For a better understanding of the technical solutions of the embodiments of the present application, the following will be described first:

RedCAP UE introduction

The R17 version of the protocol supports low capability terminals, and the capability of such redcap terminals is mainly reduced compared to old/legacy terminals, as shown in table 1:

TABLE 1

Random access procedure

NR supports two types of random access procedures: 4-step RA type (4-step RACH) of MSG1 and 2-step RA type (2-step RACH) of MSGA. Both types of RA procedures support Contention Based Random Access (CBRA) and Contention Free Random Access (CFRA).

The UE selects a type of random access based on the network configuration:

(1) When the CFRA resources are not configured, the UE selects a 2-step RA type and a 4-step RA type based on the RSRP threshold;

(2) When CFRA resources are configured for the 4-step RA type, the UE performs random access using the 4-step RA type;

(3) When CFRA resources are configured for the 2-step RA type, the UE performs random access using the 2-step RA type.

4-step RACH procedure based on contention

In the 4-step RACH, the UE firstly transmits MSG1 to the network, and the MSG1 comprises a preamble; after the UE sends the preamble, it will monitor the PDCCH in the RAR time window (RA Response window), and use a fallback (fallback) DCI format, i.e., DCI format 1_0, to receive a random access response Random Access Response (RAR) of the PDCCH schedule scrambled with the RA-RNTI. If the preamble index in the RAR is the same as the preamble index sent by the UE, the UE considers that the RAR is successfully received, and then stops monitoring the RAR and sends MSG3 according to the UL grant indication carried in the RAR; MSG3 transmits on UL-SCH, and uses HARQ, scrambles PDCCH with TC-RNTI indicated by RAR, and schedules retransmission of MSG3 with a fallback (fallback) DCI format, i.e., DCI format 1_0. The MSG3 contains a UE-unique flag. This flag will be used for conflict resolution in step four. After the network receives the MSG3, the network schedules the PDCCH scrambled by the TC-RNTI to the MSG4, and when the UE successfully decodes UE Contention Resolution Identity MAC control element contained in the MSG4 and UE Contention Resolution Identity sent by the MSG3 are matched, the UE considers that the random access is successful and sets the C-RNTI of the UE as the TC-RNTI, namely the 4-step random access is completed.

The MSGA advanced recognition and principle is not repeated.

In one possible implementation manner, the carrying manner of the first target information includes one or more of the following:

Specifically, the MAC PDU format of the PUSCH of MSG3 and/or MSGA at the MAC layer is: the MAC subheader (including legacy LCID) +mac SDU (including new 64-bit RRC message (RRC setup request message, RRC resume request message, RRC reestablishment request message, system information request message), applicable to the case of non full I-RNTI (i.e. the case of 48-bit legacy RRC message)), the legacy LCID being the LCID corresponding to the current 64-bit RRC message, and using the LCID corresponding to the new 64-bit RRC message, wherein the new 64-bit RRC message is a new IE added to the legacy 48-bit RRC message for indicating the first target information;

In this embodiment, the legacy LCID of the 64-bit RRC message is used, so that the RRC message identified by the legacy LCID has a message size of 64 bits, and 48 bits of the 64-bit RRC message is an existing 48-bit legacy RRC message, and then there is a corresponding message size of 16 bits to indicate the first target information, that is, the 48-bit legacy RRC message and the 16-bit first target information form the new 64-bit RRC message.

Or specifically, the MAC PDU format of the PUSCH of the MSG3 and/or the MSGA at the MAC layer is: MAC subheader (including new LCID) +mac SDU (including new RRC message); the new RRC message size is larger than the legacy RRC message size, i.e. a new IE should be added to the new RRC message for indicating additional information, relative to the legacy RRC message;

in the embodiment of the present application, the new RRC message with the size of 80 bits is indicated by the introduced LCID, and the new RRC message with the size of 80 bits includes a legacy RRC message with the size of 64 bits and first target information with the size of 16 bits, that is, the new RRC message is composed of the legacy RRC message with the size of 64 bits and the first target information with the size of 16 bits.

