Abstract:
Systems, methodologies, and devices are described that facilitate transmitting a guard time parameter to a mobile device to facilitate rate matching data around a guard time region associated with a downlink subframe of a radio frame sequence. A base station transmits the guard time parameter via PBCH or DBCH to the mobile device. The base station rate matches data associated with PDSCH, comprising DBCH, around the guard time region, and transmits PDSCH to the mobile device. The mobile device identifies the guard time parameter and rate matches at least a portion of the information received via the PDSCH around the guard time region to facilitate enhanced reception of PDSCH. Optionally, a radio frame sequence can be structured so that a subframe immediately following a subframe containing DBCH is a downlink subframe, which can be known by the mobile device a priori or based on a downlink subframe parameter.
