发明名称 Methods and apparatus for flexible use of frequency bands
摘要 Methods and systems are disclosed for communicating in a wireless communications system utilizing a plurality of frequency bands for downlink (DL) transmission and a plurality of frequency bands for uplink (UL) transmission. In an embodiment, a mobile device receives a DL signal via a DL frequency band. The DL signal contains DL-UL frequency-band association information. The DL signal is decoded to obtain the DL-UL frequency-band association information which is used to determine a UL frequency band for UL transmission. The mobile device configures its radio-frequency (RF) circuitry to operate in the UL frequency band for UL transmission.

主权项 1. A method for communicating by a mobile device served by a base station in a wireless communication system employing a plurality of radio frames, wherein the radio frames comprise a plurality of subframes, the subframes comprising a plurality of time slots, the time slots comprising multiple orthogonal frequency division multiplex (OFDM) symbols, the mobile device having a plurality of radio-frequency (RF) circuits, the method comprising: receiving, in a first duplexing mode, control information from the serving base station over a first RF band, the control information indicative of a second RF band for receiving signals by the mobile device in a second duplexing mode; and controlling the plurality of RF circuits to concurrently receive signals in a first radio frame in the first duplexing mode over the first RF band and in a second radio frame in the second duplexing mode over the second RF band; wherein at least one of the first RF band and the second RF band is allowed to be used by systems operating with different multiple access technologies; wherein the first radio frame and the second radio frame have a same frame length and are aligned with each other in time; and wherein the first duplexing mode operates in frequency and the second duplexing mode operates in time, or the first duplexing mode operates in time and the second duplexing mode operates in frequency.
