- D2D technology can work in licensed or unlicensed frequency bands, allowing multiple D2D-enabled user equipments, that is, D2D User Equipment (D2D User Equipment) to directly discover without network infrastructure or network infrastructure. / Direct communication.
- D2D User Equipment D2D User Equipment
- UE1 and UE2 perform data interaction under the coverage of the cellular network, where the cellular network is a network covered by the evolved base station (eNB), and the user plane data interaction process does not pass through the network infrastructure, as shown in mode 1 of FIG. Show
- D2D technology usually includes D2D discovery technology and D2D communication technology:
- the D2D discovery technology is used to determine/determine the proximity between two or more D2D UEs, for example, to determine/determine that two or more D2D UEs are adjacent to each other within a range in which D2D direct communication is possible, or for Determining/determining that the first user equipment is adjacent to the second user equipment.
- D2D communication technology refers to a technology in which some or all of the communication data between D2D UEs can communicate directly without going through the network infrastructure.
- D2D communication resources are usually scheduled and allocated by the base station, which can improve resource reuse efficiency, and at the same time ensure the control of D2D communication and the interference coordination between D2D communication and cellular communication.
- the communication resources of the D2D UE may be dynamically scheduled by the base station, or the base station may allocate semi-persistent scheduling resources for the D2D UE.
- D2D communication requirements are robust and can still provide maximum service in the current shortage of communication resources, congestion or network infrastructure. Therefore, public safety requires D2D communication to work not only in a network coverage scenario, but also in partial coverage and no network coverage scenarios.

- Cellular communication and dynamically scheduled D2D communication therefore, affect the quality of service and user experience of cellular communications and D2D communications.
- the UE can simultaneously monitor and receive the D2D in the coverage and coverage of the serving base station. information.
- the D2D information of the same UE at the same frequency point needs to be received and transmitted in a time division manner, and when the same UE receives the D2D information and transmits the cellular data at the same frequency point, It also needs to be done in a time division manner.
