Detailed Description

For ease of understanding, the terms referred to in this application are first introduced.

1. XR service

XR services are one of the types of services that the 5G system is to support, and XR includes augmented Reality (Augmented Reality, AR), virtual Reality (VR), cloud gaming (Cloud gaming), and so forth. XR traffic is typically characterized by a fixed frame rate, i.e. traffic arrives at the terminal device with a fixed period, but there is an additional delay Jitter (Jitter) above this fixed period, resulting in the actual data traffic arriving at the terminal device being either advanced or delayed. In one possible example, the fixed Frame rate may be 60 Frames Per Second (FPS), i.e., the fixed period is 16.67ms and the jitter range is [4, -4] ms. In actual 5G air interface transmission, the number of BITs (BITs) included in a frame may be large, and may be split into multiple TBs for transmission in multiple physical resources (e.g., multiple timeslots).

2. Discontinuous reception in radio resource control RRC connected state (ConnectedDiscontinuous Reception, C-DRX)

The R15 protocol has a C-DRX characteristic. The terminal device may be configured with a periodic on-off time domain pattern, and starts physical downlink control channel (Physical Downlink Control Channel, PDCCH) monitoring whenever an on duration is reached, and may enter a sleep state after the PDCCH monitoring is completed or after an off duration (off duration) is reached, so that energy may be saved. The C-DRX mechanism reduces unnecessary PDCCH monitoring by controlling the terminal equipment so as to achieve the energy-saving effect. But the C-DRX mechanism does not affect the reception of SPS PDSCH.

3、SPS PDSCH

SPS PDSCH is a PDSCH of semi-persistent transmission, is configured with periodic PDSCH transmission resources by higher layers, and is activated and deactivated using DCI, each PDSCH transmission of which does not require DCI scheduling except for activation and deactivation.

In order to better understand the method and device for transmitting and receiving the SPS PDSCH disclosed in the embodiments of the present application, a description is first given below of a communication system to which the embodiments of the present application are applicable.

Referring to fig. 1, fig. 1 is a schematic architecture diagram of a communication system according to an embodiment of the present application. The communication system may include, but is not limited to, one network device and one terminal device, and the number and form of devices shown in fig. 1 are only used as examples and not limiting to the embodiments of the present application, and may include two or more network devices and two or more terminal devices in practical applications. The communication system shown in fig. 1 is exemplified as including a network device 101 and a terminal device 102.

It should be noted that the technical solution of the embodiment of the present application may be applied to various communication systems. For example: a long term evolution (long term evolution, LTE) system, a fifth generation (5th generation,5G) mobile communication system, a 5G New Radio (NR) system, or other future new mobile communication systems, etc. It should also be noted that the side link in the embodiments of the present application may also be referred to as a side link or a through link.

The network device 101 in the embodiment of the present application is an entity on the network side for transmitting or receiving signals. For example, the network device 101 may be an evolved NodeB (eNB), a transmission point (transmission reception point, TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (wireless fidelity, wiFi) system, etc. The embodiment of the application does not limit the specific technology and the specific device form adopted by the network device. The network device provided in this embodiment of the present application may be composed of a Central Unit (CU) and a Distributed Unit (DU), where the CU may also be referred to as a control unit (control unit), and the structure of the CU-DU may be used to split the protocol layers of the network device, for example, a base station, where functions of part of the protocol layers are placed in the CU for centralized control, and functions of part or all of the protocol layers are distributed in the DU for centralized control of the DU by the CU.

The terminal device may also be referred to as a terminal device (terminal), a User Equipment (UE), a Mobile Station (MS), a mobile terminal device (MT), etc. The terminal device may be an automobile with a communication function, a smart car, a mobile phone (mobile phone), a wearable device, a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in unmanned-driving (self-driving), a wireless terminal device in teleoperation (remote medical surgery), a wireless terminal device in smart grid (smart grid), a wireless terminal device in transportation safety (transportation safety), a wireless terminal device in smart city (smart city), a wireless terminal device in smart home (smart home), or the like. The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the terminal equipment.

For XR traffic, if PDSCH is scheduled by dynamic scheduling, DCI scheduling is required for each PDSCH transmission. And the downlink XR service is transmitted by adopting an SPS PDSCH mechanism, so that the frequent transmission of DCI can be avoided, and the system capacity is enhanced. However, in order to quickly transmit XR service after XR service of each frame is reached, the period configuration of the SPS PDSCH is relatively short, for example, the period configuration is 1 time slot (slot), that is, there is SPS PDSCH resource in each slot for transmitting downlink data, and terminal equipment on each slot needs to monitor PDSCH, so that energy consumption of the terminal equipment is relatively high.

For XR services, or other services with a fixed period, the terminal device may perform the method described in any one of the embodiments of fig. 2 to 5, and the network device may perform the method described in any one of the embodiments of fig. 6 to 9.

It may be understood that, the communication system described in the embodiments of the present application is for more clearly describing the technical solution of the embodiments of the present application, and is not limited to the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the system architecture and the appearance of a new service scenario, the technical solution provided in the embodiments of the present application is equally applicable to similar technical problems.

It should be noted that, the method for transmitting and receiving the SPS PDSCH provided in any of the embodiments of the present application may be performed alone or in combination with possible implementation methods in other embodiments, and may also be performed in combination with any one of the technical solutions in the related art.

The following describes in detail a transmission and reception method of SPS PDSCH and a device thereof provided in the present application with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a method for receiving an SPS PDSCH according to an embodiment of the present application. The reception method of the SPS PDSCH is performed by a terminal device. As shown in fig. 2, the method may include, but is not limited to, the steps of:

step S201: SPS PDSCH transmitted by the network device is received in a designated receiving window.

In the embodiment of the present application, the terminal device may stop receiving the SPS PDSCH transmitted by the network device outside the specified reception window.

In the embodiment of the present application, the SPS PDSCH resources may be the first type of resources, that is, the terminal device may monitor the PDSCH only in each period of the SPS PDSCH resources within the specified reception window to receive the SPS PDSCH; and outside the appointed receiving window, stopping monitoring the PDSCH and stopping receiving the SPS PDSCH.

When the SPS PDSCH resources are resources of other categories than the first category, or the SPS PDSCH resources are not of a category, the reception of the SPS PDSCH is not limited by the designated reception window. That is, within and outside the designated reception window, the terminal device may monitor PDSCH in each period of SPS PDSCH resources to receive SPS PDSCH.

In the embodiment of the present application, the SPS PDSCH is activated by the activation information of the DCI. That is, before SPS PDSCH resources, the terminal device has activation information to receive DCI. That is, after the terminal device receives the activation information of the DCI, if there is a designated reception window before the deactivation information of the DCI is not received, monitoring the PDSCH in each period of SPS PDSCH resources within the designated reception window to receive the SPS PDSCH; after receiving the deactivation information of the DCI, the PDSCH is stopped being monitored, and the SPS PDSCH is stopped being received.

In the embodiment of the application, SPS PDSCH resources may be used to transmit XR traffic. Since SPS PDSCH does not require DCI scheduling, SPS PDSCH transmission mechanisms may be used to enhance system capacity to support more XR traffic. Because the XR service periodicity does not have downlink XR service data to be transmitted in every SPS PDSCH period, the network device may configure the terminal device with second indication information according to the downlink XR service data transmission condition to indicate a specified receiving window.

In the embodiment of the present application, the number of the designated receiving windows may be one or more.

According to the SPS PDSCH receiving method provided by the embodiment of the application, the terminal equipment can receive the SPS PDSCH sent by the network equipment in the appointed receiving window, so that the terminal equipment monitors the PDSCH only in each period in the appointed receiving window, the number of times that the terminal equipment monitors the PDSCH is reduced, and the energy consumption of the terminal equipment is reduced. Another benefit is that using a designated receive window to limit the reception of SPS PDSCH, the network device does not need to send DCI activation information and DCI deactivation information frequently for each XR service period, which is beneficial to reduce network overhead.

Referring to fig. 3, fig. 3 is a flowchart of another SPS PDSCH receiving method according to an embodiment of the present application. The reception method of the SPS PDSCH is performed by a terminal device. As shown in fig. 3, the method may include, but is not limited to, the steps of:

step S301: and receiving first indication information sent by the network equipment, wherein the first indication information is used for indicating SPS PDSCH resources to be resources of a first category.

In this embodiment of the present application, the first indication information is any one of the following: SPS PDSCH configuration information; activation information of DCI of SPS PDSCH resources; information other than SPS PDSCH configuration information and DCI activation information.

In one example, the terminal device may receive SPS PDSCH configuration information sent by the network device, where the SPS PDSCH configuration information may carry a first parameter for indicating that SPS PDSCH resources are resources of a first class. The SPS PDSCH configuration information is used to configure SPS PDSCH resources for the period and may also include at least one of the following parameters: the period of the SPS PDSCH, the index number of the physical uplink control channel (Physical Uplink Control Channel, PUCCH) resource used for HARQ feedback, MCS, etc. may be set according to actual needs.

In this example, the terminal device may receive SPS PDSCH configuration information transmitted by the network device, and if the activation information of the DCI is received, the terminal device may monitor the PDSCH to receive the SPS PDSCH in each period of SPS PDSCH resources within a designated reception window thereafter. It should be noted that, each time the activation information of the DCI is received, the terminal device may monitor the PDSCH in each period of the SPS PDSCH resource in the designated receiving window to receive the SPS PDSCH.

In another example, the terminal device may receive SPS PDSCH configuration information sent by the network device, and may then receive DCI activation information of the SPS PDSCH resource, where the DCI activation information may carry the first parameter. The activation information of the DCI is used to activate SPS PDSCH resources, and the SPS PDSCH resources after the indication may perform PDSCH transmission.

In this example, after receiving the activation information of the DCI carrying the first parameter, the terminal device listens to the PDSCH in each period of the SPS PDSCH resources within the designated reception window to receive the SPS PDSCH if the designated reception window exists before the deactivation information of the DCI is not received. If the activation information of the DCI received again does not carry the first parameter, the PDSCH is monitored to receive the SPS PDSCH in all periods of the SPS PDSCH resource before the deactivation information of the DCI is received again.

In another example, the terminal device may receive SPS PDSCH configuration information transmitted by the network device, may then receive activation information of DCI of SPS PDSCH resources, and may also receive the first indication information. The first indication information may carry a first parameter, and a receiving time point of the first indication information may be before or after or simultaneously with the DCI activation information, or before or simultaneously with the SPS PDSCH configuration information, which is not specifically limited herein, and may be set according to actual needs.

In this example, the reception of the first indication information is independent of the reception of the SPS PDSCH configuration information and the reception of the activation information of the DCI, and may be information other than the SPS PDSCH configuration information and the activation information of the DCI. In this example, after the terminal device receives the 3 pieces of information, if a specified reception window exists, the PDSCH is monitored for reception of the SPS PDSCH in each period of SPS PDSCH resources within the specified reception window.

Step S302: SPS PDSCH transmitted by the network device is received in a designated receiving window.

According to the SPS PDSCH receiving method provided by the embodiment of the application, the terminal equipment can receive first indication information sent by the network equipment, wherein the first indication information is used for indicating SPS PDSCH resources to be resources of a first category; and the SPS PDSCH sent by the network equipment is received in the appointed receiving window, so that the terminal equipment only monitors the PDSCH in each period in the appointed receiving window, the number of times that the terminal equipment monitors the PDSCH is reduced, and the energy consumption of the terminal equipment is reduced. Another benefit is that using a designated receive window to limit the reception of SPS PDSCH, the network device does not need to send DCI activation information and DCI deactivation information frequently for each XR service period, which is beneficial to reduce network overhead.

Referring to fig. 4, fig. 4 is a flowchart of another SPS PDSCH receiving method according to an embodiment of the present application. The reception method of the SPS PDSCH is performed by a terminal device. As shown in fig. 4, the method may include, but is not limited to, the steps of:

step S401: and receiving second indication information sent by the network equipment, wherein the second indication information is used for indicating the appointed receiving window.

In an example of the embodiment of the present application, the second indication information may be C-DRX configuration information, and the designated receiving window is an activation period corresponding to the C-DRX configuration information.

In this example, the activation period includes: the active period configured by the C-DRX configuration information, and the period in which the inactivity timer configured by the C-DRX configuration information does not timeout. Here, the inactivity timer mentioned here is an inactivity timer related to the SPS PDSCH; wherein, the inactivity timer and the inactivity timer related to the DCI may be the same or different.

Wherein the C-DRX configuration information is configured with a plurality of DRX cycles. An on period and an off period are included in each DRX cycle. And starting PDCCH monitoring in the working period, and entering a sleep state after the PDCCH monitoring is finished or the closing period arrives. The sum of the on period and the off period is one DRX cycle.

In this example, where SPS PDSCH resources are resources of the first class, the C-DRX configuration information may be used to indicate a specified receive window in which the SPS PDSCH resources may be received. Wherein, the starting time point of the appointed receiving window can be the starting time point of the working period; the closing time point of the designated receiving window may be the latest time point among the following time points: the time point when the inactivity timer expires, the end time point of the working period. The restart condition of the inactivity timer may include: DCI information is correctly received.

In this example, to avoid the case of the SPS PDSCH reception interruption, in the case where the SPS PDSCH resources are resources of the first category, the restart condition of the inactivity timer may further include: the SPS PDSCH is received correctly. That is, the inactivity timer is restarted when the SPS PDSCH is correctly received, and the starting period of the inactivity period is redetermined. The inactivity timer referred to herein is an inactivity timer related to SPS PDSCH; wherein, the inactivity timer and the inactivity timer related to the DCI may be the same or different. Wherein an active period and an inactive period are included in each DRX cycle. The sum of the active period and the inactive period is one DRX cycle.

In another example, the second indication information includes: configuration information of window opening information and configuration information of window closing information; configuration information of the window opening information is used for indicating the sending time-frequency position of the window opening information; the configuration information of the window closing information is used for indicating the sending time-frequency position of the window closing information; designating an opening time point of a receiving window as a receiving time point of window opening information; the closing time point of the receiving window is designated as the receiving time point of the window closing information.

In this example, the configuration information of the window opening information may include a transmission time-frequency position of the window opening information, etc., and the terminal device may monitor the window opening information at the transmission time-frequency position. The configuration information of the window closing information may include a transmission time-frequency position of the window closing information, and the terminal device may monitor the window closing information at the transmission time-frequency position. Wherein the window opening information and the window closing information are different information.

In another example, the second indication information includes: configuration information of window control information; configuration information of window control information is used for indicating the sending time-frequency position of the window control information; designating a receiving window as a time period between receiving time points of two adjacent window control information; when receiving the first window control information in the two adjacent window control information, designating the receiving window to be in a closed state.

In this example, the configuration information of the window control information may include a transmission time-frequency position of the window control information, etc., on which the terminal device may listen for the window control information. When the designated receiving window is in the closed state, the designated receiving window is opened, that is, the receiving time point of the window control information is taken as the opening time point of the designated receiving window. If the designated receiving window is in an open state, the window control information is received, and the designated receiving window is closed, namely, the receiving time point of the window control information is taken as the closing time point of the designated receiving window.

Step S402: SPS PDSCH transmitted by the network device is received in a designated receiving window.

In the embodiment of the application, SPS PDSCH resources may be used to transmit XR traffic. Wherein the number of designated receiving windows may be one or more.

According to the SPS PDSCH receiving method provided by the embodiment of the application, the terminal equipment can receive second indication information sent by the network equipment, wherein the second indication information is used for indicating a designated receiving window; and the SPS PDSCH sent by the network equipment is received in the appointed receiving window, so that the terminal equipment only monitors the PDSCH in each period in the appointed receiving window, the number of times that the terminal equipment monitors the PDSCH is reduced, and the energy consumption of the terminal equipment is reduced. Another benefit is that with the use of a designated receive window to limit the reception of SPS PDSCH, the network device does not need to send DCI activation information and DCI deactivation information frequently for each XR service period, which is beneficial to reduce network overhead.

Referring to fig. 5, fig. 5 is a flowchart of another SPS PDSCH receiving method according to an embodiment of the present application. The reception method of the SPS PDSCH is performed by a terminal device. As shown in fig. 5, the method may include, but is not limited to, the steps of:

step S501: and receiving first indication information sent by the network equipment, wherein the first indication information is used for indicating SPS PDSCH resources to be resources of a first category.

In an example, a terminal device may receive SPS PDSCH configuration information sent by a network device, where the SPS PDSCH configuration information may carry a first parameter for indicating SPS PDSCH resources as resources of a first class. In another example, the terminal device may receive SPS PDSCH configuration information sent by the network device, and may then receive DCI activation information of the SPS PDSCH resource, where the DCI activation information may carry the first parameter.

