    摘要： A method for resource allocation. The method includes signaling a set of SRS subframes in which an SRS can be transmitted, wherein a UE not capable of aperiodic SRS transmission can be instructed to transmit periodic SRS in any of the SRS subframes. The method further includes signaling which of the SRS subframes are to be used for periodic SRS transmissions and which are to be used for aperiodic SRS transmissions, wherein a periodic SRS transmission is an SRS transmission that is transmitted by a UE in a first subframe, the first subframe being determined at least by the subframe in which the UE transmitted a previous SRS and an SRS periodicity, and wherein an aperiodic SRS transmission is an SRS transmission that is transmitted by a UE in a second subframe, the second subframe being determined at least by a transmission on a physical control channel to the UE.

    摘要： Methods and apparatus are provided to enable aperiodic sounding reference signaling including frequency hopping through the use of additional RRC configuration. The methods can require little or no additional L1 overhead to support narrowband frequency hopping for aperiodic sounding transmissions. In some embodiments, an approach is provided for extending an LTE periodic sounding reference signal methodology to include aperiodic sounding. One benefit of the proposed technique is that it enables each UE to perform aperiodic channel sounding in sounding subframes, using a frequency-hopping pattern, in which the sounding bandwidth of the UE can be narrowed appropriately to match its link capability. Additional benefits of the new approach include better resource utilization, lower signaling overhead, faster channel information update rates, and lower blocking probabilities.
