Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the related art, for downlink Transmission of an NR (New Radio) air interface mobile communication system (abbreviated as NR system), currently, only a Single-Transmission Reception Point (Single-TRP) Transmission scenario is generally considered, as shown in fig. 1, a UE (User Equipment) feeds back Uplink Control Information for downlink Transmission of a Single-TRP, such as HARQ (Hybrid Automatic Repeat Request ) Information and CSI (Channel State Information) on a PUCCH (Physical Uplink Control Channel) resource indicated by a network device, where the HARQ Information includes ACK (Acknowledgement) Information or NACK (Negative Acknowledgement) Information. In addition, the network device may further configure space-related information (also referred to as beam information) transmitted by a PUCCH and used for carrying HARQ information and CSI, specifically, configure a space-related information set corresponding to the PUCCH Resource through an RRC (Radio Resource Control) signaling, and indicate specific space-related information used for carrying the HARQ information and the CSI in the space-related information set through identification information indicated by a Media Access Control (MAC) CE (Control Element) signaling.

However, in the NR mobile communication system, both low-frequency and high-frequency downlink transmissions support a Multi-Transmission Reception Point (Multi-TRP) Transmission scenario, and when a plurality of TRPs perform downlink transmissions simultaneously, as shown in fig. 2 and 3, TRP1 and TRP2 perform downlink transmissions simultaneously, and when the UE simultaneously feeds back HARQ feedback information and CSI corresponding to a plurality of downlinks, there may be a case where a plurality of PUCCH resources collide and cannot be transmitted simultaneously. That is to say, when the UE does not support multiple PUCCH transmission functions, the spatial correlation information corresponding to the PUCCH needs to be configured and indicated, so as to improve the accuracy of the spatial correlation information transmitted by the PUCCH and improve uplink transmission performance.

User Equipment (UE), which may also be referred to as Terminal Equipment (Mobile Terminal), Mobile User Equipment (ms), and the like, may communicate with one or more core networks through a Radio Access Network (RAN, Radio Access Network, for example), and the UE may be Terminal Equipment, such as a Mobile phone (or a "cellular" phone) and a computer having the Terminal Equipment, such as a portable, pocket, handheld, computer-embedded, or vehicle-mounted Mobile device, which exchange language and/or data with the Radio Access Network; and the base station may be a 5G base station (gNB), which may have a plurality of localized or distributed TRPs.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 4, an embodiment of the present invention provides an information transmission method, which is applied to a terminal device.

The method comprises the following steps:

s101: and determining a second PUCCH resource under the condition that at least two first physical uplink control channel PUCCH resources collide.

Optionally, the at least two first PUCCH resources may be a time domain collision, a frequency domain collision, or both a time domain collision and a frequency domain collision, where the time domain collision may refer to that the at least two first PUCCH resources occupy 1 same symbol, and the frequency domain collision may refer to that the at least two first PUCCH resources occupy 1 same subcarrier; the second PUCCH resource may specifically be a PUCCH resource that is not in conflict with the at least two first PUCCH resources and is pre-configured by the network device.

Optionally, the at least two first PUCCH resources correspond to at least two downlink transmission channels of the same type, and downlink transmission channels corresponding to any two first PUCCH resources in the at least two first PUCCH resources are different.

It is to be understood that the at least two Downlink transport channels belonging to the same type may be a physical Downlink Shared channel pdsch (physical Downlink Shared channel).

Optionally, the at least two first PUCCH resources correspond to the at least two transmission/reception points TRP.

Optionally, there is a one-to-one correspondence between the at least two first PUCCH resources and the at least two TPRs; or a many-to-one correspondence relationship between the at least two first PUCCH resources and the at least two TPRs.

It can be understood that, multiple paths of downlink transmissions are performed through multiple TRPs, on one hand, corresponding first PUCCH resources may be configured for each TRP, so that uplink control information is transmitted through the corresponding first PUCCH resources for each path of downlink transmissions; alternatively, a plurality of first PUCCH resources may be configured for each TRP, that is, multiplexed downlink transmission may be performed through the same TRP.

