Description

Technical Field

[0001] The present invention belongs to the field of communications, and in particular relates to a method, a base station, a device and a medium for determining an initial uplink BWP of a terminal. Background Art

[0002] Currently, 3GPP (3rd Generation Partnership Project) is discussing the coexistence of RedCap (mid-range capability air interface) UE (User Equipment) and eMBB (Enhanced Mobile Broadband) UE. Taking FR1 (450MHz-6000MHz, also known as Sub-6GHz) as an example, the bandwidth supported by eMBB UE can reach 100MHz, while the maximum bandwidth of RedCap UE is limited to 20MHz during the initial access process. According to the current 3GPP protocol, gNB (5G base station) will configure the initial uplink BWP (bandwidth part) of eMBB UE in SIB (System Information Block) and the frequency domain position of RO (RACHOccasion, random access time-frequency resources) to be used by eMBB UE during the initial access process.

[0003] According to the current 3GPP protocol, the initial downlink (initial DL) BWP of the UE is determined by the configured CORESET0. The maximum bandwidth of the RedCap UE during the initial access process is 20MHz (FR1), which is compatible with all CORESET0 (control resource sets) of the eMBB UE. The initial uplink BWP of the eMBB UE is configured through SIB1. According to the configuration of PRACH (Physical Random Access Channel) by SIB1 and 38.211vg00 Table 6.3.3.2-1, the frequency domain resources occupied by each RO can be determined.

[0004] For TDD (time division duplex), since the initial downlink and uplink BWP center frequencies are the same, once the bandwidths of the initial downlink BWP and the initial uplink BWP are determined, the starting position of the initial uplink BWP is already determined. However, for FDD (frequency division duplex), there is no constraint that the uplink and downlink center frequencies are the same. According to the current 3GPP protocol, the bandwidth supported by eMBB UE can reach 100MHz, and the initial uplink BWP of eMBB UE can be configured to be greater than 20MHz, resulting in RedCap UE being unable to fully reuse the initial uplink BWP configuration of eMBB UE. It is necessary to study the method of determining the initial uplink BWP of RedCap UE.

[0005] In addition, one possible configuration of the network is that RedCap UE and eMBB UE share RO, and the last PRB occupied by the RO of the eMBB UE is more than 20MHz away from the initial uplink BWP starting PRB of the eMBB UE. According to the configuration of SIB1, the multiplexing factor msg1-FDM of the eMBBUE RO can be 8 (that is, there are 8 ROs in the frequency domain), such as Figure 1 As shown in the figure. For some preamble (random access preamble) formats that can be used by eMBB UE (as listed in the table below), when msg1-FDM=8, the bandwidth occupied by all ROs will exceed 20MHz, which exceeds the maximum bandwidth of the initial access phase of RedCap UE. It is necessary to study how to use msg1-FDM=8 for these preamble formats in the scenario where RedCap UE and eMBB UE share RO.

[0006]

[0007] Currently, for NR-U (NR in Unlicensed Spectrum, i.e. NR working in unlicensed spectrum), the uplink BWP can be determined based on the PRACH resources used by the UE. However, this requires that the UE in NR-U knows the upper and lower boundaries of the uplink BWP and the configuration of different RB sets (Resource Blocks), and the UE determines which RBset to use based on the PRACH resources used. This is not applicable when the boundaries of the uplink BWP are unknown. Summary of the invention

[0008] The technical problem to be solved by the present invention is how to determine the initial uplink BWP of a RedCap UE, especially to determine the initial uplink BWP of a RedCap UE when the boundary of the initial uplink BWP is unknown, and a method, base station, device and medium for determining the initial uplink BWP of a terminal are provided.

[0107] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0108] Example 1

[0109] Figure 1 A method for determining an initial uplink BWP of a terminal according to this embodiment is shown, which includes:

[0110] Step 101: The gNB (5G base station) broadcasts the initial uplink BWP position of the first type of terminal through SI (System Information).

[0111] The above steps are implemented in one of the following three optional ways:

[0112] Option 1a: The first type of terminal and the second type of terminal share the RO during the initial access process, and the maximum bandwidth of the first type of terminal during the initial access process is less than the maximum bandwidth of the second type of terminal during the initial access process. The SI includes information for implementing the following configurations:

[0113] Configure the offset of the initial uplink BWP of the first type of terminal compared to the first PRB occupied by PRACH.

[0114] Option 1b: The first type of terminal and the second type of terminal share the RO during the initial access process, and the maximum bandwidth of the first type of terminal during the initial access process is less than the maximum bandwidth of the second type of terminal during the initial access process. The SI includes information for implementing the following configurations:

[0115] Configure an offset of a first PRB of an initial uplink BWP of the first category of terminals compared to an initial uplink BWP of the second category of terminals.

[0116] In this embodiment, the first type of terminals include but are not limited to RedCap UE; the second type of terminals include but are not limited to eMBB UE. Figure 3 A schematic diagram of configuring the initial uplink BWP of the RedCap UE according to the eMBB UE is shown, which shows the position of the offset in 1a and 1b.

[0117] In 1a and 1b, the following two scenarios can be divided according to the relationship between the bandwidth occupied by all ROs configured by the network and the initial uplink BWP bandwidth of the first type of terminal:

[0118] Scenario 1: The bandwidth occupied by all ROs configured by the network is less than or equal to the initial uplink BWP bandwidth of the first type of terminals, where the initial uplink BWP bandwidth of the first type of terminals can be configured through SIB. At this time, the offsets of different SSB broadcasts configured in 1a and 1b can be the same.

[0119] Scenario 2: The bandwidth occupied by all ROs configured by the network is greater than the initial uplink BWP bandwidth of the first category of terminals, where the initial uplink BWP bandwidth of the first category of terminals can be configured through SIB.

[0120] At this time, the offsets of different SSB broadcasts configured by 1a and 1b may be different. For 1a, when the total PRACH resources are greater than the initial uplink BWP bandwidth of the first type of terminal, the offset may be positive or negative. For 1b, when the total PRACH resources are greater than the initial uplink BWP bandwidth of the first type of terminal (taking RedCap UE as an example, 20M), the offset is always positive.

[0121] Alternatively, the offsets of different SSB broadcasts configured by 1a and 1b are the same, but when the SSBs corresponding to the first type of terminals are different, offset_i is added to the offset, and offset_i is related to the number of PRBs occupied by RO and the beam corresponding to the SSB where the first type of terminals are located.

[0122] Among them, offset_i is related to the number of PRBs occupied by the RO and the beam corresponding to the SSB where the first type of terminal is located, specifically including when the first type of terminal is located in the beam corresponding to SSB_i:

[0123] When the total bandwidth occupied by multiple ROs corresponding to SSB_i exceeds the initial uplink BWP bandwidth of the first type of terminals, the first type of terminals selects M consecutive ROs as the final available ROs, where M satisfies the following conditions:

[0124] M*RBnum<the initial uplink BWP bandwidth of the first type of terminal, and (M+1)*RBnum>the initial uplink BWP bandwidth of the first type of terminal, where RBnum is the number of RBs occupied by an RO, which is determined by the configuration parameters of the RO;

[0125] The manner in which the first type of terminal selects M consecutive ROs needs to be agreed upon in advance (such as agreed upon in the 3GPP protocol) or configured by the network;

[0126] offset_i=RBnum*N, where N is the minimum index of the RO selected by the first type of terminals - 1.

[0127] offset_i is related to the number of PRBs occupied by the RO and the beam corresponding to the SSB where the first type of terminal is located, and specifically includes when the first type of terminal is located in the beam corresponding to SSB_i:

[0128] When the total bandwidth occupied by all ROs corresponding to SSB_i is less than the initial uplink BWP bandwidth of the first type of terminals, offset_i=RBnum*Q, where Q satisfies:

[0129] RO Q+1 to RO p Contains the RO corresponding to all SSB_i, and (PQ)*RBnum is less than or equal to the initial uplink BWP bandwidth of the first type of terminal;

[0130] Wherein, P represents the maximum RO corresponding to SSB_i. The manner in which the first type of terminal determines Q needs to be agreed upon in advance (such as agreed upon in the 3GPP protocol) or configured by the network.

[0131] like Figure 4For the four tables shown, when the RedCap UE is located in the beam corresponding to SSB_i, according to the current 3GPP protocol's allocation principle for RO frequency-domain resources, from the frequency-domain perspective, SSB_i corresponds to one or more ROs (Tables 1 and 2 correspond to multiple ROs, and Tables 3 and 4 correspond to one RO). When the total bandwidth occupied by the multiple ROs corresponding to SSB_i exceeds the initial uplink BWP bandwidth of the RedCap UE, as in Table 1, when the RedCap UE is in the beam corresponding to SSB_1, RO1 - 8 can all be used, and the bandwidth occupied by these 8 ROs is greater than the initial uplink BWP bandwidth of the RedCap UE. At this time, the UE selects continuous M ROs as the finally available ROs, where M * RBnum < the initial uplink BWP bandwidth of the RedCap UE and (M + 1) * RBnum > the initial uplink BWP bandwidth of the RedCap UE. For Table 1, M < 8, and for Table 2, M <= 4. If the UE selects RO5 - 8 as the finally available ROs, then N = 4. When the total bandwidth occupied by all the ROs corresponding to SSB_i is less than the initial uplink BWP bandwidth of the RedCap UE, taking Table 3 as an example, offset_1 = 0; SSB4 corresponds to the 4th RO, and offset_4 corresponding to SSB4 = RBnum * Q, where Q <= 3, so that from RO Q+1 to RO p can include all the ROs corresponding to SSB_i. Taking Table 2 as an example again, offset_1 / 2 / 3 / 4 = 0; offset_5 / 6 / 7 / 8 = RBnum * Q, where Q <= 4, so that the 5th RO can fall within the initial uplink BWP bandwidth of the RedCap UE.

[0132] Selection 1c: The SI includes information for implementing the following configuration:

[0133] Configure the absoluteFrequencyPointA (indicating the position of PointA in the frequency domain, represented by ARFCN (Absolute Radio Frequency Channel Number)), offsetToCarrier (used to represent the frequency offset between PointA and the lowest subcarrier in the lowest RB that overlaps with the SS / PBCH block (SSB is used for the UE to perform initial cell selection), where the SCS of the Resource Block here is specified by the signaling subCarrierSpacingCommon), and locationAndBandwidth (indicating the starting position of the PRB of the BWP and the number of occupied PRBs in the form of RIV) of the initial uplink BWP of the first type of terminal.

[0134] In the first two methods of this embodiment, when configuring the initial uplink BWP position of the first type of terminal, the initial uplink BWP and PRACH resources of the second type of terminal are used as references, and fewer bits can be used to indicate the initial uplink BWP position of the first type of terminal. In particular, the value range of the first method is smaller than that of the second method, which saves more bits.

[0135] Example 2

[0136] This embodiment provides a method for determining an initial uplink BWP of a terminal, wherein a first type of terminal and a second type of terminal share an RO during an initial access process and a maximum bandwidth of the first type of terminal during the initial access process is less than a maximum bandwidth of the second type of terminal during the initial access process. The method includes:

[0137] The initial uplink BWP position of the first category of terminals is determined in an agreed manner according to the frequency domain resources occupied by the PRACH.

[0138] In this embodiment, the following two scenarios can be divided according to the relationship between the bandwidth occupied by all ROs configured by the network and the initial uplink BWP bandwidth of the first type of terminals:

[0139] Scenario 1: The bandwidth occupied by all ROs configured by the network is less than or equal to the initial uplink BWP bandwidth of the first type of terminal, where the initial uplink BWP bandwidth of the first type of terminal can be configured through SIB. At this time, taking the resources occupied by all ROs as the benchmark, the content agreed in this method may include any one of the following three types:

[0140] Option 2a-1: the initial uplink BWP of the first category of terminals takes the central RB occupied by the PRACH as the central RB. If the initial uplink BWP of the first category of terminals calculated in this way exceeds the initial uplink BWP boundary of the second category of terminals, the initial uplink BWP of the first category of terminals takes the last PRB of the initial uplink BWP of the second category of terminals as the last PRB or takes the first PRB of the initial uplink BWP of the second category of terminals as the first PRB;

[0141] Option 2b-1: the initial uplink BWP of the first category of terminals takes the last PRB occupied by the PRACH as the last PRB. If the initial uplink BWP of the first category of terminals calculated in this way exceeds the initial uplink BWP boundary of the second category of terminals, the initial uplink BWP of the first category of terminals takes the first PRB of the initial uplink BWP of the second category of terminals as the first PRB.

[0142] Option 2c-1: The initial uplink BWP of the first category terminal takes the first PRB occupied by PRACH as the first PRB. If the initial uplink BWP of the first category terminal calculated in this way exceeds the initial uplink BWP boundary of the second category terminal, the initial uplink BWP of the first category terminal takes the last PRB of the initial uplink BWP of the second category terminal as the last PRB.

