Description

[0001] Division Application Description

[0002] This application is a divisional application of a Chinese patent invention application with the application number 2017800007515, the filing date of July 31, 2017, and the invention creation name of "Method and Device for Indicating Transmission Direction". Technical Field

[0003] The present disclosure relates to the field of communications, and in particular, to a method and device for determining a transmission direction. Background Art

[0004] In the LTE (Long Term Evolution) system, according to different duplexing methods, it can be divided into two operating modes: FDD (Frequency Division Duplexing) and TDD (Time Division Duplexing). For the FDD mode, the uplink and downlink transmissions are implemented on different carriers. For the TDD mode, the uplink and downlink transmissions are implemented on the same carrier. Moreover, in the LTE system design, the uplink and downlink transmission directions of the terminal are predefined and it is impossible to completely dynamically change the uplink and downlink transmission directions of the terminal.

[0005] In the new generation of communication systems, the uplink and downlink transmission directions of the terminal may be dynamically changed. Therefore, if the terminal does not timely learn its transmission direction, it will bring greater detection complexity to itself and at the same time cause greater power consumption.

[0196] In one embodiment, a bandwidth part can be understood as a set of partial PRBs (Physical Resource Blocks) in a carrier.

For example: the base station configures 2 bandwidth parts for the terminal, such as Figure 1C .

[0197] In one embodiment, the transmission direction indication information on each bandwidth part is sent by the base station to the terminal. Optionally, the base station sends the transmission direction indication information through GC-PDCCH (Group Common Physical Downlink Control Channel, a physical downlink control channel for users in a group).

[0198] In one embodiment, there are many methods for determining the detection method, and it can be detected according to the detection method preset by the terminal and the base station, or it can be detected according to the method customized by the base station.

[0199] In step 120, detect the transmission direction indication information on the corresponding bandwidth part according to the determined detection method.

[0200] In step 130, determine the transmission direction of the corresponding bandwidth part according to the detected transmission direction indication information.

[0201] In an exemplary scenario, such as Figure 1BAs shown, the base station configures one or more bandwidth parts for the terminal, and the numerology on different bandwidth parts may be different. At this time, the base station sets signaling notification for instructing the terminal to detect the transmission direction of each bandwidth part, and sends the signaling notification to the terminal through the target signaling, so that the terminal can determine the detection method for detecting the transmission direction of each bandwidth part according to the signaling notification, and detect the transmission direction indication information on the corresponding bandwidth according to the detection method, and determine the transmission direction of the corresponding bandwidth part according to the detected transmission direction indication information.

[0202] Through the above steps 110 - step 130 in this embodiment, the terminal can first determine the detection method for detecting the transmission direction of each bandwidth part, and then detect the transmission direction indication information on the corresponding bandwidth according to the detection method, and then determine the transmission direction of the corresponding bandwidth part according to the detected transmission direction indication information. Through the above process, the terminal can accurately know the transmission direction of each bandwidth part, reducing the detection overhead of the terminal.

[0203] In one embodiment, for the above step 110, the terminal can completely determine the corresponding detection method according to the signaling notification of the base station.

[0204] In this way, the terminal can first receive the first signaling notification sent by the base station through the target signaling for instructing the terminal to detect the transmission direction of each bandwidth part, and then determine the detection method for detecting the transmission direction of each bandwidth part according to the first signaling notification. In this way, the terminal can accurately know the transmission direction of each bandwidth part under the indication of the base station, and also reduce the detection overhead of the terminal.

[0205] In one embodiment, the first signaling notification may include first information, second information, and third information; wherein, the first information includes one or more specified bandwidth parts, and the specified bandwidth parts are specified from all the configured bandwidth parts; the second information includes the pairing relationship corresponding to each specified bandwidth part, and the pairing relationship is used to characterize the relationship between the specified bandwidth part and one or more indicated bandwidth parts. The indicated bandwidth parts are the specified bandwidth parts or other bandwidth parts that are not specified for detection, and the transmission direction of the indicated bandwidth part is in the transmission direction indication information on the specified bandwidth part; the third information includes the configuration information of the transmission of the transmission direction indication information on each specified bandwidth part.

