In view of the application of the new generation communication system on the unlicensed spectrum, since the communication system running on the unlicensed spectrum needs to first detect whether a channel is idle, a carrier or bandwidth part may contain multiple channel detection units, then channel detection results on different channel detection units may be inconsistent with each other. As a result, a part of the control information cannot be transmitted because the channel is not available. In a new generation communication system, the transmission of control signaling is carried on a control resource set (CORESET), and the configuration of the control resource set may be continuous or discontinuous in the frequency domain. In the related art, in order to ensure a reception performance of the control information, the user equipment has to detect the control signaling through a detection method with high complexity.

New Internet applications such as virtual reality (VR)/augmented reality (AR) and vehicle-to-vehicle communication continue to spring up, which has put forward higher requirements for wireless communication technology, and driven the continuous evolution of wireless communication technology to meet the needs of applications. At present, cellular mobile communication technology is in the evolution stage of a new generation technology. An important feature of the new generation technology is to support flexible configuration of various service types. Different service types have different requirements for wireless communication technologies. For example, requirements for Enhanced Mobile Broad Band (eMBB) service mainly focus on large bandwidth and high rate; requirements for Ultra Reliable & Low Latency Communication (URLLC) service mainly focus on high reliability and low latency; and requirements for massive Machine Type Communication (mMTC) service mainly focus on large number of connections. Therefore, a new generation of wireless communication system requires a flexible and configurable design to support the transmission of various service types.
As impelled by the service requirements, the service requirements cannot be met by only using the licensed spectrum, thus the mobile network is considered to be deployed on the unlicensed frequency band. However, other systems such as a Wi-Fi system might be existed in the unlicensed frequency band. Therefore, it needs to study how to ensure that different communication systems share resources fairly on the unlicensed frequency band.
In the development process of a wireless communication system, for the unlicensed spectrum, in the 3rd Generation Partnership Project (3GPP), a mechanism of license assisted access (LAA) is proposed to use the unlicensed spectrum. That is to say, the use of unlicensed frequency bands is achieved with the assist of the licensed frequency bands. In order to ensure the coexistence with other system such as the Wi-Fi on the unlicensed frequency band, a mechanism for channel detection before data transmission is also introduced in LAA. When data is to be transmitted, the transmitter needs to detect whether the channel is idle, and sends the data only after the channel is in the idle state.
In the traditional cellular system operating on the unlicensed spectrum, the maximum bandwidth of a carrier is 20 MHz, while in the new generation communication system, the bandwidth occupied by a carrier may be larger, for example 100 MHz. In this case, the power consumption of the terminal can be saved by dividing a carrier with a relatively large bandwidth into multiple bandwidth parts. When the terminal is configured with multiple frequency resources such as multiple bandwidth parts, the manner through which the terminal performs data transmission on the frequency resources needs to be clarified. The bandwidth part refers to a resource that is continuous in part of the frequency domain within a carrier. As shown in
As for the application of the new generation communication system on the unlicensed spectrum, since the communication system operating on the unlicensed spectrum needs to first detect whether the channel is idle, multiple channel detection units might be contained for a carrier or a bandwidth part, and channel detection results on different channel detection units may be inconsistent with each other. As a result, part of the control information will not be sent because the channel is unavailable. In the new generation communication system, the transmission of control signaling is carried on a control resource set (CORESET). The configuration of CORESET can be continuous or discontinuous in the frequency domain. A bandwidth part or a carrier including 4 LBT (Listen Before Talk) sub-bands is taken as an example. As shown in
Based on the above wireless communication system, in order to ensure the reception performance of the control information for the user equipment and reduce the detection complexity of the terminal for the control resource set, various embodiments of the method of the present disclosure are proposed.
In step S11, it is determined whether a switching condition for the control resource set is met.
As an implementation manner, whether the switching condition for the control resource set is met is determined as follows:
In some embodiments, the determining that the switching condition for the control resource set is met in response to detecting that a channel in the unlicensed spectrum is successfully occupied by the base station, includes:
In this way, in the case where the user equipment will not receive an explicit instruction sent from the base station regarding whether to switch and which control resource set to be switched to, the user equipment can use the configuration of different control resource sets based on whether the channel is successfully occupied by the base station. Compared with detecting the control signaling blindly, the complexity for the user equipment to detect the control signaling is reduced, the configuration of the control resource set adopted can be changed based on the channel occupancy, and the transmission of the control signaling can be ensured.
In some embodiments, the determining that the switching condition for the control resource set is met in response to detecting that a channel in the unlicensed spectrum is successfully occupied by the base station, includes:
in response to detecting that the channel in the unlicensed spectrum is successfully occupied by the base station, starting timing, and determining that the switching condition for the control resource set is met when a preset time interval is reached.
It should be noted that the preset time interval can be set or adjusted according to design requirements.
In this way, in the case that the user equipment will not receive an explicit instruction sent from the base station regarding the control resource set that is switched to, the user equipment can timely switch the configuration of the control resource set based on the channel occupancy to ensure the transmission of the control signaling.
As another implementation manner, whether the switching condition for the control resource set is met is determined by:
In this way, it is convenient to switch the configuration of the control resource set according to the explicit indication of the base station, and to detect the control signaling on the control resource set indicated by the base station, which reduces the complexity of determining the control resource set by the user equipment.
In some embodiments, the receipt of the switching indication information includes:
The preset information field is an information field with a fixed bit length, or an information field with a configurable bit length.
In this way, it is convenient for the user equipment to determine the configuration information of the control resource set to be switched based on the physical layer signaling in response to the receipt of the physical layer signaling, which reduces the complexity for the user equipment to determine the control resource set.
For example, the physical layer signaling is a downlink control information (DCI) command, and a preset information field of the DCI carries the configuration information of the control resource set to be switched. The user equipment parses the preset information field to obtain the configuration information of the control resource set to be switched when receiving the DCI command.
In some embodiments, the receipt of the switching indication information includes:
Before receiving the signal carrying the orthogonal sequence set, the method further includes:
In this way, it is convenient for the user equipment to determine the configuration information of the control resource set to be switched based on the correspondence when receiving the signal carrying the orthogonal sequence set, which reduces the complexity for the user equipment to determine the control resource set.
In step S12, when the switching condition for the control resource set is met, the configuration of the control resource set on the unlicensed spectrum used for detecting control signaling is switched.
In the technical solutions according to the embodiments of the present disclosure, when the switching condition for the control resource set is met, the UE switches the configuration of the control resource set on the unlicensed spectrum used for detecting control signaling. Through using different control resource set configurations in different states, it is ensured to detect the control signaling on the available control resource set. Compared with blindly detecting the control signaling and using the control resource set, not only the complexity for the user equipment to detect the control resource set is reduced, but also the control information reception of the user equipment is ensured, thus improving the reception performance of the control information.
When the base station has not yet occupied the unlicensed spectrum resources, if it is pre-configured that the user equipment needs to perform the control signaling detection, the user equipment detects the control signaling based on the pre-configured or pre-defined control resource set configuration. For example, the user equipment detects the control signaling based on a manner in which a control resource set is mapped on the entire bandwidth part. After the base station successfully occupies the channel, the user equipment switches the configuration of the control resource set.
In step S21, the configuration of the control resource set for detecting the control signaling on the unlicensed spectrum is determined.
In step S22, switching indication information that is used for triggering the switching of the configuration of the control resource set for detecting the control signaling on the unlicensed spectrum, is transmitted.
In this way, the switching indication information is transmitted to the UE so that the UE may switch the configuration of the control resource set based on the switching indication information, thereby ensuring that the control signaling is detected on the available control resource set. Compared with the manner that the UE blindly detects the control signaling and uses the control resource set, the present application not only reduces the complexity for the user equipment to detect the control resource set, but also ensures the reception of the control information and thus improving the reception performance of the control information.
As an implementation manner, the switching indication information, that is used for triggering the switching of the configuration of the control resource set for detecting the control signaling on the unlicensed spectrum, is transmitted by:
The preset information field is an information field with a fixed bit length, or an information field with a configurable bit length.
For example, the physical layer signaling is a downlink control information (DCI) command, and a preset information field of the DCI carries the configuration information of the control resource set to be switched. The user equipment parses the preset information field to obtain the configuration information of the control resource set to be switched when receiving the DCI command.
As an embodiment, the method further includes:
In this way, it is convenient for the user equipment to determine the configuration information of the control resource set to be switched based on the correspondence when receiving the signal carrying the orthogonal sequence set, which reduces the complexity for the user equipment to determine the control resource set.
As an implementation manner, the switching indication information, that is used for triggering the switching of the configuration of the control resource set for detecting the control signaling on the unlicensed spectrum, is transmitted by:
In this way, it is convenient for the user equipment to determine the configuration information of the control resource set to be switched based on the signal carrying the orthogonal sequence set when receiving the signal carrying the orthogonal sequence set, which reduces the complexity for the user equipment to determine the control resource set.
According to the solutions of the embodiments of the present disclosure, the switching indication information is transmitted to the UE so that the UE may switch the configuration of the control resource set based on the switching indication information, thereby ensuring that the control signaling is detected on the available control resource set. Compared with the manner that the UE blindly detects the control signaling and uses the control resource set, the present application not only reduces the complexity for the user equipment to detect the control resource set, but also ensures the reception of the control information and thus improving the reception performance of the control information.
