Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a resource information indication method and device. Background Art

[0002] To access the 5th generation mobile networks (5G) new radio (NR) network, the terminal device needs to go through the process of cell search, system information acquisition, and random access to better receive the communication services of the 5G NR network. Only after the terminal device obtains the system information of the cell can it learn how the cell is configured, so as to better access the cell and receive communication services in the cell.

[0003] System information includes a master information block (MIB) and multiple system information blocks (SIBs). When a terminal device attempts to access a network device, it will receive MIB or SIB information. Since the network device will limit the number of terminal devices that can access the cell and send a prohibited cell access message, the terminal device will not access the cell when it receives the prohibited cell access message. In actual applications, this access method cannot flexibly indicate that one or more types of terminal devices can access the cell, and another type or types of terminal devices can be prohibited from accessing the cell. Summary of the invention

[0004] The present application provides a resource information indication method and apparatus to indicate whether a first terminal device is supported to access a network device, and to indicate the resources used by the first terminal device to access the network device.

[0005] In a first aspect, the present application provides a resource information indication method, comprising:

[0006] The network device determines first indication information, wherein the bit state of the first indication information is a bit state in a first state set, and the network device supports the first terminal device to access the network device, and / or the bit state of the first indication information is a bit state in a second state set, and the network device does not support the first terminal device to access the network device; the network device sends first information, and the first information includes first indication information.

[0007] The network device indicates whether it supports the first terminal device to access the network device through different bit states. The network device mentioned in this application supports the first terminal device to access the network device, which means that the network device has the ability to support the terminal device to access the network device, or the network device allows the terminal device to access the network device. The first indication information can be 1 bit or multiple bits. The bit state in the first state set can be 1 bit state or multiple bit states, and the bit state in the second state set can be 1 bit state or multiple bit states. Among them, the number of bits in the first state set is the same as the number of bits in the second state set, such as: if the bit state of the first state set is 1 bit, then the bit state of the second state set is also 1 bit. The prior art does not provide indication information for indicating the first terminal device to access the network device. The solution provided in this application is more suitable for the load balancing requirements when the first terminal device accesses the network device.

[0008] In a possible implementation manner, the first information includes: a main information block sent by the network device.

[0009] In the present application, the first information includes a main information block, so that the network device can send the first indication information through the main information block.

[0010] In a possible implementation manner, the master information block further includes second indication information, wherein the second indication information is cellBarred information, and the cellBarred information is not applied to the first terminal device.

[0011] On the premise that the first information includes a main information block sent by the network device, the main information block also includes second indication information. The second indication information may be cellBarred information. The cellBarred information is usually not used to determine whether the network device supports access to the first terminal device.

[0012] The second indication information in the present application is not applied to the first terminal device. It can be understood that when the state of the second indication information is that the access network device is not supported, the state is invalid for the first terminal device, and independent control of whether the network device supports the first terminal device to access the network device can be achieved.

[0013] In a possible implementation manner, the first information includes: downlink control information or system information block sent by the network device.

[0014] In the present application, the first information includes downlink control information or a system information block. The system information block is carried in a downlink shared channel scheduled by the downlink control information. The network device can send the first indication information through the downlink control information or the system information block. The reserved bits in the downlink control information or the system information block, that is, the available bits are more, which is more conducive to the sending of the first indication information.

[0015] In a possible implementation, before the network device sends the first information, it also includes: the network device sends a main information block to the first terminal device; the main information block includes cellBarred information; and the cellBarred information is not applied to the first terminal device.

[0016] In the present application, the network device sends a main information block before sending the first information, and the first information is downlink control information or a system information block. Before sending the first information, the main information block has been sent, and the main information block includes cellBarred information, and the cellBarred information is not applied to the first terminal device, that is, the content indicated by the cellBarred information is invalid for the first terminal device, and independent control of whether the network device supports the first terminal device to access the network device can be achieved.

[0017] In a possible implementation manner, the network device sends third indication information for indicating a broadcast channel type;

[0018] The state of the third indication information is 0, and the first information is a main information block included in the broadcast channel; or

[0019] The state of the third indication information is 1, and the first information includes an extended information block included in the broadcast channel;

[0020] The extended information block does not include cellBarred information, and / or the extended information block includes fourth indication information.

[0021] In the present application, the extended information block may be an information block dedicated to the first terminal device, which includes one or more bits, or one or more information, for example, the extended information block does not include cellBarred information, and the extended information block includes fourth indication information; or, the extended information block does not include cellBarred information; or, the extended information block includes fourth indication information. The fourth indication information may be 1 bit or multiple bits, for example, the fourth indication information may be 1 bit, and the 1 bit is used as a reserved bit; or the fourth indication information may be 1 bit, and one of the states of the 1 bit is used to indicate extended information, messageClassExtension; or the fourth indication information may be multiple bits, used to indicate a synchronization resource or a control resource set. The state of 0 and the state of 1 may also be used to distinguish between the two states, and this is not limited. It should be noted that the third indication information is carried and sent via a broadcast channel. In this case, the first information is a broadcast channel, and the third indication information may be 1 bit of choice information.

[0022] In a possible implementation, the first indication information is indicated by 1 bit, the bit state of the first indication information is a bit state in a first state set, the bit state of the second indication information is a third state, and the network device supports the first terminal device to access the network device; or, the bit state of the first indication information is a bit state in a first state set, the bit state of the second indication information is a fourth state, and the network device supports the first terminal device to access the network device; or, the bit state of the first indication information is a bit state in a second state set, the bit state of the second indication information is the third state, and the network device does not support the first terminal device to access the network device; or, the bit state of the first indication information is a bit state in a second state set, the bit state of the second indication information is the fourth state, and the network device does not support the first terminal device to access the network device; wherein, the third state and the fourth state include 0 and 1; the third state is different from the fourth state.

[0023] The second indication information is the third state or the fourth state, the third state includes 0 or 1, the fourth state includes 1 or 0, when the third state is 1, the fourth state is 0; when the third state is 0, the fourth state is 1. The bit state of the first state set and the second indication information can jointly indicate whether the network device supports access to the network device.

[0024] This method can more flexibly indicate the access status of the first terminal device. Compared with the prior art which does not provide indication information for indicating the first terminal device to access the network device, the solution provided by the present application is more suitable for the load balancing requirement when the first terminal device accesses the network device.

[0025] In one possible implementation, the first indication information is indicated by 2 bits, the network device supports the first terminal device to access the network device, and the bit state of the first indication information includes a first state set; the first state set includes: {10, 11} or {01, 11}; the network device does not support the first terminal device to access the network device, and the bit state of the first indication information includes: a first state set; the first state set includes: {00, 01} or {00, 10}; wherein, the first state set indicates that the network device supports the first terminal device to access the network device; the second state set indicates that the network device does not support the first terminal device to access the network device; the first state set is different from the second state set.

[0026] The first indication information is indicated by 2 bits. When the first state set is {10, 11}, the second state set is {00, 01}; when the first state set is {01, 11}, the second state set is {00, 10}. The first state set indicates that the network device supports the first terminal device to access the network device; the second state set indicates that the network device does not support the first terminal device to access the network device.

[0027] This method can more flexibly indicate the access status of the first terminal device. Compared with the prior art which does not provide indication information for indicating the first terminal device to access the network device, the solution provided by the present application is more suitable for the load balancing requirement when the first terminal device accesses the network device.

[0028] In one possible implementation, the bit state of the first indication information and / or the bit state of the second indication information are used to indicate the access method of the first terminal device to access the network device; for the same associated information, different access method associated information formats are different; the associated information of the access method includes one or more of the following: synchronization resource information, control resource set information, access resource information, system information block information, data channel resource information, aggregation level information supported by the control resource set, control channel resource information, control channel symbol number information, search space configuration information, first channel repetition number information, uplink bandwidth part information, downlink bandwidth part information.

[0029] It should be noted that the bit state of the first indication information, and / or the bit state of the second indication information can indicate the access method of the first terminal device to the network device, and different access methods correspond to different associated information formats. Different access methods correspond to different associated information formats, which can be understood as different content of the same associated information. For example, the associated information is the information of the control resource set. The control resource set for accessing the network device using the first access method is a configured time-frequency resource CORESET#0, and the control resource set for accessing the network device using the second access method is a resource set with a time domain offset relative to CORESET#0. The access method can be a shared access method, or an independent access method, or the access method corresponds to the associated information.

[0030] In addition, according to the above, the second indication information is not applied to the first terminal device, but can be applied to the second terminal device. The first characteristics of the first terminal device and the second terminal device are different, wherein the parameters of the first characteristic include at least one of the following: bandwidth (channel bandwidth), number of supported or configured resource units (resource units can be RBs, REs, subcarriers, RB groups, resource element groups (resource element group, REG) bundles, control channel elements, subframes, radio frames, time slots, mini-time slots, symbols), number of transmitting antenna ports and / or number of receiving antenna ports, number of RF channels, number of hybrid automatic repeat request (hybrid automatic repeat request, HARQ) processes, supported peak rates, application scenarios, latency requirements, processing capabilities, protocol versions, duplex modes (half-duplex, full-duplex), services (IoT applications such as video surveillance, mobile broadband (MBB), etc.). The resource units appearing in this application are all the contents contained in the above-mentioned resource units.

[0031] In addition, the synchronization resource information includes one or more of the time domain resource position, frequency domain resource position, resource index, number of resource units, bandwidth, and transmission period of SSB. When the first terminal device accesses the network device, it uses a different synchronization information block (SS / PBCH block, SSB) from the second terminal device to access, which is beneficial to load balancing. Alternatively, when the first feature of the first terminal device is different from the first feature of the second terminal device, for example, when the channel bandwidth supported by the first terminal device is smaller than that of the second terminal device, the first terminal device cannot use the same SSB as the second terminal device to access the network device, and a dedicated SSB is required.

[0032] The information of the control resource set includes the time domain resource position, frequency domain resource position, resource index, number of resource units, bandwidth or more of the control resource set (CORESET), such as the number of resource units of CORESET#0. In CORESET#0, the UE performs blind detection on the physical downlink control channel (PDCCH), which is used to schedule the physical downlink shared channel (PDSCH) carrying SIB1.

