Description

数据发送的方法和设备、数据接收的方法和设备、通信方法和***Method and device for transmitting data, method and device for receiving data, communication method and system

技术领域Technical field

本发明涉及移动通信领域，尤其涉及一种数据发送的方法和设备、数据接收的方法和设备、通信方法和***。The present invention relates to the field of mobile communications, and in particular, to a method and device for transmitting data, a method and device for receiving data, and a communication method and system.

背景技术Background technique

频谱是无线通信中非常昂贵的资源，现有的通信***通常工作在3GHz以下的载频上。由于当前的频谱资源已经难以满足需求，具有更大的可用带宽的高频频段日益成为下一代通信***的候选频段。Spectrum is a very expensive resource in wireless communications, and existing communication systems typically operate at carrier frequencies below 3 GHz. Since current spectrum resources are already difficult to meet, high-frequency bands with larger available bandwidth are increasingly becoming candidate bands for next-generation communication systems.

然而，大尺度衰落值会随着载频的增加而增加，且高频下的信道接收质量会随着载频的增加而减少。一种解决方法为通过更大的天线增益来补偿该载频增加所带来的大尺度衰落的增加和信道接收质量的降低，例如基于天线阵列的波束赋形技术。在波束较窄，每个方向的波束只能覆盖小区内的部分用户的情况下，为保证小区内所有用户都能够被覆盖，通常需要进行时分的波束切换。However, the large-scale fading value increases as the carrier frequency increases, and the channel reception quality at high frequencies decreases as the carrier frequency increases. One solution is to compensate for the increase in large-scale fading and the degradation of channel reception quality due to the increase in carrier frequency by a larger antenna gain, such as beamforming techniques based on antenna arrays. In the case that the beam is narrow and the beam in each direction can only cover some users in the cell, in order to ensure that all users in the cell can be covered, time-division beam switching is usually required.

由于两个相邻时刻的波束切换对应一段切换时间，在采用该波束切换技术时，为实现从一个传输时刻的波束到下一个传输时刻的波束的切换，在帧结构设计时会考虑预留波束切换时间。Since the beam switching at two adjacent moments corresponds to a switching time, when the beam switching technique is adopted, in order to realize the switching of the beam from one transmission time to the next transmission time, the reserved beam is considered in the frame structure design. Switch time.

如图1所示，图1是现有的一种数据帧结构。在图1中，符号1上对应的波束为B1，符号2和符号3上对应的波束为B2。由于符号1和符号2上的波束不同，因此在符号1的尾部预留波束B1切换到B2所需的切换时间。而符号2和符号3的波束相同，因此在符号2的尾部不需预留切换时间。在现有的数据帧结构中，由于波束切换集中在一个符号内完成，因此在有波束切换的符号内用于数据传输的有效时间长度大大减小，这增加了这些符号的开销和硬件实现的复杂度。As shown in FIG. 1, FIG. 1 is a conventional data frame structure. In FIG. 1, the corresponding beam on symbol 1 is B1, and the corresponding beam on symbol 2 and symbol 3 is B2. Since the beams on symbol 1 and symbol 2 are different, the switching time required for beam B1 to switch to B2 is reserved at the tail of symbol 1. The beams of symbol 2 and symbol 3 are the same, so there is no need to reserve the switching time at the end of symbol 2. In the existing data frame structure, since the beam switching is concentrated in one symbol, the effective time length for data transmission in the symbol with beam switching is greatly reduced, which increases the overhead and hardware implementation of these symbols. the complexity.

