[0068] Figure 6 This is a block diagram illustrating an apparatus for frequency hopping configuration according to an exemplary embodiment. Detailed Implementation

[0069] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0070] In communication systems, for IoT services with low data rates and high latency scenarios (such as meter reading and environmental monitoring), two main technologies have been proposed: MTC and NB-IoT. Currently, NB-IoT can support speeds of a few hundred kilobytes per second (kbps), while MTC can support speeds of a few megabytes per second (Mbps). However, with the continuous development of IoT services (such as monitoring, smart homes, wearable devices, and industrial sensor detection), speeds of tens to hundreds of megabytes per second (Mbps) are generally required, and latency requirements are also increasing. Therefore, in communication systems, MTC and NB-IoT technologies can no longer meet the current requirements of IoT services. Consequently, a new user equipment (UE) has been proposed to be designed in the new radio interface of communication systems to cover the service requirements of mid-range IoT devices that require speeds of tens to hundreds of megabytes per second and have relatively high latency. Currently, in the 3rd Generation Partnership Project (3GPP) standardization, the UE used to cover the service requirements of mid-range IoT devices that require speeds of tens to hundreds of megabytes per second and have relatively high latency is called Reduced Capability UE (or Redcap terminal, or NR-lite).

[0071] On the other hand, NR-lite generally needs to meet requirements such as low cost, low complexity, a certain degree of coverage enhancement, and power saving. However, new radio communication technologies are designed for high-end terminals with high speed and low latency, and cannot meet the above requirements of NR-lite. Therefore, it is necessary to modify the current new radio communication technology to meet the above requirements of NR-lite. For example, to meet the requirements of low cost and low complexity, the radio frequency (RF) bandwidth of the new radio IoT can be limited (e.g., limited to 5MHz or 10MHz; or the size of the NR-lite buffer can be limited), thereby limiting the size of each received transmission block, etc. Furthermore, to meet the requirements of power saving, the communication process can be simplified to reduce the number of times NR-lite users need to detect the downlink control channel.

[0072] However, due to the limitations of Redcap terminals, their coverage capabilities are also restricted. Related technologies employ coverage enhancement methods, such as repetitive transmission (where repetitive transmission refers to transmitting the same content in the time domain), and further introduce frequency hopping transmission based on repetitive transmission. In other words, this allows the repetitive transmission of the same information in different time domains to occur on different frequency bands.

[0073] Currently, the frequency switching time is determined based on the number of repetitions for each transmitted channel. However, for Redcap terminals, since multiple channels may be transmitting within a frequency band, if the frequency switching time is still determined based on the number of repetitions for each transmitted channel as in related technologies, the determined frequency band location and frequency switching time will be different. Figure 1 This is a schematic diagram illustrating the determination of frequency band location and frequency switching time points in related technologies according to an exemplary embodiment. According to related technologies, the terminal's physical downlink control channel (PDCCH) and physical downlink shared channel (PDSCH) are transmitted two subframes apart. For example... Figure 1 As shown, within the same terminal channel (BW), the physical downlink shared channel begins frequency hopping in the fourth subframe, but the physical downlink control channel only begins frequency hopping in the sixth subframe. Therefore, if the frequency band location and frequency switching time are determined according to the relevant technologies, the terminal will be unable to receive the content transmitted through the channel normally, inevitably resulting in the loss of part of the transmitted content of the terminal's physical downlink control channel or part of the transmitted content of the physical downlink shared channel.

[0074] To address the problems mentioned above in the related technologies, this disclosure provides a frequency hopping configuration method. The frequency hopping configuration method provided by this disclosure can unify the frequency band switching time and frequency band location of different channels, effectively avoiding the loss of transmitted content by the terminal during frequency hopping. Figure 2 This is a communication system architecture diagram of a network device and a terminal according to an exemplary embodiment. The frequency hopping configuration method provided in this disclosure can be applied to... Figure 2 The communication system architecture diagram shown is as follows. Figure 2 As shown, the terminal receives the transmission content sent by the network device on the terminal's physical downlink control channel and physical downlink shared channel.

