Base station code processing assistance for a code division multiplex format
View Patent ↗A first base station transceiver wirelessly receives communications from a first user in a code division multiplexing format using a first code assigned to the first base station transceiver. A second base station transceiver wirelessly receives communications from a second user in the code division multiplexing format using a second code assigned to the second base station transceiver. The base station transceivers determine and transfer wireless communication performance measurements. A network control system selects the second base station transceiver to assist the first base station transceiver based on the communication performance measurements. In response, the second base station transceiver wirelessly receives communications from a third user in the code division multiplexing format using the first code assigned to the first base station transceiver.
