[0094] 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).
[0095] In this embodiment, after the terminal receives the first information from the target cell—in other words, after the terminal searches for the target cell—the terminal can use the first information to determine whether the target cell is a cell that prohibits the terminal from accessing, or whether the target cell allows the terminal to request the second information and SIB by sending a target uplink transmission, or whether the target cell periodically sends the first information, the second information, and the SIB. Thus, the terminal can selectively perform either the first operation or the second operation. For the first operation, the terminal that initially searches can also access the target cell. For the second operation, the terminal that initially searches can avoid receiving unnecessary second information, or the terminal that initially searches can avoid receiving unnecessary second information and SIB, thereby reducing the power consumption of the terminal that initially searches. If the target cell is a cell that allows terminal access, or if the target cell allows the terminal to request the second information and SIB by sending a target uplink transmission, the terminal can send the target uplink transmission and receive the second information and SIB, thereby obtaining the second information and SIB in a timely manner; if the target cell is a cell that allows terminal access, or if the target cell allows the terminal to request the SIB by sending a target uplink transmission, the terminal can send the target uplink transmission and receive the SIB.
[0096] In some embodiments, the terminal may also determine whether the target cell is a cell that prohibits the terminal from accessing through blind detection or protocol-defined information; or, the terminal may also determine whether the target cell is a cell that allows the terminal to request the second information and SIB by sending the target uplink transmission through blind detection or protocol-defined information; or, the terminal may also determine whether the target cell is a cell that allows the terminal to request the SIB by sending the target uplink transmission through blind detection or protocol-defined information; or, the terminal may also determine whether the target cell is a cell that periodically sends the first information, the second information, and the SIB through blind detection or protocol-defined information.
[0097] 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.

[0098] 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.
[0099] 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.
[0100] 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.
[0101] The non-receiving of the second information described in this application embodiment can be understood as: the terminal has been receiving the second information all along, or the terminal has been expecting or waiting to receive the second information all along, and is now skipping the reception of the second information, or is not currently receiving the second information, or the network side is currently sending the second information but the terminal is not receiving the second information, or the network side is currently not sending the second information.
[0102] The non-receiving of SIBs described in this application embodiment can be understood as: the terminal has been receiving SIBs all along, or the terminal has been expecting or waiting to receive SIBs all along and is now skipping the receiving of SIBs, or the terminal is not receiving SIBs at present, or the network side is sending SIBs but the terminal is not receiving SIBs, or the network side is not sending SIBs at present.
[0103] 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.
[0104] 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.
[0105] 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.
[0106] 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.
[0107] 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.
[0108] For example, the first information or the second information can be as follows: Figure 7 As shown, in Figure 7In 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.
[0109] 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.
[0110] 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.
[0111] It should be noted that the units of frequency domain resources in the above figure can be resource blocks (RB), PRB, common resource blocks (CRB), or subcarriers, etc.
[0112] 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.
[0113] In some embodiments, the target uplink transmission includes, but is not limited to, at least one of the following:
[0114] The random access preamble, message 1 (Msg1) during the random access process, message A (MsgA) during the random access process, Physical Random Access Channel (PRACH), Physical Uplink Shared Channel (PUSCH) for MsgA, message 3 (Msg3) during the random access process, Sounding Reference Signal (SRS), specific uplink wake-up signal (WUS) or specific uplink request signal.
[0115] In some embodiments, the target uplink transmission function includes one of the following:
[0116] Request the target cell to send the second information;
[0117] Request the target cell to send an SIB;
[0118] The target cell is requested to send the second information and SIB.
[0119] In this embodiment, the network-side device can perform corresponding operations based on the target uplink transmission function.
[0120] 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.
[0121] 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.
[0122] 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.
[0123] 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.

[0151] It should be noted that, in this embodiment, the contents of the first information and the second information do not overlap. For example, if the first information includes an offset (offsetToPointA) relative to reference point A, then the second information does not include the offset (offsetToPointA) of reference point A. Other parameters are similar, and for simplicity, they will not be elaborated further here. If the contents of the first information and the second information overlap, the most recently received content shall prevail.
[0152] In some embodiments, the first information and the second information can be combined into one information, that is, the network side periodically broadcasts the information, the UE receives the information, and sends a target uplink transmission request SIB1 to the target cell if the conditions are met. The UE receives SIB1 and determines whether it is allowed to camp in the target cell.

[0158] Optionally, if the duplex mode is configured as TDD, the transmission frequency of the target uplink transmission can be the center frequency of the SSS.
[0159] 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.

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.

[0221] 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, then it means that the UE cannot access the cell.
[0222] 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.

[0302] 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.
[0303] 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 odd-numbered first pieces of information in the periodically transmitted first piece of information have an associated transmission timing of the target uplink transmission, or the even-numbered first pieces of information in the periodically transmitted first piece of information have an associated transmission timing of the target uplink transmission. For example, in the target uplink transmission configuration, the SSBs (first pieces of information) indicating SSB indices 1, 3, and 5 have associated transmission timings of the target uplink transmission, while the SSBs (first pieces of information) with the other SSB indices do not have associated transmission timings of 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.

[0314] The number of SSBs associated with each transmission opportunity;
[0315] SCS during frequency domain transmission;
[0316] 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.
[0317] 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.

[0319] In some embodiments, the transmission frequency of the target uplink transmission is determined based on at least one of the following:
[0320] Offset value relative to the first target reference point;
[0321] The first information indicates the ARFCN value corresponding to the target uplink transmission;
[0322] The frequency points for the target uplink transmission as agreed in the protocol;

[0329] The TRP corresponding to the first information.
[0330] In this embodiment, the terminal can determine the transmission frequency of the target uplink transmission based on the offset value of the transmission frequency of the target uplink transmission relative to the first target reference point. Optionally, the offset value relative to the first target reference point can be 0, that is, the transmission frequency of the target uplink transmission is consistent with the first target reference point.
[0331] Optionally, the offset value relative to the first target reference point can be indicated by the first information, or the offset value relative to the first target reference point can be agreed upon by the protocol.
[0332] In this embodiment, the terminal can determine the transmission frequency of the target uplink transmission based on the ARFCN value corresponding to the target uplink transmission.
[0333] In this embodiment, the terminal can determine the target uplink transmission frequency point agreed upon in the protocol as the target uplink transmission transmission frequency point.
[0334] In this embodiment, the terminal can determine the transmission frequency of the target uplink transmission based on the subcarrier offset (e.g., Kssb) of SSB relative to CRB 0 or PRB 0 and the offset (offsetToPointA) relative to reference point A. For example, F 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.
[0335] In this embodiment, the terminal can determine the transmission frequency of the target uplink transmission based on at least one of the following: the synchronization grid where the first information is located, the transmission period of the first information, the bandwidth corresponding to the first information, the frequency range corresponding to the first information, the carrier corresponding to the first information, and the TRP corresponding to the first information.
[0336] For example, the sync raster containing the first information is associated with the transmission frequency of the target uplink transmission. For instance, different sync rasteres containing the first information may be associated with different transmission frequencies of the target uplink transmission; this association can be one-to-one or one-to-many. If the sync raster containing the first information is associated with at least two transmission frequencies of the target uplink transmission, the first information can indicate the specific transmission frequency used. For example, if the first information is specified on sync raster 1, the target uplink transmission is transmitted on band 1; if the first uplink signal is specified on sync raster 2, the target uplink transmission is transmitted on band 2.
[0337] For example, the transmission period of the first information is associated with the transmission frequency of the target uplink transmission. For instance, different transmission periods of the first information are associated with different transmission frequencies of the target uplink transmission, and the association can be one-to-one or one-to-many. If the transmission period of the first information is associated with at least two transmission frequencies of the target uplink transmission, the first information can indicate the specific transmission frequency used.
[0338] For example, the bandwidth corresponding to the first information is associated with the transmission frequency of the target uplink transmission. For instance, different first information corresponds to different bandwidths of the target uplink transmission, and the association can be one-to-one or one-to-many. If the bandwidth corresponding to the first information is associated with at least two target uplink transmission frequencies, the first information can indicate the specific transmission frequency used.
[0339] For example, the frequency range corresponding to the first information is associated with the transmission frequency of the target uplink transmission. For instance, different frequency ranges corresponding to the first information are associated with different transmission frequencies of the target uplink transmission, and the association can be one-to-one or one-to-many. If the frequency range corresponding to the first information is associated with at least two transmission frequencies of the target uplink transmission, the first information can indicate the specific transmission frequency used.
[0340] For example, the carrier corresponding to the first information is associated with the transmission frequency of the target uplink transmission. For instance, different carriers corresponding to the first information are associated with different transmission frequencies of the target uplink transmission, and the association can be one-to-one or one-to-many. If the carrier corresponding to the first information is associated with at least two transmission frequencies of the target uplink transmission, the first information can indicate the specific transmission frequency used.
[0341] For example, the TRP corresponding to the first information is associated with the transmission frequency of the target uplink transmission. For instance, different TRPs corresponding to the first information are associated with different transmission frequencies of the target uplink transmission, and the association can be one-to-one or one-to-many. If the TRP corresponding to the first information is associated with at least two transmission frequencies of the target uplink transmission, the first information can indicate the specific transmission frequency used.
[0342] Optionally, the first target reference point may include, but is not limited to, one of the following:
[0343] The center frequency point (or subcarrier) corresponding to the first information, the lowest frequency point (or subcarrier) corresponding to the first information, the highest frequency point (or subcarrier) corresponding to the first information, and the fixed frequency domain position agreed upon in the protocol (such as ARFCN value or Global synchronization channel number (GSCN) number).
[0344] In some embodiments, if the terminal performs the first operation in S220 above, the wireless communication method 200 further includes:
[0345] The terminal determines whether the second information or the SIB has started transmitting based on at least one of the following:
[0346] Whether the terminal blindly detects the second information or the SIB;
[0347] Whether the terminal blindly detects feedback information of the target uplink transmission sent by other terminals;
[0348] The energy level of the first information detected by the terminal;
[0349] The frequency domain range corresponding to the first information;
[0350] The GSCN value range corresponding to the first information;
[0351] Whether the first information is located in the synchronization grid;
[0352] Subcarrier spacing of SSB;
[0353] The reference signal in the first information indicates;
[0354] The PCI indication in the first information;
[0355] The correlation between the first information and the network state, or the correlation between the values of some information elements in the first information and the network state;
[0356] The network status includes energy-saving status and non-energy-saving status.
[0357] In this embodiment, the terminal determines whether the second information or the SIB has started transmission based on whether it has blindly detected it. For example, if the terminal blindly detects the second information, then the second information has started transmission; or, if the terminal blindly detects the SIB, then the SIB has started transmission. If the second information or the SIB has started transmission, the terminal does not need to perform the target uplink transmission.
[0358] In this embodiment, the terminal determines whether the second information or the SIB has started transmission based on the detected energy level of the first information. For example, if the energy level of the first information detected by the terminal does not exceed a specific value, it indicates that the second information or the SIB has not started transmission; if the energy level of the first information detected by the terminal exceeds a specific value, it indicates that the second information or the SIB has started transmission. For another example, if the first information does not contain the second information, the energy level of the first information detected by the terminal is 3.6 joules; if the first information contains the second information, the energy level of the first information detected by the terminal is 4.8 joules. If the second information or the SIB has started transmission, the terminal does not need to perform the target uplink transmission.
[0359] In this embodiment, the terminal determines whether the second information or SIB has started transmission based on the frequency domain range corresponding to the first information. Optionally, the frequency domain range corresponding to the first information is associated with the network status; wherein, if the network status associated with the frequency domain range corresponding to the first information is in an energy-saving state, the second information or SIB has not started transmission; if the network status associated with the frequency domain range corresponding to the first information is in a non-energy-saving state, the second information or SIB has started transmission.
[0360] In this embodiment, the terminal determines whether the second information or SIB has started transmission based on the GSCN value range corresponding to the first information. Optionally, the GSCN value range corresponding to the first information is associated with the network status; wherein, if the network status associated with the GSCN value range corresponding to the first information is in an energy-saving state, it indicates that the second information or SIB has not started transmission; if the network status associated with the GSCN value range corresponding to the first information is in a non-energy-saving state, it indicates that the second information or SIB has started transmission.
[0361] In this embodiment, the terminal determines whether the second information or SIB has started transmission based on whether the first information is located in a synchronization raster. Optionally, whether the first information is located in a synchronization raster is associated with the network state; wherein, if the first information is located in network state 1 associated with a synchronization raster, it indicates that the second information or SIB has not started transmission; if the first information is located in network state 2 associated with an off-sync raster, it indicates that the second information or SIB has started transmission, such as if the first information already contains the second information and / or SIB.
[0362] In this embodiment, the terminal determines whether the second information or SIB has started transmission based on the SSB subcarrier spacing. Optionally, if the SSB subcarrier spacing is the first subcarrier spacing, the terminal is allowed to send a target uplink transmission request to wake up the target cell, and the second information or SIB has not started transmission; if the SSB subcarrier spacing is the second subcarrier spacing, the second information or SIB has started transmission. For example, the first subcarrier spacing is 30kHz, and the second subcarrier spacing is 15kHz.
[0363] In some embodiments, the reference signal in the first information indicates whether the second information or the SIB has started transmitting, including at least one of the following:
[0364] The network status associated with DMRS in the first information indicates whether the second information or the SIB has started transmitting;
[0365] The network status associated with the PSS in the first information indicates whether the second information or the SIB has started sending;
[0366] The network status associated with the SSS in the first information indicates whether the second information or the SIB has started sending;
[0367] The network status associated with the relative positions of the DMRS and PSS in the first information indicates whether the second information or the SIB has started transmitting;
[0368] The network status associated with the relative positions of the SSS and PSS in the first information indicates whether the second information or the SIB has started sending.
[0369] In this embodiment, the terminal can determine whether the second information or SIB has started transmission based on the network status associated with the DMRS in the first information. For example, if the network status associated with the DMRS in the first information is in an energy-saving state, the second information or SIB has not started transmission; if the network status associated with the DMRS in the first information is in a non-energy-saving state, the second information or SIB has started transmission.
[0370] In this embodiment, the terminal can determine whether the second information or SIB has started sending based on the network status associated with the PSS in the first information. For example, if the network status associated with the PSS in the first information is in an energy-saving state, the second information or SIB has not started sending; if the network status associated with the PSS in the first information is in a non-energy-saving state, the second information or SIB has started sending.
[0371] In this embodiment, the terminal can determine whether the second information or SIB has started sending based on the network status associated with the SSS in the first information. For example, if the network status associated with the SSS in the first information is in an energy-saving state, the second information or SIB has not started sending; if the network status associated with the SSS in the first information is in a non-energy-saving state, the second information or SIB has started sending.
[0372] In this embodiment, the terminal can determine whether the second information or SIB has started transmission based on the network status associated with the relative positions of DMRS and PSS in the first information. For example, if the network status associated with the relative positions of DMRS and PSS in the first information is in an energy-saving state, the second information or SIB has not started transmission; if the network status associated with the relative positions of DMRS and PSS in the first information is in a non-energy-saving state, the second information or SIB has started transmission.
[0373] In this embodiment, the terminal can determine whether the second information or SIB has started transmission based on the network status associated with the relative positions of SSS and PSS in the first information. For example, if the network status associated with the relative positions of SSS and PSS in the first information is in an energy-saving state, the second information or SIB has not started transmission; if the network status associated with the relative positions of SSS and PSS in the first information is in a non-energy-saving state, the second information or SIB has started transmission.
[0374] In some embodiments, the reference signal in the first information indicates whether the second information or the SIB has started transmitting, including at least one of the following:
[0375] The PBCH payload in the first message indicates whether the second message or the SIB has started transmitting;
[0376] The physical layer of the PBCH in the first message indicates whether the second message or the SIB has started transmitting;
[0377] The subcarrier offset of the SSB relative to CRB 0 or the subcarrier offset of the SSB relative to PRB 0 in the first information indicates whether the second information or the SIB has started transmission.
[0378] In this embodiment, the terminal can determine whether the second information or SIB has started to be transmitted based on the PBCH payload indication in the first information.
[0379] In this embodiment, the terminal can determine whether the second information or SIB has started to be transmitted based on the physical layer indication of the PBCH in the first information.
[0380] In this embodiment, the terminal can determine whether the second information or SIB has started transmission based on the subcarrier offset (e.g., kssb) of the SSB relative to CRB 0 or PRB 0 in the first information. For example, when kssb is within a specific range, the terminal can send the target uplink transmission request second information and the SIB, that is, the second information or SIB has not started transmission. Optionally, when kssb is within a specific range, pdcch-ConfigSIB1 can be used to determine the target uplink transmission configuration.
[0381] In some embodiments, the PCI in the first information indicates whether the second information or the SIB has started transmitting, including:
[0382] The network status associated with the PCI in the first information indicates whether the second information or the SIB has started sending.
[0383] In this embodiment, the terminal can determine whether the second information or SIB has started transmission based on the network status associated with the PCI in the first information. For example, if the network status associated with the PCI in the first information is in power-saving mode, the second information or SIB has not started transmission; if the network status associated with the PCI in the first information is in non-power-saving mode, the second information or SIB has started transmission. Optionally, the PCI can be determined based on PSS and SSS.
[0384] In some embodiments, the terminal can determine whether the second information or SIB has started to be transmitted based on whether feedback information corresponding to the target uplink transmission triggered by other terminals is blindly detected. For example, the feedback of all target uplink transmissions is scrambled by a common RNTI. Before transmitting the target uplink transmission, the terminal first searches for the feedback of the target uplink transmission in a specific search space (SS) (such as a common search space configured on the network side). If the RAR corresponding to the target uplink transmission sent by other terminals can be found in the specific SS, the terminal considers that the second information and SIB (such as SIB 1) have been triggered by other terminals, and there is no need to transmit the target uplink transmission again.
[0385] In some embodiments, the wireless communication method 200 further includes:
[0386] The terminal obtains the target uplink transmission configuration corresponding to the target uplink transmission based on at least one of the following:
[0387] The first information, the first association, and the first agreement information;
[0388] 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;
[0389] The first association relationship includes the association relationship between the characteristics of the target cell and the target uplink transmission configuration;
[0390] 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 the downlink reference point A (DL point A) (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).
[0391] 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.
[0392] 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.
[0393] Optionally, the frequency domain position of the target uplink transmission can be offset by a fixed length relative to the uplink reference point A (UL point A) or the downlink reference point A (DL point A) (such as an offset at the resource block (RB) granularity or a subcarrier granularity). This can also be pre-configured by the network side or agreed upon by the protocol, and this application does not limit this.
[0394] 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).
[0395] 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.
[0396] 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.
[0397] For example, the protocol stipulates that the time-frequency location of the target uplink transmission is associated with the first information.
[0398] 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.
[0399] 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.
[0400] Optionally, the characteristics of the target cell include, but are not limited to, at least one of the following:
[0401] 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.
[0402] 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.
[0403] 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.
[0404] 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.
[0405] 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.
[0406] 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.
[0407] 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.
[0408] 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.
[0409] 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.
[0410] 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.
[0411] 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.
[0412] 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.
[0413] In some embodiments, the time-frequency resource configuration of the second information is determined based on at least one of the following:
[0414] The first information, the second association, the identifier of the target cell, the PCI value of the target cell, and the second protocol agreement information;
[0415] The second association relationship includes, but is not limited to, at least one of the following:
[0416] The relationship between terminal type and time-frequency resource configuration of the second information, the relationship between terminal characteristics and time-frequency resource configuration of the second information, the relationship between terminal function and time-frequency resource configuration of the second information, and the relationship between time-frequency resource configuration of the first information and time-frequency resource configuration of the second information.
[0417] In this embodiment, the terminal can determine the time-frequency resource configuration of the second information based on the first information, the second association relationship, the identifier of the target cell, the PCI value of the target cell, and the second protocol agreement information, thereby enabling it to receive the second information.
[0418] For example, the first information may directly indicate at least one of the following: the sync raster identifier corresponding to the second information, the band identifier corresponding to the second information, the TRP identifier corresponding to the second information, and the carrier identifier corresponding to the second information.
[0419] For example, the second information and the first information may or may not be on the same sync raster. For instance, the sync raster where the second information is located can be determined based on the sync raster where the first information is located.
[0420] For example, the terminal type is associated with the time-frequency resource configuration of the second information, and the terminal can determine the time-frequency resource configuration of the second information based on its terminal type. For instance, a Low Power Wide Area (LPWA) UE only transmits the target uplink transmission on frequency band 1 and receives the second information only on synchronization grid 1; an Enhanced Mobile Broadband (eMBB) UE only transmits the target uplink transmission on frequency band 2 and receives the second information only on synchronization grid 2; wherein, synchronization grid 1 can be sparser than synchronization grid 2, which is beneficial for the initial search of LPWA UEs.
[0421] For example, the terminal may obtain the identifier of the target cell based on the first information, and the terminal may determine the offset between the time-frequency resource location of the second information and the time-frequency resource location of the first information based on the identifier of the target cell.
[0422] For example, the terminal may obtain the PCI value of the target cell based on the first information, and the terminal may determine the time-frequency resource configuration of the second information or the offset between the time-frequency resource location of the second information and the time-frequency resource location of the first information based on the PCI value of the target cell.
[0423] For example, the terminal can determine the offset between the time-frequency resource location of the second information and the time-frequency resource location of the first information based on the PSS sequence or SSS sequence in the first information.
[0424] Optionally, the second protocol-defined information can directly determine the time-frequency resource configuration of the second information, or the second protocol-defined information can indirectly determine the time-frequency resource configuration of the second information.
[0425] In some embodiments, if the terminal performs the first operation in S220 above, the start time for the terminal to receive the second information or the SIB after the terminal sends the target uplink transmission includes at least one of the following:
[0426] The X1th time unit after the second target reference point;
[0427] The Y1st PDCCH transmission timing is after the X2th time unit following the second target reference point;
[0428] The first symbol of the Y2th control resource set after the X3rd time unit following the second target reference point;
[0429] The PDCCH transmission timing corresponding to the SSB associated with the target uplink transmission, after the X4th time unit following the second target reference point;
[0430] The first symbol of the control resource set corresponding to the SSB associated with the uplink transmission of the target, which is the Y4th time unit after the X5th time unit following the second target reference point;
[0431] The temporal location of the first piece of the second information after the second target reference point;
[0432] The Y1st PDCCH transmission timing after the first timer expires, or the first symbol of the Y2th control resource set after the first timer expires, or the Y3rd PDCCH transmission timing corresponding to the SSB associated with the target uplink transmission after the first timer expires, or the first symbol of the control resource set corresponding to the SSB associated with the target uplink transmission after the first timer expires.
[0433] The first timer is started at the target reference point, and X1, X2, X3, X4, X5, Y1, Y2, Y3, and Y4 are integers greater than or equal to zero.
[0434] In this embodiment, after the terminal sends the target uplink transmission, the start time for the terminal to receive the second information or SIB can be determined, so that the reception of the second information or SIB can begin at the corresponding location.
[0435] Optionally, at least one of X1, X2, X3, X4, X5, Y1, Y2, Y3, Y4 can be agreed upon by the protocol, or at least one of X1, X2, X3, X4, X5, Y1, Y2, Y3, Y4 can be pre-configured by the network side, or at least one of X1, X2, X3, X4, X5, Y1, Y2, Y3, Y4 can be indicated by the first information.

