Embodiment
For resource overhead and the power consumption of saving the terminal; The embodiment of the invention provides the blind checking method of a kind of PDCCH; In this method, the terminal needs to judge the PDCCH data that whether have this terminal in this Boolean Search space before blind Detecting is carried out in the Boolean Search space; If do not exist, then blind Detecting is not carried out in this Boolean Search space.
Referring to Fig. 1, the blind checking method of the PDCCH that the embodiment of the invention provides specifically may further comprise the steps:
Step 10: the signal at corresponding physical resource location place, current Boolean Search space is extracted in the terminal before blind Detecting is carried out in current Boolean Search space;
Step 11: the PDCCH data at this terminal are confirmed in current Boolean Search space, whether to exist according to the performance number of the signal that extracts in the terminal;
Step 12: the blind Detecting to current Boolean Search space is abandoned in the terminal when confirming in current Boolean Search space, not have the PDCCH data at this terminal.
In the step 10, the signal at corresponding physical resource location place, current Boolean Search space is extracted at the terminal, and its concrete realization can be following:
The pairing resource unit group in current Boolean Search space (REG) is confirmed at the terminal; Extract the signal among each REG that confirms; Here, can confirm the pairing REG in current Boolean Search space according to the index value in predefined Boolean Search space and the corresponding relation of REG sign.
Accordingly, the PDCCH data at this terminal are confirmed in current Boolean Search space, whether to exist according to the performance number of the signal that extracts in the terminal in the step 11, and its concrete realization can be following:
Calculate from the total power value of the signal of this REG extraction for pairing each REG in current Boolean Search space at the terminal, and confirm whether there are the PDCCH data in this REG according to this total power value;
The PDCCH data at this terminal are confirmed whether to exist in the current Boolean Search space according to the number of the REG that does not have the PDCCH data that confirms in the terminal.
Above-mentioned basis confirms whether there are the PDCCH data in this REG from the total power value of the signal that REG extracts, and its concrete realization can be adopted following dual mode:
First kind, whether the performance number of the pilot signal that the terminal is confirmed to receive and the difference between this total power value greater than predefined first power threshold, if, then confirm not have the PDCCH data in this REG, otherwise, confirm to exist in this REG the PDCCH data;
Here, pilot signal can be: the pilot signal in the REG, or carry the nearest pilot signal that Resource Unit carried of this REG of Resource Unit middle distance of pilot signal, also promptly nearest pilot signal apart from this REG.
Second kind, this total power value is confirmed greater than predefined second power threshold in the terminal whether, if, then confirm to have the PDCCH data in this REG, otherwise, confirm not exist in this REG the PDCCH data.
Above-mentioned first power threshold is the performance number greater than 0; First power threshold can be confirmed through emulation; Concrete emulation mode is following: receive business datum signal and pilot signal that base station side is sent for many times through PDCCH, the difference between the performance number of the business datum signal that statistics receives at every turn and the performance number of pilot signal; With the maximum of repeatedly adding up the difference that obtains, confirm as first power threshold.
Above-mentioned second power threshold is the performance number greater than 0; Second power threshold can be confirmed through emulation; Concrete emulation mode is following: receive the business datum signal that base station side is sent for many times through PDCCH; The maximum of the performance number of the business datum signal that statistics receives is confirmed as second power threshold with this maximum.
The PDCCH data at this terminal are confirmed whether to exist in the current Boolean Search space according to the number of the REG that does not have the PDCCH data that confirms in above-mentioned terminal, and its concrete realization can be adopted following dual mode:
First kind, whether the number of the REG that does not have the PDCCH data that terminal judges is confirmed surpasses predefined number threshold value, if then confirm not exist in the current Boolean Search space PDCCH data at this terminal; Otherwise, confirm in the current Boolean Search space to exist the PDCCH data at this terminal.
Second kind; Whether the number of the REG that does not have the PDCCH data that terminal judges is confirmed surpasses predefined number threshold value; When the number of judging said REG surpasses said number threshold value; Confirm the channel condition of current PDCCH, confirm that according to channel condition the result confirms whether to exist in the current Boolean Search space PDCCH data at this terminal;
When the number of judging said REG surpasses said number threshold value, confirm the PDCCH data at this terminal of existence current Boolean Search space in.
Here, confirm that according to channel condition the result confirms whether to exist in the current Boolean Search space PDCCH data at this terminal, its concrete implementation method is following:
Whether channel quality indication (CQI) value of confirming current PDCCH is greater than the predefined CQI value that is used to define the channel condition quality; If; Then confirm not exist in the current Boolean Search space PDCCH data at this terminal; Otherwise, confirm in the current Boolean Search space to exist the PDCCH data at this terminal.Certainly; Can also confirm the quality of the channel condition of current PDCCH according to other channel quality parameter; When the channel condition of confirming current PDCCH is better; Confirm not exist in the current Boolean Search space PDCCH data at this terminal, when the channel condition of confirming current PDCCH is relatively poor, confirm to exist in the current Boolean Search space PDCCH data at this terminal.
In the step 12, when confirming in current Boolean Search space, to have the PDCCH data at this terminal at the terminal, data balancing and decoded operation are carried out to the data in the current Boolean Search space in the terminal.
In the step 12, after the blind Detecting to current Boolean Search space is abandoned at the terminal, with the next Boolean Search space in current Boolean Search space as current Boolean Search space, and execution in step 10-step 12.