[0206] For example, the base station configures 4 bandwidth parts for the terminal, namely bandwidth part 1, bandwidth part 2, bandwidth part 3, and bandwidth part 4. The base station configures both bandwidth part 1 and bandwidth part 4 as specified bandwidth parts, and in the pairing relationship configured for the specified bandwidth part 1, the indicated bandwidth parts include bandwidth part 1, bandwidth part 2, and bandwidth part 3, and in the pairing relationship configured for the specified bandwidth part 4, the indicated bandwidth parts include bandwidth part 4.

[0207] Correspondingly, when the terminal executes step 110, the following method can be adopted:

[0208] Determine one or more specified bandwidth parts to be detected according to the first information; determine the pairing relationship corresponding to each specified bandwidth part according to the second information; determine the detection position corresponding to each specified bandwidth part according to the third information.

[0209] Correspondingly, when the terminal executes step 120, the following method can be adopted:

[0210] Detect the transmission direction indication information on each specified bandwidth part, and the transmission direction indication information on the specified bandwidth part carries the transmission directions of one or more indicated bandwidth parts.

[0211] When the terminal executes step 130, the following method can be adopted:

[0212] Determine the transmission directions of one or more indicated bandwidth parts carried by the transmission direction on each specified bandwidth part as the transmission directions of each of the indicated bandwidth parts according to the pairing relationship determined according to the second information.

[0213] In one embodiment, for the above step 110, the terminal can determine the corresponding detection method according to a pre-agreed protocol, or a combination of a pre-agreed protocol and base station signaling notification, which may include but is not limited to the following methods:

[0214] The first method is to detect all bandwidth parts.

[0215] 1-1. The terminal determines the bandwidth parts to be detected as all the configured bandwidth parts;

[0216] 1-2. The terminal determines the transmission direction carried in the transmission direction indication information on each configured bandwidth part as the transmission direction of the bandwidth part itself;

[0217] 1-3. The terminal determines the detection position corresponding to each configured bandwidth part.

[0218] Optionally, the above 1-1, 1-2, and 1-3 can be determined according to a pre-agreed protocol.

[0219] Optionally, the above 1-3 can also be notified by base station signaling, specifically as follows:

[0220] The terminal receives a second signaling notification sent by the base station through the target signaling, and the second signaling notification includes configuration information for transmitting direction indication information on each configured bandwidth part;

[0221] The terminal determines the detection position corresponding to each configured bandwidth part according to the second signaling notification.

[0222] Among them, the detection positions corresponding to each configured bandwidth part may be the same or different. If they are the same, they can be detected simultaneously; if they are different, they need to be detected separately.

[0223] Corresponding to the above first method, when the terminal executes step 120, it can adopt the following method:

[0224] Detect the transmission direction indication information on each configured bandwidth part, and the transmission direction indication information carries the transmission direction of the bandwidth part itself.

[0225] Corresponding to the above first method, when the terminal executes step 130, it can adopt the following method:

[0226] Determine the transmission direction carried in the transmission direction indication information on each configured bandwidth part as the transmission direction of the bandwidth part.

[0227] For example: The base station configures 4 bandwidth parts for the terminal, namely bandwidth part 1, bandwidth part 2, bandwidth part 3, and bandwidth part 4. The terminal detects bandwidth part 1 to obtain the transmission direction of bandwidth part 1; the terminal detects bandwidth part 2 to obtain the transmission direction of bandwidth part 2; the terminal detects bandwidth part 3 to obtain the transmission direction of bandwidth part 3; the terminal detects bandwidth part 4 to obtain the transmission direction of bandwidth part 4.

[0228] In this embodiment, through the above first method, the terminal can obtain the transmission directions of each bandwidth part itself by detecting all bandwidth parts. Through the above process, the terminal can accurately obtain the transmission direction of each bandwidth part and also improve the indication efficiency of the transmission direction.

