Techniques and apparatus for providing hybrid automatic repeat request (HARQ) feedback for multiple physical downlink shared channel (PDSCH) transmissions are described. One example technique involves receiving downlink control information (DCI) scheduling a plurality of downlink data transmissions across a plurality of slots. The plurality of downlink data transmissions are monitored across the plurality of slots. At least one HARQ feedback scheme for acknowledging the plurality of downlink data transmissions is determined. HARQ feedback for the plurality of downlink data transmissions is provided in accordance with the at least one HARQ feedback scheme.

A data transmission method includes: determining duration indication information according to the reception status of a data frame in a multi-transmission connection transmission, the duration indication information being used to indicate the duration for which a transmission connection is continuously occupied; and sending a first confirmation message frame, the first confirmation message frame including feedback information of the reception status and the duration indication information.

Handling of HARQ and retransmission timers for sidelink DRX operations

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.

Method and apparatus for handling discontinuous reception (DRX) timer for data reception of unicast and multicast in a wireless communication system
11646829 · 2023-05-09 · ·

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.

METHODS FOR ENABLING DELAY-AWARENESS IN THE CONSTRAINED APPLICATION PROTOCOL (COAP)

A Delay Indicator parameter is contained in CoAP messages to reflect delay tolerance information. The Delay Indicator is leveraged by CoAP Clients and CoAP Servers to improve their behavior such as entering sleep mode to save energy while not violating delay requirements. A timeout mechanism for CoAP Response is enabled by a RESPONSE_Timer based on the Delay Indicator in CoAP ACK. Cancellation of CoAP Requests is enabled by leveraging the delay tolerance information as indicated by Delay Indicator.

METHOD AND APPARATUS FOR DETERMINING VALUE OF DURATION FIELD

A method, apparatus and non-transitory computer readable storage medium for determining the value of a duration field. The duration of the duration field is determined by a method that includes: receiving a first frame transmitted by a target device in a first connection; and generating an acknowledgement message frame corresponding to the first frame and to be transmitted in a second connection, where in response to the first frame including one frame, a value of a duration field in the acknowledgement message frame corresponding to the first frame is determined according to states of respective frames to be transmitted in the first connection and the second connection.

Method and apparatus for inter-user equipment coordination signaling

Methods and apparatuses for inter user equipment (UE) coordination signaling. A method of operating a UE includes determining a first set of first sidelink (SL) resources based on SL sensing and resource exclusion; selecting a first one or more SL resources within the first determined set for reservation, transmitting information about the first one or more SL resources, and receiving inter UE co-ordination information indicating whether a SL resource in the first one or more SL resources has a conflict. The method further includes transmitting on one of the first one or more SL resources, when the one SL resource does not have a conflict; and determining a second set of SL resources based on SL sensing and resource exclusion, and selecting a second one or more SL resources within the second set for transmission and reservation, when all of the first one or more SL resources have a conflict.

TELEMETRY DATA ERROR DETECTION

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.
