM symbol 1, the quantity of the logical resource units on the second transmission resource corresponds to the second quantity; when the first indication information is transmitted on the first transmission resource of the OFDM symbol 2, the quantity of the logical resource units on the second transmission resource corresponds to the third quantity; and when the first indication information is transmitted on the first transmission resource of the OFDM symbol 3, the quantity of the logical resource units on the second transmission resource corresponds to the fourth quantity.

[0462] Taking the logical resource unit as the CCE as an example, for example, when the OFDM symbol is 0, the quantity of the logical resource units is 1, that is, the quantity of the CCEs occupied by the transmission resource corresponding to the downlink transmission content on the second transmission resource is 1; when the OFDM symbol is 1, the quantity of the logical resource units is 2, that is, the quantity of the CCEs occupied by the transmission resource corresponding to the downlink transmission content on the second transmission resource is 2; when the OFDM symbol is 3, the quantity of the logical resource units is 4, that is, the quantity of the CCEs occupied by the transmission resource corresponding to the downlink transmission content on the second transmission resource is 4; and when the OFDM symbol is 3, the quantity of the logical resource units is 8, that is, the quantity of the CCEs occupied by the transmission resource corresponding to the downlink transmission content on the second transmission resource is 8.

[0463] It should be noted that the above table 16 is only an exemplary description of the first correspondence relationship between the time domain resources and the quantity of the logical resource units on the second transmission resource, and the method in the embodiments of the present application is not limited to the correspondence relationship in the table 16. In some embodiments, the correspondence relationship configured by the network includes only part of the contents in the above table, such as only any 2 rows in the above table; in some embodiments, the correspondence relationship configured by the network includes K OFDM symbols, and the quantity of the logical resource units corresponding to the K OFDM symbols is also K, where K is an integer greater than or equal to 1.

[0473] In some embodiments, the second correspondence relationship comprises a one-to-one correspondence, i.e. one frequency domain resource corresponds to one resource location; or the second correspondence relationship comprises a many-to-one correspondence, i.e. multiple frequency domain resources correspond to one resource location; or the second correspondence relationship comprises a one-to-many correspondence, i.e. one frequency domain resource corresponds to multiple resource locations. The frequency domain resource is the frequency domain resource corresponding to the first indication information, and the resource location is the location of the transmission resource corresponding to the downlink transmission content in the second transmission resource.

It can be understood that the time domain starting position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the frequency domain resource corresponding to the first indication information, and it can also be understood that the time domain starting position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the frequency domain resource corresponding to the sequence or at least one bit carrying the first indication information. Wherein, the time domain starting position refers to the starting position of the transmission content in the time domain dimension on the second transmission resource.

[0482] In some embodiments, the network device configures N first transmission resources corresponding to one second transmission resource for the terminal device, that is, one second transmission resource is associated with N first transmission resources, and N is a positive integer greater than 1.

The second transmission resource includes M time domain starting positions, and the second correspondence relationship between the N frequency domain resources and the M time domain starting positions is one-to-one correspondence, or many-to-one correspondence, or one-to-many correspondence.

[0483] For example, the second correspondence relationship between the frequency domain resource corresponding to the first indication information and the time domain starting position on the second transmission resource is one-to-one correspondence.

The second transmission resource includes M frequency domain starting positions, and the second correspondence relationship between the N frequency domain resources and the M frequency domain starting positions is a one-to-one correspondence relationship, or a many-to-one correspondence relationship, or a one-to-many correspondence relationship.

[0492] For example, the second correspondence relationship between the frequency domain resource corresponding to the first indication information and the frequency domain starting position on the second transmission resource is one-to-one correspondence. For example, as shown in part (b) of FIG. 15, the network device configures 4 first transmission resources and 1 second transmission resource for the terminal device, i.e., the second transmission resource is associated with 4 first transmission resources, and the 4 first transmission resources are respectively associated with 4 frequency domain units, such as subbands, each of which can be used to transmit a sequence carrying the first indication information. The second transmission resource includes 4 frequency domain starting positions.

