[0069] For better understanding, the relevant concepts and principles that may be involved in the embodiments of the present application are explained below.

[0070] Random access process:

[0071] In the related art, the random access process may be a contention-based random access process or a non-contention-based random access process. The random access process may be a four-step random access process (also called a Type-1 random access process) or a two-step random access process (also called a Type-2 random access process).

[0072] In the competitive 4-step random access process (Random Access Channel, RACH), the UE first sends message 1 (msg1) to the network, including a preamble; after the network detects the preamble, it will send a msg2 / Random Access Response (RAR) message, including the number of the preamble detected by the network and the uplink radio resources allocated to the UE to send message 3 (msg3); after receiving message 2 (msg2), the UE confirms that at least one of the numbers of the preamble carried in msg2 is consistent with the number of the preamble sent by itself, and then sends msg3 containing contention resolution information according to the resources indicated by RAR; after receiving msg3, the network will send message 4 (msg4) containing contention resolution information; after receiving msg4, the UE confirms that the resolution information is consistent with that sent by itself in msg3, and the 4-step random access is completed.

[0073] The network includes uplink (UL) grant information in the RAR to indicate the MSG3 physical uplink shared channel (PUSCH) scheduling information, and includes the random access process preamble ID (RACH preamble ID, RAPID), temporary cell radio network temporary identifier (Temporary Cell Radio Network Temporary Identifier, TC-RNTI), timing advance (Timing Advance, TA) and other information. If the network does not receive the MSG3 PUSCH, it can schedule the retransmission of the MSG3 PUSCH in the TC-RNTI scrambled physical downlink control channel (PDCCH).

[0074] For the contention random access process, different UEs randomly select preambles for transmission, so different UEs may select the same preamble to send on the same time-frequency radio resources (random access opportunity (RACH Occasion, RO) resources), which can be understood as a UE preamble conflict. In this case, different UEs will receive the same RAR, and at this time, different UEs will transmit MSG3 PUSCH according to the scheduling information in the RAR UL grant. Since the relevant technology does not support repeated transmission of MSG3 PUSCH, the network can only decode a PUSCH (including contention resolution information) sent by one UE on one MSG3 PUSCH scheduling resource, so the network will include the contention resolution information received in MSG3 in MSG4. If the contention resolution information in MSG4 received by the UE matches the contention resolution information sent by the UE in MSG3 PUSCH, the UE considers that the contention resolution is successful. If they do not match, the contention resolution is considered unsuccessful.

[0075] If the contention resolution is unsuccessful, the UE reselects RACH transmission resources, performs physical random access channel (PRACH) transmission, and makes the next random access attempt.

[0076] In NR Rel-16, the two-step random access process 2-step RACH was introduced. The first step is that the UE sends message A (MsgA) to the network side. After receiving MsgA, the network side sends message B (MsgB) to the UE. If the UE does not receive MsgB within a certain period of time, the UE will accumulate the counter that counts the number of times MsgA is sent and resend MsgA. If the counter that counts the number of times MsgA is sent reaches a certain threshold, the UE will switch from the 2-step random access process to the 4-step random access process. MsgA includes the MsgA preamble part and the MsgAPUSCH part. The preamble part is sent on the RO used for 2-step RACH, and the PUSCH part is sent on the MsgA PUSCH resources associated with the sending of the MsgA preamble and the RO. MsgA PUSCH resources are a group of PUSCH resources configured relative to each PRACH time slot, including time-frequency resources and demodulation reference signal (DMRS) resources.

[0077] Selection of random access resources and mapping of synchronization signal blocks (Synchronization Signal and PBCH block, SSB) to RO:

[0078] In NR, a cell can configure multiple frequency division multiplex (FDM) physical random access channel transmission opportunities (PRACH transmission occasions, or PRACH Occasions) at a time domain position for transmitting PRACH. For simplicity, they are referred to as ROs. At one time, the number of ROs that can perform FDM can be: {1, 2, 4, 8}. Figure 1b As shown, at one moment, there are 8 RO resources distributed on different frequencies.

