Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

First, the SRS will be described below.

SRS can be used for uplink channel information acquisition, downlink channel information acquisition and uplink beam management. The new air interface (New Radio, NR) manages and configures SRS in the form of SRS resource set. According to different purposes, the network device may configure multiple SRS resource sets for the terminal device, and each SRS resource set includes one or more SRS resources.

Wherein, each SRS resource includes 1, 2 or 4 ports. The configuration information of each SRS resource set contains a usage indication, which can be used for uplink beam management (beamManagement), codebook-based uplink channel information acquisition (codebook), and uplink channel information acquisition for non-codebook uplink transmission schemes (nonCodebook) and downlink channel information acquisition based on SRS antenna switching (antennaswitching).

It should be noted that the above SRS can be used for codebook transmission or non-codebook transmission.

The codebook transmission will be described below.

The codebook-based transmission scheme is a multi-antenna transmission technology in which a precoding matrix for uplink transmission is determined based on a fixed codebook. In the NR system, the codebook-based uplink transmission includes steps S101-S104:

S101. The terminal device sends to the network device an SRS for acquiring channel state information (Channel State Information, CSI) for uplink transmission based on a codebook.

S102, the network device performs uplink channel detection according to the SRS sent by the terminal device, performs resource scheduling on the terminal device, determines the SRS resource corresponding to the uplink transmission and the modulation and coding strategy (Modulation and Coding Scheme, MCS) level of the uplink transmission, and notifies the terminal equipment. Wherein, the SRS resource corresponding to the uplink transmission is indicated to the terminal device through the SRI.

S103. The terminal device modulates and codes the data according to the MCS indicated by the network device, and uses the indicated SRI, codebook indication information (Transmitted Precoding Matrix Indicator) TPMI and the number of transmission layers to determine the precoding matrix and transmission used for data transmission The number of layers, and then precoding and sending the data. Wherein, the demodulation pilot signal of the PUSCH and the data of the PUSCH adopt the same precoding manner.

S104. The network device estimates the uplink channel according to the demodulation pilot channel, and performs data detection.

It should be noted that, before R16, the NR system allowed terminal devices to configure at most one SRS resource set for CSI acquisition based on codebook uplink transmission. In this SRS resource set, a maximum of two SRS resources can be configured, and two SRS resources can be configured. Contains the same number of SRS antenna ports. Since the enhancement of PUSCH was introduced in R17, starting from R17, the NR system allows terminal devices to configure up to two SRS resource sets for uplink CSI acquisition based on the codebook, and does not specify the resources that can be included in the above two resource sets. Whether the number of resources is the same is limited. The network device can indicate the SRS resource corresponding to the PUSCH to the terminal device through the SRI field in the DCI, so as to assist the terminal device in determining the antenna used for PUSCH transmission, analog beamforming, etc. according to the selected SRS resource. Since the number of SRS resources configured for different uplink transmission schemes may be different, determining the number of bits corresponding to the SRI based on the uplink transmission scheme can reduce the overhead of the SRI. Therefore, the size of the SRI information used to indicate the SRS resource corresponding to the PUSCH in the uplink scheduling information depends on the number of SRS resources configured for the uplink transmission mode corresponding to the PUSCH. When only one SRS resource is configured for the SRS resource set used by the terminal device for codebook transmission, the PUSCH for the uplink transmission corresponds to the SRS resource, and there is no SRI information field in the uplink scheduling information.

The non-codebook transmission will be described below.

The difference between non-codebook transmission and codebook transmission is that the precoding of non-codebook transmission is no longer limited to a limited candidate set based on a fixed codebook, and the terminal device determines the uplink precoding matrix based on channel reciprocity. If the channel reciprocity is good enough, the terminal device can obtain better uplink precoding, compared with codebook transmission, it can save the overhead of precoding indication and obtain better performance at the same time.

In the NR system, the uplink transmission based on the non-codebook includes steps S201-S204:

S201. The terminal device measures a downlink reference signal, obtains a candidate uplink precoding matrix, uses the uplink precoding matrix to precode an SRS for non-codebook uplink transmission, and then sends the SRS to the network device.

