Description

[Technical Field]

[0001] This disclosure generally pertains to wireless communications. In particular, this disclosure relates to methods, devices, and systems for determining statistical information. [Background technology]

[0002] background Wireless communication technology is driving the world towards an increasingly connected and networked society. High-speed and low-latency wireless communication relies on efficient network resource management and allocation between user equipment and wireless access network nodes (including, but not limited to, base stations). Next-generation networks are expected to provide high-speed, low-latency, and ultra-high-reliability communication capabilities, meeting the requirements of various industries and users.

[0003] In a wireless communication system, user equipment (UE) may have the capability to support one or more power classes different from the band's default UE power class, and the supported power classes may enable higher maximum output power than the default power class. If the percentage of uplink symbols transmitted during a certain evaluation period (e.g., duty cycle) is greater than a threshold (e.g., maximum duty cycle), the UE may apply all the requirements for the default power class to the supported power class. There are various problems / challenges associated with this implementation. For example, one problem / challenge is that when the evaluation period is one radio frame or longer, the base station may not know the exact evaluation period used by the UE, nor the duration of the default power class applied, which may lead to some ambiguity issues regarding uplink power control. Another problem / challenge is that when non-overlapping subband full-duplex is applied, where the uplink subband is introduced into the downlink or flexible symbols, there may be uncertainty in how to calculate the percentage of uplink symbols transmitted during a certain evaluation period.

[0004] This disclosure describes various embodiments for determining statistical information, addressing at least one of the issues / challenges discussed herein. [Overview of the project] [Means for solving the problem]

[0026] This disclosure describes methods and devices for determining statistical information.

[0027] Next-generation (NG) mobile communication systems are driving the world toward an increasingly connected and networked society. High-speed and low-latency wireless communications depend on efficient network resource management and allocation between user equipment and wireless access network nodes (including, but not limited to, wireless base stations). Next-generation networks are expected to provide high-speed, low-latency, and ultra-high-reliability communication capabilities, meeting the requirements of various industries and users.

[0028] Fourth-generation mobile communication technology (4G), Long-Term Evolution (LTE), or LTE-A, and fifth-generation mobile communication technology (5G) are facing increasing demand. Based on current development trends, 4G and 5G systems are developing support for advanced mobile broadband (eMBB), ultra-high reliability low-latency communication (URLLC), and massive machine-type communication (mMTC) capabilities. In some implementation forms, coverage expansion may be a requirement for 4G, 5G, and / or further generations of communication systems.

[0029] In a wireless communication system, a user equipment (UE) may have the capability to support one or more power classes different from the band's default UE power class, and the supported power classes may enable higher maximum output power than the default power class. If the percentage of uplink symbols transmitted during a certain evaluation period (e.g., duty cycle) is greater than a threshold (e.g., maximum duty cycle), the UE may apply all the requirements for the default power class to the supported power class. There are various problems / challenges associated with this implementation. For example, one problem / challenge is that while the evaluation period is one radio frame or longer, the base station (or wireless communication node) may not know the exact evaluation period used by the UE, nor the duration of the default power class applied, which may lead to some ambiguity issues regarding uplink power control. Another problem / challenge is that when non-overlapping subband full-duplex is applied, where the uplink subband is introduced into the downlink or flexible symbols, there may be uncertainty in how to calculate the percentage of uplink symbols transmitted during a certain evaluation period.

[0030] This disclosure describes various embodiments for determining statistical information, addressing at least one of the issues / challenges discussed herein.

[0037] This disclosure describes various embodiments for determining statistical information that may be implemented, in part or in whole, in the network base station and / or user equipment described above in FIGS. 2-3. Various embodiments in this disclosure may enable efficient wireless transmission in a telecommunication system, which may improve resource utilization efficiency and / or the latency performance of URLLC traffic.

[0038] In some implementations of a wireless communication system, in the case of a single uplink (UL) carrier, the UE may be permitted to set its configured maximum output power P CMAX,f,c for carrier f of serving cell c. The configured maximum output power P CMAX,f,c may be set within the following boundaries, i.e., P CMAX_L,f,c ≦P CMAX,f,c ≦P CMAX_H,f,c where P CMAX_L,f,c and P CMAX_H,f,c depend on P PowerClass and P PowerClass,c is a linear value of the maximum UE power regarding serving cell c or ue-PowerClass without considering tolerances.

[0039] In some implementations of wireless communication systems, for uplink (UL) carrier aggregation (CA), the UE is configured for the serving cell c with a maximum output power P CMAX,c The total maximum output power P configured therewith CMAX It may be permitted to set the total maximum output power P. CMAX The following boundary, namely, P CMAX_L ≤P CMAX ≤P CMAX_H It may be set internally, and here, P CMAX_L and P CMAX_H P PowerClass,CA Depends on P PowerClass,CA The maximum power class (PC) may be PC2, and the power usable with UL CA is P PowerClass,CA It is restricted by P. In some cases, PowerClass,CA This is also known as UL CA's aggregated power, 10log 10 Σp PowerClass,c It is replaced by, here, P PowerClass,c This is a linear value of the maximum UE power with respect to serving cell c or ue-PowerClass, without considering tolerances.

