Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and another device (e.g., another UE) may transmit messages on a shared channel accessed in a half-duplex manner (e.g., within a vehicle-to-everything (V2X) network). The UE and the other device may transmit messages on semi-persistently scheduled (SPS) resources. A message of the UE and a transmission of the other device may collide (e.g., be transmitted in the same subframe). The UE may employ muting and measuring, in which the UE may refrain from transmitting on a SPS resource and may detect the transmission of the other device. Upon detection of other transmissions, the UE may perform resource reselection. During resource selection or resource reselection, the UE may exclude an entire subframe of candidate resources if one of the candidate resources of the subframe is mapped to a resource associated with a transmission from another device.

Abstract: Methods, systems, and devices for wireless communication are described. The described techniques allow a user equipment (UE) to conserve power after transitioning from one coverage mode to another coverage mode based on power consumption estimates. The UE may make a determination on whether to modify its current extended discontinuous reception (eDRX) values by either triggering an unscheduled timing update or waiting for a scheduled timing update. For instance, the UE may estimate power consumption based on current eDRX values and the time remaining until a scheduled timing update procedure and compare this estimate to power consumption estimate based on modified eDRX values and the amount of power consumed to perform an unscheduled timing update procedure. Based on the comparison, the UE may update its eDRX values through an unscheduled TAU or through the regularly scheduled TAU procedure.

Abstract: A method, an apparatus, and a non-transitory computer readable medium for receiving data and one or more redundant equivalent versions of the data from a remote user equipment (UE), buffering the data and the one or more redundant equivalent versions of the data, transmitting the data to a base station, receiving at least one negative acknowledgement, relating to the data, from the base station indicating an unsuccessful reception of the data; and transmitting, in response to receiving the at least one negative acknowledgement, at least one of the one or more redundant equivalent versions of the data to the base station.

Abstract: Aspects of the present disclosure provide techniques to enable enhanced machine type communication (s) (eMTC) and/or narrowband Internet-of-Things (NB-IoT) devices to transition to idle mode after releasing a connection, such as a radio resource control (RRC) connection, more quickly than with previously known techniques. An example method includes determining, based on an indication received in a narrowband signal on a narrowband region of a bandwidth comprising a plurality of narrowband regions, whether to wait for a delay period, determined based on a configuration received from a network entity, before releasing a radio resource control (RRC) connection and releasing the RRC connection at a time in accordance with the determination.

Abstract: Methods and apparatus for selection of radio access technology (RAT) based on device usage patterns are provided. A User Equipment (UE) obtains information relating to one or more Quality of Service (QoS) metrics for communication of data by the UE. The UE designates a Radio Access Technology (RAT) from a plurality of available RATs as a preferred RAT for the communication, based on the obtained information.

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.
