Abstract
A user equipment (UE) is disclosed. The UE includes a receiver and a processor that receive a radio resource control (RRC) signal including uplink (UL) sounding reference signal (SRS) configuration information. The UE also receives a semi-persistent scheduling (SPS) message to activate transmission of UL SRSs The UE may then transmit UL SRSs in a time and frequency pattern based on at least the UL SRS configuration information. A UE method and an eNode-B are also disclosed.
Claims18
A user equipment comprising:
- a receiver and a processor operable to receive a radio resource control (RRC) signal including uplink (UL) sounding reference signal (SRS) configuration information;
- and
- the receiver and the processor further operable to receive a semi-persistent scheduling (SPS) message to activate transmission of UL SRSs;
- and
- the processor and a transmitter operable to transmit UL SRSs in a time and frequency pattern based on at least the UL SRS configuration information.
A method for use in a user equipment, the method comprising:
- receiving, by the user equipment, a radio resource control (RRC) signal including uplink (UL) sounding reference signal (SRS) configuration information;
- receiving, by the user equipment, a semi-persistent scheduling (SPS) message to activate transmission of UL SRSs;
- and
- transmitting, by the user equipment, UL SRSs in a time and frequency pattern based on at least the UL SRS configuration information.
An evolved Node B (eNB) comprising:
- a transmitter and a processor operable to transmit a radio resource control (RRC) signal including uplink (UL) sounding reference signal (SRS) configuration information to at least one user equipment (UE);
- and
- the transmitter and the processor further operable to transmit a semi-persistent scheduling (SPS) message to the at least one UE to activate transmission of UL SRSs by the at least one UE;
- and
- the processor and a receiver operable to receive UL SRSs in a time and frequency pattern based on the UL SRS configuration information from the at least one UE.
