In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following describes the technical solutions related to the embodiments of the present application.

With the pursuit of speed, delay, high speed mobility, energy efficiency and diversity and complexity of future life business, the third generation partnership project (3 ^rd Generation Partnership Project,3 GPP) international standards organization began developing 5G. The main application scenario of 5G is: enhanced mobile Ultra-wideband (enhanced Mobile Broadband, emmbb), low latency high reliability communication (URLLC), large-scale Machine-based communication (mctc).

On the one hand, embbs still target users to obtain multimedia content, services and data, and their demand is growing very rapidly. On the other hand, since an eMBB may be deployed in different scenarios, such as indoors, urban, rural, etc., its capabilities and requirements are also quite different, so that detailed analysis must be performed in connection with a specific deployment scenario, not in general. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical characteristics of mctc include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

RRC state

5G for the purposes of reducing air interface signaling and fast recovery of radio connections, fast recovery of data traffic, a new radio resource control (Radio Resource Control, RRC) state, namely an RRC INACTIVE (RRC_INACTIVE) state, is defined. This state is different from the RRC IDLE (rrc_idle) state and the RRC ACTIVE (rrc_active) state. Wherein, the liquid crystal display device comprises a liquid crystal display device,

1) Rrc_idle state (simply referred to as IDLE state): mobility is UE-based cell selection reselection, paging is initiated by a Core Network (CN), and paging areas are configured by the CN. The base station side has no UE context and no RRC connection.

2) Rrc_connected state (CONNECTED state for short): there is an RRC connection and UE contexts on the base station side and UE side. The network side knows that the location of the UE is cell specific. Mobility is network-side controlled mobility. Unicast data may be transmitted between the UE and the base station.

3) Rrc_inactive state (simply referred to as INACTIVE state): mobility is cell selection reselection based on UE, there is a connection between CN-NRs, UE context exists on a certain base station, paging is triggered by RAN, paging area based on RAN is managed by RAN, network side knows UE location is based on paging area level of RAN.

BWP

The maximum channel bandwidth in 5G may be 400MHz (i.e., wideband), which is large compared to the maximum channel bandwidth in LTE, 20 MHz. If the UE remains operating on a wideband carrier (i.e., maximum channel bandwidth), the power consumption of the UE is significant. It is suggested that the radio frequency bandwidth of the UE may be adjusted according to the actual throughput of the UE, for which the concept of BWP was introduced, the motivation for which was to optimize the power consumption of the UE. For example, the UE may be configured with a smaller bandwidth (i.e., a smaller BWP) if the UE has a low rate requirement, and a larger bandwidth (i.e., a larger BWP) if the UE has a high rate requirement. If the UE supports a high rate or operates in carrier aggregation (Carrier aggregation, CA) mode, the UE may be configured with multiple BWPs. In addition, another purpose of BWP is to trigger coexistence of multiple parameter sets (numerology) in one cell, e.g. BWP1 corresponds to numerology1 and BWP2 corresponds to numerology2.

The UE in the idle state or inactive state resides on an initial BWP, which is visible to the UE in the idle state or inactive state, on which the UE may acquire information such as a master information block (Master Information Block, MIB), remaining minimum system information (Remaining Minimum system Information, RMSI), other system information (Other System Information, OSI), paging (paging), and the like.

MBMS

MBMS, a technology for transmitting data from one data source to a plurality of UEs through a shared network resource, is introduced in 3GPP Release 6 (R6), and is capable of effectively utilizing network resources while providing multimedia services, and realizing broadcasting and multicasting of multimedia services at a higher rate (e.g., 256 kbps).

Due to the low MBMS spectrum efficiency in 3gpp R6, it is not sufficient to effectively carry and support the operation of the mobile tv type service. In LTE, 3GPP has therefore explicitly proposed to enhance the support capability for the downlink high speed MBMS service and to determine the design requirements for the physical layer and the air interface.

The 3gpp r9 introduces evolved MBMS (eMBMS) into LTE. eMBMS proposes the concept of a single frequency network (Single Frequency Network, SFN), i.e. a multimedia broadcast multicast service single frequency network (Multimedia Broadcast multicast service Single Frequency Network, MBSFN), wherein the MBSFN uses a unified frequency to simultaneously transmit traffic data in all cells, but synchronization between the cells is guaranteed. The method can greatly improve the overall signal-to-noise ratio distribution of the cell, and the frequency spectrum efficiency can be correspondingly and greatly improved. eMBMS implements broadcast and multicast of services based on IP multicast protocols.

