Referring to fig. 1, a schematic structural diagram of a wireless communication system according to an embodiment of the disclosure is shown. As shown in fig. 1, the wireless communication system is a communication system based on a cellular mobile communication technology, and may include: a number of UEs 11 and a number of access devices 12.

Wherein UE 11 may be a device that provides voice and/or data connectivity to a user. The UE 11 may communicate with one or more core networks via a radio access network (Radio Access Network, RAN), and the UE 11 may be an internet of things UE such as a sensor device, a mobile phone (or "cellular" phone) and a computer with an internet of things UE, for example, a fixed, portable, pocket, hand-held, computer-built-in or vehicle-mounted device. Such as a Station (STA), subscriber unit (subscriber unit), subscriber Station (subscriber Station), mobile Station (mobile Station), mobile Station (mobile), remote Station (remote Station), access point, remote UE (remote terminal), access UE (access terminal), user terminal, user agent (user agent), user device (user equipment), or user UE (UE). Alternatively, the UE 11 may be an unmanned aerial vehicle device. Alternatively, the UE 11 may be a vehicle-mounted device, for example, a laptop with a wireless communication function, or a wireless communication device externally connected to the laptop. Alternatively, the UE 11 may be a roadside device, for example, a street lamp, a signal lamp, or other roadside devices having a wireless communication function.

Access device 12 may be a network-side device in a wireless communication system. Wherein the wireless communication system may be a fourth generation mobile communication technology (the 4th generationmobile communication, 4G) system, also known as a long term evolution (Long Term Evolution, LTE) system; alternatively, 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 be a next generation system of the 5G system. Among them, the access network in the 5G system may be called NG-RAN (New Generation-Radio Access Network, new Generation radio access network). Or, an MTC system.

Wherein the access device 12 may be an evolved access device (eNB) employed in a 4G system. Alternatively, access device 12 may be an access device (gNB) in a 5G system that employs a centralized and distributed architecture. When the access device 12 employs a centralized and distributed architecture, it typically includes a Centralized Unit (CU) and at least two Distributed Units (DUs). A protocol stack of a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, a radio link layer control protocol (Radio Link Control, RLC) layer, and a medium access control (Media Access Control, MAC) layer is provided in the centralized unit; a Physical (PHY) layer protocol stack is provided in the distribution unit, and the specific implementation of the access device 12 is not limited by the embodiments of the present disclosure.

A wireless connection may be established between access device 12 and UE 11 over a wireless air interface. In various embodiments, the wireless air interface is a fourth generation mobile communication network technology (4G) standard-based wireless air interface; or, the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; alternatively, the wireless air interface may be a wireless air interface based on a 5G-based technology standard of a next generation mobile communication network.

The Redcap UE needs to perform early indication because of limitation of the scheduled time-frequency domain resources, that is, the type of the terminal can be identified in the random access process, so that reasonable scheduling is facilitated.

The terminal-based early identification is performed through random access channel segmentation (RACH part). The resources to be randomly accessed are divided according to the combination of characteristics (Feature combination) that need to be supported.

A part of a feature combination preamble table (featurecombination preambist) is respectively divided in a random access resource RACH-ConfigCommon used for 4-step random access (4-step RACH) and/or a random access resource RACH-ConfigCommon twosstepra used for two-step random access (2-step RACH) as a feature combination for a specific feature combination, such as a Redcap UE of 3GPP standard 17 (R17). At this time, the resources that are divided for the R17 Redcap UE to use are respectively used for the early indication of msg1 of the 4-step random access or the early indication of msgA of the two-step random access of the R17 Redcap.

In the random access procedure of the R17 Redcap UE, the early indication may be configured, and the R17 Redcap UE will preferentially use the resources indicated early.

If the network configures an early indication of msg1 or msgA for R17 Redcap, the network may determine that the UE type is R17 Redcap immediately after receiving msg1 or msgA. Thereafter, a suitable scheduling manner different from the conventional user (e.g., an emmbb UE) may be selected in the scheduling of msg2 or msgB to achieve precise scheduling.

