Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A user equipment device (UE) may transmit to abase station (BS) a first buffer status report (BSR) indicating an amount of uplink data buffered by the UE for transmission to the BS, and may subsequently transmit to the BS a first BSR update message indicating that an additional amount of uplink data has been buffered by the UE subsequent to transmission of the first BSR. The first BSR update message may be transmitted prior to expiration of a timer authorizing transmission of a second BSR following the first BSR. The UE may receive from the BS an uplink grant allocating resources for transmission of at least a portion of the uplink data buffered by the UE. The uplink grant may have a size based on the first BSR and the first BSR update message.

Abstract: A device may obtain, through wireless signaling from a network, a time-domain wireless-resource allocation (TWRA) pattern allocated to the device by the network and corresponding to a future time interval (TTI) for which the device has not yet decoded corresponding control information. This enables the device to conduct wireless communications during the TTI using resources allocated according to the obtained TWRA pattern, without first having to decode control information to identify the TWRA pattern. The device may obtain the TWRA pattern by obtaining an indication from the network that the TWRA pattern remains associated with future wireless communications of the device until indicated otherwise by the network, and/or by transmitting to the network an indication of preferred parameters associated with the future wireless communications and the TWRA pattern, and/or by transmitting to the network a request to have the network change from a different TWRA pattern to the TWRA pattern.

Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A user equipment device (UE) may transmit to a base station a random access initiation message, having a characteristic that is configured to indicate to the base station a requested size of a subsequent uplink grant to be provided by the base station for transmission of uplink data by the UE. For example, the characteristic may include a predetermined preamble included in the random access initiation message, such that a requested grant size is indicated by which preamble the UE selects from a plurality of possible preambles. As another example, the characteristic may include which RACH occasion is selected by the UE to transmit the random access initiation message. In response, the base station may allocate resources for use by the UE based on the characteristic.

Abstract: A communications system may include a user equipment (UE) device that communicates with a network. The UE may gather first contextual information about usage of the UE device, may receive second contextual information about usage of the network, and may receive third contextual information about usage of additional UE devices. The UE may run an application that requests wireless data transfer. The UE may train a learning model based on the contextual information. The UE may make a network connectivity decision based on the contextual information, the learning model, and a data sensitivity of the application. Once the connectivity decision is made, signals may be conveyed to implement the decision. Performing the connectivity decision on the UE instead of the network may allow the UE and the network to take full advantage of contextual learning in different use cases to optimize performance of both the UE and the network.

Abstract: A user equipment (UE) passively determines the presence of a cellular network bottleneck in a downlink channel and may take appropriate actions to mitigate the bottleneck. The UE may analyze the transport block size (TBS) of slots of received downlink traffic and assign states the to various slots based on this analysis. Based on these assigned states, the UE may identify a burst of network traffic from network traffic received from the cellular network, and the UE may also determine the burst duration as well as a busy estimation. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the burst duration and the busy estimation.

Abstract: A processor determines that a UE operates in a DRX cycle including a DRX-on duration followed by a DRX-sleep duration. The processor configures a plurality of periodic uplink CG occasions within the DRX cycle. Each uplink CG occasion supports uplink transmission of a predefined size. The processor reads a data buffer to determine a size of accumulated data. At a given uplink CG occasion, the processor compares the size of accumulated data with an upper threshold data size and a lower threshold data size. Responsive to a first comparison result, the processor transmits the accumulated data over one or more uplink CG occasions starting from the given uplink CG occasion. Responsive to a second comparison result, the processor transmits a BSR at the given uplink CG occasion. Responsive to a third comparison result, the processor transmits neither the accumulated data nor the BSR at the given uplink CG occasion.

Abstract: A network may include user equipment (UE) devices and a base station that communicates using a control unit (CU) and a data unit (DU). A primary UE may duplicate the DU and a subset of control functions of the CU. When the DU on the primary UE is active, the base station and primary UE may effectuate a split or bearer duplication of the DU at the RLC/PDCP/MAC layer between the primary UE and the base station. Data may be concurrently routed data through the primary UE using inter-UE links and direct cellular telephone links to the base station. When the subset of the control functions of the CU are active on the primary UE, the device may perform RRC functions, MAC control functions, RLC control functions, or other control functions to generate information for use by the base station in updating communications.
