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

[0071] Physical Downlink Control CHannel (PDCCH) detection:

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

[0073] Table 1

[0074] · Terminal device complexity optimization:

[0075] A terminal device can be referred to as a terminal, and the terminal design in NR Release 15 / Release 16 (R15 / R16) supports a very high peak rate. Therefore, the terminal has a high capability requirement. The LTE standard defines a maximum single-carrier bandwidth of 20 MHz, and a larger bandwidth is achieved by multi-carrier aggregation. The maximum carrier bandwidth of 5G NR in the sub-6 GHz frequency band is ultimately defined as 100 MHz, which is 5 times that of LTE, and the maximum carrier bandwidth in the millimeter wave frequency band is 400 MHz. The required multiple-input multiple-output (MIMO) antenna size of NR is further increased. The terminal antenna reference configuration of LTE is one transmit and two receives, while NR R15 requires two transmits and four receives at a frequency of 2500 MHz or above. NR R15 / R16 also does not support half duplex, and requires data processing for all slots of uplink and downlink.

[0076] However, some application scenarios of NR do not require such high processing capability in terms of processing capacity and speed, including Internet of Things, industrial automation and wearable device applications. In these scenarios, the communication hardware is required to have a lower volume and power consumption, and the lightweight capability requirement is a feature of such terminals. Based on such considerations, the NR R17 study introduces a reduced-capability compact terminal standard.

[0077] The compact terminal standard reduces some of the mandatory capabilities of NR R15 / R16. Corresponding terminal function groups are defined for such capabilities. The compact terminal standard further optimizes terminal identification, access procedures and power consumption for measurements to adapt to related application scenarios. The design of such compact terminals 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 also be achieved.

[0078] In the related art, a terminal device can only detect a PDCCH in a search space configured by a network device, and the terminal device judges whether to receive downlink data or transmit uplink data by detecting whether the network device transmits the PDCCH. However, the terminal device consumes energy by detecting the PDCCH, and continuously detecting the PDCCH is not conducive to energy saving and consumption reduction of the terminal device. In order to solve the above problem, an embodiment of the present application provides a transmission method, and FIG. 2 shows a flowchart of the transmission method provided by an exemplary embodiment of the present application. The method is executed by a terminal device, and the method comprises the following steps:

[0079] Step 210: Obtain first indication information on a first transmission resource in a set of transmission resources.

[0080] The set of transmission resources includes the first transmission resource and other transmission resources, the other transmission resources are at least one transmission resource in the set of transmission resources except the first transmission resource, the first indication information is used to indicate transmission content on the other transmission resources, and at least two transmission resources in the set of transmission resources have a corresponding relationship.

[0081] In some embodiments, the first indication information is indicated in the form of a sequence, or it is understood that the first indication information is carried by a sequence. The sequence type used to carry the first indication information includes at least one of a complex (vector) sequence and a real sequence.

[0082] The complex (vector) sequence includes at least one of the following: a constant envelope zero autocorrelation (CAZAC) sequence; a ZC (Zaddoff Chu) sequence; and the real sequence includes at least one of the following: a pseudo-random sequence; a Gold sequence; an m sequence; and a Hadamard sequence.

[0083] In some embodiments, the first indication information is carried by a first sequence, and a length of the first sequence is determined based on at least one of the following: pre-defined information based on a protocol; configuration information sent by a network; frequency domain resource size included in the first transmission resource.

[0084] For example, the first transmission resource includes K subcarriers or resource elements (REs), and the sequence length L is a largest prime number less than or equal to K, or a largest prime number less than or equal to (K / A), where A is a pre-defined positive integer, for example, A = 2 or 4.

[0085] 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.

[0086] In some embodiments, the first indication information is carried by first information associated with the first sequence, and the first information is determined based on at least one of the following: length corresponding to the first sequence; frequency domain resource information corresponding to the first sequence; time domain resource information corresponding to the first sequence; sequence index corresponding to the first sequence; sequence group index corresponding to the first sequence.

[0087] For example, different lengths corresponding to the first sequence respectively correspond to different values or different states or different sequences, thereby indicating different transmission contents on the other transmission resources.

[0088] For example, different frequency domain resources corresponding to the first sequence respectively correspond to different values or different states or different sequences, thereby indicating different transmission contents on the other transmission resources.

[0089] For example, different time domain resources corresponding to the first sequence respectively correspond to different values or different states or different sequences, thereby indicating different transmission contents on the other transmission resources.

[0090] For example, different sequence groups corresponding to the first sequence respectively correspond to different values or different states or different sequences, thereby indicating different transmission contents on the other transmission resources.

[0091] In some embodiments, the transmission content on the other transmission resources is determined based on different first information associated with the first indication information. It can be understood that the transmission content on the other transmission resources is indicated based on different first information associated with the first indication information.

[0092] 1.1 Optionally, the following five different indication methods can be used to indicate the transmission content on the other transmission resources.

[0093] Indication mode one: indicating the transmission content on the other transmission resource based on the length corresponding to the first sequence;

[0094] Indication mode two: indicating the transmission content on the other transmission resource based on the frequency domain resource corresponding to the first sequence;

[0095] Indication mode three: indicating the transmission content on the other transmission resource based on the time domain resource corresponding to the first sequence;

[0096] Indication mode four: indicating the transmission content on the other transmission resource based on the sequence index corresponding to the first sequence;

[0097] Indication mode five: indicating the transmission content on the other transmission resource based on the sequence group index corresponding to the first sequence.

[0098] In some embodiments, the other transmission resource includes at least one of a second transmission resource and a third transmission resource, and the transmission content on the other transmission resource includes at least one of:

[0099] 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; no transmission on the third transmission resource; transmission of feedback information on the third transmission resource; transmission of first uplink data on the third transmission resource; transmission of feedback information and first uplink data on the third transmission resource.

[0100] 1.1.1 For indication mode one: indicating the transmission content on the other transmission resource based on the length corresponding to the first sequence.

[0101] There is an association or correspondence between the sequence length and the transmission content, which is determined based on protocol pre-defined information or network configuration information.

[0102] For example, based on the length corresponding to the first sequence to indicate one transmission content on the other 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 are not limited by the present application.

[0103] For another example, based on the length corresponding to the first sequence to indicate multiple (two or more) transmission contents on the other transmission resource, length index value 9 indicates no transmission on the second transmission resource and no transmission on the third transmission resource; length index value 10 indicates transmission of first downlink data on the second transmission resource and transmission of feedback information on the third transmission resource, etc., which are not limited by the present application.

[0104] 1.1.2 For the second indication mode: based on the frequency domain resource corresponding to the first sequence to indicate the transmission content on other transmission resources.

[0105] There is a correlation or correspondence between the frequency domain resource corresponding to the sequence and the transmission content, which is determined based on protocol pre-defined information or network configuration information.

[0106] The frequency domain resource corresponding to the first sequence can be understood as the frequency domain resource corresponding to the first transmission resource where the first sequence is located; or, can be understood as the frequency domain resource corresponding to the first sequence in the first transmission resource; or, can be understood as the frequency domain resource carrying the first sequence in the first transmission resource.

[0107] For example, based on the frequency domain resource corresponding to the first sequence to indicate one transmission content on other transmission resources, the frequency domain resource index value 1 indicates no transmission on the second transmission resource, the frequency domain resource index value 2 indicates transmission of DCI or PDCCH on the second transmission resource, and the frequency domain resource index value 3 indicates transmission of the first downlink data on the second transmission resource, etc., which are not limited by the present application.

[0108] For another example, based on the frequency domain resource corresponding to the first sequence to indicate multiple (two or more) transmission contents on other transmission resources, the frequency domain resource index value 9 indicates no transmission on the second transmission resource and no transmission on the third transmission resource; the frequency domain resource index value 10 indicates transmission of the first downlink data on the second transmission resource and transmission of feedback information on the third transmission resource, etc., which are not limited by the present application.

[0109] 1.1.3 For the third indication mode: based on the time domain resource corresponding to the first sequence to indicate the transmission content on other transmission resources.

[0110] There is a correlation or correspondence between the time domain resource corresponding to the sequence and the transmission content, which is determined based on protocol pre-defined information or network configuration information.

[0111] The time domain resource corresponding to the first sequence can be understood as the time domain resource corresponding to the first transmission resource where the first sequence is located; or, can be understood as the time domain resource corresponding to the first sequence in the first transmission resource; or, can be understood as the time domain resource carrying the first sequence in the first transmission resource.

[0112] For example, based on the time domain resource corresponding to the first sequence to indicate one transmission content on other transmission resources, the time domain resource index value 1 indicates no transmission on the second transmission resource, the time domain resource index value 2 indicates transmission of DCI or PDCCH on the second transmission resource, and the time domain resource index value 3 indicates transmission of the first downlink data on the second transmission resource, etc., which are not limited by the present application.

[0113] For example, based on the time domain resource corresponding to the first sequence, one transmission content on the other transmission resource is indicated, and the time domain resource index value 1 indicates that no transmission is performed 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.

[0114] 1.1.4 For the indication mode four: the transmission content on the other transmission resource is indicated based on the sequence index corresponding to the first sequence.

[0115] The sequence index corresponding to the sequence and the transmission content have a corresponding relationship or an association relationship, and the corresponding relationship or the association relationship is determined based on the protocol pre-defined information or the network configuration information.

[0116] For example, based on the sequence index corresponding to the first sequence, one transmission content on the other transmission resource is indicated, and the sequence index 1 indicates that no transmission is performed 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.

[0117] For example, based on the sequence index corresponding to the first sequence, one transmission content on the other transmission resource is indicated, and the sequence index 1 indicates that no transmission is performed 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.

[0118] 1.1.5 For the indication mode five: the transmission content on the other transmission resource is indicated based on the sequence group index corresponding to the first sequence.

[0119] The sequence group index corresponding to the sequence and the transmission content have a corresponding relationship or an association relationship, and the corresponding relationship or the association relationship is determined based on the protocol pre-defined information or the network configuration information.

[0120] For example, based on the sequence group index corresponding to the first sequence, one transmission content on the other transmission resource is indicated, and the sequence group index 1 indicates that no transmission is performed on the second transmission resource, the sequence group index 2 indicates that the DCI or PDCCH is transmitted on the second transmission resource, and the sequence group index 3 indicates that the first downlink data is transmitted on the second transmission resource, and the present application does not limit this.

[0121] For example, the first sequence corresponds to a sequence group index indicating multiple (two or more) transmission contents on other transmission resources, the sequence group index 9 indicates no transmission on the second transmission resource and no transmission on the third transmission resource, and the sequence group index 10 indicates that the first downlink data is transmitted on the second transmission resource and the feedback information is transmitted on the third transmission resource, and the application does not limit this.

[0122] 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 other transmission resources based on sequence detection, and does not need to perform blind detection in a group of transmission resources, and avoids decoding processing, thereby reducing the power consumption and processing delay of the terminal device.

[0123] The scheme introduces a first-level sequence modulation indication, which can be received by a terminal receiver with small power consumption and complexity, and then determines whether it is necessary to turn on a control / data receiver with larger power consumption. Such operation can better optimize the power consumption of the terminal device.

[0124] The scheme can also adaptively turn on and off the transceiver according to the data throughput and other performance requirements of the terminal device according to the sequence modulation indication information. By defining a universally supported minimum processing core, terminal devices of different capability types can access the network. When the terminal device needs a larger data throughput, it is switched to a larger processing core. Such a terminal device is no longer customized according to a fixed capability specification, and the terminal transceiver can be designed in a modular manner. The terminal device can also modularly turn on and off part of the transceiver according to the data capacity, achieving the effect of dynamic energy saving.

[0125] Step 220: based on the first indication information, performing at least one of downlink transmission and uplink transmission on other transmission resources in the group of transmission resources.

[0126] In some embodiments, the other transmission resources include at least one second transmission resource and / or at least one third transmission resource, wherein the second transmission resource is used for downlink transmission, and the third transmission resource is used for uplink transmission.

[0127] In some embodiments, the method further includes receiving first configuration information, the first configuration information being used to configure one or more groups of transmission resources, and the first configuration information being carried in a system information block (SIB) or radio resource control (RRC) signaling. Optionally, the first configuration information configures at least one group of transmission resources in a semi-static manner.

[0128] By carrying the first configuration information in the SIB or RRC signaling, no additional signaling is needed, signaling transmission overhead is reduced, the terminal device can be quickly configured after connecting the network device, the process of accessing the network is accelerated, and the terminal device can be configured during the system information update process, so that the terminal device is more flexibly managed and adjusted.

[0129] Optionally, the first configuration information is determined based on protocol predefined information, or is determined based on configuration information sent by the network device.

[0130] In some embodiments, by the first configuration information, the network device configures the terminal device with the first transmission resource and the second transmission resource, or configures the terminal device with the first transmission resource and the third transmission resource, or configures the terminal device with the first transmission resource, the second transmission resource and the third transmission resource. In a set of transmission resources, the first transmission resource, the second transmission resource and the third transmission resource can each be multiple. The following embodiments mainly take other transmission resources including one second transmission resource and one third transmission resource as an example.

[0131] 1.2 Correspondence and positional relationship between transmission resources:

[0132] In some embodiments, the correspondence can also be referred to as an association relationship, and the correspondence includes at least one of the following:

[0133] (1) The correspondence between the first transmission resource and the second transmission resource is one-to-one or many-to-one; wherein one-to-one means that one first transmission resource corresponds to one second transmission resource, and many-to-one means that multiple first transmission resources correspond to the same second transmission resource;

[0134] (2) The correspondence between the first transmission resource and the third transmission resource is one-to-one or many-to-one; wherein one-to-one means that one first transmission resource corresponds to one third transmission resource, and many-to-one means that multiple first transmission resources correspond to the same third transmission resource;

[0135] (3) The correspondence between the second transmission resource and the third transmission resource is one-to-one or many-to-one; wherein one-to-one means that one second transmission resource corresponds to one third transmission resource, and many-to-one means that multiple second transmission resources correspond to the same third transmission resource.

[0136] FIG. 3 shows a schematic diagram of the correspondence between the transmission resources provided by an example embodiment of the present application.

[0137] The first indication information is carried in the first transmission resource, the second transmission resource is used for transmitting DCI and / or downlink data, and the third transmission resource is used for transmitting feedback information and / or uplink data. In (a) of FIG. 3, the correspondence between the first transmission resource and the second transmission resource is one-to-one, and the correspondence between the first transmission resource and the third transmission resource is one-to-one; in (b) of FIG. 3, the correspondence between the first transmission resource and the second transmission resource is one-to-one, and the correspondence between the first transmission resource and the third transmission resource is many-to-one, that is, two first transmission resources correspond to the same third transmission resource.

[0138] In the case where the correspondence between the transmission resources is one-to-one, the terminal device can continue to perform instant feedback for each received downlink data, and the feedback delay is low; in the case where the correspondence between the transmission resources is many-to-one, the terminal device feeds back one uplink data for multiple received downlink data, thereby reducing the system overhead of uplink transmission.