[0033] The information on access resources includes one or more of the time domain resource position, frequency domain resource position, resource index, number of resource units, bandwidth, sequence transmission period, and mapping relationship with SSB of random access resources, or one or more of the time domain resource position, frequency domain resource position, resource index, number of resource units, and bandwidth of initial access resources.

[0034] The information of the system information block includes whether the system information block is shared.

[0035] The information of the data channel resources includes one or more of the time domain resource position, the frequency domain resource position, the resource index, the number of resource units, the bandwidth, and whether they are shared. For example, the data channel is a data channel carrying SIB1.

[0036] Information on the aggregation level supported by the control resource set: specifically, the control channel element (CCE) aggregation level supported by the control resource set. Supporting a larger aggregation level can improve the reception performance of the control channel. The first terminal device and the second terminal device can be configured with different maximum aggregation levels supported by the control resource set.

[0037] Information on control channel resources: associated with the channel bandwidth and / or subcarrier space (SCS) supported by the first terminal device, and based on the channel bandwidth, a larger number of resource units is selected as much as possible. The number of resource units of the control channel of the first terminal device is greater than the number of resource units of the control channel of the second terminal device.

[0038] Information on the number of symbols of the control channel: The number of symbols of the control channel is associated with the control resource and the supported aggregation level. An increase in the number of symbols of the control channel is conducive to an increase in the aggregation level. The number of control channel symbols of the first terminal device is greater than that of the second terminal device.

[0039] Information about search space configuration: The search space configuration of the control channel of the first terminal device may be different from the search space configuration of the second terminal device. For example, the detection period of the search space is different, the number of search spaces in each time unit, and the time position of monitoring the downlink control channel in each time unit.

[0040] Information about the number of repetitions of the first channel: The number of repetitions of the first channel sent or received by the first terminal device can be explicitly or implicitly configured. Multiple repetitions of the first channel can improve the performance of the first channel and facilitate decoding.

[0041] The information of the uplink bandwidth part (BWP) includes the time domain resource position, frequency domain resource position, resource index, number of resource units, and one or more bandwidths of the initial uplink BWP, or the time domain resource position, frequency domain resource position, resource index, number of resource units, and one or more bandwidths of the uplink activated BWP.

[0042] The information of the downlink BWP includes the time domain resource position, frequency domain resource position, resource index, number of resource units, bandwidth or more of the initial uplink BWP, or the time domain resource position, frequency domain resource position, resource index, number of resource units, bandwidth or more of the downlink activated BWP.

[0043] In this way, while indicating whether the first terminal device is supported to access the network device, the associated information can be indicated, so that the resources used by the first terminal device to access the network device can be flexibly indicated.

[0044] In a possible implementation, the main information block or the downlink control information or the system information block also includes a first parameter, which includes one or more of the following parameters: information on synchronization resources of the first terminal device, information on the aggregation level supported by the control resource set, information on the number of symbols of the control channel, information on the resource unit of the control channel, information on the search space configuration, and information on the number of repetitions of the first channel.

[0045] In the present application, the first parameter can be a bit in the first information, or can be an independent field in the first new message. The information indicated in the first parameter is information dedicated to the first terminal device, which is beneficial to the performance improvement of the first terminal device. For example, a lower channel code rate can be achieved, and the decoding performance of the first terminal device for the downlink control channel can be improved, interference can be reduced, the signal-to-noise ratio of the control channel can be improved, and the coverage of the downlink control channel can be improved.

[0046] In a possible implementation, the aggregation level supported by the control resource set is greater than or equal to a first threshold; wherein the first threshold includes 8*n, and n is a positive integer greater than or equal to 1.

[0047] In the present application, increasing the aggregation level supported by the control resource set in this way is beneficial to the performance improvement of the first terminal device. For example, a lower channel code rate can be achieved, the decoding performance of the first terminal device for the downlink control channel can be improved, interference can be reduced, and the signal-to-noise ratio of the control channel can be improved.

[0048] In a possible implementation manner, the number of symbols in the symbol number information of the control channel is greater than or equal to a second threshold, where the second threshold includes 3 or 4.

[0049] In the present application, increasing the aggregation level supported by the control resource set in this way is beneficial to the performance improvement of the first terminal device. For example, a lower channel code rate can be achieved, the decoding performance of the first terminal device for the downlink control channel can be improved, interference can be reduced, and the signal-to-noise ratio of the control channel can be improved.

[0050] In a possible implementation, the number of repetitions of the first channel is associated with at least one of information on an aggregation level supported by a control resource set, information on a resource unit of a control channel, the number of symbols of the control channel, and information on a search space configuration.

[0051] In the present application, the first parameter can be a bit in the first information, or can be an independent field in the first new message. The information indicated in the first parameter is information dedicated to the first terminal device, which is beneficial to the performance improvement of the first terminal device. For example, a lower channel code rate can be achieved, and the decoding performance of the first terminal device for the downlink control channel can be improved, interference can be reduced, the signal-to-noise ratio of the control channel can be improved, and the coverage of the downlink control channel can be improved.

[0052] In a second aspect, the present application provides a resource information indication method, including: a first terminal device obtains first information, the first information includes first indication information; the first terminal device demodulates the first information to obtain the first indication information; the bit state of the first indication information is a bit state in a first state set, and the network device supports the first terminal device to access the network device, and / or the bit state of the first indication information is a bit state in a second state set, and the network device does not support the first terminal device to access the network device.

Among them, the number of bits in the first state set is the same as the number of bits in the second state set, such as: if the bit state of the first state set is 1 bit, then the bit state of the second state set is also 1 bit. The prior art does not provide indication information for indicating the first terminal device to access the network device.

[0099] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. The specific operation method in the method embodiment can also be applied to the device embodiment or the system embodiment. In the description of the present application, unless otherwise specified, the meaning of "multiple" is two or more.

[0100] In order to better illustrate the solution of the present application, the terms used in the present application are explained below:

[0101] Network equipment: a node in a radio access network (RAN), which can also be called a base station or a RAN node (or equipment). At present, some examples of access network equipment are: transmission reception point (TRP), evolved node B (eNB), radio network controller (RNC), node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wifi) access point (AP), or network equipment in a 5G communication system, or network equipment in a possible future communication system, or satellite. The network device may also be other devices with network device functions, for example, the network device may also be a device that functions as a network device in device-to-device (D2D) or machine-to-machine (M2M) communications, such as a vehicle networking device. The network device may also be a network device in a possible future communication system.

[0102] Terminal equipment: It can also be called user equipment (UE), mobile station (MS), mobile terminal (MT), etc. It is a device that provides voice or data connectivity to users, and can also be an IoT device. For example, terminal equipment includes handheld devices with wireless connection functions, vehicle-mounted devices, etc. At present, the terminal device can be: a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device (such as a smart watch, a smart bracelet, a pedometer, etc.), a vehicle-mounted device (such as a car, a bicycle, an electric car, an airplane, a ship, a train, a high-speed train, etc.), a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a smart home device (such as a refrigerator, a television, an air conditioner, an electric meter, etc.), an intelligent robot, a workshop device, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, or a wireless terminal in a smart home, a flying device (such as an intelligent robot, a hot air balloon, a drone, an airplane), etc. System information (SI) includes: MIB and multiple SIBs. To access the NR network, the UE needs to go through cell search, obtain system information, and random access. The main purpose of cell search is to obtain downlink synchronization, cell PCI, and new system information of the cell. During the cell search process, it is necessary to search SSB. The content contained in SSB is the primary synchronization signal (PSS), secondary synchronization signal (SSS), demodulation reference signal (DMRS), and PBCH. Through SSB, the UE can obtain downlink synchronization, cell PCI, and SI of the cell. The UE needs to obtain the SI of the cell to know how the cell is configured so that it can access the cell and work correctly in the cell. SI is cell-level information and is effective for all UEs accessing the cell.

[0103] It should be noted that the parameters that can be used to characterize the first feature of the terminal device in this application include one or more of the following:

[0104] Bandwidth (channel bandwidth), that is, the bandwidth supported or configured by the terminal device. In this application, the bandwidth of the first terminal device and the second terminal device may be different, such as: the bandwidth of the first terminal device is 20M, and the bandwidth of the second terminal device is 100M;

[0105] The number of resource units supported or configured, such as: the number of resources supported by the first terminal device is 48 RB, and the number of resources supported by the second terminal device is 96 RB;

[0106] The number of transmitting antenna ports and / or the number of receiving antenna ports, that is, the number of transmitting antenna ports and / or the number of receiving antenna ports of the first terminal device is different from that of the second terminal device, such as: the number of transmitting antenna ports of the first terminal device is 1, and the number of receiving antenna ports is 2, and the number of transmitting antenna ports of the second terminal device is 2, and the number of receiving antenna ports is 4;

[0107] The number of radio frequency channels, that is, the number of radio frequency channels of the first terminal device is different from that of the second terminal device, such as: the number of radio frequency channels of the first terminal device is 1, and the number of radio frequency channels of the second terminal device is 2;

[0108] The number of HARQ processes, that is, the number of HARQ processes supported by the first terminal device is different from that of the second terminal device, such as: the number of HARQ processes of the first terminal device is 8, and the number of HARQ processes of the second terminal device is 16;

[0109] The supported peak rate, that is, the maximum peak rates of the first terminal device and the second terminal device are different, such as: the maximum peak rate supported by the first terminal device is 100Mbps, and the peak rate supported by the second terminal device is 200Mbps;

[0110] Application scenarios, that is, the first terminal device and the second terminal device serve different application scenarios, such as: the first terminal device is used for industrial wireless sensing, video surveillance, wearable devices, etc., and the second terminal device is used for mobile communications, video surfing, etc.;

[0111] Delay requirement, that is, the first terminal device and the second terminal device have different requirements for transmission delay, such as: the delay requirement of the first terminal device is 500 milliseconds, and the delay requirement of the second terminal device is 100 milliseconds;

[0112] Processing capabilities, and different processing timing and processing speed of channels or data between the first terminal device and the second terminal device under different SCS conditions, such as: the first terminal device does not support complex operations (complex operations include artificial intelligence (AI) and virtual reality (VR) rendering), while the second terminal device supports complex operations; such as: the processing capability of the first terminal device is lower than that of the second terminal device;

[0113] Protocol version, that is, the first terminal device and the second terminal device belong to terminal devices of different protocol versions, such as: the protocol version supported by the first terminal device is Release 17, and the protocol version supported by the second terminal device is Release 15;

[0114] Duplex mode (half-duplex, full-duplex), such as: the first terminal device works in half-duplex mode, and the second terminal device works in full-duplex mode;

[0115] Services (IoT applications such as video surveillance, MBB, etc.), for example: the service supported by the first terminal device is video surveillance, and the service supported by the second terminal device is MBB.

