Abstract: Certain aspects of the present disclosure provide a method for wireless communications at a user equipment (UE). The UE may generate a delay status report (DSR) for at least two traffic flows on different logical channels. The at least two traffic flows have a maximum synchronization threshold between each other. The DSR may include at least one remaining delay budget (RDB) parameter related to an RDB of at least one of a first traffic flow or a second traffic flow and the maximum synchronization threshold. The UE may transmit the DSR.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a network entity may output, and a user equipment (UE) may receive, a first control message identifying a first discontinuous reception (DRX) cycle and a second, different DRX cycle for the UE to use, the first and second DRX cycles having a first and second active duration, respectively. The network entity may also output a second control message identifying periodic resources for the UE to use to monitor for a periodic signal, the periodic resources being outside at least the first active duration. The UE may monitor for, and the network entity may output, based on the periodic resources being outside the first active duration, the periodic signal during the first active duration based on updating the first active duration, updating the periodic resources, or both.

A user equipment (UE) may measure the DRSs and identify one or more associated synchronization signal blocks (SSBs) that are to be requested. The UE may transmit a wake-up signal (WUS) that includes an identification of one or more requested SSBs, such as a codepoint or bitmap. The network entity may receive the WUS and transmit the requested SSBs.

Abstract: This disclosure provides methods, components, devices, and systems for optimizing energy efficiency and network performance in cellular networks through dynamic adaptation of transmission parameters for synchronization signal blocks (SSBs) and system information block type 1 (SIB1) transmissions initiated by user equipment (UE) requests. Some aspects more specifically relate to providing UE-assisted information over an uplink wake-up signal (UL-WUS) to optimize support of on-demand SSBs or SIB1s. In some examples, a UE sends an uplink signal to a network entity requesting transmission of at least one of an SSB or an SIB1, with the uplink signal indicating a transmission parameter for the SSB or the SIB1, such as transmission power or repetition factor. In response to the uplink signal, the network entity sends the SSB or the SIB1 associated with the transmission parameter based at least in part on the uplink signal, resulting in improved energy efficiency and network performance.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first indication of a first set of random access occasions (ROs) configured for the UE. The UE may transmit a second indication that the UE will refrain from using at least a portion of the first set of ROs. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) to transmit a physical uplink shared channel (PUSCH) occasion skipping uplink control information (UCI) on more than one transmit occasion of a configured grant (CG). For example, the PUSCH occasion skipping UCI may be associated with a priority, and the UE may multiplex the PUSCH occasion skipping UCI with a PUSCH transmission when the UE does not identify another UCI with a higher priority than the PUSCH occasion skipping UCI to multiplex with the PUSCH transmission. In some examples, the priority of the PUSCH occasion skipping UCI may decrease over time (e.g., with each successive slot). In some examples, the UE may identify a gap period, and may transmit a new PUSCH occasion skipping UCI when the gap period has passed.

Abstract: Apparatus, methods, and computer program products for flexible uplink transmission are provided. An example method may include receiving a configuration of resources for a PUCCH or a PUSCH associated with UCI, where the configuration of resources may be received from a network entity, where the UCI indicates a set of resources corresponding to a transmission in a first subset of resources associated with the PUSCH and a skipped transmission in a second subset of resources associated with the PUSCH or indicates an MCS for the PUSCH, where the UCI would overlap with an uplink transmission, where the set of resources may include the first subset of resources and the second subset of resources. The example method may further include transmitting at least one of the UCI or the uplink transmission to the network entity.

Abstract: Some techniques described herein provide autonomous modification of a modulation and coding scheme (MCS) of a grant for a transmission by a user equipment UE. For example, the UE may receive a grant (e.g., a configured grant) indicating a resource allocation and a first MCS for a transmission on the resource allocation. The UE may use the resource allocation for a transmission of a number of transport blocks (e.g., one or more transport blocks), and may use a second MCS, different than the first MCS, for the transmission. In some examples, the second MCS may be a lower MCS, associated with a lower modulation scheme and/or code rate, than the first MCS. Thus, a per-resource-block power consumption of the transmission is decreased by using the second MCS, which provides power savings while reducing or eliminating padding of the uplink communication.

Abstract: Methods, systems, and devices for wireless communications are described. To save energy at the network, synchronization signal blocks (SSBs) may be transmitted in an on-demand manner. For example, the network may transmit an SSB in response to a request for an SSB or an uplink wake-up signal (WUS) from a user equipment (UE). SSBs may be mapped to corresponding random access channel occasions (ROs) via control signaling such as radio resource control or system information. For example, the described techniques provide for rules and/or signaling that may indicate whether a network entity should monitor for, and thus whether a UE may transmit, in ROs corresponding to on-demand SSBs. In some examples, a UE may transmit a request for an on-demand SSB, receive an SSB based on the request, and selectively transmit a message to the network entity in an RO corresponding to the SSB based on reception of the SSB.

Numerous other aspects are described.

In one aspect, a wireless device segments each packet data convergence protocol (PDCP) packet in a plurality of PDCP packets into a set of OC symbols, where the plurality of PDCP packets corresponds to a packet data unit (PDU) set. The wireless device assembles multiple sets of OC symbols into an OC block. The wireless device applies an FEC encoding to the OC block. The wireless device outputs the OC block based on the FEC encoding. In some examples, the wireless device also adds an OC header to the OC block, where the OC header includes a symbol size, a set of source symbols, and/or a symbol index associated with the FEC encoding.

Some aspects more specifically relate to the utilization of beam-specific RACH parameters, such as synchronization signal block (SSB) reference signal received power (RSRP) thresholds, two-step RACH parameters, two-step RACH thresholds, physical uplink shared channel (PUSCH) RSRP thresholds, supplementary uplink (SUL) RSRP thresholds, and channel state information reference signal (CSI-RS) RSRP thresholds, to optimize RACH processes. In some examples, a UE obtains a beam-specific configuration including one or more of these beam-specific RACH parameters and a downlink reference signal from a network entity, and sends to the network entity a RACH message associated with the downlink reference signal based on the parameters.

Abstract: Methods, systems, and devices for wireless communications are described. For example, the described techniques enable user equipment (UEs) to perform feedback reporting. A first UE may communicate an indication that it is in a UE group associated with uplink feedback resource sharing among UEs in the UE group. The first UE may then receive one or more messages indicating sets of uplink feedback resources associated with the first UE and one or more other UEs in the UE group, the uplink feedback resources being configured for uplink feedback resources sharing. The UEs within the UE group may support shared feedback resources so that a UE may access and utilize any quantity of feedback resources associated with any UE that belongs to the same cooperative group. The first UE may select a resource from the sets of uplink feedback resources and may communicate uplink feedback based on the selection.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives a set of configuration parameters related to a hybrid automatic repeat request (HARQ) acknowledgement (ACK) codebook from a network entity, and identifies an operating state for each component carrier (CC) of multiple CCs associated with the UE based on the set of configuration parameters. The UE further allocates one or more entries of the HARQ ACK codebook based on the operating state for each CC of the multiple CCs, and transmits the HARQ ACK feedback associated with the one or more entries of the HARQ ACK codebook to the network entity.
