The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of the present invention.

These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination."

[0083] 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 1As 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 access devices 12.

[0084] UE 11 can be a device that provides voice and / or data connectivity to a user. UE 11 can communicate with one or more core networks via a Radio Access Network (RAN). UE 11 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, UE 11 can also be a device in an unmanned aerial vehicle (UAV). Alternatively, UE 11 can also 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, UE 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0085] Access device 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.

[0086] The access device 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, the access device 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access device 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access device 12.

[0087] Access device 12 and UE 11 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.

[0088] Because Redcap UEs have limited time-frequency domain resources for scheduling, they need to be indicated in advance, that is, the type of terminal can be identified during the random access process to facilitate reasonable scheduling.

[0089] Terminal-based early identification is achieved through random access channel partitioning (RACH partition). This involves dividing the random access resources according to the combination of features that need to be supported.

[0090] In the random access resources RACH-ConfigCommon used for 4-step RACH and / or RACH-ConfigCommonTwoStepRA used for 2-step RACH, a portion of the feature combination preamble list is allocated for specific feature combinations, such as for Redcap UEs in 3GPP standard 17 (R17). In this case, the resources allocated for R17 Redcap UEs are used for the early indication of msg1 in 4-step random access or the early indication of msgA in 2-step random access.

[0091] During the random access process of an R17 Redcap UE, an early indication can be configured, in which case the R17 Redcap UE will give priority to using the resources indicated in the early indication.

[0092] If the network is configured with an early indication for msg1 or msgA for R17 Redcap, the network can immediately determine that the UE type is R17 Redcap upon receiving msg1 or msgA. Subsequently, in the scheduling of msg2 or msgB, a suitable scheduling method different from that for regular users (such as eMBB UEs) can be selected to achieve precise scheduling.

[0093] 3GPP Standard 18 introduced Enhanced Reduced Capability (eRedcap) UEs. eRedcap UEs limit uplink data transmission bandwidth to 5MHz. Therefore, for two-step random access, the frequency domain range (nrofPRBs-PerMsgA-PO) of msgA PUSCH configured in the random access resource configuration MsgA-PUSCH-Config will exceed the uplink supported bandwidth of the R18 terminal. As a result, when eRedcap UEs perform two-step random access, msgA PUSCH cannot be successfully decoded at the base station.

[0094] Therefore, how to configure random access resources for eRedcap UE and improve the success rate of eRedcap UE random access is an urgent problem to be solved.

[0095] like Figure 2 As shown, this disclosure provides an information transmission method, which is executed by a network-side device and includes:

[0096] Step 201: Determine the resource configuration information of the first random access resource of the first type of Redcap UE, wherein the first random access resource is determined by the second type of Redcap UE based on a predetermined method to be available for use by the second type of Redcap UE, wherein the data transmission bandwidth of the first type of Redcap UE is greater than or equal to that of the second type of Redcap UE.

[0097] Network-side equipment may include at least one of the following: core network equipment; access network equipment (such as base stations).

[0098] The first type of RedCap UE can be the RedCap UE introduced in 3GPP standard 17.

[0099] In one possible implementation, the data transmission bandwidth of the Type I RedCap UE is less than or equal to 20MHz. For example, the data transmission bandwidth of the Type I RedCap UE can be a maximum of 20MHz.

[0100] The second type of RedCap UE can be the eRedcap UE introduced in 3GPP standard 18.

[0101] In one possible implementation, the data transmission bandwidth of a Type II RedCap UE is less than or equal to 5 MHz. For example, the downlink data transmission bandwidth of a Type I or Type II RedCap UE could be 20 MHz, but its uplink data transmission bandwidth could be a maximum of 5 MHz.

[0102] The first random access resource includes at least one of the following: random access resources for four-step access; random access resources for two-step access.

[0103] In one possible implementation, the first random access resource includes the transmission resources of msgA in the two-step access.

[0104] The network-side equipment can configure the first random access resource and determine the resource configuration information before the UE performs random access.

[0105] Since the data transmission bandwidth of Type I RedCap UEs is less than 20MHz, it covers the data transmission bandwidth of Type II RedCap UEs. Therefore, the first random access resource configured for Type I RedCap UEs can also be used by Type II RedCap UEs if the configured transmission bandwidth meets their requirements.

[0106] In one embodiment, if the data reception bandwidth of the second type Redcap UE can be amplified to 20MHz during random access, then the random access resources configured for the first type Redcap user can be used by the second type Redcap UE during random access.

[0107] In one possible implementation, whether the first random access resource is available for use by a Type 2 Redcap UE may include one of the following:

[0108] All resources in the first random access resource category are available for use by Category 2 RedCap UEs;

[0109] Some of the resources in the first random access resource can be used by the second type of RedCap UE.

[0110] The reservation method includes, but is not limited to, one of the following: determining whether the first random access resource is available for use by a Type 2 Redcap UE through a communication protocol; or determining whether the first random access resource is available for use by a Type 2 Redcap UE through indication information by a network-side device.

[0111] Whether the first random access resource is available for use by a Type 2 Redcap UE can be predefined or determined by the network-side device based on the configured first random access resource.

[0112] In one possible implementation, if the first random access resource is available for use by a Type 2 Redcap UE, then the network-side device can configure the first random access resource based on the fact that the first random access resource is available for use by a Type 2 Redcap UE.

[0113] For example, if the first random access resource can be used by a Type 2 Redcap UE, then the first random access resource configured by the network device needs to meet the bandwidth capacity of the Type 2 Redcap UE (i.e., data transmission bandwidth less than or equal to 5MHz).

[0114] If the first random access resource cannot be used by a Type 2 Redcap UE, then the network device can configure the first random access resource to ignore the bandwidth capability of the Type 2 Redcap UE (i.e., data transmission bandwidth less than or equal to 5MHz) and only configure the first random access resource that can meet the bandwidth capability of the Type 1 Redcap UE (i.e., data transmission bandwidth less than or equal to 5MHz).

[0115] Type II Redcap UEs can determine whether to use the first random access resource for random access based on a predetermined method.

[0116] In this way, the network-side equipment can determine whether the first random access resource can be used by the Type II RedCap UE through a predetermined method. This reduces the uncertainty of the Type II RedCap UE using the first random access resource and improves the success rate of random access for the Type II RedCap UE.

[0117] like Figure 3 As shown, this disclosure provides an information transmission method, which is executed by a network-side device and includes:

[0118] Step 301: Send resource configuration information indicating the first random access resource.

[0119] Network-side devices can send resource configuration information to the UE before the UE performs random access (including 4-step access or 2-step access).

[0120] In one possible implementation, the network-side device broadcasts resource configuration information to the UE. For example, the resource configuration information can be carried in a system message.

[0121] In one possible implementation, resource configuration information can be carried in the MsgA-PUSCH-Config field.

[0122] In one embodiment, the first random access resource is determined by the second type of Redcap UE based on the communication protocol to be available for use by the second type of Redcap UE.

[0123] Here, whether the first random access resource is available for use by a Type 2 Redcap UE can be specified by the communication protocol.

[0124] For example, if the communication protocol specifies that the first random access resource can be used by the second type of Redcap UE, then the first random access resource configured by the network device needs to meet the bandwidth capacity of the second type of Redcap UE.

[0125] 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.

[0126] like Figure 4 As shown, this disclosure provides an information transmission method, which is executed by a network-side device and includes:

[0127] Step 401: Send first indication information, wherein the first random access resource is determined by the second type of RedcapUE based on the first indication information as to whether it is available for use by the second type of RedcapUE.

[0128] Here, the reservation method may be that the base station indicates, through first indication information, whether the first random access resource is available for use by the second type of Redcap UE.

[0129] Here, the first indication information can be determined by the network-side device.

[0130] In one possible implementation, the network-side device can determine the first indication information based on the configured first random access resource.

[0131] For example, if the first random access resource configured by the network-side device meets the bandwidth capability of the Type II Redcap UE, the network-side device can send a first indication message to instruct the Type II Redcap UE to use the first random access resource for random access. If the first random access resource configured by the network-side device does not meet the bandwidth capability of the Type II Redcap UE, the network-side device can send a first indication message to instruct the Type II Redcap UE not to use the first random access resource for random access.

[0132] In one possible implementation, the network-side device may configure the first random access resource based on the first indication information.

[0133] For example, if the network-side device determines that sending a first indication message instructs the second type of Redcap UE to use the first random access resource for random access, then the network-side device can configure the first random access resource to meet the bandwidth capacity of the second type of Redcap UE. If the network-side device determines that sending a first indication message instructs the second type of Redcap UE not to use the first random access resource for random access, then the network-side device will only consider the first random access resource to meet the bandwidth capacity of the first type of Redcap UE.

[0134] In one possible implementation, if the second type of Redcap UE determines, based on the first indication information, that the network-side device has configured a first random access resource that can be provided to the second type of Redcap UE, then the second type of Redcap UE can use the first random access resource for random access; otherwise, it will not use the first random access resource.

[0135] In one possible implementation, if the Type II Redcap UE determines, based on the first indication information, that the first random access resource is not available for use by the Type II Redcap UE, then the Type II Redcap UE will not use the first random access resource.

[0136] In one possible implementation, the Type II Redcap UE determines, based on the first indication information, that the first random access resource is not available for use by the Type II Redcap UE, and the Type II Redcap UE does not use the first random access resource even if the first random access resource meets the bandwidth capacity of the Type II Redcap UE.

[0137] 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.

[0138] In this way, the network-side equipment can explicitly indicate whether the first random access resource is available for use by the second type of Redcap UE through the first indication information. The second type of Redcap UE can determine whether it can use the first random access resource for random access based at least on the first indication information, thereby reducing the uncertainty of the UE using the first random access resource and improving the success rate of random access for the second type of Redcap UE.

[0139] In one embodiment, the first random access resource includes: a first sub-random access resource and a second sub-random access resource, wherein the second sub-random access resource is determined by the second type of Redcap UE to be available for use by the second type of Redcap UE based on a predetermined method.

[0140] The first and second sub-random access resources can be random access resources that satisfy the bandwidth capabilities of a Type I Redcap UE. The first and second sub-random access resources can be subsets of the first random access resource.

[0141] The second sub-random access resource can be a subset of the first random access resource configured by the network-side device for random access in the Type 1 Redcap UE; the second sub-random access resource can meet the bandwidth capacity of the Type 2 Redcap UE.

[0142] In one possible implementation, determining whether the first random access resource is available for use by a Type 2 Redcap UE is based on a predetermined method, including one of the following:

[0143] The second sub-random access resource in the first random access resource is indicated by the first indication information as to whether it is available for use by a Type 2 Redcap UE;

[0144] The second sub-random access resource within the first random access resource is determined by the communication protocol as to whether it is available for use by a Type 2 Redcap UE;

[0145] All resources in the first random access resource are indicated by the first indication information as to whether they are available for use by a second type of Redcap UE;

[0146] All resources in the first random access resource are determined by the communication protocol as to whether they are available for use by the second type of Redcap UE.

[0147] In one possible embodiment, if the network-side device configures a second sub-random access resource, and the first indication information indicates or the communication protocol specifies that the second sub-random access resource is for use by a Type 2 Redcap UE, then the Type 2 Redcap UE uses the second sub-random access resource.

[0148] In one possible embodiment, if the network-side device does not configure a second sub-random access resource, and the network-side device does not indicate or the communication protocol does not specify that the second sub-random access resource is available for use by the second type of Redcap UE, then the second type of Redcap UE may behave in accordance with the agreement (i.e., based on a predetermined manner), such as using all resources in the first random access resource configured by the network-side device for the first type of Redcap UE; or not using all resources in the first random access resource configured by the network-side device for the first type of Redcap UE.

[0149] In one possible embodiment, if the network-side device does not configure the second subset of random access resources, but sends an indication that they can be shared (such as a first indication message), then the first type of user uses all the random access resources for RACH configured by the network-side device for the second type of user according to the indication of the first indication message; or cannot use all the resources in the random access resources for RACH configured by the network-side device for the second type of user.

[0150] like Figure 5 As shown, this disclosure provides an information transmission method, which is executed by a network-side device and includes:

[0151] Step 501: Send resource configuration information indicating the second random access resource for the second type of Redcap UE.

[0152] In addition to configuring the first random access resource for Type I Redcap UEs, the network-side equipment can also configure a second random access resource for Type II Redcap UEs. The second random access resource can be a random access resource used only for Redcap UEs.

[0153] The second random access resource includes at least one of the following: random access resources for four-step access; random access resources for two-step access.

[0154] In one possible implementation, the second random access resource includes the transmission resources of msgA in the two-step access.

