[0065] Next, the related technologies involved in the embodiments of the application are introduced:

[0066] · Physical Downlink Control CHannel (PDCCH) detection:

[0067] 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;

[0068] Table 1

[0069] · Terminal device complexity optimization:

[0070] 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.

[0071] 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.

[0072] 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 in measurement to adapt to the relevant 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.

[0073] In the related art, the terminal device can only detect the PDCCH in the search space configured by the network device, and the terminal device judges whether to receive the downlink data or transmit the 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 configuration method, and FIG. 2 shows a flowchart of the configuration method provided by an exemplary embodiment of the present application. The method is executed by the terminal device, and the method comprises the following steps:

[0074] Step 210: Obtain first configuration information.

[0075] The first configuration information is used to configure at least one group of transmission resources, and one group of transmission resources includes a first transmission resource and other transmission resources. The first transmission resource is used to transmit first indication information, the first indication information is used to indicate the transmission content on the other transmission resources, the other transmission resources are at least one transmission resource in the group of transmission resources except the first transmission resource, and there is a corresponding relationship between at least two transmission resources in the group of transmission resources.

[0076] In some embodiments, the first configuration information is obtained based on 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 configuration manner.

[0077] By carrying the first configuration information in the SIB or 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, speeding up the process of accessing the network. In addition, the terminal device can be configured during the system information update process, providing more flexible management and adjustment of the terminal device.

[0078] In some embodiments, the first configuration information is predefined by a communication protocol or sent by the network device.

[0079] 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 to transmit DCI and / or downlink data, and the third transmission resource is used to transmit feedback information and / or uplink data.

[0080] In some embodiments, the network device configures the terminal device with the first transmission resource and the second transmission resource through the first configuration information; or the network device configures the terminal device with the first transmission resource and the third transmission resource; or the network device 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 the other transmission resources as an example, which include one second transmission resource and one third transmission resource.

[0081] 1.1 Corresponding relationship and positional relationship between transmission resources:

[0082] 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:

[0083] (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;

[0084] (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;

[0085] (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.

[0086] FIG. 3 shows a schematic diagram of the corresponding relationship between the transmission resources according to an example embodiment of the present application.

[0087] The first transmission resource carries the first indication information, 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.

[0088] 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.

[0089] 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.

[0092] 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.

[0226] In some embodiments, the third transmission resource is used to transmit uplink data, and in the case where the TBS to be transmitted is smaller than the TBS that can be transmitted by the third transmission resource, the uplink data is transmitted multiple times (for example, first transmission and retransmission, or transmission of different redundancy versions) using the third transmission resource, and the transmission times of the multiple transmissions are determined based on the transmission times in the first configuration information.

[0227] By configuring the uplink data related parameter information, the data transmission efficiency can be improved, the possibility of data transmission failure can be reduced, and the reliability of data transmission can be enhanced.

[0228] 1.2.13 Correspondence between the first indication information and the transmission content:

[0229] In some embodiments, the first indication information is used to indicate a first value, and the first value is associated with the transmission content.

[0230] Optionally, a correspondence between the first value and the transmission content is determined by protocol predefined information or network configuration information.

[0231] For example, the first indication information is used to indicate 3 values of the first value, and a correspondence between the first value and the transmission content is shown in Table 2:

[0232] Table 2

[0233] 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, and in actual implementation, it can be expressed in binary, which is not limited in the embodiment.

[0234] For another example, the first indication information is used to indicate 6 values of the first value, and a 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.

[0235] Table 3

[0236] In the table, no transmission (or not involved) on the second transmission resource includes a case where the second transmission resource is not configured, and a case where the second transmission resource is configured but no transmission is performed on the second transmission resource; no transmission (or not involved) on the third transmission resource includes a case where the third transmission resource is not configured, and a case where the third transmission resource is configured but no transmission is performed on the third transmission resource.

[0237] 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"; and 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". The first value is expressed in decimal, and in actual implementation, binary expression can be used, which is not limited in the embodiment.

[0238] 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.

[0239] Optionally, the correspondence between the sequence index and the transmission content is determined by protocol predefined information or network configuration information.

[0240] For example, the first indication information is carried by 3 sequences, and the correspondence between the sequence index and the transmission content is shown in Table 4.

[0241] Table 4

[0242] 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"; and when the sequence index is 2, the corresponding transmission content is "transmission of first downlink data on the second transmission resource".

[0243] For another example, the first indication information is carried by 6 sequences, and the correspondence between the sequence index and the transmission content is shown in Table 5.

[0244] Table 5

[0245] In the table, no transmission (or not involved) on the second transmission resource includes a case where the second transmission resource is not configured, and a case where the second transmission resource is configured but no transmission is performed on the second transmission resource; no transmission (or not involved) on the third transmission resource includes a case where the third transmission resource is not configured, and a case where the third transmission resource is configured but no transmission is performed on the third transmission resource.

[0246] 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 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 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 first downlink data on the second transmission resource, 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, transmission of first uplink data on the third transmission resource".

[0247] 1.3 The first indication information:

[0248] In some embodiments, the first indication information is indicated in the form of a sequence, or is understood to be carried by a sequence, and the sequence type used to carry the first indication information includes at least one of a complex (vector) sequence and a real sequence.

[0249] The complex (vector) sequence includes at least one of a constant amplitude zero auto-correlation (CAZAC) sequence, a ZC (Zaddoff Chu) sequence, and the real sequence includes at least one of a pseudo-random sequence, a Gold sequence, an m-sequence, and a Hadamard sequence.

[0250] In some embodiments, the first indication information is carried by a first sequence, and the length of the first sequence is determined based on at least one of the following: protocol pre-defined information, network-sent configuration information, and the size of the frequency domain resource included in the first transmission resource.

[0251] For example, the first transmission resource includes K subcarriers or resource elements (REs), and the sequence length L is the largest prime number less than or equal to K, or is the largest prime number less than or equal to (K / A), where A is a predetermined positive integer, for example, A = 2 or 4.

[0252] For example, the sequence length L is the largest prime number less than or equal to K, K = 60, L = 59; or K = 72, L = 71; or K = 120, L = 113.

[0253] In some embodiments, the first indication information is carried by a first information associated with the first sequence, and the first information is determined based on at least one of the following: 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.

[0254] 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.

[0255] 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.

[0256] 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.

[0257] 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.

[0258] In some embodiments, the transmission contents on the other transmission resources are determined based on different first information associated with the first indication information. It can be understood that the transmission contents on the other transmission resources are indicated based on different first information associated with the first indication information.

[0259] 1.3.1 Optionally, the following five different indication manners can be used to indicate the transmission contents on the other transmission resources.

[0260] Indication manner one: the transmission contents on the other transmission resources are indicated based on a length corresponding to the first sequence;

[0261] Indication manner two: the transmission contents on the other transmission resources are indicated based on frequency domain resource corresponding to the first sequence;

[0262] Indication manner three: the transmission contents on the other transmission resources are indicated based on time domain resource corresponding to the first sequence;

[0263] Indication manner four: the transmission contents on the other transmission resources are indicated based on a sequence index corresponding to the first sequence;

[0264] Indication manner five: the transmission contents on the other transmission resources are indicated based on a sequence group index corresponding to the first sequence.

[0265] In some embodiments, the other transmission resource comprises at least one of a second transmission resource and a third transmission resource, and the transmission content on the other transmission resource comprises at least one of:

[0266] 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; and transmission of feedback information and first uplink data on the third transmission resource.

[0267] 1.3.1.1 For indication mode one: the transmission content on the other transmission resource is indicated based on the length corresponding to the first sequence.

