Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a limit on a number of concurrently active bandwidth parts, wherein the limit applies per component carrier used by the UE or across component carriers used by the UE. The UE may communicate using one or more bandwidth parts on one or more component carriers used by the UE based at least in part on the limit, wherein at least one bandwidth part of the one or more bandwidth parts is less than a full bandwidth that the UE is capable of using. 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 receive a first synchronization signal (SS) block that does not include remaining minimum system information (RMSI). The first SS block may indicate an offset for obtaining a second SS block that includes RMSI. The UE may determine a location of the second SS block based at least in part on the offset. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described that provide allocation of wireless resources for UEs in carrier aggregation resource groups that span two or more component carriers (CCs). A carrier aggregation resource group may include a portion of available wireless resources in two or more CCs, and multiple carrier aggregation resource groups may be configured that may include resources that span overlapping or non-overlapping CCs. Downlink control information may be transmitted using a downlink control region that spans two or more CCs in a carrier aggregation resource group. A UE may be configured to monitor multiple CCs for downlink control information, such as through blind decodes of each CC that may contain downlink control information.

Abstract: Methods, systems, and devices for wireless communication are described. A discontinuous reception (DRX) periodicity may be configured to enable monitoring of a reference signal (RS) for RLM procedures. For example, a transmitting device may configure a DRX periodicity for an RS, where the configured DRX periodicity may include a periodicity of discrete transmissions of the RS or a periodicity of a transmission window in which the RS is located. Accordingly, a receiving device may identify the DRX periodicity and monitor radio link quality using the RS based on the DRX periodicity. In some examples, the RS may be transmitted independent of control channel transmissions, and the transmitting device may configure one or more control resource sets for the RS.

Abstract: Aspects of the present disclosure provide various methods and apparatuses configured to reuse, reallocate, reserve, or reassign available control resources in a control region for carrying downlink (DL) payload or user data. The inventive concept and idea may also be applied to reuse control resources for uplink (UL) and/or sidelink user data transmission in both frequency division duplex (FDD) and time division duplex (TDD) configurations in other embodiments.

Abstract: User equipment (UE)-specific information may be transmitted within a control resource set configured to carry resources common to UEs within a system. The UE-specific information may be associated with a search space having an aggregation level different from aggregation levels used with the common control resources and may occupy different modulation symbols within the common control resource set (e.g., to support flexible scheduling for multiple UEs). A base station and UE may operate in a system using one or more control resource sets within a system bandwidth. The UE may detect common control resources by monitoring decoding candidates in the control resource set according to a first set of aggregation levels. The UE may detect UE-specific control resources by monitoring decoding candidates in the control resource set according to other aggregation levels. The UE and base station may communicate based on control information obtained from the monitoring.

Abstract: Split synchronization signal configuration for unified synchronization channels and techniques for indicating communication block boundaries in wireless communication systems that use a unified synchronization signal configuration that may be used in different communication modes are described. The disclosed split synchronization signal configuration allows the same synchronization signal configuration to be used in different communication modes (or numerologies) that operate on different frequencies. The boundary indication techniques of embodiments allow efficient indication of the beginning of a communication block (such as a frame, subframe, or slot) relative to the beginning of a unified synchronization signal configuration.

Abstract: A method and apparatus for decoupling of a synchronization (“sync”) channel raster and a channel raster in a wireless communication system is disclosed. For example, the method and apparatus include determining, at a network entity, a synchronization channel raster corresponding to a set of frequencies, and transmitting, from the network entity, one or more synchronization signals and a physical broadcast channel (PBCH) in any frequency of the set of frequencies of the synchronization channel raster to at least one UE. For example, the method and apparatus further include determining, at a network entity, a synchronization channel raster corresponding to a set of frequencies, and transmitting, from the network entity, one or more synchronization signals and a PBCH in a frequency of the set of frequencies of the synchronization channel raster closest to a center frequency of a bandwidth to at least one UE.

Abstract: Methods, systems, and devices for wireless communication are described. A method may include receiving a control transmission from a base station, identifying a control channel search space organized according to a nested structure, the control channel search space including a plurality of control channel candidates associated with one or more control channel elements (CCEs) and an aggregation level, and searching the received control transmission to identify a control channel for the UE using the plurality of control channel candidates. Another method may include determining whether to reorder resource element group (REG) indices for a received control channel transmission based, at least in part, on a transmission mode associated with the control channel transmission. Another method may include decoding a received control channel transmission, where the downlink control information (DCI) formats may be constrained to an integer multiple of a predetermined base number of bits N.
