摘要： Methods and apparatuses are provided that include a mobile station modem (MSM) embedded in a repeater for enhancing repeater functionality. The MSM can determine a timing of a base station based on one or more signals received therefrom. Using the timing, the repeater can align timing to that of the base station, determine cyclic prefix of the received signals, cancel echo from received signals, switch between receiving uplink and downlink signals, transmit PRSs according to the timing, and/or the like.

摘要： Techniques for supporting communication for different user equipments (UEs) on different system bandwidths are described. In one design, a base station transmits first control information to support communication for at least one first UE on a first system bandwidth and transmits second control information to support communication for at least one second UE on a second system bandwidth, which overlaps the first system bandwidth. The base station transmits data to the first and second UEs on the first and second system bandwidths, respectively. In one design, the base station receives third control information from the first UE(s) and fourth control information from the second UE(s) on a third system bandwidth. The base station receives data from the first UE(s) on the third system bandwidth and receives data from the second UE(s) on a fourth system bandwidth, which overlaps the third system bandwidth.

摘要： Systems, methods and apparatuses are provided that facilitate selecting resources, such as time slots, subframes, etc., for performing bandwidth switching related to activating and/or deactivating one or more carriers. A data portion of one or more subframes can be selected for performing bandwidth switching. In addition, a device can determine whether one or more downlink grants are received in the one or more subframes, and can avoid selecting such subframes. The device can alternatively perform the bandwidth switching and request retransmission of the data portion. Additionally or alternatively, the device can determine a type of the one or more subframes and/or signals transmitted in the one or more subframes to determine whether to perform bandwidth switching in the subframes. The bandwidth switching can include changing a sampling rate, reconfiguring frequency filters, modifying a local oscillator, etc.
