The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 can be distributed in the cell managed by each access network device 20. The terminal device can also be referred to simply as a terminal device or a UE, and those skilled in the art can understand its meaning.

[0035] The access network device 20 is a device deployed in an access network to provide wireless communication functions for the terminal device 10. The access network device 20 can include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different wireless access technologies, the names of devices with access network device functions can be different, for example, in a 5G NR system, it is called gNodeB or gNB. As communication technology evolves, the name of the "access network device" may change. For ease of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as access network devices. In some embodiments, through the access network device 20, a communication relationship can be established between the terminal device 10 and the core network element 30. Illustratively, in the LTE (Long Term Evolution) system, the access network device 20 can be an EUTRAN (Evolved Universal Terrestrial Radio Access Network) or one or more eNodeBs in the EUTRAN; in the 5G NR system, the access network device 20 can be a RAN (Radio Access Network) or one or more gNBs in the RAN. In the embodiments of the present application, the "network device" refers to the access network device 20, such as a base station, unless otherwise specified.

[0036] The core network element 30 is a network element deployed in the core network, and the main function of the core network element 30 is to provide user connection, management of users, and completion of bearer for services, and to provide an interface to external network devices as a bearer network device. For example, the core network element in the 5G NR system can include an AMF (Access and Mobility Management Function) entity, a UPF (User Plane Function) entity, and an SMF (Session Management Function) entity, and the like.

[0037] In some embodiments, the access network device 20 and the core network element 30 communicate with each other through some air interface technology, such as the NG interface in the 5G NR system. The access network device 20 and the terminal device 10 communicate with each other through some air interface technology, such as the Uu interface.

[0038] The "5G NR system" in the embodiments of the present application can also be referred to as a 5G system or an NR system, but those skilled in the art can understand its meaning. The technical solutions described in the embodiments of the present application can be applicable to an LTE system, a 5G NR system, an evolved system (such as a B5G (Beyound 5G) system, a 6G system (6th Generation System, the sixth generation mobile communication system)) after the 5G NR system, and other communication systems such as an NB-IoT (Narrow Band Internet of Things, narrowband Internet of Things) system, and the present application does not limit this.

The cell can be a cell corresponding to the network device (for example, a base station), and the cell can belong to a macro base station or a base station corresponding to a small cell (Small cell). The small cell can include a metro cell, a micro cell, a pico cell, a femto cell, and the like. These small cells have the characteristics of small coverage and low transmit power, and are suitable for providing high-speed data transmission services.

[0040] Before introducing the technical solutions of the present application, the related technologies involved in the present application are introduced and explained. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, and all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0041] 1.5G main application scenarios and RRC (Radio Resource Control, Radio Resource Control) state

[0042] Currently, with the pursuit of rate, delay, high mobility, and energy efficiency, and the improvement of the diversity and complexity of future life services, the 3GPP international standard organization has begun to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (enhanced Mobile BroadBand, eMBB), low latency and high reliability communication (Ultra Reliable & LowLatency Communication, URLLC), and massive machine type communication (massive Machine Type of Communication, mMTC).

[0043] NR can also be deployed independently, in order to reduce air interface signaling and quickly recover wireless connection in 5G network device environment, a new RRC state, RRC_INACTIVE (RRC inactive state) state is defined for the purpose of quickly recovering data services. This state is different from RRC_IDLE (RRC idle state) and RRC_ACTIVE (RRC active state).

[0044] RRC_IDLE: mobility is based on UE's cell selection reselection, paging is initiated by CN (Core Network), and paging area is configured by CN. There is no UE AS (Access Stratum) context on the base station side. There is no RRC connection.

[0045] RRC_CONNECTED: there is an RRC connection, and there is a UE AS context between the base station and the UE. The network device side knows the UE's location is specific to the cell level. Mobility is network device side controlled mobility. Unicast data can be transmitted between the UE and the base station.

[0046] RRC_INACTIVE: mobility is based on UE's cell selection reselection, there is a connection between CN and NR, UE AS context exists on a certain base station, paging is triggered by RAN (Radio Access Network), RAN-based paging area is managed by RAN, and the network device side knows the UE's location is based on the RAN-based paging area level.

[0047] 2.5G NR paging mechanism

[0048] The main function of paging is to enable the network device to page the UE through the paging message in the RRC IDLE or RRC INACTIVE state of the UE, or to notify the UE of system message changes or earthquake tsunami / public warning information (applicable to all RRC states of the UE, including the connected state) through a short message.

[0049] Paging includes PDCCH scrambled by P-RNTI (Paging Radio Network Temporary Identifier), and PDSCH scheduled by the PDCCH. The paging message is transmitted in the PDSCH, and the short message is 8 bits in the PDCCH (Physical Downlink Control Channel).

[0050] For a UE in RRC_IDLE or RRC_INACTIVE state, since there is no other data communication between the UE and the network device, in order to save power of the terminal device, the UE can discontinuously listen to the paging channel, that is, a paging DRX (Discontinuous Reception) mechanism is adopted. Under the paging DRX mechanism, the UE only needs to listen to the paging during a PO (Paging Occasion) in each DRX cycle period. It is stipulated in TS 38.304 that the PO is composed of a plurality of PDCCH monitoring occasions on the paging search space, and one PO contains X PDCCH monitoring occasions, X being equal to the actual number of SSBs (Synchronization Signal Blocks) transmitted in the MIB (Master Information Block) broadcast. In addition, there is a concept of Paging Frame (PF), which refers to a radio frame (fixed 10 ms) that can contain a plurality of POs or the starting position of a plurality of POs.

