[0092] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0096] Figure 1 FIG. 1 is a schematic flowchart of a method for sending configuration information according to an embodiment of the present disclosure. The method for sending configuration information shown in this embodiment may be executed by a base station, and the base station includes, but is not limited to, a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station. The base station may communicate with a terminal serving as a user equipment, and the terminal includes, but is not limited to, communication devices such as a mobile phone, a tablet computer, a wearable device, a sensor, and an Internet of Things device.

[0097] In one embodiment, a plurality of transmission and reception points TRP for receiving a configured grant physical uplink shared channel CG PUSCH may be provided in the base station.

[0098] As Figure 1 shown, the method for sending configuration information may include the following steps:

[0099] In step S101, configuration information is sent to the terminal, where the configuration information is used to determine the RV value at each transmission opportunity when the terminal repeatedly sends the same transport block in the directions facing different TRPs, and the transmission opportunity belongs to one or more CG PUSCH configurations.

[0100] In one embodiment, the terminal may perform uplink transmission in the directions facing different TRPs. For example, the PUSCH is sent in the directions facing different TRPs. The terminal may use different beams in the directions facing different TRPs, and the base station may configure transmission resources for the uplink transmission performed by the terminal in the direction facing each TRP.

[0101] Taking the terminal transmitting PUSCH as an example, in order to enhance uplink transmission, the base station may configure the terminal to repeatedly transmit the same transport block (TB). The repeated transmission method may be CG, and for the directions of the terminal facing different TRPs (for example, the uplink beams respectively used by the terminal in the directions facing different TRPs), CG PUSCH configurations may be configured. Specifically, one CG PUSCH configuration may be configured, or multiple CG PUSCH configurations may be configured.

[0102] Multiple transmission occasions (TO, also referred to as transmission opportunities) can be included in the CG PUSCH configuration, and the terminal can use these multiple transmission occasions to repeatedly transmit the same transport block. The transmission occasions configured for CG PUSCH can be configured for the uplink transmission in the direction of each TRP faced by the terminal. The specific relationship between the CG PUSCH configuration and the uplink transmission in the direction of different TRPs faced by the terminal will be described in the subsequent embodiments.

[0103] In order for the terminal to repeatedly send the same transport block using the transmission occasions configured for CG PUSCH in the direction of different TRPs, it first needs to determine the redundancy version (RV) value used in each of the transmission occasions, so as to perform rate matching based on the RV value in the corresponding transmission occasion, and then send the transport block.

[0104] In one embodiment, the base station can configure information for the terminal; on the one hand, the configuration information can be used by the terminal to determine the RV values in each of the transmission occasions when repeatedly sending the same transport block in the direction of different TRPs, so that the terminal can perform rate matching according to the corresponding RV values at each of the transmission occasions. On the other hand, the configuration information can be used by the base station to determine the RV values in each of the transmission occasions when the terminal repeatedly sends the same transport block in the direction of different TRPs, so that when the base station receives the transport block sent by the terminal, it can perform rate matching using the corresponding RV for receiving and decoding.

[0105] In one embodiment, the way for the terminal to repeatedly send the same transport block can adopt the PUSCH repetition type A transmission mode or the PUSCH repetition type B transmission mode, and can be specifically selected according to needs, which is not limited in this disclosure.

[0106] Among them, the PUSCH repetition type A transmission mode means that a PUSCH is transmitted in K consecutive time slots, there is one transmission occasion in each time slot, a total of K transmission occasions, starts to transmit on the Sth symbol in the starting time slot, each transmission occasion lasts for L symbols, and at the same time S + L does not exceed the time slot boundary.

[0107] In this case, since the transmission occasion does not exceed the time slot boundary, without conflict, each transmission occasion is the same as the transmission occasion configured for CG PUSCH by the base station, and this transmission occasion can be called the nominal transmission occasion.

[0108] The PUSCH repetition type B transmission mode means that a PUSCH starts transmission on the S-th symbol in the starting time slot, continuously sends K transmission opportunities, each transmission opportunity continuously (back-to-back) occupies L symbols, and S + L can cross the time slot boundary. In the case where the transmission opportunity crosses the time slot boundary, the transmission is re-segmented. For the entire transmission, the time slot L40K represents the time window length of the PUSCH transmission, and the downlink symbols (time domain symbols) and other invalid symbols are discarded and not used for the PUSCH transmission.

[0109] In this case, since the transmission opportunity may exceed the opportunity boundary and thus be re-segmented, this results in a difference between the actual transmission opportunity used by the terminal and the transmission opportunity configured by the base station for the CG PUSCH. This transmission opportunity can be called the actual transmission opportunity.

[0110] In addition, for the downlink symbols and other invalid symbols being discarded and not used for the PUSCH transmission, which also leads to a difference between the actual transmission opportunity used by the terminal and the transmission opportunity configured by the base station for the CG PUSCH, this transmission opportunity is also called the actual transmission opportunity.

[0111] In one embodiment, the type of the CG PUSCH configuration configured by the base station for the terminal can be CG type 1 or CG type 2, and specific selection can be made according to needs, which is not limited in this disclosure.

[0112] Among them, for the configuration of CG type 1, the Radio Resource Control (RRC) layer provides the uplink grant, including the activation of the grant; it takes effect immediately when the RRC configuration is correctly received. All transmission parameters are configured through RRC signaling, including the period, time offset, and frequency resources, as well as the modulation and coding scheme used for the uplink transmission. When the RRC configuration is received, the terminal starts to transmit using the CG configuration at the moment given by the period and offset. The offset can be used to control at which moment the terminal is allowed to transmit.

[0113] For the configuration of CG type 2, the RRC layer provides the transmission period. The base station realizes the resource activation and the configuration of some transmission parameters through Downlink Control Information (DCI), so as to realize the activation transmission of this authorized configuration. After receiving the activation command, if there is data to send in the buffer, the terminal will transmit according to the pre-configured period; if there is no data, the terminal will not transmit any data. The transmission time of the Physical Downlink Control Channel (PDCCH) specifies the activation time. The terminal confirms the activation / deactivation of the CG type 2 configuration by sending the uplink Media Access Control (MAC) control signaling.

[0114] In one embodiment, the method further includes: receiving the same transport block repeatedly sent by the terminal at each of the transmission opportunities in the directions facing different TRPs.

[0115] The base station can receive the same transport block repeatedly sent by the terminal at each of the transmission opportunities in the directions facing different TRPs. For the transport block sent at each of the transmission opportunities, the RV value corresponding to the transmission opportunity can be used for rate matching during reception for receiving and decoding.

[0116] In one embodiment, the method further includes: sending a CG PUSCH configuration to the terminal; wherein, the transmission opportunities used by the terminal to repeatedly send the same transport block in the directions facing different TRPs belong to the same CG PUSCH configuration.

[0117] The base station can send only one CG PUSCH configuration to the terminal for the terminal to use when repeatedly sending the same transport block in the directions facing different TRPs. In this case, the transmission opportunities of this one CG PUSCH configuration need to be allocated for the terminal to repeatedly send the same transport block in the directions facing different TRPs.