本文中，无线时间窗指的是数据发送设备与其他通信设备通信时数据发送设备进行数据发送的时间起点和时间终点之间的时间段，其中，该数据发送设别可以是基站，在此不作限制。无线时间窗包括多个连续的时间单元，其中所述时间单元的长度大于等于一次数据传输所需要的时间。例如，目前一次数据传输的最小时间长度为一个符号，所述时间单元可以是一个或至少两个符号、一个或至少两个时隙、一个或至少两个子帧、一个或至少两个帧等等。Herein, the wireless time window refers to a time period between a time start point and a time end point at which the data transmitting device performs data transmission when the data transmitting device communicates with other communication devices, wherein the data transmission device may be a base station, and is not used herein. limit. The wireless time window includes a plurality of consecutive time units, wherein the length of the time unit is greater than or equal to the time required for one data transmission. For example, the minimum time length of a current data transmission is one symbol, and the time unit may be one or at least two symbols, one or at least two slots, one or at least two subframes, one or at least two frames, and the like. .

本实施例中，由于数据发送设备发出的信号对应的波束较窄，无法覆盖小区内的全部目标用户，因此数据发送设备需要进行时分的波束切换。其中，该波束切换发生在切换时间单元对内，该切换时间单元对为无线时间窗内相连的两个时间单元。In this embodiment, since the signal corresponding to the signal sent by the data transmitting device is narrow and cannot cover all target users in the cell, the data transmitting device needs to perform time-division beam switching. The beam switching occurs within a pair of switching time units that are two time units connected within a wireless time window.

为描述方便，本文中称切换时间单元对所包括的两个相连的时间单元为第一时间单元和第二时间单元。需注意的是，切换时间单元对中的两个时间单元不一定是在同一个时隙或同一个子帧或同一个帧中。具体的，本实施例中，无线时间窗包括多个连续的无线时间子窗，所述无线时间子窗包括多个连续的时间单元。所述切换时间单元对的两个时间单元分别位于相邻的两个所述无线时间子窗中。例如，每一个无线时间子窗为一个帧，切换时间单元对的两个时间单元分别位于相邻的两个帧里。或者，每一个无线时间子窗为一个子帧，切换时间单元对的两个时间单元分别位于相邻的两个子帧里。或者，每一个无线时间子窗为一个时隙，切换时间单元对的两个时间单元分别位于相邻的两个时隙里。For convenience of description, the two connected time units included in the switching time unit pair are referred to herein as the first time unit and the second time unit. It should be noted that the two time units in the pair of switching time units are not necessarily in the same time slot or in the same subframe or the same frame. Specifically, in this embodiment, the wireless time window includes a plurality of consecutive wireless time sub-windows, and the wireless time sub-window includes a plurality of consecutive time units. The two time units of the pair of switching time units are respectively located in two adjacent wireless time sub-windows. For example, each wireless time sub-window is one frame, and two time units of the switching time unit pair are respectively located in two adjacent frames. Alternatively, each wireless time sub-window is one subframe, and two time units of the switching time unit pair are respectively located in two adjacent subframes. Alternatively, each wireless time sub-window is one time slot, and two time units of the switching time unit pair are respectively located in two adjacent time slots.

当然，切换时间单元对中的两个时间单元也可以位于同一个无线时间子窗内，在此不作限制。Of course, the two time units in the pair of switching time units can also be located in the same wireless time sub-window. There is no limit here.

所述切换时间单元对中设置有第一时间段和第二时间段，其中第一时间段包括第一时间单元的至少一部分，第二时间段包括第二时间单元的至少一部分；所述第一时间段和所述第二时间段连续，且所述第一时间段和所述第二时间段构成切换时间段。数据发送设备进行波束切换发生在该切换时间段内。一个无线时间窗内所包含的切换时间单元对的数量根据实际中数据发送设备进行波束切换的次数来定，在此不作限制。而且，一个无线时间窗内各切换时间单元对可以是连续的，也可以是非连续的，在此不作限制。The switching time unit pair is provided with a first time period and a second time period, wherein the first time period includes at least a portion of the first time unit, and the second time period includes at least a portion of the second time unit; The time period and the second time period are continuous, and the first time period and the second time period constitute a switching time period. The data transmitting device performs beam switching within the switching period. The number of switching time unit pairs included in a wireless time window is determined according to the number of times the data transmitting device performs beam switching in the actual, and is not limited herein. Moreover, the pair of switching time units in a wireless time window may be continuous or non-continuous, and is not limited herein.

