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： 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 (dominant interfer) er and a second class of base stations (victim cells). 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 (power resricted). The second signal may be transmitted within the region of the Physical Downlink Shared Channel (PDSCH).

摘要： Systems and methodologies are described that facilitate transmitting positioning reference signals (PRS) differently for passive distributed elements. PRSs for passive distributed elements can be transmitted over disparate resources than those utilized for PRSs at a related access point, using different symbol sequences, and/or the like. In this regard, wireless devices can differentiate between PRSs from access points and those from passive distributed elements, which can mitigate confusion for processes involving such RSs, such as position determining. Alternatively, passive distributed elements can refrain from transmitting PRSs, and a corresponding access point can indicate to wireless devices to only determine positioning based on PRSs. Thus, the wireless devices can utilize the PRSs transmitted from the access point (and not other reference signals transmitted from the passive distributed element) to determine a position.
摘要翻译：描述了有助于以无源分布式元件不同地传送定位参考信号（PRS）的系统和方法。用于被动分布式元件的PRS可以在不同资源上传输，而不是使用不同的符号序列等在相关接入点用于PRS的资源。在这方面，无线设备可以区分来自接入点的PRS和来自被动分布元件的PRS，其可以减轻涉及这种RS的过程的混淆，诸如位置确定。或者，被动分布式元件可以避免传输PRS，相应的接入点可以向无线设备指示仅基于PRS确定定位。因此，无线设备可以利用从接入点发送的PRS（而不是从被动分布式元件发送的其他参考信号）来确定位置。

摘要： Providing for wireless communication involving supplemental wireless nodes is described herein. By way of example, prior signaling is employed between a macro base station and a set of associated supplemental nodes to support pending wireless communication with a user terminal. In some aspects, the prior signaling can include control or data traffic transmitted to or received from the user terminal. In addition, the supplemental nodes can synchronize transmission or reception of the control or data traffic transmissions with similar transmission or reception of the macro base station. In some aspects, the supplemental nodes can also replicate pilot signal transmissions on OFDM symbols employed by the macro base station for pilot signals, to give consistent downlink channel for both traffic and pilot signals. Accordingly, the user terminal observes consistent pilot transmissions over various time slots, as well as concurrent traffic transmissions that can generally be decoded with a common reference signal.

摘要： Techniques for transmitting and detecting for overhead channels and signals in a wireless network are described. In an aspect, a base station may blank (i.e., not transmit) at least one overhead transmission on certain resources in order to detect for the at least one overhead transmission of another base station. In one design, the base station may (i) send the overhead transmission(s) on a first subset of designated resources and (ii) blank the overhead transmission(s) on a second subset of the designated resources. The designated resources may be resources on which the overhead transmission(s) are sent by macro base stations. The base station may detect for the overhead transmission(s) from at least one other base station on the second subset of the designated resources. In another aspect, the base station may transmit the overhead transmission(s) on additional resources different from the designated resources.

摘要： Providing for improved implementation of supplemental wireless nodes in a wireless base station deployment is described herein. By way of example, a donor base station is configured to send a schedule of data transmission to and from a set of UEs served by the base station, and further can provide the schedule and identifiers for the set of UEs to one or more wireless nodes serving the base station. Respective access channel measurements between respective UEs and respective wireless nodes can be forwarded to the base station, which in turn can identify optimal access channels for the set of UEs. Additionally, the donor base station can schedule multiple data transmissions on these access channels in a common transmission time slot, to achieve cell-splitting gains for the data transmissions. Range boosting, differential coding, and supplemental channel quality mechanisms are also provided for various wireless communication arrangements described herein.
