Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method and device for determining an energy detection threshold, a terminal, and a network device. Background Art

[0002] Currently, before sending data on the unlicensed spectrum, the station (base station or terminal) needs to perform a clean channel assessment (CCA) on the channel. The so-called CCA detection is that the station measures the energy on the channel on the unlicensed spectrum within a period of time. If the detected energy is less than or equal to a threshold, the channel is considered idle; otherwise, the channel is considered busy. The threshold mentioned above can be called the Energy Detection Threshold (EDT), which is an important part of CCA detection.

[0003] In the prior art, when determining EDT, the maximum transmission power (ie, Pout) of data transmitted by the access station within (Channel Occupancy Time, COT) is used as an input parameter, and the formula is as follows:

[0004] Wherein, Pmax is the maximum transmission power of the station on a carrier, and Pout is the transmission power of the station.

[0005] When COT sharing occurs, the responding device (RD) (base station or terminal) may also need to perform CCA detection before sending, and also needs to determine EDT. If the responding site uses different maximum transmit powers as input parameters, it will result in different EDTs. Different EDTs mean that different sites have different possibilities of accessing the channel when detecting the same channel interference, which leads to unfair competition for the channel. For example, if the maximum transmit power of the RD is small, it will result in a larger EDT, thereby increasing the chance of access. Therefore, the fairness of the access channel is low. In the COT sharing scenario, new EDT parameters need to be set for the RD to ensure the fairness of the access channel. Summary of the invention

[0069] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0070] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, software, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0071] Reference to "embodiment" herein means that a particular feature, structure or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments. The embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0072] In the prior art, when determining EDT, the maximum transmission power (ie, Pout) of data transmitted by the access station within (Channel Occupancy Time, COT) is used as an input parameter, and the formula is as follows:

[0073] Wherein, Pmax is the maximum transmission power of the station on a carrier, and Pout is the transmission power of the station.

[0074] When COT sharing occurs, the responding device (RD) (base station or terminal) may also need to perform CCA detection before sending, and also needs to determine EDT. If the feedback site uses different maximum transmit powers as input parameters, it will result in different EDTs. Different EDTs mean that different sites have different possibilities of accessing the channel when detecting the same channel interference, which leads to unfair competition for the channel. For example, if the maximum transmit power of the feedback site is small, it will result in a larger EDT, thereby increasing the chance of accessing the channel. Therefore, the fairness of the access channel is low. In the COT sharing scenario, new EDT parameters need to be set for the feedback site to ensure fairness in accessing the channel.

[0075] Based on the above problems, an embodiment of the present invention provides a method for determining an energy detection threshold, which is described in detail as follows.

[0076] The embodiments of the present application describe various embodiments in combination with a terminal and a network device, which are described in detail below.

[0077] Specifically, the terminal in the embodiment of the present application may be a user equipment (UE), an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, an intelligent terminal, a wireless communication device, a user agent or a user device. The terminal may also 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 relay device, a vehicle-mounted device, a wearable device, a terminal in a next-generation communication system such as an NR network or a terminal in a future-evolved public land mobile communication network (PLMN), etc., without specific limitation.

[0078] Furthermore, the terminal can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can be deployed on the water surface (such as ships); it can also be deployed in the air (such as airplanes, balloons and satellites).

[0079] Furthermore, the terminal may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a vehicle-mounted device in self-driving, a wireless terminal device in remote medical, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home, etc.

[0080] Specifically, the network device in the embodiment of the present application can be a base station (base transceiver station, BTS) in a global system of mobile communication (GSM) communication system or a code division multiple access (CDMA) communication system, a base station (nodeB, NB) in a wideband code division multiple access (WCDMA) communication system, an evolutionary base station (eNB or eNodeB) in a long-term evolution (LTE) communication system, or a base station (gNB) in a new radio (NR) communication system. The network device can also be an access point (AP) in a wireless local area network WLAN, a relay station, a network device in a future evolved PLMN network, or a network device in an NTN communication system, etc.

[0081] It should be noted that in some network deployments, the gNB may include a centralized unit (CU) and a distributed unit (DU), and the gNB may also include an active antenna unit (AAU). Among them, the CU can implement some functions of the gNB, and the DU can also implement some functions of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, and implementing the functions of the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer; the DU is responsible for processing the physical layer protocol and real-time services, and implementing the functions of the radio link control (RLC) layer, the medium access control (MAC) layer and the physical (PHY) layer. In addition, the AAU implements some physical layer processing functions, RF processing and related functions of active antennas. Since the information of the RRC layer will eventually become the information of the PHY layer, or be converted from the information of the PHY layer, the high-level signaling (such as the RRC layer signaling) can be considered to be sent by the DU, or by the DU+AAU. It is understandable that the network device may include one or more of a CU node, a DU node, and an AAU node. In addition, the CU may be classified as a network device in an access network (RAN), or may be classified as a network device in a core network (CN), without specific limitation.

