[0039] It should be noted that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It can be known by those skilled in the art that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0040] The resource allocation method and device provided by the present disclosure will be described in detail below in combination with the accompanying drawings.

[0041] At present, the Internet of Things is developing rapidly, which brings many conveniences to human life and work. Among them, machine type communication technology (MTC) and narrowband Internet of Things technology (NB-IoT) are typical representatives of cellular Internet of Things technology. At present, these technologies have been widely used in smart cities (such as meter reading), smart agriculture (such as temperature and humidity information collection), and smart transportation (such as shared bicycles) and many other fields.

[0042] For low-rate high-latency scenarios (such as meter reading, environmental monitoring, etc.) in Internet of Things services, related technologies propose two technologies of MTC and NB-IoT. Currently, NB-IoT technology can support a rate of several hundred K at most, and MTC can support a rate of several M at most. However, with the continuous development of Internet of Things services (such as monitoring, smart home, wearable devices, and industrial sensor detection services), generally tens to hundreds of M rate are required, and the requirement for latency is also relatively high. Therefore, in the communication system, the two technologies of MTC and NB-IoT cannot meet the current requirements of Internet of Things services.

[0043] Meanwhile, in another aspect, MTC and NB-IoT are generally deployed in scenarios such as basements, fields, and the like where it is not easy to charge or replace batteries, and thus terminals associated with MTC and NB-IoT are subject to hardware limitations, resulting in less coverage capability than general wireless communication terminals. Moreover, due to the influence of the application environment, power saving of the device is also a characteristic of MTC and NB-IoT. Based on this situation, a new type of user equipment is proposed to be redesigned in 5G NR to cover the requirements of such mid-end Internet of Things devices. In the current 3GPP (3rd generation partnership project) standardization, this new terminal type is called reduced capability (Redcap) terminal or simply NR-lite.

[0044] In the current Rel-17 discussion, it is supported to configure the same initial downlink / uplink bandwidth part (initial DL / UL BWP) for redcap terminals and non-redcap terminals. At the same time, in order to achieve better link adaptation in the random access process, that is, to configure more suitable RE (resource element) resources, MCS (modulation and coding scheme) levels, and the like for redcap terminals, it is necessary to configure PRACH resources for redcap terminals to enable early identification of redcap terminals and report their terminal types.

[0045] Based on this, the embodiments of the present disclosure provide a resource allocation method and device to at least configure PRACH resources for redcap terminals.

[0046] Please refer to Figure 2 , Figure 2 is a flowchart of a resource allocation method provided by the embodiments of the present disclosure.

[0047] As Figure 2 indicated, the method is performed by a network device, and the method can include but is not limited to the following steps: S1: configuring indication information for a first type of terminal, wherein the indication information is used to indicate a physical random access channel (PRACH) resource shared by the first type of terminal.

[0048] The first type of terminal can be a redcap terminal.

[0049] In the embodiments of the present disclosure, the network device configures the indication information for the first type of terminal, and indicates the PRACH resource shared by the first type of terminal. By implementing the embodiments of the present disclosure, the PRACH resource shared by the first type of terminal 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 resource to perform early indication and report the terminal type to the network device, so that the first type of terminal can realize better link adaptation in the random access process, and more suitable resource units RE resources, MCS (modulation and coding scheme) levels, etc. are configured for the first type of terminal.

[0050] It should be noted that the first type of terminal can share the PRACH resource of the second type of terminal, wherein the network device can only configure RO (RACH occasion, random access occasion) resource for the four-step random access 4-step RACH of the second type of terminal, or only configure RO (RACH occasion, random access occasion) resource for the four-step random access 4-step RACH of the second type of terminal, or configure different RO (RACH occasion, random access occasion) resources for the two-step random access 2-step RACH and the four-step random access 4-step RACH of the second type of terminal, and the first type of terminal can support 2-step RACH, or support 4-step RACH, or support both 2-step RACH and 4-step RACH. Therefore, in the case that the current cell supports both 2-step RACH and 4-step RACH for the first type of terminal and the second type of terminal, the PRACH resource shared by the first type of terminal has multiple possibilities.

[0051] In some embodiments, in the case of only configuring the four-step random access 4-step RACH resource of the second type of terminal, the protocol stipulates or the network side configures or any other way determines that the random access RACH mode of the first type of terminal shares the resource of the 4-step RACH of the second type of terminal; wherein the random access RACH mode of the first type of terminal includes at least one of the following: four-step random access 4-step RACH; two-step random access 2-step RACH.

[0052] It can be understood that the random access mode of the first type of terminal includes 2-step RACH and 4-step RACH, and the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal can share the 4-step RACH resource of the second type of terminal at the same time in the case of only configuring the 4-step RACH resource of the second type of terminal.

[0053] 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 occasion RO resource.

[0054] It can be understood that, in the case that 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 resource of the second type of terminal, the three can share the same RO resource.

