[0174] The communication processing method and device provided by the embodiments of the present disclosure provide a terminal capability and / or auxiliary information reporting mechanism, so that the base station can configure a reasonable retransmission number value for the terminal to ensure the coverage enhancement effect of Msg5 and subsequent PUSCH channels.

[0175] 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:

[0176] Step 101: The terminal device sends the first information.

[0177] In some embodiments, the first information may be used by the network device to determine the configuration and / or instruct the terminal to blindly retransmit a first channel, where the first channel is 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. 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.

[0178] 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 terminal capability signaling and / or auxiliary information. The terminal capability signaling is used to indicate the terminal capability information of the blind retransmission of the first channel, and the auxiliary information is used by the network device to determine the configuration and / or instruct the terminal to blindly retransmit the first channel.

In the case where the RSRP threshold and / or RSRP quantization value are configured by a network device, the RSRP threshold and / or RSRP quantization value are configured by at least one of the following signaling: SIB1; OSI; RRC signaling carried by Msg4. 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 terminal capability signaling and / or auxiliary information as an example, but does not constitute a specific limitation. The terminal device can determine the terminal capability information and / or auxiliary information, and send the terminal capability signaling and / or auxiliary information to the network device (such as a base station), so that the network device can determine the configuration and / or instruct the terminal to blindly retransmit the first channel to ensure the coverage enhancement effect on Msg5 and subsequent PUSCH channels.

[0179] In some embodiments, in some embodiments, the terminal device may send a first message to a network device (such as a base station) through any one of Msg1, Msg3, and Msg5. After receiving the first message, the network device may determine whether the terminal device supports repeated transmission of Msg5 based on the first information. When judging that the terminal device supports repeated transmission of Msg5, a reasonable retransmission number value is configured for the terminal device to ensure the coverage enhancement effect of Msg5 and subsequent PUSCH channels.

[0180] When the terminal device sends the first information to the network device:

[0181] In some embodiments, the terminal device may implicitly report the first information through one or more separate groups of physical random access channel (PRACH) resources configured by the network device. Accordingly, the terminal device may receive PRACH resources configured by the network device, and the PRACH resources are used to indicate the first information. Different first information may correspond to different PRACH resource groups, and different first information 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, by adding a Msg5-repetition-r19 field in the RRC IE FeatureCombination-r17 configured by the network device to configure a separate PRACH resource for repeated transmission of the first channel.

[0182] In some embodiments, the terminal device may send the first message to the network device based on Msg3:

[0183] As a possible implementation method, the demodulation reference signal (DMRS) of Msg3 can be used to distinguish (such as distinguishing different time domains, frequency domains, and code domains, etc.) the first information. Different first information can correspond to different DMRS. 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 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.

[0184] As a possible implementation method, the terminal device can indicate the first information through a new logical channel identifier (LCID) in the MAC subheader corresponding to the media access control MAC SDU or MAC CE of Msg3, where different LCIDs are used to indicate different first information.

[0185] As a possible implementation method, the terminal device can indicate the first information through the reserved bit of the MAC subheader corresponding to the Media Access Control (MAC) service data unit (SDU) or MAC control element (MAC CE) of Msg3.

[0186] As a possible implementation method, the terminal device may use a new or reused existing MAC CE in Msg3 to indicate the first information.

[0187] As a possible implementation method, the terminal device can use the reserved bit in Msg3 corresponding to carry the message RRCResumeRequest, RRCSetupRequest, or RRCReestablishmentRequest, or add a new bit to indicate the first information.

[0188] As a possible implementation method, the terminal device may use new RRC signaling carried in the Msg3 MAC PDU to indicate the first information.

[0189] As a possible implementation manner, the terminal device may indicate the first information through a physical layer bit attached to the payload after handing over the Msg3 MAC PDU to the physical layer.

[0190] In some embodiments, the terminal device may send the first message to the network device based on Msg5:

[0191] As a possible implementation method, the demodulation reference signal (DMRS) of Msg5 can be used to distinguish (such as distinguishing different time domains, frequency domains, and code domains, etc.) the first information. Different first information can correspond to different DMRS. 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 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.