[0075] Understandable, Figure 2 The network devices and terminal communication system shown are for illustrative purposes only. A wireless communication system may also include other network devices, such as core network equipment, wireless relay equipment, and wireless backhaul equipment. Figure 2Not shown in the diagram. This disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0076] It is further understood that the wireless communication system of this disclosure is a network providing wireless communication functionality. The wireless communication system can employ different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single-carrier frequency division multiple access (SC-FDMA), and carrier sense multiple access with collision avoidance. Based on factors such as capacity, speed, and latency, networks can be categorized as 2G networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks. 5G networks can also be referred to as New Radio (NR). For ease of description, this disclosure may sometimes simply refer to the wireless communication network as a network.

[0077] Furthermore, the network device involved in this disclosure can also be referred to as a wireless access network device. This wireless access network device can be: a base station, an evolved Node B (eB) base station, a home base station, an access point (AP) in a Wireless Fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc. It can also be a gNB in ​​an NR system, or a component or part of a base station. When it is a vehicle-to-everything (V2X) communication system, the network device can also be an in-vehicle device. It should be understood that the specific technologies and device forms used in the embodiments of this disclosure are not limited.

[0078] Furthermore, the terminal involved in this disclosure can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., and is a device that provides voice and / or data connectivity to a user. For example, a terminal can be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include: smartphones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be an in-vehicle device. It should be understood that the embodiments of this disclosure do not limit the specific technology or specific device form adopted by the terminal.

[0079] Figure 3 This is a flowchart illustrating a frequency hopping configuration method according to an exemplary embodiment, such as... Figure 3 As shown, the frequency hopping configuration method includes the following steps.

[0080] In step S11, frequency hopping related parameters are determined.

[0081] In step S12, data is transmitted on at least one frequency band resource according to the frequency hopping related parameters.

[0082] In this embodiment of the disclosure, for the same terminal, relevant parameters for frequency hopping are determined based on the terminal's capabilities and transmission requirements. These parameters may include the frequency band location for frequency hopping. Data is transmitted on the frequency band resources according to the determined frequency band location parameters.

[0083] In embodiments of this disclosure, data is transmitted on no fewer than two frequency bands based on frequency hopping parameters.

[0084] In the embodiments of this disclosure, there may be multiple frequency band positions for frequency hopping, which may belong to different frequency bands.

[0085] In embodiments of this disclosure, frequency hopping related parameters may also include any one or more parameters such as bandwidth, subcarrier spacing of the frequency band, and transmission parameters associated with the frequency band (e.g., relative frequency domain position, number of symbols occupied by the transmitted content, duration, channel mapping method, transmission method, etc.).

[0086] In embodiments of this disclosure, if two or more different channels are transmitted in the same frequency band, the frequency hopping method for different transmission channels in the same frequency band is performed in one of the following ways.

[0087] At least two different transmission channels in the same frequency band perform frequency hopping based on the same frequency hopping parameters; or

[0088] At least two different transmission channels in the same frequency band perform frequency hopping based on partially identical frequency hopping parameters.

[0089] In other words, the frequency hopping parameters of different transmission channels in the same frequency band are unified or partially unified to achieve the same frequency band switching time point and frequency band position for multiple transmission channels.

[0090] In one embodiment of this disclosure, for at least two different downlink transmission channels corresponding to the same terminal in the same frequency band, the same frequency hopping parameters are used in a single frequency hopping operation. For example, if the frequency hopping parameters of the physical downlink control channel and the physical downlink shared channel are determined to be the same in a single frequency hopping operation, then during the frequency hopping process of the physical downlink control channel and the physical downlink shared channel, the frequency band switching time point and frequency band position of the physical downlink control channel and the physical downlink shared channel are the same. Therefore, the terminal can simultaneously receive the transmission content of the physical downlink control channel and the physical downlink shared channel, avoiding the loss of transmission content due to different frequency band switching time points and frequency band positions corresponding to different transmission channels.

[0091] For the same uplink channel of the same terminal (e.g., physical uplink control channel and physical uplink shared channel), at least two different transmission channels corresponding to the same uplink frequency band have the same frequency hopping parameters in a single frequency hopping operation. For example, if the frequency hopping parameters of the physical uplink control channel and the physical uplink shared channel are determined to be the same in a single frequency hopping operation, then the frequency band switching time point and frequency band position of the physical uplink control channel and the physical uplink shared channel are the same during the frequency hopping process. Therefore, the terminal can simultaneously transmit the transmission content of the physical uplink control channel and the physical uplink shared channel, thereby avoiding the loss of transmission content due to different frequency band switching time points and frequency band positions corresponding to different transmission channels.

