Description

Feedback method, transmission method, signaling transmission method and corresponding devices of communication channel

Technical Field

The present invention relates to the field of wireless communication, and in particular, to a feedback method, a transmission method, a signaling transmission method, and a corresponding apparatus for a communication channel.

Background

In order to meet the increasing demand for wireless data services from the deployment of 4G (4th-Generation, 4th Generation) communication systems, efforts have been made to develop improved 5G (5th-Generation, 5th Generation) communication systems. The 5G communication system is also referred to as a "4G-behind network" or a "LTE-behind (Long Term Evolution) system".

5G communication systems are implemented in higher frequency bands (e.g., above 3 GHz) in order to achieve higher data rates. High-frequency communication has relatively serious path loss and penetration loss, and is closely related to the atmosphere in space propagation. Because the wavelength of the high-frequency signal is extremely short, a large number of small-sized antenna arrays can be applied, so that the beam forming technology can obtain more accurate beam directions, the coverage capability of the high-frequency signal is improved by the advantages of the narrow beam technology, the transmission loss is compensated, and the method is a great characteristic of high-frequency communication.

In a communication system using beamforming techniques, transmit beamforming and/or receive beamforming is used. Transmit beamforming is generally a technique that focuses the signal transmitted by each antenna in a particular direction using multiple antennas. The combination of the plurality of antennas is referred to as an array antenna, and each antenna included in the array antenna is referred to as an antenna element. The propagation of signals is increased due to the use of transmit beamforming and the interference to other users is significantly reduced because almost no signals are received in other directions than the relevant direction. Receive beamforming is a technique in which reception of radio waves is focused in a specific direction by using a receive antenna array in a receiver. The signal sensitivity of the signal entering in the relevant direction is increased by using the reception beamforming, but the signal entering in a direction other than the relevant direction is removed from the reception signal, thereby blocking the interference signal.

In a conventional LTE system, a control channel only supports open-loop transmission, and a data channel supports Multiple transmission schemes, such as single-port transmission, transmission diversity, open-loop MIMO (Multiple Input Multiple Output) spatial multiplexing, and closed-loop MIMO spatial multiplexing, so channel measurement and feedback in LTE are mainly used for transmission of the data channel. In the 5G communication system, beam-based communication channel (including control channel) transmission is an indispensable technology due to the transmission limitation of the high frequency band. On the other hand, the design requirement of the 5G communication system considers the unified design and flexible configuration of various use cases that may be faced in future communication, and needs to consider reliability, real-time performance, transmission efficiency, resource overhead, expandability, and the like, so the 5G communication system puts higher requirements on the design of the communication channel, and the corresponding feedback and transmission technology also puts new challenges, and how to design the management, feedback, and transmission technology of the beams of the control channel and the data channel in a unified and flexible manner is a problem to be solved in the research of the 5G communication system.

the first method is as follows:

the UE feeds back N pieces of beam information, wherein the first P pieces of beams in the N pieces of beams are used for controlling the transmission of a channel, and the value of P is fixed or configured by a base station or indicated in the feedback information of the current UE. It is assumed here that the beams in the set of beam information fed back by the UE are numbered in a specified order, for example, it is assumed that the set of beams includes N beams, and the numbers are [0, N-1 ]. The specified order here may be that the beams in the group of beams fed back by the UE are sorted and fed back to the base station according to a predetermined rule that the beam signal quality is good to bad, or according to a predetermined rule that the beam usage priority is first to last. Preferably, the value of P may be bound to a transmission scheme supported by the control channel, and is 1 assuming that the control channel supports single port transmission and 2 assuming that the control channel supports SFBC transmission diversity. As shown in fig. 7, the first or the best beam of the N beams fed back by the UE is used for control channel transmission, and the base station selects the first or the best beam thereof by default for control channel transmission after receiving the N beam information fed back by the UE. Or preferably, the value of P is equal to N, i.e. the UE assumes that N beams are all used for control channel transmission. Or preferably, the indication information of the value of P is included in the UE feedback information.

As another implementation manner of the embodiment of the present invention, the first P ' beams of the N beams are used for transmitting a data channel, where P ' is fixed or indication information of the value of P ' is also included in the UE feedback information.

Preferably, the UE assumes that the transmission mode of the control channel is predetermined (i.e. fixed, such as SFBC), and the data channel is transmitted according to space division multiplexing, where the number of transmitted layers is RI.

As shown in fig. 9, the UE assumes that the first RI _ c beams fed back by the UE are used for control channel transmission, and the UE assumes that the first RI _ d beams of the N beams fed back by the UE are used for data channel transmission, where the value indication information of RI _ c and RI _ c is included in the UE feedback information. Preferably, it is assumed that both the control channel and the data channel support spatial multiplexing transmission, and thus RI _ c and RI _ d indicate the values of RI for the layers of the control channel and the data channel, respectively.

The designated group may be pre-agreed by the base station and the terminal, or may be indicated by the UE feedback information. For example, the base station and the terminal agree that the first packet of the M packets of the N beams is used for control channel transmission, or the base station and the terminal agree that the first packet of the M packets of the N beams includes two packets for control channel transmission, as shown in fig. 10.

As another mode of the embodiment of the present invention, the UE feeds back N pieces of beam information and the N pieces of beam grouping information, and assumes that a designated one of the N pieces of beam grouping information is used for transmission of a data channel, and the data channel is transmitted based on the designated group, and the UE receives the data channel on a reception beam corresponding to the designated group. The designated group may be pre-agreed by the base station and the terminal, and the indication information of the designated group may also include the UE feedback information. For example, the base station and the terminal agree that the first packet of M packets of the N beams is used for control channel transmission.

Preferably, the control channel herein may be applicable to a control channel of any one of the multi-level channels; control channels, base stations and UEs of different levels of the multi-level control channels may determine the beam ranges for the respective levels of control channels in different specified manners. For example, it is assumed that two-level control channel transmission is supported, where for a first level control channel, the base station and the UE determine a transmission beam or a beam range for the level control channel according to a first specified manner, and for a second level control channel, the base station and the UE determine a transmission beam or a beam range for the level control channel according to a second specified manner, where the first specified manner is one of the three manners, the second specified manner is one of the three manners, and the first specified manner and the second specified manner may be the same or different.

Example 3

This embodiment illustrates a feedback scheme of a communication channel when there is a binding relationship between a multi-level feedback and a multi-level control channel: wherein, the UE is a receiving end, and the base station is a transmitting end.

In this embodiment, taking the feedback information including K levels as an example, the base station has multiple levels or multiple types of control channels, where a binding relationship exists between the multiple levels of feedback and the multiple types of control channel transmission. Preferably, the binding relationship between the multi-level feedback information and the multi-level/type control channels is predetermined by the base station and the terminal. Preferably, the binding relationship between at least one level of feedback information in the multi-level feedback information and at least one level/type of control channel transmission in the multi-level/type of control channel is predetermined by the base station and the terminal, and other binding relationships may be configured by the base station.

Preferably, there is a predetermined relationship between the transmission opportunity of the multilevel control channel and the feedback time of the multilevel feedback information, for example, the ith level beam feedback information is transmitted at time n, and the transmission opportunity of the corresponding ith level control channel is transmitted at time i + k, where k is a fixed value greater than or equal to 4, or k is configured through higher layer signaling/broadcast signaling.

Preferably, a predetermined correspondence exists between the multilevel control channels and the transmission modes, where the transmission modes include transmission schemes such as single-port transmission, transmission diversity, open-loop spatial multiplexing, and closed-loop spatial multiplexing. As fig. 11 assumes that K has a value of 2, the UE assumes that the first-stage control channel is transmitted by using SFBC transmission, and the UE assumes that the second-stage control channel is transmitted by using closed-loop spatial multiplexing transmission.

Specifically, there are K-level feedback for the UE, L-level or L-type control channels for the base station, and the following situations:

the first condition is as follows: when K is equal to L, there is a one-to-one correspondence between K-level feedback information and L-level/type control channels. For example, as shown in fig. 11, the ith-level control channel corresponds to the ith-level beam feedback information, the UE assumes that the ith-level beam feedback information is used for transmission of the ith-level control channel, the base station transmits the ith-level control channel by using the ith-level beam feedback information, and the UE receives the control channel according to the assumed correspondence. For example, as shown in fig. 12, assuming that values of K and L are equal to 3, a corresponding relationship exists between the primary control channel and the primary beam feedback information, the UE assumes that the primary control channel performs transmission based on the primary beam feedback information, the base station sends the primary control channel according to the primary beam feedback information, and so on, a corresponding relationship exists between the secondary control channel and the secondary beam feedback information, and a corresponding relationship exists between the tertiary control channel and the tertiary beam feedback information.

