Detailed Description
In order to make the purpose, technical scheme and advantages of the present application clearer, embodiments of the present application provide an uplink control information processing method and apparatus, where when user equipment sends HARQ ACK/NACK, the HARQ ACK/NACK is bundled and combined with an SR to obtain bundled ACK/NACK and SR multiplexing information, and thus the multiplexing information is carried in uplink control information by an uplink control channel and sent to base station equipment, so that resource overhead of the uplink control channel is effectively reduced, and the purpose of improving the usage rate of uplink control resources is achieved, and system requirements of a 5G network are met at the same time.
Various embodiments of the present application will be described in further detail with reference to the drawings attached hereto, and it should be understood that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a flowchart illustrating an uplink control information processing method according to an embodiment of the present application. The method may be as follows. An execution main body of the embodiment of the application is User Equipment (UE). The type of user equipment is not particularly limited herein.
Step 101: and the user equipment performs binding processing on the hybrid automatic repeat request acknowledgement/non-acknowledgement information HARQ ACK/NACK corresponding to the downlink data to obtain bound bundled ACK/NACK.
In the embodiment of the application, when receiving downlink data sent by base station equipment, user equipment determines whether the base station equipment needs to resend the downlink data, and if it is determined that the downlink data does not need to be resent by the base station equipment, the user equipment determines to confirm the downlink data, namely to feed back HARQ ACK, so that when receiving the HARQ ACK, the base station equipment determines to send new downlink data to the user equipment; if it is determined that the base station equipment needs to retransmit the downlink data, it is determined that the downlink data is not acknowledged, that is, HARQ NACK is fed back, so that the base station equipment determines to retransmit the downlink data to the user equipment when receiving the HARQ NACK.
In order to reduce the system overhead, the user equipment performs bundling processing on the HARQ ACK/NACK of the downlink data. Specifically, a plurality of downlink data of the same serving cell are subjected to logical AND (local AND) operation with respect to ACK/NACK of the same code word, AND finally ACK/NACK information of 1bit (non-space division multiplexing, using PUCCH format 1a) or 2bit (space division multiplexing, using PUCCH format 1b) is obtained. That is, 2-bit HARQ ACK/NACK can be bundled to obtain 1-bit ACK/NACK information.
Step 102: and the user equipment combines the bundled ACK/NACK and the scheduling request SR information to obtain multiplexing information of the bundled ACK/NACK and the SR.
The multiplexing information comprises one of bundled ACK + positive SR, bundled NACK + positive SR, bundled ACK + negative SR, and bundled NACK + negative SR.
In the embodiment of the application, in order to save system resource overhead, a mode of multiplex transmission of harq ack/NACK and SR is adopted, so that the user equipment further needs to further judge whether the base station equipment needs to allocate scheduling resources for the user equipment, and if the base station equipment needs to allocate scheduling resources for the user equipment, the user equipment determines to transmit a positive SR; and if the base station equipment is not required to allocate scheduling resources for the base station equipment, determining to transmit the negative SR.
After the user equipment obtains the scheduling request SR information, combining the bundled ACK/NACK and the scheduling request SR information to obtain multiplexing information of the bundled ACK/NACK and the SR:
bundled ACK+positive SR、bundled NACK+positive SR、bundled ACK+negative SR、bundled NACK+negative SR。
in other words, the resulting multiplexing information is: bundled ACK + positive SR, bundled NACK + positive SR, bundled ACK, and bundled NACK.
It should be noted that, the bundled ACK + positive SR and the bundled NACK + positive SR indicate that SR information is simultaneously transmitted when ACK/NACK information is transmitted, which may be referred to as ACK/NACK and SR true multiplexing; the bundled ACK + negative SR and the bundled NACK + negative SR indicate that SR information is not sent when ACK/NACK information is sent, which may be referred to as ACK/NACK and SR pseudo multiplexing.
Step 103: and the user equipment sends uplink control information UCI carrying the multiplexing information to base station equipment through a physical uplink control information PUCCH.
In the embodiment of the application, the user equipment processes the HARQ ACK/NACK and the SR, determines the corresponding PUCCH resource at the same time, and sends the multiplexing information of the HARQ ACK/NACK and the SR to the base station equipment through the determined PUCCH resource in the PUCCH.