S202. The network device performs uplink channel detection according to the SRS sent by the terminal device, performs resource scheduling on the terminal device, determines the SRS resources corresponding to the uplink transmission and the MCS level of the uplink transmission, etc., and notifies the terminal device. The SRS resource corresponding to the uplink transmission is indicated to the terminal device through the SRI.

S203. The terminal device modulates and codes the data according to the MCS sent by the network device, and uses the SRI to determine data precoding and the number of transmission layers, and then sends the data after precoding the data. The PUSCH demodulation pilot under the non-codebook uplink transmission scheme adopts the same precoding method as the PUSCH data.

S204. The network device estimates the uplink channel according to the demodulated pilot signal, and performs data detection.

It should be noted that, before R16, for non-codebook uplink transmission, the network device can configure one SRS resource set for uplink CSI acquisition for the terminal device, including 1-4 SRS resources, and each SRS resource includes 1 SRS ports. The SRI may indicate one or more SRS resources for determining PUSCH precoding. The number of SRS resources indicated by the SRI is the number of streams transmitted by the PUSCH, and the transmission layer of the PUSCH is in one-to-one correspondence with the SRS resources indicated by the SRI.

The uplink power control and the uplink power control indication are described below.

It should be understood that the uplink power control mainly includes an open-loop power control part, a closed-loop power control part and other adjustments. Wherein, the open-loop parameters of the PUSCH power control mainly include P0 and alpha values. PL is path loss estimation, and PL is estimated through a downlink reference signal. Alpha is a partial path loss compensation factor, and its value ranges from 0 to 1. Closed-loop power control, dynamically indicated by DCI. Wherein, the open-loop parameters P0 and alpha of the PUSCH power control are configured in pairs, which is called P0-PUSCH-AlphaSet.

For the configuration of uplink power control, SRI-PUSCH-PowerControlId is obtained from the SRI field in DCI. When DCI0-1 and DCI0-2 perform PUSCH scheduling, if there is an SRI field, a unique SRI-PUSCH-PowerControlId can be obtained A unique PUSCH-PathlossReferenceRS-Id and P0-PUSCH-AlphaSetId can be obtained according to the value of the SRI-PUSCH-PowerControlId. In R16 and before, if the SRI field does not exist, P0 and alpha take the values of P0 and alpha in the first P0-PUSCH-AlphaSet. The path loss is estimated based on the RS resource corresponding to the pusch-PathlossReferenceRS-Id being 0.

The enhancement of the P0 value will be described below.

In R16, the uplink PUSCH is enhanced for Ultra-reliable and Low Latency Communications (URLLC) transmission. When there is a conflict between the transmission resources of Enhanced Mobile Broadband (eMBB) PUSCH and URLLC PUSCH, eMBB PUSCH transmission can be canceled, or the URLLC PUSCH transmission power can be adjusted to improve the received SNR of URLLC PUSCH, and then Ensure the reliability of URLLC PUSCH transmission.

It should be noted that the purpose of power control in the above scenarios is different from that of traditional power control. It has the characteristics of suddenness, wide range of changes, and no continuity. Therefore, further adjustments have been made on the existing power control mechanism. Specifically, different open-loop power parameters may be set, and signaling is used to indicate which parameter is used for power calculation. By adopting the method of updating the open-loop power parameters, compared with the closed-loop power control, there is no accumulation problem of multiple transmissions, and the same power control effect can be achieved.

If the radio resource control (Radio Resource Control, RRC) is not configured with a power control parameter set list (p0-PUSCH-SetList), then there is no open loop power control parameter (Open loop power control, OLPC) field in the DCI. If RRC configures p0-PUSCH-SetList, the OLPC field is 1 bit or 2 bits. When there is an SRI field in the DCI, the OLPC field is 1 bit, and when there is no SRI field in the DCI, the OLPC field is configured by a high layer, for example, it can be 1 or 2 bits.

Wherein, p0-PUSCH-SetList includes at most two p0 values.

When the SRI field exists, the OLPC field in the DCI occupies 1 bit, which can indicate a value of 0 or 1. Wherein, when the indicated value is 1, the P0 value is indexed to a P0 value in p0-PUSCH-SetList according to the SRI value in the SRI domain;

When the SRI field does not exist, the OLPC field occupies 1 or 2 bits. When OLPC indicates 0 or 00, take the first P0 value in p0-AlphaSets. When the OLPC indication is 1 or 01, it indicates the first value of the P0-PUSCH-Set in the smallest p0-PUSCH-SetID; when the OLPC indication is 10, it indicates the P0-PUSCH in the smallest p0-PUSCH-SetID - The second value of the Set.

