detailed description

In a wireless communication system, in order to reduce the power consumption of the transmitting device and reduce the interference caused by unnecessary high-power transmission to other transmissions, it is necessary to perform transmission power control on the transmissions. The size of the communication range, the maximum transmission power and reception sensitivity of the transmitting and receiving devices on both sides of the communication, the modulation and coding method and rate of the data, the operating frequency band, and the bandwidth occupied by the transmission will all affect the transmission power. Generally, it is necessary to use a lower transmission power as far as possible under the condition of meeting the receiving signal quality requirements of the receiving end.

In a general communication technology, a communication node 1 sends a reference signal, and the communication node 2 measures a path loss PL (referred to as a path loss) from node 1 to node 2 according to the reference signal. PL is calculated using the difference between the transmission power of the reference signal of node 1 and the reception power of the reference signal received by node 2. Assuming that the PL of the transmission channel from node 2 to node 1 is the same as the PL of the channel from node 1 to node 2, node 2 can use the above PL to calculate the transmission power of the transmission from node 2 to node 1. Since PL is the result of a unilateral measurement, this factor is part of the open loop in the transmit power. After receiving the transmission, node 1 analyzes it and provides power adjustment information for node 2 according to the received quality. This process belongs to closed-loop power control. Among them, power control can be referred to as power control for short.

In LTE, the link from the base station to the terminal is the downlink, and the link from the terminal to the base station is the uplink. The downlink power is determined by the base station according to the channel measurement results of each scheduling UE and the scheduling algorithm. Uplink power control is a combination of open loop and closed loop. In addition, there are specific quantities related to transmission, such as the transmission rate, modulation and coding strategy (Modulation and Coding Scheme, MCS) level, and transmission bandwidth, which also affect power.

The following is the calculation formula for the transmit power of the PUSCH channel of LTE, taking this as an example to describe the various parameters that affect power.

In a carrier aggregation (Carrier Aggregation) scenario, each UE supports at least one component carrier CC, and each CC is also called a serving cell. The subscript c in the above formula refers to the serving cell. It can be seen from the above formula that the transmit power in the power calculation formula is calculated for the serving cell.

The power of the uplink transmission PUSCH P The open-loop part of _PUSCH is determined by the target received power _{PO_PUSCH} , the path loss amount PL, and the path loss factor α. The target received power is divided into cell-level and UE-level parameters, which are determined by the base station and configured for the UE. The closed-loop part is that the base station determines the closed-loop power control adjustment amount according to the gap between the measurement result and the target, and notifies the UE by transmitting a power control command (Transmit Power Control Command, TPC Command), that is, δ _PUSCH for PUSCH in DCI. The UE maintains a local power adjustment amount f (i), updates it according to the transmitted power control command, and uses the above formula to achieve the purpose of closed-loop power control. Among them, i is a subframe number, _ΔTF is a MCS-related power offset, and _PCMAX is a maximum power limit of the UE.

The LTE cell-level target received power _{PO_PUSCH} distinguishes between PUSCH (semi-static, dynamic, and message 3MSG3) and PUCCH, which respectively correspond to different Block Error Ratio (BLER) requirements. The UE-level target received power parameter P0_UE_specific is also set by distinguishing the above items to compensate for systematic deviations, such as errors in PL estimation errors and absolute output power settings.

Update f (i) according to the transmission power control command is divided into two methods: cumulative and absolute value method, where the absolute value method is to directly update the UE's local closed-loop power adjustment amount f (i) with the transmission power control command sent by the base station, In the cumulative form, the transmission power control command sent by the base station and the historical value of the closed loop power adjustment amount of the UE are used to determine the closed loop power adjustment amount f (i) of the UE. It should be noted that f (i) here represents the closed loop power adjustment amount of the UE. For PUCCH transmission, the meaning of the subscript is ignored. The UE's local closed-loop power control adjustment amount in the power control formula is represented by g (i), which is similar to the meaning of PUSCH's f (i). the amount.

The local closed-loop power adjustment amount f (i) of the UE is also referred to as a power control adjustment state (Power Control Adjustment State).

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

5G technology introduces a beam transmission mode, and both the base station and the UE support multiple beams. When working in beam mode, the power calculation needs to consider the characteristics of the beam. The resources used for 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 parameters exist independently of the open-loop power control parameters and the closed-loop power control parameters.

