In addition, the initial uplink bandwidth part can be used for the physical uplink shared channel for transmitting information 3 in the random access process and for transmitting hybrid automatic repeat request feedback.

The frequency range of frequency hopping also needs to be guaranteed to be within the initial upstream bandwidth. Therefore, it is necessary for the NR terminal equipment to define the frequency range including the above-mentioned data transmission resources and frequency hopping resources, so as to ensure the establishment of a data transmission connection with the base station.

detailed description

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

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

Machine-type terminal equipment often has higher requirements on cost and power consumption. For example, machine-type terminal equipment is generally implemented at low cost, because the service in the application scenario corresponding to machine-type terminal equipment does not require high data transmission rate. For example, the data transmission rate carried by sensors under IWSN is not greater than 2Mbps. The data transmission rate carried by economical video surveillance cameras is generally 2 to 4 Mbps, and the peak downlink rate of terminal devices under wearable services, such as smart watches, does not exceed 150Mbps, and the peak uplink rate does not exceed 50Mbps, which is far lower than that of IWSN services. Due to the peak rate of NR legacy terminal equipment (such as NR eMBB terminal equipment), based on this, machine-type terminal equipment can reduce implementation specifications compared with NR legacy terminal equipment, thereby reducing implementation costs; on the other hand, reduce the implementation of machine-type terminal equipment. The cost also helps to expand the market for machine-type terminal equipment and promote the development of the IoT market. At present, 3GPP has launched research on low-capacity terminal equipment (NR reduced capability, NR RedCap) under the NR system (reference: RP-193238), aiming to target the growing IoT market, such as the aforementioned IWSN, video Monitoring and wearable business, design a terminal device that meets the performance requirements of the IoT market and has low cost/low implementation complexity to expand the application of NR systems in the IoT market. For the convenience of description, in the subsequent parts of this paper, NR RedCap UE is used as an example for description.

One way to reduce the cost of terminal equipment is to reduce the channel bandwidth of the terminal equipment, or it can also be understood as reducing the bandwidth capability of the terminal equipment, that is, the bandwidth capability of the NR RedCap UE can be much smaller than the bandwidth capability of the NR legacy terminal equipment. At present, NR Legacy terminal equipment such as version Rel-15/Rel-16 terminal equipment must have a bandwidth capability of 100MHz, while NR RedCap UE can receive the initial access signal sent by the NR base station and then access the NR system. , its bandwidth capability can be only 20MHz. Under certain NR system configurations, the bandwidth capability of NR RedCap UEs can be further reduced, for example, 5MHz or 10MHz. At this time, NR RedCap UEs can also access NR systems. Compared with the bandwidth capability of 100MHz, the bandwidth capability of not more than 20MHz can greatly reduce the cost of the RedCap UE.

The technical solutions of the embodiments of the present application can be applied to various communication systems, for example, fifth generation (5th generation, 5G) systems or new radio (NR), long term evolution (LTE) systems, LTE frequency Frequency division duplex (FDD) system, LTE time division duplex (TDD), universal mobile telecommunication system (UMTS), etc. The technical solutions of the embodiments of the present application may also be applied to device-to-device (device to device, D2D) communication and the like.

To facilitate understanding of the embodiments of the present application, a communication system applicable to the embodiments of the present application is first described in detail with reference to FIG. 1 and FIG. 2 .

FIG. 1 is a schematic diagram of a wireless communication system 100 suitable for an embodiment of the present application. As shown in the figure, the wireless communication system 100 may include at least one network device, such as the network device 111 shown in FIG. 1 , and the wireless communication system 100 may also include at least one terminal device, such as the terminal devices 121 to 121 shown in FIG. Terminal device 123. Both the network device and the terminal device can be configured with multiple antennas, and the network device and the terminal device can communicate using the multi-antenna technology.

Wherein, when the network device communicates with the terminal device, the network device can manage one or more cells, and each cell can provide services for at least one terminal device. In a possible implementation manner, the network device 111 and the terminal device 121 to the terminal device 123 form a single-cell communication system, and without loss of generality, the cell is denoted as cell #1. The network device 111 may be a network device in cell #1, or in other words, the network device 111 may serve a terminal device (eg, terminal device 121) in cell #1.

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

FIG. 2 is another schematic diagram of a wireless communication system 200 suitable for an embodiment of the present application. 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, such as the terminal device 201 to the terminal device 203 in FIG. 2 . The terminal device 201 to the terminal device 203 can communicate directly. For example, the terminal device 201 and the terminal device 202 may send data to the terminal device 203 individually or simultaneously.

It should be understood that the above-mentioned FIG. 1 and FIG. 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 random access scenarios (such as 5G NR random access procedures).

It should also be understood that the network device in the wireless communication system may be any device having a wireless transceiver function.

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

The short format occupies 1-2 symbols and can carry 1-2 bits of information, and the long format occupies 4-14 symbols and can carry information larger than 2 bits. The purpose of introducing the short-format PUCCH in NR is to shorten the delay of Hybrid Automatic Repeat-Request Acknowledgement (HARQ-ACK) feedback, while the long-format can still ensure coverage considering the long duration.

In NR, taking into account the flexibility of system configuration, all PUCCHs with more than or equal to 2 symbols can be configured with frequency hopping, including intra-slot and inter-slot frequency hopping. The number of symbols in the first hop during frequency hopping is 1, and the remaining symbols are in the second hop.

PUCCH formats 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.

2. Physical uplink shared channel

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.

3. Control resource collection

The control resource set (Control-Resource Set, CORESET) mainly indicates the number of symbols (time domain) and RBs (frequency domain) occupied by the physical downlink control channel, that is, the CORESET indicates the frequency domain resources including the PDCCH. CORESET contains several 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 CORESET0 can be used for the remaining minimum system information (Remaining Minimum System Information, RMSI) (It can also become the scheduling of System Information Block Type 1 (SIB1).

4. Physical downlink control channel

The Physical Downlink Control Channel (PDCCH) carries scheduling and other control information, including transmission format, resource allocation, uplink scheduling grant, power control, and uplink retransmission information. The PDCCH channel is a set of physical resource elements, which carry uplink and downlink control information. According to different scopes, the PDCCH carries information to distinguish common control information (common search space) and dedicated control information (dedicated search space).

5. Main Information Block

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

6. Radio resource control status

RRC state, the terminal equipment has three RRC states: RRC connected state, RRC idle state and RRC inactive state.

RRC connected state (or, it can also be referred to as connected state. In this paper, "connected state" and "RRC connected state" are the same concept, and the two terms can be interchanged): the terminal device and the network establish an RRC connection for data transfer.

RRC idle state (or, it can also be referred to as idle state. In this paper, "idle state" and "RRC idle state" are the same concept, and the two terms can be interchanged): the terminal device does not establish RRC with the network connection, 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 the RRC connection establishment process.

RRC inactive state (or, may also be referred to simply as inactive state. In this document, "inactive state", "deactivated state", "inactive state", "RRC inactive state" or "RRC deactivated state" etc., are the same concept, and these terms can be interchanged): the terminal device entered the RRC connection state at the anchor base station before, 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 re-enter the RRC connected state from the RRC inactive state, it needs to initiate an RRC connection recovery process (or referred to as an RRC connection re-establishment process) at the base station where it currently resides. Because the terminal device may be in a mobile state, the base station where the terminal device currently resides and the anchor base station of the terminal device may be the same base station, or may be different base stations. Compared with the RRC establishment process, the RRC recovery process has shorter delay and lower signaling overhead. However, the base station needs to save the context of the terminal device, which will occupy the storage overhead of the base station.

7. System message block

System Information Block (SIB) is the system information broadcast by the base station, which is divided into various types, so that it can be sent on different frequencies. There are 19 types of SIBs in total, and the scheduling information of SIBs is carried through MIBs or SBs.

In order to ensure data transmission with the NR base station, the terminal equipment needs to establish a connection with the NR base station through the random access process, so that the NR base station can identify the terminal equipment and complete subsequent data transmission. Taking the initial access as an example, the NR Legacy terminal device is in the idle state (idle state), and by receiving the synchronization signal block (SSB) sent by the NR base station, it can realize time-frequency synchronization with the NR base station and obtain the synchronization signal block (SSB). The initial access configuration information of the cell corresponding to the NR base station, that is, the system information block 1 (system information block 1, SIB1) information. The continuous bandwidth resource, which is defined in the current protocol as the initial upstream bandwidth part (bandwidth part, BWP). The initial uplink BWP can be used for the physical uplink shared channel (PUSCH) for transmitting message 3 (message 3, Msg3) in the random access process, and for transmitting information A (message A, message A, PUSCH) in the random access process. Msg A) and the physical uplink control channel (PUCCH) for transmitting hybrid automatic repeat request (HARQ) feedback, wherein the HARQ feedback is the information 4 (message 4) in the random access process. , Msg 4) or the feedback for message B (message B, Msg B) in the random access process, in addition, the physical random access channel (physical random access channel, PRACH) resources in the random access process must also be in the Transmission in the upstream initial BWP. Further, the terminal device can also ensure the data transmission performance with 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. It also needs to be guaranteed to be within the initial upstream BWP. Therefore, it is necessary for the NR terminal equipment to define the frequency range including the above-mentioned data transmission resources and frequency hopping resources, so as to ensure the establishment of a data transmission connection with the base station.

It should be understood that the form of the uplink initial BWP here may not only be a set of frequency resources for ensuring random access data transmission, but also may be used for data transmission in other scenarios.

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

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 its uplink initial BWP for the RedCap UE.

FIG. 3 is an architectural diagram of system data transmission in a random access phase. In the prior art, first, in the random access phase, the frequency resource configuration of the initial uplink BWP is included in the SIB1 information. Before receiving the SIB1 information, the data transmission between the terminal device and the base station is shown in Figure 3, and it can be observed that , the terminal equipment does not send uplink information before receiving the SIB1 information, that is, there is no interaction between the cells corresponding to the NR base station, so the NR base station (or network side equipment) cannot obtain the type of terminal equipment, that is, it is uncertain to receive SIB1 information The terminal device is a terminal device with a bandwidth capability of 100MHz or a terminal device with a bandwidth capability of not more than 20MHz (for example, an NR RedCap terminal device). This will lead to the following problems in the prior art:

(1) The uplink initial BWP bandwidth configured by the network equipment exceeds the bandwidth capability of the NR RedCap UE, resulting in the inability of the NR RedCap terminal equipment to access.

For example, the initial uplink BWP includes PRACH resources. 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 SSB and PRACH resources (such as preamble preamble). The UE can select the corresponding preamble to initiate random access according to the detected SSB and the correspondence between SSB and preamble. , the network device can determine the SSB beam direction detected by the UE that initiated the preamble through the received preamble, and before establishing a radio resource control (radio resource control, RRC) connection with the UE, through the SSB beam direction corresponding to the preamble, to The UE sends downlink data, so that the downlink data transmission performance can be guaranteed. However, since the total PRACH resource bandwidth configured by the network equipment will exceed 20MHz, the NR RedCap UE will not be able to select the PRACH resource corresponding to the optimal SSB beam direction, which will affect the data transmission performance of the RedCap UE, and even cause the RedCap UE to be unable to access.

(2) Limit the uplink initial BWP bandwidth corresponding to the NR Legacy UE, which affects the initial access performance of the NR Legacy UE.

Considering the possible existence of NR RedCap UEs in the system, when configuring the initial uplink BWP bandwidth, the network device can configure the initial uplink BWP bandwidth to a value not greater than the bandwidth capability of the NR RedCap UEs, so as to ensure the access of the RedCap UEs. However, this will limit the performance of legacy UE access. For example, as mentioned above, the UE can determine the frequency hopping resource range of the uplink transmission channel according to the size of the uplink initial BWP, and limit the bandwidth of the uplink initial BWP, which will reduce the hop of the uplink transmission channel. The range of frequency resources affects 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 legacy UE access. For example, for an NR Legacy UE, the initial uplink BWP can be configured to a maximum of 100MHz. If it is considered that 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, and the bandwidth reduction of the uplink initial BWP will be reduced. NR Legacy UE access capacity.

FIG. 4 is a schematic diagram of a resource load of a data transmission frequency resource. Wherein, the first type of terminal equipment can be a low-cost, low-bandwidth terminal equipment, such as NR RedCap UE, and the second type of terminal equipment can be a traditional terminal equipment (NR Legacy UE, such as NR eMBB UE). As shown in the figure, due to the limitation of the bandwidth capability of the first type of terminal equipment, the data transmission frequency resources used in the disconnected state cannot exceed the bandwidth capability of the first type of terminal equipment in one way, so that in the disconnected state For example, in the initial access stage, the data transmission between the network device and the first-type terminal device can only be concentrated in the frequency range corresponding to the bandwidth capability of the first-type terminal device. Considering that, in a disconnected state such as the initial access stage, the network device cannot identify each first type terminal device, so it is impossible to individually configure data transmission frequency resources for each first type terminal device through the dedicated signaling of the terminal device. , which will result in that the first type of terminal equipment that aims to establish an RRC connection with the network equipment in the non-connected state will be concentrated in a frequency range, for example, 20MHz. Considering that in the disconnected 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 equipment in the connected state, under certain conditions It will also fall back to the corresponding data transmission frequency resource in the disconnected state to complete the data transmission with the network device. This will result in an excessive load on the data transmission frequency resources in the disconnected state, especially when considering the large number of connections of the first type terminal equipment, the load on the data transmission frequency resources will be further increased. For the second type of terminal equipment, the above problem does not exist, because the required bandwidth capability of the second type of terminal equipment is 100MHz, so the network equipment can configure data transmission frequency resources with a relatively large frequency resource range.

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

1. Different bandwidth capabilities. For example, the second type terminal equipment can support the simultaneous use of 100MHz frequency domain resources and network equipment on one carrier for data transmission, while the first type terminal equipment can support the maximum simultaneous use of 20MHz, 10MHz or 5MHz frequency domain resources and network equipment for data transmission.

2. The number of transceiver antennas is different. For example, the minimum supported antenna configuration of the second type terminal equipment is 4 transmit and 2 receive, that is, under the minimum antenna configuration, 4 receiving antennas are used to receive downlink data, and 2 transmitting antennas are used to send uplink data; while the first type terminal equipment supports the maximum The antenna configuration is lower than 4 transmissions and 2 receptions. For example, the first type terminal equipment UE only supports 2 receptions and 1 transmission, or can also support 1 reception and 1 transmission, or can also support 2 receptions and 2 transmissions.

3. The uplink maximum transmit power is different. For example, the maximum uplink transmit power of the second type of terminal equipment may be 23 dBm or 26 dBm, while the maximum uplink transmit power of the first type of terminal equipment may be a value between 4dBm and 20dBm.

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

5. The first type terminal equipment and the second type terminal equipment support different carrier aggregation (carrier aggregation, CA) capabilities. For example, the second type of terminal equipment may support carrier aggregation, but the first type of terminal equipment does not support carrier aggregation; for another example, both the first type of terminal equipment and the second type of terminal equipment support carrier aggregation, but the second type of terminal equipment supports both. The maximum number of carrier aggregations is greater than the maximum number of carrier aggregations simultaneously supported by the first type of terminal equipment. For example, the second type of terminal equipment can support aggregation of up to 5 carriers or 32 carriers simultaneously, while the first type of terminal equipment can simultaneously support aggregation of up to 2 carriers.

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

7. The processing capability of the second type of terminal equipment is different from that of the first type of terminal equipment. The processing capability of the first type of terminal equipment is lower than that of the second type of terminal equipment. For example, the terminal device of the first type and the terminal device of the second type have different processing time capabilities for data. For example, the minimum delay between receiving downlink data and sending feedback on the downlink data by the second type terminal equipment is smaller than the minimum delay between receiving downlink data and sending feedback on the downlink data by the first type terminal equipment. The minimum delay between the second type terminal equipment sending the uplink data and receiving the feedback of the uplink data is smaller than the minimum delay time between the first type terminal equipment sending the uplink data and receiving the feedback of the uplink data. For another example, the maximum transmission block size (transmission block size, TBS) that can be processed by the terminal device of the first type is smaller than the TBS that can be processed by the terminal device of the second type. For another example, the maximum downlink modulation order (for example, 64QAM) that the first type terminal equipment can handle is smaller than the maximum downlink modulation order (for example, 256QAM) that the second type terminal equipment can handle, and/or the first type terminal equipment can handle. The maximum uplink modulation order (for example, 64QAM or 16QAM) is smaller than the maximum uplink modulation order (for example, 256QAM or 64QAM) that the second type terminal equipment can handle. For another example, the number of hybrid automatic repeat requests (hybrid Automatic Repeat reQuest, HARQ) supported by the terminal device of the first type is less than the number of HARQs supported by the terminal device of the second type.

8. The transmission rate of the peak uplink (or downlink) transmission of the second type of terminal equipment is different from the peak uplink (or downlink) transmission rate corresponding to the first type of terminal equipment. The peak uplink (or downlink) transmission rate corresponding to the terminal equipment of the first type is lower than the peak transmission rate of the uplink (or downlink) transmission of the terminal equipment of the second type.

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

FIG. 5 shows a system architecture diagram of a wireless access applicable to an embodiment of the present application. As shown in the figure, the network device and the terminal device of the present application are connected through an air interface.

In this application, a terminal device, including a device that provides voice and/or data connectivity to a user, may for example include a handheld device with wireless connectivity, or a processing device connected to a wireless modem. More specifically, for example, it may be an LTE terminal, a 5G terminal, and a UE.

Network devices, including access network (AN) devices, such as base stations (eg, access points), may refer to devices in the access network that communicate with wireless terminal devices through one or more cells over the air interface. Optional, for example, can be: LTE eNB/HeNB/Relay/Femto/Pico, 5G base station.

Description of the terminal device: In this application, the terminal device may also include a relay Relay, and a terminal device that can perform data communication with a network device may be regarded as a terminal device.

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

It should be noted that, in this application, although low-capacity or low-cost or low-complexity terminal equipment is used as an example for description, the enumerated embodiments are also applicable to other types of terminal equipment, such as NR Rel-17 or and later terminal equipment. For ease of description, this application takes the NR RedCap UE as an example for description.

It should be noted that in this application, the data transmission frequency resources, or the maximum frequency resources used for PUSCH transmission, the maximum frequency resources used for PUCCH transmission, and the maximum frequency resources used for NR RedCap UE preamble transmission are all determined by continuous It consists of resource blocks (RBs).

The various embodiments provided by the present application will be described in detail below with reference to the accompanying drawings.

FIG. 6 is a schematic flowchart of a wireless access method applicable to an embodiment of the present application. Method 600 may include the following steps.

In the following embodiments, in order to distinguish and without loss of generality, the first device is used to represent the network device, and the second device is used to represent the first type of terminal device, such as NR RedCap UE.

It should be understood that the first device may also have other forms, for example, both the first device and the second device may be first-type terminal devices, or the first device may also be a second-type terminal device (NR Legacy UE, such as NR eMBB UE), the second device may be the first type of terminal device. There is no limitation here.

It should be understood that in this application, the main difference between the first type of terminal equipment and the second type of terminal equipment lies in the different bandwidth capabilities. However, in the specific implementation process, the difference between the first type of terminal equipment and the second type of terminal equipment is not limited to bandwidth. Different capabilities, ie, different bandwidth capabilities, is not a required distinguishing feature.

S601 The first device determines a first frequency resource.

Exemplarily, the first device may determine a first frequency resource, where the first frequency resource includes a frequency resource used for transmitting the physical uplink control channel PUCCH, and the first frequency resource is one of M frequency resources used for transmitting the PUCCH. One frequency resource, the M frequency resources used for transmitting PUCCH are M frequency resources among the N second frequency resources, and the second frequency resources are used for transmitting the uplink data of the first type terminal equipment, wherein M is less than N, M and N are all positive integers.

It should be understood that, in this embodiment of the present application, the second frequency resource may be used to transmit random access uplink data of the first type terminal equipment, and may also be used for random access uplink data of the second type terminal equipment.

It should be understood that, in this embodiment of the present application, when the first device determines the first frequency resource, although the first frequency resource is one frequency resource among M frequency resources for transmitting PUCCH, the M The frequency resources used for PUCCH transmission are M frequency resources among the N second frequency resources. However, the first device may directly determine the frequency resources used for PUCCH transmission without determining the second frequency resources.

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

Taking random access as an example, defining N second frequency resources for uplink data transmission of the first type terminal equipment can realize service load balancing, which is especially beneficial for the large connection first type terminal equipment.

In addition, defining M second frequency resources among the N second frequency resources includes PUCCH transmission (where M is less than N), which can reduce the performance impact of PUCCH transmission, especially PUCCH frequency hopping transmission, on PUSCH transmission of other terminal devices in the system, for example , which affects the PUSCH transmission performance of legacy UEs or broadband UEs in the system (for example, the channel bandwidth capability is 100MHz); on the other hand, considering that PUCCH can support multi-user multiplexing transmission, it is not necessary to include the PUCCH transmission, in this way, the PUCCH overhead can be reduced under the condition of ensuring the multi-user HARQ-ACK transmission performance.

