Description

Technical Field

[0001] This disclosure relates generally to wireless communications, and more particularly to the measurement of the quality of wireless links in wireless communication networks. Background Technology

[0002] In existing wireless communication systems, Radio Link Failure (RLF) detection and recovery procedures are used to maintain the wireless link between the Wireless Network Access Node (WANN) and the User Equipment (UE). At the beam level, Beam Failure Detection (BFD) and Beam Failure Recovery (BFR) are used to maintain proper downlink (DL) beams. To perform RLF detection and beam failure detection, the UE is configured with a reference signal. Generally, the WANN periodically transmits the reference signal to the UE, and the UE must measure the periodically transmitted reference signal to determine the quality of the wireless link between the UE and the WANN, which inevitably consumes the UE's power. Summary of the Invention

[0003] This disclosure relates to methods, systems, and apparatus for managing the quality measurement of wireless links between wireless network access nodes and user equipment, in connection with wireless communication.

[0004] In one embodiment, a method for managing wireless link quality measurements by a user equipment (UE) is disclosed. The method can be performed at the UE. The method may include obtaining information about adjusting an indication period. The indication period may represent a time interval during which a wireless link quality indication is sent to the upper layer of the UE. The wireless link quality indication may indicate the quality of the wireless link between the UE and a wireless access network node. The method may further include determining whether to adjust the indication period based on the information.

[0005] In another embodiment, a device for wireless communication may include a memory storing instructions and a processing circuitry system communicating with the memory. When the processing circuitry system executes the instructions, the processing circuitry system is configured to perform the methods described above.

[0006] In another embodiment, a computer-readable medium includes instructions that, when executed by a computer, cause the computer to perform the methods described above.

[0007] The above and other aspects and their implementations will be described in more detail below in the accompanying drawings, description and claims. Attached Figure Description

[0014] The techniques and examples of implementations and / or embodiments in this disclosure can be used to improve the performance of wireless communication systems. The term "exemplary" is used to mean "example" and, unless otherwise stated, does not imply an ideal or preferred example, implementation, or embodiment. Section headings used in this disclosure are for facilitating understanding and not to limit the techniques disclosed in a section to the corresponding section. However, it should be noted that these implementations can be embodied in a variety of different forms, and therefore, the covered or claimed subject matter is intended to be construed as not being limited to any of the embodiments set forth below. It should also be noted that implementations can be embodied as methods, apparatus, components, or systems. Accordingly, embodiments of this disclosure can take the form of, for example, hardware, software, firmware, or any combination thereof.

[0015] A wireless access network provides network connectivity between user equipment and information or data networks, such as voice or video communication networks, the Internet, etc. Example wireless access networks may be based on cellular technology, and may further be based on technologies and / or formats such as 4G Long Term Evolution (LTE), 5G, and / or New Radio (NR). Figure 1An example system diagram of a wireless communication network 100, including a user equipment (UE) 102 and a wireless access network node (WANN) 104, is shown according to various embodiments. The UE 102 may include, but is not limited to, a mobile phone, smartphone, tablet computer, laptop computer, smart electronic device or appliance (including air conditioner, television, refrigerator, oven, etc.), or other device capable of wireless communication over a network. The UE 102 may include a transceiver circuitry 106 coupled to an antenna 108 to enable wireless communication with the wireless access network node 104. The transceiver circuitry 106 may also be coupled to a processor 110, which may also be coupled to a memory 112 or other storage device. The memory 112 may store instructions or code therein that, when read and executed by the processor 110, cause the processor 110 to implement the various methods described herein.

[0016] Similarly, wireless access network node 104 may include a base station or other wireless network access point capable of wirelessly communicating with one or more UEs via a network. For example, in various embodiments, wireless access network node 104 may include a 5G New Radio (NR) base station, a 5G central unit base station, or a 5G distributed unit base station, a 5G core station, or an application server. Each type of these wireless access network nodes may be configured to perform a corresponding set of wireless network functions. The sets of wireless network functions between different types of wireless access network nodes may not be the same. However, the sets of wireless network functions between different types of wireless access network nodes may overlap functionally. Wireless access node 104 may include a transceiver circuitry 114 coupled to an antenna 116 to enable wireless communication with UE 102, the antenna may include an antenna tower 118 in various ways. The transceiver circuitry 114 may also be coupled to one or more processors 120, which may also be coupled to a memory 122 or other storage device. The memory 122 may store instructions or code therein that, when read and executed by the processor 120, cause the processor 120 to implement the various methods described herein.

[0017] For simplicity and clarity, only one WANN and one UE are shown in the wireless communication network 100. It will be understood that there can be one or more WANNs in the wireless communication network, and each WANN can serve one or more UEs simultaneously.

