摘要： Provided is a wireless communication device. A PHICH reception unit determines whether a received signal in a PHICH region is an ACK signal or a NACK signal. When doing so, the PHICH reception unit does not receive a PHICH in a subframe in which a terminal monitors an E-PDCCH. A control signal reception unit outputs a retransmission prompting signal to a signal allocation unit when the signal outputted from the PHICH reception unit is a NACK signal and when a UL grant was not detected. Meanwhile, when a UL grant was detected, the control signal reception unit outputs the detected UL grant to the signal allocation unit. The signal allocation unit maps the transmission signal in accordance with the retransmission prompting signal and the UL grant and transmits the transmission signal from a wireless transmission unit.

摘要： The disclosed embodiments process a message by determining location information for a device originating the message. In some aspects, a method includes obtaining location information for each of a first set of stations, receiving, from each station in the first set of stations and a second set of stations, a list identifying access points of the first and second set of stations from which signals have been received by the respective station, receiving a message originating from the originating station, the message received via a first access point (AP) included in the second set of stations, determining a location for the first access point based on the location information for the first set of stations and the received lists, determining a location of the originating station based on the determined location of the first access point, and processing the message based on the determined location of the originating station.

摘要： As many applications, such as wireless headsets used with cellular phones, require mostly error free data to accurately reproduce a telephone conversation, uncorrected erroneous data packets may impact a perceived quality of a given application. The error correction techniques of the present disclosure promote error-correction in communication systems that lack FEC with respect to one or more portions of a data packet. The techniques therefore provide error correction for the entire packet, including those portions not protected by any imbedded error correction mechanism. As a result, data communications over noisy communication mediums may be improved as the techniques may reduce bit error rates, and increase the sensitivity of the receiving device such that the transmission power of a data packet may be reduced. For voice packets or other streaming data packets, the techniques promote improved audio quality over systems that do not employ the techniques described in the present disclosure.

摘要： An example access point may include a memory and a processor executing instructions from the memory to receive an instruction to start a scan on a different wireless communication channel than an operating channel of the access point; transmit a Clear To Send-to-self frame on the operating channel of the access point, to notify client devices associated with the AP and at least a neighboring AP that the operating channel is busy, wherein the control frame includes a basic service set color associated with the access point; scan on the different wireless communication channel subsequent to transmitting the Clear To Send-to-self frame; and defer a subsequent data transmission received from the client devices in response to the data transmission including the basic service set color associated with the access point.

摘要： A payment reader and a merchant device may communicate over a wireless connection. Reliable and unreliable packets may be transmitted over a single messaging path. Each of a plurality of unreliable packet may include a data payload and a packet identifier. The unreliable packets and a reliable packet may be transmitted over the single messaging path during a first connection event. A response to the reliable packet may be received during the second event and may include a received packet listing. If the received packet listing indicates that any of the unreliable packets were not received, any unreliable packet that was not received may be retransmitted.

摘要： Embodiments of a UE and methods for D2D communication are generally described herein. The UE may transmit, as part of an in-network communication session, a D2D discovery status message. The D2D discovery status message may indicate an initiation or termination of a D2D discovery operation at the UE and may indicate if the UE is announcing or monitoring as part of the D2D discovery operation. The D2D discovery operation may be at least partly for configuring a D2D communication session between the UE and one or more other UEs. The UE may transmit, as part of the D2D discovery operation, a D2D discovery signal for reception at one or more other UEs. The UE may transmit and receive D2D packets over a direct link to a second UE as part of the D2D communication session.

摘要： [Problem] To avoid the occurrence of a “DTX-ACK” error or “DTX-NACK” error when a terminal has failed to receive uplink control information. [Solution] A base station (20) of a wireless communication system wherein packet retransmission control is performed by means of a hybrid automatic repeat request (HARQ) is equipped with: a physical uplink shared channel (PUSCH) reception processing unit (104) that, when the transmission timing of HARQ information from a terminal (10) coincides with the transmission timing of a PUSCH transmitted from the terminal (10), receives the HARQ information from the PUSCH and performs a cyclic redundancy check (CRC) on a packet included in the PUSCH; and an HARQ information check unit (105) that performs HARQ-based confirmation of reception at the terminal (10) by receiving the HARQ information checked by the PUSCH reception processing unit (104) and the CRC result.

摘要： Provided is a radio communication device which can make Acknowledgement (ACK) reception quality and Negative Acknowledgement (NACK) reception quality to be equal to each other. The device includes: a scrambling unit (214) which multiplies a response signal after modulated, by a scrambling code “1” or “e−j(π/2)” so as to rotate a constellation for each of response signals on a cyclic shift axis; a spread unit (215) which performs a primary spread of the response signal by using a Zero Auto Correlation (ZAC) sequence set by a control unit (209); and a spread unit (218) which performs a secondary spread of the response signal after subjected to the primary spread, by using a block-wise spread code sequence set by the control unit (209).
