[0038] This disclosure provides a method, terminal, device, system, and storage medium for sending and receiving configuration information.

[0039] In a first aspect, embodiments of this disclosure provide a method for receiving configuration information, executed by a terminal, the method comprising:

[0040] The network device receives configuration information, wherein the configuration information is used to configure a first parameter associated with at least one Synchronization Signal Block (SSB), the first parameter is used to indicate a correspondence, the correspondence being the relationship between the first SSB associated with the first parameter and the number of Random Access Channel (RO) associated with the first SSB, and the first SSB being a subset of the at least one SSB.

[0041] In the above embodiments, based on the configuration information of network devices, the first parameter associated with one or more SSBs is configured to indicate the number of ROs associated with the SSB with a smaller configuration granularity. This allows the configuration of ROs to be reasonably adjusted in combination with the actual user distribution under different SSBs, improving configuration flexibility and making it easier to meet high access requirements or efficiently utilize RO resources.

[0042] In conjunction with the embodiments of the first aspect, in some embodiments, the configuration information includes at least one first parameter, wherein each first parameter is associated with one of at least one SSB.

[0043] In the above embodiments, a separate first parameter is configured for each SSB at the per SSB granularity, so that for SSBs with different user distributions, a reasonable number of ROs can be configured based on the actual user distribution of each SSB.

[0044] In conjunction with the embodiments of the first aspect, in some embodiments, the method further includes:

[0045] The RO of each SSB mapping is determined based on the index order of at least one SSB and at least one first parameter.

[0048] The number of ROs associated with each SSB is determined based on the first parameter associated with each SSB.

[0049] Based on the SSB index order from smallest to largest and the number of ROs associated with each SSB, among the multiple ROs corresponding to the first time domain unit, the ROs mapped by the SSB with the smaller SSB index and the ROs mapped by the SSB with the larger SSB index are determined sequentially.

[0050] In conjunction with the embodiments of the first aspect, in some embodiments, determining the RO of each SSB mapping based on the index order of the at least one SSB and the at least one first parameter includes:

[0051] Based on the first parameter associated with the first SSB and the second SSB in the at least one SSB, determine the number of ROs associated with the first SSB and the number of ROs associated with the second SSB.

[0052] Among the multiple ROs corresponding to the first time domain unit, the RO mapped by the first SSB and the RO mapped by the second SSB are determined sequentially, wherein the index of the first SSB is less than the index of the second SSB.

[0053] In conjunction with the embodiments of the first aspect, in some embodiments, determining the RO of each SSB mapping based on the index order of the at least one SSB and the at least one first parameter further includes:

[0054] If the multiple ROs corresponding to the first time domain unit are only associated with some of the at least one SSB, then among the ROs corresponding to the time domain units after the first time domain unit, determine the ROs associated with the remaining SSBs in the at least one SSB.

[0055] In the above embodiments, during the mapping process of SSB and RO, based on the SSB index, different ROs of the same time domain unit can be mapped first, and then ROs of other time domain units can be mapped.

In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0155] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0160] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication processing methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0161] In some implementations, 5G can meet users' demands for speed, latency, high-speed mobility, energy efficiency, and the diverse and complex communication needs of future services. The main application scenarios of 5G include Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low Latency Communications (URLLC), and Massive Machine-Type Communication (mMTC). eMBB, targeting users' access to multimedia content, services, and data, is experiencing rapid demand growth. eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, with significant differences in capabilities and requirements, requiring detailed analysis based on specific deployment scenarios. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety assurance. Typical characteristics of mMTC include high connection density, small data volume, latency-insensitive services, low module cost, and long module lifespan.

[0162] In some implementations, uplink power is limited for terminals in NR, and the higher frequency of the NR spectrum results in greater propagation loss, thus limiting uplink coverage. To improve uplink coverage in the high-frequency bands of NR, supplementary uplink (SUL) frequencies can be introduced into a cell in addition to the normal uplink (NUL). These SUL frequencies can be low-frequency, such as LTE spectrum, utilizing the low frequency for uplink to enhance coverage.

