Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to an uplink control channel transmission method, a terminal device, and a network device. Background Art

[0002] In the 5G New Radio (NR) communication system, the transmission resources of the uplink control channel (Physical Uplink Control Channel, PUCCH) can be flexibly configured within a certain range. At the same time, the uplink control information (Uplink Control Information, UCI) that needs to be transmitted at a certain moment also changes dynamically. However, it is difficult to ensure that the transmission code rate of PUCCH meets the demodulation requirements when transmitting dynamically changing UCI on PUCCH resources with limited flexibility. For example, in an extreme case, a smaller PUCCH carries multiple bits of UCI, resulting in a UCI code rate greater than 1. In this case, the UCI will not be correctly demodulated by the network device (e.g., base station).

[0003] Therefore, how to reliably transmit UCI in 5G NR communication systems is an urgent problem to be solved. Summary of the invention

Figure 1 The terminal device shown in FIG. 200 may be a network device such as Figure 1 The network device shown in FIG. 2 , the method 200 includes the following contents.

[0080] 210. The terminal device determines a maximum code rate for transmitting an uplink control channel from the maximum code rate of at least one uplink control channel.

[0083] For example, the maximum code rate of the transmitted uplink control channel is determined based on at least one of the uplink control information type, the service corresponding to the uplink control information, the format of the uplink control channel (PUCCH Format), the resource configuration of the uplink control channel (PUCCHresource configuration), the scrambling method of the data corresponding to the uplink control information, and the downlink control channel configuration corresponding to the data corresponding to the uplink control information.

[0084] Optionally, the uplink control information type may be at least one of a hybrid automatic repeat request (Hybrid Auto Repeat Request, HARQ) feedback information confirmation character (ACKnowledge Character, ACK) / non-acknowledgement character (Non-ACKnowledge Character, NACK), channel state information (Channel State Information, CSI), and a service request (Service Request, SR).

[0085] Optionally, the service corresponding to the uplink control information may be at least one of Ultra-Reliable and Low-Latency Communications (URLLC), Enhanced mobile broadband (eMBB), and Massive Machine Type of Communication (mMTC).

[0086] Optionally, the priority order of UCI of the same service type may be SR / ACK / NACK>CSI.

[0087] It should be understood that SR, ACK, and NACK have the same priority level.

[0088] Optionally, the CSI may include a rank indication (RI), a precoding matrix indication (PMI) and a channel quality indication (Channel Quality Indicator, CQI).

[0089] Optionally, the CSI may be one or more of RI, CQI, and PMI.

[0090] Optionally, CSI can be divided into aperiodic CSI (A-CSI), semi-persistent CSI (S-CSI) and periodic CSI (P-CSI).

[0091] Optionally, CSI may include wideband information and narrowband information.

[0092] Optionally, priorities can be distinguished within CSI using the following three principles:

[0093] Principle 1: RI>PMI>CQI;

[0094] Principle 2: Broadband information > narrowband information;

[0095] Principle 3: Non-cyclical is superior to cyclical.

[0096] Optionally, the priority sorting of the same UCI information for multiple service types may be URLLC>eMBB>mMTC.

[0097] Optionally, the priorities of various UCI information of various service types may be determined according to the following principles.

[0098] Principle 1: Business Priorities First

[0099] Principle 1.1 Priority sorting refers first to the service type and uplink control information type, among which periodic uplink control information has the lowest priority.

[0100] The details are as follows:

[0101] URLLC SR / ACK / NACK>URLLC A-CSI>eMBB SR / ACK / NACK>eMBB A-CSI>URLLC S-CSI / P-CSI>eMBB S-CSI / P-CSI

[0102] Principle 1.2 Prioritization, first refer to business type.

[0103] The details are as follows:

[0104] URLLC SR / ACK / NACK>URLLC A-CSI>URLLC S-CSI / P-CSI>eMBB SR / ACK / NACK>eMBBA-CSI>eMBB S-CSI / P-CSI

[0105] Optionally, the priority information may be configured by a network device (eg, a base station).

[0107] It should be understood that the downlink control channel configuration is the downlink control channel configuration corresponding to the data corresponding to the uplink control information. For example, the terminal device feeds back the reception status of data B through the uplink control information. At this time, the downlink control channel configuration can be the configuration information of the downlink control channel carrying the downlink control information C indicating the data B.

[0108] Optionally, the scrambling information of the data may be a scrambling code sequence initialization parameter.

[0109] Optionally, the at least one maximum bit rate may be dynamically configured by the network device, for example, the network device sends configuration information to the terminal device, thereby configuring the at least one maximum bit rate.

[0110] Optionally, the network device may configure one or more maximum code rates for a downlink control channel.

[0111] For example, two maximum code rates are configured for a downlink control channel, corresponding to ACK / NACK and CSI feedback respectively.

[0112] Two maximum code rates are configured for a downlink control channel, corresponding to URLLC services and eMBB services respectively.

[0113] Two maximum code rates are configured for a downlink control channel, corresponding to data scrambling mode 1 and data scrambling mode 2 respectively.

[0114] Three maximum code rates are configured for a downlink control channel, corresponding to PUCCH format 2, PUCCH format 3, and PUCCH format 4 respectively.

[0115] Three maximum code rates are configured for a downlink control channel, corresponding to PUCCH resource1 and PUCCH resource2 respectively.

