Multi-Frequency HSDPA Control Channel Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current HSDPA technology is limited to single-frequency operation, preventing user equipment (UE) from concurrently receiving data at multiple frequencies, which restricts network resource utilization and data transmission efficiency in multi-frequency environments.
Innovation Solution
The method involves allocating a control channel set and a list of frequencies to UE based on capability and network resources, transmitting control information through multiple downlink shared control channels, and receiving data on respective frequencies using a modified HS-SCCH structure with added frequency indicators, allowing UE to process data across multiple frequencies.

Engineering Contradiction Analysis
1Productivity
If HSDPA technology operates at single frequency, then system complexity is reduced and compatibility is maintained, but network resource utilization and data transmission efficiency are limited
Solution Approach 1:
The patent segments the control channel resources by introducing frequency-specific HS-SCCH channels. Each frequency point has its own HS-SCCH channel, allowing independent control of data transmission on each frequency. This segmentation enables multi-frequency operation while maintaining manageable system complexity through structured resource allocation.
Solution Approach 2:
The patent creates a universal control framework where the HS-SCCH structure can operate at multiple frequency points simultaneously. The control channel design is generalized to support both single-frequency and multi-frequency operations, making the system adaptable to different deployment scenarios without requiring separate control mechanisms.
2Adaptability or versatility
If multiple HS-SCCH channels are allocated for multi-frequency operation, then control capability is enhanced, but channel resource consumption increases
Solution Approach 1:
The patent implements dynamic allocation of HS-SCCH channels based on actual data transmission needs. The network can activate or deactivate specific frequency points and their associated control channels according to traffic conditions, channel quality, and UE capabilities. This dynamic approach enhances control capability while avoiding unnecessary channel resource consumption when multi-frequency operation is not required.
Data Source
AI summary
A technique for receiving multi-frequency data in a high speed downlink access service is disclosed. In this manner, one or more deficiencies of current HSDPA technology are mitigated, such as where user equipment (UE) can merely be scheduled by the network side at a single frequency. Among other things, a control channel set and a list of frequencies for user equipment (UE) are exchanged between a network side and UE accessing the network.
