As shown in fig. 1, which is a schematic diagram of an implementation flow of a method for sending energy saving information according to an embodiment of the present invention, the method may include:
and S11, when the first base station determines that the first base station is to enter the energy-saving state, the first base station sends the energy-saving resource request to the second base station.
In one embodiment, the first base station may determine whether the first base station satisfies a condition for the energy-saving base station to enter the energy-saving state according to a preset determination condition, and if the first base station satisfies the condition, the first base station determines that the first base station will enter the energy-saving state.
In another embodiment, a decision node such as a network manager can judge whether the first base station meets the condition that the energy-saving base station enters the energy-saving state according to a preset judgment condition, if so, a notification message for entering the energy-saving state is sent to the first base station, and the first base station determines that the first base station enters the energy-saving state according to the received notification message.
The first base station may send the energy-saved resource request to the second base station when determining that the first base station is to enter the energy-saving state. The second base station may include a neighboring base station of the first base station, or a neighboring base station of a neighboring base station and the like that may be affected by the first base station entering the energy saving state.
The energy-saving resource request is initiated by the energy-saving base station, and the implementation manner may be a single message, or may multiplex an existing message, including but not limited to an eNB (base station) DU Configuration update message, and the like, and the sending mode may be direct transmission, or may be forwarding through another node.
In the embodiment of the present invention, in order to implement finer-grained energy saving control, the energy-saved resource request may carry the first energy-saving resource information.
Wherein the first energy saving resource information may include at least one of:
(1) the starting time of the energy saving state.
The starting time of the energy saving state may be an absolute time, such as XX minutes in XX of 20 months in 8 months in 2018, or a system frame number in the mobile communication system, or other marks capable of determining time absolutely or relatively.
(2) End time of energy saving state.
Similar to the start time of the energy saving state, the end time of the energy saving state may be an absolute time, such as XX minutes XX of 20 months 8 and 8 months in 2018, or a system frame number in the mobile communication system, or other markers that can determine time absolutely or relatively.

In the embodiment of the present invention, the video resource block corresponding to the energy saving state refers to a time domain and a frequency domain resource block on an air interface.
The representation manner in the time domain may be: the subframe number, symbol position, etc. mark the start time. For example one resource block in the time domain of 3ms and in the frequency domain of 20 Mhz.
Generally speaking, in order to achieve the energy saving function, the resource block corresponds to one physical working unit, and when the resource block saves energy, the corresponding physical working unit enters a sleep state.
The dormant granularity of the time-of-flight resources is different with a specific system, and particularly for an NR (New Radio, New air interface) system, the minimum allocation granularity of the resources can reach an OFDM (orthogonal frequency division multiplexing) symbol level, so that the corresponding time granularity can reach μ s; for LTE systems, the minimum scheduling granularity of a resource is at the PRB (0 physical resource block) level, and the corresponding time granularity is at the ms level.
The granularity of frequency domain resource dormancy includes any of: frequency bandwidth, number of PRBs, number of REs (resource elements), number of subcarriers, etc.

There are various ways of confirming, for example, the number of the corresponding resource block in the resource block set, or no content, etc. In an embodiment, the energy saving resource request acknowledgement message carries second energy saving resource information acknowledged by the second base station, which indicates an acceptance set of the first energy saving resource information sent by the first base station by the second base station.
In another embodiment, after receiving an energy-saving resource request sent by a first base station, a second base station determines a resource block set corresponding to an energy-saving state of the first base station according to its own load, etc. to obtain second energy-saving resource information, and an energy-saving resource request acknowledgement message returned to the first base station carries the second energy-saving resource information, where the second energy-saving resource information may be the same as or different from the first energy-saving resource information.
