Embodiment Construction

[0049] Those skilled in the art will recognize and understand that the details of the described examples are merely illustrative of some examples and that the teachings herein apply to various alternatives.

[0050] image 3 A schematic diagram showing a cellular network formed by three base stations (eg, eNB base stations or gNB base stations according to a particular cellular standard and technology) is shown. Typically, each base station is deployed by a cellular network operator to provide geographic coverage for multiple UEs in the area. Multiple base stations form a wireless area network (Radio Area Network, RAN). Each base station provides wireless coverage for multiple user equipments in its area or cell. Multiple base stations are connected to each other through the X2 interface and connected to the core network through the S1 interface. It will be appreciated that this application presents only fundamental details to illustrate key features of cellular networks. ...

Abstract

Methods and systems for management of uplink HARQ processes where fewer than a defined number of repetitions of uplink data are transmitted on configured grant resources. The applied HARQ processes may be varied dependent on the number of repetitions transmitted and dependent on the reception status at the base station.

Description

technical field [0001] The present invention relates to a transmission strategy for uplink configuration authorization transmission, in particular to a Hybrid Automatic Repeat Request (HARQ) strategy for this type of transmission. Background technique [0002] Wireless communication systems, such as third-generation (third-generation, 3G) mobile communication standards and technologies are well known. Such third generation mobile communication standards and technologies are developed by the Third Generation Partnership Project (Third Generation Partnership Project, 3GPP). The third generation of wireless communication has been developed to support macro cell phone communication. Communication systems and networks have evolved towards broadband mobile systems. [0003] In a cellular wireless communication system, a user equipment (User Equipment, UE) is connected to a radio access network (Radio Access Network, RAN) through a wireless link. The radio access network (RAN) i...