[0192] As a possible implementation method, the terminal device can indicate the first information through the newly generated logical channel identifier (LCID) in the MAC subheader corresponding to the media access control MAC SDU or MAC CE of Msg5, where different LCIDs are used to indicate different first information.

[0193] As a possible implementation method, the terminal device can indicate the first information through the reserved bit of the MAC subheader corresponding to the Media Access Control (MAC) service data unit (SDU) or MAC control element (MAC CE) of Msg5.

[0194] As a possible implementation manner, the terminal device may use the new or original MAC CE in Msg5 to indicate the first information.

[0195] As a possible implementation method, the terminal device can use the reserved bit in Msg5 to carry the message RRCsetupComplete, RRCResumeComplete or RRCReestablishmentComplete, or add a new bit to indicate the first information.

[0196] As a possible implementation method, the terminal device may use new RRC signaling carried in the Msg5 MAC PDU to indicate the first information.

[0197] As a possible implementation method, the terminal device may indicate the first information through a physical layer bit attached to the payload after handing over the Msg5 MAC PDU to the physical layer.

[0198] In some embodiments, when the terminal device sends the first information to the network device, if the indication is displayed through bits, the index value configured in the auxiliary information corresponding list may also be indicated to the network device, thereby saving bit overhead. The auxiliary information list may include an RSRP threshold list, an RSRP quantization value list, etc. For example, when the terminal device sends the RSRP threshold in the auxiliary information to the network device, the RSRP threshold list configured by the network device may be {2, 4, 8}, and the index value configured by the terminal device may be 0, 1, 2, where the index value 0 corresponds to 2 in the RSRP threshold list, the index value 1 corresponds to 4 in the RSRP threshold list, and the index value 2 corresponds to 8 in the RSRP threshold list.

[0199] Among them, the auxiliary information list can be configured by RRC signaling in SIB1 or Msg4. Optionally, if not configured, the auxiliary information list configured by Msg3 or the default auxiliary information list is used. Optionally, the use priority of the auxiliary information list configured by Msg3 is higher than the default auxiliary information list. In addition, a possible implementation method is that the RRC signaling in SIB1 and Msg4 can both configure the auxiliary information list. If the RRC signaling of SIB1 and Msg4 are both configured with auxiliary information lists, the use priority can be defined. One possible way is that the use priority of the auxiliary information list configured by Msg4RRC is higher than the auxiliary information list configured by SIB1RRC. In some embodiments, the auxiliary information list is configured by at least one of the following methods: 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; the fifth list corresponding to the default second channel. The usage priority of the first list is higher than the usage priority of the second list; the usage priority of the second list is higher than the usage priority of the third list; the usage priority of the third list is higher than the usage priority of the fourth list; the usage priority of the first list is higher than the usage priority of the fourth list; the usage priority of the second list is higher than the usage priority of the fourth list; the usage priority of the fourth list is higher than the usage priority of the fifth list.

[0200] In some embodiments, for the case where the above-mentioned terminal device indicates the first information based on the Msg1 resource, the terminal device can directly determine whether the current network device supports blind retransmission of the first channel by whether the network device is configured with a separate PRACH resource; for the case where the above-mentioned terminal device sends the first information based on Msg1 and / or Msg3 and / or sends the first information based on Msg5, the network device can generate display enable signaling through SIB1 or RRC reconfiguration signaling, and the terminal device can send the first information based on Msg3 and / or Msg5 only after receiving the display enable signaling sent by the network device, wherein the display enable signaling is used to indicate that the network device supports blind retransmission of the first channel; or, the terminal device can determine whether the current network has enabled blind retransmission of the first channel by whether the network device is configured with an RSRP threshold / RSRP quantization value.

[0201] Step 102: The network device determines to configure and / or instructs the terminal device to blindly retransmit the first channel according to the first information.

[0202] In some embodiments, when the first information is terminal capability signaling, the network device may directly determine whether the terminal device supports blind retransmission of the first channel based on the terminal capability information of blindly retransmitting the first channel indicated by the terminal capability signaling, and when it is determined that the terminal device supports blind retransmission of the first channel, configure and / or instruct the terminal device to blindly retransmit the first channel, such as configuring a reasonable number of retransmissions for the terminal device so that the terminal device performs repeated transmission of the first channel based on the number of retransmissions.

