Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a resource allocation method, apparatus and storage medium. Background Technology

[0002] Currently, to reduce random access latency, the 3rd Generation Partnership Project (3GPP) introduced two-step random access (2-Step RACH) in Rel-16. When a terminal initiates random access, network devices differentiate between 2-step RACH and four-step random access (4-Step RACH) using different PRACH (physical random access channel) resources.

[0003] In related technologies, a reduced capability user equipment (redcap UE) has been proposed. However, the current system does not support the use of different preamble sequences in the shared RO (RACH occasion) resources for advance indication and reporting of the terminal type to the network device. This is an urgent problem to be solved. Summary of the Invention

[0046] It should be noted that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0047] The resource allocation method and apparatus provided in this disclosure will now be described in detail with reference to the accompanying drawings.

[0048] Currently, the Internet of Things (IoT) is booming, bringing numerous conveniences to people's lives and work. Among them, machine-type communication (MTC) and narrowband internet of things (NB-IoT) are typical representatives of cellular IoT technology. These technologies are now widely used in many fields such as smart cities (e.g., meter reading), smart agriculture (e.g., collecting information such as temperature and humidity), and smart transportation (e.g., shared bicycles).

[0049] For IoT applications with low data rates and high latency (e.g., meter reading, environmental monitoring), two main technologies have been proposed: MTC and NB-IoT. Currently, NB-IoT can support speeds of a few hundred kilobytes per second (kbps), while MTC can support speeds of a few megabytes per second (Mbps). However, with the continuous development of IoT applications (e.g., monitoring, smart homes, wearable devices, and industrial sensor detection), speeds of tens to hundreds of megabytes per second (Mbps) are generally required, and latency requirements are also increasing. Therefore, in communication systems, MTC and NB-IoT technologies can no longer meet the current requirements of IoT applications.

[0050] Meanwhile, MTC and NB-IoT technologies are typically deployed in basements, outdoors, and other environments where charging or battery replacement is difficult. Therefore, terminals associated with these technologies are limited by hardware, resulting in lower coverage compared to general wireless communication terminals. Furthermore, power saving is a characteristic of both MTC and NB-IoT technologies due to the application environment. Based on this situation, the requirement to design a new user equipment in 5G NR to cover these mid-range IoT devices has been proposed. In the current 3GPP (3rd Generation Partnership Project) standardization, this new terminal type is called a reduced capability (Redcap) terminal or simply NR-lite.

[0051] In the current Rel-17 discussion, it is supported to configure the same initial downlink / uplink bandwidth portion (initial DL / UL BWP) for both redcap and non-redcap terminals. Meanwhile, in order to achieve better link adaptation during random access—that is, to configure more appropriate RE (resource element) resources and MCS (modulation and coding scheme) levels for redcap terminals—PRACH resources need to be configured for redcap terminals to enable them to identify and report their terminal type early.

[0052] Based on this, embodiments of this disclosure provide a resource allocation method and apparatus to at least configure PRACH resources for redcap terminals.

[0053] Please see Figure 2 , Figure 2 This is a flowchart illustrating a resource allocation method provided in an embodiment of this disclosure.

[0054] like Figure 2 As shown, this method is executed by a network device, and the method may include, but is not limited to, the following steps:

[0055] S1: Configure indication information for the first type of terminal, wherein the indication information is used to indicate the physical random access channel (PRACH) resources shared by the first type of terminal.

[0056] The first type of terminal can be a Redcap terminal.

[0057] In this embodiment of the disclosure, the network device configures indication information for the first type of terminal, indicating the PRACH resources shared by the first type of terminal. By implementing this embodiment, the shared PRACH resources can be configured for the first type of terminal, so that the first type of terminal can use different preamble sequences in the shared RO resources to indicate in advance and report its terminal type to the network device. This enables the first type of terminal to achieve better link adaptation during random access, so as to configure more suitable resource unit (RE) resources, MCS (modulation and coding scheme) level, etc. for the first type of terminal.

[0058] It should be noted that Type 1 terminals can share the PRACH resources of Type 2 terminals. Specifically, network devices can configure RO (RACH occasion) resources only for the 4-step RACH of Type 2 terminals, or configure different RO resources for the 2-step RACH and 4-step RACH of Type 2 terminals respectively. Furthermore, Type 1 terminals may support 2-step RACH, 4-step RACH, or both. Therefore, in a current cell where both Type 1 and Type 2 terminals support 2-step RACH and 4-step RACH, the shared PRACH resources of Type 1 terminals can have multiple possibilities.

[0059] In some embodiments, when only the 4-step RACH resources of the second type of terminal are configured, the protocol stipulates, the network side configures, or determines in any other way that the random access RACH method of the first type of terminal shares the 4-step RACH resources of the second type of terminal; wherein, the random access RACH method of the first type of terminal includes at least one of the following: 4-step RACH; 2-step RACH.

[0060] It is understandable that the random access methods of the first type of terminal include 2-step RACH and 4-step RACH. The 2-step RACH and 4-step RACH of the first type of terminal can share the 4-step RACH resources of the second type of terminal when only the 4-step RACH resources of the second type of terminal are configured.

[0061] In some embodiments, the 4-step RACH of the first type of terminal, the 2-step RACH of the first type of terminal, and the 4-step RACH of the second type of terminal share the same random access opportunity (RO) resources.

[0062] It is understandable that when the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal share the 4-step RACH resources of the second type of terminal, the three can share the same RO resources.

[0063] In some embodiments, when a synchronization signal block (SSB) corresponds to multiple RO resources, a PRACH parameter (e.g., a PRACH mask) is configured for the 2-step RACH and 4-step RACH of the first type of terminal. The PRACH mask is used to determine a subset of RO resources for the 4-step RACH of the second type of terminal, and this subset of RO resources is shared between the 4-step RACH and 2-step RACH of the first type of terminal. In this disclosure, the PRACH mask is used as an example for illustration; however, those skilled in the art will understand that other PRACH parameters may also be used.

[0064] In an exemplary embodiment, when an SSB corresponds to 8 RO resources, a PRACH mask is configured for the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal. The PRACH mask is used to determine the RO subset of the 4-step RACH of the second type of terminal. For example, if there are an even number of RO resources among the 8 RO resources, then the even number of RO resources are shared with the 4-step RACH of the first type of terminal and the 2-step RACH of the first type of terminal.

[0065] In another exemplary embodiment, when an SSB corresponds to 8 RO resources, a PRACH mask is configured for the 2-step RACH and 4-step RACH of the first type of terminal. The PRACH mask is used to determine the RO subset of the 4-step RACH of the second type of terminal. For example, if there are an odd number of RO resources among the 8 RO resources, then the odd number of RO resources are shared with the 4-step RACH and 2-step RACH of the first type of terminal.

[0066] In some embodiments, when one SSB corresponds to multiple RO resources, a first PRACH mask and a second PRACH mask are configured for the 2-step RACH and 4-step RACH of the first type of terminal, respectively; the first PRACH mask is used to determine a first subset of the RO resources of the 4-step RACH of the second type of terminal and share the first subset with the 4-step RACH of the first type of terminal; the second PRACH mask is used to determine a second subset of the RO resources of the 4-step RACH of the second type of terminal and share the second subset with the 2-step RACH of the first type of terminal.

[0067] In an exemplary embodiment, when an SSB corresponds to 8 RO resources, a first PRACH parameter (e.g., a first PRACH mask) and a second PRACH parameter (e.g., a second PRACH mask) are configured for the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal, respectively. The first PRACH mask is used to determine a first subset of the 8 RO resources of the 4-step RACH of the second type of terminal, for example, an odd number of RO resources, and shares the first subset (odd number of RO resources) with the 4-step RACH of the first type of terminal. The second PRACH mask is used to determine a second subset of the RO resources of the 4-step RACH of the second type of terminal, for example, an even number of RO resources, and shares the second subset (even number of RO resources) with the 2-step RACH of the first type of terminal.

