Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, and more particularly, to a method and apparatus for wireless access. BACKGROUND

[0002] In a communication process, since the service in the application scenario corresponding to the machine-type terminal device does not have a high requirement on the data transmission rate, the implementation specification can be reduced, thereby reducing the implementation cost. On the other hand, reducing the implementation cost of the machine-type terminal device also helps to expand the market of the machine-type terminal device and promote the development of the Internet of Things market.

[0003] However, in some scenarios, such as a new radio (NR) system, there is no interaction between the base station and the corresponding cell in the initial access stage, so the base station cannot obtain the type of the terminal device, such as the machine-type terminal device, and thus cannot determine the bandwidth capability of the terminal device. At the same time, since the base station cannot identify each machine-type terminal device, it is impossible to configure the data transmission frequency resource for each machine-type terminal device through the dedicated signaling of the terminal device, thereby causing an overload on the data transmission frequency resource in the non-connected state. In addition, the uplink initial bandwidth part can be used for the physical uplink shared channel for transmitting information 3 and the physical uplink control channel for transmitting the hybrid automatic repeat request feedback in the random access process, wherein the hybrid automatic repeat request feedback is the feedback for information 4 in the initial access process. In addition, the physical random access channel resource in the initial access process must also be transmitted in the uplink initial bandwidth part. Further, the terminal device can also ensure the data transmission performance between the terminal device and the base station in the connection process through the physical uplink control channel frequency hopping and the physical uplink shared channel frequency hopping, wherein the frequency range of the physical uplink control channel frequency hopping and the frequency range of the physical uplink shared channel frequency hopping also need to be ensured in the uplink initial bandwidth part. Therefore, it is necessary to define the frequency range including the above-mentioned data transmission resource and the frequency hopping resource for the NR terminal device, so as to ensure the establishment of the data transmission connection with the base station. SUMMARY

[0004] The embodiments of the present application provide a method and apparatus for wireless access, which can ensure the performance of the non-connected state data transmission while ensuring a certain peak rate of the uplink data transmission, thereby reducing the influence on the data transmission performance of other terminal devices.

[0091] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0092] The Fifth-Generation (5G) mobile communication technology New Radio (NR) is a global 5G standard based on the Orthogonal Frequency Division Multiplexing (OFDM) air interface design, and is also a very important basis for the next generation of cellular mobile technology. The 5G technology has a very diverse business, which can be oriented to Enhanced Mobile Broadband (eMBB) business, Ultra-Reliability Low-Latency Communication (URLLC) business, and Massive Machine-Type Communication (mMTC) business. The mMTC business may be, for example, Industrial Wireless Sensor Network (IWSN) business, Video Surveillance business, and Wearables business.

[0093] Machine-type terminal devices often have higher requirements for cost and power consumption. For example, machine-type terminal devices are generally implemented at low cost because the data transmission rate requirement of the application scenarios corresponding to the machine-type terminal devices is not high. For example, the data transmission rate carried by the sensors in the IWSN is not greater than 2 Mbps, which is sufficient to meet the IWSN business. The data transmission rate carried by the economic video surveillance camera is generally 2-4 Mbps. The terminal device in the wearable business, such as a smart watch, has a downlink peak rate of not more than 150 Mbps and an uplink peak rate of not more than 50 Mbps, which is much lower than the peak rate of the NR legacy terminal device (such as the NR eMBB terminal device). Based on this, the machine-type terminal device can reduce the implementation specification relative to the NR legacy terminal device, thereby reducing the implementation cost. On the other hand, reducing the implementation cost of the machine-type terminal device also helps to expand the market of the machine-type terminal device and promote the development of the Internet of Things market. At present, 3GPP has started research on low-capability terminal devices (NR reduced capability, NR RedCap) in the NR system (reference: RP-193238), aiming at the growing Internet of Things market, such as the IWSN, video surveillance, and wearable business mentioned above, to design a terminal device that meets the performance requirements of the Internet of Things market and has low cost / low implementation complexity, so as to expand the application of the NR system in the Internet of Things market. For ease of description, in the subsequent part of the text, NR RedCap UE is taken as an example for description.

[0094] One way to reduce the cost of terminal equipment is to reduce its channel bandwidth, or in other words, its bandwidth capability. Specifically, the bandwidth capability of an NR RedCap UE can be significantly less than that of an NR legacy terminal equipment. Currently, NR Legacy terminal equipment, such as versions Rel-15 / Rel-16, must have a bandwidth capability of 100MHz. However, from the perspective of receiving the initial access signal from the NR base station and connecting to the NR system, the bandwidth capability of an NR RedCap UE can be as low as 20MHz. In some NR system configurations, the bandwidth capability of the NR RedCap UE can be further reduced, for example, to 5MHz or 10MHz. In this case, the NR RedCap UE can still connect to the NR system. A bandwidth capability of no more than 20MHz, compared to 100MHz, can significantly reduce the cost of the RedCap UE.

[0095] The technical solutions of this application can be applied to various communication systems, such as: 5th generation (5G) systems or new radio (NR), long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, universal mobile telecommunication system (UMTS), etc. The technical solutions of this application can also be applied to device-to-device (D2D) communication, etc.

[0096] To facilitate understanding of the embodiments of this application, firstly, in conjunction with Figure 1 and Figure 2 The communication system applicable to the embodiments of this application is described in detail.

[0097] Figure 1 This is a schematic diagram of a wireless communication system 100 applicable to embodiments of this application. As shown, the wireless communication system 100 may include at least one network device, such as... Figure 1 The network device 111 shown, the wireless communication system 100 may also include at least one terminal device, such as Figure 1 The terminal devices 121 to 123 shown are network devices and terminal devices. Both network devices and terminal devices can be configured with multiple antennas, and network devices and terminal devices can communicate using multi-antenna technology.

[0098] In the communication between the network device and the terminal device, the network device can manage one or more cells, and each cell can serve at least one terminal device. In a possible implementation, the network device 111 and the terminal devices 121-123 form a single-cell communication system, without loss of generality, the cell is denoted as cell #1. The network device 111 can be a network device in the cell #1, or in other words, the network device 111 can serve a terminal device (for example, the terminal device 121) in the cell #1.

[0099] It should be noted that the cell can be understood as an area within the wireless signal coverage of the network device.

[0100] Figure 2 Another schematic diagram of a wireless communication system 200 applicable to the embodiments of the present application is shown. As shown in the figure, the technical solutions of the embodiments of the present application can also be applied to D2D communication. The wireless communication system 200 includes a plurality of terminal devices, for example, the terminal devices 201-203 in the cell #1. The terminal devices 201-203 can directly communicate with each other. For example, the terminal devices 201 and 202 can separately or simultaneously send data to the terminal device 203. Figure 2

[0101] It should be understood that the above Figure 1 and Figure 2 are only exemplary descriptions, and the present application is not limited thereto. For example, the embodiments of the present application can also be applied to a random access scenario (such as a 5G NR random access procedure).

[0102] ​It should also be understood that the network device in the wireless communication system can be any device with wireless transceiver function. The device includes, but is not limited to, an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., a Home eNodeB or a Home Node B, HNB), a baseband unit (BBU), 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., and can also be a gNB or a TP in a 5G (e.g., NR) system, one or a group of (including multiple antenna panels) antenna panels of a base station in a 5G system, or a network node constituting a gNB or a TP, such as a baseband unit (BBU) or a distributed unit (DU), etc.

[0103] In some deployments, a gNB can include a centralized unit (CU) and a DU. The gNB can also include an active antenna unit (AAU). The CU implements part of the functions of the gNB, and the DU implements part of the functions of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, implementing the radio resource control (RRC), and the functions of the packet data convergence protocol (PDCP) layer. The DU is responsible for processing the physical layer protocol and real-time services, implementing the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. The AAU implements part of the physical layer processing functions, radio frequency processing, and related functions of the active antenna. Since the information of the RRC layer eventually becomes the information of the PHY layer, or is transformed from the information of the PHY layer, under this architecture, high-layer signaling, such as RRC layer signaling, can also be considered as being sent by the DU, or by the DU+AAU. It can be understood that the network device can be a device including one or more of the CU node, the DU node, and the AAU node. In addition, the CU can be divided into a network device in the radio access network (RAN), or can be divided into a network device in the core network (CN), which is not limited in the present application.

[0104] It should also be understood that the terminal device in the wireless communication system can also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user apparatus. The terminal device in the embodiments of the present application can 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 in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical treatment, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present application do not limit the application scenarios.

[0105] In order to facilitate understanding of the embodiments of the present application, the following first briefly introduces several terms involved in the present application.

