[0045] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

[0046] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

[0047] With the pursuit of speed, latency, high-speed mobility, energy efficiency and the diversity and complexity of services in future life, the Third Generation Partnership Project (3GPP) rdThe 3rd Generation Partnership Project (3GPP) international standard organization has begun to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC).

[0048] On the one hand, eMBB still aims at users to obtain multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary greatly, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), traffic safety, etc. Typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low cost and long service life of modules, etc.

[0049] In order to reduce air interface signaling and quickly restore wireless connections and data services, 5G defines a new Radio Resource Control (RRC) state, namely the RRC inactive (RRC_INACTIVE) state. This state is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state.

[0050] 1) RRC_IDLE state (abbreviated as idle state): Mobility is based on cell selection and reselection of terminal equipment, paging is initiated by the core network (CN), and the paging area is configured by the CN. There is no terminal equipment context on the base station side, and there is no RRC connection.

[0051] 2) RRC_CONNECTED state (referred to as connected state): There is an RRC connection, and there is a terminal device context on the base station side and the terminal device side. The network side knows the location of the terminal device at the specific cell level. The mobility is the mobility controlled by the network side. Unicast data can be transmitted between the terminal device and the base station.

[0052] 3) RRC_INACTIVE state (abbreviated as inactive state): Mobility is based on cell selection reselection of the terminal device, there is a connection between CN-NR, the terminal device context exists on a certain base station, paging is triggered by RAN, and the paging area based on RAN is managed by RAN. The network side knows the location of the terminal device based on the paging area level of RAN.

[0053] NR R17 introduces NR-light terminal devices, which mainly have the following three scenarios:

[0054] Industrial Wireless Sensors: Compared with URLLC type terminal devices, industrial wireless sensors have relatively low latency and reliability requirements. At the same time, the cost and power consumption of industrial wireless sensors are also lower than those of URLLC type terminal devices and eMBB type terminal devices.

[0055] Video surveillance: mainly used in video surveillance scenarios such as smart cities and industrial factories. The data collection and processing in smart cities facilitates more effective monitoring and control of urban resources and provides more effective services to urban residents.

[0056] Wearables: including smart watches, electronic health devices, and some medical monitoring devices. One common feature of these devices is their small size.

[0057] The common requirements of the above three scenarios are: 1) NR-light type terminal equipment requires lower equipment cost and complexity compared with R15 / 16 eMBB type terminal equipment. The basic consensus is to reduce bandwidth and receiving antenna. 2) NR-light type terminal equipment is relatively small in size. 3) NR-light type terminal equipment is required to achieve coverage equivalent to R15 / 16 eMBB type terminal equipment. If the coverage loss caused by reducing the receiving antenna, reducing the bandwidth, reducing the power level or other reductions in the complexity of the terminal equipment needs to be compensated.

[0058] For the above three scenarios, each scenario has the following individual requirements: 1) The reliability requirement of industrial wireless sensors is 99.99%, and the end-to-end latency requirement is 100ms. The bit rate requirement is 2Mbps. The device is stationary. The battery life is several years. For security-related sensors, the latency requirement is 5-10ms. 2) The bit rate requirement for video surveillance is 2-4Mbps, the latency requirement is less than 500ms, and the reliability requirement is 99-99.9%. For some high-end videos, the rate requirement is 2-4Mbps. The uplink traffic is relatively large. 3) Wearable devices can refer to LTE Cat 4, with a rate requirement of 150Mbps / 50Mbps.

[0059] It should be noted that the NR-light type terminal devices mentioned in this application generally refer to those low-capability terminal devices or terminal devices with special applications.

