Abstract
Disclosed embodiments may include an apparatus having one or more processors coupled to one or more computer-readable storage media. The one or more processors may be configured to transmit and/or receive channel state information reference signal (CSI-RS) resource configuration information, demodulation reference signals (DM-RS), uplink sounding reference signals (SRS), and power control parameters to support uplink coordinated multi-point (CoMP) operations. Other embodiments may be disclosed.
Claims20
A user equipment (UE), comprising:
- first circuitry to:
- identify a virtual cell identity based on a received indicator of the virtual cell identity, the virtual cell identity dynamically selected for association with an evolved universal mobile telecommunication system terrestrial radio access network (E-UTRAN), the virtual cell identity different from a physical layer cell identity corresponding to a cell of the E-UTRAN;
- and
- identify a seed based on a received indicator of the seed, the seed being different than the virtual cell identity and the physical layer cell identity;
- and
- second circuitry to:
- generate a demodulation reference signal parameter based on the virtual cell identity;
- and
- determine a cyclic shift for a demodulation reference signal based on the seed.
An evolved NodeB (eNB), comprising:
- first circuitry to:
- dynamically select a virtual cell identity for association with an evolved universal mobile telecommunication system terrestrial radio access network (E-UTRAN), the virtual cell identity different from a physical layer cell identity corresponding to a cell of the E-UTRAN;
- and
- select a seed, the seed being different than the virtual cell identity and the physical layer cell identity;
- and
- second circuitry to:
- provide, to a user equipment (UE), an indication of the virtual cell identity, the virtual cell identity for use by the UE in generating a demodulation reference signal parameter based on the virtual cell identity;
- provide, to the UE, an indication of the seed, wherein a cyclic shift parameter for use in determination of a cyclic shift for a demodulation reference signal is based on the seed.
A user equipment (UE), comprising:
- first circuitry to identify a UE-specific acknowledge and negative-acknowledge (AN) resource offset from a received indication of the UE-specific AN resource offset, wherein the UE-specific AN resource offset is different from a virtual cell identity used by the UE to generate a demodulation reference signal parameter;
- and
- second circuitry to determine a physical uplink control channel (PUCCH) resource based on the UE-specific AN resource offset, the PUCCH resource to be used for transmission of AN transmissions.
An evolved NodeB (eNB), comprising:
- first circuitry to select a user equipment (UE)-specific acknowledge and negative-acknowledge (AN) resource offset for a physical uplink control channel (PUCCH), wherein the UE-specific AN resource offset is different from a virtual cell identity used by the UE to generate a demodulation reference signal (DM-RS) parameter;
- and
- second circuitry to provide, to the UE, an indicator of the AN resource offset, the UE-specific AN resource offset for use in determination of a PUCCH resource for the AN transmissions based on the AN resource offset.
