Patent ID: 10952031

Abstract:
Methods and devices are provided to enable a cluster of user equipments (UEs) to receive a multicast signal over a first spectrum band and access a second spectrum band as a single virtual entity for device-to-device (D2D) mutual broadcast within the cluster. In an embodiment, a first UE in a cluster receives a multicast signal from a wireless network over the first spectrum band, the multicast signal including downlink information targeted to a second UE in the cluster. The first UE performs in a contention procedure for a transmission opportunity (TXOP) in the second spectrum band in accordance with group listen-before-talk (LBT) parameters configured for the cluster. If the contention procedure has acquired a TXOP in the second spectrum band for the cluster, the first UE sends at least a portion of the downlink information to the second UE over the second spectrum band during the TXOP.