[0163] In scenarios where SUL is introduced, the two UL carriers (NUL and SUL) and the DL carrier belong to the same cell. At most, only one Physical Uplink Shared Channel (PUSCH) can be used for transmission at any given time. The terminal can determine the UL to use based on network-side instructions, or the terminal can decide the UL selection based on a measurement threshold, which can be configured via system broadcast. The two UL carriers can be dynamically switched based on Downlink Control Information (DCI) instructions.

[0164] Each of the NUL and SUL has its own independent Random Access Channel (RACH) resource configuration, which includes, for example, an independent per-carrier preamble configuration, an independent per-carrier RO resource configuration, and an independent RACH control parameter configuration.

[0165] In some implementations, as shown in Figure 1b, the two-step random access process may include the following steps:

[0166] S1100, network devices can assign random access preambles (RA preamble assignment) to terminals;

[0167] S1101, The terminal can send MSG1 to the network device;

[0168] S1102. The network device can send MSG2 to the terminal.

[0169] As shown in Figure 1c, the four-step random access process may include the following steps:

[0170] S1201, The terminal can send MSG1 to the network device;

[0171] S1202, The network device sends MSG2 to the terminal;

[0172] S1203, The terminal sends MSG3 to the network device;

[0173] S1204, The network device sends MSG4 to the terminal;

[0174] The transmission of the above message is completed within a single cell.

[0175] MSG1 carries the Random Access Preamble, MSG2 carries the Random Access Response (RAR), MSG3 is the Scheduled Transmission, and MSG4 is used for Contention Resolution.

[0176] Taking a 4-step random access method as an example, the terminal can perform corresponding operations during the random access process. For example:

[0177] In the first step:

[0178] The terminal determines the relationship between SSB and RACH resources and / or preamble based on the high-level configuration.

[0179] The terminal receives a set of SSBs and determines their Reference Signal Receiving Power (RSRP) value, and selects an appropriate SSB based on the RSRP threshold; based on the selected SSB and the correspondence between the SSB and RACH resources, the terminal determines the range of RACH resources and Preamble resources.

[0180] The terminal selects a preamble group based on the size of MSG3, and then randomly selects a preamble within that group. The target receive power is set, for example, based on the following configured or defined parameters: preambleReceivedTargetPower + DELTA_PREAMBLE + (PREAMBLE_POWER_RAMPING_COUNTER – 1) × powerRampingStep, where preambleReceivedTargetPower is the preamble target receive power, PREAMBLE_POWER_RAMPING_COUNTER is the power ramp count, and powerRampingStep is the power ramp step size.

[0181] The terminal transmits the preamble sequence on the time-frequency domain resources of the Physical Random Access Channel (PRACH).

[0182] In the second step:

[0183] The terminal determines the Radio Network Temporary Identifier (RA-RNTI) based on the time-frequency domain resources of the PRACH sent to MSG1. For example, RA-RNTI = 1 + s_id + 14 × t_id + 14 × 80 × f_id + 14 × 80 × 8 × ul_carrier_id, where s_id represents the Orthogonal Frequency Division Multiplexing (OFDM) symbol index, t_id represents the time slot index, f_id represents the frequency domain index, and ul_carrier_id represents the uplink carrier identifier.

[0184] The terminal opens the RAR time window (ra-Response Window) at the first Physical Downlink Control Channel (PDCCH) occasion after sending the preamble, and listens for the RA-RNTI scrambled PDCCH during the operation of the time window in order to receive the corresponding RA-RNTI RAR.

[0185] If the terminal does not receive a RAR within the RAR monitoring window, or does not receive the RAR corresponding to the transmit Preamble identifier (RAPID), the terminal can perform a power ramp and execute MSG1 retransmission. Whether the terminal ramps depends on whether it switches beams.

[0186] If a RAR is received within the RAR monitoring window, and if it is the first RAR received, the Media Access Control (MAC) Protocol Data Unit (PDU) is obtained from the multiplexing and assembly entity and stored in the MSG3 buffer.

