Description

上行免调度PUSCH的开环功率控制方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种上行免调度PUSCH的开环功率控制方法、装置及存储介质。
背景技术
随着通信技术的发展，为了保证覆盖范围，需要使用基于波束(beam)的发送和接收。当网络设备(例如基站)有多个发送接收点(Transmission Reception Point，TRP)时，可以使用多个TRP(Multi-TRP)/多面板(PANEL)为终端提供服务。网络设备多TRP/PANEL的应用主要为了改善小区边缘的覆盖，在服务区内提供更为均衡的服务质量，用不同的方式在多个TRP/PANEL间协作传输数据。从网络形态角度考虑，以大量的分布式接入点加基带集中处理的方式进行网络部署将更加有利于提供均衡的用户体验速率，并且显著的降低越区切换带来的时延和信令开销。利用多个TRP/PANEL之间的协作，从多个角度的多个波束进行信道的传输/接收，可以更好的克服各种遮挡/阻挡效应，保障链路连接的鲁棒性，适合超可靠低延时通信(Ultra Reliable Low Latency Communication，URLLC)业务提升传输质量和满足可靠性要求。
在R16研究阶段，基于下行多TRP/PANEL间的多点协作传输技术的应用，对物理下行共享信道(physical downlink shared channel，PDSCH)进行了传输增强。由于数据传输包括上下行信道的调度反馈。因此在URLLC的研究中，只对下行数据信道增强不能保证业务性能。因此在R17的研究中，继续对下行控制信道(physical downlink control channel，PDCCH)以及上行控制信道(physical uplink control channel，PUCCH)和上行共享信道(physical uplink shared channel，PUSCH)进行增强。
在通信系统中，存在有不同优先级、时延需求或者可靠性要求的数据业务，比如对时延和可靠性都有极高要求的URLLC业务，和对时延和可靠性要求相对较低的增强移动宽带(Enhanced Mobile Broadband，eMBB)业务。通常情况下URLLC会采用更短的传输时间间隔进行调度，且URLLC业务具有突发性和随机性，在资源分布上呈现出零散特性，其资源利用率较低，因此考虑和eMBB传输进行复用，以提升资源的利用率。与下行传输不同的是，某个终端在发送上行数据时并不能确定业务数据的传输资源是否与其他终端传输的不同优先级的业务有重叠。为了保证URLLC业务传输的可靠性，R16在调度下行控制信息(downlink control information，DCI)中引入了开环功率控制参数集合指示(Open-loop power control parameter set indication)来指示针对调度PUSCH的功率提升(power  boosting)指示功能，引入了新的无线资源控制(Radio Resource Control，RRC)参数：P0-PUSCH-Set，以用于指示功率控制。相关技术中，每一个探测信号(Sounding Reference Signal，SRS)资源指示(SRS Resource indication，SRI)都对应一个开环功控的P0-PUSCH-Set参数，并通过Open-loop power control parameter set indication来进行指示。
对于R17基于多TRP/PANEL的PUSCH增强中，PUSCH的传输场景会出现基于multi-TRP发送的URLLC业务，在不同的TRP上与eMBB业务发生冲突情况，即网络设备侧两个TRP接收的冲突干扰情况不同。如何对多TRP进行开环功率控制(Open-loop power control，OLPC)的功率提升(powerboosting)机制进行增强，是需要研究的课题。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例提供的上行免调度PUSCH的开环功率控制方法可应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括网络设备和终端。终端通过无线资源与网络设备相连接，并进行数据传输。其中，网络设备与终端之间基于波束进行数据传输。其中，网络设备与终端之间可以基于Multi-TRP进行PUSCH上行传输的增强。
