Description

一种上行调度方法、基站和终端An uplink scheduling method, base station and terminal

技术领域technical field

本发明涉及通信领域，特别是指一种上行调度方法、基站和终端。The present invention relates to the field of communications, in particular to an uplink scheduling method, a base station and a terminal.

背景技术Background technique

“VoLTE”，指采用LTE网络承载语音业务(Voice over LTE)。由于LTE网络是一个全IP化的网络，话音经过语音编码器后，将形成一个个的数据包在LTE网络中进行转发。以AMR12.2kbps语音编码器为例，在通话过程中，语音编码器每20ms会产生一个320bits左右大小的语音包。"VoLTE" refers to the use of LTE network to carry voice services (Voice over LTE). Since the LTE network is an all-IP network, after the voice passes through the voice encoder, data packets will be formed one by one and forwarded in the LTE network. Taking the AMR12.2kbps voice encoder as an example, during a call, the voice encoder will generate a voice packet with a size of about 320bits every 20ms.

在无线通信系统中，当用户向小区边缘移动时，基站将通知用户提升发射功率来补偿路损的增加；当用户发射功率达到最大值后，随着路损的进一步增加，上行链路逐渐恶化，上行每TTI可传输的有效信息量将降低，甚至无法传递一个完整的VoLTE语音包。此时，终端通过RLC(无线链路控制)层分片，可有效降低每TTI需要发送的数据包大小，提升了上行边缘覆盖能力(如相同的发射功率下，当数据量降低后，可采用较为低阶的调制编码方式，上行解调能力越强)。In a wireless communication system, when the user moves to the edge of the cell, the base station will notify the user to increase the transmit power to compensate for the increase in path loss; when the user's transmit power reaches the maximum value, with the further increase of the path loss, the uplink gradually deteriorates , the effective amount of information that can be transmitted per TTI in the uplink will be reduced, and even a complete VoLTE voice packet cannot be transmitted. At this time, the terminal uses the RLC (Radio Link Control) layer fragmentation, which can effectively reduce the size of the data packet that needs to be sent per TTI, and improve the coverage of the uplink edge (for example, under the same transmit power, when the amount of data is reduced, it can be used The lower-order modulation and coding method, the stronger the uplink demodulation capability).

图1给出了RLC分片的处理流程(以RLC分两片为例)：303比特的数据，通过RLC层分片，分成两个分片数据包，一个151比特，一个152比特，每一个数据包均附着有8比特位的包头以及16位的MAC包头。Figure 1 shows the processing flow of RLC fragmentation (taking two RLC fragments as an example): 303-bit data is fragmented by the RLC layer and divided into two fragmented data packets, one with 151 bits and the other with 152 bits. Each data packet is attached with an 8-bit header and a 16-bit MAC header.

RLC分片虽然可以提升上行边缘覆盖能力，但由于每个分片均需要控制信令来指示调度，因此引入了更多的PDCCH(物理下行控制信道)开销。Although RLC slicing can improve the uplink edge coverage, since each slicing requires control signaling to indicate scheduling, more PDCCH (Physical Downlink Control Channel) overhead is introduced.

现有技术方案中，SPS(半静态调度)是一种节省PDCCH开销的有效调度方法，因此，一旦RLC层分片后，可考虑在MAC层用SPS对各个分片进行调度。根据3GPP相关协议(TS36.300)，如下表所示，表1TDD上下行子帧配比(TS 36.300)In the prior art solution, SPS (semi-persistent scheduling) is an effective scheduling method to save PDCCH overhead. Therefore, once the RLC layer is fragmented, it can be considered to use SPS to schedule each fragment at the MAC layer. According to 3GPP related protocols (TS36.300), as shown in the following table, Table 1 TDD uplink and downlink subframe ratio (TS 36.300)