[0060] Due to the introduction of NR-light type terminal devices, it is necessary to consider the compatibility of NR cells with NR-light type terminal devices, while not affecting the access of traditional terminal devices (such as eMBB type terminal devices) to NR cells. To this end, it is necessary to consider how to take into account the needs of traditional terminal devices and NR-light type terminal devices to access NR cells. Considering the demand of NR-light type terminal devices for low bandwidth, it is necessary to design different types of cell bandwidths, especially different designs for transmission bandwidth for public resources and public information transmission. Furthermore, the capabilities supported by NR-light type terminal devices are relatively low, such as the supported transport block size (Transport Block size, TB size) or modulation and coding scheme (Modulation and Coding Scheme, MCS) is relatively low, the number of supported transmissions (RX) is relatively low, and so on. The capability reporting of the terminal device requires the terminal device to enter the connected state and the AS to be securely activated before it can be reported. Therefore, in order to be compatible with traditional NR terminal devices and NR light type terminal devices, or different NR-light type terminal devices, the normal residence in the NR cell, the reception of public messages, and the initial access to the cell, etc., a solution is required. To this end, the following technical solutions of the embodiments of the present application are proposed.

[0061] Figure 2 is a flow chart of the BWP configuration method provided in the embodiment of the present application, such as Figure 2 As shown, the BWP configuration method includes the following steps:

[0062] Step 201: A terminal device receives first configuration information sent by a network device, where the first configuration information includes multiple initial BWP configuration information, each of which is associated with a terminal type and / or terminal capability.

[0063] In an embodiment of the present application, the network device sends the first configuration information to the terminal device, and accordingly, the terminal device receives the first configuration information sent by the network device. In an optional manner, the network device is a base station, such as a gNB.

[0064] In an optional manner of the present application, the network device sends first indication information to the terminal device, and correspondingly, the terminal device receives the first indication information sent by the network device, and the first indication information is used to indicate whether the current cell supports a specific type of terminal device. In an optional manner, the first indication information is carried in a physical broadcast channel (PBCH) or a master information block (MIB) or a system information block (SIB). Here, the SIB is, for example, SIB1.

[0065] In the above solution, the specific type is, for example, the NR-light type. Further, the NR-light type can be further subdivided into multiple NR-light types, and the specific type of terminal device can refer to one or several NR-light types.

[0066] In one example, a network device sends first indication information to a terminal device, where the first indication information is used to indicate whether the current cell supports NR-light type terminal devices.

[0067] In an embodiment of the present application, the first configuration information includes multiple initial BWP configuration information, each of the multiple initial BWP configuration information is associated with a terminal type and / or terminal capability. In an optional manner, the first configuration information is carried in a second SIB. Further, optionally, the second SIB is SIB1.

[0068] It should be noted that the terminal device needs to support the bandwidth of the initial BWP of the cell to reside in the cell, otherwise the cell is considered barred. The configuration information of the initial BWP is configured in SIB1, as shown in the following Table 1:

[0069]

[0070]

[0071]

[0072]

[0073] Table 1

[0074] Table 1 above gives configuration information of an uplink initial BWP and configuration information of a downlink initial BWP. In the embodiment of the present application, in order to enable terminal devices with various terminal types and / or terminal capabilities to reside in a cell, the cell needs to configure specific initial BWP configuration information for different types of terminal types and / or terminal capabilities.

[0075] In the embodiment of the present application, multiple initial BWP configuration information is configured in the first configuration information, and each initial BWP configuration information is associated with a terminal type and / or terminal capability. The multiple initial BWP configuration information includes initial BWP configuration information associated with multiple terminal types and / or terminal capabilities respectively; wherein,

[0076] A) In an optional manner, the multiple terminal types and / or terminal capabilities are determined based on terminal types and / or terminal capabilities supported in the standard.

[0077] For example, a base station (such as a gNB) can broadcast the configuration information of the initial BWP associated with each NR-light type of terminal according to the NR-light terminal types supported in the standard.

[0078] B) In another optional manner, the multiple terminal types and / or terminal capabilities are determined based on auxiliary information provided by the core network, and the auxiliary information is used to indicate the terminal type and / or terminal capabilities of one or more terminals registered with the core network.

