Description

Wireless access method and device

Technical Field

The present application relates to the field of communications, and, more particularly, to methods and apparatus for wireless access.

Background

In the communication process, as the requirement of the service under the application scene corresponding to the machine type terminal equipment on the data transmission rate is not high, the implementation specification can be reduced, and the implementation cost is further reduced; on the other hand, the reduction of the implementation cost of the machine terminal equipment is also helpful for expanding the market of the machine terminal equipment and promoting the development of the internet of things market.

However, in some scenarios, such as a New Radio (NR) system, in an initial access phase, there is no interaction between a base station and a corresponding cell, so that the base station cannot acquire the type of a terminal device, such as a machine type terminal device, and cannot determine the bandwidth capability of the terminal device; meanwhile, since the base station cannot identify each machine terminal device, it is impossible to individually configure a data transmission frequency resource for each machine terminal device through a dedicated signaling of the terminal device, which may cause an excessive load on the data transmission frequency resource in the non-connected state; in addition, the uplink initial bandwidth portion may be used for a physical uplink shared channel for transmitting information 3 and a physical uplink control channel for transmitting hybrid automatic repeat request feedback in the random access process, where the hybrid automatic repeat request feedback is feedback for information 4 in the initial access process, and in addition, physical random access channel resources in the initial access process must be transmitted in the uplink initial bandwidth portion. Furthermore, the terminal device may further ensure data transmission performance with the base station during the connection process through the physical uplink control channel frequency hopping and the physical uplink shared channel frequency hopping, where a frequency range of the physical uplink control channel frequency hopping and a frequency range of the physical uplink shared channel frequency hopping also need to be ensured in the uplink initial bandwidth portion. It is therefore necessary for the NR terminal device to define a frequency range that includes the above-mentioned data transmission resources as well as frequency hopping resources, so that it is guaranteed that a data transmission connection is established with the base station.

Detailed Description

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

The New Radio (NR) of the Fifth Generation (5G) Mobile Communication technology is a global 5G standard designed based on a New air interface of Orthogonal Frequency Division Multiplexing (OFDM), which is also a very important cellular Mobile technology base of the next Generation, and the services of the 5G technology are very diverse and can be oriented to Enhanced Mobile Broadband (eMBB) services, Ultra-reliable Low-Latency Communication (URLLC) services, and mass Machine Communication (mtc) services, wherein the mtc services may be Industrial Wireless Sensor Network (sn) services, Video monitoring (Video) services, and wearable services.

Machine type terminal equipment often has higher requirements on cost and power consumption. For example, machine type terminal equipment is generally realized at low cost, because the service under the application scene corresponding to the machine type terminal equipment does not have high requirement on data transmission rate, for example, the data transmission rate carried by a sensor under the IWSN is not more than 2Mbps, which is enough to satisfy the IWSN service, the data transmission rate carried by an economical video monitoring camera is generally 2-4 Mbps, the downlink peak rate of the terminal equipment under the wearable service, such as a smart watch, does not exceed 150Mbps, the uplink peak rate does not exceed 50Mbps, which is much lower than the peak rate of NR legacy terminal equipment (such as NR eMBB terminal equipment), based on which, the machine type terminal equipment can reduce the realization specification relative to the NR legacy terminal equipment, thereby reducing the realization cost; on the other hand, the reduction of the implementation cost of the machine terminal equipment is also helpful for expanding the market of the machine terminal equipment and promoting the development of the internet of things market. Currently, 3GPP initiated research (reference: RP-193238) on low-power terminal equipment (NR reduced capability, NR red cap) under NR system, aiming at designing a terminal equipment meeting performance requirements of the internet of things market and having low cost/implementation complexity for increasing the application of NR system in the internet of things market aiming at the increasing internet of things market, such as the above-mentioned IWSN, video monitoring and wearable services. For convenience of description, in the following section, NR red map UE is taken as an example for illustration.

One way to reduce the cost of the terminal device is to reduce the channel bandwidth of the terminal device, or it can also be understood as reducing the bandwidth capability of the terminal device, i.e. the bandwidth capability of the NR red map UE may be much smaller than the bandwidth capability of the NR legacy terminal device. Currently, the bandwidth capability that an NR Legacy terminal device, for example, a terminal device of release Rel-15/release Rel-16, must have is 100MHz, and the bandwidth capability of an NR reload UE may be only 20MHz from the viewpoint of being able to receive an initial access signal transmitted by an NR base station and then access the NR system, and under some configurations of the NR system, the bandwidth capability of the NR reload UE may be further reduced, for example, to 5MHz or 10MHz, and at this time, the NR reload UE may also access the NR system. A bandwidth capability of no greater than 20MHz may greatly reduce the cost of a red cap UE relative to a bandwidth capability of 100 MHz.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: a fifth generation (5G) system or a New Radio (NR), a Long Term Evolution (LTE) system, a Frequency Division Duplex (FDD) system, a Time Division Duplex (TDD) system, a Universal Mobile Telecommunications System (UMTS), and the like. The technical solution of the embodiment of the present application may also be applied to device-to-device (D2D) communication and the like.

For the understanding of the embodiments of the present application, a communication system suitable for the embodiments of the present application will be described in detail with reference to fig. 1 and 2.

Fig. 1 is a diagram of a wireless communication system 100 suitable for use in embodiments of the present application. As shown, 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 further include at least one terminal device, such as the terminal devices 121 to 123 shown in fig. 1. The network equipment and the terminal equipment can be both provided with a plurality of antennas, and the network equipment and the terminal equipment can communicate by using a multi-antenna technology.

When the network device and the terminal device communicate with each other, the network device may manage one or more cells, and each cell may provide a service for at least one terminal device. In a possible implementation manner, the network device 111 and the terminal devices 121 to 123 form a single-cell communication system, and without loss of generality, a cell is denoted as cell # 1. Network device 111 may be a network device in cell #1, or network device 111 may serve a terminal device (e.g., terminal device 121) in cell # 1.

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

Fig. 2 is another schematic diagram of a wireless communication system 200 suitable for use in embodiments of the present application. As shown in the figure, the technical solution of the embodiment of the present application may also be applied to D2D communication. The wireless communication system 200 includes a plurality of terminal apparatuses, such as the terminal apparatus 201 to the terminal apparatus 203 in fig. 2. The terminal 201 to the terminal 203 can directly communicate with each other. For example, terminal device 201 and terminal device 202 may transmit data to terminal device 203 separately or simultaneously.

It should be understood that fig. 1 and 2 are only exemplary, and the present application is not limited thereto. For example, the embodiments of the present application may also be applied to a random access scenario (e.g., a 5G NR random access procedure).

It should also be understood that the network device in the wireless communication system may be any device having a wireless transceiving function. Such devices include, but are not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (Node B, NB), Base Station Controller (BSC), Base Transceiver Station (BTS), Home Base Station (e.g., Home evolved NodeB, or Home Node B, HNB), BaseBand Unit (Base band Unit, BBU), Access Point (AP) in Wireless Fidelity (WIFI) system, etc., and may also be 5G, such as NR, gbb in system, or TRP, transmission Point (TRP or TP), one or a group of antennas (including multiple antennas, NB, or a transmission panel) of a Base Station in 5G system, such as a baseband unit (BBU), or a Distributed Unit (DU), etc.

