Abstract
Notifying served user equipments (UEs) of the presence or absence of cell-specific reference signal (CRS) symbols transmitted by neighboring base stations in the physical downlink shared channel (PDSCH) region of a subframe can be achieved through various of signaling techniques. The served UE may be notified by communicating a one or multi-bit indicator in a physical layer signaling channel of the serving cell, such as the physical downlink control channel (PDCCH) of the subframe. Alternatively, the served UE may be notified through higher layer signaling.
Claims18
A method for operating a user equipment (UE), the method comprising:
- receiving, by the UE, at least one indicator from a first network controller, the at least one indicator specifying at least one parameter associated with cell-specific reference signal (CRS) symbols transmitted by a second network controller;
- and
- receiving, by the UE, a physical downlink shared channel (PDSCH) from the first network controller, the UE assuming that resource elements corresponding to the CRS symbols transmitting by the second network controller are not available for carrying the PDSCH received from the first network controller.
A user equipment (UE) comprising:
- a processor;
- and
- a computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
- receive at least one indicator from a first network controller, the at least one indicator specifying at least one parameter associated with cell-specific reference signal (CRS) symbols transmitted by a second network controller;
- and
- receive a physical downlink shared channel (PDSCH) from the first network controller, the UE assuming that resource elements corresponding to the CRS symbols transmitting by the second network controller are not available for carrying the PDSCH received from the first network controller.
