Abstract: A node including an RU and a control entity is disclosed. The node may receive, from a base station at a control entity of the node, an indication of at least one obstruction for communication via at least one reflective surface. The indication may indicate to the control entity to utilize an RU of the node and the at least one reflective surface for communication. The node may configure, upon receiving the indication of the at least one obstruction, the RU and the at least one reflective surface for communication with the base station. The node may forward communication received from, or forward communication to, the base station via the RU and the at least one reflective surface based on the at least one obstruction for communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine, for full-duplex mode communication on a first link and a second link, a timing adjustment to at least one of a first timing or a second timing, wherein the timing adjustment is to cause a delay between clutter reflection from a first signal and an occurrence of a second signal to occur during a cyclic prefix of the second signal; cause the timing adjustment to be applied to the at least one of the first timing or the second timing; and communicate in the full-duplex mode with a first node and a second node in accordance with the timing adjustment, wherein communicating includes transmitting the first signal to the first node and receiving the second signal from the second node. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of bandwidth part (BWP) combinations for an inter-band carrier aggregation configuration in a frequency range above 24 GHz. The UE may transmit an indication of the set of BWP combinations to initiate a reconfiguration of a BWP combination for the UE. Numerous other aspects are provided.

Abstract: A wireless device of the present disclosure may be able to reduce the time needed to determine a subarray and/or beamforming direction used for mmW communication. An apparatus may maintain first information associated with a correlation between each of a plurality of wireless device orientations and a plurality of nodes, at least one subarray, and a corresponding beamforming direction. The apparatus may communicate with a first node using a first beamforming direction selected from the first information. In certain aspects, the first beamforming direction may be correlated with a first orientation of a first subarray at the wireless device and the first node. The apparatus may perform a handoff procedure from the first node to a second node when a position of the first subarray changes from the first orientation to a second orientation.

Abstract: In wireless communication systems that support 5G or NR protocols, subframes used for communication may have different numerology options. Numerology options may refer to the characteristics of the subframe such as a tone spacing within each symbol of the subframe, a symbol duration for each symbol of the subframe, a number of symbols in the subframe, etc. A subframe may include a control channel (e.g., the PDCCH) and a data channel (e.g., the PDSCH). In an aspect, the control channel and the data channel within the subframe may have different numerologies. As such, a need exists to signal the numerology of the subframe to users and to determine whether and how to multiplex the control channel and the data channel into the subframe.

Abstract: The base station that is configured to transmit in a beamformed manner may set different transmission rates for different directions of the beams. During an initial access stage, the base station may set different transmission rates for different transmission directions, and may transmit initial access signals based on the transmission rates in the different transmission directions The apparatus may be a base station. The base station determines transmission rates for a plurality of transmission directions, where each transmission rate is determined for a respective transmission direction of the plurality of transmission directions. The base station transmits at least one initial access signal in each of one or more of the plurality of transmission directions based on a corresponding transmission rate of the transmission rates.

Abstract: Methods, systems, and devices for wireless communications are described. A codebook adaptation may be performed for a flexible user equipment (UEs) to determine a codebook for a physical configuration of the UE. For example, if the UE determines that the physical configuration does not correspond to a pre-loaded codebook in its memory, the UE may provide information about the physical configuration to a base station to determine a corresponding codebook. Additionally, the UE may request that the base station provide channel information to assist with the codebook determination. In some cases, this request may indicate for the base station to allocate a specific number of channel state information reference signal symbols that the UE can use for the codebook determination. Additionally or alternatively, the UE may generate the codebook internally and then signal to the base station a request for a beam refinement procedure with the generated codebook.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a reflecting device may generate a multi-peak reflection beam that spatially multiplexes a first reflected signal of a first signal and a second reflected signal of a second signal. The reflecting device may receive the first signal and the second signal. The reflecting device may reflect the first signal and the second signal to output a spatially multiplexed reflected signal using the multi-peak reflection beam. Numerous other aspects are described.
