Description

Communication channel transmission and receiving method, device, base station and terminal

Technical Field

The present invention relates to the field of communications, and in particular, to a method, an apparatus, a base station, and a terminal for transmitting and receiving a communication channel.

Background

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

5G communication systems are considered to be implemented in higher frequency bands (e.g., above 3 GHz) in order to accomplish higher data rates. The high-frequency communication is characterized by relatively serious path loss and penetration loss, and has close relation with the atmosphere in space transmission. Because the wavelength of the high-frequency signal is extremely short, a large number of small 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 using the advantage of the narrow beam technology, the transmission loss is compensated, and the method is a great characteristic of high-frequency communication.

In the LTE system, the downlink physical control channel mainly includes two types, one is common to the terminals, and the other is specific to the terminals. The control channel common to the terminals is mainly used to indicate some common information to the terminals, for example, system messages, random access grant messages, etc., which can be received by all terminals in the cell. The terminal-specific control channel is mainly used to indicate to the terminal some terminal-specific information, which can only be received by the target terminal. In LTE, the control channel common to the terminals is sent omni-directionally, and the control channel specific to the terminals is sent omni-directionally or directionally, where the directional transmission is implemented by means of digital precoding. At each scheduling time unit, the terminal receives the physical downlink control channel in a blind detection manner, that is, the terminal needs to attempt to receive and demodulate the control channel in the first several symbols of each scheduling time unit.

In the LTE system, an important role of the downlink physical control channel is to indicate transmission related information of a data channel to a terminal. In LTE, the data channel also employs omni-directional or directional transmission, wherein the directional transmission is implemented by means of digital precoding.

In a 5G communication system, a hybrid precoding structure is introduced, namely, a digital precoding technology and an analog beamforming technology are adopted to transmit a control channel and a data channel at the same time. In a hybrid precoding structure, one radio frequency link can only transmit one beam at the same time, and therefore, under the multi-beam condition, it is necessary to scan a plurality of different beam directions over a plurality of times to complete omnidirectional or quasi-omnidirectional transmission of a control channel or a data channel. This increases the resource overhead for communication channel transmission. In addition, compared to LTE, the number of scheduling time units is multiplied within an equal time interval, and the complexity of blind detection of the control channel is multiplied.

Therefore, in the related art, the transmission of the communication channel has the problems of large resource overhead and high receiving complexity.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

Method embodiment

The method provided by the first embodiment of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Taking an example of the operation on a mobile terminal, fig. 1 is a hardware block diagram of the mobile terminal of a communication channel receiving method according to an embodiment of the present invention. As shown in fig. 1, the mobile terminal 10 may include one or more (only one shown) processors 102 (the processor 102 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA), a memory 104 for storing data, and a transmitting device 106 for communication functions. It will be understood by those skilled in the art that the structure shown in fig. 1 is only an illustration and is not intended to limit the structure of the electronic device. For example, the mobile terminal 10 may also include more or fewer components than shown in FIG. 1, or have a different configuration than shown in FIG. 1.

The memory 104 may be used to store software programs and modules of application software, such as program instructions/modules corresponding to the receiving method of the communication channel in the embodiment of the present invention, and the processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, so as to implement the method described above. The memory 104 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

In one example, the transmission device 106 includes a Network adapter (NIC), which can be connected to other Network devices through a base station so as to communicate with the internet. In one example, the transmission device 106 may be a Radio Frequency (RF) module, which is used to communicate with the internet in a wireless manner.

Since the design of the 5G communication system has higher requirement on the delay, it has been proposed in the discussion of 3GPP to support designs of multiple subcarrier intervals and symbol lengths, that is, the 5G communication system can support designs of shorter Orthogonal Frequency Division Multiplexing (OFDM) symbols and shorter scheduling time units.

The design of the 5G communication system is oriented to more scenes and can meet various requirements, so that the 3GPP discussion proposes to support a multi-level downlink control channel for satisfying different levels of requirements on robustness and spectral efficiency of the control channel. However, how to smoothly implement the switching between the multi-level downlink control channels and how to reasonably design the resource multiplexing of the multi-level downlink control channels and the data channels to maximally save the resource overhead while ensuring the transmission performance is a problem to be considered.