[0187] In the third step:

[0188] If the terminal does not have its own cell RNTI (C-RNTI), the execution of this RACH is triggered by the Common Control Channel (CCCH). In this case, MSG3 is a MAC PDU generated with the CCCH Service Data Unit (SDU) as input. If the terminal has its own C-RNTI, the terminal indicates that the multiplexing and assembly entity includes the C-RNTI MAC CE. In this case, MSG3 is a MAC PDU generated by the C-RNTI MAC CE.

[0189] The terminal obtains the MAC PDU from the MSG3 buffer and transmits the MAC PDU based on the UL grant in the RAR.

[0190] After MSG3 is transmitted, a conflict timer (ra-ContentionResolutionTimer) is started. During the execution of this timer, the terminal listens to the PDCCH. If MSG3 contains a C-RNTI MAC CE, the terminal listens to the PDCCH scrambled with that C-RNTI. If MSG3 does not contain a C-RNTI MAC CE, the terminal listens to a temporary C-RNTI and receives MSG4.

[0191] When MSG3 performs a Hybrid Automatic Repeat reQuest (HARQ) retransmission, the conflict timer is restarted; the terminal will continue to listen to PDCCH until the timer expires or stops; MSG3 HARQ retransmission is scrambled and scheduled based on temporary C-RNTI.

[0192] In the fourth step:

[0193] If MSG3 contains C-RNTI MAC CE, the terminal listens for the PDCCH scrambled by that C-RNTI. If it detects the PDCCH, the conflict is considered resolved successfully. If it does not detect the PDCCH, the conflict is considered resolved unsuccessfully.

[0194] If MSG 3 does not contain C-RNTI MAC CE, the terminal listens for the temporary C-RNTI and receives MSG4. If MSG4 is received and matches the CCCH SDU, the conflict resolution is successful; otherwise, the conflict resolution fails.

[0195] If conflict resolution fails, the terminal can increase its power and retransmit MSG1. Whether the terminal increases its power depends on whether it switches beams.

[0196] In some implementations, in scenarios where DL public information is transmitted using beam sweeping, the terminal can determine the beam or beam direction with better reception quality based on measurements, and receive downlink information under that beam. When the terminal randomly accesses the network side, it needs to report the selected beam to the network side so that the network side can send UE-specific data to the terminal under that beam. To notify the network side that RO resources and / or preambles are associated with SSBs during random access, the terminal can indicate or indicate the selected RO resources and / or preamble by sending MSG1 after selecting a beam; the network device determines the SSB associated with the RO resources and / or preamble based on the received MSG1, thereby determining the beam selected by the terminal (which can be represented by an SSB index).

[0197] The association between SSBs and ROs can be configured via the parameter SSB-per-RO. In some implementations, the configuration of the association between SSBs and ROs is configured on a per-cell basis, with different SSBs having the same number of associated ROs. For example, referring to Figure 1d, the number of SSBs is 8, denoted as SSB1 to SSB8. Configuring prach_FDM=4 means there are 4 ROs on each time-domain unit. As shown in Figure 1d, if SSB_per_RO=1 / 4 is configured, meaning 1 SSB is associated with 4 ROs, then for the 8 SSBs from SSB1 to SSB8, each SSB corresponds to 4 ROs. If SSB_per_RO=2 is configured, meaning 2 SSBs are associated with 1 RO, then for the 8 SSBs from SSB1 to SSB8, every two SSBs correspond to 1 RO.

[0198] In actual network deployments, as shown in Figure 1e, the terminals covered by each SSB are not uniformly distributed; the distribution of terminals varies in different directions or areas. For example, in the Internet of Things (IoT), the density of IoT devices varies in different areas; the distribution of devices in areas with dense IoT devices facing factories differs from that in open factory areas. If the per-cell configuration method is used to configure the association between SSB and RO, the following problems will occur:

[0199] To accommodate the massive influx of IoT devices into the network, it's necessary to allocate more Returning Objects (ROs) to a single Service Block (SSB), meaning an SSB needs to be associated with more ROs to meet the access capacity of a large number of IoT devices. For example, as shown in Figure 1d, configuring SSB_per_RO = 1 / 4 means each SSB in the cell corresponds to 4 ROs. In this case, for areas with fewer IoT devices, such as the SSB1 direction in Figure 1e, the coverage area is smaller, and having too many associated ROs would waste RO resources. Conversely, if the SSB is associated with fewer ROs, then for SSB directions with more devices, the RO resources are limited and cannot accommodate enough devices accessing the network.

