Adopt embodiment five below, the technical scheme of said method embodiment is elaborated.Fig. 5 is the flow chart that the present invention controls the embodiment of the method five of semi-persistent scheduling implicit expression release function, and as shown in Figure 5, the method detailed process is as follows:
Step 501:eNB closes threshold value and door capable of being opened limit value according at least one setting in current area bandwidth, subframe proportioning type.
In this step, particularly, closing threshold value and door capable of being opened limit value can be arranged according at least one in current area bandwidth, subframe proportioning type by eNB.For example, a kind of concrete method to set up is:
When bandwidth of cell lower than or equal 5M, and subframe proportioning type is more than or equal at 2 o'clock, eNB door capable of being opened limit value is set to infinity, closes threshold value and is set to 20; When bandwidth of cell is more than or equal to 5M, and subframe proportioning type is less than or equal at 1 o'clock, and eNB door capable of being opened limit value is set to 2, closes threshold value and is set to 0.Above-mentioned just the present invention arranges an example of two threshold values, for the setting of threshold value, the invention is not restricted to this.
Step 502:UE sends the information of current area PDCCH channel resource to eNB.
In this step, a plurality of UE send the information of current area PDCCH channel resource separately to eNB.
Step 503:eNB compares current area PDCCH channel resource information and the default threshold value of closing.
In this step, eNB, after receiving the current area PDCCH channel resource information of each UE transmission, compares each current area PDCCH channel resource information and the default threshold value of closing.If the current area PDCCH channel resource information of object UE is less than or equal to, close threshold value, perform step 504; If current area PDCCH channel resource information is greater than, close threshold value, return to execution step 502.
When the current area of object UE PDCCH channel resource information is less than or equal to while closing threshold value, eNB sends the control information of the implicit expression release function of closing semi-persistent scheduling to this object UE, object UE receives the control information from the implicit expression release function of closing semi-persistent scheduling of eNB.Particularly, the process that eNB sends the control information of the implicit expression release function of closing semi-persistent scheduling to this object UE comprises the steps 504 and step 506.Correspondingly, UE receives process from the control information of the implicit expression release function of closing semi-persistent scheduling of eNB and comprises the steps 505 and step 507.
Step 504:eNB is to UE transmitting system broadcast.
In this step, know that the current area PDCCH channel resource information of an object UE is less than or equal to close after threshold value when eNB judgement, eNB is to this object UE transmitting system broadcast.In this system broadcast message, carry the corresponding relation that target group sign and implicit expression discharge cell, the value that implicit expression discharges cell is the first value.Particularly, in this system broadcast message, carry group operating list, in this group operating list, store a plurality of groups of signs and group content of operation corresponding to each group sign, in this group content of operation, comprise that implicit expression discharges cell, when the value of this implicit expression release cell is the first value, represent to close implicit expression release function, for example, above-mentioned the first value can be expressed as 1 or T.
Step 505:UE receives and stores the system broadcast message from eNB.
In this step, carry the corresponding relation that target group sign and implicit expression discharge cell in this system broadcast message, the value that this implicit expression discharges cell is the first value.Particularly, UE receives the system broadcast message from eNB, and stores the group operating list in this message, thereby stores the value that implicit expression corresponding to each group sign discharges cell.
Step 506:eNB sends the beep-page message that carries target group sign to UE.
In this step, eNB sends beep-page message to UE, carries target group sign in this beep-page message, the group by this UE of this message informing under it.
Step 507:UE receives the beep-page message that carries target group sign from eNB, according to the target group sign in beep-page message, and inquiry system broadcast, obtaining target group, to identify the value that corresponding implicit expression discharges cell be the first value.。
In this step, the value that UE discharges cell according to implicit expression is the first value, confirms to receive the control information of the implicit expression release function of closing semi-persistent scheduling.
UE, when receiving the control information of the implicit expression release function of closing semi-persistent scheduling, performs step 508.
Step 508:UE closes the implicit expression release function of semi-persistent scheduling.
In this step, particularly, UE closes the implicit expression release function of semi-persistent scheduling, when not having voice packet to send, according to current terminal configuration or network side indication, selects to adopt to send empty bag, or sends the noise bag of normal encoding and decoding.
After UE closes the implicit expression release function of semi-persistent scheduling, eNB can also open implicit expression release function again according to the situation of change of current area PDCCH channel resource.As shown in Figure 5, after step 508, can continue to carry out following steps:
Step 509:UE sends the information of current area PDCCH channel resource to eNB.
