Abstract: Certain aspects of the present disclosure provide techniques for direct transport block (TB) forwarding in relaying operations. A method that may be performed by a relay node includes receiving, from a source node, an indication to directly forward a TB to a destination node, wherein directly forwarding includes transmitting the TB to the destination node through only a Physical (PHY) layer and a hybrid automatic repeat request (HARM) portion of a Media Access Control (MAC) layer in a protocol stack of the relay node and directly forwarding the TB to the destination node based, at least in part, on the indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine an estimated total amount of resources for one or more retransmissions of communications among the base station, a controller, and a device, the one or more retransmissions associated with one or more transmissions between at least two of the base station, the controller, or the device; and transmit, to at least one of the controller or the device, an indication of an allocation of resources based at least in part on the estimated total amount of resources for the one or more retransmissions. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive signaling indicating a phase tracking reference signal (PTRS) configuration for sidelink communications. The indicated PTRS configuration may correspond to a sidelink resource pool associated with a plurality of UEs. The UE may transmit control signaling indicating to change the indicated PTRS configuration to a preferred PTRS configuration for the sidelink communications based on a condition. The UE may receive the sidelink communications based on the preferred PTRS configuration.

Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may receive, from a second UE, an indication of a first uplink timing advance for communications from the second UE to a base station. The UE may estimate, based at least in part on the first uplink timing advance received from the second UE, a second uplink timing advance for transmission of a random access message from the first UE to the base station. The UE may transmit, to the base station, the random access message using the second uplink timing advance.

Abstract: Apparatus, methods, and computer-readable media for facilitating phase jump estimation for SL DMRS bundling are disclosed herein. An example method includes receiving, from another device, first information at a first symbol of a first slot, the first slot including at least the first symbol and a first reference signal. The example method also includes receiving second information at a second symbol of a second slot, the second slot including at least the second symbol and a second reference signal, the first information and the second information being repetitions. The example method also includes generating a first reference signal copy based at least on the second reference signal and a phase jump between the first slot and the second slot. Additionally, the example method includes performing channel estimation across the first slot and the second slot based on an aggregation of the first reference signal and the first reference signal copy.
