Abstract: Apparatus, methods, and computer-readable media for adjusting transmit power headroom for a secondary link while operating in an NSA mode are disclosed herein. An example method for wireless communication at a UE includes receiving a request to enter a multi-connectivity mode in which the UE is able to transmit data to a first base station via a first access link or to a second base station via a second access link. The example method also includes determining a first maximum uplink transmit power for transmissions using the first access link. Additionally, the example method includes determining a second maximum uplink transmit power for transmissions using the first access link based on uplink transmissions transmitted during an evaluation window. The example method also includes transmitting, via the first access link, at least one uplink transmission based on the second maximum uplink transmit power.

Abstract: Methods, systems, and devices for wireless communications are described. A rateless code may be used to generate n encoded packets based on a set of source packets. A modulation technique may be used to generate first symbol packets from the encoded packets. And a layered modulation technique may be used to generate coded symbol packets from the first symbol packets. The layered modulation technique may include generating a coded symbol packet from a group of first symbol packets. Different weights may be applied to the different first symbol packets included in the group of first symbol packets before the first symbol packets in the group are combined together. A receiving device may demodulate the transmitted coded symbol packets to reconstruct the group of first symbol packets, use the reconstructed group of first symbol packets to recover the encoded packets, and use the encoded packets to reconstruct the source packets.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a configuration indicating a set of encoding parameters corresponding to a constellation shaping encoding process. The UE may calculate a number of bits of a first subset of a source bit stream, and the first subset of the source bit stream may include or encompass an input to a distribution matcher. The UE may apply, to the first subset, a distribution matcher parameter based on the set of encoding parameters. The UE may calculate a number of bits of a second subset of the source bit stream, and the second subset of the source bit stream may be concatenated with an output bit stream of the distribution matcher as an input to a channel encoder. The UE may signal the source bit stream to the base station.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for sending, from an upper layer at a transmitting device to a lower layer at the transmitting device, an indication by which the lower layer determines that a packet is to be transmitted as either an initial transmission or as a retransmission. The lower layer at the transmitting device may then determine a transmission process for transmitting the packet based on the indication, and the transmitting device may transmit the packet in accordance with the transmission process. Because the lower layer may identify whether the packet is to be transmitted as either the initial transmission or the retransmission, the lower layer may adapt the transmission process to improve the chances that the packet is received by a receiving device or to limit overhead.

Abstract: Aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method generally includes receiving a request for a wireless connection from an application associated with one or more user equipment (UE) route selection policy (URSP) rules, attempting to establish the wireless connection for the application via a first subscriber identity module (SIM) according to one or more of the URSP rules associated with the application that are supported by the first SIM, and taking one or more actions to establish the wireless connection for the application via a second SIM if the attempt to establish the wireless connection for the application via the first SIM fails.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a signal - to-noise ratio (SNR) of one or more communications from a serving cell satisfies an SNR threshold after establishing a New Radio radio resource control (RRC) connection with the serving cell. The UE may transmit a measurement message to the cell based at least in part, on the determining that the SNR of the one or more communications from the serving cell satisfies the SNR threshold. The UE may receive, from the serving cell, a list of one or more neighbor cells based at least in part on the transmitting the measurement message, and establish an RRC connection to a neighbor cell on the list based at least in part on determining that a radio link failure occurred. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. One method of dynamically mapping encoded packets may include a base station identifying a set of encoded packets from a set of source packets. The base station may map subsets of the encoded packets onto a first and a second set of resources using different coding rates. In some examples, the base station may schedule one or more resources from the second set of resources for receiving feedback from one or more user equipments (UEs). In some examples, the base station may identify a second set of encoded packets from a second set of source packets and may map the second set of encoded packets onto the second set of resources and a third set of resources. A UE may recover the first or second sets of source packets based on the encoded packets transmitted by the base station.
