[0001] Cross Reference to Related Applications

[0002] This application claims priority to the Chinese Patent Application No. 202410633912.6, filed on May 21, 2024, and entitled "Information Determination Method, Terminal and First Network Side Device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0059] In order to better understand the embodiments of the present application, the related technologies of the present application are described.

[0060] (1) Cell free network.

[0061] The cell free massive Multiple Input Multiple Output (MIMO) system breaks the concept of cells in the traditional massive MIMO system. A large number of antennas are distributed in a wide area instead of being deployed at the same macro base station, and UEs are also distributed in the wide area. These antennas are called transmit-receive points (TRPs) or access points (APs). In theory, each UE can communicate with each TRP, and with the help of a forward network and a central processing unit (CPU), a large number of geographically distributed TRPs can jointly serve a small number of UEs, and the CPU uses channel statistical information for joint detection. It is expected to be applied to the next generation of indoor and hotspot coverage scenarios, such as smart factories, train stations, shopping centers, stadiums, subways, hospitals, community centers, or university campuses, etc.

[0062] Traditional deployment of multiple TRP (mTRP) network usually adopts a Time Division Duplexing (TDD) transmission mode, and assumes that the uplink and downlink time slot configurations of each TRP in the network are the same. The network side device can determine the uplink and downlink time slot configuration parameters according to the overall uplink and downlink traffic demand in the entire cell free network.

[0063] (2) Sub-band full duplex (SBFD).

[0064] SBFD means that uplink transmission and downlink transmission can be performed at different frequency domain positions at the same time. To avoid interference between uplink and downlink, a certain guard band (Guard Band) can be left between the frequency domain positions corresponding to different transmission directions (corresponding to duplex sub-band). Terminal side half duplex, that is, consistent with TDD, at the same time, only uplink transmission or downlink transmission can be performed, and both cannot be performed at the same time. It can be understood that in this duplex mode, the uplink transmission and downlink transmission of the network side at the same time can only be for different terminals, that is, the terminal is still half duplex.

[0065] FIG. 2 shows a schematic diagram of a flexible duplex mode.

[0066] As shown in FIG. 2, the network side device divides the frequency domain of a single carrier into three duplex sub-bands in a part of the downlink symbol, wherein the two sides of the carrier are downlink duplex sub-bands, and the center is an uplink duplex sub-band, so as to reduce the interference caused to adjacent carriers. In the third time slot, UE1 performs uplink transmission in a half duplex mode, and UE2 performs downlink reception in a half duplex mode.

[0067] R18 sub-band full duplex assumes that uplink and downlink use different sub-bands of a carrier in the same time period; in a cell free network, it is assumed that different TRPs work on the same sub-band / frequency resource.

[0068] (3) New Radio (NR) Time Division Duplexing (TDD) parameter configuration.

[0069] 1. Common TDD configuration.

[0070] In the 5th generation mobile communication technology (5-Generation, 5G) / NR, the 3rd Generation Partnership Project (3GPP) introduces several parameters to achieve more flexible "uplink-downlink subframe ratio" through parameter setting. High-level signaling provides TDD-UL-DL-confgcommon through Synchronization Signal / PBCH Block (SSB) 1 or ServingCellConfigCommon, which contains configuration time dedicated to UL, DL or Flexible.

[0071] As shown in FIG. 3, TDD-UL-DL-configcommon contains the following parameters:

[0072] referenceSubcarrierSpacing: for dynamic TDD configuration, slot format indication-Radio Network Temporary Identifier (SFI-RNTI) scheduled by Downlink Control Information (DCI) will use the reference subcarrier spacing (SCS) to calculate the duration of the scheduled time slot.

[0073] dl-UL-TransmissionPeriodicity: defines the period of the DL-UL transmission model, for example, 0.5ms, 0.625ms, 1ms, 1.25ms, 2ms, 2.5ms, 5ms, 10ms. That is, before defining how many time slots are occupied by DL / UL respectively, the total time range occupied by DL / UL is first defined, and then the number of time slots occupied by uplink or DL is defined.

[0074] nrofDownlinkSlots: defines how many time slots are occupied by DL within the entire dl-UL-TransmissionPeriodicity.

[0075] nrofUplinkSlots: defines how many time slots are occupied by UL within the entire dl-UL-TransmissionPeriodicity.

[0076] nrofUplinkSymbols: defines how many symbols are occupied by UL within the entire dl-UL-TransmissionPeriodicity.

[0077] nrofDownlinkSymbols: defines how many symbols are occupied by DL within the dl-UL-TransmissionPeriodicity.

[0078] For example, these parameters can be defined by the following elements:

[0079] TDD-UL-DL-confgcommon: = SEQUENCE {

[0080] referenceSubcarrierSpacing SubcarrierSpacing,

[0081] dl-UL-TransmissionPeriodicity ENUMERATED [ms0p5, ms0p625, ms1, ms1p25, ms2, ms2p5, ms5, ms10] OPTIONAL,

[0082] nrofDownlinkSlots INTEGER (0..maxNrofSlots) OPTIONAL,

[0083] nrofDownlinkSymbols INTEGER (0..maxNrofSymbols-1) OPTIONAL,

[0084] nrofUplinkSlots INTEGER (0..maxNrofSlots) OPTIONAL,

[0085] nrofUplinkSymbols INTEGER (0..maxNrofSymbols-1) OPTIONAL

[0086] }.

[0087] Based on the above data structure, it can be seen that although 5G / NR does not define "uplink-downlink subframe ratio", through the setting of these parameters, it actually stipulates how long the total time length of uplink transmission and downlink transmission occupies in a TDD cell.

[0088] 2. Dedicated semi-static TDD configuration.

[0089] As mentioned above, TDD-UL-DL-ConfigCommon can configure a certain number of UL and DL slots in a period of time. Therefore, the remaining slots under TDD-UL-DL-ConfigCommon in each period of time can be considered flexible. With the help of TDD-UL-DL-ConfigDedicated, the network can configure these flexible slots for a specific terminal. TDD-UL-DL-ConfigDedicated contains a set of slot configurations, each of which corresponds to a slot format. Such slot configuration can be in the form of all DL (D), all UL (U), or flexible DL / UL (F). If it is all DL or UL, all 14 OFDM symbols in this slot are unidirectional. If it is a flexible configuration, there is a nrofDownlinkSymbols parameter indicating the number of downlink symbols of the slot, and a nrofUplinkSymbols parameter indicating the number of uplink symbols of the slot.

[0090] The following gives an example of slot format (format) by Table 1.

[0091] Table 1

[0092] It should be understood that Table 1 is only an example and should not be understood as a limitation of the present application, for example, in other alternative embodiments, the correspondence between the index of the slot format and its specific format can also be adjusted as needed, which is not specifically limited by the present application.

[0093] Semi-static TDD configuration is a method that allows a certain degree of flexibility in UL / DL TDD allocation, and its advantage is that the configuration can be specific to UE, thereby achieving traffic adaptation.

[0094] 3. Dynamic TDD configuration.

[0095] Dynamic TDD configuration is only valid for flexible slots. If the slot is not configured, it will be considered flexible and a dynamic TDD system can be implemented. Using DCI format 2_0 scheduling, dynamic TDD configuration can be achieved in a short time. The DCI message is accompanied by a cyclic redundancy check (Cyclic Redundancy Check, CRC) encrypted with SFI-RNTI and can be sent to a group of terminals to inform the slot format (slot-format) of TDD operation as shown in Table 1 above.

[0096] (4) Random access procedure.

[0097] The random access procedure includes a contention-based random access procedure and a non-contention-based random access procedure.

[0098] In the contention-based 4-step random access procedure, the UE first sends a message 1 (Msg1) containing a preamble to the network; after the network detects the preamble, the network sends a Msg2 / Random Access Response (RAR) message containing the number of the detected preamble and uplink radio resources allocated to the UE for sending a Msg3; after the UE receives the Msg2, the UE confirms that at least one of the numbers of the preambles carried in the Msg2 is consistent with the number of the preamble sent by the UE, and then sends a Msg3 containing contention resolution information according to the indicated resources in the RAR; after the network receives the Msg3, the network sends a Msg4 containing contention resolution information; after the UE receives the Msg4, the UE confirms that the resolution information is consistent with the information sent by the UE in the Msg3, and the 4-step random access is completed.

[0099] The network includes uplink grant (UL grant) information in the RAR for indicating Msg3 physical uplink shared channel (PUSCH) scheduling information, and includes random access preamble identifier (RAPID), temporal cell radio network temporary identifier (TC-RNTI), timing advance (TA), and the like. If the network does not receive the Msg3 PUSCH, the network can schedule retransmission of the Msg3 PUSCH in a physical downlink control channel (PDCCH) scrambled by the TC-RNTI.

[0100] For the contention-based random access procedure, different UEs randomly select a preamble for transmission. Thus, different UEs can select the same preamble for transmission on the same time-frequency radio resource, which can be understood as a preamble collision of UEs. In this case, different UEs can receive the same RAR, and then the different UEs can perform Msg3 PUSCH transmission according to the scheduling information in the UL grant in the RAR. The network can only decode one PUSCH (containing contention resolution information) sent by a UE on one Msg3 PUSCH scheduling resource. Therefore, the network can include the contention resolution information received in Msg3 in Msg4. If the contention resolution information in Msg4 received by the UE matches the contention resolution information sent by the UE in Msg3 PUSCH, the UE can consider that the contention resolution is successful. If the contention resolution information in Msg4 received by the UE does not match the contention resolution information sent by the UE in Msg3 PUSCH, the UE considers that the contention resolution is unsuccessful.

[0101] If the contention resolution is unsuccessful, the UE reselects a random access channel (RACH) transmission resource and performs PRACH transmission for the next random access attempt.

[0102] In NR Rel-16, a two-step random access procedure (2-step RACH) is introduced, which is also called a Type-2 random access procedure. The first step is that the UE sends MsgA to the network side device. After the network side device receives MsgA, the network side device sends MsgB to the UE. If the UE does not receive MsgB within a certain time, the UE increments a counter that counts the number of times of sending MsgA and re-sends MsgA. If the counter that counts the number of times of sending MsgA reaches a certain threshold, the UE switches from the 2-step random access procedure to the 4-step random access procedure. The random access message MsgA includes a MsgA preamble part and a MsgA PUSCH part. The MsgA preamble part is sent on a PRACH opportunity for 2-step RACH, and the MsgA PUSCH part is sent on a MsgA PUSCH resource associated with the MsgA preamble and the PRACH opportunity. The MsgA PUSCH resource is a set of PUSCH resources configured relative to each PRACH slot, including time-frequency resources and demodulation reference signal (DMRS) resources.

[0103] (5) Selection of random access resources.

[0104] In NR, a cell can configure multiple Frequency Division Duplexing (FDD) PRACH occasions (ROs) in one time domain location of a transmission PRACH.

[0105] The number of FDM PRACH occasions that can be performed at one time can be {1, 2, 4, 8}. For example, as shown in FIG. 4, there are 8 PRACH occasions distributed in different frequencies at one time.

[0106] A preamble can only be transmitted on the time domain resource (i.e., RO) configured by the parameter PRACHConfigurationIndex, and the 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 higher layer parameter PRACH-FDM. In the initial access, the PRACH frequency domain resource n RA The ROs in the initial active uplink bandwidth part are numbered in ascending order from the lowest frequency RO, otherwise, the PRACH frequency domain resource n RA The ROs in the active uplink bandwidth part are numbered in ascending order from the lowest frequency RO. For example, as shown in FIG. 4, the ROs are numbered in ascending order from low to high frequencies as RO#0-RO#7.

[0107] In NR, there is an association relationship between RO and the actual transmitted synchronization signal and / or physical broadcast channel block (SSB). One SSB can be associated with multiple ROs, and multiple SSBs can be associated with one RO (in this case, different SSBs correspond to different preambles). Generally, the network device can use different beams to transmit different SSBs, and the corresponding UE transmits a preamble on the RO associated with the SSB, so that the UE selects the RO / “RO and preamble combination” associated with the SSB with good signal strength according to the received downlink beam / SSB strength, and transmits 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 transmits Msg2 on the downlink beam corresponding to the SSB to ensure the reception quality of the downlink signal.

[0108] Taking FIG. 4 as an example, the number of ROs of FDM at one time is 8, the number of actually transmitted SSBs is 4, that is, SSB#0, SSB#1, SSB#2, and SSB#3, and each SSB is associated with 2 ROs. If the UE determines to send PRACH / Msg1 / preamble on the RO corresponding to SSB#0, the UE selects one of RO#0 and RO#1 to send PRACH.

[0109] Taking FIG. 5 as an example, the number of ROs of FDM at one time is 2, the number of actually transmitted SSBs is 8, that is, SSB#0, SSB#1,..., and SSB#7, and each 2 SSBs are associated with 1 RO. When multiple SSBs share one RO, the preamble set associated with the multiple SSBs is different, that is, the same preamble cannot belong to the preamble set associated with different SSBs at the same time. Taking RO#0 in FIG. 5 as an example, it has 60 preambles associated with SSBs, in which the preambles with indexes 0-29 are associated with SSB#0, and the preambles with indexes 30-59 are associated with SSB#1.

[0110] It is worth noting that one square in FIG. 4 and FIG. 5 represents one RO, not SSB, in which the target SSB refers to which SSB / SSBs are associated with the RO.

[0111] Before the UE sends PRACH, resource selection is performed first. First, a SSB with a reference signal receiving power (RSRP) higher than a threshold is selected according to the received beam / SSB. If there are multiple SSBs with an RSRP higher than the threshold, the terminal can select any SSB with an RSRP higher than the threshold. When there is no SSB with an RSRP higher than the threshold, the UE selects a SSB based on implementation.

[0112] Based on network (NW) configuration, the UE obtains the correspondence between SSB and RO. After selecting a SSB, the RO corresponding to the selected SSB is used as the RO for sending PRACH / preamble. If the selected SSB is associated with multiple ROs, the terminal can select one of the ROs to send PRACH / preamble.

[0113] (6) PRACH power control.

[0114] The initial transmission power of the UE is first related to two factors: the initial reception power (sensitivity) expected by the base station and the path loss between the base station and the UE. The base station informs the UE of the initial reception power and the reference signal transmission power in advance, and the UE combines the actual measured reference signal reception power to calculate the path loss and the initial transmission power. The path loss is the reference signal transmission power minus the reference signal reception power, and the initial transmission power is equal to the initial reception power of the base station plus the path loss.

[0115] Wherein, the initial reception power is the preamble initial received target power in long term evolution (LTE) and the preamble received target power in NR. The reference signal transmission power is the reference signal power in LTE and the SSB power (ss PBCH-Block Power) and the synchronization signal power control offset (power Control Offset SS) in NR. The synchronization signal power control offset can be used for channel state information reference signal (CSI-RS).

[0116] In NR, the cell reference signal (CRS) is cancelled, and the reference signal measured by the UE is SSB or CSI-RS to reduce the always-on signal overhead. In LTE, the path loss is denoted as PL c In NR, the concept of bandwidth part (BWP) is introduced, and the path loss is denoted as PL b,f,c b represents the BWP, f represents the carrier, and c represents the cell.

[0117] In NR, the mechanism of Msg1 power boosting is similar to that of LTE, but there are slight differences. In NR, the RO and SSB beam associated with the UE sending Msg1 are related. If the UE reselects the random access (RA) resource, selects the same SSB beam or CSI-RS beam (and does not receive a notification to suspend power boosting from the bottom layer), the retransmission of Msg1 will boost the transmission power. If the UE selects a different SSB beam or CSI-RS beam, the transmission power will not be boosted (this time).

[0118] The preamble signal of PRACH is configured with P PRACH,targetIf the PRACH transmitted according to the configuration is not received with RAR, the UE performs power ramping until the power reaches P CMAX or the PRACH is received with RAR.

[0119] The information determination method provided by the embodiments of the present application will be described in detail below in combination with the drawings, through some embodiments and application scenarios.

[0120] FIG. 6 is a schematic flowchart of the information determination method 210 according to an embodiment of the present application.

[0121] As shown in FIG. 6, the information determination method 210 can include at least part of the following contents:

[0122] S211, the terminal determines at least one of the following according to at least one first reference signal of the first network side device:

[0123] a first duplex configuration associated with the at least one first reference signal;

[0124] whether at least one transmission opportunity is valid;

[0125] an available time unit of a first uplink channel.

[0126] Exemplarily, the terminal determines the first duplex configuration associated with the at least one first reference signal based on the at least one first reference signal, that is, the first duplex configuration is a duplex configuration of the first network side device.

[0127] Exemplarily, the terminal determines whether the at least one transmission opportunity is valid based on the at least one first reference signal. That is, the terminal can determine the validity of the at least one transmission opportunity based on the at least one first reference signal. For example, the terminal can determine the validity of the at least one transmission opportunity based on the at least one first reference signal and a duplex configuration of the terminal. The duplex configuration of the terminal can include at least one of the following: the first duplex configuration, a duplex configuration associated with a reference signal of another network side device.

[0128] Exemplarily, the terminal determines the available time unit of the first uplink channel based on the at least one first reference signal. For example, the terminal can determine the available time unit of the first uplink channel based on the at least one first reference signal and a duplex configuration of the terminal. The duplex configuration of the terminal can include at least one of the following: the first duplex configuration, a duplex configuration associated with a reference signal of another network side device.

[0129] Exemplarily, the first reference signal can be a downlink reference signal, including but not limited to: a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a synchronization signal and / or a physical broadcast channel block (SSB), a channel state information reference signal (CSI-RS), a tracking reference signal (TRS), or a row demodulation reference signal (DMRS), etc.

[0130] Exemplarily, the first duplex configuration can be a time domain duplex configuration, a frequency domain duplex configuration, or other duplex configurations, which are not limited in the present application. The time domain duplex configuration can be a time slot duplex configuration, for example, TDD, and the frequency domain duplex configuration can be an SBFD configuration or an FDD configuration, and the SBFD configuration can also be referred to as flexible duplex (XDD).

[0131] Exemplarily, the first duplex configuration can be a half duplex configuration / full duplex configuration. Correspondingly, the terminal and the first network side device can be devices supporting half duplex / full duplex capability.

[0132] Exemplarily, the at least one transmission opportunity includes at least one of: a physical random access channel transmission opportunity (RO), a physical uplink shared channel opportunity (PO). The RO includes but is not limited to: a 4-step RACH opportunity and a 2-step RACH opportunity. The PO includes but is not limited to: a configured-grant (CG) based PUSCH opportunity, a MsgA PUSCH opportunity, a Msg3 PUSCH opportunity, and a Msg5 PUSCH opportunity.

[0133] Exemplarily, the first uplink channel includes at least one of: a Msg3 PUSCH, a TB processing over multiple slots (TBoMS) PUSCH, a repeated transmission PUSCH, and a repeated transmission PDCCH.

[0134] For example, the available time unit indicates a time unit available for transmitting the first uplink channel.

[0135] For example, the available time unit includes at least one of a radio frame, a half frame, a subframe, a time slot, an Orthogonal Frequency Division Multiplexing (OFDM) symbol, or other metric units representing time length. Hereinafter, a downlink time unit refers to a time unit in which all subbands of the time unit are DL, and an uplink time unit refers to a time unit in which all subbands of the time unit are UL. Similarly, a flexible time in the present disclosure can include one or more flexible time units.

[0136] In the embodiments of the present disclosure, the terminal determines the first duplex configuration associated with the at least one first reference signal according to the at least one first reference signal of the first network side device, avoids associating the duplex configuration with the cell, can improve the flexibility of the duplex configuration and the utilization rate of the network resource, and further can improve the communication performance of the terminal. Correspondingly, the terminal determines whether the at least one transmission opportunity is valid or the available time unit of the first uplink channel according to the at least one first reference signal of the first network side device, which is equivalent to, when determining whether the at least one transmission opportunity is valid or the available time unit of the first uplink channel, the terminal can not focus on other reference signals. Not only can the flexibility of the resource validity judgment or the available resource judgment be improved, but also the accuracy of the resource validity judgment or the available resource judgment can be improved, and further the communication performance of the terminal can be improved.

[0137] In a full-duplex (FD) cell free architecture, the first network-side device can be a first TRP, and the terminal can determine a duplex configuration associated with the reference signal of the first TRP based on the reference signal of the first TRP. In other words, the duplex configuration is associated with the reference signal of the TRP, so different TRPs can be associated with different duplex configurations, and uplink and downlink data transmission can be performed on the same time-frequency domain resource. Moreover, in this architecture, the duplex configuration of the TRP is fixed, and a more flexible UE-oriented full-duplex configuration, such as a full-duplex slot configuration, can be achieved by controlling the UE and different TRPs to perform uplink transmission or downlink reception, and the corresponding uplink transmission quasi-co-located (QCL) relationship and downlink transmission transmission configuration indication (TCI). In addition, the duplex configuration is associated with the reference signal of the TRP. For example, in a scenario where the terminal supports connection with at least two TRPs (or TRP clusters), the duplex mode related information configuration of different TRPs (or TRP clusters) can be different. In this case, the terminal can meet the uplink and downlink transmission requirements of any proportion by connecting TRPs with different duplex configurations. The TRP can improve network resource utilization and reduce implementation complexity, thereby helping to reserve more network resources for more comprehensive interference measurement, joint optimization and transmission control, to improve the communication performance of the terminal.

[0138] In a cell free network, the duplex mode configuration (such as uplink and downlink time slot ratio) of each TRP / AP cluster can be different due to the uplink and downlink traffic demand. The terminal needs to consider the different duplex configurations of multiple TRPs supported by the cell free network. For example, the terminal can also have good channel quality with multiple TRPs, i.e., the terminal can also perform data transmission with multiple TRPs. In this case, the terminal needs to determine its own duplex configuration and the uplink and downlink resources that can be used in the cell free network according to the duplex configuration of the currently connected TRP, and then communicate with the corresponding TRP.

[0139] Based on this, the network-side device configures the duplex configuration associated with the reference signal of the terminal and different TRPs to meet the uplink and downlink data transmission requirements of any proportion of the terminal. Similarly, the network-side device configures the transmission opportunity, such as RO / PO, associated with the reference signal of the terminal and different TRPs to improve the configuration flexibility of the transmission opportunity.

[0140] In addition, for an idle / inactive terminal or a terminal in a random access stage, the terminal can determine the duplex configuration of the terminal after obtaining different duplex configurations (e.g., duplex configurations associated with reference signals of different TRPs), and determine the validity of the transmission opportunity based on the duplex configuration of the terminal. For example, the terminal can determine the validity of the RO / PO based on the duplex configuration of the terminal. Similarly, the terminal can determine the available time unit of the uplink channel based on the duplex configuration of the terminal after obtaining different duplex configurations (e.g., duplex configurations associated with reference signals of different TRPs). For example, the terminal can determine the available time unit of the PUSCH / PUCCH based on the duplex configuration of the terminal, such as the available time slot of the PUSCH / PUCCH.

[0141] It should be understood that the valid RO / PO referred to in the present application can refer to resources that can be used for corresponding channel signal transmission, or resources that are considered / defined as valid. For example, the terminal can consider that the RO / PO that does not conflict with the duplex configuration of one TRP is a valid RO / PO. In addition, the SSB and SS / PBCH block referred to in the present application can be used interchangeably, or can be other names, which can refer to any signal containing at least part of the synchronization signal, broadcast signal, or other downlink broadcast signal.

[0142] Of course, in other alternative embodiments, the TRP can also be associated with the duplex configuration, i.e., the terminal determines at least one of the following based on the first network side device: the duplex configuration associated with the first network side device, whether the at least one transmission opportunity is valid, and the available time unit of the first uplink channel. The related scheme can refer to the scheme of associating the reference signal of the TRP with the duplex configuration, and to avoid repetition, it will not be described here.

[0143] In some embodiments, in the case where the at least one first reference signal and other reference signals share a resource set, the first resource of the at least one first reference signal is associated with the first duplex configuration, and the resource type of the first resource is different from the resource type of the shared resource set, and the resource type includes at least one of the following: time domain resource, frequency domain resource, space domain resource, and code domain resource.

[0144] Exemplarily, in a case that the at least one first reference signal and other reference signals share a set of time domain resources, frequency domain resources, code domain resources, or spatial domain resources of the at least one first reference signal are associated with the first duplex configuration. In a case that the at least one first reference signal and other reference signals share a set of time domain resources, code domain resources, or spatial domain resources of the at least one first reference signal are associated with the first duplex configuration. In a case that the at least one first reference signal and other reference signals share a set of time-frequency domain resources, spatial domain resources or code domain resources of the at least one first reference signal are associated with the first duplex configuration.

[0145] For example, assuming that the at least one first reference signal is {SSB#1, SSB#2, SSB#3, SSB#4} and other reference signals are {SSB#5, SSB#6, SSB#7, SSB#8}, the at least one first reference signal and other reference signals share a set of time-frequency domain resources, in this case, {SSB#1, SSB#2, SSB#3, SSB#4} and {SSB#5, SSB#6, SSB#7, SSB#8} can be distinguished by code domain resources or spatial domain resources.

[0146] Exemplarily, the terminal obtains the associated first duplex configuration through at least one first reference signal sent by the first network side device. The first reference signal includes a synchronization signal (such as SSB), CSI-RS, TRS, DMRS, and the like. The first duplex configuration includes a TDD configuration, an FDD configuration, an XDD configuration / SBFD configuration.

[0147] Exemplarily, the association between the at least one first reference signal and the first duplex configuration of the first network side device includes:

[0148] Method one:

[0149] The at least one first reference signal is associated with the first duplex configuration as a reference signal group (for example, according to a certain rule / order). Different reference signal groups are associated with different duplex configurations.

[0150] For example, the first reference signal is SSB, the terminal is configured with N SSB groups, where the identity (ID) of each SSB group is associated with one duplex configuration, and the IDs of different SSB groups are associated with different duplex configurations or different TRPs. Assuming N = 2, the SSB groups configured by the first network side device are SSB group #1 and SSB group #2 respectively, then SSB group #1 can be associated with duplex configuration 1, and SSB group #2 can be associated with duplex configuration 2. For example, SSB group #1 is {SSB #1, SSB #2, SSB #3, SSB #4}, and SSB group #2 is {SSB #5, SSB #6, SSB #7, SSB #8}. For example, in the case where SSB group #1 and SSB group #2 share a set of time-frequency domain resources, the spatial domain resources or code domain resources of SSB group #1 can be associated with duplex configuration 1, and the spatial domain resources or code domain resources of SSB group #2 can be associated with duplex configuration 2.

[0151] Method two:

[0152] Without introducing the concept of reference signal group, the index of the at least one first reference signal (for example, in a certain rule / order) is associated with the first duplex configuration. The reference signal index can be directly associated with different duplex configurations. The index of the at least one first reference signal can be indicated by the parameter ssb-PositionsInBurs in SIB1 or ServingCellConfigCommon.

[0153] For example, the first reference signal is SSB, the terminal is configured with N SSBs, and every M SSBs are associated with the same duplex configuration. Assuming that the N SSBs include SSB #1, SSB #2, SSB #3, and SSB #4, for example, N = 4 and M = 1, SSB #1 can be associated with duplex configuration 1, SSB #2 can be associated with duplex configuration 2, SSB #3 can be associated with duplex configuration 3, and SSB #4 can be associated with duplex configuration 4. For example, N = 4 and M = 2, SSB #1 and SSB #2 can be associated with duplex configuration 1, and SSB #3 and SSB #4 can be associated with duplex configuration 2.

[0154] In some embodiments, the first duplex configuration includes a common duplex configuration, and the common duplex configuration includes at least one of the following:

[0155] The number of first downlink time units associated with the at least one first reference signal;

[0156] The number of first uplink time units associated with the at least one first reference signal;

[0157] The number of second downlink time units associated with the at least one first reference signal;

[0158] a number of second uplink time units associated with the at least one first reference signal;

[0159] at least one time unit associated with the at least one first reference signal;

[0160] a downlink frequency domain range on the at least one time unit associated with the at least one first reference signal;

[0161] an uplink frequency domain range on the at least one time unit associated with the at least one first reference signal.

[0162] Exemplarily, the first network-side device configures the terminal with a common duplex configuration associated with the at least one first reference signal, which can be carried in SIB1 or in ServingCellConfigCommon field.

[0163] Exemplarily, the uplink time unit or the downlink time unit comprises at least one of the following: radio frame, half frame, subframe, slot, OFDM symbol, or other metric unit representing time length. The time length of the first uplink time unit is greater than or smaller than the time length of the second uplink time unit, and the time length of the first downlink time unit is greater than or equal to the time length of the second downlink time unit. For example, the first uplink time unit is an uplink slot, and the second uplink time unit is an uplink symbol. The first downlink time unit is a downlink slot, and the second downlink time unit is a downlink symbol.

[0164] Exemplarily, the time unit in the at least one time unit comprises at least one of the following: radio frame, half frame, subframe, slot, OFDM symbol, or other metric unit representing time length. The at least one time unit can comprise at least one of the following: downlink time unit, uplink time unit or flexible time unit.

[0165] It should be noted that, for TDD, the uplink time unit refers to that the symbols in the time unit are all uplink symbols, the downlink time unit refers to that the symbols in the time unit are all downlink symbols, and the flexible time unit refers to that the symbols in the time unit are flexible, i.e., subsequent configuration can be used for uplink or downlink. For FDD or SBFD, the uplink time unit refers to that the frequency domain range in the time unit is all uplink frequency domain range, the downlink time unit refers to that the frequency domain range in the time unit is all downlink frequency domain range, and the flexible time unit refers to that the frequency domain range in the time unit is flexible frequency domain range, i.e., subsequent configuration can be used for uplink or downlink. The downlink frequency domain range on the at least one time unit and the uplink frequency domain range on the at least one time unit can be different subbands on one carrier.

[0166] Exemplarily, the common duplex configuration comprises a common TDD configuration or a common SBFD configuration.

[0167] Exemplarily, the common TDD configuration comprises at least one of: a number of first downlink time units associated with the at least one first reference signal; a number of first uplink time units associated with the at least one first reference signal; a number of second downlink time units associated with the at least one first reference signal; a number of second uplink time units associated with the at least one first reference signal. The common SBFD configuration comprises at least one of: at least one time unit associated with the at least one first reference signal; a downlink frequency domain range on the at least one time unit associated with the at least one first reference signal; an uplink frequency domain range on the at least one time unit associated with the at least one first reference signal.

[0168] For example, the common duplex configuration associated with the at least one first reference signal can be a common TDD configuration of NR, which can be TDD-UL-DL-configcommon associated with the at least one first reference signal. The TDD-UL-DL-configcommon associated with the at least one first reference signal comprises at least one of:

[0169] nrofDownlinkSlots: how many slots are occupied by DL within the whole dl-UL-TransmissionPeriodicity;

[0170] nrofUplinkSlots: how many slots are occupied by UL within the whole dl-UL-TransmissionPeriodicity;

[0171] nrofUplinkSymbols: how many symbols are occupied by UL within the whole dl-UL-TransmissionPeriodicity;

[0172] nrofDownlinkSymbols: how many symbols are occupied by DL within the whole dl-UL-TransmissionPeriodicity.

[0173] It should be noted that the TDD-UL-DL-configcommon associated with the at least one first reference signal can be a TDD-UL-DL-configcommon associated with a group ID of a reference signal group in which the at least one first reference signal is located, or can be a TDD-UL-DL-configcommon associated with an index of the at least one first reference signal. Different reference signal groups are associated with different TDD-UL-DL-configcommon, or the indexes of one or more reference signals (corresponding to the same network side device) are associated with the same TDD-UL-DL-configcommon.

[0174] For another example, the common duplex configuration associated with the at least one first reference signal can be a common SBFD configuration, and the common SBFD configuration includes at least one of the following:

[0175] at least one time unit associated with the at least one first reference signal;

[0176] a downlink frequency domain range in the at least one time unit associated with the at least one first reference signal;

[0177] an uplink frequency domain range in the at least one time unit associated with the at least one first reference signal.

[0178] It should be noted that the SBFD configuration associated with the at least one first reference signal can be a SBFD configuration associated with a group ID of a reference signal group in which the at least one first reference signal is located, or can be a SBFD configuration associated with an index of the at least one first reference signal. Different reference signal groups are associated with different SBFD configurations, or the indexes of one or more reference signals (corresponding to the same network side device) are associated with the same SBFD configuration.

[0179] In some embodiments, the first duplex configuration includes a configuration of a first flexible time under a common duplex configuration associated with the at least one first reference signal, and the configuration of the first flexible time includes at least one of the following:

[0180] an index of a combination format of a time unit in the first flexible time;

[0181] a number of downlink time units in the first flexible time;

[0182] a number of uplink time units in the first flexible time;

[0183] an index of a combination format of a frequency domain range in the first flexible time;

[0184] a downlink frequency domain range in the first flexible time;

[0185] an uplink frequency domain range in the first flexible time.

[0186] Exemplarily, the configuration of the first flexible time can also be referred to as a semi-static duplex configuration, a dedicated duplex configuration, or a specific duplex configuration. The first flexible time can include one or more time units, and the time units include at least one of the following: a radio frame, a half frame, a subframe, a slot, an OFDM symbol, or other metric units representing time length.

[0187] Exemplarily, the configuration of the first flexible time includes a specific TDD configuration or a specific SBFD configuration.

[0188] Exemplarily, the specific TDD configuration includes at least one of the following: an index of a combination format of a time unit in the first flexible time; a number of downlink time units in the first flexible time; a number of uplink time units in the first flexible time. The specific SBFD configuration includes at least one of the following: an index of a combination format of a frequency domain range in the first flexible time; a downlink frequency domain range in the first flexible time; an uplink frequency domain range in the first flexible time.

[0189] Exemplarily, the index of the combination format of the time unit in the first flexible time can be used to implement a periodic configuration of a frame structure.

[0190] Exemplarily, the combination format of the time unit in the first flexible time refers to a permutation combination format of transmission formats on a plurality of smaller time units (such as symbols) within the time unit. The transmission formats include uplink transmission, downlink transmission, flexible transmission, sub-band full duplex transmission, and the like. For example, the combination format of a slot can refer to a combination format of transmission formats of 14 symbols within the slot. Taking Table 1 as an example, if the index of the combination format of the slot is 20, the permutation combination format of the transmission formats of 14 symbols within the slot is DDFFFFFFFFFFFU.

[0191] Exemplarily, the index of the combination format of the time unit in the first flexible time can be a slot format indicator (SFI) in NR, indicating that a PDCCH monitoring period of slots starting from the SFI is configured according to the SFI.

[0192] Exemplarily, the index of the combination format of the frequency domain range in the first flexible time can be used to implement a periodic configuration of a frame structure.

[0193] Exemplarily, the index of the combination format of the frequency domain range in the first flexible time comprises an index of a combination format of a frequency range in a time unit (e.g., any time unit) in the first flexible time.

[0194] Exemplarily, the combination format of the frequency domain range in the first flexible time refers to an arrangement combination format of a transmission format in a plurality of minimum frequency ranges (e.g., subbands) in the frequency domain range. The transmission format comprises an uplink transmission, a downlink transmission, a flexible transmission, a subband full duplex transmission, and the like. For example, the combination format of the frequency domain range can refer to a combination format of a transmission format of a plurality of subbands in the frequency domain range. For example, for the first time slot, the arrangement combination format of the transmission format of 3 subbands in the frequency domain range is DDD.

[0195] In this embodiment, the first duplex configuration comprises the configuration of the first flexible time in the common duplex configuration associated with the at least one first reference signal, which avoids associating the configuration of the first flexible time in the common duplex configuration with the cell, and can improve the flexibility of the configuration of the first flexible time and the utilization of network resources, and further improve the communication performance of the terminal.

[0196] For example, the configuration of the first flexible time can be a specific TDD configuration of NR, which can be TDD-UL-DL-ConfigDedicated associated with the at least one first reference signal. For example, the TDD-UL-DL-ConfigDedicated associated with the at least one first reference signal can comprise at least one of the following:

[0197] nrofDownlinkSymbols: represents the number of downlink symbols of the first flexible time;

[0198] nrofUplinkSymbols: represents the number of uplink symbols of the first flexible time.

[0199] For another example, the configuration of the first flexible time can be a specific SBFD configuration, which can comprise at least one of the following:

[0200] Downlink subband: represents a downlink frequency domain range in the first flexible time;

[0201] Uplink subband: represents an uplink frequency domain range in the first flexible time.

[0202] In some embodiments, the configuration of the first flexible time is only for the first flexible time; or the configuration of the first flexible time is for the first flexible time and a reference signal associated with a common duplex configuration other than the at least one first reference signal in a signal set to which the at least one first reference signal belongs; or the configuration of the first flexible time is for the first flexible time and a flexible time under a common duplex configuration associated with a reference signal of another network-side device.

[0203] Exemplarily, the configuration of the first flexible time is the specific TDD configuration / specific SBFD configuration, and the application of the specific TDD configuration / specific SBFD configuration includes at least one of the following:

[0204] The specific TDD configuration / specific SBFD configuration needs to be configured under a common duplex configuration associated with the same reference signal (for example, the same reference signal group or the same reference signal index). For example, the specific TDD configuration / specific SBFD configuration associated with SSB group 1 is configured only for the remaining flexible time slots or flexible symbols under the common duplex configuration associated with SSB group 1.

[0205] The specific TDD configuration / specific SBFD configuration needs to be configured under a common duplex configuration associated with all reference signals (for example, all reference signal groups or all reference signal indexes). For example, the specific TDD configuration / specific SBFD configuration associated with SSB group 1 is configured for the remaining flexible time slots and flexible symbols under all common duplex configurations associated with all SSBs (including all SSBs in SSB group 1 and other SSBs).

[0206] The specific TDD configuration / specific SBFD configuration needs to be configured under a common duplex configuration associated with all reference signals in a specific reference signal set, and the specific reference signal set contains the reference signal to which the specific TDD configuration / specific SBFD configuration is associated. For example, the specific TDD configuration / specific SBFD configuration associated with SSB group 1 is configured for the remaining flexible time slots and flexible symbols under all common duplex configurations associated with all SSBs in the same set as SSB group 1.

[0207] It should be noted that only one common duplex configuration (i.e., associated with all reference signals or all TRPs) can be supported, in which case the specific TDD configuration / specific SBFD configuration associated with different reference signal groups or different TRP reference signal indexes is further duplex configured under one common duplex configuration.

[0208] In some embodiments, the first duplex configuration comprises a configuration of a second flexible time under a common duplex configuration of the at least one first reference signal association, the configuration of the second flexible time comprising at least one of:

[0209] an index of a combination format of time units in the second flexible time;

[0210] an index of a combination format of frequency domain ranges on the second flexible time.

[0211] Exemplarily, the index of the combination format of time units in the second flexible time can be used to implement a periodic configuration of frame structure.

[0212] Exemplarily, the combination format of time units in the second flexible time refers to a permutation combination format of transmission formats on a plurality of smaller time units (e.g. symbols) within a time unit. The transmission formats include uplink transmission, downlink transmission, flexible transmission, sub-band full duplex transmission, etc. For example, the combination format of a slot can refer to a combination format of transmission formats of 14 symbols within a slot. Taking Table 1 as an example, if the index of the combination format of a slot is 20, the permutation combination format of transmission formats of 14 symbols within a slot is DDFFFFFFFFFFFU.

[0213] Exemplarily, the index of the combination format of time units in the second flexible time can be a slot format indicator (SFI) in NR, indicating that a PDCCH monitoring period of slots starting from the reception of the SFI is configured according to the SFI.

[0214] Exemplarily, the index of the combination format of frequency domain ranges on the second flexible time can be used to implement a periodic configuration of frame structure.

[0215] Exemplarily, the index of the combination format of frequency domain ranges on the second flexible time comprises an index of a combination format of frequency ranges on a time unit (e.g. any time unit) in the second flexible time.

[0216] Exemplarily, the combination format of frequency domain ranges on the second flexible time refers to a permutation combination format of transmission formats on a plurality of smallest frequency ranges (e.g. sub-bands) within a frequency domain range. The transmission formats include uplink transmission, downlink transmission, flexible transmission, sub-band full duplex transmission, etc. For example, the combination format of a frequency domain range can refer to a combination format of transmission formats of a plurality of sub-bands within a frequency domain range. Taking Figure 2 as an example, for the first slot, the permutation combination format of transmission formats of 3 sub-bands within a frequency domain range is DDD.

[0217] Exemplarily, the configuration of the second flexible time can also be referred to as a dynamic (Dynamics) duplex configuration. The second flexible time can include one or more time units, and the time units include at least one of the following: a radio frame, a half frame, a subframe, a time slot, an OFDM symbol, or other metric units representing time length.

[0218] In this embodiment, the first duplex configuration includes the configuration of the second flexible time in the common duplex configuration associated with the at least one first reference signal, which is equivalent to avoiding associating the configuration of the second flexible time in the common duplex configuration with a cell, thereby improving the flexibility of the configuration of the second flexible time and the utilization rate of network resources, and further improving the communication performance of the terminal.

[0219] Exemplarily, the configuration of the second flexible time includes a dynamic TDD configuration or a dynamic SBFD configuration.

[0220] Exemplarily, the dynamic TDD configuration includes an index of a combination format of a time unit in the second flexible time. The dynamic SBFD configuration includes an index of a combination format of a frequency domain range on the second flexible time.

[0221] For example, the configuration of the second flexible time can be a dynamic TDD configuration of NR, and the first network-side device can configure a slot format indication (SFI) through DCI format 2_0 (format 2_0) of PDCCH. The SFI is used to dynamically indicate an index of a symbol combination format in a flexible time slot in the second flexible time. For details, refer to the format in Table 1 above, which will not be described here.

[0222] For another example, the configuration of the second flexible time can be a dynamic SBFD configuration, and the first network-side device can dynamically indicate an index of a combination format of a frequency domain range on a flexible time slot in the second flexible time through DCI format 2_0 (format 2_0) of PDCCH. For example, the combination of an uplink frequency domain range and a downlink frequency domain range within a flexible time slot and the index of the corresponding combination format can be designed on the frequency domain, which can be used as a configuration table of the uplink and downlink frequency domain ranges. The configuration table includes all combination formats of the frequency domain ranges and the corresponding indexes. For example, the kth combination format in the configuration table is: k d downlink frequency domain ranges, k f flexible frequency domain ranges, and k u uplink frequency domain ranges. Correspondingly, the dynamic SBFD configuration can include an index of the kth combination format.

[0223] In some embodiments, the configuration of the second flexible time is only for the second flexible time unit; or the configuration of the second flexible time is for the flexible time under the common duplex configuration associated with the reference signals other than the at least one first reference signal in the signal set to which the at least one first reference signal belongs; or the configuration of the second flexible time is for the flexible time under the common duplex configuration associated with the reference signals of the second flexible time unit and other network-side devices.

[0224] Exemplarily, the configuration of the second flexible time is the dynamic TDD configuration / dynamic SBFD configuration, and the application of the dynamic TDD configuration / dynamic SBFD configuration includes at least one of the following:

[0225] The dynamic TDD configuration / dynamic SBFD configuration needs to be configured under the common duplex configuration associated with the same reference signal (for example, the same reference signal group or the same reference signal index). For example, the dynamic TDD configuration / dynamic SBFD configuration associated with SSB group 1 is configured only for the remaining flexible time slots or flexible symbols under the common duplex configuration associated with SSB group 1.

[0226] The dynamic TDD configuration / dynamic SBFD configuration needs to be configured under the common duplex configuration associated with all reference signals (for example, all reference signal groups or all reference signal indexes). For example, the dynamic TDD configuration / dynamic SBFD configuration associated with SSB group 1 is configured for the remaining flexible time slots and flexible symbols under all common duplex configurations associated with all SSBs (including all SSBs in SSB group 1 and other SSBs).

[0227] The dynamic TDD configuration / dynamic SBFD configuration needs to be configured under the common duplex configuration associated with all reference signals in a specific reference signal set, which contains the reference signal associated with the dynamic TDD configuration / dynamic SBFD configuration. For example, the dynamic TDD configuration / dynamic SBFD configuration associated with SSB group 1 is configured for the remaining flexible time slots and flexible symbols under all common duplex configurations associated with all SSBs in the same set as SSB group 1.

[0228] It should be noted that only one common duplex configuration (i.e., associated with all reference signals or all TRPs) can be supported, in which case the dynamic TDD configuration / dynamic SBFD configuration associated with different reference signal groups or different TRP reference signal indexes is further duplex configured under one common duplex configuration.

[0229] It should be understood that the first flexible time can be referred to as a semi-static duplex configuration, and the second flexible time can be referred to as a dynamic duplex configuration. The difference between the configuration of the first flexible time and the configuration of the second flexible time also lies in different messages of the bearer configuration, for example, the configuration of the first flexible time is configured in TDD-UL-DL-ConfigDedicated, and the configuration of the second flexible time is configured in DCI format 2_0.

[0230] In some embodiments, the at least one transmission opportunity comprises at least one of:

[0231] at least one first transmission opportunity, at least one second transmission opportunity;

[0232] The at least one first transmission opportunity comprises at least one of:

[0233] The at least one first transmission opportunity associated with the first reference signal;

[0234] The first transmission opportunity in a first common resource set associated with the first signal set;

[0235] The at least one second transmission opportunity comprises at least one of:

[0236] The second transmission opportunity associated with the first signal set;

[0237] The second transmission opportunity in a second common resource set associated with the first signal set;

[0238] The first signal set comprises the at least one first reference signal and at least one second reference signal of the second network side device.

[0239] Exemplarily, the first transmission opportunity is a transmission opportunity for the first network side device, and the second transmission opportunity is a common transmission opportunity for the first network side device and the second network side device. In other words, the first transmission opportunity refers to a transmission opportunity configured for the terminal for communication with the first network side device, and the second transmission opportunity refers to a transmission opportunity configured for the terminal for communication with any of the first network side device and the second network side device.

[0240] In some embodiments, the at least one first transmission opportunity comprises a first transmission opportunity in an uplink resource unit or a flexible resource unit under the first duplex configuration in the first common resource set, or the at least one second transmission opportunity comprises a second transmission opportunity in an uplink resource unit or a flexible resource unit under a duplex configuration associated with the first signal set in the second common resource set.

[0241] Exemplarily, the uplink resource unit is an uplink time unit or an uplink frequency domain range on a flexible time unit. The flexible resource unit is a flexible time unit or a flexible frequency domain range on a flexible time unit.

[0242] Exemplarily, the first common resource set includes a first common RO resource set, and the at least one first transmission opportunity includes a first RO in an uplink resource unit or a flexible resource unit under the first duplex configuration in the first common RO resource set. Alternatively, the second common resource set includes a second common RO resource set, and the at least one second transmission opportunity includes a second RO in an uplink resource unit or a flexible resource unit under a duplex configuration associated with the first signal set in the second common RO resource set.

[0243] Exemplarily, the first common resource set includes a first common PO resource set, and the at least one first transmission opportunity includes a first PO in an uplink resource unit or a flexible resource unit under the first duplex configuration in the first common PO resource set. Alternatively, the second common resource set includes a second common PO resource set, and the at least one second transmission opportunity includes a second PO in an uplink resource unit or a flexible resource unit under a duplex configuration associated with the first signal set in the second common PO resource set.

[0244] The following describes a related scheme that the at least one first transmission opportunity includes at least one first RO, and the at least one second transmission opportunity includes at least one second RO.

[0245] Exemplarily, the at least one first RO includes at least one of the following: a first RO associated with the at least one first reference signal; a first RO in an uplink resource unit or a flexible resource unit under the first duplex configuration in a first common RO resource set associated with the first signal set. The at least one second RO includes at least one of the following: a second RO associated with the first signal set; a second RO in an uplink resource unit or a flexible resource unit under a duplex configuration associated with the first signal set in a second common RO resource set associated with the first signal set. The first signal set includes the at least one first reference signal and at least one second reference signal of the second network side device.

[0246] The following describes a configuration scheme of the first RO.

[0247] The first network-side device directly or indirectly configures the first RO, which indicates the RO associated with the at least one first reference signal, or the first RO indicates a transmission opportunity for sending a PRACH message in a first duplex configuration of the at least one first reference signal in the first common RO resource set.

[0248] Exemplarily, the configuration method of the first RO can include any of the following methods:

[0249] Method one:

[0250] Directly configure the RO resource of each TRP.

[0251] The first network-side device can configure the association relationship between the RO resource and the reference signal of the TRP (for example, the reference signal group of the TRP or the index of the reference signal of the TRP), and accordingly, the terminal can directly determine the RO associated with the at least one first reference signal as the first RO. Of course, the first network-side device can configure the association relationship between the RO resource and the TRP, and accordingly, the terminal can directly determine the RO associated with the first network-side device as the first RO.

[0252] Method two:

[0253] Indirectly configure the first RO by configuring a first common RO resource set.

[0254] After the first network-side device configures the first common RO resource set associated with all reference signals (for example, SSB) to the terminal, the terminal can determine the RO in the uplink resource unit or the flexible resource unit in the first duplex configuration of the at least one first reference signal in the first common RO resource set as the first RO associated with the at least one first reference signal.

[0255] It can be understood that the first RO in the downlink resource unit is an invalid RO, and the first network-side device can dynamically adjust the activation (that is, the valid RO) and deactivation (that is, the invalid RO) of the first RO through different duplex configurations. Specifically, a specific duplex configuration or a dynamic duplex configuration can be used to configure the RO of different TRPs.

[0256] The configuration scheme of the second RO is described below.

[0257] The first network-side device directly or indirectly configures a second RO, where the second RO refers to an RO associated with a first signal set (including at least one second reference signal of the first network-side device and at least one second reference signal of the second network-side device), or the second RO refers to a transmission opportunity for sending a PRACH message in a duplex configuration (for example, including a first duplex configuration associated with the at least one first reference signal and a duplex configuration associated with the at least one second reference signal of the second network-side device) of a second common RO resource set associated with the first signal set.

[0258] Exemplarily, the configuration method of the second RO can include any of the following methods:

[0259] Method one:

[0260] Directly configure RO resources of each TRP set.

[0261] The first network-side device can configure an association relationship between RO resources and a reference signal set (for example, a reference signal group of a TRP set or an index of a reference signal of a TRP set), and accordingly, the terminal can directly determine the RO associated with the first signal set to which the at least one second reference signal belongs as the second RO. Of course, the first network-side device can configure an association relationship between RO resources and a TRP set, and accordingly, the terminal can directly determine the RO associated with the set to which the first network-side device belongs as the second RO.

[0262] Method two:

[0263] Indirectly configure the second RO by configuring a second common RO resource set.

[0264] After the first network-side device configures the second common RO resource set associated with all reference signals (for example, SSBs) to the terminal, the terminal can determine, as the second RO associated with the at least one second reference signal, an RO in an uplink resource unit or a flexible resource unit in a duplex configuration (for example, including a first duplex configuration associated with the at least one first reference signal and a duplex configuration associated with the at least one second reference signal of the second network-side device) associated with the first signal set to which the at least one first reference signal belongs in the second common RO resource set.

[0265] It can be understood that the second RO in a downlink resource unit is an invalid RO, and the first network-side device can dynamically adjust the activation (that is, the valid RO) and deactivation (that is, the invalid RO) of the second RO through different duplex configurations. Specifically, a specific duplex configuration or a dynamic duplex configuration can be used to configure ROs of different TRPs.

[0266] From the above, the first network side device can configure the terminal with a first RO associated with the at least one first reference signal, or a first common RO resource set associated with the first signal set, or the first network side device can configure the terminal with a second RO associated with the first signal set, or a second common RO resource set associated with the first signal set. The first signal set includes the at least one first reference signal and at least one second reference signal of a second network side device.

[0267] In other words, for the first RO or the second RO, the first network side device can configure the terminal with a mapping relationship between a reference signal and an RO. For the first common RO resource set or the second common RO resource set, the first network side device can configure the terminal with a mapping relationship between a reference signal and a common RO resource set. Specifically, the first network side device can configure the terminal with the mapping relationship in any of the following manners:

[0268] Manner one:

[0269] First, determine the validity of the RO, and then establish the mapping relationship between the RO and the reference signal. For example, the reference signal can be associated with the RO in ascending order of preamble index / frequency domain resource index / time domain resource index.

[0270] Manner two:

[0271] First, associate the reference signal with the common RO resource set, and then determine the validity of the RO. For example, the reference signal can be associated with the common RO resource set in ascending order of preamble index / frequency domain resource index / time domain resource index. The terminal obtains a first duplex configuration associated with the at least one first reference signal through system information associated with the SSB, and then determines the validity of the first RO based on the first duplex configuration. Alternatively, the terminal obtains a duplex configuration associated with the first signal set, and then selects a valid second RO based on the duplex configuration associated with the first signal set.

[0272] The first RO and the second RO will be described below in conjunction with Table 2.

[0273] Table 2

[0274] As shown in Table 2, the TRP1 TDD configuration is DDDSU, the TRP2 TDD configuration is DSUUU, the first common RO resource set is RO{#1, #3, #5}, the second common RO resource set is RO{#2, #4, #6}, the first RO of TRP1 (e.g., SSB#1) is RO{#5}, and the first RO of TRP2 (e.g., SSB#2) is RO{#1, #3, #5}. The second RO resource of TRP1 and TRP2 (e.g., SSB set {SSB#1, SSB#2}) is RO{#6}.

[0275] It should be noted that the RO configuration in Table 2 can represent the relative position of the RO in a TDD cycle. For example, RO#1 and RO#2 can be ROs in different TDD cycles, but both are located in the third time slot of a TDD cycle. The first common RO resource set and the second common RO resource set can be completely non-overlapping, partially overlapping, completely overlapping, or even non-overlapping.

[0276] The following describes the related scheme that the at least one first transmission opportunity includes at least one first PO, and the at least one second transmission opportunity includes at least one second PO.

[0277] Exemplarily, the at least one first PO can include at least one of the following: a first PO associated with the at least one first reference signal; and a first PO in an uplink resource unit or a flexible resource unit in the first duplex configuration in a first common PO resource set associated with the first signal set. The at least one second PO can include at least one of the following: a second PO associated with the first signal set; and a second PO in an uplink resource unit or a flexible resource unit in the duplex configuration associated with the first signal set in a second common PO resource set associated with the first signal set. The first signal set includes the at least one first reference signal and at least one second reference signal of the second network side device.

[0278] The following describes the configuration scheme of the first PO.

[0279] The first network side device directly or indirectly configures the first PO, which indicates a PO associated with the at least one first reference signal, or the first PO indicates a transmission opportunity for transmitting a PUSCH message in the first duplex configuration associated with the at least one first reference signal in the first common PO resource set. Of course, since the at least one first reference signal is associated with the first RO, the first PO associated with the at least one first reference signal can also be understood as the first RO-associated PO mentioned above.

[0280] Exemplarily, the configuration method of the first PO can include any one of the following:

[0281] Manner one:

[0282] Directly configure the PO resource of each TRP.

[0283] For example, the first network side device can configure the association relationship between the PO resource and the reference signal of the TRP (such as the reference signal group of the TRP or the index of the reference signal of the TRP), and accordingly, the terminal can directly determine the PO associated with the at least one first reference signal as the first PO. Of course, the first network side device can configure the association relationship between the PO resource and the TRP, and accordingly, the terminal can directly determine the PO associated with the first network side device as the first PO.

[0284] For another example, the first network side device can configure the association relationship between the RO and the PO, and accordingly, the terminal can directly determine the PO associated with the first RO as the first PO. For example, in NR, the association relationship between the PO and the RO is configured through MsgA-PUSCH-Resource.

[0285] Manner two:

[0286] Indirectly configure the first PO by configuring the first common PO resource set.

[0287] For example, after the first network side device configures the first common PO resource set associated with all reference signals (such as SSB) to the terminal, the terminal can determine the PO in the uplink resource unit or the flexible resource unit in the first duplex configuration associated with the at least one first reference signal in the first common PO resource set as the first PO associated with the at least one first reference signal.

[0288] It can be understood that the first PO in the downlink resource unit is an invalid PO, and the first network side device can dynamically adjust the activation (i.e., valid PO) and deactivation (i.e., invalid PO) of the first PO through different duplex configurations. Specifically, a specific duplex configuration or a dynamic duplex configuration can be used to configure the PO of different TRPs.

[0289] For another example, the first network side device can associate the third RO to the first common PO resource set, and the terminal determines the PO in the uplink resource unit or the flexible resource unit in the first duplex configuration associated with the at least one first reference signal in the first common PO resource set as the first PO. Wherein, the third RO can refer to the first RO, or the second RO, or one or more first ROs in the first common RO resource set, or any one or more second ROs in the second common RO resource set.

[0290] Particularly, if one PO in the first common PO resource set is associated with multiple ROs, if there is no valid RO in the multiple ROs, this PO is invalid; if there is a valid RO in the multiple ROs, the terminal can further determine whether this PO is the first PO, i.e., if this PO is a PO in the uplink resource unit or the flexible resource unit in the first duplex configuration associated with the at least one first reference signal, the terminal can determine this PO as the first PO.

[0291] The configuration scheme of the second PO is described below.

[0292] The first network side device directly or indirectly configures the second PO, which refers to a PO associated with a first signal set (including at least one second reference signal of the first network side device and at least one second reference signal of the second network side device) or a transmission opportunity for transmitting a PUSCH message in a duplex configuration (e.g., including a first duplex configuration associated with the at least one first reference signal and a duplex configuration associated with at least one second reference signal of the second network side device) associated with the first signal set in the second common PO resource set. Of course, since the at least one first reference signal is associated with a second RO, the second PO associated with the at least one first reference signal can also be understood as the PO associated with the second RO mentioned above.

[0293] Exemplarily, the configuration method of the second PO can include any of the following ways:

[0294] Way one:

[0295] Directly configure the PO resources of each TRP set.

[0296] For example, the first network side device can configure the association relationship between the PO resources and the reference signal set (e.g., the reference signal group of the TRP set or the index of the reference signal of the TRP set), and accordingly, the terminal can directly determine the PO associated with the first signal set to which the at least one first reference signal belongs as the second PO. Of course, the first network side device can configure the association relationship between the PO resources and the TRP set, and accordingly, the terminal can directly determine the PO associated with the set to which the first network side device belongs as the second PO.

[0297] For another example, the first network side device can configure the association relationship between the RO and the PO, and accordingly, the terminal can directly determine the PO associated with the second RO as the second PO. For example, in NR, the association relationship between the PO and the RO is configured through MsgA-PUSCH-Resource.

[0298] Way two:

[0299] By configuring the second common PO resource set, the second PO is indirectly configured.

[0300] For example, after the first network-side device configures the second common PO resource set to which all reference signals (e.g., SSB) are associated to the terminal, the terminal can determine the PO in the uplink resource unit or the flexible resource unit in the duplex configuration (e.g., including the first duplex configuration associated with the at least one first reference signal and the duplex configuration associated with the at least one second reference signal of the second network-side device) associated with the first signal set of the at least one second reference signal in the second common PO resource set as the second PO associated with the at least one second reference signal.

[0301] It can be understood that the second PO in the downlink resource unit is an invalid PO, and the first network-side device can dynamically adjust the activation (i.e., valid PO) and deactivation (i.e., invalid PO) of the second PO through different duplex configurations. Specifically, a specific duplex configuration or a dynamic duplex configuration can be used to configure the PO of different TRPs.

[0302] For another example, the first network-side device can associate the third RO resource to the second common PO resource set, and the terminal determines the PO resource in the uplink resource unit or the flexible resource unit in the duplex configuration associated with the first signal set in the second common PO resource set as the second PO. Wherein, the third RO can refer to one or more of the first RO, or the second RO, or the first common RO resource set, or any one or more of the second RO in the second common RO resource set.

[0303] Specifically, if one PO in the second common PO resource set is associated with multiple ROs, if there is no valid RO in the multiple ROs, the PO is invalid; if there is a valid RO in the multiple ROs, the terminal can further determine whether the PO is the second PO, i.e., if the PO is the PO in the uplink resource unit or the flexible resource unit in the first duplex configuration associated with the first signal set, the terminal can determine the PO as the first PO.

[0304] From the above, it can be known that the first network-side device can configure the first PO associated with the first RO, or the first common PO resource set associated with the third RO, or the second PO associated with the second RO, or the second common PO resource set associated with the third RO for the terminal. Wherein, the third RO can refer to one or more of the first RO, or the second RO, or the first common RO resource set, or any one or more of the second RO in the second common RO resource set.

[0305] Correspondingly, the first network-side device can configure the mapping relationship between the PO and the RO for the terminal for the first PO or the second PO. The first network-side device can configure the mapping relationship between the RO and the common PO resource set for the terminal for the first common PO resource set or the second common PO resource set. Specifically, the first network-side device can configure the mapping relationship for the terminal in any of the following manners:

[0306] Manner one:

[0307] First, determine the validity of the PO, and then establish the mapping relationship between the RO and the PO. For example, the first network-side device configures the first RO and the first PO association, and the second RO and the second PO association.

[0308] Manner two:

[0309] First, associate the third RO with the common PO resource set, and then determine the validity of the PO. For example, the first network-side device configures the third RO and the first common PO resource set / second common PO resource set for the terminal. Correspondingly, the terminal first determines the first PO / second PO in the first common PO resource set / second common PO resource set, then determines the validity of the first PO / second PO, and selects the valid first PO / second PO to send the PUSCH.

[0310] The rules of the mapping between the RO and the PO include:

[0311] Frequency domain: according to the increasing frequency domain resource index.

[0312] DMRS: according to the increasing DMRS resource index of the PO, wherein the index of the DMRS resource is first increased according to the DMRS port index, and then increased according to the DMRS sequence index.

[0313] Time domain: multiple PO resources in the same time slot are increased according to the time domain resource index, and PO resources in different time slots are increased according to the time slot index.

[0314] Exemplarily, the terminal can send a PRACH message on the first RO / second RO to initiate random access.

[0315] For four-step RACH (i.e. Type-1 RACH), the terminal selects one or more synchronization signals according to synchronization signal reception quality (RSRP, RSRQ, SNR, SINR, SIR, path loss, etc. indicators), and transmits a Msg1 signal on the first RO / second RO associated with the synchronization signal. For two-step RACH (i.e. Type-2 RACH), the terminal selects one or more synchronization signals according to synchronization signal reception quality (RSRP, RSRQ, SNR, SINR, SIR, path loss, etc. indicators), transmits a PRACH preamble signal on the first RO / second RO associated with the synchronization signal, and transmits a PUSCH signal to the first network side device on the first PO / second PO (PUSCH occasion) associated with the first RO / second RO.

[0316] In some embodiments, the at least one transmission opportunity includes the at least one first transmission opportunity and the at least one second transmission opportunity; the method 210 further includes:

[0317] The terminal determines a target transmission opportunity for transmitting a random access message from among the first transmission opportunity effective in the at least one first transmission opportunity and the second transmission opportunity effective in the at least one second transmission opportunity.

[0318] Exemplarily, the at least one first transmission opportunity includes at least one first RO, and the at least one second transmission opportunity includes at least one second RO; the terminal determines a target RO for transmitting a PRACH message from among the first RO effective in the at least one first RO and the second RO effective in the at least one second RO. Alternatively, the at least one first transmission opportunity includes at least one first PO, and the at least one second transmission opportunity includes at least one second PO; the terminal determines a target PO for transmitting a PUSCH message from among the first PO effective in the at least one first PO and the second PO effective in the at least one second PO.

[0319] In some embodiments, the terminal determines a target transmission opportunity for transmitting a random access message from among the first transmission opportunity effective in the at least one first transmission opportunity and the second transmission opportunity effective in the at least one second transmission opportunity, including:

[0320] The terminal determines the effective first transmission opportunity as the target transmission opportunity in at least one of the following cases:

[0321] The at least one first reference signal and the at least one second reference signal have no intersection;

[0322] The distance between the first network-side device and the second network-side device is greater than a preset distance.

[0323] The first network-side device and the second network-side device belong to a same device set.

[0324] In some embodiments, the terminal determines a target transmission opportunity for sending a random access message in a first transmission opportunity in which the terminal is effective and a second transmission opportunity in which the terminal is effective in the at least one first transmission opportunity and the at least one second transmission opportunity, including:

[0325] The terminal determines the effective second transmission opportunity as the target transmission opportunity in at least one of the following cases:

[0326] The at least one first reference signal and the at least one second reference signal have an intersection;

[0327] The distance between the first network-side device and the second network-side device is less than or equal to a preset distance.

[0328] The first network-side device and the second network-side device do not belong to a same device set.

[0329] Exemplarily, the terminal can determine the RO or the PO for sending the PRACH in any one of the following ways:

[0330] Way 1:

[0331] Whether a certain reference signal or a certain reference signal set associated to the two duplex configurations is the same or has an intersection. For example, when the same or the intersection exists, the second RO is used for sending the PRACH; otherwise, the first RO is used for sending the PRACH. For example, assuming that two TRPs send the same SSB in an SFN manner, the terminal sends the PRACH on the second RO in which both the TRPs are effective, which can meet the communication requirement.

[0332] Way 2:

[0333] Whether a certain TRP or a certain TRP set position associated to the two duplex configurations is close, such as the distance does not exceed a certain threshold. For example, when the distance is close, the second RO is used for sending the PRACH; otherwise, the first RO is used for sending the PRACH. Since the second RO is a RO in which both the TRPs are effective (i.e., both the TRPs are UL), the PRACH is sent by using the second RO, which can avoid the cross-link interference between the terminals, i.e., can avoid the cross interference caused by the PRACH of the terminal to the reception of the downlink signal by other terminals.

[0334] Way 3:

[0335] Whether the certain or the set of TRPs associated with the two duplex configurations belongs to the same set of TRPs. For example, when belonging to the same set, the PRACH is transmitted using the second RO resource; otherwise, the PRACH is transmitted using the first RO. When the two TRPs belong to the same set of TRPs, it can be indicated that the two TRPs serve the terminal in a coherent joint transmission (CJT) manner or belong to the same cooperative TRP cluster, and the PRACH of the terminal is received, at this time, the PRACH is transmitted using the second RO resource, which can meet the communication requirements.

[0336] In some embodiments, the condition under which the third transmission opportunity in the at least one transmission opportunity is valid comprises at least one of the following:

[0337] The third transmission opportunity is not earlier than a first time interval after a third reference signal, and the third reference signal is a first reference signal in the at least one first reference signal that is earlier than the third transmission opportunity;

[0338] The third transmission opportunity does not overlap with a fourth reference signal, and the fourth reference signal is a first reference signal in the at least one first reference signal that is not earlier than the third transmission opportunity.

[0339] Exemplarily, the third transmission opportunity can be the first transmission opportunity or the second transmission opportunity. For example, it can be any of the following: a first RO associated with the at least one first reference signal; a first RO in an uplink resource unit or a flexible resource unit in the first duplex configuration in a first common RO resource set associated with the first signal set; a second RO associated with the first signal set; a second RO in an uplink resource unit or a flexible resource unit in the duplex configuration associated with the first signal set in a second common RO resource set associated with the first signal set; a first PO associated with the at least one first reference signal; a first PO in an uplink resource unit or a flexible resource unit in the first duplex configuration in a first common PO resource set associated with the first signal set; a second PO associated with the first signal set; a second PO in an uplink resource unit or a flexible resource unit in the duplex configuration associated with the first signal set in a second common PO resource set associated with the first signal set. Wherein, the first signal set comprises the at least one first reference signal and at least one second reference signal of the second network side device.

[0340] Exemplarily, the first time interval is denoted as N gap . N gap Defined by a protocol or indicated by a network side, for example, N gap Determined according to the SCS of the preamble resource, or N gapdetermined according to the SCS of the activated uplink frequency domain resource (e.g., UL BWP).

[0341] Exemplarily, the third transmission opportunity is a first RO / second RO, the first RO / second RO is not earlier than a third reference signal by N gap , the third reference signal is a first reference signal in the at least one first reference signal that is earlier than the first RO / second RO, or the first RO / second RO does not overlap with a fourth reference signal, the fourth reference signal is a first reference signal in the at least one first reference signal that is not earlier than the first RO / second RO; wherein N gap is predefined by a protocol or indicated by a network side, for example, N gap determined according to the SCS of the preamble resource.

[0342] It can be understood that when the first RO / second RO is located in a flexible slot (the time domain format is X), the first RO / second RO is the same as the time domain resource of the third reference signal, but is different from the frequency domain resource of the third reference signal, which does not belong to resource overlap.

[0343] In some embodiments, in the case that the third transmission opportunity is a physical uplink shared channel (PUSCH) opportunity, the condition under which the third transmission opportunity is valid further includes:

[0344] The third transmission opportunity and the valid physical random access channel (PRACH) opportunity associated with the at least one first reference signal do not overlap.

[0345] Exemplarily, the third transmission opportunity is a first PO / second PO, the first PO / second PO is not earlier than a third reference signal by N gap , the third reference signal is a first reference signal in the at least one first reference signal that is earlier than the first PO / second PO, or the first PO / second PO does not overlap with a fourth reference signal, the fourth reference signal is a first reference signal in the at least one first reference signal that is not earlier than the first PO / second PO; wherein N gap is predefined by a protocol or indicated by a network side, for example, N gap determined according to the SCS of the activated uplink frequency domain resource (e.g., UL BWP).

[0346] It can be understood that when the first PO / second PO is located in a flexible slot (the time domain format is X), the first PO / second PO is the same as the time domain resource of the third reference signal, but is different from the frequency domain resource of the third reference signal, which does not belong to resource overlap.

[0347] In some embodiments, the third transmission opportunity is not earlier than a first time interval after a third reference signal, including that the third transmission opportunity is not earlier than the first time interval after the third reference signal within a time unit in which the third transmission opportunity is located, or the third transmission opportunity is not earlier than the first time interval after the third reference signal within an uplink resource unit or a flexible resource unit under a duplex configuration of the terminal; or

[0348] The third transmission opportunity does not overlap with a fourth reference signal, including that the third transmission opportunity does not overlap with the fourth reference signal within a time unit in which the third transmission opportunity is located, or the third transmission opportunity does not overlap with the fourth reference signal within an uplink resource unit under a duplex configuration of the terminal.

[0349] In some embodiments, the at least one transmission opportunity includes at least one of:

[0350] A physical random access channel opportunity (PRACH occasion, RO);

[0351] A MsgA physical uplink shared channel opportunity (PUSCH Occasion, PO);

[0352] A Configured-grant (CG) based PUSCH opportunity.

[0353] Exemplarily, the Configured-grant (CG) based PUSCH opportunity can be a Configured-grant (CG) based PO in an RRC idle / inactive state.

[0354] The following describes a scheme for judging the validity of the RO.

[0355] Exemplarily, the protocol defines a RO validity judgment rule based on the at least one first reference signal. The conditions for the RO to be valid for the at least one first reference signal (associated TRP) include:

[0356] When the network does not indicate a common duplex configuration, the RO is not earlier than N gap time intervals after a third reference signal within a PRACH slot in which the RO is located, the third reference signal being a first reference signal in the at least one first reference signal that is earlier than the RO, or the RO does not overlap with a fourth reference signal within the PRACH slot in which the RO is located, the fourth reference signal being a first reference signal in the at least one first reference signal that is not earlier than the RO.

[0357] Exemplarily, if the network configuration parameter channelAccessMode = "semiStatic", the RO is valid if it does not overlap with a set of consecutive symbol set occupied by other terminals, before the start of the next channel occupancy time in which the terminal does not transmit signals.

[0358] Exemplarily, the common duplex configuration is, for example, tdd-UL-DL-ConfigurationCommon in TDD configuration or SBFD configuration.

[0359] Exemplarily, N gap Predefined by protocol or indicated by network side, for example, N gap Determined according to the SCS of the preamble resource.

[0360] Exemplarily, the at least one first reference signal is, for example, SSB / SIB / MIB / Paging, etc.; the overlap can include partial symbol overlap, and also include full symbol overlap.

[0361] When the network indicates the common duplex configuration, the RO is not earlier than the N gap th reference signal in the uplink resource unit of the common duplex configuration of the terminal, the third reference signal being the first reference signal in the at least one first reference signal that is earlier than the RO; or the RO does not overlap with the fourth reference signal in the uplink resource unit of the common duplex configuration of the terminal, the fourth reference signal being the first reference signal in the at least one first reference signal that is not earlier than the RO.

[0362] Exemplarily, if the network configuration parameter channelAccessMode = "semiStatic", the RO is valid if it does not overlap with a set of consecutive symbol set occupied by other terminals, before the start of the next channel occupancy time in which the terminal does not transmit signals.

[0363] Exemplarily, the common duplex configuration of the terminal can be a common duplex configuration at cell level or a common duplex configuration at TRP level. That is, the network side device can configure the terminal with a common duplex configuration at cell level or a common duplex configuration at TRP level. Regardless of the level of the common duplex configuration, the validity of the RO can be determined based on the at least one first reference signal.

[0364] Exemplarily, the common duplex configuration is, for example, tdd-UL-DL-ConfigurationCommon in TDD configuration or SBFD configuration.

[0365] Exemplarily, the uplink resource unit comprises a UL symbol, a UL slot, a UL subband on a flexible (X) symbol, or a UL subband on a flexible (X) slot.

[0366] Exemplarily, N gap Predefined by a protocol or indicated by a network side, for example, N gap Determined according to the SCS of the preamble resource.

[0367] Exemplarily, the at least one first reference signal is, for example, SSB / SIB / MIB / Paging, etc.; the overlap can include partial symbol overlap, and also full symbol overlap.

[0368] For example, consider the Common TDD configuration and the dedicated TDD format of TRP1 and TRP2, and the SSB time domain position is shown in the following table.

[0369] Table 3

[0370] As shown in Table 3, whether the RO and the SSB of TRP1 and the SSB of TRP2 overlap is compared, that is, because there is an SSB overlapping any RO in {RO#1, RO#2, RO#3, RO#4} in the SSB of TRP1 and the SSB of TRP2, all ROs are invalid. However, according to the RO validity judgment rule provided in the embodiment, the SSB {SSB#1, SSB#2, SSB#3} of TRP1 is associated with TRP1, and the valid RO is RO {#3, #4}; the SSB {SSB#1, SSB#4, SSB#5} of TRP2 is associated with TRP2, and the valid RO is RO {#1, #2}.

[0371] The following describes a scheme for judging the validity of the MsgA PO.

[0372] Exemplarily, the protocol defines a MsgA PO validity judgment rule based on the at least one first reference signal. The conditions under which the MsgA PO is valid for the at least one first reference signal (associated TRP) include:

[0374] When the network does not indicate the common duplex configuration, the MsgA PO is not earlier than N gap, the third reference signal is a first reference signal among the at least one first reference signal that is earlier than the MsgA PO; or the MsgA PO does not overlap with a fourth reference signal within the uplink resource unit under the common duplex configuration of the terminal, the fourth reference signal being a first reference signal among the at least one first reference signal that is not earlier than the MsgA PO.

[0375] Exemplarily, if the network configuration parameter channelAccessMode = "semiStatic", the MsgA PO is valid if it does not overlap with a set of continuous symbol set occupied by other terminals before the start of the next channel occupancy time in which the terminal does not transmit signals.

[0379] When the network indicates the common duplex configuration, the MsgA PO is not earlier than the third reference signal within the uplink resource unit under the common duplex configuration of the terminal, N gap , the third reference signal is a first reference signal among the at least one first reference signal that is earlier than the MsgA PO; or the MsgA PO does not overlap with a fourth reference signal within the uplink resource unit under the common duplex configuration of the terminal, the fourth reference signal being a first reference signal among the at least one first reference signal that is not earlier than the MsgA PO.

[0380] Exemplarily, if the network configuration parameter channelAccessMode = "semiStatic", the MsgA PO is valid if it does not overlap with a set of continuous symbol set occupied by other terminals before the start of the next channel occupancy time in which the terminal does not transmit signals.

[0381] Exemplarily, the common duplex configuration of the terminal can be a common duplex configuration at a cell level or a common duplex configuration at a TRP level. In other words, the network side device can configure the terminal with a common duplex configuration at a cell level or a common duplex configuration at a TRP level. Regardless of the level of the common duplex configuration, the validity of the MsgA PO can be determined based on the at least one first reference signal.

[0382] Exemplarily, the common duplex configuration is, for example, tdd-UL-DL-ConfigurationCommon in a TDD configuration or an SBFD configuration.

[0383] Exemplarily, the uplink resource unit includes an UL symbol, an UL slot, an UL subband on a flexible (X) symbol, or an UL subband on a flexible (X) slot.

[0384] Exemplarily, N gap Predefined by a protocol or indicated by the network side, for example, N gap Determined according to the SCS of the activated uplink frequency domain resource (for example, an UL BWP).

[0385] Exemplarily, the at least one first reference signal is, for example, an SSB / SIB / MIB / Paging, etc. The overlap can include a partial symbol overlap or a full symbol overlap.

[0386] The following describes a scheme for judging the validity of a CG based PO (a typical scenario is, for example, Small Data Transmission (SDT)).

[0387] Exemplarily, a protocol defines a CG based PO validity judgment rule based on the at least one first reference signal. The conditions under which the CG based PO is valid for the at least one first reference signal (associated TRP) include:

[0388] The CG based PO does not overlap, in terms of time resources and frequency domain resources, with an effective RO associated with the at least one first reference signal, and the effective RO includes ROs of 4-step RACH and 2-step RACH.

[0389] When the network does not indicate the common duplex configuration, the CG based PO is not earlier than N gap, the third reference signal is a first reference signal in the at least one first reference signal earlier than the CG based PO; or the CG based PO does not overlap with a fourth reference signal in an uplink resource unit under the common duplex configuration of the terminal, the fourth reference signal being a first reference signal in the at least one first reference signal not earlier than the CG based PO.

[0390] Exemplarily, the common duplex configuration is, for example, tdd-UL-DL-ConfigurationCommon in a TDD configuration or an SBFD configuration.

[0391] Exemplarily, N gap Predefined by a protocol or indicated by a network side.

[0392] Exemplarily, the at least one first reference signal is, for example, SSB / SIB / MIB / Paging, etc.; the overlap can include partial symbol overlap, and also full symbol overlap.

[0393] When the network indicates the common duplex configuration, the CG based PO is not earlier than the third reference signal after N gap , the third reference signal is a first reference signal in the at least one first reference signal earlier than the CG based PO; or the CG based PO does not overlap with a fourth reference signal in an uplink resource unit under the common duplex configuration of the terminal, the fourth reference signal being a first reference signal in the at least one first reference signal not earlier than the CG based PO.

[0394] Exemplarily, the common duplex configuration of the terminal can be a common duplex configuration at a cell level or a common duplex configuration at a TRP level. That is, the network side device can configure the terminal with a common duplex configuration at a cell level or a common duplex configuration at a TRP level. Regardless of the level of the common duplex configuration, the validity of the CG based PO can be determined based on the at least one first reference signal.

[0395] Exemplarily, the common duplex configuration is, for example, tdd-UL-DL-ConfigurationCommon in a TDD configuration or an SBFD configuration.

[0396] Exemplarily, the uplink resource unit includes an UL symbol, an UL slot, an UL subband on a flexible (X) symbol, or an UL subband on a flexible (X) slot.

[0397] Exemplarily, N gap Predefined by a protocol or indicated by a network side.

[0398] Exemplarily, the at least one first reference signal is, for example, SSB / SIB / MIB / Paging, etc.; and the overlap can include partial symbol overlap, and also include full symbol overlap.

[0399] In some embodiments, the method 210 further includes:

[0400] The terminal receives first scheduling information from the first network-side device;

[0401] The first scheduling information is used for scheduling a first time unit, and the condition that the first time unit is not counted into the available time unit of the first uplink channel includes:

[0403] In some embodiments, the method 210 further includes:

[0404] The terminal receives first indication information from the first network-side device;

[0405] The first indication information is used for indicating a second time unit, and a consecutive time unit starting from the second time unit as the available time unit of the first uplink channel includes at least one of the following:

[0406] A first symbol in the second time unit is an uplink time unit or a flexible time unit, and does not overlap with the at least one first reference signal;

[0407] A consecutive uplink symbol or flexible symbol starting from the first symbol in the second time unit and having a quantity greater than or equal to a preset value does not overlap with the at least one first reference signal.

[0408] In some embodiments, the first uplink channel includes at least one of the following:

[0409] Message 3 physical uplink shared channel Msg3 PUSCH;

[0411] Repeated transmission physical uplink shared channel PUSCH;

[0412] Repeated transmission physical uplink control channel PUCCH.

[0413] The following describes a scheme in which the terminal determines available slots of Msg3 PO based on the at least one first reference signal and rules for not performing Msg3 PUSCH transmission. The at least one first reference signal can also be replaced by a duplex configuration or a TRP / TRP group associated with the at least one first reference signal.

[0414] When Msg3 PUSCH repetition transmission is performed: the terminal performs Msg3 PUSCH repetition transmission using N×K available slots, where K is the number of repetition transmissions, and N is the number of slots occupied by TB processing (default is 1), and the judgment rule of the available slots includes:

[0415] If the repetition transmission of Msg3 PUSCH is RAR scheduled (i.e., PUSCH repetition when Msg3 initial transmission is performed) PUSCH slot and the at least one first reference signal (e.g., SSB, configured by the ssb-PositionsInBurst parameter) or the downlink resource unit in the common duplex configuration (including tdd-UL-DL-ConfigurationCommon) associated with the at least one first reference signal has at least one symbol overlap, the PUSCH slot does not belong to the available slots of the repetition transmission of Msg3 PUSCH, the PUSCH slot does not transmit PUSCH signals, and is not counted in the N×K available slots.

[0416] Exemplarily, the common duplex configuration associated with the at least one first reference signal can be a cell-level duplex configuration or a TRP-level duplex configuration.

[0417] If the repetition transmission of Msg3 PUSCH is scheduled by a DCI format 0_0 scrambled by TC-RNTI (i.e., PUSCH repetition when Msg3 retransmission is performed) PUSCH slot and the at least one first reference signal (e.g., SSB, configured by the ssb-PositionsInBurst parameter) or the downlink resource unit in the common duplex configuration associated with the at least one first reference signal has at least one symbol overlap, the PUSCH slot does not belong to the available slots of the repetition transmission of Msg3 PUSCH, the PUSCH slot does not transmit PUSCH signals, and is not counted in the N×K available slots.

[0418] Exemplarily, the common duplex configuration associated with the at least one first reference signal can be a cell-level duplex configuration or a TRP-level duplex configuration.

[0419] The following describes a scheme for the terminal to determine available slots of TBoMS PUSCH (i.e., considering PUSCH across multiple slots) based on the at least one first reference signal and rules for not performing TBoMS PUSCH transmission. The at least one first reference signal can also be replaced by a duplex configuration or a TRP / TRP group associated with the at least one first reference signal. The terminal performs TBoMS PUSCH transmission using N×K available slots, and the judgment rule for the N×K available slots of the TBoMS PUSCH includes:

[0420] If the TBoMS PUSCH is DCI format 0_1 or 0_2 scheduling, if the scheduled slot has at least one symbol overlapping with a downlink resource element in the at least one first reference signal (e.g., SSB, configured by the ssb-PositionsInBurst parameter) or a common duplex configuration (including tdd-UL-DL-ConfigurationCommon) associated with the at least one first reference signal or a specific duplex configuration (including tdd-UL-DL-ConfigurationDedicated) associated with the at least one first reference signal, the scheduled slot does not belong to the available slot, the scheduled slot does not transmit the TBoMS PUSCH, and is not counted in the N×K available slots of the TBoMS PUSCH.

[0421] Exemplarily, the common duplex configuration or the specific duplex configuration associated with the at least one first reference signal can be a cell-level duplex configuration or a TRP-level duplex configuration.

[0422] The following describes a scheme for the terminal to determine available slots of PUSCH repetition transmission based on the at least one first reference signal and rules for not performing PUSCH repetition transmission. The at least one first reference signal can also be replaced by a duplex configuration or a TRP / TRP group associated with the at least one first reference signal.

[0423] When the number of PUSCH repetition transmission is greater than 1 (K>1), the judgment rule for the available slots of the PUSCH repetition transmission can include:

[0424] When AvailableSlotCounting is supported, the terminal performs PUSCH repetition transmission using N×K available slots, and the judgment rule for the available slots of the PUSCH repetition transmission can include:

[0425] If the PUSCH repetition transmission is scheduled by DCI format 0_1 or 0_2, if the scheduled slot has at least one symbol overlap with the downlink resource elements in the at least one first reference signal (e.g. SSB, configured by ssb-PositionsInBurst parameter), or the downlink resource elements in the common duplex configuration (including tdd-UL-DL-ConfigurationCommon) associated with the at least one first reference signal, or the downlink resource elements in the specific duplex configuration (including tdd-UL-DL-ConfigurationDedicated) associated with the at least one first reference signal, the scheduled slot does not belong to the available slots, the scheduled slot does not transmit the PUSCH repetition transmission, and is not counted in the N×K available slots for the PUSCH repetition transmission.

[0426] Exemplarily, the common duplex configuration or the specific duplex configuration associated with the at least one first reference signal can be a cell-level duplex configuration, or a TRP-level duplex configuration.

[0427] When the available slot counting (AvailableSlotCounting) is not supported, the terminal uses the N×K available slots for the PUSCH repetition transmission, and the judgment rule of the available slots for the PUSCH repetition transmission can include:

[0428] If the scheduled slot has at least one symbol overlap with the downlink resource elements in the at least one first reference signal (e.g. SSB, configured by ssb-PositionsInBurst parameter), or the downlink resource elements in the common duplex configuration (including tdd-UL-DL-ConfigurationCommon) associated with the at least one first reference signal, or the downlink resource elements in the specific duplex configuration (including tdd-UL-DL-ConfigurationDedicated) associated with the at least one first reference signal, the terminal does not perform the PUSCH repetition transmission on the scheduled slot. Otherwise, the terminal can perform the PUSCH repetition transmission on the scheduled slot.

[0429] Exemplarily, the common duplex configuration or the specific duplex configuration associated with the at least one first reference signal can be a cell-level duplex configuration, or a TRP-level duplex configuration.

[0430] Exemplarily, the slot in which the terminal does not perform the PUSCH repetition transmission due to the above rule is also counted in the N×K slots.

[0431] The following describes a scheme for the terminal to determine available slots for PUCCH repetition transmission based on the at least one first reference signal and rules for not performing PUCCH repetition transmission. The at least one first reference signal can also be replaced by the duplex configuration or TRP / TRP group associated with the at least one first reference signal. When considering PUCCH repetition transmission, the terminal determines available slots for PUCCH repetition transmission from the time slot indicated by the network, and the determination rules of the available slots include:

[0432] the first symbol in the starting time slot is an uplink time unit or a flexible time unit and does not overlap with the at least one first reference signal;

[0433] the first symbol in the starting time slot starts and the number of consecutive uplink symbols or flexible symbols is greater than or equal to a preset value. The preset threshold can be a symbol number indicated by the nrofsymbols parameter agreed by the protocol or configured by the network.

[0434] It can be understood that the first symbol, the consecutive uplink symbol or the flexible symbol can be measured by "symbol" or other time units other than "slot".

[0435] In a full-duplex (FD) cell-free architecture, when different TRPs have different duplex configurations, the PRACH signal of the uplink time slot of a certain TRP can interfere with the downlink reception of certain TRPs when the same time slot is a downlink time slot.

[0436] For example, there is cross-link interference (CLI) between different TRPs, that is, a TRP in a downlink transmission time slot can cause cross-link interference between TRPs for a TRP in an uplink transmission time slot, and a UE in an uplink transmission time slot can cause cross-link interference between UEs for a UE in a downlink transmission time slot. This requires the CPU in the cell-free network to control each TRP to perform CLI measurement and reduce CLI by optimizing UE-TRP connection and network-side beamforming.

[0437] For the problem of interference between TRPs, on the one hand, the TRP can eliminate the interference between TRPs through baseband signal processing.

[0438] For example, the interference from TRP1 to TRP2, since TRP1 determines the content of TRP1 downlink signal, TRP2 can receive the TRP1 downlink signal and estimate the interference channel between TRP1 and TRP2 through the reference signal such as DMRS carried therein, based on which, TRP1 can eliminate the TRP1 downlink signal interference from the TRP2 receiving signal through baseband signal processing based on the estimated interference.

[0439] On the other hand, the interference can be reduced by adjusting the uplink transmission power.

[0440] For example, as shown in FIG. 8, the PRACH transmitted by TRP2 based on SSB in the third time slot will cause cross interference to the downlink signals of TRP1 and TRP3 in the third time slot. The PRACH transmitted by TRP1 based on SSB in the fifth time slot will not cause interference to any downlink signal. Therefore, the PRACH transmission power configuration in the third time slot and the fifth time slot can be different, for example, the third time slot can be configured with lower power to reduce the interference to the downlink signals under the coverage of adjacent TRPs (i.e. TRP1 and TRP3). This requires more flexible configuration of uplink power control parameters for random access for different ROs or POs.

[0441] The following describes a scheme for uplink transmission power control of a terminal.

[0442] In some embodiments, the method 210 further includes:

[0443] The terminal determines the uplink transmission power of the first uplink signal transmitted on the first uplink resource according to the characteristics of the first uplink resource.

[0444] It should be noted that the terminal can be configured with multiple random access resources in different time slot positions, and the interference environment in different time slot positions is different under the assumption of full-duplex cell free network architecture (for example, the cross interference between the terminals is large in the first time slot, and the cross interference between the terminals is small in the second time slot). Cross interference refers to the interference caused by the uplink signal transmission of the terminal in the same time and frequency domain resource to the downlink signal reception of the terminal, also known as cross-link interference or cross-link interference. If the terminal performs power boosting according to the transmission power of the last transmission when transmitting multiple random access messages, or does not consider the time slot position of the selected RO resource when transmitting multiple random access messages, it may introduce large cross interference or the transmission power cannot meet the needs of random access message transmission, causing transmission performance degradation.

[0445] In the embodiment, the terminal determines the uplink transmission power of the first uplink signal transmitted on the first uplink resource according to the characteristic of the first uplink resource, which can reduce cross interference and further improve the success rate of random access and transmission performance.

[0446] For example, the terminal can determine the uplink transmission power according to a characteristic change of the first uplink resource. The characteristic change indicates whether the characteristic of the first uplink resource changes relative to the characteristic of a second uplink resource used to transmit the first uplink signal before the first uplink resource, that is, includes both a characteristic change and no characteristic change.

[0447] For example, taking the first uplink resource as the random access resource for the Nth random access transmission and the second uplink resource as the random access resource for the (N-1)th random access transmission as an example, when the terminal performs the Nth random access message transmission on the RO of the same type as the last random access message transmission, the characteristic of the first uplink resource is the same as that of the second uplink resource, that is, no characteristic change occurs; when the terminal performs the Nth random access message transmission on the RO of a different type from the last random access message transmission, the characteristic of the first uplink resource is different from that of the second uplink resource, that is, a characteristic change occurs.

[0448] In other words, the characteristic change of the Nth random access transmission includes the following two cases:

[0449] Case 1:

[0450] The terminal transmits a first random access message on a first type of random access resource at the (N-1)th random access message transmission; the terminal also transmits a first random access message on the first type of random access resource at the Nth random access message transmission; that is, the terminal performs the Nth random access message transmission on the RO of the same type as the last random access message transmission.

[0451] Case 2:

[0452] The terminal transmits a first random access message on a first type of random access resource at the (N-1)th random access message transmission; the terminal transmits a first random access message on a second type of random access resource at the Nth random access message transmission; that is, the terminal performs the Nth random access message transmission on the RO of a different type from the last random access message transmission.

[0453] In some embodiments, the terminal determines the uplink transmission power of the first uplink signal transmitted on the first uplink resource according to the characteristic of the first uplink resource, including:

[0454] The terminal determines at least one power parameter according to the characteristic of the first uplink resource.

[0455] The terminal determines the uplink transmission power according to the at least one power parameter.

[0456] In some embodiments, the at least one power parameter comprises at least one of the following:

[0457] a power boosting parameter associated with the characteristic of the first uplink resource;

[0458] a power offset value associated with the characteristic of the first uplink resource.

[0459] Exemplarily, the power boosting parameter comprises at least one of the following: a power boosting step, a power boosting counter, a power boosting maximum number.

[0460] In some embodiments, in the case that the characteristic of the first uplink resource is different from the characteristic of a second uplink resource used for transmitting the first uplink signal before the first uplink resource, the at least one power parameter comprises a characteristic change offset value in addition to the power offset value associated with the characteristic of the first uplink resource.

[0461] In some embodiments, the terminal determines the uplink transmission power according to the at least one power parameter, comprising:

[0462] The terminal acquires a first power of a second uplink resource used for transmitting the first uplink signal before the first uplink resource; and the terminal determines the uplink transmission power according to the first power and the at least one power parameter.

[0463] Exemplarily, taking the first uplink resource as a random access resource for the Nth random access transmission and the second uplink resource as a random access resource for the (N-1)th random access transmission as an example, when the terminal determines the uplink transmission power for the Nth random access transmission, the terminal can determine the uplink transmission power P(n) for the Nth random access transmission according to the first uplink transmission power P(n-1) for the (N-1)th random access transmission, a first power parameter associated with the characteristic of the random access resource for the Nth random access transmission, a second power parameter associated with the characteristic of the random access resource for the Nth random access transmission, or a third power parameter associated with the characteristic of the random access resource for the Nth random access transmission.

[0464] The first power parameter comprises:

[0465] a power boosting parameter delta_k corresponding to the kth type of random access resource or the kth type of time slot position where the random access resource is located (defaulted as 0).

[0466] a mapping relationship between the random access resource type or the time slot position where the random access resource is located and the power boosting parameter; wherein the power boosting parameter comprises at least one of the following: a power boosting step, a power boosting counter, a maximum number of power boosting times;

[0467] the second power parameter comprises:

[0468] a power offset value offset_k (defaulted as 0) corresponding to the kth type of random access resource or the kth type of time slot position where the random access resource is located, that is, when the kth type of random access resource is used for random access message transmission, the uplink transmission power needs to be adjusted according to the power offset value; the power offset value is configured by the network and corresponds to the RO resource type or the time slot position where the RO resource is located;

[0469] a mapping relationship between the random access resource type or the time slot position where the random access resource is located and the power offset value;

[0470] the third power parameter comprises:

[0471] a power offset value delta_change (defaulted as 0) corresponding to the changed RO resource type or the changed time slot position where the random access is located;

[0472] when the kth type of random access resource or the kth type of time slot position where the random access resource is located is used for the Nth time of random access transmission, if the feature change of the Nth time of random access transmission is the above case 1, the corresponding uplink transmission power is P(n) = P(n-1) + delta_k-offset_k, or P(n) = P(n-1) + delta_k+offset_k; if the feature change of the Nth time of random access transmission is the above case 2, the corresponding uplink transmission power is P(n) = P(n-1) + delta_change+delta_k-offset_k, or P(n) = P(n-1) + delta_change+delta_k+offset_k.

[0473] The following will be exemplarily explained in combination with Table 4.

[0482] If the characteristic change of the Nth random access transmission is the above case 1, the corresponding uplink transmission power is P(n) = min(Pmax_k, Ptarget_k + PL_k + delta_k - offset_k), or P(n) = min(Pmax_k, Ptarget_k + PL_k + delta_k + offset_k); if the characteristic change of the Nth random access transmission is the above case 2, the corresponding uplink transmission power is P(n) = min(Pmax_k, Ptarget_k + PL_k + delta_change + delta_k - offset_k), or P(n) = min(Pmax_k, Ptarget_k + PL_k + delta_change + delta_k + offset_k).