[0079] The random access preamble can only be transmitted on the time domain resources (i.e., RO resources) configured by the parameter PRACHConfigurationIndex. The random access preamble can only be transmitted on the frequency domain resources configured by the parameter prach-FDM. The PRACH frequency domain resources n RA ∈{0,1,...,M-1}, where M is equal to the high-level parameter prach-FDM. At the time of initial access, the PRACH frequency domain resource n RA The PRACH frequency domain resources are numbered in ascending order starting from the lowest frequency RO resource in the initial active uplink bandwidth part. Otherwise, the PRACH frequency domain resources are numbered in ascending order starting from the lowest frequency RO resource in the active uplink bandwidth part. Figure 1b As shown, the RO resources are numbered RO#0 to RO#7 in order from low to high frequency.

[0080] In NR, there is an association between the RO and the SSB actually sent. One SSB may be associated with multiple ROs, or multiple SSBs may be associated with one RO (in this case, different SSBs correspond to different Preamble codes). Usually, the base station can use different beams to send different SSBs, and the corresponding UE sends the Preamble on the RO associated with the SSB. In this way, the UE selects the RO / "RO and preamble combination" associated with the SSB with a good signal according to the strength of the received downlink beam / SSB, and sends msg1. In this way, the network can determine the SSB selected by the UE based on the RO / "RO and preamble combination" of the received Preamble. And send msg2 on the downlink beam corresponding to the SSB to ensure the reception quality of the downlink signal.

[0081] by Figure 1b For example, the number of FDM ROs at a time is 8, and the number of SSBs actually transmitted is 4, namely SSB#0, SSB#1, SSB#2, SSB#3, and each SSB is associated with 2 ROs. If the UE determines to send PRACH / msg1 / Preamble on the RO corresponding to SSB#0, the UE selects an RO from RO#0 and RO#1 to send PRACH.

[0082] by Figure 1c For example, the number of FDM ROs at a time is 2, and the number of SSBs actually transmitted is 8, namely SSB#0, SSB#1, ..., SSB#7, and every 2 SSBs are associated with 1 RO. When multiple SSBs share one RO, the preamble sets associated with the multiple SSBs are different, that is, the same preamble cannot belong to the preamble sets associated with different SSBs at the same time: Figure 1c Taking RO#0 as an example, there are 60 preambles associated with SSB, among which preambles with indexes 0 to 29 are associated with SSB#0, and preambles with indexes 30 to 59 are associated with SSB#1.

[0083] Before sending PRACH, the UE first performs resource selection. First, based on the reference signal received power (RSRP) of the received beam / SSB, it selects an SSB with RSRP higher than the threshold. If the RSRP of multiple SSBs is higher than the threshold, the terminal can select any SSB with RSRP higher than the threshold. When there is no SSB with RSRP higher than the threshold, the UE selects an SSB based on the implementation.

[0084] Based on the configuration of the network (NW), the UE obtains the correspondence between the SSB and the RO; after selecting the SSB, the RO corresponding to the selected SSB is used as the RO for sending PRACH / Preamble. If the selected SSB is associated with multiple ROs, the terminal can select one of the ROs for PRACH / Preamble transmission.

[0085] For example: Figure 1b In the example shown, assuming that the UE selects SSB#1, the UE can select one from RO#2 and RO#3 to send PRACH / Preamble; Figure 1c In the example shown, if the UE selects SSB#1, the UE can select the available RO (RO#0 or RO#4) associated with SSB#1 that is closest to the current time to send PRACH / Preamble.

[0086] In the selected RO, the UE selects a preamble from the preamble set associated with the selected SSB to send the PRACH. Figure 1c In the example, if one RO is associated with two SSBs, then the preambles in the available preamble set associated with the SSB in one RO will be divided into two subsets, each corresponding to one SSB. The UE will select a preamble sequence in the preamble subset corresponding to the selected SSB for PRACH transmission.

[0087] In the relevant 5G technology, there are some rules to resolve the conflict between PRACH and other signals or TDD configuration:

[0088] If after an integer number of SS / PBCH block (SSB) indices are mapped to a PRACH occasion mapping cycle within an association period, there is a set of PRACH occasions or PRACH sequences that are not mapped to an SS / PBCH block index (SSB index), then no SS / PBCH block index is mapped to a PRACH occasion or PRACH sequence. These PRACH resources will not be available for PRACH transmission.

[0089] The associated pattern period includes one or more associated periods and is determined so that the pattern between PRACH occasions and SS / PBCH block indices (SSB indexes) is repeated at most once every 160 milliseconds. PRACH occasions (if any) that are not associated with SS / PBCH block indices after an integer number of associated periods are not used for PRACH transmission.

