Dynamic Transport Block Size Selection for Random Access Signaling

The patent implements dynamic selection of transport block size and repetition number based on actual channel conditions and device requirements. The system allows devices to adaptively choose from multiple configured TBS values and repetition numbers, transitioning from fixed to dynamic parameters. This enables devices in good coverage conditions to use smaller TBS and fewer repetitions, reducing power consumption while maintaining reliability for devices in poor coverage.

The patent introduces multiple configured transport block size values and repetition number combinations that can be selected based on channel quality indicators. The network configures a set of TBS values and repetition numbers, and devices select appropriate parameters based on measured channel conditions. This parameter adaptation resolves the contradiction by matching resource allocation to actual needs, reducing unnecessary power consumption while preserving coverage enhancement where required.

The patent enables dynamic parameter selection where devices choose transport block size and repetition number based on actual channel conditions rather than using fixed values. This dynamic adaptation reduces signaling overhead because the system only needs to configure a set of possible values, not continuously adjust parameters for each transmission. Devices autonomously select from pre-configured options, reducing the need for extensive signaling exchanges.

The patent empowers devices to autonomously select appropriate transport block size and repetition number from configured sets based on their own channel condition assessments. This self-service mechanism reduces signaling overhead by eliminating the need for network-controlled parameter adjustment for each random access attempt. The device independently determines optimal parameters within the configured range, reducing uplink and downlink signaling requirements.

The patent applies local quality by allowing different transport block sizes to be selected based on device-specific data requirements and channel conditions. Instead of uniformly allocating large TBS to all devices, the system enables each device to choose the appropriate TBS from configured values that matches its actual data transmission needs. This localized adaptation eliminates resource waste for IoT devices with small data packets while maintaining high capacity for devices requiring larger transmissions.

The patent introduces multiple configured transport block size values that allow the system to adapt TBS to actual data requirements. The network configures a set of TBS values, and devices select from this set based on their data buffer status and channel conditions. This parameter flexibility resolves the contradiction by enabling small TBS for IoT devices with minimal data, eliminating resource waste, while preserving the capability to use large TBS when high data transmission capacity is actually needed.

The patent implements dynamic repetition number selection where devices adaptively choose the number of repetitions based on channel conditions and device type. The system configures multiple repetition number options, and devices select appropriate repetition counts based on their coverage requirements. IoT devices in good coverage can select zero or one repetition, eliminating unnecessary delays, while devices in poor coverage automatically select higher repetition numbers to ensure reliable delivery, thus resolving the latency-reliability trade-off.

The patent introduces configurable repetition number parameters that allow the system to adapt transmission redundancy to actual channel conditions. The network configures a set of repetition numbers, and devices select from this set based on measured channel quality and device category. This parameter adaptation enables the system to minimize repetitions (reducing latency) for devices in good coverage while maintaining high reliability through increased repetitions only where necessary, resolving the contradiction between coverage reliability and transmission latency.
