In order to facilitate understanding of the technical solution of the embodiments of the present application, the technical solution of the present application is described in detail below through specific embodiments. The following related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

Currently, with the pursuit of speed, delay, high-speed mobility, energy efficiency and the diversity and complexity of future life services, 5G communication networks are introduced. The main application scenario of 5G is: enhanced mobile Ultra-wideband (Enhance Mobile Broadband, eMBB), low latency high reliability communications (Ultra-Reliable and Low Latency Communication, URLLC), large scale machine type communications (MASSIVE MACHINE TYPE of communications, mMTC).

EMBB still aims at obtaining multimedia content, services and data by users, and the demand of which is growing very rapidly. On the other hand, eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., where the capability and demand are also quite different, so detailed analysis must be performed in conjunction with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical features of mMTC include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

The NR may also be deployed independently, and a new radio resource control (Radio Resource Control, RRC) state, i.e., rrc_inactive state, is introduced in the 5G network environment for the purposes of reducing air interface signaling and fast recovery of radio connections, and fast recovery of data traffic. The rrc_inactive state is different from the RRC IDLE (rrc_idle) state and the RRC ACTIVE (rrc_active) state.

Rrc_idle: mobility is terminal-based cell selection reselection, paging is initiated by a Core Network (CN), and paging areas are configured by the CN. The base station side does not have Access Stratum (AS) context of the terminal. There is no RRC connection.

Rrc_connected: there is an RRC connection and the base station and the terminal have an AS context for the terminal. The network side knows that the location of the terminal is cell specific. Mobility is network-side controlled mobility. Unicast data may be transmitted between the terminal and the base station.

Rrc_inactive: mobility is terminal-based cell selection reselection, there is a connection between the core network and the NR (CN-NR), the AS context of the terminal is present on a certain base station, paging is triggered by the radio access network (Radio Access Network, RAN), the RAN-based paging area is managed by the RAN, and the network side knows that the location of the terminal is based on the RAN paging area level.

In 5G, the maximum channel bandwidth may be 400MHz (e.g., wideband carrier), which is large compared to the maximum 20M bandwidth of LTE. If the terminal device remains operating on the broadband carrier, the power consumption of the terminal device is significant. Thus, the Radio Frequency (RF) bandwidth of the terminal device may be adjusted according to the actual throughput of the terminal device. And introduces a bandwidth part (Band WIDTH PART, BWP) to optimize the power consumption of the terminal device. For example, the rate of the terminal device is low, a smaller bandwidth may be configured for the terminal device (as shown in (a) of fig. 2), and if the rate requirement of the terminal device is high, a larger bandwidth may be configured for the terminal device (as shown in (b) of fig. 2). If the terminal device supports a high rate or operates in a carrier aggregation (Carrier Aggregation, CA) mode, the terminal device may be configured with a plurality of BWPs (as shown in (c) of fig. 2). Another purpose of BWP is to trigger coexistence of multiple basic parameter sets (numerology) in one cell.

In some embodiments, terminals in the RRC idle state or RRC deactivated state reside on an initial (initial) BWP, which is visible to terminals in the RRC idle state or RRC deactivated state, within which a master Information block (Master Information Block, MIB), remaining system Information (REMAINING SYSTEM Information, RMSI), other system Information (Other System Information, OSI), padding, and the like may be acquired.

For better understanding of the embodiments of the present application, MBMS and SC-PTM systems in LTE related to the present application are described.

Multimedia broadcast multicast service (Multimedia Broadcast Multicast Service, MBMS) is a technology for transmitting data from one data source to a plurality of user equipments through a shared network resource, and can effectively utilize the network resource while providing multimedia services, realizing broadcasting and multicasting of multimedia services at a higher rate (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. Enhanced MBMS (E-MBMS) introduces the concept of a single frequency network (Single Frequency Network, SFN), i.e. transmitting data simultaneously in all cells using a unified frequency, but ensuring synchronization between cells. 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. And implements broadcast and multicast of services based on an internet protocol (Internet Protocol, IP) multicast protocol.

In LTE/LTE-a, MBMS has only a broadcast bearer mode and no multicast bearer mode.

The reception of the MBMS service is applicable to UEs in an RRC connected state or an RRC idle state.

The single cell point-to-multipoint transmission (SINGLE CELL Point To Multipoint, SC-PTM) is based on the MBMS network architecture, and the Multi-cell/multicast coordination unit (Multi-cell/multicast Coordination Entity, MCE) decides whether to employ the SC-PTM transmission scheme or the multimedia broadcast multicast service single frequency network (Multimedia Broadcast multicast SERVICE SINGLE Frequency Network, MBSFN) transmission scheme.

