[0052] Before introducing in detail the resource configuration method provided by an embodiment of the present disclosure, the communication technology used in the embodiment of the present disclosure is presented.

[0053] (1) New radio access to unlicensed spectrum (NR-U) system:

[0054] Unlicensed spectrum is spectrum allocated by countries and regions that can be used for radio communications. This spectrum is generally considered to be shared, meaning that communications devices in different communications systems can use this spectrum without having to request an exclusive license from the government to use the spectrum, as long as they meet the regulatory requirements set by the country or region. To ensure that various communications systems using unlicensed spectrum for wireless communications can coexist peacefully in that spectrum, some countries or regions have established regulatory requirements that must be met when using unlicensed spectrum. For example, in some areas, communication devices follow a listen-before-transmit (LBT) principle, that is, communication devices are required to perform channel listening before transmitting signals over unlicensed spectrum channels. A communication device can transmit signals only when the result of channel detection is that the channel is free; If the result of a communication device detecting an unlicensed spectrum channel is that the channel is busy, then the communication device cannot transmit signals. To ensure fairness in a single transmission, the duration of a signal transmission by a communications device using an unlicensed spectrum channel cannot exceed the Maximum Channel Occupancy Time (MCOT).

[0055] (2) Guard band (GB) on the carrier in the NR-U system:

[0056] The concept of a resource block (RB) is introduced in broadband resource configurations. One set of RBs includes a group of consecutive RBs, and one set of RBs corresponds to at least one listen before talk (LBT) frequency band, and one LBT frequency band includes 20 MHz. Since the network device can configure at least two sets of RBs for a terminal, when the network device configures at least two sets of RBs for a terminal, a carrier guard band is included between two adjacent RB sets, and the carrier guard band includes an integer R.B.

[0057] In one case, the size of the guard band in the carrier is obtained in accordance with the protocol. As an example, Table 1 shows the default configuration of RB sets and guard bands between two RB sets at a particular subcarrier spacing and carrier bandwidth.

[0058] Table 1

SCS Carrier BW at 20 MHz BW carrier at 40 MHz BW carrier at 60 MHz BW carrier at 80 MHz 15 kHz 106 105-6-105 Max. 216 N/A N/A 30 kHz 51 50-6-50 Max. 106 50-6-50-6-50 Max.162 50-6-50-5-50-6-50 Max.217 Alto. 1 60 kHz 24 [23-5-23] Max. 51 [23-5-23-5-23] Max. 79 [23-5-23-5-23-5-23] Max.107 Alto. 2 60 kHz [25] [24-3-24] Max. 51 [24-3-25-3-24] Max. 79 [24-4-24-3-24-4-24] Max.107

[0059] In another case, the guard band on the carrier is obtained according to the configuration information of the network device. For example, if the terminal is configured as a network device with N-1 sets of guard band indications: { , }, …, { , }, where the guard band is specified according to the common carrier resource block (CRB) index, then the terminal can determine that the number of RB sets included in the cell is N, where the guard band is determined according to the CRB grid, and the available PRBs in the RB set include:

[0060] RB Set 1: [ , -1]

[0061] RB Set 2: [ +1, -1]

[0062] ...

[0063] Set N RB: [ +1, ]

[0064] At the same time And respectively represent the indices of the starting RB and ending RB of the cell, or And respectively representing the starting RB and ending RB indices of the BWP cell.

[0065] Next, in the following embodiments of the present disclosure, the carrier guard band is described using the uplink BWP of the terminal as an example.

[0066] The uplink BWP may include an integer number of RB sets. Please refer to Figure 1B. FIG. 1B is a schematic diagram of an uplink BWP including two sets of RBs, and a starting position of the uplink BWP is configured based on the CRB index. In this case, a guard band in the carrier is included between two sets of RBs. The guard band can be determined according to the guard band configuration parameters of the network device { , } or may be defined according to the protocol. If the terminal device guard band is configured by the network device, the starting position and ending position of the guard band are based on the CRB index.