[0079] For example, a base station (such as gNB) broadcasts the configuration information of the initial BWP associated with each NR-light type terminal according to the auxiliary information provided by the core network. Here, during the registration process, the terminal device sends the indication information indicating the terminal type and / or terminal capability supported by itself to the AMF through a NAS message. The AMF sends the indication information (i.e., auxiliary information) received from all terminal devices to all base stations that have a logical connection with the AMF.

[0080] C) The multiple terminal types are determined based on the terminal types and / or terminal capabilities supported by the base station.

[0081] For example, a base station (such as a gNB) broadcasts the configuration information of the initial BWP associated with each NR-light type terminal according to its own capabilities (such as the terminal types and / or terminal capabilities it supports).

[0082] In the embodiment of the present application, the multiple initial BWP configuration information includes multiple uplink initial BWP configuration information and multiple downlink initial BWP configuration information. Each of the multiple uplink initial BWPs and the multiple downlink initial BWPs is associated with a terminal type and / or terminal capability.

[0083] In the embodiment of the present application, multiple uplink initial BWPs form an uplink initial BWP list, and multiple downlink initial BWPs form a downlink initial BWP list. The uplink initial BWP in the uplink initial BWP list and the downlink initial BWP in the downlink initial BWP list can be associated together in the following manner:

[0084] Method 1: Each of the multiple uplink initial BWPs and the multiple downlink initial BWPs is associated with an identification information, and different identification information is associated with different terminal types and / or terminal capabilities; wherein the uplink initial BWP and the downlink initial BWP associated with the same identification information are associated together.

[0085] Mode 2: Each of the multiple uplink initial BWPs and the multiple downlink initial BWPs has a BWP index; wherein the uplink initial BWP and the downlink initial BWP having the same BWP index are associated together.

[0086] In the above scheme, the associated uplink initial BWP and downlink initial BWP are used for uplink transmission and downlink reception, respectively. For example, in the random access process, the associated uplink initial BWP and downlink initial BWP can be used for MSG1 transmission and MSG2 reception, respectively.

[0087] The configuration information of the uplink initial BWP and the configuration information of the downlink initial BWP in the above solution are described below.

[0088] ●Uplink initial BWP configuration information

[0089] In an optional manner, the configuration information of the uplink initial BWP includes at least one of the following: the bandwidth of the uplink initial BWP, the subcarrier spacing of the uplink initial BWP, the cyclic prefix of the uplink initial BWP, the frequency information of the uplink initial BWP, RACH public configuration information, PUCCH public configuration information, and PUSCH public configuration information.

[0090] In another optional embodiment, the configuration information of the uplink initial BWP includes at least one of the following: the bandwidth of the uplink initial BWP, the subcarrier spacing of the uplink initial BWP, the cyclic prefix of the uplink initial BWP, and the frequency information of the uplink initial BWP; wherein, the configuration information of the multiple uplink initial BWPs shares at least one of the following information: RACH common configuration information, PUCCH common configuration information, and PUSCH common configuration information.

[0091] In another optional method, the configuration information of the uplink initial BWP includes at least one of the following: the bandwidth of the uplink initial BWP, and the frequency information of the uplink initial BWP; wherein, the configuration information of the multiple uplink initial BWPs shares at least one of the following information: the subcarrier spacing of the uplink initial BWP, the cyclic prefix of the uplink initial BWP, RACH common configuration information, PUCCH common configuration information, and PUSCH common configuration information.

[0092] ● Downlink initial BWP configuration information

[0093] In an optional manner, the configuration information of the downlink initial BWP includes at least one of the following: the bandwidth of the downlink initial BWP, the subcarrier spacing of the downlink initial BWP, the cyclic prefix of the downlink initial BWP, the frequency information of the downlink initial BWP, BCCH configuration information, PCCH configuration information, PDCCH public configuration information, and PDSCH public configuration information.