The following describes aspects of the present application in connection with specific embodiments:

In the first embodiment of the invention: the RedCAP UE enables the network to clearly identify the RedCAP UE based on the MSG-3 advanced identification method

Step 1: if the UE is a RedCap UE and the network does not configure a preamble dedicated for the RedCap UE, or the network does not configure PRACH resources dedicated for the RedCap UE, or the UE selects PRACH resources of legacy UE and the MAC entity of the UE selects RA preambles of legacy UE.

Step 2: the RedCap UE sends MSG3, wherein a newly introduced logical channel ID is used in the MAC subheader in MSG3, and the newly introduced logical channel ID is an unused value in the current uplink LCID, and is used for reporting that the UE is a RedCap UE type.

The carrying mode of the reported message comprises the following steps:

(1) Two newly introduced lcid+legacy RRC messages, the newly introduced LCID corresponding to the legacy RRC messages. For example, introducing a UL-CCCHX logical channel still carries a legacy 48 bit-sized RRC setup request message or a 48bit RRC resume request message or a 64bit RRC setup request message

(2) A new lcid+a new MAC ce+legacy RRC message;

i.e. the newly introduced LCID corresponds to a new MAC CE in which the indication information that the UE is a RedCap UE is carried

(3) legacy LCID+new 64-bit RRC message (setup-request and resume-request) applicable to non-full I-RNTI, the new RRC message can add new IE for reporting indication information of UE being RedCap UE

The second embodiment of the invention: the RedCAP UE enables the network to clearly identify the RedCAP UE based on the MSG1 advanced identification method

Step 1: if the UE is a RedCap UE, and the network configures a preamble specific to the RedCap UE, and the MAC entity selects an RA preamble specific to the RedCap UE, or the network configures PRACH resources specific to the RedCap UE, and the UE selects PRACH resources specific to the RedCap UE.

Step 2: the RedCAP UE transmits MSG 3, and determines whether to report additional information according to a first criterion (namely the first configuration information);

the additional information includes at least one of:

(1) The number of the receiving antennas comprises the steps of indicating that the RedCAP UE is 1Rx RedCAP UE; or the RedCap UE is a 2Rx RedCap UE.

(2) The working mode supported by the terminal comprises indicating that the RedCAP UE is full-duplex FD RedCAP UE; or the RedCap UE is a half-duplex RedCap UE.

(3) Whether the terminal needs coverage enhancement includes whether the RedCap UE needs coverage enhancement.

(4) The modulation order level or maximum modulation coding level supported by the terminal comprises the step of indicating that the RedCAP UE maximally supports 64QAM in FR1 or that the RedCAP UE maximally supports 256 QAM in FR1

(5) The quality of the serving cell measured by the terminal;

(7) The maximum transmission rate supported by the terminal;

(8) Processing time supported by the terminal;

(11) The radio resource control RRC processing delay supported by the terminal.

(12) The information of other terminals is not particularly limited.

The first criterion includes:

(1) The number of the receiving antennas, if the number of the Rx antennas of the RedCAP UE is a first value, the Rx antennas of the RedCAP UE use the original logic channel ID, and if the number of the Rx antennas of the RedCAP UE is a second value, the Rx antennas of the RedCAP UE use the newly introduced logic channel ID; the Rx number is a positive integer greater than or equal to 1.

(2) The terminal uses the original logical channel ID if the working format supported by the RedCap UE is a first value, for example, and uses the newly introduced logical channel ID if the working format supported by the RedCap UE is a second value; the operation modes include half duplex, full duplex FD, and others.

(3) Whether the terminal needs coverage enhancement, for example, if the RedCap UE wants to schedule using the coverage enhancement method later, then use the new logical channel ID, otherwise use the original logical channel ID; the criteria for the RedCap UE to determine whether coverage is required in a later scheduling procedure may be implemented by network configuration and/or predefining and/or the UE.

(4) The modulation order level or the maximum modulation coding level supported by the terminal, for example, if the modulation order supported by the RedCap UE at the maximum in FR1 is a first value, it uses the original logical channel ID, and if the modulation order supported by the RedCap UE at the maximum in FR1 is a second value, it uses the new logical channel ID; the modulation orders maximally supported by the RedCap UE in FR1 include 64qam,256qam, and others.
