Description

一种资源释放方法及装置 技术领域
本申请实施例涉及通信技术领域，尤其涉及一种资源释放方法及装置。
背景技术
传统的蜂窝网移动通信***，如长期演进LTE(Long Term Evolution)***、新无线NR(New Radio)***中，常规的上行数据传输是基于动态授权(grant based，GB)或动态调度的。对于处于连接态并且上行同步的终端来说，如果有上行数据需要发送，终端需要向基站在物理上行控制信道(physical uplink control channel，PUCCH)信道发送上行调度请求(scheduling request，SR)。基站在物理下行控制信道(physical downlink control channel，PDCCH)信道发送上行调度授权(UL-Grant)，为终端分配物理上行共享信道(physical uplink shared channal，PUSCH)资源。
传统动态调度的方式不仅信令开销大，且调度过程繁琐。为降低时延、信令开销以及终端功耗，通信***引入了半持续调度(semi-persistent scheduling，SPS)和免授权(grant-free，GF)传输技术。这两种技术的基本原理都是基站通过高层信令和/或物理层信令以半静态(semi-static)的方式为终端配置上行数据传输所使用的时频资源、以及传输参数。终端有上行数据传输需求时，不需要经历向基站发送SR或BSR、并且等待上行授权的过程，而是直接使用SPS/免授权配置的时频资源和传输参数向基站发送数据，实现数据的即来即走，从而达到降低传输时延、信令开销和终端功耗的目的。
对于免授权配置，为了提高资源利用效率，基站可能会调度资源的释放。目前资源释放方式还不是很成熟，有待优化。

以下首先对上行授权配置进行举例说明。
例如，在NR通信***中，引入了GF传输技术。NR支持两类上行免授权传输，分别是第一类配置授权(Type 1 configured grant，或configured grant Type 1)和第二类配置授权(Type 2 configured grant，或configured grant Type 2)。
其中，第一类配置授权中，网络设备通过RRC信令向终端下发配置的授权配置(configured grant configuration)信息。该配置的授权配置信息用于配置以下一种或多种传输资源或传输参数：时域资源的周期、开环功控相关参数、波形、冗余版本序列、重复次数、跳频模式、资源分配类型、混合自动重传请求(hybrid automatic repeat request，HARQ)进程数、解调用参考信号(demodulation reference symbol，DMRS)相关参数、调制编码方案表格、资源块(resource block group，RBG)组大小、时域资源、频域资源或MCS。终端接收到该配置的授权配置信息后，可立即使用所配置的传输参数在所配置的时频资源上传输PUSCH。
第二类配置授权中，采用两步的资源配置方式。首先，网络设备通过RRC信令下发配置的授权配置信息，该配置的配置信息用于配置包括以下一种或多种传输参数：时域资源的周期、开环功控相关参数、波形、冗余版本序列、重复次数、跳频模式、资源分配类型、HARQ进程数、解调用参考信号相关参数、MCS表格或资源块(resource block group，RBG)组大小。然后网络设备向终端下发CS-RNTI加扰的下行控制信息(downlink control information，DCI)。该DCI用于激活第二类配置授权的PUSCH传输。该DCI还可以配置一些在上述配置的配置信息里没有配置的参数。例如，该DCI中还可以配置以下一种或多种传输资源：时域资源、频域资源、DMRS、或MCS。终端在接收到高层RRC信令下发的传输参数时，不能立即使用该高层参数配置的资源和参数进行PUSCH传输，需要等到接收到相应的DCI激活并配置其他资源和参数后，才能进行PUSCH传输。