[0094] In another optional embodiment, the configuration information of the downlink initial BWP includes at least one of the following: the bandwidth of the downlink initial BWP, the subcarrier spacing of the downlink initial BWP, the cyclic prefix of the downlink initial BWP, the frequency information of the downlink initial BWP, BCCH configuration information, and PCCH configuration information; wherein, the configuration information of the multiple downlink initial BWPs shares at least one of the following information: PDCCH common configuration information and PDSCH common configuration information.

[0095] In another optional method, the configuration information of the downlink initial BWP includes at least one of the following: the bandwidth of the downlink initial BWP, and the frequency information of the downlink initial BWP; wherein, the configuration information of the multiple downlink initial BWPs shares at least one of the following information: the subcarrier spacing of the downlink initial BWP, the cyclic prefix of the downlink initial BWP, BCCH configuration information, PCCH configuration information, PDCCH public configuration information, and PDSCH public configuration information.

[0096] Step 202: The terminal device selects first initial BWP configuration information from the multiple initial BWP configuration information based on the first configuration information, and resides on the first initial BWP based on the first initial BWP.

[0097] In the embodiment of the present application, the terminal device may select the first initial BWP configuration information from the multiple initial BWP configuration information in the following manner:

[0098] Method I) The terminal device selects first initial BWP configuration information from the multiple initial BWP configuration information according to the first terminal type and / or first terminal capability supported by the terminal device, and the first initial BWP configuration information is associated with the first terminal type and / or first terminal capability.

[0099] Here, the terminal device may select a suitable initial BWP according to the terminal types and / or terminal capabilities supported by the terminal device and the terminal types and / or terminal capabilities associated with the configured multiple initial BWPs.

[0100] Method II) The terminal device selects the first initial BWP configuration information from the multiple initial BWP configuration information according to the first BWP index supported by the terminal device, and the first initial BWP has the first BWP index; wherein the first BWP index is associated with the first terminal type and / or the first terminal capability supported by the terminal device, and the first initial BWP configuration information is associated with the first terminal type and / or the first terminal capability.

[0101] Here, the terminal device can select a suitable initial BWP according to the BWP index supported by the terminal device and the terminal types and / or terminal capabilities associated with the configured multiple initial BWPs.

[0102] In the embodiment of the present application, after the terminal device selects the first initial BWP configuration information, it can perform at least one of the following operations:

[0103] ■Operation 1

[0104] The terminal device receives a paging PDCCH on the first initial BWP, where the paging PDCCH is used to schedule a paging message; wherein the paging PDCCH is descrambled using a P-RNTI; or, the paging PDCCH is descrambled using a dedicated RNTI.

[0105] ■Operation 2

[0106] The terminal device receives a first SI PDCCH on the first initial BWP, where the first SI PDCCH is used to schedule a first SIB; wherein the first SI PDCCH is descrambled using SI-RNTI; or, the first SI PDCCH is descrambled using a dedicated RNTI.

[0107] ■Operation 3

[0108] The terminal device initiates a random access process to the network device on the first initial BWP, wherein the first initial BWP is used by the network device to determine a first terminal type and / or a first terminal capability supported by the terminal device.

[0109] For example, after receiving SIB1, the terminal device obtains the first configuration information from SIB1 and selects a suitable initial BWP (i.e., the first initial BWP) to reside in. The terminal device receives a paging message and / or SIB and / or initiates a random access process on the first initial BWP. If the terminal device does not support the bandwidth of the selected initial BWP (i.e., the bandwidth represented by locationAndBandwidth), the terminal device considers the cell to be barred.

[0110] In the above scheme, for paging triggered by NR-light type terminal devices, AMF pushes the type information of the terminal device to the base station. The base station determines the initial BWP where the terminal device receives the paging message based on the type of the paged terminal device, and then sends the paging message on the initial BWP.

