Description

一种资源请求的发送方法、用户设备和基站 技术领域
本申请涉及通信领域，尤其涉及一种资源请求的发送方法、用户设备和基站。
背景技术
随着第五代移动通信技术(5-Generation mobile communication technology，5G)的讨论，4G长期演进(Long Term Evolution，LTE)中已经达到的系统结构和接入流程可以继续被采纳。一方面，由于通信系统是后向兼容的，后来研发的新技术倾向于兼容之前已经标准化的技术，另一方面，由于4G LTE已经存在大量的现有设计，如果为了达到兼容4G LTE中的设计，需要牺牲掉5G中的很多技术的灵活度，从而会降低5G技术的性能。因此，在3GPP中提出了4G和5G并行研究，不考虑后向兼容的技术讨论，这种研究下的通信协议被称为5G新通信协议(New Radio，NR)。
在5G NR的讨论中，短时长上行控制信道/短时长物理上行控制信令(short Physical Uplink Control Channel，short PUCCH)可以位于每个时隙的末尾1至2个符号上。如图1所示，可以将每个时隙分为三部分，第一部分为下行控制(Downlink Control，DL Control)，可以用于传输下行调度授权(DL grant)或者上行调度授权(Uplink grant)，用于指示用户设备(User Equipment，UE)资源的配置情况，第二部分为数据部分，可用于基站传输下行数据，或者用于UE根据UL grant分配的资源传输上行数据，第三部分为短时长物理上行控制信令，在该短时长物理上行控制信令的资源上，UE可以对接收到的下行数据回复确认字符或者非确认字符(Acknowl edgement/Negative Acknowledgement，ACK/NACK)，或者UE可以传输上行信道状态信息(Channel State Information，CSI)，以协助基站后续调度使用。其中，短时长物理上行控制信令部分可以被上行数据占用。
资源请求(Scheduling Request，SR)是指UE在有上行传输需求时，向基站发送的请求信令，以获得基站分配的时频域资源。当基站接收到UE的SR，基站在合适的时间发送下行控制信令，并承载分配的资源信息给UE，之后UE在基站分配的资源上进行上行传输。但是，在5G NR的子帧设计中，short PUCCH如何承载SR是一个亟待解决的问题。
发明内容
本申请实施例提供一种资源请求的发送方法、用户设备和基站，能够解决short PUCCH如何承载SR的问题。
第一方面，提供一种资源请求的发送方法，包括：用户设备UE在用于传输物理上行控制信令的资源传输第一序列承载物理上行控制信令并指示资源请求SR；或，用户设备UE在用于传输物理上行控制信令的资源使用第一子载波组传输物理上行控制信令并指示资源请求SR。其中，在采用第一序列承载物理上行控制信令时可以采用频分的方式，一部分子载波用于承载物理上行控制信令的参考信号(Demodulated  reference signal，DMRS)，另一部分子载波用于承载物理上行控制信令的上行控制信息(Uplink control information，UCI)。这里的物理上行控制信令可以为低负载的短时长物理上行控制信令(short PUCCH)。采用第一序列时就可以说明有物理上行控制信令并指示SR；或者采用码分的方式，即采用不同的子载波组指示传输物理上行控制信令时是否还有SR传输，采用第一子载波组传输物理上行控制信令并指示SR，这样，可以解决short PUCCH中如何承载SR的问题。
在一种可能的实现中，第一序列与第二序列不同，第二序列用于传输物理上行控制信令；第一子载波组与第二子载波组的子载波位置不同，第二子载波组用于传输物理上行控制信令。也就是说，采用第二序列传输物理上行控制信令时指示没有SR同时传输，第二序列仅用于传输物理上行控制信令，或者采用第二子载波组传输物理上行控制信令时指示没有SR同时传输，第二子载波组仅用于传输物理上行控制信令。
在一种可能的实现中，在用户设备UE在用于传输物理上行控制信令的资源传输第一序列承载物理上行控制信令并指示SR之前，方法还包括：UE接收基站发送的第一信令，以及接收基站发送的第二信令；其中，第一信令包括基站配置的用于传输物理上行控制信令并指示SR的第一序列，第一序列包括序列1和序列2，序列1用于承载物理上行控制信令的参考信息DMRS，序列2用于承载物理上行控制信令的上行控制信息；第二信令包括基站配置的用于传输物理上行控制信令的第二序列，第二序列包括序列3和序列4，序列3用于承载DMRS，序列4用于承载上行控制信息；其中，序列1与序列3不同，或序列2与序列4不同，序列1和序列2所属的子载波位置不同，序列3和序列4所属的子载波位置不同。也即，采用序列1和序列2在物理上行控制信令的资源上传输物理上行控制信令时指示有SR传输，采用序列3和序列4在物理上行控制信令的资源上传输物理上行控制信令时指示没有SR传输。
在一种可能的实现中，UE在用于传输物理上行控制信令的资源传输第一序列承载物理上行控制信令并指示SR包括：UE在用于传输物理上行控制信令的资源上采用序列1和序列2传输物理上行控制信令并指示SR。
在一种可能的实现中，在UE在用于传输物理上行控制信令的资源使用第一子载波组传输物理上行控制信令并指示SR之前，方法还包括：UE接收基站发送的第三信令，以及接收基站发送的第四信令；其中，第三信令包括基站配置的用于传输物理上行控制信令并指示SR的第一子载波组；第四信令包括基站配置的用于传输物理上行控制信令的第二子载波组。
另一方面，提供一种资源请求的发送方法，包括：基站向用户设备UE配置第一序列，第一序列用于承载物理上行控制信令并指示SR，以接收UE在用于传输物理上行控制信令的资源上采用第一序列传输物理上行控制信令并指示SR；或基站向UE配置第一子载波组，第一子载波组用于传输物理上行控制信令并指示SR，以接收UE在用于传输物理上行控制信令的资源上采用第一子载波组传输的物理上行控制信令并指示SR。
在一种可能的实现中，第一序列与第二序列不同，第二序列用于传输物理上行控制信令；第一子载波组与第二子载波组的子载波位置不同，第二子载波组用于传 输物理上行控制信令。
