example 1

[0090] Example 1: The scheduling parameter values ​​corresponding to the scheduling function are: resource allocation type 0, newly transmitted packet, single codeword, codeword has not been scheduled; at this time, the implementation process of frequency domain resource scheduling for the UE described in this step Such as Image 6 Shown, including:

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

[0092] Step 602: Determine whether the two RBGs of the current subband are both occupied, if yes, obtain the next subband, and perform the determination in step 602; otherwise, perform 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, acquiring the next subband is acquiring the first subband in the subband set corresponding to (current CQI value -1);

[0095] However, when the current subband is not t...

example 2

[0112] Example 2: The scheduling function is: resource allocation type 1, new transmission packet, single codeword, and the codeword has not been scheduled before; at this time, the implementation process of frequency domain resource scheduling for the UE described in this step is as follows: Figure 7 Shown, including:

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

[0114] Step 702: Determine whether there is an idle PRB in the current subband, if yes, perform step 703; otherwise, obtain the next subband, and perform the determination of 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, acquiring the next subband is acquiring the first subband in the subband set corresponding to (current CQI value -1);

[0117] However, when the current subband is not the last subband in the subband set, the n...

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 field of communications, 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 perform frequency domain resource scheduling 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 the frequency domain resource scheduling of the UE is performed, it is generally realized by traversing and retrieving frequency domain resources. Assuming that the frequency domain resources are in units of subbands, each subband will have its corresponding channel quality indicator, that is, the CQI value, in the period. In the prior art, frequency domain resource scheduling is performed: first, according to the CQI value of the subband, the subbands are sorted in descending order of the CQI value, and then ...
