Description
混合自动重传请求的定时方法及装置 技术领域 Timing method and device for hybrid automatic repeat request
本发明涉及自动重传技术, 尤其涉及一种混合自动重传请求的定时方 法和装置。 背景技术 The present invention relates to automatic retransmission techniques, and more particularly to a timing method and apparatus for hybrid automatic repeat request. Background technique
混合自动重传请求 ( HARQ, Hybrid Automatic Repeat Request )技术是 对传统自动重传请求 ( ARQ , Automatic Repeat Request )技术的改进。 HARQ 技术结合了 ARQ技术和前向纠错(FEC )技术, 进而减小了时变衰落信道 对接收数据误码率的影响, 使无线通信系统能够提供更高更稳定的数据吞 吐。 HARQ 是目前主流的 4G 系统, 例如长期演进 ( LTE , Long-Term Evolution ) 系统和 IEEE 802.16m系统的关键技术之一。 Hybrid Automatic Repeat Request ( HARQ) technology is an improvement on the traditional automatic repeat request (ARQ) technology. HARQ technology combines ARQ technology with Forward Error Correction (FEC) technology to reduce the impact of time-varying fading channels on the bit error rate of received data, enabling wireless communication systems to provide higher and more stable data throughput. HARQ is one of the key technologies of the current mainstream 4G systems, such as the Long Term Evolution (LTE), Long-Term Evolution (LTE) system and the IEEE 802.16m system.
在频分双工 ( FDD, Frequency Division Duplex ) 系统中, 上行链路 /下 行链路可以同时传输数据或信号。 为了减少由于系统链路结构造成的系统 延时, 以及灵活分配上行链路 /下行链路上的数据载荷, 通常将一个无线帧 进一步划分为多个时间粒度更小的子帧。 其中, 一个数据包所占的子帧数 (即时间长度 )为数据包的传输时间间隔( TTI , Transmission Time Interval )。 图 1是相关技术的无线帧结构的示意图, 如图 1所示的无线帧结构中, 一 个无线帧被划分为 8个子帧, 按照顺序递增的原则, 对所有无线帧进行顺 序编号, 筒称帧号, 8个子帧分别表示为 SF0~SF7, 其中, 上行链路与下行 链路具有相同的帧结构。 In a Frequency Division Duplex (FDD) system, the uplink/downlink can simultaneously transmit data or signals. In order to reduce the system delay caused by the system link structure and to flexibly allocate the data payload on the uplink/downlink, one radio frame is usually further divided into a plurality of subframes with smaller time granularity. The number of subframes (that is, the length of time) occupied by one data packet is the transmission time interval (TTI, Transmission Time Interval) of the data packet. 1 is a schematic diagram of a radio frame structure of the related art. In the radio frame structure shown in FIG. 1, a radio frame is divided into 8 sub-frames, and all radio frames are sequentially numbered according to the principle of sequential increment. No. 8 sub-frames are denoted as SF0~SF7, respectively, where the uplink and the downlink have the same frame structure.
对于一个下行 HARQ过程, 下行链路上的一个或多个子帧被分配给该 HARQ 过程, 用于承载数据信道, 相应地, 上行链路上的一个或多个子帧 也被分配给该 HARQ过程,用于承载反馈信道。同样,对于一个上行 HARQ
过程, 上行链路上的一个或多个子帧被分配给该 HARQ过程, 用于承载数 据信道,相应地, 下行链路上的一个或多个子帧也被分配给该 HARQ过程, 用于承载反馈信道。 例如, 对于一个上行 HARQ过程, 上行链路上的一个 或多个上行子帧用于承载数据信道, 相应地, 下行链路上的一个或多个下 行子帧用于承载与数据信道对应的反馈信道。 For a downlink HARQ process, one or more subframes on the downlink are allocated to the HARQ process for carrying a data channel, and accordingly, one or more subframes on the uplink are also assigned to the HARQ process. Used to carry a feedback channel. Again, for an upstream HARQ Procedure, one or more subframes on the uplink are allocated to the HARQ process for carrying a data channel, and accordingly, one or more subframes on the downlink are also allocated to the HARQ process for carrying feedback channel. For example, for an uplink HARQ process, one or more uplink subframes on the uplink are used to carry a data channel, and correspondingly, one or more downlink subframes on the downlink are used to carry feedback corresponding to the data channel. channel.
