Embodiment Construction

[0051] In the figures, the same reference numerals are used for similar or corresponding elements.

[0052] figure 1 A Universal Mobile Telecommunications System UMTS network 100 in which the method and apparatus can be implemented is schematically illustrated. It should be noted, however, that a person skilled in the art will readily perform implementations in other similar communication systems involving data transmission between nodes.

[0053] exist figure 1 , a UMTS 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 of which is coupled to a set of one or more neighboring nodes in the form of Node Bs 104a, 104b. Each Node B 104 is responsible for a given geographical radio cell, and the controlling RNC 105 is responsible for routing user and signaling data between that Node B 104 and the core network 102 . All RNCs 105 ...

Abstract

The proposed technique relates to a method for transferring information from a node to a user equipment UE in an HSPA system. The method comprises the steps of: obtaining (S1) rank information and modulation information related to a four-branch MIMO system. The method further comprises the steps of: combining (S2) rank information and modulation information related to a four-branch MIMO system into a bit pattern, and using the combined rank information and modulation information related to a four-branch MIMO system as said bit pattern Sent (S3) to the UE in a control channel. In this way, a power efficient solution is provided for transferring information related to a four-branch MIMO system in a control channel from a node to a UE in an HSPA system.

Description

technical field [0001] The field of the present disclosure is that of Multiple-Input Multiple-Output MIMO transmission in High Speed ​​Packet Access HSPA mobile communication systems. More specifically, the proposed technology relates to a method for transferring information from a node to a user equipment UE and a corresponding node, and a method for receiving and processing information from a node and a corresponding UE, and in an HSPA system for A method for bit-mapping information of a control channel and a corresponding bit-mapping device, and a method for processing information of such a control channel and a corresponding device. Background technique [0002] HSPA is typically based on High Speed ​​Downlink Packet Access HSDPA in the downlink and Enhanced Uplink EUL in the uplink. Enhanced Uplink is also sometimes referred to as High Speed ​​Uplink Packet Access HSUPA. [0003] HSDPA is an enhancement to WCDMA that provides a smooth evolution path to higher data rat...
