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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message indicating a resource configuration for uplink and downlink transmissions. The UE may determine an uplink buffer threshold for a modem buffer of the UE based on the resource configuration. The UE may transmit, to the base station, a feedback request message requesting that the base station provide feedback for at least one previously transmitted uplink packet based on a comparison of an amount of previously transmitted uplink data and scheduled uplink data stored in the modem buffer relative to the uplink buffer threshold. The UE may receive, based on transmitting the feedback request message, a feedback response message corresponding to a first previously transmitted uplink packet of the at least one previously transmitted uplink packet.

Abstract: A method and apparatus for prioritizing data packets when stateful compression is enabled for wireless communications is disclosed. For example, the aspects include receiving a plurality of data packets scheduled in a first order for transmission. The described aspects further include prioritizing one or more data packets of the plurality of data packets as one or more prioritized data packets, each prioritized data packet being scheduled in an order for transmission different from the first order for transmission. The described aspects further include compressing one or more unprioritized data packets of the plurality of data packets into one or more compressed unprioritized data packets. The described aspects further include scheduling the one or more prioritized data packets and the one or more compressed unprioritized data packets in a second order for transmission, the second order differing from the first order.

Abstract: This disclosure provides systems, methods and apparatuses for user equipment (UE)-side and network-side mitigation of intermodulation (IM) interference, such as IM interference associated with multi-radio access technology communications. For example, the UE or a base station may detect an IM interference condition, and may perform an IM mitigation action based on detecting the IM interference condition. The UE may reduce an uplink transmit power so that IM interference on the downlink is reduced. Various base station IM mitigation actions are provided, such as suspending scheduling on a bearer, using a scheduling pattern that avoids concurrent transmission, reducing a maximum transmit power of an uplink grant of the UE, allocating resource blocks or bandwidth parts that do not overlap with an IM interference resource, changing a secondary cell group channel to a non-interfering channel, releasing a secondary cell group channel, deactivating a carrier, or changing a channel of the UE.

Abstract: In an embodiment, a UE receives a first uplink grant for a first RAT (e.g., 5G NR) and a second uplink grant for a second RAT (e.g., LTE). In one embodiment, the UE schedules an uplink transmission on the first RAT (e.g., by selectively dropping the uplink transmission on particular resource blocks) so as to manage an amount of time that is based on concurrent uplink transmissions on both the first and second RATs are performed. In another embodiment, the UE establishes a first period of time where a BSR transmitted by the UE on the first RAT is adjusted based on scheduling of concurrent uplink multi-RAT transmissions, and a second period of time where no BSR is transmitted by the UE on the first RAT based where concurrent uplink transmissions on both the first and second RATs are not permitted to be scheduled.

Abstract: Methods, systems, and devices are described for wireless communication. A user equipment (UE), for example, may determine a content size of an uncompressed buffer and a content size of a compressed buffer. The UE may then generate a buffer status report (BSR) based on the content sizes of the uncompressed buffer and the compressed buffer. Alternatively, a base station may receive a BSR based on a size of an uncompressed buffer of the UE. The base station may then receive a compressed packet from the UE and may determine a compression gain based on a size of the compressed packet and a size of a corresponding uncompressed packet. The base station may then adjust the received BSR based on the compression gain.

Abstract: Techniques are described for wireless communication. One method includes receiving, at a medium access control (MAC) entity, protocol data units (PDUs) corresponding to one or more Internet protocol (IP) flows, routing the PDUs from the MAC entity to respective radio link control (RLC) entities based on a logical channel prioritization, and forwarding the PDUs from respective RLC entities to one or more packet data convergence protocol (PDCP) entities mapped to each RLC entity. Another method includes receiving, at a protocol layer entity above an RLC layer of a transmitting device, a PDU, labeling the PDU with a unique PDCP instance identifier packet, and passing the PDU to a protocol layer entity below the PDCP layer of the transmitting device.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a wireless communication device may determine that the wireless communication device is configured to use a primary component carrier (PCC), a first secondary component carrier (SCC), and a second SCC for carrier aggregation. A primary cell may be associated with the PCC, a first secondary cell may be associated with the first SCC, and a second secondary cell may be associated with the second SCC. The first secondary cell may provide control information for the second secondary cell. The wireless communication device may monitor at least one of the first SCC or the second SCC. The wireless communication device may perform an action associated with the second secondary cell based, at least in part, on monitoring the at least one the first SCC or the second SCC.

Abstract: A user equipment (UE) and source base station may use data compression techniques for data packets sent between them. During a handover, the source base station may provide data compression context to a target base station, thus enabling the target base station to continue the data compression following the handover without having to reestablish the data compression context. The source base station may determine data compression capabilities of the UE or the target base station, or both, and may communicate the determined data compression capabilities to the UE or target base station. The source base station may identify at least one gap in a sequence of packets received from the UE, and communicate the existence of the gap to the target base station, which may request retransmission of packets associated with the gap.

Abstract: Session initiation messages may be compressed using templates for evolved data compression scheme (eDCS). One or more session initiation messages may be exchanged between various network entities, such as UEs and base stations, for purposes such as registration, call setup, and call modification, for example. Session initiation messages may include header fields which identify the caller and characteristics of the device receiving the call, and may also contain payload, which describes the audio/video codec characteristics. Many of these contents may be repeated across all user devices of the same vendor attached to the same operator and may be compressed using templates to enhance system efficiency. These templates may be known at the transmitter and receiver, and reduce the data that has to be carried over air.