[0051] The period of the paging DRX is determined by the common period in the system broadcast and the dedicated period configured in the high-layer signaling (NAS (Non-Access Stratum) signaling), and the UE takes the minimum period of the two as the period of the paging cycle. From the perspective of the network device, one paging DRX cycle can have a plurality of POs, and the position of the UE listening to the PO is related to the ID (Identity Document) of the UE. The specific determination method of a certain UE in a PF and a PO in a paging DRX cycle is as follows (TS 38.304):

[0052] The SFN (System Frame Number) number of the PF is determined by the following formula:

[0053] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N)

[0054] The number Index (i_s) of the PO in a PF is determined by the following formula:

[0055] i_s=floor(UE_ID / N)mod Ns

[0056] Some of the above parameters are explained as follows:

[0057] -T: DRX cycle in which the UE receives paging. The network device broadcasts a default DRX cycle. If the RRC / High layer configures a UE-specific DRX cycle for the UE, the minimum of the network device broadcasted DRX cycle and the RRC / High layer configured UE-specific DRX cycle is taken as the DRX cycle of the UE. If the RRC / High layer does not configure a UE-specific DRX cycle for the UE, the network device broadcasted DRX cycle is taken as the DRX cycle of the UE.

[0058] -N: number of PFs contained in one T.

[0059] -Ns: number of POs contained in one PF.

[0060] -PF_offset: a time domain offset used to determine PF.

[0061] -UE_ID: 5G-S-TMSI mod 1024.

[0062] After the UE calculates the PF, the index of PO, and the number of PDCCH monitoring occasions in the PO based on the above formula, the UE only needs to know the starting position of the first PDCCH monitoring occasion of the PO through the relevant configuration parameters, which is configured through high layer signaling. The UE blindly detects the paging message according to the determined PO.

[0063] When the UE detects a P-RNTI scrambled PDCCH on its own PO, and the PDCCH schedules a PDSCH (Physical Downlink Shared Channel), the UE decodes the PDSCH based on the PDCCH indication. The PDSCH is used to carry the Paging message, which contains a paging Record list, each paging Record of which indicates a UE ID. The UE determines whether it is paged according to the paging Record list.

[0064] 3. Random access procedure

[0065] The random access procedure is mainly triggered by the following events:

[0066] -UE initial access to establish a wireless connection: UE from RRC_IDLE state to RRC_CONNECTED state

[0067] - RRC connection reestablishment procedure: in order for the UE to reestablish the radio connection after a radio link failure

[0068] - handover: the UE needs to establish uplink synchronization with a new cell

[0069] - in RRC_CONNECTED state, DL (DownLink) data arrives, at this time, UL (UpLink) is in an out-of-sync state

[0070] - in RRC_CONNECTED state, UL data arrives, at this time, UL is in an out-of-sync state or there is no PUCCH (Physical Uplink Control Channel) resource for sending SR (Scheduling Request)

[0071] - SR failure

[0072] - synchronization reconfiguration request from RRC

[0073] - UE transitions from RRC_INACTIVE state to RRC_CONNECTED state

[0074] - time calibration is established in the SCell addition process

[0075] - request for other SI

[0076] - beam failure recovery

[0077] In the related art, the following two random access methods are mainly supported: a contention-based random access method and a non-contention-based random access method, as shown in FIG. 2.

[0078] The contention-based random access procedure shown in FIG. 2 is divided into 4 steps (as shown in FIG. 2(a)), and the non-contention-based random access procedure is divided into 2 steps (as shown in FIG. 2(b)). The detailed steps are as follows:

[0079] Step 1. The terminal device sends Msg1 to the network device

[0080] The terminal device selects a PRACH (Physical Random Access Channel) resource and sends a selected preamble on the selected PRACH. If it is a non-contention-based random access, the PRACH resource and the preamble can be specified by the base station. The base station can estimate the uplink timing based on the preamble and the grant size required by the terminal device to transmit Msg3.

[0081] step2. Network device sends RAR (Random Access Response) to terminal device

[0082] After terminal device sends Msg1, it starts a random access response time window ra-ResponseWindow, and monitors PDCCH scrambled by RA-RNTI (Random Access Radio Network Temporary Identifier) within the window. The calculation of RA-RNTI is as follows: RA-RNTI = 1 + s_id + 14 × t_id + 14 × 80 × f_id + 14 × 80 × 8 × ul_carrier_id

[0083] That is, RA-RNTI is related to the PRACH time-frequency resource used by UE to send Msg1.

[0084] After terminal device successfully receives PDCCH scrambled by RA-RNTI, the terminal device can obtain PDSCH scheduled by the PDCCH, which contains RAR (Random Access Response). The RAR specifically contains the following information:

[0085] BI (Backoff Indicator) in the subheader of RAR: used to indicate the backoff time of retransmitting Msg1;

[0086] RAPID (Random Access Preamble Identifier) in the subheader of RAR: the network device responds to the received preamble index;

[0087] TAG (Timing Advance Group) in the payload of RAR: used to adjust the uplink timing;

[0088] UL grant: used to schedule the uplink resource indication of Msg3;

[0089] Temporary C-RNTI (Cell Radio Network Temporary Identifier): used to scramble the PDCCH of Msg4 (initial access).

[0090] If the terminal device receives the PDCCH scrambled by RA-RNTI and the preamble index sent by itself is contained in the RAR, the terminal device considers that the random access response is successfully received.

[0091] For non-contention-based random access, the random access procedure ends after the terminal device successfully receives Msg2. For contention-based random access, after the terminal device successfully receives Msg2, the terminal device still needs to continue to transmit Msg3 and receive Msg4.

[0092] Step 3. The terminal device transmits Msg3 on the resource scheduled by the network device

[0093] Msg3 is mainly used to inform the network device that the RACH procedure is triggered by what event. For example, if it is an initial access random procedure, the UE ID and establishment cause will be carried in Msg3; if it is RRC reestablishment, the connected UE identifier and establishment cause will be carried.

