Description

Resource configuration method and device

Technical Field

The present invention relates to the field of communications, and in particular, to a resource configuration method and apparatus.

Background

With the development of wireless multimedia services, on one hand, the demands of people for high data rate and user experience are increasing; on the other hand, application scenarios such as public safety, social networking, near field data sharing, local advertising and the like have increased the demand for Proximity Services (PS) or Services called single edge connectivity (Sidelink) Services, which are Services that know and communicate with nearby people or things. As such, high demands are placed on the system capacity and coverage of conventional cellular networks.

However, conventional base station-centric cellular networks have significant limitations in terms of high data rate and proximity service support, and against this demand, Device-to-Device (D2D) technology has emerged as a new direction for future communication technology. The application of the D2D technology can reduce the burden of the cellular network, reduce the battery power consumption of the user equipment, increase the data rate, and improve the robustness of the network infrastructure, and well meet the requirements of the high data rate service and the proximity service.

Fig. 1 is a schematic diagram of direct discovery/communication performed by a D2D UE in the related art, and as shown in fig. 1, the D2D technology may operate in a licensed frequency band or an unlicensed frequency band, and allows a plurality of User equipments supporting D2D, i.e., D2D User equipments (D2D User Equipment, referred to as D2D UE), to perform direct discovery/direct communication with or without network infrastructure. Currently, there are three main application scenarios of D2D: one is that the UE1 and the UE2 interact with data under the coverage of a cellular network, and the user plane data does not pass through the network infrastructure, as shown in mode 1 in fig. 1; alternatively, as shown in mode 2 in fig. 1, for the UE4 under the first terminal transmission of the UE in the weak/no coverage area, the UE4 with poor signal quality is allowed to communicate with the network through the UE3 with network coverage nearby, which can help the operator to expand coverage and increase capacity; also, as shown in mode 3 of fig. 1, in case of earthquake or emergency, the cellular network cannot work normally, and direct communication between devices is allowed, and the control plane and the user plane between the UE5, UE6 and UE7 do not go through the network infrastructure and perform one-hop or multi-hop data communication.

The D2D technology generally includes D2D discovery technology and D2D communication technology. The D2D discovery technology is a technology for determining whether a first user equipment is adjacent to a second user equipment, and generally, a D2D UE can discover each other by transmitting or receiving a discovery signal; the D2D communication technology refers to a technology in which some or all of communication data between D2D user devices may be communicated directly without passing through a network infrastructure. The interface used by the terminal to directly communicate with the terminal using the D2D technology is a PC5 interface, and the interface used by the terminal to communicate with the serving base station is referred to as a Uu interface.

Before D2D discovery or D2D communication is performed by a D2D UE, first, corresponding radio resources need to be acquired respectively, and according to the progress of a related 3GPP standard conference, no matter the radio resources are acquired in D2D discovery or D2D communication, there are two resource allocation manners, that is, resources are acquired based on a manner that the UE selects to acquire resource allocation (herein, referred to as a first resource allocation manner for short) or dedicated resources are scheduled and allocated by a base station for the UE (herein, referred to as a second resource allocation manner for short) to perform D2D discovery or D2D communication. The first resource allocation method generally pre-allocates a D2D resource pool by a base station or a system, monitors the resource pool by a UE participating in D2D discovery or D2D communication, or a Proximity Service based UE (ProSe UE for short), and acquires radio resources by selecting a resource allocation method by the UE; and the base station allocates the appropriate wireless resources to the ProSe UE according to the request of the ProSe UE in the second resource allocation mode.

From the perspective of public security, the public safety network system needs to provide multimedia and other service means for the first responder to complete the task, and has the functions of single-point communication and intra-group communication. Specifically, the D2D communication of the public safety scenario includes the following types: unicast, multicast, broadcast. Unicast refers to a one-to-one communication mode between D2D user devices, whereas multicast and broadcast are one-to-many communication modes for D2D user devices. Unicast communication can be regarded as a special form of multicast communication, e.g. only two user equipments are included in a D2D communication group, in which case D2D multicast communication is equivalent to unicast communication. Meanwhile, the communication requirement of the public safety scene has strong robustness, and the service can still be provided to the maximum extent under the condition that the current communication resources are in shortage or are congested or the network infrastructure is paralyzed. Public safety therefore requires that D2D communication not only operate in a network coverage scenario, but also in a partial coverage and non-network coverage scenario. In the non-network coverage scenario, the D2D ues may operate in a self-organizing manner, or in the non-coverage environment, some D2D ues may be selected as Central nodes (referred to as "CN"), and the Central nodes provide functions similar to those of the base station. In order to make D2D communication better performable, the terminal often needs to discover the existence of other terminals first before performing D2D communication, so that the D2D discovery in public safety scenarios also requires support for working in partial coverage and no network coverage scenarios. In the related art, only one discovery message for advertisement is defined in R12, and a fixed-size resource block is used to carry a discovery message no larger than 232 bits. Since a new discovery message is defined in R13, and the message may be larger than 232bits, the related mechanism cannot carry the discovery message defined by R13.

In the related art, an effective solution has not been proposed so far to solve the problem that the related D2D discovery mechanism cannot carry the discovery message of R13 when the terminal needs to send the discovery message of R13 for a continuous period.
