Abstract:
1. A method for transmitting channel quality indicator information of multiple user equipments, the method comprising: at least two user equipments transmitting their respective channel quality indicator information on the same time-frequency resource comprising at least one frequency-domain unit in the frequency domain and at least two sets of data time-domain units in the time domain, wherein each set of data time-domain unit comprises at least two data time-domain units, and the channel quality indicator information of different user equipments is transmitted on at least one set of data time-domain units in a time-domain code division multiple access mode; and wherein transmitting the channel quality indicator information of different user equipments in the time-domain code division multiple access mode on at least one set of data time-domain units comprises: each of the user equipments generating a corresponding number of channel quality indicator symbols according to an amount of the channel quality indicator information of the user equipment to be transmitted on the time-frequency resource, wherein each channel quality indicator symbol corresponds to at least one set of data time-domain units, presetting a time-domain frequency-spreading code comprising the same number of elements as the number of data time-domain units in each set of data time-domain units, wherein each element in the time-domain frequency-spreading code corresponds to one of the data time-domain units in the corresponding set of data time-domain units, and multiplying each channel quality indicator symbol by the corresponding element in the time-domain frequency-spreading code and then transmitting the product in the corresponding data time-domain unit.
