Description

一种PSFCH传输方法、装置、芯片及模组设备A PSFCH transmission method, device, chip and module equipment

技术领域Technical field

本发明涉及通信技术领域，尤其涉及一种PSFCH传输方法、装置、芯片及模组设备。The present invention relates to the field of communication technology, and in particular to a PSFCH transmission method, device, chip and module equipment.

背景技术Background technique

车联网(vehicle to everything，V2X)是智能交通运输***的关键技术，被认为是物联网体系中最有产业潜力、市场需求最明确的领域之一。车联网一般是指通过装载在车上的传感器、车载终端等提供车辆信息，实现车辆到车辆(vehicle to vehicle，V2V)，车辆到基础设施(vehicle to infrastructure，V2I)，车辆到网络(vehicle to network，V2N)以及车辆到行人(vehicle to pedestrian，V2P)之间的相互通信的通信网络。Vehicle to everything (V2X) is a key technology for intelligent transportation systems and is considered to be one of the areas with the greatest industrial potential and clearest market demand in the Internet of Things system. The Internet of Vehicles generally refers to providing vehicle information through sensors, vehicle-mounted terminals, etc. mounted on the vehicle, realizing vehicle to vehicle (V2V), vehicle to infrastructure (vehicle to infrastructure, V2I), and vehicle to network (vehicle to network). network (V2N) and vehicle to pedestrian (vehicle to pedestrian (V2P)) communication network.

在新无线(new radio，NR)V2X的场景中，发送终端采用一个子信道向接收终端发送物理侧行链路共享信道(physical sidelink shared channel，PSSCH)之后，接收终端要向发送终端进行混合自动重传请求(hybrid automatic repeatrequest，HARQ)反馈，HARQ反馈为肯定应答(acknowledgement，ACK)或否定应答(negativeacknowledgement，NACK)，ACK表示接收终端正确接收到PSSCH，NACK表示接收终端未正确接收到PSSCH。In the new radio (NR) V2X scenario, after the sending terminal uses a sub-channel to send the physical sidelink shared channel (PSSCH) to the receiving terminal, the receiving terminal needs to perform hybrid automatic transmission to the sending terminal. Retransmission request (hybrid automatic repeatrequest, HARQ) feedback, HARQ feedback is a positive response (acknowledgement, ACK) or a negative response (negative acknowledgment, NACK). ACK indicates that the receiving terminal correctly received the PSSCH, and NACK indicates that the receiving terminal did not receive the PSSCH correctly.

HARQ反馈承载在物理侧行链路反馈信道(physical sidelink feedback channel，PSFCH)上。目前Rel16标准中支持接收终端在一个时隙中同时传输PSFCH的数目为4个，8个或者16个。一个PSFCH的符号长度为2个符号。在一个时隙中的倒数第2个符号和倒数第3个符号用于映射PSFCH。HARQ feedback is carried on the physical sidelink feedback channel (PSFCH). Currently, the Rel16 standard supports the receiving terminal to transmit 4, 8 or 16 PSFCHs simultaneously in one time slot. The symbol length of a PSFCH is 2 symbols. The second to last symbol and the third to last symbol in a slot are used to map the PSFCH.

Rel 16标准中考虑的是FR1频段的场景，在发送PSFCH时不需要考虑PSSCH的发送波束(beam)。然而在Rel 18标准中考虑了FR2频段的场景，在发送PSFCH时需要考虑PSSCH的发送波束。在FR2频段的场景下一个接收终端不一定支持多个波束同时发送，例如，一个接收终端可能同时仅支持发送1个波束。在接收终端不支持多个波束同时发送时，如果在同一PSFCH时隙中需要同时使用多个波束发送PSFCH，终端设备将无法确定应该如何发送PSFCH，从而导致PSFCH发送失败。The Rel 16 standard considers the FR1 frequency band scenario, and the PSSCH transmission beam does not need to be considered when transmitting PSFCH. However, the Rel 18 standard considers the FR2 frequency band scenario, and the PSSCH transmission beam needs to be considered when transmitting PSFCH. In the FR2 frequency band scenario, a receiving terminal may not support simultaneous transmission of multiple beams. For example, a receiving terminal may only support transmitting one beam at a time. When the receiving terminal does not support simultaneous transmission of multiple beams, if multiple beams need to be used to transmit PSFCH simultaneously in the same PSFCH time slot, the terminal equipment will not be able to determine how to send PSFCH, resulting in PSFCH transmission failure.

第一方面，本申请提供一种PSFCH传输方法，应用于第一终端设备，该第一终端设备不支持多个波束同时发送，该方法包括：In the first aspect, this application provides a PSFCH transmission method, which is applied to a first terminal device. The first terminal device does not support multiple Beams are sent simultaneously. The method includes:

采用一个第一波束，发送物理侧链反馈信道(PSFCH)时隙中的PSFCH；其中，第一波束为PSFCH时隙中的优先级最高的PSFCH对应的波束，或者第一波束为在PSFCH时隙中对应最多PSFCH的波束，或者第一波束为波束配置信息为PSFCH时隙配置的一个波束，或者第一波束为PSFCH时隙关联的第一物理侧链共享信道(PSSCH)对应的波束，第一PSSCH为PSFCH时隙关联的至少一个PSSCH中传输时间最早的PSSCH。Use a first beam to transmit the PSFCH in the physical side chain feedback channel (PSFCH) time slot; where the first beam is the beam corresponding to the PSFCH with the highest priority in the PSFCH time slot, or the first beam is the beam in the PSFCH time slot The beam corresponding to the most PSFCHs in PSSCH is the PSSCH with the earliest transmission time among at least one PSSCH associated with the PSFCH time slot.

