Abstract: The present disclosure discloses apparatuses, systems, and methods of wireless communication that use an adaptive hybrid automatic repeat request (HARQ) procedure and a multi-threaded HARQ procedure for improving HARQ buffer utilization and management. A user equipment (UE) can transmit a reset NACK to reduce the amount of HARQ buffers needed for concurrent HARQ processes. A base station can transmit different redundancy data in a HARQ retransmission depending on the types of NACK the UE transmitted. The base station can communicate with the UE using multiple light HARQ processes or threads that use less HARQ buffers than a typical HARQ procedure. Other aspects, features, and embodiments are also claimed and described.

Abstract: Disclosed are techniques to determine a position of a user equipment (UE). In an aspect, the UE receives a plurality of positioning reference signals (PRS) from a plurality of cells. The UE determines a plurality of time of arrivals (TOA) of the plurality of PRSs, and prunes the plurality of TOAs based on the plurality of PRSs. The UE then derives a time difference of arrival (TDOA) vector from the pruned TOAs. The TDOA vector includes multiple TOA related measurements of multiple cells. The UE prunes the TOAs such that the cells represented in the TDOA vector are sufficiently geographically dispersed to determine the position of the UE at least in 2D.

Abstract: Methods, systems, and devices for wireless communications are described. A mobile integrated access and backhaul (IAB) node may transmit, to an IAB supported network, an indication of IAB capability. The mobile IAB node may also indicate to the IAB supported network a mobility status associated with the mobile IAB node. The IAB supported network may conditionally determine authorization for the mobile IAB node based on the mobility status, a subscription status, or both. The IAB supported network may transmit, to the mobile IAB node, instruction to operate in an IAB mode and perform the IAB operation. The mobile IAB node may communicate with one or more devices based on the instruction.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit a capability message indicating a parameter configuration for each phase error process of a set of phase error processes of the first UE. The first UE may transmit, to a second UE, a phase error process indicator to indicate that the first UE is using a first phase error process of the set of phase error processes to generate a sidelink transmission in accordance with the parameter configuration for the first phase error process. The second UE may monitor, via a sidelink channel, for the sidelink transmission based on frequency tracking, phase tracking, time tracking, or any combination thereof being performed in accordance with the parameter configuration for the first phase error process. The first UE may transmit, via the sidelink channel, the sidelink transmission to the second UE.

Abstract: The present disclosure describes a method, an apparatus, and a computer-readable medium for a random access channel (RACH) procedure at a user equipment. For example, the method may select a two-step RACH procedure or a four-step RACH procedure at the UE based at least on RACH configuration information received from a base station or the RACH configuration information at the UE. The example method may further include transmitting, from the UE, one or more messages associated with the two-step RACH procedure or the four-step RACH procedure based on the selection.

Abstract: Aspects relate to obtaining, at a first scheduled entity, a first priority ranking of first uplink (UL) data scheduled for transmission to a scheduling entity and a first data scheduled for transmission to a second scheduled data, as well as a second priority ranking of second data scheduled for transmission to a third and fourth scheduled entity, respectively. The scheduling uses at least a portion of a sidelink resource reserved for sidelink communication for the transmissions. The scheduling of the transmissions using at least the portion of the sidelink resource are based on the first priority ranking and the second priority ranking. Various transmission cancellation and reception preemptions are transmitted from transmitting scheduled entities to other transmitting or receiving scheduled entities, respectively. Such cancellations and preemptions are based on the priority rankings, prediction of data transmission collisions and prediction of interference at receiving entities.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit a set of reference signals spanning a channel to a user equipment (UE), where each of the reference signals is associated with one of a set of transmit beams. The UE may measure a signal quality of each of the set of reference signals. In some cases, each measured signal quality may correspond to one of a set of subbands of the channel and one of the set of transmit beams. The UE may then transmit an indication of at least one signal quality associated with one of the set of subbands and one of the set of transmit beams. In some cases, the UE may indicate the at least one signal quality according to a configuration that may be indicated by the base station or selected by the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, capability signaling indicating one or more phase coherency capabilities of the UE for maintaining phase coherence across multiple uplink messages within a time interval, wherein each phase coherency capability is based on one or more channel usage characteristics associated with the time interval. The UE may receive, from the base station, a downlink message scheduling a set of uplink messages from the UE to the base station within the time interval. The UE may transmit the set of uplink messages within the time interval based on the downlink message and in accordance with at least one of the one or more phase coherency capabilities.
