Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a broadcast transmitter, a broadcast signal including one or more multi-resolution messages. The UE may decode at least one of the one or more multi-resolution messages based on receiving the broadcast signal from the broadcast transmitter, and may determine that a data rate associated with the broadcast signal is less than a threshold based on the decoding. The UE may transmit a signal querying the broadcast reception capability of a base station based on determining the data rate. In response to the query signal, the UE may receive a signal indicating a broadcast reception capability of the base station, and may communicate, with the base station, based on the broadcast reception capability of the base station.

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: Methods, systems, and devices for wireless communications are described. Different periodicities may be dynamically selected when monitoring and transmitting signaling used for link management, where respective periodicities may be based on the quality of the link between devices. For instance, a first wireless device may use a first monitoring periodicity to monitor for signals transmitted from another wireless device. Upon determining that a link condition has changed (e.g., decreased or reached a threshold), the first wireless device may decrease its monitoring periodicity (and increase monitoring frequency) to detect signals transmitted by the other wireless device more frequently. In such cases, the other wireless device may likewise transmit its measurement signals more often (e.g., in accordance with a second periodicity) based on the link quality. The adjusted monitoring and transmission periodicities may provide additional occasions for the wireless device to detect signals from another device.

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: The described techniques provide for the identification and utilization of different power consumption categories by a user equipment (UE) in wireless communications system. A power consumption category may correspond to a power consumption level (e.g., a powered circuitry configuration) of the UE. For example, a power consumption category may configure an analog-to-digital conversion (ADC) resolution, a digital-to-analog conversion (DAC) resolution, a number of antennas, etc., that a UE may employ for communications. In some examples, a UE may report capability information to a base station, and the base station may use the information to explicitly or implicitly (e.g., via conveying thresholds or conditions to the UE for power consumption category switching or power consumption category selection) configure the UE with various power consumption categories. As such, the power consumption categories may be used by the base station and UE, in some scenarios, for reducing power consumption.

Abstract: Wireless communication techniques that include beam training performed to aid mobile devices in identifying beams for use in communications (e.g., uplink communications) are discussed. A mobile device may transmit to a base station an indication of a level of beamforming reciprocity of the mobile device. A base station/gNB may transmit an indication of one or more transmission beams to be used by the mobile device for uplink wireless communication based on the level of beamforming reciprocity. The one or more transmission beams to be used by the mobile device for uplink communication may include a reciprocal transmission beam. A mobile device not capable of full beamforming reciprocity may determine a transmission beam through uplink beam training. A mobile device may transmit to a base station information using at least one of the one or more transmission beams. Other aspects and features are also claimed and discussed.

Abstract: Methods, systems, and devices for wireless communication are described in which a number of reference signal processes may be configured for a number of slots in a radio frame, and a corresponding reference signal process for each slot may be based at least in part on a location of the slot within the radio frame and a number of configured reference signal processes. An indication may be provided to a user equipment (UE) in each slot that indicates a presence or absence of a reference signal transmission in the slot.

Abstract: A user equipment (UE) receives a first synchronization signal (SS) block including a first codeword and a second SS block including a second codeword. Each codeword is based on a linear encoding of a physical broadcast channel (PBCH) payload. The PBCH payloads include different timing indicators. The SS blocks are received at different times separated by a time increment. The UE determines, based on the time increment, one or more hypotheses of combined decoding metrics for the first codeword and the second codeword, and decodes the first codeword based on each of at least one hypothesis in the one or more hypotheses. The at least one hypothesis includes a correct hypothesis. The UE determines the first codeword based on an error detection procedure such as CRC verification performed when decoding the first codeword based on the correct hypothesis.
