Description

Communication channel transmission method, device and system
Technical Field
The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for transmitting a communication channel.
Background
In order to meet the increasing demand for wireless data services from 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 "post 4G network" or a "post LTE (Long Term Evolution ) system".
A 5G communication system is considered to be implemented in a higher frequency band (e.g., above 3 GHz) in order to achieve higher data rates. The high-frequency communication is characterized by relatively serious path loss and penetration loss, and the communication 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 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 advantage of the narrow beam technology, the transmission loss is compensated, and the method is a great characteristic of high-frequency communication.
In communication systems using beamforming techniques, transmit beamforming and/or receive beamforming is used. Transmit beamforming is generally a technique that uses multiple antennas to concentrate the signal transmitted by each antenna in a particular direction. 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. Propagation of the signal increases due to the use of transmit beamforming, and interference to other users is significantly reduced because the signal is hardly received in other directions than the relevant direction. Reception beamforming is a technique in a receiver that concentrates reception of radio waves in a specific direction by using a reception antenna array. The signal sensitivity of the signal entering in the correlation direction is increased by using the reception beamforming, but the signal entering in the direction other than the correlation direction is removed from the reception signal, thereby preventing the interference signal.
In the LTE system, since the terminal receives both the physical downlink control channel (PDCCH, physical Downlink Control Channel) and the physical downlink shared channel (PDSCH, physical Downlink Shared Channel) in an omni-directional manner, the terminal can receive and store the PDSCH during the PDCCH decoding delay, and can be used for decoding the PDSCH after the PDCCH decoding is completed. However, in a communication system using beamforming, a terminal receives a downlink control channel and a data channel by means of a beam, and since the control channel and the data channel have different requirements for transmission performance, for example, the control channel often requires higher transmission robustness, and the data channel often requires higher transmission efficiency, there is a situation that the transmission scheme or transmission/reception beam of the control channel and the data channel are not identical correspondingly, fig. 1 is a schematic diagram of decoding delays of the control channel and the data channel corresponding to different reception beams according to the related art of the present invention, as shown in fig. 1, the control channel (PDCCH) is received by using a beam 1, and the data channel (PDSCH) scheduled by the control channel is received by using a beam 2. Since there is only one data channel and control channel, and the control channel is one-to-one controlled, in this case, the terminal cannot determine the reception beam of the data channel before the control channel is not completely decoded, which will cause a problem that the data channel cannot be accurately received during the decoding delay of the control channel.
In addition, the 5G or future communication system also puts higher demands on the reliability and real-time performance of link communication, and the scheme that one control channel corresponds to one data channel in the related technology obviously cannot cope with.
In view of the above problems existing in the related art, no effective solution has been found yet.

The present embodiment includes a plurality of specific embodiments for describing the present application in detail in conjunction with different scenarios:
example 1
Fig. 6 is a schematic diagram of scheduling N data channels by N control channels in the embodiment of the present invention, as shown in fig. 6, a data service sent by a base station to a terminal 1 (UE 1) is divided into N (n=2 in the figure) data blocks, each of which is transmitted by N data channels, and before the data channel is transmitted, the base station sends N control channels to the terminal, each of which is used for scheduling the N data channels, that is, each of which is used for indicating transmission configuration information of the N data channels to the terminal. The transmission configuration information includes a transmission scheme of the data block (for example, single antenna transmission/transmission diversity/open loop MIMO/closed loop MIMO), a transmission/reception beam/precoding weight/beamforming weight adopted by the data block transmission, a time domain resource occupied by the data block transmission, a frequency domain resource occupied by the data block transmission, a modulation class adopted by the data block transmission, a coding class adopted by the data block transmission, a demodulation reference signal adopted by the data block transmission, and the like.
One of the N control channels is a master control channel and the remaining control channels are referred to as slave control channels. The master control channel is necessary, and the slave control channels are in some cases not, and the slave control channels are present or not and the presence of several slave control channels is controlled by the master control channel. I.e. the base station informs the terminal via the primary control channel whether there are secondary control channels, several secondary control channels, the time-frequency resource positions of the secondary control channels, etc. The secondary control channel is typically located temporally after the primary control channel, i.e. by transmitting the secondary control channel only after the primary control channel has been transmitted. For example, in fig. 6, PDCCH1 is a master control channel, PDCCH2 is a slave control channel, and the base station indicates to the terminal, via PDCCH1, the time-frequency resource positions including 1 slave control channel (PDCCH 2) and slave control channel PDCCH 2.