[0106] 1. Physical Uplink Control CHannel

[0107] The physical uplink control channel (PUCCH) is used to carry uplink control information. Compared with LTE, NR PUCCH supports five different formats. According to the number of symbols occupied in the time domain, it can be divided into short format and long format. The short format occupies 1-2 symbols and can carry 1-2 bits of information. The long format occupies 4-14 symbols and can carry more than 2 bits of information. The purpose of introducing short format PUCCH in NR is to shorten the time delay of hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback. The long format still considers that the long duration can guarantee coverage.

[0108] In NR, considering the flexibility of system configuration, all PUCCHs with more than or equal to 2 symbols can be configured to hop, including intra-slot and inter-slot hopping. The number of symbols in the first hop is, and the remaining symbols are in the second hop.

[0109] PUCCH format 0 1 3 4 all use low peak to average power ratio (low-PAPR) sequences, which can reduce the peak to average ratio of uplink transmission. The low-PAPR sequence is generated by cyclic shift on the basis of a basic sequence, and the basic sequence is divided into two cases according to the length of the sequence.

[0110] 2. Physical uplink shared channel

[0111] The physical uplink shared channel (PUSCH, Physical Uplink Shared Channel) is used to carry data from the transport channel USCH. The so-called sharing means that the same physical channel can be used by multiple users in time-sharing, or the channel has a short duration.

[0112] 3. Control resource set

[0113] The control resource set (Control-Resource Set, CORESET) mainly indicates the number of symbols (time domain) and RB (frequency domain) occupied by the physical downlink control channel, that is, the CORESET indicates the frequency domain resource including the PDCCH. The CORESET contains a plurality of PRBs, the minimum is 6 in the time domain, and the number of symbols is 1-3. Each cell can be configured with multiple CORESETs (0-11), of which COREST0 can be used for scheduling of the remaining minimum system information (Remaining Minimum System Information, RMSI) (which can also be called System Information Block Type 1 (System Information Block Type 1, SIB1).

[0114] 4. Physical downlink control channel

[0115] The physical downlink control channel (Physical Downlink Control Channel, PDCCH) carries scheduling and other control information, including transmission format, resource allocation, uplink scheduling permission, power control, and uplink retransmission information. The PDCCH channel is a set of physical resource particles, which carries uplink and downlink control information. According to the scope, the PDCCH carries information is divided into public control information (common search space) and dedicated control information (dedicated search space).

[0116] 5. Master information block

[0117] Master Information Block (MIB), when the network side device is powered on, the MIB message will be sent first, and then a series of system information block (SIB) messages will be sent. The MIB message carries the most basic information, which is related to the decoding of the physical downlink shared channel. The UE can only decode the MIB first, and then use the parameters in the MIB to continue decoding the data in the physical downlink shared channel, including decoding the system message block information.

[0118] 6. Radio Resource Control State

[0119] RRC State, the terminal device has three RRC states: RRC connected state, RRC idle state and RRC inactive state.

[0120] RRC connected state (or, it can also be referred to as connected state. In this article, "connected state" and "RRC connected state" are the same concept, and the two designations can be interchanged): the terminal device establishes an RRC connection with the network and can perform data transmission.

[0121] RRC idle state (or, it can also be referred to as idle state. In this article, "idle state" and "RRC idle state" are the same concept, and the two designations can be interchanged): the terminal device does not establish an RRC connection with the network, and the base station does not store the context of the terminal device. If the terminal device needs to enter the RRC connected state from the RRC idle state, it needs to initiate an RRC connection establishment process.

[0122] RRC inactive state (or, it can also be referred to as inactive state. In this article, "inactive state", "deactivated state", "inactive state", "RRC inactive state" or "RRC deactivated state" are the same concept, and the several designations can be interchanged): the terminal device previously entered the RRC connected state at the anchor base station, and then the anchor base station released the RRC connection, but the anchor base station saved the context of the terminal device. If the terminal device needs to enter the RRC connected state again from the RRC inactive state, it needs to initiate an RRC connection recovery process (or, RRC connection re-establishment process) at the currently camped base station. Because the terminal device can be in a mobile state, the terminal device's current camped base station can be the same as the terminal device's anchor base station, or it can be different. The RRC recovery process has shorter latency and smaller signaling overhead than the RRC establishment process. However, the base station needs to save the context of the terminal device, which will occupy the storage overhead of the base station.

[0123] 7. System Information Block

[0124] System Information Block (SIB) is the system information broadcast by the base station, divided into multiple types, so that different frequencies can be used for transmission. There are 19 types of SIBs in total, and the scheduling information of SIB is carried by MIB or SB.

[0125] In order to ensure data transmission between the terminal device and the NR base station, the terminal device needs to establish a connection with the NR base station through a random access process, so that the NR base station can identify the terminal device and complete subsequent data transmission. Taking initial access as an example, the NR Legacy terminal device is in idle state, and through receiving the synchronization signal block (SSB) sent by the NR base station, time-frequency synchronization between the terminal device and the NR base station can be achieved, and initial access configuration information of the cell corresponding to the NR base station, i.e. system information block 1 (SIB1) information, can be obtained. In SIB1, resources for the terminal device to initiate random access will be configured, as well as a continuous bandwidth resource including the random access resource. This continuous bandwidth resource is currently defined as the uplink initial bandwidth part (BWP) in the protocol. The uplink initial BWP can be used for the physical uplink shared channel (PUSCH) for transmitting message 3 (Msg3) in the random access process, the physical uplink control channel (PUCCH) for transmitting message A (Msg A) and for transmitting hybrid automatic repeat request (HARQ) feedback in the random access process, wherein the HARQ feedback is the feedback for message 4 (Msg 4) or for message B (Msg B) in the random access process. In addition, the physical random access channel (PRACH) resource in the random access process must also be transmitted in the uplink initial BWP. Further, the terminal device can also ensure the data transmission performance between the terminal device and the base station in the random access process and the RRC connection process through PUCCH frequency hopping and PUSCH frequency hopping, wherein the frequency range of PUCCH frequency hopping and the frequency range of PUSCH frequency hopping also need to be ensured within the uplink initial BWP. Therefore, it is necessary to define the frequency range including the above data transmission resource and frequency hopping resource for the NR terminal device, so as to ensure the establishment of data transmission connection with the base station.

[0126] It should be understood that the form of the uplink initial BWP here can not only be a set of frequency resources to ensure random access data transmission, but also be used for data transmission in other scenarios.

[0127] In addition, even if the terminal device enters the connected state, data transmission based on the uplink initial BWP corresponding to the initial access stage will be completed under some conditions.

[0128] In combination with the above description, for the NR RedCap UE, in order to ensure data transmission with the base station, it is also necessary to consider designing the uplink initial BWP for the RedCap UE.

[0129] Figure 3 An architecture diagram for a random access stage system data transmission. In the prior art, first, in the random access stage, the frequency resource configuration of the uplink initial BWP is included in the SIB1 information, and before receiving the SIB1 information, the data transmission between the terminal device and the base station is as shown in Figure 3 It can be observed that the terminal device does not send uplink information before receiving the SIB1 information, that is, there is no interaction between the cell corresponding to the NR base station, and therefore the NR base station (or network side device) cannot obtain the type of the terminal device, that is, it is not determined whether the terminal device receiving the SIB1 information is a terminal device with a bandwidth capability of 100MHz or a terminal device with a bandwidth capability not greater than 20MHz (such as an NR RedCap terminal device). This will result in the following problems in the prior art:

[0130] (1) The network device configured uplink initial BWP bandwidth exceeds the bandwidth capability of the NR RedCap UE, resulting in the NR RedCap terminal device being unable to access.

[0131] For example, the PRACH resource is included in the uplink initial BWP, and according to the current protocol, the total PRACH resource bandwidth configured by the network device will exceed 20MHz. On the other hand, in the NR system, there is a correspondence between the SSB and the PRACH resource (such as the preamble). The UE can select the corresponding preamble to initiate random access according to the detected SSB and the correspondence between the SSB and the preamble. The network device can determine the SSB beam direction detected by the UE that initiates the preamble through the received preamble. Before establishing a radio resource control (RRC) connection with the UE, the network device sends downlink data to the UE through the SSB beam direction corresponding to the preamble, which can ensure the downlink data transmission performance. However, since the total PRACH resource bandwidth configured by the network device will exceed 20MHz, it will cause the NR RedCap UE to be unable to select the PRACH resource corresponding to the best SSB beam direction, thereby affecting the data transmission performance of the RedCap UE, and even causing the RedCap UE to be unable to access.