The 3GPP standard 18 introduces enhanced reduction capability (enhance Reduced capability, eRedcap) UE, where the uplink data transmission bandwidth of eRedcap UE is limited to 5Mhz, so that the frequency domain range (nrofPRBs-PerMsgA-PO) of MsgA PUSCH configured in MsgA-PUSCH-Config in the random access resource configuration used for two-step random access may exceed the uplink support bandwidth of R18 terminal; therefore, when the eRedcap UE performs two-step random access, the msgA PUSCH cannot be successfully decoded at the base station.

Therefore, how to configure random access resources for eRedcap UE and improve the random access success rate of eRedcap UE is a problem to be solved.

As shown in fig. 2, an embodiment of the present disclosure provides an information transmission method, where the method is performed by a network side device, and includes:

Step 201: and determining resource configuration information of a first random access resource of a first type of Redcap UE, wherein the first random access resource is determined by a second type of Redcap UE based on a preset mode to be used by the second type of Redcap UE, and the data transmission bandwidth of the first type of Redcap UE is larger than or equal to that of the second type of Redcap UE.

The network-side device may include at least one of: core network equipment; access network equipment (e.g. base station)

The first type of RedCap UE may be a RedCap UE introduced by 3GPP standard 17.

In one possible implementation, the data transmission bandwidth of the first type of RedCap UEs is less than or equal to 20MHz. For example, the data transmission bandwidth of the first type of RedCap UE may be 20MHz maximum, or the like.

The second type of RedCap UE may be an eRedcap UE introduced by 3GPP standard 18.

In one possible implementation, the data transmission bandwidth of the second type of RedCap UEs is less than or equal to 5MHz. For example, the downlink data transmission bandwidth of the first two-class RedCap UE may be 20MHz, but the uplink data transmission bandwidth thereof may be 5MHz at maximum.

The first random access resource comprises at least one of: random access resources for 4-step access; random access resources for two-step access.

In one possible implementation, the first random access resource comprises a transmission resource of msgA in a two-step access.

The network side device may configure the first random access resource before the UE performs random access, and determine the resource configuration information.

Because the data transmission bandwidth of the first type of RedCap UE is smaller than 20MHz, the data transmission bandwidth of the second type of RedCap UE is covered. Therefore, the first random access resource configured for the first type of RedCap UE may be used by the second type of RedCap UE if the configured transmission bandwidth meets the requirements of the second type of RedCap UE.

In one embodiment, if the second type of Redcap UE can amplify the data receiving bandwidth to 20Mhz during the random access, the random access resource configured for the first type of Redcap UE can be used by the second type of Redcap UE during the random access.

In one possible implementation, whether the first random access resource is used by the second type of Redcap UE may include one of:

all resources of the first random access resource can be used by the second type of RedCap UE;

part of the resources in the first random access resource can be used by the second type of RedCap UE.

The predetermined manner includes, but is not limited to, one of the following: determining whether the first random access resource is used by the second type of Redcap UE through a communication protocol; and determining, by the network side device, whether the first random access resource is used by the second type Redcap UE through the indication information.

Whether the first random access resource is used by the second type Redcap UE may be predefined, or may be determined by the network side device based on the configured first random access resource.

In one possible implementation, if the first random access resource is used by the second type of Redcap UE, the network-side device may configure the first random access resource based on the first random access resource for use by the second type of Redcap UE.

For example: if the first random access resource is available for use by the second type of Redcap UE, the network device may configure the first random access resource to satisfy the bandwidth capability of the second type of Redcap UE (i.e., the data transmission bandwidth is less than or equal to 5 MHz).

If the first random access resource is not available for the second type of Redcap UE, the network device may configure the first random access resource to ignore the bandwidth capability of the second type of Redcap UE (i.e., the data transmission bandwidth is less than or equal to 5 MHz), and may only configure the first random access resource that satisfies the bandwidth capability of the first type of Redcap UE (i.e., the data transmission bandwidth is less than or equal to 5 MHz).

The second type of Redcap UE may determine whether to employ the first random access resource for random access based on a predetermined manner.

In this way, the first random access resource configured by the network side device, and the second type of RedCap UE can determine whether the second type of RedCap UE can be used in a predetermined manner. The uncertainty of using the first random access resource by the second-class Redcap UE is reduced, and the random access success rate of the second-class Redcap UE is improved.

