METHOD AND APPARATUS FOR CONFIGURING AN ASSISTANCE INFORMATION BIT FOR LOCAL CACHE BIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 17990269 titled 'METHOD AND APPARATUS FOR CONFIGURING AN ASSISTANCE INFORMATION BIT FOR LOCAL CACHE BIT
Simplified Explanation
The present disclosure describes a method and apparatus for transmitting and receiving data in a wireless communication system. The method involves configuring an assistance information bit for local cache (AILC) bit in a terminal that is connected to both a master base station and a secondary base station.
- The terminal receives a radio resource control (RRC) reconfiguration message from the master base station, which includes information about the configuration of the AILC bit (ailc-BitConfig).
- Based on various factors such as the terminating base station of a data radio bearer (DRB), whether the DRB includes a service data unit (SDU) to be transmitted to a local cache, whether the DRB is configured with evolved universal terrestrial radio access (E-UTRA) PDCP or New Radio (NR) PDCP, or the PDCP sequence number (SN) of the PDCP data PDU, the terminal configures the AILC bit of a packet data convergence protocol (PDCP) data packet data unit (PDU).
- The terminal then transmits the PDCP data PDU, with the AILC bit configured, to the terminating base station.
Potential applications of this technology:
- This technology can be applied in wireless communication systems to improve the efficiency of data transmission and reception.
- It can be used in scenarios where a terminal is connected to multiple base stations and needs to configure the AILC bit based on various factors.
Problems solved by this technology:
- The method and apparatus described in this patent application solve the problem of efficiently configuring the AILC bit in a terminal that is dual-connected to multiple base stations.
- It addresses the challenge of determining the configuration of the AILC bit based on factors such as the terminating base station, presence of SDU for local cache, PDCP type, and PDCP sequence number.
Benefits of this technology:
- The method and apparatus provide an efficient way to configure the AILC bit, which can improve the overall performance of data transmission and reception in a wireless communication system.
- By considering various factors, the technology ensures that the AILC bit is configured appropriately for each PDCP data PDU, optimizing the utilization of local cache and improving the efficiency of data delivery.
Original Abstract Submitted
The present disclosure relates to a method and apparatus for transmitting and receiving data in a wireless communication system. A method, performed by a terminal dual-connected to a master base station and a secondary base station in a wireless communication system, of configuring an assistance information bit for local cache (AILC) bit includes receiving, from the master base station, a radio resource control (RRC) reconfiguration message including AILC bit configuration information (ailc-BitConfig), configuring an AILC bit of a packet data convergence protocol (PDCP) data packet data unit (PDU) based on at least one of a terminating base station of a data radio bearer (DRB) through which the PDCP data PDU is transmitted, whether the PDCP data PDU includes a service data unit (SDU) to be transmitted to a local cache, whether the DRB is configured with evolved universal terrestrial radio access (E-UTRA) PDCP or New Radio (NR) PDCP, or a PDCP sequence number (SN) of the PDCP data PDU, and transmitting, to the terminating base station, the PDCP data PDU in which the AILC bit is configured.
