Abstract: A user equipment (UE) (e.g., an enhanced machine type communication (EMTC) UE) may identify several narrowbands associated with eMTC protocol based on a system bandwidth of a New Radio (NR) carrier. A base station may transmit an indication of a set of valid narrowbands for eMTC (e.g., based on coexistence considerations between eMTC and NR) to the UE. The base station may further transmit a frequency hopping pattern to the UE (e.g., associated with narrowbands within the set of valid narrowbands), and transmit one or more downlink transmissions according to the frequency hopping pattern. Additionally or alternatively, a base station may identify a subcarrier offset and/or resource block offset between resources (e.g., a resource grid) used for eMTC protocol and resources used for NR. The base station may transmit a frequency alignment parameter to the UE, and the UE may align narrowbands for eMTC accordingly.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining a current status of cellular vehicle to everything (CV2X) traffic and then allocating application processor resources for a CV2X call based on the current status of the CV2X traffic. The allocating may include reserving the application processor resources for the CV2X call when the CV2X traffic is active and releasing the reserved application processor resources when there is no CV2X traffic.

For example, a wireless communications system may support New Radio (NR) cellular-vehicle to everything (C-V2X) communication. In some examples, a user equipment (UE) may receive a sidelink control channel for a sidelink transmission on a first set of symbols of a time slot (e.g., the first two or three symbols of a time slot). The UE may decode the sidelink control channel and disable one or more radio frequency (RF) components associated with processing the sidelink transmission on a second set of symbols of the time slot based on decoding the sidelink control channel. For example, the UE may disable one or more RF components if the UE determines the sidelink control channel is decoded unsuccessfully.

Generally, the described techniques provide for efficiently performing and reporting reference signal received power (RSRP) measurements. In particular, the techniques described herein may allow a user equipment (UE) to efficiently identify reference signals on which to perform RSRP measurements (e.g., based on signaling from a base station), identify when to report RSRP measurements (e.g., aperiodically, periodically, or semi-persistently), and identify a channel on which to report RSRP measurements (e.g., a sidelink channel or an uplink channel). In addition, the techniques described herein may also allow a UE to efficiently identify open loop parameters to use to determine an appropriate transmit power for transmitting to another UE over a sidelink.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently scheduling downlink data transmissions and flow control feedback for the downlink data transmissions to allow for efficient pipelining at a user equipment (UE). In one aspect, a UE and a base station may follow preconfigured rules for facilitating downlink data transmissions while avoiding confusion (e.g., confusion due to being scheduled to report flow control feedback for downlink data transmissions in a different order from which the downlink data transmissions are received). In another aspect, the UE may be configured to report flow control feedback for a downlink data transmission in a next uplink control channel to avoid confusion (e.g., in the event that the UE misses downlink control information (DCI) used to indicate the timing for reporting flow control feedback for a downlink data transmission).

Abstract: Methods, systems, and devices for wireless communications are described that provide for sidelink preemption. In some examples, a base station may transmit a preemption indication to instruct a user equipment (UE) to refrain from transmitting on a set of resources. In some examples, the preemption indication may be transmitted to a UE through a relay UE, which may adjust timing or resources of the preemption indication, include receipt or generation info of the preemption indication, or refrain from transmitting the preemption indication. Additionally, or alternatively, one or more sidelink UEs may infer a preemption indication from an uplink cancellation indication, and may refrain from performing sidelink communications based on the preemption indication.

The UE may transmit a buffer status report (BSR) using the contention-free PUR. The first communication may provide an indication of one or more physical layer parameters associated with the second uplink communication.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a base station, control signaling indicating a set of resources of a sidelink channel available for sidelink communication with a second UE. The first UE may receive a sidelink preemption indication indicating that at least a first resource from the set of resources is preempted. The first UE may communicate a sidelink transmission over the sidelink channel with the second UE based on the sidelink preemption indication. In some cases, the first UE may determine whether the SPI satisfies one or more thresholds and the first UE may communicate the sidelink transmission, or refrain from communicating the sidelink transmission, based on determining whether the SPI satisfies the one or more thresholds.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may activate or release one or more semi-persistent scheduling (SPS) configurations for group-common downlink shared channels based on signaling from a base station. For example, the UE may receive downlink control information (DCI) from the base station that includes a feedback process field, where a value of the feedback process field indicates at least one of one or more SPS configurations is to be activated. In some examples, the base station may transmit the DCI in a group-common downlink control channel or in a UE-specific downlink control channel. Additionally, the base station may transmit a deactivation message to the UE to indicate for the UE to release one or more activated SPS configurations, where the deactivation message is transmitted in a group-common downlink control channel or a UE-specific downlink control channel.
