Description

[Technical Field]

[0001] This disclosure claims priority to a Chinese patent application with application number 202110357557.0, filed with the China Intellectual Property Office on April 1, 2021. The entire contents of the above application are incorporated herein by reference.

[0002] The present application relates to the field of wireless communication, for example, to a channel transmission method, an apparatus, a terminal, a base station, and a storage medium. [Background technology]

[0003] In terrestrial networks such as NB-IOT (Narrow Band Internet of Things) and eMTC (Enhanced Machine Type Communication), a PUR function is introduced to pre-configure link resources of the Physical Uplink Shared Channel (PUSCH) for UEs with a fixed service mode, with the aim of saving energy for terminals (UEs). A UE in RRC_IDLE or RRC_INACTIVE state can transmit uplink data directly using the pre-configured PUSCH resources, thereby omitting the access procedure of the Physical Random Access Channel (PRACH), thereby reducing UE power consumption. However, the use of the PUR function presupposes that the UE's Timing Advance (TA) remains constant. The only way to ensure that the UE's TA remains constant is for the UE to be stationary. Therefore, in NB-IOT and eMTC terrestrial networks, the PUR function is only applicable to stationary UEs.

[0004] However, in non-terrestrial networks (NTNs), especially low-earth-orbit satellite wireless networks, satellites move even when the UE is stationary. This means that the cell and satellite may be in a relative moving state, so the cell that sets the PUR resource for the UE may not be the same cell that ultimately performs PUR transmission for the UE, and the UE's TA is constantly changing. Therefore, the PUR function cannot be applied to NTN networks, and there is currently an urgent need to establish a channel communication method based on the PUR function in NTN networks. Summary of the Invention [Problem to be solved by the invention]

[0005] The embodiments of the present application propose a channel transmission method, device, terminal, base station, and storage medium that are intended to realize channel transmission based on the PUR function in a non-terrestrial network, save radio resources, and reduce the power consumption of UEs.

[0018] It is to be understood that the specific embodiments described herein are illustrative of the present application and are not intended to be limiting of the present application.

[0019] In the following description, the suffixes "module," "member," or "unit" used to represent components are used only to facilitate the description of this application and do not have any special meaning in themselves. Therefore, the terms "module," "member," or "unit" may be used interchangeably.

[0020] 1 is a flowchart of a channel transmission method provided by an embodiment of the present application, which is applied to a situation in which PUR transmission is supported in a non-terrestrial network. The method may be implemented by software and / or hardware and is generally integrated into a terminal. The terminal may be in a state without a Radio Resource Control (RRC) connection with a base station, which may include an RRC_IDLE state and an RRC_INACTIVE state. Referring to FIG. 1, the method provided by an embodiment of the present application includes the following steps:

[0021] In step 110, receive pre-configured uplink resource (PUR) configuration information set by the base station through dedicated signaling.

[0022] Here, the dedicated signaling may be signaling transmitted from a base station to a terminal, and the signaling transmits PUR configuration information. The preconfigured uplink resource (PUR) configuration information may be information for configuring preconfigured uplink resources, and may be determined by the base station or determined by predefinition.

[0023] In the embodiment of the present application, the terminal may receive PUR configuration information configured by the base station through dedicated signaling. It is understood that the PUR configuration information may be carried in the dedicated signaling, or the PUR configuration information may be indicated by the dedicated signaling. For example, multiple sets of PUR configuration information may be configured in the terminal, and the corresponding PUR configuration information may be selected based on the dedicated signaling.

[0024] In step 120, a timing advance TA is determined before the time domain position of the PUR resource corresponding to the PUR configuration information in response to determining that the PUR resource belongs to the current location cell.

[0025] Here, Timing Advance (TA) may refer to the amount of time that a system frame in which a UE transmits uplink data precedes a downlink frame during an uplink transmission by the UE.

[0026] For example, a UE in RRC_IDLE or RRC_INACTIVE state may configure a PUR resource based on PUR configuration information, and determine whether the configured PUR resource is a resource of the UE's current cell before the PUR resource is started. If yes, the UE may communicate based on the PUR resource and determine a timing advance (TA).

[0027] In step 130, transmit a physical uplink shared channel (PUSCH) using the TA on the PUR resource in response to being in a target service state, where the target service state represents no radio resource control (RRC) connection with the base station.

[0028] Here, the target state may be the current service state of the UE, specifically, a state in which the terminal has no RRC connection with the base station, such as an RRC_IDLE state or an RRC_INACTIVE state.

[0029] In an embodiment of the present application, when the terminal is in a target service state, the PUSCH may be transmitted in the PUR resource based on the TA, and the PUSCH transmission may be performed.

[0030] In an embodiment of the present application, a base station receives pre-configured uplink resource (PUR) configuration information transmitted by dedicated signaling and configured by the base station, and if it determines that the PUR resource belongs to the current location cell before the time domain position of the PUR resource corresponding to the PUR configuration information, it determines a timing advance (TA) and transmits a PUSCH in the PUR resource according to the TA, thereby realizing channel transmission based on the PUR function in a non-terrestrial network, saving radio resources and reducing the power consumption of the UE.

[0031] In one embodiment, based on the above-described embodiment of the present application, the target service state includes at least one of an RRC_IDLE state and an RRC_INACTIVE state.

[0032] For example, when the terminal is in the RRC_IDLE state or the RRC_INACTIVE state, the terminal may transmit the PUSCH in the PUR resource using the extracted and determined TA.

[0033] In one embodiment, based on the above-described embodiment of the present application, the PUR setting information includes at least one of the following:

[0035] In one embodiment, based on the above-described embodiment of the present application, the PUR configuration information includes PUR resource lists of at least two cells, and each of the PUR resource lists includes: The PUR resource common configuration part includes at least one of a PUR resource common configuration part and a PUR resource cell-level configuration part, where the PUR resource common configuration part includes at least one of a PUR period and a PUR response time window timer (PUR-ResponseWindowTimer), and the PUR resource cell-level configuration part includes at least one of cell identity information, a pre-configured resource uplink terminal search space (PUR-USS), a PUSCH resource configuration, PUSCH resource time-domain start position information, PUSCH resource frequency-domain position information, a TA valid timer, an RSRP change threshold, a USS monitoring maximum time, a pre-configured resource uplink radio network temporary identifier (PUR-RNTI), and the number of valid PUR resources.

[0036] Here, the PUR resource common configuration portion may include a PUR period and a PUR response time window timer PUR-ResponseWindowTimer. The PUR resource cell-level configuration portion may include cell identity information, a pre-configured resource uplink terminal search space PUR-USS, a PUSCH resource configuration, PUSCH resource time domain start position information, PUSCH resource frequency domain position information, a TA valid timer, a reference signal received power RSRP change threshold, a USS monitoring maximum time, a pre-configured uplink resource radio network temporary identifier PUR-RNTI, and the number of valid PUR resources.

[0037] In an embodiment of the present application, PUR configuration information may be configured for a cell, and different cells have various corresponding PUR resource lists, and the PUR resource list may include at least one of information: a PUR resource common configuration part, a PUR resource cell-level configuration part, PUSCH resource time-domain starting position information, PUSCH resource frequency-domain position information, a TA valid timer, an RSRP change threshold, a pre-configured resource uplink radio network temporary identifier PUR-RNTI, and a valid PUR resource number.

[0039] Here, the satellite clock may be clock information in the time domain of wireless communication, and the clock information in the non-terrestrial network may be the satellite clock.

[0040] For example, time domain positions in non-terrestrial networks may be represented using satellite clocks, which may include representations using the absolute time of the satellite clock directly, or a joint representation using the absolute time of the satellite clock plus the relative time of the radio synchronization delay between the terminal and the base station.

[0041] In one embodiment, based on the above-described embodiment of the present application, determining the Timing Advance (TA) includes at least one of obtaining the TA based on historical TA record information and obtaining the TA based on satellite positioning information, and the validity of the historical TA record information is determined by a TA validity timer and / or an RSRP change threshold.

[0042] In one embodiment, based on the above-described embodiment of the present application, the TA effective timer is set by at least one of setting a TA effective timer per UE and setting a TA effective timer in the PUR resource cell level setting part.

[0043] In the embodiment of the present application, the TA valid timer in the PUR setting information may be set for the UE, with each UE corresponding to its own TA valid timer, or the TA valid timer for the PUR resource may be set at the cell level, with each PUR resource in each cell corresponding to one TA valid timer.

[0044] In one embodiment, in the embodiment of the present application, when the base station configures the PUR resource, the configured PUR resource may be obtained from the base station or the base station distributed unit.

[0045] 2 is a flowchart of another channel transmission method provided by an embodiment of the present application, which is applied to supporting PUR transmission in a non-terrestrial network. The method may be implemented by software and / or hardware and is generally integrated into a base station. Referring to FIG. 2, the method provided by an embodiment of the present application specifically includes the following steps:

[0046] In step 210, the terminal's pre-configured uplink resource (PUR) configuration information is configured through dedicated signaling.

[0047] For example, the base station may configure preconfigured uplink resource (PUR) configuration information of the terminal through dedicated signaling, and the dedicated signaling may be signaling transmitted from the base station to the terminal to transmit the PUR configuration information. The preconfigured uplink resource (PUR) configuration information may be information for configuring preconfigured uplink resources, and may be determined by the base station or by a prior definition.

[0048] In step 220, a physical uplink shared channel (PUSCH) transmitted in a PUR resource corresponding to the PUR configuration information is received.

[0049] In an embodiment of the present application, the terminal may configure a PUR resource based on the PUR configuration information and transmit a PUSCH to the base station in the PUR resource. The base station may receive the PUSCH transmitted in the PUR resource corresponding to the PUR configuration information.

[0050] In an embodiment of the present application, the PUR configuration information of the terminal is configured by dedicated signaling, and the PUSCH transmitted in the PUR resource corresponding to the PUR configuration information is received, thereby realizing channel transmission based on the PUR function in the non-terrestrial network, thereby saving radio resources and reducing the power consumption of the UE.

[0051] In one embodiment, based on the above-described embodiment of the present application, the PUR setting information includes at least one of the following:

[0052] That is, it includes at least one of the pre-configured uplink resource response time window timer PUR-ResponseWindowTimer, cell number, pre-configured resource uplink terminal search space PUR-USS, PUSCH resource configuration, PUR period, PUSCH resource time domain start position information, PUSCH resource frequency domain position information, TA valid timer, reference signal received power RSRP change threshold, USS monitoring maximum time, pre-configured uplink resource radio network temporary identifier PUR-RNTI, number of valid PUR resources, serving cell preamble, neighboring cell preamble, serving cell response reference signal configuration, neighboring cell response reference signal configuration, scheduling request resource, and configured grant CG resource.

[0053] In one embodiment, based on the above-described embodiment of the present application, the PUR resource configuration information includes PUR resource lists of at least two cells, each of which includes at least one of a PUR resource common configuration part and a PUR resource cell-level configuration part. Here, the PUR resource common configuration part includes at least one of a PUR period and a PUR response time window timer (PUR-ResponseWindowTimer). The PUR resource cell-level configuration part includes at least one of cell identity information, a pre-configured resource uplink terminal search space (PUR-USS), a PUSCH resource configuration, PUSCH resource time-domain starting position information, PUSCH resource frequency-domain position information, a TA valid timer, an RSRP change threshold, a USS monitoring maximum time, a pre-configured resource uplink radio network temporary identifier (PUR-RNTI), and the number of valid PUR resources.

[0055] For example, the time domain position in a non-terrestrial network may be represented using a satellite clock, and may include a representation using the absolute time of the satellite clock directly, or a joint representation using the absolute time of the satellite clock plus the relative time of the radio synchronization delay between the terminal and the base station.