[0118] For example, the transmission opportunities of this one CG PUSCH configuration can be evenly allocated for the terminal to repeatedly send the same transport block in the directions facing each TRP. Taking the directions of 2 TRPs as an example, for instance, if there are 8 transmission opportunities for the CG PUSCH configuration, the terminal can use 4 of them when repeatedly sending the same transport block in the direction of TRP1 and use the other 4 when repeatedly sending the same transport block in the direction of TRP2.

[0119] For example, the transmission opportunity configured for this CG PUSCH can be multiplexed and allocated to the terminal to repeatedly transmit the same transport block in the direction facing each of the said TRPs. Taking the directions of 2 TRPs as an example, for instance, if there are 8 transmission opportunities configured for the CG PUSCH, the terminal can use these 8 transmission opportunities when repeatedly transmitting the same transport block in the direction towards TRP1, and also use these 8 transmission opportunities when repeatedly transmitting the same transport block in the direction towards TRP2. When the terminal performs uplink transmission in different TRP directions, different antennas can be used, or the same antenna can be used.

[0120] In one embodiment, when the base station sends a configuration for a CG PUSCH to the terminal, the configuration information belongs to this CG PUSCH configuration. Then the configuration information can include multiple RV sequences, or include one RV sequence, or include one RV sequence and an offset parameter.

[0121] The RV sequences include but are not limited to the following three: {0, 2, 3, 1}, {0, 0, 0, 0}, {0, 3, 0, 3}. In the case where the configuration information includes multiple RV sequences, it can be including multiple of the same kind of RV sequences, or including multiple different kinds of RV sequences. The following embodiments mainly describe the case of including multiple different kinds of RV sequences.

[0122] Figure 2 It is a schematic flowchart of another method for sending configuration information shown according to an embodiment of the present disclosure. As Figure 2 shown, the configuration information includes multiple RV sequences, and the method further includes:

[0123] In step S201, according to the direction of the TRP and the beam mapping rule, group the transmission opportunities configured for the CG PUSCH to determine a transmission opportunity group corresponding to each direction of the said TRP;

[0124] In step S202, determine the RV sequence corresponding to each of the said transmission opportunity groups;

[0125] In step S203, cyclically map the RV values in the RV sequence to each transmission opportunity in the corresponding transmission opportunity group.

[0126] In one embodiment, when the configuration information includes multiple RV sequences, it is necessary to map multiple RV sequences to the transmission opportunities of the CG PUSCH configuration used for the terminal to perform uplink transmission in the direction facing each TRP. In this case, since there is only one CG PUSCH configuration, it is necessary to group the transmission opportunities of the CG PUSCH configuration.

[0127] The transmission opportunities configured for the CG PUSCH can be grouped according to the direction of the TRP and the beam mapping rule, so as to determine a transmission opportunity group corresponding to the direction of each TRP.

[0128] Among them, when the terminal performs uplink transmission in the directions of different TRPs, different beams can be used. For example, when facing the direction of TRP1, beam 1 can be used for uplink transmission, and when facing the direction of TRP2, beam 2 can be used for uplink transmission. The beam mapping rule refers to the mapping relationship between the transmission opportunities configured for the CG PUSCH and the beams used for the terminal to perform uplink transmission in the directions of different TRPs.

[0129] The beam mapping rule includes but is not limited to the following three types: periodic mapping, continuous mapping, and half-and-half mapping. Still taking the 8 transmission opportunities in the CGPUSCH configuration and the directions of two TRPs as an example, the beams used for the directions of the two TRPs are: beam 1 is used for the direction of TRP1, and beam 2 is used for the direction of TRP2.

[0130] For example, in the case of periodic mapping, the 8 transmission opportunities can be mapped to beam 1 and beam 2 in sequence. For example, the 1st, 3rd, 5th, and 7th transmission opportunities are mapped to beam 1, and the 2nd, 4th, 5th, and 6th transmission opportunities are mapped to beam 2.

[0131] For example, in the case of continuous mapping, for the mapping pattern of two beams being beam 1, beam 1, beam 2, beam 2, then the 8 transmission opportunities can be mapped to beam 1 and beam 2 according to this pattern, that is, the 1st, 2nd, 5th, and 5th transmission opportunities are mapped to beam 1, and the 2nd, 3rd, 7th, and 8th transmission opportunities are mapped to beam 2.

[0132] For example, in the case of half-and-half mapping, half of the 8 transmission opportunities can be mapped to beam 1, and the other half of the transmission opportunities can be mapped to beam 2, that is, the 1st, 2nd, 3rd, and 4th transmission opportunities are mapped to beam 1, and the 5th, 6th, 7th, and 8th transmission opportunities are mapped to beam 2.

[0133] Regarding the specific beam mapping rule, it can be selected according to needs, and the present disclosure does not make any restrictions. For the convenience of examples below, the description is mainly focused on the case of periodic mapping.

[0134] For periodic mapping, a transmission opportunity group can be determined respectively for the uplink transmission in the directions of multiple TRPs. As described above, for the directions of two TRPs, the 8 transmission opportunities in the CG PUSCH configuration can be divided into two transmission opportunity groups. Among them, group 1 corresponds to the direction of TRP1 and includes the 1st, 3rd, 5th, and 7th transmission opportunities, and group 2 corresponds to the direction of TRP2 and includes the 2nd, 4th, 5th, and 6th transmission opportunities.

[0135] The number of multiple RV sequences included in the configuration information may correspond to the number of transmission opportunity groups. For example, for 2 transmission opportunity groups, 2 RV sequences may be configured. For example, RV sequence 1 corresponds to transmission opportunity group 1, and RV sequence 2 corresponds to transmission opportunity group 2.

[0136] For example, if RV sequence 1 is {0, 2, 3, 1} and RV sequence 2 is {0, 3, 0, 3}, then the RV values in the RV sequence {0, 2, 3, 1} can be cyclically mapped to the 1st, 3rd, 5th, and 7th transmission opportunities. That is, the RV value of the 1st transmission opportunity is 0, the RV value of the 3rd transmission opportunity is 2, the RV value of the 5th transmission opportunity is 3, and the RV value of the 6th transmission opportunity is 1; similarly, the RV values in the RV sequence {0, 3, 0, 3} can be cyclically mapped to the 2nd, 4th, 6th, and 8th transmission opportunities. That is, the RV value of the 2nd transmission opportunity is 0, the RV value of the 4th transmission opportunity is 3, the RV value of the 6th transmission opportunity is 0, and the RV value of the 8th transmission opportunity is 3.

[0137] Figure 3 It is a schematic flowchart of another method for sending configuration information shown according to an embodiment of the present disclosure. As Figure 3 shown, the configuration information includes an RV sequence and an offset parameter, and the method further includes:

[0138] In step S301, multiple RV sequences including the RV sequence are determined according to the RV sequence and the offset parameter;

[0139] In step S302, according to the direction of the TRP and the beam mapping rule, the transmission opportunities configured for the CG PUSCH are grouped to determine the transmission opportunity groups respectively corresponding to the directions of each TRP;

[0140] In step S303, the RV sequences respectively corresponding to each transmission opportunity group are determined;

[0141] In step S304, the RV values in the RV sequence are cyclically mapped to the transmission opportunities in the corresponding transmission opportunity group.

[0142] In one embodiment, in the case where the configuration information includes an RV sequence and an offset parameter, multiple RV sequences including the RV sequence can be determined according to the RV sequence and the offset parameter. For example, new RV sequences can be determined according to the RV sequence and the offset parameter, and the original RV sequence and the new RV sequences constitute multiple RV sequences.

