Description

无线通信资源指示方法、装置和系统
本申请要求在2019年08月16日提交中国专利局、申请号为201910760868.4的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信网络，例如涉及一种无线通信资源指示方法、装置和系统。
背景技术
在第五代移动通信(5th Generation，5G)新空口(New Radio，NR)中，提供了设备到设备(Device to Device，D2D)通信方式，即终端之间可以直接建立通信连接进行通信，而无需通过基站或其他接入节点。D2D通信例如包括车辆到其他设备(Vehicle to X，V2X)等多种形式。
在D2D通信中，网络覆盖内的用户设备(User Equipment，UE)根据基站的配置确定边链路(sidelink)通信的帧结构和资源池，网络覆盖外的UE根据预配置确定帧结构和资源池。对于半覆盖场景，即网络覆盖边缘区域，为了实现覆盖内UE和覆盖外UE之间的相互通信，也为了避免覆盖外UE发送的信号在基站接收侧造成干扰，覆盖外的UE需要知道覆盖内配置的帧结构信息(上行/下行时分双工配置(UpLink/DownLink Time Division Duplex configuration，UL/DL TDD configuartion)信息)和资源池信息。
而在已经公布的相关标准中已经确定不支持UE转发资源池配置信息或资源配置信息。同时，在NR中，UL/DL TDD configuartion参数包括小区特征(cell specific)参数和用户设备特征(UE specific)参数，如果在物理边链路广播信道(Physical Sidelink Broadcast Channel，PSBCH)中指示UL/DL TDD configuartion参数，指示所需的开销太大，难以实现。

具体实施方式
下文中将结合附图对本申请的实施例进行说明。
图1为一实施例提供的一种无线通信资源指示方法的流程图，如图1所示，本实施例提供的方法包括如下步骤。
步骤S1010，确定sidelink潜在时域资源配置信息，sidelink潜在时域资源配置信息用于指示可用于sidelink资源映射的时域资源范围。
本实施例提供的无线通信资源指示方法应用于进行D2D通信的第一UE，第一UE为位于接入节点覆盖范围内，第一UE与位于接入节点覆盖范围外的第二UE进行D2D通信。本申请下述多个实施例中均以第一UE和第二UE进行NR V2X通信为例，对第一UE和第二UE所进行的D2D通信中无线通信资源指示方法进行说明。第一UE和第二UE通过sidelink进行通信，在进行通信之前，第一UE和第二UE需要确定通信所使用的传输资源，也即需要进行传输资源的调度。由于第一UE位于接入节点的覆盖范围内，因此第一UE能够接收到接入节点发送的多种配置信息，那么第一UE将能够获知网络分配给sidelink所使用的资源。第二UE由于位于接入节点的覆盖范围之外，因此第二节点无法接收到接入节点发送的配置信息，那么第一节点就需要向第二UE发送用于sidelink通信所使用的通信资源的配置信息。
但是相关标准中已经确定不支持V2X通信中的UE转发资源池配置信息或资源配置信息，而与资源配置相关的资源配置信息，上行/下行时分双工配置信息UL/DL TDD configuartion信息(也即时分双工-上行-下行-配置信息(TDD-UL-DL-Config))包括cell specific(也即时分双工-上行-下行-通用配置(TDD-UL-DL-ConfigCommon))和ue specific(也即时分双工-上行-下行-专用配置(TDD-UL-DL-ConfigDedicated))，若第一UE在PSBCH中指示上行/下行时分双工配置信息所需开销太大，难以实现，而若第一UE不指示第二UE资源配置信息，那么第二UE进行sidelink通信所使用的传输资源可能对蜂窝通信产生干扰。
在本实施例中，为了解决上述问题，并不在PSBCH中指示完整的示上行/下行时分双工配置信息，而是仅发送sidelink潜在时域资源配置信息。sidelink潜在时域资源配置信息是可能被用于进行sidelink通信所使用的时域资源的范围的相关信息。也就是第一UE并不通过PSBCH向第二UE发送完整的sidelink资源配置信息，而是仅发送能够指示sidelink通信所使用的时域资源范围的相关信息，从而达到减少传输资源配置信息的开销的目的，使得通过PSBCH发送传输资源配置信息变为可能。
首先，需要先确定sidelink潜在时域资源配置信息，sidelink潜在时域资源配置信息用于指示可用于sidelink资源映射的时域资源范围，sidelink潜在时域资源配置信息相当于UL/DL TDD configuartion信息中的cell specific参数，但 sidelink潜在时域资源配置信息中并不包括完整的cell specific参数，sidelink潜在时域资源配置信息中所包括的信息只要能够指示可用于sidelink资源映射的时域资源范围即可，可以是一个或多个参数的组合。
在一实施例中，sidelink潜在时域资源配置信息可以包括：sidelink潜在时域资源的时域配置周期、sidelink潜在时域资源的起始位置和/或sidelink潜在时域资源的起始位置的偏移值。sidelink潜在时域资源的时域配置周期是指可用于sidelink通信的时域资源范围，可以是以时隙(slot)为粒度的，也可以是以任一时间长度为粒度的，例如毫秒(ms)。sidelink潜在时域资源的时域配置周期是众多时域资源的集合，包括可用于sidelink传输的资源和不可用于sidelink传输的资源，每个sidelink潜在时域资源的时域配置周期内的资源配置和排列方式相同。sidelink潜在时域资源的起始位置是指可用于sidelink传输的资源在sidelink潜在时域资源的时域配置周期内的起始位置，可以是以时隙为粒度，也可以是以时间为粒度，可用于sidelink传输的资源在sidelink潜在时域资源的时域配置周期内从起始位置开始直到周期末尾。或者还可以不指示sidelink潜在时域资源的起始位置而是指示sidelink潜在时域资源起始位置的偏移值，也就是从每个sidelink潜在时域资源的时域配置周期的起始位置到sidelink潜在时域资源起始位置的偏移值，同样可以以时隙为粒度或者以时间为粒度，可用于sidelink传输的资源在sidelink潜在时域资源的时域配置周期内从周期起点增加偏移值开始直到周期末尾。
在一实施例中，sidelink潜在时域资源配置信息包括：sidelink的潜在有效时域资源范围。sidelink的潜在有效时域资源范围表示sidelink的潜在有效时域资源在sidelink潜在时域资源的时域配置周期内的范围。sidelink潜在时域资源的时域配置周期包括在sidelink的潜在有效时域资源范围内，也可以通过其他方式另外指示，或者是预配置的。sidelink的潜在有效时域资源范围可以采用多种方式指示，例如sidelink的潜在有效时域资源范围包括sidelink潜在时域资源的时域配置周期、在sidelink潜在时域资源的时域配置周期中的有效时域资源的起始位置和sidelink潜在时域资源的有效时域长度。起始位置和有效时域长度可以以时隙为粒度也可以以时间为粒度。起始位置和有效时域长度还可以对时隙或时间进行量化后指示，比如以5个时隙或5ms为指示粒度。
在一实施例中，sidelink潜在时域资源配置信息包括：sidelink的潜在有效时域资源范围，sidelink的潜在有效时域资源范围包括sidelink潜在时域资源的潜在有效时隙数，或者以时间为单位的sidelink潜在时域资源的有效时间范围。sidelink的潜在有效时域资源范围表示sidelink的潜在有效时域资源在sidelink潜在时域资源的时域配置周期内的范围。sidelink潜在时域资源的时域配置周期包括在sidelink的潜在有效时域资源范围内，也可以通过其他方式另外指示，或者 是预配置的。也就是sidelink的潜在有效时域资源范围可以仅以有效时隙数或有效时间范围进行指示，而在sidelink潜在时域资源的时域配置周期中的有效时域资源的起始位置可以是从sidelink潜在时域资源的时域配置周期的起点开始或者根据预配置信息确定。