可以理解的是，网络设备基于Multi-TRP与终端进行数据传输的TRP数量可以为一个或多个。图1所示的无线通信系统中网络设备基于TRP1和TRP2与终端1和终端2进行数据传输仅是进行示意性说明，并不引以为限。
进一步可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例无线通信系统，是一种提供无线通信功能的网络。 无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with CollisionAvoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。在本公开中，网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域(小区)内的终端进行通信。此外，当为车联网(V2X)通信系统时，网络设备还可以是车载设备。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、客户前置设备(Customer Premise Equipment，CPE)，口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal DigitalAssistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
本公开中网络设备与终端之间可以进行开环功率控制。R16在调度DCI中引入了Open-loop power control parameter set indication来指示针对调度PUSCH的power boosting指示功能，引入了新的RRC参数P0-PUSCH-Set用于指示功率控制，每一个SRI都对应一个开环功控的P0-PUSCH-Set参数，并通过开环控制参数指示域(Open-loop power control parameter set indication)来进行指示。
其中，网络设备通过高层信令p0-PUSCH-SetList-r16通知终端是否有功率控制参数指 示域。当没有配置高层参数p0-PUSCH-SetList-r16时，开环功率控制参数指示域为0比特，即开环功率控制参数指示域不存在，终端根据原Rel-15的机制从P0-PUSCH-AlphaSet获得P0。当配置有高层参数p0-PUSCH-SetList-r16时，开环功率控制参数指示域可以通过高层信令配置为1比特或者2比特，其中：
1)当DCI中存在SRI指示域时，开环功率控制参数指示域配置为1比特。
2)当DCI中不存在SRI指示域时，开环功率控制参数指示域可根据高层信令配置为1比特或者2比特。
3)针对上述DCI中存在SRI指示域的场景，若开环功率控制参数指示域信息为“0”，则依然沿用Rel-15的机制根据SRI指示从P0-PUSCH-AlphaSet获得P0。若开环功率控制参数指示域信息为“1”，则终端根据SRI指示从用于功率提升的开环参数集合P0-PUSCH-Set中获得P0。
针对DCI中不存在SRI域的场景，RAN1#99会议通过了DCI中开环功率控制的指示域可以配置为1比特或者2比特，P0-PUSCH-Set参数最多可以配置两个P0值。本公开实施例中上行PUSCH的开环功率控制方法应用的场景为终端进行通信过程中发生业务冲突进行功率控制参数调整的场景。例如，图1中，终端1进行URLLC业务和eMBB业务，终端2进行eMBB业务。本公开实施例的出发点为应用于当同时配置有eMBB和URLLC业务的终端1与配置了eMBB业务的终端2发生冲突时，终端1需三个不同的开环功率等级用于eMBB和URLLC的功率提升，分别为：1)用于eMBB的baseline P0，从P0-PUSCH-AlphaSet获取；2)higher P0，用于没有与eMBB发生冲突的URLLC业务的功率提升；3)highest P0，用于与eMBB发生冲突的URLLC PUSCH。
为了更清晰地描述终端如何根据高层参数和DCI指示来确定P0，可以参阅表1所示。表1示出了终端如何根据高层参数和DCI指示来确定P0。

相关技术中，网络设备和终端之间基于波束进行数据传输。R17中，网络设备与终端之间可以基于Multi-TRP进行PUSCH上行传输的增强。
