As a further example, as used in this application, the term circuitry also encompasses implementations of only hardware circuits or processors (or one or more processors) or portions of hardware circuits or processors and their (or their) attendant software and / or firmware. For example and where applicable to a particular claim element, the term "circuitry" also encompasses a baseband integrated circuit or a processor integrated circuit for a mobile device, or a similar integrated circuit in a server, a cellular network device, or other computing or network device.

[0043] As used herein, the term "communication network" refers to a network that complies with any suitable communication standard, such as Long Term Evolution (LTE), LTE-Advanced (LTE-A), Wideband Code Division Multiple Access (WCDMA), High Speed Packet Access (HSPA), NarrowBand Internet of Things (NB-IoT), etc. In addition, the communication between the terminal device and the network device in the communication network can be performed according to any suitable generation of communication protocol, including but not limited to the third generation (3G), fourth generation (4G), 4.5G, fifth generation (5G) communication protocol, and / or more generations of communication protocols. Embodiments of the present disclosure can be applied to various communication systems. Given the rapid development of communication, there will of course be future types of communication technologies and systems that utilize it to implement the present disclosure. It should not be regarded as limiting the scope of the present disclosure to the above systems.

[0044] As used herein, the term "network device" refers to a node in a communication network through which a terminal device accesses the network and receives services from the network. Depending on the terminology and technology applied, the network device may refer to a base station (BS) or an access point (AP), such as Node B (NodeB or NB), evolved Node B (eNodeB or eNB), NR NB (also known as gNB), Remote Radio Unit (RRU), Radio Head (RH), Remote Radio Head (RRH), relay, low-power node (such as femto, pico), etc.

[0045] The term "terminal device" refers to any terminal device capable of wireless communication. By way of example and not limitation, the terminal device may also be referred to as a communication device, user equipment (UE), user station (SS), portable user station, mobile station (MS), or access terminal (AT). The terminal device may include but is not limited to mobile phones, cellular phones, smart phones, Voice over Internet Protocol (VoIP) phones, wireless local loop phones, tablets, wearable terminal devices, personal digital assistants (PDA), portable computers, desktop computers, image capture terminal devices such as digital cameras, game terminal devices, music storage and playback applications, in-vehicle wireless terminal devices, wireless endpoints, mobile stations, laptop embedded devices (LEE), laptop mounted devices (LME), USB dongles, smart devices, wireless client devices (CPE), Internet of Things (IoT) devices, watches or other wearable devices, head-mounted displays (HMD), vehicles, drones, medical devices and applications (e.g., remote surgery), industrial devices and applications (e.g., robots and / or other wireless devices operating in an industrial and / or automated processing chain environment), consumer electronic devices, devices operating on commercial and / or industrial wireless networks, etc. In the following description, the terms "terminal device", "communication device", "terminal", "user equipment", and "UE" may be used interchangeably.

[0046] Simultaneous UL transmissions in the same cell will be specified in Release 18 New Radio (NR). On the other hand, based on the existing specifications, in scenarios such as inter-band carrier aggregation (CA) for example, the terminal device is allowed to perform simultaneous UL transmissions in different cells.

[0047] The output power level of the terminal device is partly defined by the UE power class, which defines the nominal maximum output power for QPSK modulation. This UE power class can be different in different operating frequency bands, but for all bands, the main UE power class is currently set to 23 dBm.

[0048] For example, in TS 38.101, the UE maximum output power P cmax,f,c , a lower reduction term or factor is defined. In the CA scenario, the terminal device is allowed to use a transmission power exceeding 23 dBm in some cases (such as those conditions related to the duty cycle). Whether it can exceed 23 dBm is evaluated and dynamically determined by the terminal device. For the determination of P cmax,f,c , a 3 dB reduction also needs to be considered, which depends on the rules and conditions captured above.

[0049] The inventors have noted that for UL transmissions in the same cell or different cells, especially simultaneous UL transmissions, it is necessary for the network to have good and dynamic control over the interference level and more generally the power level, especially when the terminal device will transmit using high power (e.g., a power of approximately 23 dBm or higher). From another perspective, depending on the service priority, or service type / requirements (e.g., related to data rate, latency, reliability), the terminal device is able to operate using a transmission power lower than a certain level that would be allocated by the network device.

