Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and a terminal for transmitting a hybrid automatic repeat request response message.
Background
The fifth generation (5) in the future, compared with the conventional mobile communication systemthGeneration, 5G) mobile communication system, or New Radio (NR) system, needs to adapt to more diversified scenarios and service requirements. The main scenes of the 5G comprise mobile broadband enhancement eMBB, large-scale Internet of things mMTC and ultra-high-reliability ultra-low-delay communication uRLLC, and the scenes provide requirements on the system such as high reliability, low delay, large bandwidth and wide coverage. In order to meet different services with different requirements and different application scenarios, the subcarrier spacing of the NR system is no longer the same as the conventional fourth generation (4)thGeneration, 4G), or Long Term Evolution (LTE), systems employ a single 15kHz to be the same, the systems can support multiple subcarrier spacings, and different subcarrier spacings can be suitable for different scenarios. For example, for a high frequency band and a large bandwidth, a relatively large subcarrier interval may be configured, and in addition, the large subcarrier interval corresponds to a small symbol length in a time domain, which may meet the requirement of a low latency service.
When Uplink Control Information (UCI) in the NR system is transmitted on a Physical Uplink Shared Channel (PUSCH), when a Hybrid Automatic Repeat Request acknowledgement (HARQ-ACK) is less than 2bits, the UCI is transmitted in a puncturing manner, and other UCI (including a first part of Channel State Indication (CSI)) and a second part of CSI, namely, CSI-part1 and CSI-part2, are transmitted in a rate matching manner. But the manner of puncturing may interfere with the signal rate-matched at the puncture location. In addition, in order to obtain better demodulation performance, UCI should be transmitted at a position as close as possible to the DMRS, and according to the priority of UCI, HARQ-ACK is greater than CSI PART1 and greater than CSI PART2, and UCI with a greater priority is closer to the DMRS. The mapping mode adopted in NR is: HARQ-ACK is mapped first at a position close to DMRS, and then CSI-part1 is mapped on resources after Resource Elements (REs) to which HARQ may be mapped. The reason why HARQ uses a puncturing method is that the network device and the terminal may understand how many bits of HARQ are transmitted differently, which may cause the base station to understand the number of resources occupied by HARQ incorrectly, resulting in demodulation failure. Therefore, before the punching transmission is performed, resources reserved for punching need to be determined, a user can only punch in the reserved resources during punching, and meanwhile, information with higher priority is not mapped in the reserved resources so as to avoid influencing the information with higher priority. If the terminal transmits the HARQ-ACK message in a mode of punching PUSCH data, the data performance is affected, and because the HARQ-ACK message and the CSI message are both mapped to resources close to the DMRS for transmission, resource conflict may exist, so that the problem of resource conflict between the HARQ-ACK message and the CSI message is avoided, and the problem that the transmission of the CSI message is not affected by the HARQ-ACK message is to be urgently solved by an NR system is ensured.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein.

An embodiment of the present invention provides a transmission method for a hybrid automatic repeat request response message, which is applied to a terminal, and as shown in fig. 1, the method includes the following steps:
step 11: and determining reserved resources for transmitting the hybrid automatic repeat request-acknowledgement (HARQ-ACK) message in the uplink transmission channel.
The Uplink transport Channel includes a Physical Uplink Control Channel (PUCCH) and/or a PUSCH, or is referred to as UL-CCH and/or UL-SCH. The reserved resource includes at least one RE, and the reserved resource may be located on the same OFDM symbol as a transmission resource for transmitting other UCI information, as shown in fig. 2, which is a schematic diagram of the reserved resource for uplink information transmission determined by the terminal.
Step 12: at least a portion of the reserved resources are punctured and the HARQ-ACK message is transmitted over the punctured resources.
If the bit number for transmitting the HARQ-ACK message is equal to or less than 2bits, the transmission can be performed in a puncturing mode.
After determining the reserved resources for transmitting the HARQ-ACK message in step 11, the method further includes: the first part of the channel state indication information in the uplink control information UCI is transmitted through other resources in the uplink transmission channel except the reserved resources, that is, in order to reduce the influence on data and other UCI information, the terminal may reserve a part of resources (all or part of REs of one or more OFDM symbols) for HARQ-ACK transmission, where the reserved resources limit the transmission of CSI-part1 with higher priority, but do not limit the transmission of other uplink information, such as uplink data and CSI-part 2.
