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.
At early deployment of NRs, full NR coverage is difficult to acquire, so typical network coverage is wide area LTE coverage and island coverage mode of NRs. And a large amount of LTE is deployed below 6GHz, and the frequency spectrum below 6GHz which can be used for 5G is few. NR must study spectral applications above 6GHz while high-band coverage is limited and signal fading is fast. Meanwhile, in order to protect the mobile operators from early investment in LTE, a working mode of tight coupling (tight interworking) between LTE and NR is proposed.
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,
1) Rrc_idle state (simply referred to as IDLE state): mobility is cell selection reselection based on terminal equipment, paging is initiated by a Core Network (CN), and paging areas are configured by the CN. The base station side has no terminal equipment context and no RRC connection.
2) Rrc_connected state (CONNECTED state for short): there is an RRC connection and there is a terminal device context at the base station side and the terminal device side. The network side knows that the location of the terminal device is cell specific. Mobility is network-side controlled mobility. Unicast data may be transmitted between the terminal device and the base station.
3) Rrc_inactive state (simply referred to as INACTIVE state): mobility is cell selection reselection based on terminal equipment, connection between CN-NR exists, terminal equipment context exists on a certain base station, paging is triggered by RAN, paging area based on RAN is managed by RAN, network side knows that the position of terminal equipment is based on paging area level of RAN.
MBMS
MBMS is a technology for transmitting data from one data source to a plurality of terminal equipments through a shared network resource, which can effectively utilize the network resource while providing a multimedia service, and realize broadcasting and multicasting of a multimedia service of a higher rate (e.g., 256 kbps).
Due to the low MBMS spectrum efficiency, 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 terminal devices 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: onDurationTimerSCPTM, drx-InactivityTimerSCPTM, 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 the terminal device 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 (referred to as a first SIB) is defined, 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 a PDCCH (i.e. MCCH PDCCH) for scheduling the MCCH and a notification PDCCH are configured through 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, …, 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. The MCCH and the MTCH are mapped to the DL-SCH, and further, the DL-SCH is mapped to the PDSCH, wherein the MCCH and the MTCH belong to a logical channel, the DL-SCH belongs to a transport channel, and the PDSCH belongs to a physical channel.
It should be noted that, although the above scheme is described by taking MBMS as an example, the description of "MBMS" may be replaced by "MBS". The embodiment of the application is illustrated by taking MBS as an example, and the description of the MBS service can be replaced by MBMS.
In the NR MBS, as shown in fig. 2, a 5G core network transfers MBS traffic To a 5G access network (such as a gNB) through a shared GTP tunnel, and the 5G access network may determine To transfer MBS traffic To a terminal device in a Point-To-Point (PTP) manner or in a Point-To-multipoint (Point To Multipoint, PTM) manner.
For terminal devices receiving MBS services, other non-MBS services, such as an eMBB service, are also received. The terminal device can be released to an idle state or an inactive state or kept in a connected state by the network side when there is no MBS service transmission. When the terminal equipment is in idle state or inactive state, the network side can wake up the terminal equipment by paging to receive MBS service when the data of the MBS service arrives.
In NR, paging of multiple users corresponding to the same Paging Occasion (PO) may be multiplexed in one Paging message, so that multiple users corresponding to one PO may monitor Paging messages of MBS service, and even if some users do not participate in the MBS service, paging messages of MBS service may wake up those users, which may affect those users, for example, cause electricity consumption of those users. In addition, NR supports beam scanning (beam scanning) transmission, so that one paging message may be transmitted in one cell, and the specific number of parts depends on the number of Synchronization Signal Blocks (SSBs) actually transmitted by the cell, so that the paging message of the MBS service may have a high load, and wireless resources are wasted. For this reason, the following technical solutions of the embodiments of the present application are provided.
Fig. 3 is a flow chart of a method for indicating paging according to an embodiment of the present application, as shown in fig. 3, the method for indicating paging includes the following steps:
step 301: the network equipment sends first DCI, the terminal equipment receives the first DCI, the first DCI is used for scheduling paging information, wherein the first DCI carries first indication information, and the first indication information is used for indicating at least one of the following: the paging message is an MBS paging message; triggering the MBS service information of the paging message.

In the embodiment of the present application, a network device sends a first DCI, and a terminal device receives the first DCI, specifically, the terminal device monitors and receives the first DCI in a PO.
In this embodiment of the present application, the first DCI carries scheduling information of a paging message, in other words, the first DCI is used to schedule the paging message. In some alternative embodiments, the first DCI may also be referred to as paging DCI (paging DCI).

