[0125] The network node or network device mentioned in the embodiments of the present application can be a device that communicates with a terminal device. The network node or network device can provide communication coverage for a specific geographic area and can communicate with terminal devices (for example, UEs) located in the coverage area. Optionally, the network node or network device can be a base station (Base Transceiver Station, BTS) in a GSM system or a CDMA system, a base station (NodeB, NIB) in a WCDMA system, an evolved base station (eNB or eNodeB) in an LTE system, or a radio controller in a cloud radio access network (CRAN), or the network device or network device can be a relay station, an access point, a different antenna panel (Antenna panel) of the same base station, a transmitting-receiving point (Transmitting-Receiving point, TRP), a vehicle-mounted device, a wearable device, a network-side device in a future 5G network, or a network node or device in a future evolved public land mobile network (Public Land Mobile Network, PLMN), and the like.

[0126] The terminal device mentioned in the embodiments of the present application can be mobile or fixed. Alternatively, the terminal device can refer to an access terminal, a user equipment (UE), a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user apparatus. The access terminal can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved PLMN, etc.

[0127] Alternatively, in the embodiments of the present application, multiple network nodes can jointly serve the terminal device.

[0128] Alternatively, the multiple network nodes can perform downlink transmission to the terminal device through different beams. For example, network node 1 and network node 2 can perform downlink transmission to the terminal device through different beams.

[0129] Alternatively, in the embodiments of the present application, as shown in Figure 1 , the multiple network nodes can exchange information.

[0130] Alternatively, in the embodiments of the present application, different network nodes can be located in different cells, for example, as shown in Figure 1 ; or different network nodes can be transmission nodes in the same base station (gNB), for example, as shown in Figure 2 .

[0131] Alternatively, in the embodiments of the present application, the multiple network nodes can respectively send multiple PDCCHs or PDSCHs to the terminal device.

[0132] In this case, the terminal device can only receive one control channel, which indicates the configuration or scheduling information of the multiple network nodes (at this time, the control channel sent by each network node can carry the configuration or scheduling information of the terminal device configured or scheduled by the multiple network nodes).

[0133] Alternatively, the terminal device respectively receives the control channel sent from each network node, and each control channel can only carry the configuration or scheduling information of the terminal device configured or scheduled by the respective sender.

[0134] Optionally, the terminal device receives a plurality of network nodes simultaneously sending a Physical Downlink Control Channel (PDCCH) or a Physical Downlink Shared Channel (PDSCH) to the first terminal device.

[0135] Optionally, the first network node and the second network node simultaneously send a PDCCH or a PDSCH to the first terminal device through at least partially overlapping carriers in the frequency domain.

[0136] Optionally, the first network node and the second network node perform downlink transmission to the first terminal device through different transmission beams and / or different antenna panels.

[0137] Optionally, in the embodiments of the present application, the terminal device can perform uplink transmission to a plurality of network nodes respectively.

[0138] For example, in the case where the terminal device receives a PDCCH or a PDSCH sent by a plurality of network nodes, the terminal device can send a message to a plurality of network nodes respectively.

[0139] That is, in the case where there are a plurality of downlinks, there can be a plurality of corresponding uplinks.

[0140] Among them, the information of the uplink transmission at least contains one of the following signals:

[0141] Downlink transmission corresponding Acknowledge (ACK) / Non-Acknowledge (NACK), and corresponding Channel State Information (CSI) and other information, uplink data and Sounding Reference Signal (SRS).

[0142] There are two ways for the transmission of a plurality of uplinks:

[0143] Method 1: The signals of a plurality of uplinks are not sent at the same time.

[0144] Method 2: The signals of a plurality of uplinks can be sent at the same time.

[0145] For the first mode, the network side coordinates and makes multiple uplink transmissions in a time division multiplexing (TDM) manner through signaling; for the second mode, multiple uplink signals are transmitted simultaneously, and a power limited power control method needs to be considered

[0146] Therefore, in the case of multiple uplinks, how to achieve reasonable configuration or scheduling of the network side is an urgent problem to be solved.

[0147] Figure 3 is a schematic flowchart of a wireless communication method 100 according to an embodiment of the present application. The method 100 includes at least part of the following contents.

[0148] In 110, the terminal device calculates at least one power headroom report (PHR) to be reported to the first network node according to a transmission channel of a first uplink between the terminal device and the first network node, wherein the first network node and the second network node serve the terminal device.

