Description

GC-PDCCH transmission method and equipment

Technical field

本申请实施例涉及通信领域，尤其涉及一种组公共(Group Common，GC)物理下行控制信道(Physical Downlink Control Channel，PDCCH)(简称GC-PDCCH)的传输方法和设备。The embodiments of the application relate to the field of communications, and in particular to a transmission method and device for a Group Common (GC) Physical Downlink Control Channel (PDCCH) (GC-PDCCH for short).

Background technique

新空口(New Radio，NR)通信系统中引入了GC-PDCCH这种新的控制信道，GC-PDCCH主要用于网络设备向一组终端设备指示下行控制信息，例如时隙格式信息(Slot Format Information，SFI)，SFI用于指示当前时隙和/或后续一个或多个时隙的时隙格式。GC-PDCCH is a new control channel introduced in the New Radio (NR) communication system. GC-PDCCH is mainly used by network equipment to indicate downlink control information to a group of terminal equipment, such as slot format information (Slot Format Information). , SFI), SFI is used to indicate the time slot format of the current time slot and/or one or more subsequent time slots.

在NR的非授权通信系统中，当网络设备获取信道后可持续传输一定时间，即信道占用时间(Channel Occupancy Time，COT)，并可以共享该COT给它连接的终端设备进行传输，以此，终端设备可以减少某些不必要的操作(例如PDCCH监测)来节约功率消耗。In the NR unlicensed communication system, when a network device acquires a channel, it can continue to transmit for a certain period of time, that is, Channel Occupancy Time (COT), and can share the COT to the terminal device it is connected to for transmission. In this way, The terminal device can reduce some unnecessary operations (such as PDCCH monitoring) to save power consumption.

相关技术中提供一种解决方案，使用GC-PDCCH中SFI指示的时隙(slot)个数来指示COT长度。然而，这与NR Rel15中要求SFI指示的时隙个数要大于等于配置的SFI的监测周期的要求矛盾；同时，COT可以在时隙的中间位置开始，也可以时隙的中间位置结束，但是SFI指示的时隙个数一定是时隙长度的整数倍，不能够实现COT的有效指示。A solution is provided in the related art, which uses the number of slots indicated by the SFI in the GC-PDCCH to indicate the COT length. However, this contradicts the requirement in NR Rel15 that the number of time slots indicated by the SFI should be greater than or equal to the configured monitoring period of the SFI; at the same time, COT can start in the middle of the time slot or end in the middle of the time slot, but The number of time slots indicated by the SFI must be an integer multiple of the length of the time slot, and COT cannot be effectively indicated.

因此，有必要提出一种技术方案，以对网络设备获取信道的COT进行有效指示。Therefore, it is necessary to propose a technical solution to effectively instruct the network equipment to obtain the COT of the channel.

The method can be executed by a terminal device. In other words, the method can be executed by software or hardware installed on the terminal device. Including the following steps:

S102：接收GC-PDCCH，该GC-PDCCH包括SFI信息，该SFI信息用于指示一个或多个时隙的时隙格式组合。S102: Receive a GC-PDCCH, where the GC-PDCCH includes SFI information, and the SFI information is used to indicate a time slot format combination of one or more time slots.

在该实施例之前，网络设备可以为终端设备进行GC-PDCCH配置，例如，配置GC-PDCCH的周期、时频位置等，这样，终端设备即可根据上述配置接收GC-PDCCH。Before this embodiment, the network device can perform GC-PDCCH configuration for the terminal device, for example, configure the period and time-frequency position of the GC-PDCCH, so that the terminal device can receive the GC-PDCCH according to the above configuration.

该实施例中，网络设备可以利用非授权频谱发送GC-PDCCH；也可以利用授权频谱，如主载波来发送GC-PDCCH，以提高GC-PDCCH传输的可靠性。In this embodiment, the network device can use the unlicensed spectrum to send the GC-PDCCH; it can also use the licensed spectrum, such as the primary carrier, to send the GC-PDCCH, so as to improve the reliability of GC-PDCCH transmission.

终端设备接收到的GC-PDCCH包括有SFI信息(SFI信息还可以简称为SFI)，该SFI信息用于指示一个或多个时隙的时隙格式组合(slot format combination)。The GC-PDCCH received by the terminal device includes SFI information (SFI information may also be referred to as SFI for short), and the SFI information is used to indicate a slot format combination of one or more time slots.

