Problems solved by technology

The final result is that under the parameters defined in the original specification version 8 / 9 / 10 (TTIbundling=4, RTT=16, feedback cycle=N+4), only one HAQR process can be configured in one RTT, and more than one processes are not working
Clearly, such resource efficiency is unacceptable and must be improved

Embodiment Construction

[0040] In the following detailed description of the preferred embodiments, reference will be made to the accompanying drawings which form a part hereof. The accompanying drawings show, by way of example, specific embodiments in which the invention can be practiced. The illustrated embodiments are not intended to be exhaustive of all embodiments in accordance with the invention. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. Accordingly, the following detailed description is not limiting, and the scope of the invention is defined by the appended claims.

[0041]First, according to the foregoing, in the 3GPP specification version 8 / 9 / 10, it is stipulated that in the case where TTIbundling is configured, the number of HARQ processes configured on the UE is 4. However, because the low-cost MTCUE works in the HDFDD mode, the corresponding specification parameter...

Abstract

The invention discloses a method of receiving a hybrid automatic repeat request response on user equipment in an LTE wireless communication system. The user equipment works in a half-duplex frequency division duplex mode. The method is characterized in that the user equipment is configured with transmit time interval bundling and two hybrid automatic repeat request response processing processes.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to the technical field of wireless communication. Background technique [0002] In the field of wireless communication, research on Machine Type Communication (MTC) is receiving increasing attention. In particular, how to integrate the MTC device into the standard wireless communication network architecture and make it interoperable with various devices in the existing communication network has become a hot development direction. The 3GPP standardization organization recently proposed a project aimed at combining low-cost MTC user equipment (UE for short) with an LTE network. [0003] In this project, a problem that needs to be solved is how to cooperate with LTE network equipment in full duplex (FD) mode when the low-cost MTCUE is in the half-duplex (HalfDuplex for short HD) working mode. Among them, the consideration of low-cost MTCUE adopting HD working mode is ma...
