Abstract

Transmitter(s) (34), radio base station nodes (38) comprising transmitter(s), and methods of operating transmitter(s) / radio base station(s) involve handling discontinuous transmission indication bits, particularly when transmitting using a 16 QAM signal point constellation having an I-branch and a Q-branch (for a quadruple of bits comprising two I-branch bits, i1 and i2, and two Q-branch bits q1 and q2). The transmitter(s) (34) and the radio base station nodes (28) comprised thereof are operated to perform a Multimedia Broadcast Multicast Service over Single Frequency Network (MBSFN) transmission wherein the MBSFN transmission comprises mapping data to a Secondary Common Control Physical Channel (SCCPCH).

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application 61 / 138,205, filed December 17, 2008, entitled "Methods For Handling DTX Bits In Connection with 16QAM," the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to telecommunications, in particular to a baseband processing method and device in a transmitter, which are used for processing discontinuous transmission indication bits when transmitting using a 16QAM signal point constellation diagram. Background technique [0004] In a typical cellular radio system, radio terminals (also known as mobile stations and / or user equipment units (UEs)) communicate via a radio access network (RAN) with one or more core networks. A radio access network (RAN) covers a geographical area divided into cell areas, each served by a base station, such as a radio base station (RBS), also referred to as a "N...
