Description

Method and device for transmitting and receiving control information, storage medium Technical field

The present invention relates to communication technologies, and in particular, to a method and apparatus for transmitting and receiving control information, and a storage medium.

Background technique

In the existing Time Division Duplexing (TDD) system of Long Time Evolution (LTE), the uplink and downlink configurations are fixed and configurable, resulting in hybrid automatic weighting under the TDD system. The Hybrid Automatic Repeat reQuest (HARQ) timing relationship is very complicated, which brings many limitations, such as the maintenance mechanism of the feedback timing of the first communication node, the feedback delay is not fixed, and the process management.

As one of the core technologies of 5G communication, high-frequency communication provides effective support for future 5G big data communication. However, one of the characteristics of high-frequency communication is based on beam transmission, which uses beam gain to resist spatial fading in high-frequency communication. The high-frequency beam tends to be a hybrid beam. In this case, the radio frequency link on the base station side is limited, and the number of beams that can be directed at the same time is limited, resulting in physical uplink control channels of multiple users in the existing LTE system (Physical Uplink). The control channel, which is abbreviated as PUCCH, cannot be directly applied to high-frequency communication because the base station receives the uplink control information from multiple users in a directional manner, because different users correspond to different uplink receiving modes. When the base station cannot reach all the uplink receiving directions at the same time, the uplink control information from all users cannot be received, so that the uplink control information of all users cannot be multiplexed by using the existing LTE code division multiplexing. Similarly, if the base station sends downlink control information to multiple terminals in a directional manner, the base station cannot play all directions in the coverage cell range at the same time, and thus cannot use the physical hybrid automatic retransmission indicator channel in the existing LTE (Physical Hybrid ARQ Indicator). The channel, referred to as PHICH) structure, transmits control information of multiple users, and further consideration is needed for the enhancement scheme.

At the same time, 5G, as the future evolution technology of wireless communication, tends to be more flexible in uplink and downlink configuration, and the delay is reduced. At this time, the TDD system tends to be uplink or downlink. With flexible configuration, even if the same transmission unit includes both downlink and uplink, the type of the current transmission unit can be flexibly configured with its type, including the duration and service type. As a result, the existing LTE HARQ timing relationship cannot be directly applied to 5G. TDD system.

In view of the above problems in the related art, there is currently no effective solution.

Or other parameters implicitly notify the time-frequency resource where the first link control resource is located, and the receiving mode of the second communication node corresponding to each first link control resource. If it is a proprietary control signaling, preferably the second communication node only needs to inform the first communication node that it transmits one or more first link control resources of the control information, the first communication node is in the first link control of the notification. The control information may be sent on the resource, and the receiving beam used by the second communication node on the notified first link control resource includes the receiving beam required by the first communication node, such as the receiving beam 1, or the transmitting at this time.

The proprietary control signaling may be semi-static proprietary control signaling, such as a configuration mode of RRC signaling in LTE, and/or dynamic proprietary control signaling, such as a transmission mode of DCI signaling in existing LTE, The target user has only one user, or one user group.

The intersection between the received beam sets of the second communication node corresponding to the different first link control resources in FIG. 5b is empty. In the second implementation manner of this embodiment, the intersection between the received beam sets of the second communication node corresponding to the different first link control resources may be different, and the second communication corresponding to all the different first link control resources The union of the received beam sets of the nodes is a set of all receive beams of the second communication node.

The number of different first link control resources is only an example and does not exclude other numbers. There are three implementation manners for the number of different first link control resources. The first mode of this embodiment is that the first communication node obtains the broadcast information based on the second communication node. The second mode of the embodiment is that the first communication node obtains different first link control resources according to all receiving beams of the second communication node and the maximum number of receiving beams included in each first link control resource. number. For example, if the number of receiving beams corresponding to the second communication node is 12, and the number of receiving beams that can be formed by the second communication node on each first link control resource is 4, the first communication node obtains a different first chain. The number of road control resources is 12/4=3. In the third implementation manner of this embodiment, the number of different first link control resources is variable, and the first communication node is obtained by using dynamic or semi-static signaling information sent by the second communication node.

