INFORMATION TRANSMISSION METHOD AND DEVICE IN MULTI-ANTENNA PORT SCENARIO

摘要

Disclosed are an information transmission method and device in a multi-antenna port scenario. By applying the technical solution in the embodiments of the present invention, for terminal equipment with multi-antenna port transmission, a pre-coding vector of an uplink control channel at a multi-antenna port is obtained according to the configuration information sent by a base station, and the corresponding data after being pre-coded by the pre-coding vector is sent using the same PUCCH resource at each antenna port, and therefore, by configuring a pre-coding vector applied to a multi-antenna port in each timeslot rationally, the performance gain of the PUCCH transmit diversity is ensured on the basis of reducing the overhead of the PUCCH resource as far as possible.