[0143] For example, taking the RV sequence {0, 2, 3, 1} as an example, there is an offset parameter 2. Then, the values in the RV sequence can be collectively shifted left by 2 bits to obtain a new RV sequence {3, 1, 0, 2}; or in base-4, 2 can be added to each RV value to obtain a new RV sequence {2, 0, 1, 3}. The way to obtain a new RV sequence based on the RV sequence and the offset parameter can be selected as needed, including but not limited to the two ways in the above examples.

[0144] Accordingly, as long as the configuration information carries an RV sequence and an offset parameter, multiple RV sequences can be obtained. Compared with the configuration information carrying multiple RV sequences, it is beneficial to reduce the amount of resources occupied by the configuration information.

[0145] Steps S302 to S304 are specifically implemented in a similar manner to Figure 2 the embodiments shown and will not be elaborated here.

[0146] Figure 4 FIG. is a schematic flowchart of another configuration information sending method shown according to an embodiment of the present disclosure. As Figure 4 shown, the configuration information includes an RV sequence, and the method further includes:

[0147] In step S401, the RV values in the RV sequence are circularly mapped to each transmission occasion configured for the CG PUSCH; or the RV values in the RV sequence are circularly mapped to the transmission occasions in the direction facing each TRP.

[0148] In one embodiment, when the configuration information includes an RV sequence, there are two mapping methods for mapping this RV sequence to the transmission occasions configured for the CG PUSCH used by the terminal for uplink transmission in the direction facing each TRP.

[0149] One mapping method is to not distinguish the transmission occasions configured for the CG PUSCH corresponding to the uplink transmission in the direction of which TRP the terminal faces, and circularly map the RV values in the RV sequence to each transmission occasion configured for the CG PUSCH. Taking the RV sequence {0, 2, 3, 1} as an example, for circular mapping of 8 transmission occasions, the RV value of the 1st transmission occasion is 0, the RV value of the 2nd transmission occasion is 2, the RV value of the 3rd transmission occasion is 3, the RV value of the 4th transmission occasion is 1, the RV value of the 5th transmission occasion is 0, the RV value of the 6th transmission occasion is 2, the RV value of the 7th transmission occasion is 3, and the RV value of the 8th transmission occasion is 1.

[0150] Another mapping method is to distinguish the uplink transmission of the transmission opportunity corresponding to the CG PUSCH configuration for the direction of which TRP the terminal faces, and cyclically map the RV values in the RV sequence to the transmission opportunities for the direction of each TRP. Taking the RV sequence {0, 2, 3, 1} as an example, for 8 transmission opportunities, the 1st, 3rd, 5th, and 7th transmission opportunities are mapped to the uplink transmission for the direction of TRP1, and the 2nd, 4th, 5th, and 6th transmission opportunities are mapped to the uplink transmission for the direction of TRP2. Then for the 4 transmission opportunities for the uplink transmission in the direction of cotton thread TRP1, the RV value of the 1st transmission opportunity is 1, the RV value of the 3rd transmission opportunity is 2, the RV value of the 5th transmission opportunity is 3, and the RV value of the 7th transmission opportunity is 1; for the 4 transmission opportunities for the uplink transmission in the direction of cotton thread TRP2, the RV value of the 2nd transmission opportunity is 0, the RV value of the 4th transmission opportunity is 2, the RV value of the 6th transmission opportunity is 3, and the RV value of the 8th transmission opportunity is 1.

[0151] In one embodiment, the method further includes: sending a plurality of CG PUSCH configurations to the terminal; wherein, the transmission opportunities for the terminal to repeatedly send the same transport block in different directions of the TRPs belong to different CG PUSCH configurations among the plurality of CG PUSCH configurations.

[0152] The base station can only send a plurality of CG PUSCH configurations to the terminal for the terminal to use when repeatedly sending the same transport block in different directions of the TRPs. In this case, each CG PUSCH configuration corresponds to the uplink transmission for the direction of a different TRP respectively. Then for the uplink transmission for the direction of a certain TRP, directly use the transmission opportunity of the corresponding CG PUSCH configuration.

[0153] Taking the directions of 2 TRPs as an example, the base station can send 2 CG PUSCH configurations to the terminal, where CG PUSCH configuration 1 corresponds to the direction of TRP1, and CG PUSCH configuration 2 corresponds to the direction of TRP2. The terminal can use the transmission opportunities in CG PUSCH configuration 1 when repeatedly sending the same transport block in the direction of TRP1, and use the transmission opportunities in CG PUSCH configuration 2 when repeatedly sending the same transport block in the direction of TRP2.

[0154] In one embodiment, the configuration information includes a plurality of RV sequences, and the RV sequences in the plurality of RV sequences are respectively configured for each CG PUSCH configuration of the plurality of CG PUSCH configurations, or includes one RV sequence configured for the plurality of CG PUSCH configurations, or includes one RV sequence configured for the plurality of CG PUSCH configurations and an offset parameter.

[0155] In one embodiment, since the base station configures multiple CG PUSCH configurations for the terminal, when the configuration information includes multiple RV sequences, the RV sequences among these multiple RV sequences need to be respectively configured for each of the multiple CG PUSCH configurations. For example, if the number of RV sequences is the same as the number of CG PUSCH configurations, for example, there are 2, RV sequence 1 can be configured for CG PUSCH configuration 1, and RV sequence 2 can be configured for CG PUSCH configuration 2.

[0156] Similarly, when the configuration information includes one RV sequence, this one RV sequence is the RV sequence configured for the multiple CG PUSCH configurations; when the configuration information includes one RV sequence and an offset parameter, this one RV sequence and the offset parameter are the RV sequence and the offset parameter configured for the multiple CG PUSCH configurations.

[0157] Figure 5 It is a schematic flowchart of another method for sending configuration information shown according to an embodiment of the present disclosure. As Figure 5 shown, the configuration information includes the multiple RV sequences, and the method further includes:

[0158] In step S501, the RV values in the RV sequence are circularly mapped to the transmission opportunities of the CG PUSCH configurations corresponding to the RV sequence.

[0159] In one embodiment, since each RV sequence corresponds to a different CG PUSCH configuration respectively, the RV values in the RV sequence can be directly circularly mapped to the transmission opportunities of the CG PUSCH configurations corresponding to the RV sequence. For example, RV sequence 1 is configured for CG PUSCH configuration 1, and RV sequence 2 is configured for CG PUSCH configuration 2; if RV sequence 1 is {0, 2, 3, 1} and the transmission opportunity of CG PUSCH configuration 1 is from T1 to T8, then {0, 2, 3, 1} can be circularly mapped to T1 to T8; if RV sequence 1 is {0, 3, 0, 3} and the transmission opportunity of CG PUSCH configuration 2 is from T1' to T8', then {0, 3, 0, 3} can be circularly mapped to T1' to T8'.

[0160] Figure 6 It is a schematic flowchart of another method for sending configuration information shown according to an embodiment of the present disclosure. As Figure 6 shown, the configuration information includes one RV sequence and an offset parameter configured for the multiple CG PUSCH configurations, and the method further includes:

[0161] In step S601, multiple RV sequences including the RV sequence are determined according to the RV sequence and the offset parameter;

[0162] In step S602, determine the RV sequence corresponding to each of the multiple CG PUSCH configurations respectively;

[0163] In step S603, cyclically map the RV values in the RV sequence to the transmission opportunities of the corresponding CG PUSCH configuration.