需注意的是，第一时间段和第二时间段的长度取决于实际中波束切换的历时长度，其中，切换时间段的长度大于或者等于波束切换的历时长度。实际应用中，帧结构设计中预留的所述切换时间段的长度通常为大于实际中可能的最大波束切换历时长度的一个值。第一时间段可以包括所述切换时间单元对中第一时间单元的部分或者全部，第二时间段可以包括所述切换时间单元对中第二间单元的部分或者全部，在此不作限制。例如，所述切换时间单元对中的每个时间单元为符号，所述第一时间段和所述第二时间段分别为所述符号中的至少一个部分。或者，所述切换时间单元对中的每个时间单元为时隙，所述第一时间段和所述第二时间段分别为所述时隙中的至少一个符号。或者，所述切换时间单元对中的每个时间单元为子帧，所述第一时间段和所述第二时间段分别为所述时隙中的至少一个符号或时隙。或者，所述切换时间单元对中的每个时间单元为帧，所述第一时间段和所述第二时间段分别为所述时隙中的至少一个符号、时隙或子帧。It should be noted that the lengths of the first time period and the second time period depend on the duration of the actual beam switching, wherein the length of the switching time period is greater than or equal to the duration of the beam switching. In practical applications, the length of the switching period reserved in the frame structure design is usually a value larger than the length of the maximum possible beam switching duration in practice. The first time period may include part or all of the first time unit of the pair of switching time units, and the second time period may include part or all of the second unit of the pair of switching time units, which is not limited herein. For example, each time unit of the pair of switching time units is a symbol, and the first time period and the second time period are respectively at least one of the symbols. Or each time unit of the pair of switching time units is a time slot, and the first time period and the second time period are respectively at least one symbol in the time slot. Or each time unit of the pair of switching time units is a subframe, and the first time period and the second time period are respectively at least one symbol or time slot in the time slot. Or each time unit in the pair of switching time units is a frame, and the first time period and the second time period are respectively at least one symbol, time slot or subframe in the time slot.

本实施例中，无线时间窗中切换时间单元对的配置信息可以包括所述切换时间单元对在所述无线时间窗中的位置以及所述切换时间段在所述切换时间单元对中的位置。该切换时间段在所述切换时间单元对中的位置可以包括所述第一时间段在所述切换时间单元对中的第一时间单元中的长度和所述第二时间段在所述切换时间单元对中的第二时间单元中的长度，或者包括所述第一时间段在所述切换时间单元对中的第一时间单元中的起点和第二时间段在所述切换时间单元对中的第二时间单元中的终点等等。切换时间单元对的配置信息还可以包括其他信息，在此不作限制，只要使得数据发送设备可以根据该切换时间单元对的配置信息至少确定进行每次波束切换的位置，也即每次波束切换的时间起点和时间终点即可。实际运用中，无线时间窗中切换时间单元对的配置信息被预先存储在数据发送设备中。发送模块202在发送数据之前，处理模块201确定该数据发送的无线时间窗内切换时间单元对的配置信息。In this embodiment, the configuration information of the switching time unit pair in the wireless time window may include a location of the switching time unit to the wireless time window and a location of the switching time period in the pair of switching time units. The location of the handover time period in the pair of handover time units may include a length of the first time period in a first time unit of the pair of handover time units and the second time period at the handover time a length in the second time unit of the pair of cells, or a start point and a second time period of the first time unit in the pair of switching time unit pairs in the pair of switching time units The end point in the second time unit, and so on. The configuration information of the switching time unit pair may further include other information, which is not limited herein, as long as the data transmitting device can be switched according to the switch. The configuration information of the time unit pair determines at least the position at which each beam switching is performed, that is, the time start point and the time end point of each beam switching. In actual use, the configuration information of the switching time unit pair in the wireless time window is pre-stored in the data transmitting device. Before the sending module 202 sends the data, the processing module 201 determines the configuration information of the pair of switching time units in the wireless time window of the data transmission.

