A disclosure of this specification provides a method performed by a wireless device for determining a transport block size (TBS). The method may include the steps of determining a number of resource elements (REs) within a slot, calculating a value related to the TBS, based on the determined number of REs and a code rate, comparing the calculated value with a pre-determined threshold value, determining the TBS according to the comparison, wherein, if the calculated value is smaller than or equal to the pre-determined threshold value, the TBS may be determined using a predetermined table.

A communication system is a communication system that includes first and second information processing devices. The first information processing device performs control such that a signal (which is a signal having backward compatibility) serving as an index by which the second information processing device receiving a frame stops the reception of the frame is transmitted to the second information processing device. The second information processing device performs control such that the reception of the frame is stopped based on the signal (which is a signal having backward compatibility) serving as an index by which reception of the frame is stopped when the frame transmitted from the first information processing device is received.

The present invention relates to a method for receiving control information within a subframe of a multi-carrier communication system supporting carrier aggregation, the method comprising the following steps performed at a receiving node: performing a blind detection for the control information within a search space by means of a first search pattern, wherein the first search pattern is one of a plurality of search patterns, each of the plurality of search patterns comprising a plurality of candidates distributed on any of a plurality of aggregation levels, and wherein the plurality of search patterns further comprises a second search pattern whose candidates are non-overlapping the candidates of the first search pattern on the same aggregation levels.

A word boundary detection method includes receiving a data stream from a data channel of a high definition multimedia interface (HDMI), and performing pattern matching upon the data stream to identify a word boundary between two consecutive codewords transmitted via the data stream. Known codewords of scrambled control vectors are involved in the pattern matching.

A network node device of a communication network comprises physical (PHY) layer circuity configured to transmit and receive data packets via a communication network; and processing circuitry connected to the PRY layer circuitry. The processing circuitry is configured to encode a data packet for sending according to a first communication protocol for sending to a second network node during a specified communication time slot, initiate resending of the data packet when the second network node does not respond during a specified acknowledge time slot, and encode the data packet according to a second communication protocol for sending to the second network node for a last retry attempt of a finite number of retry attempts, wherein the time to send the data packet formatted in the second communication protocol extends into the specified acknowledge time slot.

Provided are systems and methods for convergent error vector indexing and retransmission in wireless data verifications. An example method includes transmitting a network packet to a receiver; receiving a further network packet being a copy of the network packet as received by the receiver, determining, based on the network packet and the further network packet, an error vector and locations of errors in the further network packet; sending, to the receiver, a first indexing packet including the locations of the errors; receiving a second indexing packet being a copy of the first indexing packet as received by the receiver; determining, based on the error vector and the second indexing packet, the locations of the errors in the second indexing packet; and sending a third indexing packet including the locations of the errors to the receiver, where the receiver corrects the further network packet using the third indexing packet.

A first electronic device may share information about a received packet with a second electronic device to obtain first information indicating whether the first electronic device and the second electronic device each receive a data packet from the third electronic device during a first time period, in case that the first information indicates that the first electronic device and the second electronic device each fail to receive the data packet during the first time period, transmit a first response packet indicating a negative acknowledgment (NACK) to the third electronic device, and share the information about the received packet with the second electronic device to obtain second information indicating whether the first electronic device and the second electronic device each receive the data packet retransmitted from the third electronic device during a second time period after the first time period.

A transmission apparatus includes a transmission signal generator which, in operation, generates a transmission signal having an aggregate physical layer protocol data unit (PPDU) that includes a legacy preamble, a legacy header, a non-legacy preamble, a plurality of non-legacy headers and a plurality of data fields; and a transmitter which, in operation, transmits the generated transmission signal, wherein the legacy preamble, the legacy header and the plurality of non-legacy headers are transmitted using a standard bandwidth, the non-legacy preamble and the plurality of data fields are transmitted using a variable bandwidth that is larger than the standard bandwidth and wherein a plurality of sets of each of the plurality of non-legacy headers and each of the plurality of data fields are transmitted sequentially in a time domain.

A network node device of a communication network comprises physical (PHY) layer circuitry configured to transmit and receive data packets via a communication network; and processing circuitry connected to the PHY layer circuitry. The processing circuitry is configured to encode a data packet for sending according to a first communication protocol for sending to a second network node during a specified communication time slot, initiate resending of the data packet when the second network node does not respond during a specified acknowledge time slot, and encode the data packet according to a second communication protocol for sending to the second network node for a last retry attempt of a finite number of retry attempts, wherein the time to send the data packet formatted in the second communication protocol extends into the specified acknowledge time slot.
