Abstract: Methods, systems, and devices for wireless communication are described. A base station and user equipment (UE) may utilize different slot structures for communications depending on the type of data to be transmitted. A base station may configure the slot structures based on a capability of a UE or operation conditions. The base station may identify a slot structure for a first slot, which may be group-specific or UE-specific, and determine a slot structure for a subsequent slot, which may be UE-specific or based on the slot structure of the first slot. A set of slot structure combinations may be identified to be used by a UE for combining the first and subsequent slots, and one combination may be selected based on a capability of the UE, an operation to be performed by the UE, an operational condition associated with the UE, or a combination thereof.

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: Wireless communications systems and methods related to downlink (DL) control channel communications are provided. A wireless communication device identifies a search space set including a plurality of PDCCH candidate search spaces for a downlink control channel. The wireless communication device determines that a first resource associated with a first PDCCH candidate search space of the plurality of PDCCH candidate search spaces overlaps with a preconfigured resource. The wireless communication device monitors for a downlink control message over the downlink control channel by excluding monitoring in at least the first PDCCH candidate search space based on the determining.

Abstract: Techniques for implicitly configuring resources for radio link monitoring or beam failure detection. An example method generally includes identifying that RLM resources or BFD resources are configured implicitly by at least in part: obtaining TCI states, for PDDCH CORESETs, obtaining an indication that at least one of the TCI states is activated to become an active TCI state of the PDCCH CORESETs, identifying one or more CSI-RS resources configured in the at least one of active TCI states of the PDCCH CORESETs, and if the UE does not support RLM or BFD based on the CSI-RS or the one or more CSI-RS resources are AP or SP, determining a SS block for RLM or BFD that has a QCL relationship with the one or more CSI-RS resources of the at least one of active TCI states; and performing RLM or BFD based on the SS block.

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: Power control in new radio (NR)-to-NR dual connectivity communications is disclosed. A UE, compatible for NR-to-NR dual connectivity, may receive a transmit power configuration and a power allocation configuration. The transmit power configuration identifies the designated reserved power for each of the cell groups participating in the dual connectivity communication. The power allocation configuration identifies to the UE whether to operate access to excess transmission power by either mode 1 rules, which may introduce phase discontinuity into ongoing transmissions, or mode 2 rules, which use a look-ahead functionality to trigger joint determination and allocation of transmission power among known uplink transmissions over a given transmission duration. After the determined transmission power allocation has been made, the UE transmits the dual connectivity transmissions according to the determined power.

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: Improved methods, systems, devices, or apparatuses that support search space design are described. The described techniques enhance the number and utility of applied control channel candidates in the presence of blind decoding and control channel element (CCE) channel estimation limitations. The techniques allocate available blind decodes using a nested mapping scheme over one or more dimensions, based on a prioritization. In some other cases, the number of blind decodes may be allocated, either uniformly, or proportionally, between the plurality of search space set occasions. In some cases, the applied control channel candidates may be determined by dropping control channel candidates along one or more dimensions (e.g., search space set, or search space set occasion), until the blind decoding limitation or CE limitation is satisfied.

Abstract: A method of wireless communications at a user equipment (UE) includes receiving, from a serving cell associated with a wireless network, a radio resource management (RRM) mode indicator that indicates a set of one or more beams for which cell measurement and reporting is to be performed by the UE; performing at least one cell measurement on at least one synchronization signal (SS) block received from at least one neighboring cell; determining, based at least in part on the RRM mode indicator, whether to decode a physical broadcast channel (PBCH) received in each SS block of the at least one SS block; and transmitting a cell measurement report, the cell measurement report based at least in part on the at least one cell measurement, the cell measurement report selectively including at least one beam index based at least in part on whether the PBCH is decoded.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a modulation and coding scheme (MCS) for an uplink communication of the UE; identify a set of beta values for uplink control information of the uplink communication according to a mapping between the set of beta values and the MCS, wherein the set of beta values is for determination of a number of resource elements or modulation symbols for the uplink control information; and transmit the uplink control information based at least in part on the set of beta values. Numerous other aspects are provided.
