[0225] In some examples, terminal device 11 determines the first information, terminal device 11 sends the first information to network device 12, and network device 12 receives the first information sent by terminal device 11; network device 12 repeatedly receives the first channel based on the first information to achieve coverage enhancement of Msg5 and subsequent PUSCH; or, network device 12 determines the first information, network device 12 sends the first information to terminal device 11, terminal device 11 receives the first information sent by network device 12, and repeatedly transmits the first channel based on the first information to achieve coverage enhancement of Msg5 and subsequent PUSCH. The first information may be the number of repetitions of the first channel, and the subsequent PUSCH may be a physical uplink shared channel (PUSCH) scheduled by downlink control information (DCI) format 0_0 or DCI format 0_1, with the cyclic redundancy check (CRC) scrambled by the cell-radio network temporary identifier (C-RNTI). The first channel may be used to carry at least one of the following messages: RRCSetupComplete; RRCResumeComplete; RRCReestablishmentComplete; core network connection establishment signaling; non-access stratum (NAS) layer signaling; security messages; and terminal capability signaling. The transmission of the first channel and the messages it carries may occur after the terminal receives Msg4 sent by the network device and before the terminal device receives RRC reconfiguration signaling sent by the network device. RRCSetupComplete; RRCResumeComplete; RRCReestablishmentComplete are messages carried by Msg5; the core network connection establishment signaling is used for the terminal to establish a connection with the core network after the RRC connection establishment is completed; NAS layer signaling is used for data transmission between the core network and the terminal; security messages are used for security verification and interaction between the terminal and the core network; after the terminal establishes a connection with the core network and passes the security verification, the terminal can send terminal capability signaling to the network device to indicate the terminal capability information of the blind retransmission of the first channel, and the network device can further reconfigure RRC for the terminal based on the terminal capability information.

[0226] This embodiment provides a channel blind retransmission solution, which can implement retransmission processing on the first channel, enhance the coverage of Msg5 and subsequent PUSCH, and improve data transmission performance.

[0227] Furthermore, to illustrate the specific execution process of the above-mentioned communication processing system, FIG2 shows a timing diagram of a communication processing method according to an embodiment of the present disclosure. The method is applied to the above-mentioned communication processing system, as shown in FIG2, and may include the following steps:

[0228] Step 101: The terminal device determines first information.

[0229] In some embodiments, the first information is used to indicate blind retransmission of the first channel. The first channel may include Msg5 and subsequent PUSCH. The blind retransmission may enhance the coverage of Msg5 and subsequent PUSCH. The subsequent PUSCH may be a PUSCH scheduled by DCI format 0_0 or DCIformat 0_1 ​​whose CRC is scrambled by C-RNTI. The subsequent PUSCH is an uplink channel after the terminal device receives Msg4 until it receives the terminal device-specific radio resource control (Radio Resource Control, RRC) reconfiguration signaling. These uplink channels are used to transmit uplink and downlink data before RRC reconfiguration, such as can be used to carry uplink messages such as Msg5 (RRCSetupComplete, RRCResumeComplete or RRCReestablishmentComplete), core network connection establishment signaling, security messages, non-access stratum (NAS) messages (NAS layer signaling) and terminal capability signaling. The transmission of the first channel may occur after the terminal receives Msg4 sent by the network device and before the terminal device receives the RRC reconfiguration signaling sent by the network device.

[0230] In some embodiments, the first information may be a type of communication information, such as an indication information or a signaling, etc. For example, the first information may include: Radio Resource Control (RRC) signaling; and / or Media Access Control Element (MAC CE) signaling; and / or Downlink Control Information (DCI) signaling. In addition, the first information may also be the number of retransmissions of the first channel. In the following embodiment steps in the present disclosure, the technical solution in the present disclosure is described by taking the first information as the number of retransmissions of the first channel as an example, but it does not constitute a specific limitation. The terminal device can determine the number of retransmissions of the first channel, and repeat the transmission operation of the first channel with the network device based on the number of retransmissions. The coverage can be increased by repeated transmission, that is, the same data is sent repeatedly to improve the transmission performance, so as to achieve coverage enhancement of Msg5 and subsequent PUSCH.

[0231] In some embodiments, the terminal device may independently determine the number of retransmissions of the first channel based on a comparison of a Reference Signal Receiving Power (RSRP) measurement result with a threshold. Different RSRP thresholds may correspond to different transmission times. The RSRP threshold and the number of retransmissions, as well as the correspondence between the two, may be configured by the network device through System Information Block 1 (SIB1) / Other System Information (OSI) / Radio Resource Control (RRC) (such as RRC signaling carried in Msg4), or may be specified in the protocol.

[0232] In some embodiments, only when the network device is configured with an RSRP threshold and / or number of retransmissions, that is, the network device has been upgraded to R19 and is capable of receiving the number of retransmissions and performing repeated transmission of Msg5 and / or subsequent PUSCH data with the terminal device based on the number of retransmissions, will the terminal device determine the number of retransmissions and report the number of retransmissions; and / or, the base station can configure the display enable signaling of the number of retransmissions corresponding to the first channel through SIB1 / OSI / RRC. Only when the base station indicates that repetition transmission of the first channel is enabled, will the terminal report the number of retransmissions of the first channel. Otherwise, the determination and reporting of the number of retransmissions of the first channel will not be performed. In addition, a possible embodiment is that if the RSRP threshold and / or number of retransmissions are not configured, and the base station indicates that the number of retransmissions of Msg5 and / or subsequent PUSCH is enabled, the terminal determines the number of retransmissions of the first channel based on the default RSRP threshold and / or default repetition value, and reports the number of retransmissions of the first channel.

[0233] Step 102: The terminal device sends first information to the network device.

[0234] In some embodiments, the terminal device may send the first information to the network device (such as a base station) through any one of Msg1, Msg3, and Msg5. Both the terminal device and the network device repeatedly transmit the first channel this number of times, thereby enhancing the coverage of Msg5 and subsequent PUSCH, improving the performance of data transmission, and improving spectrum efficiency.

[0235] When the terminal device sends the first information to the network device:

[0236] In some embodiments, the terminal device may implicitly report through one or more separate groups of Physical Random Access Channel (PRACH) resources configured by the network device. Different numbers of repeated transmissions may correspond to different PRACH resource combinations, and different numbers of repeated transmissions may be distinguished by at least one or more of the following resources: time domain, frequency domain, and code domain. The specific corresponding rules may be agreed upon by the terminal device and the network device, and / or configured to the terminal device by the network device, and are not specifically limited here. A possible embodiment is, as shown in Figure 3, adding a Msg5-repetition-r19 field in the RRC IEFeatureCombination-r17 configured by the network device to configure a separate PRACH resource for repeated transmission of the first channel.