[0139] 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 a 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 a network.

[0140] In some embodiments, the position of the third transmission resource is determined based on the position of the first transmission resource; or, there is a predefined relationship between the position of the third transmission resource and the position of the first transmission resource based on a communication protocol; or, there is a preconfigured relationship between the position of the third transmission resource and the position of the first transmission resource based on a network.

[0141] In some embodiments, the position of the third transmission resource is determined based on the position of the second transmission resource; or, there is a predefined relationship between the position of the third transmission resource and the position of the second transmission resource based on a communication protocol; or, there is a preconfigured relationship between the position of the third transmission resource and the position of the second transmission resource based on a network.

[0142] In a case that the position of one transmission resource is determined based on the position of another transmission resource, the time-frequency domain positions of the two transmission resources can be guaranteed to adopt a conventional relationship or a configured relationship, so as to better coordinate and optimize the allocation of the transmission resources, without the need of dynamically scheduling the transmission resources each time, thereby improving the efficiency of data transmission; in a case that the position of one transmission resource and the position of another transmission resource have a relationship predefined based on a communication protocol, the positions of the two can be guaranteed to comply with the communication protocol, thereby ensuring compatibility in different environments; in a case that the position of one transmission resource and the position of another transmission resource have a relationship configured based on a network, the positions of the two transmission resources can be configured based on network configuration information, so that the network device can more reasonably arrange the allocation of the transmission resources according to actual conditions.

[0143] 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:

[0145] The time domain of the first transmission resource is adjacent to the time domain of the second transmission resource, which 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.

[0146] FIG. 4 shows a schematic diagram of the position relationship between transmission resources according to an example embodiment of the present application.

[0147] In part (a) of FIG. 4, the time domain of the first transmission resource is not adjacent to the time domain 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;

[0148] In part (b) of FIG. 4, the time domain of the first transmission resource is adjacent to the time domain 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;

[0149] In part (c) of FIG. 4, 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;

[0150] In the (d) part of FIG. 4, the time-domain starting position of the first transmission resource is the same as the time-domain starting 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.

[0151] In the (e) part of FIG. 4, the time-domain starting position of the first transmission resource is the same as the time-domain starting position of the second transmission resource, and the frequency-domain ending position of the first transmission resource is the same as the frequency-domain ending position of the second transmission resource.

[0152] In some embodiments, the position of the third transmission resource is determined based on the position of the second transmission resource, or there is a predefined relationship between the position of the third transmission resource and the position of the second transmission resource based on a communication protocol, or there is a preconfigured relationship between the position of the third transmission resource and the position of the second transmission resource based on a network.

[0153] By way of example and not limitation, the positional relationship between the third transmission resource and the second transmission resource includes at least one of the following:

[0154] The third transmission resource and the second transmission resource are not adjacent in time domain, the third transmission resource and the second transmission resource are adjacent in time domain, the frequency-domain starting position of the third transmission resource is the same as the frequency-domain starting position of the second transmission resource, the frequency-domain center position of the third transmission resource is the same as the frequency-domain center position of the second transmission resource, and the frequency-domain ending position of the third transmission resource is the same as the frequency-domain ending position of the second transmission resource.

[0155] The third transmission resource and the second transmission resource are adjacent in time domain, which means that the time-domain ending position of the second transmission resource is adjacent to the time-domain starting position of the third transmission resource.

[0156] In the (f) part of FIG. 4, the third transmission resource and the second transmission resource are not adjacent in time domain, and the frequency-domain center position of the third transmission resource is the same as the frequency-domain center position of the second transmission resource.

[0157] In the (g) part of FIG. 4, the third transmission resource and the second transmission resource are not adjacent in time domain, and the frequency-domain starting position of the third transmission resource is the same as the frequency-domain starting position of the second transmission resource.

[0158] In the (h) part of FIG. 4, the third transmission resource and the second transmission resource are not adjacent in time domain, and the frequency-domain ending position of the third transmission resource is the same as the frequency-domain ending position of the second transmission resource.

[0159] In some embodiments, the time domain starting position of the first transmission resource is not later than the time domain starting position of the second transmission resource, and the time domain starting position of the second transmission resource is not later than the time domain starting position of the third transmission resource. For example, when the HARQ feedback of the downlink data on the second transmission resource is carried by the third transmission resource, the time domain starting position of the third transmission resource is slightly later than the time domain starting position of the second transmission resource due to the need to reserve processing time for the terminal device.

[0160] 1.3 The first indication information:

[0161] In some embodiments, the first indication information is used to indicate at least one of the following:

[0162] The second transmission resource carries DCI or a downlink control channel; the second transmission resource carries the first downlink data or a downlink shared channel or a downlink data channel; the third transmission resource carries feedback information; the third transmission resource carries the first uplink data or an uplink shared channel or an uplink data channel; the third transmission resource carries the feedback information and the first uplink data, or the feedback information and the uplink shared channel, or the feedback information and the uplink data channel.

[0163] The downlink control channel is used to carry DCI, the downlink shared channel or the downlink data channel is used to carry the first downlink data, the uplink shared channel or the uplink data channel is used to carry the first uplink data, and the feedback information includes an ACKnowledgement (ACK) or a Negative ACKnowledgement (NACK) corresponding to the first downlink data or the downlink shared channel or the downlink data channel carried on the second transmission resource, and / or an ACK or a NACK corresponding to the second downlink data or the downlink shared channel or the downlink data channel carried on the fourth transmission resource. The fourth transmission resource is a downlink transmission resource scheduled by the DCI carried on the second transmission resource.

[0164] In some embodiments, the feedback information includes at least one of the following information: an ACK or a NACK; a Reference Signal Receiving Quality (RSRQ) obtained based on a measurement reference signal; a Reference Signal Receiving Power (RSRP); Channel State Information (CSI); a Precoding Matrix Indicator (PMI); a Rank Indicator (RI); reference signal index information; and a Link Recovery Request (LRR).

[0165] In some embodiments, the first indication information is further used to indicate whether there is transmission on the other transmission resource; in the case that the first indication information indicates that there is transmission on the other transmission resource, the first indication information is used to indicate the transmission content on the other transmission resource.

[0166] In some embodiments, the first indication information is used to indicate whether there is transmission on the second transmission resource and / or the third transmission resource; in the case that the first indication information indicates that there is transmission on the second transmission resource, the first indication information is used to indicate the transmission content on the second transmission resource; in the case that the first indication information indicates that there is transmission on the third transmission resource, the first indication information is used to indicate the transmission content on the third transmission resource.

[0167] In some embodiments, the first indication information is used to indicate the transmission content on the other transmission resource. If the first indication information indicates the transmission content on the second transmission resource, it can be determined that there is transmission on the second transmission resource; if the first indication information indicates the transmission content on the third transmission resource, it can be determined that there is transmission on the third transmission resource.

[0168] By indicating whether there is transmission on the other transmission resource through the first indication information, in the case that it is indicated that there is no transmission on the second transmission resource, the terminal device does not need to detect on the second transmission resource; in the case that it is indicated that there is no transmission on the third transmission resource, the terminal device does not need to transmit on the third transmission resource, thereby reducing the energy consumption of the terminal device.

[0169] FIG. 5 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 manners:

[0170] 1.3.1. Manner 1: indicating no transmission on the second transmission resource.

[0171] In the case that the first indication information indicates no transmission on the second transmission resource, the terminal device does not need to detect on the second transmission resource.

[0172] Optionally, a first value or 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 resource based on the first value or the first state or the first sequence.

[0173] The first value is a bit value or a group of bit values, such as a value of 1 or 0 of the first value; the first state is an on state or an off state, which can be represented by a high or low level or a high or low energy, or can be represented by a bit value; the first sequence is a sequence used to represent the first indication information, for example, a ZC sequence. The principles of representation of the second value, the second state, the second sequence, the third value, the third state, the third sequence and other values, states and sequences are the same, and will not be described again.

[0174] 1.3.2 Way 2: Indicate the second transmission resource to transmit DCI or PDCCH.

[0175] In some embodiments, based on the first indication information, the DCI or PDCCH is received on the second transmission resource.

[0176] In the case where the first indication information indicates that the second transmission resource transmits the DCI or PDCCH, 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.

[0177] By indicating that the DCI or PDCCH is transmitted on the second transmission resource in the case where the first indication information indicates that the DCI or PDCCH is transmitted on the second transmission resource, it is not necessary to continuously detect the PDCCH on all second transmission resources, which reduces the detection complexity and achieves the effect of energy saving and consumption reduction.

[0178] Optionally, the DCI is carried on the PDCCH or the PDSCH. FIG. 6 shows a schematic diagram of a DCI transmission manner provided by an exemplary embodiment of the present application.

[0179] In some embodiments, the DCI is carried by a medium access control control element (MAC CE), and the MAC CE is carried by the PDSCH.

[0180] For example, in (a) of FIG. 6, the MAC CE is carried by the PDSCH, and the MAC CE carries the DCI; in (b) of FIG. 6, the DCI is carried by the PDCCH.

[0181] Optionally, the second value or the second state or the second sequence is determined based on the first indication information, and the DCI or PDCCH is determined to be transmitted on the second transmission resource based on the second value or the second state or the second sequence.

[0182] In some embodiments, based on the first indication information, the DCI or the downlink control channel is received on the second transmission resource, and the second downlink data is received on the fourth transmission resource, which is indicated by the DCI or the downlink control channel on the second transmission resource.

[0183] In some embodiments, the method further comprises: transmitting, based on the first indication information, feedback information corresponding to the second downlink data on the third transmission resource.

[0184] As shown in FIG. 7, the second transmission resource, the third transmission resource, and the fourth transmission resource are different transmission resources, only DCI or a downlink control channel is received on the second transmission resource, the second downlink data is received on the fourth transmission resource, the feedback information corresponding to the second downlink data is transmitted on the third transmission resource, and the fourth transmission resource is indicated by the DCI or the downlink control channel.

[0185] 1.3.3. Mode 3: Indicating that the first downlink data is transmitted on the second transmission resource.

[0186] In some embodiments, the first downlink data is received on the second transmission resource based on the first indication information. Optionally, in the case where the second transmission resource is not indicated to transmit the first downlink data, it is not necessary to detect the first downlink data on the second transmission resource.

[0187] In the case where the first indication information indicates that the second transmission resource transmits the first downlink data, the terminal device detects the first downlink data on the second transmission resource.

[0188] Optionally, the first downlink data is carried by a PDSCH.

[0189] Optionally, a third value or a third state or a third sequence is determined based on the first indication information, and the first downlink data is determined to be transmitted on the second transmission resource based on the third value or the third state or the third sequence.

[0190] Since the first indication information does not carry resource scheduling information, the transmission parameters corresponding to the first downlink data are determined based on protocol pre-defined information or network configuration information. In some embodiments, the transmission parameters include at least one of the following:

[0191] a modulation mode or a 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; a layer number corresponding to the first downlink data; Antenna port information corresponding to the first downlink data; DeModulation Reference Signal (DMRS) information corresponding to the first downlink data;

[0192] Among them, the TBS can be configured by the network, and 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 and the like.

[0193] Optionally, the DMRS information corresponding to the first downlink data is determined by 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.

[0194] In some embodiments, the first downlink data corresponds to small data packet transmission. The small data packet transmission can be understood as a transmission block size less than or equal to a threshold value, and the threshold value is determined based on protocol predefined information or network configuration information.

[0195] 1.3.4 Mode 4: indicating that the first downlink data is transmitted on the second transmission resource, and the feedback information is transmitted on the third transmission resource.

[0196] In some embodiments, based on the first indication information, the first downlink data is received on the second transmission resource, and the feedback information corresponding to the first downlink data is transmitted on the third transmission resource.

[0197] In the case where the first indication information indicates that the first downlink data is transmitted on the second transmission resource, and the feedback information is transmitted on the third transmission resource, the terminal device detects the first downlink data on the second transmission resource. Optionally, the first downlink data is carried by PDSCH.

[0198] The terminal device transmits the feedback information, such as Hybrid Automatic Repeat reQuest (HARQ) information, on the third transmission resource, and the HARQ information is used to indicate whether the first downlink data is correctly received, and the HARQ information includes ACK or NACK.

[0199] Optionally, a fourth value or a fourth state or a fourth sequence is determined based on the first indication information, and the first downlink data is transmitted on the second transmission resource based on the fourth value or the fourth state or the fourth sequence, and the feedback information is transmitted on the third transmission resource.

[0200] In some embodiments, 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 and feeds back.

[0201] Since there is a corresponding relationship between the first transmission resource and the third transmission resource, or between the second transmission resource and the third transmission resource, the terminal device can determine the third transmission resource based on the first transmission resource or the second transmission resource, and transmit the feedback information, such as HARQ feedback information ACK or NACK, corresponding to the first downlink data on the third transmission resource.

[0202] In some embodiments, the feedback information comprises at least one of: HARQ information; PMI information; RI information; CSI; reference signal index information; and LRR, and which feedback information is specifically fed back can be determined based on network configuration information or the first indication information.

[0203] Optionally, the feedback information is carried by a PUCCH, and a PUCCH format and / or a PUCCH resource are determined based on network configuration information or the first indication information.

[0204] In some embodiments, in a case where the plurality of second transmission resources correspond to one third transmission resource, the third transmission resource is used to transmit feedback information corresponding to the first downlink data transmitted on the plurality of second transmission resources.

[0205] The second transmission resources and the third transmission resource are in a many-to-one correspondence, that is, n (n is greater than 1) second transmission resources correspond to one third transmission resource, and the third transmission resource is used to transmit feedback information corresponding to the first downlink data transmitted on the n second transmission resources.

[0206] In some embodiments, the feedback manner comprises at least one of:

[0207] Feedback manner 1: n feedback information bundling feedback: performing a bit-wise operation or a bit-or operation on feedback information corresponding to the first downlink data transmitted on the n second transmission resources to obtain 1-bit information, and feeding back the 1-bit information.

[0208] Feedback manner 2: The feedback information comprises n information fields (n bits), which respectively correspond to the first downlink data on the n second transmission resources.

[0209] If the terminal device detects the first downlink data (detection success or detection failure) on the i-th second transmission resource, the terminal device feeds back ACK or NACK on the i-th bit; if the terminal device does not detect the first downlink data on the i-th second transmission resource, the terminal device does not feed back (for example, fills in a specified character NULL) or feeds back NACK or ACK on the i-th bit.

[0210] FIG. 8 shows a schematic diagram of a feedback manner provided by an example embodiment of the present application. The second transmission resources and the third transmission resource are in a many-to-one correspondence, and in FIG. 8, 4 second transmission resources correspond to 1 third transmission resource, and feedback information corresponding to downlink data on the 4 second transmission resources is all fed back through the same third transmission resource.

[0211] Assume that the first second transmission resource transmits the first downlink data 1, the terminal device detects successfully, and the feedback information is ACK; the fourth second transmission resource transmits the first downlink data 2, the terminal device detects unsuccessfully, and the feedback information is NACK; and no transmission is performed on the second second transmission resource and the third second transmission resource.

