Power control in Long Term Evolution (LTE) is related to many factors, such as path loss, target received power, maximum transmit power, closed-loop power adjustment amount, transmission bandwidth, transmission rate, and the like. In the NR mid-multi-beam scenario, the parameters of partial power control should be beam or transmitted Beam Pair Link (BPL) related.

Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
In a wireless communication system, transmission power control of transmissions is required in order to reduce power consumption of a transmitting device and to reduce interference caused by unnecessary high-power transmissions to other transmissions. Factors such as the size of the communication range, the maximum transmission power and reception sensitivity of the transceiver devices of both communication parties, the modulation and coding scheme and rate of data, the operating frequency band, and the bandwidth occupied by transmission all affect the transmission power. Generally, it is necessary to use a lower transmission power as much as possible under the condition that the received signal quality requirement of the receiving end is satisfied.
In a general communication technique, a communication node 1 transmits a reference signal, and a communication node 2 measures a Path Loss (PL) from the node 1 to the node 2 based on the reference signal. PL is calculated using the difference between the transmission power of the reference signal at node 1 and the reception power of the reference signal received at node 2. Assuming that the PL of the node 2 to node 1 transmission channel is the same as the PL of the node 1 to node 2 channel, the node 2 can calculate the transmission power of the node 2 as the transmitting node to node 1 with the above-mentioned PL. Since PL is the result of a unilateral measurement, this factor belongs to the open loop part in the transmission power. The node 1 receives the transmission and analyzes the transmission, and provides power adjustment information for the node 2 according to the received quality, and the process belongs to closed-loop power control.
In LTE, the base station to terminal link is the downlink and the terminal to base station link is the uplink. The downlink power is determined by the base station based on channel measurements for each scheduled User terminal (UE) and a scheduling algorithm. The power control of the uplink is an open loop combined with a closed loop approach. In addition, certain quantities related to transmission, such as transmission rate, Modulation and Coding Scheme (MCS) level, transmission bandwidth, etc., also affect power.
The following is a formula for calculating the transmission power of a Physical Uplink Shared Channel (PUSCH) of LTE, and each parameter affecting the power is described by taking this as an example, and the PUCCH also has similar parameters and mechanisms.
Figure BDA0001427127420000131
In the above formula, the subscript c refers to a cell, and each Component Carrier (CC) supporting a Carrier Aggregation (Carrier Aggregation) function corresponds to 1 cell. From the above equation, it can be seen that each parameter in the power calculation equation is configured/calculated by differentiating the cell. All descriptions herein are described for 1 CC and thus no specific reference is made to a cell. It should be noted that all parameters of the present application can be extended to multiple CCs, and the power-related configuration and the calculated parameters only need to be configured for each CC independently.
The open loop part of the power PPUSCH of the uplink transmission PUSCH is controlled by the target receiving power P0_PUSCHThe path loss PL and the path loss factor alpha, wherein the target receiving power is divided into cell level and UE level parameters which are determined by the base station and configured to the UE; the closed-loop part is that the base station determines the adjustment amount of closed-loop Power Control according to the difference between the measurement result and the target to Transmit a Transmit Power Control Command (TPC Command for short), that is, a delta for PUSCH in Downlink Control Information (DCI for short)PUSCHAnd δ for a Physical Uplink Control Channel (PUCCH for short)PUSCH) The UE is informed. UE maintains a local power adjustment quantity f (i), updates according to the transmission power control command, and achieves the purpose of closed-loop power control by adopting the formula. Where i is the subframe number. Δ TF is the MCS-dependent power offset, PCMAXIs the maximum power limit, i.e., maximum power, of the UE.
The cell level target received power P0_ nominal of LTE is to distinguish PUSCH (semi-static, dynamic, MSG3) and PUCCH, which correspond to different BLER requirements respectively. The UE level target received power parameter P0_ UE _ specific is also set by distinguishing the above items, and functions to compensate systematic deviations, such as PL estimation errors, errors in absolute output power setting.
