Abstract
Methods and apparatus for providing wireless communications using subframe partitioning are disclosed. Two or more base stations may be allocated subframes in a radio frame. All or part of the subframe allocation may be provided to the associated user equipment (UEs), which may use it to determine signal metrics during assigned subframes for an associated base station.
Claims55
A method for wireless signal transmission, the method comprising:
- storing, in a first base station, a subframe partition configuration, wherein the subframe partition configuration includes an interlace allocation of a first downlink (DL) resource that is configured as one of a semi-static resource or dynamic resource;
- and
- transmitting, from the first base station, a first signal according to the the first DL resource allocation,
- wherein the first DL resource is time-division orthogonal to a second DL resource allocated to a second base station;
- wherein a base station type of the first base station is one of a first power class macrocell base station, a second power class macrocell base station, a femtocell base station, or a picocell base station;
- and
- the base station type of the first base station is different from a base station type of the second base station.

A computer program product comprising a non-transitory computer-readable medium including code for causing a computer to:
- store, in a first base station, a subframe partition configuration, wherein the subframe partition configuration includes an interlace allocation of a first downlink (DL) resource that is configured as one of a semi-static resource or dynamic resource;
- and
- send, from the first base station, a first signal according to the first DL resource allocation,
- wherein the first DL resource is time-division orthogonal to a second DL resource allocated to a second base station;