在一种可能的实现中，基站向UE配置第一序列包括：基站向UE发送第一信令，第一信令包括基站配置的用于承载物理上行控制信令并指示SR的第一序列，第一信令用于指示UE在用于传输物理上行控制信令的资源上采用第一序列传输的物理上行控制信令并指示SR，第一序列包括序列1和序列2，序列1用于承载物理上行控制信令的参考信息DMRS，序列2用于承载物理上行控制信令的上行控制信息；在基站接收到SR和物理上行控制信令之前，方法还包括：基站向UE发送第二信令，第二信令包括基站配置的用于传输物理上行控制信令并指示SR的第二序列，第二序列包括序列3和序列4，序列3用于承载DMRS，序列4用于承载上行控制信息；其中，序列1与序列3不同，或序列2与序列4不同，序列1和序列2所属的子载波位置不同，序列3和序列4所属的子载波位置不同。
在一种可能的实现中，基站向UE配置第一子载波组包括：基站向UE发送第三信令，第三信令包括基站配置的用于传输物理上行控制信令并指示SR的第一子载波组，第三信令用于指示UE在用于传输物理上行控制信令的资源上采用第一子载波组传输物理上行控制信令并指示SR；在基站接收到物理上行控制信令并指示SR之前，方法还包括：基站向UE发送第四信令，第四信令包括基站配置的用于传输物理上行控制信令的第二子载波组，第四信令用于指示UE在用于传输物理上行控制信令的资源上采用第二子载波组传输物理上行控制信令。
再一方面，提供一种资源请求的发送方法，包括：用户设备UE在子载波间存在预设间隔的子载波组成的子载波组上采用第一序列传输SR，预设间隔包括X个子载波，X为大于或等于2的正整数。该方法可以适用于传输SR的UE复用其它UE传输的short PUCCH的资源传输SR，具体可以复用short PUCCH的DMRS的资源传输SR，这是由于short PUCCH的DMRS是在每连续N+1个子载波中，有一个承载DMRS的子载波，其余N个子载波承载UCI信号，所以这里的SR复用的子载波可以理解为子载波间存在预设间隔的子载波组成的子载波组。为了区分其他UE传输SR时采用的序列以及传输short PUCCH的DMRS采用的序列，该UE采用第一序列传输SR，可以解决short PUCCH如何承载SR进行传输的问题。
在一种可能的实现中，第一序列与UE所属的一组UE中的其它UE在子载波上传输SR时采用的序列不同；子载波组包括用于传输物理上行控制信令的参考信号DMRS占用的子载波。
在一种可能的实现中，在UE在子载波间存在预设间隔的子载波组成的子载波组上采用第一序列传输SR之前，该方法还包括：UE接收基站发送的信令；其中，信令包括UE传输SR时的频域资源以及第一序列，频域资源包括子载波组。
又一方面，提供一种资源请求的发送方法，包括：基站向用户设备UE配置UE传输资源请求SR时的子载波组以及所采用的第一序列，子载波组包括子载波间存在预设间隔的子载波，预设间隔包括X个子载波，X为大于或等于2的正整数；基站接收UE在子载波组上采用第一序列传输的SR。
在一种可能的实现中，第一序列与UE所属的一组UE中的其他UE在子载波组上传输SR时采用的序列不同；子载波组包括用于传输物理上行控制信令的参考信号 DMRS占用的子载波。
在一种可能的实现中，基站向用户设备UE配置UE传输资源请求SR时的子载波组以及所采用的第一序列包括：基站向UE发送信令，信令包括UE传输SR时的频域资源以及第一序列，频域资源包括子载波组。
又一方面，提供一种资源请求的发送方法，用于传输物理上行控制信令的资源或用于传输SR的资源占用两个符号，包括第一符号和第二符号，该方法包括：第一符号上配置有第一资源请求SR资源，第二符号上存在第二SR资源,用户设备UE使用第一符号上的第一SR资源和第二符号上的第二SR资源传输SR；或第一符号上配置有第一SR资源，第二符号上存在第二SR资源,用户设备UE使用第一符号上的第一SR资源和第二符号上的第二SR资源传输物理上行控制信令并指示SR；或第一符号上配置有第一SR资源,第二符号上存在第二SR资源，用户设备UE使用第一符号上的第一SR的资源传输物理上行控制信令并指示SR，在第二符号中第一资源传输物理上行控制信令，第一资源与第二SR资源的频域资源或码域资源不同；或第一符号上配置有第一SR资源,用户设备UE使用第一符号上的第一SR的资源传输物理上行控制信令并指示SR，在第二符号中第一资源传输物理上行控制信令。该方法针对的是占用时域上的两个符号传输short PUCCH时如何承载SR进行传输的问题。可以看出，UE可以根据两个符号中预留的SR的资源传输SR，或者，UE可以在两个符号上预留的SR资源中传输物理上行控制信令并指示有SR传输，或者两个符号中的一个符号中配置有SR资源，在该预留的SR的资源上传输物理上行控制信令并指示SR，另一个符号中传输物理上行控制信令，或者两个符号中都预留有SR的资源，但是在一个符号的SR资源上传输物理上行控制信令并指示SR，另一个符号中传输物理上行控制信令。

在一种可能的实现中，UE在第一符号上第一SR资源上传输物理上行控制信令并指示SR，在第二符号上第一资源传输物理上行控制信令，则在UE传输物理上行控制信令并指示SR之前，该方法还包括：UE接收基站发送的第二信令，第二信令用于指示第一符号上配置有第一SR资源，或者，第一符号上配置有第一SR资源且第二符号上配置有第二SR资源；其中，第一符号上配置有第一SR资源且第二符号上配置有第二SR资源时，第一符号上第一SR资源的频域资源与第二符号上第二SR的资源的频域资源相同或不同。
在一种可能的实现中，第二信令还用于指示第一资源包括基站配置的资源，或第一资源与第一符号上第一SR资源的频域间隔为第一频域间隔，第一频域间隔与第二频域间隔相同，第二频域间隔为基站指示的传输物理上行控制信令的频域资源中第二符号的频域资源与第一符号的频域资源的频域间隔。

具体实施方式
为了便于理解，示例地给出了部分与本申请相关概念的说明以供参考。如下所示：
物理上行控制信道/物理上行控制信令(Physical uplink control channel，PUCCH)，用于传输参考信号(Demodulated reference signal，DMRS)、上行控制信息(Uplink control information，UCI)、应答/否定应答(Acknowledge/Negative acknowledge，ACK/NACK)等上行控制信息。
