Description

Technical Field

[0001] This disclosure relates to, but is not limited to, the field of wireless communication technology, and particularly to a downlink transmission configuration, receiving method and apparatus, communication device and storage medium. Background Technology

[0002] In the Long Term Evolution (LTE) fourth-generation (4G) mobile communication system, two major technologies were proposed to support Internet of Things (IoT) services: Machine Type Communication (MTC) and Narrow Band Internet of Things (NB-IoT). These two technologies primarily target scenarios with low data rates and high latency, such as meter reading and environmental monitoring. Currently, NB-IoT can only support a maximum data rate of a few hundred kilobytes per second (Mbps), while MTC can only support a few megabytes per second (Mbps). However, with the continuous development of IoT services, such as video surveillance, smart homes, wearable devices, and industrial sensing and monitoring, these services typically require data rates of tens to 100 megabytes per second (Mbps) and relatively high latency. Therefore, the MTC and NB-IoT technologies in LTE are difficult to meet these requirements.

[0003] In light of this situation, related technologies have proposed the design of a new user equipment (UE) within the new air interface of 5G systems to cover these mid-range IoT devices. This new terminal type is called Reduced Capability User Equipment (Redcap, UE) or simply New Radio Lightweight Terminal (NR-lite). Summary of the Invention

[0004] This disclosure provides a downlink transmission configuration, a receiving method and apparatus, a communication device, and a storage medium.

[0005] A first aspect of this disclosure provides a downlink transmission configuration method, wherein the method is executed by an accessed device, the method comprising:

[0006] Configure the small data transmission SDT and paging messages of the UE of the predetermined type in the same initial downlink DL bandwidth portion BWP or in different time units of different initial DL BWPs.

[0007] A second aspect of this disclosure provides a downlink transmission and reception method, wherein the method is executed by a predetermined type of user equipment (UE), the method comprising:

[0008] Receive SDT and paging messages on the same initial DL BWP, or receive small data transmission SDT and paging messages on different time units of different initial DL BWPs.

[0009] A third aspect of this disclosure provides a downlink transmission receiving method, wherein the method is executed by a user equipment (UE) of a predetermined type, the method comprising: in response to a conflict between a time unit for receiving a SDT and a time unit for listening to a paging message, receiving the SDT or listening to the paging message according to priority.

[0010] A fourth aspect of this disclosure provides a downlink transmission configuration method, wherein the method is executed by an accessed device, the method comprising:

[0011] Send network-side configuration, wherein the network-side configuration indicates priority, the priority being used to resolve conflicts between the time unit for receiving SDT and the time unit for listening to paging messages for a predetermined type of UE.

[0012] A fifth aspect of this disclosure provides a downlink transmission configuration apparatus, wherein the apparatus includes:

[0013] The configuration module is configured to configure small data transmission SDT and paging messages of a predetermined type of UE on the same initial downlink bandwidth portion (BWP) or on different time units of different initial downlink bandwidth portions (BWPs).

[0014] A sixth aspect of this disclosure provides a downlink transmission and reception apparatus, wherein the apparatus includes:

[0015] The first receiving module is configured to receive SDT and paging messages on the same initial DL BWP, or to receive small data transmission SDT and paging messages on different time units of different initial DL BWPs.

[0016] A seventh aspect of this disclosure provides a downlink transmission and reception apparatus, wherein the apparatus includes:

[0017] The second receiving module is configured to receive SDT or listen to paging messages according to priority in response to a conflict between the time unit for receiving SDT and the time unit for listening to paging messages.

[0018] An eighth aspect of this disclosure provides a downlink transmission configuration apparatus, the apparatus comprising:

[0019] The transmitting module is configured to transmit network-side configuration, wherein the network-side configuration indicates a priority, which is used to resolve conflicts between the time units for receiving SDT and the time units for listening to paging messages for a predetermined type of UE.

[0020] A ninth aspect of this disclosure provides a communication device, including a processor, a transceiver, a memory, and an executable program stored in the memory and executable by the processor, wherein the processor executes the executable program and performs the method provided by any one of the first to fourth aspects described above.

[0021] A tenth aspect of this disclosure provides a computer storage medium storing an executable program; the executable program, when executed by a processor, can implement the method provided by any one of the first to fourth aspects described above.

[0022] The technical solution provided in this disclosure takes into account that the UE of the predetermined type does not support or does not expect to receive SDT and listening paging messages in the same time unit of different initial DL BWPs. It configures the downlink transmission of SDT and paging messages on the same initial DL BWP or different time units of different initial DL BWPs, thereby solving the problem that the UE of the predetermined type does not support or does not expect to receive SDT and listening paging messages in the same time unit of different initial DL BWPs, thereby ensuring the success rate of receiving paging messages and downlink transmission of SDT for the predetermined type of UE.

[0043] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several UEs 11 and several access devices 12.

[0044] UE11 can be a device that provides voice and / or data connectivity to a user. UE11 can communicate with one or more core networks via a Radio Access Network (RAN). UE11 can be an IoT UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE11 can be a device in an unmanned aerial vehicle (UAV). Alternatively, UE11 can be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, UE11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0045] Access device 12 can be a network-side device in a wireless communication system. This wireless communication system can be a 4G system (also known as Long Term Evolution, LTE); or it can be a 5G system (also known as a New Radio, NR, or 5G NR system). Alternatively, it can be the next generation after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0046] The access device 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, the access device 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access device 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access device 12.

[0047] Access device 12 and UE11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0048] In some embodiments, UE11 can also establish E2E (End to End) connections. Examples include V2V (vehicle to vehicle), V2I (vehicle to Infrastructure), and V2P (vehicle to pedestrian) communication scenarios in vehicle-to-everything (V2X) communication.

[0049] In some embodiments, the wireless communication system described above may further include a network management device 13.

[0050] Several access devices 12 are connected to network management device 13. Network management device 13 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 13 is not limited in this embodiment.

[0051] like Figure 2A As shown, this disclosure provides a downlink transmission configuration method, which is executed by the accessed device. The method includes:

[0052] S110: Configure the SDT and paging messages of the predefined type UE on the same initial DL BWP, or configure them on different time units of different initial DL BWPs.

[0053] The access device may include any device within the access network; for example, the access device may specifically be a base station.

[0054] For example, the predetermined type of UE can be any UE that does not support receiving data on two or more initial DL BWPs at once or does not wish to receive data on two or more initial DL BWPs at once.

[0055] This pre-defined type of UE includes, but is not limited to: Redcap UE.

[0056] Similar to IoT devices in LTE, Redcap UEs based on 5G New Radio (NR) - lite terminals typically need to meet the following requirements: low cost, low complexity, a certain degree of coverage enhancement, and power savings. This means the UE may support relatively small bandwidths, such as limited to 5 MHz or 10 MHz, or limit the size of the NR-lite buffer, thereby limiting the size of each received transmission block, etc. For power savings, possible optimization directions include simplifying the communication process and reducing the number of times NR-lite users need to detect the downlink control channel.

[0057] The SDT mentioned here includes at least the downlink transmission of the SDT. This downlink transmission may include feedback on the uplink transmission of the SDT, transmission scheduling, and / or PDSCH transmission. The feedback on the uplink transmission of the SDT includes, but is not limited to, uplink Hybrid Automatic Repeat reQuest (HARQ) feedback sent via PDCCH. This HARQ feedback may include: acknowledgment (ACK) feedback indicating successful transmission and / or denial feedback (NACK). This HARQ feedback can be based on a transmission block (TB) or a code block group (CBG).

[0058] The transmission scheduling includes, but is not limited to, at least one of the following: PDCCH scheduling, PUCCH scheduling, PDSCH scheduling, and PUSCH scheduling transmitted via PDCCH.

