摘要： Methods are disclosed for improving communications on feedback transmission channels, in which there is a possibility of bit errors. The basic solutions to counter those errors are: proper design of the CSI vector quantizer indexing (i.e., the bit representation of centroid indices) in order to minimize impact of index errors, use of error detection techniques to expurgate the erroneous indices and use of other methods to recover correct indices.

摘要： Methods and devices for operating a wireless communication device that can communicate with at least two different co-located APs are described. The device may receive, from a first AP, information corresponding to a second AP of the co-located APs. The information corresponding to the second AP may include state information of the second AP. The device may establish a first wireless link with the first AP using a first frequency of the first AP and establish a second wireless link with the second AP using a second frequency which is different than the first frequency. The device may simultaneously receive first data from the first AP and second data from the second AP.

摘要： Methods and apparatus are described for mitigating intercell interference in wireless communication systems utilizing substantially the same operating frequency band across multiple neighboring coverage areas. The operating frequency band may be shared across multiple neighboring or otherwise adjacent cells, such as in a frequency reuse one configuration. The wireless communication system can synchronize one or more resource allocation regions or zones across the multiple base stations, and can coordinate a permutation type within each resource allocation zone. The base stations can coordinate a pilot configuration in each of a plurality of coordinated resource allocation regions. Subscriber stations can be assigned resources in a coordinated resource allocation region based on interference levels. A subscriber station can determine a channel estimate for each of multiple base stations in the coordinated resource allocation region to mitigate interference.

摘要： 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.

摘要： 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.

摘要： A method of encapsulating data and a single frequency network configured to perform the method are disclosed. A content stream of data packets is received, and the data packets in the content stream are formatted in accordance with a first protocol. Information identifying a container size established for the content stream is received. The data packets formatted in accordance with the first protocol are fragmented and packed to form data units formatted in accordance with a second protocol, and the data units are sized based on the container size. The data units formatted in accordance with the second protocol are encapsulated to form second protocol data packets. The second protocol data packets are provided to a transmitter that is synchronized to one or more transmitters in a single frequency network so that each transmitter in the single frequency network broadcasts a same signal that includes the second protocol data packets.

摘要： Methods and devices for operating a wireless communication device that can communicate with at least two different wireless networks using a single radio frequency modem are described. The communication device attaches to a first wireless network through the radio frequency (RF) modem, and then detaches from the first wireless network at a predetermined time before a start time of a selected event on a second wireless network. The device attaches to the second wireless network using the same RF modem before the start time of the selected event and collects at least a portion of event data associated with the selected event. After collecting at least a portion of event data, the device detaches from the second wireless network and re-attaches to the first wireless network.