[0268] The association relationship or corresponding relationship between the sequence length and the transmission content is determined based on protocol pre-defined information or network configuration information.

[0269] For example, one transmission content on the other transmission resource is indicated based on the length corresponding to the first sequence, 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, and the like, which are not limited in the present application.

[0270] For another example, multiple (two or more) transmission contents on the other transmission resource are indicated based on the length corresponding to the first sequence, 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, and the like, which are not limited in the present application.

[0271] 1.3.1.2 For indication mode two: the transmission content on the other transmission resource is indicated based on the frequency domain resource corresponding to the first sequence.

[0272] The association relationship or corresponding relationship between the frequency domain resource corresponding to the sequence and the transmission content is determined based on protocol pre-defined information or network configuration information.

[0273] 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.

[0274] For example, based on the time domain resource corresponding to the first sequence, one transmission content on other transmission resources is indicated, time domain resource index value 1 indicates no transmission on the second transmission resource, time domain resource index value 2 indicates transmission of DCI or PDCCH on the second transmission resource, and time domain resource index value 3 indicates transmission of the first downlink data on the second transmission resource, and the present application does not limit this.

[0275] For example, based on the time domain resource corresponding to the first sequence, multiple (two or more) transmission contents on other transmission resources are indicated, time domain resource index value 9 indicates no transmission on the second transmission resource and no transmission on the third transmission resource; time 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, and the present application does not limit this.

[0276] 1.3.1.3 For indication mode three: based on the time domain resource corresponding to the first sequence, the transmission content on other transmission resources is indicated.

[0277] There is an association 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.

[0278] 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.

[0279] For example, based on the time domain resource corresponding to the first sequence, one transmission content on other transmission resources is indicated, time domain resource index value 1 indicates no transmission on the second transmission resource, time domain resource index value 2 indicates transmission of DCI or PDCCH on the second transmission resource, and time domain resource index value 3 indicates transmission of the first downlink data on the second transmission resource, and the present application does not limit this.

[0280] For example, based on the time domain resource corresponding to the first sequence, multiple (two or more) transmission contents on other transmission resources are indicated, time domain resource index value 9 indicates no transmission on the second transmission resource and no transmission on the third transmission resource; time 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, and the present application does not limit this.

[0281] 1.3.1.4 For indication mode four: based on the sequence index corresponding to the first sequence, the transmission content on other transmission resources is indicated.

[0282] There is an association or correspondence between the sequence index corresponding to the sequence and the transmission content, which is determined based on protocol pre-defined information or network configuration information.

[0283] For example, based on the sequence index corresponding to the first sequence, one transmission content on the other transmission resource is indicated, sequence index 1 indicates no transmission on the second transmission resource, sequence index 2 indicates transmission of DCI or PDCCH on the second transmission resource, sequence index 3 indicates transmission of the first downlink data on the second transmission resource, and the like, which are not limited in the present application.

[0284] For another example, based on the sequence index corresponding to the first sequence, multiple (two or more) transmission contents on the other transmission resource are indicated, sequence index 9 indicates no transmission on the second transmission resource, no transmission on the third transmission resource; sequence index 10 indicates transmission of the first downlink data on the second transmission resource, transmission of feedback information on the third transmission resource, and the like, which are not limited in the present application.

[0285] 1.3.1.5 For indication mode five: based on the sequence group index corresponding to the first sequence, the transmission content on the other transmission resource is indicated.

[0286] The sequence group index corresponding to the sequence and the transmission content have an association relationship or a corresponding relationship, which is determined based on the protocol predefined information or the network configuration information.

[0287] For example, based on the sequence group index corresponding to the first sequence, one transmission content on the other transmission resource is indicated, sequence group index 1 indicates no transmission on the second transmission resource, sequence group index 2 indicates transmission of DCI or PDCCH on the second transmission resource, sequence group index 3 indicates transmission of the first downlink data on the second transmission resource, and the like, which are not limited in the present application.