The signal transmitted on the first communication node is superior to the first communication node, and the first communication node obtains the receive beam required to transmit the control information as the beam 1 according to the channel reciprocity, that is, the second communication node needs to be in the Receiving control information on the receiving beam 1; obtaining according to the receiving manner of the second communication node corresponding to the sending mode of the sending control information, for example, the first communication node selects the transmitting beam 2 to transmit the control information, and the transmitting beam 2 corresponds to the second. The receiving beam of the communication node is beam 1, and the first communication node obtains the first required for transmitting control information. The receiving beam of the communication node is the beam 1; according to the sending manner of the second communication node corresponding to the data corresponding to the control information, for example, the first communication node obtains the second communication node to transmit the data on the second link with the beam 1 The first communication node obtains, according to the reciprocity of the channel, the received beam of the second communication node that is required to transmit the control information, and the transmission mode of the second communication node corresponding to the control signaling corresponding to the data.

The control signaling is used to assist the first communication node to demodulate the data, and the first communication node is based on channel reciprocity. The receiving beam of the second communication node required to obtain its transmission control information is beam 1.

When the receiving manner of the second communication node required by the first communication node to send the control information includes multiple receiving beams, for example, the required receiving beam is obtained as the beam {0, 1, 2}, The first implementation manner of the embodiment is that the first communication node selects only one of the first link control resources corresponding to the receive beam {0, 1, 2}, and the selection principle is agreed by the transceiver party, for example, selecting the most The first link control resource corresponding to the receive beam is preferentially received. If the optimal receive beam is the receive beam 1, the first link control resource with index 1 in FIG. 5b is selected. In the second implementation manner of this embodiment, the first communications node sends the control information on all the first link control resources corresponding to the receiving beam {0, 1, 2}, as shown in FIG. 5b. The control information is sent on the first link control resource whose index is 0, 1, 2. The third implementation manner of this embodiment is that, at this time, the second communication node preferably sends a signaling to notify the first communication node that the first link control resource needs to send control information, and the second communication node may The first link control resource may receive control information by using one of the receive beams {0, 1, 2} or multiple beams.

In this embodiment, for different receiving beams on the same first link control resource, FIG. 5g is a schematic diagram of different communication nodes corresponding to different receiving beam directions on the same first link control resource according to an embodiment of the present invention, as shown in FIG. 5g. The receiving beam of the corresponding second communication node on the first link control resource with the index of 1 includes the beam {1, 4, 7, 10}, and the receiving beam {1, 4, 7, 10} corresponds to the receiving. The first communication node, the control information sent by the third to fifth communication nodes. In the first implementation manner of this embodiment, the first communication node, the third to fifth communication nodes adopt the same demodulation reference signal or the demodulation reference signal port is the same, and it is assumed that the receiving beam 1 of the second communication node is received from The interference of the third to fifth communication nodes transmitting signals is small. At this time, the first communication node shown in FIG. 5g, the control information sent by the third to fifth communication nodes arrive at the second communication node, and the second communication node Distinguish by receiving beam. In the second implementation manner of this embodiment, the first communication node and the third to fifth communication nodes adopt different demodulation reference signals or demodulation reference signal ports, and it is assumed that the receiving beam 1 of the second communication node is received from the first The interference from the third to fifth communication nodes for transmitting signals is relatively large, and cannot be distinguished only by the receiving beams of the second communication node. That is to say, at this time, the interference of the signals transmitted by the third to fifth communication nodes on the receiving beam 1 is relatively large.

In this embodiment, different first link control resources are located after the first communication node prepares the control information.

In this embodiment, the control information includes one or more of the following information: ACK/NACK information of the data corresponding to the control information, channel state CSI information, resource request information, where the channel state CSI information includes the second The transmission mode selection information of the second communication node on the link (the transmission mode selection information indicates that one or more transmission mode selection information is selected in one transmission mode set), the random access request information, and possibly the first link Control information, the first link control information being used to assist the second communication node to receive data on the first link.

Example 6

In the embodiment 5, the first communication node uses the default preferred transmit beam on the determined first link control resource, or sends the control information in an omnidirectional manner. In this embodiment, the first communication node is further configured according to the second communication node. The transmitted signaling information, and/or the manner in which the second communication node receives the control information, selects the transmission mode of the transmission control information.

