Background

A New Radio (NR) technology is being established, and as a fifth generation mobile communication system, the new radio technology needs to support many different types of application scenarios, and also needs to support a conventional frequency band, a new high frequency band, and a beam mode at the same time, which brings a great challenge to power control design.

The power of the uplink transmission is related to many factors, such as path loss, target received power, maximum transmit power, closed loop power adjustment, bandwidth of transmission, rate of transmission, etc. The Uplink transmission at least includes a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH), and a Sounding Reference Signal (SRS). And the NR system has the following characteristics: the starting and ending positions of the PUSCH and the PUCCH are not fixed, and different carriers may support different subcarrier intervals, which results in that the slot length is not fixed, the time delay between scheduling/authorization information and scheduled service is not fixed, high priority service supporting Low-delay and high-reliability (URLLC) and non-synchronization between carriers, etc., and results in that a mechanism of Power Headroom Report (PHR) of the NR system is more complicated than that of a Long Term Evolution (LTE) system.

For example, in an NR system, there is a multi-carrier application scenario, and a relevant protocol specifies that, after PHR is triggered, when a new uplink transmission resource is obtained on any one of the multiple carriers, the carrier reports the PHR, and the reported PHR further includes the PHR of each other carrier in the multiple carriers; however, the related art does not provide a method for determining the PHR generation method in these carriers.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.

The first embodiment is as follows:

the present embodiment provides a method for determining a PHR, which may be applied to a User Equipment (UE), or may be applied to other devices that need to report a PHR or need to determine a PHR. The method for determining PHR provided in this embodiment is shown in fig. 1, and includes:

s101: a transmission resource for transmitting the PHR on the first carrier is determined.

It should be understood that the multi-carrier in the present embodiment refers to more than two carrier scenarios, for example, including but not limited to a carrier aggregation ca (carrier aggregation) scenario, and a Dual Connectivity (DC) scenario, which all include multiple carriers. In this embodiment, the carrier may also be referred to as a cell, or a component cell cc (component cell). And it should be understood that one cell (or carrier or CC) in the NR system may contain one or more partial bandwidths bwp (bandwidth part).

In the present embodiment, for convenience of description and understanding, the carrier is illustrated below, and it should be understood that the carrier may also be interchanged with the fractional bandwidth BWP, the cell, and the component cell CC.

The UE sends uplink transmission on a carrier according to the base station configuration or grant. In an application scenario, the uplink transmission includes, but is not limited to, PUCCH transmission, PUSCH transmission, PRACH (Physical Random Access Channel) transmission, and SRS transmission.

In this embodiment, the first carrier in the multiple carriers may be, in an example, a carrier that receives DCI (Downlink Control Information) including scheduling Information of a new uplink transmission first in the multiple carriers after the PHR is triggered. In this embodiment, the second carrier in the multiple carriers may be all the other carriers except the first carrier in the multiple carriers; certainly, in some application scenarios, the second carrier may also be a part of carriers in all other carriers except the first carrier, and it is specifically determined which carriers are the second carriers, and the determination may be flexibly determined according to specific application requirements.

When sending uplink transmission, the UE needs to occupy a certain transmission power, which cannot exceed the limit of the maximum power. For a plurality of uplink transmissions (transmission) with a number greater than 1, when there is an overlap in time (overlapping), a condition that the sum of the power of the overlapped plurality of transmissions is not greater than the maximum power needs to be satisfied. Overlapping in time may refer to multiple transmissions sharing all or part of a period of time, including but not limited to the following multiplexing schemes: Frequency-Division Multiplexing (FDM), Code Division Multiplexing (CDM), and Space Division Multiplexing (SDM). Uplink transmission refers to occupying a specific channel resource to transmit corresponding information, for example, 4 OFDM symbols (hereinafter also referred to as symbols) occupying a PUSCH are required to transmit one data packet, and the 4-symbol PUSCH is referred to as a PUSCH transmission. Similarly, in some application scenarios, there is also transmission of PUCCH, transmission of SRS, transmission of PRACH. There may also be transmission of long PUCCH, transmission of short PUCCH, transmission of long PUSCH, transmission of short PUSCH. There may also be different classes of SRS transmissions.

In some application scenarios, the UE calculates a power headroom ph (power headroom) for PUSCH transmission, PUCCH transmission, and SRS transmission, and reports the power headroom ph (power headroom) to the base station in a PHR manner. The power headroom is the difference between the maximum allowed power and the transmission required power. After the base station obtains the PHR, the base station can obtain the difference between the required power and the maximum power of the current uplink transmission of the UE, thereby improving the subsequent scheduling more efficiently.

In the present embodiment, PHR and PH may be interchanged without being specifically described as not allowed.

In the present embodiment, the virtual PHR is also referred to as a reference PHR, or a PHR of a reference format.

S102: and determining a reference time period of the second carrier according to the determined transmission resource.

