Abstract
To facilitate sending a reference signal in a wireless communication environment, a transmitter sends a reference signal in a first time-frequency resource to a user equipment (UE); the transmitter sends data information in a first portion of a second time-frequency resource different from the first time-frequency resource to the UE; and the transmitter excludes data information from being sent in a second portion of the second time-frequency resource. The second portion of the second time-frequency resource is designated for use by another transmitter for sending another reference signal to the UE.
Claims16
A method performed by a base station for control an access point in a wireless communication network supporting coordinated multi-point transmission, comprising:
- determining, by the base station, whether the coordinated multi-point transmission is activated;
- and
- sending, by the base station, a first control information to an access point, wherein the first control information instructs the access point not to send data on a resource element and a user equipment is served simultaneously by the access point and the another access point.
A base station, comprising:
- a processor that determines that a coordinated multi-point transmission is activated;
- and
- a transmitter that sends first control information to an access point, wherein the first control information instructs the access point not to send data on a resource element where a reference signal is transmitted by another access point, and wherein a user equipment is served simultaneously by the access point and the another access point.