[0229] The second method: Detect the specified bandwidth part.

[0230] 2-1. The terminal determines that the bandwidth part to be detected is one or more specified bandwidth parts, and the specified bandwidth parts are specified from all configured bandwidth parts;

[0231] 2-2. The terminal determines the pairing relationship corresponding to each specified bandwidth part. The pairing relationship is used to characterize the relationship between the specified bandwidth part and one or more indicated bandwidth parts. The indicated bandwidth part is the specified bandwidth part or other bandwidth parts that are not specified for detection. The transmission direction of the indicated bandwidth part is in the transmission direction indication information on the specified bandwidth part;

[0232] 2-3. The terminal determines the detection position corresponding to each specified bandwidth part.

[0233] Optionally, the above 2-1, 2-2, and 2-3 can be determined according to a pre-agreed protocol.

[0234] Optionally, the above 2-1 and 2-2 can also be notified by the base station signaling. Specifically:

[0235] Receive the third signaling notification sent by the base station through the target signaling. The third signaling notification includes the one or more specified bandwidth parts and the pairing relationship corresponding to each specified bandwidth part.

[0236] Optionally, the above 2-3 can also be notified by the base station signaling. Specifically:

[0237] Receive the fourth signaling notification sent by the base station through the target signaling. The fourth signaling notification includes the configuration information for the transmission of the transmission direction indication information on each specified bandwidth part;

[0238] Determine the detection position corresponding to each specified bandwidth part according to the fourth signaling notification.

[0239] Corresponding to the above second method, when the terminal executes step 120, it can adopt the following method:

[0240] Detect the transmission direction indication information on each specified bandwidth part. The transmission direction indication information on the specified bandwidth part carries the transmission directions of one or more indicated bandwidth parts.

[0241] Corresponding to the above second method, when the terminal executes step 130, it can adopt the following method:

[0242] Determine the transmission directions of the one or more indicated bandwidth parts carried by the transmission direction on each specified bandwidth part as the transmission directions of the respective indicated bandwidth parts according to the pairing relationship.

[0243] For example: The base station configures 4 bandwidth parts for the terminal, namely bandwidth part 1, bandwidth part 2, bandwidth part 3, and bandwidth part 4. The base station configures bandwidth part 1 as the specified bandwidth part, and in the pairing relationship corresponding to the specified bandwidth part 1, the indicated bandwidth parts include bandwidth part 1, bandwidth part 2, bandwidth part 3, and bandwidth part 4. In this way, the terminal only needs to detect 1 bandwidth part to obtain the transmission directions of 4 bandwidth parts, improving the indication efficiency of the transmission direction.

[0244] For another example: The base station configures 4 bandwidth parts for the terminal, namely bandwidth part 1, bandwidth part 2, bandwidth part 3, and bandwidth part 4. The base station configures bandwidth part 1 and bandwidth part 3 as the specified bandwidth parts. In the pairing relationship corresponding to the specified bandwidth part 1, the indicated bandwidth parts include bandwidth part 1 and bandwidth part 2. In the pairing relationship corresponding to the specified bandwidth part 3, the indicated bandwidth parts include bandwidth part 3 and bandwidth part 4. In this way, the terminal only needs to detect 2 bandwidth parts to obtain the transmission directions of 4 bandwidth parts, also improving the indication efficiency of the transmission direction.

[0245] For another example: The base station configures 4 bandwidth parts for the terminal, namely bandwidth part 1, bandwidth part 2, bandwidth part 3, and bandwidth part 4. The base station configures bandwidth part 1, bandwidth part 2, bandwidth part 3, and bandwidth part 4 as the specified bandwidth parts. In the pairing relationship corresponding to the specified bandwidth part 1, the indicated bandwidth part includes bandwidth part 2. In the pairing relationship corresponding to the specified bandwidth part 2, the indicated bandwidth part includes bandwidth part 3. In the pairing relationship corresponding to the specified bandwidth part 3, the indicated bandwidth part includes bandwidth part 4. In the pairing relationship corresponding to the specified bandwidth part 4, the indicated bandwidth part includes bandwidth part 1. In this way, the terminal can only obtain the transmission directions of these 4 bandwidth parts through the pairing relationship, thereby improving the reliability of the indication of the transmission direction.

