It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.
[0091] For ease of understanding, some of the contents involved in the embodiments of this application are described below:
[0092] 1. Random Access Resource Selection
[0093] The random access procedure may be a contention-based random access procedure or a non-contention-based random access procedure. The random access procedure may be a four-step random access procedure (also called a Type-1 random access procedure) or a two-step random access procedure (also called a Type-2 random access procedure).
[0094] In the contention-based four-step random access channel (RACH) process, a terminal (such as a user equipment (UE)) first sends Msg1, which contains a preamble, to the network. After the network detects the preamble, it sends Msg2 / Random Access Response (RAR), which contains the preamble number detected by the network and the uplink radio resources allocated to the UE for sending Msg3. After receiving Msg2, the UE confirms that at least one of the preamble numbers carried in Msg2 matches the number of the preamble it sent. Then, based on the resources indicated by the RAR, it sends Msg3 containing contention resolution information. After receiving Msg3, the network sends Msg4 containing contention resolution information. Upon receiving Msg4, the UE confirms that the contention resolution information matches the content sent in Msg3, thus completing the four-step random access process.
[0095] The network includes uplink grant (UL grant) information in the RAR to indicate the MSG3 Physical Uplink Shared Channel (PUSCH) scheduling information, and includes RACH preamble ID (RAPID), Temporary Cell Radio Network Temporary Identity (TC-RNTI), Time Alignment (TA), etc. 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).
[0096] 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 resource (also called random access opportunity (RACH Occasion, RO)). This situation can be understood as a UE preamble conflict. In this case, different UEs will receive the same RAR. At this time, different UEs will transmit MSG3PUSCH according to the scheduling information in the RAR UL grant. The network can only decode the PUSCH (including contention resolution information) sent by one UE on one MSG3PUSCH 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 MSG3PUSCH, the UE considers that the contention resolution is successful. If they do not match, the contention resolution is considered unsuccessful.
[0097] If the contention resolution is unsuccessful, the UE reselects a random access channel (RACH) transmission resource, performs physical random access channel (PRACH) transmission, and makes the next random access attempt.
[0098] 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 a MsgB message to the UE. If the UE does not receive MsgB within a certain period of time, the UE will increment 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 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 resources associated with the sending of the MsgA preamble and the RO. MsgA PUSCH resources are a set of PUSCH resources configured relative to each PRACH slot, including time-frequency resources and demodulation reference signal (DMRS) resources.
[0099] 2. Random Access Resource Selection and Synchronization Signal and PBCH Block (SSB) to RO Mapping
[0100] In New Radio (NR), a cell can configure multiple frequency division multiplexing (FDM) PRACH transmission opportunities (or PRACH Occasions), referred to here as ROs for simplicity, at a single PRACH transmission time location. At a given moment, the number of ROs that can be used for FDM can be: {1, 2, 4, 8}. At a given moment, there are eight RO resources distributed across different frequencies.
[0101] The random access preamble can only be transmitted on the time domain resource (RO) configured by the parameter PRACH configuration index (PRACHConfigurationIndex). The random access preamble can only be transmitted on the frequency domain resource configured by the parameter prach-FDM. The PRACH frequency domain resource 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 RO with the lowest frequency in the initial active uplink bandwidth part. Otherwise, the PRACH frequency domain resources are numbered in ascending order starting from the RO with the lowest frequency in the active uplink bandwidth part.
[0102] In NR, there is an association between the RO and the SSB (SS / PBCH block, synchronization signal / physical broadcast channel block, sometimes simply referred to as SS block, synchronization signal block) 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 based on 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.
[0103] 3. PRACH time domain resource location (period, occasion, etc.)
[0104] PRACH resources are periodic resources. In the time domain, different PRACH Preamble formats have different durations. The time domain position of PRACH resources is defined by the PRACH configuration period, radio frame index, subframe / time slot index, starting PRACH OFDM symbol index in the time slot and the number of time domain ROs in the time slot. Among them, the candidate values of the PRACH configuration period are {10, 20, 40, 80, 160} ms. In each PRACH configuration period, PRACH resources are only distributed in a valid radio frame (10ms). The valid radio frame contains one or more subframes / time slots. There is only one starting PRACH OFDM symbol index in each subframe / time slot, and there is one or more time domain ROs in a time slot. In the frequency domain, different PRACH Preamble formats and subcarrier spacing jointly determine the frequency domain bandwidth occupied by 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).
[0105] 4. SSB-RO mapping cycle
[0106] In NR, there is an association between the RO and the actual transmitted SSB (SS / PBCH block). ROs are associated with SSBs in the frequency domain (from low frequency to high frequency) and then in the time domain. One SSB may be associated with multiple consecutive ROs, or multiple SSBs may be associated with one RO (in this case, different SSBs correspond to different preambles), which is configured by the network through the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB.
[0107] After all SSBs are associated with ROs for one round, a SSB-RO mapping cycle is formed.
[0108] 5. Association period, also known as association cycle
[0109] An SSB to RO association period may contain one or more SSB-RO mapping periods.
[0110] The definition of the association period of SSB to RO is that at least one round of SSB to RO mapping is completed within the period, so that each SSB actually transmitted is mapped to at least one RO. The association period of SSB mapping to 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 Mapping between PRACH configuration period and SS / PBCH block to PRACH occasion association period. Among them, the association period is calculated from radio frame 0. Within an association period, after completing a round of SSB to RO mapping, the next round of mapping continues until the remaining ROs are insufficient to complete a round of SSB to RO mapping. If the remaining ROs are insufficient to complete a round of SSB to RO mapping, these remaining ROs are an invalid RO set. All ROs in the invalid RO set cannot be associated with SSB and cannot be used for PRACH transmission.
[0111] Table 1
[0112] Valid PRACH occasions
[0113] 1) For paired spectrum (Frequency Division Duplexing (FDD)), all PRACH occasions are valid.
[0114] 2) For unpaired spectrum (Time Division Duplexing (TDD)):
[0115] If the UE does not receive the time division multiplexing uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon), then in the current PRACH slot, the PRACH occasion does not precede the SSB and is separated from the most recent SSB by at least Ngap symbols, then the PRACH occasion is valid;
[0116] If the UE receives tdd-UL-DL-ConfigurationCommon, the PRACH occasion in the PRACH slot is considered valid if: the PRACH occasion is in an UL symbol or in the current PRACH slot, the PRACH occasion does not precede an SSB, and is separated from the most recent SSB by at least Ngap symbols, and is separated from the last downlink (DL) symbol by at least Ngap symbols.
[0117] 7. Association pattern period between SSB and RO
[0118] Because the number of valid ROs contained in the association period of SSB mapping to RO is variable under some configuration conditions, the NR protocol further defines the time domain repetition period of the association period of SSB mapping to RO through the association pattern period. The maximum value of the association pattern period of SSB mapping to RO is 160ms.
[0119] An SSB to RO association pattern period may contain one or more SSB-RO association periods, and the SSB to RO mapping is repeated based on the association pattern period.
