    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.

    Abstract: Methods and systems are disclosed to configure different paging occasions for enhanced UEs that support, and for legacy UEs that do not support, the enhanced feature of the paging early indication (PEI) in paging procedure for 5G/LTE networks. Different paging occasions for the enhanced and legacy UEs may be configured by providing separate paging occasion parameters for the enhanced and legacy UEs. The network may use the separate paging parameters to design the PEI to save signaling overhead. The network may reuse paging format for the paging PDCCH to serve as the PEI that is transmitted in advance of the paging occasions for the enhanced UEs, or may keep legacy paging PDCCH at its current locations to serve as the PEI for the enhanced UEs. A scheduling offset may be configured to separate in time the paging PDCCH serving as the PEI and the paging PDSCH containing the paging message.