基于第一方面所描述的方法，第一终端设备在不支持多个波束同时发送时，会合理地确定一个第一波束来发送PSFCH时隙中的PSFCH，可以避免在同一PSFCH时隙中需要同时使用多个波束发送PSFCH，从而能够成功发送PSFCH。通过使第一波束为PSFCH时隙中的优先级最高的PSFCH对应的波束，能够保证优先级最高的PSFCH的传输性能。通过使第一波束为在PSFCH时隙中对应最多PSFCH的波束，能够保证较多PSFCH的传输性能。通过使第一波束为波束配置信息为PSFCH时隙配置的一个波束，能够使PSFCH时隙的波束被灵活地配置。通过使第一波束为PSFCH时隙关联的第一PSSCH对应的波束，能够使第一PSSCH关联的PSFCH的传输性能得到保证。Based on the method described in the first aspect, when the first terminal device does not support simultaneous transmission of multiple beams, it will reasonably determine a first beam to transmit the PSFCH in the PSFCH time slot, which can avoid the need for simultaneous transmission in the same PSFCH time slot. The PSFCH is transmitted using multiple beams, so that the PSFCH can be successfully transmitted. By making the first beam a beam corresponding to the PSFCH with the highest priority in the PSFCH time slot, the transmission performance of the PSFCH with the highest priority can be guaranteed. By making the first beam the beam corresponding to the most PSFCHs in the PSFCH time slot, the transmission performance of more PSFCHs can be ensured. By making the first beam be a beam configured by the beam configuration information for the PSFCH time slot, the beam of the PSFCH time slot can be flexibly configured. By making the first beam a beam corresponding to the first PSSCH associated with the PSFCH time slot, the transmission performance of the PSFCH associated with the first PSSCH can be guaranteed.

在一种可能的实现中，PSFCH时隙中具有多个优先级最高的PSFCH；第一波束为PSFCH时隙中的优先级最高的PSFCH对应的波束具体为：第一波束为多个优先级最高的PSFCH中的第一PSFCH对应的波束；在多个优先级最高的PSFCH中，第一PSFCH所关联的PSSCH的传输时间最早，或者，在多个优先级最高的PSFCH中，第一PSFCH的索引号最大或最小。In a possible implementation, there are multiple PSFCHs with the highest priority in the PSFCH time slot; the first beam is the PSFCH with the highest priority in the PSFCH time slot. Specifically, the beam corresponding to the PSFCH with the highest priority is: the first beam is multiple PSFCHs with the highest priority. The beam corresponding to the first PSFCH among the PSFCHs; among the multiple PSFCHs with the highest priority, the transmission time of the PSSCH associated with the first PSFCH is the earliest, or, among the multiple PSFCHs with the highest priority, the index of the first PSFCH The largest or smallest number.

如果使用第一波束来传输PSFCH时隙中除第一波束对应的PSFCH之外的PSFCH，PSFCH时隙中除第一波束对应的PSFCH之外的PSFCH的传输性能可能得不到保证。因此，采用第一波束，只需要发送PSFCH时隙中第一波束对应的PSFCH即可，这样能够节省传输资源。 If the first beam is used to transmit PSFCHs in the PSFCH time slot other than the PSFCH corresponding to the first beam, the transmission performance of the PSFCHs in the PSFCH time slot other than the PSFCH corresponding to the first beam may not be guaranteed. Therefore, using the first beam, only the PSFCH corresponding to the first beam in the PSFCH time slot needs to be transmitted, which can save transmission resources.

下面对本申请实施例涉及的PSFCH时隙进行介绍：The following is an introduction to the PSFCH time slots involved in the embodiments of this application:

PSFCH时隙为用于传输PSFCH的时隙，即PSFCH所在的时隙，在一个PSFCH时隙中可能存在多个被调度的PSFCH。一个PSFCH的符号长度为2个符号。在一个时隙中的倒数第2个符号和倒数第3个符号用于映射PSFCH。一个或多个时隙的PSSCH可以映射到同一个具有一个或多个PSFCH资源的时隙中，即一个PSFCH时隙可以关联一个或多个时隙的PSSCH。例如，如图2所示，PSSCH-1位于时隙1，PSSCH-2位于时隙2。PSFCH时隙中包括PSFCH-1和PSFCH-2。PSFCH-1与PSSCH-1关联，PSFCH-2与PSSCH-2关联，即PSFCH-1用于对PSSCH-1进行反馈，PSFCH-2用于对PSSCH-2进行反馈。那么PSSCH-1和PSSCH-2均与PSFCH时隙关联。同一PSFCH时隙中可包括一个或多个第二终端设备的PSFCH。The PSFCH time slot is a time slot used for transmitting PSFCH, that is, the time slot in which the PSFCH is located. There may be multiple scheduled PSFCHs in one PSFCH time slot. The symbol length of a PSFCH is 2 symbols. The second to last symbol and the third to last symbol in a slot are used to map the PSFCH. The PSSCH of one or more time slots can be mapped to the same time slot with one or more PSFCH resources, that is, one PSFCH time slot can be associated with the PSSCH of one or more time slots. For example, as shown in Figure 2, PSSCH-1 is located in time slot 1 and PSSCH-2 is located in time slot 2. The PSFCH time slot includes PSFCH-1 and PSFCH-2. PSFCH-1 is associated with PSSCH-1, and PSFCH-2 is associated with PSSCH-2, that is, PSFCH-1 is used to provide feedback to PSSCH-1, and PSFCH-2 is used to provide feedback to PSSCH-2. Then PSSCH-1 and PSSCH-2 are both associated with PSFCH slots. The same PSFCH time slot may include PSFCHs of one or more second terminal devices.

为了能够在接收终端不支持多个波束同时发送时，成功发送PSFCH，本申请提供了一种PSFCH传输方法、装置、芯片及模组设备。下面进一步对本申请实施例提供的PSFCH传输方法、装置、芯片及模组设备进行详细描述。In order to successfully transmit PSFCH when the receiving terminal does not support simultaneous transmission of multiple beams, this application provides a PSFCH transmission method, device, chip and module equipment. The PSFCH transmission method, device, chip and module equipment provided by the embodiments of the present application are further described in detail below.

The priority of the PSSCH may be indicated by the PSCCH that schedules the PSSCH. Among them, the lower the priority value, the higher the priority.

