Methods, systems, and devices for wireless communications are described. A first user equipment (UE), such as a pedestrian UE, may perform a discovery procedure with a second UE in a vehicle-to-everything (V2X) wireless communications environment that includes multiple other UEs in addition to the first UE and the second UE. The second UE may, for example, be a roadside UE configured to aggregate V2X messages for the first UE. The first UE may determine, based on performing the discovery procedure, a schedule for the first UE to use to receive bundled V2X messages from the second UE. The first UE may receive, from the second UE based on the determined schedule, a message indicating bundled information from multiple V2X messages received at the second UE from the multiple UEs.

Systems and methods for providing power savings at a wireless communications device in coordination with early measurement reporting are disclosed. In one embodiment, a method performed by a wireless communication device comprises obtaining first information for determining whether the wireless communication device meets criteria for entering into one or more relaxed measurement modes and obtaining second information about whether the wireless communication device is configured with early measurement reporting. The method further comprises selecting a measurement mode from a set of measurement modes comprising the one or more relaxed measurement modes and a normal measurement mode. In one embodiment, selecting the measurement mode comprises determining, based on the first information, whether the wireless communication device meets the criteria for entering into the one or more relaxed measurement modes and selecting one of the set of measurement modes based on upon results of the determining and based on the second information.

Methods, systems, and devices for wireless communications are described that support techniques for wireless communications using preconfigured uplink resources. Generally, the described techniques provide for enhancement of communication features including frequency hopping, an uplink control channel, coverage enhancement, timing advance, uplink power control, reconfiguration, a downlink control channel, a downlink data channel, retransmissions, or subcarrier spacing for a UE in idle mode. The UE may receive an uplink resource configuration for uplink communications in idle mode, the uplink resource configuration comprising an indicator associated with allocated resources for the uplink communications in idle mode and a set of parameters. The UE may transmit, while in idle mode, a first uplink transmission associated with a transport block on the allocated resources and according to one or more of the parameters, and monitor for a response to the first uplink transmission.

Introduced here are techniques for reducing the average throughout of a baseband (BB)-radio frequency (RF) interface. The techniques include removing excess bits from a received signal based on the signal to noise ratio (SNR), rotating the reduced signal to direct current frequency, and applying a coding scheme to further compress the signal. After compression, the signal can be transmitted from one chip to another. The receiving chip can retrieve the signal by rotating the signal to its original frequency and retrieving the removed bits based uplink gain information. By doing so, the number of bits being transmitted is reduced and thus, the average throughput of the BB-RF interface is also reduced.

Disclosed are methods, systems and devices for obtaining a measurement of a range between two devices. For example, wireless stations may obtain a measurement of range between the wireless stations based, at least in part, on an exchange messages such as fine timing measurement (FTM) messages. In a particular implementation, FTM messages may be received at a transceiver device in a burst of FTM messages from a responding wireless station. An acknowledgement messages may be transmitted to the responding wireless station in response to receipt of the FTM message.

A system and method for generating dynamic playlists utilizing device co-presence proximity. In accordance with an embodiment, the method can include identifying music preferences by analyzing the listening history on a device of a user; and recognizing what devices are co-present within a set proximity for the purposes of matching such devices. In accordance with an embodiment, the system can be determine what music each individual in a group has been listening to historically, and determine when those individuals are within a certain proximity to one another, including for example analyzing the media content played on a smartphone and recognising when two smartphones are in a same location.

Embodiments of the present disclosure disclose a mobility management method, user equipment, and a base station. The mobility management method may include: receiving, by user equipment UE in a connected mode, a source identifier of the UE from a first base station, where the source identifier is used to uniquely identify the UE in the first base station; entering, by the UE, a low-overhead state in the case that a low-overhead activation condition is satisfied, where in the low-overhead state, the UE stores a connection context of the UE in the connected mode, and camps on a cell according to a cell reselection criterion during movement; and reporting, by the UE when a first preset condition is satisfied, the source identifier to a second base station to which a second cell belongs, where the second cell is a serving cell on which the UE currently camps.

Aspects of the present disclosure relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates an association between a sounding reference signal (SRS) resource set and a downlink reference signal resource to be used to determine a transmission property of one or more SRSs in the SRS resource set, wherein the downlink reference signal resource is associated with a first set of ports to be used for performing measurement of the downlink reference signal resource. The UE may determine the transmission property of the one or more SRSs in the SRS resource set using fewer ports than a number of ports included in the first set of ports, based at least in part on a determination that the UE is operating in a power saving mode. The UE may transmit the one or more SRSs using the transmission property. Other aspects are provided.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a message including an indication that the UE is in a power-saving mode. The UE may receive a configuration, for a connected state of the UE, that is based at least in part on the indication. The UE may operate in the connected state according to the configuration. Numerous other aspects are provided.

Methods and systems are for managing congestion in a network of devices are disclosed. A method may comprise identifying one or more battery-operated devices. A signal-to-noise ratio (SNR) and a signal-to-interference ratio (SIR) for each battery-operated device may be determined. Based on the SNR and SIR of each battery-operated device, a battery loss using clear channel assessment (CCA) and a battery savings using CCA may be determined. A total battery savings may be compared to a total battery loss to determine that the total battery savings is greater than the total battery loss. Based on the determination that the total battery savings is greater than the total battery loss, a noise may be generated to block transmission from the one or more battery-operated devices.
