Description

由用户设备执行的方法以及用户设备Method performed by user equipment and user equipment 技术领域Technical Field
本发明涉及一种由用户设备执行的方法以及用户设备。The present invention relates to a method executed by a user equipment and the user equipment.
背景技术Background technique
在无线通信系统中，不同的通信节点之间可以进行信息交换。无线通信可以在授权频谱(licensed spectrum)和/或非授权频谱(unlicensed spectrum)上进行。无线通信系统的一个例子是由3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)标准化的系统，例如基于LTE(Long-Term Evolution)无线接入技术的系统，又如基于NR(New Radio)无线接入技术的系统。在一个基于3GPP规范的通信系统中，通信节点的例子可以包括UE(User Equipment，用户设备)和基站(例如eNB，又如gNB)。从基站到UE的无线链路(radio link)可以称为下行链路(DL，downlink)，从UE到基站的无线链路可以称为上行链路(UL，uplink)，UE之间的无线链路可以称为侧行链路(SL，sidelink)。基站和UE之间进行无线传输和/或接收的接口可以称为Uu接口(例如基于NR的NR-Uu接口；又如基于LTE的LTE-Uu接口)。UE之间进行无线传输和/或接收的接口可以称为PC5接口。In a wireless communication system, information can be exchanged between different communication nodes. Wireless communication can be performed on a licensed spectrum and/or an unlicensed spectrum. An example of a wireless communication system is a system standardized by 3GPP (3rd Generation Partnership Project), such as a system based on LTE (Long-Term Evolution) wireless access technology, and a system based on NR (New Radio) wireless access technology. In a communication system based on 3GPP specifications, examples of communication nodes may include UE (User Equipment) and base stations (such as eNBs, also known as gNBs). The radio link (radio link) from the base station to the UE may be called a downlink (DL), the radio link from the UE to the base station may be called an uplink (UL), and the radio link between UEs may be called a sidelink (SL). The interface for wireless transmission and/or reception between the base station and the UE may be called a Uu interface (such as an NR-Uu interface based on NR; such as an LTE-Uu interface based on LTE). The interface for wireless transmission and/or reception between UEs may be referred to as a PC5 interface.
为了支持在授权频谱和/或非授权频谱上的通信，需要解决一系列的问题，例如，信道接入(channel access)机制；又如，物理层信道和/或信号的结构；又如，物理层控制信息和/或信令流程(例如同步流程，又 如反馈和/或确定机制)；又如，更高层控制信息和/或信令流程；又如，资源的分配和/或管理；又如，不同系统间的共存。In order to support communications on licensed and/or unlicensed spectrum, a series of issues need to be addressed, such as channel access mechanism; the structure of physical layer channels and/or signals; physical layer control information and/or signaling processes (e.g., synchronization processes, etc.); Such as feedback and/or determination mechanism); such as higher-level control information and/or signaling process; such as allocation and/or management of resources; such as coexistence between different systems.

The collection There is only one SL bandwidth segment in and is always equal to 1. In this case, the SL bandwidth fraction The collection configured in Can be considered as SL carrier A set of transport resource pools of type 1 configured in .
可选地，所述集合CTX中只包含配置了类型一传输资源池的SL载波。例如，先根据一个或多个预定义和/或配置和/或预配置的参数确定所述集合CTX后，然后从所述集合CTX中移除未配置任何类型一传输资源池的SL载波。Optionally, the set C TX only includes SL carriers configured with a type 1 transmission resource pool. For example, after the set C TX is first determined according to one or more predefined and/or configured and/or preconfigured parameters, SL carriers that are not configured with any type 1 transmission resource pool are removed from the set C TX .
一个类型一传输资源池可以用于由网络(例如，基站)调度的(一个或多个)SL传输(例如，基于SL资源分配模式1的SL传输)。例如，所述(一个或多个)SL传输所在的SL资源池可以是SL载波 中的SL带宽片段中的类型一传输资源池集合中的一个SL资源池 A type 1 transmission resource pool may be used for (one or more) SL transmissions (e.g., SL transmissions based on SL resource allocation mode 1) scheduled by a network (e.g., a base station). For example, the SL resource pool where the (one or more) SL transmissions are located may be a SL carrier SL bandwidth fragment in Type-1 transport resource pool set A SL resource pool in
当SL传输(或者说SL传输的资源)由网络(例如，基站)调度时(例如，当UE配置为使用SL资源分配模式1时)，UE可以监测(monitor)一个或多个用于调度SL传输的DCI格式(例如分别称为“第一SL DCI格式”，“第二SL DCI格式”，……；具体地，例如，所述一个或多个 用于调度SL传输的DCI格式可以包括DCI格式3_0)，并在接收到的相应的DCI中指示的一个或多个SL资源上分别执行SL传输。另外，在同一个搜索空间集合中，可以配置一个或多个其他DCI格式(例如，用于调度DL传输的一个或多个DCI格式，和/或用于调度UL传输的一个或多个DCI格式，和/或用于其他用途的一个或多个DCI格式)。When SL transmission (or resources for SL transmission) is scheduled by the network (e.g., a base station) (e.g., when the UE is configured to use SL resource allocation mode 1), the UE may monitor one or more DCI formats for scheduling SL transmission (e.g., respectively referred to as “first SL DCI format”, “second SL DCI format”, etc.; specifically, for example, the one or more DCI formats for scheduling SL transmission The DCI format for scheduling SL transmission may include DCI format 3_0), and SL transmission is performed on one or more SL resources indicated in the corresponding received DCI. In addition, in the same search space set, one or more other DCI formats (for example, one or more DCI formats for scheduling DL transmission, and/or one or more DCI formats for scheduling UL transmission, and/or one or more DCI formats for other purposes) may be configured.
