Problems solved by technology

[0005] However, if the entire data is simply discarded when the radio bearer is released, this may result in an ineffective use of resources
This is because, when successfully received data is discarded due to release of the radio bearer, the data may then be retransmitted repeatedly

Embodiment Construction

[0027] figure 1 is a block diagram showing a wireless communication system. figure 1 It may be a 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) / LTE-Advanced (LTE-A) network structure. E-UTRAN (Evolved-UMTS Terrestrial Radio Access Network) includes at least one base station (BS) 20 that provides user equipment (UE) 10 with a user plane and a control plane. The UE can be fixed or mobile, and other terms such as MS (mobile station), UT (user terminal), SS (subscriber station), MT (mobile terminal), wireless, etc. may be used. The BS 20 may be a fixed station that communicates with the UE 10, and other terms may be used, such as e-NB (Evolved-NodeB), BTS (Base Transceiver System), access point, and the like. There are one or more cells within the coverage area of ​​the BS 20 . An interface for transmitting traffic or controlling traffic can be used between a plurality of BSs 20 . The BSs 20 are interconnected with each other through the X2 interface. The...

Abstract

A method and apparatus of releasing a radio bearer in a wireless communication system is provided. After determining to release a radio link control (RLC) entity and a packet data convergence protocol (PDCP) entity, the RLC entity is released after delivering an RLC service data unit (SDU) extracted according to a release request of the RLC entity to the PDCP entity. A first PDCP SDU obtained by processing the RLC SDU is stored in a reception buffer at the PDCP entity. The PDCP entity is released after delivering the first PDCP SDU stored in the reception buffer to a higher layer.

Description

technical field [0001] The present invention relates to wireless communication, in particular to a method and apparatus for releasing a radio bearer in a wireless communication system. Background technique [0002] Wireless communication systems are widely used to provide voice services or packet services. Multiple-access systems support multi-user communications by sharing the available system resources. Examples of multiple-access systems include code division multiple access (CDMA) systems, frequency division multiple access (FDMA) systems, time division multiple access (TDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, and the like. [0003] 3rd Generation Partnership Project (3GPP) release 8 introduced 3GPP Long Term Evolution (LTE) as an evolution of the Universal Mobile Mobile Telecommunications System (UMTS). 3GPP LTE uses OFDMA in the downlink and Single Carrier-FDMA (SC-FDMA) in the uplink. 3GPP LTE employs Multiple Input Multiple Out...
