- Multi-antenna technology is a key technology in 3GPP (3rd Generation Partner Project) LTE (Long-Term Evolution) system and NR (New Radio) system; it obtains additional spatial freedom by configuring multiple antennas at communication nodes, such as base stations or UE (User Equipment). Multiple antennas use beamforming to form beams pointing in a specific direction to improve communication quality. When multiple antennas belong to multiple TRPs (Transmitter Receiver Points)/panels, additional diversity gain can be achieved by leveraging the spatial differences between different TRPs/panels.

- LTE Long-Term Evolution
- NR New Radio
- Deploying a heterogeneous network in which a UE receives downlink (DL) transmissions from a gNB but sends uplink (UL) transmissions to a gNB or non-co-located TRP/panel, is a key enhancement for improving uplink throughput. Furthermore, the TRP/panel receiving the UL can reduce or even disable DL transmissions to reduce energy consumption.
- DL downlink
- UL uplink
- the WI (Work Item) of NR MIMO Phase 5 was passed at the RAN (Radio Access Network) #102 plenary meeting.
- the RAN1 working group will at least enhance UL power control (PC) in the Rel-19 stage to support this UL/DL asymmetric deployment scenario; this includes configuring path loss offset for the UE to accurately calculate the path loss associated with the UE and TRP/panel; and supporting two closed-loop PC adjustment states of two SRS (Sounding Resource Signal) for gNB DL CSI (Channel State Information) acquisition and UL multi-TRP transmission respectively.
- PC UL power control
- the base station sends a TA (Timing Advance) adjustment indication to the UE via Medium Access Control (MAC) layer signaling.
- the UE determines the downlink timing based on the downlink signal from the base station and, combined with the TA adjustment indication sent by the base station, accurately determines the actual uplink transmission timing.
- the UE starts or restarts the Time Alignment Timer (TAT) corresponding to a Timing Advance Group (TAG), helping the MAC entity determine how long to consider the TAG associated with the serving cell to be aligned in uplink timing.
- TAT Time Alignment Timer
- TAG Timing Advance Group
- a serving cell can be configured with two TAGs, each corresponding to two TATs, to support scenarios with multiple downlink transmission time-points (TRPs).
- TRPs downlink transmission time-points

- the characteristics of the above method include: the existing base station that supports uplink and downlink asymmetric scenarios will not be configured with two CORESET Pools (Control Resource Set Pool) at the same time, and thus the two TAGs introduced for the two CORESET Pools can be applied to the uplink and downlink asymmetric scenarios, thereby reducing standard changes and facilitating implementation.
- the characteristics of the above method include: in this application, when the spatial parameters of the uplink signal transmitted by the first node are configured with a path loss offset, it means that the base station is configured with an uplink and downlink asymmetric scenario, and then configures two TAGs and two TATs to support the maintenance of two uplink timings.

- the target signaling indicating a target timing advance value
- the characteristics of the above method include: explicitly indicating TAG to ensure the accuracy of TA adjustment.

- the above method is characterized in that it includes:
- the first TAG and the second TAG are associated with a first TAT and a second TAT, respectively, and the target TAT is the TAT associated with the TAG indicated by the target identifier in the first TAT and the second TAT.
- the characteristics of the above method include: establishing a one-to-one correspondence between TAT and TAG to ensure the accuracy of uplink timing.
- the above method is characterized in that it includes:
- the first signaling indicates the first time-frequency resource; whether the first time-frequency resource includes the target timing advance value depends on the target identifier and the spatial parameters of the first signal.
- the characteristics of the above method include: redefining the wireless signal on which the TA is effective while continuing to use the number of bits of the TI in the existing TAC, thereby ensuring the accuracy of the uplink timing.

- the above method is characterized in that the first uplink TCI state of the first uplink TCI state and the second uplink TCI state is configured with a downlink path loss offset; the target identifier corresponds to the first TAG, and the spatial parameter of the first signal is the first uplink TCI state; when the downlink path loss offset is indicated to be enabled, the first time-frequency resource includes the effect of the target timing advance value; or, when the downlink path loss offset is not indicated to be enabled, the first time-frequency resource does not include the effect of the target timing advance value.
- the characteristics of the above method include: implicitly determining whether the timing advance indicated in the uplink and downlink asymmetric scenario is effective by determining whether the uplink TCI status includes a path loss offset, thereby distinguishing the timing advance values used by different uplink receiving points.

Description
本申请要求于2024年03月27日提交中国专利局、申请号为202410363510.9、申请名称为“一种被用于无线通信上行定时的节点中的方法和装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及无线通信系统中的信号传输方法和装置,尤其涉及上行定时的方法和装置。
多天线技术是3GPP(3rd Generation Partner Project,第三代合作伙伴项目)LTE(Long-Term Evolution,长期演进)系统和NR(New Radio,新无线)系统中的关键技术;通过在通信节点处,比如基站或UE(User Equipment,用户设备)处,配置多根天线来获得额外的空间自由度。多根天线通过波束赋型,形成波束指向一个特定方向来提高通信质量,当多根天线属于多个TRP(Transmitter Receiver Point,发送接收节点)/panel(天线面板)时,利用不同TRP/panel之间的空间差异,可以获得额外的分集增益;其中,部署异构网络(heterogeneous network),使UE能够从一个gNB接收下行(DownLink,DL)传输,但是向gNB或非共址(non-co-located)TRP/panel发送上行(UpLink,UL)传输,是提高上行链路吞吐量(throughput)的一个重要的增强方案;进一步的,接收UL的TRP/panel可以减少甚至关闭DL传输以减少能量消耗。
2023年12月,RAN(Radio Access Network,无线接入网)#102全会上通过了NR MIMO Phase 5的WI(Work Item,工作项目),RAN1工作组在Rel-19阶段至少通过增强UL功率控制(Power Control,PC)以支持这种UL/DL asymmetric(非对称)部署场景;其中包括为UE配置路损偏移,以便于精确计算UE与TRP/panel相关联的路损;以及支持分别用于gNB的DL CSI(Channel State Information,信道状态信息)获取和UL multi-TRP(多TRP)传输的两个SRS(Sounding Resource Signal,探测参考信号)的两个闭环PC调节状态。
在现有标准中,为避免传输干扰,保证基站服务的所有UE向基站发送的上行信号在到达基站时对齐(aligned),基站会通过(Medium Access Control,媒体接入控制)层信令向UE发送TA(Timing Advance,定时提前)调整的指示,UE根据来自基站的下行信号确定下行定时,并结合基站发送的TA调整的指示,能够精确确定实际的上行发送定时;与此同时,UE会启动或重启一个TAG(Timing Advance Group,定时提前组)所对应的TAT(TimeAlignmentTimer),进而帮助MAC实体确定多长时间认为服务小区所关联的TAG是不是上行时间一致。具备相同定时提前量并且使用同一个定时参考的小区被分在一个TAG,每个TAG包括至少一个被配置了上行链路的服务小区(serving cell)。在Release-17标准讨论中,一个服务小区可以被配置2个TAG,分别对应2个TAT,进而支持下行多个TRP的场景。
在UL/DL asymmetric场景中,UE上行传输时可能对应不同的波束/TRP/panel,不同波束/TRP/panel则可能对应不同的TA,如何在一个服务小区中支持不同的TA,以及对应的TAT的解读,是一个需要解决的问题。
针对上述问题,本申请公开了一种解决方案。需要说明的是,针对上述问题描述中,采用NR(New Radio,新空口)系统作为一个例子,本申请也同样适用于例如未来6G系统的场景,取得类似NR系统的技术效果;进一步的,虽然本申请的初衷是针对UL/DL asymmetric、蜂窝网、上行传输,多波束/TRP/panel场景,本申请也能应用其他非UL/DL asymmetric场景;进一步的,对不同场景(比如其他非UL/DL asymmetric场景,包括但不限于副链路(Sidelink)传输,下行传输,单波束/TRP/panel、RIS(Reconfigurable Intelligent Surface,可重构智能超表面)、车联网(Vehicle to Everything,V2X)、NCR(Network Control Repeater,网络控制直放站)容量增强系统、近距离通信的系统、NTN(Non Terrestrial Network,非地面网络)、IoT(Internet of Things,物联网)、URLLC(Ultra Reliable Low Latency Communication,超鲁棒低时延通信)网络等)采用统一的设计方案还有助于降低硬件复杂度和成本。在不冲突的情况下,本申请的任一节点中的实施例和实施例中的特征可以应用到任一其他节点中。在不冲突的情况下,本申请的实施例和实施例中的特征可以任意相互组合。
特别的,对本申请中的术语(Terminology)、名词、函数、变量的解释(如果未加特别说明)可以参考3GPP(the 3rd Generation Partnership Project,第三代合作伙伴计划)的技术标准(Technical Specification,TS)中的TS38系列、TS37系列中的定义。在需要的情况下,可以参考3GPP技术标准中的TS38.211,TS38.212,TS38.213,TS38.214,TS38.215,TS38.300,TS38.304,TS38.305,TS38.321,TS38.331,TS37.355,TS38.423,以辅助对本申请的理解。
