Solution Overview

Problem

In the HS-SCCH less operation of CPC in wireless communications systems, existing technologies waste system radio resources by requiring 4 bits to configure a second HS-PDSCH code, which is not always necessary, leading to inefficient radio resource control.

Innovation Solution

Configuring a first HS-PDSCH code using a variable 'HS-PDSCH Code Index' and optionally configuring a second HS-PDSCH code using a Boolean variable indicated by one bit, allowing simultaneous use of both codes only when needed, thereby reducing the number of bits required for transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a second HS-PDSCH code is configured using a 4-bit variable, then the system can support TB reception for each TB size listed in the Transport Block Size List, but the number of bits required for transmission increases, wasting system radio resources

Engineering Contradiction:
ImproveTB reception supportVSAvoidnumber of bits for transmission
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent makes the HS-PDSCH code configuration dynamic by introducing a Boolean variable that is activated only when a second HS-PDSCH code is actually needed. This allows the system to adapt the configuration to actual requirements rather than always allocating resources for a potential second code, thus reducing unnecessary bit transmission while maintaining TB reception capability when needed

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter representation from a fixed 4-bit variable to a dynamic Boolean variable (1 bit) combined with conditional logic. This parameter change allows the system to convey the same information more efficiently by only transmitting the second code index when necessary, thereby reducing the average number of bits required for transmission

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the network transmits the second HS-PDSCH code index for every TB size configuration, then complete TB reception support is ensured, but system radio resources are wasted due to unnecessary transmissions

Engineering Contradiction:
ImproveTB reception completenessVSAvoidsystem radio resource consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies partial action by transmitting the second HS-PDSCH code index only when actually needed, rather than always transmitting it for every TB size configuration. The Boolean variable acts as a gatekeeper, enabling the system to perform the complete configuration action only when necessary, thus avoiding excessive radio resource consumption while maintaining TB reception completeness

Inventive Principle:
Principle #16Partial or excessive action

AI summary

In order to enhancing system efficiency of radio resource control, the present invention provides a method for a user equipment in a wireless communications system for improving functions of continuous packet connectivity. The method includes configuring a first HS-PDSCH code of a user equipment according to a variable "HS-PDSCH Code Index" of an information element "HS-SCCH Less Information" before the user equipment activates an HS-SCCH less operation (302), and configuring a second HS-PDSCH code of the user equipment according to a Boolean variable of the information element "HS-SCCH Less Information", wherein the Boolean variable is indicated by one bit and the second HS-PDSCH code is an adjacent channel code of the first HS-PDSCH code (304).