[0200] This disclosure provides a method for sending and receiving configuration information to reasonably configure the relationship between random access information and beams, such as the relationship between SSB and RO.

[0201] Figure 2a is an interactive schematic diagram illustrating a method for sending and receiving configuration information according to an embodiment of the present disclosure. As shown in Figure 2a, this embodiment of the present disclosure relates to a method for sending and receiving configuration information, the method including:

[0202] In step S2101, network device 102 sends configuration information to terminal 101.

[0203] In some embodiments, terminal 101 may include user equipment, Internet of Things (IoT) devices, or environmental IoT devices, etc.

[0204] In some embodiments, the configuration information may also be instruction information or auxiliary information, etc., and the name is for illustrative purposes only and not a limitation.

[0205] In some embodiments, configuration information can be sent via broadcast system information.

[0206] In some embodiments, the configuration information is used to configure a first parameter associated with at least one synchronization signal block (SSB). Here, at least one SSB may be one or more SSBs.

[0207] In one embodiment, the configuration information includes at least one first parameter, wherein each first parameter is associated with one of at least one SSB.

[0208] For example, configuration information is configured per SSB, configuring the associated first parameter for one or a single SSB; in the case of multiple SSBs, each SSB is configured with the associated first parameter in this way.

[0209] In another embodiment, the configuration information includes at least one first parameter, wherein each first parameter is associated with a set of SSBs, wherein a set of SSBs includes multiple SSBs.

[0210] In this context, the SSB set can be replaced with the SSB group.

[0211] For example, configuration information is configured as a first parameter associated with one or a single SSB set, either per SSB set or per SSB group. In the case of multiple SSB sets, each SSB set is configured with an associated first parameter. Each SSB set may include one or more SSBs. For ease of description compared to the per SSB approach, this embodiment uses the example of each SSB set containing multiple SSBs. For the multiple SSBs within each SSB set, the associated first parameter is the same.

[0212] In some embodiments, the method of dividing SSB sets or grouping SSBs can be configured or indicated by the network device 102. For example, SSBs with similar coverage areas are grouped together or form an SSB set, or SSBs with similar number of covered terminals are grouped together or form an SSB set.

[0213] In some embodiments, the first parameter is used to indicate a proportional correspondence between the SSB associated with the first parameter and the number of random access opportunities (ROs) associated with the SSB. For example, the first parameter is used to indicate a correspondence between the first SSB associated with the first parameter and the number of random access channel opportunities (ROs) associated with the first SSB, wherein the first SSB is a subset of at least one SSB.

[0214] The first parameter can be associated with a specific SSB, a set of SSBs, or multiple SSBs within that set.

[0215] Optionally, a subset of SSBs can refer to one or more SSBs. In this embodiment, the first SSB is used to represent any one of at least one SSBs for description. For example, in the per SSB configuration method, the first SSB is associated with a first parameter. In this case, the first parameter associated with the first SSB can be different from or the same as the first parameter associated with other SSBs. In the per SSB set method, the SSB set or SSB group to which the first SSB belongs is associated with a first parameter. That is, in this case, the first SSB is associated with the same first parameter as other SSBs in its SSB set.

[0216] For example, in the per SSB mode, the first parameter indicates the ratio between a specific SSB and the ROs associated with that SSB. Assuming the first parameter for SSB1 is set to 1 / 4, it means one SSB1 is associated with four ROs. Assuming the first parameter for SSB2 is set to 1 / 2, such as SSB-per-RO = 1 / 2, it means one SSB2 is associated with two ROs.

[0217] For example, in the per SSB set approach, the first parameter indicates the proportional relationship between multiple SSBs and ROs within a specific SSB set. Suppose an SSB set includes SSB3 and SSB4, and the first parameter configured for this SSB set is set to 1, indicating that one SSB3 is associated with one RO, and one SSB4 is associated with one RO.

[0218] In the above embodiments, during the configuration process, network device 102, in order to efficiently utilize RO resources and considering the different densities of terminals such as IoT devices distributed in different areas, can allocate more ROs to areas with higher device density, such as SSB2 or SSB3 as shown in Figure 1e, to meet the demand for high access capacity; while for areas with lower device density, such as SSB1 or SSB4, fewer ROs are allocated to avoid wasting UL resources and to cover directions or SSBs with lower device density where it is unnecessary to allocate too many ROs. This can better adapt to 6G IoT scenarios.

[0219] It is worth emphasizing that when configuring the first parameter per cell, the first parameter associated with multiple SSBs corresponding to that cell is the same. This disclosed embodiment differs from the per cell approach by configuring the first parameter per SSB or per SSB set, providing finer granularity and allowing for a more reasonable number of ROs to be configured for SSBs with different coverage areas.

[0220] In some embodiments, the first parameter can be reused from the parameter in the RACH configuration (RACH-ConfigCommon) information element (IE): ssb-perRACH-Occasion (SSB-per-RO).

[0221] In some embodiments, the first parameter may be represented by a new parameter, such as ssb-perRACH-OccasionAndCB-PreamblesPerSSB.

[0222] In one example, the IE reference for RACH configuration is as follows:

[0223] In some embodiments, the configuration information further includes a second parameter, which indicates the transmit power associated with an SSB or a set of SSBs, wherein a set of SSBs includes multiple SSBs.

[0224] Optionally, the configuration information can be configured per SSB, with each SSB having an associated second parameter; or, per SSB set, with each SSB set having an associated second parameter, where multiple SSBs within the SSB set have the same associated second parameter.

[0225] Optionally, the transmit power may include: the transmit power of the associated SSB, configured in a per SSB or per SSB set manner, which is beneficial to meet the coverage requirements of different SSB directions or areas.

[0226] Optionally, the transmit power may include: the power of the terminal uplink transmission under the associated SSB coverage (such as the power of transmitting MSG1), and the transmit power may be configured in a per SSB or per SSB set manner, which is beneficial to meet the uplink coverage requirements of different SSB directions or areas.

[0227] In some embodiments, terminal 101 receives configuration information and learns the first parameter and / or second parameter associated with different SSBs.

[0228] Step S2102: Determine the mapping between SSB and RO.

[0229] In some embodiments, terminal 101 and network device 102 can determine the mapping of SSB and RO respectively, and the two obtain a consistent mapping.

[0230] In some embodiments, this step may depend on the implementation of terminal 101 and network device 102. This disclosure is intended to describe the way SSB and RO are mapped, but does not limit the way this step is performed.

[0231] In one embodiment, such as in a per SSB configuration, step S2102 may include the following steps S2102-11:

[0232] Step S2102-11: Determine the RO of each SSB mapping based on the index order of at least one SSB and at least one first parameter.

[0233] In this step, the RO of each SSB mapping is determined based on the index order of the SSBs and the first parameter associated with each SSB.

[0234] In this step, the ROs of some SSB mappings in at least one SSB are determined sequentially at different frequency domain positions within the first time domain unit, according to the order of at least one SSB index from smallest to largest. The ROs of the remaining SSB mappings in the at least one SSB are determined sequentially within the time domain units following the first time domain unit.

[0235] For different time-domain units, each time-domain unit corresponds to multiple ROs arranged in the frequency domain.

[0236] The first time-domain unit is used to represent a certain time-domain unit, such as a time-domain unit associated with a certain SSB. In different frequency-domain locations of each time-domain unit, each frequency-domain location corresponds to a RO, or in other words, an RO or RO resource corresponds to a frequency-domain resource.

[0237] For example, this step may further include the following sub-steps:

[0238] The number of ROs associated with each SSB is determined based on the first parameter associated with each SSB.

[0239] Based on the SSB index order from smallest to largest and the number of ROs associated with each SSB, among the multiple ROs corresponding to the first time domain unit, the ROs mapped by the SSB with the smaller SSB index and the ROs mapped by the SSB with the larger SSB index are determined sequentially.

