Abstract
Certain aspects of the disclosure provide for the protection of broadcast signals in heterogeneous networks. As described herein, a first set of resources used for downlink transmission in a first cell may overlap with a second set of resources used for broadcast signals in a second cell. The broadcast signals may be protected by allocating a third set of resources for the downlink transmission in the first cell, wherein the third set of resources is based, at least in part, on the overlapping set of resources.
Claims46
A method for wireless communications in wireless communications network, comprising:
- determining a first set of resources for downlink transmission to a first user equipment (UE) in a first cell;
- determining a second set of resources for use in transmitting broadcast signals to a second UE in a second cell, wherein the first set of resources and the second set of resources comprise an overlapping set of resources that at least partially overlap in time and frequency;
- and
- allocating a third set of resources for the downlink transmission in the first cell, wherein the third set of resources is allocated to mitigate interference by the downlink transmission in the first cell to transmissions in the second cell using the second set of resources and the third set of resources is allocated based, at least in part, on the overlapping set of resources.
An apparatus for wireless communications in wireless communications network, comprising:
- means for determining a first set of resources for downlink transmission to a first user equipment (UE) in a first cell;
- means for determining a second set of resources for use in transmitting broadcast signals to a second UE in a second cell, wherein the first set of resources and the second set of resources comprise an overlapping set of resources that at least partially overlap in time and frequency;
- and
- means for allocating a third set of resources for the downlink transmission in the first cell, wherein the third set of resources is allocated to mitigate interference by the downlink transmission in the first cell to transmissions in the second cell using the second set of resources and the third set of resources is allocated based, at least in part, on the overlapping set of resources.
An apparatus for wireless communications in wireless communications network, comprising:
- at least one processor configured to:
- determine a first set of resources for downlink transmission to a first user equipment (UE) in a first cell,
- determine a second set of resources for use in transmitting broadcast signals to a second UE in a second cell, wherein the first set of resources and the second set of resources comprise an overlapping set of resources that at least partially overlap in time and frequency, and
- allocate a third set of resources for the downlink transmission in the first cell, wherein the third set of resources is allocated to mitigate interference by the downlink transmission in the first cell to transmissions in the second cell using the second set of resources and the third set of resources is allocated based, at least in part, on the overlapping set of resources;
- and
- a memory coupled with the at least one processor.
A computer-program product for wireless communications comprising a non-transitory computer-readable storage medium having instructions stored thereon, the instructions executable by a processor for:
- determining a first set of resources for downlink transmission to a first user equipment (UE) in a first cell;
- determining a second set of resources for use in transmitting broadcast signals to a second UE in a second cell, wherein the first set of resources and the second set of resources comprise an overlapping set of resources that at least partially overlap in time and frequency;
- and
- allocating a third set of resources for the downlink transmission in the first cell, wherein the third set of resources is allocated to mitigate interference by the downlink transmission in the first cell to transmissions in the second cell using the second set of resources and the third set of resources is allocated based, at least in part, on the overlapping set of resources.
