[0074] Due to the distance between the satellite and the Earth's surface, as well as the satellite's rapid movement, long propagation distances / delays and / or large Doppler shifts can be problems for satellite communication systems. In conjunction with satellite communications supported by 5G NR, large timing advances (TAs) will be implemented, and a corresponding parameter, Koffset, will be introduced to maintain timing relationships involving DL-UL timing interactions.

[0075] Regarding information about broadcast systems, networks (e.g., Figure 2 In BS204, the synchronization signal block (SSB) is broadcast in the cell, which includes and / or indicates synchronization signal and / or master information block (MIB) information. The UE (e.g., Figure 2 UE 204 can synchronize with the network on the downlink by detecting SSB and / or acquiring (e.g., obtaining, collecting) information in MIB (e.g., basic configuration information in the cell, system frame number (SFN), subcarrier spacing (SCS), SSB index and / or frequency information, etc.).

[0076] The MIB may also include control information regarding subsequent SIB 1 broadcasts. This allows the UE to decode (e.g., decipher, crack) the SIB 1 information with the help of the control information in the MIB. SIB 1 may include common configurations regarding RACH, physical channels, and / or paging channels.

[0077] When a BS schedules a UL transfer, the scheduling offset is configured to indicate the available time-domain UL resources for the UL transfer (e.g., in an FDD system). For example, Figure 1 This is a block diagram depicting an example environment 100 of timing advance (TA) in an NR according to an embodiment of the present disclosure. Environment 100 includes frame 102 (in Figure 1 (shown as "gNB DL"), frame 102 can be obtained from the BS (e.g., Figure 2 BS202) is transmitted to UE (e.g., Figure 2 UE 204) and contains multiple time slots, wherein the first time slot of the multiple time slots (e.g., in chronological order) is identified as time slot 103 (in Figure 1 (shown as "n"), while the final time slot is identified as time slot 109 (in Figure 1 (shown as "m" in the text). Environment 100 includes frame 104 (in... Figure 1 (Shown as "UE DL"), frame 104 can be received by the UE from the BS and contains multiple time slots, wherein the first time slot of the multiple time slots (e.g., in chronological order) is identified as time slot 105 (in Figure 1 (shown as "n"), while the last time slot is identified as time slot 110 (in Figure 1 (shown as "m" in the text).

[0078] Environment 100 includes frame 106 (in Figure 1 (shown as "UE UL"), frame 106 can be transmitted from the UE to the BS and contains multiple time slots, wherein the first time slot of the multiple time slots (e.g., in chronological order) is identified as time slot 107 (in Figure 1 (shown as "n"), while the last time slot is identified as time slot 111 (in Figure 1 (shown as "m" in the text). Environment 100 includes frame 108 ( Figure 1 (shown as "gNB DL"), frame 108 can be received by the BS from the UE and contains multiple time slots, wherein the first time slot of the multiple time slots (e.g., in chronological order) is identified as time slot 109 (in Figure 1 (shown as "n"), while the last time slot is identified as time slot 112 (in Figure 1 (shown as "m" in the text).

[0079] Specifically, frame 102 shows the transmission of the "first" frame from the BS, and frame 104 shows the UE's reception of the "first" frame. Frame 106 shows the transmission of the "second" frame from the UE, and frame 108 shows the BS's reception of the "second" frame. Figure 1 As shown, delay 110 indicates the time delay between the BS's transmission of the "first frame" (measured at the beginning of time slot 103 of frame 102) and the UE's reception of the "first" frame (measured at the beginning of time slot 105 of frame 104). Delay 112 indicates the time delay between the UE's transmission of the "second frame" (measured at the beginning of time slot 107 of frame 106) and the BS's reception of the "second" frame (measured at the beginning of time slot 109 of frame 108). TA 114 indicates the time delay between the UE's transmission of the "second frame" (measured at the beginning of time slot 107 of frame 106) and the UE's reception of the "first" frame (measured at the beginning of time slot 105 of frame 104). There is an offset (e.g., a scheduling offset) between the beginning of time slot 103 and the beginning of time slot 109. The scheduling offset indicates the time-domain offset between the start of the first resource (time slot 103) used by the wireless communication node for downlink transmission and the start of the second resource (time slot 109) used by the wireless communication device for uplink transmission.

[0080] In some embodiments, the process can be as follows: gNB DL (transmitting scheduling information on the gNB side) to UE DL (receiving scheduling information on the UE side) to UE UL (transmitting UL transmission on the UE side) to gNB UL (receiving UL transmission on the gNB side).

[0081] In some embodiments, a basic requirement may be that the UL transmission time (e.g., time slot m of frame 106) cannot be earlier than the received scheduling time (e.g., time slot n of frame 104).

[0082] However, a technical problem is that if the offset is configured to be very large, additional latency may be introduced even if the requirements can be met. Conversely, if the offset is not large enough, the timing relationships involved in DL-UL timing interactions may not hold (e.g., from the UE side). For example, considering a scenario where the UE is served by satellite, if a cell-specific offset is configured and / or broadcast to all UEs, a maximum value or even larger could be used. In this case, communication between one or more UEs, the BS, and / or the satellite is affected by latency issues. Furthermore, if each UE is configured with a UE-specific value, large signaling overhead can negatively impact network performance.

[0083] Therefore, the systems and methods discussed in this paper address the aforementioned technical problems by using one or more values ​​of the SIB-configured scheduling offset (sometimes referred to as "Koffset") to produce appropriate scheduling delay effects and / or acceptable signaling overhead.

According to various embodiments of this solution, such communication nodes can be capable of wireless and / or wired communication.

[0099] 2.1 Group 1: General Structure

[0100] In some embodiments, BS (e.g., Figure 2In some embodiments, the BS (BS202) broadcasts an SSB to the UE in the cell, and also broadcasts an SIB including a scheduling offset value. In some embodiments, the BS broadcasts an SSB to the UE in the cell, and also broadcasts an SIB 1 including multiple Koffset values. In some embodiments, the BS broadcasts an SSB to the UE in the cell, and also broadcasts an SIB x (x>=1) including a Koffset value. In some embodiments, the BS broadcasts an SSB to the UE in the cell, and also broadcasts an SIB x (x>=1) including satellite status information or timestamp information. In some embodiments, the satellite status information includes at least one of the following: the satellite's position, or the satellite's ephemeris.

[0101] In some embodiments, some (e.g., one or more) or all UEs in a cell receive (e.g., retrieve, acquire) SIB 1, which includes multiple Koffset values. In some embodiments, the BS may indicate the Koffset for a target UE.

[0102] In some embodiments, the value of Koffset is configured and / or associated with a beam. In some embodiments, the UE only decodes the Koffset (multiplexing for different beams) in the received SIB x. In some embodiments, the BS may indicate the beam used for the target UE.

[0103] 2.2 Group 2: Beam Correlation Method

[0104] By instructing the target UE (e.g., Figure 2 Regarding the question of which Koffset UE 204 is used on, this disclosure provides a technical solution to the technical problem of Group 2.

[0105] Figure 4 This is a flowchart depicting an example operating process according to an embodiment of the present disclosure. The operating process illustrates a UE (e.g., Figure 2 UE 204) and BS (e.g., Figure 2 Communication between UE 202 in the system. In some embodiments, the BS transmits a first message to the UE (in Figure 4 (Shown as "SSB#0, SSB#1"). In some embodiments, the BS transmits a second message to the UE (in... Figure 4 (Shown as "SSB#0, SSB#1"). In some embodiments, the BS transmits a third message to the UE (in... Figure 4 (Shown as "Other SIB x"). In some embodiments, the BS receives a fourth message from the UE (in... Figure 4 (Shown as "preamble"). In some embodiments, the BS transmits a fifth message to the UE (in...). Figure 4(Shown as "Message 2"). In some embodiments, the BS receives a sixth message from the UE (in... Figure 4 (Illustrated as "Message 3"). In some embodiments, the BS transmits a seventh message to the UE (in... Figure 4 (Shown as "Message 4"). In some embodiments, the BS transmits an eighth message to the UE (in... Figure 4 (Shown as "Schedule").

[0106] Figure 5 This is a flowchart depicting an example process for instructing Koffset according to embodiments of this disclosure. The flowchart illustrates a UE (e.g., Figure 2 UE 204) and BS (e.g., Figure 2 Communication between UE 202). For example... Figure 5 As shown, the UE can detect (e.g., determine, identify) the Koffset used for receiving the beam in the default manner based on the association (e.g., relationship) between the SSB and Koffset.

[0107] As described below, the BS and / or UE can define and / or adjust the association between at least two of the SSB, transmit beam, and Koffset.

