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.
在现有技术中,演进型基站(evolved Node B,eNB)通过MPDCCH重复下发的下行控制信息(Downlink Control Information,DCI)给UE分配预定的重复次数的PUSCH资源,UE通过所述PUSCH资源按照预定的重复次数
发送数据至eNB,eNB成功接收数据后,UE不能获知,UE需要把DCI指示的所有预定的重复次数的通过PUSCH发送给eNB的数据发送完,当所述预定的重复次数很大时,若不回收分配给UE的多余的PUSCH资源,则造成了PUSCH资源浪费,若回收了分配给UE的多余的PUSCH资源,而UE并不知道原来分配给自身的PUSCH资源被回收并分配给其它用户,可能导致所述UE在多余的PUSCH资源上干扰其他用户,并且上述两种情况都会造成所述UE的功率消耗大。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.
举例说明:eNB通过MPDCCH重复下发4次DCI给UE分配16次的PUSCH资源,调度2个HARQ进程,UE通过所述PUSCH资源按照16次的重复次数发送数据至eNB,如图1所示,当eNB在第4次成功接收到数据,解调成功后,剩余的12次多余的空口资源,如图2所示。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 .
综上所述,当eNB成功接收UE发送的数据后,UE继续按照预定的重复次数通过PUSCH传输该数据,会造成空口资源浪费。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.
