Description

[0001] This application is a divisional application, the parent application of which is: Chinese application filed on April 8, 2020, with application number 202080000689.1 and invention titled "Configuration Information Transmission Method and Apparatus, Communication Equipment and Storage Medium". Technical Field

[0002] This application relates to, but is not limited to, the field of wireless communication technology, and particularly to an information transmission method and apparatus, communication equipment and storage medium. Background Technology

[0003] Currently, the 3rd Generation Partnership Project (3GPP) is conducting research on Reduced Capability NR Devices (REDCAP) for Release (R) 17. The project aims to reduce the complexity of the UE and save costs while coexisting with R15 or R16 terminals.

[0004] However, this places high demands on the network. As the complexity of the terminal decreases, the system coverage and requirements may increase, and the utilization rate of wireless resources will decrease. In order to reduce the complexity of user equipment (UE) while minimizing the impact on the network, existing technologies need to be optimized.

[0005] From an initial bandwidth perspective, downlink and uplink are currently configured in the Remaining Minimum System Information (RMSI). For lightweight terminals, there are two scenarios: one is that the downlink and enhanced mobile broadband (eMBB) UE configurations in the RMSI are shared; the other is that the RMSI configuration is changed. If lightweight terminals and eMBB UEs share the same RMSI configuration, ensuring that both types of UEs can successfully access the network with fast access efficiency is a problem that needs further resolution.

[0037] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several UEs 11 and several base stations 12.

[0038] UE11 can be a device that provides voice and / or data connectivity to a user. UE11 can communicate with one or more core networks via a Radio Access Network (RAN). UE11 can be an IoT UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE11 can be a device in an unmanned aerial vehicle (UAV). Alternatively, UE11 can be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, UE11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0039] Base station 12 can be a network-side device in a wireless communication system. This wireless communication system can be a fourth-generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system; or it can be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, it can be a next-generation system after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0040] In this embodiment, base station 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, base station 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When base station 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DU). The central unit is equipped with a protocol stack of Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Media Access Control (MAC) layers; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of base station 12.

[0041] Base station 12 and UE11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0042] In some embodiments, UE11 can also establish E2E (End to End) connections. Examples include V2V (vehicle to vehicle), V2I (vehicle to Infrastructure), and V2P (vehicle to pedestrian) communication scenarios in vehicle-to-everything (V2X) communication.

[0043] In some embodiments, the wireless communication system described above may further include a network management device 13.

[0044] Several base stations 12 are connected to network management device 13. Network management device 13 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 13 is not limited in this embodiment.

[0045] like Figure 2 As shown, this embodiment provides an initial bandwidth configuration information transmission method, which is applied in a base station and includes:

[0046] S110: Issue configuration information for the first type of UE and the second type of UE respectively, wherein the access configuration of the first type of UE indicated by the configuration information is independent of the access configuration of the second type of UE;

[0047] The access configuration for the first type of UE is used to enable the first type of UE to access the network; the access configuration for the second type of UE is used to enable the second type of UE to access the network.

[0048] In the embodiments of this application, the first type of UE and the second type of UE are different types of terminals. Here, the first type of UE and the second type of UE may be UEs that share the same Physical Broadcast Channel (PBCH).

[0049] In some embodiments, the first type of UE may be an R17 terminal, while the second type of UE may be an R16 terminal or an R15 terminal. The first type of UE may be a Reduced Capability NR device, which can also be referred to as a Lightweight UE. The second type of UE may include an eMBB UE.

[0050] During application, the types of UEs, namely the first type and the second type, can be distinguished by the UE's identifier (ID).

[0051] The maximum bandwidth supported by the first type of UE here is less than the maximum bandwidth supported by the second type of UE.