上行链路的SPS参数可由eNodeB通过RRC信令进行配置。根据上行覆盖情况，一个VoLTE语音包可在RLC层被拆成2个或者4个更小的语音包。此时，对于MAC层调度器来说，VoLTE业务类型将不再是20ms周期到达一个数据包，而是根据RLC分片情况，每20ms产生2个、4个或者更多的数据包。图2为采用10ms的SPS周期调度RLC分片示意图，其中，一个语音数据包SDU是20ms，SDU0为一个RLC分片数据包，SDU1为下一个RLC分片数据包，以RLC分4片为例，如果仍采用SPS调度，即使配置为最短的10ms SPS周期，也无法及时完成RLC分片的调度传输，也会导致部分分片(即图中的TB)会占用到下一个SDU 20ms时刻，造成后面的分片无法进行被调度，这样时延会越来越长，造成时延的累积，降低了用户体验。The uplink SPS parameters can be configured by the eNodeB through RRC signaling. Depending on the uplink coverage, a VoLTE voice packet can be split into 2 or 4 smaller voice packets at the RLC layer. At this time, for the MAC layer scheduler, the VoLTE service type will no longer arrive at a data packet every 20ms, but will generate 2, 4 or more data packets every 20ms according to the RLC fragmentation. Figure 2 is a schematic diagram of scheduling RLC fragmentation using the SPS period of 10ms, in which, a voice data packet SDU is 20ms, SDU0 is an RLC fragmentation data packet, SDU1 is the next RLC fragmentation data packet, and RLC is divided into 4 fragments as an example , if SPS scheduling is still used, even if the shortest 10ms SPS period is configured, the scheduling and transmission of RLC fragments cannot be completed in time, and some fragments (ie TB in the figure) will occupy the next SDU 20ms time, resulting in The subsequent shards cannot be scheduled, so the delay will become longer and longer, resulting in the accumulation of delay and reducing the user experience.

因此，现有的SPS调度方案，没有针对RLC分片后语音业务类型的变化进行设计，导致采用SPS方案进行RLC调度传输时，由于无法及时为每个RLC分片配置传输资源，造成了数据包时延的累积。为此，基站侧还需要引入额外的PDCCH信令对未进行SPS配置的RLC分片进行动态调度，无法达到节省PDCCH开销的目的。Therefore, the existing SPS scheduling scheme is not designed for the change of the voice service type after RLC fragmentation. As a result, when the SPS scheme is used for RLC scheduling transmission, the transmission resources cannot be configured for each RLC fragmentation in time, resulting in data packets. accumulation of delays. For this reason, the base station side also needs to introduce additional PDCCH signaling to dynamically schedule the RLC slices without SPS configuration, which cannot achieve the purpose of saving PDCCH overhead.

具体实施方式Detailed ways

为使本发明要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

本发明的实施例中，所述的“SPS”，指无线通信系统媒体接入控制层(MAC，MediaAccess Control)的一种无线资源调度方案，即半持续调度(Semi-PersistentScheduling)，其主要思想是对新数据包采用持续调度，对重传的数据包采用动态调度。当系统内，存在多个具有突发性小包业务类型(如VoLTE)的用户并发时，每个用户的数据包都需要控制信令进行调度指示，控制信道容量将成为系统容量的瓶颈；此时，如采用半持续调度，可有效降低控制信令的开销，提升系统容量。In the embodiment of the present invention, the "SPS" refers to a wireless resource scheduling scheme of the Media Access Control layer (MAC, Media Access Control) of the wireless communication system, namely Semi-Persistent Scheduling (Semi-Persistent Scheduling), the main idea of which is It uses continuous scheduling for new data packets and dynamic scheduling for retransmitted data packets. When there are multiple concurrent users with bursty small-packet service types (such as VoLTE) in the system, each user's data packets need control signaling for scheduling instructions, and the control channel capacity will become the bottleneck of the system capacity; at this time , If semi-persistent scheduling is used, the overhead of control signaling can be effectively reduced and the system capacity can be improved.

本发明的实施例中所述“RLC分片数据包”，特指无线通信系统中的基站或终端在无线链路控制层(RLC，Radio Link Control)的一种数据处理方法。基站或终端在RLC层可将一个大的数据包(RLC SDU)拆分成多个小的数据包(RLC PDUs)，有效降低了每传输间隔(TTI，Time To Interval)所需发送的数据量。The "RLC fragmented data packet" in the embodiment of the present invention refers to a data processing method at the Radio Link Control layer (RLC, Radio Link Control) of a base station or a terminal in a wireless communication system. The base station or terminal can split a large data packet (RLC SDU) into multiple small data packets (RLC PDUs) at the RLC layer, effectively reducing the amount of data that needs to be sent per transmission interval (TTI, Time To Interval). .

如图3所示，本发明的实施例提供一种上行调度方法，包括：As shown in FIG. 3, an embodiment of the present invention provides an uplink scheduling method, including:

步骤31，产生终端上行传输的多个无线链路控制RLC分片数据包的调度配置信息，所述RLC分片数据包是终端上行传输的语音数据包在RLC层被分片处理后得到的；Step 31, generating the scheduling configuration information of multiple radio link control RLC fragmentation data packets transmitted by the terminal, and the RLC fragmented data packets are obtained after the voice data packets of the terminal uplink transmission are processed by fragmentation at the RLC layer;

步骤32，向终端发送所述多个RLC分片数据包的调度配置信息。Step 32: Send the scheduling configuration information of the multiple RLC fragmented data packets to the terminal.