[0067] In addition, in the NR-U system, resource allocation based on an interleaved structure is introduced for uplink transmission. For a subcarrier spacing of 15 kHz, it includes 10 interlaces (ie, M=10), and the interlace index is from 0 to 9; for a subcarrier spacing of 30 kHz, it includes 5 interlaces (i.e. M=5), and the interlace index is from 0 to 4. The definition of interleave structure is as follows: Interlace 0 is defined according to the CRB grid, starting from CRB 0, and among the RBs in each interlace, the frequency domain interval between two adjacent RBs is M RB.

[0068] (3) RACH random access process and PRACH resource configuration:

[0069] In the NR system or NR-U system, the RACH random access process includes two cases: a four-stage process and a two-stage process. Among them, the delay of the four-step RACH process is relatively large. Compared with the four-stage RACH process, the two-stage RACH process can reduce the access delay.

[0070] For a four-step process:

[0071] In the first step, the terminal sends a random access preamble sequence (message 1, Msg1) to the network device on the PRACH channel. The PRACH resource used for PRACH transmission may also be referred to as the RO resource (RACH event).

[0072] In the second step, after detecting that the terminal is sending the access preamble sequence, the network device sends a random access response (RAR, that is, message 2, Msg2) to the terminal to inform the terminal that the uplink resource information may used to send message 3 (Msg3) and assign a temporary TC-RNTI to the terminal and provide the terminal with a TA command, etc.

[0073] In the third step, after receiving a random access response (RAR), the terminal sends a Msg3 message on the uplink resource indicated by the random access response message.

[0074] In the fourth step, the network device sends a Msg4 message to the terminal, which may include a contention resolution message.

[0075] For a two-step process:

[0076] In the first step, the terminal sends message A (MsgA) to the base station via a PRACH and a PUSCH, where Msg A includes a random access preamble sequence and msgA-PUSCH. The msgA-PUSCH resource used for msgA-PUSCH transmission may also be referred to as a PO resource (PUSCH event).

[0077] In the second step, after detecting MsgA, the network device sends a random access response, that is, message B (MsgB), to the terminal.

[0078] The terminal will determine the frequency domain location of the PRACH resource (also referred to as the RO resource (RACH Occasion)) in accordance with the initial frequency domain location configuration parameter of the PRACH resource (for example, the top layer parameter msg1-FrequencyStart or msgA-RO-FrequencyStart ) , reported by the network device. In particular, the frequency domain initial position configuration parameter is used to indicate the frequency domain offset of the first frequency domain PRACH resource in the uplink BWP (eg, the initial uplink BWP or the activated uplink BWP) relative to the first PRB (which is, PRB 0) Uplink BWP. The network device may also communicate the amount of frequency division multiplexing (FDM) PRACH resources in the same unit of time through a higher layer parameter (eg, msg1-FDM or msgA-RO-FDM ). The terminal can determine the frequency domain position of a PRACH resource included in the uplink BWP according to the starting frequency domain position configuration parameter and the number of FDM PRACH resources.

[0079] For example, in the uplink BWP, the terminal determines that the frequency domain starting position offset is 2 according to the network device indication information, the number of RBs occupied by one PRACH resource is 12, and the number of FDM PRACH resource is 4, then the terminal may determine four PRACH resources included in the uplink BWP, as shown in FIG. 1C.

[0080] (4) PRACH resources in the NR-U system:

[0081] Since in a shared spectrum, a unit channel bandwidth of a communication device when performing LBT may include 20 MHz, and since it is necessary to satisfy the channel occupied index requirements when performing signal transmission, a long sequence of PRACH sequences is introduced in the NR-U system. When the PRACH has a 15 kHz subcarrier spacing (SCS), the PRACH sequence length is 1151, and when the PRACH has a 30 kHz subcarrier spacing, the PRACH sequence length is 571.

[0082] The combination of PRACH subcarrier diversity and PUSCH subcarrier diversity supported in the shared spectrum and the number of RBs occupied by the corresponding PRACH resource are shown in Table 2 below. The number of RBs occupied by PRACH is expressed in RB PUSCH units.

