XR includes augmented reality (Augmented Reality, AR), virtual reality (Virtual Reality, VR), cloud gaming (Cloud gaming), etc. A typical feature of XR services is that there is a fixed frame rate, that is, there is a fixed period for the service to arrive at the terminal device, but there will be additional delay jitter (Jitter) above the fixed period, resulting in some differences in the actual data service arriving at the terminal device. Advance or delay. In a possible example, the fixed frame rate can be 60 frames per second (FPS), that is, the fixed period is 16.67ms, and the jitter range is [4,-4]ms. In actual 5G air interface transmission, the number of bits (Binary digits, BIT) contained in a frame may be large, and it will be split into multiple TBs and transmitted in multiple physical resources (such as multiple time slots).

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

There is C-DRX feature in R15 protocol. The terminal equipment can be configured with a periodic on-off time domain pattern. Whenever the working period (on duration) is reached, the physical downlink control channel (Physical Downlink Control Channel, PDCCH) monitoring is turned on. When the PDCCH monitoring is completed or the off duration (off duration) is enabled, ) arrives, it goes to sleep, thus saving energy. The C-DRX mechanism achieves energy saving by controlling terminal equipment to reduce unnecessary PDCCH monitoring. However, the C-DRX mechanism will not affect the reception of SPS PDSCH.

3. SPS PDSCH

SPS PDSCH is a semi-persistent PDSCH. The higher layer configures periodic PDSCH transmission resources and uses DCI activation and deactivation. In addition to activation and deactivation, each PDSCH transmission does not require DCI scheduling.

In actual applications, two or more devices may be included. Network equipment, two or more terminal devices. The communication system shown in Figure 1 includes a network device 101 and a terminal device 102 as an example.

For example: long term evolution (LTE) system, fifth generation (5th generation, 5G) mobile communication system, 5G new radio (NR) system, or other future new mobile communication systems. It should also be noted that the side link in the embodiment of the present application may also be called a side link or a through link.

Among them, for XR services, if dynamic scheduling is used to schedule PDSCH, DCI scheduling is required for each PDSCH transmission. Using the SPS PDSCH mechanism to transmit downlink XR services can avoid frequently sending DCI and enhance system capacity. However, in order to quickly transmit XR services after the XR services of each frame are reached, the cycle of SPS PDSCH is configured relatively short. For example, the cycle is configured as 1 time slot (slot), that is, there is SPS PDSCH in each slot. The resources are used to transmit downlink data.

It can be understood that the communication system described in the embodiments of the present application is to more clearly illustrate the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application. As those of ordinary skill in the art will know, With the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

It should be noted that the SPS PDSCH sending and receiving method provided in any embodiment of this application can be executed alone, or in combination with possible implementation methods in other embodiments, or in combination with any of the related technologies. Technical solutions are implemented together.

The SPS PDSCH sending and receiving method and its device provided by this application will be introduced in detail below in conjunction with the accompanying drawings.

Please refer to Figure 2. Figure 2 is a schematic flow chart of a SPS PDSCH receiving method provided by an embodiment of the present application. The SPS PDSCH receiving method is performed by the terminal equipment. As shown in Figure 2, the method may include but is not limited to the following steps:

Step S201: Receive the SPS PDSCH sent by the network device in the designated receiving window.

In the embodiment of this application, outside the designated receiving window, the terminal device can stop receiving the SPS PDSCH sent by the network device.

In the embodiment of the present application, the SPS PDSCH resource may be a first category resource, that is, the terminal device may only monitor the PDSCH in each cycle of the SPS PDSCH resource within the designated reception window to receive the SPS PDSCH; and in the designated reception window Outside the window, stop monitoring PDSCH and stop receiving SPS PDSCH.

When the SPS PDSCH resource is a resource of a category other than the first category, or the SPS PDSCH resource has no category, the reception of the SPS PDSCH will not be restricted by the designated reception window. That is to say, within the designated reception window and outside the designated reception window, the terminal device can monitor the PDSCH in each cycle of the SPS PDSCH resource to receive the SPS PDSCH.

In the embodiment of this application, SPS PDSCH is activated by DCI activation information. That is, before the SPS PDSCH resource, the terminal equipment receives DCI activation information. That is to say, after the terminal device receives the DCI activation information and before receiving the DCI deactivation information, if there is a designated receiving window, it will monitor the PDSCH in each cycle of the SPS PDSCH resource within the designated receiving window. To receive SPS PDSCH; after receiving the deactivation information of DCI, stop monitoring PDSCH and stop receiving SPS PDSCH.