资源请求(Scheduling request，SR)，是UE在有上行传输需求时，向基站发送的请求信令，以获得基站分配的时频域资源。当基站收到UE发送的SR，会在合适 的时间发送下行控制信令，承载分配的资源信息给UE，之后UE在基站分配的资源上进行上行传输。
第一格式物理上行控制信令和第二格式物理上行控制信令，第一格式物理上行控制信令可以理解为短时长的物理上行控制信令(short PUCCH)，第二格式物理上行控制信令可以理解为长时长的物理上行控制信令(long PUCCH)，short PUCCH和long PUCCH在一个时隙中占用资源的符号数不同，long PUCCH占用资源的符号数多于short PUCCH占用资源的符号数。例如long PUCCH占用资源的符号数为4-14个，short PUCCH占用资源的符号数为1-2个。
第一格式的short PUCCH和第二格式的short PUCCH，第一格式的short PUCCH的比特信息少于第二格式的short PUCCH占用的比特信息。
SR资源，在一个时隙中分配有第一格式SR资源和第二格式SR资源，第一格式SR资源可以理解为短时长的SR的资源，第二格式SR资源可以理解为长时长的SR的资源，第一格式SR资源和第二格式SR资源在一个时隙中占用资源的符号数不同，第二格式SR资源占用的符号数多于第一格式SR资源占用的符号数，例如第二格式SR资源占用的符号数可以为4-14个，第一格式SR资源占用的符号数可以为1-2个。
物理资源块(Physical resource block，PRB)，由频域资源上连续的多个子载波组成，例如，频域资源上连续的12个子载波组成一个PRB。、
本申请实施例可以应用于在5G NR的子帧设计中，UE在一个时隙中需要传输SR时，在该时隙中如果有第二格式的物理上行控制信令或第一格式的物理上行控制信令出现，SR如何承载。
本申请的网络架构可以包括基站201和UE202，如图2所示。
基站(Base Station，BS)设备，也可称为基站，是一种部署在无线接入网用以提供无线通信功能的装置。例如在2G网络中提供基站功能的设备包括基地无线收发站(Base Transceiver Station,BTS)和基站控制器(Base Station Controller,BSC)，3G网络中提供基站功能的设备包括节点B(NodeB)和无线网络控制器(Radio Network Controller,RNC)，在4G网络中提供基站功能的设备包括演进的节点B(evolved NodeB，eNB)，在无线局域网(Wireless Local Area Networks，WLAN)中，提供基站功能的设备为接入点(Access Point，AP)。在5G通信系统中，提供基站功能的设备包括eNB、新无线节点B(New Radio NodeB,gNB)，集中单元(Centralized Unit,CU),分布式单元(Distributed Unit)和新无线控制器等。
用户设备UE是一种终端设备，可以是可移动的终端设备，也可以是不可移动的终端设备。该设备主要用于接收或者发送业务数据。用户设备可分布于网络中，在不同的网络中用户设备有不同的名称，例如：终端，移动台，用户单元，站台，蜂窝电话，个人数字助理，无线调制解调器，无线通信设备，手持设备，膝上型电脑，无绳电话，无线本地环路台等。该用户设备可以经无线接入网(radio access network，简称：RAN)(无线通信网络的接入部分)与一个或多个核心网进行通信，例如与无线接入网交换语音和/或数据。
下面针对本申请实施例要解决的技术问题，针对不同的情况以四个实施例进行说明。
实施例一
本申请实施例一针对第一格式的short PUCCH如何承载SR的情况，分别针对有预留SR的资源和没有预留SR的资源以及以频分(FDMed)还是码分(CDMed)的方式传输short PUCCH并承载或指示SR进行讨论。
1、频分的第一格式的short PUCCH承载SR
这里的频分是指第一格式的short PUCCH所在的PRB，一部分子载波用于承载参考信号(Demodulated reference signal，DMRS)的信号，另一部分子载波用于承载上行控制信息UCI的信号。
频分的第一格式的short PUCCH承载SR的实现方式，可以在以下两种情况下讨论。
a、时隙中预留有SR的资源。
当基站和UE在交互信令时，基站分配给UE一个包括时域、频域以及码域的资源，该资源周期性的分配，即每隔固定的一段时间就会向UE分配该资源，该资源为上述SR的资源。当UE需要发送上行SR时，就在每个周期内SR的资源上传输该上行SR。特别的，该SR参考short PUCCH的传输格式，即DMRS和UCI采用频分的方式传输。UCI承载信息就是资源请求的信息，或者UCI承载信息为一个值，该值由标准规定。
时隙有预留SR资源，一个时域符号内，既出现了UE传输第一格式的short PUCCH的需求，也出现了传输SR的需求，UE在SR的资源上传输第一格式的short PUCCH；当该UE只有传输第一格式的short PUCCH的需求时，UE在基站分配的传输第一格式的short PUCCH的资源上传输第一格式的short PUCCH，传输第一格式的short PUCCH的资源与SR的资源不同，两者位于不同的频域位置。
b、时隙中未预留有SR的资源。
在时隙中未预留有SR的资源，UE需传输第一格式的short PUCCH，在传输第一格式的short PUCCH的资源上，UE根据是否需要传输SR选择第一格式的short PUCCH中相应的序列进行传输。
可选的，UE确定需传输SR，UE在用于传输物理上行控制信令的资源上传输第一序列承载物理上行控制信令并指示SR，第一序列用于传输物理上行控制信令并指示SR。
一种可能的实现中，第一序列与第二序列不同，第二序列用于传输物理上行控制信令。
在UE在用于传输物理上行控制信令的资源上传输第一序列承载物理上行控制信令并指示资源请求SR之前，该方法还包括：
UE接收基站发送的第一信令，以及接收基站发送的第二信令；
其中，第一信令包括基站配置的用于同时传输物理上行控制信令并指示SR的第一序列，第一序列包括序列1和序列2，序列1用于承载物理上行控制信令的参考信息DMRS，序列2用于承载物理上行控制信令的上行控制信息UCI。
第二信令包括基站配置的用于传输物理上行控制信令的时频域资源以及第二序列，第二序列包括序列3和序列4，序列3用于承载DMRS，序列4用于承载上行控 制信息。