[0111] In the above scheme, when the terminal device receives the paging PDCCH of the NR-light type terminal device, it can use P-RNTI to descramble the paging PDCCH, or use the NR-light dedicated RNTI to descramble the paging PDCCH, wherein the NR-light dedicated RNTI is specified by the protocol. When the terminal device receives the SIPDCCH of the NR-light type terminal device, it can use SI-RNTI to descramble the SI PDCCH, or use the NR-light dedicated RNTI to descramble the SIPDCCH, wherein the NR-light dedicated RNTI is specified by the protocol.

[0112] In the above scheme, after the terminal device selects the initial BWP (i.e., the first initial BWP), it initiates a random access process on the first initial BWP. The network side determines whether the terminal device is an NR-light type terminal device and / or the capabilities supported by the terminal device based on the first initial BWP where the terminal device initiates the random access process.

[0113] In an optional method of the present application, the network device sends second indication information and third indication information to the terminal device, and accordingly, the terminal device receives the second indication information and third indication information sent by the network device; wherein, the second indication information is used to indicate whether the current cell allows access to a specific type of terminal device, and the third indication information is used to determine the resource configuration information of the RMSI PDCCH.

[0114] In the above scheme, the third indication information includes first index information and second index information, the first index information is used to determine the configuration information of the first CORESET, and the second index information is used to determine the configuration information of the first search space.

[0115] In the above scheme, the resource configuration information of RMSI PDCCH is used to determine the candidate time-frequency position of RMSI PDCCH. The candidate time-frequency position of RMSI PDCCH can be determined based on the configuration information of CORESET and the configuration information of search space. That is to say, "resource configuration information of RMSI PDCCH" can be understood as "resource configuration information of RMSI PDCCH and configuration information of search space".

[0116] In an embodiment of the present application, the terminal device may determine the configuration information of the first CORESET and the configuration information of the first search space in the following manner.

[0117] Method 1: If the second indication information indicates that the current cell allows access to a specific type of terminal device, then: the terminal device determines the configuration information of the first CORESET in the first table based on the first index information, and determines the configuration information of the first search space in the second table based on the second index information; wherein the first table and the second table are tables defined for the specific type of terminal device.

[0118] Method 2: If the second indication information indicates that the current cell allows access to a specific type of terminal device, then: the terminal device transforms the first index information to obtain third index information; and transforms the second index information to obtain fourth index information; the terminal device determines the configuration information of the first CORESET in the third table based on the third index information, and determines the configuration information of the first search space in the fourth table based on the fourth index information; wherein the third table and the fourth table are tables defined for common types of terminal devices.

[0119] After determining the configuration information of the first CORESET and the configuration information of the first search space in the above manner (that is, the terminal device determines the resource configuration information of the RMSI PDCCH), the terminal device receives the second SI PDCCH based on the resource configuration information of the RMSI PDCCH, and the second SI PDCCH is used to schedule the second SIB; the terminal device receives the second SIB based on the second SI PDCCH, and obtains the first configuration information from the second SIB. Further, optionally, the second SI PDCCH is descrambled using SI-RNTI; or, the second SI PDCCH is descrambled using a dedicated RNTI.

[0120] In the above solution, optionally, the second indication information and the third indication information are carried in MIB. The following Table 2 shows the content of MIB:

[0121]

[0122] Table 2

[0123] Referring to Table 2, the second indication information can be implemented through the spare bit in the MIB. If the spare bit is set to 1 (or 0), it means that the current cell allows access to NR-light type terminal devices. If the spare bit is set to 0 (or 1), it means that the current cell does not allow access to NR-light type terminal devices. The third indication information can be implemented through pdcch-ConfigSIB1 in the MIB, and pdcch-ConfigSIB1 occupies 8 bits.

