Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A base station (BS) may receive from a user equipment (UE) a first buffer status report (BSR) indicating an amount of uplink data buffered by the UE for transmission to the BS, and may subsequently receive 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 received prior to expiration of a timer authorizing transmission of a second BSR following the first BSR. In response, the BS may allocate resources for transmission to the UE, based on the first BSR and the first BSR update message. The BS may provide an uplink grant identifying the allocated resources.

Abstract: While in an inactive state, a user equipment (UE) device transmits a message to a base station. The message indicates the UE device's intent to perform transmission and/or reception of user data with the network during the inactive state. The message may include a portion of the user data and/or a buffer status report. The UE device receives a response message that induces a state transition in the UE device. Different state transitions (e.g., to idle, inactive, legacy inactive, connected) may be induced by different types of response message (e.g., release, release with suspend configuration, resume, setup). One particular type of response message causes the UE to stay in the inactive state and enables subsequent user data transmission/reception in the inactive state. The response message may implicitly (or explicitly) indicate that forwarding of the user data to a core network was successful.

Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A base station may receive from user equipment device (UE) 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.

The uplink grant may have a size based on the first BSR and the first BSR update message.

Abstract: Apparatuses, systems, and methods for PDCCH enhancements for group-based paging indications. A user equipment device may be configured to receive, from a network, an indication of a paging occasion via a PG-RNTI and/or via at least 6 bits of a DCI. A value of the PG-RNTI may be associated with the paging occasion as well as a set of UEs, including the UE. The UE may be configured to monitor the paging occasion based on the value of the PG-RNTI and receive, during the paging occasion, a paging indication via at least six bits of a DCI, where each bit of the at least six bits may indicate a paging indication for a particular set of UEs and the particular set of UEs may be a subset of the set of UEs. The UE may also be configured to, in response to determining that the UE has a paging message, decode a corresponding PDSCH.