[0094] Step 4. The network device sends Msg4 to the terminal device

[0095] Msg4 has two functions, one is for contention conflict resolution, and the second is that the network device transmits an RRC configuration message to the terminal device. There are two ways for contention conflict resolution: one is that if the UE carries C-RNTI in Msg3, Msg4 is scheduled by PDCCH scrambled by C-RNTI. The other is that if the UE does not carry C-RNTI in Msg3, such as initial access, Msg4 is scheduled by PDCCH scrambled by TC-RNTI, and the solution to the conflict is that the UE receives the PDSCH in Msg4 by matching the CCCH (Common Control Channel) SDU (Service Data Unit) in the PDSCH.

[0096] 4. Two-step random access procedure of NR

[0097] Two-step random access is introduced in the related art, which can reduce latency and reduce signaling overhead. As shown in FIG. 3, MsgA in the two-step random access includes preamble transmitted on PRACH and payload information transmitted on PUSCH. After transmitting MsgA, the terminal device listens to the response of the network side in the configured window. If MsgB indicating that the contention conflict resolution is successful is received from the network device, the terminal device ends the random access procedure.

[0098] 5. Energy saving of 6G terminal device

[0099] Terminal device energy saving is a key technology in the 6G stage. In order to further reduce the energy consumption of terminal devices while ensuring the performance of 6G, the concept of large and small cores is proposed.

[0100] This concept mainly refers to the fact that future 6G terminal devices can support "large and small core" design, that is, small core supports terminal devices working in an extremely energy-saving state, and when there is a large amount of traffic demand, the terminal device starts the large core to meet more stringent performance indicators.

[0101] In addition, the related art considers that Massive IoT terminal types need to be supported in the first version of 6G, combined with the concept of large and small cores, one understanding is that the small core is a Massive IoT terminal.

[0102] Based on the understanding in the related art, the Massive IoT terminal or small core has the characteristics of low power consumption and low complexity, and its supported working bandwidth is relatively small, such as 5MHz or narrower. Since the Massive IoT terminal or small core needs to support paging, RRC connection establishment and other processes. Since the Massive IoT terminal can only support narrowband transmission, the reduction of transmission bandwidth compared to NR will result in a decrease in maximum TBS.

[0103] For the paging process, the reduction of the paging message means that the number of UEs that the base station can page at the same time is reduced, thereby increasing the paging delay, and even causing paging congestion.

[0104] In the random access process, the base station can multiplex the same RA-RNTI RAR in a TB through concatenation transmission, so the reduction of PDSCH TBS means that the number of UEs that the base station can respond to at the same time is reduced, thereby increasing the Msg2 sending delay.

[0105] How to solve the above-mentioned impact of the narrowband transmission of the Massive IoT terminal or small core on paging and random access and ensure the performance of the 6G system is a problem that needs to be studied.

[0106] Please refer to FIG. 4, which shows a flowchart of a transmission scheduling method according to an embodiment of the present application. The method is performed by a first terminal device. The method includes the following step 410.

[0107] Step 410, the first terminal device receives first information, and the first information is used to schedule the transmission of a plurality of TBs.

[0108] Correspondingly, the network device sends the first information.

[0109] In some embodiments, the first information is DCI (Downlink Control Information). In some embodiments, the first information is DCI for scheduling data transmission. In some embodiments, the first information can also be DCI other than for scheduling data transmission. In some embodiments, the first information is DCI transmitted to multiple terminal devices. In some embodiments, the first information can also be DCI transmitted to the first terminal device. In some embodiments, the first information is carried in a downlink channel for transmitting control signaling. Exemplarily, the first information is carried in a PDCCH.

[0110] In some embodiments, the downlink channel corresponding to the multiple TBs is a downlink channel for transmitting data. Exemplarily, the downlink channel corresponding to the multiple TBs is a PDSCH. In some embodiments, the downlink channel corresponding to the multiple TBs is a downlink channel for transmitting signaling. Exemplarily, the downlink channel corresponding to the multiple TBs is a PDCCH.

[0111] In some embodiments, each scheduled TB corresponds to a terminal group, and each terminal group includes one or more terminal devices.

[0112] In some embodiments, the terminal devices divided into the terminal groups are determined based on messages carried by the multiple TBs. In some embodiments, the multiple TBs are used to carry paging messages. In some embodiments, terminal devices listening to paging messages on the same PO are divided into at least one terminal group. In some embodiments, the multiple TBs are used to carry Msg2 or MsgB. In some embodiments, terminal devices occupying the same time-frequency resources for transmitting Msg1 or MsgA are divided into at least one terminal group.

[0113] In some embodiments, the terminal groups are divided according to a maximum number of TBs supported by the first information for scheduling.

[0114] In some embodiments, the terminal groups are divided according to a number of TBs actually scheduled by the first information.

[0115] In some embodiments, the number of terminal devices included in each terminal group can be the same or different. Exemplarily, the terminal groups are divided according to an average of a maximum number of TBs supported by the first information for scheduling. Exemplarily, the terminal groups in which the terminal devices are located are divided according to paging probabilities of the terminal devices.

[0116] In some embodiments, the first information is used to indicate at least one of the following information:

[0117] a number of the multiple TBs;

[0118] time domain resources occupied by the downlink channel transmission corresponding to the plurality of TBs;

[0119] frequency domain resources occupied by the downlink channel transmission corresponding to the plurality of TBs;

[0120] terminal groups corresponding to each of the plurality of TBs.

[0121] In some embodiments, the first information is used to indicate identification information of the terminal groups corresponding to each of the plurality of TBs. In some embodiments, the identification information of the terminal groups is used to uniquely identify the terminal groups. Illustratively, the first information is used to indicate an index of the terminal groups corresponding to each of the plurality of TBs.

[0122] In some embodiments, the first information is used to implicitly or explicitly indicate the number of the plurality of TBs. Illustratively, the first information includes a first indication field, and the first indication field is used to indicate the number of the plurality of TBs. Illustratively, the number of time domain resources occupied by the downlink channel transmission corresponding to the plurality of TBs indicated by the first information has a corresponding relationship with the number of the plurality of TBs. For example, the number of time domain resources occupied by the downlink channel transmission corresponding to the plurality of TBs indicated by the first information is the same as the number of the plurality of TBs.

