Abstract
The invention relates to a method for adjusting a physical downlink control channel (PDCCH). The method includes the steps that the minimum aggregation stage Taumin and the maximum aggregation stage Taumax of the PDCCH are determined according to the format of DCI of UE; Nbundled parameters used by the UE are determined according to received signals; the state statistics amount deltaPDCCH of the PDCCH is calculated according to the number NDAI of DCIs carried by Nbundled and a base station on the PDCCH; the aggregation stage of the PDCCH is firstly adjusted according to the deltaPDCCH, and when the present aggregation stage Tau is larger than the Taumax or smaller than the Taumin, the transmission power of the PDCCH is then adjusted according to the deltaPDCCH. After the embodiment is applied, the downlink control channel can be adjusted according to existing parameters, and accuracy can be guaranteed.
Description
Technical field
The application relates to communication technical field, more specifically, relates to a kind of method and apparatus of adjustment Physical Downlink Control Channel (PDCCH).
Background technology
In LTE system, PDCCH carries Downlink Control Information (DCI) information.DCI is used for controlling the functions such as the dispatching distribution of up-downgoing resource and ascending power.Therefore, the transmission performance of PDCCH channel directly has influence on the transmission performance of Physical Downlink Shared Channel (PDSCH) and Physical Uplink Shared Channel (PUSCH), guarantees that the throughput of the transmitting of PDCCH channel to whole LTE system is most important.
But in order to meet a large amount of data communication needs of user, PDCCH needs to carry multiple DCI in limited resource, and therefore the channel utilization of PDCCH is also extremely important.As can be seen here, the efficiency of transmission basis of guaranteeing PDCCH transmission reliability being improved PDCCH directly determines the performance of LTE system.
Related protocol specifies, PDCCH is upper can carry at least 1 DCI.The content of each DCI comprises the schedule information of downlink or uplink or up power control command etc.PDCCH is in the upper transmission of one or more control channel element (CCE), and a CCE is made up of 9 resource element groups (REG), and REG comprises 4 available Resource Block (RE).
The form of PDCCH is as shown in table 1, and PDCCH format represents the form of PDCCH in Table 1.
Table 1PDCCH form
| PDCCH?format | CCEs number | REG number | PDCCH bits number |
| 0 | 1 | 9 | 72 |
| 1 | 2 | 18 | 144 |
| 2 | 4 | 36 | 288 |
| 3 | 8 | 72 | 576 |
As can be seen from foregoing, the transmission of PDCCH needs first to determine PDCCH form, namely determines the number that PDCCH takies.Under normal circumstances, channel quality instruction (CQI) value that base station reports according to UE determines the form (i.e. PDCCH take the number of CCE) of PDCCH, and the number of CCE that then basis takies carries out rate-matched.
The CQI value reported as UE is higher, and namely channel condition is good, can configure and take less CCE to improve the code check of PDCCH channel, thus improves the channel utilization of PDCCH; The CQI value reported as UE is lower, and namely channel condition is poor, then distribute more CCE to reduce the code check of PDCCH channel, to improve the reliability of transmission, ensures that control information can correctly be transmitted.
Related protocol specifies, a public PDCCH can be made up of 4 or 8 CCE, and a specific PDCCH of UE can be made up of 1,2,4 or 8 CCE.If PDCCH is assigned with the transmission reliability that maximum CCE can't meet PDCCH, can only ensure that PDCCH correctly transmits by the transmitted power improving PDCCH.
Determine that the CQI indicating channel state that PDCCH channel aggregation grade mainly utilizes UE to feed back adjusts, to ensure the transmitting of PDCCH at present.Polymerization grade refers to the sequence number that in table one, PDCCH form is corresponding, determines that polymerization grade just can be determined to transmit PDCCH on several CCE.
The method adopted due to the radiation pattern, power control etc. of PDSCH with PDCCH is not identical, and CQI reflection is the channel quality of PDSCH, can not reflect the channel quality of PDCCH completely.Therefore directly use CQI to estimate that the channel quality of PDCCH can exist very large estimated bias, affect the transmission performance of PDCCH channel.
And adopt in prior art and utilize DTX testing result to adjust PDCCH channel aggregation grade.Although the transmission performance of PDCCH can be ensured, and optimize the resource utilization of PDCCH.But too rely on the testing result of DTX, the correctness of DTX detection method directly determines transmission reliability and the utilance of PDCCH.
