摘要： A networking device includes a packet header protect generator, a transmitter, a receiver, a decoder and router. The transmitter transmits a data packet to the receiver. The data packet includes a data packet header. The packet header protection generator is arranged to toggle selected bits of a protected portion of the data packet header and generate a data integrity signature. The receiver receives the data packet and generates a received data integrity signature. The decoder computes a locally computed data integrity signature in response to the protected portion of the received data packet header. The locally computed data integrity signature is compared with the received data integrity signature. The router selects a portion of a routing path in response to whether a data packet forwarding destination includes a decoder arranged to compute a locally computed data integrity signature.

摘要： Distributed signal field for communications within multiple user, multiple access, and/or MIMO wireless communications. In accordance with wireless communications, a signal (SIG) field employed within such packets is distributed or partitioned into at least two separate signal fields (e.g., SIG A and SIG B) that are located in different portions of the packet. A first of the SIG fields includes information that may be processed and decoded by all wireless communication devices, and a second of the SIG fields includes information that is specific to one or more particular wireless communication devices (e.g., a specific wireless communication device or a specific subset of the wireless communication devices).The precise locations of the at least first and second SIG fields within a packet may be varied, including placing a second of the SIG fields (e.g., including user-specific information) adjacent to and preceding a data field in the packet.

摘要： A method and a radio base station for interleaving control channel data to be transmitted in a telecommunications system are described. The method comprises grouping the control channel elements CCE1-CCEn into a first order of control channel symbol groups, adding symbol groups comprising dummy values or zeros to the first order of control channel symbol groups based on a number of available symbol group positions for the shared control channel, interleaving the first order of the control channel symbol groups resulting in an a second order, and mapping the second order of control channel symbol groups to the available control channel transmission resources.

摘要： An image capturing apparatus includes an input unit, a detecting unit, and a controller. The input unit continuously inputs a signal sequence. The signal sequence includes values of multiple pixels and control information. The pixels constitute an image. The control information is embedded at multiple positions according to a rule. The detecting unit detects occurrence of an error on the basis of the inputted control information. The controller interrupts the input performed by the input unit when the detected error is based on the control information embedded in a first region of the image, and continues the input when the detected error is based on the control information embedded in a second region.

摘要： A method for wirelessly transmitting data using a plurality of transmission layers includes estimating a number of data vector symbols to be allocated to one or more user data codewords during the subframe and determining a number of bits in the one or more user data codewords. The method also includes calculating a nominal number of control vector symbols to allocate to control information based, at least in part, on the estimated number of data vector symbols and the determined number of bits in the one or more user data codewords. Additionally, the method includes determining an offset value based, at least in part, on a number of layers over which the wireless terminal will be transmitting during the subframe and calculating a final number of control vector symbols by multiplying the nominal number of control vector symbols and the offset value. The method also includes mapping one or more control codewords to the final number of control vector symbols and transmitting vector symbols carrying the one or more user data codewords and the one or more control codewords over the plurality of transmission layers during the subframe.

摘要： Transmission of uplink control message for a wireless system. The uplink control message may be encoded according to one of multiple possible schemes. The choice of encoding scheme may be made based on the control message size and/or based on the available transmission resources and/or based on the detection scheme used on the receiving end. A modulation scheme may also be selected based on such factors. CDM may be used for certain control messages. Block code encoding, such as Reed-Muller encoding may be used for certain control messages. Different transmission resources may be allocated for different control message uses. The encoding specifics may be selected to obtain a certain hamming distance and/or size of the encoded message or based on other factors.