In addition, step 11 determines reserved resources for transmitting the HARQ-ACK message, but no HARQ-ACK message is actually required to be transmitted by the terminal, and the reserved transmission resources may be used for the second part of the channel state indication information in the uplink data and/or the uplink control information. Or, as shown in fig. 3, when the resources actually punctured for the HARQ-ACK message by the terminal do not use up all the reserved resources, that is, the terminal partially reserves the resources for puncturing the HARQ-ACK message, the method further includes: and transmitting the second part of the channel state indication information in the uplink data and/or the uplink control information by reserving resources which are not punched in the resources.
The following embodiment will further describe how to determine reserved resources for transmitting the HARQ-ACK message in conjunction with a specific application scenario and a drawing.
In a first way,
The step 11 comprises the following steps: receiving offset information sent by a network device through Radio Resource Control (RRC) signaling; determining the number of resources required to be reserved for transmitting the HARQ-ACK message according to the offset information; and determining reserved resources for transmitting the HARQ-ACK message in the uplink transmission channel according to the number of the resources.
Specifically, when the offset information is an offset set including at least one offset, the offset information includes at least one first offset. The step of determining the number of resources required to be reserved for transmitting the HARQ-ACK message according to the offset information comprises the following steps: and determining the corresponding resource quantity according to the first offset. The network device sends a set to the terminal through RRC signaling, wherein the set comprises at least one first offset, and the set is used for dynamically indicating a candidate set for calculating the number of REs occupied by UCI when the UCI is transmitted on a PUSCH. Each set may contain multiple offsets, such as a first Offset (beta-Offset-ACK-Index-1), and each set may further include: the values of beta-Offset-ACK-Index-2, beta-Offset-ACK-Index-3, beta-Offset-CSI-part-1-Index-1, beta-Offset-CSI-part-1-Index-2, beta-Offset-CSI-part-2-Index-1, and beta-Offset-CSI-part-2-Index-2. The Beta-Offset-ACK-Index-1 may have one or more values. Specifically, after the RRC connection is established, the network device may configure a terminal with a first offset (e.g., a value of beta _ offset _ ACK _ index _ 1) for transmitting UCI information.
In a first scenario, when the number of the first offsets is one, the number of resources determined according to the first offsets is determined as the number of resources required to be reserved for transmitting the HARQ-ACK message.
The network device sends a first offset amount to the terminal through RRC signaling, the set including a first offset. The terminal determines the value of the first offset as an input parameter for calculating the number of resources required to be reserved for transmitting the HARQ-ACK message, and calculates the number of resources required to be reserved for transmitting the HARQ-ACK message by combining other input parameters.
And in a second scenario, when the number of the first offsets is at least two, determining the maximum value of the resource number determined according to the first offsets as the number of the resources required to be reserved for transmitting the HARQ-ACK message.
The network equipment sends a set to the terminal through RRC signaling, the set comprises at least two first offsets, one of a plurality of resource quantities calculated by the terminal according to the first offsets is selected according to a preset rule in the values and is determined as the reserved resource in the HARQ-ACK punching operation, for example, the maximum value in all the resource quantities calculated according to the first offsets as input parameters is determined as the quantity of the reserved resource needed for transmitting the HARQ-ACK message.
And a third scenario, when the number of the first offsets is at least two, determining the maximum value of the resource number calculated according to the first offsets and the smaller value of the preset resource number as the resource number which is reserved for transmitting the HARQ-ACK message.
The network device sends a set to the terminal through RRC signaling, the set comprises at least two first offsets, the terminal selects one of a plurality of resource quantities calculated by the first offsets according to a preset rule among the values to determine the resource reserved during the HARQ-ACK punching operation, for example, the maximum value of all the resource quantities calculated by using the first offsets as input parameters is used as a reference factor for determining the quantity of the resource reserved for transmitting the HARQ-ACK message, and in addition, the network device is configured with one preset resource quantity, or a protocol defines one preset resource quantity as another reference factor. In order to avoid reserving excessive resources, the terminal may determine the largest value of the number of resources calculated according to the first offset and the smaller value of the preset number of resources as the number of resources that need to be reserved for transmitting the HARQ-ACK message.