[0116] Optionally, the at least one maximum code rate may be configured by the network device based on the PUCCH format, for example, the network device configures the maximum code rates for PUCCH formats 2, 3, and 4. Optionally, different PUCCH formats may be configured with the same maximum code rate or different maximum code rates.

[0117] Optionally, the pre-configuration configures the at least one maximum code rate based on the PUCCH format, for example, one or more maximum code rates are respectively configured for PUCCH formats 2, 3, and 4. Optionally, different PUCCH formats may be configured with the same maximum code rate or different maximum code rates.

[0118] For example, two maximum code rates are configured for PUCCH format 2, corresponding to uplink control information types CSI and ACK / NACK in PUCCH format 2 respectively.

[0119] It should be understood that the CSI and ACK / NACK under PUCCH format 2 are merely examples and may also correspond to other downlink control channel configurations or service types and / or data scrambling methods, which are not limited in this application.

[0120] Optionally, multiple maximum code rates may respectively correspond to multiple uplink control information types and / or multiple service types and / or multiple downlink control channel configurations and / or multiple data scrambling modes.

[0121] Optionally, the at least one maximum code rate may be configured by the network device based on the PUCCH resource. For example, the network device preconfigures one or more maximum code rates for PUCCH resource 1 and PUCCH resource 2 respectively.

[0122] Optionally, the at least one maximum code rate is pre-configured based on the PUCCH resource, for example, one or more maximum code rates are pre-configured for PUCCH resource 1 and PUCCH resource 2 respectively.

[0123] For example, two maximum code rates are configured for PUCCH resource 1, corresponding to the downlink control information types CSI and ACK / NACK under PUCCH resource 1 respectively.

[0124] It should be understood that the CSI and ACK / NACK under PUCCH resource 1 are merely examples and may also correspond to other downlink control channel configurations or service types and / or data scrambling methods, which are not limited in this application.

[0125] Optionally, the at least one maximum bit rate may be directly preconfigured.

[0126] Optionally, if the network device configures the maximum code rate of the at least one uplink control channel, before the terminal device determines the maximum code rate for transmitting the uplink control channel from the maximum code rate transmitted by the at least one uplink control channel, the method 200 further includes:

[0127] The terminal device receives the at least one maximum bit rate configured by the network device.

[0128] Optionally, a maximum code rate may be configured for each type of uplink control information among the multiple types of uplink control information.

[0129] Optionally, the multiple uplink control information may be multiple types of uplink control information, may be uplink control information of multiple services, may be uplink control information corresponding to multiple downlink control channel configurations, or may be uplink control information corresponding to multiple scrambled data.

[0130] Optionally, the terminal device determines that the minimum value of the maximum code rates corresponding to multiple types of uplink control information is the maximum code rate for transmitting the uplink control channel.

[0131] 220. The terminal device determines the uplink control information carried in the uplink control channel according to the maximum code rate for transmitting the uplink control channel.

[0133] Optionally, the terminal device determines the uplink control information carried in the uplink control channel according to the maximum code rate for transmitting the uplink control channel and the priority of the uplink control information.

[0134] Therefore, in the uplink control channel transmission method of the embodiment of the present application, the terminal device can determine the uplink control information carried in the uplink control channel based on the maximum code rate of transmitting the uplink control channel, so that the terminal device can transmit the uplink control channel within a controllable code rate range, thereby ensuring the reliable transmission of the uplink control information carried in the uplink control channel, and at the same time, can improve the system transmission efficiency.

[0170] When N / M<=Rmax1, the terminal device encodes and transmits N-bit ACK / NACK using a code rate less than or equal to Rmax1.

[0171] When N / M>Rmax1, the terminal device adopts ACK / NACK compression method (for example, ACK / NACK compression package (bundling) or ACK / NACK compression multiplexing (multiplexing)) and / or ACK / NACK discarding method (for example, the discarding principle can be determined according to the time-frequency domain order of the service, the first to arrive has a higher priority, and the higher priority will not be discarded) for encoding and transmission.

[0195] When N / M>Rmax1, the terminal device adopts partial or full UCI compression (for example, partial UCI compression means that N1 bit for ACK / NACK is not compressed, and N2 bit for CSI is compressed) and / or UCI discarding (for example, the discarding principle can be determined according to the priority order of the service, the ACK / NACK priority is higher than the CSI priority, and the higher priority is not discarded) for encoding and transmission.

[0196] Method 2:

[0197] When N1*Rmax1+N2*Rmax1<=M, the terminal device encodes and transmits N bits of UCI using a code rate less than or equal to Rmax1.

[0206] Specifically, the terminal device needs to feedback N bits of UCI, and this N bit of UCI includes both ACK / NACK and CSI, and corresponds to URLLC and eMBB. The terminal device adopts partial or full UCI compression (for example, the principle of compression is that high priority is not compressed, low priority is compressed, and the priority order of the above services can be URLLC ACK / NACK>eMBBACK / NACK>URLLC CSI>eMBB CSI) and / or UCI discarding (for example, the discarding principle can be determined according to the priority order of the services, and the priority order of the above services can be URLLC ACK / NACK>eMBB ACK / NACK>URLLCCSI>eMBB CSI, and the high priority is not discarded) for encoding and transmission.