[0498] In some embodiments, the first transmission resource is used to transmit the first indication information, and the different frequency domain starting positions corresponding to the first indication information have a second correspondence relationship with the logical resource unit starting positions on the second transmission resource.

[0499] In some embodiments, different frequency domain resources correspond to different logical resource unit starting positions, i.e., different frequency domain starting positions corresponding to the first indication information correspond to different logical resource unit starting positions on the second transmission resource. It can be understood that the logical resource unit starting position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the frequency domain resource corresponding to the first indication information, or it can be understood that the logical resource unit starting position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the frequency domain resource corresponding to the sequence or at least one bit carrying the first indication information. Wherein, the logical resource unit starting position refers to the starting position of the transmission content on the second transmission resource in the logical resource dimension.

[0508] 2. The frequency domain resource corresponding to the first indication information is represented by a frequency domain offset of the frequency domain resource

[0509] In some embodiments, the frequency domain resource corresponding to the first indication information is represented by a frequency domain offset of the frequency domain resource, and different frequency domain offsets and different resource positions on the second transmission resource have a second correspondence relationship, i.e., different frequency domain offsets corresponding to the first indication information and different resource starting positions on the second transmission resource have a second correspondence relationship; or different frequency domain offsets corresponding to the first indication information and different resource ending positions on the second transmission resource have a second correspondence relationship; or different frequency domain offsets corresponding to the first indication information and different resource sizes on the second transmission resource have a second correspondence relationship.

[0510] In some embodiments, the first indication information is mapped to the first transmission resource in the form of a comb, and the frequency domain offset is used to indicate the offset of the comb resource occupied by the first indication information in the first transmission resource.

[0511] In some embodiments, the first transmission resource can be referred to as a first comb-shaped resource. Optionally, the first transmission resource includes n frequency domain units, and the n frequency domain units in the first transmission resource are arranged in a comb shape.

[0512] In the following, the resource position is mainly taken as an example for introduction, which includes a resource start position. Optionally, the resource start position includes at least one of a time domain start position, a frequency domain start position, and a logical resource unit start position.

[0513] 2.1 The second correspondence relationship between the different frequency domain offsets corresponding to the first indication information and the time domain start positions on the second transmission resource

[0514] In some embodiments, the first transmission resource is used to transmit the first indication information, and the different frequency domain offsets corresponding to the first indication information have the second correspondence relationship with the time domain start positions on the second transmission resource.

[0515] In some embodiments, different frequency domain offsets correspond to different time domain start positions, i.e., the time domain start position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the frequency domain offset.

[0516] In some embodiments, the network device configures N first transmission resources corresponding to one second transmission resource for the terminal device, i.e., one second transmission resource is associated with N first transmission resources, and N is a positive integer greater than 1. The first indication information transmitted on the N first transmission resources is associated with N frequency domain offsets. The second transmission resource includes M time domain start positions, and the second correspondence relationship between the N frequency domain offsets and the M time domain start positions is one-to-one correspondence, or many-to-one correspondence, or one-to-many correspondence.

[0517] In some embodiments, each of the N first transmission resources can be considered as a comb-shaped frequency domain resource; or each first transmission resource can be considered as a group of frequency domain resources arranged in a comb shape. Optionally, each first transmission resource can be considered as a group of frequency domain resources arranged at equal intervals, for example, the interval between two adjacent frequency domain resources in each first transmission resource is 4 frequency domain units, and one of every 4 frequency domain units is used to map a sequence carrying the first indication information.