[0149] In 120, the terminal device reports the calculated at least one PHR to the first network node through the first uplink.

[0150] In 130, the first network node receives at least one power headroom report PHR sent by the terminal device, and the at least one PHR is calculated based on a transmission channel of a first uplink between the terminal device and the first network node, wherein the first network node and the second network node serve the terminal device.

[0151] In 140, the first network node configures or schedules the terminal device based on the at least one PHR.

[0152] Optionally, a first PHR is calculated using the transmission channel of the first uplink without considering a transmission channel of a second uplink between the terminal device and the second network node; and wherein the at least one PHR reported to the first network node includes the first PHR.

[0153] Optionally, a second PHR is calculated using the transmission channel of the first uplink in combination with a transmission channel of a second uplink between the terminal device and the second network node; and wherein the at least one PHR reported to the first network node includes the second PHR.

[0154] Optionally, the third PHR is calculated by using the transmission channel of the second uplink without considering the transmission channel of the first uplink between the terminal device and the first network node, and the third PHR can be reported to the first network node.

[0155] Therefore, in the embodiments of the present application, the first network node can receive the first PHR, or the second PHR, or the third PHR, or the first and second PHRs, or the first and third PHRs, or the second and third PHRs, or the first, second and third PHRs.

[0156] Optionally, the terminal device can report at least one of the first PHR, the second PHR and the third PHR calculated above to the second network node.

[0157] Specifically, the terminal device can report at least one of the first PHR, the second PHR and the third PHR to the second network node through the second uplink.

[0158] Optionally, the first network node and the second network node belong to the same cell; or,

[0159] The first network node and the second network node belong to different cells.

[0160] Optionally, in the embodiments of the present application, the terminal device determines the PHR to be reported to the first network node according to network configuration or preset information.

[0161] Optionally, in the embodiments of the present application, the PHR calculated according to the transmission channel of the link can be calculated by considering the control channel of the link without considering the data channel; or calculated by considering the data channel of the link without considering the control channel; or calculated by considering both the data channel and the control channel of the link.

[0162] Optionally, the network node can schedule the terminal device in combination with the channel considered by the terminal device when calculating the PHR.

[0163] For example, when calculating the PHR, the terminal device only considers the data channel of a certain link without considering the control channel, and when scheduling the terminal device, the network node also considers whether to schedule the data channel without considering the control channel. However, the present application is not limited thereto.

[0164] Optionally, the PHR to be reported to the first network node is associated with the communication quality index of the channel between the first network node and the second network node.

[0165] Specifically, the embodiments of the present application can be applied to the following four scenarios.

[0166] Scenario 1. Multiple network nodes belong to the same cell, and the connection (backhaul) between the network nodes is ideal, i.e., information interaction can be quickly performed, and dynamic information interaction can be performed.

[0167] Scenario 2. Multiple network nodes belong to the same cell, and the connection (backhaul) between the network nodes is non-ideal, i.e., information interaction between the network nodes cannot be quickly performed, and only relatively slow data interaction can be performed.

[0176] In order to facilitate understanding, the present application will be described below in combination with several embodiments.

[0177] Embodiment 1

[0178] The UE calculates PHR1 according to the transmission channel (control channel and / or data channel) on uplink 1; and calculates PHR2 according to the transmission channel (control channel and / or data channel) on uplink 2.

[0179] The UE reports PHR1 to network node 1 through uplink 1; and the UE reports PHR2 to network node 2 through uplink 2.

[0180] Embodiment 1 can save the reporting, and the implementation in the embodiment 1 is more suitable for the UE to perform the uplink transmission in a TDM manner on multiple links.

[0181] Embodiment 2

[0182] The UE calculates PHR1 according to the transmission channel (control channel and / or data channel) on uplink 1; and the UE calculates PHR2 according to the transmission channel (control channel and / or data channel) on uplink 2.

[0183] The reporting manner of PHR has the following ways:

[0184] The UE reports PHR1 and PHR2 to network node 1 through uplink 1; and / or the UE reports PHR1 and PHR2 to network node 2 through uplink 2; or,

[0185] The UE reports PHR1 and PHR2 to network node 1 through uplink 1; and the UE reports PHR2 to network node 2 through uplink 2; or

[0186] The UE reports PHR1 to network node 1 through uplink 1; and the UE reports PHR1 and PHR2 to network node 2 through uplink 2

[0187] Embodiment 3

[0188] The UE calculates PHR1 according to the transmission channel (control channel and / or data channel) on uplink 1; the UE calculates PHR2 according to the transmission channel (control channel and / or data channel) on uplink 2; and the UE calculates PHR3 according to the transmission channel (control channel and / or data channel) on uplink 1 and the transmission channel (control channel and / or data channel) on uplink 2.

