Description

Technical Field

[0001] (Cross - reference to related applications) This application claims the priority of Chinese Patent Application No. 202010525854.7 filed in China on June 10, 2020, and all of its contents are incorporated herein by reference. (Technical Field) This disclosure relates to the technical field of mobile communication, and particularly relates to information transmission methods, reception methods, and devices.

Background Art

[0002] Conditional HandOver (CHO) is a mechanism to enhance the robustness of handover and secondary node addition. To solve the problem that the channel between the terminal UE (User Equipment) and the serving cell deteriorates suddenly (especially at high frequencies), making it impossible for the UE to complete the handover or secondary node addition process normally, the base station is configured to trigger the measurement report by the UE at a relatively low threshold, and carry a relatively high handover trigger threshold in the HandOver (HO) command or secondary node addition command. Further, it carries the random access resource used by the UE in the target cell. In this way, the base station can receive the measurement report before the handover threshold is satisfied. When the handover threshold is satisfied, the UE starts the random access process for the target base station or cell. The source base station or cell can configure conditional handover for the UE to multiple target cells.

[0003] Similarly, a Conditional Pscell Change (CPC) is a process in which a network-side master node (MN) or secondary node (SN) sends the conditions for a primary / secondary cell change (PSCell Change) to a terminal in advance, and the terminal spontaneously performs the Pscell Change when it determines that the conditions for the target Pscell are met. A primary / secondary cell (PSCell) is sometimes also called the primary service cell of a secondary cell group.

[0004] Conditional Handover CHOs and Conditional Primary / Secondary Cell Change CPCs are not triggered by the network sending a handover command to the UE, but are automatically triggered on the terminal side based on events where the UE's measurement results match the network's configuration. Therefore, the network side does not know the specific time when the CHO or CPC is triggered, the UE's location, or the UE's measurement results. Furthermore, if the network side configures two events for the UE, the network side does not know which event was met to trigger the CHO or CPC. As a result, it becomes difficult for the network side to obtain the relevant information when the CHO and CPC are triggered, and it becomes impossible to optimize the trigger events or flows based on the aforementioned relevant information.

Furthermore, features described in reference to some examples may be combined in other examples.

[0036] Refer to Figure 1. Figure 1 shows a block diagram of an applicable wireless communication system according to an embodiment of the present disclosure. The wireless communication system includes a terminal 11 and network equipment 12. Here, terminal 11 is also called a user terminal or user equipment (UE). Terminal 11 may be a terminal-side device such as a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, or in-vehicle equipment. In the embodiments of the present disclosure, the specific type of terminal 11 is not limited. Network equipment 12 may be a base station or a network element of a core network. Here, the base station may be a base station of a 5G or later version (e.g., gNB, 5G NR NB, etc.) or a base station in another communication system (e.g., eNB, WLAN access point, or other access point, etc.). Here, a base station may be referred to as Node B, Advanced Node B, Access Point, Base Transceiver Station (BTS), Radio Base Station, Radio Transceiver, Basic Service Set (BSS), Extended Service Set (ESS), B Node, Advanced B Node (eNB), Home B Node, Home Advanced Node B, WLAN Access Point, WiFi Node, or any other appropriate term in the field. The term "base station" is not limited to any particular technical term as long as it achieves a similar technical effect. In the embodiments of this disclosure, a base station in an NR system is described simply as an example, but the specific type of base station is not limited.

[0037] A base station communicates with a terminal 11 under the control of a base station control unit, and in various examples, the base station control unit is part of a core network or several base stations. Some base stations can communicate control information or user data with the core network through backhaul. In some examples, some of these base stations communicate with each other directly or indirectly through backhaul links, which are wired or wireless links. Wireless communication systems support operation with multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit a modulated signal on multiple carriers simultaneously. For example, each communication link is a multi-carrier signal modulated according to various wireless technologies. Each modulated signal is transmitted on a different carrier and carries control information (e.g., reference signal, control channel, etc.), overhead information, data, etc.

[0038] A base station communicates wirelessly with a terminal 11 via one or more access point antennas. Each base station provides communication coverage to its respective coverage area. The coverage area of ​​an access point is divided into sectors that constitute only a portion of the coverage area. The wireless communication system includes different types of base stations, such as macro base stations, micro base stations, or pico base stations. Base stations also utilize different radio technologies, such as cellular or WLAN wireless access technologies. Base stations are associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of the same or different types of base stations, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

[0039] A communication link in a wireless communication system includes an uplink for carrying uplink (UL) transmission (for example, transmission from terminal 11 to network equipment 12) or a downlink for carrying downlink (DL) transmission (for example, transmission from network equipment 12 to terminal 11). UL transmission is also called reverse link transmission, and DL transmission is also called forward link transmission. Downlink transmission is carried out using authorized frequency bands, unauthorized frequency bands, or both. Similarly, uplink transmission is carried out using authorized frequency bands, unauthorized frequency bands, or both.

[0040] Figure 2 shows an example flowchart of a Conditional Handover (CHO) related technology. Here, the terminal (UE) submits a measurement report based on a relatively low threshold configured by the base station (step 21). The service base station makes a handover decision based on the measurement report previously submitted by the terminal and sends a pre-handover request to the target base station candidate (step 22). The target base station accepts the handover request, establishes an RRC configuration, and sends a handover confirmation to the source base station (step 23). The source base station sends a conditional handover command to the terminal based on a higher threshold (step 24). Upon receiving the conditional handover command from the source base station, the terminal temporarily suspends the handover, and if the measurement result meets the condition of the higher threshold, it triggers a conditional handover, initiates the synchronization and random access process (step 25), and then completes the handover process through the handover flow (steps 26-27).

[0041] In a conditional handover process, the handover events that can be configured for each target base station candidate are A3 events and / or A5 events. Here, an A3 event means that the neighbor cell signal quality is better than that of the primary cell / primary secondary cell and is also better than a certain offset amount. An A5 event means that the primary cell / primary secondary cell signal quality is worse than a certain absolute threshold and the neighbor cell / secondary cell signal quality is better than another absolute threshold (PCell / PCell becomes worse than absolute threshold 1 AND Neighbor / Cell becomes better than another absolute threshold 2).

[0042] Correspondingly, the network side needs to configure a measurement quantity corresponding to the trigger event, namely one of the following: Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or Signal-to-Noise and Interference Ratio (SINR). Furthermore, it needs to configure the trigger time (TTT), threshold (including a3-Offset, a5-Threshold1, a5-Threshold2), hysteresis amount, and offset amount (Ofn, Ocn, Off, and Ocp, etc.).

[0043] Conditional handovers and conditional secondary cell change (CPC) events are triggered not by the network sending a handover command to the UE, but by events where the UE's measurement results match the network's configuration. Therefore, the network does not know the specific time when a conditional handover or CPC is triggered, the UE's location, or the UE's measurement results. Furthermore, if the network has configured two events for the UE, it does not know which event triggered the conditional handover or CPC. Due to this lack of information, it is difficult for the network to optimize the events and flows described above.

[0044] To solve at least one of the above problems, an embodiment of the present disclosure provides an information transmission method in which the terminal records and reports relevant information when an event is triggered during a conditional handover and conditional secondary cell change process, thereby contributing to the optimization of the corresponding flow by optimizing the above event and configuration parameters on the network side, and reducing subsequent similar failures.

[0045] In the embodiments of this disclosure, the triggering of an event is considered equivalent to the event being satisfied; that is, the triggering of an event is also referred to as the event being satisfied. Correspondingly, the trigger order is also referred to as the satisfaction order, and the trigger time is also referred to as the satisfaction time.

[0046] Referring to Figure 3, the information transmission method according to the embodiment of this disclosure, when applied to the terminal side, includes the following:

[0047] In step 31, the terminal records information regarding conditional handovers and / or conditional primary / secondary cell changes.

[0048] Here, the information regarding the conditional handover and / or conditional primary / secondary cell change CPC includes at least one of the following: 1) A trigger event for the conditional handover and / or conditional primary / secondary cell change, which includes at least one of the A3 event and / or A5 event. 2) Information about the beam measured when the trigger event is triggered. Specifically, the beam information measured when the trigger event is triggered includes at least one of the following: the beam IDs of the service cell, target cell, and adjacent cell; the beam measurement result; and the number of beams in the cell whose beam quality exceeds a preset threshold. The service cell and target cell each include a primary cell PCell and / or a primary secondary cell PSCell. 3) Metric information corresponding to the trigger event. Specifically, the indicator information corresponding to the trigger event includes at least one of the following: measurement quantity (such as RSRP, RSRQ, or SINR), type of reference symbol (SS / PBCH block or CSI-RS), trigger time TTT (TimeToTrigger), threshold corresponding to the trigger event (such as a3-Offset, a5-Threshold1, a5-Threshold2), hysteresis amount, and offset amount (such as Ofn). 4) If both A3 and A5 events are configured, at least one of the following pieces of information: The trigger order of the aforementioned A3 event and A5 event, or The time difference between the triggering of the aforementioned A3 event and the A5 event, or When the first event is triggered, the measurement information and index information corresponding to the second event, or When the second event is triggered, measurement information and index information corresponding to the first event. Here, the first event and the second event are the events that are triggered before and after the aforementioned A3 event and A5 event. For example, specifically, the following: 4A) Pre-triggered events. An example is an A3 event based on RSRP. 4B) Information about events that have not yet been triggered when a pre-triggered event is triggered. Examples include A5 events (which do not need to be explicitly specified), TTT timing status, measurement quantities used for A5 events (i.e., RSRP, RSRQ, or SINR), type of reference code (e.g., SS / PBCH block or CSI-RS), service cells to be measured, cell-level and beam-level measurement results of adjacent cell quantities (e.g., RSRQ), and the number of beams. 4C) Information about the pre-trigger event when a post-trigger event is triggered. Examples include the A3 event, the TTT timing status (not stopping timing after the A3 trigger), the measurement quantity used for the A3 event (i.e., RSRP, RSRQ, or SINR), the type of reference symbol (e.g., SS / PBCH block or CSI-RS), the cell-level and beam-level measurement results of the quantity (e.g., RSRP) of the service cell, target cell, and adjacent cell to be measured, and the number of beams. 4D) The time difference between when a later trigger event is triggered and when a earlier trigger event is triggered. 5) If a conditional primary-secondary cell change (CPC) is configured, both the MN and SN can configure the CPC on the terminal, so they may record the node on which the information regarding the conditional primary-secondary cell change (CPC) is configured. The node includes a master node (MN) and a secondary node (SN). 6) If both a conditional handover and a conditional primary / secondary cell change (CPC) are configured, information to indicate the current scene. The current scene is the conditional handover and the conditional primary / secondary cell change (CPC).

[0049] In step 32, the terminal transmits information regarding the conditional handover and / or conditional primary / secondary cell change to the network.

[0050] Here, the terminal transmits information regarding the conditional handover and / or conditional primary / secondary cell change to the network while it is in an idle, inactive, or connected state, or in the process of transitioning to a connected state. For example, the terminal transmits the above information via a random access report, a connection establishment report, a wireless link failure report, or a predefined message.

[0051] By following the steps described above, in the embodiments of this disclosure, the terminal can record relevant information when triggering a conditional handover and / or conditional primary / secondary cell change and transmit the information to the network, thereby informing the network of the specific trigger events for the conditional handover and / or conditional primary / secondary cell change. This helps the network optimize the relevant events or flows based on the information, thereby improving the communication performance of the system.

[0052] In at least one embodiment of the present disclosure, the information relating to the conditional handover and / or conditional primary secondary cell change may further include at least one of the following: 7) Information about the cell measured when the trigger event was triggered. The cell includes a service cell, a target cell, and the measured adjacent cell, where the service cell and the target cell include a primary cell (PCell) and / or a primary secondary cell (PSCell), respectively. The cell information includes cell-level information such as a cell identifier, cell measurement result, and beam ID. 8) The time and location information of the UE when the conditional handover and / or conditional primary / secondary cell change is triggered, and measurement results of wireless LAN (WLAN) and / or Bluetooth®.

[0053] According to at least one embodiment of the present disclosure, the terminal transmits information regarding the conditional handover and / or conditional primary-secondary cell change. Specifically, the terminal proactively transmits information regarding the conditional handover and / or conditional primary-secondary cell change to the network. For example, the terminal transmits the information to the network according to a predetermined time period or when locally recorded information reaches a predetermined number.

[0054] According to at least one embodiment of the present disclosure, the terminal transmitting the conditional handover and / or conditional primary / secondary cell change information may be the terminal transmitting the conditional handover and / or conditional primary / secondary cell change information to the network in response to a request message after receiving the request message from the network. Optionally, before receiving the request message, the terminal transmits a log of the conditional handover and / or conditional primary / secondary cell change information to the network. For example, the log is transmitted to the network when locally recorded conditional handover and / or conditional primary / secondary cell change information matches a preset condition. The preset condition may include the locally recorded information reaching a preset number or the recording of specific preset information.

[0055] In the embodiments of this disclosure, the information to be recorded by the terminal is configured by the network. Specifically, the terminal receives configuration information transmitted from the network and, based on the configuration information, configures the information regarding the conditional handover and / or conditional primary / secondary cell change CPC that the terminal should record. In another implementation, the information to be recorded may be predetermined. For example, certain configuration information may be stored locally in advance of the terminal. In this way, the terminal configures the information regarding the conditional handover and / or conditional primary / secondary cell change that the terminal should record based on the information stored locally in advance of the terminal.

[0056] The above describes the method of transmitting information from the terminal side in the embodiment of this disclosure. Below, we will introduce the implementation of the embodiment of this disclosure from the network side.

[0057] Referring to Figure 4, embodiments of this disclosure provide an information receiving method applied to network-side equipment. Specifically, the network-side equipment includes devices such as base stations, gateways, or trace collection entities (TCEs). As shown in Figure 4, the information receiving method includes the following:

[0058] In step 41, the network-side equipment receives information from the terminal regarding a conditional handover and / or a conditional primary / secondary cell change. Here, the information regarding the conditional handover and / or conditional primary / secondary cell change CPC includes at least one of the following: 1) A trigger event for the conditional handover and / or conditional primary / secondary cell change, which includes at least one of the A3 event and / or A5 event. 2) Information about the beam measured when the trigger event is triggered. Specifically, the information regarding the beam measured when the trigger event is triggered is: The service cell, target cell, and adjacent cell each include at least one of the following: beam IDs, beam measurement results, and the number of beams in a cell whose beam quality exceeds a preset threshold. The service cell and target cell each include a primary cell PCell and / or a primary secondary cell PSCell. 3) Metric information corresponding to the trigger event. Specifically, the indicator information corresponding to the trigger event includes at least one of the following: measurement quantity (such as RSRP, RSRQ, or SINR), type of reference symbol (SS / PBCH block or CSI-RS), trigger time TTT (TimeToTrigger), threshold corresponding to the trigger event (such as a3-Offset, a5-Threshold1, a5-Threshold2), hysteresis amount, and offset amount (such as Ofn). 4) If both A3 and A5 events are configured, at least one of the following pieces of information: The trigger order of the aforementioned A3 event and A5 event, or The time difference between the triggering of the aforementioned A3 event and the A5 event, or When the first event is triggered, the measurement information and index information corresponding to the second event, or When the second event is triggered, measurement information and index information corresponding to the first event. Here, the first event and the second event are the events that are triggered before and after the aforementioned A3 event and A5 event. For example, specifically, the following: 4A) Pre-triggered events. An example is an A3 event based on RSRP. 4B) Information about events that have not yet been triggered when a pre-triggered event is triggered. Examples include A5 events (which do not need to be explicitly specified), TTT timing status, measurement quantities used for A5 events (i.e., RSRP, RSRQ, or SINR), type of reference code (e.g., SS / PBCH block or CSI-RS), service cells to be measured, cell-level and beam-level measurement results of adjacent cell quantities (e.g., RSRQ), and the number of beams. 4C) Information about the pre-trigger event when a post-trigger event is triggered. Examples include the A3 event, the TTT timing status (not stopping timing after the A3 trigger), the measurement quantity used for the A3 event (i.e., RSRP, RSRQ, or SINR), the type of reference symbol (e.g., SS / PBCH block or CSI-RS), the cell-level and beam-level measurement results of the quantity (e.g., RSRP) of the service cell, target cell, and adjacent cell to be measured, and the number of beams. 4D) The time difference between when a later trigger event is triggered and when a earlier trigger event is triggered. 5) If a conditional primary-secondary cell change (CPC) is configured, both the MN and SN can configure the CPC on the terminal, so they may record the node on which the information regarding the conditional primary-secondary cell change (CPC) is configured. The node includes a master node (MN) and a secondary node (SN). 6) If both a conditional handover and a conditional primary / secondary cell change (CPC) are configured, information to indicate the current scene. The current scene is the conditional handover and the conditional primary / secondary cell change (CPC).

[0059] Through the above steps, network-side devices can receive specific trigger events that trigger conditional handovers and / or conditional primary / secondary cell changes, allowing them to understand the specific causes of conditional handovers and / or conditional primary / secondary cell changes by terminals, and providing reference information for optimizing subsequent events or flows.

[0060] In at least one embodiment of the present disclosure, the information relating to the conditional handover and / or conditional primary secondary cell change may further include at least one of the following: 7) Information about the cell measured when the trigger event was triggered. The cell includes a service cell, a target cell, and the measured adjacent cell, where the service cell and the target cell include a primary cell (PCell) and / or a primary secondary cell (PSCell), respectively. The cell information includes cell-level information such as a cell identifier, cell measurement result, and beam ID. 8) The time and location information of the UE when the conditional handover and / or conditional primary / secondary cell change is triggered, and measurement results of Wi-Fi (WLAN) and / or Bluetooth.

[0061] Optionally, prior to step 41 above, the network-side device transmits configuration information to a terminal and configures the information regarding the conditional handover and / or conditional primary-secondary cell change CPC to be recorded by the terminal.

[0062] In step 41 above, the network-side device receives information regarding the conditional handover and / or conditional primary / secondary cell change CPC that is proactively transmitted from the terminal. Alternatively, the network-side device sends a request message to the terminal and receives information regarding the conditional handover and / or conditional primary / secondary cell change CPC transmitted from the terminal based on the request message. Optionally, before sending the request message, the network-side device receives a log of the information regarding the conditional handover and / or conditional primary / secondary cell change CPC transmitted from the terminal, and sends the request message to the terminal based on the log.

[0063] Following step 41 above, the network-side equipment optimizes the events and parameters of the conditional handover and / or conditional primary / secondary cell change based on the information regarding the conditional handover and / or conditional primary / secondary cell change, the Random Access Channel (RACH) report, and the Radio Link Failure (RLF) report. Specifically, this includes at least one of the following: 1) If, based on the information regarding the conditional handover and / or conditional primary / secondary cell change, it is determined that the terminal has triggered a conditional handover and handed over to the target cell, and based on the random access channel report or wireless link failure report information, it is determined that the terminal has handed over to the source cell again after handing over to the target cell, and the time interval between the two handovers is smaller than a preset time threshold, then the threshold for the related event that triggers the conditional handover is adjusted to raise the triggering hurdle for the related event. For example, if a network-side device determines that the UE has accelerated the handover for an A3 or A5 event, meaning the UE triggered a conditional handover, but then reconfigured back to the original cell due to a sudden wireless link failure after the UE had handed over to the target cell, it will raise the handover threshold by increasing the a3-Offset, lowering the a5-Threshold1, raising the a5-Threshold2, and increasing the TTT. 2) If, based on the information regarding the conditional handover and / or conditional primary / secondary cell change, it is determined that the terminal has triggered a conditional handover and handed over to a target cell, and based on the random access channel report or wireless link failure report information, it is determined that the terminal has handed over to another cell different from the source cell after handing over to the target cell, and the time interval between the two handovers is smaller than a preset time threshold, the threshold for the related event that triggers the conditional handover is adjusted to lower the triggering hurdle for the related event. For example, if network-side equipment determines that the UE is late in handing over an A3 or A5 event, meaning the UE has caused an RLF in a service cell and rebuilt in another cell, it needs to lower the handover hurdle by lowering the a3-Offset, raising the a5-Threshold1, lowering the a5-Threshold2, and raising the TTT. 3) Based on the information regarding the conditional handover and / or conditional primary / secondary cell change, if the network determines that the interval between the event times of A3 and A5 events configured simultaneously is greater than a preset time, the threshold for triggering the pre-triggered event is raised and / or the threshold for triggering the post-triggered event is lowered. For example, if a network device configures both A3 and A5 events for the UE, but there is a large time difference between the triggering of the two events, such that A3 is triggered long before A5 is triggered, it indicates that the A3 event is not functioning or that it relies solely on the A5 event. In this case, the trigger threshold for A3 should be raised or the trigger threshold for A5 should be lowered so that the two events can work together better. 4) Depending on whether the UE reports CPC or CHO information, network-side equipment can accurately determine whether the event to be coordinated is a CHO or a CPC. 5) Depending on whether the configuration information reported by the UE comes from the MN or the SN, the network-side equipment can notify the MN or SN to adjust the parameters of the corresponding event.

[0064] The various methods of the embodiments described herein have been introduced above. Further, an apparatus for carrying out the above methods is provided below.