[0018] Evolved next-generation wireless communication networks provide discontinuous reception for user equipment (UEs). Discontinuous reception is a method used in wireless communication to conserve UE battery power. For example, the UE and the network can negotiate a phase in which data transmission occurs. During other times, the UE can turn off its receiver and enter a low-power state. One objective of this disclosure is to dynamically adjust an indication period that can represent the time interval used to measure the quality of the wireless link between the UE and the WANN for RLF detection and beam fault detection when DRX is applied to the wireless link between the UE and the WANN. Reference Figure 6 The DRX period can include an on duration segment and an off duration segment. The UE can monitor the Physical Downlink Control Channel (PDCCH) during the on duration segment, and does not need to monitor the PDCCH during the off duration segment.

[0019] Figure 2 An example implementation 200 for adjusting the indicated time period is shown. For example, refer to... Figure 1 and Figure 2 Describes various operations such as the user equipment adjustment indication period of UE 102.

[0020] UE 102 can obtain information about adjusting the indication period (210). The indication period can represent a time period. During each such time period, a radio link quality indication can be transmitted from a lower layer, such as the physical layer, of UE 102 to an upper layer, such as the MAC layer. The radio link quality indication can indicate the quality of the radio link between the user equipment and the radio access network node. For example, the radio link quality indication can indicate whether the actual measurement result is higher or lower than a predetermined threshold. The actual measurement result can indicate the result of measuring the quality of the radio link between UE 102 and WANN 118. UE 102 can decide whether to adjust the indication period based on the obtained information (220). Adjusting the indication period can extend or shorten the indication period. When the indication period is extended, the radio link quality measurement is relaxed.

[0021] In one implementation, UE 102 may receive information from WANN 118 regarding the adjustment of the indication period. This information may include an indication of whether UE 102 is permitted to adjust the indication period. WANN 118 may transmit the information via Radio Resource Control (RRC) signaling, Media Access Control (MAC) Control Element (CE) signaling, or Downlink Control Information (DCI) signaling. When using MAC CE signaling, the MAC CE may include a Channel State Information Reference Signal (CSI-RS) identifier (ID), serving cell ID, Bandwidth Part (BWP) ID, Synchronization Signal Block (SSB) ID, an offset parameter for adjusting the indication period (described in detail later), and an indication of the measurement mode to be used (e.g., relaxed or non-relaxed). When using DCI signaling, the DCI may include code points representing the BWP ID, the serving cell ID, the CSI-RS, the SSB, the offset parameter, and an indication of the measurement mode to be used.

[0022] In one implementation, UE 102 may receive information from WANN 118 regarding the adjustment indication period. This information may include an indication of whether UE 102 is permitted to adjust the indication period. WANN 118 may transmit the information via Radio Resource Control (RRC) signaling, Media Access Control (MAC) Control Element (CE) signaling, or Downlink Control Information (DCI) signaling. In one implementation, a combination of the aforementioned information (i.e., RRC, MAC CE, DCI) may be used. For example, offset parameters for adjusting the indication period may be sent from WANN 118 to UE 102 via RRC signaling. An adjustment indication may be sent from WANN 118 to UE 102 via MAC CE signaling or DCI signaling. In this case, MAC CE may include a Channel State Information Reference Signal (CSI-RS) identifier (ID), serving cell ID, bandwidth portion (BWP) ID, synchronization signal block (SSB) ID, and an indication of the measurement mode to be used (e.g., relaxed or non-relaxed). When using DCI signaling, DCI may include code points representing BWP ID, code points representing serving cell ID, code points representing CSI-RS, code points representing SSB, and code points indicating the measurement mode to be used.

[0023] In another implementation, UE 102 may read information about adjusting the indication period from its memory. This information may include predetermined rules for determining whether to adjust the indication period based on a specific event. For example, the specific event may indicate the receipt of a wake-up signal (WUS). If the WUS does not indicate that UE 102 wakes up within the associated DRX cycle, UE 102 may decide to extend the indication period. If the WUS indicates that UE 102 wakes up within the associated DRX cycle and the indication period has been adjusted to an extended indication period for relaxation measurements, UE 102 may restore the indication period from the extended indication period. For example, the indication period may return to the original indication period before adjustment. Alternatively, the indication period may return to a period shorter than the extended indication period.

