Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to system information acquisition over bandwidth parts (BWPs) in communications system operating according to new radio (NR) technologies. In an exemplary method, a user equipment (UE) receives system information (SI) via a transmission in a downlink (DL) bandwidth part (BWP) of a system bandwidth and transmits, to a serving base station (BS) and in response to receiving the SI, an indication that the UE has completed SI acquisition.

Abstract: Disclosed are techniques for enabling a user equipment (UE) operating in carrier aggregation mode to use different connected mode discontinuous reception (CDRX) configurations for different sets of component carriers associated with different sets of numerologies. For example, in Frequency 1 (FR1) plus Frequency 2 (FR2) carrier aggregation (i.e., one or more FR1 component carriers and one or more FR2 component carriers), a different CDRX can be configured for FR1 than for FR2. In inter-band carrier aggregation (i.e., one or more component carriers in one frequency band and one or more component carriers in another frequency band), CDRX can be configured per band. For mixed numerologies carrier aggregation (i.e., one or more component carriers with a first numerology and one or more component carriers with a different numerology), CDRX can be configured per cell group, where each cell group contains a single numerology or mixed numerologies.

Abstract: A method and apparatus for determining rate matching behavior for a plurality of control resource sets (CORESETs) is provided. A base station (BS) bundles a plurality of CORESETs into a global resource set. The BS configures the global resource set for a User Equipment (UE). The BS determines resources assigned to a downlink data channel overlap at least a portion of the global resource set and determines whether data on the downlink data channel is to be rate matched around the global resource set or is to use resources in the global resource set. The BS transmits the data on the downlink data channel based on the determination of the rate matching.

Abstract: Aspects of the present disclosure describe determining an uplink channel raster for determining frequency location of an uplink channel over which to transmit uplink communications to a base station. Uplink communications can be transmitted to the base station over the uplink channel. The uplink channel raster can be shifted, in frequency, with respect to a legacy uplink channel raster of a legacy communication technology to facilitate coexistence, in an uplink carrier, of the uplink channel and one or more uplink channels of the legacy communication technology.

Abstract: The present disclosure describes various aspects of the implementation and design of Physical Downlink Control Channel (PDCCH) in 5G new radio (NR) applications. Aspects include methods, apparatuses, and computer-readable medium for one or more of multiple PDCCH search spaces, control resource block (CRB), irregular multiple slots or mini-slots grants, or fast control channel signaling for grant-free uplink (UL). For example, different scheduling entities can each have one or two search spaces defined (e.g., common and/or user equipment (UE)-centric search spaces). Also, CRBs can be used as units for PDCCH transmission instead of resource element groups/control channel elements (REGs/CCEs). In addition, irregularities in time domain, frequency domain, or both can be introduced in the granting of resource blocks (RBs) over multiple slots or mini-slots. Moreover, signaling can be used to indicate to a UE configured for grant-free UL the portion of the pool of resources available for grant-free UL.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first hybrid automatic repeat request acknowledgement (HARQ-ACK) payload for a first component carrier (CC) set based at least in part on a first downlink assignment index (DAI). The UE may determine a second HARQ-ACK payload for a second CC set based at least in part on a second DAI. The UE may transmit the first HARQ-ACK payload for the first CC set and the second HARQ-ACK payload for the second CC set. 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 second communication, of a bandwidth part (BWP) selection process, that indicates a subset of BWPs, of a set of BWPs, to be selected as a set of active BWPs, wherein the set of BWPs is configured to the UE for a component carrier via radio resource control signaling as a first communication of the BWP selection process, wherein the subset of BWPs includes one or more BWPs of the set of BWPs. In some aspects, the UE may select the subset of BWPs as the set of active BWPs based at least in part on receiving the second communication, wherein a particular BWP, of the subset of BWPs, is to be used for a post-BWP selection process communication. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for allocating a number of physical downlink control channel (PDCCH) blind decoding candidates to a user equipment (UE) in dual connectivity mode. An example method generally includes allocating a resource budget among a first cell group and a second cell group, wherein the resource budget includes a number of physical downlink control channel (PDCCH) blind decoding candidates and a number of control channel elements (CCEs) supported by the UE, and monitoring for PDCCH candidates in the first cell group and second cell group in accordance with the allocated resource budget.

Abstract: Various aspects of the disclosure relate to use of a default communication configuration for cross carrier wireless communication. For example, a wireless communication device such as a user equipment (UE) may use a default communication configuration that includes quasi-colocation information (e.g., a default CORESET configuration) for communication on a secondary component carrier (SCC). The default communication configuration may be used, for example, in scenarios where a CORESET is not defined for the SCC and other configuration information is not available. For example, other configuration information might not be available due to a short time gap between a grant sent on a primary component carrier (PCC) and the communication on the SCC scheduled by the grant.