As shown in the above analysis, the second carrier in this embodiment may be all the other carriers except the first carrier in the multi-carrier; of course, in some application scenarios, the second carrier may also be a part of the multiple carriers, except the first carrier.

S103: and determining a PHR generation mode of the second carrier according to the uplink transmission or the scheduling information of the uplink transmission of the second carrier in the reference time period.

For example, in one example, determining the PHR generation manner for the second carrier includes, but is not limited to, one of:

determining the PHR as a real PHR based on the real transmission;

the PHR determined based on the reference format, or the reference transmission, or the transmission of the reference format is a virtual PHR.

In an example of this embodiment, the transmission resource for transmitting the PHR on the first carrier includes a transmission time period, and the transmission time period is one of:

time domain resources occupied by uplink transmission including a PHR, wherein the time domain resources refer to a plurality of continuous or discontinuous time units occupied by the uplink transmission, and the time units can be OFDM symbols, slot slots, subframes, frames and the like;

and the first time slot to which the uplink transmission containing the PHR belongs.

In the present embodiment, determining the reference time period of the second carrier according to the determined transmission resource includes, but is not limited to, the following determination manners in several examples.

Example one: determining a reference time period for the second carrier based on the transmission resources, including determining the reference time period for the second carrier based on one of:

a unique slot in the second carrier that overlaps with the transmission time period in a time domain;

a first slot in a second carrier wave overlapped with a time domain of a sending time period;

a first complete slot in a second carrier wave which overlaps with a transmission time period in a time domain;

the last slot in the second carrier wave overlapped with the time domain of the sending time period;

the slot with the most overlapped part is the slot in the second carrier wave overlapped with the time domain of the sending time period;

the first slot with the most overlapped part is the slot in the second carrier wave overlapped with the time domain of the sending time period;

the last slot with the most overlapped part in the slots in the second carrier wave which are overlapped with the transmission time period in a time domain;

orthogonal frequency division multiplexing, OFDM, symbols in a second carrier that overlap in time domain with the transmission time period.

For example, in an application example, a transmission time period for transmitting the PHR on the first carrier is a first slot to which an uplink transmission including the PHR belongs. For ease of understanding, a specific application scenario is illustrated as an example. In this application scenario, it is assumed that the network side or the base station configures carrier aggregation for the UE, and the UE includes 5 carriers (or referred to as cells), which are denoted as CC #1 to # 5. The slot number on CC #1 is slot 1_ x, and x is the serial number of the slot. The slot number on CC #2 is slot 2_ x, x is the serial number of slot, and so on, the slot number on CC #4 is slot 5_ x, x is the serial number of slot.

Suppose that a PHR at the start position CC #2 of slot 2_ n-2 is triggered, and the scheduling information of the first new uplink transmission is slot 1_ n-2 on CC #1, where the scheduling sends an uplink transmission in slot 1_ n, such as PUSCH transmission (or other uplink transmissions may be used as well), which carries the PHR of CC #1 to CC # 5. For CC #1, the PHR includes its true PH, which is calculated from the true PUSCH transmission. For CC #2 to CC #5, whether the respective PHs are real or virtual, and according to which real transmission is calculated, a judgment needs to be made with reference to a time period. That is, in the multi-carrier scenario, after the PHR is triggered, any carrier acquires a new uplink transmission resource, and the PHR is reported, where the reported PHR includes a PHR of each carrier.

The PHR of the CC transmitting the PHR is a real PHR, and whether the PHR of the other CC is a real PHR or a virtual PHR needs to be determined according to whether there is actual uplink transmission in a specific time period.

When actual uplink transmission exists in a specific time period, calculating the PH according to the actual uplink transmission, and reporting a real PHR; otherwise, when there is no actual uplink transmission in a specific time period, calculating the PH according to the reference transmission, and reporting the virtual PHR.

In this embodiment, the specific time period may be the reference time period, or may be a certain time period after or before the reference time period; for example, it may be that a certain second carrier receives DCI including scheduling information (grant information) of new uplink transmission in the reference time period, but only schedules and sends an uplink transmission in a certain specific time period after the reference time period, and according to the specific application scenario requirements, the uplink transmission may also be flexibly used as a basis for calculating the actual PHR of the second carrier, and of course, in some application scenarios, when there is actual uplink transmission in the reference time period of the second carrier, the PH is calculated according to the actual uplink transmission, and the actual PHR is reported; otherwise, when there is no actual uplink transmission in the reference time period, calculating the PH according to the reference transmission for the second carrier, and reporting the virtual PHR.

Referring to fig. 2-1, in a multi-carrier scenario, slot lengths slot numerology of different CCs may be the same or different, and slots of different CCs may be aligned or not aligned.

As shown in fig. 2-1, in this example, the first carrier is CC #1, and a transmission time period for transmitting the PHR on CC #1 is a first slot to which an uplink transmission including the PHR belongs, that is, a padding region in fig. 2-1, at this time, in this example, a reference time period for determining the second carrier (which may be CC #2 to CC #5 in fig. 2-1, or may be a part of CC #2 to CC # 5) according to the transmission resource includes one of the following:

determining a reference time period according to the only slot which has time domain overlapping with the first slot;

determining a reference time period according to a first slot which has time domain overlapping with the first slot;

determining a reference time period according to a first complete slot which has time domain overlapping with the first slot;

determining a reference time period according to the last slot which has time domain overlapping with the first slot;

determining a reference time period according to the slot with the most overlapped part in the slots with time domain overlapping with the first slot;

determining a reference time period according to the first slot with the most overlapped part in slots with time domain overlapping with the first slot;

and determining the reference time period according to the last slot with the most overlapped part in the slots with time domain overlapping with the first slot.

In another example, the transmission time period for transmitting the PHR on the first carrier may also be a time domain resource occupied by an uplink transmission including the PHR. See, for example, fig. 2-2. The first carrier is CC #1, and a transmission time period for transmitting the PHR on CC #1 is a time domain resource occupied by uplink transmission including the PHR, specifically refer to a part of a filling region in fig. 2-2. In this case, an OFDM symbol on the second carrier that overlaps with the time domain resource occupied by the uplink transmission including the PHR on CC #1 may be used as the reference time period in units of OFDM symbols.

In the present embodiment, the reference period determined in the manner shown in the first example may be referred to as a first reference period.

Example two:

in this example, determining the reference time period for the second carrier according to the transmission time period for transmitting the PHR on the first carrier may include:

for the start time of the reference time period of the second carrier, the determination may be made using one of the following:

a reception time of a downlink control signaling DCI containing scheduling information;

the time when the PHR is triggered;

and after the PHR is triggered, the first DCI receiving time containing the scheduling information for scheduling new uplink transmission. The new transmission may be a PUSCH transmission or a PUCCH transmission in this example, where the new transmission is relative to the retransmission and may also be referred to as an initial transmission.

Because the reliability of the virtual PHR is worse than that of the real PHR, the reporting probability of the real PHR can be increased as much as possible. If only the time domain resource occupied by the PHR uplink transmission or the slot to which the PHR uplink transmission belongs is considered, the probability of true transmission possibility of other CCs is relatively small. If the reference time period of the decision is reasonably prolonged, the true transmission probability of other CCs is increased; therefore, the starting time of the reference time period of the second carrier is determined by adopting one of the above modes, so that the reference time period of the decision can be reasonably prolonged, and the real transmission probability of other CCs is improved.

In this example, determining the end time of the reference period according to the transmission period may include, but is not limited to:

determining the end time of the reference time period according to the end point of the sending time period (including the time domain resource occupied by the uplink transmission of the PHR or the first time slot belonging to the uplink transmission of the PHR);

or, determining an end time of the reference time period according to one of:

an end point of a unique slot in a second carrier wave which has time domain overlapping with the sending time period;

an end point of a first slot in a second carrier wave which has time domain overlapping with the sending time period;

an end point of a first complete slot in a second carrier wave which has time domain overlapping with the sending time period;

an end point of the last slot in the second carrier wave with time domain overlapping with the sending time period;

an end point of a slot with the most overlapped part in slots in the second carrier wave which has time domain overlapping with the sending time period;

the end point of the first slot with the most overlapped part in the slots in the second carrier wave which has time domain overlapping with the sending time period;

the end point of the last slot with the most overlapped part in the slots in the second carrier wave which has time domain overlapping with the sending time period;

and the last OFDM symbol in the second carrier wave with time domain overlapping with the transmission time period.

For example, in an application scenario, a time point when the PHR is triggered may be used as a start time of the reference time period, and an end time of the reference time period may also be flexibly set. For example, referring to the reference period shown in the filling region of fig. 3-1, a time point at which the PHR is triggered is taken as a start time of the reference period, and an end point of the first slot is taken as an end time of the reference period. For another example, referring to the reference time period shown in the filling region in fig. 3-2, the time point when the PHR is triggered may be used as the start time of the reference time period, and the end point of the time domain resource occupied by the uplink transmission including the PHR may be used as the end time of the reference time period. Which of the manners shown in fig. 3-1 and 3-2 the reference time period specifically takes can be flexibly set according to a specific application scenario.

In addition, since the interval between the scheduling information grant information and the PUSCH may span several slots, for PHR calculation of other CCs, if only the transmission time period of the PUSCH or the slot where the transmission time period is located is used as a reference time period to determine whether real transmission overlaps with the transmission time period, the probability of real transmission is relatively low. Thus, in another example, the time when the DCI containing the scheduling information is received may be used as the starting time of the reference time period, or the time when the first DCI containing the scheduling information scheduling a new PUSCH transmission is received may be used as the starting time of the reference time period after the PHR is triggered; the end time for the reference period can also be flexibly set. For example, referring to the reference time period shown in the filling region in fig. 3-3, the time when the DCI including the scheduling information is received is taken as the start time of the reference time period, and the end point of the time domain resource occupied by the uplink transmission including the PHR is taken as the end time of the reference time period. For another example, see the reference time period shown in the filling region in fig. 3 to 4, to use the time when the DCI containing the scheduling information is received as the starting time of the reference time period, and to use the ending point of the first slot as the ending time of the reference time period.

In this embodiment, the reference period determined in the manner shown in the second example may be referred to as a second reference period.

Example three:

in this example, the determination manner of the starting time of the reference time period of the second carrier may adopt, but is not limited to, the manner in the above-mentioned second example, and the confirmation manner of the ending time of the reference time period may adopt, but is not limited to, one of the following manners:

determining the end time of the reference time period in advance of a first time interval according to the starting point of the sending time period (the time domain resource occupied by the uplink transmission containing the PHR or the first time slot belonging to the uplink transmission containing the PHR);

or, determining an end time of the reference time period according to one of:

the starting point of the only slot in the second carrier wave which has time domain overlapping with the sending time period is advanced forward by a second time interval;

the starting point of the first slot in the second carrier wave which has time domain overlapping with the sending time period advances a second time interval forward;

the starting point of the first complete slot in the second carrier wave which has time domain overlapping with the sending time period is advanced forward by a second time interval;

the starting point of the last slot in the second carrier wave which has time domain overlapping with the sending time period is advanced forward by a second time interval;

in the slots in the second carrier wave which has time domain overlapping with the sending time period, the starting point of the slot with the most overlapping part is advanced forward by a second time interval;

in the slots in the second carrier wave which are overlapped with the sending time period in the time domain, the starting point of the first slot with the most overlapped part is advanced forward by a second time interval;

in the slots in the second carrier wave which are overlapped with the sending time period in the time domain, the starting point of the last slot with the most overlapped part is advanced forward by a second time interval;

the first OFDM symbol in the second carrier having time domain overlap with the transmission time period is advanced forward by a second time interval.

In one example, at least one of the first time interval and the second time interval may be a preset time length or a time length determined according to a capability of the user equipment UE; for example, the first time interval and the second time interval may be determined by N2. Where N2 is the minimum time required for the UE to process the uplink transmission.

For example, in an application scenario, refer to the reference time period shown in the filling region in fig. 4-1, take the time when the DCI including the scheduling information is received as the start time of the reference time period, and advance the end point of the time domain resource occupied by the uplink transmission including the PHR forward by a first time interval as the end time of the reference time period;

for another example, in an application scenario, referring to the reference time period shown in the padding region in fig. 4-2, the time when the DCI including the scheduling information is received is taken as the starting time of the reference time period, and the ending point of the first slot is advanced forward by a second time interval to be taken as the ending time of the reference time period;

for another example, in an application scenario, referring to the reference time period shown in the filled region in fig. 4-3, the time point when the PHR is triggered is taken as the start time of the reference time period, and the end point of the first slot is advanced forward by a second time interval as the end time of the reference time period.

In the present embodiment, the reference period determined in the manner shown in the third example may be referred to as a third reference period.

As can be seen from the above examples, the manner of confirming the start point and the end point of the reference time period in the present embodiment may adopt any combination of the above example manners, and is not limited to the above example manners.

In an example of this embodiment, determining, according to the uplink transmission or the scheduling information of the uplink transmission of the second carrier in the reference time period, a generation manner of the PHR of the second carrier may include, but is not limited to: determining the PHR of the second carrier as a true PHR when at least one of the following conditions is satisfied:

whether uplink transmission exists in the reference time period;

whether DCI including scheduling information for uplink transmission exists (i.e., received) in the reference period.

Of course, it should be understood that the uplink transmission or the scheduling information of the uplink transmission is not limited to the two cases of the above example, and can be flexibly adjusted and set according to specific application scenarios and requirements.

For ease of understanding, the present embodiment is described below in terms of several specific application examples.

For example, in an application example, for dynamically scheduled uplink transmission, when there is a corresponding DCI carrying grant information (i.e., scheduling information):

for a certain second carrier, when the received DCI carrying grant information earlier than the start time of a second reference time period and the scheduled transmission of the grant information is within the second reference time period, determining that the real PHR of the uplink transmission can be reported, that is, determining that the PHR of the second carrier is the real PHR; otherwise, determining that the real PHR of the second carrier cannot be reported, that is, determining that the PHR required to be reported for the second carrier is a virtual PHR.

For another example, in an application example, for dynamically scheduled uplink transmission, corresponding DCI carries grant information, whether a PHR of the type of uplink transmission is reported as a real PHR may be determined according to whether the transmitted DCI is received in a third reference time period, for example:

when a certain second carrier receives DCI carrying grant information of uplink transmission of dynamic scheduling and the receiving time is within a third reference time period, the real PHR of the uplink transmission can be reported; namely determining the PHR of the second carrier wave as a real PHR; and when the DCI carrying the dynamically scheduled transmission grant information is not in the third reference time period, determining that the real PHR of the second carrier cannot be reported, that is, determining that the PHR required to be reported for the second carrier is a virtual PHR.