[0052] For example, the maximum bandwidth supported by a second-class UE can be 100MHz, while the maximum bandwidth supported by a first-class UE is less than 100MHz. Furthermore, based on the maximum bandwidth supported by the first-class UE, it can be further divided into several subclasses. For example, a first subclass of the first-class UE with a maximum bandwidth of 40MHz; a second subclass of the first-class UE with a maximum bandwidth of 20MHz; and a third subclass of the first-class UE with a maximum bandwidth of 10MHz. Of course, the above subclassing is just an example; in actual implementation, the subclassing of the first-class UE is not limited to this and can be configured according to specific requirements.

[0053] Typical first-class UEs include, but are not limited to: industrial sensors, monitoring equipment, medical devices, or wearable devices.

[0054] The first and second types of UEs have independent configuration information, which controls their access to the network. The networks available for access by the first and second types of UEs include, but are not limited to, 5G, 4G, 2G, or 3G networks.

[0055] The access configurations for both Type I and Type II UEs described here are for configuring UE access to the network. (Refer to...) Figure 3 As shown, this includes, but is not limited to, any one of the following: initial access configuration, random access configuration, or paging configuration. The paging configuration may include at least: a paging configuration for sending paging messages.

[0056] Initial access configuration is used for the initial access of the UE; random access configuration is used for the random access of the UE; paging configuration is used for paging messages to UEs in idle or inactive states, triggering the UE to access the network through the paging message.

[0057] Initial access refers to the process from the terminal's first power-on, through reading system information, to initiating random access.

[0058] After initial access, the UE establishes a downlink connection with the base station and can also receive configurations sent by the base station for other random accesses of the UE (such as other random accesses including but not limited to: subsequent random accesses after the first power-on).

[0059] The random access configuration may include: the configuration of random access resources and / or the configuration of access parameters at any time. The random access parameters may indicate at least one of the following: random access type, access configuration information, including but not limited to the preamble sequence of random access, or the number of random access repetitions. Specifically, the random access configuration may include one or more of the following: two-step random access configuration (rach-ConfigCommonTwoStepRA), physical uplink shared channel configuration for random access message A (msgA-PUSH-Config), physical uplink control channel configuration for random access message B (MsgB-PUCCH-Config), modulation and coding format for random access message A (msgA-MCS), and demodulation reference signal configuration for random access message A (MsgB-DMRS-Config). Of course, this is just an example; the random access configuration may also be various parameters related to random access in rach-ConfigCommon.

[0060] Random access is an access method initiated by the UE to access the network.

[0061] Considering the difference in maximum supported bandwidth between the first type of UE and the second type of UE, independently configuring configuration information applicable to the first type of UE and the second type of UE, and controlling the access of the first type of UE and the second type of UE respectively, can make the first type of UE well compatible with the existing communication system, and make full use of the low power consumption and low complexity of the first type of UE to achieve low power communication.

[0062] If the access configurations of Type 1 and Type 2 UEs are not differentiated, in order to reduce the transmission capacity of Type 2 UEs, they might be configured to access at a larger bandwidth. If Type 1 UEs, which support lower bandwidth, share the same access configuration with Type 2 UEs, the bandwidth used in the access configuration might exceed the maximum bandwidth supported by the Type 1 UE, leading to access failures for Type 1 UEs. However, to accommodate the lower bandwidth characteristics of Type 1 UEs, Type 2 UEs might be configured to use the access configuration of Type 1 UEs. This would result in inefficient utilization of the transmission capacity of Type 2 UEs, and could even lead to low access efficiency and slow transmission rates.

[0063] In this embodiment of the application, in order to ensure the access success rate of the first type of UE, and on the other hand, in order to minimize the impact on the ability of the second type of UE to support wide bandwidth, independent access configurations are configured for the first type of UE and the second type of UE, and the access configurations of the first type of UE and the second type of UE are respectively indicated by the configuration information.

[0064] In this embodiment, the access configuration may include uplink access configuration and downlink access configuration. The uplink access configuration is used for uplink transmission during UE access; the downlink access configuration is used for downlink transmission during UE access. A typical uplink access configuration may include a random access configuration. A typical downlink access configuration may include a paging configuration. The paging configuration may at least include configuration of paging timing.

