Skipping SSB Transmissions for Established Beam Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in 5G networks, there is a challenge in efficiently managing synchronization signal blocks (SSBs) for beams with established connections, leading to unnecessary resource consumption and reduced throughput.
Innovation Solution
The method involves a user equipment (UE) and a network node establishing a connection using a beam, where the network node transmits an indication to refrain from transmitting SSB signaling during a portion of an SSB occasion associated with the beam, allowing for the use of other channels like tracking reference signals (TRS) and channel state information reference signals (CSI-RS) instead.

Engineering Contradiction Analysis
1Reliability
If SSB signaling is transmitted for all beams during SSB occasions, then synchronization and beam management are maintained, but unnecessary resource consumption occurs and throughput is reduced
Solution Approach 1:
The patent applies local quality by differentiating SSB transmission behavior based on connection status. For beams with established connections, SSB transmission is skipped or reduced, while for beams without connections, SSB transmission continues normally. This localized differentiation resolves the contradiction by maintaining synchronization only where necessary while freeing resources for throughput enhancement elsewhere.
Solution Approach 2:
The patent changes the transmission parameter of SSB signaling dynamically based on connection establishment status. When a connection is established on a beam, the SSB transmission parameter is modified (skipped or reduced). This parameter change resolves the contradiction by adapting resource allocation to actual network conditions, maintaining synchronization reliability while improving overall throughput.
2Reliability
If SSB signaling is continuously transmitted for beam management, then beam synchronization is maintained, but power and resources are consumed unnecessarily
Solution Approach 1:
The patent applies local quality by making SSB transmission decisions beam-specific rather than system-wide. For each beam, the network device determines whether to transmit SSB based on whether a connection is established on that specific beam. This resolves the contradiction by maintaining synchronization only on beams that require it while conserving power on beams where connections are already established.
Solution Approach 2:
The patent implements periodic SSB transmission only when necessary, rather than continuous transmission. By skipping SSB transmission in SSB occasions for beams with established connections, the system creates periodic transmission patterns that maintain synchronization while reducing power consumption. This periodic action resolves the contradiction between reliability and energy loss.

If SSB transmission is performed on all beams, then comprehensive coverage is ensured, but resource allocation efficiency decreases
Solution Approach 1:
The patent applies local quality by differentiating resource allocation based on beam-specific connection status. SSB transmission is maintained on beams requiring coverage while being skipped on beams with established connections. This localized approach resolves the contradiction by ensuring comprehensive coverage where needed while improving resource allocation efficiency overall.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish a connection with a network node using a beam. The UE may receive, based at least in part on establishing the connection using the beam, an indication that the network node will refrain from transmission of synchronization signal block (SSB) signaling during a portion of an SSB occasion associated with the beam. Numerous other aspects are described.