需要说明的是，本说明书实施例中提到的SFI信息用于指示一个或多个时隙的时隙格式组合，或者可以称作是SFI信息用于指示时隙格式组合，该时隙格式组合用于指示一个或多个时隙的时隙格式。It should be noted that the SFI information mentioned in the embodiment of this specification is used to indicate the time slot format combination of one or more time slots, or it can be called SFI information used to indicate the time slot format combination, and the time slot format combination Used to indicate the time slot format of one or more time slots.

在该实施例之前，网络设备可以通过无线资源控制(Radio Resource Control，RRC)信令为终端设备配置多个(小于或等于512)时隙格式组合，每个时隙格式组合可以指示1-256个时隙的时隙格式。需要说明的是，该处虽然称作是时隙格式组合，实际上，时隙格式组合可以仅包括一个时隙。Before this embodiment, the network device can configure multiple (less than or equal to 512) slot format combinations for the terminal device through Radio Resource Control (RRC) signaling, and each slot format combination can indicate 1-256 The slot format of each slot. It should be noted that although this is called a time slot format combination, in fact, the time slot format combination may include only one time slot.

对于本说明书各个实施例中提到的时隙格式，如表1所示，表1示意性地显示出部分时隙的时隙格式。For the time slot format mentioned in the various embodiments of this specification, as shown in Table 1, Table 1 schematically shows the time slot format of some time slots.

表1Table 1

在表1中，最左侧的一列为时隙格式索引(index)，对于单时隙，NR Rel15支持的最大时隙格式数为256个，包括指示时隙的每个符号为下行(Downlink，D)，上行(Uplink，U)或者灵活(Flexible，F)。In Table 1, the leftmost column is the time slot format index. For a single time slot, the maximum number of time slot formats supported by NR Rel15 is 256, including indicating that each symbol of the time slot is Downlink (Downlink, D), Uplink (Uplink, U) or Flexible (Flexible, F).

在表1中，时隙格式索引56至254为预留时隙格式；时隙格式索引 255为没有指示符号动态上下行状态的时隙格式。In Table 1, time slot format indexes 56 to 254 are reserved time slot formats; time slot format index 255 is a time slot format that does not indicate the dynamic uplink and downlink status of the symbol.

基于表1，SFI信息指示一个或多个时隙的时隙格式组合时，具体可以指示一个或多个时隙的时隙格式索引。Based on Table 1, when the SFI information indicates the time slot format combination of one or more time slots, it may specifically indicate the time slot format index of one or more time slots.

在实际应用过程中，终端设备通常配置有多个时隙格式组合，每个时隙格式组合也可以包括有索引，因此，SFI信息也可以仅仅指示时隙格式组合的索引。In the actual application process, the terminal equipment is usually configured with multiple time slot format combinations, and each time slot format combination may also include an index. Therefore, the SFI information may also only indicate the index of the time slot format combination.

在一个例子中，SFI指示的时隙格式组合为(0，4，1，18)，通过表1可知，该时隙格式组合中的4个时隙的时隙格式为(DDDDDDDDDDD，DDDDDDDDDFF，UUUUUUUUUUU，DDDFFFFFFFF)。In an example, the time slot format combination indicated by SFI is (0, 4, 1, 18). As can be seen from Table 1, the time slot format of the 4 time slots in the time slot format combination is (DDDDDDDDDDD, DDDDDDDDDFF, UUUUUUUUUUU , DDDFFFFFFFF).

在另一个例子中，SFI指示的时隙格式组合为(0，4，1，18，255，255)，通过表1可知，该时隙格式组合中的6个时隙的时隙格式为(DDDDDDDDDDD，DDDDDDDDDFF，UUUUUUUUUUU，DDDFFFFFFFF，XXXXXXXXXXXXXX，XXXXXXXXXXXXXX)。In another example, the slot format combination indicated by SFI is (0, 4, 1, 18, 255, 255). From Table 1, it can be seen that the slot format of the 6 slots in the slot format combination is ( DDDDDDDDDDD, DDDDDDDDDDFF, UUUUUUUUUUU, DDDFFFFFFFF, XXXXXXXXXXXXXX, XXXXXXXXXXXXXX).

上述X可以表示没有指示符号动态上下行状态(后续类同)。实际上，全部为X的时隙格式还可以是表1中的时隙格式索引56-254中的任意一个。The above X may indicate the dynamic uplink and downlink status without an indicator symbol (the following is the same). In fact, the time slot format with all Xs can also be any one of the time slot format indexes 56-254 in Table 1.

S104：根据SFI信息指示的时隙格式组合，确定COT的结束位置。S104: Determine the end position of the COT according to the time slot format combination indicated by the SFI information.

该步骤中提到的COT，可以是网络设备获取信道后可持续传输的时间。COT的结束位置可以是该COT的结束符号的位置，包括但不限于结束符号所在的时隙的位置以及该结束符号在该时隙中的位置。The COT mentioned in this step may be the continuous transmission time after the network device acquires the channel. The end position of the COT may be the position of the end symbol of the COT, including but not limited to the position of the time slot where the end symbol is located and the position of the end symbol in the time slot.

图2是示出的网络设备的COT的时域示意图，横轴表示时间，纵轴(未显示)表示频率，斜线阴影区域表示表示GC-PDCCH所占的区域。图2中示意性地显示出3个GC-PDCCH。2 is a schematic diagram of the time domain of the COT of the network device shown. The horizontal axis represents time, the vertical axis (not shown) represents frequency, and the shaded area with diagonal lines represents the area occupied by GC-PDCCH. Figure 2 schematically shows three GC-PDCCHs.

图2中的COT横跨两个GC-PDCCH周期，通过第二个GC-PDCCH(即中间位置的GC-PDCCH)中的SFI，即可隐式指示COT的结束位置。通常，COT的开始位置不需指示。The COT in Figure 2 spans two GC-PDCCH cycles, and the end position of the COT can be implicitly indicated by the SFI in the second GC-PDCCH (ie, the GC-PDCCH in the middle position). Normally, the start position of COT does not need to be indicated.

在S104中提到的根据SFI信息指示的时隙格式组合，确定COT的结束位置，具体可以是根据SFI信息指示的时隙格式组合中的一个或多个时隙的时隙格式，确定COT的结束位置。In S104, according to the time slot format combination indicated by SFI information, the end position of COT is determined. Specifically, it can be determined according to the time slot format of one or more time slots in the time slot format combination indicated by SFI information. End position.

可选地，在一个实施例中，COT的结束符号是时隙格式组合的(一个或多个)时隙包括的全部符号中最后一个非灵活符号。该处提到的非灵活符号可以是上行符号，或者是下行符号。这样，S104具体可以是确定时隙格式组合中的时隙包括的全部符号中最后一个非灵活符号，将该最后一个非灵活符号作为是COT的结束位置。实际上，最后一个非灵活符号之后还可以包括一个或多个(连续的)灵活符号，这一个或多个连续的灵活符号可以称作是非COT(out of COT)指示。Optionally, in one embodiment, the end symbol of the COT is the last non-flexible symbol among all symbols included in the slot(s) of the slot format combination (one or more). The non-flexible symbols mentioned here can be uplink symbols or downlink symbols. In this way, S104 may specifically determine the last non-flexible symbol among all symbols included in the time slot in the time slot format combination, and use the last non-flexible symbol as the end position of the COT. In fact, one or more (continuous) flexible symbols may be included after the last non-flexible symbol, and these one or more continuous flexible symbols may be referred to as non-COT (out of COT) indications.

可选地，在一个实施例中，COT的结束符号是时隙格式组合的时隙中，最后一个非指定时隙格式的时隙的最后一个符号。这样，S104具体可以是确定时隙格式组合中的时隙中，最后一个非指定时隙格式的时隙的最后一个符号，将确定出的最后一个符号作为是COT的结束位置。实际上，最后一个非指定时隙格式的时隙之后还可以包括一个或多个(连续的)指定时隙格式的时隙，这一个或多个指定时隙格式的时隙可以称作是非COT(out of COT)指示。Optionally, in one embodiment, the end symbol of the COT is the last symbol of the last non-specified time slot format in the time slot of the time slot format combination. In this way, S104 may specifically determine the last symbol of the time slot of the last non-specified time slot format among the time slots in the time slot format combination, and use the determined last symbol as the end position of the COT. In fact, after the last non-specified time slot format, one or more (consecutive) time slots of the specified time slot format can be included after the last time slot. These one or more time slots of the specified time slot format can be called non-COT. (out of COT) instructions.

可选地，在一个实施例中，COT的结束符号是时隙格式组合的时隙中，最后一个非指定时隙格式的时隙的最后一个非灵活符号。这样，S104具体可以是确定时隙格式组合中的时隙中，最后一个非指定时隙格式的时隙的最后一个非灵活符号，将该最后一个非灵活符号作为是COT的结束位置。实际上，最后一个非指定时隙格式的时隙的最后一个非灵活符号之后还可以包括一个或多个(连续的)灵活符号；同时，最后一个非指定时隙格式的时隙之后还可以包括一个或多个(连续的)指定时隙格式的时隙，因此，上述一个或多个(连续的)灵活符号以及(最后的)一个或多个指定时隙格式的时隙可以称作是非COT(out of COT)指示。Optionally, in an embodiment, the end symbol of the COT is the last non-flexible symbol of the last non-specified time slot format in the time slot of the time slot format combination. In this way, S104 may specifically determine the last non-flexible symbol of the time slot of the last non-specified time slot format among the time slots in the time slot format combination, and use the last non-flexible symbol as the end position of the COT. In fact, after the last non-flexible symbol of the last non-specified time slot format, one or more (continuous) flexible symbols can be included after the last non-specified time slot format; at the same time, after the last non-specified time slot format, it can also include One or more (continuous) time slots in the specified time slot format, therefore, the above one or more (continuous) flexible symbols and (last) one or more time slots in the specified time slot format can be referred to as non-COT (out of COT) instructions.

本说明书各个实施例中提到的指定时隙格式包括下述至少之一：The specified time slot format mentioned in each embodiment of this specification includes at least one of the following:

1)预留时隙格式，见表1中的时隙格式索引56至254；1) The reserved time slot format, see the time slot format indexes 56 to 254 in Table 1;

2)没有指示符号动态上下行状态的时隙格式，见表1中的时隙格式索引255。2) There is no time slot format indicating the dynamic uplink and downlink status of the symbol. See the time slot format index 255 in Table 1.

这样，前文提到的非指定时隙格式，可以是表1中的指定时隙格式之外的时隙格式，例如，非指定时隙格式可以是表1中的时隙格式索引0至55中的任意一个。In this way, the non-designated time slot format mentioned above can be a time slot format other than the specified time slot format in Table 1. For example, the non-designated time slot format can be the time slot format index 0 to 55 in Table 1. Any one of.

需要说明的是，本说明书各个实施例中提到的时隙格式、指定时隙格式、非指定时隙格式等，还可以使用其它类似的术语来表示，例如，时隙格式还可以称作是时隙类型；指定时隙格式还可以称作是指定时隙类型、预设时隙类型或预设时隙格式等；非指定时隙格式还可以称作是非指定时隙类型、非预设时隙类型或称作是指定时隙格式之外的时隙格式等等。It should be noted that the time slot format, designated time slot format, non-designated time slot format, etc. mentioned in the various embodiments of this specification can also be represented by other similar terms. For example, the time slot format can also be referred to as Time slot type; designated time slot format can also be called designated time slot type, preset time slot type or preset time slot format, etc.; non-designated time slot format can also be called non-designated time slot type, non-preset time The slot type is also called a slot format other than the specified slot format, etc.

本申请实施例提供的GC-PDCCH的传输方法，终端设备接收到的GC-PDCCH包括SFI信息，该SFI信息用于指示一个或多个时隙的时隙格式组合，终端设备可以根据上述时隙格式组合确定COT的结束位置。According to the GC-PDCCH transmission method provided by the embodiment of this application, the GC-PDCCH received by the terminal equipment includes SFI information. The SFI information is used to indicate the time slot format combination of one or more time slots. The format combination determines the end position of the COT.

本申请实施例通过SFI指示的时隙格式组合隐式指示COT的结束位置，可以实现COT的有效指示。后续终端设备还可以共享该COT，更快地接入信道，以提高未授权频谱的利用效率；同时，终端设备可以减少某些不必要的操作(例如PDCCH监测)来节约功率消耗。The embodiment of the present application implicitly indicates the end position of the COT through the time slot format combination indicated by the SFI, which can realize the effective indication of the COT. Subsequent terminal devices can also share the COT and access channels faster to improve the utilization efficiency of unlicensed spectrum; at the same time, terminal devices can reduce some unnecessary operations (such as PDCCH monitoring) to save power consumption.