Updating f (i) according to the transmission power control command is divided into two modes: the accumulative method is to directly update the local power adjustment amount f (i) of the UE by using the transmission power control command sent by the base station, and the accumulative method is to determine the local power adjustment amount f (i) of the UE by using the transmission power control command sent by the base station and the historical value of the local power adjustment amount of the UE.
Note that f (i) here represents a UE-local closed-loop power adjustment amount, and the UE-local closed-loop power adjustment amount of the PUCCH in LTE is denoted by g (i). Herein, f (i) can also be applied to PUCCH, and the role in the power control process is similar to that applied to PUSCH.
When the base station schedules the uplink transmission of the UE, many factors, including time-frequency resources, transmission rate, modulation and coding scheme, MIMO scheme, etc., need to be determined, and according to the reception quality, the base station needs to determine which factors need to be adjusted for subsequent scheduling, such as improving the modulation and coding scheme, improving the transmission power, etc. But the base station does not know the current transmit power of the UE and whether it can increase it. Therefore, in LTE, there is a mechanism that a UE sends a Power Headroom (PH) to a base station to explicitly inform the distance between the current transmission Power and the maximum transmission Power.
The 5G technology introduces a beam transmission mode, and both the base station and the UE support multiple beams. When operating in beam mode, the power calculation needs to take into account the characteristics of the beam. The invention provides a power control method in a multi-beam mode. The parameters mentioned in the invention are applicable to different channels, such as PUSCH, long PUSCH, short PUSCH, PUCCH, long PUCCH, short PUCCH and signal SRS. The same type of parameters may be configured independently or in combination when applied to each of the above channels or signals. The meaning of the combined configuration means that different channels and signals can share the same value, and the predefined manner or the base station configuration manner determines which different channels and signals can share the same value.
For convenience of description in the embodiment of the present invention, a base station and a UE (user equipment) are used for description, but not limiting the present invention, in an implementation process, the base station and the UE may be replaced by names of various communication nodes, such as nb (nodeb), gNB (gbb), TRP (transmitter receiver point), ap (access point), site, user, STA, relay (relay), and terminal.
The term beam herein means beam or beam group.
Various beam-related concepts are used in the description of the preferred embodiments of the present invention, which are explained below for ease of understanding:

The receiving mode at least comprises one of the following modes: receiving beam, receiving port, receiving resource, reference signal sequence, receiving precoding matrix (analog, digital, mixed mode), and receiver algorithm.
The beam may be a resource (e.g., transmit-side precoding, receive-side precoding, antenna port, antenna weight vector, antenna weight matrix, etc.), and the beam sequence number may be replaced with a resource index, because the beam may be bound to some time-frequency code resources for transmission. A beam may also be a transmission (transmit/receive) mode; the transmission mode may include spatial multiplexing, frequency domain/time domain diversity, etc.
The beam indication means that the transmitting end may indicate that the reference signal (or the reference signal) and the antenna port scanned by the base station or reported by the UE in feedback satisfy a quasi co-location (QCL) assumption through the current reference signal and the antenna port.
The receiving beam refers to a beam of a receiving end which does not need to be indicated, or a beam resource of the receiving end which can be indicated by a quasi co-location (QCL) of a reference signal (or a reference signal) and an antenna port which are scanned by a base station or reported by feedback of the UE through a current reference signal and the antenna port;
the channel characteristics include physical propagation channel characteristics, such as a horizontal transmitting azimuth, a vertical transmitting azimuth, a horizontal receiving azimuth, a vertical receiving azimuth, and the like, and also include characteristics of radio frequency and baseband circuits, such as antenna array characteristics (element pattern), an antenna group, a balance panel, an antenna sub-array (antenna sub-array), a transceiver unit (TXRU), a receiving beam set, an antenna arrangement, and baseband time offset, frequency offset, phase noise, and the like;
the parameters related to the quasi co-location (QCL) at least comprise Doppler expansion, Doppler translation, time delay expansion, average time delay and average gain; and may also include spatial parameter information such as angle of arrival, spatial correlation of received beams, average delay, correlation of time-frequency channel response (including phase information).
