Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a transmission processing method, a configuration method, a device, a terminal, and a network-side device. Background Art

[0002] Future mobile communication systems need to adapt to more diverse scenarios and service requirements, such as enhanced mobile broadband (eMBB), ultra-reliable and low-latency communications (URLLC), and massive machine type of communication (mMTC).

[0089] For the convenience of understanding, some contents related to the embodiments of the present application are described below:

[0090] I. Random access resource selection

[0091] The random access process can be a contention-based random access process or a non-contention-based random access process. The random access process can be a four-step random access process (also called Type-1 random access process) or a two-step random access process (also called Type-2 random access process).

[0092] In the competitive four-step random access procedure (RACH), a terminal (such as a User Equipment (UE)) first sends Msg1 to the network, which contains a preamble; after the network detects the preamble, it will send a Msg2 / Random Access Response (RAR) message, which contains the number of the preamble detected by the network and the uplink radio resources allocated to the UE to send Msg3; after the UE receives Msg2, it confirms that at least one of the preamble numbers carried in Msg2 is the same as the preamble number it sent, and then sends Msg3 containing contention resolution information according to the resources indicated by the RAR; after the network receives Msg3, it will send Msg4 containing contention resolution information; when the UE receives Msg4 and confirms that the contention resolution information is the same as what it sent in Msg3, the four-step random access is completed.

[0093] The network includes uplink grant (UL grant) information in the RAR to indicate the scheduling information of the MSG3 Physical Uplink Shared Channel (PUSCH), and also includes information such as the RACH preamble ID (RAPID), Temporary Cell Radio Network Temporary Identity (TC-RNTI), and Time Alignment (TA). If the network does not receive the MSG3 PUSCH, it can schedule the retransmission of the MSG3 PUSCH in the Physical Downlink Control Channel (PDCCH) scrambled with the TC-RNTI.

[0094] For the competitive random access process, different UEs randomly select preambles for transmission. In this way, different UEs may select the same preamble to send on the same time-frequency radio resource (also known as the random access occasion (RO)). This situation can be understood as a preamble collision among UEs. In this case, different UEs will receive the same RAR. Then, different UEs will perform the transmission of MSG3 PUSCH according to the scheduling information in the RAR UL grant. The network can only decode the PUSCH (including the contention resolution information) sent by one UE on a MSG3 PUSCH scheduling resource. Therefore, the network will include the contention resolution information received in MSG3 in MSG4. If the contention resolution information received by the UE in MSG4 matches the contention resolution information sent by the UE in MSG3 PUSCH, the UE considers the contention resolution successful. If not, it is considered that the contention resolution is unsuccessful.

[0095] If the contention resolution is unsuccessful, the UE re-selects the transmission resource of the physical random access channel (RACH) to perform the transmission of the physical random access channel (PRACH) and makes the next random access attempt.

[0096] In the two-step random access process (2-step RACH), the first step is for the UE to send MsgA to the network side. After receiving MsgA, the network side sends MsgB to the UE. If the UE does not receive MsgB within a certain period of time, the UE will accumulate the counter for counting the number of MsgA transmissions and re-send MsgA. If the counter for counting the number of MsgA transmissions reaches a certain threshold, the UE will switch from the 2-step random access process to the 4-step random access process. MsgA includes a MsgA preamble part and a MsgA PUSCH part. The preamble part is sent on the RO used for 2-step RACH, and the PUSCH part is sent on the MsgA PUSCH resource associated with the sent MsgA preamble and RO. The MsgA PUSCH resource is a set of PUSCH resources configured for each PRACH slot, including time-frequency resources and demodulation reference signal (DMRS) resources.

[0097] II. Selection of Random Access Resources and Mapping of Synchronization Signal and PBCH block (SSB) to RO

[0098] In New Radio (NR), a cell can configure multiple Frequency Division Multiplexing (FDM) Physical Random Access Channel (PRACH) transmission opportunities (also called PRACH Occasion) at a time domain position for transmitting PRACH. For simplicity, it is abbreviated as RO here. At a certain moment, the number of ROs that can be FDM can be: {1, 2, 4, 8}. At a certain moment, 8 RO resources are distributed on different frequencies.

[0099] The random access preamble can only be transmitted on the time domain resources (i.e., RO) configured by the parameter PRACH Configuration Index, and the random access preamble can only be transmitted on the frequency domain resources configured by the parameter prach-FDM. The PRACH frequency domain resource n RA ∈{0, 1,..., M - 1}, where M is equal to the higher layer parameter prach-FDM. At the initial access, the PRACH frequency domain resource n RA is numbered in ascending order starting from the RO with the lowest frequency in the initial active uplink bandwidth part, otherwise, the PRACH frequency domain resource is numbered in ascending order starting from the RO with the lowest frequency in the active uplink bandwidth part.

[0100] In NR, there is an association relationship between the RO and the actually transmitted SSB (SS / PBCH block, Synchronization Signal / Physical Broadcast Channel block, sometimes simply referred to as SS block, Synchronization Signal block). One SSB may be associated with multiple ROs, or multiple SSBs may be associated with 1 RO (in this case, different SSBs correspond to different Preamble codes). Usually, the base station can use different beams to transmit different SSBs, and the corresponding UE sends a 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 good signal according to the intensity of the received downlink beam / SSB, and sends Msg1. In this way, the network can determine the SSB selected by the UE according to 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.

[0101] III. PRACH Time-Domain Resource Location (Period, occasion, etc.)

[0102] The PRACH resource is a periodic resource. In the time domain, different PRACH Preamble formats have different durations. The time-domain location of the PRACH resource is defined by the PRACH configuration period, radio frame index, subframe / slot index, starting PRACH OFDM symbol index within the slot, and the number of time-domain ROs within the slot. Among them, the candidate values of the PRACH configuration period are {10, 20, 40, 80, 160} ms. Within each PRACH configuration period, the PRACH resource is only distributed in one valid radio frame (10 ms), and this valid radio frame contains one or more subframes / slots. There is only one starting PRACH OFDM symbol index within each subframe / slot, and there is one or more time-domain ROs within a slot. In the frequency domain, different PRACH Preamble formats and subcarrier spacings jointly determine the frequency-domain bandwidth occupied by the PRACH. For the long Preamble format with a length of 839, when the PRACH subcarrier spacing is 1.25 kHz, the frequency-domain bandwidth is 1.08 MHz (corresponding to 6 PRBs with a PUSCH subcarrier spacing of 15 kHz).

[0103] IV. SSB-RO Mapping Cycle

[0104] In NR, there is an association relationship between the RO and the actually transmitted SSB (SS / PBCH block, Synchronization Signal / Physical Broadcast Channel block, simply referred to as SSB). The RO is associated with the SSB in the order of frequency domain (from low frequency to high frequency) first and then time domain. One SSB may be associated with multiple consecutive ROs, or multiple SSBs may be associated with 1 RO (in this case, different SSBs correspond to different Preambles), which is configured by the network through the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB.

[0105] After all SSBs are associated with ROs in one round, it constitutes an SSB-RO mapping cycle.

[0106] V. Association period, also known as association cycle

[0107] The association period from an SSB to an RO may contain one or more SSB-RO mapping cycles.

[0108] The definition of the association cycle from an SSB to an RO is that at least one round of mapping from the SSB to the RO is completed within this cycle, so that each actually transmitted SSB is mapped to at least one RO. The association cycle of the SSB mapped to the RO must be an integer multiple of the PRACH configuration period, and the multiple is the minimum value among the values listed in Table 1 below, the mapping table between the PRACH configuration period and the SS / PBCH block to the PRACH occasion association period (Mapping between PRACH configuration period and SS / PBCH block to PRACH occasion association period). Among them, this association cycle is calculated starting from radio frame 0. Within one association cycle, after one round of mapping from the SSB to the RO is completed, the next round of mapping continues until the remaining ROs are not enough to complete one round of mapping from the SSB to the RO. If the remaining ROs are not enough to complete one round of mapping from the SSB to the RO, then these remaining ROs form an invalid RO set. All ROs within this invalid RO set cannot be associated with the SSB and cannot be used for PRACH transmission.

[0109] Table 1

[0110]

[0111] VI. Valid PRACH occasions

[0112] 1) For paired spectrum (Frequency Division Duplexing, FDD), all PRACH occasions are valid.

[0113] 2) For unpaired spectrum (Time Division Duplexing, TDD),

[0114] If the UE does not receive the time division duplex uplink-downlink common configuration (tdd-UL-DL-ConfigurationCommon), then in the current PRACH slot, if the PRACH occasion does not precede the SSB and is at least Ngap symbols apart from the nearest previous SSB, then the PRACH occasion is valid;

[0115] If the UE receives tdd-UL-DL-ConfigurationCommon, if: the PRACH occasion is in the UL symbols or in the current PRACH slot, the PRACH occasion does not precede the SSB, is at least Ngap symbols apart from the nearest previous SSB, and is at least Ngap symbols apart from the last previous DL symbol, then the PRACH occasion in the PRACH slot is considered valid.

[0116] VII. Association pattern period of SSB and RO

[0117] Since under some configuration conditions, the number of valid ROs included in the association period of SSB mapped to RO is variable, therefore, the NR protocol further defines the time-domain repetition period of the association period of SSB mapped to RO through the association pattern period. The maximum value of the association pattern period of SSB mapped to RO is 160 ms.

[0118] An association pattern period from an SSB to an RO may contain one or more SSB-RO association periods, and the mapping from the SSB to the RO is repeated with the association pattern period as the period.

[0119] VIII. Status of the Transmission Configuration Indicator (TCI) of the Control Resource Set (coreset)

[0120] 1) For a CORESET other than the CORESET with index 0,

[0121] if the UE has not been configured with TCI states by the TCI StatesPDCCH ToAddList and TCI StatesDDCCHToReleaseList of the CORESET, or has been configured with more than one TCI state initial configuration by the TCI-StatesPDCCCH ToAddList or TCI-StatesDCCH ToRelaseList of the CORESET, but has not received a MAC CE activation command for one of the TCI states, the UE assumes that the DM-RS antenna port associated with PDCCH reception is quasi-co-located with the SS / PBCH block identified by the UE during the initial access procedure;

[0122] if the UE has been configured with more than one TCI state by the TCI StatesPDCCH ToAddList and TCI StatesDDCCHToReleaseList of the CORESET as part of the current reconfiguration procedure with synchronization, but has not received a MAC CE activation command for one of the TCI states as described above, the UE assumes that the DM-RS antenna port associated with PDCCH reception is quasi-co-located with the SS / PBCH block or the CSI-RS resource identified by the UE during the random access procedure initiated by the synchronization reconfiguration procedure.

[0123] 2) For the CORESET with index 0, the UE assumes that the DM-RS antenna port used for PDCCH reception in the CORESET is quasi-co-located with the following:

[0124] one or more DL RSs configured by the TCI state, where the TCI state is indicated by the MAC CE activation command of the CORESET, if any, or

[0125] the SS / PBCH block identified by the UE during the most recent random access procedure that was not initiated by a PDCCH command triggering a non-competitive random access procedure, if no MAC CE activation command indicating the TCI state of the CORESET has been received after the most recent random access procedure.

[0126] For a CORESET other than the CORESET with index 0, if a single TCI state of the CORESET is provided to the UE, or if the UE receives a MAC CE activation command for one of the TCI states provided for the CORESET, the UE assumes that the DM-RS antenna port associated with PDCCH reception in the CORESET is quasi-co-located with one or more DL RSs configured by the TCI state. For the CORESET with index 0, the UE expects that the QCL TypeD of the CSI-RS in the TCI state indicated by the MAC CE activation command of the CORESET is provided by the SS / PBCH block.

[0127] If the UE receives a MAC CE activation command for one of the TCI states, the UE applies the activation command in the first time slot after the time slot where k is the time slot in which the UE will transmit a Physical Uplink Control Channel (PUCCH) with Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK) information for the PDSCH that provided the activation command, and μ is the SubCarrier Space (SCS) configuration for the PUCCH. The activated Band Width Part (BWP) is defined as the activated BWP in the time slot when the activation command is applied. For a subcarrier spacing of u, the number of slots contained in one subframe.

[0128] VIII. Subbands non-overlapping Full duplex

[0129] Subbands non-overlapping Full duplex can improve transmission latency and enhance coverage.

[0130] For a DL slot (configured by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated), the network configures a DL BWP for the UE; for a UL slot, the network configures a UL BWP for the UE.

[0131] For the full duplex scenario, there are the following cases:

[0132] For a DL slot (configured by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated), as Figure 2 shown,

[0133] Case 1: Configure the DL BWP as slot 1;

[0134] Case 2: Configure the DL BWP and the UL sub band as slot 2;

[0135] For a UL slot (configured by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated), as Figure 3 shown,

[0136] Case 3: Configure the UL BWP as slot 4;

[0137] Case 4: Configure the UL BWP and the DL sub band as slot 5.

[0138] For SubBand Full Duplex (SBFD) operation, an SBFD sub band consists of 1 RB or a continuous set of RBs with the same transmission direction.

[0139] The time domain units (such as slots or symbols) used by the gNB for SBFD operation can be referred to as SBFD time domain units (such as slots or symbols).

[0140] In one way, the base station and the UE can only transmit or receive at one moment.

[0141] In one way, the gNB is full duplex, the gNB can transmit and receive simultaneously, and the UE side can only adopt the half-duplex mode, that is, it can only transmit or receive at one moment.

[0142] In one way, the UE side is full duplex, and the gNB and the UE can transmit and receive simultaneously. For the full duplex of the UE side, a relatively large guard band (GB) may be required to suppress self-interference, such as greater than the GB of the base station's full duplex (FD) operation.

[0143] For a communication device, simultaneous UL reception and DL transmission will cause self-interference. To ensure the transmission in the interfered direction, the communication device needs to have the ability to cancel self-interference, such as reserving a guard band between the receiving frequency band and the transmitting frequency band, but this will reduce the throughput of the UE.

[0144] In the embodiments of the present application, a valid random access occasion means that both the frequency-domain resource and the time-domain resource of this random access occasion are valid.

[0145] In the embodiments of the present application, the units of time-domain units include but are not limited to time slots and symbols.

[0146] In the embodiments of the present application, a time-domain unit including an uplink sub-band (UL SB) can be an uplink time-domain unit, a downlink time-domain unit, or a flexible time-domain unit. Of course, the uplink time-domain unit, the downlink time-domain unit, and the flexible time-domain unit can also be configured with a downlink sub-band (DL SB). Among them, if the flexible time-domain unit is only configured with a downlink sub-band (DL SB), the resources available for UL transmission in this flexible time-domain unit can include the resources in this flexible time-domain unit except for the DL SB and the GB.

[0147] In the embodiments of the present application, an uplink time-domain unit without a configured sub-band is also called a UL only time-domain unit; a downlink time-domain unit without a configured sub-band is also called a DL only time-domain unit; a flexible time-domain unit without a configured sub-band is also called a flexible only time-domain unit.

[0148] For the sake of simplified description, the embodiments of the present application mainly describe the uplink sub-band (located in the downlink time unit, or the uplink time unit, or the flexible time unit) and the uplink time unit (without a configured sub-band). Other resource types and combinations are not excluded.

[0149] In the embodiments of the present application, the SSB to RO mapping can also refer to the association between a generalized downlink signal and an uplink signal / resource, such as the association between the SSB and small data transmission (SDT), the association between the channel state information reference signal (CSI-RS) and the RO, etc.

[0150] In the embodiments of the present application, a RACH Occasion (RO), which can also be understood as a PRACH Occasion, both refer to the time-frequency resources required to send a PRACH sequence. The random access process is the random access (RA).

[0151] In the embodiments of the present application, the SSB and the SS / PBCH block can be used interchangeably, and can also have other names, and can refer to any module containing at least part of the synchronization signal, broadcast signal, or other downlink broadcast signals.

[0152] In the embodiments of the present application, the PRACH resource may be the PRACH time-frequency resource and / or the PRACH sequence.

[0153] In the embodiments of the present application, the shared RO (shared RO) means that there is a PRACH sequence for a certain PRACH transmission and also a PRACH sequence for another PRACH transmission. The separate RO (Separate RO) or the separately configured RO (separately configured RO) means a PRACH occasion that is additionally configured only for different types of PRACH transmissions.