[0246] In this embodiment, through the above second method, the terminal can determine the transmission directions of all the indicated bandwidth parts by detecting one or more specified bandwidth parts, and further know the transmission directions of all the bandwidth parts. Through the above process, the terminal can accurately know the transmission direction of each bandwidth part and also reduce the detection overhead of the terminal.

[0247] The third method: Detect the specified bandwidth part.

[0248] 3-1. The terminal determines that the bandwidth part to be detected is one or more specified bandwidth parts, and the specified bandwidth parts are specified from all the configured bandwidth parts;

[0249] 3-2. The terminal determines that the transmission direction carried in the transmission direction indication information on each specified bandwidth part is the transmission direction of the specified bandwidth part itself;

[0250] 3-3. The terminal determines the detection positions corresponding to each specified bandwidth part.

[0251] Optionally, the above 3-1, 3-2, and 3-3 can be determined according to a pre-agreed protocol.

[0252] Optionally, the above 3-1 can also be notified by the base station signaling, specifically:

[0253] Receive the fifth signaling notification sent by the base station through the target signaling, and the fifth signaling notification includes the one or more specified bandwidth parts.

[0254] Optionally, the above 3-3 can also be notified by the base station signaling, specifically:

[0255] Receive the sixth signaling notification sent by the base station through the target signaling, and the sixth signaling notification includes the configuration information of the transmission direction indication information transmitted on each specified bandwidth part;

[0256] Determine the detection positions corresponding to each specified bandwidth part according to the sixth signaling notification.

[0257] Corresponding to the above third method, when the terminal executes step 120, the following method can be adopted:

[0258] Detect the transmission direction indication information on each specified bandwidth part, and the transmission direction indication information carries the transmission direction of the specified bandwidth part itself.

[0259] Corresponding to the above third method, when the terminal executes step 130, the following method can be adopted:

[0260] Determine the transmission direction carried in the transmission direction indication information on each specified bandwidth part as the transmission direction of the specified bandwidth part;

[0261] Obtain the transmission directions of other bandwidth parts that are not specified for detection from the transmission directions of the specified bandwidth parts according to a predefined rule, and the predefined rule includes a rule for determining the transmission directions of other bandwidth parts that are not specified for detection according to the transmission directions of the specified bandwidth parts.

[0262] Optionally, the above predefined rule can also be notified by the base station signaling, specifically:

[0263] Receive the sixth signaling notification sent by the base station through the target signaling, and the sixth signaling notification includes the predefined rule, and the predefined rule includes a rule for determining the transmission directions of other bandwidth parts that are not specified for detection according to the transmission directions of the specified bandwidth parts.

[0264] For example, the base station configures 4 bandwidth parts for the terminal, namely bandwidth part 1, bandwidth part 2, bandwidth part 3, and bandwidth part 4. The predefined rule is that bandwidth part 1, bandwidth part 2, bandwidth part 3, and bandwidth part 4 are all the same. In this way, the terminal can detect the direction of only one of the bandwidth parts, and based on the predefined rule, the transmission directions of the other bandwidth parts can be deduced.

[0265] Another example: The base station configures 4 bandwidth parts for the terminal, namely bandwidth part 1, bandwidth part 2, bandwidth part 3, and bandwidth part 4. The predefined rule is that bandwidth part 1 and bandwidth part 2 are opposite. In this way, after the terminal detects the transmission direction of bandwidth part 1, it can also deduce the transmission direction of bandwidth part 2 according to the predefined rule.

