基站和UE物理晶振的频率是会有小小的偏差的,不可能做到完全一致,这使得UE接收到的射频载波信号会有相位上的偏差,在接收子载波的 解调符号星座图上,表现为相位上的旋转,即接收的调制符号偏离了一定的相位角度,这是由于频偏在时间上的积累造成的。这个时候,需要跟踪参考信号(tracking reference signal,TRS)来追踪其它数据信号的旋转相位。TRS是一种多周期的CSI-RS,确切的说是一个4-1端口,3个CSI-RS密度,位于连续两个时隙的NZP-CSI-RS,在一个时隙内时间上两个TRS最小间隔是4个OFDM符号,频域上间隔4个子载波。可以根据TRS来估算频率和时间上的误差。接收数据补偿这些误差,即可旋回原始发送的调制坐标位置。The frequency of the physical crystal oscillator of the base station and the UE will have a small deviation, and it is impossible to be completely consistent, which will cause the RF carrier signal received by the UE to have a phase deviation. , which manifests as a rotation in phase, that is, the received modulation symbol deviates from a certain phase angle, which is caused by the accumulation of frequency offset in time. At this time, a tracking reference signal (TRS) is required to track the rotational phase of other data signals. TRS is a multi-period CSI-RS, to be precise, a 4-1 port, 3 CSI-RS density, NZP-CSI-RS located in two consecutive time slots, two time in one time slot The minimum interval of TRS is 4 OFDM symbols, and the interval is 4 subcarriers in the frequency domain.

对于没有配置能用于测量的共享TRS/CSI-RS,UE继续采用SSB进行无线信号测量。这里无线信号测量可以包括:测量放松的无线信号测量。For the shared TRS/CSI-RS that is not configured for measurement, the UE continues to use SSB to perform radio signal measurement. Here, the wireless signal measurement may include measuring a relaxed wireless signal measurement.
以下结合上述任意实施例提供一个具体示例:A specific example is provided below in conjunction with any of the above-mentioned embodiments:

4、对于没有配置能用于测量的参考信号,UE继续依靠SSB用于测量放松。4. For reference signals that are not configured for measurement, the UE continues to rely on the SSB for measurement relaxation.
5、对于有配置测量,但是波束配置也要和idleUE跟踪的SSB的Index对应的波束一致,才生效。5. For measurement with configuration, but the beam configuration must be consistent with the beam corresponding to the Index of the SSB tracked by idleUE, it will take effect.