[0237] In some embodiments, when the terminal device sends the first information to the network device, it can be distinguished by the demodulation reference signal (DMRS) of Msg3 (such as distinguishing different time domains, frequency domains, and code domains, etc.), and different numbers of repeated transmissions can correspond to different DMRSs. The specific corresponding rules can be agreed upon by the terminal device and the network device, or can be configured to the terminal device by the network device, or the relationship between DMRS resources and the number of retransmissions can be determined through the joint action of protocol provisions and network device configuration. No specific limitation is made here.

[0238] In some embodiments, the terminal device may generate a new RNTI based on the temporary cell radio network temporary identifier (TC-RNTI) indicated by the random access response (RAR) and certain rules, scramble the Msg3 physical uplink shared channel codeword based on the new RNTI, and report the number of repeated transmissions based on this, where different repeated transmission numbers may correspond to different RNTIs. The rules for generating the new RNTI may be defined in the protocol.

[0239] In some embodiments, the terminal device may indicate the number of repeated transmissions through a reserved bit of the MAC subheader corresponding to the Media Access Control (MAC) Service Data Unit (SDU) or MAC Control Element (MACCE) of Msg3 or Msg5.

[0240] In some embodiments, the terminal device may indicate the first information through a newly generated logical channel identifier (LCID) in the MAC subheader corresponding to the media access control MAC SDU or MAC CE of Msg3 or Msg5, where different LCIDs are used to indicate different numbers of repeated transmissions.

[0241] In some embodiments, the terminal device may use the new or original MAC CE in Msg3 or Msg5 to indicate the number of repeated transmissions.

[0242] In some embodiments, the terminal device may use the reserved bit in Msg3 corresponding to the message RRCResumeRequest, RRCSetupRequest, or RRCReestablishmentRequest, or a newly added bit to indicate the number of repeated transmissions.

[0243] In some embodiments, the terminal device may use the reserved bit in Msg5 corresponding to carry the messages RRCResumeComplete, RRCSetupComplete, and RRCReestablishmentComplete, or a newly added bit to indicate the number of repeated transmissions.

[0244] In some embodiments, the terminal device may use new RRC signaling carried in the Msg3 or Msg5 MAC PDU to indicate the number of repeated transmissions.

[0245] In some embodiments, the terminal device may indicate the number of repeated transmissions by appending a physical layer bit in the payload after handing over the Msg5 MAC PDU to the physical layer.

[0246] In some embodiments, when the above-mentioned terminal device sends the first information to the network device, if the indication is displayed through bits, the index value of the configuration of the number of repeated transmissions (the index in the repetition number list) can also be indicated to the network device, thereby saving bit overhead. For example, when the retransmission number list (repetition number list) configured by the network device is {2, 4, 8}, the index value configured by the terminal device can be decimal 0, 1, 2 or binary "00", "01", "10", and the index value 0 or "00" corresponds to 2 in the repetition number list, the index value 1 or "01" corresponds to 4 in the repetition number list, and the index value 2 or "10" corresponds to 8 in the repetition number list.

[0247] Among them, the repetition number list can be configured by the RRC signaling in SIB1 or Msg4. Optionally, if not configured, the repetition number list configured in Msg3 or the default repetition number list is used. Optionally, the use priority of the repetition number list configured in Msg3 is higher than the default repetition number list. In addition, a possible implementation method is that the RRC signaling in SIB1 and Msg4 can both configure the repetition number list for the number of repeated transmissions. If the RRC signaling of SIB1 and Msg4 are both configured with the Msg5 repetition number list, the use priority can be defined. One possible way is: the use priority of the repetition number list configured by Msg4RRC is greater than the repetition number list configured by SIB1RRC. Optionally, the configured repetition number list may include the retransmission number 1. In some embodiments, the repetition count list is configured in at least one of the following ways: the RRC signaling carried by Msg4 is a first list configured for the first channel; SIB1 is a second list configured for the first channel; SIB1 is a third list configured for the second channel, and the second channel is used to carry Msg3; the fourth list corresponding to the default first channel; and the fifth list corresponding to the default second channel. The first list has a higher priority than the second list; the second list has a higher priority than the third list; the third list has a higher priority than the fourth list; the first list has a higher priority than the fourth list; the second list has a higher priority than the fourth list; and the fourth list has a higher priority than the fifth list.

[0248] Step 103: The terminal device repeatedly transmits the first channel according to the first information.

[0249] Step 104: The network side repeatedly receives the first channel according to the first information.

[0250] In some embodiments, the terminal device repeatedly transmits the first channel according to the number of retransmissions in the first information, and the network device (such as a base station) repeatedly receives the first channel according to the number of retransmissions in the first information. The coverage can be increased by repeated transmission, that is, the same data is sent repeatedly to improve the transmission performance, thereby enhancing the coverage of Msg5 and subsequent PUSCH, improving the performance of data transmission, and improving the spectrum efficiency.

[0251] This embodiment provides a channel blind retransmission solution. The terminal device determines the first information and retransmits the first channel based on the first information, thereby enhancing the coverage of the first channel and improving the performance of data transmission.

[0252] Furthermore, to illustrate the specific execution process of the above-mentioned communication processing system, FIG4 shows a timing diagram of a communication processing method according to an embodiment of the present disclosure. The method is applied to the above-mentioned communication processing system, as shown in FIG4, and may include the following steps:

[0253] Step 201: The network device sends first information to the terminal device.

[0254] In some embodiments, the first information is used to indicate blind retransmission of a first channel, and the first channel can be used to carry at least one of the following messages: RRCSetupComplete; RRCResumeComplete; RRCReestablishmentComplete; core network connection establishment signaling; non-access stratum (NAS) layer signaling; security message; terminal capability signaling. Transmission of the first channel may occur after the terminal receives Msg4 sent by the network device and before the terminal device receives RRC reconfiguration signaling sent by the network device.

[0255] In some embodiments, the first information may be a type of communication information, such as an indication information or a signaling, etc. For example, the first information may include: SIB1; and / or RRC signaling; and / or MAC CE signaling; and / or DCI signaling. In addition, the first information may also be the number of retransmissions of the first channel. In the following embodiment steps of the present disclosure, the technical solution in the present disclosure is described by taking the first information as the number of retransmissions of the first channel as an example, but it does not constitute a specific limitation. That is, the terminal device can determine the number of retransmissions of the first channel, and repeat the transmission operation of the first channel with the network device based on the number of retransmissions. The coverage can be increased by repeated transmission, that is, the same data is sent repeatedly to improve the transmission performance, so as to achieve coverage enhancement of Msg5 and subsequent PUSCH.

[0256] In some embodiments, the network device can determine the first information and indicate the first information to the terminal device. The terminal device repeatedly transmits the first channel according to the first information, and the network side repeatedly receives the first channel according to the first information. This can enhance the coverage of the first channel, improve the performance of data transmission, and improve spectrum efficiency.