The PUCCH Resource herein may refer to a location of a Physical Resource Block (PRB). In the embodiment of the present application, the position of the PRB may be determined explicitly or implicitly.
It should be noted that, in the embodiment of the present application, the position of the PRB may be determined in a configuration manner.
For example: multiplexing information, cyclic shift numbers, and positions of physical resource blocks PRB for transmitting the cyclic shift numbers/multiplexing information are configured in advance.
Specifically, the mapping relationship between the cyclic shift number and the multiplexing information of the harq ack/NACK and SR is shown in table 1 below:
TABLE 1
Circulation ofNumber of shifts Multiplexing information of HARQ ACK/NACK and SR
CS1 Bundled ACK + positive SR
CS2 Bundled NACK + positive SR
CS3 Bundled ACK + negative SR
CS4 Bundled NACK + negative SR
Then the ue may determine the cyclic shift number corresponding to the obtained multiplexing information according to the mapping relationship between the configured multiplexing information and the cyclic shift number;
and the user equipment carries the multiplexing information carried on the position of the PRB and/or the determined cyclic shift number in UCI through a PUCCH according to the position of the configured physical resource block PRB for transmitting the cyclic shift number and transmits the multiplexing information and/or the determined cyclic shift number to base station equipment.
If the HARQ ACK/NACK and the SR determined by the user equipment are HARQ ACK and positive SR, bundling the HARQ ACK, and combining the bundled HARQ ACK and the positive SR at the same time, wherein the determined multiplexing information is bundled ACK + positive SR; then the cyclic shift number corresponding to the user equipment is CS1 according to the mapping shown in table 1 above.
If the HARQ ACK/NACK and the SR determined by the user equipment are HARQ NACK and negative SR, bundling the HARQ NACK, and combining the bundled HARQ NACK and the negative SR at the same time, wherein the determined multiplexing information is bundled NACK + negative SR; then the cyclic shift number corresponding to the user equipment is CS4 according to the mapping shown in table 1 above.
Assuming that the number of physical resource block PRB locations configured for transmitting the cyclic shift number is one, fig. 2 is a schematic diagram of the cyclic shift number and the PRB locations provided in the embodiment of the present application.
As can be seen from fig. 2, after a PRB position is configured, after the user equipment determines the cyclic shift number, multiplexing information corresponding to the cyclic shift number is carried on the configured PRB position and sent to the base station equipment through a PUCCH, so that the base station equipment can quickly obtain uplink control information carrying the multiplexing information sent by the user equipment.
It should be noted that the "configuring one PRB location" herein may be determined according to a location of a downlink control channel carrying the downlink data to be transmitted, or may be in another manner, and is not specifically limited herein.
Preferably, a plurality of PRB locations may be configured, that is, corresponding first PRB locations are configured for the SRs respectively; and configuring a corresponding second PRB position for the HARQ ACK/NACK.
In the embodiment of the present application, the following manner may be adopted
Determining the corresponding relation among multiplexing information, cyclic shift number and physical resource block PRB position:
determining a first PRB position corresponding to the SR and a second PRB position corresponding to the HARQ ACK/NACK;
if the multiplexing information is bundled ACK + positive SR, determining a corresponding relation among the bundled ACK + positive SR, the first cyclic shift number and the first PRB position;
if the multiplexing information is bundled NACK + positive SR, determining the corresponding relation among the bundled NACK + positive SR, the second cyclic shift number and the first PRB position;
if the multiplexing information is bundled ACK + negative SR, determining the corresponding relation among the bundled ACK + negative SR, the third cyclic shift number and the second PRB position;
and if the multiplexing information is bundled NACK + negative SR, determining the corresponding relation among bundled ACK + negative SR, the fourth cyclic shift number and the second PRB position.
It should be noted that, in the "first PRB position" and the "second PRB position," the first PRB position may be determined according to a position of a downlink control channel carrying the downlink data to be transmitted, and the second PRB position may be obtained through higher layer signaling configuration.
Specifically, the user equipment determines cyclic shift data and physical resource block PRB positions corresponding to the obtained multiplexing information according to a mapping relationship among configured multiplexing information, the cyclic shift data and physical resource block PRB positions;
and the user equipment carries the multiplexing information carried on the position of the PRB and/or the determined cyclic shift number in UCI through a PUCCH and sends the UCI to base station equipment.
