Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform single frequency network (SFN) manner relaying in sidelink to support exchanging packets between UEs, for example, without maintaining beamforming alignment between the UEs. A first UE (e.g., a source UE or destination UE) may establish a pre-agreement with a second UE for the second UE to operate as an SFN-manner relay over sidelink for the first UE. The pre-agreement may be reached via a publish-and-subscription procedure, in which the second UE publishes an SFN-type relaying service and the first UE subscribes to the SFN-type relaying service. The second UE may receive sidelink signaling associated with the first UE (e.g., transmitted by or to the first UE) and may relay the sidelink signaling in a resource configured for SFN-type transmission based on the first UE being subscribed to the SFN-type relaying service.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a first user equipment (UE) may receive a control message from a second UE indicating resources that are reserved for communications between the first UE and the second UE. The first UE may transmit a first control message and a second control message for reassurance of the reserved resources. The first UE may transmit a first control message for reservation reassurance, and the first control message may indicate a resource configuration for a second control message for reservation reassurance. The first UE may transmit an indication of the reserved resources, resource reservation reassurance information, or both via the second control message. A third UE may receive the first and second control messages and may refrain from communicating on the reserved resources based on the indication.

Abstract: Systems, methods, and devices for wireless communication that support resource selection and indication for sidelink demodulation reference signal (DMRS) bundling. A transmitting UE determines sidelink resources for bundling a sidelink DMRS transmission to be transmitted to a receiving UE. In sidelink mode 1, the sidelink resources may be determined based on indications from a base station, which may include whether the transmitting UE is to maintain phase continuity over the sidelink resources during the bundling, or whether the transmitting UE is to include a phase jump reference signal with the bundled DMRS transmission to the receiving UE. In sidelink mode 2, the transmitting UE may select the sidelink resources based on the phase continuity capabilities of the transmitting UE and/or of the receiving UE, and/or based on a sensing of the sidelink channel. In some cases, the receiving UE may provide a resource recommendation to the transmitting UE.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting user equipment (UE) may determine a set of resources for sidelink communication with one or more neighboring UEs. The transmitting UE may transmit multiple sidelink control messages to the neighboring UEs indicating the set of resources are reserved for a sidelink data message. The neighboring UEs may receive at least one of the sidelink control messages. A neighboring UE may determine a portion of the resources are reserved for a sidelink data message with the transmitting UE and may transmit or receive the sidelink data message using the portion of the resources. Additionally or alternatively, a neighboring UE may determine the resources are reserved for a sidelink data message between the transmitting UE and another neighboring UE and may select alternative resources for sidelink data messages to may avoid using the reserved resources.

Abstract: Methods, systems, and devices for wireless communications are described that support evolved semi-persistent scheduling (SPS) for wireless communications. A base station may configure SPS in which multiple time intervals are scheduled, each time interval including multiple slots that may be scheduled by different uplink or downlink resource allocations. The SPS configuration may include an ON-OFF duty cycle where an ON portion of the duty cycle spans a portion of a time interval and includes uplink and downlink resources, and an OFF portion of the duty cycle spans a remaining portion of the time interval and does not include any allocated SPS resources. Such SPS configurations may be used, for example, for transmitting sensor data and command information between controllers and sensors/actuators in a factory automation network.

Abstract: Methods, systems, and devices for wireless communications are described that support sidelink cancellation for out of coverage user equipment. Described techniques provide for signaling of cancellation indications to a user equipment (UE) or a group of UEs to refrain from performing sidelink communications on a set of resources. A base station may transmit a cancellation indication to one or more sidelink UEs via an access link that indicates that an allocation of one or more resources for sidelink communications has been canceled. A first UE may receive the cancellation indication from the base station via the access link and transmit a sidelink communication to one or more other UEs that indicates the canceled resource allocation. Based on the sidelink communication of the cancellation indication from the first UE, the one or more other UEs may refrain from transmitting using the canceled resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to one or more other UEs in a group of wireless network devices that includes the first UE and the one or more other UEs, an indication that the UE is a current sidelink scheduler for the UEs in the group of wireless network devices. The UE may receive, from at least one other UE in the group of wireless network devices, a scheduling request for a sidelink communication to be transmitted by the at least one other UE. The UE may transmit, to the at least one other UE, a grant of resources for the sidelink communication to be transmitted by the at least one other UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless devices may communicate over a primary and fallback beam. To support communications over a primary and fallback beam, a preconfiguration procedure may be performed to communicate to a transmitting and receiving device the identity of the primary and fallback beam. A central scheduling node may assist in identifying the primary and fallback beam for the transmitting and receiving device. During communications, the transmitting and receiving device may switch to the fallback beam when an initial communication fails and may perform a retransmission that includes data from the initial communication over the fallback beam.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication over a sidelink between a transmitting user equipment (UE) and a receiving UE. The receiving UE may receive a configuration of multiple resource pools for sidelink communications. The transmitting UE may transmit at least two repetitions of a sidelink control information (SCI) on at least two of the multiple resource pools. Each repetition of the SCI includes a reservation for a physical sidelink shared channel (PSSCH) on a respective resource pool. The receiving UE may perform soft combining on the at least two repetitions of the SCI to determine resources for the PSSCH. The receiving UE may decoding the PSSCH based on the SCI, for example, by combining multiple repetitions of the PSSCH on the reservations indicated by the SCI.

Abstract: In an embodiment, a transmission reception point (TRP) apparatus of a Coordinated Multipoint (CoMP) network, determines a periodicity of periodic traffic between the TRP apparatus and a user equipment (UE), and schedules a Channel State Information (CSI) process in advance of a traffic window for a next instance of the periodic traffic in accordance with the determined periodicity. In another embodiment, the UE of the CoMP network performs the CSI process in advance of the traffic window for the next instance of periodic traffic between the UE and the TRP apparatus, the CSI process being scheduled in accordance with the determined periodicity of the periodic traffic.