[0257] In some embodiments, when the network device indicates the number of retransmissions to the terminal device, it may be indicated in a semi-static manner, that is, indicating a number of retransmissions. In some embodiments, the network device (such as a base station) may directly indicate a number of retransmissions through the RRC signaling of SIB1 / OSI / Msg4, and the terminal device with this capability directly performs PUSCH transmission based on this number. Optionally, the terminal device with this capability may determine whether to repeat the transmission of the first channel based on the number of retransmissions after receiving the number of retransmissions indicated by the network device through the RSRP threshold judgment. Optionally, the RSRP threshold may be configured by the base station or specified by the protocol. In some embodiments, the network device (such as a base station) may configure a number of retransmissions through the RRC signaling carried in Msg4 based on the terminal capability report and / or the auxiliary information report and / or the first channel blind retransmission request. The terminal transmits the first channel based on the number of retransmissions.

[0258] As a possible implementation, the RRC signaling of both SIB1 and Msg4 can configure the number of repeated transmissions for the first channel. If the RRC signaling of both SIB1 and Msg4 configures the number of repeated transmissions for the first channel, a usage priority can be defined. One possible implementation is: the usage priority configured by the Msg4 RRC signaling is higher than the usage priority configured by SIB1. When the RRC signaling of neither SIB1 nor Msg4 configures the number of repeated transmissions, the first channel repeated transmission number configured by Msg3 or the default first channel repeated transmission number can be used; the optional usage priority configured by Msg3 c must be higher than the default usage priority. For example, the default number of repeated transmissions of the first channel is 1; or the default number of repeated transmissions of the first channel is not 1, when the terminal supports Msg5 repetition, or reports the terminal capability indication, or initiates a repetition request, or reports auxiliary information, or configures the repetition value list / RSRP threshold, or the Msg5 repetition function is displayed by the base station to enable the first channel repetition, or the DCI bearer bit indicates that the existing field is used for repetition indication, and the repetition number is not configured, the default number of repeated transmissions of the first channel can be used.

[0259] In some embodiments, when the network device indicates the number of retransmissions to the terminal device, it may indicate in a dynamic manner, that is, dynamically indicate multiple retransmission times. Optionally, the network device will indicate the number of retransmissions (which may include the case where the indication is 1) only after the terminal device has performed capability reporting / auxiliary information reporting / first channel blind retransmission request. The network device may indicate the first information to the terminal device by scheduling downlink control information (Downlink Control Information, DCI) of the Physical Uplink Shared Channel (PUSCH).

[0260] In some embodiments, when the network device schedules the number of retransmissions indicated by the DCI of the PUSCH, specifically, at least one of the following methods may be used:

[0261] In some embodiments, a network device (such as a base station) may reuse existing fields in the DCI to indicate the number of retransmissions to the terminal device, such as the Transmission Power Control (TPC), Modulation and Coding Scheme (MCS), Time Domain Resource Assignment (TDRA), and Frequency Domain Resource Allocation (FDRA). For example, the lower or upper bits of any of the above fields may be used to indicate the number of retransmissions.

[0262] In some embodiments, when the terminal device supports first channel retransmission, or reports terminal capability indication, or initiates a data retransmission request, or reports auxiliary information, or the network device configures the index value / RSRP threshold for data retransmission, or the first channel retransmission function is explicitly enabled by the network device, or the DCI bearer bit indicates that the existing field is used for data retransmission indication, the terminal device interprets the field based on the new definition; terminal devices other than the above situations may interpret the field based on the original meaning.

[0263] In some embodiments, a network device (such as a base station) may reuse an existing field in the DCI to indicate an index value (repetition value list) of the first information, where the index value is the index value of an existing list or the index value of a newly added list. The corresponding field of the first information may be reused in the existing list, or the first information may be configured in the newly added list. In some embodiments, the newly added list and / or the existing list include at least one of the following: a first list configured for the first channel by the RRC signaling carried by Msg4; a second list configured for the first channel by SIB1; a third list configured for the second channel by SIB1, where the second channel is used to carry Msg3; a fourth list corresponding to the default first channel; and a fifth list corresponding to the default second channel. In one possible embodiment, the use priority of the first list is higher than the use priority of the second list; the use priority of the second list is higher than the use priority of the third list; the use priority of the third list is higher than the use priority of the fourth list; the use priority of the first list is higher than the use priority of the fourth list; the use priority of the second list is higher than the use priority of the fourth list; and the use priority of the fourth list is higher than the use priority of the fifth list. Existing fields include at least one of the following: a TPC field, an MCS field, a TDRA field, and an FDRA field. The existing list includes at least one of the following: a TPC list, an MCS list, and a TDRA list.

[0264] In some embodiments, the existing list and / or the newly added list may be determined by at least one of the following methods: protocol specification; base station configuration. If the existing list and / or the newly added list are configured by the base station, the existing list and / or the newly added list are configured using at least one of the following signaling methods: SIB1; OSI; or RRC signaling carried by Msg4.

[0265] In some embodiments, the protocol or network equipment (such as a base station) can reuse existing lists to configure the number of retransmissions to the terminal device, such as TPC, TDRA, MCS, etc. lists, and further use corresponding fields in the DCI, such as TPC, TDRA, MCS, etc., to indicate the row index of the list to indicate the number of retransmissions. For example, a new column is added to the TDRA list to carry the number of retransmissions, and different rows can have different values. Optionally, taking the TDRA list as an example, the number of rows in the TDRA list can be increased. In this way, the number of DCI bits is also increased accordingly. For example, if the number of rows in the TDRA list is increased from 16 rows to 32 rows, the DCI bit overhead is increased from 4 bits to 5 bits. The TDRA list can be the TDRA list configured by Msg4RRC signaling, the TDRA list configured by SIB1, or the default TDRA list in the protocol. The priority used is the same as the legacy rule. Or, for example, a new column is added to the MCS list to carry the number of retransmissions, and different rows can have different values. Or, for example, a new column is added to the TPC list to carry the number of retransmissions, and different rows can have different values. Alternatively, at least part of the values ​​in the TPC list is reused, such as at least one of all negative values, zero values, and at least part of the positive values ​​in the list.

[0266] In some embodiments, when the terminal device supports first channel retransmission, or reports terminal capability indication, or initiates a first channel retransmission request, or reports auxiliary information, or the network device configures the first channel repetitionnumberlist / RSRP threshold, or the TDRAlist configured by the network device contains the repetitionnumber field, or the data retransmission function is explicitly enabled by the network device, or the DCI bearer bit indicates that the existing field is used for the first channel retransmission indication, the terminal device performs parsing based on the newly defined list; terminal devices other than the above situations can interpret the field based on the original meaning.