[0090] If the MsgA PUSCH occasion does not overlap in time and frequency with any valid PRACH occasions associated with the first type random access procedure or the second type random access procedure, the MsgA PUSCH occasion is valid. This means that when PRACH overlaps with MsgA PUSCH resources, PRACH is transmitted instead of MsgA PUSCH.

[0091] For operation on a single carrier in an unpaired spectrum (Time Division Duplex (TDD)), if the UE is configured by a higher layer to receive PDCCH, Physical downlink shared channel (PDSCH), Channel State Information Reference Signal (CSI-RS) or Downlink Positioning Reference Signal (DL-PRS) in a set of symbols in a certain slot, then if the UE does not detect a downlink control information (DCI) format indicating that the UE sends PUSCH, PUCCH, PRACH or Sounding Reference Signal (SRS) in at least one symbol in this set of symbols, then the UE receives PDCCH, PDSCH, CSI-RS or DL-PRS, otherwise the UE does not receive PDCCH, PDSCH, CSI-RS or DL-PRS.

[0092] For operation on a single carrier in unpaired spectrum, if the UE is configured by higher layers to transmit SRS, PUCCH, PUSCH or PRACH in a group of symbols in a slot, and the UE detects a DCI format that indicates that the UE receives CSI-RS or PDSCH from a subset of this group of symbols, then:

[0093] If the UE does not have the [partial cancellation] capability, then if the time interval between the first symbol in the set (a group of symbols for transmitting SRS, PUCCH, PUSCH or PRACH) and the last symbol of the control resource set (CORESET) detected by the UE in the DCI format does not exceed T proc,2, the UE does not expect to cancel the transmission of PUCCH or PUSCH or PRACH in the set; otherwise, the UE cancels the PRACH transmission, or decides to cancel the actual repeated transmission of PUCCH, PUSCH, or PUSCH according to the relevant protocol;

[0094] If the UE has the [partial cancellation (partialCancellation)] capability, if the time interval between a part of the symbols in the set (a group of symbols sending SRS, PUCCH, PUSCH or PRACH) and the last symbol of the CORESET detected by the UE in the DCI format does not exceed T proc,2 , the UE does not expect to cancel the transmission of PUCCH, PUSCH or PRACH on this part of symbols; for symbols outside this part of symbols, the UE cancels the PRACH transmission, or decides to cancel the actual repeated transmission of PUCCH, PUSCH, or PUSCH according to the relevant protocol.

[0095] PRACH repetition:

[0096] In 3GPP NR Rel-18, PRACH repetition is introduced. For PRACH repetition, the UE needs to repeatedly send the Preamble on multiple ROs at different positions in the time domain associated with the same SSB. The number of PRACH repetitions can be {2, 4, 8}. After the UE determines the number of PRACH repetitions, it needs to determine the RO set. The number of valid ROs in the RO set is equal to the number of PRACH repetitions.

[0097] Assuming that the number of PRACH repetitions is N1, the overall determination rule of the RO group in the time window X is: first, determine the starting RO of the first RO group, and then determine the remaining N-1 ROs of the first RO group. Then determine the starting RO and the remaining ROs of other RO groups in turn. The remaining N1-1 ROs of each RO group are ROs associated with the same SSB, the same frequency position, and the same associated Preamble set as the starting RO. After the first RO group is determined, the determination of the remaining RO groups is related to whether the time offset is configured.

[0098] If time offset is not configured, for each SSB, the first valid RO in the time window X is used as the starting RO of the first RO group, and the first RO group is determined based on the starting RO. Then, on the other ROs except the previous RO group, the starting ROs of the subsequent RO groups are determined in the order of increasing frequency domain positions first and then increasing time domain positions within the time window X, and the subsequent RO groups are further determined. For example, Figure 1d In the example, assuming that the number of PRACH repetitions is 2, for SSB#0, the RO group can be determined as follows: Figure 1d shown.

[0099] If the time offset is configured, for each SSB, the first valid RO found in the time window X in the order of frequency domain first and time domain second is used as the starting RO of the first RO group, and then the first RO group is determined based on the starting RO. Then, the starting RO of the subsequent RO groups is determined in the order of frequency domain first and time domain second on the other ROs except the previous RO group. For the same SSB, the starting RO of the nth RO group at the same frequency position is the RO that is time offset from the starting RO of the n-1th RO group at the frequency position. The time offset is defined as the number of valid ROs associated with the same SSB in the time domain. For example, Figure 1e In the example, assuming that the number of PRACH repetitions is 2 and time offset = 3, for SSB#0, the RO group can be determined as follows: Figure 1e shown.

