receiving, by the LMF server, location response information transmitted by the serving cell, the location response information at least comprising SRS configuration determination information; and transmitting, by the LMF server, measurement request information to a transmission receive point (TRP), the measurement request information comprising the SRS configuration determination information. ## Claims ### Claim 1 A method for processing location information, which is performed by a location management function (LMF) server, the method comprising: transmitting, by the LMF server, location request information to a serving cell of a terminal device, the location request information at least comprising sounding reference signal (SRS) configuration recommendation information; wherein, the SRS configuration recommendation information is obtained by the LMF server according to the location request of the terminal device; receiving, by the LMF server, location response information transmitted by the serving cell, the location response information at least comprising SRS configuration determination information; and transmitting, by the LMF server, measurement request information to a transmission receive point (TRP), the measurement request information comprising the SRS configuration determination information; wherein, the SRS configuration determination information is determined by the serving cell, according to a configurable resource state of the serving cell and the SRS configuration recommendation information. ### Claim 2 (depends on 1) The method of claim 1, wherein the SRS configuration recommendation information comprises at least one of a recommended SRS configuration type, a recommended SRS time domain type, a recommended SRS minimum bandwidth, a recommended SRS frequency domain position, a recommended SRS period, a recommended SRS scramble identifier (ID), a recommended SRS transmission comb size, a recommended SRS cyclic shift, and a recommended SRS transmission port number. ### Claim 3 (depends on 1) The method of claim 1, wherein the SRS configuration determination information comprises at least one of an actually configured SRS configuration type, an actually configured SRS time domain type, an actually configured SRS bandwidth, an actually configured SRS frequency domain position, an actually configured SRS time domain position, an actually configured SRS period, an actually configured SRS scramble ID, an actually configured SRS transmission comb size, an actually configured SRS cyclic shift, and an actually configured SRS transmission port number. ### Claim 4 (depends on 3) The method of claim 3, wherein, in response to the actually configured SRS time domain type comprised in the SRS configuration determination information being periodic transmission, the transmitting, by the LMF server, measurement request information to a TRP comprises: transmitting, by the LMF server, the measurement request information to the TRP, so that the TRP performs SRS detection at a fixed position. ### Claim 5 (depends on 3) The method of claim 3, wherein, in response to the actually configured SRS time domain type comprised in the SRS configuration determination information being aperiodic transmission, the transmitting, by the LMF server, measurement request information to a TRP comprises: transmitting, by the LMF server, the measurement request information to the TRP, so that the TRP performs SRS detection at the time domain position of the aperiodically transmitted SRS. ### Claim 6 (depends on 3) The method of claim 3, wherein, in response to the actually configured SRS time domain type comprised in the SRS configuration determination information being semi-persistent transmission, the transmitting, by the LMF server, measurement request information to a TRP comprises: transmitting, by the LMF server, the measurement request information to the TRP; receiving, by the LMF server, semi-persistent SRS activation information transmitted by the serving cell; and transmitting, by the LMF server, the semi-persistent SRS activation information to the TRP, so that the TRP performs SRS detection at the time domain position of the semi-persistently transmitted SRS. ### Claim 7 (depends on 6) The method of claim 6, further comprising: receiving, by the LMF server, semi-persistent SRS deactivation information transmitted by the serving cell; and transmitting, by the LMF server, the semi-persistent SRS deactivation information to the TRP. ### Claim 8 (depends on 1) The method of claim 1, wherein the SRS configuration determination information is identical to the SRS configuration recommendation information, or the SRS configuration determination information is different from the SRS configuration recommendation information. ### Claim 9 (depends on 1) An apparatus for processing location information, comprising: a processor configured to perform the method for processing location information of claim 1 when executing computer programs. ### Claim 10 (depends on 1) A non-transitory computer-readable storage medium storing computer programs which, when executed by a processor, cause the processor to perform the method for processing location information of claim 1. ### Claim 11 A method for processing location information, which is performed by a serving cell of a terminal device, the method comprising: receiving, by the serving cell, location request information transmitted by an LMF server, the location request information at least comprising SRS configuration recommendation information, wherein the SRS configuration recommendation information is obtained by the LMF server according to the location request of the terminal device;