In this step, a plurality of UE send the information of current area PDCCH channel resource separately to eNB.
Step 510:eNB compares current area PDCCH channel resource information and default door capable of being opened limit value.
In this step, eNB, after receiving the current area PDCCH channel resource information that each UE sends, compares each current area PDCCH channel resource information and default door capable of being opened limit value.If the current area PDCCH channel resource information of object UE is more than or equal to door capable of being opened limit value, perform step 511; If current area PDCCH channel resource information is less than, close threshold value, return to execution step 509.
When the current area of object UE PDCCH channel resource information is more than or equal to while closing threshold value, eNB sends the control information of the implicit expression release function of opening semi-persistent scheduling to this object UE, object UE receives the control information from the implicit expression release function of the unlatching semi-persistent scheduling of eNB.Particularly, the process that eNB sends the control information of the implicit expression release function of opening semi-persistent scheduling to this object UE comprises the steps 511 and step 513.Correspondingly, UE receives process from the control information of the implicit expression release function of the unlatching semi-persistent scheduling of eNB and comprises the steps 512 and step 514.
Step 511:eNB is to UE transmitting system broadcast.
In this step, know that the current area PDCCH channel resource information of an object UE is more than or equal to close after threshold value when eNB judgement, eNB is to this object UE transmitting system broadcast.In this system broadcast message, carry the corresponding relation that target group sign and implicit expression discharge cell, the value that implicit expression discharges cell is the first value.Particularly, in this system broadcast message, carry group operating list, in this group operating list, store a plurality of groups of signs and group content of operation corresponding to each group sign, in this group content of operation, comprise that implicit expression discharges cell, when the value of this implicit expression release cell is the second value, represent to open implicit expression release function, for example, above-mentioned the second value can be expressed as 0 or F.
Step 512:UE receives and stores the system broadcast message from eNB.
In this step, carry the corresponding relation that target group sign and implicit expression discharge cell in this system broadcast message, the value that this implicit expression discharges cell is the second value.Particularly, UE receives the system broadcast message from eNB, and stores the group operating list in this message, thereby stores the value that implicit expression corresponding to each group sign discharges cell.
Step 513:eNB sends the beep-page message that carries target group sign to UE.
In this step, eNB sends beep-page message to UE, carries target group sign in this beep-page message, the group by this UE of this message informing under it.
Step 514:UE receives the beep-page message that carries target group sign from eNB, according to the target group sign in beep-page message, and inquiry system broadcast, obtaining target group, to identify the value that corresponding implicit expression discharges cell be the second value.
In this step, the value that UE discharges cell according to implicit expression is the second value, confirms to receive the control information of the implicit expression release function of opening semi-persistent scheduling.
UE, when receiving the control information of the implicit expression release function of opening semi-persistent scheduling, performs step 515.
Step 515:UE opens the implicit expression release function of semi-persistent scheduling.
In this step, UE opens the implicit expression release function of semi-persistent scheduling, particularly, opens after implicit expression release function, according to 3GPP agreement predetermined operation, after sending N default empty transmission of implicit expression release cell, enters implicit expression release condition.
The method of the control semi-persistent scheduling implicit expression release function that the present embodiment provides, by UE, to base station eNB, report the information of current area physical downlink control channel PDCCH channel resource, the information of reception current area, base station PDCCH channel resource, then base station eNB compares current area PDCCH channel resource and the default threshold value of closing, and be less than or equal to while closing threshold value and send the control information of closing implicit expression release function to UE at current area PDCCH channel resource, after the control information of closing implicit expression release function of UE reception from eNB, close the implicit expression release function of semi-persistent scheduling, and can make eNB compare current area PDCCH channel resource and default door capable of being opened limit value, and to UE, send the control information of opening implicit expression release function when current area PDCCH channel resource is more than or equal to door capable of being opened limit value, after the control information of UE reception from the unlatching implicit expression release function of eNB, open the implicit expression release function of semi-persistent scheduling.Thereby the implicit expression release function of having realized semi-persistent scheduling can be closed in limited time at current area PDCCH channel resource, avoided the PDCCH wasting of resources that adopts implicit expression release function to cause when PDCCH is resource-constrained, therefore improved bandwidth resources utilance, thereby improve network system capacity, and can reduce uplink interference while opening as required implicit expression release function after closing.
