摘要： A method an apparatus is described for providing feedback for closed-loop transmitting with multiple transmit and receive antennas. The method includes a first step (900) of providing a codebook containing sets of weightings for each data stream of the multiple transmit antennas with each set identified by an index known to a transmitter and a receiver. The same codebook is utilized for any number of data streams up to the number of transmit antennas. A next step (902) includes measuring a composite channel between the transmitter and receiver. A next step (904) includes determining at least one performance metric for each set of weightings in the codebook. A next step (906) includes selecting preferred weightings for each data stream in response to the performance metrics. A next step (908) includes feeding back an index of the preferred weightings to the transmitter for use in subsequent transmissions.

摘要： A communication system (100) provides, via a serving Node B (123), scheduling information required by a user equipment (UE) (102) to determine a start time for each Node B of multiple Node Bs (120, 123, 126) with respect to a multicast, by each Node B of the multiple Node Bs, of soft combinable MBMS data. The UE may then use the scheduling information to synchronize a soft combining of the MBMS data received by the UE via each of the multiple Node Bs, even when the multicasts via the multiple Node Bs are not synchronized. However, while the multicasts of frames of data associated with an MBMS service by different Node Bs need not be synchronized, synchronized multicasts are preferable for soft combining. Therefore, the communication system further provides for a synchronization by a network controller (130) of the multicasts of the MBMS data by the multiple Node Bs.
摘要翻译：通信系统（100）经由服务节点B（123）提供用户设备（UE）（102）所需的调度信息以确定多个节点B（120,123,126）中的每个节点B的开始时间，关于由多个节点B中的每个节点B进行的多播软组合MBMS数据。即使当经由多个节点B的多播不同步时，UE也可以使用调度信息来同步UE经由多个节点B中的每一个接收的MBMS数据的软组合。然而，尽管不同节点B与MBMS服务相关联的数据帧的多播不需要同步，但同步多播对于软组合而言是优选的。因此，通信系统还通过网络控制器（130）提供多个节点B对MBMS数据的多播的同步。

摘要： A method and apparatus for providing adaptive bearer configuration for MBMS delivery is disclosed. A first aspect of the present disclosure is a method of operating a wireless infrastructure entity (103) wherein a plurality of common radio resources (303) are allocated for receiving combined responses from a plurality of mobile stations (109). A request message, similar to a request for counting, is broadcast to all mobile stations (109) within a coverage area (105) and may indicate a range, for example a signal-to-noise-and-interference ratio range. Mobile stations (109) responding to the request, use specific resources (303) corresponding to respective range values. The infrastructure (103) may use the received information to determine a modulation and coding scheme for PTM broadcast. The total number of responses to the request message may be limited by providing a probability factor within the request message.

摘要： In a telecommunication system (10) for providing multimedia broadcast services to many user equipments (40-45), a physical random access channel (39) is provided for uplink transmission of power control information from the user equipments to a radio site (30, 35). Based upon a comparison of signal-to-noise ratios (53) each particular user equipment sends (55) or inhibits from sending a power control signal to the radio site to which it is coupled. When the radio site of the telecommunication system detects a power control signal (73), the radio site adjusts the transmission power of a broadcast channel intended for reception by multiple user equipments (75) to be incrementally greater than the previous power (81). For lack of detection of a power control signal, adjusts the transmission power of a broadcast channel to be incrementally lower than the previous power.
