METHOD OF POWER MEASUREMENT REPORTING AND RELEVANT DEVICES
[0001] BACKGROUND OF DISCLOSURE
[0002] 1. Field of the Disclosure
[0003] The present application relates to the field of communication systems, and more particularly, to a method of power measurement reporting and relevant devices.2. Description of the Related Art
[0004] In cellular wireless communication systems developed by the Third Generation Partnership Project (3GPP) , user equipment (UE) is connected by a wireless link to a radio access network (RAN) . The RAN includes a set of base stations (BSs) which provide wireless links to UEs located in cells covered by the base station and an interface to a core network (CN) which provides overall network control. The RAN and CN each conduct respective functions in relation to the overall network. The so-called 4G Long Term Evolution (LTE) system, namely, an Evolved Universal Mobile Telecommunication System Territorial Radio Access Network (E-UTRAN) has been developed for a mobile access network where one or more macro-cells are supported by a base station known as an eNodeB or eNB (evolved NodeB) . Evolved from LTE, the so-called 5G or new radio (NR) systems where one or more cells are supported by a base station known as a gNB. Envisioned to succeed the current 5G networks, the 6G cellular system is the forthcoming generation of wireless communication technology.
[0005] NR / 5G system supports FR2 (frequency range 2) operation. The NR system in FR2 is generally a multi-beam-based system, where the gNB has multiple downlink Tx beams that are available for downlink transmission and the UE could have multiple Rx beams available for downlink transmission reception. For the uplink transmission, the UE might have multiple Tx beams available for transmission and the gNB has multiple uplink Rx beams that are available for uplink reception. To support proper communication, the gNB and the UE find the best pair of gNB Tx beam and UE Rx beam. The NR introduces beam measurement and reporting in CSI framework to support the selection of best Tx beam and Rx beam. The NR also supports the functions of beam indication for downlink reception and uplink transmission. The gNB can indicate the information of Tx beam of PDCCH and PDSCH to the UE to assist the downlink reception at the UE side. The gNB can also indicate the information of Tx beam of PUSCH, PUCCH and SRS to the UE to indicate the UE about how to transmit the PUSCH, PUCCH and SRS.
[0006] The NR / 5G systems implement the function of beam indication through the signaling of TCI states. The UE can be first provided with a list of joint TCI states, or a list of DL TCI states and a list of UL TCI states. Each joint TCI state can provide the configuration information of QCL typeD for downlink reception (where the QCL typeD provides the spatial Rx parameter for downlink reception) and reference information of UL Tx spatial filter for uplink transmission. Each joint TCI state can be associated with a set of uplink power control parameters, including P0, alpha, index of closed loop power control and the pathloss RS. Each DL TCI state can provide the configuration information of QCL typeD for downlink reception. Each UL TCI state can provide the reference information of UL Tx spatial filter for uplink transmission and each UL TCI state can also be associated with a set of uplink power control parameters, including P0, alpha, index of closed loop and pathloss RS.
[0007] The gNB can indicate on joint TCI state or a pair of DL TCI states and UL TCI states to the UE through a DCI signaling. When the UE receives the DCI signaling for TCI state indication, the UE feedbacks one ACK to the gNB. Then the indicated TCI state (s) should be applied starting from the first slot that is at least beamAppTime symbols after the last symbols of the PUCCH or PUSCH that carries the ACK. From the information of QCL TypeD in the indicated TCI state, the UE would derive the Rx beam for receiving the PDCCH and PDSCH. From the information of UL Tx spatial filter in the indicated TCI state, the UE would derive the Tx beam for transmitting the PUSCH, PUCCH and / or SRS. From the indicated TCI state, the UE would derive the uplink power control parameters and pathloss RS and then calculate the uplink transmit power for the PUSCH, PUCCH and / or SRS transmission.
[0008] To support the system to choose proper TCI states, the NR specification also supports the functions of beam measurement and reporting. The system can configure the UE to measure a set of reference signals, such as CSI-RS resources and / or SS / PBCH blocks and the UE can be requested to report the measurement results to the system. The reported measurement result can include the indicator of selected CSI-RS resource or SS / PBCH and the corresponding L1-RSRP or L1-SINR measurement.
[0009] One drawback of the existing method of beam measurement and reporting is that the gNB controls the beam measurement and reporting but the gNB might not know the beam quality very well. That might cause two consequences: firstly, if the system configures very frequent beam reporting, the reporting costs large overhead, and thus, the uplink transmission efficiency is impaired. On the other hand, if the system configures less frequent beam reporting, the reporting overhead is reduced but the system cannot obtain the channel information in time.SUMMARY

The transceiver 13 or 23 is operatively coupled with the processor 11 or 21, and the transceiver 13 or 23 transmits and / or receives a radio signal. When the wireless communication system 30 complies with the New Radio (NR) standard of the 3rd Generation Partnership Project (3GPP) , the next generation core network is a backend serving network system and may include an Access and Mobility Management Function (AMF) , User Plane Function (UPF) , and a Session Management Function (SMF) . In one aspect, the terminal device 10 can include almost any consumer electronic device or appliance that can connect to a radio access network and a core network for the releases of 3GPP and further, such as, but not limited to NR networks.
