Description

Method and device for transmitting PUCCH

Technical field

The present application relates to the field of mobile communication technologies, and in particular, to a PUCCH transmission method and device.

Background technique

At present, when Physical Uplink Control Channel (PUCCH) and Sounding Reference Signal (SRS) are multiplexed, that is, the terminal sends PUCCH and SRS in the same subframe, and the last symbol of the subframe is used for Send SRS, other symbols can be used to send PUCCH. And when the subframe is a cell-level subframe, even if the terminal does not send an SRS, the last symbol of the subframe is not used to send a PUCCH, because other terminals may send SRS.

With the development of wireless communication requirements and the increase of various mobile operator services, the overall demand for wireless communication capacity and the load of services are rapidly increasing. Considering the high cost of base station encryption and the limited spectrum bandwidth below 6G, it is becoming increasingly urgent to increase the spectral efficiency of existing networks. Therefore, Multiple-Input Multiple-Output (MIMO) is a key role as a key technology to improve spectrum efficiency. In addition, SRS is a key factor to improve downlink MIMO performance. Therefore, further SRS capacity improvement techniques need to be considered. For example, in a normal uplink subframe, SRS transmission of more than one symbol can be supported, thereby improving the capacity and coverage of the SRS.

However, when the number of symbols allocated for sending SRS increases, SRS and PUCCH conflicts will result.

Some or some symbols, that is, some symbols of the first time slot can be used. Specifically, this application does not limit this.

The PUCCH transmission method provided in this application will be specifically described below with reference to the specific example shown in FIG. 7 and FIG. 2 (a) to FIG. 6 (b).

As shown in FIG. 7, a PUCCH transmission method provided by the present application. The method includes the following steps:

Step 701: The access network device sends configuration information to the terminal. Accordingly, the terminal can receive the configuration information. The configuration information is used to indicate a time resource for sending the SRS.

Optionally, the time resource for sending the SRS may refer to a time resource for sending the SRS, or a time resource occupied by the SRS, or an available time resource for sending the SRS.

Step 702: The terminal determines a resource for sending a PUCCH according to the configuration information, and sends a PUCCH on the resource.

As an implementation manner, the terminal may determine a resource for sending a PUCCH according to the configuration information.

As another implementation manner, the terminal may further determine a resource for sending a PUCCH according to the configuration information and a preset rule.

As another implementation manner, the terminal may also determine a resource for sending a PUCCH according to the configuration information and the capability of the terminal.

As another implementation manner, the terminal may further determine a resource for sending a PUCCH according to the configuration information, a preset rule, and the capability of the terminal.

In specific implementation, optionally, the configuration information in step 701 may also be used to indicate a frequency resource for sending SRS.

In specific implementation, optionally, in step 702 above, the terminal may also send an SRS on the resource indicated by the configuration information.

As an implementation manner, the access network device may send the above configuration information through high-level signaling or physical layer signaling. High-level signaling may refer to other high-level signaling such as radio resource control (RRC) signaling or medium access control (MAC) signaling. The physical layer signaling may be other physical layer signaling such as Downlink Control Information (DCI). Specifically, this application does not limit this.

In specific implementation, the above configuration information may include cell-level configuration information and / or terminal-level configuration information. Among them, the cell-level configuration information refers to all terminals in the cell, and the terminal-level configuration information refers to only the terminals. The cell-level configuration information may be sent through public information, and the terminal-level configuration information may be sent through private information.

In the embodiment of the present application, the time resources occupied by the SRS may refer to the time resources occupied by the cell-level SRS, or may refer to the time resources occupied by the terminal-level SRS. The time resource may refer to a subframe resource, a time slot resource, or a symbol resource.

The following describes the PUCCH and / or SRS transmission method in different scenarios.

Case 1: The time resource for sending SRS indicated by the configuration information is an even-numbered time slot.

In this case, the processing of the PUCCH and SRS conflicts may include one or more of the following rules:

Rule 1: PUCCH only occupies odd-numbered time slots (as shown in Figure 2 (a)).

Rule 2: PUCCH occupies the entire subframe (as shown in Fig. 3 (a)).

The time resource for sending the SRS indicated by the configuration information may be a cell-level SRS resource or a terminal-level SRS resource. In the following, the time resource for sending SRS indicated by the configuration information refers to the cell-level SRS resource for example.

Optionally, the specific PUCCH transmission method may include one or more of the following methods:

Method 1: When the cell-level SRS resource is indicated as an even-numbered time slot, the PUCCH can be transmitted only in the odd-numbered time slot.

This method can ensure that the resources of SRS and PUCCH do not overlap, and both SRS and PUCCH can be transmitted, ensuring the transmission performance of both.

However, compared to the PUCCH transmission of the entire subframe, the PUCCH of a single slot will cause the performance of the PUCCH to deteriorate, and the PUCCH coverage performance can be improved by other sequence enhancement or transmission enhancement.

Optionally, in this method, even if the terminal does not transmit SRS in this subframe, or transmits SRS only on one or more symbols (not the entire even-numbered time slot) in the even-numbered time slot, for rule 1, the The PUCCH of the terminal also only occupies odd-numbered time slots.

Method 2: When the cell-level SRS resource is indicated as an even-numbered time slot, and the terminal does not transmit SRS in the even-numbered time slot, the PUCCH can be transmitted in the entire subframe. If the terminal transmits SRS in the even-numbered time slot, the PUCCH is transmitted only in the odd-numbered time slot.

In this method, because the terminal does not have SRS transmission, there is no need to consider the limitation of the single carrier characteristic, and the PUCCH transmission in the entire subframe can guarantee the coverage performance of the PUCCH.

When the terminal has SRS transmission, the single carrier characteristic of the terminal is considered at this time, and the PUCCH is not transmitted in the place where the SRS resource is transmitted, so the PUCCH can be transmitted only in odd-numbered time slots.

Optionally, in this method, even if the terminal transmits SRS on only one or more symbols (not the entire even-numbered time slot) in the even-numbered time slot, the PUCCH of the terminal only occupies the odd-numbered time slot.

That is, the PUCCH of some terminals is transmitted in the entire subframe, and the PUCCH of some terminals is transmitted in odd-numbered time slots, but for one time slot, the orthogonality of the PUCCH can be guaranteed.

Method 3: When the cell-level SRS resource is indicated as an even-numbered time slot, and the terminal does not transmit SRS in this time slot, the PUCCH can be transmitted in the entire subframe. If the terminal transmits an SRS in this time slot, the PUCCH is transmitted on consecutive symbols other than the SRS.

This method can ensure the maximum PUCCH coverage performance and meet the requirements of single carrier characteristics, but the orthogonality of PUCCH of multiple terminals may be destroyed.

Method 4: When the cell-level SRS resource is indicated as an even-numbered time slot, the resource for PUCCH transmission is determined according to the terminal capability.

This method prioritizes the coverage and performance of PUCCH and reduces the impact of PUCCH.

Optionally, the capability of the terminal may refer to whether the terminal supports simultaneous transmission of SRS and PUCCH, or whether the terminal can relax the restriction of a single carrier, or it may refer to whether the terminal supports priority for transmitting SRS and PUCCH. Or the capability of the terminal in this application may also be the capability of other terminals, which is not limited in this application.

For example, if the terminal supports simultaneous transmission of SRS and PUCCH (or relaxes the restriction of single carrier), the PUCCH can be transmitted in the entire subframe, even if the terminal transmits SRS on even-numbered time slots at this time.

For example, if the terminal does not support simultaneous transmission of SRS and PUCCH (strict single-carrier restrictions), the PUCCH may only be transmitted on odd-numbered time slots.

For example, if the terminal supports high priority for transmitting SRS, the terminal can guarantee to transmit SRS first. If the terminal supports high priority for transmitting PUCCH, the terminal may transmit only PUCCH without transmitting SRS.

As an implementation manner, the access network device may indicate the terminal priority.

As an implementation manner, it may be a rule adopted by the access network device to instruct the terminal or a resource transmitted by the PUCCH. For example, the access network device may indicate whether the terminal uses a slot-level PUCCH or a subframe-level PUCCH.

Compared with the prior art, a rule for transmission conflict between PUCCH and SRS is designed, which not only guarantees the coverage of SRS, but also avoids the impact on PUCCH transmission and improves the signal transmission performance.

In the second case, the time resource for sending the SRS indicated by the configuration information is an odd-numbered time slot.

Rule 1: PUCCH only occupies even-numbered time slots (as shown in Figure 2 (b)).

Rule 2: PUCCH occupies the entire subframe, and SRS is discarded (as shown in FIG. 3 (c)).

Rule 3: PUCCH occupies the entire subframe except the last symbol (as shown in FIG. 3 (e)).

Optionally, the specific PUCCH transmission method may be one or more of the following methods:

Method 1: When the cell-level SRS resources are indicated as odd-numbered time slots, the PUCCH can be transmitted only in even-numbered time slots.

