Description

Method and device for determining power control parameter, storage medium and electronic equipment

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for determining a power control parameter, a storage medium, and an electronic device.

Background

Currently, a new generation radio communication (NR) technology is being defined, and as a fifth generation mobile communication system, the technology needs to support different types of application scenarios, and also needs to support a conventional frequency band, a new high frequency band, and a beam mode at the same time, which brings a great challenge to design of power control.

The power control of uplink transmission is related to many factors, such as path loss, target received power, maximum transmit power, closed loop power adjustment, transmission bandwidth, transmission rate, etc. In the NR, the uplink transmission at least includes a physical uplink shared channel PUSCH, a physical uplink control channel PUCCH, a sounding reference signal SRS, and a physical random access channel PRACH. Uplink transmission can be scheduled periodically by the base station or dynamically, and the UE can also decide to send PRACH itself. NR supports frequency division multiplexing for multiple uplink transmissions, so multiple transmissions can be sent in parallel.

When the base station schedules more than one uplink transmission for the user terminal UE, the corresponding beams between the multiple uplink transmissions are not completely consistent. Limited by the capability of the UE, the UE cannot simultaneously transmit using the corresponding beam according to the scheduling information of each uplink transmission, and then the UE may change the beam of part of the uplink transmissions. Since there is a corresponding relationship between the beam and the power, the corresponding transmission power will also change after the beam is changed.

In the related art, no solution has been proposed in the related art for the problem that the uplink transmission after the beam change cannot obtain the corresponding power control parameter when multiple uplink transmissions need to be simultaneously transmitted.

Detailed Description

The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

In order to more clearly explain the technical solutions involved in the present embodiment, some technical terms are further explained below:

in a wireless communication system, transmission power control of transmissions is required in order to reduce power consumption of a transmitting device and to reduce interference caused by unnecessary high-power transmissions to other transmissions. Factors such as the size of the communication range, the maximum transmission power and reception sensitivity of the transceiver devices of both communication parties, the modulation and coding scheme and rate of data, the operating frequency band, and the bandwidth occupied by transmission all affect the transmission power. Generally, it is necessary to use a lower transmission power as much as possible under the condition that the received signal quality requirement of the receiving end is satisfied.

In a general communication technique, a communication node 1 transmits a reference signal, and a communication node 2 measures a Path Loss (PL) from the node 1 to the node 2 based on the reference signal. PL is calculated using the difference between the transmission power of the reference signal at node 1 and the reception power of the reference signal received at node 2. Assuming that the PL of the node 2 to node 1 transmission channel is the same as the PL of the node 1 to node 2 channel, the node 2 can calculate the transmission power of the node 2 as the transmitting node to node 1 with the above-mentioned PL. Since PL is the result of a unilateral measurement, this factor belongs to the open loop part in the transmission power. The node 1 receives the transmission and analyzes the transmission, and provides power adjustment information for the node 2 according to the received quality, and the process belongs to closed-loop power control.

In LTE, the base station to terminal link is the downlink and the terminal to base station link is the uplink. The downlink power is determined by the base station based on the channel measurements of each scheduled UE and the scheduling algorithm. The power control of the uplink is an open loop combined with a closed loop approach. In addition, certain quantities related to the transmission, such as the transmission rate, MCS level, transmission bandwidth, etc., also affect the power.

The following is a transmission power calculation formula of PUSCH in LTE, and each parameter affecting power will be described by taking this as an example.

In a carrier aggregation (carrier aggregation) scenario, each UE supports a plurality of Component Carriers (CCs), and each CC is also called a serving cell. The subscript c in the above equation refers to the serving cell c. As can be seen from the above equation, the transmission power in the power calculation equation is calculated for the serving cell.

