Abstract: Various aspects described herein relate to techniques for mobility mode selection in uplink-based and downlink-based mobility in wireless communications systems. In an aspect, a method for wireless communications may include determining that a user equipment (UE) is operating in a first mobility mode, determining whether the UE satisfies at least one condition associated with mobility of the UE for mobility mode selection, and selecting a second mobility mode based on a determination that the UE satisfies the at least one condition, wherein each of the first mobility mode and the second mobility mode is an uplink mobility mode or a downlink mobility mode. The techniques described herein may apply to different communications technologies, including the 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Certain aspects of the present disclosure provide techniques for a slot format indicator (SFI) and slot aggregation level indication in a group common physical downlink control channel (GC PDCCH) and conflict handling for the SFI. According to certain aspects, a method of wireless communication by a base station (BS) is provided. The BS can determine a slot aggregation level and a format of the aggregated slots and send a downlink control channel including a SFI indicating the format of the aggregated slot and an indication of the slot aggregation level. The UE can receive the downlink control channel including the SFI and the indication of the slot aggregation level and the UE can determine a format of a current slot based on the received SFI and slot aggregation level.

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: 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: Aspects relate to activation of a cell (e.g., an SCell) based on measurements made by a user equipment (UE) when the cell is not activated with respect to (e.g., as a secondary cell for) the UE (e.g., the cell is deemed by the network as an unknown cell for that UE). In this case, when the network requests the UE to conduct measurements with respect to that cell (e.g., in conjunction with activation of the cell), the UE may report information based on the measurements the UE conducted when the cell was not activated with respect to that UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying a set of possible paging occasions and a set of connected mode communications. The UE may receive paging in a paging occasion, of the set of possible paging occasions, for which there is not a collision between the paging occasion and the set of connected mode communications and that is selected from the set of possible paging occasions based at least in part on a power utilization characteristic. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, while in dual connectivity with a carrier of a second cell group, a first grant for a first communication on a carrier of a first cell group. The UE may determine an allocated power for the first cell group by a specified time offset before a start of second cell group transmissions. The UE may receive a second grant, after the first grant, for a second communication on the first cell group. The UE may transmit the first communication with a first transmit power. The UE may transmit the second communication with a second transmit power that is based on the allocated power and the first transmit power and/or a maximum transmit power for the first cell group. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for downlink control information (DCI) communication and processing. One example method generally includes determining a limit, between a transmission time of a control channel carrying a DCI of a plurality of DCI and a time of an event enabled by the DCI, of a quantity of the plurality of DCI in a frame, generating a frame comprising the plurality of DCI in accordance with the determined limit, and transmitting the frame to a user-equipment (UE).

Abstract: Apparatus, methods, and computer program products for DL power allocation in inter-band CA with carriers with no SSB transmissions are provided. An example method may include receiving, from a second network node, SSB transmit power information for at least one carrier of a set of carriers, where the set of carriers may be associated with inter-band carrier aggregation, and where the SSB transmit power information may be indicative of an SSB transmit power or an SSB transmit power offset. The example method may further include determining a set of CSI-RS EPREs based on the SSB transmit power information for the at least one carrier, where the set of CSI-RS EPREs corresponds to a CSI-RS transmission in a first carrier of the set of carriers, where the first carrier is configured without SSB transmission.
