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 wide band (eMBB), Low-Latency high-reliability communication (URLLC), and massive Machine-Type communication (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

In order to reduce air interface signaling, quickly recover wireless connection, and quickly recover data service, 5G defines a new Radio Resource Control (RRC) state, that is, an RRC INACTIVE (RRC _ INACTIVE) state. 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. On the other hand, the purpose of DRX in a wireless communication system is to enable a UE to perform discontinuous traffic reception, thereby achieving power saving. That is, the UE does not need to monitor the service data of the network side all the time, and receives the service data discontinuously according to the information configured by the network. Conventional DRX no longer satisfies the requirement of NR MBMS service reception, so a DRX mechanism needs to be redesigned for discontinuous reception of NR MBMS service. 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 1 PDCCH, MTCH 2 PDCCH, …, 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 DRX configuration method according to an embodiment of the present disclosure, where as shown in fig. 5, the DRX configuration method includes the following steps:

step 501: the terminal equipment receives first configuration information, wherein the first configuration information comprises a first DRX configuration parameter aiming at the MBMS service.

In the embodiment of the application, a network device sends first configuration information, and a terminal device receives the first configuration information, where the first configuration information includes a first DRX configuration parameter for an MBMS service. Optionally, the network device may be a base station, for example, a gbb.

In an optional embodiment of the present application, the first configuration information is configured in a first SIB or a first MCCH. Specifically, the terminal device receives a first SIB, 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 related concepts of the first SIB and the first MCCH can be understood with reference to the related description of the foregoing schemes.

In this embodiment, DRX for the MBMS service in NR may also be referred to as MBMS DRX. Based on this, the first DRX configuration parameter may also be referred to as an MBMS DRX configuration parameter.

Step 502: and the terminal equipment receives the MBMS service based on the first DRX configuration parameter.

In this embodiment of the application, the first DRX configuration parameter includes at least one of: a first timer, a first scheduling period, and a first scheduling offset. Or, the first DRX configuration parameter includes at least one of: the scheduling system comprises a first timer, a first scheduling period, a first scheduling offset and a second timer. The operation mechanism of MBMS DRX is described below in connection with these two cases.

The first DRX configuration parameter includes at least one of: a first timer, a first scheduling period, and a first scheduling offset.

The terminal equipment starts the first timer under the condition that the following conditions are met: [ (system frame number + 10) + subframe number ] mod (first scheduling period) ═ first scheduling offset;

and the terminal equipment receives the MBMS service during the running period of the first timer.

Here, it should be noted that the first timer is started for a time when the system frame number and the subframe number satisfy the above formula.

For example: the first timer is onDurationTimer, the first scheduling period is scheduling cycle, the first scheduling offset is scheduling offset, and based on this, the timer onDurationTimer is started when [ (SFN x 10) + subframe number ] mod (scheduling cycle) ═ scheduling offset is satisfied; the terminal device receives the MBMS service only when the timer onDurationTimer is running. Here, SFN stands for system frame number, subframe number for subframe number, and mod for remainder operation.

In an optional implementation manner, the receiving time of the MBMS service and the receiving time of the scheduling information corresponding to the MBMS service are both located in the running period of the first timer. In a specific implementation, the network side ensures that the time when the terminal device receives the scheduling information and the time when the terminal device receives the corresponding data are both in the running period of the first timer (e.g., onDurationTimer).

The first DRX configuration parameter includes at least one of: the scheduling system comprises a first timer, a first scheduling period, a first scheduling offset and a second timer.

The terminal equipment starts the first timer under the condition that the following conditions are met: [ (system frame number + 10) + subframe number ] mod (first scheduling period) ═ first scheduling offset; the terminal equipment starts the second timer under the condition of receiving a downlink scheduling instruction; and the terminal equipment receives the MBMS service during the operation period of the first timer or the second timer.

Here, it should be noted that the downlink scheduling instruction is carried in the PDCCH.

For example: the first timer is onDurationTimer, the first scheduling period is scheduling cycle, the first scheduling offset is scheduling offset, and the second timer is drx-inactivytytimer, based on which, when [ (SFN x 10) + subframe number ] mod (scheduling cycle) ═ scheduling offset is satisfied, the timer onDurationTimer is started; when terminal equipment receives a downlink scheduling instruction (such as a PDCCH (physical Downlink control channel) for scheduling data transmission), starting a timer drx-InactivetyTimer; the terminal device receives the MBMS service only when the timer onDurationTimer or drx-inactivity timer is running. Here, SFN stands for system frame number, subframe number for subframe number, and mod for remainder operation.

In this embodiment of the present application, the first DRX configuration parameter is used to determine a first time and a second time, where the first time is an operating time for the MBMS service, and the second time is a rest time for the MBMS service.

Based on this, the terminal device switches from the first BWP to the second BWP when the second time arrives; the first BWP is a BWP for the MBMS service, and the second BWP is an initial BWP or a dedicated BWP.

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 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. In an optional embodiment of the present application, the configuration information of the first BWP 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 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. To this end, a Time Division Multiplexing (TDM) pattern is defined, where the TDM pattern is used to determine a receiving location (e.g., receiving a wireless frame and/or a receiving subframe and/or a receiving slot and/or a receiving symbol) corresponding to the MBMS service, a terminal device receives the MBMS service at the receiving location corresponding to the MBMS service on the first BWP, and switches from the first BWP to an initial BWP or a dedicated BWP at a Time other than the receiving location corresponding to the MBMS service.

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 the 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 special BWP to receive the unicast service at the time of non-MBMS receiving.

Further, if the first timer or the second timer is in a running state at the time of BWP switching or within a preset period of time before and after BWP switching, the running of the first timer or the second timer is maintained until the first timer or the second timer times out.

For example: when the time for receiving the non-MBMS service arrives, the terminal device autonomously switches the BWP to the initial BWP or the dedicated BWP to receive data, and keeps the operation of the timer onduration timer or the timer drx inactivity timer until the time-out, regardless of whether the timer onduration timer or the timer drx inactivity timer is running. If the timer onDurationTimer or the timer drx-inactivytytytimer is still running after the terminal device switches the BWP back to the first BWP (i.e., MBMS BWP), the running of the timer is continuously maintained until the timeout.
