Abstract
A method, wireless transmit/receive unit (WTRU), and a wireless network node configured for wireless communications comprising receiving, by the WTRU, configuration information for a primary cell and one or more non-primary cells, receiving, by the WTRU, a message on the primary cell, the received message including indication of at least one of the one or more non-primary cells from which the WTRU is to receive a downlink shared channel transmission, and in response to the received message, receiving and processing, by the WTRU, the downlink shared channel transmission from the indicated at least one of the one or more non-primary cells.
Claims17
A wireless transmit/receive unit (WTRU) comprising:
- a transceiver;
- and
- a processor;
- and
- wherein the transceiver and the processor are configured to cause the WTRU to, while a primary cell is associated with a wireless network node and one or more non-primary cells are associated with the wireless network node:
- receive configuration information for the primary cell and the one or more non-primary cells;
- receive a message on the primary cell, the received message including an indication of at least one of the one or more non-primary cells from which the WTRU is to receive a downlink shared channel transmission;
- and
- in response to the received message, receive and process the downlink shared channel transmission from the indicated at least one of the one or more non-primary cells.
A method comprising:
- receiving, by a wireless transmit/receive unit (WTRU), configuration information for a primary cell and one or more non-primary cells, wherein the primary cell is associated with a wireless network node and the one or more non-primary cells are associated with the wireless network node;
- receiving, by the WTRU, a message on the primary cell, the received message including indication of at least one of the one or more non-primary cells from which the WTRU is to receive a downlink shared channel transmission;
- and
- in response to the received message, receiving and processing, by the WTRU, the downlink shared channel transmission from the indicated at least one of the one or more non-primary cells.
A wireless network node comprising:
- a transceiver;
- and
- a processor;
- and
- wherein the transceiver and the processor are configured to cause the wireless network node to, while a primary cell is associated with the wireless network node and one or more non-primary cells are associated with the wireless network node:
- transmit, to a wireless transmit/receive unit (WTRU), configuration information for the primary cell and the one or more non-primary cells;
- and
- transmit, to the WTRU, a message on the primary cell, the transmitted message including an indication of at least one of the one or more non-primary cells that a downlink shared channel transmission is scheduled.
