Methods, systems, and devices for wireless communications are described. Generally, a base station may configure a user equipment (UE) with a time to trigger (TTT) and a signal quality threshold. The UE may determine whether one or more conditions are satisfied, and if so, transmit an early measurement report or ignore a conflicting procedure that renders the measurements unavailable. In some examples, a UE may receive an indication of a minimum TTT in a configuration message with the TTT and the signal quality threshold. The UE may indicate an updated timing, to a base station, based on the minimum TTT. In some examples, the base station may determine that a UE is a multi-subscriber identification module (MSIM) UE, and may configure the duration of the TTT accordingly.

Measurement reporting timing adjustments

Aspects of the disclosure relate to mechanisms for enhancement in UE cell selection to prioritize cells supporting 5G New Radio (NR) in standalone mode (SA) and in non-standalone (NSA) mode. In some examples, a UE may identify a plurality of cells within an area including a location of the UE. Each cell supports at least one radio access technology (RAT) and at least one frequency. The UE may determine a selection order of the plurality of cells based on the supported RATs and frequency bands to prioritize cells supporting the latest RAT (e.g., 5G NR) and select a serving cell based on the selection order.

UE enhancement prioritizing 5G NR cell selection

An apparatus for receiving wireless communication at a first UE from a first wireless device may include a memory and at least one processor coupled to the memory. The memory and the at least one processor may be configured to receive a user grouping identifying a second UE that communicates with a second wireless device. The memory and the at least one processor may be further configured to receive a control transmission between the second UE and the second wireless device indicating a modulation and coding scheme (MCS) and allocated resources for the second wireless device. The memory and the at least one processor may be further configured to apply interference cancellation on at least one of a resource element (RE) or a resource block (RB) received from the first wireless device based on the MCS and allocated resources for the second wireless device.

Transmission coordination to mitigate interference

A method for wireless communication at a user equipment (UE) includes receiving, from a base station, multicast data via a multicast channel. The method also includes transmitting, to the base station, multicast feedback based on receiving the multicast data. In some examples, the multicast feedback is associated with a group of UEs including the UE. The method further includes receiving, from the base station, a re-transmission of the multicast data on the multicast channel or a unicast channel based on one or more of a number of UEs served by the base station, a number of UEs from the group of UEs providing the multicast feedback, or a radio channel condition.

Multicast radio bearer (MRB) with radio link control (RLC) re-transmission

Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for sending, from an upper layer at a transmitting device to a lower layer at the transmitting device, an indication by which the lower layer determines that a packet is to be transmitted as either an initial transmission or as a retransmission. The lower layer at the transmitting device may then determine a transmission process for transmitting the packet based on the indication, and the transmitting device may transmit the packet in accordance with the transmission process. Because the lower layer may identify whether the packet is to be transmitted as either the initial transmission or the retransmission, the lower layer may adapt the transmission process to improve the chances that the packet is received by a receiving device or to limit overhead.

Assistance signaling for radio link control retransmissions

Disclosed are techniques for wireless communication. In an aspect, a network node configures a quality of service (QoS) profile comprising one or more file-level QoS parameters, wherein the QoS profile applies to one or more files associated with a service flow associated with a user equipment (UE), wherein each file of the one or more files comprises one or more protocol data units (PDUs), and wherein a header of each PDU of the one or more PDUs of the file includes a file identifier and a file type of the file, and enforces the QoS profile on the one or more files.

High bandwidth low latency cellular traffic awareness

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method for wireless communication includes determining, by a user equipment (UE), listen before talk (LBT) information associated with new radio-unlicensed (NR-U) operation of the UE. The method further includes transmitting, by the UE, a report including the LBT information. Other aspects and features are also claimed and described.

Radio access network (RAN)-centric data collection for new radio (NR)-unlicensed (U)

Methods, systems, and devices for wireless communications are described. In some examples, a wireless communications system may support machine learning and may configure a user equipment (UE) for machine learning. The UE may transmit, to a base station, a request message that includes an indication of a machine learning model or a neural network function based at least in part on a trigger event. In response to the request message, the base station may transmit a machine learning model, a set of parameters corresponding to the machine learning model, or a configuration corresponding to a neural network function and may transmit an activation message to the UE to implement the machine learning model and the neural network function.