[0267] In some embodiments, a network device (such as a base station) may use a newly added bit or a reserved bit in the DCI to indicate the number of retransmissions to the terminal device. Optionally, the number of retransmissions may be indicated directly, or an index value for setting the number of retransmissions may be indicated, the index value being the index value of an existing list or the index value of a newly added list. The corresponding field of the first information may be multiplexed in an existing list, or the first information may be configured in a newly added list. In some embodiments, the newly added list and / or the existing list includes at least one of the following: the first list configured for the first channel by the RRC signaling carried by Msg4; the second list configured for the first channel by SIB1; the third list configured for the second channel by SIB1, wherein the second channel is used to carry Msg3; the fourth list corresponding to the default first channel; the fifth list corresponding to the default second channel. A possible embodiment is that the use priority of the first list is higher than the use priority of the second list; the use priority of the second list is higher than the use priority of the third list; the use priority of the third list is higher than the use priority of the fourth list; the use priority of the first list is higher than the use priority of the fourth list; the use priority of the second list is higher than the use priority of the fourth list; the use priority of the fourth list is higher than the use priority of the fifth list. The existing fields include at least one of the following: a TPC field, an MCS field, a TDRA field, and an FDRA field. The existing lists include at least one of the following: a TPC list, an MCS list, and a TDRA list.

[0268] In some embodiments, at least some bits in an existing field, newly added bits, or reserved bits can be used to indicate the index of an existing list or the index of a new list. The new list is defaulted in the protocol or configured by the base station. The existing list can be a repetition value list configured by the base station for Msg3, or a Msg3 default value list, or a newly added column indicating a repetition value field in a TPC list, TDRA list, or MCS list.

[0269] In some embodiments, at least part of the bits in the existing field, newly added bits, and at least one of the reserved bits can be used to directly indicate the number of repetitions using code points. For example, if the number of repetitions is 8, 3 bits "111" can be directly used to indicate 8 repetitions, or 4 bits "1000" can be used to indicate 8 repetitions, etc.

[0270] Step 202: The terminal device repeatedly transmits the first channel according to the first information.

[0271] Step 203: The network side repeatedly receives the first channel according to the first information.

[0272] In some embodiments, the terminal device repeatedly transmits the first channel according to the number of retransmissions in the first information, and the network device (such as a base station) repeatedly receives the first channel according to the number of retransmissions in the first information. The coverage can be increased by repeated transmission, that is, the same data is sent repeatedly to improve the transmission performance, thereby enhancing the coverage of Msg5 and subsequent PUSCH, improving the performance of data transmission, and improving the spectrum efficiency.

[0273] This embodiment provides a channel blind retransmission solution. The network device indicates first information to the terminal device, and the terminal device can retransmit the first channel based on the first information, thereby enhancing the coverage of the first channel and improving the performance of data transmission.

[0274] To illustrate the specific execution process of the terminal device, Figure 5 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. When applied to the terminal device side, the method may include the following steps.

[0275] Step 301: The terminal device sends first information to the network device.

[0276] The first information may be the number of retransmissions (repetitions) of the first channel, indicating blind retransmission of the first channel. The first channel is used to carry at least one of the following messages: RRCSetupComplete; RRCResumeComplete; RRCReestablishmentComplete; core network connection establishment signaling; NAS layer signaling; security messages; and terminal capability signaling. Transmission of the first channel may occur after the terminal receives Msg4 sent by the network device and before the terminal receives RRC reconfiguration signaling sent by the network device.

[0277] In some embodiments, before executing the embodiments of the present disclosure, the terminal device may first determine the first information. When determining the first information:

[0278] In some embodiments, the terminal device may also receive the second information sent by the base station, or when the second information is not received, the default reference signal received power RSRP threshold is determined as the second information. The terminal device further determines the first information based on the second information and the information correspondence. In some embodiments, the second information may be an RSRP threshold, and the information correspondence may be a correspondence between the RSRP threshold and the number of retransmissions, that is, different RSRP thresholds correspond to different numbers of retransmissions. The RSRP threshold and the number of repetitions and the correspondence between the two can be configured by the base station through system message 1 (System information block 1, SIB1) / other system messages (Other system information, OSI) / Radio Resource Control (Radio Resource Control, RRC) (such as RRC signaling carried in Msg4), that is, the terminal device receives the first configuration information and determines the information correspondence according to the first configuration information; alternatively, the correspondence between the RSRP threshold and the number of retransmissions can also be specified in the protocol, which is not specifically limited here.

[0279] In some embodiments, the terminal device may determine a default repetition number of the first channel as the first information.

[0280] In some embodiments, only when the network device is configured with the RSRP threshold and / or the number of retransmissions, that is, the network device has been upgraded to R19 and has the ability to receive the number of retransmissions and to repeatedly transmit Msg5 and / or subsequent PUSCH data with the terminal device based on the number of retransmissions, the terminal device will make a judgment on the number of retransmissions and report the number of retransmissions. And / or, the base station can configure the display enable signaling of the number of retransmissions corresponding to the first channel through SIB1 / OSI / RRC, that is, the terminal device receives the display enable signaling, and the display enable signaling is used to instruct the terminal to determine the first information, and / or instruct the terminal to send the first information, and / or instruct the terminal to enable blind retransmission of the first channel. Only when the base station displays that the repetition transmission of the first channel is enabled, the terminal will report the number of retransmissions of the first channel, otherwise, the number of retransmissions of the first channel will not be determined or reported. In addition, a possible embodiment is that if the RSRP threshold and / or the number of retransmissions are not configured, and the base station displays that the number of retransmissions of Msg5 and / or subsequent PUSCH is enabled, the terminal determines the number of first channel retransmissions based on the default RSRP threshold and / or the default repetition value, and reports the number of first channel retransmissions.

[0281] For the embodiments of the present disclosure, when the terminal device sends the first information to the network device, the terminal device can send the first information to the network device (such as a base station) through any one of Msg1, Msg3, and Msg5. The terminal device and the network device both repeatedly transmit the first channel this number of times, thereby enhancing the coverage of Msg5 and subsequent PUSCH, improving the performance of data transmission, and improving spectrum efficiency.

