Abstract: Techniques for wireless communications are described. Control information used to preschedule communication resources may be received and communications may be performed based on the control information using a prescheduling technique. A scheduling type used for the control information may be determined using configuration information, an indication included in the control information, or both. A wireless device that is prescheduled communication resources may not start or not restart an inactivity timer based on the received control information. Also, a wireless device that is prescheduled communication resources may not start a retransmission timer based on the received control information. Additionally, a wireless device that is prescheduled communication resources may also refrain from transmitting a scheduling request based on a duration until a next instance of prescheduled communication resources is expected to occur.

Abstract: Preclusive data decompression failure techniques, such as may avoid data decompression failures using predictive decompression failure indications and/or configure communication devices for data transmission recovery before reordering window timer expiration, are described. Preclusive data compression failure operation may, for example, initiate compressor memory resets conditionally according to some aspects of the present disclosure, such as using one or more trigger events to predictively indicate decompression failure. Additionally or alternatively, preclusive data compression failure operation may provide for configuring communication devices for data transmission recovery before reordering window timer expiration, such as configuration for prioritization to provide data transmission recovery before reordering window timer expiration. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications networks, a device, such as a user equipment (UE), may be configured to detect a signal blockage affecting one or more antennas of the UE. The signal blockage may be associated with the position of a body, such as a user, relative to the one or more antennas of the UE, which may include how a user places their hand on or near the device during use. The position of the body may block one or more of the antennas of the UE, causing increased signal attenuation and decreased communications performance. The UE may be configured to signal, an indication based on detecting the signal blockage.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to enhanced compression formats for data compression (e.g., uplink data compression (UDC)). A method is provided for wireless communications. The method generally includes determining one or more blocks of data in a current packet matching one or more blocks of data in one or more portions of one or more previous packets stored in a memory, compressing at least a portion of the current packet based on an enhanced compression format having reduced metadata relative to another compression format to indicate one or more of the matching blocks of data, and transmitting the compressed current packet. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that a base station, associated with a first radio access technology, is shared between one or more operator networks of a second radio access technology; and display an icon corresponding to the second radio access technology based at least in part on a particular operator network, of the one or more operator networks, being a registered operator network of the user equipment and being associated with the second radio access technology. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. A user equipment (UE) may configure a first initial set of maximum transmit powers for a first subscriber module. The UE may configure a second initial set of maximum transmit powers for a second subscriber module. The UE may configure a first maximum transmit power associated with a first connection for the first subscriber module. The UE may configure, independently of the configuration of the first maximum transmit power, a second maximum transmit power associated with the second connection. The UE may transmit based at least in part on at least one of the first maximum transmit power or the second maximum transmit power. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for packet buffering. A method that may be performed by a receiving node includes dynamically determining one or more time durations to buffer packets. The one or more time durations can be different than a time duration of a configured timer for buffering the packets. The receiving node may input one or more parameters to a machine learning algorithm and obtain, as output of the machine learning algorithm based on the input one or more parameters, one or more time durations to buffer packets. The receiving node buffers packets for the determined one or more time durations. The receiving node may use machine learning to dynamically determine the one or more time durations to buffer packet. The buffering may be at a radio link control (RLC) reassembling buffer and/or a packet data convergence protocol (PDCP) buffer.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for transmitting, to a receiving device, a first plurality of packets immediately after a first compression memory reset, transmitting, to the receiving device, a second plurality of packets different than the first plurality of packets, receiving, from the receiving device, a memory reset request associated with a second plurality of packets for a second compression memory reset, wherein the memory reset request comprises one or more recent sequence numbers of the second plurality of packets, and refraining from performing a second compression memory reset in response to determining that the at least one of the one or more recent sequence numbers is less than at least one of one or more reset sequence numbers of the first plurality of packets.

Abstract: Certain aspects of the present disclosure provide techniques for configuring a device-configured split data threshold for utilizing split data radio bearers (DRBs). A method that may be performed at a user equipment (UE) includes setting a device-configured split data threshold to a value that is less than or equal to a network-configured split data threshold value in response to the network-configured split data threshold value being greater than a first buffer threshold value associated with a data buffer of the UE, monitoring an amount of data in the data buffer, and triggering a first scheduling request (SR) associated with a first communication link and a second SR associated with a second communication link in response to the amount of data in the data buffer being greater than the device-configured split data threshold value.