[0034] The processor 11 or 21 may include application-specific integrated circuit (ASIC) , other chipset, logic circuit and / or data processing device. The memory 12 or 22 may include read-only memory (ROM) , random access memory (RAM) , flash memory, memory card, storage medium and / or other storage device.

This facilitates determining the corresponding TCI state for one event-trigger power measurement reporting.
[0037] FIG. 2 illustrates a method of power measurement reporting 100 by a terminal device according to an embodiment of the present application. In some embodiments, the method 100 includes the following. In Block 102, the terminal device (e.g., a user equipment (UE) ) reports to a network device (e.g., a base station or gNB) one power measurement reporting (e.g., L1-RSRP reporting) . The power measurement reporting is triggered by an event (and is initiated by the terminal device) and contains power measurement (e.g., L1-RSRP measurement) of a certain number (i.e., K entities) of physical reference signal (RS) resources (i.e., CSI-RS resources or SSBs) in a configured list of physical RS resources and also power management (e.g., L1-RSRP measurement) of a measurement RS corresponding to an indicated transmission configuration indicator (TCI) state. More particularly, the reported power measurement of the measurement RS corresponding to the indicated TCI state corresponds to a TCI state that the terminal device applies or applied in a temporal interval that is on or before the power measurement reporting is executed. The indicated TCI state may be an indicated joint TCI state or downlink (DL) TCI state. The reported power measurement of the measurement RS corresponding to the indicated TCI state may include a differential power measurement value with a reference to a largest power measurement value in the same reporting instance. The terminal device may further report to the network device one indicator of the indicated TCI state that the reported power measurement of the measurement RS corresponds to. The indicator of the indicated TCI state may be carried by a value of codepoint that the indicated TCI state is mapped to through a media access control (MAC) control element (CE) message.
[0038] In some embodiments, the power measurement reporting is executed at slot n, and the reported power measurement of the measurement RS corresponding to the indicated TCI state corresponds to the TCI state that the terminal device applies in the slot n, where n is a non-negative integer. In some other embodiments, the power measurement reporting is executed at slot n, and the reported power measurement of the measurement RS corresponding to the indicated TCI state corresponds to the TCI state that the terminal device applied in slot n-N, where n and N are non-negative integers.
[0039] In some embodiments, the power measurement reporting is executed at slot n, and the reported power measurement of the measurement RS corresponding to the indicated TCI state corresponds to the TCI state that the terminal device applied in a last slot that is at least N1 symbols before a first symbol of a physical uplink channel carrying the power measurement reporting at slot n, where n and N1 are non-negative integers. In some other embodiments, the power measurement reporting is executed at slot n, and the reported power measurement of the measurement RS corresponding to the indicated TCI state corresponds to the TCI state that the terminal device applied in a last slot that is at least a time duration before a first symbol of a physical uplink channel carrying the power measurement reporting at slot n, where n is a non-negative integer.
[0040] The proposed power measurement reporting method 100 can provide a solution that the system and the terminal device are able to determine the corresponding TCI state for one event-trigger power measurement reporting (e.g., L1-RSRP reporting) .
[0041] FIG. 3 illustrates a method of power measurement reporting 200 by a network device according to an embodiment of the present application. In some embodiments, the method 200 includes the following. In Block 202, the network device (e.g., base station or gNB) receives from a terminal device (e.g., a user equipment (UE) ) one power measurement reporting (e.g., L1-RSRP reporting) . The power measurement reporting is triggered by an event (and is initiated by the terminal device) and contains power measurement (e.g., L1-RSRP measurement) of a certain number (i.e., K entities) of physical reference signal (RS) resources (i.e., CSI-RS resources or SSBs) in a configured list of physical RS resources and also power management (e.g., L1-RSRP measurement) of a measurement RS corresponding to an indicated transmission configuration indicator (TCI) state. More particularly, the reported power measurement of the measurement RS corresponding to the indicated TCI state corresponds to a TCI state that the terminal device applies or applied in a temporal interval that is on or before the power measurement reporting is executed. This facilitates determining the corresponding TCI state for one event-trigger power measurement reporting. Other details of the method 200 may be referred to the method 100 described above and are not repeated herein.
[0042] Further details about the invention are provided below.
[0043] In one embodiment, a UE can be provided with a list of joint TCI states or a list of DL TCI states and a list of UL TCI states. The system can activate one or more joint TCI state through a MAC CE message and map one joint TCI state to one code point of the DCI TCI field. The system can activate one or more pair of DL TCI states and / or UL TCI states through a MAC CE message and map one DL TCI state and / or UL TCI state to one code point of the DCI TCI field. The system then can use DCI format 1_1 / 1_2 to indicate one joint TCI state to the UE. The system can use DCI format 1_1 / 1_2 to indicate a DL TCI state and / or UL TCI state to the UE. When the UE transmits a PUCCH with HARQ-ACK information or a PUSCH with HARQ-ACK information corresponding to the DCI carrying the TCI state indication or corresponding to the PDSCH scheduled by the DCI carrying the TCI state indication, the UE shall apply the indicated joint TCI state (or the indicated DL TCI state and / or UL TCI state) from the first slot that is at least beamAppTime symbols after the last symbol of the PUCCH or the PUSCH with the HARQ-ACK information.