Specifically, as shown in fig. 3, SC-PTM introduces a single cell multicast control channel (SINGLE CELL Multicast Control Channel, SC-MCCH) and a single cell multicast transport channel (SINGLE CELL Multicast Transport Channel, SC-MTCH), logical channel identification (Logical CHANNEL IDENTITY, LCID) of SC-mcch=11001, lcid=11001 of SC-MTCH. The SC-MCCH and SC-MCCH may be mapped to a Downlink shared channel (Downlink SHARED CHANNEL, DL-SCH) transport channel, a physical Downlink shared channel (Physical Downlink SHARED CHANNEL, PDSCH) physical channel. The SC-MCCH and SC-MTCH do not support hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) operations.

The SC-PTM introduces a new system information block (System Information Block, SIB) type, SIB20 to transmit configuration information of the SC-MCCH, and one cell has only one SC-MCCH. The configuration information includes: modification period, repetition period, and radio frame and subframe configuration information of the SC-MCCH.

Radio frame scheduled by SC-MCCH: system Frame Number (SFN) mod MCCH repetition period (MCCH-RepetitionPeriod) =mcch Offset (MCCH-Offset).

The subframes of the SC-MCCH schedule are indicated by an SC-MCCH Subframe (SC-MCCH-Subframe) field.

The SC-MCCH transmits only one message SC-PTM configuration (SC-PTMConfiguration) for configuring configuration information of the SC-PTM. A new radio network temporary identity (Radio Network Temporary Identity, RNTI), single cell RNTI (SINGLE CELL RNTI, SC-RNTI) (fixed value FFFC) is introduced to identify scheduling information of the SC-MCCH on the physical downlink control channel (Physical Downlink Control Channel, PDCCH).

The SC-PTM introduces a new RNTI, a single cell Notification RNTI (SINGLE CELL Notification RNTI, SC-N-RNTI) (fixed value FFFB), and identifies the PDCCH of the SC-MCCH change Notification. The change notification is indicated by one bit of 8 bits (bits) in a downlink control information Format (Downlink Control Information Format, DCI Format) 1C. The modification period boundary is defined as SFN mod m=0, where m is the modification period (sc-mcch-ModificationPeriod) configured in SIB 20.

In NR, the radio link control (Radio Link Control, RLC) acknowledged mode (Acknowledged Mode, AM) mode is with automatic repeat request (Automatic Repeat reQuest, ARQ) feedback mechanism. The receiving end transmits an RLC status report to feedback whether the reception status of the RLC packet is an Acknowledgement (ACK) or a negative Acknowledgement (Negative Acknowledgement, NACK). The transmitting end may repeatedly transmit the RLC packet of the Sequence Number (SN) number of the feedback NACK.

For better understanding of the embodiments of the present application, the downlink BWP configuration related to the present application is described.

The Downlink BWP is configured by a BWP-Downlink parameter, as shown in the following first-segment asn.1 code, and the parameter includes an identifier (Id) for BWP-Id field identifying the current BWP, BWP-Common is used to configure a Common parameter of the Downlink BWP, as shown in the following second-segment asn.1 code, where GENERICPARAMETERS in BWP-DownlinkCommon is used to configure a frequency domain starting point of the Downlink BWP and the number of physical resource blocks (physical resource block, PRBs) included. For a terminal-specific unicast BWP, the BWP-decoded parameter in BWP-Downlink will configure the Downlink reception parameter on the Downlink BWP, which as shown in the following third-segment asn.1 code, at least includes PDCCH-Config, PDSCH-Config, and SPS-Config, and the second-segment asn.1 code, where PDCCH-Config is used to indicate the PDCCH transmission mode on the Downlink BWP, PDSCH-Config is used to indicate the PDSCH transmission mode on the Downlink BWP, and SPS-Config is used to indicate the Semi-persistent scheduling (Semi-PERSISTENT SCHEDULING, SPS) configuration on the Downlink BWP.

In order to better understand the embodiments of the present application, the propagation mode of the NR MBS related to the present application will be described.

For MBS services, the manner in which the base station schedules transmissions is as follows:

Broadcast (Broadcast): the MBS service is sent in a broadcast mode, and is suitable for the terminal to be in an RRC_IDLE/RRC_INACTIVE state and the terminal equipment to be in an RRC_CONNECTED state. That is, through the MBS service transmitted by broadcasting, the terminal is in any link state as long as it can receive the same within the coverage area.

Multicast/Multicast (Multicast): and the base station sends the same MBS service to a group of terminals by a one-to-many PTM sending mode.

Unicast (Unicast): and the base station sends the same MBS service to each terminal by a one-to-one PTP sending mode.

For better understanding of the embodiments of the present application, descriptions are given to the NR MBS group scheduling method related to the present application.

