Abstract
Description
Technical Field
[0001] This application relates to the field of communication systems, and in particular, to a wireless communication method and a user equipment (UE). Background Art
[0002] Multiple-input and multiple output (MIMO) is an effective method to improve the capacity of wireless links through the reuse of transmit and receive antennas. MIMO refers to a practical technology that can simultaneously transmit and receive multiple data signals on the same wireless channel, thereby significantly improving the performance of spectral efficiency.
[0003] In Rel-15 / 16 / 17, although the UE has one or more panels, when performing uplink (UL) transmission on the carrier of a serving cell, only one panel is allowed to transmit. Therefore, for uplink transmission, the UE is configured with an output maximum power value, and only needs to calculate the scheduled power according to scheduling parameters (such as target power, number of physical resource blocks (PRBs), path loss, path loss compensation factor, power offset, closed-loop power control, etc.). When the scheduled power is not greater than the output maximum power, the UE uses the scheduled power for uplink transmission; when the scheduled power is greater than or equal to the output maximum power, the UE uses the output maximum power for uplink transmission. In the Work Item Description (WID) of Rel-18, a new content is introduced, that is, multiple panels in the UE can simultaneously perform multiple uplink transmissions. In the recent three meetings, various transmission modes (system frame number (SFN), frequency-division multiplexing (FDM), subscriber data management (SDM) scheme for the physical uplink shared channel (PUSCH) + PUSCH and SFN, FDM scheme for the physical uplink control channel (PUCCH) + PUCCH) and the degree of overlap (complete overlap, partial overlap) have been reached a consensus. This means that different panels need to be independently controlled. Therefore, it is necessary to enhance the power control mechanism for multi-panel UEs.

[0038] This application aims to solve the problem that the multi-panel UE power control mechanism is not clearly defined in the prior art.
[0039] Please refer to Figure 2 . Figure 2 is a schematic diagram showing a user equipment (UE) 20, which includes multiple panels 200 and 202, and multiple base stations (BS) 22 and 24.
[0040] MIMO technology is one of the key technologies in the new radio access (NR) system and has been successfully commercially deployed. In the MIMO communication system as Figure 2 shown, both the UE 20 and the base stations 22 and 24 include a large number of antenna units. It should be noted that the base station 22 or 24 may be (but is not limited to) a gNB or a network (NW). Especially for the UE 20, these antenna units may be distributed in different panels (i.e., Figure 2 the panels 200 and 202 shown). The panels 200 and 202 are installed in different positions so that the UE 20 can better communicate with the base stations 22 and 24. That is to say, the UE 20 can be regarded as a multi-panel UE. It should be pointed out that although Figure 2 the UE in includes two panels 200 and 202, the UE 20 may also include three or more panels.
[0041] Please refer toFigure 3 。 Figure 3 This is a schematic diagram showing a wireless communication method that can be executed in a UE according to an embodiment of the present application. In this embodiment, the UE includes multiple panels, and the UE can perform multiple uplink (UL) transmissions simultaneously. Specifically, each panel of the UE can simultaneously transmit multiple uplink signals / channels. Therefore, the UE needs to calculate the scheduling power values corresponding to each panel respectively. The scheduling power value is the power value of the uplink channel or signal (channel / signal) corresponding to a certain panel, but it is not the actual transmission power value. The scheduling power value is calculated according to the scheduling parameters of the uplink channel / signal, such as target power, physical resource block (PRB) quantity, path loss, path loss compensation factor, power offset, closed-loop power control, etc. The wireless communication method includes the following operation steps:
[0042] In operation S300, the UE is configured to have at least one of a first output maximum power value and a second output maximum power value of each panel. The first output maximum power value is the output maximum power value configured by the UE and is configured by the base station. The second output maximum power value of each panel is the output maximum power value configured by the panel and is also configured by the base station.
[0043] Specifically, the UE can be configured to have the first output maximum power value; or, the UE can be configured to have the second output maximum power value of each panel; or, the UE can be configured to have both the first output maximum power value and the second output maximum power value of each panel simultaneously.
