Definitions

- D2D device-to-device
- FIG. 1 is a schematic diagram of the application scenario of D2D in the related art. As shown in Figure 1, there are mainly three scenarios:
- UE 1 and UE 2 perform data interaction under the coverage of the cellular network, and the user plane data does not pass through the network infrastructure.
- 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 user equipments, for example, within the scope of D2D direct communication, or for judging/determining.
- the first user equipment is adjacent to the second user equipment; the D2D communication technology enables some or all of the communication data between the D2D user equipments to communicate directly through the network infrastructure.

Description
通信资源管理方法、 设备、 ***及计算机存储介质 技术领域 Communication resource management method, device, system and computer storage medium
本发明涉及通信技术, 尤其涉及一种通信资源管理方法、 设备、 *** 及计算机存储介质。 背景技术 The present invention relates to communication technologies, and in particular, to a communication resource management method, device, system, and computer storage medium. Background technique
随着无线多媒体业务的发展, 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及邻近服务(PS, Proximity Services )的需求逐 渐增加, 传统的基于小区的蜂窝网络对高数据速率以及邻近服务支持方面 存在局限性, 在这种需求背景下, 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、 减少用户终端(UE, User Equipment )的电池功耗、 提 高数据速率, 并改善网络基础设施的鲁棒性, 满足高数据速率业务和邻近 服务的要求。 With the development of wireless multimedia services, the demand for high data rates and user experience is increasing, which puts high demands on the system capacity and coverage of traditional cellular networks. On the other hand, social networks, close-range data sharing, local advertising, etc. The popularity of applications has led to an increasing demand for people and things that are interested in nearby communications and proximity services (PS, Proximity Services). Traditional cell-based cellular networks have limitations for high data rates and proximity service support. Sexuality, in the context of this demand, device-to-device (D2D) technology, which represents a new direction for the development of future communication technologies, has emerged. The application of D2D technology can reduce the burden on cellular networks and reduce user terminals ( UE, User Equipment) battery power consumption, increased data rate, and improved network infrastructure robustness to meet the requirements of high data rate services and proximity services.
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, 图 1为相关 技术中 D2D的应用场景示意图, 如图 1所示, 主要有三种场景: D2D technology can work in licensed or unlicensed frequency bands, allowing multiple D2D-enabled user equipments, namely D2D User Equipment (D2D User Equipment) to perform direct discovery without network infrastructure or network infrastructure. / Direct communication, Figure 1 is a schematic diagram of the application scenario of D2D in the related art. As shown in Figure 1, there are mainly three scenarios:
1 ) UE 1和 UE 2在蜂窝网络的覆盖下进行数据交互, 用户面数据不经 过网络基础设施。 1) UE 1 and UE 2 perform data interaction under the coverage of the cellular network, and the user plane data does not pass through the network infrastructure.
2 )在弱 /无覆盖区域的 UE中继传输, 允许信号质量较差的 UE 4通过 附近有网络覆盖的 UE 3与网络进行通信, 能帮助运营商扩展覆盖、 提高容
量。 2) UE relay transmission in the weak/uncovered area, allowing the UE 4 with poor signal quality to communicate with the network through the UE 3 with network coverage nearby, which can help the operator to expand the coverage and improve the capacity. the amount.
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, UE5 , UE6和 UE7间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。 3) In the event of an earthquake or emergency, if the cellular network is not working properly, direct communication between devices is allowed, and the control plane and user plane between UE5, UE6 and UE7 do not go through the network infrastructure for one-hop or multi-hop data. Communication.
D2D技术通常包括 D2D发现技术和 D2D通信技术, D2D发现技术用 于判断 /确定两个或多个 D2D用户设备之间相互邻近, 例如在可进行 D2D 直接通信范围之内,或用于判断 /确定第一用户设备邻近第二用户设备; D2D 通信技术, 使 D2D用户设备之间部分或全部通信数据可以不通过网络基础 设施, 即直接进行通信。 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 user equipments, for example, within the scope of D2D direct communication, or for judging/determining. The first user equipment is adjacent to the second user equipment; the D2D communication technology enables some or all of the communication data between the D2D user equipments to communicate directly through the network infrastructure.
D2D通信可复用蜂窝通信资源, 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。 基站调度分配 D2D通信资源的方式通常有以下三种: D2D communication can multiplex cellular communication resources. In the scenario with cellular network coverage, D2D communication resources are usually scheduled and allocated by the base station, which can improve resource reuse efficiency, and ensure network side control of D2D communication and D2D communication and cellular. The effect of interference coordination between communications. There are usually three ways for a base station to schedule allocation of D2D communication resources:
1 ) 集中式调度, 是指 UE之间的通信完全由网络侧控制。 1) Centralized scheduling means that communication between UEs is completely controlled by the network side.
2 )半集中式调度, 是指网络侧和 UE联合进行 D2D通信的调度。 2) Semi-centralized scheduling refers to the scheduling of D2D communication jointly performed by the network side and the UE.