[0164] In one embodiment, when the configuration information includes an RV sequence and an offset parameter, multiple RV sequences including the RV sequence can be determined according to the RV sequence and the offset parameter. For example, a new RV sequence can be determined according to the RV sequence and the offset parameter, and the original RV sequence and the new RV sequence form multiple RV sequences.

[0165] For example, taking the RV sequence {0, 2, 3, 1} as an example, there is an offset parameter 2. Then, the values in the RV sequence can be collectively shifted left by 2 bits to obtain a new RV sequence {3, 1, 0, 2}; or in base-4, 2 can be added to each RV value to obtain a new RV sequence {2, 0, 1, 3}. The way to obtain a new RV sequence according to the RV sequence and the offset parameter can be selected as needed, including but not limited to the two ways in the above examples.

[0166] Accordingly, as long as the configuration information carries an RV sequence and an offset parameter, multiple RV sequences can be obtained. Compared with the configuration information carrying multiple RV sequences, it is beneficial to reduce the resource quantity occupied by the configuration information.

[0167] Since the configuration information does not directly include multiple RV sequences, but multiple RV sequences can be determined according to an RV sequence and an offset parameter, after determining multiple RV sequences, it is also necessary to further determine the RV sequence corresponding to each CG PUSCH configuration in the multiple CG PUSCH configurations in the multiple RV sequences, and then cyclically map the RV values in the RV sequence to the transmission opportunities of the corresponding CG PUSCH configuration.

[0168] For example, for the directions of two TRPs, it can be default to map the RV sequence in the configuration information to the transmission opportunity of the CG PUSCH for uplink transmission in the direction facing TRP1, and map the determined new RV sequence to the transmission opportunity of the CG PUSCH for uplink transmission in the direction facing TRP2.

[0169] Figure 7 It is a schematic flowchart of another configuration information sending method shown according to an embodiment of the present disclosure. As Figure 7 shown, the configuration information includes an RV sequence configured for the multiple CG PUSCH configurations, and the method further includes:

[0170] In step S701, determine the RV sequences respectively corresponding to each of the multiple CG PUSCH configurations.

[0171] In step S702, cyclically map the RV values in the RV sequences to the transmission opportunities of the corresponding CG PUSCH configurations.

[0172] In one embodiment, when the configuration information includes only one RV sequence, since the base station configures multiple CG PUSCH configurations for the terminal, this one RV sequence is configured for the multiple CG PUSCH configurations. For each CG PUSCH configuration, it is also necessary to determine the respectively corresponding RV sequence, which is this one RV sequence. Furthermore, the RV values in this RV sequence can be cyclically mapped to the transmission opportunities of the corresponding CG PUSCH configurations. For example, for each transmission opportunity of CG PUSCH configuration 1, this RV sequence can be used for mapping to determine the RV values of each transmission opportunity. For each transmission opportunity of CG PUSCH configuration 2, this RV sequence can also be used for mapping to determine the RV values of each transmission opportunity.

[0173] In one embodiment, the configuration information is carried in radio resource control (RRC) signaling.

[0174] In one embodiment, the RRC signaling includes multiple first indication information related to the RV sequences, and the multiple first indication information respectively indicate multiple RV sequences; or the RRC signaling includes one second indication information related to the RV sequences, and the second indication information is used to indicate multiple RV sequences.

[0175] In one embodiment, the RRC signaling can independently indicate the RV sequences through the first indication information. For example, new information elements are added to the RRC signaling. For two RV sequences, repK-RV1 can be added to indicate RV sequence 1, and repK-RV2 can be added to indicate RV sequence 2.

[0176] In one embodiment, the RRC signaling can jointly indicate multiple RV sequences through the second indication information. For example, the second indication information is the RV code point. For two RV sequences, each code point value corresponds to an RV sequence 1 and an RV sequence 2. For example, the correspondence between the RV code point and the RV sequences is shown in Table 1 below:

[0177]

[0178] Table 1

[0179] As shown in Table 1, for example, the identifier of the RV sequence is 0, indicating that the RV sequence is {0, 2, 3, 1}; the identifier of the RV sequence is 1, indicating that the RV sequence is {0, 0, 0, 0}; the identifier of the RV sequence is 2, indicating that the RV sequence is {0, 3, 0, 3}.

[0180] Table 1 can be stored in both the base station and the terminal. Thus, according to the RV code point being 0, it can be determined that RV sequence 1 is {0, 2, 3, 1} and RV sequence 2 is {0, 2, 3, 1}; according to the RV code point being 1, it can be determined that RV sequence 1 is {0, 2, 3, 1} and RV sequence 2 is {0, 0, 0, 0}; according to the RV code point being 2, it can be determined that RV sequence 1 is {0, 2, 3, 1} and RV sequence 2 is {0, 3, 0, 3}; according to the RV code point being 3, it can be determined that RV sequence 1 is {0, 0, 0, 0} and RV sequence 2 is {0, 3, 0, 3}.

[0181] It should be noted that the above Table 1 is an example for the case where the base station configures one CG PUSCH configuration for the terminal and the configuration information includes multiple RV sequences. In the case where the base station configures multiple CG PUSCH configurations for the terminal, since each CG PUSCH configuration corresponds to an RV sequence respectively, for each CG PUSCH configuration, an RV sequence can be indicated by a code point, as shown in Table 2 for example:

[0182]

[0183] Table 2

[0184] Since generally there are mainly 3 types of RV sequences, for the case of the code point being 3, the indicated content can be reserved.

[0185] Figure 8 It is a schematic flowchart of another method for sending configuration information shown according to an embodiment of the present disclosure. As Figure 8 shown, the method further includes:

[0186] In step S801, send the update information of the RV sequence to the terminal, where the update information is used to instruct the terminal to update the RV sequences used for repeatedly sending the same transport block at each transmission opportunity corresponding to the CG PUSCH configurations sent in the directions facing different TRPs.

[0187] In one embodiment, the base station can adjust the RV sequence as needed, generate update information according to the adjusted RV sequence, and send the update information to the terminal, so that the terminal can update the RV sequences used for repeatedly sending the same transport block at each transmission opportunity corresponding to the CG PUSCH configurations sent in the directions facing different TRPs.

[0188] It should be noted that the updated information can indicate the updated RV sequence in a manner similar to the above-mentioned first indication information or second indication information, which will not be elaborated here.

[0189] In one embodiment, the updated information is carried in at least one of the following: downlink control information DCI, medium access control layer control element MAC-CE.

[0190] Among them, for the configuration of CG type 1, the updated information can be carried in DCI or in MAC-CE, while for the configuration of CG type 2, the updated information can be carried in DCI.

[0191] In one embodiment, the transmission opportunity is the nominal transmission opportunity for the terminal to send the transmission block. That is, the actual transmission opportunity can be ignored, and only the RV sequence is mapped to the nominal transmission opportunity. For example, for the PUSCH repetition type A transmission mode, generally, the actual transmission opportunity is the same as the nominal transmission opportunity, so only mapping the RV sequence to the nominal transmission opportunity needs to be considered.

