Description

Method and base station that a kind of power is adjusted

Technical field

The present invention relates to moving communicating field, relate in particular to method and base station that a kind of power is adjusted.

Background technology

At time division duplex (Time Division Duplex, be called for short TDD) system or Long Term Evolution (Long Term Evolution, abbreviation LTE) in the TDD mode of operation of system, due to what adopt between uplink service and downlink business, be time-multiplexed mode, so the ascending-descending subframes of TDD system configuration is not relation one to one.According to the difference of up-downgoing service rate, 7 kinds of subframe configuration format are as shown in table 1.

Table 1 sub-frame configuration form signal table

Wherein, " D " represents to be exclusively used in the subframe of downlink transfer; " U " represents to be exclusively used in the subframe of uplink; " S " represents for descending pilot frequency time slot (Downlink Pilot Time Slot; referred to as DwPTS), protection interval (Guard Period; referred to as GP) and the special subframe in these three territories of uplink pilot time slot (Uplink Pilot Time Slot, referred to as UpPTS).

Descending sub frame is used for transmitting downlink business, and sub-frame of uplink is used for transmitting uplink service, a kind of ability of system transmission up-downgoing traffic carrying capacity that each uplink-downlink configuration is all corresponding.As can be seen from Table 1, the sub-frame configuration that downlink business ability is the strongest is configuration 5, and corresponding up-downgoing service rate ratio is 1: 9.The sub-frame configuration that uplink service ability is the strongest is configuration 0, and corresponding up-downgoing service rate ratio is 3: 2.Once determine any in 7 kinds of sub-frame configuration given in table 1, system will send ascending-descending subframes according to definite sub-frame configuration, and the ability that system sends up-downgoing traffic carrying capacity under the constant prerequisite of sub-frame configuration accordingly is also determined.

But under the given prerequisite of sub-frame configuration, if the scope of the traffic carrying capacity dynamic change of up-downgoing is larger, within the given time, the sub-frame configuration in original system can not reasonably adapt to new business demand.Therefore in order reasonably to utilize channel resource, meet the demand that up-downgoing service dynamic changes, can be in the situation that former sub-frame configuration be constant, subframe that wherein can dynamic-configuration is changed to its transmission direction, thereby change the ascending-descending subframes number in a radio frames, reach the object of Dynamic Matching up-downgoing traffic carrying capacity.

In existing standard, the transmitting power adjustment of upward signal comprises open-loop compensation and closed loop adjustment two parts.Wherein, closed loop adjustment is to terminal (User Equipment by base station, referred to as UE) transmission closed loop adjustment order (Transmit Power Control, referred to as TPC) carry out the size of the concrete power adjustment of notification terminal, the value of the power adjustment that the TPC order that terminal sends according to base station is indicated is dynamically adjusted the transmitting power of its upward signal.Concrete, TPC order is to UE's by the TPC field notice in descending control information format 0/3/4/3A (Downlink Control Information format0/3/4/3A, referred to as DCI format0/3/4/3A).There is 2bit in TPC territory in DCI format0/4, in DCIformat3, also there is 2bit in each TPC territory, the TPC order 0 of using respectively bit ' 00 ' to represent in TPC territory, the TPC order 1 representing in TPC territory with bit ' 01 ', the TPC order 2 representing in TPC territory with bit ' 10 ', the TPC order 3 representing in TPC territory with bit ' 11 '.Closed power adjustment amount corresponding to each TPC order is as shown in table 2.

The closed power adjustment amount corresponding to value of indicating in TPC territory in table 2DCIformat0/3/4

There is 1bit in each TPC territory in DCI format3A, the TPC order 0 of using respectively bit ' 0 ' to represent in TPC territory, the TPC order 1 representing in TPC territory with bit ' 1 '.Closed power adjustment amount corresponding to each TPC order is as shown in table 3.

