Abstract: This application relates to systems and methods for recovering data in multimedia file segments. A communication device may receive a multimedia file segment that includes damaged data. The communication device may replace the damaged data with dummy data to reconstruct the multimedia file segment. The communication device may then play the reconstructed multimedia file segment. Thus, by replacing the damaged data with dummy data, the communication device may play a multimedia file segment even when part of the segment may be damaged.

Abstract: Techniques are provided for reducing delay during streaming transmissions. For example, a method may include receiving a stream of data segments. The method may include establishing a first group of segments based on the data segments, and generating a first table of information. The method may include transmitting the first table and the first group of segments, and establishing a second group of segments based on the data segments, the second group of segments including a partial overlap of data segments included in the first group of segments. The method may include generating a second table of information, and transmitting the second table and a collection of segments that includes data segments from the second group that were not part of the first group.

Abstract: Methods, systems, and devices for wireless communications are described that provide for receive chain selection at a user equipment (UE) with efficient switching between a reduced number of receive chains and an increased number of receive chains for downlink communications based on conditions at the UE. A UE may adaptively adjust the number of active receive chains based on downlink grant activity, channel conditions, network parameters, or any combinations thereof. An estimator block at the UE may determine to adjust the number of receive chains based on a number of downlink grants within one or more time periods. In some cases, grants for an amount of data that exceeds a threshold may be qualified in order to be counted at the estimation block. Further, a transient state may be provided where the UE may maintain a higher number of active receive chains until UE feedback is provided.

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: Aspects disclosed in the detailed description include power saving techniques in computing devices. In particular, as data is received by a modem processor in a computing device, the data is held until the expiration of a modem timer. The data is then passed to an application processor in the computing device over a peripheral component interconnect express (PCIe) interconnectivity bus. On receipt of the data from the modem processor, the application processor sends data held by the application processor to the modem processor over the PCIe interconnectivity bus. The application processor also has an uplink timer. If no data is received from the modem processor before expiration of the uplink timer, the application processor sends any collected data to the modem processor at expiration of the uplink timer. However, if data is received from the modem processor, the uplink timer is reset.

Abstract: A user equipment (UE) may simulate transmissions received from a BS to perform on-device testing of the UE. For example, the UE may be configured to loopback uplink data from the UL data path and input the uplink data as simulated downlink data for processing in the DL data path. The uplink data may include data related to a video call or network diagnostics. The user application data generated by the application and proceeding through the UL data path may be used to validate the DL data path. Downlink control information (DCI) may be determined by the UE and provided to the DL data path to accompany the uplink data. The DCI may include simulated uplink grants and/or simulated downlink scheduling assignments. The simulated downlink scheduling assignments may be determined based on availability of the uplink data in the UE's memory.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for managing scheduling requests (SRs) in a user equipment (UE) that supports a split data radio bearer (DRB). In some aspects, the UE may trigger a first SR for a first communication link and a second SR for a second communication link in response to determining that a first amount of data in the UE data buffer is greater than a first threshold. The UE may transmit the first SR to a first base station (BS) via the first communication link. Prior to transmission of the second SR, the UE may determine whether a second amount of data in the UE data buffer is less than a second threshold. The UE may cancel the second SR in response to the second amount of data in the UE data buffer being less than the second threshold.

Abstract: Aspects of the present disclosure describe transmitting data in wireless communications. A set of packets for transmission in a defined sequence can be received where the set of packets includes two or more packets. It can be detected that a packet, of the set of packets, is a prioritized packet type. The packet can be prioritized for transmission ahead of its order in the defined sequence based on the detection of the prioritized packet type. The packet can be transmitted ahead of its order in the defined sequence to an access point.

Abstract: Disclosed are techniques for transmitting bundles of silence indicator (SID) frames during a voice call among a plurality of access terminals. In an aspect, a source access terminal detects a transition to a silence state, generates, in response to detection of the transition, at least a first bundle of SID frames, wherein each SID frame of the at least the first bundle of SID frames includes data representing comfort noise to be played at one or more target access terminals of the plurality of access terminals during the silence state, and transmits the at least the first bundle of SID frames to a base station serving the source access terminal. In an aspect, the base station receives the at least the first bundle of SID frames, and periodically forwards SID frames of the at least the first bundle of SID frames to the one or more target access terminals.
