Patent Description:
In a Long Term Evolution (LTE) system, there are two operating modes: Frequency Division Duplexing (FDD) and Time Division Duplexing (TDD). For the FDD mode, uplink and downlink transmissions are implemented on different carriers. For the TDD mode, uplink and downlink transmissions are implemented on the same carrier. Moreover, in the design of an LTE system, uplink and downlink transmission directions of a terminal are predefined, and it is impossible to completely and dynamically change the uplink and downlink transmission directions of the terminal.

In a new generation communication system, the uplink and downlink transmission directions of a terminal may be dynamically changed. Therefore, if the terminal does not know its transmission direction in time, it will bring greater detection complexity to itself and also cause greater power consumption.

Related technology is known from <NPL> and from <NPL>.

To overcome the problems in the related art, the embodiments of the present disclosure provide a method and device for indicating a transmission direction.

According to a first aspect of the embodiments of the present disclosure, a method for indicating a transmission direction is provided and is implemented by a terminal, as described in any one of claims <NUM>-<NUM>.

According to a third aspect of the embodiments of the present disclosure, a device for indicating a transmission direction is provided and is implemented by a terminal, as described in any one of claims <NUM>-<NUM>.

The technical solutions provided by the embodiments of the present disclosure includes the following beneficial effects.

A terminal first determines a detection mode configured for detecting a transmission direction of each bandwidth part, detects transmission direction indication information about a corresponding bandwidth according to the detection mode, and then determines a transmission direction of the corresponding bandwidth part according to the detected transmission direction indication information. The terminal can accurately know a transmission direction of each bandwidth part by carrying out the above process, thereby reducing the detection cost of the terminal.

The terminal can detect one or more designated bandwidth parts and can derive any other bandwidth part that is not designated to be detected from the transmission directions of the designated bandwidth parts according to a predefined rule, thereby knowing transmission directions of all configured bandwidth parts. With the above process, the terminal can accurately know a transmission direction of each bandwidth part, thereby reducing the detection cost of the terminal.

<FIG> is a flowchart of a method for indicating a transmission direction according to an exemplary embodiment. <FIG> is a scene diagram of a method for indicating a transmission direction according to an exemplary embodiment. The method for indicating a transmission direction may be applied to a terminal. A base station may configure at least one bandwidth part for the terminal. As shown in <FIG>, the method for indicating a transmission direction includes the following steps <NUM>-<NUM>.

In step <NUM>, a detection mode configured for detecting a transmission direction of configured each bandwidth part is determined.

In an embodiment, the bandwidth part may be understood as a set of part of Physical Resource Blocks (PRB) in one carrier. Since the bandwidth of one carrier may be wider in a new generation communication system, the terminal may be not able to support the entire bandwidth and can support transmission on a bandwidth part only. For example, the base station configures two bandwidth parts for the terminal, as shown in <FIG>.

In an embodiment, the transmission direction indication information about each bandwidth part may be sent by the base station to the terminal. Optionally, the base station may send transmission direction indication information by using a Group Common Physical Downlink Control Channel (GC-PDCCH).

In an embodiment, there may be many methods for determining a detection mode. The detection may be carried out according to a detection mode which is set by the terminal and the base station in advance, or may be carried out according to a mode customized by the base station.

In step <NUM>, transmission direction indication information about a corresponding bandwidth part is detected according to the determined detection mode.

In step <NUM>, the transmission direction of the corresponding bandwidth part is determined according to the detected transmission direction indication information.

In an exemplary scene, as shown in <FIG>, the base station may configure one or more bandwidth parts for the terminal, and the numerology on different bandwidth parts may be different. In this case, the base station may set a signaling notification for instructing the terminal to detect a transmission direction of each bandwidth part, and send the signaling notification to the terminal through target signaling, so that the terminal can determine, according to the signaling notification, a detection mode configured for detecting the transmission direction of each bandwidth part, detect transmission direction indication information about a corresponding bandwidth according to the detection mode, and determine the transmission direction of the corresponding bandwidth part according to the detected transmission direction indication information.

In the present embodiment, through step <NUM> to step <NUM>, a terminal may determine a detection mode configured for detecting a transmission direction of each bandwidth part, detect transmission direction indication information about a corresponding bandwidth according to the detection mode, and then determine the transmission direction of the corresponding bandwidth part according to the detected transmission direction indication information. With the above process, the terminal can accurately know a transmission direction of each bandwidth part, thereby reducing the detection cost of the terminal.

In an embodiment, for step <NUM>, the terminal may determine the corresponding detection mode completely according to the signaling notification from the base station.

In this way, the terminal may receive a first signaling notification sent by the base station through target signaling for instructing the terminal to detect a transmission direction of each bandwidth part, and determine a detection mode configured for detecting the transmission direction of each bandwidth part according to the first signaling notification, so that the terminal can accurately know the transmission direction of each bandwidth part under the instruction of the base station, thereby reducing the detection cost of the terminal.

In an embodiment, the first signaling notification may include first information, second information and third information. The first information may include information about one or more designated bandwidth parts, each of the one or more designated bandwidth parts being one designated from all configured bandwidth parts. The second information may include a pairing relationship corresponding to each of the one or more designated bandwidth parts, the pairing relationship being for representing a relationship between the designated bandwidth part and one or more indicated bandwidth parts, the indicated bandwidth part being the designated bandwidth part or any other bandwidth part that is not designated to be detected, information about the transmission direction of the indicated bandwidth part being carried in the transmission direction indication information about the designated bandwidth part. The third information may include configuration information transmitted by the transmission direction indication information about each of the one or more designated bandwidth parts.

For example, the base station configures four bandwidth parts for the terminal, namely, a bandwidth part <NUM>, a bandwidth part <NUM>, a bandwidth part <NUM>, and a bandwidth part <NUM>. The bandwidth part <NUM> and the bandwidth part <NUM> configured by the base station are both designated bandwidth parts, indicated bandwidth parts in a pairing relationship corresponding to the configured designated bandwidth part <NUM> include the bandwidth part <NUM>, the bandwidth part <NUM> and the bandwidth part <NUM>, and an indicated bandwidth part in a pairing relationship corresponding to the configured designated bandwidth part <NUM> includes the bandwidth part <NUM>.

Correspondingly, the terminal may implement step <NUM> in the following manners:
a bandwidth part to be detected is determined as one or more designated bandwidth parts according to the first information; a pairing relationship corresponding to each of the one or more designated bandwidth parts is determined according to the second information; and a detection position corresponding to each of one or more designated bandwidth parts is determined according to the third information.

Correspondingly, the terminal may implement step <NUM> in the following manners:
transmission direction indication information about each designated bandwidth part is detected, the transmission direction indication information about the designated bandwidth part carrying information about a transmission direction of one or more indicated bandwidth parts.

The terminal may implement step <NUM> in the following manners:
the transmission direction of one or more indicated bandwidth parts indicated in the transmission direction indication information about each designated bandwidth part is determined as the transmission direction of each of the indicated bandwidth parts according to the pairing relationship determined by the second information.

In an embodiment, for step <NUM>, the terminal may determine a corresponding detection mode according to a protocol agreed in advance or a combination of a protocol agreed in advance and a signaling notification from the base station, which may include, but is not limited to, the following modes.

In the first manner, all bandwidth parts are detected.

Optionally, <NUM>-<NUM>, <NUM>-<NUM> and <NUM>-<NUM> may be determined according to a protocol agreed in advance.

Optionally, <NUM>-<NUM> may also be carried out through a signaling notification from the base station, specifically:.

The detected positions corresponding to the configured bandwidth parts may be the same or different. If they are the same, they may be detected at the same time; if they are different, they need to be detected separately.

Corresponding to the first manner, the terminal may implement the step <NUM> in the following manners:
transmission direction indication information about configured each bandwidth part is detected, the transmission direction indication information carrying information about a transmission direction of the bandwidth part.

Corresponding to the first manner, the terminal may implement the step <NUM> in the following manners:
a transmission direction indicated in the transmission direction indication information about configured each bandwidth part is determined as a transmission direction of the bandwidth part.

For example, the base station configures four bandwidth parts for the terminal, namely, a bandwidth part <NUM>, a bandwidth part <NUM>, a bandwidth part <NUM>, and a bandwidth part <NUM>. The terminal may detect the bandwidth part <NUM> to obtain a transmission direction of the bandwidth part <NUM>. The terminal may detect the bandwidth part <NUM> to obtain a transmission direction of the bandwidth part <NUM>. The terminal may detect the bandwidth part <NUM> to obtain a transmission direction of the bandwidth part <NUM>. The terminal may detect the bandwidth part <NUM> to obtain a transmission direction of the bandwidth part <NUM>.