In order to support the beam mode, the power control parameters are divided into three parts: open-loop power control parameters, closed-loop power control parameters, and reference signal (RS) parameters for path loss measurement. Each part supports multiple configuration, that is, up to J open-loop power control parameters (or its set) can be configured, and the number of each open-loop power control parameter (or its set) is j; road loss measurement parameter (or its (Set) can be configured with a maximum of K, and the number of each path loss measurement parameter (or its set) is k; closed-loop power control parameters (or its set) can be configured with a maximum of L, each closed-loop power control parameter (or its set) Is an integer greater than 0; J is an integer greater than 0 and less than or equal to J; k is an integer greater than 0 and less than or equal to K; l is an integer greater than 0 and less than or equal to L;

The open-loop power control parameters include at least one of the following parameters: target received power and path loss factor; the reference signal (RS) parameters of the path loss measurement include at least one of the following: a reference signal resource indication for path loss measurement An indication of a reference signal resource type used for path loss measurement; the closed-loop power control parameter includes at least one of the following: a closed-loop power control process identifier and a number of closed-loop power control processes.

The open-loop power control parameter set includes at least one of the following: a target received power and a path loss factor;

The path loss measurement parameter set includes at least one of the following: a reference signal resource type indication for path loss measurement, a reference signal resource indication for path loss measurement, and two or more paths of reference signals for path loss measurement. Processing rules for loss values;

The closed-loop power control process parameters include at least one of the following: a closed-loop power control process identifier set, and the number of closed-loop power control processes.

If the UE supports multiple beams (or beam groups), the base station configures the association between each possible beam (or beam group) and open-loop power control parameters, closed-loop power control parameters, and path loss measurement parameters. The beam (or beam group) may be indicated by a reference signal resource.

The reference signal includes at least one of the following: an uplink sounding signal (Sounding Reference Signal, SRS), a channel state information reference signal (Channel Information Information Reference Signal (CSI-RS), a synchronization signal block (secondary, Synchronization, Block, SSB), phase tracking reference Signal (Phase Tracking Reference Signal, PTRS), Tracking Reference Signal (Tracking Reference Signal, TRS), Demodulation Reference Signal (Demodulation Reference Signal, DMRS).

The base station indicates a reference signal resource for the uplink transmission of the UE, so that the UE obtains a power control parameter associated with the reference signal resource.

For example:

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 the PUSCH transmission of the UE.

The base station configures the PUSCH transmission mode 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) for the UE based on the PUSCH transmission mode, which includes at least one uplink sounding signal resource (SRS resource).

The base station sends downlink control information (DCI) for the UE, which includes an SRS resource indicator (SRS), which can be used to determine the precoding of the PUSCH transmission. The SRI set indicated in the DCI for different PUSCH transmission methods may be different. For example, a codebook-based transmission SRI set may have 2 SRIs, each SRI represents a SRS resource (Resource); a non-codebook-based transmission SRI set may have 15 SRIs, each SRI represents a SRS resource or Multiple SRS resources.

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

The base station informs the UE of the power control parameters of the PUSCH transmission through the SRI in the DCI.

Among them, the described uplink transmission includes the following types: PRACH (Physical Random Access Channel, Physical Random Access Channel), PUCCH, PUSCH, SRS.

Example one

An embodiment of the present disclosure provides a power control method. The method includes:

When the transmission of the second frequency domain resource is triggered by the signaling of the first frequency domain resource, or the transmission of the second frequency domain resource is indicated by the signaling of the first frequency domain resource, or the second frequency When the domain resource is activated by the signaling of the first frequency domain resource or the first frequency domain resource is switched to the second frequency domain resource, the first communication node performs one of the following operations:

Determining a power control parameter associated with the transmission of the second frequency domain resource according to the power control parameter associated with the transmission of the first frequency domain resource; and

A path loss parameter associated with the transmission of the second frequency domain resource is determined according to the synchronization signal block SSB.

The method in the embodiment of the present disclosure is executed on a receiving device side, such as a UE. Among them, the frequency domain resources include one of the following: part-bandwidth BWP and component carrier CC.

The embodiments of the present disclosure implement determination of power control parameters in multiple frequency domain resources, and are applicable to a scenario of frequency domain resource switching and a scenario of the same power control grouping. For example, a scenario in which a first frequency domain resource is switched to a second frequency domain resource, and a scenario in which the first frequency domain resource and the second frequency domain belong to the same frequency domain resource group. The power control packet may be a frequency domain resource group.

The synchronization signal block SSB refers to the synchronization signal SS / physical broadcast channel PBCH that the first communication node receives the main information block MIB.

