See also Fig. 2, it carries out the flow chart of a kind of method of adjacent cell measurement for terminal in a kind of LTE of the present invention system.It comprises:
S110: terminal receives the measurement control messages that network side issues;
S120: terminal is carried out common frequency measurement or different-frequency measure according to the metering system of appointment in the described measurement control messages to adjacent sub-district.
Below specifically introduce each step.
One, S110
Network side sending measuring control messages, described measurement control messages can be for system message or special measuring controlling message, and at this, the special measuring controlling message of indication is meant that terminal is under the connection status, and network side is issued the measurement control messages of terminal.In measuring control messages, comprise metering system and the information of adjacent cells of network side to the indication of adjacent sub-district.The metering system of adjacent sub-district is common frequency measurement or different-frequency measure.Information of adjacent cells can comprise the type of adjacent sub-district, the adjacent sub-district of same layer of the Serving cell that promptly adjacent sub-district is a terminal or the adjacent sub-district of different layer, comprise adjacent sub-district relevant information, as adjacent cell list, receive the needed information of message of adjacent district common channel (as the BCH channel) etc.When the metering system of appointment is different-frequency measure, measure control messages and can also comprise the information of measuring space (measurement gap), be used for measurement gap that terminal can appointment and carry out iso-frequency adjacent community and measure.
Two, S120
If the adjacent sub-district in the measurement control messages that receives is distinguished, also be that adjacent sub-district is not divided into co-frequency neighbor cell or iso-frequency adjacent community or with adjacent sub-district of layer or the different adjacent sub-district of layer or carry out other classification, terminal will determine that adjacent sub-district belongs to the same adjacent sub-district of layer or the adjacent sub-district of different layer of the Serving cell of this terminal.
Terminal is measured described adjacent sub-district according to the metering system of measuring appointment in the control messages.Below just be divided into four kinds of situations and introduce concrete measuring process respectively.
A: terminal to the adjacent sub-district of layer be measured as common frequency measurement, may be common frequency measurement to the measurement of the adjacent sub-district of different layer, also may be different-frequency measure.
When the metering system that receives the network side indication is common frequency measurement, terminal is to the common frequency measurement that is measured as with the adjacent sub-district of layer, if when terminal was not adjusted local terminal receiver frequency and just can be received the adjacent district common channel message of different layer, terminal was also carried out common frequency measurement to described different layer of adjacent sub-district.
When the metering system that receives the network side indication was different-frequency measure, terminal was carried out different-frequency measure to the adjacent sub-district of described different layer.
(1) the adjacent sub-district of same layer that issues refers to and Serving cell same frequency, same bandwidth; The adjacent sub-district of different layer refers to and Serving cell different frequency or different bandwidth;
UE is to the common frequency measurement that is measured as with the adjacent sub-district of layer; UE carries out common frequency measurement or different-frequency measure to the situation decision according to the adjacent sub-district of different layer to the adjacent sub-district of different layer.In Fig. 3 and Fig. 4, Cell2 is the same layer sub-district of Cell1, and UE1, UE2 are to the common frequency measurement that is measured as of Cell2.Cell3 is the different layer sub-district of Cell1, because the frequency range at cell3 place, adjacent sub-district drops on the scope interior (determination methods one) of the frequency range at UE1 place, in other words, the centre frequency of adjacent sub-district cell3 drops on the frequency range interior (determination methods two) of UE1, essence is meant that UE1 need not to adjust local terminal receiver frequency and just can receive cell3 common signal channel (as the BCH channel) message, and UE1 is to the common frequency measurement that is measured as of Cell3.If UE need adjust the common channel messages that local terminal receiver frequency could receive adjacent sub-district, then UE carries out different-frequency measure to this adjacent sub-district of different layer.As the be measured as different-frequency measure of UE2 to Cell3.Fig. 3, the bandwidth of UE1, UE2 is 10.625MHz, the SCH channel is positioned at the centre of transmission bandwidth, and has only one, at Fig. 3 in this case, can adopt determination methods one or adopt determination methods two to judge that can UE carry out common frequency measurement to the adjacent sub-district of different layer.Among Fig. 4, the bandwidth of UE1, UE2 is 10MHz, and when cell transmission bandwidths was 20MHz, there were two SCH channels a sub-district.At Fig. 4 in this case, can adopt determination methods one to judge that can UE carry out common frequency measurement to the adjacent sub-district of different layer.
(2) the adjacent sub-district of same layer that issues refers to and the Serving cell same frequency; The adjacent sub-district of different layer refers to different frequency.At this moment, UE is to the common frequency measurement that is measured as with the adjacent sub-district of layer; UE may be common frequency measurement to the measurement of the adjacent sub-district of different layer, also may be different-frequency measure.