[0065] The access configuration of the first type of UE indicated by the configuration information is independent of the access configuration of the second type of UE, and includes:

[0066] The uplink access configuration of the first type of UE indicated by the configuration information is different from the uplink access configuration of the second type of UE.

[0067] and / or;

[0068] The downlink access configuration indicated by the configuration information is different from the downlink access configuration of the second type of UE.

[0069] In some embodiments, the access configuration of the first type of UE is independent of the access configuration of the second type of UE, including:

[0070] The initial access configuration of the first type of UE is different from the initial access configuration of the second type of UE.

[0071] The access configuration of the first type of UE is independent of that of the second type of UE, including: the initial access configurations of the two types of UEs are different; thus, the initial access configuration can be performed separately according to the capabilities of the first type of UE and the second type of UE during the initial access phase of the two types of UEs.

[0072] In some embodiments, the initial access configuration includes: an initial bandwidth portion (BWP) configuration; and an access configuration for the first type of UE, independent of the access configuration for the second type of UE, including:

[0073] The initial BWP configuration of the first type of UE is different from that of the second type of UE. The initial BWP configuration at this time indicates the initial BWP. For example, the initial BWP used for initial access by the first type of UE and the second type of UE are different. The center frequencies of the different initial BWPs are different. For example, the bandwidth of the initial BWP corresponding to the initial BWP configuration for the first type of UE is less than that of the initial BWP corresponding to the initial BWP configuration for the second type of UE. Here, the initial BWP of the first type of UE and the second type of UE may include: an initial uplink BWP and a downlink initial BWP. The initial uplink BWP is used for transmitting uplink information during the initial access process, and the initial downlink BWP is used for transmitting downlink information during the initial access process. The initial BWP configuration of the first type of UE is different from that of the second type of UE, including:

[0074] The initial uplink BWP configuration for Category 1 UEs differs from that for Category 2 UEs.

[0075] The initial downlink BWP configuration for Category 1 UEs differs from that for Category 2 UEs.

[0076] In some embodiments, the initial BWP configurations of the two types of UEs are the same, but the BWP access resources they use are different. Therefore, in this case, the access configuration of the first type of UE is independent of the access configuration of the second type of UE, including: the first type of UE and the second type of UE have the same initial BWP configuration, but the access resources on the same initial BWP indicated by the initial BWP configuration are different.

[0077] At this point, both Type I and Type II UEs have the same BWP configuration, meaning they use the same BWP. For example, both Type I and Type II UEs use the same initial uplink BWP 1, but they use different frequency or time resources within the initial uplink BWP 1. As another example, both Type I and Type II UEs use the same initial downlink BWP 1, but they use different frequency or time resources within the initial downlink BWP 2.

[0078] In some embodiments, the initial access configuration includes: an initial bandwidth portion (BWP) configuration; and an access configuration for the first type of UE, independent of the access configuration for the second type of UE, including:

[0079] The initial BWP configurations of the first type of UE and the second type of UE are partially the same and partially different. Specifically, for example, the uplink initial BWP configuration is the same and the downlink initial BWP configuration is different in the initial BWP configurations of the first type of UE and the second type of UE; or, the downlink initial BWP configuration is the same and the uplink initial BWP configuration is different in the initial BWP configurations of the first type of UE and the second type of UE.

[0080] For example, both Type I and Type II UEs have an initial uplink BWP of BWP0, but the initial downlink BWP of Type I UE is BWP1-1, and the initial downlink BWP of Type II UE is BWP1-2. As another example, both Type I and Type II UEs have an initial uplink BWP of BWP2, but the initial downlink BWP of Type I UE is BWP2-1, and the initial downlink BWP of Type II UE is BWP2-2.

[0081] In some embodiments, the access configuration includes: a random access configuration for random access; the random access configuration here mainly involves the resources occupied by the UE for random access, so the random access configuration is one of the aforementioned uplink access configurations.

