    摘要： For range expansion, a determination to enter range expansion may be made based on a signal strength differential for user equipment (UE) communications between a first class of base stations and a second class of base stations. If the signal strength differential is beyond a certain threshold, range expansion may be implemented. In range expansion, a signal is transmitted, on a resource coordinated with at least one of the first class of base stations, from one of the second class of base stations to the UE which could experience dominant interference from one of the first class of base stations if coordination were not performed. Transmission power may be reduced from one of the first class of base stations on that resource. The second signal may be transmitted within the region of the Physical Downlink Shared Channel.

    摘要： 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.

    摘要： Methods and apparatuses are provided that facilitate associating with relays in a wireless network. A device can select whether to utilize relay assistance where present based at least in part on measuring one or more determined or projected parameters related to the relay. Where utilizing a relay results in user-plane data channel conditions above a threshold level and control channel conditions below a threshold level, a serving base station can determine whether to employ another base station to serve the device, jointly serve a relay with an additional base station, and/or the like.

    摘要： Aspects are disclosed for operating a relay via an MBSFN-based backhaul link. Control resources are allocated, which include a first set of control resources and a second set of control resources. For some embodiments, a portion of the first set of control resources is concatenated with a portion of the second set of control resources to form a concatenation of resources whereas, in other embodiments, an indication scheme is implemented to provide an indication of a first or second allocation size respectively associated with the first and second set of control resources. At least one control signal is then transmitted which includes at least one of the concatenation or the indication. Other disclosed embodiments are directed towards configuring a user equipment to decode a control signal generated according to the aspects disclosed herein.
