Description

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

This application claims priority from a Chinese patent application filed with the Chinese Patent Office on August 9, 2018, with application number 201810904645.6, the entire contents of which are incorporated herein by reference.

Technical field

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

Background technique

A new generation of wireless communication (NR, new radio) technology is under development. As a fifth generation mobile communication system, the technology needs to support an unprecedented number of different types of application scenarios. It also needs to support traditional frequency bands, new high frequency bands and beams Method, it brings great challenges to the 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, and transmission rate. In New Radio (NR), the uplink transmission 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). The uplink transmission can be scheduled by the base station in a periodic manner or dynamically. The user equipment (User Equipment, UE) can also decide to send a PRACH by 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. Due to the limitation of the UE's capabilities, the UE cannot use the corresponding beams for simultaneous transmission according to the scheduling information of each uplink transmission, then the UE may change some of the uplink transmission beams. Because there is a corresponding relationship between the beam and power, the corresponding transmission power will also change after the beam is changed.

In the related art, when multiple uplink transmissions need to be sent at the same time, for the problem that the corresponding power control parameter cannot be obtained for the uplink transmission after the beam is changed, no solution has been proposed in the related art.

detailed description

Hereinafter, the present disclosure will be described in detail with reference to the drawings and embodiments. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

It should be noted that the terms “first” and “second” in the description and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

In order to more clearly illustrate the technical solution involved in this embodiment, some technical terms are further explained below:

In a wireless communication system, in order to reduce the power consumption of a 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 general communication technology, the communication node 1 sends a reference signal, and the communication node 2 measures a path loss (PL, pathloss) from the node 1 to the 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-mentioned 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.

In Long Term Evolution (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 of the transmission power of the PUSCH of LTE, and as an example, each parameter affecting the power is described.

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

The open-loop part of the power for uplink transmission of PUSCH is determined by the target received power, 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; 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 transmission power control command, and uses the above formula to achieve the purpose of closed-loop control power; where i is the subframe number and ΔTF is the MCS-related power offset, which is the UE Maximum power limit.

The LTE cell-level target received power P0_nominal distinguishes between PUSCH (semi-static, dynamic, and message 3MSG3) and PUCCH, which correspond to different Block Error Rate (BLER, Error Ratio) requirements, respectively. 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). It is the UE's local closed-loop power adjustment for PUCCH. the amount.

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

In 5G technology, the power control of the uplink transmission is a Bandwidth Part (BWP) level, that is, for each BWP level of uplink transmission, the transmission power is determined separately.

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 require base station configuration, so the path loss measurement parameters exist independently of the open-loop power control parameters and the closed-loop power control parameters.

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

The above reference signal resources include at least one of the following: an uplink sounding signal (Sounding Reference Signal, SRS), a channel state information reference signal (Channel State Information Reference Signal, CSI-RS), a secondary synchronization signal 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).

Example 1

A method for determining a power control parameter is provided in this embodiment. 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 process includes the following steps:

Step S102, acquiring airspace resource information of the first transmission and airspace resource information of the second transmission;

Step S104: Adjust at least part of the airspace resource information of the first transmission according to the following objects:

Airspace resource information for the second transmission, or

The set of airspace information resources associated with the first transmission and the airspace resource information associated with the second transmission;

Step S106: Determine at least part of the power control parameters of the first transmission according to the adjusted airspace resource information of the first transmission.

Through the above steps, during the process of sending the airspace resource information of the first transmission and the airspace resource information of the second transmission, the airspace resource information of the second transmission and the airspace resource information of the first transmission or the The set of airspace information resources is used to adjust the airspace resource information of the first transmission, and to obtain at least part of the power control parameters of the first transmission according to the adjusted airspace resource information of the first transmission. Therefore, this embodiment can solve the related technology When multiple uplink transmissions need to be sent at the same time, the problem is that the corresponding power parameter cannot be obtained for the uplink transmission after the beam is changed, so as to achieve the effect of obtaining the power control parameter of the uplink transmission after the beam is changed.

At the same time, the above steps can flexibly implement an optimal power control solution for different beam conflict scenarios.