[0203] In some embodiments, when the first information is auxiliary information, the network device can make relevant decisions on the terminal device's blind retransmission of the first channel by analyzing the auxiliary information, such as configuring a reasonable retransmission number value for the terminal device so that the terminal device repeats the transmission of the first channel based on the retransmission number value. The auxiliary information may include at least one of the following: an RSRP measurement value; an RSRP threshold; an RSRP quantization value; a blind retransmission request for the first channel. The RSRP quantization value may be a quantized value of the RSRP measurement value, and the RSRP threshold may be used to compare with the RSRP measurement value. For example, the network device may determine the number of retransmissions of the first channel based on the RSRP measurement result and the threshold. The RSRP threshold and the RSRP quantization value may be associated with PRACH resources, or associated with DMRS resources, or associated with LCID, or different values ​​of several bits to indicate different RSRP values. Different RSRP thresholds and RSRP quantization values ​​may correspond to different transmission times. The correspondence between the RSRP threshold, the RSRP quantization value, and the number of retransmissions 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.

[0204] The communication processing method provided by the embodiment of the present disclosure provides a mechanism for early reporting of terminal capabilities and / or auxiliary information, so that the base station can configure a reasonable number of retransmission times for the terminal to ensure the coverage enhancement effect of Msg5 and subsequent PUSCH channels.

[0205] To illustrate the specific execution process of the terminal device, Figure 4 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.

[0206] Step 201: Send first information, where the first information is used by a network device to determine a configuration and / or instruct a terminal to blindly retransmit a first channel.

In some embodiments, transmission on the first channel occurs after the terminal receives Msg4 sent by the network device and before the terminal device receives RRC reconfiguration signaling sent by the network device.

[0209] In some embodiments, the terminal device may send a first message to a network device (such as a base station) through any one of Msg1, Msg3, and Msg5. After receiving the first message, the network device may determine whether the terminal device supports repeated transmission of Msg5 based on the first information. When judging that the terminal device supports repeated transmission of Msg5, a reasonable retransmission number value is configured for the terminal device to ensure the coverage enhancement effect of Msg5 and subsequent PUSCH channels.

Different first information may correspond to different PRACH resource combinations, and different first information 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, by adding a new Msg5-repetition-r19 field in the RRC IE FeatureCombination-r17 configured by the network device to configure a separate PRACH resource for repeated transmission of the first channel.

[0212] In some embodiments, when the terminal device sends the first information to the network device based on Msg3: as a possible implementation method, the first information can be distinguished (such as distinguishing different time domains, frequency domains and code domains, etc.) by the demodulation reference signal (DMRS) of Msg3, and different first information can correspond to different DMRS. 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 by the joint action of protocol provisions and network device configuration, and no specific limitation is made here.

As a possible implementation method, the terminal device may use the new RRC signaling carried in the Msg3 MAC PDU to indicate the first information. As a possible implementation method, the terminal device may indicate the first information through the physical layer bit attached to the payload after the Msg3 MAC PDU is handed over to the physical layer.

[0213] In some embodiments, when the terminal device sends the first information to the network device based on Msg5; as a possible implementation method, the first information can be distinguished (such as distinguishing different time domains, frequency domains and code domains, etc.) by the demodulation reference signal (DMRS) of Msg5, and different first information can correspond to different DMRS. 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 be determined by the joint action of the protocol provisions and the network device configuration, and no specific limitation is made here.

As a possible implementation method, the terminal device may indicate the first information through the physical layer bit attached to the payload after the Msg5 MAC PDU is handed over to the physical layer.

[0214] In some embodiments, when the terminal device sends the first information to the network device, if the indication is displayed using bits, the index value configured in the auxiliary information corresponding list may also be indicated to the network device, thereby saving bit overhead. The auxiliary information list may include an RSRP threshold list, an RSRP quantization value list, etc. For example, when the terminal device sends the RSRP threshold in the auxiliary information to the network device, the RSRP threshold list configured by the network device may be {2, 4, 8}, and the index value configured by the terminal device may be 0, 1, 2, where the index value 0 corresponds to 2 in the RSRP threshold list, the index value 1 corresponds to 4 in the RSRP threshold list, and the index value 2 corresponds to 8 in the RSRP threshold list.

