Description

Method, device, evolved node and computer readable storage medium for data packet splitting

Technical field

The present invention relates to, but is not limited to, the field of Carrier Aggregation (CA) in the LTE-A (Long Term Evolution-Advanced) system, and in particular, to a method, an apparatus, an evolved node, and a computer readable storage for data packet splitting. medium.

Background technique

LTE-A is a LTE (Long Term Evolution) subsequent evolution technology standard introduced by the 3GPP to meet the requirements of the International Telecommunication Union (ITU) proposed by the International Telecommunication Union (ITU). The LTE-A is the largest. Supports 100MHz system bandwidth, downlink peak rate exceeds 1Gbps, and uplink peak rate reaches 500Mbps. The LTE-A system design not only needs to meet the performance requirements, but also considers good backward compatibility with LTE to reduce the cost of carrier network upgrade.

In order to meet the peak rate requirement, LTE-A currently supports a maximum bandwidth of 100 MHz. However, it is difficult to find such a large bandwidth in the relevant available spectrum resources, and the large bandwidth brings great difficulty to the hardware design of the base station and the terminal. In addition, for spectrum resources dispersed in multiple frequency bands, a technology is needed to make full use of them. Based on the above considerations, LTE-A introduces the key technology of carrier aggregation.

The basic method of carrier aggregation is to divide a continuous spectrum or multiple discrete spectrum into multiple component carriers (CC). A user equipment (User Equipment, UE for short) that supports carrier aggregation can aggregate multiple component carriers and can simultaneously use PRB (Physical Resource Block) resources on all aggregated component carriers. The number of aggregated component carriers is up to 5, and each component carrier is up to 20 MHz; these component carriers can be close to or spaced apart.

In a carrier aggregation scenario, an Evolved Node B (eNB) aggregates two or more carriers and delivers a radio resource control (RRC) reconfiguration message to the UE, so that the UE can The aggregated carrier is used for transmission of services. The carrier that maintains the RRC connection with the UE is called a primary carrier component (PCC), and the corresponding cell is called a primary cell (Primary Cell, abbreviated as Pcell); The carrier is called a secondary carrier component (SCC), and the corresponding cell is called a secondary cell (Scell). For the UE supporting the CA, the primary carrier and the primary cell are always activated, the secondary carrier and the secondary cell are deactivated by default, and need to be activated before being used, and the secondary carrier and the secondary cell can pass the activated carrier and the cell. The activation is performed; likewise, the secondary carrier can also be deactivated by the activated carrier and the cell.

The PDCCH (Physical downlink control channel)/PDSCH (Physical downlink shared channel)/PUSCH (Physical uplink shared channel) of the PCC are all on the PCC, and the PDCCH of the SCC is used. /PDSCH/PUSCH may be on different CCs. The information of the uplink and downlink data packet size is only notified to the primary carrier, and the activated secondary carrier cannot receive the information of the data packet size. Therefore, in the scenario of such carrier aggregation, the related technical solutions still have the following needs to be solved. The problem: when the secondary carrier or the secondary cell is activated, the eNB needs to schedule and allocate resources of each carrier or cell, and when there is a data packet to be transmitted, it involves splitting the data packet between different carriers or cells. The problem.

At present, the research on packet splitting technology in this scenario is still blank.

Embodiment 1

A first embodiment of the present invention provides a method for splitting a data packet. As shown in FIG. 2, the method includes the following steps S201 to S203:

S201. When the UE accesses the PCC Pcell and the SCC or the Scell is also activated, the eNB performs the current ratio at a fixed ratio before determining the ratio of the current UE's rate on different cells/carriers in the previous time or time period. The data packets to be scheduled by the UE are split.

S202. The eNB determines a ratio of rates of current UEs on different cells/carriers in a previous time or time period.

S203. Split a data packet to be scheduled by the UE in a next time or time period according to a ratio of rates of current UEs on different cells/carriers in a previous time or a time period.

Wherein, the ratio of the rate may be a ratio of the corrected rate.

For the remaining resources that are not scheduled on the cell or carrier that are aggregated after the split, the eNB allocates the remaining resources to the UEs that are aggregated on the local cell or carrier.

The eNB determines the ratio of the average rate of the current UE on different cells/carriers in the previous time or time period, including steps S301-S303:

S301. The eNB first determines a scheduling capability of the UE on each cell/carrier, where the scheduling capability includes a channel quality of the UE, a scheduled scheduling resource, and a scheduling number.

S302. The eNB determines, according to the channel quality of the UE, the occupied scheduling resource, and the number of scheduling times, the rate of the UE on the cell/carrier.

S303. Determine a ratio of rates of UEs on different cells/carriers according to rates on respective cells/carriers.

If the channel quality of the UE scheduled on a certain cell/carrier is M and the occupied resource is N, the number of bits that the UE has recently scheduled is X according to the protocol, and the UE is combined with the UE in the cell/carrier. The number of times of scheduling Y in the last 1 s can be determined as the rate of the UE on the cell/carrier is Z=X*Y bit/s. Similarly, the rate of the UE on other cells/carriers can be determined. s, n represents the cell/carrier number. Finally, according to the rate of the UE on different cells/carriers Determine the rate ratio.

