Abstract
Methods and apparatus for supporting coexistence between two different radio access technologies (RATs), such as the Long Term Evolution (LTE) standard and one of the IEEE 802.16 standards, are provided. To accomplish this coexistence, a multi-mode base station (BS) may replace transmission gaps in a frame of a first RAT with subframes or symbols of the second RAT and transmit the resulting dual-RAT frame. In this manner, a single BS may support and communicate according to two different RATs simultaneously.
Claims48
A method of wireless communications, comprising:
- determining one or more blank subframe structures in a frame of a first radio access technology (RAT);
- generating one or more second subframe structures of a second RAT to replicate the timing of the blank subframe structures;
- and
- transmitting the frame of the first RAT with the second subframe structures of the second RAT replacing the blank subframe structures of the first RAT.
A computer-program product for wireless communications comprising a computer-readable medium having instructions stored thereon, the instructions being executable by one or more processors and the instructions comprising:
- instructions for determining one or more blank subframe structures in a frame of a first radio access technology (RAT);
- instructions for generating one or more second subframe structures of a second RAT to replicate the timing of the blank subframe structures;
- and
- instructions for transmitting the frame of the first RAT with the second subframe structures of the second RAT replacing the blank subframe structures of the first RAT.
An apparatus for wireless communications, comprising:
- means for determining one or more blank subframe structures in a frame of a first radio access technology (RAT);
- means for generating one or more second subframe structures of a second RAT to replicate the timing of the blank subframe structures;
- and
- means for transmitting the frame of the first RAT with the second subframe structures of the second RAT replacing the blank subframe structures of the first RAT.
An apparatus for wireless communications, comprising:
- logic for determining one or more blank subframe structures in a frame of a first radio access technology (RAT);
- logic for generating one or more second subframe structures of a second RAT to replicate the timing of the blank subframe structures;
- and
- logic for transmitting the frame of the first RAT with the second subframe structures of the second RAT replacing the blank subframe structures of the first RAT.