[0040] In some implementations, power headroom (PHR) calculations can be performed as follows: [ka]

[0041] Here, P CMAX,f,c (i) is the maximum output power configured for the carrier f of the serving cell c in the PUSCH transmission opportunity i. [ka] This relates to the open-loop power control parameters, [ka] And, [ka] This is determined by P0-PUSCH-AlphaSet and SRI indication, PL b,f,c (q d ) is the reference signal (RS) index q for the active DL BWP of carrier f of serving cell c. d This is the downlink path loss estimate in dB calculated by UE using [the specified method].

[0042] Here, f b,f,c (i,l) relates to the closed-loop power control parameter. Push power control adjustment state f with respect to the active UL BWP b of the carrier f of serving cell c in Push transmission opportunity i. b,f,c (i,l) [ka] Regarding this.

[0043] [ka]

[0044] Here, [ka] This is a Transmission Power Control (TPC) command value included in DCI format 0_0 or DCI format 0_1 ​​that schedules a push transmission opportunity i in the active UL BWP b of the carrier f of serving cell c.

[0045] Here, [ka] μ is the bandwidth of the push resource allocation, represented by the number of resource blocks for the push transmission opportunity i in the active UL BWP b of the carrier f of serving cell c, and μ is the SCS configuration. It is the number of resource blocks (RBs) for push, reflecting the bandwidth impact on Tx power.

[0046] [ka] Regarding [ka] And, [ka] Regarding [ka] And in this case, K S This is provided by deltaMCS for each UL BWP b of each carrier f in serving cell c. It is a bit / resource element (BPRE) function that reflects the effect of the modulation and coding scheme (MCS) on the transmission power.

[0047] Referring to Figure 4A, this disclosure describes various embodiments of Method 400 for wireless communication. Method 400 may be implemented by a wireless communication device (e.g., user equipment). Method 400 may include a step 410 in which the user equipment (UE) reports a duration to a base station, the reported duration indicating to the base station at least one of an evaluation duration, a fallback duration, and an onset time, the fallback duration corresponding to an applied fallback power class, which is a transmission power lower than the declared or supported power class.

[0048] Referring to Figure 4B, Method 400 may further include some or all of the following steps: a UE determining whether the duty cycle during the evaluation duration is greater than the maximum duty cycle, and / or, in response to determining that the duty cycle during the evaluation duration is greater than the maximum duty cycle, a UE transmitting an uplink transmission having a fallback power class, the fallback power class having one of a reduced power class and a default power class.

[0049] In various embodiments of this disclosure, the duty cycle means the percentage of uplink symbols transmitted during a certain evaluation period.

[0050] In some implementations, the reported duration indicates to the base station the evaluation duration and the fallback duration, and / or the start time of the fallback duration is the first symbol of the next duration after the evaluation duration.

[0051] In some implementations, the reported duration indicates the fallback duration to the base station, and / or the start time of the fallback duration is reported either as the first symbol of the reported duration or by at least one of the radio frame index and slot index.

[0052] In some implementations, the UE sends a Power Headroom Report (PHR) to the base station, which includes a reported duration indicating the fallback duration.

[0053] In some implementations, the start time of the fallback duration is determined by the following: the PHR includes a start time of the fallback duration indicated by at least one of the radio frame index and slot index, and / or the start time of the fallback duration is determined by the time of the PHR, and / or in response to the PHR being retransmitted, the start time of the fallback duration is determined by one of the initial transmissions of the PHR.

[0054] In some implementations, the UE transmits a Power Headroom Report (PHR) to the base station, which includes a reported duration showing the total duration, including the evaluation duration and the fallback duration.

[0055] In some implementations, in response to subband full-duplex (SBFD) operation, the UE determines the duty cycle during the evaluation duration as a percentage of transmitted uplink symbols and transmitted uplink SBFD symbols, or of UL symbols transmitted during the evaluation period.

[0056] In some implementations, in response to SBFD operation, the UE determines the duty cycle during evaluation duration based on double-counting the SBFD symbols to calculate the total symbols within the subband.

[0057] In some implementations, in response to SBFD operation, the UE determines the duty cycle during the evaluation duration based on excluding SBFD symbols for duty cycles within subbands.

[0058] In some implementations, in response to SBFD operation within a subband, the UE determines the duty cycle during the evaluation duration based on counting all SBFD symbols as uplinks for the duty cycle within the subband.

[0059] In some implementations, in response to SBFD operation, the UE determines the duty cycle during evaluation duration based on treating the original band and subband as two separate bands by averaging the percentages of uplink symbols for the subband and the original band.

[0060] In some implementations, in response to SBFD operation in a subband, the UE determines the duty cycle during the evaluation duration based on treating the original band and subband as two separate bands by weight-averaging the percentages of uplink symbols of the subband with a first weight and the original band with a second weight, where the sum of the two weights is 1.