[0518] For example, the second correspondence relationship between the frequency domain offset corresponding to the first indication information and the time domain starting position on the second transmission resource is a one-to-one correspondence. For example, as shown in FIG. 16, the network device configures 4 first transmission resources and 1 second transmission resource for the terminal device by taking a sequence carrying the first indication information as an example, that is, the second transmission resource is associated with 4 first transmission resources, and the 4 first transmission resources are comb-shaped frequency domain resources, each of which corresponds to a different frequency domain offset. For example, taking the lowest frequency domain position as a reference point, 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 comb-shaped frequency domain resource can be used to transmit a sequence carrying the first indication information. The second transmission resource includes 4 time domain starting positions. The network device configures the second correspondence relationship between the frequency domain offset and the time domain starting position as a one-to-one correspondence. The network device configures the second correspondence relationship between the frequency domain offset corresponding to the first indication information and the time domain starting position on the second transmission resource as shown in Table 20.

For example, the network device configures 4 first transmission resources, the 4 first transmission resources are comb-shaped frequency domain resources, each of which corresponds to a different frequency domain offset, the 4 first transmission resources are associated with 4 frequency domain offsets, and the second transmission resource includes 4 time domain starting positions. Different frequency domain resources (frequency domain offsets) and different time domain starting positions have a second correspondence relationship. Alternatively, when the first indication information is transmitted on the first transmission resource with a frequency domain offset of 0, the time domain starting position A on the second transmission resource is used as a corresponding position; when the first indication information is transmitted on the first transmission resource with a frequency domain offset of 1, the time domain starting position B on the second transmission resource is used as a corresponding position; when the first indication information is transmitted on the first transmission resource with a frequency domain offset of 2, the time domain starting position C on the second transmission resource is used as a corresponding position; and when the first indication information is transmitted on the first transmission resource with a frequency domain offset of 3, the time domain starting position D on the second transmission resource is used as a corresponding position.

[0529] In some embodiments, the resource location includes a resource end 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.

[0531] 3. The frequency domain resource size of the frequency domain resource based on the frequency domain resource represents the frequency domain resource corresponding to the first indication information

[0532] In some embodiments, the frequency domain resource size (or sequence length) of the frequency domain resource based on the first indication information represents the frequency domain resource corresponding to the first indication information. Different frequency domain resource sizes and different resource locations on the second transmission resource have a second correspondence relationship, that is, different frequency domain resource sizes corresponding to the first indication information and different resource start locations on the second transmission resource have a second correspondence relationship. Alternatively, different frequency domain resource sizes and different resource end locations on the second transmission resource have a second correspondence relationship. Alternatively, different frequency domain resource sizes and different resource sizes on the second transmission resource have a second correspondence relationship.

[0533] Next, mainly taking the resource location including the resource start location as an example for introduction. Alternatively, the resource start location includes at least one of the time domain start location, the frequency domain start location, and the logical resource unit start location.

[0534] 3.1 The frequency domain resource size corresponding to the first indication information and the frequency domain start location on the second transmission resource have a second correspondence relationship

[0535] In some embodiments, the first transmission resource is used to transmit the first indication information. Different frequency domain resource sizes corresponding to the first indication information and the frequency domain start location on the second transmission resource have a second correspondence relationship, or alternatively, different sequence lengths on the first transmission resource and the frequency domain start location on the second transmission resource have a second correspondence relationship.

[0536] In some embodiments, different frequency domain resource sizes correspond to different frequency domain starting positions, i.e., different frequency domain resource sizes on the first transmission resource correspond to different frequency domain starting positions on the second transmission resource. It can be understood that the frequency domain starting position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the frequency domain resource size corresponding to the first indication information, or it can be understood that the frequency domain starting position of the transmission resource corresponding to the downlink transmission content in the second transmission resource is determined based on the frequency domain resource size corresponding to the sequence or at least one bit carrying the first indication information. The frequency domain starting position refers to the starting position of the transmission content in the frequency domain dimension on the second transmission resource.