In some embodiments, the first communication node may further perform one of the following operations:

Before transmitting the reference signal of the path loss parameter associated with the transmission of the second frequency domain resource, not transmitting the transmission of the second frequency domain resource in the second frequency domain resource;

Sending the transmission of the second frequency domain resource after the reference signal of the path loss parameter associated with the transmission of the second frequency domain resource is sent;

After the reference signal of the path loss parameter associated with the transmission of the second frequency domain resource is transmitted and the path loss is measured, the transmission of the second frequency domain resource is transmitted.

In detail, the UE is configured with at least one frequency domain resource in some embodiments. Frequency domain resources refer to one of the following: BWP and CC.

As shown in FIG. 1, when the UE is instructed to switch from the first frequency domain resource to the second frequency domain resource, the power control parameter of the second frequency domain resource is determined according to the power control parameter of the first frequency domain resource.

Among them, in a certain frequency domain range, at least one frequency domain resource is limited to only one of the frequency domain resources is activated at a time. It is assumed that at least one BWP is configured in one CC, and only one BWP is activated at a time in each CC. At a certain time t1, BWP1 is activated for at least uplink transmission. At a later time t2, BWP2 is activated for uplink transmission. The power control parameters of BWP1's uplink transmission can be used to determine the power control parameters of BWP2's uplink transmission.

The switching from the first frequency domain resource to the second frequency domain resource may include: the transmission of the second frequency domain resource is triggered or instructed by the first frequency domain resource. The transmission of the first frequency domain resource includes scheduling information for the transmission of the second frequency domain resource. For example, the first frequency domain resource includes scheduling information for uplink transmission of the second frequency domain resource. For example, the DCI of BWP1 contains uplink scheduling information for scheduling uplink transmission PUSCH on BWP2.

Alternatively, switching from the first frequency domain resource to the second frequency domain resource may include: the transmission of the second frequency domain resource is a response to the transmission of the first frequency domain resource. The transmission of the second frequency domain resource includes response information of the transmission of the first frequency domain resource. For example, the PDSCH transmission sent on BWP1, its response information, such as HARQ's positive / negative response, is carried on PUCCH or PUSCH on BWP2.

Alternatively, the handover from the first frequency domain resource to the second frequency domain resource may include: MAC signaling of the first frequency domain resource triggers or instructs the handover to the second frequency domain resource. For example, MAC signaling on BWP1 triggers an uplink transmission to switch to BWP2, or MAC signaling on BWP1 instructs an uplink transmission to switch to BWP2.

Alternatively, switching from the first frequency domain resource to the second frequency domain resource may include: MAC (Media Access Control, Media Access Control) signaling of the first frequency domain resource instructs activation of the second frequency domain resource. For example, MAC signaling on BWP1 indicates that BWP2 is activated for uplink transmission. Since only one BWP can be activated at a time, BWP1 is replaced by BWP2, that is, BWP1 is switched to BWP2.

As shown in FIG. 2, when the UE works on the first frequency domain resource and is instructed to activate the second frequency domain resource, the power control parameter of the first frequency domain resource may be used as a power control parameter for determining the second frequency domain resource. This includes one of the following: the first frequency domain resource is switched to the second frequency domain resource; the first frequency domain resource and the second frequency domain resource are both in an activated state.

For example, when the UE is instructed to activate the second frequency domain resource, the first frequency domain resource is replaced by the second frequency domain resource. Such as BWP1 switch to BWP2. Or when the UE is instructed to activate the second frequency domain resource, the first frequency domain resource and the second frequency domain resource are activated simultaneously.

When the UE operates in the first frequency domain resource and is instructed to activate the second frequency domain resource, and the first frequency domain resource and the second frequency domain resource belong to the same frequency domain resource group, then according to the power control parameter of the first frequency domain resource Determine the power control parameters of the second frequency domain resource.

The frequency domain resource group includes one or more frequency domain resource sharing power control parameters. The frequency domain resource group can be RRC (Radio Resource Control) configuration, or RRC configures multiple frequency domain resource groups and one or more of them are activated by MAC layer signaling, or RRC configures multiple frequency domain resource groups. And one or more of them are activated by physical layer signaling. Among them, the frequency domain resource group can also be called a power control frequency domain resource group.

For example, the UE supports 5 CCs, of which the first 2 CCs are configured as power control frequency domain parameter group 1, and the last 3 CCs are configured as power control frequency domain parameter group 2. RRC signaling configures the above parameters. Or the RRC signaling is configured with the above parameters, and one or more of them are selected by the MAC layer signaling or the physical layer signaling as the frequency domain resource group effective at the current moment.