At present, the processing for OLPC is the situation that all SRI domains exist or none exist. However, if the number of SRS resources contained in two SRS resource sets is different and the number of SRS resources contained in one SRS resource set is 1, according to the existing conclusions, the SRS resource set will not have an SRI field in the DCI. That is, there are situations where one SRS resource set has an SRI field in the DCI, and the other SRS resource set has no SRI field in the DCI.

In the related technology, in the R17 meeting progress, if the number of SRS resources contained in two SRS resource sets is different and the number of SRS resources contained in one of the SRS resource sets is 1, the SRS resource set with multiple resources exists in the DCI The SRS resource indicator (SRI) domain, the SRS resource set with the number of resources being 1 will not have the SRI domain in the DCI. Therefore, there may be an SRS resource set with an SRI field in the DCI, and another SRS resource set without the SRI field in the DCI.

However, if the SRS resource set has an SRI field in the DCI, it indicates that the size of the power control parameter field in the DCI is determined based on the existence of the SRI field. If the SRS resource set does not have an SRI field in the DCI, it indicates the power control parameter. The size of the domain in the DCI is determined by the indication information configured by the network device and configured through high-layer signaling. Therefore, when there are multiple SRS resource sets, the power control parameters during PUSCH transmission cannot be determined.

In order to solve the above problems, the embodiments of the present application provide a communication method and device. When a terminal device receives DCI to schedule PUSCH transmission, it can determine power control parameters during PUSCH transmission based on DCI and configuration information. In this way, even if there are multiple SRS resource sets, and one SRS resource set contains one resource, and the other SRS resource set contains multiple resources, the terminal device can still determine the function of PUSCH transmission through the first DCI and configuration information. control parameters.

The technical solutions of the embodiments of the present application will be described in detail below using specific embodiments by taking terminal devices and network devices as examples. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

FIG. 2 is a signaling interaction diagram of a communication method provided by an embodiment of the present application. The executors of the embodiment of the present application are the terminal device and the network device, and relate to the process of how the terminal device determines the power control parameters during PUSCH transmission. As shown in Figure 2, the method includes:

S301. The network device sends the first DCI to the terminal device, where the first DCI is used to schedule transmission of a physical uplink shared channel PUSCH.

It should be understood that this embodiment of the present application does not limit how to perform PUSCH transmission. In some embodiments, the first DCI may indicate that PUSCH transmission is based on SRS resources of one SRS resource set, that is, single TPR transmission. Or, the first DCI may indicate that the transmission of the PUSCH is based on the resource of each SRS resource set in the multiple SRS resource sets, that is, multiple TPR transmission.

Exemplarily, if the first DCI indicates that the PUSCH is transmitted based on the resources of the first SRS resource set and the second SRS resource set, the transmission of the PUSCH is repeated transmission, and each repeated transmission of the PUSCH is based on the first SRS resource set or the second SRS resource set. The SRS resources of one resource set in the two SRS resource sets.

It should be understood that the repeated transmission means that the same PUSCH is repeatedly transmitted at different times through the SRS resources of the first SRS resource set and the SRS resources of the second SRS resource set.

It should be noted that the transmission of the PUSCH involved in the embodiment of the present application may be codebook transmission or non-codebook transmission, which is not limited in the embodiment of the present application.

S302. The terminal device determines a power control parameter during PUSCH transmission according to the first DCI and configuration information.

In this application, after receiving the first DCI, the terminal device may determine the power control parameters during PUSCH transmission according to the first DCI and configuration information, so as to perform PUSCH transmission using the power control parameters during PUSCH transmission.

In some embodiments, the power control parameter during PUSCH transmission is an open-loop receiving end power target value configured independently of the open-loop parameter set, such as a P0 value.

The open-loop parameter set configuration includes an open-loop receiving end power target value and a partial path loss compensation factor, and the power control parameter during PUSCH transmission is used by the network device to indicate values different from the open-loop parameter values in the open-loop parameter set configuration.

In some embodiments, the configuration information includes at least one SRS resource set.