[0192] In one embodiment, the transmission opportunity is the actual transmission opportunity for the terminal to send the transmission block. That is, the actual transmission opportunity can be considered, and the RV sequence is mapped to the actual transmission opportunity. For example, for the PUSCH repetition type B transmission mode, in the case where the transmission opportunity crosses the time slot boundary, it will cause the nominal transmission opportunity to be re-segmented to obtain a new actual transmission opportunity. For example, if a nominal transmission opportunity is segmented by a time slot boundary, two new actual transmission opportunities will be obtained, then the RV sequence can be mapped to the actual transmission opportunity to ensure that the mapping result conforms to the actual situation of the used transmission opportunity.

[0193] In one embodiment, the transmission opportunity is the transmission opportunity that has not been discarded due to conflict for the terminal to send the transmission block. That is, only the undiscarded transmission opportunity needs to be considered. For example, for the transmission opportunity in the CG PUSCH configuration configured by the base station, some transmission opportunities have been occupied by the downlink, or there are invalid symbols. Then, when performing uplink transmission, these transmission opportunities need to be discarded, and only the undiscarded transmission opportunity is considered, and the RV sequence is mapped to the transmission opportunity that has not been discarded due to conflict to ensure that the mapping result conforms to the actual situation of the used transmission opportunity.

[0194] In one embodiment, circular mapping starts from the first RV value in the RV sequence; or circular mapping starts from the RV value of 0 in the RV sequence.

[0195] It should be noted that in the above embodiments, for the cyclic mapping of the RV sequence, the cyclic mapping starts from the first RV value in the RV sequence. However, this is only an example of a mapping method. In fact, other mapping methods can also be selected. For example, it can be selected to start the cyclic mapping from the value where RV is 0 in the RV sequence. Taking the RV sequence {0, 3, 0, 3} as an example, it can be selected to start the cyclic mapping from the second RV value of 0 in it.

[0196] Figure 9 It is a schematic flowchart of a method for determining redundant version RV values according to an embodiment of the present disclosure. The method for determining redundant version RV values shown in this embodiment can be applied to a terminal, and the terminal includes, but is not limited to, communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The terminal can communicate with a base station as a user equipment, and the base station includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations.

[0197] As Figure 9 shown, the method for determining redundant version RV values may include the following steps:

[0198] In step S901, receive the configuration information sent by the base station;

[0199] In step S902, according to the configuration information, determine the RV values at each transmission occasion when the terminal repeatedly transmits the same transport block in the directions facing different TRPs; wherein, the transmission occasion belongs to one or more CG PUSCH configurations.

[0200] In one embodiment, the base station can configure information for the terminal; on the one hand, the configuration information can be used by the terminal to determine the RV values at each transmission occasion when repeatedly transmitting the same transport block in the directions facing different TRPs, so that the terminal can perform rate matching according to the corresponding RV values at each transmission occasion. On the other hand, the configuration information can be used by the base station to determine the RV values at each transmission occasion when the terminal repeatedly transmits the same transport block in the directions facing different TRPs, so that when the base station receives the transport block sent by the terminal, it can perform rate matching using the corresponding RV for reception decoding.

[0201] In one embodiment, the method further includes: repeatedly transmitting the same transport block at each transmission occasion in the directions facing different TRPs.

[0202] The terminal can repeatedly transmit the same transport block at each transmission occasion in the directions facing different TRPs, and perform rate matching based on the corresponding RV value at each transmission occasion. The base station can receive the same transport block repeatedly transmitted by the terminal at each transmission occasion in the directions facing different TRPs, and for the transport block transmitted at each transmission occasion, perform rate matching using the RV value corresponding to the transmission occasion during reception for receiving and decoding.

[0203] In one embodiment, the method further includes: receiving a CG PUSCH configuration sent by the base station; wherein, the transmission occasions used by the terminal to repeatedly transmit the same transport block in the directions facing different TRPs belong to the same CG PUSCH configuration.

[0204] The base station can send only one CG PUSCH configuration to the terminal for the terminal to use when repeatedly transmitting the same transport block in the directions facing different TRPs. In this case, it is necessary to allocate the transmission occasions of this one CG PUSCH configuration for the terminal to repeatedly transmit the same transport block in the directions facing different TRPs.

[0205] For example, the transmission occasions of this one CG PUSCH configuration can be evenly allocated for the terminal to repeatedly transmit the same transport block in the direction facing each TRP. Taking the directions of 2 TRPs as an example, for example, if there are 8 transmission occasions in the CG PUSCH configuration, the terminal can use 4 of them when repeatedly transmitting the same transport block in the direction of TRP1, and use the other 4 when repeatedly transmitting the same transport block in the direction of TRP2.

[0206] For example, the transmission occasions of this one CG PUSCH configuration can be multiplexed and allocated for the terminal to repeatedly transmit the same transport block in the direction facing each TRP. Taking the directions of 2 TRPs as an example, for example, if there are 8 transmission occasions in the CG PUSCH configuration, the terminal can use these 8 transmission occasions when repeatedly transmitting the same transport block in the direction of TRP1, and also use these 8 transmission occasions when repeatedly transmitting the same transport block in the direction of TRP2. When the terminal performs uplink transmission in different TRP directions, different antennas can be used, or the same antenna can be used.

[0207] In one embodiment, when the base station sends a CG PUSCH configuration to the terminal, the configuration information belongs to this CG PUSCH configuration, and the configuration information includes multiple RV sequences, or includes one RV sequence, or includes one RV sequence and an offset parameter.

[0208] The RV sequences include, but are not limited to, the following three: {0, 2, 3, 1}, {0, 0, 0, 0}, {0, 3, 0, 3}. The configuration information includes multiple RV sequence cases, which can include multiple of the same RV sequence or multiple different RV sequences. The following embodiments mainly describe the case of including multiple different RV sequences.

[0209] Figure 10 It is a schematic flowchart of another method for determining the redundant version RV value shown according to an embodiment of the present disclosure. As Figure 10 shown, the configuration information includes multiple RV sequences. When determining the RV values at each transmission occasion when the terminal repeatedly transmits the same transport block in the directions facing different TRPs according to the configuration information, the RV values at each transmission occasion include:

[0210] In step S1001, according to the direction of the TRP and the beam mapping rule, group the transmission occasions configured for the CG PUSCH to determine the transmission occasion groups respectively corresponding to the directions of each TRP;

[0211] In step S1002, determine the RV sequences respectively corresponding to each transmission occasion group;

[0212] In step S1003, circularly map the RV values in the RV sequence to each transmission occasion in the corresponding transmission occasion group.

[0213] In one embodiment, when the configuration information includes multiple RV sequences, it is necessary to map the multiple RV sequences to the transmission occasions configured for the CG PUSCH used for uplink transmission in the directions of the terminal facing each TRP. In this case, since there is only one CG PUSCH configuration, it is necessary to group the transmission occasions of the CG PUSCH configuration.

[0214] The transmission occasions of the CG PUSCH configuration can be grouped according to the direction of the TRP and the beam mapping rule to determine the transmission occasion groups respectively corresponding to the directions of each TRP.