In another example, the terminal device may receive SPS PDSCH configuration information transmitted by the network device, may then receive activation information of DCI of SPS PDSCH resources, and may also receive the first indication information. The first indication information may carry a first parameter. In this example, the reception of the first indication information is independent of the reception of the SPS PDSCH configuration information and the reception of the activation information of the DCI, and may be information other than the SPS PDSCH configuration information and the activation information of the DCI.

Step S502: and receiving second indication information sent by the network equipment, wherein the second indication information is used for indicating the appointed receiving window.

In an example of the embodiment of the present application, the second indication information may be C-DRX configuration information, and the designated receiving window is an activation period corresponding to the C-DRX configuration information. In this example, the activation period includes: the active period configured by the C-DRX configuration information, and the period in which the inactivity timer configured by the C-DRX configuration information does not timeout. In this example, to avoid the case of the SPS PDSCH reception interruption, in the case where the SPS PDSCH resources are resources of the first category, the restart condition of the inactivity timer may further include: the SPS PDSCH is received correctly.

Here, the inactivity timer mentioned here is an inactivity timer related to the SPS PDSCH; wherein, the inactivity timer and the inactivity timer related to the DCI may be the same or different.

Step S503: SPS PDSCH transmitted by the network device is received in a designated receiving window.

Note that, the sequence of step S501 and step S502 is not limited. Step S501 may be performed first, and then step S502 may be performed; alternatively, step S502 may be performed first, and then step S501 may be performed; alternatively, step S501 and step S502 may be performed simultaneously.

According to the SPS PDSCH receiving method provided by the embodiment of the application, the terminal equipment can receive first indication information sent by the network equipment, wherein the first indication information is used for indicating SPS PDSCH resources to be resources of a first category; receiving second indication information sent by the network equipment, wherein the second indication information is used for indicating a designated receiving window; and the SPS PDSCH sent by the network equipment is received in the appointed receiving window, so that the terminal equipment only monitors the PDSCH in each period in the appointed receiving window, the number of times that the terminal equipment monitors the PDSCH is reduced, and the energy consumption of the terminal equipment is reduced. Another benefit is that with the use of a designated receive window to limit the reception of SPS PDSCH, the network device does not need to send DCI activation information and DCI deactivation information frequently for each XR service period, which is beneficial to reduce network overhead.

Referring to fig. 6, fig. 6 is a flowchart of a method for transmitting an SPS PDSCH according to an embodiment of the present application. The SPS PDSCH transmission method is performed by a network device. As shown in fig. 6, the method may include, but is not limited to, the steps of:

Thus, the network device may transmit the SPS PDSCH to the terminal device for only at least one period of SPS PDSCH resources within the designated receive window.

When the SPS PDSCH resources are resources of other categories than the first category, or the SPS PDSCH resources are not of a category, the reception of the SPS PDSCH is not limited by the designated reception window.

Thus, the network device may transmit SPS PDSCH to the terminal device within the designated reception window and within at least one period of SPS PDSCH resources outside the designated reception window.

In the embodiment of the present application, the SPS PDSCH is activated by the activation information of the DCI. That is, before the SPS PDSCH resources, the network device may transmit activation information of DCI to the terminal device to activate the SPS PDSCH, i.e., may transmit the SPS PDSCH to the terminal device using the SPS PDSCH resources.

According to the SPS PDSCH sending method provided by the embodiment of the application, the network equipment can send the SPS PDSCH to the terminal equipment in the appointed receiving window, so that the terminal equipment can monitor the PDSCH only in each period in the appointed receiving window, the number of times that the terminal equipment monitors the PDSCH is reduced, and the energy consumption of the terminal equipment is reduced. In addition, the designated receiving window is used for limiting the receiving of the SPS PDSCH at the terminal equipment side, so that network equipment does not need to frequently send DCI activation information and DCI deactivation information for each XR service period, and network overhead is reduced.

In another example, the network device may send SPS PDSCH configuration information to the terminal device, may then send DCI activation information for SPS PDSCH resources to the terminal device, and may also send first indication information to the terminal device.

In this example, to avoid the case of the SPS PDSCH reception interruption, in the case where the SPS PDSCH resources are resources of the first category, the restart condition of the inactivity timer may further include: the SPS PDSCH is received correctly.