[0116] In addition, for the same first feature parameter, different terminal devices have different first feature parameter values, and the performance of the first terminal device represented by the parameter value of the first feature is worse than that of the second terminal device. For example, the first terminal device supports a peak rate of 100Mbps, while the second terminal device supports a peak rate of 200Mbps. It can be seen that the performance of the first terminal device is worse than that of the second terminal device. In the present application, the first terminal device may be a REDCAPUE, and the second terminal device may be a legacy UE; or the first terminal device may be a terminal device whose parameter value of the first feature is worse than that of the second terminal device. No specific limitation is made here. Any terminal device whose parameter value of the first feature of the first terminal device is less than that of the first feature of the second terminal device meets the requirements of the first terminal device mentioned in the present application.

[0117] In related technologies, MIB is carried on the physical channel PBCH for transmission. Legacy UE can obtain the structure of MIB by decoding SSB, as follows:

[0118]

[0119] The structure of the above MIB shows the systemFrameNumber field, subCarrierSpacingCommon field, ssb-SubcarrierOffset field, dmrs-TypeA-Position field, pdcch-ConfigSIB1 field, cellBarred field, intraFreqReselection field, and spare field included in the MIB; wherein the systemFrameNumber field is used to indicate the system frame number, and SIZE (6) represents a bit string of 6 bits; the subCarrierSpacingCommon field is used to indicate SCS, scs15or6 0 means SCS is 15KHz or 30KHz, scs30or120 means SCS is 30KHz or 120KHz; the ssb-SubcarrierOffset field is used to indicate the frequency domain offset of the SSB relative to the reference point, and INTEGER (0..15) represents 16 optional values; the dmrs-TypeA-Position field is used to indicate the position of the downlink and uplink DMRS, and pos2 and pos3 represent the enumeration of the position; the pdcch-ConfigSIB1 field is used to indicate the information of the control resource set and the search space. PDCCH-ConfigSIB1 represents the control resource set (CORESET#0) with an index of 0 and the search space (search The configuration information of CORESET#0, SS#0) is as follows: for the frequency domain range 1 / 2, or different SCSs, CORESET#0 and SS#0 have 16 configurations, and the information of CORESET#0 and SS#0 is determined by indicating one configuration; the cellBarred field is used to indicate whether the network device allows legacy UE to access the network device, barred means not allowed, and notBarred means allowed; the intraFreqReselection field is used to indicate whether legacy UE can access the cell of the frequency point, allowed means allowing legacy UE to access the cell of the frequency point, and notAllowed means not allowing legacy UE to access the cell of the frequency point; the spare field is used to indicate that the field is a reserved field, and SIZE(1) indicates that the spare field is 1 bit. If the cellbarred field indicates barred, and the intraFreqReselection field indicates notAllowed, legacy UE is not allowed to access the entire frequency point.

[0120] In addition, it should be noted that SIB is carried in PDSCH for transmission, and PDSCH is scheduled by PDCCH. PDCCH includes one or more CCEs, which can be measured by aggregation level, that is, the number of consecutive CCEs occupied by PDCCH determines the size of the aggregation level. In related technologies, CCE aggregation level can usually be 1, 2, 4, 8, or 16.

[0121] CORESET represents a set of time-frequency resources used to carry PDCCH. A CORESET is composed of RB, time domain duration symbols. One UE can be configured with multiple CORESETs.

[0122] It should be noted that the pdcch-ConfigSIB1 field in the MIB indicates an element in the predefined resource set CORESET table. The information of CORESET#0 can be obtained through the CORESET table. The network device will send PDCCH in a candidate resource of CORESET, and the legacy UE will detect all candidate resources according to certain rules through blind detection (rules include detecting the type of aggregation level, different aggregation levels have different numbers of candidate resources, and detecting downlink control information with different scrambling methods) until the PDCCH is successfully decoded. In addition, CORESET#0 only supports aggregation levels 4, 8, and 16. For CORESET#0, the aggregation level is determined by (number of RBs in CORESET*number of symbols in CORESET) / 6.

[0123] Although the network access status of legacy UE can be indicated by information in MIB or SIB in the prior art, no solution for REDCAP UE to access network equipment is provided, so REDCAP UE cannot access network equipment and receive communication services through existing technical solutions. In addition, when there are too many terminals accessing the network equipment at the same time, the network equipment needs to control the access of REDCAP UE or legacy UE more flexibly.

[0124] In order to enable REDCAP UE to access network equipment and receive communication services, and for network equipment to more flexibly control access of REDCAP UE or legacy UE, the present application provides a resource information indication method so that REDCAP UE can access network equipment and receive communication services. Figure 1A system schematic diagram is provided for application of a resource information indication method provided in an embodiment of the present application, the system comprising: a network device, a first terminal device and a second terminal device, wherein the first terminal device may be a REDCAP UE and the second terminal device may be a legacy UE. Figure 1 Only one first terminal device and one second terminal device are illustrated, but the number of first terminal devices and second terminal devices is not limited in actual application. In this application, the network device can send MIB or SIB to the first terminal device and / or the second terminal device respectively to indicate whether the first terminal device and / or the second terminal device are supported to access the network device.

[0125] It should be noted that the network device mentioned in this application supports the first terminal device to access the network device, which means that the network device is capable of supporting the terminal device to access the network device, or the network device allows the terminal device to access the network device. The network device is capable of supporting the terminal device to access the network device because some network devices support terminal devices with specific first characteristics, but do not support terminal devices with other first characteristic parameters; the network device allows the terminal device to access the network device because the network device's load balancing is taken into account. If there are many terminal devices connected to the network device at the same time, the network device will not allow some terminal devices to access.

[0126] In order to enable the first terminal device to access the network device and receive communication services, the network device indicates whether the first terminal device is supported to access the network device, as well as resource usage information, through available bits in MIB or PBCH. It should be noted that the number of bits in MIB is 64, of which 1 bit can be used to indicate whether the first terminal device is supported to access the network device. It should be noted that when the number of SSBs in a half frame of the PBCH wireless frame is less than 64, that is, when Lmax<64, only 1 of the 3 highest bits of PBCH is used, and any one of the other 2 bits can be used to indicate whether the first terminal device is supported to access the network device.

[0127] See also Figure 2 A schematic diagram of a resource information indication method provided in an embodiment of the present application is specifically performed as follows:

[0128] Step 201, the network device determines first indication information, the bit state of the first indication information is a bit state in a first state set, and the network device supports the first terminal device to access the network device, and / or the bit state of the first indication information is a bit state in a second state set, and the network device does not support the first terminal device to access the network device.

[0129] Step 202: The network device sends first information, where the first information includes first indication information.

[0130] Step 203: The first terminal device obtains the first information, and demodulates the first information to obtain the first indication information.

[0131] Exemplarily, the first information can be carried by physical layer signaling or high-layer signaling or a broadcast channel. The physical layer signaling can be downlink control information, and the high-layer signaling can be radio resource control (RRC), medium access control control element (MACCE) signaling, which is not specifically limited here. In the present application, the first information may include a master information block MIB, a system information block SIB1, a downlink control channel (because SIB1 is carried in PDSCH for transmission, and PDSCH is scheduled by PDCCH), and a broadcast channel (which can be a logical channel or a physical channel).

[0132] Exemplarily, if the first information is MIB, the MIB contains first indication information, and the MIB may also contain second indication information. The second indication information may be a cellBarred field, and the cellBarred field is not applied to the first terminal device, or the field is invalid for the first terminal device.

[0133] In this application, when the first information is MIB, the cellBarred field is not applied to the first terminal device. The network device uses a dedicated field to indicate whether the first terminal device is supported to access the network, which is conducive to the indication of the dedicated network of the first terminal device. For example, in the industrial wireless sensors (IWS) in the factory scene, the location and number of terminal devices are relatively stable, and the use of a dedicated network can better guarantee the communication of the terminal devices. The dedicated field indicates whether the first terminal device is supported to access the network and is also conducive to the load balancing of the network device. It can control that only the first terminal device is allowed to access the network device in some scenarios, or only the second terminal device or other terminal devices are allowed to access the network device in some scenarios.

[0134] Exemplarily, the first information is SIB1 or PDCCH. Before sending the first information, the network device sends MIB, and the MIB includes a cellBarred field, which is not applied to the first terminal device, or the field is invalid for the first terminal device.

[0135] Exemplarily, when the first information is a broadcast channel, the network device may send third indication information for indicating the type of the broadcast channel, wherein the third indication information is 1-bit broadcast channel type indication information, for example, the third indication information may be 1-bit selection information (choice), the state selected by the third indication information is 0, and the first information is the MIB included in the broadcast channel; the state selected by the third indication information is 1, and the first information is an extended information block, and the extended information block may be an information block other than the MIB in the broadcast channel. The extended information block does not include the second indication information of whether the second terminal device is supported to access the network device, such as not including the cellBarred field, and / or the extended information block includes the fourth indication information of the broadcast channel, and the fourth indication information indicates other extended information blocks, and other extended information blocks can be used for indications compatible with subsequent versions of terminal devices.