[0225] In some embodiments, when the network device receives the first information sent by the terminal based on Msg5, it may include at least one of the following: the first information indicated by the receiving terminal through the demodulation reference signal DMRS of Msg5, wherein different first information corresponds to different DMRS; the first information indicated by the receiving terminal through the new logical channel identifier LCID in the media access control MAC subheader corresponding to Msg5, wherein different LCIDs are used to indicate different first information; the first information indicated by the receiving terminal through the reserved bit of the MAC subheader corresponding to the media access control MAC CE or MAC SDU corresponding to Msg5; the first information indicated by the receiving terminal using the new or reused existing MAC CE in Msg5; the first information indicated by the receiving terminal using the reserved bit or the newly added bit in the RRCResumeComplete, RRCsetupComplete or RRCReestablishmentComplete corresponding to Msg5; the first information indicated by the receiving terminal using the new RRC signaling carried in the Msg5 MAC PDU; 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.

[0226] In some embodiments, when the above-mentioned network device receives the first information sent by the terminal device, if the indication is displayed through bits, the network device may also receive an index value (index in the repetition number list) configured in the auxiliary information corresponding list, thereby saving bit overhead. The auxiliary information list may include an RSRP threshold list, an RSRP quantization value list, etc. For example, when the terminal device sends the RSRP threshold in the auxiliary information to the network device, the RSRP threshold list configured by the network device may be {2, 4, 8}, and the index value configured by the terminal device may be 0, 1, 2, and the index value 0 corresponds to 2 in the RSRP threshold list, the index value 1 corresponds to 4 in the RSRP threshold list, and the index value 2 corresponds to 8 in the RSRP threshold list.

[0227] Among them, the auxiliary information list can be configured by the RRC signaling in SIB1 or Msg4. Optionally, if not configured, the auxiliary information list configured by Msg3 or the default auxiliary information list is used. Optionally, the use priority of the auxiliary information list configured by Msg3 is higher than the default auxiliary information list. In addition, a possible implementation method is that the RRC signaling in SIB1 and Msg4 can configure the auxiliary information list for the number of repeated transmissions. If the RRC signaling of SIB1 and Msg4 are both configured with the Msg5 auxiliary information list, the use priority can be defined. One possible way is: the use priority of the auxiliary information list configured by Msg4RRC is greater than the auxiliary information list configured by SIB1RRC. Optionally, the configured auxiliary information list may include the number of retransmissions 1. In some embodiments, the auxiliary information 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 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.

[0228] In some embodiments, for the case where the above-mentioned terminal device indicates the first information based on the Msg1 resource, the terminal device can directly determine whether the current network device supports blind retransmission of the first channel by whether the network device is configured with a separate PRACH resource; for the case where the above-mentioned terminal device sends the first information based on Msg1 and / or Msg3 and / or sends the first information based on Msg5, the network device can generate display enable signaling through SIB1 or RRC reconfiguration signaling, and the terminal device can send the first information based on Msg3 and / or Msg5 only after receiving the display enable signaling sent by the network device. The display enable signaling is used to indicate that the network device supports blind retransmission of the first channel; or, the terminal device can determine whether the current network has enabled blind retransmission of the first channel by whether the network device is configured with an RSRP threshold / RSRP quantization value.

[0229] Step 302: Determine a configuration and / or instruct the terminal to blindly retransmit the first channel according to the first information.

[0230] In some embodiments, after receiving the first information, the network device may determine, based on the first information, whether the terminal device supports repeated transmission of Msg5. When determining that the terminal device supports repeated transmission of Msg5, the network device may configure a reasonable retransmission count value for the terminal device to ensure coverage enhancement for Msg5 and subsequent PUSCH channels. In some embodiments, after receiving the first information, the network device may further configure a retransmission count value of 1 for the terminal device, or not configure a retransmission count.

[0231] In some embodiments, when the first information is terminal capability signaling, the network device may directly determine whether the terminal device supports blind retransmission of the first channel based on the terminal capability information of blindly retransmitting the first channel indicated by the terminal capability signaling, and when it is determined that the terminal device supports blind retransmission of the first channel, configure and / or instruct the terminal device to blindly retransmit the first channel, such as configuring a reasonable number of retransmissions for the terminal device so that the terminal device performs repeated transmission of the first channel based on the number of retransmissions.