[0100] Duplex mode enhancements:

[0101] In 5G mobile communication systems, full duplex enhancement technology is used to adapt to diverse scenarios and business requirements. The main scenarios of 5G include enhanced mobile broadband (eMBB), ultra-reliable and low latency communications (URLLC), and massive machine type communications (mMTC). These scenarios require the system to have high reliability, low latency, large bandwidth, and wide coverage.

[0102] In NR, configuring full-duplex operation can significantly improve the latency and coverage performance of TDD systems.

[0103] Subbands non-overlapping Full duplex: can improve transmission delay and enhance coverage.

[0104] For a DL slot (configured by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated), the network configures the DL bandwidth part (Bandwidth Part, BWP) for the UE. For a UL slot, the network configures the UL BWP for the UE.

[0105] For full duplex scenarios, such as Figure 1f As shown, there may be the following cases:

[0106] Case 1: Configure DL BWP, that is, slot 1;

[0107] Case 2: Configure DL BWP and UL subband, that is, slot 2.

[0108] For a UL slot (configured by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated), such as Figure 1g As shown, there can be the following cases:

[0109] Case 3: Configuring UL BWP is time slot 4;

[0110] Case 2: Configure UL BWP and DL subband, that is, slot 5.

[0111] For SBFD operation, an SBFD subband consists of one RB or a set of consecutive RBs with the same transmission direction.

[0112] The time unit (e.g., slot or symbol) in which the base station (gNB) uses SBFD operation may be referred to as a SBFD time unit (e.g., slot or symbol).

[0113] Please refer to Figure 1h ,For Rel-15, the base station and UE can only send or receive at a time;

[0114] For Rel-18 gNB side full-duplex, the gNB can send and receive at the same time, and the UE side can only use half-duplex mode, that is, it can only send or receive at a time;

[0115] For full-duplex on the UE side, the gNB and UE can transmit and receive simultaneously.

[0116] For full-duplex at the UE side, a larger guard band (GB) (larger than the GB of the base station FD) may be required to suppress self-interference, such as Figure 1i shown.

[0117] For a communication device, simultaneous UL reception and DL transmission will cause self-interference. In order to ensure transmission in the interfered direction, the communication device needs to have the ability to eliminate self-interference, such as reserving a guard band between the receiving band and the transmitting band, but this will reduce the UE throughput.

[0118] The current duplex enhancement mainly considers the connected UE and the network side supports full duplex and the UE side supports half duplex.

[0119] In order to improve the flexibility of UE to use duplex mode in idle and inactive states, enhanced duplex mode can be configured in UE idle / inactive state, or dynamically configured in random access phase. At this time, it is necessary to consider how to configure enhanced duplex mode suitable for cell level, whether PRACH can be sent on the newly configured subband, and how to configure the multiple PRACH resource types introduced. In addition, it is necessary to consider how to determine the RO group for repeated transmission when PRACH is repeatedly transmitted.

[0120] The resource configuration method, apparatus and related equipment provided in the embodiments of the present application are described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0121] Please refer to Figure 2 , Figure 2 1 is a flow chart of a resource configuration method provided in an embodiment of the present application, and the method is applied to a terminal. Figure 2 As shown, the method comprises the following steps:

[0122] Step 201: A terminal receives first configuration information sent by a network-side device.

[0123] The first configuration information is used to determine the subband in the enhanced duplex mode. In an embodiment of the present application, the enhanced duplex mode may be an SBFD mode, or a mode in which the network side supports full-duplex and the UE side supports half-duplex, or other duplex modes that are different from time division duplex (TDD) or frequency division duplex (FDD).

[0124] Step 202: The terminal determines a subband in an enhanced duplex mode according to the first configuration information.

