Embodiment Construction

[0043] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. It should be understood that the embodiments described below are only used to illustrate and explain the present application, and are not intended to limit the present application.

[0044] In the actual application of the TDD LTE system, there may be differences in the interference on multiple uplink symbols. For example, under an atmospheric duct (Atmosphere Duct), the interference on the uplink symbols decreases sequentially from the UpPTS. For another example, when cross-slot interference occurs due to some reason, the interference on multiple uplink symbols is also different. Similarly, in the 5G communication system, there is also the problem that the difference in inter-symbol interference leads to the loss of overall uplink performance.

[0045] The present application provides a communication method and device, which introduces a symbol ad...

Abstract

The present application discloses a communication method and device. The communication method includes: the base station sends symbol configuration information; wherein the symbol configuration information is used to indicate at least one of the following: uplink symbols that cannot be used for uplink transmission, and symbols that can be used for uplink transmission up symbol.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication method and device. Background technique [0002] In the LTE (Long Term Evolution, Long Term Evolution) system, the frame structure is fixed, and the symbols that can be used for multiple uplink channel transmissions are also fixed. For example, if figure 1 As shown, the frame structure of the TDD (Time Division Duplex, Time Division Duplex) LTE system is configured as follows: under the TDD configuration 2, the symbols that can be used for uplink transmission include uplink pilot time slot (UpPTS, Uplink Pilot Time Slot), sub Frame (Subframe) #2 and Subframe #7, where 1 to 2 uplink transmission symbols can be configured on the UpPTS, 12 symbols (Extended CyclicPrefix) or 14 symbols (Normal Prefix (Normal Cyclic Prefix)). [0003] In a 5G (Fifth Generation, fifth generation mobile communication technology) communication system, the frame structure is also fixed...