一个BWP上可以配置一套或多套配置授权，例如，一个BWP上可以配置一套或多套(如12套)配置授权。网络设备可以为每一套配置授权建立索引(index)或标识(ID)，并将索引或标识携带在配置的授权配置信息中下发给终端。索引或标识可以从0开始编号，也可以从1开始编号。终端可以使用其中索引或标识对应的一套配置授权进行PUSCH传输。这样能够支持多种对时延和可靠性有不同需求的业务。
以下介绍在几个可能的实施例中如何进行资源释放(release)。以释放上述第二类配置授权为例进行介绍。
网络设备向终端下发DCI，该DCI用于指示终端对第二类配置授权进行释放或去激活。该DCI的格式(fomat)为0_0。
DCI中包括多个指示域(field)，或者多个域。根据DCI格式的不同或DCI中域的不同，可以包括几种不同的指示方式，实现几种指示功能。
在一个可能的实施例中：
DCI为被CS-RNTI加扰。且DCI中新数据指示(new data indication，NDI)域设置为0。冗余版本(redundant version，RV)域设置成全0，调制编码方式(modulation and coding scheme，MCS)域和频域资源分配(frequency domain resource allocation，FDRA)域设置成全1。
该DCI只能指示释放一套第二类配置授权，即仅支持指示单独释放第二类配置授权。通过DCI所携带的用于指示第二类配置授权的索引或标识的域所确定。为便于描述，可以把DCI中用于指示第二类配置的授权的索引或标识的域称为释放域。例如，当释放域指示的值为5时：如果索引或标识从0开始编号，代表释放索引或标识为5的第二类配置的授权；如果索引或标识从1开始编号，代表释放索引或标识为6的第二类配置的授权。
在另一个可能的实施例中：
DCI为被CS-RNTI加扰。且DCI中NDI域设置为0，RV域设置成全0，MCS域和FDRA域设置成全1。
网络设备可以通过RRC信令向终端配置一个释放状态集，该释放状态集包含一个或多个状态(state)，例如最多16个状态。每个状态关联一个或多个索引或标识，每个索引或标识都对应一套第二类配置授权。DCI中还包括用于指示状态值的域，通过该用于指示状态值的域来指示一个状态。可以将DCI中用于指示状态的域称为释放域。终端根据释放域所指示的状态，确定该状态关联的一个或多个索引或标识，从而确定释放这些索引或标识对应的第二类配置的授权。
例如，当释放域指示的值为5时：如果状态值的最小值从0开始，代表释放状态值为5的状态所关联的全部第二类配置授权；如果状态值的最小值从1开始，代表释放状态值为6的状态所关联的全部第二类配置授权。可选的，当释放域指示的值没有状态与之对应时，例如释放域指示的值为3，而RRC配置的状态值为7,8,9，则可以仅释放索引或标识为3(如果索引或标识从0开始编号)或为4(如果索引或标识从1开始编号)的第二类配置授权。
以上描述了通过DCI format 0_0来指示释放第二类配置授权，但是，DCI format 0_0由于格式的限制，DCI format 0_0中没有指示服务小区的域和指示BWP的域，指示服务小区的域或称为指示载波(carrier)的域。当终端监听到DCI format 0_0时，确定DCI format0_0用于释放第二类配置的授权。终端默认释放当前服务小区的当前BWP上的第二类配置的授权。其中，当前服务小区是指终端监听到该DCI format 0_0的服务小区，当前BWP是指终端监听到该DCI format 0_0的BWP。
一个终端可能存在多个服务小区为该终端提供服务。由于某些小区没有PDCCH资源，所以只能通过其他小区的PDCCH资源上的DCI来指示资源释放。基于DCI format 0_0中没有指示服务小区的域，可以采用其它格式的DCI来指示资源释放。
例如，DCI format 0_1或DCI format 0_2中存在指示服务小区的域。网络设备可以通过存在指示服务小区的域的DCI向终端指示释放哪个服务小区上的资源配置。为方便描述，用于指示服务小区的域可以称为服务小区指示域或载波指示(carrier indicator)域。
例如，网络设备通过DCI format 0_1或DCI format 0_2向终端指示资源释放。DCI format 0_1或DCI format 0_2中的服务小区指示域所指示的服务小区，可能与终端当前服务小区不同。