[0155] The resource configuration information of the second random access resource can be identified by the network and broadcast to the UE. The resource configuration information of the second random access resource may carry identification information, which can indicate that the second random access resource indicated by the resource configuration information is used for a Type II Redcap UE.

[0156] In one possible implementation, the second type Redcap UE may use either the first random access resource (where the first indication information indicates or the communication protocol specifies that the second type Redcap UE may use it) or the second random access resource for random access.

[0157] In one embodiment, the priority of the second random access resource is higher than the priority of the first random access resource.

[0158] The second type of Redcap UE can select either 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.

[0159] In one possible implementation, when a 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 use by a second type of Redcap UE, the second type of 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.

[0160] In one embodiment, the priority of the second random access resource and the priority of the first random access resource are specified by the communication protocol.

[0161] Here, the priority of the second random access resource and the priority of the first random access resource can be specified by the communication protocol.

[0162] In one possible implementation, the priority of the second random access resource and the priority of the first random access resource can 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 can also be agreed upon by the network-side device and the UE.

[0163] like Figure 6 As shown, this disclosure provides an information transmission method, which is executed by a UE and includes:

[0164] Step 601: Receive resource configuration information indicating the first random access resource for the first type of Redcap UE;

[0165] Step 602: Determine whether the first random access resource is available for use by a second type of Redcap UE based on a predetermined method, wherein the data transmission bandwidth of the first type of Redcap UE is greater than or equal to that of the second type of Redcap UE.

[0166] Network-side equipment may include at least one of the following: core network equipment; access network equipment (such as base stations).

[0167] The UE can include Category 2 RedCap UEs. The UE can also be other types of UEs besides Category 2 RedCap UEs.

[0168] The first type of RedCap UE can be the RedCap UE introduced in 3GPP standard 17.

[0169] In one possible implementation, the data transmission bandwidth of the Type I RedCap UE is less than or equal to 20MHz. For example, the data transmission bandwidth of the Type I RedCap UE can be a maximum of 20MHz.

[0170] The second type of RedCap UE can be the eRedcap UE introduced in 3GPP standard 18.

[0171] In one possible implementation, the data transmission bandwidth of a Type II RedCap UE is less than or equal to 5 MHz. For example, the downlink data transmission bandwidth of a Type II RedCap UE could be 20 MHz, but its uplink data transmission bandwidth could be a maximum of 5 MHz.

[0172] The first random access resource includes at least one of the following: random access resources for four-step access; random access resources for two-step access.

[0173] In one possible implementation, the first random access resource includes the transmission resources of msgA in the two-step access.

[0174] The network-side equipment can configure the first random access resource and determine the resource configuration information before the UE performs random access.

[0175] Since the data transmission bandwidth of Type I RedCap UEs is less than 20MHz, it covers the data transmission bandwidth of Type II RedCap UEs. Therefore, the first random access resource configured for Type I RedCap UEs can also be used by Type II RedCap UEs if the configured transmission bandwidth meets their requirements.

[0176] In one embodiment, if the data reception bandwidth of the second type Redcap UE can be amplified to 20MHz during random access, then the random access resources configured for the first type Redcap user can be used by the second type Redcap UE during random access.

[0177] In one possible implementation, whether the first random access resource is available for use by a Type 2 Redcap UE may include one of the following:

[0178] All resources in the first random access resource category are available for use by Category 2 RedCap UEs;

[0179] Some of the resources in the first random access resource can be used by the second type of RedCap UE.

[0180] The reservation method includes, but is not limited to, one of the following: determining whether the first random access resource is available for use by a Type 2 Redcap UE through a communication protocol; or determining whether the first random access resource is available for use by a Type 2 Redcap UE through indication information by a network-side device.

[0181] Whether the first random access resource is available for use by a Type 2 Redcap UE can be predefined or determined by the network-side device based on the configured first random access resource.

[0182] In one possible implementation, if the first random access resource is available for use by a Type 2 Redcap UE, then the network-side device can configure the first random access resource based on the fact that the first random access resource is available for use by a Type 2 Redcap UE.

[0183] For example, if the first random access resource can be used by a Type 2 Redcap UE, then the first random access resource configured by the network device needs to meet the bandwidth capacity of the Type 2 Redcap UE (i.e., data transmission bandwidth less than or equal to 5MHz).

