Abstract
In embodiments, apparatuses, methods, and storage media may be described for distinguishing, by a user equipment (UE), a reference signal (RS) transmitted by a cell that may have a same identifier (ID) as another cell in a network. In embodiments, a muting pattern, a time offset, or a virtual cell identifier (VCID) may be used to generate an RS sequence or RS resource allocation.
Claims11
A user equipment (UE) comprising:
- receive circuitry to receive a discovery reference signal (DRS), wherein the DRS is a DRS transmitted by a first transmit station in a first cell, wherein the first transmit station has a same physical cell identifier (PCID) as a second transmit station in a second cell;
- reference signal (RS) circuitry coupled with the receive circuitry, the RS circuitry to:
- identify configuration information having a configuration index and a time-domain offset parameter associated with the DRS;
- and
- perform, based on the time-domain offset parameter, a measurement related to the DRS;
- and
- transmit circuitry coupled with the RS circuitry, the transmit circuitry to transmit, to an evolved NodeB (eNB), the measurement and the configuration index,
- wherein the time-domain offset parameter is related to a subframe offset.
One or more non-transitory computer-readable media comprising instructions to cause a user equipment (UE) in a cellular network, upon execution of the instructions by one or more processors of the UE, to:
- identify a received discovery reference signal (DRS), wherein the DRS is a DRS transmitted by a first transmit station in a first cell, wherein the first transmit station has a same physical cell identifier (PCID) as a second transmit station in a second cell;
- identify configuration information having a configuration index and a time-domain offset parameter associated with the DRS;
- perform, based on the time-domain offset parameter, a measurement related to the DRS;
- and
- transmit, to an evolved NodeB (eNB), the measurement and the configuration index,
- wherein the time-domain offset parameter indicates a subframe offset.
A user equipment (UE) comprising:
- one or more processors;
- and
- one or more non-transitory computer-readable media comprising instructions that, when executed by the one or more processors, cause the UE to:
- identify configuration information having a configuration index and an offset parameter, wherein the offset parameter indicates a subframe offset;
- identify a received discovery reference signal (DRS), wherein the DRS is a DRS transmitted by a first transmit station in a first cell, wherein the first transmit station has a same physical cell identifier (PCID) as a second transmit station in a second cell;
- perform, based on the offset parameter, a measurement related to the DRS;
- and
- transmit, to an evolved NodeB (eNB), the measurement and the configuration index.
A method comprising:
- identifying, by a user equipment (UE), configuration information having a configuration index and a time-domain offset parameter;
- identifying, by the user equipment (UE), a received discovery reference signal (DRS), wherein the DRS is a DRS transmitted by a first transmit station in a first cell, wherein the first transmit station has a same physical cell identifier (PCID) as a second transmit station in a second cell;
- performing, by the UE based on the time-domain offset parameter, a measurement related to the DRS;
- and
- transmitting, by the UE, to an evolved NodeB (eNB), the measurement and the configuration index,
- wherein the time-domain offset parameter is related to a subframe offset.
