Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may utilize synchronization signal block (SSB) and channel state information reference signal (CSI-RS) based beam management to select beams for communicating with a base station. For example, a UE may receive, from a base station, control signaling that configures the UE to monitor a set of SSBs and a set of reference signals. The UE may select a subset of the set of SSBs based on measuring a first signal metric for each SSB of the set of SSBs. In some examples, the UE may select a reference signal subset of the set of reference signals that correspond to the subset of the set SSBs, and may communicate a data transmission with the base station using a first beam selected based on measuring a second signal metric for each reference signal in the reference signal subset.

Abstract: A signaling channel that punctures traffic channels is used to send signaling, e.g., acknowledgments (ACKs). To send signaling, resources for the signaling channel are determined, e.g., based on a frequency hopping pattern. Signaling is spread with a spreading code (e.g., a Walsh code) to generate spread signaling, which is mapped to the resources for the signaling channel. Each resource may be partitioned into multiple clusters. A signaling message may be mapped to different clusters to achieve diversity. Traffic data may also be mapped to other resources for a traffic channel assigned for use. Traffic data mapped to the other resources for the signaling channel is punctured. The mapped signaling and traffic data are further processed (e.g., for OFDM or SC-FDMA) and transmitted.

Abstract: Methods, systems, and devices are described for wireless communication. In one method, a method of wireless communication at a user equipment (UE) includes receiving a synchronization signal. The synchronization signal may be common to a plurality of cells within a network. The method further includes acquiring a timing of the network based on the synchronization signal, and transmitting a pilot signal in response to acquiring the timing of the network. The pilot signal may identify the UE and be concurrently receivable by the plurality of cells within the network. Other aspects, features, and embodiments are also claimed and described.

Abstract: The disclosure relates to reduced signaling to carry out the linking between new radio (NR) carrier aggregation (CA) band combinations and NR band processing combinations (BPCs), and includes apparatus and methods of receiving, at a modem of a user equipment (UE), a UE configuration from a base station based on UE band combination constraint information, configuring the UE, by a processor of the UE, according to the UE configuration, and performing a communication with the base station, via the modem of the UE, according to the UE configuration. In an implementation, the disclosure includes transmitting the UE band combination constraint information, such as in the form of receiving a total number of layers supported in a CA band combination, and wherein receiving the UE configuration further comprises receiving a CA combination and a BPC configuration in response to the UE band combination constraint information.

Abstract: Methods, systems, and devices for wireless communications are described that identify a minimum gap between a control channel transmission on a first component carrier (CC) that triggers a measurement report and an associated reference signal transmission on a second CC. The minimum gap may be based on a resource associated with a control channel transmission and a resource associated with the reference signal transmission. The first CC and the second CC have different numerologies and the minimum gap may be identified in terms of a number of OFDM symbols of the second CC that carries the reference signal transmission. The minimum gap also may be identified based on a location of the control channel transmission within a slot of the first CC. In cases where beam switching is used, the minimum gap may be further based at least in part on a beam switch time for performing the beam switching.

Abstract: Apparatuses and methods for performing asynchronous multicarrier communications are provided. One such method involves generating, at a first wireless device, a waveform including one or more carriers, shaping the waveform to reduce interference between the waveform and adjacent waveforms, and transmitting, on a spectrum, the shaped waveform asynchronously.

Abstract: The present disclosure describes various examples of a method, an apparatus, and a computer readable medium for multi-state discontinuous reception (DRX) in wireless communications. For example, one of the methods described may include identifying, by a user equipment (UE), at least two states in connected mode, determining, by the UE, one or more triggers for transitioning between the at least two states, and transitioning, by the UE, from a first state of the at least two states to a second state of the at least two states in response to a determination of the one or more triggers. In an aspect, the transitioning comprises transitioning between cross-slot scheduling and same-slot scheduling, or between a narrow bandwidth and a wide bandwidth, or between a larger periodicity and a smaller periodicity for monitoring.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may implement cross-carrier scheduling. A user equipment (UE) may identify a minimum scheduling delay and may receive a downlink grant on a first CC. The UE may further identify the slot in which a downlink data transmission corresponding to the downlink grant will be received, and may identify the slot such that the minimum scheduling delay is satisfied. The UE may the receive the downlink data transmission, as indicated in the downlink grant, in the identified slot. In some examples, the UE and the base station may alternate between a long minimum scheduling delay and a short minimum scheduling delay. In some examples, the UE and the base station may alternate between a cross-carrier mode, and a self-scheduling mode.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform calibration of a transceiver chain to maintain or improve operation of a device or comply with legal or protocol requirements. The UE may receive one or more wireless signals indicating a first set of resources where the first device is scheduled to transmit or receive communications. The UE may calibrate a wireless transceiver chain of the first device in a second set of resources. The second set of resources excludes the first set of resources and includes at least a portion of a third set of resources. The third set of resources are resource in which the first device has an option to transmit or receive communications based on a protocol configuration.

Abstract: Methods, systems, and devices for wireless communication between a first wireless device and a second wireless device are described. A second wireless device may determine that a channel condition satisfies at least one channel condition threshold. The second wireless device may identify, based on the determination, a time-interleaved transmission scheme for block(s) of encoded information. The second wireless device may transmit the block(s) of encoded information to a first wireless device in accordance with at least the time-interleaved transmission scheme. In some instances, the first wireless device may determine that the channel condition satisfies the at least one channel condition threshold and send a message to the second wireless device in order to trigger the use of the time-interleaved transmission scheme.
