Description

User equipment and method and device for transmitting periodic CSI

Technical field

The present invention relates to the field of information technology, and in particular, to a user equipment and a method and apparatus for transmitting periodic CSI.

Background technique

The state of the wireless channel is usually changed. In order to better adapt to the change of the channel state, the user equipment UE can report the channel state information (English name: CSI) to the base station, so that the base station can be based on the user. The CSI reported by the device determines the modulation and coding scheme (English name: modulation and Coding Scheme, English abbreviation: MCS). The CSI reference resource is a CSI reference resource. In the time domain, the CSI reference resource is defined as a single downlink subframe or special. The subframe nn _{CQI_ref} , so the user equipment needs to determine the reported uplink subframe and the downlink subframe for measuring CSI, and the CSI has been sent.

At present, a method for transmitting a periodic CSI includes a channel quality information (English full name: Channel Quality Indicator, English abbreviation: CQI), a precoding matrix indicator (English full name: Precoding Matrix Indicator, English abbreviation: PMI), and a precoding type. Indication (English full name: Precoding Type Indicator, English abbreviation: PTI) and rank indication (English full name: Rand Indication, English abbreviation: RI), user equipment through formula

Determine the uplink subframe and the downlink measurement subframe for reporting the CQI or PMI, and the user equipment passes the formula.

The uplink subframe and the downlink measurement subframe of the RI are determined, that is, the user equipment acquires the CSI through the downlink measurement subframe, and sends the CSI by reporting the uplink subframe of the CSI.

However, by using the above two formulas, the uplink reporting subframe and the downlink measurement subframe are determined to transmit CSI. Since the TTI lengths of the uplink and downlink subframes are the same and are 1 ms, if the uplink and downlink are not 1 ms, the transmission duration is different. If the length of the transmission is long, the uplink subframe and the downlink measurement subframe that report the CSI cannot be determined by using the above two formulas. As a result, the CSI cannot be sent.