[0044] The UE can be configured with L1-RSRP measurement reporting with an event trigger. For that, the UE is provided with a first list of CSI-RS resources and / or SS / PBCH blocks (SSBs) . The UE can be also provided with a first L1-RSRP threshold value and a first length of time duration. The UE can be requested to derive a first measurement RS (which can be a CSI-RS resource or a SS / PBCH block) from the indicated joint TCI state or DL TCI state. The UE can be requested to compare the L1-RSRP of the RS configured in the first list with the L1-RSRP of the first measurement RS. When the configured condition is met, the UE can be requested to report the L1-RSRP measurements of K CSI-RS resources or SS / PBCH blocks configured in the first list. The UE can also be requested to report the L1-RSRP measurement of the first measurement RS corresponding to the indicated joint TCI state or DL TCI state. The UE can report one L1-RSRP measurement report for the trigger event at slot n. Here we need to clarify which of the TCI state the L1-RSRP of the first measurement RS correspond to. The reason is that the system could use DCI format 1_1 / 1_2 to switch the TCI state from time to time. The indicated TCI state at the slot where the L1-RSRP reporting is sent could be different from the indicated TCI state during the time period when the triggered event is detected.
[0045] In a first method, the UE can report one L1-RSRP reporting at slot n, which contains the L1-RSRP measurement of K CSI-RS resources or SSBs configured in the first list, and also the L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state. Here the L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state could be one differential L1-RSRP value with a reference to the largest L1-RSRP reported in the same reporting instance. In one example, the reported L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state could correspond to the indicated joint TCI state or DL TCI state that the UE applies on the system in the slot n.
[0046] In a second method, the UE can report one L1-RSRP reporting at slot n, which contains the L1-RSRP measurement of K CSI-RS resources or SSBs configured in the first list, and also the L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state. Here the L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state could be one differential L1-RSRP value with a reference to the largest L1-RSRP reported in the same reporting instance. In one example, the reported L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state could correspond to the indicated joint TCI state or DL TCI state that the UE applied on the system in the slot n-N, where N can be a slot number configured by the system.
[0047] In a third method, the UE can report one L1-RSRP reporting at slot n, which contains the L1-RSRP measurement of K CSI-RS resources or SSBs configured in the first list, and also the L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state. Here the L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state could be one differential L1-RSRP value with a reference to the largest L1-RSRP reported in the same reporting instance. In one example, the reported L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state could correspond to the indicated joint TCI state or DL TCI state that the UE applied on the system in the last slot that is at least N1 symbols before the first symbol of PUCCH or PUSCH carrying the L1-RSRP reporting at slot n, where N1 can be symbol number configured by the system. In another example, the reported L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state could correspond to the indicated joint TCI state or DL TCI state that the UE applied on the system in the last slot that is at least a time duration before the first symbol of PUCCH or PUSCH carrying the L1-RSRP reporting at slot n, where the length of the time duration can be configured by the system.
[0048] In a method, the UE can report one L1-RSRP reporting at slot n, which contains the L1-RSRP measurement of K CSI-RS resources or SSBs configured in the first list, and also the L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state. The UE can also be requested to report one indicator of the indicated TCI state that the reported L1-RSRP measurement of the measurement RS corresponds to. Here the L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state could be one differential L1-RSRP value with a reference to the largest L1-RSRP reported in the same reporting instance. The indicator of the indicated TCI state reported by the UE can be the value of the codepoint that the indicated TCI state (joint TCI state or DL TCI state) is mapped to through the MAC CE message.
[0049] ● In one example, the reported L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state could correspond to the indicated joint TCI state or DL TCI state that the UE applies on the system in the slot n.
[0050] ● In one example, the reported L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state could correspond to the indicated joint TCI state or DL TCI state that the UE applied on the system in the slot n-N, where N can be a slot number configured by the system.
[0051] ● In one example, the reported L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state could correspond to the indicated joint TCI state or DL TCI state that the UE applied on the system in the last slot that is at least N1 symbols before the first symbol of PUCCH or PUSCH carrying the L1-RSRP reporting at slot n, where N1 can be symbol number configured by the system. In another example, the reported L1-RSRP measurement of the measurement RS corresponding to the indicated TCI state could correspond to the indicated joint TCI state or DL TCI state that the UE applied on the system in the last slot that is at least a time duration before the first symbol of PUCCH or PUSCH carrying the L1-RSRP reporting at slot n, where the length of the time duration can be configured by the system.