在一实施例中，sidelink潜在时域资源配置信息包括：sidelink潜在时域资源配置信息在预设的sidelink潜在时域资源配置表中的索引值，sidelink潜在时域资源配置信息包括时分双工上行下行时隙配置信息。在第一UE和第二UE中可以预设sidelink潜在时域资源配置表，sidelink潜在时域资源配置表中包括一组或多组sidelink潜在时域资源配置信息，每组sidelink潜在时域资源配置信息包括时分双工上行下行时隙配置信息，或者还可以包括sidelink潜在时域资源的时域配置周期等信息。sidelink潜在时域资源配置表中包括的每组信息相当于完整的UL/DL TDD configuartion信息，但由于sidelink潜在时域资源配置信息仅为sidelink潜在时域资源配置信息在预设的sidelink潜在时域资源配置表中的索引值，那么仅需有限的开销即可传输索引值，而无需消耗过多的开销。
在上述多个实施例中，sidelink潜在时域资源配置信息还包括：子载波间隔或numerology信息。numerology信息包括子载波间隔，符号长度，循环前缀(Cyclic Prefix，CP)长度等。子载波间隔或numerology信息用于指示sidelink潜在时域资源的配置信息的子载波。子载波间隔或numerology信息可以包含在sidelink潜在时域资源的配置信息中，也可以单独指示，或者根据预定义确定。传统的无线通信系统中子载波间隔是固定的，但在5G NR中提出了可变子载波间隔的技术，因此在可变子载波间隔的情况下，sidelink潜在时域资源配置信息还可以包括子载波间隔或numerology信息，从而对子载波间隔进行指示。
在一实施例中，子载波间隔或numerology信息根据网络侧配置信息确定；和/或，子载波间隔或numerology信息包含在sidelink潜在时域资源配置信息中；和/或，子载波间隔或numerology信息与sidelink潜在时域资源配置信息对应的索引值有显式或隐式映射关系。
步骤S1020，通过PSBCH发送sidelink潜在时域资源配置信息。
在确定sidelink潜在时域资源配置信息之后，第一UE即可通过PSBCH向第二UE发送sidelink潜在时域资源配置信息。那么当第二UE接收到sidelink潜在时域资源配置信息后，即可确定可用于sidelink资源映射的时域资源范围，也就是确定了进行sidelink传输所使用的传输资源的范围，那么第二UE可以在确定的资源范围内选择任意资源与第一UE进行sidelink通信。可用于sidelink资源映射的时域资源范围仅表示一个时域传输资源的范围，相当于一个资源池，而第二UE在资源池中选择哪些传输资源进行上行传输或下行传输，可以根据第 二UE中预配置的信息，在可用于sidelink资源映射的时域资源范围内进行映射而得到，第一UE中也具有与第二UE相同的预配置信息，从而第一UE能够在可用于sidelink资源映射的时域资源范围内映射得到与第二UE确定的相同的传输资源。
本实施例提供的无线通信资源指示方法，在确定sidelink潜在时域资源配置信息后，通过PSBCH发送sidelink潜在时域资源配置信息，sidelink潜在时域资源配置信息用于指示可用于sidelink资源映射的时域资源范围，使得D2D通信中的覆盖范围内的UE能够向覆盖范围外的UE指示sidelink通信所使用的资源，避免了sidelink通信对蜂窝通信的干扰。
图1所示实施例中，确定了sidelink潜在时域资源配置信息，并通过PSBCH发送了sidelink潜在时域资源配置信息，那么第一UE和第二UE可以确定可用于sidelink资源映射的时域资源范围。那么为了进一步地在可用于sidelink资源映射的时域资源范围中确定sidelink可用的时域资源，还可以在第一UE和第二UE中预配置sidelink时域资源在sidelink潜在时域资源中的映射方式。sidelink可用的时域资源根据sidelink时域资源在sidelink潜在时域资源中的映射方式在sidelink潜在时域资源配置信息指示的可用于sidelink资源映射的时域资源范围内确定。也就是根据预配置的映射方式，在sidelink潜在时域资源配置信息指示的可用于sidelink资源映射的时域资源范围中确定sidelink可用的时域资源，从而准确地确定sidelink可用的时域资源，包括上行资源和下行资源。