[0184] If the first random access resource cannot be used by a Type 2 Redcap UE, then the network device can configure the first random access resource to ignore the bandwidth capability of the Type 2 Redcap UE (i.e., data transmission bandwidth less than or equal to 5MHz) and only configure the first random access resource that can meet the bandwidth capability of the Type 1 Redcap UE (i.e., data transmission bandwidth less than or equal to 5MHz).

[0185] Type II Redcap UEs can determine whether to use the first random access resource for random access based on a predetermined method.

[0186] Network-side devices can send resource configuration information to the UE before the UE performs random access (including 4-step access or 2-step access).

[0187] In one possible implementation, the network-side device broadcasts resource configuration information to the UE. For example, the resource configuration information can be carried in a system message.

[0188] In one possible implementation, resource configuration information can be carried in the MsgA-PUSCH-Config field.

[0189] In this way, the network-side equipment can determine whether the first random access resource can be used by the Type II RedCap UE through a predetermined method. This reduces the uncertainty of the Type II RedCap UE using the first random access resource and improves the success rate of random access for the Type II RedCap UE.

[0190] In one embodiment, determining whether the first random access resource is available for use by a second type of Redcap UE based on a predetermined method includes:

[0191] The determination of whether the first random access resource is available for use by the second type of Redcap UE is based on the communication protocol.

[0192] Here, whether the first random access resource is available for use by a Type 2 Redcap UE can be specified by the communication protocol.

[0193] For example, if the communication protocol specifies that the first random access resource can be used by the second type of Redcap UE, then the first random access resource configured by the network device needs to meet the bandwidth capacity of the second type of Redcap UE.

[0194] 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.

[0195] like Figure 7 As shown, this disclosure provides an information transmission method, which is executed by a UE and includes:

[0196] Step 701: Receive the first instruction information;

[0197] Step 702: Based on the first indication information, determine whether the first random access resource is available for use by the second type of Redcap UE.

[0198] Here, the reservation method may be that the base station indicates, through first indication information, whether the first random access resource is available for use by the second type of Redcap UE.

[0199] Here, the first indication information can be determined by the network-side device.

[0200] In one possible implementation, the network-side device can determine the first indication information based on the configured first random access resource.

[0201] For example, if the first random access resource configured by the network-side device meets the bandwidth capability of the Type II Redcap UE, the network-side device can send a first indication message to instruct the Type II Redcap UE to use the first random access resource for random access. If the first random access resource configured by the network-side device does not meet the bandwidth capability of the Type II Redcap UE, the network-side device can send a first indication message to instruct the Type II Redcap UE not to use the first random access resource for random access.

[0202] In one possible implementation, the network-side device may configure the first random access resource based on the first indication information.

[0203] For example, if the network-side device determines that sending a first indication message instructs the second type of Redcap UE to use the first random access resource for random access, then the network-side device can configure the first random access resource to meet the bandwidth capacity of the second type of Redcap UE. If the network-side device determines that sending a first indication message instructs the second type of Redcap UE not to use the first random access resource for random access, then the network-side device will only consider the first random access resource to meet the bandwidth capacity of the first type of Redcap UE.

[0204] In one possible implementation, if the second type of Redcap UE determines, based on the first indication information, that the network-side device has configured a first random access resource that can be provided to the second type of Redcap UE, then the second type of Redcap UE can use the first random access resource for random access; otherwise, it will not use the first random access resource.

[0205] In one possible implementation, if the Type II Redcap UE determines, based on the first indication information, that the first random access resource is not available for use by the Type II Redcap UE, then the Type II Redcap UE will not use the first random access resource.

[0206] In one possible implementation, the Type II Redcap UE determines, based on the first indication information, that the first random access resource is not available for use by the Type II Redcap UE, and the Type II Redcap UE does not use the first random access resource even if the first random access resource meets the bandwidth capacity of the Type II Redcap UE.

[0207] 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.

[0208] In this way, the network-side equipment can explicitly indicate whether the first random access resource is available for use by the second type of Redcap UE through the first indication information. The second type of Redcap UE can determine whether it can use the first random access resource for random access based at least on the first indication information, thereby reducing the uncertainty of the UE using the first random access resource and improving the success rate of random access for the second type of Redcap UE.

[0209] In one embodiment, the first random access resource includes: a first sub-random access resource and a second sub-random access resource;

[0210] The step of determining whether the first random access resource is available for use by a second type of Redcap UE based on a predetermined method includes:

[0211] Based on the predetermined method, it is determined whether the second sub-random access resource is available for use by the second type of Redcap UE.