其中，序列1与序列3不同，序列2与序列4不同，序列1和序列2所属的子载波位置不同，序列3和序列4所属的子载波位置不同。可选的，序列1等于序列2。
于是，当UE需传输SR时，UE在用于传输物理上行控制信令的时频域资源上采用序列1和序列2传输物理上行控制信令；当UE不传输SR时，UE在用于传输短时长物理上行控制信令的时频域资源上采用序列3和序列4传输物理上行控制信令。
上述提及的物理上行控制信令是上述提及的第一格式的short PUCCH。
下面对上述时隙中未预留有SR的资源，采用一个或多个PRB频分第一格式的short PUCCH承载SR进行举例说明。
如图3所示，一个PRB内包括12个子载波，第一格式的short PUCCH中的DMRS和UCI各占用6个子载波，此时，每6个子载波上采用互相正交的长度为6的序列，记为{seq1,seq2,seq3,seq4,seq5,seq6}。传输DMRS所用的子载波上的序列和传输UCI所用的子载波上的序列组成一个序列组，只承载第一格式的short PUCCH时采用一个序列组，既承载第一格式的short PUCCH也承载SR时采用另一个序列组，两个序列组不同。在图3中，对于某个UE，只传输第一格式的short PUCCH时采用序列seq1承载UCI，采用序列seq5承载DMRS；既承载第一格式的short PUCCH也承载SR时，采用序列seq3承载UCI，采用序列seq5承载DMRS。
在接收侧，即在基站侧，基站在接收到第一格式的short PUCCH对应的符号后，对第一格式的short PUCCH进行离散傅里叶变换(Discrete Fourier Transform，DFT)，在承载DMRS对应的子载波上乘以相应的序列得到信道估计，在承载UCI对应的子载波上分别乘以各序列运算，以检测是否有SR传输。例如，若与seq1相乘的结果高于与seq3相乘的结果，基站侧确定UE只传输了第一格式的short PUCCH，若与seq3相乘的结果高于与seq1相乘的结果，基站侧确定UE传输了第一格式的short PUCCH并承载或指示SR。
按照对于图3所示的实施例，该PRB可供4个UE同时使用以传输第一格式的short PUCCH并承载或指示SR。例如令{seqi,seqx,seqy}为一个序列组，分别对应{只有DMRS传输,只有第一格式的short PUCCH传输,SR和第一格式的short PUCCH一同传输}三种情况下所用的序列。
各UE采用的序列组为：UE1{seq5,seq1,seq3}、UE2{seq2，seq4，seq6}，UE3{seq3,seq5,seq1},UE4{seq4,seq6,seq2}。
图3所示的实施例展示了一个PRB的情况，对于占用频域范围为N个PRB的第一格式的short PUCCH，上述实施例同样适用，例如N＝2,3,4等。图4为N＝2，在2个PRB上，共24个子载波，其中12个子载波分配用于承载UCI信号，另外12个子载波分配用于承载DMRS信号。这时，基站指示UE，传输第一格式的short PUCCH并指示SR时，采用seq3承载UCI，采用seq5承载DMRS。于是，当UE只传输第一格式的short PUCCH时，在UCI占用的子载波上采用seq1承载UCI信号，在DMRS占用的子载波上采用seq5承载DMRS信号。当UE传输第一格式的short PUCCH并指示SR时，UE在UCI占用的子载波上采用seq3承载UCI信号，在DMRS占用的子载波上采用seq5承载DMRS信号。可选的，图4中所示的各序列是Zad-off Chu序列。
在基站侧，基站在接收到第一格式的short PUCCH后，进行DFT，在承载DMRS对应的子载波上乘以相应的序列得到信道估计，在承载UCI对应的子载波上分别乘以各序列运算，以检测是否有SR传输。
2、码分的第一格式的short PUCCH承载SR
码分是指在第一格式的short PUCCH所在的PRB，采用某些序列组合来承载第一格式的short PUCCH。比如2比特信息，对应4种可能的情况，分配4个序列对应各种情况，此时，第一格式的short PUCCH在传输时，不再传输UCI和DMRS，仅用某个序列来承载具体信息。码分的第一格式的short PUCCH承载SR的实现方式，以预留有SR的资源和未预留有SR的资源两种情况进行说明。
a、时隙中预留有SR的资源。
在基站和UE交互信令时，基站分配给UE一个时域频域资源，该资源可周期性地发送，即每隔固定的一段时间基站就会分配该资源，该资源就为这里的SR的资源。当UE需传输SR时，在每个周期内SR的资源传输SR。可选的，该SR可参考第一格式的PUCCH的传输格式，即以码分的方式传输。
在时隙有预留SR资源，一个时域符号内，既出现了UE传输第一格式的short PUCCH的需求，也出现了传输SR的需求，UE在SR的资源上传输第一格式的short PUCCH；当该UE只有传输第一格式的short PUCCH的需求时，UE在基站分配的传输第一格式的short PUCCH的资源上传输第一格式的short PUCCH，此时，传输基站分配的传输第一格式的物理上行控制信令的资源和SR资源不同。可选的，基站指示SR资源和第一格式的short PUCCH的资源位于不同的频域位置，当只有SR需求或者既有SR需求也有第一格式的short PUCCH的传输需求时，UE在SR资源上传输；当只有第一格式的short PUCCH的传输需求，没有SR需求时，UE在第一格式的short PUCCH的资源上传输。
b、时隙中未预留有SR的资源。
当时隙中未预留有SR的资源时，当UE有传输第一格式的short PUCCH的需求时，在传输第一格式的short PUCCH的资源上，UE根据是否需要传输SR选择子载波组进行传输。
一种可能的实现中，UE在用于传输短时长物理上行控制信令的资源上使用第一子载波组传输物理上行控制信令并指示SR，第一子载波组用于传输物理上行控制信令并指示SR。
第一子载波组与第二子载波组的子载波位置不同，第二子载波组用于传输短时长物理上行控制信令。
在UE在用于传输物理上行控制信令的资源使用第一子载波组传输物理上行控制信令并指示SR之前，该方法还包括：
UE接收基站发送的第三信令，以及接收基站发送的第四信令；
其中，第三信令包括基站配置的用于传输物理上行控制信令并指示SR的第一子载波组；