[0082] The configuration information indicates that the access configuration of the first type of UE is independent of the access configuration of the second type of UE, including: the random access configuration of the first type of UE is different from the random access configuration of the second type of UE.

[0083] With different random access configurations, Type I UEs and Type II UEs may initiate random access on different random access resources. The random parameters used during the random access process may differ; for example, the random access preambles used may differ. Assume that Type I UEs with random access configurations correspond to random access preamble set A, and Type II UEs with random access configurations correspond to random access preamble set B. Set A includes: random access preamble 1, random access preamble 2, and random access preamble 3 to random access preamble N; while set B includes: random access preamble N+1, random access preamble N+2, and random access preamble N+3 to random access preamble N+M. N and M can both be natural numbers. Natural numbers include 0 or positive integers.

[0084] For example, the number of random access requests a UE can send in a single random access procedure varies, meaning the number of random access repetitions in a single procedure differs. To ensure the success rate of random access for Type I UEs, the random access configuration indicates that the number of random access repetitions for Type I UEs can be higher than that for Type II UEs. However, the number of random access repetitions for Type II UEs can be only 1, meaning that a single random access procedure for Type II UEs may only allow one further random access attempt. Of course, this is merely an example, and the specific limitations are not limited to this.

[0085] In some embodiments, the random access configuration includes: the configuration of random access resources.

[0086] The random access configuration includes a two-step random access process. During the two-step random access process, the terminal can complete the random access by sending random access messages (Msg)A and MsgB.

[0087] Of course, in some embodiments, the random access configuration may also include: a 4-step random access configuration, which completes the random access process through the transmission from Msg1 to Msg4.

[0088] In some embodiments, the aforementioned downlink access configuration may include at least the configuration of paging messages during the paging access process. The access configuration of the first type of UE indicated by the configuration information is independent of the access configuration of the second type of UE, including: the paging configuration of the first type of UE, which is different from the paging configuration of the second type of UE.

[0089] Therefore, the access configuration includes a paging configuration for sending paging messages. This paging configuration includes the configuration of the timing of paging message transmission. In some embodiments, the paging configuration may further include the configuration of the timing of paging message delivery and / or the configuration of the paging frame carrying the paging message. The mobility range of a first-class UE may be smaller than that of a second-class UE, or the mobility of a first-class UE may be lower than that of a second-class UE. Based on this characteristic, fewer paging opportunities can be configured for a first-class UE than for a second-class UE through independent access configuration, reducing unnecessary signaling overhead and paging resource allocation for paging messages on the base station side.

[0090] For example, the paging configuration of the first type of UE differs from that of the second type of UE, including:

[0091] The paging configuration indication of the first type of UE indicates the paging timing of the first type of UE, which is different from the paging timing of the second type of UE.

[0092] Considering the different paging frequencies and timings of Category I and Category II UEs, including at least one of the following:

[0093] The time domain resources corresponding to the paging timing of Category I UE and Category II UE are different;

[0094] The frequency domain resources corresponding to the paging timing of Category I UEs and Category II UEs are different;

[0095] The time interval between two adjacent paging events differs between Type I and Type II UEs. For example, the interval between two adjacent paging events for Type I UEs can be longer than that for Type II UEs. By increasing the time interval between paging events for Type I UEs, the frequency of paging events for Type I UEs is effectively increased, thereby further reducing the frequency with which Type I UEs enter wake-up mode to listen for paging messages, and thus further reducing the power consumption of Type I UEs. Of course, this is just an example, and the specific implementation is not limited to the example above.

[0096] In some embodiments, the delivery of access configuration information for the first type of UE and the second type of UE respectively includes:

[0097] System message block SIB1 is issued, wherein SIB1 carries configuration information of the first type of UE and the second type of UE.

[0098] SIB1 here refers to the signaling layer, and the content contained in SIB1 is carried by the physical layer's RMSI.

[0099] If both Type I and Type II UEs can share the same PBCH, then both Type I and Type II UEs will listen for the resource location information of SIB 1 on the PBCH. After listening for the resource location information of SIB 1, they will receive SIB 1 at the corresponding resource location. At this time, SIB 1 can carry the configuration information of both Type I and Type II UEs simultaneously.

