  • Publication number: 20130188734
    Abstract: An electronic device configured for high throughput binarization mode is described. The electronic device includes a processor and instructions stored in memory that is in electronic communication with the processor. The electronic device obtains a block of transformed and quantized coefficients (TCQs). The electronic device determines whether a high throughput binarization mode condition is met. If the condition is met, the electronic device uses the high throughput binarization mode to process the block. If the condition is not met, the electronic device does not use the high throughput binarization mode to process the block. The electronic device transmits the generated first or second bitstream to a decoder.

  • Patent number: 8472416
    Abstract: A system and method are provided for maintaining a hybrid coordinator (HC) in a wireless communications local area network (LAN). The method comprises: a station (STA) seeking a guaranteed quality of service (QoS); establishing a basic service set (BSS) through association with an access point (AP); the AP selecting a HC from STAs in the BSS; the AP broadcasting the HC information to STAs in the BSS; and, the STA initiating a transmission specification (TSPEC) with the HC. In one aspect, selecting an HC from STAs in the first BSS includes integrating the HC function into the AP. Then, a STA seeking a guaranteed quality of service (QoS): receives a broadcast message including a list of potential APs; and, communicates with an AP from the broadcast list. If the STA is unable to communicate with an established AP, then it instantiates a BSS with itself as the AP.

  • Publication number: 20130155898
    Abstract: A user equipment (UE) for reporting information is described. The UE includes a processor and instructions stored in memory that is in electronic communication with the processor. The UE selects a reference cell having a reference uplink-downlink (UL-DL) configuration. The UE also selects a first uplink subframe from the reference cell. The UE further selects a first subframe set from a first cell having a first UL-DL configuration. The first UL-DL configuration is different than the reference UL-DL configuration. The UE additionally determines a first set of associations between the first subframe set and the first uplink subframe. The UE further aggregates information corresponding to the reference cell and information corresponding to the first cell based on the first set of associations to produce aggregated information. The UE also reports the aggregated information on an uplink reporting cell.

  • Publication number: 20130136083
    Abstract: A method for transmitting uplink control information (UCI) using a physical uplink control channel (PUCCH) transmit diversity scheme is described. A UCI is coded with a Reed-Muller code to obtain a coded UCI. The coded UCI is mapped to quadrature phase shift keying (QPSK) symbols to obtain a mapped coded UCI. A phase shift is applied to the mapped coded UCI based on an acknowledge/negative-acknowledge (ACK/NACK) to obtain a phase shifted mapped coded UCI. The mapped coded UCI is sent using a PUCCH resource on a first antenna. The phase shifted mapped coded UCI is sent using a PUCCH resource on a second antenna.
