Abstract
Description
Technical Field
[0001] The present invention belongs to the field of communications, and in particular relates to a terminal resource parsing and identification method, a base station, an electronic device and a storage medium. Background Art
[0002] Currently, 3GPP (3rd Generation Partnership Project) is discussing how the network can identify whether a UE is a RedCap UE or an eMBB UE when the RedCap UE (mid-range capability air interface user equipment) and the eMBB UE (Enhanced Mobile Broadband) access the same cell. Figure 1 A 4-step random access process is shown. Considering the possibility of introducing a coverage enhancement solution for RAR and Msg4 for RedCap UE. Taking FR1 (450MHz-6000MHz, also known as Sub-6GHz) as an example, the bandwidth supported by eMBB UE can reach 100MHz, while for RedCap UE, the maximum bandwidth is limited to 20MHz in the initial access process. Msg3 / Msg5 is scheduled on the initial uplink BWP. Since the initial uplink BWP (bandwidth part) bandwidths of RedCap UE and eMBB UE can be different, the network needs to determine which initial uplink BWP to use when RAR schedules the uplink frequency domain resources used by Msg3 for the UE. Therefore, it is necessary to study how the network can identify whether a UE is a RedCap UE or an eMBB UE during the random access phase.
[0003] Currently, there are three main solutions for identifying whether a UE is a RedCap UE or an eMBB UE:
[0004] Solution 1: Use a separate initial UL BWP, a separate PRACH resource, or a separate PRACH preamble partitioning when transmitting Msg1;
[0005] Solution 2: Report via Msg5 or UE capability;
[0006] Scenario 3: During MsgA transmission.
[0007] In solution 1, RedCap UE needs to use a separate UL BWP or a separate PRACH (Physical Random Access Channel) resource, or use a PRACH preamble (random access preamble) different from that of eMBB UE. When deploying a network, it is hoped that RedCap UE and eMBB UE can share PRACH resources and PRACH Preamble. Then, Solution 1 will not be selected. Solution 2 will limit the Msg3 / 5 scheduling within the uplink bandwidth of the RedCap UE, and neither the coverage enhancement of RAR (Random Access Response) nor msg4 is available. Solution 3 is only applicable to 2-step RACH and not applicable to traditional 4-step RACH.
[0008] If the operator hopes that the RedCap UE and the eMBB UE share the PRACH resources and PRACH preamble during network deployment. When the network schedules the uplink frequency domain resources used by Msg3 in msg2, if the UL BWPs of the RedCap UE and the eMBB UE are different, since the network does not know whether the UE is a RedCap UE or an eMBB UE, it is impossible to determine which UL BWP should be used for scheduling. Summary of the Invention
[0009] The technical problem to be solved by the present invention is the defect that the network cannot determine whether the UE is a RedCap UE or an eMBB UE, and thus cannot determine which UL BWP should be used for scheduling, and provides a method for terminal resource parsing and identification, a base station, an electronic device, and a storage medium.

[0052] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.
[0053] First, a brief description is given of the frequency domain resource transmission used by Msg3 and the interpretation of the scheduling information of the frequency domain resources by the eMBB UE:
[0054] For the frequency domain resources used by Msg3, the initial transmission uses the UL grant scheduling in RAR (msg2), and the retransmission uses DCI0-0 scheduling. Both use type 1, i.e., RIV (Resource indicator value) resource allocation method:

[0061] The network schedules the frequency domain resources used by Msg3 according to the initial UL BWP of the eMBB UE. The eMBB UE interprets the scheduling information of the frequency domain resources according to the requirements of the current 3GPP protocol and obtains the RB start RedCap UE interprets the RB of eMBB UE according to the requirements of the current 3GPP protocol. start and length, and then map the frequency domain resource scheduling to the initial UL BWP of the RedCap UE. The mapping methods can be as follows. For the convenience of description, the starting RB of the initial UL BWP of the RedCap UE is the N0th RB of the initial UL BWP of the eMBB UE, and the last RB is the Nth RB of the initial UL BWP of the eMBB UE. L RBs, the total number of RBs included in the RedCap UE initial UL BWP is N T . (RB start mod N T )=Ms;(RB start +length-1)mod N T =Me(when RB start +length-1mod N T =0, Me=N T ).
[0062] Example 1
[0063] This embodiment provides a method for a terminal to perform resource scheduling analysis on a frequency domain resource corresponding to Msg3. The method includes:
[0064] The first type of terminal performs frequency domain resource allocation according to the initial uplink BWP of the second type of terminal broadcasted by SIB (system message block), parses the corresponding actual scheduled physical RB, and maps the scheduled resources to the actual scheduled physical RB-offset (resource block-offset).
[0065] In this embodiment, RedCap UE is used as the first type of terminal and eMBB UE is used as the second type of terminal for description. Of course, the present invention is not limited to this. As long as the first type of terminal and the second type of terminal share The first type of terminal is initially The maximum bandwidth of the initial access process is less than the second type of terminal The maximum bandwidth of the initial access process is applicable to all the above methods.
[0066] The limitation of the method in this embodiment is that Msg3 can only be scheduled on the resources corresponding to the initial uplink BWP of the RedCap UE plus the offset. The resource parts of the RedCap UE and the eMBB UE overlap. If there are both a RedCap UE and an eMBB UE using the same preamble and RO simultaneously, the interference is large, and the base station reception complexity may be relatively high.
[0067] The following is an example: offset = 1, the eMBB UE occupies 100M bandwidth, SCS = 30kHz, and there are 273 PRBs. The RedCap UE occupies 20M bandwidth, SCS = 30kHz, and there are 51 PRBs. The 20M bandwidth of the RedCap UE is within the 100M bandwidth of the eMBB UE. Starting from the 5th PRB, that is, the first PRB of the 20M bandwidth of the RedCap UE is actually the 5th PRB of the eMBB UE. The resources scheduled for the eMBB are 7 - 10 PRBs. Then, with offset = 1, the PRBs of the RedCap UE are the 6th - 9th PRBs in the 100M and the 2nd - 5th PRBs in the 20M of the RedCap.
[0068] Embodiment 2
[0069] This embodiment provides a method for a terminal to resolve the frequency - domain resources corresponding to the resource scheduling of Msg3. The method includes:
[0070] The first type of terminal resolves the resource allocation as:
[0071] If Ms > Me, the starting RB of the first type of terminal is the (N T - length + 1) - th RB of the initial uplink BWP of the first type of terminal, and the length is length;
[0072] If Ms < Me, the starting RB of the first type of terminal is the (Ms + offset) - th RB of the initial uplink BWP of the first type of terminal, and the length is length; where when RB start >= N0 and RB start + length - 1 <= N L the offset takes a positive integer value, otherwise offset = 0; the constraint condition is that Me + offset is less than or equal to N L .
[0073] In this embodiment, the RedCap UE is used as the first type of terminal, and the eMBB UE is used as the second type of terminal for illustration. Of course, the present invention is not limited thereto. As long as the first type of terminal and the second type of terminal share the RO and the maximum bandwidth of the first type of terminal in the initial access process is less than the maximum bandwidth of the second type of terminal in the initial access process, the method is applicable.
[0074] The following is an example: The eMBB UE occupies 100M bandwidth, SCS = 30kHz, and there are 273 PRB. RedCap UE Occupies 20M bandwidth, SCS = 30kHz, has 51 PRBs, that is, N T =51. Assume that the eMBB scheduling is RB start = 48, length = 5, then Ms = RB start mod N T = 48; Me = (RB start + length - 1) mod N T = 1. The RedCap UE is parsed to start from the 47th RB of the 20M of RedCap, with a length of 5, that is, the 47th - 51st RBs.
[0075] The method of this embodiment simply defines the parsing method of the RedCap UE for resource scheduling according to the relationship between Ms and Me. Because it is simple, there will be a situation where the resources of the eMBB and the RedCap UE partially overlap. For the possible overlapping situations, according to the relationship between the resources scheduled by the eMBB UE and the initial UL BWP of the RedCap UE, they are divided into the following several types:
[0076] 1. When RB start + length - 1 < N0 or RB start > N L : The resources corresponding to the eMBB UE are not within the initial uplink BWP of the RedCap UE, and there will be no resource overlap no matter how they are mapped.
[0077] 2. When RB start < N0, and RB start + length - 1 > N0, if Ms + N0 - 1 > RB start + length - 1, there will be no overlap between the resources corresponding to the eMBB UE and the RedCap UE resources, otherwise there will be partial overlap.
[0078] 3. When RB start >= N0 and RB start + length - 1 <= N L , if offset > length, the resources corresponding to the eMBB UE and the RedCap UE resources do not overlap, otherwise there will be partial overlap.
[0079] 4. When RB start = <N L and RB start + length - 1 > N L at this time, according to the method of this embodiment, the resources corresponding to the eMBB UE and the RedCap UE resources will partially overlap.
[0080] Reference can be made to Figure 2 the overlapping situation of the resources corresponding to the eMBB UE and the RedCap UE resources in the above four cases shown. Among them, in the first case, if the resources parsed by the eMBB UE are not within the 20M of the RedCap, there will be no overlap between the eMBB and the RedCap UE resources. The overlaps in the second to fourth cases are shown in the figure.
[0081] Embodiment 3
[0082] This embodiment provides a method for a terminal to schedule and parse the frequency-domain resources corresponding to Msg3. The method includes:
[0083] The first type of terminal parses the resource allocation as:
[0084] When RB start < N0 and RB start + length - 1 > N0, the starting RB of the first type of terminal is Me, and the length is length, that is, the actual physical RB is before the first RB occupied by the second type of terminal;
[0085] When RB start = <N L and RB start + length - 1 > N L at this time, the starting RB of the first type of terminal is the (RB start + length - N0 + 1)-th RB of the initial uplink BWP of the first type of terminal, and the length is length, that is, the actual physical RB starts from the end of the second type of terminal.
[0086] In this embodiment, the RedCap UE is used as the first type of terminal and the eMBB UE is used as the second type of terminal for illustration. Of course, the present invention is not limited thereto. As long as the first type of terminal and the second type of terminal share the RO and the maximum bandwidth of the first type of terminal in the initial access process is less than the maximum bandwidth of the second type of terminal in the initial access process, the method is applicable.
[0087] The method of this embodiment enables the resources corresponding to the eMBB UE and the RedCap UE resources not to overlap.

[0094] The parsing module 101 is used to perform frequency - domain resource allocation according to the initial uplink BWP of the second - type terminal broadcast by SIB, parse out the corresponding actually scheduled physical RBs, and map the scheduled resources to the actually scheduled physical RB - offset.
[0095] Or, the parsing module 101 is used to parse the resource allocation as:

[0097] If Ms<Me, the starting RB of the terminal is the (Ms + offset) - th RB of the terminal's initial uplink BWP, and the length is length; where when RB start >=N0 and RB start + length - 1<=N L the offset takes a positive integer value, otherwise offset = 0; the constraint condition is that Me+offset is less than or equal to N L .
