Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LTE system lacks a method for transmitting uplink control information with greater than 11 bits on the Physical Uplink Shared Channel (PUSCH) and cannot determine the number of resources required in each layer for such transmission.
Innovation Solution
A method and terminal for transmitting uplink control information, which involves coding the information into two parts, determining the number of coded symbols required for each layer, and forming a coded modulation sequence using linear block codes or tail-biting convolutional codes, allowing for efficient transmission on the PUSCH.

Engineering Contradiction Analysis
1Quantity of substance
If the LTE system uses existing coding methods for uplink control information, then transmission is supported for 11 bits or less, but transmission of uplink control information with greater than 11 bits is not supported
Solution Approach 1:
The patent divides uplink control information with greater than 11 bits into two separate parts: the first part contains the most significant bits and is coded using a (32, O) block code, while the second part contains the remaining bits and is coded using a (64, O) block code. This segmentation allows the system to handle larger bit quantities by applying different coding schemes to different portions of the data, thereby enabling transmission of uplink control information exceeding 11 bits on the PUSCH.
2Productivity
If the LTE system transmits uplink control information on PUSCH, then data and control information can be multiplexed, but the number of resources required in each layer cannot be determined for information greater than 11 bits
Solution Approach 1:
The patent introduces specific parameters for resource determination including beta_offset_PUSCH for control information weighting, alpha for resource allocation proportion, and Qm for modulation order. These parameters enable the system to calculate the number of coded symbols required in each layer based on the multiplexing ratio between control information and data, allowing resource determination for uplink control information with greater than 11 bits while maintaining multiplexing efficiency.
3Ease of manufacture
If existing coding schemes are used, then simple coding is applied, but the coding rate and resource allocation cannot be optimized for larger bit quantities
Solution Approach 1:
The patent implements dynamic coding rate adjustment by selecting between different block codes ((32, O) or (64, O)) based on the bit quantity of the first part of the control information. The coding rate is dynamically determined by the ratio of information bits to coded symbols, and the number of coded symbols is adjusted based on beta_offset_PUSCH and the total number of available symbols. This dynamic approach maintains coding simplicity through standardized block codes while achieving precise coding rate optimization for larger bit quantities.

AI summary
The disclosure discloses a method and terminal for transmitting uplink control information. The method includes: coding the uplink control information required to be transmitted and data information corresponding to one or two transport blocks respectively, obtaining an encoded sequence according to a target length, and forming a corresponding coded modulation sequence from the encoded sequence according to a modulation mode (401); interleaving the obtained coded modulation sequence, and transmitting the interleaved coded modulation sequence on a layer corresponding to a Physical Uplink Shared Channel (PUSCH) (402). By adopting the method and terminal according to the disclosure the transmission of uplink control information with greater bits on the PUSCH is realized. The disclosure also provides a method for determining a number of code symbols required in each layer when transmitting uplink control information on the PUSCH, thus the purpose of determining a number of code symbols required in each layer when transmitting uplink control information on the PUSCH is realized.