对于基于multi-TRP的PUSCH增强方案中，PUSCH传输场景也会出现基于multi-TRP发送的URLLC业务在不同的TRP，与eMBB业务冲突的情况。其中，免调度(configured grant，CG)PUSCH传输场景，同样存在URLLC业务与eMBB终端业务冲突的情况，需要考虑相应的干扰控制。其中，免调度PUSCH也称为配置授权PUSCH。免调度PUSCH传输不同于调度的PUSCH传输，网络设备无法预测终端何时传输PUSCH，并且，在一个带宽部分(Bandwidth Part，BWP)内可以被配置多个免调度PUSCH资源，每种配置所分配的资源位置可能并不相同，一个BWP内免调度PUSCH配置最多可支持12种配置。
R17中，对于基于multi-TRP的PUSCH传输增强，主要方案是基于时分复用(Time Division Multiplexing，TDM)的多次重传。对于免调度PUSCH传输，则对应单一配置的免调度PUSCH控制传输以及可能对应多个配置的免调度PUSCH控制传输，都用于同一传输块(Transport Block，TB)面向多个TRP的协作传输。
当eMBB和URLLC业务发生冲突时，需要优先保证URLLC业务的传输可靠性，R16增强了DG PUSCH，引入了power boosting功能。对于免调度PUSCH并没有进行增强。
其中，免调度PUSCH与调度PUSCH不同，网络设备无法预测终端何时传输PUSCH，并且，一个终端在一个BWP上可以被配置一个或者多个免调度PUSCH资源，但是对于不同终端间的业务冲突处理的干扰控制需求仍然同样存在。当处于multi-TRP的传输场景下，面向不同的TRP的PUSCH传输和eMBB业务冲突情况可能并不相同，即网络设备的两个TRP接收的冲突干扰情况不同。如果对于免调度PUSCH的功率控制调整不区分TRP发送 就会导致终端浪费发送功率，加大对其他用户的干扰，造成降低系统性能的问题。因此需要对OLPC的power boosting机制进行增强。
本公开实施例提供一种上行免调度PUSCH的开环功率控制方法，网络设备配置并确定对应一个或多个TRP的开环功率提升参数，并发送指示信息，以指示单TRP独立发送或多TRP协作发送传输块TB所采用的免调度PUSCH配置的开环功率提升参数。通过本公开可以实现对单TRP独立发送或多TRP协作发送TB所采用的免调度PUSCH配置的开环功率提升参数的控制，进而可以进行干扰控制，保证通信业务的可靠性。
图2是根据一示例性实施例示出的一种上行免调度PUSCH的开环功率控制方法的流程图，如图2所示，上行免调度PUSCH的开环功率控制方法包括以下步骤。
在步骤S11中，配置并确定对应一个或多个TRP的开环功率提升参数。
在步骤S12中，发送指示信息，指示信息用于指示单TRP独立发送或多TRP协作发送TB所采用的免调度PUSCH配置的开环功率提升参数。
本公开实施例提供的上行免调度PUSCH的开环功率控制方法中，实现对单TRP独立发送或多TRP协作发送TB所采用的免调度PUSCH配置的开环功率提升参数的控制，进而可以进行干扰控制，保证通信业务的可靠性。
一种实施方式中，本公开实施例提供的上行免调度PUSCH的开环功率控制方法中，上行免调度PUSCH配置包括免调度PUSCH类型1和免调度PUSCH类型2。免调度PUSCH类型1也可以称为是配置授权类型1(Type 1)，免调度PUSCH类型2也可以称为是配置授权类型2(Type 2)。配置授权类型1(Type 1)和配置授权类型2(Type 2)支持两种免调度方案，区别在于激活的方式不同，其中：
配置授权类型1(Type 1)：由RRC提供上行授权，包括授权的激活。终端一旦正确接收到RRC配置，免调度PUSCH配置即立即生效。
配置授权类型2(Type 2)：由RRC提供传输周期，网络设备通过DCI实现资源激活和部分传输参数的配置，从而实现该授权配置的激活传输。终端接收到激活命令后，如果缓存中有数据发送，会根据预先配置的周期进行传输，如果没有数据，终端不会传输任何数据。PDCCH发送时刻即明确了激活时间。终端通过在上行发送媒体接入控制(Medium Access Control，MAC)控制信令来确认激活/去激活配置授权类型2。
一种实施方式中，本公开实施例提供的上行免调度PUSCH的开环功率控制方法中，可以基于RRC配置信息配置并确定对应一个或多个TRP的开环功率提升参数。相关技术中，RRC配置信息中并没有用于功率提升的参数，故本公开实施例中可以扩展RRC配置信息，在RRC配置信息中定义支持一个或多个TRP的开环功率提升参数。
图3是根据一示例性实施例示出的一种上行免调度PUSCH的开环功率控制方法的流程图，如图3所示，上行免调度PUSCH的开环功率控制方法包括以下步骤。