[0059] Configuration information for transmission configurations that place the SDT and paging messages of a predetermined type of UE in the same initial DLBWP or in different time units with different initial DLBWPs can be sent to the predetermined type of UE via various messages, such as system messages, RRC messages, or MAC CE messages. This is merely an example, and actual implementations are not limited to this.

[0060] For example, such as Figure 2B As shown, this disclosure provides a downlink transmission configuration method that may include:

[0061] S110A: Place the SDT and paging messages of the predefined type UE on the same initial DL BWP.

[0062] If SDT and paging messages are configured on the same initial DL BWP, then a predetermined type of UE can receive the SDT and paging messages in the same and / or different time units on an initial DL BWP.

[0063] like Figure 2C As shown, the downlink transmission configuration method provided in this disclosure embodiment may include:

[0064] S110B: Configure the SDT and paging messages of the predefined type UE on different time units on different initial DL BWPs.

[0065] If the SDT and paging messages of a UE of a predetermined type are configured in different time units on different initial DL BWPs, then the UE of the predetermined type can switch to the initial DL BWP for transmitting SDT or switch to the initial DL BWP for sending paging messages in the corresponding time unit.

[0066] In this embodiment of the disclosure, the time unit can be a time resource unit of any size in the time domain. For example, the time unit can be a time slot, a sub-time slot, or a symbol.

[0067] In some embodiments, S110B may include:

[0068] Based on the required switching time between different BWPs for the predetermined type of UE, the SDT and paging message are configured on different units of different initial DL BWPs; the time interval between the time unit of the SDT and the time unit of the paging message is greater than or equal to the required switching time between different BWPs for the predetermined type.

[0069] The time interval between the time unit for receiving SDT and the time unit for listening to paging messages of the predetermined type UE needs to be greater than or equal to the time required for the predetermined type UE to switch between different BWPs. In this way, it can be ensured that the predetermined type UE can successfully listen to paging messages and receive SDTs at different time units on different initial DL BWPs.

[0070] In some embodiments, the predetermined type UE is at least one of the following:

[0071] Capability reduction UE;

[0072] It is prohibited to configure the SDT and paging messages in the same time unit of UEs with different initial DL BWPs;

[0073] It is not desirable to configure the SDT and paging messages in the same time unit of different initial DL BWPs for UEs.

[0074] The capability reduction UE mentioned here is the aforementioned Redcap UE.

[0075] In some embodiments, communication standard protocols, proprietary protocols, or communication operators may predetermine that: some UEs' SDT downlink transmissions and paging messages are coordinated in the same time unit of different initial DL BWPs for UEs; or, the UEs themselves report that they do not expect SDT and paging messages to be configured in the same time unit of different initial DL BWPs for UEs.

[0076] like Figure 3A As shown, this disclosure provides a downlink transmission and reception method, which is executed by a predetermined type of user equipment (UE). The method includes:

[0077] S210: Receive SDT and paging messages on the same initial DL BWP, or receive small data transmission SDT and paging messages on different time units of different initial DL BWPs.

[0078] The UE type here can be:

[0079] Capability-reduced UE; the capability-reduced UE here refers to the aforementioned Redcap UE;

[0080] or,

[0081] It is prohibited to configure the SDT and paging messages in the same time unit of UEs with different initial DL BWPs;

[0082] or,

[0083] It is not desirable to configure the SDT and paging messages in the same time unit of different initial DL BWPs for UEs.

[0084] like Figure 3B As shown, this disclosure provides a downlink transmission and reception method that may include:

[0085] S210A: Receive SDT and paging messages on the same initial DL BWP.

[0086] Pre-defined type UEs receive SDT and paging messages on the same initial DL BWP, so that pre-defined type UEs can receive SDT and listen to paging messages on the same or different time units without switching initial DL BWPs.

