Method and device for positioning terminal

A method of positioning a terminal, comprising:

• transmitting, by a network side device, positioning measurement configuration information to the terminal, wherein the positioning measurement configuration information comprises configuration information on T transmission and reception points (TRPs) and on a plurality of downlink positioning reference signals of each TRP;
• receiving, by a network side device, measurement results for downlink positioning reference signals of a plurality of TRPs transmitted by the terminal, wherein the quantity of measurement results for each downlink positioning reference signal of each TRP is determined based on the positioning measurement configuration information and/or a terminal measurement capability, different measurement results correspond to different reception beams of the terminal, respectively, and at least one downlink positioning reference signal has two measurement results corresponding to at least two reception beams of the terminal respectively;
• and
• performing, by the network side device, terminal positioning based on the measurement results for the downlink positioning reference signals of the plurality of TRPs;
• wherein the terminal measurement capability comprises at least one of the following:
• the terminal supports reporting a maximum of P measurement results for a same downlink positioning reference signal;
• the terminal supports reporting a maximum of Q measurement results for a plurality of downlink positioning reference signals of a same TRP;
• or,
• the terminal supports reporting a maximum of R measurement results for a plurality of downlink positioning reference signals of a plurality of TRPs;
• wherein the determining, by the terminal based on the positioning measurement configuration information and/or the terminal measurement capability, the quantity of measurement results for the each downlink positioning reference signal of the each TRP comprises:
• in a case that downlink positioning reference signals configured by the positioning measurement configuration information are beyond the terminal measurement capability, determining, by the terminal, the quantity of measurement results for each downlink positioning reference signal of each TRP based on the following items with a priority order in the sequence listed:
• the quantity of TRPs to be measured;
• the quantity of downlink positioning reference signals to be measured;
• the quantity of measurement results for one downlink positioning reference signal at a plurality of reception beams.

A terminal, comprising a memory, a transceiver and a processor, wherein,

• the memory is configured to store a computer program;
• the transceiver is configured to send and receive data under control of the processor;
• and
• the processor is configured to read the computer program in the memory to perform following operations:
• measuring a downlink positioning reference signal of a transmission and reception point (TRP), to obtain a measurement result for the downlink positioning reference signal, wherein at least one downlink positioning reference signal is measured by using at least two reception beams to obtain at least two measurement results;
• and
• transmitting the measurement result for the downlink positioning reference signal of the TRP to a network;
• before the measuring the downlink positioning reference signal of the TRP the operations further comprise:
• receiving positioning measurement configuration information sent by the network, wherein the positioning measurement configuration information comprises configuration information on T TRPs and on a plurality of downlink positioning reference signals of each TRP;
• and
• determining, based on the positioning measurement configuration information and/or a terminal measurement capability, the quantity of measurement results for each downlink positioning reference signal of each TRP, wherein different measurement results correspond to different reception beams of the terminal, respectively, and at least one downlink positioning reference signal has at least two measurement results;
• wherein the terminal measurement capability comprises at least one of the following:
• the terminal supports reporting a maximum of P measurement results for a same downlink positioning reference signal;
• the terminal supports reporting a maximum of Q measurement results for a plurality of downlink positioning reference signals of a same TRP;
• or,
• the terminal supports reporting a maximum of R measurement results for a plurality of downlink positioning reference signals of a plurality of TRPs;
• wherein the determining, by the terminal based on the positioning measurement configuration information and/or the terminal measurement capability, the quantity of measurement results for the each downlink positioning reference signal of the each TRP comprises:
• in a case that downlink positioning reference signals configured by the positioning measurement configuration information are beyond the terminal measurement capability, determining, by the terminal, the quantity of measurement results for each downlink positioning reference signal of each TRP based on the following items with a priority order in the sequence listed:
• the quantity of TRPs to be measured;
