Problems solved by technology

[0004] Since the terminal cannot quickly switch from one antenna to another, it will cause the problem of poor reliability of the signal transmission of the first symbol of the uplink time slot. If the network side continues to follow the conventional decoding method, the uplink time slot with poor reliability Decoding the signal of the first symbol will cause the decoding result to be unreliable

Embodiment Construction

[0085] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0086] Current 5G frequency bands can be used such as figure 1 In the frame structure shown, in the process of switching from downlink transmission to uplink transmission of the terminal, a special time slot needs to be spaced between the downlink time slot and the uplink time slot to ensure sufficient time for the special time slot. The terminal is ready for uplink transmission.

[0087] as if figure 1 The application scenario shown is an...

Abstract

The invention provides a terminal state reporting, configuring and switching method, a terminal and network side equipment, and belongs to the technical field of communication, and the terminal state reporting method applied to the network side equipment comprises the following steps: receiving first reporting information sent by the terminal, the first report information is used for representing that an antenna of the terminal for sending the last symbol of the special time slot is possibly different from an antenna of the terminal for sending the first symbol of the uplink time slot. According to the embodiment of the invention, the conflict condition of the antenna of the terminal can be reported, so that the condition that signals are transmitted on two continuous symbols and different antennas is avoided, the uplink transmission performance of a wireless system is improved, and particularly, the reliability of the first symbol of an uplink time slot can be improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a terminal state reporting, configuration and switching method, a terminal and a network side device. Background technique [0002] The frame structure used in the current 5G includes a downlink time slot, an uplink time slot and a special time slot in order, wherein the special time slot is used to provide a guard gap in the process of switching from downlink communication to uplink communication. Among them, the special time slot includes 14 symbols, of which the first 6 symbols are downlink symbols, the middle 4 symbols are used as guard intervals, and the last 4 symbols are uplink symbols, that is, the last uplink symbol in the special time slot and the first symbol of the uplink time slot. A symbol is adjacent. [0003] The current terminal often has 4 receiving antennas and 1 or 2 transmitting antennas, as well as the corresponding receiving radio fre...