[0232] In some embodiments, when the first information is auxiliary information, the network device can make relevant decisions on the terminal device's blind retransmission of the first channel by analyzing the auxiliary information, such as configuring a reasonable retransmission number value for the terminal device so that the terminal device repeats the transmission of the first channel based on the retransmission number value. The auxiliary information may include at least one of the following: an RSRP measurement value; an RSRP threshold; an RSRP quantization value; a blind retransmission request for the first channel. The RSRP quantization value may be a quantized value of the RSRP measurement value, and the RSRP threshold may be used to compare with the RSRP measurement value. For example, the network device may determine the number of retransmissions of the first channel based on the RSRP measurement result and the threshold. The RSRP threshold and the RSRP quantization value may be associated with PRACH resources, or associated with DMRS resources, or associated with LCID, or different values ​​of several bits to indicate different RSRP values. Different RSRP thresholds and RSRP quantization values ​​may correspond to different transmission times. The correspondence between the RSRP threshold, the RSRP quantization value, and the number of retransmissions 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.

[0233] The communication processing method provided by the embodiment of the present disclosure provides a mechanism for early reporting of terminal capabilities and / or auxiliary information. The network device can receive the first information sent by the terminal device, determine the configuration and / or instruct the terminal to blindly retransmit the first channel based on the first information, and ensure the coverage enhancement effect of Msg5 and subsequent PUSCH channels.

[0315] The present disclosure proposes a communication processing method and device, and provides a terminal capability and / or auxiliary information advance reporting mechanism, so that the base station can configure a reasonable retransmission number value for the terminal to ensure the coverage enhancement effect of Msg5 and subsequent PUSCH channels.

[0316] Based on this disclosure, examples of embodiments of this solution are as follows:

[0317] Consider at least one of the following mechanisms for early reporting of terminal capabilities and / or auxiliary information:

[0318] Direction 1: The terminal reports whether it supports Msg5 PUSCH and subsequent blind retransmissions of PUSCH scheduled by DCI format 0_0 with CRC scrambled by C-RNTI based on Msg1 / 3 / 5.

[0319] opt.1: Terminal capability indication based on Msg1PRACHresource

[0320] Based on this, the base station needs to configure a set of separate PRACH resources for Msg5 PUSCH and subsequent PUSCH repetition capability indicating. It can be shared RO with separate preambles or separate PRACH configuration.

[0321] opt.2: Terminal capability indication based on Msg3

[0322] Method 1: Indication based on Msg3 separate DMRS resource (frequency / time / sequence)

[0323] Method 2: Introduce a new LCID, or use the spare bit in the MAC subheader, or use the legacy or new MAC CE, or use the spare bit or a new bit in RRCsetupRequest, RRCResumeRequest, or RRCReestablishmentRequest, or design a new RRC capability signaling bearer to be reported in the Msg3 MAC PDU. Alternatively, after the MAC PDU is handed over to the physical layer, a physical layer bit is added to the payload to indicate the capability.

[0324] Opt.3: Terminal capability indication based on Msg5 to enhance subsequent PUSCH uplink coverage

[0325] Method 1: Indication based on Msg5 separate DMRS resource

[0326] Method 2 uses a new LCID, a spare bit in the MAC subheader, a legacy or new MAC CE, a reserved bit or a new field in RRCResumeComplete, RRCsetupComplete, or RRCReestablishmentComplete, or designs a new RRC capability signaling bearer for reporting in the Msg5 MAC PDU. Alternatively, after the MAC PDU is handed over to the physical layer, a physical layer bit is added to the payload to indicate the capability.

[0327] Note: For opt.2 / 3, the base station needs to design the enable field for Msg5 and subsequent PUSCH repetition through SIB1 or RRC reconfiguration signaling. Only when the base station indicates to enable Msg5 and later PUSCH repetition can the terminal indicate the terminal capability based on opt.2 / 3. For opt.1, whether the current network supports Msg5 and later PUSCH repetition can be directly determined by whether the gNB configures a separate PRACH resource.

[0328] Direction 2: The terminal reports auxiliary information based on Msg1 / 3 / 5 to assist the base station in making decisions related to Msg5 and subsequent PUSCH transmission times and resource scheduling.