[0044] In operation S302, the UE calculates the scheduling power value of each panel. The scheduling power value of each panel is the power value of the uplink channel or signal (channel / signal) corresponding to that panel.
[0045] As described above, the UE calculates the scheduling power value of each panel according to the scheduling parameters of the uplink channel / signal, and these scheduling parameters include target power, physical resource block (PRB) quantity, path loss, path loss compensation factor, power offset, closed-loop power control, etc.
[0046] In operation S304, the UE determines the UL transmission power value of the UE or each panel.
[0047] Please refer to Figure 4 。 Figure 4 This is a schematic diagram showing, according to an embodiment of the present application, Figure 3 the specific operation process of operation S304 in. In this embodiment, the UE is configured to have the second output maximum power value of each panel. Figure 3The operation S304 includes the following specific operation steps.
[0048] In operation S3040, the UE determines whether the scheduling power value of each panel is less than or equal to the second maximum output power value of that panel.
[0049] In operation S3042, the UE determines the UL transmission power value of each panel according to the judgment result of operation S3040.
[0050] Please refer to Figure 5 . Figure 5 is a schematic diagram showing, according to an embodiment of the present application, Figure 4 the specific operation process of operation S3042 in
[0051] In operation S30420, when the UE determines that the scheduling power value of each panel is less than or equal to the second maximum output power value of that panel, the UE determines the scheduling power value of that panel as the uplink transmission power value of that panel.
[0052] In operation S30422, when the UE determines that the scheduling power value of each panel is not less than or not equal to the second maximum output power value of that panel, the UE determines the second maximum output power value of that panel as the uplink transmission power value of that panel.
[0053] In summary, when the scheduling power value of a certain panel is less than or equal to the second maximum output power value of that panel, that panel uses its scheduling power value for UL transmission. When the scheduling power value of a certain panel is not less than or not equal to the second maximum output power value of that panel, that panel uses its second maximum output power value for uplink transmission.
[0054] For example, assume that a certain UE includes a first panel and a second panel. The UE is configured such that the second maximum output power value of the first panel is P cmax,panel1 , and the second maximum output power value of the second panel is P cmax,panel2 . The UE calculates the scheduling power value P scheduling,panel1 of the first panel and the scheduling power value P scheduling,panel2 of the second panel. Assume that the first maximum panel power P cmax,UE＝Pcmax,panel1+Pcmax,panel2 configured for the UE. When the scheduling power value P scheduling,panel1 of the first panel is less than or equal to (<=) its corresponding second maximum output power value P cmax,panel1 , the first panel of the UE will use this scheduling power value P scheduling,panel1 as the actual transmission power value for uplink transmission. When the scheduling power value P scheduling,panel1 of the first panel is greater than (>) its second maximum output power value P cmax,panel1 , the first panel of the UE will use this second maximum output power value Pcmax,panel1 For uplink transmission, the actual transmission power value is used. The behavior of the second panel is the same as that of the first panel.
[0055] Please refer to Figure 6 . Figure 6 is a schematic diagram showing, according to another embodiment of the present application, Figure 3 the specific operation process of operation S304 in. In this embodiment, the UE is configured with a first maximum output power value, and the second maximum output power value of each panel is equal to the first maximum output power value divided by the number of panels. Operation S304 includes the following operation steps:
[0056] In operation S3050, the UE determines whether the scheduled power value of each panel is less than or equal to the second maximum output power value of that panel.
[0057] In operation S3052, the UE determines the UL transmission power value of each panel according to the above judgment result.
[0058] Please refer to Figure 7 . Figure 7 is a schematic diagram showing, according to an embodiment of the present application, Figure 6 the specific operation process of operation S3052 in.
[0059] In operation S30520, when the scheduled power value of each panel is less than or equal to the second maximum output power value of that panel, the UE determines the scheduled power value of that panel as the UL transmission power value of that panel.
[0060] In operation S30522, when the scheduled power value of each panel is not less than or not equal to the second maximum output power value of that panel, the UE determines the second maximum output power value of that panel as the uplink transmission power value of that panel.
[0061] In summary, when the scheduled power value of a certain panel is less than or equal to the second maximum output power value of that panel (i.e., the first maximum output power value divided by the number of panels), that panel uses its scheduled power value for uplink transmission; when the scheduled power value of a certain panel is not less than or not equal to the first maximum output power value of that panel (i.e., the first maximum output power value divided by the number of panels), that panel uses its second maximum output power value (i.e., the first maximum output power value divided by the number of panels) for uplink transmission.
[0062] For example, assume that a certain UE includes a first panel and a second panel. The UE is configured with a first maximum output power value P cmax,UE . The UE calculates the scheduled power value P scheduling,panel1 of the first panel and the scheduled power value P scheduling,panel2 of the second panel. The second maximum output power value Pcmax,panel1 and the second output maximum power value P of the second panel cmax,panel2 are both equal to half of the first output maximum power value P cmax,UE . When the scheduling power value P of the first panel scheduling,panel1 is less than or equal to (<=) its second output maximum power value P cmax,panel1 (i.e., half of the first output maximum power value), the first panel of the UE uses this scheduling power value P scheduling,panel1 as the actual transmission power value for uplink transmission. When the scheduling power value P of the first panel scheduling,panel1 is not less than or not equal to (>) its second output maximum power value P cmax,panel1 (i.e., half of the first output maximum power value), the first panel of the UE uses this second output maximum power value P cmax,panel1 (i.e., half of the first output maximum power value) as the actual transmission power value for uplink transmission. The behavior of the second panel is the same as that of the first panel.
[0063] Please refer to Figure 8 . Figure 8 is a schematic diagram showing, according to another embodiment of the present application, Figure 3 the specific operation process of operation S304. In this embodiment, the UE is configured to have a first output maximum power value, and the second output maximum power value of each panel is equal to this first output maximum power value. Figure 3 The operation S304 in
[0064] includes the following operation steps:
[0065] In operation S3060, the UE determines whether the sum of the scheduling power values of each panel is less than or equal to the first output maximum power value.
[0066] Please refer to Figure 9 . Figure 9 is a schematic diagram showing, according to an embodiment of the present application, Figure 8 the specific operation process of operation S3062.
[0067] In operation S30620, when the sum of the scheduling power values of each panel is less than or equal to the first output maximum power value, the UE determines the scheduling power value as the uplink transmission power value of each panel.
[0068] In operation S30622, when the sum of the scheduling power values of each panel is not less than or not equal to the first output maximum power value, the UE determines the UL transmission power value of each panel according to at least one parameter. The at least one parameter includes at least one of the following information: the priority of the uplink transmission of each panel, the power magnitude of the uplink transmission of each panel, and the time arrangement of the uplink transmission of each panel.
[0069] In summary, when the sum of the scheduling power values of all panels is less than or equal to the first output maximum power value, each panel uses its scheduling power value for uplink transmission. For example, assume a UE includes a first panel and a second panel. The UE is configured with a first output maximum power value P cmax,UE . The UE calculates the scheduling power value P scheduling,panel1 of the first panel and the scheduling power value P scheduling,panel2 of the second panel. The second output maximum power value P cmax,panel1 of the first panel and the second output maximum power value P cmax,panel2 of the second panel are both configured to be equal to the first output maximum power value P cmax,UE . When the sum of the first scheduling power value P scheduling,panel1 and the second scheduling power value P scheduling,panel2 is less than or equal to the first output maximum power value P cmax,UE , the first panel of the UE uses the scheduling power value P scheduling,panel1 as the actual transmission power value for uplink transmission, and the second panel uses the scheduling power value P scheduling,panel2 as the actual transmission power value for uplink transmission.