[0282] The terminal device may send the first information in at least one of the following ways: implicitly sending the first information through the physical random access channel PRACH resources, wherein different first information corresponds to different PRACH resources; sending the first information through the demodulation reference signal DMRS of Msg3, wherein different first information corresponds to different DMRS, and the specific corresponding rules may be agreed upon by the terminal device and the network device, or may be configured to the terminal device by the network device, or the relationship between the DMRS resources and the number of retransmissions may also be determined through the combined effect of the protocol provisions and the network device configuration, which is not specifically limited here; using the newly generated wireless network temporary identifier RNTI to scramble the PUSCH codeword of Msg3 to send the first information, wherein different first information corresponds to different RNTIs, and the rules for generating a new RNTI may be defined in the protocol; indicating the first information through the reserved bits of the MAC subheader corresponding to the media access control MAC SDU or MAC CE of Msg3 or Msg5; indicating the first information through the reserved bits of the MAC subheader corresponding to the media access control MAC SDU or MAC The newly generated logical channel identifier LCID in the MAC subheader corresponding to the CE indicates the first information, where different LCIDs are used to indicate different first information; the new or original MAC CE in Msg3 or Msg5 is used to indicate the first information; the reserved bit or newly added bit in the RRCResumeRequest, RRCSetupRequest, or RRCReestablishmentRequest corresponding to Msg3 is used to indicate the first information; the reserved bit or newly added bit in the RRCResumeComplete, RRCSetupComplete, or RRCReestablishmentComplete corresponding to Msg5 is used to indicate the first information; the new RRC signaling carried in the Msg3 or Msg5 MAC PDU is used to indicate the first information; after the Msg5 MAC PDU is handed over to the physical layer, the first information is indicated by the physical layer bit attached to the payload. The specific implementation process can be found in the relevant description in step 102 of the embodiment and will not be repeated here.

[0283] In some embodiments, when indicating the first information to the base station through bits, the index corresponding to the first information (the index in the repetition times list) may also be indicated to the base station, thereby saving bit overhead.

[0284] This embodiment provides a communication processing method, whereby a terminal device may send a first message to a network device, and use the first message to instruct the network device to perform blind retransmission of a first channel. By blindly retransmitting the first channel, coverage enhancement of Msg5 and subsequent PUSCHs may be achieved.

[0285] To illustrate the specific execution process of the terminal device, Figure 6 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. When applied to the terminal device side, the method may include the following steps.

[0286] Step 401: The terminal device receives first information sent by the network device.

[0287] Among them, the first information may be the number of retransmissions (repetition times) of the first channel, which is used to indicate blind retransmission of the first channel. The first channel is used to carry at least one of the following messages: RRCSetupComplete; RRCResumeComplete; RRCReestablishmentComplete; core network connection establishment signaling; NAS layer signaling; security messages; terminal capability signaling.

[0288] In some embodiments, before executing the embodiments of the present disclosure, the network device (such as a base station) may first determine the first information, and after determining the first information, may send the first information to the terminal device. When the network device sends the first information, its specific implementation process can refer to the relevant description in step 201 of the embodiment, which will not be repeated here. In some embodiments, the terminal device may receive the first information (i.e., the number of retransmissions) sent by the base station in a semi-static manner, and the terminal device may determine whether to perform blind retransmission of the first channel based on the number of retransmissions through RSRP threshold judgment; or, the terminal device may receive the first information sent by the base station in a dynamic manner after performing capability reporting / auxiliary information reporting / first channel blind retransmission request, and specifically may receive the first information indicated by the downlink control information (Downlink Control Information, DCI) of the physical uplink shared channel (PUSCH) scheduled by the network device.

[0289] In some embodiments, when the terminal device receives the DCI indicating the number of retransmissions of the PUSCH scheduled by the network device, specifically, at least one of the following methods may be used:

[0290] In some embodiments, a terminal device may receive first information indicated by an existing field in a base station multiplexing DCI. For example, the lower or upper bits of any of the above fields may be used to indicate the number of retransmissions. The existing fields may include at least one of the following: a TPC field, an MCS field, a TDRA field, and an FDRA field.

[0291] In some embodiments, a terminal device may receive an index value of first information indicated by an existing field in a base station-reused DCI. This index value is the index value of an existing list or the index value of a newly added list. The corresponding field of the first information may be reused in the existing list, or the first information may be configured in the newly added list. In some embodiments, the newly added list and / or existing list include at least one of the following: a first list configured for the first channel in the RRC signaling carried by Msg4; a second list configured for the first channel by SIB1; a third list configured for the second channel by SIB1, where the second channel is used to carry Msg3; a fourth list corresponding to the default first channel; and a fifth list corresponding to the default second channel. In one possible embodiment, the first list has a higher priority than the second list; the second list has a higher priority than the third list; the third list has a higher priority than the fourth list; the first list has a higher priority than the fourth list; the second list has a higher priority than the fourth list; and the fourth list has a higher priority than the fifth list. Existing fields include at least one of the following: a TPC field, an MCS field, a TDRA field, or an FDRA field. Existing lists include at least one of the following: a TPC list, an MCS list, and a TDRA list.

[0292] In some embodiments, the existing list and / or the newly added list may be determined by at least one of the following methods: protocol specification; base station configuration. If the existing list and / or the newly added list are configured by the base station, the existing list and / or the newly added list are configured using at least one of the following signaling methods: SIB1; OSI; or RRC signaling carried by Msg4.

[0293] In some embodiments, a terminal device may receive first information indicated by a base station using a newly added bit or a reserved bit in a DCI. Optionally, the base station may use the newly added bit or the reserved bit in the DCI to directly indicate the number of retransmissions, or may indicate an index value for setting the number of retransmissions, where the index value is an index value of an existing list or an index value of a newly added list. The corresponding field of the first information may be multiplexed in an existing list, or the first information may be configured in a newly added list. In some embodiments, the newly added list and / or the existing list include at least one of the following: a first list configured for the first channel by RRC signaling carried by Msg4; a second list configured for the first channel by SIB1; a third list configured for the second channel by SIB1, where the second channel is used to carry Msg3; a fourth list corresponding to the default first channel; and a fifth list corresponding to the default second channel. In one possible embodiment, the use priority of the first list is higher than the use priority of the second list; the use priority of the second list is higher than the use priority of the third list; the use priority of the third list is higher than the use priority of the fourth list; the use priority of the first list is higher than the use priority of the fourth list; the use priority of the second list is higher than the use priority of the fourth list; and the use priority of the fourth list is higher than the use priority of the fifth list. The existing fields include at least one of the following: a TPC field, an MCS field, a TDRA field, and an FDRA field. The existing lists include at least one of the following: a TPC list, an MCS list, and a TDRA list.

[0294] Step 402: Perform blind retransmission on the first channel according to the first information.

[0295] In some embodiments, after receiving the first information sent by the network device (i.e., the number of retransmissions), the terminal device can repeatedly transmit Msg5 and / or subsequent PUSCH channels according to the number of retransmissions. The coverage can be increased by repeated transmission, that is, the same data is sent repeatedly multiple times to improve the transmission performance, thereby enhancing the coverage of Msg5 and subsequent PUSCH, improving the performance of data transmission, and improving spectrum efficiency.

[0296] This embodiment provides a communication processing method, where a network device may send a first message to a terminal device, and use the first message to instruct the terminal device to perform blind retransmission of a first channel. By blindly retransmitting the first channel, coverage enhancement of Msg5 and subsequent PUSCHs may be achieved.

