Sparse reference signal-related signaling apparatus and methods

A processor-readable memory storing processor-executable instructions which, when executed by a processor in network equipment in a wireless communication network, cause the processor to perform a method comprising:

• communicating, with a User Equipment (UE), sparse reference signal-related signaling for a wireless channel that is associated with the multiple antenna ports,
• the sparse reference signal-related signaling being consistent with a sparse signaling pattern, the sparse signaling pattern including reference signal-related signaling associated with each of the antenna ports, and the sparse signaling pattern having been determined based on previous reference signal-related signaling previously communicated with the UE or another UE.

A method performed by a User Equipment (UE) in a wireless communication network, the method comprising:

• communicating, with network equipment in the wireless communication network, sparse reference signal-related signaling for a wireless channel that is associated with multiple antenna ports of the network equipment,
• the sparse reference signal-related signaling being consistent with a sparse signaling pattern, the sparse signaling pattern including reference signal-related signaling associated with each of the antenna ports, and the sparse signaling pattern having been determined based on previous reference signal-related signaling previously communicated with the UE or another UE.