The base station instructs the terminal 1 of transmission configuration information of data channels PDSCH1 and PDSCH 2 transmitted by the base station to the terminal 1 through a main control channel PDCCH1 and a slave control channel PDCCH 2, respectively. Specifically, there may be two ways, one way is that the main control channel PDCCH1 and the slave control channel PDCCH 2 each independently indicate the transmission configuration information of the PDSCH1 and the transmission configuration information of the PDSCH 2, that is, the main control channel PDCCH1 indicates all the transmission configuration information of the PDSCH1 to the terminal 1, and the slave control channel PDCCH 2 indicates all the transmission configuration information of the PDSCH 2 to the terminal 1, and fig. 7 is a schematic diagram of a correspondence relationship between N control channels and N data channels in the case that N control channels respectively schedule N data channels in the embodiment of the present invention, as shown in fig. 7; another way is that the main control channel PDCCH1 indicates common transmission configuration information of the data channels PDSCH1 and PDSCH 2 and transmission configuration information unique to PDSCH1, PDCCH 2 indicates only transmission configuration information unique to PDSCH 2, fig. 8 is a schematic diagram of another correspondence relationship between N control channels and N data channels in the case that N control channels schedule N data channels respectively in the embodiment of the present invention, as shown in fig. 8, for example, the main control channel PDCCH1 indicates to terminal 1 that the transmission scheme of PDSCH1 (single antenna transmission/transmission diversity/open loop MIMO/closed loop MIMO), the transmit/receive beam/precoding weight/beamforming weight used for PDSCH1 transmission, the modulation coding level used for PDSCH1, the demodulation reference signal used for PDSCH1, the time-frequency resource used for PDSCH1, and PDCCH 2 indicates only the time-frequency resource used for PDSCH 2 to terminal 1, and the base station configures other transmission configuration information (transmission scheme, transmit/receive beam/precoding weight/beamforming weight, modulation coding level, demodulation reference signal) of PDSCH 2 to be the same as PDSCH1, i.e. the configuration information of PDSCH1 is that the PDSCH1 and the PDSCH 2 can be further configured to obtain the transmission configuration information of PDSCH 2 by the terminal 1 and the reception location of PDSCH 2 by configuring the common transmission configuration information of PDSCH 1.
The transmission of the master control channel PDCCH 1 and the slave control channel PDCCH 2 have the same transmission scheme and reception scheme. The transmission method includes at least one of a main control channel, a transmission beam/precoding weight/beamforming weight used for transmission from the control channel, a transmission scheme (e.g., single antenna transmission/transmission diversity/open loop MIMO/closed loop MIMO), and a demodulation reference signal. The reception scheme here includes at least one of reception beam/precoding weight/beamforming weight of the main control channel and the slave control channel, and reception scheme (e.g., single antenna reception/multi-antenna diversity reception, single beam reception/multi-beam reception, wide beam reception/narrow beam reception). The base station configures the same transmission mode for the main control channel PDCCH 1 and the slave control channel PDCCH 2, and the terminal defaults to receive the two control channels according to the same receiving mode. Thus, there is no problem in that the decoding delay between the two control channels causes the failure to accurately receive from the control channel.
As still another implementation manner of the embodiment of the present invention, after the transmission of the primary control channel, the secondary control channel may also transmit according to a transmission manner agreed in advance, or the transmission manner of the secondary control channel may be determined according to the transmission manner of the primary control channel, or the transmission manner of the secondary control channel is indicated to the terminal in the primary control channel. The terminal assumes that the slave control channel and the master control channel are received in the same manner, i.e., the terminal will receive the slave control channel in the same manner as the master control channel. For example, to save resources occupied by the secondary control channel, the secondary control channel may transmit in a predefined manner with a higher modulation and coding rate than the primary control channel, with a simpler transmission scheme, e.g., in single-antenna or two-antenna transmit diversity. In general, the slave control channel may transmit in a transmission scheme different from that of the master control channel, but the transmission scheme adopted is that the base station and the terminal have a predetermined binding relationship with the transmission scheme of the master control channel or may be obtained from the received information in the master control channel.