In view of the above problems of large resource overhead, high complexity of blind detection, and low multiplexing efficiency in communication channel transmission, an effective solution has not been proposed yet.

In this embodiment, a transmission method of a communication channel operating in a base station is provided, and fig. 2 is a flowchart of the transmission method of the communication channel according to the embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:

step S202, transmitting a first communication channel, wherein a signaling carried by the first communication channel and/or a transmission manner of the first communication channel indicates at least one of the following information: terminal scheduling information, transmission mode of the second communication channel.

Through the steps, when the first communication channel is transmitted, the terminal is indicated to schedule the indication information and the transmission mode information of the second communication channel, so that the problems of high resource overhead and high receiving complexity in the transmission of the communication channels in the related technology are effectively solved, the resource overhead is effectively reduced, and the receiving complexity of the communication channels can be effectively reduced.

Optionally, the main body of the above steps may be a base station, a network control entity similar to the base station, or the like, but is not limited thereto. In fig. 2, the base station transmits the step S202 to the terminal as an example.

The terminal scheduling information may include: and terminal grouping information, wherein the terminal grouping information comprises indication information of one or more terminal groups.

Preferably, the terminal scheduling information herein refers to indication information that the terminal is scheduled or not scheduled. Optionally, the terminal scheduling information is terminal grouping information, where the terminal grouping information includes indication information of one or more terminal groups.

For example, the terminal grouping information herein may include group index indication information of one or more terminal groups for indicating terminal groups scheduled or not scheduled for a current or specified duration.

The terminal groups scheduled in the current or specified duration time indicate that the base station may send control channels and data services to the terminals in the terminal groups in the current or specified duration time, and the terminals need to try to receive the control channels and the data services in the current or specified duration time;

the terminal groups which are not scheduled within the current or specified duration time refer to that the base station will not send control channels and data services to the terminals within the terminal groups within the current or specified duration time, and the terminals will not receive the control channels and data services within the current or specified duration time.

Optionally, the terminal scheduling information includes terminal grouping information in a current scheduling time unit or in a specified period of time unit. Preferably, the specified period of time unit includes a specified scheduled time unit, a specified duration period starting from the current scheduled time unit, or a specified duration period starting from a specified time. Preferably, the specified time unit, the specified time period unit, the specified scheduling time unit and the specified time duration period can be indicated to the terminal through signaling carried by the first communication channel and/or higher layer signaling. The scheduling time unit comprises one or more time units, and the time units are time slots, subframes, frames, OFDM symbols or minislots.

For example, the terminal group information may include at least one of: terminal grouping information in the current scheduling time unit; terminal grouping information in a designated scheduling time unit; terminal grouping information within a specified duration from a current scheduling time unit; grouping information of terminals starting from the designated scheduling time unit and within the designated duration period.

It should be noted that the "time unit" and the "scheduling time unit" described in the embodiments of the present invention have the following relationship, one time unit may be one OFDM symbol, one time slot, one micro-slot, one subframe, or one frame, and one scheduling time unit may include one or more time units.

Optionally, the method further includes: terminals are grouped in a predefined (or pre-agreed) manner. The grouping of the terminals may be performed by the base station or the terminals.

The predefined ways include: grouping the terminals according to one of the following formulas:

the formula I is as follows: UE _ ID mod M = i;

the formula II is as follows: (UE _ ID mod M + Offset) mod M = i;

the formula III is as follows: offset mod M = i.

Wherein, UE _ ID represents the terminal identification, M represents M groups in total, the value of M is a nonnegative integer, the value of parameter Offset is configurable, i belongs to { 0-M-1 } represents that the terminal with the terminal identification of UE _ ID is divided into ith group. The terminal identifier is a unique identifier that is distinguished from other terminals, and for example, in LTE, the terminal identifier is composed of a 16-bit secondary bit sequence. Preferably, M is an integer greater than 1. The value of M may be indicated to the terminal by the base station, for example, in some cases, the value of M is equal to 1, i.e., the terminal is not grouped, and in some cases, the value of M is greater than 1, i.e., the terminal needs to be grouped. The value of M may also be predetermined by the base station and the terminal.

