Abstract: Methods, systems, and devices for wireless communications are described. As described herein, a service type may be configured, activated, and utilized for subsequent communications according to the service type. For example, a user equipment (UE) may monitor a downlink control channel associated with the service type based on configuring the service type and activating the service type, receive downlink messages associated with the service type, or transmit uplink messages associated with the service type. In some cases, the service type may be activated by transmitting a medium access control (MAC) control element (CE) or a downlink control information (DCI) message. When traffic associated with the service type is no longer present, the service type may be deactivated based on a deactivation indication and/or a deactivation timer. In some cases, the service type may include an ultra-reliable low latency communication (URLLC) service or a low latency service.

Abstract: Aspects of the present disclosure provide a configurable bi-directional time division duplex (TDD) subframe structure. The configurable subframe structure includes a downlink control portion, an uplink control portion, an uplink data portion and a downlink data portion. A current subframe for communication between a scheduling entity and a set of one or more subordinate entities is produced by determining a desired ratio of uplink information to downlink information for the current subframe and configuring the configurable subframe structure with the desired ratio.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a downlink (DL) reception indication during an active duration of a discontinuous reception (DRX) configuration. The DL reception indication may indicate the presence of a reception opportunity following an inactivity interval, as well as the length of the inactivity interval. The wireless device may refrain from DL monitoring during the inactivity interval. In some cases, the wireless device may enter a sleep mode during the inactivity interval and wake up to receive a subsequent transmission during the reception opportunity. In some examples, the wireless device may use the inactivity interval to communicate using a different radio access technology (RAT).

Abstract: Methods, systems, and devices for wireless communications are described that provide for transmission of an indication of an activated bandwidth part (BWP) or component carrier (CC), or combination thereof, to a user equipment (UE) through downlink control information (DCI) that is excluding a grant of resources of the BWP or CC. A UE may establish a connection with a base station in which one or more CCs may be configured with one or more BWPs. The base station may indicate which BWP is active for a transmission in DCI that is transmitted subsequent to the configuration of the one or more CCs, and a UE may activate a corresponding BWP or CC based on the indication. In some cases, a CC may be deactivated unless the DCI indicates that at least one BWP of the CC is active.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive downlink control information within a control resource set (CORESET) configured with a wideband demodulation reference signal (DMRS) and including disjoint segments of resource blocks (RBs). The downlink control information may be located at least partially within a first segment of the disjoint segments and a second segment of the disjoint segments may be exclusive of the downlink control information. The downlink control information may include a grant of a set of resources for a downlink shared channel that overlaps with the CORESET. The UE may determine a rate matching operation for the wideband DMRS for a downlink shared channel for portions of the set of resources that overlap with the second segment of the disjoint segments, and receive the downlink shared channel on the set of resources according to the determined rate matching operation.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may obtain access to a base station by performing an initial access procedure within an initial access bandwidth that contains control channel resources. The UE may receive a configuration of a downlink bandwidth part (BWP) following the initial access procedure, and may determine that the downlink BWP fully contains the initial access bandwidth. In some cases, the UE may make the determination based on an indication sent from the base station. For instance, the indication may be provided as part of one or more control channel configurations transmitted to the UE. Based on determining that the downlink BWP fully contains the initial access bandwidth, the UE may monitor for control information in the downlink BWP using control channel resources in the downlink BWP that correspond to control channel resources used in the initial access bandwidth.

Abstract: Techniques are described for signaling a downlink bandwidth part (BWP) switching event and an aperiodic channel state information (A-CSI) request in a paired spectrum environment. The base station may transmit uplink scheduling downlink control information (DCI) to a user equipment (UE) that includes the A-CSI request and an identifier for the downlink BWP of the downlink BWP switching event. After receiving the A-CSI request and the downlink BWP, the UE may perform one or more CSI measurements using the downlink BWP. The UE may use physical uplink shared channel (PUSCH) resources associated with the uplink scheduling DCI to transmit the CSI report to the base station. Using these techniques, the base station may be configured to indicate that a downlink BWP switching event is to occur and allocate PUSCH resources to the UE to be used to transmit the CSI report associated with the downlink BWP switching event.

Abstract: Aspects of the present disclosure provide various wireless communication numerology designs that can maintain symbol boundary alignment while multiplexing different numerologies in wireless communication. The symbols may be scaled for different tone or subcarrier spacings while maintaining the symbol boundary alignment between different numerologies. Maintaining the symbol-boundary alignment between different numerologies enables symbol-level numerology multiplexing. The disclosed numerology designs enable low latency communication and improved interference management, and provide non-ambiguous symbol boundary timing reference for multiplexing different numerologies.

Abstract: Wireless communication devices, systems, and methods related to communicating CSI reports during a discontinuous reception (DRX) are provided. For example, a method of wireless communication may include performing one or more measurements of one or more reference signals configured for a user equipment (UE). The method may also include triggering transmission of a channel state information (CSI) report during a DRX cycle. The method may further include transmitting to a base station (BS), the CSI report based on the triggering, the CSI report including the one or more measurements.

Abstract: Generally, the described techniques provide for duplex mode configuration for control information (e.g., duplex mode configuration for communication of downlink control information). For example, duplex modes may be defined (e.g., as full duplex (FD) capable, FD only, half duplex (HD) only, etc.), and such duplex modes may be configured for control resource sets (CORESETs), search space (SS) sets, or both. In some examples, duplex modes configured for a CORESET/SS set may depend on the priority of information conveyed via the CORESET/SS set. For example, a CORESET/SS set for high priority or critical control information may be configured with a HD mode to avoid FD self-interference, while CORESET/SS set for other control information may be configured with a FD mode to improve spectrum efficiency. Techniques for resolving conflicting duplex mode configurations (e.g., when a HD mode is configured for a SS set within a CORESET configured with FD) are also described.