在一实施例中，sidelink时域资源在sidelink潜在时域资源中的映射方式为采用位图(bitmap)的方式在可用于sidelink资源映射的时域资源范围内映射。Bitmap映射到sidelink潜在时域资源包括两种方法：
方法一：Bitmap以sidelink潜在时域资源配置周期的起始位置为起点进行映射，如果预配置的bitmap的周期小于sidelink潜在时域资源配置周期，则bitmap重复映射，直到完成sidelink潜在时域资源配置周期的映射。如果sidelink潜在时域资源配置周期与bitmap周期不成整数倍关系，那么采取对超出sidelink潜在时域资源配置周期的bitmap的部分比特串进行截断，或者对不足一个bitmap周期的sidelink潜在时域资源配置范围放弃bitmap映射。或者，预配置bitmap时，使bitmap的周期能被20ms整除。
如果bitmap周期大于sidelink潜在时域资源配置周期，则对超出sidelink潜在时域资源配置周期的bitmap的部分比特串进行截断。
在sidelink潜在时域资源之外的资源，Bitmap无效，即使为1，也不作为可用于sidelink资源映射的时域资源范围。
方法二：Bitmap在sidelink潜在时域资源上映射。从sidelink潜在时域资源配置周期的起始位置或基于偏移量offset开始映射；从sidelink潜在时域资源配置信息中包含的sidelink潜在时域资源配置中的sidelink潜在符号或sidelink潜在时隙开始映射。
方法一和方法二也可以组合使用。
图2为一实施例提供的另一种无线通信资源指示方法的流程图，如图2所示，本实施例提供的方法包括如下步骤。
步骤S2010，通过PSBCH接收sidelink潜在时域资源配置信息。
本实施例提供的无线通信资源指示方法应用于进行D2D通信的第二UE，第二UE为位于接入节点覆盖范围外，第二UE与位于接入节点覆盖范围内的第一UE进行D2D通信。第一UE和第二UE通过sidelink进行通信，在进行通信之前，第一UE和第二UE需要确定通信所使用的传输资源，也即需要进行传输资源的调度。由于第一UE位于接入节点的覆盖范围内，因此第一UE能够接收到接入节点发送的多种配置信息，那么第一UE将能够获知网络分配给sidelink所使用的资源。第二UE由于位于接入节点的覆盖范围之外，因此第二节点无法接收到接入节点发送的配置信息，那么第二节点就需要接收第一UE发送的用于sidelink通信所使用的通信资源的配置信息。
但是相关标准中已经确定不支持V2X通信中的UE转发资源池配置信息或资源配置信息，而与资源配置相关的资源配置信息，上行/下行时分双工配置信息UL/DL TDD configuartion信息(也即时分双工-上行-下行-配置信息(TDD-UL-DL-Config))包括cell specific(也即时分双工-上行-下行-通用配置(TDD-UL-DL-ConfigCommon))和ue specific(也即时分双工-上行-下行-专用配置(TDD-UL-DL-ConfigDedicated))，若第一UE在PSBCH中指示上行/下行时分双工配置信息所需开销太大，难以实现，而若第一UE不指示第二UE资源配置信息，那么第二UE进行sidelink通信所使用的传输资源可能对蜂窝通信产生干扰。
在本实施例中，为了解决上述问题，并不在PSBCH中指示完整的示上行/下行时分双工配置信息，而是仅发送sidelink潜在时域资源配置信息。sidelink潜在时域资源配置信息是可能被用于进行sidelink通信所使用的时域资源的范围的相关信息。也就是第一UE并不通过PSBCH向第二UE发送完整的sidelink资源配置信息，而是仅发送能够指示sidelink通信所使用的时域资源范围的相关信息，从而达到减少传输资源配置信息的开销的目的，使得通过PSBCH发送传输资源配置信息变为可能。
