<p>A method of resource allocation for uplink channel sounding in a wireless communication system is provided. A base station (eNB) first selects a number of sounding reference signal (SRS) parameters. The eNB then determines a deviation set for each selected SRS parameter and jointly encodes the selected number of SRS parameters using a number of signaling bits. The signaling bits are transmitted to a user equipment (UE) for uplink channel sounding. Based on system requirements, some parameter combinations are filtered out and only necessary parameter combinations are jointly encoded such that the number of signaling bits is limited to a predefined number. In one embodiment, the signaling bits are contained in downlink control information (DCI) via a physical downlink control channel (PDCCH) for triggering Aperiodic SRS (ap-SRS). By jointly encoding selected SRS parameters, the eNB can dynamically configure ap-SRS parameters and resources for each UE with high flexibility and efficiency.</p> |