[0288] For another example, based on the sequence group index corresponding to the first sequence, multiple (two or more) transmission contents on the other transmission resource are indicated, sequence group index 9 indicates no transmission on the second transmission resource, no transmission on the third transmission resource; sequence group index 10 indicates transmission of the first downlink data on the second transmission resource, transmission of feedback information on the third transmission resource, and the like, which are not limited in the present application.

[0289] The first indication information is carried in the form of sequence, so that the terminal device can judge the content indicated by the first indication information based on sequence detection, and the transmission behavior on the subsequent other transmission resource can be determined based on sequence detection, without blind detection in a group of transmission resources, and decoding processing is avoided, reducing the power consumption and processing delay of the terminal device.

[0290] 1.3.2 FIG. 5 shows a schematic diagram of the indication mode of the first indication information provided by an example embodiment of the present application. The first indication information is used to indicate at least one of the following modes:

[0291] 1.3.2.1 Mode 1: Indicating no transmission on the second transmission resource.

[0292] 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.

[0293] Optionally, a first value or a first state or a first sequence is determined based on the first indication information, and no transmission on the second transmission resource is determined based on the first value or the first state or the first sequence.

[0294] The first value is a one-bit value or a group of bit values, such as a value of 1 or 0 for the first value; the first state is an on state (on) or an off state (off), 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 again.

[0295] 1.3.2.2 Mode 2: Indicating transmission of DCI or PDCCH on the second transmission resource.

[0296] In some embodiments, based on the first indication information, DCI or PDCCH is received on the second transmission resource.

[0297] In the case that the first indication information indicates transmission of DCI or PDCCH on the second transmission resource, the terminal device detects 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 DCI or PDCCH on the search space. In some embodiments, the detection complexity of the search space is low, such as that 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.

[0298] By indicating transmission of DCI or PDCCH on the second transmission resource in the case that the first indication information indicates transmission of DCI or PDCCH on the second transmission resource, it is only necessary to detect PDCCH on the second transmission resource, and it is not necessary to continuously detect PDCCH on all second transmission resources, thereby reducing the detection complexity and achieving the effect of energy saving and consumption reduction.

[0299] 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.

[0300] 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.

[0301] 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.

[0302] Optionally, the second value or the second state or the second sequence is determined based on the first indication information, and the DCI or the PDCCH is determined to be transmitted on the second transmission resource based on the second value or the second state or the second sequence.

[0303] In some embodiments, the DCI or the downlink control channel is received on the second transmission resource based on the first indication information, 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.

[0304] In some embodiments, the method further includes: transmitting, based on the first indication information, feedback information corresponding to the second downlink data on the third transmission resource.

[0305] As shown in FIG. 7, the second transmission resource, the third transmission resource, and the fourth transmission resource are different transmission resources, the DCI or the downlink control channel is received on the second transmission resource, and the second downlink data is not received on the second transmission resource, the second downlink data is received on the fourth transmission resource, and 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.

[0306] 1.3.2.3 Mode 3: Indicating that the first downlink data is transmitted on the second transmission resource.

[0307] 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.

[0308] 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.

[0309] Optionally, the first downlink data is carried by the PDSCH.

[0310] Optionally, the third value or the third state or the 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.

[0311] 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 some embodiments, the transmission parameter includes at least one of the following:

[0312] 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; 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; DeModulation Reference Signal (DMRS) information corresponding to the first downlink data;

[0313] 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 processing such as filling redundant bits.

[0314] 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.

[0315] 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 predefined information or network configuration information.

[0316] 1.3.2.4 Mode 4: Indicate that the first downlink data is transmitted on the second transmission resource, and the feedback information is transmitted on the third transmission resource.

[0317] 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.

[0318] 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.

[0319] The terminal device transmits feedback information, such as Hybrid Automatic Repeat reQuest (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.

[0320] 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.

[0321] In some embodiments, in a 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.

