A method includes: determining, according to a measurement report of agent UE and a measurement report of UE in a UE group that are sent by the agent UE, whether the agent UE and the UE in the UE group need to be handed over; when the agent UE and at least one piece of UE in the UE group need to be handed over, sending a handover request message to a T-eNB; receiving a handover configuration message sent by the T-eNB and sending the handover configuration message to the agent UE; and receiving a context release message sent by the T-eNB, and releasing context resources of the agent UE and the to-be-handed-over UE.

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.

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.

The present invention is applicable to the field of communications and provides an MBMS technology-based emergency communication method and apparatus. The method includes: receiving information for establishing air interface bearer, where the information is sent by a terrestrial radio access network E-UTRAN/UTRAN, the information indicates that the air interface bearer has a highest scheduling priority and is not stopped and instructs a user equipment to monitor the air interface bearer in real time; establishing the air interface bearer with the E-UTRAN/UTRAN, and monitoring the air interface bearer in real time; and receiving emergency information that is sent by the E-UTRAN/UTRAN from the air interface bearer. Because the user equipment monitors the MBMS communication channel in real time, a second-level delay of MBMS communication is eliminated, so that MBMS technology-based communication meets a delay requirement of emergency communication.

A data sending method is provided. Media access control MAC payloads corresponding to a plurality of receiving devices are encapsulated in one MAC packet data unit (PDU), where the MAC PDU includes a header, the MAC payloads and identification information of each receiving device in the plurality of receiving devices; and the header includes a plurality of subheaders, the plurality of subheaders is subheaders respectively corresponding to a MAC payload corresponding to each receiving device, the MAC payload corresponding to each receiving device includes a MAC control element (CE) and/or a MAC service data unit (SDU), and the identification information is used for identifying each receiving device. The MAC PDU is sent. In the foregoing solutions, transmission of a MAC PDU during multi-user cooperated communication is implemented.
摘要:
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.

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.