In NR MBS, one-to-many multicast transmission needs to be supported, in this transmission mode, the base station needs to schedule a common PDSCH by sending a common downlink control channel, where the common PDCCH and the common PDSCH are sent in a section of common frequency domain resource (Common Frequency Resource, CFR). In some embodiments, there are two alternative CFR configurations:

First kind: the CFR is configured as an MBS-specific BWP, which is associated with a terminal-specific unicast BWP, and the subcarrier spacing and cyclic prefix configured on the CFR are the same as those on the terminal-specific unicast BWP.

Second kind: the CFR is configured as a plurality of PRBs that are contiguous in the terminal-specific unicast BWP range.

The first approach has the advantage that the CFR can follow the BWP signaling configuration, which is advantageous for reducing the standard workload, but has the problem that, since the CFR is defined as BWP, if the terminal is required to receive unicast in dedicated unicast BWP and multicast in CFR at the same time, meaning that the terminal needs to receive downlink transmission on two BWP simultaneously, the terminal is however only capable of receiving downlink on one BWP at a given moment, and in addition, even if the terminal receives unicast and multicast at different times, BWP handover delay is introduced because both are located in different BWP. The second method can avoid the problem of BWP handover, but in this method, since the CFR is a plurality of consecutive PRBs, the existing BWP-based signaling configuration cannot be used, and the resource range of the CFR, the configuration mode of uplink and downlink transmission parameters, and the like need to be redesigned, which has a large impact on the standard.

In addition, since the common PDCCH scheduling the common PDSCH needs to be simultaneously transmitted to a plurality of receiving terminals, in order to ensure that the number of bits of common downlink control information (Downlink Control Information, DCI) carried in the common PDCCH determined by the plurality of terminals is the same, the terminal cannot determine the number of bits of the common DCI according to the configuration of the respective dedicated unicast BWP, and in addition, since the number of PRBs of the CFR may be different from the initial BWP or control resource set #0 (Control Resource Set 0, coreset # 0) currently configured by the terminal, the terminal cannot determine the number of bits of the common DCI through the initial BWP or CORESET #0. Therefore, it is inevitable that the number of bits of the Common DCI may be different from the number of DCI bits received by the terminal in the terminal device specific search space (UE SEARCH SPACE, USS) or the Common search space (Common SEARCH SPACE, CSS). Then, in order to reduce the implementation complexity of the terminal, the terminal can only receive DCI with 4 different bit numbers at most in one cell, wherein the bit number of DCI scrambled by a cell radio network temporary identifier (Cell Radio Network Temporary Identity, C-RNTI) is not more than 3.

In some embodiments, as shown in fig. 4, there may be three ways of scheduling transmission of MBS services, in which PTM1 and Point-to-Point (PTP) are already supported. A group shared PDCCH (GC-PDCCH) or a group shared PDSCH (GC-PDSCH) refers to a PDCCH/PDSCH transmitted by a base station on a set of time-frequency resources that can be received by multiple UEs of the same group. The Point-to-multipoint-Point (PTM) scheduling modes mentioned in this scheme are all referred to as PTM1.

PTM 1: for multiple UEs of the same group in a connected state, a group shared PDCCH (GC-PDCCH) is used to schedule a group shared PDSCH (GC-PDSCH), wherein a cyclic redundancy check (Cyclical Redundancy Check, CRC) of the group shared PDCCH (GC-PDCCH) is scrambled using a group shared RNTI (G-RNTI), and the group shared PDSCH (GC-PDSCH) is scrambled using the same group shared RNTI (G-RNTI).

PTM 2: for multiple UEs of the same group in a connected state, a group shared PDSCH (GC-PDSCH) is scheduled for each UE using a UE-specific PDCCH, wherein the CRC of the UE-specific PDCCH is scrambled using a UE-specific RNTI (i.e., C-RNTI), and the group shared PDSCH (GC-PDSCH) is scrambled using a group shared RNTI (G-RNTI).

PTP: for connected UEs, a UE-specific PDCCH is used to schedule a UE-specific PDSCH for each UE, wherein the CRC of the UE-specific PDCCH is scrambled using a UE-specific RNTI (i.e., C-RNTI) and the UE-specific PDSCH is scrambled using a UE-specific RNTI (i.e., C-RNTI).

In some embodiments, the retransmission mechanism of MBS service based on hybrid automatic repeat request-acknowledgement (Hybrid Automatic Repeat request Acknowledgement, HARQ-ACK) feedback in connection state supports several ways as follows:

mode one: primary transmission PTM1+retransmission PTM1;

mode two: the PTM1+ retransmission PTP is initially transmitted.

For better understanding of the embodiments of the present application, the manner in which HARQ Process IDs (HPIDs) are used for NR MBS multicast and unicast related to the present application will be described.

HPID (HARQ process ID: 0-15) sharing the system between multicast/multicast and unicast, how HPID is specifically allocated is determined by the base station implementation.

HPID and the new data indication (New Data Indicator, NDI) together determine whether a currently transmitted transport block (Transmission block, TB) is an initial transmission or a retransmission. For example, currently received HPID #1 corresponds to ndi=0 carried in DCI.

Comparing ndi=1 corresponding to HPID #1 received immediately before, and determining the currently received TB as an initial transmission of a new TB; the UE empties the data information of the last TB stored in the buffer, and then stores the initial transmission of the newly received TB and the potentially received retransmission in the buffer for soft combining.

The currently received TB may be determined to be retransmitted at this time by comparing ndi=0 corresponding to HPID #1 received previously.

In order to facilitate better understanding of the embodiments of the present application, the technical problems to be solved by the present application will be described.

For SPS PDSCH of unicast service, the technical schemes of SPS activation (activation) and deactivation (deactivation) are as follows:

the CRC of DCI is scrambled by CS-RNTI to indicate activation and deactivation of SPS configuration (SPS configuration).

Activating: a single DCI activates a single SPS configuration at a time, and the HPN information field in the DCI indicates the SPS configuration index to be activated.

Deactivation: a) A single DCI may deactivate a single SPS configuration at a time, a hybrid automatic repeat request process number (Hybrid Automatic Repeat request process number, HPN) information field in the DCI indicating an SPS configuration index to be deactivated; b) Multiple SPS configurations can be deactivated at a time by a single DCI, and the higher layer configures the list of deactivation status lists (SPS-ConfigDeactivationStateList) by configuration parameters SPS, each row of the list corresponds to a list index value, each index value corresponds to one or more SPS configuration indexes, and the HPN information field in the DCI indicates a list index value and corresponds to deactivating one or more SPS configuration indexes corresponding to the list index value.

The SPS configuration supported by the unicast service is 8 at most, and the SPS configuration index is represented by 0-7;

The HPN information field in DCI is 4 bits long, and the first 8bits (i.e., 0000-0111) are used to indicate the SPS configuration index or list index to which activation/deactivation corresponds.

The CRC of the group shared DCI is scrambled by a group pre-configured scheduling radio network temporary identity (Group Configured Scheduling Radio Network Temporary Identity, G-CS-RNTI) for indicating activation or deactivation of SPS configuration common to a group of terminals.

Activating: a single group shared DCI activating a single SPS configuration for a group of UEs at a time, an HPN information field in the DCI indicating an SPS configuration index to activate;

Deactivation: a) A single group shared DCI may deactivate a single SPS configuration of a group of UEs at a time, an HPN information field in the DCI indicating an SPS configuration index to be deactivated; b) A single UE-specific DCI (CRC scrambled with a pre-configured scheduling radio network temporary identity (Configured Scheduling Radio Network Temporary Identity, CS-RNTI)) may deactivate a single SPS configuration of one UE at a time, the HPN information field in the DCI indicating the SPS configuration index to be deactivated; c) A single set of shared DCI may deactivate multiple SPS configurations for a set of UEs at a time; or a single UE-specific DCI may deactivate multiple SPS configurations for one UE at a time.

The SPS configuration supported by MBS service is 8 at most, and the SPS configuration index is undetermined; the HPN information field in the DCI is 4 bits long, which status bits are used to indicate that the SPS configuration index or list index corresponding to activation/deactivation is not specified.

Considering the SPS configuration design when the system has only unicast service, when the system supports SPS configuration of MBS service, the unicast service and SPS of MBS service coexist, which can generate a series of problems, and the following problems are not solved yet.

When the terminal-specific DCI is used for deactivating SPS configuration, the terminal cannot distinguish the SPS of the unicast service or the SPS configuration of the MBS service when the DCI is deactivated because the CRC of the DCI adopts CS-RNTI scrambling, and because only the HPN information field is used for indicating the corresponding SPS configuration index in the DCI, no other information is used for indicating the distinction between the unicast service and the MBS service.

The SPS configuration index for MBS services has not been determined, and 0-7 is used to represent the SPS configuration index, or other numerical representation.

How to map the correspondence between bit status bits in the HPN information domain and MBS SPS configuration indexes.

How to design an SPS configuration list configuring MBS services, multiple SPS configurations can be deactivated using a single DCI, and it is possible to distinguish which SPS configurations belong to the unicast service and which SPS configurations belong to the MBS services from these deactivated SPS configuration indexes.

Based on the technical problems, the application provides a scheme for activating or deactivating SPS configuration, a communication system can simultaneously support SPS configuration associated with unicast service and SPS configuration associated with MBS service to work simultaneously, and the SPS configuration associated with unicast service and the SPS configuration associated with MBS service have no limit or influence on each other, and furthermore, the SPS configuration associated with unicast service and the SPS configuration associated with MBS service can work cooperatively, so that the compatibility performance of the communication system is improved.