[0024] Additionally or alternatively, specific events may include measured metrics of a reference signal, which can indicate the quality of the radio link between UE 102 and WANN 118. Measured metrics of the reference signal may include, for example, reference signal received power, signal-to-interference-plus-noise ratio, and path loss. If the measured metric is greater than or equal to a predetermined threshold, UE 102 may decide to extend the indication period. If the measured metric is less than the predetermined threshold and the indication period has already been adjusted to the extended indication period, UE 102 can restore the indication period from the extended indication period. For example, the indication period may return to the original indication period before adjustment. Alternatively, the indication period may return to a period shorter than the extended indication period.

[0025] Additionally or alternatively, if UE 102 can be configured with DRX for the radio link between UE 102 and WANN 118, specific events may include the state of a monitoring timer related to monitoring the quality of the radio link. The monitoring timer may include, for example, a T310 timer and a beam failure detection timer (e.g., beamFailureDetectionTimer). The T310 timer can be used in radio link failure (RLF) measurements. For example, the T310 timer may be started upon receiving an N310 continuous desynchronization indication and stopped upon receiving an N311 continuous synchronization indication. An RLF may be triggered when the T310 timer expires. The beamFailureDetectionTimer can be used in beam failure (BFR) measurements. For example, the MAC entity of UE 102 may be configured with beamFailureInstanceMaxCount and beamFailureDetectionTimer for each serving cell including WANN 118. Upon receiving a beam failure indication, UE 102 may increment BFI_COUNTER by 1 and start or restart the beamFailureDetectionTimer. If beamFailureDetectionTimer expires, UE 102 can set BFI_COUNTER to zero. If BFI_COUNTER reaches the maximum number beamFailureInstanceMaxCount, UE 102 can trigger BFR.

[0026] If the status of the monitoring timer indicates that the monitoring timer is stopped, UE 102 may decide to extend the indication period. If the status of the monitoring timer indicates that the monitoring timer is running, UE 102 may restore the indication period from the extended indication period. For example, the extended indication period may return to the original indication period before the adjustment. Alternatively, the indication period may return to a period shorter than the extended indication period.

[0027] Additionally or alternatively, if UE 102 is configured with DRX for the radio link between UE 102 and WANN 118, specific events may include the state of UE 102. If the state of UE 102 indicates that UE 102 is inactive, UE 102 may decide to extend the indicated period. If the state of UE 102 indicates that UE 102 is active, UE 102 may resume the indicated period from the extended indicated period. For example, the indicated period may return to the original indicated period before adjustment. Alternatively, the indicated period may return to a shorter period than the extended indicated period.

[0028] Additionally or alternatively, when UE 102 is performing relaxed measurements for BFR and RLF (i.e., using an extended indication period), UE 102 may determine whether certain mobility-related events have been triggered. If so, UE 102 may resume the indication period from the extended indication period. Events may include at least one of the following: (1) Event A2: Service becomes inferior to a threshold; (2) Event A3: Neighboring cells become offset better than SpCe ll; (3) Event A4: Neighboring cells become better than a threshold; (4) Event A5: SpCe ll becomes inferior to a threshold, while neighboring cells become better than another threshold; (5) Event B1: Inter-RAT neighboring cells become better than a threshold; (6) Event B2: PCe ll becomes inferior to a threshold, while inter-RAT neighboring cells become better than another threshold; (7) Event I: Interference becomes higher than a threshold.

[0029] Additionally or alternatively, if the serving cell covering UE 102 is a dormant serving cell or the active BWP at that serving cell is a dormant BWP, UE 102 will perform relaxed measurements for said serving cell. In some implementations, the dormant serving cell is SCe 11 or the dormant BWP is a BWP in which UE 102 only performs measurements (CSI-RS or SSB) but does not monitor transmissions on PDCCH, Physical Downlink Shared Channel (PDSCH), or Uplink Shared Channel and PUCCH.

[0030] refer to Figure 2 If UE 102 decides to adjust the indication period at step 220, UE 102 can adjust the indication period (230) based on the information obtained at step 210. In one implementation, the information may include, for example, an offset parameter for adjusting the indication period. For example, the offset parameter may be received from WANN 118 via MAC CE signaling, DCI signaling, or Radio Resource Control (RRC) signaling. For another example, the offset parameter may be configured to UE 102 at the granularity of cell group or cell. For another example, the offset parameter may be predefined, for example, in the technical specifications of a wireless communication protocol. The offset parameter may include, for example, a first coefficient for the DRX period, a second coefficient for the shortest period of time from WANN 118 for receiving a reference signal to measure the quality of the radio link, a third coefficient for the longest period of time from WANN 118 for receiving the reference signal, and a period value with a specified time unit. The time unit may include, for example, milliseconds, time slots, symbols, and subframes.