As a further implementation of the embodiment of the present invention, the data channel scheduled by the control channel may also be an uplink data channel. For example, the data channel in fig. 6 may also be a physical channel (PUSCH, physical Uplink Shared Channel) for carrying uplink data, and the downlink control channel in fig. 6 carries uplink grant information (before downlink grant information) for indicating transmission configuration information of an uplink data block sent by the terminal to the base station. Or, among N data channels scheduled by the N control channels, there are both an uplink data channel (PUSCH) and a downlink data channel (PDSCH).
Example 2
Fig. 9 is a schematic diagram of scheduling one data channel by N control channels in the embodiment of the present invention, as shown in fig. 9, a data service transmitted by a base station to a terminal 1 (UE 1) is transmitted by one data channel, i.e., one PDSCH, and before the data channel is transmitted, the base station transmits N (n=2 in the figure) control channels (i.e., PDCCH1 and PDCCH2 in the figure) to the terminal 1 for scheduling the data channel PDSCH, i.e., the base station indicates transmission configuration information of the data channel PDSCH to the terminal 1 using 2 control channels. The transmission configuration information includes a transmission scheme of the data channel (for example, single antenna transmission/transmission diversity/open loop MIMO/closed loop MIMO), a transmit/receive beam/precoding weight/beamforming weight adopted by the data channel transmission, a time domain resource occupied by the data channel transmission, a frequency domain resource occupied by the data channel transmission, a modulation class adopted by the data channel transmission, a coding class adopted by the data channel transmission, a demodulation reference signal adopted by the data channel transmission, and the like.
Among the 2 control channels, PDCCH1 is a master control channel, and PDCCH2 is a slave control channel. The main control channel PDCCH1 indicates the first type of transmission configuration information to the terminal 1, and the control channel PDCCH2 indicates the second type of transmission configuration information to the terminal 1. The first type of transmission configuration information is convenient for the terminal 1 to receive and buffer the corresponding PDSCH part at least first in the data channel region and during the delay caused by the decoding of the PDCCH2, so that after the decoding of the PDCCH2 is completed, the terminal 1 receives and decodes the PDSCH according to the transmission configuration information indicated by the PDCCH1 and the PDCCH2 together. For example, the first type of transmission configuration information includes a transmission/reception beam/precoding weight/beamforming weight adopted by PDSCH transmission, a time-frequency resource occupied by PDSCH transmission, and the second type of transmission configuration information includes the remaining transmission configuration information except the first type of transmission configuration information in all transmission configuration information of PDSCH, for example, a transmission scheme (for example, single antenna transmission/transmission diversity/open loop MIMO/closed loop MIMO) of PDSCH, a modulation coding level adopted by PDSCH transmission, a demodulation reference signal adopted by PDSCH transmission, and the like.
In this embodiment, if the master control channel indicates the existence of the slave control channels to the terminal, the base station and the terminal default to 1 slave control channel, that is, if the master control channel indicates the slave control channels to the terminal through 1 bit, for example, if the bit value is 0, the number of slave control channels is 0, and if the bit value is 1, the number of slave control channels is 1.
Preferably, the secondary control channel and the primary control channel adopt the same transmission mode and reception mode, the base station transmits the secondary control channel using the same transmission mode as the primary control channel, and the terminal receives the secondary control channel using the same transmission mode as the primary control channel assuming that the secondary control channel and the primary control channel use the same transmission mode. The transmission method includes at least one of a main control channel, a transmission beam/precoding weight/beamforming weight used for transmission from the control channel, a transmission scheme (e.g., single antenna transmission/transmission diversity/open loop MIMO/closed loop MIMO), and a demodulation reference signal. The reception scheme here includes at least one of reception beam/precoding weight/beamforming weight of the main control channel and the slave control channel, and reception scheme (e.g., single antenna reception/multi-antenna diversity reception, single beam reception/multi-beam reception, wide beam reception/narrow beam reception).
As still another implementation manner of the embodiment of the present invention, the slave control channel may perform transmission and reception according to an agreed transmission/reception manner, or there may be an agreed relationship (or referred to as a binding relationship) between the transmission/reception manner of the slave control channel and the transmission/reception manner of the master control channel, or the slave control channel may directly instruct through the master control channel. When there is a certain agreed relation between the transmission/reception mode of the slave control channel and the transmission/reception mode of the master control channel, the base station determines the transmission mode of the slave control channel according to the agreed relation, the terminal obtains the transmission mode information of the slave control channel according to the agreed relation, determines the reception mode of the slave control channel, and receives the slave control channel according to the reception mode.
