摘要:
This disclosure describes techniques for operating a client device to communicate with a wireless access point to validate data within a frame by comparing channel quality metrics and duration metrics to thresholds. Information received within a validity window may be treated as correctly received even if the frame fails a subsequent verification process or if reception of the frame is terminated prior to the end of the frame.

A base station and mobile station communicate using a multiple input multiple output (MIMO) communication. The base station includes a two dimensional (2D) antenna array comprising a number N of antenna elements configured in a 2D grid. The 2D antenna array is configured to communicate with at least one subscriber station. The base station also includes a controller configured to transmit N channel-state-information reference-signal (CSI-RS) antenna ports (APs) associated with each of the N antenna elements. The subscriber station includes an antenna array configured to communicate with at least one base station. The subscriber station also includes processing circuitry configured receives physical downlink shared channels (PDSCHs) from a 2D active antenna array at the and at least one base station. The 2D active antenna array includes a number N antenna elements. The processing circuitry further configured to estimate a full CSI associated with the N antenna elements.

A technique for determining whether a paging channel signal comprising one or more data units is an empty page signal as disclosed. In a method aspect, the technique involves the steps of receiving a first data unit of a paging channel signal, obtaining an empty-paging data unit of the paging channel signal as a reference data unit, correlating the reference data unit with the received first data unit, and determining whether the paging channel signal is an empty page signal based on a first correlation result. In another aspect, an apparatus for determining whether a paging channel signal comprising one or more data units is an empty page signal as disclosed. The apparatus comprises a receiving component adapted to receive a first data unit of a paging channel signal, a coding component adapted to obtain an empty-paging data unit of the paging channel signal as a reference data unit, a correlator adapted to correlate the reference data unit with the received first data unit to obtain a first correlation result, and a determinator adapted to determine whether the paging channel signal is an empty page signal based on the first correlation result.

A method for receiver processing in a 3GPP Long Term Evolution (LTE) receiver processing chain in a wireless mobile device is provided. LTE initial sub-frame transmitted from a base station is received on a LTE signalling channel. The sub-frame is received using a basic receiver. An integrity check is performed to determine if the sub-frame was demodulated and decoded correctly by the basic receiver. An advanced receiver is enabled prior to receiving an expected retransmission sub-frame based upon the integrity check failing and a hybrid-acknowledgement request (HARQ) negative acknowledgement (NAK) being sent by the wireless mobile device. The retransmission sub-frame is received using the advanced receiver. The basic receiver is enabled when the integrity check of the retransmission sub-frame passes and a acknowledgement (ACK) is by the wireless mobile device or a new data indicator (NDI) is set in a control channel indicating that the transmission is an initial transmission.

A device (102) supports error correction. A receiver (120) is configured to receive data over a communications link. A decapsulator (122) is coupled to the receiver and configured to create datagrams. A decoder (124) is coupled to the decapsulator and configured to store the datagrams in a table and to create codewords, the decoder storing the datagrams in table columns to create codewords in table rows. A user interface (126) is coupled to the decoder and configured to render images corresponding with the datagrams on the user interface. Advantages of the invention include efficient signal processing and prolonged battery life in mobile wireless devices.

Aspects of a method and system for redundancy-based decoding of voice content in a wireless local area network (WLAN) system are provided. A WLAN receiver may determine whether a decoded portion of a received packet comprises voice content and may select a redundancy-based decoder to decode a remaining portion of the packet when voice content is detected. The redundancy-based decoder may be a Viterbi decoder. The redundancy-based decoder may be selected to decode a determined number of subsequent packets or to decode subsequent packets for a determined amount of time. After decoding the remaining portion of the packet and any subsequent packets, the WLAN receiver may select a standard Viterbi decoder to decode additional received packets. The WLAN receiver may generate at least one signal to select the redundancy-based decoder and the standard Viterbi decoder.