[0322] 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 feedback information corresponding to the first downlink data on the third transmission resource, such as HARQ feedback information ACK or NACK.

[0323] In some embodiments, the feedback information includes at least one of the following: HARQ information; Precoding Matrix Indicator (PMI) information; Rank Indicator (RI) information; Channel State Information (CSI); reference signal index information; and Link Recovery Request (LRR), and which feedback information is specifically fed back can be determined based on network configuration information or the first indication information.

[0324] Optionally, the feedback information is carried by a PUCCH, and a PUCCH format and / or a PUCCH resource are determined by network configuration information or the first indication information.

[0325] In some embodiments, 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.

[0326] The second transmission resource and the third transmission resource are in a one-to-many 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 by the n second transmission resources.

[0327] In some embodiments, the feedback mode includes at least one of the following:

[0328] Feedback mode 1: n feedback information bundling feedback: bit-wise operation or bit-or operation is performed on the feedback information corresponding to the first downlink data transmitted by the n second transmission resources, to obtain 1-bit information, and feedback is performed through the 1-bit information.

[0329] Feedback mode 2: The feedback information includes n information fields (n bits), which respectively correspond to the first downlink data on the n second transmission resources.

[0330] If the terminal device detects the first downlink data on the ith second transmission resource (detection success or detection failure), the terminal device feeds back ACK or NACK on the ith bit; if the terminal device does not detect the first downlink data on the ith 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 ith bit.

[0331] FIG. 8 shows a schematic diagram of a feedback mode provided by an example embodiment of the present application. The second transmission resource and the third transmission resource are in a one-to-many correspondence, and in FIG. 8, 4 second transmission resources correspond to 1 third transmission resource, and the feedback information corresponding to the downlink data on the 4 second transmission resources is all fed back through the same third transmission resource.

[0332] Suppose that the first second transmission resource transmits first downlink data 1, the terminal device detects successfully, and the feedback information is ACK; the fourth second transmission resource transmits first downlink data 2, the terminal device detects unsuccessfully, and the feedback information is NACK; and the second second transmission resource and the third second transmission resource are not transmitted.

[0333] If feedback mode 1 is used, multiple feedback information bundling (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.

[0334] If the feedback mode 2 is used, the feedback information of the third transmission resource corresponds to 4 bits, which respectively correspond to the feedback information of the downlink transmission on the 4 second transmission resources. The first downlink data 1 and the first downlink data 2 correspond to the first bit and the fourth bit of the 4 bits respectively. The second bit and the third bit of 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).

[0335] 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 (i.e., does not send ACK) on the third transmission resource.

[0336] 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 (i.e., does not send NACK) on the third transmission resource.

[0337] 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, i.e., the bitwise OR operation or the bitwise OR operation is performed on all the feedback information corresponding to the m transport blocks or codewords, and 1 bit of feedback information is obtained.

[0338] 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 bitwise OR operation or the bitwise OR operation of the feedback information corresponding to the first downlink data transmitted on the plurality of second transmission resources. The 1 bit is used to indicate positive acknowledgement or negative acknowledgement.

[0339] By way of example and 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.

[0340] 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.

[0341] FIG. 9 shows a schematic diagram of a feedback mode provided by an example embodiment of the present application.

[0342] 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, 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 bit OR operation.

[0343] 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, the code word 0, code word 1, code word 2, code word 3 is respectively transmitted on the 4 second transmission resources, the value of the feedback information on the third transmission resource is determined based on the bit 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.

[0344] FIG. 10 shows a schematic diagram of a feedback mode provided by an example embodiment of the present application.