As an implementation manner of the embodiment of the present invention, the data channel scheduled by the control channel may also be an uplink data channel. For example, the data channel in fig. 9 may be a physical channel (PUSCH, physical Uplink Shared Channel) for carrying uplink data, and the downlink control channel in fig. 9 carries uplink grant information (before downlink grant information) for indicating transmission configuration information of an uplink data block sent by the terminal to the base station.
Example 3
Fig. 10 is a schematic diagram of scheduling M data channels by N control channels in the embodiment of the present invention, as shown in fig. 10, a data service transmitted by a base station to a terminal 1 (UE 1) is transmitted by M (m=4 in the figure) data channels (PDSCH 1 to 4), and before the data channel transmission, the base station transmits N (n=2 in the figure) control channels (i.e., PDCCH1 and PDCCH2 in the figure) to the terminal 1 for scheduling 4 data channels, i.e., the base station indicates transmission configuration information of the data channels PDSCH1 to 4 to the terminal 1 using 2 control channels. The transmission configuration information of one data channel includes a transmission scheme of the data channel (for example, single antenna transmission/transmission diversity/open loop MIMO/closed loop MIMO), a transmit/receive beam/precoding weight/beamforming weight adopted by data channel transmission, a time domain resource occupied by data channel transmission, a frequency domain resource occupied by data channel transmission, a modulation class adopted by data channel transmission, a coding class adopted by data channel transmission, a demodulation reference signal adopted by data channel transmission, and the like.
PDCCH1 in the two control channels is a master control channel, and PDCCH2 is a slave control channel. All transmission configuration information of the four data channels PDSCH1 to 4 is divided into two parts, the main control channel PDCCH1 indicates the first part of transmission configuration information to the terminal 1, and the control channel PDCCH2 indicates the second part of transmission configuration information to the terminal 1. The intersection between the two parts of transmission configuration information is empty, and the intersection is all transmission configuration information of the four data channels PDSCH 1-4. For example, the first part of transmission configuration information is common transmission configuration information of the M data channels, the second part of transmission configuration information is a set of proprietary transmission configuration information of the M data channels, or the first part of transmission configuration information is common transmission configuration information of the M data channels and proprietary transmission configuration information of the first data channel, and the second part of transmission configuration information is a set of proprietary transmission configuration information of M-1 data channels other than the first data channel among the M data channels. The public transmission configuration information includes at least one information of a transmission scheme of a data channel (single antenna transmission/transmission diversity/open loop MIMO/closed loop MIMO), a sending/receiving beam/precoding weight/beamforming weight adopted by the data channel transmission, a modulation class adopted by the data channel transmission, a coding class adopted by the data channel transmission, and a demodulation reference signal adopted by the data channel transmission.
Preferably, the intersection between the transmission configuration information of each part may not be null, for example, some important transmission configuration information of the data channel may be repeatedly transmitted on a plurality of control channels, so as to improve the transmission reliability or robustness of the transmission configuration information.
In this embodiment, if the master control channel indicates the existence of the slave control channels to the terminal, the base station and the terminal default to 1 slave control channel, that is, if the master control channel indicates the slave control channels to the terminal through 1 bit, for example, if the bit value is 0, the number of slave control channels is 0, and if the bit value is 1, the number of slave control channels is 1.
Preferably, the secondary control channel and the primary control channel adopt the same transmission mode and reception mode, the base station transmits the secondary control channel using the same transmission mode as the primary control channel, and the terminal receives the secondary control channel using the same transmission mode as the primary control channel assuming that the secondary control channel and the primary control channel use the same transmission mode. The transmission method includes at least one of a main control channel, a transmission beam/precoding weight/beamforming weight used for transmission from the control channel, a transmission scheme (e.g., single antenna transmission/transmission diversity/open loop MIMO/closed loop MIMO), and a demodulation reference signal. The reception scheme here includes at least one of reception beam/precoding weight/beamforming weight of the main control channel and the slave control channel, and reception scheme (e.g., single antenna reception/multi-antenna diversity reception, single beam reception/multi-beam reception, wide beam reception/narrow beam reception).
