Abstract: A relay supporting multiple relay modes is provided. The relay transmits capability information to a base station, the capability information indicating support for a first relay mode and a second relay mode. The relay determines a mode of operation, either on its own or based on an indication of a mode of operation from the base station, wherein the mode of operation comprises the first relay mode or the second relay mode. The relay communicates with at least one of the base station or another wireless device based at least in part on the determined mode of operation.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication relay may receive, via a first wireless link with a base station, a scheduling request that identifies scheduling information for scheduling transmission or reception of data via a second wireless link with a network node. The wireless communication relay may transmit, via the second wireless link, a scheduling command in accordance with the scheduling information. The wireless communication relay may transmit or receive, via the second wireless link, the data in accordance with the scheduling information. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums to enhance the functionality of directional repeaters (wireless nodes that relay directional wireless signals). For example, by adding even limited capability to buffer digital samples, repeater functionality may be enhanced to provide better coverage and make more efficient use of time, frequency, and spatial resources.

Abstract: Certain aspects of the present disclosure generally relate to radio frequency (RF) front-end circuitry. For example, certain aspects provide an apparatus having a first converter circuit configured to upconvert a first baseband (BB) signal to a first RF signal based on a mode of operation, and a second converter circuit configured to upconvert a second BB signal to a second RF signal based on the mode of operation. The apparatus also includes a first RF weight adjustment circuit configured to selectively apply an amplitude weight or a phase weight to at least one of the first RF signal or the second RF signal based on the mode of operation, and a controller configured to control a power state of the second converter circuit in dependence on the mode of operation.

Abstract: Various aspects of the disclosure relate to communicating uplink control information. As one example, a user equipment may send uplink control information to a base station. In some aspects, the number of symbols used to communicate the uplink control information may be based on a link gain associated with the UE and/or based on a payload size of the uplink control information. As another example, the user equipment may send channel information for a number of beams to the base station. In some aspects, the number of beams may be based on the type of channel that is used to send the uplink control information.

Abstract: In order to maintain conformance with exposure limits, in band measurements may be performed. A method, a computer-readable medium, and an apparatus may be provided for wireless communication at a user equipment. The apparatus receives an indication of a cell specific resource, e.g., a cell specific resource available for MPE measurement. The apparatus then performs a measurement based on the cell specific resource and determines whether to adjust a transmission characteristic of the user equipment based on whether the measurement meets a threshold. In another aspect a base station apparatus may configure a cell specific resource in which a user equipment may perform an MPE measurement and control use of the cell specific resource for the MPE measurement.