It should be noted that the indexes of M packets are defined as 0 to M-1, which is mainly for convenience of description and distinguishing between different packets, and actually, the indexes of M packets may also be defined in other manners as long as different packets can be distinguished, for example, the indexes of M packets are 1 to M, and in this case, i ∈ {0 to M-1} indicates that the terminal identified as UE _ ID is divided into i +1 th packets.

Preferably, the parameter Offset is an integer having a value range of {0 to M-1}, and the default value of the parameter Offset is 0. When the terminal receives the indication information of the parameter Offset, the terminal determines the packet to which the terminal belongs according to the indicated value of the Offset, and when the indication information of the parameter Offset is not received, the terminal defaults that the value of the Offset is 0.

The predefined manner may also include: the terminals are grouped according to terminal capabilities, wherein the terminal capabilities may include at least one of bandwidth capabilities of the terminals, beam capabilities of the terminals, and types of services that can be supported by the terminals. Wherein a predefined correspondence exists between terminal capabilities and terminal groups. Preferably, the bandwidth capability herein refers to a maximum frequency domain bandwidth that can be supported by the terminal, and the beam capability herein refers to a number of beams that can be simultaneously sent by the terminal or a maximum number of radio frequency links (sometimes, TXRU) that can be supported by the terminal, where the service types at least include eMBB (enhanced Mobile Broadband), URLLC (Ultra-Reliable and Low Latency Communications, low Latency high reliability connections), eMTC (massive Machine Type Communications, large-scale internet of things), and the like.

Optionally, the transmission mode of the second communication channel may be indicated by the transmission mode of the first communication channel in various manners, for example, the following manners may be adopted: a predefined correspondence exists between the transmission mode of the first communication channel and the transmission mode of the second communication channel. The transmission mode of the first communication channel and the transmission mode of the second communication channel herein may refer to the same or different transmission mode parameters, for example, the transmission mode of the first communication channel and the transmission mode of the second communication channel both refer to transmission schemes, that is, there is a correspondence between the transmission scheme of the first communication channel and the transmission scheme adopted by the second communication channel, and preferably, the transmission scheme adopted by the second communication channel is an optional range of one transmission scheme; for another example, the transmission mode of the first communication channel refers to an aggregation level, and the transmission mode of the second communication channel refers to a Modulation and Coding Scheme (MCS), that is, there is a predefined correspondence between the aggregation level of the first communication channel and the Modulation and Coding level of the second communication channel, and preferably, the Modulation and Coding level corresponding to the second communication channel is a selectable range of Modulation and Coding levels.

In the above method for transmitting and indicating a communication channel, the first communication node may transmit the first communication channel to the second communication node, and indicate at least one of the terminal scheduling information and the transmission mode information of the second communication channel through the transmission mode of the first communication channel and/or the carried signaling.

Preferably, the first communication channel may be a control channel or a broadcast channel, and the second communication channel may be a control channel or a data channel, for example, when the first communication channel is a control channel, the control channel includes: a common control channel, or a control channel shared by a plurality of terminals. It should be noted that the control channel herein is preferably a control channel specific to the terminal. The second communication channel may be located in a different scheduled time unit than the first communication channel, and it is also possible that the second communication channel is the same type of communication channel as the first communication channel, and in the extreme, the second communication channel is the first communication channel. For example, the first communication channel is a control channel, and the second communication channel is a data channel; the first communication channel is a public control channel, and the second communication channel is a terminal-specific control channel; the first communication channel and the second communication channel are both control channels dedicated to the terminal and are the same control channel corresponding to the same terminal.

Optionally, transmitting the first communication channel (control channel) comprises: transmitting a control channel on a specified time unit pattern, wherein the specified time unit pattern comprises one or more time units, a time unit comprising one of: a slot, subframe, frame, symbol, or minislot.