[0266] In this embodiment, through the above third method, the terminal can detect one or more specified bandwidth parts, and based on the predefined rule, deduce the transmission directions of the other bandwidth parts that are not specified for detection from the transmission directions of these specified bandwidth parts, so as to know the transmission directions of all the configured bandwidth parts. Through the above process, the terminal can accurately know the transmission direction of each bandwidth part, and also reduce the detection overhead of the terminal.

[0267] In addition, due to the different contents included in the signaling notification of the base station, the corresponding indication processes of the transmission directions are also different:

[0268] (1) The signaling notification includes the configuration information of the transmission direction indication information transmitted on each bandwidth part. For the indication process of the transmission direction, reference can be made to the Figure 2A illustrated embodiment, which will not be elaborated here.

[0269] (2) The signaling notification includes one or more specified bandwidth parts. For the indication process of the transmission direction, reference can be made to the Figure 3 illustrated embodiment, which will not be elaborated here.

[0270] (3) The signaling notification includes one or more specified bandwidth parts, and also includes a predefined rule. The predefined rule includes a rule for determining the transmission directions of the other bandwidth parts that are not specified for detection based on the transmission directions of the specified bandwidth parts. For the indication process of the transmission direction, reference can be made to the Figure 4 illustrated embodiment, which will not be elaborated here.

[0271] Optionally, the base station sends the signaling notification to the terminal through a target signaling. The target signaling includes at least one of the following: radio resource control signaling, media access control address control unit, and physical layer signaling.

[0272] In an embodiment of the present disclosure, the base station may send the notification information to the terminal by sending RRC (Radio Resource Control) signaling, MAC CE (MAC Control Element), or physical layer signaling to the terminal, and the terminal can directly receive it. Among them, the physical layer signaling generally refers to the signaling carried by PDCCH.

[0273] The following uses specific embodiments to illustrate the technical solutions provided by the embodiments of the present disclosure.

[0274] Figure 2A is a flowchart of another method for determining the transmission direction shown according to an exemplary embodiment; this method for determining the transmission direction can be applied to a terminal, and the base station configures at least one bandwidth part for the terminal, such as Figure 2A shown, and this method for determining the transmission direction includes the following steps 210-240:

[0275] In step 210, receive a signaling notification sent by the base station through a target signaling for instructing the terminal to detect the transmission direction of each bandwidth part, and the signaling notification includes configuration information for the transmission of transmission direction indication information on each bandwidth part. Among them, the target signaling may include at least one of the following: radio resource control signaling, system information, media access control address control unit, and physical layer signaling.

[0276] In step 220, determine the detection position corresponding to each bandwidth part according to the configuration information for the transmission of transmission direction indication information on each bandwidth part. The configuration information may include information such as a configuration period, a transmission position in the time domain and the frequency domain, beam information, and information on the numerology of the transmission, and the information included in the configuration information is applicable to all embodiments of the present disclosure.

[0277] In an embodiment of the present disclosure, the detection positions corresponding to each bandwidth part determined according to the configuration information for the transmission of transmission direction indication information on each bandwidth part may be the same. For example, detect the transmission direction indication information on 2 bandwidth parts at the same position, as shown in 2B; they may also be different. For example, detect the transmission direction indication information on 2 bandwidth parts at different positions, as shown in 2C. Figure 1C in; Figure 1C in the 2 bandwidth parts shown;

[0278] In step 230, at the detection position corresponding to each determined bandwidth part, detect the transmission direction indication information on the corresponding bandwidth.

[0279] In step 240, determine the transmission direction of the corresponding bandwidth part according to the detected transmission direction indication information.

[0280] In this embodiment, through the above steps 210 - 240, the terminal can determine the detection position corresponding to each bandwidth part according to the configuration information indicated in the signaling notification, detect the transmission direction indication information on the corresponding bandwidth at the determined detection position, and determine the transmission direction of the corresponding bandwidth part according to the detected transmission direction indication information. Through the above process, the terminal can dynamically learn the transmission direction on each bandwidth part, improving the indication accuracy of the transmission direction.