第四信令包括基站配置的用于传输物理上行控制信令的第二子载波组。
举例来说，基站指示UE传输SR所用的子载波组，子载波组1承载不需要传输 SR时的物理上行控制信令，用子载波组2承载需传输SR情况下的物理上行控制信令，即，当不传输SR时，UE在用于传输物理上行控制信令的资源上使用子载波组1上传输物理上行控制信令，当传输SR时，UE在用于传输物理上行控制信令的资源上的子载波组2上传输短时长物理上行控制信令并指示SR。
上述物理上行控制信令为第一格式的short PUCCH。
下面以采用一个或多个PRB码分第一格式的short PUCCH承载SR进行说明。
一个PRB包括12个子载波，6个子载波分为子载波组1，另外6个子载波分为子载波组2。可选的，基站指示UE子载波组1和子载波组2的子载波范围，该范围包括但不限于起始位置的子载波、子载波组内各子载波间隔子载波以及各子载波组持续子载波个数等信息中的一个或多个。如图5所示，对于某个UE，若只传输第一格式的short PUCCH时采用子载波组1承载第一格式的short PUCCH，既传输第一格式的short PUCCH也传输SR时，采用子载波组2承载第一格式的short PUCCH并指示SR。
在基站侧，基站在接收到第一格式的short PUCCH的符号后，检测各子载波组上是否有能量以确定是否有SR传输。例如，若子载波组1上接收到的能量高于子载波组2上接收到的能量，基站确定UE只传输了第一格式的short PUCCH，若子载波组2上接收到的能量高于子载波组1上接收到的能量，基站确定UE传输了第一格式的short PUCCH并指示SR。
图5仅展示了一个PRB的情况下传输第一格式的short PUCCH的子载波组和传输第一格式的short PUCCH并指示SR的子载波组。对于频域范围为N个PRB的第一格式的short PUCCH，本申请也同样适用，例如N＝2,3,4等。图6所示为N＝2时的举例，在2个PRB上，共24个子载波，其中12个子载波分配用于承载UCI信号，另外12个子载波分配用于承载DMRS信号。基站指示某个UE，传输第一格式的short PUCCH并指示SR时，采用子载波组2承载。UE在传输时，当只传输第一格式的short PUCCH时，在子载波组1上传输该第一格式的short PUCCH；当传输第一格式的short PUCCH并指示SR时，在子载波组2上传输第一格式的short PUCCH并指示SR。
在基站侧，基站在接收到第一格式的short PUCCH对应的符号后，也检测各子载波组上是否有能量，判断是否有SR传输。具体实现方式可以参见上述一个PRB的情况下的实现方式。
实施例一所阐述的SR的发送方法中，介绍了UE传输第一格式的short PUCCH承载SR的方式，包括频分和码分两种方式，分别针对有预留的SR的资源和未预留有SR的资源两种情况进行了说明。
实施例二
本申请实施例二对如何复用其它UE的short PUCCH如何承载SR的情况进行说明，这里的short PUCCH可以为上述第二格式的short PUCCH，第二格式的short PUCCH的资源仅供一个UE传输，其它UE复用其中的部分资源用来传输SR，通过某一种子载波间隔的方式在一个或连续的几个PRB上传输UE对应的SR的序列。
第二格式的short PUCCH传输方式如图7所示，在每连续N+1个子载波中，有一个承载DMRS信号的子载波，其余N个子载波承载UCI信号。可选的，N＝2,3,4,5 等。由于第二格式要求，承载UCI部分的子载波仅由一个UE使用，不能复用给其他UE，因此，DMRS部分的子载波也该UE使用，其他UE不能在该UE的承载UCI部分的子载波和承载DMRS部分的子载波上传输short PUCCH信令。由于此时DMRS子载波不止一个，有额外的码分资源供其他UE使用，本申请实施例二就是复用DMRS子载波部分的码分资源供其他UE使用传输SR。
第二格式的short PUCCH所在的频域资源可能是固定的也可能是非固定的。对于固定的情况，基站广播第二格式的short PUCCH所占资源的位置给一组UE；对于非固定的情况，基站通过动态指示一组UE第二格式short PUCCH所占资源的位置。基站预先配置或者通过发送group-common PDCCH等方式指示一组UE中各UE传输SR所用的码域资源序列，以及该组UE传输SR所用的频域资源。基站指示第二格式的short PUCCH的UE在某一时域频域资源回复较大负载的short PUCCH时采用序列1承载DMRS部分。其中，序列1与基站分配给该组UE中各UE的码域资源序列不同。
这样，一种可能的实现中，UE传输SR时，UE在子载波间存在预设间隔的子载波组成的子载波组上采用第一序列传输SR，预设间隔包括X个子载波，X为大于或等于2的正整数。
这里的第一序列与UE所属的一组UE中的其它UE在子载波上传输SR时采用的序列不同。
该子载波组包括用于传输短时长物理上行控制信令的参考信号DMRS占用的子载波。
在UE在子载波间存在预设间隔的子载波组成的子载波组上采用第一序列传输SR之前，该方法还包括：
UE接收基站发送的信令；
其中，信令包括UE传输SR时的频域资源以及第一序列，频域资源包括子载波组。
上述物理上行控制信令可以为第二格式的short PUCCH。
在基站侧，基站配置一组UE传输SR的资源，该资源包括该组UE中各UE传输SR所用的第一序列，该组UE传输SR所用的频域资源。基站配置一个UE传输第二格式的short PUCCH，配置该UE在传输DMRS时采用第二序列。
其中，第二序列和各UE传输SR所用的序列不同。UE传输DMRS的频域资源和该组UE传输SR所用的频域资源相同
基站在接收到第二格式的short PUCCH时，进行DFT，在承载DMRS对应的子载波上乘以相应的序列确定是否有SR传输。
下面以一个PRB内复用其他UE第二格式的short PUCCH的资源传输SR进行说明。
这里先说明下该方案二分为两种UE，第一种UE是只传输第二格式的short PUCCH的UE，另一种是在第一种UE的DMRS子载波上，复用DMRS子载波传输SR的UE。其中，第二种UE可为一组UE，而这组UE只传输SR。第二种UE并不知道其他UE传输有第二格式的short PUCCH，只是基站指示了UE在子载波间存在预设间隔的子载波组成的子载波组上采用第一序列传输SR。