[0345] In (a) 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 same code word 1 and code word 0 is transmitted on the 4 second transmission resources, the 1 bit value of the feedback information on the third transmission resource is determined based on the bit AND operation of the feedback information corresponding to the code word 1 and the feedback information corresponding to the code word 0, as long as the code word 1 is successfully detected on any one of the second transmission resources, and the code word 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 code word 1 on the first second transmission resource is successfully detected, and the code word 0 on the second second transmission resource is successfully detected, the feedback information on the third transmission resource is ACK. If the feedback information transmitted on the third transmission resource corresponds to 2 bits, the same code word 1 and code word 0 is transmitted on the 4 second transmission resources, the 2 bit value of the feedback information on the third transmission resource is respectively determined based on the feedback information corresponding to the code word 1 and the feedback information corresponding to the code word 0, as long as the code word 1 is successfully detected on any one of the second transmission resources, the first bit of the 2 bit feedback information is ACK, otherwise it is NACK; as long as the code word 0 is successfully detected on any one of the second transmission resources, the first bit of the 2 bit feedback information is ACK, otherwise the feedback information is NACK. Assuming that the code word 1 on the first second transmission resource is successfully detected, the first bit of the feedback information is determined to be ACK; the code word 0 is not successfully detected on the four second transmission resources, the second bit of the feedback information is determined to be NACK.

[0346] 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.

[0347] 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.

[0350] 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.

[0352] 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.

[0353] 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.

[0354] 1.3.2.6 Mode 6: Indicating the third transmission resource for transmitting the first uplink data.

[0360] 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.

[0361] 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:

[0381] 1.3.3 Type of a set of transmission resources:

[0382] In some embodiments, the set of transmission resources is a common transmission resource shared by a plurality of terminal devices, or the set of transmission resources is a group transmission resource shared by a group of terminal devices, or the set of transmission resources is a dedicated transmission resource used by a terminal device.

[0383] In some embodiments, when the set of transmission resources is a common transmission resource shared by a plurality of terminal devices or a group transmission resource shared by a group of terminal devices, the other transmission resources in the set of transmission resources include the second transmission resource, and the second transmission resource is used to transmit common DCI and / or common downlink data, and the common DCI and / or 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.

[0384] 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, and the third transmission resource is used for the terminal device to transmit a random access sequence.

[0385] 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 to the plurality of terminal devices; the network device configures the same sequence for the plurality of terminal devices, or respectively configures a corresponding sequence for each terminal device, and the terminal device detects the first indication information on the first transmission resource based on the configured sequence.

[0386] For example, the network device configures sequence 1 for terminal device 1 and configures sequence 1 for terminal device 2, and both terminal device 1 and terminal device 2 detect the first indication information on the first transmission resource based on sequence 1.

[0387] 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.

[0388] The network device 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 the common downlink data on the second transmission resource.

[0389] 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.

[0390] 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.

[0391] If the terminal device detects the first indication information, it detects the common DCI and / or the common downlink data on the second transmission resource based on the first indication information, and the common DCI and the common downlink data are used to transmit at least one of the following information: broadcast information, system information, paging information, random access response information;

[0392] The broadcast information is, for example, Master Information Block (MIB) information; the system information is, for example, System Information Block (SIB) information; the paging information is, for example, Paging information; and the random access response information is, for example, Random Access Response (RAR) information.

[0393] 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.

[0394] 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.

[0395] In some embodiments, the network device configures a group transmission resource common to a group of terminal devices, including a group first transmission resource and a group second transmission resource, the group second transmission resource being used for transmitting group common DCI and group common downlink data.

[0396] Optionally, the group of terminal devices includes all terminal devices within 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.

[0397] For example, the common DCI and the common downlink data are used for transmitting at least one of the following: slot format information, channel occupation time duration information, available resource block set information, search space set group switching information, pre-emption indication information, Transmission Power Control (TPC) information, UL transmission cancellation indication information, and Wake-up indication information.

[0398] 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.

[0399] 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.

[0400] 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.

[0401] For 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.

[0402] For example, if 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.

[0403] 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.

[0404] 1.3.4 Determine information based on protocol pre-defined information or network configuration information:

[0410] (2) The second transmission resource is used to transmit the first downlink data.