For example, when the first communication channel is a public (downlink) control channel (a downlink control channel common to terminals or a downlink control channel at a cell level) or a downlink control channel shared by multiple terminals, the base station only allows transmission of the control channel on a specified time unit pattern, that is, on the allowed time unit pattern, transmission or non-transmission of the control channel is autonomously determined by the base station, but the terminal needs to monitor/blindly detect the control channel on each time unit on the time unit patterns. Wherein the specified time cell pattern can be determined by at least one of: the broadcast channel or synchronization signal or higher layer signaling is indicated to the terminal or in a predefined manner. Wherein the time unit pattern may comprise one or more consecutive or non-consecutive time units, a time unit being a slot, a subframe, a frame, a symbol (preferably an OFDM symbol in downlink), or a minislot. Here, the control channel shared by multiple terminals may also be a control channel shared by a terminal group, that is, the control channel may be received by multiple terminals or terminal groups.

Optionally, transmitting the first communication channel (control channel) further comprises: the control channel is repeatedly transmitted in a plurality of designated time units, wherein the control channel is transmitted in a plurality of time units by using different transmission beams or transmission beam groups.

Optionally, the repeatedly transmitting the control channel over the specified plurality of time units comprises at least one of: a predefined correspondence exists between the transmission order of the transmit beams of the transmission control channel and the transmission order of the transmit beams or transmit beam groups employed by the synchronization signal; a predefined correspondence exists between the transmission order of the transmit beams of the transmission control channel and the transmission order of the transmit beams or transmit beam groups employed by the broadcast channel; a predefined correspondence exists between the time units for transmitting the control channel and the time units for transmitting the synchronization signals; there is a predefined correspondence between time units for transmitting control channels and time units for transmitting broadcast channels.

For example, the transmission of the control channel is performed over a plurality of time units, wherein the control channel may be transmitted using different transmit beams or transmit beam groups, respectively, over the plurality of time units. Optionally, there is a predefined correspondence between the transmission beam/dummy beam group order and the transmission order of the transmission beam or transmission beam group used by the synchronization signal or broadcast channel. Optionally, there is a predefined correspondence between the transmission resources of the control channel (e.g. time units in which the control channel is transmitted) and the transmission resources employed by the synchronization signal or the broadcast channel (e.g. time units in which the control channel is transmitted), preferably the transmission resources of the control channel and the transmission resources employed by the synchronization signal or the broadcast channel occupy the same time domain resources. Preferably, the maximum number of transmission layers supported by the first communication channel is smaller than the maximum number of transmission layers supported by the second communication channel.

When there are multiple types (or multiple classes) of control channels, the first communication channel is only one type of control channel. For example, the first communication channel may be a terminal-specific control channel, wherein the terminal-specific control channel comprises at least one of the following characteristics: support multi-stream/multi-layer transmission; support a spatial multiplexing transmission scheme; the Modulation scheme is supported by a Modulation scheme such as Quadrature Phase Shift Keying (QPSK), for example, a Modulation scheme such as 16QAM (Quadrature Amplitude Modulation); transmitting in a data channel region; supporting Modulation and Coding Scheme (or Modulation and Coding Scheme) (MCS for short) adaptive transmission, wherein the MCS adaptive means that a base station can adaptively adjust the MCS level according to channel quality state measurement information fed back from a terminal; rank (rank) adaptive transmission is supported, wherein the number of transmission layers/rank (rank) adaptive refers to that the base station can adaptively adjust the number of transmission layers/rank according to channel quality state measurement information fed back from the terminal.