[0068] In another exemplary embodiment, when an SSB corresponds to 8 RO resources, a first PRACH mask and a second PRACH mask are configured for the 2-step RACH and 4-step RACH of the first type of terminal, respectively. The first PRACH mask is used to determine a first subset of the 8 RO resources of the 4-step RACH of the second type of terminal, for example, an even number of RO resources, and shares the first subset (even number of RO resources) with the 4-step RACH of the first type of terminal. The second PRACH mask is used to determine a second subset of the RO resources of the 4-step RACH of the second type of terminal, for example, an odd number of RO resources, and shares the second subset (odd number of RO resources) with the 2-step RACH of the first type of terminal.

[0069] In some embodiments, when one SSB corresponds to multiple RO resources, a third PRACH mask and a fourth PRACH mask are configured for the 2-step RACH and 4-step RACH of the first type of terminal, respectively; the first PRACH mask is used to determine a third subset of the RO resources of the 4-step RACH of the second type of terminal and share the third subset with the 4-step RACH of the first type of terminal; the second PRACH mask is used to determine a fourth subset of the RO resources of the 4-step RACH of the first type of terminal and share the fourth subset with the 2-step RACH of the first type of terminal.

[0070] In an exemplary embodiment, when one SSB corresponds to 8 RO resources, a third PRACH mask and a fourth PRACH mask are configured for the 2-step RACH and 4-step RACH of the first type of terminal, respectively. The first PRACH mask is used to determine a third subset of the RO resources of the 4-step RACH of the second type of terminal, such as an even number of RO resources, and shares the third subset (the even number of RO resources) with the 4-step RACH of the first type of terminal. The second PRACH mask is used to determine a fourth subset of the RO resources of the 4-step RACH of the first type of terminal, such as the first RO resource among the even number of RO resources, and shares the fourth subset (the first RO resource among the even number of RO resources) with the 2-step RACH of the first type of terminal.

[0071] In some embodiments, when an SSB corresponds to multiple RO resources, if a PRACH mask is configured for the 4-step RACH of the first type of terminal but not for the 2-step RACH of the first type of terminal, the 2-step RACH of the first type of terminal uses the same RO resources as the 4-step RACH of the first type of terminal or uses all the same RO resources as the 4-step RACH of the second type of terminal.

[0072] In an exemplary embodiment, when an SSB corresponds to 8 RO resources, when a PRACH mask is configured for the 4-step RACH of a first type of terminal, and this PRACH mask is used, for example, to determine that the 4-step RACH of the first type of terminal shares an even number of RO resources, but no PRACH mask is configured for the 2-step RACH of the first type of terminal, the 2-step RACH of the first type of terminal uses the same RO resources as the 4-step RACH of the first type of terminal, for example, an even number of RO resources; or uses the same RO resources as the 4-step RACH of the second type of terminal.

[0073] When an SSB corresponds to multiple RO resources, if a PRACH mask is configured for the 2-step RACH of a Type 1 terminal but not for the 4-step RACH of the Type 1 terminal, the 4-step RACH of the Type 1 terminal uses the same RO resource as the 2-step RACH of the Type 1 terminal; or, it uses the same RO resource as the 4-step RACH of the Type 2 terminal; or, configuring a PRACH mask for the 2-step RACH of the Type 1 terminal is not supported, but a PRACH mask is not configured for the 4-step RACH of the Type 1 terminal.

[0074] In some embodiments, when configuring 2-step RACH resources for the second type of terminal and 4-step RACH resources for the second type of terminal, the indication information is used to indicate that the network device instructs the first type of terminal to share at least a portion of the RACH resources of the second type of terminal via first signaling.

[0075] In this embodiment of the disclosure, the first signaling may be RMSI (remaining minimum system information), RRC (radio resource control), DCI (downlink control information), MAC CE (media access control element), OSI (other system information), etc.

[0076] Specifically, when configuring 2-step RACH resources for the second type of terminal and 4-step RACH resources for the second type of terminal, the network device instructs the first type of terminal to share the 2-step RACH resources of the second type of terminal via a first signaling instruction, or the network device instructs the first type of terminal to share the 4-step RACH resources of the second type of terminal via a first signaling instruction, or the network device instructs the first type of terminal to share the 2-step RACH resources of the second type of terminal and the 4-step RACH resources of the second type of terminal via a first signaling instruction.

[0077] In some embodiments, the network device instructs a first type of terminal to share at least a portion of the PRACH resources of a second type of terminal via a first signaling, including: configuring the same first indication parameter for the 2-step RACH and the 4-step RACH of the first type of terminal; or, configuring an independent second indication parameter for the 2-step RACH and the 4-step RACH of the first type of terminal respectively.

[0078] Specifically, the same first indication parameter is configured for the 2-step RACH and the 4-step RACH of the first type of terminal, for example, a 1-bit indication parameter or a 2-bit indication parameter; or, an independent second indication parameter is configured for the 2-step RACH and the 4-step RACH of the first type of terminal, for example, a 1-bit indication parameter or a 2-bit indication parameter is configured for each.

[0079] In some embodiments, the first indication parameter or the second indication parameter is used to indicate that the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal share only one of the RO resources of the 2-step RACH of the second type of terminal and the RO resources of the 4-step RACH of the second type of terminal; or, the first indication parameter or the second indication parameter is used to indicate that the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal share at least one of the RO resources of the 2-step RACH of the second type of terminal and the RO resources of the 4-step RACH of the second type of terminal.

[0080] In an exemplary embodiment, the same first indication parameter is configured for the 2-step RACH and the 4-step RACH of the first type of terminal. For example, in the case of a 1-bit indication parameter, if the 1-bit indication parameter is "0", it indicates that the 2-step RACH and the 4-step RACH of the first type of terminal share only the RO resources of the 2-step RACH of the second type of terminal; if the 1-bit indication parameter is "1", it indicates that the 2-step RACH and the 4-step RACH of the first type of terminal share only the RO resources of the 4-step RACH of the second type of terminal.

[0081] In another exemplary embodiment, the same first indication parameter is configured for the 2-step RACH and the 4-step RACH of the first type of terminal. For example, in the case of a 1-bit indication parameter, if the 1-bit indication parameter is "0", it indicates that the 2-step RACH and the 4-step RACH of the first type of terminal share only the RO resources of the 4-step RACH of the second type of terminal; if the 1-bit indication parameter is "1", it indicates that the 2-step RACH and the 4-step RACH of the first type of terminal share only the RO resources of the 2-step RACH of the second type of terminal.

[0082] In an exemplary embodiment, the same first indication parameter is configured for the 2-step RACH and the 4-step RACH of the first type of terminal. For example, in the case of a 2-bit indication parameter, if the 2-bit indication parameter is "01", it indicates that the 2-step RACH and the 4-step RACH of the first type of terminal share only the RO resources of the 2-step RACH of the second type of terminal; if the 2-bit indication parameter is "10", it indicates that the 2-step RACH and the 4-step RACH of the first type of terminal share only the RO resources of the 4-step RACH of the second type of terminal; if the 2-bit indication parameter is "11", it indicates that the 2-step RACH and the 4-step RACH of the first type of terminal share both the RO resources of the 4-step RACH of the second type of terminal and the RO resources of the 2-step RACH of the second type of terminal.

