Description
一种上行增强传输的启动方法及相关设备 技术领域 Startup method for uplink enhanced transmission and related equipment
本发明涉及移动网络领域,尤其涉及一种上行增强传输的启动方法及相关 设备。 背景技术 The present invention relates to the field of mobile networks, and in particular, to a method and a related device for starting uplink enhanced transmission. Background technique
在 LTE(Long Term Evolution, 长期演进)系统中, UE ( User Equipment, 用户终端)每次传输上行数据时都需要发送 SR ( Scheduling Request, 调度请 求), 并在 PDCCH ( Physical Downlink Control Channel, 物理下行控制信道) 上等待授权, 只有在 PDCCH上收到授权的 UE才可以进行上行数据传输。 UE 在 PDCCH 上收到授权之后, 通过 PHICH ( Physical Hybrid ARQ Indicator Channel , 物理混合自动重传指示信道)反馈上行数据。 在上述场景中, 当上 行存在大量的小包业务时, 每个小包业务的传输都需要占用 PDCCH, 使得 PDCCH占用信道资源数量增加, 在信道资源数量总和一定的情况下, 从而引 起上行容量受限, 导致出现 PUSCH ( Physical Uplink Shared Channel, 物理上 行共享信道) 利用率不高的问题。 In the LTE (Long Term Evolution) system, the UE (User Equipment) needs to send an SR (Scheduling Request) every time the uplink data is transmitted, and is in the Physical Downlink Control Channel (Physical Downlink Control Channel). Waiting for authorization on the control channel), only the UE receiving the grant on the PDCCH can perform uplink data transmission. After receiving the authorization on the PDCCH, the UE feeds back the uplink data through the PHICH (Physical Hybrid ARQ Indicator Channel). In the foregoing scenario, when a large number of packet services exist in the uplink, the transmission of each packet service needs to occupy the PDCCH, so that the number of PDCCH occupied channel resources increases, and when the total number of channel resources is constant, the uplink capacity is limited. The problem that the utilization rate of the Physical Uplink Shared Channel (PUSCH) is not high is caused.
在现有技术方案中,提出一种基于 PDCCH Less (减少 )的上行增强传输, 预留一部分上行资源, UE 以竟争的形式在这部分资源上发送预留请求, eNodeB ( Evolved Node B, 基站 )通过 PRICH ( Physical Reservation Indication Control Channel, 物理预留指示控制信道)指示 UE的预留请求是否成功, 如 果成功则 UE可继续使用这部分资源, 否则进行等待。 但是, 该技术方案没有 解决如何初始化并启动上行增强传输的技术问题,对上行增强传输的使用不够 合理高效。 发明内容 In the prior art solution, an uplink enhanced transmission based on PDCCH Less is proposed, and a part of the uplink resource is reserved, and the UE sends a reservation request on the part of the resource in the form of contention, the eNodeB (Evolved Node B, the base station) The PRICH (Physical Reservation Indication Control Channel) indicates whether the UE's reservation request is successful. If successful, the UE may continue to use the part of the resource, otherwise it waits. However, this technical solution does not solve the technical problem of how to initialize and start the uplink enhanced transmission, and the use of the uplink enhanced transmission is not reasonable and efficient.

请参考图 5, 图 5是本发明第二实施例提供的一种上行增强传输的启动方 法的流程图。 如图所示, 本发明实施例中的方法包括: Referring to FIG. 5, FIG. 5 is a flowchart of a method for starting uplink enhanced transmission according to a second embodiment of the present invention. As shown in the figure, the method in the embodiment of the present invention includes:
5501 , 基站向用户终端发送预设的上行增强传输的启动条件。 其中, 所述 启动条件包括连接状态下的用户终端中处于激活态的数据业务包含指定数据 业务、连接状态下的用户终端中处于激活态的指定数据业务数量与处于激活态 的所有数据业务数量的比值大于预设比值以及连接状态下的用户终端的导频 信道的信噪比不低于预设门限值, 但不局限于上述启动条件。 S501. The base station sends a preset uplink enhanced transmission start condition to the user terminal. The start condition includes that the data service in the active state in the connected state includes the specified data service, the number of designated data services in the activated state in the user terminal in the connected state, and the number of all data services in the active state. The signal-to-noise ratio of the pilot channel whose ratio is greater than the preset ratio and the user terminal in the connected state is not lower than the preset threshold, but is not limited to the above-mentioned starting condition.
5502, 用户终端确认当前数据业务状况是否符合所述启动条件。 S502: The user terminal confirms whether the current data service status meets the start condition.