本发明的上述实施例通过产生终端上行传输的多个无线链路控制RLC分片数据包的调度配置信息，所述RLC分片数据包是终端上行传输的语音数据包在RLC层被分片处理后得到的，并将调度配置信息发送给终，从而使基站侧可根据RLC分片情况，一次性配置多个并行子帧对RLC分片数据包进行持续调度，终端将在这多个上行子帧上采用相同的调度信息持续发送RLC分片数据包，降低了RLC分片下调度信令的开销。The above-mentioned embodiments of the present invention generate scheduling configuration information of multiple radio link control RLC fragmented data packets transmitted by the terminal in the uplink. The RLC fragmented data packets are the voice data packets transmitted by the terminal uplink and are fragmented and processed at the RLC layer. Then, the scheduling configuration information is sent to the terminal, so that the base station side can configure multiple parallel subframes at one time to continuously schedule the RLC fragmented data packets according to the RLC fragmentation situation. The same scheduling information is used on the frame to continuously send RLC fragmented data packets, which reduces the overhead of scheduling signaling under RLC fragmentation.

本发明的上述实施例中，所述调度配置信息可以包括：In the above embodiment of the present invention, the scheduling configuration information may include:

第一配置信息，用于指示终端在连续的上行子帧中发送多个RLC分片数据包；且所述连续的上行子帧的个数与多个RLC分片数据包的个数相同。The first configuration information is used to instruct the terminal to send multiple RLC fragmented data packets in consecutive uplink subframes; and the number of the continuous uplink subframes is the same as the number of multiple RLC fragmented data packets.

第二配置信息，用于指示终端在不连续的上行子帧中发送多个RLC分片数据包。The second configuration information is used to instruct the terminal to send multiple RLC fragmented data packets in discontinuous uplink subframes.

在上述实施例中，步骤32中，基站侧可通过物理下行控制信道PDCCH信令或者无线资源控制RRC信令向终端发送所述多个RLC分片数据包的调度配置信息。In the above embodiment, in step 32, the base station side may send the scheduling configuration information of the multiple RLC fragmented data packets to the terminal through physical downlink control channel PDCCH signaling or radio resource control RRC signaling.

基站侧产生调度配置信息并发送终端的具体过程包括：The specific process of generating scheduling configuration information on the base station side and sending it to the terminal includes:

步骤1：基站通过RRC消息或者PDCCH消息，将RLC分片数据包相关的调度配置信息(SPS配置)告知UE；具体来说，该SPS配置包含如下信息：Step 1: The base station notifies the UE of the scheduling configuration information (SPS configuration) related to the RLC fragmented data packet through an RRC message or a PDCCH message; specifically, the SPS configuration includes the following information:

指示当前SPS为普通SPS还是RLC分片下的SPS；Indicates whether the current SPS is a normal SPS or an SPS under RLC fragmentation;

针对RLC分片下的SPS，指示两种SPS调度配置：For SPS under RLC fragmentation, two SPS scheduling configurations are indicated:

配置0：连续发送。即终端在收到调度时，在连续的nRLC分片(包括当前调度指示的上行子帧)个上行子帧上发送RLC分片数据包，并且间隔SPS周期后再重复该操作，该SPS周期可在现有SPS配置消息中进行设置。Configuration 0: Continuous transmission. That is, when the terminal receives the scheduling, it sends the RLC fragmented data packets on consecutive n RLC fragments (including the uplink subframes indicated by the current scheduling) uplink subframes, and repeats the operation after the interval of the SPS period. Can be set in an existing SPS configuration message.

配置1：非连续发送。即终端在非连续的nRLC分片个上行子帧上来发送RLC分片，尽可能的让新数据包的调度时刻与重传RLC分片数据包的调度时刻不同，从而预留出重传时刻，新包的调度间隔与子帧配比绑定。Configuration 1: Discontinuous transmission. That is, the terminal sends RLC fragments on non-consecutive n RLC fragmented uplink subframes, and tries to make the scheduling time of the new data packet different from the scheduling time of the retransmitted RLC fragmented data packet, so as to reserve the retransmission time. , the scheduling interval of the new packet is bound to the subframe ratio.