[0056] In one embodiment, based on the above-described embodiment of the present application, determining the Timing Advance (TA) includes at least one of obtaining the TA based on historical TA record information and obtaining the TA based on satellite positioning information, and the validity of the historical TA record information is determined by a TA validity timer and / or an RSRP change threshold. 3 is a flowchart of another channel transmission method provided by an embodiment of the present application. This embodiment of the present application is an example based on the above-mentioned embodiment of the present application. Referring to FIG. 3, the method provided by the embodiment of the present application specifically includes the following steps:

[0057] In step 310, the terminal's pre-configured uplink resource (PUR) configuration information is configured through dedicated signaling.

[0058] In step 320, a target location cell is determined based on at least one of the terminal's time domain location, terminal movement trajectory, and cell movement trajectory, and a PUR resource is configured.

[0059] In an embodiment of the present application, when a base station configures a PUR resource for a terminal, the base station determines a target location cell based on at least one of information on the time domain location of the terminal, the terminal movement trajectory, and the cell movement trajectory of the terminal, and configures the PUR resource, where the target location cell may be a cell in which the terminal is located when using the PUR resource.

[0060] In step 330, the UR resource is transmitted to the terminal via the cell in which the terminal is currently located.

[0061] For example, the PUR resource may be transmitted to the terminal via the cell in which the terminal is currently located, allowing the terminal to acquire the PUR resource.

[0062] In step 340, a physical uplink shared channel (PUSCH) transmitted in a PUR resource corresponding to the PUR configuration information is received.

[0063] 4 is a flowchart of another channel transmission method provided by an embodiment of the present application. This embodiment of the present application is an example based on the above-mentioned embodiment of the present application. Referring to FIG. 4, the method provided by the embodiment of the present application specifically includes the following steps:

[0064] In step 410, the terminal's pre-configured uplink resource (PUR) configuration information is configured through dedicated signaling.

[0065] In step 420, a target base station for the terminal is determined based on at least one of the time domain location of the terminal, the terminal movement trajectory, and the cell movement trajectory.

[0066] In an embodiment of the present application, the base station may determine a target base station that will provide a PUR resource to the terminal based on at least one of the time domain location of the terminal, the terminal movement trajectory, and the cell movement trajectory, and send a request to the target base station to have the target base station configure the PUR resource for the terminal.

[0067] In step 430, receive the PUR resource set by the target base station and send the PUR resource to the terminal.

[0068] For example, the terminal may receive a PUR resource set by the target base station and transmit the PUR resource to the terminal.

[0069] In step 440, receive a physical uplink shared channel (PUSCH) transmitted on a PUR resource corresponding to the PUR configuration information.

[0070] 5 is a flowchart of another channel transmission method provided by an embodiment of the present application. This embodiment of the present application is an example based on the above-mentioned embodiment of the present application. Referring to FIG. 5, the method provided by the embodiment of the present application specifically includes the following steps:

[0071] In step 510, the terminal's pre-configured uplink resource (PUR) configuration information is configured through dedicated signaling.

[0072] In step 520, the base station centralized unit (CU) requests PUR resources from the base station distributed unit (DU) via a PUR resource request.

[0073] In an embodiment of the present application, a base station central unit (CU) may send a PUR resource request to a base station distributed unit (DU), requesting the DU to configure a PUR resource for a terminal.

[0074] In step 530, the DU sets the PUR resource based on the PUR resource request and sends the PUR resource to the CU.

[0075] For example, the DU sets a PUR resource according to the PUR resource request and sends the PUR resource to the CU, which triggers the transmission of the PUR resource to the terminal.

[0076] In step 540, receive a physical uplink shared channel (PUSCH) transmitted on a PUR resource corresponding to the PUR configuration information.

[0077] In one embodiment, based on the above-described embodiment of the present application, the PUR resource request includes at least one of the following information: target cell identification information, PUR resource message size, PUR resource time domain start position, PUSCH resource period, terminal location information, terminal movement trajectory information, and current location cell location information.

[0078] In one embodiment, based on the above-described embodiment of the present application, the method further includes the CU sending a PUR resource release indication to the DU to release the PUR resource, where the PUR resource release indication includes at least one of target cell identity information, time and / or frequency domain locations of the PUR resource, PUR resource periodicity, and terminal location information.

[0079] For example, the CU may further send a PUR resource release instruction to the DU to cause the DU to release the PUR resource configured for the UE, The PUR resource release instruction may include at least one of identification information of the target cell, the time domain and / or frequency domain location of the PUR resource, the PUR resource period, and UE location information.

[0080] In one embodiment, based on the above-described embodiment of the present application, the DU stores time domain information and frequency domain information of PUR resources, and the CU stores security keys and AS context information for PUR configuration.

[0081] For example, Figure 6 illustrates an example of a channel transmission method provided by an embodiment of the present application. A base station eNB configures a PUR resource configuration for a terminal UE through dedicated signaling. Referring to Figure 6, the channel transmission method may include the following processes:

[0082] In step 1, the base station configures PUR resource information (also referred to as "PUR configuration information") in the UE through dedicated signaling. The PUR configuration information includes at least one of a PUR period, a PUR response time window timer (PUR-ResponseWindowTimer), a cell identity (Cell Identity), a PUR-USS, a PUSCH resource configuration (e.g., UL grant), time-domain location information of the start of a PUSCH resource (e.g., UL grant), frequency-domain location information of the PUSCH resource (UL grant), a TA validity locator, an RSRP change threshold for TA determination, a maximum time for USS monitoring, a PUR-RNTI, and the number of valid PUR resources. The PUR resource configuration information may further include a dedicated preamble, sounding, a scheduling request (SR), and a CG resource for the serving cell or neighboring cell.

[0083] The PUR resources may be those of the UE's current cell or may be a list of PUR resources of one or more other cells.

[0084] In step 2, before the time domain location of the PUR resource, the UE determines whether the PUR dedicated resource configuration belongs to the current location cell. If it does, it first calculates the TA based on information such as satellite positioning, or obtains the TA value based on historical TA record information, and then performs dedicated PUR transmission in the PUR resource using the calculated TA.

[0085] In step 3, if the UE has uplink information to transmit at the start position of the PUR resource, it directly transmits PUSCH in the PUSCH resource using the TA information obtained in step 2.

[0086] In step 4, after transmitting the PUSCH, the UE starts monitoring a physical downlink control channel (PDCCH) offset by n subframes and scrambled with the PUR-RNTI, which is used for physical downlink shared channel (PDSCH) resource scheduling (DL Grant) or PUR transmission acknowledgement (PUR ACK).

[0087] In step 1, When the PUR resource is a PUR resource list of multiple cells, the resource configuration information may be configured for each PUR resource common configuration part (e.g., PUR period, PUR response time window timer PUR-ResponseWindowTimer) and PUR resource cell level configuration part (e.g., cell ID, PUR-USS, PUSCH resource configuration (UL grant), time domain location information of PUSCH resource (UL grant) start, frequency domain location information of PUSCH resource (UL grant), TA validity locator, RSRP change threshold for TA determination, PUR-RNTI, number of PUR resources).

[0088] The time domain location information of the start of the PUSCH resource may be characterized in one of the following ways:

[0089] (1) Absolute Time: Absolute time is in the format [hours:minutes:seconds:ms] with at least millisecond accuracy. The UE clock is derived from the satellite clock.

[0090] (2) Characterization by the form of absolute time and relative time: Absolute time is in the format [hours:minutes:seconds] with at least second accuracy. The UE clock is derived from the satellite clock. Relative time is the system frame number + subframe number and is derived from radio synchronization between the UE and the base station.

[0091] In step 2, if the UE obtains the TA value based on the historical TA record information, the UE needs to store the TA information of the time domain position of the PUR resource. Whether the stored TA information is valid may be determined by the PUR TA validity timer (PUR-TimeAlignmentTimer) and / or the PUR TA validity RSRP change threshold.

[0092] The PUR TA validity timer (PUR-TimeAlignmentTimer) and / or the PUR TA validity RSRP change threshold may be configured per UE or may be configured at the cell level (PUR resource cell level configuration part) of the PUR (configured separately for each cell if the PUR resource is a PUR resource list for multiple cells). When configured per UE, the PUR TA validity timer (PUR-TimeAlignmentTimer) is started or restarted when the UE receives a PUR configuration and restarted after receiving a TAC MAC CE. The RSRP change threshold is based on the RSRP measurement value at the time when the UE last obtained a valid PUR TA.

[0093] When PUR is configured at the cell level, the PUR TA validity timer (PUR-TimeAlignmentTimer) is started or restarted at the PUR resource starting position corresponding to the cell when the UE receives the PUR configuration, and is restarted after receiving the TAC MAC CE of the cell. The change in RSRP of PUR TA validity refers to the RSRP measurement value when the cell obtained the last valid PUR TA.

[0094] If the UE's location cell does not match the cell corresponding to the PUR resource at the time domain location of the PUR resource configuration, the UE automatically releases the configured PUR resource (it may release the UE-level PUR resource, or it may only release the PUR resource of the cell corresponding to the time domain location of the UE's PUR resource configuration), and at the same time, the UE sends the PUR resource release instruction to the base station.

[0095] 7, in step 1, if the PUR resource information configured by the base station for the UE is not for the cell where the UE currently resides, the cell ID corresponding to the PUR resource is carried in the PUR configuration information. The cell ID may be a physical cell identity (PCI) or a cell global identity (CGI). Referring to FIG. 7, if the PUR resource information configured by the base station for the UE belongs to the cell of another base station, the base station first requests PUR resources from the other base station, and then configures the PUR resources allocated by the other base station for the UE.

[0096] 7, in step 1, base station 2 (eNB2) where the UE is located calculates a target cell where the UE is located at the time-domain location of the service based on the time-domain location of the UE, the UE's movement path, and the cell's movement path, and then requests PUR resources from base station 1 (eNB1) to which the target cell belongs. The PUR resource request includes at least one of information on the target cell's identification information, a message size corresponding to the PUR resources, a time-domain starting position of the PUSCH resources, a PUSCH resource period, UE location information, UE movement path information, and location information of the current cell.

[0097] Here, the identification information of the target cell in step 1 and the UE location information, the UE movement trajectory information, or the location information of the currently located cell may be either one of them.

[0098] In step 2, the base station located in the target cell calculates the cell in which the time-domain location of the UE's service is located based on the time-domain location of the UE's service, the UE's movement path, and the cell's movement path, allocates PUR resources to the UE, and transmits the allocated PUR resources to the base station where the UE is currently located. If the UE's service has multiple time-domain locations (e.g., periodic PUR services or multiple service patterns), there may be multiple (list) allocated PUR resources. The allocated PUR resources include at least one of information on cell identity, PUR period, PUR response time window timer (PUR-ResponseWindowTimer), cell ID, PUR-USS, PUSCH resource configuration (UL grant), time-domain location information of the PUSCH resource (UL grant) start, frequency-domain location information of the UL grant, maximum time for USS monitoring, PUR_RNTI, TA validity locator, RSRP change threshold for TA determination, PUR-RNTI, and number of valid PUR resources.

[0099] Referring to FIG. 8, if the base station that allocates PUR resource information to the UE has a CU-DU separated architecture, the CU first requests PUR resources from the DU, and then the PUR resources allocated by the DU are set to the UE.

[0100] In Figure 8, in step 1, a CU requests a PUR resource from a DU. The PUR resource request includes at least one of information on target cell identification information, a message size corresponding to the PUR resource, a time domain starting position of a PUSCH resource, a PUSCH resource period, UE location information, UE movement trajectory information, and location information of a current cell.

[0101] In step 2, the DU calculates the cell in which the time domain location of the UE's service is located based on the time domain location of the UE's service, the UE's movement trajectory, and the cell's movement trajectory, allocates PUR physical layer resources to the UE, and transmits the allocated PUR resources to the CU.

[0102] The DU stores time domain information of PUR resources for PUR reception.

[0103] The CU stores complete information such as UE identification, security keys set by the PUR for data integrity verification and security decryption, data transfer, service process establishment, AS context, etc.

[0104] If the UE's service has multiple time domain locations (e.g., periodic PUR service, multiple service patterns), there may be multiple (list) PUR resources allocated, including at least one of the following information: target cell identification information, PUSCH resource configuration (UL grant), time domain location information of the start of the PUSCH resource (UL grant), and frequency domain location information of the PUSCH resource (UL grant).

[0105] In step 3, if the CU releases the PUR resource, it instructs the DU to release the allocated PUR resource, where the instruction includes at least one of the following information: target cell identity information, time domain and / or frequency domain locations corresponding to the PUR resource, PUSCH resource periodicity, and UE location information.

[0106] The target cell identification information may be a cell index included in a cell CGI or a CU.

[0107] The signaling interaction in steps 1 to 3 may be UE-level signaling without F1 interface connection. The differences from the CG resource request in the case of NR CU-DU separation are as follows: NR (New Radio) allocates CG resources in the UE CONTEXT SETUP or UE CONTEXT MODIFICATION process, which involves UE-level F1 connection, and the CG resources are used by the UE in connected mode. In contrast, the signaling in this flow is intended only for the allocation and / or release of PUR resources, and a dedicated resource request / release flow can be adopted, which does not require a complete F1 interface UE context (the UE's F1-U connection is released immediately after resource allocation is completed, or immediately after the resources are configured for the UE), and the PUR resources are used by the UE in idle mode or RRC_INACTIVE state.

[0108] 9 is a flowchart of a timing advance updating method provided by an embodiment of the present application, which is applied to a case where PUR transmission is supported in a non-terrestrial network. The method may be implemented by software and / or hardware and is generally applied to a UE. Referring to FIG. 9, the method provided by an embodiment of the present application specifically includes the following steps:

[0109] In step 610, update the timing advance of the PUR resource based on the received random access response message.

[0110] Based on the embodiment of the present application, the base station eNB and / or the terminal UE may update the timing advance of the PUR resource based on the received random access response message.

[0111] In one embodiment, based on the above-described embodiment of the present application, updating the timing advance of the PUR resource based on the received random access response message includes:

[0112] If a random access response message carrying a Timing Advance Command (TAC) command is received, the TA validity timer for the PUR resource is restarted.

[0113] For example, when a random access response message containing a TAC command is received, the TA validity timer for the PUR resource may be restarted and a TA update may be performed.

[0114] In one embodiment, based on the above-described embodiment of the present application, updating the timing advance of the PUR resource based on the received random access response message includes:

[0115] In step 611, a random access response message is received and a random access contention resolution process is initiated.

[0116] For example, upon receiving the random access response message, the UE may be controlled to initiate a random access contention resolution process.

[0117] In step 612, if the contention resolution in the random access procedure is successful, restart the TA timer corresponding to the PUR.

[0118] For example, if the contention resolution of the random access procedure is successful, the UE may be controlled to restart the TA timer corresponding to the PUR.

[0119] In one embodiment, based on the above-described embodiment of the present application, updating the timing advance of the PUR resource based on the received random access response message includes:

[0120] In step 621, a random access response message is received, the NTA value before receiving the random access response message is temporarily recorded, and a TA timer is initialized.

[0121] Here, NTA may be a timing offset between uplink and downlink radio frames at the UE, expressed in units of Ts.

[0122] In the embodiment of the present application, upon receiving a random access response message, the NTA value before receiving the random access response message is recorded, and the TA timer is started or restarted to perform initialization.

[0123] In step 622, if the conflict resolution fails, set the NTA to the NTA value before receiving the temporarily recorded random access response message, and if the conflict resolution is successful, delete the NTA value before receiving the temporarily recorded random access response message and set the PUR-TA timer to the value of the TA timer.

[0124] For example, if the contention resolution of the random access procedure fails, set the NTA to the recorded NTA value before the random access response message, and if the contention resolution of the random access procedure is successful, delete the recorded NTA value and set the PUR-TA timer to the value that the TA timer takes.

[0125] In one embodiment, based on the above-described embodiment of the present application, updating the timing advance of the PUR resource based on the received random access response message includes:

[0126] In step 631, a random access response message is received, and the NTA value and the PUR-TA timer value before receiving the random access response message are recorded.

[0127] For example, when a random access response message is received, the NTA value and the PUR-TA timer value are recorded.

[0128] In step 632, the TA timer and the PUA-TA timer are restarted.

[0129] In the embodiment of the present application, the TA timer and the PUA-TA timer are controlled to be restarted for initialization.

[0130] In step 633, if the conflict resolution fails, the NTA value is restored to the temporarily recorded NTA value before the random access response message was received, and the PUR-TA timer is reassigned the sum of the value that the TA timer takes and the recorded value of the PUR-TA timer.

[0131] For example, if contention resolution for the random access procedure fails, set NTA to the temporarily recorded NTA value before the random access response message, and set the PUR-TA timer to the sum of the value taken by the Legacy-TA timer and the recorded PUR-TA timer value.

[0132] In step 634, if the contention resolution is successful, the recorded NTA value and PUR-TA timer value before receiving the random access response message are deleted.

[0133] For example, if the contention resolution of the random access procedure is successful, the recorded NTA value and the PUR-TA timer value are deleted.

[0134] In an exemplary embodiment, the PUR TA and the TA of the Random Access Procedure (RAR) may be jointly processed. After configuring dedicated PUR resources for a UE, when the UE is in an IDLE or inactive state, the UE may transmit on these PUR resources if the UE has uplink data and the TA is valid. After the UE transitions to a connected state, the UE does not release these PUR resources. If the UE transitions to an IDLE or inactive state again, these PUR resources may become available. When the UE receives a TAC MAC CE Alignment Command (TAC) carried by the base station's PDCCH or PUSCH, the UE updates its TA value and starts the associated PUR TA validity timer (if the base station has configured a PUR TA validity timer). If the PUR TA validity timer has not expired, the PUR resource is available; if it has expired, the PUR resource is unavailable.

[0135] When a UE transitions from an IDLE or inactive state to a connected state, the UE may initiate a RACH procedure. If an RAR is received, the RAR carries a TAC. In this case, the UE starts the TA timer used in the connected state and updates the TA value. However, the specification does not specify whether to restart the current PUR TA timer. The above process can cause the following problems:

[0136] 1. In this case, if the RAR is not for this UE and the UE's subsequent RAs continue to fail, after the TA update, the PUR TA Timer may not have expired but the TA may not be available, resulting in a PUR transmission failure.

[0137] 2.At this time, if the base station does not send TAC MAC CE in the connected state and the UE does not restart the PUR TA timer, the TA value has already been updated, so although the TA value is valid, the PUR TA timer may expire, causing the UE to mistakenly believe that PUR is unavailable.If the base station does not send TAC MAC CE in the connected state but the UE restarts the PUR TA timer, the TA value has already been updated, so although the TA value is valid, the PUR TA timer may expire, causing the UE to mistakenly believe that PUR is unavailable.

[0138] The above problem may be solved in the following way.

[0139] In Method 1, when the UE receives an RAR and the RAR carries a TAC command, the UE restarts the PUR TA timer (if configured). After the UE initiates the RACH procedure, the UE receives an RAR, but the RAR received by the UE may not be its own but may be a conflicting RAR from another UE, and the UE cannot identify in the RAR. When the UE receives the RAR, it starts the PUR-related TA timer. If the RAR is not from the UE, the RACH procedure fails. Then, the UE continues to initiate the RACH procedure, and when it receives an RAR, it continues to restart the PUR-related TA timer until it is successful. If the RACH procedure is successful, the UE is synchronized and the PUR-related TA timer is also started.

[0140] In Method 2, after the UE activates the RACH and the contention resolution is successful, the UE starts the PUR-related TA timer (if configured). After the contention resolution is successful, the RAR should belong to the UE, and the TA value carried by the RAR also belongs to the UE. In this case, the UE restarts the PUR-related TA timer.

[0141] In Method 3, the UE maintains two NTA values ​​during the RA procedure. After receiving the RAR, the UE first temporarily records the NTA value before the RAR (PUR-NTA), then starts maintaining the legacy NTA (e.g., uses the TAC in the RAR as the current NTA value (e.g., applies the Timing Advance Command for this TAG)), starts or restarts the legacy TA timer, but does not restart the PUR-TA timer. If the RA conflict resolution fails, the UE restores the legacy NTA value to PUR-NTA. If the RA conflict resolution is successful, the UE deletes PUR-NTA and reassigns the legacy TA timer to the PUR-TA timer.

[0142] In Method 4, the UE maintains two NTA values ​​during the RA procedure. After receiving an RAR, the UE first temporarily records the NTA value before the RAR (PUR-NTA) and the value of the PUR TA timer, then starts maintaining the existing NTA (applies a timing advance command to this TAG), starts or restarts the existing TA timer, and restarts the PUR-TA timer. If the RA conflict resolution fails, the UE restores the existing NTA value to PUR-NTA and reassigns the sum of the existing TA timer and the recorded PUR TA timer to the PUR-TA timer. If the RA conflict resolution is successful, the UE deletes the recorded PUR-NTA and PUR TA timer values.

[0143] 10 is a flowchart of a channel transmission method provided by an embodiment of the present application, which is applied to a case where PUR transmission is supported in a non-terrestrial network. The method may be implemented by software and / or hardware, and is generally integrated into a terminal. Referring to FIG. 10, the method provided by an embodiment of the present application specifically includes the following steps:

[0144] In step 710, common pre-configured uplink resource (PUR) configuration information configured by the base station through common signaling is obtained.

[0145] In an embodiment of the present application, the base station may further configure common pre-configured uplink resource (PUR) configuration information through common signaling, and the terminal may receive the common PUR configuration information and configure a common PUR resource based on the common PUR configuration information.

[0146] In step 720, determine a timing advance TA, and transmit a PUSCH on a common PUR resource corresponding to the common PUR configuration information based on the TA.

[0147] For example, the terminal may determine a timing advance TA and transmit a PUSCH in a common PUR resource corresponding to the common PUR configuration information according to the determined TA.

[0148] In the embodiment of the present application, the UE receives common pre-configured uplink resource (PUR) configuration information set by the base station through common signaling, determines a timing advance (TA), and selects and transmits a PUSCH in the common PUR resource based on the TA, thereby realizing PUR-based channel transmission in a non-terrestrial network, saving radio resources, and reducing the power consumption of the UE.

[0149] In one embodiment, based on the above-described embodiment of the present application, determining the timing advance TA includes:

[0150] Determine TA based on satellite positioning.

[0151] In the embodiment of the present application, the terminal may determine the TA by satellite positioning.

[0152] 11 is a flowchart of another channel transmission method provided by an embodiment of the present application. This embodiment of the present application is an example based on the above-mentioned embodiment of the present application. Referring to FIG. 11, the method provided by the embodiment of the present application specifically includes the following steps:

[0153] In step 810, common pre-configured uplink resource (PUR) configuration information configured by the base station through common signaling is obtained.

[0154] In step 820, if the uplink transmission information is smaller than the PUSCH transmission block size in the common PUR configuration information, determine the TA based on satellite positioning, and select a PUSCH resource from the common PUR resource for transmission.

[0155] In the embodiment of the present application, if the uplink transmission information of the terminal is smaller than the PUSCH transmission block size of the common PUR configuration information, the satellite is used to determine the TA, and a PUSCH resource is selected in the PUR resource to transmit the uplink transmission information.

[0156] In step 830, if the uplink transmission information is equal to or greater than the PUSCH transmission block size of the common PUR configuration information, select a preamble resource and initiate a random access procedure.

[0157] For example, if the uplink transmission information of the terminal is equal to or larger than the PUSCH transmission block size of the common PUR configuration information, the PUSCH is transmitted by starting a random access procedure using the preamble method.

[0158] 12 is a flowchart of another channel transmission method provided by an embodiment of the present application. This embodiment of the present application is an example based on the above-mentioned embodiment of the present application. Referring to FIG. 12, the method provided by the embodiment of the present application specifically includes the following steps:

[0159] In step 910, obtain common pre-configured uplink resource (PUR) configuration information configured by the base station through common signaling.

[0160] In step 920, the TA is determined based on the satellite positioning, and a PUSCH resource is selected from the common PUR resources for transmission.

[0161] In an embodiment of the present application, the terminal UE may determine the TA by satellite positioning, select a PUSCH resource from among the common PUR resources configured by the common PUR configuration information, and perform uplink information transmission.

[0162] In step 930, monitor the PDCCH scrambled with the common PUR-RNTI and enter the PUR CSS monitoring state.

[0163] For example, the terminal transitions to a PUR CSS monitoring state and monitors a PDCCH scrambled with a common PUR-RNTI.

[0164] In step 940, the PDCCH is received and common PUR feedback is received in the downlink resource grant (DL Grant) resources scheduled in the PDCCH.

[0165] In an embodiment of the present application, the terminal may receive a PDCCH and receive common PUR feedback in the DL Grant resource scheduled in the PDCCH.

[0166] In one embodiment, based on the above-described embodiment of the present application, the common PUR feedback includes at least one of the following information: terminal identity information, a cell radio network temporary identifier (C-RNTI), a terminal search space (USS), an uplink resource grant (UL Grant), a downlink resource grant (DL Grant), and a PUR transmission end instruction.

[0167] In one embodiment, based on the above-described embodiment of the present application, the method further includes determining that matching is successful and terminal identification is completed when the terminal identification information in the common PUR feedback matches the local terminal identification information.

[0168] For example, if the terminal identification information in the common PUR feedback matches the local terminal identification information, it is determined that terminal identification is complete.

[0169] In one embodiment, based on the above-described embodiment of the present application, when the terminal identification information in the common PUR feedback matches the local terminal identification information, determining that matching is successful and terminal identification is completed includes: if the common PUR feedback is accompanied by an instruction to terminate the PUR transmission, terminate the common PUR transmission and return to an idle state; If the common PUR feedback includes an indication of a terminal-specific radio network temporary identifier C-RNTI, a USS, a UL grant, and / or a DL grant, transitioning to a PUR USS monitoring state; If the common PUR feedback is accompanied by an RRC connection establishment message, transitioning to an RRC connected state; If the common PUR feedback includes a terminal-specific radio network temporary identifier (C-RNTI) and does not include a USS, configure the USS based on a common search space (CSS) configuration. It includes at least one of the following:

[0170] 13 is a flowchart of a channel transmission method provided by an embodiment of the present application, which is applied to supporting PUR transmission in a non-terrestrial network. The method may be implemented by software and / or hardware and is generally integrated into a base station. Referring to FIG. 13, the method provided by an embodiment of the present application specifically includes the following steps:

[0171] In step 1010, configure common pre-configured uplink resource (PUR) configuration information of the terminal based on the common signaling.

[0172] In the embodiment of the present application, the base station configures common pre-configured PUR configuration information for the terminal through common signaling, and enables the terminal to configure PUR resources according to the common PUR configuration information.

[0173] In step 1020, receive a PUSCH transmitted on a common PUR resource corresponding to the common PUR configuration information.

[0174] For example, the base station may receive the PUSCH transmitted by the terminal using a common PUR resource.

[0175] In an embodiment of the present application, a base station configures common pre-configured uplink resource (PUR) configuration information for a terminal, the common PUR configuration information is transmitted from the base station to the terminal through common signaling, and the base station receives a PUSCH on the common PUR resource corresponding to the common PUR configuration information, thereby realizing channel transmission based on the PUR function in a non-terrestrial network, saving radio resources, and reducing the power consumption of the UE.

[0176] In one embodiment, based on the above-described embodiment of the present application, the method further includes transmitting a PDCCH scrambled with a common PUR-RNTI to the terminal to control the terminal to receive the common PUR feedback, and transmitting the common PUR feedback to the terminal in the resource of the DL Grant.

[0177] In an embodiment of the present application, the base station may scramble the PDCCH by the common PUR-RNTI and transmit the PDCCH to the terminal to control the terminal to receive the common PUR feedback. After transmitting the PDCCH, the base station may transmit the common PUR feedback to the terminal in the DL Grant resource.

[0178] In one embodiment, based on the above-described embodiment of the present application, the common PUR feedback includes at least one of the following information:

[0179] That is, it includes at least one of the following information: terminal identification information, cell radio network temporary identifier C-RNTI, terminal search space USS, uplink resource grant UL Grant, downlink resource grant DL Grant, and PUR transmission end instruction.

[0180] In one exemplary embodiment, referring to Figure 14, the configuration and transmission of common PUR resources may include the following steps: In step 1, a base station configures common PUR resource information in a UE through common signaling (SIB: System Information Block), where the common PUR resource information includes at least one of a common PUSCH resource configuration, a PUR CSS configuration, and a common PUR_RNTI.

[0181] The common PUSCH resource configuration includes at least one of a time domain starting position of a PUSCH resource, a periodicity of a PUSCH resource, a frequency domain position of a PUSCH resource, physical layer scheduling information of a PUSCH resource, and the like.

[0182] The PUR CSS setting may be an RA-CSS or a PUR CSS explicitly set by the base station.

[0183] The common PUR_RNTI may be a PUR-RNTI calculated by the UE based on the time-domain and frequency-domain positions of the common PUSCH resource, or a PUR-RNTI set to the UE by the base station through signaling, or may be any RNTI predefined in the specification.

[0184] In step 2, when the UE needs to perform uplink transmission, the cell where the UE is located has common PUR configuration information.

[0185] In the control plane data transmission method, if the uplink transmission information is smaller than the transport block size (TB Size) that can be transmitted on the PUSCH in the PUR configuration information, the TA is calculated based on information such as satellite positioning, and a PUSCH resource is selected in the common PUR resource information to perform common PUR transmission. Otherwise, a preamble resource is selected and a PRACH procedure is initiated.

[0186] In the user plane data transmission method, the TA is calculated based on information such as satellite positioning, and a PUSCH resource is selected from the common PUR resource information to perform common PUR transmission. If the PUSCH resource cannot carry all the user data during common PUR transmission, the remaining data segments may be transmitted on dedicated PUSCH resources scheduled on the PDCCH after step 5 (after successful UE identification), or may be transmitted on dedicated PUSCH resources scheduled on the PDCCH after the UE transitions to connected mode.

[0187] The uplink information transmission includes UE identification information and at least includes user data, RRC Msg3 signaling.

[0188] The UE identity information may be a Non Access Stratum (NAS) UE identity information or a UE identity information assigned by a network side. The UE identity information may be included in a MAC CE or RRC signaling.

[0189] In step 3, after the UE performs the common PUR transmission, it monitors the PDCCH offset backward by n subframes and scrambled with the common PUR_RNTI, and enters the PUR CSS monitoring state.

[0190] In step 4, the UE receives the PDCCH scrambled with the common PUR_RNTI.

[0191] In step 5, the UE receives a common PUR Response in the resources of the DL Grant scheduled by the PDCCH scrambled with the common PUR_RNTI.

[0192] The common PUR response may include at least one of UE identification information, a UE specific C-RNTI, a USS, an UL Grant, a DL Grant, and a PUR transmission end instruction.

[0193] In step 6, the UE compares its own UE identity information according to the received UE identity information, and if the match is successful, the UE completes the identification. Specifically, the method may include:

[0194] 1. If the PUR Response carries a PUR transmission end indication, the UE ends the common PUR transmission and returns to idle state.

[0195] 2. If the PUR Response carries UE-specific C-RNTI, USS, UL Grant and / or DL ​​Grant indication, transition to PUR USS monitoring state (subsequent processing is the same as the current PUR flow and can be easily supplemented).

[0196] 3. If the PUR Response carries an RRC connection establishment message, the UE transitions to the RRC connected state.

[0197] 4. If the PUR Response carries a UE-specific C-RNTI but does not carry a PUR USS, the PUR USS uses the PUR CSS settings.

[0198] 15 is a schematic diagram of a channel transmission device according to an embodiment of the present application. The device can implement the channel transmission method according to any embodiment of the present application, and can realize functional modules corresponding to specific implementation methods to achieve beneficial effects. The device can be implemented in software and / or hardware, and specifically includes a setting receiving module 11, a timing advance module 12, and a channel transmission module 13.

[0199] The configuration receiving module 11 is configured to receive pre-configured uplink resource (PUR) configuration information configured by the base station through dedicated signaling.

[0200] The timing advance module 12 is configured to determine a timing advance TA before a time domain position of a PUR resource corresponding to the PUR configuration information, in response to determining that the PUR resource belongs to a current location cell.

[0201] The channel transmission module 13 is configured to transmit a physical uplink shared channel (PUSCH) using the TA in the PUR resource in response to being in a target service state, where the target state represents no radio resource control (RRC) connection with a base station.

[0202] In this embodiment, the configuration receiving module 11 receives pre-configured uplink resource PUR configuration information configured by the base station and transmitted via dedicated signaling. The timing advance module 12 determines a timing advance TA before the time domain position of the PUR resource corresponding to the PUR configuration information if it determines that the PUR resource belongs to the current location cell. The channel transmission module 13 transmits a PUSCH in the PUR resource based on the TA when in a target service state. This realizes channel transmission based on the PUR function in a non-terrestrial network, saves radio resources, and reduces the UE's power consumption.

[0203] In one embodiment, in the embodiment of the present application described above, the target service state of the device includes at least one of an RRC_IDLE state, an RRC_INACTIVE state.

[0206] In one embodiment, based on the above-described embodiment of the present application, the PUR configuration information in the device includes PUR resource lists of at least two cells, each of which includes at least one of a PUR resource common configuration part and a PUR resource cell-level configuration part, where the PUR resource common configuration part includes at least one of a PUR period and a PUR response time window timer (PUR-ResponseWindowTimer), and the PUR resource cell-level configuration part includes at least one of cell identity information, a pre-configured resource uplink terminal search space (PUR-USS), a PUSCH resource configuration, PUSCH resource time-domain starting position information, PUSCH resource frequency-domain position information, a TA valid timer, an RSRP change threshold, a USS monitoring maximum time, a pre-configured resource uplink radio network temporary identifier (PUR-RNTI), and the number of valid PUR resources.

[0207] In one embodiment, based on the above-described embodiment of the present application, the time domain location information of the PUSCH resource in the device is: Absolute time based on the satellite clock, and It is represented by at least one of an absolute time based on the satellite clock and a joint representation of relative time that is radio-synchronized to the base station.

[0208] In one embodiment, based on the above-described embodiment of the present application, the timing advance module 12 comprises a history information unit and a satellite determination unit.

[0209] The history information unit is configured to obtain a TA based on historical TA record information, the validity of which is determined by a TA validity timer and / or an RSRP change threshold.

[0210] The satellite determining unit is configured to obtain the TA based on the satellite positioning information.

[0211] In one embodiment, based on the above-described embodiment of the present application, the TA valid timer in the device is: Setting the TA valid timer for each UE, and It is set by at least one of the settings of the TA valid timer in the PUR resource cell level configuration part.

[0212] 16 is a schematic diagram of a channel transmission device provided by an embodiment of the present application. The device can implement the channel transmission method provided by any embodiment of the present application, and realize functional modules corresponding to specific implementation methods to achieve beneficial effects. The device can be implemented in software and / or hardware, and specifically includes an information setting module 21 and a channel receiving module 22.

[0213] The information setting module 21 is configured to set pre-configured uplink resource (PUR) setting information of the terminal through dedicated signaling.