[0082] See also Figure 1 , Figure 1 Schematic diagram of the architecture of a communication system provided by an embodiment of the present application. Figure 1 As shown, the communication system includes a network device 110 and a terminal 120, and b=3 is used as an example for explanation. When the wireless communication network includes a core network, the network device 110 can also be connected to the core network. The network device 110 can also communicate with an Internet Protocol (IP) network, such as the Internet, a private IP network, or other data networks. The network device 110 can provide wireless access services for the terminal 120. Each network device 110 corresponds to a service coverage area. The terminal 120 entering the area can communicate with the network device 110 through wireless signals. In addition, the network devices 110 can also communicate with each other.

[0083] based on Figure 1In the system architecture shown, when the terminal 120 or the network device 110 acts as an access site, it is possible to obtain a first power parameter, the first power parameter being used to indicate the quotient of a first parameter and a second parameter, the first parameter being the maximum transmit power of the network device on the carrier, and the second parameter being the maximum transmit power of the network device when transmitting data during the current channel occupancy time; obtain a second power parameter, the second power parameter being used to indicate the quotient of a third parameter and a fourth parameter, the third parameter being the maximum transmit power of the terminal on the carrier, and the fourth parameter being the maximum transmit power of the terminal when transmitting data during the current channel occupancy time; if the first power parameter is less than the second power parameter, the energy detection threshold of the current channel is determined according to the first power parameter. Determining the energy detection threshold based on the first power parameter and the second power parameter expands the mechanism for determining the energy detection threshold, while ensuring the fairness of channel access. It should be noted that Figure 1 The form and quantity of the network device 110 and the terminal 120 shown in the figure are for example only and do not constitute a limitation on the embodiments of the present application.

[0084] In combination with the above description, the embodiment of the present application provides a flow chart of a method for determining an energy detection threshold, which is applied to a terminal, and the network device shares the current channel occupancy time with the terminal as an application scenario, please refer to Figure 2 The method comprises:

[0085] S201. The terminal obtains a first power parameter.

[0086] The first power parameter is used to indicate the quotient of a first parameter and a second parameter, wherein the first parameter is the maximum transmission power of the network device on the carrier, and the second parameter is the maximum transmission power of the network device when transmitting data during the current channel occupancy time.

[0087] In addition, the first power parameter is one of the parameters used by the network device to determine the energy detection threshold; the energy detection threshold for determining the channel is determined based on the first power parameter, CCA detection bandwidth and other parameters to determine the energy detection threshold; the first parameter is the upper limit of the transmit power on the carrier, and its value can be 55dBm, 43dBm, 33dBm, 23dBm, etc.; the value of the first parameter can refer to the value of the transmit power of the base station (Base Station) in TS38.104; the second parameter is less than or equal to the first parameter.

[0088] Optionally, the terminal may acquire the first power parameter in the following manner: the terminal receives the first parameter and the second parameter from the network device; and the terminal determines a quotient of the first parameter and the second parameter as the first power parameter.

[0089] Specifically, the implementation method in which the terminal receives the first parameter from the network device may be but is not limited to: the terminal receives the first parameter from the network device through at least one of system information block (SIB) information, public radio resource control (RRC) signaling, and terminal-specific UE specific RRC signaling.

[0090] It should be noted that the embodiment of the present application considers that the network device sends a first parameter to the terminal through at least one of SIB information, RRC signaling, and UE-specific RRC signaling, so that the terminal determines the energy detection threshold based on the first parameter, thereby realizing the expansion of the energy detection threshold determination mechanism.

[0091] Optionally, the terminal may receive the first parameter from the network device in the following implementation manner: the terminal receives first downlink control information (Downlink Control Information, DCI) from the network device to receive the first parameter indicated by the first DCI.

[0092] It should be noted that the embodiment of the present application considers that the network device indicates the first parameter to the terminal through the first DCI, so that the terminal determines the energy detection threshold mechanism based on the first parameter, thereby realizing the expansion of the energy detection threshold determination mechanism.

[0093] The first DCI includes common downlink control information or UE specific downlink control information.

[0094] As a possible implementation manner, the first parameter is indicated by a first field in the first DCI, and the first field consists of one or more bits in the first DCI.