[0083] In another exemplary embodiment, the same first indication parameter is configured for the 2-step RACH and the 4-step RACH of the first type of terminal. For example, in the case of a 2-bit indication parameter, if the 2-bit indication parameter is "10", it indicates that the 2-step RACH and the 4-step RACH of the first type of terminal share only the RO resources of the 4-step RACH of the second type of terminal; if the 2-bit indication parameter is "01", it indicates that the 2-step RACH and the 4-step RACH of the first type of terminal share only the RO resources of the 2-step RACH of the second type of terminal; similarly, if the 2-bit indication parameter is "11", it indicates that the 2-step RACH and the 4-step RACH of the first type of terminal share both the RO resources of the 4-step RACH of the second type of terminal and the RO resources of the 2-step RACH of the second type of terminal.

[0084] In an exemplary embodiment, an independent second indication parameter is configured for the 2-step RACH and 4-step RACH of the first type of terminal, respectively. For example, when each is configured with a 1-bit indication parameter, if the 1-bit indication parameter of the 2-step RACH of the first type of terminal is "1", it indicates that the 2-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the second type of terminal; if the 1-bit indication parameter of the 2-step RACH of the first type of terminal is "0", it indicates that the 2-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal; if the 1-bit indication parameter of the 4-step RACH of the first type of terminal is "1", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the second type of terminal; if the 1-bit indication parameter of the 4-step RACH of the first type of terminal is "0", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal.

[0085] In another exemplary embodiment, an independent second indication parameter is configured for the 2-step RACH and 4-step RACH of the first type of terminal, respectively. For example, when each is configured with a 1-bit indication parameter, if the 1-bit indication parameter of the 2-step RACH of the first type of terminal is "0", the 2-step RACH of the first type of terminal is indicated to share the RO resources of the 2-step RACH of the second type of terminal; if the 1-bit indication parameter of the 2-step RACH of the first type of terminal is "1", the 2-step RACH of the first type of terminal is indicated to share the RO resources of the 4-step RACH of the second type of terminal; if the 1-bit indication parameter of the 4-step RACH of the first type of terminal is "0", the 4-step RACH of the first type of terminal is indicated to share the RO resources of the 2-step RACH of the second type of terminal; if the 1-bit indication parameter of the 4-step RACH of the first type of terminal is "1", the 4-step RACH of the first type of terminal is indicated to share the RO resources of the 4-step RACH of the second type of terminal.

[0086] In an exemplary embodiment, an independent second indication parameter is configured for each of the 2-step RACH and 4-step RACH of the first type of terminal. For example, when each is configured with a 2-bit indication parameter, if the 2-bit indication parameter of the 2-step RACH of the first type of terminal is "01", it indicates that the 2-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the second type of terminal; if the 2-bit indication parameter of the 2-step RACH of the first type of terminal is "10", it indicates that the 2-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal; if the 2-bit indication parameter of the 2-step RACH of the first type of terminal is "11", it indicates that the 2-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal and the RO resources of the 2-step RACH of the second type of terminal; if the 2-bit indication parameter of the 4-step RACH of the first type of terminal is "01", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the second type of terminal. The RO resources of the RACH, when the 2-bit indication parameter of the 4-step RACH of the first type of terminal is "10", indicate that the 4-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal; when the 2-bit indication parameter of the 4-step RACH of the first type of terminal is "11", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal and the RO resources of the 2-step RACH of the second type of terminal. Alternatively, it can be set in reverse.

[0087] In some embodiments, when an independent second indication parameter is configured for the 2-step RACH and 4-step RACH of the first type of terminal, and the second indication parameter is used to indicate that the 2-step RACH and 4-step RACH of the first type of terminal share only one of the RO resources of the 2-step RACH and 4-step RACH of the second type of terminal, a PRACH mask is configured for the 2-step RACH and 4-step RACH of the first type of terminal respectively; or, a PRACH mask is configured for different RACH methods of the first type of terminal.

[0088] It can be understood that configuring a separate PRACH mask for the 2-step RACH and 4-step RACH of the first type of terminal can be interpreted as configuring one PRACH mask for the 2-step RACH and another for the 4-step RACH of the first type of terminal. The different RACH methods of the first type of terminal include 4-step RACH and 2-step RACH; configuring a single PRACH mask for all different RACH methods of the first type of terminal can be understood as configuring a single PRACH mask for both the 4-step RACH and 2-step RACH of the first type of terminal.

[0089] In an exemplary embodiment, when an independent second indication parameter is configured for the 2-step RACH and 4-step RACH of the first type of terminal, and the second indication parameter is used to indicate that the 2-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the second type of terminal, and the 4-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal, a PRACH mask is configured for the 2-step RACH and 4-step RACH of the first type of terminal, respectively.

[0090] Specifically, the PRACH mask of the 2-step RACH of the first type of terminal is used to determine a subset of the RO resources of the 2-step RACH of the second type of terminal, and the determined subset of RO resources is shared with the 2-step RACH of the first type of terminal; the PRACH mask of the 4-step RACH of the first type of terminal is used to determine a subset of the RO resources of the 4-step RACH of the second type of terminal, and the determined subset of RO resources is shared with the 4-step RACH of the first type of terminal.

[0091] In an exemplary embodiment, when an independent second indication parameter is configured for the 2-step RACH and 4-step RACH of the first type of terminal, and the second indication parameter is used to indicate that the 2-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the second type of terminal, and the 4-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal, a PRACH mask is configured for the different RACH methods of the first type of terminal.

[0092] Specifically, the common PRACH mask for different RACH methods of the first type of terminal is used to determine a subset of the RO resources of the 2-step RACH of the second type of terminal, and the determined subset is shared with the 2-step RACH of the first type of terminal; and the common PRACH mask for different RACH methods of the first type of terminal is used to determine a subset of the RO resources of the 4-step RACH of the second type of terminal, and the determined subset is shared with the 4-step RACH of the first type of terminal.

[0093] In some embodiments, when the same first indication parameter is configured for the 2-step RACH and 4-step RACH of the first type of terminal, and the first indication parameter is used to indicate that the 2-step RACH and 4-step RACH of the first type of terminal share only one of the RO resources of the 2-step RACH and 4-step RACH of the second type of terminal, a PRACH mask is configured for the 2-step RACH and 4-step RACH of the first type of terminal respectively; or, a PRACH mask is configured for different RACH methods of the first type of terminal.

[0094] Specifically, when configuring the same first indication parameter for both the 2-step RACH and 4-step RACH of the first type of terminal, and the first indication parameter being used to indicate that the 2-step RACH and 4-step RACH of the first type of terminal share only one of the RO resources of the 2-step RACH and 4-step RACH of the second type of terminal, a PRACH mask is configured for each of the 2-step RACH and 4-step RACH of the first type of terminal. The PRACH masks of the 2-step RACH and 4-step RACH of the first type of terminal respectively indicate that the 2-step RACH and 4-step RACH of the first type of terminal share a portion of the RO resources of the 2-step RACH or a portion of the RO resources of the 4-step RACH of the second type of terminal.

[0095] It is understandable that a PRACH mask is configured for different RACH methods of the first type of terminal. This PRACH mask can determine a subset of the RO resources of the 2-step RACH of the second type of terminal or the RO resources of the 4-step RACH of the second type of terminal, and share the determined subset of RO resources with different RACH methods of the first type of terminal, including 2-step RACH and 4-step RACH.

[0096] In some embodiments, when an independent second indication parameter is configured for the 2-step RACH and 4-step RACH of the first type of terminal, and the second indication parameter is used to indicate that the 2-step RACH and 4-step RACH of the first type of terminal share at least one of the RO resources of the 2-step RACH and 4-step RACH of the second type of terminal, an independent PRACH mask is configured for the 2-step RACH and 4-step RACH of the first type of terminal; or, a PRACH mask is configured for different RACH methods of the first type of terminal; or, a PRACH mask is configured for each type of RO resource configuration; or, a PRACH mask is configured for the different RO resources shared by the different RACH methods of the first type of terminal: 2-step RACH and 4-step RACH.

