Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may wake up from a sleep mode of a discontinuous reception (DRX) cycle based on receipt of uplink data. The UE may determine if an elapsed time between a prior receipt of one or more reference signals and an uplink transmission to the base station after waking up from the sleep mode is less than a threshold time value. If the elapsed time is less than the threshold time value, the UE may transmit an uplink transmission associated with the received uplink data prior to receiving one or more reference signals that may be used to update transmission parameters for uplink transmissions. If the elapsed time is at or above the threshold value, the UE may wait to receive the one or more reference signals and update the transmission parameters prior to the uplink transmission.

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: A base station may transmit a grant to user equipment (UEs), indicating uplink resources for transmission of pending data at a UE. Uplink resources may include uplink resources associated with transmission time intervals (TTIs) and/or shortened TTIs (sTTIs). A UE may identify pending data associated with a data type (e.g., low latency data, internet traffic, etc.) and transmit a scheduling request (SR) for a grant of uplink resources. The data type of the pending data (e.g., the logic channel group identification (LCG ID) associated with a buffer status) may be indicated such that uplink resources may be granted to the UE to reduce latency. In some aspects, the SR may indicate uplink resources associated with sTTIs. Further, the UE may prioritize pending data and buffer status reports (BSRs) associated with other data within the received grant.

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 apparatuses for wireless communication are disclosed. In one aspect, a user equipment (UE) identifies a plurality of packets to send to a receiver. The packets may include radio link control (RLC) layer protocol data units (PDUs) and each may be associated with a logical channel for transmission and have a corresponding sequence number (SN). The UE may adjust a manner of assembling a transport block based at least in part on a logical channel configuration of the packets, whether the packets include RLC segments, an uplink transmission timing requirement, a number and size of transport blocks to be processed concurrently, a resource allocation associated with an uplink grant, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may run a process associated with a low latency. As such, the UE may operate in a mode to stay in a connected state with a network. The mode may include transmitting a keep alive message. Such message may be transmitted based in part on a keep alive timer with a shorter duration than a network traffic inactivity timer. If no communications occur between the UE and the network by the expiration of the keep alive timer, the UE may transmit a keep alive message to the network to maintain the connected state and reset the keep alive timer. Alternatively, if communications do occur, the UE may reset the keep alive timer. If the process is terminated, the UE may exit the mode for staying in the connected state, which may include canceling the keep alive timer.

Abstract: Systems, methods, and devices of the various embodiments provide for header extension preservation, security, authentication, and/or protocol translation for Multipath Real-Time Transport Protocol (MPRTP). Various embodiments include methods that may be implemented in a processor of a computing device for MPRTP transmission of Real-Time Transport Protocol (RTP) packets. Various embodiments may include receiving an RTP packet in which the received RTP packet may be part of an RTP stream that may be protected using secure RTP (SRTP), and applying an authentication signature to the RTP packet to authenticate an MPRTP header extension separate from a body of the RTP packet. Various embodiments may include sending and/or receiving MPRTP subflows of an MPRTP session in which a same security context may be applied across all MPRTP subflows of the MPRTP session.

Abstract: Aspects herein describe utilizing semi-persistent scheduling (SPS) resources in wireless communications. An indication to retransmit information for SPS resources can be received from an access point. It can be determined that a SPS activation for the SPS resources is not received from the access point. Based on this determination, one or more signals can be transmitted.

Abstract: In a wireless communication system, user equipment (UE) has autonomy provided by one or more set of rules to handle processing during a measurement gap. UE can ignore or use only a portion of the whole measurement gap if not needed. Thereby, an urgent need for remaining tuned to source carrier frequency can be supported, such as utilizing Random Access Channel (RACH) procedure. UE can also choose to tune to a target carrier frequency supporting timely handovers. Depending on the type of processing required (download shared channel (DL-SCH, UL-SCH, TTI bundling, RACH or SR), the UE may store requests and process the measurements during the gap or ignore the gap measurement as if there were no gaps.

Abstract: Methods, systems, and devices for wireless communications are described. In aspects, a wireless device such as a user equipment (UE) may identify an amount of acknowledgement (ACK) reduction associated with an applications processor. The amount of ACK reduction may be determined based on a communication from the applications processor, or an ACK frequency in a group of packets received from the applications processor. The UE may determine whether to modify an ACK management scheme (e.g., a transmission control protocol (TCP) ACK coalescing scheme) based at least in part on the amount of ACK reduction associated with the applications processor. The UE may modify the ACK management scheme. The UE may transmit ACKs in accordance with the modified ACK management scheme. Numerous other aspects are provided.