[0031] When the offset parameter includes a first coefficient representing the DRX period, UE 102 can adjust the indication period to be equal to the maximum value of the shortest period of the reference signal and the DRX period multiplied by the first coefficient. Alternatively, when the offset parameter includes a second coefficient representing the shortest period of the reference signal received from WANN 118, UE 102 can adjust the indication period to be equal to the maximum value of the DRX period and the shortest period of the reference signal multiplied by the second coefficient. Alternatively, when the offset parameter includes a third coefficient representing the longest period of the reference signal received from WANN 118, UE 102 can adjust the indication period to be equal to the maximum value of the DRX period and the longest period of the reference signal multiplied by the third coefficient. Alternatively, when the offset parameter includes a period value, UE 102 can adjust the indication period to be equal to the maximum value of the shortest period of the reference signal, the DRX period, and the period value. The first coefficient, second coefficient, third coefficient, and time period value can be predefined, for example, in technical specifications such as wireless communication protocols, or dynamically received from WANN 118, for example, via RRC signaling, DCI signaling, or MAC CE signaling.

[0032] With the indication period extended, UE 102 can reduce the frequency of radio link quality measurements. This relaxation of radio link quality measurements may undesirably affect UE 102's use of the T310 timer for radio link failure detection and the beamfailuredetectionTimer for beam failure detection. Figure 3 This illustrates radio link fault detection under relaxed measurement conditions. As shown in the figure, during the period when the T310 timer is running, UE 102 might expect to receive four consecutive synchronization indications. Otherwise, UE 102 might trigger a radio link fault. However, due to relaxed measurement, UE 102 fails to perform a sufficient number of radio link quality measurements during the T310 timer's running period, resulting in fewer than four consecutive synchronization indications. For example, UE 102 might only receive three consecutive synchronization indications during the T310 timer's operation. As a result, although the radio link can function well with good quality, UE 102 might trigger a falsely detected radio link fault.

[0033] Figure 4Beam fault detection under relaxed measurement conditions is illustrated. Upon receiving a beam fault indication, UE 102 can increment BFI_COUNTER by 1 and start or restart beamFailureDetectionTimer. When beamFailureDetectionTimer expires, UE 102 can set BFI_COUNTER to zero. UE 102 can trigger a beam fault when BFI_COUNTER reaches its maximum value, beamFailureInstanceMaxCount. However, relaxed measurements can present sparse beam fault indications during the operation of beamFailureDetectionTimer. The expiration of beamFailureDetectionTimer resets BFI_COUNTER. Therefore, even if a beam fault occurs, it is difficult for BFI_COUNTER to reach beamFailureInstanceMaxCount and trigger a beam fault.

[0034] To address the negative impact of relaxed measurements on radio link failure detection (RLF) and beam failure detection (BFD), UE 102 can be configured with a mechanism to pause the T310 timer and beamFailureDetectionTimer when using the indication period for RLF and BFD measurements. Alternatively, UE 102 can be configured with two monitoring timers, such as two T310 timers or two beamFailureDetectionTimers. The two sets of monitoring timers can be used separately for relaxed measurements (i.e., using the original indication period) and non-relaxed measurements (i.e., using the extended indication period).

[0035] For example, when using the original indication period (i.e., non-relaxed measurement), UE 102 can utilize a first monitoring timer. When using an extended indication period (i.e., measurement relaxation), UE 102 can utilize a second monitoring timer. WANN118 can configure the second monitoring timer and send it to UE 102, for example, via RRC signaling.

[0036] When UE 102 starts measuring the radio link quality for an extended indicated period of time while the first monitoring timer is running, UE 102 may stop the first monitoring timer and switch to using the second monitoring timer to monitor the radio link quality.

[0037] Furthermore, when UE 102 decides to stop measuring the radio link quality during the extended indicated period and revert to measuring the radio link quality during the original indicated period, UE 102 can restart the first monitoring timer. Simultaneously, UE 102 can stop using the second monitoring timer and switch back to using the first monitoring timer.

[0038] A DRX group may include a set of DRX configuration parameters. A user equipment such as UE 102 may maintain multiple DRX groups, which may be used by different cells serving UE 102. It is possible that multiple cells serving UE 102 may use the same DRX group. Because multiple DRX groups are maintained, UE 102 may have to determine which DRX group(s) the wake-up signal can be applied to. In one implementation, the WUS signal is used to indicate whether to start the drx-ondurationTimer for the current DRX period. Figure 5 An example implementation 500 for applying a wake-up signal to a DRX group is shown. For example, refer to... Figure 1 and Figure 5 Describes the various operations of UE 102 when applying wake-up signals to DRX groups.