In some deployments, the gNB may include a Centralized Unit (CU) and a DU. The gNB may further include an Active Antenna Unit (AAU). The CU implements part of the function of the gNB and the DU implements part of the function of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, and implementing functions of a Radio Resource Control (RRC) layer and a Packet Data Convergence Protocol (PDCP) layer. The DU is responsible for processing a physical layer protocol and a real-time service, and implements functions of a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, and a Physical (PHY) layer. The AAU implements part of the physical layer processing functions, radio frequency processing and active antenna related functions. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as the RRC layer signaling, may also be considered to be transmitted by the DU or by the DU + AAU under this architecture. It is to be understood that the network device may be a device comprising one or more of a CU node, a DU node, an AAU node. In addition, the CU may be divided into network devices in an access network (RAN), or may be divided into network devices in a Core Network (CN), which is not limited in this application.

It should also be understood that terminal equipment in the wireless communication system may also be referred to as User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminal device in the embodiment of the present application may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like. The embodiments of the present application do not limit the application scenarios.

To facilitate understanding of the embodiments of the present application, a brief description of several terms referred to in the present application will be given below.

1. Physical uplink control channel

A Physical Uplink Control CHannel (PUCCH) is used to carry Uplink Control information, and compared with LTE, an NR PUCCH supports 5 different formats, and can be divided into a short format and a long format according to the number of symbols occupied in a time domain, where the short format occupies 1-2 symbols and can carry 1-2 bits (bit) information, and the long format occupies 4-14 symbols and can carry information greater than 2 bits. The purpose of introducing the short-format PUCCH by the NR is to shorten the HARQ-ACK (Hybrid Automatic Repeat-Request Acknowledgement) feedback delay, and the long format still allows for a long duration to ensure coverage.

In NR, all PUCCHs of 2 or more symbols are configurable hopping, including intra-slot and inter-slot hopping, considering flexibility of system configuration. The number of symbols in the first hop (hop) during hopping is such that the remaining symbols are in the second hop.

PUCCH format 0134 uses low peak-to-average power ratio (low-PAPR) sequences, which can reduce the PAPR for uplink transmission. The low-PAPR sequence is generated by cyclic shift on the basis of a base sequence, which is divided into two cases according to the difference in sequence length.

2. Physical uplink shared channel

A Physical Uplink Shared Channel (PUSCH) is used to carry data from the transport Channel USCH. By shared is meant that the same physical channel may be used by multiple users in a time-shared manner, or that the channel has a short duration.

3. Controlling resource collections

A Control-Resource Set (CORESET) mainly indicates the number of symbols (time domain) occupied by a physical downlink Control channel and the number of RBs (frequency domain), that is, the CORESET indicates the frequency domain Resource including the PDCCH. The CORESET comprises a plurality of PRBs, the Minimum number of the PRBs is 6 time domains, the symbol number is 1-3, each cell can be configured with a plurality of CORESETs (0-11), wherein the COREST0 can be used for Remaining Minimum System Information (RMSI) (which can also be used for scheduling of a System Information Block Type 1 (SIB 1).

4. Physical downlink control channel

A Physical Downlink Control Channel (PDCCH) carries scheduling and other Control information, specifically including transport format, resource allocation, uplink scheduling grant, power Control, uplink retransmission information, and the like. The PDCCH channel is a set of physical resource elements, which carries uplink and downlink control information, and the PDCCH carrying information distinguishes common control information (common search space) and dedicated control information (dedicated search space) according to their different scopes.

5. Master information block

When a network side device is powered on, a Master Information Block (MIB) message is sent first, and then a series of System Information Block (SIB) messages are sent. The MIB message carries the most basic information, which relates to decoding of the physical downlink shared channel, and the UE can continue to decode data in the physical downlink shared channel, including decoding system message block information, by using parameters in the MIB only when decoding the MIB first.

6. Radio resource control state

RRC state, the terminal device has 3 RRC states: RRC connected state, RRC idle state, and RRC inactive state.

The RRC connected (connected) state (or, may also be referred to simply as connected state herein, "connected state" and "RRC connected state" are the same concept and the two designations may be interchanged): the terminal device establishes RRC connection with the network and can perform data transmission.

Herein, "idle state" and "RRC idle state" are the same concept, and the two designations may be interchanged): the terminal device does not establish an RRC connection with the network and the base station does not store the context of the terminal device. If the terminal device needs to enter the RRC connected state from the RRC idle state, an RRC connection establishment procedure needs to be initiated.

Herein, "deactivated dynamic," "deactivated," "inactive," "RRC inactive," or "RRC deactivated," etc. are the same concept, and these designations may be interchanged): the terminal device has previously entered the RRC connected state at the anchor base station, which then releases the RRC connection, but the anchor base station maintains the context of the terminal device. If the terminal device needs to enter the RRC connected state again from the RRC inactive state, an RRC connection recovery procedure (alternatively referred to as an RRC connection re-establishment procedure) needs to be initiated at the currently camped base station. 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 different base stations. Compared with the RRC establishment process, the RRC recovery process has shorter time delay and smaller signaling overhead. However, the base station needs to store the context of the terminal device, which occupies the storage overhead of the base station.

7. System message block

A System Information Block (SIB) is System Information broadcast by a base station and is divided into a plurality of types, so that it can be transmitted using different frequencies. There are 19 types of SIBs in total, and the scheduling information of the SIB is carried by the MIB or SB.

In order to ensure data transmission with the NR base station, the terminal device needs to establish a connection with the NR base station through a random access procedure, so that the NR base station can identify the terminal device and complete subsequent data transmission. Taking initial access as an example, in an idle state (idle state), by receiving a Synchronization Signal Block (SSB) sent by an NR base station, an NR Legacy terminal device may implement time-frequency synchronization with the NR base station and obtain cell initial access configuration information corresponding to the NR base station, that is, system information block 1 (SIB 1) information, and configure a resource used by the terminal device to initiate random access and a continuous bandwidth resource including the random access resource in an SIB1, where the continuous bandwidth resource is defined as an uplink initial bandwidth part (BWP) in a current protocol. The uplink initial BWP may be used in a Physical Uplink Shared Channel (PUSCH) for transmitting information 3(message 3, Msg3) in a random access procedure, a Physical Uplink Control Channel (PUCCH) for transmitting information a (Msg a) and for transmitting hybrid automatic repeat request (HARQ) feedback in the random access procedure, where the HARQ feedback is feedback for information 4(message 4, Msg 4) in the random access procedure or for information B (message B, Msg B) in the random access procedure, and besides, resources of the Physical Random Access Channel (PRACH) in the random access procedure must be transmitted in the uplink initial BWP. Further, the terminal device may also ensure 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, where a frequency range of the PUCCH frequency hopping and a frequency range of the PUSCH frequency hopping also need to be ensured within the uplink initial BWP. It is therefore necessary for the NR terminal device to define a frequency range that includes the above-mentioned data transmission resources as well as frequency hopping resources, so that it is guaranteed that a data transmission connection is established with the base station.

