Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks, particularly those using 5G New Radio (NR) communications, ensuring satisfactory radio-frequency (RF) control timing and receiver performance for devices with varying capabilities within the same cell is challenging due to differences in transition times, transient periods, and processing delays, which affects the overall wireless communications.
Innovation Solution
A method where the wireless base station schedules communications with each device based on its specific capabilities by allocating gap symbols and delay times, allowing for efficient RF control timing and receiver performance, even at high frequencies above 10 GHz, using techniques like open and closed loop transmit power control.

Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless base station serves multiple devices with different communications capabilities in the same cell, then the network can support diverse device types and maintain high connectivity, but it becomes difficult to provide satisfactory wireless communications for all devices due to varying transition times, transient periods, and processing delays
Solution Approach 1:
The patent applies local quality by configuring device-specific parameters (transitionTime, transientPeriod, processingDelay) for each user equipment based on its individual capabilities. The base station tailors the communication schedule to each device's specific RF control timing requirements, allowing diverse device types to operate reliably within the same cell by accommodating their unique temporal characteristics.
Solution Approach 2:
The patent implements dynamics by making the communication schedule adaptive to each device's capabilities. The base station dynamically adjusts timing parameters and gap symbol allocations based on the specific transition times, transient periods, and processing delays of each user equipment, enabling the system to flexibly accommodate varying device performance characteristics.
2Reliability
If the base station schedules communications based on each device's specific capabilities, then satisfactory RF control timing and receiver performance can be achieved for all devices, but the scheduling complexity and computational requirements increase
Solution Approach 1:
The patent applies preliminary action by having each user equipment report its capability parameters (transitionTime, transientPeriod, processingDelay) to the base station in advance. This pre-configured information allows the base station to pre-calculate and optimize communication schedules that accommodate each device's specific timing requirements, reducing real-time scheduling complexity while maintaining reliable RF control timing.
3Reliability
If gap symbols are inserted between uplink symbols to accommodate transient periods, then receiver performance and RF control timing are improved, but the communication latency and time efficiency decrease
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the number and duration of gap symbols based on each device's specific transient period requirements. Rather than using fixed gap allocations, the system modifies the temporal parameters of the communication schedule to match each user equipment's RF control timing characteristics, achieving reliable receiver performance while minimizing unnecessary time losses.

AI summary
An electronic device may communicate with a wireless base station using a 5G New Radio communications protocol. The base station may balance control timing and receiver performance for the devices in its cell by scheduling communications based on the communications capabilities of each device. This may ensure that the base station is able to provide communications with satisfactory control timing and receiver performance even if multiple different types of device are within its cell. In addition, the device may perform open loop transmit power control operations and then closed loop power control operations. To minimize complexity of the device, the device may only transmit at a maximum output power level during the open loop operations. If desired, the device may only transmit at the maximum output power level when the device is unable to decode a downlink reference signal transmitted by the base station within a predetermined number of symbols.