[0297] To illustrate the specific execution process of the network device, Figure 7 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. When applied to the network device side, the method may include the following steps.

[0298] Step 501: A network device receives first information sent by a terminal device.

[0299] The first information may be the number of retransmissions (repetition count) of the first channel, indicating blind retransmission of the first channel. Blind retransmission can enhance coverage of Msg5 and subsequent PUSCHs. The first channel is used to carry at least one of the following messages: RRCSetupComplete; RRCResumeComplete; RRCReestablishmentComplete; core network connection establishment signaling; NAS layer signaling; security messages; and terminal capability signaling. Transmission of the first channel may occur after the terminal receives Msg4 sent by the network device and before the terminal receives RRC reconfiguration signaling sent by the network device.

[0300] In some embodiments, before executing the embodiments of the present disclosure, the terminal device may first determine the first information. When determining the first information:

[0301] In some embodiments, a network device (such as a base station) may send a second information to a terminal device, and the second information is used by the terminal device to determine the first information corresponding to the second information according to the information correspondence relationship. The second information may be an RSRP threshold, and the information correspondence relationship may be the correspondence between the RSRP threshold and the number of retransmissions, that is, different RSRP thresholds correspond to different numbers of retransmissions. The RSRP threshold and the number of repetitions and the correspondence between the two can be configured by the base station through system message 1 (System information block 1, SIB1) / other system messages (Other system information, OSI) / Radio Resource Control (Radio Resource Control, RRC) (such as RRC signaling carried in Msg4), etc., that is, the network device may send a first configuration information to the terminal device, and the first configuration information is used to indicate the information correspondence relationship, and the information correspondence relationship is different first information corresponding to different second information. After receiving the first configuration information, the terminal device can determine the information correspondence relationship based on the first configuration information.

[0302] In some embodiments, the terminal device may determine a default repetition number of the first channel as the first information.

[0303] In some embodiments, only when the network device is configured with the RSRP threshold and / or the number of retransmissions, that is, the network device has been upgraded to R19 and has the ability to receive the number of retransmissions and to repeatedly transmit Msg5 and / or subsequent PUSCH data with the terminal device based on the number of retransmissions, the terminal device will make a judgment on the number of retransmissions and report the number of retransmissions. And / or, the base station can configure the display enable signaling of the number of retransmissions corresponding to the first channel through SIB1 / OSI / RRC, that is, send a display enable signaling to the terminal device, the display enable signaling is used to instruct the terminal device to determine the first information, and / or instruct the terminal device to send the first information, and / or instruct the terminal device to enable blind retransmission of the first channel. Only when the base station displays that the repetition transmission of the first channel is enabled, the terminal will report the number of retransmissions of the first channel, otherwise, the number of retransmissions of the first channel will not be determined and reported.

[0304] In some embodiments, when the terminal device sends the first information to the network device, the terminal device may send the first information to the network device (such as a base station) through any one of Msg1, Msg3, and Msg5. The terminal device and the network device both repeat the transmission of the first channel at that number of times, thereby enhancing the coverage of Msg5 and subsequent PUSCHs, improving the performance of data transmission, and improving spectrum efficiency. The specific implementation process can be found in the relevant description in step 102 of the embodiment and will not be repeated here. For this embodiment, the network device can receive the first information sent by the terminal device in at least one of the following ways: receiving the first information implicitly sent by the terminal device through the physical random access channel PRACH resource, wherein different first information corresponds to different PRACH resources; receiving the first information sent by the terminal device through the demodulation reference signal DMRS of Msg3, wherein different first information corresponds to different DMRS, and the specific corresponding rules can be agreed upon by the terminal device and the network device, or can be configured to the terminal device by the network device, or the relationship between the DMRS resource and the number of retransmissions can also be determined through the joint action of the protocol provisions and the network device configuration, which is not specifically limited here; receiving the first information sent by the terminal device by scrambling the PUSCH codeword of Msg3 using the newly generated wireless network temporary identifier RNTI, wherein different first information corresponds to different RNTIs, and the rules for generating a new RNTI can be defined in the protocol; receiving the first information indicated by the reserved bit of the MAC subheader corresponding to the media access control MAC SDU or MAC CE corresponding to Msg3 or Msg5; receiving the first information indicated by the reserved bit of the MAC subheader corresponding to the media access control MAC SDU or MAC The first information indicated by the newly generated logical channel identifier LCID in the MAC subheader corresponding to the CE, wherein different LCIDs are used to indicate different first information; the first information indicated by the new or original MAC CE in Msg3 or Msg5 is used by the receiving terminal device; the first information indicated by the reserved bit or the newly added bit in Msg3 corresponding to RRCResumeRequest, RRCSetupRequest, or RRCReestablishmentRequest is used by the receiving terminal device; the first information indicated by the reserved bit or the newly added bit in Msg5 corresponding to RRCResumeComplete, RRCSetupComplete, or RRCReestablishmentComplete is used by the receiving terminal device; the first information indicated by the new RRC signaling carried in the Msg3 or Msg5 MAC PDU is used by the receiving terminal device; the first information indicated by the physical layer bit attached to the payload after the Msg5 MAC PDU is handed over to the physical layer.

[0305] In some embodiments, when the terminal device indicates the first information to the base station through bits, the network device can also receive the index corresponding to the first information (the index in the repetition times list), thereby saving bit overhead.

[0306] Step 502: Perform blind retransmission on the first channel according to the first information.

[0307] In some embodiments, after the network device receives the first information (i.e., the number of retransmissions) sent by the terminal device, the terminal device can repeatedly transmit the first channel with the number of retransmissions in the first information, and the network device (such as a base station) can repeatedly receive the first channel with the number of retransmissions in the first information. The coverage can be increased by repeated transmission, that is, the same data is sent repeatedly multiple times to improve the transmission performance, thereby enhancing the coverage of Msg5 and subsequent PUSCH, improving the performance of data transmission, and improving the spectrum efficiency.

[0308] This embodiment provides a communication processing method, where a terminal device may send first information to a network device, and use the first information to instruct the network device to perform blind retransmission of a first channel. By blind retransmission of the first channel, coverage enhancement of the first channel may be achieved.

[0309] To illustrate the specific execution process of the network device, Figure 8 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. When applied to the network device side, the method may include the following steps.

[0310] Step 601: The network device sends first information to the terminal device.

[0311] The first information may be the number of retransmissions (repetitions) of the first channel, indicating blind retransmission of the first channel. The first channel is used to carry at least one of the following messages: RRCSetupComplete; RRCResumeComplete; RRCReestablishmentComplete; core network connection establishment signaling; NAS layer signaling; security messages; and terminal capability signaling. Transmission of the first channel may occur after the terminal receives Msg4 sent by the network device and before the terminal receives RRC reconfiguration signaling sent by the network device.