[0095] As another possible implementation, the first parameter is indicated by a second field in the first DCI, and the second field is also used to indicate the listen-before-talk LBT type and / or the channel access priority level CAPC.

[0096] It is understandable that bits can be saved by indicating the first parameter in conjunction with the LBT type and / or CAPC.

[0097] Specifically, the terminal may receive the second parameter from the network device in the following manner: the terminal receives the second parameter indicated by the second downlink control information DCI from the network device.

[0098] It should be noted that the embodiment of the present application considers that the network device indicates the second parameter to the terminal through the second DCI, so that the terminal determines the energy detection threshold mechanism based on the second parameter, thereby realizing the expansion of the energy detection threshold mechanism.

[0099] The second DCI includes common downlink control information or UE specific downlink control information.

[0100] As a possible implementation manner, the second parameter is indicated by a third field in the second DCI, and the third field consists of one or more bits in the second DCI.

[0101] As another possible implementation,

[0102] The second parameter is indicated by the fourth field in the second DCI, and the fourth field is also used to indicate the listen-before-talk LBT type and / or the channel access priority level CAPC.

[0103] It is understandable that bits can be saved by indicating the second parameter in conjunction with the LBT type and / or CAPC.

[0104] It should be further explained that the second parameter and the first parameter can be indicated by different DCIs. In this case, the LBT type can be indicated jointly with the second parameter, and the CAPC can be indicated jointly with the first parameter; the LBT type and the CAPC can also be indicated jointly with the second parameter, and the first parameter can be indicated alone; the LBT type and the CAPC can also be indicated jointly with the first parameter, and the second parameter can be indicated alone; the LBT type and the CAPC can also be indicated jointly with the first parameter, and the CAPC can be indicated jointly with the first parameter; and so on, without further explanation.

[0107] Specifically, the implementation manner in which the terminal receives the first power parameter from the network device may be but is not limited to: the terminal receives the first power parameter from the network device through at least one of SIB information, common RRC signaling and UE specific RRC signaling.

[0108] It should be noted that the embodiment of the present application considers that the network device determines the quotient of the first parameter and the second parameter as the first power parameter, and then sends the first power parameter to the terminal through at least one of SIB information, RRC signaling, and UE-specific RRC signaling, so as to enable the terminal to determine the energy detection threshold based on the first power parameter, thereby realizing the expansion of the mechanism for determining the energy detection threshold.

[0109] Specifically, the terminal may receive the first power parameter from the network device in the following manner: the terminal receives the first power parameter indicated by the third DCI by receiving the third DCI from the network device.

[0117] Among them, the second power parameter is one of the parameters used by the terminal to determine the energy detection threshold; the energy detection threshold for determining the channel is the threshold for energy detection determined based on the second power parameter, CCA detection bandwidth and other parameters; the third parameter is the upper limit of the transmit power on the carrier, and its value can be 25dBm, 23dBm, 21dBm, 19dBm, etc.; the value of the third parameter can refer to the value of the terminal in TS38.101-1 / 101-2 / 101-3; the fourth parameter is less than or equal to the third parameter.

[0118] Furthermore, the terminal acquires the second power parameter in the following manner: the terminal determines the third parameter and the fourth parameter; and the terminal determines the quotient of the third parameter and the fourth parameter as the second power parameter.

[0119] S203: If the first power parameter is less than the second power parameter, the terminal determines an energy detection threshold of a current channel according to the first power parameter.

[0154] The following are two examples based on the premise that the network device is a base station and the base station shares the current channel occupation time COT with the terminal.

[0155] Example 1:

[0156] For base stations.

[0157] After the base station's Clean Channel Assessment (CCA) is successful and all CCA detections are completed, the base station occupies the channel and sends data. When the base station determines the Energy Detection Threshold (EDT) during the clean channel assessment process, the base station's power parameter Pmax_gNB is recorded as the first parameter, which is the maximum transmit power of the base station on the carrier, and the base station's power parameter Pout_gNB is recorded as the second parameter, which is the maximum transmit power of the base station during the current channel occupancy time. The second parameter is less than or equal to the first parameter.

The terminal determines the second power parameter according to the third parameter and the fourth parameter, and the determination method may be that the second power parameter is equal to the quotient of the third parameter and the fourth parameter. The terminal compares the first power parameter and the second power parameter. If the first power parameter is less than the second power parameter, the terminal uses the first power parameter to calculate the energy detection threshold, that is, the terminal determines the energy detection threshold of the current channel according to the first power parameter.
