Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, related to techniques for multiple transmission and reception point (TRP) transmission of channel state information reference signal (CSI-RS) resources. In one aspect, a user equipment (UE) can receive a CSI-RS resource including a first CSI-RS port on a first beam from a first cell of a network entity, the CSI-RS resource including a second CSI-RS port of the second cell on a second beam from a second cell of the network entity. In another aspect, a network entity can transmit, on a first beam from a first cell to a UE, a CSI-RS resource including a first CSI-RS port of the first cell, and transmit, on a second beam from a second cell to the UE, the CSI-RS resource including a second CSI-RS port of the second cell.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently determining when to transmit a beam report indicating a new beam for communicating with a base station after a current beam used for communications with the base station fails. In one example, after detecting beam failure, a user equipment (UE) may compare a quality of each candidate beam available for communicating with a base station to a beam identification threshold, and the UE may perform beam reporting based on the comparisons (e.g., refrain from transmitting a beam report if the quality of each of the candidate beams is lower than the beam identification threshold). In another example, after detecting beam failure, a UE may compare a quality of each candidate beam available for communicating with a base station to a beam detection threshold, and the UE may perform beam reporting based on the comparisons.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indicator of a feedback window that is offset relative to a beginning transmission time interval (TTI) of a set of consecutive TTIs. The consecutive TTIs may include a set of aggregated slots or may correspond to a multi-TTI grant. The feedback window may include multiple control channel occasions interspersed within a duration of the set of consecutive TTIs. The UE may receive a transport block within a first TTI of the set of consecutive TTIs and transmit, within a control channel, feedback to indicate whether the transport block was successfully received.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may use beamforming to transmit control and data transmissions to a set of user equipments (UEs). A base station may transmit downlink control information (DCI) to UEs that may indicate a set of resource allocations in which the base station may schedule a data transmission, and a respective transmission configuration indicator (TCI) state. The TCI state may indicate which transmission beam the base station may use to transmit a data transmission in a particular resource allocation. The UE may receive and decode the DCI and identify resource allocation information and an index that may indicate one or more TCI states being used for transmitting a broadcast or unicast transmission to the UE within a resource allocation. The UE may select one or more of the resource allocations to monitor for, and subsequently receive, the data transmission.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for updating beam information across a plurality of component carriers (CCs) via downlink control information (DCI). An exemplary method, performed by a user equipment (UE), generally includes receiving, from a network entity, a downlink control information (DCI) for an update for at least of a beam or path loss (PL) reference signal (RS) activation and applying the update across at least one of a group of component carriers (CCs) or bandwidth parts (BWPs) within the group of CCs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may determine whether to transmit a sidelink timing synchronization signal to a second UE based at least in part on a sidelink zone in which the first UE is located and a sidelink zone in which the second UE is located. The first UE may selectively transmit the sidelink timing synchronization signal to the second UE based at least in part on determining whether to transmit the sidelink timing synchronization signal to the second UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that allow for a first user equipment (UE) to forward a transmission from a second UE to a base station. The forwarding techniques may include the first UE performing a decoding procedure on a message received from the second UE via a sidelink communications link. Based on the results of the decoding procedure, the first UE may select an amplify and forward (AF), decode and forward (DF), or a combination thereof to forward the message from the second UE to the base station. The base station may receive the forward messages and, in some cases, a message directly from the second UE, and may determine decoding weights to use to jointly decode the two messages received at the base station.

Abstract: Systems, apparatuses, and methods for enhancement for amplify-and-forward relay. Instead of merely passing received signal from a source, relay may equalize the received signal based on reference signal contained in the received signal, before amplifying and transmitting the signal to a destination. Compared to amplify-and-forward, equalize-and-forward may compensate the received source signal for various imperfections such as channel distortions and phase errors, using demodulation reference signal and phase tracking reference signal. The relay may apply Fast Fourier Transform (FFT) to equalize the signal in tone domain.
