Abstract: This disclosure provides techniques for managing antenna sharing on a multi-mode wireless device between coexisting cellular and WLAN modems operating on the same band. One of the modems can communicate a WLAN scanning parameter to another one of the modems, and the distribution of shared antennas between the cellular modem and the WLAN modem may be modified based at least in part on the communicated scanning parameter to accommodate a WLAN scan on channels in the shared band. The distribution of the shared antennas between the modems for the WLAN scan may additionally or alternatively be selected based at least in part on the source of a detected WLAN scanning trigger (e.g., whether the scan is triggered by an application of the wireless device or the WLAN modem of the wireless device).

Abstract: Methods, systems, and devices for wireless communication are described. One method may include receiving, at user equipment (UE), a control resource set configuration message from a base station; identifying an overlap between a first control resource set and a second control resource set of a wireless channel; identifying a priority level of the first control resource set and a priority level of the second control resource set based on the control resource set configuration message; and monitoring the first control resource set based on the identified overlap, the priority level of the first control resource set, and the priority level of the second control resource set.

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.