第二UE通过PSBCH接收第一UE发送的sidelink潜在时域资源配置信息，sidelink潜在时域资源配置信息用于指示可用于sidelink资源映射的时域资源范围，sidelink潜在时域资源配置信息相当于UL/DL TDD configuartion信息中的cell specific参数，但sidelink潜在时域资源配置信息中并不包括完整的cell specific参数，sidelink潜在时域资源配置信息中所包括的信息只要能够指示可用于sidelink资源映射的时域资源范围即可，可以是一个或多个参数的组合。
在一实施例中，sidelink潜在时域资源配置信息可以包括：sidelink潜在时域资源的时域配置周期、sidelink潜在时域资源的起始位置和/或sidelink潜在时域资源的起始位置的偏移值。sidelink潜在时域资源的时域配置周期是指可用于sidelink通信的时域资源范围，可以是以时隙(slot)为粒度的，也可以是以任一时间长度为粒度的，例如毫秒(ms)。sidelink潜在时域资源的时域配置周期是众多时域资源的集合，包括可用于sidelink传输的资源和不可用于sidelink传输的资源，每个sidelink潜在时域资源的时域配置周期内的资源配置和排列方式相同。sidelink潜在时域资源的起始位置是指可用于sidelink传输的资源在sidelink潜在时域资源的时域配置周期内的起始位置，可以是以时隙为粒度，也可以是以时间为粒度，可用于sidelink传输的资源在sidelink潜在时域资源的时域配置周期内从起始位置开始直到周期末尾。或者还可以不指示sidelink潜在时域资源的起始位置而是指示sidelink潜在时域资源起始位置的偏移值，也就是从每个sidelink潜在时域资源的时域配置周期的起始位置到sidelink潜在时域资源起始位置的偏移值，同样可以以时隙为粒度或者以时间为粒度，可用于sidelink传输的资源在sidelink潜在时域资源的时域配置周期内从周期起点增加偏移值开始直到周期末尾。
在一实施例中，sidelink潜在时域资源配置信息包括：sidelink的潜在有效时域资源范围。sidelink的潜在有效时域资源范围表示sidelink的潜在有效时域资源在sidelink潜在时域资源的时域配置周期内的范围。sidelink潜在时域资源的时域配置周期包括在sidelink的潜在有效时域资源范围内，也可以通过其他方式另外指示，或者是预配置的。sidelink的潜在有效时域资源范围可以采用多种方式指示，例如sidelink的潜在有效时域资源范围包括sidelink潜在时域资源的时域配置周期、在sidelink潜在时域资源的时域配置周期中的有效时域资源的起始位置和sidelink潜在时域资源的有效时域长度。起始位置和有效时域长度可以以时隙为粒度也可以以时间为粒度。起始位置和有效时域长度还可以对时隙或时间进行量化后指示，比如以5个时隙或5ms为指示粒度。
在一实施例中，sidelink潜在时域资源配置信息包括：sidelink的潜在有效时域资源范围，sidelink的潜在有效时域资源范围包括sidelink潜在时域资源的潜在有效时隙数，或者以时间为单位的sidelink潜在时域资源的有效时间范围。 sidelink的潜在有效时域资源范围表示sidelink的潜在有效时域资源在sidelink潜在时域资源的时域配置周期内的范围。sidelink潜在时域资源的时域配置周期包括在sidelink的潜在有效时域资源范围内，也可以通过其他方式另外指示，或者是预配置的。也就是sidelink的潜在有效时域资源范围可以仅以有效时隙数或有效时间范围进行指示，而在sidelink潜在时域资源的时域配置周期中的有效时域资源的起始位置可以是从sidelink潜在时域资源的时域配置周期的起点开始或者根据预配置信息确定。
