A signal receiving device includes a sampling device configured to sample an input signal to output a plurality of sampling values, and an output circuit configured to output data based on the sampling values. The output circuit outputs the data by performing majority voting based on first to third sampling values of the sampling values in response to a first control signal, and outputs the data and first and second error count signals based on the first sampling value and fourth and fifth sampling values of the sampling values in response to a second control signal. The first error count signal is generated by comparing the first sampling value sampled under a reference condition with the fourth sampling value sampled under a first offset condition, and the second error count signal is generated by comparing the first sampling value with the fifth sampling value sampled under a second offset condition.

Present disclosure provides a communication apparatus comprising circuitry, which, in operation, generates a first trigger frame that includes one or more user information fields, and a transmitter, which, in operation, transmits the generated trigger frame; wherein each of the one or more user information fields indicates one of more than one hybrid automatic repeat request (HARQ) feedback types.

A Fine Time Measurement (FTM) authentication system and method include performing a FTM transaction comprising at least one FTM-ACK message pair transmitted and received via a first communication channel between two endpoints, where the at least one FTM-ACK message pair contains timestamp values of message departure time and message arrival time during the FTM transaction. At least one authenticating value indicative of timestamp values of the at least one FTM-ACK message pair arrival and departure times during the FTM transaction is then transmitted via a second communication channel. FTM timestamp values are recovered from the received at least one authenticating value, which are compared with the received FTM timestamp values. The received FTM timestamp values can be authenticated if there is a match between the recovered FTM timestamp values and the received FTM timestamp values.

When downlink data allocation is indicated in an ePDCCH, this terminal device can determine PUCCH resources to be used in notification of response signals indicating results of error detection of downlink data without imposing scheduling restrictions on future DL subframes. In this device, an extraction unit receives downlink data on multiple unit bands. A CRC unit detects errors in the downlink data. A response signal generation unit generates a response signal by using the results of error detection of the downlink data obtained by the CRC unit. The control unit arranges the response signal in the PUCCH resources corresponding to the current DL subframe.

In an example, a User Equipment (UE) receives and/or detects a transmission of data from a network. The transmission of the data is addressed to a Group Radio Network Temporary Identifier (G-RNTI) for a Hybrid Automatic Repeat Request (HARQ) process. In response to receiving and/or detecting the transmission of the data, the UE (i) starts a first HARQ Round Trip Time (RTT) timer associated with the G-RNTI for the HARQ process, and (ii) starts a second HARQ RTT timer associated with a Cell Radio Network Temporary Identifier (C-RNTI) for the HARQ process. The UE starts a multicast retransmission timer for the HARQ process in response to expiry of the first HARQ RTT timer. The UE starts a unicast retransmission timer for the HARQ process in response to expiry of the second HARQ RTT timer. The UE receives and/or detects a first retransmission of the DL data addressed to the G-RNTI for the HARQ process. In response to receiving and/or detecting the first retransmission of the data, the UE (i) stops the multicast retransmission timer, and (ii) stops the unicast retransmission timer.

A wireless device may receive configuration parameter(s) of a time alignment timer associated with a cell. The wireless device may determine to defer transmission of a HARQ feedback, associated with a transport block, from a first timing to a second timing. The wireless device may transmit, via the cell, the HARQ feedback in the second timing based on the time alignment timer running in the second timing and regardless of whether the time alignment timer is running or is not running in the first timing.

A device may receive a first telemetry data entry associated with an attribute and store a record associated with the first telemetry data entry, wherein the record identifies a first context value associated with the attribute. The device may log a first timestamp of the first telemetry data entry in a lookup table, wherein the lookup table includes a mapping of the attribute to the first context value and to the first timestamp. The device may receive a second telemetry data entry associated with the attribute and may determine, from the mapping, that the second telemetry data entry is associated with a second context value that is different from the first context value. The device may determine whether a second timestamp, of the second telemetry data entry, is before the first timestamp. The device may perform an action based on whether the second timestamp is before the first timestamp.

Certain aspects of the present disclosure provide techniques for handling acknowledgement and retransmission timers during sidelink discontinuous reception (DRX) communication. An example method by a transmitter user equipment (UE) generally includes transmitting a first repetition of a physical sidelink shared channel (PSSCH) to a receiver UE prior to entering an inactive state, while the transmitter UE is operating in a sidelink discontinuous reception (DRX) mode; returning to an active state to monitor for acknowledgment feedback from the receiver UE, wherein the return is based on a first timer relative to an end of the first repetition of the PSSCH; remaining in the active state for a duration defined by a second timer; and taking one or more actions depending on whether the transmitter UE receives acknowledgment feedback during the duration indicating failed reception of the first repetition of the PSSCH by the receiver UE.

A transmission configuration and/or configuration errors and recovery may be determined or implemented by temporal interpretation of one or more signals. A transmitter may interpret one or more signals a first way during one or more time windows and a second way during one or more other time windows. Video resolution may be indicated in a V-by-One® interface by temporal interpretation of HPD and/or CDR lock. Transmission format may be indicated before or after transmission begins. Transmitter configuration error detection and recovery may be implemented by temporal interpretation. A transmitter may transmit data in an assumed/default format. A receiver may indicate the assumed transmission format is incompatible with the receiver configuration. A receiver may indicate a compatible transmission format, for example, based on timing or pulsing transitions in a temporally repurposed signal. A transmitter may respond to the repurposed signal indication by transmitting a different (e.g., compatible) format.