图3是本申请实施例提供的一种PSFCH传输方法的流程示意图。如图3所示，该PSFCH传输方法包括如下步骤301。图3所示的方法执行主体可以为第一终端设备。或者，图3所示的方法执行主体可以为第一终端设备中的芯片。Figure 3 is a schematic flowchart of a PSFCH transmission method provided by an embodiment of the present application. As shown in Figure 3, the PSFCH transmission method includes the following steps 301. The method execution subject shown in Figure 3 may be the first terminal device. Alternatively, the method execution subject shown in Figure 3 may be a chip in the first terminal device.

301、第一终端设备采用一个第一波束，发送PSFCH时隙中的PSFCH。301. The first terminal device uses a first beam to send the PSFCH in the PSFCH time slot.

在本申请实施例中，第一终端设备不支持多个波束同时发送。In this embodiment of the present application, the first terminal device does not support simultaneous transmission of multiple beams.

其中，第一波束可以是以下四种方式中的任意一种：Among them, the first beam can be in any of the following four ways:

方式一、第一波束为PSFCH时隙中的优先级最高的PSFCH对应的波束。 Method 1: The first beam is the beam corresponding to the PSFCH with the highest priority in the PSFCH time slot.

其中，PSFCH时隙中可以包括一个或多个PSFCH。PSFCH时隙中的一个PSFCH与一个波束对应，且PSFCH时隙中的一个PSFCH对应一个优先级。例如，PSFCH时隙中的PSFCH与波束和优先级之间的对应关系可如图4所示。如图4所示，每一行表示一个PSFCH与波束和优先级之间的对应关系。其中，PSFCH-1对应波束beam-2和优先级Priority-2。PSFCH-2对应波束beam-1和优先级Priority-1。PSFCH-3对应波束beam-2和优先级Priority-3。PSFCH-4对应波束beam-1和优先级Priority-4。如图4所示，由于PSFCH-2对应的优先级最高，因此第一波束为波束beam-1。The PSFCH time slot may include one or more PSFCHs. One PSFCH in the PSFCH time slot corresponds to one beam, and one PSFCH in the PSFCH time slot corresponds to one priority. For example, the corresponding relationship between the PSFCH, the beam and the priority in the PSFCH time slot can be shown in Figure 4. As shown in Figure 4, each row represents the corresponding relationship between a PSFCH, beam and priority. Among them, PSFCH-1 corresponds to beam-2 and priority Priority-2. PSFCH-2 corresponds to beam-1 and priority Priority-1. PSFCH-3 corresponds to beam-2 and priority-3. PSFCH-4 corresponds to beam-1 and priority Priority-4. As shown in Figure 4, since PSFCH-2 has the highest priority, the first beam is beam beam-1.

在一种可能的实现中，PSFCH时隙中具有多个优先级最高的PSFCH；第一波束为PSFCH时隙中的优先级最高的PSFCH对应的波束具体为：第一波束为多个优先级最高的PSFCH中的第一PSFCH对应的波束；在多个优先级最高的PSFCH中，第一PSFCH所关联的PSSCH的传输时间最早。可选的，如果仍然有多个PSFCH所关联的PSSCH的传输时间相同，那么终端设备可以在所述多个PSFCH中任意选择一个作为第一PSFCH；或者，在多个优先级最高的PSFCH中，第一PSFCH的频域资源索引号最大或最小。可选的，如果仍然有多个PSFCH的频域资源相同，那么终端设备可以在所述多个PSFCH中任意选择一个作为第一PSFCH。基于该可能的实现方式，在PSFCH时隙中具有多个优先级最高的PSFCH时，能够合理地确定一个波束。In a possible implementation, there are multiple PSFCHs with the highest priority in the PSFCH time slot; the first beam is the PSFCH with the highest priority in the PSFCH time slot. Specifically, the beam corresponding to the PSFCH with the highest priority is: the first beam is multiple PSFCHs with the highest priority. The beam corresponding to the first PSFCH among the PSFCHs; among the multiple PSFCHs with the highest priority, the transmission time of the PSSCH associated with the first PSFCH is the earliest. Optionally, if there are still multiple PSFCHs associated with the same PSSCH transmission time, the terminal device can arbitrarily select one of the multiple PSFCHs as the first PSFCH; or, among the multiple PSFCHs with the highest priority, The frequency domain resource index number of the first PSFCH is the largest or the smallest. Optionally, if there are still multiple PSFCHs with the same frequency domain resources, the terminal device can arbitrarily select one of the multiple PSFCHs as the first PSFCH. Based on this possible implementation, when there are multiple PSFCHs with the highest priority in the PSFCH time slot, one beam can be reasonably determined.

例如，以在多个优先级最高的PSFCH中，第一PSFCH所关联的PSSCH的传输时间最早为例。如图5所示，PSFCH时隙中的PSFCH-1和PSFCH-2的优先级最高。如图6所示，PSFCH-1关联的PSSCH-1的传输时间比PSFCH-2关联的PSSCH-2的传输时间早，因此，第一PSFCH为PSFCH-1，第一波束为PSFCH-1对应的波束，即波束beam-2。For example, among multiple PSFCHs with the highest priority, the transmission time of the PSSCH associated with the first PSFCH is the earliest. As shown in Figure 5, PSFCH-1 and PSFCH-2 in the PSFCH time slot have the highest priority. As shown in Figure 6, the transmission time of PSSCH-1 associated with PSFCH-1 is earlier than the transmission time of PSSCH-2 associated with PSFCH-2. Therefore, the first PSFCH is PSFCH-1 and the first beam is corresponding to PSFCH-1. The beam is beam-2.

再如，在多个优先级最高的PSFCH中，第一PSFCH的索引号最小为例。如图5所示，PSFCH时隙中的PSFCH-1和PSFCH-2的优先级最高。由于PSFCH-1的索引号小于PSFCH-2的索引号，所以第一PSFCH为PSFCH-1，第一波束为PSFCH-1对应的波束，即波束beam-2。For another example, among multiple PSFCHs with the highest priority, the first PSFCH has the smallest index number. As shown in Figure 5, PSFCH-1 and PSFCH-2 in the PSFCH time slot have the highest priority. Since the index number of PSFCH-1 is smaller than the index number of PSFCH-2, the first PSFCH is PSFCH-1, and the first beam is the beam corresponding to PSFCH-1, that is, beam beam-2.