接收端在接收到数据信道携带的数据后, 需要一定的处理时间才能确 定与数据对应的反馈信号(该反馈信号携带在反馈信道上), 其中, 处理时 间称为接收处理时延, 反馈信道通过预定的映射关系承载在对应的子帧上。 After receiving the data carried by the data channel, the receiving end needs a certain processing time to determine the feedback signal corresponding to the data (the feedback signal is carried on the feedback channel), wherein the processing time is called the receiving processing delay, and the feedback channel is passed. The predetermined mapping relationship is carried on the corresponding subframe.
在时分双工 (TDD, Time Division Duplex ) 系统中, 对于基于 OFDM 或 OFDMA的无线通信系统, 其无线资源映射主要依据该无线通信系统的 帧结构和资源结构, 帧结构用于描述无线资源在时域上的控制结构, 资源 结构用于描述无线资源在频域上的控制结构。 帧结构将无线资源在时域上 划分为不同等级的单位,如超帧( Superframe )、帧( Frame )、子帧( Subframe ) 和符号(Symbol ), 通过设置不同的控制信道, 例如, 广播信道、 单播和多 播信道等来实现调度控制。 In a Time Division Duplex (TDD) system, for a wireless communication system based on OFDM or OFDMA, the radio resource mapping is mainly based on the frame structure and resource structure of the wireless communication system, and the frame structure is used to describe the radio resources in time. The control structure on the domain, the resource structure is used to describe the control structure of the radio resources in the frequency domain. The frame structure divides the radio resources into different levels of units in the time domain, such as a superframe, a frame, a subframe, and a symbol, by setting different control channels, for example, a broadcast channel. , unicast and multicast channels, etc. to achieve scheduling control.
图 2是相关技术的无线通信系统的帧结构的示意图, 如图 2所示, 无 线资源在时域上划分为超帧, 每个超帧包含 4个帧, 每个帧包含 8个子帧, 子帧由 6个基本的 OFDMA符号组成。 在实际系统中, 根据需要支持的带 宽和 /或 OFDMA符号的循环前缀长度等因素, 确定帧结构中各个等级单位 中具体包含多少个 OFDMA符号。 其中每个帧中可以包含若干个下行子帧 和上行子帧, 在下行子帧发送的数据包由基站发送给终端, 终端再通过上 行子帧进行 HARQ反馈; 同样, 在上行子帧发送的数据包由终端发送给基 站, 基站再通过下行子帧进行 HARQ反馈。 2 is a schematic diagram of a frame structure of a related art wireless communication system. As shown in FIG. 2, a radio resource is divided into super frames in a time domain, each super frame includes 4 frames, and each frame includes 8 subframes, and a sub-frame The frame consists of six basic OFDMA symbols. In an actual system, the number of OFDMA symbols included in each level unit in the frame structure is determined according to factors such as the bandwidth to be supported and/or the cyclic prefix length of the OFDMA symbol. Each of the frames may include a plurality of downlink subframes and uplink subframes, and the data packets sent in the downlink subframe are sent by the base station to the terminal, and the terminal performs HARQ feedback through the uplink subframe. Similarly, the data sent in the uplink subframe. The packet is sent by the terminal to the base station, and the base station performs HARQ feedback through the downlink subframe.
此外, 系统可以在超帧中的第一个下行子帧内设置广播信道(由于位 于超帧头部, 广播信道也称为超帧头 (SFH, Superframe Header ) )并发送
资源映射等系统信息; 且系统还可以设置单播和 /多播性质的控制信道发送 资源分配等调度控制信息。 同时, 系统还可以有高级 MAP信道(A-MAP, Advanced MAP )信道, A-MAP信道位于下行子帧上, 传送服务控制信息, 至少可以包括 Non user-specific A-MAP , HARQ feedback A-MAP , Power control A-MAP, Assignment A-MAP等控制信息之一或任意组合。 广播信道 (超帧头)和 A-MAP ( Advanced MAP )信道又可以称为控制信道。 In addition, the system can set a broadcast channel in the first downlink subframe in the superframe (because it is located in the superframe header, the broadcast channel is also called a superframe header (SFH)) and send System information such as resource mapping; and the system may also set scheduling control information such as unicast and/or multicast-type control channel transmission resource allocation. At the same time, the system may also have an Advanced MAP channel (A-MAP, Advanced MAP) channel, and the A-MAP channel is located in the downlink subframe, and transmits service control information, and may include at least a user-specific A-MAP and a HARQ feedback A-MAP. , one or any combination of control information such as Power control A-MAP, Assignment A-MAP. The broadcast channel (superframe header) and the A-MAP (Advanced MAP) channel may also be referred to as a control channel.
