摘要:
Methods, systems, apparatus and computer program products are provided to facilitate the configuration and allocation of control information associated with transmissions of a wireless communication system. In systems that utilize multiple component carriers, cross-carrier signaling may be used to carry the control information associated with one component carrier on a different component carrier. By allowing control information messages to share their allocated search spaces, the number of decoding attempts needed to obtain control information can be kept within desirable limits while improving scheduling and resource allocation flexibility. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the disclosed subject matter. Therefore, it is to be understood that it should not be used to interpret or limit the scope or the meaning of the claims.

Systems and methodologies are described herein that facilitate efficient control decoding to facilitate management of cooperative relay operation in a wireless communication environment. As described herein, a relay node (RN) and/or another entity cooperating with a serving network node for respective users in a potentially assisted group can prune a search space of control decoding candidates corresponding to the respective users. For example, respective control decoding candidates corresponding to, e.g., common and/or user-specific search spaces, aggregation levels, control channel sizes, etc., can be eliminated from a reduced control search space based on various criteria. Further, sets of control decoding candidates corresponding to respective users not schedulable at a given time interval can be eliminated. In addition, control search space pruning can be performed in addition to or in place of increased cyclic redundancy check (CRC) protection for control information, thereby further decreasing the probability of false control detection.

摘要:
An apparatus and method for designing a relay backhaul channel in a wireless communication system are provided. At least one relay node utilized for communication with respective user devices and at least one relay backhaul channel for conducting in-band half-duplex communication with the at least one relay node are identified. The relay backhaul channel may be an FDM channel, a TDM/FDM channel, or a joint R-PDCCH/R-PDSCH channel. The relay channel is used for communicating with the at least one relay node. The supportable ranks of the R-PDSCH channel may depend on the number of resources reserved for demodulation reference signals in the R-PDCCH region.

Systems and methodologies are described that facilitate indicating feedback parameters for multiple single carrier assignments, multicarrier assignments, and/or the like according to single carrier-frequency division multiple access (SC-FDMA), relaxed SC-FDMA, etc. Feedback in relaxed SC-FDMA can be bundled by a mobile device to conserve power. In addition, a downlink assignment indicator (DAI) can be utilized to detect and indicate lost grants.
