Description

TECHNICAL FIELD

[0001] The invention relates, without limitation, to the field of communication technology and, in particular, to a method for transmitting information, a device for transmitting information, a communication device and a storage medium.

PREREQUISITES FOR CREATION OF THE INVENTION

[0002] Currently, the 3rd Generation Partnership Project (3GPP) is conducting design studies of NR devices with reduced capabilities (REDCAP, reduced capability) version 17 (R17) of the communication protocol. The goal of the project is to reduce the complexity and cost of user equipment (UE, user equipment) when used together with UE R15 or R16.

[0003] However, this places high demands on the network. Once terminal complexity is reduced, system coverage and system requirements can be increased so that wireless resource utilization is reduced. To reduce the impact on the network while reducing the complexity of the user equipment (UE), the prior art needs to be optimized.

[0004] From the point of view of the initial frequency band, the downlink and uplink are configured in the remaining minimum system information (RMSI, remained minimum system information). For a limited-capability UE, there may be two cases. In one case, the downlink configured in the RMSI is shared with an enhanced mobile broadband (eMBB) UE. Otherwise, the RMSI configuration is changed. If the limited-capability UE and the eMBV UE share the same RMSI configuration, then there is a problem that needs to be further solved, which is how to ensure that the two types of UEs can successfully access the network with fast access efficiency.

SUMMARY OF THE INVENTION

[0005] Embodiments of the invention provide a method for transmitting information, a device for transmitting information, a communication device, and a storage medium.

[0006] According to a first aspect of embodiments of the invention, a method for transmitting configuration information is provided. The method is applied to a base station and includes transmitting configuration information for a first type of user equipment (UE) and a second type of UE, respectively. The first access configuration of the first type UE indicated by the configuration information is independent of the second access configuration of the second type UE indicated by the configuration information. A first access configuration of a first type UE is configured to use a first type UE to access a network, and a second access configuration of a second type UE is configured to use a second type of UE to access a network.

[0007] According to a second aspect of embodiments of the invention, a method for transmitting configuration information is provided. The method is applied to a user equipment (UE) and includes receiving configuration information transmitted by a base station. The configuration information includes configuration information for a first type UE and configuration information for a second type UE. The first access configuration of the first type UE indicated by the configuration information is independent of the second access configuration of the second type UE indicated by the configuration information. A first access configuration of a first type UE is configured to use a first type UE to access a network, and a second access configuration of a second type UE is configured to use a second type of UE to access a network.

[0008] According to a third aspect of embodiments of the invention, a communication device is provided. The device contains a processor, a transceiver, memory, and executable programs that run on the processor. When the processor executes executable programs, a method for transmitting configuration information according to any technical solution of the first aspect or the second aspect of the embodiments of the invention is executed.

[0009] In the technical solution presented in the embodiments of the invention, given that the UE of the first type and the UE of the second type differ in the supported maximum frequency band, independent configurations can be adapted to the configuration information of the UE of the first type and UE of the second type to separately control access by UE of the first type and UE of the second type. The low power consumption and low complexity characteristics of the first type UE can be fully exploited to realize low power communication. Meanwhile, it is believed that the large supported bandwidth characteristic of type 2 UEs better realizes high-speed access and low-latency communication.

[00023] FIG. 1 is a diagram illustrating a wireless communication system according to an embodiment of the invention. As shown in FIG. 1, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include multiple UEs 11 and multiple base stations 12.

[00024] UE 11 may be a device that provides communications for transmitting voice and/or data to the user. UE 11 may communicate with one or more core networks via a radio access network (RAN). The UE 11 may be an IoT UE such as a touch device, a mobile phone (or cell phone), and a computer having an IoT UE, such as a desktop, portable, handheld, handheld, embedded computer, or vehicle-mounted device such as a station (STA) ), subscriber unit, subscriber station, mobile station, mobile device, remote station, access point, remote terminal, access terminal, user terminal, user agent or user equipment (UE). Alternatively, the UE 11 may also be an unmanned aerial vehicle device. Alternatively, the UE 11 may also be a vehicle-mounted device, for example, the UE 11 may be a vehicle-mounted computer with wireless communication functionality, or a wireless communication device with an external connection to a vehicle-mounted computer. Alternatively, the UE 11 may also be a roadside device, such as a wireless road light, a traffic light or other roadside device, etc.