[0240] If multiple Returns (ROs) corresponding to the first time-domain unit are only associated with a portion of the SSBs in at least one SSB, then among the ROs corresponding to the time-domain units following the first time-domain unit, the ROs associated with the remaining SSBs in the at least one SSB are determined. That is, if the ROs of a certain time-domain unit have been mapped, but there are still remaining SSBs that have not been mapped, then the ROs of the remaining SSBs are mapped in the next time-domain unit.

[0241] For example, this step may further include the following sub-steps:

[0242] Based on a first parameter associated with the first SSB and the second SSB in at least one SSB, determine the number of ROs associated with the first SSB and the number of ROs associated with the second SSB.

[0243] Among the multiple ROs corresponding to the first time domain unit, the ROs of the first SSB mapping and the second SSB mapping are determined sequentially.

[0244] Here, the first SSB and the second SSB are used to represent two SSBs with different indices in at least one SSB, where the index of the first SSB is less than the index of the second SSB, and the RO of other SSB mappings can be determined based on the examples of the first SSB and the second SSB.

[0245] If multiple Returns (ROs) corresponding to the first time-domain unit are only associated with a portion of the SSBs in at least one SSB, then among the ROs corresponding to the time-domain units following the first time-domain unit, the ROs associated with the remaining SSBs in the at least one SSB are determined. That is, if the ROs of a certain time-domain unit have been mapped, but there are still remaining SSBs that have not been mapped, then the ROs of the remaining SSBs are mapped in the next time-domain unit.

[0246] For ease of understanding, please refer to the following example:

[0247] In one example, taking Figure 2b as an example, assuming the number of SSBs is 4, namely SSB1 to SSB4, and the random access association period (SSB / RACH Association Period) = 3, that is, one random access association period includes 3 RACH configuration periods. The first parameter of the association is configured for each SSB in a per SSB manner, where...

[0248] The first parameter associated with SSB1 takes the value of 1 (e.g., SSB-per-RO = 1), meaning that one SSB1 is associated with one RO.

[0249] The first parameter of the SSB2 association takes the value of 1 / 4 (e.g., SSB-per-RO = 1 / 4), meaning that one SSB2 is associated with 4 ROs;

[0250] The first parameter of the SSB3 association takes the value of 1 / 4 (e.g., SSB-per-RO = 1 / 4), meaning that one SSB3 is associated with 4 ROs;

[0251] The first parameter of the SSB4 association takes the value of 1 (e.g., SSB-per-RO = 1), meaning that one SSB4 is associated with one RO.

[0252] During the mapping process, within a random access association cycle, mapping is performed according to the index order of SSB1 to SSB4. First, in the first time-domain unit, the RO associated with SSB1 is determined. Following the frequency domain order, SSB1 is associated with the first of the four ROs corresponding to the first time-domain unit, and SSB1 mapping is complete. The next SSB is SSB2, which is then associated with the remaining three ROs in the first time-domain unit, completing the mapping for the first time-domain unit, but the SSB mapping is not yet complete. Mapping continues in subsequent time-domain units, such as SSB2 being mapped or associated with the first RO in the second time-domain unit, completing SSB2 mapping. The next SSB is SSB3, and similarly to SSB2, the four ROs associated with SSB3 are mapped sequentially in the frequency domain first, then the time domain, in subsequent time-domain units, such as the third time-domain unit. SSB4 is then mapped or associated sequentially with the second RO in the third time-domain unit, thus completing the mapping of all four SSBs.

[0253] It is understood that terms such as mapping, association, correspondence, or determination can be used interchangeably. The description of this embodiment is for illustrative purposes only; for example, during the mapping process, mapping can also be performed in descending order of SSB index.

[0254] In another embodiment, such as in a per SSB set configuration, step S2102 may include the following steps S2102-21:

[0255] Step S2102-21: Determine the RO of each SSB mapping according to the index order of different SSB sets and the at least one first parameter.

[0256] Optionally, the index of an SSB set can be determined based on the indices of the SSBs within that SSB set. For example, the index of an SSB set is the smallest SSB index among the multiple SSBs contained in the SSB set. For instance, if an SSB group includes SSB1 and SSB4, the index of that SSB group can be considered as the index of SSB1.

[0257] In this step, the RO of each SSB mapping is determined based on the index order of the SSB set and the first parameter associated with each SSB group.

[0258] In this step, the ROs of some SSB sets are determined sequentially in ascending order of their indexes within the first time domain unit at different frequency domain positions. The ROs of the remaining SSB sets are determined sequentially in time domain units after the first time domain unit. Within each SSB set, the ROs are mapped in ascending order of the SSB indices within the SSB set.

[0259] For example, this step may further include the following sub-steps:

[0260] The number of ROs associated with each SSB is determined based on the first parameter associated with each SSB set.

[0261] Based on the SSB set index order from smallest to largest and the number of ROs associated with each SSB, among the multiple ROs corresponding to the first domain unit, the ROs mapped to the SSB set with the smaller SSB set index and the ROs mapped to the SSB set with the larger SSB set index are determined sequentially.

[0262] Within each SSB set, the RO of the SSB mapping with the smaller SSB index is determined first, and then the RO of the SSB mapping with the larger SSB index is determined.

[0263] If multiple ROs corresponding to the first time domain unit are only associated with some SSBs contained in different SSB sets, then among the ROs corresponding to the time domain units after the first time domain unit, determine the ROs associated with the remaining SSBs contained in different SSB sets.

[0264] For ease of understanding, please refer to the following example:

[0265] In one example, taking Figure 2c as an example, assuming the number of SSBs is 4, namely SSB1 to SSB4, and the random access association period (SSB / RACH Association Period) = 3, that is, one random access association period includes 3 RACH configuration periods. The first parameter of the association is configured for each SSB set in a per SSB set manner, where:

[0266] SSB set 1 or SSB group 1 includes: SSB1 and SSB4. The first parameter associated with SSB set 1 is 1 (e.g., SSB-per-RO = 1), that is, SSB1 and SSB4 in this SSB set are each associated with 1 RO.

[0267] SSB set 2 or SSB group 2 includes: SSB2 and SSB4. The first parameter associated with this SSB set 2 takes the value of 1 / 4 (e.g., SSB-per-RO = 1 / 4), that is, SSB2 and SSB3 in this SSB set are each associated with 4 ROs.

[0268] During the mapping process, within one random access association cycle, mapping is performed in the order of SSB set 1 to SSB set 2. First, in the first time-domain unit, the ROs associated with SSB set 1 are determined. In the first time-domain unit, following the frequency domain order and ascending order of the group index, the RO associated with SSB1 is the first RO in the first time-domain unit, and the RO associated with SSB4 is the second RO in the first time-domain unit. The mapping of SSB set 1 is then complete. In SSB set 2, SSB2 is associated with the remaining two ROs in the first time-domain unit and the first two ROs in the second time-domain unit. Similarly, SSB3 is associated with the remaining two ROs in the second time-domain unit and the first two ROs in the third time-domain unit. The mapping of SSB set 2 is then complete.

[0269] In step S2103, based on configuration information and beam measurement, terminal 101 initiates a random access procedure according to the RACH resource corresponding to a specific beam.

[0270] In some embodiments, the specific beam is the beam whose measurement result, determined by the terminal 101 based on beam measurement, meets a threshold, i.e., the beam with better reception quality.

[0271] Optionally, in a scenario where network device 102 transmits downlink information in a beam sweeping manner, terminal 101 can receive and measure information or signals from different beams to determine the beam with better reception quality.

[0272] In some embodiments, the RACH resource corresponding to the particular beam may include: RO or RO resource, and / or Preamble.

[0273] In some embodiments, terminal 101 sends MSG1 on the RO corresponding to the specific beam to initiate a random access procedure.

[0274] Optionally, the MSG1 sent by terminal 101 may carry the corresponding Preamble.

[0275] In some embodiments, after receiving MSG1, network device 102 can determine the SSB associated with RO and / or Preamble based on RO and / or Preamble corresponding to MSG3, thereby determining the direction or area where terminal 101 is located.

[0276] Optionally, in subsequent communications, network device 102 may send specific information or data to terminal 101 in the direction of SSB.

[0277] In step S2104, network device 102 sends instruction information to terminal 101.

