Description

A method, device and system for transmitting uplink control information

technical field

The present invention relates to the technical field of wireless communication, and in particular, to a method, device and system for transmitting uplink control information.

Background technique

In a Time Division Duplexing (TDD) system of Long Term Evolution (LTE), each radio frame includes 10 subframes, each subframe is 1 millisecond in length, and different subframes are used for uplink and downlink respectively. In order to adapt to different application scenarios, the LTE TDD system can use different uplink and downlink subframe ratios according to service conditions to meet different uplink and downlink asymmetric service requirements. However, in an ultra-dense network, the density of base stations is very high, and each small base station serves a small number of users. Therefore, the proportion of uplink and downlink traffic loads in each cell changes rapidly, and the static or semi-static uplink and downlink subframes are allocated. The ratio of the uplink and downlink traffic loads cannot be well matched, resulting in the inability of resources to be effectively utilized.

The dynamic and flexible subframe allocation can better solve the above problems, that is, by configuring the dynamic and flexible subframe allocation, the uplink and downlink service load ratios can be matched faster and more accurately. However, the dynamic and flexible subframe ratio also brings about a more complicated hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) timing design. Since the ratio of uplink and downlink is not fixed, user equipment (User Equipment, UE) needs to wait for the appearance of an uplink subframe when feeding back uplink acknowledgement (Acknowledgement, ACK)/Negative Acknowledgment (NACK) The appearance of the frame is uncertain, so the waiting time of the UE is also uncertain, which causes the UE to need more storage space for buffering data, or the downlink transmission is affected because the ACK/NACK cannot be reported in time.

In addition, if adjacent cells use different subframe configurations, severe uplink and downlink interference may occur on the subframes with different configurations. As shown in Figure 1, D represents a downlink subframe, and U represents an uplink subframe. When the subframe configurations of the two cells are different, taking subframe 3 in Figure 1 as an example, the subframe of cell 1 has 3 uplink subframes. Subframe 3 of cell 2 is a downlink subframe, so the downlink signal of cell 2 will cause serious interference to the uplink signal of cell 1 .

In order to solve the problems existing in the prior art, an embodiment of the present invention provides a transmission scheme for uplink control information. In this technical solution, the user equipment determines the subframe configuration information, and determines N first subframes from the subframe set indicated by the subframe configuration information, and the first subframe is in the subframe set indicated by the subframe configuration information. The flexible subframes and/or uplink subframes are sent, and then the uplink control information is sent on the first subframe. Through the technical solutions of the embodiments of the present invention, the uplink control information is fixed and sent on the first subframe, which simplifies the HARQ sequence design, and when two adjacent cells use different subframe configurations, the two cells send the uplink control information are the first subframe, so there is no interference between uplink and downlink.

The “base station” mentioned in the embodiment of the present invention may be, but is not limited to, any of the following: a base station corresponding to a cell, an enhanced base station (eNodeB), a micro base station, a home base station, and a Remote Radio Unit (Remote Radio Unit). , RRU), a remote radio head (Remote Radio Head, RRH), a relay node, and a set formed by the above entities.

The embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention. Also, the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.

An embodiment of the present invention provides a method for transmitting uplink control information, as shown in FIG. 2 , which is a flow chart of the implementation of the method. The execution body of the method may be a UE, and specifically includes the following steps:

Step 21, the UE determines subframe configuration information, wherein the subframe configuration information includes: location information of downlink subframes, flexible subframes and/or uplink subframes in the subframe set.

The flexible subframe may be an uplink subframe, a downlink subframe, or a mixed uplink and downlink subframe (ie, the flexible subframe contains both downlink information and uplink information).

Specifically, the UE may determine the subframe configuration information according to the preset first configuration information, or may determine the subframe configuration information according to the first indication information sent by the base station.

Optionally, the first indication information may be sent by the base station in a broadcast or unicast manner through high-layer signaling or dynamic signaling.

For example, a subframe set contains 5 subframes, and the base station can configure these 5 subframes into a DXXXU format, where D represents a downlink subframe, X represents a flexible subframe, and U represents an uplink subframe. At this time, the UE is in the first The downlink signal sent by the base station is received in subframes, the uplink signal is sent in the fifth subframe, and the downlink signal is received or the uplink signal is sent in the second, third, and fourth subframes; or, the base station can configure these five subframes as In the format of DXXXX, at this time, the UE receives the downlink signal sent by the base station in the first subframe, and receives the downlink signal or sends the uplink signal in the second, third, fourth, and fifth subframes.

Step 22, the UE determines N first subframes from the subframe set indicated by the subframe configuration information; wherein, the first subframe is a flexible subframe and/or a flexible subframe in the subframe set indicated by the subframe configuration information Uplink subframe; wherein, N is a positive integer.