半集中式调度方式下, 网络侧可为多个 D2D通信对 UE半静态分配相 同的 D2D通信资源池, 由 D2D通信中的控制 UE, 如, D2D通信对中的主 UE, 或 D2D组的组头 UE基于该 D2D通信资源池进行 D2D通信资源的再 分配。 In the semi-centralized scheduling mode, the network side may semi-statically allocate the same D2D communication resource pool to the UE for multiple D2D communication, and control the UE in the D2D communication, for example, the primary UE in the D2D communication pair, or the group of the D2D group. The head UE performs redistribution of D2D communication resources based on the D2D communication resource pool.
3 )分布式调度, 即 D2D通信 UE自主进行 D2D数据传输的调度。 其中半集中式调度方式是集中式调度与分布式调度方式的折衷方案, 可实现一定程度的网络侧对 D2D通信的管控并保证资源复用效率, 同时控 制基站复杂度及空口控制信令开销在合理范围。 3) Distributed scheduling, that is, D2D communication UE autonomously performs scheduling of D2D data transmission. The semi-centralized scheduling mode is a compromise between centralized scheduling and distributed scheduling. It can achieve a certain degree of network-side control of D2D communication and ensure resource reuse efficiency. At the same time, control base station complexity and air interface control signaling overhead are Reasonable range.
对于同一个 UE, 若其支持 D2D功能, 则可能同时进行与另一 D2D UE 间的 D2D通信及与基站间的蜂窝通信。 D2D通信资源复用蜂窝通信资源且
釆用半集中式调度情况下, 基站为 D2D UE分配的资源也可能被调度用于 蜂窝通信数据传输, 由于 D2D通信与蜂窝通信所使用的通信资源并不是由 同一个基站进行调度, 则有可能同一 UE的蜂窝通信与 D2D通信在相同子 帧进行, 导致带内杂散或设备内自干扰问题。 For the same UE, if it supports the D2D function, D2D communication with another D2D UE and cellular communication with the base station may be simultaneously performed. D2D communication resources multiplex cellular communication resources and In the case of semi-centralized scheduling, the resources allocated by the base station for the D2D UE may also be scheduled for cellular communication data transmission. Since the communication resources used by the D2D communication and the cellular communication are not scheduled by the same base station, it is possible Cellular communication and D2D communication of the same UE are performed in the same subframe, resulting in in-band spurs or self-interference in the device.
例如, D2D通信复用蜂窝上行资源场景下, UE若在同一子帧发送蜂窝 上行数据及接收 D2D通信数据,则蜂窝数据的发送将严重干扰 D2D数据的 接收, 降低资源使用效率; 另外, D2D UE在只有一个收发端的情况下, 不 能同时进行 D2D通信和蜂窝通信的收发,如果 D2D UE的蜂窝通信与 D2D 通信同时被调度, 则该 D2D通信或蜂窝通信不能顺利进行。 For example, in a scenario where the D2D communication multiplexes a cellular uplink resource, if the UE transmits cellular uplink data and receives D2D communication data in the same subframe, the transmission of the cellular data will seriously interfere with the reception of the D2D data, thereby reducing the resource use efficiency; in addition, the D2D UE In the case where there is only one transceiver, the D2D communication and the cellular communication cannot be simultaneously performed. If the cellular communication of the D2D UE and the D2D communication are simultaneously scheduled, the D2D communication or the cellular communication cannot be smoothly performed.
综上所述, 半集中式调度场景中, 如何协调蜂窝通信与 D2D通信的资 源调度, 相关技术尚无解决方案。 发明内容 本发明实施例提供通信资源管理方法、 设备、 ***及计算机存储介质, 协调蜂窝通信与设备对设备通信的资源调度, 解决同一 UE 的蜂窝通信与 D2D通信之间的带内杂散和收发自干扰问题, 进而提高资源使用效率, 提 升用户体验。 In summary, in the semi-centralized scheduling scenario, how to coordinate the resource scheduling of cellular communication and D2D communication, there is no solution for related technologies.

实施例十七 Example seventeen
本实施例描述的是进行 D2D通信的 UE由不相同基站服务时, 基站向 UE发送控制信息以协商蜂窝通信与 D2D通信资源的激活机制。 图 15为本
实施例通信资源管理的流程图。 This embodiment describes an activation mechanism in which a base station sends control information to a UE to negotiate cellular communication and D2D communication resources when a UE performing D2D communication is served by a different base station. Figure 15 is the basis Embodiment Flow chart of communication resource management.
