Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The techniques described herein may be used in various communication systems, such as current 2G, 3G communication systems and next generation communication systems, for example, Global System for Mobile communications (GSM) systems, Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Wideband Code Division Multiple Access (WCDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, General purpose FDMA systems, Packet radio service (GPRS) systems, and other such communication systems.
Various aspects are described herein in connection with a terminal and/or a base station node.
A user equipment, which may be a wireless terminal or a wired terminal, may refer to a device that provides voice and/or data connectivity to a user, a handheld device having wireless connection capability, or other processing device connected to a wireless modem. A wireless terminal, which may be a mobile terminal such as a mobile phone (or "cellular" phone) and a computer having a mobile terminal, for example, a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device, may communicate with one or more core networks via a Radio Access Network (RAN). For example, Personal Communication Service (PCS) phones, cordless phones, SIP phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. A wireless Terminal may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), an Access Point (Access Point), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), and a User Equipment (User Equipment).
A base station (e.g., access point) can refer to a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminals. The base station may be configured to convert the received air frame and the IP packet into each other, and may be used as a router between the wireless terminal and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) network. The base station may also coordinate management of attributes for the air interface. For example, the Base Station may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, or an evolved Node B (NodeB) in LTE, which is not limited in this application.
Additionally, the terms "system" and "network" are often used interchangeably herein.
As is well known, as shown in fig. 1, the D2D technology is an end-to-end direct communication technology, which not only can share heavy network load of a mobile communication network and offload cellular service, but also can improve the spectrum efficiency of the mobile communication network and enable the mobile communication network to obtain higher throughput performance and lower transmission delay based on the natural advantages of short-range communication, and therefore, the D2D technology has become a major topic of research by those skilled in the art.
However, in the existing D2D technology, when the UE uses a broadcast or multicast mode for data transmission, only a single-hop transmission method is supported, and this transmission method results in a very limited transmission range of the data packet sent by the sending end, thereby greatly limiting the application range and application scenario of the D2D technology. For example, in a mobile local advertisement (english: mobile advertisement) scenario, a retailer needs to broadcast its own discount information through a user equipment using D2D technology, but because the existing D2D technology only supports a single-hop transmission method, the coverage of the broadcast is only one hop, that is, the discount information can only be broadcast from a source node to other nodes, and other nodes receiving the discount information do not forward any more, such a transmission method makes the broadcast range of the advertisement extremely limited, thereby affecting the advertisement effect. For another example, in a social application (english: social application) scenario, the UE broadcasts its own friend making requirement through the D2D application, and in this case, the existing D2D technology only supports a single-hop transmission method, so that the broadcast range is limited, and the probability of finding a friend with the same interest is reduced.
The data transmission method provided by the invention can be used for well solving the problems. In addition, in order to facilitate understanding of those skilled in the art, the present invention will be described in detail with reference to the following embodiments.
An embodiment of the present invention provides a data transmission method, as shown in fig. 2, the method may include:
101. the network equipment sends indication information to the UE, wherein the indication information is used for indicating the maximum hop count adopted when the UE adopts a broadcast or multicast mode for data transmission.

In this embodiment of the present invention, further, in a second possible implementation manner, step 101 may specifically include: the network device sends the indication information to the UE through a dedicated Radio Resource Control (RRC) message.

In this embodiment of the present invention, further, in a fourth possible implementation manner, step 101 may specifically include: the network equipment sends the indication information to the UE through the management message.

201. and the UE receives indication information sent by the network equipment, wherein the indication information is used for indicating the maximum hop count adopted when the UE adopts a broadcast or multicast mode for data transmission.
202. And the UE configures the hop count for data transmission in a broadcast or multicast mode according to the indication information.
203. And the UE transmits data by adopting a broadcast or multicast mode according to the hop count.
According to the data transmission method provided by the embodiment of the invention, the UE receives the indication information which is sent by the network equipment and used for indicating the maximum hop count adopted when the UE adopts the broadcast or multicast mode for data transmission, the hop count is configured according to the indication information, and then the data transmission is carried out by adopting the broadcast or multicast mode according to the configured hop count, so that after the sending end adopts the broadcast or multicast mode to transmit the data packet to the receiving end, the receiving end can continue to forward the received data packet, and the problem that the transmission range of the data packet sent by the sending end is very limited because the UE adopting the D2D technology adopts a single-hop transmission mode for data transmission is solved.

Another embodiment of the present invention provides a data transmission method, as shown in fig. 4, the method may include:
301. the network equipment sends indication information to the UE, wherein the indication information is used for indicating the maximum hop count adopted when the UE adopts a broadcast or multicast mode for data transmission.
In order to expand the coverage of the UE for data transmission and avoid broadcast or multicast flooding, the network device may send, to the UE, indication information indicating a maximum hop count used when the UE performs data transmission in a broadcast or multicast mode.
In different wireless communication systems, the network device may send, to the UE, indication information indicating a maximum hop count used when the UE performs data transmission in a broadcast or multicast mode in different manners.

In Wi-Fi, the network device may send indication information to the UE through a management frame.
In wimax, the network device may send indication information to the UE through a management message.
302. And the UE receives the indication information sent by the network equipment.
303. And the UE configures the hop count for data transmission in a broadcast or multicast mode according to the indication information.
After receiving the indication information sent by the network device and used for indicating the maximum hop count adopted by the UE when the UE performs data transmission in the broadcast or multicast mode, the UE may configure the hop count adopted for performing data transmission in the broadcast or multicast mode according to the received indication information.
304. And the UE transmits data by adopting a broadcast or multicast mode according to the hop count.
After the UE configures the hop count for data transmission in the broadcast or multicast mode according to the indication information, when the UE needs to transmit a data packet to other surrounding UEs, the UE may send the data packet to other surrounding UEs in the broadcast or multicast mode according to the configured hop count.
For example, when the UE1 needs to send a data packet to the surrounding UE2 in a broadcast mode, the UE1 may carry the maximum hop count in the data packet to broadcast to the surrounding UE2, at this time, after the surrounding UE2 receives the data packet, it may first determine whether the maximum hop count is carried in the data packet, if it is determined that the maximum hop count is carried in the data packet, reduce the maximum hop count by one, and continue to forward and broadcast the data packet, where the data packet to be forwarded and broadcast carries the hop count obtained after being reduced by one, and the forwarding and broadcast of the data packet is stopped until the UE receiving the data packet determines that the hop count carried in the data packet is 0.