在一实施例中，sidelink潜在时域资源配置信息包括：sidelink潜在时域资源配置信息在预设的sidelink潜在时域资源配置表中的索引值，sidelink潜在时域资源配置信息包括时分双工上行下行时隙配置信息。在第一UE和第二UE中可以预设sidelink潜在时域资源配置表，sidelink潜在时域资源配置表中包括一组或多组sidelink潜在时域资源配置信息，每组sidelink潜在时域资源配置信息包括时分双工上行下行时隙配置信息，或者还可以包括sidelink潜在时域资源的时域配置周期等信息。sidelink潜在时域资源配置表中包括的每组信息相当于完整的UL/DL TDD configuartion信息，但由于sidelink潜在时域资源配置信息仅为sidelink潜在时域资源配置信息在预设的sidelink潜在时域资源配置表中的索引值，那么仅需有限的开销即可传输索引值，而无需消耗过多的开销。
在上述多个实施例中，sidelink潜在时域资源配置信息还包括：子载波间隔或numerology信息。numerology信息包括子载波间隔，符号长度，循环前缀(CP)长度等。子载波间隔或numerology信息用于指示sidelink潜在时域资源的配置信息的子载波。子载波间隔或numerology信息可以包含在sidelink潜在时域资源的配置信息中，也可以单独指示，或者根据预定义确定。传统的无线通信系统中子载波间隔是固定的，但在5G NR中提出了可变子载波间隔的技术，因此在可变子载波间隔的情况下，sidelink潜在时域资源配置信息还可以包括子载波间隔或numerology信息，从而对子载波间隔进行指示。
在一实施例中，子载波间隔或numerology信息根据网络侧配置信息确定；和/或，子载波间隔或numerology信息包含在sidelink潜在时域资源配置信息中；和/或，子载波间隔或numerology信息与sidelink潜在时域资源配置信息对应的索引值有显式或隐式映射关系。
步骤S2020，根据sidelink潜在时域资源配置信息确定可用于sidelink资源映射的时域资源范围。
当第二UE接收到sidelink潜在时域资源配置信息后，即可确定可用于sidelink资源映射的时域资源范围，也就是确定了进行sidelink传输所使用的传输资源的范围，那么第二UE可以在确定的资源范围内选择任意资源与第一UE 进行sidelink通信。可用于sidelink资源映射的时域资源范围仅表示一个时域传输资源的范围，相当于一个资源池，而第二UE在资源池中选择哪些传输资源进行上行传输或下行传输，可以根据第二UE中预配置的信息，在可用于sidelink资源映射的时域资源范围内进行映射而得到，第一UE中也具有与第二UE相同的预配置信息，从而第一UE能够在可用于sidelink资源映射的时域资源范围内映射得到与第二UE确定的相同的传输资源。
本实施例提供的无线通信资源指示方法，通过PSBCH接收sidelink潜在时域资源配置信息后，根据sidelink潜在时域资源配置信息确定可用于sidelink资源映射的时域资源范围，使得D2D通信中的覆盖范围外的UE能够接收覆盖范围内的UE发送的指示sidelink通信所使用的资源，避免了sidelink通信对蜂窝通信的干扰。
图2所示实施例中，根据sidelink潜在时域资源配置信息确定可用于sidelink资源映射的时域资源范围后。为了进一步地在可用于sidelink资源映射的时域资源范围中确定sidelink可用的时域资源，还可以在第一UE和第二UE中预配置sidelink时域资源在sidelink潜在时域资源中的映射方式。第二UE可以根据预配置的sidelink时域资源在sidelink潜在时域资源中的映射方式，在可用于sidelink资源映射的时域资源范围内确定sidelink可用时域资源。
在一实施例中，sidelink时域资源在sidelink潜在时域资源中的映射方式为采用位图bitmap的方式在可用于sidelink资源映射的时域资源范围内映射。
下面以几个实施例对本申请实施例提供的无线通信资源指示方法进行说明。
实施例一：