Specifically, the UE may determine N first subframes from the subframe set indicated by the subframe configuration information according to the preset second configuration information, or may determine the N first subframes from the subframe set according to the second indication information sent by the base station. In the subframe set indicated by the configuration information, N first subframes are determined.

Optionally, the second indication information may be sent by the base station in a broadcast or unicast manner through higher layer signaling.

Optionally, the second indication information may be to indicate the first subframe in the subframe set by adopting a bit map (bit map). For example, a subframe set contains 5 subframes, the second indication information can be configured in the form of 00001 to indicate that the fifth subframe in the subframe set is the first subframe, or the second indication information can be configured as 00101 form, which is used to indicate that the third subframe and the fifth subframe in the subframe set are the first subframe.

In addition, the value of N can be determined in one of the following ways:

1. The value of N is determined according to the load of the uplink control information.

Specifically, the corresponding relationship between the load of the uplink control information and N may be preset, and after the load of the uplink control information is determined, the corresponding N value is also determined.

The corresponding relationship between the load of the uplink control information and N can be set according to the following rules:

If the load of the uplink control information is heavy, the value of N is large; if the load of the uplink control information is light, the value of N is small. During specific implementation, different intervals may be set for the load of the uplink control information, and each interval corresponds to an N value.

2. The value of N is determined according to the required delay of the service of the UE.

Specifically, the corresponding relationship between the required delay of the service of the UE and N may be preset, and after the required delay of the service of the UE is determined, the corresponding N value is also determined.

The corresponding relationship between the required delay of the service of the UE and N can be set according to the following rules:

If the required delay of the service of the UE is small, the value of N is relatively large; if the required delay of the service of the UE is relatively large, the value of N is relatively small. During specific implementation, different intervals may be set for the required delay of the service of the UE, and each interval corresponds to a value of N.

In addition, when the value of N is determined according to the required delay of the service of the UE, the positions of the N first subframes in the subframe set indicated by the subframe configuration information can be determined as follows:

When the determined N is greater than the preset value, the positions of the N first subframes in the subframe set indicated by the subframe configuration information are discontinuous.

Optionally, when the determined N is not greater than the preset data, the positions of the N first subframes in the subframe set indicated by the subframe configuration information may be continuous or discontinuous.

For example, if a subframe set contains 5 subframes, the UE may predefine the last N subframes in the subframe set as the first subframe; or the base station may configure the last N of the 5 subframes as the first subframe; or The base station may configure the third subframe and the fifth subframe in the 5 subframes as the first subframe.

Step 23, the UE sends uplink control information on the determined first subframe.

Wherein, the uplink control information may include at least one of the following:

ACK/NACK indication information, channel state information (Channel State Information, CSI), scheduling request information (Schedule Request, SR), sounding reference signal, and random access channel corresponding to the downlink data.

When the uplink control information is the ACK/NACK indication information corresponding to the downlink data, and the downlink data is sent in subframe k, the uplink control information is sent in the first subframe, which may specifically include:

The uplink control information is sent on the first subframe that occurs first after subframe k+m; where k and m are positive integers.

That is to say, if the subframe number corresponding to the first subframe in which the ACK/NACK indication information is sent is i, then the ACK/NACK indication information sent on the first subframe corresponds to a certain subframe before the i-mth subframe or Downlink data sent on certain downlink subframes or flexible subframes used for sending downlink data. Wherein, m is a positive integer, such as m=4.

In addition, when the first subframe includes an uplink subframe, the first subframe serving as an uplink subframe can be used by the UE and other UEs in the cell where the UE is located to transmit uplink data in addition to the uplink control information transmitted by the UE .

When the first subframe includes a flexible subframe, the first subframe, which is a flexible subframe, can be used by the UE and other UEs in the cell where the UE is located to transmit uplink data in addition to the uplink control information by the UE; or When the first subframe, which is a flexible subframe, is not used by any UE to transmit uplink control information, it can also be used by the base station to transmit downlink data; or the first subframe, which is a flexible subframe, can be used by the UE to transmit uplink control information in addition to transmitting uplink control information. In addition to the information, it can also be used by the UE and other UEs in the cell where the UE is located to receive downlink information.

Through the technical solutions of the embodiments of the present invention, the uplink control information is fixed and sent on the first subframe, which simplifies the HARQ sequence design, and when two adjacent cells use different subframe configurations, the two cells send the uplink control information are the first subframe, so there is no interference between uplink and downlink.

Based on the same inventive concept, an embodiment of the present invention also provides a method for transmitting uplink control information, as shown in FIG. 3 , which is a flow chart of the implementation of the method. The execution subject of the method may be a base station, which specifically includes the following steps:

Step 31, the base station determines subframe configuration information, wherein the subframe configuration information includes: location information of downlink subframes, flexible subframes and/or uplink subframes in the subframe set.

The flexible subframe may be an uplink subframe, a downlink subframe, or a mixed uplink and downlink subframe (ie, the flexible subframe contains both downlink information and uplink information).