For a terminal device, in some optional embodiments, if the terminal device is a legacy (legacy) type terminal device or a terminal device that is not configured with an MBS service, the terminal device discards receiving the paging message of the first DCI schedule; or if the terminal equipment is configured with or supports the MBS service, the terminal equipment receives the paging message scheduled by the first DCI.
Here, the paging message scheduled by the first DCI is received, which may also be understood as receiving a PDSCH scheduled by the first DCI, where the PDSCH is used to carry the paging message.
Here, the legacy (legacy) type terminal device refers to a terminal device of a non-MBS service (i.e., a terminal device that does not receive the MSB service), for example, an eMBB type terminal device.
As an example, the first indication information is 1-bit information, the value of the 1-bit information is a first value for indicating that the paging message is an MBS paging message, and the value of the 1-bit information is a second value for indicating that the paging message is not an MBS paging message. Here, the first value is 1, and the second value is 0; alternatively, the first value is 0 and the second value is 1.

Here, optionally, the information of the MBS service triggering the paging message includes at least one of: MBS service identification and MBS service association information.
In some optional embodiments, the first indication information is used to indicate an MBS service identifier of an MBS service that triggers the paging message. As an example, the MBS service identifier includes at least one of: TMGI, G-RNTI, MBS session identification.
For the terminal device, in some optional embodiments, if the terminal device is a legacy type terminal device or a terminal device that is not configured with an MBS service corresponding to the MBS service identifier, the terminal device discards receiving the paging message of the first DCI schedule.
For the terminal device, in some optional embodiments, if the MBS service corresponding to the MBS service identifier is an MBS service of interest to the terminal device or a joining MBS service or an MBS service desired to be received, then:
option 1: the terminal equipment receives the paging message scheduled by the first DCI; or,
Option 2: and the terminal equipment directly initiates a Radio Resource Control (RRC) connection establishment process or an RRC connection recovery process without receiving the paging message scheduled by the first DCI.
Here, the paging message scheduled by the first DCI is received, which may also be understood as receiving a PDSCH scheduled by the first DCI, where the PDSCH is used to carry the paging message.
Here, the legacy type terminal device refers to a terminal device other than the MBS service (i.e., a terminal device that does not receive the MSB service), for example, an eMBB type terminal device.
In some optional embodiments, the first indication information is used to indicate MBS service association information. Wherein, the MBS service association information comprises at least one of the following: the type of MBS service; and the first information of the MBS service is obtained based on the MBS service identification.
As an example, the first information of the MBS service may be a part of content of an MBS service identity.
As an example, the first information of the MBS service may be calculated by MBS service identification, taking the MBS service identification as TMGI as an example, where k is a positive integer.
For a terminal device, in some optional embodiments, the terminal device determines whether the paging message is a paging message of its own based on the MBS service association information; if the terminal equipment determines that the paging message is not the paging message of the terminal equipment, the terminal equipment gives up receiving the paging message scheduled by the first DCI; or if the terminal equipment determines that the paging message is the paging message of the terminal equipment, the terminal equipment receives the paging message scheduled by the first DCI.
Here, the capacity (or occupied load) of the MBS service association information is small, so that overhead of the first DCI may be effectively saved. The terminal equipment can judge the probability that the paging message is the paging message of the terminal equipment according to the MBS service association information, if the probability is larger (for example, the probability is larger than or equal to a specified threshold value), the terminal equipment receives the paging message scheduled by the first DCI, and further judges whether the paging message is the paging message of the terminal equipment or not through the paging message; if the probability is small (e.g., less than or equal to a specified threshold), the reception of the paging message of the first DCI schedule is aborted.
In some optional embodiments, the first DCI further carries a first information field, where the first information field can be parsed by a legacy type terminal device; and under the condition that the value of the first information field is a specific value, the terminal equipment of the traditional type does not receive the paging message scheduled by the first DCI.
As an example, the first information field is a short message indication (short message indicator) information field. Here, the short message indication information field occupies 2 bits. After receiving the first DCI, the terminal device of the conventional type parses 2 bits in the short message indication information field, and if the value of the 2 bits is a specific value, for example, 00 or 10, the terminal device of the conventional type does not receive the paging message scheduled by the first DCI. Optionally, the terminal device of the conventional type does not parse the first indication information.
According to the technical scheme, the first DCI used for scheduling the paging message carries the first indication information, and the first indication information is used for indicating that the paging message is the MBS paging message and/or the MBS service information triggering the paging message, so that the terminal equipment can determine whether to monitor the paging message according to the situation of the terminal equipment, the influence of MBS paging on the terminal equipment which does not participate in the MBS service is reduced, on one hand, the load of air interface signaling is reduced, and on the other hand, the purpose of saving electricity of the terminal equipment is achieved.