[0125] The first configuration information includes at least one of the following:

[0126] a period of the enhanced duplex mode;

[0127] the width of the sub-band;

[0128] The starting frequency domain position of the subband, such as the starting physical resource block (PRB);

[0129] The size of the guard band between the sub-band and other bandwidths, wherein the other bandwidths are bandwidths other than the sub-band in the bandwidths configured in the enhanced duplex mode;

[0130] The attribute of the subband, the attribute being related to the transmission direction, such as a downlink subband of an uplink timeslot, or an uplink subband of a downlink timeslot;

[0131] The time slot pattern of the subband configured within the period of the enhanced duplex mode.

[0132] Exemplarily, the network side device may configure the starting frequency domain position of the subband in the enhanced duplex mode through the first configuration information, and then the terminal can determine the subband in the enhanced duplex mode based on the first configuration information; or, the first configuration information sent by the network side device also includes the width of the subband, and then the terminal can determine the specific frequency domain position of the subband in the enhanced duplex mode based on the width of the subband and the starting frequency domain position of the subband.

[0133] Alternatively, the first configuration information may also include the period of the enhanced duplex mode and the starting frequency domain position of the subband. Based on the first configuration information, the terminal can determine which time units are the enhanced duplex mode and the frequency domain position of the subband under the enhanced duplex mode.

[0134] Alternatively, the first configuration information may include the starting frequency domain position of the subband in the enhanced duplex mode and the size of the guard band between the subband and other bandwidths, so that the terminal can determine the frequency domain position of the subband in the enhanced duplex mode and the frequency domain position of other bandwidths based on the first configuration information.

[0135] For another example, the first configuration information may include a time slot mode of a subband configured in a period of the enhanced duplex mode. For example, a certain mode may be configured by a network-side device or a certain mode in a set of time slot modes specified by a network-side device indication protocol may be used to determine which time slots in the period of the enhanced duplex mode will be configured with corresponding subbands, so that the terminal can determine the subbands in the enhanced duplex mode based on the first configuration information. Alternatively, the time slots of the subbands in the enhanced duplex mode configured by the first configuration information are all downlink time slots or all uplink time slots, or an uplink time slot subset or a downlink time slot subset is determined according to a certain mode.

[0136] It is understandable that the specific information content included in the first configuration information may also be other possible situations, which are not listed in detail in the embodiments of the present application.

[0137] In an embodiment of the present application, the network side device sends the above-mentioned first configuration information, and then the terminal can determine the subband under the enhanced duplex mode according to the first configuration information, thereby defining how to configure the frequency domain resources on the terminal side under the enhanced duplex mode, so that the terminal can flexibly use the duplex mode, effectively improving the transmission flexibility and transmission performance of the terminal.

[0138] It should be noted that the state of the terminal is not limited in the embodiment of the present application. For example, the terminal may be a terminal in all states, including a connected UE, an idle UE, an inactive UE, etc. For example, the network side device may broadcast the first configuration information, and then the terminals receiving the first configuration information can determine the subband in the enhanced duplex mode based on the first configuration information, thereby effectively improving the transmission performance of the terminal.

[0139] Alternatively, in the embodiment of the present application, the terminal is an idle or inactive terminal, so that the idle or inactive terminal can determine the subband in the enhanced duplex mode based on the first configuration information. In this way, the enhanced duplex mode can be configured when the terminal is in an idle or inactive state, so that the terminal can flexibly use the duplex mode in the idle or inactive state, thereby improving the transmission performance of the idle or inactive terminal.

[0140] Optionally, when the first configuration information includes a guard band size between the subband and other bandwidths, the terminal satisfies any one of the following:

[0141] The terminal is in SBFD mode;

[0142] The terminal is in half duplex (HD) mode.

[0143] It should be noted that for the network side (gNB) SBFD time slot, when the terminal performs SBFD and when the terminal performs HD, the size of the protection band between the subband and other bandwidths configured by the network side device may be different. At this time, it can be configured separately for these two modes.

[0144] Optionally, the first configuration information is sent through at least one of the following:

[0145] The system message, for example, may be to introduce an additional system message field in a system information block (SIB) 1 to indicate the first configuration information;

[0146] Terminal-specific messages;

[0147] Physical downlink control channel PDCCH;

[0148] Physical random access channel PRACH configuration;

[0149] A dedicated configuration table, where the dedicated configuration table is used to specify the first configuration information. The dedicated configuration table may be a network-side device configuration or a protocol definition.