[0132] (2) Limiting the bandwidth of the uplink initial BWP corresponding to the NR Legacy UE affects the initial access performance of the NR Legacy UE.

[0133] The network device considers that there may be NR RedCap UEs in the system, and when configuring the uplink initial BWP bandwidth, the uplink initial BWP bandwidth size can be configured to be not greater than the bandwidth capability of the NR RedCap UE, which can ensure the access of the RedCap UE, but this will limit the access performance of the Legacy UE. For example, as described above, the UE can determine the frequency hopping resource range of the uplink transmission channel according to the size of the uplink initial BWP. Limiting the bandwidth of the uplink initial BWP will reduce the frequency hopping resource range of the uplink transmission channel and affect the data transmission performance. For another example, configuring the uplink initial BWP bandwidth according to the NR RedCap UE will also affect the capacity of the legacy UE access. For example, for the NR Legacy UE, the uplink initial BWP can be configured to a maximum of 100MHz, and if the NR RedCap UE and the NR Legacy UE share the uplink initial BWP, the bandwidth of the uplink initial BWP can only be configured to 20MHz. The reduction of the bandwidth of the uplink initial BWP will reduce the capacity of the NR Legacy UE access.

[0134] Figure 4A schematic diagram of resource load of data transmission frequency resource. Wherein, the first type of terminal device can be a low-cost, low-bandwidth terminal device, such as an NR RedCap UE, and the second type of terminal device can be a legacy terminal device (NR Legacy UE, such as an NR eMBB UE). As shown in the figure, due to the bandwidth capability limitation of the first type of terminal device, the data transmission frequency resource for the non-connected state cannot exceed the bandwidth capability of the first type of terminal device in one way, which makes the data transmission between the network device and the first type of terminal device in the non-connected state, such as the initial access stage, only concentrated in the frequency range corresponding to the bandwidth capability of the first type of terminal device. Considering that in the non-connected state, such as the initial access stage, the network device cannot identify each first type of terminal device, it is impossible to configure data transmission frequency resource for each first type of terminal device through the dedicated signaling of the terminal device, which will further lead to the fact that the first type of terminal device aiming to establish an RRC connection with the network device in the non-connected state will be concentrated in a frequency range, such as 20MHz. Considering that in the non-connected state, the 20MHz will include the transmission of the following channels: preamble transmission, Msg3 transmission in the random access process, HARQ-ACK transmission for Msg4, etc., and for the terminal device in the connected state, it will also fall back to the corresponding data transmission frequency resource in the non-connected state to complete the data transmission with the network device under certain conditions. This will lead to an excessive load on the data transmission frequency resource in the non-connected state, especially when considering that the number of first type of terminal devices is relatively large, which will further increase the load on the data transmission frequency resource. There is no above-mentioned problem for the second type of terminal device, because the mandatory bandwidth capability of the second type of terminal device is 100MHz, so the network device can configure a data transmission frequency resource with a larger frequency resource range.

[0135] The difference between the first terminal device and the second terminal device includes at least one of the following:

[0136] 1. Different bandwidth capabilities. For example, the second type of terminal device can support a maximum of 100MHz frequency domain resource on one carrier for simultaneous data transmission with the network device, while the first type of terminal device can support a maximum of 20MHz, 10MHz or 5MHz frequency domain resource on one carrier for simultaneous data transmission with the network device.

[0137] 2. The number of transceiver antennas is different. For example, the minimum supported antenna configuration of the second type of terminal device is 4Tx2Rx, that is, in the minimum antenna configuration, 4 receive antennas are used to receive downlink data, and 2 transmit antennas are used to transmit uplink data; while the maximum supported antenna configuration of the first type of terminal device is lower than 4Tx2Rx, for example, the first type of terminal device UE only supports 2Rx1Tx, or can also support 1Rx1Tx, or can also support 2Rx2Tx.

[0138] 3. The maximum uplink transmit power is different. For example, the maximum uplink transmit power of the second type of terminal device can be 23dBm or 26dBm, while the maximum uplink transmit power of the first type of terminal device can be one value in the range of 4dBm-20dBm.

[0139] 4. The protocol versions corresponding to the first type of terminal device and the second type of terminal device are different. For example, NR Rel-15 and NR Rel-16 terminal devices can be considered as the second type of terminal device, while the first type of terminal device can be considered as the NR Rel-17 terminal device.

[0140] 5. The carrier aggregation (CA) capabilities supported by the first type of terminal device and the second type of terminal device are different. For example, the second type of terminal device can support carrier aggregation, while the first type of terminal device does not support carrier aggregation; for another example, both the first type of terminal device and the second type of terminal device support carrier aggregation, but the maximum number of carrier aggregation simultaneously supported by the second type of terminal device is greater than the maximum number of carrier aggregation simultaneously supported by the first type of terminal device. For example, the second type of terminal device can support aggregation of at most 5 carriers or 32 carriers simultaneously, while the first type of terminal device can support aggregation of at most 2 carriers simultaneously.

[0141] 6. The second type of terminal device supports Frequency Division Duplexing (FDD), while the first type of terminal device supports half-duplex FDD. The processing time capabilities of the first type of terminal device and the second type of terminal device for data are different. For example, the minimum time delay between receiving downlink data and sending feedback on the downlink data by the second type of terminal device is less than the minimum time delay between receiving downlink data and sending feedback on the downlink data by the first type of terminal device. The minimum time delay between sending uplink data and receiving feedback on the uplink data by the second type of terminal device is less than the minimum time delay between sending uplink data and receiving feedback on the uplink data by the first type of terminal device.

[0142] 7、The processing capability of the second type terminal device is different from that of the first type terminal device. The processing capability of the first type terminal device is lower than that of the second type terminal device. For example, the first type terminal device and the second type terminal device have different time capability for processing data. For example, the minimum time delay between the second type terminal device receiving downlink data and sending feedback for the downlink data is less than the minimum time delay between the first type terminal device receiving downlink data and sending feedback for the downlink data. The minimum time delay between the second type terminal device sending uplink data and receiving feedback for the uplink data is less than the minimum time delay between the first type terminal device sending uplink data and receiving feedback for the uplink data. For another example, the maximum transmission block size (TBS) that the first type terminal device can process is less than the maximum TBS that the second type terminal device can process. For another example, the maximum downlink modulation order (such as 64QAM) that the first type terminal device can process is less than the maximum downlink modulation order (such as 256QAM) that the second type terminal device can process, and / or the maximum uplink modulation order (such as 64QAM or 16QAM) that the first type terminal device can process is less than the maximum uplink modulation order (such as 256QAM or 64QAM) that the second type terminal device can process. For another example, the number of hybrid automatic repeat reQuest (HARQ) supported by the first type terminal device is less than the number of HARQ supported by the second type terminal device.

[0143] 8、The transmission rate of the uplink (or downlink) transmission peak of the second type terminal device is different from the corresponding uplink (or downlink) transmission peak rate of the first type terminal device. The corresponding uplink (or downlink) transmission peak rate of the first type terminal device is lower than the transmission rate of the uplink (or downlink) transmission peak of the second type terminal device.

[0144] In the embodiments of the present application, the first type terminal device is taken as an example of an NR RedCap terminal device, and the second type terminal device is taken as an example of an NR Legacy terminal device.

[0145] Figure 5 A system architecture diagram suitable for wireless access in the embodiments of the present application is shown. As shown in the figure, the network device and the terminal device of the present application are connected by an air interface.

[0146] In the present application, the terminal device includes a device that provides voice and / or data connectivity to a user, for example, can include a handheld device with wireless connection function, or a processing device connected to a wireless modem. More specifically, for example, it can be an LTE terminal, a 5G terminal, a UE.

[0147] A network device, including an access network (AN) device, such as a base station (e.g., an access point), can refer to a device in an access network that communicates with wireless terminal devices over the air through one or more cells. Optionally, it can be, for example: an LTE eNB / HeNB / Relay / Femto / Pico, a 5G base station.

[0148] Description of terminal device: In this application, terminal device can also include relay, and all devices that can communicate data with network device can be regarded as terminal device.

[0149] In this application, a cell can be understood as a carrier.

[0150] It should be noted that in this application, although low-capability or low-cost or low-complexity terminal devices are described as examples, the embodiments listed are also applicable to other types of terminal devices, such as NR Rel-17 or later terminal devices. For ease of description, this application describes NR RedCap UE as an example.

[0151] It should be noted that in this application, the data transmission frequency resource, or the maximum frequency resource for PUSCH transmission, the maximum frequency resource for PUCCH transmission, and the maximum frequency resource for NR RedCap UE preamble transmission are all composed of continuous resource blocks (RBs).

