Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, encoded packets that are encoded using network coding. The encoded packets may be associated with source packets that represent a data set. The UE may attempt to recover the source packets from the encoded packets received from the base station. Upon failing to recover the source packets, the UE may transmit, over a sidelink channel, a message requesting sidelink assistance in recovering the source packets.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure a medium access control control element (MAC-CE) to indicate beam failure information for one or more serving cells, wherein the beam failure information is associated with at least one of a first transmit-receive point (TRP) or a second TRP of the one or more serving cells. The UE may transmit the MAC-CE to a base station via at least one serving cell. Numerous other aspects are provided.

Abstract: Aspects relate to a configurable monitoring window duration for random access. In some examples, a reduced monitoring window duration may be utilized by a user equipment (UE) to monitor for a random access message transmitted by a base station. The reduced monitoring window duration may be configured as an offset from a transmission time of a first random access message by the UE or as a reduced duration of time as measured from the transmission time of the first random access message. The configurable monitoring window duration may be associated with a random access response monitoring window, a random access contention resolution monitoring window, or a random acesss msgB response window.

Abstract: Embodiments include systems and methods for supporting for supporting retransmission in a multicast session in a Fifth Generation (5G) New Radio (NR) (5G NR) radio access network (RAN). Various embodiments may provide an enhanced multicast radio bearer (MRB) architecture leveraging Packet Data Convergence Protocol (PDCP) status reporting by wireless devices to a base station of a 5G NR RAN. Various embodiments may support multiple Radio Link Control (RLC) entities, also referred to as RLC legs, in a multicast session. One or more multicast RLC legs may be used for multicast and/or unicast transmission to wireless devices and a unicast RLC leg may be used for unicast transmission to a specific wireless device. Various embodiments may enable PDCP level retransmission of PDCP protocol data units (PDUs).

Abstract: Certain aspects of the present disclosure provide techniques for user equipment (UE) specific transmissions via multiple component carriers. A method that may be performed by a user equipment (UE) includes receiving a signal indicating a plurality of component carriers (CCs) and corresponding transmission configuration indicator states (TCI-states) for the CCs; and receiving a physical channel according to one of the corresponding TCI-states on one or more of the CCs.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may directly send small data to a disaggregated base station without performing a random access procedure. The CU-CP may provide a list of routing identifiers and corresponding data resource bearers (DRBs) to a distributed unit (DU) and the DU may transmit a connection release message to the UE. The connection release message may include the list of routing identifiers and the list of DRB identifiers. The connection release message may also include a downlink monitoring timer. The UE may identify data for an uplink transmission and a DRB associated with that data. The UE may transmit a packet with the data and the routing identifiers to a DU, which may derive downlink address information from the routing identifiers and forward the data to a CU-UP of the aggregated base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a wireless connection between the UE and a base station. The UE may identify, in an inactive state for the UE for the wireless connection, data to transmit to the base station. The UE may transmit, in the inactive state, a medium access control protocol data unit, the medium access control protocol data unit comprising both a data packet for the identified data and a request to resume an active state for the wireless connection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an average energy level radiated by the UE over a time period. The UE may determine whether the average energy level radiated by the UE over the time period exceeds a maximum permissible exposure (MPE) limit. The UE may transmit, to base station, a medium access control (MAC) control element (MAC-CE) that includes information related to a power management maximum power reduction (P-MPR) applied at the UE and/or an uplink duty cycle in effect at the UE based at least in part on the average energy level radiated by the UE over the time period exceeding the MPE limit. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to certificate based application descriptors for network slice selection. In some aspects, a user equipment (UE) may receive a first certificate associated with obtaining a network slice for executing an application. The UE may transmit, to a device, a request for the network slice with the first certificate, and receive an indication that the network slice is available to the UE for the application, based at least in part on the request. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for responding to a maximum permissible exposure (MPE) condition in uplink communications. In one aspect, a user equipment (UE) wireless device may detect an MPE condition associated with a cell in an uplink channel from the UE in the wireless communication network. The UE may configure a medium access control layer control element (MAC-CE) to indicate information related to the cell associated with the detected MPE condition and an alternative beam that avoids an MPE condition for use in uplink communications. The configured MAC-CE may include a synchronization signal/physical broadcast channel resource block indicator (SSBRI) or a channel state information resource indicator (CRI) that indicates an alternative UE panel, a feasible UE panel, Tx beam for UL transmissions or Tx beam for UL transmissions taking into account the detected MPE condition.
