[0032] The technical solutions in this application will now be described with reference to the accompanying drawings.
[0033] Wireless communication system Figure 1 This is a system architecture example diagram of a wireless communication system 100 applicable to embodiments of this application. The wireless communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 can provide network coverage for a specific geographical area and can communicate with the terminal device 120 located within that coverage area. The terminal device 120 can access a network (such as a wireless network) through the network device 110. Optionally, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity; this application embodiment does not limit this.
[0034] It should be understood that the technical solutions of the embodiments of this application can be applied to various communication systems, such as 5G systems or new radio (NR), long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, etc. The technical solutions provided in this application can also be applied to future communication systems, such as sixth-generation mobile communication systems, satellite communication systems, and so on.
[0035] The terminal device in this application embodiment can also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The terminal device in this application embodiment can be a device that provides voice and / or data connectivity to a user, and can be used to connect people, objects, and machines, such as a handheld device with wireless connectivity, vehicle-mounted device, etc. The terminal devices in the embodiments of this application can be mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, self-driving, remote medical surgery, smart grids, transportation safety, smart cities, and smart homes, etc. Optionally, the terminal device can act as a base station. For example, the terminal device can act as a dispatching entity, providing sidelink signals between terminal devices in vehicle-to-everything (V2X) or device-to-device (D2D) systems. For instance, cellular phones and cars communicate with each other using sidelink signals. Cellular phones and smart home devices communicate without relaying communication signals through base stations.
[0036] The network device in this application embodiment can be a device for communicating with terminal devices. This network device can be, for example, an access network device or a wireless access network device. For instance, the network device can be a base station. The term "base station" can broadly encompass various names such as, or be replaced by, the following: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), femtocell, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or the like, or a combination thereof.
[0037] Terminal devices can communicate with each other via sidelinks. Sidelink communication is also known as proximity services (ProSe) communication, one-way communication, sidelink communication, or D2D communication.
[0038] Measurement gap (MG) To enable inter-frequency or intra-frequency measurements, the concept of a measurement gap is introduced. In NR, a gap can include the measurement gap configuration for each terminal device or for each frequency range (FR). Regardless of the granularity of the configuration, it must include the measurement gap length (MGL), the measurement gap repetition period (MGRP), and the gap offset (GO). MGL represents the length of the measurement gap. For example, an MGL of 6ms means that within these 6ms, the terminal device needs to perform intra-frequency or inter-frequency measurements and cannot transmit data on the currently serving cell corresponding to the frequency point associated with the measurement gap configuration. MGRP represents the repetition period of the measurement gap; for example, an MGRP of 40ms means a measurement gap occurs every 40ms. GO identifies the offset position of the measurement gap repetition period.
[0039] During the measurement gap, the terminal equipment must cease normal uplink and downlink data transmission on the serving cell in the corresponding frequency domain until the measurement gap ends. Specific regulations are as follows: During measurement intervals, the media access control (MAC) entity shall perform the following: 1> Do not perform the transmission of hybrid automatic repeat request acknowledgement (HARQ), channel-state information (CSI), and scheduling request (SR); 2> Do not report the sounding reference signal (SRS); 3> Except for message 3 (msg3), it is not transmitted on the uplink shared channel (UL-SCH); 4> If the ra-ResponseWindow or ra-ContentionResolution timer is running, the physical downlink control channel (PDCCH) is monitored as specified in sub-clauses 5.1.4 and 5.1.5; otherwise, the PDCCH is not monitored and no reception is performed on the downlink shared channel (DL-SCH).
[0040] No measurement gap configured Unlike LTE, NR measurements are divided into two types: those with configured measurement intervals and those without. When the neighboring cell synchronization signal block (SSB) satisfying the co-frequency measurement is completely contained within the bandwidth part (BWP) activated by the terminal device, or when the activated downlink BWP is the initial BWP, the co-frequency measurement does not require a configured measurement interval. Otherwise, the co-frequency measurement requires a configured measurement interval.
[0041] In the R16 RRM enhancement project, an important issue is the enhancement of inter-frequency measurements without measurement gaps. If the needforgap information for the current inter-frequency point reported by the terminal device or configured by the network indicates that a gap is required (“gap”), and the terminal device supports the capability of inter-frequency measurements without gaps, then once the target SSB falls within the terminal device's active BWP, the terminal device is still allowed to perform measurements without gaps outside the gap. If the needforgap information for the current inter-frequency point reported by the terminal device or configured by the network indicates that a gap is not required (“no-gap”), it is directly determined that the terminal device does not require gaps for measurements at the corresponding frequency point, without needing to determine whether the terminal device supports the capability of inter-frequency measurements without gaps.
[0042] In measurement scenarios where gaps are not required, the following restrictions apply to the transmission and reception behavior of terminal devices: The scheduling restrictions are illustrated below using SSB-based co-frequency measurements without gaps as an example. In Release 15, simultaneously receiving data with different subcarrier spacings (SCS) and SSBs is defined as an optional capability for terminal devices. From the perspective of terminal device implementation, a terminal device with this capability can simultaneously perform two sets of fast fourier transform (FFT) operations to process information from different subcarrier spacings. If the terminal device does not support this capability, then because it cannot process both types of SCS signals simultaneously, the terminal device does not expect to transmit signals such as the Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS), or receive signals such as the Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), Tracking Reference Signal (TRS), and Channel-State Information-Reference Signal (CSI-RS) used for channel quality indicator (CQI) feedback on all symbols of the currently measured SSB. In addition, due to synchronization and other operations, the above transmission is not allowed for the symbol immediately preceding or following these consecutive SSB symbols.
[0043] Measurement gap enhancement 1) Per-MG: A pre-configured MG that supports network control or terminal devices to activate or deactivate the MG based on certain conditions, such as during BWP handover.
[0044] 2) Multiple MGs (concurrent MG): Configure multiple MGs (with different patterns) for different reference signals (RS), including per-FR / per-UE, and configure different MG priorities.
[0045] 3) Network controlled small gap (NCSG) The purpose of the NCSG scheme is to reduce transmission interruptions caused by RRM measurements. It defines the NCSG pattern by defining the visible interruption length (VIL) and measurement length (ML). During the VIL, the terminal device does not perform uplink or downlink transmissions. During the ML, the terminal device does not expect to send PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS signals for CQI feedback on all symbols of the currently measured SSB. Furthermore, due to synchronization and other operations, the immediate preceding and following symbol of these consecutive SSB symbols is also not allowed to perform the above transmissions.
[0046] As can be seen from the preceding description, the RRM measurement process can cause service interruptions, resulting in significant transmission delays for the corresponding services, which cannot meet the low-latency requirements of certain services (such as XR services).
[0047] To address the aforementioned issues, the embodiments of this application will be described in detail below.
[0048] Example 1 Figure 2 This is a flowchart illustrating the wireless communication method provided in Embodiment 1 of this application. Figure 2 The method can be executed by a terminal device, such as the terminal device 120 mentioned above.
[0049] See Figure 2 In step S210, the terminal device performs a first operation. The first operation includes one or more of the following: discarding one or more measurement opportunities (dropping measurement opportunities can also be called ignoring measurement opportunities or deactivating measurement opportunities); determining that one or more measurement opportunities share time-domain resources with data transmission; and performing uplink / downlink data transmission during the time period corresponding to one or more measurement opportunities. The one or more measurement opportunities mentioned above are measurement opportunities used for RRM measurement. Embodiments of this application support data transmission during RRM measurement opportunities, thereby reducing data transmission latency and improving system throughput and capacity.
[0050] For RRM measurements based on measurement intervals, the time period corresponding to the measurement timing mentioned in the embodiments of this application can refer to the measurement interval. For RRM measurements without configured measurement intervals, the time period corresponding to the measurement timing mentioned in the embodiments of this application can refer to the time slot or symbol that will cause a data transmission interruption during the RRM measurement. For example, for NCSG, the time period corresponding to the measurement timing can be considered as the VIL that causes the data transmission interruption. For SSB-based measurement timing configuration (SMTC), the time period corresponding to the measurement timing can refer to the SSB time slot that causes the data interruption.
[0051] Furthermore, in some implementations, the time period corresponding to the measurement timing may also include a third time period before the measurement timing and / or a fourth time period after the measurement timing. Taking SMTC as an example, the time period corresponding to the measurement timing may include the SSB time slot that causes the data interruption and 1ms / Tms time before and after the SSB time slot.
[0052] Before executing step S210, the terminal device and the network device may exchange information / signaling to prepare for the execution of the first operation.
[0053] In some implementations, prior to step S210, the terminal device may receive first capability information sent by the network device. The first capability information indicates whether the network device supports the terminal device performing a first operation. For example, the method of scheduling uplink / downlink data during measurement as proposed in this application embodiment can be referred to as an enhanced scheduling mechanism; correspondingly, the first capability information can be used to indicate whether the network device supports this enhanced scheduling mechanism. Further, in some implementations, the first capability information may be associated with one or more of the following: band, band combination, carrier, BWP, intra-frequency band, and inter-frequency band.
[0054] In some implementations, prior to step S210, the terminal device may send second capability information to the network device. The second capability information indicates whether the terminal device is capable of performing the first operation. For example, the method of scheduling uplink / downlink data during measurement as proposed in this application embodiment can be referred to as an enhanced scheduling mechanism; correspondingly, the second capability information can be used to indicate whether the terminal device supports this enhanced scheduling mechanism. Further, in some implementations, the second capability information may be associated with one or more of the following: frequency band, frequency band combination, carrier, BWP, co-frequency band, and different-frequency band.
[0055] In some implementations, the terminal device and the network device can exchange service information before step S210. For example, the terminal device can report upstream service-related information to the network device, including service type (such as XR-related services), quality of service (QoS) requirements (latency requirements, etc.), data cycle, data arrival time, and arrival time jitter, etc.
[0056] In some implementations, before step S210, see [link to relevant documentation]. Figure 3 In step S310, the terminal device may first receive target information from the network device. This target information includes configuration information. The configuration information may include one or more of the following: first configuration information for configuring the terminal device to perform a first operation; second configuration information related to RRM measurement; third configuration information related to network device scheduling; fourth configuration information for configuring one or more measurement opportunities and time-domain resource sharing methods for data transmission; fifth configuration information related to the terminal device's data status reporting; and sixth configuration information for configuring the maximum number or maximum proportion of discardable measurement opportunities / slots.
[0057] The first configuration information can be referred to as the configuration information related to the enhanced scheduling mechanism. This first configuration information may include configurations for determining whether and which measurement timings to discard.
[0058] In some implementations, the first configuration information is used to configure a first time period. The first time period can be understood as the time period during which the enhanced scheduling mechanism is active. The first time period is used for the terminal device to perform a first operation. For example, the first configuration information can configure one or more of the following: the start time of the first time period, and the duration of the first time period. The first configuration information can configure the start time of the first time period. Alternatively, the start time of the first time period can also be determined during the actual interaction. The first configuration information can directly indicate the duration of the first time period, or it can be determined by configuring a first timer. For example, the timing duration of the first timer can be determined as the duration of the first time period. As an example, the first configuration information configures the start time + duration of the first time period. As another example, the first configuration information configures a first timer, and the runtime of the first timer is used as the aforementioned first time period.
[0059] As mentioned above, the first time period is used for the terminal device to perform the first operation. For example, the terminal device may discard all measurement opportunities within the first time period. Alternatively, if the measurement object associated with the measurement opportunity supports enhanced scheduling operations, the terminal device may discard such measurement opportunities. If a portion of a measurement opportunity is included within the first time period, that measurement opportunity may or may not be discarded.
[0060] In some implementations, the first configuration information can be configured with a second time period. This second time period is used by the terminal device to determine whether to perform the first operation; therefore, it can also be called the terminal device's decision time. For example, the second time period can include the first X time units of each measurement opportunity. The time unit mentioned here can be a slot, millisecond (ms), or symbol, where X is a positive integer greater than or equal to 1.
[0061] The length of the second time period can be fixed or associated with one or more of the following: the object being measured (or the target being measured); the frequency range; and the type of measurement, which includes intra-frequency measurements and / or inter-frequency measurements.
[0062] For example, for measurement object 1, the length of the second time period is value 1; for measurement object 2, the length of the second time period is value 2.
[0063] For example, for FR1, the length of the second time period is value 1; for measurement object 2, the length of the second time period is value 2.
[0064] For example, for same-frequency measurements, the length of the second time period is value 1; for different-frequency measurements, the length of the second time period is value 2.
[0065] In some implementations, the second configuration information mentioned above (configuration information related to RRM measurement) is used to configure one or more of the following: whether the measurement object corresponding to the RRM measurement supports the terminal device to perform the first operation (i.e., whether it supports the enhanced scheduling mechanism proposed in this application, i.e., not performing RRM measurement during the RRM measurement time, but performing uplink and downlink transmission); the priority of the measurement object corresponding to the RRM measurement; and the measurement threshold corresponding to the RRM measurement.
[0066] In some implementations, the measurement threshold corresponding to the RRM measurement is associated with one or more of the following (or, the measurement threshold corresponding to the RRM measurement is used to evaluate one or more of the following): the signal quality of the serving cell (such as the current cell); the signal quality of neighboring cells; the difference in signal quality between the serving cell and neighboring cells; the change in the signal quality of the serving cell; and the change in the signal quality of neighboring cells.
[0067] In some implementations, after configuring the above measurement thresholds, the terminal device can send the measurement results to the network device according to the measurement thresholds corresponding to the RRM measurement.
[0068] In some implementations, the third configuration information mentioned above (configuration information related to network device scheduling, or scheduling configuration) can be used to configure one or more of the following: whether network device scheduling is allowed within one or more measurement periods; and the priority of network device scheduling.
