In the resource allocation method provided by the embodiment of the present disclosure, a base station sends a symbol interval parameter for two-step random access to a terminal device UE; the symbol interval parameter is used for indicating the time interval between the transmission of a physical random access channel and the transmission of a physical uplink shared channel in the two-step random access; the symbol interval parameter is selected and configured by the base station from a symbol interval parameter set, wherein the symbol interval parameter set comprises extended symbol interval parameters. Therefore, in the embodiment of the disclosure, the symbol interval parameter set includes the extended symbol interval parameter, which is a new parameter different from the original symbol interval parameter (i.e., the currently existing symbol interval parameter), so that the types of the symbol interval parameters in the symbol interval parameter set are increased, the integrity and flexibility of the base station in configuring the symbol interval parameter are improved, and the application range is expanded.

The resource configuration method, device, UE, access network device and storage medium provided in the present disclosure are described in detail below with reference to the accompanying drawings.

Fig. 1 is a flow chart of a resource allocation method provided by an embodiment of the present disclosure, which is applied to a base station, and as shown in fig. 1, the resource allocation method may include the following steps:

step 101, a symbol interval parameter for two-step random access is sent to a UE (User Equipment).

It should be noted that, the resource allocation method in the embodiment of the present disclosure may be applied to any UE. A UE may be a device that provides voice and/or data connectivity to a user. The UE may communicate with one or more core networks via a RAN (Radio Access Network ), which may be an internet of things terminal such as a sensor device, a mobile phone (or "cellular" phone) and a computer with an internet of things terminal, 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), remote Station (remote Station), access point, remote terminal (remote), access terminal (access terminal), user device (user terminal), or user agent (user agent). Alternatively, the UE may be a device of an unmanned aerial vehicle. Alternatively, the UE may be a vehicle-mounted device, for example, a laptop with a wireless communication function, or a wireless terminal externally connected to the laptop. Alternatively, the UE may be a roadside device, for example, a street lamp, a signal lamp, or other roadside devices with a wireless communication function.

And, in one embodiment of the present disclosure, the UE typically needs to access into the base station using a random access technology to establish a communication connection with the base station in order to complete subsequent interworking (e.g., call, resource request, or data transmission, etc.). The random access technology may be, for example, two-step random access, and the two-step random access technology mainly includes:

step 1, a UE sends an MsgA to a base station, and the base station receives the MsgA, where the MsgA includes a Preamble (random access Preamble) and PUSCH (Physical Uplink Shared Channel, uplink physical shared channel) resources, where the Preamble is sent on PRACH (Physical Random Access Channel ) resources;

step 2, the base station sends MsgB to the UE, and the base station receives the MsgB, wherein the MsgB comprises random access response and contention resolution information.

In the two-step random access procedure, the time interval between PRACH transmission and PUSCH transmission in MsgA is generally required to be adjusted to give the UE processing time. Wherein, the UE mainly adjusts the time interval between PRACH transmission and PUSCH transmission in MsgA based on the symbol interval parameter sent by the base station.

In one embodiment of the present disclosure, the symbol interval parameters are typically pre-configured by the base station. In one embodiment of the present disclosure, a method for configuring a symbol interval parameter by a base station may include: the base station selects a symbol interval parameter from the set of symbol interval parameters.

In one embodiment of the present disclosure, the set of symbol interval parameters may include an extended symbol interval parameter and an original symbol interval parameter. The original symbol interval parameter may include 2 and/or 4, and the extended symbol interval parameter may be any parameter different from the original symbol interval parameter (e.g., 2 and 4) if the extended symbol interval parameter is a new parameter different from the original symbol interval parameter provided in the embodiment of the present application. In one embodiment of the present disclosure, the spreading symbol interval parameter may also be greater than the original symbol interval parameter, then the spreading symbol interval parameter may be any parameter greater than 2 and 4, e.g., the spreading symbol interval parameter may comprise 6 and/or 8.

In another embodiment of the present disclosure, only the extended symbol interval parameter may be included in the symbol interval parameter set.

Thus, the symbol interval parameter selected by the base station from the symbol interval parameter set in the embodiments of the present disclosure may be an original symbol interval parameter or an extended symbol interval parameter.

In the resource allocation method provided by the embodiment of the disclosure, a base station sends a symbol interval parameter for two-step random access to a UE; the symbol interval parameter is used for indicating the time interval between PRACH transmission and PUSCH transmission in two-step random access; the symbol interval parameters are selected and configured by the base station from a set of symbol interval parameters including the extended symbol interval parameters. Therefore, in the embodiment of the disclosure, the symbol interval parameter set includes the extended symbol interval parameter, and the extended symbol interval parameter is a new parameter different from the original symbol interval parameter, so that the types of the symbol interval parameters in the symbol interval parameter set are increased, the completeness and flexibility of the base station in configuring the symbol interval parameter are improved, and the application range is expanded.

Fig. 2 is a flow chart of a resource allocation method according to another embodiment of the present disclosure, which is applied to a base station, and as shown in fig. 2, the resource allocation method may include the following steps:

step 201, selecting a symbol interval parameter for two-step random access from a symbol interval parameter set according to SCS (Sub-Carrier Space) configured by the current cell, wherein the symbol interval parameter set only comprises an extended symbol interval parameter.