[0100] Thus, after the first type of UE and the second type of UE obtain the resource location information of SIB 1 through PBCH monitoring, they can further monitor SIB 1 and thus be able to monitor their respective access configuration information.

[0101] In some embodiments, the configuration information of the first type of UE and the second type of UE indicates that the uplink access configuration used for access is different;

[0102] refer to Figure 4 As shown, SIB 1 includes: an initial uplink BWP information element (IE);

[0103] in,

[0104] The initial uplink BWP IE carrying the configuration information of the first type of UE is different from the initial uplink BWP IE carrying the configuration information of the second type of UE. This initial uplink BWP IE can be called: initialUplinkBWP IE.

[0105] In related technologies, SIB1 includes an initial uplink BWP IE. Since the access configurations of Type I UEs and Type II UEs are independent of each other, different initial uplink BWP IEs can be used to carry the access configurations of Type I UEs and Type II UEs respectively.

[0106] If the initial uplink BWP IEs corresponding to the first type of UE and the second type of UE are different, then SIB 1 will contain the access configuration information of the first type of UE and the second type of UE respectively.

[0107] In some embodiments, the configuration information of the first type of UE and the second type of UE indicates that the uplink access configuration used for access is different; the SIB 1 includes: an initial uplink BWP information element (IE);

[0108] The initial uplink BWP IE carrying the configuration information of the first type of UE and the configuration information of the second type of UE is the same, but the common configuration of the random access channel in the initial uplink BWP IE for the first type of UE and the second type of UE is different.

[0109] The access configuration of Category I UEs is independent of that of Category II UEs, but they share many configuration values. Therefore, to reduce signaling overhead in SIB 1, SIB 1 can carry only one initial uplink BWP IE. However, the random access channel common configuration contained in this initial uplink BWP differs. That is, the initial uplink BWP IE for both Category I and Category II UEs carries two random access channel common configurations: one for Category I UEs and the other for Category II UEs.

[0110] This random access channel common configuration can be abbreviated as: rach-ConfigCommon. Further, this random access channel common configuration specifically refers to:

[0111] In some embodiments, rach-ConfigCommonTwoStepRA.

[0112] In other embodiments, the initial uplink BWP IE carrying the configuration information of the first type of UE and the second type of UE is the same, but the configuration of the Physical Uplink Shared Channel Random Access Message A in the initial uplink BWP IE for the first type of UE and the second type of UE is different. This Physical Uplink Shared Channel Random Access Message A configuration can be simply referred to as: msgA-PUSH-ConfigCommon.

[0113] Using this method to carry the access configurations of independent Type 1 and Type 2 UEs can minimize the bit overhead within SIB1 and has strong compatibility with related technologies.

[0114] In some embodiments, the configuration information of the first type of UE and the second type of UE indicates that the downlink access configuration for access is different, and the SIB1 includes: an initial downlink BWP information element (IE);

[0115] in,

[0116] The initial downlink BWP IE carrying the configuration information of the first type of UE is different from the initial downlink BWP IE carrying the configuration information of the second type of UE.

[0117] This initial downlink BWP IE can also be called the initialDownlinkBWP IE.

[0118] In this embodiment, the configuration information of the first type of UE and the second type of UE is carried by different initial downlink BWP IEs in the same SIB 1. Thus, it is equivalent to separating the configuration information of the first type of UE and the second type of UE at the level of the initial downlink BWP IE.

[0119] In other embodiments, the initial downlink BWP IE carrying the configuration information of the first type of UE and the configuration information of the second type of UE is the same, and the common PDCCH configuration in the initial downlink BWP IE for the first type of UE and the second type of UE is different.

[0120] This public PDCCH configuration can also be called the pdcch-CofigCommon configuration.