[0087] like Figure 3C As shown, this disclosure provides a downlink transmission and reception method that may include:

[0088] S210B: Receives small data transmission SDT and paging messages at different time units of different initial DL BWPs.

[0089] The pre-defined type UE receives SDT and listens for paging messages on different initial DL BWPs. This can solve the problem of SDT reception failure and / or paging message listening failure caused by the pre-defined type UE not supporting or not wanting to receive SDT and listen for paging messages in the same time unit on different initial DL BWPs.

[0090] In some embodiments, the time interval between the time unit for receiving the SDT and the time unit for the paging message is greater than or equal to the required duration for switching between different BWPs of the predetermined type.

[0091] That is, the time interval between the time unit for receiving SDT and the time unit for listening to paging messages is greater than or equal to the time required for switching between different BWPs of the predetermined type.

[0092] A predefined type UE may include one or more communication modules.

[0093] For example, a UE of a predetermined type may have a communication module. This communication module may include an antenna and radio frequency circuitry connected to the antenna. The communication module can only transmit and receive signals corresponding to the BWP transmission after its operating parameters are adjusted. For example, these operating parameters include, but are not limited to, the length of the antenna elements. Of course, the above is merely an example.

[0094] For example, if a UE of a predetermined type has multiple communication modules, due to power consumption and / or load considerations, at any given time, only one communication module of the UE may be in a working state, while other communication modules may be in a non-working state such as a shutdown or sleep state. If the UE of the predetermined type achieves the initial DL BWP handover by switching the communication module in working mode, some handover time is also required.

[0095] Considering the time required for the initial DL BWP to handle the handover of a predefined type of UE, if the downlink transmission of the predefined type's SDT and paging messages are configured on different initial DL BWPs, firstly, the receiving time unit for the predefined type UE to receive the SDT and the listening time unit for the paging messages will be configured on different time domain resources. Secondly, the time interval between the receiving time unit for the SDT and the listening time unit for the paging messages must be at least equal to or even greater than the handover time required for the predefined type UE on different initial DL BWPs to ensure the success rate of SDT reception and the success rate of paging message listening for the predefined type UE.

[0096] like Figure 4 As shown, this disclosure provides a downlink transmission and reception method, which is executed by a user equipment (UE) of a predetermined type. The method includes:

[0097] S310: In response to a conflict between the time unit for receiving SDT and the time unit for listening to paging messages, receive SDT or listen to paging messages according to priority.

[0098] In some embodiments, if a UE of a predetermined type discovers a conflict between the time unit for receiving SDT and the time unit for listening to paging messages, it will determine whether to receive SDT or listen to paging messages based on priority. Thus, the network side does not need to consider this conflict when configuring the time units for receiving SDT and listening to paging messages for the predetermined type of UE.

[0099] The conflict between the time unit for receiving SDT and the time unit for listening to paging messages includes, but is not limited to:

[0100] The time unit for receiving SDT and the time unit for listening to paging messages are located in the same time unit on different initial DL BWPs;

[0101] And / or,

[0102] The time unit for receiving SDT and the time unit for listening to paging messages are located in the first and second time units on different initial DL BWPs, and the time interval between the first and second time units is less than the time required for a predetermined type of UE to switch on different initial DL BWPs.

[0103] Of course, the above are just examples of the time units for receiving SDT and listening to paging messages; the actual implementation is not limited to these.

[0104] In some embodiments, the priority may be a dedicated priority established to resolve conflicts between the time units for receiving SDTs and the time units for listening to paging messages for a predetermined type of UE.

[0105] In other embodiments, the priority may be to share other priorities to resolve the conflict between the time unit for receiving SDT and the time unit for listening to paging messages. This shared priority may include the priority of any transmission parameters or attributes of the predetermined type of UE receiving SDT and paging messages. For example, the shared priority may be based on the channel priority of the SDT transmission channel and the paging message transmission channel, etc. If other priorities are shared, the network side does not need to specifically set priorities and send them to the UE to resolve the conflict between the time unit for receiving SDT and the time unit for listening to paging messages for the predetermined type of UE, thereby reducing signaling overhead and network-side configuration operations.

[0106] In some embodiments, the priority includes:

[0107] Priority of network-side configurations;

[0108] And / or,

[0109] Predefined priority.

[0110] The priority configured on the network side can be: the aforementioned dedicated priority and / or shared priority.

[0111] The predefined priority can be: the aforementioned dedicated priority and / or shared priority.

[0112] For example, predefined priorities may include: priorities predefined in standard protocols, proprietary protocols, or pre-defined priorities in base stations or UEs.

[0113] In some embodiments, the priority includes at least one of the following:

[0114] BWP priority;

[0115] Priority of business type;

[0116] Channel priority;

[0117] Priority of arrival time; the time of arrival is positively correlated with the priority.

[0118] Priority of services and channels.

[0119] In some embodiments, when the time unit for receiving SDT and the time unit for listening to paging messages of a predetermined type UE are different in the initial DL BWP, the priority of receiving SDT or listening to paging messages can be determined directly based on the priority of the network side or the predefined initial DL BWP.

[0120] For example, if the priority of the initial DL BWP containing the time unit for receiving the SDT is higher than the priority of the initial DL BWP containing the time unit for listening to the paging message, then the UE of the predetermined type will prioritize receiving the SDT when the above-mentioned conflict occurs. If the priority of the initial DL BWP containing the time unit for receiving the SDT is lower than the priority of the initial DL BWP containing the time unit for listening to the paging message, then the UE of the predetermined type will prioritize listening to the paging message when the above-mentioned conflict occurs.

[0121] The priority of the service type indicates the priority of the service to which the SDT and paging message belong, or the service priority configured for the SDT and paging message.

[0122] In one embodiment, SDT involves data transmission, while the paging message is a paging message that paging the UE to enable the UE to switch from an RRC disconnected state to an RRC connected state. The non-RRC connected state includes, but is not limited to, RRC idle state and / or RRC inactive state. The paging message can be sent on one or more paging occupancy (PO) events, and the service priority of all SDTs can be set higher than the service priority of the paging message.

[0123] In another embodiment, service priority can also be determined based on the service content of the SDT. For example, the service content of the SDT may include Ultra Reliable and Low Latency Communication (URLLC), which may have a higher priority than Enhanced Mobile Broadband (eMBB). In this case, when a UE of a predetermined type discovers a conflict between the time unit for receiving the SDT and the time unit for listening to paging messages, if the service content of the SDT is URLLC, it will prioritize receiving the SDT and not listen to the conflicting paging messages; if the service content of the SDT is eMBB, it will prioritize listening to paging messages and not receive the conflicting SDT.

[0124] The channels for transmitting SDT and paging messages both include PDSCH and / or PDCCH. In some embodiments, different downlink channels are configured with different channel priorities. A predetermined type UE can directly multiplex the channels containing the SDT and paging messages to resolve conflicts between the time units for receiving SDT and paging messages. In some embodiments, the time units for SDT and paging messages overlap, but only partially, or the interval is less than the handover time required for the predetermined type UE on different initial DL BWPs. In this case, there is still a priority between the time units for SDT and paging messages. The arrival time here refers to the start time of the conflicting time units for receiving SDT and listening to paging messages. In this embodiment, the arrival time is positively correlated with priority; that is, the earlier the arrival time, the higher the priority; the later the arrival time, the lower the priority. In this case, when a predetermined type UE detects the above conflict, if the arrival time of the SDT receiving time unit is earlier than the time unit for listening to paging messages, it prioritizes receiving the SDT; if the arrival time of the SDT receiving time unit is later than the time unit for listening to paging messages, it prioritizes listening to paging messages. If a UE of a predetermined type discovers the above conflict, and the arrival time of the received SDT time unit and the paging message listening time unit are the same, it can determine whether to prioritize receiving the SDT or prioritizing paging messages according to other priorities; or, randomly select or according to a preset setting, prioritize receiving the SDT or prioritizing paging messages.

[0125] The priority of services and channels in this embodiment is a priority that takes into account both channel type and service type, so that when resolving the above-mentioned conflicts, the UE of the predetermined type can simultaneously take into account both channels and services, thereby improving the communication quality of the UE of the predetermined type.

[0126] For example, regarding the priority of the service type, the service type priority of the SDT is higher than the service type priority of the paging message. If the service priority of the SDT is set higher than the service priority of the paging message, the UE of the preset type will receive the SDT first and determine the transmission of service data first.

[0127] In some embodiments, regarding the channel priority, the Physical Downlink Shared Channel (PDSCH) has a higher channel priority than the Physical Downlink Control Channel (PDCCH); or, the PDSCH has a lower channel priority than the PDCCH.

[0128] The channels for transmitting SDT and paging messages can be either PDSCH and / or PDCCH.

[0129] In one embodiment, the channel priority of PDSCH can be set higher than that of PDCCH, or the channel priority of PDSCH can be set lower than that of PDCCH.

[0130] For example, the priorities for the services and channels have at least one of the following:

[0131] For PDCCH transmission of SDT, the priority of SDT is higher than the priority of the wake-up signal of the paging message;

[0132] For the PDCCH transmission of SDT, the priority of SDT is higher than the priority of the PDCCH transmission of the paging message;

[0133] For the PDCCH transmission of SDT, the priority of SDT is higher than the priority of the PDSCH transmission of the paging message;

[0134] For PDSCH transmission of SDT, the wake-up signal of the paging message has a higher priority than the SDT.

[0135] For PDSCH transmission of SDT, the PDCCH transmission of the paging message has a higher priority than the SDT priority;

[0136] For PDSCH transmission of SDT, the priority of SDT is higher than the priority of PDSCH transmission of paging messages.

[0137] In some embodiments, the preset type UE takes into account both channel priority and service priority, thereby determining, from two aspects, whether to prioritize receiving SDT or listening to paging messages when the time unit for receiving SDT conflicts with the time unit for listening to paging messages.

[0138] The wake-up signal of the paging message is generally transmitted at a point in time before the paging message is sent, and is used to indicate that a predetermined type needs to listen for the paging message corresponding to the wake-up signal.

[0139] like Figure 5 As shown, this disclosure provides a downlink transmission configuration method, which is executed by the accessed device. The method includes:

[0140] S410: Send network-side configuration, wherein the network-side configuration indicates a priority, the priority being used to resolve conflicts between the time unit for receiving SDT and the time unit for listening to paging messages for a predetermined type of UE.

[0141] The access equipment includes, but is not limited to, base stations.

[0142] Send network configuration, which can resolve the conflict between the time unit for receiving SDT and the time unit for listening to paging messages mentioned in any of the foregoing embodiments by explicitly indicating and / or implicitly indicating a predetermined type.

[0143] The network-side configuration can be broadcast, multicast, or unicast.

[0144] For example, this network configuration can be carried in a System Information Block (SIB). This SIB can be the main information block or any SIB other than the main information block. By broadcasting, even before a UE of a preset type has accessed the cell, it is possible to preferentially know how to resolve conflicts between the time units for receiving SDTs and the time units for paging messages.

[0145] In some embodiments, the network-side configuration includes:

[0146] SIB configuration.

[0147] RRC configuration;

[0148] MAC CE configuration;

[0149] DCI configuration.

[0150] The SIB configuration, i.e. the network-side configuration, is carried within the SIB.

[0151] RRC configuration, that is, the network-side configuration carried in any type of RRC message.

[0152] The MAC CE configuration, i.e. the network-side configuration, is carried in the MAC CE.