[0152] The various embodiments provided by this application will be described in detail below with reference to the accompanying drawings.

[0153] Figure 6 An exemplary flowchart of a method for wireless access suitable for embodiments of this application. The method 600 can include the following steps.

[0154] In the following embodiments, in order to distinguish and not lose generality, the first device represents the network device, and the second device represents the first type of terminal device, such as the NR RedCap UE.

[0155] It should be understood that the first device can also have other forms, for example, the first device and the second device can both be the first type of terminal device, or the first device can also be the second type of terminal device (NR Legacy UE, such as NR eMBB UE), and the second device can be the first type of terminal device. Here, no limitation is made.

[0156] It should be understood that, in the present application, the main difference between the first type of terminal device and the second type of terminal device is that the bandwidth capabilities are different, but in the specific implementation process, the difference between the first type of terminal device and the second type of terminal device is not limited to the difference in bandwidth capability, that is, the difference in bandwidth capability is not a necessary distinguishing feature.

[0157] S601 The first device determines a first frequency resource.

[0158] For example, the first device can determine the first frequency resource, wherein the first frequency resource includes a frequency resource for transmitting a physical uplink control channel (PUCCH), the first frequency resource is one of M frequency resources for transmitting a PUCCH, the M frequency resources for transmitting a PUCCH are M frequency resources of N second frequency resources, the second frequency resources are used for transmitting uplink data of the first type of terminal device, wherein M is less than N, and M and N are positive integers.

[0159] It should be understood that, in the embodiments of the present application, the second frequency resource can be used for transmitting random access uplink data of the first type of terminal device, and can also be used for random access uplink data of the second type of terminal device.

[0160] It should be understood that, in the embodiments of the present application, when the first device determines the first frequency resource, although the first frequency resource is one of M frequency resources for transmitting a PUCCH, and the M frequency resources for transmitting a PUCCH are M frequency resources of N second frequency resources, the first device can directly determine the frequency resource for transmitting a PUCCH without determining the second frequency resource.

[0161] It should be noted that the second frequency resource is used for transmitting uplink data, and preferably, the uplink data here can include uplink data in a random access process, such as a random access preamble, Msg A, Msg 3, and HARQ-ACK transmission for random access Msg 2 or Msg 4, wherein the HARQ-ACK transmission is carried in a PUCCH. In a possible implementation manner, the second frequency resource can also be used for uplink data transmitted by the first type of terminal device in an RRC connected state.

[0162] Taking random access as an example, defining N second frequency resources for uplink data transmission of the first type of terminal device can achieve service load balancing, especially for large connection first type of terminal device.

[0163] In addition, defining M second frequency resources including PUCCH transmission in N second frequency resources (where M is less than N) can reduce the impact of PUCCH transmission, especially PUCCH frequency hopping transmission, on the performance of PUSCH transmission of other terminal devices in the system, for example, on the performance of PUSCH transmission of legacy UEs or wideband UEs (for example, channel bandwidth capability of 100MHz) in the system; on the other hand, considering that PUCCH can support multi-user multiplexing transmission, it is not necessary to include PUCCH transmission in each second frequency resource, so that the overhead of PUCCH can be reduced while ensuring the performance of multi-user HARQ-ACK transmission.

[0164] In a possible implementation, only one of the N second frequency resources includes the frequency resource for PUCCH transmission, which can further reduce the transmission overhead of the PUCCH. Further in a possible implementation, when only one of the N second frequency resources includes the frequency resource for PUCCH transmission, the first frequency resource is the frequency resource with the highest frequency or the lowest frequency among the N second frequency resources. Taking N = 3 as an example, assuming that one of the three second frequency resources includes a frequency resource range corresponding to a common resource block (CRB) with a CRB index of p1 and a CRB with a CRB index of p2, another one of the second frequency resources includes a frequency resource range corresponding to a CRB with a CRB index of p3 and a CRB with a CRB index of p4, and the other one of the second frequency resources includes a frequency resource range corresponding to a CRB with a CRB index of p5 and a CRB with a CRB index of p6, where p1 < p2 < p3 < p4 < p5 < p6, the frequency resource for PUCCH transmission or the first frequency resource can correspond to a frequency resource with a frequency start point of the CRB with the CRB index of p1 and a frequency end point of the CRB with the CRB index of p2, or the frequency resource for PUCCH transmission or the first frequency resource can also correspond to a frequency resource with a frequency start point of the CRB with the CRB index of p5 and a frequency end point of the CRB with the CRB index of p6. Here, the CRB is a resource block determined relative to a system carrier point A, which can correspond to a lowest frequency subcarrier included in a lowest frequency resource block included in the system carrier, or a lowest frequency domain resource unit included in the system carrier bandwidth, where the lowest frequency domain resource unit includes a lowest frequency subcarrier corresponding in the system carrier bandwidth. Alternatively, in this application, the highest frequency or the lowest frequency can also be represented by the frequency corresponding to the subcarrier included in the second frequency resource, among the N second frequency resources, the second frequency resource including the lowest frequency subcarrier can be understood as the frequency resource with the lowest frequency among the N second frequency resources, and the second frequency resource including the highest frequency subcarrier can be understood as the frequency resource with the highest frequency among the N second frequency resources. Alternatively, in this application, the highest frequency or the lowest frequency can also be determined by the absolute frequency corresponding to the frequency resource included in the N second frequency resources. Alternatively, other manners can also be used, which are not limited specifically.Since the PUCCH generally adopts frequency hopping in order to ensure the performance of the PUCCH transmission, limiting the first frequency resource including the PUCCH transmission to the frequency resource with the highest frequency or the frequency resource with the lowest frequency among the N second frequency resources can reduce the impact on the PUSCH transmission performance of other terminal devices, such as the second-type terminal device, the terminal device with a large bandwidth capability (for example, 100 MHz), the legacy terminal device, and the like.

[0165] In a possible implementation, the first frequency resource has the following characteristics: the first frequency resource is the frequency resource with the highest frequency or the frequency resource with the lowest frequency included in a specific frequency resource, for example, the first frequency resource is a continuous frequency resource in the specific frequency resource, and includes the frequency domain resource unit with the highest frequency or the frequency domain resource unit with the lowest frequency in the specific frequency resource. The specific frequency resource can be the system uplink carrier corresponding to the first-type terminal device or the system uplink carrier corresponding to the second-type terminal device, and the system uplink carrier corresponding to the first-type terminal device or the system uplink carrier corresponding to the second-type terminal device can be the same or different. Alternatively, the specific frequency resource can also be the uplink initial BWP corresponding to the second-type terminal device, or the specific frequency resource can also be the uplink channel transmission bandwidth corresponding to the first-type terminal device or the uplink channel transmission bandwidth corresponding to the second-type terminal device. Since the PUCCH generally adopts frequency hopping in order to ensure the performance of the PUCCH transmission, configuring the first frequency resource including the PUCCH transmission on one side of the frequency resources of the specific frequency resource can reduce the impact on the data transmission rate of other terminal devices in the system, such as the second-type terminal device.

[0166] It should be understood that the second frequency resource herein can not only be the frequency resource for ensuring random access data, but also be the frequency resource for transmitting other uplink data. In a TDD system, the second frequency resource can also be used for transmitting downlink data.

[0167] The first device can inform the second device of the first frequency resource in a manner of broadcast information notification or a manner of RRC dedicated signaling, which is not limited herein. Alternatively, the first device can also indicate the first frequency resource through physical layer signaling.

[0168] The first device sends the first indication information to the second device, S602.

[0169] For example, the first device sends the first indication information, and the first indication information is used to indicate the configuration information of the first frequency resource and / or the information of the resource index used for transmitting the PUCCH.

[0170] Specifically, one implementation is that the first device, when configuring N second frequency resources, implements the first frequency resource including the PUCCH transmission through the second frequency resource identification. For example, the first device informs the N second frequency resources through the broadcast information, but only 1 is the frequency resource including the PUCCH transmission. When the first device configures the N second frequency resources, the second frequency resource corresponding identification information can be configured at the same time, which is used to indicate whether the second frequency resource includes the PUCCH resource. One implementation is that the first device can configure the second frequency resource index including the PUCCH resource to indicate which second frequency resource includes the PUCCH resource. For example, the first device configures 4 second frequency resources, and the second frequency resource indexes corresponding to the 4 second frequency resources are 0, 1, 2 and 3 respectively. In this implementation, the first device configures the second frequency resource index including the PUCCH resource as any one of the second frequency resource indexes 0-3. Or the first device can directly configure whether the N second frequency resources include the PUCCH resource to indicate the second frequency resource including the PUCCH resource. For example, the first device configures 4 second frequency resources, and the frequency resource indexes are 0-3 respectively. At the same time, the first device only configures the PUCCH resource for the second frequency resource with the frequency resource index 0, and does not configure the PUCCH resource for other second frequency resources. Through the identification of the frequency resource including the PUCCH transmission in the resource configuration, the first frequency resource can be determined.