[0411] In some embodiments, the second transmission resource is used to transmit the downlink data, and the downlink data is carried by a PDSCH.

[0412] 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.

[0413] 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:

[0416] 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.

[0417] 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).

[0418] (3) The third transmission resource is used for transmission of the first uplink data.

[0419] 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:

Since the first transmission resource and the other transmission resources are a set of transmission resources that are associated, for each set of transmission resources, only the first indication information on the first transmission resource needs to be detected, and the transmission behavior on the subsequent other transmission resources can be determined based on the first indication information. In a set 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.

[0423] The method provided in this 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.

[0627] (2) The second transmission resource is used to transmit the first downlink data.

[0628] In some embodiments, the second transport resource is used to transmit downlink data, which is carried by the PDSCH.

[0629] Since the first indication information does not include transmission resource indication information and transmission parameter indication information, the transmission parameters corresponding to the downlink data are determined based on protocol predefined information or network configuration information.

[0637] In summary, the method provided in this embodiment configures at least one set of transmission resources by sending first configuration information. This set of transmission resources includes a first transmission resource and other transmission resources. The first transmission resource transmits first indication information, which in turn indicates the transmission content on other transmission resources. This enables the terminal device to perform transmission on subsequent transmission resources based on the first indication information. Since the first transmission resource and other transmission resources are a related set, for each set of transmission resources, only the first indication information on the first transmission resource needs to be detected to determine the transmission behavior on subsequent transmission resources. This eliminates the need for blind detection or reduces the complexity of blind detection within a set of transmission resources, achieving energy saving and consumption reduction.

[0638] The method provided in this embodiment also improves the resource utilization efficiency and data transmission efficiency of the second transmission resource by simultaneously transmitting DCI and first downlink data on the second transmission resource.

[0639] In the above embodiments, the embodiments corresponding to FIG2 and FIG14 can be implemented individually or in combination. In the embodiments corresponding to FIG2 and FIG14, methods 1 to 7 can be implemented individually or in combination, and this application does not limit this.

[0640] Figure 15 shows a block diagram of a first configuration device provided in an exemplary embodiment of this application. This device can be implemented as a terminal device, or as part of a terminal device, through software or hardware, or a combination of both. The device includes:

[0641] The acquisition module 1510 is used to acquire first configuration information. The first configuration information is used to configure at least one set of transmission resources. The at least one set of transmission resources includes: the first transmission resource and other transmission resources.

[0642] Wherein, the first transmission resource is used to transmit the first indication information, the first indication information is used to indicate the transmission content on other transmission resources, the other transmission resources are at least one transmission resource other than the first transmission resource in a set of transmission resources, and there is a corresponding relationship between at least two transmission resources in a set of transmission resources.

[0643] In one possible design of this embodiment, the acquisition module 1510 is used to acquire first configuration information based on SIB or RRC signaling. Optionally, the first configuration information configures at least one set of transmission resources in a semi-static configuration manner.

[0644] By carrying the first configuration information in the SIB or RRC signaling, no additional signaling is required, reducing signaling transmission overhead. Furthermore, the first configuration device can be quickly configured after it is connected to the network device, accelerating the network access process. In addition, the first configuration device can be configured during system information updates, allowing for more flexible management and adjustment of the first configuration device.

[0645] In one possible design of this embodiment, the first configuration information is predefined by the communication protocol or sent by the network device.

[0646] In one possible design of this embodiment, 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 to transmit DCI and / or downlink data, and the third transmission resource is used to transmit feedback information and / or uplink data.

[0647] In one possible design of this embodiment, the network device configures a first transmission resource and a second transmission resource to the first configuration device using the aforementioned first configuration information; or, the network device configures a first transmission resource and a third transmission resource to the first configuration device; or, the network device configures a first transmission resource, a second transmission resource, and a third transmission resource to the first configuration device. In a set of transmission resources, there may be multiple first, second, and third transmission resources. The following embodiments primarily illustrate this by using other transmission resources including one second transmission resource and one third transmission resource.

