Non-coherent millimeter-wave communication techniques

Abstract:

Wireless communication techniques that utilize a general purpose (GP) reference signal for non-coherent millimeter-wave communication are discussed. The GP reference signal may have a special structure allowing it to be flexibly used by a mobile device for multiple purposes. A base station may determine a repetition factor for a repetitive intra-symbol GP reference signal mapping based on an event that triggered transmission of the GP reference signal. The base station may also map the GP reference signal to resource elements of a symbol based, at least in part, on the determined repetition factor of the repetitive intra-symbol GP reference signal mapping. The base station may also transmit the mapped GP reference signal. A mobile device may receive the GP reference signal and modify at least one parameter of a plurality of parameters based, at least in part, on processing of the GP reference signal.
