    Abstract: An advanced technology frame structure is described herein. The advanced technology frame structure can enhance a first technology frame structure in dimensions of time, frequency, or a combination of time and frequency. A second technology frame structure time division multiplexes second technology subframes with the first technology downlink and uplink subframes. The first technology downlink subframe can be divided into a first technology downlink subframe and one or more second technology downlink subframes. Similarly, the first technology uplink subframe can be divided into a first uplink subframe and one or more second technology uplink subframes. These principles can be expanded upon and can be applied in many communication systems.

    Abstract: Methods and apparatus for communicating and utilizing persistent allocation of resources are described herein. A base station may allocate persistent resources to a client station, and may associate the client station or persistent resource allocation with a particular shared NACK channel. The base station may monitor the NACK channel for a NACK indicating a map error. The base station may monitor the resource allocation to implicitly determine a map error. The base station may resend one or more persistent resource allocation information elements in response to the NACK or implicit error determination. A client station having a persistent resource allocation may monitor persistent resource allocation information elements in map messages and/or may indicate failure to receive a persistent resource allocation information element in a NACK message on a shared NACK channel.

    Abstract translation: 本文描述了用于传送和利用资源的持续分配的方法和装置。 基站可以向客户站分配持久资源,并且可以将客户端站或持久资源分配与特定的共享NACK信道相关联。 基站可以监视NACK信道用于指示地图误差的NACK。 基站可以监视资源分配以隐含地确定地图误差。 基站可以响应于NACK或隐含错误确定重新发送一个或多个持久资源分配信息元素。 具有持续资源分配的客户站可以监视地图消息中的持久资源分配信息元素和/或可以指示在共享NACK信道上的NACK消息中接收持续资源分配信息元素的失败。

    Abstract: A method of transmission over multiple wireless channels in a multiple antenna system includes storing channel modulation matrices at a transmitter; receiving quantized channel state information at the transmitter from plural receivers; selecting a transmission modulation matrix using the quantized channel state information from the stored channel modulation matrices; and transmitting over the multiple channels to the plural receivers using the selected transmission modulation matrix. In another embodiment, the method includes storing, at one or more receivers, indexes of modulation matrices generated by a capacity enhancing algorithm; upon a selected one of the one or more receivers receiving a transmission from the transmitter, the selected receiver selecting a modulation matrix from the stored modulation matrices that optimizes transmission between the transmitter and the selected receiver; the selected receiver sending an index representing the selected modulation matrix; and receiving the index at the transmitter from the selected receiver.

    Abstract: A multicast broadcast service controller is disclosed. The MBSC processes multicast broadcast data streams for transmission to access service network gateways or base stations. The MBSC includes a MBSC core processor for establishing time synchronization information used by the access service network gateways or base stations to synchronously transmit data streams. The MBSC core processor selects streams for transmission in a time diversity interval (TDI) and builds multicast broadcast (MBS) region content based on the selected streams and configuration information. The MBS region content includes timing synchronization information, resource information and MBS region content location information. A MBS region distribution module (MRD) transmits the MBS region content to the access service network gateways or base stations.
