Communication Device Handling Serving Cell Special Symbols
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication devices struggle to handle communications with serving cells due to the inability to perform multiple direction switches within a time period, leading to failures in operations with network devices.
Innovation Solution
The method involves receiving configurations from the network indicating sets of downlink, flexible, and uplink symbols, as well as special symbols comprising DL and UL sub-bands in different frequency regions. The communication device determines whether to perform operations that overlap with special symbols, considering power information and priority indexes to avoid multiple direction switches.

Engineering Contradiction Analysis
1Productivity
If the communication device performs multiple direction switches in a time period to satisfy increasing demand for signals, then the communication capacity is improved, but the device cannot perform more than one direction switch in the time period, leading to communication failure
Solution Approach 1:
The time period is segmented into different types of symbols (downlink symbols, uplink symbols, and flexible symbols) with different transmission directions. The flexible symbols are further segmented into first flexible symbols and second flexible symbols based on their directional characteristics. This segmentation allows the device to handle multiple direction switches by processing operations in different symbol types separately, avoiding the limitation of performing only one switch per time period.
Solution Approach 2:
The transmission direction configuration is made dynamic through flexible symbols that can be configured as downlink or uplink based on communication needs. The network can dynamically adjust the direction of flexible symbols to accommodate varying communication demands, allowing the device to adapt its transmission direction multiple times within a time period without being constrained by fixed directional switches.
2Adaptability or versatility
If the network configures operations with different transmission directions in a time period to satisfy signal demand, then the communication flexibility is improved, but the device fails to perform operations when multiple direction switches are required
Solution Approach 1:
Operations are segmented by transmission direction into downlink operations (receiving operations from network) and uplink operations (transmitting operations to network). The flexible symbols are segmented into first flexible symbols (configurable as downlink) and second flexible symbols (configurable as uplink). This segmentation allows the device to execute operations for different directions independently, improving ease of operation while maintaining communication flexibility.
Solution Approach 2:
The transmission direction parameter is made changeable through flexible symbols that can be configured with different directions (downlink or uplink) based on communication needs. This parameter change capability allows the network to adjust the transmission direction dynamically, enabling the device to perform operations with different transmission directions without failing to execute them.
3Productivity
If the communication device handles operations overlapping with special symbols, then the communication efficiency is improved, but the device must determine whether to perform operations based on power information and priority indexes
Solution Approach 1:
The network performs preliminary configuration by providing first configuration information (indicating downlink, flexible, and uplink symbol sets) and second configuration information (indicating special symbols with DL and UL sub-bands) before the device needs to execute operations. This preliminary action includes providing priority information and power information in advance, allowing the device to pre-determine how to handle overlapping operations without increasing complexity during actual operation execution.
Solution Approach 2:
The network provides feedback through configuration information that includes priority indexes and power information for different symbol types. This feedback mechanism enables the device to make informed decisions about whether to perform operations in special symbols based on pre-provided criteria, improving communication efficiency while keeping the determination process simple through structured feedback rather than complex real-time analysis.