[0171] In one possible implementation, the first device can inform the second device of the configuration information of the first frequency resource and / or the information of the resource index for the PUCCH transmission through the broadcast information.

[0172] In the embodiment of the present application, the configuration information of the first frequency resource includes at least one of the following: the frequency resource position of the first frequency resource (including the bandwidth size and the frequency start position), the configuration information of the PUCCH transmission in the first frequency resource, the configuration information of the PUCCH transmission including at least one of the following: the PUCCH transmission format, the symbol number corresponding to the PUCCH transmission, the frequency resource of the PUCCH transmission, and the code resource of the PUCCH transmission.

[0173] In an implementation, the first device can directly notify the configuration information of the first frequency resource, which can be notified through system broadcast information, RRC dedicated signaling or physical layer signaling, or other manners, which are not limited. In another implementation, the first device can configure N second frequency resources, and indicate the identification information of the second frequency resource corresponding to the first frequency resource to configure the first frequency resource. For example, the first device configures 4 second frequency resources, and the second frequency resource with index 0 is identified as the frequency resource including the PUCCH resource (the implementation is the same as the above embodiment), and the second frequency resource identified as including the PUCCH resource can be determined as the first frequency resource.

[0174] In another implementation, the first device can also notify the resource index information for transmitting the PUCCH, which can be the frequency resource information, such as resource block information, applied to the PUCCH transmission.

[0175] Specifically, for example, the first device can indicate the configuration information of the first frequency resource and / or the resource index information for transmitting the PUCCH to the second device through the Location And Bandwidth for RedCap UE included in the SIB1. It should be understood that the broadcast information here can be the information carried by the physical broadcast channel (PBCH), such as the information included in the MIB, or the information included in the control information scheduling the transmission of the system information block SIB or the information included in the SIB information, wherein the control information scheduling the transmission of the SIB can be carried in the PDCCH, and the SIB information can be carried in the PDSCH.

[0176] In a possible implementation, the first device can indicate the configuration information of the first frequency resource and / or the resource index information for transmitting the PUCCH to the second device through RRC dedicated signaling.

[0177] Specifically, the first device can configure the information of the target frequency resource and / or the resource index information for transmitting the PUCCH through RRC dedicated signaling when the second device falls back to the RRC inactive state, which can be used for the second device to perform data transmission with the first device through the first frequency resource in the non-connected state.

[0178] In a possible implementation, the first device can also indicate the configuration information of the first frequency resource and / or the resource index information for transmitting the PUCCH through physical layer signaling.

[0179] Preferably, the first device can send the configuration information of the first frequency resource to the second device through the Location And Bandwidth for RedCap UE included in the SIB1, or send the configuration information of the first frequency resource to the second device through other information included in the SIB1. Alternatively, the first device can send the configuration information of the first frequency resource or the resource index information of the PUCCH to the second device through the control information included in the Msg2 or the Msg4 in the random access procedure.

[0180] The second device determines the first frequency resource, S603.

[0181] For example, the second device can determine the first frequency resource according to the first indication information sent by the first device.

[0182] In a possible implementation, when the indication information is used to indicate the resource index of the PUCCH, the second device needs to determine the resource block of the PUCCH according to the resource index of the PUCCH, and determine the first frequency resource according to the resource block of the PUCCH, wherein the first frequency resource includes the resource block of the PUCCH. Preferably, the first frequency resource includes at least 2 first frequency resources with the highest frequency or the lowest frequency.

[0183] Figure 7 For a schematic diagram of a frequency resource for transmitting a PUCCH suitable for the embodiments of the present application, as shown in the figure, in the present embodiment, there are 2 second frequency resources, only one second frequency resource includes PUCCH transmission (corresponding to the second frequency resource #1 in the figure), and the second frequency resource #2 does not include the frequency resource for PUCCH transmission. It should be understood that within the frequency resource including the PUCCH transmission, in addition to the frequency resource for PUCCH transmission, the frequency resource for PUSCH transmission can also be included. In a possible implementation, among the 2 second frequency resources, one second frequency resource (i.e. the second frequency resource #1) can correspond to the uplink initial BWP of the first type terminal device, for example, the RedCap terminal device.

[0184] Only one of the at least two second frequency resources includes a PUCCH resource can reduce the control channel overhead. Considering that the data carried on the PUCCH can be multiplexed by frequency division multiplexing (FDM) and code division multiplexing (CDM) in addition to multi-user multiplexing, in addition, in the non-connected state, the data transmission carried on the PUCCH is mainly the HARQ-ACK feedback of the downlink data, and in view of the above two points, the PUCCH transmission resource has smaller resource overhead than the PUSCH transmission resource, so it is not necessary to include PUCCH resource in each first frequency resource, so as to ensure a certain peak rate of uplink data transmission for the first frequency resource that does not include PUCCH. In addition, if only one second frequency resource includes PUCCH transmission, the data transmission performance of the NR Legacy UE will be less affected. This is because the at least two second frequency resources are FDM in frequency, but there may be some frequency resource overlap. If PUCCH resources are included on each second frequency resource, considering that the PUCCH resource is generally small in bandwidth and is respectively arranged on both sides of the second frequency resource in order to ensure performance as shown in the figure, it will result in multiple narrowband and discrete PUCCH resources in a carrier bandwidth, which in turn affects the continuous resource size of the uplink data transmission of the NR Legacy UE and the allocation of the resource block group (RBG). Through the present embodiment, even for the NR RedCap UE, there are at least two second frequency resources, and only one second frequency resource includes a PUCCH resource, which not only ensures the data transmission performance of the NR RedCap UE, but also reduces the impact on the data transmission performance of the NR Legacy UE.

[0185] It should be understood that the data transmission frequency resource of the PUCCH transmission can correspond to the uplink initial BWP of the RedCap UE.

[0186] For example, the second device can determine the second frequency resource according to the indication information of the first device, and further determine the first frequency resource from the second frequency resource.

[0187] In a possible implementation manner, the second device can determine the second frequency resource according to the received indication information sent by the first device.

[0188] For example, the number of second frequency resources can be associated with the transmission bandwidth of the downlink system information of the second type terminal device. The larger the bandwidth, the larger the number N.

[0189] For example, the number of the second frequency resources can be associated with a frequency resource used for transmitting random access uplink data of the second type terminal device.

[0190] For example, the number of the second frequency resources can be associated with a carrier bandwidth informed by the first device or a frequency band where the system carrier is located.

[0191] For example, the second device can determine the number N of the second frequency resources according to one or more of a bandwidth of the system carrier, a frequency band where the system carrier is located, a frequency resource used for transmitting random access uplink data of the second type terminal device, a transmission bandwidth used for transmitting downlink system information of the second type terminal device. In this application, no limitation is made. The transmission bandwidth used for transmitting downlink system information of the second type terminal device can be a transmission bandwidth of a downlink initial BWP corresponding to the second type terminal device, for example, a frequency domain resource corresponding to CORESET#0 indicated by pdcch-ConfigSIB1 control field in MIB.

[0192] For example, the second device can determine the second frequency resources according to the number of the second frequency resources and a frequency resource used for transmitting random access uplink data of the second type terminal device, for example, determine a frequency location of each second frequency resource.

[0193] For example, the second device can determine a location of each second frequency resource according to the number of the second frequency resources and a number of random access preamble RACH resources.

[0194] S604 The second device transmits PUCCH to the first device in the first frequency resource.

[0195] For example, after the second device determines the first frequency resource including a frequency resource used for transmitting PUCCH, the second device can transmit PUCCH through the first frequency resource, and the first device receives data carried by the PUCCH from the second device in the first frequency resource.

[0196] It should be understood that the above embodiment takes one terminal device in the first type terminal device, i.e., the second device, as an example, however, the first frequency resource can be a frequency resource suitable for the first type terminal device.

[0197] Figure 8 Another exemplary flowchart of a method suitable for the uplink data transmission method of the embodiments of the present application. The method 800 can include the following steps.

[0198] In the following embodiments, the first device represents a network device and the second device represents a first type terminal device (e.g., NR RedCap UE) for distinction and without loss of generality.

[0199] It should be understood that the first device can also have other forms, for example, the first device and the second device can both be the first type of terminal device, or the first device can also be the second type of terminal device (NR Legacy UE, such as NR eMBB UE), and the second device can be the first type of terminal device. Here, no limitation is made.