If the average channel quality of the UE in a period of time on a certain cell/carrier is M, and the average occupied resource is N, according to the protocol, the average number of bits per scheduling in the time period of the UE is X. The rate of the UE on the cell/carrier can be determined by combining the number of times Y scheduled by the UE in the previous time period on the cell/carrier. Here, the number of scheduling times Y in the time period needs to be converted into 1s. The number of times the UE is scheduled Y', and then determines that the average rate of the UE on the cell/carrier is Z=X*Y'bit/s. Similarly, the average rate of the UE on other cells/carriers Zn bit/s can be calculated, and n represents the cell/carrier number. Finally, the ratio of the average rates is determined according to the average rate of the UE on different cells/carriers.

If there are unscheduled remaining resources on a certain cell/carrier, these remaining resources are allocated to the scheduled UE.

The technical solution will be described below with reference to examples.

Example 1, the UE with the UE Index=10 initial access, activates two carriers, including steps 11 to 13:

Step 11: The eNB performs equalization splitting between the two carriers of the data packet to be scheduled by the UE.

Step 12: The eNB determines a ratio of an average rate of current UEs on different cells/carriers at a previous moment;

The channel quality of the Ue on the carrier 1 is 22, and the occupied resource is 32. According to the protocol, the number of bits that the UE has recently scheduled is 14688 bits, and the number of scheduling of the UE in the last 1 s on the carrier is 2, It can be determined that the rate of the UE on carrier 1 is 14688*2=29376 bit/s.

The channel quality of the Ue on the carrier 2 is 16 and the occupied resource is 40. According to the protocol, the number of bits that the UE has recently scheduled is 12216 bits, and the number of scheduling of the UE in the last 1 s on the carrier is 3, It can be determined that the rate of the UE on carrier 2 is 12216*3=36648 bits/s.

Then the ratio of the rate of the UE on carrier 1 and carrier 2 is 29376:36648=1:1.25.

Step 13: When the next data packet to be scheduled arrives, the eNB splits the data packet to be scheduled between carrier 1 and carrier 2 according to a ratio of 1:1.25.

Example 2: Initial access of the UE with UE Index=10, activation of two carriers, including steps 21 to 23:

Step 21: The eNB splits the data packet to be scheduled by the UE between two carriers.

Step 22: The eNB determines a ratio of an average rate of the current UE on different cells/carriers in the previous time period;

The average channel quality of the carrier 1 in the previous time period is 24, and the average occupied resource is 40. According to the protocol, the average number of bits per scheduling in the latest time period of the UE is 21384 bits, and the UE is in the The number of scheduling times in the latest time period on the carrier is 10, and the number of scheduling times in the time period is converted into the number of scheduling times of the UE in the 1s 10*2=20, and finally the average rate of the UE on the carrier is 21384*20. =427680bits/s.

The average channel quality of the carrier 2 in the previous time period is 10, and the average occupied resource is 20, according to the protocol, the average number of bits per scheduling in the latest time period of the UE is 3112 bits, and the UE is in the The number of scheduling times 30 in the latest time period on the carrier is calculated, and the number of scheduling times in the time period is converted into the number of scheduling times of the UE in the 1s 30*2=60, and finally the average rate of the UE on the carrier is 3112*60. =186720bits/s.

Then the ratio of the rate of the UE on carrier 1 and carrier 2 is 427680:186720=2.29:1.

Step 23: When the next scheduling period comes, the eNB splits the data packet to be scheduled between carrier 1 and carrier 2 according to a ratio of 1:1.25.

Example 3: The initial access of the UE with the UE Index=10 activates two carriers, including steps 31 to 34:

Step 31: The eNB enters the data packet to be scheduled by the UE between the two carriers by a ratio of 1:2. Line splitting;

Step 32: The eNB determines a ratio of an average rate of the current UE on different cells/carriers in the previous time period;

The average channel quality of the Ue in the most recent rate splitting period on the carrier 1 is 10, and the average occupied resource is 40. According to the protocol, the average number of bits per scheduling in the latest rate splitting period of the UE is 6200 bits. The number of scheduling times that the UE counts in the latest rate splitting period on the carrier is 10, and the number of scheduling times in the rate splitting period is converted into the number of scheduling times of the UE in the 1s 10*5=50, and finally the UE is obtained in the carrier. The average rate above is 6200*50=310000 bits/s.

The average channel quality of the Ue in the most recent rate splitting period on carrier 2 is 10, and the average occupied resource is 20, and there is an average of 10 RB resources remaining on the carrier in the statistical period. There are 5 scheduling UEs on the carrier in the statistical period. Then, the average occupied resource of the Ue is updated to be 20+10/5=22, and according to the protocol, the average number of bits per scheduling in the latest rate splitting period of the UE is 3496 bits, and the UE is the latest one on the carrier. The number of scheduling times in the rate splitting period is 40, and the number of scheduling times in the rate splitting period is converted into the number of scheduling times of the UE in the 1s 40*5=200, and finally the average rate of the UE on the carrier is 3496*200. =699200bits/s.

Then, the ratio of the rate of the UE on carrier 1 and carrier 2 is 310000:699200=1:2.26.

Step 33: The eNB corrects the ratio of the rates on the carrier 1 and the carrier 2, because in the initial state, the eNB splits the data packet to be scheduled by the UE between the two carriers by a ratio of 1:2, so after the correction The ratio of the carrier 1 to the rate on carrier 2 is (1 + 1): (2+2.26) = 2: 4.26;

In step 34, when the next scheduling period arrives, the eNB splits the data packet to be scheduled between carrier 1 and carrier 2 according to the ratio 2: 4.26 of the corrected average rate.