[0097] In an exemplary embodiment, when the second indication parameter configured for the 2-step RACH of the first type of terminal indicates that the 2-step RACH of the first type of terminal can share the RO resources of the 4-step RACH and the 2-step RACH of the second type of terminal, and at the same time, the second indication parameter configured for the 4-step RACH of the first type of terminal indicates that the 4-step RACH of the first type of terminal can share the RO resources configured for the 4-step RACH of the second type of terminal, a PRACH mask is configured for different RACH methods of the first type of terminal.

[0098] The common PRACH mask for different RACH methods of the first type of terminal is used to determine the subset of RO resources of the 2-step RACH and 4-step RACH of the second type of terminal. For example, the PRACH mask determines the subset of even-numbered RO resources of the 2-step RACH and 4-step RACH of the second type of terminal, and shares the determined subset of even-numbered RO resources of the 4-step RACH and 2-step RACH of the second type of terminal with the 2-step RACH of the first type of terminal. At the same time, the determined subset of RO resources of the 4-step RACH of the second type of terminal is shared with the 4-step RACH of the first type of terminal.

[0099] In another exemplary embodiment, when the second indication parameter configured for the 2-step RACH of the first type of terminal indicates that the 2-step RACH of the first type of terminal can share the RO resources of the 4-step RACH and the 2-step RACH of the second type of terminal, and at the same time, the second indication parameter configured for the 4-step RACH of the first type of terminal indicates that the 4-step RACH of the first type of terminal can share the RO resources configured for the 4-step RACH of the second type of terminal, an independent PRACH mask is configured for the 2-step RACH and the 4-step RACH of the first type of terminal respectively.

[0100] Specifically, the PRACH mask configured for the 2-step RACH of the first type of terminal determines a subset of the RO resources of the 2-step RACH and 4-step RACH of the second type of terminal. For example, the PRACH mask determines a subset of the even number of RO resources of the 2-step RACH and 4-step RACH of the second type of terminal, and shares the determined subset of the even number of RO resources of the 4-step RACH and 2-step RACH of the second type of terminal with the 2-step RACH of the first type of terminal. At the same time, the PRACH mask configured for the 4-step RACH of the first type of terminal determines a subset of the RO resources of the 4-step RACH of the second type of terminal, and shares the determined subset of the RO resources of the 4-step RACH of the second type of terminal with the 4-step RACH of the first type of terminal.

[0101] In some embodiments, when the same first indication parameter is configured for the 2-step RACH and 4-step RACH of the first type of terminal, and the first indication parameter is used to indicate that the 2-step RACH and 4-step RACH of the first type of terminal share at least one of the RO resources of the 2-step RACH and 4-step RACH of the second type of terminal, an independent PRACH mask is configured for the 2-step RACH and 4-step RACH of the first type of terminal respectively; or, a PRACH mask is configured for different RACH methods of the first type of terminal; or, a PRACH mask is configured for each type of RO resource configuration; or, a PRACH mask is configured for the different RO resources shared by the different RACH methods of the first type of terminal: 2-step RACH and 4-step RACH respectively.

[0102] In some embodiments, when both the 2-step RACH resources of the second type of terminal and the 4-step RACH resources of the second type of terminal are configured, the protocol stipulates, the network side configures, or determines in any other way that the 2-step RACH and the 4-step RACH of the first type of terminal can only share the RO resources of the 4-step RACH of the second type of terminal; or, the protocol stipulates, the network side configures, or determines in any other way that the 2-step RACH resources of the first type of terminal can only share the RO resources of the 2-step RACH of the second type of terminal, and the 4-step RACH of the first type of terminal can only share the 4-step RO resources of the second type of terminal.

[0103] In some embodiments, a separate PRACH mask is configured for the 2-step RACH and the 4-step RACH of the first type of terminal, respectively; or, a single PRACH mask is configured for different RACH methods of the first type of terminal.

[0104] It can be understood that configuring a separate PRACH mask for the 2-step RACH and 4-step RACH of the first type of terminal can be interpreted as configuring one PRACH mask for the 2-step RACH and another for the 4-step RACH of the first type of terminal. The different RACH methods of the first type of terminal include 4-step RACH and 2-step RACH; configuring a single PRACH mask for all different RACH methods of the first type of terminal can be understood as configuring a single PRACH mask for both the 4-step RACH and 2-step RACH of the first type of terminal.

[0105] In an exemplary embodiment, when the 2-step RACH resources of the second type of terminal and the 4-step RACH resources of the second type of terminal are configured simultaneously, and the protocol specifies, the network side configures, or determines in any other way that the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal can only share the RO resources of the 4-step RACH of the second type of terminal, an independent PRACHmask is configured for the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal respectively.

[0106] Specifically, the PRACH mask of the 2-step RACH of the first type of terminal is used to determine a subset of the RO resources of the 4-step RACH of the second type of terminal, and the determined subset of RO resources is shared with the 2-step RACH of the first type of terminal; the PRACH mask of the 4-step RACH of the first type of terminal is used to determine a subset of the RO resources of the 4-step RACH of the second type of terminal, and the determined subset of RO resources is shared with the 4-step RACH of the first type of terminal.

[0107] In another exemplary embodiment, when the 2-step RACH resources of the second type of terminal and the 4-step RACH resources of the second type of terminal are configured simultaneously, and the protocol stipulates, the network side configures, or determines in any other way that the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal can only share the RO resources of the 4-step RACH of the second type of terminal, a PRACH mask is configured for the different RACH methods of the first type of terminal.

[0108] Among them, the common PRACH mask of different RACH methods of the first type of terminal is used to determine a subset of the RO resources of the 4-step RACH of the second type of terminal, and the determined subset is shared with the different RACH methods of the first type of terminal, including 2-step RACH and 4-step RACH.

[0109] In some embodiments, when configuring 4-step RACH resources for the second type of terminal and 2-step RACH resources for the first type of terminal, an indication message is provided to indicate that the network device indicates the PRACH resources shared by the 4-step RACH of the first type of terminal via a second signaling.

[0110] In this embodiment of the disclosure, the second signaling can be RMSI, RRC, DCI, MAC CE, OSI, or other signaling.

[0111] In some embodiments, the network device indicates the PRACH resources shared by the 4-step RACH of the first type of terminal through a second signaling, including: configuring an indication parameter for the 4-step RACH of the first type of terminal, the indication parameter being used to indicate that the 4-step RACH of the first type of terminal shares at least one of the RO resources of the 4-step RACH of the second type of terminal and the RO resources of the 2-step RACH of the first type of terminal.

[0112] The indicator parameter can be a 1-bit indicator parameter, or a 2-bit indicator parameter, etc.

[0113] In an exemplary embodiment, when the indication parameter is a 1-bit indication parameter, a 1-bit indication parameter is configured for the 4-step RACH of the first type of terminal. When the 1-bit indication parameter is "0", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal. When the 1-bit indication parameter is "1", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the second type of terminal; or, the opposite is true.

[0114] In an exemplary embodiment, when the indication parameter is a 2-bit indication parameter, a 2-bit indication parameter is configured for the 4-step RACH of the first type of terminal. When the 2-bit indication parameter is "01", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal. When the 2-bit indication parameter is "10", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the second type of terminal. When the 2-bit indication parameter is "11", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the second type of terminal and the RO resources of the 4-step RACH of the second type of terminal; or, the opposite is true.

