1. A sounding reference signal (SRS) transmission method, comprising:
determining, according to at least one of configuration signaling information or a predefined rule, configuration information of respective SRS symbols in an uplink subframe; and
transmitting, according to the configuration information, the respective SRS symbols;
wherein one of the respective SRS symbols in the uplink subframe comprises at least one of a legacy SRS symbol or an additional SRS symbol;
wherein the legacy SRS symbol is located on a last symbol in the uplink subframe, and the additional SRS symbol is located on a symbol other than the last symbol in the uplink subframe,
wherein determining, according to the at least one of the configuration signaling information or the predefined rule, the configuration information of the respective SRS symbols in the uplink subframe comprises:
determining, according to the at least one of the configuration signaling information or the predefined rule, a frequency hopping manner of the legacy SRS symbol and/or a frequency hopping manner of the additional SRS symbol;
wherein the frequency hopping manner comprises:
on the legacy SRS symbol, adopting a first frequency hopping manner or a second frequency hopping manner; and
on the additional SRS symbol, adopting the second frequency hopping manner;
wherein the first frequency hopping manner is a manner of hopping among a plurality of subframes, and the second frequency hopping manner is a manner of hopping among a plurality of symbols in one subframe,
wherein determining, according to the at least one of the configuration signaling information or the predefined rule, the configuration information of the respective SRS symbols in the uplink subframe comprises: in response to determining that the second frequency hopping manner is adopted, determining an SRS frequency domain location through determining, based on a predefined manner, an SRS frequency domain location of the additional SRS symbol,
wherein the predefined manner comprises:
setting a user-specific SRS sending serial number corresponding to the legacy SRS symbol or one symbol of additional SRS symbols whose SRS frequency location is configured through the second configuration signaling information to be nSRS, and predefining a user-specific SRS sending serial number corresponding to the additional SRS symbol or additional SRS symbols other than the one symbol as nSRS+k*M, wherein k=0,1, 2, . . . , NSRS−1, NSRS is a number of time domain symbols occupied by the additional SRS symbols, and M is an integer or

OG Complex Work Unit Math
 wherein R is a repetition factor of the additional SRS symbols.