In the embodiment of this application, SPS PDSCH resources can be used to transmit XR services. Since SPS PDSCH does not require DCI scheduling, the SPS PDSCH transmission mechanism can be used to enhance system capacity to support more XR services. Due to the periodicity of the XR service, there is not downlink XR service data to be transmitted in every SPS PDSCH cycle. Therefore, the network device can configure the second indication information for the terminal device according to the transmission situation of the downlink XR service data. to indicate the specified receive window.

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

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

Please refer to Figure 3. Figure 3 is a schematic flow chart of another SPS PDSCH receiving method provided by an embodiment of the present application. The SPS PDSCH receiving method is performed by the terminal equipment. As shown in Figure 3, the method may include but is not limited to the following steps:

Step S301: Receive first indication information sent by the network device. The first indication information is used to indicate that the SPS PDSCH resource is a resource of the first category.

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

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

In this example, the terminal device can receive the SPS PDSCH configuration information sent by the network device. If the DCI activation information is received, the terminal device can monitor the PDSCH in each cycle of the SPS PDSCH resource in the subsequent designated reception window to Receive SPS PDSCH. It should be noted that every time the activation information of DCI is received, the terminal device can monitor the PDSCH in each cycle of the SPS PDSCH resource in the subsequent designated reception window to receive the SPS PDSCH.

In another example, the terminal device can receive the SPS PDSCH configuration information sent by the network device, and then can receive DCI activation information of the SPS PDSCH resource, where the DCI activation information can carry the first parameter. Among them, the DCI activation information is used to activate SPS PDSCH resources and indicate that subsequent SPS PDSCH resources can be used for PDSCH transmission.

In this example, after the terminal device receives the DCI activation information carrying the first parameter and before receiving the DCI deactivation information, if there is a designated reception window, each SPS PDSCH resource within the designated reception window During the period, listen to PDSCH to receive SPS PDSCH. It should be noted that if the DCI activation information received again does not carry the first parameter, the PDSCH will be monitored in all cycles of the SPS PDSCH resource before the DCI deactivation information is received again to receive the SPS PDSCH.

In another example, the terminal device can receive the SPS PDSCH configuration information sent by the network device, and then can receive the DCI activation information of the SPS PDSCH resource, and the terminal device can also receive the first indication information. The first indication information may carry the first parameter, and the reception time point of the first indication information may be before, after, or at the same time as the DCI activation information, or before or at the same time as the SPS PDSCH configuration information. There is no specific limit here. 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 DCI activation information, and may be information other than the SPS PDSCH configuration information and the DCI activation information. In this example, after the terminal device receives the three pieces of information, if there is a designated reception window, it will listen to the PDSCH in each cycle of the SPS PDSCH resource within the designated reception window to receive the SPS PDSCH.

Step S302: Receive the SPS PDSCH sent by the network device in the designated receiving window.

In the SPS PDSCH receiving method provided in the embodiment of this application, the terminal device can receive the first indication information sent by the network device. The first indication information is used to indicate that the SPS PDSCH resource is a resource of the first category; the network device receives the SPS PDSCH resource in the designated receiving window. The SPS PDSCH is sent, so that the terminal device only monitors the PDSCH in each cycle within the specified receiving window, reducing the number of times the terminal device monitors the PDSCH and reducing the energy consumption of the terminal device. Another benefit is that by using a designated reception window to limit the reception of SPS PDSCH, network equipment does not need to frequently send DCI activation information and DCI deactivation information for each XR service cycle, which is beneficial to reducing network overhead.

Please refer to Figure 4, which is a schematic flow chart of another SPS PDSCH receiving method provided by an embodiment of the present application. The SPS PDSCH receiving method is performed by the terminal equipment. As shown in Figure 4, the method may include but is not limited to the following steps:

Step S401: Receive second indication information sent by the network device, where the second indication information is used to indicate a designated receiving window.

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

In this example, the activation time period includes: the working period configured in the C-DRX configuration information, and the period in which the inactivation timer configured in the C-DRX configuration information has not expired. Among them, it should be noted that the inactivation timer mentioned here is the inactivation timer related to SPS PDSCH; wherein, the inactivation timer and the inactivation timer related to DCI can be the same or different. .

Among them, the C-DRX configuration information is configured with multiple DRX cycles. Includes working period and off period in each DRX cycle. Among them, PDCCH monitoring is turned on during the working period, and the sleep state can be entered when the PDCCH monitoring ends or the shutdown period arrives. The sum of the working period and the off period is one DRX cycle.

In this example, when the SPS PDSCH resource is a resource of the first category, the C-DRX configuration information can be used to indicate a designated reception window in which the SPS PDSCH resource can be received. Among them, the starting time point of the designated receiving window can be the starting time point of the working period; the closing time point of the designated receiving window can be the latest time point among the following time points: the time point when the inactivation timer expires, the time point of the working period end time point. Among them, the restart condition of the inactivation timer may include: correctly receiving DCI information.

In this example, in order to avoid interruption of SPS PDSCH reception, when the SPS PDSCH resource is a resource of the first category, the restart condition of the inactivation timer may also include: correctly receiving the SPS PDSCH. That is to say, when the SPS PDSCH is correctly received, the inactivation timer will be restarted and the starting time period of the inactivation period will be redetermined. The inactivation timer mentioned here is the inactivation timer related to SPS PDSCH; wherein, the inactivation timer and the inactivation timer related to DCI can be the same or different. Each DRX cycle includes an activation period and an inactivation period. The sum of the activation period and the inactivation 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 window opening information, used to indicate the time and frequency position of sending window opening information; configuration information of window closing information Information, used to indicate the time and frequency position of sending window closing information; specify the opening time point of the receiving window as the receiving time point of the window opening information; specify the closing time point of the receiving window as the receiving time point of the window closing information.

In this example, the configuration information of the window opening information may include the time and frequency position at which the window opening information is sent, and the terminal device can monitor the window opening information at the sending time and frequency position. The configuration information of the window closing information may include the time and frequency position of sending the window closing information, etc., and the terminal device may monitor the window closing information at the sending time and frequency position. Among them, the window opening information and the window closing information are different information.

In another example, the second indication information includes: configuration information of the window control information; configuration information of the window control information, used to indicate the time and frequency position of sending the window control information; specifying the receiving window as the point between two adjacent window control information The time period between receiving time points; wherein, when the first window control information of two adjacent window control information is received, the specified receiving window is closed.

In this example, the configuration information of the window control information may include the time-frequency position of sending the window control information, etc., and the terminal device may monitor the window control information at the sending time-frequency position. Among them, it should be noted that if the window control information is received when the designated receiving window is closed, the designated receiving window is opened, that is, the receiving time point of the window control information is regarded as the opening time point of the designated receiving window. If the window control information is received when the designated receiving window is open, the designated receiving window is closed, that is, the receiving time point of the window control information is regarded as the closing time point of the designated receiving window.

Step S402: Receive the SPS PDSCH sent by the network device in the designated receiving window.

In the embodiment of the present application, the SPS PDSCH resources may be the first category of resources, that is, the terminal device may only monitor the PDSCH in each cycle of the SPS PDSCH resources within the designated reception window to receive the SPS PDSCH; while in the designated reception window Outside the window, stop monitoring PDSCH and stop receiving SPS PDSCH.

In the embodiment of this application, SPS PDSCH resources can be used to transmit XR services. Among them, the number of specified receiving windows can be one or more.

In the SPS PDSCH receiving method provided in the embodiment of this application, the terminal device can receive the second indication information sent by the network device. The second indication information is used to indicate the designated receiving window; receive the SPS PDSCH sent by the network device in the designated receiving window, Therefore, the terminal device only monitors the PDSCH in each cycle within the designated reception window, reducing the number of times the terminal device monitors the PDSCH and reducing the energy consumption of the terminal device. Another benefit is that by using a designated reception window to limit the reception of SPS PDSCH, network equipment does not need to frequently send DCI activation information and DCI deactivation information for each XR service cycle, which is beneficial to reducing network overhead.

Please refer to Figure 5. Figure 5 is a schematic flow chart of another SPS PDSCH receiving method provided by an embodiment of the present application.

In another example, the terminal device may receive the SPS PDSCH configuration information sent by the network device, and then may 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 can receive the SPS PDSCH configuration information sent by the network device, and then can receive the DCI activation information of the SPS PDSCH resource, and the terminal device can also receive the first indication information. The first indication information may carry the 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 DCI activation information, and may be information other than the SPS PDSCH configuration information and the DCI activation information.

Step S502: Receive second indication information sent by the network device, where the second indication information is used to indicate a designated receiving window.