[0278] In some embodiments, the indication information is used to indicate the updated configuration information.

[0279] In some embodiments, network device 102 may determine whether to perform step S2104 based on the actual scheduling situation.

[0280] For example, if the network side has a high transmission load or a high probability of access conflict during the random access process performed by terminal 101, network device 102 can send indication information to adjust the parameters of random access, such as adjusting the configuration of the first parameter.

[0281] In some embodiments, the indication information includes at least one of the following:

[0282] The first parameter is associated with a new SSB or SSB set;

[0283] The new value of the first parameter;

[0284] The updated second parameter.

[0285] In this embodiment, the value of the first parameter can be adjusted, such as changing the value of ssb-perRACH-OccasionAndCB-PreamblesPerSSB.

[0286] Alternatively, the SSB or SSB set associated with the first parameter can be adjusted, such as changing the SSB or SSB set associated with ssb-perRACH-OccasionAndCB-PreamblesPerSSB.

[0287] In some embodiments, the indication information can be sent via MSG2. For example, as in a RAR file indicating changes to configuration information.

[0288] In some embodiments, the indication information can be sent via paging DCI or system broadcast to indicate changes in configuration information.

[0289] In some embodiments, terminal 101 receives the aforementioned instruction information.

[0290] In step S2105, after receiving the indication information, terminal 101 re-initiates the random access procedure based on the indication information.

[0291] In some embodiments, after receiving the indication information, terminal 101 stops the random access procedure based on the original configuration information, or in other words, stops the current random access procedure. Based on the indication information, i.e., the updated configuration information, it re-initiates the random access procedure.

[0292] For example, taking the per SSB configuration as an example, assuming that the original value of the first parameter of SSB1 is 1 / 4, if the indication information indicates that the value of the first parameter has changed and the value of the first parameter of SSB1 becomes 1, then the terminal 101 can resend MSG1 on the RO associated with the SSB1 based on the RO mapped by SSB1.

In other words, it supports configuring the number of Returns associated with each SSB, thereby efficiently utilizing UL Return resources while ensuring random access capacity in high-density user deployment areas.

[0345] In one embodiment, for the initial configuration, or the random access configuration:

[0346] Network devices can configure the proportional relationship between the ROs associated with each SSB or SSB group through system broadcast information. For example, the network side can configure at least one parameter, ssb-perRACH-OccasionAndCB-PreamblesPerSSB, with each parameter associated with one SSB or a group of SSBs.

[0347] In an optional example (Option 1) of this embodiment: during the SSB and RO mapping process, the RO associated with the SSB is determined according to the SSB index order and the configuration of the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB corresponding to the SSB. The mapping order to the RO is first the frequency domain of the RO, then the time domain.

[0348] In another alternative example (Option 2) of this embodiment: the RO associated with the SSB is determined according to the order of the SSB groups (the order of the groups is in ascending order of the smallest SSB code in the group), and then according to the order of the SSB index in the group in ascending order. The mapping order to the RO is first the frequency domain of the RO and then the time domain.

[0349] In this embodiment, optionally, the transmit power of each SSB can also be configured per SSB or per SSB group to meet the different coverage requirements of different areas.

[0350] In another embodiment, the configuration is optimized and adjusted as follows:

[0351] Based on the previous embodiment, if the network side detects high load or high collision probability during the random access procedure performed by the terminal, it can adjust the configuration of ssb-perRACH-OccasionAndCB-PreamblesPerSSB. The adjustment can target:

[0352] (1) Changes to the value of ssb-perRACH-OccasionAndCB-PreamblesPerSSB;

[0353] (2) ssb-perRACH-OccasionAndCB-PreamblesPerSSB is an SSB or SSB group associated with ssb-perRACH-OccasionAndCB-PreamblesPerSSB.

[0354] Alternatively, the above configuration changes can be made via RAR, paging DCI, or system broadcast.

[0355] In this embodiment, if the UE receives the above changes, then: the UE that is currently performing a random access procedure stops the current random access procedure and re-initiates the random access procedure as needed according to the new configuration.

[0356] In this embodiment of the disclosure, the number of ROs associated with each SSB can be different depending on the actual user distribution.
