Abstract
Briefly, in accordance with one or more embodiments, two or more cells are configured to perform coordinated multipoint (CoMP) transmission for one or more user equipment devices with a common media access control (MAC) or a common radio resource control (RRC). Measurement information is received from the one or more user equipment devices. One or more of the cells may be deactivated, or one or more additional cells may be activated for coordinated multipoint transmission based at least in part on the measurement information.
Claims27
A method, comprising:
- configuring two or more cells comprising a single enhanced Node B (eNB) and one or more remote radio elements (RREs) in a distributed antenna system (DAS) deployment to perform coordinated multipoint (CoMP) transmission for one or more user equipment devices with a common media access control (MAC) or a common radio resource control (RRC), or combinations thereof, wherein the two or more cells have a same cell identification (ID) and different physical (PHY) attributes;
- selecting one of the two or more cells as a primary cell and at least another of the two or more cells as a secondary cell;
- receiving measurement information related to CoMP operation from the one or more user equipment devices on a feedback channel of the primary cell only, and from one or more secondary cells;
- and
- deactivating one or more of the cells or activating one or more additional cells for coordinated multipoint transmission based at least in part on the measurement information.
An apparatus, comprising:
- a radio-frequency transceiver;
- a processor coupled to the radio-frequency transceiver, wherein the processor is configured to cause the radio-frequency transceiver to:
- configure two or more cells comprising a single enhanced Node B (eNB) and one or more remote radio elements (RREs) in a distributed antenna system (DAS) deployment to perform coordinated multipoint (CoMP) transmission for one or more user equipment devices with a common media access control (MAC) or a common radio resource control (RRC), or combinations thereof, wherein the two or more cells have a same cell identification (ID) and different physical (PHY) attributes;
- select one of the two or more cells as a primary cell and at least another of the two or more cells as a secondary cell;
- receive measurement information related to CoMP from the one or more user equipment devices on a feedback channel of the primary cell only, and from one or more secondary cells;
- and
- deactivate one or more of the cells or activating one or more additional cells for coordinated multipoint transmission based at least in part on the measurement information.
An article of manufacture comprising a storage medium having instructions stored thereon that, if executed, result in:
- configuring two or more cells comprising a single enhanced Node B (eNB) and one or more remote radio elements (RREs) in a distributed antenna system (DAS) deployment to perform coordinated multipoint (CoMP) transmission for one or more user equipment devices with a common media access control (MAC) or a common radio resource control (RRC), or combinations thereof, wherein the two or more cells have a same cell identification (ID) and different physical (PHY) attributes;
- selecting one of the two or more cells as a primary cell and at least another of the two or more cells as a secondary cell;
- receiving measurement information related to CoMP operation from the one or more user equipment devices on a feedback channel of the primary cell only, and from one or more secondary cells;
- and
- deactivating one or more of the cells or activating one or more additional cells for coordinated multipoint transmission based at least in part on the measurement information.