[0121] In this embodiment, the configuration information of the first type of UE and the second type of UE can be carried by the same initial downlink BWP IE within the same SIB 1. Specifically, the configuration information of the first type of UE and the second type of UE is distinguished by the different common PDCCH configurations carried by the same initial downlink BWP IE within the same SIB 1. Therefore, a single initial downlink BWP IE carries common PDCCH configurations for the first type of UE and the second type of UE respectively, thus minimizing the bit overhead of SIB 1.

[0122] In some embodiments, the initial downlink BWP IE carrying the configuration information of the first type of UE and the configuration information of the second type of UE are the same, the common PDCCH configuration in the initial downlink BWP IE for the first type of UE and the second type of UE is the same, and the parameter values ​​of the downlink access configuration for the first type of UE and the second type of UE in the common PDCCH configuration are different.

[0123] In this embodiment, the configuration information of the first type of UE and the second type of UE can be carried by the same initial downlink BWP IE in the same SIB 1. Specifically, the configuration information of the first type of UE and the second type of UE is distinguished by the same initial downlink BWP IE in the same SIB 1, and the same common PDCCH configuration in the initial downlink BWP IE. However, this common PDCCH configuration contains downlink access configurations for the first type of UE and the second type of UE respectively.

[0124] For example, within this public PDCCH configuration, if the same parameter values ​​are found in the configuration information of the first type of UE and the second type of UE, they can be shared by the first type of UE and the second type of UE. However, if the parameter values ​​are different in the configuration information of the first type of UE and the second type of UE, they are recorded separately. In this way, bit overhead can be reduced as much as possible.

[0125] The different downlink access configuration parameter values ​​here can be: different paging timing configurations. For example, this paging timing configuration can also be called the firstPDCCH-MonitoringOccasionOfPO configuration.

[0126] like Figure 5 As shown in the figure, this application embodiment provides a configuration information transmission method, which is applied in a user equipment (UE) and includes:

[0127] S510: Receive configuration information sent by the base station; wherein the configuration information includes: configuration information of the first type of UE and configuration information of the second type of UE;

[0128] The access configuration of the first type of UE indicated by the configuration information is independent of the access configuration of the second type of UE;

[0129] The access configuration for the first type of UE is used to enable the first type of UE to access the network; the access configuration for the second type of UE is used to enable the second type of UE to access the network.

[0130] The UE here may be a Type I UE or a Type II UE. However, regardless of whether it is a Type I UE or a Type II UE, it will receive configuration information sent by the base station. Type I UEs and Type II UEs can extract the configuration information sent by the base station to themselves from the received configuration information according to the detection rules and their own UE type.

[0131] In some embodiments, the maximum bandwidth supported by the first type of UE is less than the maximum bandwidth supported by the second type of UE.

[0132] If the received UE is a Type 1 UE, then network access is performed according to the configuration information of the Type 1 UE;

[0133] If the received UE is a Type II UE, then network access is performed according to the configuration information of the Type II UE.

[0134] In this embodiment, the configuration information of the first type of UE and the second type of UE is configured independently. This independent configuration is reflected in the fact that the configuration information of the first type of UE and the second type of UE is at least partially different. In order to achieve the mutual independence between the configuration information of the first type of UE and the second type of UE, when the base station sends out the configuration information, it can use the same bits to indicate the same configuration value (or parameter value) in the configuration information of the first type of UE and the second type of UE, while indicating different configuration values ​​(or parameter values) separately. For example, different bits in SIB 1 can be used to indicate different configuration values ​​of the first type of UE and the second type of UE respectively.

[0135] In some embodiments, the access configuration of the first type of UE is independent of the access configuration of the second type of UE, including: the initial access configuration of the first type of UE is different from the initial access configuration of the second type of UE.

[0254] The following are several examples in conjunction with any one of the embodiments:

[0255] Example 1:

[0256] Because Redcap UE (i.e., Type 1 UE) and eMBB UE (Type 2 UE) have different terminal attributes, their communication requirements are also different. The configuration scheme introduced for LightUE type is mainly for RMSI (SIB1).