Fig. 3 is a schematic diagram of cyclic shift numbers and PRB locations according to an embodiment of the present disclosure.
As can be seen from fig. 3, two PRB locations are configured, where PRBX corresponds to SR; PRBY corresponds to HARQ ACK/NACK. In the above manner, it can be obtained: the multiplexing information corresponding to the PRBX is bundled ACK + positive SR and bundled NACK + positive SR, which indicates that HARQ ACK/NACK is sent on SR resources to realize true multiplexing of the HARQ ACK/NACK and the SR; multiplexing information corresponding to the PRBY is bundled ACK + negative SR and bundled NACK + negative SR, which indicates that the SR is not multiplexed in the HARQ ACK/NACK resources.
The method can be applied to the scene with high channel delay, and can effectively improve the rate of detecting the uplink control information by the base station equipment.
Preferably, the user equipment determines a PRB position of a downlink control channel carrying the downlink data to be transmitted;
the user equipment obtains the PRB position of the uplink control channel corresponding to the PRB position of the downlink control channel according to the mapping relation between the configured PRB position of the downlink control channel and the PRB position of the uplink control channel;
and the user equipment sends uplink control information UCI carrying the multiplexing information to base station equipment through the acquired PRB position in the PUCCH.
That is to say, the user equipment carries the multiplexing information in the PRB position, and the base station equipment can accurately acquire the multiplexing information carried in the UCI by decoding when receiving the UCI sent by the user equipment, thereby determining whether the user equipment confirms downlink data and whether the user equipment needs to schedule information such as resources.
Preferably, the sending, by the ue, the uplink control information UCI carrying the multiplexing information to the base station equipment through the physical uplink control information PUCCH includes:
the user equipment determines a first PRB position and a configured second PRB position, wherein the first PRB position is determined according to the position of a downlink control channel for bearing and sending the downlink data;
the user equipment determines a cyclic shift number and a PRB position corresponding to the obtained multiplexing information according to the configured multiplexing information, the cyclic shift number and the corresponding relationship between the PRB positions of the physical resource blocks, wherein the PRB position is one of the first PRB position and the second PRB position;
and the user equipment carries the multiplexing information carried on the position of the PRB and/or the determined cyclic shift number in UCI through a PUCCH and sends the UCI to base station equipment. .
It should be noted that, in the "first PRB position" and the "second PRB position," the first PRB position may be determined according to a position of a downlink control channel carrying the downlink data to be transmitted, and the second PRB position may be obtained through higher layer signaling configuration.
Specifically, the correspondence between the configured multiplexing information and different positions may be as follows:
if the multiplexing information contains a Positive SR, configuring a corresponding relation between the multiplexing information and the first PRB position information; if the multiplexing information contains a negative SR, configuring a corresponding relation between the multiplexing information and second PRB position information; or,
if the multiplexing information contains a Positive SR, configuring a corresponding relation between the multiplexing information and second PRB position information; and if the multiplexing information contains a negative SR, configuring the corresponding relation between the multiplexing information and the first PRB position information.
It should be noted that, in the embodiments of the present application, the contents of "mapping relationship between preconfigured multiplexing information and cyclic shift numbers and position of physical resource block PRB configured for transmitting cyclic shift numbers", "mapping relationship between different configured cyclic shift numbers and different physical resource block PRB positions", and the like, may also be notified to the user equipment by the base station equipment through signaling, and are not described herein again.
According to the technical scheme provided by the embodiment of the application, the user equipment performs binding processing on the HARQ ACK/NACK corresponding to the downlink data to obtain bound bundled ACK/NACK; combining the bundled ACK/NACK and Scheduling Request (SR) information to obtain multiplexing information of the bundled ACK/NACK and the SR; and transmitting the UCI carrying the multiplexing information to base station equipment through a PUCCH. When the user equipment sends the HARQ ACK/NACK, the HARQ ACK/NACK is bundled and combined with the SR to obtain bundled ACK/NACK and multiplexing information of the SR, and therefore the multiplexing information is carried in the uplink control information through the uplink control channel and sent to the base station equipment, resource overhead of the uplink control channel is effectively reduced, the purpose of improving the utilization rate of the uplink control resource is achieved, and meanwhile the system requirement of the 5G network is met.