[0215] Among them, when the terminal performs uplink transmission in the directions facing different TRPs, different beams can be used. For example, beam 1 can be used for uplink transmission in the direction facing TRP1, and beam 2 can be used for uplink transmission in the direction facing TRP2. The beam mapping rule refers to the mapping relationship between the transmission occasions configured for the CG PUSCH and the beams used for uplink transmission in the directions of the terminal facing different TRPs.

[0216] The beam mapping rules include, but are not limited to, the following three types: periodic mapping, continuous mapping, and half-and-half mapping. Still taking the eight transmission opportunities in the CGPUSCH configuration and the directions of two TRPs as an example, the beams used for the directions of the two TRPs are: beam 1 is used for the direction of TRP1, and beam 2 is used for the direction of TRP2.

[0217] For example, in the case of periodic mapping, the eight transmission opportunities can be mapped to beam 1 and beam 2 in sequence. For example, the 1st, 3rd, 5th, and 7th transmission opportunities are mapped to beam 1, and the 2nd, 4th, 5th, and 6th transmission opportunities are mapped to beam 2.

[0218] For example, in the case of continuous mapping, the mapping pattern for the two beams is beam 1, beam 1, beam 2, beam 2. Then, the eight transmission opportunities can be mapped to beam 1 and beam 2 according to this pattern, that is, the 1st, 2nd, 5th, and 5th transmission opportunities are mapped to beam 1, and the 2nd, 3rd, 7th, and 8th transmission opportunities are mapped to beam 2.

[0219] For example, in the case of half-and-half mapping, half of the eight transmission opportunities can be mapped to beam 1, and the other half of the transmission opportunities can be mapped to beam 2, that is, the 1st, 2nd, 3rd, and 4th transmission opportunities are mapped to beam 1, and the 5th, 6th, 7th, and 8th transmission opportunities are mapped to beam 2.

[0220] Regarding the specific beam mapping rules, they can be selected according to needs, and the present disclosure does not make any restrictions. For the convenience of examples below, the description mainly focuses on the case of periodic mapping.

[0221] Regarding periodic mapping, for the uplink transmission in the direction facing multiple TRPs, a transmission opportunity group can be determined respectively. As mentioned above, for the direction of two TRPs, the eight transmission opportunities in the CG PUSCH configuration can be divided into two transmission opportunity groups. Among them, group 1 corresponds to the direction of TRP1 and includes the 1st, 3rd, 5th, and 7th transmission opportunities, and group 2 corresponds to the direction of TRP2 and includes the 2nd, 4th, 5th, and 6th transmission opportunities.

[0222] The number of multiple RV sequences included in the configuration information can correspond to the number of transmission opportunity groups. For example, for 2 transmission opportunity groups, 2 RV sequences can be configured. For example, RV sequence 1 corresponds to transmission opportunity group 1, and RV sequence 2 corresponds to transmission opportunity group 2.

[0223] For example, if the RV sequence 1 is {0, 2, 3, 1} and the RV sequence 2 is {0, 3, 0, 3}, then the RV values in the RV sequence {0, 2, 3, 1} can be cyclically mapped to the 1st, 3rd, 5th, and 7th transmission opportunities. That is, the RV value of the 1st transmission opportunity is 0, the RV value of the 3rd transmission opportunity is 2, the RV value of the 5th transmission opportunity is 3, and the RV value of the 6th transmission opportunity is 1. Similarly, the RV values in the RV sequence {0, 3, 0, 3} can be cyclically mapped to the 2nd, 4th, 6th, and 8th transmission opportunities. That is, the RV value of the 2nd transmission opportunity is 0, the RV value of the 4th transmission opportunity is 3, the RV value of the 6th transmission opportunity is 0, and the RV value of the 8th transmission opportunity is 3.

[0224] Figure 11 It is a schematic flowchart of another method for determining the redundant version RV value shown according to an embodiment of the present disclosure. As Figure 11 shown, the configuration information includes an RV sequence and an offset parameter. When determining the RV values at each transmission opportunity for the terminal to repeatedly transmit the same transport block in the directions facing different TRPs according to the configuration information, the RV values at each transmission opportunity include:

[0225] In step S1101, multiple RV sequences including the RV sequence are determined according to the RV sequence and the offset parameter;

[0226] In step S1102, the transmission opportunities configured for CG PUSCH are grouped according to the direction of the TRP and the beam mapping rule to determine the transmission opportunity groups respectively corresponding to the directions of each TRP;

[0227] In step S1103, the RV sequence respectively corresponding to each transmission opportunity group is determined;

[0228] In step S1104, the RV values in the RV sequence are cyclically mapped to the transmission opportunities in the corresponding transmission opportunity group.

[0229] In one embodiment, when the configuration information includes an RV sequence and an offset parameter, multiple RV sequences including the RV sequence can be determined according to the RV sequence and the offset parameter. For example, a new RV sequence can be determined according to the RV sequence and the offset parameter, and the original RV sequence and the new RV sequence form multiple RV sequences.

[0230] For example, taking the RV sequence {0, 2, 3, 1} as an example, there is an offset parameter 2. Then, the values in the RV sequence can be collectively shifted left by 2 bits to obtain a new RV sequence {3, 1, 0, 2}; or according to base-4, 2 can be added to each RV value to obtain a new RV sequence {2, 0, 1, 3}. The way to obtain a new RV sequence based on the RV sequence and the offset parameter can be selected as needed, including but not limited to the two ways in the above examples.

[0231] Accordingly, as long as the configuration information carries an RV sequence and an offset parameter, multiple RV sequences can be obtained. Compared with the configuration information carrying multiple RV sequences, it is beneficial to reduce the amount of resources occupied by the configuration information.

[0232] Steps S1102 to S1104, the specific implementation manners are similar to Figure 10 the embodiments shown and will not be elaborated here.

[0233] Figure 12 is a schematic flowchart of another method for determining redundant version RV values according to an embodiment of the present disclosure. As Figure 12 shown, the configuration information includes an RV sequence. When determining the RV values at each transmission occasion when the terminal repeatedly transmits the same transport block in the directions facing different TRPs according to the configuration information, the RV values at each transmission occasion include:

[0234] In step S1201, the RV values in the RV sequence are circularly mapped to each transmission occasion configured for the CG PUSCH; or the RV values in the RV sequence are circularly mapped to the transmission occasions in the directions facing each TRP.

[0235] In one embodiment, in the case where the configuration information includes an RV sequence, when mapping this RV sequence to the transmission occasions configured for the CG PUSCH used for uplink transmission in the directions facing each TRP by the terminal, there are two mapping methods.

[0236] One mapping method is not to distinguish the transmission occasions configured for the CG PUSCH corresponding to the uplink transmission in the directions facing which TRP by the terminal, and circularly map the RV values in the RV sequence to each transmission occasion configured for the CG PUSCH. Taking the RV sequence {0, 2, 3, 1} as an example, for circular mapping to 8 transmission occasions, the RV value of the 1st transmission occasion is 0, the RV value of the 2nd transmission occasion is 2, the RV value of the 3rd transmission occasion is 3, the RV value of the 4th transmission occasion is 1, the RV value of the 5th transmission occasion is 0, the RV value of the 6th transmission occasion is 2, the RV value of the 7th transmission occasion is 3, and the RV value of the 8th transmission occasion is 1.