如图8所示，一个PRB内的12个子载波，其中，4个子载波承载DMRS信号，其余8个子载波承载UCI信号。基站指示一组UE中各UE传输SR时所用的序列组，该组序列与第二格式的short PUCCH上承载DMRS所用的序列不同。可选的，基站指示传输第二格式的short PUCCH的UE用序列{+1,+1,+1,+1}承载DMRS信号；基站指示UE1采用{+1,-1,+1,-1}在该第二格式short PUCCH的DMRS所占的子载波传输SR，即UE1在基站指示的子载波上采用序列{+1,-1,+1,-1}传输SR。同理，基站指示该组UE中的UE2采用{+1,+1,-1,-1}在DMRS所占子载波上传输SR，基站指示UE3采用{+1,-1,-1,+1}在DMRS所占的子载波上传输SR。
下面对于第二格式的short PUCCH占用多个PRB时，复用其它UE第二格式的short PUCCH的资源传输SR进行说明。
如图9所示，为3个PRB内的36个子载波，其中，12个子载波承载有DMRS信号，其余24个子载波承载有UCI信号。基站指示一组UE中各UE传输SR时所用的序列组，该组序列与第二格式的short PUCCH上承载DMRS所用的序列不同。可选的，基站指示传输第二格式的short PUCCH的UE用序列2承载DMRS信号；基站指示UE1采用序列1在该第二格式short PUCCH的DMRS所占的子载波组传输SR，即UE1在该子载波组上传输序列1以指示SR。可选的，第二格式的short PUCCH的DMRS信号用Zad-off Chu序列承载。可选的，图9中所示的各UE传输SR所用的各序列属于Zad-off Chu序列。
在基站侧，基站在接收到short PUCCH对应的符号时，进行DFT，在承载DMRS对应的子载波上乘以相应的序列判断是否有SR传输。
实施例三
实施例一和实施例二是考虑了short PUCCH的资源占用单符号的情况下，频域上如何承载SR。本实施例三针对占用两个符号的short PUCCH的情况如何承载SR的问题进行说明。该符号可以理解为时域符号。
在一个时隙中的两个符号用于传输物理上行控制信令，两个符号包括第一符号和第二符号的情况下，下面分别对至少一个符号内预留有SR的资源和两个符号内均未预留有SR的资源的情况分别进行说明。
1、至少一个符号内预留有SR的资源
a、两个符号中的一个符号内预留有SR的资源，另一个符号中未预留有SR的资源
基站分配一个周期性时频域资源给UE传输SR，该资源包括但不限于时隙位置、时域符号位置、码域资源等信息。当出现该UE传输两符号的short PUCCH时，所在两个符号的某一个或两个时域符号上有SR的资源出现，UE在SR的资源上传输short PUCCH；其中对于没有SR资源的时域符号，UE在基站分配的资源上传输short PUCCH。可选的，对于有跳频的两符号short PUCCH，UE可在其中一个符号的SR的资源传输short PUCCH并指示SR，在另外一个符号上跳频传输short PUCCH，以满足跳频的要求。可选的，考虑到和原有系统同存时避免干扰，时隙/子帧中倒数第二个符号配置给UE传输SR。
也即，在一个时隙中的两个符号用于传输物理上行控制信令，两个符号包括第 一符号和第二符号，第一符号上配置有第一SR资源，UE使用第一符号上的第一SR的资源传输物理上行控制信令并指示SR，在第二符号中第一资源传输物理上行控制信令，第一资源与第二SR资源的频域资源或码域资源不同。
在UE传输长时长物理上行控制信令并指示SR之前，该方法还包括：
UE接收基站发送的第二信令，第二信令用于指示在第一符号的第一SR资源上传输所述物理上行控制信令并指示SR，且在第二符号的第一资源上传输物理上行控制信令，第一符号上配置有所述第一SR资源，第二符号上未预留有第二SR资源，或者，第一符号上配置有第一SR资源且第二符号上配置有第二SR资源；
其中，第一符号上配置有第一SR资源且第二符号上配置有所述第二SR资源时，所述第一符号上第一SR资源的频域资源与第二符号上第二SR的资源的频域资源相同或不同。
b、两个符号内均预留有SR的资源
基站分配两个或多个时频域资源给UE传输SR。例如基站分配了两个时频域资源给UE传输SR，UE传输SR时，可能占用一个符号中的SR的资源传输SR，也占用两个符号中的SR的资源传输SR。
对于占用两个符号中的SR的资源传输SR时，第一符号上配置有第一资源请求SR资源，第二符号上存在第二SR资源,用户设备UE使用第一符号上的第一SR资源和第二符号上的第二SR资源传输SR；或
第一符号上配置有第一SR资源，第二符号上存在第二SR资源,用户设备UE使用第一符号上的第一SR资源和第二符号上的第二SR资源传输物理上行控制信令并指示SR。
在UE短时长物理上行控制信令并指示SR之前，该方法还包括：
UE接收基站发送的第一信令，第一信令用于指示所述UE在第一符号上第一SR资源和第二符号上第二SR资源上传输物理上行控制信令并指示SR，第一符号上第一SR资源的频域资源与第二符号上所述第二SR资源的频域资源相同或不同。
对于占用两个符号中的第一符号的SR的资源传输SR，UE在第一符号预留的SR的资源上传输短时长物理上行控制信令并指示SR，在第二符号中第一资源传输物理上行控制信令，第一资源与第二SR资源的频域资源或码域资源不同。
其中，第一符号和第二符号中均预留有SR的资源时，第一符号中预留的SR的资源中的频域资源与第二符号中预留的SR的资源中的频域资源相同或不同。
第一资源包括基站配置的资源，或第一资源与第一符号上SR的资源的频域间隔为第一频域间隔，第一频域间隔与第二频域间隔相同，第二频域间隔为基站指示的传输短时长物理上行控制信令的频域资源中第二符号的频域资源与第一符号的频域资源的频域间隔。
可选的，对于有预留SR资源的情况，当物理上行控制信令的资源大于SR所分配资源时，物理上行控制信令部分PRB位于SR的资源内，或者频域上最低或最高或者中间的PRB位于SR的资源内。
可选的，上述a和b两种情况中的物理上行控制信令为short PUCCH。
可选的，采用两符号的short PUCCH中时域靠前的符号承载SR的信息，以达到 快速反馈的目的。
还有一种可能的情况，对于有预留SR资源的情况，而没有物理上行控制信令传输时，基站还配置UE在两个符号上至少一个符号中的频域资源为SR的资源；UE在所配置的SR的资源上传输SR，UE在第一符号上的第一SR资源和第二符号上的第二SR的资源上传输SR。