发送模块202用于在所述无线时间窗内发送数据；所述处理模块201还用于根据所述切换时间单元对的配置信息在所述切换时间单元对的切换时间段内进行波束切换。The sending module 202 is configured to send data in the wireless time window. The processing module 201 is further configured to perform beam switching in a switching time period of the pair of switching time units according to the configuration information of the pair of switching time units.

处理模块201确定无线时间窗中切换时间单元对的配置信息后，在该无线时间窗内发送数据。其中，在该无线时间窗中切换时间单元对中的切换时间段内停止数据发送，进行波束切换。在无线时间窗内除切换时间单元对以外的其他时间单元内时，发送模块202发送数据，可以有多种模式，此为现有技术，在此不再赘述。After the processing module 201 determines the configuration information of the switching time unit pair in the wireless time window, the data is transmitted in the wireless time window. The data transmission is stopped during the switching time period of the switching time unit pair in the wireless time window, and beam switching is performed. The transmitting module 202 sends data in a time unit other than the switching time unit in the wireless time window. The data may be in a plurality of modes. This is a prior art and is not described here.

本实施例中，数据发送设备通过在相邻的两个时间单元中设置相连的第一时间段和第二时间段，并在第一时间段和第二时间段组成的切换时间段内进行波束切换，这样，相比背景技术中仅集中在一个符号中波束切换，本实施例中用于波束切换的切换时间段可支持的最大切换时间的长度，是大于一个符号可支持的最大切换时间长度的，且切换时间段由相邻两个时间单元内的第一时间段和第二时间段相连组成，因此既可以放宽波束切换对硬件的实现要求，降低波束切换的硬件实现难度，又可以降低进行波束切换的时间单元的开销和波束切换对数据传输的影响。In this embodiment, the data transmitting device sets the connected first time period and the second time period in two adjacent time units, and performs the beam in the switching time period composed of the first time period and the second time period. Switching, so that the length of the maximum switching time that can be supported by the switching period for beam switching in this embodiment is greater than the maximum switching time length that can be supported by one symbol, compared to the beam switching in only one symbol in the background. And the switching time period is composed of the first time period and the second time period in the adjacent two time units, so that the implementation requirements of the hardware of the beam switching can be relaxed, the hardware implementation difficulty of the beam switching can be reduced, and the hardware can be reduced. The overhead of the time unit for beam switching and the impact of beam switching on data transmission.

本实施例中的处理模块201可以是处理器，发送模块202可以是发送器，在此不作限制。The processing module 201 in this embodiment may be a processor, and the sending module 202 may be a transmitter, which is not limited herein.

可选的，本实施例中，所述发送模块202还用于将所述无线时间窗中的切换时间单元对的配置信息发送至数据接收端，以便所述数据接收端根据所述配置信息对所述数据进行接收。Optionally, in this embodiment, the sending module 202 is further configured to send configuration information of the switching time unit pair in the wireless time window to the data receiving end, so that the data receiving end is configured according to the configuration information. The data is received.

优选的，本实施例中，切换时间单元对中的第一时间段和第二时间段的长度相同，这样可以减小无线时间窗中切换时间单元对的配置信令开销。Preferably, in this embodiment, the lengths of the first time period and the second time period of the pair of switching time units are the same, so that the configuration signaling overhead of the switching time unit pair in the wireless time window can be reduced.