[0150] Exemplarily, the first configuration information may be sent through a terminal dedicated message. For example, for an inactive terminal, after the terminal enters the Radio Resource Control (RRC) release, the first configuration information may be configured in the RRC release message, and some channels may be scheduled on the subband of the additionally configured enhanced duplex mode to reduce the transmission delay. For another example, in a non-contention random access (Contention Free Random Access, CFRA) process triggered by a higher layer, the first configuration information may be configured in the corresponding higher layer signaling, and some signal transmissions may be placed on the subband of the additionally configured enhanced duplex mode to reduce the delay; the higher layer signaling may be a handover command, a beam failure recovery (Beam Failure Recovery, BFR) configuration, etc.

[0151] Alternatively, the first configuration information may also be sent via a PDCCH. For example, in a PDCCH ordered CFRA process, the first configuration information may be sent via a corresponding PDCCH order.

[0152] Alternatively, the first configuration information may also be sent through PRACH configuration. For example, the uplink subband in the downlink time slot is determined by the RO appearing in the downlink time slot as the subband in the enhanced duplex mode; for another example, all PRBs occupied by the corresponding RO in the downlink time slot configured by the RO are considered to be configured as uplink subbands, and the RO is considered to be valid.

[0153] Optionally, the PRACH configuration includes a PRACH configuration table, and the PRACH configuration table includes the first configuration information. For example, a column of information may be added to the PRACH configuration table to indicate which time slots will have the configuration of the subband in the enhanced duplex mode, the size and frequency domain position of the subband, etc., and the column of information added to the PRACH configuration table is also the first configuration information.

[0154] In the embodiment of the present application, the first configuration information may include a guard band size between the subband and other bandwidths in the enhanced duplex mode. Optionally, the guard band between the subband and other bandwidths is determined based on at least one of the following:

[0155] The guard band configured in the PRACH configuration table;

[0156] At least one RO.

[0157] That is, a guard band between the subband and other bandwidths may be configured in the PRACH configuration table, or at least one RO may be used as a guard band between the subband and other bandwidths.

[0158] Optionally, the at least one RO is at least one RO at the edge of a bandwidth occupied by the PRACH.

[0159] Optionally, when a guard band between the subband and other bandwidths is determined based on the at least one RO, the RO satisfies any one of the following:

[0160] The RO is a valid RO, and the RO can be used to implement SSB to RO mapping, but is not used for actual PRACH transmission;

[0161] The RO is a valid RO, and the RO can be used to implement SSB to RO mapping, but whether the RO is used for actual PRACH transmission depends on the first condition;

[0162] The RO is not a valid RO and is not used to implement SSB to RO mapping.

[0163] Optionally, the first condition includes at least one of the following:

[0164] whether the time interval or frequency domain interval between the RO and the SSB is less than or equal to a preset value, for example, if the time interval or frequency domain interval between the RO and the SSB is less than or equal to the preset value, the RO is used for actual PRACH transmission;

[0165] whether there is transmission of SSB or other downlink common channels or signals on the other bandwidths, for example, if there is transmission of SSB or other downlink common channels or signals on the other bandwidths, the RO is used for actual PRACH transmission;

[0166] Whether the terminal receives SSB or other downlink common channels or signals on the other bandwidth, for example, if the terminal receives SSB or other downlink common channels or signals on the other bandwidth, the RO is used for actual PRACH transmission.

[0167] It should be noted that SSB and SS / PBCH block can be used interchangeably, and SSB can also be any signal module that at least includes a synchronization signal and / or a downlink broadcast channel.

[0168] In the embodiment of the present application, the method may further include:

[0169] The terminal receives second configuration information sent by the network side device, where the second configuration information is used to configure at least one RO type, and the at least one RO type includes at least one of the following:

[0170] RO present in the uplink timeslot;

[0171] RO exists on time slots with flexible symbols;

[0172] RO present in the uplink subband of the downlink timeslot;

[0173] There is no RO on the uplink subband of the downlink timeslot.

[0174] In the embodiment of the present application, the network side device configures at least one RO type through the second configuration information, and then the terminal can determine at least one RO type in the enhanced duplex mode based on the second configuration information. The solution provided in the embodiment of the present application, that is, defines and clarifies the configuration method of RO resources in the enhanced duplex mode, is more helpful to improve the transmission performance of the terminal.

[0175] Optionally, in a case where the at least one RO type includes an RO present on an uplink subband of a downlink timeslot, there is no SSB on the downlink timeslot, or there is an SSB on the downlink timeslot.