图3为一实施例提供的一种无线通信资源指示方法的时隙资源配置示意图，如图3所示，本实施例的指示方法是描述指示Cell specific参数TDD-UL-DL-ConfigCommon配置信息中对sidelink通信有效的信息配置，例如包括在TDD-UL-DL-ConfigCommon配置信息的配置周期中的sidelink通信的有效范围的起始位置，和/或sidelink通信的有效长度。起始位置和时域长度可以是以slot为粒度，也可以是以时间(比如毫秒)为粒度，还可以对时间进行量化后指示，比如，以5个slot或5ms为指示粒度，指示的内容为配置周期中指示粒度的个数和/或对应起始位置的指示粒度的序号。
另一个实施例，与指示的信息对应的子载波间隔或numerology信息可以包含在指示信息中，或者默认与接收端UE的子载波间隔或numerology信息一致，或者与接收端UE参考的子载波间隔或numerology信息一致。
以图3为例说明，指示信息的内容包括sidelink通信有效范围的起始位置，值为M*5*slot，表示以5倍的slot为粒度进行指示，假设M＝3，那么根据指示信息，可确定sidelink通信的有效范围在TDD-UL-DL-ConfigCommon配置周期中的起始位置为15个slot处。或者，指示信息的内容包括sidelink通信有效范围的长度，值为L*5ms，表示以5ms为粒度进行指示，假设L＝2，那么根据指示信息，可确定sidelink通信的有效范围在TDD-UL-DL-ConfigCommon配置周期中的长度为10ms。结合TDD-UL-DL-ConfigCommon配置的结构，可确定TDD-UL-DL-ConfigCommon配置周期中后10ms为sidelink通信的有效范围。子载波间隔信息根据指示信息确定，或者根据接收端UE的子载波间隔信息或numerology信息确定，或者根据参考子载波间隔信息或numerology信息确定。
实施例二：
本实施例的指示方法是描述指示Cell specific参数TDD-UL-DL-ConfigCommon配置信息中对sidelink通信有效的配置信息，例如指示一组TDD-UL-DL-ConfigCommon配置信息的值，比如，下行-上行-传输周期(DL-UL-TransmissionPeriodicity)为10ms，下行时隙数(nrofDownlinkSlots)为128，下行符号数(nrofDownlinkSymbols)为6，上行时隙数(nrofUplinkSlots)为512，上行符号数(nrofUplinkSymbols)为8。对所有或部分的TDD-UL-DL-ConfigCommon配置信息组合，每一组都映射一个索引，指示信息中包含对应的索引值，根据指示信息中的索引值，可以映射到对应的TDD-UL-DL-ConfigCommon配置信息组合的参数配置值。TDD-UL-DL-ConfigCommon配置信息组合中的参数配置值可以包括TDD-UL-DL-ConfigCommon包含的所有参数值或部分参数的配置值。
另一个实施例，与指示的信息对应的子载波间隔或numerology信息可以包含在指示的配置信息组合中，或者与指示的索引值有对应关系，根据指示索引值可以确定对应的子载波间隔或numerology信息。或者默认与接收端UE的子载波间隔或numerology信息一致，或者与接收端UE参考的子载波间隔或numerology信息一致。
如表1所示，索引值index为0对应的配置信息组合中的参数配置值包括：nrofUplinkSymbols为x0，nrofUplinkSlots为y0，DL-UL-TransmissionPeriodicity为T0，以及子载波间隔或numerology信息n1。索引值index为8对应的配置信息组合中的参数配置值包括：nrofUplinkSymbols为x8，nrofUplinkSlots为y8，DL-UL-TransmissionPeriodicity为T1，以及子载波间隔或numerology信息n2。nrofUplinkSymbols表示全UL slot之前的slot中UL symbol的数量， nrofUplinkSlots表示全UL slot的数量，DL-UL-TransmissionPeriodicity为配置周期，子载波间隔信息n1和n2的值可以相等。

实施例三：
