Embodiment Construction

[0316] In order to solve the problem that the CPRS signal in the prior art cannot be adapted to the multi-beam transmission mode in the 5G NR system for signal transmission, in this disclosure, through the transmission process of the downlink and uplink CPRS signals, the network side and the terminal side The operation is limited, and the resource allocation and transmission of CPRS signals are completed.

[0317] During the downlink CPRS signal transmission process, the network side determines at least one carrier phase positioning reference signal CPRS for positioning the terminal, and configures the CPRS resource set and CPRS resource configuration information corresponding to the at least one CPRS signal based on a preset high-level scheduling algorithm , the CPRS resource configuration information is used to set resources for transmitting CPRS signals in the corresponding CPRS resource set, and then send the CPRS resource set and CPRS resource configuration information to ...

Abstract

The invention relates to the technical field of communication, in particular to a method and a device for transmitting carrier phase positioning reference signals, which are used for solving the problem of transmission of carrier phase positioning reference signals in a 5GNR system, and the method comprises the following steps: determining at least one CPRS signal, configuring a corresponding CPRS resource set and CPRS resource configuration information, and sending the CPRS resource set and the CPRS resource configuration information to a terminal, and after a transmission opportunity, determining a beam direction and a transmission beam corresponding to the at least one CPRS signal, performing beam forming processing on the transmission beam according to the beam direction, and further realizing transmission of the CPRS signal at the transmission opportunity based on the transmission beam after the beam forming processing. Therefore, multi-beam transmission of the CPRS signal in the 5G NR system can be realized based on the configured CPRS resource, the CPRS resource configuration information and a beam forming technology.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method and device for transmitting a carrier phase positioning reference signal. Background technique [0002] The carrier phase positioning reference signal (CPRS) is used to realize the positioning measurement of the user equipment (User Equipment, UE). The CPRS signal can be a pure sinusoidal carrier signal, so it only needs to occupy a very small bandwidth. [0003] Usually, the subcarrier spacing between the carrier frequencies configured by the network side for CPRS signals is smaller than the subcarrier spacing configured to meet the needs of data communication, and the frequency error and Doppler shift of the transceiver, as well as the UE The speed and carrier frequency determine the subcarrier spacing between the CPRS carrier frequencies. figure 1 (a) and (b) schematically illustrate that the CPRS signal can be carried out at the edge of the car...
