Embodiment Construction

[0091] figure 1 It is a schematic structural diagram of a mobile communication system to which the embodiments of the present application are applied. like figure 1 As shown, the mobile communication system includes a core network device 110, a radio access network device 120 and at least one terminal device (such as figure 1terminal device 130 and terminal device 140 in ). The terminal equipment is connected to the wireless access network equipment in a wireless manner, and the wireless access network equipment is connected with the core network equipment in a wireless or wired manner. The core network device and the radio access network device can be independent and different physical devices, or the functions of the core network device and the logical functions of the radio access network device can be integrated on the same physical device, or they can be one physical device. It integrates the functions of some core network equipment and some functions of the wireless a...

Abstract

The present application provides a wireless communication method, device, and system, wherein the method includes: receiving high-level signaling from a base station, which is used to indicate the downlink aggregation coefficient S, and the downlink aggregation coefficient S corresponds to S consecutive time transmission units, each time transmission The unit is used to repeatedly transmit the transmission block of the terminal; receiving physical layer signaling from the base station, used to schedule the transmission block of the terminal and including first indication information, the first indication information is used to indicate that part of the resources in the downlink control area can be used for transmission A transmission block of the terminal; determining a valid time of the first indication information, where the valid time is one or more time transmission units in S consecutive time transmission units. The wireless communication method, device and system provided in the present application can determine the use of some resources in the downlink control area by introducing the effective time of the first indication information, thereby reducing the probability of mutual interference between the transmission block and the downlink control information in the prior art, Thereby improving the performance of the communication system.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a wireless communication method, device, and system. Background technique [0002] The technical specification (TS) of the Third Generation Partnership Project (3GPP), such as the protocol of version 38.214v15.0.1, defines the scheduling method of slot aggregation (Slotaggregation). Wherein, the base station may send high-level signaling to the terminal, so that each time slot of a plurality of consecutive time slots in the downlink resource is used to repeatedly send the same transport block (TB). At the same time, in order to improve the utilization of downlink resources, the 3GPP protocol also defines that some Physical Downlink Control Channel (PDCCH) resources can be used to transmit Physical Downlink Shared Channel (Physical Downlink Shared Channel) resources to the terminal through physical layer signaling. , referred to as: PDSCH). [0003] Howev...
