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: the terminal receives the measurement control message that network side issues;
S120: the terminal is carried out common frequency measurement or different-frequency measure according to the metering system of appointment in the said measurement control message to adjacent sub-district.
Below specifically introduce each step.
One, S110
Network side sending measuring control messages, said measurement control message can be for system message or special measuring controlling message, and at this, the special measuring controlling message of indication is meant that the terminal is under the connection status, and network side is issued the measurement control message at terminal.In measurement control message, 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 the terminal or the adjacent sub-district of different layer, comprise adjacent sub-district relevant information, like adjacent cell list, receive the needed information of message of adjacent district common channel (like the BCH channel) etc.When the metering system of appointment was different-frequency measure, measurement control message can also comprise the information of measuring space (measurement gap), was used for measurement gap that the terminal can appointment and carried out iso-frequency adjacent community and measure.
Two, S120
If the adjacent sub-district in the measurement control message 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, the terminal will confirm 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 at this terminal.
The terminal is measured said adjacent sub-district according to the metering system of appointment in the measurement control message.Below just be divided into four kinds of situation and introduce concrete measuring process respectively.
A: the terminal to the adjacent sub-district of layer be measured as common frequency measurement, possibly be common frequency measurement to the measurement of the adjacent sub-district of different layer, also possibly be different-frequency measure.
When the metering system that receives the network side indication is common frequency measurement; The terminal is to the common frequency measurement that is measured as with the adjacent sub-district of layer; If when the terminal was not adjusted local terminal receiver frequency and just can be received the adjacent district common channel message of different layer, common frequency measurement was also carried out to said different layer of adjacent sub-district in the terminal.
When the metering system that receives the network side indication was different-frequency measure, different-frequency measure was carried out to the adjacent sub-district of said different layer in the terminal.
(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 adjacent sub-district cell3 place 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, and essence is meant that UE1 need not to adjust local terminal receiver frequency and just can receive cell3 common signal channel (like 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.Like 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 possibly be common frequency measurement to the measurement of the adjacent sub-district of different layer, also possibly 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 adjacent sub-district cell3 place 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 (like 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.Like 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 adjusting 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.
Different-frequency measure is carried out in the measurement space of indication in the terminal, said measurement space be indicate in the said measurement control message that issues by network side or network side indicate issuing in the schedule information for said terminal distribution time domain and/or frequency domain resource.
In addition, different-frequency measure is carried out in the predefined different-frequency measure time in the terminal.The terminal can also be when detecting current idling-resource and carry out condition that different-frequency measure satisfied greater than I, and different-frequency measure is carried out at the terminal 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 different-frequency measure is carried out at the terminal, also can be predefined, can also be to decide according to the current concrete resource in 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 to 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 to 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, the terminal is carried out common frequency measurement to said 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 said 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.
Different-frequency measure is carried out at the measurement space gap of indication in the terminal, said measurement space be indicate in the said measurement control message that issues by network side or network side indicate issuing in the schedule information for said terminal distribution time domain and/or frequency domain resource.
In addition, different-frequency measure is carried out in the predefined different-frequency measure time in the terminal.The terminal can also be when detecting current idling-resource and carry out condition that different-frequency measure satisfied greater than I, and different-frequency measure is carried out at the terminal 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 possibly be common frequency measurement to the measurement with the adjacent sub-district of layer, also possibly be different-frequency measure; UE possibly be common frequency measurement to the measurement of the adjacent sub-district of different layer, also possibly be different-frequency measure.
The different-frequency measure that the 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 said different layer; And, also carry out different-frequency measure with the adjacent sub-district of layer to said if need adjustment local terminal receiver frequency to receive with the adjacent district common channel message of layer.
The common frequency measurement that the 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 need not adjust local terminal receiver frequency, common frequency measurement is also carried out in the adjacent sub-district of said 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 possibly be common frequency measurement to the measurement with the adjacent sub-district of layer, also possibly be different-frequency measure; UE possibly be common frequency measurement to the measurement of the adjacent sub-district of different layer, also possibly 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 possibly be common frequency measurement to the measurement with the adjacent sub-district of layer, also possibly be different-frequency measure; UE possibly be common frequency measurement to the measurement of the adjacent sub-district of different layer, also possibly be different-frequency measure.Equally also available scene shown in Figure 7 is explained.
That is to say, after UE receives message:
