Abstract: Full-duplex communication techniques are described. Some aspects may utilize full-duplex-slot formats, such as may be provided in addition to or in the alternative to uplink, downlink, and flexible slot formats. A full-duplex slot implemented in accordance with a full-duplex-slot format provides a slot in which the frequency band may be used for both uplink and downlink transmissions. Downlink and/or uplink transmissions of a full-duplex slot may occur in overlapping frequency bands or in adjacent frequency bands. A first wireless device may transmit slot signaling comprising one or more full-duplex-slot-indicator parameters. A second wireless device may base one or more full-duplex slot configuration determinations on a full-duplex-slot configuration. The second wireless device may apply one or more full-duplex-slot-indicator-parameter rules with respect to full-duplex-slot-indicator parameters for determining a full-duplex-slot format. Other aspects and features are also claimed and described.

Abstract: A user equipment (UE) may use a resource configuration to determine whether to transmit or receive on a particular sub-band during a given communication period (e.g., a time slot or a symbol duration). In some examples, a network entity provides a bit map to a UE where the bit map indicates how sub-bands for a given communication period are allocated for full-duplex transmissions. The UE may then determine, based on the bit map, whether to transmit or receive on a particular sub-band. In some examples, a network entity provides a resource configuration to a UE where the resource configuration indicates how half-duplex transmissions and full-duplex transmissions are configured over a period of time. In this case, the UE may be configured by a defined rule to determine, based on the resource configuration, whether to transmit or receive on a particular sub-band.

Abstract: A transmitter at a first location transmits the message at a symbol rate of the reference clock using a first carrier, whose phase is locked to a phase of the reference clock and whose frequency is a first integer times a frequency of the reference clock. It also transmits the message at the symbol rate of the reference clock using a second carrier, whose phase is locked to the phase of the reference clock and whose frequency is a second integer times the frequency of the reference clock. The second integer is unequal to the first integer. A receiver at a second location receives the message at the first carrier and at the second carrier, and accurately determines a time of a first phase difference between the first carrier and the second carrier. It determines a time of receiving the message from the time of the first phase difference.

Abstract: An application running on a user equipment determines a retransmission request indication for a packet that was not successfully decoded based on a criticality, or quality-of-service requirement, from a retransmission request configuration, which may correspond to a traffic flow managed by the user equipment. The retransmission request indication may correspond to a criteria range in a retransmission request configuration. The application at the user equipment may determine a latency criteria range to use to determine a retransmission request indication based on a sensed degradation of user experience corresponding to the traffic flow. The user equipment may transmit the retransmission request indication to a network node, which may prioritize scheduling of retransmission of the failed-decoding packet or transmission of new packets according to a priority indicated in the retransmission request indication.

Abstract: A method and a communication apparatus for determining a timing advance. A downlink signal is received from a network device. A first reference moment of a signal period of the downlink signal is determined, where the first reference moment includes a start receiving moment of the signal period.

A timing advance is determined based on the start receiving moment and the start sending moment, and an uplink signal is sent based on the timing advance.