[0136] In the present application, the extended information block may be an information block dedicated to the first terminal device, which includes one or more bits, or one or more information, for example, the extended information block does not include cellBarred information, and the extended information block includes fourth indication information; or, the extended information block does not include cellBarred information; or, the extended information block includes fourth indication information. The fourth indication information may be 1 bit or multiple bits, for example, the fourth indication information may be 1 bit, and the 1 bit is used as a reserved bit; or the fourth indication information may be 1 bit, and one of the states of the 1 bit is used to indicate extended information, messageClassExtension; or the fourth indication information may be multiple bits, used to indicate a synchronization resource or a control resource set. The state of 0 and the state of 1 may also be used to distinguish between the two states, and this is not limited. It should be noted that the third indication information is carried and sent via a broadcast channel. In this case, the first information is a broadcast channel, and the third indication information may be 1 bit of choice information. The structure of MIB has been described above and will not be repeated here. The structure of the extended information block can be that the extended information block does not include cellBarred information, and the extended information block includes the fourth indication information; or, the extended information block does not include cellBarred information; or, the extended information block includes the fourth indication information; the structure of the extended information block can also include the following information: synchronization information of one or more first terminal devices, information of control resource sets, SCS information, reference channel information, indication of system frame number information, and the first parameter. Other fields are not limited. The extended information block may also include the first parameter, and the method is the same as the method described in this application. The fields in the extended information block are shown in Table 1 below. Table 1 is only an exemplary description and is not specifically limited. Among them, the first field of the extended information block may indicate the fourth indication information; the second field may indicate the information of the synchronization resource; the third field may indicate the information of the control resource set; the fourth field may indicate the information of the SCS; the fifth field may indicate the information of the reference channel; the sixth field may indicate the system frame number information; and the seventh field may indicate the first parameter. The extended information block also includes other fields that are not illustrated one by one here.

[0139] In the present application, the extended information block may be an information block dedicated to the first terminal device, which includes one or more bits, or one or more information, for example, the extended information block does not include cellBarred information, and the extended information block includes fourth indication information; or, the extended information block does not include cellBarred information; or, the extended information block includes fourth indication information. The fourth indication information may be 1 bit or multiple bits, for example, the fourth indication information may be 1 bit, and the 1 bit is used as a reserved bit; or the fourth indication information may be 1 bit, and one of the states of the 1 bit is used to indicate extended information, messageClassExtension; or the fourth indication information may be multiple bits, used to indicate a synchronization resource or a control resource set. The state of 0 and the state of 1 may also be used to distinguish between the two states, and this is not limited. It should be noted that the third indication information is carried and sent via a broadcast channel. At this time, the first information is a broadcast channel, and the third indication information may be 1 bit of choice information, which is beneficial to the compatibility of subsequent versions of terminals.

[0140] In addition, it should be noted that the first terminal device can receive the first information sent by the network device, and can also obtain the first information through cell search, and determine whether to access the network device according to the first indication information. The first indication information can be indicated by a bit in the MIB, and can also be indicated by a bit in the PBCH.

[0141] In addition, the bit state of the first indication information includes: the bit state in the first state set, or the bit state in the second state set; wherein the bit state in the first state set is used to indicate that the network device supports the first terminal device to access the network device; the bit state in the second state set is used to indicate that the network device does not support the first terminal device to access the network device.

[0142] In the present application, the first indication information may be indicated by 1 bit, 2 bits, or more than 2 bits, which is not specifically limited here. The following describes the scheme of indicating by 1 bit and 2 bits, including the following situations:

[0143] Case 1: The first indication information is indicated by 1 bit

[0144] The first indication information is indicated by 1 bit, so the first state set and the second state set each contain only 1 bit state, the bit state of the first state set is the first state, where the first state can be 1; the bit state of the second state set is the second state, where the second state can be 0, or the first state is 0 and the second state is 1.

[0145] Case 2: The first indication information is indicated by 2 bits

[0146] The first indication information is indicated by two bits, so the first state set and the second state set both contain one or more bit states, and there is no same bit state in the first state set and the second state set, for example, if the bit state in the first state set is {10, 11}, then the bit state in the second state set is {00, 01}; or, if the bit state in the first state set is {01, 11}, the bit state in the second state set is {00, 10}. 0 and 1 are references to the state, and the contents represented by the state can be interchanged.

[0147] Using 1 bit to indicate the first indication information can more concisely and intuitively indicate whether the first terminal device is supported to access the network device; using 2 bits to indicate the first indication information can indicate more information, such as resource information, and / or whether the second terminal device is supported to access the network device, while indicating whether the first terminal device is supported to access the network device.

[0148] In addition, the first information also includes: second indication information, which is not applied to the first terminal device, but can be used to indicate whether the network device supports the second terminal device to access the network device. For example, the second indication information can be the information indicated by the cellBarred field in the MIB. The bit state of the cellBarred field can be a third state or a fourth state, and one possibility is that the third state and the fourth state are used to indicate whether the network device supports the first terminal device to access the network device. One possibility is that the third state is used to indicate that the network device supports the second terminal device to access the network device, and the fourth state is used to indicate that the network device does not support the second terminal device to access the network device. The third state is 0, the fourth state is 1, or the third state is 1 and the fourth state is 0.

[0149] For example, the first indication information and the second indication information may jointly indicate whether the first terminal device is supported to access the network device, or the first indication information and the second indication information may jointly indicate whether the first terminal device and the second terminal device are supported to access the network device. For example, the first indication information is 1 bit, and the cellBarred field is 1 bit, which may include the following situations:

[0150] Case 1: The bit state of the first indication information is the bit state in the first state set, and the bit state of the second indication information is the third state. At this time, the network device supports the first terminal device to access the network device; or, the first indication information is 1 bit, the cellBarred field is 1 bit, the bit state of the first indication information is the bit state in the first state set, and the bit state of the second indication information is the third state. At this time, the network device supports the first terminal device to access the network device, and the network device supports the second terminal device to access the network device.

[0151] Case 2: The bit state of the first indication information is a bit state in the first state set, and the bit state of the second indication information is the fourth state, and the network device supports the first terminal device to access the network device; or, the bit state of the first indication information is a bit state in the first state set, and the bit state of the second indication information is the third state, at this time, the network device supports the first terminal device to access the network device, and the network device does not support the second terminal device to access the network device.

[0152] Case 3: The bit state of the first indication information is a bit state in the second state set, the bit state of the second indication information is the third state, and the network device does not support the first terminal device accessing the network device; or, the bit state of the first indication information is a bit state in the second state set, and the bit state of the second indication information is the third state. At this time, the network device does not support the first terminal device accessing the network device, and the network device supports the second terminal device accessing the network device.

[0153] Case 4: the bit state of the first indication information is a bit state in the second state set, the bit state of the second indication information is the fourth state, and the network device does not support the first terminal device to access the network device; or, the bit state of the first indication information is a bit state in the second state set, and the bit state of the second indication information is the fourth state. At this time, the network device does not support the first terminal device to access the network device, and the network device does not support the second terminal device to access the network device.

[0154] Exemplarily, the first indication information may also independently indicate whether the first terminal device is supported to access the network device; or, the first indication information may independently indicate whether the first terminal device and the second terminal device are supported to access the network device. The bit state in the first state set is {10, 11} or {01, 11}, and the network device supports the first terminal device to access the network device; or, the bit state in the first state set is {10, 11} or {01, 11}, and the network device supports the first terminal device to access the network device; and / or, the bit state in the second state set is {00, 01} or {00, 10}, and the network device does not support the first terminal device to access the network device; and / or, the first state set and the second state set do not have the same state. On the basis of the above, further, the content of the bit state can be interchangeable, which is not limited here. For example, the first indication information is 2 bits, which may include the following situations:

[0155] Case 1: the bit state of the first indication information is 00, and the network device does not support the first terminal device to access the network device; or, the bit state of the first indication information is 00, the network device does not support the first terminal device to access the network device, and the network device does not support the second terminal device to access the network device.

[0156] Case 2: the bit state of the first indication information is 01, and the network device does not support the first terminal device to access the network device; or, the bit state of the first indication information is 01, and the network device does not support the first terminal device to access the network device, and the network device supports the second terminal device to access the network device.

[0157] Case 3: the bit state of the first indication information is 10, and the network device supports the first terminal device to access the network device; or, the bit state of the first indication information is 10, the network device supports the first terminal device to access the network device, and the network device does not support the second terminal device to access the network device.

[0158] Case 4: the bit state of the first indication information is 11, and the network device supports the first terminal device to access the network device; or, the bit state of the first indication information is 11, the network device supports the first terminal device to access the network device, and the network device supports the second terminal device to access the network device.

[0159] Next, the network device can indicate the access mode of the first terminal device to the network device through the first indication information and the second indication information, or can indicate separately, which can be divided into the following three situations. It should be noted that the first terminal device can obtain the corresponding association information by reading the access mode.

[0160] Exemplarily, the associated information of the access method includes one or more of the following: synchronization resource information, control resource set information, access resource information, system resource block information, data channel resource information, aggregation level information supported by the control resource set, control channel resource information, control channel symbol number information, search space configuration information, first channel repetition number information, uplink bandwidth part information, downlink bandwidth part information. Among them, the first channel may be PDCCH, PUCCH, PDSCH, PUSCH, which is not specifically limited here. The resource occupancy of the first terminal device can be obtained through the above-mentioned resource control information.

[0161] Information on synchronization resources: including the time domain resource location, frequency domain resource location, and resource index of SSB. When the first terminal device accesses the network device, it uses a different SSB from the second terminal device to access the network device, which is beneficial to load balancing. Alternatively, when the first feature of the first terminal device is different from the first feature of the second terminal device, for example, when the channel bandwidth supported by the first terminal device is smaller than that of the second terminal device, the first terminal device cannot use the same SSB as the second terminal device to access the network device, and a dedicated SSB is required.

[0162] Information of the control resource set: including the time domain resource location, frequency domain resource location, resource index, number of resource units, and one or more of the bandwidths of the CORESET, such as the number of resource units of CORESET#0. In CORESET#0, the UE performs blind detection on the PDCCH, which is used to schedule the PDSCH carrying SIB1.

[0163] The information on access resources includes one or more of the time domain resource position, frequency domain resource position, resource index, number of resource units, bandwidth, sequence transmission period, and mapping relationship with SSB of random access resources, or one or more of the time domain resource position, frequency domain resource position, resource index, number of resource units, and bandwidth of initial access resources.

