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.
