Apparatus and methods of frequency spectrum usage in a wireless communication system

摘要

Techniques of frequency spectrum usage in a wireless communication system include configuring two or more downlink carriers, each having a downlink carrier center frequency, to have a total occupied bandwidth that is constrained within an allocated downlink frequency spectrum. Further, the techniques include transmitting, to a user equipment (UE), two or more downlink carrier center frequency indicators that each identify a downlink carrier center frequency of each of the two or more downlink carriers. Also, the present techniques may include transmitting, to the UE, at least one uplink carrier center frequency indicator that at least relatively identifies at least one uplink carrier center frequency of at least one uplink carrier that is configured to have an independent, variable offset relative to one or more of the more than two downlink carriers. As such, these aspects allow new ways of squeezing carriers into the downlink while not impacting UE transmitter complexity.

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.
