Abstract: A display includes a polygonal display region and a plurality of non-display portions. The non-display portions are coupled to side edges of the display region in a one-to-one correspondence. At least two of the non-display portions are bent to a back side of the display region. When the non-display portions bent to the back side include adjacent non-display portions, there is an opening between two adjacent non-display portions.

Abstract: The present invention discloses a data sending method and a communications device. The method includes: sensing, by a communications device, a carrier located in a first unlicensed frequency band, where the first unlicensed frequency band includes at least one carrier; and sending, by the communications device, data on a carrier whose channel state is sensed to be idle. The communications device senses a first carrier in the first unlicensed frequency band, and sends the data on the first carrier that is successfully sensed to be idle. Another communications device may also sense in the first unlicensed frequency band, and send data in the first unlicensed frequency band when sensing successfully. Therefore, users of different services may fairly contend and coexist in an unlicensed frequency band.

Abstract: A communication system and method are provided. The communication system includes a master base station, a slave base station and a remote radio unit (RRU); where a cell controlled by the slave base station is included in cells controlled by the master base station. The master base station is configured to receive downlink data and send the downlink data to the slave base station; and the slave base station corresponds to a transmission channel identifier of the downlink data. The slave base station is configured to receive the downlink data sent by the master base station, convert the downlink data into air interface downlink vector data, and send the air interface downlink vector data to the RRU. The RRU is configured to convert the air interface downlink vector data into analog data and send the analog data to a user equipment, thereby realizing data transmission.

Abstract: This application provides for data transmission between first and second network devices. The first network device requests information from the second network device and in return receives grant information from the second network device. The grant information includes at least a first sequence number that is used by the first network device to determine a first credit limit, where the first credit limit is an amount of data allowed to be sent by the first network device in a packet-distributed load sharing manner. The first network device sends data to the second network device based on the first credit limit. Second and third sequence numbers are also described.