[0123] In some embodiments, the number of the plurality of TBs scheduled by the first information is less than or equal to the number of the at least one terminal group. Illustratively, the at least one terminal group is divided based on the maximum number of TBs supported by the first information, and the number of the plurality of TBs scheduled by the first information is less than or equal to the number of the at least one terminal group. Illustratively, the at least one terminal group is divided based on the number of TBs actually scheduled by the first information, and the number of the plurality of TBs scheduled by the first information is equal to the number of the at least one terminal group.

[0124] In some embodiments, the downlink channel transmission corresponding to the plurality of TBs occupies the same frequency domain resources and different time domain resources. In some embodiments, the downlink channel transmission corresponding to the plurality of TBs occupies the same frequency domain resources, and the first information can only indicate one frequency domain resource, without the need to indicate the frequency domain resources corresponding to each TB respectively, thereby reducing the overhead of the first information.

[0125] In some embodiments, the downlink channel transmission corresponding to the plurality of TBs occupies different frequency domain resources and the same or different time domain resources. In some embodiments, the downlink channel transmission corresponding to the plurality of TBs occupies different frequency domain resources and the same time domain resources, and the first information can only indicate one time domain resource, without the need to indicate the frequency domain resources corresponding to each TB respectively, thereby reducing the overhead of the first information. In some embodiments, the downlink channel transmission corresponding to the plurality of TBs occupies different frequency domain resources and different time domain resources, and the terminal device can receive and decode the plurality of TBs.

[0126] In some embodiments, after receiving the first information, the terminal device receives the plurality of TBs.

[0127] In some embodiments, the first terminal device cannot determine the terminal group it belongs to corresponds to the TB, and thus the first terminal device needs to decode the plurality of TBs one by one. In some embodiments, the first terminal device cannot determine the terminal group it belongs to, and thus the first terminal device also needs to decode the plurality of TBs one by one.

[0128] In some embodiments, the first terminal device decodes the plurality of TBs one by one, and stops decoding the remaining TBs after a second TB of the plurality of TBs is determined to be sent to the first terminal device.

[0129] In some embodiments, the first terminal device can determine the terminal group it belongs to corresponds to the TB, and thus the first terminal device can only decode the first TB, which is the TB corresponding to the terminal group the first terminal device belongs to.

[0130] In some embodiments, the first terminal device decodes the first TB, which is the TB corresponding to the terminal group the first terminal device belongs to, in a case that the plurality of TBs includes the first TB.

[0131] The technical scheme provided by the embodiments of the present application can schedule a plurality of TBs by the first information, without sending a first information for each TB, so as to reduce the power consumption of the network device sending the first information, and reduce the first information the terminal device needs to listen to, thereby saving the energy consumption of the terminal device.

[0132] The embodiments of the present application also provide exemplary embodiments to illustrate the content indicated by the first information.

[0133] In some embodiments, the first information is used to indicate at least one of the following information:

[0134] The number of the plurality of TBs;

[0135] The time domain resource occupied by the downlink channel transmission corresponding to the plurality of TBs;

[0136] The frequency domain resource occupied by the downlink channel transmission corresponding to the plurality of TBs;

[0137] The terminal group corresponding to each TB of the plurality of TBs.

[0138] In some embodiments, the first information explicitly or implicitly indicates the number of the plurality of TBs scheduled by the first information. For example, the first information explicitly indicates the number of the plurality of TBs scheduled by the first information. For example, the first information indicates that N TBs are scheduled, where N is an integer greater than 1. For example, the first information implicitly indicates the number of the plurality of TBs scheduled by the first information. For example, the terminal device determines N based on a mapping relationship between a modulation mode adopted by the first information and N, where N is the number of the plurality of TBs scheduled by the first information, and N is an integer greater than 1. For example, the first information indicates a first time domain pattern, the first time domain pattern is used to indicate time domain resources occupied by the plurality of TBs corresponding downlink channel transmissions, and the terminal device determines the number of the plurality of TBs based on a number of time domain resources indicated in the first time domain pattern. For example, the number of time domain resources indicated in the first time domain pattern is N, and the terminal device determines that N TBs are scheduled by the first information, where N is an integer greater than 1.

[0139] In some embodiments, the first information is used to indicate time domain resources occupied by the plurality of TBs corresponding downlink channel transmissions and / or frequency domain resources occupied by the plurality of TBs corresponding downlink channel transmissions.

[0140] I. The plurality of TBs corresponding downlink channel transmissions occupy the same frequency domain resources

[0141] In some embodiments, the first information is used to indicate a first frequency domain resource. The plurality of TBs corresponding downlink channel transmissions all occupy the first frequency domain resource. For example, the first information is used to indicate a frequency band 1, and the plurality of TBs corresponding downlink channel transmissions all occupy the frequency band 1.

[0142] 1. The plurality of TBs corresponding downlink channel transmissions occupy different time domain resources

[0143] In some embodiments, the time domain resources occupied by the plurality of TBs corresponding downlink channel transmissions are continuous. For example, the first information is used to schedule TB1-TB3, and the TB1-TB3 corresponding downlink channel transmissions occupy continuous time domain resources 1-3.

[0144] In some embodiments, the time domain resources occupied by the downlink channel transmissions corresponding to two adjacent TBs in the plurality of TBs are separated by a fourth time unit. The size of the fourth time unit is not limited in the present application. For example, the fourth time unit is 1 slot. For example, the first information is used to schedule TB1-TB3, the time domain resource 1 occupied by the downlink channel transmission corresponding to TB1 is separated from the time domain resource 2 occupied by the downlink channel transmission corresponding to TB2 by the fourth time unit, and the time domain resource 2 occupied by the downlink channel transmission corresponding to TB2 is separated from the time domain resource 3 occupied by the downlink channel transmission corresponding to TB3 by the fourth time unit.

