DOWNLINK TRANSMISSION CONFIGURATION AND RECEIVING METHODS AND APPARATUSES, COMMUNICATION DEVICE AND STORAGE MEDIUM

TECHNICAL FIELD

The present disclosure relates to the field of wireless communication technologies, but is not limited to the field of wireless communication technologies, and in particular to a downlink transmission configuration method and apparatus, a downlink transmission receiving method and apparatus, a communication device and a storage medium.

BACKGROUND

In the 4th generation (4G) mobile communication system of long term evolution (LTE), two major technologies including machine type communication (MTC) and narrow band internet of things (NB IoT) have been proposed to support IoT services. These two technologies are mainly aimed at low speed, high latency and other scenarios. For example, in scenarios such as meter reading and environmental monitoring. At present, the NB IoT can only support a speed of up to a few hundred Kb/s, and the MTC can only support a speed of up to a few Mb/s. With the continuous development of IoT services, for example, the popularity of these services such as video surveillance, smart homes, wearable devices, and industrial sensor monitoring, these services typically require speeds ranging from 10 Mb/s to 100 Mb/s and also have relatively high latency requirements. However, it is difficult for the MTC technology and the NB IoT technology in the LTE to meet these requirements.

Based on this situation, a new type of user equipment in a new air port of a 5th generation (5G) mobile communication system is proposed in the related art to cover the requirements of mid-range IoT devices. This new type of user equipment is called a reduced capability user equipment (Redcap UE) or a new radio lightweight terminal (NR-lite).

In an embodiment, the wireless communication system may also be a 5G system, which is also called new radio (NR) system or 5G NR system. In an embodiment, the wireless communication system may also be a next generation system of the 5G system. An access network in the 5G system may be referred to as New Generation-Radio Access Network (NG-RAN); or it is an MTC system.

The access device 12 may be an evolved access device (eNB) employed in the 4G system. In an embodiment, the access device 12 may also be an access device adopting centralized distributed architecture (gNB) in the 5G system. When adopting the centralized distributed architecture, the access device 12 usually includes a central unit (CU) and at least two distributed units (DU).

Alternatively, the network management device may also be another core network device, such as Serving GateWay (SGW), Public Data Network GateWay (PGW), Policy and Charging Rules Function (PCRF), or Home Subscriber Server (HSS) or the like. The implementation morphology of the network management device 13 is not limited in the embodiments of the present disclosure.

As shown in FIG. 2A, an embodiment of the present disclosure provides a downlink transmission configuration method, which is performed by an access device. The method includes the following step S110.

At step S110, a small data transmission (SDT) and a paging message for a preset type of user equipment (UE) are configured on a same initial downlink (DL) bandwidth part (BWP), or on different time units of different initial downlink (DL) bandwidth parts (BWPs).

The access device may include any device within an access network, for example, the access device may specifically be a base station.

For example, the preset type of UE may be any UE that does not support receiving data at once on two or more initial DL BWPs, or does not expect to receive data at once on two or more initial DL BWPs.

The preset type of UE includes, but is not limited to, a reduced capability (Redcap) UE.

The Redcap UE, similar to the IoT device in the LTE, is typically based on a 5G new radio lightweight terminal (NR-lite) and typically needs to meet the following requirements: low cost, low complexity, some coverage enhancement, and power savings. The UE is indicated to support smaller bandwidths, e.g., limited to 5M Hz or 10M Hz, or to limit the size of the NR-lite buffer, and thus the size of the transmission block per receipt, etc. The UE can be optimized for power savings. Possible optimizations for power savings may simplifying the communication process, and reducing the number of times the NR-lite user has to detect the downstream control channel, etc.

The SDT herein includes at least the downlink transmission of the SDT. The downlink transmission of the SDT may include feedback of the uplink transmission of the SDT, transmission scheduling, and/or physical downlink shared channel (PDSCH) transmission. The feedback of the uplink transmission of the SDT includes, but is not limited to, hybrid automatic repeat request (HARQ) feedback sent by the physical downlink control channel (PDCCH). The HARQ feedback may include acknowledgment (ACK) feedback indicating successful transmission and/or non acknowledgment (NACK) feedback. The HARQ feedback can be based on transmission block (TB) or code block group (CBG).

The transmission scheduling includes, but is not limited to, at least one of PDCCH scheduling, physical uplink control channel (PUCCH) scheduling, PDSCH scheduling, or PUSCH scheduling transmitted through PDCCH.

