Abstract: Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.

Abstract: Methods, systems, and devices for wireless communication are described. A first wireless device may receive a clear to send signal based precoded based at least in part on a receive filter at a second wireless device. The first wireless device may calculate a transmit precoder based at least in part on the clear to send signal. For example, the first wireless device may calculate a whitening filter and a second filter based at least in part on the clear to send signal. The first wireless device may transmit a request to send signal precoded by the transmit precoder to initiate communications with a third wireless device without significantly interfering with ongoing communications at the second wireless device.

Abstract: A base station may determine a Doppler metric associated with a wireless channel and a user equipment (UE). The Doppler metric may be determined from received information related to Doppler effects measured by the UE or from directly measured Doppler effects associated with uplink data received from the UE. Based on the determined Doppler metric, the base station may select one or both of a reference signal (RS) density and a channel estimation technique for the wireless channel and associated UE. The base station may transmit an indication of the RS density to the UE. Downlink data bursts and uplink data bursts may include RSs and data according to the indicated RS density. Further, the base station may transmit to the UE, an indication to communicate using the selected wireless channel estimation technique.

Abstract: Reference signal and transmitter (Tx)/receiver (Rx) precoding for user equipment (UE) multiplexing in new radio (NR) shared spectrum networks is discussed. In certain reference signals, a base station may schedule multiple UEs for transmission of uplink reference signals within an identified subframe. The base station may transmit a reference signal configuration message, wherein the reference signal configuration message includes a transmission sequence identifier identifying a multiplexing for antenna ports assigned for transmission of the uplink reference signals. The multiplexing may be one or both of frequency divisional multiplexing (FDM) and time division multiplexing (TDM) over the identified subframe. Additional reference signals, transmit precoders may be identified by the base station based on channel inversion calculations of the channel matrix determined based on uplink reference signals.

Abstract: Techniques for synchronization across transmitting nodes of a same public land mobile network (PLMN) operator using a shared radio frequency spectrum band may include initiating, at a first wireless node, a listen-before-talk (LBT) procedure for access to the shared radio frequency spectrum band, and identifying that a second wireless node associated with a same PLMN operator as the first wireless node has won contention for the shared radio frequency spectrum band. The first wireless node may discontinue the LBT procedure and initiate an auxiliary transmission using the shared radio frequency spectrum band concurrently with a primary transmission of the second wireless node.

Abstract: Methods and apparatuses for transmitting and detecting channel reservation preamble in a NR shared spectrum are described. An aspect may include determining whether a first reservation preamble of a first operator is received on a first time slot of multiple time slots of a downlink channel from a first network entity, and transmitting a second reservation preamble of the first operator on an uplink channel to the second network entity. Another aspect may include generating a first reservation preamble of a first operator based on at least one of a compressed representation in a signal space, a basis function of the signal space, or a CAZAC sequences; and transmitting, on a first times lot of multiple time slots of a downlink channel, the first reservation preamble of the first operator to at least a UE. In another aspect, the SFN transmission of the first and second reservation preambles, and the low latency detection methods of the reservation preambles have been disclosed.

Abstract: TECHNIQUES FOR ESTIMATING AND REPORTING CHANNEL QUALITY INDICATOR (CQI) ARE DISCLOSED. NEIGHBORING BASE STATIONS MAY CAUSE STRONG INTERFERENCE TO ONE ANOTHER AND MAY BE ALLOCATED DIFFERENT RESOURCES, E.G., DIFFERENT SUBFRAMES. A UE MAY OBSERVE DIFFERENT LEVELS OF INTERFERENCE ON DIFFERENT RESOURCES. IN AN ASPECT, THE UE MAY DETERMINE A CQI FOR RESOURCES ALLOCATED TO A BASE STATION AND HAVING REDUCED OR NO INTERFERENCE FROM AT LEAST ONE INTERFERING BASE STATION. IN ANOTHER ASPECT, THE UE MAY DETERMINE MULTIPLE CQI FOR RESOURCES OF DIFFERENT TYPES AND ASSOCIATED WITH DIFFERENT INTERFERENCE LEVELS. FOR EXAMPLE, THE UE MAY DETERMINE A FIRST CQI BASED ON AT LEAST ONE FIRST SUBFRAME ALLOCATED TO THE BASE STATION AND HAVING REDUCED OR NO INTERFERENCE FROM THE INTERFERING BASE STATION(S). THE UE MAY DETERMINE A SECOND CQI BASED ON AT LEAST ONE SECOND SUBFRAME ALLOCATED TO THE INTERFERING BASE STATION(S). (FIGURE 6)

Abstract: Methods, systems, and devices for wireless communication are described that may perform dual stage channel interleaving in which code blocks are interleaved at the code block level and at a symbol level. The interleaved code block data may provide time diversity for the code block data, and the interleaved symbol data may provide frequency diversity for the code block data, thus helping to mitigate narrowband and/or bursty interference. The interleaving within the code block and interleaving within the symbols, in some examples, may allow pipelined implementation of decoding of the code blocks at the receiver, for faster processing. In some cases, systematic data and parity data may be interleaved within the code block data to provide a uniform distribution of the systematic data in time within the code block.

Abstract: A control channel transmission may include information for downlink transmissions, and another control channel, such as a physical micro sleep indicator channel (PMSICH), may include information for uplink transmissions that a user equipment (UE) may use to enter a power-saving micro sleep state. A base station may drop PMSICH transmissions in the event that downlink resources are constrained. A UE that receives a PMSICH transmission may determine an uplink transmission duration, and enter a micro sleep state for all or a portion of the uplink transmission duration.