[0312] In some embodiments, before executing the embodiments of the present disclosure, the network device (such as a base station) may first determine the first information, and after determining the first information, may send the first information to the terminal device. When the network device sends the first information, its specific implementation process can refer to the relevant description in step 201 of the embodiment, which will not be repeated here. In some embodiments, when the network device indicates the number of retransmissions to the terminal device, it may indicate in a semi-static manner, that is, indicate a number of retransmissions. In some embodiments, the network device (such as a base station) may directly indicate a number of retransmissions through SIB1 / OSI, and the terminal device with this capability directly performs PUSCH transmission based on this number of retransmissions. Optionally, the terminal device with this capability may determine whether to repeat the transmission of the first channel based on the number of retransmissions after receiving the number of retransmissions indicated by the network device through the RSRP threshold judgment. In some embodiments, the network device (such as a base station) may configure a number of retransmissions based on the terminal capability report and / or the auxiliary information report and / or the first channel blind retransmission request through the RRC signaling carried in Msg4, and the terminal transmits the first channel based on the number of retransmissions.

[0313] As a possible implementation, the RRC signaling of both SIB1 and Msg4 can configure the number of repeated transmissions for the first channel. If the RRC signaling of both SIB1 and Msg4 configures the number of repeated transmissions for the first channel, a usage priority can be defined. One possible implementation is: the usage priority configured by the Msg4 RRC signaling is higher than the usage priority configured by SIB1. When the RRC signaling of neither SIB1 nor Msg4 configures the number of repeated transmissions, the first channel repeated transmission number configured by Msg3 or the default first channel repeated transmission number can be used; the optional usage priority configured by Msg3 c must be higher than the default usage priority. For example, the default number of repeated transmissions of the first channel is 1; or the default number of repeated transmissions of the first channel is not 1, when the terminal supports Msg5 repetition, or reports the terminal capability indication, or initiates a repetition request, or reports auxiliary information, or configures the repetition value list / RSRP threshold, or the Msg5 repetition function is displayed by the base station to enable the first channel repetition, or the DCI bearer bit indicates that the existing field is used for repetition indication, and the repetition number is not configured, the default number of repeated transmissions of the first channel can be used.

[0314] In some embodiments, when the network device indicates the number of retransmissions to the terminal device, it may indicate in a dynamic manner, that is, dynamically indicate multiple retransmission times. Optionally, the network device will indicate the number of retransmissions (which may include the case where the indication is 1) only after the terminal device has performed capability reporting / auxiliary information reporting / first channel blind retransmission request. The network device may indicate the first information to the terminal device by scheduling downlink control information (Downlink Control Information, DCI) of the Physical Uplink Shared Channel (PUSCH).

[0315] In some embodiments, when the network device schedules the number of retransmissions indicated by the DCI of the PUSCH, specifically, at least one of the following methods may be used:

[0316] In some embodiments, the network device may reuse existing fields in the DCI to indicate the first information to the terminal device, such as using the lower or upper bits of any of the above fields to indicate the number of retransmissions. The existing fields include at least one of the following: a TPC field, an MCS field, a TDRA field, and a FDRA field.

[0317] In some embodiments, the network device reuses existing fields in the DCI to indicate to the network device an index value of the first information. This index value is the index value of an existing list or the index value of a newly added list. The corresponding field of the first information may be reused in the existing list, or the first information may be configured in the newly added list. In some embodiments, the newly added list and / or the existing list include at least one of the following: a first list configured for the first channel in the RRC signaling carried by Msg4; a second list configured for the first channel by SIB1; a third list configured for the second channel by SIB1, where the second channel is used to carry Msg3; a fourth list corresponding to the default first channel; and a fifth list corresponding to the default second channel. In one possible embodiment, the first list has a higher priority than the second list; the second list has a higher priority than the third list; the third list has a higher priority than the fourth list; the first list has a higher priority than the fourth list; the second list has a higher priority than the fourth list; and the fourth list has a higher priority than the fifth list. Existing fields include at least one of the following: a TPC field, an MCS field, a TDRA field, or an FDRA field. Existing lists include at least one of the following: a TPC list, an MCS list, and a TDRA list.

[0318] In some embodiments, the existing list and / or the newly added list may be determined by at least one of the following methods: protocol specification; base station configuration. If the existing list and / or the newly added list are configured by the base station, the existing list and / or the newly added list are configured using at least one of the following signaling methods: SIB1; OSI; or RRC signaling carried by Msg4.

[0319] In some embodiments, a terminal device may receive first information indicated by a base station using a newly added bit or a reserved bit in a DCI. Optionally, the base station may use the newly added bit or the reserved bit in the DCI to directly indicate the number of retransmissions, or may indicate an index value for setting the number of retransmissions, where the index value is an index value of an existing list or an index value of a newly added list. The corresponding field of the first information may be multiplexed in an existing list, or the first information may be configured in a newly added list. In some embodiments, the newly added list and / or the existing list include at least one of the following: a first list configured for the first channel by RRC signaling carried by Msg4; a second list configured for the first channel by SIB1; a third list configured for the second channel by SIB1, where the second channel is used to carry Msg3; a fourth list corresponding to the default first channel; and a fifth list corresponding to the default second channel. In one possible embodiment, the use priority of the first list is higher than the use priority of the second list; the use priority of the second list is higher than the use priority of the third list; the use priority of the third list is higher than the use priority of the fourth list; the use priority of the first list is higher than the use priority of the fourth list; the use priority of the second list is higher than the use priority of the fourth list; and the use priority of the fourth list is higher than the use priority of the fifth list. The existing fields include at least one of the following: a TPC field, an MCS field, a TDRA field, and an FDRA field. The existing lists include at least one of the following: a TPC list, an MCS list, and a TDRA list.

[0320] This embodiment provides a communication processing method, where a network device may send a first message to a terminal device, and use the first message to instruct the terminal device to perform blind retransmission of a first channel. By blindly retransmitting the first channel, coverage enhancement of Msg5 and subsequent PUSCHs may be achieved.

Available media may be magnetic media (eg, floppy disks, hard disks, tapes), optical media (eg, high-density digital video discs (DVDs)), or semiconductor media (eg, solid state disks (SSDs)).

[0475] This disclosure proposes a communication processing method and apparatus that can provide a solution for determining the number of retransmissions on a first channel. By performing retransmission processing on the first channel based on the number of retransmissions, coverage enhancement for Msg5 and subsequent PUSCHs can be achieved, thereby improving data transmission performance.

[0476] Based on this disclosure, examples of embodiments of this solution are as follows:

[0477] Consider at least one of the following methods for determining the number of repetitions (i.e., the number of retransmissions):

[0478] Direction 1: The terminal determines the number of repetitions based on RSRP threshold measurement and reports this number to the gNB via Msg1 / 3 / 5. The gNB and the terminal use this number for Msg5 and / or subsequent PUSCH repetition transmissions.