The following problems exist in the related art: when the transmission Power of the equivalent omnidirectional radiation Power (EIRP) is used, the calculation of the Power Headroom (PH) of the multi-beam is different from the calculation of the PH in the conventional TRP mode, and a method for solving the problem is not yet available in the current technology; the change of transmission conditions such as beam change, waveform change and the like can cause large change of closed loop power adjustment amplitude, and the existing fixed power adjustment quantity step cannot meet the requirement.

For convenience of understanding the above embodiments, the following description is made by taking a process of configuring a power control related parameter for a UE by a base station as an example.
The base station sends the closed loop power adjustment amount to the UE, and sends bits with a predetermined number of bits, and the power adjustment magnitude represented by the bits needs to be predetermined, for example, 2 bits "00" represents 3dB power boost. The NR introduces a beam transmission mode, and the power adjustment value represented by the bit number of the closed-loop power adjustment quantity needs to be dynamically adjusted. That is, when the condition of the transmission beam changes, for example, the requirement for the closed-loop power adjustment amplitude is large, after several adjustments, the power tends to be stable, and the requirement for the closed-loop power control adjustment amplitude is reduced.
Therefore, more than one set of different value mapping methods of the closed-loop power control adjustment quantity is defined, and at least the functions of large-amplitude fast adjustment (equivalent to the first set of configuration values) and small-amplitude precise adjustment (equivalent to the second set of configuration values) are supported.

The numerology of the transmission changes
The type of traffic transmitted changes
One of the following second conditions or a predefined combination is satisfied, and a second set of value mapping method of the closed-loop power control adjustment amount is enabled, for example, a small-amplitude precise adjustment mapping method is supported.
The magnitude of N consecutive power adjustment amounts is less than or equal to a predefined threshold 1, where N is a predetermined integer greater than or equal to 1.
And the power adjustment quantity exceeding the predefined proportion in the M continuous power adjustment quantities is less than or equal to a predefined threshold 2, and M is a predefined integer greater than or equal to 1.
The value mapping method of the used closed loop power control adjustment quantity can be determined according to the following method:
and the base station indicates the UE to adopt a mapping value taking method of the first set or the second set of closed-loop power control adjustment quantity.
The base station indicates the UE to temporarily adopt a mapping value taking method of the first set or the second set of closed-loop power control adjustment quantity, and indicates an action range, or the action range is predefined, and the action range comprises at least one of the following: valid only for a transmissions, a being a predefined or indicated integer greater than or equal to 1; valid only for B slots, B being a predefined or indicated integer greater than or equal to 1.
The mapping value-taking method of the first set or the second set of closed-loop power control adjustment quantity can be further expanded to support more levels, for example, the mapping methods of the first set, the second set and the third set of closed-loop power control adjustment quantity respectively support functions such as large-amplitude fast adjustment, medium-amplitude adjustment and small-amplitude accurate adjustment.
The above step values can be further extended to different transmission channels/signals, such as for the following signals, channels: and different sets of mapping value-taking methods are respectively defined by the PUSCH, the SRS used for acquiring the CSI, the SRS used for BM, the PUCCH, the short PUCCH and the long PUCCH.
The mapping value-taking method of the closed-loop power control adjustment quantity can be further expanded to different application scenes, such as a fast-moving scene, a slow-moving scene and the like, the base station explicitly configures or the UE judges the current scene according to predefined conditions to determine the mapping value-taking method of the closed-loop power control adjustment quantity.