As shown in fig. 3, an embodiment of the present disclosure provides an information transmission method, where the method is performed by a network side device, and includes:

step 301: and sending resource configuration information indicating the first random access resource.

The network side device may send the resource configuration information to the UE before the UE performs random access (including 4-step access or two-step access).

In one possible implementation, the network-side device broadcasts the resource configuration information to the UE. For example, the resource configuration information may be carried in a system message.

In one possible implementation, the resource configuration information may be carried in the MsgA-PUSCH-Config field.

Here, whether the first random access resource is used by the second type of Redcap UE may be specified by the communication protocol.

Illustratively, if the communication protocol specifies that the first random access resource is available for use by the second type of Redcap UE, the network device configures the first random access resource to satisfy the bandwidth capability of the second type of Redcap UE.

In one possible implementation, if the communication protocol specifies that the first random access resource is available for use by the second type of Redcap UE, then the second type of Redcap UE uses the first random access resource for random access, otherwise, the second type of Redcap UE does not use the first random access resource for random access.

As shown in fig. 4, an embodiment of the present disclosure provides an information transmission method, where the method is performed by a network side device, and includes:

step 401: and sending first indication information, wherein the first random access resource is used by the second-class Redcap UE to determine whether to be used by the second-class Redcap UE or not based on the first indication information.

Here, the predetermined manner may be that the base station indicates whether the first random access resource is used by the second type Redcap UE through the first indication information.

Here, the first indication information may be determined by the network side device.

In one possible implementation, the network side device may determine the first indication information based on the configured first random access resource.

For example, if the first random access resource configured by the network side device meets the bandwidth capability of the second type Redcap UE, the network side device may send the first indication information to indicate that the second type Redcap UE uses the first random access resource to perform random access. If the first random access resource configured by the network side equipment does not meet the bandwidth capability of the second type of Redcap UE, the network side equipment can send first indication information to indicate that the second type of Redcap UE does not adopt the first random access resource to carry out random access.

In one possible implementation, the network-side device may configure the first random access resource based on the first indication information.

For example, if the network side device determines that the first indication information is sent to indicate that the second type Redcap UE uses the first random access resource to perform random access, the network side device may configure the first random access resource that satisfies the bandwidth capability of the second type Redcap UE. If the network side equipment determines that the first indication information is sent to indicate that the second type of Redcap UE does not adopt the first random access resource to perform random access, the network side equipment only considers the first random access resource meeting the bandwidth capability of the first type of Redcap UE.

In one possible implementation manner, the second type of Redcap UE determines, according to the first indication information, that the network side device is configured with a first random access resource capable of being used by the second type of Redcap UE, and then the second type of Redcap UE can use the first random access resource to perform random access, otherwise, does not use the first random access resource.

In one possible implementation, the second type of Redcap UE determines that the first random access resource is not used by the second type of Redcap UE according to the first indication information, and then the second type of Redcap UE does not use the first random access resource.

In one possible implementation, the second type of Redcap UE determines, according to the first indication information, that the first random access resource is not used by the second type of Redcap UE, and the second type of Redcap UE does not use the first random access resource even if the first random access resource satisfies a bandwidth capability of the second type of Redcap UE.

In one possible implementation, the first indication information may be carried in a system message, or the first indication information may be carried in resource configuration information and sent to the UE.

In this way, the network side device can explicitly indicate whether the first random access resource is used by the second type of Redcap UE through the first indication information, and the second type of Redcap UE can determine whether the first random access resource can be adopted for random access based on at least the first indication information, so that the uncertainty of the UE in using the first random access resource is reduced, and the random access success rate of the second type of Redcap UE is improved.

The first and second sub-random access resources may be random access resources satisfying the bandwidth capability of the first type of Redcap UE. The first and second sub-random access resources may be a subset of the first random access resources.

The second sub-random access resource can be a subset of the first random access resource configured by the network side equipment for the first type of Redcap UE and used for random access; the second sub-random access resource may satisfy the bandwidth capability of the second class of Redcap UEs.

In one possible implementation, determining whether the first random access resource is for use by the second type of Redcap UE based on a predetermined manner includes one of:

a second sub random access resource in the first random access resource is indicated by the first indication information to be used by a second type of Redcap UE;

a second sub-random access resource in the first random access resource is specified by a communication protocol whether to be used by a second type of Redcap UE;

All resources in the first random access resource are indicated by the first indication information to be used by the second-class Redcap UE;

all of the first random access resources are specified by the communication protocol as to whether to be used by the second type of Redcap UE.

In one possible embodiment, if the network side device configures the second sub-random access resource and the first indication information indicates or the communication protocol specifies the second sub-random access resource for use by the second class of Redcap UEs, the second class of Redcap UEs uses the second sub-random access resource.

In one possible embodiment, if the network side device does not configure the second sub-random access resource, and the network side device does not indicate or the communication protocol does not specify the second sub-random access resource for use by the second type of Redcap UE, the second type of Redcap UE may behave according to convention (i.e., based on a predetermined manner), such as may use all of the first random access resources configured by the network side device for the first type of Redcap UE; or all resources in the first random access resources configured for the first type of Redcap UE by the network side device cannot be used.

In a possible embodiment, the network side device does not configure the second sub-random access resources of the subset, but the network side device sends an indication (such as first indication information) that the network side device can share the usage, and then the first type of users use all random access resources of RACH configured by the network side device for the second type of users according to the indication of the first indication information; or cannot use all of the random access resources for RACH configured by the network side device for the second class of users.

As shown in fig. 5, an embodiment of the present disclosure provides an information transmission method, where the method is performed by a network side device, and includes:

step 501: and sending resource configuration information indicating the second random access resource of the second type of Redcap UE.

The network side device may also configure a second random access resource for a second type of Redcap UE in addition to configuring the first random access resource for the first type of Redcap UE. The second random access resource may be a random access resource only for the Redcap UE.

The second random access resource comprises at least one of: random access resources for 4-step access; random access resources for two-step access.

In one possible implementation, the second random access resource comprises a transmission resource of msgA in a two-step access.

The resource configuration information of the second random access resource may be identified by the network side to be broadcasted to the UE. The identification information may be carried in the resource configuration information of the second random access resource, where the identification information may indicate that the second random access resource indicated by the resource configuration information is used for the second type Redcap UE.

In one possible implementation, the second type of Redcap UE may use the first random access resource (where the first indication information indicates or the communication protocol specifies that the second type of Redcap UE may be used) for random access, or may use the second random access resource for random access.

The second class of Redcap UEs may select the first random access resource or the second random access resource for random access based on the priority of the first random access resource and the priority of the second random access resource.

In one possible implementation, when the second random access resource exists, and the first indication information indicates or the communication protocol specifies that the first random access resource is available for the second type Redcap UE, the second type Redcap UE may preferentially use the second random access resource for random access because the second random access resource has a higher priority than the first random access resource.

Here, the priority of the second random access resource and the priority of the first random access resource may be specified by a communication protocol.

In one possible implementation, the priority of the second random access resource and the priority of the first random access resource may also be specified by the network side device and indicated to the UE. Alternatively, the priority of the second random access resource and the priority of the first random access resource may be agreed by the network side device and the UE.

As shown in fig. 6, an embodiment of the present disclosure provides an information transmission method, wherein the method is performed by a UE and includes:

step 601: receiving resource configuration information indicating a first random access resource of a first type of Redcap UE;

step 602: and determining whether the first random access resource is used by a second type of Redcap UE or not based on a preset mode, wherein the data transmission bandwidth of the first type of Redcap UE is larger than or equal to that of the second type of Redcap UE.

The network-side device may include at least one of: core network equipment; access network equipment (e.g., base stations).

The UEs may include a second type of Redcap UEs. The UE may also be another type of UE than the second type of RedCap UE.

The first type of RedCap UE may be a RedCap UE introduced by 3GPP standard 17.

In one possible implementation, the data transmission bandwidth of the second type of RedCap UEs is less than or equal to 5MHz. For example, the downlink data transmission bandwidth of the second type of RedCap UE may be 20MHz, but the uplink data transmission bandwidth thereof may be 5MHz at maximum.

As shown in fig. 7, an embodiment of the present disclosure provides an information transmission method, wherein the method is performed by a UE and includes:

step 901: and responding to the UE as the second-class Redcap UE, and selecting the first random access resource or the second random access resource for random access based on the priority of the second random access resource and the priority of the first random access resource.

A specific example is provided below in connection with any of the embodiments described above:

1. the network side equipment configures random access resources (namely the first random access resources) for Random Access (RACH) configured for the second type of users (namely the first type of Redcap UE and the R17 Redcap UE) or not, wherein the random access resources are usable by the specific type of terminals (namely the second type of Redcap UE and the eRedcap UE and are called as the first type of users herein);

a) As an example: the first type of UE is an eRedcap UE of R18 (different from the second type of UE, i.e., R17 redcapene);

b) As an example: the random access resources for RACH (i.e., the first random access resources described above) configured for the second class of UEs, including random access resources for 4-step random access (4-step RACH) and/or random access resources for two-step random access (2-step RACH);

2. based on 1, the communication protocol convention or the network side device configures whether the random access resource (i.e. the first random access resource) for RACH configured for the second type of user can be used by the first type of user;

a) As an example: the communication protocol specifies that if the network side equipment configures random access resource configuration for RACH configured for the second type of users, the first type of users can directly use the random access resource configured for the second type of users; (example 1 below)

b) As an example: the network side equipment configures random access resources for RACH, which can be used by the first type user to configure for the second type user; if configured, the first type of user can directly use the first type of user; if the network side equipment is not configured, the first type of user can not use the first type of user;

c) As an example: the network side equipment configures random access resources (namely the first random access resources) for RACH, which are configured for the second type of users and can not be used by the first type of users; even if a random access resource for RACH configured for the second class of users is configured, the resource (i.e., the above-mentioned first random access resource) is considered to be not selectable; (example 2 below)

As an example: the network side equipment can send an indication mark (flag) whether the first random access resource can be shared and used or not, namely, the indication is carried out by adopting a first indication message;

d) As an example: the network side equipment configures a subset of random access resources (namely the second sub random access resources) which are configured for the RACH and can be used by the first type of users;

as an embodiment, if the subset is configured, and the network side device may send a flag that can be shared, the first type of user uses the resources of the subset;

as an embodiment, if the subset is not configured, but the network does not send a flag that can be shared, the first class of users act according to a convention, for example, the network side device can be used to configure all RACH random access resources for the second class of users; or the random access resources for RACH configured for the second class of users by the network side device cannot be used.

As an embodiment, if the subset is not configured, but the network sends a flag for sharing use, the first class of users act according to a convention, for example, the network side device can be used to configure all RACH random access resources for the second class of users;

or the random access resources for RACH configured for the second class of users by the network side device cannot be used.

3. The communication protocol agrees that if the network side device configures random access resources (i.e., the second random access resources) for RACH specifically for the first class of users; the random access resource for RACH specially used for the first class user is preferentially used, otherwise, the random access resource for RACH configured for the second class user can be used according to the communication protocol convention or the mode configured by the network side equipment;

as a preferred embodiment, the network side device configures random access resources dedicated to the first type of user (example 3 below), then preferentially uses random access resources dedicated to the first type of user for RACH, otherwise if the network side device configures random access resources configured for RACH for the second type of user in a manner that can be used, then uses random access resources configured for RACH for the second type of user;

As a preferred embodiment, the network side device configures random access resources for two-step random access (2-step RACH) dedicated to the first type of user (example 3 below), then preferentially uses the random access resources for RACH dedicated to the first type of user, otherwise if the protocol agrees to use the random access resources for RACH configured by the second type of user in a manner that can be used, then uses the random access resources for RACH configured by the second type of user;

as an embodiment, the network side device configures random access resources for RACH dedicated to the first type user for two-step random access (2-step RACH) and also configures random access resources for RACH dedicated to the first type user for 4-step RACH;

as an embodiment, the network side device configures random access resources for RACH dedicated to the first class of users for two-step random access (2-step RACH), without configuring random access resources for RACH dedicated to the first class of users for 4-step random access (4-step RACH).