In a possible implementation manner, only one frequency resource among the N second frequency resources includes a frequency resource for PUCCH transmission, which can further reduce the transmission overhead of PUCCH. Further, in a possible implementation manner, when only one frequency resource in the N second frequency resources includes a frequency resource for PUCCH transmission, the first frequency resource is that the N second frequency resources include the highest frequency or the frequency resource. lowest frequency resource. Taking N=3 as an example, it is assumed that the range of frequency resources included in one of the three second frequency resources corresponds to a CRB indexed by a common resource block (CRB) p1 and a CRB indexed by p2. The range of frequency resources composed of CRBs, the range of frequency resources included by another second frequency resource corresponds to the range of frequency resources composed of the CRB whose CRB index is p3 and the CRB whose CRB index is p4, and there is another second frequency resource that includes The frequency resource range corresponds to the frequency resource range composed of the CRB whose CRB index is p5 and the CRB whose CRB index is p6, where p1<p2<p3<p4<p5<p6, which includes the frequency resources used for PUCCH transmission or the first frequency The resource may correspond to a frequency resource whose frequency starting point is CRB index p1 and whose frequency ending point is CRB index p2, or the frequency resource including the frequency resource used for PUCCH transmission or the first frequency resource may also correspond to a frequency starting point whose CRB index is p5 and whose frequency ending point is The frequency resource of the CRB index p6. Here, the CRB is a resource block determined relative to the system carrier point A, and the system carrier point A may correspond to the lowest frequency subcarrier included in the lowest frequency resource block included in the system carrier, or correspond to the subcarrier included in the system carrier bandwidth. The frequency domain resource unit with the lowest frequency, wherein the frequency domain resource unit with the lowest frequency includes the corresponding subcarrier with the lowest frequency within the carrier bandwidth of the system. Or 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 N second frequency resources include the frequency resource with the lowest frequency, and the second frequency resource including the highest frequency subcarrier may be understood as the N second frequency resources including the frequency resource with the highest frequency. Alternatively, in this application, the highest frequency or the lowest frequency may also be determined by using the absolute frequencies corresponding to the frequency resources included in the N second frequency resources to determine the highest frequency or the lowest frequency. Alternatively, other methods may also be used, which are not specifically limited. In order to ensure the performance of PUCCH transmission, PUCCH generally adopts the method of frequency hopping. Therefore, limiting the first frequency resource including PUCCH transmission to the frequency resource with the highest frequency or the lowest frequency among the N second frequency resources can reduce the impact on other terminal equipment. Influence of PUSCH transmission performance, other terminal devices are, for example, second type terminal devices, terminal devices with large bandwidth capability (for example, 100MHz), Legacy terminal devices, and so on.

In a possible implementation manner, the first frequency resource has the following characteristics: the first frequency resource is a resource with the highest frequency or the lowest frequency included in a specific frequency resource as the first frequency resource, for example, the first frequency resource is a specific frequency A continuous frequency resource within the 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 may be the system uplink carrier corresponding to the first type terminal equipment or the system uplink carrier corresponding to the second type terminal equipment, the system uplink carrier corresponding to the first type terminal equipment or the system uplink carrier corresponding to the second type terminal equipment Can be the same or not. Alternatively, the specific frequency resource may also be the uplink initial BWP corresponding to the second type terminal equipment, or the specific frequency resource may also be the uplink channel transmission bandwidth corresponding to the first type terminal equipment or the uplink channel transmission bandwidth corresponding to the second type terminal equipment. . In order to ensure the performance of PUCCH transmission, PUCCH generally adopts frequency hopping. Therefore, configuring the first frequency resource including PUCCH transmission on one side of the frequency resource of the specific frequency resource can reduce the impact on other terminal devices in the system, such as the second type. Influence of the data transfer rate of the end device.

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

The first device may notify the second device of the first frequency resource by means of broadcasting information notification or by means of RRC dedicated signaling, which is not limited in this application. Alternatively, the first device may further indicate the first frequency resource through physical layer signaling.

S602, the first device sends the first indication information to the second device.

For example, the first device sends first indication information, where 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.

Specifically, an implementation manner is that, when the first device configures the N second frequency resources, the first frequency resource including the transmission of the PUCCH is implemented by means of the second frequency resource identification. For example, the first device notifies N second frequency resources by means of broadcast information, but only one includes the frequency resources used for PUCCH transmission. When configuring N second frequency resources, the first device can configure the second frequency resources at the same time. The identification information corresponding to the resource is used to indicate whether the second frequency resource includes a PUCCH resource. In an implementation manner, the first device may indicate which second frequency resource includes the PUCCH resource by configuring the second frequency resource index including the PUCCH resource. For example, the first device is configured with four second frequency resources, and the corresponding second frequency resource indices are 0, 1, 2, and 3. In this implementation manner, the first device configures the second frequency resources including PUCCH resources. The index is any one of the second frequency resource indices 0-3; or the first device may directly configure whether the N second frequency resources include PUCCH resources, so as to indicate the second frequency resources including PUCCH resources. For example, the first device is configured with 4 second frequency resources, and the frequency resource indices are 0-3 respectively. At the same time, the first device only configures PUCCH resources for the second frequency resources whose frequency resource index is 0, and for other second frequency resources, No PUCCH resource is configured. The first frequency resource can be determined by identifying the frequency resource used to transmit the PUCCH in the resource configuration.

In a possible implementation manner, the first device may notify the second device of the configuration information of the first frequency resource and/or the information of the resource index for PUCCH transmission by means of broadcast information notification.

In this embodiment of the present application, the configuration information of the first frequency resource includes at least one of the following: a frequency resource location of the first frequency resource (including a bandwidth size and a frequency starting location), a configuration for PUCCH transmission in the first frequency resource information, the configuration information of PUCCH transmission includes at least one of the following: PUCCH transmission format, the number of symbols corresponding to PUCCH transmission, frequency resources for PUCCH transmission, and code resources for PUCCH transmission.

In an implementation manner, the first device may directly notify the configuration information of the first frequency resource, which may be specifically notified through system broadcast information, RRC dedicated signaling, or physical layer signaling, or may also use other methods, which are not specified in detail. limited. In another implementation manner, the first device may configure N second frequency resources, and indicate the identification information of the second frequency resources corresponding to the first frequency resources to configure the first frequency resources. For example, the first device is configured with 4 second frequency resources, wherein the second frequency resource whose second frequency resource index is 0 is identified as a frequency resource including a PUCCH resource (the specific implementation is the same as the above-mentioned embodiment), and is identified as a frequency resource including a PUCCH resource. The second frequency resource of the PUCCH resource may be determined as the first frequency resource.

In another implementation manner, the first device may also notify resource index information used for PUCCH transmission, where the resource index information may correspond to frequency resource information used for PUCCH transmission, such as resource block information.

