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： The present disclosure provides methods and apparatuses for improved Iub link congestion management based on a dynamic scaling of flow control request message transmission in multiflow wireless environments. For example, in an aspect, methods and apparatuses are provided for receiving, at a NodeB, a data request from one or more user equipment (UE), wherein each data request corresponds to a flow and the one or more UE is served by a plurality of NodeBs, generating a flow control request corresponding to each flow in response to each data request, and sending each flow control request to a radio network controller (RNC). Thereafter, a Node B may receive data in response to each flow control request, determine a congestion state based on a downlink delay from the RNC detected in the received data, and scale a subsequent one or more flow control requests based on the determined congestion state.

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.
摘要翻译：在无线通信系统中操作的无线用户设备（UE）可以在例如UMTS中的CELL_FACH状态的状态下工作，不允许从一个小区到另一个小区的软切换。当UE在与非服务小区非常接近的上行链路上发送时，这种无法进行软切换可能导致非服务小区的小区间干扰。因此，在本公开中提供的是无线通信方法，其包括：接收指示一个或多个相邻小区的相邻小区标识集，接收与由所述相邻小区中的至少一个共享的相对授权信道相对应的相对授权信道资源索引，更多的相邻小区，检测与所述一个或多个相邻小区中的用户设备（UE）相关联的小区间干扰，以及在所述相对授权信道上向所述UE发送非服务相对授权消息。

摘要： A method and apparatus for wireless communication may provide a multi-link RLC sublayer in an RNC capable of allocating RLC PDUs among a plurality of MAC entities for use in a Multi-Point HSDPA network. Some aspects of the disclosure address issues relating to out-of-order delivery of the RLC PDUs to a UE, such as unnecessary retransmissions. That is, the disclosed multi-link RLC may be capable of distinguishing between sequence number gaps that are caused by physical layer transmission failures and those caused merely by skew.

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： Techniques for scheduling users for transmission on the uplink in a wireless communication system are described. A cell may perform interference cancellation for uplink transmissions and may observe lower effective noise and interference due to interference cancellation. The lower effective noise and interference may allow the cell to operate with a higher effective target load, which may support a higher overall throughput for the cell. In one design, an effective target load for a cell using interference cancellation may be determined, e.g., based on a target rise-over-thermal (RoT) for the cell and an interference cancellation efficiency factor. An available load for the cell may be determined based on the effective target load, which may be higher than a target load for the cell without interference cancellation. Users in the cell may then be scheduled for transmission on the uplink based on the available load.
