Description

Method and device for scheduling eMTC resources

Technical field

The embodiments of the present invention relate to the field of wireless communications technologies, and in particular, to a method and a device for scheduling eMTC resources.

Background technique

Machine to Machine (M2M) is a common application form in the Internet of Things (IOT). The 3rd Generation Partnership Project (3GPP) introduced Machine Type Communications (MTC) technology and Enhanced evolved Machine Type Communications (eMTC) technology.

The M2M service includes the smart meter reading service, the smart parking service, and the health monitoring service. The user equipment (UE) of the eMTC is deployed in indoor, corridor, basement and other weak coverage areas when the above services are implemented. The base station provides good coverage for the UE when the base station is added or less, and uses the coverage enhancement function of the eMTC to support the application of the M2M service. The 3GPP R13 protocol stipulates that the goal of eMTC coverage enhancement is to enhance 15dB with respect to Long Term Evolution (LTE) technology, mainly to enhance coverage by repeating techniques, that is, repeatedly transmitting the same data multiple times on the same channel. The 3GPP R13 protocol specifies that the maximum number of repetitions of the physical uplink control channel (PUCCH) is 32, and the maximum number of repetitions of the MTC physical downlink control channel (MPDCCH) is 256. The maximum number of repetitions of the Physical Downlink Shared Channel (PDSCH)/Physical Uplink Shared Channel (PUSCH) is 2048.

In the prior art, the evolved Node B (eNB) allocates a predetermined number of repetitions of PUSCH resources to the UE by using the Downlink Control Information (DCI) that is repeatedly sent by the MPDCCH, and the UE uses the PUSCH resources according to the PUSCH resources. Scheduled repetitions After the eNB successfully transmits the data, the UE cannot know that the UE needs to send the data sent to the eNB through the PUSCH for all predetermined repetition times indicated by the DCI. When the predetermined number of repetitions is large, if not Recovering the redundant PUSCH resources allocated to the UE causes waste of PUSCH resources. If the redundant PUSCH resources allocated to the UE are recovered, the UE does not know that the PUSCH resources originally allocated to itself are recovered and allocated to other users. The UE is caused to interfere with other users on the redundant PUSCH resources, and both of the above situations cause the power consumption of the UE to be large.

For example, the eNB allocates 16 times of PUSCH resources to the UE through the MPDCCH, and schedules 2 HARQ processes. The UE sends data to the eNB according to the number of repetitions of the PUSCH resources, as shown in FIG. When the eNB successfully receives the data for the 4th time and demodulates successfully, the remaining 12 remaining air interface resources are as shown in FIG. 2 .

In summary, after the eNB successfully receives the data sent by the UE, the UE continues to transmit the data through the PUSCH according to the predetermined number of repetitions, which may cause waste of air interface resources.
