Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

When describing the embodiments of the present invention, some concepts used in the following description are first explained.

If the power level capability reported by the terminal is PC3, the maximum transmit power of the terminal is 23dBm; if the power level capability reported by the terminal is PC2, the maximum transmit power of the terminal is 26dBm.

Rel-16 introduces the uplink full power transmission capability. The terminal reports different capabilities according to different radio frequency architectures. There are three options for the uplink full power transmission capability:

Full power mode zero (Full power), full power mode one (Full power Mode1), full power mode two (Full power Mode2).

The uplink full power transmission capability report is based on the radio frequency architecture of the terminal. There are three types of radio frequency architectures:

1) All power amplifiers can reach the maximum transmission power;

2) All power amplifiers cannot reach the maximum transmission power;

3) Some power amplifiers can reach the maximum transmission power.

There may be multiple radio frequency architectures of the terminal. The following example illustrates the radio frequency architecture of a PC2 terminal with two transmitting antennas:

Architecture 1: Both RF links have 26dBm power amplifiers, that is, both links reach full power;

Architecture 2: Both RF links have 23dBm power amplifiers, that is, both links cannot reach full power;

Architecture 3: One RF link has a 26dBm power amplifier, and the other RF link has a 23dBm power amplifier, that is, part of the link reaches full power;

The uplink multi-antenna (Multiple Input Multiple Out, MIMO) transmission specifies the uplink precoding matrix. Taking the two transmitting antennas of the terminal as an example, the NR Rel-15 version standardizes the following precoding matrix:

rank=1 includes two precoding matrices [1 0] and [0 1];

rank=2 contains a precoding matrix

For full power mode zero: when rank=1, the precoding matrix specified above can reach full power, where the power scaling factor is equal to 1, that is, all power is only transmitted on the real transmitting antenna. The terminal of the above-mentioned radio frequency architecture 1 can reach full power.

For full power mode 1: For use in RF architecture 2, when rank=1 in this mode, the precoding matrix is [1 0], [0 1] and [1 1]; [1 1] is a newly introduced one, where the points are divided The power factor is equal to 1/2, that is, only half of the power is transmitted on each antenna; if there are 0 elements in the precoding matrix (for example: [1 0] and [0 1]), the terminal cannot reach full power transmission; if If there is no 0 element in the precoding matrix (for example: [1 1]), the terminal can reach full power transmission; although there are 0 elements when rank=2, the two streams of data are sent from different antennas, so the terminal can reach full power send.

For full power mode 2: Mainly used for RF architecture 3. For example, the power amplifier of the first link is 26dBm, and the power amplifier of the second link is 23dBm, then the terminal reports the network precoding matrix [1 0] can reach full Power transmission, report precoding matrix [0 1] can not reach full power transmission; if the base station schedules the terminal to send uplink data and indicates the precoding matrix [1 0], then the power factor is equal to 1, if the base station schedules the terminal to send uplink data When indicates the precoding matrix [0 1], then the sub-power factor is equal to 1/2. When rank=2, the power factor is equal to 1/2, but the two streams of data are sent from different antennas, so full power transmission can be achieved.

Aiming at the problem of inaccurate power allocation of the terminal under each transmission rank in the prior art, since the current protocol can only support one terminal to report one PC capability, the present invention provides a terminal capability reporting method.

As shown in Figure 1, the terminal capability reporting method includes:

Step 101: Report the power level capability and/or the uplink full power transmission capability according to the uplink transmission rank information.

The transmission rank information may be the number of transmission ranks or the value of the transmission rank. The number of transmission ranks is the number of transmission ranks. For example, if the transmission rank is {rank 1, rank 2}, the transmission rank number is 2; the transmission rank is {rank 1, rank 2, rank 3, rank 4} , Then the number of transmission ranks is 4. Assuming that a terminal has N antennas, when the number of base station receiving antennas is greater than or equal to N, the maximum number of uplink data streams sent by the terminal is N, that is, the number of uplink data streams can be equal to 1, 2... or N, also known as rank 1, Rank 2...or rank N, rank 1, rank 2... or rank N is the uplink transmission rank. For example: when the uplink transmission rank is rank 2, the terminal sends two streams of data.