[0237] Another mapping method is to distinguish the uplink transmission of the transmission opportunity corresponding to the CG PUSCH configuration according to the direction of the terminal facing which TRP, and cyclically map the RV values in the RV sequence to the transmission opportunities in the direction of each TRP. Taking the RV sequence {0, 2, 3, 1} as an example, for 8 transmission opportunities with cyclic mapping, the 1st, 3rd, 5th, and 7th transmission opportunities are mapped to the uplink transmission in the direction of TRP1, and the 2nd, 4th, 5th, and 6th transmission opportunities are mapped to the uplink transmission in the direction of TRP2. Then for the 4 transmission opportunities for uplink transmission in the direction of cotton thread TRP1, the RV value of the 1st transmission opportunity is 1, the RV value of the 3rd transmission opportunity is 2, the RV value of the 5th transmission opportunity is 3, and the RV value of the 7th transmission opportunity is 1; for the 4 transmission opportunities for uplink transmission in the direction of cotton thread TRP2, the RV value of the 2nd transmission opportunity is 0, the RV value of the 4th transmission opportunity is 2, the RV value of the 6th transmission opportunity is 3, and the RV value of the 8th transmission opportunity is 1.

[0238] In one embodiment, the method further includes: receiving multiple CG PUSCH configurations sent by the base station; wherein, the transmission opportunities used by the terminal to repeatedly send the same transmission block in different directions of the TRP belong to different CG PUSCH configurations among the multiple CG PUSCH configurations.

[0239] The base station can only send multiple CG PUSCH configurations to the terminal for use when the terminal repeatedly sends the same transmission block in different directions of the TRP. In this case, each CG PUSCH configuration corresponds to the uplink transmission in the direction of a different TRP. Then, for the uplink transmission in the direction of a certain TRP, directly use the transmission opportunity of the corresponding CG PUSCH configuration.

[0240] Taking the direction of 2 TRPs as an example, the base station can send 2 CG PUSCH configurations to the terminal, where CG PUSCH configuration 1 corresponds to the direction of TRP1 and CG PUSCH configuration 2 corresponds to the direction of TRP2. The terminal can use the transmission opportunities in CG PUSCH configuration 1 when repeatedly sending the same transmission block in the direction of TRP1, and use the transmission opportunities in CG PUSCH configuration 2 when repeatedly sending the same transmission block in the direction of TRP2.

[0241] In one embodiment, the configuration information includes multiple RV sequences, the RV sequences in the multiple RV sequences are respectively configured for each CG PUSCH configuration of the multiple CG PUSCH configurations, or includes one RV sequence configured for the multiple CG PUSCH configurations, or includes one RV sequence configured for the multiple CG PUSCH configurations and an offset parameter.

[0242] In one embodiment, since the base station configures multiple CG PUSCH configurations for the terminal, when the configuration information includes multiple RV sequences, the RV sequences among these multiple RV sequences need to be respectively configured for each of the multiple CG PUSCH configurations. For example, the number of RV sequences is the same as the number of CG PUSCH configurations. For example, if there are 2, RV sequence 1 can be configured for CG PUSCH configuration 1, and RV sequence 2 can be configured for CG PUSCH configuration 2.

[0243] Similarly, when the configuration information includes one RV sequence, this one RV sequence is the RV sequence configured for multiple CG PUSCH configurations; when the configuration information includes one RV sequence and an offset parameter, this one RV sequence and the offset parameter are the RV sequence and the offset parameter configured for multiple CG PUSCH configurations.

[0244] Figure 13 It is a schematic flowchart of another method for determining the redundancy version RV value shown according to an embodiment of the present disclosure. As Figure 13 shown, when determining the RV values at each transmission opportunity when the terminal repeatedly transmits the same transport block in the directions facing different TRPs according to the configuration information, the RV values at each of the transmission opportunities include:

[0245] In step S1301, the RV values in the RV sequence are cyclically mapped to the transmission opportunities of the CG PUSCH configuration corresponding to the RV sequence.

[0246] In one embodiment, since each RV sequence corresponds to a different CG PUSCH configuration respectively, the RV values in the RV sequence can be directly cyclically mapped to the transmission opportunities of the CG PUSCH configuration corresponding to the RV sequence. For example, RV sequence 1 is configured for CG PUSCH configuration 1, and RV sequence 2 is configured for CG PUSCH configuration 2; RV sequence 1 is {0, 2, 3, 1}, and the transmission opportunities of CG PUSCH configuration 1 are from T1 to T8, then {0, 2, 3, 1} can be cyclically mapped to T1 to T8; RV sequence 1 is {0, 3, 0, 3}, and the transmission opportunities of CG PUSCH configuration 2 are from T1' to T8', then {0, 3, 0, 3} can be cyclically mapped to T1' to T8'.

[0247] Figure 14 It is a schematic flowchart of another method for determining the redundancy version RV value shown according to an embodiment of the present disclosure. As Figure 14As shown, the configuration information includes an RV sequence and an offset parameter configured for the multiple CG PUSCH configurations. When determining that the terminal repeatedly transmits the same transport block at each transmission opportunity in the directions facing different TRPs according to the configuration information, the RV values at each transmission opportunity include:

[0248] In step S1401, multiple RV sequences including the RV sequence are determined according to the RV sequence and the offset parameter;

[0249] In step S1402, the RV sequence corresponding to each CG PUSCH configuration in the multiple CG PUSCH configurations is determined;

[0250] In step S1403, the RV values in the RV sequence are circularly mapped to the transmission opportunities of the corresponding CG PUSCH configuration.

[0251] In one embodiment, when the configuration information includes an RV sequence and an offset parameter, multiple RV sequences including the RV sequence can be determined according to the RV sequence and the offset parameter. For example, a new RV sequence can be determined according to the RV sequence and the offset parameter, and the original RV sequence and the new RV sequence form multiple RV sequences.

[0252] For example, taking the RV sequence {0, 2, 3, 1} as an example, there is an offset parameter 2. Then, the values in the RV sequence can be collectively shifted left by 2 bits to obtain a new RV sequence {3, 1, 0, 2}; or in base 4, 2 can be added to each RV value to obtain a new RV sequence {2, 0, 1, 3}. The method of obtaining a new RV sequence according to the RV sequence and the offset parameter can be selected as needed, including but not limited to the two methods in the above example.

[0253] Accordingly, as long as the configuration information carries an RV sequence and an offset parameter, multiple RV sequences can be obtained. Compared with the configuration information carrying multiple RV sequences, it is beneficial to reduce the resource quantity occupied by the configuration information.

[0254] Since the configuration information does not directly include multiple RV sequences, but multiple RV sequences can be determined according to an RV sequence and an offset parameter, after determining multiple RV sequences, it is also necessary to further determine the RV sequence corresponding to each CGPUSCH configuration in the multiple CG PUSCH configurations in the multiple RV sequences, and then circularly map the RV values in the RV sequence to the transmission opportunities of the corresponding CG PUSCH configuration.

[0255] For example, for the directions of two TRPs, it can be default that the RV sequence in the configuration information is mapped to the transmission opportunity of the CG PUSCH for uplink transmission in the direction facing TRP1, and the determined new RV sequence is mapped to the transmission opportunity of the CG PUSCH for uplink transmission in the direction facing TRP2.