本发明的上述实施例相比于现有技术，通过对语音数据包在RLC层进行分片处理的情况下的SPS调度算法进行了优化，即一次性配置多个并行子帧对RLC分片数据包进行持续调度，终端将在这多个上行子帧上采用相同的调度信息持续发送RLC分片数据包，避免了数据包的累积，在提升上行覆盖的同时，可有效节省控制信令的开销。Compared with the prior art, the above-mentioned embodiment of the present invention optimizes the SPS scheduling algorithm when the voice data packet is fragmented at the RLC layer, that is, configures multiple parallel subframes at one time to fragment the RLC data. The packet is continuously scheduled, and the terminal will use the same scheduling information on these multiple uplink subframes to continuously send RLC fragmented data packets, which avoids the accumulation of data packets, and can effectively save the overhead of control signaling while improving uplink coverage. .

其中，所述调度配置信息包括：Wherein, the scheduling configuration information includes:

第一配置信息，用于指示终端在连续的上行子帧中发送多个RLC分片数据包；且所述连续的上行子帧的个数与多个RLC分片数据包的个数相同；The first configuration information is used to instruct the terminal to send multiple RLC fragmented data packets in consecutive uplink subframes; and the number of the continuous uplink subframes is the same as the number of multiple RLC fragmented data packets;

本发明的一具体实施例中，上述步骤42可以包括：若所述调度配置信息为第一配置信息，在指示的上行调度时刻以及指示的上行子帧起连续的多个上行子帧中发送所述多个RLC数据包；In a specific embodiment of the present invention, the above step 42 may include: if the scheduling configuration information is the first configuration information, sending the specified uplink scheduling time and multiple consecutive uplink subframes from the indicated uplink subframe. Describe multiple RLC data packets;

若所述调度配置信息为第二配置信息，在指示的上行调度时刻以及指示的上行子帧发送第一个RLC数据包，在之后空闲的非连续的上行子帧中发送剩余的RLC数据包。If the scheduling configuration information is the second configuration information, the first RLC data packet is sent at the indicated uplink scheduling time and the indicated uplink subframe, and the remaining RLC data packets are sent in the subsequent idle non-consecutive uplink subframes.

步骤1：解析基站下发的RRC信息或者PDCCH消息，得到上行链路SPS调度的相关配置。具体来说，如果SPS配置指示当前是一次普通的SPS，则终端按照普通的SPS流程进行数据包的发送；如果指示当前是一次针对RLC分片下的SPS配置，则进入步骤2；Step 1: Parse the RRC information or PDCCH message sent by the base station to obtain the relevant configuration of uplink SPS scheduling. Specifically, if the SPS configuration indicates that it is currently an ordinary SPS, the terminal sends the data packet according to the ordinary SPS process; if the indication is that the current is an SPS configuration for RLC fragmentation, then enter step 2;

步骤2：确定后续RLC分片的调度配置，如果配置信息为0，则在收到SPS激活的调度信令指示的上行调度时刻及其连续的nRLC分片(包括当前调度指示的上行子帧)个上行子帧上传输RLC分片数据包；如果配置信息为1，在非连续的nRLC分片个上行子帧上来调度传输RLC分片，具体位置在SPS配置中指示。Step 2: Determine the scheduling configuration of subsequent RLC slices. If the configuration information is 0, then at the uplink scheduling time indicated by the scheduling signaling of SPS activation and its consecutive n RLC slices (including the uplink subframe indicated by the current scheduling) ) uplink subframes transmit RLC fragmentation data packets; if the configuration information is 1, the transmission of RLC fragments is scheduled on non-consecutive n RLC fragmented uplink subframes, and the specific location is indicated in the SPS configuration.

其中，配置信息为1时，新数据包被调度的位置可通过SPS Pattern(配置)指示，这里分别给出RLC分2片/4片场景下的SPS配置：Among them, when the configuration information is 1, the location where the new data packet is scheduled can be indicated by SPS Pattern (configuration).

当nRLC分片＝2时，SPS配置如下：When n RLC slices = 2, the SPS configuration is as follows:

在上述nRLC分片＝2时，SPS配置中，具有下划线的子帧编号为RLC的2个分片持续配置的上行子帧位置。When the above n RLC slice =2, in the SPS configuration, the subframe number with the underline is the uplink subframe position of the continuous configuration of the 2 slices of the RLC.

当nRLC分片＝4时，SPS配置如下：When n RLC slices = 4, the SPS configuration is as follows:

当nRLC分片＝4时，SPS配置中，具有下划线的子帧编号为RLC的4个分片持续配置的上行子帧位置。When n RLC slices = 4, in the SPS configuration, the subframe number with the underline is the uplink subframe position of the continuous configuration of the 4 slices of the RLC.