Specifically, for example, the first device may indicate the configuration information of the first frequency resource and/or the information of the resource index used for PUCCH transmission 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 may be information carried by a physical broadcast channel (PBCH), for example, the information included in the MIB, or the information included in the control information for scheduling the transmission of the system information block SIB or the SIB. Information included in the information, wherein the control information for scheduling SIB transmission may be carried in the PDCCH, and the SIB information may be carried in the PDSCH.

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

Specifically, when the second device falls back to the RRC inactive state, the first device can configure the information of the target frequency resource and/or the information of the resource index used for PUCCH transmission through RRC dedicated signaling, which can be used for the second device. The device can perform data transmission with the first device through the first frequency resource when the device is in a disconnected state.

In a possible implementation manner, the first device may further indicate configuration information of the first frequency resource and/or information of a resource index used for PUCCH transmission through physical layer signaling.

Preferably, the first device can send the configuration information of the first frequency resource to the second device through Location And Bandwidth for RedCap UE included in SIB1, or send the configuration information of the first frequency resource to the second device through other information included in SIB1 equipment. Alternatively, the first device may 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 Msg2 or Msg4 during the random access process.

S603, the second device determines the first frequency resource.

For example, the second device may determine the first frequency resource according to the received first indication information sent by the first device.

In a possible implementation manner, when the indication information is used to indicate the resource index for transmitting PUCCH, the second device needs to determine the resource block for transmitting PUCCH according to the resource index for transmitting PUCCH, and determine the resource block for transmitting PUCCH according to the resource block for transmitting PUCCH. The first frequency resource, wherein the first frequency resource includes the resource block for transmitting the PUCCH. Preferably, the first frequency resource includes a frequency resource with the highest frequency or the lowest frequency among the at least two first frequency resources.

FIG. 7 is a schematic diagram of a frequency resource for PUCCH transmission applicable to an embodiment of the present application. As shown in the figure, in this embodiment, there are two second frequency resources, and only one second frequency resource includes PUCCH transmission (corresponding to the second frequency resource #1 in the figure), the second frequency resource #2 does not include frequency resources for PUCCH transmission. It should be understood that in the frequency resources including PUCCH transmission, in addition to the frequency resources used for PUCCH transmission, frequency resources used for PUSCH transmission may also be included. In a possible implementation manner, among the two second frequency resources, one second rate resource (ie, second frequency resource #1) may correspond to the uplink initial BWP of the first type terminal device, such as a RedCap terminal device.

Among the at least two second frequency resources, only one second frequency resource includes PUCCH resources, which can reduce control channel overhead. Considering that the data carried on the PUCCH can realize multi-user multiplexing through frequency division multiplexing (FDM), multi-user multiplexing can also be realized through code division multiplexing (CDM). In the non-connected state, the data transmission carried on the PUCCH is mainly for the HARQ-ACK feedback of the downlink data. Based on the above two points, the PUCCH transmission resource has a smaller resource overhead compared with the PUSCH transmission resource, so each first frequency is not required. The resources all include PUCCH resources, so that for the first frequency resource that does not include PUCCH, a certain peak rate of uplink data transmission can be guaranteed. In addition, if only one second frequency resource includes PUCCH transmission, the impact on the data transmission performance of the NR Legacy UE will also be relatively small. This is because at least two second frequency resources are FDM in frequency, but some frequency resources may overlap. If each second frequency resource includes PUCCH resources, considering that the PUCCH resources are shown in the figure, Generally, the bandwidth is small, and in order to ensure the performance on both sides of the second frequency resource, there will be multiple narrow-band and discrete PUCCH resources in one carrier bandwidth, which will affect the continuous resource size and size of the uplink data transmission of the NR Legacy UE. Allocation of resource block groups (RBGs). With this embodiment, even if there are at least two second frequency resources for NR RedCap UEs, only one second frequency resource includes one PUCCH resource, which not only ensures the data transmission performance of NR RedCap UEs, but also reduces the impact on NR RedCap UEs. The impact of legacy UE data transmission performance.

It should be understood that the data transmission frequency resource transmitted by the PUCCH may correspond to the uplink initial BWP of the RedCap UE.

For example, the second device may 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.

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

For example, the number of the second frequency resources may be associated with the transmission bandwidth for the downlink system information of the second type of terminal equipment, and the larger the bandwidth, the larger the number N.

For example, the number of second frequency resources may be associated with frequency resources used to transmit random access uplink data of the second type of terminal equipment.

For example, the number of the second frequency resources may be associated with the carrier bandwidth notified by the first device or the frequency band where the system carrier is located.

For example, the second device may be based on the bandwidth of the system carrier, the frequency band where the system carrier is located, the frequency resources used for transmitting the random access uplink data of the second type terminal equipment, and the downlink system information used for transmitting the second type terminal equipment. The number N of the second frequency resources is determined by one or more of the transmission bandwidths, which is not limited in this application. Wherein, the transmission bandwidth used for transmitting the downlink system information of the second type terminal equipment may be the transmission bandwidth of the downlink initial BWP corresponding to the second type terminal equipment, for example, corresponding to CORESET#0 indicated by the pdcch-ConfigSIB1 control field in the MIB frequency domain resources.

For example, the second device may determine the second frequency resources according to the number of the second frequency resources and the frequency resources used for transmitting the random access uplink data of the second type terminal device, for example, determine the frequency position of each second frequency resource .

For example, the second device may determine the position of each second frequency resource according to the number of second frequency resources and the number of random access preamble RACH resources.

S604, the second device transmits the PUCCH to the first device in the first frequency resource.

Exemplarily, after the second device determines the first frequency resource including the frequency resource for transmitting the PUCCH, the second device may transmit the PUCCH through the first frequency resource, and the first device receives the first frequency resource from the second device within the first frequency resource. Data carried by PUCCH.

It should be understood that this embodiment takes one terminal device in the first type of terminal device, that is, the second device as an example, however, the first frequency resource may be a frequency resource suitable for the first type of terminal device.

FIG. 8 is another schematic flowchart of a method for uplink data transmission applicable to an embodiment of the present application. Method 800 may include the following steps.

In the following embodiments, for the sake of distinction and without loss of generality, the first device is used to represent the network device, and the second device is used to represent the first type of terminal device (for example, NR RedCap UE).

S801 The first device determines a third frequency resource.

Exemplarily, the first device may determine a third frequency resource, where the third frequency resource is a frequency resource used for PUCCH transmission or is understood to include a frequency resource used for PUCCH transmission, wherein 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 the fourth frequency resource, and the fourth frequency resource includes the frequency resource for transmitting the PUSCH. Alternatively, it can also be understood that the maximum frequency resource range used for PUCCH transmission is different from the maximum frequency resource range used for PUSCH transmission.