在目前的相关技术中, 计算 HARQ定时的公式虽然可以适用于各种情 况, 且不需要大量空间存储, 但是目前的公式对某些情况下的处理不够完 善, 例如, 在频分双工 ( FDD , Frequency Division Duplex ) 下行模式下, 反馈往往需要等待较长时间, 使得整个 HARQ的处理时间变得较长。 在通 信系统中, 发送数据包、发送 A-MAP和发送反馈等操作都发生在某一特定 的时刻, 在本说明书中某一时刻指的是某个帧的某一具体子帧。 In the current related art, the formula for calculating HARQ timing can be applied to various situations and does not require a large amount of space storage, but the current formula is not perfect for processing in some cases, for example, in frequency division duplex (FDD) , Frequency Division Duplex ) In the downlink mode, feedback often needs to wait for a long time, making the processing time of the entire HARQ longer. In a communication system, operations such as transmitting a data packet, transmitting an A-MAP, and transmitting a feedback occur at a specific time, and a certain time in the present specification refers to a specific subframe of a certain frame.
图 3是相关技术的 FDD模式 HARQ下行反馈的示意图。 如图 3所示, 系统存在 8个子帧, 假设终端处理数据的时间 TprocMS = 4, 序号为 1的 子帧携带分配的下行数据包, 这样, 终端固定的反馈子帧号为 5。 如果终端 在发送序号为 5 的子帧时尚未结束对数据包的处理, 则终端需要延迟到下 一帧的序号为 5的子帧来发送该 HARQ反馈。可以看出,在 FDD下行模式 下, 终端在完成对数据包处理并可以发送反馈信息后可能需要等待一定时 间, 有时候等待时间可以接近一个帧的时间。 FIG. 3 is a schematic diagram of a related art FDD mode HARQ downlink feedback. As shown in FIG. 3, the system has 8 subframes. Assume that the terminal processes data at the time Tproc MS = 4, and the subframe numbered 1 carries the allocated downlink data packet. Thus, the terminal has a fixed feedback subframe number of 5. If the terminal has not finished processing the data packet when transmitting the subframe with the sequence number of 5, the terminal needs to delay the subframe with the sequence number 5 of the next frame to send the HARQ feedback. It can be seen that in the FDD downlink mode, the terminal may need to wait for a certain time after completing the processing of the data packet and can send the feedback information, and sometimes the waiting time can be close to one frame time.
针对相关技术中 HARQ定时方法存在延时较大的问题, 目前尚未提出 有效的解决方案。 发明内容 Aiming at the problem that the HARQ timing method has a large delay in the related art, an effective solution has not been proposed yet. Summary of the invention

The sub-frame number appears. According to the method of the present invention, if the terminal transmits feedback information in the nth uplink subframe of the jth frame, the frame number j and the subframe number n at the time of feedback can be calculated by using formula (1) and formula (2), so as to Send feedback information on the nth subframe of the jth frame: j = i + floor((Delay + m) l F) (丄) n = {Delay + m) mod F (2) where Represents the largest integer less than or equal to x; Delay is determined by at least one of terminal processing time, TTI, and guard time; Mod represents a modulo operation.

If N A _MAP is greater than 1, then Z is used to indicate that the HARQ sub-packet and the A-MAP information may be located in the same subframe, or that the HARQ sub-packet may be located in the subframe where the A-MAP information is located. After the first sub-frame. Where / for a packet with a TTI greater than 1, it refers to the location where the packet starts, not the location where the AM AP information element (IE, Information Element) appears, and the value is always equal to 0, the corresponding A- of the packet The MAP IE appears between the second downlink subframe of the previous frame and the first subframe of the current frame. / For a packet with a TTI equal to 1, it refers to the location where the packet starts and the location where the A-MAP IE appears.

