Abstract: Embodiments of an integrated access and backhaul (IAB) donor, IAB node, and methods of communication are generally described herein. An IAB network may comprise a plurality of IAB nodes to operate as relays between the IAB donor and one or more User Equipment (UE). The IAB donor may, for each of the IAB nodes, allocate a plurality of subframes to the IAB node. Each allocated subframe may have a subframe type that is one of: a downlink subframe, an uplink subframe, a flexible subframe or a not available subframe. The IAB donor may transmit, from a central unit (CU) of the IAB donor to a distributed unit (DU) an IAB node over an F1 interface, a resource coordination request message that indicates the subframe types of the plurality of subframes.

Abstract: Provided is a method for a user equipment (UE). The UE obtains a first control information from a network device. The first control information indicates at least one physical downlink control channel (PDCCH) monitoring period for the UE. The UE further monitors PDCCH based on the at least one PDCCH monitoring period.

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.

The apparatus includes a RF interface to receive and transmit downlink data for one or more UEs or UE bearers; and a processing circuitry coupled with the RF interface. The processing circuitry is to determine a downlink congestion occurs at the relay node; and generate a downlink congestion indication to identify a UE or a UE bearer or a backhaul RLC channel affected by the downlink congestion. The RF interface is to transmit the downlink congestion indication to the donor node. In addition to the downlink congestion handling, the relay node can also be to handle uplink congestion in a similar way.

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.

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.

For instance, a data counter for two or more of a plurality of user equipment (UE) bearers handled by an IAB node can be configured. Data corresponding to the two or more UE bearers of the plurality of UE bearers can be received. A first UE bearer can be selected. The first UE bearer is the UE bearer having the lowest data counter value of the two or more UE bearers. Data corresponding to the first UE bearer can be transferred to a mobile terminal (MT) in the IAB node. The data counter for the first UE bearer can be increased by a total size of the transferred data.

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.

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.