In the present embodiment, through the first manner, the terminal may know a transmission direction of each bandwidth part by detecting all bandwidth parts. With the above process, the terminal can accurately know a transmission direction of each bandwidth part, thereby improving the indication efficiency of the transmission direction.

In the second manner, a designated bandwidth part is detected.

Optionally, <NUM>-<NUM> and <NUM>-<NUM> may also be carried out by use of a signaling notification from the base station, specifically:
a third signaling notification sent by the base station through target signaling is received, the third signaling notification including the one or more designated bandwidth parts and including the pairing relationship corresponding to each designated bandwidth part.

Optionally, <NUM>-<NUM> may also be carried out by use of a signaling notification from the base station, specifically:.

Corresponding to the second manner, the terminal may implement the step <NUM> in the following manners:
transmission direction indication information about each designated bandwidth part is detected, the transmission direction indication information about the designated bandwidth part carrying information about a transmission direction of one or more indicated bandwidth parts.

Corresponding to the second manner, the terminal may implement the step <NUM> in the following manners:
the transmission direction of one or more indicated bandwidth parts indicated in the transmission direction indication information about each designated bandwidth part is determined as the transmission direction of each indicated bandwidth part according to the pairing relationship.

For example, the base station configures four bandwidth parts for the terminal, namely, a bandwidth part <NUM>, a bandwidth part <NUM>, a bandwidth part <NUM>, and a bandwidth part <NUM>. The bandwidth part <NUM> configured by the base station is a designated bandwidth part, and indicated bandwidth parts in a pairing relationship corresponding to the configured designated bandwidth part <NUM> include the bandwidth part <NUM>, the bandwidth part <NUM>, the bandwidth part <NUM>, and the bandwidth part <NUM>, so that the terminal can obtain transmission directions of four bandwidth parts by detecting only one bandwidth part, thereby improving the indication efficiency of the transmission direction.

For another example, the base station configures four bandwidth parts for the terminal, namely, a bandwidth part <NUM>, a bandwidth part <NUM>, a bandwidth part <NUM>, and a bandwidth part <NUM>. The bandwidth part <NUM> and the bandwidth part <NUM> configured by the base station are designated bandwidth parts, indicated bandwidth parts in a pairing relationship corresponding to the configured designated bandwidth part <NUM> include the bandwidth part <NUM> and the bandwidth part <NUM>, and indicated bandwidth parts in a pairing relationship corresponding to the configured designated bandwidth part <NUM> include the bandwidth part <NUM> and the bandwidth part <NUM>, so that the terminal can obtain transmission directions of four bandwidth parts by detecting only two bandwidth parts, thereby improving the indication efficiency of the transmission direction.

For another example, the base station configures four bandwidth parts for the terminal, namely, a bandwidth part <NUM>, a bandwidth part <NUM>, a bandwidth part <NUM>, and a bandwidth part <NUM>. The bandwidth part <NUM>, the bandwidth part <NUM>, the bandwidth part <NUM> and the bandwidth part <NUM> configured by the base station are designated bandwidth parts, an indicated bandwidth part in a pairing relationship corresponding to the configured designated bandwidth part <NUM> includes the bandwidth part <NUM>, an indicated bandwidth part in a pairing relationship corresponding to the configured designated bandwidth part <NUM> includes the bandwidth part <NUM>, an indicated bandwidth part in a pairing relationship corresponding to the configured designated bandwidth part <NUM> includes the bandwidth part <NUM>, and an indicated bandwidth part in a pairing relationship corresponding to the configured designated bandwidth part <NUM> includes the bandwidth part <NUM>, so that the terminal can obtain transmission directions of four bandwidth parts by the pairing relationship, thereby improving the indication reliability of the transmission direction.

In the present embodiment, through the second manner, the terminal can determine transmission directions of all indicated bandwidth parts by detecting one or more designated bandwidth parts, thereby knowing the transmission directions of all bandwidth parts. With the above process, the terminal can accurately know a transmission direction of each bandwidth part, thereby reducing the detection cost of the terminal.

In the third manner, a designated bandwidth part is detected.

Optionally, <NUM>-<NUM> may also be carried out by use of a signaling notification from the base station, specifically:

Optionally, the predefined rule may also be carried out by use of a signaling notification from the base station, specifically:
a sixth signaling notification sent by the base station through target signaling is received, the sixth signaling notification including a predefined rule, the predefined rule including a rule of determining a transmission direction of any other bandwidth part that is not designated to be detected according to the transmission direction of the designated bandwidth part.

For example, the base station configures four bandwidth parts for the terminal, namely, a bandwidth part <NUM>, a bandwidth part <NUM>, a bandwidth part <NUM>, and a bandwidth part <NUM>. The predefined rule is that the bandwidth part <NUM>, the bandwidth part <NUM>, the bandwidth part <NUM>, and the bandwidth part <NUM> are all the same, so that the terminal can detect the direction of one of the bandwidth parts only to derive a transmission directions of other bandwidth parts according to the predefined rule.

For another example, the base station configures four bandwidth parts for the terminal, namely, a bandwidth part <NUM>, a bandwidth part <NUM>, a bandwidth part <NUM>, and a bandwidth part <NUM>. The predefined rule is that the bandwidth part <NUM> and the bandwidth part <NUM> are opposite, so that after the transmission direction of the bandwidth part <NUM> is detected, the terminal can derive the transmission direction of the bandwidth part <NUM> according to the predefined rule.

In the present embodiment, through the third manner, the terminal can detect one or more designated bandwidth parts, and derive any other bandwidth part that is not designated to be detected from the transmission directions of the designated bandwidth parts according to a predefined rule, thereby knowing transmission directions of all configured bandwidth parts. With the above process, the terminal can accurately know a transmission direction of each bandwidth part, thereby reducing the detection cost of the terminal.

In addition, since the content included in the signaling notification from the base station is different, the corresponding process of indicating the transmission direction is also different:.

Optionally, the base station may send the signaling notification to the terminal through target signaling. The target signaling may include at least one of the following: RRC signaling, a MAC CE, and physical layer signaling.

In the embodiments of the present disclosure, the base station may send notification information to the terminal by sending RRC signaling, a MAC CE or physical layer signaling to the terminal, and the terminal may receive the signaling directly. The physical layer signaling generally refers to signaling carried by a PDCCH.

The technical solutions provided by the embodiments of the present disclosure are described below by using specific embodiments.

<FIG> is a flowchart of another method for indicating a transmission direction according to an exemplary embodiment. The method for indicating a transmission direction may be applied to a terminal. A base station configures at least one bandwidth part for the terminal. As shown in <FIG>, the method for indicating a transmission direction includes the following steps <NUM>-<NUM>.

In step <NUM>, a signaling notification sent by the base station through target signaling for instructing the terminal to detect a transmission direction of each bandwidth part is received, the signaling notification including configuration information transmitted by the transmission direction indication information about each bandwidth part. The target signaling may include at least one of the following: RRC signaling, system information, a MAC CE, and physical layer signaling.

In step <NUM>, a detection position corresponding to each bandwidth part is determined according to the configuration information transmitted by the transmission direction indication information about each bandwidth part. The configuration information may include information such as a configuration period, transmission positions in a time domain and a frequency domain, beam information, and information about the transmitted numerology; and the information included in the configuration information is applicable to all embodiments of the present disclosure.

In the embodiments of the present disclosure, the detection position corresponding to each bandwidth part determined according to the configuration information transmitted by the transmission direction indication information about each bandwidth part may be the same, for example, the transmission direction indication information about two bandwidth parts in <FIG> is detected at the same position, as shown in <FIG>. Or the determiend detection positions may be different, for example, the transmission direction indication information about two bandwidth parts in <FIG> is detected at different positions, as shown in <FIG>.

In step <NUM>, transmission direction indication information about a corresponding bandwidth is detected at the determined detection position corresponding to each bandwidth part.

In the present embodiment, through step <NUM> to step <NUM>, the terminal can determine a detection position corresponding to each bandwidth part according to configuration information indicated in a signaling notification, detect transmission direction indication information about a 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. With the above process, the terminal can dynamically know a transmission direction of each bandwidth part, thereby improving the indication accuracy of the transmission direction.

In step <NUM>, a signaling notification sent by the base station through target signaling for instructing the terminal to detect a transmission direction of each bandwidth part is received, the signaling notification including one or more designated bandwidth parts. The target signaling may include at least one of the following: RRC signaling, system information, a MAC CE, and physical layer signaling.

In step <NUM>, a bandwidth part to be detected is determined as one or more designated bandwidth parts according to the signaling notification.

