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.

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.

摘要： Techniques for supporting communication in dominant interference scenarios are described. In an aspect, communication in a dominant interference scenario may be supported with time division multiplex (TDM) partitioning of downlink control resources. For TDM partitioning, different base stations may be allocated different time resources. Each base station may send its control information in its allocated time resources and may avoid sending control information (or may send control information at a lower transmit power level) in time resources allocated to other base stations. In another aspect, communication in a dominant interference scenario may be supported with frequency division multiplex (FDM) partitioning of uplink control resources. For FDM partitioning, different base stations may be allocated different frequency resources. In one design, TDM partitioning may be used for downlink control resources, and FDM partitioning may be used for uplink control resources.

摘要： Techniques for supporting communication in dominant interference scenarios are described. In an aspect, communication in a dominant interference scenario may be supported with cross-subframe control. Different base stations may be allocated different subframes for sending control information. Each base station may send control messages in the subframes allocated to that base station. Different base stations may have different timelines for sending control messages due to their different allocated subframes. With cross-subframe control, control information (e.g., grants, acknowledgement, etc.) may be sent in a first subframe and may be applicable for data transmission in a second subframe, which may be a variable number of subframes from the first subframe. In another aspect, messages to mitigate interference may be sent on a physical downlink control channel (PDCCH).
摘要翻译：描述了在主要干扰场景中支持通信的技术。在一方面，可以通过跨子帧控制来支持主要干扰场景中的通信。可以为不同的基站分配不同的子帧以发送控制信息。每个基站可以在分配给该基站的子帧中发送控制消息。不同的基站可能具有不同的时间线，用于由于其不同的分配子帧而发送控制消息。利用跨子帧控制，可以在第一子帧中发送控制信息（例如，授权，确认等），并且可以适用于第二子帧中的数据传输，其可以是来自第一子帧的可变数量的子帧。在另一方面，可以在物理下行链路控制信道（PDCCH）上发送用于减轻干扰的消息。

摘要： Techniques for dynamically selecting subframe formats in a wireless network are described. In an aspect, a base station may dynamically switch between different subframe formats to support communication for different types of user equipments (UEs). In one design, the base station may declare a set of subframes as multicast/ broadcast single frequency network (MBSFN) subframes for first/legacy UEs. The base station may send signaling conveying the set of subframes as MBSFN subframes to the legacy UEs. The base station may dynamically select the formats of the set of subframes for second/new UEs, e.g., on a per subframe basis. The format of each subframe may be selected from a plurality of formats, which may include at least one regular subframe format, at least one MBSFN subframe format, and/or at least one blank subframe format. The base station may send transmissions in the set of subframes based on the selected formats.