[0329] opt.1: Terminal capability indication based on Msg1PRACH resource

[0330] Based on this, the base station needs to configure one or more separate PRACH resource sets for Msg5 PUSCH and subsequent PUSCH repetition capability indication. This can be a shared RO with separate preambles or a separate PRACH configuration. In addition, the PRACH resource can be associated with an RSRP threshold. Different PRACH resource sets can be associated with different RSRP thresholds. The RSRP threshold can be configured by SIB1, OSI, or RRC signaling, or determined based on the Msg3 repetition threshold and / or multiple PRACH transmission threshold and / or a certain offset.

[0331] opt.2: Terminal capability indication based on Msg3

[0332] Method 1: Indicates (frequency / time / sequence) based on Msg3 separate DMRS resource. Different resources represent different RSRP quantization values ​​(thresholds). Different quantization values ​​(thresholds) can be configured by the base station or specified by the protocol.

[0333] Method 2: Introduce a new LCID, or use the spare bit in the MAC subheader, or use the legacy or new MAC CE, or use the spare bit or a new bit in RRCsetupRequest, RRCResumeRequest, or RRCReestablishment, or design a new RRC capability signaling bearer to be reported in the Msg3 MAC PDU. Alternatively, after the MAC PDU is handed over to the physical layer, a physical layer bit is added to the payload to indicate the capability.

[0334] Optionally, different LCIDs or different values ​​can be associated with different RSRP thresholds, or the reference signal measurement value (e.g., quantized value) can be reported in the above manner. Different quantized values ​​(thresholds) can be configured by the base station or specified by the protocol.

[0335] Opt.3: Terminal capability indication based on Msg5 to enhance subsequent PUSCH uplink coverage

[0336] Method 1: Indicate based on Msg5 separate DMRS resource. Different resources represent different RSRP quantization values ​​(thresholds). Different quantization values ​​(thresholds) can be configured by the base station or specified by the protocol.

[0337] Method 2 uses a new LCID, a spare bit in the MAC subheader, a legacy or new MAC CE, a reserved bit or a new field in RRCResumeComplete, RRCsetupComplete, or RRCReestablishment, or designs a new RRC capability signaling bearer for reporting in the Msg5 MAC PDU. Alternatively, after the MAC PDU is handed over to the physical layer, a physical layer bit is added to the payload for indication.

[0338] Optionally, different LCIDs or different values ​​can be associated with different RSRP thresholds, or the reference signal measurement value (e.g., the RSRP value of the quantized SSS) can be reported in the above manner. Different quantization values ​​(thresholds) can be configured by the base station or specified by the protocol.

[0339] Note: For opt.2 / 3, the base station needs to design the enable field for Msg5 and subsequent PUSCH repetition through SIB1 or RRC reconfiguration signaling. Only when the base station indicates to enable Msg5 and later PUSCH repetition can the terminal indicate the terminal capability based on opt.2 / 3. For opt.1, whether the current network supports Msg5 and subsequent PUSCH repetition can be directly determined by whether the gNB configures a separate PRACH resource.

[0340] One possible approach is to report Msg5 and subsequent channels separately. Optionally, for the channels mentioned under the Direction, different channels have different RSRP thresholds.

[0341] In addition, if Direction 2 is used for auxiliary information reporting, it also implicitly indicates that the terminal supports Msg5 and subsequent PUSCH repetition. Optionally, there is no need to use Direction 1 for early reporting of terminal capabilities.

[0342] Others

[0343] The base station configures and indicates the number of repetitions. The gNB may indicate the number of repetitions for Msg5 and subsequent PUSCH only if the terminal reports terminal capabilities and / or reports auxiliary information (Msg5 repetition request).

[0344] Optionally, even if the terminal reports terminal capabilities and / or auxiliary information (Msg5 repetition request), the gNB may indicate to the terminal that the number of repetitions is 1, or not configure or indicate repetition.

[0345] In summary, the present disclosure has the following beneficial effects: it provides a mechanism for reporting terminal capabilities and / or auxiliary information in advance, and the network device can receive the first information sent by the terminal device, determine the configuration and / or instruct the terminal to blindly retransmit the first channel based on the first information, and ensure the coverage enhancement effect on Msg5 and subsequent PUSCH channels.