[0212] If the feedback mode 1 is adopted, multiple feedback information is fed back by binding (for example, bit-wise operation) feedback. Since the feedback information corresponding to the fourth second transmission resource is NACK, the feedback information corresponds to 1 bit NACK.

[0213] If the feedback mode 2 is adopted, the feedback information of the third transmission resource corresponds to 4 bits, which correspond to the downlink transmission on the four second transmission resources respectively. The first downlink data 1 and the first downlink data 2 correspond to the first bit and the fourth bit in the 4 bits respectively. The second bit and the third bit in the 4 bits correspond to the second second transmission resource and the third second transmission resource. Since no transmission is performed on the two second transmission resources, the feedback information bits corresponding to the two second transmission resources are empty (or NULL) respectively.

[0214] Optionally, if the first indication information indicates that the first downlink data is transmitted on the second transmission resource, and the terminal device does not successfully detect the first downlink data, the terminal device sends NACK on the third transmission resource; if the terminal device successfully detects the first downlink data, the terminal device does not feedback (that is, does not send ACK) on the third transmission resource.

[0215] Optionally, if the first indication information indicates that the first downlink data is transmitted on the second transmission resource, and the terminal device successfully detects the first downlink data, the terminal device sends ACK on the third transmission resource; if the terminal device does not successfully detect the first downlink data, the terminal device does not feedback (that is, does not send NACK) on the third transmission resource.

[0216] In some embodiments, if the first downlink data includes one transport block or codeword, the feedback information corresponds to 1 bit; if the first downlink data includes m transport blocks or codewords (m is greater than or equal to 2), the feedback information corresponds to m bits, or the feedback information corresponds to 1 bit, that is, the bit-wise operation or the bit-wise OR operation of all the feedback information corresponding to the m transport blocks or codewords is performed to obtain 1 bit of feedback information.

[0217] By way of example and not limitation, the feedback information corresponds to 1 bit, and the value of the 1 bit is determined based on the bit-wise operation or the bit-wise OR operation of the feedback information corresponding to the first downlink data transmitted on the multiple second transmission resources. The 1 bit is used to indicate the positive acknowledgement or the negative acknowledgement.

[0218] As an example but not limitation, the feedback information corresponds to n bits, the i-th bit corresponds to the feedback information of the first downlink data transmitted on the i-th second transmission resource, and the feedback information includes positive acknowledgement or negative acknowledgement; wherein the multiple second transmission resources include n second transmission resources, i and n are positive integers, and i is less than or equal to n.

[0219] Optionally, in the case that the first downlink data is not detected on the i-th second transmission resource, the i-th bit is used to indicate negative feedback or positive feedback or no feedback.

[0220] FIG. 9 shows a schematic diagram of a feedback mode according to an example embodiment of the present application.

[0221] In (a) of FIG. 9, 4 second transmission resources correspond to 1 third transmission resource, the feedback information transmitted on the third transmission resource corresponds to 1 bit, and the same code word 1 is transmitted on the 4 second transmission resources. As long as one code word 1 is successfully detected, the feedback information is ACK. Assuming that the code word 1 on the first second transmission resource is successfully detected, the feedback information on the third transmission resource is determined to be ACK based on the OR operation of the bits.

[0222] In (b) of FIG. 9, 4 second transmission resources correspond to 1 third transmission resource, the feedback information transmitted on the third transmission resource corresponds to 1 bit, and code word 0, code word 1, code word 2 and code word 3 are respectively transmitted on the 4 second transmission resources. The value of the feedback information on the third transmission resource is determined based on the AND operation of the feedback information corresponding to the 4 code words. Only when all the 4 code words are successfully detected, the feedback information is ACK, otherwise the feedback information is NACK.

[0223] FIG. 10 shows a schematic diagram of a feedback mode according to an example embodiment of the present application.

[0224] In (a) of FIG. 10, if the feedback information transmitted on the third transmission resource corresponds to 1 bit, 4 second transmission resources transmit the same codeword 1 and codeword 0, and the value of the 1 bit of the feedback information on the third transmission resource is determined based on the bit-wise comparison of the feedback information corresponding to the codeword 1 and the feedback information corresponding to the codeword 0, if the codeword 1 is successfully detected on any one of the second transmission resources, and the codeword 0 is successfully detected on any one of the second transmission resources, the feedback information is ACK, otherwise the feedback information is NACK. Assuming that the codeword 1 is successfully detected on the first second transmission resource, and the codeword 0 is successfully detected on the second second transmission resource, the feedback information on the third transmission resource is ACK. If the feedback information transmitted on the third transmission resource corresponds to 2 bits, 4 second transmission resources transmit the same codeword 1 and codeword 0, and the value of the 2 bits of the feedback information on the third transmission resource is determined based on the feedback information corresponding to the codeword 1 and the feedback information corresponding to the codeword 0 respectively, if the codeword 1 is successfully detected on any one of the second transmission resources, the first bit of the 2 bits of the feedback information is ACK, otherwise the first bit of the 2 bits of the feedback information is NACK; if the codeword 0 is successfully detected on any one of the second transmission resources, the first bit of the 2 bits of the feedback information is ACK, otherwise the feedback information is NACK. Assuming that the codeword 1 is successfully detected on the first second transmission resource, it is determined that the first bit of the feedback information is ACK; and the codeword 0 is not successfully detected on any one of the four second transmission resources, it is determined that the second bit of the feedback information is NACK.

[0225] In (b) of FIG. 10, 4 second transmission resources correspond to 1 third transmission resource. If the feedback information transmitted on the third transmission resource corresponds to 1 bit, the value of the bit is determined based on the bit-wise AND operation of the feedback information corresponding to all the code words transmitted on the 4 second transmission resources. If the code words 1 and 2, the code words 3 and 4, the code words 5 and 6, and the code words 7 and 8 are respectively transmitted on the 4 second transmission resources, the feedback information is ACK only if the code words 1, 2, 3, 4, 5, 6, 7 and 8 are all successfully detected, otherwise, the feedback information is NACK. Assuming that the code words 1, 3, 5 and 7 are successfully detected, but the code words 2, 4, 6 and 8 are not detected, the feedback information on the third transmission resource is determined to be NACK based on the bit-wise AND operation. If the feedback information transmitted on the third transmission resource corresponds to 2 bits, the value of the first bit is determined based on the bit-wise AND operation of the feedback information corresponding to the first code words transmitted on the 4 second transmission resources, and the value of the second bit is determined based on the bit-wise AND operation of the feedback information corresponding to the second code words transmitted on the 4 second transmission resources. If the code words 1 and 2, the code words 3 and 4, the code words 5 and 6, and the code words 7 and 8 are respectively transmitted on the 4 second transmission resources, the first bit of the feedback information is ACK only if the code words 1, 3, 5 and 7 are successfully detected on the first bit, otherwise, the first bit of the feedback information is NACK; the second bit of the feedback information is ACK only if the code words 2, 4, 6 and 8 are successfully detected on the second bit, otherwise, the second bit of the feedback information is NACK. Assuming that the code words 1, 3, 5 and 7 are successfully detected on the first bit, the first bit of the feedback information is determined to be ACK based on the bit-wise AND operation; the code words 2, 4 and 6 are successfully detected on the second bit, but the code word 8 is not successfully detected, the second bit of the feedback information is determined to be NACK based on the bit-wise AND operation.

[0226] In the case where the feedback information corresponds to 1 bit, the transmission resources occupied by the feedback information can be reduced, and the overhead can be reduced. In the case where the feedback information corresponds to n bits, whether the first downlink data is detected can be more accurately and specifically fed back for the n second transmission resources.

[0227] 1.3.5 Mode 5: Indicating that the second transmission resources transmit the first downlink data, and the third transmission resources transmit the feedback information and / or the first uplink data.

[0228] In the case where the first indication information indicates that the second transmission resources transmit the first downlink data, and the third transmission resources transmit the feedback information and / or the first uplink data, the terminal device detects the first downlink data on the second transmission resources; and the terminal device transmits the feedback information and / or the first uplink data on the third transmission resources, and the feedback information is used to indicate whether the first downlink data is correctly received.

[0229] Optionally, the fifth value or the fifth state or the fifth sequence is determined based on the first indication information, and the first uplink data is transmitted on the third transmission resource based on the fifth value or the fifth state or the fifth sequence.

[0230] In some embodiments, the feedback information and the first uplink data are resource multiplexed, the feedback information is carried by a MAC CE, and the MAC CE and the first uplink data are carried by a PUSCH; the first uplink data is carried by a PUSCH, and the feedback information and the PUSCH are resource multiplexed, that is, the feedback information and the PUSCH correspond to different resources in the third transmission resource.

[0231] Optionally, the first uplink data corresponds to small data packet transmission. The small data packet transmission can be understood as a transmission block size less than or equal to a threshold value, and the threshold value is determined based on protocol predefined information or network configuration information. Since the first indication information does not carry resource scheduling information, the transmission parameters corresponding to the first uplink data are determined based on protocol definition information or network configuration information.

[0232] 1.3.6 Mode 6: Indicating that the first uplink data is transmitted on the third transmission resource.

[0233] In some embodiments, the first uplink data is transmitted on the third transmission resource based on the first indication information.

[0234] In the case where the first indication information indicates that the first uplink data is transmitted on the third transmission resource, the terminal device transmits the first uplink data on the third transmission resource.

[0235] Optionally, the first uplink data is carried by a PUSCH.

[0236] Optionally, the sixth value or the sixth state or the sixth sequence is determined based on the first indication information, and the first uplink data is transmitted on the third transmission resource based on the sixth value or the sixth state or the sixth sequence.

[0237] In some embodiments, the network device configures the third transmission resource for the terminal device for uplink transmission, and the network device transmits the first indication information to the terminal device through the first transmission resource, to indicate whether the terminal device can perform uplink transmission on the third transmission resource.

[0238] For example, the network device configures a third transmission resource for the terminal device, the third transmission resource is an uplink configured grant (UL CG) resource, including a type 1 UL CG resource or a type 2 UL CG resource, or other types of UL CG resources, and when the network device sends the first indication information indicating the sixth value to the terminal device, the terminal device can send the first uplink data by using the third transmission resource.

[0239] Since the first indication information does not carry resource scheduling information, the transmission parameters corresponding to the first uplink data are determined based on protocol predefined information or network configuration information. In some embodiments, the transmission parameters include at least one of the following:

[0240] a modulation mode or an MCS level corresponding to the first uplink data; a coding mode corresponding to the first uplink data; a coding rate corresponding to the first uplink data; a layer number corresponding to the first uplink data; antenna port information corresponding to the first uplink data; DMRS information corresponding to the first uplink data;

[0241] The TBS can be configured by the network. 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 other processing.

[0242] Optionally, the DMRS information corresponding to the first uplink data is determined by 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; DMRS sequence initialization information.

[0243] In some embodiments, the first uplink data corresponds to small data packet transmission. Small data packet transmission can be understood as a transmission block size smaller than or equal to a threshold value, and the threshold value is determined based on protocol predefined information or network configuration information.

[0244] 1.3.7 Mode 7: Indicating the second transmission resource to transmit DCI and the first downlink data.

[0245] In some embodiments, based on the first indication information, the DCI and the first downlink data are received simultaneously on the second transmission resource; or, based on the first indication information, the downlink control channel and the first downlink data are received simultaneously on the second transmission resource.

[0246] By way of example but not limitation, the DCI is used to schedule the second downlink data; or, the DCI is used to schedule the second uplink data.

[0247] The DCI is used for scheduling the second downlink data, including: the DCI is used for indicating a transmission resource (i.e., a fourth transmission resource) of the second downlink data, and / or the DCI is used for indicating a transmission resource of feedback information corresponding to the second downlink data, and / or the DCI is used for indicating a transmission parameter of the second downlink data; and the DCI is used for scheduling the second uplink data, including: the DCI is used for indicating a transmission resource of the second uplink data, and / or the DCI is used for indicating a transmission parameter of the second uplink data.

[0248] In some embodiments, the method further includes: receiving the second downlink data on the fourth transmission resource, the fourth transmission resource being indicated by the DCI or a downlink control channel.

[0249] Based on the first indication information, transmitting feedback information corresponding to the first downlink data, or feedback information corresponding to the second downlink data, or feedback information corresponding to the first downlink data and the second downlink data on the third transmission resource.

[0250] For example, 1 bit is used to correspond to feedback information of the first downlink data and the second downlink data, for example, 1 bit is obtained through a bit and operation or bit or operation, and the 1 bit is used for feedback; or 2 bits are used to correspond to feedback information of the first downlink data and the second downlink data respectively.

[0251] By simultaneously receiving the DCI and the first downlink data on the second transmission resource, the resource utilization efficiency and the data transmission efficiency of the second transmission resource are improved; by receiving the second downlink data on the fourth transmission resource, the second downlink data and the DCI are transmitted on different transmission resources, so as to reduce possible channel interference and improve the reliability of data transmission.

[0252] As shown in FIG. 11, the second transmission resource, the third transmission resource, and the fourth transmission resource are different transmission resources, the DCI and the first downlink data are received on the second transmission resource, the second downlink data is received on the fourth transmission resource, and feedback information corresponding to the first downlink data, or feedback information corresponding to the second downlink data, or feedback information corresponding to the first downlink data and the second downlink data is transmitted on the third transmission resource, the fourth transmission resource being indicated by the DCI.

[0253] In some embodiments, the DCI is carried by a MAC CE, and the MAC CE and the first downlink data are carried by a PDSCH.

[0254] In some embodiments, the first downlink data is carried by a PDSCH, and a transmission resource used for transmitting the DCI and the PDSCH corresponds to different transmission resources on the second transmission resource.

[0255] In some embodiments, based on the first indication information, the DCI or the downlink control channel is received on the second transmission resource, the second uplink data is transmitted on the fifth transmission resource, and the fifth transmission resource is indicated by the DCI or the downlink control channel on the second transmission resource; and based on the first indication information, the first downlink data is received on the second transmission resource, and the feedback information corresponding to the first downlink data is transmitted on the third transmission resource.

[0256] By receiving the DCI or the downlink control channel and the first downlink data on the second transmission resource, transmitting the second uplink data on the fifth transmission resource, and transmitting the feedback information corresponding to the second uplink data and the first downlink data on different transmission resources, the channel interference that may exist is reduced, and the reliability of data transmission is improved.

[0257] In some embodiments, based on the first indication information, the DCI or the downlink control channel is received on the second transmission resource, the second uplink data is transmitted on the fifth transmission resource, and the fifth transmission resource is indicated by the DCI or the downlink control channel on the second transmission resource; and based on the first indication information, the first downlink data is received on the second transmission resource, and the feedback information corresponding to the first downlink data is transmitted on the third transmission resource.

