Abstract: Certain aspects of the present disclosure provide techniques for service request (SR) prioritization for intra-UE (user equipment) ultra-reliable low-latency communication (URLLC) service and enhanced mobile broadband (eMBB) service multiplexing. Aspects provide a method for wireless communications by a UE. The method includes determining one or more transmission resources for one or more service requests (SRs) for a first type of service and/or a second type of service. The method includes determining one or more priority levels associated with the one or more transmission resources. The method includes transmitting the one or more SRs using the determined one or more transmission resources based on the associated priority levels.

Abstract: Methods, systems, and devices for wireless communications are described. A base station in a wireless communications system may perform a connection procedure (e.g. radio resource control (RRC) procedure) with a user equipment (UE), during which the base station may configure the UE with logical channel prioritization (LCP) configuration for each logical channel of a set of logical channels. The LCP configuration may indicate allowable modulation coding schemes (MCSs) for each logical channel of the set of logical channels. Following the communication procedure, the UE may receive an uplink grant for transmitting data using a corresponding logical channel of the set of logical channels. The UE may identify an MCS used by the uplink grant and may transmit the data using the corresponding logical channel with the identified MCS, based on the identified MCS of the uplink grant matching an MCS of the logical channel.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method of wireless communication includes determining, at a user equipment (UE), that a current data transmission to a network entity is complete. The method further includes transmitting, to the network entity and based on the determination, an indication to terminate a discontinuous reception (DRX) active time assigned to the UE. Other aspects and features are also claimed and described.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication that enables a UE to generate a PRACH message based on an SSB/CSI-RS for a first cell or first band and to transmit the PRACH message via another cell or another band. Aspects enable a base station to select an SSB index for transmitting downlink communication to the UE on the first cell/first band. A UE receives an SSB/CSI-RS from a base station through a first cell and transmits a random access message for the SSB/CSI-RS to the base station through a second cell. In another aspect the UE receives the SSB/CSI-RS from a base station through a first frequency range and transmits a random access message based on the SSB/CSI-RS to the base station through a second frequency range.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive system information from a base station indicating at least one configuration rule for power control parameter setting for random access. The UE may measure one or more reference signals and may estimate a path loss of wireless communications between the base station and the UE based on the measured reference signals. The UE may select one or more parameters from one or more sets of parameters indicated in the configuration rule. The UE may select a first transmit power for a preamble of a random access message and a second transmit power for a payload of the random access message, based on the estimated path loss and the configuration rule for power control parameters and power ramping procedures. The UE may transmit the random access message according to the selected first and second transmit powers.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques at a user equipment (UE) provide for efficiently identifying a dormancy state of a secondary cell (SCell) configured for communications with a base station. A UE may be configured with a duration of time for which an SCell is to be in an indicated dormancy state. Accordingly, when the UE receives an indication of a dormancy state for an SCell, the UE may determine that the SCell is in the indicated dormancy state for the duration of time. The UE may also be configured with a default dormancy state of the SCell. Thus, after the duration of time expires, the UE may determine that the SCell is in the default dormancy state (e.g., the UE may fall back to the default dormancy of the SCell after the duration of time expires).

Abstract: Aspects of the disclosure relate to mechanisms for dynamic prioritization of uplink (UL) traffic at a user equipment (UE). In some examples, the UE may determine to delay transmission of UL traffic by skipping one or more UL transmission opportunities based on one or more factors, such as a power saving indication, a priority level of the UL traffic, a type of the UL traffic, a volume of the UL traffic, and/or current channel conditions. In some examples, the UE may be configured with a parameter controlling the ability of the UE to delay a transmission of UL traffic. In some examples, when the UE is operating in a semi-persistent scheduling mode and a power saving mode, such as a connected mode discontinuous reception (C-DRX) mode, the UE may dynamically interrupt an OFF duration of the C-DRX cycle to transmit UL traffic.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a first sub-slot periodicity for downlink semi-persistent scheduling (SPS). The UE may receive a plurality of transmissions according to the first sub-slot periodicity in a first slot, wherein the first sub-slot periodicity enables receiving the plurality of transmissions within a single slot. The UE may transmit hybrid automatic repeat request acknowledgement (HARQ-ACK) information in a second slot, wherein the second slot includes a plurality of physical uplink control channels (PUCCHs) with a second sub-slot periodicity, and wherein the HARQ-ACK information is associated with the plurality of transmissions. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station during a connection establishment procedure, a UE message indicating support for a plurality of connected modes, where the plurality of connected modes includes a first connected mode. The UE may receive, based at least in part on the UE message, a configuration message from the base station configuring resources for the UE to use while operating in the first connected mode. The UE may perform a grantless communication with the base station while operating in the first connected mode and using the configured resources.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently signaling configurations of physical resources and transmission parameters to a user equipment (UE) for small data transmissions (for example, data transmissions in an inactive or idle state). A base station may broadcast or multicast downlink control information (DCI) in one or more control channels that schedules data transmissions in a set of data channels. The base station may then multicast one or more configurations in each of the data channels, and a UE may decode one of the data channels to determine a configuration for a small data transmission. Because the configurations may be transmitted in the data channels in addition to system information or paging information, a base station may have access to sufficient resources to provide suitable configurations to a UE for communications in an inactive or idle state.
