- FIG1 is a schematic diagram of a Multi-TRP transmission network topology diagram provided by related technologies.
- TRPs when a large number of TRPs are deployed at the base station, no matter where the UE is located, numerous TRPs can provide robust services for the UE; when the system load is low or the channel conditions are good, selecting one/part of the best TRP/link to serve the UE can ensure reliable transmission. At this time, shutting down other TRPs can save the base station energy consumption to a great extent. When the TRP that needs to be shut down is turned on again to ensure reliable transmission or system throughput, the dormant TRP is awakened.
- This scheme proposes a design scheme for TRP switch signaling that dynamically indicates carrier association under multiple transmission/reception point (Multi-TRP) transmission in the carrier aggregation (CA) scenario, which further reduces the energy consumption of the network and terminals in the system while ensuring high reliability and throughput.
- Multi-TRP multiple transmission/reception point
- CA carrier aggregation
- a bandwidth part (BWP) is associated with two TRPs serve one UE at the same time.
- the Multi-TRP transmission scenarios are divided into Physical Downlink Shared Channel (PDSCH) under the framework of Multiple-Downlink Control Information (m-DCI) and PDSCH transmission under the framework of Single-Downlink Control Information (S-DCI) and Ultra-reliable and Low Latency Communications (URLLC) enhancement for Multi-TRP/panel.
- PDSCH Physical Downlink Shared Channel
- m-DCI Multiple-Downlink Control Information
- S-DCI Single-Downlink Control Information
- URLLC Ultra-reliable and Low Latency Communications
- M-DCI Each PDSCH is transmitted through only one TRP, and the two TRPs independently schedule their own PDSCHs.
- the network-side device uses Radio Resource Control (RRC) to configure two control resource sets (CORESETs) corresponding to Coresetpoolindex (0 and 1) for UEs that support multiple downlink control information (M-DCI) transmission.
- RRC Radio Resource Control
- Multi-TRPs transmit their own control information on control resource sets (CORESETs) corresponding to different Coresetpoolindexes. Accordingly, the UE needs to detect the blind downlink control information (DCI) information on the CORESETs corresponding to the two Coresetpoolindexes.
- DCI blind downlink control information
- a PDSCH is scheduled through a single physical downlink control channel (PDCCH). Each layer of the PDSCH is mapped to a TRP/panel. Two different data streams of the PDSCH are sent simultaneously from two TRPs and occupy the same time-frequency resources, or one of the TRPs is selected for sending.
- PDCH physical downlink control channel
- Multi-TRP is applied in PDSCH repeated transmission.
- Two TRPs send two identical PDSCHs in time division/frequency division multiplexing.
- the two PDSCHs are scheduled by a downlink DCI.
- One code point in the transmission configuration indication (TCI) field of the DCI corresponds to two TCI states. These two TCI states correspond to two TRPs respectively.
- TCI transmission configuration indication
- a UE can be served by multiple TRPs at the same time. Although it can ensure high reliability of transmission, it leads to huge energy consumption on the base station side. As the traffic volume increases and the reliability requirements increase, the number of TRPs will tend to increase, and the number of aggregated carriers will also increase. As the number of nodes increases, the energy consumption on the base station side will also be greater.
- CC/BWPs may use sTRP or mTRP transmission. Therefore, when different CCs use single transmission point (sTRP) or mTRP transmission, dynamically turning on/off the TRP associated with the carrier and instructing the UE to update some behaviors can reduce the energy consumption of both the UE and the base station.
- the TRP on/off indication in the related art such as the TCI state indication, cannot control the UE update behavior: long reference signal period/no measurement/no PDCCH monitoring.
- the secondary cell (Scell) dormancy indication in the related art directly shuts down the entire carrier, and cannot realize the on/off of some TRPs on the carrier.
- the disclosed embodiments provide a resource indication method and device, and propose a signaling design for dynamically indicating the dynamic on/off of TRP for Multi-TRP transmission under carrier aggregation, which can save energy consumption on both the network side and the terminal side.

(1)M-DCI:每个PDSCH只通过一个TRP进行传输,两个TRP独立调度各自的PDSCH。网络侧设备利用无线资源控制(Radio Resource Control,RRC)为支持多下行控制信息(Multiple-Downlink Control Information,M-DCI)传输的UE配置了两种Coresetpoolindex(0和1)对应的控制资源集合(Control Resource Set,CORESET),Multi-TRP在不同的Coresetpoolindex对应的控制资源集(Control Resource Set,CORESET)上传输各自的控制信息。相应地,UE在两种Coresetpoolindex对应的CORESET上都需要检测盲检下行控制信息(Downlink control Information,DCI)信息。
(2)S-DCI:通过单个物理下行控制信道(Physical Downlink Control Channel,PDCCH)调度一个PDSCH,该PDSCH的每个layer映射到一个TRP/panel上去,PDSCH的两个不同的数据流从两个TRP同时发送占用相同的时频资源,或选择其中一个TRP发送。
(3)URLLC场景增强:Multi-TRP应用在PDSCH重复传输中,两个TRP发送时分/频分复用的两个相同的PDSCH,这两个PDSCH由一个下行DCI调度,其中DCI的传输配置指示(Transmission Configuration Indication,TCI)指示域中一个代码点(codepoint)对应两个TCI state,这两个TCI state分别对应两个TRP。
相关技术中,一个UE可以同时被多个TRP服务,虽然可以保证高可靠性的传输但导致了基站侧极大的能耗开销的。随着业务量增大,可靠性要求增高,TRP的个数也会趋于更多,聚合的载波个数也
趋于更多,基站侧的能耗开销也会更大。
对于mTRP场景,不同的公共载波(Common Carrier,CC)/BWP可能采用sTRP或mTRP传输,因此在不同的CC采用单传输点(sTRP)或mTRP传输时,对载波关联的TRP进行动态开/关并指示UE更新一些行为可以同时减少UE和基站的能耗,相关技术中TRP开/关指示,如TCI state指示无法控制UE更新行为:参考信号长周期/不测量/PDCCH不监听。相关技术中的辅小区(Secondary Cell,Scell)休眠(dormancy)指示是直接关闭整个载波,无法实现载波上部分TRP开/关。

在一些实施例中,在获取目标资源集合后,可以确定目标资源集合关联的目标BWP。
在一些实施例中,若目标BWP是当前激活的BWP,则可以在第一信令生效后在当前BWP(目标BWP)上进行资源切换(比如切换至目标资源集合)。
在一些实施例中,若目标BWP不是当前激活的BWP,则可以在第一信令生效后切换至目标BWP,并在目标BWP上进行资源切换(比如切换至目标资源集合)。
比如,目标资源集合关联一个目标BWP:
关联的目标BWP是当前激活BWP,则表示第一信令生效后在当前BWP上切换配置信息至目标资源集合;
关联的目标BWP是其他BWP,则表示信令生效后切换到其他BWP后并切换配置信息至目标资源集合。
在一个实施例中,RRC定义N(N>=1)个参考信号资源集合;每个配置信息组对应一个/组载波关联的一个/组TRP进入关闭状态;每个参考信号资源集合定义RS配置信息和/或广播信号配置信息和/或CORESET配置信息;每一个参考信号资源集合关联一个BWP:关联的BWP是当前激活BWP,则表示第一信令生效后在当前BWP上切换配置信息;关联的BWP是其他BWP,则表示信令生效后切换到其他BWP后并切换配置信息。

比如,第一信令触发/指示一个TRP关联的所有载波同时开或关(ON/OFF)(例如1比特指示多个载波关联的1个TRP执行ON/OFF,此时特征是与该TRP对应的所有载波同时ON/OFF);
比如,第一信令触发/指示一个TRP执行OFF操作时,该TRP关联的所有载波同时关闭(OFF);动态信令触发/指示一个TRP执行打开(ON)操作时,该TRP关联的第一载波集合执行ON,第二载波集合执行OFF操作;
比如,第一信令触发/指示一个TRP执行ON/OFF操作时,该TRP关联的第一载波集合执行ON,第二载波集合执行OFF操作。
本方案提出的动态指示一个/组载波关联的TRP开关的第一信令,在载波聚合场景下Multi-TRP传输中,当一些载波上只有一个或部分TRP服务即可保可靠性,吞吐量传输的情况下,关闭其余的TRP节省基站能耗的同时下发信令指示UE触发终端节能行为:不检测/长周期检测部分Search Space上的PDCCH和参考信号(比如SSB或CSI-RS等)测量行为更新,可以同时节省基站侧和终端侧的能耗开销。当需要关闭的TRP再次开启保证服务时,下发第一信令恢复原始的Multi-TRP传输下UE的行为,保证高可靠传输。在保证系统高可靠和高吞吐传输时,同时降低网络侧和终端的能耗开销。
本公开实施例可以应用于在Multi-TRP传输中,如果高层配置了区分TRP的CORESET,UE会一直在这些配置的CORESET上监听对应TRP的PDCCH,基站可以关闭一些TRP并下发信令指示UE不检测关闭TRP对应的Search Space,可以节省终端进行不必要的盲检功耗。
本公开实施例可以应用于使用节能RNTI加扰的DCI(DCI with CRC scrambled by PS-RNTI,DCP)机制中,DCP可以唤醒UE在当前BWP上所有搜索空间(Search Space)监听,如果UE支持MTRP传输,那么UE会在所有TRP对应的Search Space上监听。UE可以
选择一个最佳TRP/link即可保证可靠传输,这时也会存在基站侧TRP额外的能耗消耗以及UE侧检测这些TRP对应CORESET位置上的PDCCH的功耗开销。
本公开实施例中,关闭的TRP可以不发送/长周期发送参考信号(比如SSB、或CSI-RS);其中,终端无法区分Multi-TRP的CSI-RS资源配置,基站侧关闭一部分TRP时,这些TRP可以仅维持长周期/非周期的CSI-RS,本方案通过第一信令中携带关闭TRP关联的参考信号配置信息可以UE对关闭的TRP上CSI-RS测量行为更新,进一步减低UE测量CSI-RS的功耗。

考信号资源集合c2的情况下,即使第一信令不指示TRP3或TRP3的目标开关状态为关,终端也可以获知TRP3为第一目标TRP且TRP3会关闭。

关联的目标BWP是其他BWP,则表示信令生效后切换到其他BWP后并切换配置信息至目标资源集合。
在一个实施例中,RRC定义N(N>=1)个参考信号资源集合;每个配置信息组对应一个/组载波关联的一个/组TRP进入关闭状态;每个参考信号资源集合定义RS配置信息和/或广播信号配置信息和/或CORESET配置信息;每一个参考信号资源集合关联一个BWP:关联的BWP是当前激活BWP,则表示第一信令生效后在当前BWP上切换配置信息;关联的BWP是其他BWP,则表示信令生效后切换到其他BWP后并切换配置信息。

在一些实施例中,在第一信令显示指示第一目标TRP或指示第一目标TRP的载波或指示第一目标TRP的目标开关状态的情况下,由于第一目标TRP的目标开关状态对应目标资源集合,因此即使第一信令不指示目标资源集合,终端也可以获知目标资源集合。

在一个实施例中,可以基于显式信息和隐式信息联合动态指示第一目标TRP的目标开关状态和/或目标资源集合,比如一个/组载波关联的TRP动态开/关:
(1)可以采用前述任意实施例提供的第一信令的指示方式,联合指示一个/组载波关联的TRP动态开/关,通过显示信息指示目标CC(开启/关闭的TRP),通过隐式信息指示CC关联的TRP(目标CC),触发UE执行预定义参数配置组切换;
(2)可以定义TRP指示域:bitmap或codepoint方式指示TRP;
可以通过第一信令发送位置隐式指示开启/关闭的一个/组载波:在开启/关闭TRP关联的载波上或调度它的载波(CIF域指示此载波)上发送该第一信令(包括隐示信息);
其中,隐式信息指示一个/组参数(即第一目标TRP的目标开关状态和/或目标资源集合),显式信息指示关联的一个/组载波。
比如,隐示信息可以是TRP专属信息,如QCL信息和/或第一信令的信令发送位置(CORESETpoolindex/SS)隐式指示载波关联的生效/失效的(即第一目标TRP的目标开关状态和/或目标资源集合);
比如,定义载波指示域:bitmap或codepoint方式指示载波关联的生效/失效的参数(即第一目标TRP的目标开关状态和/或目标资源集合)。
本公开实施例中,当载波关联的TRP开启/关闭时,下发第一信令指示一个/组载波上开启/关闭的TRP信息(第一目标TRP的目标开关状态)和/或目标资源集合,触发网络侧设备预定义的TRP的开关状态关联与参考信号资源集合一一对应关联,UE根据第一信令更新行为,如长周期/不测量参考信号和/或广播信号和/或不检测一些CORESET上的PDCCH;
比如,第一信令触发/指示一个TRP关联的所有载波同时ON/OFF(例如1比特指示多个载波关联的1个TRP执行ON/OFF,
此时特征是与该TRP对应的所有载波同时ON/OFF);
比如,第一信令触发/指示一个TRP执行OFF操作时,该TRP关联的所有载波同时OFF;动态信令触发/指示一个TRP执行ON操作时,该TRP关联的第一载波集合执行ON,第二载波集合执行OFF操作;
比如,第一信令触发/指示一个TRP执行ON/OFF操作时,该TRP关联的第一载波集合执行ON,第二载波集合执行OFF操作。
本方案提出的动态指示一个/组载波关联的TRP开关的第一信令,在载波聚合场景下Multi-TRP传输中,当一些载波上只有一个或部分TRP服务即可保可靠性,吞吐量传输的情况下,关闭其余的TRP节省基站能耗的同时下发信令指示UE触发终端节能行为:不检测/长周期检测部分Search Space上的PDCCH和参考信号(比如SSB或CSI-RS等)测量行为更新,可以同时节省基站侧和终端侧的能耗开销。当需要关闭的TRP再次开启保证服务时,下发第一信令恢复原始的Multi-TRP传输下UE的行为,保证高可靠传输。在保证系统高可靠和高吞吐传输时,同时降低网络侧和终端的能耗开销。
本公开实施例可以应用于在Multi-TRP传输中,如果高层配置了区分TRP的CORESET,UE会一直在这些配置的CORESET上监听对应TRP的PDCCH,基站可以关闭一些TRP并下发信令指示UE不检测关闭TRP对应的Search Space,可以节省终端进行不必要的盲检功耗。
本公开实施例可以应用于DCP机制中,DCP可以唤醒UE在当前BWP上所有Search Space监听,如果UE支持MTRP传输,那么UE会在所有TRP对应的Search Space上监听。UE可以选择一个最佳TRP/link即可保证可靠传输,这时也会存在基站侧TRP额外的能耗消耗以及UE侧检测这些TRP对应CORESET位置上的PDCCH的功耗开销。