In this embodiment, when the terminal reports the power level capability and/or the uplink full power transmission capability, it is reported according to the uplink transmission rank information, so that the base station can determine different power configuration mechanisms according to different terminal capability reporting methods, for example: The terminal may separately report a power level capability and/or uplink full power transmission capability for each transmission rank. In this way, when the base station configures the power configuration parameters for the terminal, it configures the power configuration parameters for each transmission rank; or, the terminal sets multiple The transmission rank is divided into at least one transmission rank group, and according to different rank groups, a power level capability and/or uplink full power transmission capability are reported for each transmission rank group, so that when the base station configures power configuration parameters for the terminal, it is Each rank group is configured with power configuration parameters. The base station can configure power configuration parameters for terminals under different transmission ranks, so that power allocation is more accurate, so that the terminals can meet the reported uplink full power transmission capability under different ranks.

Further, when the power level capability is reported according to the uplink transmission rank information, the following three methods are included but not limited to:

method one:

For each transmission rank, the power level capability is reported separately, where each transmission rank corresponds to a power level capability. For example: rank x corresponds to reporting one PC capability, rank y corresponds to reporting another PC capability.

Taking the terminal having two transmitting antennas as an example, the radio frequency architecture is 23+23dBm power amplifier (PA), that is, the terminal has two transmitting power amplifiers of 23dBm each. The terminal reports the following PC capabilities and uplink full power transmission capabilities:

Report PC3 for rank 1, that is, the maximum transmit power is 23dBm;

Report PC2 for rank 2, that is, the maximum transmit power is 26dBm;

The uplink full power transmission capability is reported as: full power mode zero. According to the power level capability and the uplink full power transmission capability, the network side configures the power allocation mechanism for the terminal as: full power mode zero. For example: in the case of rank 2, the terminal has two streams of data reported. To achieve the maximum transmit power of 26dBm, each power amplifier needs to reach 23dBm. From the above RF architecture, it can be seen that the two power amplifiers of the RF architecture can meet full power. . In this embodiment, the terminal can reach full power under any transmission rank.

Way two:

Divide all transmission ranks into at least one transmission rank group, and each transmission rank group includes at least one transmission rank; for different transmission rank groups, respectively report power level capabilities, where the transmission rank group is determined according to the number of transmission ranks, The number of transmission ranks is the number of transmission ranks, and each transmission rank group corresponds to a power level capability.

The terminal reports the corresponding power level capability for each transmission rank group, for example, one power level capability is reported for {rank x, rank y}, and another power level capability is reported for {rank m, rank n}.

The following uses specific examples to illustrate the method of reporting power level capabilities for different transmission rank groups.

Example 1: Taking the terminal with four transmitting antennas as an example, the radio frequency architecture is 23+23+23+23dBm PA. The terminal reports the following PC capabilities and uplink full power transmission capabilities:

Report PC3 for rank 1, that is, the maximum transmit power is 23dBm;

Report PC2 for rank2, rank3, and rank4, that is, the maximum transmit power is 26dBm;

The uplink full power transmission capability is reported as full power mode zero, and the network side configures the power allocation mechanism for the terminal according to the power level capability and the uplink full power transmission capability as: full power mode zero.

In this embodiment, the number of transmission ranks is 4, that is, there are four transmission ranks: rank 1, rank 2, rank 3, and rank 4, rank 1 is a transmission rank group, and the terminal reports PC3; rank 2, rank 3, and rank 4 are another transmission rank group. For rank group, the terminal reports to PC2. Take rank 2 as an example. If the corresponding maximum transmit power is 26dBm, the terminal has two streams of data to report. Two of the four antennas are required, and the power amplifier corresponding to each antenna reaches 23dBm. From the above RF architecture, we can see that Two of the power amplifiers of the RF architecture can meet full power; take rank4 as an example, the corresponding maximum transmit power is 26dBm, the terminal has four streams for data reporting, and four antennas are required, and the power amplifier corresponding to each antenna needs to reach 20dBm. It can be known from the above radio frequency architecture that all four power amplifiers of the radio frequency architecture can meet full power. In this embodiment, the terminal can reach full power under any transmission rank.

