In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.
With the pursuit of speed, latency, high-speed mobility, energy efficiency and the diversity and complexity of the services in future life, the third generation partnership project (3)rdGeneration Partnership Project, 3GPP) the international organization for standardization began developing 5G. The main application scenarios of 5G are: enhanced mobile ultra-wideband (en)Enhanced Mobile Broadband, eMBB), Low-Latency high-reliability Communications (URLLC), and massive Machine-Type Communications (mMTC).
On the one hand, the eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and the difference between the capabilities and the requirements is relatively large, it cannot be said that it must be analyzed in detail in conjunction with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety, and the like. Typical characteristics of mtc include: high connection density, small data volume, insensitive time delay service, low cost and long service life of the module, etc.

RRC state
5G, in order to reduce air interface signaling, quickly recover wireless connection, and quickly recover data service, a new Radio Resource Control (RRC) state, that is, an RRC INACTIVE (RRC _ INACTIVE) state is defined. This state is distinguished from the RRC IDLE (RRC IDLE) state and the RRC ACTIVE (RRC ACTIVE) state. Wherein the content of the first and second substances,
1) RRC _ IDLE state (IDLE state for short): mobility is UE-based cell selection reselection, paging is initiated by a Core Network (CN), and a paging area is 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 there is a UE context on the base station side and the UE side. The network side knows that the location of the UE is at a specific cell level. Mobility is network side controlled mobility. Unicast data may be transmitted between the UE and the base station.
3) RRC _ INACTIVE state (INACTIVE state for short): mobility is UE-based cell selection reselection, there is a connection between CN-NRs, UE context exists on a certain base station, paging is triggered by RAN, RAN-based paging area is managed by RAN, and network side knows that UE location is based on RAN's paging area level.

BWP
The maximum channel bandwidth in 5G may be 400MHz (i.e., wideband), which is large compared to the maximum channel bandwidth in LTE of 20 MHz. The power consumption of the UE is significant if the UE remains operating on a wideband carrier (i.e., the maximum channel bandwidth). It is proposed that the radio frequency bandwidth of the UE can be adjusted according to the actual throughput of the UE, and for this reason the concept of BWP is introduced, the motivation for which is to optimize the power consumption of the UE. For example, if the rate requirement of the UE is low, the UE may be configured with a smaller bandwidth (i.e., BWP with smaller bandwidth), and if the rate requirement of the UE is high, the UE may be configured with a larger bandwidth (i.e., BWP with larger bandwidth). If the UE supports high rate or operates in Carrier Aggregation (CA) mode, the UE may be configured with multiple BWPs. Furthermore, another purpose of BWP is to trigger coexistence of multiple parameter sets (numerology) in a cell, such as BWP1 for numerology1 and BWP2 for numerology 2.
The UE in an idle state or an inactive state resides on an initial BWP, which is visible to the UE in the idle state or the inactive state, and the UE may obtain Information such as a Master Information Block (MIB), Remaining Minimum System Information (RMSI), Other System Information (OSI), and paging (paging) on the initial BWP.

MBMS
The 3GPP Release 6(Release 6, R6) introduced MBMS, a technology for transmitting data from one data source to a plurality of UEs through shared network resources, which provides multimedia services while efficiently utilizing the network resources to implement broadcast and multicast of higher-rate (e.g., 256kbps) multimedia services.
Since the MBMS spectrum efficiency in 3GPP R6 is low, it is not enough to effectively carry and support the operation of mobile tv type services. Therefore, in LTE, 3GPP explicitly proposes to enhance the support capability for downlink high-speed MBMS services, and determines the design requirements for the physical layer and air interface.
The 3GPP R9 introduces evolved MBMS (eMBMS) into LTE. eMBMS proposes a Single Frequency Network (SFN) concept, that is, a Multimedia Broadcast multicast service Single Frequency Network (MBSFN), where MBSFN employs a uniform Frequency to simultaneously transmit service data in all cells, but needs to ensure synchronization between the cells. The method can greatly improve the distribution of the overall signal-to-noise ratio 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 protocol.
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 the idle-state or connected-state UE.
The 3GPP R13 introduces a Single Cell Point To multipoint (SC-PTM) concept, and SC-PTM is based on the MBMS network architecture.
MBMS introduces new logical channels including a Single Cell-Multicast Control Channel (SC-MCCH) and a Single Cell-Multicast Transport Channel (SC-MTCH). The SC-MCCH and SC-MTCH are mapped to a Downlink-Shared Channel (DL-SCH), and the DL-SCH is further mapped to a 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 (HARQ) operation.
MBMS introduces a new System Information Block (SIB) type, SIB 20. Specifically, the configuration information of the SC-MCCH is transmitted through 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, and the scheduling of the wireless frame and the subframe of the SC-MCCH. Further, 1) the boundary of the modification period of the SC-MCCH satisfies SFN mod m ═ 0, where SFN represents the system frame number of the boundary, and m is the modification period of the SC-MCCH (i.e., SC-MCCH-modification period) configured in SIB 20. 2) And scheduling the radio frame of the SC-MCCH to meet the following requirements: SFN mod MCCH-repetition period ═ MCCH-Offset, where SFN represents the system frame number of a radio frame, MCCH-repetition period represents the repetition period of SC-MCCH, and MCCH-Offset represents the Offset of SC-MCCH. 3) The sub-frame of the SC-MCCH is scheduled and indicated by SC-MCCH-Subframe.
The SC-MCCH is scheduled through a Physical Downlink Control Channel (PDCCH). On one hand, a new Radio Network Temporary Identity (RNTI), that is, a Single Cell RNTI (SC-RNTI) is introduced to identify a PDCCH (e.g., SC-MCCH PDCCH) for scheduling an SC-MCCH, and optionally, the SC-RNTI is fixedly valued as FFFC. On the other hand, a new RNTI, namely a 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, and optionally, the SC-N-RNTI is fixedly valued as FFFB; further, the change notification may be indicated by one bit of 8 bits (bits) of the DCI 1C. In LTE, the configuration information of SC-PTM is based on SC-MCCH configured by SIB20, and then SC-MCCH configures SC-MTCH which is used for transmitting service data.
Specifically, the SC-MCCH transmits only one message (i.e., SCPTMConfiguration) for configuring configuration information of the SC-PTM. The configuration information of SC-PTM includes: temporary Mobile Group Identity (TMGI), session Identity (session id), Group RNTI (G-RNTI), Discontinuous Reception (DRX) configuration information, SC-PTM service information of the neighbor cell, and the like. It should be noted that SC-PTM in R13 does not support Robust Header Compression (ROHC) function.
The downlink discontinuous reception of SC-PTMs is controlled by the following parameters: ondurationTimerSCPTM, drx-InactivetTimeSCPTM, SC-MTCH-SchedulingCycle, and SC-MTCH-SchedulingOffset.
When [ (SFN x 10) + subframe number ] module (SC-MTCH-scheduling cycle) ═ SC-MTCH-scheduling offset is satisfied, starting a timer onDurationTimerSCPTM;
when receiving downlink PDCCH dispatching, starting a timer drx-InactivetyTimerSCPTM;
the downlink SC-PTM service is received only when the timer onDurationTimerSCPTM or drx-inactivityttimerscptm is running.
SC-PTM service continuity adopts the MBMS service continuity concept based on SIB15, namely, SIB15+ MBMSIntestrIndication. The traffic continuity of idle UEs is based on the concept of frequency priority.
In NR, many scenarios need to support multicast and broadcast traffic needs, such as in car networking, industrial internet, etc. It is necessary to introduce MBMS in NR. There is a need for UEs in three RRC states, namely, idle state, inactive state, and connected state to receive MBMS service data. In NR, UEs in idle and inactive states receive only information of broadcast types such as system broadcast and paging in initial BWP. But the bandwidth of the initial BWP is narrow and is not suitable for transmitting MBMS services. Therefore, how to ensure that the UEs in the three RRC states normally receive NR MBMS service data needs to solve the problem of transmission bandwidth resources. Therefore, the following technical scheme of the embodiment of the application is provided.
In the technical solution of the embodiment of the present application, a new SIB (referred to as a first SIB) is defined, and referring to fig. 2, 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 a first signaling, and in this embodiment of the present application, the name of the first signaling is not limited, for example, the first signaling is signaling a, 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 transport channel) of an MBMS service, and the first MTCH is used to transmit MBMS service data (e.g., 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, which may also be called NR MTCH (i.e., the first MTCH) optionally.