Specifically, the above-mentioned airspace resource information of the first transmission includes at least one airspace resource information. The adjusted airspace resource information of the first transmission includes only the adjusted airspace resource information portion, and the unadjusted portion is still the original first transmission. Airspace resource information. For example, the first transmission is PUSCH, and the original airspace resource information of the first transmission includes 2 airspace resource information, where each airspace resource information is represented by an SRS resource, and the identifiers of the 2 airspace resource information are SRS-1, SRS- 2. The second transmission is PUCCH, and the airspace resource information of the second transmission includes 1 airspace resource information. The airspace resource information is represented by a spatial relationship and is recorded as a spatial relationship -1.

Assuming that the spatial relationship-1 can be transmitted at the same time as SRS-1, but cannot be transmitted at the same time as SRS-2, the spatial relationship-1 replaces SRS-2 to form the second airspace resource information for the first transmission. That is, the airspace resource information of the first transmission PUSCH includes two airspace resource information SRS-1 and SRS-2, one of which is adjusted to the spatial relationship -1, and the adjusted airspace resource information becomes the adjusted first transmission airspace after adjustment. Resource information. 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 above steps may be performed by a base station, a UE, etc., but are not limited thereto. In the specific implementation process, the base station and the UE can be named by various communication nodes such as NB (NodeB), gNB, TRP (transmitter receiver point), AP (access point), site, user, STA, relay, terminal, etc. instead. The base station may also refer to a network side, universal terrestrial radio access (UTRA), evolved UTRA (evolved universal terrestrial radio access, EUTRA), and the like.

The uplink transmission may be configured by the base station for the UE. Such transmission is generally scheduled periodically or semi-persistently. The uplink transmission may also be dynamically scheduled by the base station for the UE. In addition, the UE also uses uplink transmission for the HARQ ACK / NACK information received from the downlink transmission, which may be dynamically scheduled, or it may be periodically scheduled or semi-persistently scheduled resources.

Each uplink transmission has certain scheduling information, which is used to indicate the time domain, frequency domain, and air domain resource information occupied by the uplink transmission. The airspace resource information specifically indicates beam resources for uplink transmission.

To support the beam mode, optionally, the above-mentioned first transmission power control parameter includes at least one of the following: an open-loop power control parameter, a closed-loop power control parameter, and a path loss measurement parameter.

It should be further explained that the above-mentioned path loss measurement parameter is also referred to as the RS parameter of the path loss measurement. Each part of the power control parameters supports multiple configurations, that is, up to J open-loop power control parameters can be configured, and the number of each open-loop power control parameter is j; up to K path loss measurement parameters can be configured for each path loss. The number of the measurement parameter is k; the maximum number of closed-loop power control parameters can be configured, and the number of each closed-loop power control parameter is l; where j is an integer greater than 0 and less than or equal to J, and k is an integer greater than 0 and less than or equal to K. Integer, l is an integer greater than 0 and less than or equal to L, and J, K, and L are all integers greater than 0.

Specifically, the above open-loop power control parameters include at least one of the following: target received power and path loss factor; the above-mentioned path loss measurement parameters include at least one of the following: a reference signal resource type indication used for path loss measurement, Reference signal resource indication for loss measurement, processing rules for path loss values of two or more reference signals for path loss measurement; the above-mentioned closed-loop power control process parameters include at least one of the following: closed-loop power control process identification set, closed-loop power control Number of processes.

In order to further explain the method for controlling the power control of the uplink transmission of the UE according to the power control parameter in this embodiment, the following example is used for explanation (the power control parameter here defaults to 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 the PUSCH transmission of the UE.

The base station configures the PUSCH transmission mode for the UE, such as codebook-based transmission or 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.

For PUCCH transmission, there are similar methods for determining power control parameters. The difference from PUSCH is that the beam of the PUCCH is identified by the spatial relationship information, the base station configures the association of the spatial relationship information set of the PUCCH and the power control parameters, and the spatial relationship information transmitted by the PUCCH is indicated by the MAC CE, and the UE is instructed by the MAC CE The correlation between the spatial relationship information and the set of spatial relationship information of the PUCCH configured by the base station and the power control parameters determines the power control parameters of the PUCCH.