[0055] In some embodiments, in the case that one synchronization signal block SSB corresponds to multiple RO resources, one PRACH parameter (for example, the PRACH parameter can be 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, and the PRACH mask is used to determine a subset of ROs of the 4-step RACH of the second type of terminal, and the subset of ROs is shared by the 4-step RACH of the first type of terminal and the 2-step RACH of the first type of terminal. In the embodiments of the present disclosure, the PRACH mask is taken as an example for description; however, it can be understood by those skilled in the art that other PRACH parameters can also be used.

[0056] In an exemplary embodiment, in the case that one SSB corresponds to 8 RO resources, one 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, and the PRACH mask is used to determine a subset of ROs of the 4-step RACH of the second type of terminal, for example, even-numbered ROs of the 8 RO resources, and then the even-numbered ROs are shared by the 4-step RACH of the first type of terminal and the 2-step RACH of the first type of terminal.

[0057] In another exemplary embodiment, in the case that one SSB corresponds to 8 RO resources, one 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, and the PRACH mask is used to determine a subset of ROs of the 4-step RACH of the second type of terminal, for example, odd-numbered ROs of the 8 RO resources, and then the odd-numbered ROs are shared by the 4-step RACH of the first type of terminal and the 2-step RACH of the first type of terminal.

[0058] In some embodiments, in case one SSB corresponds to multiple RO resources, a first PRACH mask and a second PRACH mask are configured for the 2-step RACH of the first type of terminals and the 4-step RACH of the first type of terminals, respectively; the first PRACH mask is used to determine a first subset of the RO resources for the 4-step RACH of the second type of terminals, and the first subset is shared to the 4-step RACH of the first type of terminals; the second PRACH mask is used to determine a second subset of the RO resources for the 4-step RACH of the second type of terminals, and the second subset is shared to the 2-step RACH of the first type of terminals.

[0059] In an example embodiment, in case one 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 terminals and the 4-step RACH of the first type of terminals, respectively; the first PRACH mask is used to determine a first subset of the 8 RO resources for the 4-step RACH of the second type of terminals, e.g., odd RO resources, and the first subset (odd RO resources) is shared to the 4-step RACH of the first type of terminals; the second PRACH mask is used to determine a second subset of the RO resources for the 4-step RACH of the second type of terminals, e.g., even RO resources, and the second subset (even RO resources) is shared to the 2-step RACH of the first type of terminals.

[0060] In another example embodiment, in case one SSB corresponds to 8 RO resources, a first PRACH mask and a second PRACH mask are configured for the 2-step RACH of the first type of terminals and the 4-step RACH of the first type of terminals, respectively; the first PRACH mask is used to determine a first subset of the 8 RO resources for the 4-step RACH of the second type of terminals, e.g., even RO resources, and the first subset (even RO resources) is shared to the 4-step RACH of the first type of terminals; the second PRACH mask is used to determine a second subset of the RO resources for the 4-step RACH of the second type of terminals, e.g., odd RO resources, and the second subset (odd RO resources) is shared to the 2-step RACH of the first type of terminals.

[0061] In some embodiments, in case one SSB corresponds to multiple RO resources, a third PRACH mask and a fourth PRACH mask are configured for the 2-step RACH of the first type of terminals and the 4-step RACH of the first type of terminals respectively; the first PRACH mask is used to determine a third subset of RO resources for the 4-step RACH of the second type of terminals, and the third subset is shared to the 4-step RACH of the first type of terminals; the second PRACH mask is used to determine a fourth subset of RO resources for the 4-step RACH of the first type of terminals, and the fourth subset is shared to the 2-step RACH of the first type of terminals.

[0062] In exemplary embodiments, in case one SSB corresponds to 8 RO resources, a third PRACH mask and a fourth PRACH mask are configured for the 2-step RACH of the first type of terminals and the 4-step RACH of the first type of terminals respectively; the first PRACH mask is used to determine a third subset of RO resources, e.g. even RO resources, for the 4-step RACH of the second type of terminals, and the third subset (even RO resources) is shared to the 4-step RACH of the first type of terminals; the second PRACH mask is used to determine a fourth subset of RO resources, e.g. the first RO resource in the even RO resources, for the 4-step RACH of the first type of terminals, and the fourth subset (the first RO resource in the even RO resources) is shared to the 2-step RACH of the first type of terminals.

[0063] In some embodiments, in case one SSB corresponds to multiple RO resources, in case a PRACH mask is configured for the 4-step RACH of the first type of terminals, and no PRACH mask is configured for the 2-step RACH of the first type of terminals, the 2-step RACH of the first type of terminals uses the same RO resources as the 4-step RACH of the first type of terminals or uses all the RO resources as the 4-step RACH of the second type of terminals.

[0064] In exemplary embodiments, in case one SSB corresponds to 8 RO resources, in case a PRACH mask is configured for the 4-step RACH of the first type of terminals, e.g. used to determine that the 4-step RACH of the first type of terminals shares even RO resources, and no PRACH mask is configured for the 2-step RACH of the first type of terminals, the 2-step RACH of the first type of terminals uses the same RO resources as the 4-step RACH of the first type of terminals, e.g. even RO resources, or uses the same RO resources as the 4-step RACH of the second type of terminals.