[00025] Base station 12 may be a network device in a wireless communication system. The wireless communication system may be a 4th generation (4G) mobile communication system, also known as a long term evolution (LTE) system. The wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may also be a next generation 5G system. The access network in a 5G system can be called a new generation radio access network (NG-RAN, new generation radio access network) or a machine-type communication system (MTS, machine-type communication).

[00026] The base station 12 may be an eNB using a centralized and distributed architecture in a 4G system. Alternatively, base station 12 may be a base station (gNB) using a centralized and distributed architecture in a 5G system. When base station 12 adopts a centralized and distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DU). The CU is equipped with a protocol stack that includes a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a media access control (MAC) layer. The DU is provided with a protocol stack including a physical (PHY) layer, and the embodiment of the invention does not limit the specific implementation method of the base station 12.

[00027] A wireless connection may be established between the base station 12 and the UE 11 via a wireless air interface. In various embodiments of the invention, the wireless radio interface is a wireless radio interface based on the 4G standard. Alternatively, the wireless air interface is a wireless air interface based on the 5G standard. For example, the wireless radio interface is NR. Alternatively, the wireless radio interface may also be a wireless radio interface based on a next generation mobile communications network technology standard based on 5G.

[00028] In some embodiments, an end-to-end (E2E) connection may be established between the UE 11, such as vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-infrastructure vehicle and pedestrian (V2P, vehicle to pedestrian) and other scenarios of communication between a vehicle and all objects (V2X, vehicle to everything).

[00029] Alternatively, the wireless communication system may also include a network management device 13.

[00030] A plurality of base stations 12 are respectively connected to the network management device 13. The network management device 13 may be a core network device in a wireless communication system. For example, the network management device 13 may be a mobility management entity (MME) of an evolved packet core (EPC). Alternatively, the network management device may also be another core network device, such as a serving gateway (SGW), a public data network gateway (PGW), and a policy function block (PCRF). and charging rules function) or home subscriber server (HSS, home subscriber server). The implementation form of the network management device 13 is not limited to the embodiment of the invention.

[00031] As shown in FIG. 2, embodiments of the invention provide a method for transmitting initial band configuration information. The method is applied to a base station and includes the following.

[00032] In step S110, configuration information is transmitted respectively for the first type UE and the second type UE. The access configuration of the first type UE indicated by the configuration information is independent of the access configuration of the second type UE indicated by the configuration information.

[00033] A first type UE access configuration is configured to use a first type UE to access a network, and a second type UE access configuration is configured to use a second type UE to access a network.

[00034] The first type UE and the second type UE in the embodiment of the invention are different types of terminals. Here, the UE of the first type and the UE of the second type may be UEs sharing the same physical broadcast channel (PHB channel).

[00035] In some embodiments, the first type of UE may be a terminal R17. The second type UE may be a terminal R16 or a terminal R15. The first type of UE may be a limited capability NR device, which may be abbreviated as a Redcap UE. The second type of UE may include an eMBV UE.

[00036] When used, a UE of the first type and a UE of the second type may be distinguished by a UE ID.

[00037] Here, the maximum frequency band supported by the first type UE is less than the maximum frequency band supported by the second type UE.

[00038] For example, the maximum frequency band supported by a second type of UE may be 100 MHz, and the maximum frequency band supported by a first type of UE is less than 100 MHz. UEs of the first type can be further classified into some subclasses based on the maximum frequency band supported. For example, Type 1 UEs supporting a maximum bandwidth of 40 MHz are in the first subclass, Type 1 UEs supporting a maximum bandwidth of 20 MHz are in the second subclass, and Type 1 UEs supporting a maximum bandwidth of 10 MHz are in the third subclass. . The above classification of subclasses is merely illustrative. The first type UE subclass classification is not limited to this and can be set according to specific requirements.

[00039] A classic first type UE includes, but is not limited to, industrial sensors, control devices, medical devices, or wearable devices.