Configuration information for configuring the SDT and the paging message for the preset type of UE on the same initial DL BWP or different time units of different initial DL BWPs can be transmitted to the preset type of UE through various message, for example, through a system message, a radio resource control (RRC) message, or a medium access control (MAC) control element (CE) message, etc. Of course, this is only an example, and the implementation is not limited thereto.

For example, as shown in FIG. 2B, an embodiment of the present disclosure provides a downlink transmission configuration method, which may include the following step S110A.

At step S110A, the SDT and the paging message for the preset type of UE are configured on the same initial DL BWP.

If the SDT and the paging message are configured on the same initial DL BWP, the preset type of UE can receive the SDT and the paging message on the same time unit and/or different time units on an initial DL BWP.

As shown in FIG. 2C, an embodiment of the present disclosure provides a downlink transmission configuration method, which may include the following step S110B.

At step S110B, the SDT and the paging message for the preset type of UE are configured on different time units on different initial DL BWPs.

If the SDT and the paging message for the preset type of UE are configured on different time units on different initial DL BWPs, the preset type of UE can switch to the initial DL BWP for transmitting the SDT or to the initial DL BWP for transmitting the paging message on the corresponding time unit.

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

In some embodiments, the step S110B may include: based on a duration required for the preset type of UE to switch between different BWPs, the SDT and the paging message are configured on the different units of the different initial DL BWPs, where a time interval between a time unit for the SDT and a time unit for the paging message is greater than or equal to the duration required for the preset type of UE to switch between the different BWPs.

The time interval between the time unit for receiving the SDT and the time unit for listening to the paging message needs to be greater than or equal to the duration required for the preset type of UE to switch between the different BWPs. Therefore, it can be ensured that the preset type of UE is able to successfully listen to the paging message and receive the SDT on different time units of different initial DL BWPs.

In some embodiments, the preset type of UE may include at least one of: a reduced capability UE; a UE which is prohibited from configuring the SDT and the paging message on a same time unit of the different initial DL BWPs; or a UE which does not expect to configure the SDT and the paging message on a same time unit of the different initial DL BWPs.

The reduced capability UE herein is the aforementioned Redcap UE.

In some embodiments, communication standard protocols or private protocols or communication carriers, etc., predetermine that: some UEs have downlink transmissions of SDTs and paging message cooperating with UEs on the same time unit of different initial DL BWPs, or UEs themselves report UEs that do not expect to configure the SDTs and the paging message on the same time unit of different initial DL BWPs.

As shown in FIG. 3A, an embodiment of the present disclosure provides a downlink transmission receiving method, which is performed by a preset type of UE. The method may include the following step S210.

At step S210, SDT and a paging message are received on a same initial DL BWP, or on different time units of different initial DL BWPs.

The preset type of UE herein may be: a reduced capability UE, where the reduced capability UE herein is the aforementioned Redcap UE; a UE which is prohibited from configuring the SDT and the paging message on a same time unit of the different initial DL BWPs; or a UE which does not expect to configure the SDT and the paging message on a same time unit of the different initial DL BWPs.

As shown in FIG. 3B, an embodiment of the present disclosure provides a downlink transmission receiving method, which may include the following step S210A.

At step S210A, the SDT and the paging message are received on the same initial DL BWP.

The preset type of UE receives the SDT and the paging message on the same initial DL BWP, so that the preset type of UE can receive the SDT and listen to the paging message on the same time unit or different time units without switching the initial DL BWP.

As shown in FIG. 3C, an embodiment of the present disclosure provides a downlink transmission receiving method, which may include the following step S210B.

At step S210B, the SDT and the paging message are received on different time units of different initial DL BWPs.

The preset type of UE receives the SDT and listens to the paging message on different initial DL BWPs. This can solve the failure of SDT receipt and/or the failure of listening to the paging message caused by the preset type of UEs that does not support or does not expect to receive the SDT and listen to the paging message on the same time unit of different initial DL BWPs.

In some embodiments, the time interval between a time unit for the SDT and a time unit for the paging message is greater than or equal to the duration required for the preset type of UE to switch between the different BWPs. That is, the time interval between the time unit for receiving the SDT and the time unit for listening to the paging message is greater than or equal to the duration required for the preset type of UE to switch between the different BWPs.

The preset type of UE may include one or more communication modules. For example, the preset type of UE has a communication module. The communication module may include an antenna and a radio frequency (RF) circuit connected to the antenna. After working parameters of the communication module are adjusted, the communication module can only transmit and receive signals corresponding to BWP transmission. For example, the working parameters include, but are not limited to, a length of array of the antenna, etc. Of course, these are examples, and any known parameters could be used.