[0092] In the embodiments of this disclosure, other frequency hopping parameters besides the switching time point and frequency band location can be the same or different, and can be set accordingly based on different network states and protocols. No limitations are imposed in this disclosure. In the embodiments of this disclosure, the frequency hopping related parameters include at least one set of parameters, and the parameter set includes at least one of the following:

[0093] Frequency band switching time-related parameters, the target frequency band location, and the time granularity of frequency hopping.

[0094] That is, a set of parameters may include frequency band switching time-related parameters and the frequency band location of the target frequency band to be switched; or a set of parameters may include the frequency band location of the target frequency band to be switched and the frequency hopping time granularity; or a set of parameters may include frequency band switching time-related parameters, the frequency band location of the target frequency band to be switched, and the frequency hopping time granularity, etc. In other words, different parameter sets may include different frequency hopping related parameters. In the embodiments of this disclosure, there may be multiple target frequency band locations for frequency hopping, which may belong to different frequency bands. All target frequency bands have the same bandwidth and / or subcarrier spacing.

[0095] In the embodiments of this disclosure, if there are multiple target frequency bands, that is, two or more, then for the same transmission channel, the corresponding transmission parameters in the multiple target frequency bands are the same.

[0096] In this embodiment of the disclosure, the transmission parameters include at least one of the following:

[0097] The frequency resources occupied by the transmission channel, its relative frequency domain position in the target frequency band, transmission duration, resource mapping method, and transmission method are all considered. For example, the frequency domain position of the transmission resources of the physical downlink shared channel in the original frequency band corresponds to the frequency domain position of the transmission resources in the target frequency band. That is, the frequency domain position of the transmission resources in the frequency band before frequency hopping corresponds to the determined frequency domain position of the transmission resources in all target frequency bands. Furthermore, the number of symbols occupied by the transmission resources is the same before and after frequency hopping. For example, if the transmission resources occupied 4 symbols before frequency hopping, then after hopping to the target frequency band, the number of symbols occupied by the transmission resources in the target frequency band is also 4 symbols. And as mentioned above, the frequency domain position of the 4 symbols occupied by the transmission resources in the target frequency band corresponds to the frequency domain position of the 4 symbols occupied by the transmission resources in the original frequency band.

[0098] For example, for the physical downlink control channel, the configuration of the control-resource set (CORESET) is the same in each frequency band. In other words, the relative frequency domain position, duration, PDCCH mapping method, transmission method, etc. of the physical downlink control channel in the frequency band configuration of frequency hopping are the same as the configuration of the same set of physical resources in the original frequency band.

[0099] In some embodiments of this disclosure, based on a predetermined number and location of frequency bands for terminal frequency hopping, when the terminal receives a first indication message, it performs a frequency hopping operation according to the frequency hopping method in the first indication message. For ease of description, this disclosure refers to the message used to indicate the frequency hopping method of the terminal as the first indication message.

[0100] In this embodiment of the disclosure, the frequency hopping method can also be referred to as the frequency hopping order, and the first indication message can be determined based on a predefined (e.g., a pre-set rule).

[0101] In the embodiments of this disclosure, there can be multiple target frequency bands for frequency hopping, and these target frequency bands can belong to different frequency bands. For example, based on the target frequency band position, the frequency hopping can proceed sequentially from a low-frequency frequency band position to a high-frequency frequency band position. After reaching the highest frequency frequency band position, the frequency hopping continues sequentially from the highest frequency frequency band position to the lowest frequency frequency band position, eventually returning to the lowest frequency frequency band position.

[0102] In another example, if there are multiple frequency bands for frequency hopping, the frequency hopping pattern can be determined based on the signaling instructions received by the terminal. The signaling can instruct the terminal to perform frequency hopping according to the frequency hopping rules specified therein. These frequency hopping rules can be determined based on the actual situation.

[0103] In some embodiments of this disclosure, based on a predetermined number and location of frequency bands for terminal frequency hopping, the duration of receiving transmission content from different channels or the duration of transmitting transmission content from different channels in each frequency band can be further determined. In other words, in embodiments of this disclosure, the frequency hopping time granularity for receiving transmission content from different channels or the frequency hopping time granularity for transmitting transmission content from different channels in each frequency band is determined. The duration of receiving transmission content from different channels or the duration of transmitting transmission content from different channels in each target frequency band can be determined based on absolute time. It should be understood that absolute time can be one or more of the following: the number of system subframes, the number of time slots, the number of system symbols, etc.

