The method includes at least some of the following.

S210: the terminal equipment sends an MCCH signaling request based on random access;

s220: and determining whether the MCCH signaling request is successful according to a response message for the MCCH request received from the network equipment.

In the step S210, the terminal device may send the MCCH signaling request based on random access in at least three ways:

mode one: an MCCH signaling request based on a random access message 1 (MSG 1) is transmitted.

Mode two: an MCCH signaling request based on a message a for random access (MSG a) is transmitted.

Mode two: an MCCH signaling request based on a random access message 3 (MSG 2) is transmitted.

Among them, the first and third modes are applicable to a 4-step random access (4 step-RACH) mode, and the second mode is applicable to a 2-step random access (2-step RACH) mode. The three ways described above are described below in connection with fig. 3, 4 and 5, respectively.

Embodiment one:

fig. 3 is a schematic diagram of an MCCH signaling request mode based on MSG 1 according to an embodiment of the present application, including the following steps:

step S310: the transmission state of the current MCCH signaling is configured in the system broadcast, such as whether the current MCCH signaling is being transmitted or not transmitted. Or whether the MCCH signaling is configured in the system broadcast to be sent based on the UE request.

Accordingly, a terminal device (UE) receives a system broadcast message, which includes at least one of:

The sending state of the current MCCH signaling;

whether the MCCH signaling is sent based on a terminal device request.

Step 310 is an optional step.

Step S320: the system broadcasts or RRC signaling configures random access channel occasions (ROs, random Access Channel Occasion) and/or random access preamble (preamble) resources for the UE to request MCCH signaling. If the resource is configured, the UE adopts the MCCH signaling request based on MSG 1, otherwise, the UE adopts the MCCH signaling request based on MSG 3.

Correspondingly, the UE receives a system broadcast message or RRC signaling; the system broadcast message or RRC signaling carries an RO for the terminal device to request the MCCH signaling and/or a preamble for the terminal device to request the MCCH signaling.

Step S330: the UE transmits MSG 1 of the random access procedure based on the configured RO or preamble.

Step S340: the base station (e.g., gNB) transmits MSG 2. Specifically, the base station transmits a random access response (RAR, random Access Response) or a physical downlink control channel (PDCCH, physical Downlink Control Channel) scrambled by a random access radio network temporary identity (RA-RNTI, radio Network Tempory Identity).

Step S350: if the UE sends the MSG 1 of the random access procedure based on the configured preamble in step S330, that is, the resource for sending the MCCH signaling request is the preamble; then in this case, if a RAR containing the random access preamble identification (rapid, random Access Preamble ID) of the preamble is received, the UE determines that the MCCH signaling request is successful.

If the UE sends MSG 1 of the random access procedure based on the configured RO in step S330, that is, the resource for sending the MCCH signaling request is RO; in this case, the UE determines that the MCCH signaling request is successful if a PDCCH scrambled with the RO corresponding RA-RNTI is received.

Step S360: and the base station sends the MCCH signaling, and the UE receives the MCCH signaling.

Wherein the recommended SSB index list has at least the following forms:

first, when a synchronization signal (SS, synchronization Signal) burst contains at most 4 SSBs or 8 SSBs, the recommended SSB index list is 8 bits in length, and each bit corresponds to an SSB index for indicating whether to transmit MCCH signaling on a beam to which the SSB index corresponds. For example, if the corresponding bit is set to 1, the SSB index requests transmission of MCCH signaling.

Second, when one SS burst set contains at most 64 SSBs, the recommended SSB index list length is 8 bits, wherein the first 4 bits correspond to four consecutive SSB indexes larger than the first SSB, and the last 4 bits correspond to four consecutive SSB indexes smaller than the first SSB, respectively; wherein,

the first SSB comprises an SSB index corresponding to a beam for sending a random access indication;

each bit in the recommended SSB index list is used to indicate whether to send MCCH signaling on the beam corresponding to the corresponding SSB index. For example, if the corresponding bit is set to 1, the SSB index requests transmission of MCCH signaling.

Third, when one SS burst set contains at most 64 SSBs, the recommended SSB index list length is 8 bits, wherein the first 4 bits correspond to four consecutive SSB indexes smaller than the first SSB, and the last 4 bits correspond to four consecutive SSB indexes larger than the first SSB, respectively; wherein,

Fourth kind: when the SS burst set contains 64 SSBs at most, the recommended SSB index list is 8 bits in length, wherein the first 4 bits respectively correspond to four consecutive actually transmitted SSB indexes larger than the first SSB, and the last 4 bits respectively correspond to four consecutive actually transmitted SSB indexes smaller than the first SSB; wherein,

Fifth: when the SS burst set contains 64 SSBs at most, the recommended SSB index list is 8 bits in length, wherein the first 4 bits respectively correspond to four consecutive actually transmitted SSB indexes smaller than the first SSB, and the last 4 bits respectively correspond to four consecutive actually transmitted SSB indexes larger than the first SSB; wherein,

Step S430: the network side sends MSG B.

Step S440: if the UE receives the MSG B, the UE determines that the MCCH signaling request is successful.

Step S450: and the base station sends the MCCH signaling, and the UE receives the MCCH signaling.

Alternatively, the base station may decide on which beams to send MCCH signaling according to the SSB index list recommended by the UE in step S420. For example:

if the SSB index list is provided in the MSG a, the network side may send MCCH signaling on the beam corresponding to the SSB index list.

Or if the SSB index list is not provided in the MSG a, the network side may send the MCCH signaling on a preamble sent by the UE and/or a beam corresponding to the SSB associated with the RO.

Alternatively, the network side may send MCCH signaling on all beams of the cell.

Embodiment III:

Step S550: the network side sends MSG 4, and the UE receives MSG 4. If the conflict resolution is determined to be successful according to MSG 4, the UE determines that the MCCH signaling request is successful.

Step S560: and the base station sends the MCCH signaling, and the UE receives the MCCH signaling.

Alternatively, the base station may decide on which beams to send MCCH signaling according to the SSB index list recommended by the UE in step S540. For example:

if the SSB index list is provided in MSG 3, the network side may send MCCH signaling on the beam corresponding to the SSB index list.

Or if the SSB index list is not provided in the MSG 3, the network side may send the MCCH signaling on a preamble sent by the UE and/or a beam corresponding to the SSB associated with the RO.

Wherein the recommended SSB index list has at least the following forms:

first, when a synchronization signal (SS, synchronization Signal) burst set contains at most 4 SSBs or 8 SSBs, the recommended SSB index list is 8 bits in length, and each bit corresponds to an SSB index for indicating whether or not to transmit system broadcast information on a beam to which the SSB index corresponds. For example, if the corresponding bit is set to 1, the SSB index requests transmission of system broadcast information.

each bit in the recommended SSB index list is used to indicate whether or not to transmit system broadcast information on the beam corresponding to the corresponding SSB index. For example, if the corresponding bit is set to 1, the SSB index requests transmission of system broadcast information.

Based on the request of the terminal device, the base station may transmit system broadcast information. Alternatively, the base station may decide on which beam to send the system broadcast information according to the SSB index list recommended by the UE. For example:
