Abstract

The invention discloses a tracking reference signal configuration method, a terminal and a network device. The method includes: when the network device is configured with an aperiodic reference signal that is quasi-co-located with a physical channel or a physical signal, according to a preset method, The aperiodic reference signal or the target physical signal associated with the aperiodic reference signal is determined as a physical channel or a quasi-co-located signal of the physical signal. In this embodiment of the present invention, when a network device configures an aperiodic reference signal for a physical channel or a physical signal, the accuracy of the physical channel or physical signal may be determined according to the aperiodic reference signal or a target physical signal associated with the aperiodic reference signal. Co-location parameters can ensure that physical channels or physical signals obtain corresponding large-scale parameters, thereby ensuring normal transmission of physical channels or physical signals.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a quasi-co-location configuration method, a terminal and a network device. Background technique [0002] In the fifth generation (5Generation, 5G) mobile communication system, in order to improve the reliability of the system, it is necessary to accurately measure the frequency offset, time offset, Doppler frequency shift, Doppler spread, and delay spread of the system. estimate. [0003] If the signals at the two antenna ports satisfy the quasi co-location (QCL) relationship, then the channel Doppler shift (Doppler shift), Doppler spread (Doppler spread), and average time experienced by the two sets of signals At least one of average delay, delay spread, and spatial Rx parameter is approximately the same, and the same reference signal may be used for large-scale parameter determination. Among them, QCL type (QCL type) may include: [0004] QCL type A, its qua...