[0145] In some embodiments, the time domain resources occupied by the downlink channel transmissions corresponding to the plurality of TBs are interleaved. In some embodiments, taking TB1 and TB2 as an example, TB1 initial transmission, TB2 initial transmission, TB1 retransmission and TB2 retransmission are interleaved transmissions. In some embodiments, the time domain resources occupied by the TB1 initial transmission, TB2 initial transmission, TB1 retransmission and TB2 retransmission can be continuous or discontinuous. Exemplarily, the time domain resources occupied by the TB1 initial transmission, TB2 initial transmission, TB1 retransmission and TB2 retransmission are separated by a fourth time unit.

[0146] In some embodiments, the intervals between the time domain resources occupied by the downlink channel transmissions corresponding to the plurality of TBs are different, and the first information respectively indicates the intervals between the time domain resources occupied by the downlink channels corresponding to two consecutive TBs in the plurality of TBs.

[0147] In some embodiments, the time domain resources occupied by the downlink channel transmissions corresponding to the plurality of TBs are determined based on a first time domain pattern. In some embodiments, the first information is used to indicate the first time domain pattern. Exemplarily, the first information indicates the first time domain pattern in the form of a bit map.

[0148] In some embodiments, the first terminal device receives a broadcast message, and the broadcast message is used to indicate one or more time domain patterns, and the one or more time domain patterns include the first time domain pattern. In some embodiments, the first information is used to indicate the identity of the first time domain pattern, and the first terminal device determines the first time domain pattern in the one or more time domain patterns based on the identity of the first time domain pattern.

[0149] In some embodiments, in the time domain pattern, the intervals between the time domain resources occupied by the downlink channel transmissions corresponding to two adjacent TBs can be the same or different.

[0150] In some embodiments, in the case where the downlink channel transmissions corresponding to the plurality of TBs occupy the same frequency domain resources and different time domain resources, the first information can indicate or can not indicate the terminal group corresponding to each TB in the plurality of TBs.

[0151] (1) The first information does not indicate the terminal group corresponding to each TB in the plurality of TBs

[0152] In some embodiments, the first terminal device sequentially decodes the plurality of TBs; in the case where it is determined that a second TB in the plurality of TBs is a TB sent to the first terminal device, the decoding of the remaining undecoded TBs after the second TB is stopped.

[0153] Exemplarily, the first terminal device sequentially decodes TB1-TB5, and in the case where it is determined that TB3 is a TB sent to the first terminal device, the decoding of TB4 and TB5 after TB3 is stopped.

[0154] In some embodiments, the terminal groups are divided according to the maximum number of TBs supported by the first information. In this case, if the first information does not indicate the terminal group corresponding to each of the plurality of TBs, the first terminal device cannot determine the TB corresponding to the first terminal device among the plurality of TBs. In this case, the first terminal device can sequentially decode the plurality of TBs based on the above method, and stop decoding the remaining undecoded TBs after the second TB among the plurality of TBs is determined to be the TB transmitted to the first terminal device.

[0155] In some embodiments, the terminal groups are divided according to the number of TBs actually scheduled by the first information. In this case, even if the first information does not indicate the terminal group corresponding to each of the plurality of TBs, the first terminal device can determine that the terminal group corresponding to the first TB is the terminal group in which the first terminal device is located.

[0156] In some embodiments, the first terminal device decodes the first TB, wherein the first TB is the TB corresponding to the terminal group in which the first terminal device is located. In this case, the first terminal device can directly decode the first TB without decoding other TBs other than the first TB.

[0157] (2) The first information indicates the terminal group corresponding to each of the plurality of TBs

[0158] In some embodiments, the terminal groups are divided according to the maximum number of TBs supported by the first information. In this case, if the first information indicates the terminal group corresponding to each of the plurality of TBs, the first terminal device can determine whether the first TB is included in the plurality of TBs.

[0159] In some embodiments, in the case where the first TB is included in the plurality of TBs, the first TB is decoded, wherein the first TB is the TB corresponding to the terminal group in which the first terminal device is located. In some embodiments, in the case where the first TB is included in the plurality of TBs, the TBs other than the first TB among the plurality of TBs are not decoded by the first terminal device. In some embodiments, in the case where the first TB is not included in the plurality of TBs, none of the plurality of TBs is decoded by the first terminal device. That is, the first terminal device only needs to decode the first TB.

[0160] In some embodiments, the terminal groups are divided according to the number of TBs actually scheduled by the first information. In this case, regardless of whether the first information indicates the terminal group corresponding to each of the plurality of TBs, the first terminal device can determine that the terminal group corresponding to the first TB is the terminal group in which the first terminal device is located.

[0161] In some embodiments, the first terminal device decodes the first TB, wherein the first TB is a TB corresponding to a terminal group to which the first terminal device belongs. In this case, the first terminal device can directly decode the first TB without decoding other TBs.

[0162] 2. The downlink channel transmissions corresponding to the plurality of TBs occupy the same time domain resource

[0163] In some embodiments, in the case where the downlink channel transmissions corresponding to the plurality of TBs occupy the same time domain resource, the first information is further used to indicate a first time unit, and the first time unit is used to determine a time interval between the first information and the downlink channel transmissions corresponding to the plurality of TBs. For example, in the case where the downlink channel transmissions corresponding to the plurality of TBs occupy the same time domain resource, the first information is used to indicate a time unit k, and the downlink channel transmissions corresponding to the plurality of TBs all occupy the time unit k.

[0164] In some embodiments, in the case where the downlink channel transmissions corresponding to the plurality of TBs occupy the same time domain resource and the same frequency domain resource, the first terminal device can only decode one of the plurality of TBs, and thus the above method in which the first terminal device sequentially decodes the plurality of TBs is not applicable. In this case, the first information is used to indicate a terminal group corresponding to each of the plurality of TBs.

[0165] In some embodiments, the terminal groups are divided according to a maximum number of TBs supported by the first information.