[0115] In some embodiments, when configuring the 2-step RACH resources of the second type of terminal, the 4-step RACH resources of the second type of terminal, and the 2-step RACH resources of the first type of terminal, an indication message is provided to indicate that the network device indicates the PRACH resources shared by the 4-step RACH of the first type of terminal via a third signaling.

[0116] In this embodiment of the disclosure, the third signaling can be RMSI, RRC, DCI, MAC CE, OSI, or other signaling.

[0117] In some embodiments, the network device indicates the PRACH resources shared by the first type of terminals through third signaling, including: configuring an indication parameter for the 4-step RACH of the first type of terminals, the indication parameter being used to indicate that the 4-step RACH of the first type of terminals shares at least one of the RO resources of the 2-step RACH of the second type of terminals, the 4-step RACH resources of the second type of terminals, and the RO resources of the 2-step RACH of the first type of terminals.

[0118] The indicator parameter can be a 3-bit indicator parameter, or other parameters.

[0119] In an exemplary embodiment, when the indication parameter is a 3-bit indication parameter, a 3-bit indication parameter is configured for the 4-step RACH of the first type of terminal. When the 3-bit indication parameter is "001", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal. When the 3-bit indication parameter is "010", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the second type of terminal. When the 3-bit indication parameter is "100", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the first type of terminal. When the 3-bit indication parameter is "011", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of both the 4-step RACH of the second type of terminal and the RO resources of the 2-step RACH of the first type of terminal. When the 3-bit indication parameter is "101", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of both the 4-step RACH of the second type of terminal and the 2-step RACH of the first type of terminal. The RO resources of the RACH, when the 3-bit indication parameter is "110", indicate that the 4-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the second type of terminal and the RO resources of the 2-step RACH of the first type of terminal. When the 3-bit indication parameter is "111", it indicates that the 4-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the second type of terminal, the RO resources of the 2-step RACH of the second type of terminal, and the RO resources of the 2-step RACH of the first type of terminal. Alternatively, it can be set in reverse.

[0120] In some embodiments, when both the 4-step RACH resources of the second type of terminal and the 2-step RACH resources of the first type of terminal are configured, if the protocol specifies, the network side configures, or any other means determines that during the initial random access phase, configuring the 2-step RACH resources of the first type of terminal is not supported and the 4-step RACH resources of the first type of terminal are not configured; or, if the protocol specifies, the network side configures, or any other means determines that the 4-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the first type of terminal; or, if the protocol specifies, the network side configures, or any other means determines that the 4-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal.

[0121] In some embodiments, when the 2-step RACH resources of the second type of terminal, the 4-step RACH resources of the second type of terminal, and the 2-step RACH resources of the first type of terminal are configured simultaneously, if the protocol specifies, the network side configures, or any other means determines that the initial random access phase does not support configuring the 2-step RACH resources of the first type of terminal and therefore does not configure the 4-step RACH resources of the first type of terminal; or, if the protocol specifies, the network side configures, or any other means determines that the 4-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the first type of terminal; or, if the protocol specifies, the network side configures, or any other means determines that the 4-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal.

[0122] In some embodiments, when the 4-step RACH of the first type of terminal shares multiple RO resource configurations, a single PRACH mask is configured for all multiple RO resources; or, a single PRACH mask is configured for each type of RO resource configuration.

[0123] It is understandable that, in the case of the first type of terminal sharing multiple RO resource configurations in the 4-step RACH, a PRACH mask is configured for multiple RO resources. The PRACH mask configured for multiple RO resources is used to determine a subset of multiple RO resources, and the determined subset is shared with the 4-step RACH of the first type of terminal.

[0124] In some embodiments, when the 4-step RACH of the first type of terminal shares multiple RO resource configurations, a PRACH mask is configured for multiple RO resources. If multiple SSBs correspond to one RO resource in the first RO resource configuration, the PRACH mask is invalid for the first RO resource; or, the PRACH mask is invalid for all RO resources; or, the PRACH mask configured for multiple RO resources is not used.

[0125] In some embodiments, when configuring the resources of the first type of terminal and the 4-step RACH resources of the second type of terminal, an indication message is provided to indicate that the network device indicates the PRACH resources shared by the 2-step RACH of the first type of terminal via a fourth signaling.

[0126] In this embodiment of the disclosure, the fourth signaling can be RMSI, RRC, DCI, MAC CE, OSI, or other signaling.

[0127] In some embodiments, the network device indicates the PRACH resources shared by the 2-step RACH of the first type of terminal through a fourth signaling, including: configuring an indication parameter for the 2-step RACH of the first type of terminal, the indication parameter being used to indicate that the 2-step RACH of the first type of terminal shares at least one of the RO resources of the 4-step RACH of the second type of terminal and the RO resources of the 4-step RACH of the first type of terminal.

[0128] In some embodiments, when configuring 4-step RACH resources for a first type of terminal, 2-step RACH resources for a second type of terminal, and 4-step RACH resources for a second type of terminal, an indication message is provided to indicate that the network device indicates the PRACH resources shared by the 2-step RACH of the first type of terminal via a fifth signaling.

[0129] In this embodiment of the disclosure, the fifth signaling can be RMSI, RRC, DCI, MAC CE, OSI, or other signaling.

[0130] In some embodiments, the network device indicates the PRACH resources shared by the 2-step RACH of the first type of terminal through the fifth signaling, including: configuring an indication parameter for the 2-step RACH of the first type of terminal, the indication parameter being used to indicate that the 2-step RACH of the first type of terminal shares at least one of the RO resources of the 4-step RACH of the second type of terminal, the RO resources of the 2-step RACH of the second type of terminal, and the RO resources of the 4-step RACH of the first type of terminal.

[0131] In some embodiments, when both the 4-step RACH resources of the first type of terminal and the 4-step RACH resources of the second type of terminal are configured, the protocol specifies, the network side configures, or any other means determines that the 2-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal; or, the 2-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the first type of terminal.

[0132] In some embodiments, when the 4-step RACH resources of the first type of terminal, the 2-step RACH resources of the second type of terminal, and the 4-step RACH resources of the second type of terminal are configured simultaneously, the protocol specifies, the network side configures, or any other means determines that the 2-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the first type of terminal; or, the protocol specifies, the network side configures, or any other means determines that the 2-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the second type of terminal; or, the protocol specifies, the network side configures, or any other means determines that the 2-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal.

[0133] In some embodiments, when the 4-step RACH of the first type of terminal shares multiple RO resource configurations, a single PRACH mask is configured for all multiple RO resources; or, a single PRACH mask is configured for each type of RO resource configuration.

[0134] In some embodiments, when a PRACH mask is configured for multiple RO resources, if multiple SSBs correspond to one RO resource in the first RO resource configuration, the PRACH mask is invalid for the first RO resource; or, the PRACH mask is invalid for all RO resources; or, the PRACH mask configured for multiple RO resources is not used.

[0135] In some embodiments, when an SSB corresponds to multiple RO resources, the RO resources of different random access resource configurations are jointly encoded, and one or more of the RO resources are indicated by codepoints or bitmaps as RO resources shared by the 2-step RACH and 4-step RACH of the first type of terminal.

[0136] It is understood that in this embodiment of the disclosure, when one SSB corresponds to multiple RO resources, the RO resources of different random access resource configurations are jointly encoded, and one or more RO resources are indicated by codepoint or bitmap as RO resources shared by the 2-step RACH and 4-step RACH of the first type of terminal. In this way, the RO configuration indication field under the original different RACH methods can be cancelled.