In an application scenario, for URLLC transmission, because there is a very low delay requirement, it is likely that the DCI including the grant information is very close to the actual URLLC transmission, the usage rule of the third reference time period may be adopted, and as long as the DCI including the grant information is received in the third reference time period, that is, a period of time before the transmission start point including the PHR, the true PHR of the URLLC transmission may be reported.

For ease of understanding, the present embodiment is further exemplified in the following exemplary manner.

The first method is as follows:

in this manner, when it is determined that there is actual transmission within a reference time period, optionally, the following may be further set: there is a transmission within the reference period, and if the transmission is grant based scheduled, the grant information is received early enough so that there is an actual transmission within the reference period.

In this manner, when the reference time period is one of the following, whether the PHR is a real PHR or a virtual PHR may be determined according to whether uplink transmission exists in the reference time period:

a transmission time period of the first carrier;

the first reference time period;

the above-mentioned second reference period;

the third reference period.

Wherein the starting time of the second reference time period and/or the third reference time period may be determined according to one of the following: a reception time of a downlink control signaling DCI containing scheduling information; the time at which the PHR is triggered; and after the PHR is triggered, the first DCI receiving time containing the scheduling information for scheduling new uplink transmission.

For example, the start time of the extended reference period is a time when the PHR is triggered. The starting time of the extended time period is the receiving time of the first DCI containing the scheduling information for scheduling the new uplink transmission after the PHR is triggered.

When the memory in the reference time period is transmitted in the uplink, the PHR is a real PHR; and when the uplink transmission does not exist in the reference time period, the PHR is a virtual PHR.

Optionally, determining whether the PHR is a real PHR or a virtual PHR according to whether there is uplink transmission in the reference time period includes, but is not limited to, at least one of:

the reference time period memory is transmitted in an uplink, and the transmission is based on scheduling, and scheduling information of the transmission is received before a preset first reference time, so that the PHR is a real PHR;

if there is no uplink transmission in the reference time period, the PHR is a virtual PHR;

the reference time period has uplink transmission, and the transmission is based on scheduling, and the scheduling information is received after the first reference time, so the PHR is a virtual PHR;

there is an uplink transmission within the reference time period and the transmission is a non-scheduling based transmission, then the PHR is a true PHR.

Wherein the first reference moment may be determined according to one of: a start time of a transmission including the PHR, and a scheduling information reception time of the transmission including the PHR.

Optionally, the first reference time may also be determined according to one of the following: the start time of the transmission including the PHR is advanced by a third time interval and the scheduling information reception time of the transmission including the PHR is advanced by a fourth time interval.

Wherein the third time interval or the fourth time interval is a predefined time interval, or a time interval configured by the base station, or a time interval determined by the capability of the UE.

When the results of the real PHR and the virtual PHR are determined to have conflict, the results of the virtual PHR are ignored with the real PHR as the reference.

The second method comprises the following steps:

in addition to the case where the above-described mode is exemplified, the present mode is exemplified in another case. For example, grant information arrives early enough, but the actual transmission is not within the reference period described in manner one. Since there is no transmission required to define an interval, the grant information cannot define only one time point as in the first mode, and thus a time interval may be defined in the first mode.

In this example, when the reference time period is a fourth reference time period, it may be set to determine whether the PHR is a real PHR or a virtual PHR according to whether uplink transmission scheduling information exists in the fourth reference time period.

Wherein the fourth reference time period is: and starting time of the second reference time period and/or the third reference time period to the first reference time.

The second reference time period and/or the third reference time period and the first reference time are/is identical to those described in the first mode.

For example, when there is scheduling information for uplink transmission in the fourth reference time period, the PHR is a real PHR; and when the scheduling information of uplink transmission does not exist in the fourth reference time period, the PHR is a virtual PHR.

In this embodiment, the first mode may be implemented independently, or the second mode may be implemented in combination. When the first mode and the second mode are implemented in a combined manner, optionally, if the PHR is determined to be a real PHR by any one of the first mode and the second mode, the PHR is determined to be a real PHR; and when the PHR is determined to be the virtual PHR in the first mode and the second mode, determining that the PHR is the virtual PHR.

When the mode one and the mode two are determined as the real PHR and the transmission corresponding to the real PHR determined by the mode one and the mode two is different, the transmission corresponding to the real PHR may be determined in one of the following modes but is not limited to the following modes:

transmitting corresponding to the determined real PHR in a first mode;

the transmission corresponding to the real PHR determined by the mode two;

the earliest transmission in the transmissions corresponding to the real PHR determined by the first mode and the second mode;

the latest starting transmission in the transmission corresponding to the real PHR determined by the first mode and the second mode;

the earliest transmission of scheduling information in the transmission corresponding to the real PHR determined by the first mode and the second mode;

and the latest transmission of the scheduling information in the transmission corresponding to the real PHR determined by the first mode and the second mode.

The method for determining the PHR provided by this embodiment can definitely determine whether the PHR is real or virtual, and increase the reporting probability of the real PHR as much as possible; the most reasonable transmission among the plurality of transmissions in the eligible time period is selected for calculation of the PHR.

Example two:

for convenience of understanding, the present embodiment is exemplified by combining several cases of the scheduling information of the uplink transmission or the uplink transmission of the reference time period of the second carrier on the basis of the above embodiments.

In this embodiment, determining whether the PHR of the second carrier is a real PHR or a virtual PHR according to the scheduling information of the uplink transmission or the uplink transmission of the second carrier in the reference time period includes:

determining that the PHR of the second carrier is a true PHR when determining that the uplink transmission or the scheduling information of the uplink transmission meets at least one of the following requirements;

the memory of the reference time period is transmitted in an uplink;

the reference time period includes DCI including scheduling information for uplink transmission.

In an example of this embodiment, when there are one or more uplink transmissions in the reference time period of the second carrier, the generating manner of the PHR may be determined according to at least one of the uplink transmissions, scheduling information of the uplink transmissions, and types of the uplink transmissions. The types of uplink transmissions in this example include, but are not limited to, grant-based uplink transmissions, uplink transmissions without dynamic grants.

For example, when there are one or more uplink transmissions in the reference time period, the generating manner of the PHR may be determined according to the uplink transmissions and/or the scheduling information of the uplink transmissions, including determining the true PHR of the second carrier according to at least one of the following:

earliest starting uplink transmission;

the latest starting uplink transmission;

uplink transmission corresponding to the scheduling information received earliest;

and uplink transmission corresponding to the scheduling information received at the latest.

In an example of this embodiment, for multiple grant-based uplink transmissions, the uplink transmission of the real PHR may be determined and calculated according to the scheduling information receiving time corresponding to the uplink transmission. For example, the uplink transmission corresponding to the earliest received scheduling information or the uplink transmission corresponding to the latest received scheduling information is selected among the multiple grant-based uplink transmissions.

In an example of this embodiment, for a plurality of uplink transmissions without dynamic grant, the uplink transmission of the real PHR is determined and calculated according to the start time of the uplink transmission. For example, the earliest starting uplink transmission or the latest starting uplink transmission is selected among a plurality of uplink transmissions that do not require dynamic grants.

In an example of this embodiment, for uplink transmission based on grant and uplink transmission without dynamic grant both meeting the real PHR calculation requirement, the uplink transmission based on dynamic grant is selected to calculate the real PHR.

Or, for the uplink transmission based on dynamic authorization and the uplink transmission without dynamic authorization meeting the real PHR calculation requirement, selecting the uplink transmission without dynamic authorization to calculate the real PHR.

That is, under the condition that both the grant-based uplink transmission and the uplink transmission without dynamic grant exist, one transmission based on dynamic grant is selected from the plurality of grant-based uplink transmissions according to the above principle, one transmission without dynamic grant is selected from the plurality of uplink transmissions without dynamic grant, and finally one uplink transmission is determined for calculation of the PHR from the selected transmission based on dynamic grant and the transmission without dynamic means.

For convenience of understanding, the following description of the present embodiment describes an example of a scheduling method for uplink transmission: the uplink transmission may be dynamically scheduled by uplink grant information (UL grant) included in the physical layer downlink control information, or may be semi-statically scheduled. The former is called grant based transmission (grant based transmission); the latter is called transmission without dynamic grant (grant free transmission), also called transmission of configured grant (configured grant). The transmission of configuration grants falls into two categories: for type1 transmissions, all grant information is configured for higher layer signaling; for type2 transmissions, the higher layer signaling configures a portion of the authorization information, and also a portion of the authorization information is sent via physical layer control signaling, which is valid for several transmissions.

The scheduling information in the embodiments of the present invention may also be referred to as grant information (grant) or uplink grant information (UL grant).

For grant based transmission, one DCI may schedule one PUSCH transmission; for transmission of the configuration grant of type2, one DCI may schedule several PUSCH transmissions.

In an example of this embodiment, when one or more DCIs including scheduling information of uplink transmission exist in a reference time period, a generation manner of the PHR is determined according to the scheduling information of uplink transmission.

For example, when one or more DCIs including scheduling information of uplink transmission exist in a reference time period, determining a generation manner of a PHR according to the scheduling information of uplink transmission includes calculating a true PHR of a second carrier according to at least one of:

In an example of this embodiment, when there is uplink transmission without dynamic grant and uplink transmission based on grant within the reference time period, the true PHR of the second carrier may be calculated according to at least one of:

uplink transmission corresponding to scheduling information received latest in authorized uplink transmission;

there is no need for the latest starting uplink transmission among the dynamically granted uplink transmissions.

For example, the real PHR is calculated with the uplink transmission corresponding to the DCI received latest in the authorized uplink transmission or with the uplink transmission starting latest in the uplink transmission without dynamic authorization; or, selecting one uplink transmission from the uplink transmission corresponding to the DCI received latest in the authorized uplink transmission and the uplink transmission started latest in the uplink transmission without dynamic authorization to calculate the true PHR, where the selection rule may be according to the start time of the uplink transmission or a random selection rule.

Optionally, in one of the embodiments, the priority for the PHR may be set by at least one of the following:

the real PHR priority based on the PUSCH is higher than that based on the SRS;

the real PHR priority based on PUSCH is higher than the virtual PHR priority based on SRS;

the PUSCH-based virtual PHR has a higher priority than the SRS-based virtual PHR;

the priority of the PUSCH-based true PHR of the uplink UL is higher than the priority of the PUSCH-based true PHR of the supplemental uplink SUL;

the priority of the UL SRS-based real PHR is higher than that of the SUL SRS-based real PHR;

the priority of the PUSCH-based real PHR of the UL is higher than that of the SRS-based real PHR of the SUL.

In this embodiment, UL may be referred to as non-SUL, as opposed to SUL. In another application example in the present embodiment, the priority of the PHR may also be set by at least one of the following:

the priority of the PUSCH-based real PHR of the SUL is higher than that of the UL PUSCH-based real PHR;

the priority of the SRS-based real PHR of the SUL is higher than that of the UL SRS-based real PHR;

the priority of the PUSCH-based real PHR of the SUL is higher than that of the SRS-based real PHR of the UL.

In an example of this embodiment, when it is determined that the PHR of the second carrier is a true PHR, the method may further include:

when the PUSCH transmission and the SRS transmission exist in the reference time period, calculating the real PHR of the second carrier wave according to the PUSCH transmission, namely determining that the priority of the type1PHR corresponding to the PUSCH transmission is higher than the priority of the type1PHR of the SRS transmission.

when Supplementary Uplink (SUL) transmission and uplink (Up Link, UL) transmission exist within the reference time period, the true PHR of the second carrier is calculated according to the UL transmission, that is, it is determined that the PHR priority of the UL is higher than the PHR priority of the SUL.

In an example of this embodiment, when it is determined that the PHR of the second carrier is a true PHR, the method may further include: when there are one or more uplink transmissions in the reference time period, at least one uplink transmission may be selected in a front-to-back selection manner to determine to calculate the true PHR of the second carrier according to, but not limited to, any of the following orders:

time priority (i.e. time priority) of uplink transmission, type priority (i.e. PHR type) of uplink transmission, priority of SUL/UL; that is, the time priorities of the plurality of uplink transmissions are judged first, and if the time priority of a certain uplink transmission is the highest, the uplink transmission with the highest time priority is directly adopted as a calculation basis; otherwise, judging the type priority of uplink transmission, and finally judging the priority of SUL/UL; the latter combination orders are analogized;

SUL/UL priority, uplink transmission time priority, and uplink transmission type priority;

SUL/UL priority, uplink transmission type priority, and uplink transmission time priority.

Of course, in addition to the order of the above examples, the following combination of priority orders may be included but not limited to:

time priority of uplink transmission, priority of SUL/UL and type priority of uplink transmission;

the type priority of uplink transmission, the time priority of uplink transmission and the priority of SUL/UL;

the type priority of uplink transmission, the priority of SUL/UL and the time priority of uplink transmission.

In this embodiment, the time priority of uplink transmission refers to a priority differentiated from time to time, and includes but is not limited to one of the following: the priority of the early transmission starting time is high, and the priority of the early transmission scheduling information receiving time is high.

The time priority of the uplink transmission may also include, but is not limited to, one of: the later transmission start time has a higher priority, and the later time when the transmitted scheduling information is received has a higher priority.

The type priority of the uplink transmission refers to the priority distinguished from the type of the uplink transmission, and comprises one of the following:

the transmission is that the priority of the PHR of the PUSCH is higher than the priority of the PHR of the SRS;

the transmission is a PHR of the PUCCH with higher priority than the transmission is a PHR of the PUSCH.

The priority of SUL/UL means that when the frequency domain resource where the uplink transmission is located belongs to SUL and UL, there are different priorities, including but not limited to one of the following:

the transmission sent in the UL has a higher priority than the transmission sent in the SUL;

the transmission sent in the SUL has a higher priority than the transmission sent in the UL.

It can be seen that, in the embodiment, when determining and calculating the PHR, the corresponding PHR may be flexibly determined according to the specific uplink transmission condition in the reference time period, and the determination manner is flexible and reliable.

Example three:

in the NR system, 5 types of PUCCH are included, which are PUCCH format 0, PUCCH format 1, PUCCH format 2, PUCCH format 3, and PUCCH format 4, respectively. The format 0 and 2 time domains occupy 1 to 2 OFDM symbols, called short PUCCH. Format 1, format 3, format 4 occupy 4 to 14 OFDM symbols, called long PUCCH. The long PUCCH and the short PUCCH may be configured in one slot.

In this embodiment, the PHR calculated for PUCCH transmission is referred to as Type2 PHR. To distinguish between the existing PHR of type1 calculated for PUSCH transmission and the PHR of type 3 calculated for SRS transmission. Of course, the PHR calculated for PUCCH transmission may also be referred to as other type of PHR.

In this embodiment, in a multi-carrier scenario, only one carrier may have PUCCH configured, or multiple carriers may have PUCCH configured, and in this embodiment, it may be determined whether a corresponding PHR is a real PHR or a virtual PHR only for the carrier configured with PUCCH.

For a certain carrier, if PUCCH is configured, PUCCH-related PHR, also referred to as a second-type PHR, is reported, and even if the carrier does not actually transmit in the reference period, a virtual type2 PHR needs to be reported. Thus, PHR in various embodiments of the present invention includes, but is not limited to, at least one of:

PHR related to physical uplink shared channel PUSCH transmission;

PHR related to physical uplink control channel PUCCH transmission.

In the present embodiment, when the PUCCH and the PUSCH are frequency division multiplexed on at least one symbol, the true PHR of type2 may calculate the PH based on the PUCCH transmission and the PUSCH transmission. When there is no frequency division multiplexing on PUCCH and PUSCH, then the real PHR for type2 may not consider PUSCH transmission.

In this embodiment, when there is a real PUCCH transmission in a certain carrier within a reference time period, PH may be calculated based on the reference PUCCH transmission calculation, i.e., assuming some power calculation related parameters.

In this embodiment, when there is no real PUSCH transmission for a certain carrier within a reference time period, the PH is calculated based on a reference PUSCH transmission calculation, i.e. assuming some power calculation related parameters.

In this embodiment, when the second carrier is configured with PUCCH transmission, determining a PHR of the second carrier related to the PUCCH may be further included.

For example, in one example of the present embodiment, determining the PHR of the second carrier related to the PUCCH may include:

when there is a long PUCCH transmission and a short PUCCH in the reference period of the second carrier, determining the reported PHR in at least one of the following manners:

determining that the reported PHR comprises a PHR transmitted by a long PUCCH and a PHR transmitted by a short PUCCH;

and determining that the reported PHR comprises the PHR of the long PUCCH transmission and the average value of the PHR of the short PUCCH transmission.

For another example, in an example of the present embodiment, the PHR of the second carrier related to the PUCCH may include:

when long PUCCH transmission and short PUCCH exist in a reference time period, determining the reported PHR from high to low by adopting at least one of the following priority orders:

determining reported PHR according to the sequence of the real PHR of the long PUCCH, the real PHR of the short PUCCH and the priority of the virtual PHR from top to bottom;

or the like, or, alternatively,

and determining the reported PHR according to the real PHR of the short PUCCH, the real PHR of the long PUCCH and the virtual PHR from top to bottom in priority.

For another example, in an example of the present embodiment, the PUCCH related PHR of the second carrier may include:

when PUCCH transmission and PUSCH transmission exist in a reference time period, according to whether time domain overlapping exists between long PUCCH transmission and short PUCCH transmission of PUCCH transmission and PUSCH transmission, a reported PHR may be determined in order from high to low according to the following priority:

if the long PUCCH transmission and the PUSCH transmission have time domain overlapping, and the short PUCCH transmission and the PUSCH transmission have no time domain overlapping, determining to report PHR corresponding to the long PUCCH transmission;

if the short PUCCH transmission and the PUSCH transmission have time domain overlapping, and the long PUCCH transmission and the PUSCH transmission have no time domain overlapping, determining to report a PHR corresponding to the short PUCCH transmission;

if the long PUCCH transmission and the short PUCCH transmission are overlapped with the PUSCH transmission in the time domain, or the long PUCCH transmission and the short PUCCH transmission are not overlapped with the PUSCH transmission in the time domain, the reported PHR is determined by adopting at least one of the following modes from high priority order to low priority order:

or the like, or, alternatively,

In an example of this embodiment, when the PUCCH and PUSCH have partial time domain overlap, the PUCCH-related PHR is determined according to the time domain overlap portion of the PUCCH and the PUSCH.

For example, when one PUCCH transmission has partial time domain overlap with the PUSCH transmission, the PHR related to the PUCCH may be determined according to 3 parts: the PHR related to the PUCCH determined according to the time domain overlapping part of the PUCCH and the PUSCH, and the PHR related to the PUCCH determined according to the time domain overlapping part of the PUSCH. The three time domain intervals correspond to the first, second and third portions of fig. 5, respectively.

In one example, the PHR related to PUCCH may be determined from high to low in priority order as follows:

a PHR related to the PUCCH determined according to a time domain overlapping portion of the PUCCH and the PUSCH,

according to the PHR related to the PUCCH which is not determined by the time domain overlapping part of the PUSCH in the transmission time of the PUCCH,

and determining the PHR related to the PUCCH according to the time domain overlapping part of the PUCCH within the transmission time of the PUSCH.