As an example, the preset type of UE has multiple communication modules. Due to the power consumption and/or load considerations of UE, at a given time, the preset type of UE may have only one communication module in operation, and other communication modules may be in non-operating states such as off or sleep. If the preset type of UE switches to a communication module in working mode to switch to an initial DL BWP in working, this also requires some switching time.

Considering the time required for the preset type of UE to switch to the initial DL BWP in working, the downlink transmission of the SDT and the paging message of the preset type of UE are configured on different initial DL BWPs. Firstly, the time unit for the preset type of UE for receiving the SDT and the time unit for the predefined type of UE for listening to the paging message will be configured on different time domain resources. Secondly, the time interval between the time unit for receiving the SDT and the time unit for listening to the paging message also needs to be at least equal to or even greater than the duration required for the preset type of UE to switch between different initial DL BWPs, such that the success rate of receiving the SDT and the success rate of listening to the paging message for the predetermined type of UE are in order to ensured.

As shown in FIG. 4, an embodiment of the present disclosure provides a downlink transmission receiving method, which is performed by a preset type of UE. The method may include the following step S310.

At step S310, in response to a conflict between a time unit for receiving SDT and a time unit for listening to a paging message, based on a priority, the SDT is received or the paging message is listened.

In some embodiments, if the preset type of UE detects a conflict between the time unit for receiving the SDT and the time unit for listening to the paging message, whether to receive the SDT or listen to the paging message based on the priority will be determined. Therefore, the network side may not need to consider this conflict when configuring the time unit for receiving the SDT and the time unit for listening to the paging message for the preset type of UE.

The conflict between the time unit for receiving SDT and the time unit for listening to the paging message herein includes, but is not limited to that: the time unit for receiving the SDT and the time unit for listening to the paging message are on the same time unit of different initial DL BWPs; and/or, the time unit for receiving the SDT and the time unit for listening to the paging message are on the first time unit and the second time unit of different initial DL BWPs, respectively, and the time interval between the first time unit and the second time unit is smaller than the duration required for the preset type of UE to switch between different initial DL BWPs.

The mentioned embodiments are only examples of the time unit for receiving the SDT and the time unit for listening to the paging message, and the specific implementation is not limited thereto.

In some embodiments, the priority may be a special priority set specifically to resolve the conflict between the time unit for receiving the SDT and the time unit for listening to the paging message for the preset type of UE.

In other embodiments, the priority may be a shared other priority to resolve the conflict between the time unit for receiving the SDT and the time unit for listening to the paging message. The shared priority may include: a priority of any transmission parameter or attribute of the preset type of UE for receiving the SDT and the paging message. For example, the shared priority may be: a priority for channel based on the transmission channel of the SDT and the transmission channel of the paging message, and the like. If other priority is shared, the network side does not need to set a priority specifically for resolving the conflict between the time unit for receiving the SDT and the time unit for listening to the paging message for the preset type of UE, such that the signaling overhead and the configuration operation of the network side are reduced.

In some embodiments, the priority includes at least one of: a priority configured by a network side; or a predefined priority.

The priority configured by a network side may be a special priority and/or a shared priority.

The predefined priority may be a special priority and/or a shared priority. For example, the predefined priority may include a priority predefined in a standard protocol or a private protocol, or a priority pre-established in a base station or a UE, etc.

In some embodiments, the priority includes at least one of: a priority for BWP; a priority for service type; a priority for channel; a priority for arrival time, where an arrival time is positively related to a priority; or a priority for service and channel.

In some embodiments, when the time unit for receiving the SDT and the time unit for listening to the paging message for the preset type of UE are on different initial DL BWPs, whether to prioritize the receiving the SDT or to prioritize the listening to the paging message can be determined directly based on the priority configured by a network side or the predefined priority of the initial DL BWP.

For example, if the priority of the initial DL BWP on which the time unit for receiving the SDT is higher than the priority of the initial DL BWP on which the time unit for listening to the paging message is, the preset type of UE will, in case of the above-mentioned conflict, prioritize the receiving the SDT. If the priority of the initial DL BWP on which the time unit for receiving the SDT is lower than the priority of the initial DL BWP on which the time unit for listening to the paging message is, the preset type of UE will, in case of the above-mentioned conflict, prioritize the listening to the paging message.

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

In an embodiment, the SDT relates to a data transmission, and the paging message is configured for paging the UE to enable the UE to switch from an RRC non-connected state to an RRC connected state. The RRC non-connected state includes, but is not limited to: an RRC idle state and/or an RRC inactive state. The paging message may be sent by one or more paging occasions (POs). The priority for service of all SDTs may be set to be higher than the priority for service of the paging message.

