摘要： A system and method for synchronous spectrum sharing for a dedicated network in a wireless communication system based on orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) signaling is disclosed. The system and method includes detecting a frame of a broadcast waveform and extracting idle spectrum information associated with the dedicated subchannel to the secondary user node. The system allows transmitting data from the secondary user node in unused symbol slots identified in the idle spectrum information thereby making efficient use of unused or idle spectrum. Accordingly, secondary users of the wireless communication system can dynamically form ad-hoc mesh network communications in fixed or mobile scenarios.

摘要： Systems, apparatus and methods can be implemented for performing random access in carrier aggregation. A user equipment (UE) can transmit a random access preamble to a secondary access device of a second carrier, where the UE is served by both a primary access device and the secondary access device, and the UE is configured to attempt a total number of blind decoding attempts for decoding physical downlink control channel candidates of a UE-specific search space of the second carrier. The UE can perform a first blind decoding of first PDCCH candidates of the common search space of the second carrier, and perform a second blind decoding of second PDCCH candidates of the UE specific search space of the second carrier. A number of blind decoding attempts for the first and second blind decodings is less than or equal to the configured total number of blind decoding attempts.