[0120] 8. Status of the Transmission Configuration Indicator (TCI) of the Control Resource Set (CORESET)
[0121] 1) For a CORESET other than the one with index 0:
[0122] If the UE has not been provided with a configuration of TCI states by the CORESET's TCI StatesPDCCH ToAddList and TCI StatesDDCCH ToReleaseList, or has been provided with an initial configuration of more than one TCI state by the CORESET's TCI-StatesPDCCCH ToAddList or TCI-StatesDCCH ToRelaseList, but has not received a Media Access Control Control Element (MAC CE) activation command for one of the TCI states, the UE assumes that the Demodulation Reference Signal (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;
[0123] If the UE has been provided with a configuration of more than one TCI state by the CORESET's TCI StatesPDCCH ToAddList and TCI StatesDDCCH ToReleaseList as part of the current reconfiguration procedure with synchronization, but has not yet received a MAC CE activation command for one of the described TCI states, the UE assumes that the DM-RS antenna ports associated with PDCCH reception are quasi-co-located with the SS / PBCH blocks or Channel State Information-Reference Signal (CSI-RS) resources identified by the UE during the random access procedure initiated by the synchronous reconfiguration procedure.
[0124] 2) For a CORESET with index 0, the UE assumes that the DM-RS antenna ports used for PDCCH reception in the CORESET are quasi-co-located with:
[0125] One or more DL RSs configured by the TCI state indicated by the CORESET's MAC CE Activation command, if any, or
[0126] SS / PBCH blocks identified by the UE during the most recent random access procedure that was not initiated by a PDCCH order triggering a non-contention random access procedure, if no MAC CE activation command indicating the TCI state of the CORESET was received after the most recent random access procedure.
[0127] For a CORESET other than the CORESET with index 0, if a single TCI state for the CORESET is provided to the UE, or if the UE receives a MAC CE activation command for one of the TCI states provided by the CORESET, the UE assumes that the DM-RS antenna ports associated with PDCCH reception in the CORESET are quasi co-located with one or more DL RSs configured by the TCI state. For the CORESET with index 0, the UE expects Quasi Co-Location (QCL) Type D of the CSI-RS in the TCI state indicated by the MAC CE activation command of the CORESET to be provided by the SS / PBCH block;
[0128] If the UE receives a MAC CE activation command for one of the TCI states, the UE The activation command is applied in the first timeslot after the activation command is applied. Where k is the timeslot in which the UE will send the Physical Uplink Control Channel (PUCCH) with the Hybrid Automatic Repeat reQuest ACK acknowledgement (HARQ-ACK) information for the PDSCH providing the activation command, and μ is the subcarrier spacing (SCS) configuration used for the PUCCH. The activation bandwidth part (BWP) is defined as the activation BWP in the timeslot when the activation command is applied. The subcarrier spacing is u, and the number of slots contained in a subframe.
[0129] 8. Subbands non-overlapping Full duplex
[0130] Sub-band non-overlapping full-duplex can improve transmission delay and enhance coverage.
[0131] 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 an uplink (UL) slot, the network configures a UL BWP for the UE.
[0132] For the full duplex scenario, there are the following cases:
[0133] For a DL slot (configured by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated), as shown in Figure 2,
[0134] Case 1: Configure DL BWP, i.e. slot 1;
[0135] Case 2: Configure DL BWP and UL sub-band, i.e. slot 2;
[0136] For a UL slot (configured by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated), as shown in Figure 3,
[0137] Case 3: Configure UL BWP, i.e. slot 4;
[0138] Case 4: Configure UL BWP and DL sub-band, namely slot 5.
[0139] For SubBand Full Duplex (SBFD) operation, one SBFD subband consists of one resource block (RB) or a set of consecutive RBs with the same transmission direction.
[0140] The time domain unit (e.g., slot or symbol) in which the gNB operates using SBFD may be referred to as an SBFD time domain unit (e.g., slot or symbol).
[0141] In one approach, the base station and the UE can only send or receive at a time.
[0142] In one mode, the gNB side is 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.
[0143] In one approach, full-duplex is implemented on the UE side, where the gNB and UE can transmit and receive simultaneously. For full-duplex on the UE side, a larger guard band (GB) may be required to mitigate self-interference, such as a GB larger than that used for full duplex (FD) operation on the base station.
[0144] For a communication device, simultaneous UL reception and DL transmission can cause self-interference. To ensure transmission in the interfered direction, the communication device needs to have self-interference cancellation capabilities, such as reserving a guard band between the receive and transmit bands. However, this reduces UE throughput.
[0145] In the embodiment of the present application, a valid random access opportunity, that is, both the frequency domain resources and the time domain resources of this random access opportunity are valid.
[0146] In the embodiment of the present application, the units of the time domain unit include but are not limited to time slots and symbols.
[0147] In the embodiment of the present application, the time domain unit including the uplink subband (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 subband (DL SB). Among them, if the flexible time domain unit is only configured with a downlink subband (DL SB), the resources that can be used for UL transmission in the flexible time domain unit may include resources in the flexible time domain unit other than the DL SB and GB.
[0148] In the embodiment of the present application, the uplink time domain unit without subband configuration is also called UL only time domain unit; the downlink time domain unit without subband configuration is also called DL only time domain unit; the flexible time domain unit without subband configuration is also called flexible only time domain unit.
[0149] To simplify the description, the present embodiment focuses on describing uplink subbands (located in downlink time units, uplink time units, or flexible time units) and uplink time units (without subbands). Other resource types and combinations are not excluded.
[0150] In the embodiment of the present application, SSB to RO mapping may also refer to the association between downlink signals and uplink signals / resources in a general sense, such as the association between SSB and small data transmission (SDT), the association between channel state information reference signal (CSI-RS) and RO, etc.
[0151] In the embodiment of the present application, RACH Occasion (RO), which can also be understood as PRACH Occasion, refers to the time-frequency resources required for sending a PRACH sequence. Random access process, namely random access (RA).
[0152] In the embodiments of the present application, SSB and SS / PBCH block can be used interchangeably or by other names, and can refer to any module containing at least part of a synchronization signal, a broadcast signal or other downlink broadcast signal.
[0153] In the embodiment of the present application, the PRACH resource may be a PRACH time-frequency resource and / or a PRACH sequence.
[0154] In the embodiments of the present application, a shared RO refers to a PRACH sequence that is used for both one type of PRACH transmission and another type of PRACH transmission. A separate RO or a separately configured RO refers to a PRACH occasion that is additionally configured only for different types of PRACH transmissions.
[0155] In the embodiment of the present application, the RO type is any of the following: RO resources of an uplink subband, RO resources of an uplink time domain unit, RO resources of a flexible time domain unit, and RO resources spanning multiple resources. For example, RO resources spanning multiple resources are RO resources that occupy both an uplink subband and an uplink time domain unit. For simplicity of description, only RO resources of an uplink subband and RO resources of an uplink time domain unit are used as examples.
[0156] In the embodiments of the present application, the following two full-duplex modes are defined for simplicity of description:
[0157] Network full-duplex mode: full-duplex is used on the network side and half-duplex is used on the terminal side.
[0158] Terminal full-duplex mode: full-duplex is applied on the network side and full-duplex is applied on the terminal side.
[0159] Among them, half-duplex on the terminal side can be understood as the terminal can only receive DL or send UL signals or channels in a time unit (also called a time domain unit). Full-duplex on the terminal side can be understood as the terminal can simultaneously receive DL and send UL signals or channels in a time unit.
[0160] Network full-duplex mode can achieve the goals of enhancing coverage, reducing transmission delay, and improving resource utilization efficiency. Terminal full-duplex mode can achieve the above gains while improving DL (UL) throughput.
[0161] Typically, a guard band, such as GB, is reserved between UL and DL transmissions to achieve frequency isolation and reduce self-interference. The UE's self-interference mitigation capability is generally weaker than that of the gNB. For simultaneous transmission and reception on the UE side, a larger number of GBs must be reserved than on the gNB side, meaning more PRBs must be reserved as guard bands.
[0162] As shown in Figure 4, (a) shows the network-side full-duplex subband and GB configuration. Specifically, the network configures the time-frequency resources for UL (UL) SBs and DL (DL) SBs (and / or GBs). During UL SBs, the network receives UL channels or signals from the served UE. During DL SBs, the network transmits DL channels or signals to the served UE. DL transmissions can cause self-interference in UL reception.
[0163] As shown in FIG4 , (b) is the full-duplex subband configuration at the UE side. The network configures the time-frequency resources of the UL SB and DL SB (and / or GB) for the UE. The UL transmission of the UE will generate self-interference on the DL reception.
[0164] Different UEs may have different capabilities, so the GBs that need to be reserved may be different.
[0165] The embodiments of the present application use enhanced duplexing, which may also be referred to as enhanced duplex mode, XDD, enhanced full duplex, or enhanced full duplex mode. Enhanced duplexing can be expressed as supporting uplink subbands within downlink time units, supporting downlink subbands within uplink time units, or supporting at least one of uplink subbands or downlink subbands within flexible time units.
[0166] Among them, enhanced duplex can include network full duplex and terminal full duplex.
[0167] The network notifies an enhanced duplex pattern in a system information block (SIB) 1 or a master information block (MIB), including at least one of the following: an enhanced duplex configuration period, an enhanced duplex mode period, and an uplink and downlink common configuration (UL-DL config common).
[0168] For example, as shown in Figure 5, the UL-DL config common is DDDDU, with a period of 5ms, that is, the five time domain units in one period (5ms) are downlink time domain unit, downlink time domain unit, downlink time domain unit, downlink time domain unit, and uplink time domain unit, respectively. The enhanced duplex configuration is 11100 00000, the mode (enhanced duplex mode) is DUD, and the period is 10ms, that is, there are 10 time domain units in one period (10ms), and the first three time domain units are divided into three sub-bands according to the mode DUD. The enhanced duplex mode period is 10ms (the enhanced duplex mode can change for different mode periods, for example, the frequency domain sub-band is DUD, DU, UD...). As shown in Figure 5, in the two enhanced duplex mode periods, the mode in the first enhanced duplex mode period is DUD, and the mode in the second enhanced duplex mode period is DU.
[0169] The transmission processing method, configuration method, apparatus, terminal, and network-side equipment provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.
[0170] As shown in FIG6 , a transmission processing method according to an embodiment of the present application includes:
[0171] Step 601: The terminal determines a valid random access opportunity, where the valid random access opportunity includes a random access opportunity within an uplink subband of a first time domain unit, or a random access opportunity within a frequency domain of a second time domain unit; wherein the second time domain unit is an uplink time domain unit with no subband configured or a flexible time domain unit;
[0172] Step 602: The terminal transmits at the valid random access opportunity.
[0173] In this way, the terminal can determine the random access opportunity within the uplink subband 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, thereby transmitting at the valid random access opportunity, avoiding the occurrence of self-interference and cross-link interference, improving system performance, and reducing access delay.
[0174] The first time domain unit may be an uplink time domain unit, a downlink time domain unit, or a flexible time domain unit. The second time domain unit may be a UL-only time domain unit or a flexible time domain unit. For a flexible time domain unit configured with only a DL subband, the valid RO is located in resources other than the DL subband and the GB.
[0175] That is, in this embodiment, for frequency domain resources, a valid RO refers to the RO located at:
[0176] 1) UL SB (UL time domain unit, or DL time domain unit, or flexible time domain unit);
[0177] 2) Any resource on the UL only time domain unit;
[0178] 3) Resources on flexible time domain units.
[0179] If the flexible time domain unit is configured with only DL SB, the effective RO is located in resources other than the DL SB and GB including the flexible time domain unit. Any resource on the UL only time domain unit may include any resource on the flexible only time domain unit.
[0180] Optionally, in this embodiment, the terminal can obtain the location of one or more ROs before executing step 601, such as when the network side device configures an RO set or pre-defines multiple ROs. Further, the terminal can determine a valid RO from the one or more ROs.
[0181] It should be noted that the method in the embodiment of the present application is preferably applied to a terminal in an SBFD communication scenario.
[0182] Optionally, in this embodiment, the terminal determines a valid random access opportunity, including:
[0183] The terminal obtains the network side device configuration or predefined rules;
[0184] The terminal determines, based on the rule, the valid random access opportunity among the random access opportunities configured by the network side device;
[0185] The rule includes one of the following:
[0186] The effective random access opportunity is located in the uplink subband of the first time domain unit; or
[0187] When the terminal is not configured with the first information, the effective random access opportunity is located in the uplink subband of the first time domain unit, and the effective random access opportunity does not precede the synchronization signal block SSB in the random access time slot, and the interval between the effective random access opportunity and the first SSB is greater than or equal to the first value; when the terminal is configured with the first information, the effective random access opportunity is located in the uplink subband of the first time domain unit, and the effective random access opportunity does not precede the SSB in the random access time slot, the interval between the effective random access opportunity and the first SSB is greater than or equal to the second value, and the interval between the effective random access opportunity and the third time domain unit is greater than or equal to the second value; wherein, the first SSB is the SSB that is located before the effective random access opportunity and has the smallest interval with the effective random access opportunity; or;
[0188] The effective random access opportunity is located in the uplink subband of the first time domain unit, and the interval between the effective random access opportunity and the fourth time domain unit in the random access time slot is greater than or equal to a third value;
[0189] The effective random access opportunity is located in the uplink subband of the first time domain unit, and the interval between the effective random access opportunity and the fifth time domain unit in the random access time slot is greater than or equal to a fourth value.
[0190] Optionally, the third time domain unit is a downlink time domain unit on the random access time slot that is located before the effective random access opportunity and has the smallest interval with the effective random access opportunity, and no subband is configured on the third time domain unit;
[0191] The fourth time domain unit is a 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 with the valid random access opportunity, and no subband is configured on the fourth time domain unit;
[0192] The fifth time domain unit is a downlink or uplink time domain unit in the random access time slot, located after the valid random access opportunity and having the smallest interval with the valid random access opportunity, and no subband is configured on the fifth time domain unit.
[0193] Optionally, the first information is time division multiplexing uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon).
[0194] Additionally, optionally, in this embodiment, the terminal determines, based on the rule, the valid random access opportunity in the random access opportunities configured by the network-side device, including:
[0195] When receiving the time division multiplexing uplink and downlink common configuration, the terminal determines that the random access opportunity that is located in the uplink subband of the first time domain unit and has a spacing with the fourth time domain unit in the random access time slot greater than or equal to a third value is the valid random access opportunity.
[0196] That is, only when the terminal configures tdd-UL-DL-ConfigurationCommon, the validity of the RO in the uplink subband of the first time domain unit will be determined by whether the interval between it and the fourth time domain unit in the random access time slot is greater than or equal to the third value.
[0197] Optionally, the first value and the second value are equal to the interval N gap The value of the symbol. N gap Related to the subcarrier spacing, for example, when the subcarrier spacing is 1.25kHz or 5kHz, N gap Equal to 0; subcarrier spacing is 15kHz or 30kHz or 60kHz or 120kHz, N gap Equal to 2.
[0198] Of course, the first value and the second value may also take other values, which are configured or predefined by the network side device. Moreover, the first value and the second value may be the same or different.
[0199] Optionally, the third value and the fourth value may also be configured or predefined by the network side device as the same or different values.
[0200] Furthermore, in this embodiment, the rules can be understood as requirements that a valid RO must meet in the time domain.
[0201] Among them, Rule 1: The valid random access opportunity is located in the uplink subband of the first time domain unit.
[0202] That is, for the RO resources of the UL SB of the first time domain unit, all ROs are valid.
[0203] Rule 2: When the terminal is not configured with tdd-UL-DL-ConfigurationCommon, the effective random access opportunity is located in the uplink subband of the first time domain unit, and the effective random access opportunity does not precede the synchronization signal block SSB in the random access time slot, and the interval with the first SSB is greater than or equal to the first value; when the terminal is configured with tdd-UL-DL-ConfigurationCommon, the effective random access opportunity is located in the uplink subband of the first time domain unit, and the effective random access opportunity does not precede the SSB in the random access time slot, the interval with the first SSB is greater than or equal to the second value, and the interval with the third time domain unit is greater than or equal to the second value.
[0204] Here, for an RO resource, the RO does not precede the SSB, which can be understood as, in the slot where the RO is located, that is, the RO is located in the current PRACH slot, and the RO is located after the last SSB in the SSB of the slot; the first SSB is the SSB closest to the RO in the SSB of the slot; the third time domain unit is the DL only symbol in the current PRACH slot that is located before the RO and closest to the RO.
[0205] Specifically, both the first value and the second value may be Ngap, and the unit is symbol. Therefore, for the RO resource of the UL SB of the first time domain unit,
[0206] If the UE does not receive tdd-UL-DL-ConfigurationCommon, then in the current PRACH slot, if the RO does not precede the SSB and is separated from the most recent SSB by at least Ngap symbols, the RO is considered valid;
[0207] If the UE receives tdd-UL-DL-ConfigurationCommon, then in the current PRACH slot, the RO does not precede the SSB, is at least Ngap symbols away from the most recent SSB, and is at least Ngap symbols away from the last DL-only symbol, the RO is considered valid.
[0208] Ngap can be predefined or configured by the network, for example, Ngap is greater than or equal to 0.
[0209] Rule 3: The valid random access opportunity is located in the uplink subband 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 time slot is greater than or equal to a third value;
[0210] The effective random access opportunity is located in the uplink subband of the first time domain unit, and the interval between the effective random access opportunity and the fifth time domain unit in the random access time slot is greater than or equal to a fourth value.
[0211] Here, for an RO resource, the fourth time domain unit is the DL only symbol or UL only symbol located before the RO and closest to the RO in the current PRACH slot; the fifth time domain unit is the DL only symbol or UL only symbol located after the RO and closest to the RO in the current PRACH slot.
[0212] Specifically, the third value and the fourth value may be the same or different, and the unit is symbol, such as the third value is X1 and the fourth value is X2. Therefore, for the RO of the UL SB of the first time domain unit,
[0213] If the UE does not receive tdd-UL-DL-ConfigurationCommon, or the UE receives tdd-UL-DL-ConfigurationCommon, then in the slot where a RO is located, that is, the current PRACH slot, the RO is considered valid if it is separated from the most recent DL only symbol or UL only symbol by at least X1 symbols;
[0214] In the current PRACH slot, if the RO is separated from the next most recent DL-only symbol or UL-only symbol by at least X2 symbols, the RO is considered valid.
[0215] For example, assuming that the terminal is not configured with time division multiplexing (TDM) for both uplink and downlink, as shown in Figure 7, a random access time slot includes a DL-only time domain unit, a DL-only 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.
[0216] Therefore, since RO1 is located within the UL SB of the DL time domain unit, after SSB2 in its random access slot, and separated from SSB2 by 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.
[0217] Assuming that the terminal is configured with time division multiplexing (TDM) for both uplink and downlink, as shown in Figure 7, a random access time slot includes a DL-only time domain unit, a DL-only 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.
[0218] Therefore, since RO1 is located within the UL SB of the DL time domain unit, after SSB2 in its random access slot, and separated from SSB2 by Ngap symbols, and separated from the DL-only time domain unit by more 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.
[0219] Optionally, the above rule for judging the validity of the RO time domain can be extended to consider whether a RO overlaps with an SSB.
[0220] Rule 2 can be expanded to:
[0221] If the UE does not receive tdd-UL-DL-ConfigurationCommon, then in the current PRACH slot, except for the RO that overlaps with the SSB, the RO does not precede the SSB and is separated from the most recent SSB by at least Ngap symbols, the RO is considered valid;
[0222] If the UE receives tdd-UL-DL-ConfigurationCommon, then in the current PRACH slot, except for the RO overlapping with the SSB, the RO does not precede the SSB and is at least Ngap symbols away from the most recent SSB and at least Ngap symbols away from the last DL-only symbol, the RO is considered valid.
[0223] The UE does not expect an SSB to be mapped to a RO that overlaps in the time domain or to the preceding RO.
[0224] In the above content, it is known that the terminal will determine the valid RO from the one or more ROs obtained. Specifically, the one or more ROs may be configured by the network side device. Therefore, in the embodiment of the present application, optionally, the method further includes:
[0225] The terminal receives configuration information of random access opportunity sent by the network side device;
[0226] Wherein, 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;
[0227] The first configuration is a configuration of a random access opportunity located in an uplink subband of the first time domain unit;
[0228] The second configuration is a configuration of a random access opportunity located in the frequency domain of the second time domain unit.
[0229] 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 independently configure the ROs in the first time domain unit and the ROs in the second time domain unit. For example, when uniformly configured, the ROs in the first time domain unit and the ROs in the second time domain unit occupy the same frequency domain resources; when independent configuration is used, the ROs in the first time domain unit and the ROs in the second time domain unit occupy different frequency domain resources.
[0230] Specifically, as shown in Figure 8, the RO in the UL subband and the RO in the UL-only time-domain unit use the same RO configuration, including RO1-RO6, that is, they use the same frequency domain resources. However, since RO1-RO3 in the DL time-domain unit are located within the GB and UL SB, RO1-RO3 in the DL time-domain unit (ROs circled in dashed circles) are unavailable. Therefore, the RO of the UL SB in the DL time-domain unit is the RO of the UL-only time-domain unit, obtained by removing the RO located in the unavailable frequency domain resources. Therefore, for the RO in the DL time-domain unit, the terminal will determine the valid RO among RO4-RO6, and RO4-RO6 need to be renumbered as RO1-RO3.