[0257] The initial access configuration is specific to Redcap UEs, resulting in an initial access configuration different from that of eMBB UEs. This initial access configuration can be indicated by configuration information. For example, the difference in configuration information between Redcap UEs and eMBB UEs can be at the initial BWP level, thus the initial BWP IE within SIB1 will be different.

[0258] In one scenario, independent configuration information is configured for the Redcap UE in the RMSI (SIB1); this configuration information indicates an access configuration applicable only to the Redcap UE, which may include the aforementioned initial access configuration, random access configuration, and / or paging configuration.

[0259] Configure a separate uplink access configuration for the Redcap UE. This means that the uplink access configuration of the Redcap UE is different from the initial uplink access configuration of the eMBB UE in SIB 1. For example, this uplink access configuration includes differences in the initial uplink access bandwidth configuration. The configuration in the separate configuration is only valid for Redcap.

[0260] In another scenario, instead of configuring a separate uplink initial access bandwidth and configuration for the Redcap UE, the IE containing the eMBB UE's configuration information is reused. However, the configuration values ​​for the Redcap UE within the corresponding IE differ from those for the eMBB UE. That is, the same IE will carry different configuration values ​​for the two types of UE configuration information.

[0261] Configure separate random access related resources for Redcap. Only specific information that requires special configuration is carried separately by SIB1. Therefore, at this time, the configuration values ​​for random access resources for the two types of UEs are carried separately in SIB1.

[0262] The base station can configure additional downlink initial access bandwidth for R15 or R16 UEs to replace the configuration in the PBCH, but this may exceed the maximum bandwidth (e.g., 20MHz) for redcap UEs. Therefore, a separate initial access bandwidth (not exceeding its maximum bandwidth) can also be configured for redcap UEs, or the configuration can remain unchanged and be determined by the UE itself. If the configured additional initial access bandwidth exceeds its bandwidth, it will not take effect for itself by default.

[0263] In the configuration of a standalone initial downlink BWP, a separate paging resource can also be configured for the UE, namely a paging resource dedicated to Redcap. This configuration can be called PCCH-Config for Redcap.

[0264] These configurations also apply where other relevant RRC signaling can reference the same IE.

[0265] Example 2:

[0266] There are two specific optimization methods for Redcap's random access configuration:

[0267] The first type:

[0268] If a Redcap UE and an R15 or R16 UE share the same initial bandwidth, a separate random access configuration can be configured for the Redcap UE. This separate random access configuration will give the Redcap UE different random access resources or random access parameters than the R15 or R16 UE.

[0269] For example, specific configuration resources include time and frequency resources for random access, and whether Redcap UE supports two-step random access configuration.

[0270] For example, specific random access time-frequency resources refer to configuring separate ROs for Redcap UEs, i.e., different PRACH resource indexes.

[0271] For example, depending on whether the network-side equipment (radio-side network elements such as base stations or access management functions such as AMF) wants the Redcap UE to support 2-step random access, the physical resources for RACH (Rapid Access Controller) can be configured for either 2-step or 4-step random access. That is, if the Redcap UE is not expected to support 2-step random access, only 4-step on-demand access resources specifically for the Redcap UE will be configured in the random access configuration. This allows control over the random access of the Redcap UE without affecting eMBB users.

[0272] In some scenarios, if the Redcap UE supports two-step random access, then a separate MSC can also be configured for the MsgB.

[0273] Using the above configuration, independently configure the access timing (Rccess) RO for the RACH-related physical resources of the new wireless NR Redcap, and whether it supports 2-step;

[0274] Furthermore, if Redcap UEs are categorized into different types, the above configuration can be further categorized. For example, two sets of configurations can be used for the required parameters, while keeping one set for the unnecessary parameters.

[0275] The second approach: If the initial access bandwidth of a separately configured Redcap is less than the maximum initial bandwidth of eMBB, then the configuration information for the first type of UE is configured separately in the initial BWP IE of SIB1.