Example 2: Taking the terminal with four transmitting antennas as an example, the radio frequency architecture is 23+23+23+20dBm PA. The terminal reports the following PC capabilities and uplink full power transmission capabilities:

Report PC3 for rank 1, that is, the maximum transmit power is 23dBm;

In this embodiment, the number of transmission ranks is 4, that is, there are four transmission ranks: rank 1, rank 2, rank 3, and rank 4, rank 1 is a transmission rank group, and the terminal reports PC3; rank 2, rank 3, and rank 4 are another transmission rank group. For rank group, the terminal reports to PC2. Take rank 4 as an example. If the corresponding maximum transmit power is 26dBm, the terminal has four streams for data reporting. Four antennas are required. To achieve the maximum transmit power of 26dBm, the power amplifier corresponding to each antenna needs to reach 20dBm. It can be seen from the above radio frequency architecture that all four power amplifiers of the radio frequency architecture can meet full power. In this embodiment, the terminal can reach full power under any transmission rank.

Example 3: Taking the terminal with four transmitting antennas as an example, the radio frequency architecture is 23+23+20+20dBm PA. The terminal reports the following PC capabilities and uplink full power transmission capabilities:

Report PC3 for rank1, rank2, and rank3, that is, the maximum transmit power is 23dBm;

Report PC2 for rank4, that is, the maximum transmit power is 26dBm;

In this embodiment, the number of transmission ranks is 4, that is, there are four transmission ranks: rank 1, rank 2, rank3, and rank4. Rank 1, rank 2, and rank 3 are a transmission rank group, and the terminal reports PC3; rank 4 is another transmission rank. Group, the terminal reports to PC2. Take rank3 as an example, the corresponding maximum transmission power is 23dBm, the terminal has three streams for data reporting, and three antennas are required. To achieve the maximum transmission power of 23dBm, the power amplifier corresponding to each antenna needs to reach about 18.7dBm; take rank4 as For example, the corresponding maximum transmit power is 26dBm, the terminal has four streams for data reporting, and four antennas are required. To achieve the maximum transmit power of 26dBm, the power amplifier corresponding to each antenna needs to reach 20dBm; from the above RF architecture, it can be seen , The four power amplifiers of the radio frequency architecture can all meet the full power. In this embodiment, the terminal can reach full power under any transmission rank.

Example 4: The terminal has four transmitting antennas, and the radio frequency architecture is 23+20+20+20dBm PA. The terminal reports the following PC capabilities and uplink full power transmission capabilities:

Report PC3 for rank1 and rank3, that is, the maximum transmit power is 23dBm;

Report PC2 for rank2 and rank4, that is, the maximum transmit power is 26dBm;

In this embodiment, the number of transmission ranks is 4, that is, there are four transmission ranks: rank1, rank2, rank3, and rank4. Rank1 and rank3 are one transmission rank group, and the terminal reports PC3; rank2 and rank4 are another transmission rank group. For rank group, the terminal reports to PC2. Take rank 2 as an example. The corresponding maximum transmit power is 26dBm. The terminal has two streams of data to report. Two antennas are required. To achieve the maximum transmit power of 26dBm, the power amplifier corresponding to each antenna needs to reach 23dBm. It can be seen from the RF architecture that there are some power amplifiers in the RF architecture that cannot reach full power. At this time, the uplink full power transmission capability can also be reported as full power mode zero. In this way, when the network side configures the power allocation mechanism for the terminal, it follows the full power mode Allocate transmit power to terminals under different transmission ranks so that the power amplifier can reach its maximum transmit power as much as possible.

Optionally, way three:

For all uplink transmission ranks, a target power level capability is reported; wherein, the power level capability of each transmission rank corresponding to the target power level capability is indicated through protocol provisions or default rules.

In this embodiment, the terminal only reports one PC capability, that is, the target power level capability. The power level capability corresponding to each transmission rank is determined through protocol regulations or default rules, for example: rank x corresponding PC capability and rank y corresponding PC ability. The target power level capability is the power level capability corresponding to one of all transmission ranks. For example, if the number of transmission ranks is 2, that is, there are two transmission ranks: rank 1 and rank 2; In the target power level capability, the power capability level corresponding to which rank is used as the target power level capability, for example, when the number of transmission ranks is two, the power level capability corresponding to rank 2 is reported. When receiving the target power level capability, the network side determines the power level capability corresponding to each transmission rank according to the protocol.

When the terminal reports the uplink full power transmission capability according to the uplink transmission rank information, it can report according to the radio frequency architecture. When the maximum transmit power is not reached, the full power mode 1 or full power mode 2 is reported; or, according to the uplink transmission rank information, the uplink full power transmission capacity is reported as full power mode zero, which means that all power amplifiers cannot reach the full power mode. When the maximum transmission power is reached or some power amplifiers cannot reach the maximum transmission power, the full power mode zero is also reported.

For example: for the third manner above, if at least part of the power amplifiers in the radio frequency architecture of the terminal cannot reach the maximum transmit power corresponding to the target power level capability, the uplink full power transmission capability is reported as full power mode zero. That is, even if all power amplifiers cannot reach the maximum transmit power corresponding to the target power level capability, the terminal will report the full power mode zero. In this way, when the network side configures the power allocation mechanism for the terminal, it will be based on the agreement or default The rule is to allocate transmit power to terminals under different transmission ranks according to the full power mode, so that the power amplifier can reach its maximum transmit power as much as possible.

Optionally, when the terminal reports the uplink full-power transmission capability according to the uplink transmission rank information, under the power level capability corresponding to the maximum transmission rank, if at least part of the power amplifiers in the radio frequency architecture of the terminal cannot reach the power The maximum transmit power corresponding to the level capability is reported as the uplink full power transmission capability as zero in full power mode.

Taking the terminal with three transmitting antennas as an example, the maximum transmission rank is rank3. If the power level capability corresponding to the rank3 is PC2, the maximum transmission power is 26dBm. The full power required by the three power amplifiers in the radio frequency architecture is about If there are at least some power amplifiers that cannot reach 21.9dBm (such as 20dBm), the uplink full power transmission capability reported by the terminal is also zero in full power mode. In this way, when the network side configures the power allocation mechanism for the terminal, The power mode allocates transmission power to terminals under different transmission ranks, so that the power amplifier can reach its maximum transmission power as much as possible.

Optionally, when reporting the uplink full power transmission capability according to the uplink transmission rank information, the terminal may divide multiple transmission ranks into at least one transmission rank group, and each transmission rank group includes at least one transmission rank group. Rank: For different transmission rank groups, report the uplink full power transmission capability separately, where the transmission rank group is determined according to the number of transmission ranks, and each transmission rank group corresponds to a full power transmission capability. For example, when the number of transmission ranks is 4, rank 1 and rank 2 are one transmission rank group, rank 3 and rank 4 are another transmission rank group, and the uplink full power transmission capability is reported according to the two transmission rank groups.

Specifically, when reporting the uplink full power transmission capability for different transmission rank groups, under the power level capability corresponding to the transmission rank in the transmission rank group, if the terminal can reach the maximum indicated by the power level capability Transmit power, the uplink full power transmission capability is reported as full power mode zero; under the power level capability corresponding to the transmission rank in the transmission rank group, if the terminal cannot reach the maximum transmit power indicated by the power level capability, it is reported The uplink full power transmission capability is full power mode one or full power mode two.

The terminal has 4 transmitting antennas, and the radio frequency architecture is 23+23+20+20dBm PA. The terminal reports the following PC capabilities and uplink full power transmission capabilities:

Report PC2 for rank1, that is, the maximum transmit power is 26dBm;

Report PC3 for rank2 and rank3, that is, the maximum transmit power is 23dBm;

Report PC2 for rank4, that is, the maximum transmit power is 26dBm;

For rank 1, report that the uplink full power transmission capability is full power mode one or full power mode two;

For rank2, rank3, and rank4, report that the uplink full power transmission capability is zero in full power mode;

The network side configures the power allocation mechanism for the terminal according to the power level capability and the uplink full power transmission capability: configure full power mode one or full power mode two for rank1, and configure full power mode zero for rank2, rank3, and rank4.

In this embodiment, the number of transmission ranks is 4, that is, there are four transmission ranks: rank 1, rank 2, rank 3, rank 4, rank 1 is the first transmission rank group, and the reported uplink full power transmission capability is full power mode one or full Power mode two, rank2, rank3, and rank4 are the second transmission rank groups, and the reported uplink full power transmission capability is zero in full power mode. When the network side configures the power allocation mechanism for the terminal, each transmission rank group has a corresponding power configuration mechanism, so that different power configuration mechanisms can be configured for terminals under different transmission ranks, so that the terminal power allocation under each transmission rank more acurrate.

It should be noted that when multiple transmission ranks are divided into at least one transmission rank group, it can be based on whether the terminals under each transmission rank can achieve full power allocation, that is, under any transmission rank in the transmission rank group , The terminal can reach the maximum transmission power indicated by the power level capability corresponding to the transmission rank group.

In the embodiment of the present invention, the terminal reports the power level capability and/or the uplink full power transmission capability according to the uplink transmission rank information, so that the network side can determine different power configuration mechanisms according to different terminal capability reporting methods. The terminals under the transmission rank are configured with power configuration parameters to make the power allocation more accurate, so that the terminals can meet the reported uplink full power transmission capability under different ranks.

As shown in FIG. 2, an embodiment of the present invention provides a method for determining a terminal capability, which is applied to a communication device, and includes:

Step 201: Determine the power level capability and/or the uplink full power transmission capability of the terminal according to the uplink transmission rank information.

The transmission rank information may be a value of the transmission rank, the transmission rank has a corresponding relationship with the power level capability and/or the uplink full power transmission capability, and the protocol specifies the capability information corresponding to the transmission rank. The communication device may be a terminal or a network device. When the communication device is a terminal, the terminal determines the power level capability of all transmission ranks according to the power level capability corresponding to one of the transmission ranks. For example, the number of transmission ranks is two, rank 1 and rank 2, which can be stipulated by agreement. When the power level capability corresponding to rank 1 is PC3, the power level capability corresponding to rank 2 is PC2; or 2 When the corresponding power level capability is PC3, it can be known that the power level capability corresponding to rank 1 is PC2 according to the agreement.

When the terminal reports the power level capability and/or the uplink full power transmission capability, it only needs to report one of the power level capabilities. After receiving the power level capability, the network side can determine the power level capabilities corresponding to the other transmission ranks according to the protocol.

Taking the terminal with two transmitting antennas as an example, the radio frequency architecture is 23+23dBm PA, that is, the terminal has two transmitting power amplifiers of 23dBm each. The terminal reports the following PC capabilities and uplink full power transmission capabilities:

The terminal uses the rank 2 power level capability PC2 as the power level capability reported to the network side;

According to the agreement or default, rank 1 corresponds to PC3, that is, the maximum transmission power is 23dBm;

According to the agreement or default, rank 2 corresponds to PC2, that is, the maximum transmit power is 26dBm;

In this embodiment, the terminal can determine the reported power level capability according to the power level capability of rank 2 according to the agreement. When the network side receives the PC2 capability reported by the terminal, it is determined according to the agreement: the power level capability corresponding to rank 1 is PC3, and the power capability level corresponding to rank 2 is PC2, thereby determining that the terminal's power allocation mechanism under any transmission rank is full Power mode is zero. Taking rank 2 as an example, the power level capability corresponding to rank 2 is PC2, and two streams of data are required to report. The power amplifiers corresponding to the two antennas should meet 23dBm respectively. From the above RF architecture, it can be seen that the two power amplifiers of the RF architecture All can meet full power. In this embodiment, the terminal can reach full power under any transmission rank.

When the communication device is a network device, before determining the power level capability and/or the uplink full power transmission capability of the terminal according to the uplink transmission rank information, the method further includes: receiving uplink transmission rank information .

Since the protocol specifies the corresponding relationship between the transmission rank and the power level capability and/or the uplink full power transmission capability, the network equipment can determine the power level capability and/or uplink corresponding to each transmission rank according to the uplink transmission rank information. Full power transmission capability. For example: the network equipment receives the transmission rank information reported by the terminal as rank1, and the received power level capability reported by the terminal is PC2. According to the agreement, it can be determined that the terminal’s power level capability under rank1 is PC2 and the power level under rank2 The level capability is PC3.

In the embodiment of the present invention, according to the uplink transmission rank information, the power level capability and/or the uplink full power transmission capability of the terminal under each transmission rank can be determined, so that the network side can configure the terminals under different transmission ranks. The power configuration parameters make the power allocation more accurate, so that the terminal can meet the reported uplink full power transmission capability under different ranks.