Specifically, the first signaling is used to configure 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, the identification information for identifying the service, such as the TMGI, the session id, and the like. 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, for example, G-RNTI, DRX configuration information, and the like.
It should be noted that the transmission of the first MCCH and the first MTCH is scheduled based on the PDCCH. Wherein, the RNTI used by the PDCCH for scheduling the first MCCH uses a network-wide unique identifier, which 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 the embodiment of the present application, 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 abbreviated as SIB, the first MCCH may also be abbreviated as MCCH, and the first MTCH may also be abbreviated as MTCH, and referring to fig. 3, a PDCCH (i.e., MCCH PDCCH) for scheduling MCCH and a notification PDCCH are configured through SIB, wherein a PDSCH (i.e., MCCH PDSCH) for transmitting MCCH is scheduled through DCI carried by MCCH PDCCH. Further, M PDCCHs (i.e., MTCH 1PDCCH, MTCH 2PDCCH, …, MTCH M PDCCH) for scheduling MTCH are configured through the MCCH, wherein DCI carried by the MTCH n PDCCH schedules a PDSCH (i.e., MTCH n PDSCH) for transmitting MTCH n, n being an integer of 1 or more and M or less. Referring to fig. 4, MCCH and MTCH are mapped to DL-SCH, which belong to a logical channel, DL-SCH which belongs to a transport channel, and PDSCH which belongs to a physical channel, and further DL-SCH which is mapped to PDSCH.
Fig. 5 is a flowchart illustrating a BWP configuration method according to an embodiment of the present application, where as shown in fig. 5, the BWP configuration method includes the following steps:
step 501: the terminal equipment receives first configuration information, wherein the first configuration information is used for determining a first BWP, and the first BWP is used for receiving the MBMS service.
In this embodiment of the present application, a network device sends first configuration information, and a 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 an MBMS service. Optionally, the network device may be a base station, for example, a gbb.
In this embodiment of the present application, the first BWP may also be referred to as an MBMS BWP, where the MBMS BWP is used for a network device to transmit an MBMS service and a terminal device to receive the MBMS service.
In this embodiment, the configuration information of the first BWP (i.e., the first configuration information) may be configured in a system broadcast message or configured in the MCCH. In an optional 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 an MBMS service, and the first MCCH is used to configure configuration information of a traffic channel of an NR MBMS.
In an optional embodiment of the present application, the configuration information of the first BWP (i.e., the first configuration information) includes a time-frequency position, a resource position, a BWP bandwidth, a subcarrier Spacing (SCS), and the like of the first BWP.
In the embodiment of the application, for a terminal device in an idle state or an inactive state, after the terminal device resides in a first cell, receiving a first SIB from the first cell, where the first SIB includes configuration information of a first MCCH; the terminal equipment acquires the first configuration information from the first SIB; or, the terminal device 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 schemes. The first cell is a cell where any one terminal device 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, a concept and configuration of an MBMS BWP (i.e. the first BWP) are proposed, thereby ensuring normal reception of MBMS service data by a terminal.
It should be noted that the technical solution of the embodiment of the present application may be, but is not limited to be, applied to an NR system, and the NR system is taken as an example, and the above technical solution implements that the NR system supports broadcast and multicast of an MBMS service.
In the embodiment of the present application, after the dedicated BWP for the MBMS service, such as the first BWP, is proposed, the problem of coexistence of the MBMS service and other services needs to be considered, so as to avoid affecting normal reception of other services. How to handle the coexistence of MBMS service with other service reception is described below.
Figure PCTCN2019106517-APPB-000004
Coexistence between initial BWP and first BWP
For a terminal device in an idle state or an inactive state, the terminal device is configured with an initial BWP, which is used to receive paging and/or system broadcast messages. The first BWP is used for receiving MBMS service.
Optionally, the frequency domain position and bandwidth where the first BWP is located may or may not include the initial BWP. In order to realize the receiving coexistence between the paging and/or system broadcast messages and the MBMS service, any one of the following schemes may be adopted:
the first scheme is as follows: a network device sends second configuration information, and the terminal device receives the second configuration information, where the second configuration information is used to determine a first Time Division Multiplexing (TDM) pattern, and the first TDM pattern is used to determine a receiving position corresponding to the MBMS service; and the receiving position corresponding to the MBMS is different from the receiving position of paging and system broadcast messages.