[0231] Specifically, as shown in FIG9 , the RO of the UL subband and the RO of the UL only time domain unit are independently configured, RO1 and RO2 are located in the UL SB, and their frequency domain positions are different from the frequency domain resources of RO1 and RO2 of the UL only time domain unit.
[0232] In addition, in this embodiment, the terminal transmits on the valid random access opportunity, including:
[0233] The terminal receives the spatial domain parameters sent by the network side device;
[0234] The terminal sends, according to the spatial domain parameter, at least one of the following on the valid random access opportunity:
[0235] The first message in a two-step random access process;
[0236] The first message in the four-step random access process;
[0237] The third message in the four-step random access process;
[0238] Configuration authorization based on small data transmission;
[0239] Common physical uplink control channel PUCCH used to confirm the fourth message in the four-step random access process;
[0240] Random access success response message.
[0241] That is, the terminal can send at least one of the following on a valid RO: the first message (MSG A) in the two-step random access process, the first message (MSG1) in the four-step random access process, the third message (MSG3) in the four-step random access process, a configuration grant based on small data transmission (CG based SDT), a PUCCH used to acknowledge the fourth message in the four-step random access process (Common PUCCH to acknowledge for MSG4), and a random access success response message (successRAR). Of course, the transmissions on a valid RO are not limited to the above and may also include MSG5. The spatial parameters used by the valid RO are indicated by the network-side device.
[0242] Optionally, the spatial domain parameter includes a status of a transmission configuration indicator (TCI) or spatial related information (SpatialRelationInfo, SRI).
[0243] Specifically, the network side device indicates the spatial domain parameters in semi-static signaling (such as a SIB message or an RRC release message) or dynamic signaling.
[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, such as a valid RO.
[0245] 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 a common control channel (eg, PDCCH and PDSCH carrying system information), such as a valid RO.
[0246] 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 the RO located in the UL only time domain unit, such as the valid RO.
[0247] 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 common control channel, such as the valid RO, and the RO located in the UL only time domain unit and overlapping with the SSB or common control channel, such as the valid RO.
[0248] Optionally, the airspace parameter sent by the network-side device includes at least one of the following:
[0249] Airspace parameters corresponding to different SSBs or common control channels;
[0250] Spatial parameters corresponding to different uplink transmissions, where the uplink transmissions are associated with SSB.
[0251] 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 RO, especially effective RO.
[0252] The airspace parameters corresponding to the different SSBs include at least one of the following:
[0253] Spatial parameters for uplink transmissions associated with SSB;
[0254] Spatial parameters for downlink transmissions corresponding to uplink transmissions associated with SSBs.
[0255] In this way, if the network side device configures the spatial parameters corresponding to different SSBs or common control channels, and the spatial parameters are used for uplink transmission associated with the SSB, then for the RO resources located in the UL SB or UL only time domain unit, especially the valid RO resources, the spatial parameters corresponding to the SSB associated with it can be used for transmission; or, when the RO overlaps with the SSB or common control channel, the spatial parameters corresponding to the SSB associated with it can be used for transmission.
[0256] If the network-side device configures spatial parameters corresponding to different SSBs or common control channels, and the spatial parameters are used for the downlink transmission corresponding to the uplink transmission associated with the SSB, then for the RO, especially the valid RO, the spatial parameters of the SSB associated with it configured by the network-side device can be used when sending the downlink transmission corresponding to the RO. Here, the downlink transmission corresponding to the RO can be understood as the downlink transmission sending the relevant information of the RO, such as the RO sending MSG1 and the downlink transmission sending 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.
[0257] When the network side device sends spatial domain parameters corresponding to different uplink transmissions, the spatial domain parameters are used by the terminal to receive downlink transmissions, so as to determine the spatial domain parameters used for downlink transmission when the downlink transmission overlaps with the uplink transmission.
[0258] Here, downlink transmission can be understood as coreset, or PDCCH or PDSCH of coreset.
[0259] The terminal determines whether to adopt the spatial parameters configured by the network based on the overlap between UL transmission and DL transmission.
[0260] Optionally, the terminal adopts the spatial domain parameters for reception, and the spatial domain parameters are applied to the PDCCH or PDSCH located in the DL SB.
[0261] Optionally, the terminal adopts the spatial domain parameters for reception, where the spatial domain parameters are applied to a PDCCH or PDSCH located in a DL SB and overlapping with a RO (such as a valid RO).
[0262] Optionally, the terminal adopts the spatial domain parameters for reception, and the spatial domain parameters are applied to the PDCCH or PDSCH located in the DL SB and the DL only time domain unit.
[0263] Optionally, the terminal uses the spatial domain parameters for reception, and the spatial domain parameters are applied to PDCCH or PDSCH located in DL SB and overlapping with RO (such as valid RO), and PDCCH or PDSCH located in DL only time domain unit and overlapping with RO (such as valid RO).
[0264] In this embodiment, the PDCCH carries MSG2, MSGB or MSG4, and the PDSCH carries MSG2, MSGB or MSG4.
[0265] Optionally, the network side device may configure a set of spatial parameters for the UE, so as to adopt corresponding spatial parameters when uplink transmission (such as valid RO) overlaps with different SSBs or common control channels in time domain.
[0266] For example, the spatialRelationInfo corresponding to the UL transmission is configured for each SSB index, as shown in Table 2 below:
[0267] Table 2
[0268] Among them, spatialRelationInfo k1, k2, ... kn are quasi-orthogonal to the spatial directions of SSB index i+1, i+2, i+n, respectively, thereby reducing self-interference and CLI.
[0269] For example, for a terminal, when MSG 1 information transmission overlaps with SSB index i+1 in the time domain, spatialRelationInfo k1 is used; when MSG3 transmission (i.e., transmission of PUSCH carrying MSG3) overlaps with SSB index i+2 in the time domain, spatialRelationInfo k2 is used; when CG based SDT transmission (i.e., transmission of PUSCH carrying small data) overlaps with SSB index i+n in the time domain, spatialRelationInfo kn is used. And so on.
[0270] Optionally, the network may configure a set of spatial parameters for the UE, for use when downlink transmission overlaps with uplink transmission (eg, RO) associated with different SSBs or common control channels in the time domain using corresponding spatial parameters (TCI state).
[0271] For example, the TCI state for DL transmission corresponding to each SSB index (per SSB index) is configured as shown in Table 3 below:
[0272] Table 3
[0273] The spatial directions of the UL transmissions associated with TCI states j1, j2, ..., jn and SSB indexes i+3, i+4, ..., i+n-2 are quasi-orthogonal, thereby reducing self-interference and CLI.
[0274] For example, for a terminal, when the PDCCH / PDSCH of MSG 2 overlaps with the UL transmission time domain associated with SSB index i+3, the UL transmission associated with SSB index i+3 uses TCI state i+3, then the received MSG 2 uses TCI state j1; when the PDCCH of MSG4 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 MSG4 uses TCI state j2; when the PDSCH of MSG 4 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 PDSCH of MSG 4 uses TCI state jn. And so on.
[0275] Optionally, in this embodiment, the network side device only configures the spatial domain parameters of UL transmission located in UL SB, or only configures the spatial domain parameters of DL reception located in DL SB, or simultaneously configures the spatial domain parameters of UL transmission located in UL SB and the spatial domain parameters of DL reception in DL SB.
[0276] When only the spatial domain parameters of UL transmission located in the UL SB are configured, or only the spatial domain parameters of DL reception located in the DL SB are configured, the purpose of reducing SI and CLI can be achieved.
[0277] When the spatial parameters for UL transmission in a UL SB and the spatial parameters for DL reception in a DL SB are configured simultaneously, that is, the network configures both the spatial parameters for UL transmission in a UL SB and the spatial parameters for DL reception in a DL SB, these two spatial parameters should have strong orthogonality or a weak QCL relationship to ensure small SI and CLI, as shown in Table 4 below:
[0278] Table 4
[0279] Optionally, the network side device may configure {UL spatial domain parameters, DL spatial domain parameters} to characterize the association relationship between UL transmission and DL reception. For example, as shown in Table 5 below:
[0280] Table 5
[0281] UL spatial parameters, i.e., spatial parameters used for uplink transmission associated with the SSB, can be spatial parameters used for sending MSG 1 / MSG A / MSG 3 / CG based SDT / Common PUCCH to ackowledge for MSG 4 / success RAR / MSG 5 PUSCH. In one embodiment, they can be spatial parameters used for the RO or effective RO associated with the SSB.
[0282] The DL spatial parameters, i.e., the spatial parameters used for the downlink transmission corresponding to the uplink transmission associated with the SSB, may be the spatial parameters used for receiving the PDCCH of MSG2 / MSGB / MSG 4, or the spatial parameters used for the PDSCH of MSG2 / MSGB / MSG 4.
[0283] The spatial parameters kn and jn can be different from the spatial parameters represented by the SSB index i+n, so as to achieve the purpose of suppressing SI and CLI.
[0284] For example, as shown in Figure 10, the network-side device configures {UL airspace parameters, DL airspace parameters} of SSB index i+3, then the terminal sends RO i+3 associated with SSB index i+3 located in the UL SB (the time-frequency resources of the UE preamble code are located within the RO), and uses the UL airspace parameters (SRI k3) corresponding to the configured SSB index i+3; the terminal receives coreset i+3 located in the DL SB corresponding to RO i+3, and uses the DL airspace parameters (TCI state j3) corresponding to the configured SSB index i+3. Among them, the airspace parameters for transmitting RO i+3 should be quasi-orthogonal to the airspace parameters of coreset i+2, and the airspace parameters for receiving coreset i+3 should be quasi-orthogonal to the airspace parameters of RO i+4, thereby ensuring a lower SI or CLI.
[0285] The following describes the use of airspace parameters in the embodiments of this application in conjunction with specific scenarios:
[0286] Example 1, as shown in FIG11 , for valid RO i+1 and RO i+2, RO i+1 is associated with SSB i+1, RO i+2 is associated with SSB i+2, RO i+1 and SSB i+3 overlap in time domain, and RO i+2 and SSB i+4 overlap in time domain.
[0287] The downlink transmission of SSB i+3 on the network side will generate self-interference to the uplink receiving UE sending the preamble on RO i+1. At the same time, the UE sending the preamble on RO i+1 will generate CLI for other UEs receiving SSB i+3. Therefore, the network can instruct UEs using RO i+1 to send the preamble with a spatial parameter (SRI k1) that is (quasi) orthogonal to SSB i+3, thereby reducing self-interference and CLI.
[0288] Here, SSB can represent a DL spatial parameter, such as TCI state i+1, and the configured UL spatial parameter SRI k1 can be in a different direction from TCI state i+1, thereby achieving suppression of spatial self-interference and CLI.
[0289] It should be noted that if TCI state i+1 represented by SSB i+1 has good quasi-orthogonality with TCI state i+3 represented by SSB i+3, then the configured UL airspace parameters can be equal to the airspace parameters represented by SSB i+1.
[0290] Among them, the UL Tx Spatial domain filter is the same as the DL TCI state (which can be understood as the UL spatial domain parameter is the same as the DL spatial domain parameter), which means that the UE receives a signal or channel sent by the base station and sends a UL signal or channel to the base station in the opposite direction.
[0291] If the RO i+1 associated with SSB i+1 is located in the UL only time domain unit, the beam used by the UE to send the preamble in RO i+1 can be based on implementation (the UE determines the beam to be used) or can be specified by the protocol or configured by the network, such as the TCI state i+1 or the spatial parameter k1 of SSB i+1.
[0292] Example 2, as shown in Figure 12, the network's downlink transmission in coreset i+1 (associated SSB i+1) will generate self-interference to the uplink receiving UE sending the preamble in RO i+3 (associated SSB i+3). At the same time, the UE sending the preamble in RO i+3 will generate CLI for other UEs receiving the PDCCH of coreset i+1. Therefore, the network can instruct the UE using coreset i+1 to receive PDCCH a spatial parameter (TCI state j1), which is (quasi) orthogonal to the spatial parameter used to send the preamble in RO i+3 (associated SSB i+3), thereby reducing self-interference and CLI.
[0293] The coreset i+1 associated with SSB i+1 can use the same TCI state i+1 as SSB i+1, and the configured DL spatial parameter TCI state j1 can be in a different direction from TCI state i+1, thereby achieving suppression of spatial self-interference and CLI.
[0294] It should be noted that if the TCI state i+1 represented by SSB i+1 has good quasi-orthogonality with the spatial domain parameters of the RO associated with SSB i+3 (represented by the same Tx Spatial domain filter as TCI state i+3), then the spatial domain parameters TCI state j1 can use the same SSB i+1 spatial domain parameters.
[0295] Optionally, if 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 PDCCH and PDSCH scheduled by PDSCH in coreset i+1 can be based on the implementation (the UE determines the beam to be used by itself), or can be specified by the protocol or configured by the network, such as TCI state i+1 or TCI stae j1 for SSB i+1.
[0296] In the embodiment of the present application, for a time window (mapping cycle, association cycle, association pattern period), the order of mapping SSB to RO can be configured or predefined by the network. For example, the mapping of SS / PBCH block indexes to valid RO can be in the following order:
[0297] 1. The Preamble in each valid RO increases in order of Preamble index;
[0298] 2. When RACH FDM is configured (i.e., multiple valid ROs in the frequency domain), the frequency domain index is incremented;
[0299] 3. When multiple valid ROs are configured within a PRACH time slot, the index within the PRACH time slot is incremented;
[0300] 4 When multiple PRACH time slots are configured, the PRACH time slot index is incremented.
[0301] In an embodiment of the present application, within a mapping cycle, association cycle, and association pattern cycle, the mapping of SSB to RO is determined according to the uplink and downlink configuration, enhanced duplex configuration, and the effective RO in the UL SB and UL time domain unit determined by the enhanced duplex mode cycle.
[0302] The RO located in the UL SB and the RO located in the UL only time domain unit are configured independently.
[0303] Optionally, the SSB to RO mapping includes:
[0304] All SSBs are mapped to two types of ROs;
[0305] All SSBs are mapped to RO located in UL SB;
[0306] All SSBs are mapped to ROs located in the UL time domain unit.
