[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese Patent Application No. 202410403894.2 filed in China on April 4, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The embodiments of the present disclosure relate to the field of communication technology, and in particular to a communication processing method, apparatus, device, and readable storage medium. Background Art

[0004] In a Non-Terrestrial Networks (NTN) system, satellite communications are used to provide communication services to terrestrial users. A first communication device (eg, User Equipment (UE)) in the NTN system provides communication services to terrestrial users using satellite communications.Due to the problems of ultra-long transmission delay and ultra-large channel transmission fading caused by the ultra-high position of the satellite, network equipment is currently unable to use traditional timing advance (TA) technology to inform the UE of the time advance for uplink (UL) transmission based on the signal and / or data sent by the first communication device, or the random access process. Instead, the UE performs link time and frequency compensation based on its own Global Navigation Satellite System (GNSS) position, ephemeris information, etc., thereby realizing UL time and frequency synchronization technology. However, this relies on the UE supporting the acquisition of GNSS position, but not all UEs support the acquisition of GNSS position, or it cannot be acquired in some environments. The UE needs to obtain its own position information through the information of the network device, but in the current communication technology, the positioning of the fifth generation mobile communication technology (5th Generation Mobile Communication The 5G technology solution is mainly for connected and inactive states, and does not support idle UEs being able to obtain their own location information, and network equipment is also unable to obtain the location information of idle UEs. On the other hand, due to the extremely long transmission delay caused by the ultra-high position of the satellite, the problem of extremely large channel transmission fading and the extremely large area coverage (usually ten times that of ground coverage), coupled with the limited antenna capabilities of high-altitude equipment such as satellite networks, the beam area that satellite network equipment can simultaneously transmit at a certain moment, that is, the coverage provided at a certain moment is insufficient to cover the area of ​​the entire cell. However, as mentioned above, the current network equipment is also unable to obtain the location information of idle UEs. Therefore, when an idle UE has data and / or signaling to send, the network equipment is unable to send limited beam resources to the idle UE that needs service triggering because it does not know the location information of the idle UE, resulting in the data and / or signaling being unable to be sent in a timely manner. Moreover, even in the connected state, it is impossible to efficiently switch between different beam types. In addition, due to the extremely large area coverage (usually ten times that of ground coverage) caused by the ultra-high position of the satellite, the related technology for multicast broadcast services (MBS) is not suitable for the 5G technology. The service area identifier (SAI) broadcast by the satellite MBS has changed from including multiple cells to having multiple MBS broadcasts in one cell. Due to the lack of location information, the UE cannot normally receive the broadcast service under the satellite. Summary of the Invention

[0121] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0122] The term "comprise" and any variations thereof in the specification and claims of the present disclosure are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to the process, method, product, or apparatus. In addition, the use of "and / or" in the specification and claims to indicate at least one of the connected objects, such as A and / or B, means that A alone, B alone, and both A and B are included.

[0123] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0124] For ease of understanding, let’s first introduce the following technical points:

[0125] 1. About multi-round-trip time (Multi-RTT): the round-trip time between multiple stops.

[0126] Principle: The UE and multiple base stations (or signal transceiver points) exchange reference signals. The UE's location is determined based on the time difference between the UE's received and transmitted signals, and the time difference between the base station's (next generation Node B, gNB) received and transmitted signals, as shown in Figure 1.

[0127] Multi-RTT is a positioning method that combines uplink positioning and downlink positioning, and has higher positioning accuracy.

[0128] No need for users and base stations to be synchronized.

[0129] 2. About New Radio (NR) - Time Difference of Arrival (TDOA) signal arrival time difference.

[0130] Defines uplink and downlink TDOA positioning methods: When two base stations are used as center points, the difference between the user's position and the two center points forms a hyperbola. If another hyperbola exists, formed by the base station and the reference base station, the intersection of the two hyperbolas is the user's position (see Figure 2).

[0131] Downlink (DL)-TDOA is when a UE receives a downlink positioning reference signal (eg, Positioning Reference Signal (PRS)) from a base station and measures the time difference.

[0132] In UL-TDOA, the UE needs to transmit an uplink reference signal (eg, a sounding reference signal (SRS)), and the base station measures the time difference.

[0133] ·Requires users and base stations to be synchronized.

[0134] 3. About Enhanced Cell-ID (E-CID).

[0135] Enhanced Cell Identity (E-CID) positioning adds auxiliary information such as Time Advance (TA), Angle of Arrival (AOA), Reference Signal Receiving Power (RSRP), and Reference Signal Receiving Quality (RSRQ) to the Cell ID to improve positioning accuracy. See Figure 3.

[0136] Principle: The location of the base station in the serving cell is used as the user's location. The directionality of the sector antenna is combined to narrow the positioning area to a certain direction range. Alternatively, the TA and RSRP are combined to narrow the user's location to a concentric circle centered on the base station.

[0137] The advantages and disadvantages of the E-CID positioning method are:

[0138] Disadvantages: It is related to the coverage of the base station and the positioning accuracy is relatively low.

[0139] Advantages: Easy to implement, low cost, and applicable to all cellular networks; no software or hardware modifications are required on the first communication device side, and no new network entities need to be added on the network side.

[0140] Used as an auxiliary positioning method when other positioning methods fail.

[0141] 4. About uplink angle of arrival (UL-AOA).

[0142] UL-AOA is an angle-based positioning method that can locate the user's position when there are only two base stations. See Figure 4.

[0143] Principle: Each receiving antenna is at a different distance from the transmitting antenna, resulting in phase differences between the signals from different receiving antennas. Using this phase difference information, we can determine the AOA of the signal transmitted by the first communication device relative to the cellular base station channel.

[0144] Synchronization is not required, but the base station needs to be equipped with a larger antenna array to obtain more accurate angle information.

[0145] Factors affecting accuracy: AOA uses different antenna arrays and configurations due to different frequency bands; the number of antennas in the antenna array; and the distance between the user and the base station.

[0146] The related art has the following problems:

[0147] 1) Global Navigation Satellite System (GNSS) capability is one of the limitations of UEs in non-terrestrial networks (NTNs) in related technologies. This is because UEs need to use GNSS position information and ephemeris information to perform time and frequency synchronization. However, many UEs do not implement a GNSS receiver or cannot use it in different environments.

[0148] 2) Positioning 5G solutions are mainly aimed at connected and inactive states, and it can be seen that positioning depends on the distance and angle from the UE to multiple stations, which intersect to form the UE's location range or a point. The more stations involved, the more curves there are, and the higher the positioning accuracy. However, in related technologies, it is required to study positioning technology in single-track scenarios, and the relevant solutions cannot meet the needs. If the positioning curves of the UE are intersected by a satellite at different time points, there will be problems such as accuracy error and signal failure; and the UE needs to use location information and ephemeris information to perform time-frequency synchronization during initial access. Therefore, a positioning determination method for idle states and single-track satellites is needed.

[0149] The communication system applied in the embodiment of the present disclosure may include a network device, a network node and a first communication device (also referred to as a first network node, a first communication node, etc.); the network node includes an application server, and the first communication device includes a terminal.

The first communication device can be one or more base stations, transmitting points, receiving points, central units, distribution units, indoor baseband processing units (Building Base band Unite, BBU), remote radio units (Remote Radio Unit, RRU), relays, integrated access and backhaul (IAB), smart metasurfaces, communication balloons, flying aircraft base stations, antennas, satellite base stations, terminals using sidelink communication, etc.; the first communication device can also be a terminal, or a module with other specific communication functions; the first communication device can also be an application server that provides perception functions and / or artificial intelligence (AI) functions, etc.; the first communication device can also be a core network node, such as a user plane function (UPF), an application function (AF), a mobility management entity (MME), an access and mobility management function (AMF), a core network integrated device, or other network elements used to establish a connection.

[0493] In one embodiment of the present disclosure, the method further comprises:

[0494] The second communication device determines the sub-area and / or sub-area group of the first communication device according to the random access information sent by the first communication device.

[0495] In the present disclosure, a second communication device sends first information and / or a first signal to a first communication device, so that the first communication device can perform a first operation based on the first information and / or the first signal, and the first operation includes at least one of the following: positioning, beam selection, switching between the first beam and the second beam, communication of data and / or signaling, determining resource information for communication of data and / or signaling, and ensuring normal communication between the first communication device and the satellite.

[0496] Example 1:

[0497] 7 , when the UE enters the network connection of the NTN, the UE receives first information and / or a first signal, where the first information and / or the first signal may be a system message or other information / signaling.

[0498] Optionally, the first signaling and / or the first signal is used to configure data related to idle state positioning.

[0499] Optionally, the first information may be a newly added dedicated SIB (NTNIdlePosSIB).

[0500] The second communication device can carry n third information in the first information, where the third information is used to indicate the correspondence between the PRS resource and the PRS transmission time, and the UE corresponds according to the current time point and the time in the ephemeris information; further, the sixth information in the first information indicates an indication of merging the measurement results of the PRS at n transmission time points of the UE.

[0501] Among them, the transmission time point can be absolute time information, or the transmission time point can also be relative time information, that is, a form of period plus offset (offset); because the delay from the second communication device to the first communication device on the ground is extremely long, in order for the UE to clearly understand the specific transmission time point of the received PRS in a specific period range or system frame number (SFN), super frame number (super SFN) value, etc.

[0502] Optionally, the first information and / or the first signal, when used to configure data related to idle state positioning, may be supplemented with at least one of a reference super frame number (super SFN), a reference SFN number, and a reference subframe number.

[0503] Optionally, the second communication device notifies the UE of at least one of the following: the maximum transmission delay and minimum transmission delay from the second communication device within the coverage area of ​​the second communication device to the UE; the maximum transmission delay and delta value; the minimum transmission delay and delta value; so that the UE can determine the specific transmission time point of the received PRS within a specific period range or SFN, super SFN value, etc.

[0504] For example, the DL PRS of the idle UE supports transmission and reception based on the synchronization signal block (Synchronization Signal and PBCH block, SSB) beam, and supports flexible time domain resource and frequency domain resource configuration, such as:

[0505] At time T0, the second communication device configures DL PRS frequency layer 0, 1->Transmission and Receiving Point (TRP)->DL PRS resource set->DL PRS resource for the UE;

[0506] At time T1, the second communication device configures DL PRS frequency layer 2, 3->TRP->DL PRS resource set->DL PRS resource for the UE;

[0507] At time T2, the second communication device configures DL PRS frequency layer 4, 5->TRP->DL PRS resource set->DL PRS resource for the UE;

[0508] If the second communication device supports a limited number of DL PRS frequency layers, for example, only two layers, the following configuration method may be used:

[0509] At time T0, the second communication device configures DL PRS frequency layer0,1->TRP->DL PRS resource set1,2->DL PRS resource for the UE;

[0510] At time T1, the second communication device configures DL PRS frequency layer 0, 1->TRP->DL PRS resource set 3, 4->DL PRS resource for the UE;

[0511] At time T2, the second communication device configures DL PRS frequency layer0,1->TRP->DL PRS resource set5,6->DL PRS resource for the UE;

[0512] Optionally, the UE determines the sub-area and / or sub-area group in the ephemeris information where the second communication device is currently located based on the resource configuration information of different PRSs; and the UE determines the relative sub-area and / or sub-area group to the satellite based on the results of the measured PRS; thereby further clarifying the sub-area and / or sub-area group range where the UE is located based on the sub-area and / or sub-area group of the second communication device and the relative sub-area and / or sub-area group of the first communication device and the second communication device; then the UE merges and derives the sub-area and / or sub-area group of the first communication device based on the measurement results of other PRS signals that need to be merged in the PRS information.

[0513] For example, the first communication device first measures the arrival time T of the PRS sent by the second communication device at time T0. 0a Then, according to the PRS transmission time in the PRS configuration information, the ephemeris sub-region and / or sub-region group P0 of the second communication device at that time is deduced; then the first communication device specifically measures the arrival time T of the PRS sent by the second communication device at time T1 1a Then, according to the PRS transmission time in the PRS configuration information, the ephemeris sub-region and / or sub-region group P1 of the second communication device at that time is deduced; then the first communication device sets T 1a -T 0a -(T1-T0), the arrival time difference RSTD of the positioning reference signal is obtained; then the sub-area and / or sub-area group of the second communication device at the two time points are used as the focus of the hyperbola, and two hyperbolas are constructed with RSTD to determine the sub-area and / or sub-area group of the first communication device.

[0514] Optionally, when the resource location of a DL PRS collides with a downlink SSB or paging message, the second communication device may discard the PRS signal and send downlink SSB, paging message, and other signals. Correspondingly, the first communication device needs to understand this rule and automatically ignore the resource location of the PRS that collides with the downlink SSB or paging message.

[0515] Optionally, if the location change of the UE does not exceed a threshold, the above process is not triggered.

[0516] Example 2

[0517] When a UE enters the NTN system, it receives the SSB, which is a combination of the synchronization signal and the PBCH block. It consists of three parts: the Primary Synchronization Signals (PSS), the Secondary Synchronization Signals (SSS), and the Physical Broadcast Channel (PBCH), as shown in Figure 11.

[0518] ①SSB occupies a total of 4 Orthogonal Frequency Division Multiplexing (OFDM) symbols in the time domain and a total of 240 subcarriers (20 Physical Resource Blocks (PRBs)) in the frequency domain.

[0519] ②PSS is located in the middle 127 subcarriers of symbol 0.

[0520] ③The SSS is located in the middle 127 subcarriers of symbol 2. To protect the PSS and SSS, they have different subcarrier Set 0 at both ends.

[0521] ④PBCH (which contains the Master Information Block (MIB) message, which contains the system frame number, bandwidth information, and antenna configuration) is located in symbols 1, 3, and 2. Symbols 1 and 3 occupy all subcarriers 0 to 239, and symbol 2 occupies the subcarrier Set excluding the SSS subcarriers and the SSS protection subcarriers.

[0522] ⑤All subcarriers except 0.

[0523] ⑥ The De-Modulation Reference Signal (DM-RS) is located in the middle of the PBCH, on symbol 1 / 3, with 60 per symbol, spaced 4 subcarriers apart.

[0524] ⑦In 5G, the synchronization signal and PBCH are combined into one.

[0525] ⑧When the first communication device is turned on, it first searches for the primary and secondary synchronization signals to obtain downlink time and frequency synchronization. After searching for the synchronization signal, the center frequency of the cell is obtained. Long Term Evolution (LTE) has a bandwidth of 20M. After obtaining the center frequency of the cell, PBCH can also be easily obtained (because PBCH is also on the center frequency of the cell). However, the minimum bandwidth of 5G is 100M. If it is not placed together with the synchronization signal, then the 5G search for PBCH is slow.

[0526] Because there are one or more SSBs in a cycle, each SSB is marked with an ID. Different SSB IDs often correspond to different beam directions.

[0527] When the beam in the cell is a large range, the large beam directly corresponds to the range of its communication radiation. However, in another scenario, the frequency increases exponentially, so the coverage range of the 5G beam is greatly reduced. Then when sending some broadcast information, it no longer uses the coverage form but the beam scanning form. At a certain moment, the energy is concentrated in a certain direction, so this direction can send the signal farther, but other directions cannot receive the signal. The next moment, it is sent in another direction. Finally, the beam continuously changes direction to achieve coverage of the entire cell.

[0528] The SSB ID is designed for beam scanning. Each of several SSB IDs corresponds to a beam scanning direction, resulting in an SSB for each direction. These SSBs are called an SSB set, and all SSBs in an SSB set must be within the same half-frame. The SSB set period for a terrestrial network cell can be 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms. The SSB set period can be indicated in the System Information Block 1 (SIB1). However, during the initial cell search, the UE has not yet received SIB1 and therefore searches for SSBs at a default period of 20ms. However, in some scenarios, the antenna capacity and / or transmission power of the network equipment in the second communication equipment cell are limited. For example, due to the extremely long transmission delay caused by the extremely high position of the satellite, the problem of ultra-large channel transmission fading and the extremely large area coverage (usually ten times the ground coverage), and the limited antenna capacity of high-altitude equipment such as satellite networks, the beam area that the satellite network equipment can simultaneously transmit at a certain moment, that is, the coverage provided at a certain moment, is insufficient to cover the area of ​​the entire cell.

[0529] To ensure that users at all spot locations have the opportunity to access the satellite network, the satellite needs to periodically traverse all spot locations and send public information such as SSB, system messages, paging, and / or provide dedicated signaling / data communications. However, at a certain moment, only part of the cell area is covered by the beam. For example, in order to cover 1058 spot locations with a maximum of 32 simultaneously active beams, the SSB retransmission period needs to be greater than 170ms to achieve full coverage in terms of macro time. However, in the related art, during the initial cell search, the UE has not yet received the SSB and SIB1, so the protocol stipulates that the SSB will be searched according to the default 20ms period. If the first communication device cannot receive the SSB of the cell or cannot read the SIB message of the cell, it will be considered that the access to the cell has failed, or even that the cell is prohibited. If the SSB transmission period is more than 100ms, the first communication device in the related art will inevitably fail to access the cell frequently, and thus cannot obtain communication services. This is especially dangerous in rescue scenarios such as oceans, deserts, and outdoors covered by satellites. In order to adapt to the initial access requirements of communication cells in different scenarios, the initial access periods of UE are designed to be M1, M2, ..., Mn, etc., where M1, M2, ..., Mn are all natural numbers greater than 0.

[0530] Referring to Figure 10, for example, the initial access period of the UE is 20ms, 160ms, 380ms, 1400ms, and 2800ms. When the UE attempts to access the target cell, step 1: the first communication device first uses the M1 period of SSB (for example, 20ms) to access the target cell. If it fails, do not leave the cell immediately or stop accessing the target cell, such as considering the cell as bar (i.e., the cell has restricted access) or unavailable. Step 2: the first communication device uses the M2 period of SSB (for example, 160ms) to access the target cell again. If it fails, do not leave the cell immediately or stop accessing the cell, such as considering the cell as bar or unavailable. ...Step n: the first communication device uses the Mn period of SSB (for example, 1400ms) to access the target cell. Optionally, during this process, the UE may also try to access other cells if there are cells that can be detected.

[0531] Among them, the initial access period of the UE is M1, M2, ..., Mn parameters can be defined in the protocol, or saved on the UE side, or obtained in at least one of the same frequency band cell, the same type cell, the same track cell, the cell accessed for the last u times, and the adjacent cell, for example, in the system message, the Radio Resource Control (RRC) release message, etc., where u is an integer greater than 0; or, the PBCH is expanded to indicate the SSB period information in the PBCH, so that the UE can know the SSB period information of the cell when it detects the first SSB or PBCH.

[0532] (1) About the SSB time domain position.

[0533] According to different SSB subcarrier spacing, the SSB position in a half-frame will have different positions. In the terrestrial network, the New Radio (NR) divides the time domain position of the SSB into 5 different situations according to the different subcarrier spacing. For example, when the SSB subcarrier spacing is 15kHz, the position of the first SSB symbol is 2. When the carrier frequency is less than 3GHz, n = 0, 1, and the maximum number of beams is 4. When the carrier frequency is between 3G and 6GHz, n = 0, 1, 2, 3, and the maximum number of beams is 8. Figure 12 shows the position of the SSB in a time slot of a half-frame more intuitively. For different subcarrier spacings, the number of SSBs in an SSB set is also different. For example, the number of SSBs is equal to 4, 8, or 64.

[0534] In NTN cells, as mentioned above, some network devices have limited antenna capabilities and / or transmit power. Furthermore, the secondary communication device is far from the ground, has a large cell coverage area, and suffers from significant link fading, making it difficult for network devices to simultaneously cover all cell locations. Furthermore, because the SSB subcarriers are independent of the subcarriers in other time slots, the UE only needs to obtain the SSB and then the PBCH. By decoding the PBCH, it can determine the subcarrier spacing of the normal channels on the carrier. Furthermore, a shorter SSB also allows for more beam directions to be delivered in a shorter period of time.

[0535] Method 1: The second communication device first sends the first beam represented by the first SSB. The first SSB is sent periodically. Optionally, the second communication device configures the correspondence between at least two of the SSB, TCI state, QCL, CSI-RS, SRS, random access resources, Mapped Cell ID (mapped cell identifier), sub-area (and / or sub-area group) of the second communication device, and uplink resource information; the second communication device can configure the above correspondence in at least one of the system messages, RRC signaling, Media Access Control (MAC) signaling, and DCI signaling; this correspondence can be at least one of one-to-one, many-to-one, and one-to-many;

[0536] For example, a correspondence between each sub-area and / or sub-area group and at least one of CSI-RS, SSB, TCI state, QCL, CSI-RS, SRS, random access resource, Mapped Cell ID (mapped cell identifier), and uplink resource information;

[0537] Therefore, at least one of the following methods can be implemented:

[0538] The second communication device may determine the sub-area where the UE is located based on the received SRS signal sent by the UE and / or the resource for the UE to send the SRS signal; the second communication device may determine the sub-area where the UE is located based on the received preamble preamble sent by the UE and / or the random access resource for the UE to send the preamble preamble; the UE may select the preamble preamble corresponding to the sub-area and / or the random access resource corresponding to the preamble preamble sent based on the sub-area where the UE is located; the UE may select the SSB corresponding to the sub-area where the UE is located to receive at least one signaling and / or data in RAR signaling, MSG4, paging, and system messages;

[0539] For example, the correspondence between SSB and PRACH; and / or the correspondence between at least two types of SSB, PRACH, and sub-area information;

[0540] For example, corresponding relationship 1:

[0541] If Nr represents the mapping relationship between SSB and RO, the preamble corresponding to one RO is specified by the parameter Np.

[0542] If Nr < 1, it means that one SSB is mapped to multiple ROs, and each RO has Np consecutive CB preamble indexes (0 to R-1). For example, if the maximum number of preambles is 64, Nr = 1 / 8, and Np = 12, then Nr = 1 / 8, which means that one SSB is mapped to 8 ROs, and each RO has 12 consecutive CB preambles.

[0543] If Nr>=1, that is, one RO is mapped to multiple SSBs, SSBn has Np consecutive random access preambles (RApreambles), and the starting preamble index of each RO is n*N_total_preamble / Nr.

[0544] Nr=1, indicating that one SSB is mapped to one RO.

[0545] If the maximum number of preambles is 64, Nr = 2, and Np = 12, then if Nr = 2, it means that 2 SSBs are mapped to one RO (64 preambles), and each SSB is allocated 32 preambles;

[0546] SSB 0 starting preamble index = 0*64 / 2 = 0 preamble 0 to 31 (0 to 11 are CB preambles);

[0547] The starting preamble index of SSB 1 = 1*64 / 2 = 32 preambles 32 to 63 (where 32 to 44 are CB preambles);

[0548] When Nr>1, the maximum number of preamble parameters must be an integer multiple of Nr so that it can be divided evenly.

[0549] In addition, when Nr < 1, that is, when one SSB corresponds to multiple RACH occasions (Occasion), the correspondence between the SSB index and the preamble in RACH is in the following order:

[0550] 1. The preambles in each PRACH Occasion are incremented in order of preamble index;

[0551] 2. When RACH frequency division multiplexing (FDM) is configured (i.e., multiple RACH Occasions in the frequency domain), the frequency domain index is incremented.

[0552] 3. When there are multiple PRACH Occasions in a configured PRACH time slot, the index in the PRACH time slot is incremented;

[0553] 4 When multiple PRACH time slots are configured, the PRACH time slot index is incremented.

[0554] For example, corresponding relationship 2:

[0555] If Nsa represents the mapping relationship between SSB (and / or SSB set) and sub-area SArea (Sub-Area).

[0556] If Nsa<1, it means that an SSB (and / or an SSB set) is mapped to multiple sub-areas SArea. For example, if Nsa=1 / 8, then Nsa=1 / 8, which means that an SSB (and / or an SSB set) is mapped to 8 sub-areas SArea, and each sub-area SArea shares the identifier of an SSB (and / or an SSB set). Optionally, the sub-areas associated with an SSB (and / or an SSB set) stagger the transmission and / or reception of the corresponding same SSB (and / or an SSB set) by at least one of the time domain, frequency domain, spatial domain, and code domain.