[0166] In some embodiments, in the case where the first TB is included in the plurality of TBs, the first TB is decoded, wherein the first TB is a TB corresponding to a terminal group to which the first terminal device belongs. In some embodiments, in the case where the first TB is included in the plurality of TBs, other TBs in the plurality of TBs except the first TB are not decoded by the first terminal device. In some embodiments, in the case where the first TB is not included in the plurality of TBs, none of the plurality of TBs is decoded by the first terminal device. That is, the first terminal device only needs to decode the first TB.

[0167] In some embodiments, the terminal groups are divided according to a number of TBs actually scheduled by the first information.

[0168] In some embodiments, the first terminal device decodes the first TB, wherein the first TB is a TB corresponding to a terminal group to which the first terminal device belongs. In this case, the first terminal device can directly decode the first TB without decoding other TBs.

[0169] II. The downlink channel transmissions corresponding to the plurality of TBs occupy different frequency domain resources

[0170] In some embodiments, the frequency domain resources occupied by the downlink channel transmissions corresponding to the plurality of TBs are located on different subbands. In some embodiments, the subband can also be referred to as a frequency domain narrowband.

[0171] In some embodiments, the subband includes any one of the following: a carrier, a narrow bandwidth, a BWP. In some embodiments, in the case where the subband includes a BWP, the BWP can be an initial BWP.

[0172] 1. The downlink channel transmissions corresponding to the plurality of TBs occupy different time domain resources

[0173] In some embodiments, the first information is further used to indicate a plurality of second time units, each second time unit being used to determine a time interval between the first information and the downlink channel transmission corresponding to one of the plurality of TBs.

[0174] In some embodiments, the first information is used to indicate a time interval between each of the plurality of TBs and the first information. For example, the first information is used to indicate time intervals 1-5, which respectively correspond to time intervals between TBs 1-5 and the first information. In some embodiments, the time interval between a TB and the first information refers to a time interval between a reception time of the TB and a reception time of the first information.

[0175] In some embodiments, the first information is further used to indicate a third time unit, the third time unit being used to determine a time interval between the first information and the downlink channel transmission on the main subband. For example, the first information is used to indicate time unit 1, and the first terminal device determines the time domain resources occupied by the downlink channel transmission corresponding to the TB on the main subband based on the time unit 1.

[0176] In some embodiments, a subband other than the main subband is referred to as a non-main subband.

[0177] In some embodiments, a time interval between the first information and the downlink channel transmission on the non-main subband is determined based on the third time unit and an offset value corresponding to the non-main subband. In some embodiments, the offset value corresponding to the non-main subband is configured by the network device. For example, the offset value corresponding to the non-main subband is configured by a system message. For example, the first information is used to indicate time unit 1, and the first terminal device determines the time domain resources occupied by the downlink channel transmission corresponding to the TB on the main subband based on the time unit 1, and determines the time domain resources occupied by the downlink channel transmission corresponding to the TB on the non-main subband 1 based on the time unit 1 and the offset value 1.

[0178] In some embodiments, in the case where the downlink channel transmissions corresponding to the plurality of TBs occupy different frequency domain resources and different time domain resources, the first information can indicate or can not indicate a terminal group corresponding to each of the plurality of TBs.

[0179] (1) The first information does not indicate the terminal group to which each of the plurality of TBs corresponds

[0180] In some embodiments, the first terminal device decodes the plurality of TBs in sequence; and in a case where it is determined that a second TB of the plurality of TBs is a TB sent to the first terminal device, the first terminal device stops decoding the remaining undecoded TBs after the second TB.

[0181] For example, the first terminal device decodes TB1-TB5 in sequence, and in a case where it is determined that TB3 is a TB sent to the first terminal device, the first terminal device stops decoding TB4 and TB5 after TB3.

[0182] In some embodiments, the terminal groups are divided according to a maximum number of TBs supported by the first information for scheduling. In this case, if the first information does not indicate the terminal group to which each of the plurality of TBs corresponds, the first terminal device cannot determine the TB corresponding to the first terminal device among the plurality of TBs. In this case, the first terminal device can decode the plurality of TBs in sequence based on the above method, and in a case where it is determined that a second TB of the plurality of TBs is a TB sent to the first terminal device, the first terminal device stops decoding the remaining undecoded TBs after the second TB.

[0183] In some embodiments, the terminal groups are divided according to a number of TBs actually scheduled by the first information. In this case, even if the first information does not indicate the terminal group to which each of the plurality of TBs corresponds, the first terminal device can determine that the terminal group corresponding to the first TB is the terminal group in which the first terminal device is located.

[0184] In some embodiments, the first terminal device decodes the first TB, wherein the first TB is a TB corresponding to the terminal group in which the first terminal device is located. In this case, the first terminal device can directly decode the first TB without decoding other TBs other than the first TB.

[0185] (2) The first information indicates the terminal group to which each of the plurality of TBs corresponds

[0186] In some embodiments, the terminal groups are divided according to a maximum number of TBs supported by the first information for scheduling. In this case, if the first information indicates the terminal group to which each of the plurality of TBs corresponds, the first terminal device can determine whether the first TB is included in the plurality of TBs.

[0187] In some embodiments, the first TB is included in the plurality of TBs, and the first TB is a TB corresponding to a terminal group to which the first terminal device belongs. In some embodiments, the first TB is included in the plurality of TBs, and the first terminal device does not decode a TB other than the first TB in the plurality of TBs. In some embodiments, the first TB is not included in the plurality of TBs, and the first terminal device does not decode any TB in the plurality of TBs. That is, the first terminal device only needs to decode the first TB.

[0188] In some embodiments, the terminal groups are divided according to a number of TBs actually scheduled according to the first information. In this case, the first terminal device can determine that the terminal group corresponding to the first TB is the terminal group to which the first terminal device belongs, regardless of whether the first information indicates the terminal group corresponding to each TB in the plurality of TBs.

[0189] In some embodiments, the first terminal device decodes the first TB, and the first TB is a TB corresponding to a terminal group to which the first terminal device belongs. In this case, the first terminal device can directly decode the first TB without decoding a TB other than the first TB.

