Claims19
A method performed by a wireless device, the method comprising:
- receiving a sounding reference signal (SRS) configuration comprising an indication of a partial sounding factor specifying a size of a fractional portion of an SRS bandwidth to use for sounding and a location of the fractional portion of the SRS bandwidth to use for sounding;
- and
- transmitting SRS according to the received SRS configuration,
- wherein the location of the fractional portion of the SRS bandwidth to use for sounding varies based on a predefined hopping pattern.
A wireless device comprising processing circuitry operable to:
- receive a sounding reference signal (SRS) configuration comprising an indication of a size of a fractional portion of an SRS bandwidth and a location of the fractional portion of the SRS bandwidth to use for sounding;
- and
- transmit SRS according to the received SRS configuration,
- wherein the indication of the size of the fractional portion includes a partial sounding factor, Pf, and the indication of the location includes an integer, Pp, where Pp∈{0, 1, . . . , Pf−1).
A method performed by a network node, the method comprising:
- determining a sounding reference signal (SRS) configuration for a wireless device, the SRS configuration comprising an indication of a size of a fractional portion of an SRS bandwidth and a location of the fractional portion of the SRS bandwidth to use for sounding;
- and
- transmitting the SRS configuration to the wireless device,
- wherein the indication of the size of the fractional portion includes a partial sounding factor, Pf, and the indication of the location includes an integer, Pp, where Pp∈{0, 1, . . . , Pf−1).
A network node capable of operating as an integrated access and backhaul (IAB) donor, the network node comprising processing circuitry operable to:
- determine a sounding reference signal (SRS) configuration for a wireless device, the SRS configuration comprising an indication of a size of a fractional portion of an SRS bandwidth and a location of the fractional portion of the SRS bandwidth to use for sounding;
- and
- transmit the SRS configuration to the wireless device,
- wherein the indication of the size of the fractional portion includes a partial sounding factor, Pf, and the indication of the location includes an integer, Pp, where Pp∈{0, 1, . . . , Pf−1).