After the second frequency domain resource is activated, before the second frequency domain resource sends uplink transmission, the RS indicated by the path loss measurement parameter of the uplink transmission of the second frequency domain resource is not received, or the time is insufficient to estimate the path loss. Quantity, the power control parameter of the second frequency domain resource is determined according to the power control parameter of the first frequency domain resource.

The power control parameter of the transmission of the second frequency domain resource is partially or completely determined according to the power control parameter of the first frequency domain resource corresponding to the transmission of the reference signal resource information of the second frequency domain resource.

Wherein, determining the power control parameter of the transmission of the second frequency domain resource according to the power control parameter of the transmission of the first frequency domain resource may include: determining the second frequency domain resource according to the path loss measurement parameter of the power control parameter of the first frequency domain resource. The path loss measurement parameters of the transmitted power control parameters.

Alternatively, determining the power control parameter for the transmission of the second frequency domain resource according to the power control parameter for the transmission of the first frequency domain resource may include: determining the second frequency domain according to the open loop power control parameter of the power control parameter for the first frequency domain resource. Open-loop power control parameters of power control parameters for resource transmission.

Alternatively, determining the power control parameter for the transmission of the second frequency domain resource according to the power control parameter for the transmission of the first frequency domain resource may include: determining the second frequency domain resource according to the closed loop power control parameter of the power control parameter for the first frequency domain resource. The closed-loop power control parameters of the transmitted power control parameters. The closed-loop power control parameter includes at least one of the following: a closed-loop power control number, and a closed-loop power control adjustment amount corresponding to the closed-loop power control number.

Among them, the open-loop power control parameter, the closed-loop power control parameter, and the path loss measurement parameter of the power control parameter of the second frequency domain resource can be independently selected from the corresponding parameters in the power control parameter of the first frequency domain resource, or use the second Corresponding parameter of the power control parameter of the frequency domain resource. For example, the power control parameters of the second frequency domain resource may use only some of the parameters in the power control parameters of the first frequency domain resource. For another example, only the path loss measurement parameters in the power control parameters of the first frequency domain resource are used. The path loss measurement parameter among the power control parameters of the second frequency domain resource, and the remaining power control parameters are used for the second frequency domain resource.

Example: When the first frequency domain resource BWP1 is switched to the second frequency domain resource BWP2, even if RS for road loss measurement is independently configured for BWP2, if the PUSCH of BWP2 is scheduled on BWP1, it will be switched between BWP2 and PUSCH transmission It is likely that it is too late to send the corresponding RS for BWP2 for the path loss measurement, that is to say that the path loss estimation cannot be completed, so it is reasonable that the path loss measurement parameters of BWP1 are used for BWP2.

The path loss measurement parameter of the power control parameter of the first frequency domain resource is used to determine the path loss measurement parameter of the power control parameter of the second frequency domain resource transmission, until the RS of the path loss measurement configured for the transmission of the second frequency domain resource. send.

Alternatively, the path loss measurement parameter of the power control parameter of the first frequency domain resource is used to determine the path loss measurement parameter of the power control parameter of the second frequency domain resource transmission, until the path loss measurement configured for the transmission of the second frequency domain resource RS is transmitted, and the path loss of the RS is measured by the UE.

Optionally, when the number of path loss measurement parameters in the power control parameters of the first frequency domain resource is more than 1, the transmission loss of the second frequency domain resource is determined according to the path loss measurement parameters of the power control parameters of the first frequency domain resource. When the path loss measurement parameter of the power control parameter is used, the path loss measurement parameter of the power control parameter of the first frequency domain resource includes one of the following:

A path loss measurement parameter corresponding to the latest transmit power of the PUSCH transmitted in the first frequency domain resource;

The path loss measurement parameter corresponding to the transmission power of the latest PUCCH transmitted in the first frequency domain resource;

The path loss measurement parameter corresponding to the recent spatial relationship of the PUCCH activated in the first frequency domain resource;

The path loss measurement parameter corresponding to the spatial relationship of the PUCCH with the smallest resource number activated by the first frequency domain resource;

The path loss measurement parameter with the smallest number in the power control information of the PUSCH configured by the first frequency domain resource;

The path loss measurement parameter in the association with the smallest SRI and PUSCH power control association number in the PUSCH power control information of the first frequency domain resource configuration;

The minimum path loss value in the SSB and / or CSI-RS for path loss measurement configured by the first frequency domain resource.

For example, there are K1 path loss measurement parameters configured for PUSCH transmission of the first frequency domain resource, and the numbers k are 0 to K1-1, where K1 = 4. Then, the open loop power control parameter with the smallest number in the power control information of the PUSCH configured by the first frequency domain resource refers to a path loss measurement parameter with a number k of 0.

For another example, there are K1 open-loop power control parameters configured for PUSCH transmission of the first frequency domain resource, and the number k ranges from 0 to K1-1, where K1 = 4. And configure at least one association between SRI and path loss measurement parameters, assuming two associations, SRI0 is associated with k = 0, the corresponding association number is 0, SRI1 is associated with k = 3, and the corresponding association number is 1. Then the path loss measurement parameter in the association with the smallest correlation number between SRI and PUSCH power control in the PUSCH power control information of the first frequency domain resource configuration refers to the path loss measurement of j = 0 indicated in the association between SRI0 and j = 0. parameter.

The path loss value obtained from the measurement parameters of the first frequency domain resource configuration may be used as a path loss term in the calculation of the transmission power of the second frequency domain resource.

The minimum path loss value in the SSB and / or CSI-RS used for path loss measurement configured by the first frequency domain resource refers to selecting the smallest path loss value among the RSs for which the UE monitors the path loss information to use as the second frequency. The path loss value in the power control parameter of the domain resource.

Optionally, the power control parameter associated with the transmission of the first frequency domain resource includes one of the following:

The reference signal resource information associated with the physical downlink control channel PDCCH of the first frequency domain resource including scheduling signaling for transmission of the second frequency domain resource;

The reference signal resource information associated with the physical downlink control channel PDCCH of the first frequency domain resource including signaling for activating the second frequency domain resource;

Reference signal resource information associated with media access control signaling of the first frequency domain resource including signaling of activating the second frequency domain resource.

Optionally, an average value of at least one path loss value in the SSB and / or CSI-RS configured for path loss measurement of the first frequency domain resource that is greater than a predetermined threshold is used as a power control parameter in the second frequency domain resource. Road loss value.

Optionally, the maximum path loss value of at least one path loss value in the SSB and / or CSI-RS for path loss measurement that is greater than a predetermined threshold in the first frequency domain resource configuration is used as the second frequency domain resource power control parameter The road loss value in. The predetermined threshold is a value defined in advance, or a value configured by a base station.

Optionally, the open-loop power control parameter of the power control parameter of the first frequency-domain resource is used to determine the open-loop power control parameter of the power control parameter of the transmission of the second frequency-domain resource until it is configured for the transmission of the second frequency-domain resource. RS measurement of the path loss.

Alternatively, the open loop power control parameter of the power control parameter of the first frequency domain resource is used to determine the open loop power control parameter of the power control parameter of the transmission of the second frequency domain resource, until the path configured for the transmission of the second frequency domain resource is reached. The RS for loss measurement is transmitted, and the path loss amount of the RS is measured by the UE.

Optionally, when the number of open-loop power control parameters in the power control parameters of the first frequency domain resource is more than 1, the transmission of the second frequency domain resource is determined according to the path loss measurement parameter of the power control parameters of the first frequency domain resource. When the open-loop power control parameter of the power control parameter of the first open-loop power control parameter of the first frequency domain resource includes one of the following:

The open-loop power control parameter corresponding to the latest transmit power of the PUSCH transmitted in the first frequency domain resource;

The open-loop power control parameter corresponding to the latest transmit power of the PUCCH transmitted in the first frequency domain resource;

The open-loop power control parameter corresponding to the recent spatial relationship of the PUCCH activated in the first frequency domain resource;

The open-loop power control parameter corresponding to the spatial relationship of the PUCCH with the smallest resource number activated by the first frequency domain resource;

The open loop power control parameter with the smallest number in the power control information of the PUSCH configured by the first frequency domain resource;

The open-loop power control parameter in the association with the smallest SRI and PUSCH power control association number in the PUSCH power control information of the first frequency domain resource configuration;

For example, there are J1 open loop power control parameters configured for PUSCH transmission of the first frequency domain resource, and the numbers are 0 to J1-1. Then, the open loop power control parameter with the smallest number in the power control information of the PUSCH configured by the first frequency domain resource refers to the open loop power control parameter with the number 0.

For example, there are J1 open-loop power control parameters configured for PUSCH transmission of the first frequency domain resource, and the number j takes values from 0 to J1-1, where J1 = 8. And configure at least one association between SRI and open-loop power control parameters. It is assumed that there are two associations, SRI0 is associated with j = 0, the corresponding association number is 0, SRI1 is associated with j = 3, and the corresponding association number is 1.