The open loop part of the power of uplink transmission PUSCH is determined by target receiving power, path loss PL and path loss factor α, wherein the target receiving power is divided into cell level and UE level parameters, which are determined by the base station and configured to the UE, and the closed loop part is that the base station determines the closed loop power Control adjustment quantity according to the difference between the measurement result and the target to transmit power Control Command (TransmitPower Control Command, TPC Command, that is, delta aiming at PUSCH in DCI_PUSCH) The UE is informed. UE maintains a local power adjustment quantity f (i), updates according to a transmission power control command, and achieves the purpose of closed-loop power control by adopting the formula; where i is the subframe number, Δ TF is the MCS-dependent power offset, and is the maximum power limit of the UE.

The cell-level target received power P0_ nominal of LTE is obtained by distinguishing PUSCH (semi-static, dynamic, message 3MSG3) and PUCCH, and corresponds to different Block Error rate (BLER) requirements. The UE level target received power parameter P0_ UE _ specific is also set to distinguish the above items in order to compensate systematic deviations, such as PL estimation errors, errors in absolute output power setting.

Updating f (i) according to the transmission power control command is divided into two modes: the method comprises an accumulative method and an absolute value method, wherein the absolute value method is to directly update the local closed-loop power adjustment amount f (i) of the UE by using a transmission power control command sent by the base station, and the accumulative method determines the local closed-loop power adjustment amount f (i) of the UE by the transmission power control command sent by the base station and a historical value of the local closed-loop power adjustment amount of the UE. Note that f (i) here represents the amount of closed loop power adjustment local to the UE. For PUCCH transmission, the subscript is ignored, and the UE-local closed-loop power control adjustment amount in the power control formula is denoted by g (i), and is a UE-local closed-loop power adjustment amount for PUCCH, similar to the f (i) meaning of PUSCH.

The local closed loop power adjustment amount f (i) of the UE is also called power control adjustment state (power control adjustment state).

In the 5G technology, the power control of the uplink transmission is at the BWP level, that is, the transmit power is determined for each BWP level uplink transmission.

The 5G technology introduces a beam transmission mode, and both the base station and the UE support multiple beams. When operating in beam mode, the power calculation needs to take into account the characteristics of the beam. The resources used for the path loss measurement in 5G are related to the beam of the transmission path, and need to be configured by the base station, so the path loss measurement parameter exists independently of the open-loop power control parameter and the closed-loop power control parameter.

If the UE supports multiple beams (or beam groups), the base station configures an association between each possible beam (or beam group) and the power control parameters. A beam (or group of beams) may be indicated by a reference signal resource. The reference signal resource may be indicated by the base station for uplink transmission of the UE, so that the UE obtains a power control parameter associated with the reference signal resource.

The reference signal resource includes at least one of: uplink Sounding Signal (SRS), Channel State Information Reference Signal (CSI-RS), Secondary Synchronization Block (SSB), Phase Tracking Reference Signal (PTRS), Tracking Reference Signal (TRS), and Demodulation Reference Signal (DMRS).

Example 1

In this embodiment, a method for determining a power control parameter is provided, and fig. 1 is a flowchart of a method for determining a power control parameter according to an embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:

step S102, acquiring first transmitted airspace resource information and second transmitted airspace resource information;

step S104, adjusting at least part of spatial domain resource information of the first transmission according to the following objects:

spatial domain resource information of the second transmission, or,

spatial resource information of the first transmission and spatial resource information of the second transmission, or,

a set of spatial domain information resources associated with a first transmission and spatial domain resource information of a second transmission;

and step S106, determining at least part of power control parameters of the first transmission according to the adjusted spatial domain resource information of the first transmission.

Through the above steps, in the process of sending the first transmitted spatial domain resource information and the second transmitted spatial domain resource information, the first transmitted spatial domain resource information may be adjusted according to the second transmitted spatial domain resource information and the first transmitted spatial domain resource information or the set of spatial domain information resources associated with the first transmission, and at least part of the power control parameters of the first transmission may be obtained according to the adjusted first transmitted spatial domain resource information.

Meanwhile, the optimal power control solution of different beam collision scenes can be flexibly realized through the steps.