在 FDD下行模式下, 根据终端处理时间、 TTI和保护时间中的至少一 个, 可以通过公式 (3)来计算延迟时间 Delay: In the FDD downlink mode, the delay time Delay can be calculated by the formula (3) according to at least one of the terminal processing time, the TTI, and the guard time:
Delay = Vm + TprocMS + P (3) 其中, NTT^ 的是数据包的 TTI对应的子帧数目, P为保护时间, 用于 预留一定的冗余时间, P可以默认为 0。 这里, 通过公式 (3)来计算 Delay只 是一个示例, 本发明实施例不仅限于此, 例如, Delay还可以等于 NTTI、 TprocMS或 P的值, 也可以等于它们两两组合之和。 Delay = V m + Tproc MS + P (3) where N TT ^ is the number of subframes corresponding to the TTI of the packet, P is the guard time, which is used to reserve a certain redundancy time, and P can default to 0. Here, the calculation of the Delay by the formula (3) is only an example, and the embodiment of the present invention is not limited thereto. For example, the Delay may also be equal to the value of N TTI , TprocMS or P, or may be equal to the sum of the two combinations thereof.
此外, 当终端处理数据的时间 TprocMS和 /或基站处理数据的时间 Tproces为固定值时, 可以根据系统中一个帧的子帧数目来确定基站处理数 据的时间 Tproces和终端处理数据的时间 TprocMS , 其中, 在终端发送数据 时, ^^^s为终端发送数据所需的处理时间7 在终端接收数据 时, TProc 为终端接收数据后发送反馈 ACK/NACK的时间 TPWCMS—RE

TprocMS = floor((x - ) / 2) + 2,0 < < 8 (4) TprocBS = floor((x - ) / 2) + 2,0 < j < 8 (5) 其中, y^^o)表示小于等于 X的最大整数,x为一个帧中的子帧数目。 可以看出, 在 i和 j取不同值的情况下, 根据一个帧中的子帧数目确定出的Tproc MS = floor((x - ) / 2) + 2,0 << 8 ( 4 ) Tproc BS = floor((x - ) / 2) + 2,0 < j < 8 (5) where y^^ o) represents the largest integer less than or equal to X, where x is the number of subframes in a frame. It can be seen that, in the case where i and j take different values, it is determined according to the number of subframes in one frame.
Tproces和 rocMs不同。 Tproces is different from rocMs.
例如, 在 i=6以及 j=6的情况下, 当一个帧上有 6或 7个子帧时, 则 TprocBS和 TprocMS等于 2; 当一个帧上有 8个子帧时, TprocBS和 TprocMS 等于 3。 For example, in the case of i=6 and j=6, when there are 6 or 7 subframes in a frame, then Tproc BS and Tproc MS are equal to 2; when there are 8 subframes in a frame, Tproc BS and Tproc MS Equal to 3.

发送模块 604,用于在确定出的反馈时刻发送混合自动重传请求的反馈 消息。 The sending module 604 is configured to send a feedback message of the hybrid automatic repeat request at the determined feedback moment.
在 FDD下行模式下不对某一子帧发送的数据设定固定的反馈子帧号, 而根据终端处理时间、 TTI和保护时间中的至少一个来确定反馈时间 ,这样, 终端只要完成对数据包的处理就可以发送, 而不需要等待固定的帧号出现, 从而缩短了 HARQ的反馈时间, 提高了 HARQ反馈的速度。 In the FDD downlink mode, a fixed feedback subframe number is not set for the data sent by a certain subframe, and the feedback time is determined according to at least one of the terminal processing time, the TTI, and the guard time, so that the terminal only needs to complete the data packet. Processing can be sent without waiting for a fixed frame number to appear, thereby shortening the HARQ feedback time and improving the speed of HARQ feedback.