A link control resource is rotated in all directions to achieve the purpose of omnidirectional transmission in all directions, and may further be a time division and frequency division method, and each group of frequency divisions transmits a group direction, and the first time of multiple time divisions A plurality of groups are sent on the link control resource, so as to achieve the purpose of omnidirectional transmission in each sending direction, and the omnidirectional transmission mode may be notified by the signaling of the second communication node, or may be agreed with the second communication node. Ok. Of course the above In the sending mode, the second communication node on the resource where the control information is sent receives the control information in a corresponding receiving manner.

The transmission mode includes a transmission diversity mode, a repeated transmission mode, a transmission power level, and the like.

In the third implementation manner of this embodiment, the first communication node selects the sending manner of the sending control information according to the receiving manner of the second communication node receiving the control information, and the correspondence between the receiving mode and the sending mode of the first communications node. the way. The correspondence relationship is agreed by the first communication node and the second communication node in advance. For example, when the receiving mode of the second communication node is omnidirectional reception, the first communication node may transmit in a preferred orientation manner, and when the second communication node adopts the directional reception mode, the first communication node may transmit in an omnidirectional manner. Of course, this embodiment does not exclude the direct correspondence between the receiving manner of the other second communications node and the sending manner of the first communications node to send the control information. Or, for example, the second communication node may receive the control information from the first communication node by using the beam {0, 1, 2} on the first link, and the receiving beam {0, 1, 2} sequentially corresponds to the first link. The transmit beam of the first communication node is {3, 4, 7}. At this time, the first communication node determines the transmission mode according to the receiving manner of the second communication node.

The control information is sent on the link control resource, and the sending manner of the first communication node corresponding to the first link control resource (in this embodiment, the transmit beam) is different, and the second communication node is only in the first communication node. The first link control resource corresponding to the associated transmission mode receives its control information by using its corresponding receiving mode. For example, the second communication node determines that the corresponding first communication node's transmit beam is beam 1 and the receive beam is beam 0 in beam training or other stages, and then the second communication node obtains its first link control resource according to the transmit beam 1 The first link control resource with index 1 is then received by the receive beam 0 on the determined first link control resource to receive its corresponding control information. The control information sent by the first communication node is not received on the other first link control resources.

At this time, the second communication node obtains the location of the first link control resource where the transmit beam 1 is located according to the signaling information, or according to a rule agreed with the first communication node, or according to the first chain for the index i0~i2 The receiving beam 0 receives the signal on the path control resource, and then determines the sending mode used by the first communication node on the first link control resource to send the control information by using the corresponding demodulation reference signal, thereby obtaining the first part of the transmitting beam 1 The location of a link control resource is the first link control resource with index 1 in Figure 5h.

In another scenario of this embodiment, the first communications node determines, according to the manner in which the first communications node sends the control information, the manner in which the receiving control information is received, such as the second communications node in the beam training phase or other phases. Determining that it can receive control information from the first communication node on the receive beam {0, 1, 2}, the receive beam {0, 1, 2} sequentially corresponding to the transmit beam of the second communication node is { 1, 4, 7}, the second communication node determines that the first communication node transmits the control information by using the transmit beam 4, and the second communication node determines to receive the control information by using the receive beam 1.

The distance between the second communication node and the second communication node is relatively close, and the communication requirement can be achieved with a wider beam. If the data is a narrow beam transmission, the first communication node needs to transmit based on narrow beams or multiple narrow beam transmissions based on time division. In summary, the correspondence between the data transmission manner and the first communication node transmission mode in this embodiment is only an example, and other correspondences are not excluded. The correspondence relationship is agreed by the first communication node and the second communication node in advance.

In this embodiment, the first communication node determines the transmission mode of the transmission control information according to the manner in which the data corresponding to the control information is transmitted, and/or the manner in which the first communication node receives the data. Specifically, when the first link control information sent on the second link control resource is the CSI information, and is the CSI information of the second link beam training, the first link control resource is further according to the first communication node. The number of receive beams is determined, or further according to the number of antennas (or the number of antenna ports) of the second communication node and the number of antennas of the first communication node (or antenna ports) number),

