摘要： Systems and methodologies are described that facilitate indicating channel resource usage information for receiving additional channel resources in a wireless network. An access point can initially receive a set of channel resources from a network controller for providing wireless network access to one or more devices. The access point can grant and/or deny requests for one or more of the channel resources from a plurality of devices and can feedback information to the network controller regarding the granting/denying. The network controller can determine a load on the access point based at least in part on the feedback information and adjust channel resource allocation based on the load. Thus, where an access point has granted close to capacity of allocated resources to one or more devices, the network controller can provide additional resources to the access point based on received feedback information related to the granted resources.
摘要翻译：描述了便于指示用于在无线网络中接收附加信道资源的信道资源使用信息的系统和方法。接入点可以最初从网络控制器接收一组信道资源，以提供对一个或多个设备的无线网络接入。接入点可以授权和/或拒绝来自多个设备的一个或多个信道资源的请求，并且可以向网络控制器反馈关于授权/拒绝的信息。网络控制器可以至少部分地基于反馈信息来确定接入点上的负载，并且基于负载调整信道资源分配。因此，在接入点已经向一个或多个设备授予接近分配的资源的容量的地方，网络控制器可以基于接收到的与授权资源相关的反馈信息向接入点提供附加资源。

摘要： Techniques for supporting operation with enhanced uplink are described. A user equipment (UE) may select a signature from a set of signatures available for random access for enhanced uplink, generate an access preamble based on the selected signature, and send the access preamble for random access while operating in an inactive state. The UE may receive allocated resources (e.g., for an E-DCH) for the UE from a shared control channel (e.g., an HS-SCCH). In one design, the UE may determine a pre-assigned UE identity (ID) associated with the selected signature, de-mask received symbols for the shared control channel based on the pre-assigned UE ID, decode the demasked symbols to obtain a codeword, and determine the allocated resources based on the codeword. The UE may send data to a Node B using the allocated resources while remaining in the inactive state.
摘要翻译：描述了用于支持具有增强上行链路的操作的技术。用户设备（UE）可以从可用于增强上行链路的随机接入的签名组中选择签名，基于所选择的签名生成接入前导码，并在无效状态下操作时发送用于随机接入的接入前导码。 UE可以从共享控制信道（例如，HS-SCCH）接收针对UE的分配的资源（例如，用于E-DCH）。在一种设计中，UE可以确定与所选择的签名相关联的预先分配的UE标识（ID），基于预先分配的UE ID对共享控制信道的接收符号进行解密，对被解除的符号进行解码以获得码字，并且基于码字来确定所分配的资源。 UE可以在保持处于非活动状态的同时使用所分配的资源向节点B发送数据。

摘要： A base station receiver, a computer program product operable at a base station, and a method operable at a base station receiver, for receiving uplink transmit diversity transmissions utilizing a master/slave scheme at the receiver. One or more tracking loops, such as a searcher task, a time tracking loop, or a frequency tracking loop may be implemented at the base station receiver to determine compensation values, such as finger timings for a rake receiver or frequency compensation values, in accordance with characteristics of a first received pilot channel transmitted utilizing a first precoding weight vector. Here, corresponding compensation values may be derived for the reception of a secondary pilot channel transmitted utilizing an precoding weight vector orthogonal to the first precoding weight vector, simply based on those determined for the first pilot channel.

摘要： Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In some particular aspects, scheduling of the uplink MIMO transmissions may make a determination between single stream, rank=1 transmissions and dual stream, rank=2 transmissions based on various factors. Further, when switching between single and dual stream transmissions in the presence of HARQ retransmissions of failed packets, the scheduling function may determine to transmit the HARQ retransmissions on a single stream transmission or to transmit the HARQ retransmissions on one stream while transmitting new packets on the other stream.

摘要： Wireless user equipment (UE) operating in a wireless communication system may operate in a state, for example, the CELL_FACH state in UMTS, that does not allow for soft handoff from one cell to another. This inability to engage in soft handover may lead to intercell interference at a non-serving cell when the UE transmits on its uplink in close proximity to the non-serving cell. Therefore, provided in the present disclosure is method of wireless communication, which includes receiving a neighbor cell identification set indicating one or more neighbor cells, receiving a relative grant channel resource index corresponding to a relative grant channel shared by at least one of the one or more neighbor cells, detecting intercell interference associated with a user equipment (UE) in the one or more neighbor cells, and transmitting a non-serving relative grant message to the UE on the relative grant channel.

摘要： A base station can employ a shared resource, such as a control channel, for communication with a mobile device. The mobile device can be granted the exclusive access to the shared resource for a limited time. The exclusive access can be such that there is not a limit in message size that can be transferred across the shared resource. To improve operation, the exclusive grant can be applied until it is determined that appropriate packets are transferred.

摘要： Systems and methodologies are described that facilitate efficient power control command management in a wireless communication environment. As described herein, techniques can be utilized by a Node B and/or other network access point to compensate for differences between uplink slot boundaries and a power control command combining period associated with the uplink slot. For example, the timing of Transmitter Power Control (TPC) bit transmission can be altered as described herein such that, if a given cell or cell sector is associated with a radio link set of size 2 or greater and a TPC timing offset of size 2 or less, TPC command information can be buffered and/or otherwise delayed to a slot following the slot in which corresponding channel measurements are obtained in order to prevent efficiency loss associated with combining TPC bits of inverse polarity corresponding to multiple disparate slots.