In one embodiment of the present disclosure, the extended symbol interval parameter may be a new parameter different from the original symbol interval parameter, where the original symbol interval parameter is a currently existing symbol interval parameter, and may include, for example, 2 and/or 4, and then the extended symbol interval parameter may be any parameter different from 2 and 4. In another embodiment of the present disclosure, the spreading symbol interval parameter may be greater than the original symbol interval parameter, then the spreading symbol interval parameter may be any parameter greater than 2 and 4, e.g., the spreading symbol interval parameter may comprise 6 and/or 8.

And, it should be noted that, different cells may be governed by different base stations, and different base stations may support different protocols (such as 3SPPR15 protocol, 3SPPR16 protocol, or 3SPPR17 protocol, etc.), where different protocols correspond to different SCS. Thus, SCS configured by different cells will also be different. In this embodiment, the base station mainly configures the symbol interval parameters based on SCS of the current cell configuration.

In one embodiment of the present disclosure, a method for selecting a symbol interval parameter from a symbol interval parameter set according to SCS of a current cell configuration may include:

when the protocol supported by the base station governing the current cell is the R17 protocol, wherein 52.6GHz (supporting licensed/unlicensed spectrum) data of the R17 protocol introduces a higher SCS, which is 240/480/960Khz, and the extended symbol interval parameter includes 6 (i.e., the extended symbol interval parameter includes only 6, or the extended symbol interval parameter includes 6 and 8), when the SCS configured by the current cell is 240Khz or 480Khz or 960Khz, the symbol interval parameter selected from the symbol interval parameter set is a first symbol interval parameter value, and the first symbol interval parameter value may be 6.

In another embodiment of the present disclosure, a method of selecting a symbol interval parameter from a symbol interval parameter set according to SCS of a current cell configuration may include: when the protocol supported by the base station governing the current cell is the R17 protocol, wherein, when the SCS corresponding to the R17 protocol is 240/480/960Khz and the extended symbol interval parameter includes 6 and 8, when the SCS configured by the current cell is 240Khz or 480Khz, the symbol interval parameter selected from the symbol interval parameter set is a second symbol interval parameter value, and when the SCS configured by the current cell is 960Khz, the symbol interval parameter selected from the symbol interval parameter set is a third symbol interval parameter value, the third symbol interval parameter value is greater than the second symbol interval parameter value, the second symbol interval parameter value may be 6, for example, and the third symbol interval parameter value may be 8, for example.

It should also be noted that, in order to handle different types of traffic, UEs in a cell may activate different BWP (bandwidth part) in different time periods, where SCS corresponding to different BWP is also different. Based on this, in another embodiment of the present disclosure, the base station may also select a symbol interval parameter from the symbol interval parameter set based on the SCS corresponding to the BWP currently activated by the UE in the current cell.

Step 202, sending a symbol interval parameter for two-step random access to the UE.

In one embodiment of the present disclosure, after the UE receives the symbol interval parameter, two-step random access may be implemented based on the symbol interval parameter.

Fig. 3 is a flow chart of a resource allocation method according to another embodiment of the present disclosure, which is applied to a base station, and as shown in fig. 3, the resource allocation method may include the following steps:

step 301, selecting a symbol interval parameter for two-step random access from a symbol interval parameter set according to SCS configured by the current cell, wherein the symbol interval parameter set includes an extended symbol interval parameter and an original symbol interval parameter.

It should be noted that different cells may be governed by different base stations, and different base stations may support different protocols (e.g., 3SPPR15 protocol, 3SPPR16 protocol, or 3SPPR17 protocol, etc.), where different protocols correspond to different SCS. Thus, SCS configured by different cells will also be different. In this embodiment, the base station mainly configures the symbol interval parameters based on SCS of the current cell configuration.

when the protocol supported by the base station of the current cell is R17 protocol, where the SCS corresponding to the R17 protocol is 240/480/960Khz, and the spreading symbol interval parameter includes 6 (i.e., the spreading symbol interval parameter includes only 6, or the spreading symbol interval parameter includes 6 and 8), when the SCS configured by the current cell is 240Khz or 480Khz or 960Khz, the symbol interval parameter selected from the symbol interval parameter set is a first symbol interval parameter value, and the first symbol interval parameter value may be 6.

In another embodiment of the present disclosure, a method of selecting a symbol interval parameter from a symbol interval parameter set according to SCS of a current cell configuration may include: when the protocol supported by the base station governing the current cell is the R16 protocol, SCS of the corresponding FR1 in the R16 protocol is 15/30kHz, SCS of the FR2 is 60/120kHz, and the original symbol interval parameter includes 2 and 4, when the SCS of the current cell configuration is 15kHz or 30kHz, the symbol interval parameter selected from the symbol interval parameter set is a fourth symbol interval parameter value, when the SCS of the current cell configuration is 60kHz or 120kHz, the symbol interval parameter selected from the symbol interval parameter set is a fifth symbol interval parameter value, and the fifth symbol interval parameter value is greater than the fourth symbol interval parameter value, where the fifth symbol interval parameter value may be, for example, 4, and the fourth symbol interval parameter value may be, for example, 2.

It should also be noted that, in order to handle different types of traffic, UEs in a cell may activate different BWP (bandwidth part) in different time periods, where SCS corresponding to different BWP is also different. Based on this, in another embodiment of the present disclosure, the base station may also select a symbol interval parameter from the symbol interval parameter set based on the SCS corresponding to the BWP currently activated by the current cell UE.

The random access technology may be, for example, two-step random access, where the main process of the two-step random access technology includes:
