Specifically, embodiments of the present invention provide a power parameter determining method, an indicating method, a terminal and a network device, which solve the problems in the prior art that data transmissions with different priorities collide on the same resource and a low-priority service interferes with a high-priority service.

In a 5G system, URLLC (Ultra Reliable Low Latency Communications) service with extremely high Latency and high reliability requirements occurs sporadically and irregularly, so that multiplexing transmission of the service on the same resource for transmitting other services with different requirements is supported, which helps to reduce transmission Latency. When the network device schedules service transmissions of different priorities of different terminals, it may happen that data transmissions of two different priorities collide on the same resource, for example, after the network device schedules an eMBB (enhanced Mobile Broadband) service, a service request of another terminal for scheduling a URLLC is received, and the resource of the URLLC service may collide with the scheduled eMBB service. In order to ensure the high reliability and low delay requirements of the URLLC service with high priority and avoid the interference of eMBB service, the transmission power of a service channel can be adjusted, larger open-loop power parameters are configured, and the interference elimination performance of a receiving end is improved, so that the performance loss caused by resource overlapping on the service channel with high priority is reduced.

As shown in fig. 1, an embodiment of the present invention provides a method for determining a power parameter, which is applied to a first terminal, and includes:

step 11, if a Physical Uplink Shared Channel (PUSCH) resource sent by the first terminal is at least partially overlapped with a PUSCH resource sent by the second terminal, obtaining a mapping relationship between a candidate open-loop power parameter pair and indication state information; and the priority of the first terminal for sending the PUSCH resources is higher than the priority of the second terminal for sending the PUSCH resources.

Specifically, the determining that the PUSCH resource of the first terminal and the PUSCH resource of the second terminal at least partially overlap may be: when a first terminal transmits a URLLC PUSCH by using an activated uplink BWP (Bandwidth Part), a serving cell, and a carrier frequency using a parameter set number and the PUSCH power control adjustment parameter state number, the URLLC PUSCH is the ith transmission of the first terminal, for example: transmitting on the 4 th and 5th symbols on the time slot n; and before the URLLC PUSCH is scheduled, other terminals (such as a second terminal) are already scheduled with embbbpusch on slot n, and the eMBB PUSCH and the URLLC PUSCH have resource overlap.

Step 12, obtaining target indication state Information indicated by DCI (Downlink Control Information) by the network device.

Specifically, the target indication state information is one of the indication state information, so that the first terminal knows the open loop power parameter pair for power boost corresponding to the target indication state information according to the target indication state information and the mapping relationship.

And step 13, determining a target open-loop power parameter in the candidate open-loop power parameters according to the mapping relation and the target indication state information.

Specifically, the target open-loop power parameter is an open-loop power parameter pair used for power boosting of the first terminal transmitting the high-priority service.

In the above embodiment of the present invention, under the condition that the PUSCH resource sent by the first terminal and the PUSCH resource sent by the second terminal are at least partially overlapped, the mapping relationship between the candidate open-loop power parameter pair and the indication status information is obtained, the target indication status information indicated by the network device through the downlink control information DCI is obtained, and the target open-loop power parameter in the candidate open-loop power parameter is determined according to the mapping relationship and the target indication status information, where the priority of sending the PUSCH resource by the first terminal is higher than the priority of sending the PUSCH resource by the second terminal, and power boosting can be performed on a high-priority traffic channel by determining the target open-loop power parameter, so as to ensure transmission of a high-priority traffic.

Further, before step 12, the method may further include:

Specifically, the network device configures an open-loop power parameter pair according to a first higher layer signaling parameter (i.e., multiplexing an existing higher layer signaling parameter). Wherein the candidate pair of open-loop power parameters is a portion of the pair of open-loop power parameters or the candidate pair of open-loop power parameters is the entirety of the pair of open-loop power parameters. The pair of open-loop power parameters is configured in pairs, and the pair 32 may be configured by a first higher layer signaling parameter, which is not specifically limited herein.

Further, the mapping relationship is a preset mapping relationship, or a mapping relationship configured by the network device through a second high-level signaling parameter.

