As shown in fig. 1, a method for reporting terminal capability according to an embodiment of the present invention is applied to a terminal, where the terminal is a multi-antenna radio frequency architecture and supports independent networking SA and/or non-independent networking NSA; the method comprises the following steps:

step 101, reporting the capacity according to the target item;

wherein the target item comprises at least one of:

a working mode;

working state;

transmit diversity TxD capability;

supported power levels.

For example, a 5G single-band dual-antenna high-power terminal with a radio frequency architecture of 23+23dBm or 26+26dBm can be used for capability reporting by applying the method of the embodiment of the present invention.

In this embodiment, optionally, the capability reporting is reporting of a power level, and the reporting of the power level is performed according to the target item. The reporting of the power class may be achieved by reporting the maximum output power.

Optionally, after step 101, the method further includes:

Here, after receiving the power class reported by the terminal in step 101, the network side device can send a power output indication to the terminal in combination with the power limit of the terminal, and schedule the terminal to operate in the indicated power class range. And after receiving the power output indication, the terminal can configure corresponding transmission parameters based on the power output indication.

The power limit may be a maximum output power limit of a terminal allowed in an area corresponding to the network side device (e.g., a base station), or may be a maximum output power limit of a terminal allowed by an operator of the network side device. The transmission parameters configured by the terminal may include a maximum power level, a radio frequency index and a capability corresponding to an applicable power level, and the like.

Wherein the target power level P_EMAX,cMaximum power level P capable of being directly used as terminal transmission_CMAXAlternatively, the terminal is PHR/P_EMAX,cDetermining P for transmission usage for reference_CMAX. Of course, the power output indication is not limited to PHR or P_EMAX,cOther parameters may also be included, which are not listed here.

In this embodiment, optionally, the working modes include an uplink multiple input multiple output (UL-MIMO) mode and a Single antenna port mode;

step 101 comprises:

Therefore, the terminal reports the power level corresponding to the UL-MIMO to the network side equipment based on the UL-MIMO. For example, the radio frequency architecture of the 5G single-band dual-antenna high-power terminal a is 23+23, the reported power levels are all PC2 according to the power levels reported by the actual capabilities of the terminal a during UL-MIMO, and the network side device classifies all such terminals as PC2 terminals.

And the terminal can report the power grade corresponding to the Single antenna port mode to the network side equipment based on the Single antenna port mode. Similarly, for the terminal a, the power class, that is, the PC3, is reported according to the actual capability of the terminal a in the Single antenna port mode, and then the network side device can classify the terminal as a PC3 terminal.

The terminal can also report the power level corresponding to the current working mode to the network side equipment based on the real-time working mode of the terminal, that is, if the terminal is in UL-MIMO, the power level corresponding to the UL-MIMO is reported; and if the terminal is at the Single antenna port, reporting the power level corresponding to the Single antenna port. As mentioned above, terminal a does not support TxD, and reports the power level to PC2 in UL-MIMO and reports the power level to PC3 in single antenna port mode. Therefore, the network side equipment can distinguish the power grades of the terminal in different working modes, and carry out reasonable power output indication aiming at the current working mode of the terminal, for example, PHR corresponding to the power grade is sent to the terminal according to the power grade of the terminal in UL-MIMO, so that network scheduling matched with the actual power grade of the terminal is realized. Thus, the radio frequency architecture is 23+23, and the terminal not supporting TxD can also be applied to a 5G network.

Certainly, the terminals with the same power levels in the two working modes directly report the corresponding power levels, and the network side does not need to perform differential processing.

step 101 comprises:

Similar to the reporting based on the current working mode of the terminal, here, the terminal may also report the power level corresponding to the current working state to the network side device based on the real-time working state of the terminal, that is, if the terminal is in the initial access state, the power level corresponding to the initial access state is reported; and if the terminal is in the connection state, reporting the power level corresponding to the connection state. Therefore, the power level of initial access and the power level of a connection state are distinguished, the network side equipment can select the power level which is allowed to be accessed during initial access according to the power levels of different working states, select other power levels during the connection state according to actual requirements, and configure the terminal to carry out reasonable maximum output power.

For example, power restrictions of different areas or management organizations may be different, some areas have management restrictions that restrict access of high-power terminals, and some areas require use of the high-power terminals, so that such terminals can distinguish between a power level of reporting their initial access and a power level of a connected state, so that a network side device configures the terminals to use higher power levels in the connected state according to the reporting of such terminals and according to area requirements.

In addition, in this embodiment, because the operating state and the operating mode have a correlation, reporting the power level corresponding to the operating mode related to the current operating state can also be achieved based on the current operating state. If the current working state is an initial access state and the relevant working mode is a Single antenna port mode, the terminal reports the power level corresponding to the Single antenna port mode; and if the current working state is a connection state and the relevant working mode is UL-MIMO, the power level corresponding to the UL-MIMO on the terminal is determined.

Optionally, step 101 comprises:

Here, the terminal may support different power class outputs, and the terminal reports all or a part of the power classes that the terminal can support (for example, reports other power classes except the default power class), which is different from a mode of reporting only the maximum power class, and the network side device may determine that the terminal has multiple power classes, so as to select a power class (i.e., a power output indication) allowed by the network or the area to notify the terminal after the terminal is in a connected state according to the area management rule. And finally, the terminal performs the configuration of the maximum allowable output power of the terminal. Wherein the area management specifies a power limit for determining the terminal.

In addition, in this embodiment, the target item further includes a TxD capability, and reporting the capability according to the TxD capability is performed, that is, reporting the TxD as an explicit capability indication according to whether the TxD capability is supported, so that, as described above, the terminal a reports to the PC2 if the TxD capability is supported, and reports to the PC3 if the TxD capability is not supported.

In addition, in this embodiment, the terminal may actively report the capability according to the target item, and may also report the capability according to the target item according to a requirement of the network side device, so optionally, before step 101, the method further includes:

receiving a capability request of network side equipment;

step 101 comprises:

Therefore, after the network side equipment sends the capacity request, the terminal reports the capacity according to the target item in response to the received capacity request so as to meet the requirement of the network side equipment and reduce the signaling consumption.

The capability request is used for indicating the terminal to report the output capability, specifically reporting the terminal power level.

Further, in this embodiment, step 101 includes:

a single frequency band;

multi-band high-power carrier aggregation;

high power supplemental uplink SUL frequency band combining;

high-power multi-system dual-connection MR-DC.

Here, the terminal reports the capability according to the target item under any one working scene of a single-frequency-band multi-band high-power carrier aggregation CA, a high-power SUL frequency band combination, a high-power EN-DC and a high-power MR-DC.

And optionally, in the case that the terminal is in high power carrier aggregation of multiple frequency bands, high power SUL frequency band combination, high power EN-DC, or high power MR-DC, step 101 includes:

For example, when the high-power terminal performs CA of the frequency bands NR1 and NR2, the capability reporting may be performed according to the target item, so as to avoid harmonic or intermodulation interference existing in the frequency band combination NR1 and NR 2.

Similarly, capability reporting according to the target item is also suitable for the situations of high-power SUL frequency band combination, high-power EN-DC and high-power MR-DC, and specifically aims at reporting the power level of the NR frequency band, so as to solve the problem that the ambiguity of the NR reporting power in the above scene can bring about the configuration of power output indication on the network side.

For example, for a 5G single-band dual-antenna high-power terminal, as shown in fig. 2: s201, the base station issues a capability request. S202, the terminal responds to the capability request, and reports the capability according to the target item, specifically, reports based on the power level corresponding to UL-MIMO; or reporting based on the power level corresponding to the Single antenna port mode; or reporting based on power levels corresponding to UL-MIMO and Single antenna port mode (current working mode); or reporting based on the power levels corresponding to the initial access state and the connection state (current working state) of the terminal; or reporting based on the power grade corresponding to the TxD capability; or reporting based on all or part of the power levels supported by the terminal. S203, after receiving the power grade reported by the terminal, the base station judges the power grade supported by the terminal in the connection state, and sends PHR or P in combination with the maximum output power limit value of the terminal allowed in the area_EMAX,cIndicating the equal power output to the terminal, thereby scheduling the terminal to work in the allowed stateWithin a range of power levels. S204, the terminal receives the power output indication and configures the corresponding P_CMAXAnd is suitable for radio frequency indexes and capabilities corresponding to power levels.

For a high-power terminal with 5G NR multi-band carrier aggregation, SUL band combination, MR-DC and EN-DC scene dual antennas, as shown in FIG. 3: s301, the base station issues a capability request. And S302, the terminal responds to the capacity request and reports the capacity to the NR frequency band according to the target item in the scene. When the SUL frequency bands are combined, the capability report can be carried out according to the SUL frequency bands. Specifically, reporting is carried out based on the power grade corresponding to UL-MIMO; or reporting based on the power level corresponding to the Single antenna port mode; or reporting based on power levels corresponding to UL-MIMO and Single antenna port mode (current working mode); or reporting based on the power levels corresponding to the initial access state and the connection state (current working state) of the terminal; or reporting based on the power grade corresponding to the TxD capability; or reporting based on all or part of the power levels supported by the terminal. S303, after receiving the power grade reported by the terminal, the base station judges the power grade supported by the terminal in the NR frequency band or SUL frequency band connection state, and issues PHR or P supporting the corresponding power grade_EMAX,cThe power output is indicated to the terminal so that the terminal is scheduled to operate within the allowed power class range. S304, the terminal receives the power output indication and configures the P corresponding to the NR frequency band or the SUL frequency band_CMAXAnd is suitable for radio frequency indexes and capabilities corresponding to power levels.

The application of the method of the embodiment of the present invention is described below with reference to specific scenarios:

example 1, a high-power terminal of LTE +29dBm (dual antenna 26+26dBm) in long term evolution is controlled by a regional limitation, that is, a terminal with a power level of 29dBm is not allowed to access a network by a B-region operator in the regional limitation, and a terminal with higher capability is also expected to access without relevant regulations for a C-region, a D-region, and the like. The method can distinguish the power level of the initial access state and the power level of the connection state of the terminal, or the terminal reports the power level which can be back-off, when P-MAX is set to null (the actual condition of the LTE network of the operators such as a B area, a C area and the like), the +29dBm terminal can be accessed to the network by PC2(+26dBm) initially (so as to ensure the access limit of the B area to +29dBm), for the operators in the C area and the D area, the operators can control RRC signaling (signaling) through wireless resources to ensure that the terminal (the condition that the UL-MIMO has 29dBm and the Single anti-nna port mode is 26dBm, or the initial access is PC2 but the connection state is +29dBm, or the terminal reports a plurality of supportable or back-off power level conditions), the output capability of the maximum power level (such as +29dBm) is realized after the access, that the terminals have different power levels of different states or the initial access and the power level of the connection state are normally accessed, the terminals can be kept in a state of non-maximum output capacity (such as +26dBm) all the time in the B area, and meanwhile, the introduction requirements of operators such as the C area and the D area on high-power terminals can be met, and the P-MAX setting in the existing network does not need to be changed.

Example 2, PC2(+26dBm) CA _ n3(1.8GHz) +78(3.5GHz), because of harmonic interference, such terminals have Single-shot (Single Tx) capability, that is, there are cases where n3(1Tx) and n78(2Tx) transmit separately or in turn, because n3 does not support high power, and n78 supports high power, there are variations where n3 transmits at 23dBm and n78 transmits at 26dBm, which requires the terminal to report NR power level according to target entries.

Example 3, a PC2(+26dBm) CA _41+79, where the two frequency bands are asynchronously deployed, to avoid performance backoff problems such as sensitivity interference caused by simultaneous transceiving, there is a working scenario where n41(2TX) and n79(2TX) are alternately transmitted, and a power level needs to be reported according to an NR frequency band capability in a PC2 CA in an NR round of transmission, because an NR frequency band radio architecture of the PC2 CA may also be a dual antenna 23+26, a dual antenna 23+23, a single antenna 26, or a single antenna 23, so that in the PC2 CA, a terminal reports an NR power level according to a target item, so that a network side performs matching scheduling according to an NR side power level condition in the CA.

In summary, in the method of the embodiment of the present invention, the multi-antenna radio frequency architecture and the terminal supporting the SA and/or the NSA report the capability according to at least one of the working mode, the working state, the TxD capability and the supported power class, so that the network side device knows the power class of the terminal in the network and performs reasonable configuration, thereby solving the problem of unclear network measurement and configuration caused by unclear power class of a high-power terminal of some radio frequency architectures.

After the network side equipment receives the capability reported by the terminal, the network side equipment judges the power level supported by the terminal in the connection state, and can issue power output instructions such as PHR or PEMAX, c and the like to the terminal according to the maximum output power limit value of the terminal allowed by the area or the operator, and the terminal configures corresponding P after receiving the PHR or PEMAX, c and equal power output instructions indicated by the base station_CMAXAnd the method is suitable for radio frequency indexes and capabilities corresponding to the power grade, so that the network measurement and scheduling of the high-power terminal can be realized within the allowed power grade range.