Preferably, the same transmission mode and/or receiving mode is adopted between the data channels, the base station will use the same transmission mode to transmit each data channel, and the terminal assumes that the M data channels adopt the same transmission mode and uses the same receiving mode to receive the M data channels. The transmission method includes at least one of transmission beam/precoding weight/beamforming weight used for data channel transmission, transmission scheme (e.g., single antenna transmission/transmission diversity/open loop MIMO/closed loop MIMO), and demodulation reference signal. The reception scheme here includes at least one of a reception beam/precoding weight/beamforming weight used for data channel transmission, and a reception scheme (e.g., single antenna reception/multi-antenna diversity reception, single beam reception/multi-beam reception, wide beam reception/narrow beam reception).
As still another implementation manner of the embodiment of the present invention, the slave control channel may perform transmission and reception according to an agreed transmission/reception manner, or there may be an agreed relationship (or referred to as a binding relationship) between the transmission/reception manner of the slave control channel and the transmission/reception manner of the master control channel, or the slave control channel may directly instruct through the master control channel. When there is a certain agreed relation between the transmission/reception mode of the slave control channel and the transmission/reception mode of the master control channel, the base station determines the transmission mode of the slave control channel according to the agreed relation, the terminal obtains the transmission mode information of the slave control channel according to the agreed relation, determines the reception mode of the slave control channel, and receives the slave control channel according to the reception mode.
As an implementation manner of the embodiment of the present invention, the data channel scheduled by the control channel may also be an uplink data channel. For example, the data channel in fig. 6 may also be a physical channel (PUSCH, physical Uplink Shared Channel) for carrying uplink data, and the downlink control channel in fig. 10 carries uplink grant information (before downlink grant information) for indicating transmission configuration information of an uplink data block sent by the terminal to the base station. Or, among the M data channels, there are both an uplink data channel (PUSCH) and a downlink data channel (PDSCH).
Example 4
Fig. 11 is a schematic diagram of scheduling M data channels by one control channel in the embodiment of the present invention, as shown in fig. 11, a data service transmitted by a base station to a terminal 1 (UE 1) is transmitted by using M (m=4 in the figure) data channels (PDSCH 1 to 4), and before the data channel transmission, the base station transmits N (n=1 in the figure) control channels (i.e. PDCCH in the figure) to the terminal 1 for scheduling 4 data channels, i.e. the base station indicates transmission configuration information of the data channels PDSCH1 to 4 to the terminal 1 using 1 control channel.
The transmission configuration information of each data channel includes a transmission scheme (for example, single antenna transmission/transmission diversity/open loop MIMO/closed loop MIMO) of the data channel, a transmit/receive beam/precoding weight/beamforming weight adopted by data channel transmission, a time domain resource occupied by data channel transmission, a frequency domain resource occupied by data channel transmission, a modulation class adopted by data channel transmission, a coding class adopted by data channel transmission, a demodulation reference signal adopted by data channel transmission, and the like.
The transmission configuration information of the four data channels may have the same or different transmission and/or reception modes. Fig. 12 is a schematic diagram of one control channel scheduling M data channels and M data channels having the same transmission beam in the embodiment of the present invention, for example, fig. 12 shows that the four data channels are transmitted using the same transmission beam, fig. 13 is a schematic diagram of one control channel scheduling M data channels and M data channels having different transmission beams in the embodiment of the present invention, and as shown in fig. 13, the four data channels are transmitted using different transmission beams, respectively.
The transmission and reception modes used for the control channel may be the same as or different from the transmission/reception modes used for the data channel. For example, in fig. 12, the control channel is transmitted using the same transmission beam as the data channel, and when the data channels are transmitted using different transmission beams, respectively, and the control channel is only one, the control channel can be transmitted using a wider beam, and the coverage of the wide beam includes the coverage of the transmission beam of each data channel, for example, in fig. 13, the control channel is transmitted using a different transmission beam than the data channel, and the beam width of the control channel is wider than that of a single data channel.
Preferably, if the transmission configuration information of the four data channels is the same, for example, the transmission scheme of the data channels (for example, single antenna transmission/transmission diversity/open loop MIMO/closed loop MIMO), the transmission/reception beam/precoding weight/beamforming weight used for data channel transmission, the modulation level used for data channel transmission, the coding level used for data channel transmission, the demodulation reference signal used for data channel transmission, etc., the control channel only needs to transmit one set of transmission parameter configuration information for the four data channels, and only indicates the transmission configuration information of the four data channels independently, for example, at least needs to indicate the time-frequency resources of the four data channels independently.
