Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may configure one or more first sets of resources of a radio frequency spectrum band associated with a first pathloss mode, and may configure one or more second sets of resources associated with a second pathloss mode. Each set of resources may be configured with some transmission timing parameters and frame structure, such that a transmission time interval (TTI) associated with the first pathloss mode may be different from the TTI associated with the second pathloss mode. The wireless device may communicate with a second wireless device using the one or more first sets of resources based on identifying a pathloss value is below an identified pathloss threshold. Additionally, the wireless device may communicate with a third device using the one or more second sets of resources based on identifying a pathloss value satisfies the identified pathloss threshold.

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: Methods, systems, and devices for wireless communications are described that provide for the management of different operation modes in wireless systems. For example, wireless device(s) may operate in a high pathloss operation mode or a normal pathloss operation mode based on the pathloss experienced between the transmitting and receiving devices. In some cases, a first wireless device may transmit a message to a second wireless device to configure a bandwidth part (BWP) for high pathloss mode communications. The message may be transmitted via control signaling and after receipt of the message, the second wireless device may enter a high pathloss mode for communications with the first wireless device (e.g., after a given time duration). Some parameters may be configurable (e.g., transmission duration, coding scheme) between high pathloss mode and normal pathloss mode, while other parameters may remain the same (e.g., processing time, switching time).

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.

Abstract: Methods, systems, and devices for wireless communications are described. To communicate messages using one or more grating lobes of a directional beam, a first device (e.g., a user equipment (UE), a base station) may transmit, to a second device, control signaling that indicates the transmission of a message on a grating lobe. The first device may determine a set of beamforming parameters for simultaneously transmitting the message to the second device and a third device. The first device may simultaneously transmit the message to third device on a main lobe and to the second device on the grating lobe. Additionally, or alternatively, the first device may simultaneously receive a message on a main lobe and a grating lobe of a directional beam. The first device may also communicate control signaling that indicates whether to simultaneously communicate the message on the main lobe and the grating lobe.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. A transmitter node and a relay node transmit, to a base station, feedback related to complex channel estimates associated with beam pairs providing viable paths for a first link between the transmitter node and the base station, a second link between the relay node and the base station, and a third link between the transmitter node and the relay node. The transmitter node transmits a signal to the base station using a transmit beam associated with a first beam pair and to the relay node using a transmit beam associated with a second beam pair. The base station receives the signal from the transmitter node and an estimate of the signal from the relay node via a receive beam configured based at least in part on the complex channel estimates included in the feedback. Numerous other aspects are provided.

Abstract: An apparatus for wireless communication based on sidelink accumulates a value, e.g., a token value, based on an accumulation rate of a transmit beam. When the apparatus has a packet for transmission over sidelink, the apparatus determines whether to transmit the packet over the sidelink based on a current accumulation of the value. The accumulation may be based on any of a CBR, a CR, and/or a feedback rate. A base station may measure interference on an access link of the base station and transmit a side link parameter that controls accumulation of a value at a transmitting device for the transmission of sidelink communication based on the measured interference.