[0200] It should be understood that in this application, the main difference between the first type of terminal device and the second type of terminal device is the difference in bandwidth capability, but in the specific implementation process, the difference between the first type of terminal device and the second type of terminal device is not limited to the difference in bandwidth capability, that is, the difference in bandwidth capability is not a necessary distinguishing feature.

[0201] S801 The first device determines a third frequency resource.

[0202] For example, the first device can determine the third frequency resource, wherein the third frequency resource is or is understood to include a frequency resource for transmitting a PUCCH, and the number of the third frequency resource is 1. The frequency resource range of the third frequency resource is different from the frequency resource range of a fourth frequency resource, and the fourth frequency resource includes a frequency resource for transmitting a PUSCH. Alternatively, it can also be understood that the maximum frequency resource range for transmitting the PUCCH is different from the maximum frequency resource range for transmitting the PUSCH.

[0203] In a possible implementation, the frequency resource range of the third frequency resource is smaller than the frequency resource range of the fourth frequency resource.

[0204] In the prior art, when the terminal device and the network device perform data transmission, the frequency resource (which can correspond to the third frequency resource) used for transmitting the PUCCH and the frequency resource (which can correspond to the fourth frequency resource) used for transmitting the PUSCH can be the same frequency resource. That is, if the frequency resource used for transmitting the PUCCH is also included in the frequency resource used for transmitting the PUSCH, the maximum frequency resource range used for transmitting the PUCCH and the frequency resource range used for transmitting the PUSCH are the same. For example, in the prior art, at any time, the terminal device performs data transmission with the network device through one activated BWP, and the frequency resource range of the PUSCH transmission resource in the BWP can be the frequency resource range composed of the lowest frequency RB to the highest frequency RB included in the BWP. Although the frequency resource range of the PUCCH transmission resource in the BWP can be configured, the configurable frequency resource range can also be the frequency resource range composed of the lowest frequency RB to the highest frequency RB included in the BWP. In addition, generally, in order to ensure the performance of the PUCCH transmission, the terminal device will perform transmission through PUCCH frequency hopping in a time slot, so that the PUCCH transmission obtains frequency diversity gain. For example, the specific frequency resource (represented by PRB) of the PUCCH transmission in a time slot can be determined in the following manner: in a time slot, the PRB index corresponding to the frequency resource of the first hop PUCCH is the PRB index corresponding to the frequency resource of the second hop PUCCH is wherein C and PUCCH resource index and are related to the total number of initial cyclic indexes allocated to the PUCCH resource, is the PRB or RB corresponding to the PRB index allocated to the PUCCH transmission by the network device for the terminal device, is the BWP frequency domain resource size or can also be understood as the BWP frequency resource range, wherein the BWP frequency resource range or the frequency resource size can be represented by the number of PRBs or RBs included in the BWP. Based on the above formula, it can be understood that the maximum frequency resource range used for transmitting the PUCCH is the BWP frequency resource size or the BWP frequency resource range (for example, when and C=0). Considering that the BWP can also include PUSCH transmission, the network device can schedule the PUCCH frequency resource distribution of the terminal device in the whole BWP. For a terminal device with unlimited bandwidth, for example, an NR Legacy terminal device (which can correspond to the second type of terminal device in the embodiments of the present application), since its bandwidth can reach 100MHz, the maximum frequency resource range for PUCCH transmission and the maximum frequency resource range for PUSCH transmission can be both 100MHz, which can achieve PUCCH frequency hopping gain and ensure PUSCH transmission performance. However, for a terminal device with limited bandwidth or low capability (corresponding to the second device or the first type of terminal device in the embodiments of the present application), since its bandwidth capability is limited, for example, only 20MHz, in order to ensure the performance of PUCCH frequency hopping transmission, the third frequency resource range including PUCCH transmission can only be the channel bandwidth of the terminal device, for example, 20MHz, so that the existing technology will cause the maximum frequency resource range of PUSCH transmission to also be only 20MHz, which will limit the frequency selection scheduling gain of PUSCH transmission. Generally, the larger the maximum frequency resource range used for transmitting PUSCH, the greater the flexibility of scheduling PUSCH transmission, and the greater the frequency selection scheduling gain. Based on this, in the embodiments of the present application, for the first type of terminal device, the frequency resource range of the frequency resource used for transmitting the PUCCH of the terminal device, that is, the third frequency resource, can be different from the frequency resource range of the frequency resource used for transmitting the PUSCH of the terminal device, that is, the fourth frequency resource. For the first type of terminal device, by decoupling the third frequency resource and the fourth frequency resource, the PUCCH frequency hopping can be ensured, and the frequency selection scheduling gain of PUSCH transmission can also be ensured, and then the PUCCH transmission and the PUSCH transmission can be optimized respectively, and the data transmission performance of the first type of terminal device can be improved.

[0205] In a possible implementation, the frequency resource range of the third frequency resource is smaller than the frequency resource range of the fourth frequency resource, which helps to improve the frequency selection scheduling gain of PUSCH.

[0206] In a possible implementation, the frequency resource range of the third frequency resource is not greater than the bandwidth capability of the first type of terminal device, for example, the bandwidth capability of the first type of terminal device is 20 MHz, and the frequency resource range of the third frequency resource is 20 MHz. In this way, the PUCCH frequency hopping gain can be ensured, and the number of symbols of the PUCCH transmission can be unaffected. Conversely, if the frequency resource range of the third frequency resource is greater than the bandwidth capability of the first type of terminal device, the first type of terminal device needs to consider the radio frequency (RF) retuning time between the first hop PUCCH and the second hop PUCCH for PUCCH transmission. The RF retuning time generally corresponds to several orthogonal frequency division multiplexing (OFDM) symbols, that is, the first type of terminal device cannot perform data transmission with the network device (corresponding to the first device in the embodiment of the present application) in the RF retuning time. This will result in a decrease in the number of symbols for PUCCH transmission in one time slot, and further affect the PUCCH transmission performance.

[0207] Figure 9 An example of the frequency resource range suitable for the embodiment of the present application is shown in the figure. As shown in the figure, the maximum frequency resource range for PUSCH transmission of the first type of terminal device is different from the maximum frequency resource range for PUCCH transmission, for example, the maximum frequency resource range for PUSCH transmission can be greater than the maximum frequency resource range for PUCCH transmission. In the maximum frequency resource range for PUCCH transmission, other resources not allocated to PUCCH transmission can be used for PUSCH transmission. It should be noted that the maximum frequency resource range for PUSCH transmission means that the PUSCH transmission resource scheduled by the network device to the first type of terminal device can be distributed on any one or more frequency domain resource units such as RBs included in the maximum frequency resource range. In addition, Figure 9 In the maximum frequency resource range for PUCCH transmission, the frequency resource for PUCCH transmission is only an example of implementation, and the PUCCH transmission frequency resource between the first type of terminal device and the network device can also be distributed on other frequency domain resource units such as RBs included in the maximum frequency resource range for PUCCH transmission.

[0208] Figure 10This is another schematic diagram illustrating the frequency resource range applicable to embodiments of this application. As shown in the figure, it should be noted that the maximum frequency resource used for PUSCH transmission mentioned here can refer to the resource range between the minimum frequency position that can be occupied for PUSCH transmission and the maximum frequency position that can be occupied.

[0209] In the embodiments of this application, the maximum frequency resource range used for PUSCH transmission may overlap with the maximum frequency resource range used for PUCCH transmission, or the maximum frequency resource range used for PUSCH transmission may include the maximum frequency range used for PUCCH transmission, or the maximum frequency resource range used for PUSCH transmission and the maximum frequency resource range used for PUCCH transmission may not overlap, for example, they may be distributed in frequency division multiplexing (FDM).

[0210] For example, the frequency resources in this application embodiment can correspond to BWPs. For instance, the third frequency resource corresponds to the third BWP including PUCCH transmission, and the fourth frequency resource corresponds to the fourth BWP including PUSCH transmission. When the first type of terminal device determines the PUCCH transmission resource using the above formula, the second hop PUCCH transmission resource corresponds to... In This corresponds to the size of the third BWP (for example, the size of the third BWP can be the number of frequency domain resource units included in the third BWP). When the first type of terminal device determines the PUSCH transmission resources, it determines the location of the PUSCH transmission resources based on the fourth BWP. Furthermore, if the first device enables PUSCH frequency hopping transmission for the first type of terminal device, the first type of terminal device determines the frequency resources corresponding to the PUSCH frequency hopping transmission based on the size of the fourth BWP (for example, the size of the fourth BWP can be the number of frequency domain resource units included in the fourth BWP).