[0069] In some implementations, the fourth configuration information mentioned above is used to configure the time-domain resource sharing method between one or more measurement opportunities and data transmission. Taking the measurement opportunity as the measurement interval as an example, this fourth configuration information can be called measurement interval sharing information (Gap sharing). Furthermore, in some implementations, the fourth configuration information can be used to configure the sharing ratio between measurement opportunities and data transmission. For example, the fourth configuration information can indicate that the entire measurement opportunity is used for data transmission. Or, the fourth configuration information can indicate the proportion (e.g., percentage) of the measurement opportunity used for data transmission. Besides being configured through network devices, the time-domain resource sharing method between measurement opportunities and data transmission can also be a protocol-predefined default method. Alternatively, a default ratio, such as 50%, can be used between the time-domain resources of measurement opportunities and data transmission.
[0070] In some implementations, the fifth configuration information mentioned above (related to data status reporting by the terminal device) can configure data status reporting thresholds. These thresholds may include one or more of the following: a data volume threshold; a data priority threshold; and a data remaining latency threshold.
[0071] Accordingly, the terminal device can report data status to the network device based on the threshold configured in the fifth configuration information.
[0072] The configuration information of the network devices mentioned above can be common configuration information or associated with one of the following: frequency range (FR1 or FR2); measurement type, including same-frequency measurement and / or different-frequency measurement; measurement object; data priority (or data transmission priority); remaining latency of data; data volume; cell information; BWP.
[0073] See again Figure 2 The first operation mentioned in step S210 can be controlled (or triggered) by the network device, or it can be triggered autonomously by the terminal device according to certain conditions. The following describes these two possible triggering methods with reference to two embodiments.
[0074] Example 1.1: Network device triggers first operation In some implementations, see again Figure 3In step S310, the first operation is triggered based on a first command (or first signaling) in the target information sent by the network device. This first command, which may be called an ignore command, a discard command, or a deactivation command, is used to instruct the terminal device to discard one or more measurement opportunities. This first command may be carried in radio resource control (RRC) signaling, MAC control element (MAC CE), or downlink control information (DCI).
[0075] The first command can be a simple trigger command. Alternatively, the first command can also include some indicative information. For example, the first command can include initial information to determine when measurements need to be discarded or are permitted to be discarded.
[0076] For example, the first information includes one or more of the following: the timing of the measurement that needs to be discarded or is allowed to be discarded; the priority of the measurement object that needs to be discarded or is allowed to be discarded; and the priority of the data to be transmitted.
[0077] For example, if the first information indicates the priority of the measurement object that needs to be discarded or is allowed to be discarded, the terminal device can discard the measurement opportunity associated with the measurement object that is lower than that priority.
[0078] For example, if the first information indicates the priority of the data to be transmitted, the terminal device can discard measurement opportunities associated with measurement objects of lower priority.
[0079] Upon receiving the first command, the terminal device may discard measurement opportunities and / or perform uplink / downlink data transmission based on the first command. For example, the terminal device may discard one or more measurement opportunities within a first time period. This first time period may be determined based on the network device configuration and / or the time of receipt of the first command.
[0080] For example, if the start time and duration of the first time period are both based on network device configuration, the terminal device can determine the first time period based on the start time plus the duration configuration. Then, the terminal device can discard all allowable measurement opportunities within this first time period (or share the measurement opportunity with data transmission) and perform data transmission and reception according to the uplink and downlink scheduling of the network device.
[0081] For example, the start time of the first time period is determined based on the reception time of the first command (e.g., equal to the reception time of the first command), and the duration of the first time period is determined based on the network device configuration or the timing duration of the first timer. In this case, the terminal device can determine the first time period based on the reception time of the first command and the configuration information of the network device (or the timing duration of the first timer). Then, the terminal device can discard all allowable discardable measurement opportunities within the first time period (or share the measurement opportunities with data transmission), and perform data transmission and reception according to the uplink and downlink scheduling of the network device.
[0082] In some implementations, the terminal device can determine whether an RRM measurement is required for a given measurement timeframe (e.g., X time slots, milliseconds, or symbols prior to each measurement timeframe) based on a received first command. If no RRM measurement is required, the terminal device can perform uplink and downlink transmissions during that measurement timeframe. For example, the terminal device can determine whether uplink and downlink scheduling exists in the following measurement timeframe based on instructions from the network device. If uplink and downlink scheduling exists, the terminal device does not need to perform RRM measurement but can instead perform uplink and downlink transmissions.
[0083] In some implementations, if the terminal device performs uplink transmission during measurement, it can send corresponding uplink data according to the network device's scheduling configuration. For example, the scheduling configuration mentioned here may include one or more of the following: priority configuration for uplink transmissions scheduled by the network device, logical channel configuration, and data remaining delay requirement configuration.
