[0185] In some embodiments, the access network device can be composed of a central unit (CU) and a distributed unit (DU), where the CU can also be referred to as a control unit. The CU-DU structure can split the protocol layers of the access network device, with some of the protocol layers being controlled by the CU and the rest of the protocol layers or all of the protocol layers being distributed in the DUs and controlled by the CU, but is not limited thereto.

[0186] In some embodiments, the core network device can be one device including one or more network elements, or can be multiple devices or device groups including all or part of the one or more network elements, respectively. The network element can be virtual or physical. The core network includes at least one of, for example, an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

[0187] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed in the embodiments of the present disclosure. Those skilled in the art can know that, as the system architecture evolves and new business scenarios appear, the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems.

[0188] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1A or part of the subject, but are not limited thereto. The subjects shown in FIG. 1A are exemplary, and the communication system can include all or part of the subjects in FIG. 1A, or can include other subjects other than those in FIG. 1A. The number and form of each subject is arbitrary, and the connection relationship between the subjects is exemplary. The subjects can not be connected or can be connected, and the connection can be in any manner, can be direct connection or indirect connection, and can be wired connection or wireless connection.

[0189] Embodiments of the present disclosure 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 (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based thereon, and the like. Further, a plurality of systems can be combined (for example, combination of LTE or LTE-A and 5G, and the like).

[0190] Optionally, a Random Access Channel Occasion (RO), which can also be referred to as an access opportunity, is not limited thereto.

[0191] Optionally, in a Non Terrestrial Network (NTN), the coverage ratio is Y / X, where X is the total number of beams that a satellite needs to cover, and Y is the number of beams that the satellite can transmit simultaneously due to its power limitation.

[0192] Optionally, the transmission of Synchronization Signal and Physical Broadcast Channel block (SSB) in NTN is beam-based transmission, and the transmission has a fixed pattern. In actual systems, a base station can not transmit some SSB beams. Therefore, the base station can further indicate the actually transmitted SSB beams and the SSB beams that are not actually transmitted in the System Information Block 1 (SIB1) or ServingCellConfigCommon through the ssb-PositionsInBurst information. When a UE selects a certain SSB beam according to the Reference Signal Receiving Power (RSRP) measurement and determines the SSB index of the beam, the appropriate RO and preamble can be selected to transmit the Physical Random Access Channel (PRACH) through the mapping relationship between the RO and the valid SSB index.

[0193] Optionally, the mapping relationship between the SSB and the RO and the preamble can be indicated by some parameters. Two common parameters are msg1-FDM and ssb-perRACH-OccasionAndCB-PreamblesPerSSB. Among them, msg1-FDM defines how many ROs there are on the same time resource and different frequency domain resources. ssb-perRACH-OccasionAndCB-PreamblesPerSSB defines how many SSBs correspond to one RO, and how many preambles correspond to one SSB.

[0194] Optionally, as shown in FIG. 1B, FIG. 1B shows a mapping relationship between SSB and RO and preamble, in which msg1-FDM = one (1), ssb-perRACH-OccasionAndCB-PreamblesPerSSB = one (1). In FIG. 1B, the horizontal axis represents time, and the vertical axis represents frequency.

[0195] Optionally, as shown in FIG. 1C, FIG. 1C shows another mapping relationship between SSB and RO and preamble, in which msg1-FDM = two (2), ssb-perRACH-OccasionAndCB-PreamblesPerSSB = one (1). In FIG. 1C, the horizontal axis represents time, and the vertical axis represents frequency.

[0196] Optionally, as shown in FIG. 1D, FIG. 1D shows another mapping relationship between SSB and RO and preamble, in which msg1-FDM = two (2), ssb-perRACH-OccasionAndCB-PreamblesPerSSB = eight (8). In FIG. 1D, the horizontal axis represents time, and the vertical axis represents frequency.

[0197] Optionally, in a new radio non-terrestrial network (NR NTN), in order to achieve full wave site coverage in the coverage area (footprint), beam cycle scanning can be performed. In FR1 <3 GHz (gigahertz), the maximum number of supported SSBs is 4, and according to the coverage ratio = 10% in the NTN, 40% of the area can be covered. Without increasing the number of SSBs, full-area coverage can be achieved by multiplexing SSB indexes (SSB indexes) in different areas, as shown in FIG. 1E, which shows a schematic diagram of multiplexing SSB indexes in different areas. In FIG. 1E, ms represents millisecond.