[0307] For example, as shown in Figure 13, SSB1 is mapped to RO 1-1 located in UL SB (UL SB in UL symbol) and RO 1-2 located in UL time domain unit (UL only symbol); SSB2 is mapped to RO 2-1 located in UL SB (UL SB in UL time domain unit) and RO 2-2 located in UL time domain unit (UL only symbol).
[0308] A PRACH configuration includes the RO of a UL SB and the RO of a UL time domain unit (unconfigured SB). An SSB is mapped to at least one of the RO of a UL SB and the RO of a UL time domain unit.
[0309] Optionally, at least RO in which all SSBs are mapped to all UL time domain units is supported.
[0310] In the embodiment of the present application, the mapping from SSB to RO can be divided into more types.
[0311] For networks and terminals supporting SBFD, there are usually four types of time domain units (symbols or slots), including: DL time domain unit (not configured with SB), DL time domain unit configured with UL SB, UL time domain unit configured with DL SB, and UL time domain unit (not configured with SB).
[0312] As shown in FIG14 , for a configured RO resource (set) (PRACH occasions Physical random-access channel occasions), there may be two types of configuration situations, namely
[0313] Case 1: RO resources (sets) are configured in a UL subband (can be in UL symbols, DL or flexible symbols), such as type A;
[0314] Case 2: RO resources (sets) are configured in one UL time domain unit (no DL subband is configured), such as Type B.
[0315] Furthermore, the configured RO resources (sets) can be further divided according to whether they overlap with the SSB time domain:
[0316] 1) Configured RO Resource (Set) / Type 1: RO resources (sets) are configured in a UL signal block (SB) within a DL symbol where an SSB or common DL channel exists, meaning they overlap in time domain with the SSB or common DL channel. In this case, a UE's uplink transmission can interfere with the SSB reception of other UEs, a phenomenon known as cross-link interference. If a UE uses this SSB for measurement or decoding of common DL channels, it will also experience self-interference.
[0317] 2) Configured RO Resource(s) / Type 2: RO resources(s) are configured in a UL SB in a DL symbol where no SSB or common DL channel exists, i.e., they do not overlap in time domain with the SSB / common DL channel. In this case, uplink transmissions by one UE can interfere with the reception of DL channels or signals (e.g., PDCCH, PDSCH, CSI-RS, etc.) by other UEs.
[0318] 3) Configured RO resource (set) / Type 3: RO resource (set) is configured in the UL SB of one UL symbol, and the interference situation is similar to type 2.
[0319] 4) Configured RO resource (set) / Type 4: RO resource (set) is configured in one UL symbol, and there is no cross-link interference.
[0320] If the SS-RSRP of a certain SSB is greater than rsrp-ThresholdSSB, the SSB greater than rsrp-ThresholdSSB is selected; otherwise, any SSB is selected (the SS-RSRP of multiple SSBs is greater than rsrp-ThresholdSSB).
[0321] When selecting a CSI-RS, the CSI-RSRP of the CSI-RS is compared with the parameter rsrp-ThresholdSSB. If the CSI-RSRP of a certain CSI-RS is greater than rsrp-ThresholdCSI-RS, the CSI-RS greater than rsrp-ThresholdCSI-RS is selected.
[0322] Whether the flexible time domain unit is a valid resource for UL transmission may be based on the following rules:
[0323] (1) Flexible time domain units are not configured for UL and DL directions;
[0324] The network may configure the time domain unit to be a resource for effective UL transmission (eg, RO).
[0325] (2) Configure flexible time domain units for UL SB;
[0326] The network may configure the UL SB of the time domain unit to be a resource for valid UL transmission (eg, RO).
[0327] (3) Configure flexible time domain units for DL SB;
[0328] The network may configure the resources other than the DL SB and GB of the time domain unit to be resources for valid UL transmission (eg, RO).
[0329] UL transmission (eg, RO) that overlaps with the GB frequency domain is an invalid resource.
[0330] Optionally, RO type classification can be based on the preamble format configured within the RO (e.g., preamble formats of different lengths). An RO resource can be associated with one preamble format, and the RO can occupy at least one symbol or slot. An SSB can be associated with at least one type of RO, and different ROs can contain different preamble formats.
[0331] A method for selecting different RO types may be based on a threshold of received signal strength configured by the network. For example, the network configures two thresholds per SSB, threshold A and threshold B.
[0332] For example, the UE first measures the RSRP X of the SSB. If the RSRP X of an SSB is greater than or equal to the threshold A, the UE selects the RO type A associated with the SSB for random access. The RO type can be associated with a short preamble format. If the RSRP X of an SSB is measured, and the threshold B<=x<threshold A, the UE selects the RO type B associated with the SSB, and the RO type is associated with a long preamble format.
[0333] In addition, the network can configure or predefine a rule. If an SSB is configured with only one associated RO type, the UE can select the SSB based on the RO type. For example, if SSB i is configured with only an associated RO type with a short preamble format, and the UE measures the RSRP X of SSB i and finds that it meets threshold B <= X < threshold A, and the UE does not have an available long preamble format, the UE will not reside on that SSB. The UE selects another SSB and applies the above rule. This allows the UE to achieve better coverage performance by using the long preamble format.
[0334] The method in the embodiment of the present application can be used for SDT, SRS transmission before random access, which is not limited here.
[0335] In summary, the method of the embodiment of the present application reduces self-interference and cross-link interference, improves resource utilization, reduces access delay, and improves coverage.
[0336] As shown in FIG15 , a transmission processing method according to an embodiment of the present application includes:
[0337] 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 subband of a first time domain unit, or a random access opportunity within a frequency domain of a second time domain unit;
[0338] The second time domain unit is an uplink time domain unit or a flexible time domain unit that is not configured with a subband.
[0339] Optionally, the valid random access opportunity is a random access opportunity that satisfies a specific rule;
[0340] The rule includes one of the following:
[0341] The effective random access opportunity is located in the uplink subband of the first time domain unit; or
[0342] When the first information is not configured for the terminal, the effective random access opportunity is located in the uplink subband of the first time domain unit, and the effective random access opportunity does not precede the synchronization signal block SSB in the random access time slot, and the interval between the effective random access opportunity and the first SSB is greater than or equal to the first value; when the first information is configured for the terminal, the effective random access opportunity is located in the uplink subband of the first time domain unit, and the effective random access opportunity does not precede the SSB in the random access time slot, the interval between the effective random access opportunity and the first SSB is greater than or equal to the second value, and the interval between the effective random access opportunity and the third time domain unit is greater than or equal to the second value; wherein the first SSB is the SSB that is located before the effective random access opportunity and has the smallest interval with the effective random access opportunity; or;
[0343] The effective random access opportunity is located in the uplink subband of the first time domain unit, and the interval between the effective random access opportunity and the fourth time domain unit in the random access time slot is greater than or equal to a third value;
[0344] The effective random access opportunity is located in the uplink subband of the first time domain unit, and the interval between the effective random access opportunity and the fifth time domain unit in the random access time slot is greater than or equal to a fourth value.