Specifically, the mapping relationship may be a predefined mapping relationship between the first terminal and the network device, or a mapping relationship configured by the network device through the second high-level signaling parameter.

Further, after the step 13, the method may further include:

Specifically, the transmission power of the first terminal for PUSCH resource transmission is determined according to the target open loop power parameter, and power boosting can be performed on a high-priority traffic channel, so as to reduce performance loss caused by resource overlapping on the high-priority traffic channel.

Further, when the first terminal transmits the PUSCH using the activated uplink BWP, the serving cell, and the carrier frequency using the parameter set number and the PUSCH power control adjustment parameter state number, the first terminal determines that the transmission power of the ith PUSCH transmission opportunity is: the maximum power configurable by the first terminal is a value of target power, or a value obtained by adding a logarithmic value (the product of the power of 2 mu and the PUSCH resource allocation bandwidth) with 10 times of log being base 10, adding a value of a product of a path loss compensation factor and a path loss compensation parameter, adding a power offset value and adding a closed loop power adjustment parameter; the minimum value of the two is the transmission power.

The determining of the transmission power of the first terminal for PUSCH resource transmission may specifically be obtained by the following formula:

wherein b is an activated upstream bandwidth part BWP;

f is a carrier frequency;

c is a serving cell;

j is a parameter set number used by the first terminal;

l is a parameter state number;

i is the ith transmission opportunity of the PUSCH at the first terminal;

P_{PUSCH，b，f，c}(i，j，q_dl) is the transmit power;

P_CMAX，f，c(i) a configurable maximum power for the first terminal;

P_{0_PUSCH，b，f，c}(j) a target power for performing PUSCH resource transmission for the first terminal;

mu is a subcarrier interval configuration number;

allocating bandwidth for the PUSCH resource, wherein the bandwidth indicates the number of Radio Bearers (RBs) allocated;

α_b，f，c(j) a path loss compensation factor;

PL_b，f，c(q_d) A path loss compensation parameter;

q_da pilot Resource sequence number used in path loss configured for RRC (Radio Resource Control);

Δ_{TF，b，f，c}(i) is a power offset value;

f_b，f，c(i, l) is a closed loop power adjustment parameter;

dBm is the unit of transmitting power;

P_{0_PUSCH，b，f，c}(j) and alpha_b，f，c(j) Is a target open loop power parameter.

The target power may be a target SINR (Signal to Interference plus Noise Ratio) of the first terminal traffic transmission, i.e. a Ratio representing the strength of the received useful Signal and the strength of the received Interference Signal (Noise and Interference). Different service types require different target SINR, and 5G supports service types such as URLLC, eMBB, mMTC (massive Machine Type of Communication) and the like. The power offset value is related to factors such as coding rate, modulation order, etc.

In the above embodiment of the present invention, under the condition that PUSCH resources transmitted by a first terminal and PUSCH resources transmitted by a second terminal are at least partially overlapped, a mapping relationship between a candidate open-loop power parameter pair and indication status information is obtained, target indication status information indicated by network equipment through downlink control information DCI is obtained, and a target open-loop power parameter in the candidate open-loop power parameter is determined according to the mapping relationship and the target indication status information, where a priority of PUSCH resources transmitted by the first terminal is higher than a priority of PUSCH resources transmitted by the second terminal, and power boost may be performed on the first terminal transmitting a high-priority service by determining the target open-loop power parameter, so as to ensure transmission of the high-priority service.

As shown in fig. 2, an embodiment of the present invention further provides a method for indicating a power parameter, which is applied to a network device, and includes:

step 21, if the PUSCH resource sent by the first terminal is at least partially overlapped with the PUSCH resource sent by the second terminal, sending the target indication state information indicated by the DCI to the first terminal; and the priority of the first terminal for sending the PUSCH resources is higher than the priority of the second terminal for sending the PUSCH resources.

In the above embodiments of the present invention, in a case where PUSCH resources transmitted by a first terminal at least partially overlap PUSCH resources transmitted by a second terminal, status information is indicated by transmitting target indication indicated by DCI to the first terminal; the priority of the PUSCH resource sent by the first terminal is higher than that of the PUSCH resource sent by the second terminal, and the target open-loop power parameter can be determined and sent to the first terminal, so that the power of the first terminal is improved, and the transmission of a high-priority service is ensured.

Further, before step 21, the method may further include:

Specifically, the network device configures an open-loop power parameter pair by using a first high-level signaling parameter (that is, multiplexing an existing high-level signaling parameter), and determines at least one part of the open-loop power parameter pair as a candidate open-loop power parameter pair according to the open-loop power parameter pair, that is, the candidate open-loop power parameter pair is one part of the open-loop power parameter pair, or the candidate open-loop power parameter pair is all the open-loop power parameter pairs. For example: the network device configures 5 open-loop power parameter pairs through a first high-level signaling parameter, wherein the number j of the 5 open-loop power parameter pairs is 2, 3, 4, 5, and the open-loop power parameter pair is a candidate open-loop power parameter pair which is configured for the network device and can be used for power boost.

Wherein, the open loop power parameter pair is configured in pairs, and 32 pairs can be configured by the first high layer signaling parameter. The number of the open-loop power parameter pairs and the candidate open-loop power parameter pairs is not particularly limited herein.

Further, before step 21, the method may further include:

Specifically, the mapping relationship may be a mapping relationship configured by the network device through a second higher layer signaling parameter, or the mapping relationship may be a mapping relationship predefined by the first terminal and the network device; and when the mapping relationship is the mapping relationship configured by the network device through the second high-level signaling parameter, the network device needs to send the mapping relationship between the candidate open-loop power parameter pair configured by the second high-level signaling parameter and the indication state information to the first terminal.

Further, when the number of the pairs of open-loop power parameters includes J, the determining that at least one part of the pairs of open-loop power parameters is a candidate pair of open-loop power parameters may specifically include one of the following:

the first method is as follows: and according to the sequence of the J open-loop power parameter pairs, configuring M open-loop power parameter pairs as candidate open-loop power parameter pairs according to a positive sequence.

Specifically, the network device configures the first M open-loop power parameter pairs { P ] of the open-loop power parameter pairs configured by the first higher layer signaling parameter₀(j) And alpha (J) is used as a candidate open-loop power parameter pair, wherein J belongs to {0, 1, … …, M-1}, M is the number of candidate open-loop power parameter pairs for power boosting configured by the network equipment through the first high-level signaling parameter, M is a positive integer less than or equal to J, and J is the number of open-loop power parameter pairs configured by the network equipment through the first high-level signaling parameter.

The second method comprises the following steps: and configuring N open-loop power parameter pairs as candidate open-loop power parameter pairs according to the sequence of the J open-loop power parameter pairs and the reverse sequence.

Specifically, the network device configures the inverse N open-loop power parameter pairs { P) in the open-loop power parameter pairs configured by the first higher layer signaling parameter₀(j) And alpha (J) is used as a candidate open-loop power parameter pair, wherein J belongs to { J-M, … …, J-1}, N is the number of candidate open-loop power parameter pairs for power boost configured by the network equipment through the first high-level signaling parameter, N is a positive integer less than or equal to J, and J is the number of open-loop power parameter pairs configured by the network equipment through the first high-level signaling parameter.

The third method comprises the following steps: and according to the sequence of the J open-loop power parameter pairs, configuring P open-loop power parameter pairs as candidate open-loop power parameter pairs from the third open-loop power parameter pair according to a positive sequence.

Specifically, the network device configures P open-loop power parameter pairs { P, starting from the third open-loop power parameter pair, in the open-loop power parameter pairs configured by the first higher-layer signaling parameter₀(j) α (j) } as candidatesAnd the open-loop power parameter pairs are set as J ∈ {2, … …, M +1}, P is the number of candidate open-loop power parameter pairs for power boost configured by the network device through the first high-layer signaling parameter, P is a positive integer less than or equal to J, and J is the number of the open-loop power parameter pairs configured by the network device through the first high-layer signaling parameter.

The method is as follows: and according to the sequence of the J open-loop power parameter pairs, configuring Q open-loop power parameter pairs as candidate open-loop power parameter pairs according to a random sequence.

Specifically, the network device randomly selects Q open-loop power parameter pairs { P ] from the open-loop power parameter pairs configured by the first high-level signaling parameter₀(j) And alpha (J) is used as a candidate open-loop power parameter pair, Q is the number of the candidate open-loop power parameter pairs which are configured by the network equipment through the first high-level signaling parameter and are used for power boost, Q is a positive integer less than or equal to J, and J is the number of the open-loop power parameter pairs configured by the network equipment through the first high-level signaling parameter.

In the first, second, third and fourth modes, J is greater than or equal to 0 and less than or equal to 32, M and less than or equal to J, N and P are less than or equal to J, Q is less than or equal to J, and J, M, N, P and Q are positive integers. And, { P₀(j) α (j) } is { P }_{0_PUSCH，b，f，c}(j)，α_b，f，c(j)}。

The following method for determining a nominal open loop power parameter is provided by a specific embodiment:

in the first embodiment:

if the network device configures the terminal J (for example, 8 pairs) of open-loop parameter power parameter pairs to be set as { P } through the first high-layer signaling parameter₀(j) α (J) }, where the number J ∈ {0, 1, … …, J-1 }. It is assumed that the indication status information includes 2bits of indication information, and the number j from the third is 2, 3, 4, 5 of pairs of open-loop power parameters, which are a subset of the previous 8 pairs of open-loop power parameters, for configuring the candidate pairs of open-loop power parameters for power boost for the network device, where the above-mentioned P (here, 4) pairs of candidate pairs of open-loop power parameters are mapped with the 2bits of indication status information as shown in fig. 3. The mapping relationship may be presetMapping relationships (as predefined by the network device and the terminal).

If the network device determines that the indication { P }₀(4) And if the parameter pair of α (4) } is used as the target open-loop power parameter used by the terminal for power boost, the network device sends target indication status information indicated by the DCI to the first terminal, where the target indication status information includes "10".

The terminal determines { P "in the candidate open-loop power parameter pairs through a mapping relation between predefined indication state information and the candidate open-loop power parameter pairs with the number j of 2, 3, 4 and 5 in the set of 8-split-loop power parameter pairs and through target indication state information '10' acquired by the terminal₀(4) And alpha (4) } is used as a target open loop power parameter for high priority traffic transmission.

Example two:

if the network device configures the terminal J (for example, 8 pairs) of open-loop parameter power parameter pairs to be set as { P } through the first high-layer signaling parameter₀(j) α (J) }, where the number J ∈ {0, 1, … …, J-1 }. Assuming that the indication status information includes 1-bit indication information, and the number j from the third is 2, 3 of pairs of open-loop power parameters, which are subsets of the previous 8 pairs of open-loop power parameters, for configuring the candidate pairs of open-loop power parameters for power boost for the network device, the mapping relationship between the 2 pairs of candidate open-loop power parameters and the 1-bit indication status information is shown in fig. 4. The mapping relationship may be a mapping relationship configured by the network device through a second higher layer signaling parameter.

If the network device determines that the indication { P }₀(3) And if the parameter pair of α (3) } is used as the target open-loop power parameter used by the terminal for power boost, the network device sends target indication status information indicated by the DCI to the first terminal, where the target indication status information includes "1".

The terminal detects the mapping relation between the indication state information configured by the network equipment through the second high-level signaling parameter and the candidate open-loop power parameter pair with the number j being 2 and 3 in the set of 8 split-loop power parameter pairs, and determines to use the target indication state information '1' acquired by the terminal{ P of candidate open-loop power parameter pairs₀(3) And alpha (3) } is used as a target open loop power parameter for high priority traffic transmission.

Example three:

if the network device configures the terminal J (for example, 8 pairs) of open-loop parameter power parameter pairs to be set as { P } through the first high-layer signaling parameter₀(j) α (J) }, where the number J ∈ {0, 1, … …, J-1 }. It is assumed that the indication status information includes 2bits of indication information, and the number j from the first is 0, 1, 2, 3 of pairs of open-loop power parameters, which are a subset of the previous 8 pairs of open-loop power parameters, for configuring the network device as a candidate pair of open-loop power parameters for power boost, where the above M (here, 4) pairs of candidate pairs of open-loop power parameters are mapped to the 2bits of indication status information as shown in fig. 5. The mapping relationship may be a preset mapping relationship (e.g., predefined by the network device and the terminal).

If the network device determines that the indication { P }₀(1) And if the parameter pair of α (1) } is used as the target open-loop power parameter used by the terminal for power boost, the network device sends target indication status information indicated by the DCI to the first terminal, where the target indication status information includes "01".

The terminal determines { P "in the candidate open-loop power parameter pairs through a mapping relation between predefined indication state information and the candidate open-loop power parameter pairs with the number j of 0, 1, 2 and 3 in the set of 8-split-loop power parameter pairs and through target indication state information '01' acquired by the terminal₀(1) And alpha (1) } is used as a target open loop power parameter for high priority traffic transmission.

Example four:

if the network device configures the terminal J (for example, 10 pairs) of open-loop parameter power parameter pairs to be set as { P } through the first high-layer signaling parameter₀(j) α (J) }, where the number J ∈ {0, 1, … …, J-1 }. Suppose the indication status information includes 2-bit indication information, and the last open-loop power parameter pair with the number j being 6, 7, 8, 9 is the candidate open-loop power parameter pair configured for the network device for power boost, and the N (here, 4) candidate open-loop power parameter pairs are provided for the network deviceFor the subset of the open-loop power parameter pairs of the previous 10, the mapping relationship between the 4 candidate open-loop power parameter pairs and the 2bits indication status information is shown in fig. 6. The mapping relationship may be a mapping relationship configured by the network device through a second higher layer signaling parameter.

If the network device determines that the indication { P }₀(9) And if the parameter pair of α (9) } is used as the target open-loop power parameter used by the terminal for power boost, the network device sends target indication status information indicated by the DCI to the first terminal, where the target indication status information includes "11".

The terminal detects the mapping relation between the indication state information configured by the network equipment through the second high-level signaling parameter and the candidate open-loop power parameter pair with the serial number of j being 6, 7, 8 and 9 in the set of 10 split-loop power parameter pairs, and determines { P (P) in the candidate open-loop power parameter pair through the target indication state information '11' acquired by the terminal₀(9) And alpha (9) } is used as a target open loop power parameter for high priority traffic transmission.

Example five:

if the network device configures the terminal J (for example, 10 pairs) of open-loop parameter power parameter pairs to be set as { P } through the first high-layer signaling parameter₀(j) α (J) }, where the number J ∈ {0, 1, … …, J-1 }. Assuming that the indication status information includes 2-bit indication information, the open-loop power parameter pairs with the random sequence number j being 2, 4, 7, and 9 are candidate open-loop power parameter pairs configured for the network device for power boost, the Q (here, 4) candidate open-loop power parameter pairs are subsets of the former 10 open-loop power parameter pairs, and the mapping relationship between the 4 candidate open-loop power parameter pairs and the 2-bit indication status information is shown in fig. 7. The mapping relationship may be a mapping relationship configured by the network device through a second higher layer signaling parameter.

If the network device determines that the indication { P }₀(7) And if the parameter pair of α (7) } is used as the target open-loop power parameter used by the terminal for power boost, the network device sends target indication status information indicated by the DCI to the first terminal, where the target indication status information includes "10".

The terminal detects the network equipment communicationMapping relation between indication state information configured by second high-layer signaling parameters and candidate open-loop power parameter pairs with the serial number j of 2, 4, 7 and 9 in a 10-split-loop power parameter pair set, and determining { P ' in the candidate open-loop power parameter pairs through target indication state information ' 10 ' acquired by a terminal₀(7) And α (7) } as the target open loop power parameter for high priority traffic transmission.

In the above embodiments of the present invention, in a case where PUSCH resources transmitted by a first terminal at least partially overlap PUSCH resources transmitted by a second terminal, the indication is made by transmitting DCI to the first terminal; the priority of the PUSCH resource sent by the first terminal is higher than that of the PUSCH resource sent by the second terminal, and the power of a service channel for transmitting high priority can be improved by multiplexing the existing high-level signaling parameter and indicating the target indication state information through the DCI, so that the transmission of high priority service is ensured.
