Embodiment Construction

[0023] The 3rd Generation Partnership Project (3GPP) is a collaboration among telecommunications association groups aimed at defining globally applicable third generation (3G) mobile phone specifications. 3GPP Long Term Evolution (LTE) is a 3GPP project aimed at improving the Universal Mobile Telecommunications System (UMTS) mobile telephony standard. 3GPP may define specifications for next generation mobile networks, mobile systems and mobile devices.

[0024] In 3GPP LTE, a mobile station or device may be referred to as "User Equipment" (UE). A base station may be referred to as an evolved Node B (eNB). A semi-autonomous base station may be called a Home eNB (HeNB). Therefore, a HeNB may be an example of an eNB.

Abstract

A method for providing multiple-user multiple-input and multiple-output in a high-speed packet access system is described. Channel quality indicators are received from a plurality of dual stream capable wireless communication devices. A preferred beam and a secondary beam are determined for each wireless communication device using the channel quality indicators. Wireless communication devices with preferred beams orthogonal to each other are paired. A wireless communication device pair is selected. Data streams for the selected wireless communication device pair are scheduled in the same transmission time interval using an orthogonal variable spreading factor code.

Description

[0001] related application [0002] This application is related to, and claims priority from, US Provisional Patent Application No. 61 / 262,105, filed November 17, 2009, entitled "MULTI-USER MIMO FOR HSPA." technical field [0003] In general, the present invention relates to wireless communication systems. In particular, the present invention relates to systems and methods for Multi-User Multiple-Input and Multiple-Output (MU-MIMO) for High Speed ​​Packet Access (HSPA) systems. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, data, and so on. These systems may be multiple-access systems capable of supporting simultaneous communication with multiple terminals and one or more base stations. [0005] In all communication systems, the problem that must be dealt with is fading or other interference problems. Herein lies the problem of decoding the received signal. One way t...