[0154] In the embodiments of the present application, the above RO types are any one of the following: the RO resource of the uplink sub-band, the RO resource of the uplink time domain unit, the RO resource of the flexible time domain unit, the RO resource across multiple resources. For example, the RO resource across multiple resources is the RO resource that simultaneously occupies the uplink sub-band and the uplink time domain unit. For simplicity of description, only the RO resources of the uplink sub-band and the RO resources of the uplink time domain unit are taken as examples.

[0155] In the embodiments of the present application, the following two full-duplex modes are defined for simplified description.

[0156] Network full-duplex mode: That is, the network side applies full-duplex and the terminal side applies half-duplex.

[0157] Terminal full-duplex mode: That is, the network side applies full-duplex and the terminal side applies full-duplex.

[0158] Among them, the half-duplex on the terminal side can be understood as that the terminal can only receive DL, or send UL signals or channels in one time unit (also known as the time domain unit). The full-duplex on the terminal side can be understood as that the terminal receives DL and sends UL signals or channels simultaneously in one time unit.

[0159] The network full-duplex mode can achieve the purposes of enhancing coverage, reducing transmission delay, and improving resource utilization efficiency. The terminal full-duplex mode can improve the DL (UL) throughput while obtaining the above gains.

[0160] Usually, a guard band needs to be reserved between UL transmission and DL transmission. For example, a guard band (GB) is reserved to achieve frequency isolation and reduce self-interference. Usually, the self-interference cancellation ability of the UE is weaker than that of the gNB side. For the simultaneous transceiver on the UE side, a larger GB needs to be reserved than that on the gNB side, that is, more reserved PRBs are required as the protection frequency band.

[0161] Such as Figure 4As shown in the figure, (a) is the sub-band and GB configuration of network-side full duplex, that is, the network configures the time-frequency resources of UL SB and DL SB (and / or GB). In UL SB, the network receives the UL channel or signal of the served UE. In DL SB, the network sends the DL channel or signal to the served UE. The DL transmission will generate self-interference to the UL reception.

[0162] As Figure 4 shown in the figure, (b) is the sub-band configuration of UE-side full duplex. The network configures the time-frequency resources of UL SB and DL SB (and / or GB) for the UE. The UL transmission of the UE will generate self-interference to the DL reception.

[0163] The capabilities of different UEs may be different, so the GBs that need to be reserved may also be different.

[0164] In the embodiments of this application, enhanced duplex is used, which can also be called enhanced duplex mode, XDD, enhanced full duplex, enhanced full duplex mode. The enhanced duplex can be expressed as: supporting an uplink sub-band within a downlink time unit, or supporting a downlink sub-band on an uplink time unit, or supporting at least one of an uplink sub-band or a downlink sub-band transmission on a flexible time unit.

[0165] Among them, the enhanced duplex can include network full duplex and terminal full duplex.

[0166] The network notifies the enhanced duplex pattern in System Information Block (SIB) 1 or Master Information Block (MIB), including at least one of the following: enhanced duplex configuration period, enhanced duplex mode period, UL-DL config common.

[0167] For example, as Figure 5 shown in the figure, UL-DL config common is DDDDU, and the period is 5 ms. That is, the 5 time-domain units in one period (5 ms) are successively a downlink time-domain unit, a downlink time-domain unit, a downlink time-domain unit, a downlink time-domain unit, and an uplink time-domain unit. The enhanced duplex configuration is 11100 00000, and the mode (enhanced duplex mode) is DUD, and the period is 10 ms. That is, the 10 time-domain units in one period (10 ms), the first 3 time-domain units are divided into three sub-bands according to the mode DUD. The enhanced duplex mode period is 10 ms (for different mode periods, the enhanced duplex mode can change, for example, the frequency-domain sub-bands are DUD, DU, UD...), as Figure 5Among them, in the two enhanced duplex mode periods, in the first enhanced duplex mode period, the mode is DUD, and in the second enhanced duplex mode period, the mode is DU.

[0168] The following will combine the accompanying drawings and elaborate on the transmission processing method, configuration method, device, terminal, and network-side device provided by the embodiments of the present application through some embodiments and their application scenarios.

[0169] As Figure 6 shown, a transmission processing method according to an embodiment of the present application includes:

[0170] Step 601, the terminal determines a valid random access opportunity, where the valid random access opportunity includes a random access opportunity within the uplink sub-band of the first time-domain unit, or a random access opportunity within the frequency domain of the second time-domain unit; where the second time-domain unit is an uplink time-domain unit without configured sub-bands or a flexible time-domain unit;

[0171] Step 602, the terminal performs transmission at the valid random access opportunity.

[0172] In this way, the terminal can determine the random access opportunity within the uplink sub-band of the first time-domain unit, or the random access opportunity within the frequency domain of the second time-domain unit as a valid random access opportunity, and thus perform transmission at the valid random access opportunity, avoiding the occurrence of self-interference and cross-link interference, improving system performance, and reducing access delay.

[0173] Among them, the first time-domain unit can be an uplink time-domain unit, a downlink time-domain unit, or a flexible time-domain unit. The second time-domain unit is a UL only time-domain unit or a flexible time-domain unit. Among them, for a flexible time-domain unit configured with only DL sub-bands, the effective RO is located in the resources other than the DL sub-band and the GB.

[0174] That is to say, in this embodiment, for frequency-domain resources, a valid RO means that the RO is located in

[0175] 1) UL SB (UL time-domain unit, or DL time-domain unit, or flexible time-domain unit);

[0176] 2) Any resource on the UL only time-domain unit;

[0177] 3) Resources on the flexible time-domain unit.

[0178] Among them, if the flexible time-domain unit is only configured with DL SB, the effective RO is located in the resources other than the DL SB and the GB of the flexible time-domain unit. Any resource on the UL only time-domain unit can include any resource on the flexible only time-domain unit.

[0179] Optionally, in this embodiment, before the terminal executes step 601, it can obtain the positions of one or more ROs. For example, the network side device configures an RO set, or multiple ROs are predefined. Further, the terminal can determine the valid ROs from the one or more ROs.

[0180] It should be noted that the method of the embodiment of the present application is preferably applied to the terminal in the SBFD communication scenario.

[0181] Optionally, in this embodiment, the terminal determines the valid random access opportunity, including:

[0182] The terminal obtains the rules configured or predefined by the network side device;

[0183] The terminal determines the valid random access opportunity based on the rules among the random access opportunities configured by the network side device;

[0184] Among them, the rules include one of the following:

[0185] The valid random access opportunity is located in the uplink sub-band of the first time domain unit; or

[0186] When the terminal is not configured with the first information, the valid random access opportunity is located in the uplink sub-band of the first time domain unit, and the valid random access opportunity does not precede the synchronization signal block SSB in the random access slot where it is located, and the interval from the first SSB is greater than or equal to the first value; when the terminal is configured with the first information, the valid random access opportunity is located in the uplink sub-band of the first time domain unit, and the valid random access opportunity does not precede the SSB in the random access slot where it is located, the interval from the first SSB is greater than or equal to the second value, and the interval from the third time domain unit is greater than or equal to the second value; where the first SSB is the SSB that is located before the valid random access opportunity and has the smallest interval from the valid random access opportunity; or;

[0187] The valid random access opportunity is located in the uplink sub-band of the first time domain unit, and the interval between the valid random access opportunity and the fourth time domain unit in the random access slot where it is located is greater than or equal to the third value;

[0188] The valid random access opportunity is located in the uplink sub-band of the first time domain unit, and the interval between the valid random access opportunity and the fifth time domain unit in the random access slot where it is located is greater than or equal to the fourth value.

[0189] Optionally, the third time domain unit is the downlink time domain unit that is located before the valid random access opportunity and has the smallest interval from the valid random access opportunity in the random access slot, and no sub-band is configured on the third time domain unit;

[0190] The fourth time domain unit is a downlink or uplink time domain unit on the random access time slot that is before the effective random access occasion and has the smallest interval from the effective random access occasion, and no sub-bands are configured on the fourth time domain unit;

[0191] The fifth time domain unit is a downlink or uplink time domain unit on the random access time slot that is after the effective random access occasion and has the smallest interval from the effective random access occasion, and no sub-bands are configured on the fifth time domain unit.