[0164] Information of the system information block: including whether the system information block is shared.

[0165] Information on data channel resources: including one or more of time domain resource location, frequency domain resource location, resource index, number of resource units, bandwidth, and whether shared, for example, the data channel is a data channel carrying SIB1.

[0166] Information on the aggregation level supported by the control resource set: specifically, the CCE aggregation level supported by the control resource set. Supporting a larger aggregation level can improve the reception performance of the control channel. The first terminal device and the second terminal device can be configured with different maximum aggregation levels supported by the control resource set.

[0167] Information on control channel resources: associated with the channel bandwidth and / or SCS supported by the first terminal device, and based on the channel bandwidth, a larger number of resource units is selected as much as possible. The number of resource units of the control channel of the first terminal device is greater than the number of resource units of the control channel of the second terminal device.

[0168] Information on the number of symbols of the control channel: The number of symbols of the control channel is associated with the control resource and the supported aggregation level. An increase in the number of symbols of the control channel is conducive to an increase in the aggregation level. The number of control channel symbols of the first terminal device is greater than that of the second terminal device.

[0169] Information about search space configuration: The search space configuration of the control channel of the first terminal device may be different from the search space configuration of the second terminal device. For example, the detection period of the search space is different, the number of search spaces in each time unit, and the time position of monitoring the downlink control channel in each time unit.

[0170] Information about the number of repetitions of the first channel: The number of repetitions of the first channel sent or received by the first terminal device can be explicitly or implicitly configured. Multiple repetitions of the first channel can improve the performance of the first channel and facilitate decoding.

[0171] Information of uplink BWP: time domain resource position, frequency domain resource position, resource index, number of resource units, one or more of bandwidth of initial uplink BWP, or time domain resource position, frequency domain resource position, resource index, number of resource units, one or more of bandwidth of uplink activated BWP.

[0172] Downlink BWP information: including the time domain resource position, frequency domain resource position, resource index, number of resource units, bandwidth or more of the initial uplink BWP, or the time domain resource position, frequency domain resource position, resource index, number of resource units, bandwidth or more of the downlink activated BWP.

[0173] It should be noted that the bit state of the first indication information, and / or the bit state of the second indication information is used to indicate the access method of the first terminal device to the network device; for the same associated information, different access methods have different associated information formats. Different access methods correspond to different associated information formats, which can be understood as different content of the same associated information. For example, the associated information is the information of the control resource set. The control resource set for accessing the network device using the first access method is a configured time-frequency resource CORESET#0, and the control resource set for accessing the network device using the second access method is a resource set with a time domain offset relative to CORESET#0. The access method can be a shared access method, or an independent access method, or the access method corresponds to the associated information. In this way, while indicating whether the first terminal device is supported to access the network device, the associated information can be indicated, so that the resources used by the first terminal device to access the network device can be flexibly indicated.

[0174] For example, the way in which the first terminal device accesses the network device includes a first access method and a second access method. Among them, the format of the information associated with the first access method is different from the format of the information associated with the second access method. For example, the format of the associated information can be one or more of the time domain position information, frequency domain position information, code domain position information, resource index, time domain resource offset, frequency domain resource offset, code domain resource offset, power configuration, and beam resource of the associated information. For example, the associated information of the access method of the access network device is control channel resource information, and the control channel resource information can be a control resource set. The format of the information associated with the first access method is different from the format of the information associated with the second access method, and the time domain resources of the control resource set associated by the two access methods are different. In the first access method, the control resource sets of the first terminal device and the second terminal device are the same, and in the second access method, the control resource sets of the first terminal device and the second terminal device are independent of each other.

[0175] Case 1: The access mode of the first terminal device is jointly indicated by the first indication information and the second indication information.

[0176] Among them, when the first indication information is a bit state in the first state set and the bit state of the second indication information is a third state, the network device supports both the first terminal device and the second terminal device to access the network device, and the access mode of the first terminal device and the second terminal device shows that the first terminal device and the second terminal device share control channel resources, which can be understood as control channel resources in the same format as the second terminal device, and the associated information format can be one or more of the time domain position information, frequency domain position information, code domain position information, resource index, time domain resource offset, frequency domain resource offset, code domain resource offset, power configuration, and beam resource of the associated information. When the first indication information is a bit state in the first state set and the bit state of the second indication information is a third state, the network device supports the first terminal device to access the network device, but does not support the second terminal device to access the network device. The network device indicates that the control channel resource of the first terminal device is a dedicated resource according to the access state of the first terminal device, which can be understood as control channel resources in a different format from the second terminal device, and the associated information format can be one or more of the time domain position information, frequency domain position information, code domain position information, resource index, time domain resource offset, frequency domain resource offset, code domain resource offset, power configuration, and beam resource of the associated information. When the bit state information of the first indication information is the bit state of the second state set, and the bit state information of the second indication information is the third state, the network device does not support the first terminal device accessing the network device, and supports the second terminal device accessing the network device. When the bit state information of the first indication information is the bit state of the second state set, and the bit state information of the second indication information is the fourth state, the network device does not support the first terminal device and the second terminal device accessing the network device. The following Table 2 only takes the associated information as the control channel resource as an example. In actual application, it is not limited to which specific information the associated information is. It can be one or more of the information of the synchronization resource, the information of the control resource set, the information of the access resource, the information of the system resource block, the information of the data channel resource, etc., which are not listed one by one here, and the associated format of the associated information is not specifically limited for the same associated information.

[0177] In order to more clearly illustrate the solution for situation 1, please refer to Table 2, wherein in Table 2, the first indication information is indicated by 1 bit, the bit state of the first state set is 1, and the bit state of the second state set is 0; 1 represents the third state, 0 represents the fourth state, N represents that the access network device is not supported, and Y represents that the access network device is supported.

[0180] Case 2: Indicating the access mode of the first terminal device through the first indication information.

[0181] The following description only takes the associated information as control channel resources as an example. In actual application, it is not limited to which specific information the associated information is. It can be one or more of the following: synchronization resource information, control resource set information, access resource information, system resource block information, data channel resource information, etc., which are not listed one by one here, and the associated format of the associated information is not specifically limited for the same associated information.

[0182] The first indication information is 1 bit. When the first indication information is a bit state in the first state set, the network device supports the first terminal device to access the network device; when the first indication information is a bit state in the second state set, the network device does not support the first terminal device to access the network device. And when the first indication information is a bit state in the first state set, the network device supports the first terminal device to access the network device, and uses shared control channel resources, which can be understood as using CORESET#0, or as using the same control channel resources as the second terminal device.

[0183] The first indication information is 2 bits, and the network device supports the first terminal device to access the network device. The bit state of the first indication information includes a first state set and a second state set. The bit states in the first state set include: {10, 11}, and the second state set includes {00, 01}. The bit state in the first state set indicates that the first terminal device is supported to access the network device, and the bit state in the second state set indicates that the first terminal device is not supported to access the network device. At the same time, the bit state of the first indication information can also indicate the way in which the first terminal device accesses the network device. The associated information of the way to access the network device can be a control channel resource. For example, when the network device supports the first terminal device to access the network device, 10 indicates that the control channel resource of the first terminal device is a dedicated resource, which can be understood as a control channel resource in a different format from that of the second terminal device. The associated information format can be one or more of the time domain position information, frequency domain position information, code domain position information, resource index, time domain resource offset, frequency domain resource offset, code domain resource offset, power configuration, and beam resource of the associated information. For example, when the network device supports the first terminal device to access the network device, 11 indicates that the control channel resources of the first terminal device are shared resources, which can be understood as control channel resources using the same format as the second terminal device, and the associated information format can be one or more of the time domain position information, frequency domain position information, code domain position information, resource index, time domain resource offset, frequency domain resource offset, code domain resource offset, power configuration, and beam resources of the associated information.

[0184] Alternatively, the network device supports the first terminal device to access the network device, and the bit state of the first indication information includes a first state set and a second state set. The bit states in the first state set include: {01, 11}, and the second state set includes {00, 10}. The bit state in the first state set indicates that the first terminal device is supported to access the network device, and the bit state in the second state set indicates that the first terminal device is not supported to access the network device. At the same time, the bit state of the first indication information can also indicate the way in which the first terminal device accesses the network device, and the information associated with the way of accessing the network device can be a control channel resource. For example, in the case where the network device supports the first terminal device to access the network device, 01 indicates that the control channel resource of the first terminal device is a dedicated resource, which can be understood as a control channel resource in a different format from that of the second terminal device, and the associated information format can be one or more of the time domain position information, frequency domain position information, code domain position information, resource index, time domain resource offset, frequency domain resource offset, code domain resource offset, power configuration, and beam resource of the associated information. For example, when the network device supports the first terminal device to access the network device, 11 indicates that the control channel resources of the first terminal device are shared resources, which can be understood as control channel resources using the same format as the second terminal device, and the associated information format can be one or more of the time domain position information, frequency domain position information, code domain position information, resource index, time domain resource offset, frequency domain resource offset, code domain resource offset, power configuration, and beam resources of the associated information.

[0185] In the case where the network device supports the first terminal device to access the network device, the method of accessing the network device by the first terminal device is indicated more flexibly, and the associated information formats of different access methods are different, which can more flexibly indicate the resources of the access network device.

[0186] Case 3: Indicating the access mode of the first terminal device through the second indication information.

[0187] The following description only takes the associated information as control channel resources as an example. In actual application, it is not limited to which specific information the associated information is. It can be one or more of the following: synchronization resource information, control resource set information, access resource information, system resource block information, data channel resource information, etc., which are not listed one by one here, and the associated format of the associated information is not specifically limited for the same associated information.

[0188] The second indication information is 1 bit. When the second indication information is a bit state in the first state set, the network device supports the first terminal device to access the network device; when the second indication information is a bit state in the second state set, the network device does not support the first terminal device to access the network device. And when the second indication information is a bit state in the first state set, the network device supports the first terminal device to access the network device, and uses shared control channel resources, which can be understood as using CORESET#0, or as using the same control channel resources as the second terminal device.

