Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may identify a burst periodicity for communication bursts over one or more cells, such as secondary cells (SCells) in accordance with a multi-carrier communication scheme. The UE and the base station may determine a cell dormancy pattern for switching the SCells between an active state and a dormant state based on the burst periodicity. The base station and the UE may use one or more bandwidth parts (BWPs) for communications and may configure the UE to perform BWP switching over the SCell during the dormancy state switching operation. The base station and the UE may communicate the bursts while the SCells are in the active state and may switch the SCells between the active state and the dormant state based on the cell dormancy pattern.

Abstract: Methods, systems, and devices for wireless communications are described for configuring discontinuous reception (DRX) cycles within a DRX time period at a user equipment (UE). DRX configurations may provide that different DRX cycles have non-uniform cycle durations within the DRX time period. Such non-uniform cycle durations may provide DRX ON-durations that are aligned with a periodicity of downlink traffic to the UE in which the downlink traffic may be unaligned with timing boundaries used for wireless communications between the UE and a base station, such as slot boundaries or symbol boundaries.

Abstract: The present disclosure relates to methods and devices for graphics or data processing including an apparatus, e.g., a network, a server, or a client device. In some aspects, the apparatus may transmit a request for an updated FEC rate, the updated FEC rate being based on a previous FEC rate. The apparatus may also receive, based on the request for the updated FEC rate, information associated with the updated FEC rate. Additionally, the apparatus may determine the updated FEC rate based on the received information, the received information being associated with a difference between the previous FEC rate and the updated FEC rate.

Abstract: In an aspect, a UE may perform clock synchronization in accordance with a first network timing reference, such as a unicast network timing reference (UNTR) or a broadcast networking timing reference (BNTR). The UE may detect event(s) associated with a connection to a BS, which may trigger a switch between the UNTR and the BNTR for clock synchronization. In a further aspect, a communications device (e.g., UE or BS) may determine to transition a UE between the BNTR and UNTR for clock synchronization, and may perform one or more actions to facilitate the network timing reference transition.

Abstract: Methods, systems, and devices for wireless communications are described. A device may aggregate multiple data bits into a group of data bits associated with an application on the device. The device may determine quality of service parameters associated with the group of data bits. The quality of service parameters may include an error rate associated with the group of data bits, a delay budget associated with the group of data bits, timing information associated with the group of data bits, or content policy information associated with the group of data bits, or a combination thereof. The device may transmit the group of data bits to another device in the wireless communication system. The group of data bits may include group header information including an indication of the quality of service parameters.

Abstract: Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas associated with different power classes. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. The local and auxiliary antennas may be associated with different power classes, and the first device may transmit a message to a base station indicating that the first device is capable of transmitting using antennas associated with different power classes. The first device may then receive configurations from a base station of different transmit powers to transmit on the antennas associated with the different power classes, and the first device may transmit uplink signals to the base station in accordance with the different transmit power configurations.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for limiting a number of active beams available for communications between a user equipment (UE) and a base station (e.g., to limit the complexity at the UE). In one example, transmission configuration indication (TCI) states may correspond to active beams available for downlink reception that are identified based on configured quasi co-location (QCL) relationships and active QCL assumptions (i.e., the TCI states may include configured QCL relationships and QCL assumptions). Because the TCI states may include configured QCL relationships and active QCL assumptions, the number of active beams available for communications between a UE and a base station may be limited by the number of active TCI states (e.g., where the number of active TCI states may be determined based on a UE capability).

Abstract: In an access network, a base station may aggregate data packets for a user equipment (UE) into transport blocks and configure a control channel to allow the UE to sleep between control channel monitoring occasions to save power. Such data aggregation, however, may be subject to changes in traffic load and/or link quality that may result in a too low data rate or too frequent monitoring. A base station that receives data to transmit to the UE and aggregates the data according to configured control configuration parameters of the UE may determine that a link quality or a traffic load for the UE has changed. The base station may reconfigure the control channel configuration parameters of the UE based on at least one of the link quality or the traffic load in order to obtain a data rate that satisfy the traffic load for the UE.
