  • Publication number: 20240215046
    Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may transmit an expiration indication to a receiving device as part of a scheduling message for a transport block. The expiration indication may provide information related to an expiration time for the transport block. If the expiration time is reached prior to successful reception by a receiving device, the receiving device may assume that the transport block has expired and may refrain from transmitting a retransmission grant, or may empty a hybrid automatic repeat request (HARQ) buffer associated with the transport block. If the transmitting device fails to successfully receive an indication from the receiving device of a successful reception of the transport block prior to the expiration period, the transmitting device may also assume that the transport block has expired.

  • Patent number: 11979912
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use easily detectable transmission parameters to infer difficult-to-detect parameters for communications with a base station. For example, the base station may provide the UE with multiple sets of transmission parameters, and the UE 115 may choose from among these sets of transmission parameters for the communications. In some cases, the UE may be configured with a reference set of transmission parameters, receive one or more transmission parameters that are different relative to the reference set of transmission parameters, and then determine to use the different transmission parameters for the communications. Additionally or alternatively, the multiple sets of transmission parameters may be specified for a certain uplink message (e.g., random access channel messages), where the UE selects the transmission parameter set based on one or more characteristics of the uplink message.

  • Patent number: 11950273
    Abstract: Methods, systems, and devices for wireless communication are described. In one example, a base station may dynamically configure a user equipment (UE) to monitor or avoid monitoring for a preemption indication. Accordingly, the UE may have a lower chance of monitoring for a preemption indication when it is unlikely that an uplink or downlink transmission will be preempted. In another example, a base station may transmit a control message indicating whether future indications received from the base station are to be interpreted as preemption indications or permission indications. Accordingly, the base station may choose to use either preemption indications or permission indications (e.g., based on the probability of collisions between mobile broadband (MBB) and low latency transmissions) to facilitate MBB and low latency communication multiplexing with limited signaling.

  • Publication number: 20240090076
    Abstract: Methods, systems, and devices for wireless communications are described. A network entity may account for jitter in communications with a user equipment (UE) by adjusting connected mode discontinuous reception (CDRX) configuration parameters for the UE based on estimated downlink traffic arrival times. For a downlink traffic burst, the network entity may estimate a traffic arrival offset based on determining a traffic periodicity, an estimated arrival time associated with one or more packets of a traffic burst, and at least one jitter parameter. The jitter parameter may represent an uncertainty in the arrival time of the traffic burst. The network entity may select a CDRX offset value based on the estimated traffic arrival offset. The network entity may transmit (e.g., to a UE, such as an extended reality (XR) device) a message indicating the CDRX offset value, for example, as part of a CDRX configuration.