[0189] The second indication information is 2 bits, the network device supports the first terminal device to access the network device, the bit state of the second indication information includes a first state set and a second state set, the bit states in the first state set include: {10, 11}, the second state set includes {00, 01}, the bit state in the first state set indicates that the first terminal device is supported to access the network device, and the bit state in the second state set indicates that the first terminal device is not supported to access the network device, and the bit state of the second indication information can also indicate the way the first terminal device accesses the network device, and the information associated with the way of accessing the network device can be a control channel resource. For example, in the case where the network device supports the first terminal device to access the network device, 10 indicates that the control channel resource of the first terminal device is a dedicated resource, which can be understood as a control channel resource in a different format from that of the second terminal device, and the associated information format can be one or more of the time domain position information, frequency domain position information, code domain position information, resource index, time domain resource offset, frequency domain resource offset, code domain resource offset, power configuration, and beam resource of the associated information. For example, when the network device supports the first terminal device to access the network device, 11 indicates that the control channel resources of the first terminal device are shared resources, which can be understood as control channel resources using the same format as the second terminal device, and the associated information format can be one or more of the time domain position information, frequency domain position information, code domain position information, resource index, time domain resource offset, frequency domain resource offset, code domain resource offset, power configuration, and beam resources of the associated information.

[0190] Alternatively, the network device supports the first terminal device to access the network device, and the bit state of the second indication information includes a first state set and a second state set. The bit states in the first state set include: {01, 11}, and the second state set includes {00, 10}. The bit state in the first state set indicates that the first terminal device is supported to access the network device, and the bit state in the second state set indicates that the first terminal device is not supported to access the network device. At the same time, the bit state of the second indication information can also indicate the way in which the first terminal device accesses the network device, and the information associated with the way of accessing the network device can be a control channel resource. For example, in the case where the network device supports the first terminal device to access the network device, 01 indicates that the control channel resource of the first terminal device is a dedicated resource, which can be understood as a control channel resource in a different format from that of the second terminal device, and the associated information format can be one or more of the time domain position information, frequency domain position information, code domain position information, resource index, time domain resource offset, frequency domain resource offset, code domain resource offset, power configuration, and beam resource of the associated information. For example, when the network device supports the first terminal device to access the network device, 11 indicates that the control channel resources of the first terminal device are shared resources, which can be understood as control channel resources using the same format as the second terminal device, and the associated information format can be one or more of the time domain position information, frequency domain position information, code domain position information, resource index, time domain resource offset, frequency domain resource offset, code domain resource offset, power configuration, and beam resources of the associated information.

[0191] In the case where the network device supports the first terminal device to access the network device, the method of accessing the network device by the first terminal device is indicated more flexibly, and the associated information formats of different access methods are different, which can more flexibly indicate the resources of the access network device.

[0192] In addition, it should be noted that the first information can also directly indicate the control resource status through MIB, or SIB, or downlink control information, wherein the MIB or downlink control information or SIB includes a first parameter, and the first parameter is one or more of the following parameters: information on the synchronization resources of the first terminal device, information on the aggregation level supported by the control resource set, information on the number of symbols of the control channel, information on the resource units of the control channel, information on the search space configuration, and information on the number of repetitions of the first channel. It should be noted that the first parameter can be the pdcch-ConfigSIB1 field in the MIB. The information indicated by the pdcch-ConfigSIB1 field can be interpreted differently by the first terminal device and the second terminal device, that is, the parameters contained in the first parameter can be different.

[0193] If the control resource is CORESET, the device performance of the first terminal device (REDCAP UE) is worse than that of the second terminal device (legacy UE), and the signal receiving capability of the first terminal device is limited, so the network device needs to send a first channel with a larger aggregation level, such as PDCCH. For PDCCH, when the downlink channel quality of the terminal device is good or the coverage of the downlink channel is large, the network device can send a PDCCH with a smaller aggregation level. When the downlink channel quality of the terminal device is poor or the coverage of the downlink channel is small, the network device can send a PDCCH with a larger aggregation level. The first terminal device can also demodulate the first channel by sending the first channel multiple times. Alternatively, the maximum aggregation level supported by CORESET can be increased and the number of repetitions of the first channel can be increased so that the first terminal device can better demodulate the first channel.

[0194] Method 1: By increasing the CORESET aggregation level, the first terminal device can better demodulate the first channel

[0195] In order for the first terminal device to receive communication services in the network device, the first channel can be demodulated, and a channel with a larger aggregation level is required. When the network device serves the legacy UE, the aggregation levels of CORESET usually include 1, 2, 4, 8, and 16. In the present application, in order for the network device to provide services to the first terminal device, the aggregation level of CORESET in the present application is greater than or equal to the first threshold, and the first threshold usually includes 8*n, where n is a positive integer greater than or equal to 1, such as the first threshold value is 16 or 32, or other values, which are not specifically limited here. The value of the first threshold is 32, which can better guarantee the performance of the downlink control channel.

[0196] According to the above description, it can be known that the method for determining the aggregation level of CORESET can be obtained by dividing (the number of RBs of CORESET * the number of symbols of CORESET) by 6. According to the above, in order to obtain a larger aggregation level of CORESET, it can be achieved by increasing the number of RBs of CORESET or the number of symbols of CORESET, or by increasing the number of RBs of CORESET and the number of symbols of CORESET at the same time. When increasing the number of RBs of CORESET, it can be understood that, under a certain SCS and bandwidth, based on the maximum configurable number of RBs, as many RBs as possible are configured for the first terminal device, or, it can be achieved by adopting a smaller SCS to obtain a larger number of configurable RBs. The value of the number of symbols of CORESET is greater than or equal to the second threshold, and the second threshold is usually 3, 4, 6, 9, 12, or other values.

[0197] For example, when the bandwidth is 20M, the SCS of PDCCH is 60KHz, and the number of symbols is 4 or 6; when the bandwidth is 10M, the SCS of PDCCH is 30KHz, and the number of symbols is 4; when the bandwidth is 10M, the SCS of PDCCH is 60KHz, and the number of symbols is 9; when the bandwidth is 10M, the SCS of PDCCH is 60KHz, and the number of symbols is 12. Or simply put, when the bandwidth is 20M, the symbol length increases to 6, and when the bandwidth is 10M, the symbol length increases to 12. Such a configuration can ensure that the complexity is low during interleaving mapping, and better frequency domain diversity gain can be obtained. The number of symbols of CORESET can also be any value greater than the threshold according to the threshold, such as 3, 4, 6, 9, 12, etc. Such a configuration can ensure that the complexity is low during interleaving mapping, and better frequency domain diversity gain can be obtained. In practical applications, the SCS of SSB and PDCCH can also be considered at the same time.

[0198] In specific implementation, the aggregation level of CORESET can be increased through the following three situations. It should be noted that the method for increasing the aggregation level of CORESET (including the following situations 1, 2, and 3) can be pre-configured through high-level signaling, such as RRC signaling or MAC CE; can be pre-defined, such as defined in the form of a table in the protocol, and then use signaling to indicate the configuration to be used, or can be indicated by implicit association; can be pre-configured through high-level signaling, such as RRC signaling or MAC CE, and then indicated through physical layer signaling, such as downlink control information (DCI).

[0199] Case 1: Increase the aggregation level of CORESET by increasing the number of CORESET symbols

[0200] It should be noted that the network device increases the number of symbols of CORESET to increase the aggregation level of CORESET, which can be reflected in the form of a table. The field pdcch-ConfigSIB1 in the MIB corresponds to Table 3 of the first terminal device CORESET. In Table 3, the SCS of SSB is 30KHz, and the SCS of PDCCH is 30KHz. For 10M bandwidth, the first terminal device is indicated by adding indexes (Index) Index5~9. Compared with indexes 0-4, the number of symbols of CORESET is significantly increased. For 20M bandwidth, Index14~15 are added to indicate the first terminal device. In actual application, only one or more rows in Table 3 are applied, which is not specifically limited here. The number of RBs of CORESET corresponding to Index8 in Table 3 is 24, and the number of symbols of CORESET is 8, so the aggregation level of CORESET is 32 (24*8 / 6), so the network device can provide communication services for the first terminal device. The information in other rows is not listed one by one here. In Table 3, SS / PBCH block (SSB) and CORESET multiplexing pattern indicate the multiplexing method of SSB and CORESET; Offset indicates the frequency domain offset of SSB and CORESET.

[0201] Table 3

[0202]

[0203]

[0204] Case 2: Increase the aggregation level of CORESET by increasing the number of RBs in CORESET

[0205] In the present application, it is considered that when the SCS of the PDCCH is determined, or the SCS of the PDCCH and the SCS of the SSB are determined, and the bandwidth of the first terminal device is determined, more RBs are configured within the range of the maximum number of RBs of the CORESET as much as possible. For example, when the bandwidth of the first terminal device is 10MHz and the SCS of the PDCCH is 30KHz, or when the bandwidth of the first terminal device is 10MHz, the SCS of the PDCCH is 30KHz, and the SCS of the SSB is 30KHz, 24 RBs are configured; or when the bandwidth of the first terminal device is 20MHz, the SCS of the PDCCH is 30KHz, and the SCS of the SSB is 30KHz, 48 RBs are configured.

[0206] Case 3: Increase the aggregation level of CORESET by increasing the number of RBs and symbols of CORESET

[0207] The present application increases the number of RBs of CORESET and / or increases the number of symbols of CORESET so that the maximum aggregation level supported by CORESET is 16 or 32. The maximum aggregation level supported by CORESET is 16 or 32, which can achieve a lower channel code rate, improve the demodulation of the PDCCH channel by the first terminal device, reduce interference, improve the control channel signal-to-noise ratio, and improve the coverage of PDCCH.

[0208] Method 2: By increasing the number of repetitions of the first channel, the first terminal device can better send or receive the first channel

[0209] It should be noted that the number of repetitions of the first channel is associated with at least one of the information on the aggregation level supported by the control resource set, the information on the resource unit of the control channel, the number of symbols of the control channel, and the information on the search space configuration.

