Abstract

The embodiments of the application disclose an information transmission method and device, communication equipment, and a storage medium. The configuration information transmission method includes: issuing configuration information respectively for UE of the first type and UE of the second type, wherein the maximum bandwidth supported by the UE of the first type is less than the maximum bandwidthsupported by the UE of the second type. The access configuration of the UE of the first type indicated by the configuration information is independent of the access configuration of the UE of the second type; the access configuration of the UE of the first type is used for the UE of the first type to access the network; the access configuration of the UE of the second type is used for the UE of the second type to access the network.

Description

technical field

[0001] The present application relates to the technical field of wireless communication but is not limited to the technical field of wireless communication, and in particular relates to an information transmission method and device, a communication device, and a storage medium. Background technique

[0002] At present, the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) has carried out research on the light terminal (Reduced capability NR devices, REDCAP) project of the communication protocol version (Release, R) R17, and the project goal is to coexist with R15 or R16 terminals In the case of the UE, the complexity of the UE is reduced and the cost is saved.

[0003] However, this requires very high network requirements, because after the complexity of the terminal is reduced, the system coverage and system requirements may be increased, and the utilization rate of wireless resources will be reduced. , to reduce the impact on th...

Examples

example 1

[0255] Because the terminal attributes of Redcap UE (that is, the first type of UE) and eMBB UE (second type of UE) are different, the communication requirements are also different. The configuration scheme introduced for the LightUE type is mainly for RMSI (SIB1).

[0256] A unique initial access configuration is configured for the Redcap UE, so as to obtain an initial access configuration different from that of the eMBB UE, and the initial access configuration may be indicated by configuration information. For example, the difference between the configuration information of the Redcap UE and the eMBB UE may be at the initial BWP level, so the initial BWP IE in SIB1 is different.

[0257] In one case, the Redcap UE is configured with independent configuration information in the RMSI (SIB1); the configuration information indicates an access configuration that is only applicable to the Redcap UE, and the access configuration may include the aforementioned initial access configur...

example 2

[0265] To optimize the random access configuration of Redcap, there are two specific optimization methods:

[0266] The first:

[0267]If the Redcap UE reuses the same initial bandwidth as the R15 or R16 UE, an independent random access configuration can be configured for the Redcap UE. The independent random access configuration will make the Redcap UE have different random access resources or random access parameters from the R15 or R16 UE.

[0268] For example, specific configuration resources include time-frequency resources for random access, and whether the Redcap UE supports configuration of two-step follow-up access.

[0269] For another example, the specific random access time-frequency resource refers to configuring a separate RO for the Redcap UE, that is, different PRACH resource indexes.

[0270] For example, configure RACH physical resources for 2-step or 4-step random access according to whether network-side devices (such as base stations and other radio-side ...