Case two: when K is greater than L, one way is that there is a one-to-one correspondence (or binding) relationship between the designated L-level feedback information in the K-level feedback information and the L-level/type control channel, where the designated L-level in the K-level feedback information is pre-agreed by the base station and the terminal or configured by the base station. In another mode, the K-level feedback information may be divided into L-level feedback information, where each type of feedback information includes one-level or multi-level feedback information, and there is a one-to-one correspondence (or binding) relationship between the L-level feedback information and the L-level/type control channels. For example, as shown in fig. 13, it is assumed that the value of K is 3, the value of L is 2, the first-level feedback information and the second-level feedback information in the K-level feedback information form first-type feedback information, the third-level feedback information is second-type feedback information, and the first-type feedback information and the second-type feedback information respectively have a correspondence with the first-level/type control channel and the second-level/type control channel.

Case three: when K is less than L, there is a one-to-many correspondence between K-level feedback information and L-level/type control channels. The K levels/types of control channels may be divided into K sets of control channels, where each set of control channels contains one or more levels/types of control channels. There is a one-to-one correspondence between the K-level feedback information and the K sets of control channels. For example, assume that the value of K is 2, the value of L is 3, a first level/type of control channel in the level/type of control channels is a first group of control channels, a second level/type and a third level/type of control channel in the level/type of control channels are a second group of control channels, and there is a correspondence between first level feedback information and second group feedback information and the first group of control channels and the second group of control channels, respectively. Preferably, when the first-level feedback information corresponds to multiple levels/types of control channels, the base station and the terminal may poll and transmit the multiple levels/types of control channels in a predetermined manner, or the base station transmits one level/type of control channels of the multiple levels/types of control channels as needed, or the multiple levels/types of control channels are respectively bound with different resources, where the resources include resources such as a time domain, a frequency domain, a code domain, and a reference signal port. Preferably, at least one feedback information exists in the K-level feedback information and between the L-level/type control channels, and a binding relationship exists between the first-level/type control channels, where the binding relationship is predetermined by the base station and the terminal.

Example 4

This embodiment illustrates a feedback scheme of a communication channel when a control channel and a data channel independently feed back: wherein, the UE is a receiving end, and the base station is a transmitting end.

The UE feeds back two types (or called two sets) of beam feedback information, and the two types of feedback information respectively have binding relations with a control channel and a data channel. The UE assumes that two types of feedback information are used for transmission of the control channel and the data channel, respectively. The beam feedback information herein may include one or more of one or more beam index/identification information, one or more (beam) resource index/identification information, RSRP information corresponding to one or more beams, channel quality information corresponding to one or more beams, and beam grouping information of one or more beams, wherein the channel quality information includes channel matrix information, covariance matrix information of a channel matrix, Channel Quality Indication (CQI) information, Precoding Matrix Indication (PMI) information, and layer indication (RI) information.

The binding relationship between the two types of beam feedback information and the control channel and the data channel can be explicitly or implicitly notified:

mode 1: each type of beam feedback information has an identifier, such as a set identifier (set ID or class ID for short), the base station identifies the binding relationship between the type of beam feedback information and the control channel or the data channel through the class ID, for example, as shown in table 1, each type of beam feedback information includes one set ID information, when the set ID value indicates 0, the type of beam feedback information is the beam feedback information of the control channel, and when the set ID value indicates 1, the type of beam feedback information is the beam feedback information of the data channel:

TABLE 1

set ID	Beam feedback information
		0	Beam feedback information for control channels
1	Beam feedback information for data channels

Mode 2: the beam feedback information of each type and the feedback resource have a certain binding relationship, and the base station determines the binding relationship between the beam feedback information of the type and the control channel or the data channel through the receiving resource. For example, as shown in fig. 14, one Transmission Unit (TU) includes a Downlink Control (DC) Transmission region, a Data (Data) Transmission region, a Guard Period (GP) for short, and an Uplink (UL) Transmission region, where the UL Transmission region is used to transmit first-type beam feedback information and second-type beam feedback information, and in fig. 14, the first-type beam feedback information and the second-type beam feedback information respectively occupy two different time domain resources (same frequency domain resource) for Transmission in a time division manner, where the first time domain resource is used to transmit beam feedback information of a control channel, and the second time domain resource is used to transmit beam feedback information of a Data channel; as shown in fig. 15, the first type of beam feedback information and the second type of beam feedback information respectively occupy two frequency domain resources (same time domain resources) in a frequency division manner to be transmitted, where the first frequency domain resource is used for transmitting beam feedback information of a control channel, and the second time domain resource is used for transmitting beam feedback information of a data channel.