S103: and determining target space-related information corresponding to the second PUCCH resource.

S105: and transmitting Uplink Control Information (UCI) based on the target space related information, wherein the UCI is carried on the second PUCCH resource and comprises all or part of the UCI carried by the at least two first PUCCH resources.

It can be understood that, in the embodiment of the present invention, when at least two first PUCCH resources collide and uplink control information carried by each first PUCCH resource cannot be simultaneously transmitted, all or part of UCI originally required to be carried on the at least two first PUCCH resources is uplink-transmitted through the second PUCCH resource, and uplink control information corresponding to the at least two first PUCCH resources can be uplink-fed in time, so as to improve uplink transmission performance.

Optionally, in this embodiment of the present invention, the uplink control information UCI includes at least one of HARQ feedback information and CSI.

Optionally, in the embodiment of the present invention, the target space-related information may be determined in different manners, so that the terminal device realizes simultaneous transmission of uplink control information corresponding to multiple downlink transmissions through the target space-related information.

In a specific embodiment of the present invention, the target spatial correlation information is spatial correlation information corresponding to at least one target first PUCCH resource of the at least two first PUCCH resources.

It may be appreciated that, in determining the target spatial correlation information corresponding to the second PUCCH resource, spatial correlation information corresponding to at least one target first PUCCH resource of the at least two first PUCCH resources may be multiplexed on the basis of the at least two first PUCCH resources.

Optionally, the method for information transmission according to the embodiment of the present invention may further include:

receiving Radio Resource Control (RRC) signaling, wherein the RRC signaling is used for indicating a first space-related information set, and the first space-related information set corresponds to a second PUCCH resource.

It can be understood that the corresponding first spatial correlation information set is configured independently for the second PUCCH resource through RRC signaling; the RRC signaling and the RRC signaling indicating the spatial correlation information set configured for the first PUCCH resource may be received together or separately, and the first spatial correlation information set corresponding to the second PUCCH resource can be obtained before step S103.

Optionally, the first spatial correlation information set includes at least one piece of spatial correlation information corresponding to the second PUCCH resource.

Further, in the case that a corresponding spatial correlation information set is configured independently for the second PUCCH resource, the step S103 may specifically be performed as:

receiving a media access control (MAC CE) signaling, wherein the MAC CE signaling is used for indicating identification information of space related information corresponding to at least one target first Physical Uplink Control Channel (PUCCH) resource;

and determining the target space related information as the space related information corresponding to the identification information in the first space related information set.

It can be understood that, in the case that the first spatial correlation information set is configured independently for the second PUCCH resource, the target spatial correlation information may be obtained in the first spatial correlation information set by multiplexing an indication of spatial correlation information corresponding to at least one target first PUCCH resource of the at least two first PUCCH resources; the identification information indicated by the MAC CE signaling may be a uniquely identifiable identification such as a label or a number of the spatial correlation information.

It should be noted that, in order to multiplex the identifier information indicated by the MAC CE signaling corresponding to at least one target first PUCCH resource in the at least two first PUCCH resources, the RRC signaling may indicate, in addition to the first spatial correlation information set configured independently for the second PUCCH resource, an association relationship between the spatial correlation information in the first spatial correlation information set and the MAC CE signaling.

For example, as shown in fig. 5, when the TRP1 and TRP2 are downlink transmitted simultaneously, the UE needs to transmit UCI for downlink transmission corresponding to the TRP1 and TRP2, respectively, at the same time.

Specifically, the network device configures a PUCCH1 (i.e., a first PUCCH) for the TRP1 and the TRP2, respectively, and may carry, in a case where two PUCCH1 resources are partially non-orthogonal (i.e., collide) in time domain or frequency domain, HARQ ACK/NACK information and CSI that would otherwise need to be carried by two PUCCH1 resources through a predefined PUCCH2 resource (i.e., a second PUCCH resource), so as to transmit the HARQ ACK/NACK information and CSI (i.e., UCI) through spatially-related information corresponding to a PUCCH2 resource.

