Abstract: A user equipment (UE) may initiate a random access (RACH) procedure using an uplink resource selected based on a corresponding received synchronization signal block. The UE may detect a random access procedure trigger. The UE may configure a selection threshold time. The selection threshold time may be based at least in part on a latency requirement of the UE. The UE may select a synchronization signal block having a corresponding uplink resource within the selection threshold time. The synchronization signal block and corresponding uplink resource satisfy one or more parameters or conditions. The UE may transmit a random access preamble on the corresponding uplink resource.

Abstract: In an example, a method of wireless communication of a base station may include assigning, by the base station, one or more resources to a group comprising a plurality of UEs that includes a first UE. The method may include receiving, by the base station from the first UE, a message on the one or more assigned resources. The message may include a cyclic redundancy check (CRC) scrambled with a group identifier for the group comprising the plurality of UEs. The message may include an indication of a UE identifier for the first UE within the group. The message may include a DMRS, where the indication of the UE identifier is represented by a sequence of the DMRS.

Abstract: NPRACH suffers from false alarms in which a base station detects and cannot distinguish an NPRACH signal that is intended for a different base station. An NPRACH may include a cell specific frequency shift pattern over repetitions and/or a repetition level scrambling sequence that enables a base station to more accurately detect NPRACH. An apparatus generates an NPRACH signal comprising multiple repetitions, wherein each repetition comprises multiple symbol groups. The apparatus may apply a different frequency shift between repetitions of the NPRACH signal. The frequency shift may comprise a cell specific random frequency shift pattern applied over each repetition. The apparatus may apply a repetition level scrambling sequence to the NPRACH signal, wherein a single scrambling sequence is applied to a set of repetitions comprised in the NPRACH signal. The apparatus transmits the NPRACH to a serving cell.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for linear precoding in full-dimensional MIMO (FD-MIMO) systems. According to aspects, an eNB may compress a larger number of antenna elements to a smaller number of antenna ports. The eNB may use a port precoding matrix to transmit reference signals to a UE, receive feedback regarding CSI based on the reference signals, and transmit data to the UE, based on a mapping of multiple data layers and mapping of antenna ports to the physical antenna elements. Further, aspects include performing elevation beamforming by dynamically forming one or more vertical sectors based on UE feedback in the elevation domain.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first sidelink device may obtain an absolute time. The first sidelink device may perform a ranging session on a first sidelink connection with a second sidelink device to obtain a first propagation delay between the first sidelink device and the second sidelink device. The first device may generate a first corrected absolute time for the second sidelink device based at least in part on the absolute time and the first propagation delay such that the second sidelink device will also have the absolute time. The first sidelink device may transmit the first corrected absolute time to the second sidelink device in a first message on the first sidelink connection. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a remote user equipment (UE) may generate a measurement report for discovery that includes a serving relay UE source Layer 2 (L2) identifier (ID), of a serving relay UE that serves the remote UE, and a candidate relay UE source L2 ID, for each candidate relay UE of a set of candidate relay UEs. The UE may transmit the measurement report. Numerous other aspects are described.

Abstract: Methods, apparatuses, and computer-readable medium are provided. An example method may include transmitting, to one or more UEs including a second UE, a sidelink discovery message for a communication with a third UE. The example method may further include receiving, from the one or more UEs, a sidelink discovery response including information about a path with the third UE. The example method may further include establishing a sidelink connection with the second UE to relay the communication from the first UE to the third UE based, at least in part, on the information about the path between the second UE and the third UE.

Abstract: A method, apparatus, and computer-readable storage medium for wireless communication at a first user equipment (UE) is provided. The UE receives an indication of one or more timers associated with a radio resource control (RRC) connection procedure with a base station via a relay. The UE transmits a request associated with an RRC connection to a second UE to be relayed to the base station and monitors for a response from the base station based on the one or more timers associated with the RRC connection procedure via the second UE as the relay.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that the UE is in communication with a first slice of a network via a first control entity at the UE, and may determine that the UE is to further communicate with a second slice of the network. The UE may transmit a control message associated with the first control entity, where the control message may include a request pertaining to communications with the second slice. The UE may receive, in response to the control message and at the first control entity, a reconfiguration message indicating a configuration for using the second slice. The UE may communicate with the second slice of the network based on the configuration.

Abstract: Certain aspects of the present disclosure provide techniques for improved sidelink discovery communication. An example method performed by a user equipment (UE) generally includes deciding, when a conflict occurs between a sidelink discovery message and at least one other transmission in a transmission period, whether to transmit the sidelink discovery message or the at least one other transmission based, at least in part, on a priority of the sidelink discovery message; and transmitting the sidelink discovery message or the at least one other transmission in the transmission period, in accordance with the decision. Another example method by a UE generally includes signaling a capability of the UE to simultaneously receive, during a reception period, on a downlink and a sidelink; and receiving on the downlink while also receiving on the sidelink, in accordance with the capability.