与实施例十六不同的是, 本实施例中 UE 1和 UE 2由不同基站服务。 基站 1为 UE 1的服务基站, 基站 2为 UE 2的服务基站。 基站 1和基站 2 联合为进行 D2D通信的 UE 1和 UE 2分配 D2D通信资源池, 由 UE 2在该 资源上进行 D2D通信资源的再分配。 其中 UE 2可执行部分 D2D通信控制 功能, UE 2可以为与 UE 1正在进行 D2D通信的对端 UE,也可称为主 UE。 或者, UE 2并不与 UE 1进行 D2D通信, 但 UE 1及 D2D通信对端 UE与 UE 2在同一个 D2D组内,且 UE 2为该 D2D组的控制节点(也可称为组头)。 Different from the sixteenth embodiment, in this embodiment, UE 1 and UE 2 are served by different base stations. Base station 1 is the serving base station of UE 1, and base station 2 is the serving base station of UE 2. The base station 1 and the base station 2 jointly allocate a D2D communication resource pool for the UE 1 and the UE 2 performing D2D communication, and the UE 2 performs redistribution of the D2D communication resources on the resource. The UE 2 may perform a partial D2D communication control function, and the UE 2 may be a peer UE that is performing D2D communication with the UE 1, and may also be referred to as a primary UE. Alternatively, the UE 2 does not perform D2D communication with the UE 1, but the UE 1 and the D2D communication peer UE and the UE 2 are in the same D2D group, and the UE 2 is the control node of the D2D group (also referred to as a group header). .
步骤 1501, UE 1向 UE 2发送指示信息, 指示 UE 1检测到带内杂散和 /或自干扰问题; 或者指示 UE 1接收到蜂窝上行调度。 Step 1501: UE 1 sends indication information to UE 2, indicating that UE 1 detects an in-band spur and/or self-interference problem; or instructs UE 1 to receive a cellular uplink scheduling.
UE 1可通过检测接收的 D2D通信数据信噪比低于预设阈值, 或者在 UE 1的蜂窝通信与 D2D通信在同一子帧被调度时, 确定存在带内杂散和 / 或收发自干扰问题。 The UE 1 may determine that there is an in-band spur and/or a self-interference problem by detecting that the received signal-to-noise ratio of the D2D communication data is lower than a preset threshold, or when the cellular communication of the UE 1 and the D2D communication are scheduled in the same subframe. .
步骤 1502a, UE 1向基站 1发送指示信息, 指示 UE 1检测到带内杂散 和 /或自干扰问题。 UE 1可通过 PUCCH或 MAC控制信元或 RRC消息发送 该指示信息。 In step 1502a, UE 1 sends indication information to base station 1 indicating that UE 1 detects an in-band spur and/or self-interference problem. UE 1 may send the indication information through a PUCCH or MAC Control Cell or RRC message.
基站 1判断 UE 1的 D2D控制 UE (即 UE 2 ) 的服务基站为不相同的 基站, 并获知 UE 2的服务基站为基站 1。 The base station 1 determines that the serving base stations of the D2D control UE (i.e., UE 2) of the UE 1 are different base stations, and learns that the serving base station of the UE 2 is the base station 1.
步骤 1502b,基站 1收到 UE 1的指示信息后将指示信息发送给基站 2, 或者基站 1也可自行判断需向基站 2发送指示信息, 例如, 可根据是否有 UE 1的蜂窝调度, 或者检测到 UE 1的蜂窝通信质量较差。 Step 1502b, after receiving the indication information of the UE 1, the base station 1 sends the indication information to the base station 2, or the base station 1 may determine that the indication information needs to be sent to the base station 2, for example, according to whether there is UE 1's cellular scheduling, or detecting The cellular communication to UE 1 is of poor quality.
步骤 1502c,基站 2接收到基站 1的指示信息后向 UE 2发送指示信息。 指示 UE 2向网络侧发送辅助信息, 以辅助进行蜂窝通信与 D2D通信 之间资源协调。 基站 2可通过 PDCCH或 MAC控制信元或 RRC消息发送 该指示信息。
步骤 1501和步骤 1502a ~ 1502c为两种并列可选的激活网络侧向 UE 2 发送控制信息以进行资源协调的方式。 另外, UE 2还可以自行判断是否向 基站发送控制信息, 例如, 可根据是否有 UE 1的 D2D通信调度, 或者检 测到 UE 1的 D2D通信质量较差。 Step 1502c: After receiving the indication information of the base station 1, the base station 2 sends the indication information to the UE 2. The UE 2 is instructed to send auxiliary information to the network side to assist in resource coordination between the cellular communication and the D2D communication. The base station 2 can transmit the indication information through a PDCCH or a MAC Control Cell or an RRC message. Step 1501 and steps 1502a ~ 1502c are two parallel optional ways in which the active network side sends control information to the UE 2 for resource coordination. In addition, the UE 2 may also determine whether to send control information to the base station, for example, according to whether there is D2D communication scheduling of the UE 1, or detecting that the D2D communication quality of the UE 1 is poor.
步骤 1503 ~步骤 1505与步骤 1102〜步骤 1104相同, 这里不再赘述。 另外, UE 2还可根据自身的判断或 UE 1的指示或网络侧的指示信息 停止向网络侧发送辅助信息以进行蜂窝通信与 D2D通信资源的协调。 Steps 1503 to 1505 are the same as steps 1102 to 1104, and are not described herein again. In addition, the UE 2 may also stop sending auxiliary information to the network side to perform coordination between the cellular communication and the D2D communication resource according to its own judgment or the indication of the UE 1 or the indication information of the network side.