[00040] The first type UE and the second type UE have configuration information independent of each other. The configuration information is configured to control the first type UE and the second type UE to access the network. Here, the network that can be accessed by the first type UE and the second type UE includes, but is not limited to, a 5G network, a 4G network, a 2G network, or a 3G network.

[00041] Here, both the first type UE access configuration and the second type UE access configuration are used by the UE to access the network. As shown in FIG. 3, the access configuration includes, but is not limited to, any of the following: an initial access configuration, a random access configuration, or a paging configuration. The paging configuration at least includes a paging configuration for transmitting a paging message.

[00042] The initial access configuration is used by the UE for initial access. The random access configuration is used by the UE for random access. The paging configuration is configured to transmit a paging message to a UE in an idle state or an inactive state to initiate access of the UE via the paging message.

[00043] Initial access refers to the process that begins from the time the terminal is started for the first time and system information is read until random access initiation is completed.

[00044] After the initial access, the UE establishes a downlink with the base station, and the UE may receive configurations for the UE to perform other random accesses (eg, herein, other random accesses include, but are not limited to, subsequent random accesses after the first start) transmitted to the base station. station.

[00045] The random access configuration may include a random access resource configuration and/or a random access parameter configuration. The random access parameters may indicate at least one of the following: a random access mode, access configuration information including, but not limited to, a random access preamble sequence, or the number of random access repetitions. For example, the random access configuration may include one or more of a two-step random access configuration (rach-ConfigCommonTwoStepRA), a random access message A physical uplink shared channel configuration (msgA-PUSCH-Config), a random access message B physical uplink control channel configuration access (MsgB-PUCCH-Config), random access message A modulation coding scheme (msgA-MCS), and random access message B demodulation reference signal configuration (MsgB-DMRS-Config). The above items are just examples. Random access configuration can also represent various random access related settings in rach-ConfigCommon.

[00046] Random access is a network access mode that the UE actively initiates.

[00047] Considering that the first type UE and the second type UE support different maximum frequency bands, independent configurations are applied to the configuration information of the first type UE and the second type UE to separately control access of the first type UE and the second type UE. Compatibility between the first type of UE and the existing communication system can be achieved. The low power consumption and low complexity characteristics of the first type UE can be fully exploited to realize low power communication.

[00048] If the random access of the UE of the first type is not different from the random access of the UE of the second type, in order to reduce the capacity of the UE of the second type, the UEs of the second type may be configured to access a larger frequency band. In this case, if UEs of the first type supporting a small bandwidth and UEs of the second type share the same access configuration, a situation may arise where the bandwidth of the access configuration is larger than the maximum bandwidth supported by the UE of the first type, which causes UE access failure of the first type. However, if the access configuration of the second type UE is configured to match the access configuration of the first type UE in consideration of the small supported bandwidth characteristic of the first type UE, the capacity of the second type UE cannot be fully utilized, or even a situation may arise where the second type UE types have low access efficiency and low transmission speed.

[00049] In embodiments of the invention, in order to ensure the probability of successful access of a first type UE and not impact the capabilities of a second type UE supporting wide bandwidth to the maximum extent, independent access configurations are configured for the first type UE and a second type UE, and the UE access configurations of the first type and UE of the second type are respectively indicated by configuration information.

[00050] In embodiments of the invention, the access configuration may include: an uplink access configuration and a downlink access configuration. The uplink access configuration is used for uplink transmission during the UE access process. The downlink access configuration is used for downlink transmission during the UE access process. A classic uplink access configuration may include a random access configuration. A classic downlink access configuration may include a paging configuration. The paging configuration at least includes a paging event configuration.

[00051] That the access configuration of the first type UE indicated by the configuration information is independent of the access configuration of the second type UE includes that the uplink access configuration of the first type UE indicated by the configuration information is different from the uplink access configuration communications of the second type UE, and/or the downlink access configuration of the first type UE indicated by the configuration information is different from the downlink access configuration of the second type UE.

[00052] In some embodiments, the fact that the access configuration of the first type UE is independent of the access configuration of the second type UE includes that the initial access configuration of the first type UE is different from the initial access configuration of the second type UE.