[0137] In some embodiments, random access resource configuration includes: configuring only the 4-step RACH resources of the second type of terminal; or, configuring the 2-step RACH resources of the second type of terminal and the 4-step RACH resources of the second type of terminal; or, configuring the 4-step RACH resources of the second type of terminal and the 2-step RACH resources of the first type of terminal; or, configuring the 2-step RACH resources of the second type of terminal, the 4-step RACH resources of the second type of terminal, and the 2-step RACH resources of the first type of terminal; or, configuring the 4-step RACH resources of the first type of terminal and the 4-step RACH resources of the second type of terminal; or, configuring the 4-step RACH resources of the first type of terminal, the 2-step RACH resources of the second type of terminal, and the 4-step RACH resources of the second type of terminal.

[0138] In an exemplary embodiment, the random access resource configuration is as follows: the 2-step RACH resources of the second type of terminal, the 4-step RACH resources of the second type of terminal, and the 4-step RACH resources of the first type of terminal are configured. The 2-step RACH of the first type of terminal can share the RO resources under the other three resource configurations, and the following conditions are met: the SSB to RO resource mapping relationship of the 4-step RACH of the first type of terminal is 1:2, the SSB to RO mapping relationship of the 4-step RACH of the second type of terminal is 1:4, and the SSB to RO mapping relationship of the 2-step RACH of the second type of terminal is 1:2.

[0139] The 2-step RACH of the first type of terminal can share resources under three configurations. Therefore, it can be indicated in bitmap form, for example, using 8 bits to indicate: "11001000". Here, the first two "11" indicate that the 2-step RACH of the first type of terminal can share all ROs of the 4-step RACH of the first type of terminal. The next four "0010" indicate that the 2-step RACH of the first type of terminal can share the third RO resource of the 4-step RACH of the second type of terminal. The last two "00" indicate that the 2-step RACH of the first type of terminal does not share the RO resources of the 2-step RACH of the second type of terminal.

[0140] Similarly, codepoints can also be used for instructions.

[0141] In some embodiments, where an SSB corresponds to multiple RO resources and the first type of terminal shares at least a portion of the PRACH resources of the second type of terminal, the protocol specifies, the network side configures, or otherwise determines to configure different PRACH mask values ​​for different characteristics of the first type of terminal and / or the second type of terminal.

[0142] It is understandable that when an SSB corresponds to multiple RO resources, and a Type 1 terminal shares at least a portion of the PRACH resources of a Type 2 terminal—for example, when the 2-step RACH and 4-step RACH of the Type 1 terminal share the RO resources of the 4-step RACH of the Type 2 terminal with the 2-step RACH of the Type 2 terminal—to avoid excessive division of the preamble for the same RO resource, different PRACH mask values ​​can be configured according to the protocol, network-side configuration, or any other method. In an exemplary embodiment, the different features of the Type 1 terminal and / or the Type 2 terminal may also include: SDT (small data transmission), slice, coverage enhancement, small packet transmission, and network slicing.

[0143] In some embodiments, when one SSB corresponds to multiple RO resources, a fifth PRACH mask is configured to correspond to two shared RO indexes.

[0144] It is understood that the RO subset configuration table can be further enhanced in this embodiment of the disclosure, as shown in Table 1 below. Reserved bits 11-14 of the RO subset indicator are set to include RO indices that allow sharing between two ROs, and a fifth PRACH mask is configured corresponding to the two shared RO indices. The number of fifth PRACH masks can be one or more.

[0145] Table 1:

[0146] RO subset instruction Shared RO index 0 All RO 1 RO Index 1 2 RO Index 2 3 RO Index 3 4 RO Index 4 5 RO Index 5 6 RO Index 6 7 RO Index 7 8 RO Index 8 9 RO of even index 10 RO of odd index 11 1～2 12 3～4 13 5～6 14 7～8 15 Reserved bits

[0147] In some embodiments, a fifth PRACH mask is configured for the first type of terminal, wherein the 2-step RACH of the first type of terminal shares the RO resources of the even-numbered index of the two RO indices, and the 4-step RACH of the first type of terminal shares the RO resources of the odd-numbered index of the two RO indices; or, the 2-step RACH of the first type of terminal shares the RO resources of the odd-numbered index of the two RO indices, and the 4-step RACH of the first type of terminal shares the RO resources of the even-numbered index of the two RO indices.

[0148] In some embodiments, the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal are instructed by indication signaling to share the RO resources of the two RO indices.

[0149] In the exemplary embodiment, indication is given through indication signaling. One SSB corresponds to N RO resources, and N bits are set accordingly. "0" indicates that it cannot be used for sharing by the first type of terminal, and "1" indicates that it can be used for sharing by the first type of terminal. Alternatively, it can be set in reverse.

[0150] In some embodiments, the current cell only supports 2-step RACH for the first type of terminal and the second type of terminal. When only the 2-step RACH resources of the second type of terminal are configured, the protocol specifies, the network side configures, or determines in any other way that the 2-step RACH of the first type of terminal shares the 2-step RACH resources of the second type of terminal.

[0151] It is understandable that the current cell only supports 2-step RACH for both Type I and Type II terminals, and Type I and Type II terminals can only use 2-step RACH for random access in the current cell.

[0152] In some embodiments, when an SSB corresponds to multiple RO resources, a PRACH mask is configured for the 2-step RACH of the first type of terminal. The PRACH mask is used to determine a subset of the RO resources of the 2-step RACH of the second type of terminal and to share the subset of RO resources with the 2-step RACH of the first type of terminal.

[0153] Understandably, when only the 2-step RACH resources of the second type of terminal are configured, and the protocol specifies, the network side configures, or determines in any other way that the 2-step RACH of the first type of terminal shares the resources of the 2-step RACH of the second type of terminal, a PRACH mask is configured for the 2-step RACH of the first type of terminal. This PRACH mask determines a subset of the RO resources of the 2-step RACH of the second type of terminal, and shares the subset of RO resources with the 2-step RACH of the first type of terminal, thereby indicating the PRACH resources shared by the 2-step RACH of the first type of terminal.

[0154] In some embodiments, the current cell only supports 4-step RACH for the first type of terminal and the second type of terminal. When only the 4-step RACH resources of the second type of terminal are configured, the protocol stipulates, the network side configures, or determines in any other way that the 4-step RACH of the first type of terminal shares the 4-step RACH resources of the second type of terminal.

[0155] It is understandable that the current cell only supports 4-step RACH for both Type I and Type II terminals, and Type I and Type II terminals can only use 4-step RACH for random access in the current cell.

[0156] In some embodiments, when an SSB corresponds to multiple RO resources, a PRACH mask is configured for the 4-step RACH of the first type of terminal. The PRACH mask is used to determine a subset of the RO resources of the 4-step RACH of the second type of terminal and to share the subset of RO resources with the 4-step RACH of the first type of terminal.

[0157] Understandably, when only the 4-step RACH resources of the second type of terminal are configured, and the protocol specifies, the network side configures, or determines in any other way that the 4-step RACH of the first type of terminal shares the resources of the 4-step RACH of the second type of terminal, a PRACH mask is configured for the 4-step RACH of the first type of terminal. This PRACH mask determines a subset of the RO resources of the 4-step RACH of the second type of terminal, and shares the subset of RO resources with the 4-step RACH of the first type of terminal, thereby indicating the PRACH resources shared by the 4-step RACH of the first type of terminal.

[0158] For a second aspect of the embodiments of this disclosure, please refer to Figure 3 , Figure 3This is a flowchart illustrating a resource allocation method provided in an embodiment of this disclosure.

[0159] like Figure 3 As shown, this method is executed by a first-type terminal, and the method may include, but is not limited to, the following steps:

[0160] S10: Receive instruction information for network device configuration.

[0161] S20: Based on the instruction information, obtain the Physical Random Access Channel (PRACH) resources shared by the first type of terminals.

[0162] The first type of terminal can be a Redcap terminal.

