Embodiment Construction

[0068] The application will be described in further detail below in conjunction with the accompanying drawings.

[0069]Various aspects are described herein in connection with terminals and / or base stations. A terminal refers to a device that provides voice and / or data connectivity to a user, including a wireless terminal or a wired terminal. The wireless terminal may be a handheld device with a wireless connection function, or other processing device connected to a wireless modem, and a mobile terminal that communicates with one or more core networks via a wireless access network. Wireless terminals may be, for example, mobile telephones (or "cellular" telephones) and computers with mobile terminals. As another example, the wireless terminal may also be a portable, pocket, hand-held, computer built-in or vehicle-mounted mobile device. For another example, the wireless terminal may be a mobile station (mobile station), an access point (access point), or a part of a user equi...

Abstract

The invention discloses a CSI reporting method and a terminal device. The method comprises the steps that the terminal device receives M CSI reporting configurations issued by a base station, configurations of first CSI-RS resources associated with each CSI reporting configuration, and first signaling; For a first CSI-RS resource associated with any CSI reporting configuration, the terminal devicedetermines a second CSI-RS resource corresponding to the CSI reporting configuration according to the first signaling; The terminal device configures a corresponding first CSI-according to each CSI report, determines the priority order of the M CSI reporting configurations by using the RS resources and the second CSI-RS resources; The terminal device sends a CSI report to the base station according to the priority order; The method is used for solving the problem that a CSI report reported by current terminal equipment is incomplete, downlink resource scheduling of the UE is limited by a basestation, and the utilization rate of downlink resources is reduced.

Description

technical field [0001] The present application relates to the field of information technology, and in particular to a method for reporting CSI and a terminal device. Background technique [0002] Wireless channel conditions are usually constantly changing, for example, UE moves from an area with good channel conditions to an area with poor channel conditions; or UE moves on a street with tall buildings on both sides, then the street along the direction of signal propagation The signal will increase, while on the street perpendicular to the direction of propagation the signal will decrease. In order to better adapt to changes in the wireless channel, the base station sends a channel state information reference signal (channel state information-RS, CSI-RS) to the UE, and each CSI-RS will be carried on a specific time-frequency resource, that is, CSI-RS RS resource (CSI-RS resource). The UE can report the channel state to the base station through channel state information (Ch...