[0557] In addition, multiple sub-areas SArea can form a sub-area group, and then further determine the sub-area where the UE is located through the correspondence between at least one of the CSI-RS, TCI state, QCL, SRS, random access resources, Mapped Cell ID (mapped cell identifier), and uplink resource information corresponding to different sub-areas. Further, the second communication device can send the first beam and / or the second beam with a period of T2 through the information of the determined sub-area.

[0558] If Nsa>=1, it means that multiple SSBs (and / or multiple SSB sets) are mapped to one sub-area SArea. For example, if Nsa=8, then Nsa=8, which means that 8 SSBs (and / or 8 SSB sets) are mapped to one sub-area SArea.

[0559] Nsa=1, indicating that one SSB is mapped to one sub-area SArea.

[0560] For example, corresponding relationship three:

[0561] If Nsa represents the mapping relationship between an SSB (and / or an SSB set) and a sub-area group SArea-G (Sub-Area Group), multiple sub-areas SArea can form a sub-area group.

[0562] A sub-area group can also be called a sub-area set or a sub-area list.

[0563] If Nsa<1, it means that one SSB (and / or one SSB set) is mapped to multiple sub-area groups SArea-G. For example, if Nsa=1 / 8, then Nsa=1 / 8, which means that one SSB (and / or one SSB set) is mapped to 8 sub-areas SArea-G, and each sub-area SArea-G shares the identifier of one SSB (and / or one SSB set). Optionally, the sub-area groups associated with one SSB (and / or one SSB set) stagger the transmission and / or reception of the same SSB (and / or one SSB set) by at least one of the time domain, frequency domain, spatial domain, and code domain.

[0564] The sub-area where the UE is located is then determined based on a correspondence between at least one of the CSI-RS, TCI state, QCL, SRS, random access resource, mapped cell ID, and uplink resource information corresponding to different sub-areas and / or sub-area groups. Furthermore, the second communication device may send the first beam and / or the second beam with a period of T2 based on the information of the determined sub-area.

[0565] If Nsa>=1, it means that multiple SSBs (and / or multiple SSB sets) are mapped to one or more sub-area groups SArea-G. For example, if Nsa=8, then Nsa=8, which means that 8 SSBs (and / or 8 SSB sets) are mapped to one or more sub-area groups SArea-G.

[0566] Nsa=1, indicating that one SSB is mapped to multiple sub-area groups SArea-G.

[0567] For example, corresponding relationship four:

[0568] If Nar represents a mapping relationship between a sub-region (and / or a sub-region group) and a RO, the preamble corresponding to one of the ROs is specified by the parameter Nap.

[0569] If Nar < 1, it means that a sub-region (and / or sub-region group) is mapped to multiple ROs, and each RO has Nap consecutive preamble indices (0 to Nap-1). For example, if the maximum number of preambles is 64, Nar = 1 / 8, and Nap = 12, then Nar = 1 / 8, which means that one SSB is mapped to 8 ROs, and each RO has 12 consecutive preambles.

[0570] If Nar>=1, one RO is mapped to multiple SSBs. SSBn has Nap consecutive RA preambles, and the starting preamble index of each RO is n*N_total_preamble / Nar.

[0571] Nar=1, indicating that one sub-region (and / or sub-region group) is mapped to one RO.

[0572] If the maximum number of preambles is 64, Nar = 2, and Nap = 12, then if Nar = 2, it means that 2 sub-regions (and / or sub-region groups) are mapped to one RO (64 preambles), and each sub-region (and / or sub-region group) is allocated 32 preambles;

[0573] Starting preamble index of sub-area (and / or sub-area group) 0 = 0*64 / 2 = 0 preamble 0 to 31 (where 0 to 11 are CB preambles);

[0574] Starting preamble index of sub-area (and / or sub-area group) 1 = 1*64 / 2 = 32 preambles 32 to 63 (where 32 to 44 are CB preambles);

[0575] When Nar>1, the maximum number of preamble parameters must be an integer multiple of Nar so that it can be divided evenly.

[0576] In addition, optionally, when Nar<1, that is, when one sub-area (and / or sub-area group) corresponds to multiple RACH Occasions, the correspondence between the sub-area (and / or sub-area group) index and the preamble in the RACH is in the following order:

[0577] 1. The preambles in each PRACH Occasion are incremented in order of preamble index;

[0578] 2. When RACH FDM is configured (i.e., multiple RACH Occasions in the frequency domain), the frequency domain index is incremented;

[0579] 3. When there are multiple PRACH Occasions in a configured PRACH time slot, the index in the PRACH time slot is incremented;

[0580] 4 When multiple PRACH time slots are configured, the PRACH time slot index is incremented.

[0581] For example, corresponding relationship five:

[0582] If NaP represents the mapping relationship between sub-regions and / or sub-region groups and preambles.

[0583] If NaP < 1, it means that a sub-area (and / or a sub-area group) is mapped to multiple preambles. RO resources are not differentiated within the entire cell area. For example, if NaP = 1 / 8, then NaP = 1 / 8 means that a sub-area and / or a sub-area group is mapped to 8 preambles.

[0584] If NaP>=1, a preamble is mapped to multiple sub-areas and / or a sub-area group.

[0585] NaP=1, indicating that a preamble is mapped to a sub-region and / or a sub-region group.

[0586] The above-mentioned various corresponding relationships can also be used in combination.

[0587] According to the above correspondence, the second communication device determines the sub-area of ​​the UE according to the random access information sent by the UE;

[0588] Specifically, according to at least one of the above-mentioned correspondences, at least one of the following methods may be used to determine the beam for sending downlink signaling and / or data, including at least one of the beam type, beam width, beam antenna configuration, beam weight, beam coverage, and beam signal configuration, as follows:

[0589] (a) The second communication device may determine the beam to be sent by the downlink RAR based on the resource location of the UE sending the preamble and / or the RO sending the preamble;

[0590] (b) The second communication device may determine the beam to be sent by MSG4 based on the resource information and / or the content of Msg3 sent by the UE;

[0591] From the UE's perspective:

[0592] According to at least one of the above-mentioned corresponding relationships, at least one of the following methods may be used to determine the beam for downlink signaling and / or data transmission, including at least one of the beam type, beam width, beam antenna configuration, beam weight, beam coverage, and beam signal configuration, as follows:

[0593] (a) The UE can infer the beam sent by the downlink RAR based on the resource location of the UE sending the preamble and / or the RO sending the preamble;

[0594] (a) The UE can infer the beam sent by MSG4 based on the resource information and / or content of Msg3 sent by the UE;

[0595] The beam type includes whether it is the first beam or the second beam; if it is the first beam, whether to use the first SSB and / or the second SSB. In other words, whether to select the first SSB or the second SSB, or the first SSB and the second SSB at the same time.