[0198] Optionally, in the case of binding between SSB index and area, since the network device needs to determine the SSB accessed by the terminal through the RO and / or preamble, the network device cannot determine which SSB under the area is accessed by the terminal according to the RO and / or preamble. And the terminal cannot effectively determine the random access occasion (RO) and / or preamble corresponding to the SSB under the area.

[0199] FIG. 2 is an interaction diagram of an information determination method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to an information determination method, which can be used in the communication system 100, and the method comprises the following steps:

[0200] In step S2101, the network device sends first information.

[0201] The first information is used to indicate the correspondence between random access occasions ROs and / or preambles and areas and / or synchronization signal and physical broadcast channel blocks SSBs.

[0202] In some embodiments, the network device can send the first information to the terminal, and use the first information to indicate the correspondence between ROs and / or preambles and areas and / or SSBs to the terminal.

[0212] In this way, the network device can flexibly indicate various possible correspondences between ROs and / or preambles and areas and / or SSBs to the terminal, which can effectively improve the flexibility of indication and effectively adapt to individualized communication scenarios.

[0213] In some embodiments, the first information is carried based on at least one of the following: system information block 1 (SIB1) information; UE-specific information. In this way, the flexibility of sending the first information can be effectively improved.

[0214] In some embodiments, the network device can send the terminal SIB1 information, which can contain the first information.

[0215] In some embodiments, the network device can send the terminal UE-specific information, which can contain the first information.

[0216] In some embodiments, the network device can send the terminal SIB1 information and UE-specific information, and jointly indicate the first information through the SIB1 information and the UE-specific information.

[0217] In some embodiments, the first information includes a first parameter, and the first parameter is used to indicate the correspondence between the RO and the SSB index, and / or at least one preamble corresponding to the SSB index; wherein the RO is associated with a zone identifier, and the zone identifiers associated with different ROs are different.

[0218] In some embodiments, the first parameter is, for example, the ssb-perRACH-OccasionAndCB-PreamblesPerSSb parameter.

[0219] In some embodiments, the correspondence between the RO and the SSB index may, for example, be that one RO can correspond to at least one SSB, and one SSB can correspond to at least one RO, and there is no limitation thereon.

[0220] That is to say, if the first information contains the first parameter, the RO in the first parameter can have a one-to-one correspondence with the zone identifier, that is, one RO is associated with one zone identifier, and the zone identifiers associated with different ROs are different.

[0221] In some embodiments, the first information includes a first parameter, and the first parameter is used to indicate the correspondence between the RO and the SSB index, and / or at least one preamble corresponding to the SSB index; wherein the preamble is associated with a zone identifier, and the zone identifiers associated with different preambles are different.

[0222] That is to say, if the first information contains the first parameter, the preamble in the first parameter can have a one-to-one correspondence with the zone identifier, that is, one preamble is associated with one zone identifier, and the zone identifiers associated with different preambles are different.

[0223] In some embodiments, if the first information contains the first parameter, the preamble in the first parameter can have a one-to-one correspondence with the zone identifier, and the RO in the first parameter can also have a one-to-one correspondence with the zone identifier, that is, one preamble is associated with one zone identifier, one RO is associated with one zone identifier, the zone identifiers associated with different preambles are different, and the zone identifiers associated with different ROs are also different.

[0224] In some embodiments, the first information includes a second parameter, and the second parameter is used to indicate at least one RO of the same time domain resource and different frequency domain resources; wherein the frequency domain resource is associated with one zone identifier, and the zone identifiers associated with different frequency domain resources are different.

[0225] In some embodiments, the second parameter can be, for example, a msg1-FDM parameter.

[0226] In some embodiments, if the first information contains the second parameter, the frequency domain resource indicated by the second parameter can have a one-to-one correspondence with the zone identifier, that is, one frequency domain resource is associated with one zone identifier, and the zone identifiers associated with different frequency domain resources are different.

[0227] In some embodiments, the first parameter and the second parameter can be jointly contained in the first information, and any of the above possible ways or a combination of any possible ways can be used to indicate the zone identifier, so as to effectively improve the flexibility and effectiveness of the indication of the first information, and effectively adapt to personalized communication scenarios.

[0228] In some embodiments, the network device can send second information to the terminal, and the second information is used to indicate the zone identifier to which the SSB actually sent by the network device belongs. Thus, the terminal can be effectively indicated in which zones the SSB is actually sent.

[0229] In some embodiments, the terminal can determine in which zones the network device actually sends the SSB according to the second information sent by the network device.

[0230] In some embodiments, the zone indicated by the first information is the zone to which the SSB actually sent by the network device belongs. That is, when mapping the RO and / or preamble, the mapping can be performed only based on the zone in which the network device actually sends the SSB, which can effectively reduce the indication overhead of the first information, and can better adapt to actual communication scenarios.

[0231] In step S2102, the terminal determines the RO and / or preamble corresponding to the first SSB of the first zone according to the first information.

[0232] The first SSB of the first area refers to a first SSB of a first area accessed by the terminal. It can also be referred to as a first SSB of a first area selected by the terminal.

[0233] In some embodiments, the terminal can receive first information sent by the network device.

[0234] In some embodiments, the terminal can determine the RO and / or preamble corresponding to the first SSB of the first area by referring to the first information.

[0235] In some embodiments, the terminal can use the RO and / or preamble corresponding to the first SSB of the first area to send a physical random access channel (PRACH), or information 1 (msg1), or the PRACH and msg1.

[0236] In some embodiments, the first area and the other area belong to the same cell, and the system information block (SIB) information carried by different areas is the same. Thus, different areas can share the same SIB information. That is, the first area is one of multiple areas, the multiple areas are areas under the same cell, and the SIB information carried by different areas under the same cell is the same.

[0237] In some embodiments, the first area and the second area belong to different cells, and different areas are distinguished by different cell identifiers (IDs), which can also be referred to as area identifiers. The system information block information carried by different areas is different.

[0238] In some embodiments, the terminal can determine the area identifier of the first area and the SSB index of the first SSB, and determine the RO and / or preamble corresponding to the area identifier and the SSB index according to the first information. Thus, the RO and / or preamble corresponding to the first SSB of the first area can be quickly and accurately determined.

[0239] The area identifier of the first area can be used to identify the first area. The SSB index of the first SSB can be used to identify the first SSB. Each area can correspond to an area identifier, and the area identifiers of different areas are different. Each SSB can correspond to an SSB index, and the SSB indexes of different SSBs are also different.

[0240] In some embodiments, the terminal can determine a region identifier of the first region, and determine an SSB index of the first SSB, and determine, from the correspondence indicated by the first information, an RO and / or a preamble corresponding to the region identifier and the SSB index, and take the RO and / or the preamble corresponding to the region identifier and the SSB index as the RO and / or the preamble corresponding to the first SSB of the first region.

[0241] In step S2103, the terminal transmits a PRACH and / or an information 1 msg1 using the corresponding RO and / or preamble.

[0242] In some embodiments, after determining the RO and / or the preamble corresponding to the first SSB of the first region according to the first information, the terminal can transmit a PRACH, or transmit a msg1, or transmit a PRACH and a msg1 to the network device using the RO and / or the preamble corresponding to the first SSB of the first region.

[0243] In some embodiments, the transmission of the PRACH by the terminal can be understood as the transmission of a specific preamble on a specific RO resource.

[0244] In step S2104, the network device receives the PRACH and / or the msg1.

[0245] In some embodiments, the network device can receive the PRACH and / or the msg1 transmitted by the terminal.

[0246] In some embodiments, the network device can determine the first SSB of the first region selected by the terminal according to the received PRACH and / or msg1.

[0297] The present disclosure provides a method of mapping RO to SSB ID (also referred to as SSB index, SSB index) and area ID (area identifier) in the case of SSB and area binding in NTN network.

[0298] The following is an exemplary introduction to the above method.

[0299] Optionally, embodiments:

[0300] Point 1: The network can determine the areaID and SSB index selected by the UE through the PRACH / msg1 information sent by the UE.

[0301] Point 2: The UE determines the time-frequency resource location and / or preamble of the RO of different areas according to the indication information sent by the network and / or the pre-defined mapping rule.

[0302] Point 3: The SIB information carried in the entire cell, even in different areas, is the same.

[0303] Point 4: Differentiated according to the corresponding parameters in ssb-perRACH-OccasionAndCB-PreamblesPerSSB.

[0304] Solution 1: Differentiated by RO.

[0305] Example: ssb-perRACH-OccasionAndCB-PreamblesPerSSB={oneHalf, n4}, 1 SSB corresponds to two ROs, which can distinguish which RO is which area, such as even RO corresponds to area#1 and odd RO corresponds to area#2. Similarly, this method can be applied to 1 SSB corresponding to 4 ROs, 8 ROs, etc.

[0306] Solution 2: Differentiated by preamble.

[0307] Example: ssb-perRACH-OccasionAndCB-PreamblesPerSSB={one, n4}, for 1 SSB corresponding to 1 RO, each SSB has 4 preambles, preamble#1 is used for area#1 and preamble#2 is used for area#2.

[0308] Point 5: Differentiated according to msg1-FDM.

[0309] Solution 1: Differentiated by RO.

[0310] Example: msg1-FDM=2, then on the same time domain resource, frequency domain#1 corresponds to area#1 and frequency domain 2 corresponds to area#2.

[0311] The solutions in points 4 and 5 can also be used jointly.

[0312] The indication information is sent through SIB1 information, such as included in the parameter ServingCellConfigCommonSIB.

[0313] The indication information is sent through UE-specific information, such as included in the parameter ServingCellConfigCommon.

[0314] The indication information can also include Area activation signaling, such as ssb-PositionsInBurst, to indicate which Areas the base station actually transmits, and the RO mapping is also mapped to the Areas actually transmitted by the base station.

[0315] The Area activation signaling can be included in ServingCellConfigCommonSIB or ServingCellConfigCommon.

[0316] In some embodiments, the indication information described above can be an optional example of the first information.

[0317] In some embodiments, the ssb-perRACH-OccasionAndCB-PreamblesPerSSb described above can be an optional example of the first parameter.

[0318] For example, if the first parameter is ssb-perRACH-OccasionAndCB-PreamblesPerSSb, the first parameter (e.g. oneHalf) in ssb-perRACH-OccasionAndCB-PreamblesPerSSb indicates the correspondence between RO and SSB index, and when the first parameter is oneHalf, it means that one SSB corresponds to two ROs. The second parameter (e.g. n4) in ssb-perRACH-OccasionAndCB-PreamblesPerSSb indicates at least one preamble corresponding to the SSB index, and when the second parameter is n4, it means that each SSB has 4 preambles.

[0319] In some embodiments, in the first scheme of the fourth point described above, a region identifier can be associated with the RO indicated by ssb-perRACH-OccasionAndCB-PreamblesPerSSb, and the region identifiers associated with different ROs are different. Thus, different regions can be distinguished based on the RO indicated by ssb-perRACH-OccasionAndCB-PreamblesPerSSb.

[0320] In some embodiments, in solution 2 of the fourth point above, an area identifier can be associated with each preamble indicated by ssb-perRACH-OccasionAndCB-PreamblesPerSSb, and the area identifiers associated with different preambles are different. Thus, different areas can be distinguished based on the preambles indicated by ssb-perRACH-OccasionAndCB-PreamblesPerSSb.

[0321] In some embodiments, solutions 1 and 2 of the fourth point above can be combined to distinguish different areas.

[0322] In some embodiments, msg1-FDM described above can be an optional example of the second parameter.

[0323] For example, if the second parameter is msg1-FDM, and msg1-FDM = 2, it means two ROs with the same time domain resource and different frequency domain resources, where each frequency domain resource is associated with an area identifier, and the area identifiers associated with different frequency domain resources are different.

[0324] In some embodiments, in the fifth point above, an area identifier can be associated with each frequency domain resource indicated by msg1-FDM, and the area identifiers associated with different frequency domain resources are different. Thus, different areas can be distinguished based on the frequency domain resources indicated by msg1-FDM.

[0325] In some embodiments, the Area activation signaling can be an optional example of the second information.

[0326] In some embodiments, the second information can be included in the first information, or the second information can also be included in ServingCellConfigCommonSIB or ServingCellConfigCommon, and no limitation is made in this regard.