[0083] Table 2

PRACH sequence length SCS PRACH (kHz) SCS PUSCH (kHz) Number of occupied RBs in PRACH 139 15 15 12 139 15 thirty 6 139 15 60 3 139 thirty 15 24 139 thirty thirty 12 139 thirty 60 6 571 thirty 15 96 571 thirty thirty 48 571 thirty 60 24 1151 15 15 96 1151 15 thirty 48 1151 15 60 24

[0084] In the NR-U system, since a guard band is introduced in the carrier, when the uplink BWP includes a plurality of RB sets, the uplink BWP may also include a guard band between two RB sets. Regarding the resource configuration of the existing random access procedure, it may be that the configured resource is located in a guard band in the uplink BWP. Therefore, in the NR-U system, the resource allocation of the random access procedure needs to be further studied.

[0085] With regard to the above problems, an embodiment of the present disclosure provides a wireless communication method, which will be described in detail below with reference to the accompanying drawings. This disclosure includes at least part of the following content.

[0086] Please refer to Figure 2A. FIG. 2A is a schematic flowchart of a resource configuration method provided by an embodiment of the present disclosure. The method includes the following:

[0087] S210. The network device sends configuration information corresponding to the uplink bandwidth portion (BWP) to the terminal device.

[0088] The uplink BWP may include at least two sets of resource blocks (RBs).

[0089] In particular, the uplink BWP may include an initial uplink BWP or an activated uplink BWP.

[0090] S220. After receiving the configuration information, the terminal device obtains frequency domain positions of the first frequency domain resource and N second frequency domain resource(s) in the uplink BWP according to the configuration information.

[0091] The first frequency domain resource may include a first guard band between two adjacent sets of RBs in the at least two sets of RBs, and every second frequency domain resource in the N second frequency domain resources may be used to transmit a first uplink physical channel The first uplink physical channel may include at least one of a physical random access channel (PRACH) and a message A physical uplink shared channel (msgA-PUSCH), and N is a positive integer. Optionally, N is a positive integer greater than or equal to 1. Optionally, the value of N can be one of 1, 2, 4, and 8.

[0092] In particular, the first guard band may include a guard band in the carrier.

[0093] Optionally, the first frequency domain resource includes an integer number of RBs, and/or the second frequency domain resource includes an integer number of RBs.

[0094] It can be seen that in this embodiment, configuration information corresponding to the uplink BWP is sent to the terminal device via the network device, and then the terminal device obtains frequency domain positions of the first frequency domain resource and N second frequency domain resource(s) ) frequency domain in the uplink BWP according to the configuration. Since the uplink BWP includes a guard band between two sets of RBs, the frequency domain position of the first frequency domain resource with the guard band and at least one second frequency domain resource in the uplink BWP are obtained through configuration information, which is useful for implementing the PRACH or msgA-PUSCH frequency domain resource configuration, and is useful for preventing the PRACH or msgA-PUSCH from being transmitted through the guard band.

[0095] In a possible example, the method may further include the following operations: if the first frequency domain resource and the second frequency domain resource overlap in the frequency domain, the second frequency domain resource cannot be used to transmit the first uplink physical channel; or if the first frequency domain resource and the second frequency domain resource do not overlap in the frequency domain, the second frequency domain resource may be used to transmit the first uplink physical channel.

[0096] In a possible example, the method may further include the following operations: if the first frequency domain resource and the second frequency domain resource overlap in the frequency domain, the second frequency domain resource is an invalid resource; or if the first frequency domain resource and the second frequency domain resource do not overlap in the frequency domain, the second frequency domain resource is a valid resource.

[0097] In a possible example, the configuration information may include first indicating information, and the first indicating information may be used to indicate a starting frequency domain position in the uplink BWP of at least one second frequency domain resource of the N second resource(s). ov) frequency domain.

[0098] In a possible example, the first indication information is used to indicate a starting frequency domain position in the uplink BWP of every second frequency domain resource of the N second frequency domain resource(s).