[0537] In some embodiments, the network device configures N first transmission resources corresponding to one second transmission resource for the terminal device, i.e., one second transmission resource is associated with N first transmission resources, and N is a positive integer greater than 1. The sequence transmitted on the N first transmission resources is associated with N frequency domain resources. Each of the N frequency domain resources can be used to transmit the sequence carrying the first indication information. The second transmission resource includes M frequency domain starting positions, and the second correspondence between the N frequency domain resources and the M frequency domain starting positions is one-to-one correspondence, or many-to-one correspondence, or one-to-many correspondence.

[0538] For example, in combination with reference to FIG. 17, the network device configures 4 associated first transmission resources and 1 second transmission resource for the terminal device, i.e., the second transmission resource is associated with 4 first transmission resources, the sequence transmitted on the 4 first transmission resources is associated with 4 frequency domain units, e.g., subbands, and the sequence carrying the first indication information can occupy different numbers of subbands, e.g., 1 subband, 2 subbands, and 4 subbands. Optionally, the longer the length of the sequence carrying the first indication information, the more subbands it occupies. The second transmission resource includes 4 frequency domain starting positions. As shown in part (a) of FIG. 17, the frequency domain resource size for transmitting the first indication information is 1 subband, as shown in part (b) of FIG. 17, the frequency domain resource size for transmitting the first indication information is 2 subbands, and as shown in part (c) of FIG. 17, the frequency domain resource size for transmitting the first indication information is 4 subbands. The network device configures the second correspondence between the frequency domain resource size corresponding to the first indication information and the frequency domain starting position on the second transmission resource as shown in Table 21.

[0539] Table 21

[0540] For example, the first information includes a frequency domain resource corresponding to the first indication information, the frequency domain resource includes a sub-band, and a sequence carrying the first indication information can occupy different numbers of sub-bands. For example, the network device configures four first transmission resources, and a sequence transmitted on the four first transmission resources is associated with four sub-bands. For example, the second transmission resource includes four frequency domain starting positions, and different frequency domain resource sizes and different frequency domain starting positions have a second correspondence relationship. Alternatively, when the first indication information is transmitted on a first transmission resource with a frequency domain resource size of 1, that is, the sequence carrying the first indication information can occupy one sub-band, the first indication information can be transmitted based on any one of sub-band 0 to sub-band 3, corresponding to the frequency domain starting position d on the second transmission resource; when the first indication information is transmitted on a first transmission resource with a frequency domain resource size of 2, that is, the sequence carrying the first indication information can occupy two sub-bands, the first indication information can be transmitted based on sub-band 0 and sub-band 1, or sub-band 1 and sub-band 2, or sub-band 2 and sub-band 3, corresponding to the frequency domain starting position c on the second transmission resource; when the first indication information is transmitted on a first transmission resource with a frequency domain resource size of 4, the first indication information can be transmitted based on sub-band 0, sub-band 1, sub-band 2, and sub-band 3, corresponding to the frequency domain starting position a on the second transmission resource.

[0541] It should be noted that the above Table 21 is only an exemplary description of the second correspondence relationship between the frequency domain resource (frequency domain resource size) corresponding to the first indication information and the time domain starting position on the second transmission resource, and the method in the embodiments of the present application is not limited to the correspondence relationship in Table 21. In some embodiments, the correspondence relationship configured by the network includes only part of the content in the above table, such as only any two rows in the above table; in some embodiments, the frequency domain resource size included in the correspondence relationship configured by the network is K, and the corresponding frequency domain starting position is also K, where K is an integer greater than or equal to 1.

[0555] 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 transmitted on different first transmission resources is associated with different first information, and the first information has a corresponding relationship with different resource positions on the second transmission resource. In the embodiments of the present application, the at least two first transmission resources correspond to different time domain resources, or different frequency domain resources, or different code domain resources.

[0556] In some embodiments, the first information includes a first parameter corresponding to a sequence carrying the first indication information, sequences transmitted on different first transmission resources are associated with different first parameters, or sequences transmitted on different first transmission resources are associated with different values of the first parameter. It can also be understood that at least two first transmission resources are associated with different first parameters or different values of the first parameter, or a part of the first transmission resources are associated with different first parameters or different values of the first parameter. The present application does not limit this.