The first communication channel may be multiplexed with the second communication channel, and the first communication channel may be located in a second communication channel region for transmission, where the second communication channel region is defined in the scheduling unit for the second communication channel, for example, a data channel region or a control channel region. Preferably, the control channel comprises at least two types, wherein one type is a basic control channel, the other type is an enhanced control channel, and the first communication channel is an enhanced control channel. The transmission mode of the basic control channel is predefined, and the transmission mode of the enhanced control channel can be indicated through the basic control channel. The enhanced control channel may support better code rate, more spectrally efficient information transmission, and may be used to indicate transmission of a higher level data channel. The basic control channel is a fallback form of the enhanced control channel. When the channel condition is good, the base station will transmit the enhanced control channel to indicate the transmission of the data channel, and when the channel condition is bad, the base station will transmit the basic control channel to indicate the transmission of the data channel. When the data channel is indicated by the enhanced control channel, the data channel is advanced with information indicated by the enhanced control channel (enhanced/advanced transmission), and when the data channel is indicated by the basic control channel, the data channel is basic with information indicated by the basic control channel (basic/coarse/more robust transmission).

This type of control channel (first communication channel) may support an Automatic transmission reQuest (HARQ) mechanism, such as receiving ACK/NACK acknowledgement information for the first communication channel prior to transmission of the second communication channel, where ACK indicates that the first communication channel was received correctly and NACK indicates that the first communication channel was not received correctly.

And the base station transmits a second communication channel according to the received ACK information or NACK information, wherein when the ACK information is received, the second communication channel is transmitted according to the indication of the first control channel, and when the NACK information is received, the second communication channel is transmitted according to the indication of the second control channel, wherein the first control channel is a first communication channel, and the second control channel is other control channels different from the first control channel.

It is to be noted that, as a preferred embodiment of the present invention, the second control channel does not have a feature included when the first control channel is the control channel specific to the terminal. Alternatively, the second control channel may be a control channel transmitted before the second communication channel, wherein the second control channel is another or other type of control channel distinct from the first control channel;

for example, the second control channel may be a control channel transmitted before and closest to the second communication channel, where the second control channel is another or other type of control channel distinct from the first control channel.

Preferably, the second control channel is a control channel transmitted before the second communication channel, wherein the second control channel is another or other type of control channel different from the first control channel;

preferably, the second control channel is a control channel transmitted before and closest to the second communication channel, wherein the second control channel is another or other type of control channel distinct from the first control channel.

Optionally, transmitting the first communication channel may further include: the transmission of the first communication channel supports a hybrid automatic repeat request, HARQ, transmission mechanism.

Preferably, the transmission of the first communication channel supporting the hybrid automatic repeat request HARQ transmission mechanism comprises: and receiving the ACK information or the NACK information of the first communication channel, wherein the ACK information is used for indicating that the first communication channel is correctly received, and the NACK information indicates that the first communication channel is not correctly received.

For example, after receiving the ACK signal, the base station transmits the data channel according to the transmission mode information indicated by the enhanced control channel, and after receiving the NACK signal, the base station transmits the data channel according to the transmission mode information indicated by the basic control channel. For the terminal, when it feeds back an ACK signal to the base station, the terminal will receive the second communication channel as indicated by the first communication channel, and when it feeds back a NACK signal to the base station, the terminal will receive the second communication channel as indicated by the other type of control channel.

Assuming that the maximum number of transmission layers supported by the first communication channel is P layers and the maximum number of transmission layers supported by the second communication channel is W layers, where P and W are both positive integers and the value of P is less than W, then the first P ports in the DMRS pattern (e.g., assuming that the demodulation reference signal port is defined as port [0,7], the first P ports are [0, P-1], P is less than the total number of ports of the demodulation reference signal resource, i.e., P is less than 8) are DMRS ports shared by the first communication channel and the second communication channel, and the remaining W-P ports are DMRS ports exclusive to the second communication channel. The terminal may support multiple sets of DMRS patterns that are employed when the first communication channel is transmitting in the second communication channel region, and other DMRS patterns that are otherwise employed. Wherein the other patterns are different patterns from the above-mentioned patterns, for example, the other DMRS patterns are DMRS ports for the second communication channel all at a start position of the second communication channel region.

In fig. 4,

time slots

3, 6 and 9 may be used for transmitting the common downlink control channel, and other time slots do not transmit the common downlink control channel.

After obtaining the scheduling time unit pattern, the terminal attempts to receive the common downlink control channel only in the time unit indicating that the common downlink control channel is available for transmission, and does not attempt to receive the common downlink control channel in other scheduling time units.