[0648] 3.1 Correspondence and positional relationships between transmission resources:

[0649] In one possible design of this embodiment, the correspondence relationship can also be called an association relationship, and the correspondence relationship includes at least one of the following:

[0650] (1) The correspondence between the first transmission resource and the second transmission resource is one-to-one or many-to-one; where 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.

[0651] (2) The correspondence between the first transmission resource and the third transmission resource is one-to-one or many-to-one; where 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.

[0652] (3) The correspondence between the second transmission resource and the third transmission resource is one-to-one or many-to-one; where 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.

[0653] When the correspondence between transmission resources is one-to-one, the first configuration device can continue to provide real-time feedback for each received downlink data, resulting in low feedback latency. When the correspondence between transmission resources is many-to-one, for multiple received downlink data, the first configuration device provides feedback for one uplink data, reducing the system overhead of uplink transmission.

[0654] In one possible design of this 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 the communication protocol; or, there is a pre-configured relationship between the location of the second transmission resource and the location of the first transmission resource based on the network.

[0655] In one possible design of this 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 the communication protocol; or, there is a pre-configured relationship between the location of the third transmission resource and the location of the first transmission resource based on the network.

[0656] In one possible design of this embodiment, 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 the communication protocol; or, there is a pre-configured relationship between the location of the third transmission resource and the location of the second transmission resource based on the network.

[0657] In one possible design of this embodiment, 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 the communication protocol; or, there is a pre-configured relationship between the location of the third transmission resource and the location of the second transmission resource based on the network.

[0658] In one possible design of this embodiment, the time-domain start position of the first transmission resource is no later than the time-domain start position of the second transmission resource, and the time-domain start position of the second transmission resource is no later than the time-domain start position of the third transmission resource. For example, when using the third transmission resource to carry HARQ feedback of downlink data on the second transmission resource, since processing time needs to be reserved for the first configuration device, the time-domain start position of the third transmission resource is slightly later than the time-domain start position of the second transmission resource.

[0659] For specific real-time details, please refer to section 1.1 of the embodiment shown in Figure 2, which will not be repeated here.

[0660] In one possible design of this embodiment, the transmitted content includes at least one of the following:

Feedback information includes acknowledgment (ACK) or denial (NACK) feedback corresponding to the first downlink data transmitted on the second transmission resource or the downlink shared channel or downlink data channel, and / or ACK or NACK corresponding to the second downlink data transmitted on the fourth transmission resource or the downlink shared channel or downlink data channel. The fourth transmission resource is the downlink transmission resource scheduled by the DCI or downlink control channel carried on the second transmission resource.

[0663] In one possible design of this embodiment, the feedback information includes at least one of the following: acknowledgment feedback or denial feedback; RSRQ obtained based on the measurement reference signal; RSRP; CSI; PMI; RI; reference signal index information; LRR.

[0664] In one possible design of this embodiment, the first indication information is also used to indicate whether there is transmission on other transmission resources; when the first indication information indicates that there is transmission on other transmission resources, the first indication information is used to indicate the transmission content on other transmission resources.

If the first indication information indicates the transmission content on a second transmission resource, it can be implicitly determined that there is transmission on the second transmission resource; if the first indication information indicates the transmission content on a third transmission resource, it can be implicitly determined that there is transmission on the third transmission resource.

[0667] The first configuration device indicates whether there is transmission on other transmission resources by indicating that there is no transmission on the second transmission resource. If the first configuration device indicates that there is no transmission on the second transmission resource, the first configuration device does not need to detect on the second transmission resource. If the first configuration device indicates that there is no transmission on the third transmission resource, the first configuration device does not need to send on the third transmission resource, thereby reducing the energy consumption of the first configuration device.