[0143] Scenario 2: The bandwidth occupied by all ROs configured by the network is greater than the initial uplink BWP of the first type of terminal, where the initial uplink BWP bandwidth of the first type of terminal can be configured through SIB. At this time, one or more ROs corresponding to the SSB are selected as the reference (refer to Example 1 Figure 4 Table 3 and Table 4: Table 3, for SSB_4, is based on the 4th RO; Table 4, for SSB_7, is based on the 7th RO), the agreed contents may include:

[0144] When the first type of terminal is located in the beam corresponding to SSB_i, when the total bandwidth occupied by multiple ROs corresponding to SSB_i exceeds the initial uplink BWP bandwidth of the first type of terminal, the first type of terminal selects M consecutive ROs as the final available ROs, where M satisfies the following conditions:

[0145] M*RBnum<the initial uplink BWP bandwidth of the first type of terminal, and (M+1)*RBnum>the initial uplink BWP bandwidth of the first type of terminal, where RBnum is the number of RBs occupied by one RO, which is determined by the configuration parameters of the RO, and the manner in which the first type of terminal selects M consecutive ROs needs to be agreed in advance (such as agreed in the 3GPP protocol) or network configured; and any one of the following three:

[0146] Option 2a-2: the initial uplink BWP of the first category of terminals takes the central RB occupied by the selected RO as the central RB. If the initial uplink BWP of the first category of terminals calculated in this way exceeds the initial uplink BWP boundary of the second category of terminals, the initial uplink BWP of the first category of terminals takes the last PRB of the initial uplink BWP of the second category of terminals as the last PRB or takes the first PRB of the initial uplink BWP of the second category of terminals as the first PRB;

[0147] Option 2b-2: the initial uplink BWP of the first category of terminals takes the last PRB occupied by the selected RO as the last PRB. If the initial uplink BWP of the first category of terminals calculated in this way exceeds the initial uplink BWP boundary of the second category of terminals, the initial uplink BWP of the first category of terminals takes the first PRB of the initial uplink BWP of the second category of terminals as the first PRB.

[0148] Option 2c-2: The initial uplink BWP of the first category terminal takes the first PRB occupied by the selected RO as the first PRB. If the initial uplink BWP of the first category terminal calculated in this way exceeds the initial uplink BWP boundary of the second category terminal, the initial uplink BWP of the first category terminal takes the last PRB of the initial uplink BWP of the second category terminal as the last PRB.

[0149] In scenario 2, the agreed content may also include:

[0150] When the first type of terminal is located in the beam corresponding to SSB_i, and when the total bandwidth occupied by all ROs corresponding to SSB_i does not exceed the initial uplink BWP bandwidth of the first type of terminal, any one of the following three is agreed upon:

[0151] Option 2a-3: The initial uplink BWP of the first type of terminal takes the central RB occupied by all ROs corresponding to SSB_i as the central RB. If the initial uplink BWP of the first type of terminal calculated in this way exceeds the initial uplink BWP boundary of the second type of terminal, the initial uplink BWP of the first type of terminal takes the last PRB of the initial uplink BWP of the second type of terminal as the last PRB or takes the first PRB of the initial uplink BWP of the second type of terminal as the first PRB;

[0152] Option 2b-3: the initial uplink BWP of the first category of terminals takes the last PRB occupied by all ROs corresponding to SSB_i as the last PRB. If the initial uplink BWP of the first category of terminals calculated in this way exceeds the initial uplink BWP boundary of the second category of terminals, the initial uplink BWP of the first category of terminals takes the first PRB of the initial uplink BWP of the second category of terminals as the first PRB;

[0153] Option 2c-3: The initial uplink BWP of the first category terminal takes the first PRB occupied by all ROs corresponding to SSB_i as the first PRB. If the initial uplink BWP of the first category terminal calculated in this way exceeds the initial uplink BWP boundary of the second category terminal, the initial uplink BWP of the first category terminal takes the last PRB of the initial uplink BWP of the second category terminal as the last PRB.

[0154] In this embodiment, the first type of terminals include but are not limited to RedCap UE; the second type of terminals include but are not limited to eMBB UE.

[0155] Example 3

[0156] Figure 5A base station of this embodiment is shown, which includes a sending module 201. The sending module 201 is used to broadcast the initial uplink BWP position of the first type of terminal through SI.

[0157] The sending module 201 is implemented in the following three ways:

[0158] Option 1a: The first type of terminal and the second type of terminal share the RO during the initial access process, and the maximum bandwidth of the first type of terminal during the initial access process is less than the maximum bandwidth of the second type of terminal during the initial access process. The SI includes information for implementing the following configurations:

[0159] Configure the offset of the initial uplink BWP of the first type of terminal compared to the first PRB occupied by PRACH.

