說明書
In another embodiment of the present invention, if the preset condition is that the first subframe is a first subframe or a sixth subframe in a radio frame, and the first subframe is located in a DMTC of the carrier on which the first cell is located, the data transmission characteristic is that the downlink data transmission length of the first subframe is an element included in a first time set. That is, a preset rule is: When the first subframe is a first subframe or a sixth subframe in a radio frame, and the first subframe is located in the DMTC of the carrier on which the first cell is located, the downlink data transmission length of the first subframe is the element included in the first time set.
In an example, when the downlink data transmission configuration of the first cell is a normal cyclic prefix, the element included in the first time set is only: one or more of three OFDM symbols, six OFDM symbols, or 12 OFDM symbols, and the first time set does not include another element except the one or more of three OFDM symbols, six OFDM symbols, or 12 OFDM symbols. For example, if the element included in the first time set is: three OFDM symbols and six OFDM symbols, the first time set includes only the two elements, and does not include another element. When the downlink data transmission configuration of the first cell is an extended cyclic prefix, the element included in the first time set is: one or more of three OFDM symbols, five OFDM symbols, or 10 OFDM symbols, and the first time set does not include another element except the one or more of three OFDM symbols, five OFDM symbols, or 10 OFDM symbols. For example, if the element included in the first time set is: three OFDM symbols and five OFDM symbols, the first time set includes only the two elements, and does not include another element.