[0596] Then, the second communication device transmits the first beam of the second SSB marker according to the sub-area information corresponding to the signaling and / or data fed back by at least one UE. The second SSB may be transmitted non-periodically and / or non-uniformly.

[0597] For example, if the sub-area information corresponding to the feedback signaling and / or data of at least one UE shows that the UE locations are unevenly distributed; that is, the UE density in each sub-area is different, the arrival time and / or number of UE services, and / or the degree of link attenuation are different, then the second SSB is selected.

[0598] In this way, the second SSB can be reasonably sent according to the distribution of UEs and / or the service distribution of UEs.

[0599] Optionally, the number of SSBs in each cycle of the SSB may be different and / or the same; in this way, the SSBs may be reasonably sent within each cycle by the base station according to the distribution of UEs and / or the service distribution of UEs;

[0600] Optionally, the index and / or other information of the SSB sent within each cycle of the SSB may be different and / or the same; in this way, the SSB can be effectively and reliably sent within each cycle by the base station based on information such as UE distribution and / or UE service distribution, and channel quality;

[0601] On the other hand, the second communication device may also determine the transmission of a downlink dedicated beam according to the sub-area where the UE's feedback signaling and / or data is located, where the downlink dedicated beam is represented by TCI state and / or QCL. The downlink dedicated beam refers to a beam carrying a CSI-RS and / or UE-specific DM-RS signal. The uplink dedicated beam is represented by spatial relation info.

[0602] Method 2: The second communication device first sends a first beam represented by a first SSB with an SSB transmission period of a first period (e.g., period T1). The first SSB is sent according to the first period (e.g., period T1). Optionally, the binding relationship between each sub-area and CSI-RS, or the corresponding relationship between SSB and PRACH, is configured in the system message; then the second communication device determines the sub-area of ​​the UE based on the PRACH information sent by the UE;

[0603] Specifically, regarding the correspondence between SSB and PRACH, the UE has the opportunity to send a PRACH random access signal only when the SSB beam scanning signal covers and / or illuminates the UE. That is, the PRACH transmission time (RO) needs to be mapped to the SSB index. The second communication device can then determine the downlink RAR transmission beam based on the UE's uplink PRACH resource location, including at least one of the beam type, beam width, beam antenna configuration, beam weight, beam coverage, and beam signal configuration.

[0604] The beam type includes whether it is the first beam or the second beam; if it is the first beam, whether to use the first SSB and / or the second SSB. In other words, whether to select the first SSB or the second SSB, or the first SSB and the second SSB at the same time.

[0605] Then, the second communication device sends the first beam of the second period (eg, period T2) according to the sub-area information corresponding to the signaling and / or data fed back by at least one UE.

[0606] For example, if the sub-area information corresponding to the signaling and / or data fed back by at least one UE shows that the locations of the UEs are relatively evenly distributed and relatively concentrated, then T2 <T1;

[0607] If the sub-area information corresponding to the signaling and / or data fed back by at least one UE shows that the locations of the UEs are relatively evenly distributed and dispersed, then T2>T1;

[0608] On the other hand, the second communication device may also determine the transmission of a dedicated beam based on the sub-area where the UE's feedback signaling and / or data is located, where the downlink dedicated beam is represented by TCI state and / or QCL. The downlink dedicated beam refers to a beam carrying a CSI-RS and / or UE-specific DM-RS signal. The uplink dedicated beam is represented by spatial relation info.

[0609] Method 3: The second communication device simultaneously transmits a first beam represented by a first SSB and a second beam represented by a second SSB. The first SSB is transmitted periodically. The second SSB may be transmitted aperiodically and / or non-uniformly.

[0610] Optionally, a binding relationship between each sub-area and CSI-RS, or a correspondence between SSB and PRACH, is configured in the system message; then the second communication device determines the sub-area of ​​the UE based on the PRACH information sent by the UE;

[0611] Specifically, regarding the correspondence between SSB and PRACH, the UE has the opportunity to send PRACH random access only when the SSB beam scanning signal covers and / or illuminates the UE. That is, the PRACH transmission time RO needs to be mapped to the SSB index.

[0612] The second communication device can then determine the beam to be sent in the downlink random access response (Random Access Response, RAR) based on the resource location of the UE uplink PRACH, including at least one of the beam type, beam width, beam antenna configuration, beam weight, beam coverage, and beam signal configuration.

[0613] The beam type includes whether it is the first beam or the second beam; if it is the first beam, whether to use the first SSB and / or the second SSB. In other words, whether to select the first SSB or the second SSB, or the first SSB and the second SSB at the same time.

[0614] The second communication device then transmits the first beam of the second SSB marker based on the sub-area information corresponding to the signaling and / or data fed back by the at least one UE. For example, if the sub-area information corresponding to the signaling and / or data fed back by the at least one UE indicates that the UEs are unevenly distributed; that is, the UE density in each sub-area is different, and the arrival time and / or arrival amount of UE services, and / or the link attenuation level are different, then the second SSB is selected.

[0615] In this way, the second SSB can be sent reasonably according to the distribution of UEs and / or the service distribution of UEs;

[0616] The number of SSBs in each cycle of the SSB may also be different and / or the same; in this way, the SSBs may be sent reasonably within each cycle according to the distribution of UEs and / or the service distribution of UEs;

[0617] The index and / or other information of the SSB sent within each cycle of the SSB may be different and / or the same; thus, the SSB can be effectively and reliably sent within each cycle based on the distribution of UEs and / or the distribution of UE services, as well as information such as channel quality;

[0618] On the other hand, the second communication device may also determine the transmission of a dedicated beam based on the sub-area where the UE's feedback signaling and / or data is located, where the downlink dedicated beam is represented by TCI state and / or QCL. The downlink dedicated beam refers to a beam carrying a CSI-RS and / or UE-specific DM-RS signal. The uplink dedicated beam is represented by spatial relation info.