12a is a schematic diagram of a first communication node determining a first link control resource according to a number of first communication node beams according to an embodiment of the present invention; as shown in FIG. 12a, the second communication node is trained on a second link beam. The second link beam training is sent in each time unit after the start, and the second communication node sends each second link transmit beam once in each time unit, and the first communication node determines its number according to the number of its own receive beams. In which time unit the second link beam training result is fed back, as shown in FIG. 12a, beam training is started in a time unit indexed by i, and the first communication node has three receiving beams, and the first communication node determines that it is in the first A link control resource is in a first link transmission domain of a time unit indexed as i+3, and the number of receive beams of the first communication node may be informed to the second communication node upon initial access. Or the first communication node reports its first link control information based on the contention mode in the first link transmission domain of the time unit indexed as i+3, where the first link control resource is a common first link control resource. Or the first communication node determines a time unit after the first link control resource is indexed as i+3, such as a time unit indexed as i+4, because the second communication node and the first communication node agree on the first link control The resource is on the first time unit after receiving the beam poll, so that the first communication node can find the second link optimal transmit and receive beams for a certain processing time.

此时第一通信节点根据自身的接收波束个数确定其对应的第一链路控制资源所在的时间单元，图12b是根据本发明实施例的第一通信节点根据第一通信节点波束个数确定第一链路控制资源的另一种示意图；如图12b所示，N1＝2,N3＝6，N2＝3，第二通信节点在每个时间单元中将每个第二链路发送波束发送2次，第一通信节点在索引为i+1的时间单元上就完成了所有接收波束的轮询，从而可以在索引为i+1的时间单元之后上报波束训练结果。In the second implementation manner of this embodiment, after the beam training is started, the second communication node sends N1 times for each transmission beam on the time unit with index i, if the second communication node specifies that it is to be in N2 time units. Each transmit beam is transmitted N3 times, where N3 is the maximum number of receive beams of the first communication node, then

At this time, the first communication node determines the time unit of the corresponding first link control resource according to the number of its own receiving beams, and FIG. 12b determines that the first communication node determines the number of beams according to the first communication node according to the embodiment of the present invention. Another schematic diagram of the first link control resource; as shown in FIG. 12b, N1=2, N3=6, N2=3, the second communication node transmits each second link transmit beam in each time unit. 2 times, the first communication node completes the polling of all the receiving beams on the time unit indexed as i+1, so that the beam training result can be reported after the time unit indexed as i+1.

In a third implementation manner of this embodiment, the second communication node will each in one time unit The second link transmitting beam is transmitted N3 times, wherein N3 is the maximum number of receiving beams of the first communication node, and the processing time for finding the optimal beam is different due to different number of receiving beams, and the first communication node may further be according to the second The number of transmit beams and the number of receive beams determine the corresponding first link control resources, so that the processing time of the user with a large number of receive beams is larger. Of course, the second communication node also needs to be based on the same rule. The CSI information of the first communication node is received on the first link control resource.

In the above embodiment, it is assumed that the second communication node and the first communication node scan only all the beam directions on one antenna. If the beam is trained, the second communication node and the first communication node need to scan the respective antennas (mainly radio frequency antennas). In the transmission direction and the reception direction, in order to find the optimal transmission beam combination (the beam including each transmit antenna in the combination), the optimal receive beam combination (including the receive beam of each receive antenna in the combination), The processing time for finding the beam combination increases with the number of transmitting antennas and the number of receiving antennas, and even exponentially increases, so the first communication node can further determine the first link control resource according to the number of transmitting antennas and the number of receiving antennas. For example, the first communication node and the second communication node agree that when the product of the number of transmitting antennas and the number of receiving antennas is greater than a threshold, the first link control resource is less than the threshold value in the time unit after the first time unit. On a time unit. Or the first communication node and the second communication node agree that when the number of transmitting antennas, the number of receiving antennas, the number of beams on each transmitting antenna, and the number of beams on each receiving antenna are greater than a threshold, The first link control resource is on the time unit after the first time unit, less than the threshold on the first time unit. Therefore, the number of beams can be increased, and users with more antennas have more processing time for finding the optimal beam.

Example 16

In this embodiment, in the first time unit where the second link data of the first communication node is located, the first link node assigns the first link to the first link transmission domain in the second link control domain. Transmitting the resource, the first communication node first determines the first link control resource corresponding to the second link data in its first link transmission resource.

13 is a schematic diagram of a first link control resource in a first link transmission domain corresponding to a first communication node according to an embodiment of the present invention; as shown in FIG. 13, the first communication node is in the first time unit shown At the same time, there is a second link transmission resource and a first link transmission resource, and the first communication node determines The first link control resource for transmitting control information is on its corresponding first link transmission resource, wherein the time-frequency resource occupied by the first link control resource in the first link transmission domain is according to the first communication node. The rules agreed with the second communication node are obtained.

