Abstract: A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) in a distributed cellular vehicle-to-everything environment are disclosed to determine a schedule for transmissions on subchannels of multiple frequencies based on a set of UE-specific, dynamic, and performance related metrics or criteria. The metrics may include an estimated number of users on a subchannel, a best-bandwidth fit, channel loading conditions, transmission range, and quality requirements of an application, among others. Such a schedule for transmissions on subchannels of multiple frequencies may result in either an improved capacity utilization, an improved communication quality, or both.

Abstract: Device-to-device operations are scheduled based on receive and transmit pools that may have a conflict in time domain. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for resolving time domain conflict in device-to-device communication are provided. The apparatus may compute a first block rate metric for a first device-to-device communication on a first frequency and a second block rate metric for a second device-to-device communication on a second frequency. The apparatus may detect a time-domain conflict between the first device-to-device communication on the first frequency and the second device-to-device communication on the second frequency. The apparatus may prioritize the first device-to-device communication on the first frequency and the second device-to-device communication on the second frequency based on the first block rate metric and the second block rate metric.

Abstract: Aspects relate to techniques for efficient sidelink resource reservation based on the congestion on a sidelink. A wireless communication device may transmit control information indicating a number of resources reserved for an initial transmission and at least one retransmission of a packet. In some examples, the number of resources included in the control information can be either three resources or two resources based on the congestion. For example, the number of resources included in the control information can be three resources in response to a congestion value representing the congestion on the sidelink being less than a threshold. In addition, the number of resources included in the control information can be two resources in response to the congestion value being greater than or equal to the threshold.

Abstract: Certain aspects of the present disclosure provide techniques for sidelink communications. A method that may be performed by a user equipment (UE) includes monitoring a latency between a packet arrival time from an upper layer at the UE and an over-the-air (OTA) packet transmission time. The latency is based at least in part on, a first number of subframes reserved for a sidelink synchronization signal (SLSS) and/or a second number of subframes reserved based on a configured subframe bitmap. The method includes triggering a transmit resource selection at the UE when the latency exceeds a threshold latency.

Abstract: Aspects described herein relate to configuring a primary component carrier (PCC) and at least one secondary component carrier (SCC) for transmitting uplink communications to one or more nodes of a wireless network using carrier aggregation (CA) in a first subscription of the UE, and transmitting, to at least one of the one or more nodes, a manipulated power headroom report for the at least one SCC based on a migration from an idle state to an active state in a second subscription of the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain one or more parameters associated with a dual subscriber operation of the UE that includes communicating using a first subscriber entity and a second subscriber entity. The UE may transmit one or more uplink communications via one or more of the first subscriber entity or the second subscriber entity using a coexistence management configuration that is based at least in part on the one or more parameters. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect that a first subscription, of a plurality of subscriptions associated with the UE, is associated with an active service on a first cellular network. The UE may search, for a second subscription of the plurality of subscriptions, for radio access technologies (RATs) and frequency bands that are compatible with a dual active mode of the UE. In some aspects, the UE may detect that the active service on the first cellular network has ended. Accordingly, the UE may search, for the second subscription, for RATs and frequency bands that are compatible with the dual active mode of the UE and for RATs and frequency bands that are incompatible with the dual active mode, before expiry of a timer associated with a power saving state. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a first service, having a first priority during a time interval, associated with a first subscriber identification module (SIM), and a second service, having a second priority during the time interval, associated with a second SIM of the UE, the first priority having a higher priority than the second priority. The UE may identify a first type of communication associated with the second SIM. The UE may adjust, based at least in part on the first type of communication, at least one of the first priority or the second priority during the time interval. The UE may perform a communication in accordance with the adjusted at least one of the first priority or the second priority. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform, to a first base station and via a first radio frequency (RF) chain associated with a first subscription, a first uplink transmission based at least in part on one or more of an uplink carrier aggregation capability of the UE or an uplink multiple-input multiple-output (MIMO) capability of the UE. The UE may perform, to the first base station or to a second base station, and via a second RF chain associated with a second subscription and configured to operate simultaneously with the first RF chain, a second uplink transmission based at least in part on one or more of the uplink carrier aggregation capability of the UE or the uplink MIMO capability of the UE. Numerous other aspects are described.
