Problems solved by technology

[0040] When the retransmitted uplink shared channel data and uplink control information are transmitted in the PUSCH of subframe i at the same time, the number of symbols after encoding the uplink control information is determined by the transport block size and bandwidth of the initial transmission of the uplink shared channel data (in subcarriers It is determined by information such as the unit) and other information; and from the above power control formula (that is, formula

Embodiment Construction

[0125] The basic idea of ​​the present invention is that when the uplink shared channel data and the uplink control information are transmitted on the PUSCH of subframe i at the same time, the terminal transmits the uplink shared channel according to the transmission power of the initial transmission of the uplink shared channel data and the transmission power of the uplink shared channel in subframe i The transmit power value of the data determines the number of symbols of the encoded uplink control signaling.

[0126] The present invention will be described in detail below with reference to the drawings and embodiments.

[0127] figure 1 It is a flowchart of a method for transmitting uplink control information in an embodiment of the present invention; figure 1 As shown, the method includes the following steps:

Abstract

The invention provides a method for transferring uplink control information. The method comprises the steps as follows: when uplink shared channel data and the uplink control information are required to be transferred in an uplink shared channel PUSCH of a subframe i simultaneously, a user terminal obtains the transmission power P<PUSCH> (init) of primarily transferred uplink shared channel data and the transmission power P<PUSCH> (i) of the uplink shared channel data transferred in the subframe i; the user terminal confirms the symbol quantity of the uplink control information after being coded in the subframe i according to the comparison relation between P<PUSCH> (init) and P<PUSCH> (i) and the size and the bandwidth of a transmission block when the uplink shared channel data is transferred primarily; the user terminal codes the uplink control information according to the symbol quantity of the uplink control information after being coded and transfers the coded uplink control information to a base station in the PUSCH of the subframe i.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for transmitting uplink control information and a method for calculating transmission parameters. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, the uplink physical channel mainly consists of channels such as PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel), PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel), and PUCCH is used for Transmit uplink control information. Wherein, the uplink control information includes ACK (Acknowledge, correct response) / NACK (Non-Acknowledge, wrong response) of uplink feedback, CQI (Channel Quality Indicator, channel quality indication), RI (Rank Indicator, rank indication information), PMI ( Precoding Matrix Indicator, precoding matrix indication) and other information. The PUSCH may transmit only uplink shared channel (Uplink Shared channel, UL-SCH...