假设 TprocMS表示终端处理数据的时间,根据不同的情况, 终端处理数 据的时间可以固定不变, 也可以根据终端和基站的情况而改变。 在这个基 础上, 如果系统的一个帧上有 F个子帧, 基站在第 i帧的第 m个下行子帧 上发送了数据包, 那么终端只需要等待一个特定时间 Delay即可进行反馈, 而不需要等待某一个固定的子帧号出现。 根据本发明实施例, 假设终端在 第 j帧的第 n个上行子帧发送反馈信息, 则计算模块 602可以通过公式 (1)、 公式 (2)计算反馈时的帧号 j以及子帧号 n:
优选的, 可以通过公式 (3)计算 Delay。 It is assumed that the Tproc MS indicates the time at which the terminal processes the data. The time for processing the data by the terminal may be fixed according to different situations, or may be changed according to the situation of the terminal and the base station. On this basis, if there are F subframes in one frame of the system and the base station sends a data packet on the mth downlink subframe of the ith frame, the terminal only needs to wait for a specific time Delay to perform feedback, instead of Need to wait for a fixed subframe number to appear. According to the embodiment of the present invention, if the terminal sends feedback information in the nth uplink subframe of the jth frame, the calculation module 602 can calculate the frame number j and the subframe number n when the feedback is performed by using formulas (1) and (2). : Preferably, the Delay can be calculated by the formula (3).
在 TprocMS或 TprocBs为固定值时, 可以根据系统中一个帧的子帧数目 来确定基站处理数据的时间 TprocBs和终端处理数据的时间 TprocMS,例如, 根据一个帧中的子帧数目来确定 TprocBs和终端处理数据的时间 TprocMS , 如公式 (4)和公式 (5)所示。 When the Tproc MS or the TprocBs is a fixed value, the time TprocBs of the base station processing data and the time TprocMS of the terminal processing data may be determined according to the number of subframes of one frame in the system, for example, determining TprocBs according to the number of subframes in one frame. The time TprocMS at which the terminal processes the data, as shown in equations (4) and (5).
另外, 本例举的是 FDD模式下的例子, 对于 TDD模式, 只要有相应 的 TprocBS或 TprocMS也可以用同样的方法确定 TprocBS或 TprocMS。 In addition, this example is an example in FDD mode. For TDD mode, Tproc BS or Tproc MS can be determined in the same way as long as there is a corresponding Tproc BS or Tproc MS .
当终端处理数据的时间 TprocMS为不固定值时, 基站可以在通信系统 的控制信道或控制消息中发送第一指示信令, 其中, 所述控制信道包括超 帧头或 A-MAP信道, 所述控制消息包括能力协商消息或注册消息, 或者, 终端可以在通信系统的能力协商消息或注册消息中发送第二指示信令, 上 述第一指示信令和第二指示信令用于指示终端处理数据的时间 TprocMS的 取值。 When the time Tproc MS of the terminal processing data is not a fixed value, the base station may send the first indication signaling in a control channel or a control message of the communication system, where the control channel includes a super frame header or an A-MAP channel. The control message includes a capability negotiation message or a registration message, or the terminal may send the second indication signaling in the capability negotiation message or the registration message of the communication system, where the first indication signaling and the second indication signaling are used to indicate the terminal processing. The value of the data Tproc MS .
当基站处理数据的时间 TprocBS为不固定值时, 基站可以在通信系统 的控制信道或控制消息中发送第三指示信令, 其中, 所述控制信道包括超 帧头或 A-MAP信道, 所述控制消息包括能力协商消息或注册消息。 上述第 三指示信令用于指示基站处理数据的时间 TprocBS的取值。 When the time Tproc BS of the data processing by the base station is a non-fixed value, the base station may send the third indication signaling in a control channel or a control message of the communication system, where the control channel includes a super frame header or an A-MAP channel. The control message includes a capability negotiation message or a registration message. The third indication signaling is used to indicate the value of the time Tproc BS that the base station processes the data.
另外, 本例举的是 FDD模式下的例子, 对于 TDD模式, 只要有相应 的 TprocBS或 TprocMS也可以用同样的方法确定 TprocBS或 TprocMS。 In addition, this example is an example in FDD mode. For TDD mode, Tproc BS or Tproc MS can be determined in the same way as long as there is a corresponding Tproc BS or Tproc MS .
根据本发明实施例, 对于 FDD下行模式, 按照终端处理时间、 传输时 间间隔和保护时间中的至少之一来确定终端的反馈时间, 从而保证了终端 在最快时间内完成 HARQ反馈,避免了反馈的等待时间过长,提高了 HARQ 反馈的速度。 According to the embodiment of the present invention, for the FDD downlink mode, the feedback time of the terminal is determined according to at least one of the terminal processing time, the transmission time interval, and the protection time, thereby ensuring that the terminal completes the HARQ feedback in the fastest time and avoids the feedback. The waiting time is too long, which improves the speed of HARQ feedback.