[0163] In this embodiment of the disclosure, the first type of terminal receives the indication information configured by the network device, and obtains the Physical Random Access Channel (PRACH) resources shared by the first type of terminal according to the indication information. By implementing this embodiment of the disclosure, the shared PRACH resources can be configured for the first type of terminal, so that the first type of terminal can give advance indication through different preamble sequences in the shared RO resources and report its terminal type to the network device. This enables the first type of terminal to achieve better link adaptation during random access, so as to configure more suitable resource unit (RE) resources, MCS level, etc. for the first type of terminal.

[0164] In some embodiments, when only the 4-step RACH resources of the second type of terminal are configured, the protocol specifies, the network side configures, or determines in any other way that the 4-step RACH resources of the second type of terminal are shared by the random access RACH method of the first type of terminal; wherein, the random access RACH method of the first type of terminal includes at least one of the following: 4-step RACH; 2-step RACH.

[0165] In some embodiments, the 4-step RACH of the first type of terminal, the 2-step RACH of the first type of terminal, and the 4-step RACH of the second type of terminal share the same random access opportunity (RO) resources.

[0166] In some embodiments, when a synchronization signal block SSB corresponds to multiple RO resources, the receiving network device configures a PRACH mask for the 2-step RACH and 4-step RACH of the first type of terminal. The PRACH mask is used to determine the RO subset of the 4-step RACH of the second type of terminal. The RO subset is shared with the 4-step RACH and 2-step RACH of the first type of terminal.

[0167] In some embodiments, when an SSB corresponds to RO resources, the receiving network device is configured with a first PRACH mask and a second PRACH mask for the 2-step RACH and 4-step RACH of the first type of terminal, respectively; the first PRACH mask is used to determine a first subset of the RO resources of the 4-step RACH of the second type of terminal and share the first subset with the 4-step RACH of the first type of terminal; the second PRACH mask is used to determine a second subset of the RO resources of the 4-step RACH of the second type of terminal and share the second subset with the 2-step RACH of the first type of terminal.

[0168] In some embodiments, when one SSB corresponds to multiple RO resources, the receiving network device configures a third PRACH mask and a fourth PRACH mask for the 2-step RACH and 4-step RACH of the first type of terminal, respectively; the third PRACH mask is used to determine a third subset of the RO resources of the 4-step RACH of the second type of terminal and share the third subset with the 4-step RACH of the first type of terminal; the fourth PRACH mask is used to determine a fourth subset of the RO resources of the 4-step RACH of the first type of terminal and share the fourth subset with the 2-step RACH of the first type of terminal.

[0169] In some embodiments, when an SSB corresponds to multiple RO resources, when a PRACH mask is received from the network device for the 4-step RACH of the first type of terminal, but no PRACH mask is configured for the 2-step RACH of the first type of terminal, the 2-step RACH of the first type of terminal uses the same RO resources as the 4-step RACH of the first type of terminal or uses the same RO resources as the 4-step RACH of the second type of terminal.

[0170] In some embodiments, when an SSB corresponds to multiple RO resources, when a PRACH mask is received from the network device for the 2-step RACH of a first-type terminal but not for the 4-step RACH of the first-type terminal, the 4-step RACH of the first-type terminal uses the same RO resources as the 2-step RACH of the first-type terminal; or, it uses the same RO resources as the 4-step RACH of the second-type terminal; or, it does not support configuring a PRACH mask for the 2-step RACH of the first-type terminal, but does not configure a PRACH mask for the 4-step RACH of the first-type terminal.

[0171] In some embodiments, when configuring the 2-step RACH resources of the second type of terminal and the 4-step RACH resources of the second type of terminal, according to the instruction information: receiving the first signaling from the network device, the first type of terminal shares at least a portion of the RACH resources of the second type of terminal.

[0172] In some embodiments, receiving first signaling from a network device, wherein a first type of terminal shares at least a portion of the PRACH resources of a second type of terminal, includes: receiving the same first indication parameter configured by the network device for the 2-step RACH and 4-step RACH of the first type of terminal; or receiving two independent second indication parameters configured by the network device for the 2-step RACH and 4-step RACH of the first type of terminal, respectively.

[0173] In some embodiments, according to a first indication parameter or a second indication parameter, the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal share only one of the RO resources of the 2-step RACH of the second type of terminal and the RO resources of the 4-step RACH of the second type of terminal; or, according to the first indication parameter or the second indication parameter, the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal share at least one of the RO resources of the 2-step RACH of the second type of terminal and the RO resources of the 4-step RACH of the second type of terminal.

[0177] In some embodiments, when the network device receives the same first indication parameter configured for the 2-step RACH and 4-step RACH of the first type of terminal, and according to the first indication parameter, the 2-step RACH and 4-step RACH of the first type of terminal share at least one of the RO resources of the 2-step RACH and 4-step RACH of the second type of terminal, the network device receives two independent PRACH masks configured for the 2-step RACH and 4-step RACH of the first type of terminal respectively; or, the network device receives a PRACH mask configured jointly for different RACH methods of the first type of terminal; or, the network device receives a PRACH mask configured for each type of RO resource configuration; or, the network device receives a PRACH mask configured for different RACH methods of the first type of terminal: 2-step RACH and 4-step RACH respectively.

[0178] In some embodiments, when both the 2-step RACH resources of the second type of terminal and the 4-step RACH resources of the second type of terminal are configured, the protocol stipulates, the network side configures, or determines in any other way that the 2-step RACH and the 4-step RACH of the first type of terminal can only share the RO resources of the 4-step RACH of the second type of terminal; or, the protocol stipulates, the network side configures, or determines in any other way that the 2-step RACH resources of the first type of terminal can only share the RO resources of the 2-step RACH of the second type of terminal, and the 4-step RACH of the first type of terminal can only share the 4-step RO resources of the second type of terminal.

[0188] In some embodiments, when the 4-step RACH of the first type of terminal shares multiple RO resource configurations, the receiving network device provides a PRACH mask for multiple RO resources. If multiple SSBs correspond to one RO resource in the first RO resource configuration, the PRACH mask is invalid for the first RO resource; or, the PRACH mask is invalid for all RO resources; or, the receiving network device does not use the PRACH mask for multiple RO resources.

[0189] In some embodiments, when configuring the resources of the first type of terminal and the 4-step RACH resources of the second type of terminal, an indication message is provided to indicate that the network device indicates the PRACH resources shared by the 2-step RACH of the first type of terminal via a fourth signaling.

[0196] In some embodiments, when the 4-step RACH resources of the first type of terminal, the 2-step RACH resources of the second type of terminal, and the 4-step RACH resources of the second type of terminal are configured simultaneously, the protocol specifies, the network side configures, or determines in any other way that the 2-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the first type of terminal; or, the protocol specifies, the network side configures, or determines in any other way that the 2-step RACH of the first type of terminal shares the RO resources of the 2-step RACH of the second type of terminal; or, the protocol specifies, the network side configures, or determines in any other way that the 2-step RACH of the first type of terminal shares the RO resources of the 4-step RACH of the second type of terminal.

[0197] In some embodiments, when the 4-step RACH of the first type of terminal shares multiple RO resource configurations, a PRACH mask configured by the network device for multiple RO resources is received; or, a PRACH mask configured by the network device for each RO resource configuration is received.

[0198] In some embodiments, when receiving a PRACH mask that is jointly configured by the network device for multiple RO resources, if multiple SSBs correspond to one RO resource in the first RO resource configuration, the PRACH mask is invalid for the first RO resource; or, the PRACH mask is invalid for all RO resources; or, the PRACH mask that is jointly configured by the network device for multiple RO resources is not used.