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

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

In conjunction with the above description, for NR red map UEs, in order to guarantee data transmission with the base station, it is also necessary to consider designing its uplink initial BWP for the red map UEs.

Fig. 3 is an architecture diagram of a random access phase system data transmission. In the prior art, first, in the random access phase, the frequency resource configuration of the uplink initial BWP is included in SIB1 information, and before the terminal device receives SIB1 information, data transmission between the terminal device and the base station is as shown in fig. 3, it can be observed that before the terminal device receives SIB1 information, the terminal device does not transmit uplink information, that is, there is no interaction between cells corresponding to NR base stations, and therefore, the NR base station (or network side device) cannot acquire the type of the terminal device, that is, it is not determined whether the terminal device receiving SIB1 information is a terminal device with bandwidth capability of 100MHz or a terminal device with bandwidth capability of not greater than 20MHz (for example, NR RedCap terminal device). This causes the following problems in the prior art:

(1) the uplink initial BWP bandwidth configured by the network device exceeds the bandwidth capability of the NR red map UE, resulting in no access for the NR red map terminal device.

For example, the uplink initial BWP includes PRACH resources, and according to the current protocol, the total PRACH resource bandwidth configured by the network device may exceed 20 MHz. On the other hand, in the NR system, there is a correspondence between the SSB and the PRACH resource (such as a preamble), the UE may select a corresponding preamble to initiate random access according to the detected SSB and the correspondence between the SSB and the preamble, the network device may determine, through the received preamble, an SSB beam direction detected by the UE that initiates the preamble, and send downlink data to the UE through the SSB beam direction corresponding to the preamble before establishing Radio Resource Control (RRC) connection with the UE, so that downlink data transmission performance may be ensured. However, since the total PRACH resource bandwidth configured by the network device may exceed 20MHz, the NR red beacon UE may not select the PRACH resource corresponding to the optimal SSB beam direction, which further affects data transmission performance of the red beacon UE, and even causes the red beacon UE to be unable to access.

(2) And limiting the uplink initial BWP bandwidth corresponding to the NR Legacy UE, and influencing the initial access performance of the NR Legacy UE.

The network device may configure the uplink initial BWP bandwidth size to a value not greater than the NR reccap UE bandwidth capability when configuring the uplink initial BWP bandwidth in consideration of the NR reccap UE that may exist in the system, so as to ensure the access of the reccap UE, but this may limit the performance of Legacy UE access. For another example, configuring the uplink initial BWP bandwidth according to the NR red map UE also affects the capacity of legacy UE access. For example, for NR Legacy UEs, the initial uplink BWP may be configured to 100MHz at maximum, whereas if NR red cp UEs and NR Legacy UEs are considered to share the initial uplink BWP, the bandwidth of the initial uplink BWP can only be configured to 20MHz, and the bandwidth reduction of the initial uplink BWP may reduce the access capacity of the NR Legacy UEs.

Fig. 4 is a schematic diagram of a resource load of a data transmission frequency resource. The first type terminal device may be a low-cost and low-bandwidth terminal device, such as an NR reccap UE, and the second type terminal device may be a Legacy terminal device (NR Legacy UE, such as an NR eMBB UE). As shown, the data transmission frequency resource for the non-connected state cannot exceed the bandwidth capability of the first type terminal device due to the limitation of the bandwidth capability of the first type terminal device, so that 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 in the non-connected state, such as the initial access phase. In consideration of the above, in a non-connected state, for example, in an initial access phase, the network device cannot identify each first type terminal device, and therefore, a data transmission frequency resource cannot be configured for each first type terminal device individually through a dedicated signaling of the terminal device, which may result in that the first type terminal devices that aim to establish an RRC connection with the network device in the non-connected state are concentrated in a frequency range, for example, 20 MHz. Consider that in the unconnected state, the 20MHz band would include transmissions for the following channels: preamble transmission, Msg3 transmission in the random access process, HARQ-ACK transmission for Msg4, and the like, and for a connected terminal device, the data transmission with the network device is completed by falling back to a corresponding data transmission frequency resource in a non-connected state under certain conditions. This results in an excessive load on the data transmission frequency resources in the unconnected state, especially when considering the number of connections of the first type of terminal equipment is large, which results in a further increased load on the data transmission frequency resources. For the second type terminal device, the above problem does not exist, because the requisite bandwidth capability of the second type terminal device is 100MHz, so that the network device can configure a data transmission frequency resource with a relatively large frequency resource range.

The distinction between the first terminal device and the second terminal device comprises at least one of:

1. the bandwidth capabilities are different. For example, the second type terminal device may support data transmission using 100MHz frequency domain resources and network devices on one carrier at maximum, and the first type terminal device may support data transmission using 20MHz, 10MHz, or 5MHz frequency domain resources and network devices on one carrier at maximum.

2. The number of the transmitting and receiving antennas is different. For example, the antenna configuration supported by the second type terminal device at the minimum is 4-transmission and 2-reception, that is, under the minimum antenna configuration, 4 receiving antennas are used to receive downlink data, and 2 transmitting antennas are used to transmit uplink data; and the maximum supported antenna configuration of the first type terminal device is lower than 4 rd-to-2 rd-to, for example, the first type terminal device UE only supports 2 rd-to-1 rd-to, or may also support 1 rd-to-1 rd-to, or may also support 2 rd-to-2 rd-to.

3. The maximum uplink transmission power is different. For example, the maximum uplink transmit power of the second type terminal device may be 23dBm or 26dBm, and the maximum uplink transmit power of the first type terminal device may be one of 4dBm to 20 dBm.

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

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

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

7. The second type terminal device has a different processing capability than the first type terminal device. The processing power of the first type of terminal device is lower than that of the second type of terminal device. For example, the first type terminal device and the second type terminal device have different processing time capabilities for data. For example, the minimum time delay between the reception of the downlink data and the transmission of the feedback to the downlink data by the second type terminal device is smaller than the minimum time delay between the reception of the downlink data and the transmission of the feedback to the downlink data by the first type terminal device. The minimum time delay between the sending of the uplink data and the receiving of the feedback of the uplink data by the second type terminal equipment is smaller than the minimum time delay between the sending of the uplink data and the receiving of the feedback of the uplink data by the first type terminal equipment. As another example, the maximum Transport Block Size (TBS) that can be processed by the first type of terminal device is smaller than the TBS that can be processed by the second type of terminal device. For another example, the maximum downlink modulation order (e.g., 64QAM) that can be processed by the terminal device of the first type is smaller than the maximum downlink modulation order (e.g., 256QAM) that can be processed by the terminal device of the second type, and/or the maximum uplink modulation order (e.g., 64QAM or 16QAM) that can be processed by the terminal device of the first type is smaller than the maximum uplink modulation order (e.g., 256QAM or 64QAM) that can be processed by the terminal device of the second type. For another example, the number of hybrid Automatic Repeat requests (HARQ) supported by the first type terminal device is smaller than the number of HARQ supported by the second type terminal device.

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

In the embodiment of the present application, the first type terminal device takes an NR red map terminal device as an example, and the second type terminal device takes an NR Legacy terminal device as an example.

Fig. 5 shows a system architecture diagram for wireless access suitable for embodiments of the present application. As shown in the figure, the network device and the terminal device of the present application are connected by an air interface.

In this application, terminal devices, including devices that provide voice and/or data connectivity to a user, may include, for example, handheld devices having wireless connection capabilities or processing devices connected to wireless modems. More specifically, the UE may be, for example, an LTE terminal, a 5G terminal, or a UE.

Network equipment, including Access Network (AN) equipment, such as a base station (e.g., AN access point), may refer to equipment in AN access network that communicates over the air with wireless terminal equipment over one or more cells. Optionally, for example, it may be: LTE eNB/HeNB/Relay/Femto/Pico, 5G base station.

Description of terminal device: in this application, the terminal device may further include a Relay, and both the terminal device and the network device that can perform data communication may be regarded as the terminal device.

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

It should be noted that although a low-power, low-cost, or low-complexity terminal device is exemplified in the present application, the illustrated embodiments are also applicable to other types of terminal devices, such as NR Rel-17 or beyond. For convenience of description, the present application will be described taking NR red map UE as an example.

It should be noted that, in the present application, the data transmission frequency resource, or the maximum frequency resource for PUSCH transmission, the maximum frequency resource for PUCCH transmission, and the maximum frequency resource for NR red map UE preamble transmission are all composed of consecutive Resource Blocks (RBs).

Various embodiments provided herein will be described in detail below with reference to the accompanying drawings.

Fig. 6 is a schematic flow chart of a method for wireless access suitable for use in an embodiment of the present application. The method 600 may include the following steps.

In the following embodiments, for differentiation and without loss of generality, the network device is represented by a first device and the first type of terminal device, e.g. an NR red map UE, is represented by a second device.

It should be understood that the first device may have other forms, for example, the first device and the second device may both be a first type terminal device, or the first device may also be a second type terminal device (NR Legacy UE, for example, NR eMBB UE), and the second device may be the first type terminal device. And are not limited herein.

It should be understood that in the present application, the main difference between the first type of terminal device and the second type of terminal device is the difference in bandwidth capability, however, in the implementation process, the difference between the first type of terminal device and the second type of terminal device is not limited to the difference in bandwidth capability, i.e. the difference in bandwidth capability is not an indispensable distinguishing feature.

S601 the first device determines a first frequency resource.

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

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

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

It should be noted that the second frequency resource is used for transmitting uplink data, and preferably, the uplink data herein may include uplink data in a random access process, such as random access preamble sequence preamble, Msg a, Msg3, and HARQ-ACK transmission for random access Msg2 or Msg4, where the HARQ-ACK transmission is carried in PUCCH. In a possible implementation manner, the second frequency resource may also be used for uplink data transmitted by the first type terminal device 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 device can implement service load balancing, and is particularly beneficial to large-connection first type terminal devices.

Furthermore, defining M second frequency resources among the N second frequency resources includes PUCCH transmission (where M is smaller than N), which may reduce the performance impact of PUCCH transmission, especially PUCCH frequency hopping transmission, on PUSCH transmission of other terminal devices in the system, for example, the performance impact on PUSCH transmission of legacy UEs or wideband UEs (e.g., channel bandwidth capability of 100MHz) in the system; on the other hand, considering that the PUCCH can support multi-user multiplexing transmission, it is not necessary to include PUCCH transmission in each second frequency resource, which may also reduce PUCCH overhead while ensuring multi-user HARQ-ACK transmission performance.

In one possible implementation manner, only 1 frequency resource of the N second frequency resources includes a frequency resource used for PUCCH transmission, which may further reduce transmission overhead of PUCCH. Further, in a possible implementation manner, when only 1 frequency resource of the N second frequency resources includes a frequency resource used for PUCCH transmission, the first frequency resource is a frequency resource including a highest frequency or a lowest frequency among the N second frequency resources. Taking N-3 as an example, assuming that a frequency resource range included in 1 of the 3 second frequency resources corresponds to a frequency resource range composed of a CRB with a Common Resource Block (CRB) index of p1 and a CRB with a CRB index of p2, a frequency resource range included in the other 1 second frequency resources corresponds to a frequency resource range composed of a CRB with a CRB index of p3 and a CRB with a CRB index of p4, and a frequency resource range included in the other 1 second frequency resource corresponds to a frequency resource range composed of a CRB with a CRB index of p5 and a CRB with a CRB index of p6, where p1< p2< p3< p4< p5< p6, a frequency resource including PUCCH transmission or a first frequency resource may correspond to a frequency resource with a CRB index of p1 and a frequency end point CRB index of p2, or a frequency resource including a PUCCH transmission start point or a frequency resource corresponding to a CRB index of p 8536 and a frequency index of CRB of p 857 . Here, CRB is a resource block determined with respect to system carrier point a, and system carrier point a may correspond to a subcarrier with a lowest frequency included in a resource block with a lowest frequency included in the system carrier, or to a frequency-domain resource unit with a lowest frequency included in the system carrier bandwidth, where the frequency-domain resource unit with a lowest frequency includes the subcarrier with a lowest frequency corresponding to the system carrier bandwidth. Or in this application, the highest frequency or the lowest frequency may also be represented by a frequency corresponding to a subcarrier included in the second frequency resource, and in the N second frequency resources, the second frequency resource including the lowest frequency subcarrier may be understood as a frequency resource including the lowest frequency in the N second frequency resources, and the second frequency resource including the highest frequency subcarrier may be understood as a frequency resource including the highest frequency in the N second frequency resources. Alternatively, in the present 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. Or may be otherwise used without specific limitation. Since the PUCCH generally employs a frequency hopping manner to ensure the performance of PUCCH transmission, the first frequency resource including PUCCH transmission is limited to the frequency resource with the highest frequency or the lowest frequency among the N second frequency resources, so that the influence on the PUSCH transmission performance of other terminal devices, such as a second type terminal device, a terminal device with a large bandwidth capability (e.g., 100MHz), a Legacy terminal device, and the like, may be reduced.

In one possible implementation, 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, and is used as the first frequency resource, for example, the first frequency resource is a continuous segment of frequency resource in the specific frequency resource and includes a frequency domain resource unit with the highest frequency or a frequency domain resource unit with the lowest frequency in the specific frequency resource. The specific frequency resource may be a system uplink carrier corresponding to the first type terminal device or a system uplink carrier corresponding to the second type terminal device, and the system uplink carriers corresponding to the first type terminal device or the system uplink carriers corresponding to the second type terminal device may be the same or different. Or, the specific frequency resource may also be an uplink initial BWP corresponding to the second type terminal device, or the specific frequency resource may also be an uplink channel transmission bandwidth corresponding to the first type terminal device or an uplink channel transmission bandwidth corresponding to the second type terminal device. Since the PUCCH generally employs a frequency hopping scheme to ensure the performance of PUCCH transmission, the first frequency resource including PUCCH transmission is configured on one side of the frequency resource of the specific frequency resource, so that the influence on the data transmission rate of other terminal devices in the system, for example, the second type terminal device, can be reduced.