[0558] In some embodiments, the third correspondence relationship includes a correspondence relationship between the first parameter and the resource location, which can be understood as including a correspondence relationship between the first parameter and a resource start location, or a correspondence relationship between the first parameter and a resource end location, or a correspondence relationship between the first parameter and a resource size.

[0559] In some embodiments, the third correspondence relationship is determined based on protocol pre-defined information or network configuration information.

[0560] In some embodiments, the third correspondence relationship includes a one-to-one correspondence relationship, i.e., a first parameter corresponding to one sequence corresponds to one resource location; or the third correspondence relationship includes a many-to-one correspondence relationship, i.e., a first parameter corresponding to multiple sequences corresponds to one resource location; or the third correspondence relationship includes a one-to-many correspondence relationship, i.e., a first parameter corresponding to one sequence corresponds to resource locations on multiple second transmission resources. The resource location is the location of the transmission resource corresponding to the downlink transmission content in the second transmission resource.

[0561] In some embodiments, the network device configures a sequence for carrying the first indication information, the sequence is generated or determined based on a first parameter, and the network device configures a third correspondence relationship between the first parameter and the resource location.

[0562] In the following, the resource location includes a resource start location as an example. Optionally, the resource start location includes at least one of a time domain start location, a frequency domain start location, and a logical resource unit start location.

[0563] 1. The first parameter has a third correspondence relationship with the resource start location

[0564] In some embodiments, the network device configures at least two first transmission resources to correspond to the second transmission resource, i.e., the second transmission resource is associated with the at least two first transmission resources. Optionally, the first indication information transmitted on different first transmission resources is associated with different first information.

[0567] For example, as shown in part (a) of FIG. 18, the network device configures 4 associated first transmission resources and 1 second transmission resource for the terminal device, i.e., the second transmission resource is associated with the 4 first transmission resources. The sequence transmitted on each first transmission resource is determined based on different values of the first parameter, and the sequence transmitted on the 4 first transmission resources is determined based on 4 values of the first parameter. 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 resources. The second transmission resource includes 4 time domain starting positions. The network device configures a third corresponding relationship between the first parameter and the time domain starting positions on the second transmission resource, as shown in Table 22.

[0568] Table 22

Taking an example in which the network device configures 4 first transmission resources, the sequence transmitted on the 4 first transmission resources is associated with 4 sequences, and the time domain starting positions on the second transmission resource include 4 time domain starting positions, different values of the first parameter have a third corresponding relationship with different 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.

[0570] It should be noted that the above Table 22 is only an exemplary illustration of the third correspondence between the first parameter and the time-domain starting position on the second transmission resource, and the method in the embodiments of the present application is not limited to the correspondence in Table 22. In some embodiments, the correspondence configured by the network includes only part of the content in the above table, such as only any 2 rows in the above table; in some embodiments, the correspondence configured by the network includes K values of the first parameter, and the corresponding time-domain starting positions are also K, where K is an integer greater than or equal to 1.

[0571] In some embodiments, the values of the first parameter and the time-domain starting positions on the second transmission resource are one-to-one correspondence, or the values of the first parameter and the time-domain starting positions on the second transmission resource are many-to-one correspondence, or the values of the first parameter and the time-domain starting positions on the second transmission resource are one-to-many correspondence, which will not be repeated here.

[0573] In some embodiments, the network device configures at least two first transmission resources corresponding to the second transmission resource, that is, the second transmission resource is associated with at least two first transmission resources, and the sequences transmitted on different first transmission resources are associated with different first parameters. Optionally, different first parameters and different frequency-domain starting positions have a third correspondence.