Specifically, the first transmitted spatial domain resource information includes at least one spatial domain resource information, and the adjusted first transmitted spatial domain resource information includes only the adjusted spatial domain resource information part, and the unadjusted part is still the original first transmitted spatial domain resource information. For example, the first transmission is a PUSCH, and the spatial resource information of the original first transmission includes 2 spatial resource information, where each spatial resource information is represented by an SRS resource, and the identifiers of the 2 spatial resource information are SRS-1 and SRS-2, respectively. The second transmission is a PUCCH, and the spatial resource information of the second transmission comprises 1 spatial resource information which is represented by a spatial relationship and is marked as a spatial relationship-1.

Assuming that spatial relationship-1 can be transmitted simultaneously with SRS-1 but cannot be transmitted simultaneously with SRS-2, spatial relationship-1 forms second spatial resource information of the first transmission in place of SRS-2. That is, the spatial domain resource information of the first transmission PUSCH includes two spatial domain resource information SRS-1 and SRS-2, one of which is adjusted to have a spatial relationship of-1, and the adjusted spatial domain resource information is adjusted to be the adjusted spatial domain resource information of the first transmission. Assuming that SRS-1 and SRS-2 determine a set of power control parameters, respectively, the adjusted first transmission still supports two sets of power control parameters, which are determined by SRS-1 and spatial relationship-1, respectively.

The main body of the above steps may be a base station, a UE, etc., but is not limited thereto. In a specific implementation process, the base station and the UE may be replaced by names of various communication nodes, such as nb (nodeb), gNB (gbb), TRP (transmitter receiver point), ap (access point), station, user, STA, relay (relay), and terminal. The base station may also refer to a network side (network), UTRA, EUTRA, and the like.

Uplink transmissions may be configured for the UE by the base station, and such transmissions are typically scheduled periodically, or semi-persistently. The uplink transmission may also be dynamically scheduled by the base station for the UE. In addition, the UE feeds back HARQ ACK/NACK information to the received downlink transmission by using uplink transmission, which may be dynamically scheduled, or may be periodically scheduled or semi-persistently scheduled resources.

Each uplink transmission has determined scheduling information for indicating the time domain, frequency domain and space domain resource information occupied by the uplink transmission. The spatial domain resource information specifically indicates a beam resource for uplink transmission.

To support the beam mode, optionally, the power control parameter of the first transmission includes at least one of: open loop power control parameters, closed loop power control parameters, and path loss measurement parameters.

It should be further noted that the above-mentioned path loss measurement parameters are also referred to as RS parameters of path loss measurement. Each part of the power control parameters supports configuration of a plurality of power control parameters, namely the number of the open-loop power control parameters can be up to J, and the number of each open-loop power control parameter is J; k path loss measurement parameters can be configured at most, and the serial number of each path loss measurement parameter is K; at most, L closed-loop power control parameters can be configured, and the serial number of each closed-loop power control parameter is L; wherein J is an integer greater than 0 and equal to or less than J, K is an integer greater than 0 and equal to or less than K, L is an integer greater than 0 and equal to or less than L, and J, K, L are integers greater than 0.

Specifically, the set of open-loop power control parameters includes at least one of: target received power, path loss factor; the set of path loss measurement parameters includes at least one of: a reference signal resource type indication for path loss measurement, a reference signal resource indication for path loss measurement, and a processing rule of path loss values of reference signals for two or more path loss measurements; the closed loop power control process parameter comprises at least one of the following parameters: the closed loop power control process identification set and the number of the closed loop power control processes.

To further illustrate the method for controlling power control of uplink transmission of a UE according to a power control parameter in this embodiment, the following example is used to describe (the power control parameter here is defaulted to be the power control parameter of the first transmission):

the base station configures J1 open-loop power control parameters (or a set thereof), K1 path loss measurement parameters (or a set thereof), and L1 closed-loop power control parameters (or a set thereof) for PUSCH transmission for the UE.

