Abstract: Certain aspects of the present disclosure provide techniques for wireless communication scheduling. An example method that may be performed by a user equipment (UE) includes receiving, from a base station, one or more configurations indicating wireless communication resources including at least one of a plurality of bandwidth parts (BWP) or a plurality of component carriers (CCs); receiving, from the base station, control signaling indicating a scheduling offset to communicate with the base station via at last one of the BWPs within at least one of the CCs; determining a value of the scheduling offset based at least in part on a minimum scheduling offset value; and taking at least one action in response to the determination.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a mapping between synchronization signal blocks (SSBs) and a random access message of a two-step random access procedure based on an indication in system information signaling or radio resource control (RRC) signaling. The random access message may include a random access preamble and a random access payload. The UE may determine, based on the mapping, an association between one or more beams carrying the SSBs and one or more additional beams carrying the random access preamble and the random access payload of the random access message. As a result, the UE may perform the two-step random access procedure with a base station according to the beam association, and coexist with a four-step random access procedure in a more reliable and efficient manner.

Abstract: Wireless communications systems may employ shared control resource set (CORESET) configurations for control information monitoring by a user equipment (UE) in an inactive state (e.g., for wake-up signal (WUS) monitoring) and for control information monitoring by a UE in an active state (e.g., for physical downlink control channel (PDCCH) monitoring). Further, a shared CORESET configuration may support one or more dynamic or variable configuration parameters, such that a shared CORESET configuration may be partially modified to optimize control information monitoring in different scenarios (e.g., to optimize WUS monitoring and PDCCH monitoring when using a shared CORESET configuration). For example, a CORESET configuration may include one or more static configuration parameters (e.g., a time resource, a frequency resource, a transmission configuration indicator (TCI) state, etc.) and one or more dynamic configuration parameters (e.g., an interleaving pattern, a precoding granularity, a time duration, a scrambling identification, etc.).

Abstract: A UE receives a first indication of a Wake-Up Signal (WUS) resource for another UE. The UE identifies a conflict between a resource allocated to the UE and the WUS resource for the other UE based on the first indication. The UE modifies communication with a base station in the resource in response to the identifying of the conflict. A base station identifies a conflict between a resource for communication with a first UE and a WUS for another UE and modifies the communication with the first UE in the resource in response to identifying the conflict.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a downlink configuration including a set of resources for receiving downlink transmissions. The UE may determine, based on the downlink configuration, an uplink configuration including a set of resources for transmitting scheduling requests at a set of scheduling request occasions. In some aspects, the set of scheduling request occasions may be arranged according to a non-uniform spacing pattern in the time domain. The UE may transmit, to a base station, one or more scheduling requests based on the uplink configuration.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to reference signal (RS) designs that allow for tracking loop updates and paging of UEs using various RSs. One example method includes identifying reference signal (RS) monitoring occasions for a user equipment (UE) in an idle or inactive mode; and transmitting, to the UE, reference signals in the identified RS monitoring occasions, the RS monitoring occasions being associated with RS for tracking purposes and RS for an indication the UE is to wake up to process additional signaling.

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.

Abstract: The present disclosure provides for enhanced pipeline processing using different timing characteristics for aggregated carriers. A receiving device may receive a first component carrier and a second component carrier from a transmitting device during a subframe including a first set of symbols on the first component carrier and a second set of symbols on the second component carrier. The first component carrier may be a priority component carrier having a different timing characteristic than the second component carrier. The receiving device may process, using a hardware processing pipeline, the first set of symbols interleaved with the second set of symbols. The receiving device may transmit an acknowledgment, within the subframe, based on the processing of at least all of the first set of symbols.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determining that a first physical downlink control channel (PDCCH) candidate and a second PDCCH candidate in a control resource set (CORESET) are aligned with each other, wherein the first PDCCH candidate is a common search space (CSS) candidate and the second PDCCH candidate is a UE-specific search space (UESS) candidate; and decode downlink control information in accordance with a selected candidate, of the CSS candidate or the UESS candidate, based at least in part on a rule indicating whether the time-domain resource allocation is to be determined in accordance with the CSS candidate or the UESS candidate. Numerous other aspects are provided.