At the receiving end, since the data traffic of the UE1 is divided into four data channels for transmission (PDSCH 1-4), the UE1 can independently decode the four data channels after receiving the indication information of the control channel (PDCCH), so the data channel transmitted first will be decoded first, and it is not necessary to wait until all the data channels are received to start decoding.
As an implementation manner of the embodiment of the present invention, the data channel scheduled by the control channel may also be an uplink data channel. For example, the data channel in fig. 10 may also be a physical channel (PUSCH, physical Uplink Shared Channel) for carrying uplink data, and the downlink control channel in fig. 10 carries uplink grant information (before downlink grant information) for indicating transmission configuration information of an uplink data block sent by the terminal to the base station. Or, among the M data channels, there are both an uplink data channel (PUSCH) and a downlink data channel (PDSCH).
Example 5
Fig. 14 is a schematic diagram of scheduling M data channels by L-class control channels among N control channels in the embodiment of the present invention, as shown in fig. 14, data traffic sent by a base station to a terminal 1 (UE 1) is divided into M (m=2 in the figure) data channels, and is transmitted by N (n=6) control channels. Wherein the 6 control channels include two types of control channels, the first N/2 (=3) control channels are the first type of control channels, and the second N/2 (=3) control channels are the second type of control channels. Preferably, the first 3 control channels are repeatedly transmitted 3 times in the same beam or different beams for PDCCH1, and the last 3 control channels are repeatedly transmitted 3 times in the same beam or different beams for PDCCH 2. In the embodiment of the present invention, the first N/2 (=3) control channels are used to indicate the transmission configuration information of the first data channel thereof to the UE1, and the second N/2 (=3) control channels are used to indicate the transmission configuration information of the second data channel thereof to the UE 1.
As a further implementation of the embodiment of the present invention, the first N/2 (=3) control channels may also be used to indicate a first part of transmission configuration information of the M data channels, and the last N/2 (=3) control channels are used to indicate a second part of transmission configuration information of the M data channels. Wherein the transmission configuration information of the M data channels preferably refers to a union of the respective transmission configuration information of the M data channels; the transmission configuration information of the M data channels is divided into two parts, wherein an intersection between the two parts of transmission configuration information is null and the intersection is the transmission configuration information of the M data channels. The first type of control channel (first N/2 (=3) control channels) in the embodiment of the present invention indicates to the terminal that the first part of the M data channels transmits configuration information, and the second type of control channel (second N/2 (=3) control channels) indicates to the terminal that the second part of the M data systems computers transmits configuration information.
When the current/last 3 control channels are repeatedly sent by the same wave beam, the receiving end can receive by adopting different receiving wave beams so as to improve the receiving performance; when the front/back 3 control channels are repeatedly transmitted in different wave beams, the same or different receiving wave beams can be adopted for receiving, and the transmission robustness and coverage of the control channels are improved through repeated transmission at a transmitting end.
Example 6
When the N control channels include N 1 Main control channels and N-N 1 And when the secondary control channels are used, demodulation reference signal resources are respectively configured for the primary control channel and the secondary control channel, namely, a first demodulation reference signal resource and a second reference signal resource are respectively configured for the primary control channel and the secondary control channel. Preferably, the first demodulation reference signal resource is located before the primary control channel in the time domain, and the second demodulation reference signal resource is located before the secondary control channel in the time domain. Fig. 15 is a first schematic diagram of the configuration of the demodulation reference signals of the N control channel M data blocks in the embodiment of the present invention, and fig. 16 is a second schematic diagram of the configuration of the demodulation reference signals of the N control channel M data blocks in the embodiment of the present invention, for example, as shown in fig. 15/16, where n=2 and N 1 =1, assuming PDCCH1 is the primary control channel for UE1 and PDCCH2 is the secondary control channel for UE 1. PDCCH1 and PDCCH2 each have independently configured demodulation reference signal resources and the demodulation reference signals are each located in front of the corresponding control channels in the time domain, e.g., in fig. 15/16, the control channel first reference signal is located before PDCCH1 and the control channel second reference signal resources are located before PDCCH 2. The receiving end firstly receives the demodulation reference signal resource, estimates the transmission channel information of the PDCCH1 through the control channel demodulation reference signal, receives and demodulates the PDCCH1, and similarly estimates the transmission channel information of the PDCCH2 through the control channel demodulation reference signal, and receives and demodulates the PDCCH 2. The control channel and the corresponding demodulation reference signal resource generally use the same transmission beam/precoding weight/beamforming weight.