在一种PDCCH(Physical downlink control channel，物理下行控制信道)和/或DCI设计中，UE需要执行“盲检”(blind detection)以确定一个PDCCH传输中实际携带的DCI(例如，UE需要确定所述DCI对应的DCI格式；又如，UE需要确定所述DCI对应的RNTI(Radio Network Temporary Identifier，无线网络临时标识符))。在执行“盲检”(以及正确接收DCI)前，UE需要分别确定在相应的搜索空间集合中需要监测的所有DCI格式的大小(例如，以比特个数表示的大小)。不同DCI格式的大小可以相同，或者不同。若两个不同的DCI格式的大小相同，则他们对应同一个“DCI大小”(或者称为“DCI格式大小”)。为保持合理的UE实现复杂度，UE需要“盲检”的总的“DCI大小”的个数不应该太大。在执行“盲检”时，每一个“DCI大小”可以认为是UE对一个PDCCH传输中所携带的DCI所对应的DCI格式的大小的一个假定(hypothesis)。In a PDCCH (Physical downlink control channel) and/or DCI design, the UE needs to perform "blind detection" to determine the DCI actually carried in a PDCCH transmission (for example, the UE needs to determine the DCI format corresponding to the DCI; for example, the UE needs to determine the RNTI (Radio Network Temporary Identifier) corresponding to the DCI). Before performing "blind detection" (and correctly receiving DCI), the UE needs to separately determine the sizes of all DCI formats that need to be monitored in the corresponding search space set (for example, the size expressed in the number of bits). The sizes of different DCI formats can be the same or different. If the sizes of two different DCI formats are the same, they correspond to the same "DCI size" (or called "DCI format size"). To maintain a reasonable UE implementation complexity, the total number of "DCI sizes" that the UE needs to "blind detect" should not be too large. When performing "blind detection", each "DCI size" can be considered as a hypothesis of the UE regarding the size of the DCI format corresponding to the DCI carried in a PDCCH transmission.
所述一个或多个用于调度SL传输的DCI格式可以与相应的SL载波所在的频谱有关，或者无关。例如，对授权频谱和非授权频谱分别定义和/或配置和/或预配置相应的“第一SL DCI格式”，“第二SL DCI格式”，……，等等。又如，只定义或配置或预配置一个“第一SL DCI格式”，一个“第 二SL DCI格式”，……，其中，每个SL DCI格式可以调度一个授权频谱上的(一个或多个)SL载波中的(一个或多个)SL传输，或者调度一个非授权频谱上的(一个或多个)SL载波中的(一个或多个)SL传输。The one or more DCI formats for scheduling SL transmission may be related to the spectrum where the corresponding SL carrier is located, or may be unrelated. For example, corresponding "first SL DCI format", "second SL DCI format", ..., etc. are defined and/or configured and/or pre-configured for the licensed spectrum and the unlicensed spectrum, respectively. For another example, only one "first SL DCI format" and one "second SL DCI format" are defined, configured or pre-configured. Two SL DCI formats",..., where each SL DCI format can schedule (one or more) SL transmissions in (one or more) SL carriers on a licensed spectrum, or schedule (one or more) SL transmissions in (one or more) SL carriers on an unlicensed spectrum.

对n∈{0，1，...，NS101-2}，可以认为是为所述第一SL DCI格式确定的一个“临时大小”(interim size)。For n∈{0, 1, ..., N S101 -2}, It can be considered as an “interim size” determined for the first SL DCI format.
对n0∈{0，1，...，NS101-2}，可以小于或者等于或者大于 For n 0 ∈ {0, 1, ..., N S101 -2}, Can be less than or equal to or greater than
例如，在子步骤(其中n1是一个满足0≤n1≤NS101-1的整数，例如n1＝0，又如n1＝1)中，对所述第一SL DCI格式执行“零填充”(zero padding)操作，直至所述第一SL DCI格式的负荷大小等于第一参考大小。可选地，在所述子步骤中，若满足第一零填充条件，则执行所述零填充操作，直至所述第一SL DCI格式的负荷大小等于所述第一参考大小。可选地，在所述子步骤中，当且仅当满足所述第一零填充条件时，执行所述零填充操作，直至所述第一SL DCI格式的负荷大小等于所述第一参考大小。For example, in the substep (where n 1 is an integer satisfying 0≤n 1 ≤NS101-1 , such as n 1 =0, and such as n 1 =1), a "zero padding" operation is performed on the first SL DCI format until the payload size of the first SL DCI format is equal to the first reference size. Optionally, in the sub-step In the sub-step, if the first zero filling condition is met, the zero filling operation is performed until the payload size of the first SL DCI format is equal to the first reference size. In the embodiment, when and only when the first zero filling condition is met, the zero filling operation is performed until the payload size of the first SL DCI format is equal to the first reference size.