It should be understood that the second frequency resource herein may be not only a frequency resource for guaranteeing random access data, but also a frequency resource for transmitting other uplink data, and 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 in a broadcast information notification manner or an RRC dedicated signaling manner, which is not limited in this application. Alternatively, the first device may also indicate the first frequency resource through physical layer signaling.

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

Illustratively, the first device transmits first indication information indicating configuration information of a first frequency resource and/or information of a resource index for transmitting a PUCCH.

Specifically, in one implementation, when configuring N second frequency resources, the first device implements the first frequency resource including the transmission PUCCH by using the second frequency resource identifier. For example, the first device notifies N second frequency resources by broadcasting information, but only 1 of the N second frequency resources includes a frequency resource used for transmitting the PUCCH, and when configuring the N second frequency resources, the first device may simultaneously configure identification information corresponding to the second frequency resources, which is used to indicate whether the second frequency resources include the PUCCH resource. In one implementation, the first device may indicate which second frequency resource includes the PUCCH resource by configuring a second frequency resource index including the PUCCH resource. For example, the first device configures 4 second frequency resources, and the corresponding second frequency resource indexes are 0,1,2, and 3, in this implementation manner, the first device configures the second frequency resource index including the PUCCH resource as any one of the second frequency resource indexes 0 to 3; or the first device may directly implement indicating the second frequency resource including the PUCCH resource by configuring whether the PUCCH resource is included in the N second frequency resources. For example, the first device configures 4 second frequency resources, the frequency resource indexes are 0 to 3, and meanwhile, the first device configures PUCCH resources only for the second frequency resource with the frequency resource index of 0, and does not configure PUCCH resources for other second frequency resources. The first frequency resource can be determined by an identification of a frequency resource included in the resource configuration for transmitting the PUCCH.

In one possible implementation manner, the first device may inform the second device of the configuration information of the first frequency resource and/or the information of the resource index used for transmitting the PUCCH by means of broadcast information notification.

In an embodiment of the present application, the configuration information of the first frequency resource includes at least one of: a frequency resource location (including a bandwidth size, a frequency start position) of the first frequency resource, configuration information for PUCCH transmission within the first frequency resource, the configuration information for PUCCH transmission including at least one of: the PUCCH transmission format, the number of symbols corresponding to PUCCH transmission, the frequency resource of PUCCH transmission, and the code resource of PUCCH transmission.

In an implementation manner, the first device may directly notify the configuration information of the first frequency resource, specifically, the configuration information may be notified through system broadcast information, RRC dedicated signaling, or physical layer signaling, or may also use other manners, which is not limited specifically. In another implementation, the first device may configure N second frequency resources and indicate identification information of the second frequency resources corresponding to the first frequency resources to configure the first frequency resources. For example, the first device configures 4 second frequency resources, where the second frequency resource with the second frequency resource index of 0 is identified as the frequency resource including the PUCCH resource (the specific implementation manner is the same as that in the foregoing embodiment), the second frequency resource identified as including the PUCCH resource may be determined as the first frequency resource.

In another implementation, the first device may also notify resource index information for transmission of the PUCCH, which may correspond to frequency resource information, e.g., resource block information, for PUCCH transmission.

Specifically, for example, 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 the Location And Bandwidth for a rdcap UE included in the SIB 1. It should be understood that the broadcast information here may be information carried by a Physical Broadcast Channel (PBCH), such as information included in MIB, or may be information included in control information of scheduling system information block SIB transmission or information included in SIB information, where the control information of scheduling SIB transmission may be carried in PDCCH and the SIB information may be carried in PDSCH.

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

Specifically, the first device may configure, by RRC dedicated signaling, information of a target frequency resource and/or information of a resource index used for transmitting a PUCCH when the second device falls back to an RRC inactive state, and may be used for data transmission by the second device through the first frequency resource and the first device in an unconnected state.

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

Preferably, the first device may send the configuration information of the first frequency resource to the second device through Location And Bandwidth for a resume UE included in SIB1, or send the configuration information of the first frequency resource to the second device through other information included in SIB 1. Alternatively, the first device may transmit configuration information of the first frequency resource or resource index information of the PUCCH to the second device through control information included in the Msg2 or the Msg4 in a random access procedure.

S603 the second device determines a first frequency resource.

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

In a possible implementation manner, when the indication information is used to indicate a resource index of a transmission PUCCH, the second device needs to determine a resource block of the transmission PUCCH according to the resource index of the transmission PUCCH, and determine a first frequency resource according to the resource block of the transmission PUCCH, where the first frequency resource includes the resource block of the transmission PUCCH. Preferably, the first frequency resource includes a frequency resource having a highest frequency or a lowest frequency among the at least 2 first frequency resources.

Fig. 7 is a schematic diagram of a frequency resource for transmitting PUCCH suitable for the embodiment of the present application, and as shown in the drawing, in the embodiment, there are 2 second frequency resources, only one second frequency resource includes PUCCH transmission (corresponding to the second frequency resource #1 in the drawing), and the second frequency resource #2 does not include the frequency resource for PUCCH transmission. It should be understood that within a frequency resource including PUCCH transmission, a frequency resource for PUSCH transmission may be included in addition to a frequency resource for PUCCH transmission. In one possible implementation, among the 2 second frequency resources, 1 second frequency resource (i.e., second frequency resource #1) may correspond to the uplink initial BWP of the first type end device, e.g., the reccap end device.

Only one second frequency resource including a PUCCH resource within the at least 2 second frequency resources may reduce control channel overhead. Considering that data carried on the PUCCH can implement multi-user multiplexing through Frequency Division Multiplexing (FDM) and also can implement multi-user multiplexing through Code Division Multiplexing (CDM), in addition, in a non-connected state, data transmission carried on the PUCCH is mainly HARQ-ACK feedback for downlink data, and by combining the above two points, the PUCCH transmission resource has a smaller resource overhead relative to the PUSCH transmission resource, so that each first frequency resource does not need to include a PUCCH resource, and thus, for the first frequency resource not including the PUCCH, a certain peak rate of uplink data transmission can be ensured. Furthermore, if only one second frequency resource comprises PUCCH transmission, the data transmission performance impact for the NR Legacy UE may be smaller. This is because at least 2 second frequency resources are FDM in frequency, but there may be some overlapping frequency resources, and if each second frequency resource includes a PUCCH resource, considering that the PUCCH resource is generally smaller in bandwidth and on two sides of the second frequency resource respectively for ensuring performance, there may be multiple narrowband and discrete PUCCH resources distributed in one carrier bandwidth, which may affect the continuous resource size and Resource Block Group (RBG) allocation of uplink data transmission of the NR Legacy UE. Through the embodiment, even if at least 2 second frequency resources exist for the NR RedCap UE, only 1 second frequency resource comprises one PUCCH resource, so that the data transmission performance of the NR RedCap UE is ensured, and the influence on the data transmission performance of the NR Legacy UE is reduced.