本实施例中，数据发送设备在无线时间窗内进行数据发送有多种方式。例如，如图3所示，图3为本发明的数据发送设备中无线时间窗的一种实施例的结构示意图。在无线时间窗内除切换时间单元对31以外的其他时间单元32中，每个时间单元32包括循环前缀部分321(图中的方框中的阴影部分)和数据部分322(图中的方框中的空白部分)。也即数据发送设备在无线时间窗的每个时间单元内发送一个OFDM(英文全称：Orthogonal Frequency Division Multiplexing，中文：正交频分复用)符号的循环前缀和有效数据。在时间单元32的循环前缀部分321，数据发送设备发送OFDM符号的循环前缀；在时间单元32的数据部分322，数据发送设备发送OFDM符号的有效数据。In this embodiment, the data transmitting device performs data transmission in a wireless time window in various manners. For example, as shown in FIG. 3, FIG. 3 is an embodiment of a wireless time window in a data transmitting device of the present invention. Schematic. In time units 32 other than the switching time unit pair 31 in the wireless time window, each time unit 32 includes a cyclic prefix portion 321 (shaded portion in the block in the figure) and a data portion 322 (box in the figure) The blank part in the). That is, the data transmitting device transmits a cyclic prefix and valid data of an OFDM (Orthogonal Frequency Division Multiplexing) symbol in each time unit of the wireless time window. At the cyclic prefix portion 321 of the time unit 32, the data transmitting device transmits a cyclic prefix of the OFDM symbol; at the data portion 322 of the time unit 32, the data transmitting device transmits valid data of the OFDM symbol.

在无线时间窗的切换时间单元对31的两个时间单元311和312中，时间单元311包括数据部分3111(图中的方框中的空白部分)和第一时间段3112(图中的方框中的斜线部分)，时间单元312包括第二时间段3121(图中的方框中的斜线部分)和数据部分3122(图中的方框中的空白部分)。在时间单元311的数据部分3111，数据发送设备发送OFDM符号的有效数据；在时间单元311的第一时间段3112和时间单元312的第二时间段3121，数据发送设备进行波束切换；在时间单元312的数据部分3122，数据发送设备发送OFDM符号的有效数据。In the two

time units

311 and 312 of the switching time unit pair 31 of the wireless time window, the time unit 311 includes a data portion 3111 (a blank portion in a block in the figure) and a first time period 3112 (a box in the figure) The timeline portion 312 includes a second time period 3121 (hatched portion in the block in the figure) and a data portion 3122 (blank portion in the box in the figure). In the data portion 3111 of the time unit 311, the data transmitting device transmits valid data of the OFDM symbol; in the first time period 3112 of the time unit 311 and the second time period 3121 of the time unit 312, the data transmitting device performs beam switching; in the time unit Data portion 3122 of 312, the data transmitting device transmits valid data for the OFDM symbol.

实际运用中，无线时间窗的切换时间单元对有多种图样形式。如图4所示，图4为本发明的数据发送设备中无线时间窗的另一种实施例的结构示意图。与图2所示无线时间窗不同的是，本实施例中，切换时间单元对41的两个时间单元411和412中，时间单元411包括循环前缀部分4111、数据部分4112和第一时间段4113，时间单元412包括第二时间段4121、循环前缀部分4122和数据部分4123。In practical use, the switching time unit of the wireless time window has multiple patterns. As shown in FIG. 4, FIG. 4 is a schematic structural diagram of another embodiment of a wireless time window in a data transmitting device according to the present invention. Different from the wireless time window shown in FIG. 2, in the present embodiment, among the two

time units

411 and 412 of the switching time unit pair 41, the time unit 411 includes a cyclic prefix portion 4111, a data portion 4112, and a first time period 4113. The time unit 412 includes a second time period 4121, a cyclic prefix portion 4122, and a data portion 4123.