[00120] Optionally, for a two-step random access procedure, the terminal device determines the frequency domain position of the msgA-PUSCH resource in the uplink BWP in accordance with the network device configuration parameters, wherein if at least one RB corresponding to the first resource msgA -PUSCH overlaps in the frequency domain with at least one RB included in the guard band in the uplink BWP, then the first msgA-PUSCH resource may be considered an invalid msgA-PUSCH resource, or the terminal device cannot use the first msgA-PUSCH to send msgA-PUSCH to the network device, or the network device does not expect the terminal device to send msgA-PUSCH via the first msgA-PUSCH resource.

[00132] Optionally, when the PRACH sequence is a long sequence, a set of RBs including PRACH resources can be obtained in accordance with the number of PRACH resources frequency division multiplexed in the same time unit. For example, if we assume that the number of PRACH resources frequency division multiplexed in the same time unit is 2, then the first 2 sets of RBs in the uplink BWP include PRACH resources.

Optionally, N pieces of frequency domain starting position indicating information are respectively used to indicate the frequency domain offset of the N PRACH resources in the uplink BWP relative to the first of the PRBs (ie, PRB 0) of the uplink BWP in the frequency domain.

[00135] Optionally, for a two-step random access process, the terminal device determines a frequency domain position of the msgA-PUSCH resource in the uplink BWP in accordance with the configuration parameters of the network device, wherein the msgA-PUSCH resource is located in a set of RBs in the uplink BWP communications.

[00136] Optionally, the network device configuration parameters include RB set indication information corresponding to the msgA-PUSCH resource.

[00141] Optionally, one set of RBs corresponds to one LBT frequency band, or one set of RBs corresponds to a 20 MHz frequency band.

[00142] FIG. 2C uses the PRACH resource configuration as an example to give an example of Embodiment 2. As shown in FIG. 2C, the uplink BWP includes 2 sets of RBs, with RB set 0 including 51 RBs, RB set 1 including 50 RBs, and a guard band of 5 RBs included between the two RB sets. . In the uplink BWP, the number of RBs allocated to one PRACH resource is 48, the uplink BWP includes two PRACH resources, and each PRACH resource is located in a set of RBs in the uplink BWP. In particular, when a network device configures a PRACH resource in an uplink BWP for a terminal device, it may include at least one of the following methods:

[00143] Method 1: The network device indicates that the RB sets including PRACH resources are RB set 0 and RB set 1, and indicates that the first starting position in the frequency domain is 1.

[00144] Method 2: The network device indicates that the RB sets including PRACH resources are RB set 0 and RB set 1, and the protocol agrees that the first starting position in the frequency domain is 1.

[00145] Method 3: The network device indicates that the number of PRACH resources frequency division multiplexed in the same time unit is 2, and the terminal device receives according to the information that the RB sets including the PRACH resources represent are set 0 RB and set 1 RB. The starting position of the first frequency region may be specified or agreed upon by the protocol.

[00146] Method 4: The network device indicates that the frequency domain offset of two PRACH resources in the uplink BWP relative to the first of the uplink BWP PRBs in the frequency domain, that is, the starting position of the second frequency domain, includes 1 and 57.

[00147] Unlike the technical solutions described in Embodiment 1 and Embodiment 2 above, the present disclosure also considers a situation where a terminal device may be able to perform uplink transmission through only one set of RBs, and for details, refer to to embodiment 3.

[00148] Embodiment 3:

[00149] In an NR-U system, the uplink BWP (eg, the initial uplink BWP or the activated uplink BWP) may include one or more sets of RBs, but it may be possible for the terminal device to perform uplink transmissions only through one set of RBs. When the uplink BWP, eg, the initial uplink BWP, includes multiple RB sets, the network device may allocate resources in one or more RB sets when scheduling transmission Msg3 for the terminal device. Therefore, for terminal devices with limited capabilities, such as terminal devices that have only one set of RBs for uplink transmission, the network device must allocate one set of RBs to those terminal devices instead of allocating multiple sets of RBs for Msg3 transmission. However, in a random access procedure, the network device may not know the functional characteristics of the terminal device sending the PRACH.

[00150] Thus, in this embodiment, the terminal device may report the functional characteristics of the terminal device to the network device through at least one of PRACH time domain resources, PRACH frequency domain resources, PRACH sequence, and msgA-PUSCH, such that the network device allocates the resources uplink transmissions for the terminal device in accordance with the received PRACH and/or msgA-PUSCH.

[00151] For example, the PRACH resources may include a first set of PRACH resources and a second set of PRACH resources, wherein the PRACH resources included in the first set of PRACH resources and the second set of PRACH resources differ in at least one aspect from time domain, frequency domain area and code area (ie PRACH sequence). The first set of PRACH resources corresponds to a first terminal functionality, eg, supports transmission through only one set of RBs, and the second set of PRACH resources corresponds to a second terminal functionality, eg, supports simultaneous transmission across multiple RB sets. When the terminal device has the first terminal capability, the terminal device selects PRACH resources from the first set of PRACH resources for PRACH transmission; or when the terminal device has the second terminal capability, the terminal device selects PRACH resources from the set of second PRACH resources for PRACH transmission.

[00152] Optionally, the functionality reported by the terminal device includes: support for transmission across one set of uplink RBs or support for simultaneous transmission across more than one set of uplink RBs. Or, the functional characteristic reported by the terminal device includes whether to support simultaneous transmission through multiple sets of uplink RBs. Or the functional characteristic reported by the terminal device includes: the number of RB sets through which simultaneous uplink transmission is supported.

[00153] Optionally, if the functionality reported to the network device by the terminal device supports transmission through only one set of uplink RBs, when the terminal device receives RAR authorization information or authorization information scrambled via TC-RNTI to schedule Msg3 for the terminal devices, the transmission resource corresponding to Msg3 must be limited to one set of RBs, or the terminal device does not expect the transmission resource corresponding to Msg3 to be located in multiple sets of RBs. Or, if the capability received by the network device and reported by the terminal device supports transmission through only one set of uplink RBs, when the network device schedules Msg3 for the terminal device by RAR authorization information or authorization information scrambled by TC-RNTI, the transmission resource shall be limited to one set of RBs.

[00154] Optionally, one set of RBs corresponds to one LBT frequency band, or one set of RBs corresponds to a 20 MHz frequency band.

[00155] Unlike the technical solutions described above in Embodiment 1, Embodiment 2 and Embodiment 3, this disclosure also considers the case where, when a terminal device is configured with interleaved uplink transmission, the network device allocates resources to the terminal device frequency domain. In particular, see Embodiment 4 for details.

[00156] Embodiment 4:

[00157] When a terminal device is configured with interleaved uplink transmission, the manner in which the network device allocates frequency domain resources to the terminal device includes the following: if the uplink BWP includes multiple sets of RBs, for interleaved PUSCH transmission in the BWP The uplink frequency domain resource allocation (FDRA) in the grant information for frequency domain resource allocation of the PUSCH may include X+Y bits, where X bits are used to indicate the allocated interlace index and Y bits are used to indicate which the set or sets of RBs in the uplink BWP are allocated to the terminal device. However, in a random access process, when a network device allocates PUSCH resources to transmit Msg3 for a terminal device through RAR authorization information or authorization information scrambled by TC-RNTI, the grant information may only include X bits to indicate the allocated interlace index, although not includes Y-bit information used to indicate the set of RBs in the uplink BWP.

[00158] In this case, a possible implementation method is that the terminal device may assume that the interlace index indicated by the X bit in all RB sets included in the uplink BWP is allocated to it for transmission of Msg3, and the terminal device may perform detection channel with respect to the channels corresponding to all RB sets included in the uplink BWP, and transmit Msg3 to the network device across all RB sets after it is detected that the channels corresponding to all RB sets are not occupied.