再如，在多个优先级最高的PSFCH中，第一PSFCH的索引号最大为例。如图5所示，PSFCH时隙中的PSFCH-1和PSFCH-2的优先级最高。由于PSFCH-1的索引号小于PSFCH-2的索引号，所以第一PSFCH为PSFCH-2，第一波束为PSFCH-2对应的波束，即波束beam-1。For another example, among multiple PSFCHs with the highest priority, the index number of the first PSFCH is the largest. As shown in Figure 5, PSFCH-1 and PSFCH-2 in the PSFCH time slot have the highest priority. Since the index number of PSFCH-1 is smaller than the index number of PSFCH-2, the first PSFCH is PSFCH-2, and the first beam is the beam corresponding to PSFCH-2, that is, beam beam-1.

方式二、第一波束为在PSFCH时隙中对应最多PSFCH的波束。Method 2: The first beam is the beam corresponding to the most PSFCHs in the PSFCH time slot.

其中，PSFCH时隙中可以包括一个或多个PSFCH。PSFCH时隙中的一个PSFCH与一个波束对应，且PSFCH时隙中的一个PSFCH对应一个优先级。例如，PSFCH时隙中的PSFCH与波束和优先级之间的对应关系可如图7所示。如图7所示，由于波束beam-1对应3个PSFCH，波束beam-2对应2个PSFCH。波束beam-1对应的PSFCH的数量大于波束beam-2对应的PSFCH的数量，因此，第一波束为波束beam-1。 The PSFCH time slot may include one or more PSFCHs. One PSFCH in the PSFCH time slot corresponds to one beam, and one PSFCH in the PSFCH time slot corresponds to one priority. For example, the corresponding relationship between the PSFCH, the beam and the priority in the PSFCH time slot can be shown in Figure 7. As shown in Figure 7, since beam beam-1 corresponds to 3 PSFCHs, beam beam-2 corresponds to 2 PSFCHs. The number of PSFCHs corresponding to beam beam-1 is greater than the number of PSFCHs corresponding to beam beam-2. Therefore, the first beam is beam beam-1.

在一种可能的实现中，在PSFCH时隙中具有多个第二波束对应最多PSFCH；第一波束为在PSFCH时隙中对应最多PSFCH的波束具体为：第一波束为多个第二波束中优先级最高的PSFCH对应的波束。可选的，如果仍然存在多个优先级相同的第二波束，那么终端设备任意选择所述第二波束中的一个波束作为第一波束。基于该可能的实现方式，在PSFCH时隙中具有多个第二波束对应最多PSFCH时，能够保证优先级最高的PSFCH的传输性能。In a possible implementation, there are multiple second beams in the PSFCH time slot corresponding to the most PSFCHs; the first beam is the beam corresponding to the most PSFCHs in the PSFCH time slot. Specifically: the first beam is one of the multiple second beams. The beam corresponding to the PSFCH with the highest priority. Optionally, if there are still multiple second beams with the same priority, the terminal device arbitrarily selects one of the second beams as the first beam. Based on this possible implementation, when there are multiple second beams corresponding to the most PSFCHs in the PSFCH time slot, the transmission performance of the PSFCH with the highest priority can be guaranteed.

例如，如图8所示，由于波束beam-1和波束beam-2对应的PSFCH的数量相同，即都是对应最多PSFCH的波束。那么需要基于PSFCH的优先级从波束beam-1和波束beam-2中选择一个作为第一波束。由于波束beam-1对应的PSFCH-2的优先级最高。因此，第一波束为波束beam-1。For example, as shown in Figure 8, since the number of PSFCHs corresponding to beam beam-1 and beam-2 is the same, that is, they are both beams corresponding to the most PSFCHs. Then one needs to be selected from beam beam-1 and beam beam-2 as the first beam based on the priority of the PSFCH. Because beam beam-1 corresponds to PSFCH-2, which has the highest priority. Therefore, the first beam is beam-1.

在方式一或方式二下，在一种可能的实现中，第一终端设备采用第一波束，发送PSFCH时隙中的PSFCH，包括：第一终端设备采用第一波束，发送PSFCH时隙中第一波束对应的PSFCH。In mode one or mode two, in a possible implementation, the first terminal device uses the first beam to send the PSFCH in the PSFCH time slot, including: the first terminal device uses the first beam to send the PSFCH in the PSFCH time slot. PSFCH corresponding to one beam.

例如，如图4所示，假设第一波束为波束beam-1，则第一终端设备采用波束beam-1，在PSFCH时隙中，发送PSFCH-2和/或PSFCH-4。无需发送PSFCH-1和PSFCH-3。For example, as shown in Figure 4, assuming that the first beam is beam beam-1, the first terminal device uses beam beam-1 to send PSFCH-2 and/or PSFCH-4 in the PSFCH time slot. There is no need to send PSFCH-1 and PSFCH-3.

如果使用第一波束来传输PSFCH时隙中除第一波束对应的PSFCH之外的PSFCH，PSFCH时隙中除第一波束对应的PSFCH之外的PSFCH的传输性能可能得不到保证。因此，采用第一波束，只需要发送PSFCH时隙中第一波束对应的PSFCH即可，这样能够节省传输资源。If the first beam is used to transmit PSFCHs in the PSFCH time slot other than the PSFCH corresponding to the first beam, the transmission performance of the PSFCHs in the PSFCH time slot other than the PSFCH corresponding to the first beam may not be guaranteed. Therefore, using the first beam, only the PSFCH corresponding to the first beam in the PSFCH time slot needs to be transmitted, which can save transmission resources.

