Abstract
Embodiments of the present application provide a wireless communication method and device. The method may include: a terminal device determines at least one time domain resource unit occupied by SRS transmission over an SRS resource; the terminal device determines a resource utilization mode used for transmitting the SRS on the at least one time domain resource unit; the terminal device performs, according to the determined resource utilization mode, the SRS transmission on the at least one time domain resource unit.
Claims18
A method for wireless communication, comprising:
- determining, by a terminal device, multiple time domain resource units occupied for performing Sounding Reference Signal (SRS) transmission on an SRS resource;
- determining, by the terminal device, a resource utilization scheme used for transmitting an SRS on the multiple time domain resource units;
- and
- performing, by the terminal device, the SRS transmission on the multiple time domain resource units according to the determined resource utilization scheme;
- wherein the multiple time domain resource units are Orthogonal Frequency Division Multiplexing (OFDM) symbols;
- and
- wherein the resource utilization scheme indicates whether frequency domain resource is switched on the multiple OFDM symbols, the resource utilization scheme comprising:
- when the frequency domain resource is switched on the multiple OFDM symbols, performing resource hopping on frequency domain resources in the multiple OFDM symbols;
- and
- when the frequency domain resource is not switched on the multiple OFDM symbols, performing transmission with adopting a same beam and a same frequency domain resource in the multiple OFDM symbols;
- wherein the multiple OFDM symbols are last N continuous OFDM symbols of a time slot, and a length of an OFDM symbol is determined according to a subcarrier spacing used to transmit the SRS on the SRS resource.
A terminal device, comprising a processor, a memory, and a transceiver, wherein the memory is configured to store a computer program, the transceiver is configured to communicate with another device under control of the processor, and the processor, when executing the computer program, is configured to control the terminal device to:
- determine multiple time domain resource units occupied for performing Sounding Reference Signal (SRS) transmission on an SRS resource;
- determine a resource utilization scheme used for transmitting an SRS on the multiple time domain resource units;
- and
- perform the SRS transmission on the multiple time domain resource units according to the determined resource utilization scheme;
- wherein the multiple time domain resource units are Orthogonal Frequency Division Multiplexing (OFDM) symbols;
- and
- wherein the resource utilization scheme indicates whether frequency domain resource is switched on the multiple OFDM symbols, the resource utilization scheme comprising:
- when the frequency domain resource is switched on the multiple OFDM symbols, performing resource hopping on frequency domain resources in the multiple OFDM symbols;
- and
- when the frequency domain resource is not switched on the multiple OFDM symbols, performing transmission with adopting a same beam and a same frequency domain resource in the multiple OFDM symbols;
- wherein the multiple OFDM symbols are last N continuous OFDM symbols of a time slot, and a length of an OFDM symbol is determined according to a subcarrier spacing used to transmit the SRS on the SRS resource.