[0176] Optionally, the at least one RO type is configured by any of the following:

[0177] Independent PRACH configuration resources, wherein different RO types are configured by different independent PRACH configuration resources;

[0178] A common PRACH configuration resource, wherein different RO types are configured through the common PRACH configuration resource.

[0179] Exemplarily, one or more RO types may be configured through independent PRACH configuration resources. For example, for PRACH resources on an uplink subband, PRACH configuration resource 1 may be used for configuration; for PRACH resources on a non-uplink subband, PRACH configuration resource 2 may be used for configuration.

[0180] Alternatively, one or more RO types may be configured through a common PRACH configuration resource. For example, two different types of ROs may be configured through the same PRACH configuration resource (ie, a common PRACH configuration resource): a PRACH resource on an uplink subband and a PRACH resource on a non-uplink subband.

[0181] In the embodiment of the present application, two configuration modes for the RO type are effectively defined, making the configuration of the RO type more flexible.

[0182] Optionally, in the case of PRACH repetition, the method further includes:

[0183] The terminal determines an RO group from the at least one RO type based on the second configuration information to determine at least one resource for PRACH transmission; wherein the determination of the RO group satisfies at least one of the following:

[0184] The RO group includes different RO types;

[0185] The RO group includes the same RO type;

[0186] The RO types included in the RO group are mapped to the same downlink reference signal;

[0187] The RO types included in the RO group are mapped to different downlink reference signals.

[0188] It can be understood that the second configuration information is used to configure at least one RO type. After receiving the second configuration information sent by the network side device, the terminal can determine the RO group from the at least one RO type configured based on the second configuration information. The RO group may refer to an RO type set including multiple RO types (which may be the same or different).

[0189] Exemplarily, the RO group determined by the terminal may include different RO types. For example, the RO group includes ROs existing in an uplink timeslot and ROs existing in an uplink subband of a downlink timeslot, and so on.

[0190] Alternatively, the RO group determined by the terminal must include the same RO type, for example, the two RO groups included in the RO group are ROs existing in the uplink timeslot; for another example, the terminal determines multiple RO groups, and the multiple RO groups all include ROs existing in the uplink timeslot.

[0191] Alternatively, the RO types included in the RO group determined by the terminal are mapped to the same downlink reference signal, or may be mapped to different downlink reference signals. For example, the RO group determined by the terminal includes an RO existing in an uplink time slot and an RO existing in a time slot with flexible symbols, and both RO types are mapped to the same downlink reference signal, or the two RO types may also be mapped to different downlink reference signals. The downlink reference signal includes but is not limited to SSB, Channel State Information Reference Signal (CSI-RS), etc.

[0192] In the embodiment of the present application, in the enhanced duplex mode, it is also necessary to define a mapping method from a reference signal to a RO.

[0193] Optionally, in the enhanced duplex mode, the association of the reference signal to the RO satisfies at least one of the following:

[0194] Different RO types or RO resources are individually associated with the SSB;

[0195] At least two different RO types or RO resources are associated with the SSB together;

[0196] In the case where the RO and SSB time domains overlap, the RO and SSB are not associated.

[0197] For example, different RO types or RO resources are associated with SSBs separately, that is, different RO types or RO resources are associated with SSBs respectively, rather than being associated with them at the same time. At this time, one SSB may be associated with multiple types of ROs more quickly. For example, some ROs are in the subband and some ROs are in the normal uplink bandwidth. Then, the ROs that are associated with the same SSB in the subband and uplink bandwidth and are closer or more compact in time can be selected to determine the PRACH transmission resources. This is conducive to completing multiple PRACH transmissions or PRACH repetitions with low latency.

[0198] Alternatively, different RO types or RO resources are associated with the SSB together, that is, different RO types or RO resources can be associated with the SSB at the same time. In this case, the association with the SSB can be completed without distinguishing different types of ROs, which can reduce the association complexity of the SSB to RO.

[0199] In addition, if the RO overlaps with an SSB in the time domain, the RO is not associated with the SSB. For example, if an RO on a certain subband has an SSB on the same OFDM symbol, the RO can be considered invalid, and the RO is not associated with the SSB, which can reduce interference to the SSB.

[0200] In the embodiment of the present application, for the association between SSB and RO, various corresponding periods or windows need to be determined.

[0201] Optionally, in the case where the RO type or RO resource is associated with the SSB, for example, different RO types or RO resources are individually associated with the SSB, or different RO types or RO resources are associated with the SSB together, the method further includes:

[0202] The terminal determines a first time period or a first window, where the first window includes a determination window of a PRACH group, and the first time period includes at least one of the following:

[0203] The SSB to RO mapping cycle (SSB to RO mapping cycle);

[0204] The SSB to RO association period (SSB to RO association period);

[0205] The SSB to RO association pattern period (SSB to RO association pattern period).

[0206] Optionally, the terminal may determine the first time period or the first window by itself, or may determine it based on an instruction of a network side device. In the case of PRACH repetition, the terminal needs to determine a determination window of the PRACH group, that is, the first window.

[0207] In the embodiment of the present application, in the enhanced duplex mode, for the association of SSB to RO, the terminal can determine the mapping period of SSB to RO or the association period of SSB to RO or the association mode period of SSB to RO, so that the time information of the association of SSB to RO can be effectively determined, which helps the terminal to determine the random access channel timing to improve the transmission performance of the terminal. In addition, for the case of PRACH repetition, the terminal determines the determination window of the PRACH group, which helps the terminal determine at which time to perform PRACH transmission to improve the transmission performance of the terminal.

[0208] Optionally, the first time period or the first window is determined by at least one of the following:

[0209] Determine the first time period or the first window respectively corresponding to different RO types or RO resources;

[0210] Determining a common first time period or first window according to at least two different RO types or RO resources;

[0211] The period of the enhanced duplex mode is determined according to the period of the enhanced duplex mode.

[0212] For example, for different RO types or RO resources, their respective corresponding first time periods or first windows are determined respectively. Exemplarily, taking the first time period as an example, for a RO existing in an uplink time slot, the terminal determines its corresponding first time period (that is, the mapping period of SSB to the RO or the association period of SSB to the RO or the association mode period of SSB to the RO), for a RO existing in a time slot with flexible symbols, the terminal determines the first time period corresponding to the type of RO, etc. Too many examples are not given here, so that the terminal can flexibly determine its respective corresponding first time period or first window for different RO types or RO resources.

[0213] Alternatively, a common first time period or first window may be determined for different RO types or RO resources, for example, all RO types or RO resources may correspond to the same first time period or first window. Exemplarily, when the mapping (association) of SSB to RO is performed independently for each RO type, that is, when different RO types or RO resources are individually associated with SSB, the maximum value of the time period determined based on all RO types may be used as the first time period, that is, all RO types eventually correspond to the first time period. For another example, when the mapping (association) of SSB to RO is performed for all RO types together, that is, when different RO types or RO resources are associated with SSB together, all RO types or RO resources jointly determine a common time period or window, that is, the first time period or first window.

[0214] Alternatively, the first time period or the first window may also be determined according to the period of the enhanced duplex mode, for example, the first time period or the first window is smaller than the period of the enhanced duplex mode.

[0215] In an embodiment of the present application, in the enhanced duplex mode, for the association between SSB and RO, the mapping period of SSB to RO or the association period of SSB to RO or the association mode period of SSB to RO or the determination method of the determination window of the PRACH group is clarified, which helps to reduce the delay of terminal random access and improve the terminal transmission performance.

[0216] Please refer to Figure 3 , Figure 3 is a flow chart of another resource configuration method provided in an embodiment of the present application, and the method is applied to a network side device. Figure 3 As shown, the method comprises the following steps:

[0220] The starting frequency domain position of the subband;

[0240] The RO is a valid RO, and the RO can be used to implement SSB to RO mapping, but whether the RO is used for actual PRACH transmission depends on the first condition;

[0241] The RO is not a valid RO and is not used to implement SSB to RO mapping.

[0242] Optionally, the first condition includes at least one of the following:

[0243] Whether the time interval or frequency domain interval between the RO and the SSB is less than or equal to a preset value;

[0244] Whether SSB or other downlink common channels or signals are transmitted on the other bandwidth;

[0245] Whether the terminal receives SSB or other downlink common channels or signals on the other bandwidth.

[0246] Optionally, the method further comprises:

[0247] The network side device sends second configuration information to the terminal, where the second configuration information is used to configure at least one RO type, and the at least one RO type includes at least one of the following:
