[0072] Figure 1 It is a schematic diagram of a 5G application scenario of an embodiment of the present invention.
[0073] like Figure 1 As shown, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.
[0074] It should be understood that the embodiment of the present invention is only exemplified by the 5G communication system 100, but the embodiment of the present invention is not limited thereto. That is to say, the technical solution of the embodiment of the present invention can be applied to various scenarios including 5G communication systems. For example, a hybrid deployment scenario consisting of a 5G communication system and a first communication system, and the like. Among them, the first communication system can be any communication system. For example: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), etc.
[0075] Furthermore, the present invention describes various embodiments in conjunction with network devices and terminal devices.
[0076] The network device 120 may refer to any entity on the network side that is used to send or receive signals, for example, a base station device in a 5G network.
[0077] The terminal device 110 may be any terminal device. Specifically, the terminal device 110 may communicate with one or more core networks via a radio access network (RAN), and may also be referred to as an access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. For example, it may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, etc.
[0078] However, for the above scenario, the primary cell (PCell) under the first communication system cannot operate in an unlicensed frequency band (e.g., LTE). In 5G NR, both the PCell and the secondary cell (SCell) can operate in an unlicensed frequency band. When the base station sends a reference signal (e.g., SSB and CSI-RS) on an unlicensed frequency band, it may encounter a listen-before-talk (LBT) failure and fail to send the reference signal. In this case, how the UE measures these reference signals and how to report them to the base station needs to be solved.
[0079] In order to solve the above technical problems, a method for measurement is provided in an embodiment of the present invention, which configures measurement configuration information for a terminal device through a network device, so that a 5G terminal device on an unlicensed frequency band can measure the received reference signal.
[0080] Figure 2 is a schematic flow chart of a method for measuring according to an embodiment of the present invention.
[0081] Specifically, if Figure 2 As shown, the method includes:
[0082] 210. The network device sends measurement configuration information to the terminal device, where the measurement configuration information includes configuration information of multiple transmission opportunities of the first reference signal in the unlicensed frequency band.
[0083] 220. The network device sends the first reference signal to the terminal device on the multiple transmission opportunities.
[0084] 230. The terminal device determines the cell quality according to the measurement value of the first reference signal received on the multiple transmission opportunities.
[0085] In short, the network device sends measurement configuration information to the terminal device, and sends the first reference signal to the terminal device according to the measurement configuration information.
[0086] It should be understood that the multiple transmission opportunities in the embodiment of the present invention are possible transmission opportunities for sending the first reference signal configured by the network device for the terminal device, and the implementation of the present invention does not specifically limit whether the network device sends the first reference signal to the terminal device on the multiple transmission opportunities. In other words, the network device may send the first reference signal to the terminal device on each of the multiple transmission opportunities, or may send the first reference signal to the terminal device on some of the multiple transmission opportunities, or may not send the first reference signal to the terminal device on the multiple transmission opportunities. Specifically, whether to send the first reference signal can be determined based on the transmission method of the first reference signal, or it can be determined based on the idleness of the channel, and the embodiment of the present invention does not make specific limitations.
[0087] In other words, the terminal device receives measurement configuration information sent by the network device; the terminal device receives the first reference signal on the multiple transmission opportunities and performs measurement based on the configuration information; the terminal device determines the cell quality based on the measurement value of the first reference signal received on the multiple transmission opportunities.
[0088] More specifically, the terminal device may determine the cell quality according to the following formula:
[0089] F n =(1-a)*F n-1 +aM n
[0090] Among them, n represents the number of sampling times, and F n Indicates the cell quality. n represents the measured value, and a represents the weighting coefficient.
[0091] Since the network device may not send the first reference signal to the terminal device on some or all of the multiple transmission opportunities, it is very likely that the terminal device will not be able to measure a certain reference signal. Therefore, the calculation of cell quality also needs to take into account the lack of certain sampling values due to the lack of reference signals.
[0092] In the embodiment of the present invention, when the adopted value is missing, when the above formula is used to calculate the cell quality, the number of sampling times is not increased by 1, that is, the missing sampling value is skipped. For example, when the terminal device does not receive the first reference signal on the first transmission opportunity among the multiple transmission opportunities, the measurement value of the first reference signal received on the second transmission opportunity can be determined as the measurement value of the first reference signal on the first transmission opportunity, and the second transmission opportunity is before the first transmission opportunity.
[0093] That is, in the embodiment of the present invention, when determining the cell quality, the terminal device can effectively improve the accuracy of the cell quality by taking into account the situation where the sampling values are missing.
[0094] It should be understood that the embodiment of the present invention does not limit the specific embodiment of the measurement configuration information, and an exemplary description is given below.
[0095] In one embodiment, Figure 3 As shown, the measurement configuration information can directly configure multiple transmission opportunities of the first reference signal for the terminal device, that is, the terminal device can wait to receive the first reference signal on the multiple transmission opportunities.
[0096] For example, the measurement configuration information may include multiple offset values at fixed time positions. That is, the network device sends the first reference signal to the terminal device on the multiple transmission opportunities determined according to the multiple offset values. Correspondingly, the terminal device only needs to receive the first reference signal sent by the network device on the multiple transmission opportunities determined according to the multiple offset values.
[0097] In another embodiment, Figure 4 As shown, the multiple transmission opportunities may belong to the same time window, and the configuration information includes the configuration information of the multiple transmission opportunities in the time window. That is to say, the network device sends the first reference signal to the terminal device in the multiple transmission opportunities in the same time window by listening before speaking. Accordingly, the terminal device needs to receive the first reference signal that may be sent by the network device in this time window.
[0098] In the embodiment of the present invention, Listen Before Talk (LBT) can be understood as: the station to transmit data first monitors whether there is a carrier on the medium to determine whether there is another station transmitting data. If the medium is idle, the station can transmit data; otherwise, the station will avoid it for a period of time before trying again.
[0099] Optionally, before the network device sends measurement configuration information to the terminal device, the network device may send mapping relationship information to the terminal device, the mapping relationship information including at least one reference signal type and information about a time window corresponding to the at least one reference signal type, the at least one reference signal type including the type of the first reference signal. In other words, the terminal device may receive the mapping relationship information sent by the network device before receiving the measurement configuration information, the terminal device determines the time window corresponding to the first reference signal based on the mapping relationship information and the type of the first reference signal; the terminal device receives the first reference signal and performs measurements on the multiple transmission opportunities within the time window corresponding to the first reference signal based on the configuration information.
[0100] Furthermore, the information of the time window includes a start position of the time window and / or an end position of the time window.
[0101] It should be understood that in the embodiment of the present invention, there is no specific limitation on the manner in which the network device sends the measurement configuration information to the terminal device.
[0102] For example, the network device may send system information to the terminal device, where the system information includes the measurement configuration information.
[0103] For another example, the network device may send a radio resource control (Radio Resource Control, RRC) signaling to the terminal device, where the RRC signaling includes the measurement configuration information.
[0104] It should also be understood that the embodiment of the present invention does not specifically limit the type of the first reference signal. For example, the first reference signal is a synchronization information block (Synchronization Signal Block, SSB) or a channel state information measurement reference signal (Channel State Information Reference Signal, CSI-RS).
[0105] Furthermore, in an embodiment of the present invention, a method for a terminal device to report cell quality is also provided. Specifically, the terminal device sends reporting information to the network device, the reporting information includes indication information and the cell quality obtained by the terminal device based on the first reference signal, and the indication information is used to indicate that the cell quality reported by the terminal device is the cell quality after the terminal device considers the missing sampling value. For the network device, the network device receives the reporting information sent by the terminal device, and determines based on the reporting information that the cell quality reported by the terminal device is the cell quality after the terminal device considers the missing sampling value.
[0106] Figure 5 It is a schematic block diagram of a network device according to an embodiment of the present invention. It should be understood that the network device according to the embodiment of the present invention can be applied to a 5G communication system, that is, a 5G network device or a 5G network element.