[0061] In some implementations, the first weight is the SBFD symbol divided by the sum of the SBFD symbol and all symbols, and the second weight is 1 minus the first weight, or the first weight is the SBFD symbol divided by all symbols, and the second weight is 1 minus the first weight.

[0062] In some implementations, in response to SBFD operation within a subband, the UE determines the duty cycle during the evaluation duration based on the first evaluation subduration of an SBFD symbol and the second evaluation subduration of other symbols by adding a first percentage of uplink SBFD symbols during the first evaluation subduration and a second percentage of other uplink symbols during the second evaluation subduration.

[0063] In some implementations, the method may further include averaging a first percentage of uplink SBFD symbols during a first evaluation subduration and a second percentage of other uplink symbols during a second evaluation subduration, or weighting a first percentage of uplink SBFD symbols during a first evaluation subduration and a second percentage of other uplink symbols during a second evaluation subduration.

[0064] In some implementations, in response to SBFD operation within a subband, the UE determines the duty cycle during the evaluation duration based on the evaluation duration of all symbols and the evaluation subduration of the SBFD symbols by adding a first percentage of uplink SBFD symbols during the evaluation subduration and a second percentage of other uplink symbols during the evaluation duration.

[0065] In some implementations, the method further includes averaging a first percentage of uplink SBFD symbols during the evaluation sub-duration and a second percentage of other uplink symbols during the evaluation duration, or weighting and averaging a first percentage of uplink SBFD symbols during the evaluation sub-duration and a second percentage of other uplink symbols during the evaluation duration.

[0066] In some implementations, SBFD symbols are either double-counted, excluded, or counted as all uplinks in the subband.

[0067] Embodiment Set I This disclosure describes various embodiments for determining statistical information and for describing power reduction or power recovery timelines. Various methods may include reporting / configuring one duration / period to determine at least one of the evaluation period and the duration for applying a reduction / default power class when the duty cycle is greater than a duty cycle threshold (e.g., maximum duty cycle). In some implementations, one duration / period is equal to the evaluation period and the duration for applying a reduction / default power class. In some implementations, one duration / period is only the duration for applying a reduction / default power class.

[0068] In some implementations, the current approach is to apply a "default power class" if the percentage of UL symbols is greater than the duty cycle, or to apply a "supported power class" if the percentage of UL symbols is not greater than the duty cycle. There are no restricted / defined timelines for applying reduced power or restoring supported power.

[0069] In some implementations, a power reduction or power recovery timeline is introduced to address the fact that the exact evaluation period and the duration of the applied reduction or default power class are not known in gNB.

[0070] In some implementations, if the duty cycle is greater than the maximum duty cycle (e.g., 50%), one duration / period is reported / configured to determine at least one of the evaluation period and the duration for applying the reduced / default power class.

[0071] In one method (Alternative Example 1), one duration / period is equal to the evaluation period and the duration for applying the reduced / default power class. The start time for applying the "reduced / default power class" is the first symbol of the next period if the duty cycle of the evaluation period is greater than the maximum duty cycle. In some implementations, the period value is a multiple of one radio frame, multiple radio frames, or two radio frames. For example, in the case of a multiple of two radio frames, the potential start time is the first symbol of the even frame, and the duration / period is two radio frames.

[0072] In an alternative method (Alternative Example 2), the single duration / period is solely the duration for which the reduced / default power class is applied. That is, regardless of the value of the evaluation period, the start time for applying the "reduced / default power class" is the first symbol within the period.

[0073] In some implementations, the duration value is two radio frames. For example, the potential start time is the first symbol of each even frame, regardless of whether the evaluation period is one or more radio frames.

[0074] In some implementations, when the evaluation period is defined / structured / reported, the start time may be the first symbol of the next evaluation period, which may be combined with an offset as needed, and the duration may be structured or a coefficient α × (evaluation period), i.e., α = 0.5, 1, 2, etc.

[0075] Various embodiments described herein may have the following advantages: they can configure or report at least one of the evaluation period and the duration for applying a reduced or default power class, and / or at least the duration for applying a reduced or default power class can be known by both the gNB and the UE. Therefore, it is beneficial to achieve more efficient utilization of the UE's maximum power in order to improve gNB scheduling decisions.

[0076] Embodiment Set II This disclosure describes various embodiments for determining statistical information and describes power headroom reporting (PHR) enhancements. In some implementations, various methods are used for fallback / default / reduced power class (PC) or ΔP PowerClass The report may only include reporting the duration to which the report was applied. In some implementations, various methods may only include reporting the total duration / period, including the evaluation period and the duration to which PC fallback was applied. ΔP may be included as needed. PowerClass It may also be reported at a smaller granularity, such as 1, 2, 3, or 4 dB. If necessary, PCs such as 20, 23, 26, or 29 dBm may also be reported.