[00053] That the access configuration of a first type UE is independent of the access configuration of a second type UE includes that the two types of UEs have different initial access configurations. Thus, the initial access can be configured for the two types of UEs, respectively, based on the capabilities of the first type UE and the second type UE at the initial access stage of the two UE types.

[00054] In some embodiments of the invention, the initial access configuration includes a front-end bandwidth part (BWP) configuration. That the access configuration of the first type UE is independent of the access configuration of the second type UE includes that the initial BWP configuration for the first type UE is different from the initial BWP configuration for the second type UE. In this case, the initial BWP configuration specifies the initial BWP. For example, a UE of the first type and a UE of the second type use different initial BWPs for initial access. Different starting BWPs have different center frequencies. For example, the frequency band of the initial BWP corresponding to the initial BWP configuration for a UE of the first type is smaller than the frequency band of the initial BWP corresponding to the initial BWP configuration for the second type of UE. Here, the initial BWP of both the first type UE and the second type UE may include an uplink initial BWP and a downlink initial BWP. The uplink initial BWP is used to transmit uplink information during the initial access process.

The downlink initial BWP is used to transmit downlink information during the initial access process.

[00055] That the initial BWP configuration of the first type UE is different from the initial BWP configuration of the second type UE includes that the initial uplink BWP configuration of the first type UE is different from the initial uplink BWP configuration of the second type UE; the configuration of the initial downlink BWP of the first type UE is different from the configuration of the initial downlink BWP of the second type UE.

[00056] In some embodiments of the invention, two types of UEs have the same initial BWP configuration, but use different BWP access resources. In this case, that the access configuration of the UE of the first type is independent of the access configuration of the UE of the second type includes that the UE of the first type and the UE of the second type have the same initial BWP configuration indicating different access resources in the same initial BWP.

[00057] In this case, the UE of the first type and the UE of the second type have the same BWP configuration, i.e. use the same BWP. For example, a first type UE and a second type UE use the same uplink initial BWP1, but the first type UE and a second type UE use different frequency resources or time domain resources in the uplink initial BWP1. In another example, a first type UE and a second type UE use the same downlink initial BWP2, but the first type UE and a second type UE use different frequency resources or time domain resources in the downlink initial BWP2.

[00058] In some embodiments of the invention, the initial access configuration includes a front-band part (BWP) configuration. That the access configuration of the first type UE is independent of the access configuration of the second type UE includes that the initial BWP configuration for the first type UE and the initial BWP configuration for the second type UE are partly the same and otherwise different. Specifically, the initial BWP configurations for a first type UE and a second type UE have the same uplink initial BWP configuration and different downlink initial BWP configurations, or the initial BWP configurations for a first type UE and a second type UE have the same the same configuration of the initial downlink BWP and different configurations of the initial uplink BWP.

[00059] For example, the initial uplink BWP of a first type UE and the initial uplink BWP of a second type UE are both BWP0, but the initial downlink BWP of a first type UE is BWP1-1 and the initial downlink BWP of a second type UE represents BWP1-2. As another example, the initial uplink BWP of a first type UE and the initial uplink BWP of a second type UE are both BWP2, but the initial downlink BWP of a first type UE is BWP2-1 and the initial downlink BWP of a second type UE represents BWP2-2.

[00060] In some embodiments of the invention, the initial access configuration includes a random access configuration for random access. Here, the random access configuration mainly refers to the resource occupied by the random access UE, i.e. random access configuration is one kind of uplink access configuration described above.

[00061] That the access configuration of the first type UE indicated by the configuration information is independent of the access configuration of the second type UE includes that the random access configuration of the first type UE is different from the random access configuration of the second type UE.

[00062] The random access configurations are different, then the first type UE and the second type UE can initiate random access in different random access resources. The random parameters used in the random access process may vary. For example, the random access preambles used in random access are different. Let us assume that the random access configuration specifies a random access preamble set A corresponding to a first UE type, and the random access configuration specifies a random access preamble set B corresponding to a second UE type. Set A includes random access preamble 1, random access preamble 2, random access preamble 3... and random access preamble N. Set B includes random access preamble N+1, random access preamble N+2, random access preamble N+3... and random access preamble N+M. N and M are natural numbers, including 0 or positive integers.