In another embodiment, the priority for service may be set based on the service content of the SDT, e.g., the service content of the SDT includes that: ultra reliable and low latency communication (URLLC) and enhanced mobile broadband (eMBB), where the service priority of the URLLC may be higher than that of the eMBB. In this case, when the preset type of UE finds that the time unit for receiving the SDT conflicts with the time unit for listening to the paging message, it will prioritize the receiving the SDT without listening to the paging message if the service content of the SDT is the URLLC; and it will prioritize the listening to the paging message without receiving the SDT if the service content of the SDT is the eMBB.

The channel for transmitting the SDT and the channel for transmitting the paging message both include PDSCH and/or PDCCH. In some embodiments, different downlink channel configurations have different channel priorities, and the preset type of UE may directly multiplex the priority for channels on which the SDT and the paging message are into a priority for resolving the conflict between the time unit for receiving the SDT and the time unit for listening to the paging message. In some embodiments, there is overlap between the time unit for the SDT and the time unit for the paging message, but only partial overlap or the time interval is less than the duration required for the preset type of UE to switch between different initial DL BWPs. Therefore, there is still a distinction between the time unit for the SDT and the time unit for the paging message. The arrival time herein refers to a starting time of the time unit for receiving the SDT and the time unit for listening to the paging message, and there is the conflict between the time unit for receiving the SDT and the time unit for listening to the paging message. In this embodiment, the arrival time is positively related to a priority, that is, the earlier the arrival time, the higher the priority, and the later the arrival time, the lower the priority. In this case, when the preset type of UE detects the conflict, if the arrival time of the time unit for receiving the SDT is earlier than that of the time unit for listening to the paging message, the priority will be given to the receiving the SDT; if the arrival time of the time unit for receiving the SDT is later than that of the time unit for listening to the paging message, the priority will be given to listening to the paging message. When the preset type of UE detects the conflict, if the arrival time of time unit for receiving the SDT and that of the time unit for listening to the paging message are the same, it can determine whether to prioritize the receiving the SDT or the listening to the paging message based on other priority, alternatively, randomly select or follow a preset setting to prioritize the receiving the SDT or the listening to the paging message.

In the embodiments the present disclosure, the priority for service and channel is a priority that simultaneously considers both the channel type and the service type, so that when resolving the aforementioned conflict, the preset type of UE can simultaneously consider both the channel and the service, thereby the communication quality of the preset type of UE is improved.

For example, regarding a priority for service type, the priority for service type of the SDT is higher than the priority for service type of the paging message. If the priority for service of the SDT is higher than that of the paging message, the preset type of UE will receive the SDT first and determine the transmission of service data first.

In some embodiments, regarding a priority for channel, the priority for channel of the PDSCH is higher than that of the PDCCH, alternatively, the priority for channel of the PDSCH is lower than that of the PDCCH.

The channel for transmitting the SDT and the channel for transmitting the paging message can both be a PDSCH and/or a PDCCH.

In an 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.

For example, regarding the priority for service and channel, there is at least one of the following: for PDCCH transmission of the SDT, a priority of the SDT is higher than a priority of a wake-up signal of the paging message; for the PDCCH transmission of the SDT, the priority of the SDT is higher than a priority of the PDCCH transmission of the paging message; for the PDCCH transmission of the SDT, the priority of the SDT is higher than a priority of PDSCH transmission of the paging message; for PDSCH transmission of the SDT, the priority of the wake-up signal of the paging message is higher than the priority of the SDT; for the PDSCH transmission of the SDT, a priority of PDCCH transmission of the paging message is higher than the priority of the SDT; or for the PDSCH transmission of the SDT, the priority of the SDT is higher than the priority of the PDSCH transmission of the paging message.

In some embodiments, the preset type of UE simultaneously considers both channel priority and service priority, thereby determining from two aspects whether to prioritize the receiving the SDT or the listening to the paging message when the time unit for receiving the SDT conflicts with the time unit for listening to the paging message.

The wake-up signal of the paging message is generally transmitted at a point in time prior to the transmitting the paging message to indicate that the preset type of UE needs to listen to the paging message corresponding to the wake-up signal.

As shown in FIG. 5, an embodiment of the present disclosure provides a downlink transmission configuration method, which is performed by an access device, and the method includes the following step S410.

At step S410, a network side configuration is transmitted, where the network side configuration indicates a priority, and the priority is configured to, for a preset type of user equipment, resolve a conflict between a time unit for receiving small data transmission and a time unit for listening to a paging message.

The access device includes, but is not limited to: a base station, etc.

The network side configuration can resolve the conflict between the time unit for receiving the SDT and the time unit for listening to the paging message mentioned in any of the aforementioned embodiments by explicitly indicating and/or implicitly indicating a preset type of UE.

The network side configuration may be broadcast, multicast, or unicast.

For example, the network side configuration can be carried in a system information block (SIB). The SIB may be a main message block or any SIB other than the main message block. By means of broadcasting, the preset type of UE may preferably know how to resolve the conflict between the time unit for the SDT and the time unit for the paging message when the preset type of UE has not yet been connected to the cell.

In some embodiments, the network side configuration includes: a SIB configuration; a RRC configuration; a MAC CE configuration; and a downlink control information (DCI) configuration.

The SIB configuration means the network side configuration carried in the SIB.

The RRC configuration means the network side configuration carried in any type of RRC message.

The MAC CE configuration means the network side configuration carried in the MAC CE.

The DCI configuration means the network side configuration carried in the DCI.

The embodiments of the present disclosure provide a method for receiving SDT and listening to a paging message, which is configured to solve the problem that a preset type of UE cannot simultaneously receive the SDT and listen to the paging message on the same time unit of different initial DL BWPs.

Mode 1:

The network is prohibited from appearing at the same time unit to allow the UE to receive the paging message and the downlink transmission of the SDT on different initial DL BWPs, or the UE does not expect to receive the paging message and the SDT on the same time unit of different initial DL BWPs. The fact that the network is prohibited from configuring the SDT and the paging message on the same time unit of different initial DL BWPs, or that the UE does not expect to receive the paging message and the SDT on different initial DL BWPs, can be realized by the transmission configuration of the SDT and the paging message.

Receiving the paging message may include receiving a wake-up signal from the UE before receiving a paging message, a paging message transmitted by the PDCCH, and/or a paging message transmitted by the PDSCH.

Receiving the SDT can include: monitoring a search space that needs to be monitored after uplink transmission for the SDT. The search space may include: an uplink hybrid automatic repeat request (HARQ) feedback PDCCH sent by the PDCCH, as well as scheduling PDCCH transmission for the downlink data, and PDSCH transmissions for the downlink data.

The above-mentioned transmission configuration may include at least one of Mode 1.1 or Mode 1.2.

- Mode 1.1, the initial DL BWP for receiving the paging message and the initial DL BWP for receiving the SDT need to be on the same initial DL BWP.
- Mode 1.2, receiving the paging message and receiving the SDT on different initial DL BWPs are allowed, but with different time units. The receiving time unit for the SDT and the listening time unit for the paging message also need to include a delay for the UE to switch between the different BWPs.

Mode 2:

The UE decides which information is prioritized to be received based on the network side configuration.

The network side (e.g., a radio access network side, the radio access network side includes a network device including but being not limited to an access device such as a base station), may configure the transmission configuration for the UE to receive the SDT and the paging message based on the current communication resources, the network load and/or the system capacity, etc., and when there is a conflict between receiving the SDT and listening to the paging message, the network side also configures the priority of how to resolve the conflict. This priority will be transmitted to the UE through the network side configuration. That is, when the time unit for the SDT and the time unit for the paging message partially or completely overlap, and the transmission BWP for the SDT and the transmission BWP for the paging message are different initial DL BWP, the network side configures the priority for the conflict.

Mode 3:

Based on the priority, a message or a channel with high priority are received by the UE first. The priority herein can be specifically indicated by different network side configurations.

- 3.1, the priority is set based on a BWP. For example, a message transmitted on the first initial DL BWP has a higher priority than a message transmitted on the second initial DL BWP (RedCap-specific initial DL BWP).
- 3.2, the priority is set based on a service type. For example, all downlink transmissions related to the SDT have higher priority than the downlink transmission related to the paging message.
- 3.3, the priority is set based on a channel type. For example, the receiving of all PDSCH has a higher priority than the monitoring of the PDCCH.
- 3.4, the priority is set based on an arrival time for service. For example, if the first downlink receipt of a service is started first, the subsequent receipt of this service is prioritized over the downlink receipt of other service. For example, for the receipt of the paging message, if the wake-up message is received earlier than the downlink feedback corresponding to the SDT, all downlink receipts related to the paging message are prioritized over the downlink receipt of the SDT until the end of the PDSCH transmission of the paging message.
- 3.5, the receipt priorities are defined for different services, channels, etc., and two examples are shown in Table 1.
