Abstract: Methods, systems, and devices for wireless communication are described. A base station may perform a Listen-Before-Talk (LBT) procedure to obtain access to a wireless communication channel. The base station may then determine a pattern of synchronization signal block (SSB) transmissions based on an outcome of the LBT procedure and transmit the pattern of SSB transmissions after obtaining access to the wireless communication channel. The outcome of the LBT procedure may include obtaining access to the wireless communication channel after a missed opportunity for at least one SSB transmission in a discovery reference signal (DRS) measurement timing configuration (DMTC) window. A user equipment (UE) may determine system timing based on a received SSB transmission.

Abstract: A method and apparatus for determining rate matching behavior for a plurality of control resource sets (CORESETs) is provided. A base station (BS) bundles a plurality of CORESETs into a global resource set. The BS configures the global resource set for a User Equipment (UE). The BS determines resources assigned to a downlink data channel overlap at least a portion of the global resource set and determines whether data on the downlink data channel is to be rate matched around the global resource set or is to use resources in the global resource set. The BS transmits the data on the downlink data channel based on the determination of the rate matching.

Abstract: Aspects of the disclosure relate to communication systems, apparatus and methods which enable or support transmitting/receiving downlink control information (DCI) carrying a downlink grant or an uplink grant. A method includes detecting a reference length based on an effective length of a downlink (DL) grant DCI and an effective length of an uplink (UL) grant DCI and calculating a length difference based on the effective DL grant DCI length and the effective UL grant DCI length. A length of a padding field in the DL grant DCI and/or the UL grant DCI is set equal to the calculated length difference such that the lengths of the DL grant DCI and UL grant DCI are both equal to the reference length. Padding bits are inserted in the padding field of the DL grant DCI and/or the UL grant DCI. Thereafter, the DL grant DCI and/or the UL grant DCI is encoded and transmitted to a scheduled entity.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a device may determine a shared demodulation reference signal (DMRS) configuration for a plurality of resource blocks of a channel, wherein a frequency domain associated with the plurality of resource blocks overlaps for a control resource of the channel and a data resource of the channel, and wherein the plurality of resource blocks are associated with a shared precoding scheme. The device may transmit a DMRS based at least in part on determining the shared DMRS configuration to enable a receiver to receive the plurality of resource blocks of the channel. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for mapping modulated symbols to physical resources. The mapping described herein may result in both time and frequency diversity. For example, a method for wireless communications may include alternately mapping quadrature amplitude modulated (QAM) symbols of a code block to frequency resources within a scheduling unit of time, wherein the mapping comprises a frequency-first mapping where symbols of the code block are alternately mapped to a first subset of the frequency resources in a first set of orthogonal frequency division multiplexed (OFDM) symbols, then to a second subset of the frequency resources in a second set of OFDM symbols, and transmitting the code block based on the mapping.

Abstract: Wireless communications systems and methods related to asynchronous medium sharing are provided. A first wireless communication device transmits a first channel reservation message to reserve a transmission opportunity (TXOP) in a shared spectrum. The first wireless communication device transmits a second channel reservation message during the TXOP. The first wireless communication device communicates, with a second wireless communication device, data over the shared spectrum during the TXOP.

Abstract: In an aspect of the disclosure an apparatus, e.g., a base station, maybe configured to receive, from a UE, ACK/NACK feedback indicating that a subset of CBGs of a set of transmitted CBGs failed to be properly decoded. The apparatus maybe further configured to retransmit the subset of CBGs based on the ACK/NACK feedback and transmit information indicating the CBGs being retransmitted. In one configuration, a TB of new data maybe transmitted with the retransmitted subset of CBGs in a subframe/slot. In an aspect, a UE may be configured to determine that one or more CBGs of a received set of CBGs failed to be properly decoded at the UE, and send ACK/NACK feedback indicating the one or more CBGs that failed to be decoded. The UE maybe further configured to receive a retransmission of CBGs in the set of CBGs, and information indicating the retransmitted CBGs.

Abstract: Techniques for a channel reservation signal design with a new radio (NR) physical downlink control channel waveform are provided. A method for wireless communication includes determining one or more orthogonal frequency division multiplexing (OFDM) symbols to transmit channel reservation signals, and determining a plurality of resources available for transmitting the channel reservation signals during the OFDM symbol(s). The method further includes selecting one set of resources within a plurality of resources to transmit a channel reservation signal, and transmitting the channel reservation signal in the selected set of resources to reserve a portion of spectrum for communication. Another method for wireless communication includes determining OFDM symbol(s) to monitor for channel reservation signals, determining a plurality of resources available for monitoring the channel reservation signals during the OFDM symbol(s), and monitoring for one or more channel reservation signals transmitted in a set of resources within the plurality of resources.