The closed power adjustment amount corresponding to value of indicating in TPC territory in table 3DCIformat3A

In existing tdd systems, different communities or the sub-frame configuration of transmitting node are identical, and the transmission direction of the subframe at same position place, different districts is consistent.Like this, the sub-frame of uplink of different districts same position only can be subject to the interference of the sub-frame of uplink of other communities, this interference is less, as shown in Figure 1, the interference level that single locational subframe is subject to, namely disturb the ratio (Interference Over Thermal Noise, referred to as IoT) with respect to thermal noise to be no more than 25dB.The step-length of existing closed loop adjustment is 4dB to the maximum, just can revise the transmitting power of upward signal to resist this interference by existing closed loop adjustment.

But in the scene dynamically changing in tdd systems sub-frame configuration, between different districts, may there is different sub-frame configuration.Just may there is different transmission directions in the subframe that like this, is in same position in neighbor cell or different districts.For example, in the heterogeneous network scene being formed by macro base station (macro eNB) and femto base station (pico eNB), macro eNB is different with the sub-frame configuration of pico eNB, like this, subframe direction in the Serving cell of some macro eNB of subframe position place and pico eNB is identical, and in some position, the subframe direction in the Serving cell of macro eNB is up, and subframe direction in pico eNB Serving cell is descending, as shown in Figure 2.When there is this scene, the Serving cell of macro eNB can be subject to the interference of downlink transfer of the Serving cell of pico eNB in uplink direction.And also can be because of the difference of subframe transmission direction between different pico eNB, and the uplink that occurs a base station is subject to the situation of interference of the downlink transfer of another one base station, and this interference ratio is stronger.As shown in Figure 3, in some IoT of subframe position place maximum, can reach 60～65dB, and the number of sub frames that is subject to severe jamming obviously increases.If want to resist the interference between this base station and base station by promoting the transmitting power of upward signal, just need terminal to promote at short notice larger transmitting power.It is too short that but the closed power adopting in existing standard is adjusted step-length, cannot reach the target of fast lifting relatively high power at short notice.And because sub-frame configuration can dynamic-configuration, so it is also fixing to produce strongly disturbing subframe position.

Preferably, if newly-increased TPC offset value has four, be respectively M dB, N dB, O dB and P dB, M wherein, N, O and P are integer, indicate the signaling of offset to need 2bit, and can be with bit ' 00 ' indication M dB, with bit ' 01 ' indication N dB, with bit ' 10 ' indication O dB, with bit ' 11 ' indication P dB.When 2bit signaling indication offset value is M dB, the closed power adjustment amount of actual indication is exactly power adjustment and the offset value M dB sum of the TPC territory indication in DCI format0/3/4/3A.When 2bit signaling indication offset value is N dB, the closed power adjustment amount of actual indication is exactly power adjustment and the offset value N dB sum of the TPC territory indication in DCI format0/3/4/3A.When 2bit signaling indication offset value is O dB, the closed power adjustment amount of actual indication is exactly power adjustment and the offset value O dB sum of the TPC territory indication in DCI format0/3/4/3A.When 2bit signaling indication offset value is P dB, the closed power adjustment amount of actual indication is exactly power adjustment and the offset value P dB sum of the TPC territory indication in DCI format0/3/4/3A.