[0472] Among them, N1 to N 16 All are integers greater than or equal to zero.
[0473] Optional, N1 to N 16 At least one of them can be agreed upon by the agreement, or, N1 to N 16 At least one of them can be indicated by the first information, or, N1 to N 16 At least one of these can be pre-configured by the network side.
[0474] In some embodiments, the second target reference point is the latest reference point in the time domain among at least two preset reference points.
[0475] Optionally, the at least two reference points may include some or all of the second target reference points mentioned above.
[0476] In some embodiments, if the terminal performs the first operation in S220 above, the duration for the terminal to receive the second information or the SIB after the terminal sends the target uplink transmission is determined based on at least one of the following:
[0477] The first information, the third protocol agreement information, the feedback information of the target uplink transmission, and the target uplink transmission configuration corresponding to the target uplink transmission.
[0478] In this embodiment, the terminal can determine the duration for receiving the second information or SIB based on at least one of the first information, the third 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 it can receive the second information or SIB within the corresponding duration.
[0479] Optionally, the third protocol agreement information can directly determine the duration for which the terminal receives the second information or the SIB, or the third protocol agreement information can indirectly determine the duration for which the terminal receives the second information or the SIB.
[0480] Optionally, the feedback information of the target uplink transmission may directly or indirectly indicate the duration for which the terminal receives the second information or the SIB, and / or, the target uplink transmission configuration corresponding to the target uplink transmission may directly or indirectly indicate the duration for which the terminal receives the second information or the SIB.
[0481] In some embodiments, the wireless communication method 200 further includes:
[0482] The terminal receives feedback information transmitted uplink from the target.
[0483] The feedback information is used to indicate at least one of the following:
[0484] The sequence identifier corresponding to the target uplink transmission;
[0485] A positive response (ACK) or a negative response (NACK);
[0486] A specific downlink control channel, wherein the specific downlink control channel is used to schedule second information, or the specific downlink control channel is used to schedule SIB;
[0487] A specific search space, wherein the specific search space is used to search for second information, or the specific search space is used to search for SIBs;
[0488] The relevant information of the second information;
[0489] The identifier of at least one cell other than the target cell and the frequency point corresponding to the at least one cell;
[0490] The identifier of at least one carrier other than the carrier corresponding to the target cell and the frequency point corresponding to the at least one carrier;
[0491] The identifier of at least one TRP other than the TRP corresponding to the target cell and the frequency point corresponding to the at least one TRP.
[0492] In this embodiment, the terminal can perform subsequent operations based on the sequence identifier corresponding to the target uplink transmission.
[0493] In this embodiment, the terminal can determine whether the target uplink transmission was successful based on ACK or NACK.
[0494] In this embodiment, the terminal can schedule the second information based on a specific downlink control channel (such as a PDCCH scrambled with a specific RNTI), or the terminal can schedule the SIB (such as SIB1) based on a specific downlink control channel (such as a PDCCH scrambled with a specific RNTI).
[0495] In this embodiment, the terminal can search for the second information based on a specific search space (such as a specific search space configured in the MIB), or the terminal can search for the SIB (such as SIB1) based on a specific search space (such as a specific search space configured in the MIB).
[0496] In this embodiment, the terminal can receive the second information based on the relevant information of the second information.
[0497] In this embodiment, if the target cell prohibits terminal access, or if the terminal does not meet the access conditions of the target cell, the terminal may perform cell access based on the identifier of at least one cell other than the target cell and the frequency point corresponding to at least one cell; or, the terminal may perform cell access based on the identifier of at least one carrier other than the carrier corresponding to the target cell and the frequency point corresponding to at least one carrier; or, the terminal may perform cell access based on the identifier of at least one TRP other than the TRP corresponding to the target cell and the frequency point corresponding to at least one TRP.
[0498] In some embodiments, the terminal performs a first operation, including:
[0499] The terminal performs the first operation when the first condition is met;
[0500] The first condition includes, but is not limited to, at least one of the following:
[0501] The target cell meets the cell selection criteria;
[0502] The target cell did not prohibit the terminal from accessing;
[0503] The reference signal quality of the target cell is greater than or equal to the first threshold.
[0504] The terminal's measurement value for the first information is less than or equal to the second threshold;
[0505] The terminal's measurement value for the first information is greater than the third threshold, and the terminal's measurement value for the first information is less than or equal to the fourth threshold;
[0506] The number of repeated transmissions of the target uplink transmission is less than or equal to the fifth threshold.
[0507] The target cell only periodically sends the first information;
[0508] The first information does not include the second information;
[0509] The first information indicates the existence of the second information;
[0510] The target cell is not currently periodically sending SIBs;
[0511] The first information indicates that the terminal is allowed to request the second information as needed;
[0512] The detection energy of the first information is within the first energy range;
[0513] The terminal has services to be transmitted;
[0514] The terminal cannot detect any other suitable cells;
[0515] The terminal needs to access the target cell;
[0516] The terminal determines to reselect to the target cell.
[0517] In this embodiment, the terminal performs a first operation when a first condition is met. By constraining the terminal's execution of the first operation through the first condition, the rationality of the first operation performed by the terminal can be ensured.
[0518] 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.
[0519] For example, it is only meaningful 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 the first threshold. Otherwise, it may be faster to directly continue searching for SSB signals on other syncrasters.
[0520] For example, the detection energy of the first information can be divided into the following two cases:
[0521] 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).
[0522] Scenario 2: The second piece of information is triggered based on the target's uplink transmission;
[0523] 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.

[0537] The above text combined Figures 2 to 7 The terminal-side embodiments of this application are described in detail below, in conjunction with... 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.
[0538] Figure 8 This is a schematic flowchart of a wireless communication method 300 according to an embodiment of this application, such as... Figure 8 As shown, the wireless communication method 300 may include at least some of the following:
[0539] S310, the network-side device sends first information; 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;
[0540] S320, the network-side device performs a third operation;
[0541] The third operation includes one of the following:
[0542] Receive target uplink transmissions and send second information and SIB;
[0543] Receive target uplink transmissions and send SIBs;
[0544] Wherein, the second information is information that is not periodically sent by the target cell, or the second information is information that is not sent based on a request.
[0545] It should be understood that Figure 8 The steps or operations of the wireless communication method 300 are illustrated, but these steps or operations are merely examples, and other operations may be performed in this application. Figure 8 Variations of various operations within it.
[0546] In this embodiment of the application, the target cell can be a cell that transmits SIBs (SIB1) non-periodically, and the network-side equipment can be the base station (such as a gNB) of the target cell. For example, the target cell can be an energy-saving cell (NES cell).
[0547] In this embodiment, after the network-side device sends the first information, the terminal can determine whether the target cell is a cell that prohibits terminal access through the first information, blind detection, or protocol-defined information. Alternatively, the terminal can determine through the first information that the target cell allows the terminal to request the second information and SIB by sending the target uplink transmission. Or, the terminal can determine through the first information that the target cell allows the terminal to request the SIB by sending the target uplink transmission. Or, the terminal can determine through the first information that the target cell periodically sends the first information, the second information, and the SIB. Thus, the terminal can perform the first operation or the second operation accordingly. For the first operation, the terminal that initially searches can also access the target cell. For the second operation, the terminal that initially searches can avoid unnecessary reception of the second information, or the terminal that initially searches can avoid unnecessary reception of the second information and SIB, thereby reducing the power consumption of the terminal that initially searches. If the target cell is a cell that allows terminal access, or if the target cell allows the terminal to request the second information and SIB by sending a target uplink transmission, the terminal can send the target uplink transmission and receive the second information and SIB, thereby obtaining the second information and SIB in a timely manner; if the target cell is a cell that allows terminal access, or if the target cell allows the terminal to request the SIB by sending a target uplink transmission, the terminal can send the target uplink transmission and receive the SIB.

Optionally, if the first information includes part of the content 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 content of an SSB, and this application is not limited in this regard. Optionally, if the first information includes all of the content 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 content of an SSB, and this application is not limited in this regard.
[0549] 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.

[0713] The technical solution of this application is described in detail below through specific embodiments.
[0714] It should be noted that, in the following embodiments, the technical solution of this application is described in detail using the following example: the first information is a first-level SSB or a first part of an SSB, the second information is a second-level SSB or a second part of an SSB, the SIB is SIB1, the target uplink transmission is uplink WUS, and the target uplink transmission configuration is WUS configuration.
[0715] Example 1 details the technical solution of this application by taking the terminal receiving the first information from the target cell, sending the target uplink transmission, and receiving the second information and SIB (such as SIB1) as an example.
[0716] The target cell is a cell that sends SIBs (such as SIB1) non-periodically.
[0717] In this embodiment, the first information includes PSS, SSS, and PBCH payload. The PBCH payload contains the target uplink transmission configuration. The terminal obtains the target uplink transmission configuration based on the first information. If the first condition is met, the terminal sends the target uplink transmission based on the target uplink transmission configuration to request the target cell to send the second information and SIB. The terminal can determine the SIB reception configuration based on the second information. The terminal receives the SIB and determines whether it is allowed to camp on the target cell based on the SIB.
[0718] like Figure 9 As shown, the specific process of Embodiment 1 may include some or all of S1-1 to S1-4.

[0726] The beam identifier corresponding to SSB transmission (ssb-PositionInBurst);
[0727] RAR receiver configuration;
[0728] Subcarrier offset (Kssb) of SSB relative to CRB 0 or PRB 0;
[0729] Configuration information (pdcch-ConfigSIB1) used to schedule the PDCCH received by SIB1;
[0730] Full-duplex mode configuration;
[0731] Target uplink transmission configuration;
[0732] Relevant information for the second piece of information;
[0733] MIB Part 1;
[0734] It indicates the cell identifier and SSB frequency of the cell that is closest to the target cell and allows terminal access.
[0735] Optionally, the duplex mode configuration includes at least one of the following:
[0736] TDD or FDD;
[0737] TDD configuration (tdd-UL-DL-ConfigurationCommon);
[0738] Subband full duplex.
[0739] Optionally, TDD or FDD can be indicated by 1 bit. For example, a value of 0 indicates TDD and a value of 1 indicates FDD; or, a value of 1 indicates TDD and a value of 0 indicates FDD.
[0740] Optionally, if the duplex mode is configured as TDD, the transmission frequency of the target uplink transmission can be the center frequency of the SSS.
[0741] Optionally, if the duplex mode is configured as FDD, the transmission frequency of the target uplink transmission can be determined based on ARFCN, or the transmission frequency of the target uplink transmission can be determined based on the subcarrier offset (e.g., Kssb) of 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.

[0755] The transmission power of the second information;
[0756] The second information is configured for time and frequency resources;

[0758] 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.
[0759] For example, if the first information indicates that the second information does not exist, the UE believes that it can send a target uplink transmission to request the second information.
[0760] For example, the target uplink transmission can be understood as an uplink wake-up signal.
[0761] For example, the identifier that allows on-demand requests for the second information 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.
[0762] Optionally, the time-frequency resource configuration of the second information includes, but is not limited to, at least one of the following:

[0771] The frequency domain resource configuration information for the target uplink transmission;
[0772] The number of times the target uplink transmission is repeated;
[0773] Information related to the time window corresponding to the repeated resources in the target uplink transmission;

[0781] Optionally, the type of the target uplink transmission includes, but is not limited to, at least one of the following:
[0782] Random access related transmissions;
[0783] Upward reference signal (such as SRS);

[0834] 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.
[0835] 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.
[0836] Optionally, the unit for the transmission timing of the target uplink transmission includes, but is not limited to, one of the following:
[0837] Time slot, microtime slot, subframe, frame, symbol, millisecond, microsecond, second.
[0838] 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. For example, each first information transmitted periodically has an associated transmission timing of the target uplink transmission.
[0839] Optionally, the time-domain resource configuration information for 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. For example, the terminal can perform the target uplink transmission periodically.
[0840] 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.
[0841] 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.
[0842] Optionally, the frequency domain resource configuration information for the target uplink transmission includes at least one of the following:
[0843] ZeroCorrelationZoneConfig;
[0844] Frequency domain start position (e.g., msg1-FrequencyStart)
[0845] The number of transmission opportunities occupied by the frequency domain (e.g., msg1-FDM);
[0846] The number of SSBs associated with each transmission opportunity;
[0847] SCS during frequency domain transmission;
[0848] 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.
[0849] 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.
[0850] 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.
[0851] Optionally, MIB part 1 includes at least one of the following:
[0852] The community prohibits access to (cell bar) information;
[0853] System frame number;
[0854] Same frequency reselection information.
[0855] Optionally, the cell bar information includes, but is not limited to, at least one of the following:
[0856] Terminal features supported by the target cell;
[0857] The terminal feature combination supported by the target cell;
[0858] The types of terminals supported by the target cell.
[0859] Optionally, the target cell can be used to indicate whether to prohibit the terminal's access via cell bar information, or it can be used to indicate whether to allow access to the target cell. 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: RedCap, SDT, network slicing, XR, LPWA, eDRX, cell DRX or DTX, on-demand SIB1 (OD-SIB1), NES, etc.
[0860] Optionally, independent cell bar information can be introduced for different terminal types, different service types, and different coverage levels.
[0861] Optionally, the system frame number is used to determine the SSB burst when there is a subsequent uplink transmission of the target.
[0862] Optionally, the target cell can be instructed via intraFreqReselection whether to prohibit the terminal's access, or intraFreqReselection can be used to indicate whether access to the target cell is permitted.
[0863] Optionally, the cell closest to the target cell that the terminal is allowed to access, indicated by the first 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.
[0864] S1-2. The terminal (such as the terminal in the initial search) performs the first operation if the first condition is met;
[0865] The first operation includes one of the following:
[0866] Sending target uplink transmissions and receiving second information and SIBs;
[0867] Sending target uplink transmissions and receiving SIBs;
[0868] The first condition includes, but is not limited to, at least one of the following:
[0869] The target cell meets the cell selection criteria;
[0870] The target cell did not prohibit the terminal from accessing;
[0871] The reference signal quality of the target cell is greater than or equal to the first threshold.
[0872] The terminal's measurement value for the first information is less than or equal to the second threshold;
[0873] The terminal's measurement value for the first information is greater than the third threshold, and the terminal's measurement value for the first information is less than or equal to the fourth threshold;
[0874] The number of repeated transmissions of the target uplink transmission is less than or equal to the fifth threshold.
[0875] The target cell only periodically sends the first information;
[0876] The first information does not include the second information;
[0877] The first information indicates the existence of the second information;
[0878] The target cell is not currently periodically sending SIBs;
[0879] The first information indicates that the terminal is allowed to request the second information as needed;
[0880] The detection energy of the first information is within the first energy range;
[0881] The terminal cannot detect any other suitable cells;
[0882] The terminal has services to be transmitted;
[0883] The terminal needs to access the target cell;
[0884] The terminal determines to reselect to the target cell.
[0885] In this embodiment, the terminal performs a first operation when a first condition is met. By constraining the terminal's execution of the first operation through the first condition, the rationality of the first operation performed by the terminal can be ensured.
[0886] 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.
[0887] For example, it is only meaningful 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 the first threshold. Otherwise, it may be faster to directly continue searching for SSB signals on other syncrasters.
[0888] For example, the detection energy of the first information can be divided into the following two cases:
[0889] 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).
[0890] Scenario 2: The second piece of information is triggered based on the target's uplink transmission;
[0891] In case 1, the first information specifies 20 PRBs; in case 2, the first information specifies 12 PRBs. As shown in Table 1 above, if the SSB's SCS is 15kHz and the terminal detects that the energy occupancy of the first information is 300kHz, 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, and under the condition that the first condition is met, the terminal can perform the target uplink transmission.
[0892] S1-3. The terminal receives the second information.
[0893] Optionally, the second information includes at least one of the following:
[0894] SIB receive configuration (e.g., pdcch-ConfigSIB1);
[0895] The location of the DMRS for type A;
[0896] Uplink common subcarrier spacing (SubCarrierSpacingCommon);
[0897] SSB is the subcarrier offset relative to CRB 0 or PRB 0 (e.g., Kssb).
[0898] Optionally, the SIB receive configuration can occupy 8 bits, the DMRS position of type A can occupy 1 bit, the uplink common subcarrier spacing can occupy 1 bit, and the SSB subcarrier offset (such as Kssb) relative to CRB 0 or PRB 0 can occupy 4 bits.
[0899] Optionally, the time-frequency resource configuration of the second information is determined based on at least one of the following:
[0900] The first information, the second association, the identifier of the target cell, the PCI value of the target cell, and the second protocol agreement information;
[0901] The second association relationship includes, but is not limited to, at least one of the following:
[0902] The relationship between terminal type and time-frequency resource configuration of the second information, the relationship between terminal characteristics and time-frequency resource configuration of the second information, the relationship between terminal function and time-frequency resource configuration of the second information, and the relationship between time-frequency resource configuration of the first information and time-frequency resource configuration of the second information.
[0903] In this embodiment, the terminal can determine the time-frequency resource configuration of the second information based on the first information, the second association relationship, the identifier of the target cell, the PCI value of the target cell, and the second protocol agreement information, thereby enabling it to receive the second information.
[0904] For example, the first information may directly indicate at least one of the following: the sync raster identifier corresponding to the second information, the band identifier corresponding to the second information, the TRP identifier corresponding to the second information, and the carrier identifier corresponding to the second information.
[0905] For example, the second information and the first information may or may not be on the same sync raster. For instance, the sync raster where the second information is located can be determined based on the sync raster where the first information is located.
[0906] For example, the terminal type is associated with the time-frequency resource configuration of the second information, and the terminal can determine the time-frequency resource configuration of the second information based on its terminal type. For instance, an LPWA UE only transmits the target uplink transmission on frequency band 1 and receives the second information only on synchronization grid 1; an emBB UE only transmits the target uplink transmission on frequency band 2 and receives the second information only on synchronization grid 2; wherein, synchronization grid 1 can be sparser than synchronization grid 2, which is beneficial for the initial search of the LPWA UE.
[0907] For example, the terminal may obtain the identifier of the target cell based on the first information, and the terminal may determine the offset between the time-frequency resource location of the second information and the time-frequency resource location of the first information based on the identifier of the target cell.
[0908] For example, the terminal can obtain the PCI value of the target cell based on the first information, and the terminal can determine the offset between the time-frequency resource location of the second information and the time-frequency resource location of the first information based on the PCI value of the target cell.
[0909] For example, the terminal can determine the offset between the time-frequency resource location of the second information and the time-frequency resource location of the first information based on the PSS sequence or SSS sequence in the first information.
[0910] Optionally, the second protocol-defined information can directly determine the time-frequency resource configuration of the second information, or the second protocol-defined information can indirectly determine the time-frequency resource configuration of the second information.
[0911] It should be noted that the content of the first and second information does not overlap. For example, if kssb is indicated in the first information, then kssb is not included in the second information.
[0912] S1-4. The terminal receives SIB (e.g., SIB1).
[0913] The SIB (e.g., SIB1) can be an on-demand SIB1.
[0914] In Example 1, when the initial search terminal finds the target cell, if the target cell is in power-saving mode (not sending SIB1), the terminal can send a target uplink transmission request (SIB1) to further determine whether to allow camping in the target cell. Compared to related technologies, the terminal does not need to first camp in a non-power-saving cell (such as cell A) to obtain a valid WUS configuration. In this example, the initial search terminal is allowed to directly wake up the target cell.
[0915] Example 2 details the technical solution of this application by taking as an example how the terminal identifies the searched cell as the target cell, or how it determines whether it is a cell that allows the transmission of the target uplink to request the SIB (such as SIB1) to send.
[0916] For the target cell, there are four possible states:
[0917] Network State 1: The content of the second information can be included in the first information, that is, only the first information is sent. The SIB (such as SIB1) does not send periodically, and the terminal is allowed to send the target uplink transmission to request the SIB (such as SIB1) to send it; such as the target cell only periodically sends the first information (which includes the second information).
[0918] Network State 2: The content of the second information is not included in the first information, allowing the terminal to send the target uplink transmission to request the transmission of the second information + SIB (such as SIB1);
[0919] Network State 3: No terminal is required to send target uplink transmissions to request the transmission of second information and SIB (such as SIB1); for example, when the target cell periodically sends first information and second information and SIB (such as SIB1);
[0920] Network State 4: Terminals are not allowed to trigger wake-up of the cell; for example, in this case, the first information does not contain the target uplink transmission configuration, nor does it contain the relevant information of the second information. The terminal cannot send the target uplink transmission to wake up the cell, and the cell can be woken up by other base stations.
[0921] Optionally, the transmission block size (TBS) of the first information may vary under different network conditions, as shown in Table 2 below.
[0922] Table 2
[0923]
[0924] In this embodiment, the terminal can determine the network status of the target cell based on some indications of the target cell or by blind search.
[0925] Optionally, the terminal determines the network status of the target cell based on at least one of the following:
[0926] Whether the terminal blindly detects the second information or SIB (such as SIB1);
[0927] Whether the terminal blindly detects feedback information of the target uplink transmission sent by other terminals;
[0928] The energy level of the first piece of information detected by the terminal;
[0929] The frequency domain range corresponding to the first piece of information;
[0930] The GSCN value range corresponding to the first piece of information;
[0931] Is the first piece of information located in the synchronization grid?
[0932] SSB's SCS;
[0933] The reference signal indication in the first information;
[0934] PCI indication in the first message;
[0935] The relationship between the first piece of information and the network state, or the relationship between the values of some information elements in the first piece of information and the network state.
[0936] In this embodiment, the terminal determines the network state of the target cell based on whether the second information is blindly detected. For example, if the terminal blindly detects the second information, the terminal does not need to perform target uplink transmission, but directly receives the second information and / or SIB (such as SIB1), and the target cell is in network state 1 or network state 3.
[0937] In this embodiment, the terminal determines the network state of the target cell based on the energy level of the detected first information. For example, if the energy level of the first information detected by the terminal does not exceed a specific value, the target cell is in network state 2 or network state 4; if the energy level of the first information detected by the terminal exceeds the specific value, the target cell is in network state 1 or network state 3. As another example, if the first information does not contain the second information, the energy level of the first information detected by the terminal is 3.6 joules; if the first information contains the second information, the energy level of the first information detected by the terminal is 4.8 joules. If the second information or SIB has already started transmitting, the terminal does not need to perform target uplink transmission.
[0938] In this embodiment, the terminal determines the network state of the target cell based on the frequency domain range corresponding to the first information. Optionally, the frequency domain range corresponding to the first information is associated with the network state; wherein, if the frequency domain range corresponding to the first information is associated with network state 2 or network state 4, the second information or SIB has not started to be transmitted; if the frequency domain range corresponding to the first information is associated with network state 1 or network state 3, the second information or SIB has started to be transmitted.
[0939] In this embodiment, the terminal determines the network state of the target cell based on the GSCN value range corresponding to the first information. Optionally, the GSCN value range corresponding to the first information is associated with the network state; wherein, if the GSCN value range corresponding to the first information is associated with network state 2 or network state 4, the second information or SIB has not started to be sent; if the GSCN value range corresponding to the first information is associated with network state 1 or network state 3, the second information or SIB has started to be sent.
[0940] In this embodiment, the terminal determines the network state of the target cell based on whether the first information is located in a synchronization raster. Optionally, whether the first information is located in a synchronization raster is associated with the network state; wherein, if the first information is located in network state 2 associated with a synchronization raster, the second information or SIB has not started to be transmitted; if the first information is located in network state 3 associated with an off-sync raster, the second information or SIB has started to be transmitted, such as if the first information already contains the second information and / or SIB.
[0941] In this embodiment, the terminal determines the network state of the target cell based on the subcarrier spacing of the SSB. Optionally, if the SSB's SCS is the first SCS, the terminal is allowed to send a target uplink transmission request to wake up the target cell, and the target cell is in network state 2, and the second information or SIB has not yet started transmission; if the SSB's SCS is the second SCS, the target cell is in network state 1 or network state 3, and the second information or SIB has already started transmission. For example, the first subcarrier spacing is 30kHz, and the second subcarrier spacing is 15kHz.
[0942] In this embodiment, the terminal can determine whether the second information or SIB has started to be transmitted based on whether feedback information corresponding to the target uplink transmission triggered by other terminals is blindly detected. For example, the feedback of all target uplink transmissions is scrambled by a common RNTI. Before transmitting the target uplink transmission, the terminal first searches for the feedback of the target uplink transmission in a specific search space (SS) (such as a common search space configured on the network side). If the RAR corresponding to the target uplink transmission sent by other terminals can be found in the specific SS, the terminal considers that the second information and SIB (such as SIB 1) have been triggered by other terminals, and there is no need to transmit the target uplink transmission again.
[0943] Optionally, the association between the operating band and the SSB's SCS can be agreed upon by the protocol.
[0944] Optionally, the reference signal in the first information may indicate the network status of the target cell.
[0945] For example, the PBCH load in the first information indicates the network status of the target cell.
[0946] For example, the subcarrier offset (kssb) of the SSB relative to CRB 0 or PRB 0 in the first information indicates the network status of the target cell. For instance, the meaning of different kssb value ranges can be redefined. The meaning of different kssb value ranges for FR1 is shown in Table 3 below, and the meaning of different kssb value ranges for FR2 is shown in Table 4 below.
[0947] Table 3
[0948]
[0949] Table 4
[0950]
[0951]
[0952] The division of different KSB intervals in Tables 3 and 4 is only an example. In actual applications, the division points of different KSB intervals may differ from those in the examples.
[0953] Optionally, the physical layer of the PBCH in the first information indicates the network status of the target cell.
[0954] For example, if the SCS of CRB and SSB are always the same (there is only one SCS for a carrier), then kssb only needs 4 bits. Then the bit in PBCH that was originally used for FR1 Kssb can be used to indicate the network status of the target cell.
[0955] Optionally, the reference signal in the first information indicates the network status of the target cell.
[0956] For example, the network status associated with DMRS in the first information indicates the network status of the target cell.
[0957] For example, the network status associated with the PSS in the first piece of information indicates the network status of the target cell. There are three possibilities for the PSS.
[0958] For example, the network status associated with the SSS in the first piece of information indicates the network status of the target cell. There are 336 possible SSS values.
[0959] For example, the network status associated with the relative positions of DMRS and PSS in the first information indicates the network status of the target cell.
[0960] For example, the network status associated with the relative positions of SSS and PSS in the first information indicates the network status of the target cell.
[0961] Optionally, the PCI in the first information indicates the network status of the target cell.
[0962] For example, the network status associated with the PCI in the first piece of information indicates the network status of the target cell.
[0963] In Example 2, the initial search terminal can distinguish whether the searched cell is a completely blocked cell or a cell that allows the terminal to send on-demand requests for SIBs (such as SIB1) through the target uplink transmission, thereby allowing the initial search terminal to access the target cell.
[0964] Example 3 details the technical solution of this application by taking the terminal obtaining the target uplink transmission configuration as an example.
[0965] The terminal obtains the target uplink transmission configuration based on at least one of the following:
[0966] First information, first relationship, first agreement information;
[0967] 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;
[0968] The first association relationship includes the association relationship between the characteristics of the target cell and the target uplink transmission configuration;
[0969] 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 the downlink reference point A (DL point A) (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).
[0970] 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 obtain the second information and SIB, and can also access the target cell.
[0971] 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 its identifier. 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 its identifier. 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 its identifier.
[0972] Optionally, the protocol predefines the available time-frequency resources for the target uplink transmission. For example, in the time domain, `periodicityAndOffset` is configured according to a period plus offset. The transmission timing for each target uplink transmission includes at least one of the following: the number of symbols, the number of consecutive transmission timings in the time domain, the number of transmission timings in the frequency domain, and the frequency domain start position. Alternatively, for example, the resources for the target uplink transmission are related to the location of the SSB, and the time-frequency resources for the target uplink transmission have a fixed offset from each SSB burst / specified SSB burst. Here, the time domain offset can be a symbol-level / slot-level offset relative to the SSB burst, and the frequency domain offset can be relative to the SSB. The frequency domain offset can also be an RB-level offset relative to UL point A, and the number of frequency domain RBs can be predefined.
[0973] Optionally, Type 0PDCCH can be jointly encoded with the target uplink transport configuration.
[0974] Optionally, the frequency domain position of the target uplink transmission can be offset by a fixed length relative to the uplink reference point A (UL point A) or the downlink reference point A (DL point A) (such as an offset at the resource block (RB) granularity or a subcarrier granularity). This can also be pre-configured by the network side or agreed upon by the protocol, and this application does not limit this.
[0975] For example, the at least one bit in the first information can be an added bit or a reserved bit. For instance, the at least one bit can be an added bit or a reserved bit in the MIB.
[0976] 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.
[0977] For example, if the SSB of the target cell is on an off-sync raster, the individual IEs in the MIB of the SSB can be redefined to explicitly or implicitly indicate the corresponding target uplink transport configuration or the identifier of the target uplink transport configuration.
[0978] For example, the protocol stipulates that the time-frequency location of the target uplink transmission is associated with the first information.
[0979] 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.
[0980] 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.
[0981] Optionally, the characteristics of the target cell include, but are not limited to, at least one of the following:
[0982] 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.
[0983] For example, the protocol predefines multiple sets of target uplink transmission configurations, with the first information of the target cell indicating the identifier of the target uplink transmission configuration to be used.
[0984] Each target uplink transmission configuration is associated with a different sync raster, or with a different GSCN value, GSCN value range, frequency range, or operating band, or with a different SSB period or SSB subcarrier spacing.
[0985] 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.
[0986] 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.
[0987] 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.
[0988] 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.
[0989] 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.
[0990] 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.
[0991] 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.
[0992] 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.
[0993] 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.
[0994] For example, the PCI value (PSS+SSS) 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.
[0995] 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.
[0996] Example 4 details the technical solution of this application by taking the terminal obtaining feedback information of the target uplink transmission as an example.
[0997] The feedback configuration for the target uplink transmission can be indicated by the first information, or the feedback configuration for the target uplink transmission can be agreed upon by the protocol.
[0998] Specifically, the terminal receives feedback information transmitted uplink from the target.
[0999] The feedback information is used to indicate at least one of the following:

[1004] Relevant information for the second piece of information;
[1005] The identifier of at least one cell other than the target cell and the frequency point corresponding to the at least one cell;

[1007] The identifier of at least one TRP other than the TRP corresponding to the target cell and the frequency point corresponding to the at least one TRP.
[1008] Optionally, the at least one cell may include a non-target cell or some NES cells that have already been woken up.
[1009] In this embodiment, the terminal can perform subsequent operations based on the sequence identifier corresponding to the target uplink transmission.
[1010] In this embodiment, the terminal can determine whether the target uplink transmission was successful based on ACK or NACK.
[1011] In this embodiment, the terminal can schedule the second information based on a specific downlink control channel (such as a PDCCH scrambled with a specific RNTI), or the terminal can schedule the SIB (such as SIB1) based on a specific downlink control channel (such as a PDCCH scrambled with a specific RNTI).
[1012] In this embodiment, the terminal can search for the second information based on a specific search space (such as a specific search space configured in the MIB), or the terminal can search for the SIB (such as SIB1) based on a specific search space (such as a specific search space configured in the MIB).
[1013] Optionally, the relevant information of the second information includes, but is not limited to, at least one of the following:
[1014] Does the second information exist?
[1015] Whether to allow the terminal to request the second information on demand;
[1016] The identifier that allows on-demand requests for the second information;
[1017] The relationship between the second information and the first information;
[1018] The beam identifier of the second information;
[1019] The type of the second information;
[1020] The duration of the time window used to monitor the second information;
[1021] The duration of sending the second message;
[1022] The actual sending location of the second message (ssb-PositionInburst);
[1023] The subcarrier spacing of the second information;
[1024] The sending period of the second information;

[1026] The transmission power of the second information;
[1027] The second information is configured for time and frequency resources;
[1028] The relative position information of the second information.
[1029] In this embodiment, the terminal can receive the second information based on the relevant information of the second information.
[1030] In this embodiment, if the target cell prohibits terminal access, or if the terminal does not meet the access conditions of the target cell, the terminal may perform cell access based on the identifier of at least one cell other than the target cell and the frequency point corresponding to at least one cell; or, the terminal may perform cell access based on the identifier of at least one carrier other than the carrier corresponding to the target cell and the frequency point corresponding to at least one carrier; or, the terminal may perform cell access based on the identifier of at least one TRP other than the TRP corresponding to the target cell and the frequency point corresponding to at least one TRP.
[1031] Example 5 details the technical solution of this application using the target uplink transmission configuration as an example.
[1032] All parameters required for the target uplink transmission are configured in a table. Different target uplink transmission configuration indexes correspond to different target uplink transmission configurations. Each row in the table represents a predefined target uplink transmission configuration, and each row contains some or all of the parameters shown in Table 5 below. For example, an optional implementation of the target uplink transmission can be shown in Table 6.

[1037]
[1038] Example 6 details the technical solution of this application by taking the example that the time-frequency position of the target uplink transmission has a fixed offset relative to the time-frequency position of the first information.
[1039] In some implementations, the time-domain position of the target uplink transmission has a fixed offset relative to the time-domain position of the first information, such as... Figure 10 As shown, the time domain position of the target uplink transmission is offset by 1 relative to the time domain position of the first information. The offset 1 can be indicated by the first information, or the offset 1 can be agreed upon by the protocol.
[1040] In some implementations, the center frequency of the target uplink transmission is the same as the center frequency of the first information, with no offset in the frequency domain, such as... Figure 11 As shown.
[1041] In some implementations, the frequency domain position of the target uplink transmission has a fixed offset relative to the frequency domain position of the first information, such as... Figure 12As shown, the center frequency position of the target uplink transmission is offset by 2 relative to the center frequency position of the first information. The offset 2 can be indicated by the first information, or the offset 2 can be agreed upon by the protocol.
[1042] Optionally, offset 2 can be an offset at the RB granularity, or offset 2 can be an offset at the subcarrier granularity, or offset 2 is the difference between the transmission timing of the target uplink transmission and the GSCN value of the first information, or offset 2 is the difference between the transmission timing of the target uplink transmission and the ARFCN value of the first information.
[1043] Example 7 details the technical solution of this application by taking the terminal's execution of sending the second information of the target uplink transmission request and the SIB (such as SIB1) as an example.
[1044] In some implementations, such as Figure 13 As shown, the first information and the second information are two independent parts.
[1045] 1) The target cell periodically sends the first information with a period of T1, which includes PSS+SSS+PBCH (containing the target uplink transmission configuration and a part of the MIB);
[1046] Furthermore, the time-domain candidate position of the target uplink transmission is a fixed offset of offset1 relative to the first information, and the frequency-domain candidate position is consistent with the first information (if inconsistent, it can be indicated in the first information or predefined by the protocol).
[1047] Furthermore, the temporal candidate position of the second information is a fixed offset of offset2 relative to the first information, and the frequency domain candidate position is consistent with the first information (if inconsistent, it can be indicated in the first information or predefined by the protocol);
[1048] 2) When the initial search terminal finds the target cell, it detects PSS+SSS and meets the S criterion for cell camping. At the transmission time of the target uplink transmission, it sends the target uplink transmission to request the transmission of the second information and SIB (such as SIB1).
[1049] 3) When the network-side device receives the target uplink transmission, the terminal starts receiving the second information from the candidate position of the next second information in the target uplink transmission;
[1050] 4) The terminal receives SIB1 based on the SIB1 configuration (pdcch-ConfigSIB1) decoded from the second information, and determines whether to allow camping in the target cell based on the information in SIB1. If the camping conditions are met, the terminal camps in the target cell.
[1051] Example 8 details the technical solution of this application by taking the sending of the target uplink transmission request SIB1 by the terminal as an example.
[1052] In some implementations, such as Figure 14 As shown, the first information includes the second information.
[1053] 1) The target cell periodically sends the first information with a period of T1, which includes PSS+SSS+PBCH (containing the target uplink transmission configuration and the entire MIB);
[1054] Furthermore, the time-domain candidate position of the target uplink transmission is a fixed offset of offset1 relative to the first information, and the frequency-domain candidate position is consistent with the first information (if inconsistent, it can be indicated in the first information or predefined by the protocol).
[1055] 2) When the initial search terminal finds the target cell, it detects PSS+SSS and finds that it meets the S criterion for cell camping. At the transmission time of the target uplink transmission, it performs the target uplink transmission to request the transmission of SIB1.
[1056] 3) When the network-side device receives the target uplink transmission, the terminal starts receiving SIB1 scheduling information at the transmission time of the next type 0PDCCH of the target uplink transmission.
[1057] 4) The terminal receives SIB1 and determines whether it is allowed to camp on the target cell based on the information in SIB1. If the camping conditions are met, the terminal camps on the target cell.
