Method and arrangement for transmissions in VAMOS capable wireless communication systems
First Claim
1. A method for transmitting information from a radio base station node to a first mobile station and a second mobile station paired on and sharing a same carrier frequency, Time Division Multiple Access (TDMA) frame, and time slot in a wireless communication system, wherein said first and second mobile stations are allocated on a first and second Voice services over Adaptive Multi-user channel on One Slot (VAMOS) sub-channel, respectively, said method comprising:
- transmitting a Gaussian Minimum Shift Keying (GMSK) modulated Slow Associated Common Control Channel (SACCH) burst of a SACCH block in a predetermined time slot and TDMA frame on one of said first and second VAMOS sub-channels;
simultaneously muting the SACCH burst in the other of said first and said second VAMOS sub-channels in said predetermined time slot and TDMA frame; and
performing said transmitting and said simultaneously muting alternately on both of said first and second VAMOS subchannels.

Abstract
A method for transmitting information from a radio base station node to a first mobile station and a second mobile station is disclosed herein. The first and second mobile stations are paired on and share a same carrier frequency, TDMA frame, and time slot in a wireless communication system. Further, the first and second mobile stations are allocated on a first and second VAMOS sub-channel, respectively. The method includes transmitting a GMSK modulated SACCH burst of a SACCH block in a predetermined time slot and TDMA frame on one of the first and second VAMOS sub-channel. The method further includes simultaneously muting the other of the first and second VAMOS sub-channels in the predetermined time slot and TDMA frame.

11. An apparatus in a radio base station node, for transmitting information to a first mobile station and a second mobile station paired on and sharing a same carrier frequency, Time Division Multiple Access (TDMA) frame, and time slot in a wireless communication system, wherein said first and second mobile stations are allocated on a first and second Voice services over Adaptive Multi-user channel on One Slot (VAMOS) sub-channel respectively, said apparatus comprising:
-
a Gaussian Minimum Shift Keying (GMSK) modulating Slow Associated Common Control Channel (SACCH) unit configured to transmit a GMSK modulated SACCH burst in a predetermined time slot and TDMA frame on one of said first and second VAMOS sub-channels; and a muting unit configured to simultaneously mute the SACCH burst in the other of said first and said second VAMOS subchannels on the same time slot, wherein the GMSK modulating SACCH unit and the muting unit are configured to transmit the GMSK modulated SACCH burst and to simultaneously mute the SACCH burst alternately on both of the first and second VAMOS subchannels.