[00063] As another example, in different random access processes, the UE may transmit different numbers of random access requests, i.e. different random access processes involve different numbers of random access repetitions. To ensure the random access success rate of the UE of the first type, the number of random access repetitions of the UE of the first type, determined by the random access configuration, may be greater than the number of random access repetitions of the UE of the second type. The number of random access repetitions of the second type UE may be 1, i.e. the second type of UE is allowed to initiate only one random access during one random access process. The above is just an example, the specific implementation is not limited to this.

[00064] In some embodiments of the invention, the initial access configuration includes a random access resource configuration.

[00065] The random access configuration includes two-stage random access. During the two-step random access process, the terminal may transmit random access message (Msg) A and MsgB to complete the random access.

[00066] In some embodiments of the invention, the random access configuration may also include a 4-stage random access configuration. The random access process ends with the transfer of Msgl-Msg4.

[00067] In some embodiments of the invention, the above downlink access configuration may at least include a paging message configuration during the paging access process. That the access configuration of the first type UE is independent of the access configuration of the second type UE includes that the paging configuration of the first type UE is different from the paging configuration of the second type UE.

[00068] The access configuration includes a paging configuration for transmitting a paging message. The paging message configuration includes the paging message transmission event configuration. In other embodiments of the invention, the paging configuration of the paging message may also include the configuration of a paging event of issuing the paging message and/or the configuration of a paging frame carrying the paging message. The moving range of a first type UE may be less than the moving range of a second type UE, or the mobility of a first type UE is lower than the mobility of a second type UE. Based on such characteristics, independent access configurations can be used to configure fewer paging for a first type UE than for a second type UE to reduce unnecessary paging message signaling overhead and unnecessary paging resource configurations at the base station side.

[00069] For example, that the paging configuration for a first type UE is different from the paging configuration for a second type UE includes that the paging event for the paging UE of the first type, indicated by the paging configuration for the first type UE, is different from paging events for the second type UE paging.

[00070] Given that a UE of the first type and a UE of the second type may have different paging frequencies, the different paging events include at least one of the following.

[00071] The paging events of the first type UE and the second type UE correspond to different time domain resources.

[00072] The paging events of a first type UE and a second type UE correspond to different frequency domain resources.

[00073] The time interval between two adjacent paging events for a UE of the first type is different from the time interval between two adjacent paging events for a UE of the second type. For example, the time interval between two adjacent paging events for a UE of the first type may be greater than the time interval between two adjacent paging events for a UE of the second type. By increasing the time interval between two adjacent paging events for the first type UE, the frequency of paging events for the first type UE is reduced, and the frequency with which the first type UE entering the active state monitors the paging message is further reduced, so that power consumption The first type UE is further reduced. The above is just an example, and specific implementations are not limited to this.

[00074] In some embodiments of the invention, transmitting configuration information for a first type UE and a second type UE, respectively, includes transmitting a system information block SIB1. SIB1 carries configuration information for a first type UE and a second type UE respectively.

[00075] Here, SIB1 refers to the signaling level. The contents of SIB1 are carried in the remaining minimum system information (RMSI) of the physical layer.

[00076] The first type UE and the second type UE may share the same Strategic Missile Force, and the first type UE and the second type UE may listen to information about the position of the resource SIB1 in the Strategic Missile Force. After listening to the resource position information SIB1, SIB1 is received at the corresponding resource position. In this case, SIB1 may carry configuration information for both a first type UE and a second type UE.

[00077] That is, after the first type UE and the second type UE obtain resource position information of SIB1 by listening in the Strategic Missile Forces, the first type UE and the second type UE listen to SIB1 to listen to the corresponding configuration information for the access configuration.

[00078] In some embodiments of the invention, the first type UE configuration information and the second type UE configuration information indicate different uplink access configurations for access.

[00079] As shown in FIG. 4, SIB1 includes an uplink initial BWP information element (IE).

[00080] Configuration information for a first type UE and configuration information for a second type UE are carried by different IEs of the initial uplink BWP. The initial uplink BWP IE may be referred to as the initialUplinkBWP IE.

[00081] In the prior art, SIB1 includes the uplink initial BWP IE. Since the access configuration of the first type UE is independent of the access configuration of the second type UE, different IEs of the initial uplink BWP may be used to respectively carry the access configurations of the first type UE and the second type UE.