[0199] In some embodiments, when an SSB corresponds to multiple RO resources, the RO resources of different random access resource configurations are jointly encoded, and one or more RO resources indicated by the receiving network device through codepoints or bitmaps are RO resources shared by the 2-step RACH and 4-step RACH of the first type of terminal.

The receiving network device indicates through codepoints or bitmaps that one or more of the RO resources are RO resources shared by the 2-step RACH and 4-step RACH of the first type of terminal. In this method, the RO configuration indication field under the original different RACH methods can be cancelled.

[0201] In some embodiments, random access resource configuration includes: configuring only the 4-step RACH resources of the second type of terminal; or, configuring the 2-step RACH resources of the second type of terminal and the 4-step RACH resources of the second type of terminal; or, configuring the 4-step RACH resources of the second type of terminal and the 2-step RACH resources of the first type of terminal; or, configuring the 2-step RACH resources of the second type of terminal, the 4-step RACH resources of the second type of terminal, and the 2-step RACH resources of the first type of terminal; or, configuring the 4-step RACH resources of the first type of terminal and the 4-step RACH resources of the second type of terminal; or, configuring the 4-step RACH resources of the first type of terminal, the 2-step RACH resources of the second type of terminal, and the 4-step RACH resources of the second type of terminal.

[0202] In an exemplary embodiment, the random access resource configuration is as follows: the 2-step RACH resources of the second type of terminal, the 4-step RACH resources of the second type of terminal, and the 4-step RACH resources of the first type of terminal are configured. The 2-step RACH of the first type of terminal can share the RO resources under the other three resource configurations, and the following conditions are met: the SSB to RO resource mapping relationship of the 4-step RACH of the first type of terminal is 1:2, the SSB to RO mapping relationship of the 4-step RACH of the second type of terminal is 1:4, and the SSB to RO mapping relationship of the 2-step RACH of the second type of terminal is 1:2.

[0203] The 2-step RACH of the first type of terminal can share resources under three configurations. Therefore, it can be indicated in bitmap form, for example, using 8 bits to indicate: "11001000". Here, the first two "11" indicate that the 2-step RACH of the first type of terminal can share all ROs of the 4-step RACH of the first type of terminal. The next four "0010" indicate that the 2-step RACH of the first type of terminal can share the third RO resource of the 4-step RACH of the second type of terminal. The last two "00" indicate that the 2-step RACH of the first type of terminal does not share the RO resources of the 2-step RACH of the second type of terminal.

[0204] Similarly, codepoints can also be used for instructions.

[0205] In some embodiments, where an SSB corresponds to multiple RO resources and the first type of terminal shares at least a portion of the PRACH resources of the second type of terminal, the protocol specifies, the network side configures, or determines in any other way that different PRACH mask values ​​are configured for different characteristics of the first type of terminal and / or the second type of terminal.

[0206] It is understandable that when an SSB corresponds to multiple RO resources, and the first type of terminal shares at least part of the PRACH resources of the second type of terminal, for example, when the 2-step RACH and 4-step RACH of the first type of terminal share the RO resources of the 4-step RACH of the second type of terminal with the 2-step RACH of the second type of terminal, in order to avoid excessive division of the preamble of the same RO resource, different PRACH mask values ​​can be determined by protocol specification, network side configuration, or any other means.

[0207] In some embodiments, when one SSB corresponds to multiple RO resources, a fifth PRACH mask is configured to correspond to two shared RO indexes.

[0208] It is understood that the RO subset configuration table can be further enhanced in this embodiment of the disclosure, as shown in Table 1 below. Reserved bits 11-14 of the RO subset indicator are set to include RO indices that allow sharing between two ROs, and a fifth PRACH mask is configured corresponding to the two shared RO indices. The number of fifth PRACH masks can be one or more.

[0209] Table 1:

[0210] RO subset instruction Shared RO index 0 All RO 1 RO Index 1 2 RO Index 2 3 RO Index 3 4 RO Index 4 5 RO Index 5 6 RO Index 6 7 RO Index 7 8 RO Index 8 9 RO of even index 10 RO of odd index 11 1～2 12 3～4 13 5～6 14 7～8 15 Reserved bits

[0211] In some embodiments, the network device receives a fifth PRACH mask configured for a first type of terminal, wherein the 2-step RACH of the first type of terminal shares the RO resources of the even-numbered index of the two RO indices, and the 4-step RACH of the first type of terminal shares the RO resources of the odd-numbered index of the two RO indices; or, the 2-step RACH of the first type of terminal shares the RO resources of the odd-numbered index of the two RO indices, and the 4-step RACH of the first type of terminal shares the RO resources of the even-numbered index of the two RO indices.

[0212] In some embodiments, the indication signaling sent by the network device is obtained, and the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal share the RO resources of two RO indexes.

[0213] In the exemplary embodiment, the indication signaling sent by the network device is obtained. One SSB corresponds to N RO resources, and N bits are set accordingly. "0" indicates that it cannot be used for sharing by the first type of terminal, and "1" indicates that it can be used for sharing by the first type of terminal. Alternatively, it can be set in reverse.

[0214] In some embodiments, the current cell only supports 2-step RACH for the first type of terminal and the second type of terminal. When only the 2-step RACH resources of the second type of terminal are configured, the protocol stipulates, the network side configures, or determines in any other way that the 2-step RACH of the first type of terminal shares the 2-step RACH resources of the second type of terminal.

[0215] It is understandable that the current cell only supports 2-step RACH for both Type I and Type II terminals, and Type I and Type II terminals can only use 2-step RACH for random access in the current cell.

[0216] In some embodiments, when an SSB corresponds to multiple RO resources, a PRACH mask is received by the network device for the 2-step RACH of the first type of terminal. The PRACH mask is used to determine a subset of the RO resources of the 2-step RACH of the second type of terminal and to share the subset of RO resources with the 2-step RACH of the first type of terminal.

[0217] Understandably, when only the 2-step RACH resources of the second type of terminal are configured, and the protocol specifies, the network side configures, or determines in any other way that the 2-step RACH of the first type of terminal shares the resources of the 2-step RACH of the second type of terminal, the receiving network device configures a PRACH mask for the 2-step RACH of the first type of terminal. This PRACH mask determines a subset of the RO resources of the 2-step RACH of the second type of terminal, and shares the subset of RO resources with the 2-step RACH of the first type of terminal, thereby enabling the 2-step RACH of the first type of terminal to acquire the shared PRACH resources.

[0218] In some embodiments, the current cell only supports 4-step RACH for the first type of terminal and the second type of terminal. When only the 4-step RACH resources of the second type of terminal are configured, the protocol stipulates, the network side configures, or determines in any other way that the 4-step RACH of the first type of terminal shares the 4-step RACH resources of the second type of terminal.

[0219] It is understandable that the current cell only supports 4-step RACH for both Type I and Type II terminals, and Type I and Type II terminals can only use 4-step RACH for random access in the current cell.

[0220] In some embodiments, when an SSB corresponds to multiple RO resources, a PRACH mask is received by the network device for the 4-step RACH of the first type of terminal. The PRACH mask is used to determine a subset of the RO resources of the 4-step RACH of the second type of terminal and to share the subset of RO resources with the 4-step RACH of the first type of terminal.

[0221] Understandably, when only the 4-step RACH resources of the second type of terminal are configured, and the protocol specifies, the network side configures, or determines in any other way that the 4-step RACH of the first type of terminal shares the resources of the 4-step RACH of the second type of terminal, the receiving network device configures a PRACH mask for the 4-step RACH of the first type of terminal. This PRACH mask determines a subset of the RO resources of the 4-step RACH of the second type of terminal, and shares the subset of RO resources with the 4-step RACH of the first type of terminal, thereby enabling the 4-step RACH of the first type of terminal to acquire the shared PRACH resources.
