摘要： This disclosure describes systems, methods, and devices related to deterministic backoffs and collision avoidance. A device may identify a first transmission received from a first device, wherein the first transmission is over a shared access medium. The device may identify a second transmission received from the first device, wherein the second transmission is over the shared access medium. The device may determine an available transmission slot between the first transmission and the second transmission. The device may transmit, during the available transmission slot, a third transmission.

摘要： A method can be performed by a first node for determining a parameter of physical (PHY) layer circuitry of a second node. The method can include implementing a cascaded hierarchy of techniques to determine, based on an electrical signal from a second node, a parameter of the PHY layer circuitry of the second node, and causing an antenna of the first node to transmit an electromagnetic wave consistent with the determined parameter.

摘要： Systems and methods provide resource allocation signaling for low cost machine type communication (LC-MTC) devices with the elimination of the physical downlink control channel (PDCCH) in long term evolution (LTE) communication systems. Disclosed systems and methods provide alternative light-weight, efficient control signaling for resource allocation of LC-MTC devices.

摘要： Methods, apparatus circuitry, and storage media are described for mobile-terminated packet transmissions. In one embodiment, an apparatus of a control plane device configured to operate within an evolved packet network core identifies a first service flow event trigger associated with a first packet data unit (PDU) session and processes a path reselection for a first PDU session in response to the first service flow event trigger, wherein the path reselection determines a new gateway for the first PDU session resulting from the path reselection. Transmission of a change notification to an application server controller associated with the first PDU session is initiated in response to the path reselection. Transmission of a routing update to the new gateway in response to the path reselection is also initiated. In various embodiments, the trigger may be a mobility event, a load balancing event, or operations in association with an application server controller.

摘要： In wireless communication networks in which pairs of STAs establish direct point-to-point links with each other, RTS-CTS training may be used to make sure that they don't interfere with other such pairs that communicate simultaneously during contention based access periods (CBAP). In some embodiments, two different types of CBAP are described for this. The PCP/AP may separately designate each type of CBAP for those devices using RTS-CTS training and those not using such training. In other embodiments, specific formats and fields are presented for communications involving these features.

摘要： Technology for a user equipment (UE) operable to receive system information change notifications from an eNodeB is disclosed. The UE can receive one or more system information (SI) change notifications that indicate a change has occurred in one or more system information blocks (SIBs). The UE can receive a SIB1 that is associated with a value tag, and the SIB1 can include a bit-map that indicates which of the one or more SIBs include a change. The UE can compare the value tag associated with the SIB1 with a value tag stored at the UE. The UE can obtain scheduling information for the one or more SIBs that include a change according to the bitmap when the value tag associated with the SIB1 does not equal to the value tag stored at the UE. The UE can retrieve the SIBs that include a change using the scheduling information.

摘要： Embodiments of an Evolved Node-B (eNB) to support Mission-Critical Machine Type Communication (MC-MTC) User Equipments (UEs) are disclosed herein. During a transmission notification (TN) monitoring period, the eNB may monitor for TN signals from MC-MTC UEs. When a presence of TN signals is detected, the eNB may refrain from allocation of dedicated MC-MTC traffic resources to other UEs for transmission during a traffic period. In response to a detection of an absence of TN signals from the first group of MC-MTC UEs during the TN monitoring period, the eNB may allocate the dedicated MC-MTC traffic resources to the other UEs for transmission during the traffic period. Starting times of the traffic period and the TN monitoring period may be spaced apart by a predetermined time difference. In some embodiments, the predetermined time difference for MC-MTC UEs may be not greater than 10 milliseconds.

摘要： Embodiments of Evolved Node-B (eNBs), user equipment (UE) and methods for licensed shared access (LSA) handover are generally described herein. An eNB includes hardware processing circuitry to receive a command to release spectrum resources in a LSA band over which the eNB serves an LSA cell; to determine whether user equipment (UEs) served by the eNB are permitted to skip a random access process (RAP) to be handed over to a target cell operating on a band separate from the LSA band; and to transmit a message to a UE served by the eNB instructing the UE that the UE is to be handed over to the target cell, the message including one or more indicators based on the determination. Other apparatuses, systems and methods are also disclosed.

摘要： Embodiments of an Evolved Node-B (eNB) to support Carrier Aggregation (CA) of a licensed frequency band and an unlicensed frequency band are disclosed herein. The eNB may transmit traffic packets on an unlicensed channel in the unlicensed frequency band to one or more User Equipments (UEs) assigned to the unlicensed channel. The eNB may receive, on the licensed frequency band, interference indicators for the unlicensed channel from at least a portion of the UEs assigned to the unlicensed channel. In addition, the eNB may transmit, on the licensed frequency band, a multicast vacate channel control message for the unlicensed channel. The message may be for reception at one or more of the UEs assigned to the unlicensed channel.