[0050] The inventors have also noted that in the existing specifications and operations, the network cannot dynamically consider and control the UL transmission power, and this will clearly have a negative impact from at least the perspectives of power saving and interference management.

[0051] Therefore, according to an embodiment of the present disclosure, a solution for uplink transmission power control is provided. In this solution, the terminal device obtains a power indication from the network device, where the power indication indicates whether the terminal device is allowed to use a transmission power greater than a threshold. Based on this power indication, the terminal device determines the transmission power for one or more uplink transmissions. Thus, the transmission power for uplink transmissions can be well and dynamically controlled, thereby improving communication efficiency and communication performance.

[0052] In some other examples, the terminal device may also provide the network device with assistance information on whether the terminal device needs to operate using a transmission power greater than a certain level, which can enable the network device to have good and dynamic control over, for example, the interference level.

[0053] As used herein, the term "beam" may refer to a communication resource. Different beams may be considered different resources. A beam may also be represented as a spatial filter. Communication devices (including terminal devices and network devices) may communicate with another communication device via one or more beams. A beam may include one or more antenna ports and be configured for data channels, control channels, etc. A beam may be configured with a set of resources, or a set of resources for measurement, and a beam may be represented by, for example, a reference signal, and / or related resources for the reference signal. A beam may also be represented by a reference cell identifier, or a resource identifier.

[0054] As used herein, the term "TCI state" may refer to a transmission configuration indicator state, which may be used by a network station to indicate a beam to a terminal device. The TCI state may define a quasi co-location (QCL) source and QCL type for a target reference signal, and thus indicate a transmission configuration including the QCL relationship between DL RSs included in an RS set. In particular, the TCI state may include, for example, a TCI state ID, QCL information, etc. The QCL information may include, for example, QLC type A and QLC type B (optional). The QCL information includes, for example, a serving cell index and a partial bandwidth (BWP) ID, a downlink reference signal synchronization signal (SS) / physical broadcast channel (PBCH) block (SSB), or a channel state information reference signal (CSI-RS), and may also include information on an uplink reference signal, such as a sounding reference signal (SRS). According to the information in the TCI state, the terminal device may obtain beam-related information.

[0055] As used herein, the term "CA" refers to carrier aggregation that allows a mobile operator or device to combine two or more carriers. It results in an increase in network capacity and data rate by utilizing fragmented spectrum allocation. In carrier aggregation, multiple frequency bands are assigned to a device. There are six specific frequencies as follows: 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, and 20 MHz. These component carriers may be combined to transmit an aggregated bandwidth of up to 100 MHz.

[0056] It should be noted that in the present disclosure, a (UL) beam may also refer to spatial relation information, a (separate) UL transmission configuration indicator (TCI) state, a joint TCI state, or a common TCI state, a spatial filter, power control information (or a set of power control parameters), a panel or a panel identity (ID), a quasi-co-location information type-D (or any other type, such as type A, type B, or type C), etc. More generally, all these terms may be used interchangeably.

[0057] It should also be noted that a UE panel may be identified by an index of a corresponding set of UE capability values or by a panel ID. Alternatively or additionally, the panel may be identified or associated by at least one DL RS (or more generally an RS), or simply by a UL beam.

[0058] Examples of the present disclosure for beam alignment will be described below with reference to Figures 1 to 7 illustrate exemplary embodiments of the present disclosure for beam alignment.

[0059] Figure 1 An exemplary network environment 100 in which exemplary embodiments of the present disclosure may be implemented is shown. Environment 100 (which may be part of a communication network) includes a terminal device and a network device.

[0060] As Figure 1 shown, the communication network 100 may include a terminal device 110 (which may also be referred to hereinafter as a user equipment 110 or a UE 110). The communication network 100 may also include a network device 120. The network device 120 may manage the cell 101. The terminal device 110 and the network device 120 may communicate with each other within the coverage of the cell 101. The link from the terminal device 110 to the network device 120 is referred to as an uplink (UL), while the link from the network device 120 to the terminal device 110 is referred to as a downlink (DL).