[0070] When the sum of the scheduling power values of all panels is not less than or not equal to the first output maximum power value, the UE further determines the UL transmission power value of each panel according to at least one of the following information: the priority of the uplink transmission of each panel, the power magnitude of the uplink transmission of each panel, and the time arrangement of the uplink transmission of each panel. That is to say, the UE will determine the power allocation order of each panel. Subsequently, after the order is determined, the corresponding uplink transmission power value is allocated to each panel.
[0071] In an embodiment of the present application, the UE determines the power allocation order of the panels according to the priorities of the uplink transmissions of the respective panels. The UE will first allocate an appropriate power value to the first panel for high-priority uplink transmission, and allocate the remaining power value to the second panel for low-priority uplink transmission. This can ensure the channel quality of high-priority uplink transmission. For example, the first panel and the second panel of the UE simultaneously send a first PUSCH with a hybrid automatic repeat request (HARQ) and a second PUSCH carrying only data, respectively. Since the priority of HARQ is higher than that of ordinary data, the first panel of the UE will use its scheduled power value P scheduling,panel1 as the actual transmission power value to send the first PUSCH with data multiplexing of HARQ; the second panel of the UE will use the remaining power value (P cmax,UE -P scheduling,panel1 ) as the actual transmission power value to send the second PUSCH containing only data. It should be noted that P cmax,UE -P scheduling,panel1 is less than P scheduling,panel2 . On the contrary, the UE can also first allocate an appropriate power value to the second panel for low-priority uplink transmission, and then allocate the remaining power to the first panel for high-priority uplink transmission.
[0072] In another embodiment of the present application, the UE determines the power allocation order according to the magnitudes of the uplink transmission powers of the respective panels. The UE will first allocate an appropriate power value to the first panel with a larger scheduled power, and allocate the remaining power value to the second panel with a smaller scheduled power. This can ensure the channel quality of the uplink transmission with a larger scheduled power. For example, the first panel and the second panel of the UE simultaneously send a first PUSCH and a second PUSCH, respectively. When the scheduled power value P scheduling,panel1 of the first panel is greater than the scheduled power value P scheduling,panel2 of the second panel, the first panel of the UE will use its scheduled power value P scheduling,panel1 as the actual transmission power value to send the first PUSCH, while the second panel will use the remaining power value (P cmax,UE -P scheduling,panel1 ) as the actual transmission power value to send the second PUSCH. It should be noted that P cmax,UE -P scheduling,panel1 is less than P scheduling,panel2 . On the contrary, the UE can also first allocate an appropriate power value to the second panel with a smaller scheduled power, and then allocate the remaining power to the first panel with a larger scheduled power.
[0073] In another embodiment of the present application, the UE determines the power allocation order according to the transmission time order of the uplink transmissions of each panel. The UE will first allocate an appropriate power value to the first panel with an earlier transmission timing, and allocate the remaining power to the second panel with a later transmission timing. This can ensure the channel quality of the uplink transmission with an earlier transmission timing. For example, the first panel and the second panel respectively and simultaneously send the first PUSCH and the second PUSCH. When the transmission time of the first PUSCH is earlier than that of the second PUSCH, the first panel of the UE uses its scheduled power value P scheduling,panel1 as the actual transmission power value to send the first PUSCH, while the second panel uses the remaining power value (P cmax,UE -P scheduling,panel1 ) as the actual transmission power value to send the second PUSCH. It should be noted that P cmax,UE -P scheduling,panel1 is less than P scheduling,panel2 . On the contrary, the UE can also first allocate an appropriate power value to the second panel with a later transmission timing, and then allocate the remaining power to the first panel with an earlier transmission timing.
[0074] In another embodiment of the present application, the UE determines the power allocation order according to the priority and power magnitude of the uplink transmissions of each panel. The UE will first allocate an appropriate power to the first panel performing the high-priority uplink transmission, and allocate the remaining power to the second panel performing the low-priority uplink transmission. When the first uplink transmission and the second uplink transmission have the same priority, the UE further determines the power allocation order according to the power magnitude of the uplink transmissions of each panel. The UE will allocate an appropriate power to the first panel with a larger scheduled power, and allocate the remaining power to the second panel with a smaller scheduled power.
[0075] For example, the first panel and the second panel respectively and simultaneously send the first uplink transmission and the second uplink transmission. When the first uplink transmission has a higher priority, the first panel of the UE uses its scheduled power value P scheduling,panel1 as the actual transmission power value to send the first transmission, while the second panel uses the remaining power value (P cmax,UE -P scheduling,panel1 ) as the actual transmission power value to send the second transmission. When the second uplink transmission has a higher priority, the second panel of the UE uses its scheduled power value P scheduling,panel2 as the actual transmission power value to send the second transmission, while the first panel uses the remaining power value (P cmax,UE -P scheduling,panel2)Send the first transmission as the actual transmission power value. When the first transmission and the second transmission have the same priority, the UE further determines the power allocation order according to the power magnitudes of the uplink transmissions of each panel: When the first uplink transmission has a larger power value, the first panel uses its scheduled power value P scheduling,panel1 to send the first transmission as the actual transmission power value, while the second panel uses the remaining power value (P cmax,UE - P scheduling,panel1 ) to send the second transmission as the actual transmission power value; When the second uplink transmission has a larger power value, the second panel uses its scheduled power value P scheduling,panel2 to send the second transmission as the actual transmission power value, while the first panel uses the remaining power value (P cmax,UE - P scheduling,panel2 ) to send the first transmission as the actual transmission power value. In another embodiment, the UE can also first determine the power allocation order according to the power magnitudes of the uplink transmissions of each panel; When the power magnitudes are the same, further determine the power allocation order according to the priorities of the uplink transmissions of each panel.
[0076] In yet another embodiment of the present application, the UE determines the power allocation order according to the priorities and transmission timings of the uplink transmissions of each panel. The UE will preferentially allocate appropriate power to the first panel performing the high-priority uplink transmission and allocate the remaining power to the second panel performing the low-priority uplink transmission. When the first uplink transmission and the second uplink transmission have the same priority, the UE further determines the power allocation order according to the transmission timings of the uplink transmissions of each panel. The UE will allocate appropriate power to the first panel with an earlier transmission timing and allocate the remaining power to the second panel with a later transmission timing. In another embodiment, the UE can also first determine the power allocation order according to the transmission timings of the uplink transmissions of each panel; When the transmission timings are the same, further determine the power allocation order according to the priorities of the uplink transmissions of each panel.
[0077] In yet another embodiment of the present application, the UE determines the power allocation order according to the power magnitudes and transmission timings of the uplink transmissions of each panel. The UE will preferentially allocate appropriate power to the first panel with a larger scheduled power and allocate the remaining power to the second panel with a smaller scheduled power. When the power magnitudes of the first uplink transmission and the second uplink transmission are the same, the UE further determines the power allocation order according to the transmission timings of the uplink transmissions of each panel. The UE will allocate appropriate power to the first panel with an earlier transmission timing and allocate the remaining power to the second panel with a later transmission timing. In another embodiment, the UE can also first determine the power allocation order according to the transmission timings of the uplink transmissions of each panel; When the transmission timings are the same, further determine the power allocation order according to the power magnitudes of the uplink transmissions of each panel.

The UE will first allocate an appropriate power to the first panel with a larger scheduled power, and allocate the remaining power to the second panel with a smaller scheduled power. When the power magnitudes of the first uplink transmission and the second uplink transmission are also the same, the UE further determines the power allocation order according to the transmission timing of the uplink transmissions. The UE will first allocate an appropriate power to the first panel with an earlier transmission timing, and allocate the remaining power to the second panel with a later transmission timing.

[0082] In operation S3070, the UE determines the UL transmission power value of each panel according to the scheduled power value of each panel, the second maximum output power value of this panel, and the first maximum output power value.

For a detailed description of how to determine the power allocation order of the panels and how to allocate the uplink power values of each panel, reference can be made to the relevant description of the embodiment in Figure 9 , which will not be elaborated here.

[0094] In operation S30716, based on the comparison result of the sum of at least one second output maximum power value and the scheduled power value of at least one panel with the first output maximum power value, the UE determines that the UL transmission power value of at least one panel corresponding to the at least one second output maximum power value is its second output maximum power value; at the same time, based on the same comparison result, it determines that the uplink transmission power value of at least one panel corresponding to the at least one scheduled power value is its scheduled power value.
[0095] For example, when the scheduled power value P scheduling,panel1 of the first panel is greater than (>) its second output maximum power value P cmax,panel1 , and the scheduled power value P scheduling,panel2 of the second panel is less than or equal to (<=) its second output maximum power value P cmax,panel2 , the UE will compare the sum of the second output maximum power value P cmax,panel1 of the first panel and the scheduled power value P scheduling,panel2 of the second panel with the first output maximum power value P cmax,UE . When the sum of P cmax,panel1 and P scheduling,panel2 is less than or equal to the first output maximum power value P cmax,UE , the UE will set P cmax,panel1Determine the UL transmission power value for the first panel and set P scheduling,panel2 as the uplink transmission power value for the second panel.

[0100] For example, when the sum of the scheduling power value P scheduling,panel1 of the first panel and the scheduling power value P scheduling,panel2 of the second panel is less than or equal to (<=) the first output maximum power value P cmax,UE , the UE will compare P scheduling,panel1 with the second output maximum power value P cmax,panel1 of the first panel, and compare P scheduling,panel2 with the second output maximum power value P cmax,panel2 of the second panel. When P scheduling,panel1 is less than or equal to (<=) the second output maximum power value P cmax,panel1 of the first panel, and P scheduling,panel2 is less than or equal to (<=) the second output maximum power value P cmax,panel2 of the second panel, the UE will determine P scheduling,panel1 as the UL transmission power value of the first panel and set P scheduling,panel2 as the uplink transmission power value of the second panel.

[0105] For example, when the sum of the scheduled power value P of the first panel scheduling,panel1 and the scheduled power value P of the second panel scheduling,panel2 is less than or equal to (<=) the first output maximum power value P cmax,UE , the UE compares the scheduled power value P of the first panel scheduling,panel1 with the second output maximum power value P of the first panel cmax,panel1 , and compares the scheduled power value P of the second panel scheduling,panel2 with the second output maximum power value P of the second panel cmax,panel2 . When the scheduled power value P of the first panel scheduling,panel1 is greater than (>) the second output maximum power value P cmax,panel1 , and the scheduled power value P of the second panel scheduling,panel2 is less than or equal to (<=) the second output maximum power value P cmax,panel2 , the UE takes the second output maximum power value P of the first panel cmax,panel1 as the uplink transmission power value of the first panel, and takes the scheduled power value P of the second panel scheduling,panel2 as the uplink transmission power value of the second panel.

[0109] In operation S30734, the UE determines the uplink transmission power value of each panel based on the comparison result between the scheduled power value of each panel and its corresponding second output maximum power value, and according to at least one parameter. The at least one parameter includes at least one of the following information: the priority of uplink transmission of each panel, the power magnitude of uplink transmission of each panel, and the time of uplink transmission of each panel.

For a detailed description of how to determine the power allocation order of each panel and how to allocate the uplink transmission power value for each panel, reference can be made to Figure 9 the relevant embodiment descriptions in
[0110] For example, when the sum of the scheduled power value P scheduling,panel1 of the first panel and the scheduled power value P scheduling,panel2 of the second panel is greater than (>) the first output maximum power value P cmax,UE , the UE will compare the scheduled power value P scheduling,panel1 of the first panel with the second output maximum power value P cmax,panel1 of the first panel, and compare the scheduled power value P scheduling,panel2 of the second panel with the second output maximum power value P cmax,panel2 of the second panel.