[0574] For example, in combination with reference to FIG. 18, as shown in part (b) of FIG. 18, the network device configures the terminal device with 4 associated first transmission resources and 1 second transmission resource, 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 values of the first parameter, and the sequences transmitted on the 4 first transmission resources are determined based on 4 values of the first parameter. 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 frequency-domain starting positions. The network device configures the third correspondence between the first parameter and the frequency-domain starting position on the second transmission resource as shown in Table 23.

[0575] Table 23

[0576] For example, the first information includes a first parameter corresponding to the sequence. The network device configures four first transmission resources, and the sequences transmitted on the four first transmission resources are associated with four sequences. The four frequency domain starting positions on the second transmission resource are taken as an example. The third correspondence relationship is between the values of different first parameters and different frequency domain starting positions. Optionally, when the value of the first parameter is a first value, the frequency domain starting position a on the second transmission resource is corresponding; when the value of the first parameter is a second value, the frequency domain starting position b on the second transmission resource is corresponding; when the value of the first parameter is a third value, the frequency domain starting position c on the second transmission resource is corresponding; and when the value of the first parameter is a fourth value, the frequency domain starting position d on the second transmission resource is corresponding.

[0577] It should be noted that the above Table 23 is only an exemplary description of the third correspondence relationship between the first parameter and the frequency domain starting position on the second transmission resource. The method in the embodiments of the present application is not limited to the correspondence relationship in Table 23. In some embodiments, the correspondence relationship configured by the network includes only part of the content in the above table, such as only any two rows in the above table. In some embodiments, the value of the first parameter included in the correspondence relationship configured by the network is K, and the corresponding frequency domain starting position is also K, where K is an integer greater than or equal to 1.

[0580] In some embodiments, the network device configures at least two first transmission resources corresponding to the second transmission resource, that is, the second transmission resource is associated with at least two first transmission resources, and the sequences transmitted on different first transmission resources are associated with different first parameters. Optionally, the third correspondence relationship is between different first parameters and different logical resource unit starting positions.

[0581] In some embodiments, the sequence carrying the first indication information is a pseudo-random sequence, and the pseudo-random sequence is determined based on a value of a parameter Cinit. Optionally, the network configures four values of Cinit, for example, 17, 53, 127, and 131, and four sequences can be determined based on the four values. The second transmission resource includes four logical resource unit starting positions, for example, the second transmission resource includes four CCE starting positions. For example, the four sequences are used to indicate different aggregation levels of 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 the 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 between the value of the first parameter and the logical resource unit starting position, that is, the network configures a correspondence between the value of Cinit and the CCE starting position for transmitting the DCI on the second transmission resource, as shown in Table 24.

[0582] Table 24

[0583] For example, the first information includes a first parameter corresponding to a sequence. The network device configures four first transmission resources for the terminal device, that is, 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 sequence transmitted on the four first transmission resources is determined based on four first parameters. Wherein, the CCE index represents 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 index 0 to index 7, respectively. As shown in Table 24 above, when the value of the first parameter is 17 (corresponding to the first sequence), the aggregation level of the DCI indicated thereby is 1, that is, 1 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 thereby is 2, that is, 2 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 index 4 or 5; when the value of the first parameter is 127 (corresponding to the third sequence), the aggregation level of the DCI indicated thereby is 4, that is, 4 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 index 4, 5, 6, and 7; when the value of the first parameter is 151 (corresponding to the fourth sequence), the aggregation level of the DCI indicated thereby is 8, that is, 8 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 continuous 8 CCEs starting from index 0.

[0584] It should be noted that the above Table 24 is only an exemplary description of the third correspondence between the first parameter and the starting position of the logical resource unit (CCE index) on the second transmission resource, and the method in the embodiments of the present application is not limited to the correspondence in Table 24. In some embodiments, the correspondence configured by the network includes only part of the above table, such as only any 2 rows in the above table; in some embodiments, the first parameter included in the correspondence configured by the network is K, and the corresponding starting position of the logical resource unit is also K, where K is an integer greater than or equal to 1.