在时间单元411的循环前缀部分4111，数据发送设备发送OFDM符号的循环前缀；在时间单元411的数据部分4112，数据发送设备发送OFDM符号的有效数据；在时间单元411的第一时间段4113和时间单元412的第二时间段4121，数据发送设备进行波束切换；在时间单元412的循环前缀部分4122，数据发送设备发送OFDM符号的循环前缀；在时间单元412的数据部分4123，数据发送设备发送OFDM符号的有效数据。In the cyclic prefix portion 4111 of the time unit 411, the data transmitting device transmits a cyclic prefix of the OFDM symbol; in the data portion 4112 of the time unit 411, the data transmitting device transmits valid data of the OFDM symbol; in the first time period 4113 of the time unit 411 and The second time period 4121 of the time unit 412, the data transmitting device performs beam switching; in the cyclic prefix portion 4122 of the time unit 412, the data transmitting device transmits a cyclic prefix of the OFDM symbol; in the data portion 4123 of the time unit 412, the data transmitting device transmits Valid data for OFDM symbols.

需注意的是，本实施例中，由于时间单元411中设置有第一时间段4113，时间单元412中设置有第二时间段4121，那么切换时间单元41对中每个时间单元的循环前缀部分和数据部分的长度之和小于或等于无线时间窗中除切换时间单元对41以外的其他时间单元42中的循环前缀部分和数据部分的长度之和。It should be noted that, in this embodiment, since the first time period 4113 is set in the time unit 411 and the second time period 4121 is set in the time unit 412, the time unit 41 is switched in each time. The sum of the cyclic prefix portion of the unit and the length of the data portion is less than or equal to the sum of the cyclic prefix portion and the length of the data portion in the time unit 42 other than the switching time unit pair 41 in the wireless time window.

具体的，可以是切换时间单元对41中每个时间单元的循环前缀部分的长度等于时间单元42的循环前缀部分的长度，使得所述切换时间单元对41中每个时间单元的数据部分的长度小于时间单元42的数据部分的长度。Specifically, it may be that the length of the cyclic prefix portion of each time unit in the switching time unit pair 41 is equal to the length of the cyclic prefix portion of the time unit 42 such that the length of the data portion of each time unit in the switching time unit pair 41 Less than the length of the data portion of time unit 42.

或者，优选的，切换时间单元对41中每个时间单元的循环前缀部分的长度小于时间单元42的循环前缀部分的长度，使得所述切换时间单元对41中每个时间单元的数据部分的长度等于时间单元42的数据部分的长度。这样可以使得无线时间窗内各时间单元内的有效数据的长度一致。也即切换时间单元对41内的第一时间单元中尾部原本用于数据传输的部分时长被改用为用于波束切换，由于循环前缀内的数据是OFDM符号的尾部的数据的复制，该改为波束切换的部分数据由循环前缀内的至少一部分数据补上，使得第一时间单元内的数据部分的长度等于时间单元42的数据部分的长度，而循环前缀的其余部分数据形成第一时间单元的循环前缀部分；而第二时间单元中原本用于循环前缀的时长的至少一部分被改为用于波束切换，这样波束切换不占用数据传输的时长，使得第二时间单元内的数据部分的长度等于时间单元42的数据部分的长度，而循环前缀的其余部分数据形成第二时间单元的循环前缀部分。这样，可以方便在设置切换时间单元对的配置信息时在波束切换的预留时间和抗多径时延扩展间做灵活的折中，且波束切换时间和抗多径时延扩展时间无缝结合，可以最大程度减少无线时间窗中波束切换时间所带来的开销。而且，在切换时间单元对41由无线时间窗中无线时间子窗的第一个时间单元和第二个时间单元组成的情况下，当控制格式指示信道(例如PCFICH(Physical Control Format Indication Channel，物理控制格式指示信道))需在第一个时间单元传输时，所述控制格式指示信道的传输不会受到切换时间的影响，从而保证了所述控制格式指示信道性能的鲁棒性。为方便理解，下面结合图12和图13进行解释描述。Alternatively, preferably, the length of the cyclic prefix portion of each time unit in the switching time unit pair 41 is smaller than the length of the cyclic prefix portion of the time unit 42, such that the length of the data portion of each time unit in the switching time unit pair 41 Equal to the length of the data portion of time unit 42. This makes it possible to match the length of the valid data in each time unit in the wireless time window. That is, the part of the time in the first time unit in the switching time unit pair 41 originally used for data transmission is changed to be used for beam switching, since the data in the cyclic prefix is the copy of the data of the tail of the OFDM symbol, the change The partial data for beam switching is complemented by at least a portion of the data within the cyclic prefix such that the length of the data portion within the first time unit is equal to the length of the data portion of time unit 42, and the remaining portion of the cyclic prefix forms the first time unit The cyclic prefix portion; and at least a portion of the duration of the second time unit originally used for the cyclic prefix is changed to be used for beam switching, such that the beam switching does not occupy the duration of the data transmission, such that the length of the data portion within the second time unit Equal to the length of the data portion of time unit 42, and the remainder of the cyclic prefix data forms the cyclic prefix portion of the second time unit. In this way, it is convenient to make a flexible compromise between the reservation time of the beam switching and the anti-multipath delay extension when setting the configuration information of the switching time unit pair, and the beam switching time and the anti-multipath delay extension time are seamlessly combined. The overhead caused by the beam switching time in the wireless time window can be minimized. Moreover, in the case where the handover time unit pair 41 is composed of the first time unit and the second time unit of the radio time sub-window in the radio time window, when the control format indication channel (for example, PCFICH (Physical Control Format Indication Channel) The control format indication channel)) when the first time unit is to be transmitted, the control format indicates that the transmission of the channel is not affected by the switching time, thereby ensuring that the control format indicates the robustness of the channel performance. For ease of understanding, the explanation will be explained below with reference to FIGS. 12 and 13.

