摘要： Methods and devices are provided to enable a cooperating group of user equipments (UEs) to receive a group-specific common-parameters configuration (CPC) message over a first spectrum band and access a second spectrum band synchronously for device-to-device (D2D) sidelink transmission within the group. In an embodiment, a UE operating in a cooperation mode in a cooperating group of UEs receives a group-specific common-parameters configuration (CPC) message from a transmit point (TP) over a first spectrum band, the group-specific CPC message comprising information to configure cooperating UEs in the group for synchronous clear channel assessment (CCA) and aligned sidelink transmission starting times in a second spectrum band. The UE performs a synchronous CCA in the second spectrum band in accordance with a common contention window generated based on the information in the group-specific CPC message.

摘要： Methods, devices and systems are disclosed to enable the use of unlicensed wireless channels by nodes and devices in a network, such as a mobile or cellular communications network, which primarily operates over licensed wireless channels. A selected channel, or selected channel and node pair for serving a user device are determined based on a combined metric of a signal quality level and a target time share parameter. The time share parameter represents the estimated data rate available for each potential channel, or channel and node pair, in light of the requirement to share the unlicensed wireless channel resources with other equipment. The signal quality level represents an estimated signal quality at the user device for each channel and node based on factors including residual interference from other communications signals transmitted over the unlicensed channels.

摘要： Methods and systems for managing access of a communication resource in a licensed assisted access (LAA) network. Each transmission point (TP) of a plurality of TPs provides a first set of information indicative of expected usage of a first communication resource by each TP. Information is transmitted to the TPs to cause each TP to align usage or reservation of the first communication resource with any other TP belonging to a first radio access cluster (RAC) to which the given TP belongs, the first RAC being one in a first set of one or more RACs, wherein each of the plurality of TPs belongs to a respective RAC in the first set of RACs and each RAC in the first set of RACs contains one or more TPs.

摘要： A user equipment (UE) receives a message that indicates a sidelink (SL) communication resource configuration to be used by the UE for communicating SL control information and SL data between the UE and another UE. The UE transmits SL control information according to the SL communication resource configuration, and transmits SL data according to the SL communication resource configuration. The SL control information and the SL data are transmitted by the UE without the UE receiving, in a downlink control information (DCI), a grant of communication resources.

摘要： Systems and methods are disclosed for establishing a device-to-device (D2D) group amongst a plurality of user equipments (UEs). In one embodiment a target UE transmits, using D2D communication, a request message inviting at least one other UE to be part of a D2D group with the target UE. A neighbour UE receives the request message and transmits a report message indicating that the neighbour UE will be part of the D2D group with the target UE. A base station receives the report message and transmits to the target UE and to the neighbour UE a confirmation message indicating that the neighbour UE is in the D2D group with the target UE.

摘要： The invention provides a self-adaptive downlink power control scheme for OFDMA-based wireless cellular networks suitable for noise-limited environments. Downlink power levels are assigned in a distributed manner in the absence of any requirement for coordination or cooperation between cells. Distributed assignment allows for more optimal usage of the available transmit power at the base stations and more complete exploitation of the flexibility of frequency domain scheduling. In one embodiment, base stations in a cellular network service mobile user equipment within the respective base station coverage areas, and categorize the user equipment in a plurality of power levels according to certain criteria in accordance with such factors as channel experience and quality. A load-balancing self-adjustment mechanism allows automatic balancing of the load between different power levels.