[0160] Option 1b: The first type of terminal and the second type of terminal share the RO during the initial access process, and the maximum bandwidth of the first type of terminal during the initial access process is less than the maximum bandwidth of the second type of terminal during the initial access process. The SI includes information for implementing the following configurations:

[0161] Configure an offset of a first PRB of an initial uplink BWP of the first category of terminals compared to an initial uplink BWP of the second category of terminals.

[0162] In the first two methods, the following two scenarios can be divided according to the relationship between the bandwidth occupied by all ROs configured by the network and the initial uplink BWP bandwidth of the first type of terminal:

[0163] Scenario 1: The bandwidth occupied by all ROs configured by the network is less than or equal to the initial uplink BWP bandwidth of the first type of terminal, where the initial uplink BWP bandwidth of the first type of terminal can be configured through SIB. At this time, the offsets of different SSB broadcasts configured in the first two ways can be the same.

[0164] Scenario 2: The bandwidth occupied by all ROs configured by the network is greater than the initial uplink BWP bandwidth of the first category of terminals, where the initial uplink BWP bandwidth of the first category of terminals can be configured through SIB.

[0165] At this time, the offsets of different SSB broadcasts configured in the first two methods may be different.

[0166] Alternatively, the offsets of different SSB broadcasts configured in the first two methods are the same, but when the SSBs corresponding to the first type of terminals are different, offset_i is added to the offset, and offset_i is related to the number of PRBs occupied by the RO and the beam corresponding to the SSB where the first type of terminals are located.

[0167] offset_i is related to the number of PRBs occupied by the RO and the beam corresponding to the SSB where the first type of terminal is located, specifically including: when the first type of terminal is located in the beam corresponding to SSB_i, when the total bandwidth occupied by multiple ROs corresponding to SSB_i exceeds the initial uplink BWP bandwidth of the first type of terminal, the first type of terminal selects M consecutive ROs as the final available ROs, where M satisfies the following conditions:

[0168] M*RBnum<the initial uplink BWP bandwidth of the first type of terminal, and (M+1)*RBnum>the initial uplink BWP bandwidth of the first type of terminal, where RBnum is the number of RBs occupied by an RO, which is determined by the configuration parameters of the RO;

[0169] The manner in which the first type of terminal selects M consecutive ROs needs to be agreed upon in advance (such as agreed upon in the 3GPP protocol) or configured by the network;

[0170] offset_i=RBnum*N, where N is the minimum index of the RO selected by the first type of terminals - 1.

[0171] offset_i is related to the number of PRBs occupied by the RO and the beam corresponding to the SSB where the first type of terminal is located, specifically including: when the first type of terminal is located in the beam corresponding to SSB_i, when the total bandwidth occupied by all ROs corresponding to SSB_i is less than the initial uplink BWP bandwidth of the first type of terminal, offset_i=RBnum*Q, Q satisfies:

[0172] RO Q+1 to RO p Contains the RO corresponding to all SSB_i, and (PQ)*RBnum is less than or equal to the initial uplink BWP bandwidth of the first type of terminal;

[0173] Wherein, P represents the maximum RO corresponding to SSB_i. The manner in which the first type of terminal determines Q needs to be agreed upon in advance (such as agreed upon in the 3GPP protocol) or configured by the network.

[0174] Option 1c: The SI includes information to implement the following configurations:

[0175] Configure the absoluteFrequencyPointA, offsetToCarrier and locationAndBandwidth of the initial uplink BWP of the first type of terminals.

[0176] In this embodiment, the first type of terminals include but are not limited to RedCap UE; the second type of terminals include but are not limited to eMBB UE.

[0177] In the first two methods of this embodiment, when configuring the initial uplink BWP position of the first category terminal, the initial uplink BWP and PRACH resources of the second category terminal are used as references, and fewer bits can be used to indicate the initial uplink BWP position of the first category terminal.

[0184] Option 2c-1: The initial uplink BWP of the first category terminal takes the first PRB occupied by PRACH as the first PRB. If the initial uplink BWP of the first category terminal calculated in this way exceeds the initial uplink BWP boundary of the second category terminal, the initial uplink BWP of the first category terminal takes the last PRB of the initial uplink BWP of the second category terminal as the last PRB.

[0189] Option 2b-2: the initial uplink BWP of the first category of terminals takes the last PRB occupied by the selected RO as the last PRB.