With Fig. 5 is example, and Cell2, Cell4 are the same layer sub-district of Cell1, and UE1, UE2 are to the common frequency measurement that is measured as of Cell2, Cell4; Cell3 is the different layer sub-district of Cell1.Because the frequency range at cell3 place, adjacent sub-district drops on the scope interior (determination methods one) of the frequency range at UE1 place, in other words, the centre frequency of adjacent sub-district cell3 drops on the frequency range interior (determination methods two) of UE1, essence is meant that UE1 need not to adjust local terminal receiver frequency and just can receive cell3 common signal channel (as the BCH channel) message, and UE1 is to the common frequency measurement that is measured as of Cell3.If UE need adjust the common channel messages that local terminal receiver frequency could receive adjacent sub-district, then UE carries out different-frequency measure to this adjacent sub-district of different layer.As the be measured as different-frequency measure of UE2 to Cell3.
In sum, after UE receives message:
If network side indication is carried out common frequency measurement and issued with layer information of adjacent cells or/and different layer information of adjacent cells, then UE is to carrying out common frequency measurement with the adjacent sub-district of layer; UE judges according to whether needing to adjust the mode that local terminal receiver frequency do not receive the adjacent sub-district of different layer whether the measurement of the adjacent sub-district of different layer can be common frequency measurement, if can, then can carry out common frequency measurement.
If the network side indication is carried out different-frequency measure and issued different layer information of adjacent cells, then UE carries out different-frequency measure.
Terminal is carried out different-frequency measure in the measurement space of indication, described measurement space be indicate in the described measurement control messages that issues by network side or network side indicate issuing in the schedule information for described terminal distribution time domain and/or frequency domain resource.
In addition, terminal is carried out different-frequency measure in the predefined different-frequency measure time.Terminal can also be when detecting current idling-resource and carry out condition that different-frequency measure satisfied greater than I, and terminal is carried out different-frequency measure again.I carry out condition that different-frequency measure satisfies comprise the minimum time/time domain of different-frequency measure needs resource, etc.
From the above, can be that network side issues setting the opportunity that terminal is carried out different-frequency measure, also can be predefined, can also be to decide according to the current concrete resource of terminal.
B, to carrying out common frequency measurement with the adjacent sub-district of layer, different-frequency measure is carried out in the adjacent sub-district of different layer
(be referred to as with the adjacent sub-district of layer at first kind of definition mode no matter be with the adjacent sub-district of the adjacent cell/different layer of layer with the adjacent sub-district of Serving cell same frequency, be referred to as the adjacent sub-district of different layer with the adjacent sub-district of Serving cell different frequency) still (be referred to as with the adjacent sub-district of layer with the Serving cell same frequency and with the adjacent sub-district of bandwidth at second kind of definition mode, be referred to as the adjacent sub-district of different layer with the adjacent sub-district of Serving cell different frequency and/or different bandwidth), common frequency measurement is carried out in network side indication and with a layer information of adjacent cells, terminal is carried out common frequency measurement to described with the adjacent sub-district of layer if receive; If receive network side indication carrying out different-frequency measure and different layer information of adjacent cells, terminal institute carries out different-frequency measure to the adjacent sub-district of described different layer.
If the network side indication is carried out different-frequency measure and issued different layer information of adjacent cells, then UE carries out different-frequency measure.
Terminal is carried out different-frequency measure at the measurement space gap of indication, described measurement space be indicate in the described measurement control messages that issues by network side or network side indicate issuing in the schedule information for described terminal distribution time domain and/or frequency domain resource.
In addition, terminal is carried out different-frequency measure in the predefined different-frequency measure time.Terminal can also be when detecting current idling-resource and carry out condition that different-frequency measure satisfied greater than I, and terminal is carried out different-frequency measure again.I is carried out the condition that different-frequency measure satisfies and is comprised minimum time/time-domain resource of different-frequency measure needs etc.
With Fig. 6 is example, and Cell2 is the same layer sub-district of Cell1, and UE1, UE2 are to the common frequency measurement that is measured as of Cell2; Cell3 is the different layer sub-district of Cell1, and UE1, UE2 carry out different-frequency measure to Cell3.
C, UE may be common frequency measurement to the measurement with the adjacent sub-district of layer, also may be different-frequency measure; UE may be common frequency measurement to the measurement of the adjacent sub-district of different layer, also may be different-frequency measure.
The different-frequency measure that terminal receives the network side indication reaches with layer/different layer information of adjacent cells, different-frequency measure is carried out in the adjacent sub-district of described different layer, and receive with the adjacent district common channel message of layer if need to adjust local terminal receiver frequency, also carry out different-frequency measure with the adjacent sub-district of layer described.