[0039] UE 102 can receive, for example, a WUS signal (510) from WANN 118. The WUS signal can be a downlink control indication (DCI). The index of the applicable DRX group that can be applied to the WUS can be indicated in the DCI. For example, the applicable DRX group of UE 102 can be indicated by a code point in the DCI. One code point can represent one DRX group. A code point value of "0" can indicate that the drx-ondurationTimer for that DRX group will not be activated for the corresponding DRX period, while a code point value of "1" can indicate that the drx-ondurationTimer for that DRX group will be activated for the corresponding DRX period.

[0040] Additionally or alternatively, the WUS signal may be a MAC CE that indicates the applicable DRX group. For example, the MAC CE may include a DRX group identifier, an indication of the drx-ondurationTimer status for each DRX group, and an indication of the number of time periods for the DRX group.

[0041] Alternatively or additionally, the WUS signal may apply only to the primary DRX group within a DRX group. A DRX group can be defined as a primary DRX group if it is used by a primary cell such as SpCe 111. Alternatively or additionally, UE 102 may determine the primary DRX group based on, for example, an indication in RRC signaling sent from WANN 118.

[0042] Then, UE 102 can determine the state of the DRX on-duration timer for the applicable DRX group (e.g., drx-ondurationTimer state) based on the WUS signal (520). In one implementation, if the WUS signal contains an identifier of the DRX group to which the WUS signal discussed above can be applied, UE 102 can determine the applicable DRX group based on the WUS signal. In this case, i.e., if the WUS signal is not received due to a bandwidth portion (BWP) switch, a measurement gap exists, or the WUS timing is within the UE active state, UE 102 can start the drx-ondurationTimer for all applicable DRX groups after the drx-slot offset for the corresponding period. If no WUS signal is received from the lower layer and ps-wakeup is configured for one or more DRX groups, UE 102 can start the on-duration timer for the applicable DRX group configured with ps-wakeup after the drx-slot offset for the corresponding period.

[0043] In another implementation, UE 102 can determine that the WUS signal is only applicable to DRX groups used by cells in which the WUS signal is received. In one implementation, a primary cell can be configured for each DRX group, and the WUS signal can be transmitted on the primary cell of each DRX group. In another implementation, the WUS signal can be transmitted on any cell in each DRX group. In this implementation, if the WUS signal is not received due to BWP handover, a measurement gap in the DRX group, or the WUS timing being within the UE's active state in the DRX group, UE 102 can start the drx-ondurationTimer for that DRX group after the drx-slotoffset for the corresponding period. If the WUS signal from the lower layer is not received in the DRX group and ps-wakeup is configured for the DRX group, UE 102 can start the onduration timer for the DRX group configured with ps-wakeup after the drx-slotoffset for the corresponding period.

[0044] Regarding ps-wakeup, it can be configured on a DRX group basis, and ps-wakeup is only available to the DRX group in which it is configured. Alternatively, ps-wakeup can be configured on the primary DRX group, and ps-wakeup is available to all DRX groups.

[0045] Here, the Channel State Information (CSI) reporting for DRX groups will be described. In one implementation, UE 102 determines whether it is active for the DRX group. If UE 102 is not active, it can determine the reason for its inactivity. If the reason is that a received WUS signal indicates that the drx-ondrationTimer is not started, UE 102 can determine whether the information element ps-TransmitOtherPeriodicCSI is configured for the DRX group. If ps-TransmitOtherPeriodicCSI is configured for the DRX group, UE 102 can report the CSI measurement results, rather than the Reference Signal Received Power (RSRP) CSI, via the Physical Uplink Control Channel (PUCCH). UE 102 can further determine whether the information element ps-TransmitPeriodicL1-RSRP is configured for the DRX group. If ps-TransmitPeriodicL1-RSRP is configured for the DRX group, UE 102 can report the RSRP CSI measurement results via the PUCCH.

[0046] The WUS signal may include parameters for configuring ps-TransmitOtherPeriodicCSI and ps-TransmitPeriodicL1-RSRP on different DRX configurations for UE 102. In one implementation, the WUS signal parameters can be configured individually for different DRX configurations. In another implementation, the WUS signal parameters in the primary DRX configuration should apply to all DRX groups.

[0047] Furthermore, if one DRX group of UE 102 is activated while another DRX group of UE 102 is deactivated, UE 102 may be configured to measure CSI in one DRX group while simultaneously reporting CSI in the other DRX group. In this case, UE 102 can use the state of the DRX group in which CSI measurement is performed as the state of UE 102. Alternatively, UE 102 can use the state of the DRX group in which CSI reporting is performed as the state of UE 102. Alternatively, UE 102 can use the state of the primary DRX group as the state of UE 102.