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

In the prior art, when the terminal device and the network device perform data transmission, the frequency resource for transmitting PUCCH (which may correspond to the third frequency resource) and the frequency resource for transmitting PUSCH (which may correspond to the fourth frequency resource) may be the same frequency resource. That is, if the frequency resources used for PUSCH transmission also include frequency resources used for PUCCH transmission, the maximum frequency resource range used for PUCCH transmission is the same as the frequency resource range used for PUSCH transmission. For example, in the prior art, a terminal device performs data transmission with a network device through an activated BWP at any time, and the frequency resource range of the PUSCH transmission resource in the BWP can be the RB with the lowest frequency to the highest frequency included in the BWP. The frequency resource range composed of RBs, although the frequency resource range of the PUCCH transmission resources in the BWP can be configured, the configurable frequency resource range can also be included in the BWP from the lowest frequency RB to the highest frequency RB. The composition of the frequency resource range. In addition, in general, in order to ensure the performance of PUCCH transmission, the terminal equipment will use the PUCCH frequency hopping transmission method in the time slot, so that the PUCCH transmission can obtain the frequency diversity gain. For example, the PUCCH can determine the specific frequency of transmission in the time slot in the following way Resource (represented by PRB), where in a time slot, the PRB index corresponding to the frequency resource of the first hop PUCCH is

The physical resource block (PRB) index corresponding to the frequency resource of the second-hop PUCCH is:

where C is related to the PUCCH resource index and the total number of initial cycle indices allocated for PUCCH resources,

the PRB or RB corresponding to the PRB index used for PUCCH transmission configured for the terminal device by the network device,

The size of the BWP frequency domain resources including the PUCCH transmission can also be understood as the BWP frequency resource range, where 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 PUCCH transmission is the BWP frequency resource size including the PUCCH transmission or the BWP frequency resource range (for example, when

and C=0). Considering that the BWP may also include PUSCH transmission, the network device may schedule the PUSCH frequency resources of the terminal device to be distributed in the entire BWP. For terminal equipment with unlimited bandwidth, such as NR Legacy terminal equipment (which may correspond to the second type of terminal equipment in this embodiment of the present application), since its bandwidth can reach 100 MHz, the maximum frequency resource range used for PUCCH transmission and the The maximum frequency resource range of PUSCH transmission can be both 100MHz, which can not only achieve PUCCH frequency hopping gain but also 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 this embodiment of the present application), since its bandwidth capability is limited, for example, only 20 MHz, in order to ensure the PUCCH frequency hopping transmission performance , the maximum range of the third frequency resource including PUCCH transmission can only be the channel bandwidth of the terminal device, such as 20MHz, so using the existing technology will lead to the maximum frequency resource range of PUSCH transmission can only be 20MHz, which will limit the PUSCH The frequency selection scheduling gain of transmission, generally, the larger the maximum frequency resource range used for transmitting PUSCH, the greater the flexibility of PUSCH transmission scheduling, and the more frequency selection scheduling gain can be obtained. Based on this, in the embodiments of the present application, for the first type of terminal equipment, the frequency resources used to transmit the PUCCH of this type of terminal equipment, that is, the frequency resource range of the third frequency resource may be different from the frequency used to transmit the PUSCH of this type of terminal equipment The resource is the frequency resource range of the fourth frequency resource. For the first type of terminal equipment, by decoupling the third frequency resource and the fourth frequency resource, it can not only ensure the realization of PUCCH frequency hopping, but also ensure the frequency selection scheduling gain of PUSCH transmission. Optimization is performed to improve the data transmission performance of the first type terminal device.

In a possible implementation manner, 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 the PUSCH.

In a possible implementation manner, the size of 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 20MHz, then the frequency resource of the third frequency resource The range is 20MHz. In this way, the PUCCH frequency hopping gain can be guaranteed, and the number of symbols transmitted by the PUCCH can be not affected. Conversely, if the size of the frequency resource range of the third frequency resource is greater than the bandwidth capability of the first type of terminal device, considering the PUCCH transmission, the first type of terminal device needs to consider between the first hop PUCCH and the second hop PUCCH Radio frequency (RF) retuning time, the RF retuning time generally corresponds to several orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbols, that is, within the RF retuning time, the first type The terminal device cannot perform data transmission with the network device (corresponding to the first device in the embodiment of the present application), which will reduce the number of symbols used for PUCCH transmission in one time slot, thereby affecting the PUCCH transmission performance.

FIG. 9 is a schematic diagram of a frequency resource range applicable to an embodiment of the present application. As shown in the figure, the maximum frequency resource range used by the first type terminal equipment for PUSCH transmission is different from the maximum frequency resource range used for PUCCH transmission. For example, the maximum frequency resource range used for PUSCH transmission may be larger than the maximum frequency resource range used for PUCCH transmission. Frequency resource range. Wherein, within the maximum frequency resource range for PUCCH transmission, other resources not allocated for PUCCH transmission can be used for PUSCH transmission. It should be noted that the maximum frequency resource range used for PUSCH transmission means that the PUSCH transmission resources scheduled by the network device to the first-type terminal device can be distributed in any one or more frequency domain resource units included within this maximum frequency resource range. For example on RB. In addition, in FIG. 9, within the range of the maximum frequency resources used for PUCCH transmission, the frequency resources used for PUCCH transmission are only an exemplary implementation manner, and the frequency resources of PUCCH transmission between the first type terminal equipment and the network equipment are also It may be distributed to other frequency domain resource units such as RBs included in the maximum frequency resource range for PUCCH transmission.

FIG. 10 is another schematic diagram of a frequency resource range applicable to an embodiment of the present application. As shown in the figure, it should be noted that the maximum frequency resource used for PUSCH transmission mentioned here may refer to the resource range between the minimum frequency position that can be occupied for transmitting PUSCH and the maximum frequency position that can be occupied.

In this embodiment of the present 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 also include the maximum frequency resource range used for PUCCH transmission. There is no overlap between the maximum frequency range, or the maximum frequency resource range for PUSCH transmission and the maximum frequency resource range for PUCCH transmission, eg, distributed by frequency division multiplexing (FDM).

Exemplarily, the frequency resource in the embodiment of the present application may correspond to a BWP, for example, 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 terminal equipment of the first type determines the PUCCH transmission resources through the above formula, the PUCCH transmission resources corresponding to the second hop are

middle

The corresponding size is the third BWP size (for example, the third BWP size may be the number of frequency domain resource units included in the third BWP). When the first type terminal device determines the PUSCH transmission resource, it determines the location of the PUSCH transmission resource according to the fourth BWP. Further, if the first device enables PUSCH frequency hopping transmission of the first type of terminal device, the first type of terminal device may be based on the fourth BWP size (for example, the fourth BWP size may be the frequency domain resource unit included in the fourth BWP). number) to determine the frequency resource corresponding to the PUSCH frequency hopping transmission.

It should be noted that, in this embodiment of the present application, the maximum frequency resource range used for PUCCH transmission does not mean that all frequency resources are used to transmit PUCCH within the frequency resources including PUCCH transmission (for example, the third frequency resource). It refers to the frequency resource range corresponding to the lowest frequency RB corresponding to PUCCH transmission and the highest frequency RB corresponding to all frequency resources that may be used for PUCCH transmission within the frequency resources (such as the third frequency resource) including PUCCH transmission. It is regarded as the maximum frequency resource range used for transmitting PUCCH. Taking BWP as an example, combined with the above formula, it can be found that among all the frequency resources that may be used for PUCCH transmission, the range of frequency resources corresponding to the RB with the lowest frequency and the RB with the highest frequency corresponding to PUCCH transmission is the BWP corresponding to PUCCH transmission. range of frequency resources.