在方式一或方式二下，可选的，第一终端设备还可将PSFCH时隙内第一波束对应的PSFCH的数量作为数量N_sch,Tx,PSFCH，并基于数量N_sch,Tx,PSFCH从PSFCH时隙内第一波束对应的PSFCH中确定N_Tx,PSFCH个PSFCH；第一终端设备采用第一波束，发送PSFCH时隙中第一波束对应的PSFCH，包括：第一终端设备采用第一波束，发送该N_Tx,PSFCH个PSFCH。In mode one or mode two, optionally, the first terminal equipment can also use the number of PSFCHs corresponding to the first beam in the PSFCH time slot as the number N _sch,Tx,PSFCH , and based on the number N _{sch,Tx,PSFCH,} Determine N _{Tx,PSFCH PSFCHs in the PSFCH} corresponding to the first beam in the PSFCH time slot; the first terminal equipment uses the first beam to send the PSFCH corresponding to the first beam in the PSFCH time slot, including: the first terminal equipment uses the first beam , sending the N _Tx,PSFCH PSFCHs.

在该可能的实现中，第一终端设备将PSFCH时隙内第一波束对应的PSFCH的数量记为数量N_sch,Tx,PSFCH，以便后续基于N_sch,Tx,PSFCH进行功率控制。也就是说，第一终端设备需要进行功率控制，不一定会发送PSFCH时隙内第一波束对应的所有PSFCH。这样有利于保证第一终端设备发送PSFCH的功率在第一终端设备所支持的发送功率之内。In this possible implementation, the first terminal equipment records the number of PSFCHs corresponding to the first beam in the PSFCH time slot as the number N _sch,Tx,PSFCH , so that subsequent power control is performed based on N _sch,Tx,PSFCH . In other words, the first terminal equipment needs to perform power control and may not necessarily transmit all PSFCHs corresponding to the first beam in the PSFCH time slot. This is beneficial to ensuring that the power used by the first terminal equipment to send the PSFCH is within the transmission power supported by the first terminal equipment.

例如，如图4所示，假设第一波束为波束beam-1，由于波束beam-1对应PSFCH-2和PSFCH-4。因此，PSFCH时隙内波束beam-1对应的PSFCH的数量为2，即N_sch,Tx,PSFCH为2。For example, as shown in Figure 4, assume that the first beam is beam beam-1, because beam beam-1 corresponds to PSFCH-2 and PSFCH-4. Therefore, the number of PSFCHs corresponding to beam-1 in the PSFCH time slot is 2, that is, N _{sch, Tx, PSFCH} is 2.

例如，第一终端设备进行功率控制的具体实施方式如下：For example, the specific implementation of power control by the first terminal device is as follows:

当高层参数dl-P0-PSFCH提供时，一个PSFCH的发射功率为:
P_PSFCH,one＝P_O,PSFCH+10log₁₀(2^μ)+α_PSFCH·PL[dBm]。When the higher layer parameter dl-P0-PSFCH is provided, the transmit power of a PSFCH is:
P _PSFCH,one = P _O,PSFCH +10log ₁₀ (2 ^μ ) + α _PSFCH ·PL [dBm].

其中，P_PSFCH,one表示一个PSFCH的发射功率。P_O,PSFCH为高层参数dl-P0-PSFCH。α_PSFCH为路径损耗参数的调整因子，PL为路径损耗参数。Among them, _PPSFCH,one represents the transmit power of one PSFCH.

P_PSFCH,k(i)＝P_PSFCH,one[dBm]。 P _PSFCH,k (i)=P _PSFCH,one [dBm].

其中，N_max,PSFCH为第一终端设备最大能够发送的PSFCH的数量。P_CMAX为第一终端设备发送PSFCH的最大总功率。N_Tx,PSFCH为第一终端设备实际发送的PSFCH的数量。P_PSFCH,k(i)为第一终端设备在第i个PSFCH传输机会(transmission occasion)发送的第k个PSFCH的发送功率。后文相同参数的含义相同，后文不再赘述。Among them, N _max,PSFCH is the maximum number of PSFCHs that the first terminal device can send. _PCMAX is the maximum total power of the first terminal equipment to send PSFCH. N _Tx,PSFCH is the number of PSFCH actually sent by the first terminal equipment. P _PSFCH,k (i) is the transmission power of the k-th PSFCH sent by the first terminal equipment at the i-th PSFCH transmission opportunity (transmission occasion). The same parameters below have the same meaning and will not be described again.

情况2：Case 2:

当高层参数dl-P0-PSFCH提供时，如果N_sch,Tx,PSFCH≤N_max,PSFCH,同时不满足P_PSFCH,one+10log₁₀(N_sch,Tx,PSFCH)≤P_CMAX，那么第一终端设备自主从N_sch,Tx,PSFCH个PSFCH中选择N_Tx,PSFCH个PSFCH，按照PSFCH优先级升序的次序，需要满足其中：When the high-level parameter dl-P0-PSFCH is provided, if N _sch,Tx,PSFCH ≤N _{max,PSFCH and P PSFCH} _,one +10log ₁₀ (N _sch,Tx,PSFCH ) ≤ P _CMAX is not satisfied at the same time, then the first terminal The device autonomously selects N _Tx, _{PSFCH PSFCHs from N sch, Tx,} PSFCH PSFCHs, in ascending order of PSFCH priority, and needs to meet in:

同时，PSFCH的功率如下：At the same time, the power of PSFCH is as follows:

P_PSFCH,k(i)＝min(P_CMAX-10log₁₀(N_Tx,PSFCH),P_PSFCH,one)[dBm]。P _{PSFCH, k} (i) = min (P _CMAX -10 log ₁₀ (N _{Tx, PSFCH} ), P _{PSFCH, one} ) [dBm].

情况3：Case 3:

当高层参数dl-P0-PSFCH提供时，如果N_sch,Tx,PSFCH>N_max,PSFCH,那么第一终端设备自主从N_sch,Tx,PSFCH个PSFCH中选择N_max,PSFCH个PSFCH，按照PSFCH优先级升序的次序。如果满足P_PSFCH,one+10log₁₀(N_sch,Tx,PSFCH)≤P_CMAX，那么：When the higher layer parameter dl-P0-PSFCH is provided, if N _sch,Tx,PSFCH >N _max,PSFCH , then the first terminal equipment autonomously selects N _max, PSFCH PSFCHs from N _sch,Tx,PSFCH PSFCHs, according to the PSFCH Order in ascending priority order. If P _PSFCH,one +10log ₁₀ (N _sch,Tx,PSFCH )≤P _CMAX is satisfied, then:

If P _PSFCH,one +10log ₁₀ (N _sch,Tx,PSFCH )≤P _CMAX is not satisfied, then the first terminal equipment independently selects from N _max,PSFCH PSFCHs.

