    Abstract: Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to determine that the UE is in an Inactive Radio Resource Control (RRC) state. The second circuitry may be operable to process a first transmission received by the UE while the UE is in the Inactive RRC state, the first transmission carrying a set of one or more Access Control (AC) parameters. The third circuitry may be operable to regulate the sending of a second transmission, in accordance with the set of one or more AC parameters, while the UE is in the Inactive RRC state.

    Abstract: Technology for a user equipment (UE), operable to generate an enhanced buffer status report (eBSR) is disclosed. The UE can identify packets for uplink transmission. The UE can filter the packets for uplink transmission, to identify a number of small packets pending for transmission and a number of larger packets, relative to the small packets, that are pending for transmission in the uplink transmission. The UE can encode the eBSR for transmission to a next generation node B (gNB), wherein the eBSR includes information identifying the numbePr of small packets pending for transmission. The UE can have a memory interface configured to send to a memory the number of small packets pending for transmission.

    Abstract: Downlink spectral capacity of an eMBMS cell to be maximized for the eMBMS users. In one embodiment, supplementary eMBMS cells may be used together with a primary cell, in which the supplementary eMBMS cells broadcast only eMBMS content and the primary cell is used for uplink and downlink signaling. The primary cell may perform signaling for the corresponding supplementary cells. In this manner, signaling relating to configuring of the eMBMS cells may be offloaded to the non-eMBMS primary cell and eMBMS specific services can be fully utilized from the eMBMS cells. In a second embodiment, an eMBMS cell may be a standalone eMBMS cell that is not associated with a primary cell. In this embodiment, self-contained eMBMS signaling is defined. Additionally, eMBMS data may be broadcast in specified MBSN subframes. In this manner, a device, such as an eMBMS-only device, can independently receive eMBMS services.

    Abstract: Adaptive paging techniques for EC-capable devices are described. In one embodiment, for example, an apparatus may comprise at least one memory and logic for an evolved node B (eNB), at least a portion of the logic comprised in hardware coupled to the at least one memory, the logic to receive an S1 paging message comprising a user equipment (UE) identifier (ID) associated with a UE and an extended coverage (EC) capability indicator indicating that the UE is EC-capable and page the UE using an EC paging sequence based on receipt of the S1 paging message, the EC paging sequence to comprise a series of transmissions of a radio resource control (RRC) paging message, the logic to truncate the EC paging sequence based on a determination that the UE has responded to RRC paging. Other embodiments are described and claimed.

    Abstract: Methods and apparatus adapted to address asymmetric conditions in a multi-antenna system. In one embodiment, the multi-antenna system comprises a wireless (e.g., 3G cellular) multiple-input, multiple-output (MIMO) system, and the methods and apparatus efficiently utilize transmitter and receiver resources based at least in part on a detected asymmetric condition. If an asymmetric condition is detected by the transmitter on any given data stream, the transmitter can decide to utilize only a subset of the available resources for that stream. Accordingly, the signal processing resources for that data stream are adapted to mirror the reduction in resources that are necessary for transmission. The transmitter signals the receiver that it will only be using a subset of the resources available, and the receiver adapts its operation according to the signaling data it receives. The multi-antenna system can therefore reduce power consumption as well as increasing spectral efficiency on the network.
