  • Publication number: 20240196379
    Abstract: A non-transitory computer-readable storage medium stores instructions for execution by one or more processors of user equipment (UE). The instructions cause the UE to encode a scheduling request (SR) for transmission to a base station during one of a plurality of SR occasions. The SR includes an indication based on a size of an uplink (UL) data packet. Control information received from the base station in response to the SR is decoded. The control information includes a scheduling grant based on the size of the UL data packet. The UL data packet is encoded for transmission using the scheduling grant. The UL data packet is encoded for transmission using the scheduling grant.

  • Publication number: 20240188073
    Abstract: An application may provide prebooking information for multiple packet streams to a baseband processor. The prebooking information may include some or all of a first packet stream and information describing one or more additional packet streams. The baseband processor may generate a buffer status report (BSR) corresponding to multiple packet streams to the extent that the data for the packet streams are to arrive at the baseband processor prior to the a preconfigured duration (e.g., the baseband processor receiving a dynamic grant (DG) from the base station). In this sense, application data may be prebooked, by the baseband processor and/or base station, before actually arriving at the baseband processor. These and many other examples and techniques described herein, including the use of dummy packets for a DG, managing DGs based on dummy packets, and more.

  • Patent number: 11985652
    Abstract: Systems and methods for enhancing the use of pre-emptive buffer status reports (pre-BSRs) in wireless communications systems implementing integrated access and backhaul (IAB) networks are disclosed herein. In some cases, an IAB node can re-classify the LCGs of one or more incoming data flows according to such pre-BSR usage. This may involve the use of and extended medium access control (MAC) control element (MAC CE) having more LCG bits than previously contemplated, having sub-LCG bits, or that includes further LCG classification information bits. Other embodiments use a priority index for LCGs in an extended pre-BSR MAC CE. The priority index may include one or more of a priority field, a prioritized bit rate (PBR), and/or a bucket size duration (BSD) that is reported to an IAB donor. Other embodiments leverage the provision of additional grants from an IAB node to a child IAB node to reduce unwanted pre-BSR effects.

  • Patent number: 11910470
    Abstract: An indication of a first energy detection threshold for a first clear channel assessment (CCA) can be received at a mobile device from a cell operating on an unlicensed carrier. The first energy detection threshold can be different than a second energy detection threshold for a second CCA at a network entity of the cell. A determination can be made as to whether the unlicensed carrier is occupied based upon the first CCA and the received first energy detection threshold. A data packet can be communicated between the mobile device and the cell when the unlicensed carrier is not otherwise occupied.

The base station can transmit an activation command on the first serving cell for receipt by a UE, the activation command being configured to activate the UE to receive transmissions from the base station on the second serving cell. The base station can transmit after determining that the unlicensed carrier frequency is free, a reserve transmission on the unlicensed carrier frequency at least until the base station begins transmission of the activation command on the first serving cell.

  • Publication number: 20240007955
    Abstract: Methods and systems to manage an environmental condition, such as power consumption and/or temperature, of an integrated circuit (IC) device by controlling a bandwidth of a packet-based communication interface of the IC device (e.g., a PCIe interface). Bandwidth may be controlled by controlling delay between packets or controlling delay of a handshake signal. Delay may be increased when the environmental condition reaches a first threshold. Delay may be reduced when the environmental condition falls to a second threshold. Bandwidth may be regulated with proportional-integral control provided by a firmware controller and/or hardware. Bandwidth may be separately controlled for upstream and downstream paths based on bandwidth utilization of the respective paths. Bandwidth control may utilize codes stored in selectable registers. The IC device may include a field programmable gate array (FPGA) and may be configured as an accelerator card.

  • Publication number: 20240008136
    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.
