Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving control signaling that configures the UE with a retransmission request time duration for requesting packet retransmission relative to when a packet in a sequence of packets is determined to be unsuccessfully received, monitoring for one or more transmissions including at least a subset of packets in the sequence of packets, and transmitting, prior to expiration of the retransmission request time duration, a first retransmission request to request retransmission of at least one packet in the sequence of packets based on a first retransmission trigger being satisfied.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, such as a user equipment may identify a size capability for a buffer associated with a protocol layer of the UE. The buffer may be a layer two buffer and the protocol layer may be a layer two protocol layer. The UE may transmit, to a base station serving the UE, an indication of the identified size capability for the buffer. In some cases, the UE may transmit the indication of the identified size capability in a UE capability report in radio resource control signaling. The UE may then communicate, with the base station 105, data that is scheduled based on the transmitted indication.

Abstract: Wireless communications systems and methods related to buffer/memory management for multi-connectivity in a wireless communication network are provided. A wireless communication device transmits a first portion of a plurality of data packets using a first radio access technology (RAT). The wireless communication device transmits a second portion of the plurality of data packets using a second RAT different from the first RAT. The wireless communication device stores at least some of the plurality of data packets in a memory pending an acknowledgement (ACK) indication associated with at least a first data packet of the plurality of data packets. The wireless communication device determines a transmission configuration for at least the first data packet and a second data packet based on whether a threshold occupancy of the memory is satisfied. Other aspects and features are also claimed and described.

Abstract: A backup manager for providing backup services includes storage and a backup orchestrator. The persistent storage stores prediction models. The backup orchestrator obtains a computing resource availability for a client; generates a prediction model of the prediction models using the computing resource availability for the client; predicts, using the prediction model and live data, a future computing resource availability for the client; and initiates generation of a backup for the client at an unscheduled time that is based, at least in part, on the future computing resource availability.

Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive, at a first operational layer of the receiving device, one or more protocol data units (PDUs) within a set of PDUs. The receiving device may identify, at a second operational layer of the receiving device, a sequence gap associated with a missing PDU from the set of PDUs, the first operational layer being a lower operational layer of the receiving device than the second operational layer. The receiving device may determine, at the second operational layer, that a triggering condition associated with the missing PDU has occurred. The receiving device may provide, by the second operational layer and based at least in part on the triggering condition occurring, an indication to update a reception buffer of the first operational layer to a last received protocol data unit of the set of PDUs.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine that a number of access stratum (AS) operations or communications have failed while attempting to communicate with a cell. Based on the AS failures, the UE may deprioritize the cell. For example, based on the deprioritization, the UE may bar certain cells from selection or reselection procedures. The UE may thus attempt to select or reselect a different cell even if the cell is ranked lower based on a selection criteria or reselection criteria. In some cases, UEs may store and share historical AS failure information that may also be used to determine when to deprioritize a cell. In some cases, a group of cells may be deprioritized (e.g., a group based on frequency, network, or tracking area).

Abstract: Systems and/or devices for controlling access to a content distribution system and/or controlling content distributed via the system are provided. In some examples, a system may include a content distribution computing platform that may be configured to receive credentials from a user, generate a user interface and transmit the user interface to the user. Via the generated user interface, a user may request to distribute content to one or more computing destinations, such as one or more folders, servers, or other computing destinations or devices. Upon receiving the request, the system may determine whether the user is authorized to distribute content, whether a type of content associated with the content is authorized for distribution and/or whether attributes of the content are permitted for distribution. If so, the content may be distributed. If not, a notification may be transmitted to the user (e.g., to a computing device of the user).

Abstract: Certain aspects of the present methods for handling user equipment (UE) pages in a Radio Resource Control (RRC) connected mode of the UE. Aspects of the present disclosure may effectively scale a point (in time) until which the UE shall handle pages in the RRC connected mode, and after which the UE detects out-of-sync with the NW, which may allow the UE to performs procedures that may help enhance user experience.

Abstract: Aspects of the present disclosure provide apparatus and techniques for determining one or more operating conditions related to a UE and transmitting a power preference indication (PPI) to an cNB based, at least in part, on the determination. The one or more operating conditions may be related to at least one of a throughput, battery configuration, application data history, or temperature of the UE. In response to the determination, the UE may transmit one of a PPI that is set to or indicates normal power mode or a PPI that is set to low power mode, for example. Additionally, the UE may decide whether or not to delay sending a scheduling request (SR) to the eNB based, at least in part, on the determination.

Abstract: Methods, systems, and devices are described for reducing congestion in a wireless communications system. A second connection failure is detected, and a difference between a timestamp of the second connection failure and a timestamp of a first connection failure is calculated. Upon determining that the difference satisfies a first time threshold, information relating to one or more previous connection failures is cleared. A time period is identified. A number of connection failures from a cell that occur during the time period is identified. A determination is made as to whether the number of connection failures satisfies a threshold. Upon determining that the number of connection failures satisfies the threshold, a future connection request may be withheld for a time period.

The UE prioritizes network reestablishment on the one or more frequencies that carry the MBMS service the UE is interested in receiving upon determining the UE encountered the one of the RLF or the OOS.