As shown in Figure 6, in the scene that macro and pico coexist, the sub-frame configuration of macro is configuration #0, and the sub-frame configuration of pico is configuration #1.According to the difference that is subject to the annoyance level of descending sub frame on sub-frame of uplink, the subframe of macro 2, subframe 3, subframe 7 and subframe 8 are divided into one group, subframe 4 and subframe 9 are divided into one group.Like this, the sub-frame of uplink on macro is divided into 2 groups.Macro can be by 1 bit RRC signaling or the offset value sum that to be the power adjustment shown in the power adjustment shown in table 2 and table 3 or table 2 and table 3 indicate with signaling corresponding to the TPC order of MAC signaling terminal in the TPC territory of DCI form.Or macro indicates concrete offset value by increase indication bit in DCI format0/4.If there is the bit of indication offset value in DCI format0/4, what the TPC order in the TPC territory of DCI form was corresponding is the offset value sum of the power adjustment shown in table 2 and table 3 and bit indication, if do not indicate the bit of offset value in DCI format0/4, what the TPC order in the TPC territory of DCI form was corresponding is the value of table 2 and table 3 correspondence.Or the bit number of each the TPC order of expansion in DCIformat3/3A is each TPC order increase by 2 bit on the basis of the indication bit of original TPC order, 4 offset values of this 2 bit correspondence.Each TPC order in DCI format3/3A has increased by 2 bits on the basis of present bit number like this.In DCI format3/3A, increase by 1 bit, be used for illustrating that in DCI format3/3A, each TPC order is existing bit number or has increased offset indication extension bit number afterwards simultaneously.Or, in DCI format3/3A, comprised original TPC order and increased the TPC order that offset value is indicated, it is original TPC order or the TPC order that has increased the indication of offset value that each TPC order simultaneously has extra physical layer signaling to indicate this TPC order.Or, while indicating closed power adjustment amount with DCI format3/3A, expansion part TPC order wherein, make each the TPC order after expansion comprise original TPC order and increase the TPC order that offset value is indicated, in DCI form, the TPC order of remainder still adopts existing indication bit, the adjustment relation of corresponding table 2 and table 3.Or the indication bit number of the TPC order in expansion DCI format0/3/4/3A increases by 1 bit, then with the TPC order indicated horsepower adjustment amount of expanding in DCI form on original indication bit basis.

Subframe 2 subframes 3, subframe 7 subframes 8 on pico can be divided into one group, and the indicating means of the concrete closed power adjustment amount using, referring to the method for the closed power adjustment amount that in above-mentioned indication macro, each sub-frame of uplink group is used, repeats no more here.

In another kind of implementation, after macro and pico can also first be divided into a plurality of subframe groups by sub-frame of uplink according to the difference that is subject to the annoyance level of descending sub frame on sub-frame of uplink, be fixed on the closed power adjustment amount Notification Method that uses existing standard to adopt in subframe 2 and subframe 7, namely by the TPC territory indication TPC order in DCI format0/4/3/3A, and according to table 2 and the definite closed power adjustment amount of table 3.And for macro for subframe 3, subframe 4, subframe 8 and subframe 9 and pico for subframe 3 and subframe 8, in the DCI format0/4/3/3A that macro and pico correspondingly send, have 1 bit be used to refer to TPC territory indication TPC order in DCI format0/4/3/3A corresponding be the offset value sum that power adjustment in table 2 and table 3 or the power adjustment shown in table 2 and table 3 and signaling are indicated.And this 1 bit can be carried on TPC territory, namely original TPC territory is increased to 1 bit.

Embodiment 4

In the standard of existing version, TPC order is to indicate to UE's by the TPC territory in DCIformat0/3/4/3A.Closed power adjustment amount corresponding to the value of indicating in each concrete TPC territory is as shown in table 2 and table 3.Base station is terminal configuration one group of closed power adjustment amount { A1, A2, A3, A4, A5, A6, A7, A8} by RRC signaling.

