Abstract
Abstract The invention relates to a TDD method between a base station and at least one mobile station using a Logical Control Channel (LCCH) and at least one Traffic Channel (TCH). In order to increase the channel capacity for conversations which are to be carried out, the Logical Control Channel (LCCH) is interrupted, and a further Traffic Channel (TCH) is set up in a time slot assigned to said Logical Control Channel (LCCH). As soon as one of the Traffic Channels (TCH) is switched off again, the Logical Control Channel (LCCH) is set up once again in the time slot of said Traffic Channel (TCH).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
77 words
TDD method between a base station and at least one mobile station using a logical Control Channel (LCCH) and at least a first traffic channel (TCH), wherein the Logical Control Channel (LCCH) is interrupted and is carried out in a time slot (B, B') assigned to it for setting up a further Traffic Channel (TCH), and synchronization signals (Synch) are sent on the first Traffic Channel (TCH) while the further Traffic Channel (TCH) is being set up.
Claim 2
Dependent Claim
77 words
TDD method between a base station and at least one mobile station using a logical Control Channel (LCCH) and at least a first traffic channel (TCH), wherein the Logical Control Channel (LCCH) is interrupted and is carried out in a time slot (B, B') assigned to it for setting up a further Traffic Channel (TCH), and synchronization signals (Synch) are sent on the first Traffic Channel (TCH) while the further Traffic Channel (TCH) is being set up.
Claim 3
Dependent Claim
29 words
