摘要:
Certain aspects of the present disclosure provide a method for wireless communications. The method generally includes allocating resources of a backhaul link between a donor base station and a relay base station to the relay station for communicating with the donor base station and transmitting a control channel indicating the allocated resources to the relay base station, wherein the control channel is transmitted on a subset of physical resource blocks (PRBs) of subframes assigned for downlink communications on the backhaul link.
摘要:
Pseudo-random sequences of a plurality of user equipment specific reference signals (UE-RSs) for use by a plurality of user equipments (UEs) are initialized, the initialization of each pseudo-random sequence associated with each UE-RS being independent of a specific UE identifier and independent of a resource bandwidth assigned to a specific UE. Pseudo-random sequences of the UE-RSs are generated. At least one of the pseudo-random sequences is mapped to a portion of common resources for at least one UE among the plurality of UEs.

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.

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.

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.