在步骤S21中，基于RRC配置信息，配置并确定一个或多个TRP的开环功率提升参数。
其中，RRC配置信息用于为单TRP方向或多个不同TRP方向发送TB所采用的免调度PUSCH配置，指示各自的开环功率提升参数。
本公开实施例提供的上行免调度PUSCH的开环功率控制方法中，可以对一个或多个免调度PUSCH配置中的每一免调度PUSCH配置进行开环功率提升参数的配置。其中，一个或多个免调度PUSCH配置为一个或多个不同TRP方向发送同一TB所采用的免调度PUSCH配置。即，RRC配置信息用于为一个或多个免调度PUSCH配置中的每一免调度PUSCH配置指示不同的开环功率提升参数。其中，RRC配置信息中配置的不同的开环功率提升参数为一个或多个TRP对应的开环功率提升参数。
本公开实施例提供的上行免调度PUSCH的开环功率控制方法中，为一个或多个免调度PUSCH配置中的每一免调度PUSCH配置指示不同的开环功率提升参数时，可以是对应单个配置的免调度PUSCH的多TRP传输，关联单个免调度PUSCH配置与功率控制参数。通过SRI实现与一组开环功率提升参数的映射，或者通过预定义实现与不同TRP的开环功率提升参数关联映射。一种实施方式中，一个或多个不同TRP方向发送TB所采用的单个免调度PUSCH配置，通过DCI中的SRI指示信息与功率控制参数组关联，并对应得到一个或多个TRP方向上的功率提升参数。或者另一种实施方式中，一个或多个不同TRP方向发送TB所采用的单个免调度PUSCH配置，基于预定义规则与不同TRP的功率控制参数关联，并对应得到一个或多个TRP方向上的功率提升参数。
本公开实施例提供的上行免调度PUSCH的开环功率控制方法中，关联单个免调度PUSCH配置与功率控制参数时可以采用如下至少一种方式：
方式一：通过SRI码点(codepoint)实现关联映射。在存在一个SRI指示域的情况下，通过SRI码点指示的、并分别对应一个或多个TRP的SRI指示信息，对应关联单个免调度PUSCH配置的一个或多个TRP的功率控制参数。
方式二：通过多个SRI指示域实现关联映射。在存在多个SRI指示域的情况下，通过对应不同TRP的每个SRI指示信息，对应关联单个免调度PUSCH配置的一个或多个TRP的功率控制参数。
本公开实施例提供的上行免调度PUSCH的开环功率控制方法中，可以对多个不同TRP方向发送TB所采用的多个免调度PUSCH配置进行功率控制参数的配置，以实现对多个 不同TRP方向发送TB所采用的多个免调度PUSCH配置中每一免调度PUSCH配置进行开环功率提升参数的配置。为一个或多个免调度PUSCH配置中的多个免调度PUSCH配置指示不同的开环功率提升参数时，可以是对应多个免调度PUSCH配置的多TRP传输，关联多个免调度PUSCH配置与功率控制参数。通过SRI实现与该TRP发送方向上的功率控制参数关联，或者通过预定义规则与TRP的功率控制参数关联。即，多个不同TRP方向发送TB所采用的多个免调度PUSCH配置，通过对应每个免调度配置的SRI指示信息与该TRP发送方向上的功率控制参数关联，或者通过预定义规则与TRP的功率控制参数关联。
本公开实施例提供的上行免调度PUSCH的开环功率控制方法中，也可以配置多个不同的功率控制参数集合，通过多个不同的功率控制参数集合与不同TRP的功率控制参数关联。即，配置不同的功率控制参数集合，并通过不同的SRI域对应分别映射用于不同TRP的发送参数。
本公开实施例提供的上行免调度PUSCH的开环功率控制方法中，基于RRC配置信息配置完成单TRP方向或多个不同TRP方向发送TB所采用的免调度PUSCH配置可进一步指示各自的开环功率提升参数。
一种实施方式中，本公开实施例可以通过DCI指示单TRP独立发送或多TRP协作发送TB所采用的免调度PUSCH配置的开环功率提升参数。
图4是根据一示例性实施例示出的一种上行免调度PUSCH的开环功率控制方法的流程图，如图4所示，上行免调度PUSCH的开环功率控制方法包括以下步骤。
在步骤S31中，通过通用分组(group-common，GC)-DCI发送指示信息。
本公开实施例中通过GC-DCI发送指示信息，可以通过GC-DCI指示用于不同TRP控制的功率提升参数。
其中，本公开实施例中通过GC-DCI发送指示信息时，GC-DCI中的指示域用来为免调度PUSCH直接指示对应不同TRP的多套功率控制参数。其中，GC-DCI中的指示域所指示的具体功率控制参数可以是网络配置或预定义的。并且，对于单配置情况，如果是激活DCI中的SRI指示域包含一个SRI指示，则为单TRP情况，否则为多TRP情况。对于多配置情况，激活DCI包含一个SRI指示，对应一个TRP情况。