The base station configures a transmission mode of the PUSCH for the UE, such as codebook-based transmission (codebook based transmission) or non-codebook based transmission (non-codebook based transmission).

The base station configures an uplink sounding signal resource set (SRS resource) based on a PUSCH transmission scheme for the UE, where the uplink sounding signal resource set includes at least one uplink sounding signal resource (SRS resource).

The base station sends Downlink Control Information (DCI) to the UE, where the DCI includes SRS Resource Indicator (SRI), and the SRI may be used to determine precoding for PUSCH transmission. The set of SRIs indicated in DCI for different PUSCH transmission schemes may be different. For example, a set of SRIs for codebook-based transmission may have 2 SRIs, each SRI representing an SRS Resource (Resource); there may be 15 SRIs in the SRI set for non-codebook based transmission, each SRI representing one SRS resource or multiple SRS resources.

The base station configures each member SRI in the SRI set indicated in the DCI for the UE to be associated with at least one of the following: open loop power control parameter (or set thereof) number, path loss measurement parameter (or set thereof) number, closed loop power control parameter (or set thereof) number.

And the base station informs the UE of the power control parameter of PUSCH transmission through the SRI in the DCI.

For PUCCH transmission, there is also a similar method of determining the power control parameter. The differences from the PUSCH are: the beam of the PUCCH is identified by spatial relation information, the base station configures the correlation between the spatial relation information set of the PUCCH and the power control parameter, the spatial relation information transmitted by the PUCCH is indicated by the MAC CE, and the UE determines the power control parameter of the PUCCH according to the correlation between the spatial relation information indicated by the MAC CE and the spatial relation information set of the PUCCH configured by the base station and the power control parameter.

The spatial relationship between the reference signal resource of the PUSCH and the PUCCH is space domain resource information in this embodiment. The spatial domain resource information represents a transmission mode by reference signal resource information, such as SRS or SRI, or a spatial relationship, and the transmission mode may include a beam

the first transmitted spatial resource information and the second transmitted spatial resource information belong to the same class A packet, wherein the class A packet comprises at least one of the following: antenna panel grouping, antenna array grouping;

the adjusted spatial domain resource information of the first transmission and the spatial domain resource information of the second transmission belong to the same C-type group, wherein the C-type group comprises: the arrays are grouped.

It should be further noted that, in accordance with the above-mentioned grouping characteristics between the adjusted spatial domain resources of the first transmission and the second transmission, the adjusted spatial domain resources of the first transmission and the second transmission can be simultaneously transmitted; the above-mentioned grouping feature between the adjusted spatial domain resources of the first transmission and the second transmission is only a way to describe that the adjusted spatial domain resources of the first transmission and the adjusted spatial domain resources of the second transmission can be simultaneously transmitted, and in the field, both the feature or the condition of the adjusted spatial domain resources of the first transmission and the adjusted spatial domain resources of the second transmission in a state of being simultaneously transmitted belong to the protection scope of the present invention.

In addition, not limited to the first transmission and the second transmission in this embodiment, assuming that the spatial domain resource information a and the spatial domain resource information b are provided, whether the spatial domain resource information a and the spatial domain resource information b can be transmitted or received simultaneously may be determined by whether the spatial domain resource information a and the spatial domain resource information b belong to the same group. The specific grouping comprises at least one of the A-type grouping, the B-type grouping and the C-type grouping; the A-type group is called an antenna panel group, a panel group or an antenna array group; the group B is called a sub-antenna panel group, or a sub-antenna array group; the class C packet is called a beam packet.

Or, determining a part of power control parameters of the first transmission according to the adjusted spatial domain resource information of the first transmission, for example, a path loss measurement parameter and an open-loop power control parameter; and determining the rest power control parameters according to the predefined first power control parameter, wherein the closed-loop power control parameter is, for example, the closed-loop power control number is 0.

Or, determining a partial power control parameter of the first transmission, for example, a path loss measurement parameter, according to the adjusted spatial domain resource information of the first transmission; determining a remaining portion power control parameter, e.g., an open loop power control parameter, of the first transmission based on a predefined first power control parameter, taking a predefined value; and the closed-loop power control number is predefined as 0 according to the closed-loop power control parameter.

Or, determining a partial power control parameter of the first transmission, for example, a path loss measurement parameter, according to the adjusted spatial domain resource information of the first transmission; determining remaining power control parameters of the first transmission according to a first power control parameter with a specified number in a power control parameter set configured for the first transmission, for example, open-loop power control parameters in an open-loop power control parameter set with a specified number of 0; and the closed-loop power control number is predefined as 0 according to the closed-loop power control parameter.

Optionally, the power control parameter comprises at least one of: open loop power control parameters, closed loop power control parameters, and path loss measurement parameters.

Optionally, the method in this embodiment further includes:

determining a power control parameter associated with the first transmission based on the spatial domain resource information of the first transmission when the spatial domain resource information of the first transmission and the spatial domain resource information of the second transmission satisfy at least one of the following characteristics:

the first transmitted airspace resource information and the second transmitted airspace resource information meet the spatial relationship quasi co-location condition;

the first transmitted airspace resource information and the second transmitted airspace resource information are related to the same cell group;

the spatial resource information of the first transmission is associated with the same PUCCH group as the spatial resource information of the second transmission.

It should be further noted that, in the above relationship feature, the association relationship may indicate that a direct or indirect association relationship is adopted between two objects. Meanwhile, the power control parameter information obtained according to the power control parameter of the first transmission may be determined in at least one of the following manners:

the path loss measurement parameter in the power control parameter of the first transmission is the corresponding path loss measurement parameter in the mapping relation between the spatial domain resource information configured for the channel of the second transmission and the power control parameter by using the spatial domain resource information of the second transmission;

the path loss measurement parameter of the power control parameter of the first transmission is the path loss measurement parameter of the second transmission;

the open loop power control parameter of the power control parameters for the first transmission uses default values for the first transmission, such as default P0 and alpha configuration values;

the closed-loop power control parameter in the power control parameters of the first transmission uses a default value of the closed-loop power control ID of the first transmission; for example, the closed loop power control number is 0.

And the closed-loop power control parameter in the power control parameter of the first transmission may also use the closed-loop power control parameter corresponding to the spatial resource information of the first transmission in the mapping relationship between the spatial resource information configured for the channel of the first transmission and the power control parameter, and at this time, the local closed-loop power control value of the first transmission is cleared.

Meanwhile, through the above steps, in the case that the difference between the first transmission and the second transmission before and after the beam change is not large in the present embodiment, the original power parameter may be used and the original closed-loop value is inherited; and under the condition that the beam is changed greatly, the PL uses the PL corresponding to the changed beam, and the rest parameters use default values to carry out closed-loop power control reset.

Further, for the cumulative closed loop power adjustment, the first transmission may also use the cumulative value of the local closed loop power adjustment.

For example, when the spatial domain resource information of the second transmission is SRI1, the spatial domain resource information of the first transmission is SRI2, the beam difference between SRI1 and SRI2 is small, or the difference between the respective channel measurement parameters is smaller than a predetermined threshold, the spatial domain resource information of the first transmission is adjusted to be SRI1, but the power control parameter of the first transmission may also use the corresponding power control parameter of the spatial domain resource information configured for the channel of the first transmission and the mapping relationship between the spatial domain resource information configured for the channel of the first transmission and the power control parameter, of the spatial domain resource information before adjustment 2.

detailed description of the preferred embodiment 1

FIG. 2 is a schematic diagram of a beam relationship between a first transmission and a second transmission in accordance with an embodiment of the present invention; as shown in fig. 2, the second transmission uses beam 1 as shown by SRS 1. The UE does not support simultaneous transmission of beam 2 and beam 1 and the UE does not support simultaneous transmission of beam 1 and beam 2.

When a plurality of uplink transmissions have at least partial time domain overlapping, and the spatial domain resource information thereof is not completely consistent and is limited by the capability of the UE, the UE cannot simultaneously transmit some combined beams, that is, the UE cannot transmit according to the spatial domain resource information of each uplink transmission, the UE may perform processing of one of the following schemes:

the first scheme is as follows: not all conflicting uplink transmissions are sent.

That is, according to the processing method of scheme one, neither the first transmission nor the second transmission with overlapping time domains in fig. 2 is transmitted.

And in the second scheme, the uplink transmission with high priority is sent, and the uplink transmission with low priority is discarded.

The maximum transmission power of the uplink transmission with high priority can reach the maximum transmission power of the UE.

Assuming that the priority of the second transmission in fig. 2 is higher, the second transmission is sent and the first transmission is discarded according to the processing method of scheme two.

And thirdly, sending the uplink transmission with high priority according to the scheduling information, adjusting the airspace resource information of the uplink transmission with low priority according to the airspace resource information of the uplink transmission with high priority, and sending the uplink transmission with low priority.

Assuming that the priority of the second transmission in fig. 2 is higher, the second transmission is sent according to the scheduling information according to scheme three, the spatial domain resource information of the first transmission is adjusted according to the spatial domain resource information of the second transmission, and then the first transmission is sent according to the adjusted spatial domain resource information.

For the third scheme, the airspace resource information of the uplink transmission with low priority is adjusted according to the airspace resource information of the uplink transmission with high priority, and the power parameter of the uplink transmission with low priority is determined according to the following mode.

The embodiment of the present invention preferably performs the adjustment of the spatial domain resource information of the first transmission according to the third scheme.

Fig. 3 is a schematic diagram of a beam relationship between a first transmission and a second transmission after adjustment according to an embodiment of the present invention; as shown in fig. 3, the UE can only transmit one beam, and since the priority of the second transmission is high, the first transmission transmits using the beam of the second transmission.

The spatial resource information of the second transmission is used as part of the spatial resource information of the first transmission. For example, the spatial resource information of the second transmission indicates SRS1, the spatial resource information of the first transmission indicates SRS2 and SRS3, and the UE can simultaneously transmit beams represented by SRS2 and SRS3, but cannot support beams simultaneously transmitting SRS1, SRS2, and SRS 3. And adjusting the airspace resource information of the first transmission according to the airspace resource information of the second transmission because the priority of the second transmission is high. The spatial resource information of the first transmission is modified to the SRS1 and the SRS2, or to the SRS1 and the SRS 3. Preferably, the channels represented by SRS2 and SRS3 are used for better transmission quality, e.g., lower PL or lower transmission power.

The partial spatial resource information of the second transmission is used as spatial resource information of the first transmission. For example, the spatial resource information of the second transmission indicates SRS1 and SRS2, the spatial resource information of the first transmission indicates SRS3, and the UE can simultaneously transmit beams represented by SRS1 and SRS2, but cannot support beams simultaneously transmitting SRS1, SRS2, and SRS 3. And adjusting the airspace resource information of the first transmission according to the airspace resource information of the second transmission because the priority of the second transmission is high. The spatial resource information of the first transmission is modified to SRS1 or SRS 2. Preferably, the channels represented by SRS1 and SRS2 are used for better transmission quality, e.g., lower PL or lower transmission power.

The partial spatial resource information of the second transmission is used as the partial spatial resource information of the first transmission. For example, the spatial resource information of the second transmission indicates SRS1 and SRS2, the spatial resource information of the first transmission indicates SRS1 and SRS3, and the UE can simultaneously transmit beams represented by SRS1 and SRS3, but cannot support simultaneous transmission of beams represented by SRS1, SRS2, and SRS 3. And adjusting the airspace resource information of the first transmission according to the airspace resource information of the second transmission because the priority of the second transmission is high. The spatial resource information of the first transmission is modified to SRS1 and SRS 2.