P_PSFCH,k(i)＝P_CMAX-10log₁₀(N_Tx,PSFCH)[dBm]。P _{PSFCH, k} (i) = P _CMAX -10 log ₁₀ (N _{Tx, PSFCH} ) [dBm].

其中，N_Tx,PSFCH是按照PSFCH优先级升序从N_sch,Tx,PSFCH个PSFCH中选择出的。Among them, N _{Tx, PSFCH} are selected from N _{sch, Tx, PSFCH} PSFCH in ascending order of PSFCH priority.

方式三、第一波束为波束配置信息为PSFCH时隙配置的一个波束。Method 3: The first beam is a beam whose beam configuration information is configured for the PSFCH time slot.

在方式三中，可以理解为PSFCH时隙中的PSFCH与波束预先没有建立对应关系。但可以通过波束配置信息为整个PSFCH时隙配置一个波束。其中，所述波束可以用于对应PSFCH时隙内每一个PSFCH的发送。第一终端设备可以使用波束配置信息为PSFCH时隙配置的波束来传输这个PSFCH时隙内的PSFCH。In the third method, it can be understood that there is no corresponding relationship between the PSFCH and the beam in the PSFCH time slot in advance. However, a beam can be configured for the entire PSFCH slot through beam configuration information. Wherein, the beam may be used for transmission corresponding to each PSFCH in the PSFCH time slot. The first terminal device may transmit the PSFCH in the PSFCH time slot using the beam configured by the beam configuration information for the PSFCH time slot.

在一种可能的实现中，第一终端设备可接收接入网设备通过高层信令或者DCI或者MAC-CE发送的波束配置信息。相应地，接入网设备也可通过高层信令或者DCI或者MAC-CE向第一终端设备发送该波束配置信息。基于该可能的实现方式，能够灵活地为PSFCH时隙配置波束。In a possible implementation, the first terminal device may receive beam configuration information sent by the access network device through high-layer signaling or DCI or MAC-CE. Correspondingly, the access network device may also send the beam configuration information to the first terminal device through high-layer signaling or DCI or MAC-CE. Based on this possible implementation, beams can be flexibly configured for PSFCH time slots.

在一种可能的实现中，第一终端设备可接收第二终端设备通过高层信令或者SCI或者MAC-CE发送的波束配置信息。相应地，第二终端设备可通过高层信令或者SCI或者MAC-CE向第一终端设备发送波束配置信息。可选的，接入网设备可先将波束配置信息发送给第二终端设备，第二终端设备接收波束配置信息之后，再将该波束配置信息转发给第一终端设备。基于该可能的实现方式，能够灵活地为PSFCH时隙配置波束。In a possible implementation, the first terminal device may receive the beam configuration information sent by the second terminal device through high-layer signaling or SCI or MAC-CE. Correspondingly, the second terminal device may send the beam configuration information to the first terminal device through high-layer signaling or SCI or MAC-CE. Optionally, the access network device may first send the beam configuration information to the second terminal device, and after receiving the beam configuration information, the second terminal device forwards the beam configuration information to the first terminal device. Based on this possible implementation, beams can be flexibly configured for PSFCH time slots.

在一种可能的实现中，第一终端设备还可将PSFCH时隙中的PSFCH的数量作为数量N_sch,Tx,PSFCH；基于该数量N_sch,Tx,PSFCH从该PSFCH时隙中的PSFCH中确定N_Tx,PSFCH个PSFCH；第一终端设备采用第一波束，发送PSFCH时隙中的PSFCH，包括：第一终端设备采用第一波束，发送该N_Tx,PSFCH个PSFCH。In a possible implementation, the first terminal equipment may also use the number of PSFCHs in the PSFCH time slot as the number N _sch,Tx,PSFCH ; based on the number N _{sch,Tx,PSFCH, it is obtained} from the PSFCH in the PSFCH time slot. Determining N _Tx,PSFCH PSFCHs; the first terminal equipment uses the first beam to send the PSFCH in the PSFCH time slot, including: the first terminal equipment uses the first beam to send the N _Tx,PSFCH PSFCHs.

在该可能的实现中，第一终端设备将PSFCH时隙中的PSFCH的数量记为数量N_sch,Tx,PSFCH，以便后续基于N_sch,Tx,PSFCH进行功率控制。也就是说，第一终端设备需要进行功率控制，不一定会发送PSFCH时隙内的所有PSFCH。这样有利于保证第一终端设备发送PSFCH的功率在第一终端设备所支持的发送功率之内。In this possible implementation, the first terminal equipment records the number of PSFCHs in the PSFCH time slot as the number N _sch,Tx,PSFCH so that subsequent power control is performed based on N _sch,Tx,PSFCH . That is to say, the first terminal equipment needs to perform power control and may not necessarily transmit all PSFCHs in the PSFCH time slot. This is helpful to ensure that the power of the first terminal device to send PSFCH is within the transmission power supported by the first terminal device. within power.

例如，假设PSFCH时隙中一共具有4个PSFCH，则N_sch,Tx,PSFCH为4。For example, assuming that there are a total of 4 PSFCHs in the PSFCH time slot, N _{sch, Tx, PSFCH} is 4.

第一终端设备进行功率控制的具体实施方式可参见前文的描述，在此不赘述。For specific implementation methods of power control performed by the first terminal device, reference may be made to the foregoing description and will not be described in detail here.

方式四、第一波束为PSFCH时隙关联的第一PSSCH对应的波束，该第一PSSCH为PSFCH时隙关联的至少一个PSSCH中传输时间最早的PSSCH。Method 4: The first beam is the beam corresponding to the first PSSCH associated with the PSFCH time slot, and the first PSSCH is the PSSCH with the earliest transmission time among at least one PSSCH associated with the PSFCH time slot.

