Abstract: Methods systems and devices for wireless communications are described. One or more multiple access-capable user equipments (UEs) may be grouped together for transmitting uplink multiple access communications to a base station, where the UEs may be assigned to the group based on similar capabilities or service requirements. The UE may receive configuration information based at least in part on the group to which the UE has been assigned. When assigned to a group, the UEs may also receive a group-specific scrambling code for the uplink multiple access communications, a group-specific power control for the uplink multiple access communications, time and frequency resources to be used for the uplink multiple access communications specific to the group, or a combination thereof. Additionally, the specific time and frequency resources may be defined by multiple access resource units.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may receive, from a user equipment (UE), a first random access message of a two-step random access procedure. In some examples, the first random access message may be transmitted by the UE based on one or more cell-specific transmission parameters or cell-specific transmission schemes. The base station may transmit, to the UE, a second random access response message of the two-step random access procedure in response to the first random access message. The second random access response message being transmitted based on one or more cell-specific transmission parameters or cell-specific transmission schemes. Accordingly, the base station and the UE may establish a connection with the UE based on the first random access message and the second random access response message, or the base station can indicate to the UE to return to an inactive mode or idle state.

Abstract: To facilitate operations of a low-power UE with high RF sensitivity, methods, apparatuses, and computer-readable medium are provided. An example method includes receiving, from a base station or a second UE, a reservation reserving a set of time-domain resources and a set of frequency domain resources around a WUS for a low-power UE. The example method further includes refraining from transmitting in the reserved resources.

Abstract: A user equipment (UE) receives one or more timing advance commands from a non-terrestrial network (NTN). The UE resets, after a GNSS fix, a cumulative timing advance value based on the one or more timing advance commands from the NTN and transmits an uplink transmission with a timing advance based on a self-estimated delay and the cumulative timing advance value. The UE may adjust a self-estimated delay based on at least one GNSS fix. The UE may transmit an uplink transmission with a timing advance based on the adjusted self-estimated delay and a cumulative timing advance value based on the one or more timing advance commands from the NTN.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a synchronization signal/physical broadcast channel (SS/PBCH) block index, associated with an SS/PBCH block, based at least in part on a set of bits included in a payload of a PBCH of the SS/PBCH block, a demodulation reference signal (DMRS) sequence included in the PBCH, a scrambling sequence associated with the PBCH, or an interleaving associated with the PBCH. Numerous other aspects are described.

Abstract: A user equipment may be configured to limiting transmit power for frequency domain division for high power user equipment. In some aspects, the user equipment may determine a UE context is interference limited or noise limited based on comparing a measurement value to a threshold value, set a maximum transmit power based on the UE context, and transmit, during a time period associated with a downlink (DL) grant, an uplink (UL) transmission at the maximum transmit power.

Abstract: RACH occasion repetition and PRACH format selection in an NTN are disclosed. The base station may determine, based on at least one beam, a first PRACH configuration for at least one first UE and a second PRACH configuration for at least one second UE. The base station may transmit, to at least one of the at least one first UE or the at least one second UE, an indication of the first PRACH configuration and the second PRACH configuration. The UE, based on whether it is a first UE or a second UE, may select, based on the received indication, the first PRACH configuration or the second PRACH configuration for at least one beam. The UE may initiate, via the at least one beam, a RACH procedure for the selected first PRACH configuration or the selected second PRACH configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a first base station associated with a first operator, a broadcast transmission conveying a first portion of a communication; and may receive, without triggering a retransmission of the broadcast transmission, a second portion of the communication via a unicast transmission from a second base station associated with a second operator. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) message associated with scheduling uplink transmissions from the UE on a set of component carriers (CCs). The DCI message may indicate that a first uplink channel on a first CC of the set of CCs at least partially overlaps in time with a second uplink channel on a second CC of the set of CCs. The UE may multiplex, based on the first uplink channel at least partially overlapping in time with the second uplink channel, uplink control information (UCI) with an uplink data transmission on the first CC or the second CC. The UE may transmit the UCI and the uplink data transmission multiplexed on the first CC or the second CC based at least in part on the DCI message.
