Abstract:
Suitable hopping patterns designed to alleviate degradations of SRSs are provided herein. When a UE (12, 14, 200) transmits multiple SRS within the same time resource (e.g., slot), the UE is configured with an SRS hopping pattern (including an SRS bandwidth) based on at least a UE configuration bandwidth. In one exemplary embodiment, a node (12, 14, 200), e.g., a UE (14, 200) or a network node (12, 200) of a wireless network (10), controls the SRS configurations for SRS transmissions by the UE (14, 200) via one or more resource blocks. The SRS configuration comprises a hopping pattern and a first (e.g., hopping) bandwidth associated with the SRS transmissions. The node (12, 14, 200) determines the first bandwidth, and determines a second (e.g., configuration) bandwidth associated with a configuration of the UE (14, 200). The node (12, 14, 200) determines the SRS configuration for the UE (14, 200) responsive to the first and second bandwidths, and configures the UE (14, 200) according to the determined SRS configuration to control SRS transmissions by the UE (14, 200).
