Patent ID: 8891464

Claim:
A wireless Base Station (BS) system, operative to assign dynamically a plurality of radio transceiver chains among a varying number of wireless channels, comprising: a Base-Band (BB) subsystem comprising N digital ports, operative to synthesize N digital Base-Band (BB) signals associated with K wireless channels, wherein N is equal to at least 2, K is equal to at most N, and K is equal to at least 1; and N radio transceiver chains, each connects to one of the N digital ports of the BB subsystem via an Analog-Digital interface; wherein the system is configured to: set dynamically K according to a first criterion, wherein K is a number between 1 and N; assign dynamically the N radio transceiver chains among the K wireless channels according to a second criterion, such that each radio transceiver is assigned to only one of the wireless channels; synthesize, by the BB subsystem, the N digital BB signals associated with the K wireless channels; and input the N digital BB signals to the N radio transceiver chains via the corresponding N digital ports and the corresponding Analog-Digital interfaces, thereby transmitting the K wireless channels via the N radio transceiver chains.