In step <NUM>, transmission direction indication information about each designated bandwidth part is detected, the transmission direction indication information carrying information about a transmission direction of the designated bandwidth part.

In step <NUM>, according to the transmission direction indication information about each designated bandwidth part, a transmission direction of the designated bandwidth part is determined, and a transmission direction of any other bandwidth part that is not designated to be detected is obtained from the transmission direction of each designated bandwidth part according to a predefined rule.

In the embodiments of the present disclosure, the predefined rule may be a rule negotiated by the base station and the terminal for knowing the transmission direction of other bandwidth parts from the transmission direction of part of the bandwidth parts. For example: the base station configures four bandwidth parts for the terminal, namely a bandwidth part <NUM>, a bandwidth part <NUM>, a bandwidth part <NUM> and a bandwidth part <NUM>; the predefined rule is that the transmission directions of the bandwidth part <NUM> and the bandwidth part <NUM> are the same and the transmission directions of the bandwidth part <NUM> and the bandwidth part <NUM> are the same; in a case that the base station designates to detect the bandwidth part <NUM> and the bandwidth part <NUM>, the transmission directions of the bandwidth part <NUM> and the bandwidth part <NUM> can be known according to the predefined rule after the transmission directions of the bandwidth part <NUM> and the bandwidth part <NUM> are detected, so that the indication efficiency of the transmission direction can be improved, and the detection overheads of the terminal can be reduced.

In the present embodiment, through step <NUM> to step <NUM>, the terminal can determine a bandwidth part to be detected according to a signaling notification; the bandwidth part to be detected may include one or more designated bandwidth parts instructed to be detected by the base station. Transmission direction indication information about a corresponding bandwidth may be detected, and after the transmission direction of each bandwidth part is determined, the transmission direction of any other bandwidth part that is not designated to be detected can be known from the transmission direction of each designated bandwidth part according to a predefined rule. With the above process, the terminal can reduce detection overheads, and also can accurately know a transmission direction of each bandwidth part, thereby improving the indication efficiency of the transmission direction.

In step <NUM>, a signaling notification sent by the base station through target signaling for instructing the terminal to detect a transmission direction of each bandwidth part is received, the signaling notification including one or more designated bandwidth parts and a predefined rule, the predefined rule including a rule of determining a transmission direction of any other bandwidth part that is not designated to be detected according to the transmission direction of the designated bandwidth part. The target signaling may include at least one of the following: RRC signaling, system information, a MAC CE, and physical layer signaling.

In the embodiments of the present disclosure, the predefined rule may be defined by the base station and sent to the terminal by the base station, and may include a rule of determining a transmission direction of any other bandwidth part that is not designated to be detected according to the transmission direction of the designated bandwidth part.

In order to enable the terminal to know the transmission directions of all bandwidth parts, the base station also may define that the transmission directions of the bandwidth part <NUM> and the bandwidth part <NUM> are the same and the transmission directions of the bandwidth part <NUM> and the bandwidth part <NUM> are the same. Therefore, after the transmission direction indication information about the bandwidth part <NUM> and the bandwidth part <NUM> is detected and the transmission directions of the bandwidth part <NUM> and the bandwidth part <NUM> are obtained, the terminal may know the transmission directions of the bandwidth part <NUM> and the bandwidth part <NUM> according to the predefined rule, and finally, the terminal can know the transmission directions of all bandwidth parts, namely four bandwidth parts: the bandwidth part <NUM>, the bandwidth part <NUM>, the bandwidth part <NUM> and the bandwidth part <NUM>.

In step <NUM>, according to the transmission direction indication information about each designated bandwidth part, a transmission direction of the designated bandwidth part is determined, and a transmission direction of any other bandwidth part that is not designated to be detected is obtained from the transmission direction of each designated bandwidth part according to a predefined rule indicated by the base station.

In the present embodiment, through step <NUM> to step <NUM>, the signaling notification may include information about a designated bandwidth part and further include a predefined rule, so that after the transmission direction indication information about the designated bandwidth part is detected and the transmission direction of each designated bandwidth part is determined, the terminal can know the transmission direction of any other bandwidth part that is not designated to be detected according to a predefined rule provided by the base station, and finally know the transmission directions of all bandwidth parts. With the above process, the terminal can dynamically know the transmission direction of each bandwidth part by means of a signaling notification sent by the base station and the detection overheads of the terminal can be reduced, thereby improving the indication efficiency of the transmission direction.
