Problems solved by technology

Additionally, the medium access control high-speed (MAC-hs) layer in the base station and the medium access control (MAC) in the wireless transmit / receive unit (WTRU) do not support segmentation of service data units (SDUs) from higher layers
These limitations can lead to performance limitations, especially as High Speed ​​Packet Access (HSPA) moves toward higher data rates

Abstract

A method and apparatus for supporting uplink (UL) protocol changes, including reconfiguring a Medium Access Control (MAC) protocol. Flush the Hybrid Automatic Repeat Request (HARQ) process and perform a MAC-e / es reset.

Description

technical field [0001] This application relates to wireless communications. Background technique [0002] In 3rd Generation Partnership Project (3GPP) Release 6 (R6) systems, the Radio Link Control (RLC) layer in Answered Mode (AM) operates with a fixed Protocol Data Unit (PDU) size. Additionally, the medium access control high-speed (MAC-hs) layer in the base station and the medium access control (MAC) in the wireless transmit / receive unit (WTRU) do not support segmentation of service data units (SDUs) from higher layers. These limitations can lead to performance limitations, especially as High Speed ​​Packet Access (HSPA) moves towards higher data rates. [0003] In order to achieve higher data rates and reduce protocol overhead and padding, many new features for Layer 2 (L2) protocols were introduced in Release 7 of the 3GPP specifications. Variable RLCPDU size and MAC segmentation in the downlink are among the concepts introduced. It is also proposed to enhance L2 ope...