At least one SRS resource set may include one SRS resource set, or may include two resource sets, which is not limited in this embodiment of the present application. In some embodiments, if two resource sets are included, the number of resources in the two resource sets may be the same, each including one resource or multiple resources. In some other embodiments, if two resource sets are included, the number of resources in the two resource sets may also be different, one resource set may include multiple resources, and the other resource set may include one resource.

Exemplarily, the at least one SRS resource set includes a first SRS resource set and/or a second SRS resource set. The first SRS resource set may include multiple SRS resources, and the second SRS resource set may include one SRS resource.

Correspondingly, for the first SRS resource set, there is a first indication field in the first DCI, and the first indication field is used to indicate the SRS resource selected by the PUSCH when transmitting based on the SRS resources of the first SRS resource set. For the second SRS resource set, there is no SRS resource used to indicate the SRS resource selected by the PUSCH when the SRS resource of the second SRS resource set is transmitted based on the DCI.

It should be noted that, the above-mentioned first indication field may specifically be an SRI field.

In some embodiments, the configuration information further includes first indication information, the first indication information is used for the terminal device to obtain the size of the power control parameter field in the DCI during PUSCH transmission, and the first indication information is configured by high-layer signaling.

The embodiment of the present application does not limit the size of the power control parameter field indicated by the first indication information in the first DCI. For example, the power control parameter field indicated by the first indication information can be configured as 1 bit or 2 bits. .

It should be noted that the configuration information in the embodiment of the present application may include the first indication information, or may not include the first indication information, which is not limited in the embodiment of the present application.

In this embodiment of the present application, if the terminal device has a power control parameter field in the first DCI, the terminal device determines the size of the power control parameter field in the DCI according to at least one SRS resource set and/or the first indication information, and the power control The parameter field is used to determine the power target value of the open-loop receiving end during PUSCH transmission.

In some embodiments, the configuration information further includes second indication information, and the second indication information is used to indicate at least one set of power control parameter set lists configured by the network device.

Wherein, at least one set of power control parameter set lists includes a first power control parameter set list and/or a second power control parameter set list, the first power control parameter set list corresponds to the first SRS resource set, and the second power control parameter set list The list corresponds to the second set of SRS resources.

Wherein, each power control parameter set list includes one or more power control parameter sets, and each power control parameter set includes at most two values of the power control parameters.

It should be noted that the above power control parameter set list may be, for example, P0-PUSCH-Set-r16_list, which is used to enhance the P0 value of URLLC.

In some embodiments, the configuration information further includes third indication information, the configuration information further includes third indication information, and the third indication information is used to indicate the number of power control parameter domains.

In some embodiments, the terminal device may report fourth information to the network device, where the fourth information is used to indicate whether the terminal device supports two power control parameter domains. The number of power control parameter domains can be determined through the fourth information.

Exemplarily, if the terminal device does not support two power control parameter domains, only one power control parameter domain is configured. If the terminal device supports two power control parameter domains, the configured power control parameter domain includes a first power control parameter domain corresponding to the first SRS resource set and a second power control parameter domain corresponding to the second SRS resource set.

Wherein, the size of the first power control parameter field in the DCI is determined according to the presence of the first indication field indicated in the first DCI, and the size of the second power control parameter field in the DCI is used to indicate that the PUSCH is based on the presence of the second power control parameter field in the DCI. The SRS resources selected during the transmission of the SRS resources of the two SRS resource sets are jointly determined by the first indication information.

It should be noted that the configuration information in this embodiment of the present application may be configured by a network device as a terminal device.

How to determine the size of the power control parameter domain in the DCI will be described below.

In some embodiments, if the PUSCH is transmitted according to resources in the first SRS resource set and/or resources in the second SRS resource set, the terminal device may determine the size of the power control parameter field in the DCI according to the existence of the first indication field .

It should be understood that when determining the size of the power control parameter field in the DCI according to the existence of the first indication field, the configuration information may or may not include the first indication information, which is not done in this embodiment of the present application. limit.

It should be noted that, in this embodiment of the present application, there is no limitation on the size of the power control parameter field in the DCI when the first indication field exists, for example, it may be 1 bit.

Correspondingly, if the value of the power control parameter field is 1, the value of the first power control parameter is determined according to the first power control parameter set list and the value of the first indication field, and/or, the value of the second power control parameter The value is the first value of the power control parameter corresponding to the smallest identifier in the second power control parameter set list.