Specifically, the base station may determine the subframe configuration information according to the preset third configuration information or according to the uplink and downlink service load or according to the required time delay of the service.

Combined with the above-mentioned transmission method of uplink control information implemented by the UE side, if the UE determines the subframe configuration information according to the preconfigured first configuration information, the base station determines the subframe configuration information according to the third indication information sent by the UE; if The UE determines the subframe configuration information according to the first indication information sent by the base station. After determining the subframe configuration information, the base station may further include: the base station sends the first indication information to the user equipment, so that the user equipment can use the first indication information according to the first indication information. , and determine the subframe configuration information.

Step 32, the base station determines N first subframes from the subframe set indicated by the subframe configuration information; wherein the first subframe is a flexible subframe and/or a flexible subframe in the subframe set indicated by the subframe configuration information Uplink subframe; wherein, N is a positive integer.

Specifically, the base station determines N first subframes from the subframe set indicated by the subframe configuration information according to the preset fourth configuration information or according to the load of the uplink and downlink control information or according to the required delay of the service. .

Optionally, the fourth indication information may be to indicate the first subframe in the subframe set by adopting a bit map (bit map). For example, a subframe set includes 5 subframes, and the fourth indication information can be configured in the form of 00001 to indicate that the fifth subframe in the subframe set is the first subframe, or the second indication information can be configured as 00101 form, which is used to indicate that the third subframe and the fifth subframe in the subframe set are the first subframe.

In combination with the method for transmitting uplink control information implemented by the UE side, if the UE determines the N first subframes according to the preconfigured second configuration information, the base station determines the N first subframes according to the fourth indication information sent by the UE. Subframe; if the UE determines N first subframes according to the second indication information sent by the base station, then the base station may further include after determining the N first subframes from the subframe set indicated by the subframe configuration information: The base station sends the second indication information to the user equipment, so that the user equipment can determine N first subframes from the subframe set indicated by the subframe configuration information according to the second indication information.

In addition, the value of N is the same as the implementation process of the value of N in the method for transmitting uplink control information implemented by the UE side, which is not repeated here.

Step 33, the base station receives the uplink control information sent by the UE in the determined first subframe.

Wherein, the uplink control information may include at least one of the following:

ACK/NACK indication information, CSI, SR, sounding reference signal and random access channel corresponding to downlink data.

Through the technical solutions of the embodiments of the present invention, the uplink control information is fixed and sent on the first subframe, which simplifies the HARQ sequence design, and when two adjacent cells use different subframe configurations, the two cells send the uplink control information are the first subframe, so there is no interference between uplink and downlink.

In order to better understand the embodiments of the present invention, the specific implementation process of the embodiments of the present invention will be described below with reference to specific implementations.

Assuming that one subframe set includes 5 subframes, the UE determines that the subframe is configured as DXXXU by means of pre-definition or base station configuration (for the specific meaning, refer to the above embodiments of the present invention). In the scenario of FIG. 1 , there are two cells, and the specific uplink and downlink subframe configurations of the cell 1 and the cell 2 in a certain period of time are shown in FIG. 4 . The UE determines that the last subframe in the subframe set is the first subframe by means of pre-definition or base station configuration, and the uplink control information sent by the UE on the first subframe is the ACK/NACK indication information corresponding to the downlink data.

As shown in FIG. 5 and FIG. 6 , they are a schematic diagram of a transmission method of uplink control information provided by an embodiment of the present invention and a schematic diagram of a transmission method of uplink control information in the prior art, respectively.

Referring to FIG. 5 , according to the method of the embodiment of the present invention, the ACK/NACK indication information corresponding to the first three downlink subframes of the two cells in FIG. 5 is sent on the first subframe indicated by the solid line. At this time, the subframes in which the two cells send the uplink control information are the same, and the interference between uplink and downlink shown in FIG. 1 does not exist in the subframes.

Referring to FIG. 6, according to the method in the prior art, the subframes in which the two cells send uplink control information are the subframes indicated by the dotted lines. In this case, the subframes in which the two cells send uplink control information may be different, and there may be a The uplink control information is interfered by the downlink data of another cell (such as the subframe indicated by the arrow).

Therefore, the technical solutions provided by the embodiments of the present invention can prevent the uplink control channel from being interfered by the downlink data from adjacent cells.

In addition, compared with existing solutions, the HARQ design of the present invention is also simpler. Specifically, in the present invention, the number of HARQ processes can be fixed, thereby simplifying the protocol and simplifying the implementation complexity of the terminal. In this example, assuming that m=4 in the above embodiment, the number of HARQ processes may be fixed at 10. Generally, assuming that the subframe set includes L subframes, and assuming that the last subframe is the first subframe, the number of HARQ processes may be fixed to L+2*M-3.

Therefore, the implementation of the device and the system can refer to the implementation of the method, and the repetition will not be repeated.