在图12和图13中，无线时间子窗为LTE标准中的无线子帧，时间单元为一个OFDM符号。如图12和图13所示，图12和图13分别为LTE标准中 TDD特殊子帧的两种实施例的结构示意图。图中，DL为下行，UL为上行，GP为上下行转换的时间间隙。在图12所示的特殊子帧的第一个OFDM符号121中，循环前缀部分的长度为零，波束切换所占用的时长(图中用斜线部分表示)等于除切换时间单元对以外的其他时间单元内的循环前缀部分的时长，即无线时间子窗中各时间单元的数据部分的长度相等，使得所述特殊子帧中第一个OFDM符号的数据传输不会因为切换时间的设置而受到影响，从而能保证当一些控制格式指示信道在所述特殊子帧的第一个OFDM符号内传输时，性能不会受影响。In FIG. 12 and FIG. 13, the radio time sub-window is a radio subframe in the LTE standard, and the time unit is one OFDM symbol. As shown in FIG. 12 and FIG. 13, FIG. 12 and FIG. 13 are respectively in the LTE standard. Schematic diagram of two embodiments of a TDD special subframe. In the figure, DL is downlink, UL is uplink, and GP is the time gap of uplink and downlink conversion. In the first OFDM symbol 121 of the special subframe shown in FIG. 12, the length of the cyclic prefix portion is zero, and the duration occupied by the beam switching (indicated by a hatched portion in the figure) is equal to other than the pair of switching time units. The duration of the cyclic prefix portion in the time unit, that is, the length of the data portion of each time unit in the wireless time sub-window is equal, so that the data transmission of the first OFDM symbol in the special subframe is not affected by the setting of the switching time. The effect is such that performance is not affected when some of the control format indicator channels are transmitted within the first OFDM symbol of the special subframe.