具体实现中, 用户终端在接收到上述启动条件之后, 可以确认自身的数据 业务状况是否符合启动条件中的一个或多个,若自身的数据业务状况符合启动 条件中的一个或多个, 则发送确认消息。若自身的数据业务状况不符合启动条 件中的任意一个, 则可以对自身数据业务状况进行实时跟踪并检查, 直到自身 的数据业务状况符合启动条件中的一个或多个。 例如, 连接状态下的用户终端 中处于激活态的数据业务包括移动冲浪、 网络游戏、 数据包下载等, 其中, 数
据包下载为指定数据业务,此时该用户终端可以确认自身的数据业务状况符合 启动条件。 In a specific implementation, after receiving the foregoing start condition, the user terminal may confirm whether the data service status of the user meets one or more of the start conditions, and if the data service status of the user meets one or more of the start conditions, Confirm the message. If the data service status of the user does not meet any of the start conditions, the data service status can be tracked and checked in real time until the data service status of the user meets one or more of the start conditions. For example, the data service in the active state in the connected state includes mobile surfing, online games, data packet downloading, etc. According to the package download as the designated data service, the user terminal can confirm that the data service status of the user meets the start condition.
5503, 当确认当前数据业务符合所述启动条件时,用户终端将确认消息发 送至所述基站。 5503. When it is confirmed that the current data service meets the start condition, the user terminal sends an acknowledgement message to the base station.
可选地, 当确认当前数据业务符合所述启动条件时, 可以通过 MAC控制 信息单元将确认消息发送至所述基站。 其中, MAC 控制信息单元用来传输 MAC层的消息,用户终端可以使用 MAC控制信息单元通知 eNodeB当前将要 发送的数据的大小。 在 MAC PDU格式中, MAC头位于 MAC控制信息单元 前, MAC头中的 LCID可以用于指示 MAC控制信息单元的消息类型。 Optionally, when it is confirmed that the current data service meets the start condition, an acknowledgement message may be sent to the base station by using a MAC control information unit. The MAC control information element is used to transmit the message of the MAC layer, and the user terminal may use the MAC control information element to notify the eNodeB of the size of the data to be sent currently. In the MAC PDU format, the MAC header is located before the MAC Control Information Element, and the LCID in the MAC header can be used to indicate the message type of the MAC Control Information Element.
可选地, 当确认当前数据业务符合所述启动条件时,通过专用信令将确认 消息发送至所述基站。 其中, 专用信令可以指导用户终端与基站之间建立临时 通信信道并协同运行。 Optionally, when it is confirmed that the current data service meets the start condition, an acknowledgement message is sent to the base station by dedicated signaling. The dedicated signaling can guide the user terminal to establish a temporary communication channel with the base station and operate in cooperation.
可选地, 当确认当前数据业务符合所述启动条件时,将携带有确认消息的 调度请求发送至所述基站, 所述调度请求使用无线网络标识 RNTI进行加扰, 所述无线网络标识 RNTI通过高层信令发送,用于区分用户终端发送的所述调 度请求。 具体实现中, 每个用户终端可以在 eNodeB预配置的 PUCCH信道的 固定位置上周期性的发送调度请求, 从而向 eNodeB请求调度资源。 其中, 调 度请求釆用码分复用方式进行传输, 多个用户终端可以占用相同的时频资源, 并通过不同的码字来进行区分。 Optionally, when it is confirmed that the current data service meets the start condition, sending a scheduling request carrying an acknowledgement message to the base station, where the scheduling request is scrambled by using a wireless network identifier RNTI, where the wireless network identifier RNTI passes The high layer signaling is used to distinguish the scheduling request sent by the user terminal. In a specific implementation, each user terminal may periodically send a scheduling request at a fixed location of the pre-configured PUCCH channel of the eNodeB, thereby requesting scheduling resources from the eNodeB. The scheduling request is transmitted by using code division multiplexing, and multiple user terminals can occupy the same time-frequency resource and distinguish by different code words.

The LTE system defines two dedicated channel resource units: a resource particle group REG and a control channel unit CCE, and one CCE is composed of 9 REGs. In a specific implementation, the number of CCEs occupied by the downlink common control channel depends on the downlink channel environment in which the UE is located, and the downlink channel ring is For a good user terminal, the eNodeB may only need to allocate one CCE, and for a user terminal with a poor downlink channel environment, the eNodeB may need to allocate up to 8 CCEs. Therefore, by counting the number of channel resources allocated by all user terminals, the number of channel resources occupied by the current downlink common control channel can be calculated.
