Embodiment one
The PUCCH circule power control methods of the present invention are described in detail from user equipment (User Equipment, UE) angle for the present embodiment.
Fig. 1 is the schematic flow sheet of the PUCCH circule power control methods of one embodiment of the invention.As shown in figure 1, the PUCCH circule power control methods comprise the following steps：
101, DCIx is received in present sub-frame, the DCIx carries transmitting power control TPC command；
Specifically, UE obtains DCIx, the DCIx can be DCI 1A, DCI IB, DCI ID, DCI 1, DCI 2A, DCI 2 etc. for example by blind Detecting PDCCH channels.DCIx includes TPC command field, and the value of the field can be 0,1,2 or 3 etc..
Whether 102, it is empty inspection DCIx to judge the DCIx;
Specifically, UE can be using default any-mode come received in judgment step 101
Whether DCIx is empty inspection DCIx, such as UE judges that PUCCH whether has been carried out in the preset period of time before present sub-frame to be sent.Not to judging whether the concrete mode for being empty inspection DCIx is limited DCIx in the present embodiment.
103, if the DCIx, which is empty inspection DCIx, Lost, abandons the TPC command that the DCIx is carried；If the DCIx is not empty inspection DCIx, PUCCH power controls are carried out according to the TPC command.
Specifically, if knowing that DCIx is that Lost abandons the DCIx if void examines DCIx , by step 102 judgement, the TPC command not according to entrained by the DCIx carries out PUCCH power controls；If judging to know that DCIx is not empty inspection DCIx by step 102, then the DCIx is parsed, the TPC orders in DCIx are extracted, and according to the mapping relations between known TPC command and adjusting step, it is determined that the corresponding adjusting step of the TPC command extracted.More specifically, table 1 is the mapping relations of TPC command and adjusting step as defined in current agreement.
Table 1
As shown in table 1, if the TPC command extracted from DCIx is " 0 ", UE is current
On the basis of PUCCH Power Control aggregate-values, add up " -1 ", i.e., PUCCH transmit powers are turned down into IdB;If the TPC command extracted from DCIx is " 1 ", UE adds up " 0 " on the basis of current PUCCH Power Control aggregate-values, that is, keeps PUCCH transmit powers constant；If the TPC command extracted from DCIx is " 2 " or " 3 ", UE adds up " 1 " or " 3 " on the basis of current PUCCH Power Control aggregate-values, i.e., PUCCH transmit powers is heightened into IdB or 3dB.
According to the PUCCH circule power control methods of above-described embodiment, because user equipment is after DCIx is received, whether judge received DCIx is empty inspection DCIx, and according only to the TPC command entrained by the DCIx of non-empty inspection, PUCCH Power Control aggregate-values are updated, PUCCH Power Controls are carried out, so as to realize the PUCCH power adjusting amplitudes indicated according to base station, the PUCCH transmit powers regulation of user equipment is carried out, the degree of accuracy and the validity of Physical Uplink Control Channel power control is improved.
Specifically, by taking a concrete scene as an example, the PUCCH circule power control method phases of above-described embodiment are illustrated
For the beneficial effect of prior art.
For example：UE does not carry out PUCCH transmissions within a period of time, due to the time it is longer it is usual there is certain DCI void inspection, such as it is empty to examine to 8 DCIx.Assuming that in this 8 empty inspection DCIx, the probability that the value of 4 kinds of TPC commands shown in table 1 occurs is identical, then the sequence that the corresponding adjusting step of 8 TPC commands is formed is： { 3 , -1 , 0, 1 , 1 , 3 , 0, -1 } .
According to prior art, PUCCH power adjustings are directly carried out according to the TPC command that the DCIx received is carried, then within this time, UE PUCCH Power Control aggregate-values improve 6dB.Therefore when UE carries out PUCCH transmissions again, UE can determine transmit power according to the PUCCH Power Control aggregate-values improved after 6dB, i.e. PUCCH transmit powers are excessive.Although base station is after the PUCCH for receiving UE sends signal, for example, channel quality is indicated（Channel Quality Indicator, CQI) request, uplink scheduling request instruction (Schduling Request Indication, SRI) or confirmation message（Acknowledge, ACK) etc., the PUCCH transmit powers of the UE can be reduced by issuing DCIx, but still can be interior for some time, because the PUCCH transmit powers of the UE are excessive, and the interference to other UE PUCCH signals is caused, so as to cause other UE up CQI/SRI/ACK to feed back inaccurate, cause flow mutation or the abnormal logout of user etc..And by using the PUCCH circule power control methods of the above embodiment of the present invention, then can effectively reduce the drawbacks described above produced due to empty inspection DCIx.
Embodiment two
On the basis of above-described embodiment, judge whether DCIx is the empty concrete mode for examining DCIx there is provided a kind of in the present embodiment.
Fig. 2 is the schematic flow sheet of the PUCCH circule power control methods of another embodiment of the present invention.As shown in Fig. 2, the PUCCH circule power control methods comprise the following steps：
201, UE receive in present sub-frame and carry the DCIx of TPC command;
202, UE judge whether present sub-frame receives descending control information format 0 (DCI0)；If not receiving, step 203 is performed;If receiving, step 204 is performed;
203, the TPC command carried according to the DCIx of present sub-frame carries out PUCCH power adjustings, and terminates flow；
The TPC command that 204 , Lost are abandoned in DCIx, and terminate flow.
