Embodiment Construction
[0067] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0068] The present invention aims at the problem that the base station cannot measure accurately and affects the positioning accuracy when the path loss reference signal or the spatial relationship information reference signal cannot be obtained in the existing technology, and provides an information processing method, which is applied to the terminal, such as figure 1 shown, including:
[0069] Step 11: When the first signal is not provided or configured, use the provided or configured second signal to perform the first operation;
[0070] Wherein, the first signal includes at least one of a first reference signal and a second reference signal;
[0071] The second signal includes at least one of a first reference signal, a second reference signal, and ...

The invention provides an information processing method and device and a terminal, and the information processing method comprises the steps: employing a provided or configured second signal to execute a first operation when a first signal is not provided or not configured, wherein the first signal comprises at least one of a first reference signal and a second reference signal, the second signal comprises at least one of a first reference signal, a second reference signal and a third reference signal, the first signal is different from the second signal, the first operation comprises at least one of calculating path loss and setting a spatial relationship, the first reference signal refers to a reference signal used as path loss reference, the second reference signal refers to a reference signal used as spatial relation information, and the third reference signal refers to the SSB of the serving cell for acquiring the MIB information. According to the scheme, the problem that the positioning precision is affected due to the fact that the base station cannot accurately perform measurement under the condition that the path loss reference signal or the space relation information reference signal cannot be obtained is solved.
Description
technical field [0001] The present invention relates to the technical field of terminals, in particular to an information processing method, device and terminal. Background technique [0002] Technical solutions for uplink positioning mainly include delay-based UL-TDOA (uplink time difference of arrival) positioning method and angle-based UL-AOA (uplink angle of arrival) positioning method. For the UL-TDOA delay positioning method, according to the difference in the propagation distance of the terminal relative to each base station, the relative time difference between the arrival time of the SRS-Pos (sounding reference signal for positioning) and the reference time of the base station itself (UL-RTOA, Uplink Relative Time of Arrival) to estimate the location of the terminal. For the UL-AOA angle positioning method, the position of the terminal is determined through multiple angle parameters according to the position direction of the terminal relative to the base station. ...
