example 1

[0090] Example 1: The scheduling parameter value corresponding to the scheduling function is: resource allocation type 0, new packet, single codeword, and codeword that has not been scheduled; at this time, the implementation process of frequency domain resource scheduling for UE described in this step like Figure 6 shown, including:

[0091] Step 601: Obtain the first subband in the subband set with the largest CQI value;

[0092] Step 602: Judging whether the two RBGs of the current subband are both occupied, if yes, acquire the next subband, and perform the judgment in step 602; otherwise, execute step 604.

[0093] Wherein, the acquisition of the next subband has different processing in different situations:

[0094]Wherein, when the current subband is the last subband in the subband set, then the acquisition of the next subband is the first subband in the subband set corresponding to the acquisition (current CQI value-1);

[0095] And when the current subband is not t...

example 2

[0112] Example 2: The scheduling function is: resource allocation type 1, new packet transmission, single codeword, and no scheduling has been performed on this codeword before; at this time, the implementation process of frequency domain resource scheduling for UE described in this step is as follows Figure 7 shown, including:

[0113] Step 701: Obtain the first subband in the subband set with the largest CQI value;

[0114] Step 702: Judging whether there is an idle PRB in the current subband, if yes, execute step 703; otherwise, acquire the next subband, and execute the judgment in step 702.

[0115] Wherein, the acquisition of the next subband has different processing in different situations:

[0116] Wherein, when the current subband is the last subband in the subband set, then the acquisition of the next subband is the first subband in the subband set corresponding to the acquisition (current CQI value-1);

[0117] And when the current subband is not the last subband ...

Abstract

The invention discloses a frequency domain resource scheduling method. A CQI (Channel Quality Indicator) storage structure is preset in the frequency domain resource scheduling method, and a corresponding subband set is set for each CQI value in the CQI storage structure. The frequency domain resource scheduling method also comprises the following steps of: receiving the CQI values of subbands, which are reported by UE (User Equipment) and updating the CQI storage structure according to the CQI values of the subbands; and carrying out frequency domain resource scheduling for the UE to be scheduled according to the CQI storage structure during frequency domain resource scheduling. The invention also discloses a frequency domain resource scheduling device. The frequency domain resource scheduling method and device can carry out scheduling processing with high efficiency at a high speed.

Description

technical field [0001] The present invention relates to the communication field, in particular to a frequency domain resource scheduling method and device. Background technique [0002] In the data transmission between the terminal UE and the network side, the network side needs to schedule frequency domain resources for the UE, so that the UE can implement data transmission with the network side on the frequency domain resources. [0003] In the prior art, when scheduling the frequency domain resources of the UE, it is generally implemented by traversing and retrieving the frequency domain resources. It is assumed that frequency domain resources are in units of subbands, and each subband will have its corresponding channel quality indicator, that is, a CQI value, within a period. The frequency-domain resource scheduling in the prior art is as follows: first, according to the CQI values ​​of the sub-bands, the sub-bands are sorted according to the order of the CQI values ​​...