[0190] 2. The downlink channel transmissions corresponding to the plurality of TBs occupy the same time domain resource

[0191] In some embodiments, when the downlink channel transmissions corresponding to the plurality of TBs occupy the same time domain resource, the first information is further used to indicate a first time unit, and the first time unit is used to determine a time interval between the first information and the downlink channel transmissions corresponding to the plurality of TBs. For example, when the downlink channel transmissions corresponding to the plurality of TBs occupy the same time domain resource, the first information is used to indicate a time unit k, and the downlink channel transmissions corresponding to the plurality of TBs occupy the same time unit k.

[0192] In some embodiments, when the downlink channel transmissions corresponding to the plurality of TBs occupy the same time domain resource and the same frequency domain resource, the first terminal device can only decode one TB in the plurality of TBs, and thus the above method in which the first terminal device sequentially decodes the plurality of TBs is not applicable. In this case, the first information is used to indicate a terminal group corresponding to each TB in the plurality of TBs.

[0193] In some embodiments, the terminal groups are divided according to a maximum number of TBs supported by the first information.

[0194] In some embodiments, the first TB is decoded by the first terminal device in a case that the first TB is included in the plurality of TBs, wherein the first TB is a TB corresponding to a terminal group in which the first terminal device is located. In some embodiments, other TBs than the first TB are not decoded by the first terminal device in a case that the first TB is included in the plurality of TBs. In some embodiments, none of the plurality of TBs is decoded by the first terminal device in a case that the first TB is not included in the plurality of TBs. That is, the first terminal device only needs to decode the first TB.

[0195] In some embodiments, the terminal groups are divided according to a number of TBs actually scheduled by the first information.

[0196] In some embodiments, the first TB is decoded by the first terminal device, wherein the first TB is a TB corresponding to a terminal group in which the first terminal device is located. In this case, the first terminal device can directly decode the first TB without decoding other TBs than the first TB.

[0197] In the above method, the scheme that the first terminal device sequentially decodes the plurality of TBs provides higher flexibility for scheduling the plurality of TBs by the first information, and the network device can determine the number of TBs to be scheduled based on the actual demand for RARs to be paged or actually sent. The scheme that the first terminal device directly decodes the first TB reduces the power consumption of the terminal device without sequentially decoding the plurality of TBs, which is more conducive to energy saving of the terminal device.

[0198] The terminal group corresponding to the TB is mentioned several times in the above embodiments. The present application also provides exemplary embodiments for how to determine the terminal group corresponding to the TB.

[0199] In some embodiments, the terminal groups are divided according to a maximum number of TBs supported by the first information to be scheduled. In some embodiments, the number of TBs actually scheduled by the first information is less than or equal to the maximum number of TBs supported by the first information to be scheduled. In some embodiments, the terminal groups are divided according to the maximum number of TBs supported by the first information to be scheduled, and the terminal group corresponding to each TB is relatively fixed.

[0200] In some embodiments, the terminal groups are divided according to a number of TBs actually scheduled by the first information. In some embodiments, the number of TBs scheduled by the first information each time can be different, and the terminal groups are relatively dynamic.

[0201] In some embodiments, the division manner of the terminal groups is different in different scenarios. Next, taking a case that the plurality of TBs are used to carry paging messages or RARs in a random access process as an example, an exemplary description is made.

[0202] I. The plurality of TBs are used to carry paging messages

[0203] In some embodiments, the terminal devices listening to the paging message on the same PO are divided into at least one terminal group.

[0204] In some embodiments, the terminal groups are divided based on the identification information respectively corresponding to the terminal devices. In some embodiments, the terminal devices are evenly divided into the terminal groups based on the identification information respectively corresponding to the terminal devices. Illustratively, the terminal devices are evenly divided into N1 terminal groups based on the identification information respectively corresponding to the terminal devices, N1 being the maximum number of TBs supported by the first information for scheduling. Illustratively, the terminal devices are evenly divided into N2 terminal groups based on the identification information respectively corresponding to the terminal devices, N2 being the number of TBs actually scheduled by the first information.

[0205] In some embodiments, the terminal groups are divided based on the paging probability respectively corresponding to the terminal devices. Illustratively, the paging probability is evenly divided into N1 groups from 0 to 1 (0% to 100%), and the terminal devices are divided into the corresponding terminal groups according to the corresponding paging probability, N1 being the maximum number of TBs supported by the first information for scheduling.

[0206] In some embodiments, the paging probability corresponding to the terminal devices is configured by the network device.

[0207] In some embodiments, the paging probability corresponding to the terminal devices is determined by the terminal device and the network device. Illustratively, the terminal device sends a first paging probability to the network device, and the network device determines the paging probability corresponding to the terminal device based on the first paging probability. In some embodiments, the network device can determine the first paging probability as the paging probability corresponding to the terminal device, or can not consider the first paging probability. In some embodiments, the first paging probability is determined by the terminal device based on its own characteristics.

[0208] In some embodiments, the paging probability respectively corresponding to each terminal group is indicated by the network device. Illustratively, the paging probability respectively corresponding to each terminal group is indicated by the system message. Illustratively, the system message indicates the threshold value of the paging probability respectively corresponding to each terminal group. Illustratively, the system message indicates that the threshold value of the paging probability respectively corresponding to TB1-TB5 is 0-20%, 21%-40%, 41%-60%, 61%-80%, and 81%-100%.

[0209] In some embodiments, the above method can result in a large difference in the number of terminal devices included in each terminal group, and therefore the terminal groups can be divided in combination with the identification information and the paging probability of the terminal devices.

[0210] In some embodiments, the terminal grouping is divided based on the identification information and the paging probability of the terminal devices respectively. In some embodiments, the terminal grouping is first divided into at least one terminal grouping set based on the paging probability of the terminal devices, and then each terminal grouping set is divided into at least one terminal grouping based on the identification information of the terminal devices. In some embodiments, the terminal grouping is first divided into at least one terminal grouping set based on the identification information of the terminal devices, and then each terminal grouping set is divided into at least one terminal grouping based on the paging probability of the terminal devices.