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

A single cell point-to-multipoint (Single Cell Point To Multiploint, SC-PTM) concept is introduced in 3gpp r13, SC-PTM being based on the MBMS network architecture.

MBMS introduces new logical channels including Single Cell multicast control channel (SC-MCCH) and Single Cell multicast transport channel (SC-MTCH) and Single Cell-Multicast Transport Channel. The SC-MCCH and SC-MTCH are mapped onto a Downlink-Shared Channel (DL-SCH), and further, the DL-SCH is mapped onto a physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH), wherein the SC-MCCH and SC-MTCH belong to a logical Channel, the DL-SCH belongs to a transport Channel, and the PDSCH belongs to a physical Channel. The SC-MCCH and SC-MTCH do not support hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) operation.

MBMS introduces a new system information block (System Information Block, SIB) type, SIB20. Specifically, the configuration information of the SC-MCCH is transmitted through the SIB20, and one cell has only one SC-MCCH. The configuration information of the SC-MCCH comprises: the modification period of the SC-MCCH, the repetition period of the SC-MCCH, the radio frame and subframe for scheduling the SC-MCCH and other information. Further, 1) the boundary of the modification period of the SC-MCCH satisfies SFN mod m=0, where SFN represents a system frame number of the boundary, and m is a modification period (i.e., SC-MCCH-modification period) of the SC-MCCH configured in SIB20. 2) The radio frame of the scheduling SC-MCCH meets the following conditions: SFN mod MCCH-repetition period = MCCH-Offset, where SFN represents the system frame number of the radio frame, MCCH-repetition period represents the repetition period of the SC-MCCH, and MCCH-Offset represents the Offset of the SC-MCCH. 3) The subframes of the scheduling SC-MCCH are indicated by SC-MCCH-Subframe.

The SC-MCCH is scheduled through a physical downlink control channel (Physical Downlink Control Channel, PDCCH). In one aspect, a new radio network temporary identity (Radio Network Tempory Identity, RNTI), i.e., single Cell RNTI (SC-RNTI), is introduced to identify a PDCCH (e.g., SC-MCCH PDCCH) for scheduling the SC-MCCH, optionally with the SC-RNTI fixed value FFFC. On the other hand, a new RNTI, i.e., a single cell notification RNTI (Single Cell Notification RNTI, SC-N-RNTI) is introduced to identify a PDCCH (e.g., notification PDCCH) for indicating a change notification of the SC-MCCH, optionally, the SC-N-RNTI is fixed to a value of FFFB; further, the change notification may be indicated with one bit of 8 bits (bits) of DCI 1C. In LTE, the configuration information of SC-PTM is based on the SC-MCCH configured by SIB20, and then SC-MCCH configures SC-MTCH for transmitting service data.

Specifically, the SC-MCCH transmits only one message (i.e., scptm configuration) for configuring configuration information of the SC-PTM. The configuration information of the SC-PTM comprises: temporary mobile Group identity (Temporary Mobile Group Identity, TMGI), session identity (session id), group RNTI (G-RNTI), discontinuous reception (Discontinuous Reception, DRX) configuration information, SC-PTM service information of neighbor cells, and the like. Note that SC-PTM in R13 does not support the robust header compression (Robust Header Compression, ROHC) function.

The downlink discontinuous reception of the SC-PTM is controlled by the following parameters: onDuration TimerSCPTM, drx-Inactivity TimerSCPTM, SC-MTCH-scheduling cycle, and SC-MTCH-scheduling offset.

When [ (SFN 10) +subframe number ] module (SC-MTCH-scheduling cycle) =sc-MTCH-scheduling offset is satisfied, a timer ondurationtimerscpm is started;

when receiving downlink PDCCH scheduling, starting a timer drx-InactivityTimerSCPTM;

the downstream SC-PTM service is received only when the timer onduration timerscpm or drx-incaactyitimerscpm is running.

The SC-PTM service continuity adopts the MBMS service continuity concept based on SIB15, namely a mode of SIB15 and MBMSInterestindication. The traffic continuity of idle state UEs is based on the concept of frequency priority.

In NR, many scenarios require supporting the traffic demands of multicasting and broadcasting, such as in the internet of vehicles, industrial internet, etc. It is necessary to introduce MBMS in the NR. There is a need for receiving MBMS service data for UEs in the three RRC states, i.e., idle state, inactive state and connected state. In NR, idle and inactive UEs receive only broadcast type information such as system broadcast and paging in initial BWP. But the bandwidth of the initial BWP is very narrow and is not well suited for transmitting the MBMS service. How to ensure that the UEs in three RRC states normally receive the NR MBMS service data needs to solve the problem of transmission bandwidth resources. For this reason, the following technical solutions of the embodiments of the present application are provided.