[0479] Point 1: Different RSRP thresholds can correspond to different transmission times. The RSRP threshold and the number of repetitions, as well as the corresponding relationship between the two, can be configured by the base station through SIB1 / OSI / RRC (such as Msg4), etc., or can be specified in the protocol.

[0480] Point 2: The terminal can indicate the number of repetitions determined by itself to the base station in one of the following ways:

[0481] Opt.1: Implicit reporting via one or more separate PRACH resource groups configured by the base station, which can be distinguished by at least one or more of the following: time domain, frequency domain, code domain

[0482] Opt.2: Distinguish through Msg3 DMRS

[0483] Opt. 3: Based on the TC-RNTI indicated by the RAR, the terminal generates a new RNTI, scrambles the Msg3 PUSCH codeword based on the new RNTI, and reports the repetition count based on this RNTI. The rules for generating the new RNTI are defined in the protocol.

[0484] Opt. 4: Use the reserved bits in the Msg3 / 5 MAC subheader, new LCID(s) (different LCIDs are associated with different repetition times), using new or reusing legacy MAC CEs, using the reserved bits in RRCResumeRequest / Complete, RRCSetupRequest / Complete, or RRCReestablishmentRequest / Complete, or adding new bits, or designing a new RRC signaling bearer for reporting in the Msg5 MAC PDU. Alternatively, after the MAC PDU is handed over to the physical layer, append a physical layer bit to the payload for indication. If using bits for explicit indication, the index in the repetition count list can also be indicated to save bit overhead.

[0485] Key Point 3: The terminal will only determine and report the number of repetitions if the base station has configured the RSRP threshold and / or repetition number. Alternatively, the base station can configure Msg5 and subsequent PUSCH repetition enable signaling via SIB1 / OSI / RRC. Based on this, if the RSRP threshold and / or repetition number are not configured, and the base station indicates that repetition is enabled in Msg5 and / or subsequent PUSCH, the terminal will determine the repetition number based on the default RSRP threshold and / or default repetition number values ​​and report the repetition number.

[0486] Direction 2: The number of repetitions is configured and / or indicated by the base station.

[0487] In method 1, the number of repetitions is indicated semi-statically:

[0488] Opt. 1: The gNB directly indicates a repetition count through SIB1 / OSI. UEs with this capability use this count for PUSCH transmission.

[0489] Optionally, a terminal with this capability determines whether to perform Msg5 and / or subsequent PUSCH transmission based on the number of repetitions after judging the RSRP threshold.

[0490] Opt. 2: Based on the terminal's capability report and / or auxiliary information report, the base station configures a repetition count through RRC signaling carried in Msg4. The terminal transmits Msg5 and / or subsequent PUSCH based on this repetition count.

[0491] Mode 2: The number of repetitions is indicated dynamically. Optionally, the base station indicates the number of repetitions only after the terminal reports capability / auxiliary information / Msg5 repetition request (optional, including the case where the indication is 1):

[0492] The number of repetitions is indicated in the DCI for scheduling the PUSCH. Specifically, there can be at least one of the following methods:

[0493] Opt.1: Reuse existing fields such as TPC, MCS, TDRA, FDRA and other fields for indication. For example, use the lower bits or higher bits of any of the above fields to indicate the number of repetitions. The number of repetitions can be indicated directly, or the index of the repetition number list can be indicated. The list can be configured by the RRC signaling in SIB1 or Msg4. Optionally, if not configured, use the Msg3 configured value list or the default value list; the optional Msg3 configured value list has a higher priority than the default value list. In addition, one possible way is that the RRC signaling in SIB1 and Msg4 can both configure the repetition value list. If the RRC signaling of SIB1 and Msg4 are both configured with the Msg5 repetition value list, define the priority of use. One possible way is: the priority of use of the Msg4RRC configured value list is greater than the priority of use of the value list configured in SIB1. Optionally, the value list can contain the number 1.

[0494] When the terminal supports Msg5 repetition, or reports the terminal capability indication, or initiates a repetition request, or reports auxiliary information, or configures the repetition value list / RSRP threshold, or the Msg5 repetition function is explicitly enabled by the base station, or the DCI bearer bit indicates that the existing field is used for repetition indication, the terminal interprets the field based on the new definition; in cases other than the above, legacy terminals or R19 terminals interpret the field based on the original meaning.

[0495] Opt.2: Reuse existing tables, such as TPC, TDRA, and MCS, and further use the corresponding field in the DCI to indicate the row index of the table to indicate the number of repetitions.

[0496] For example, a new column is added to the TDRA table to carry the number of repetitions, with different values ​​in different rows. Optionally, the number of rows in the TDRA table can be increased. In this case, the number of DCI bits increases from 16 to 32, reducing the DCI bit overhead from 4 bits to 5 bits. The TDRA table can be the TDRA table configured with Msg4RRC signaling, the TDRA table configured with SIB1, or the default TDRA table. The priority used is the same as the legacy rule.

[0497] Or for example, a new column is added to the MCS table to carry the number of repetitions, and different rows can have different values.

[0498] Alternatively, for example, a new column can be added to the TPC table to carry the number of repetitions, with different rows having different values. Alternatively, at least some values ​​in the TPC table can be reused, such as all negative values, zero values, and at least some positive values.

[0499] When the terminal supports Msg5 repetition, or reports the terminal capability indication, or initiates a repetition request, or reports auxiliary information, or the gNB configures the repetition value list / RSRP threshold, or the Msg5 repetition function is explicitly enabled by the base station, or the DCI bearer bit indicates that the existing table is used for repetition indication, the terminal parses based on the newly defined table; otherwise, in cases other than the above, legacy terminals or R19 terminals parse the above table based on the original meaning.

[0500] Opt.3: Use a new bit or a reserve bit to indicate the number of repetitions. The specific indication method can directly indicate the number of repetitions, or it can indicate the index of the repetition number list, which can be configured by the RRC signaling in SIB1 or Msg4. Optionally, if not configured, use the Msg3 configured value list or the default value list; the optional Msg3 configured value list has a higher priority than the default value list. In addition, one possible way is that the RRC signaling in SIB1 and Msg4 can both configure the repetition value list. If the RRC signaling of SIB1 and Msg4 are both configured with the Msg5 repetition value list, define the priority of use. One possible way is: the priority of use of the Msg4RRC configured value list is greater than the priority of use of the value list configured by SIB1. Optionally, the value list can contain the number 1.

[0501] In summary, the present disclosure has the following beneficial effects: proposing a method for indicating the number of Msg5 and subsequent PUSCH repetitions, which can enhance the coverage of Msg5 and subsequent PUSCH, improve data transmission performance, and enhance spectrum efficiency.