网络设备可能为终端的某个服务小区配置两个上行载波，其中一个为补充上行(supplimentary UL)，这种情况下，某些格式的DCI中还可以包含用于指示上行(UL)载波或补充上行载波的指示域，为方面描述，用于指示上行(UL)载波或补充上行载波的指示域可以成为UL/SUL指示域(UL/SUL indicator)。
例如，DCI format 0_1或DCI format 0_2中包括UL/SUL指示域。网络设备通过DCI format 0_1或DCI format 0_2向终端指示资源释放时，通过UL/SUL指示域指示释放的是上行载波上的资源还是补充上行载波上的资源。
在某些格式的DCI中还可以包括用于指示BWP的指示域，为方便描述，用于指示BWP的指示域可以称为BWP指示域。网络设备可以在DCI中的BWP指示域指示释放哪个BWP上的资源配置。
例如，DCI format 0_1或DCI format 0_2中包括BWP指示域。网络设备通过DCI format 0_1或DCI format 0_2向终端指示资源释放。DCI format 0_1或DCI format 0_2中的BWP指示域所指示的BWP，可能与终端当前BWP不同。
对于终端来说，终端若接收到DCI，发现DCI指示与当前BWP不同的BWP，终端可能认为网络设备指示该终端进行BWP切换。而若网络设备实际希望终端释放所指示BWP的资源，则终端与网络设备的行为会发生不一致，导致通信错误。
基于此，本申请实施例提供一种资源释放方法，用于优化终端释放资源的流程。
如图2所示，本申请实施例提供的资源释放方法的流程如下所述。其中，任意多个步骤均可以形成本申请所要保护的方案，除该任意多个步骤之外其余步骤为可选步骤。
S201、网络设备向终端发送第一DCI，终端从网络设备接收第一DCI。
S202、终端判断第一DCI是否满足释放条件，若第一DCI满足释放条件，则执行S203。
可选的，若第一DCI不满足释放条件，且满足激活条件，则按照第一DCI的指示激活资源配置。若第一DCI不满足释放条件，且不满足激活条件，则丢弃该第一DCI。
S203、终端释放处于激活状态的BWP上的一个或多个资源配置。
下面对上述流程中的一些可选的实现方式进行详细描述。
网络设备若要向终端发送用于激活资源配置或用于释放资源配置的DCI，则网络设备在生成DCI时，用CS-RNTI加扰该DCI，并且将该DCI的NDI域置为0。本申请实施例中，将DCI中的某个域置为0是指将该域中的每个比特设置为0。将DCI中的某个域置为1是指将该域中的每个比特设置为1。网络设备可以根据调度终端激活或释放资源配置，来生成对应格式的DCI。
终端接收到第一DCI时，若确定该第一DCI被CS-RNTI加扰，且NDI域被置为0，则可以确定该第一DCI可能是用于激活资源配置或者用于释放资源配置的DCI。
可选的，本申请实施例中，第一DCI的格式可能是DCI format 0_1或DCI format 0_2，或其他格式，用于释放的资源配置为第二类配置授权。或者，上述第一DCI的格式可能是DCI format 1_1或DCI format 1_2，或其他格式，用于释放的资源配置为下行SPS资源。
进一步地，终端可以根据以下方式判断第一DCI是否满足释放条件。
情况1、第一DCI包括BWP域。网络设备在生成第一DCI时，对以下一种或多种域进行如下设置：BWP指示域置为预设值，RV域置为0，MCS域置为1，或FDRA域置为1。其中，BWP指示域的预设值例如可以是每个比特值为0、或每个比特值为1、或其他形式的特殊值。
BWP指示域置为预设值时，BWP指示域不再用于常规功能，即不再用于指示哪一个BWP，而是作为释放条件。
终端在收到第一DCI时，若确定以下一项或多项条件满足，则确定该第一DCI满足释放条件。其中，该一项或多项条件包括：第一DCI的RV域每个比特取值为0，MCS域每个比特取值为1，FDRA域每个比特取值为1，且BWP指示域为上述预设值。
当上述几个域中的一个或多个域满足条件时，终端确定第一DCI满足释放条件，或确定第一DCI通过释放验证(release validation)条件。也可以认为，当确定第一DCI的RV域每个比特取值为0，MCS域每个比特取值为1，FDRA域每个比特取值为1时，确定第一DCI通过释放验证条件。终端在确定第一DCI通过释放验证条件，并且确定BWP指示域为特殊值，则确定第一DCI满足释放条件。
终端确定第一DCI满足释放条件时，释放处于激活状态的BWP上的一个或多个资源配置。
可选的，第一DCI中还可能包括用于指示服务小区的载波指示域。该载波指示域所指示的服务小区可能与终端当前所处的服务小区相同或不同。不管是否相同，终端释放该载波指示域所指示的服务小区中，处于激活状态的BWP上的一个或多个资源配置。
可选的，第一DCI中还可能包括UL/SUL指示域，终端释放位于该UL/SUL指示域所指示的上行载波或补充上行载波上的、处于激活状态的BWP上的一个或多个资源配置。
本申请实施例中，载波指示域的相关描述也可以替换为服务小区指示域，载波指示域所指示的服务小区可以替换为服务小区指示域所指示的服务小区。终端释放该载波指示域所指示的服务小区中，处于激活状态的BWP上的一个或多个资源配置，还可以理解为，终端释放该服务小区指示域所指示的服务小区中，处于激活状态的BWP上的一个或多个资源配置。
本申请实施例中，载波指示域所指示的服务小区还可以替换为载波指示域所指示的载波。终端释放该载波指示域所指示的服务小区中，处于激活状态的BWP上的一个或多个资源配置，还可以理解为，终端释放该载波指示域所指示的载波上，处于激活状态的BWP上的一个或多个资源配置。
情况2、网络设备在生成第一DCI时，对以下一种或多种域进行如下设置：RV域置为0，MCS域置为1、或FDRA域置为1。
终端在收到第一DCI时，若确定以下一项或多项条件满足，则确定该第一DCI满足释放条件。其中，该一项或多项条件包括：第一DCI的RV域每个比特取值为0，MCS域每个比特取值为1，或FDRA域每个比特取值为1。
第一DCI还可能包括BWP指示域，终端若确定第一DCI满足释放条件，则忽略BWP指示域所指示的内容。在第一DCI包括BWP指示域时，第一DCI中BWP指示域所指示的BWP可能与当前处于激活状态的BWP不同，这种情况下，终端不会按照该BWP指示域所指示的BWP切换BWP，即终端不会将激活BWP设置成该BWP指示域所指示的BWP。也就是说，无论BWP指示域所指示的BWP是否与当前处于激活状态的BWP相同，终端只要确定第一DCI满足释放条件，则释放处于激活状态的BWP上的一个或多个资源配置。
该情况下，可以认为，BWP指示域不再用于常规功能，即不再用于指示哪一个BWP。
可选的，第一DCI中还可能包括用于指示服务小区的载波指示域。该载波指示域所指示的服务小区可能与终端当前所处的服务小区相同或不同。不管是否相同，终端释放该载 波指示域所指示的服务小区中，处于激活状态的BWP上的一个或多个资源配置。
可选的，第一DCI中还可能包括UL/SUL指示域，终端释放位于该UL/SUL指示域所指示的上行载波或补充上行载波上的、处于激活状态的BWP上的一个或多个资源配置。
情况3、第一DCI包括BWP域。网络设备在生成第一DCI时，对以下一种或多种域进行如下设置：RV域置为0，MCS域置为1，FDRA域置为1，BWP指示域所指示的BWP与处于激活态的BWP相同。
终端在收到第一DCI时，若确定以下一项或多项条件满足，则确定该第一DCI满足释放条件。其中，该一项或多项条件包括：第一DCI的RV域每个比特取值为0，MCS域每个比特取值为1，FDRA域每个比特取值为1，或BWP指示域所指示的BWP与处于激活状态的BWP相同。
终端确定第一DCI满足释放条件时，终端释放处于激活状态的BWP上的一个或多个资源配置。
可选的，第一DCI中还可能包括用于指示服务小区的载波指示域。该载波指示域所指示的服务小区可能与终端当前所处的服务小区相同或不同。不管是否相同，终端释放该载波指示域所指示的服务小区中，处于激活状态的BWP上的一个或多个资源配置。
可选的，第一DCI中还可能包括UL/SUL指示域，终端释放位于该UL/SUL指示域所指示的上行载波或补充上行载波上的、处于激活状态的BWP上的一个或多个资源配置。