[0211] It should be noted that, in this embodiment, the maximum frequency resource range for PUCCH transmission does not mean that all frequency resources (including the frequency resources for PUCCH transmission, such as the third frequency resource) are used for PUCCH transmission. Instead, it refers to the frequency resource range corresponding to the lowest and highest frequency RBs for PUCCH transmission among all possible frequency resources for PUCCH transmission (such as the third frequency resource). Taking BWP as an example, combined with the above formula, it can be found that the frequency resource range corresponding to the lowest and highest frequency RBs for PUCCH transmission among all possible frequency resources for PUCCH transmission is the frequency resource range corresponding to BWP including PUCCH transmission.

[0212] It should be noted that, in the embodiments of the present application, the maximum frequency resource range for transmitting the PUSCH does not mean that all the frequency resources in the frequency resource range (for example, the fourth frequency resource) including the PUSCH transmission are used for transmitting the PUSCH, but means that, in all the frequency resources that can be used for the PUSCH transmission, the frequency resource range corresponding to the RB with the lowest frequency and the RB with the highest frequency used for the PUSCH transmission is regarded as the maximum frequency resource range for transmitting the PUSCH. For example, in the fourth frequency resource range, at a certain time, the PUSCH transmission can include the RB with the lowest frequency included in the fourth frequency resource range, and at another time, the PUSCH transmission can include the RB with the highest frequency included in the fourth frequency resource range, that is, the PUSCH transmission can be flexibly distributed in the fourth frequency resource range including the PUSCH transmission, and the maximum frequency resource range for transmitting the PUSCH is the frequency resource range corresponding to the fourth frequency resource.

[0213] It should be noted that, in the embodiments of the present application, the maximum frequency resource range corresponding to the PUSCH (that is, the fourth frequency resource or the fourth frequency resource range) can be any one of the frequency range of the system uplink carrier notified by the first device, or the frequency range of the uplink channel bandwidth configured by the first device for the second device, or the frequency range of the uplink initial BWP bandwidth configured by the first device for the second type terminal device, or it can also be understood that the fourth frequency resource can be any one of the system uplink carrier notified by the first device, or the uplink channel corresponding to the second device (configured through SIB1 or RRC dedicated signaling), or the uplink initial BWP corresponding to the second type terminal device. The second type terminal device is a terminal device different from the first type terminal device in capability, for example, a terminal device different in bandwidth capability. Since the second device can determine to access the first device, the system uplink carrier bandwidth information transmitted by the first device through broadcast information can be received by the second device, and the uplink initial BWP bandwidth configured by the first device for the second type terminal device can also be received (for example, the uplink initial BWP corresponding to the second type terminal device is determined by receiving SIB1).

[0214] It should be understood that in some embodiments, when the first device can directly determine the frequency resource for transmitting the PUCCH, the step is an optional step, i.e., the first device can directly determine the frequency resource for transmitting the PUCCH without determining the third frequency resource, and further, determine the frequency resource range of the frequency resource for transmitting the PUCCH, which is different from the frequency resource range of the fourth frequency resource, the fourth frequency resource including the frequency resource for transmitting the physical uplink shared channel (PUSCH).

[0215] The first device sends the indication information to the second device, according to S802.

[0216] The first device sends the indication information to the second device, wherein the indication information includes the second indication information and / or the third indication information.

[0217] For example, when the first device determines the frequency resource for transmitting the PUCCH, the first device sends the second indication information, which is used to indicate the frequency resource of the PUCCH.

[0218] For example, when the first device determines the third frequency resource, the first device sends the second indication information, which is used to indicate the third frequency resource, i.e., the frequency resource for transmitting the PUCCH.

[0219] In a possible implementation, taking the BWP corresponding to the third frequency resource as an example, the second indication information can be configuration information corresponding to the BWP. Optionally, the second indication information is used to indicate the third frequency resource, and the second indication information can be indicated at least one of the following: the frequency resource position of the third frequency resource, the frequency resource size of the third frequency resource, and the PUCCH transmission configuration information included in the third frequency resource.

[0220] The first device sends the third indication information, which is used to indicate the fourth frequency resource, i.e., the frequency resource for transmitting the PUSCH.

[0221] In a possible implementation, taking the BWP corresponding to the fourth frequency resource as an example, the third indication information can be configuration information corresponding to the BWP. Optionally, the third indication information is used to indicate the fourth frequency resource, and the third indication information can be indicated at least one of the following: the frequency resource position of the fourth frequency resource, the frequency resource size of the fourth frequency resource, and the PUSCH transmission configuration information included in the fourth frequency resource.

[0222] It can be understood that, by indicating the third frequency resource and the fourth frequency resource through the second indication information and the third indication information respectively, decoupling configuration of the maximum frequency resource range including the PUCCH transmission and the maximum frequency resource range including the PUSCH transmission can be implemented, so that optimization design for the PUCCH transmission and the PUSCH transmission can be respectively implemented, for example, considering the influence of the bandwidth capability of the first type terminal device on the PUCCH frequency hopping transmission, the maximum frequency resource range including the PUCCH transmission is not greater than the bandwidth capability of the first type terminal device. On the other hand, the maximum frequency resource range configured differently from the third frequency resource range and used for the PUSCH transmission can ensure flexible scheduling of the PUSCH, and the influence of the bandwidth capability of the first type terminal device on the PUSCH transmission performance only needs to ensure that the PUCCH transmission resource scheduled each time does not exceed the bandwidth capability of the first type terminal device, but the frequency resource position of the scheduled PUSCH can be flexibly scheduled in the fourth frequency resource range different from the third frequency resource, thereby ensuring the PUCCH frequency selection scheduling gain.

[0223] It can be understood that, in the connected state, the PUCCH transmission is mainly for HARQ-ACK feedback of the Message 4 or the Message B, and therefore the maximum frequency resource range used for the PUCCH transmission (that is, the third frequency resource or the resource range of the third frequency resource) can be transmitted through the Message 4 or the Message B in the random access process, and specifically can be carried by the PDCCH scheduling the Message 4 or the Message B, or can be carried by the PDSCH including the Message 4 or the Message B.

[0224] In a possible implementation, the first device can send the indication information used for indicating the third frequency resource to the second device in one or both of the Message 4 information and the Message B information.

[0225] In a possible implementation, the first device can indicate the third frequency resource to the second device through a broadcast information notification manner. For brevity, the specific broadcast information notification manner is not described here again, and can be referred to the description in S602.

[0226] In a possible implementation, the first device can indicate the first maximum frequency resource range to the second device through RRC dedicated signaling. For brevity, the specific RRC dedicated signaling is not described here again, and can be referred to the description in S602.

[0227] In a possible implementation, the second information can directly indicate the fourth frequency resource.

[0228] In a possible implementation, the second information does not directly indicate the fourth frequency resource, but can indicate a PUSCH scheduling resource, which can be associated with the fourth frequency resource.

[0229] It should be noted that in the embodiments of the present application, the first information and the second information can be carried in system broadcast signaling, RRC dedicated signaling, physical layer control signaling or medium access control (MAC) signaling, and the notification manners of the first information and the second information can be the same or different.

[0230] In the embodiments of the present application, the first device can configure the maximum frequency resource range of the PUCCH transmission (or can be understood as the first device configuring the third frequency resource), for example, configuring the third frequency resource through the second indication information, and the maximum frequency resource range for the PUSCH transmission can not be additionally defined, but directly implemented through scheduling the PUSCH transmission, that is, the maximum frequency resource range for the PUSCH transmission can be implicitly determined through the position of the scheduled PUSCH transmission. The advantage of such implementation is that the PUSCH transmission can be implemented through data scheduling, that is, even if the bandwidth capability of the second device is limited, as long as the bandwidth of the scheduled PUSCH transmission is not greater than the bandwidth capability of the second device each time data is scheduled, and the frequency hopping of the PUSCH can also be implemented through scheduling. However, the PUCCH transmission is different, because considering the multi-user multiplexing, the PUCCH transmission cannot be dynamically scheduled like the PUSCH transmission, and a frequency resource range needs to be considered to support the frequency hopping of the PUCCH transmission. Based on this, the first device can only configure the maximum frequency range of the PUCCH transmission, which can guarantee the data transmission performance of the second device and does not increase the overhead of the indication of the maximum frequency resource range of the data transmission.

[0231] The second device determines the third frequency resource, S803.