[0258] FIG. 12 shows a schematic diagram of an indication manner of the first indication information according to an example embodiment of the present application. The second transmission resource and the fifth transmission resource are different transmission resources, the DCI and the first downlink data are received on the second transmission resource, the second uplink data is transmitted on the fifth transmission resource, the fifth transmission resource is indicated by the DCI, the feedback information corresponding to the first downlink data is transmitted on the third transmission resource, and the fifth transmission resource is different from the third transmission resource in the above embodiments.

[0259] 1.4 The first indication information is used to indicate a first value:

[0260] In some embodiments, the first indication information is used to indicate a first value, and the first value is associated with the transmission content.

[0261] Optionally, the correspondence between the first value and the transmission content is determined by protocol predefinition information or network configuration information.

[0262] For example, the first indication information is used to indicate three values of the first value, and the correspondence between the first value and the transmission content is shown in Table 2:

[0263] Table 2

[0264] For example, when the first value is 0, the corresponding transmission content is "no transmission on the second transmission resource"; when the first value is 1, the corresponding transmission content is "transmission of PDCCH or DCI on the second transmission resource"; and when the first value is 2, the corresponding transmission content is "transmission of the first downlink data on the second transmission resource". The first value is expressed in decimal form, and in actual implementation, binary form can be used, which is not limited in the embodiment.

[0265] For example, the first indication information is used to indicate 6 values of the first value, and the correspondence between the first value and the transmission content is shown in Table 3. "No transmission" means that there is no transmission on the transmission resource, and "not involved" means that the information is not used to indicate the transmission on the transmission resource.

[0266] Table 3

[0267] For example, the first value is 0, the corresponding transmission content is "no transmission (or not involved) on the second transmission resource, and no transmission (or not involved) on the third transmission resource"; the first value is 1, the corresponding transmission content is "transmission of PDCCH or DCI on the second transmission resource, and no transmission (or not involved) on the third transmission resource"; the first value is 2, the corresponding transmission content is "transmission of the first downlink data on the second transmission resource, and no transmission (or not involved) on the third transmission resource"; the first value is 3, the corresponding transmission content is "transmission of the first downlink data on the second transmission resource, and transmission of feedback information on the third transmission resource"; the first value is 4, the corresponding transmission content is "transmission of the first downlink data on the second transmission resource, and transmission of the first uplink data and feedback information on the third transmission resource"; and the first value is 5, the corresponding transmission content is "no transmission (or not involved) on the second transmission resource, and transmission of the first uplink data on the third transmission resource".

[0268] For example, when the first value is 0, the corresponding transmission content is "no transmission on the second transmission resource"; when the first value is 1, the corresponding transmission content is "transmission of PDCCH or DCI on the second transmission resource"; and when the first value is 2, the corresponding transmission content is "transmission of the first downlink data on the second transmission resource". The first value is expressed in decimal form, and in actual implementation, binary form can be used, which is not limited in the embodiment.

[0269] 1.5 The first indication information is carried by a sequence:

[0270] In some embodiments, the first indication information is carried by a sequence, and the sequence index of the sequence is associated with the transmission content.

[0271] Optionally, the correspondence between the sequence index and the transmission content is determined by protocol predefined information or network configuration information.

[0272] For example, the first indication information is carried by three sequences, and the correspondence between the sequence index and the transmitted content is shown in Table 4:

[0273] Table 4

[0274] 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 PDCCH or DCI on the second transmission resource"; when the sequence index is 2, the corresponding transmission content is "transmission of first downlink data on the second transmission resource".

[0275] For example, the first indication information is carried by six sequences, and the correspondence between the sequence index and the transmitted content is shown in Table 5:

[0276] Table 5

[0277] The absence of transmission on the second transmission resource (or non-involvement) includes the case where the second transmission resource is not configured, and the case where the second transmission resource is configured but no transmission occurs on the second transmission resource; the absence of transmission on the third transmission resource (or non-involvement) includes the case where the third transmission resource is not configured, and the case where the third transmission resource is configured but no transmission occurs on the third transmission resource.

[0278] For example, when the sequence index is 0, the corresponding transmission content is "no transmission (or not involved) on the second transmission resource, no transmission (or not involved) on the third transmission resource"; when the sequence index is 1, the corresponding transmission content is "transmission of PDCCH or DCI on the second transmission resource, no transmission (or not involved) on the third transmission resource"; when the sequence index is 2, the corresponding transmission content is "transmission of the first downlink data on the second transmission resource, no transmission (or not involved) on the third transmission resource"; when the sequence index is 3, the corresponding transmission content is "transmission of the first downlink data on the second transmission resource, transmission of feedback information on the third transmission resource"; when the sequence index is 4, the corresponding transmission content is "transmission of the first downlink data on the second transmission resource, transmission of the first uplink data and feedback information on the third transmission resource"; when the sequence index is 5, the corresponding transmission content is "no transmission (or not involved) on the second transmission resource, transmission of the first uplink data on the third transmission resource".

[0279] 1.6 A set of transmission resource types:

[0280] In some embodiments, a set of transmission resources is a common transmission resource shared by multiple terminal devices; or, a set of transmission resources is a group transmission resource shared by a group of terminal devices; or, a set of transmission resources is a proprietary transmission resource used by a terminal device.

[0281] In some embodiments, when the set of transmission resources is common transmission resources shared by multiple terminal devices or group transmission resources shared by a group of terminal devices, the other transmission resources in the set of transmission resources include a second transmission resource, the second transmission resource is used for transmission of common DCI and / or common downlink data, the common DCI and / or common downlink data are used for transmission of at least one of the following information: broadcast information, system information, paging information, random access response information.

[0282] In some embodiments, when the set of transmission resources is common transmission resources shared by multiple terminal devices or group transmission resources shared by a group of terminal devices, the other transmission resources in the set of transmission resources include a third transmission resource, the third transmission resource is used for transmission of a random access sequence by a terminal device.

[0283] The network device configures the same first transmission resource and the same second transmission resource for the plurality of terminal devices, i.e., the first transmission resource and the second transmission resource are common transmission resources shared by the plurality of terminal devices; the network device configures the same sequence for the plurality of terminal devices, or the network device configures respective corresponding sequences for the plurality of terminal devices respectively, and the terminal device detects the first indication information on the first transmission resource based on the configured sequence.

[0284] For example, the network device configures sequence 1 for terminal device 1 and configures sequence 1 for terminal device 2, and terminal device 1 and terminal device 2 both detect the first indication information on the first transmission resource based on sequence 1.

[0285] For example, the network device configures sequence 1 for terminal device 1 and configures sequence 2 for terminal device 2, 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.

[0286] The network device configures a set of transmission resources for transmission of common DCI and / or 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.

[0287] In some embodiments, the plurality of terminal devices detect whether there is first indication information on the first transmission resource based on the same common sequence.

[0288] For example, the network device configures a common sequence 1 for terminal device 1 and terminal device 2, and terminal device 1 and terminal device 2 detect the first indication information on the first transmission resource based on the common sequence 1.

[0289] 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, 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, random access response information.

[0290] For example, the broadcast information is Master Information Block (MIB) information; the system information is SIB information; the paging information is Paging information; and the random access response information is Random Access Response (RAR) information.

[0291] In some embodiments, the network device configures a common transmission resource, including a common first transmission resource and a common second transmission resource, for transmitting the common DCI and the common downlink data.

[0292] 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.

[0293] In some embodiments, the network device configures a group transmission resource common to a terminal device group, including a group first transmission resource and a group second transmission resource, the group second transmission resource is used to transmit group common DCI and group common downlink data.

[0294] Optionally, the terminal device group includes all terminal devices in the cell, and the group first transmission resource and the group second transmission resource can also be referred to as a shared first transmission resource and a shared second transmission resource.

[0295] For example, the common DCI and the common downlink data are used to transmit at least one of the following information: 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 information, and Wake-up indication.

[0296] In some embodiments, the network device configures, for each terminal device, a user-specific (UE-specific) dedicated first transmission resource and a dedicated second transmission resource, respectively, for transmitting a user-specific DCI and user-specific downlink data corresponding to each terminal device.

[0297] In some embodiments, the dedicated first transmission resources of different terminal devices are non-overlapping, fully overlapping or partially overlapping, and the dedicated second transmission resources of different terminal devices are non-overlapping, fully overlapping or partially overlapping.

[0298] For example, FIG. 13 shows a schematic diagram of configuring transmission resources according to an example embodiment of the present application, in which the network device configures common transmission resources 1310, group transmission resources 1320 and dedicated transmission resources 1330.

[0299] In this example, the common transmission resources 1310 include two groups of common first transmission resources and common second transmission resources, the group transmission resources 1320 include two groups of group first transmission resources and group second transmission resources, and the dedicated transmission resources 1330 include eight groups of dedicated first transmission resources and dedicated second transmission resources. For the dedicated transmission resources 1330, the network device can configure one or more dedicated first transmission resources and dedicated second transmission resources for each terminal device.

[0300] Suppose 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 (e.g., detecting whether there is first indication information in the first transmission resources) in these four groups of transmission resources, and then detect the DCI and / or downlink data in the corresponding second transmission resources.

[0301] By dividing a group of transmission resources into different types of transmission resources, the range of detection by the terminal device is reduced and the detection efficiency is improved when the network device configures at least one of common transmission resources, group transmission resources and dedicated transmission resources.

[0302] 1.7 Determine information based on protocol pre-defined information or network configuration information:

[0303] (1) The second transmission resources are used to transmit DCI or downlink control channels.

[0304] In some embodiments, the DCI is carried by PDCCH, the network device configures a search space in the second transmission resources by sending network configuration information, and the terminal device detects PDCCH in the search space.

[0305] In some embodiments, in the case that the first indication information is used to indicate that the DCI or the downlink control channel 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:

[0308] (2) The second transmission resource is used to transmit the first downlink data.

[0309] In some embodiments, the second transmission resource is used to transmit the downlink data, and the downlink data is carried by a PDSCH.

[0310] 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.

[0311] In some embodiments, in the case that 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:

[0313] The TBS can be configured by the network device, and if the data packet to be transmitted is smaller than the TBS, the data packet size can be made equal to the TBS by filling redundant bits or the like.

[0314] 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.

[0315] 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 packet transmission (SDT).

[0316] (3) The third transmission resource is used for transmission of the first uplink data.

[0317] In some embodiments, in the case where the first indication information is used to indicate that the first uplink data is transmitted on the third transmission resource, at least one of the following information is determined based on protocol predefined information or network configuration information:

[0318] a TBS corresponding to the first uplink data; a MCS table corresponding to the first uplink data; a modulation mode or MCS level corresponding to the first uplink data; a coding mode corresponding to the first uplink data; a coding rate corresponding to the first uplink data; a number of layers corresponding to the first uplink data; antenna port information corresponding to the first uplink data; and DMRS information corresponding to the first uplink data.

Optionally, the DMRS information corresponding to the first uplink data is determined based on protocol predefined information, network configuration information, or the first indication information.

[0320] 1.8 A set of transmission resources includes a first transmission resource and a second transmission resource:

[0321] In some embodiments, the terminal device receives the first transmission resource and the second transmission resource configured by the network device, and the first transmission resource and the second transmission resource have a corresponding relationship. Optionally, the corresponding relationship between the first transmission resource and the second transmission resource is one-to-one.

[0322] The positional relationship between the first transmission resource and the second transmission resource is described in the embodiment of FIG. 4, which is not repeated here.

[0323] In some embodiments, the first indication information is used to indicate at least one of the following ways:

[0324] 1.8.1 Way 1: Indicating no transmission on the second transmission resource.

[0325] In the case where the first indication information indicates no transmission on the second transmission resource, the terminal device does not need to detect on the second transmission resource. For specific implementation details, please refer to Way 1 of 1.3.1 above, which will not be repeated here.

[0326] 1.8.2 Way 2: Indicating transmission of DCI or PDCCH on the second transmission resource.

[0332] 1.8.5 The first indication information is used to indicate a first value:

[0333] In some embodiments, the first indication information is used to indicate a first value, and the first value is associated with the transmission content.

[0334] 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 as shown in Table 6:

[0335] Table 6

[0336] For example, when the first value is 0, the corresponding transmission content is "no transmission on the second transmission resource"; when the first value is 1, the corresponding transmission content is "transmission of PDCCH or DCI on the second transmission resource"; when the first value is 2, the corresponding transmission content is "transmission of first downlink data on the second transmission resource"; and when the first value is 3, the corresponding transmission content is "transmission of DCI and first downlink data on the second transmission resource".

[0337] 1.8.6 The first indication information is carried by a sequence.

[0338] In some embodiments, the first indication information is carried by a sequence, and a sequence index of the sequence is associated with the transmission content.

[0339] 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 7.

[0340] Table 7

[0341] 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 PDCCH or DCI on the second transmission resource"; when the sequence index is 2, the corresponding transmission content is "transmission of first downlink data on the second transmission resource"; and when the sequence index is 3, the corresponding transmission content is "transmission of DCI and first downlink data on the second transmission resource".

[0342] In some embodiments, the DCI and the first downlink data are resource multiplexed, that is, the DCI and the first downlink data are both transmitted on the second transmission resource, but correspond to different transmission resources in the second transmission resource.

[0343] For example, the DCI is mapped first (first frequency domain mapping and then time domain mapping, or first time domain mapping and then frequency domain mapping) in the second transmission resource, and the first downlink data is mapped on the remaining transmission resource.

[0344] Alternatively, the DCI is mapped based on the DMRS symbol position corresponding to the PDSCH carrying the first downlink data, for example, the DCI is mapped from the first DMRS symbol (first frequency domain mapping and then time domain mapping), or the DCI is mapped from the next symbol of the first DMRS symbol (first frequency domain mapping and then time domain mapping), which is not limited in the embodiments of the present application.

[0345] In some embodiments, the DCI and the first downlink data are transmitted on the second transmission resource, the DCI is used to schedule a downlink transmission resource, and the downlink transmission resource is used to transmit second downlink data.

[0346] In some embodiments, the second transmission resource transmits the DCI and the first downlink data, and the DCI is used to schedule an uplink transmission resource, and the uplink transmission resource is used to transmit second uplink data.

[0347] In some embodiments, the second transmission resource transmits the DCI and the first downlink data, and the DCI is used to schedule an uplink transmission resource, and the uplink transmission resource is used to transmit feedback information corresponding to the first downlink data.

[0348] In some embodiments, the second transmission resource transmits the DCI and the first downlink data, and the DCI is used to schedule an uplink transmission resource, and the uplink transmission resource is used to transmit second uplink data and feedback information corresponding to the first downlink data.

[0349] As shown in FIG. 14, the first transmission resource transmits first indication information, and the first indication information is used to indicate that the second transmission resource transmits the first downlink data and the DCI. The second transmission resource simultaneously transmits the DCI and the first downlink data, and the DCI is used to indicate an uplink transmission resource, and the uplink transmission resource is used to transmit HARQ feedback information, and the HARQ feedback information is information corresponding to the first downlink data.

[0350] In some embodiments, the network device configures a set of PUCCH resources, and the first PUCCH resource in the set of PUCCH resources is indicated by index information carried by the DCI.

[0351] Optionally, the DCI is used to indicate a time offset of the first PUCCH resource relative to the second transmission resource, or is used to indicate a time offset of the first PUCCH resource relative to a transmission resource corresponding to the DCI, or is used to indicate a time offset between the first PUCCH resource and a transmission resource corresponding to the first downlink data.

[0352] 1.9 A set of transmission resources includes a first transmission resource and a third transmission resource:

[0353] In some embodiments, the terminal device receives the first transmission resource and the third transmission resource configured by the network device, and the first transmission resource and the third transmission resource have a corresponding relationship. Optionally, the corresponding relationship between the first transmission resource and the third transmission resource is one-to-one.

[0354] The positional relationship between the first transmission resource and the third transmission resource is described in the embodiment of FIG. 4, which is not described here.

[0355] In some embodiments, the first indication information is used to indicate at least one of the following modes:

[0356] 1.9.1 Mode 1: indicating that no transmission is performed on the third transmission resource.

[0357] In a case where the first indication information indicates no transmission on the third transmission resource, the terminal device does not need to perform transmission on the third transmission resource.

[0358] 1.9.2. Mode 2: The first indication information indicates transmission of the first uplink data on the third transmission resource.

[0359] In some embodiments, the first uplink data is transmitted on the third transmission resource based on the first indication information.

[0360] In a case where the first indication information indicates transmission of the first uplink data on the third transmission resource, the terminal device transmits the first uplink data on the third transmission resource. For specific implementation details, reference is made to Mode 6 of 1.3.6 above, which will not be repeated here.

[0361] 1.9.3. The first indication information is used to indicate a first value:

[0362] In some embodiments, the first indication information is used to indicate the first value, and the first value is associated with transmission content.

[0363] For example, the first indication information is used to indicate 2 values of the first value, and the correspondence between the first value and the transmission content is as shown in Table 8:

[0364] Table 8

[0365] For example, when the first value is 0, the corresponding transmission content is “no transmission on the third transmission resource”; when the first value is 1, the corresponding transmission content is “transmission of the first uplink data on the third transmission resource”.

[0366] 1.9.4. The first indication information is carried by a sequence:

[0367] In some embodiments, the first indication information is carried by a sequence, and a sequence index of the sequence is associated with transmission content.

[0368] For example, the first indication information is carried by 2 sequences, and the correspondence between the sequence index and the transmission content is as shown in Table 9:

[0369] Table 9

[0370] For example, when the sequence index is 0, the corresponding transmission content is “no transmission on the third transmission resource”; when the sequence index is 1, the corresponding transmission content is “transmission of the first uplink data on the third transmission resource”.

[0397] 1.10.12 The first indication information is used to indicate the first value:

[0398] In some embodiments, the first indication information is used to indicate the first value, and the first value is associated with the transmission content.

[0399] 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 10:

[0400] Table 10

[0401] For example, when the first value is 0, the corresponding transmission content is "no transmission (or not involved) on the second transmission resource, and no transmission (or not involved) on the third transmission resource"; when the first value is 1, the corresponding transmission content is "transmission of PDCCH or DCI on the second transmission resource, and no transmission (or not involved) on the third transmission resource"; when the first value is 2, the corresponding transmission content is "transmission of first downlink data on the second transmission resource, and no transmission (or not involved) on the third transmission resource"; when the first value is 3, the corresponding transmission content is "transmission of first downlink data on the second transmission resource, and transmission of feedback information on the third transmission resource"; when the first value is 4, the corresponding transmission content is "transmission of first downlink data on the second transmission resource, and transmission of first uplink data and feedback information on the third transmission resource"; when the first value is 5, the corresponding transmission content is "no transmission (or not involved) on the second transmission resource, and transmission of first uplink data on the third transmission resource"; when the first value is 6, the corresponding transmission content is "transmission of DCI and first downlink data on the second transmission resource, and no transmission (or not involved) on the third transmission resource"; when the first value is 7, the corresponding transmission content is "transmission of first downlink data on the second transmission resource, and transmission of first uplink data on the third transmission resource"; when the first value is 8, the corresponding transmission content is "transmission of DCI and first downlink data on the second transmission resource, and transmission of first uplink data on the third transmission resource"; when the first value is 9, the corresponding transmission content is "transmission of DCI and first downlink data on the second transmission resource, and transmission of feedback information on the third transmission resource"; when the first value is 10, the corresponding transmission content is "transmission of DCI and first downlink data on the second transmission resource, and transmission of first uplink data and feedback information on the third transmission resource".

[0404] 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 11.

[0405] Table 11

[0406] For example, when the sequence index is 0, the corresponding transmission content is "no transmission (or not involved) on the second transmission resource, and no transmission (or not involved) on the third transmission resource"; when the sequence index is 1, the corresponding transmission content is "transmission of PDCCH or DCI on the second transmission resource, and no transmission (or not involved) on the third transmission resource"; when the sequence index is 2, the corresponding transmission content is "transmission of first downlink data on the second transmission resource, and no transmission (or not involved) on the third transmission resource"; when the sequence index is 3, the corresponding transmission content is "transmission of first downlink data on the second transmission resource, and transmission of feedback information on the third transmission resource"; when the sequence index is 4, the corresponding transmission content is "transmission of first downlink data on the second transmission resource, and transmission of first uplink data and feedback information on the third transmission resource"; when the sequence index is 5, the corresponding transmission content is "no transmission (or not involved) on the second transmission resource, and transmission of first uplink data on the third transmission resource"; when the sequence index is 6, the corresponding transmission content is "transmission of DCI and first downlink data on the second transmission resource, and no transmission (or not involved) on the third transmission resource"; when the sequence index is 7, the corresponding transmission content is "transmission of first downlink data on the second transmission resource, and transmission of first uplink data on the third transmission resource"; when the sequence index is 8, the corresponding transmission content is "transmission of DCI and first downlink data on the second transmission resource, and transmission of first uplink data on the third transmission resource"; when the sequence index is 9, the corresponding transmission content is "transmission of DCI and first downlink data on the second transmission resource, and transmission of feedback information on the third transmission resource"; when the sequence index is 10, the corresponding transmission content is "transmission of DCI and first downlink data on the second transmission resource, and transmission of first uplink data and feedback information on the third transmission resource".

[0407] In summary, the method provided in the embodiment performs at least one of downlink transmission and uplink transmission on the subsequent other transmission resources based on the first indication information on the first transmission resource. Since the first transmission resource and the other transmission resources are a group of transmission resources associated with each other, only the first indication information on the first transmission resource needs to be detected for each group of transmission resources, and the transmission behavior on the subsequent other transmission resources can be determined based on the first indication information. In a group of transmission resources, blind detection is not required or the complexity of blind detection is reduced, and the effect of energy saving and consumption reduction is achieved.

[0408] The method provided in the embodiment also improves the resource utilization efficiency and data transmission efficiency of the second transmission resource by simultaneously receiving the DCI and the first downlink data on the second transmission resource.

[0409] FIG. 15 shows a flowchart of a transmission method provided in an example embodiment of the present application, the method being performed by a network device, and the method comprising:

[0410] Step 1510: transmitting first indication information on a first transmission resource in a set of transmission resources.

[0411] The set of transmission resources comprises the first transmission resource and other transmission resources, the other transmission resources being at least one transmission resource in the set of transmission resources other than the first transmission resource, the first indication information being used to indicate transmission content on the other transmission resources, and at least two transmission resources in the set of transmission resources having a corresponding relationship.

[0412] In some embodiments, the first indication information is indicated in a sequence manner, or is understood to be carried by a sequence, and a sequence type used to carry the first indication information comprises at least one of a complex (vector) sequence and a real sequence.

[0413] The complex (vector) sequence comprises at least one of a CAZAC sequence and a ZC (Zaddoff Chu) sequence, and the real sequence comprises at least one of a PN sequence, a Gold sequence, an m sequence, and a Hadamard sequence.

[0414] In some embodiments, the first indication information is carried by a first sequence, and a length of the first sequence is determined based on at least one of the following manners: based on protocol predefinition information; based on configuration information transmitted by the network; and based on a frequency domain resource size included by the first transmission resource.

[0415] For example, the first transmission resource comprises K subcarriers or REs, and the sequence length L is a largest prime number less than or equal to K, or is a largest prime number less than or equal to (K / A), A being a preset positive integer, for example, A=2 or 4.

[0416] 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.

[0417] In some embodiments, the first indication information is carried by first information associated with the first sequence, and the first information is determined based on at least one of the following information: a length corresponding to the first sequence; frequency domain resource information corresponding to the first sequence; time domain resource information corresponding to the first sequence; a sequence index corresponding to the first sequence; and a sequence group index corresponding to the first sequence.

[0418] For example, different lengths corresponding to the first sequence respectively correspond to different values or different states or different sequences, thereby indicating different transmission contents on other transmission resources.

[0419] For example, different frequency domain resources corresponding to the first sequence respectively correspond to different values or different states or different sequences, thereby indicating different transmission contents on other transmission resources.

[0420] For example, different time domain resources corresponding to the first sequence respectively correspond to different values or different states or different sequences, thereby indicating different transmission contents on other transmission resources.

[0421] For example, different sequence groups corresponding to the first sequence respectively correspond to different values or different states or different sequences, thereby indicating different transmission contents on other transmission resources.

[0422] In some embodiments, the transmission content on the other transmission resources is determined based on different first information associated with the first indication information. It can be understood that the transmission content on the other transmission resources is indicated based on different first information associated with the first indication information.

[0423] 2.1 Optionally, the following five different indication manners can be used to indicate the transmission content on the other transmission resources.

[0424] Indication manner one: indicating the transmission content on the other transmission resources based on the length corresponding to the first sequence;

[0425] Indication manner two: indicating the transmission content on the other transmission resources based on the frequency domain resource corresponding to the first sequence;

[0426] Indication manner three: indicating the transmission content on the other transmission resources based on the time domain resource corresponding to the first sequence;

[0427] Indication manner four: indicating the transmission content on the other transmission resources based on the sequence index corresponding to the first sequence;

[0428] Indication manner five: indicating the transmission content on the other transmission resources based on the sequence group index corresponding to the first sequence.

[0429] In some embodiments, the other transmission resources include at least one of a second transmission resource and a third transmission resource, and the transmission content on the other transmission resources includes at least one of the following:

[0430] No transmission on the second transmission resource; transmission of the DCI or the PDCCH on the second transmission resource; transmission of the first downlink data on the second transmission resource; transmission of the DCI and the first downlink data on the second transmission resource; no transmission on the third transmission resource; transmission of the feedback information on the third transmission resource; transmission of the first uplink data on the third transmission resource; and transmission of the feedback information and the first uplink data on the third transmission resource.

[0431] 2.1.1 For the indication manner one: the content of the transmission on the other transmission resource is indicated based on the length corresponding to the first sequence.

[0432] For specific implementation details, refer to 1.1.1 of the embodiment of FIG. 2, which will not be repeated here.

[0433] 2.1.2 For the indication manner two: the content of the transmission on the other transmission resource is indicated based on the frequency domain resource corresponding to the first sequence.

[0434] For specific implementation details, refer to 1.1.2 of the embodiment of FIG. 2, which will not be repeated here.

[0435] 2.1.3 For the indication manner three: the content of the transmission on the other transmission resource is indicated based on the time domain resource corresponding to the first sequence.

[0436] For specific implementation details, refer to 1.1.3 of the embodiment of FIG. 2, which will not be repeated here.

[0437] 2.1.4 For the indication manner four: the content of the transmission on the other transmission resource is indicated based on the sequence index corresponding to the first sequence.

[0438] For specific implementation details, refer to 1.1.4 of the embodiment of FIG. 2, which will not be repeated here.

[0439] 2.1.5 For the indication manner five: the content of the transmission on the other transmission resource is indicated based on the sequence group index corresponding to the first sequence.

[0440] For specific implementation details, refer to 1.1.5 of the embodiment of FIG. 2, which will not be repeated here.

[0441] Step 1520: based on the first indication information, performing at least one of the downlink transmission and the uplink transmission on the other transmission resource in the group of transmission resources.

[0442] In some embodiments, the other transmission resource includes: at least one second transmission resource; and / or, at least one third transmission resource; wherein the second transmission resource is used for the downlink transmission, and the third transmission resource is used for the uplink transmission.

[0443] In some embodiments, the method further comprises: sending first configuration information, the first configuration information being used for configuring one or more groups of transmission resources, the first configuration information being carried in a system information block or RRC signaling. Optionally, the first configuration information configures at least one group of transmission resources in a semi-static manner.

[0444] By carrying the first configuration information in the system information block or the RRC signaling, no additional signaling is required, signaling transmission overhead is reduced, and the terminal device can be quickly configured after connecting to the network device, thereby accelerating the process of accessing the network. In addition, the terminal device can be configured during the system information update process, and the terminal device can be more flexibly managed and adjusted.

[0445] Optionally, the first configuration information is determined based on protocol predefined information, or is determined based on configuration information sent by the network device.

[0446] In some embodiments, by the first configuration information described above, the network device configures the first transmission resource and the second transmission resource for the terminal device, or configures the first transmission resource and the third transmission resource for the terminal device, or configures the first transmission resource, the second transmission resource, and the third transmission resource for the terminal device. In a group of transmission resources, the first transmission resource, the second transmission resource, and the third transmission resource can each be multiple. The following embodiments mainly take other transmission resources including one second transmission resource and one third transmission resource as an example.

[0447] 2.2 Corresponding relationship and positional relationship between transmission resources:

[0448] In some embodiments, the corresponding relationship can also be referred to as an association relationship, and the corresponding relationship includes at least one of the following:

[0449] (1) The corresponding relationship between the first transmission resource and the second transmission resource is one-to-one or many-to-one; wherein one-to-one means that one first transmission resource corresponds to one second transmission resource, and many-to-one means that multiple first transmission resources correspond to the same second transmission resource;

[0450] (2) The corresponding relationship between the first transmission resource and the third transmission resource is one-to-one or many-to-one; wherein one-to-one means that one first transmission resource corresponds to one third transmission resource, and many-to-one means that multiple first transmission resources correspond to the same third transmission resource;

[0451] (3) The corresponding relationship between the second transmission resource and the third transmission resource is one-to-one or many-to-one; wherein one-to-one means that one second transmission resource corresponds to one third transmission resource, and many-to-one means that multiple second transmission resources correspond to the same third transmission resource.

[0452] In some embodiments, the location of the second transmission resource is determined based on the location of the first transmission resource; or, there is a predefined relationship between the location of the second transmission resource and the location of the first transmission resource based on a communication protocol; or, there is a preconfigured relationship between the location of the second transmission resource and the location of the first transmission resource based on a network.

[0453] In some embodiments, the location of the third transmission resource is determined based on the location of the first transmission resource; or, there is a predefined relationship between the location of the third transmission resource and the location of the first transmission resource based on a communication protocol; or, there is a preconfigured relationship between the location of the third transmission resource and the location of the first transmission resource based on a network.