In the technical solution of the embodiment of the present application, a new SIB (referred to as a first SIB) is defined, referring to fig. 2, where the first SIB includes configuration information of a first MCCH, where the first MCCH is a control channel of an MBMS service, in other words, the first SIB is used to configure configuration information of a control channel of an NR MBMS, and optionally, the control channel of the NR MBMS may also be referred to as an NR MCCH (i.e. the first MCCH).

Further, the first MCCH is used to carry the first signaling, where the name of the first signaling is not limited, for example, the first signaling is signaling a, and the first signaling includes configuration information of at least one first MTCH, where the first MTCH is a traffic channel (also referred to as a data channel or a transmission channel) of an MBMS service, and the first MTCH is used to transmit MBMS service data (such as service data of NR MBMS). In other words, the first MCCH is used to configure configuration information of a traffic channel of the NR MBMS, alternatively, the traffic channel of the NR MBMS may also be called as NR MTCH (i.e., the first MTCH).

Specifically, the first signaling is used for configuring a service channel of the NR MBMS, service information corresponding to the service channel, and scheduling information corresponding to the service channel. Further optionally, the service information corresponding to the service channel, for example, TMGI, session id, and other identification information for identifying the service. Scheduling information corresponding to the service channel, for example, RNTI used when MBMS service data corresponding to the service channel is scheduled, for example, G-RNTI, DRX configuration information, and the like.

The transmissions of the first MCCH and the first MTCH are scheduled based on the PDCCH. The RNTI used for scheduling the PDCCH of the first MCCH uses a unique network identifier, i.e. a fixed value. The RNTI used for scheduling PDCCH use of the first MTCH is configured through the first MCCH.

It should be noted that, in the embodiment of the present application, the naming of the first SIB, the first MCCH and the first MTCH is not limited. For convenience of description, the first SIB may also be simply referred to as SIB, the first MCCH may also be simply referred to as MCCH, and the first MTCH may also be simply referred to as MTCH, and referring to fig. 3, a PDCCH (i.e. MCCH PDCCH) for scheduling the MCCH and a notification PDCCH are configured through the SIB, where a PDSCH (i.e. MCCH PDSCH) for transmitting the MCCH is scheduled through DCI carried in MCCH PDCCH. Further, M PDCCHs for scheduling MTCH (i.e., MTCH 1 PDCCH, MTCH 2 PDCCH, & gt, MTCH M PDCCH) are configured through the MCCH, wherein DCI carried by MTCH n PDCCH schedules PDSCH for transmitting MTCH n (i.e., MTCH n PDSCH), n being an integer greater than or equal to 1 and less than or equal to M. Referring to fig. 4, MCCH and MTCH are mapped onto DL-SCH, and further, DL-SCH is mapped onto PDSCH, wherein MCCH and MTCH belong to a logical channel, DL-SCH belongs to a transport channel, and PDSCH belongs to a physical channel.

Fig. 5 is a flow chart of a BWP configuration method according to an embodiment of the present application, as shown in fig. 5, where the BWP configuration method includes the following steps:

step 501: the terminal device receives first configuration information for determining a first BWP for receiving the MBMS service.

In the embodiment of the present application, the network device sends first configuration information, and the terminal device receives the first configuration information, where the first configuration information is used to determine a first BWP, and the first BWP is used to receive the MBMS service. Alternatively, the network device may be a base station, such as a gNB.

In the embodiment of the present application, the first BWP may also be referred to as an MBMS BWP, where the MBMS BWP is used for the network device to transmit the MBMS service and for the terminal device to receive the MBMS service.

In the embodiment of the present application, the configuration information of the first BWP (i.e., the first configuration information) may be configured in a system broadcast message or configured in an MCCH. In an alternative embodiment, the first configuration information is configured in a first SIB or a first MCCH. Here, the first SIB is a newly defined SIB, and the first SIB includes configuration information of a first MCCH. The first MCCH is a traffic channel (also referred to as a data channel or a transport channel) of the MBMS service, and is used to configure configuration information of the traffic channel of the NR MBMS.

In an alternative embodiment of the present application, the configuration information of the first BWP (i.e., the first configuration information) includes a time-frequency location, a resource location, a BWP bandwidth, a subcarrier spacing (subcarrier Spacing, SCS), and so on of the first BWP.