[0124] For ordinary type of terminal devices, ordinary type of terminal devices (such as eMBB type of terminal devices) interpret the 8 bits corresponding to pdcch-ConfigSIB1 as follows: 4 bits of the 8 bits represent the index information of CORESET, which is used to determine the configuration information of CORESET in a table (called the third table, as shown in Table 3 below), and the other 4 bits of the 8 bits represent the index information of the search space, which is used to determine the configuration information of the search space in another table (called the fourth table).

[0125]

[0126] Table 3

[0127] It should be noted that the CORESET in the above solution can also be called "CORESET#0".

[0128] Corresponding to the above-mentioned method 1, for a terminal device of a specific type (such as NR-light type or a certain NR-light type), the interpretation of the 8 bits corresponding to pdcch-ConfigSIB1 is different from that of an ordinary terminal device. For example: if the spare bit in the MIB is set to 1 (indicating that the current cell allows access to NR-light type terminal devices), the NR-light type terminal device interprets the 8 bits corresponding to pdcch-ConfigSIB1 according to the table defined in the protocol. Specifically, 4 bits of the 8 bits represent the index information of the CORESET, which is used to determine the configuration information of the CORESET in the newly defined first table, and the other 4 bits of the 8 bits represent the index information of the search space, which is used to determine the configuration information of the search space in another newly defined second table. It should be noted that the first table is a table newly defined for an NR-light type terminal device to associate with the CORESET index information, and the second table is a table newly defined for an NR-light type terminal device to associate with the search space index information. Each index in the first table corresponds to a CORESET configuration, and each index in the second table corresponds to a search space configuration. If the spare bit in the MIB is set to 0 (indicating that the current cell does not allow access to NR-light type terminal devices), the NR-light type terminal devices do not interpret the 8 bits corresponding to pdcch-ConfigSIB1.

[0129] Corresponding to the above-mentioned method 2, for a terminal device of a specific type (such as an NR-light type or a certain NR-light type), if the spare bit in the MIB is set to 1 (indicating that the current cell allows access to NR-light type terminal devices), the NR-light type terminal device interprets the 8 bits corresponding to pdcch-ConfigSIB1 as follows: 4 bits of the 8 bits represent the index information of the CORESET, and the index information of the CORESET represented by the 4 bits can be transformed according to the offset or scaling factor defined by the standard or the predefined rules of the standard, and the configuration information of the CORESET is determined in a table (called the third table) based on the index information obtained by the transformation; the other 4 bits of the 8 bits represent the index information of the search space, and the index information of the search space represented by the 4 bits can be transformed according to the offset or scaling factor defined by the standard or the predefined rules of the standard, and the configuration information of the search space is determined in another table (called the fourth table) based on the index information obtained by the transformation. For example: if the index information represented by the 4 bits is index=a, the index used by the NR-light type terminal device is ak; further, if ak is less than 0, the index used by the NR-light type terminal device is the absolute value of ak or 0. For another example: the index information represented by 4 bits is index=a, then the index used by the NR-light type terminal device is a*k rounded up or a*k rounded down, where k is the scaling factor.

[0130] Reference Figure 3 , the CSS of the NR-light type terminal device is the most basic CSS. The terminal device obtains the second SIB (such as SIB1) on the BWP (called the lowest BWP) corresponding to the CSS, and then obtains the configuration information of the initial BWP configured for the NR-light type terminal device in SIB1. Then, the terminal device can find the initial BWP suitable for itself according to the terminal type and / or terminal capability it supports.

[0131] In the technical solution of the embodiment of the present application, the configuration information of multiple initial BWPs is defined through the second SIB, so that different types of terminal devices reside in the appropriate initial BWP, so as to achieve the purpose of expanding the cell capacity and being compatible with terminal devices of specific types (such as NR-light type). In addition, by defining the most basic CSS, the terminal device obtains the second SIB on the CSS, and obtains the configuration information of multiple initial BWPs from the second SIB, so that different types of terminal devices reside in the appropriate initial BWP, so as to achieve the purpose of expanding the cell capacity and being compatible with terminal devices of NR-light type.