This method can ensure that the resources of SRS and PUCCH do not overlap, and both SRS and PUCCH can be transmitted, ensuring the transmission performance of both. However, compared to the PUCCH transmission of the entire subframe, the PUCCH of a single slot will cause the performance of the PUCCH to deteriorate, and the PUCCH coverage performance can be improved by other sequence enhancement or transmission enhancement.

Optionally, in this method, even if the terminal does not transmit SRS in this subframe, or transmits SRS only on one or more symbols in odd-numbered time slots (not the entire odd-numbered time slot), PUCCH is only only on even numbers. Transmission in numbered time slots.

Method 2: When the cell-level SRS resource is indicated as an odd-numbered time slot, and the terminal does not transmit SRS in this time slot, the PUCCH can be transmitted in the entire subframe (or in a symbol other than the last symbol of the subframe) transmission). If the terminal transmits SRS in this time slot, the PUCCH is transmitted only in even-numbered time slots.

When the PUCCH is transmitted in resources other than the last symbol in the entire subframe, it can be compatible with the existing PUCCH transmission mode in long term evolution (LTE), and better ensure the orthogonality of the PUCCH.

When the terminal has SRS transmission, the single-carrier characteristics of the terminal are considered at this time, and the PUCCH is not transmitted where the SRS resources are transmitted, so the PUCCH can be transmitted only in even-numbered time slots.

Optionally, in this method, even if the terminal transmits SRS on only one or more symbols (not the entire odd-numbered time slot) in the odd-numbered time slot, the PUCCH of the terminal only occupies the even-numbered time slot.

Method 3: When the cell-level SRS resource is indicated as an odd-numbered time slot, and the terminal does not transmit SRS in this time slot, the PUCCH can be transmitted in the entire subframe (or in a symbol other than the last symbol of the subframe) transmission). If the terminal transmits an SRS in this time slot, the PUCCH is transmitted on consecutive symbols other than the SRS.

Method 4: When the cell-level SRS resources are indicated as odd-numbered time slots, the resources for PUCCH transmission are determined according to the capabilities of the terminal.

The capability of the terminal may refer to whether the terminal supports simultaneous transmission of SRS and PUCCH, or whether the terminal can relax the restriction of a single carrier, or it may refer to whether the terminal supports priority for transmitting SRS and PUCCH.

For example, if the terminal supports simultaneous transmission of SRS and PUCCH (or relaxes the restriction of single carrier), the PUCCH can be transmitted in the entire subframe (or in a symbol other than the last symbol of the subframe), even if the terminal is in an odd SRS is transmitted on numbered time slots.

For example, if the terminal does not support the simultaneous transmission of SRS and PUCCH (strict single-carrier restrictions), the PUCCH can only be transmitted on even-numbered time slots.

In case three, the time resource for sending the SRS indicated by the configuration information is the entire subframe.

Rule 1: PUCCH occupies the entire subframe, SRS (as shown in Figure 4 (b))

Rule 2: PUCCH occupies the entire subframe except the last symbol (as shown in FIG. 4 (a)).

Method 1: When the cell-level SRS resource is indicated as the entire subframe, the PUCCH may transmit or occupy symbols other than the last symbol in the subframe in the entire subframe.

At this time, if the terminal transmits SRS in this subframe, it can use SRS to preferentially guarantee the transmission of PUCCH.

Alternatively, the terminal may transmit the SRS only on the last symbol, and the PUCCH may transmit on symbols other than the last symbol in the subframe.

Method 2: When the cell-level SRS indicates the entire subframe and the terminal-level SRS resource indicates the odd-numbered time slot, the PUCCH can be transmitted in the even-numbered time slot (or in a symbol other than the last symbol of the subframe) Transfer). When the cell-level SRS indicates the entire subframe, and the terminal-level SRS resource indicates the even-numbered time slot, the PUCCH can be transmitted in the odd-numbered time slot (or in the odd-numbered time slot except the last symbol of the subframe) Transfer). When the terminal is not transmitting the SRS in this subframe, the PUCCH may be transmitted in the entire subframe (or in a symbol other than the last symbol of the subframe).

When the PUCCH is transmitted in resources other than the last symbol of the entire subframe, it can be compatible with the existing PUCCH transmission mode in LTE, and better guarantee the orthogonality of the PUCCH.

When the terminal has SRS transmission, the single carrier characteristic of the terminal is considered at this time, and the PUCCH is not transmitted where the SRS resources are transmitted, so the PUCCH can be transmitted only in even-numbered time slots or in even-numbered time slots.