[0281] Figure 3 is a flowchart of another method for determining the transmission direction shown according to an exemplary embodiment; this method for determining the transmission direction can be applied to a terminal, and the base station configures at least one bandwidth part for the terminal, such as Figure 3 shown, this method for determining the transmission direction includes the following steps 310 - 340:

[0282] In step 310, receive a signaling notification sent by the base station through a target signaling for instructing the terminal to detect the transmission direction of each bandwidth part, where the signaling notification includes one or more specified bandwidth parts. Among them, the target signaling may include at least one of the following: radio resource control signaling, system information, media access control address control unit, and physical layer signaling.

[0283] In step 320, determine that the bandwidth parts to be detected are one or more specified bandwidth parts according to the signaling notification.

[0284] In step 330, detect the transmission direction indication information on each specified bandwidth part, where the transmission direction indication information carries the transmission direction of the specified bandwidth part itself.

[0285] In step 340, determine the transmission direction of each specified bandwidth part according to the transmission direction indication information on each specified bandwidth part; and obtain the transmission directions of other bandwidth parts that are not specified for detection from the transmission directions of each specified bandwidth part according to a predefined rule.

[0286] In the embodiments of the present disclosure, the predefined rule may be a rule negotiated between the base station and the terminal for learning the transmission directions of other bandwidth parts from the transmission directions of a part of the bandwidth parts. For example: The base station configures 4 bandwidth parts for the terminal, namely bandwidth part 1, bandwidth part 2, bandwidth part 3, and bandwidth part 4. The predefined rule is that the transmission directions on bandwidth part 1 and bandwidth part 3 are the same, and the transmission directions on bandwidth part 2 and bandwidth part 4 are the same. If the base station designates the detection of bandwidth part 1 and bandwidth part 2, after the terminal detects the transmission directions of bandwidth part 1 and bandwidth part 2, it can obtain the transmission directions of bandwidth part 3 and bandwidth part 4 according to the predefined rule, which can improve the indication efficiency of the transmission direction and reduce the detection overhead of the terminal.

[0287] In this embodiment, through the above steps 310 - 340, the terminal can determine the bandwidth part to be detected according to the signaling notification. The bandwidth part to be detected includes one or more specified bandwidth parts indicated by the base station for detection, and detect the transmission direction indication information on the corresponding bandwidth. After determining the transmission direction on each bandwidth part, then according to the predefined rule, obtain the transmission direction of other bandwidth parts not specified for detection from the transmission direction of each specified bandwidth part. Through the above process, the terminal can not only reduce the detection overhead, but also accurately know the transmission direction of each bandwidth part, improving the indication efficiency of the transmission direction.

[0288] Figure 4 FIG. is a flowchart of another method for determining the transmission direction shown according to an exemplary embodiment; this method for determining the transmission direction can be applied to a terminal, and the base station configures at least one bandwidth part for the terminal, such as Figure 4 shown, this method for determining the transmission direction includes the following steps 410 - 440:

[0289] In step 410, receive a signaling notification sent by the base station through the target signaling for instructing the terminal to detect the transmission direction of each bandwidth part. The signaling notification includes one or more specified bandwidth parts, and a predefined rule, where the predefined rule includes a rule for determining the transmission direction of other bandwidth parts not specified for detection according to the transmission direction of the specified bandwidth part. Among them, the target signaling may include at least one of the following: radio resource control signaling, system information, media access control address control unit, and physical layer signaling.