In the embodiment of the application, for a terminal device in an idle state or a non-activated state, after the terminal device resides in a first cell, a first SIB is received from the first cell, and the first SIB comprises configuration information of a first MCCH; the terminal equipment acquires the first configuration information from the first SIB; or the terminal equipment acquires the first configuration information from the first MCCH. Here, the terminal device receives the first MCCH based on the first SIB, and then acquires the first configuration information from the first MCCH.

It should be noted that, the description of the first SIB and the first MCCH may be understood with reference to the foregoing scheme. The first cell is a cell where any one of the terminal devices resides. In specific implementation, a first cell broadcasts a first SIB, and after a terminal device resides in the first cell, the first SIB is received from the first cell.

Through the above technical solution of the embodiment of the present application, the concept and configuration of MBMS BWP (i.e., the first BWP) are provided, so that normal reception of MBMS service data by the terminal is ensured.

It should be noted that, the technical solution of the embodiment of the present application may be, but is not limited to, applied to an NR system, and by taking the NR system as an example, the above technical solution realizes that the NR system supports broadcasting and multicasting of MBMS services.

In the embodiment of the application, after the special BWP for the MBMS service, namely the first BWP, is provided, the problem of coexistence of the MBMS service and other service reception needs to be considered, and the normal reception of other services is prevented from being influenced. The following describes how to handle the coexistence of MBMS service with other service reception.

Coexistence between initial BWP and first BWP

For terminal devices in an idle state or inactive state, the terminal devices are configured with an initial BWP for receiving paging and/or system broadcast messages. The first BWP is configured to receive an MBMS service.

Alternatively, the frequency domain location and bandwidth where the first BWP is located may or may not include the initial BWP. In order to realize the coexistence of paging and/or system broadcast messages and the reception of MBMS services, any one of the following schemes may be adopted:

scheme one: the network equipment sends second configuration information, the terminal equipment receives the second configuration information, the second configuration information is used for determining a first time division multiplexing (Time Division Multiplexing, TDM) pattern, and the first TDM pattern is used for determining a receiving position corresponding to the MBMS service; wherein, the receiving position corresponding to the MBMS service is different from the receiving position of the paging and system broadcast message.

Further, the second configuration information includes at least one of:

a first bitmap, wherein each bit in the first bitmap corresponds to a receiving position, and the value of the bit is used for indicating whether the receiving position corresponding to the bit is the receiving position corresponding to the MBMS service;

a period of the first TDM pattern;

offset of the first TDM pattern.

In the above scheme, the receiving position corresponding to the MBMS service is determined by at least one of the following: radio frames, subframes, slots, symbols.

Specifically, a receiving position (such as a receiving radio frame and/or a receiving subframe and/or a receiving time slot and/or a receiving symbol) corresponding to the MBMS service is configured through the first TDM pattern. The receiving location corresponding to the MBMS service should not include paging messages, MIB, RMSI, and OSI receiving locations.

For example: the first bitmap (bitmap) includes N bits, where N is a positive integer, each bit corresponds to a radio frame or subframe or time slot or symbol or a combination thereof, a bit setting of 1 (or 0) indicates that a receiving position corresponding to the bit is a receiving position corresponding to the MBMS service, and a bit setting of 0 (or 1) indicates that the receiving position corresponding to the bit is not a receiving position corresponding to the MBMS service.

The terminal device calculates the receiving position corresponding to the MBMS service based on the second configuration information, where the calculation formula relates to granularity of the receiving position, and uses the subframe as granularity example, and the receiving position can be calculated with reference to the following formula:

SFN mod T＝FLOOR(SubframeOffset/10)

subframe＝SubframeOffset mod 10

wherein subframe offset represents an offset of the first TDM pattern, T represents a period of the first TDM pattern, SFN represents a system frame number corresponding to a reception location, and subframe represents a subframe number corresponding to the reception location.

In an alternative embodiment, the second configuration information is configured in a first SIB or a first MCCH.

Scheme II: the network device sends third configuration information, the terminal device receives the third configuration information, the third configuration information is used for determining a first DRX configuration, the first DRX configuration is used for a first time and a second time, wherein the first time is working time aiming at the MBMS service, and the second time is rest time aiming at the MBMS service.

In the embodiment of the application, the first DRX is configured to determine the first DRX for the MBMS service, the first DRX can also be called as MBMS DRX, and the terminal equipment can monitor paging and system broadcast messages in the rest time of the MBMS DRX.

In an alternative embodiment, the third configuration information is configured in a first SIB or a first MCCH.

