Engineering Contradiction Analysis
1Loss of energy
If the base station indicates values for communication parameters to apply to subsequent communication, then power saving is achieved, but communication, computing, network, or power resources of the UE or base station are consumed
Solution Approach 1:
The patent segments the communication parameters into two categories: first communication parameters (PDSCH configuration, DCI configuration, DMRS configuration) and second communication parameters (TBS configuration, BLER configuration, layer configuration). This segmentation allows the base station to indicate different parameter sets based on power saving mode, reducing the need to transmit all parameters explicitly and thereby conserving communication resources while achieving power saving objectives.
Solution Approach 2:
The patent applies preliminary action by having the UE apply communication parameters based on previously indicated power saving mode without requiring explicit indication of each parameter value. The UE autonomously determines which parameter set to use based on the power saving mode indication, eliminating the need for continuous explicit parameter signaling and reducing resource consumption.
2Adaptability or versatility
If dynamic signaling is used to carry values for communication parameters, then flexibility is achieved, but information fields are limited
Solution Approach 1:
The patent segments communication parameters into first and second categories with different configuration requirements. First communication parameters are associated with power saving mode indications, while second communication parameters have separate configurations. This segmentation allows flexible parameter selection without requiring all parameters to be carried in limited information fields, as only relevant parameters need to be explicitly signaled.
Solution Approach 2:
The UE performs self-service by autonomously selecting and applying the appropriate communication parameter set based on the power saving mode indication without requiring explicit indication of each parameter. This self-determination mechanism provides flexibility in parameter configuration while avoiding the need to transmit all parameter values through limited information fields.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a power saving mode of a base station. The UE may communicate with the base station using one or more communication parameters that are based at least in part on the power saving mode, the one or more communication parameters comprising one or more of: a physical downlink shared channel configuration, a downlink control information configuration, a demodulation reference signal configuration, a transport block size configuration, a block error rate configuration, or a layer configuration. Numerous other aspects are provided.
