Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a wake up time period corresponding to a wake up cycle, transmit a message that includes an identifier of the UE within a first resource pool during a first portion of the wake up time period based on the wake up cycle, and monitor for a paging signal from a vehicle UE during a paging occasion of the wake up time period based on transmitting the message. A vehicle UE may identify a wake up configuration for a wake up time period, receive, within a first portion of the wake up time period, a message within a resource pool that includes the identifier of the UE. The vehicle UE may transmit a paging signal within a paging occasion of the wake up time period.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.

Abstract: Embodiments are provided herein for reducing neighbor cell monitoring by a mobile communication device that may include measuring a channel condition of the cell serving the idle network subscription, determining whether the measured channel condition of the cell serving the idle network subscription satisfies a threshold value, and in response to determining that the measured channel condition of the cell serving the idle network subscription satisfies the threshold value, reducing a frequency at which neighbor cells associated with the idle network subscription are monitored and monitoring the neighbor cells associated with the idle network subscription according to the reduced frequency.

Abstract: Aspects of the disclosure relate to wireless communication in connection with one or more devices, such as a mobile station (MS). A first burst of a multi-burst page is received from a paging channel. A correlation between at least a portion of the first burst and each of a plurality of predetermined bit patterns corresponding to a non-NULL page destined for the MS is determined. If the correlation is greater than a threshold, a second burst of the page is read and early decoding of the page is performed. Other aspects, embodiments, and features are also claimed and described.

Abstract: Access terminals are adapted to regulate power in wireless receiver circuits. In one example, access terminals include a communications interface with at least one wireless receiver circuit. A processing circuit coupled with the communications interface can receive a transmission during a Frequency Correction Channel (FCCH) frame. Following the received transmission, at least a portion of the receiver circuit may be powered down. A determination may also be made whether the received transmission was reliable. The receiver circuit can subsequently be powered up, and another transmission can be received on a subsequent channel. When the received transmission was sufficiently reliable, the other transmission may be a transmission during a Synchronization Channel (SCH) frame. When the received transmission is not sufficiently reliable, the other transmission may be another transmission received during a subsequent Frequency Correction Channel (FCCH) frame. Other aspects, embodiments, and features are also claimed and described.

Abstract: Access terminals are adapted to blacklist one or more neighboring cells from acquisition attempts. For instance, an access terminal may receive a transmission including a list of neighboring cells to be monitored while connected to a particular serving cell. The access terminal may determine that a predefined number of consecutive acquisition attempts with a particular neighboring cell have failed. In response to failure of the predefined number of consecutive acquisition attempts, the access terminal can blacklist the neighboring cell from subsequent acquisition attempts for a predefined blacklisting period. Following the duration of the blacklisting period, the access terminal may conduct a subsequent acquisition attempt with the neighboring cell. Other aspects, embodiments, and features are also claimed and described.
