Abstract:
Embodiments of the present invention provide a short range communications method, device, and system, and relate to the field of communications, so that a UE can distinguish, on a short range link, a radio bearer corresponding to transmission of data information. The method includes: establishing, by a benefited UE, a mapping between a short range bearer and a first radio bearer, where a mapping is performed between the short range bearer and a second radio bearer on a supporting UE side, and a mapping is performed between the first radio bearer and the second radio bearer on a base station side; and performing, by the benefited UE, data receiving and sending by using the mapping between the first radio bearer and the short range bearer.

Abstract:
A document presentation method and a user terminal are provided. The method includes selecting, by a user terminal from a plurality of documents on a screen according to a first click position of a user, a to-be-presented document that presents content, where all the documents on the screen are shielded and invisible to the user, identifying a selected input of the user, and adjusting a visible proportion of a shielded region of the to-be-presented document according to the identified selected input. In this way, the user terminal presents solely a document that needs to be shared when the user and a person with whom documents are shared watch a same computer screen together. The user terminal can correspondingly present a partial region of the to-be-presented document according to the selected input of the user, thereby avoiding excessive exposure of information when a shared document is browsed.
Abstract:
A method and apparatus for video resource management in a video conference is provided in embodiments of this invention. comprises: partitioning a display interface into a first display area, a second display area, a third display area; graphically representing a plurality of conference rooms participating in a video conference and presenting the plurality of graphical conference rooms participating in the video conference in the first display area; presenting a first graphical conference room comprising a first video resource, the first conference room being selected presented in the first display area; presenting the second graphical conference room in the third display area, the second conference rooms presented in the second display area. The embodiments of this invention may graphically represent video resources corresponding to screens or terminal video collecting apparatus in each conference room of a video conference, so that users can perceive situations in each conference room visually.
Abstract:
A user equipment (UE) communication method, a device, and a communications system are provided. A first UE sends a notification message to a cellular network access device, wherein the notification message indicates that the first UE requests to be a beacon device. The first UE receives, from the cellular network access device, a message indicating that the first UE is the beacon device. The first UE sends detection signal, wherein the detection signal is for a second UE to detect the detection signal.
Abstract:
Embodiments of the present invention provide a method and a device for transmitting downlink data in multiple UEs cooperative communication. A base station selects a benefitted user equipment UE, where the benefitted UE and a supporting UE are UEs in a closed cooperative group, each data radio bearer of each UE in the cooperative group corresponds to a logical channel identifier LCID, and the LCID is unique in the cooperative group; the base station generates a media access control packet data unit MAC PDU, where the MAC PDU comprises data to be sent by a data radio bearer of the benefitted UE, and a LCID corresponding to the data radio bearer, and the base station sends the MAC PDU to the supporting UE. The above solutions achieve a method of multiple UEs cooperative communication for synthesizing on the MAC layer.
Abstract:
A data sending method is provided. Media access control MAC payloads corresponding to a plurality of user equipment (UEs) are encapsulated in one MAC packet data unit PDU, where the MAC PDU includes a header, the MAC payloads and identification information of each UE in the plurality of UEs; and the header includes a plurality of subheaders, the plurality of subheaders is subheaders respectively corresponding to a MAC payload corresponding to each UE in the plurality of UEs, the MAC payload corresponding to each UE includes a MAC control element CE and/or a MAC service data unit SDU, and the identification information is used for identifying each UE. The MAC PDU is sent. Correspondingly, a data receiving method and apparatus are also provided. In the foregoing solutions, transmission of a MAC PDU during multi-user cooperated communication is implemented.
Abstract:
The present invention discloses a multiple users cooperative communication (MUCC) method and system. The main idea of the present invention is as follows: through multiple users cooperative communication between APs, data to be sent to a UE by an eNB may be sent to a support AP at first, and then the support AP sends the data to the UE; and when the support AP is in a poor network environment, the eNB may send the data to other APs near the support AP, and finally forward the data to the support AP through one or more times of forwarding between other APs. The present invention has a multiuser diversity gain without increasing the complexity and power consumption of the UE; furthermore, a laying cost of wired backhaul can be reduced and reliability and transmission efficiency of MUCC can be improved.