[0189] The reporting manner of PHR has the following possible options:

[0190] The UE reports PHR1, PHR2 and PHR3 to network node 1 through uplink 1; and / or the UE reports PHR1, PHR2 and PHR3 to network node 2 through uplink 2; or,

[0192] The UE reports PHR1 and PHR3 to the network node 1 through uplink 1; the UE reports PHR2 to the network node 2 through uplink 2; or,

[0193] The UE reports PHR1 to the network node 1 through uplink 1; the UE reports PHR2 and PHR3 to the network node 2 through uplink 2.

[0194] For Embodiment 2 and Embodiment 3, the network (non-ideal backhaul scenario between TRPs / beams / cells) can determine whether the UE can simultaneously transmit signals of two uplinks according to multiple PHRs reported by the UE; if so, the network can configure or schedule the UE to use simultaneous uplink transmission on multiple links, thereby improving resource utilization efficiency; if the UE power cannot support simultaneous transmission of signals of two uplinks, the network can configure or schedule the UE to transmit signals of one uplink.

[0195] Optionally, in the embodiments of the present application, after receiving the PHR reported by the terminal device, the first network node can schedule the terminal device according to the PHR.

[0196] For example, if the second PHR reported by the terminal device to the first network node indicates that the terminal device can simultaneously perform uplink transmission using the first link and the second link, the first network node can directly schedule the terminal device without consulting the second network node.

[0197] For example, if the second PHR reported by the terminal device to the first network node indicates that the terminal device cannot simultaneously perform uplink transmission using the first link and the second link, the first network node can consult the second network node to schedule the terminal device.

[0198] For example, if the first PHR and the third PHR reported by the terminal device to the first network node respectively represent that there is a large amount of power remaining, the first network node and the second network node can consult the UE to simultaneously perform uplink transmission on multiple links.

[0199] It is also understood that, although the first uplink and the second uplink are described in the embodiments of the present application, it does not mean that there are only two uplinks for simultaneous transmission. For example, the first uplink can include multiple uplinks, or the second uplink can include multiple uplinks, or there can be other third uplinks simultaneously.

[0200] Optionally, the first network node communicates with the terminal device through a first carrier, and the second network node communicates with the terminal device through a second carrier. At this time, the terminal device communicates with the network device through multiple carriers, and this scenario can be a dual connectivity scenario. For example, a LTE-NR dual connectivity scenario.

[0201] Optionally, the first network node and the second network node are physically independent nodes; or, the first network node and the second network node are implemented through the same physical node.

[0202] Optionally, the first carrier is a carrier in a first carrier group, and the second carrier is a carrier in a second carrier group which is not the first carrier group. For example, the first carrier group is a primary carrier group, and the second carrier group is a secondary carrier group. Alternatively, the first carrier group is a secondary carrier group, and the second carrier group is a primary carrier group.

[0203] Optionally, the first carrier is a carrier of a communication system with a first communication standard, and the second carrier is a carrier of a communication system with a second communication standard which is not the first communication standard.

Of course, the first communication standard and the second communication standard can also be other different communication standards.

[0205] Optionally, the first carrier and the second carrier completely or partially overlap in the frequency domain.

[0206] Therefore, in the embodiments of the present application, the terminal device reports at least one PHR corresponding to at least one link to at least one network node in the case of multiple uplinks, so that the network node can configure or schedule the terminal device in combination with the PHR corresponding to the link, thereby achieving reasonable configuration or scheduling of the terminal device and improving system performance.

[0219] For example, the terminal device reports the second PHR to the network device, and if the first PHR indicates that the power of the terminal device is insufficient to simultaneously transmit the first service and the second service, the network device can configure or schedule the terminal device to transmit the first service and the second service in a different manner.

[0220] Optionally, the first service is an Ultra-Reliable Low latency Communications (URLLC) service, and the second service is an Enhance Mobile Broadband (eMBB) service.

[0221] It is also understood that, in the embodiments of the present application, although described by the first service and the second service, it does not mean that there are only two services transmitted at the same time.
