Embodiment Construction

[0028] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0029] The methods discussed later herein, some of which are illustrated by flowcharts, can be implemented by hardware, software, firmware, middleware, microcode, hardware description languages, or any combination thereof. When implemented in software, firmware, middleware or microcode, the program code or code segments to perform the necessary tasks may be sto...

Abstract

The invention aims at providing (an) ACK / NACK report method, equipment and system for a Cat-M mechanism. On the basis of downlink data, the user equipment back feeds an ACK / NACK message to an eNB in aPUSCH, and when the number of resource elements occupied by the ACK / NACK message in the PUSCH, the number of OFDM symbols of protection interval is eliminated. Thus, the PUSCH data code rate of the UE can be reduced effectively, and the decoding performance of the eNB in the PUSCH is improved at the same time.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a technology for ACK / NACK reporting of Cat-M mechanism. Background technique [0002] In order to reduce the data transmission of Internet of Things (IoT, Internet of Things) devices via the LTE network, Cat-M (Category Machine-Type, classified machine type) was introduced in 3GPP LTE Release 13 (Release 13). Cat-M UE (User Equipment, user equipment) aims at low complexity and low power consumption. Cat-M UE can only be used for narrowband, that is, Cat-M DL (Downlink, downlink) and UL (Uplink, uplink) physical channels can occupy up to 6 resource blocks (RB, Resource Block). For UL, a guard period is created for Tx-to-Tx frequency retuning between two consecutive subframes. This guard interval is one or more OFDM symbols in number. These OFDM symbols cannot be used for PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) data transmission. [0...
