    Abstract: A method for transmission and reception in parallel on dual channels includes, when detecting that a first channel is occupied by CSMA contention, determining, by an AP, first transmission duration of a first channel data packet. The method additionally includes determining, by means of CCA detection, that a second channel is idle, where the second channel is used to transmit a second channel data packet whose transmission direction is opposite to a transmission direction of the first channel. The method additionally includes determining, by using the first transmission duration, second transmission duration for transmitting the second channel data packet, and transmitting the second channel data packet according to the second transmission duration, where an end time of transmission of the second channel data is not later than an end time of transmission of the first channel data.

    Abstract: The present invention discloses a method for transmitting data between a baseband processing unit BBU and a remote radio unit RRU, and a data transmission apparatus. The RRU selects partial data in received data, and sends the partial data to the BBU by using a common public interface CPRI; or the BBU performs only channel coding processing or only channel coding processing and constellation mapping processing on the data, and sends processed data to the RRU. Then the RRU performs constellation mapping processing, multiple-antenna multiple-input multiple-output MIMO coding processing, and orthogonal frequency division multiplexing OFDM symbol generation processing on the data, or the RRU performs MIMO coding processing and OFDM symbol generation processing on the data. That is, steps in which data redundancy is added are executed by the RRU.

    Abstract translation: 本发明公开了一种在基带处理单元BBU和远程无线单元RRU之间发送数据的方法以及数据发送装置。 RRU在接收到的数据中选择部分数据,并使用通用公共接口CPRI将部分数据发送到BBU; 或者BBU仅对数据执行信道编码处理或仅进行信道编码处理和星座映射处理,并将处理的数据发送到RRU。 然后,RRU对该数据执行星座映射处理,多天线多输入多输出MIMO编码处理和正交频分复用OFDM符号生成处理,或者RRU对该数据进行MIMO编码处理和OFDM符号生成处理。 也就是说,RRU执行添加数据冗余的步骤。

    Abstract: This application relates to a resource selection method and a first terminal. The method includes: before determining a first transmission resource used to transmit a first transport block, a first terminal determines first duration required by the first terminal to perform first LBT, and determines an unavailable resource in a resource selection window based on the first duration; and/or determines second duration required by a second terminal to perform second LBT, and determines an unavailable resource in the resource selection window based on the second duration. The first terminal selects the first transmission resource based on at least one of the first unavailable resource or the second unavailable resource.