[0345] Optionally, the third time domain unit is a downlink time domain unit on the random access time slot that is located before the effective random access opportunity and has the smallest interval with the effective random access opportunity, and no subband is configured on the third time domain unit;
[0346] The fourth time domain unit is a 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 with the valid random access opportunity, and no subband is configured on the fourth time domain unit;
[0347] The fifth time domain unit is a downlink or uplink time domain unit in the random access time slot, located after the valid random access opportunity and having the smallest interval with the valid random access opportunity, and no subband is configured on the fifth time domain unit.
[0348] Optionally, the first information is a time division multiplexing uplink and downlink common configuration.
[0349] Optionally, the first value and the second value are equal to the interval N gap The value of the symbol.
[0350] Optionally, the method further includes:
[0351] The network side device sends configuration information of random access opportunity;
[0352] Wherein, 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;
[0353] The first configuration is a configuration of a random access opportunity located in an uplink subband of the first time domain unit;
[0354] The second configuration is a configuration of a random access opportunity located in the frequency domain of the second time domain unit.
[0355] Optionally, the method further includes:
[0356] The network side device sends the spatial parameters;
[0357] The network device receives a transmission from a terminal at a valid random access opportunity, comprising:
[0358] The network device receives at least one of the following items sent by the terminal at the valid random access opportunity according to the spatial domain parameter:
[0359] The first message in a two-step random access process;
[0360] The first message in the four-step random access process;
[0361] The third message in the four-step random access process;
[0362] Configuration authorization based on small data transmission;
[0363] Common physical uplink control channel PUCCH used to confirm the fourth message in the four-step random access process;
[0364] Random access success response message.
[0365] In the method of the embodiment of the present application, the network side device receives the transmission of the terminal at the effective random access opportunity, and the effective random access opportunity is a random access opportunity within the uplink subband of the first time domain unit, or a random access opportunity within the frequency domain of the second time domain unit (an uplink time domain unit without a subband), thereby avoiding the occurrence of self-interference and cross-link interference, improving system performance, and reducing access delay.
[0366] It should be noted that this method is implemented in conjunction with the terminal that executes the method shown in Figure 6. The implementation method of the above method embodiment is applicable to this method and can also achieve the same technical effect.
[0367] As shown in FIG16 , an embodiment of the present application provides a transmission configuration method, including:
[0368] Step 1601: The terminal receives airspace parameters sent by the network side device;
[0369] Step 1602: The terminal transmits on a first uplink resource or a first downlink resource according to the spatial domain parameter;
[0370] The first uplink resource includes resources within the uplink subband of the sixth time domain unit, or resources within the seventh time domain unit;
[0371] The first downlink resources include resources within the downlink subband of the eighth time domain unit, or resources within the ninth time domain unit;
[0372] The seventh time domain unit is an uplink time domain unit not configured with a subband, and the ninth time domain unit is a downlink time domain unit not configured with a subband.
[0373] In this way, the terminal can transmit the first uplink resource or the first downlink resource according to the spatial parameters indicated by the network, thereby avoiding the occurrence of self-interference and cross-link interference, improving system performance, and reducing access delay.
[0374] The sixth time domain unit may 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.
[0375] 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.
[0376] Optionally, the first uplink resource may be a RO, in particular a valid RO.
[0377] Optionally, the first downlink resource may be an SSB or a common control channel, etc.
[0378] Optionally, the first uplink resource is a resource within the uplink subband of the sixth time domain unit, overlapping with the SSB or common control channel transmission time domain;
[0379] The first downlink resource is a resource in the downlink sub-band of the eighth time domain unit and overlaps with the uplink transmission time domain.
[0380] Among them, uplink transmission can be understood as sending RO, or MSG 1 / MSG A / MSG3 / CG based SDT / Common PUCCH on RO to ackowledge for MSG4 / successRAR / MSG 5PUSCH.
[0381] Optionally, the airspace parameter includes at least one of the following:
[0382] Airspace parameters corresponding to different SSBs or common control channels;
[0383] Spatial parameters corresponding to different uplink transmissions, where the uplink transmissions are associated with SSB.
[0384] Optionally, the airspace parameters corresponding to different SSBs include at least one of the following:
[0385] Spatial parameters for uplink transmissions associated with SSB;
[0386] Spatial parameters for downlink transmissions corresponding to uplink transmissions associated with SSBs.
[0387] In this way, if the network side device configures the spatial parameters corresponding to different SSBs or common control channels, and the spatial parameters are used for 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 parameters corresponding to the SSB associated with it; or, when the RO overlaps with the SSB or common control channel, it can be transmitted using the spatial parameters corresponding to the SSB associated with it.
[0388] However, if the network side equipment configures the spatial parameters corresponding to different SSBs or common control channels, and the spatial parameters are used for the downlink transmission corresponding to the uplink transmission associated with the SSB, then for RO, especially the valid RO, the spatial parameters of the SSB associated with it configured by the network side equipment can be used when sending the downlink transmission corresponding to the RO.
[0389] When the network side device sends spatial domain parameters corresponding to different uplink transmissions, the spatial domain parameters are used by the terminal to receive downlink transmissions, so as to determine the spatial domain parameters used for downlink transmission when the downlink transmission overlaps with the uplink transmission.
[0390] Optionally, the spatial domain parameter includes the status of a transmission configuration indicator TCI or space-related information.
[0391] Specifically, the network side device indicates the spatial domain parameters in semi-static signaling (such as a SIB message or an RRC release message) or dynamic signaling.
[0392] Optionally, the terminal uses the spatial domain parameters for transmission, and the spatial domain parameters are applied to uplink transmission located in the UL SB, such as RO or effective RO.
[0393] Optionally, the terminal uses the spatial domain parameters for transmission, and the spatial domain parameters are applied to uplink transmission located in the UL SB and overlapping with the SSB or the common control channel, such as RO or effective RO.
[0394] Optionally, the terminal uses the spatial domain parameters for transmission, and the spatial domain parameters are applied to uplink transmission in a UL SB and a UL only time domain unit, such as RO or effective RO.
[0395] Optionally, the terminal uses the spatial domain parameters for transmission, and the spatial domain parameters are applied to uplink transmissions located in the UL SB and overlapping with the SSB or the common control channel, such as RO or effective RO, and uplink transmissions located in the UL only time domain unit and overlapping with the SSB or the common control channel, such as RO or effective RO.
[0396] Optionally, the terminal adopts the spatial domain parameters for reception, and the spatial domain parameters are applied to the PDCCH or PDSCH located in the DL SB.
[0397] Optionally, the terminal adopts the spatial domain parameters for reception, where the spatial domain parameters are applied to a PDCCH or PDSCH located in a DL SB and overlapping with an uplink transmission (such as a RO or an effective RO).
[0398] Optionally, the terminal adopts the spatial domain parameters for reception, and the spatial domain parameters are applied to the PDCCH or PDSCH located in the DL SB and the DL only time domain unit.
[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 and overlapping with the uplink transmission (such as RO or effective RO), and the PDCCH or PDSCH located in the DL only time domain unit and overlapping with the uplink transmission (such as RO or effective RO).
[0400] Optionally, the first uplink resource includes a valid random access opportunity.
[0401] Optionally, the valid RO is determined by the terminal based on the network side device configuration or predefined rules in a random access opportunity configured by the network side device after the terminal obtains the network side device configuration or predefined rules.
[0402] The rule includes one of the following:
