Abstract
Methods and apparatuses are provided for sounding reference signal (SRS) transmission. A plurality of parameter sets are received for an aperiodic SRS transmission. First downlink control information is received comprising an SRS request field with a first value indicating one of the plurality of parameter sets. Second downlink control information is received comprising an SRS request field with a second value indicating one of the plurality of parameter sets. A transmission of an aperiodic SRS is determined based on whether the first value is identical to the second value.
Claims20
A method for a user equipment (UE) to transmit a sounding reference signal (SRS), the method comprising the steps of:
- receiving a plurality of parameter sets for an aperiodic SRS transmission;
- receiving first downlink control information comprising an SRS request field with a first value indicating one of the plurality of parameter sets;
- receiving second downlink control information comprising an SRS request field with a second value indicating one of the plurality of parameter sets;
- and
- determining a transmission of an aperiodic SRS based on whether the first value is identical to the second value.
A method for a base station (BS) to receive a sounding reference signal (SRS), the method comprising the steps of:
- transmitting a plurality of parameter sets for an aperiodic SRS transmission;
- transmitting first downlink control information comprising an SRS request field with a first value indicating one of the plurality of parameter sets;
- transmitting second downlink control information comprising an SRS request field with a second value indicating one of the plurality of parameter sets;
- and
- determining a reception of an aperiodic SRS based on whether the first value is identical to the second value.
A user equipment (UE) apparatus for transmitting a sounding reference signal (SRS), the UE apparatus comprising:
- a receiver for receiving a plurality of parameter sets for an aperiodic SRS transmission, for receiving first downlink control information comprising an SRS request field with a first value indicating one of the plurality of parameter sets, and for receiving second downlink control information comprising an SRS request field with a second value indicating one of the plurality of parameter sets;
- and
- a transmitter for determining a transmission of an aperiodic SRS based on whether the first value is identical to the second value.
A base station (BS) apparatus for receiving a sounding reference signal (SRS), the BS apparatus comprising:
- a transmitter for transmitting a plurality of parameter sets for an aperiodic SRS transmission, for transmitting first downlink control information comprising an SRS request field with a first value indicating one of the plurality of parameter sets, and for transmitting second downlink control information comprising an SRS request field with a second value indicating one of the plurality of parameter sets;
- and
- a receiver for determining a reception of an aperiodic SRS based on whether the first value is identical to the second value.