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

The second device may exemplarily 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 second frequency resources may be associated with a transmission bandwidth for downlink system information of the second type terminal device, the larger the bandwidth, the larger the number N.

For example, the number of the second frequency resources may be associated with frequency resources for transmitting random access uplink data of the second type terminal device.

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

For example, the second device may determine the number N of the second frequency resources according to one or more of a bandwidth of the system carrier, a frequency band in which the system carrier is located, a frequency resource for transmitting random access uplink data of the second type terminal device, and a transmission bandwidth for transmitting downlink system information of the second type terminal device, which is not limited in this application. The transmission bandwidth for transmitting the downlink system information of the second-type terminal device may be a transmission bandwidth of the downlink initial BWP corresponding to the second-type terminal device, for example, a frequency domain resource corresponding to core set #0 indicated by the pdcch-ConfigSIB1 control field in the MIB.

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 location of each second frequency resource.

For example, the second device may determine the location 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 a PUCCH to the first device within the first frequency resource.

For example, after the second device determines a first frequency resource including a frequency resource used for transmitting the PUCCH, the PUCCH may be transmitted through the first frequency resource, and the first device receives data carried by the PUCCH from the second device within the first frequency resource.

It should be understood that the present embodiment is exemplified by one of the terminal devices of the first type, i.e., the second device, however, the first frequency resource may be a frequency resource suitable for the terminal device of the first type.

Fig. 8 is another schematic flow chart of a method for uplink data transmission according to an embodiment of the present application. The method 800 may include the following steps.

In the following embodiments, for differentiation and without loss of generality, the network device is represented by a first device and the first type of terminal device (e.g., NR reccap UE) is represented by a second device.

S801 the first device determines a third frequency resource.

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

In one possible implementation, 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, a frequency resource (which may correspond to a third frequency resource) for transmitting the PUCCH and a frequency resource (which may correspond to a fourth frequency resource) for transmitting the PUSCH may be the same frequency resource. That is, if the frequency resource for transmitting the PUCCH is also included within the frequency resource for transmitting the PUSCH, the maximum frequency resource range for transmitting the PUCCH is the same as the frequency resource range for transmitting the PUSCH. For example, in the prior art, the terminal device performs data transmission with the network device through an active BWP at any time, the frequency resource range of the PUSCH transmission resource in the BWP may be a frequency resource range composed of the lowest-frequency RB to the highest-frequency RB included in the BWP, and the frequency resource range of the PUCCH transmission resource in the BWP may be configurable, but the configurable frequency resource range may also be a frequency resource range composed of the lowest-frequency RB to the highest-frequency RB included in the BWP. In addition, in general, in order to ensure the performance of PUCCH transmission, the terminal device may use a PUCCH frequency hopping transmission method in a slot, so that the PUCCH transmission obtains a frequency diversity gain, for example, the PUCCH may determine a specific frequency resource (represented by PRB) to be transmitted in the slot, where in one slot, the PRB index corresponding to the frequency resource of the first-hop PUCCH is PRB index

The index of a Physical Resource Block (PRB) corresponding to the frequency resource of the second-hop PUCCH is

Wherein C is related to the PUCCH resource index and the total number of initial cyclic indexes allocated for the PUCCH resources,

the PRB index configured for the terminal device for the network device for the PUCCH transmission corresponds to the PRB or RB,

the BWP frequency-domain resource size for including the PUCCH transmission may be alternatively understood as a BWP frequency resource range, where the BWP frequency resource range or frequency resource size may be represented by the number of PRBs or RBs included within the BWP. Based on the above formula, it can be understood that the maximum frequency resource range for transmitting PUCCH is the BWP frequency resource size or the BWP frequency resource range including the PUCCH transmission (e.g. when the BWP frequency resource size is smaller than the BWP frequency resource range)

And C ═ 0). Considering that the BWP may also include PUSCH transmissions, the network device may schedule the PUSCH frequency resources of the terminal device to be distributed throughout the BWP. For terminal devices with unlimited bandwidth, such as NR Legacy terminal devices (which may correspond to the second type terminal device in the embodiment of the present application), since the bandwidth may reach 100MHz, the maximum frequency resource range for PUCCH transmission and the maximum frequency resource range for PUSCH transmission may both be 100MHz, which may implement PUCCH frequency hopping gain and may ensure PUSCH transmission performance. However, for a terminal device (corresponding to the second device or the first type terminal device in the embodiment of the present application) with limited bandwidth or low capability, since the bandwidth capability of the terminal device is limited, for example, only 20MHz, in order to ensure the PUCCH frequency hopping transmission performance, the maximum third frequency resource range including PUCCH transmission can only be the channel bandwidth of the terminal device, for example, 20MHz, so that the maximum frequency resource range of PUSCH transmission can only be 20MHz by using the prior art, the frequency selective scheduling gain of PUSCH transmission is limited, and generally, the larger the maximum frequency resource range for transmitting PUSCH is, the greater the flexibility of scheduling PUSCH transmission is, and the more the frequency selective scheduling gain can be obtained. Based on this, in the embodiment of the present application, for the first type terminal device, the frequency resource range of the frequency resource used for transmitting the PUCCH of the type terminal device, that is, the third frequency resource, may be different from the frequency resource range of the frequency resource used for transmitting the PUSCH of the type terminal device, that is, the fourth frequency resource. For a first type of terminal equipment,through decoupling design of the third frequency resource and the fourth frequency resource, realization of PUCCH frequency hopping can be guaranteed, frequency-selective scheduling gain of PUSCH transmission can be guaranteed, PUCCH transmission and PUSCH transmission can be optimized respectively, and data transmission performance of the first type terminal equipment is improved.

In a possible implementation manner, the frequency resource range of the third frequency resource is smaller than that of the fourth frequency resource, which is helpful for improving the frequency selective 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 terminal device, for example, the bandwidth capability of the first type terminal device is 20MHz, and then the frequency resource range of the third frequency resource is 20 MHz. Therefore, the frequency hopping gain of the PUCCH can be ensured, and the influence on the number of symbols transmitted by the PUCCH can be avoided. Conversely, if the frequency resource range size of the third frequency resource is larger than the bandwidth capability of the first type terminal device, considering the PUCCH transmission, the first type terminal device needs to consider a Radio Frequency (RF) tuning time between the first-hop PUCCH and the second-hop PUCCH, where the RF tuning time generally corresponds to several Orthogonal Frequency Division Multiplexing (OFDM) symbols, that is, the first type terminal device cannot perform data transmission with the network device (corresponding to the first device in the embodiment of the present application) during the RF tuning time, which results in that the number of symbols used for PUCCH transmission in one slot is reduced, and the PUCCH transmission performance is affected.

