摘要:
Methods, apparatuses, and computer program products are disclosed for facilitating indicating and detecting control region sizes. A multi-carrier communication between a wireless terminal and a base station is facilitated by a first carrier having a first control region size and a second carrier having a second control region size. Embodiments are disclosed in which control region sizes are ascertained from a control signal, wherein the control is generated by either scrambling an aspect of the control signal based on the second control region size, or relating the second control region size with the first control region size. Other disclosed embodiments for ascertaining control region sizes include a reverse interleaver embodiment, wherein a set of modulation symbols is mapped beginning from a last data symbol and ending with a first available data symbol.

Techniques for supporting relay communication with subframe staggering are described. For subframe staggering, subframes of different relays are staggered from one another, which can increase the number of potential backhaul subframes. In one design, a first relay determines its access subframes and backhaul subframes, which correspond to different non-overlapping subsets of the subframes of the first relay. The first relay communicates with at least one UE during the access subframes and communicates with a base station during the backhaul subframes. The subframes of the first relay are offset from the subframes of a second relay communicating with the base station. In one design, the access subframes of the first relay includes all subframes with either even or odd indices, which can support data transmission with HARQ. In one design, at least one access subframe corresponds to at least one reserved subframe having reduced transmit power from the base station.

A system and method of managing adjustment of synchronization timing for handover of a mobile relay is disclosed. The method includes repositioning coverage of the mobile relay from a first network access point to a second network access point and adjusting a synchronization timing of the mobile relay in an asynchronous network of the wireless communication system.

摘要:
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.
