Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether an uplink communication for a first radio access technology (RAT) has been dynamically scheduled or semi-statically configured, wherein the UE is in a dual connectivity mode using the first RAT and a second RAT. The UE may identify an uplink subframe for transmission of the uplink communication based at least in part on whether the uplink communication has been dynamically scheduled or semi-statically configured, and based at least in part on a downlink-reference uplink-downlink configuration. The UE may transmit the uplink communication in the identified uplink subframe. Numerous other aspects are provided.

Abstract: In a legacy gNB (e.g., pre-Rel. 17 gNB), RC UEs with only 1 or 2 receive antennas may have a geographic coverage area for control data and traffic data that is smaller than their geographic coverage area for SSB with respect to certain legacy gNBs. By contrast, at least some new gNBs (e.g., Rel. 17+ gNBs) have the capability to provide uniform geographic coverage for RC UEs with respect to SSB, control data and traffic data. In an aspect of the disclosure, a particular class of UEs (such as RC UEs) is steered towards particular cells (e.g., Rel. 17+ gNBs) via one or more biased class-specific cell selection parameters included in system information from the cells.

Abstract: A base station apparatus communicates using a first Radio Access Technology (RAT). The apparatus determines a combined Time Division Duplex Uplink/Downlink (TDD UL/DL) configuration for a User Equipment (UE) based on a first TDD UL/DL configuration for a first cell using the first RAT and a second TDD UL/DL configuration for a second cell using the first RAT. The apparatus sends an indication of the combined TDD UL/DL configuration to at least one of the UE and a second base station that uses a second RAT to communicate with the UE

Abstract: Methods, systems, and devices for wireless communication are described. In an aspect, a base station may determine a configuration of a first radio access technology (RAT) including a plurality of parameters associated with a plurality of first channels of the first RAT. The base station may also transmit a second channel associated with a second RAT different from the first RAT, the second channel overlapping with the first channels. In another aspect, a user equipment may receive a configuration of a first RAT including a plurality of parameters associated with a plurality of first channels of the first RAT. The UE may also receive a second channel associated with a second RAT different from the first RAT, the second channel overlapping with the first channels.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may determine at least one of a variable random access response (RAR) window start time, a variable maximum quantity of slots for an index of a first slot of a physical random access channel occasion, or scheduling information related to one or more variable delays for an uplink transmission. The BS may transmit, to a user equipment, at least one of information that identifies the RAR window start time, information that identifies the variable maximum quantity of slots, or the scheduling information. 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 determine, based at least in part on a decomposition rule for a discrete Fourier transform (DFT) block, a plurality of decomposition groups for tones, corresponding to a plurality of antenna ports of the UE, of a transmission. The UE may map the tones to the plurality of decomposition groups for transmission processing, and transmit, using the plurality of antenna ports, the transmission based at least in part on transmission processing. Numerous other aspects are provided.
