Method for transmitting control information, user equipment and base station

摘要

Embodiments of the present application provide a method for transmitting control information, a user equipment and a base station. The method includes: acquiring a resource index of a physical uplink control channel PUCCH; acquiring a sequence index of an orthogonal sequence of the PUCCH according to the resource index, and acquiring the orthogonal sequence according to the sequence index; acquiring a cyclic shift of a reference signal of the PUCCH according to the sequence index; and transmitting the UCI to the base station on the PUCCH according to the orthogonal sequence and the cyclic shift. In the embodiments of the present application, a cyclic shift of a reference signal of a PUCCH channel for transmitting UCI is acquired according to a sequence index, and the UCI is transmitted on the PUCCH according to the cyclic shift and a corresponding orthogonal sequence, which can enhance transmission performance of the UCI.

1. A method for transmitting control information, comprising:
acquiring a resource index of a physical uplink control channel (PUCCH), wherein the PUCCH is used for transmitting uplink control information (UCI); acquiring a sequence index of an orthogonal sequence of the PUCCH according to the acquired resource index; acquiring the orthogonal sequence according to the acquired sequence index; acquiring a cyclic shift of a reference signal of the PUCCH according to the acquired sequence index; and transmitting the UCI to a base station on the PUCCH according to the acquired orthogonal sequence and the acquired cyclic shift, wherein
the acquiring a cyclic shift of a reference signal of the PUCCH according to the acquired sequence index comprises:determining, if the UCI only comprises periodic channel state information (CSI), that the cyclic shift is a first cyclic shift corresponding to the acquired sequence index, anddetermining, if the UCI comprises periodic CSI and hybrid automatic repeat request-acknowledgment (HARQ-ACK) or the UCI comprises periodic CSI, HARQ-ACK and a scheduling request (SR), that the cyclic shift is a second cyclic shift corresponding to the acquired sequence index.
