Reference signal enhancement for shared cell
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.
1. 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.
2. The UE of claim 1 , wherein the DRS is a channel state information (CSI) RS (CSI-RS).
3. 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.
4. The one or more non-transitory computer-readable media of claim 3 , wherein the DRS is a channel state information (CSI) RS (CSI-RS).
5. The one or more non-transitory computer-readable media of claim 3 , wherein the cellular network is a coordinated multi point (CoMP) cellular network.
6. 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.
7. The UE of claim 6 , wherein the DRS is a channel state information (CSI) RS (CSI-RS).
8. The UE of claim 6 , wherein the UE is in a coordinated multi point (CoMP) cellular network.
9. 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.
10. The method of claim 9 , wherein the DRS is a channel state information (CSI) RS (CSI-RS).
11. The method of claim 9 , wherein the UE is in a coordinated multi point (CoMP) cellular network.