The large amplitude and the small amplitude in the above description are relative, that is, the closed-loop adjustment amount corresponding to the mapping value method of the first set or the second set of closed-loop power control adjustment amount may use the same overhead, as shown in table 1, or may use different overheads, as shown in tables 2 and 3. Wherein, the closed-loop adjustment quantity of the mapping method of the first set of closed-loop power control adjustment quantity in table 1 is 2 bits, the closed-loop adjustment quantity of the mapping method of the second set of closed-loop power control adjustment quantity is 2 bits, the closed-loop adjustment quantity of the mapping method of the first set of closed-loop power control adjustment quantity in table 2 is 3 bits, the closed-loop adjustment quantity of the mapping method of the first set of closed-loop power control adjustment quantity in table 3 is 1bit, and tables 1, 2 and 3 are as follows:

Optionally, the method is applied to at least one of the following channels: a Physical Uplink Shared Channel (PUSCH), a short PUCCH and a long PUCCH; alternatively, the method is applied to at least one of the following signals: the information sounding reference signal SRS.
Optionally, the method is applied to at least one of the following channels: the PUCCH, short PUCCH, long PUCCH, further includes: determining a PUCCH shared closed-loop power adjustment quantity meeting at least one of the following conditions: short PUCCH and/or long PUCCH which use the same transmission beam resource indication in the same slot; short PUCCH and long PUCCH on different slot slots. Note that, the base station instructs the UE to transmit the SRS using one of the following methods: same transmit power spectral density, same transmit power. For example, the base station transmits the above information in a broadcast manner; a base station transmits UE specific information by using a high-level signaling to indicate an SRS transmission mode of the UE; the base station indicates this information in the PC set.
For the convenience of understanding the above embodiments, the following detailed description is made.
NR supports short PUCCH and long PUCCH. For the same UE, the short PUCCH and the long PUCCH may exist in the same slot, or may exist in different slots. For the same UE, in the same slot, there may be multiple short PUCCHs and multiple long PUCCHs. The Short PUCCH and the long PUCCH may be further classified into different categories according to the length of Uplink Control Information (UCI) to be transmitted, and each category corresponds to a different signal coding scheme. The transmission power needs to be determined for each short PUCCH or long PUCCH, and the complexity of performing open-loop power parameter configuration and closed-loop power control on each category is too high. The invention provides the following scheme, so that a plurality of PUCCHs using the same transmission beam or the transmission beam with similar space channel characteristics share part of parameters of the closed-loop power control process, and the complexity of NR PUCCH closed-loop power control is reduced.
For the power control process of the NR PUCCH, the base station transmits a closed-loop power adjustment amount for the UE, and multiple (i.e., more than 1) PUCCHs that satisfy one or more of the following conditions may share the closed-loop power adjustment amount.
And the UE maintains a local closed loop power adjustment amount g (i) for each power control process (process) or power control loop (loop), wherein i is a slot number. The closed loop power control adjustment amount g (i) may be shared by multiple PUCCHs satisfying one or more conditions, wherein the determination of the conditions may be a predefined manner or a manner in which the base station is configured to the UE. The conditions include:
multiple short PUCCHs within the same slot using the same transmit beam resource indication.
Multiple long PUCCHs in the same slot using the same transmission beam resource indication.
And multiple short PUCCHs with the same UCI length interval in the multiple short PUCCHs indicated by the same transmission beam resource in the same slot. The UCI length interval refers to a length interval divided according to a predefined rule, for example, the UCI length in the short PUCCH is 1-2 bits and is a first type of the short PUCCH, and the UCI length is more than 2 bits and is a second type of the short PUCCH.
And a plurality of long PUCCHs with the same UCI length interval in the plurality of long PUCCHs using the same transmission beam resource indication in the same slot. The UCI length interval refers to a length interval divided according to a predefined rule, for example, a UCI length in a long PUCCH is 1-2 bits and is a first class of the long PUCCH, a UCI length is a second class of the long PUCCH which is greater than 2 bits and less than X bits, a UCI length is a third class of the long PUCCH which is greater than X bits, and the X value is a predefined integer greater than 2. The first, second and third long PUCCHs may share the closed-loop power adjustment amount, or a plurality of long PUCCHs belonging to the first and second classes may share the closed-loop power adjustment amount, or a plurality of long PUCCHs belonging to the second and third classes may share the closed-loop power adjustment amount.
And multiple long PUCCHs with the same time domain repetition time interval in the multiple long PUCCHs indicated by the same transmission beam resource in the same slot. The UCI length interval refers to a length interval divided according to a predefined rule. The time domain repetition time interval refers to the condition that the repetition times meet certain requirements, for example, the repetition times are 1-2 times and belong to the same interval.
And short PUCCH and long PUCCH which are indicated by the same transmission beam resource in the same slot are used.
Short PUCCH of predefined UCI length interval 1 of short PUCCH and long PUCCH of predefined UCI length interval 2 of long PUCCH which are indicated by the same transmission beam resource in the same slot. For example, the UCI length interval 1 is 1-2 bits of UCI length, and the UCI length interval 2 bits is 1-2 bits of UCI length. Or the UCI length interval 2 is a UCI length of 1 to X bits, and X is an integer greater than 1.
Short PUCCH and long PUCCH on different slots.
Short PUCCH of predefined UCI length interval 1 of Short PUCCH and long PUCCH of predefined UCI length interval 2 of long PUCCH on different slots. For example, the UCI length interval 1 is 1-2 bits of UCI length, and the UCI length interval 2 bits is 1-2 bits of UCI length.

Alternatively, in case the method is applied to SRS, the transmission power for SRS is determined by one of the following: determining that all transmission beams of User Equipment (UE) adopt the same power, wherein the power adopts Pcmax to subtract power back-off quantity, and the power back-off quantity is broadcasted by a base station or configured to the UE by the base station; determining that all transmission beams of User Equipment (UE) adopt the same power of a group, wherein each group of power adopts Pcmax to subtract the power back-off of the group, and the power back-off of the group is configured to the UE by a base station according to the beam group of SRS used for beam management; determining that all beams of a user terminal UE adopt the same power, wherein the power is determined by adopting target received power P0 and a PL value, the PL value is determined by the UE or according to the measurement result of a measurement pilot frequency configured by a base station, and P0 is that the base station is configured to the UE; and determining that all beams of the user terminal UE adopt the same power of the group, wherein each group of power is determined by adopting the P0 of the group configured by the base station and the PL value of the group, the base station sets P0 for each group, and the PL of each group is determined by the UE according to the measurement result of the measurement pilot frequency configured by the base station.
For the convenience of understanding the above embodiments, the following detailed description is made.
The transmission power of SRS for BM (SRS for beam management) can be determined by one of the following methods (packet setup and validation time of SRS for beam management):
all beams use the same power Pcmax
All beams use the same power, which uses Pcmax minus a power back-off that is broadcast by the base station or configured by the base station to the UE
All wave beams adopt the same power of the grouping, each group of power adopts Pcmax to subtract the power back-off quantity of the grouping, and the power back-off quantity of the grouping is configured to the UE by the base station according to the wave beam group of SRS for BM
All beams use the same power, which is determined by the P0 and PL values. The PL value is determined by the UE itself or according to the measurement result of the measurement pilot frequency configured by the base station. P0 is the base station configured to the UE.
All beams use the same power for the packet, and each set of power is determined using the packet's P0 and the packet's PL value as configured by the base station. The base station sets P0 for each packet. The PL of each packet is determined by the UE from measurements of measurement pilots configured by the base station.
Calculation timing of PL: the sending time of the trigger information of SRS for BM + X time units. X is a predefined fixed value, or a value related to the configuration of the transmission. For example, different configurations correspond to different values of X. X is an integer of 0 or more.
Optionally, the method further includes: the method comprises the following steps of acquiring power headroom PH of a plurality of transmission beams simultaneously transmitted by a user terminal by the following method: obtaining the PH of each wave beam by subtracting the transmission power Pcmax of the EIRP of each wave beam from the maximum transmission power Pcmax of the equivalent omnidirectional radiation power EIRP of each wave beam in a plurality of wave beams; and obtaining the PH values of the plurality of beams transmitted simultaneously by subtracting the Pcmax value of TRP of Y UEs from the PH value of each beam in the plurality of beams, wherein Y is the number of the plurality of beams transmitted simultaneously minus 1. Through the steps, the calculation method of the PHR is improved, so that the PHR can reasonably reflect the influence of the gains of different beams when the multi-beam is transmitted when the power of the EIRP is adopted.
For the convenience of understanding the above embodiments, the following detailed description is given.
In the NR beam mode, reporting of PHR needs to reflect beam changes. Multiple closed-loop power control loops may exist between the base station and the UE, only one TX beam (group) of the UE may be scheduled at the same time, which corresponds to 1 loop, or multiple TX beams (groups) corresponding to multiple loops may be scheduled, and in addition, the loops at different times may be different. When a plurality of TX beams are simultaneously transmitted, the transmit power of each TX beam can be calculated separately, and the sum of the actual transmit powers is limited by the maximum transmit power of the UE. When the maximum transmit power is not sufficient to meet the transmit power requirements of all TX beams, power reduction may be performed or a portion of the TX beam transmission may be dropped. Therefore, the reported PHR should reflect the distance between the sum power of multiple TX beams (groups) and the maximum power.
In the conventional LTE technology, the transmission Power refers to TRP (Total Radiated Power). In a new generation technology, the transmission Power may be EIRP (equivalent Isotropic Radiated Power). EIRP is a value with a transmission beam directivity gain, and TRP has no transmission beam directivity gain.
The base station transmits downlink signals, such as SSBs (synchronization signal blocks), CSI-RSs (resource indications of CSI-RSs), TRSs (tracking reference signals), etc., in different beams and explicitly or implicitly indicates transmission power of the downlink signals. The UE receives and measures the signals using different beams, and estimates PLs of different BPLs (beam pair links) between the base station and the UE.
The base station may transmit the same type of signals on different beams with equal TRP power and indicate the TRP power of these transmitted signals either explicitly or implicitly. Or the like, or, alternatively,
the base station may transmit the same type of signals in different beams with equal EIRP power and indicate the EIRP power of these transmitted signals either explicitly or implicitly. Or the like, or, alternatively,
the base station may transmit the same type of signals on different beams with equal TRP power and indicate either explicitly or implicitly the EIRP power of these transmitted signals.
The different beams transmit the same type of downlink transmission signals by using the same transmission power according to groups, and indicate the transmission power of each beam group.
In the beam scanning process, a plurality of transmission beams use the same TRP transmission power.
In a scenario supporting multi-beam simultaneous transmission, the UE calculates the transmit power of each beam. In the millimeter wave frequency band, the transmission power of the EIRP is relatively easy to obtain, and when the power value of the transmission beam is the EIRP, the transmission power of each beam calculated by the UE includes the gain of the corresponding beam. Depending on the information available to the UE, the PH of the multi-beam is obtained as follows:
the first method is as follows:
in a scenario supporting multi-beam simultaneous transmission, the UE calculates the EIRP transmit power of each beam and knows the exact beam gain of each transmit beam and Pcmax of the TRP of the UE. The UE obtains the PHs of the multiple beams as follows:
subtracting the beam gain of each wave beam by using the EIRP sending power of each wave beam to obtain the TRP power of the wave beam;
and subtracting the sum of the power of the TRPs of the plurality of beams transmitted simultaneously from the maximum TRP transmission power of the UE to obtain the PH of the plurality of beams transmitted simultaneously.
Examples are as follows: the UE supports 2 beams to transmit simultaneously, and corresponds to two power control processes, or two power loops, respectively.
The EIRP values of the two beams beam1 and beam2 calculated by the UE are respectively as follows: p _ EIRP _ beam1 and P _ EIRP _ beam2, the gains (beam gain) of the two beams are respectively noted as: gain1 and gain 2. Then the TRP powers of the two beams are: p _ TRP _ beam 1P _ EIRP _ beam1-gain1 and P _ TRP _ beam 1P _ EIRP _ beam1-gain 2.
The PH of the two beams is: pCMAX_TRP-(P_TRP_beam1+P_TRP_beam2)=PCMAX_TRP-(P_EIRP_beam1-gain1+P_EIRP_beam2-gain2)
Mode two (corresponding to the above example):
in a scenario supporting multi-beam simultaneous transmission, the UE may calculate EIRP transmit power and know Pcmax of EIRP and Pcmax of TRP of each beam, but may not know an accurate beam gain of each beam. The UE obtains the PHs of the multiple beams as follows:
the EIRP maximum transmit power Pcmax of each beam is subtracted from the EIRP transmit power of that beam to obtain the PH of that beam.
The difference between the sum of PHs of the simultaneously transmitted multiple beams and the sum of Pcmax of TRPs of Y UEs yields the PHs of the simultaneously transmitted multiple beams. Y is the number of simultaneously transmitted beams minus 1.
Subtracting the sum of the TRP powers of the simultaneously transmitted multiple beams by the maximum TRP transmission power of the UE
Examples are as follows: the UE supports 2 beams to transmit simultaneously, and corresponds to two power control processes, or two power loops, respectively.
The EIRP values of the two beams beam1 and beam2 calculated by the UE are respectively as follows: p _ EIRP _ beam1 and P _ EIRP _ beam 2. The EIRP maximum transmit powers of the two beams are: pcmax _ EIRP _ beam1 and Pcmax _ EIRP _ beam 2.
Calculate PH for each beam: PH _ beam1 ═ Pcmax _ EIRP _ beam1-P _ EIRP _ beam 1; PH _ beam2 ═ Pcmax _ EIRP _ beam2-P _ EIRP _ beam 2;
Y=2-1=1;
the PH of the two beams is: (PH _ beam1+ PH _ beam2) -Y × Pcmax _ TRP (PH _ beam1+ PH _ beam2) -Pcmax _ TRP
The third method comprises the following steps:
in a scenario supporting multi-beam simultaneous transmission, the UE may calculate EIRP transmission power and know Pcmax of the TRP of the UE, but may not know the accurate beam gain of each beam, and the beam gain in the above method is replaced with an average beam gain without distinguishing the gains of specific beams. The UE obtains the PHs of the multiple beams as follows:
subtracting the average gain of the type of wave beam from the EIRP sending power of each wave beam to obtain the TRP power of the wave beam;
and subtracting the sum of the power of the TRPs of the plurality of beams transmitted simultaneously from the maximum TRP transmission power of the UE to obtain the PH of the plurality of beams transmitted simultaneously.
The following describes the case where QCL is unchanged in the switching of the width beam.
In the uplink transmission process, the receiving beam switching at the base station side occurs, and if the beams before and after switching are beams with different levels and the same QCL configuration, for example, beams belonging to the same direction and different widths. This situation is likely to be used to calculate PL with the downlink pilot configuration unchanged, e.g., a wide beam of downlink pilots is configured for measurement. The base station needs to indicate the gain difference of the wide and narrow beams to the UE. May be at least one of: updating a P0 value, wherein the P0 value comprises the gain difference of the receiving beams before and after switching; indicating the gain difference of the receiving wave beams before and after switching to the UE through a closed-loop power control adjustment instruction; and indicating the UE to use a temporary large-amplitude step amount, and indicating the gain difference of the receiving beams before and after switching to the UE through a closed-loop power control adjustment instruction, wherein the large-amplitude step amount is only effective at the current moment.