而在图13所示的特殊子帧的第一个OFDM符号131中的循环前缀部分(图中用阴影部分表示)的长度不为零，波束切换所占用的时长(图中用斜线部分表示)与循环前缀部分的长度的和大于除切换时间单元对以外的其他时间单元内的循环前缀部分的时长，即切换时间单元对中的时间单元的数据部分的长度小于其他时间单元的数据部分的长度，从而该第一个OFDM符号的数据传输将受到切换时间设置的影响，也即第一个OFDM符号的数据传输随切换时间和循环前缀的设置而变化。The length of the cyclic prefix portion (shown by the shaded portion in the first OFDM symbol 131 of the special subframe shown in FIG. 13 is not zero, and the length of time taken by the beam switching (indicated by a hatched portion in the figure) And the length of the cyclic prefix portion is greater than the duration of the cyclic prefix portion in the time unit other than the switching time unit pair, that is, the length of the data portion of the time unit in the switching time unit pair is smaller than the data portion of the other time unit The length, and thus the data transmission of the first OFDM symbol, will be affected by the switching time setting, ie the data transmission of the first OFDM symbol varies with the switching time and the setting of the cyclic prefix.

在其他类型的特殊子帧或其他普通子帧类型(如全部由下行符号组成的下行子帧或全部由上行符号组成的上行子帧)中，所述子帧的第一个OFDM符号中的切换时间设置可与上例特殊子帧中的切换时间设置相同。In other types of special subframes or other common subframe types (such as all downlink subframes consisting of downlink symbols or all uplink subframes consisting of uplink symbols), switching in the first OFDM symbol of the subframe The time setting can be the same as the switching time setting in the special sub-frame of the above example.

本实施例中，由于切换时间单元对41内的时间单元中原本用于循环前缀的部分时长被改为用于波束切换，那么在设计无线时间窗时可以将每个OFDM符号中的循环前缀设计得稍长一些。例如，时间单元42中的循环前缀部分421的长度为1.667us。时间单元411和412中的循环前缀部分的长度均为1us，第一时间段4113和第二时间段4121均为0.667us，从而使得时间单元42中的数据部分的长度和时间单元411、412中数据部分的长度相同，且每个时间单元中均有循环前缀部分，从而可保证每个时间单元内的数据传输的抗多径干扰效果。In this embodiment, since the partial duration originally used for the cyclic prefix in the time unit in the switching time unit pair 41 is changed to be used for beam switching, the cyclic prefix design in each OFDM symbol can be designed when designing the wireless time window. It will be a little longer. For example, the length of the cyclic prefix portion 421 in the time unit 42 is 1.667us. The lengths of the cyclic prefix portions in the

time units

411 and 412 are both 1 us, and the first time period 4113 and the second time period 4121 are both 0.667 us, thereby causing the length of the data portion in the time unit 42 and the

time units

411, 412. The data portion has the same length and a cyclic prefix portion in each time unit, thereby ensuring the anti-multipath interference effect of data transmission in each time unit.

或者，也可以是切换时间单元对41中每个时间单元的循环前缀部分的长度小于时间单元42的循环前缀部分的长度，且切换时间单元对41中每个时间单元的数据部分的长度也小于时间单元42的数据部分的长度。 Alternatively, it may also be that the length of the cyclic prefix portion of each time unit in the switching time unit pair 41 is smaller than the length of the cyclic prefix portion of the time unit 42, and the length of the data portion of each time unit in the switching time unit pair 41 is also smaller than The length of the data portion of time unit 42.

或者，还可以是切换时间单元对41中其中一个时间单元包括循环前缀部分而另一个时间单元不包括循环前缀部分，在此不作限制。Alternatively, it may be that one of the time units of the switching time unit 41 includes a cyclic prefix part and the other time unit does not include a cyclic prefix part, which is not limited herein.

上面以数据发送设备在无线时间窗中的一个时间单元内发送一个OFDM符号为例对无线时间窗中的各时间单元的图样进行举例说明。当然，实际运用中，数据发送设备在无线时间窗的每个时间单元内还可以有其他的发送数据的模式，在此不作限制。The pattern of each time unit in the wireless time window is exemplified above by taking the data transmitting device transmitting one OFDM symbol in one time unit in the wireless time window as an example. Of course, in actual use, the data transmitting device may have other modes for transmitting data in each time unit of the wireless time window, which is not limited herein.