[00082] If the first type UE and the second type UE correspond to different uplink initial BWP IEs, SIB1 may include configuration information for the access configurations of the first type UE and the second type UE, respectively.

[00083] In some embodiments of the invention, the first type UE configuration information and the second type UE configuration information indicate different uplink access configurations for access. SIB1 includes the initial uplink BWP IE.

[00084] Configuration information for a first type UE and configuration information for a second type UE are carried by the same uplink initial BWP IE, and the same uplink initial BWP IE includes different general random access channel configurations for the UE of the first type and UE of the second type.

[00085] The access configuration of the first type UE is independent of the access configuration of the second type UE, but the access configuration of the first type UE has some configuration values the same as that of the second type UE access configuration. In this case, in order to reduce the signaling overhead of SIB1, SIB1 may simply carry one uplink initial BWP IE, but the uplink initial BWP IE includes various common random access channel configurations. In other words, the initial uplink BWP IE for both the first type UE and the second type UE carries two common random access channel configurations, one of which is the first type UE access configuration and the other is the second type UE access configuration.

[00086] The common random access channel configuration may be abbreviated as rach-ConfigCommon. Additionally, in some embodiments of the invention, the common random access channel configuration may be referred to as rach-ConfigCommonTwoStepRA.

[00087] In other embodiments of the invention, the initial uplink BWP IE carrying UE configuration information of the first type is the same as the initial uplink BWP IE carrying UE configuration information of the second type, and the initial uplink BWP IE includes different configurations of a physical uplink shared channel (PUSCH, physical uplink shared channel) random access message A (MsgA) for a first type UE and a second type UE. The MsgA PUSCH configuration may be called msgA-PUSCH-ConfigCommon for short.

[00088] By thus carrying independent access configurations of the first type UE and the second type UE, the bit overhead in SIB1 can be reduced to the maximum extent, and high compatibility with the prior art can be achieved.

[00089] In some embodiments of the invention, the first type UE configuration information and the second type UE configuration information indicate different downlink access configurations for access. SIB 1 includes the initial downlink BWP IE.

[00090] Configuration information for a first type UE and configuration information for a second type UE are carried by different IEs of the initial downlink BWP.

[00091] The initial downlink BWP IE may be called the initialDownlinkBWP IE.

[00092] In an embodiment of the invention, the first type UE configuration information and the second type UE configuration information are carried by different downlink initial BWP IEs in the same SIB1. That is, the first type UE configuration information and the second type UE configuration information are separated from the IE layer of the initial downlink BWP.

[00093] In some other embodiments of the invention, the first type UE configuration information and the second type UE configuration information are carried by the same downlink initial BWP IE, and the downlink initial BWP IE includes different common PDCCH configurations for the first type UE and UE of the second type.

The first type UE configuration information and the second type UE configuration information are distinguished by different common PDCCH configurations for the first type UE and the second type UE carried by the same downlink initial BWP IE in the same SIB1. The downlink initial BWP IE carries common PDCCH configurations for the first type UE and the second type UE respectively, so as to reduce the SIB1 bit overhead as much as possible.

[00096] In some embodiments of the invention, the first type UE configuration information and the second type UE configuration information are carried by the same downlink initial BWP IE, wherein the downlink initial BWP IE includes the same general PDCCH configuration for the UE of the first type and the UE of the second type, and the overall PDCCH configuration includes different parameter values for downlink access configurations for the UE of the first type and the UE of the second type.

[00098] For example, in a common PDCCH configuration, the same parameter value in the configuration information of a first type UE and a second type UE may be shared between a first type UE and a second type UE while different parameter values are respectively recorded in the configuration information UE of the first type and UE of the second type. In this way, the bit overhead can be reduced as much as possible.

For example, different bits in SIB1 are used to indicate respectively different configuration values for a first type UE and a second type UE.

[000182] The following are some examples in combination with any embodiment of the invention.

[000183] Example 1

[000184] Since the Redcap UE (ie, the first type UE) and the eMBB UE (the second type UE) have different properties, the aggregation requirements are different. The configuration solution presented for the lightweight UE is mainly for RMSI (SIB1).