在方式四中，可以理解为PSFCH时隙中的PSFCH与波束预先没有建立对应关系。第一终端设备可以从PSFCH时隙关联的PSSCH对应的波束中选择一个波束来传输这个PSFCH时隙内的PSFCH。在方式四中，第一终端设备从PSFCH时隙关联的PSSCH对应的波束中，选择第一PSSCH对应的波束来传输这个PSFCH时隙内的PSFCH，该第一PSSCH为PSFCH时隙关联的至少一个PSSCH中传输时间最早的PSSCH。可选的，如果存在多个关联不同波束的PSFCH关联的PSSCH的传输时间相同且最早，那么可以由终端设备任意选择一个PSFCH的波束作为第一波束。In the fourth method, it can be understood that there is no corresponding relationship established in advance between the PSFCH and the beam in the PSFCH time slot. The first terminal equipment may select a beam from the beam corresponding to the PSSCH associated with the PSFCH time slot to transmit the PSFCH in this PSFCH time slot. In the fourth method, the first terminal equipment selects the beam corresponding to the first PSSCH from the beam corresponding to the PSSCH associated with the PSFCH time slot to transmit the PSFCH in this PSFCH time slot. The first PSSCH is at least one of the PSFCH time slot associated beams. The PSSCH with the earliest transmission time among the PSSCHs. Optionally, if there are multiple PSFCHs associated with different beams and the transmission time of the PSSCH associated with them is the same and earliest, then the terminal device can arbitrarily select a PSFCH beam as the first beam.

举例来说，如图9所示，PSFCH时隙中包括PSFCH-1～PSFCH-4。该PSFCH时隙关联PSSCH-1～PSSCH-4。其中，PSSCH-1和PSSCH-2对应的波束为波束beam-1，PSSCH-3和PSSCH-4对应的波束为波束beam-2。由于PSSCH-1为PSFCH时隙关联的PSSCH中最早传输的PSSCH。所以第一波束为PSSCH-1对应的波束，第一终端设备使用PSSCH-1对应的波束beam-1来传输这个PSFCH时隙内的PSFCH。For example, as shown in Figure 9, the PSFCH time slot includes PSFCH-1 to PSFCH-4. This PSFCH time slot is associated with PSSCH-1~PSSCH-4. Among them, the beam corresponding to PSSCH-1 and PSSCH-2 is beam beam-1, and the beam corresponding to PSSCH-3 and PSSCH-4 is beam beam-2. Because PSSCH-1 is the earliest transmitted PSSCH among the PSSCHs associated with the PSFCH time slot. Therefore, the first beam is the beam corresponding to PSSCH-1, and the first terminal equipment uses the beam beam-1 corresponding to PSSCH-1 to transmit the PSFCH in this PSFCH time slot.

在一种可能的实现中，第一终端设备采用第一波束，发送PSFCH时隙中的PSFCH，包括：第一终端设备采用第一波束，发送第二PSSCH所关联的PSFCH，该第二PSSCH为PSFCH时隙关联的PSSCH中与第一波束对应的PSSCH。在该可能的实现中，采用第一波束，无需发送PSFCH时隙中的所有PSFCH，这样能够节省传输资源。In a possible implementation, the first terminal device uses the first beam to send the PSFCH in the PSFCH time slot, including: the first terminal device uses the first beam to send the PSFCH associated with the second PSSCH, and the second PSSCH is The PSSCH corresponding to the first beam among the PSSCHs associated with the PSFCH time slot. In this possible implementation, the first beam is used, and there is no need to send all PSFCHs in the PSFCH timeslot, which can save transmission resources.

例如，如图9所示，由于第一波束为波束beam-1，PSSCH-1和PSSCH-2都与波束beam-1对应。所以PSSCH-1和PSSCH-2都为第二PSSCH。PSSCH-1关联的PSFCH-1，PSSCH-2关联的PSFCH-2。第一终端设备采用波束beam-1发送PSFCH-1和/或PSFCH-2。For example, as shown in Figure 9, since the first beam is beam beam-1, both PSSCH-1 and PSSCH-2 correspond to beam beam-1. Therefore, both PSSCH-1 and PSSCH-2 are the second PSSCH. PSSCH-1 is associated with PSFCH-1, and PSSCH-2 is associated with PSFCH-2. The first terminal equipment uses beam beam-1 to send PSFCH-1 and/or PSFCH-2.

可选的，第一终端设备还可将PSFCH时隙内第二PSSCH所关联的PSFCH的数量作为数量N_sch,Tx,PSFCH，并基于数量N_sch,Tx,PSFCH从该PSFCH时隙内第二PSSCH所关联的PSFCH中确定N_Tx,PSFCH个PSFCH；第一终端设备采用第一波束，发送第二PSSCH所关联的PSFCH，包括：第一终端设备采用第一波束，发送该N_Tx,PSFCH个PSFCH。Optionally, the first terminal equipment may also use the number of PSFCHs associated with the second PSSCH in the PSFCH time slot as the number N _sch,Tx,PSFCH , and based on the number N _{sch,Tx,PSFCH,} select the second PSFCH in the PSFCH time slot. Determine N _Tx,PSFCH PSFCHs in the PSFCH associated with the PSSCH; the first terminal equipment uses the first beam to send the PSFCH associated with the second PSSCH, including: the first terminal equipment uses the first beam to send the N _Tx,PSFCH PSFCH.

在该可能的实现中，第一终端设备将第二PSSCH所关联的PSFCH的数量记为数量N_sch,Tx,PSFCH，以便后续基于N_sch,Tx,PSFCH进行功率控制。也就是说，第一终端设备需要进行功率控制，不一定会发送所有第二PSSCH所关联的PSFCH。这样有利于保证第一终端设备发送PSFCH的功率在第一终端设备所支持的发送功率之内。In this possible implementation, the first terminal equipment records the number of PSFCHs associated with the second PSSCH as the number N _sch,Tx,PSFCH , so that subsequent power control is performed based on N _sch,Tx,PSFCH . In other words, the first terminal device needs to perform power control and may not necessarily send all There is a PSFCH associated with the second PSSCH. This is beneficial to ensuring that the power used by the first terminal equipment to send the PSFCH is within the transmission power supported by the first terminal equipment.

