  • Publication number: 20140126524
    Abstract: In a wireless network, simultaneous support of distributed and contiguous sub-carrier allocation may be accomplished in the same sub-frame or time zone. Techniques are described herein that can be used to allocate distributed and/or contiguous basic (physical) resource blocks to users by specifying a codebook index and parent node. Techniques are described herein that can be used to flexibly set a number of sub-channels over which a subscriber station indicates a channel quality indicator to a base station. Sub-channels may be represented as nodes and may be grouped to include a parent node and child nodes. By specifying a code book to use and a parent node, the channel quality indicator of the parent and children nodes can be indicated.

  • Patent number: 8677223
    Abstract: An apparatus and method for processing fast feedback payload data to generate symbols for transmission through a fast feedback channel in a wireless network are presented. The technique first encodes payload data using a tail biting convolutional code. The encoded bits are then de-multiplexed to five different data subblocks in a sequential fashion. Subblock interleaving is then used to interleave the data of the subblocks according to a predetermine scheme. A bit selector then selects interleaved subblock bit for output. The selected bits may then be modulated by a modulator using quadrature phase shift keying (QPSK). The resulting symbols may then be mapped to a predetermined fast feedback subcarriers within a feedback channel.

  • Patent number: 8660069
    Abstract: Disclosed is a method for reducing number of bits in a Media Access Protocol (MAP) message. The MAP message comprises a plurality of information elements grouped into one of a first set of information elements and a second set of information elements. The first set of information elements are arranged in a pre-defined order and each of the second set of information elements is inserted into one of a prefix position to the pre-defined order, a suffix position to the pre-defined order and an intermediate position in-between two information elements in the pre-defined order. Each information element of the second set of information elements is then coded based on position of the information element relative to the position of the first set of information elements in the pre-defined order, thereby reducing the number of bits in the MAP message.

  • Patent number: 8599768
    Abstract: Group size indications may be distributed from a base station to a mobile station in the form of assignment-advanced-MAP transmit control signaling. The signaling control information may be sent to a station, such as a mobile station, using a table that indicates the size of a group based on coding rates, such as one-half and one-quarter coding rates. Waste may be controlled by determining a size based on using an unoccupied resource in a group that is adjacent to data resource for data transmission by the station. However, an unoccupied resource in a group that is not adjacent to a data resource is not used for data transmission and is, therefore, wasted.

  • Patent number: 8588121
    Abstract: Disclosed is a method for improving power efficiency of subscriber stations in a communication network. A subscriber station is uniquely identified by a base station using a connection Identifier (CID). The method includes splitting CIDs of subscriber stations to form a plurality of first parts and a plurality of second parts. The method includes generating an index including a plurality of entries and transmitting the index to a plurality of subscriber stations by the base station. One or more subscriber stations switch to a power-saving mode on absence of a match between each entry of the plurality of entries with an equivalent part of CIDs associated with the one or more subscriber stations, thereby conserving power and improving power efficiency of the subscriber station. Further, at least one information element in a sub-MAP message may be compressed to reduce overhead.

  • Publication number: 20130301438
    Abstract: An apparatus and method that allow user equipment (UE) to transmit information directly with other user equipment, using a device-to-device (D2D) mode is disclosed herein. A first D2D UE (dUE1) that wishes so communicate to a second D2D UE (dUE2) in D2D mode makes various communications requests to an Evolved Node B (eNB), which can facilitate the connection between the dUE1 and the dUE2. Among these requests are to make the D2D connection via WiFi instead of via Long Term Evolution (LTE). The eNB determines the WiFi capabilities of dUE1 and dUE2, then assigns a subset of available channels to be scanned by dUE1 and a separate subset of available channels to be scanned by dUE2. Thereafter, the eNB can assign a WiFi channel based on the scans performed by dUE1 and dUE2.
