Abstract
A cell interference coordination method and a base station include a base station stopping sending other information other than pilot information after the base station switches to a dormant state from a work state. A cell interference coordination method and a terminal are also included. By means of the technical solution, the base station is enabled to send pilot information when in a dormant state, thereby avoiding bringing interference for other base stations, and also enabling a terminal to awaken the dormant base station according to the received pilot information as required.
Claims14
A method for cell interference coordination, comprising:
- receiving, from a designated time-frequency source and by a base station, an awakening request comprising a designated preamble sequence, upon which the base station switches from a dormant state to a work state;
- before the base station switches from the work state to the dormant state, sending, by the base station, an available time-frequency resource and an available set of preamble sequences of the base station;
- and
- after the base station switches from the work state to the dormant state, stopping sending other information other than pilot information.
A computer system, comprising:
- a non-volatile memory;
- and
- the computer system is configured to execute machine-readable instructions stored in the non-volatile memory to:
- control a base station to switch from a work state to a dormant state, wherein an available time-frequency resource and an available set of preamble sequences of the base station are sent before the base station switches from the work state to the dormant state;
- stop sending other information other than pilot information when the base station is in the dormant state;
- and
- control the base station to switch from the dormant state to the work state upon receiving an awakening request from a designated time-frequency resource, the awakening request comprising a designated preamble sequence.