[0061] It should be understood that the number of network devices and terminal devices is for illustrative purposes only and does not imply any limitation. The system 100 may include any suitable number of network devices and terminal devices suitable for implementing the embodiments of the present disclosure. Although not shown, it should be understood that one or more terminal devices may be located in the environment 100.

[0062] Communication in the network environment 100 can be implemented according to any suitable communication protocol, including but not limited to the third generation (3G), fourth generation (4G), fifth generation (5G) or beyond, wireless local area network communication protocols such as Institute of Electrical and Electronics Engineers (IEEE) 802.11, and / or any other protocol known currently or to be developed in the future. In addition, the communication can utilize any suitable wireless communication technology, including but not limited to: multiple-input multiple-output (MIMO), orthogonal frequency-division multiplexing (OFDM), time-division multiplexing (TDM), frequency-division multiplexing (FDM), code-division multiplexing (CDM), Bluetooth, ZigBee, and machine type communication (MTC), enhanced mobile broadband (eMBB), massive machine type communication (mMTC), ultra-reliable low-latency communication (URLLC), carrier aggregation (CA), dual connectivity (DC), and new radio unlicensed (NR-U) technology.

[0063] In some embodiments of the present disclosure, the network device 120 can determine whether the terminal device is allowed to use a transmission power greater than a threshold; and provide a power indication to the terminal device 110, where the power indication indicates whether the terminal device is allowed to use a transmission power greater than the threshold.

[0064] In some embodiments of the present disclosure, the terminal device 110 obtains a power indication from the network device 120, where the power indication indicates whether the terminal device is allowed to use a transmission power greater than a threshold. Based on the power indication, the terminal device 110 determines the transmission power for one or more uplink transmissions. Then, the network device 120 can perform uplink transmission power control.

[0065] Figure 2 An example flowchart of a method 200 implemented at the terminal device 110 according to some embodiments of the present disclosure is shown. For the purpose of discussion, method 200 will be described with reference to Figure 1 Method 200 will be described from the perspective of the terminal device 110. It should be understood that method 200 may also include additional blocks not shown, and / or omit some of the shown blocks, and the scope of the present disclosure is not limited thereto.

[0066] At block 210, the terminal device 110 obtains a power indication from the network device 120, where the power indication indicates whether the terminal device is allowed to use a transmission power greater than a threshold. In other words, the network device 120 indicates to the terminal device whether the terminal device is allowed to use a transmission power greater than the threshold. It should be understood that the "threshold" is not limited to one threshold, and it may include one or more thresholds.

[0067] The terminal device 110 may receive, from the network device 120, a power indication regarding whether the terminal device 110 may use a transmission power greater than one of at least one configured threshold. For example, the power indication may be received via: a media access control control element (MAC CE), or a downlink control indication (DCI). In an example, a new or existing field / bit in the DCI and / or in the MAC CE may be used to carry the power indication.

[0068] In some embodiments, the terminal device 110 may also receive, for example, before receiving the power indication, a power configuration from the network device. The power configuration provides information enabling the reception of the power indication at the terminal device 110. The power configuration may be carried by, for example, a radio resource control (RRC) message. For example, the terminal device 110 may be configured (e.g., via an RRC message) to receive such an indication within a DCI, a physical downlink control channel (PDCCH) (e.g., having a specific format), or some existing or new MAC CE.

[0069] In some embodiments, the terminal device 110 may obtain offset information for the transmission power. The offset information indicates the amount of power by which the transmission power is permitted to exceed the threshold. In an example, when the terminal device 110 is indicated that it may use a transmission power greater than the threshold, the network device 120 may additionally indicate the offset to the terminal device 110. The offset may indicate how much the terminal device 110 is permitted to exceed the threshold.

[0070] In some embodiments, the offset information may be included in the power indication. In some embodiments, the offset information may be configured via a separate message (such as RRC signaling). For example, a new or existing field / bit in the DCI and / or in the MAC CE may be used to carry such an offset indication. The indication of the offset may even be carried via RRC signaling. In some embodiments, the offset information may be defined by a communication specification.

[0071] In some embodiments, the terminal device 110 may also receive a threshold from the network device. In an example, the threshold may be configured by a gNB or may also be defined in a communication specification. For another example, the threshold may be included in the power indication or the power configuration. For example, different thresholds may be defined for different terminal device power levels. Figure 3 An example signaling procedure is shown and will be described in detail later with reference to Figure 3 which.

[0072] In some embodiments, additionally or alternatively, the terminal device 110 may determine whether the terminal device needs to use a transmission power greater than a threshold based on power usage-related conditions. The power usage-related conditions may include one or more of the following: service priority, uplink transmission scheme or mode, service type, service requirement, logical channel priority, physical channel priority, coverage, or channel quality.

[0073] Then, the terminal device 110 may send a power request to the network device 120, where the power request indicates that the terminal device 110 needs to use a transmission power greater than a threshold or another threshold. In some embodiments, the power request may also indicate that the terminal device 110 does not need to use a transmission power greater than the threshold. The threshold indicated in the power request may be equal to the threshold indicated in the power indication, and these two thresholds may also be different.

[0074] In an example, the terminal device 110 may report or request whether it needs or prefers to use a transmission power greater than a configured threshold. The decision on the report or request may be based on service priority, uplink transmission scheme or mode (e.g., simultaneous UL transmission and single-board UL transmission), service type, service requirements (regarding latency, data rate, reliability, etc.), or logical channel priority, physical channel priority. Alternatively, or additionally, this decision may be based on coverage (whether the terminal device is restricted in coverage) or channel quality, e.g., based on whether a certain measurement (such as reference signal received power (RSRP)) is lower than a configured threshold.

[0075] In some embodiments, the power request may be sent according to a waveform type, and the waveform type may be indicated in the power request. In some embodiments, the power request is sent as uplink control information (UCI) on a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).

[0076] In some embodiments, the power request may be sent when the waveform type changes. In some embodiments, the power request may be sent according to a digital technique. For example, if the transmission power is higher, the duty cycle of the waveform type may be smaller. Therefore, if the transmission power is higher than the threshold, the duty cycle may be even smaller.

[0077] In an example, the threshold and / or offset may be associated with or correspond to different duty cycle-related information / values and / or operations. Therefore, when the terminal device 110 uses or is instructed to use UL power higher than a certain threshold, the terminal device 110 may then apply the corresponding duty cycle value and / or operation. Similarly, when the terminal device 110 uses / determines and / or is instructed (e.g., via DCI) a certain power control offset, the terminal device 110 may then apply the corresponding duty cycle value and / or operation.

[0078] In another example, using new or existing fields / bits, the corresponding duty cycle information / value can be directly indicated to the terminal device via MAC CE or DCI.

[0079] Thus, it can enable good and dynamic control of the interference level, and more generally enable good and dynamic control of the power level, especially when the terminal device performs transmissions using high power. The above solution is particularly needed when considering simultaneous UL transmissions in the same cell (e.g., for multi-panel UEs) or in different cells. The above solution may also be needed when UL is dynamically switched between different waveforms.

[0080] For illustrative purposes, Figure 3 an example signaling procedure that can be used in some embodiments of the present disclosure is shown. For the purpose of discussion, reference will be made to Figure 1 describe the processing flow 300. It should be understood that although the processing flow 300 has been described with reference to Figure 1 the network environment 100, the processing flow 300 can be equally applied to other similar communication scenarios.

[0081] As Figure 3 shown, the terminal device 110 can be configured 305 via RRC signaling to receive a dynamic indication as to whether the terminal device 110 can use a transmission power greater than a threshold. Next, the network device 120 can send 310 in DCI an indication that the terminal device 110 can use a transmission power greater than the threshold. After receiving this indication, the terminal device 110 can consider 315 that the maximum transmission power can be greater than the threshold, and then determine that the transmission power is greater than the threshold. Thereafter, the terminal device 110 can perform UL transmission using a transmission power greater than the threshold.