Then, when the network device configures a spatial correlation information set for the PUCCH2 resource through RRC signaling, the target spatial correlation information corresponding to the PUCCH2 resource may multiplex identification information (i.e., an indication of the spatial correlation information) corresponding to the PUCCH1 configured for the TRP1, specifically, identification information #00# of the spatial correlation information corresponding to the PUCCH1 resource through MAC CE signaling, and use the spatial correlation information corresponding to the identification information in the spatial correlation information set corresponding to the PUCCH2 resource as the target spatial correlation information for transmitting the HARQ ACK/NACK information and CSI, thereby implementing multiplexing of the indication of the spatial correlation information corresponding to the PUCCH1 of the TPR 1; optionally, the association relationship between the MAC CE signaling and the target space related information is preconfigured through RRC signaling.

Optionally, in other embodiments of the present invention, in addition to independently configuring the spatial correlation information set for the PUCCH2 resource through RRC signaling, the network device may also indicate, through MAC CE signaling, identification information of the spatial correlation information corresponding to the PUCCH2 resource, that is, an indication of the spatial correlation information set and the spatial correlation information corresponding to the PUCCH2 resource that are independently configured. In this way, the spatial correlation information corresponding to the identification information of the spatial correlation information corresponding to the PUCCH2 resource indicated by the MAC CE signaling in the spatial correlation information set corresponding to the PUCCH2 resource may be used as the target spatial correlation information for transmitting the HARQ ACK/NACK information and CSI described above.

Optionally, under the condition that the corresponding first spatial correlation information set is not independently configured for the second PUCCH resource, the target spatial correlation information may be obtained in the spatial correlation information set corresponding to the first PUCCH resource by multiplexing the indication of the spatial correlation information corresponding to the first PUCCH resource.

Specifically, the target spatial correlation information belongs to a second spatial correlation information set, and the second spatial correlation information set is a spatial correlation information set corresponding to at least one target first PUCCH resource.

It is to be understood that the second set of spatial correlation information may be indicated by RRC signaling corresponding to at least one target first PUCCH resource of the at least two first PUCCH resources, and the identification information of the spatial correlation information corresponding to the at least one target first PUCCH resource may be indicated by MAC CE signaling corresponding to the at least one target first PUCCH resource of the at least two first PUCCH resources, thereby indicating the target spatial correlation information in the second set of spatial correlation information based on the identification information.

Optionally, the second spatial correlation information set includes at least one spatial correlation information corresponding to at least one target first PUCCH resource of the at least two first PUCCH resources.

For example, as shown in fig. 6, when the TRP1 and TRP2 are downlink transmitted simultaneously, the UE needs to transmit UCI for downlink transmission corresponding to the TRP1 and TRP2, respectively, at the same time.

Then, in the case that the network device does not configure the spatial correlation information set for the PUCCH2 resource, the target spatial correlation information corresponding to the PUCCH2 resource may be determined by multiplexing the spatial correlation information set corresponding to the PUCCH1 configured for the TRP1 and the identification information of the spatial correlation information (i.e., an indication of the spatial correlation information), specifically, the identification information #00# of the spatial correlation information corresponding to the PUCCH1 resource is indicated through MAC CE signaling, and the spatial correlation information corresponding to the identification information in the spatial correlation information set corresponding to the PUCCH1 resource is used as the target spatial correlation information for transmitting the HARQ ACK/NACK information and the CSI, so that multiplexing of the spatial correlation information set corresponding to the PUCCH1 of the TPR1 and the indication of the spatial correlation information is achieved.

Optionally, in the case that there is no first spatial correlation information set preconfigured for the second PUCCH resource, the target spatial correlation information may also be determined according to downlink transmission configuration information corresponding to at least one target first PUCCH resource in the at least two first PUCCH resources.

Specifically, the target spatial correlation information is spatial correlation information determined according to downlink transmission configuration information, and the downlink transmission configuration information corresponds to at least one target first PUCCH resource.

Optionally, the downlink transmission configuration information may include transmission configuration information of a PDCCH, transmission configuration information of a PDSCH, transmission configuration information of a core Resource Set (Control Resource Set), or transmission configuration information of a Search space (Search space).

