In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described below. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the embodiments of the present application. protected range.

With people's pursuit of speed, delay, high-speed mobility, energy efficiency, and the diversity and complexity of business in future life, the ^3rd Generation Partnership Project (3GPP) international standards organization began to develop 5G . The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), Massive Machine-Type Communications (mMTC) ).

On the one hand, eMBB still aims at users obtaining multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, the capabilities and requirements vary greatly, so it cannot be generalized, and detailed analysis must be combined with specific deployment scenarios. Typical applications of URLLC include: industrial automation, electric power automation, telemedicine operations (surgery), traffic safety guarantee, etc. The typical characteristics of mMTC include: high connection density, small data volume, delay-insensitive services, low cost and long service life of modules, etc.

RRC state

In order to reduce air interface signaling, quickly restore wireless connections, and quickly restore data services, 5G defines a new RRC state, that is, the RRC_INACTIVE state. This state is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state. in,

1) RRC_IDLE state (referred to as idle (idle) state): Mobility is UE-based cell selection and reselection, paging is initiated by the core network (Core Network, CN), and the paging area is configured by the CN. There is no UE context and no RRC connection at the base station side.

2) RRC_CONNECTED state (connected state for short): there is an RRC connection, and UE context exists on the base station side and the UE side. The network side knows the location of the UE at the specific cell level. Mobility is mobility controlled by the network side. Unicast data can be transmitted between the UE and the base station.

3) RRC_INACTIVE state (referred to as inactive (inactive) state): Mobility is UE-based cell selection and reselection, there is a connection between CN-NR, UE context exists on a certain base station, paging is triggered by RAN, based on The paging area of the RAN is managed by the RAN, and the network side knows the location of the UE based on the paging area level of the RAN.

beam sweeping

NR will be deployed on high frequencies in the future. In order to improve coverage, in 5G, the mechanism of beam sweeping is introduced to meet the coverage requirements (use space for coverage and time for space). After the introduction of beam sweeping, synchronization signals need to be sent in each beam direction. 5G synchronization signals are given in the form of SSB, including primary synchronization signal (Primary Synchronization Signal, PSS), secondary synchronization signal (Secondary Synchronization Signal, SSS) , and Physical Broadcast Channel (Physical Broadcast Channel, PBCH). The synchronization signal of 5G appears periodically in the time domain in the form of a synchronization signal burst set (SS burst set).

MBMS

MBMS is a technology that transmits data from one data source to multiple terminal devices by sharing network resources. This technology can effectively use network resources while providing multimedia services, and realize broadcasting of multimedia services at a higher rate (such as 256kbps) and multicast.

Due to the low spectrum efficiency of MBMS, it is not enough to effectively carry and support the operation of mobile TV services. Therefore, in LTE, 3GPP clearly proposed to enhance the ability to support downlink high-speed MBMS services, and determined the design requirements for the physical layer and air interface.

3GPP R9 introduces evolved MBMS (evolved MBMS, eMBMS) into LTE. eMBMS proposes the concept of Single Frequency Network (SFN), that is, Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN). MBSFN uses a unified frequency to transmit service data in all cells at the same time, but To ensure the synchronization between cells. This method can greatly improve the overall signal-to-noise ratio distribution of the cell, and the spectrum efficiency will also be greatly improved accordingly. eMBMS implements broadcast and multicast of services based on the IP multicast protocol.

In LTE or LTE-Advanced (LTE-Advanced, LTE-A), MBMS only has a broadcast bearer mode, but no multicast bearer mode. In addition, the reception of MBMS service is applicable to terminal equipments in idle state or connected state.

3GPP R13 introduced the concept of Single Cell Point To Multiploint (SC-PTM), and SC-PTM is based on the MBMS network architecture.

MBMS introduces new logical channels, including Single Cell-Multicast Control Channel (Single Cell-Multicast Control Channel, SC-MCCH) and Single Cell-Multicast Transport Channel (Single Cell-Multicast Transport Channel, SC-MTCH). SC-MCCH and SC-MTCH are mapped to the downlink shared channel (Downlink-Shared Channel, DL-SCH), and further, DL-SCH is mapped to the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), wherein, SC - MCCH and SC-MTCH belong to logical channels, DL-SCH belongs to transport channels, and PDSCH belongs to physical channels. SC-MCCH and SC-MTCH do not support Hybrid Automatic Repeat reQuest (HARQ) operation.

MBMS introduces a new system information block (System Information Block, SIB) type, namely SIB20. Specifically, SIB20 is used to transmit SC-MCCH configuration information, and one cell has only one SC-MCCH. The SC-MCCH configuration information includes: SC-MCCH modification period, SC-MCCH repetition period, and information such as radio frames and subframes for scheduling SC-MCCH. Further, 1) the boundary of the modification period of SC-MCCH satisfies SFN mod m=0, wherein, SFN represents the system frame number of the boundary, and m is the modification period (ie sc-mcch-ModificationPeriod) of the SC-MCCH configured in SIB20. 2) Scheduling the wireless frame of SC-MCCH satisfies: SFN mod mcch-RepetitionPeriod=mcch-Offset, wherein, SFN represents the system frame number of the wireless frame, mcch-RepetitionPeriod represents the repetition period of SC-MCCH, and mcch-Offset represents SC-MCCH offset. 3) The subframe for scheduling the SC-MCCH is indicated by sc-mcch-Subframe.

The SC-MCCH is scheduled through a Physical Downlink Control Channel (PDCCH). On the one hand, a new radio network temporary identity (Radio Network Tempory Identity, RNTI), that is, a single cell RNTI (Single Cell RNTI, SC-RNTI) is introduced to identify the PDCCH (such as SC-MCCH PDCCH) used to schedule the SC-MCCH, Optionally, the fixed value of SC-RNTI is FFFC. On the other hand, a new RNTI is introduced, that is, a single cell notification RNTI (Single Cell Notification RNTI, SC-N-RNTI) to identify the PDCCH used to indicate the change notification of the SC-MCCH (such as notifying the PDCCH). Optionally, the SC The fixed value of -N-RNTI is FFFB; further, one of the 8 bits (bits) of DCI 1C can be used to indicate the change notification. In LTE, SC-PTM configuration information is based on SC-MCCH configured by SIB20, and then SC-MCCH configures SC-MTCH, and SC-MTCH is used to transmit service data.

Specifically, the SC-MCCH only transmits one message (that is, SCPTMConfiguration), which is used to configure configuration information of the SC-PTM. The configuration information of SC-PTM includes: temporary mobile group identity (Temporary Mobile Group Identity, TMGI), session identification (seession id), group RNTI (Group RNTI, G-RNTI), discontinuous reception (Discontinuous Reception, DRX) configuration information And the SC-PTM service information of the neighboring cell, etc. It should be noted that SC-PTM in R13 does not support Robust Header Compression (Robust Header Compression, ROHC) function.

The downlink discontinuous reception of SC-PTM is controlled by the following parameters: onDurationTimerSCPTM, drx-InactivityTimerSCPTM, SC-MTCH-SchedulingCycle, and SC-MTCH-SchedulingOffset.

When [(SFN*10)+subframe number]modulo(SC-MTCH-SchedulingCycle)=SC-MTCH-SchedulingOffset is satisfied, start the timer onDurationTimerSCPTM;

When receiving downlink PDCCH scheduling, start the timer drx-InactivityTimerSCPTM;

The downlink SC-PTM service is received only when the timer onDurationTimerSCPTM or drx-InactivityTimerSCPTM is running.

SC-PTM business continuity adopts the concept of MBMS business continuity based on SIB15, that is, "SIB15+MBMSInterestIndication" mode. The service continuity of terminal equipment in idle state is based on the concept of frequency priority.

In the technical solution of the embodiment of the present application, a new SIB (called the first SIB) is defined, and the first SIB includes the configuration information of the first MCCH. Here, the first MCCH is the control channel of the MBMS service. In other words, the first SIB includes the configuration information of the first MCCH. One SIB is used to configure the configuration information of the NR MBMS control channel. Optionally, the NR MBMS control channel may also be called NR MCCH (that is, the first MCCH).