Further, the second configuration information includes at least one of:
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;
an offset of the first TDM pattern.
In the above solution, the receiving location corresponding to the MBMS service is determined by at least one of: radio frame, subframe, slot, symbol.
Specifically, a receiving location (e.g., a receiving radio frame and/or a receiving subframe and/or a receiving 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 the receiving location of the paging message, MIB, RMSI, and OSI.
For example: the first bitmap (bitmap) comprises N bits, wherein N is a positive integer, each bit corresponds to a radio frame or a subframe or a time slot or a symbol or a combination of the radio frame and the subframe or the time slot and the symbol, the bit is set to be 1 (or 0) to indicate that a receiving position corresponding to the bit is a receiving position corresponding to the MBMS, and the bit is set to be 0 (or 1) to indicate that the receiving position corresponding to the bit is not the receiving position corresponding to the MBMS.
The terminal device calculates the receiving location corresponding to the MBMS service based on the second configuration information, where the calculation formula is related to the granularity of the receiving location, and the receiving location may be calculated with reference to the following formula, for example, by taking the subframe as the granularity:
SFN mod T＝FLOOR(SubframeOffset/10)
subframe＝SubframeOffset mod 10

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, the dedicated BWP being used for transmitting unicast traffic. For example: for a terminal device in a connected state, up to 4 dedicated BWPs can be configured, and the switching between these 4 dedicated BWPs is based on control signaling (e.g., DCI) on the network side. In order to ensure that the connected terminal device does not affect the reception of the MBMS service while receiving the unicast service on the dedicated BWP, any one of the following schemes may be adopted:
the first scheme is as follows: 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; for the terminal equipment in the connected state, the terminal equipment receives the MBMS service on the first BWP at the receiving position corresponding to the MBMS service, and switches from the first BWP to a first dedicated BWP at the time except the receiving position corresponding to the MBMS service.
Further, the fourth configuration information includes at least one of:
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;
an offset of the second TDM pattern.
In the above solution, the receiving location corresponding to the MBMS service is determined by at least one of: radio frame, subframe, slot, symbol.
For example: and configuring a receiving position (such as a receiving wireless frame and/or a receiving subframe and/or a receiving time slot and/or a receiving symbol) corresponding to the MBMS service through a second TDM pattern. And the terminal equipment receives the MBMS at a receiving position corresponding to the MBMS, and autonomously switches from the first BWP to a first dedicated BWP at the time of non-MBMS receiving. If the terminal device operates on the first dedicated BWP, when the second TDM pattern indicates the receiving time of the MBMS service, the terminal device switches from the master-slave first dedicated BWP to the first BWP to receive the MBMS service.
Further, the first dedicated BWP is a dedicated BWP used by the terminal device the last time; or, the first dedicated BWP is a dedicated BWP with a smallest index value among the at least one dedicated BWP; or, the first dedicated BWP is a dedicated BWP with 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 one radio frame, or subframe, or time slot, or symbol, or a combination thereof, bit setting 1 (or 0) indicates that the receiving position corresponding to the bit is a receiving position corresponding to the MBMS service, and bit setting 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 a receiving position corresponding to the MBMS service based on the fourth configuration information, where a calculation formula is related to granularity of the receiving position, and the receiving position may be calculated with reference to the following formula, for example, by taking a subframe as the granularity:
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 the receiving location, and subframe represents a subframe number corresponding to the receiving location.
In an optional embodiment, the fourth configuration information is configured in a first SIB or a 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 a terminal device in a connected state, the terminal device ignores the configuration information of the first BWP and receives the MBMS service on the first dedicated BWP in a unicast manner.
The third scheme is as follows: for a terminal device in a connected state, the terminal device receives an 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 a first dedicated BWP, and receives a unicast service and an MBMS service in a unicast manner on the second dedicated BWP; after the terminal device receives the unicast service on the second private BWP, receiving second indication information sent by the network side, and switching from the second private BWP to the first BWP based on the second indication information; and the terminal equipment receives the MBMS on the first BWP.
In an optional embodiment, the first indication information and the second indication information are transmitted through a PDCCH.
Specifically, the network side may configure the terminal device to always operate on the first BWP when interested in broadcast, 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 instruction 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 in a unicast manner.