[0084] In some implementations, if the terminal device performs downlink transmission during measurement, the method by which the terminal device listens to the downlink transmission can be determined based on the network implementation.
[0085] In some implementations, before executing step S210, the terminal device may send second information to the network device. This second information is used to request the network device to perform the first operation. This second information may be condition-triggered. For example, the second information may be triggered based on a first condition, which is associated with one or more of the following: whether the network device supports the terminal device performing the first operation; the priority of one or more measurement opportunities; the priority of the data to be transmitted; the scheduling method for the data to be transmitted, including scheduling based on configuration authorization and / or scheduling based on dynamic authorization; the scheduling priority of the network device; the remaining delay of the data to be transmitted; the coverage condition information of the terminal device; the transmission type of the data to be transmitted, including new transmission and / or retransmission; whether the maximum number of discardable measurement opportunities / slots (slots used for RRM measurement) has been exceeded; and whether the maximum proportion of discardable measurement opportunities / slots (slots used for RRM measurement) has been exceeded.
[0086] Whether the network device mentioned above supports the terminal device to perform the first operation can also be understood as whether the network device supports the enhanced scheduling method proposed in the embodiments of this application. Whether the network device supports the enhanced scheduling method can be determined by the network device sending capability information indication, or by determining whether the network device has configured configuration information related to the enhanced scheduling method.
[0087] The priority of one or more measurement events mentioned above can be determined, for example, based on the priority (or priority configuration) of the measurement object associated with the measurement event.
[0088] The priority of the data to be transmitted (sent / received) mentioned above can be determined, for example, based on the highest (or lowest) priority of the data in the buffer. Alternatively, it can be determined based on the priority of the logical channel with the least (or most) remaining delay.
[0089] The remaining delay of the data to be transmitted mentioned above can be determined based on the PDB of the data to be transmitted, the delay state (DS), and the discard timer.
[0090] The priority of the data to be transmitted mentioned above can be determined based on one or more of the following: the highest priority of the data to be transmitted; the priority of the logical channel with the least remaining delay.
[0091] The coverage condition information mentioned above can be determined based on one or more of the following: the signal quality of the serving cell; the signal quality of neighboring cells; changes in the signal quality of the serving cell; changes in the signal quality of neighboring cells; and the difference in signal quality between the serving cell and neighboring cells.
[0092] Example 1.2: Terminal device autonomously triggers the first operation In some implementations, the first operation mentioned in step S210 can be determined based on a second condition. That is, if the second condition is met, the terminal device can trigger the first operation autonomously.
[0093] In some implementations, the second condition is associated with one or more of the following: whether the network device supports the terminal device performing the first operation; the priority of one or more measurement opportunities; the priority of the data to be transmitted; the scheduling method of the data to be transmitted, including scheduling based on configuration authorization and / or scheduling based on dynamic authorization; the scheduling priority of the network device; the remaining delay of the data to be transmitted; the coverage condition information of the terminal device; the transmission type of the data to be transmitted, including new transmission and / or retransmission; whether the maximum number of disposable measurement opportunities / slots (slots used for RRM measurement) has been exceeded; whether the maximum proportion / number of disposable measurement opportunities / slots (slots used for RRM measurement) has been exceeded.
[0094] Whether the network device mentioned above supports the terminal device to perform the first operation can also be understood as whether the network device supports the enhanced scheduling method proposed in the embodiments of this application. Whether the network device supports the enhanced scheduling method can be determined by the network device sending capability information indication, or by determining whether the network device has configured configuration information related to the enhanced scheduling method.
[0095] The priority of one or more measurement events mentioned above can be determined, for example, based on the priority (or priority configuration) of the measurement object associated with the measurement event.
[0096] The priority of the data to be transmitted (sent / received) mentioned above can be determined, for example, based on the highest (or lowest) priority of the data in the buffer. Alternatively, it can be determined based on the priority of the logical channel with the least (or most) remaining delay.
[0097] The remaining delay of the data to be transmitted mentioned above can be determined based on the PDB of the data to be transmitted, the delay state (DS), and the discard timer.
[0098] The priority of the data to be transmitted mentioned above can be determined based on one or more of the following: the highest priority of the data to be transmitted; the priority of the logical channel with the least remaining delay.
[0099] The coverage condition information mentioned above can be determined based on one or more of the following: the signal quality of the serving cell; the signal quality of neighboring cells; changes in the signal quality of the serving cell; changes in the signal quality of neighboring cells; and the difference in signal quality between the serving cell and neighboring cells.
[0100] For example, the second condition includes one or more of the following: the coverage condition indicated by the coverage condition information satisfies the third condition; the priority of one or more measurement times (which may be determined based on the lowest or highest priority of the respective priorities of one or more measurement times) is less than or equal to the priority of the data to be transmitted.
[0101] For example, the second condition includes one or more of the following: the coverage condition indicated by the coverage condition information meets the third condition; the priority of the data to be transmitted is greater than or equal to the second priority.
[0102] In some implementations, the terminal device can determine whether an RRM measurement is required for a given measurement timeframe (e.g., X time slots, milliseconds, or symbols prior to each measurement timeframe) in a second time period before the measurement timeframe. If no RRM measurement is required, the terminal device can perform uplink and downlink transmissions during that measurement timeframe. For example, the terminal device can determine whether uplink and downlink scheduling exists in the next measurement timeframe based on instructions from the network device. If uplink and downlink scheduling exists, the terminal device does not need to perform RRM measurement but can instead perform uplink and downlink transmissions.
[0103] In some implementations, before the terminal device performs the first operation, it may send third information to the network device. This third information is used to indicate to the terminal device that it has determined, is preparing for, or is about to perform the first operation. This third information can be called uplink indication information. It can be carried in RRC, MAC CE, or PUCCH.
[0104] The third message can be sent voluntarily by the terminal device or based on a request from the network device. For example, before sending the third message to the network device, the terminal device receives a fourth message from the network device. The fourth message is used to request the terminal device to determine whether the first operation can be performed. This fourth message can be carried in RRC, MACCE, or PDCCH.
[0105] If the terminal device needs to perform uplink transmission during measurement, it can carry third-party information in the MAC CE or PUCCH. The MAC CE can be a buffer status report (BSR) or a delay status report (DSR). Furthermore, the MAC CE or PUCCH is also used to indicate one or more measurement objects associated with a measurement time.
[0106] To facilitate understanding, the following examples, which illustrate the judgment of the second condition and the behavior of the terminal device, will be used to explain the process in more detail, taking downlink and uplink transmissions at the time of measurement.
[0107] For downlink transmission Dynamic scheduling: If the terminal device determines that data reception can proceed based on the second condition mentioned above, at least X milliseconds / symbol / time slot position before the measurement time, then the terminal device sends an uplink indication to the network (via RRC / MAC CE / PUCCH). This determination and uplink indication can be based on network requests (RRC / MAC CE / PDCCH).
[0108] For example, network devices can indicate the desired location and priority of downlink transmission in the request information (corresponding to the fourth information mentioned above). If the downlink transmission location overlaps with the measurement timing, the terminal device determines whether the above coverage condition information is met. If the coverage condition information is met, it further determines whether to perform measurement or data reception based on the priority information of data transmission and measurement timing. For example, priority thresholds can be configured for measurement timing and data transmission respectively. If RRM measurement < priority 1; and / or data transmission > priority 2, the second condition can be considered met. Alternatively, the priority of measurement timing can be directly compared with the priority of data transmission; if the priority of measurement timing < data transmission priority, the second condition can be considered met. If there are multiple measurement timings, the highest priority among the priorities corresponding to each of the multiple measurement timings can be taken, and the highest priority can be compared with the data transmission priority.
[0109] Non-dynamic scheduling: Similar to dynamic scheduling, the difference is that the terminal device can determine downlink transmission location and other information directly based on the semi-static transmission configuration, without relying on requests from the network device. When the second condition mentioned above is met, the terminal device can indicate to the network device that downlink scheduling is possible, and can further indicate the scheduling resource location / window. After receiving the indication from the terminal device, the network device will schedule downlink transmission at the corresponding location.
[0110] For uplink transmission Dynamic scheduling: If, at least X milliseconds / symbol / time slot before the measurement time, the terminal device determines that data transmission is possible based on the second condition mentioned above, and the terminal device's buffer contains data, then the terminal device can send an uplink indication to the network (via RRC / MAC CE / PUCCH). This determination and uplink indication can be based on network requests (RRC / MAC CE / PDCCH).
[0111] For example, if the terminal device has data to be sent in its buffer, but the terminal device needs to perform RRM measurement immediately, the terminal device determines whether the above coverage condition information is met. If the coverage condition information is met, it further determines whether to perform measurement or data reception based on the priority information of data transmission and measurement timing. For example, priority thresholds can be configured for measurement timing and data transmission respectively. If RRM measurement < priority 1; and / or data transmission > priority 2, then the second condition can be considered met. Alternatively, the priority of measurement timing can be directly compared with the priority of data transmission; if the priority of measurement timing < the priority of data transmission, then the second condition can be considered met. If there are multiple measurement timings, the highest priority among the priorities corresponding to each of the multiple measurement timings can be taken, and the highest priority can be compared with the data transmission priority.
[0112] If the terminal device determines that data transmission is to proceed, it sends an indication message (corresponding to the third message mentioned earlier) to the network. This indication message can, for example, use an enhanced BSR / DSR MAC CE. Exemplarily, an indication of the timing of measurement transmission can be added to the BSR / DSR MAC CE, and it can further indicate the correlation between the timing of measurement and the object being measured. Alternatively, the indication message can use a new signaling indication.
[0113] Non-dynamic scheduling: Similar to dynamic scheduling, the difference is that the terminal device can determine the uplink transmission location and other information based on the semi-static transmission configuration, so that it can directly use the corresponding resources to perform uplink transmission when the second condition is met.
[0114] In some implementations, if the terminal device performs uplink transmission during measurement, it can send corresponding uplink data according to the network device's scheduling configuration. For example, the scheduling configuration mentioned here may include one or more of the following: priority configuration for uplink transmissions scheduled by the network device, logical channel configuration, and data remaining delay requirement configuration.
[0115] In some implementations, if the terminal device performs downlink transmission during measurement, the method by which the terminal device listens to the downlink transmission can be determined based on the network implementation.
[0116] It should be noted that the overlap between the measurement timing and the network device scheduling mentioned above can be complete or partial. When determining whether there is an overlap, in addition to judging the time slot or symbol where the measurement timing and scheduling are located, we can also consider the M (M is a positive integer greater than or equal to 1) time slots / symbols before and / or after the measurement timing (equivalent to considering the processing time of the terminal device).
[0117] As mentioned earlier, whether the terminal device performs the first operation can be based on the control of the network device (hereinafter referred to as the first processing method), or it can be performed autonomously by the terminal device (hereinafter referred to as the second processing method). These two processing methods can coexist. That is, the communication system can support both processing methods simultaneously. In actual use, the specific processing method used can be flexibly selected according to actual needs. For example, the processing method can be determined based on the control of the network device. The network device can comprehensively decide which processing method to use based on whether it supports the first processing method and / or whether the terminal device supports the second processing method. For example, downlink transmission can use the first processing method, while uplink transmission can use the second processing method. For example, dynamic scheduling can use the first processing method, while non-dynamic scheduling (scheduling based on configuration authorization) can use the second processing method. For example, new data transmission can use the first processing method, while data retransmission can use the second processing method.
[0118] The embodiments of this application are described in more detail below with specific examples. It should be noted that... Figures 4 to 5 The examples provided are merely to help those skilled in the art understand the embodiments of this application, and are not intended to limit the embodiments of this application to the specific numerical values or specific scenarios illustrated. Figures 4 to 5 The examples are obviously subject to various equivalent modifications or changes, and such modifications or changes also fall within the scope of the embodiments of this application.
[0119] See Figure 4 In step S410, the preparation phase, the terminal device and network device can collect one or more of the following: capability information, service information, configuration information, measurement reporting information, and data status. Detailed descriptions are provided above and will not be repeated here.
[0120] In step S420, the network device sends a drop measurementoccasion command to the terminal device. This command can be RRC signaling, MAC CE, or DCI.
[0121] In step S430, the terminal device discards the measurement opportunity.
[0122] In step S440, the terminal device performs uplink / downlink transmission based on the scheduling of network devices within the discarded measurement time.
[0123] See Figure 5 In step S510, the preparation phase, the terminal device and network device can collect one or more of the following: capability information, service information, configuration information, measurement reporting information, and data status. Detailed descriptions are provided above and will not be repeated here.
[0124] In step S520, the terminal device determines whether the condition is met. This condition corresponds to the second condition mentioned above, which can be described in detail above.
[0125] In step S530, if the second condition is met, the measurement opportunity is discarded.
[0126] In step S540, the terminal device reports a report to the network device about the timing of the dropped measurement.
[0127] In step S550, the terminal device performs uplink / downlink transmission based on the scheduling of network devices within the discarded measurement time.
[0128] Example 2 Figure 6 This is a flowchart illustrating the wireless communication method provided in Embodiment 2 of this application. Figure 6 The method can be executed by a terminal device, such as the terminal device 120 mentioned above.
[0129] See Figure 6 In step S610, if the first condition is met, the terminal device adjusts the first configuration information (RRM measurement configuration). The first configuration information is used for RRM measurement. That is to say, the first configuration information in this embodiment is not fixed, but can be flexibly adjusted according to the conditions, thereby reducing data transmission interruptions by configuring / adjusting RRM measurement-related configurations.
[0130] In some implementations, the first condition is associated with one or more of the following: the reliability requirements of the data to be transmitted; the latency requirements of the data to be transmitted; the remaining latency of the data to be transmitted; the mobility status of the terminal device; and the location of the terminal device in the serving cell.
[0131] The reliability requirements for the data to be transmitted could be, for example, whether there is a need for highly reliable and / or low-latency data (such as XR data). If the data to be transmitted has a need for highly reliable and / or low-latency data, then a smaller measurement window (or a smaller data transmission interruption duration) can be used.
[0132] The latency requirement for the data to be transmitted can, for example, measure the urgency of the data. For instance, if the latency of the data to be transmitted is less than a certain threshold, the first configuration information can be adjusted. If the urgency of the data to be transmitted is high, a shorter measurement interval or a longer measurement period (or a shorter data transmission interruption duration) can be used.
[0133] The mobility status of the aforementioned terminal device can be used to determine whether the terminal device is in a low mobility state. If the terminal device is in a low mobility state, the first configuration information can be adjusted. Whether the terminal device is in a low mobility state can be determined based on whether the measured changes in the signal quality of the serving cell and / or neighboring cells are less than a certain threshold. If the terminal device is in a low mobility state, a smaller measurement interval (or a smaller data transmission interruption duration) can be used.
[0134] The location of the terminal device within the serving cell can refer to whether the terminal device is at the cell edge. For example, if the terminal device is at the cell edge, the first configuration information may or may not be adjusted. Whether the terminal device is at the cell edge can be determined based on the signal quality of the serving cell, the signal quality of neighboring cells, and / or the difference in signal quality between the serving cell and neighboring cells. For example, if the signal quality of the serving cell is higher than a certain threshold, it indicates that the terminal device is not at the cell edge. Similarly, if the signal quality of a neighboring cell is lower than a certain threshold, it indicates that the terminal device is not at the cell edge. Furthermore, if the signal quality of the serving cell is higher than the signal quality of a neighboring cell by a certain threshold, it indicates that the terminal device is not at the cell edge. If the terminal device is not at the cell edge, a smaller measurement opportunity (or a smaller data transmission interruption duration) can be used.
[0135] The first configuration information can be adjusted under the control of the network device or by the terminal device itself. These two implementation methods are described below.
[0136] Example 2.1: Adjusting RRM Measurement Configuration under Network Device Control In embodiment 2.1, step S610 may include: the terminal device sending first information to the network device. The first information is used to indicate that a first condition is met (or the first condition has changed). This first information may be carried in RRC, MAC CE, or PUCCH.
[0137] After receiving the first message, see Figure 7 In step S710, the network device may send second information to the terminal device. The second information is used to: reconfigure the first configuration information; or, instruct the terminal device to switch from the first configuration information to the second configuration information.
[0138] The first and second configuration information mentioned above are both configuration information used for RRM measurement, referred to as RRM measurement configuration. For example, network devices can pre-configure multiple RRM measurement configurations for terminal devices and switch to different configurations under different circumstances (based on the reports from the terminal devices).
[0139] In some implementations, the second information can be carried in RRC, MAC CE, or DCI.
[0140] Example 2.2: Terminal device autonomously adjusts RRM measurement configuration In embodiment 2.2, step S610 may include: the terminal device adjusting the first configuration information according to the first parameter. The first parameter is determined based on the configuration information of the network device. For example, the first parameter may relax the RRM measurement configuration (i.e., the first configuration information) by a certain multiple / value, such as lengthening the measurement period by a factor of Y. Or, lengthening the measurement period by X time slots. X and / or Y mentioned here can be the first parameter. The first parameter may be configured by the network device. The first parameter may be a configuration parameter related to the measurement result / remaining delay. In some implementations, the first parameter is related to the measurement result. For example, if the measurement result indicates that the serving cell signal quality is higher than the threshold interval 1, then the value of the first parameter is 1; if the measurement result indicates that the serving cell signal quality is higher than the interval 2, then the value of the first parameter is 2. In other implementations, the first parameter is related to the remaining delay of the data to be transmitted. For example, if the remaining delay of the transmitted data belongs to interval 1, then the value of the first parameter is 1; if the remaining delay of the transmitted data belongs to interval 2, then the value of the first parameter is 2. Alternatively, in some implementations, the remaining delay and the measurement result may be considered together.
[0141] Alternatively, in embodiment 2.2, step S610 may include: the terminal device autonomously switching from the first configuration information to the second configuration information. Both the first and second configuration information are configuration information used for RRM measurement, referred to as RRM measurement configuration. For example, the network device may pre-configure multiple sets of RRM measurement configurations for the terminal device and switch to different configurations under different circumstances (based on the terminal device's reporting).
[0142] In some implementations, the multiple RRM measurement configurations can be associated with one or more of the following: the measurement results of the RRM measurement; the remaining delay of the data packet to be transmitted.
[0143] In some implementations, if the terminal device adjusts the first configuration information, the terminal device can send second information to the network device. The second information is used to indicate the result of the adjustment of the first configuration information.
