Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
Because only supporting a reference signal power in system broadcast message in current agreement, exist when under a cell
When multiple reference signal powers, mobile terminal just can not accurately learn actual reference signal power, so as to cause its calculating
Downlink path loss is inaccurate.For this purpose, new technical solution is proposed in the embodiment of the present invention, when the actual reference signal power of discovery
When inconsistent with reference signal power for broadcast, mobile terminal is notified, so that mobile terminal is according to the actual reference signal
Power calculation path loss improves the accuracy of its path loss calculating, and then realizes and ensure that mobile terminal emits work(according to suitable uplink
Rate sends signal, and inaccurate technical problem is calculated to solve downlink path loss.It is specifically described below by way of each embodiment.
As shown in Fig. 2, for an idiographic flow schematic diagram of the method for sending information in the embodiment of the present invention, this method packet
Include following steps：
101, the reference signal power of mobile terminal access area is obtained, the reference signal power of the access area is institute
State the actual reference signal power that mobile terminal is presently in position.
As an alternative embodiment, step 101 may include：
The signal that mobile terminal is sent is received, and parses the signal, to obtain the transmission power for emitting the signal；
It is selected from multiple reference signal powers in the cell that above-mentioned mobile terminal is currently located, with above-mentioned transmitting work(
The most similar reference signal power of rate, and using the reference signal power selected as the reference of above-mentioned mobile terminal access area
Signal power.
Such as：Reference signal power includes in the cell that above-mentioned mobile terminal is currently located：Reference signal power 1, reference
Signal power 2 and reference signal power 3, and above-mentioned transmission power and reference signal power 3 are the most close, may be selected by this way
Go out reference signal power of the reference signal power 3 as above-mentioned mobile terminal access area.
Such as, network side monitors the access area of mobile terminal in real time, and obtains mobile terminal access area accordingly accordingly
Reference signal power.Since mobile terminal is in moveable scene, then may also include in this step：Judge described mobile whole
Whether the access area at end changes, and when judging result is to change, obtains connecing after the variation of the mobile terminal
Enter the reference signal power in region.For example, when the slave access area 1 of the mobile terminal is moved on to access area 2, at this moment can
To judge that the access area of mobile terminal changes, wherein network side monitors the access area of mobile terminal in real time, therefore can
To judge whether the access area of mobile terminal sends variation immediately.
Such as, for cell combining situation as shown in Figure 1, the cell 1 of new cell after mobile terminal, which enters, to be merged
When coverage area, the reference signal power for obtaining mobile terminal access area at this time is 1 reference signal power of cell
12.2dBm。
102, judge whether reference signal power and the reference signal power for broadcast of the access area are identical.It is logical
Often, after cell combining, the reference signal power of a cell before network side meeting selection combining in several cells is as use
In the reference signal power of broadcast (for example, being used for broadcast system message), the reference signal power for broadcast of this selection
The newly reference signal power for broadcast of cell can be considered as after cell combining.Still it is with cell combining situation shown in FIG. 1
Example, it is assumed that newly the reference signal power for broadcast of cell is the reference signal power of the cell 2 before merging, then when mobile whole
When end enters the coverage area of cell 1, the reference signal power of access area is distinguished with the reference signal power for broadcast
Correspond to the reference signal power of the reference signal power and cell 2 of cell 1.
103, when judging result is different, the reference signal power of the access area is sent to the mobile terminal,
So that the mobile terminal calculates downlink path loss according to the reference signal power of the access area.Such as, mobile terminal can be passed through
Reallocation message configures the reference signal power that message sends the access area to the mobile terminal for the first time.
By taking example in above-mentioned 102 as an example, then not due to the reference signal power of the reference signal power of cell 1 and cell 2
Together, then the lateral mobile terminal of network sends the reference signal power of access area, the i.e. reference signal power of cell 1.
The solution of the present invention is described from network side in above-described embodiment, next embodiment then should from subscriber terminal side description
Scheme.As shown in figure 3, for an idiographic flow schematic diagram of the message receiving method in the embodiment of the present invention.This method is used for
In mobile terminal, include the following steps：
201, mobile terminal receives the reference signal power for the mobile terminal access area that network side is sent, described to connect
The reference signal power for entering region is the actual reference signal power that the mobile terminal is presently in position；
Wherein, can be specifically to receive the mobile terminal reallocation message that network side is sent in this step, in the re-matching
Message includes the reference signal power of the mobile terminal access area；Can also be to receive the mobile end that network side is sent
End configures message for the first time, includes the reference signal power of the mobile terminal access area in the message of configuration for the first time.
202, mobile terminal calculates downlink path loss according to the reference signal power of the access area, so as to according under described
Walking along the street damage obtains the uplink transmission power of the mobile terminal.
As shown in figure 4, being then to further describe specific embodiments of the present invention from network side and end side both sides.It includes
Following steps：
301, after user terminal (User Equipment, UE) access cell, network side monitors the access area of the UE in real time
Domain.Wherein, which can be the mobile terminal in above-described embodiment.
302, when the reference signal power of the access area of the UE and for broadcasting (for example, being used for broadcast system message)
Reference signal power value difference or the access area of the UE change when changing so as to cause reference signal power, lead to
The PDSCH-ConfigDedicated notices UE crossed in UE reallocation messages (RRCConnectionReconfiguration) it answers
The reference signal power used.
As PDSCH-ConfigDedicated structures in embodiments of the present invention are：
That is, carry referenceSignalPower in PDSCH-ConfigDedicated, i.e. actual reference signal
Power.
303, after UE gets new reference signal power by reallocation message, its downlink path loss is recalculated, to more
Its new uplink transmission power.
It is described by above-described embodiment it is found that when, there are when multiple reference signal powers, using reality of the invention under single cell
Applying example can make UE accurately learn its reference signal power used, so as to more accurately calculate its lower walking along the street
Damage avoids the occurrence of because downlink path loss calculates the excessive or too small problem of the inaccurate ascending power occurred.