Fig. 9 is a schematic diagram of frequency resource ranges suitable for the embodiment of the present application. As shown, the maximum frequency resource range for PUSCH transmission of the first type of terminal device is different from the maximum frequency resource range for PUCCH transmission, e.g., the maximum frequency resource range for PUSCH transmission may be greater than the maximum frequency resource range for PUCCH transmission. Wherein, within the maximum frequency resource range for the PUCCH transmission, other resources not allocated to the PUCCH transmission may be used for the PUSCH transmission. It should be noted that the maximum frequency resource range for PUSCH transmission means that PUSCH transmission resources scheduled by the network device to the first type of terminal device may be distributed on any one or more frequency domain resource units, e.g., RBs, included in this maximum frequency resource range. Furthermore, in fig. 9, the frequency resources used for PUCCH transmission within the maximum frequency resource range used for PUCCH transmission is only one exemplary implementation, and PUCCH transmission frequency resources between the first type terminal device and the network device may also be distributed on other frequency domain resource units, e.g., RBs, included in pairs in the maximum frequency resource range used for PUCCH transmission.

Fig. 10 is another schematic diagram of frequency resource ranges suitable for the embodiments of the present application. As shown in the figure, the maximum frequency resource for PUSCH transmission referred to herein may refer to a resource range between a minimum frequency location that can be occupied for PUSCH transmission and a maximum frequency location that can be occupied.

In the embodiment of the present application, the maximum frequency resource range for PUSCH transmission may overlap with the maximum frequency resource range for PUCCH transmission, or the maximum frequency resource range for PUSCH transmission may also include the maximum frequency range for PUCCH transmission, or there is no overlap between the maximum frequency resource range for PUSCH transmission and the maximum frequency resource range for PUCCH transmission, for example, distributed in Frequency Division Multiplexing (FDM).

For example, the frequency resource in the embodiment of the present application may correspond to a BWP, for example, the third frequency resource corresponds to a third BWP including PUCCH transmission, and the fourth frequency resource corresponds to a fourth BWP including PUSCH transmission. When the first type terminal equipment determines PUCCH transmission resources through the formula, the second hop PUCCH transmission resources correspond to

In (1)

Corresponding to the third BWP size (e.g., the third BWP size may be the number of frequency domain resource units included in the third BWP). First of allAnd when the type terminal equipment determines the PUSCH transmission resource, determining the position of the PUSCH transmission resource according to the fourth BWP. Further, if the first device enables PUSCH frequency hopping transmission of the first type terminal device, the first type terminal device determines a frequency resource corresponding to the PUSCH frequency hopping transmission according to the fourth BWP size (for example, the fourth BWP size may be the number of frequency domain resource units included in the fourth BWP).

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

In the embodiment of the present application, the maximum frequency resource range for transmitting the PUSCH does not mean that all frequency resources are used for transmitting the PUSCH within the frequency resources including the PUSCH transmission (for example, the fourth frequency resource), but means that, of all possible frequency resources used for the PUSCH transmission, the frequency resource range corresponding to the RB with the lowest frequency and the RB with the highest frequency corresponding to the PUSCH transmission is regarded as the maximum frequency resource range for transmitting the PUSCH within the frequency resources including the PUSCH transmission (for example, the third frequency resource). For example, in the fourth frequency resource range, at a certain time, the PUSCH transmission may include the RB with the lowest frequency included in the fourth frequency resource range, and at another time, the PUSCH transmission may include the RB with the highest frequency included in the fourth frequency resource range, that is, the PUSCH transmission may be flexibly distributed in the fourth frequency resource range including the PUSCH transmission, and the maximum frequency resource range for transmitting the PUSCH is the frequency resource range corresponding to the fourth frequency resource.

It should be noted that, in this embodiment of the application, the maximum frequency resource transmission range corresponding to the PUSCH (that is, the fourth frequency resource or the fourth frequency resource range) may be any one of a frequency range corresponding to a system uplink carrier notified by the first device, a frequency range corresponding to an uplink channel bandwidth configured for the second device by the first device, or a frequency range corresponding to an uplink initial BWP bandwidth configured for the second type terminal device by the first device, or it may also be understood that the fourth frequency resource may be any one of a system uplink carrier notified by the first device, an uplink channel corresponding to the second device (configured by SIB1 or RRC dedicated signaling), or an uplink initial BWP corresponding to the second type terminal device. The second type terminal device is a terminal device with different capability from the first type terminal device, for example, a terminal device with different bandwidth capability. Since the second device may determine to access with the first device, the uplink bandwidth information of the system carrier sent by the first device by means of the broadcast information may be received by the second device, and may also receive the uplink initial BWP bandwidth configured by the first device for the second type terminal device (for example, the uplink initial BWP corresponding to the second type terminal device is determined by receiving SIB 1).

It should be understood that, in some specific embodiments, when the first device may directly determine the frequency resource for transmitting the PUCCH, this step is an optional step, namely: the first device may directly determine the frequency resource for transmitting the PUCCH without determining the third frequency resource, and further determine a frequency resource range of the frequency resource for transmitting the PUCCH, where the frequency resource range of the frequency resource for transmitting the PUCCH is different from a frequency resource range of a fourth frequency resource, and the fourth frequency resource includes a frequency resource for transmitting a physical uplink shared channel PUSCH.

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

The first device sends indication information to the second device, wherein the indication information comprises second indication information and/or third indication information.

Illustratively, when the first device determines to transmit frequency resources of a PUCCH, the first device transmits the second indication information indicating the frequency resources of the PUCCH.

Illustratively, when the first device determines the third frequency resource, the first device transmits the second indication information indicating the third frequency resource, i.e., the frequency resource including the PUCCH transmission.

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

The first device transmits third indication information indicating the fourth frequency resource, i.e., 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 configuration information of the BWP. Optionally, the third indication information is used to indicate a 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, and the PUSCH transmission configuration information included in the fourth frequency resource.

It is understood that by indicating the third frequency resource and the fourth frequency resource respectively by the second indication information and the third indication information, decoupling configuration of the maximum frequency resource range including the PUCCH transmission and the maximum frequency resource range including the PUSCH transmission can be achieved, so that optimization design for PUCCH transmission and PUSCH transmission respectively can be achieved, for example, considering the influence of the bandwidth capability of the first type terminal device on PUCCH frequency hopping transmission, the maximum frequency resource range including PUCCH transmission is not greater than the bandwidth capability of the first type terminal device. On the other hand, the maximum frequency resource range which is different from the third frequency resource range and is used for PUSCH transmission is configured, so that the flexible scheduling of the PUSCH can be ensured, and as for the influence of the bandwidth capability of the first type of terminal equipment on the PUSCH transmission performance, only the PUSCH transmission resource scheduled each time is required to be ensured not to exceed the bandwidth capability of the first type of terminal equipment, but the frequency resource position of the scheduled PUSCH can be flexibly scheduled in a fourth frequency resource range different from the third frequency resource, so that the PUSCH frequency selection scheduling gain is ensured.

Considering that, in the unconnected state, the transmission of the PUCCH is mainly HARQ-ACK feedback for Message 4 or Message B, so that the maximum frequency resource range (i.e., the resource range of the third frequency resource or the third frequency resource) for PUCCH transmission may be transmitted through Message 4 or Message B in the random access procedure, specifically may be carried through a PDCCH that schedules Message 4 or Message B, or may be carried through a PDSCH that includes Message 4 or Message B.

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

In one possible implementation manner, the first device may indicate the third frequency resource to the second device by broadcasting an information notification. For a specific introduction of the broadcast information notification manner, reference may be made to the description in S602, and for brevity, details are not described here again.

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

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

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

It should be noted that, in this embodiment of the application, the first information and the second information may be carried in a system broadcast signaling, an RRC dedicated signaling, a physical layer control signaling, or a Media Access Control (MAC) signaling, and notification manners 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 may be understood as 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 range for PUSCH transmission may be implemented directly by scheduling PUSCH transmission without additional definition, that is, the maximum frequency resource range for PUSCH transmission may be implicitly determined by scheduling the location of PUSCH transmission. The benefit achieved in this way is that the transmission of the PUSCH can be achieved through data scheduling, even if the bandwidth capability of the second device is limited, as long as the scheduled PUSCH transmission bandwidth is guaranteed not to be greater than the bandwidth capability of the second device at each data scheduling, and frequency hopping of the PUSCH can also be achieved through scheduling. However, PUCCH transmission is different, because multi-user multiplexing is considered, PUCCH transmission is not as flexible and dynamic scheduling as PUSCH transmission, and a frequency resource range needs to be considered to support PUCCH transmission frequency hopping.

S803 the second device determines a third frequency resource.

Illustratively, the second device may directly determine the frequency resources used for transmitting the PUCCH. The frequency resource for transmitting the PUCCH is included in a third frequency resource, where a frequency resource range of the third frequency resource is different from a frequency resource range of a fourth frequency resource, and the fourth frequency resource includes a frequency resource for transmitting a physical uplink shared channel PUSCH. Optionally, the frequency resource range of the third frequency resource is smaller than the frequency resource range of the fourth frequency resource.

Illustratively, the second device may determine a 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 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, configure the third frequency resource through the second indication information, and the maximum frequency resource range for PUSCH transmission may be implemented directly 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 benefit achieved in this way is that the transmission of the PUSCH can be achieved through data scheduling, even if the bandwidth capability of the second device is limited, as long as the scheduled PUSCH transmission bandwidth is guaranteed not to be greater than the bandwidth capability of the second device at each data scheduling, and frequency hopping of the PUSCH can also be achieved through scheduling. However, PUCCH transmission is different because, considering multi-user multiplexing, PUCCH transmission is not as flexible and dynamic scheduling as PUSCH transmission, and a frequency resource range needs to be considered to support PUCCH transmission frequency hopping, based on which, the second device may determine a PUCCH transmission frequency resource range according to a maximum frequency range of PUCCH transmission configured by the first device, and determine a frequency resource range corresponding to the fourth frequency resource according to an association relationship between a scheduled PUSCH transmission resource and the maximum frequency resource range for PUSCH transmission, so that data transmission performance of the second device can be ensured, and overhead indicated by the maximum frequency resource range for data transmission does not increase too much.

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

In one possible implementation, the maximum frequency resource range (i.e., the third frequency resource) 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 greater than the third frequency resource or greater 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 different from the maximum frequency resource range used for PUSCH transmission (i.e., the frequency resource range corresponding to the fourth frequency resource) and the maximum frequency resource range used for PUCCH transmission (i.e., the frequency resource range corresponding to the third frequency resource). At present, in the NR system, the transmission bandwidth corresponding to each random access preamble resource sequence does not exceed 20MHz, that is, the second device can directly utilize the existing random access preamble resource to implement initial access, although all frequency resource of frequency division multiplexing RACH occasion (FDMed RACH occasion, FDMed RO) is considered, and the frequency resource range thereof exceeds the transmission bandwidth of the second device, for each random access preamble resource transmission, the transmission bandwidth thereof is within the bandwidth capability range of the second device, and in addition, for PUSCH transmission, transmission within a larger frequency resource range can be implemented in a scheduling manner as described above, only it is required to ensure that the transmission bandwidth of PUSCH does not exceed the bandwidth capability of the second device each time, but for PUCCH, the defined frequency resource range needs to be considered, and therefore, the configuration of the maximum frequency resource range corresponding to each channel can be considered independently, the data transmission performance of each channel is guaranteed.

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

In a possible implementation manner, in this embodiment of the 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 is to be understood that, in this case, the fourth indication information is the third indication information, or the third indication information and the fourth indication information are different information, but indicate the same range.

In the 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, different channel adaptation channel characteristics can be respectively designed and optimized, so as to meet the transmission requirements of the first type terminal device, in particular, each channel of the first type terminal device with low bandwidth capability.

Fig. 11 is another schematic diagram of frequency resource ranges suitable for the embodiments 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 for random access preamble resource transmission, the maximum frequency resource range for PUCCH transmission, and the maximum frequency resource range for PUSCH transmission may have different sizes 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 within the third frequency resource.

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

Illustratively, the second device transmits the PUCCH in a third frequency resource after determining the frequency resource for transmission of the PUCCH. Correspondingly, the first device receives the PUCCH from the second device within the third frequency resource.

In this embodiment of the application, a maximum frequency resource range corresponding to the second device sending the random access preamble resource may be different from both a maximum frequency resource range used for PUSCH transmission and a 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 may have different corresponding sizes, and in one possible implementation, 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 may further configure a maximum frequency resource range of PUCCH transmission and a maximum frequency resource range of PUSCH transmission corresponding to the second type terminal device. For example, in the random access process, the first device may configure a maximum frequency resource range of PUCCH transmission and a maximum frequency resource range of PUSCH transmission corresponding to the uplink initial BWP corresponding to the second type terminal device, 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 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 for transmitting the PUCCH corresponding to the terminal device of the second type (also the maximum frequency resource for transmitting the PUSCH corresponding to the terminal device of the second type) may be used as the fourth frequency resource in the embodiment of the present application, that is, the maximum frequency resource for transmitting the PUSCH corresponding to the terminal device of the first type. Optionally, the configuration information used by the first device to configure the maximum frequency resource range of the PUCCH transmission and the maximum frequency resource range of the PUSCH transmission corresponding to the second type terminal device may be different from the second indication information, the third indication information, and the fourth indication information in the above description.

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

In this embodiment, the frequency resources for transmitting the PUCCH, including M frequency resources, in the N second frequency resources may be enabled by a network device (as an implementation manner of the first device in this embodiment). For example, when the network device does not enable the characteristic, 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 is equal to N.

In the embodiment of the present application, the frequency resource range of the third frequency resource different from the frequency resource range of the fourth frequency resource may be enabled by a network device (as an implementation manner of the first device in the embodiment of the present application). The frequency resource range of the third frequency resource is equal to the frequency resource range of the fourth frequency resource, for example, when the network device does not enable the feature. It should be noted that, in the embodiment of the present application, the first frequency resource, the second frequency resource, the third frequency resource, and the fourth frequency resource may be used to transmit uplink data of the first type terminal device in an RRC idle state, and may also be used to transmit uplink data of the first type terminal device in an RRC connected state or an inactive state.