As another implementation manner of the embodiment of the present invention, the common downlink control channel may also be a downlink control channel common to the terminal group.

Preferred embodiment 3

The downlink control channel supports two levels of downlink control channels, wherein the transmission configuration of the first level of downlink control channel is relatively fixed, the resource configuration is configured through semi-static signaling in advance, and a more robust transmission scheme is adopted for transmission, for example, space Frequency Block Code (SFBC for short); the second-stage downlink control channel has more flexible transmission configuration, and the resource configuration may be indicated by the first-stage control channel and supports a transmission scheme with higher spectrum efficiency, for example, single User-Multiple-Input-Multiple-Output (SU-MIMO). The first level downlink control channel is located in the downlink control channel region for transmission, and the second level control channel may be located in the data channel region for transmission.

Since the channel environment and the data channel of the second-level control channel are both located in the data channel region, there is often a correspondence between the transmission mode of the second-level control channel and the data channel. The correspondence may be predetermined by the base station and the terminal.

Assuming that the second-stage control channel supports maximum 2-layer SU-MIMO transmission, SFBC, cyclic Delay Diversity (CDD), and the data channel supports maximum 8-layer SU-MIMO transmission, SFBC, CDD, the second-stage control channel transmission scheme and the data channel transmission scheme have the following correspondence:

when the second stage USS adopts SU-MIMO (2-layer) transmission, the transmission scheme range corresponding to the Physical Downlink Shared Channel (PDSCH) is SU-MIMO (5-8 layers);

when the second stage USS adopts SU-MIMO (1 layer) transmission, the transmission scheme range corresponding to the PDSCH is SU-MIMO (1-4 layers);

when the second stage USS adopts SFBC transmission, the transmission scheme range corresponding to the PDSCH is { SFBC, CDD, SU-MIMO (1-2 layers) }.

The base station determines a transmission scheme range corresponding to the PDSCH through a transmission scheme of a second-level control channel, selects one transmission scheme from the transmission scheme range according to channel measurement feedback information to transmit a current data channel, and indicates the selected transmission scheme information to the terminal through a signaling carried in the second-level control channel; and the base station determines the transmission scheme range corresponding to the PDSCH through the transmission scheme of the second-level control channel, determines the currently adopted transmission scheme of the PDSCH according to the received signaling indication carried in the second-level control channel, and then receives and demodulates the PDSCH. Wherein the second level control channel may indicate the selected transmission scheme to the terminal through 2-bit signaling.

As another implementation manner of the embodiment of the present invention, there is a correspondence relationship between a modulation and coding scheme of the second-level control channel and a modulation and coding scheme of the data channel.

As another implementation manner of the embodiment of the present invention, there is a correspondence relationship between the aggregation level of the second-level control channel and the modulation and coding scheme of the data channel.

As another implementation manner of the embodiment of the present invention, there is a correspondence relationship between a modulation scheme of the second-level control channel and a modulation coding scheme of the data channel.

Preferred embodiment 4

The downlink control channel supports two levels of downlink control channels, wherein the transmission configuration of the first level of downlink control channel is relatively fixed, the resource configuration is configured through semi-static signaling in advance and a more robust transmission scheme is adopted for transmission, such as SFBC; the transmission configuration of the second level downlink control channel is more flexible, the resource configuration of the second level downlink control channel can be indicated by the first level control channel, and the transmission scheme with higher spectrum efficiency, such as SU-MIMO, is supported. The first level downlink control channel is located in the downlink control channel region for transmission, and the second level control channel may be located in the data channel region for transmission.

Since the channel environment and the data channel of the second level control channel are both located in the data channel region, a set of DMRS patterns may be shared between the second level control channel and the data channel. However, considering that the data channel also supports SU-MIMO transmission, due to the higher requirement of robustness for control channel transmission, the maximum number of transmission layers supported by the second-stage downlink control channel under SU-MIMO is usually smaller than the maximum number of transmission layers supported by the data channel.