When the N controls comprise L-type control channels, independent demodulation reference signal resources are respectively configured for the L-type control channels, namely, i-th demodulation reference signal resources are configured for i-th control channels in the L-type control channels. Preferably, the ith demodulation reference signal resource is located before the ith control channel in the time domain. Fig. 17 is a third schematic diagram of demodulation reference signal configuration of M data blocks of N control channels in the embodiment of the present invention, fig. 18 is a fourth schematic diagram of demodulation reference signal configuration of M data blocks of N control channels in the embodiment of the present invention, for example, as shown in fig. 17/18, n=6 and l=2, if PDCCH1 is any one control channel of a first type of control channels, PDCCH2 is any one control channel of a second type of control channels, independent demodulation reference signal resources, that is, a first reference signal of the control channels and a second reference signal resource of the control channels, are respectively configured for the first type of control channels (3 PDCCHs 1) and the second type of control channels (3 PDCCHs 2), all the first type of control channels share the first reference signal resource, all the second type of control channels share the second reference signal resource, the first reference signal resource of the control channels is located before the first type of control channels, and the second reference signal of the control channels is located before the second type of control channels. The receiving end firstly receives the received reference signal resource, estimates the transmission channel information of the first type of control channel through the control channel demodulation reference signal, receives and demodulates the first type of control channel, and similarly estimates the transmission channel information of the second type of control channel through the control channel demodulation reference signal, and receives and demodulates the second type of control channel. Preferably, when all control channels in the same type of control channel transmit with the same beam, the transmit beam of the demodulation reference signal configured for the type of control channel is the same as the type of control channel. As a further implementation manner of the embodiment of the present invention, when all control channels located in the same class of control channels are transmitted in different beams, the control channels in the class need to be configured with independent reference signal resources, fig. 19 is a fifth schematic diagram of demodulation reference signal configuration of M data blocks of N control channels in the embodiment of the present invention, as shown in fig. 19, each control channel is configured with independent demodulation reference signal resources, i.e. the ith control channel configures the ith reference signal resource of the control channel, and the position of the reference signal resource in the time domain is located before the corresponding control channel, e.g. the first reference signal resource is located before the first control channel (first PDCCH 1), the second reference signal resource is located before the second control channel (second PDCCH 1), the third reference signal resource is located before the third control channel (third PDCCH 1), the fourth reference signal resource is located before the fourth control channel (first PDCCH 2), and so on.
One demodulation reference signal resource is configured for the M data blocks/data channels, i.e. the M data blocks/data channels share the same demodulation reference signal resource. Preferably, the demodulation reference signal resources are located temporally before the M data blocks/data channels. For example, as shown in fig. 15/17, two data channels PDSCH1 and PDSCH2 of UE1 share one demodulation reference signal resource, i.e., one demodulation reference signal resource is configured for only two data channels of UE1, and the reference signal resource is located before the two data channels in the time domain. The UE1 first receives the data channel demodulation reference signal resources, estimates the transmission channels of the two data channels by the demodulation reference signal resources, and receives and demodulates the two data channels. Preferably, the two data channels have the same transmit beam, and the transmit beam of the demodulation reference signal is the same as the transmit beam of the two data channels.
And allocating and configuring independent demodulation reference signal resources for the M data blocks/data channels, namely allocating and configuring jth demodulation reference signal resources for the jth data block/data channel in the M data blocks/data channels. Preferably, the j-th demodulation reference signal resource is located before the j-th data block/data channel in the time domain. For example, as shown in fig. 17/18, two data channels PDSCH1 and PDSCH2 of UE1 are configured with independent demodulation reference signal resources, a data channel first reference signal resource is configured for PDSCH1, a data channel second reference signal resource is configured for PDSCH2, and the data channel first reference signal resource is located before PDSCH1 and the data channel second reference signal resource is located before PDSCH 2. The UE1 first receives the reference signal resource, estimates the transmission channel of the PDSCH1 according to the received first reference signal resource, receives and demodulates the PDSCH1, estimates the transmission channel of the PDSCH2 according to the received second reference signal resource, and receives and demodulates the PDSCH 2. Preferably, the two data channels have different transmission beams, the transmission beam of the first reference signal resource of the data channel is the same as the transmission beam of the PDSCH1, and the transmission beam of the second reference signal resource of the data channel is the same as the transmission beam of the PDSCH.