The spatial relationship between the reference signal resources of the PUSCH and the PUCCH is the airspace resource information in this embodiment. The airspace resource information uses reference signal resource information, such as SRS or SRI, or the spatial relationship indicates the transmission method, and the transmission method may include a beam

The airspace resource information of the first transmission and the airspace resource information of the second transmission belong to the same type A packet, where the type A packet includes at least one of the following: an antenna panel group, a panel group, and an antenna array group;

The airspace resource information of the first transmission and the airspace resource information of the second transmission belong to the same type B group, where the type B group includes at least one of the following: sub-antenna panel grouping, sub-panel grouping, and sub-antenna array grouping;

The first transmitted airspace resource information and the second transmitted airspace resource information belong to different type C packets, where the type C packet includes: an array packet.

The first transmitted airspace resource information is associated with the same closed loop power control as the second transmitted airspace resource information.

It should be further explained that, in the case of meeting the characteristics of grouping between the airspace resources of the first transmission and the airspace resources of the second transmission, the airspace resources of the first transmission and the airspace resources of the second transmission cannot be sent simultaneously; The characteristics of the grouping between the airspace resources of one transmission and the airspace resources of the second transmission are only a way to describe that the airspace resources of the first transmission and the airspace resources of the second transmission cannot be sent at the same time. The characteristics or conditions of the airspace resources and the airspace resources of the second transmission in a state where they cannot be transmitted simultaneously belong to the protection scope of the present disclosure.

The adjusted airspace resource information of the first transmission and the second transmission of airspace resource information belong to different type A packets, where the type A packet includes at least one of the following: antenna panel group, panel group, and antenna array group;

The adjusted airspace resource information of the first transmission and the airspace resource information of the second transmission belong to different type B packets, where the type B packet includes at least one of the following: sub-antenna panel grouping, sub-panel grouping, and sub-antenna array Group

The adjusted airspace resource information of the first transmission and the second transmitted airspace resource information belong to the same type C packet, where the type C packet includes: an array packet.

It should be further explained that, in a case where the grouping characteristics between the airspace resources of the first transmission and the airspace resources of the second transmission after the adjustment are met, between the airspace resources of the first transmission and the airspace resources of the second transmission after adjustment Can send at the same time; The above-mentioned adjusted grouping characteristics between the airspace resources of the first transmission and the second transmission of the airspace resources only describe that the adjusted airspace resources of the first transmission and the airspace resources of the second transmission can be transmitted simultaneously. In one mode, in the art, the characteristics or conditions of the airspace resources of the first transmission and the airspace resources of the second transmission that can be sent simultaneously belong to the protection scope of the present disclosure.

In addition, it is not limited to the first transmission and the second transmission in this embodiment.

At the same time, the power control parameter information obtained according to the first transmitted power control parameter may be determined in at least one of the following ways:

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

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

In addition, the closed-loop power control parameter in the power control parameter of the first transmission may also use the closed-loop power control corresponding to the mapping between the air-space resource information configured for the first transmission channel and the power control parameter using the air-space resource information of the first transmission. Parameter, at this time, the local closed loop power control value for the first transmission is cleared.

At the same time, through the above steps, in the case where the difference between the first transmission and the second transmission before and after the beam change is not large, the original power parameter can be used and the original closed-loop value is inherited; In the case of a large beam change, the PL uses the PL corresponding to the changed beam, and the remaining parameters use default values, and the closed-loop power control is reset.

In addition, for the cumulative closed-loop power adjustment, the first transmission may also use the accumulated value of the local closed-loop power adjustment.

For example, when the airspace resource information of the second transmission is SRI1, the airspace resource information of the first transmission is SRI2, the beam difference between SRI1 and SRI2 is small, or the difference between their respective channel measurement parameters is less than a predetermined threshold, the first transmission adjusts the airspace The resource information is SRI1, but the power control parameter of the first transmission may also use the power control parameter corresponding to the airspace resource information SRI2 before adjustment in the mapping relationship between the airspace resource information and the power control parameter configured for the first transmission channel.

