    摘要： A system and method for implementing call handover (HO) is disclosed. A user equipment (UE) may be configured to communicate with a wireless communication network. The UE is configured to transmit a measurement report to at least one of a serving cell and at least one cell of a coordinated multi-point (CoMP) cell set. The UE is configured to listen for an HO command from a serving cell. The HO command identifies a target cell. The UE is configured to detect a radio link failure between the UE and the serving cell, listen for an HO command from a first cell in the CoMP cell set for a first time duration, and, when an HO command is received from the first cell in the CoMP cell set within the first time duration, perform handover to the target cell identified in the HO command.

    摘要： A system and method for implementing call handover (HO) is disclosed. A user equipment (UE) is configured to communicate with a wireless communication network. The UE is configured to transmit a measurement report to at least one of a serving cell and at least one cell of a coordinated multi-point (CoMP) cell set. The UE is also configured to listen for control channel transmissions from at least one of the serving cell and a first cell in the CoMP cell set, receive a resource allocation from at least one of the serving cell and the first cell in the CoMP cell set, and receive an HO command jointly from the serving cell and the first cell in the CoMP cell set. The HO command identifies a target cell. The UE is also configured to perform handover to the target cell identified in the HO command.

    摘要： Supplemental node transmission assistance in a wireless network provides for transmissions between a wireless network and wireless user equipment in a first direction using a serving node of the wireless network while providing for transmissions between the wireless network and wireless user equipment in a second direction using a supplemental node of the wireless network. The supplemental node is selected based on providing better channel conditions between the network and the user equipment in the second direction than the serving node. The supplemental node thus provides transmission assistance for the serving node in order to provide the best available downlink and uplink communications between the user equipment and the network.