[0077] In some implementations, at least one of the following is reported in conjunction with the PHR report: the evaluation period and the duration for applying the reduced / default power class, or the total duration including the evaluation period and the duration for applying the reduced / default power class. In other words, some additional information is reported to the gNB for more efficient power control.

[0078] In some implementations, the maximum permissible exposure (MPE) field may be used for frequency range 2 (FR2) and may be reused for frequency range 1 (FR1). Further considerations include using the MPE in FR2 as PC or ΔP PowerClass Alternatively, it can be reinterpreted as duration / period in FR1. For example, when reinterpreting MPE as PC, PC3, PC2, PC1.5, and PC1 can be considered as candidate values.

[0079] In some implementations, referring to Figure 5A, for the MPE field, if mpe-Reporting-FR2 is configured and the serving cell operates at FR2, and the P field is set to 1, this field indicates the power backoff applied to satisfy the MPE requirement. This field provides an index to Table 1 and may specify the corresponding measured value of the P-MPR level in dB. The field length is 2 bits. If mpe-Reporting-FR2 is not configured, or the serving cell operates at FR1, or the P field is set to 0, an R bit is present instead. Figure 5A shows a single-entry PHR medium access control (MAC) control element (CE).

[0080] The R field is a reserved bit and may be set to 0.

[0081] For the Power Headroom (PH) field, this field indicates the power headroom level. The field length is 6 bits. The reported PH and the corresponding power headroom level may be specified, and the corresponding measured value in dB may also be specified.

[0082] For the P field, if mpe-Reporting-FR2 is configured and the serving cell operates on FR2, the MAC entity shall set this field to 0 if the P-MPR value applied to satisfy the MPE requirement is less than the specified P-MPR_00, and to 1 otherwise. If mpe-Reporting-FR2 is not configured or the serving cell operates on FR1, this field indicates whether power backoff due to power management is applied (as permitted by P-MPRc as specified). If power backoff due to power management is not applied, the MAC entity shall set the corresponding P CMAX,f,c If the fields have different values, the P field shall be set to 1.

[0083] PCMAX,f,c In the case of a field, this field is used in the calculation of the preceding PH field. CMAX,f,c This shows the reported P CMAX,f,c The corresponding nominal UE transmission power level is specified, along with the corresponding measured value in dBm.

[0084] [Table 1]

[0085] Various embodiments may include other methods of enhancing PHR reporting, as will be discussed later.

[0086] One method (Method 1), as shown in Figure 5B, is the fallback / default / reduced power class or ΔP PowerClass The report only includes reporting the duration applied. If necessary, the duration is the same / fixed value. That is, after the duration, if the duty cycle is greater than the duty cycle threshold, it reverts to the declared power class and power class fallback. This approach has the following advantages: For different UE vendors, the evaluation period may differ, but ΔP PowerClass It may be provided that the duration applied to the report is known to both fixed / configured / reporting / gNB and UE, and / or that no restrictions are introduced to prevent triggering PC fallback. In some implementation forms, duration information may be added to the PHR MAC CE.

[0087] In some implementations, the start time of the duration may be determined by one of the following methods: In one method (Alternative Example 1), in addition to the duration being added to the PHR MAC CE, the start time is also added to the PHR MAC CE, for example, indicated by the index of the radio frame and, if necessary, by the index of the slot within the radio frame. In another method (Alternative Example 2), the start time is determined by when the MAC CE is received. In another method (Alternative Example 3), if the PUSCH carrying the MAC CE is received by retransmission, the start time is determined by the initial transmission of the PUSCH carrying the MAC CE.

[0088] Another method (method 2), referring to Figure 5C, involves reporting only the total duration / period, including the evaluation period and the duration for which PC fallback was applied. This method may have a trade-off: only the start of the evaluation and the end of the fallback PC may be known to the gNB, but the start of the duration for which PC fallback was applied may be variable. This method may offer the following advantage: at least a partial problem of the gNB not knowing the end of the applied PC fallback may be solved.

[0089] In some implementations, the start time of a period may be the first symbol of each period starting from wireless frame #0, or it may be determined in the same way as in Scheme 1.

[0090] The various embodiments described herein may have the following advantages, namely, that at least one of the evaluation period and the duration for applying a reduction or default power class may be configured or reported in combination with the PHR report, and / or at least the duration for applying a reduction or default power class may be known to both the gNB and the UE. To improve gNB scheduling decisions, it is beneficial to achieve more efficient utilization of the UE's maximum power.

[0091] Embodiment Set III This disclosure describes various embodiments for determining statistical information, and in the case of subbands introduced for subband full-duplex (SBFD) operation, it describes how to determine the duty cycle.

[0092] Various embodiments involve calculating the duty cycle based on a single band, regardless of DL / UL subbands. In some implementations, for a single band, the duty cycle is the percentage of transmitted uplink symbols and ULs compared to the percentage of transmitted SBFD symbols (percentage of transmitted UL symbols) during a given evaluation period, where the exact evaluation period is one or more radio frames. In some implementations, SBFD symbols within the same evaluation period may be double-counted for the duty cycle in the subband. In some implementations, SBFD symbols within the same evaluation period may not be counted for the duty cycle in the subband. In some implementations, SBFD symbols within the same evaluation period may be counted as 100% for the duty cycle calculation in the subband.