[0104] In this embodiment of the disclosure, the terminal determines the frequency band switching time based on the received second indication message. For ease of description, the message used to indicate the time of the terminal's frequency band switching is referred to as the second indication message. The second indication message includes the frequency switching period.

[0105] In this embodiment of the disclosure, the terminal can determine the second indication message based on the broadcast message of the network-side device, or it can determine the second indication message based on the dedicated signaling sent by the network-side device.

[0106] In this embodiment, the frequency band switching time determined by the terminal based on the second indication message can also be determined based on absolute time. As mentioned above, absolute time can include one or more of the following: the number of system subframes, the number of system time slots, and the number of system symbols. Therefore, the frequency band switching time for different frequency bands can also be determined based on absolute time using a system subframe number, system time slot number, or system symbol as the frequency band switching time. In other words, the frequency band switching time is determined based on the duration of the terminal receiving or sending transmission content from different channels, as determined by absolute time. Therefore, the frequency band switching time can be at least one of the following:

[0107] System subframe number, system time slot number, system symbol.

[0108] For example, when the absolute time of the terminal satisfies the predefined subframe equation, frequency band cutting, i.e., frequency band switching, can be performed. The predefined subframe equation is (SFN + subframe) mod N = offset. It should be noted that N is the time granularity or period of the switching, which is notified by higher-layer signaling or predefined. The value of offset can be fixed in the preset, for example, set to a fixed offset = 0, or the offset can be configured based on the physical higher layer. SFN + subframe represents the absolute time of the terminal, where SFN is the system frame and subframe is a subframe within the system frame.

[0109] In some embodiments of this disclosure, the terminal receives a third indication message to determine whether to activate or deactivate the frequency hopping function. For ease of description, this disclosure refers to the indication message used to determine whether to activate or deactivate the frequency hopping function as a third indication message.

[0110] In this embodiment of the disclosure, if the third indication message received by the terminal is to activate the frequency hopping function, the terminal further determines the relationship between the frequency band where the content transmitted on the current different transmission channels is located and the frequency band of the frequency hopping.

[0111] In one implementation, if the frequency band where the content being transmitted on different transmission channels is located belongs to a defined frequency band for frequency hopping, then the terminal responds to the frequency band for frequency hopping including the frequency band where the content being transmitted on different transmission channels is located, and performs frequency hopping according to the frequency hopping method in the received first instruction message indicating the frequency hopping method, based on the frequency band where the content being transmitted on different transmission channels is located.

[0112] Alternatively, in another implementation,

[0113] If the frequency band containing the content being transmitted on different transmission channels does not belong to the determined frequency hopping band, the terminal, in response to the frequency hopping band not including the frequency band containing the content being transmitted on different transmission channels, determines the frequency band containing the content being transmitted on different transmission channels to hop to the designated frequency band based on the received third indication message and the predetermined frequency hopping band and its position. Then, it performs frequency hopping according to the frequency hopping method in the received first indication message with a frequency hopping method. Specifically, the frequency band containing the content being transmitted on different transmission channels can choose to hop to the frequency band with the lowest frequency among the frequency hopping bands, and then perform frequency hopping according to the frequency hopping method in the received first indication message with a frequency hopping method. Alternatively, the frequency band containing the content being transmitted on different transmission channels can also choose to hop to the frequency band with the highest frequency among the frequency hopping bands, and then perform frequency hopping according to the frequency hopping method in the received first indication message with a frequency hopping method. Alternatively, the frequency band where the content being transmitted on the current different transmission channels is located can be selected to hop to the preset first frequency hopping band in the frequency hopping band, and then frequency hopping can be performed according to the frequency hopping method in the received first instruction message with frequency hopping method.

[0114] In this embodiment of the present disclosure, if the third instruction message received by the terminal is to disable the frequency hopping function, the terminal will disable the frequency hopping function according to the received third instruction message, and the terminal can temporarily stop performing the frequency hopping operation.

[0115] Based on the same concept, embodiments of this disclosure also provide a frequency hopping configuration device.

In conjunction with the units and algorithm steps of the various examples disclosed in this disclosure, this disclosure can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed by hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of the technical solutions of this disclosure.
