摘要： Methods, systems, and devices for wireless communications are described. A transmitted may use a closed loop precoder for line-of-sight (LOS) multiple-input multiple-output (MIMO) communications that uses information such as distance feedback or LOS MIMO channel state feedback. A closed loop precoder may be associated with less overhead than a precoder based on full channel knowledge, such as an SVD precoder. A receiver may estimate a channel based on channel state information reference signals transmitted by the transmitter and calculate a spectral efficiency for one or more precoders of a set of precoders associated with the channel for a LOS MIMO mode. The receiver may send feedback to the transmitter that indicates a selected precoder of the set of LOS MIMO precoders based on the calculated spectral efficiencies. The transmitter may precode messages using the reported closed loop precoder.

摘要： Systems, apparatuses, and methods are disclosed for a relay station for use in a communication system with a base station and user equipment (UE). The relay station may decode and forward a data packet between the base station and the UE that the relay station services in which the relay station does not establish a direct link with the UE. Further, the relay station indicates successful decoding of the data packet to the base station such that if the base station receives information indicating successful decoding of the data packet from the relay station, the base station terminates a HARQ transmission on a direct link between the base station and the UE such that HARQ retransmission time is extended compared to direct communications between the base station and the UE.

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.

摘要： Systems and methodologies are described that facilitate secure interference management in a wireless communication system. Techniques are described herein to enable a terminal jammed by a nearby base station to submit a request to the nearby base station to set aside interlaces and/or other communication resources while preventing attacks wherein such requests are submitted arbitrarily. As described herein, a base station receiving a request for reservation of resources can require proof that an entity requesting the reservation is actually jammed by the base station by constructing and transmitting a signal using random number and/or other information such that the information can be correctly decoded only at or above a minimum signal quality. A tiered technique is additionally described herein, wherein multiple signals are constructed and transmitted such that the respective signals are correctly decodable at varying signal quality thresholds.

摘要： Systems and methodologies are described that facilitate assigning carriers to access points based on power class. Devices can accordingly evaluate cells provided by the access points to select a cell with an optimal SNR or path loss for communication regardless of power class, since lower powered cells will not be interfered by higher powered cells communicating over different carriers. Cross-carrier operation is also provided where access points can transmit downlink signals according to carrier assignment information while receiving uplink signals over other carriers. Thus, once an optimal cell is determined, downlink control data can be received over the assigned carrier to ensure receipt without interference, but uplink transmissions can occur over multiple carriers to facilitate increased throughput using one or more reuse schemes.

摘要： Method and apparatus that provide for broadcast multicast services in an ultra mobile broadband network are disclosed. A broadcast transmission structure provides for efficient indexing of subbands reserved for BCMCS. Transmissions on the logical channels are segmented into error control blocks beginning with zero or one MAC packet received by a MAC layer. A transmitting entity appends parameters relating to content change within a next ultraframe at end of every broadcast packet that is not a stuffing packet. A mapping message of multiple Physical Layer groups addresses a single logical channel when SFN (Single Frequency Network) coverage of an associated subband group is different from SFN coverage of the logical channel.

摘要： Providing for interference reduction and/or avoidance utilizing backhaul signaling between wireless access points (APs) of a wireless access network (AN) is described herein. By way of example, an interference avoidance request (IAR) can be issued by an AP to reduce signal interference on forward link (FL) and/or downlink (DL) transmissions by neighboring APs. The IAR can be routed via a backhaul network and/or over-the-air via access terminals (ATs) coupled with the AP or one or more interfering APs. Upon receiving the IAR, an interfering AP can determine reduced transmit power levels for FL and/or RL transmissions and respond to the IAR. The response can include reduced power levels and can be sent via the backhaul network or OTA. By employing the backhaul network in full or in part, interference avoidance can be conducted even for semi-planned or unplanned heterogeneous networks coupled by the backhaul.
摘要翻译：本文描述了在无线接入网络（AN）的无线接入点（AP）之间利用回程信令来提供减少干扰和/或避免的干扰。作为示例，AP可以发出干扰避免请求（IAR），以减少相邻AP在前向链路（FL）和/或下行链路（DL）传输上的信号干扰。 IAR可以经由回程网络和/或通过与AP或一个或多个干扰AP耦合的接入终端（AT）进行路由。在接收到IAR时，干扰AP可以确定用于FL和/或RL传输的降低的发射功率电平并响应于IAR。响应可以包括降低的功率级别，并且可以通过回程网络或OTA发送。通过全面或部分采用回程网络，即使对于通过回程耦合的半计划或计划外异构网络，也可以进行干扰回避。

摘要： Techniques for selecting a serving base station for a terminal in a wireless communication network are described. In one design, multiple candidate base stations for the terminal may be identified, with each candidate base station being a candidate for selection as the serving base station for the terminal. The multiple candidate base stations may include base stations with different transmit power levels and/or may support interference mitigation. One of the multiple candidate base stations may be selected as the serving base station. In one design, the serving base station may be selected based on at least one metric for each candidate base station. The at least one metrics may be for pathloss, effective transmit power, effective geometry, projected data rate, control channel reliability, network utility, etc. The selected candidate base station may have a lower SINR than a highest SINR among the multiple candidate base stations.