[0192] Optionally, the first information is a time division duplex uplink-downlink common configuration (tdd-UL-DL-ConfigurationCommon).

[0193] In addition, optionally, in this embodiment, when the terminal determines the effective random access occasion based on the rule among the random access occasions configured by the network side device, it includes:

[0194] When receiving the time division duplex uplink-downlink common configuration, the terminal determines that a random access occasion located within the uplink sub-band of the first time domain unit and having an interval greater than or equal to a third value from the fourth time domain unit on the random access time slot where it is located is the effective random access occasion.

[0195] That is to say, only when the terminal is configured with tdd-UL-DL-ConfigurationCommon, for the RO within the uplink sub-band of the first time domain unit, it will determine whether it is effective by whether its interval from the fourth time domain unit on the random access time slot where it is located is greater than or equal to the third value.

[0196] Optionally, the first value and the second value are equal to the interval N gap The value of the symbol. N gap is related to the subcarrier spacing. For example, when the subcarrier spacing is 1.25 kHz or 5 kHz, N gap is equal to 0; when the subcarrier spacing is 15 kHz or 30 kHz or 60 kHz or 120 kHz, N gap is equal to 2.

[0197] Of course, the first value and the second value can also take other values, which are configured or predefined by the network side device. Moreover, the first value and the second value can be the same or different.

[0198] Optionally, the third value and the fourth value can also be configured or predefined by the network side device to be the same or different values.

[0199] In addition, in this embodiment, the rule can be understood as the requirements that an effective RO needs to meet in the time domain.

[0200] Among them, Rule 1: The valid random access opportunity is located within the uplink sub-band of the first time-domain unit.

[0201] That is, for the RO resources of the UL SB of the first time-domain unit, all ROs are valid.

[0202] Rule 2: When the terminal is not configured with tdd-UL-DL-ConfigurationCommon, the valid random access opportunity is located within the uplink sub-band of the first time-domain unit, and the valid random access opportunity does not precede the synchronization signal block SSB in the random access slot where it is located, and the interval from the first SSB is greater than or equal to the first value; when the terminal is configured with tdd-UL-DL-ConfigurationCommon, the valid random access opportunity is located within the uplink sub-band of the first time-domain unit, and the valid random access opportunity does not precede the SSB in the random access slot where it is located, the interval from the first SSB is greater than or equal to the second value, and the interval from the third time-domain unit is greater than or equal to the second value.

[0203] Here, for an RO resource, the RO does not precede the SSB, which can be understood as, in the slot where an RO is located, that is, the RO is located in the current PRACH slot, the RO is after the last SSB in the SSBs of this slot; the first SSB is the SSB closest to the RO in the SSBs of this slot; the third time-domain unit is the DL only symbol closest to the RO and before the RO in the current PRACH slot.

[0204] Specifically, both the first value and the second value can be Ngap, with the unit of symbol. Therefore, for the RO resources of the UL SB of the first time-domain unit,

[0205] If the UE does not receive tdd-UL-DL-ConfigurationCommon, then in the current PRACH slot, the RO does not precede the SSB, and the interval from the closest SSB in front is at least Ngap symbols, and the RO is considered valid;

[0206] If the UE receives tdd-UL-DL-ConfigurationCommon, then in the current PRACH slot, the RO does not precede the SSB, and the interval from the closest SSB in front is at least Ngap symbols, and the interval from the last DL only symbol in front is at least Ngap symbols, and the RO is considered valid.

[0207] Ngap can be predefined or configured by the network. For example, Ngap is greater than or equal to 0.

[0208] Rule 3: The valid random access opportunity is located within the uplink sub-band of the first time domain unit, and the interval between the valid random access opportunity and the fourth time domain unit in the random access slot where it is located is greater than or equal to the third value;

[0209] The valid random access opportunity is located within the uplink sub-band of the first time domain unit, and the interval between the valid random access opportunity and the fifth time domain unit in the random access slot where it is located is greater than or equal to the fourth value.

[0210] Here, for an RO resource, the fourth time domain unit is the DL only symbol or UL only symbol that is closest to the RO and is located before the RO in the current PRACH slot; the fifth time domain unit is the DL only symbol or UL only symbol that is closest to the RO and is located after the RO in the current PRACH slot.

[0211] Specifically, the third value and the fourth value can be the same or different, and the unit is a symbol. For example, the third value is X1 and the fourth value is X2. Therefore, for the RO in the UL SB of the first time domain unit,

[0212] If the UE does not receive tdd-UL-DL-ConfigurationCommon, or if the UE receives tdd-UL-DL-ConfigurationCommon, then in the slot where an RO is located, that is, the current PRACH slot, if the RO is at least X1 symbols away from the nearest DL only symbol or UL only symbol in front of it, the RO is considered valid;

[0213] In the current PRACH slot, if the RO is at least X2 symbols away from the nearest DL only symbol or UL only symbol behind it, the RO is considered valid.

[0214] For example, assume that the terminal is not configured with the time division multiplexing uplink and downlink common configuration. As Figure 7 shown, a random access slot includes a DL only time domain unit, a DL time domain unit, and a UL only time domain unit. RO1 and RO2 are located within the UL SB of the DL time domain unit, RO3 and RO4 are located within the UL only time domain unit, SSB1 is located within the DL only time domain unit, and SSB2 is located within the DL SB of the DL time domain unit. RO1 and RO2 are associated with SSB1, and RO3 and RO4 are associated with SSB2.

[0215] Therefore, since RO1 is located within the UL SB of the DL time domain unit, behind SSB2 in the random access time slot where it is located, and the interval from SSB2 is equal to Ngap symbols, RO1 satisfies Rule 2 and is a valid RO. Similarly, RO2 also satisfies Rule 2 and is a valid RO. Since RO3 and RO4 are located within the UL only time domain unit, RO3 and RO4 are valid ROs.

[0216] Assume that the terminal is configured with a time division multiplexing uplink-downlink common configuration. Similarly, as Figure 7 shown, a random access time slot includes a DL only time domain unit, a DL time domain unit, and a UL only time domain unit. RO1 and RO2 are located within the UL SB of the DL time domain unit, RO3 and RO4 are located within the UL only time domain unit, SSB1 is located within the DL only time domain unit, and SSB2 is located within the DL SB of the DL time domain unit. RO1 and RO2 are associated with SSB1, and RO3 and RO4 are associated with SSB2.

[0217] Therefore, since RO1 is located within the UL SB of the DL time domain unit, behind SSB2 in the random access time slot where it is located, and the interval from SSB2 is equal to Ngap symbols, and the interval from the DL only time domain unit is greater than Ngap symbols, RO1 satisfies Rule 2 and is a valid RO. Similarly, RO2 satisfies Rule 2 and is a valid RO. Since RO3 and RO4 are located within the UL only time domain unit, RO3 and RO4 are valid ROs.

[0218] Optionally, the above rules for determining the time domain validity of an RO can be extended to consider the case of whether an RO overlaps with an SSB.

[0219] Rule 2 can be extended as follows:

[0220] If the UE does not receive tdd-UL-DL-ConfigurationCommon, then in the current PRACH slot, except for the ROs that overlap with the SSB, the ROs do not precede the SSB and are at least Ngap symbols apart from the nearest previous SSB, and the RO is considered valid;

[0221] If the UE receives tdd-UL-DL-ConfigurationCommon, then in the current PRACH slot, except for the ROs that overlap with the SSB, the ROs do not precede the SSB and are at least Ngap symbols apart from the nearest previous SSB, and are at least Ngap symbols apart from the last DL only symbol in the front, and the RO is considered valid.

[0222] The UE does not expect an SSB to be mapped to an RO with time domain overlap or a previous RO.

[0223] In the above content, it is known that the terminal determines a valid RO among one or more ROs obtained. Specifically, the one or more ROs may be configured by a network-side device. Therefore, in an embodiment of the present application, optionally, the method further includes:

[0224] The terminal receives configuration information of a random access opportunity sent by the network-side device;

[0225] Among them, in the configuration information, the first configuration and the second configuration are the same configuration, or the first configuration and the second configuration are independent configurations;

[0226] The first configuration is a configuration of a random access opportunity within the uplink sub-band of the first time-domain unit;

[0227] The second configuration is a configuration of a random access opportunity within the frequency domain of the second time-domain unit.

[0228] That is, the network-side device can uniformly configure the ROs in the first time-domain unit and the ROs in the second time-domain unit; or can independently configure the ROs in the first time-domain unit and the ROs in the second time-domain unit. For example, when using a unified configuration, the frequency-domain resources occupied by the ROs in the first time-domain unit and the ROs in the second time-domain unit are the same; when using an independent configuration, the frequency-domain resources occupied by the ROs in the first time-domain unit and the ROs in the second time-domain unit are different.

[0229] Specifically, as Figure 8 shown, the ROs in the UL sub-band and the ROs in the UL only time-domain unit adopt the same RO configuration, including RO1-RO6, that is, the same frequency-domain resources are used. However, since RO1-RO3 in the DL time-domain unit are in the GB and UL SB, RO1-RO3 (the ROs circled by the dotted line) in the DL time-domain unit are unavailable. Therefore, the ROs in the UL SB of the DL time-domain unit are obtained by removing the ROs located in the unavailable frequency-domain resources from the ROs in the UL only time-domain unit. Therefore, for the ROs in the DL time-domain unit, the terminal determines valid ROs among RO4-RO6, and at this time, RO4-RO6 need to be renumbered as RO1-RO3.

[0230] Specifically, as Figure 9 shown, the ROs in the UL sub-band and the ROs in the UL only time-domain unit adopt independent configurations. RO1 and RO2 are in the UL SB, and their frequency-domain positions are different from the frequency-domain resources of RO1 and RO2 in the UL only time-domain unit.

[0231] In addition, in this embodiment, the terminal performs transmission at the valid random access opportunity, including:

[0232] The terminal receives the spatial domain parameters sent by the network-side device;

[0233] The terminal sends at least one of the following on the valid random access occasion according to the spatial domain parameters:

[0234] The first message in the two-step random access procedure;

[0235] The first message in the four-step random access procedure;

[0236] The third message in the four-step random access procedure;

[0237] Configuration grant based on small data transmission;

[0238] The physical uplink control channel PUCCH for confirming the fourth message in the four-step random access procedure;

[0239] Random access success response message.

[0240] That is, the terminal can send at least one of the first message (MSG A) in the two-step random access procedure, the first message (MSG1) in the four-step random access procedure, the third message (MSG3) in the four-step random access procedure, the configuration grant based on small data transmission (CG based SDT), the PUCCH (CommonPUCCH to ackowledge for MSG4) for confirming the fourth message in the four-step random access procedure, and the random access success response message (successRAR) on the valid RO. Of course, the transmission on the valid RO is not limited to the above content and may also include MSG5. The spatial domain parameters adopted by the valid RO are indicated by the network-side device.

[0241] Optionally, the spatial domain parameters include the state of the Transmission Configuration Indicator (TCI) or the Spatial Relation Information (SRI).

[0242] Specifically, the network-side device indicates the spatial domain parameters in semi-static signaling (such as SIB messages or RRC release messages) or dynamic signaling.

[0243] Optionally, the terminal uses the spatial domain parameters for transmission, and the spatial domain parameters are applied to the RO located in the UL SB, such as the valid RO.

[0244] Optionally, the terminal uses the spatial domain parameters for transmission, and the spatial domain parameters are applied to the RO located in the UL SB and overlapping with the SSB or the common control channel (such as the PDCCH or PDSCH carrying system information), such as the valid RO.

[0245] Optionally, the terminal performs transmission using the airspace parameters, and the airspace parameters are applied to ROs located in the UL SB and ROs in the UL only time domain unit, such as valid ROs.

[0246] Optionally, the terminal performs transmission using the airspace parameters, and the airspace parameters are applied to ROs located in the UL SB and overlapping with the SSB or the common control channel, such as valid ROs, and ROs located in the UL only time domain unit and overlapping with the SSB or the common control channel, such as valid ROs.

[0247] Optionally, the airspace parameters sent by the network side device include at least one of the following:

[0248] Airspace parameters corresponding to different SSBs or common control channels;

[0249] Airspace parameters corresponding to different uplink transmissions, where the uplink transmissions are associated with the SSB.

[0250] That is to say, the network side device can configure corresponding airspace parameters for different SSBs or common control channels; the network side device can also configure corresponding airspace parameters for different uplink transmissions, such as ROs, especially valid ROs.

[0251] Among them, the airspace parameters corresponding to the different SSBs include at least one of the following:

[0252] Airspace parameters for the uplink transmission associated with the SSB;

[0253] Airspace parameters for the downlink transmission corresponding to the uplink transmission associated with the SSB.

[0254] In this way, if the network side device configures airspace parameters corresponding to different SSBs or common control channels, and the airspace parameters are used for the uplink transmission associated with the SSB, then for the RO resources located in the UL SB or the UL only time domain unit, especially the valid RO resources, the airspace parameters corresponding to the SSB associated with it can be used for transmission; or, in the case where the RO overlaps with the SSB or the common control channel, the airspace parameters corresponding to the SSB associated with it are used for transmission.

[0255] If the network - side device configures spatial domain parameters corresponding to different SSBs or common control channels, and the spatial domain parameters are used for the downlink transmission corresponding to the uplink transmission associated with the SSB, then for the RO, especially the valid RO, when sending the downlink transmission corresponding to the RO, the spatial domain parameters of the SSB associated with it configured by the network - side device can be adopted. Here, the downlink transmission corresponding to the RO can be understood as that the downlink transmission sends the relevant information of the RO. For example, when the RO sends MSG1, the downlink transmission sends MSG2 corresponding to MSG1. At this time, the downlink transmission corresponding to the uplink transmission associated with the SSB can be understood as the downlink transmission associated with the SSB.

[0256] Among them, when the network - side device sends spatial domain parameters corresponding to different uplink transmissions, the spatial domain parameters are used for the terminal to receive the downlink transmission, so as to determine the spatial domain parameters adopted by the downlink transmission when the downlink transmission overlaps with the uplink transmission.

[0257] Among them, the downlink transmission can be understood as a coreset, or the PDCCH or PDSCH of the coreset.

[0258] The terminal determines whether to adopt the spatial domain parameters configured by the network according to the overlapping situation between the UL transmission and the DL transmission.

[0259] Optionally, the terminal receives using the spatial domain parameters, and the spatial domain parameters are applied to the PDCCH or PDSCH located in the DL SB.

[0260] Optionally, the terminal receives using the spatial domain parameters, and the spatial domain parameters are applied to the PDCCH or PDSCH located in the DL SB and overlapping with the RO (such as the valid RO).

[0261] Optionally, the terminal receives using the spatial domain parameters, and the spatial domain parameters are applied to the PDCCH or PDSCH located in the DL SB and the PDCCH or PDSCH located in the DL - only time domain unit.

[0262] Optionally, the terminal receives using the spatial domain parameters, and the spatial domain parameters are applied to the PDCCH or PDSCH located in the DL SB and overlapping with the RO (such as the valid RO), and the PDCCH or PDSCH located in the DL - only time domain unit and overlapping with the RO (such as the valid RO).

[0263] In this embodiment, the PDCCH carries MSG2, MSGB or MSG4, and the PDSCH carries MSG2, MSGB or MSG4.

[0264] Optionally, the network - side device can configure a set of spatial domain parameters for the UE to adopt the corresponding spatial domain parameters when the uplink transmission (such as the valid RO) overlaps with different SSBs or common control channels in time domain.

[0265] For example, the spatialRelationInfo corresponding to each SSB index is configured for the corresponding UL transmission, as shown in Table 2 below.

[0266] Table 2

[0267]

[0268] Among them, spatialRelationInfo k1, k2,... kn are respectively quasi-orthogonal to the spatial directions of SSB index i+1, i+2,... i+n, thereby reducing self-interference and CLI.

[0269] For example, for a terminal, when the MSG 1 information transmission overlaps with the SSB index i+1 in the time domain, spatialRelationInfo k1 is used; when the MSG3 transmission (i.e., transmitting the PUSCH carrying MSG3) overlaps with the SSB index i+2 in the time domain, spatialRelationInfo k2 is used; when the CG based SDT transmission (i.e., transmitting the PUSCH carrying small data) overlaps with the SSB index i+n in the time domain, spatialRelationInfo kn is used. And so on.

[0270] Optionally, the network can configure a set of spatial parameters for the UE to adopt corresponding spatial parameters (TCI state) when the downlink transmission overlaps with the uplink transmission (such as RO) associated with different SSBs or the common control channel in the time domain.

[0271] For example, the TCI state corresponding to each SSB index is configured for the corresponding DL transmission, as shown in Table 3 below.

[0272] Table 3

[0273]

[0274] Among them, TCI state j1, j2... jn are quasi-orthogonal to the spatial directions of the UL transmission associated with SSB index i+3, i+4,... i+n-2, thereby reducing self-interference and CLI.

[0275] For example, for a terminal, when the UL transmission time domain associated with the PDCCH / PDSCH of MSG 2 overlaps with the UL transmission associated with SSB index i+3, the UL transmission associated with SSB index i+3 uses TCI state i+3, then the reception of MSG 2 uses TCI state j1; when the PDCCH of MSG 4 overlaps with the UL transmission time domain associated with SSB index i+4, the UL transmission associated with SSB index i+4 uses TCI state i+4, then the PDCCH of MSG 4 uses TCI state j2; when the reception of MSG 4 PDSCH overlaps with the UL transmission time domain associated with SSB index i+n, if the UL transmission associated with SSB index i+4 uses TCI state i+n-2, then the MSG 4 PDSCH uses TCI state jn. And so on.

[0276] Optionally, in this embodiment, the network side device only configures the spatial domain parameters of the UL transmission located in the UL SB, or only configures the spatial domain parameters of the DL reception located in the DL SB, or simultaneously configures the spatial domain parameters of the UL transmission located in the UL SB and the spatial domain parameters of the DL reception located in the DL SB.

[0277] When only the spatial domain parameters of the UL transmission located in the UL SB are configured, or only the spatial domain parameters of the DL reception located in the DL SB are configured, the purpose of reducing SI and CLI can be achieved.

[0278] When the spatial domain parameters of the UL transmission located in the UL SB and the spatial domain parameters of the DL reception located in the DL SB are simultaneously configured, that is, the network configures both the spatial domain parameters of the UL transmission within the UL SB and the spatial domain parameters of the DL within the DL SB, then these two spatial domain parameters should have strong orthogonality or a weak QCL relationship to ensure smaller SI and CLI. As shown in Table 4 below,

[0279] Table 4

[0280]

[0281] Optionally, the network side device can configure {UL spatial domain parameters, DL spatial domain parameters} to represent the association relationship between UL transmission and DL reception. For example, as shown in Table 5 below,

[0282] Table 5

[0283] SSB index {UL airspace parameters, DL airspace parameters}, SSB index i + 1 {k1, j1} SSB index i + 2 {k2, j2} … SSB index i + n {kn, jn}

[0284] UL spatial domain parameters, i.e., the spatial domain parameters for the uplink transmission associated with this SSB, can be the spatial domain parameters used for transmitting MSG 1 / MSG A / MSG3 / CG based SDT / Common PUCCH to acknowledge for MSG4 / successRAR / MSG 5 PUSCH. In one way, they can be the spatial domain parameters used for the RO or valid RO associated with this SSB.

[0285] DL spatial domain parameters, i.e., the spatial domain parameters for the downlink transmission corresponding to the uplink transmission associated with this SSB, can be the spatial domain parameters used for the PDCCH receiving MSG2 / MSGB / MSG 4, or the PDSCH of MSG2 / MSGB / MSG 4.

[0286] The spatial domain parameters kn and jn can be different from the spatial domain parameters characterized by the SSB index i+n, so as to achieve the purpose of suppressing SI and CLI.

[0287] For example, as Figure 10 shown, if the network side device configures the {UL spatial domain parameters, DL spatial domain parameters} of the SSB index i+3, the terminal transmits the RO i+3 (the time-frequency resources of the UE preamble code are within this RO) located in the UL SB associated with the SSB index i+3, and uses the UL spatial domain parameter (SRI k3) corresponding to the configured SSB index i+3; the terminal receives the coreset i+3 located in the DL SB corresponding to the RO i+3, and uses the DL spatial domain parameter (TCI state j3) corresponding to the configured SSB index i+3. Among them, the spatial domain parameters for transmitting the RO i+3 should be quasi-orthogonal to the spatial domain parameters of the coreset i+2, and the spatial domain parameters for receiving the coreset i+3 should be quasi-orthogonal to the spatial domain parameters of the RO i+4, so as to ensure lower SI or CLI.

[0288] Next, the use of the spatial domain parameters in the embodiments of this application will be described in combination with specific scenarios:

[0289] Example 1, as Figure 11 shown, for the valid RO i+1, RO i+2, RO i+1 is associated with SSB i+1, RO i+2 is associated with SSB i+2, RO i+1 overlaps with SSB i+3 in time domain, and RO i+2 overlaps with SSB i+4 in time domain.

[0290] The downlink transmission of network-side SSB i+3 will cause self-interference to the uplink receiving UE when it transmits a preamble in RO i+1. At the same time, the UE transmitting a preamble in RO i+1 will cause CLI to other UEs receiving SSB i+3. Therefore, the network can indicate a spatial domain parameter (SRI k1) to the UE that uses RO i+1 to transmit a preamble, and this spatial domain parameter is (quasi-)orthogonal to SSB i+3, thereby reducing self-interference and CLI.

[0291] Here, the SSB can represent a DL spatial domain parameter, such as TCI state i+1. The configured UL spatial domain parameter SRIk1 can have a different direction from that of TCI state i+1, thereby achieving the suppression of spatial domain self-interference and CLI.

[0292] It should be noted that if the TCI state i+1 represented by SSB i+1 has good quasi-orthogonality with the TCI state i+3 represented by SSB i+3, then the configured UL spatial domain parameter can be equal to the spatial domain parameter represented by SSB i+1.

[0293] Among them, the UL Tx Spatial domain filter is the same as the DL TCI state (it can be understood that the UL spatial domain parameter is the same as the DL spatial domain parameter), which means that the UE receives the signal or channel sent by the base station and sends the UL signal or channel to the base station in the opposite direction.

[0294] If the RO i+1 associated with SSB i+1 is located in the UL only time domain unit, then the beam used by the UE to transmit a preamble in RO i+1 can be based on implementation (determined by the UE itself), or can be specified by the protocol or network configuration, such as the TCI state i+1 or the spatial domain parameter k1 of SSB i+1.

[0295] Example 2, as Figure 12 shown, the downlink transmission of the network in coreset i+1 (associated with SSB i+1) will cause self-interference to the uplink receiving UE when it transmits a preamble in RO i+3 (associated with SSB i+3). At the same time, the UE transmitting a preamble in RO i+3 will cause CLI to other UEs receiving the PDCCH of coreset i+1. Therefore, the network can indicate a spatial domain parameter (TCI state j1) to the UE that uses coreset i+1 to receive the PDCCH, and this spatial domain parameter is (quasi-)orthogonal to the spatial domain parameter used by RO i+3 (associated with SSB i+3) to transmit a preamble, thereby reducing self-interference and CLI.

[0296] The coreset i+1 associated with SSB i+1 can use the same TCI state i+1 as SSB i+1. The configured DL spatial domain parameter TCI state j1 can have a different direction from that of TCI state i+1, so as to achieve the suppression of spatial self-interference and CLI.

[0297] It should be noted that if the TCI state i+1 represented by SSB i+1 has good quasi-orthogonality with the spatial domain parameter of the RO associated with SSB i+3 (represented as the same Tx Spatial domain filter as TCI state i+3), then the spatial domain parameter TCI state j1 can adopt the same SSB i+1 spatial domain parameter.

[0298] Optionally, if the coreset i+1 associated with SSB i+1 is located in the DL only time domain unit, then the TCI state (beam direction) used by the UE to receive the PDCCH in the coreset i+1 and the PDSCH scheduled by the PDSCH can be based on the implementation (the UE itself determines the beam to be used), or can be specified by the protocol or network configuration, such as the TCI state i+1 or TCI stae j1 of SSB i+1.

[0299] In the embodiments of the present application, for a time window (mapping cycle, association period, association pattern period), the order of the mapping from SSB to RO can be configured by the network or predefined. For example, the mapping of SS / PBCH block indexes to valid ROs can be in the following order:

[0300] 1 The preambles in each valid RO increase in the order of the preamble index;

[0301] 2 When RACH FDM is configured (i.e., multiple valid ROs in the frequency domain), it increases according to the frequency domain index;

[0302] 3 When multiple valid ROs are configured within a PRACH time slot, it increases according to the index within the PRACH time slot;

[0303] 4 When multiple PRACH time slots are configured, it increases according to the PRACH time slot index.

[0304] In the embodiments of the present application, within a mapping cycle, association period, association pattern period, the mapping from SSB to RO is determined according to the uplink and downlink configuration, enhanced duplex configuration, and the valid ROs in the UL SB and UL time domain unit determined by the enhanced duplex mode period.

[0305] Among them, the RO located in the UL SB and the RO in the UL only time domain unit are configured independently.

[0306] Optionally, the mapping from SSB to RO includes:

[0307] All SSBs are mapped to two types of ROs;

[0308] All SSBs are mapped to the RO located in the UL SB;

[0309] All SSBs are mapped to the RO located in the UL time domain unit.

[0310] For example, as Figure 13 shown, SSB1 is mapped to RO 1-1 located in the UL SB (UL SB in the UL symbol), and RO 1-2 located in the UL time domain unit (UL only symbol); SSB2 is mapped to RO2-1 located in the UL SB (UL SB in the UL time domain unit), and RO 2-2 located in the UL time domain unit (UL only symbol).

[0311] Among them, a PRACH configuration includes the RO of the UL SB and the RO of the UL time domain unit (without SB configured). An SSB is mapped to at least one of the RO of the UL SB and the RO of the UL time domain unit.

[0312] Optionally, at least all SSBs are supported to be mapped to the ROs of all UL time domain units.

[0313] In the embodiments of the present application, the mapping from SSB to RO can be divided into more types.

[0314] For networks and terminals supporting SBFD, there are usually 4 types of time domain units (symbols or slots), including: DL time domain unit (without SB configured), DL time domain unit configured with UL SB, UL time domain unit configured with DL SB, UL time domain unit (without SB configured).

[0315] As Figure 14 shown, for a configured RO resource (set) (PRACH occasions Physical random-access channel occasions), there may be 2 types of configuration situations, that is

[0316] Situation 1: The RO resource (set) is configured in a UL sub-band (which can be in a UL symbol, can be in a DL or flexible symbol), such as type A;

[0317] Situation 2: The RO resource (set) is configured in a UL time domain unit (without DL sub-band configured), such as Type B.

[0318] Furthermore, the configured RO resource(s) can be further divided according to whether it is time-domain overlapped with the SSB:

[0319] 1) Configured RO resource(s) / Type 1: The RO resource(s) is configured in the UL SB of a DL symbol where there is an SSB or a common DL channel, i.e., time-domain overlapped with the SSB or the common DL channel. At this time, the uplink transmission of one UE will interfere with the reception of the SSB of other UEs, i.e., cross-link interference. If the UE uses this SSB for measurement or decodes the common DL channel, self-interference will also be received.

[0320] 2) Configured RO resource(s) / Type 2: The RO resource(s) is configured in the UL SB of a DL symbol where there is no SSB or common DL channel, i.e., not time-domain overlapped with the SSB / common DL channel. At this time, the uplink transmission of one UE will interfere with the reception of the DL channel or signal of other UEs, i.e., PDCCH, PDSCH, CSI-RS, etc.

[0321] 3) Configured RO resource(s) / Type 3: The RO resource(s) is configured in the UL SB of a UL symbol, and the interference situation is similar to that of type 2.

[0322] 4) Configured RO resource(s) / Type 4: The RO resource(s) is configured in a UL symbol, and there is no cross-link interference at this time.

[0323] If the SS-RSRP of a certain SSB is greater than rsrp-ThresholdSSB, then select the SSB with SS-RSRP greater than rsrp-ThresholdSSB, otherwise select any SSB (the SS-RSRP of multiple SSBs is greater than rsrp-ThresholdSSB).

[0324] When selecting CSI-RS, the CSI-RSRP of the CSI-RS will be compared with the parameter rsrp-ThresholdSSB. If the CSI-RSRP of a certain CSI-RS is greater than rsrp-ThresholdCSI-RS, then select the CSI-RS with CSI-RSRP greater than rsrp-ThresholdCSI-RS.

[0325] Regarding whether a flexible time-domain unit is an effective resource for UL transmission, it can be based on the following rules:

[0326] (1) The flexible time-domain unit with neither UL nor DL direction configured;

[0327] The network can configure that this time-domain unit is an effective resource for UL transmission (such as RO).

[0328] (2) Configure flexible time domain units for UL SB;

[0329] The network can configure that the UL SB of this time domain unit is a resource for valid UL transmissions (such as RO).

[0330] (3) Configure flexible time domain units for DL SB;

[0331] The network can configure that the resources other than the DL SB and GB of this time domain unit are resources for valid UL transmissions (such as RO).

[0332] UL transmissions (such as RO) that overlap with GB in the frequency domain are invalid resources.

[0333] Optionally, the RO type classification can be based on the preamble format configured within the RO (such as preamble formats of different lengths). One RO resource can be associated with one preamble format. The RO can occupy at least one symbol or slot. One SSB can be associated with at least one type of RO, and different ROs can contain different preamble formats.

[0334] A method for selecting different RO types can be based on the threshold of the received signal strength configured by the network. For example, the network configures two thresholds, threshold A and threshold B, for each SSB.

[0335] For example, the UE first measures the RSRP X of the SSB. If the measured RSRP X of an SSB is greater than or equal to threshold A, the UE selects the RO type A associated with the SSB for random access. This RO type can be associated with a short preamble format. If the measured RSRP X of an SSB satisfies threshold B <= x < threshold A, the UE selects the RO type B associated with the SSB. This RO type is associated with a long preamble format.

[0336] In addition, the network can configure or predefine a rule. If an SSB is only configured with one associated RO type, then the UE can select the SSB based on the RO type. For example, SSB i is only configured with the RO type associated with the short preamble format. The UE measures the RSRP X of SSB i as threshold B <= X < threshold A, and the UE has no available long preamble format. Then the UE does not camp on this SSB. The UE selects other SSBs to apply the above rule, so that the UE can obtain better coverage performance by using the long preamble format.

[0337] The method of the embodiment of the present application can be used for SDT and SRS transmission before random access, which is not limited here.

[0338] In summary, the method of the embodiment of the present application reduces self-interference and cross-link interference, improves resource utilization rate, reduces access delay, and improves coverage.

[0339] As Figure 15 shown, a transmission processing method of the embodiment of the present application includes:

[0340] Step 1501, a network device receives a transmission from a terminal at a valid random access opportunity; the valid random access opportunity includes a random access opportunity within an uplink sub-band of a first time domain unit, or a random access opportunity within a frequency domain of a second time domain unit;

[0341] Wherein, the second time domain unit is an uplink time domain unit without configured sub-bands or a flexible time domain unit.

[0342] Optionally, the valid random access opportunity is a random access opportunity that satisfies a specific rule;

[0343] Wherein, the rule includes one of the following:

[0344] The valid random access opportunity is within the uplink sub-band of the first time domain unit; or

[0345] When the first information is not configured for the terminal, the valid random access opportunity is within the uplink sub-band of the first time domain unit, and the valid random access opportunity does not precede the synchronization signal block SSB in the random access slot where it is located, and the interval from the first SSB is greater than or equal to a first value; when the first information is configured for the terminal, the valid random access opportunity is within the uplink sub-band of the first time domain unit, and the valid random access opportunity does not precede the SSB in the random access slot where it is located, and the interval from the first SSB is greater than or equal to a second value, and the interval from the third time domain unit is greater than or equal to a second value; wherein, the first SSB is the SSB located before the valid random access opportunity and having the smallest interval from the valid random access opportunity; or;

[0346] The valid random access opportunity is within the uplink sub-band of the first time domain unit, and the interval between the valid random access opportunity and the fourth time domain unit in the random access slot where it is located is greater than or equal to a third value;

[0347] The valid random access opportunity is within the uplink sub-band of the first time domain unit, and the interval between the valid random access opportunity and the fifth time domain unit in the random access slot where it is located is greater than or equal to a fourth value.

[0348] Optionally, the third time domain unit is the downlink time domain unit on the random access time slot that is located before the valid random access opportunity and has the smallest interval from the valid random access opportunity, and no subbands are configured on the third time domain unit;

[0349] The fourth time domain unit is the downlink or uplink time domain unit on the random access time slot that is located before the valid random access opportunity and has the smallest interval from the valid random access opportunity, and no subbands are configured on the fourth time domain unit;

[0350] The fifth time domain unit is the downlink or uplink time domain unit on the random access time slot that is located after the valid random access opportunity and has the smallest interval from the valid random access opportunity, and no subbands are configured on the fifth time domain unit.

[0351] Optionally, the first information is a time division multiplexing uplink and downlink common configuration.

[0352] Optionally, the first value and the second value are equal to the value of interval N gap symbols.

[0353] Optionally, the method further includes:

[0354] The network side device sends configuration information of the random access opportunity;

[0355] Among them, in the configuration information, the first configuration and the second configuration are the same configuration, or the first configuration and the second configuration are independent configurations;

[0356] The first configuration is the configuration of the random access opportunity within the uplink subband of the first time domain unit;

[0357] The second configuration is the configuration of the random access opportunity within the frequency domain of the second time domain unit.

[0358] Optionally, the method further includes:

[0359] The network side device sends spatial domain parameters;

[0360] The network device receives the transmission of the terminal at the valid random access opportunity, including:

[0361] The network device receives at least one of the following sent by the terminal according to the spatial domain parameters at the valid random access opportunity:

[0362] The first message in the two-step random access process;

[0363] The first message in the four-step random access process;

[0364] The third message in the four-step random access procedure;

[0365] Configuration grant based on small data transmission;

[0366] The Physical Uplink Control Channel (PUCCH) for confirming the fourth message in the four-step random access procedure;

[0367] Random access success response message.

[0368] In the method according to the embodiments of the present application, the network-side device receives the transmission from the terminal at a valid random access opportunity, where the valid random access opportunity is a random access opportunity within the uplink sub-band of the first time domain unit, or a random access opportunity within the frequency domain of the second time domain unit (the uplink time domain unit without configured sub-bands), avoiding the occurrence of self-interference and cross-link interference, improving the system performance, and reducing the access delay.

[0369] It should be noted that this method is implemented in cooperation with the terminal that executes the method as Figure 6 shown. The implementation manner of the above method embodiments is applicable to this method and can also achieve the same technical effects.

[0370] As Figure 16 shown, the embodiments of the present application provide a transmission configuration method, including:

[0371] Step 1601, the terminal receives the spatial domain parameters sent by the network-side device;

[0372] Step 1602, the terminal performs transmission on the first uplink resource or the first downlink resource according to the spatial domain parameters;

[0373] Wherein, the first uplink resource includes resources within the uplink sub-band of the sixth time domain unit, or resources within the seventh time domain unit;

[0374] The first downlink resource includes resources within the downlink sub-band of the eighth time domain unit, or resources within the ninth time domain unit;

[0375] The seventh time domain unit is an uplink time domain unit without configured sub-bands, and the ninth time domain unit is a downlink time domain unit without configured sub-bands.

[0376] In this way, the terminal can perform transmission on the first uplink resource or the first downlink resource according to the spatial domain parameters indicated by the network, thereby avoiding the occurrence of self-interference and cross-link interference, improving the system performance, and reducing the access delay.

[0377] Wherein, the sixth time domain unit can be an uplink time domain unit, a downlink time domain unit, or a flexible time domain unit. The seventh time domain unit is a UL only time domain unit.

[0378] Among them, the eighth time domain unit may be an uplink time domain unit, a downlink time domain unit, or a flexible time domain unit. The ninth time domain unit is a UL only time domain unit.

[0379] Optionally, the first uplink resource may be an RO, especially a valid RO.

[0380] Optionally, the first downlink resource may be an SSB or a common control channel, etc.

[0381] Optionally, the first uplink resource is a resource within the uplink sub-band of the sixth time domain unit and time domain overlapping with the transmission of the SSB or the common control channel;

[0382] The first downlink resource is a resource within the downlink sub-band of the eighth time domain unit and time domain overlapping with the uplink transmission.

[0383] Among them, uplink transmission can be understood as sending an RO, or MSG 1 / MSG A / MSG3 / CG based SDT / Common PUCCH on the RO to acknowledge for MSG4 / successRAR / MSG 5 PUSCH.

[0384] Optionally, the spatial domain parameters include at least one of the following:

[0385] Spatial domain parameters corresponding to different SSBs or common control channels;

[0386] Spatial domain parameters corresponding to different uplink transmissions, where the uplink transmission is associated with the SSB.

[0387] Optionally, the spatial domain parameters corresponding to different SSBs include at least one of the following:

[0388] Spatial domain parameters for the uplink transmission associated with the SSB;

[0389] Spatial domain parameters for the downlink transmission corresponding to the uplink transmission associated with the SSB.

[0390] Thus, if the network side device configures spatial domain parameters corresponding to different SSBs or common control channels, and the spatial domain parameters are used for the uplink transmission associated with the SSB, then for the RO located in the UL SB or UL only time domain unit, especially the valid RO, it can be transmitted using the spatial domain parameters corresponding to the SSB associated with it; or, in the case where the RO overlaps with the SSB or the common control channel, it is transmitted using the spatial domain parameters corresponding to the SSB associated with it.

[0391] If the network - side device configures spatial domain parameters corresponding to different SSBs or common control channels, and the spatial domain parameters are used for the downlink transmission corresponding to the uplink transmission associated with the SSB, then for the RO, especially the valid RO, when sending the downlink transmission corresponding to the RO, the spatial domain parameters of the SSB associated with it configured by the network - side device can be adopted.

[0392] Among them, when the network - side device sends spatial domain parameters corresponding to different uplink transmissions, the spatial domain parameters are used for the terminal to receive the downlink transmission, so as to determine the spatial domain parameters adopted by the downlink transmission when the downlink transmission overlaps with the uplink transmission.

[0393] Optionally, the spatial domain parameters include the state of the transmission configuration indicator (TCI) or spatial - related information.

[0394] Specifically, the network - side device indicates the spatial domain parameters in semi - static signaling (such as SIB messages or RRC release messages) or dynamic signaling.

[0395] Optionally, the terminal uses the spatial domain parameters for transmission, and the spatial domain parameters are applied to the uplink transmission located in the UL SB, such as RO or valid RO.

[0396] Optionally, the terminal uses the spatial domain parameters for transmission, and the spatial domain parameters are applied to the uplink transmission located in the UL SB and overlapping with the SSB or common control channel, such as RO or valid RO.

[0397] Optionally, the terminal uses the spatial domain parameters for transmission, and the spatial domain parameters are applied to the uplink transmission located in the UL SB and the uplink transmission located in the UL - only time domain unit, such as RO or valid RO.

[0398] Optionally, the terminal uses the spatial domain parameters for transmission, and the spatial domain parameters are applied to the uplink transmission located in the UL SB and overlapping with the SSB or common control channel, such as RO or valid RO, and the uplink transmission located in the UL - only time domain unit and overlapping with the SSB or common control channel, such as RO or valid RO.

[0399] Optionally, the terminal uses the spatial domain parameters for reception, and the spatial domain parameters are applied to the PDCCH or PDSCH located in the DL SB.

[0400] Optionally, the terminal uses the spatial domain parameters for reception, and the spatial domain parameters are applied to the PDCCH or PDSCH located in the DL SB and overlapping with the uplink transmission (such as RO or valid RO).
