一个实施例中，该方法还包括：In one embodiment, the method further includes:
如果确定在未知资源中检测PDCCH、且确定检测PDCCH的行为与终端切换为上行传输的行为冲突，则放弃检测PDCCH的行为。If it is determined that the PDCCH is detected in the unknown resource, and it is determined that the behavior of detecting the PDCCH conflicts with the behavior of the terminal switching to uplink transmission, the behavior of detecting the PDCCH is abandoned.

下面结合场景实施例对本发明进行描述。The present invention will be described below with reference to scenario embodiments.
TD-LTE采用等长的子帧(Sub-frame)结构：每个子帧1ms，包含两个0.5ms的时隙；10个子帧构成10ms的无线帧(Radio Frame)。TD-LTE引入了特殊子帧，特殊子帧由下行导频时隙(DwPTS,Downlink Pilot Time Slot)、保护间隔(GP,Guard Period)和上行导频时隙(UpPTS,Uplink Pilot Time Slot)三部分组成。现有LTE的特殊子帧配置如下表1：TD-LTE adopts an equal-length sub-frame (Sub-frame) structure: each sub-frame is 1 ms, including two 0.5-ms time slots; 10 sub-frames constitute a 10-ms radio frame (Radio Frame). TD-LTE introduces special subframes, which consist of three downlink pilot time slots (DwPTS, Downlink Pilot Time Slot), guard intervals (GP, Guard Period) and uplink pilot time slots (UpPTS, Uplink Pilot Time Slot). part composition. The special subframe configuration of the existing LTE is as follows in Table 1:
表1(TS36.211Table 4.2-1:Configuration of special subframe(lengths ofDwPTS/GP/UpPTS))Table 1 (TS36.211Table 4.2-1:Configuration of special subframe(lengths ofDwPTS/GP/UpPTS))
通过划分时间保护间隔(GP)作为代价，可以使得TD-LTE同一频段上同时实现上下行传输。为了满足不同覆盖场景的要求，在TD-LTE系统的一个无线帧中，上行传输普通子帧(U)、下行传输普通子帧(D)和特殊子帧(S)有7种不同的配置。通过调整上行和下行子帧数的配比，TD-LTE系统可以满足不同的上下行业务量比例的需求。现有LTE的上下行子帧配置如下表2：By dividing the time guard interval (GP) as a cost, the TD-LTE can realize simultaneous uplink and downlink transmission on the same frequency band. In order to meet the requirements of different coverage scenarios, in a radio frame of the TD-LTE system, there are 7 different configurations of uplink transmission ordinary subframe (U), downlink transmission ordinary subframe (D) and special subframe (S). By adjusting the ratio of the number of uplink and downlink subframes, the TD-LTE system can meet the needs of different uplink and downlink traffic ratios. The existing LTE uplink and downlink subframe configurations are as follows in Table 2:
表2(TS36.211Table 4.2-2:Uplink-downlink configurations)Table 2 (TS36.211Table 4.2-2:Uplink-downlink configurations)
通过以上描述可知，现有LTE的上下行资源配置是固定的，GP的设置相对僵化，不易调整，容易造成远端基站干扰等问题。As can be seen from the above description, the existing LTE uplink and downlink resource configuration is fixed, and the GP settings are relatively rigid, difficult to adjust, and easily cause problems such as remote base station interference.
在5G NR中，半静态帧结构中的未知资源能被SFI和/或DCI重新指示，比如指示为DL-only、UL-only、DL-domain或者UL-domain。对于未知资源来说，是否需要终端检测PDCCH有待解决。如图6所示，对于未知资源1，SFI指示了DL-domain的时隙，具体的，前面9个符号为下行资源，中间3个符号为未知资源，最后2个符号为上行资源。In 5G NR, unknown resources in the semi-static frame structure can be re-indicated by SFI and/or DCI, such as DL-only, UL-only, DL-domain or UL-domain. For unknown resources, it remains to be resolved whether the terminal needs to detect the PDCCH. As shown in FIG. 6 , for unknown resource 1, the SFI indicates the time slot of the DL-domain. Specifically, the first 9 symbols are downlink resources, the middle 3 symbols are unknown resources, and the last 2 symbols are uplink resources.
对于未知资源2，SFI指示了UL-domain的时隙，具体的，前面2个符号为下行资源，中间3个符号为未知资源，最后9个符号为上行资源。For unknown resource 2, the SFI indicates the time slot of the UL-domain. Specifically, the first two symbols are downlink resources, the middle three symbols are unknown resources, and the last nine symbols are uplink resources.
对于未知资源3，SFI指示了未知的时隙，具体的，前面2个符号是下行资源，中间10个符号是未知资源，最后2个符号为上行资源。进一步，对于未知资源3，可以用DCI进一步指示第3个到第7个符号也是下行资源，从而该时隙变成DL-domain的时隙。For unknown resource 3, the SFI indicates an unknown time slot. Specifically, the first 2 symbols are downlink resources, the middle 10 symbols are unknown resources, and the last 2 symbols are uplink resources. Further, for unknown resource 3, DCI can be used to further indicate that the 3rd to 7th symbols are also downlink resources, so that the time slot becomes a time slot of the DL-domain.
本发明实施例基站通过信令或者隐式的方式向UE指示是否在未知资源中检测PDCCH，从而可解决UE是否在未知资源中检测PDCCH的问题。In this embodiment of the present invention, the base station indicates to the UE whether to detect the PDCCH in the unknown resource through signaling or implicit means, so that the problem of whether the UE detects the PDCCH in the unknown resource can be solved.
基站可指示两种终端行为模式，终端根据这一指示确定自己的PDCCH检测行为。其中一种模式是在未知资源中检测PDCCH，另一种模式是在未知资源中不检测PDCCH。The base station can instruct two terminal behavior modes, and the terminal determines its own PDCCH detection behavior according to the instructions. One of the modes is to detect PDCCH in unknown resources, and the other mode is to not detect PDCCH in unknown resources.
本发明实施例中，若终端未收到所述基站指示的两种终端行为模式，则终端在未知资源中不检测PDCCH。In the embodiment of the present invention, if the terminal does not receive the two terminal behavior modes indicated by the base station, the terminal does not detect the PDCCH in the unknown resource.
这里，在小区专属信令配置完帧结构以后，UE还没有建立RRC连接之前，终端采用默认模式：不检测PDCCH。当RRC建立连接以后，终端可以收到UE专属的高层信令，从而确定帧结构，也可以收到指示检测PDCCH的信令或者指示不检测PDCCH的信令，从而确定终端行为。Here, after the frame structure is configured by the cell-specific signaling, and before the UE establishes the RRC connection, the terminal adopts the default mode: not detecting the PDCCH. After the RRC connection is established, the terminal can receive the UE-specific high-level signaling to determine the frame structure, and can also receive the signaling indicating to detect the PDCCH or the signaling indicating not to detect the PDCCH, so as to determine the terminal behavior.
其中，所述未知资源包括但不限于如下的一种或多种资源：Wherein, the unknown resources include but are not limited to one or more of the following resources:
小区专属高层信令中，未明确指示为下行/上行传输的资源；In the cell-specific high-level signaling, the resources are not explicitly indicated as downlink/uplink transmission;
用户专属高层信令中，未明确指示为下行/上行传输的资源；In the user-specific high-level signaling, the resource is not clearly indicated as the downlink/uplink transmission;
时隙格式指示(SFI)中指示的未知传输资源，或，未明确指示为下行/上行传输的资源。Unknown transmission resources indicated in the slot format indication (SFI), or resources not explicitly indicated for downlink/uplink transmission.
本发明一个实施例中，所述基站可以通过显式信令通知所述指示给终端，比如：RRC信令或者MAC CE等。In an embodiment of the present invention, the base station may notify the terminal of the indication through explicit signaling, such as RRC signaling or MAC CE.
本发明一个实施例中，所述基站发送的指示也可以是隐式的。具体的，In an embodiment of the present invention, the indication sent by the base station may also be implicit. specific,
a)终端根据是否是non-slot的调度确定是否检测PDCCH。这里，由于在未知资源中检测PDCCH(UL grant或者DL grant)，可以实现较低的时延，non-slot的调度对时延的要求较高，所以当终端被基站配置为采用non-slot的调度方式进行传输时，基站隐式指示终端在未知资源中要检测PDCCH。a) The terminal determines whether to detect the PDCCH according to whether it is a non-slot scheduling. Here, since the PDCCH (UL grant or DL grant) is detected in the unknown resource, a lower delay can be achieved, and the non-slot scheduling has higher requirements on the delay, so when the terminal is configured by the base station to use the non-slot When transmitting in the scheduling mode, the base station implicitly instructs the terminal to detect the PDCCH in the unknown resource.
b)终端根据是否被配置为C-DRX传输以确定是否在未知资源中检测PDCCH。这里，在配置了C-DRX的传输过程中，on Duration Timer表示在一个DRX周期里，UE睡醒后的在线时长，以PDCCH子帧个数为基本单位。为了减少终端醒来的时间，达到省电目的，当被配置为C-DRX传输时，基站隐式指示终端在未知资源中需要检测PDCCH，或隐式指示终端在未知资源中不需要检测PDCCH。b) The terminal determines whether to detect PDCCH in unknown resources according to whether it is configured for C-DRX transmission. Here, in the transmission process in which C-DRX is configured, on Duration Timer represents the online duration after the UE wakes up in a DRX cycle, and takes the number of PDCCH subframes as the basic unit. In order to reduce the time for the terminal to wake up and save power, when configured for C-DRX transmission, the base station implicitly indicates that the terminal needs to detect PDCCH in unknown resources, or implicitly indicates that the terminal does not need to detect PDCCH in unknown resources.
本发明实施例中，所述基站的指示可以是提前通知的，至少提前一个slot通知，这样可以提高未知资源中上行资源的利用率，减少PDCCH的盲检次数。In the embodiment of the present invention, the indication of the base station may be notified in advance, at least one slot is notified in advance, which can improve the utilization rate of uplink resources in unknown resources and reduce the number of blind detections of PDCCH.
本发明实施例中，若终端在未知资源中检测PDCCH，那么需要考虑如下方式中的一种或多种方式以保证上下行切换：In this embodiment of the present invention, if the terminal detects the PDCCH in an unknown resource, one or more of the following methods need to be considered to ensure uplink and downlink switching:
a)终端判断如果检测PDCCH的行为与切换为上行传输的行为冲突，则终端不再进行(放弃)PDCCH检测。a) The terminal determines that if the behavior of detecting the PDCCH conflicts with the behavior of switching to uplink transmission, the terminal will no longer perform (abandon) PDCCH detection.
b)终端不期望切换为上行传输的行为与PDCCH检测的行为冲突，也即终端判断如果检测PDCCH的行为与切换为上行传输的行为冲突，则终端认为是错误情况，终端具体行为取决于终端内置的预设条件，如果内置条件为在未知资源上检测PDCCH，则终端此时对PDCCH进行检测；否则，如果内置条件为在未知资源不检测PDCCH，则终端此时不对PDCCH进行检测。b) The terminal does not expect the behavior of switching to uplink transmission to conflict with the behavior of PDCCH detection, that is, the terminal judges that if the behavior of detecting PDCCH conflicts with the behavior of switching to uplink transmission, the terminal considers it to be an error situation, and the specific behavior of the terminal depends on the built-in behavior of the terminal. If the built-in condition is to detect the PDCCH on the unknown resource, the terminal will detect the PDCCH at this time; otherwise, if the built-in condition is not to detect the PDCCH on the unknown resource, the terminal will not detect the PDCCH at this time.
如图7所示，对上述a)和b)两种方式的统一描述，举例描述了什么情况下PDCCH的检测可能和切换为上行传输的行为冲突。在以下三种情况中：两个未知资源相邻；未知资源和上行资源相邻；下行资源和未知资源相邻。若终端判断检测PDCCH的行为与切换为上行传输的行为冲突，终端行为可以是：(1)不再进行PDCCH的检测(2)终端认为是错误情况，终端具体行为取决于终端实现。As shown in FIG. 7 , the unified description of the above two modes a) and b), for example, describes under what circumstances the detection of the PDCCH may conflict with the behavior of switching to uplink transmission. In the following three situations: two unknown resources are adjacent; unknown resources and uplink resources are adjacent; downlink resources and unknown resources are adjacent. If the terminal determines that the behavior of detecting PDCCH conflicts with the behavior of switching to uplink transmission, the behavior of the terminal may be: (1) no longer detect PDCCH (2) the terminal considers it to be an error situation, and the specific behavior of the terminal depends on the terminal implementation.
本发明实施例基站对终端在未知资源中是否检测PDCCH的行为进行指示，终端基于相应指示确定是否进行PDCCH检测，可解决终端是否在未知资源中检测PDCCH的问题，从而可以更灵活的适配时延、功耗的要求。In this embodiment of the present invention, the base station indicates whether the terminal detects the PDCCH in the unknown resource, and the terminal determines whether to perform the PDCCH detection based on the corresponding indication, which can solve the problem of whether the terminal detects the PDCCH in the unknown resource, so that the time of adaptation can be more flexible. delay and power consumption requirements.
以上所述，仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