It should be noted that, in this embodiment of the present application, the maximum frequency resource range used for PUSCH transmission does not refer to the frequency resources including PUSCH transmission (for example, the fourth frequency resource), all frequency resources are used for PUSCH transmission, It refers to the frequency resource range corresponding to the lowest frequency RB corresponding to PUSCH transmission and the highest frequency RB corresponding to all frequency resources that may be used for PUSCH transmission within the frequency resources (such as the third frequency resource) including PUCCH transmission. Seen as the maximum frequency resource range for transmitting PUSCH. For example, in the fourth frequency resource range, at a certain moment, the PUSCH transmission may include the RB with the lowest frequency included in the fourth frequency resource range, and at another moment, the PUSCH transmission may include the highest frequency included in the fourth frequency resource range. In other words, PUSCH transmission can be flexibly distributed in the fourth frequency resource range including PUSCH transmission, and the maximum frequency resource range used for PUSCH transmission is the frequency resource range corresponding to the fourth frequency resource.

It should be noted that, in this embodiment of the present application, the maximum frequency resource transmission range (that is, the fourth frequency resource or the fourth frequency resource range) corresponding to the PUSCH may be the frequency range corresponding to the system uplink carrier notified by the first device, Either the frequency range corresponding to the uplink channel bandwidth configured by the first device for the second device, or the frequency range corresponding to the uplink initial BWP bandwidth configured by the first device for the second type terminal device, or it can be understood The fourth frequency resource can be 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 of terminal device any of the. The second type of terminal device is a terminal device with different capabilities from the first type of terminal device, for example, a terminal device with different bandwidth capabilities. Since the second device can determine to access the first device, the system carrier uplink bandwidth information sent by the first device through broadcast information can be received by the second device, and can also be received by the first device as the second device. The upstream initial BWP bandwidth configured by the type of terminal equipment (for example, determining the upstream initial BWP corresponding to the second type of terminal equipment by receiving SIB1).

It should be understood that in some specific embodiments, when the first device can directly determine the frequency resource for transmitting PUCCH, this step is an optional step, that is, the first device can directly determine the frequency resource for transmitting PUCCH, without the need for determining a third frequency resource, and further determining a frequency resource range of the frequency resource for transmitting the PUCCH, the frequency resource range of the frequency resource for transmitting the PUCCH 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.

S802, the first device sends indication information to the second device.

The first device sends indication information to the second device, where the indication information includes second indication information and/or third indication information.

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

Exemplarily, when the first device determines the third frequency resource, the first device sends the second indication information, where the second information is used to indicate the third frequency resource, that is, the frequency including the PUCCH transmission resource.

In a possible implementation manner, taking the third frequency resource corresponding to the BWP as an example, the second indication information may correspond to the configuration information of the BWP. Optionally, the second indication information is used to indicate the third frequency resource, and may indicate at least one of the following for the second indication information: the frequency resource location of the third frequency resource, the frequency resource size of the third frequency resource, The PUCCH transmission configuration information included in the third frequency resource.

The first device sends third indication information, where the third indication information is used to indicate the fourth frequency resource, that is, the frequency resource including the PUSCH transmission.

In a possible implementation manner, taking the fourth frequency resource corresponding to the BWP as an example, the third indication information may correspond to the configuration information of the BWP. Optionally, the third indication information is used to indicate the fourth frequency resource, and may indicate at least one of the following for the third indication information: the frequency resource position of the fourth frequency resource, the frequency resource size of the fourth frequency resource, The PUSCH transmission configuration information included in the fourth frequency resource.

It can be understood that by indicating the third frequency resource and the fourth frequency resource respectively by the second indication information and the third indication information, the maximum frequency resource range including PUCCH transmission and the maximum frequency resource range including PUSCH transmission can be realized. In this way, it is possible to optimize the design of PUCCH transmission and PUSCH transmission respectively. For example, considering the impact of the bandwidth capability of the first type of terminal equipment on PUCCH frequency hopping transmission, including the maximum frequency resource range of PUCCH transmission is not greater than the first Bandwidth capability of the type of end device. On the other hand, configuring the maximum frequency resource range used for PUSCH transmission that is different from the third frequency resource range can ensure flexible scheduling of PUSCH. For the impact of the bandwidth capability of the first type of terminal equipment on the PUSCH transmission performance, it is only necessary to ensure that The PUSCH transmission resource scheduled each time does not exceed the bandwidth capability of the first type of terminal equipment, but the frequency resource location of the scheduled PUSCH can be flexibly scheduled within a fourth frequency resource range that is different from the third frequency resource, thereby ensuring the PUSCH frequency. Select Scheduling Gain.

Considering that in the disconnected state, the transmission of PUCCH is mainly for HARQ-ACK feedback of Message 4 or Message B, so the maximum frequency resource range used for PUCCH transmission (that is, the third frequency resource or the resource range of the third frequency resource) It can be sent through Message 4 or Message B in the random access process. Specifically, it can be carried by the PDCCH of the scheduled Message 4 or Message B, or it can be carried by the PDSCH including Message 4 or Message B.

In a possible implementation manner, the first device may send the indication information for indicating the third frequency resource to the second device through one or both of the Message 4 information and the Message B information.

In a possible implementation manner, in a possible implementation manner, the first device may indicate the third frequency resource to the second device by means of broadcasting information notification. For the introduction of the specific broadcast information notification manner, reference may be made to the description in S602, which is not repeated here for brevity.

In a possible implementation manner, the first device may indicate the first maximum frequency resource range to the second device through RRC dedicated signaling. For the introduction of the specific RRC dedicated signaling, reference may be made to the description in S602, which is not repeated here for brevity.

In a possible implementation manner, the second information may directly indicate the fourth frequency resource.

In a possible implementation manner, the second information does not directly indicate the fourth frequency resource, but may indicate the PUSCH scheduling resource, and the PUSCH scheduling resource may be associated with the fourth frequency resource.

It should be noted that, in this embodiment of the present application, the first information and the second information may be carried in system broadcast signaling, RRC dedicated signaling, physical layer control signaling, or media access control (medium access control, MAC) signaling In the order, the notification methods of the first information and the second information may be the same or different.

In this embodiment of the present application, the first device may configure the maximum frequency resource range for PUCCH transmission (or it may be understood that the first device configures the third frequency resource), for example, configures the third frequency resource through the second indication information, and is used for The maximum frequency resource range for PUSCH transmission may be directly implemented by scheduling PUSCH transmission without additional definition, that is, the maximum frequency resource range for PUSCH transmission may be implicitly determined by scheduling the position of PUSCH transmission. The advantage of this implementation is that PUSCH transmission can be achieved through data scheduling. Even if the bandwidth capability of the second device is limited, as long as each data scheduling is performed, the scheduled PUSCH transmission bandwidth is guaranteed to be no greater than the bandwidth capability of the second device. Yes, and PUSCH frequency hopping can also be implemented through scheduling. However, PUCCH transmission is different, because considering multi-user multiplexing, PUCCH transmission can be flexibly and dynamically scheduled unlike PUSCH transmission, and a range of frequency resources needs to be considered to support PUCCH transmission frequency hopping. Based on this, the first device can only configure PUCCH The maximum frequency range for transmission can not only ensure the data transmission performance of the second device, but also does not increase the overhead of indicating the maximum frequency resource range for excessive data transmission.