本公开实施例中，通过GC-DCI指示用于不同TRP控制的功率提升参数时，网络设备可以通过在GC-DCI中定义相关指示域分别指示对应于SRI指示的面向不同TRP发送的用于多TRP的开环功率提升参数，以指示作用于该终端的所有配置发送的CG PUSCH。
其中，为描述方便，将DC-DCI中指示适用于终端的所有免调度PUSCH配置，并面 向不同TRP发送的多TRP对应的不同开环功率提升参数的信息域，称为第一信息域。第一信息域用于指示面向不同TRP发送的多TRP对应的不同开环功率提升参数，面向不同TRP发送的多TRP由DCI中SRI指示域指示。其中，该开环功率提升参数适用于多TRP协作发送TB所采用的全部免调度PUSCH配置。
本公开实施例中，通过GC-DCI指示用于不同TRP控制的功率提升参数时，若DCI中不存在SRI指示域，面向不同TRP发送的多TRP的开环功率提升参数与免调度PUSCH配置具有预定义关联指示关系。一示例中，若DCI中不存在SRI指示域，则可预定义使用的列表中的默认值，比如，使用对应TRP指示的P0功率参数列表中第一个P0值。
本公开实施例中，通过GC-DCI指示用于不同TRP控制的功率提升参数时，网络设备可以通过在GC-DCI中定义针对每个配置资源的相关指示域用来分别指示对应于SRI指示的不同TRP的用于multi-TRP的开环功率提升参数。其中，该指示仅作用于基站指示的对应CG PUSCH配置。
为描述方便，将DC-DCI中指示适用于网络设备指示的免调度PUSCH配置，并面向不同TRP发送的多TRP对应的不同开环功率提升参数的信息域，称为第二信息域。第二信息域用于指示一个或多个免调度PUSCH配置所对应的SRI指示信息中不同TRP发送方向上的PUSCH开环功率提升参数，或用于指示所有免调度PUSCH配置对应的不同TRP发送方向上的PUSCH开环功率提升参数。其中，该开环功率提升参数适用于单一免调度PUSCH配置。其中，该单一免调度PUSCH配置可以网络设备指示的免调度PUSCH配置。
本公开实施例中，通过GC-DCI指示用于不同TRP控制的功率提升参数时，若DCI中不存在SRI指示域，面向不同TRP发送的多TRP的开环功率提升参数与免调度PUSCH配置具有预定义关联指示关系。一示例中，若DCI中不存在SRI指示域，则可预定义使用的列表中的默认值，比如，使用对应TRP指示的P0功率参数列表中第一个P0值。
本公开实施例中，该GC-DCI可以配置为只为需要提升的一个或多个配置指示参数，也可以为终端配置的所有调度配置都指示参数，其中，不需要调整的无效即可。此种方式可以对应不同的GC-DCI设计。
本公开实施例提供的上行免调度PUSCH的开环功率控制方法，网络设备可以通过在GC-DCI中指示终端与其他用户发生时频资源冲突的时频资源位置，比如可能出现相互冲突的eMBB的时频资源位置。终端基于网络设备发送的指示信息，并由终端判断是否受到时频资源冲突的影响。如果终端确定了有受到时频资源冲突的影响，则终端分别进行不同TRP的功率提升操作。
本公开实施例提供的上行免调度PUSCH的开环功率控制方法，对于上行免调度 PUSCH的配置，通过高层信令和DCI命令的设计增强来实现对不同的TRP分别控制OLPC的功率提升控制，能够解决URLLC业务和eMBB业务冲突时的干扰控制，保证URLLC业务的高可靠性。
本公开实施例提供的上行免调度PUSCH的开环功率控制方法中，关联单个免调度PUSCH配置与功率控制参数时可以采用如下方式：通过SRI码点(codepoint)实现关联映射。在存在一个SRI指示域的情况下，通过SRI码点指示的、并分别对应一个或多个TRP的SRI指示信息，对应关联单个免调度PUSCH配置的一个或多个TRP的功率控制参数。通过GC-DCI指示用于不同TRP控制的功率提升参数时，网络设备可以通过在GC-DCI中定义相关指示域分别指示对应于SRI指示的面向不同TRP发送的用于多TRP的开环功率提升参数，以指示作用于该终端的所有配置发送的CG PUSCH。通过GC-DCI指示用于不同TRP控制的功率提升参数时，若DCI中不存在SRI指示域，面向不同TRP发送的多TRP的开环功率提升参数与免调度PUSCH配置具有预定义关联指示关系。一示例中，若DCI中不存在SRI指示域，则可预定义使用的列表中的默认值，比如，使用对应TRP指示的P0功率参数列表中第一个P0值。
