[0053] The wireless communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0054] Figure 2 This is a schematic flowchart of a wireless communication method 200 according to an embodiment of this application, such as... Figure 2 As shown, the wireless communication method 200 may include at least some of the following:

[0055] S210, the terminal receives first information from the target cell; wherein, the first information is information periodically sent by the target cell, or, the first information is information not sent based on a request, and the target cell is a cell that non-periodically sends SIBs;

[0057] S230, the terminal performs a first target operation; wherein the first target operation includes one of a first operation, a second operation, and a third operation.

[0058] It should be understood that Figure 2The steps or operations of the wireless communication method 200 are illustrated, but these steps or operations are merely examples, and other operations may be performed in this application. Figure 2 Variations of various operations within it.

[0059] In this embodiment of the application, the target cell can be a cell that transmits SIBs (such as SIB1) non-periodically. For example, the target cell can be a non-energy-saving cell (NES cell).

[0060] In the embodiments of this application, the terminal sends a target uplink transmission, thereby enabling access to the target cell; or, the terminal sends a target uplink transmission, thereby enabling it to request second information and / or SIB (such as SIB1) as needed, and determine whether it can access the target cell based on the second information and / or SIB (such as SIB1); or, the terminal sends a target uplink transmission (equivalent to Msg1 or MsgA) and then receives Msg2 or MsgB in the random access process, thereby enabling it to directly perform the random access procedure, saving the overhead of sending Msg1 or MsgA, simplifying the process of the terminal accessing the target cell, and improving the efficiency of the terminal accessing the target cell.

[0061] In this embodiment, the first target operation includes one of a first operation, a second operation, and a third operation. This can be understood as follows: the terminal is aware in advance that it may execute the first operation, the second operation, or the third operation; then, the terminal executes one of the first, second, or third operations based on the actual situation. Alternatively, in this embodiment, the first target operation including one of the first, second, and third operations can also be understood as: the terminal executes the first operation based on the actual situation, or the terminal executes the second operation based on the actual situation, or the terminal executes the third operation based on the actual situation.

[0062] For example, if the terminal only wants to camp on the target cell, in this case, after sending the target uplink transmission, the terminal receives the second information and SIB (such as SIB1) to camp on the target cell.

[0063] For example, if a terminal has a service to be transmitted, in this case, after the terminal sends the target uplink transmission, it receives SIB (such as SIB1), and after receiving SIB (such as SIB1), it receives Msg2. Then, it sends Msg3 for random access and receives Msg4 to access the target cell.

[0064] The first information described in the embodiments of this application may include part or all of the contents of a Synchronization Signal Block (SSB). Optionally, if the first information includes part of the contents of an SSB, the first information may also be referred to as a first-level SSB, a first part of an SSB, or a first partial SSB, or other similar names. The first information may also include other content besides part of the contents of an SSB, and this application is not limited in this regard. Optionally, if the first information includes all of the contents of an SSB, the first information may also be referred to as an SSB, or other similar names. The first information may also include other content besides all of the contents of an SSB, and this application is not limited in this regard.

[0065] The second information described in this application embodiment can be information sent aperiodically by the target cell, or it can be information sent based on a request. For example, the target cell sends the second information based on a target uplink transmission, or a target uplink transmission request triggers the target cell to send the second information.

[0066] The second information described in the embodiments of this application may include a portion of the content of an SSB. The second information may also be referred to as a second-level SSB, a second part of an SSB, or a second part of an SSB, or other similar names. The second information may also include other content besides a portion of the content of an SSB, and this application does not limit this.

[0067] The first information described in the embodiments of this application may also be referred to as a reference signal and / or system information block, and the second information described in the embodiments of this application may also be referred to as a reference signal and / or system information block. This application does not limit this.

[0068] For example, the first information or the second information can be as follows: Figure 3 As shown, in Figure 3 In A and B, the first or second information can specifically include PSS+SSS+PBCH. The first or second information can occupy 4 symbols in the time domain and 20 physical resource blocks (PRBs) in the frequency domain.

[0069] For example, the first information or the second information can be as follows: Figure 4 As shown, in Figure 4 In A and B, the first or second information can specifically include PSS+SSS. The first or second information can occupy 2 symbols in the time domain and 127 subcarriers in the frequency domain. For example... Figure 4 As shown in B, PSS+SSS occupies no more than 12 PRBs of resources in the frequency domain.

[0070] For example, the first information or the second information can be as follows: Figure 5 As shown, in Figure 5 In A, B, C, and D, the first or second information may specifically include PSS+SSS+PBCH. The first or second information may occupy at least one symbol in the time domain and at least one subcarrier (e.g., 127 subcarriers) in the frequency domain.

[0071] For example, the first information or the second information can be as follows: Figure 6 As shown, in Figure 6 In A, B, C, and D, the first or second information can specifically include PSS+SSS+PBCH. The first or second information can occupy at least one symbol in the time domain and at least one PRB (e.g., 12 PRBs) in the frequency domain. Figure 6 As shown, PSS+SSS occupies 127 subcarriers in the frequency domain, and PBCH occupies 12 PRBs in the frequency domain.

[0072] For example, the first information or the second information can be as follows: Figure 7 As shown, in Figure 7 In A and B, the first or second information may specifically include PBCH, and the first or second information may occupy at least one symbol in the time domain and Q PRBs in the frequency domain.

[0073] For example, the first information could be a portion of PSS+SSS plus PBCH, such as Figure 5 As shown in A, B, and C; the second information is another part of the PBCH, as shown in... Figure 7 As shown in B in the diagram.

[0074] It should be noted that the above Figures 3 to 7 The numbers in the table are typical values ​​and may not be the values ​​in the examples. You can use letters to represent any value greater than or equal to 1. The values ​​mentioned above can also be zero.

[0075] It should be noted that the above Figures 3 to 7 The units of frequency domain resources can be resource blocks (RBs), PRBs, common resource blocks (CRBs), or subcarriers, etc.

[0076] The SIBs described in the embodiments of this application include at least SIB1, but may also include other SIBs, and this application does not limit them.

[0077] The SSB described in this application embodiment can also be called any signal set or signal module that includes at least one of the following: synchronization signal, broadcast signal, physical broadcast channel (PBCH), other system message downlink broadcast channel and its control channel, or control resource set, or control channel search space.

[0078] The messages (Msg) in the random access process described in this application embodiment may include messages in a four-step random access process and messages in a two-step random access process; wherein, the messages in the four-step random access process include at least one of the following: Msg1, Msg2, Msg3, Msg4; wherein, the messages in the two-step random access process include at least one of the following: MsgA, MsgB.

[0079] In some embodiments, the target uplink transmission function includes, but is not limited to, one of the following:

[0080] Request to remain in the target cell;

[0081] Request the target cell to send the second information;

[0082] Request the target cell to send an SIB;

[0083] The target cell is requested to send the second information and SIB;

[0084] Request access to the target cell;

[0085] The system requests the target cell to send second information and requests access to the target cell.

[0086] The system requests the target cell to send an SIB and requests access to the target cell.

[0087] The system requests the target cell to send the second information and SIB, and requests access to the target cell.

[0088] In this embodiment, the network-side device can perform corresponding operations based on the target uplink transmission function.

[0089] For example, if the function of the target uplink transmission is to request the target cell to send second information, and if the second information contains the information necessary for the terminal to camp on the target cell, after the terminal performs the target uplink transmission, it receives the second information. Based on the second information, the terminal can first determine whether the target cell allows the terminal to camp.

[0090] For example, if the function of the target uplink transmission is to request the target cell to send an SIB (such as SIB1), after the terminal performs the target uplink transmission, the terminal listens for Type 0PDCCH (receives SIB1), and if there is a service to be transmitted, the terminal initiates the random access procedure.

[0091] For example, if the target uplink transmission function is to request the target cell to send an SIB (such as SIB1) and to request access to the target cell (i.e., to initiate connection establishment for the target cell), after the terminal performs the target uplink transmission, it directly listens to the RAR. For example, the target uplink transmission can be Msg1 or MsgA PRACH. After performing the target uplink transmission, it can start the next random access process, such as receiving Msg2 or MsgB.

[0092] For example, if the function of the target uplink transmission is to request the target cell to send second information and SIB (such as SIB1), after the terminal performs the target uplink transmission, the terminal receives the second information, determines the reception configuration of SIB1 based on the second information, listens for Type 0PDCCH (receives SIB1), and if there is a service to be transmitted, the terminal initiates the random access procedure.

[0093] For example, in the case where the target uplink transmission function is to request the target cell to send second information and an SIB (such as SIB1), and to request access to the target cell (i.e., to initiate connection establishment for the target cell), after the terminal performs the target uplink transmission, it receives the second information, then receives the SIB (such as SIB1), and then listens for the RAR. That is, the target uplink transmission can be Msg1 or MsgA PRACH. After performing the target uplink transmission, the next step of the random access procedure can begin. The order of the second information, the SIB (such as SIB1), and the RAR is not limited. For example, the second information can be received first, and the second information can be configured with the reception configuration of the SIB (such as SIB1). The UE receives the SIB (such as SIB1) based on the reception configuration of the SIB (such as SIB1). After receiving the SIB (such as SIB1), the UE obtains the reception configuration of the RAR based on the SIB (such as SIB1), and then receives the RAR based on the reception configuration of the RAR. For example, the receiving configuration of the second information, the receiving configuration of the SIB (such as SIB1), and the receiving configuration of the RAR can all be placed in the first information. After the UE receives the first information, it can receive the second information, the SIB (such as SIB1), and the RAR based on the configuration in the first information. The order of receiving is not limited and belongs to the UE implementation.

[0094] It should be noted that the target uplink transmission function described in the embodiments of this application can also be referred to as or replaced as: the purpose of the target uplink transmission, or the function of the target uplink transmission, or the attribute of the target uplink transmission.

[0095] In some embodiments, the first operation includes receiving second information.

[0096] Optionally, the second information is information that the target cell transmits non-periodically, or the second information is information transmitted based on a request.

[0097] In this embodiment, the terminal performs the first operation after sending the target uplink transmission, which can be understood as the target cell sending the second information based on the target uplink transmission, or the target uplink transmission request or triggering the target cell to send the second information.

[0098] In some embodiments, the second operation includes, but is not limited to, at least one of the following:

[0099] Receive the second information, listen to the Type 0 Physical Downlink Control Channel (PDCCH), receive the SIB, do not listen to Msg2, do not listen to MsgB, listen to the feedback information of the target uplink transmission, and only listen to the Type 0 PDCCH associated with the SSB associated with the target uplink transmission.

[0100] In this embodiment, the terminal performs the second operation after sending the target uplink transmission, which can be understood as at least one of the following:

[0101] The target cell sends the second information based on the target uplink transmission, or the target uplink transmission request or triggers the target cell to send the second information;

[0102] The target cell sends a Type 0PDCCH (such as the Type 0PDCCH associated with the SSB associated with the target uplink transmission) and a SIB1 scheduled by the Type 0PDCCH based on the target uplink transmission; or, the target uplink transmission triggers the target cell to send a Type 0PDCCH (such as the Type 0PDCCH associated with the SSB associated with the target uplink transmission) and a SIB1 scheduled by the Type 0PDCCH.

[0103] The target cell sends an SIB (such as SIB1) based on the target uplink transmission, or the target uplink transmission request or triggers the target cell to send an SIB (such as SIB1).

[0176] It should be noted that, in this embodiment, the contents of the first information and the second information do not overlap.

Other parameters are similar, and for simplicity, they will not be elaborated further here.

The UE receives SIB1 and determines whether it is allowed to camp in the target cell.

[0184] Optionally, if the duplex mode is configured as FDD, the transmission frequency of the target uplink transmission can be determined based on the Absolute Radio Frequency Channel Number (ARFCN), or the transmission frequency of the target uplink transmission can be determined based on the subcarrier offset (e.g., Kssb) of the SSB relative to CRB 0 or PRB 0, and the offset (offsetToPointA) relative to reference point A. For example, FDD... target =F SSB -kssb-offsetToPointA, where, F target F represents the transmission frequency of the target uplink transmission. SSB This indicates the center frequency of the SSB.

[0185] In some embodiments, a cell bar information can be used to indicate whether the target cell prohibits the terminal's access, or it can be used to indicate whether access to the target cell is allowed. Optionally, the cell bar information includes at least one of the following: terminal characteristics supported by the target cell, combinations of terminal characteristics supported by the target cell, and terminal types supported by the target cell. For example, if the terminal does not meet the terminal characteristics supported by the target cell, the target cell prohibits the terminal's access; if the terminal meets the terminal characteristics supported by the target cell, the target cell allows the terminal's access. As another example, if the terminal does not meet the combination of terminal characteristics supported by the target cell, the target cell prohibits the terminal's access; if the terminal meets the combination of terminal characteristics supported by the target cell, the target cell allows the terminal's access. Yet another example, if the terminal does not meet the terminal type supported by the target cell, the target cell prohibits the terminal's access; if the terminal meets the terminal type supported by the target cell, the target cell allows the terminal's access. The terminal characteristics, or combinations of terminal characteristics, or terminal types include: Reduced Capability (RedCap), Small Data Transmission (SDT), Network Slicing, Extended Reality (XR), Low Power Wide Area (LPWA), Extended Discontinuous Reception (eDRX), Discontinuous Reception (DRX) or Discontinuous Transmission (DTX) in cells, On-Demand SIB1 (OD-SIB1), NES, etc.

[0186] In some embodiments, if the decision threshold for four-step random access is met, the terminal performs four-step random access. For example, four-step random access is performed if the decision threshold is greater than or equal to the four-step random access threshold, or if the decision threshold is less than the four-step random access threshold.

[0187] In some embodiments, the terminal performs two-step random access if the decision threshold for two-step random access is met. For example, two-step random access is performed if the decision threshold is greater than or equal to the decision threshold, or if the decision threshold is less than the decision threshold.

[0188] In some embodiments, independent cell bar information can be introduced for different terminal types, different service types, and different coverage levels.

[0190] Reduced Capability (RedCap) terminals, Low Power Wide Area (LPWA) terminals, and Enhanced Mobile Broadband (eMBB) terminals.

[0191] In some embodiments, intraFreqReselection can be used to indicate whether the target cell prohibits the terminal's access, or intraFreqReselection can be used to indicate whether access to the target cell is allowed.

[0192] In some embodiments, the system frame number is used to determine the SSB burst of the transmission timing when the target uplink transmission occurs.

[0197] Optionally, the cell closest to the target cell that the terminal is allowed to access, indicated by the first or second information, can be a non-energy-saving cell (normal cell). The non-energy-saving cell periodically sends SSB and SIB (such as SIB1). If the target cell prohibits the terminal from accessing, the terminal can try to access the non-energy-saving cell, thereby improving the efficiency of cell access.

[0198] In some embodiments, the first information may also include, but is not limited to, at least one of the following:

[0199] The target uplink transmission configuration corresponding to the target uplink transmission, the relevant information of the second information, and some or all of the information in the second information.

And / or, relevant information of the second information can be obtained through the first information, thereby enabling the second information to be received based on the relevant information of the second information. And / or, some or all of the information in the second information can be obtained through the first information; that is, in this case, only the first information may exist, and the second information may serve as a parameter in the first information.

[0246] Does the second information exist?

[0247] Whether to allow the terminal to request the second information on demand;

[0248] The identifier that allows on-demand requests for the second information;

[0249] The relationship between the second information and the first information;

[0258] The transmission power of the second information;

[0259] The second information is configured for time and frequency resources;

[0260] The relative position information of the second information.

[0261] For example, if the first information indicates that the second information does not exist, or if the first information indicates that the terminal is not allowed to request the second information on demand, in this case, the target cell will not send a second information separately, and the content of the second information will be directly transmitted in the first information, or the SSB of the target cell will not use a two-part transmission architecture for transmission.

[0262] For example, if the first information indicates that the second information does not exist, it means that the UE can send the target uplink transmission and request the transmission of the second information on demand.

[0263] For example, the identifier for the second information that allows on-demand requests can be an SSB identifier. For instance, SSB1, SSB2, and SSB3 are SSBs that allow on-demand requests for the second information, and these SSBs can be split into two parts, first information and second information, for transmission.

[0264] Optionally, the association between the second information and the first information includes at least one of the following:

[0265] The second information is associated with the SSB identifier corresponding to the first information. For example, the first information of the SSB corresponding to an even-numbered identifier has associated second information.

[0267] The type of the second information is associated with the type of the first information;

[0268] The beam identifier of the second information is associated with the beam identifier of the first information;

[0269] The transmission duration of the second information is related to the transmission duration of the first information.

[0271] The frequency at which the second information is transmitted, the time-domain start position of the second information transmission, the transmission period of the second information, the number of transmission periods of the second information, the time-domain offset of the second information in each transmission period, and the duration of the second information transmission.

[0272] In this embodiment, the terminal can receive the second information based on the time-frequency resource configuration of the second information.

[0273] Optionally, the relative position information of the second information includes, but is not limited to, at least one of the following:

[0274] The second information is offset in the time domain relative to the first information, the second information is offset in the time domain relative to the target uplink transmission, and the second information is offset in the frequency domain relative to the first information.

[0275] In this embodiment, the terminal can receive the second information based on the relative position information of the second information.

[0276] In some embodiments, the above-mentioned S230 may specifically include:

[0277] The terminal performs the first target operation according to at least one of the following:

[0278] The first information;

[0279] The terminal measures the results of the first information;

[0280] The target uplink transmission function;

[0281] The characteristics of the target uplink transmission;

[0282] The characteristics of the first information.

[0283] In this embodiment, the terminal can perform a first target operation based on at least one of the following: first information, the terminal's measurement result of the first information, the content of the target uplink transmission, the characteristics of the target uplink transmission, and the characteristics of the first information.

[0284] For example, the terminal can determine the resources (such as time-frequency resources, preamble sequence resources, etc.) of the target uplink transmission based on the measurement results of the first information (such as Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or Signal to Interference plus Noise Ratio (SINR)). Therefore, it can perform the first target operation based on the resources of the target uplink transmission (such as time-frequency resources, preamble sequence resources, etc.). For instance, different reference signal measurement results correspond to different RO resources and different preamble intervals. For example, when RSRP is high, the RO resource allowed to send the target uplink transmission is RO resource 1, and the preamble interval allowed to be used for the target uplink transmission is interval 1. After this target uplink transmission is sent, the UE performs the third operation. In this case, the signal quality of the target cell is good, and after the UE sends the target uplink transmission, it can directly receive Msg2 or MsgB and then continue the random access procedure. For example, when RSRP is low, the RO resource allowed to send the target uplink transmission is RO resource 2, and the preamble interval allowed to be used for the target uplink transmission is interval 2. After this target uplink transmission is sent, the UE performs the second operation. In this case, the signal quality of the target cell is average. After the UE sends the target uplink transmission, it first obtains SIB1 and then determines whether it can directly access the target.

[0285] Optionally, at least one bit in the payload carried by the target uplink transmission can be used to indicate the function of the target uplink transmission. Optionally, the number of bits in the at least one bit can be configured by the network side, or the number of bits in the at least one bit can be agreed upon by the protocol.

[0286] In some embodiments, the features of the target uplink transmission include, but are not limited to, at least one of the following:

[0287] The target uplink transmission configuration corresponding to the target uplink transmission;

[0288] The format of the target uplink transmission;

[0289] The type of uplink transmission to the target;

[0290] The target uplink transmission corresponding sequence resources;

[0291] The transmission timing associated with the target uplink transmission;

[0292] The time and frequency resources occupied by the target uplink transmission.

[0293] For example, if the target uplink transmission function configured in the target uplink transmission configuration is only used to request the SIB of the target cell (such as SIB1), then the target uplink transmission is limited to requesting the SIB of the target cell (such as SIB1).

[0294] For example, it is possible to distinguish whether to request only the second information + SIB (such as SIB1) or to request the second information + SIB (such as SIB1) + connection establishment by using at least two pre-configured indexes of the target uplink transmission configuration.

[0295] For example, at least two pre-configured RO resources or at least two preamble intervals can be used to distinguish whether to request only the second information + SIB (such as SIB1) or to request the second information + SIB (such as SIB1) + connection establishment. This association between the target uplink transmission function and the target uplink transmission resources can be predefined by the protocol or indicated by the network side in the target uplink transmission configuration.

[0296] For example, the target uplink transmission format can be a preamble format or other formats, which are not limited in this application.

[0297] Optionally, the type of the target uplink transmission includes, but is not limited to, at least one of the following:

[0298] Random access related transmissions;

[0299] Upward reference signal (such as SRS);

[0300] Wake-up signal (WUS);

[0301] Uplink request signal.

[0302] Optionally, random access-related transmissions include, but are not limited to, at least one of the following:

[0303] Random access preamble: Msg1, MsgA PRACH, MsgA PUSCH, Msg3.

[0304] Optionally, the sequence resources corresponding to the target uplink transmission include, but are not limited to, at least one of the following:

[0305] The preamble sequence identifier corresponding to the target uplink transmission belongs to the preamble sequence range;

[0306] The preamble sequence format corresponding to the target uplink transmission;

[0307] The type of random access to which the preamble corresponding to the target uplink transmission belongs;

[0308] The random access type includes at least one of the following: two-step random access, four-step random access, contention-based random access, and non-contention-based random access.

[0309] For example, if the preamble index used in the target uplink transmission is in interval 1, the target uplink transmission is only used to request the second information, and the terminal's behavior after executing the target uplink transmission is to perform the first operation; if the preamble index used in the target uplink transmission is in interval 2, the target uplink transmission is only used to request the SIB of the target cell (such as SIB1), and the terminal's behavior after executing the target uplink transmission is to perform the second operation; if the preamble index used in the target uplink transmission is in interval 3, the target uplink transmission is not only used to request the SIB of the target cell (such as SIB1), but also used to initiate connection establishment (random access) and access the target cell, and correspondingly, the terminal's behavior after executing the target uplink transmission is the third operation.

[0310] For example, if the target uplink transmission sent on time-frequency resource configuration 1 is only used to request the SIB of the target cell (such as SIB1), the terminal's behavior after sending the target uplink transmission is to perform the second operation; if the target uplink transmission sent on time-frequency resource configuration 2 is not only used to request the SIB of the target cell (such as SIB1), but also used to initiate connection establishment (random access) and access the target cell, then the terminal's behavior after sending the target uplink transmission is to perform the third operation.

[0311] For example, the target uplink transmission sent on RO resource 1 is to request the second information + SIB (such as SIB1); the target uplink transmission sent on RO resource 2 is to request the second information + SIB (such as SIB1) + initiate connection establishment.

[0380] In this embodiment, the terminal can perform the target uplink transmission based on the relevant parameter set of the target uplink transmission. Optionally, in this embodiment, the terminal can also listen to at least one of the following based on the relevant parameter set of the target uplink transmission: feedback information of the target uplink transmission, Msg2 or RAR, second information, SIB (such as SIB1).

[0381] Optionally, some or all of the parameters in the relevant parameter set for the target uplink transmission can also be agreed upon by the protocol. For example, the subcarrier spacing of the target uplink transmission can be agreed upon by the protocol.

[0382] Optionally, the identifier of the target uplink transmission configuration can be an identifier of the target uplink transmission configuration among at least two uplink transmission configurations, wherein each uplink transmission configuration includes some or all parameters in the relevant parameter set of the target uplink transmission. For example, the network-side device pre-configures at least two uplink transmission configurations, or the protocol stipulates at least two uplink transmission configurations, and the network-side device can indicate an identifier, with the terminal determining the target uplink transmission configuration from the at least two uplink transmission configurations based on the indicated identifier.

[0384] Time slot, microtime slot, subframe, frame, symbol, millisecond, microsecond, second.

[0385] Optionally, the time-domain resource configuration information of the target uplink transmission includes the time-domain offset of the transmission timing of the target uplink transmission relative to the first information and the time-domain length occupied by the transmission timing of the target uplink transmission. In this embodiment, each first information transmitted periodically has an associated transmission timing of the target uplink transmission.

[0386] Optionally, the time-domain resource configuration information of the target uplink transmission includes the period of the target uplink transmission, the offset of the target uplink transmission within each period, and the time-domain length occupied by the transmission timing of the target uplink transmission within each period. In this embodiment, the terminal can periodically perform the target uplink transmission.

[0387] Optionally, the time-domain resource configuration information of the target uplink transmission includes an identifier of at least one specific piece of first information associated with the target uplink transmission, a time-domain offset of the transmission timing of the target uplink transmission relative to the specific piece of first information, and a time-domain length occupied by the transmission timing of the target uplink transmission. In this embodiment, at least one specific piece of first information in the periodically transmitted first information has an associated transmission timing of the target uplink transmission. For example, the odd-numbered bits of the periodically transmitted first information have an associated transmission timing of the target uplink transmission, or the even-numbered bits of the periodically transmitted first information have an associated transmission timing of the target uplink transmission.

[0388] Optionally, the time-domain resource configuration information for the target uplink transmission includes a target time-domain resource configuration index, wherein the target time-domain resource configuration index is used to determine the time-domain resource configuration of the target uplink transmission from at least two candidate time-domain resource configurations for the target uplink transmission. For example, the network-side device may pre-configure at least two candidate time-domain resource configurations for the target uplink transmission, or the protocol may specify at least two candidate time-domain resource configurations for the target uplink transmission.

[0389] Optionally, the frequency domain resource configuration information for the target uplink transmission includes at least one of the following:

[0390] ZeroCorrelationZoneConfig;

[0391] Frequency domain start position (e.g., msg1-FrequencyStart)

[0392] The number of transmission opportunities occupied by the frequency domain (e.g., msg1-FDM);

[0393] The number of SSBs associated with each transmission opportunity;

[0394] SCS during frequency domain transmission;

[0395] The relative frequency domain position of the target uplink transmission is relative to the first information. For example, the time-frequency resources of the target uplink transmission are offset relative to the time-frequency domain of the first information, the time-frequency domain occupancy length of the target uplink transmission, and the frequency band of the target uplink transmission.

[0396] Optionally, the frequency domain resource configuration information for the target uplink transmission includes the frequency domain offset of the transmission timing of the target uplink transmission relative to the first information and the frequency domain length occupied by the transmission timing of the target uplink transmission. In this embodiment, each periodically transmitted first information has an associated transmission timing for the target uplink transmission.

[0397] Optionally, the frequency domain resource configuration information of the target uplink transmission includes the frequency domain offset of the transmission timing of the target uplink transmission relative to the uplink reference point A (UL-Point A) or downlink reference point A (DL-Point A) of the target cell and the frequency domain length occupied by the transmission timing of the target uplink transmission.

[0398] In some embodiments, the wireless communication method 200 further includes:

[0399] The terminal obtains the target uplink transmission configuration corresponding to the target uplink transmission based on at least one of the following:

[0400] The first information, the first association, and the first agreement information;

[0401] Wherein, at least one bit in the first information is used to indicate the target uplink transmission configuration, or at least one information field in the first information is used to indicate the target uplink transmission configuration;

[0402] The first association relationship includes the association relationship between the characteristics of the target cell and the target uplink transmission configuration;

[0403] The first protocol-defined information includes at least one of the following: the time domain position of the target uplink transmission is an offset of a fixed duration relative to the first information (such as an offset at the symbol granularity or a time slot granularity); the frequency domain position of the target uplink transmission is an offset of a fixed length relative to the uplink reference point A (UL point A) or downlink reference point A (DL point A) of the target cell (such as an offset at the resource block (RB) granularity or a subcarrier granularity); and the frequency point of the target uplink transmission is consistent with the frequency point of the SSB of the target cell (such as the center frequency point).

[0404] In this embodiment, the terminal can obtain the target uplink transmission configuration corresponding to the target uplink transmission based on at least one of the first information, the first association relationship, and the first protocol agreement information, so that it can execute the target uplink transmission based on the target uplink transmission configuration. Even the initial search terminal can obtain the target uplink transmission configuration, and then request the transmission of the second information and SIB, and then access the target cell.

[0405] It should be noted that the target uplink transmission configuration obtained based on the first information can be either the specific content of the target uplink transmission configuration or an identifier of the target uplink transmission configuration. Similarly, the target uplink transmission configuration obtained based on the first association relationship can be either the specific content of the target uplink transmission configuration or an identifier that determines the target uplink transmission configuration. Likewise, the target uplink transmission configuration obtained based on the first protocol agreement information can be either the specific content of the target uplink transmission configuration or an identifier that determines the target uplink transmission configuration.

[0406] Optionally, the frequency domain position of the target uplink transmission being an offset of a fixed length relative to the uplink reference point A (ULpointA) or downlink reference point A (DL PointA) of the target cell (such as an offset at the resource block (RB) granularity or a subcarrier granularity) can be pre-configured by the network side or agreed upon by the protocol, and this application does not limit this.

[0407] For example, the at least one bit in the first information can be a newly added bit or a reserved bit. For instance, at least one bit can be a newly added bit or a reserved bit in the Master Information Block (MIB).

[0408] For example, the at least one information field in the first information can be a specific information field in the MIB, such as pdcch-ConfigSIB1 (8 bits) indicating the identifier of the target uplink transmission configuration when kssb=30 or kssb=14.

[0409] For example, on an off-sync raster, the information elements (IEs) in the SSB's MIB can be redefined to explicitly or implicitly indicate the corresponding target uplink transmission configuration or the identifier of the target uplink transmission configuration.

[0410] For example, the protocol stipulates that the time-frequency location of the target uplink transmission is associated with the first information.

[0411] For example, during TDD, the frequency point of the target uplink transmission is consistent with the frequency point (such as the center frequency point) of the SSB of the target cell.

[0412] For example, in FDD, the first information can indicate the frequency domain location of the target uplink transmission; or each band is given a reference point to define the band where the target uplink transmission is located, and the frequency domain location of the target uplink transmission is determined based on the reference point on the corresponding band.

[0413] Optionally, the characteristics of the target cell include, but are not limited to, at least one of the following:

[0414] The synchronization grid where the first information of the target cell is located, the synchronization grid where the SSB center frequency point of the target cell is located, the synchronization grid where the cell frequency point of the target cell is located, the GSCN value, the GSCN value range, the frequency range, the operating frequency band, the transmission period of the SSB, the subcarrier spacing of the SSB, the PCI value, and the PCI value range.

[0415] For example, the synchronization grid where the first information of the target cell is located is associated with the target uplink transmission configuration, and the terminal can obtain the target uplink transmission configuration based on the synchronization grid where the first information is located.

[0416] For example, the synchronization grid where the center frequency of the SSB of the target cell is located is associated with the target uplink transmission configuration, and the terminal can obtain the target uplink transmission configuration based on the synchronization grid where the center frequency of the SSB of the target cell is located.

[0417] For example, the synchronization grid where the cell frequency of the target cell is located is associated with the target uplink transmission configuration, and the terminal can obtain the target uplink transmission configuration based on the synchronization grid where the cell frequency of the target cell is located.

[0418] For example, the GSCN value of the target cell is associated with the target uplink transmission configuration, and the terminal can obtain the target uplink transmission configuration based on the GSCN value of the target cell.

[0419] For example, the GSCN value range of the target cell is associated with the target uplink transmission configuration, and the terminal can obtain the target uplink transmission configuration based on the GSCN value range of the target cell.

[0420] For example, the frequency range of the target cell is associated with the target uplink transmission configuration, and the terminal can obtain the target uplink transmission configuration based on the frequency range of the target cell.

[0421] For example, the operating frequency band of the target cell is associated with the target uplink transmission configuration, and the terminal can obtain the target uplink transmission configuration based on the operating frequency band of the target cell.

[0422] For example, the transmission period of the SSB of the target cell is associated with the target uplink transmission configuration, and the terminal can obtain the target uplink transmission configuration based on the transmission period of the SSB of the target cell.

[0423] For example, the subcarrier spacing of the SSB of the target cell is associated with the target uplink transmission configuration, and the terminal can obtain the target uplink transmission configuration based on the subcarrier spacing of the SSB of the target cell.

[0424] For example, the PCI value of the target cell is associated with the target uplink transmission configuration, and the terminal can obtain the target uplink transmission configuration based on the PCI value of the target cell.

[0425] For example, the PCI value range of the target cell is associated with the target uplink transmission configuration, and the terminal can obtain the target uplink transmission configuration based on the PCI value range of the target cell.

[0426] In some embodiments, the above-described S220 may specifically include:

[0427] The terminal sends the target uplink transmission to the target cell when the first condition is met;

[0428] The first condition includes, but is not limited to, at least one of the following:

[0429] The target cell meets the cell selection criteria;

[0430] The target cell did not prohibit the terminal from accessing;

[0431] The reference signal quality (such as RSRP, RSRQ, or SINR) of the target cell is greater than or equal to a first threshold.

[0432] The terminal's measurement value for the first information (such as RSRP, RSRQ, or SINR) is less than or equal to the second threshold.

[0433] The terminal's measurement value for the first information (such as RSRP, RSRQ, or SINR) is greater than the third threshold, and the terminal's measurement value for the first information (such as RSRP, RSRQ, or SINR) is less than or equal to the fourth threshold.

[0434] The number of repeated transmissions of the target uplink transmission is less than or equal to the fifth threshold.

[0435] The target cell only periodically sends the first information;

[0436] The first information does not include the second information;

[0437] The first information indicates the existence of the second information;

[0438] The terminal could not detect any other suitable cells.

[0439] The target cell is not currently periodically sending SIBs;

[0440] The first information indicates that the terminal is allowed to request the second information as needed;

[0441] The detection energy of the first information is within the first energy range;

[0442] The terminal has a service to be transmitted (such as a request from the terminal's higher layer to establish a Radio Resource Control (RRC) connection);

[0443] The terminal needs to access the target cell;

[0444] The terminal determines to reselect to the target cell.

[0445] In this embodiment, the terminal sends a target uplink transmission to the target cell when the first condition is met. By constraining the terminal's sending of the target uplink transmission to the target cell through the first condition, the rationality of the terminal sending the target uplink transmission to the target cell can be ensured.

[0446] Optionally, the first condition may be pre-configured by the network side, or the first condition may be agreed upon by the protocol, or the first condition may be indicated by the first information.

[0447] For example, it makes sense for the terminal to send a target uplink transmission to wake up the target cell if the reference signal quality of the target cell is greater than or equal to a first threshold. Otherwise, it might be faster to continue searching for SSB signals on other syncrasters.

[0448] For example, if the terminal's measurement value for the first information (such as RSRP, RSRQ, or SINR) is less than or equal to the second threshold, then fine synchronization is required using the second information.

[0449] For example, if the terminal's measurement value for the first information (such as RSRP, RSRQ, or SINR) is greater than a third threshold, and the terminal's measurement value for the first information (such as RSRP, RSRQ, or SINR) is less than or equal to a fourth threshold, then the reliability of the target uplink transmission is ensured. If the terminal's measurement value for the first information (such as RSRP, RSRQ, or SINR) is less than or equal to the fourth threshold, it is determined that a search for the second information needs to be performed. If the terminal's measurement value for the first information (such as RSRP, RSRQ, or SINR) exceeds the fourth threshold, the terminal may abandon the search for the second information.

[0450] For example, if the number of repeated transmissions of the target uplink is less than or equal to the fifth threshold, the target uplink transmission can continue.

[0451] For example, the detection energy of the first information can be divided into the following two cases:

[0452] Case 1: The content of the second information can be contained in the first information, that is, there is only one first information. The terminal can directly send the target uplink transmission and receive the SIB (such as SIB1).

[0453] Scenario 2: The second piece of information is triggered based on the target's uplink transmission;

[0454] In Case 1, the first information specifies 20 PRBs; in Case 2, the first information specifies 12 PRBs. As shown in Table 1, if the subcarrier spacing (SCS) of the SSB is 15 kHz and the energy occupancy of the first information detected by the terminal is 300 kHz, then the terminal considers it to be Case 1, i.e., both the first and second information are being transmitted. Otherwise, the terminal considers only the first information to be transmitted. Under the condition that the first condition is met, the terminal can perform the target uplink transmission.

[0455] Table 1

[0456] Scenario 1 (20 PRBs) Case 2 (12 PRBs) SCS = 15kHz 20 * 15 kHz = 300 kHz 12 * 15 kHz = 180 kHz SCS = 30kHz 20 * 30 kHz = 600 kHz 12 * 30 kHz = 360 kHz

[0457] Optionally, at least one of the first threshold to the fifth threshold may be agreed upon by a protocol, or at least one of the first threshold to the fifth threshold may be configured by the network side, or at least one of the first threshold to the fifth threshold may be indicated by the first information.

[0458] Optionally, the first energy range may be agreed upon by a protocol, or the first energy range may be configured by the network side, or the first energy range may be indicated by the first information.

[0459] In some embodiments, the wireless communication method 200 further includes:

[0460] The terminal receives feedback information transmitted uplink from the target.

[0461] The feedback information is used to indicate at least one of the following:

[0462] The sequence identifier corresponding to the target uplink transmission;

[0463] A positive response (ACK) or a negative response (NACK);

[0473] In this embodiment, the terminal can receive the second information based on the relevant information of the second information.

[0476] The first time unit after the terminal has sent the target uplink transmission X time units, the first PDCCH transmission timing after the terminal has sent the target uplink transmission X time units.

[0477] In this embodiment, after the terminal performs the target uplink transmission, the start time for the terminal to receive the feedback information of the target uplink transmission can be determined, so that the terminal can start receiving the feedback information of the target uplink transmission at the corresponding position.

[0478] Optionally, X is an integer greater than or equal to zero.

[0479] Optionally, X can be agreed upon by a protocol, or X can be pre-configured by the network side, or X can be indicated by the first information.

[0483] The first information, the second information, SIB, the second protocol agreement information, and the target uplink transmission configuration corresponding to the target uplink transmission.

[0484] In this embodiment, the terminal can determine the duration for receiving feedback information of the target uplink transmission based on at least one of the first information, the second information, the SIB, the second protocol agreement information, and the target uplink transmission configuration corresponding to the target uplink transmission, so that it can receive the feedback information of the target uplink transmission within the corresponding duration.

[0485] Optionally, the second protocol agreement information can directly determine the start time for the terminal to receive the feedback information, or the second protocol agreement information can indirectly determine the start time for the terminal to receive the feedback information.

[0486] In some embodiments, the start time for the terminal to initiate a time window for listening to the feedback information includes, but is not limited to, at least one of the following:

[0487] The first time unit after the terminal has sent the target uplink transmission X time units, the first PDCCH transmission timing after the terminal has sent the target uplink transmission X time units.

[0492] In some embodiments, the wireless communication method 200 further includes:

[0493] The terminal receives third information;

[0494] The third information includes, but is not limited to, one of the following: SIB (e.g., SIB1), Msg2, MsgB.

[0495] Optionally, the start time for the terminal to receive the third information includes, but is not limited to, at least one of the following:

[0496] The Y-th time unit after the target reference point, where Y is an integer greater than or equal to zero;

[0497] The timing of the first PDCCH transmission after the target reference point;

[0502] The first PDCCH transmission timing after the first timer expires, wherein the first timer is started at the target reference point.

[0503] In this embodiment, after the terminal sends the target uplink transmission, the starting time domain position for the terminal to receive the third information can be determined, so that the reception of the third information can begin at the corresponding position.

[0504] Optionally, at least one of Y and Z can be agreed upon by a protocol, or at least one of Y and Z can be pre-configured by the network side, or at least one of Y and Z can be indicated by the first information.

[0505] Optionally, the duration and start time of the first timer can be pre-configured by the network-side device, or the duration and start time of the first timer can be indicated by the first information.

[0506] Optionally, the duration for which the terminal receives the third information is determined based on at least one of the following:

[0507] The first information, the second information, the SIB, the fourth protocol agreement information, the feedback information of the target uplink transmission, and the target uplink transmission configuration corresponding to the target uplink transmission.

[0508] In this embodiment, the terminal can determine the duration for receiving the third information based on at least one of the first information, the second information, the SIB, the fourth protocol agreement information, the feedback information of the target uplink transmission, and the target uplink transmission configuration corresponding to the target uplink transmission, so that the terminal can receive the third information within the corresponding duration.

[0509] Optionally, the fourth protocol agreement information can directly determine the duration for which the terminal receives the third information, or the fourth protocol agreement information can indirectly determine the duration for which the terminal receives the third information.

[0510] In some embodiments, the above-mentioned S230 may specifically include:

[0511] The terminal performs the first target operation during the operation of the second timer;

[0512] The second timer is started at the target reference point.

[0513] Optionally, the duration and start time of the second timer can be pre-configured by the network-side device, or the duration and start time of the second timer can be indicated by the first information.

[0514] Optionally, the second timer can be understood as a timer that listens to the SIB (such as SIB1) and RAR or MsgB after the terminal has finished transmitting the target uplink.

[0515] Optionally, the wireless communication method 200 further includes at least one of the following:

[0516] If the terminal does not receive the second information during the second timer's operation, the terminal determines that the second information transmission has failed, and the terminal re-determines whether to send the target uplink transmission.

[0517] If the terminal does not receive a Type 0 PDCCH or a Physical Downlink Shared Channel (PDSCH) carrying an SIB during the second timer operation, the terminal determines that the SIB transmission has failed and the terminal re-determines whether to send the target uplink transmission.

[0518] If the terminal receives SIB and RAR during the operation of the second timer, or if the terminal receives SIB and MsgB during the operation of the second timer, the terminal sends Msg3;

[0519] If the terminal receives SIB and MsgB during the second timer operation, the terminal determines that it has successfully accessed the target cell.

[0520] If the terminal receives an SIB during the second timer's operation, and the terminal does not receive a RAR or MsgB during the second timer's operation, the terminal determines that the SIB transmission was successful and the Random Access Channel (RACH) failed.

[0521] If the terminal receives an SIB during the second timer's operation, and the terminal does not receive a RAR or MsgB during the second timer's operation, the terminal determines that the SIB transmission was successful and the RACH failed, and the terminal re-determines whether to retransmit Msg1 or MsgA (if different from the target uplink transmission).

[0522] In this embodiment, if the terminal does not receive the second information during the second timer operation, the terminal determines that the second information transmission has failed, and the terminal re-determines whether to send the target uplink transmission (e.g., re-determines whether to send the target uplink transmission based on the first condition), thereby ensuring that the second information is received.

[0523] In this embodiment, if the terminal does not receive a Type 0 PDCCH or a PDSCH carrying an SIB (such as SIB1) during the second timer operation, the terminal determines that the SIB (such as SIB1) transmission has failed, and the terminal re-determines whether to send the target uplink transmission (such as re-determining whether to send the target uplink transmission based on the first condition), thereby ensuring that the SIB (such as SIB1) is received.

[0524] In this embodiment, if the terminal receives SIB and RAR during the second timer operation, or if the terminal receives SIB and MsgB during the second timer operation, the terminal sends Msg3, thereby enabling normal random access to access the target cell.

[0525] In this embodiment, if the terminal receives SIB and MsgB during the second timer operation, the terminal can determine that it has successfully accessed the target cell, and thus can perform the corresponding services in the target cell.

[0526] In this embodiment, if the terminal receives an SIB during the second timer operation, and the terminal does not receive a RAR or MsgB during the second timer operation, the terminal determines that the SIB transmission was successful and the RACH failed, thereby enabling it to promptly obtain the random access status.

Figure 8 The network-side embodiments of this application are described in detail below. It should be understood that the network-side embodiments correspond to the terminal-side embodiments, and similar descriptions can be found in the terminal-side embodiments.

[0573] In this embodiment, the second target operation includes one of the fourth, fifth, and sixth operations. This can be understood as follows: the network-side device is aware in advance that it may perform the fourth, fifth, or sixth operation, and then performs one of the fourth, fifth, or sixth operations based on the actual situation. Alternatively, in this embodiment, the second target operation including one of the fourth, fifth, and sixth operations can also be understood as the network-side device performing the fourth operation, the fifth operation, or the sixth operation based on the actual situation.

[0574] The first information described in the embodiments of this application may include part or all of the contents of a Synchronization Signal Block (SSB). Optionally, if the first information includes part of the contents of an SSB, the first information may also be referred to as a first-level SSB, a first part of an SSB, or a first partial SSB, or other similar names. The first information may also include other content besides part of the contents of an SSB, and this application is not limited in this regard. Optionally, if the first information includes all of the contents of an SSB, the first information may also be referred to as an SSB, or other similar names. The first information may also include other content besides all of the contents of an SSB, and this application is not limited in this regard.

[0575] The second information described in this application embodiment can be information sent aperiodically by the target cell, or it can be information sent based on a request. For example, the target cell sends the second information based on a target uplink transmission, or a target uplink transmission request triggers the target cell to send the second information.

[0576] The second information described in the embodiments of this application may include a portion of the content of an SSB. The second information may also be referred to as a second-level SSB, a second part of an SSB, or a second part of an SSB, or other similar names. The second information may also include other content besides a portion of the content of an SSB, and this application does not limit this.

[0577] The first information described in the embodiments of this application may also be referred to as a reference signal and / or system information block, and the second information described in the embodiments of this application may also be referred to as a reference signal and / or system information block. This application does not limit this.

[0578] The SIBs described in the embodiments of this application include at least SIB1, but may also include other SIBs, and this application does not limit them.

[0579] The SSB described in this application embodiment can also be called any signal set or signal module that includes at least one of the following: synchronization signal, broadcast signal, PBCH, other system message downlink broadcast channel and its control channel, or control resource set, or control channel search space.

[0580] In some embodiments, the target uplink transmission function includes, but is not limited to, one of the following:

[0581] Request to remain in the target cell;

[0582] Request the target cell to send the second information;

[0583] Request the target cell to send an SIB;

[0584] The target cell is requested to send the second information and SIB;

[0585] Request access to the target cell;

[0586] The system requests the target cell to send second information and requests access to the target cell.

[0587] The system requests the target cell to send an SIB and requests access to the target cell.

[0588] The system requests the target cell to send the second information and SIB, and requests access to the target cell.

[0589] In this embodiment, the network-side device can perform corresponding operations based on the target uplink transmission function.

[0590] For example, if the function of the target uplink transmission is to request the target cell to send second information, and if the second information contains the information necessary for the terminal to camp on the target cell, after the terminal performs the target uplink transmission, it receives the second information and can first determine whether the target cell allows the terminal to camp on the target cell based on the second information.

[0591] For example, if the function of the target uplink transmission is to request the target cell to send an SIB (such as SIB1), after the terminal performs the target uplink transmission, the terminal listens for Type 0PDCCH (receives SIB1), and if there is a service to be transmitted, the terminal initiates the random access procedure.

[0592] For example, if the target uplink transmission function is to request the target cell to send an SIB (such as SIB1) and to request access to the target cell (i.e., to initiate connection establishment for the target cell), after the terminal performs the target uplink transmission, it directly listens to the RAR. For example, the target uplink transmission can be Msg1 or MsgA PRACH. After performing the target uplink transmission, it can start the next random access process, such as receiving Msg2 or MsgB.

[0593] For example, if the function of the target uplink transmission is to request the target cell to send second information and SIB (such as SIB1), after the terminal performs the target uplink transmission, the terminal receives the second information, determines the reception configuration of SIB1 based on the second information, listens for Type 0PDCCH (receives SIB1), and if there is a service to be transmitted, the terminal initiates the random access procedure.

[0594] For example, if the function of the target uplink transmission is to request the target cell to send the second information and SIB (such as SIB1), and to request access to the target cell (i.e., to initiate the connection establishment for the target cell), after the terminal performs the target uplink transmission, the terminal receives the second information, then receives the SIB (such as SIB1), and then listens for RAR. That is, the target uplink transmission can be Msg1 or MsgA PRACH. After performing the target uplink transmission, the terminal can start the next random access process, such as receiving Msg2 or MsgB.

[0595] It should be noted that the target uplink transmission function described in the embodiments of this application can also be referred to as or replaced as: the purpose of the target uplink transmission, or the function of the target uplink transmission, or the attribute of the target uplink transmission.

[0596] In some embodiments, the fourth operation includes sending second information.

[0597] In some embodiments, the fifth operation includes, but is not limited to, at least one of the following:

[0598] Send the second information, send type 0PDCCH, send SIB, send the feedback information of the target uplink transmission, and only send type 0PDCCH associated with the SSB associated with the target uplink transmission.

[0599] It should be noted that the execution order of the steps in the fifth operation is not limited in the embodiments of this application.

[0600] In some embodiments, the sixth operation includes, but is not limited to, at least one of the following:

[0601] Send the second message, send a PDCCH of type 0, send a DCI scrambled by RA-RNTI, send RAR, send a DCI scrambled by MsgB-RNTI, send a PDCCH scrambled by SI-RNTI, send MsgB, send Msg2, receive Msg3, and send Msg4.

[0736] Optionally, the candidate locations for the second information include time-frequency locations;

[0737] The time-frequency position includes at least one of the following:

[0738] The first information of the time-domain distance consists of R1 symbols, and R1 is indicated by the first information;

[0739] The frequency point in the frequency domain is the same as the frequency point of the first information, or the frequency point in the frequency domain is offset from the frequency point of the first information by R2 GSCN values ​​or R3 sync raster values.

[0740] Number of symbols or time slots occupied in the time domain;

[0741] The number of RBs or subcarriers occupied in the frequency domain.

The UE may optionally receive the feedback information of the target uplink transmission.

[0747] S1-3. Based on the indication of the first information, the UE receives the second information at the location of the nearest candidate second information after the target uplink transmission, and decodes the second information.

[0748] S1-4. The UE determines the SIB1 reception configuration based on the first information and the second information. The UE starts receiving SIB1 at the most recent Type 0 PDCCH transmission time (starts the OD-SIB1 listening window), the duration of which is agreed upon by the protocol or determined by the target uplink transmission configuration; the UE starts the Msg2 listening window at the end of the OD-SIB1 listening window; the duration of the Msg2 listening window is either indicated by the target uplink transmission configuration or indicated in OD-SIB1.

[0749] S1-5. Based on the received SIB1, the UE determines the reception configuration of Msg2, listens for Msg2 within the Msg2 listening window, and stops the Msg2 listening window when Msg2 is detected.

[0750] S1-6. If the conditions are met, send Msg3.

[0751] S1-7. Received Msg4, successfully accessed the target cell.

[0752] Example 2 details the technical solution of this application using target uplink transmission combined with four-step random access as an example.

[0753] The difference from Embodiment 1 is that Msg2 is not only step 2 in the random access process, but also the feedback information of the target uplink transmission; while in Embodiment 1, Msg2 is only step 2 in the random access process.

[0754] like Figure 10 As shown, the specific process of Embodiment 2 may include some or all of S2-1 to S2-7.

[0911] Example 7 details the technical solution of this application by taking the target uplink transmission with different functions distinguished between the network side and the UE as an example.

[0912] Optionally, the target uplink transmission function includes, but is not limited to, one of the following:

[0913] Request to remain in the target cell;

[0914] Request the target cell to send the second information;

[0915] Request the target cell to send an SIB;

[0916] The target cell is requested to send the second information and SIB;

[0917] Request access to the target cell;

[0918] The system requests the target cell to send second information and requests access to the target cell.

[0919] The system requests the target cell to send an SIB and requests access to the target cell.

[0920] The system requests the target cell to send the second information and SIB, and requests access to the target cell.

[0921] Optionally, the function of the target uplink transmission can be distinguished by the resource configuration of the target uplink transmission;

[0922] The resource configuration for the target uplink transmission can be determined by the first information and / or the second information and / or some parameters predefined by the network side.

[0923] For example, different preambles correspond to different target uplink transmission functions.

[0924] For example, different ROs correspond to different target uplink transmission functions.

[0925] For example, it can be determined whether a UE is allowed to directly perform cell access procedures based on the target uplink transmission, depending on whether a separate RO resource is configured.

[0926] For example, whether a UE is allowed to directly perform a cell access procedure based on a target uplink transmission can be determined based on whether the Msg A resource is configured.

[0927] For example, different preamble formats correspond to different target uplink transmission functions.

[0928] For example, the MsgA resource is used for a specific function, and the Msg1 resource is used for other specific functions.

[0929] For example, Msg1 indicates that the UE expects to directly access the target cell; MsgA indicates that the UE only requests SIB1.

[0930] Optionally, the target uplink transmission function can be explicitly or implicitly indicated directly through the first information.

[0931] For example, the PBCH of the first information can be used to explicitly indicate whether the function of UE directly accessing the cell based on the target uplink transmission is supported.

[0932] For example, the target uplink transmission function can be determined based on the frequency point / band / sync raster / GSCN value where the first information is located.

[0933] For example, if the first information is in sync raster 1, it means that the target uplink transmission can only trigger SIB1 transmission; if the first information is in sync raster 2, it means that the target uplink transmission can not only trigger SIB1 transmission, but also directly trigger the random access procedure based on the target uplink transmission.

[0934] For example, if the first information is FR1, it means that the target uplink transmission can only trigger SIB1 transmission; if the first information is FR2, the target uplink transmission can not only trigger SIB1 transmission, but also directly trigger the random access procedure based on the target uplink transmission.

[0935] In Example 7, the UE is provided with configuration resources for target uplink transmissions with different functions, such as requesting only SIB1, or requesting not only SIB1 but also expecting to access the target cell. Based on the requirements, the UE selects appropriate resources for target uplink transmissions to send the target uplink transmission.