[0212] The first and second sub-random access resources can be random access resources that satisfy the bandwidth capabilities of a Type I Redcap UE. The first and second sub-random access resources can be subsets of the first random access resource.

[0213] The second sub-random access resource can be a subset of the first random access resource configured by the network-side device for random access in the Type 1 Redcap UE; the second sub-random access resource can meet the bandwidth capacity of the Type 2 Redcap UE.

[0214] In one possible implementation, determining whether the first random access resource is available for use by a Type 2 Redcap UE is based on a predetermined method, including one of the following:

[0215] The second sub-random access resource in the first random access resource is indicated by the first indication information as to whether it is available for use by a Type 2 Redcap UE;

[0216] The second sub-random access resource within the first random access resource is determined by the communication protocol as to whether it is available for use by a Type 2 Redcap UE;

[0217] All resources in the first random access resource are indicated by the first indication information as to whether they are available for use by a second type of Redcap UE;

[0218] All resources in the first random access resource are determined by the communication protocol as to whether they are available for use by the second type of Redcap UE.

[0219] In one possible embodiment, if the network-side device configures a second sub-random access resource, and the first indication information indicates or the communication protocol specifies that the second sub-random access resource is for use by a Type 2 Redcap UE, then the Type 2 Redcap UE uses the second sub-random access resource.

[0220] In one possible embodiment, if the network-side device does not configure a second sub-random access resource, and the network-side device does not indicate or the communication protocol does not specify that the second sub-random access resource is available for use by the second type of Redcap UE, then the second type of Redcap UE may behave in accordance with the agreement (i.e., based on a predetermined manner), such as using all resources in the first random access resource configured by the network-side device for the first type of Redcap UE; or not using all resources in the first random access resource configured by the network-side device for the first type of Redcap UE.

[0221] In one possible embodiment, if the network-side device does not configure the second subset of random access resources, but sends an indication that they can be shared (such as a first indication message), then the first type of user uses all the random access resources for RACH configured by the network-side device for the second type of user according to the indication of the first indication message; or cannot use all the resources in the random access resources for RACH configured by the network-side device for the second type of user.

[0222] like Figure 8 As shown, this disclosure provides an information transmission method, which is executed by a UE and includes:

[0223] Step 801: Receive resource configuration information for the second random access resource indicating the second type of capability reduction Redcap UE.

[0224] In addition to configuring the first random access resource for Type I Redcap UEs, the network-side equipment can also configure a second random access resource for Type II Redcap UEs. The second random access resource can be a random access resource used only for Redcap UEs.

[0225] The second random access resource includes at least one of the following: random access resources for four-step access; random access resources for two-step access.

[0226] In one possible implementation, the second random access resource includes the transmission resources of msgA in the two-step access.

[0227] The resource configuration information of the second random access resource can be identified by the network and broadcast to the UE. The resource configuration information of the second random access resource may carry identification information, which can indicate that the second random access resource indicated by the resource configuration information is used for a Type II Redcap UE.

[0228] In one possible implementation, the second type Redcap UE may use either the first random access resource (where the first indication information indicates or the communication protocol specifies that the second type Redcap UE may use it) or the second random access resource for random access.

[0229] like Figure 9 As shown, this disclosure provides an information transmission method, which is executed by a UE and includes:

[0230] Step 901: In response to the UE being a second type Redcap UE, select either 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.

[0231] In one embodiment, the priority of the second random access resource is higher than the priority of the first random access resource.

[0232] The second type of Redcap UE can select either 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.

[0233] In one possible implementation, when a 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 use by a second type of Redcap UE, the second type of 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.

[0234] In one embodiment, the priority of the second random access resource and the priority of the first random access resource are specified by the communication protocol.

[0235] Here, the priority of the second random access resource and the priority of the first random access resource can be specified by the communication protocol.

[0236] In one possible implementation, the priority of the second random access resource and the priority of the first random access resource can 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 can also be agreed upon by the network-side device and the UE.

[0237] The following provides a specific example in conjunction with any of the above embodiments:

[0238] 1. Whether the network-side equipment can configure a specific type of terminal (i.e., the second type of Redcap UE and eRedcap UE mentioned above, referred to here as the first type of user) to use the random access resources (i.e., the first random access resources mentioned above) configured for random access (RACH) for the second type of user (i.e., the first type of Redcap UE and R17 Redcap UE mentioned above);

[0239] a) As one example: the first type of UE is an R18 eRedcap UE (different from the second type of UE, i.e., R17Redcap UE);

[0240] b) As one embodiment: the random access resources configured for RACH for the second type of UE (i.e. the first random access resources mentioned above) include random access resources for 4-step RACH and / or random access resources for 2-step RACH;

[0241] 2. Based on 1, whether the communication protocol stipulates or the network-side device configures whether the first type of user can use the random access resources (i.e., the aforementioned first random access resources) configured for RACH for the second type of user;

[0242] a) As one example: the communication protocol stipulates that if the network-side device configures the random access resources for RACH for the second type of user, the first type of user can directly use the random access resources configured for the second type of user; (Example 1 below)

[0243] b) As one example: the network-side device configures the first type of user to use the random access resources for RACH configured for the second type of user; that is, if configured, the first type of user can use them directly; if the network-side device does not configure them, the first type of user cannot use them.

[0244] c) As one embodiment: the network-side device configures the first type of user to not be able to use the random access resource for RACH configured for the second type of user (i.e., the aforementioned first random access resource); then even if the random access resource for RACH configured for the second type of user is configured, it is considered that the resource (i.e., the aforementioned first random access resource) is not selectable; (Example 2 below)

[0245] As an example: the network-side device can send an indication flag indicating whether the first random access resource can be shared, that is, use the first indication message to indicate;

[0246] d) As one embodiment: The network-side device configures a subset of random access resources for RACH that can be used by the first type of user and are configured for the second type of user (i.e., the aforementioned second sub-random access resources);

[0247] As one example, if this subset is configured and the network-side device can send a flag indicating that it can be shared, then the first type of user uses the resources of this subset.

[0248] As one example, if this subset is not configured, but the network does not send a flag indicating that it can be shared, then the first type of user may, according to the agreed behavior, either use all the random access resources for RACH configured by the network-side device for the second type of user, or not use the random access resources for RACH configured by the network-side device for the second type of user.

[0249] As one example, if this subset is not configured, but the network sends a flag for shared use, then the first type of user can, according to the agreed behavior, use all the random access resources of RACH configured for the second type of user by the network-side device.

[0250] Alternatively, the random access resources for RACH configured for Type 2 users by the network-side equipment cannot be used.

[0251] 3. The communication protocol stipulates that if the network-side device is configured with random access resources for RACH specifically for Type 1 users (i.e., the aforementioned second random access resources), then the random access resources for RACH specifically for Type 1 users shall be used first. Otherwise, the random access resources for RACH configured for Type 2 users may be used according to the communication protocol or the configuration method of the network-side device.

[0252] As a preferred embodiment, if the network-side device is configured with random access resources specifically for the first type of users (Example 3 below), then the random access resources specifically for the first type of users for RACH will be used preferentially; otherwise, if the network-side device is configured to use the random access resources for RACH configured for the second type of users in a manner that can be used, then the random access resources for RACH configured for the second type of users will be used.

[0253] As a preferred embodiment, if the network-side device is configured with random access resources specifically for two-step random access (RACH) for the first type of user (Example 3 below), then the random access resources specifically for RACH for the first type of user shall be used preferentially; otherwise, if the protocol allows the use of random access resources configured for RACH for the second type of user in a manner that can be used, then the random access resources configured for RACH for the second type of user shall be used.

[0254] As one embodiment, the network-side device is configured with random access resources for RACH specifically for Type 1 users for two-step random access (2-step RACH), and also with random access resources for RACH specifically for Type 1 users for 4-step RACH;

[0255] As one embodiment, the network-side device is configured with random access resources for RACH specifically for Type 1 users for two-step random access (2-step RACH), without the need to configure random access resources for RACH specifically for Type 1 users for four-step random access (4-step RACH).

[0256] Example 1:

[0257] During the availability of the set of random access resources:

[0258] For each set of random access resources configured for the 4-step random access type and each set of random access resources configured for the 2-step access type, if a set of random access resources is configured with a Redcap indication, then the MAC should treat that set of random access resources as unavailable random access procedures that are not applicable to the RedCap indication or eRedcap indication. The corresponding standard is:

[0259] The MAC entity shall for each set of configured Random Accessresources for 4-step RA type and for each set of configured Random Accessresources for 2-step RA type:

[0260] 1>if RedCap indication is configured for a set of Random Accessresources:

[0261] 2>consider the set of Random Access resources as not available for aRandom Access procedure for which RedCap or eRedcap indication is notapplicable.

[0262] Example 2:

[0263] During the availability of the set of random access resources:

[0264] For each group of random access resources configured for the 4-step random access type and for each group of random access resources configured for the 2-step access type,

[0265] If a set of random access resources is configured with Redcap directives, and eRedcap is allowed to use that set of random access resources configured for Redcap, then the MAC should treat that set of random access resources as unavailable to random access procedures that are not applicable to Redcap directives or eRedcap directives.

[0266] Otherwise, if a set of random access resources is configured with Redcap directives but eRedcap is not allowed, then the MAC should treat that set of random access resources as unavailable random access procedures that are not applicable to Redcap directives (i.e., eRedcap is not allowed).

[0267] The corresponding standard is:

[0268] The MAC entity shall for each set of configured Random Accessresources for 4-step RA type and for each set of configured Random Accessresources for 2-step RA type:

[0269] 1>if RedCap indication is configured for a set of Random Accessresources:

[0270] 2>If eRedcap is allowed to use the set of Random Access resources configured for Redcap:

[0271] 3>consider the set of Random Access resources as not available for aRandom Access procedure for which RedCap or eRedcap indication is notapplicable.

[0272] 2>else

[0273] 3>consider the set of Random Access resources as not available for aRandom Access procedure for which RedCap indication is not applicable.

[0274] Example 3:

[0275] During the availability of the set of random access resources:

[0276] For each group of random access resources configured for the 4-step random access type and for each group of random access resources configured for the 2-step access type,

[0277] If a set of random access resources is configured with an eRedcap directive, then the MAC should treat that set of random access resources as unavailable random access procedures that are not applicable to the eRedcap directive.

[0278] If a set of random access resources is configured with a Redcap directive and allows eRedcap to use that set of random access resources configured for Redcap, and no eRedcap directive is configured for any set of random access resources (i.e., no random access resources specifically configured for eRedcap): then the MAC should treat that set of random access resources as unavailable for random access procedures that are not applicable to the Redcap directive or the eRedcap directive; otherwise, the MAC should treat that set of random access resources as unavailable for random access procedures that are not applicable to the Redcap directive.

[0279] The corresponding standard is:

[0280] The MAC entity shall for each set of configured Random Accessresources for 4-step RA type and for each set of configured Random Accessresources for 2-step RA type:

[0281] 1>if eRedCap indication is configured for a set of Random Accessresources:

[0282] 2>consider the set of Random Access resources as not available for aRandom Access procedure for which RedCap indication is not applicable.

[0283] 1>if RedCap indication is configured for a set of Random Accessresources:

[0284] 2>If eRedcap is allowed to use the set of Random Access resources configured for Redcap and if eRedCap indication is not configured for any setof Random Access resources:

[0285] 3>consider the set of Random Access resources as not available for aRandom Access procedure for which RedCap indication or eRedCap indication is not applicable.

[0286] 2>else:

[0287] 3>consider the set of Random Access resources as not available for aRandom Access procedure for which RedCap indication is not applicable.

[0288] like Figure 10 As shown, this embodiment of the disclosure provides an information transmission device 100, which, disposed in a network-side device, includes:

[0289] Processing module 110 is configured to determine a first random access resource for a first type of capability-reduced Redcap user equipment (UE); wherein the first random access resource is determined by a second type of Redcap UE based on a predetermined method to be available for use by the second type of Redcap UE, wherein the data transmission bandwidth of the first type of Redcap UE is greater than or equal to that of the second type of Redcap UE.

[0300] like Figure 11 As shown, this embodiment of the disclosure provides an information transmission device 200, which is disposed in a user equipment (UE) and includes:

[0301] Transceiver module 210 is configured to receive resource configuration information indicating the first random access resource of a Type I capability-reduced Redcap user equipment (UE);

[0302] Processing module 220 is configured to determine, based on a predetermined method, whether the first random access resource is available for use by a second type of Redcap UE, wherein the data transmission bandwidth of the first type of Redcap UE is greater than or equal to that of the second type of Redcap UE.