Optionally, the at least one target first PUCCH resource is a first PUCCH resource with a lowest resource identifier or a highest resource identifier in the at least two first PUCCH resources.

Preferably, the at least one target first PUCCH resource is a first PUCCH resource with a lowest resource identifier among the at least two first PUCCH resources.

It can be understood that, when the number of the first PUCCH resources with the lowest or highest resource identifier in the at least two first PUCCH resources is one, the number of the target first PUCCH resources is one; when the number of the first PUCCH resources with the lowest or the highest resource identifier among the at least two first PUCCH resources is plural, the number of the target first PUCCH resources is plural.

Optionally, when the target spatial correlation information is spatial correlation information corresponding to at least two first PUCCH resources, for different time instants of the second PUCCH resource in the time domain, the target spatial correlation information corresponding to each time instant is spatial correlation information corresponding to different first PUCCH resources.

It may be understood that, at least two first PUCCH resources may be used as a target first PUCCH resource, at this time, a set of spatial correlation information corresponding to the at least two first PUCCH resources and an indication of the spatial correlation information may be multiplexed, and for different time instants of the second PUCCH resource in the time domain, the spatial correlation information corresponding to the different first PUCCH resources may be used as the target spatial correlation information for each time instant.

For example, as shown in fig. 7, when the TRP1 and TRP2 are downlink transmitted simultaneously, the UE needs to transmit UCI for downlink transmission corresponding to the TRP1 and TRP2, respectively, at the same time.

Then, in case that the network device configures a set of spatial correlation information for the PUCCH2 resource through RRC signaling, target spatial correlation information corresponding to the PUCCH2 resource, identification information (i.e., indication of spatial correlation information) of spatial correlation information corresponding to the PUCCH1 configured for TRP1 and TRP2, specifically identification information #00# of spatial correlation information corresponding to each PUCCH1 resource indicated by MAC CE signaling, for different time instants of the PUCCH2 resource in the time domain (i.e., slot as shown in the figure), the spatial correlation information corresponding to each identification information in the spatial correlation information set corresponding to the PUCCH2 resource is used as the target spatial correlation information, for transmitting the HARQ ACK/NACK information and CSI at different time instances, the target spatial correlation information corresponding to each time instance may be determined in a beam scanning manner, thereby enabling multiplexing of indications of spatial correlation information and corresponding to PUCCH1 of TPR1 and TPR2, respectively.

As shown in fig. 8, when the TRP1 and TRP2 perform downlink transmission simultaneously, the UE needs to perform UCI transmission for downlink transmissions corresponding to the TRP1 and TRP2, respectively, at the same time.

Then, in the case that the network device does not configure a spatial correlation information set for the PUCCH2 resource, the target spatial correlation information corresponding to the PUCCH2 resource may be multiplexed with the spatial correlation information set corresponding to the PUCCH1 configured for the TRP1 and the TRP2, and the identification information #00# of the spatial correlation information corresponding to each PUCCH1 resource, specifically, the spatial correlation information corresponding to the identification information in the spatial correlation information set corresponding to each PUCCH1 resource is used as the target spatial correlation information corresponding to each time point for different time points of the PUCCH2 resource in the time domain (i.e., slot shown in the figure), so as to transmit the HARQ ACK/NACK information and CSI at different time points, specifically, the target spatial correlation information corresponding to each time point may be determined in a beam scanning manner, thereby enabling multiplexing of the spatial correlation information set and the indication of the spatial correlation information corresponding to the PUCCH1 of TPR1 and TPR2, respectively.

Optionally, a time division multiplexing mode or a beam scanning mode may be adopted, and spatial correlation information corresponding to different first PUCCH resources is respectively adopted at different times of the second PUCCH resource in the time domain.

In another specific embodiment of the present invention, the target spatial correlation information is spatial correlation information corresponding to at least one target first PUCCH resource in a plurality of first PUCCH resources, where the plurality of first PUCCH resources include at least two first PUCCH resources.

