摘要： Certain aspects of the present disclosure relate to a method for sending control information to multiple user terminals that share the same resources in a Spatial Division Multiple Access (SDMA) wireless system. The control information can be transmitted from an access point over a physical downlink control channel (PDCCH) that is common for a plurality of user terminals. The overall PDCCH overhead can thus be reduced due to a smaller number of required PDCCH in the SDMA wireless system.
摘要翻译：本公开的某些方面涉及用于向在空分多址（SDMA）无线系统中共享相同资源的多个用户终端发送控制信息的方法。控制信息可以通过对于多个用户终端公用的物理下行链路控制信道（PDCCH）从接入点发送。由于SDMA无线系统中所需的PDCCH数量较少，因此可以减少总体PDCCH开销。

摘要： Systems and methodologies are described that facilitate allocating uplink resources to mobile devices to employ to signal acknowledgment indicators. Persistently scheduled mobile devices can be explicitly assigned uplink resources. Dynamically scheduled mobile device can utilize a one-to-one mapping to identify uplink resources based upon a downlink control channel index. The one-to-one mapping can be revised to remove associations between downlink control channel indices and resources allocated to persistently scheduled users and/or reserved for other control signaling in a mixed resource block. In addition, downlink control channel indices can be selected to avoid collisions between dynamic and persistent users.

摘要： Aspects of the present disclosure relate to techniques that may help enable the determination of uplink resource allocation in systems that support dynamic uplink-downlink subframe configurations. An example method generally includes receiving signaling indicating a dynamic uplink-downlink (UL-DL) subframe configuration, determining hybrid automatic repeat request (HARQ) acknowledgment/negative acknowledgment (ACK/NACK) timing based on a reference UL-DL subframe configuration, and determining HARQ resource allocation based on the dynamic UL-DL subframe configuration.

摘要： User equipment (UE) associated with synchronous networks operate in a synchronous mode while UEs associated with asynchronous networks operate in an asynchronous mode. When operating in a synchronous mode, a UE can significantly improve performance of synchronization signal detection, data decoding, and tracking loop management by using the interference cancellation (IC) techniques that are not available in an asynchronous mode of operation. Obtaining synchronization indicators and determining the synchronization status of the current network by UE is disclosed. The determination may be based on the synchronization indicator, whether detected through signal detection, signal measurements, signal analysis, or the like.

摘要： Techniques for performing interference and power control in a wireless communication system are described. An asymmetric power control scheme adjusts the transmit power of a user equipment (UE) in an asymmetric manner, e.g., with different up and down step sizes. In one design, a parameter value may be determined based on received SINR of at least one Node B. Up and down steps may be determined based on the parameter value and may have different sizes. At least one overloading indicator from at least one neighbor Node B may be obtained. The transmit power of the UE may be adjusted based on the up and down steps and the at least one overloading indicator. For example, the transmit power may be increased by the up step if an overloading indicator from the strongest neighbor Node B is not received and may be decreased by the down step otherwise.

摘要： A system and method for facilitating resource management in OFDM systems is provided. The system permits different and flexible resource cell metric operations levels (e.g. uplink load management, admission control, congestion control, signal handoff control) for different sub-bands. For the uplink load management, there are multiple distinct load operation points (e.g. IoT, RoT) per sub-band group instead of the same operation level across the entire available band. The sub-band groups encompass the entire band. The facilitation system also comprises a variety of transmitting protocols, command increment variable stepsize methods and robust command response methods. The system thus provides more flexible reverse link resource management and more efficient utilization of the bandwidth.

摘要： System(s) and method(s) are provided for inter-cell power control in the presence of fractional frequency reuse in a wireless communication system. Transmission power control of a terminal (210); and ensuing inter-cell interference mitigation, is accomplished by receiving load indicators (23Oi) from non-serving sectors (246i), decoding those load indicators corresponding to the non-serving sectors that operate in the same frequency bands as the terminal, and adjusting the transmission power according to the states of the decoded load indicators in conjunction with the associated non-serving sector forward link signal-to-interference and-noise ratio at the terminal. The states of the load indicators reflect magnitudes of interference metrics with respect to threshold values. Load indicators can also be conveyed by the non-serving sector to a base station (260) serving the terminal through a backhaul (250) communication, and said base station can schedule an adjusted transmission power for the terminal.
