[0044] The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used in the above-mentioned systems and radio technologies, as well as other systems and radio technologies. The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, but these technologies can also be applied to systems other than the NR system, such as 6th Generation (6G) communication systems. th
[0045] In order to facilitate understanding of the embodiments of the present application, the following technical points are introduced first:
[0046] 1. Layer 1 or layer 2 triggered mobility.
[0047] In order to reduce the handover delay and further improve the user experience, the related art proposes a layer 1 or layer 2 triggered mobility handover technology (L1 / L2-triggered Mobility, LTM), and the general process is as shown in FIG. 1, which specifically includes the following steps:
[0048] (1) LTM preparation;
[0049] The terminal informs the network of the quality of the candidate cell through layer 3 measurement and reporting, the network selects a suitable candidate cell for LTM from it, and sends the configuration information of the candidate cell for LTM (including but not limited to Physical Cell Identifier (PCI), SSB configuration information, Physical Random Access Channel (RACH) configuration information for uplink synchronization, Transmission Configuration Indicator (TCI) state configuration information, configuration information of data channels and control channels, etc.) to the terminal side;
[0050] (2) LTM execution;
[0051] L1 measurement and reporting: the terminal measures the SSB of the current serving cell and the candidate cell according to the high-layer parameters such as LTM-Channel State Information (CSI)-ReportConfig configured by the network side, selects L cells, and selects M measurement results in each cell for reporting;
[0052] Early synchronization (Early sync):
[0053] - Downlink synchronization (DL sync): before performing L1 measurement, the terminal needs to complete coarse synchronization, align the time slot, and determine the SSB index. In addition, LTM also introduces the activation of the TCI state of the candidate cell before cell switching to complete fine synchronization in advance;
[0054] - Uplink synchronization (UL sync): for uplink asynchronous candidate cells, LTM supports uplink synchronization through the following three ways, as follows:
[0055] a) Trigger the terminal to send a preamble to the candidate cell through a physical downlink control channel (PDCCH) order before cell switching;
[0056] b) The terminal determines the TA value of the candidate cell through real-time differential (RTD) measurement and the timing advance (TA) value of the current serving cell (only for the candidate cell with RTD < cyclic prefix (CP) of the source cell);
[0057] c) The terminal sends a preamble to the target cell to obtain the TA value through the cell switching command;
[0058] Switching command: The terminal receives the cell switching signaling sent by the network side and applies the radio resource control (RRC) configuration information of the target cell; wherein, the medium access control (MAC) control element (CE) is taken as the carrier of the cell switching command, as shown in FIG. 2, and the cell switching command at least includes at least one of the following contents:
[0059] a) Configuration index of the target cell group;
[0060] b) Beam indication information: TCI state identity (id), or TCI state id and TCI-UL-State id;
[0061] c) Timing advance (TA) related information;
[0062] d) Indication information of the physical random access channel (PRACH), including SSB index, Preamble index, and Preamble mask index;
[0063] (3) LTM completion.
[0064] The terminal sends a handover completion message through a network preconfigured configured grant (CG)-physical uplink shared channel (PUSCH) or a target cell scheduled uplink grant (UL grant). When the terminal receives a downlink control information (DCI) for scheduling a new transmission and a hybrid automatic repeat request (HARQ) process ID is the same as a handover completion message, it is considered that the cell handover is successful.
[0065] 2. CSI-RS based L1 measurement and reporting.
[0066] As a reference signal for measuring beams and channel-related parameters in New Radio (NR), CSI-RS includes periodic, semi-persistent, and aperiodic time-domain characteristic resources. Among them, the periodic CSI-RS resource is configured by the network through RRC signaling, the semi-persistent CSI-RS resource is activated by MAC CE signaling, and the aperiodic CSI-RS resource is activated by DCI signaling.
[0067] In NR, only CSI-RS of a serving cell is currently supported for CSI measurement and reporting. CSI reporting and the time-domain characteristics of CSI-RS resources are similar and also include periodic reporting, semi-persistent reporting, and aperiodic reporting, as follows:
[0068] a) Periodic reporting: associated with periodic CSI-RS resources, the reporting resource is a physical uplink control channel (PUCCH) resource, which is configured by the network through RRC;
[0069] b) Semi-persistent reporting: associated with periodic or semi-persistent CSI-RS resources, the reporting resource can be a PUCCH resource or a PUSCH resource, wherein the PUCCH resource is determined by MAC CE signaling and the PUSCH resource is determined by DCI;
[0070] c) Aperiodic reporting: associated with periodic, semi-persistent, or aperiodic CSI-RS resources, the reporting resource is a PUSCH resource, wherein the PUSCH resource is determined by DCI;
[0071] The corresponding reporting measurement quantities of CSI reporting based on CSI-RS mainly include two types of beam reporting measurement quantities and CSI reporting measurement quantities, wherein the beam reporting measurement quantities include CSI-RS resource indicator (CRI)-Reference Signal Received Power (RSRP), cri-signal-to-noise and interference ratio (SINR), CRI-RSRP-index, CRI-SINR-index, i.e., beam reporting measurement results based on L1-RSRP or L1-SINR selection and Reference Signal (RS) identification; the CSI reporting measurement quantities include precoding matrix indicator (PMI), channel quality indicator (CQI), layer indication (Li), rank indicator (RI), etc.
[0072] In NR, the configuration framework of CSI measurement and reporting based on CSI-RS contains the following contents:
[0073] a) One CSI reporting setting can be associated with a maximum of 3 CSI resource settings (including: CSI resource setting for channel measurement, CSI resource setting for interference measurement (for example, CSI Intereference Measurement (CSI-IM)), and CSI resource setting for interference measurement (for example, Non-zero-power (NZP)-CSI-RS));
[0074] b) One aperiodic CSI resource setting can contain multiple CSI-RS resource sets (for example, NZP-CSI-RS resource set or CSI-IM resource set), and one periodic or semi-persistent CSI resource setting contains only one CSI-RS resource set;
[0075] c) One CSI-RS resource set can contain multiple CSI-RS resources (for example, CSI-IM or NZP-CSI-RS).
[0076] 3, CSI processing criteria.
[0077] The UE's capability of processing CSI reporting, i.e. the number of simultaneous CSI computation N CPU supported, needs to be reported to the network. If a UE supports N CPU simultaneous CSI computation means that the UE has N CPU CSI processing units for processing CSI reporting of all configured cells.
[0078] Available CPUs: In a certain Orthogonal frequency division multiplex (OFDM) symbol, if there are already L CPUs occupied for processing CSI reporting, the UE has N CPUs available for CSI reporting. CPU L CPUs. If in this OFDM symbol there are N CSI reports to start occupying CPUs, the nth=0,...,N-1 CSI report needs to occupy CPUs, it is possible that the number of available CPUs is less than the number of CPUs that N CSI reports need to occupy, then the UE does not need to update N-M low priority CSI reports, where 0≤M≤N is the maximum value that satisfies .
[0079] 4. Active RS.
[0080] In any slot, the number of active CSI-RS ports or active CSI-RS resources in the active Bandwidth Part (BWP) of the terminal cannot be more than the capability reported by the terminal.
[0081] NZP CSI-RS resources are active in the following time period:
[0082] a) For aperiodic CSI-RS, from the end of the PDCCH containing the request until the end of the PUSCH for this aperiodic CSI-RS.
[0083] b) For semi-persistent CSI-RS, from the end of the application of the activation command until the end of the application of the deactivation command.
[0084] c) For periodic CSI-RS, from the time when the periodic CSI-RS is configured by higher layer signaling until the time when the periodic CSI-RS configuration is released.
[0085] If a CSI-RS resource is associated with one or more CSI reports N times, the CSI-RS resource and the CSI-RS ports within the CSI-RS resource are counted N times.