[000185] A special initial access configuration is configured for the Redcap UE, which is different from the initial access configuration of the eMVB UE. The initial access configuration may be indicated by configuration information. For example, the Redcap UE configuration information and the eMBW UE configuration information may differ in the initial BWP level, such that SIB1 includes different initial BWP IEs.

[000186] In one case, separate configuration information is configured for the Redcap UE in RMSI (SIB1). The configuration information specifies the access configuration applicable only to the Redcap UE. The access configuration may include an initial access configuration, a random access configuration, and/or a paging configuration mentioned above.

[000187] The Redcap UE is configured with a separate uplink access configuration, i.e. the uplink access configuration for the Redcap UE is different from the initial uplink access configuration for the eMVB UE in SIB1. For example, an uplink access configuration includes various configurations of an initial uplink access band. A separate configuration is only effective for Redcap UEs.

[000188] In another case, the Redcap UE is not configured with a separate frequency band and uplink initial access configuration, but the IE containing the eMBV UE configuration information is multiplexed. The configuration information configuration value for the Redcap UE is different from the configuration information configuration value for the eMBB UE in the corresponding IE. In other words, the same IE may carry different configuration information configuration values for two types of UEs, respectively.

[000189] A separate resource related to random access is configured for the Redcap UE. Only information that needs to be specifically configured is transmitted to SIB1. In this case, the configuration values of the random access resources configured for the two types of UEs are respectively transferred to SIB1.

[000190] The base station may configure an additional downlink initial access frequency band for UE R15 or R16 to supersede the configuration in the Strategic Missile Forces. However, for a Redcap UE, the bandwidth may exceed the maximum bandwidth (eg, 20 MHz). Thus, the Redcap UE may be configured with a separate initial access bandwidth (not exceeding the maximum bandwidth), or the configuration is not changed but evaluated by the UE itself. When the configured additional initial access bandwidth exceeds the UE's bandwidth, the UE determines that the configuration is not applicable to it.

[000191] In a separate configuration of the initial downlink BWP, a separate paging resource may be configured for the UE, i.e. paging resource allocated to the Redcap UE. The configuration can be PCCH-Config for Redcap.

[000192] These configurations are also applicable in other RRC-related signaling using the same IE.

[000193] Example 2

[000194] Random access configuration for Redcap has been optimized. Optimization methods include the following.

[000195] First optimization method

[000196] If a Redcap UE and an R15 or R16 UE are multiplexing the same initial frequency band, a separate random access configuration may be configured for the Redcap UE. A separate random access configuration may result in a Redcap UE and an R15 or R16 UE having different random access resources or random access parameters.

[000197] For example, a particular configuration may include a time-frequency resource for random access and a configuration indicating whether the Redcap UE supports two-stage random access.

[000198] In another example, a particular random access time-frequency resource refers to a single random access event (RO) configured for a Redcap UE, i.e. to other PRACH resource indexes.

[000199] For example, a RACH resource for 2-step or 4-step random access is configured based on whether a network-side device (a wireless network element such as a base station, an access control function element, etc.) requires UE Redcap supported two-stage random access. If the network device does not require the Redcap UE to support 2-step random access, only the 4-step random access resource separately applicable to the Redcap UE is configured in the random access configuration. In this way, random access of the Redcap UE can be controlled without affecting the eMBV UE.

[000200] In some cases, if the Redcap UE supports two-stage random access, a separate MSC may be configured for MsgB.

[000201] Through the above configurations, the configuration of physical resources associated with the RACH separately for the Redcap NR UE includes: a random access (RO) event and the need to support two-step access.

[000202] Additionally, if Redcap UEs are classified into different types, the configurations described above may be supplemented with configurations for subclasses. For example, two subclasses are configured, two sets of required parameters are configured, and one set of other parameters is enabled.

[000203] Second optimization method

[000204] The separate initial access frequency band configured for the Redcap UE is less than the maximum initial access frequency band of the eMVB UE, the configuration information of the first type UE is configured separately in the initial BWP IE SIB1.

In addition, the processing component 802 may include one or more modules for providing interaction between the processing component 802 and other components.