It may be appreciated that, in determining the target spatial correlation information corresponding to the second PUCCH resource, the indication of the spatial correlation information and the set of spatial correlation information corresponding to at least one target first PUCCH resource of the plurality of first PUCCH resources may be multiplexed based on a plurality of first PUCCH resources including at least two first PUCCH resources configured for the terminal device.

Optionally, the at least one target first PUCCH resource is a first PUCCH resource with a lowest or highest resource identifier among the plurality of first PUCCH resources.

Preferably, the at least one target first PUCCH resource is a first PUCCH resource with a lowest resource identifier among the plurality of first PUCCH resources.

It can be understood that when the number of the first PUCCH resources with the lowest or highest resource identifier in the plurality of first PUCCH resources is one, the number of the target first PUCCH resources is one; when the number of the first PUCCH resources with the lowest or highest resource identifier among the plurality of first PUCCH resources is plural, the number of the target first PUCCH resources is plural.

Optionally, the plurality of first PUCCH resources correspond to a plurality of downlink transmission channels of the same type, and downlink transmission channels corresponding to any two first PUCCH resources in the plurality of first PUCCH resources are different; the at least one target first PUCCH resource is a first PUCCH resource corresponding to a target downlink transmission channel in the plurality of first PUCCH resources, and the target downlink transmission channel is a downlink transmission channel corresponding to a primary receiving and transmitting point TRP in the plurality of downlink transmission channels.

It is to be appreciated that in determining the target spatial correlation information corresponding to the second PUCCH resource, reference may be made to multiplexing a set of spatial correlation information corresponding to a primary TRP and an indication of the spatial correlation information, where the primary TRP is opposite to the secondary TRP.

Optionally, the target spatial correlation information belongs to a third set of spatial correlation information, and the third set of spatial correlation information corresponds to at least one target first PUCCH resource.

It is to be understood that, in the case where a corresponding first spatial correlation information set is not independently configured for the second PUCCH resource, the third spatial correlation information set may be indicated through RRC signaling corresponding to at least one target first PUCCH resource of the plurality of first PUCCH resources, and identification information of spatial correlation information corresponding to the at least one target first PUCCH resource may be indicated through MAC CE signaling corresponding to the at least one target first PUCCH resource of the plurality of first PUCCH resources, thereby indicating the target spatial correlation information in the third spatial correlation information set based on the identification information.

Optionally, the third spatial correlation information set includes at least one spatial correlation information corresponding to at least one target first PUCCH resource in the multiple first PUCCH resources.

Optionally, the target spatial correlation information is spatial correlation information determined according to downlink transmission configuration information, and the downlink transmission configuration information corresponds to at least one target first PUCCH resource.

It can be understood that, in the case that there is no first spatial correlation information set preconfigured for the second PUCCH resource, the target spatial correlation information may also be determined according to downlink transmission configuration information corresponding to at least one target first PUCCH resource in the plurality of first PUCCH resources.

Optionally, in this embodiment of the present invention, each of the spatial correlation information may indicate at least one synchronization information block identifier, or CSI-RS identifier, or SRS (Sounding Reference Signal) identifier, respectively.

Corresponding to the method for information transmission performed by the terminal device in fig. 4, an embodiment of the present invention further provides a method for information transmission, which is applied to a network device. Referring to fig. 9, the method includes:

s201: receiving Uplink Control Information (UCI) transmitted based on the target space related information, wherein the UCI is borne on a second PUCCH resource, the UCI comprises all or part of the UCI borne by at least two first PUCCH resources, and the at least two first PUCCH resources collide with each other.

Optionally, the at least two first PUCCH resources may be a time domain collision, a frequency domain collision, or both a time domain collision and a frequency domain collision, where the time domain collision may refer to that the at least two first PUCCH resources occupy 1 same symbol, and the frequency domain collision may refer to that the at least two first PUCCH resources occupy 1 same subcarrier; the second PUCCH resource may specifically be a PUCCH resource that is not in conflict with the at least two first PUCCH resources and that is pre-configured for the terminal device by the network device.

It is to be understood that the at least two downlink transport channels belonging to the same type may be physical downlink shared channels, PDSCHs.
