Problems solved by technology

[0003] When scheduling resources, for the UE, it is necessary to first detect the Physical Downlink Control Channel (PDCCH) to obtain the uplink scheduling information carried by the eNB in ​​the PDCCH, and analyze the position of the uplink resources used for transmitting uplink data. And the transmission format used to transmit uplink data, so as to send uplink data, and the complexity of detecting PDCCH is very high, which is not conducive to UE power saving

Abstract

In the technical field of communications, a periodic service communication method, an eNB and a UE are disclosed to reduce the complexity of resource scheduling and achieve energy saving. A periodic service communication method comprises: sending a periodic uplink resource scheduling parameter to a UE, so that the UE determines, according to the periodic uplink resource scheduling parameter, an uplink resource and a transmission format for transmitting uplink data, the periodic uplink resource scheduling parameter comprising positions of the uplink resource in time domain and frequency domain dimensions and an uplink data transmission format; and receiving uplink data sent by the UE.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a communication method for periodic services, eNB and UE. Background technique [0002] The long term evolution (Long Term Evolution, LTE) standard adopts a scheduling mechanism, and an evolved base station (Evolved Node Base-station, eNB) performs unified resource management and control. A business scenario is cyclical, and the size of the data packet is fixed, and it is mainly uplink data. For example: meter reading, periodic monitoring, status reporting, etc. For the above periodic service scenario, after the user equipment (UE) initially accesses the network, it remains in the connected state, so as to save signaling overhead such as establishment of a bearer during each random access. [0003] When scheduling resources, for the UE, it is necessary to first detect the Physical Downlink Control Channel (PDCCH) to obtain the uplink scheduling information carrie...
