Methods (), systems () and devices () for wireless communications are presented. A method () may include the following operations. A UE determines to perform a handover from a first source device in a first network to a first target device in the first network and from a second source device in a second network to a second target device in the second network (). The UE identifies a time interval for performing a first random access procedure with the first target device in the first network (). The UE initiates a first random access procedure with the first target device (). The UE performs a second random access procedure successfully with the second target device in the second network during the time interval (). The UE transmits or receives from the target device in the second network before the UE finishes performing the first random access procedure with the first target device in the first network ().

Parallel handover and failure handling

Aspects of the disclosure relate to wireless communication utilizing a modulation and coding scheme that selectively or dynamically applies probabilistically-shaped coding (PCS) to modulate a transmitted waveform. A communication device may determine whether to apply PCS. If PCS is to be applied, the device can encode the message based on a systematic code; and if PCS is not to be applied, the device can encode the message based on a non-systematic code. Other aspects, embodiments, and features are also claimed and described.

Constellation shaping-related coding selection

Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently transmitting data and control information in a first RACH message to a base station as part of a two-step RACH procedure. In particular, rather than or in addition to transmitting data and control information in a physical uplink shared channel (PUSCH) in the first RACH message, a user equipment (UE) may transmit the data and control information along with a RACH preamble in a RACH occasion in the first RACH message (e.g., when the number of bytes of data or control information to be transmitted is low). Using these techniques, in some instances, the UE may transmit the data and control information in a first RACH message without transmitting the PUSCH, and the overhead associated with transmitting the PUSCH may be eliminated.

Random access channel occasion configuration

Aspects described herein relate to requesting suspending of a data session of a first when a device capable of communicating over multiple subscriptions switches from an active communication state if the first network to an active communication state in a second network. The device can also request resuming the data session based on switching back to active communication state with the first network.

Techniques for managing sessions in multiple-subscription wireless communications

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a medium access control layer message indicating a set of mappings between a set of pathloss reference signals and one of: a set of physical uplink shared channel identifiers, or a set of sounding reference signal identifiers; receive downlink control information activating a mapping of the set of mappings; and perform a pathloss measurement using a pathloss reference signal identified by the activated mapping. Numerous other aspects are provided.

Medium access control layer mapping for pathloss reference signal

This disclosure relates to methods, devices, and systems for wireless communications, and more particularly to aggregating physical uplink shared channel (PUSCH) resource units relating to a random access message. A user equipment (UE) may identify a random access message of a random access procedure. The random access message may include a random access preamble and a random access payload. The UE may aggregate multiple PUSCH resource units of a set of PUSCH resource units associated with one or more PUSCH occasions (POs) based on one or more of a payload size of the random access payload or a modulation and coding scheme associated with the random access payload. As a result, the UE may transmit the random access payload of the random access message on a PUSCH using time and frequency resources of the aggregated multiple PUSCH resource units over the one or more POs.

Aggregated uplink shared channel transmission for two step random access channel procedure

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure a bitmap in a medium access control control element (MAC-CE) to indicate beam failure information for one or more serving cells or one or more groups of serving cells. The UE may transmit the MAC-CE to a base station via at least one serving cell. Numerous other aspects are provided.

Techniques for configuring a MAC-CE bitmap for beam failure recovery

Various aspects of the present disclosure generally relate to certificate based application descriptors for network slice selection. In some aspects, a user equipment (UE) may receive a first certificate associated with obtaining a network slice for executing an application. The UE may transmit, to a device, a request for the network slice with the first certificate, and receive an indication that the network slice is available to the UE for the application, based at least in part on the request. Numerous other aspects are provided.

Certificate based application descriptors for network slice selection

This disclosure provides systems, methods and apparatuses for using a media access control (MAC) control element (CE) for dynamic RLC entities selection. In one aspect, a base station (BS) may generate and transmit the control message to a user equipment (UE) to identify active radio link control (RLC) entities, a primary RLC entity, or other parameters relating to packet data convergence protocol (PDCP) duplication-based communication. In this case, the UE may use the control message to select an RLC entity and may transmit protocol data units (PDUs) to the BS using a data radio bearer (DRB) and the selected RLC entity.

Control message for dynamic radio link control (RLC) entity selection

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a scheduling request to a base station using the dedicated uplink resources. The UE may transmit the scheduling request to indicate that a group of UEs requests uplink resources for an uplink data transmission. As a result, the UE may receive downlink control information from a base station which includes corresponding uplink resources allocated to the UE based on the scheduling request. The UE may use the allocated uplink resources to transmit uplink data to the base station.

Group scheduling requests and resource assignments

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an average energy level radiated by the UE over a time period. The UE may determine whether the average energy level radiated by the UE over the time period exceeds a maximum permissible exposure (MPE) limit. The UE may transmit, to base station, a medium access control (MAC) control element (MAC-CE) that includes information related to a power management maximum power reduction (P-MPR) applied at the UE and/or an uplink duty cycle in effect at the UE based at least in part on the average energy level radiated by the UE over the time period exceeding the MPE limit. Numerous other aspects are provided.

Techniques for signaling maximum permissible exposure backoff indication

Aspects described herein relate to configuring and selecting preamble and payload occasions for performing two-step random access procedures. Configurations on preamble occasions, payload occasions, association pattern between the occasions and synchronization signal block (SSB) beams, and the rules for selecting preamble and payload occasions for random access message transmission can be determined by the network and signaled to user equipment (UE). Based on the configurations and rules, UE can measure the link level quality and select possible preamble and payload occasions for one or more SSB beams achieving a threshold signal quality. Sets of one or more preamble occasions and one or more payload occasions can be further determined based on whether the preamble and payload occasion(s) can achieve a threshold transmission latency. The one or more preamble occasions and one or more payload occasions can be used to transmit random access messages in the two-step random access procedure.

Techniques for configuring random access occasions in wireless communications

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability report to a base station indicating a triggering offset. The base station may configure the UE with one or more channel state information (CSI) measurement resources and send downlink control information (DCI) that triggers an aperiodic CSI report for some of the CSI measurement resources. The UE may report CSI by measuring the CSI resources after the triggering offset. In some cases, CSI reporting related to the different codebook types (e. g., Type I, Type II) may be modified, where after identifying a type of codebook and determining which type of codebook to process (e. g., based on a number of CSI processing units), the UE may identify a priority associated with different CSI reports. The UE may be configured with various parameters that relax or modify the processing of Type II CSI reports.

Techniques for simplifying channel state information feedback

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.
