Abstract: Methods, systems, and devices for wireless communications are described. A repeater may transmit a beacon signal that indicates a presence of the repeater, where the repeater is configured to repeat signals to one or more user equipments (UEs) within a wireless communications system. The repeater may receive a signal from at least one base station within a time-frequency resource that is shared by a plurality of neighboring base stations in response to transmitting the beacon signal. The repeater may transmit an amplified version of the received signal to the one or more UEs.

Abstract: Methods, systems, and devices for wireless communications are described in which RF-domain wireless routers may repeat, extend, or redirect beamformed wireless signals received from one or more transmitters to one or more receivers. The router may receive transmissions at a mmW frequency using a first array of antenna elements, and provide the transmissions to a beamforming network, such as a Butler matrix, that outputs one or more a signals to a switching network. The switching network may perform switching to provide the one or more signals to desired inputs of an output beamforming network that outputs beamformed transmission beams via a second array of antenna elements.

Abstract: Various aspects of the disclosure relate to reporting a power limit along with an indication of at least one constraint upon which the power limit is based. In some aspects, the constraint is a radio frequency (RF) exposure constraint. For example, a power headroom limit calculated by a first apparatus may be constrained by a specific absorption rate (SAR) limit or a maximum permissible exposure (MPE) limit. The first apparatus may thus report to a second apparatus the current power headroom limit of the first apparatus along with an indication of whether the power headroom limit is constrained by an SAR limit or an MPE limit (e.g., as opposed to being constrained by a maximum transmit power limit). The second apparatus may then schedule the first apparatus taking into account the power headroom limit and the corresponding constraint (e.g., maximum power or SAR/MPE).

Abstract: Apparatus and methods for updating symbol information in a communication device with hardware such as a microcontroller are disclosed. The disclosed apparatus and methods employ waiting for the beginning of a symbol in a sample stream at a predetermined time. One or more programmed instructions are read at the beginning of the symbol, and then symbol information is updated based on the one or more programmable instructions and setting a time for a beginning of a next symbol. The programmed instructions consist of instruction code words that are executed by a dedicated microcontroller or similar hardware, which affords flexibility for updating symbol information, particularly for multimode communication devices operable across multiple communication technologies.

Abstract: Disclosed is a method for wireless communication for determining the position of a wireless node. The method comprises receiving a set of reference signals from a set of at least four positioning devices, wherein the positioning devices are not arranged in a single plane. A signal propagation delay of each one of the set of reference signals is determined and a position of each one of the set of positioning devices is obtained. A convex localization problem is solved for the wireless node based at least in part on the determined signal propagation delay of each one of the set of reference signals and the position of each one of the set of positioning devices. The position of the wireless node is determined based at least in part on solving of the convex localization problem.

Abstract: Methods, systems, and devices for wireless communications supporting techniques for enhanced line-of-sight (LOS) communications with analog multi-path beamforming are described. A first wireless device may receive, from a second wireless device, an indication of a capability of the second wireless device to concurrently transmit first signaling in a first analog beamforming direction using a first transmission configuration indicator (TCI) state corresponding to a LOS mode, and second signaling in a second analog beamforming direction using a second TCI state corresponding to an indirect LOS mode. The first wireless device may then receive, from the second wireless device, a first downlink message in the first analog beamforming direction using the first TCI state concurrently with a second downlink message in the second analog beamforming direction using the second TCI state.

Abstract: The present disclosure relates to dynamic antenna array reconfiguration and signaling in millimeter wave bands. A user equipment (UE) may detect an antenna array change condition. The UE may transmit a request for beam training for an antenna array configuration in response to the detecting. The request for beam training may include a requested antenna array configuration for the UE and an indication of beam weights to use with the requested antenna array configuration. A base station may determine whether to grant or deny the requested antenna array configuration for the UE. The UE may receive, from the base station, an indication of an antenna array configuration for the UE. The base station may transmit the number of reference signals as a set of contiguous channel state information reference signals (CSI-RS). The UE may train the reconfigured active antenna array configuration based on the reference signals.

Abstract: Methods, systems, and devices for wireless communications are described. A repeater may apply a frequency translation and a phase rotation adjustment to a transmitted signal to avoid radio frequency interference. For instance, wireless repeater may receive a signal from a first device on a first carrier frequency. The wireless repeater may identify one or more interfering signals affecting the reception or transmission of the signal. The wireless repeater may then perform a frequency translation from the first carrier frequency to the second carrier frequency, and may also apply a phase rotation adjustment corresponding to the frequency translation. The wireless repeater may retransmit the signal including the phase rotation adjustment over the second carrier frequency to a second device in the wireless network.