例如，如图9所示，由于第一波束为波束beam-1，PSSCH-1和PSSCH-2都与波束beam-1对应。所以PSSCH-1和PSSCH-2都为第二PSSCH。PSSCH-1关联的PSFCH-1，PSSCH-2关联的PSFCH-2。因此，PSFCH时隙内第二PSSCH所关联的PSFCH的数量为2，即N_sch,Tx,PSFCH为2。For example, as shown in Figure 9, since the first beam is beam beam-1, both PSSCH-1 and PSSCH-2 correspond to beam beam-1. Therefore, both PSSCH-1 and PSSCH-2 are the second PSSCH. PSSCH-1 is associated with PSFCH-1, and PSSCH-2 is associated with PSFCH-2. Therefore, the number of PSFCHs associated with the second PSSCH in the PSFCH time slot is 2, that is, N _{sch, Tx, PSFCH} is 2.

在另一种可能的实现中，第一终端设备还可将PSFCH时隙中的PSFCH的数量作为数量N_sch,Tx,PSFCH，并基于数量N_sch,Tx,PSFCH从PSFCH时隙中的PSFCH中确定N_Tx,PSFCH个PSFCH；第一终端设备采用第一波束，发送PSFCH时隙中的PSFCH，包括：第一终端设备采用第一波束，发送该N_Tx,PSFCH个PSFCH。In another possible implementation, the first terminal device may also use the number of PSFCHs in the PSFCH time slot as the number N _sch,Tx,PSFCH , and extract the number of PSFCHs in the PSFCH time slot from the number N sch, _{Tx,PSFCH based on the number N sch,Tx,PSFCH} Determining N _Tx,PSFCH PSFCHs; the first terminal equipment uses the first beam to send the PSFCH in the PSFCH time slot, including: the first terminal equipment uses the first beam to send the N _Tx,PSFCH PSFCHs.

在该可能的实现中，第一终端设备将PSFCH时隙中的PSFCH的数量记为数量N_sch,Tx,PSFCH，以便后续基于N_sch,Tx,PSFCH进行功率控制。也就是说，第一终端设备需要进行功率控制，不一定会发送PSFCH时隙内的所有PSFCH。这样有利于保证第一终端设备发送PSFCH的功率在第一终端设备所支持的发送功率之内。In this possible implementation, the first terminal equipment records the number of PSFCHs in the PSFCH time slot as the number N _sch,Tx,PSFCH so that subsequent power control is performed based on N _sch,Tx,PSFCH . That is to say, the first terminal equipment needs to perform power control and may not necessarily transmit all PSFCHs in the PSFCH time slot. This is beneficial to ensuring that the power used by the first terminal equipment to send the PSFCH is within the transmission power supported by the first terminal equipment.

需要说明的是，本申请实施例中，采用第一波束，可以向一个或多个第二终端设备发送PSFCH时隙内的PSFCH。相应地，一个或多个第二终端设备可以接收PSFCH时隙中的PSFCH。例如，需要发送的PSFCH时隙内的PSFCH为PSFCH-1和PSFCH-2。如果PSFCH-1和PSFCH-2都是对第二终端设备1发送的PSSCH的反馈，则采用第一波束，1发送PSFCH-1和PSFCH-2。如果PSFCH-1对第二终端设备1发送的PSSCH的反馈，PSFCH-2对第二终端设备2发送的PSSCH的反馈，则采用第一波束，1发送PSFCH-1，并采用第一波束，2发送PSFCH-2。It should be noted that in this embodiment of the present application, the first beam may be used to transmit the PSFCH in the PSFCH time slot to one or more second terminal devices. Accordingly, one or more second terminal devices may receive the PSFCH in the PSFCH time slot. For example, the PSFCHs in the PSFCH timeslot that need to be sent are PSFCH-1 and PSFCH-2. If both PSFCH-1 and PSFCH-2 are feedback to the PSSCH sent by the second terminal equipment 1, then the first beam 1 is used to send PSFCH-1 and PSFCH-2. If PSFCH-1 provides feedback to the PSSCH sent by the second terminal equipment 1, and PSFCH-2 provides feedback to the PSSCH sent by the second terminal equipment 2, the first beam, 1, is used to transmit PSFCH-1, and the first beam, 2 is used. Send PSFCH-2.

基于图3所描述的方法，第一终端设备在不支持多个波束同时发送时，会合理地确定一个第一波束来发送PSFCH时隙中的PSFCH，从而成功发送PSFCH。通过使第一波束为PSFCH时隙中的优先级最高的PSFCH对应的波束，能够保证优先级最高的PSFCH的传输性能。通过使第一波束为在PSFCH时隙中对应最多PSFCH的波束，能够保证较多PSFCH的传输性能。通过使第一波束为波束配置信息为PSFCH时隙配置的一个波束，能够使PSFCH时隙的波束被灵活地配置。通过使第一波束为PSFCH时隙关联的第一PSSCH对应的波束，能够使第一PSSCH关联的PSFCH的传输性能得到保证。 Based on the method described in Figure 3, when the first terminal device does not support simultaneous transmission of multiple beams, it will reasonably determine a first beam to transmit the PSFCH in the PSFCH time slot, thereby successfully transmitting the PSFCH. By making the first beam a beam corresponding to the PSFCH with the highest priority in the PSFCH time slot, the transmission performance of the PSFCH with the highest priority can be guaranteed. By making the first beam the beam corresponding to the most PSFCHs in the PSFCH time slot, the transmission performance of more PSFCHs can be ensured. By making the first beam be a beam configured by the beam configuration information for the PSFCH time slot, the beam of the PSFCH time slot can be flexibly configured. By making the first beam a beam corresponding to the first PSSCH associated with the PSFCH time slot, the transmission performance of the PSFCH associated with the first PSSCH can be guaranteed.