Mode 3: each type of beam feedback information and the feedback channel type have a certain binding relationship, and the base station obtains the binding relationship between the corresponding type of beam feedback information and the control channel or the data channel by receiving different feedback channel types. For example, as shown in fig. 16, a Physical Uplink Control Channel (PUCCH for short) and a Physical Uplink Shared Channel (PUSCH for short) have a binding relationship with two types of feedback information, where the PUCCH is used for feeding back beam feedback information of the Control Channel and the PUSCH is used for feeding back beam feedback information of the data Channel. As also shown in fig. 17, it is assumed that there are two levels of control channels for the control channels, PUCCH format 1 is used for beam information feedback of a Downlink (DL) first level control channel, PUCCH format 2 is used for beam information feedback of a second level control channel, PUCCH format 3 is used for beam information feedback of a Downlink data channel, and PUSCH may be configured for beam information feedback of the first control channel or the second level control channel or the Downlink data channel.

The base station may indicate, through signaling (e.g., in aperiodic feedback), feedback enable and/or feedback time of at least one of two types of beam information of a control channel, and feedback two types of independent beam feedback information to be respectively used for the control channel and a data channel or for feeding back one type of shared beam feedback information, for example, as shown in table 2, when the base station configures a signaling bit to 00, the base station indicates to the UE to trigger feedback of beam information related to the control channel, and/or the feedback time, feedback frequency domain resource, and feedback channel type of the beam information (beam information of a default control channel and beam information independent feedback of the data channel); when the base station configures the signaling bit to be 01, indicating to the UE to trigger feedback of beam information related to the data channel, and/or feedback time, feedback frequency domain resource, and feedback channel type of the beam information (beam information of a default control channel and beam information of the data channel are fed back independently); when the base station configures the signaling bit as 10, indicating to the UE to trigger the feedback of the control channel related to the control channel and the beam information related to the data channel at the same time, and/or indicating the feedback time, the feedback frequency domain resource, and the feedback channel type (beam information of the default control channel and beam information of the data channel are fed back independently) of the two types of beam information, respectively; when the base station configures the signaling bit to be 11, indicating to the UE that beam feedback independent feedback of the control channel and the data channel is not triggered, or triggering feedback that the control channel and the data channel share a type of beam information, and/or feedback time, feedback frequency domain resource, and feedback channel type of the type of beam information:

TABLE 2

For the latter case (control signaling bit 11), there is a certain predetermined corresponding relationship between the default data channel beams and the control channel beams of the base station and the user, for example, all the data channel beams are control channel beams, or the first N optimal beams in the data channel beams are control channel beams, and the like, which can be referred to embodiment 2 of the present invention specifically.

If the control channel has multiple stages, beam feedback information of multiple sets can be considered for transmission of the multiple stages of control channels and data channels, respectively. For example, the first-level control channel is in a transmission diversity mode, the second-level control channel is in a space division multiplexing mode, and the second-level supports Modulation and Coding Scheme (MCS) adaptation, so that the UE feeds back three sets of beam feedback information to the base station, which are respectively used for the first-level control channel, the second-level control channel, and the data channel. Wherein, the beam feedback information of the first set only includes the beam information or the resource information corresponding to the beam, and the beam feedback information of the second set includes the CQI/PMI/RI information in addition to the beam information or the resource information corresponding to the beam; the beam feedback information of the third set includes beam information for the data channel or resource information and CQI/PMI/RI information corresponding to the beam.

As a mode of the embodiment of the present invention, a base station indicates, to a terminal, a transmission beam for a control channel and a data channel or switching information of the transmission beam by using two independent signaling; as another implementation manner of the embodiment of the present invention, the base station indicates, to the terminal, the receiving beam or the switching information of the receiving beam for the control channel and the data channel by using two independent signaling. Preferably, the two independent signalings may be included in one control channel or may be included in different control channels.

Although the embodiments of the present invention have been described above, the contents thereof are merely embodiments adopted to facilitate understanding of the technical aspects of the present invention, and are not intended to limit the present invention. It will be apparent to persons skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