[0093] Various embodiments include calculating the duty cycle based on subband levels for duty cycle calculation. In some implementations, two (or three) subbands may be used to calculate the average percentage of uplink symbols and the average or weighted average percentage of uplink symbols for the UL subband and the original band.

[0094] Various embodiments involve calculating the duty cycle based on two evaluation periods. In some implementations, within the evaluation period (i.e., at least one radio frame), two sub-periods are divided: one is the duration of the subband time for SBFD symbol evaluation, and the other is for legacy UL symbol transmission evaluation.

[0095] In some implementations, the power class of a UE is related to the time-division duplex (TDD) duty cycle. If the duty cycle is changed by implementing SBFD, this may also affect the power class determination.

[0096] In some implementations, in addition to considering only the time domain, the two bands in band coupling (BC) may also be considered. Under some circumstances, only interband CA with two bands may be specified for the maximum output power of the UE.

[0097] In some implementations, the duty cycle may be determined as follows: For single-band, the duty cycle is the percentage of uplink symbols transmitted during an evaluation period (the exact evaluation period is one or more radio frames). For inter-band CA (two bands) or SUL, the duty cycle is 50% × (Duty NR,x / maxDuty NR,x +Duty NR,y / maxDuty NR,y This is the average percentage of uplink symbols defined as Duty. NR,x Duty NR,y This represents the actual percentage of uplink symbols transmitted during the same evaluation period, where the exact evaluation period is at least one radio frame for NR band x and NR band y, respectively. maxDuty NR,x maxDuty NR,y This represents the UE capability field maxUplinkDutyCycle-PC2-FR1 for each band.

[0098] Various embodiments include various methods for determining the duty cycle in the case of subbands introduced for SBFD operation.

[0099] For one method (Method 1), various approaches include calculating the duty cycle based on a single band, regardless of the DL / UL subband, by one of the following methods:

[0100] In one method (Alternative Example 1), for single-band applications, referring to Figure 6A, the duty cycle is the percentage of transmitted uplink symbols and ULs of transmitted SBFD symbols during an evaluation period, where the exact evaluation period is one or more radio frames. In other words, for single-band applications, the duty cycle is the percentage of transmitted UL symbols during an evaluation period. As a non-restrictive example, in Figure 6A, one radio frame may contain 10 slots, each slot may contain 14 symbols, the subcarrier spacing (SCS) may be 15 kHz, and the duty cycle is calculated as Duty Cycle = (2 + 28) / 140 = 21.43%.

[0101] In another non-restrictive example, in Figure 6B, the duty cycle is calculated as Duty Cycle = (14 + 2 + 28) / 140 = 0.1 + 0.2143 = 31.43%.

[0102] In some implementations, the same SBFD symbol may also have a downlink transmission, which may not align with the intended duty cycle; that is, both the DL signal and the UL signal may be present at the same time.

[0103] Alternatively (Alternative Example 2), SBFD symbols within the same evaluation period may be double-counted for duty cycles within the subband. In other words, one SBFD symbol may be considered "two symbols" in evaluation, especially for UEs capable of receiving and transmitting simultaneously, as "three symbols" in a "DUD" structure if necessary. In a non-restrictive example, in Figure 6B, the duty cycle is calculated as Duty Cycle = 14 / (56+140)+(2+28) / 140 = 0.0714+0.2143 = 28.57%.

[0104] In an alternative method (Alternative Example 3), SBFD symbols within the same evaluation period may not be counted for duty cycles within the subband. In other words, a single SBFD symbol may be discarded in evaluation, especially for UEs capable of receiving and transmitting simultaneously. In a non-restrictive example, in Figure 6B, the duty cycle is calculated as Duty Cycle = (2 + 28) / 140 = 21.43%.

[0105] Alternatively (Alternative Example 4), SBFD symbols within the same evaluation period may be counted as 100% for duty calculations within the subband. In other words, one SBFD symbol may be considered an "FDD" band for evaluation purposes, especially for UEs that have the ability to receive and transmit simultaneously. In a non-restrictive example, in Figure 6B, the duty cycle is calculated as Duty Cycle = (56 / 140)*100% + (2+28) / 140 = 0.4 + 0.2143 = 61.43%.

[0106] In another method (Method 2), various methods involve calculating the duty cycle based on subband levels for duty cycle calculation. Two (or three) subbands may be used to calculate the average percentage of uplink symbols.

[0107] For one sub-method (method 2-1), the duty cycle may be calculated based on the average percentage of uplink symbols of the UL subband and the original band.

