Abstract: Methods, systems, and devices for wireless communications are described for closed-loop precoding for multiple-input multiple-output for transmitter circle arrays, for example uniform circular array panels. In some aspects, a base station including a transmitter circle array may steer a beam to a user equipment (UE) using codebooks, quantization rules, and feedback from the user equipment. In some aspects, the same transmitter circle array may be used for both backhaul communications with a device at a fixed location, for example using beams formed via discrete Fourier transform (DFT) vectors, and access communications with a UE via non-DFT beams coded using closed-loop precoding.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver of a holographic multiple input multiple output (MIMO) communication may receive, using at least one receive antenna element, a plurality of reference signals associated with at least one transmit antenna element of a transmitter of the holographic MIMO communication. The receiver may communicate using two-dimensional beams or three-dimensional beams based at least in part on a determination of a beam format associated with the plurality of reference signals. Numerous other aspects are described.

Abstract: A sensing node may receive a set of sensing signals. The sensing node may calculate a first joint spectrum based on a first windowing function and the set of sensing signals. The sensing node may calculate a second joint spectrum based on a second windowing function and the set of sensing signals, wherein the first windowing function is different than the second windowing function. The sensing node may transmit a first joint spectrum report based on the first joint spectrum and a second joint spectrum report based on the second joint spectrum to a sensing entity. The sensing node may estimate a parameter of a target object based on an optimal spectrum ID received from the sensing entity, where the optimal spectrum ID may be associated with at least one of the first joint spectrum or the second joint spectrum.

Abstract: Disclosed are systems and techniques for wireless communications. For instance, a process can include determining a number of multiple-input, multiple-output (MIMO) paths to be used for transmission of a message, identifying, from a set of possible MIMO paths, a plurality of MIMO paths for allocation of transmit power based on the number of MIMO paths to be used and a physical layer security configuration, and allocating the transmit power across the plurality of MIMO paths to transmit a message.

Abstract: Aspects presented herein may enable a wireless device (e.g., a joint FMCW radar and communication system) to transmit and/or receive an FMCW signal and an OFDM signal using the same time and frequency resources. In one aspect, a first wireless device receives an indication of a scheduled transmission for an FMCW waveform via a set of time-frequency resources. The first wireless device transmits or receives the FMCW waveform via the set of time-frequency resources based on the indication, where the FMCW waveform is separated from an OFDM waveform by a buffer zone including a first gap in frequency, where the first gap in frequency is based on an interference level between the FMCW waveform and the OFDM waveform.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless communication device may obtain information regarding communication between the set of communication devices and a non-terrestrial network (NTN) and communicate with the NTN. The wireless communication device may communicate with the NTN directly based on the wireless communication device being identified as one of one or more selected wireless communication devices for direct communication with the NTN. The wireless communication device may communicate with the NTN indirectly via a peer-to-peer communication network and the one or more selected wireless communication devices based on the wireless communication device being not identified as any of the one or more selected wireless communication devices for direct communication with the NTN.

Abstract: Methods, systems, and devices for wireless communications are described. A first device (e.g., a base station) may transmit reference signals to a second device (e.g., a user equipment (UE)) via transmitter antenna circles. The second device may receive and measure the reference signals via corresponding receiver antenna circles. Both the transmitter antenna circles and the in receiver antenna circles may include a center antenna circle and one or more peripheral antenna circles. The second device may transmit channel gain measurements to the first device based on measuring the reference signals. The first device may determine orbital angular momentum (OAM) modes, a power loading scheme, or both for the transmitter antenna circles based on the channel gain measurements. The first device may transmit OAM transmissions to the second device based on the determined OAM modes, the power loading scheme, or both. The OAM transmissions may have different OAM states, polarizations, or both.

Abstract: Aspects presented herein may enhance the navigation function of navigation/map applications or systems when GNSS signals are weak or sporadic. In one aspect, a UE monitors a position of the UE based on GNSS communication, where the position of the UE is monitored using at least one first map layer of a plurality of map layers associated with a map. The UE detects that the position of the UE corresponds to a predefined location when the GNSS communication is below a communication threshold. The UE switches to monitoring the position of the UE using at least one second map layer of the plurality of map layers upon detecting that the position of the UE corresponds to the predefined location, where the at least one second map layer is associated with the predefined location.

Abstract: Aspects relate to an array antenna and communication using the array antenna. In some examples, the array antenna includes a first array of antenna elements arranged according to a first circle and a second array of antenna elements arranged according to a second circle, where the first circle and the second circle are concentric circles. In some examples, the first array of antenna elements is arranged with an angular offset with respect to the second array of antenna elements. For example, a first radius associated with a first antenna element of the first array of antenna elements may be offset at an angle with respect to a second radius of a second antenna element of the second array of antenna elements.