In some other embodiments, if the PUSCH is transmitted according to the resources in the first SRS resource set and/or the resources in the second SRS resource set, the size of the power control parameter field in the DCI is used to indicate that the PUSCH is not present in the DCI. The SRS resources selected during the SRS resource transmission based on the second SRS resource set and the first indication information are jointly determined.

Correspondingly, if the value of the power control parameter field is not 0, the value of the first power control parameter is determined according to the first power control parameter set list and the value of the first indication field.

Exemplarily, the value of the power control parameter field is not 0, which may include that the value of the power control parameter field is not 0 when the power control parameter field occupies 1 bit in the DCI, and the power control parameter field occupies 2 bits in the DCI. The value of the bit time power control parameter field is not 00.

Correspondingly, if the value of the power control parameter field is 01, the value of the second power control parameter is the first value of the power control parameter corresponding to the smallest identifier in the second power control parameter set list; if the power control parameter field is 10, then the value of the second power control parameter is the second value of the power control parameter corresponding to the smallest identifier in the second power control parameter set list.

Since there is no SRS resource in the DCI used to indicate the SRS resource selected by the PUSCH when transmitting the SRS resource based on the second SRS resource set, the terminal device can obtain the size of the power control parameter field indicated by the first indication information in the DCI, for example, 1 bit or 2 bits.

It should be noted that when there is the first indication information and resources in the first SRS resource set and/or resources in the second SRS resource set are used for transmission, it can be used to indicate that the PUSCH is based on the second SRS resource based on the absence of DCI. The selected SRS resource and the first indication information are jointly determined when the set of SRS resources are transmitted.

It should be understood that the value of the above power control parameter field may be indicated by the network device.

It should be understood that the value of the first power control parameter is determined by indexing from the first power control parameter set list through the value of the SRS resource indication field.

It should be understood that the foregoing minimum identifier is the smallest identifier of the power control parameter set in the second power control parameter set list.

In some embodiments, the terminal device will determine the size of the power control parameter field in the DCI according to the existence of the first indication field, and, according to the absence of the DCI, is used to indicate that the PUSCH is transmitted based on the SRS resource of the second SRS resource set The selected SRS resource is compared with the size of the power control parameter field in the DCI jointly determined by the first indication information. The larger or smaller value of the size of the power control parameter field in the DCI determined after the comparison is used as the final value of the size of the power control parameter field in the DCI.

In the communication method and device provided in the embodiments of the present application, the terminal equipment first receives the first DCI, and the first DCI is used to schedule transmission of the physical uplink shared channel PUSCH. Subsequently, the terminal device determines power control parameters during PUSCH transmission according to the first DCI and configuration information. Wherein, the configuration information includes at least one SRS resource set. In this way, even if there are multiple SRS resource sets, and one SRS resource set contains one resource, and the other SRS resource set contains multiple resources, the terminal device can still determine the function of PUSCH transmission through the first DCI and configuration information. control parameters.

FIG. 3 is a signaling interaction diagram of another communication method provided by an embodiment of the present application.

As shown in Figure 3, the method includes:

If the value of the power control parameter field is 1, the terminal device determines the value of the first power control parameter according to the first power control parameter set list and the The first value of the corresponding power control parameter determines the value of the second power control parameter.

Exemplarily, the value of the first power control parameter is indexed and determined from the first power control parameter set list P0-PUSCH-Set-r16_list corresponding to the first SRS resource set through the value of the SRS resource indication field.

Exemplarily, the terminal device may first determine the second power control parameter set list P0-PUSCH-Set-r16_list corresponding to the second SRS resource set, and then obtain the P0-PUSCH-Set No. A value of P0 is used as the value of the second power control parameter.

S405. The terminal device performs repeated transmission of the PUSCH by using resources in the first SRS resource set and resources in the second SRS resource set according to the value of the first power control parameter, the value of the second power control parameter, and other channel parameters indicated by the DCI.

FIG. 4 is a signaling interaction diagram of another communication method provided by the embodiment of the present application. The executors of the embodiment of the present application are the terminal device and the network device, and relate to another manner of how the terminal device determines the power control parameter during PUSCH transmission during multi-TRP transmission.