- the UE when the UE performs information reception in a resource pool outside the coverage of the serving base station, if the UE monitors and receives D2D information in a resource pool that is not covered by the serving base station, at this time, if the serving base station schedules When the UE sends the cellular data or the D2D information, the UE may interfere with the resource pool outside the coverage of the serving base station to monitor and receive the D2D information, so that the receiving performance of the UE is degraded, which affects the service quality and user experience of the D2D communication.

本发明提供了一种蜂窝通信和设备到设备(D2D)通信共存的方法、***、装置及存储介质。所述方法包括:接收资源控制信息(401);根据所述资源控制信息在无网络覆盖资源池监听和接收D2D信息(402)。
Description
蜂窝通信和 D2D通信共存的方法、 ***、 装置、 存储介质 技术领域
本发明涉及无线通信技术, 尤其涉及一种蜂窝通信和设备到设备(D2D , Device-to-Device )通信共存的方法及***、 装置、 存储介质。 背景技术
随着无线多媒体业务的发展, 人们对高数据速率和用户体验的需求日益增 长, 从而对传统蜂窝网络的***容量和覆盖提出了较高要求。 另一方面社交网 络、 近距离数据共享、 本地广告等应用的流行使得人们对了解附近感兴趣的人 或事物并与之通信的需求逐渐增加; 这里, 社交网络、 近距离数据共享、 本地 广告等应用服务称为邻近服务( Proximity Services )。 传统的基于小区的蜂窝网 下, 代表未来通信技术发展新方向的设备到设备(D2D, Device-to-Device )技 术应运而生。 D2D技术的应用, 可以减轻蜂窝网络的负担、 减少用户设备的电 池功耗、 提高数据速率, 并改善网络基础设施的鲁棒性, 很好地满足上述高数 据速率业务和邻近服务的要求。
D2D技术可以工作在授权频段或非授权频段, 允许多个支持 D2D功能的 用户设备, 即 D2D用户设备( D2D UE, D2D User Equipment )在有网络基础 设施或无网络基础设施的情况下进行直接发现 /直接通信。 D2D的应用场景主要 有三种:
1 ) UE1和 UE2在蜂窝网络的覆盖下进行数据交互, 所述蜂窝网络为演进 型基站 (eNB ) 所覆盖的网络, 用户面数据交互过程不经过网络基础设施, 如 图 1中的模式 1所示;
2 )在弱 /无覆盖区域中 UE的中继传输, 如图 1 中的模式 2所示, 允许信 号质量较差的 UE4通过附近有网络覆盖的 UE3与网络进行通信, 能帮助运营
商扩展覆盖、 提高容量;
3 )在发生地震或紧急情况, 蜂窝网络不能正常工作的情况下, 允许设备间 直接通信, 如图 1中的模式 3所示, UE5、 UE6和 UE7之间的控制面和用户面 都不经过网络基础设施而进行一跳或多跳的数据通信。
D2D技术通常包括 D2D发现技术和 D2D通信技术:
1 ) D2D发现技术用于判断 /确定两个或多个 D2D UE之间相互邻近, 例如 在可进行 D2D直接通信范围之内判断 /确定两个或多个 D2D UE之间相互邻近, 或者用于判断 /确定第一用户设备邻近第二用户设备。
2 ) D2D通信技术是指 D2D UE之间部分或全部通信数据可以不通过网络 基础设施而直接进行通信的技术。
在有蜂窝网络覆盖的场景下, D2D通信资源通常由基站进行调度分配, 这 样可以提高资源复用效率, 同时保证网络侧对 D2D通信的控制以及 D2D通信 与蜂窝通信之间干扰协调的效果。 D2D UE的通信资源可以由基站动态调度, 或者基站可为 D2D UE分配半持续调度资源。 公共安全场景下, D2D通信要求 具有很强的鲁棒性, 能够在当前通信资源短缺、 拥塞或者网络基础设施瘫痪的 情况下仍然最大限度的提供服务。 因此,公共安全要求 D2D通信不仅在有网络 覆盖场景下工作, 还要求在部分覆盖以及无网络覆盖场景下工作。 在无网络覆 盖场景下, D2D UE可以通过自组织的方式工作, 并通过竟争方式与其它无网 络覆盖下 D2D UE共享同一个资源池。 无网络覆盖下共享的资源池可以在 UE 位于网络覆盖内时从邻近服务( Prose function )服务器或核心网网元处获取, 例如从邻近服务应用服务器处获取。
由于小区覆盖内的 UE需要能与服务基站进行蜂窝通信, 以及同时与服务 基站覆盖外的 D2D UE进行 D2D通信。 例如, 位于小区边缘的 UE可能需要一 边发送或接收所述服务基站覆盖外 D2D UE的 D2D信息,一边发送或接收所述 服务基站覆盖内的蜂窝数据, 或者使用所述服务基站调度的资源发送 D2D信 息。
当所述服务基站覆盖外使用的资源池的频点与所述服务基站覆盖内的蜂窝
或 D2D通信使用的频点不同时, 没有载波聚合(CA, Carrier Aggregation ) 能 力的 UE需要以时分双工的方式在这两个不同的频点上工作。 并且当 UE在所 述服务基站覆盖外资源池使用的频点上工作时, 所述 UE暂停接收或发送所述 服务基站的蜂窝数据及调度的 D2D信息, 即所述 UE无法进行所述服务基站的 蜂窝通信及动态调度的 D2D通信, 因此, 影响蜂窝通信及 D2D通信的服务质 量和用户体验。
当所述服务基站覆盖外使用的资源池的频点与所述服务基站覆盖内的蜂窝 或 D2D通信使用的频点相同时, UE可以同时监听和接收所述服务基站覆盖内 和覆盖外的 D2D信息。但由于 UE可能只有一个射频单元或由于收发自干扰现 象, 同一频点上同一 UE的 D2D信息的接收与发送需要以时分方式进行, 且同 一频点上同一 UE接收 D2D信息与发送蜂窝数据时, 也需要以时分方式进行。 具体地, 当 UE在所述服务基站覆盖外的资源池内进行信息接收时, 如所述 UE 在所述服务基站覆盖外的资源池监听和接收 D2D信息, 此时, 若所述服务基站 调度所述 UE发送蜂窝数据或 D2D信息时, 会干扰所述 UE在所述服务基站覆 盖外的资源池监听和接收 D2D信息, 使得 UE的接收性能下降, 影响 D2D通 信的服务质量和用户体验。 发明内容