The common frequency measurement that terminal receives the network side indication reaches with layer/different layer information of adjacent cells, to carrying out common frequency measurement with the adjacent sub-district of layer, and just can not receive the adjacent district common channel message of different layer if do not need to adjust local terminal receiver frequency, common frequency measurement is also carried out in the adjacent sub-district of described different layer.
(1) the adjacent sub-district of same layer that issues refers to and Serving cell same frequency, same bandwidth; The adjacent sub-district of different layer refers to different frequency or different bandwidth.
At this moment, UE may be common frequency measurement to the measurement with the adjacent sub-district of layer, also may be different-frequency measure; UE may be common frequency measurement to the measurement of the adjacent sub-district of different layer, also may be different-frequency measure.Design and scene such as Fig. 7: Cell2 is the same layer sub-district of Cell1, and UE2 is to the common frequency measurement that is measured as of Cell2, and UE1 is to the different-frequency measure that is measured as of Cell2; Cell3 is the different layer sub-district of Cell1, and UE1 is to the common frequency measurement that is measured as of Cell3; UE2 is to the different-frequency measure that is measured as of Cell3.
(2) the adjacent sub-district of same layer that issues refers to and the Serving cell same frequency; The adjacent sub-district of different layer refers to different frequency.
At this moment, UE may be common frequency measurement to the measurement with the adjacent sub-district of layer, also may be different-frequency measure; UE may be common frequency measurement to the measurement of the adjacent sub-district of different layer, also may be different-frequency measure.Equally also available scene shown in Figure 7 is explained.
That is to say, after UE receives message:
If the network side indication is carried out common frequency measurement and has been issued with layer information of adjacent cells or/and different layer information of adjacent cells, then UE for the adjacent sub-district of layer or/and the information of different layer information of adjacent cells, by judging whether UE needs to adjust the common channel information that local terminal receiver frequency receives adjacent sub-district and judge whether and can carry out common frequency measurement to the measurement of this sub-district, if do not need to adjust the common channel information that local terminal receiver frequency receives adjacent sub-district, then carry out common frequency measurement;
If network side indication is carried out different-frequency measure and has been issued with layer information of adjacent cells or/and different layer information of adjacent cells, then UE for the adjacent sub-district of layer or/and different-frequency measure is carried out in the adjacent sub-district of different layer.
Terminal is carried out different-frequency measure in the measurement space (measurement gap) of indication, described measurement space be indicate in the described measurement control messages that issues by network side or network side indicate issuing in the schedule information for described terminal distribution time domain and/or frequency domain resource.
In addition, terminal is carried out different-frequency measure in the predefined different-frequency measure time.Terminal can also be when detecting current idling-resource and carry out condition that different-frequency measure satisfied greater than I, and terminal is carried out different-frequency measure again.I is carried out the condition that different-frequency measure satisfies and is comprised minimum time/time-domain resource of different-frequency measure needs etc.
D, UE may be common frequency measurement to the measurement with the adjacent sub-district of layer, also may be different-frequency measure; UE is to the different-frequency measure that is measured as of the adjacent sub-district of different layer.
Layer/adjacent sub-district of different layer is regardless of first kind of define method of employing or at second kind of define method together, the different-frequency measure that terminal receives the network side indication reaches with layer/different layer information of adjacent cells, different-frequency measure is carried out in the adjacent sub-district of described different layer, and receive with the adjacent district common channel message of layer if need to adjust local terminal receiver frequency, also carry out different-frequency measure with the adjacent sub-district of layer described.The common frequency measurement that terminal receives the network side indication reaches with a layer information of adjacent cells, to carrying out common frequency measurement with the adjacent sub-district of layer.
Design and scene such as Fig. 8: Cell2, Cell4 are the same layer sub-district of Cell1, because UE1, UE2 can not all receive the BCH channel information of Cell2, Cell4, need to adjust the whole BCH channel informations that receive Cell2, Cell4 of receiver frequency ability of this terminal.Therefore, UE1, UE2 are to the different-frequency measure that is measured as of Cell2, Cell4, and UE3 is to the common frequency measurement that is measured as of Cell2; Cell3 is the different layer sub-district of Cell1, and UE1, UE2, UE3 are to the different-frequency measure that is measured as of Cell3.
After UE receives and measures control messages: if the network side indication is carried out common frequency measurement and issued with layer information of adjacent cells, then UE is for the information with the adjacent sub-district of layer, need judge whether and can carry out common frequency measurement the measurement of this sub-district, if can, common frequency measurement then carried out; If the network side indication is carried out different-frequency measure and issued different layer information of adjacent cells, then UE is a different-frequency measure for the measurement of the adjacent sub-district of different layer.