Configuring a user equipment for machine learning

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a report for one or more two-step random access channel (RACH) procedures between the UE and a base station (BS), wherein the RACH report includes at least one of an indication of a quantity of message A (MsgA) payloads transmitted during the one or more two-step RACH procedures on each beam of one or more beams associated with the BS, an indication of one or more parameters associated with each MsgA communication transmitted during the one or more two-step RACH procedures, or an indication of whether a respective signal strength for each beam, associated with the one or more two-step RACH procedures, satisfies a signal strength threshold. The UE may transmit the report to the BS. Numerous other aspects are provided.

Two-step random access channel signaling

Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE. The apparatus may transmit, to at least one of a network node or a network entity, an indication of one or more future network slices, an indication of one or more current network slices, and/or an indication of one or more past network slices, the future network slices corresponding to network slices for potential future use by the UE, the current network slices corresponding to network slices that are currently used by the UE, the past network slices corresponding to network slices that were previously used by the UE. The apparatus may also receive, from the network entity, a response to the indication of the one or more future network slices, the indication of the one or more current network slices, and/or the indication of the one or more past network slices.

UE assistance information for slices

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may select, from a plurality of slot formats for supporting time division duplexing, a slot format for use during time division duplexing; transmit an information element that includes a half-slot slot-type to identify the slot format for use during time division duplexing; and communicate with a user equipment (UE) in a time division duplexing mode in accordance with the slot format. Numerous other aspects are provided.

Flexible time division duplexing configuration

Certain aspects of the present disclosure generally relate to methods and apparatus for performing minimization of drive test (MDT) operations. For example, certain aspects provide a method for wireless communication. The method generally includes receiving, at a radio access network (RAN), a measurement configuration to start a trace of a user-equipment (UE), determining a transition of the UE to an inactive state, and sending one or more messages to coordinate the trace of the UE or indicate that the trace has failed in response to the determination.

Techniques for performing minimization of drive test (MDT)

The disclosure relates to methods, devices, and systems for wireless communications. In some wireless communications systems, a base station may transmit a multicast message to a group of user equipment (UEs), and the UEs may provide feedback for the multicast message. In some implementations, the base station may configure the UEs to transmit feedback for multicast messages. In some example, the UEs may transmit group-negative acknowledgment (NACK) feedback information for multicast messages that are not successfully received at the UEs. In some other examples, each UE may be configured with UE-specific uplink control channel resources for transmitting hybrid automatic repeat request (HARQ) feedback for a multicast message. In some implementations, a UE may support feedback for both unicast and multicast messages. The semi-static codebook for unicast, multicast, or both may account for whether the UE is capable of concurrently receiving unicast and multicast messages in a slot.

Feedback for multicast and broadcast messages

This disclosure provides systems, methods, apparatus, and computer programs encoded on a computer storage media for providing user equipment mobility history information to a remote computing platform. In one aspect, a user equipment may store user equipment mobility history information in memory within the user equipment. The user equipment may determine whether a radio access network connection state has changed from a primary cell in a radio resource controller state to another cell outside a radio access network, to an inter-radio access technology cell, or to an out of service. The user equipment may transmit the user equipment mobility history information to the remote computing platform in response to determining that the user equipment radio access network connection state has changed from a primary cell in a radio resource controller state to another cell outside a radio access network, an inter-radio access technology cell, or an out of service state.

User equipment (UE) mobility history information management

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit assistance information indicating a type of in-device coexistence (IDC) interference at the UE, and indicating a set of associated interference parameters that correspond to an interference pattern of the IDC interference in a time domain, a frequency domain, or both. The set of interference parameters and the interference pattern may describe a pattern of the IDC interference in the time domain, the frequency domain, or both. The UE may receive a message indicating one or more operating parameters associated with a time period that is based on the interference pattern. The operating parameters may be based on the type of IDC, the set of interference parameters, and the interference pattern, and may enable the UE to communicate with a network entity to maintain signaling throughput while decreasing effects of the IDC interference.
