Problems solved by technology

[0005] While this may not necessarily cause a protocol failure, it is detrimental as it may result in an inefficient use of available air interface resources in existing solutions, as this redundant data may need to be sent to the UE before it can be discarded

Embodiment Construction

[0017] figure 1 A mobile communication system in the form of a cellular network 100 in which the method and apparatus may be implemented is schematically shown. figure 1 The cellular network 100 in is illustrated by the Universal Mobile Telecommunications System UMTS. It should be noted, however, that those skilled in the art will readily perform implementations in other similar communication systems involving the transmission of encoded data between nodes.

[0018] exist figure 1 , a cellular network 100 includes a core network 102 and a UMTS terrestrial radio access network UTRAN 103 . The UTRAN 103 comprises a plurality of nodes in the form of Radio Network Controllers RNC 105a, 105b, each coupled via a so-called transport network TN 112 to a set of neighboring nodes in the form of one or more Nodes B 104a, 104b, 104c. Each Node B 104 is responsible for a radio cell of a given geographical area, and the controlling RNC 105 is responsible for routing user data and signali...

Abstract

Explicit discard indications are used that allows a radio network controller (105), when operating in a multi-point High Speed Downlink Packet Access, HSDPA, scenario, to send data to a user equipment (106) via plural radio base stations (104) while reducing the risk for unnecessary duplicate data to be sent over the Uu interface between the radio base stations and the user equipment.

Description

technical field [0001] The present disclosure relates to handling redundant data communicated between different entities in a radio access network, such as radio base stations and radio network controllers. Background technique [0002] The 3rd Generation Partnership Project 3GPP is currently working on specifying support for MP HSDPA (Multipoint High Speed ​​Downlink Packet Access) in Release 11. When MP HSDPA is employed, downlink data is sent to a UE (User Equipment, also called mobile / wireless terminal) via two Node Bs (herein also called Radio Base Station, RBS) instead of one Node B. The UE will thus receive data via two MAC-hs (HSDPA medium access control protocol handling fixed size RLC data) or MAC-ehs (HSDPA medium access control protocol handling fixed or variable size RLC data) streams, and Data is reordered at the RLC (Radio Link Control) level for delivery to higher layers. It should be noted that various terms have been used to describe this functionality in...