本实施例中，根据预配置信息确定sidelink通信的有效资源图样(pattern)，和/或根据sidelink潜在时域资源配置信息包含的UL/DL TDD配置信息，确定sidelink通信的资源池或资源。
UL/DL TDD配置信息包括但不限于NR配置信息中的TDD-UL-DL-ConfigCommon配置信息，参数包括以下至少之一：指示配置周期的参数DL-UL-TransmissionPeriodicity，指示全DL slot的数量的参数nrofDownlinkSlots，指示全DL slot之后的slot中DL symbol的数量的参数nrofDownlinkSymbols，指示全UL slot的数量的参数nrofUplinkSlots，指示全UL slot之前的slot中UL symbol的数量的参数nrofUplinkSymbols。
预配置信息指示sidelink通信的有效资源pattern的方式包括bitmap方式，以bit串的方式指示对应的sidelink通信资源是否有效，比如，bit串中的‘1’指示对应的无线资源为sidelink通信的有效资源，bit串中的‘0’指示对应的无线资源为sidelink通信的无效资源，这里的无线资源包括但不限于slot和symbol。
本实施例还包括：根据预配置信息指示的有效资源pattern，确定sidelink通信的有效资源的分布，根据sidelink潜在时域资源配置信息包含的UL/DL TDD 配置信息，确定sidelink通信的有效的帧结构，进一步确定sidelink通信的有效资源或资源池。
确定sidelink通信的有效资源或资源池的方法包括从UL/DL TDD配置周期起始位置开始映射指示有效资源pattern的bit串。如果bit串长度小于UL/DL TDD配置周期，则重复映射指示有效资源pattern的bit串，当最后一次映射的bit串超出UL/DL TDD配置周期时，超出的bit或比特串被截断掉，或者取消掉最后一次bit串的映射。
图4为一实施例提供的另一种无线通信资源指示方法的时隙资源配置示意图，如图4所示，在一个UL/DL TDD配置周期内，根据指示信息1确定sidelink通信的有效资源范围，指示在UL/DL TDD配置周期内对sidelink通信有效的UL/DL TDD配置。预配置信息指示的bitmap的比特串为001101...，指示sidelink通信有效资源的pattern，有效资源可以是slot或symbol。在UL/DL TDD配置周期内从起始位置开始重复映射，对于最后一个映射的比特串超出UL/DL TDD配置周期的比特，进行截断处理。作为实施例，也可以对最后一个映射的比特串取消映射处理。通过在UL/DL TDD配置周期内映射预配置信息指示的比特串，可以确定在sidelink有效的UL/DL TDD配置范围内，可用于sidelink通信的资源，或确定sidelink通信的资源池。
另一个例子，预配置的有效资源pattern的bit串中的bit指示的资源与蜂窝通信(比如NR)的下行链路DL资源重叠，则对应的时域资源不作为sidelink通信的可用资源。
实施例四：
本实施例描述一种预配置指示sidelink通信的有效资源的方法，预配置一串bitmap，用于指示sidelink通信的有效资源，比如，比特位‘1’指示对应的slot或symbol为sidelink有效资源，比特位‘0’指示对应的slot或symbol不是sidelink有效资源。
例如，bitmap指示的有效范围为UL/DL TDD配置周期，在一个UL/DL TDD配置周期内，从起始位置开始映射，如果比特位‘1’映射的slot或symbol为sidelink通信有效的帧结构，如果比特位‘1’映射的slot或symbol在对sidelink通信有效的UL/DL TDD配置范围内，那么，比特位‘1’映射的slot或symbol为sidelink通信的有效资源或资源池内的资源。
例如，预配置指示的bitmap长度为20ms的整数倍，或者能够被20ms整除。
另一个例子，预配置的bitmap中的bit指示的资源与蜂窝通信(比如NR) 的下行链路DL资源重叠，则对应的时域资源不作为sidelink通信的可用资源。
