Embodiment 1

[0031] Embodiment 1: Sending the same unicast control signaling to the sending terminal and receiving terminal of each secondary link, and assigning an identifier to the secondary link for scrambling and descrambling of the unicast control signaling; Further, the unicast control signaling can indicate the transmission direction of the secondary link data signal.

Embodiment 2

[0032] Embodiment 2: Send unicast control signaling to the sending terminal and the receiving terminal respectively, and add information of the receiving terminal and the sending terminal to the unicast control signaling respectively.

Embodiment 3

[0033]Embodiment 3: Send unicast control signaling to the sending terminal and receiving terminal respectively, and use different unicast control signaling for different receiving terminals and receiving terminal unicast control signaling for different sending terminals The identifier is scrambled and descrambled.

[0034] The technical solutions provided by various embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0035] figure 2 It is an embodiment in which the base station sends the same unicast control signaling to the sending terminal and the receiving terminal, where the unicast identifier corresponds to the connection between the sending terminal and the receiving terminal.

[0036] The base station sends unicast control signaling to two controlled terminals (sending terminal and receiving terminal) through the first type of air interface; the unicast control signaling includes resource informatio...

Abstract

The present application discloses a terminal direct unicast control method for mobile communication to solve the problem that the current control signaling cannot realize unicast communication. The base station sends unicast control signaling to at least one controlled terminal through the first type of air interface; the unicast control signaling includes resource information and signal format information occupied by the secondary link data signal, and also includes unicast identification information; The controlled terminal receives the unicast control signaling, determines a communication object according to the unicast identification information, and sends or receives the secondary link data signal according to the resource and signal format; the first type of air interface is An air interface between a base station and a terminal; the second type of air interface is an air interface between terminals; the secondary link data signal is transmitted through the second type of air interface. Compared with the prior art solution, the solution of the present invention can realize reliable unicast transmission, has a simple solution and high security.

Description

technical field [0001] The present application relates to the field of mobile communication, in particular to a communication signaling control method for terminal direct communication to realize unicast. Background technique [0002] Direct-to-device (D2D) technology for mobile communication can make full use of direct communication between terminals in close proximity to replace communication with base stations and reduce network load. It has been widely studied in many standardization organizations, including Bluetooth, LTED2D, IEEE 802.11p, LTE V2X, etc. At present, the D2D / V2X technology in the 4G standard only implements the broadcast and multicast modes, but does not implement the unicast mode. However, for the development of mobile communications in the future 5G stage, the broadcast and multicast modes can no longer meet the needs. For example, applications such as wearable devices and the Internet of Things require direct terminal transmission between specific de...