[0232] For example, the second device can directly determine the frequency resource for transmitting the PUCCH. The frequency resource for transmitting the PUCCH is included in the third frequency resource, the frequency resource range of the third frequency resource is different from the frequency resource range of the fourth frequency resource, and the fourth frequency resource includes the frequency resource for transmitting the physical uplink shared channel (PUSCH). Optionally, the frequency resource range of the third frequency resource is smaller than the frequency resource range of the fourth frequency resource.

[0233] For example, the second device can determine the third frequency resource. When the second device determines the third frequency resource, the second device can determine the third frequency resource according to the configuration information sent by the first device. For example, the first device can configure the maximum frequency resource range of the PUCCH transmission (or can be understood as the first device configures the third frequency resource), for example, configures the third frequency resource through the second indication information, while the maximum frequency resource range for the PUSCH transmission can not be additionally defined, but directly implemented through scheduling the PUSCH transmission, that is, the maximum frequency resource range for the PUSCH transmission can be implicitly determined through the position of the scheduled PUSCH transmission. The advantage of such implementation is that the PUSCH transmission can be implemented through data scheduling, that is, even if the bandwidth capability of the second device is limited, as long as the bandwidth of the scheduled PUSCH transmission is not greater than the bandwidth capability of the second device each time data is scheduled, and the frequency hopping of the PUSCH can also be implemented through scheduling. However, the PUCCH transmission is different, because considering the multi-user multiplexing, the PUCCH transmission cannot be dynamically scheduled like the PUSCH transmission, and a frequency resource range needs to be considered to support the frequency hopping of the PUCCH transmission. Based on this, the second device can determine the PUCCH transmission frequency resource range according to the maximum frequency range of the PUCCH transmission configured by the first device, and determine the frequency resource range corresponding to the fourth frequency resource according to the association relationship between the scheduled PUSCH transmission resource and the maximum frequency resource range for the PUSCH transmission, so as to guarantee the data transmission performance of the second device and not increase the overhead of the maximum frequency resource range indication of the data transmission.

[0234] For example, the second device can also directly determine the frequency resource for transmitting the PUCCH according to the second indication information from the first device.

[0235] In a possible implementation, the maximum frequency resource range for the PUCCH transmission (that is, the third frequency resource) can be defined as the uplink initial BWP corresponding to the second device.

[0236] In a possible implementation, the transmission range of the maximum frequency resource corresponding to the random access preamble resource is greater than the third frequency resource or the frequency resource range of the third frequency resource.

[0237] The maximum frequency resource range corresponding to the random access preamble resource sent by the second device can be different from the maximum frequency resource range for PUSCH transmission (i.e., the frequency resource range corresponding to the fourth frequency resource) and the maximum frequency resource range for PUCCH transmission (i.e., the frequency resource range corresponding to the third frequency resource). In the current NR system, the transmission bandwidth corresponding to each random access preamble resource sequence does not exceed 20 MHz, that is, the second device can directly use the existing random access preamble resource to implement initial access. Although considering all frequency division multiplexed RACH occasions (FDMed RACH occasion, FDMed RO) frequency resources, the frequency resource range will exceed the transmission bandwidth of the second device, but in terms of each random access preamble resource transmission, the transmission bandwidth is within the bandwidth capability range of the second device. In addition, for PUSCH transmission, as described above, a larger frequency resource range can be realized through scheduling, and it is only necessary to ensure that the bandwidth of each PUSCH transmission does not exceed the bandwidth capability of the second device. However, for PUCCH, the definition of the frequency resource range needs to be considered, and therefore, the configuration of the maximum frequency resource range corresponding to each channel can be considered independently to ensure the data transmission performance of each channel.

[0238] In a possible implementation, the second device can receive fourth indication information, and the fourth indication information is used to indicate the maximum frequency resource range corresponding to the random access preamble resource for the first type of terminal device. For example, if the fourth indication information indicates the FDMed RO, the frequency resource range corresponding to the FDMed RO can be the maximum frequency resource range corresponding to the random access preamble resource for the first type of terminal device. The random access preamble resource for the first type of terminal device can also be used for random access of the second type of terminal device, and in this case, the fourth indication information can also indicate the maximum frequency resource range corresponding to the random access preamble resource for the second type of terminal device. That is, the maximum frequency resource range corresponding to the random access preamble resource of the first type of terminal device can be the same as the maximum frequency resource range corresponding to the random access preamble resource of the second type of terminal device.

[0239] In a possible implementation, in the embodiment of the present application, the maximum frequency resource range corresponding to the random access preamble resource of the first type of terminal device can be the same as the fourth frequency resource range. It can be understood that in this case, the fourth indication information is the third indication information, or the third indication information and the fourth indication information are different information, but indicate the same range.

[0240] In the embodiments of the present application, by configuring the maximum frequency resource range corresponding to the random access preamble resource of the first type terminal device, the third frequency resource including the PUCCH transmission, and the fourth frequency resource including the PUSCH transmission, the different channels can be designed and optimized according to the channel characteristics, thereby meeting the transmission requirements of each channel of the first type terminal device, especially the first type terminal device with low bandwidth capability.

As shown in the figure, for the second device, for example, in the initial access stage, the maximum frequency resource range for random access preamble resource transmission, the maximum frequency resource range for PUCCH transmission, and the maximum frequency resource range for PUSCH transmission can have different sizes, and one of the maximum frequency resources can be used as the initial uplink BWP of the second device.

[0244] For example, after the second device determines the frequency resource for transmitting the PUCCH, the PUCCH is transmitted in the third frequency resource. Correspondingly, the first device receives the PUCCH from the second device in the third frequency resource.

[0245] In the embodiments of the present application, the maximum frequency resource range corresponding to the random access preamble resource of the second device can be different from the maximum frequency resource range for PUSCH transmission and the maximum frequency resource range for PUCCH transmission. For the second device, for example, in the initial access stage, the maximum frequency resource range for random access preamble resource transmission, the maximum frequency resource range for PUCCH transmission, and the maximum frequency resource range for PUSCH transmission can have different sizes, and one of the maximum frequency resources can be used as the initial uplink BWP of the second device.

[0246] It should be noted that in the embodiments of the present application, the first device also configures the maximum frequency resource range of the PUCCH transmission and the maximum frequency resource range of the PUSCH transmission corresponding to the second type of terminal device. For example, in the random access process, the first device can configure the maximum frequency resource range of the PUCCH transmission and the maximum frequency resource range of the PUSCH transmission corresponding to the uplink initial BWP of the second type of terminal device, that is, for the second type of terminal device, the maximum frequency resource corresponding to the PUCCH transmission and the maximum frequency resource corresponding to the PUSCH transmission can be the same frequency resource. It can be understood that for the second type of terminal device, the configuration information for configuring the maximum frequency resource corresponding to the PUCCH transmission and the configuration information for configuring the maximum frequency resource corresponding to the PUSCH transmission can be the same information. Alternatively, the maximum frequency resource for transmitting the PUCCH of the second type of terminal device (also the maximum frequency resource for the second type of terminal device to transmit the PUSCH) can be the fourth frequency resource in the embodiments of the present application, that is, the maximum frequency resource for the first type of terminal device to transmit the PUSCH. Alternatively, the configuration information used by the first device to configure the maximum frequency resource range of the PUCCH transmission and the maximum frequency resource range of the PUSCH transmission corresponding to the second type of terminal device can be different from the second indication information, the third indication information, and the fourth indication information in the above.

[0247] In the embodiments of the present application, the frequency resource is composed of N continuous / discontinuous PRBs / RBs, and N is a positive integer. For example, the frequency domain resource is composed of N continuous PRBs / RBs. For example, the frequency resource can be a BWP.

[0248] In the embodiments of the present application, the M frequency resources for transmitting the PUCCH in the N second frequency resources can be enabled by the network device (as an implementation manner of the first device in the embodiments of the present application). For example, when the network device does not enable this feature, for the first type of terminal device, the number of frequency resources for transmitting the PUCCH is equal to the number of second frequency resources for transmitting the uplink data of the first type of terminal device, that is, M=N.

[0249] In the embodiments of the present application, the frequency resource range of the third frequency resource can be different from the frequency resource range of the fourth frequency resource, which can be enabled by the network device (as an implementation manner of the first device in the embodiments of the present application). For example, when the network device does not enable this feature, the frequency resource range of the third frequency resource is equal to the frequency resource range of the fourth frequency resource. It should be noted that the first frequency resource, the second frequency resource, the third frequency resource, and the fourth frequency resource in the embodiments of the present application can be used not only for transmitting the uplink data of the first type of terminal device in the RRC idle state, but also for transmitting the uplink data of the first type of terminal device in the RRC connected state or the inactive state.