[0153] The DCI configuration, i.e. the network-side configuration, is carried in the DCI.

[0154] This disclosure provides a method for receiving SDT and listening paging messages to solve the problem that a predetermined type of UE cannot simultaneously receive SDT and listening paging messages in the same time unit of different initial DL BWPs.

[0155] Method 1: Prohibit the network from configuring downlink transmissions of paging messages and SDTs on different initial DL BWPs within the same time unit, or prevent the UE from expecting to receive paging messages and SDTs on different initial DL BWPs within the same time unit. This prohibition of the network configuring SDTs and paging messages on different initial DL BWPs within the same time unit, or the UE's expectation of not receiving paging messages and SDTs on different initial DL BWPs, can be achieved through the transmission configuration of SDTs and paging messages.

[0156] Receiving a paging message may include a wake-up signal of the UE before receiving the paging message, a paging message transmitted via PDCCH, and / or a paging message transmitted via PDSCH.

[0157] Receiving SDT may include: monitoring the search space that needs to be monitored after uplink transmission of SDT. The search space may include: the uplink Hybrid Automatic Repeat reQuest (HARQ) feedback PDCCH sent by PDCCH, as well as the subsequent downlink data scheduling PDCCH transmission and downlink data PDSCH transmission.

[0158] The above transmission configuration may include at least one of the following:

[0159] Method 1.1: The initial DL BWP for receiving paging messages and the initial DL BWP for receiving SDT messages must be on the same initial DL BWP.

[0160] Method 1.22: Allows paging message reception and SDT reception on different initial DL BWPs, but with different reception time units. Again, the SDT reception time unit and paging message listening time unit must include the delay for the UE to switch between different BWPs.

[0161] Method 2:

[0162] Based on network configuration, the UE determines which part of the information to receive first.

[0163] The network side (e.g., the radio access network side, which includes network devices such as base stations, but not limited to) can configure the transmission configuration for UE to receive SDT and paging messages based on current communication resources, network load, and / or system capacity. Simultaneously, the network side will also prioritize how to resolve conflicts when there is a conflict between UE receiving SDT and listening for paging messages. This priority will be configured and sent to the UE by the network side. Specifically, the network side configures the priority for conflicts when the time units for receiving SDT and paging messages partially or completely overlap, and the transmission BWP for SDT and the transmission BWP for paging messages are different initial DL BWPs.

[0164] Method 3: Priority-based settings, where the UE prioritizes receiving information or channels with higher priority. These priorities can be configured and assigned separately by different network sides.

[0165] 3.1: Prioritize based on BWP. For example, information transmitted on the first initial DL BWP has a higher priority than information transmitted on the second initial DL BWP (RedCap-specific initial DL BWP).

[0166] 3.2: Prioritize based on service type. For example, all SDT-related downlink transmissions have higher priority than paging-related downlink transmissions.

[0167] 3.3: Prioritize channels based on channel type. For example, the reception priority of all PDSCHs is higher than the monitoring priority of PDCCHs.

[0168] 3.4: Prioritize services based on their arrival time. For example, if the first downlink reception of a service is initiated first, subsequent receptions of that service have a higher priority than downlink receptions of other services. For instance, regarding paging reception, if the wake-up message is received earlier than the downlink feedback corresponding to the SDT uplink transmission, then before the paging PDSCH transmission ends, all paging-related downlink receptions have a higher priority than SDT downlink receptions.

[0169] 3.5: Define receiving priorities for different services and channels, as shown in the following two examples.

[0170]

[0172] It is worth noting that each element in Table 1 can be used alone or in combination with other elements in Table 1. Specific priority configurations for channels and services can include, but are not limited to, the examples in Table 1.

[0173] At the same time, it is worth noting that the "needs" mentioned in Method 1, Method 2 and Method 3 above are only used to distinguish different methods, and do not indicate which method is the preferred method or the more important method.