S803, the second device determines a third frequency resource.

Exemplarily, the second device may directly determine the frequency resource for transmitting the PUCCH. The frequency resource used for PUCCH transmission 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 physical uplink shared channel transmission. Frequency resource of PUSCH. Optionally, the frequency resource range of the third frequency resource is smaller than the frequency resource range of the fourth frequency resource.

For example, the second device may determine the third frequency resource. When the second device determines the third frequency resource, the second device may 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 for PUCCH transmission (or it can be understood that the first device configures the third frequency resource), for example, configure the third frequency resource through the second indication information, and the maximum frequency resource for PUSCH transmission The frequency resource range can be directly implemented by scheduling PUSCH transmission without additional definition, that is, the maximum frequency resource range used for PUSCH transmission can be implicitly determined by scheduling the position of PUSCH transmission. The advantage of this implementation is that PUSCH transmission can be achieved through data scheduling. Even if the bandwidth capability of the second device is limited, as long as each data scheduling is performed, the scheduled PUSCH transmission bandwidth is guaranteed to be no greater than the bandwidth capability of the second device. Yes, and PUSCH frequency hopping can also be implemented through scheduling. However, PUCCH transmission is different, because considering multi-user multiplexing, PUCCH transmission is not as flexible and dynamic as PUSCH transmission, and a range of frequency resources needs to be considered to support frequency hopping of PUCCH transmission. Based on this, the second device can The maximum frequency range of PUCCH transmission configured by the device, determine the frequency resource range of PUCCH transmission, and determine the frequency resource corresponding to the fourth frequency resource according to the relationship between the scheduled PUSCH transmission resource and the maximum frequency resource range used for PUSCH transmission In this way, the data transmission performance of the second device can be guaranteed, and the overhead of the indication of the maximum frequency resource range of the data transmission is not increased too much.

Exemplarily, the second device may further directly determine the frequency resource for transmitting the PUCCH according to the second indication information from the first device.

In a possible implementation manner, the maximum frequency resource range (ie, the third frequency resource) used for PUCCH transmission may be defined as the uplink initial BWP corresponding to the second device.

In a possible implementation manner, the transmission range of the maximum frequency resource corresponding to the random access preamble resource is larger than the third frequency resource or larger than the frequency resource range of the third frequency resource.

The maximum frequency resource range corresponding to the random access preamble resource sent by the second device may be the same as the maximum frequency resource range used for PUSCH transmission (that is, the frequency resource range corresponding to the fourth frequency resource) and the maximum frequency resource range used for PUCCH transmission. The ranges (that is, the frequency resource ranges corresponding to the third frequency resources) are all different. At present, the transmission bandwidth corresponding to each random access preamble resource sequence in the NR system does not exceed 20MHz, that is to say, the second device can directly use the existing random access preamble resources to achieve initial access, although all frequency division complexes are considered. Using the RACH opportunity (FDMed RACH occasion, FDMed RO) frequency resource, the frequency resource range will exceed the transmission bandwidth of the second device, but for each random access preamble resource transmission, its transmission bandwidth is within the bandwidth capability of the second device. In addition, for PUSCH transmission, as described above, transmission within a larger frequency resource range can be achieved by means of 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. In other words, it is necessary to consider the definition of the frequency resource range. Therefore, the configuration of the corresponding maximum frequency resource range can be independently considered for each channel to ensure the data transmission performance of each channel.

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

In a possible implementation manner, in this embodiment of the present application, the maximum frequency resource range corresponding to the random access preamble resource corresponding to the first type terminal may 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 still different information, but indicate the same Scope.

In this embodiment of the present application, by configuring the maximum frequency resource range corresponding to the random access preamble resource corresponding to the first type terminal device, the third frequency resource including PUCCH transmission, and the fourth frequency resource including PUSCH transmission, the distribution configuration for Different channels are designed and optimized respectively according to the channel characteristics, so as to meet the transmission requirements of each channel of the first type terminal equipment, especially the first type terminal equipment with low bandwidth capability.

FIG. 11 is another schematic diagram of a frequency resource range applicable to an embodiment of the present application. As shown in the figure, for the second device, for example, in the initial access phase, the maximum frequency resource range used for random access preamble resource transmission, the maximum frequency resource range used for PUCCH transmission, and the maximum frequency resource range used for PUSCH transmission The sizes corresponding to the maximum frequency resource ranges of , may be different from each other, and further, one of the maximum frequency resources may be used as the uplink initial BWP corresponding to the second device.

S804, the second device transmits the PUCCH to the first device in the third frequency resource.

The second device transmits the PUCCH to the first device within the third frequency resource.

Exemplarily, after the second device determines the frequency resource for transmitting the PUCCH, the second device transmits the PUCCH in the third frequency resource. Correspondingly, the first device receives the PUCCH from the second device in the third frequency resource.

In this embodiment of the present application, the maximum frequency resource range corresponding to the random access preamble resource sent by the second device may be different from the maximum frequency resource range used for PUSCH transmission and the maximum frequency resource range used for PUCCH transmission. For the second device, for example, in the initial access phase, 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 The corresponding sizes may be different from each other. In a possible implementation manner, one of the maximum frequency resources may be used as the uplink initial BWP corresponding to the second device.

It should be noted that, in this embodiment of the present application, the first device further configures a maximum frequency resource range for PUCCH transmission and a maximum frequency resource range for PUSCH transmission corresponding to the second type of terminal device. For example, in the random access process, the first device may configure the maximum frequency resource range for PUCCH transmission corresponding to the uplink initial BWP corresponding to the second type terminal device and the maximum frequency resource range for PUSCH transmission, that is, for the second type terminal device, The maximum frequency resource corresponding to PUCCH transmission and the maximum frequency resource corresponding to PUSCH transmission may 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 may be the same information. Optionally, the maximum frequency resource used for transmitting PUCCH corresponding to the second type terminal equipment (also the maximum frequency resource used for transmitting PUSCH by the second type terminal equipment) may be used as the fourth frequency resource in this embodiment of the present application, that is, the first frequency resource. The maximum frequency resource used for transmitting PUSCH corresponding to one type of terminal equipment. Optionally, the configuration information used by the first device to configure the maximum frequency resource range of PUCCH transmission and the maximum frequency resource range of PUSCH transmission corresponding to the second type terminal device may be the same as the second indication information, the third indication information, The fourth indication information is all different.

In this embodiment of the present application, the frequency resource consists of N continuous/non-consecutive PRBs/RBs, where N is a positive integer. Exemplarily, the frequency domain resource consists of N consecutive PRBs/RBs. For example, the frequency resource may be BWP.

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