[0210] It should be noted that the method of increasing the number of repetitions of the first channel (including the following situations 1, 2, and 3) can be pre-configured through high-level signaling, such as RRC signaling or MAC CE; it can be pre-defined, for example, defined in the form of a table in the protocol, and then signaling is used to indicate the configuration to be used, or it can be indicated in an implicitly associated manner; it can be pre-configured through high-level signaling, such as RRC signaling or MAC CE, and then indicated through physical layer signaling, such as DCI.

[0211] In one example, the number of repetitions of the first channel may be determined according to one or more of the maximum aggregation level supported by the CORESET, the number of RBs of the CORESET, the number of symbols, or the listening opportunities of the first channel, and the number of search space (SS) sets. The number of repetitions of the first channel may be implicitly associated with the maximum aggregation level supported by the CORESET, the number of RBs of the CORESET, the number of symbols, or the listening opportunities of the first channel, and the number of search space (SS) sets, or may be indicated by display. The display method may be that the displayed signaling indicates the number of repetitions of the first channel separately, for example, the base station displays the number of repetitions of the first channel through physical layer signaling or high-layer signaling based on the above information. The display method may also be to add the number of repetitions of the first channel in the table, in which case the configuration of the number of repetitions of the first channel is associated with other information in the table. Whether the network device increases the number of repetitions of the first channel through implicit association or explicit association can be indicated by a column in the table, and the numerical value of the number of repetitions of the first channel determined by explicit association and implicit association is consistent, but the explicit association is reflected by a column in the table, and the implicit association is not directly reflected in the table.

[0212] It should be noted that the number of repetitions of the first channel is determined according to the number of search space sets in each time slot. The more the number of search space sets, the greater the number of repetitions, as shown in Table 4 below. The greater the number of search space sets per slot, the greater the number of repetitions, which is beneficial to increasing the uplink coverage, or the downlink coverage or spectrum efficiency. Alternatively, the smaller the number of search space sets in each time slot, the greater the number of repetitions. Since the first channel has fewer transmission opportunities, increasing the number of repetitions of the first channel is beneficial to the transmission or reception of the first channel, increasing the uplink coverage, or the downlink coverage or spectrum efficiency. For example, the number of repetitions can be any number greater than 2, and in particular can be a power of 2. For example, the number of search space sets is n, n is a positive integer, the number of repetitions is m, and the number of search space sets is 2n, then the number of repetitions can be 2m or m / 2. The number of repetitions of the first channel can be determined according to the maximum aggregation level supported by the CORESET. For example, the greater the maximum aggregation level supported by the CORESET, the greater the number of repetitions of the first channel, or the greater the maximum aggregation level supported by the CORESET, the smaller the number of repetitions of the first channel. The number of repetitions of the first channel can be 2n, or 2 to the power of n, or 3n, or 3 to the power of n, where n is a positive integer. For example, the maximum aggregation level supported by CORESET is 32, and the number of repetitions of the first channel is 4 or 8. The maximum aggregation level supported by CORESET is 16, and the number of repetitions of the first channel is 2 or 4. The maximum aggregation level supported by CORESET is 8, and the number of repetitions of the first channel is 1 or 2. For example, the maximum aggregation level supported by CORESET is 32, and the number of repetitions of the first channel is 1 or 2. The maximum aggregation level supported by CORESET is 16, and the number of repetitions of the first channel is 2 or 4. The maximum aggregation level supported by CORESET is 8, and the number of repetitions of the first channel is 4 or 8.

[0213] In Table 4, O represents the offset of the starting time slot of SS#0 relative to slot0 in the wireless frame, M and Number of searchspace sets per slot are the number of search space#0 in a time slot, and First symbol index is the symbol position of the first search space#0. Table 5 adds a row to Table 4 to indicate the number of repetitions of the first channel, such as: the number of repetitions of the first channel corresponding to Index2 is m. Table 6 shows whether the association method is implicit association or explicit association. The specific meanings of the parameters in Tables 4 and 5 are not illustrated one by one again. In actual application, only certain rows or columns in Table 4 or Table 5 are applied, and no specific limitation is made here.

[0223] If the number of repetitions of the first channel is determined based on the maximum aggregation level supported by CORESET, the number of RBs and the number of symbols of CORESET, a column can be added to the configuration table of CORESET to indicate the number of repetitions, as shown in Table 7 below. In Table 7, SS / PBCH block (SSB) and CORESET multiplexing pattern indicate the multiplexing method of SSB and CORESET; Offset indicates the frequency domain offset of SSB and CORESET. For example, the number of repetitions of the first channel corresponding to Index 1 is 4. The meaning of each row of data in Table 7 is not explained one by one here.

[0224] Table 7

[0225]

[0226] Although the number of repetitions of the first channel can be determined intuitively through Table 7, adding one column will inevitably increase the signaling overhead. In order to reduce the signaling overhead, the number of repetitions can also be directly indicated by the network device without adding a column for indicating the number of repetitions of the first channel, such as Index0-4, the network device indicates that the number of repetitions of the first channel is 4; Index10-13, the network device indicates that the number of repetitions of the first channel is 2.

[0227] Method 3: By increasing the number of CORESET symbols and the number of repetitions of the first channel, the first terminal device can demodulate the first channel

[0228] For example, during execution, one column can be added on the basis of Table 3 to indicate the number of repetitions of the first channel, or it can be indicated directly through the network device. Here, it can be indicated in Table 8, where SS / PBCH block (SSB) and CORESET multiplexing pattern indicate the multiplexing mode of SSB and CORESET; Offset indicates the frequency domain offset of SSB and CORESET. The number of repetitions of the first channel corresponding to Index 8 in Table 8 is 2. On the basis of the aggregation level of CORESET being 32, the number of repetitions of the first channel is also increased, so that the first terminal device can better demodulate the first channel.

[0230]

[0231] The network device indicates whether it supports the first terminal device to access the network device through different bit states. The network device mentioned in this application supports the first terminal device to access the network device, which means that the network device has the ability to support the terminal device to access the network device, or the network device allows the terminal device to access the network device. The first indication information can be 1 bit or multiple bits. The bit state in the first state set can be 1 bit state or multiple bit states, and the bit state in the second state set can be 1 bit state or multiple bit states. Among them, the number of bits in the first state set is the same as the number of bits in the second state set, such as: if the bit state of the first state set is 1 bit, then the bit state of the second state set is also 1 bit. The prior art does not provide indication information for indicating the first terminal device to access the network device. The solution provided in this application is more suitable for the load balancing requirements when the first terminal device accesses the network device.

[0232] Based on the same inventive concept, the present application embodiment provides a communication device such as Figure 3 As shown, the communication device includes a processing unit 31 and a transceiver unit 32 .

[0233] Among them, the processing unit 31 is used to determine the first indication information, the bit state of the first indication information is a bit state in a first state set, and the network device supports the first terminal device to access the network device, and / or the bit state of the first indication information is a bit state in a second state set, and the network device does not support the first terminal device to access the network device; the transceiver unit 32 is used to send the first information, and the first information includes the first indication information.

[0234] In a possible implementation manner, the first information includes: a main information block sent by the network device.

[0235] In the present application, the first information includes a main information block, so that the network device can send the first indication information through the main information block.

[0236] In a possible implementation manner, the master information block further includes second indication information, wherein the second indication information is cellBarred information, and the cellBarred information is not applied to the first terminal device.

[0237] On the premise that the first information includes a main information block sent by the network device, the main information block also includes second indication information. The second indication information may be cellBarred information. The cellBarred information is usually not used to determine whether the network device supports access to the first terminal device.

[0238] The second indication information in the present application is not applied to the first terminal device. It can be understood that when the state of the second indication information is that the access network device is not supported, the state is invalid for the first terminal device, and independent control of whether the network device supports the first terminal device to access the network device can be achieved.

[0239] In a possible implementation manner, the first information includes: downlink control information or system information block sent by the network device.

[0240] In the present application, the first information includes downlink control information or a system information block. The system information block is carried in a downlink shared channel scheduled by the downlink control information. The network device can send the first indication information through the downlink control information or the system information block. The reserved bits in the downlink control information or the system information block, that is, the available bits are more, which is more conducive to the sending of the first indication information.

[0241] In a possible implementation, before the network device sends the first information, it also includes: the network device sends a main information block to the first terminal device; the main information block includes cellBarred information; and the cellBarred information is not applied to the first terminal device.

[0242] In the present application, the network device sends a main information block before sending the first information, and the first information is downlink control information or a system information block. Before sending the first information, the main information block has been sent, and the main information block includes cellBarred information, and the cellBarred information is not applied to the first terminal device, that is, the content indicated by the cellBarred information is invalid for the first terminal device, and independent control of whether the network device supports the first terminal device to access the network device can be achieved.

[0243] In a possible implementation manner, the network device sends third indication information for indicating a broadcast channel type;

[0244] The state of the third indication information is 0, and the first information is the MIB included in the broadcast channel; or,

[0245] The state of the third indication information is 1, and the first information includes an extended information block included in the broadcast channel;

[0246] The extended information block does not include cellBarred information, and / or the extended information block includes fourth indication information.

[0247] In the present application, the extended information block may be an information block dedicated to the first terminal device, which includes one or more bits, or one or more information, for example, the extended information block does not include cellBarred information, and the extended information block includes fourth indication information; or, the extended information block does not include cellBarred information; or, the extended information block includes fourth indication information. The fourth indication information may be 1 bit or multiple bits, for example, the fourth indication information may be 1 bit, and the 1 bit is used as a reserved bit; or the fourth indication information may be 1 bit, and one of the states of the 1 bit is used to indicate extended information, messageClassExtension; or the fourth indication information may be multiple bits, used to indicate a synchronization resource or a control resource set. The state of 0 and the state of 1 may also be used to distinguish between the two states, and this is not limited. It should be noted that the third indication information is carried and sent via a broadcast channel. In this case, the first information is a broadcast channel, and the third indication information may be 1 bit of choice information.