[00159] In this case, another possible implementation is that the terminal device may assume that the interlace index indicated by the X bit in all RB sets included in the uplink BWP is allocated to it for transmission of Msg3, and the terminal device may perform channel discovery regarding channels corresponding to all RB sets included in the uplink BWP, and transmit Msg3 to the network device through the RB set that is detected as idle. Optionally, if the terminal device detects that channels corresponding to a plurality of RB sets included in the uplink BWP are idle during the channel discovery process, then the terminal device may determine, in accordance with preset rules, the RB set to transmit Msg3. such as the RB set with the lowest index from the RB set corresponding to idle channels, or the terminal device may select the RB set to transmit Msg3 itself. Thus, the terminal device may have a higher probability of accessing the channel when transmitting Msg3. Accordingly, the network device can determine the RB set used by the terminal device to send the Msg3 message by performing discovery to find the RB set included in the uplink BWP. Optionally, the network device may perform detection by searching for Msg3 in accordance with the ascending order of the RB set indices.

[00160] Optionally, one set of RBs corresponds to one LBT frequency band, or one set of RBs corresponds to a 20 MHz frequency band.

[00161] Unlike the technical solutions described above in Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4, this disclosure also considers the case where the uplink BWP includes one set of RBs, the network device configures resources PRACH and/or msgA-PUSCH resource for the terminal device, see Embodiment 5 for details.

[00162] Embodiment 5:

[00163] The network device sends configuration information corresponding to the uplink bandwidth portion (BWP) to the terminal device, wherein the uplink BWP includes a set of resource blocks (RBs). The uplink BWP may include an initial uplink BWP or an activated uplink BWP. After receiving the configuration information, the terminal device obtains frequency domain positions of N second frequency domain resources in the uplink BWP according to the configuration information.

[00164] Each of the N second frequency domain resources may be used to transmit a first uplink physical channel, and the first uplink physical channel may include at least one of a physical random access channel (PRACH) and a physical uplink shared channel message link A (msgA-PUSCH), N is a positive integer.

[00167] In a possible example, the configuration information may include second indication information, and the second indication information may be used to indicate that the number of second frequency domain resources included in the uplink BWP is N.

[00168] In a possible example, the second indicating information may be used to indicate that the number of second frequency domain resources included in the uplink BWP is N=1, that is, the uplink BWP includes one second frequency domain resource. Optionally, the first indication information may be used to indicate a starting frequency domain position of a second frequency domain resource in the uplink BWP. Optionally, the second frequency domain resource includes PRACH resources, wherein the PRACH SCS is 15 kHz and the PRACH sequence length is 1151, or the PRACH SCS is 30 kHz and the PRACH sequence length is 571.

[00169] In a possible example, when the second frequency domain resource includes PRACH resources such that the PRACH SCS is 15 kHz and the PRACH sequence length is 1151, or the PRACH SCS is 30 kHz and the PRACH sequence length is 571, the second indicating information included in the configuration information indicates that N=1 or the number of second frequency domain resources included in the uplink BWP is N=1. Or in this case, the terminal device does not expect that the number N of second frequency domain resources included in the uplink BWP is greater than 1.

[00170] Optionally, the terminal device determines the frequency domain position of the PRACH resource (also called RO, RACH event, or RACH transmit opportunity) in accordance with the PRACH resource frequency domain starting position configuration parameter (e.g., high layer parameter msg1-FrequencyStart or msgA-RO-FrequencyStart ) reported by the network device. Specifically, the frequency domain initial position configuration parameter is used to indicate the frequency domain offset of the first frequency domain PRACH resource in the uplink BWP (eg, the initial uplink BWP or the activated uplink BWP) relative to the first PRB (i.e. .PRB 0) Uplink BWP. The network device may also report the amount of frequency division multiplexing (FDM) PRACH resources in the same unit of time through a top layer parameter (eg, msg1-FDM or msgA-RO-FDM ). The terminal device can determine the frequency domain position of the PRACH resource included in the uplink BWP according to the frequency domain starting position configuration parameter and the number of FDM PRACH resources.

[00171] Optionally, if the PRACH sequence length is 1151 or if the PRACH sequence length is 571, then the terminal device expects that the number of frequency division multiplexing (FDM) PRACH resources in the same time unit is 1, or the terminal device expects that a network device configuration parameter such asmsg1-FDM, indicates 1 ormsgA-RO-FDM indicates 1, or the terminal device does not expect the network configuration parameterdevices,such asmsg1-FDM ormsgA-RO-FDM indicates a value other than 1.