又如，在子步骤(其中n2是一个满足0≤n2≤NS101-1的整数，例如n2＝0，又如n2＝1)中，确定的值，例如，等于所述第一参考大小。需要指出的是，所述子步骤中不存在零填充操作。所述子步骤可以对应所述通信节点在执行所述步骤S101时无法确定所述 第一SL DCI格式的一个或多个字段的大小的情况，例如，当所述通信节点是一个UE(即DCI的接收者)、且所述SL载波c和/或所述SL带宽片段b和/或所述SL资源池u由所述第一SL DCI格式指示时；在这种情况下，所述通信节点在执行所述步骤S101时，由于还未执行DCI接收，所以可能无法确定将要接收的DCI中所指示的所述SL载波c和/或所述SL带宽片段b和/或所述SL资源池u，从而也无法确定所述第一SL DCI格式中大小依赖于所述SL载波c所对应的SL载波配置和/或所述SL带宽片段b所对应的SL带宽片段配置和/或所述SL资源池u所对应的SL资源池配置的(一个或多个)字段(例如载波指示器字段，又如带宽片段指示器字段，又如资源池指示器字段)的大小，进而无法确定所述第一SL DCI格式的信息比特的个数，也就无法确定需要填充的零比特的个数。另一方面，若所述第一参考大小不依赖于所述SL载波c和/或所述SL带宽片段b和/或所述SL资源池u，则所述通信节点仍然可以确定的值。可选地，在所述子步骤中，若满足所述第一零填充条件，则确定的值。可选地，在所述子步骤中，当且仅当满足所述第一零填充条件时，确定的值。For example, in the substep (where n 2 is an integer satisfying 0≤n 2 ≤N S101 -1, such as n 2 =0, or n 2 =1), determine For example, is equal to the first reference size. It should be noted that the sub-step There is no zero-filling operation in the sub-step The communication node may be unable to determine the The situation of the size of one or more fields of the first SL DCI format, for example, when the communication node is a UE (i.e., a recipient of the DCI) and the SL carrier c and/or the SL bandwidth segment b and/or the SL resource pool u are indicated by the first SL DCI format; in this case, when the communication node executes the step S101, since the DCI reception has not yet been performed, it may not be possible to determine the SL carrier c and/or the SL bandwidth segment b and/or the SL resource pool u indicated in the DCI to be received, and thus it is also impossible to determine the size of (one or more) fields (e.g., a carrier indicator field, a bandwidth segment indicator field, and a resource pool indicator field) in the first SL DCI format whose size depends on the SL carrier configuration corresponding to the SL carrier c and/or the SL bandwidth segment configuration corresponding to the SL bandwidth segment b and/or the SL resource pool configuration corresponding to the SL resource pool u, and thus it is impossible to determine the number of information bits of the first SL DCI format, and it is also impossible to determine the number of zero bits that need to be filled. On the other hand, if the first reference size does not depend on the SL carrier c and/or the SL bandwidth segment b and/or the SL resource pool u, the communication node can still determine Optionally, in the sub-step If the first zero-filling condition is met, then determine Optionally, in the sub-step If and only if the first zero-filling condition is met, determine The value of .
又如，在子步骤(其中n3是一个满足0≤n3≤NS101-1的整数，例如n3＝0，又如n3＝1)中，对所述第一SL DCI格式执行零填充操作，直至所述第一SL DCI格式的负荷大小等于第二参考大小。可选地，在所述子步骤中，若满足所述第一零填充条件，则执行所述零填充操作，直至所述第一SL DCI格式的负荷大小等于所述第二参考大小。可选地，在所述子步骤中，当且仅当满足所述第一零填充条件时，执行所述零 填充操作，直至所述第一SL DCI格式的负荷大小等于所述第二参考大小。For example, in the substep (where n 3 is an integer satisfying 0≤n 3 ≤NS101-1 , such as n 3 =0, and such as n 3 =1), a zero padding operation is performed on the first SL DCI format until the payload size of the first SL DCI format is equal to the second reference size. Optionally, in the sub-step In the sub-step, if the first zero padding condition is met, the zero padding operation is performed until the payload size of the first SL DCI format is equal to the second reference size. In the embodiment, if and only if the first zero filling condition is satisfied, the zero filling is performed. The padding operation is performed until the payload size of the first SL DCI format is equal to the second reference size.