According to the PUCCH circule power control methods of the present embodiment, due in actual applications, in a carrier wave UE Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH) send and
PUCCH transmissions are typically what mutual exclusion occurred, and the scene that the UE long periods do not have PUCCH to send is often as caused by the PUSCH of connection transmissions.Therefore, UE judges whether identical subframe also has DCI0 scheduling while DCIx is received, that is, judges whether to receive that base station issues is used for the DCI0 for indicating that UE demodulate correspondingly business datum message on subsequent PUSCH.If receiving DCI0, can determine that received DCIx is empty inspection DCIx, so as to effectively reduce influences of the empty inspection DCI to UE PUCCH transmit powers.
Further, when UE performs PUCCH power controls according to above-mentioned steps 201-204, base station performs following flow when sending DCIx：
If there is DCIx to be sent in present sub-frame, judge that the present sub-frame whether there is DCI0 to be sent, the DCIx carries TPC command；
If in the absence of the DCI0 to be sent, sending the DCIx;If there is the DCI0 to be sent, the TPC in the DCIx is forced to be set to not adjust PUCCH transmit powers, i.e., 1, then retransmit the DCIx.After the arrival for waiting PUCCH power control demands next time, for example, the PUCCH signals of UE transmissions, the new effective TPC of carrying of regeneration DCIx are received again.
By sending DCIx in the manner described above by base station so that UE is using above-described embodiment
During PUCCH circule power control methods, the DCIx that base station is issued will not be mistaken for empty inspection DCIx, the validity and accuracy of PUCCH power controls is further increased.
Embodiment three
On the basis of any of the above-described embodiment, PUCCH circule power control methods are further comprising the steps of：Judge the duration not added up to the PUCCH Power Controls aggregate-value, if reach predetermined threshold value；
If reaching, the PUCCH Power Controls aggregate-value is reset.
Fig. 3 is the schematic flow sheet of the PUCCH circule power control methods of another embodiment of the present invention.As shown in Fig. 3, the PUCCH circule power control methods comprise the following steps：
301, UE receive in present sub-frame and carry the DCIx of TPC command;
302, UE judge whether present sub-frame receives descending control information format 0 (DCI0)；If not receiving, step 303 is performed;If receiving, step 305 is performed;
303, the TPC command carried according to the DCIx of present sub-frame carries out PUCCH power adjustings；Step 304 is performed afterwards;
304, the duration not added up to PUCCH Power Control aggregate-values is reset, and terminate stream
Journey；
Specifically, for example by setting a timer to record the duration not added up to PUCCH Power Control aggregate-values in UE.The timer initial value is 0, start the timer when UE access networks, and UE to PUCCH Power Controls aggregate-value when carrying out cumulative every time, by the timer clear 0, how long interior PUCCH Power Control aggregate-values are not added up continuously so that the duration of the timer is used to recording.
The TPC command that 305, Lost are abandoned in DCIx；Step 306 is performed afterwards;
306, whether judgement does not reach predetermined threshold value to the duration that PUCCH Power Control aggregate-values are added up；If it is not, then terminating flow；If so, then performing step 307;
Specifically, UE is stored with a predetermined threshold value, and the predetermined threshold value both can directly be configured in UE, and can also issued from base station to UE, without limitation in the embodiment of the present invention.Also, the predetermined threshold value can be arranged as required to as any duration, for example, 30 seconds.UE judges whether the duration not added up to PUCCH Power Control aggregate-values is more than or equal to predetermined threshold value according to the duration of timer record, if it is not, then terminating flow；
307, PUCCH Power Controls aggregate-value is reset, the duration not added up to PUCCH Power Control aggregate-values reset, and terminate flow.
Specifically, if judging to know that the duration for not adding up to PUCCH Power Control aggregate-values is more than or equal to predetermined threshold value by step 306, PUCCH Power Controls aggregate-value is reset, i.e.,：UE PUCCH transmit powers are reverted to default power during UE access networks.
Flow shown in above-mentioned Fig. 3 only as UE on the basis of above-described embodiment one or two, with reference to judge whether need to PUCCH Power Controls aggregate-value reset an example.
In another example, UE is also provided with a cycle timer, and when the cycle timer is overtime, UE judges whether do not reach predetermined threshold value to the duration that the PUCCH Power Controls aggregate-value is added up.If so, then resetting PUCCH Power Controls aggregate-value, and reactivate cycle timer；If it is not, not handling PUCCH Power Control aggregate-values then, cycle timer is reactivated.Wherein, the duration of the cycle timer can arbitrarily be set as needed, for example：It is set to the 1 ms (durations of one subframe of correspondence）, then judge whether that PUCCH Power Controls aggregate-value need to be reset in each subframe；Is is may be arranged as, then the judgement for once whether needing to reset to PUCCH Power Controls aggregate-value is performed at interval of Is.
According to the PUCCH circule power control methods of above-described embodiment, due to judging not to PUCCH power controls
The duration that aggregate-value processed is added up, if reach predetermined threshold value, and when reached, will be described
PUCCH Power Controls aggregate-value reset, further avoid due to UE cross for a long time do not carry out PUCCH transmissions caused by PUCCH transmit powers it is too high.