存在两种可能性：网络设备在生成第一DCI时，第一DCI中BWP指示域所指示的BWP与终端处于激活态的BWP不同。或者，虽然网络设备在生成第一DCI时，第一DCI中BWP指示域所指示的BWP与终端处于激活态的BWP相同，但是终端在收到第一DCI时，解析BWP指示域得到的结果为BWP指示域所指示的BWP与终端处于激活态的BWP不同。在这两种可能性下，即使终端判定DCI被CS-RNTI加扰，NDI取值为0，且RV域置为0、MCS域置为1或FDRA域置为1中的至少一项满足，终端也会丢弃(discard)该第一DCI。或者，在这两种可能性下，终端若确定该第一DCI被CS-RNTI加扰，NDI域取值为0，第一DCI的RV域取值为0，MCS域取值为1，FDRA域取值为1，则终端进行BWP切换。切换到BWP指示域所指示的BWP，即，去激活当前BWP，激活BWP指示域所指示的BWP，或将BWP指示域所指示的BWP设置为激活BWP。
需要说明的是，若第一DCI满足释放条件包括n个条件，则该n个条件中的任意一项不满足，则第一DCI不满足释放条件。例如，第一DCI满足释放条件为：第一DCI的RV域每个比特取值为0，MCS域每个比特取值为1，FDRA域每个比特取值为1，且BWP指示域所指示的BWP与处于激活状态的BWP相同。则当BWP指示域所指示的BWP与处于激活状态的BWP不同时，认为第一DCI不满足释放条件。
情况4、第一DCI包括载波指示(carrier indicator)域。网络设备在生成第一DCI时，对以下一种或多种域进行如下设置：RV域置为0，MCS域置为1，FDRA域置为1，载波指示域所指示的服务小区与终端当前所处的服务小区不同。
本申请实施例中，终端当前所处的服务小区可以理解为，终端接收第一DCI的服务小区或接收第一DCI所在的服务小区。
若第一DCI中包括BWP指示域，则网络设备可以按照上述情况1～情况3中的任意一种情况对BWP指示域进行设置。
终端在收到第一DCI时，若确定以下一项或多项条件满足，则确定该第一DCI满足释 放条件。其中，该一项或多项条件包括：第一DCI的RV域每个比特取值为0，MCS域每个比特取值为1，FDRA域每个比特取值为1，载波指示域所指示的服务小区与终端当前所处的服务小区不同。
若第一DCI中包括BWP指示域，则终端在判断第一DCI是否满足释放条件时，还可以按照上述情况1～情况3中的任意一种情况BWP指示域进行判断。
终端确定第一DCI满足释放条件之后，释放载波指示域所指示的服务小区中，处于激活状态的BWP上的一个或多个资源配置。
可选的，第一DCI中还可能包括UL/SUL指示域，终端确定第一DCI满足释放条件之后，释放位于该UL/SUL指示域所指示的上行载波或补充上行载波上的、处于激活状态的BWP上的一个或多个资源配置。
若终端判定DCI被CS-RNTI加扰，NDI取值为0，且RV域置为0、MCS域置为1或FDRA域置为1中的至少一项满足，且载波指示域所指示的服务小区与当前终端所处的服务小区相同，则终端丢弃该第一DCI。
以上，对于判断第一DCI是否满足释放条件的几种可能实现方式描述完毕。
可选的，终端释放处于激活状态的BWP上的一个或多个资源配置，该一个或多个资源配置可以由第一DCI中的混合自动重传请求(hybrid automatic repeat request，HARQ)进程号(HARQ process number，HPN)域来指示。
上述资源配置可能是第二类配置授权(Type 2 configured grant)，也可能是SPS。当第一DCI满足释放条件时，可以认为该第一DCI是有效的释放第二类配置授权的DCI，或者认为是有效的释放SPS的DCI。终端根据DCI的格式来判断是用于释放第二类配置授权或SPS的DCI。例如，DCI format 0_1或DCI format 0_2用于释放第二类配置授权；DCI format 1_1或DCI format 1_2用于释放SPS。当第一DCI不满足释放条件，也不满足激活条件时，终端丢弃(discard)第一DCI中的全部信息。
可选的，若确定以下一项或多项条件满足，则确定该第一DCI满足激活条件：第一DCI的RV域每个比特取值为0，HPN域每个比特取值为0。如果第一DCI没有HPN域，则第一DCI的RV域每个比特取值为0满足激活条件。