[0256] Figure 15 It is a schematic flowchart of another method for determining redundant version (RV) values shown according to an embodiment of the present disclosure. As Figure 15 shown, the configuration information includes an RV sequence configured for the configuration of multiple CG PUSCHs. When determining the RV values at each transmission opportunity for the terminal to repeatedly transmit the same transport block in the directions facing different TRPs according to the configuration information, the RV values at each transmission opportunity include:

[0257] In step S1501, determine the RV sequence corresponding to each CG PUSCH configuration among the multiple CG PUSCH configurations;

[0258] In step S1502, cyclically map the RV values in the RV sequence to the transmission opportunities of the corresponding CG PUSCH configurations.

[0259] In one embodiment, when the configuration information includes only one RV sequence, since the base station configures multiple CG PUSCH configurations for the terminal, this one RV sequence is configured for multiple CG PUSCH configurations. For each CGPUSCH configuration, it is also necessary to determine the corresponding RV sequence, which is all this one RV sequence. Furthermore, the RV values in this RV sequence can be cyclically mapped to the transmission opportunities of the corresponding CG PUSCH configurations. For example, for each transmission opportunity of CG PUSCH configuration 1, this RV sequence can be used for mapping to determine the RV values at each transmission opportunity. For each transmission opportunity of CG PUSCH configuration 2, this RV sequence can also be used for mapping to determine the RV values at each transmission opportunity.

[0260] In one embodiment, the configuration information is carried in the radio resource control (RRC) signaling.

[0261] In one embodiment, the RRC signaling includes multiple first indication information related to the RV sequence, and the multiple first indication information respectively indicate multiple RV sequences; or the RRC signaling includes one second indication information related to the RV sequence, and the second indication information is used to indicate multiple RV sequences.

[0262] In one embodiment, the RRC signaling can independently indicate the RV sequence through the first indication information. For example, a new information element can be added to the RRC signaling. For two RV sequences, repK-RV1 can be added to indicate RV sequence 1, and repK-RV2 can be added to indicate RV sequence 2.

[0263] In one embodiment, the RRC signaling can jointly indicate multiple RV sequences through the second indication information. For example, the second indication information is the RV code point codepoint. For two RV sequences, each code point value corresponds to an RV sequence 1 and an RV sequence 2. For example, the correspondence between the RV code point and the RV sequence is shown in Table 1 above.

[0264] For example, if the identifier of the RV sequence is 0, the RV sequence is {0, 2, 3, 1}; if the identifier of the RV sequence is 1, the RV sequence is {0, 0, 0, 0}; if the identifier of the RV sequence is 2, the RV sequence is {0, 3, 0, 3}.

[0265] Table 1 can be stored in both the base station and the terminal. Thus, according to the RV code point being 0, it can be determined that RV sequence 1 is {0, 2, 3, 1} and RV sequence 2 is {0, 2, 3, 1}; according to the RV code point being 1, it can be determined that RV sequence 1 is {0, 2, 3, 1} and RV sequence 2 is {0, 0, 0, 0}; according to the RV code point being 2, it can be determined that RV sequence 1 is {0, 2, 3, 1} and RV sequence 2 is {0, 3, 0, 3}; according to the RV code point being 3, it can be determined that RV sequence 1 is {0, 0, 0, 0} and RV sequence 2 is {0, 3, 0, 3}.

[0266] It should be noted that the above Table 1 is an example for the case where the base station configures one CG PUSCH configuration for the terminal and the configuration information includes multiple RV sequences. In the case where the base station configures multiple CG PUSCH configurations for the terminal, since each CG PUSCH configuration corresponds to an RV sequence respectively, for each CG PUSCH configuration, an RV sequence can be indicated by a code point. For example, as shown in Table 2 above, since generally there are mainly 3 types of RV sequences, for the case of the code point being 3, the indicated content can be reserved.

[0267] Figure 16 It is a schematic flowchart of another method for determining the redundant version RV value shown according to an embodiment of the present disclosure. As Figure 16 shown, the method further includes:

[0268] In step S1601, receive the update information of the RV sequence sent by the base station;

[0269] In step S1602, according to the update information, update the RV sequence used for repeatedly transmitting the same transport block on each transmission occasion corresponding to the CGPUSCH configuration transmitted in the directions facing different TRPs.

[0270] In one embodiment, the base station can adjust the RV sequence as needed, generate update information according to the adjusted RV sequence, and send the update information to the terminal, so that the terminal can update the RV sequence used for repeatedly transmitting the same transport block on each transmission occasion corresponding to the CGPUSCH configuration transmitted in the directions facing different TRPs.

[0271] It should be noted that the update information can indicate the updated RV sequence in a manner similar to the above-mentioned first indication information or second indication information, which will not be elaborated here.

[0272] In one embodiment, the update information is carried in at least one of the following: downlink control information DCI, medium access control layer control element MAC-CE.

[0273] Among them, for the configuration of CG type 1, the update information can be carried in DCI or in MAC-CE, while for the configuration of CG type 2, the update information can be carried in DCI.

[0274] In one embodiment, the transmission occasion is the nominal transmission occasion for the terminal to transmit the transport block. That is, the actual transmission occasion can be not considered, and the RV sequence is only mapped to the nominal transmission occasion. For example, for the PUSCH repetition type A transmission mode, generally, the actual transmission occasion is the same as the nominal transmission occasion, so only the mapping of the RV sequence to the nominal transmission occasion needs to be considered.

[0275] In one embodiment, the transmission occasion is the actual transmission occasion for the terminal to transmit the transport block. That is, the actual transmission occasion can be considered, and the RV sequence is mapped to the actual transmission occasion. For example, for the PUSCH repetition type B transmission mode, in the case where the transmission occasion crosses the time slot boundary, it will cause the nominal transmission occasion to be re-segmented to obtain a new actual transmission occasion. For example, if a nominal transmission occasion is divided by a time slot boundary, two new actual transmission occasions will be obtained, then the RV sequence can be mapped to the actual transmission occasion to ensure that the mapping result conforms to the actual situation of the transmission occasion used.

[0276] In one embodiment, the transmission opportunity is the transmission opportunity that is not discarded due to a conflict on the actual transmission opportunity when the terminal sends the transmission block. That is, only the transmission opportunities that are not discarded need to be considered. For example, for the transmission opportunities in the CG PUSCH configuration configured by the base station, some transmission opportunities have been occupied by the downlink, or there are invalid symbols. Then, when performing uplink transmission, these transmission opportunities need to be discarded, so as to only consider the transmission opportunities that are not discarded, and map the RV sequence to the transmission opportunities that are not discarded due to a conflict, so as to ensure that the mapping result is consistent with the actual situation of the used transmission opportunities.

[0277] In one embodiment, circular mapping starts from the first RV value in the RV sequence; or circular mapping starts from the value of RV equal to 0 in the RV sequence.

[0278] It should be noted that in the above embodiments, for the circular mapping of the RV sequence, circular mapping always starts from the first RV value in the RV sequence, but this is only an example of a mapping method. In fact, other mapping methods can also be selected. For example, it can be selected to start circular mapping from the value of RV equal to 0 in the RV sequence. Taking the RV sequence {0, 3, 0, 3} as an example, it can be selected to start circular mapping from the second RV value equal to 0 among them.