Further, when the offset information is used to determine an offset value in the set of offsets for the number of reserved resources required for transmitting the HARQ-ACK message. The step of determining the number of resources required to be reserved for transmitting the HARQ-ACK message according to the offset information comprises the following steps: and determining the number of reserved resources required for transmitting the HARQ-ACK message according to the offset value. Here, the network device configures the terminal with a determined offset value, which may be semi-statically or dynamically configured by the network device. Specifically, the network device may send an offset set including at least one offset to the terminal in advance, and when the network device determines that an ARQ-ACK message needs to be transmitted, dynamically send an offset index value to the terminal to indicate which offset value in the offset set is specifically selected by the terminal, so that the terminal may calculate the number of resources required to be reserved for transmitting the HARQ-ACK message according to the specific offset value as an input parameter for calculating the number of resources required to be reserved for transmitting the HARQ-ACK message, thereby calculating the number of resources required to be reserved for transmitting the HARQ-ACK message. In addition, the network device can also directly send the index value of a certain offset value to the terminal, so that the terminal can be used as an input parameter for calculating the number of the resources required to be reserved for transmitting the HARQ-ACK message according to the specific offset value, and the number of the resources required to be reserved for transmitting the HARQ-ACK message can be calculated.
The second way,
The third method,
That is, the terminal estimates a fixed value (S _ reserved) for the number of resources reserved for HARQ-ACK message puncturing according to a preset manner. Specifically, the fixed value (S _ reserved) varies with the length of the time slot used for the user to transmit data, i.e., in relation to the number of time slots of the uplink transmission channel. Further, the fixed value (S _ reserved) also varies with the frequency bandwidth used for the user to transmit data, i.e., in relation to the frequency bandwidth of the uplink transmission channel. A special case is that the fixed value is equal to the number of occupied REs within one OFDM symbol. Taking PUSCH as an example, since the time domain symbol number of PUSCH in NR may vary, such as: 2. 4, 7, and 14, etc., and at least one symbol is a DMRS symbol position. Therefore, when the PUSCH is a 2 symbol, one column of symbols occupied by the DMRS is removed, and only one symbol is left to transmit UCI and uplink data. In order to ensure the balance of the transmission resources of different uplink information, a fixed value (S _ reserved) may be estimated according to a preset manner (implicit) for the number of resources reserved for HARQ-ACK mapping, for example, the number of resources reserved for HARQ-ACK mapping may be determined according to the length of the time slot for transmitting data by the user and/or the frequency bandwidth for transmitting data by the user and/or the MCS manner of the HARQ-ACK message channel.
The fixed value (S _ reserved) varies depending on the Modulation and Coding Scheme (MCS) of the transmission channel used for the user to transmit the HARQ-ACK message, that is, it is related to the MCS of the uplink transmission channel used to transmit the HARQ-ACK message. Taking the PUSCH as an example, since the channel for transmitting the HARQ-ACK message may adopt different MCSs, such as pi/2BPSK or QPSK, and the same beta-Offset, the number of resources for transmitting the HARQ-ACK calculated by different MCSs is different. The MCS should be considered when calculating the reserved resources. For calculating reserved resources using QPSK and pi/2BPSK, the number of REs reserved may have an offset value, RE _ beta _ offset _ QPSK — RE _ beta _ offset _ QPSK alpha, alpha may be configured or specified in the protocol.
In the transmission method of the hybrid automatic repeat request response message, the terminal determines the reserved resources for transmitting the HARQ-ACK message, at least part of the reserved resources are selected to be punched to transmit the HARQ-ACK message, and the CSI-part1 is transmitted through other resources except the reserved resources, so that the problem of resource conflict between the HARQ-ACK message and the CSI information is avoided, and the transmission of the HARQ-ACK message is ensured not to influence the transmission of the CSI-part1 in the CSI information.