Further, the first MCCH is used to carry the first signaling. The embodiment of the present application does not limit the name of the first signaling. For example, the first signaling is signaling A, and the first signaling includes at least one first MTCH configuration information, here, the first MTCH is a traffic channel (also referred to as a data channel or a transmission channel) of the MBMS service, and the first MTCH is used to transmit MBMS service data (such as NR MBMS service data). In other words, the first MCCH is used to configure the configuration information of the traffic channel of NR MBMS. Optionally, the traffic channel of NR MBMS may also be called NR MTCH (that is, the first MTCH).

Specifically, the first signaling is used to configure an NR MBMS traffic channel, service information corresponding to the traffic channel, and scheduling information corresponding to the traffic channel. Further, optionally, the service information corresponding to the service channel, such as TMGI, session id and other identification information for identifying services. The scheduling information corresponding to the traffic channel, for example, the RNTI used when the MBMS service data corresponding to the traffic channel is scheduled, such as G-RNTI, DRX configuration information, and the like.

It should be noted that both the transmission of the first MCCH and the first MTCH are scheduled based on the PDCCH. Wherein, the RNTI used by the PDCCH for scheduling the first MCCH uses a network-wide unique identifier, that is, a fixed value. The RNTI used by the PDCCH for scheduling the first MTCH is configured through the first MCCH.

It should be noted that, in this embodiment of the present application, there is no restriction on naming of the first SIB, the first MCCH, and the first MTCH. For ease of description, the first SIB can also be referred to as the SIB for short, the first MCCH can also be referred to as the MCCH for short, and the first MTCH can also be referred to as the MTCH for short, and the PDCCH (ie, the MCCH PDCCH) configured to schedule the MCCH is configured by the SIB. ) and notify the PDCCH, wherein, the PDSCH (ie MCCH PDSCH) used to transmit the MCCH is scheduled by the DCI carried by the MCCH PDCCH. Further, configure M PDCCHs for scheduling MTCH (ie MTCH 1 PDCCH, MTCH 2 PDCCH, ..., MTCH M PDCCH) through MCCH, wherein, the DCI scheduling carried by MTCH n PDCCH is used to transmit the PDSCH of MTCH n (ie MTCH n PDSCH), n is an integer greater than or equal to 1 and less than or equal to M. MCCH and MTCH are mapped to DL-SCH, and further, DL-SCH is mapped to PDSCH, wherein MCCH and MTCH belong to logical channels, DL-SCH belongs to transport channel, and PDSCH belongs to physical channel.

It should be noted that although the foregoing solution is described using MBMS as an example, the description of "MBMS" may also be replaced with "MBS". The embodiment of the present application uses MBS as an example for description, and the description of "MBS" may also be replaced with "MBMS".

In the NR system, many scenarios need to support multicast and broadcast business requirements, such as in the Internet of Vehicles and the Industrial Internet. So it is necessary to introduce multicast and broadcast MBS services in NR. It should be noted that the multicast-type MBS service refers to an MBS service transmitted in a multicast manner (abbreviated as MBS multicast service). The broadcast-type MBS service refers to an MBS service transmitted in a broadcast mode (referred to as an MBS broadcast service for short).

In the RRC idle state, the RRC inactive state, and the RRC connected state, all terminal devices in these three RRC states can receive broadcast-type MBS services (abbreviated as MBS broadcast services). For a terminal device in the RRC connection state, in order to support the reception of the MBS broadcast service, it is necessary to obtain the signaling configuration corresponding to the MBS broadcast service. How to obtain the signaling configuration corresponding to the MBS broadcast service is a problem that needs to be solved. To this end, the following technical solutions of the embodiments of the present application are proposed.

It should be noted that the technical solutions of the embodiments of the present application are applicable to broadcast-type MBS services (referred to as MBS broadcast services for short).

It should be noted that the technical solutions of the embodiments of the present application are applicable to carrier aggregation (Carrier Aggregation, CA) and dual connectivity (Dual-Connectivity, DC) scenarios,