[0108] Figure 6 This is a block diagram depicting an example association between a Koffset and an SSB according to embodiments of the present disclosure. In some embodiments, the BS and / or UE may define the association (e.g., relationship) between the Koffset and the SSB. In some embodiments, the BS and / or UE may define the association between the Koffset and the SSB, and the virtual beam. In some embodiments, the BS and / or UE may define the association between the Koffset and the TCI. In some embodiments, the association between the Koffset and the SSB may be related to the transmit beam and / or the receive beam.

[0109] In some embodiments, according to at least one of the three instances, beam indication may be associated with (e.g., correlated with) Koffset indication and / or subsequent reception as a transmission of PDCCH / PDSCH.

[0110] In the “first” instance (sometimes referred to as the “default method”), there is no beam indication for the target UE. In some embodiments, in the first instance, an association is assumed to be established.

[0111] From the perspective of the target UE, the SSB is broadcast (e.g., transmitted) in the corresponding transmission beam. Furthermore, according to the default method, subsequent transmissions and / or receptions for the target UE (e.g., PDCCH / PDSCH) can be assumed to use the same spatial filter as the SSB. In some embodiments, the Koffset associated with a specific SSB is acquired (e.g., obtained, retrieved) by the target UE.

[0112] In the "second" instance, Koffset can be indicated via TCI. For example, Figure 7 This is a flowchart depicting an example process for indicating Koffset according to embodiments of the present disclosure. In some embodiments, the TCI state indication is based on a signal notification (e.g., transmission) of a specific beam, which indicates which beam is used by the target UE. In some embodiments, the TCI state includes information about a reference signal (e.g., CSI-RS or SSB). In some embodiments, the CSI-RS or SSB may identify (e.g., determine, detect) the precise beam.

[0113] In some embodiments, transmissions / receptions (e.g., PDCCH / PDSCH) for a target UE are associated with a specific TCI, and / or the network informs the device that it may assume that the transmission is performed using the same spatial filter indicated by the SSB via the TCI.

[0114] In some embodiments, it is assumed that the above association is established, and the association between Koffset and TCI indication can be used to indicate Koffset.

[0115] Figure 8 This is a block diagram depicting example associations between the TCI state index, virtual beam index, Koffset index, and SSB index according to embodiments of the present disclosure. In some embodiments, the BS and / or UE may define associations (e.g., relationships) between the TCI state index, virtual beam index, Koffset index, and / or SSB index. In some embodiments, the BS and / or UE may define associations (e.g., relationships) between the TCI state index and the Koffset index.

[0116] In the "third" instance, Koffset can be implicitly indicated. In some embodiments, auxiliary information is broadcast from the BS. In some implementations, the UE can identify (e.g., determine) the beam used based on the auxiliary information. In some embodiments, this information may include reference point information corresponding to each beam. In some embodiments, this information may include BWP information corresponding to each beam.

[0117] In some embodiments, an association is assumed to be established, and the association between Koffset and the transmission beam and / or beam indicator (implicitly) is utilized, so that Koffset can be indicated.

[0118] 2.2.1 Implementation of the (multiple) embodiments of Group 2

[0119] In the “first” instance (sometimes referred to as “case 2”), the implementation is based on an SSB-based solution in the initial state. The BS broadcasts an SSB to one or more UEs in the cell, and / or broadcasts an SIB 1 comprising multiple Koffset values.

[0120] In some embodiments, it is assumed that an association is established between at least two of the SSB, the transport beam, and the Koffset. For example, from the UE's perspective, the SSB is broadcast from the network and configured with a corresponding Koffset. The UE can obtain (e.g., retrieve, obtain) the Koffset based on the association between the SSB and the Koffset using a default method.

[0121] In some embodiments, the SSB is indicated by the TCI, and / or the corresponding Koffset is indicated.

[0122] In the “second instance” (sometimes referred to as the “BWP-based solution after network access”), when a UE successfully accesses the network, an active BWP is allocated (e.g., configured, dedicated, reserved) for data transmission in each beam. In some embodiments, it is assumed that an FDM BWP can be allocated for each beam. From the network perspective, the corresponding Koffset is configured and / or updated for the BWP required by a connected UE. In this way, a common Koffset is configured and / or updated for UEs within the beam service. Furthermore, the same BWP can be reused in non-adjacent beams, so the maximum value of the Koffset associated with these beams can be configured.

[0123] 2.3 Group 3: Beam Correlation Method

[0124] This disclosure provides a technical solution to the technical problems of Group 3 by designing an indication of the beam / Koffset used by the target UE.

[0125] In the "first" instance (sometimes referred to as the "default method"), beam indication is transparent to the target UE. In some embodiments, the UE receives the beam / radio signal to decode the received SIB x, x>=1, and the value of Koffset in SIB x can be obtained. Meanwhile, in some embodiments, no association is required.

[0126] In the "second" example, beam indication can be indicated via TCI. For example, Figure 9 This is a block diagram depicting an example association between Koffset and TCI according to an embodiment of this disclosure.

[0127] Assuming Koffset is contained in SIBx, x>1, in some embodiments, SIBx for different beams can be multiplexed in time / frequency / space / code domain.

[0128] In some embodiments, transmission / reception for a target UE (e.g., PDCCH / PDSCH) is associated with a certain TCI, and / or the network informs the device (e.g., notifies) that it may assume that the transmission is performed using the same spatial filter as the beam indicated via the TCI.

[0129] Figure 10 This is a block diagram depicting an example association between the TCI state index, the virtual beam index, and the Koffset index according to embodiments of the present disclosure. In some embodiments, the BS and / or UE may define an association (e.g., a relationship) between the TCI state index, the virtual beam index, and the Koffset index. In some embodiments, the BS and / or UE may define an association (e.g., a relationship) between the TCI state index and the Koffset index.

[0130] 2.3.1 Implementation of the (multiple) embodiments of Group 3

[0131] In the “first” instance (sometimes referred to as “case 3-1”), the implementation is achieved by SIB broadcasting and / or a beam-based solution. In some embodiments, the BS broadcasts an SSB to one or more UEs in the cell, and / or broadcasts an SIB 1 including a Koffset value for each beam. In some embodiments, the UE receives the beam / radio signal to decode the received SIB x, x>=1, and the Koffset value in SIB x can be obtained. In some embodiments, the beam is indicated by a TCI, and the corresponding Koffset is indicated.

[0132] In the "second" instance (sometimes referred to as "case 3-2"), the implementation is achieved via multicast. In some embodiments, for connected UEs, the BS group schedules SIBx / or PDSCH for multiple UEs. In some embodiments, the content of the SIBx / or PDSCH may include the common Koffset of the UEs.

[0133] 2.4 Group 4: Group-related methods

[0134] In this embodiment, a common Koffset is assigned to a group of UEs. The UEs in the group may have close locations or similar channel states.

[0135] In the first instance (sometimes referred to as "Case 4-1"), the implementation is achieved through a beam-based solution using SIB broadcasting. In some embodiments, the BS broadcasts an SSB to the UEs in the cell and broadcasts an SIB 1 including the value of Koffset for each group.

[0136] In some embodiments, the UE in the group receives beam / radio signals to decode the received SIB x, x>=1, and the value of Koffset in SIB x can be obtained.

[0137] In some embodiments, the beam is indicated by TCI, and / or the corresponding Koffset is indicated.

[0138] In the second example (sometimes referred to as "Scenario 4-2"), the implementation is carried out by a BWP-based solution after network access. In some embodiments, when the UE successfully accesses the network, an active BWP is allocated for data transmission in each group. In some embodiments, it is assumed that an FDM BWP can be allocated for each group. In some embodiments, from the network perspective, the corresponding Koffset is configured and / or updated for the BWP required by the connected UE. In this way, a common Koffset is configured and / or updated for UEs within the group.

[0139] In the third example (sometimes referred to as "Scenario 4-3"), the implementation is based on multicast. In some embodiments, for connected UEs, the BS group schedules SIBx and / or PDSCH for a group of UEs. In some embodiments, the content of SIBx and / or PDSCH may include a common Koffset for the UEs.

[0140] Group 2.5, Part 5: Updates for each UE after network access.

[0141] In the first instance (sometimes referred to as “Case 5-1”), the implementation is based on an update per UE. In some embodiments, the update may be a new Koffset for each UE, with a dedicated Koffset assigned.

[0142] In some embodiments, updates are based on an adjustment value that indicates a change and / or adjustment to a previous old value. Furthermore, connected UEs can be scheduled and informed via PDCCH, RRC signaling (e.g., msg 4 / msg B), or MAC CE.

[0143] In the second example (sometimes referred to as "Case 5-2"), the implementation is based on updates for each UE, where UEs within a beam share a common Koffset. In this case, a constraint is added compared to Case 5-1: the Koffset value of the beam is a single value, for example, based on a beam center reference point or a beam edge reference point. It is assumed that the BS knows which beam center reference point or beam edge reference point the UE belongs to.

[0144] 2.6 Group 6: Additional Implementation Examples with GNSS Assistance

[0145] In this example, the BS broadcasts an SIB, which includes multiple Koffsets. In some embodiments, it is assumed that the UE itself calculates the common TA with the help of GNSS capabilities. By comparing the calculated common TA with the multiple received Koffsets, the closest Koffset can be adopted using unit conversion.

[0146] In some embodiments, the BS broadcasts an SIB, which includes multiple Koffsets and multiple serving link common TAs. In some embodiments, each Koffset is associated with a serving link common TA. In some embodiments, it is assumed that the UE itself calculates the common TA with the aid of GNSS capabilities by finding an equivalent value to one of the received serving link common TAs, and the corresponding Koffset can be used.

[0147] In some embodiments, for NB-IoT scenarios, the UE procedure for reporting ACK / NACK (Hybrid Automatic Repeat Request Acknowledgment) may be to transmit HARQ-ACK on the PUSCH within time slot n+K1+Koffset; wherein the last repeat of the PDSCH received at the end of time slot n or the SPS PDSCH release via PDCCH, and the last repeat of the PDCCH received at the end of time slot n, where K1 is the number of time slots and is indicated by DCI or by higher layer signaling.

[0148] In some embodiments, for PUR (pre-configured UL resources) scenarios in NB-IoT or LTE-M scenarios, the PUR search space window should be expanded by the value of Koffset.

[0149] In some embodiments, a wireless communication node broadcasts a physical broadcast channel (PBCH) and a system information block, thereby causing a wireless communication device that receives the PBCH and the system information block to determine one of a plurality of scheduling offsets.

[0150] In some embodiments, a wireless communication node broadcasts a system information block in a TDM or FDM resource, thereby causing the wireless communication device that receives the system information block to determine a scheduling offset.

[0151] In some embodiments, a wireless communication node broadcasts a system information block in a narrow frequency band or carrier, thereby causing the wireless communication device that receives the system information block to determine a scheduling offset.

[0152] In some embodiments, a wireless communication node broadcasts a system information block to a wireless communication device, the system information block indicating the configuration of different resources. In some embodiments, the configuration includes at least one of the following: a common value for timing advance, a common value for frequency pre-compensation for downlink. In some embodiments, the different resources include at least one of different BWPs, different narrowbands or carriers, and different virtual beam indices.

[0153] In some embodiments, a wireless communication node broadcasts a system information block to a wireless communication device during an authorized time interval.

[0154] In some embodiments, a wireless communication node broadcasts a system information block to a wireless communication device during a downlink gap.

[0155] For example, Figure 11 An example of a UL gap (e.g., an authorized time gap) inserted after certain consecutive uplink transmissions is shown. The uplink gap may be an authorized time gap between a first transmission and a second transmission, configured according to a configuration from the wireless communication node, wherein the first transmission includes the wireless communication device transmitting multiple first uplink messages to the wireless communication node, and the second transmission includes the wireless communication device transmitting multiple second uplink messages to the wireless communication node. In other embodiments, a default configuration may exist such that the uplink gap is a fixed value. For example, the gap is 40 ms and can be configured to be inserted after a certain time period.

[0156] The downlink gap can be a licensed time interval between a first transmission and a second transmission, configured from the wireless communication node, wherein the first transmission includes the wireless communication device transmitting multiple first downlink messages to the wireless communication node, and the second transmission includes the wireless communication device transmitting multiple second downlink messages to the wireless communication node. In other embodiments, a default configuration may exist such that the downlink gap is a fixed value. For example, the gap is 40 ms and can be configured to be inserted after a certain time period.

[0157] In some embodiments, a UE in an RRC connected state is configured to receive system information during a licensed time gap. In some embodiments, the licensed time gap may be a default configuration, such that the uplink gap or downlink gap is a fixed value. For example, a 40ms gap may be configured to be inserted after a certain period of time. In other embodiments, the licensed time gap may be a dedicated gap. For example, an x ​​ms gap may be configured before transmission or may be configured to be inserted after a certain period of time during continuous transmission, where x is an integer.

[0158] In some embodiments, the system information includes at least one of the following: timestamp, real-time PVT (position, velocity, time) information of the satellite, satellite ephemeris, common values ​​for timing advance, or common values ​​for Doppler shift.

[0159] In some embodiments, the BS configures enable signaling to enable / disable receiving system information within an authorized time slot. For example, enabling the UE to receive SI within the authorized time slot. In some embodiments, the BS configures the reception duration (authorized time slot) for receiving system information during UL transmission, and if the UL transmission conflicts with the reception duration, the UE discards the UL transmission.