[0454] In some embodiments, the location of the third transmission resource is determined based on the location of the second transmission resource; or, there is a predefined relationship between the location of the third transmission resource and the location of the second transmission resource based on a communication protocol; or, there is a preconfigured relationship between the location of the third transmission resource and the location of the second transmission resource based on a network.

[0455] By way of example and not limitation, the location relationship between the first transmission resource and the second transmission resource includes at least one of the following:

[0456] The first transmission resource and the second transmission resource are not adjacent in time domain; the first transmission resource and the second transmission resource are adjacent in time domain; 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.

[0457] The first transmission resource and the second transmission resource are adjacent in time domain 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.

[0458] In some embodiments, the location of the third transmission resource is determined based on the location of the second transmission resource; or, there is a predefined relationship between the location of the third transmission resource and the location of the second transmission resource based on a communication protocol; or, there is a preconfigured relationship between the location of the third transmission resource and the location of the second transmission resource based on a network.

[0459] By way of example and not limitation, the location relationship between the third transmission resource and the second transmission resource includes at least one of the following:

[0460] The third transmission resource is not adjacent in time domain to the second transmission resource; the third transmission resource is adjacent in time domain to the second transmission resource; a frequency domain starting position of the third transmission resource is the same as a frequency domain starting position of the second transmission resource; a frequency domain center position of the third transmission resource is the same as a frequency domain center position of the second transmission resource; and a frequency domain ending position of the third transmission resource is the same as a frequency domain ending position of the second transmission resource.

[0461] The third transmission resource is adjacent in time domain to the second transmission resource.

[0462] In some embodiments, a time domain starting position of the first transmission resource is not later than a time domain starting position of the second transmission resource, and the time domain starting position of the second transmission resource is not later than a time domain starting position of the third transmission resource. For example, when the third transmission resource is used to carry the HARQ feedback of the downlink data on the second transmission resource, the time domain starting position of the third transmission resource is slightly later than the time domain starting position of the second transmission resource, because a processing time needs to be reserved for the terminal device.

[0463] The specific implementation details are described below with reference to the embodiment 1.2 of FIG. 2, which will not be repeated here.

[0464] 2.3 The first indication information:

[0467] The downlink control channel is used to carry the DCI, the downlink shared channel or the downlink data channel is used to carry the first downlink data, the uplink shared channel or the uplink data channel is used to carry the first uplink data, and the feedback information includes an acknowledgement feedback (ACK) or a negative acknowledgement feedback (NACK) corresponding to the first downlink data or the downlink shared channel or the downlink data channel transmitted on the second transmission resource, and / or an ACK or a NACK corresponding to second downlink data or a downlink shared channel or a downlink data channel transmitted on a fourth transmission resource. The fourth transmission resource is a downlink transmission resource scheduled by the DCI carried on the second transmission resource.

[0468] In some embodiments, the feedback information comprises at least one of the following: acknowledgement feedback or negative acknowledgement feedback; RSRQ obtained based on measurement of a reference signal; RSRP; CSI; PMI; RI; reference signal index information; LRR.

[0469] In some embodiments, the first indication information is further used to indicate whether there is transmission on the other transmission resource; in the case that the first indication information indicates that there is transmission on the other transmission resource, the first indication information is used to indicate the transmission content on the other transmission resource.

[0470] In some embodiments, the first indication information is used to indicate whether there is transmission on the (each) second transmission resource and / or the (each) third transmission resource; in the case that the first indication information indicates that there is transmission on the second transmission resource, the first indication information is used to indicate the transmission content on the second transmission resource; in the case that the first indication information indicates that there is transmission on the third transmission resource, the first indication information is used to indicate the transmission content on the third transmission resource.

[0471] In some embodiments, the first indication information is used to indicate the transmission content on the other transmission resource. If the first indication information indicates the transmission content on the second transmission resource, it can be determined that there is transmission on the second transmission resource; if the first indication information indicates the transmission content on the third transmission resource, it can be determined that there is transmission on the third transmission resource.

[0472] By indicating whether there is transmission on the other transmission resource through the first indication information, in the case that the second transmission resource is indicated to have no transmission, the terminal device does not need to detect on the second transmission resource, and in the case that the third transmission resource is indicated to have no transmission, the terminal device does not need to transmit on the third transmission resource, thereby reducing the energy consumption of the terminal device.

[0473] FIG. 5 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:

[0474] 2.3.1 Mode 1: indicating no transmission on the second transmission resource.

[0475] In the case that the first indication information indicates no transmission on the second transmission resource, the network device does not send the DCI or the first downlink data, and the terminal device does not need to detect on the second transmission resource.

[0476] Optionally, the terminal device determines a first value or a first state or a first sequence based on the first indication information, and determines no transmission on the second transmission resource based on the first value or the first state or the first sequence.

[0477] Wherein, the first value is a bit value or a group of bit values, such as the value of the first value is 1 or 0; the first state is an on state or an off state, which can be represented by high or low level or high or low energy, or can be represented by bit value; the first sequence is a sequence for representing the first indication information, for example, a ZC sequence. The representation principles of the second value, the second state, the second sequence, the third value, the third state, the third sequence and other values, states and sequences in the following are the same, and will not be repeated.

[0478] 2.3.2 Mode 2: Indicating that the DCI or PDCCH is transmitted on the second transmission resource.

[0479] In some embodiments, the DCI or PDCCH is transmitted on the second transmission resource.

[0480] The network device transmits the DCI or PDCCH on the second transmission resource, so that the terminal device only needs to detect the PDCCH on the second transmission resource, such as a search space 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.

[0481] By indicating that the DCI or PDCCH is transmitted on the second transmission resource in the first indication information, the terminal device only needs to detect the PDCCH on the second transmission resource, and does not need to continuously detect the PDCCH on all second transmission resources, which reduces the complexity of blind detection and achieves the effect of energy saving and consumption reduction.

[0482] Optionally, the DCI is carried on the PDCCH or the PDSCH. FIG. 6 shows a schematic diagram of a DCI transmission mode provided by an exemplary embodiment of the present application.

[0483] In some embodiments, the DCI is carried by the MAC CE, and the MAC CE is carried by the PDSCH.

[0484] For example, in (a) of FIG. 6, the MAC CE is carried by the PDSCH, and the MAC CE carries the DCI; in (b) of FIG. 6, the DCI is carried by the PDCCH.

[0485] Optionally, the terminal device determines the second value or the second state or the second sequence based on the first indication information, and determines that the DCI or PDCCH is transmitted on the second transmission resource based on the second value or the second state or the second sequence.

[0486] In some embodiments, based on the first indication information, the network device transmits the DCI or the downlink control channel on the second transmission resource, and transmits the second downlink data on the fourth transmission resource, which is indicated by the DCI or the downlink control channel on the second transmission resource.

[0487] In some embodiments, the method further comprises: based on the first indication information, receiving feedback information corresponding to the second downlink data transmitted by the terminal device on the third transmission resource.

[0488] 2.3.3 Mode 3: Indicating the second transmission resource to transmit the first downlink data.

[0489] In some embodiments, the network device transmits the first downlink data on the second transmission resource based on the first indication information. Optionally, the first downlink data is carried by a PDSCH.

[0490] Optionally, the terminal device determines a third value or a third state or a third sequence based on the first indication information, and determines to transmit the first downlink data on the second transmission resource based on the third value or the third state or the third sequence.

[0491] Since the first indication information does not carry resource scheduling information, the transmission parameters corresponding to the first downlink data are determined based on protocol pre-defined information or network configuration information. In some embodiments, the transmission parameters include at least one of the following:

[0492] a modulation mode or an 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; a layer number corresponding to the first downlink data; antenna port information corresponding to the first downlink data; DMRS information corresponding to the first downlink data;

[0493] The TBS can be configured by the network. 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.

[0494] Optionally, the DMRS information corresponding to the first downlink data is determined by 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; DMRS sequence initialization information.

[0495] In some embodiments, the first downlink data corresponds to small data packet transmission. Small data packet transmission can be understood as a transmission block size smaller than or equal to a threshold value, which is determined based on protocol pre-defined information or network configuration information.

[0496] 2.3.4 Mode 4: Indicating the second transmission resource to transmit the first downlink data, and the third transmission resource to transmit the feedback information.

[0497] In some embodiments, the network device transmits the first downlink data on the second transmission resource based on the first indication information, and receives feedback information corresponding to the first downlink data transmitted by the terminal device on the third transmission resource.

[0498] The network device receives the feedback information, such as HARQ information, transmitted by the terminal device on the third transmission resource, and the HARQ information is used to indicate whether the first downlink data is correctly received by the terminal device, and the HARQ information includes ACK or NACK.

[0499] Optionally, the terminal device determines a fourth value or a fourth state or a fourth sequence based on the first indication information, and determines to transmit the first downlink data on the second transmission resource and the feedback information on the third transmission resource based on the fourth value or the fourth state or the fourth sequence.

[0500] Since there is a corresponding relationship between the first transmission resource and the third transmission resource, or between the second transmission resource and the third transmission resource, the terminal device can determine the third transmission resource based on the first transmission resource or the second transmission resource, and transmit the feedback information, such as HARQ feedback information ACK or NACK, corresponding to the first downlink data on the third transmission resource.

[0501] In some embodiments, the feedback information includes at least one of the following: HARQ information; PMI information; RI information; CSI; reference signal index information; LRR, and specific feedback information can be determined based on network configuration information or the first indication information.

[0502] Optionally, the feedback information is carried by PUCCH, and the PUCCH format and / or PUCCH resource are determined by network configuration information or the first indication information.

[0503] In some embodiments, in the case where a plurality of second transmission resources correspond to one third transmission resource, the third transmission resource is used to transmit feedback information corresponding to the first downlink data transmitted by the plurality of second transmission resources.

[0504] The second transmission resource and the third transmission resource are in a many-to-one corresponding relationship, that is, n (n is greater than 1) second transmission resources correspond to one third transmission resource, and at this time the third transmission resource is used to transmit feedback information corresponding to the first downlink data transmitted by the n second transmission resources.

[0505] In some embodiments, the feedback mode includes at least one of the following:

[0506] Feedback mode 1: n feedback information bundling feedback: performing bit-wise operation or bit-or operation on the feedback information corresponding to the first downlink data transmitted on the n second transmission resources, obtaining 1-bit information, and feeding back through the 1-bit information.

[0507] Feedback mode 2: the feedback information includes n information fields (n bits), respectively corresponding to the first downlink data on the n second transmission resources.

[0508] If the terminal device detects the first downlink data on the i-th second transmission resource (success or failure), the terminal device feeds back ACK or NACK on the i-th bit; if the terminal device does not detect the first downlink data on the i-th second transmission resource, the terminal device does not feed back (for example, fills in a specified character NULL) or feeds back NACK or ACK on the i-th bit.

[0509] In some embodiments, if the first downlink data includes one transport block or codeword, the feedback information corresponds to 1 bit; if the first downlink data includes m transport blocks or codewords (m is greater than or equal to 2), the feedback information corresponds to m bits, or the feedback information corresponds to 1 bit, that is, the bit-wise operation or bit-or operation is performed on all the feedback information corresponding to the m transport blocks or codewords, and 1-bit feedback information is obtained.

[0510] By way of example but not limitation, the feedback information corresponds to 1 bit, and the value of the 1 bit is determined based on the bit-wise operation or bit-or operation of the feedback information corresponding to the first downlink data transmitted on the plurality of second transmission resources, and the 1 bit is used to indicate positive acknowledgement or negative acknowledgement.

[0511] By way of example but not limitation, the feedback information corresponds to n bits, the i-th bit corresponds to the feedback information of the first downlink data transmitted on the i-th second transmission resource, and the feedback information includes positive acknowledgement or negative acknowledgement; wherein the plurality of second transmission resources includes n second transmission resources, i and n are positive integers, and i is less than or equal to n.

[0512] Optionally, in the case where the first downlink data is not detected on the i-th second transmission resource, the i-th bit is used to indicate negative feedback or positive feedback or no feedback.

[0513] In the case where the feedback information corresponds to 1 bit, the transmission resources occupied by the feedback information can be reduced, and the overhead can be reduced; in the case where the feedback information corresponds to n bits, it can be more accurate and specific to feed back whether the first downlink data is detected on the n second transmission resources.

[0514] The specific implementation details are referred to 1.3.4 of the embodiment of FIG. 2, which will not be described here.

[0515] 2.3.5 Mode 5: indicating that the second transmission resource is used to transmit the first downlink data, and the third transmission resource is used to transmit the feedback information and / or the first uplink data.

[0516] In the case where the first indication information indicates that the second transmission resource is used to transmit the first downlink data, and the third transmission resource is used to transmit the feedback information and / or the first uplink data, the network device sends the first downlink data on the second transmission resource, and receives the feedback information and / or the first uplink data sent by the terminal device on the third transmission resource. The feedback information is used to indicate whether the first downlink data is correctly received by the terminal device.

[0518] In some embodiments, the feedback information and the first uplink data are resource multiplexed, the feedback information is carried by a MAC CE, and the MAC CE and the first uplink data are carried by a PUSCH; the first uplink data is carried by a PUSCH, and the feedback information and the PUSCH are resource multiplexed, i.e., the feedback information and the PUSCH correspond to different resources in the third transmission resource.

[0519] Optionally, the first uplink data corresponds to small data packet transmission. The small data packet transmission can be understood as a transmission block size less than or equal to a threshold value, and the threshold value is determined based on protocol definition information or network configuration information. Since the first indication information does not carry resource scheduling information, the transmission parameters corresponding to the first uplink data are determined based on protocol definition information or network configuration information.

[0520] 2.3.6 Mode 6: indicating that the third transmission resource is used to transmit the first uplink data.

[0521] In some embodiments, the network device receives the first uplink data sent by the terminal device on the third transmission resource based on the first indication information. Optionally, the first uplink data is carried by a PUSCH.

[0522] Optionally, the terminal device determines a sixth value or a sixth state or a sixth sequence based on the first indication information, and determines to transmit the first uplink data on the third transmission resource based on the sixth value or the sixth state or the sixth sequence.

[0523] In some embodiments, the network device configures the third transmission resource for the terminal device to perform uplink transmission, and sends the first indication information to the terminal device through the first transmission resource, to indicate whether the terminal device can perform uplink transmission on the third transmission resource.

[0524] For example, the network device configures a third transmission resource for the terminal device, the third transmission resource is an uplink configured grant resource, including a type 1 uplink configured grant resource or a type 2 uplink configured grant resource, or an uplink configured grant resource of other types, and when the terminal device receives the first indication information sent by the network device and the first indication information indicates the sixth value, the terminal device can send the first uplink data by using the third transmission resource.

[0525] Since the first indication information does not carry resource scheduling information, the transmission parameters corresponding to the first uplink data are determined based on protocol predefined information or network configuration information.

[0553] In some embodiments, when the set of transmission resources is common transmission resources shared by multiple terminal devices or group transmission resources shared by a group of terminal devices, the other transmission resources in the set of transmission resources include a second transmission resource, the second transmission resource is used for transmission of common DCI and / or common downlink data, the common DCI and / or common downlink data is used for transmission of at least one of the following information: broadcast information, system information, paging information, random access response information.

[0554] In some embodiments, when the set of transmission resources is common transmission resources shared by multiple terminal devices or group transmission resources shared by a group of terminal devices, the other transmission resources in the set of transmission resources include a third transmission resource, the third transmission resource is used for transmission of a random access sequence by the terminal device.

[0555] The network device configures the same first transmission resource and the same second transmission resource for the plurality of terminal devices, i.e., the first transmission resource and the second transmission resource are common transmission resources shared by the plurality of terminal devices; the network device configures the same sequence for the plurality of terminal devices, or the network device configures a respective 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.

[0576] In some embodiments, the second transmission resource is used to transmit the downlink data, and the downlink data is carried by a PDSCH.

[0577] Since the transmission resource indication information and the transmission parameter indication information are not included in the first indication information, the transmission parameters corresponding to the downlink data are determined based on protocol predefined information or network configuration information.

[0593] To sum up, the method provided in the embodiment enables the terminal device to perform at least one of the downlink transmission and the uplink transmission on the subsequent other transmission resources based on the first indication information, since the first transmission resource and the other transmission resources are a set of transmission resources that are associated, the terminal device only needs to detect the first indication information on the first transmission resource for each set of transmission resources, and then determine the transmission behavior on the subsequent other transmission resources based on the first indication information, and no blind detection or reduced complexity of blind detection is needed in the set of transmission resources, thereby achieving the effect of energy saving and consumption reduction.

[0594] The method provided in the embodiment also improves the resource utilization efficiency and the data transmission efficiency of the second transmission resource by simultaneously transmitting the DCI and the first downlink data on the second transmission resource.

[0650] For specific implementation details, refer to 1.2 of the embodiment of FIG. 2, which will not be repeated here.

[0657] In a possible design of the embodiment, the first indication information is used for indicating whether there is transmission on the second transmission resource and / or the third transmission resource; in a case where the first indication information indicates that there is transmission on the second transmission resource, the first indication information is used for indicating transmission content on the second transmission resource; in a case where the first indication information indicates that there is transmission on the third transmission resource, the first indication information is used for indicating transmission content on the third transmission resource.

[0660] FIG. 5 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 manners:

[0661] 3.3.1 Manner 1: indicating no transmission on the second transmission resource.

[0662] In a case that the first indication information indicates no transmission on the second transmission resource, the first transmission device does not need to detect on the second transmission resource.

[0663] Optionally, the determining module 1630 is configured to determine a first value or a first state or a first sequence based on the first indication information, and determine no transmission on the second transmission resource based on the first value or the first state or the first sequence.

[0664] 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 or an off state, which can be represented by a high or low level or a high or low energy, or can be represented by a bit value; and the first sequence is a sequence for representing the first indication information, such as a ZC sequence. The principles of representing the second value, the second state, the second sequence, the third value, the third state, the third sequence and other values, states and sequences are the same, and will not be described herein.

[0665] 3.3.2 Manner 2: indicating transmission of DCI or PDCCH on the second transmission resource.

[0666] In a possible design of the embodiment, the transceiver module 1620 is configured to receive DCI or PDCCH on the second transmission resource based on the first indication information.

[0667] In a case that the first indication information indicates transmission of DCI or PDCCH on the second transmission resource, the first transmission device detects DCI or PDCCH on the second transmission resource. For example, a search space is configured on the second transmission resource, and the first transmission device detects DCI or PDCCH on the search space. In a possible design of the embodiment, the search space has a low detection complexity, for example, 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 first transmission device only needs to perform PDCCH detection at most 2 times in the search space.

[0668] By indicating that the PDCCH needs to be detected on the second transmission resource only in the case that the DCI or the PDCCH is transmitted on the second transmission resource, the detection complexity is reduced, and the effect of saving energy and reducing consumption is achieved.

[0669] Optionally, the DCI is carried on the PDCCH or the PDSCH. FIG. 6 shows a schematic diagram of a DCI transmission manner provided by an example embodiment of the present application.

[0670] In a possible design of the embodiment, the DCI is carried by a MAC CE, and the MAC CE is carried by the PDSCH.

[0671] For example, in (a) of FIG. 6, the MAC CE is carried by the PDSCH, and the MAC CE carries the DCI; in (b) of FIG. 6, the DCI is carried by the PDCCH.

[0672] Optionally, the determining module 1630 is configured to determine the second value or the second state or the second sequence based on the first indication information, and determine that the DCI or the PDCCH is transmitted on the second transmission resource based on the second value or the second state or the second sequence.

[0673] In a possible design of the embodiment, the transceiver module 1620 is configured to receive the DCI or the downlink control channel on the second transmission resource and receive the second downlink data on the fourth transmission resource based on the first indication information, where the fourth transmission resource is indicated by the DCI or the downlink control channel on the second transmission resource.

[0674] In a possible design of the embodiment, the transceiver module 1620 is configured to transmit feedback information corresponding to the second downlink data on the third transmission resource based on the first indication information.

[0675] 3.3.3. Mode 3: Indicating that the second transmission resource transmits the first downlink data.

[0676] In a possible design of the embodiment, the transceiver module 1620 is configured to receive the first downlink data on the second transmission resource based on the first indication information. Optionally, in the case that the second transmission resource is not indicated to transmit the first downlink data, the first downlink data does not need to be detected on the second transmission resource.

[0677] In the case that the first indication information indicates that the second transmission resource transmits the first downlink data, the first transmission device detects the first downlink data on the second transmission resource.

[0678] Optionally, the first downlink data is carried by the PDSCH.

[0679] Optionally, the determining module 1630 is configured to determine the third value or the third state or the third sequence based on the first indication information, and determine the first downlink data to be transmitted on the second transmission resource based on the third value or the third state or the third sequence.

[0680] Since the first indication information does not carry resource scheduling information, the transmission parameter corresponding to the first downlink data is determined based on protocol predefined information or network configuration information. In a possible design of the embodiment, the transmission parameter includes at least one of the following:

[0681] a modulation mode or an 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 layer number corresponding to the first downlink data; antenna port information corresponding to the first downlink data; DMRS information corresponding to the first downlink data.

[0682] The TBS can be configured by the network. 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.

[0683] Optionally, the DMRS information corresponding to the first downlink data is determined by network configuration information. 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; DMRS sequence initialization information.

[0684] In a possible design of the embodiment, the first downlink data corresponds to small data packet transmission. The small data packet transmission can be understood as a transmission block size smaller than or equal to a threshold value, and the threshold value is determined based on protocol predefined information or network configuration information.

[0685] 3.3.4 Mode 4: The first indication information indicates that the first downlink data is transmitted on the second transmission resource, and the feedback information is transmitted on the third transmission resource.

[0686] In a possible design of the embodiment, the transceiver module 1620 is configured to receive the first downlink data on the second transmission resource based on the first indication information, and transmit the feedback information corresponding to the first downlink data on the third transmission resource.

[0687] In the case where the first indication information indicates that the first downlink data is transmitted on the second transmission resource and the feedback information is transmitted on the third transmission resource, the first transmission device detects the first downlink data on the second transmission resource. Optionally, the first downlink data is carried by a PDSCH.

[0688] The first transmission device transmits feedback information, such as HARQ information, on the third transmission resource, where the HARQ information is used to indicate whether the first downlink data is correctly received, and the HARQ information includes ACK or NACK.

[0689] Optionally, the determining module 1630 is configured to determine a fourth value or a fourth state or a fourth sequence based on the first indication information, and determine that the first downlink data is transmitted on the second transmission resource and the feedback information is transmitted on the third transmission resource based on the fourth value or the fourth state or the fourth sequence.

[0690] In a possible design of the embodiment, in a case where the first indication information indicates that the first downlink data is transmitted on the second transmission resource, the first transmission device detects the first downlink data on the second transmission resource and feeds back.

[0691] Since there is a corresponding relationship between the first transmission resource and the third transmission resource, or between the second transmission resource and the third transmission resource, the first transmission device can determine the third transmission resource based on the first transmission resource or the second transmission resource, and transmit feedback information corresponding to the first downlink data on the third transmission resource, such as HARQ feedback information ACK or NACK.

[0692] In a possible design of the embodiment, the feedback information includes at least one of the following: HARQ information; PMI information; RI information; CSI; reference signal index information; and LRR. Which kind of feedback information is specifically fed back can be determined based on network configuration information or the first indication information.

[0693] Optionally, the feedback information is carried by a PUCCH, and a PUCCH format and / or a PUCCH resource are determined based on network configuration information or the first indication information.

[0694] In a possible design of the embodiment, in a case where a plurality of second transmission resources correspond to one third transmission resource, the third transmission resource is used to transmit feedback information corresponding to the first downlink data transmitted on the plurality of second transmission resources.

[0695] The second transmission resource and the third transmission resource are in a many-to-one corresponding relationship, that is, n (n is greater than 1) second transmission resources correspond to one third transmission resource, and the third transmission resource is used to transmit feedback information corresponding to the first downlink data transmitted on the n second transmission resources.

[0696] In a possible design of the embodiment, the feedback manner includes at least one of the following:

[0697] Feedback mode 1: n feedback information bundling feedback: performing bit-wise operation or bit-or operation on the feedback information corresponding to the first downlink data transmitted on the n second transmission resources, obtaining 1-bit information, and feeding back the 1-bit information.

[0698] Feedback mode 2: the feedback information includes n information fields (n bits), respectively corresponding to the first downlink data on the n second transmission resources.

[0699] If the first transmission device detects the first downlink data on the i-th second transmission resource (success or failure), the first transmission device feeds back ACK or NACK on the i-th bit; if the first transmission device does not detect the first downlink data on the i-th second transmission resource, the first transmission device does not feed back (e.g. fills NULL) or feeds back NACK or ACK on the i-th bit.

[0700] In a possible design of the embodiment, if the first downlink data includes one transport block or codeword, the feedback information corresponds to 1 bit; if the first downlink data includes m transport blocks or codewords (m is greater than or equal to 2), the feedback information corresponds to m bits, or the feedback information corresponds to 1 bit, i.e. performing bit-wise operation or bit-or operation on all the feedback information corresponding to the m transport blocks or codewords, obtaining 1-bit feedback information.

[0701] By way of example but not limitation, the feedback information corresponds to 1 bit, and the value of the 1 bit is determined based on bit-wise operation or bit-or operation of the feedback information corresponding to the first downlink data transmitted on the plurality of second transmission resources, and the 1 bit is used to indicate positive acknowledgement or negative acknowledgement.

[0702] By way of example but not limitation, the feedback information corresponds to n bits, the i-th bit corresponds to the feedback information of the first downlink data transmitted on the i-th second transmission resource, and the feedback information includes positive acknowledgement or negative acknowledgement; wherein the plurality of second transmission resources include n second transmission resources, i and n are positive integers, and i is less than or equal to n.

[0703] Optionally, in the case that the first downlink data is not detected on the i-th second transmission resource, the i-th bit is used to indicate negative feedback or positive feedback or no feedback.

[0704] In the case that the feedback information corresponds to 1 bit, the transmission resource occupied by the feedback information can be reduced, and the overhead can be reduced; in the case that the feedback information corresponds to n bits, it can be more accurate and specific to feed back whether the first downlink data is detected on the n second transmission resources.

[0705] For specific implementation details, refer to 1.3.4 of the embodiment of FIG. 2, which will not be described here again.

[0706] 3.3.5 Mode 5: indicating that the second transmission resource is used to transmit the first downlink data, and the third transmission resource is used to transmit the feedback information and / or the first uplink data.

[0707] In the case that the first indication information indicates that the second transmission resource is used to transmit the first downlink data, and the third transmission resource is used to transmit the feedback information and / or the first uplink data, the first transmission device detects the first downlink data on the second transmission resource; and the first transmission device transmits the feedback information and / or the first uplink data on the third transmission resource, the feedback information being used to indicate whether the first downlink data is correctly received.

[0708] Optionally, the determining module 1630 is configured to determine, based on the first indication information, a fifth value or a fifth state or a fifth sequence, and determine, based on the fifth value or the fifth state or the fifth sequence, that the first downlink data is transmitted on the second transmission resource and the feedback information and / or the first uplink data is transmitted on the third transmission resource.

[0709] In a possible design of the embodiment, the feedback information and the first uplink data are resource multiplexed, the feedback information is carried by a MAC CE, and the MAC CE and the first uplink data are carried by a PUSCH; the first uplink data is carried by a PUSCH, and the feedback information and the PUSCH are resource multiplexed, that is, the feedback information and the PUSCH correspond to different resources in the third transmission resource.

[0710] Optionally, the first uplink data corresponds to small data packet transmission. The small data packet transmission can be understood as that a transport block size is smaller than or equal to a threshold value, and the threshold value is determined based on protocol definition information or network configuration information. Since the first indication information does not carry resource scheduling information, the transmission parameter corresponding to the first uplink data is determined based on protocol definition information or network configuration information.

[0711] 3.3.6 Mode 6: indicating that the third transmission resource is used to transmit the first uplink data.

[0712] In a possible design of the embodiment, the transceiver module 1620 is configured to transmit, based on the first indication information, the first uplink data on the third transmission resource.

[0713] In the case that the first indication information indicates that the third transmission resource is used to transmit the first uplink data, the first transmission device transmits the first uplink data on the third transmission resource.

[0714] Optionally, the first uplink data is carried by a PUSCH.

[0715] Optionally, the determining module 1630 is configured to determine, based on the first indication information, a sixth value or a sixth state or a sixth sequence, and determine, based on the sixth value or the sixth state or the sixth sequence, that the first uplink data is transmitted on the third transmission resource.

[0716] In a possible design of the present embodiment, the second transmission apparatus configures a third transmission resource for the first transmission apparatus to perform uplink transmission, and the second transmission apparatus sends first indication information to the first transmission apparatus through the first transmission resource, to indicate whether the first transmission apparatus can perform uplink transmission on the third transmission resource.

[0717] For example, the second transmission apparatus configures a third transmission resource for the first transmission apparatus, the third transmission resource is an uplink configured grant resource, including a type 1 uplink configured grant resource or a type 2 uplink configured grant resource, or an uplink configured grant resource of another type, and when the first indication information sent by the second transmission apparatus to the terminal indicates the sixth value, the terminal can send first uplink data by using the third transmission resource.

[0718] Since the first indication information does not carry resource scheduling information, the transmission parameter corresponding to the first uplink data is determined based on protocol predefined information or network configuration information. In a possible design of the present embodiment, the transmission parameter includes at least one of the following:

[0719] a modulation mode or an MCS level corresponding to the first uplink data; a coding mode corresponding to the first uplink data; a coding rate corresponding to the first uplink data; a layer number corresponding to the first uplink data; antenna port information corresponding to the first uplink data; DMRS information corresponding to the first uplink data;

[0720] The TBS can be configured by the network. If the data packet of the data 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.

[0722] In a possible design of the present embodiment, the first uplink data corresponds to small data packet transmission. The small data packet transmission can be understood as that the transmission block size is smaller than or equal to a threshold value, and the threshold value is determined based on protocol predefined information or network configuration information.

[0723] 3.3.7 Mode 7: Indicating the second transmission resource to transmit DCI and first downlink data.

[0724] In a possible design of the present embodiment, the transceiver 1620 is configured to receive the DCI and the first downlink data simultaneously on the second transmission resource based on the first indication information, or receive the downlink control channel and the first downlink data simultaneously on the second transmission resource based on the first indication information.

[0725] For 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.

[0726] For 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.

[0727] In a possible design of the present embodiment, the transceiver 1620 is configured to receive the second downlink data on the fourth transmission resource, and the fourth transmission resource is indicated by the DCI or the downlink control channel; and transmit the feedback information corresponding to the first downlink data, or the feedback information corresponding to the second downlink data, or the feedback information corresponding to the first downlink data and the second downlink data on the third transmission resource based on the first indication information.

[0728] For example, 1 bit is used to correspond to the feedback information of the first downlink data and the second downlink data, for example, 1 bit is obtained through a bit operation or a bit operation, and the 1 bit is used for feedback; or 2 bits are used to correspond to the feedback information of the first downlink data and the second downlink data respectively.

[0729] By receiving the DCI and the first downlink data simultaneously on the second transmission resource, the resource utilization efficiency and the data transmission efficiency of the second transmission resource are improved; by receiving the second downlink data on the fourth transmission resource, the second downlink data and the DCI are transmitted on different transmission resources, so that the possible channel interference is reduced, and the reliability of data transmission is improved.

[0730] In a possible design of the present embodiment, the DCI is carried by a MAC CE, and the MAC CE and the first downlink data are carried by a PDSCH.

[0731] In a possible design of the present embodiment, the first downlink data is carried by a PDSCH, and the transmission resource used for carrying the DCI and the PDSCH corresponds to different transmission resources on the second transmission resource.

[0732] In a possible design of the present embodiment, the transceiver 1620 is configured to receive the DCI or the downlink control channel on the second transmission resource based on the first indication information, and transmit the second uplink data on the fifth transmission resource, where the fifth transmission resource is indicated by the DCI or the downlink control channel on the second transmission resource; and receive the first downlink data on the second transmission resource based on the first indication information, and transmit the feedback information corresponding to the first downlink data on the third transmission resource.

[0733] By receiving the DCI or the downlink control channel and the first downlink data on the second transmission resource, and transmitting the second uplink data on the fifth transmission resource, the second uplink data and the feedback information corresponding to the first downlink data are transmitted on different transmission resources, which reduces possible channel interference and improves reliability of data transmission.

[0735] 3.4 The first indication information is used to indicate a first value.

[0736] In a possible design of the present embodiment, the first indication information is used to indicate the first value, and the first value is associated with the transmission content.

[0737] Optionally, a correspondence between the first value and the transmission content is determined by protocol predefined information or network configuration information.

[0738] For specific implementation details, refer to 1.4 of the embodiment of FIG. 2, which will not be repeated here.

[0739] 3.5 The first indication information is carried by a sequence.

[0740] In a possible design of the present embodiment, the first indication information is carried by a sequence, and a sequence index of the sequence is associated with the transmission content.

[0741] Optionally, a correspondence between the sequence index and the transmission content is determined by protocol predefined information or network configuration information.

[0742] For specific implementation details, refer to 1.5 of the embodiment of FIG. 2, which will not be repeated here.

[0743] 3.6 A type of a set of transmission resources.

[0744] In a possible design of the embodiment, the set of transmission resources is common transmission resources shared by the multiple first transmission apparatuses; or, the set of transmission resources is group transmission resources shared by a group of the first transmission apparatuses; or, the set of transmission resources is dedicated transmission resources used by one of the first transmission apparatuses.

[0745] In a possible design of the embodiment, when the set of transmission resources is common transmission resources shared by the multiple first transmission apparatuses or group transmission resources shared by a group of the first transmission apparatuses, the other transmission resources in the set of transmission resources include second transmission resources, and the second transmission resources are 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.

[0746] In a possible design of the embodiment, when the set of transmission resources is common transmission resources shared by the multiple first transmission apparatuses or group transmission resources shared by a group of the first transmission apparatuses, the other transmission resources in the set of transmission resources include third transmission resources, and the third transmission resources are used for the first transmission apparatus to transmit a random access sequence.

[0747] The second transmission apparatus configures the same first transmission resource and the same second transmission resource for the multiple first transmission apparatuses, that is, the first transmission resource and the second transmission resource are shared by the multiple first transmission apparatuses; the second transmission apparatus configures the same sequence for the multiple first transmission apparatuses, or configures respective corresponding sequences for the multiple first transmission apparatuses respectively, and the first transmission apparatus detects the first indication information on the first transmission resource based on the configured sequence.

[0748] For example, the second transmission apparatus configures sequence 1 for the first transmission apparatus 1 and the first transmission apparatus 2, and the first transmission apparatus 1 and the first transmission apparatus 2 both detect the first indication information on the first transmission resource based on the sequence 1.

[0749] For example, the second transmission apparatus configures sequence 1 for the first transmission apparatus 1 and sequence 2 for the first transmission apparatus 2, the first transmission apparatus 1 detects the first indication information on the first transmission resource based on the sequence 1, and the first transmission apparatus 2 detects the first indication information on the first transmission resource based on the sequence 2.

[0750] The second transmission apparatus configures a set of transmission resources for transmitting common DCI and / or 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 common downlink data on the second transmission resource.

[0751] In a possible design of the embodiment, the multiple first transmission apparatuses detect whether there is the first indication information on the first transmission resource based on the same common sequence.

[0752] For example, the second transmission apparatus configures the common sequence 1 for the first transmission apparatus 1 and the first transmission apparatus 2, and the first transmission apparatus 1 and the first transmission apparatus 2 detect the first indication information on the first transmission resource based on the common sequence 1.

[0753] If the first transmission apparatus detects the first indication information, the common DCI and / or the common downlink data are detected 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.

[0754] For example, the broadcast information is MIB information, the system information is SIB information, the paging information is Paging information, and the random access response information is RAR information.

[0755] In a possible design of the embodiment, the second transmission apparatus configures a common transmission resource including a common first transmission resource and a common second transmission resource, and the common first transmission resource and the common second transmission resource are used to transmit the common DCI and the common downlink data.

[0756] 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.

[0757] In a possible design of the embodiment, the second transmission apparatus configures a group transmission resource shared by a first transmission apparatus group, 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 and group common downlink data.

[0758] Optionally, the first transmission apparatus group includes all first transmission apparatuses in a cell, and the group first transmission resource and the group second transmission resource can also be referred to as a shared first transmission resource and a shared second transmission resource.

[0759] 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) information, UL transmission cancellation indication information, and wake-up indication information.

[0760] In a possible design of the embodiment, the second transmission device configures, for each of the first transmission devices, user-specific (UE-specific) dedicated first transmission resources and dedicated second transmission resources, respectively, for transmitting user-specific DCI and user-specific downlink data corresponding to each of the first transmission devices.

[0761] In a possible design of the embodiment, the dedicated first transmission resources of different first transmission devices are non-overlapped, completely overlapped, or partially overlapped, and the dedicated second transmission resources of different first transmission devices are non-overlapped, completely overlapped, or partially overlapped.

[0762] Suppose that the second transmission device configures one first transmission device with 1 group of common first transmission resources and common second transmission resources, 1 group of group first transmission resources and group second transmission resources, and 2 groups of dedicated first transmission resources and dedicated second transmission resources, the first transmission 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 DCI and / or downlink data in the corresponding second transmission resources.

[0763] By dividing a group of transmission resources into different types of transmission resources, in the case where the second transmission device configures at least one of the common transmission resources, the group transmission resources, and the dedicated transmission resources, the range of detection of the first transmission device is reduced, and the detection efficiency is improved.

[0764] 3.7 Determine information based on protocol pre-defined information or network configuration information:

[0771] In a possible design of the embodiment, the second transmission resource is used to transmit downlink data, and the downlink data is carried by the PDSCH.

[0772] Since the transmission resource indication information and the transmission parameter indication information are not included in the first indication information, the transmission parameters corresponding to the downlink data are determined based on protocol predefinition information or network configuration 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.

[0777] In a possible design of the embodiment, the second transmission resource is used only for transmitting a small data packet, or the second transmission resource is used only for SDT.

[0778] (3) The third transmission resource is used for transmitting the first uplink data.

[0787] Specific implementation details are not described here again with reference to 1.10 of the embodiment of FIG. 2.

[0788] This embodiment is exemplified by one acquisition module 1610, one transceiver module 1620, and one determination module 1630, and the number of the acquisition module 1610, the transceiver module 1620, and the determination module 1630 is not limited.

[0791] The transceiver module 1710 is configured to send first indication information on a first transmission resource in a set of transmission resources.

[0792] The transceiver module 1710 is configured to perform at least one of downlink transmission and uplink transmission on other transmission resources in the set of transmission resources based on the first indication information.

[0829] (3) The correspondence between the second transmission resource and the third transmission resource is one-to-one or many-to-one; wherein one-to-one means that one second transmission resource corresponds to one third transmission resource, and many-to-one means that multiple second transmission resources correspond to the same third transmission resource.

[0830] In a possible design of the embodiment, the location of the second transmission resource is determined based on the location of the first transmission resource; or, there is a predefined relationship between the location of the second transmission resource and the location of the first transmission resource based on a communication protocol; or, there is a preconfigured relationship between the location of the second transmission resource and the location of the first transmission resource based on a network.

[0831] In a possible design of the embodiment, the location of the third transmission resource is determined based on the location of the first transmission resource; or, there is a predefined relationship between the location of the third transmission resource and the location of the first transmission resource based on a communication protocol; or, there is a preconfigured relationship between the location of the third transmission resource and the location of the first transmission resource based on a network.

[0839] The time domain of the third transmission resource is adjacent to the time domain of the second transmission resource, which means that the end position of the time domain of the second transmission resource is adjacent to the start position of the time domain of the third transmission resource.

For example, when the third transmission resource is used to carry the HARQ feedback of the downlink data on the second transmission resource, the start position of the time domain of the third transmission resource is slightly later than the start position of the time domain of the second transmission resource, because the first transmission device needs to be reserved for processing time.

[0847] In a possible design of the embodiment, the first indication information is also used to indicate whether there is transmission on other transmission resources; in the case that the first indication information indicates that there is transmission on the other transmission resources, the first indication information is used to indicate the transmission content on the other transmission resources.

[0848] In a possible design of the embodiment, the first indication information is used for indicating whether there is transmission on the second transmission resource and / or the third transmission resource; in the case where the first indication information indicates that there is transmission on the second transmission resource, the first indication information is used for indicating the transmission content on the second transmission resource; in the case where the first indication information indicates that there is transmission on the third transmission resource, the first indication information is used for indicating the transmission content on the third transmission resource.

[0849] In a possible design of the embodiment, the first indication information is used for indicating the transmission content on the other transmission resource. If the first indication information indicates the transmission content on the second transmission resource, it can be determined that there is transmission on the second transmission resource; if the first indication information indicates the transmission content on the third transmission resource, it can be determined that there is transmission on the third transmission resource.

[0850] By indicating whether there is transmission on the other transmission resource through the first indication information, in the case where it is indicated that there is no transmission on the second transmission resource, the first transmission apparatus does not need to detect on the second transmission resource; in the case where it is indicated that there is no transmission on the third transmission resource, the first transmission apparatus does not need to transmit on the third transmission resource, thereby reducing the energy consumption of the first transmission apparatus.

[0851] FIG. 5 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 for indicating at least one of the following:

[0852] 4.3.1. Mode 1: Indicating no transmission on the second transmission resource.

[0853] In the case where the first indication information indicates no transmission on the second transmission resource, the second transmission apparatus does not transmit the DCI or the first downlink data, and the first transmission apparatus does not need to detect on the second transmission resource.

[0854] Optionally, the first transmission apparatus determines a first value or a first state or a first sequence based on the first indication information, and determines no transmission on the second transmission resource based on the first value or the first state or the first sequence.

[0855] The first value is a bit value or a group of bit values, for example, the first value is 1 or 0; the first state is an on state or an off state, which can be represented by a high or low level or a high or low energy, or can be represented by a bit value; the first sequence is a sequence used for representing 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.

[0856] 4.3.2 Way 2: Indicate the second transmission resource to transmit DCI or PDCCH.

[0857] In a possible design of the embodiment, the DCI or PDCCH is transmitted on the second transmission resource.

[0858] The second transmission device transmits the DCI or PDCCH on the second transmission resource, so that the first transmission device only needs to detect the PDCCH on the second transmission resource, for example, a search space is configured on the second transmission resource, and the first transmission device detects the DCI or PDCCH on the search space. In a possible design of the embodiment, the detection complexity of the search space is low, for example, 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 first transmission device only needs to perform PDCCH detection at most 2 times in the search space.

[0859] In the case that the first indication information indicates that the DCI or PDCCH is transmitted on the second transmission resource, the first transmission device only needs to detect the PDCCH on the second transmission resource, and does not need to continuously detect the PDCCH on all second transmission resources, which reduces the complexity of blind detection and achieves the effect of energy saving and consumption reduction.

[0860] Optionally, the DCI is carried on the PDCCH or the PDSCH. FIG. 6 shows a schematic diagram of a DCI transmission manner provided by an example embodiment of the present application.

[0868] Optionally, the first transmission device determines a third value or a third state or a third sequence based on the first indication information, and determines to transmit the first downlink data on the second transmission resource based on the third value or the third state or the third sequence.

[0869] Since the first indication information does not carry resource scheduling information, a transmission parameter corresponding to the first downlink data is determined based on protocol predefined information or network configuration information.

[0885] Feedback mode 2: the feedback information includes n information fields (n bits), respectively corresponding to the first downlink data on the n second transmission resources.

[0886] If the first transmission device detects the first downlink data on the i-th second transmission resource (detection success or detection failure), the first transmission device feeds back ACK or NACK on the i-th bit; if the first transmission device does not detect the first downlink data on the i-th second transmission resource, the first transmission device does not feed back (for example, fills in a specified character NULL) or feeds back NACK or ACK on the i-th bit.

[0887] In a possible design of the embodiment, if the first downlink data includes one transport block or codeword, the feedback information corresponds to 1 bit; if the first downlink data includes m transport blocks or codewords (m is greater than or equal to 2), the feedback information corresponds to m bits, or the feedback information corresponds to 1 bit, that is, m transport blocks or codewords correspond to all feedback information, and the feedback information is obtained by performing a bit-wise AND operation or a bit-wise OR operation on the feedback information.