In order to further describe the method for determining the power control parameter in this embodiment, the following further describes in specific embodiments:

Specific Example 1

FIG. 2 is a schematic diagram of a beam relationship between a first transmission and a second transmission according to a specific embodiment of the present disclosure; as shown in FIG. 2, the second transmission uses a beam 1 shown by SRS1. The UE does not support beam 2 and beam 1 transmission at the same time, and the UE does not support beam 1 and beam 2 transmission at the same time.

When multiple uplink transmissions have at least part of the time domain overlap, and their airspace resource information is not completely consistent, due to the capability of the UE, the UE cannot send some combined beams at the same time, that is, the UE cannot perform the airspace resource information based on each uplink transmission. When sending, the UE can perform processing in one of the following scenarios:

Option 1: Do not send all conflicting uplink transmissions.

That is, according to the processing method of scheme 1, neither the first transmission nor the second transmission with overlapping domains in FIG. 2 are sent.

The second solution is to send the uplink transmission with high priority and discard the uplink transmission with low priority.

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

Assume that the priority of the second transmission in FIG. 2 is high, and the second transmission is sent according to the processing manner of the scheme 2, and the first transmission is discarded.

The third solution is to send the uplink transmission with high priority according to the scheduling information, adjust the airspace resource information of low priority uplink transmission based on the airspace resource information of high priority uplink transmission, and send the uplink transmission of low priority.

Assuming that the second transmission in FIG. 2 has a higher priority, the second transmission is sent according to the scheduling information according to scheme three, and the airspace resource information of the first transmission is adjusted according to the airspace resource information of the second transmission, and then the adjusted airspace resource The message is transmitted first.

For the above solution three, 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 low priority uplink transmission is determined as follows.

In the third solution of the embodiment of the present invention, the first transmission of the airspace resource information is adjusted.

3 is a schematic diagram illustrating a beam relationship between an adjusted first transmission and a second transmission according to a specific embodiment of the present disclosure; as shown in FIG. 3, the UE can only send one beam. Because the priority of the second transmission is high, the first transmission One transmission is transmitted using the beam of the second transmission.

The airspace resource information of the second transmission is used as part of the airspace resource information of the first transmission. For example, the airspace resource information of the second transmission indicates SRS1, and the airspace resource information of the first transmission indicates SRS2 and SRS3. The UE can send beams represented by SRS2 and SRS3 at the same time, but cannot support beams of SRS1, SRS2, and SRS3 at the same time. Because the priority of the second transmission is high, the airspace resource information of the first transmission is adjusted according to the airspace resource information of the second transmission. Modify the first transmitted airspace resource information to SRS1 and SRS2, or SRS1 and SRS3. Optionally, the channels represented by SRS2 and SRS3 use better transmission quality, for example, the PL is lower, or the transmission power is lower.

Part of the airspace resource information of the second transmission is used as the airspace resource information of the first transmission. For example, the airspace resource information of the second transmission indicates SRS1 and SRS2, and the airspace resource information of the first transmission indicates SRS3. The UE can send the beams represented by SRS1 and SRS2 at the same time, but cannot support the beams of SRS1, SRS2, and SRS3. Because the priority of the second transmission is high, the airspace resource information of the first transmission is adjusted according to the airspace resource information of the second transmission. Modify the first transmitted airspace resource information to SRS1 or SRS2. Optionally, the channels represented by SRS1 and SRS2 use better transmission quality, such as lower PL, or lower transmission power.

Part of the airspace resource information of the second transmission is used as part of the airspace resource information of the first transmission. For example, the airspace resource information of the second transmission indicates SRS1 and SRS2, and the airspace resource information of the first transmission indicates SRS1 and SRS3. The UE can send beams represented by SRS1 and SRS3 at the same time, but cannot support beams of SRS1, SRS2, and SRS3 at the same time. Because the priority of the second transmission is high, the airspace resource information of the first transmission is adjusted according to the airspace resource information of the second transmission. Modify the first transmitted airspace resource information to SRS1 and SRS2.