That is, the PUCCH of some terminals is transmitted in the entire subframe, while the PUCCH of some terminals is transmitted in odd-numbered time slots, and the PUCCH of some terminals is transmitted in even-numbered time slots. Guarantee the orthogonality of PUCCH.

Method 3: When the terminal does not transmit SRS in this time slot, the PUCCH may be transmitted in the entire subframe (or in a symbol other than the last symbol of the subframe). If the terminal transmits an SRS in this time slot, the PUCCH is transmitted on consecutive symbols other than the SRS.

The above SRS resource may refer to the SRS resource transmitted by the terminal transmitted by the PUCCH. If the last symbol of the terminal does not transmit SRS, the PUCCH may occupy the entire subframe. If the last symbol of the terminal transmits SRS, the PUCCH may occupy the last The entire subframe outside of one symbol

Method 4: When the cell-level SRS resource is indicated as the entire subframe, the resource for PUCCH transmission is determined according to the capability of the terminal.

For example, if the terminal supports simultaneous transmission of SRS and PUCCH (or relaxes the restriction of single carrier), the PUCCH can be transmitted in the entire subframe (or in a symbol other than the last symbol of the subframe), even if the terminal is in the sub-frame at this time. SRS is transmitted on some symbols in the frame.

For example, if the terminal does not support simultaneous transmission of SRS and PUCCH (strict single-carrier restrictions), the PUCCH can be transmitted in the entire subframe (or even-numbered time slot transmission, or odd-numbered time slot transmission), and SRS is discarded or the SRS is transmitted on different time slots or symbols.

In case four, the time resource for sending the SRS indicated by the configuration information is an even-numbered time slot and the last symbol in the subframe.

Rule 1: PUCCH occupies the entire odd-numbered time slot (as shown in FIG. 5 (a)).

Rule 2: PUCCH occupies the entire odd-numbered time slot except the last symbol (as shown in FIG. 5 (b)).

Rule 3: PUCCH occupies the entire subframe (as shown in Fig. 6 (a)).

Rule 4: PUCCH occupies the entire subframe except the last symbol (as shown in FIG. 6 (b)).

Specifically, for example, it may be determined that the PUCCH only occupies odd-numbered time slots or the entire subframe or the entire subframe except the last symbol according to whether the terminal transmits the SRS.

Specifically, for example, it can be determined according to the capabilities of the terminal whether it is rule 1, or rule 2, or rule 3, or rule 4.

Method 1: When the cell-level SRS resource is indicated as an even-numbered time slot and the last symbol in the subframe, the PUCCH can be transmitted only in the odd-numbered time slot (or the PUCCH occupies the entire odd-numbered time slot except the last symbol) .

Optionally, in this method, even if the terminal does not transmit SRS in this subframe, or only transmits SRS on one or more symbols in an even-numbered time slot (not the entire even-numbered time slot), the PUCCH is only limited to Transmission in odd-numbered time slots (or PUCCH occupies the entire odd-numbered time slot except the last symbol).

Method 2: When the cell-level SRS resource is indicated as an even-numbered time slot and the last symbol in a subframe, and the terminal does not transmit SRS in this time slot, the PUCCH can be transmitted in the entire subframe. If the terminal transmits SRS in this time slot, the PUCCH is transmitted only in odd-numbered time slots.

Optionally, in this method, even if the terminal transmits SRS only on one or more symbols (not the entire even-numbered time slot) in the even-numbered time slot, the PUCCH of the terminal only occupies the odd-numbered time slot (or the PUCCH accounts for The entire odd-numbered time slot except the last symbol).

Method 3: When the cell-level SRS resource is indicated as an even-numbered time slot and the last symbol in a subframe, and the terminal does not transmit SRS in this time slot, the PUCCH can be transmitted in the entire subframe. If the terminal transmits an SRS in this time slot, the PUCCH is transmitted on consecutive symbols other than the SRS.

Method 4: When the cell-level SRS resource is indicated as an even-numbered time slot and the last symbol in a subframe, a resource for PUCCH transmission is determined according to the capability of the terminal.

This method prioritizes the coverage and performance of PUCCH and reduces the impact of PUCCH

For example, if the terminal supports simultaneous transmission of SRS and PUCCH (or relaxes the restriction of a single carrier), the PUCCH can be transmitted in the entire subframe, even if the terminal transmits SRS on even-numbered time slots at this time.

For example, if the terminal does not support the simultaneous transmission of SRS and PUCCH (strict single-carrier restrictions), the PUCCH can only be transmitted on odd-numbered time slots.