[0108] In one method (alternative example 1), the duty cycle is 50% × (Duty NR,x_subband / maxDuty NR,x_subband +Duty NR,x / maxDuty NR,x, ) may be calculated as, where Duty NR,x Duty NR,x_subbandThis represents the actual percentage of uplink symbols and ULs transmitted for SBFD symbols during the same evaluation period, where the exact evaluation period is at least one radio frame for NR band x and subbands within NR band x. maxDuty NR,x_subband maxDuty NR,x This represents the UE capability per band maxUplinkDutyCycle-PC2-FR1 field, and in some implementations, maxDuty NR,x_subband maxDuty NR,x It is equal to. In some other implementations, maxDuty NR,x_subband These can be configured independently. As a non-restrictive example, in Figure 6B, maxDuty NR,x_subband =maxDuty NR,x = 50%. The duty cycle is calculated as Duty Cycle = 50% × (10% / 50% + 21.43% / 50%) = 31.43%.

[0109] In another method (alternative example 2), the duty cycle is 50% × (Duty NR,x_subband / maxDuty NR,x_subband +Duty NR,x / maxDuty NR,x, ) may be calculated as Duty NR,x Duty NR,x_subband This represents the actual percentage of uplink symbols and ULs transmitted SBFD symbols during the same evaluation period, where the exact evaluation period is at least one radio frame for NR band x and subbands within NR band x. Furthermore, SBFD symbols within the same evaluation period are subject to Duty NR,x_subband It may be double-counted for maxDuty NR,x_subband maxDuty NR,x This represents the UE capability per band, maxUplinkDutyCycle-PC2-FR1 field. In some implementations, maxDuty NR,x_subband maxDuty NR,x It is equal to. In some other implementations, maxDuty NR,x_subbandThese may be configured independently. As a non-limiting example, in Figure 6B, maxDuty NR,x_subband =maxDuty NR,x = 50%. The duty cycle is calculated as Duty Cycle = 50% × (7.14% / 50% + 21.43% / 50%) = 28.57%.

[0110] In another sub-method (method 2-2), the duty cycle may be calculated based on the weighted average percentage of the uplink symbols of the UL subband and the original band, according to the various methods described below. The motivation is that the UL subband lies on a partial slot / symbol rather than the entire carrier in the time domain. If necessary, the UL subband lies on a partial PRB of the BWP / carrier rather than the entire BWP / carrier in the frequency domain.

[0111] In one method (alternative example 1), the duty cycle is P1 × Duty NR,x_subband / maxDuty NR,x_subband +P2×Duty NR,x / maxDuty NR,x Duty NR,x Duty NR,x_subband P1 represents the actual percentage of transmitted uplink symbols and ULs of transmitted SBFD symbols during the same evaluation period, where the exact evaluation period is at least one radio frame for NR band x and subbands within NR band x. P1 is the first weight of the weighted average, the number of (SBFD symbols) / (SBFD symbols + all symbols) during the evaluation period, P2 is the second weight of the weighted average, the number of (all symbols) / (SBFD symbols + all symbols) during the evaluation period, and maxDuty NR,x_subband maxDuty NR,x This represents the UE capability per band maxUplinkDutyCycle-PC2-FR1 field, and maxDuty NR,x_subband maxDuty NR,x It is equivalent to . In some implementations, maxDuty NR,x_subbandcan be configured independently. As a non-limiting example, in FIG. 6B, maxDuty NR,x_subband = maxDuty NR,x = 50%. The duty cycle is calculated as Duty Cycle = 4 / 14×(10% / 50%) + 10 / 14×21.43% / 50% = 0.0571 + 0.3061 = 36.32%.

[0112] In another way (Alternative Example 2), the duty cycle may be calculated as P1×Duty NR,x_subband / maxDuty NR,x_subband + P2×Duty NR,x / maxDuty NR,x Duty NR,x and Duty NR,x_subband represent the actual percentages of transmitted uplink symbols and SBFD symbols where UL was transmitted in the same evaluation period. The exact evaluation period is 1 radio frame or more for NR band x and each sub-band within NR band x. In some implementations, P1 is the first weight of the weighted average and is the number of (SBFD symbols) / (all symbols) within the evaluation period. In some implementations, P2 is the second weight of the weighted average and P2 = 1 - P1 or is the number of (non-SBFD symbols) / (all symbols) within the evaluation period. maxDuty NR,x_subband and maxDuty NR,x represent the field of UE capability maxUplinkDutyCycle-PC2-FR1 per band, and maxDuty NR,x_subband is equal to maxDuty NR,x In some implementations, maxDuty NR,x_subband can be configured independently. In some implementations, P1 / P2 can be determined by the percentage of the frequency of the UL sub-band and the original frequency of the BWP / carrier / band. For example, P1 = (PRB of the sub-band) / (PRB of the UL carrier) and P2 = 1 - P1. As a non-limiting example, in FIG. 6B, maxDuty NR,x_subband = maxDuty NR,x= 50%. The duty cycle is calculated as Duty Cycle = 4 / 10 × (10% / 50%) + 6 / 10 × 21.43% / 50% = 0.08 + 0.25716 = 33.72%.

[0113] Alternatively (Alternative Example 3), P1 and P2 can be determined by the frequency of the UL subband and the percentage of the original frequency of the BWP / carrier / band. For example, P1 = (PRB of the subband) / (PRB of the UL carrier) and P2 = 1 - P1.

[0114] Alternatively (Alternative Example 4), P1 and P2 can be determined by the frequency of the UL subband and the percentage of the original frequency of the BWP / carrier / band. For example, P1 = (PRB of subband) / (PRB of subband + PRB of UL carrier) and P2 = 1 - P1.

[0115] In another method (alternative example 5), the duty cycle is P1 × Duty NR,x_subband / maxDuty NR,x_subband +P2×Duty NR,x / maxDuty NR,x Duty NR,x Duty NR,x_subband This represents the actual percentage of uplink symbols and ULs transmitted SBFD symbols during the same evaluation period, where the exact evaluation period is at least one radio frame for NR band x and subbands within NR band x. Furthermore, SBFD symbols within the same evaluation period are subject to Duty NR,x_subband Double counting may be permitted for this. If necessary, P1 and P2 can be determined by other means, any of the methods in the alternative examples above. For example, based on Alternative Example 1, P1 is the first weight of the weighted average, the number of (SBFD symbols) / (SBFD symbols + all symbols) during the evaluation period, and P2 is the second weight of the weighted average, the number of (all symbols) / (SBFD symbols + all symbols) during the evaluation period, and maxDuty NR,x_subband maxDutyNR,x This represents the UE capability per band maxUplinkDutyCycle-PC2-FR1 field, and maxDuty NR,x_subband maxDuty NR,x It is equivalent to . In some implementations, maxDuty NR,x_subband These can be configured independently. In some implementations, P1 / P2 can be determined by the frequency of the UL subband and the percentage of the original frequency of the BWP / carrier / band. In a non-restrictive example, in Figure 6B, maxDuty NR,x_subband =maxDuty NR,x When = 50%, the duty cycle is calculated as Duty Cycle = 4 / 14 × (7.14% / 50%) + 10 / 14 × (21.43% / 50%) = 0.0408 + 0.3061 = 34.69%.

[0116] In another method (Method 3), the duty cycle may be calculated based on two evaluation periods according to the various methods described below.

[0117] In one method (Alternative Example 1), within the evaluation period (i.e., at least one radio frame), two sub-periods are divided: one is the duration of the subband time for SBFD symbol evaluation, and the other is for legacy UL symbol transmission evaluation. Detailed percentages can be based on addition without averaging (or addition without averaging), equal averages, or weighted averages.

[0118] In a non-restrictive example based on addition, in Figure 6B, the duty cycle is calculated as Duty Cycle = (14 / (14×4)) + ((2+28) / (14×6)) = 0.25 + 0.3571 = 60.71%.

[0119] In another non-restrictive example based on the mean (or equal mean), in Figure 6B, the duty cycle is calculated as Duty Cycle = 50% × (14 / (14 × 4)) + 50% × ((2 + 28) / (14 × 6)) = 50% × (0.25 + 0.3571) = 30.35%.

[0120] In another non-restrictive example based on a weighted average, in Figure 6B, the duty cycle is calculated as 4 / 10 × (14 / (14 × 4)) + 6 / 10 × ((2 + 28) / (14 × 6)) = 0.1 + 0.2143 = 31.43%.

[0121] In some implementations, SBFD symbols during the evaluation period are Duty NR,x_subband Double counting may be permitted for this. In an unrestricted example based on addition, in Figure 6B, the duty cycle is calculated as (14 / (14×4×2))+((2+28) / (14×6))=0.125+0.3571=48.21%. In another unrestricted example based on mean (or equal mean), in Figure 6B, the duty cycle is calculated as 50%×(14 / (14×4×2))+50%×((2+28) / (14×6))=50%×(0.125+0.3571)=24.11%. In another non-restrictive example based on a weighted average, in Figure 6B, the duty cycle is calculated as 4 / 10 × (14 / (14 × 4 × 2)) + 6 / 10 × ((2 + 28) / (14 × 6)) = 0.05 + 0.2143 = 26.43%.

[0122] In an alternative method (Alternative Example 2), an additional sub-period for SBFD symbol evaluation is derived within the evaluation period (i.e., at least one wireless frame). In some implementations, the detailed percentage may be based on adding with or without averaging. In an unrestricted example based on adding without averaging, in Figure 6B, the duty cycle is calculated as (14 / (14×4))+((2+28) / (14×10))=0.25+0.2143=46.43%. In another unrestricted example based on weighted averaging, in Figure 6B, the duty cycle is calculated as 4 / 10×(14 / (14×4))+((2+28) / (14×10))=0.1+0.2143=31.43%.

[0123] In some implementations, SBFD symbols during the evaluation period are Duty NR,x_subband Double counting may be permitted for this. In an unrestricted example based on addition without averaging, in Figure 6B, the duty cycle is calculated as (14 / (14×4×2))+((2+28) / (14×10))=0.125+0.2143=33.93%. In another unrestricted example based on weighted averaging, in Figure 6B, the duty cycle is calculated as 4 / 10×(14 / (14×4×2))+((2+28) / (14×10))=0.05+0.2143=26.43%.

[0124] In some implementations, the three methods described above may include: Method 1, where SBFD symbol processing is optimized based on a single band in which UL is transmitted with arbitrary symbols; Method 2, where SBFD symbol processing is optimized based on "two bands" in which the UL subband and the original band are considered as two bands by averaging, weight averaging is optimized, and SBFD symbol processing is optimized; and Method 3, where SBFD symbol processing is optimized based on a single band having two periods in which one is an evaluation period having two non-overlapping sub-periods and the other is an evaluation period having another sub-period, weight averaging is optimized.

[0125] The various embodiments described herein may have the following advantages, namely, different methods for calculating the duty cycle of the introduced SBFD, and / or the exact duty cycle, which can be derived for carrier-supported SBFDs in which the UL subband is comprised of several downlink symbols. To improve gNB scheduling decisions when an SBFD is introduced, it is beneficial to achieve more efficient utilization of the UE's maximum power.

[0126] Embodiment Set IV This disclosure describes various embodiments for determining statistical information and includes a hypothetical PHR report.

[0127] In some implementations, if the UE determines that the Type 1 power headroom report of an activated serving cell is based on a reference push transmission (virtual PHR report) for the push transmission opportunity i in the active UL BWP b of the carrier f of serving cell c, the UE will then perform the Type 1 power headroom report. [ka] Calculated as follows, here, [ka] Here, MPR=0dB, A-MPR=0dB, P-MPR=0dB. ΔT C Calculations are performed assuming =0dB. MPR, A-MPR, P-MPR, ΔT C This is defined. The remaining parameters are defined, and if ul-powerControl is not provided, [ka] teeth, [ka] And obtained using p0-PUSCH-AlphaSetId=0, PL b,f,c (q d) is obtained using push-PathlossReferenceRS-Id=0 and l=0. If ul-powerControl is provided, [ka] This is obtained by the p0-Alpha-CLID-PUSCH-Set associated with the indicated TCI-State or TCI-UL-State, PL b,f,c (q d ) is obtained by the PL-RS associated with the indicated TCI-State or TCI-UL-State.

[0128] Here, Type 1 power headroom is the difference between the nominal UE maximum transmission power and the estimated power for UL-SCH transmission per activated serving cell.

[0129] A single-entry PHR MAC CE has a fixed size and consists of two octets as defined in Figure 5A. Referring to Figure 7A, a multi-entry PHR MAC CE has a variable size and consists of a bitmap and associated P of the Sp cells of other MAC entities. CMAX,f,c Type 2PH fields and octets including the field (if reported), and associated P cells. CMAX,f,c Includes a Type 1PH field and octet, including the field (if reported). This is further sorted in ascending order based on ServCellIndex, and includes associated P for serving cells other than the P cells shown in the bitmap. CMAX,f,c Type X PH contains one or more fields and octets, including a field (if reported). X is either 1 or 3. Figure 7A shows a multi-entry PHR MAC CE where the maximum ServCellIndex of serving cells with configured uplinks is less than 8. Figure 7B shows an extended single-entry PHR for a multi-TRP MAC CE.

[0130] In some implementations, the PHR has 64 power headroom levels, and the power headroom reporting range is -32 to +38 dB. Table 2 defines the reporting mapping. [Table 2]

[0131] In some implementations, for virtual PHR reporting, and for 1RB-based PUSCH, [ka] This is a very small value that can result in a virtual PHR greater than 38 dB. For example, if P0=100 dBm, Pathloss=80 dB, Pcmax=17 dBm, fi=0, and alpha=0.8, the result is PHR=17-(-100+0.8*80)=53 dB. This may result in POWER_HEADROOM_63 being reported and the exact value of PHR being unknown by gNB. This may further affect UL power control as well as UL adaptive modulation and coding.

[0132] To solve this problem, various embodiments include introducing higher or lower levels of power headroom.

[0133] One method (Method 1) introduces more levels. For example, a 7-bit power headroom report mapping table is defined as shown in Table 3 below. [Table 3]

[0134] In another method (Method 2), the entries in the power headroom report mapping table remain unchanged, but several new levels are introduced. For example, a 6-bit power headroom report mapping table is defined as Table 4. [Table 4]

[0135] In another method (Method 3), a separate table (Table 5) with new PH levels is introduced. For example, the second 6-bit power headroom report mapping table is defined as follows. The PHR MAC CE can be used similarly to the extended PHR MAC CE, in which case it includes two or more PH fields for the serving cell. For example, PH1 is based on the legacy 6-bit power headroom report mapping table, and PH2 is based on the second 6-bit power headroom report mapping table. [Table 5]
