Abstract: Tracking reference signal designs for deployments without continuous reference signal transmission are described. The tracking reference signals may be extended in the frequency domain from a synchronization signal block and may occupy a subset or all of the symbol periods of the synchronization signal block. The tracking reference signals may have the same subcarrier spacing as synchronization signals and may be punctured in the frequency domain. Alternatively, the tracking reference signals may include common control reference signals transmitted periodically with paired reference signals in a data channel. The common control reference signals and paired reference signals may be transmitted regardless of the presence of control or data. For improved tracking after a transition to a connected mode or a long discontinuous reception (DRX) cycle, a slot including tracking reference signals may be repeated or an additional tracking reference signal pattern may be transmitted.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may determine to configure a user equipment (UE) to operate in a transmission/reception point (TRP) mode, wherein the TRP mode is a single-TRP mode or a multi-TRP mode. The BS may configure the UE to operate in the TRP mode based at least in part on a bandwidth part (BWP) switch or a trigger to switch between the multi-TRP mode and the single-TRP mode within a BWP. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine that a threshold is satisfied with regard to a search space set mapping, for a plurality of search space sets, for a slot of a downlink control channel, wherein the threshold relates to at least one of: a slot-based control channel element limit, or a slot-based blind decode limit; and perform a mapping of or monitor a subset of search space set occasions, of a search space set of the plurality of search space sets, in the slot in connection with determining that the threshold is satisfied. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE is to switch from a first active bandwidth part to a second active bandwidth part; determine a configuration for a second reference signal of the second active bandwidth part based at least in part on a configuration for a first reference signal of the first active bandwidth part; and receive the second reference signal based at least in part on the configuration for the second reference signal. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive when operating in a network that provides synchronization signals at a plurality of locations in a channel bandwidth, a common search space (CSS) indicator for a synchronization signal, wherein the CSS indicator indicates that the synchronization signal is not associated with a CSS for a downlink control channel. The user equipment may determine a location of the CSS for the downlink control channel based at least in part on the CSS indicator. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to efficient data scheduling in systems having a supplemental uplink carrier (SUL) configured. In some aspects, a method for wireless communications by a user equipment (UE) is provided. The UE receives signaling configuring the UE for uplink control channel transmission on a primary uplink carrier (PUL) or a SUL. The SUL is an uplink carrier not paired to a downlink carrier. The UE monitors in at least one search space for downlink control information (DCI) scheduling the UE for uplink data transmission to a cell on the PUL or the SUL. The UE sends one or more uplink data transmissions to the cell on the primary uplink carrier or the supplemental uplink carrier based on the DCI.

Abstract: Aspects and techniques relate to scheduling resources for uplink transmissions in wireless communication systems. In some examples, an allocation of resources for uplink may be based on a common reference resource (e.g., a reference physical resource block, PRB) also used for allocation of resources for downlink In other examples, allocation of resources for uplink may be based on a different reference resource. A scheduler may further provide an indication whether the same, common reference resource is used, or a different reference resource. A scheduler may further indicate a different reference resource as needed. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive scheduling information for a transmission associated with a particular radio access technology (RAT) of a 4G RAT or a 5G RAT, wherein the scheduling information identifies a particular resource of one of a first set of resources for the 4G RAT or a second set of resources for the 5G RAT, wherein one or more resources of the first set of resources are guaranteed for the 4G RAT based at least in part on a reference 4G time division duplexing (TDD) configuration, and wherein the one or more resources of the first set of resources and the second set of resources do not overlap in a time domain; and transmit or receive the transmission using the particular resource. Numerous other aspects are provided.

Abstract: Aspects of the present disclose provide various methods and apparatuses for communicating, controlling, and configuring component carrier and bandwidth part (BWP). A scheduling entity receives a capability report from a user equipment (UE). The capability report indicates a capability of the UE to utilize at least one of carrier aggregation (CA) or one or more bandwidth parts. The scheduling entity transmits a command to the UE to reconfigure at least one of a CA configuration or a bandwidth part (BWP) configuration. The scheduling entity determines an anticipated response timing of an acknowledgment (ACK) of the command based on the capability report received from the UE. The scheduling entity receives the ACK according to the anticipated response timing.