[0065] In the case where one SSB corresponds to multiple RO resources, when the PRACH mask is configured for the 2-step RACH of the first type of terminal, the 4-step RACH of the first type of terminal uses the same RO resource as the 2-step RACH of the first type of terminal; or, uses the same RO resource as the 4-step RACH of the second type of terminal; or, the PRACH mask is not supported for the 2-step RACH of the first type of terminal, and the PRACH mask is not configured for the 4-step RACH of the first type of terminal.

[0066] In some embodiments, in the case where the 2-step RACH resource of the second type of terminal and the 4-step RACH resource of the second type of terminal are configured, the indication information is used to indicate that the network device indicates the first type of terminal to share at least part of the PRACH resource of the second type of terminal through the first signaling.

[0067] In the embodiments of the present disclosure, the first signaling can be RMSI (remaining minimum system information), RRC (radio resource control), DCI (downlink control information), MAC CE (media access control control element), OSI (other system information), and the like.

[0068] In the case where the 2-step RACH resource of the second type of terminal and the 4-step RACH resource of the second type of terminal are configured, the network device indicates the first type of terminal to share the 2-step RACH resource of the second type of terminal through the first signaling, or the network device indicates the first type of terminal to share the 4-step RACH resource of the second type of terminal through the first signaling, or the network device indicates the first type of terminal to share the 2-step RACH resource of the second type of terminal and the 4-step RACH resource of the second type of terminal through the first signaling.

[0069] In some embodiments, the network device indicates, by the first signaling, that the first type of terminal shares at least part of PRACH resources of the second type of terminal, including: configuring one same first indication parameter for the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal; or configuring one independent second indication parameter for the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal respectively.

In some embodiments, in the case of simultaneously configuring the 4-step RACH resource of the first type of terminal, the 2-step RACH resource of the second type of terminal, and the 4-step RACH resource of the second type of terminal, the protocol stipulates or the network side configures or any other way determines that the 2-step RACH of the first type of terminal shares the RO resource of the 4-step RACH of the first type of terminal; or the protocol stipulates or the network side configures or any other way determines that the 2-step RACH of the first type of terminal shares the RO resource of the 2-step RACH of the second type of terminal; or the protocol stipulates or the network side configures or any other way determines that the 2-step RACH of the first type of terminal shares the RO resource of the 4-step RACH of the second type of terminal.

[0182] In some embodiments, in the case where the 4-step RACH of the first type of terminal shares multiple RO resource configurations, the receiving network device commonly configures one PRACH mask for the multiple RO resources; or the receiving network device configures one PRACH mask for each RO resource configuration.

[0183] In some embodiments, in the case where the receiving network device commonly configures one PRACH mask for the multiple RO resources, if in the first RO resource configuration, multiple SSBs correspond to one RO resource, the PRACH mask is invalid for the first RO resource; or the PRACH mask is invalid for all RO resources; or the PRACH mask commonly configured by the receiving network device for the multiple RO resources is not used.

[0184] In some embodiments, in the case where one SSB corresponds to multiple RO resources, the RO resources configured by different random access resources are jointly encoded, and one or more RO resources indicated by the receiving network device through codepoint or bitmap are shared RO resources for the 2-step RACH of the first type of terminal and the 4-step RACH of the first type of terminal.

In this way, the original RO configuration using the indication field under different RACH modes can be cancelled.

[0186] In some embodiments, the random access resource configuration includes: only configuring the 4-step RACH resource of the second type of terminal; or, configuring the 2-step RACH resource of the second type of terminal and the 4-step RACH resource of the second type of terminal; or, configuring the 4-step RACH resource of the second type of terminal and the 2-step RACH resource of the first type of terminal; or, configuring the 2-step RACH resource of the second type of terminal, the 4-step RACH resource of the second type of terminal, and the 2-step RACH resource of the first type of terminal; or, configuring the 4-step RACH resource of the first type of terminal and the 4-step RACH resource of the second type of terminal; or, configuring the 4-step RACH resource of the first type of terminal, the 2-step RACH resource of the second type of terminal, and the 4-step RACH resource of the second type of terminal.

[0188] The 2-step RACH of the first type of terminal can share the resources under the three configurations, so it can be indicated in the form of bitmap, such as using 8 bits to indicate: “11001000”, wherein the first two bits “11” represent that the 2-step RACH of the first type of terminal can share all the RO of the 4-step RACH of the first type of terminal, the next four bits “0010” represent 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, and the last two bits “00” represent that the 2-step RACH of the first type of terminal does not share the RO resource of the 2-step RACH of the second type of terminal.

[0189] Similarly, it can also be indicated in the form of codepoint.

[0190] In some embodiments, in the case that one 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, the protocol stipulates or the network side configures or any other way determines to configure different PRACH mask values for different features of the first type of terminal and / or the second type of terminal.

[0192] In some embodiments, in the case that one SSB corresponds to multiple RO resources, a fifth PRACH mask corresponding to sharing two RO indexes is configured.