[0290] In the embodiments of the present disclosure, the predefined rule may be defined by the base station and sent to the terminal, including a rule for determining the transmission direction of other bandwidth parts not specified for detection according to the transmission direction of the specified bandwidth part. For example: The base station configures 4 bandwidth parts for the terminal, namely bandwidth part 1, bandwidth part 2, bandwidth part 3, and bandwidth part 4, and specifies the terminal to detect the transmission direction indication information on bandwidth part 1 and bandwidth part 2. In order to facilitate the terminal to know the transmission direction of all bandwidth parts, the base station also defines that the transmission direction on bandwidth part 1 and bandwidth part 3 is the same, and the transmission direction on bandwidth part 2 and bandwidth part 4 is the same. In this way, after the terminal detects the transmission direction indication information on bandwidth part 1 and bandwidth part 2 and obtains the transmission direction of bandwidth part 1 and bandwidth part 2, it can know the transmission direction of bandwidth part 3 and bandwidth part 4 according to the predefined rule. Finally, the terminal knows the transmission direction of all 4 bandwidth parts, namely bandwidth part 1, bandwidth part 2, bandwidth part 3, and bandwidth part 4.

[0291] In step 420, it is determined, according to the signaling notification, that the bandwidth part to be detected is one or more specified bandwidth parts.

[0292] In step 430, the transmission direction indication information on each specified bandwidth part is detected, and the transmission direction indication information carries the transmission direction of the specified bandwidth part itself.

[0293] In step 440, the transmission direction of each specified bandwidth part is determined according to the transmission direction indication information on each specified bandwidth part; and the transmission directions of other bandwidth parts that are not specified for detection are obtained from the transmission directions of each specified bandwidth part according to the predefined rules indicated by the base station.

[0294] In this embodiment, through the above steps 410 to 440, the signaling notification includes both the specified bandwidth parts and the predefined rules. In this way, after the terminal detects the transmission direction indication information of the specified bandwidth parts and determines the transmission direction of each specified bandwidth part, it can obtain the transmission directions of other bandwidth parts that are not specified for detection according to the predefined rules provided by the base station, and finally obtain the transmission directions of all bandwidth parts. Through the above process, the terminal can dynamically obtain the transmission direction of each bandwidth part through the signaling notification sent by the base station, and can also reduce the detection overhead of the terminal, thereby improving the indication efficiency of the transmission direction.

[0295] Figure 5 is a flowchart of a method for determining a transmission direction shown according to an exemplary embodiment. The method for determining the transmission direction can be applied to a base station, and the base station configures at least one bandwidth part for a terminal, such as Figure 5 shown, and the method for determining the transmission direction includes the following steps 510 to 520:

[0296] In step 510, a signaling notification for instructing the terminal to detect the transmission direction of each bandwidth part is set.

[0297] In one embodiment, the signaling notification includes first information, and / or second information, and / or third information; the first information includes one or more specified bandwidth parts, and the specified bandwidth parts are specified from all the configured bandwidth parts; the second information includes the pairing relationship corresponding to each specified bandwidth part, and the pairing relationship is used to characterize the relationship between the specified bandwidth part and one or more indicated bandwidth parts, and the indicated bandwidth part is the specified bandwidth part or other bandwidth parts that are not specified for detection, and the transmission direction of the indicated bandwidth part is in the transmission direction indication information on the specified bandwidth part; the third information includes the configuration information for transmitting the transmission direction indication information on each specified bandwidth part.

[0298] In one embodiment, the signaling notification includes configuration information for transmitting indication information on the transmission direction on each configured bandwidth part.

[0299] In one embodiment, the signaling notification includes a predefined rule, and the predefined rule includes a rule for determining the transmission direction of other bandwidth parts not specified for detection according to the transmission direction of the specified bandwidth part.

[0300] In step 520, the signaling notification is sent to the terminal through target signaling, so that the detection method for detecting the transmission direction of each bandwidth part is determined according to the signaling notification.

[0301] In this embodiment, through the above steps 510 - 520, the base station can set the signaling notification for instructing the terminal to detect the transmission direction of each bandwidth part, and send the signaling notification to the terminal through target signaling. In this way, the terminal can determine the detection method for detecting the transmission direction of each bandwidth part according to the signaling notification, and then perform detection according to this detection method, and finally learn the transmission direction of each bandwidth part, thereby improving the indication reliability of the transmission direction, also improving the indication efficiency of the transmission direction, and reducing the detection overhead of the terminal.