这种情况下，在UE传输SR之前，该方法还包括：
UE接收基站发送的第三信令，第三信令用于指示第一符号上的第一SR资源；
其中，若第三信令用于指示第一符号上第一SR资源，则第三信令还用于指示UE根据第一符号上第一SR资源按照预设方法获取第二符号上第二SR资源。
下面对于有预留SR的资源，无跳频且占用两符号的short PUCCH承载SR的传输的情况以及有跳频的两符号的short PUCCH承载SR传输的情况分别进行举例说明。
1)对于在有预留SR的资源，无跳频且占用两符号的short PUCCH传输时，UE既要传输SR也有传输两符号的short PUCCH时，UE在两个符号上SR所在的资源上传输short PUCCH。如图10所示，两个符号中SR的资源没有跳频，即SR的资源在两符号的频域资源相同，那么在两个符号中SR的资源上传输short PUCCH并指示SR。
在基站侧，基站根据接收到的每个符号上对应频域位置的信号/能量确定是否有SR传输。
2)对于在有预留SR的资源，有跳频的两符号的short PUCCH传输时，在传输过程中，short PUCCH有跳频，以达到分集增益。此时，SR的资源仍为一种固定频域资源，例如SR的资源在两符号中的频域资源相同，仅在SR的资源上传输不能满足short PUCCH跳频传输的要求。因此，新的传输方式需要讨论。例如图11(1)和图11(2)分别表示两种SR的资源在两符号中的频域资源相同，且支持跳频的两符号short PUCCH的传输。
对于每个符号出现一个short PUCCH资源的情况，即每个符号仅有一个或连续多个PRB用于传输short PUCCH，如图11(1)所示，时域靠后的符号上short PUCCH的频域资源与时域靠前的符号上short PUCCH频域资源的间隔(gap)记为间隔1。这里列举四种可能的传输方式如图11(1a)-图11(1d)所示。在图11(1a)中，UE在时域靠前的符号上SR的资源上传输short PUCCH的第一个符号，即在该时域靠前的符号上SR的资源上传输short PUCCH并指示SR，在时域靠后的符号上传输short PUCCH第二个符号，该时域靠后的符号上short PUCCH的资源是基站配置的，即，时域靠后的符号上short PUCCH资源由基站指示。在图11(1b)中，UE在时域靠前的符号上SR的资源上传输short PUCCH的第一个符号，即在该时域靠前的符号上SR的资源上传输short PUCCH并指示SR，在时域靠后的符号上传输short PUCCH第二个符号；此时，时域靠后的符号上short PUCCH频域资源与时域靠前的符号上SR频域资源的间隔记为间隔2；间隔2的绝对值与间隔1的绝对值相同，即间隔2为基站指示的传输short PUCCH的频域资源中第二符号的频域资源与第一符号的频域资源的频域间隔。在图11(1c)中，UE在时域靠前的符号上传输short PUCCH第一个符号，在时域靠后的符号上SR资源上传输short PUCCH的第二个符号；此时，时域靠前的符号上short PUCCH资源由基站指示。在图11(1d)中，UE在时域靠前的符号上传输 short PUCCH第一个符号，在时域靠后的符号上SR资源上传输short PUCCH的第二个符号；此时，时域靠后的符号上SR频域资源与时域靠前的符号上short PUCCH频域资源的间隔记为间隔3；间隔3的绝对值与间隔1的绝对值相同，即间隔3为基站指示的传输short PUCCH的频域资源中第二符号的频域资源与第一符号的频域资源的频域间隔。
在基站侧，基站根据接收到的一个或两个符号上对应的SR的资源频域位置的信号/能量判断是否有SR传输。
对于每个符号出现两个或多个short PUCCH资源的情况，即每个符号有两个或多个单一或连续的PRB用于传输short PUCCH，如图11(2)所示，其中一个符号上一个short PUCCH频域资源与另一short PUCCH频域资源的间隔记为间隔4。这里列举四种可能的传输方式如图11(2a)-图11(2d)所示。在图11(2a)中，UE在时域靠前的符号上SR的资源上传输short PUCCH的第一个符号，在时域靠前的符号上与SR资源间隔为间隔5的频域资源上传输short PUCCH，在时域靠后的符号上传输short PUCCH第二个符号；此时，时域靠后的符号上short PUCCH资源由基站指示；间隔5的绝对值与间隔4的绝对值相同。在图11(2b)中，UE在两个符号上SR的资源上传输short PUCCH，UE在基站指示的资源上传输short PUCCH。在图11(2c)中，UE在时域靠前的符号上传输short PUCCH，在时域靠后的符号上SR的资源上传输short PUCCH，在时域靠后的符号上与SR的资源间隔为间隔6的频域资源上传输short PUCCH；此时，时域靠前的符号上short PUCCH资源由基站指示；间隔6的绝对值与间隔4的绝对值相同。在图11(2d)中，UE在时域靠前的符号上SR的资源上传输short PUCCH，在时域靠前的符号上与SR资源间隔为间隔7的频域资源上传输short PUCCH，UE在时域靠后的符号上SR资源上传输short PUCCH，在时域靠后的符号上与SR的资源间隔为间隔8的频域资源上传输short PUCCH；间隔7的绝对值与间隔4的绝对值相同，间隔8的绝对值与间隔4的绝对值相同。
在接收侧，基站根据接收到的一个或两个符号上对应SR的资源频域位置的信号/能量判断是否有SR传输。
特别的，对于基站配置了两个或多个SR的资源的情况，即SR的资源在两个符号中的频域资源不同时，如图11(3)所示，在不传输SR时，UE在基站配置的short PUCCH的资源上传输short PUCCH；如图11(3a)所示，在传输SR时，UE在基站配置的两个或多个SR的资源上传输short PUCCH并指示SR。可选的，基站配置的两个或多个short PUCCH频域资源的其中两个频域资源的间隔为间隔9，基站配置的两个或多个SR频域资源的其中两个频域资源的间隔为间隔10，间隔9的绝对值等于间隔10的绝对值。
在接收侧，基站根据接收到的一个或两个符号上对应SR资源频域位置的信号/能量判断是否有SR传输。
再一种可能的情况中，还可能存在两个符号的每个符号上配置了两个或多个SR的资源的情况，例如每个符号中的两个SR的资源的频域资源不同。如图11(4)所示。在UE不传输SR时，UE在两个符号中基站配置的short PUCCH的资源上传输short PUCCH，在UE传输SR时，UE在基站配置的每个符号的两个或多个SR的资源上传输 short PUCCH并指示SR，如图11(4a)所示。
在接收侧，基站根据接收到的一个或两个符号上对应SR资源频域位置的信号/能量判断是否有SR传输。
又一种可能的情况中，还可能存在基站在第一符号上配置了一个SR的资源，在第二符号中未配置SR的资源的情况。如图11(5)所示。在UE不传输SR时，UE在基站配置的两个符号上的short PUCCH资源上传输short PUCCH，在UE传输SR时，如图11(5a)所示，UE在第一符号上基站配置的SR资源上传输short PUCCH并指示SR，在第二符号上基站配置的short PUCCH资源上传输short PUCCH。如图11(5b)所示，在UE传输SR时，UE在第一符号上基站配置的SR的资源上传输short PUCCH并指示SR，在第二符号上基站配置的short PUCCH资源上传输short PUCCH，该第二符号上基站配置的short PUCCH资源与第一符号上的SR资源之间的频域间隔的绝对值同基站配置的short PUCCH资源在第二符号与第一符号上的频域间隔的绝对值相同。
在接收侧，基站根据接收到的一个或两个符号上对应SR资源频域位置的信号/能量判断是否有SR传输。
图12中示出的是UE在两个符号的短时长上如何传输SR但不传输short PUCCH的情况。第一种可能的情况中，如图12(1)所示，基站分配的SR的资源位于一个时隙倒数第二个符号上。当UE传输SR时，UE在倒数第二个符号上的SR的资源上传输SR，如图12(1a)。第二种可能的情况中，基站分配的SR的资源位于两个符号的最后一个符号上，如图12(2)所示。当UE传输SR时，UE在最后一个符号上的SR的资源上传输SR，如图12(2a)所示。第三种可能的情况中，基站分配的SR的资源位于两个符号的相同频域位置上，如图12(3)所示。当UE传输SR时，UE在两个符号上的SR的资源上传输SR，如图12(3a)所示。第四种可能的情况中，基站分配的SR的资源位于两个符号的不同频域位置上，如图12(4)所示。当UE传输SR时，UE在两个符号上各自的SR的资源上传输SR，如图12(4a)所示。
在基站侧，基站根据接收到的一个或两个符号上对应SR资源频域位置的信号/能量判断是否有SR传输。
2、两个符号内均未预留有SR的资源
一种可实现的方式中，对于无跳频的short PUCCH，时隙上前后两个符号上都采用上述实施例一或实施例二中一个符号上未预留SR时，SR的传输方式。
另一种可实现的方式中，对于有跳频的short PUCCH，UE传输SR时，一个时隙中的两个符号用于传输short PUCCH，两个符号包括第一符号和第二符号，UE在第一符号中的第一资源和第二符号中的第二资源上传输short PUCCH并承载或指示SR，第一资源中的频域资源范围与用于在第二符号上传输short PUCCH的频域资源范围相同，第二资源中的频域资源范围与用于在第一符号上传输short PUCCH的频域资源范围相同。
也就是说，基站在分配的第一符号上的频域资源1和第二符号上的频域资源2传输short PUCCH，此时，若此UE传输short PUCCH并指示SR，UE在第一符号上的频域资源2和第二符号上的频域资源1上传输short PUCCH并承载或指示SR。
在UE传输短时长物理上行控制信令并指示SR之前，该方法还包括：
UE接收基站发送的信令，信令用于指示UE在传输物理上行控制信令并指示SR时，第一符号中的第一资源和第二符号中的第二资源。
上述短时长物理上行控制信令为上述的说明中的short PUCCH。
在基站侧，基站根据接收到的两个符号上的信号/能量确定是否有SR传输。
实施例四
在一个时隙中，可能出现第一格式SR资源和第二格式SR资源都出现的情况，或者long PUCCH的资源和short PUCCH的资源都出现的情况。相对于short PUCCH的资源/第一格式的SR资源，long PUCCH/第二格式的SR资源覆盖的符号范围大，为4到14个符号。在功能上，long PUCCH例如为ACK/NACK等信息，覆盖范围大于short PUCCH。
基站配置SR资源的方式有以下两种：一、基站分别配置长时长的SR资源和短时长的SR资源给UE；二、基站配置某一个周期的SR资源给UE，不指定是长时长的SR资源还是短时长的SR资源。针对以上两种配置方式，在一个时隙里，可能出现某个UE既有长时长的SR资源又有短时长的SR资源，如图13所示。此时，如果在长的SR资源和短时长的SR资源上传输同一信息，可能造成能量浪费。
下面针对不同的情况分别进行说明。
1)基站为UE在一个时隙中既配置有第一格式SR资源，又有第二格式SR资源时，UE仅传输SR不需传输PUCCH时，则UE在第二格式SR资源和第一格式SR资源中的某一个资源上传输SR。可选的，基站指示UE仅传输SR时使用第二格式SR资源或第一格式SR资源，或者基站指示UE在两种资源都配置时默认在第二格式SR资源或第一格式SR资源上传输SR。
2)基站为UE在一个时隙中既配置有第一格式SR资源又有第二格式SR资源，第二格式SR资源所在的符号上，UE传输long PUCCH并承载或指示SR，且long PUCCH能够承载SR，则UE在第二格式SR资源的资源上传输＝long PUCCH并承载或指示SR；UE传输long PUCCH并承载或指示SR，且long PUCCH不能承载SR，则UE在第一格式SR资源上传输SR。

c、UE在时隙中传输short PUCCH和long PUCCH，即时隙中分配有short PUCCH的资源和long PUCCH的资源，long PUCCH不支持承载SR，short PUCCH支持承载SR，则UE在short PUCCH的资源上传输short PUCCH并承载或指示SR。
在4)的情况下，UE确定需传输SR之前，该方法还包括：UE接收基站发送的信令，信令用于指示UE时隙中存在long PUCCH的资源和short PUCCH的资源，则根据long PUCCH和short PUCCH是否支持承载SR，确定在long PUCCH的资源或short PUCCH的资源上传输SR。