[0211] In some embodiments, the terminal grouping is indicated by the network device. In some embodiments, the terminal grouping is indicated by the system message.

[0212] By the above method, the terminal devices listening to the paging message on the same PO are divided into multiple terminal groupings, the first information scheduling multiple TBs is realized, the first information required to be sent in the paging process is reduced, and the paging delay is reduced.

[0213] II. Multiple TBs are used to carry Msg2 or MsgB

[0214] In some embodiments, terminal devices sending Msg1 or MsgA occupying the same time-frequency resources are divided into at least one terminal grouping. In some embodiments, since the terminal devices sending Msg1 or MsgA occupy the same time-frequency resources, the same identification information (such as RA-RNTI) is used to listen to the first information, and before the conflict is resolved, the network device cannot know the terminal identification information (such as the UE ID corresponding to the terminal device) corresponding to the terminal device, so it is not convenient to divide the terminal grouping by using the identification information of the terminal device. However, the preamble carried in Msg1 or MsgA sent by each terminal device is different, which can be used to distinguish each terminal device.

[0215] In some embodiments, Msg1 is used to carry a random access preamble, and MsgA is used to carry a random access preamble and PUSCH. In some embodiments, Msg2 is used to carry RAR, and MsgB is used to carry RAR and PDSCH.

[0216] In some embodiments, the terminal groups are divided based on the preambles transmitted by the terminal devices in Msg1 or MsgA. In some embodiments, the terminal devices are divided into terminal groups based on the indexes of the preambles transmitted by the terminal devices in Msg1 or MsgA. Illustratively, the terminal devices are evenly divided into N1 terminal groups based on the indexes of the preambles transmitted by the terminal devices in Msg1 or MsgA, where N1 is the maximum number of TBs supported by the first information. Illustratively, the terminal devices are evenly divided into N2 terminal groups based on the indexes of the preambles transmitted by the terminal devices in Msg1 or MsgA, where N2 is the number of TBs actually scheduled by the first information.

[0217] In some embodiments, the terminal groups are divided based on the preambles supported by the network device. In some embodiments, the network device supports M1 preambles, the M1 preambles are divided into multiple groups, and the terminal devices determine their terminal groups according to the terminal groups in which the preambles corresponding to the terminal devices belong. In some embodiments, there are M2 terminal devices that occupy the same time-frequency resources for transmitting Msg1 or MsgA, where M2 is less than or equal to M1. M1 and M2 are positive integers. Illustratively, the network device supports 16 preambles, the 16 preambles are evenly divided into 4 groups, and the terminal devices determine their terminal groups according to the preambles corresponding to the terminal devices. Illustratively, M2 = 10, and the 10 terminal devices determine in which of the above 4 groups they belong according to the preambles corresponding to the terminal devices.

[0218] In some embodiments, the terminal groups are indicated by the network device. In some embodiments, the terminal groups are indicated by system messages.

[0219] By the above method, the terminal devices that occupy the same time-frequency resources for transmitting Msg1 or MsgA are divided into multiple terminal groups, multiple TBs are scheduled by the first information, the first information required to be transmitted in the random access process is reduced, and the latency of the random access response is reduced.

[0220] In the above method embodiment, the technical solutions of the present application are introduced and described only from the perspective of the interaction between the terminal device and the network device. The steps performed by the terminal device described above can be implemented alone as a transmission scheduling method on the terminal device side, and the steps performed by the network device described above can be implemented alone as a transmission scheduling method on the network device side. In addition, the embodiments provided in the present application can be combined in any manner to form new embodiments, which are all within the protection scope of the present application.

[0221] The following is a device embodiment of the present application, which can be used to execute the method embodiments of the present application. For details not disclosed in the device embodiments of the present application, please refer to the method embodiments of the present application.

[0222] Please refer to Fig. 5, which shows a block diagram of a transmission scheduling apparatus provided by an embodiment of the present application.

[0223] The receiving module 510 is configured to receive first information, where the first information is used for scheduling transmission of a plurality of transport blocks (TBs).

[0224] In some embodiments, each of the scheduled TBs corresponds to a terminal group, and each terminal group includes one or more terminal devices.

[0225] In some embodiments, the apparatus 500 further includes a processing module (not shown in the figure).

[0226] The processing module is configured to, in a case where the plurality of TBs include a first TB, decode the first TB, where the first TB is a TB corresponding to a terminal group in which the first terminal device is located.

[0227] In some embodiments, in a case where the plurality of TBs do not include the first TB, none of the plurality of TBs is decoded by the first terminal device; or, in a case where the plurality of TBs include the first TB, none of the plurality of TBs except the first TB is decoded by the first terminal device.

[0228] In some embodiments, the processing module is further configured to decode the first TB, where the first TB is a TB corresponding to a terminal group in which the first terminal device is located.

[0229] In some embodiments, the TBs are used to carry paging messages, and terminal devices listening to the paging messages on a same paging occasion (PO) are divided into at least one terminal group.

[0230] In some embodiments, the terminal groups are divided based on identification information respectively corresponding to the terminal devices; or, the terminal groups are divided based on paging probabilities respectively corresponding to the terminal devices; or, the terminal groups are divided based on both the identification information and the paging probabilities respectively corresponding to the terminal devices; or, the terminal groups are indicated by a network device.

[0231] In some embodiments, the paging probabilities respectively corresponding to the terminal devices are configured by a network device; or, the paging probabilities respectively corresponding to the terminal devices are determined by the terminal devices and the network device in negotiation.

[0232] In some embodiments, the TBs are used to carry Msg2 or MsgB, and terminal devices occupying same time-frequency resources for transmitting Msg1 or MsgA are divided into at least one terminal group.
