example 1

[0082] Example 1: If Figure 4 As shown in (a), the first time period may be the time period of the second reporting period, that is, the first time period is the time period T from the start position to the end position of period 1.

example 2

[0083] Example 2: If Figure 4 As shown in (b) in , the first time period can be the time period after the second reporting period is shifted forward by the first offset, that is, the first time period is from Figure 4 The time period T shown in (a) in (a) is moved forward as a whole by a time period after time T1.

example 3

[0084] Example 3: If Figure 5 As shown in (a), the first time period can be from the starting position in the reporting time unit in the second reporting period to the starting position in the reporting time unit (ie reporting time slot 2) in the first reporting period, that is The first time period is from the starting position of slot 2 in cycle 1 to the starting position of slot 2 in cycle 2 .

Abstract

The embodiment of the invention discloses a CSI processing method, a processing device and UE, relates to the technical field of communication and can improve the resource utilization rate in a CSI reporting process and save the waste of transmitting power of the UE. The method comprises the steps: obtaining first information, wherein the first information represents a decoding result of downlink transmission in a first time period or represents a measurement result of CSI in a first reporting period, and an end position of the first time period is at least not later than an initial position of a reporting resource of the CSI in the first reporting period; and determining a processing mode of the CSI in the first reporting period according to the first information. The embodiment of the invention is applied to the process of reporting the CSI by the UE.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a CSI processing method, a processing device, and a UE. Background technique [0002] In related technologies, a user equipment (user equipment, UE) may measure a channel state and report a measurement result, that is, channel state information (channel state information, CSI). [0003] Usually, the UE needs to periodically send periodic CSI (periodic CSI, P-CSI) and semi-persistent CSI (semi-persistent CSI, SP-CSI). Once the network device configures or activates the UE to report CSI periodically, the UE needs to The CSI is measured and reported within each reporting period. For example, in broadcast / multicast service transmission, the network device can configure the same CSI measurement information (such as CSI measurement reference signal and CSI measurement period) for multiple UEs. In each reporting period, after multiple UEs report CSI ...
