HARMONIZATION OF MULTIPLE CONFIGURED GRANT UPLINK WITH OR WITHOUT RETRANSMISSION TIMER - A simplified explanation of the abstract
- This abstract for appeared for patent application number 18022967 Titled 'HARMONIZATION OF MULTIPLE CONFIGURED GRANT UPLINK WITH OR WITHOUT RETRANSMISSION TIMER'
Simplified Explanation
The abstract describes a method for improving the efficiency of retransmissions in wireless communication. It introduces two types of grants: dynamic grants (DG) and configured grants (CG). DGs use communication resources more efficiently, while CGs reduce overhead and latency. The base station configures the user equipment (UE) with a retransmission timer or without one using radio resource control signaling. The base station then transmits a set of CG configurations to the UE, which includes information about whether a retransmission timer is associated with the CG processes. The base station can receive communication from the UE based on these CG processes and the presence or absence of a retransmission timer. By combining CG and DG based retransmissions, the method reduces latency, overhead, and resource usage, especially when the UE has different channel conditions for multiple CG processes.
Original Abstract Submitted
Dynamic grants (DG) for retransmission by a user equipment (UE) use the communication resource more efficiently while configured grants (CG) for retransmission by the UE reduce overhead and latency. A base station (BS) uses radio resource control signaling to configure the UE with a retransmission timer or without a retransmission timer. The BS transmits to the UE a set of CG configurations configuring a set of configured grant uplink (CG-UL) processes. The set of CG configurations includes information indicating whether or not a cg-RetransmissionTimer is associated with the CG-UL processes. The BS is also configured to receive communication on UL from the UE. The communication from the UE is received based on the set of CG-UL processes and the indication whether or not a cg-RetransmissionTimer is associated with the CG-UL processes. A UE may have different channel conditions for a plurality of CG-UL processes of the UE and therefore using a combination of CG based retransmission and DG based retransmission will reduce latency and reduce overhead and use the resource more efficiently.
