Abstract:
1. A method of frequency spectrum usage for communications in a wireless communication system, comprising: configuring, at a radio network subsystem, at least a first and second downlink carrier to have a total occupied bandwidth that is constrained within an allocated downlink frequency spectrum, the first downlink carrier having a first downlink carrier center frequency and the second downlink carrier having a second downlink carrier center frequency; transmitting, from the radio network subsystem to a user equipment (UE), at least a first and second downlink carrier center frequency indicator, wherein the first downlink carrier center frequency indicator identifies the first downlink carrier center frequency of the first downlink carrier, and wherein second downlink carrier center frequency indicator identifies the second downlink carrier center frequency of the second downlink carrier; and transmitting, from the radio network subsystem to the UE, at least one uplink carrier center frequency indicator that identifies at least one uplink carrier center frequency of at least one uplink carrier to be transmitted by the UE to the radio network subsystem within an allocated uplink frequency spectrum, wherein the at least one uplink carrier is configured by the radio network subsystem to have an independent, variable center frequency offset relative to the at least first and second downlink carriers.