[0619] Optionally, the UE receives at least one DRX and / or DRX format information sent by the second communication device; the format information is sent in at least one of the following ways: with a cell as a granularity; with a beam as a granularity; with a sub-area as a granularity; with a sub-area group as a granularity; with a first communication device as a granularity; with a service of the first communication device as a granularity; with a beam type as a granularity;

[0620] The type of the beam is at least one of a first beam, a second beam, a first beam with a period of T1, and a second beam with a period of T2.

[0621] Referring to FIG9 , the specific steps include:

[0622] Step 1: The UE is located in sub-area 2 of sub-area group 8;

[0623] For the relationship between sub-region groups and sub-regions, please refer to FIG8 .

[0624] Step 2: The UE receives information such as the SSB of the first beam (with a period of T1). For example, the first beam may cover all beams of sub-region group 8, or beams 1-6 (sub-regions 1-6) of sub-region group 8.

[0625] Step 3: The UE sends a preamble and / or sends UL data and / or signaling on the uplink resources indicated by the uplink resource information according to the correspondence between at least two of the SSB, TCI state, QCL, CSI-RS, SRS, random access resources, low power signal, Mapped Cell ID, sub-area and / or sub-area group of the second communication device, and uplink resource information, for example, at least one of the random access resources, TCI state, QCL, CSI-RS, and SRS corresponding to beams 1-6 of sub-area group 8.

[0626] Step 4: The second communication device determines that the sub-area and / or sub-area group where the UE is located corresponds to sub-area 1-6 of sub-area group 8 based on the UE sending the preamble code and / or sending the UL data and / or signaling on the uplink resources indicated by the uplink resource information, as well as the above correspondence.

[0627] After step 4, at least one of step 5-1, step 6-1, step 7-1, step 8-1, and step 9-1 may be performed.

[0628] Step 5-1: The second communication device still sends the first beam with a period of T1, and data and / or signaling, for example, at least one of MSGB, RAR, and DCI, is sent on the first beam;

[0629] Step 5-2: The UE sends MSG3 and / or data on the UL resources indicated in the RAR and / or DCI;

[0630] Step 5-3 (optional): The second communication device indicates the second beam information in the DCI;

[0631] Step 5-4: The UE receives and / or sends data and / or signaling on the second beam, such as MSG4 / MSG5.

[0632] Step 6-1: The second communication device still sends the first beam with a period of T1;

[0633] Step 6-2: Data and / or signaling, such as at least one of MSGB, RAR, and DCI, is sent on the original first beam, and the RAR and / or DCI indicate the first beam with a period of T2 or the first beam corresponding to the second SSB.

[0634] Step 6-3: The UE sends MSG3 and / or data on the UL resources corresponding to the first beam with a period of T2 or the first beam of the second SSB indicated in the RAR or / and DCI, and receives and / or sends data and / or signaling, such as MSG4 / MSG5, on the first beam with a period of T2.

[0635] Step 6-4 (optional): The second communication device indicates the second beam information in the DCI;

[0636] Step 6-5: The UE receives and / or sends data and / or signaling on the second beam, such as MSG4 / MSG5;

[0637] Step 7-1: The second communication device sends a first beam with a period of T2 in the sub-area and / or sub-area group where the UE is located;

[0638] Step 7-2: Data and / or signaling, such as at least one of MSGB, RAR, and DCI, is sent on the first beam with a period of T2, and the RAR and / or DCI indicates information about the second beam;

[0639] Step 7-3: The UE sends MSG3 and / or data on the UL resources corresponding to the second beam indicated in the RAR or / and DCI, and receives and / or sends data and / or signaling on the second beam, such as MSG4 / MSG5.

[0640] Step 7-4 (optional): The second communications device indicates second beam information in a DCI;

[0641] Step 7-5: The UE receives and / or sends data and / or signaling on the second beam, such as MSG4 / MSG5;

[0642] Step 8-1: The second communication device sends a first beam corresponding to a second SSB in the sub-area and / or sub-area group where the UE is located;

[0643] Step 8-2: Data and / or signaling, such as at least one of MSGB, RAR, and DCI, are sent on the first beam corresponding to the second SSB, and information indicating the second beam in the RAR and / or DCI is sent.

[0644] Step 8-3: The UE sends MSG3 and / or data on the UL resources corresponding to the second beam indicated in the RAR or / and DCI, and receives and / or sends data and / or signaling on the second beam, such as MSG4 / MSG5.

[0645] Step 8-4 (optional): The second communications device indicates second beam information in a DCI;

[0646] Step 8-5: The UE receives and / or sends data and / or signaling on the second beam, such as MSG4 / MSG5;

[0647] Step 9-1: The second communication device sends a second beam in the sub-area and / or sub-area group where the UE is located;

[0648] Step 9-2: Data and / or signaling, such as at least one of MSGB, RAR, and DCI, are sent on the second beam;

[0649] Step 9-3 (optional): The second communication device indicates second beam information in the DCI;

[0650] Step 9-4: The UE receives and / or sends data and / or signaling on the second beam, such as MSG4 / MSG5.

[0651] (2) About time domain characteristics

[0652] The maximum number of packets sent in an SSB cycle is L = 4 / 8 / 64;

[0653] The index of each SSB ranges from 0 to L-1. The UE needs to obtain the current SSB index information from the PBCH block to obtain the complete downlink timing of the air interface:

[0654] (a) For L=4, 2 bits are used to represent the SSB block index;

[0655] (b) For L=6, 3 bits are used to represent the SSB block index;

[0656] (c) For L=8, 6 bits are used to represent the SSB block index. The SSB block index can only be obtained after the UE demodulates the PBCH.

[0657] (3) Remaining Minimum System Information (RMSI) (SIB1).

[0658] After obtaining the SSB, the UE needs to obtain some essential system information (SIBs) because the Master Information Block (MIB) is limited and insufficient for camping on the cell and initiating initial access. To ensure the fastest synchronization and access possible, the necessary system information is divided into two parts: the MIB and SIB1. For the secondary communication device cell, SIB19 is also included. Other non-essential information is retrieved when needed. SIB1 provides information such as the uplink frequency (UL freq) and time division duplex configuration (TDD cfg).

[0659] SIB information in NR is transmitted via the Physical Downlink Shared Channel (PDSCH), which requires the DCI of the PDCCH to schedule. Therefore, the UE needs to obtain the PDCCH channel information for scheduling SIB1 from the MIB and perform blind detection on the Physical Downlink Control Channel (PDCCH) to obtain SIB1. The pdcch-ConfigSIB1 field in the MIB allows the UE to obtain PDCCH information for RMSI scheduling.

[0660] (4) Control resource set 0 (Control REsource SET CORESET 0, CORESET0);

[0661] During the downlink synchronization process of NR, the UE must first blindly detect the SSB, then find the corresponding CORESET0 based on the SSB, and then blindly detect the PDCCH in CORESET0, and then obtain the DCI, so as to find the PDSCH carrying SIB1.

[0662] The PDCCH channel in NR has multiple search spaces, including: common search space and UE-specific search space.

[0663] Among them, Type 0 Common Search Space (Type 0CSS) is only used for RMSI scheduling;

[0664] The Control-Resource Set (CORESET) is introduced in NR, which is the definition of the configuration of the PDCCH channel in the physical resource set. A cell PDCCH channel can have multiple control resource sets, and each control resource set has an ID.

[0665] CORESET0 is the physical resource set corresponding to Type 0 Common Search Space (RMSI).

[0666] (5) About pdcch-ConfigSIB1 in MIB.

[0667] CORESET 0 is configured by the MIB. The upper 4-bit index table query can be used to determine the number of consecutive resource blocks (RBs) occupied by CORESET 0 in the frequency domain, the number of consecutive symbols occupied in the time domain, the type of multiplexing between CORESET 0 and SSB, and the offset. The lower 4-bit index table query can be used to determine the corresponding PDCCH monitoring timing.

[0668] The retrieval table corresponding to the upper 4 bits has a total of 10 retrieval tables according to the subcarrier spacing between SSB and PDCCH and the minimum channel bandwidth of the system. According to the data in the table, it can be known that the multiplexing type of CORESET0 and SSB is type 1. CORESET 0 occupies 24 RBs in the frequency domain and 2 symbol lengths in the time domain, with an offset of 0 RB.

[0669] In the terrestrial network, SIB1 and SSB must be on the same beam, but the time-frequency domain resources are different. However, in the second communication device cell, due to the limited number of beams, the pdcch-ConfigSIB1 in the MIB can optionally indicate at least one of the following information: (a) beam information of SIB1, (b) waiting time of SIB1, (c) the interval between the start time of SSB and the start time of SIB1, (d) the absolute time of arrival of SIB1 information, (e) the associated epoch time, and (f) the associated reference time.

[0670] Optionally, when the UE finishes sending data, an end of data (burst) indication is sent to the second communication device, and then the second communication device temporarily stops sending a dedicated beam to the UE, and / or uses a large-period SSB sending interval in this sub-area.

[0671] The UE can inform the radio access network of at least one piece of information, such as the amount of UE buffered data and the rate, through at least one of periodic transmission, event triggering, and higher-layer information indication via a Buffer Status Report (BSR) or other signaling, such as uplink control information (UTO-UCI) carrying unused transmission opportunities (TOs) and / or UE Assistance Information (UAI). This information can assist the radio access network in beam selection, including information such as the beam bandwidth, beam angle, beam transmit power, beam DM-RS configuration, number of antenna ports, and antenna panel.

[0672] Optionally, the second communication device informs the UE of at least one of the subsequent beam arrival time and duration information.

[0673] Optionally, the sub-area may refer to a wave position, at least one concept in a region, and the sub-area is associated with at least one parameter of SSB index, geographic range, CSI-RS, random access preamble (RACH preamble), RO, and DM-RS.

[0674] Optionally, the format (pattern) of the SSB may be aperiodic; in this way, the SSB may be sent appropriately based on the distribution of UEs and / or the service distribution of UEs;

[0675] Optionally, the number of SSBs in each cycle of the SSB may be different and / or the same; in this way, the SSBs may be reasonably sent within each cycle according to the distribution of UEs and / or the service distribution of UEs;

[0676] Optionally, the index and / or other information of the SSB sent within each cycle of the SSB may be different and / or the same; in this way, the SSB can be effectively and reliably sent within each cycle based on the distribution of UEs and / or the service distribution of UEs, as well as information such as channel quality;

[0677] Optionally, the association relationship between the beam carrying SSB and the beam carrying CSI can be sent to the UE; wherein the association relationship between the beam carrying SSB and the beam carrying CSI includes specific time correspondence information and / or sub-area information.

[0678] Optionally, if UE1 receives paging on the beam carrying SSB, UE1 initiates a random access process on the beam, and the second communication device sends a dedicated beam to UE1 after receiving the preamble.

[0679] Optionally, when the SSB sends a dedicated beam to UE1, the SSB is not sent, but the tracking reference signal (tracking RS) is still sent.

[0680] Optionally, the second communication device may update the pattern through signaling of Medium Access Control (MAC) or Downlink Control Information (DCI).

[0681] One way is to add the following content in SIB19:

[0682] (a) The period of SSB transmission is bound to the epoch time and / or reference time;

[0683] (b) Matching relationship between SSB and RO, non-periodic configuration.

[0684] (c) Sub-area binding sent by SSB in PATTERN;

[0685] Special paging is used to notify the SSB transmission sub-area and the UE-specific beam transmission information. The specific information includes at least one of the transmission sub-area, pattern, and period.

[0686] Optionally, RRC is configured with a semi-static pattern format;

[0687] The pattern is then updated through MAC or DCI signaling. The second communication device determines the transmission of N2 and / or N3 based on the density and sub-area of ​​the UE.

[0688] If not bound to a sub-area, similar to the SSB mechanism, the UE determines its own pattern sub-area, SSB index, or CSI-RS index by detecting the SSB.

[0689] If UE1 receives paging at N2, UE1 initiates a random access process at N2, and the second communication device sends a beam of N3 to UE1 after receiving the preamble.
