Abstract: Certain aspects of the present disclosure provide a method for wireless communications between a first UE and a second UE. The method includes, at the first UE, receiving, from the second UE, a paging indication message on a sidelink channel, the paging indication message associating the first UE with one or more resources of a common resource pool that includes a plurality of resources for communication on the sidelink channel. The method further includes, based on the received paging indication message, monitoring the one or more resources for a message from the second UE.

Abstract: Using a modulation and coding scheme for a control channel that is more conservative than needed to fulfill the control function may waste resources. To address this issue, a variable size control channel is provided. An apparatus in such a system may be configured to determine an aggregation level of a plurality of aggregation levels associated with a control channel. Each aggregation level of the plurality of aggregation levels is associated with a number of time-frequency resources dedicated for the control channel and a particular modulation and coding scheme used for modulating and coding control information in the control channel. The apparatus is configured to receive control information in the time-frequency resources associated with the aggregation level and decode the control information received in the time-frequency resources associated with the determined aggregation level. The decoding is based on the particular modulation and coding scheme associated with the determined aggregation level.

Abstract: Embodiments include systems and methods for sidelink communications. In embodiments, a processor of a wireless device may determine signal strength information and priority information associated with a sidelink communication resource. The processor may determine coordination information based on the determined signal strength information and priority information. The processor may generate a message to include the determined coordination information. The processor may transmit the generated message including the determined coordination information to a second wireless device. In some embodiments, the generated message may be a control message, such as a medium access control control-element (MAC-CE) or a sidelink control information message.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a host wireless device may transmit a discovery message to a client wireless device. The client wireless device may transmit a random access channel (RACH) preamble on a first time domain resource to the host wireless device in response to the discovery message. The client wireless device may later transmit a second RACH message to the host device on a second time domain resource after the first time domain resource. The second time domain resource may be defined by a mapping from the first time domain resource. The host device may transmit a third RACH message establishing a communication session between the host wireless device and the client wireless device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect an out-of-coverage scenario based at least in part on determining that a synchronization source associated with a wireless network is unavailable or has a signal strength that fails to satisfy a threshold. The UE may transmit, on a sidelink channel, a sidelink synchronization signal in a transmission period that includes a plurality of synchronization signal occasions based at least in part on the out-of-coverage scenario. In some aspects, the UE may transmit the sidelink synchronization signal according to a reduced duty cycle that causes the sidelink synchronization signal to be transmitted during fewer than all of the plurality of synchronization signal occasions. Numerous other aspects are provided.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a pedestrian user equipment (PUE). The apparatus may be configured to monitor a first set of resources to detect a paging indicator indicating a paging message is carried on a second set of resources allocated for vehicle-to-pedestrian (V2P) communication consecutive to the first set of resources; to decode information on the second set of resources to detect the paging message from a second UE when the paging indicator is detected, the paging message being associated with the V2P communication; and to refrain from decoding the information on the second set of resources when the paging indicator is undetected.

Abstract: Aspects relate to mechanisms for a base station to provide sidelink synchronization assistance to a plurality of user equipment (UEs). The base station may be configured to identify a detection time window that includes a sidelink synchronization resource configured for transmission of a sidelink synchronization signal on a sidelink carrier. The base station may further be configured to transmit an indication of the detection time window to the plurality UEs on a cellular carrier to enable the UEs to detect a sidelink synchronization signal on the sidelink carrier within the detection time window and synchronize communication on the sidelink carrier.

Abstract: Wireless communication devices are adapted to facilitate power conservation and sidelink communications. According to one example, a wireless communication device can transmit a reservation signal to reserve one or more sidelink resources for use by another device, and receive a sidelink transmission from the other device on at least a portion of the one or more reserved sidelink resources. According to another example, a wireless communication device can detect a reservation signal from another device, where the reservation signal is configured to reserve one or more sidelink resources, and transmit a sidelink transmission on at least a portion of the one or more of the sidelink resources reserved by the other device. Other aspects, embodiments, and features are also included.