In FIG. 13, the second link transmission resource occupied by the first communication node, the first link transmission resource, and the location of the first link control resource in the first link transmission resource are only examples, and other resources are not excluded. Possession.

Because the receiving manner adopted by the second communications node includes the receiving mode required by the second communications node in the first link transmission domain corresponding to the first communications node, the control information of the first communications node may be received.

Example 17

In this embodiment, the second communication node selects one or more transmission modes in a set of transmission modes, and notifies the first communication node of the selected transmission mode by signaling, and the first communication node sends the notification manner by using the notification manner. Control information. One of the transmission mode sets is a dual-issue agreement (for example, a set of transmission modes is formed by all possible transmission methods, or is agreed by the first communication node and the second communication node before, for example, in the beam training phase), specifically For example, a set of transmission modes includes four different resources, and the first communication node is signaled to transmit feedback information using a resource whose index is 0. The resources include transmitting beam resources, transmitting time resources, transmitting frequency domain resources, transmitting port resources, transmitting sequence resources, transmitting sector resources, and transmitting one or more of precoding matrix resources.

The control information includes one or more of the following: an acknowledgement ACK or a negative acknowledgement NACK information of the data corresponding to the control information; channel state CSI information; resource request information; random access request information. The CSI information includes transmission mode selection information, and/or reception mode selection information. For example, the second communication node sends a preferred transmission mode of the second communication node in the first communication link received by the first communication node, and/or a preferred reception mode of the first communication node, or is sent by the first communication node and the second communication node. a preferred receiving mode of the second communication node in the second communication link received by the communication node, and/or a preferred receiving mode, wherein the preferred sending mode indicates that one or more transmitting modes are selected from a set of sending modes, that is, the sending mode is selected. information. Preferably, the receiving mode indicates that one or more receiving modes are selected from one set of transmission modes.

Example 18

In this embodiment, the control information corresponding to the data signal in the nth time unit is sent in the n+K1 time unit, but the time unit that satisfies the following features is not included in the calculation of the K1 time units: The time unit does not include the first link transmission domain, and the time unit does not include the first link control domain.

Specifically, the signal is the PDSCH, and the control control information is UCI as an example. For example, the terminal obtains the K1 value by dynamic signaling, where the K1 belongs to {0-C}, and the n-th time unit is included after the n-time unit, if the time unit satisfies at least one of the following features The time unit does not include an uplink transmission domain, and the time unit does not include an uplink control domain. For example, if the time unit is a pure downlink time unit through high-level signaling or a predetermined rule, the time units are skipped when the K1 is calculated. For example, the time units are used for the following information transmission: synchronization signal scanning time unit, measurement reference The signal scanning time unit, the scanning time unit of the system message, the scanning transmission of the broadcast message, or the high-level configuration of these time units are pure downlink time units.

Specifically, as shown in FIG. 14a to FIG. 14b, wherein C=7 is assumed, in FIG. 14a, since the range of K1 is 0-7, the PDCH corresponding to the PDSCH of the nth time unit (such as a slot or a subframe) is (for example) Including ACK/NACK information) can only be scheduled in the nth to n+3th time units. If the pure downlink subframe is not counted, then C=7, the nth time unit (such as slot or subframe) The PUCCH corresponding to the PDSCH (such as including ACK/NACK information therein) may be scheduled in the nth time to the n+3th time unit or in the n+8th to nthth 11th time units, thereby making the same The signaling overhead of K1 increases the flexibility of scheduling.

In the foregoing embodiment, K1 is obtained by dynamic signaling, where K1 is also a mode of m+k, where m is a semi-static signaling or a fixed value, and k is dynamic signaling. In this case, the first method is calculation. K1 ignores the above-mentioned time unit that satisfies the condition. The second way is to ignore the above-mentioned time unit that satisfies the condition only when calculating k. The third way is to ignore the above-mentioned time unit that satisfies the condition only when calculating m.

For the above-mentioned time unit that satisfies the condition, the above embodiment is an agreed or semi-static notification, and the present example does not exclude that the time unit is included after the time unit n. If the dynamic signaling obtains that the time unit satisfies the above condition, the above K1 is calculated. , or m, or k, skip these time units.