As shown in Figure 7, in full pico scene, pico1 is used sub-frame configuration #0, and pico2 is used sub-frame configuration #2.According to the difference that is subject to the annoyance level of descending sub frame on sub-frame of uplink, the subframe of pico1 2 and subframe 7 are divided into one group, subframe 3, subframe 4, subframe 8 and subframe 9 are divided into one group.Like this, the sub-frame of uplink on pico1 is divided into 2 groups.Pico1 can be used power adjustment corresponding in table 2 and table 3 or power adjustment { A1, A2, A3, A4, A5, A6, A7, the A8} of RRC signal deployment by RRC signaling or the MAC signaling terminal of 1 bit.Or pico1 can be the closed loop adjustment amount of which group by what increase in DCI format0/4/3/3A that the mode of 1 bit comes that notification terminal uses on each sub-frame of uplink, and this 1 bit can be carried on TPC territory, namely original TPC territory is increased to 1 bit.Particularly, when the value of notice signaling of 1 bit that is directed to subframe 2 and subframe 7 is for ' 0 ' time, represent that notification terminal is used the closed power adjustment amount of table 2 and table 3 correspondence in subframe 2 and subframe 7, when the value of notice signaling of 1 bit that is directed to subframe 3, subframe 4, subframe 8 and subframe 9 is for ' 1 ' time, represent that notification terminal is used the power adjustment { A1 of RRC signaling in subframe 3, subframe 4, subframe 8 and subframe 9, A2, A3, A4, A5, A6, A7, A8}.

Subframe 2 on pico2 and subframe 7 can be divided into one group, and the indicating means of the concrete closed power adjustment amount using, referring to the method for the closed power adjustment amount that in above-mentioned indication pico1, each sub-frame of uplink group is used, repeats no more here.

In another kind of implementation, after the difference that pico1 and pico2 can also be respectively first subject to the annoyance level of descending sub frame by sub-frame of uplink according to sub-frame of uplink is divided into a plurality of subframe groups, be fixed on the closed power adjustment amount Notification Method that uses existing standard to adopt in subframe 2 and subframe 7, namely by the TPC territory indication TPC order in DCI format0/4/3/3A, and according to table 2 and the definite closed power adjustment amount of table 3.And for subframe 3, subframe 4, subframe 8 and subframe 9, what have in the DCI format0/4/3/3A of pico1 notice that 1 bit is used to refer to TPC territory indication TPC order correspondence in existing DCI format0/4/3/3A is the closed power adjustment amount of which group.For example, when the value of the notice signaling of 1 bit sending for subframe 3 and subframe 8 be ' 0 ', represent that notification terminal is used the closed power adjustment amount of table 2 and table 3 correspondence in subframe 3 and subframe 8, when the value of the notice signaling of 1 bit of transmission is ' 1 ' on for subframe 4 and subframe 9, represent that notification terminal is used the closed power adjustment amount { A1 of RRC signaling in subframe 4 and subframe 9, A2, A3, A4, A5, A6, A7, A8}.

Concrete, the power adjustment of pico1 or pico2 notice be RRC signaling A1, A2, A3, A4, A5, A6, A7, which in A8} can be indicated by TPC order.Now TPC order should have 3bit, so need to be by the TPC command sets extension in original DCI format0/4/3/3A to 3bit.Especially, when carrying out indicated horsepower adjustment amount with DCI format3/3A, a plurality of TPC orders that comprise in DCI format3/3A can be different indication bit numbers.When pico1 or pico2 notification terminal 1 adopts the power adjustment of table 2 and table 3, corresponding TPC order is exactly the TPC order of existing format specification, in the time of adopt in many groups power adjustment of notifying in the present embodiment when pico1 or pico2 notification terminal 2 one group, corresponding TPC order is exactly the TPC order of expansion, so the TPC order indication bit number of terminal 1 and terminal 2 correspondences is different, but they can be indicated by DCIformat3/3A simultaneously.

Especially, when carrying out indicated horsepower adjustment amount with DCI format3/3A, a plurality of TPC orders that comprise in DCI format3/3A can be different indication bit numbers.When base station notification terminal 1 adopts the power adjustment of table 2 and table 3, corresponding TPC order is exactly the TPC order of existing format specification, when the notice in the 2 employing the present invention of base station notification terminal is organized a group in power adjustment more, corresponding TPC order is exactly the TPC order of expansion, so the TPC order indication bit number of terminal 1 and terminal 2 correspondences is different, but they can be indicated by DCI format3/3A simultaneously.