[0248] In a possible implementation, the first indication information is indicated by 1 bit, the bit state of the first indication information is a bit state in a first state set, the bit state of the second indication information is a third state, and the network device supports the first terminal device to access the network device; or, the bit state of the first indication information is a bit state in a first state set, the bit state of the second indication information is a fourth state, and the network device supports the first terminal device to access the network device; or, the bit state of the first indication information is a bit state in a second state set, the bit state of the second indication information is the third state, and the network device does not support the first terminal device to access the network device; or, the bit state of the first indication information is a bit state in a second state set, the bit state of the second indication information is the fourth state, and the network device does not support the first terminal device to access the network device; wherein, the third state and the fourth state include 0 and 1; the third state is different from the fourth state.

[0249] The second indication information is the third state or the fourth state, the third state includes 0 or 1, the fourth state includes 1 or 0, when the third state is 1, the fourth state is 0; when the third state is 0, the fourth state is 1. The bit state of the first state set and the second indication information can jointly indicate whether the network device supports access to the network device.

[0250] This method can more flexibly indicate the access status of the first terminal device. Compared with the prior art which does not provide indication information for indicating the first terminal device to access the network device, the solution provided by the present application is more suitable for the load balancing requirement when the first terminal device accesses the network device.

[0251] In a possible implementation, the first indication information is indicated by 2 bits, the network device supports the first terminal device to access the network device, and the bit state of the first indication information includes a first state set; the first state set includes: {10, 11} or {01, 00}; the network device does not support the first terminal device to access the network device, and the bit state of the first indication information includes: a first state set; the first state set includes: {00, 01} or {11, 10}; wherein, the first state set indicates that the network device supports the first terminal device to access the network device; the second state set indicates that the network device does not support the first terminal device to access the network device; the first state set is different from the second state set.

[0252] The first indication information is indicated by 2 bits. When the first state set is {10, 11}, the second state set is {00, 01}; when the first state set is {01, 00}, the second state set is {11, 10}. The first state set indicates that the network device supports the first terminal device to access the network device; the second state set indicates that the network device does not support the first terminal device to access the network device.

[0253] This method can more flexibly indicate the access status of the first terminal device. Compared with the prior art which does not provide indication information for indicating the first terminal device to access the network device, the solution provided by the present application is more suitable for the load balancing requirement when the first terminal device accesses the network device.

[0254] In one possible implementation, the bit state of the first indication information and / or the bit state of the second indication information are used to indicate the access method of the first terminal device to access the network device; for the same associated information, different access method associated information formats are different; the associated information of the access method includes one or more of the following: synchronization resource information, control resource set information, access resource information, system information block information, data channel resource information, aggregation level information supported by the control resource set, control channel resource information, control channel symbol number information, search space configuration information, first channel repetition number information, uplink bandwidth part information, downlink bandwidth part information.

[0255] It should be noted that the bit state of the first indication information, and / or the bit state of the second indication information can indicate the access method of the first terminal device to the network device, and different access methods correspond to different associated information formats. Different access methods correspond to different associated information formats, which can be understood as different content of the same associated information. For example, the associated information is the information of the control resource set. The control resource set for accessing the network device using the first access method is a configured time-frequency resource CORESET#0, and the control resource set for accessing the network device using the second access method is a resource set with a time domain offset relative to CORESET#0. The access method can be a shared access method, or an independent access method, or the access method corresponds to the associated information.

[0256] In addition, according to the above, the second indication information is not applied to the first terminal device, but can be applied to the second terminal device. The first characteristics of the first terminal device and the second terminal device are different, and the parameters of the first characteristic include at least one of the following: bandwidth (channel bandwidth), number of supported or configured resource units, number of transmitting antenna ports and / or number of receiving antenna ports, number of RF channels, number of HARQ processes, supported peak rate, application scenarios, latency requirements, processing capabilities, protocol version duplex mode (half-duplex, full-duplex) services (IoT applications such as video surveillance, MBB, etc.).

[0257] In addition, the synchronization resource information includes one or more of the time domain resource position, frequency domain resource position, resource index, number of resource units, bandwidth, and transmission period of the SSB. When the first terminal device accesses the network device, it uses a different SSB access from the second terminal device, which is beneficial to load balancing. Alternatively, when the first feature of the first terminal device is different from the first feature of the second terminal device, for example, when the channel bandwidth supported by the first terminal device is smaller than that of the second terminal device, the first terminal device cannot use the same SSB as the second terminal device to access the network device, and a dedicated SSB is required.

[0258] The information of the control resource set includes the time domain resource position, frequency domain resource position, resource index, number of resource units, and one or more of bandwidths of CORESET, such as the number of resource units of CORESET#0. In CORESET#0, the UE performs blind detection on the PDCCH, which is used to schedule the PDSCH carrying SIB1.

[0259] The information on access resources includes one or more of the time domain resource position, frequency domain resource position, resource index, number of resource units, bandwidth, sequence transmission period, and mapping relationship with SSB of random access resources, or one or more of the time domain resource position, frequency domain resource position, resource index, number of resource units, and bandwidth of initial access resources.

[0260] The information of the system information block includes whether the system information block is shared.

[0261] The information of the data channel resources includes one or more of the time domain resource position, the frequency domain resource position, the resource index, the number of resource units, the bandwidth, and whether they are shared. For example, the data channel is a data channel carrying SIB1.

[0262] Information on the aggregation level supported by the control resource set: specifically, the CCE aggregation level supported by the control resource set. Supporting a larger aggregation level can improve the reception performance of the control channel. The first terminal device and the second terminal device can be configured with different maximum aggregation levels supported by the control resource set.

[0263] Information on control channel resources: associated with the channel bandwidth and / or SCS supported by the first terminal device, and based on the channel bandwidth, a larger number of resource units is selected as much as possible. The number of resource units of the control channel of the first terminal device is greater than the number of resource units of the control channel of the second terminal device.

[0264] Information on the number of symbols of the control channel: The number of symbols of the control channel is associated with the control resource and the supported aggregation level. An increase in the number of symbols of the control channel is conducive to an increase in the aggregation level. The number of control channel symbols of the first terminal device is greater than that of the second terminal device.

[0265] Information about search space configuration: The search space configuration of the control channel of the first terminal device may be different from the search space configuration of the second terminal device. For example, the detection period of the search space is different, the number of search spaces in each time unit, and the time position of monitoring the downlink control channel in each time unit.

[0266] Information about the number of repetitions of the first channel: The number of repetitions of the first channel sent or received by the first terminal device can be explicitly or implicitly configured. Multiple repetitions of the first channel can improve the performance of the first channel and facilitate decoding.

[0267] The uplink BWP information includes the time domain resource position, frequency domain resource position, resource index, number of resource units, bandwidth or more of the initial uplink BWP, or the time domain resource position, frequency domain resource position, resource index, number of resource units, bandwidth or more of the uplink activated BWP.

[0268] The information of the downlink BWP includes the time domain resource position, frequency domain resource position, resource index, number of resource units, bandwidth or more of the initial uplink BWP, or the time domain resource position, frequency domain resource position, resource index, number of resource units, bandwidth or more of the downlink activated BWP.

[0269] In this way, while indicating whether the first terminal device is supported to access the network device, the associated information can be indicated, so that the resources used by the first terminal device to access the network device can be flexibly indicated.

[0270] In a possible implementation, the main information block or the downlink control information or the system information block also includes a first parameter, which includes one or more of the following parameters: information on synchronization resources of the first terminal device, information on the aggregation level supported by the control resource set, information on the number of symbols of the control channel, information on the resource unit of the control channel, information on the search space configuration, and information on the number of repetitions of the first channel.

[0271] In the present application, the first parameter can be a bit in the first information, or can be an independent field in the first new message. The information indicated in the first parameter is information dedicated to the first terminal device, which is beneficial to the performance improvement of the first terminal device. For example, a lower channel code rate can be achieved, and the decoding performance of the first terminal device for the downlink control channel can be improved, interference can be reduced, the signal-to-noise ratio of the control channel can be improved, and the coverage of the downlink control channel can be improved.

[0272] In a possible implementation, the aggregation level supported by the control resource set is greater than or equal to a first threshold; wherein the first threshold includes 8*n, and n is a positive integer greater than or equal to 1.

[0273] In the present application, increasing the aggregation level supported by the control resource set in this way is beneficial to the performance improvement of the first terminal device. For example, a lower channel code rate can be achieved, the decoding performance of the first terminal device for the downlink control channel can be improved, interference can be reduced, and the signal-to-noise ratio of the control channel can be improved.

[0274] In a possible implementation manner, the number of symbols in the symbol number information of the control channel is greater than or equal to a second threshold, where the second threshold includes 3 or 4.

[0275] In the present application, increasing the aggregation level supported by the control resource set in this way is beneficial to the performance improvement of the first terminal device. For example, a lower channel code rate can be achieved, the decoding performance of the first terminal device for the downlink control channel can be improved, interference can be reduced, and the signal-to-noise ratio of the control channel can be improved.

[0276] In a possible implementation, the number of repetitions of the first channel is associated with at least one of information on an aggregation level supported by a control resource set, information on a resource unit of a control channel, the number of symbols of the control channel, and information on a search space configuration.

[0277] In the present application, the first parameter can be a bit in the first information, or can be an independent field in the first new message. The information indicated in the first parameter is information dedicated to the first terminal device, which is beneficial to the performance improvement of the first terminal device. For example, a lower channel code rate can be achieved, and the decoding performance of the first terminal device for the downlink control channel can be improved, interference can be reduced, the signal-to-noise ratio of the control channel can be improved, and the coverage of the downlink control channel can be improved.

[0278] The present application embodiment provides a communication device such as Figure 4 As shown, the communication device includes a transceiver unit 41 and a processing unit 42 .

[0280] The network device indicates whether to instruct the first terminal device to access the network device through different bit states. Compared with the prior art that does not provide indication information for instructing the first terminal device to access the network device, the solution provided by the present application is more adapted to the needs of the first terminal device.

Among them, the number of bits in the first state set is the same as the number of bits in the second state set, such as: if the bit state of the first state set is 1 bit, then the bit state of the second state set is also 1 bit. The prior art does not provide indication information for indicating the first terminal device to access the network device.