Coexistence between dedicated BWP and first BWP

For a terminal device in a connected state, the terminal device is configured with at least one dedicated BWP for transmitting unicast traffic. For example: for terminal devices in a connected state, up to 4 dedicated BWP may be configured, and the switching between the 4 dedicated BWP is based on control signaling (e.g., DCI) at the network side. In order to ensure that the terminal equipment in a connection state does not influence the receiving of the MBMS service while receiving the unicast service on the special BWP, any one of the following schemes can be adopted:

scheme one: the network equipment sends fourth configuration information, the terminal equipment receives the fourth configuration information, the fourth configuration information is used for determining a second TDM pattern, and the second TDM pattern is used for determining a receiving position corresponding to the MBMS service; for a terminal device in a connected state, the terminal device receives an MBMS service at a receiving location corresponding to the MBMS service on the first BWP, and switches from the first BWP to a first dedicated BWP at a time other than the receiving location corresponding to the MBMS service.

Further, the fourth configuration information includes at least one of:

a second bitmap, wherein each bit in the first bitmap corresponds to a receiving position, and the value of the bit is used for indicating whether the receiving position corresponding to the bit is the receiving position corresponding to the MBMS service;

a period of the second TDM pattern;

and an offset of the second TDM pattern.

For example: and configuring a receiving position (such as a receiving radio frame and/or a receiving subframe and/or a receiving time slot and/or a receiving symbol) corresponding to the MBMS service through the second TDM pattern. And the terminal equipment receives the MBMS service at the corresponding receiving position of the MBMS service, and switches from the first BWP to the first special BWP at the time of receiving the non-MBMS service. If the terminal device operates on the first dedicated BWP, the terminal device switches from the master-slave first dedicated BWP to the first BWP to receive the MBMS service when the second TDM pattern indicates the reception time of the MBMS service.

Further, the first dedicated BWP is a dedicated BWP that is last used by the terminal device; or, the first special BWP is a special BWP with the smallest index value in the at least one special BWP; alternatively, the first dedicated BWP is a dedicated BWP having a largest index value among the at least one dedicated BWP.

For example: the second bitmap (bitmap) includes M bits, where M is a positive integer, each bit corresponds to a radio frame or subframe or time slot or symbol or a combination thereof, a bit setting of 1 (or 0) indicates that the receiving position corresponding to the bit is a receiving position corresponding to the MBMS service, and a bit setting of 0 (or 1) indicates that the receiving position corresponding to the bit is not a receiving position corresponding to the MBMS service.

The terminal device calculates the receiving position corresponding to the MBMS service based on the fourth configuration information, where the calculation formula relates to the granularity of the receiving position, and uses the subframe as the granularity example, and the receiving position can be calculated with reference to the following formula:

SFN mod T＝FLOOR(SubframeOffset/10)

subframe＝SubframeOffset mod 10

wherein subframe offset represents an offset of the second TDM pattern, T represents a period of the second TDM pattern, SFN represents a system frame number corresponding to a reception location, and subframe represents a subframe number corresponding to the reception location.

In an alternative embodiment, the fourth configuration information is configured in the first SIB or the first MCCH.

Scheme II: for a terminal device in a connected state, the terminal device receives an MBMS service on a first dedicated BWP.

Here, for the terminal device in the connected state, the terminal device ignores the configuration information of the first BWP and receives the MBMS service on the first dedicated BWP through a unicast manner.

Scheme III: for terminal equipment in a connection state, the terminal equipment receives MBMS service on the first BWP; after receiving the first indication information sent by the network side on the first BWP, the terminal device switches from the first BWP to the first special BWP, and receives the unicast service on the second special BWP and the MBMS service in a unicast manner; after receiving unicast service on the second special BWP, the terminal equipment receives second indication information sent by a network side and switches from the second special BWP to the first BWP based on the second indication information; the terminal device receives the MBMS service on the first BWP.

In an alternative embodiment, the first indication information and the second indication information are sent through a PDCCH.

Specifically, the network side may configure the terminal device to always operate on the first BWP when interested in broadcasting, and when the dedicated BWP has unicast service transmission, the network side sends a PDCCH (i.e. the first indication information) on the first BWP to trigger the terminal device to return to the first dedicated BWP for receiving the unicast service, and the network side also sends the MBMS service to the terminal device in a unicast manner. After the terminal device receives the unicast service, the network side may instruct the terminal device to return to the first BWP through the PDCCH (i.e., the second indication information), and receive the MBMS service on the first BWP, instead of sending the MBMS service to the terminal device on the first dedicated BWP through unicast.
