Abstract
A method for communicating in an advanced long term evolution (LTE-A) network using common reference signal (CRS) resources associated with different interference levels due to resource partitioning is disclosed. Signals are received from an eNodeB indicating a subset of CRS resources for radio link monitoring (RLM) and/or reference signal received power (RSRP) measuring. The subset of CRS resources includes the CRS resources expected to have lower interference from the interfering eNodeBs. RLM and/or RSRP measurements are performed based on the indicated subset.
Claims8
A method for communicating in an advanced long term evolution (LTE-A) network using common reference signal (CRS) resources associated with different interference levels due to resource partitioning, comprising:
- receiving signals from an eNodeB indicating a subset of CRS resources for at least one of radio link monitoring (RLM), reference signal received power (RSRP) measuring, or a combination thereof, the indicated subset of CRS resources comprising CRS resources having protected subframes during which interfering eNodeBs are prohibited from transmitting data;
- and
- performing at least one of RLM, RSRP measuring, or a combination thereof based on the indicated subset of CRS resources.
An apparatus for wireless communication, comprising:
- means for receiving signals from an eNodeB indicating a subset of CRS resources for at least one of radio link monitoring (RLM), reference signal received power (RSRP) measuring, or a combination thereof, the indicated subset of CRS resources comprising CRS resources having protected subframes during which interfering eNodeBs are prohibited from transmitting data;
- and
- means for performing at least one of RLM, RSRP measuring, or a combination thereof based on the indicated subset of CRS resources.
A computer program product for wireless communication in a wireless network, comprising:
- a non-transitory computer-readable medium having program code recorded thereon, the program code comprising:
- program code to receive signals from an eNodeB indicating a subset of CRS resources for at least one of radio link monitoring (RLM), reference signal received power (RSRP) measuring, or a combination thereof, the indicated subset of CRS resources comprising CRS resources having protected subframes during which interfering eNodeBs are prohibited from transmitting data;
- and
- program code to perform at least one of RLM, RSRP measuring, or a combination thereof based on the indicated subset of CRS resources.
An apparatus for wireless communication, comprising:
- a memory;
- and
- at least one processor coupled to the memory, the at least one processor being configured:
- to receive signals from an eNodeB indicating a subset of CRS resources for at least one of radio link monitoring (RLM), reference signal received power (RSRP) measuring, or a combination thereof, the indicated subset of CRS resources comprising CRS resources having protected subframes during which interfering eNodeBs are prohibited from transmitting data;
- and
- to perform at least one of RLM, RSRP measuring, or a combination thereof based on the indicated subset of CRS resources.
