MOBILE COMMUNICATIONS SYSTEM
First Claim
1. A method of operating a digital mobile radio communications system in which pilot symbols are used for channel equalisation and in which synchronisation symbols are used to indicate burst timings, the method comprising:
- using a sequence of pilot symbols, a sequence of synchronisation symbols, or a sequence of pilot symbols and synchronisation symbols in a transmission to indicate to a receiver the presence of stealing in the transmission.

Abstract
A scheme for indicating the presence of stealing or other information in a digital mobile radio communications system. A sequence of pilot symbols and/or synchronisation symbols that can be distinguished from a normal sequence of pilot symbols and/or synchronisation symbols is included in a transmission to indicate the presence of stealing. A receiver determines whether a received transmission includes the stealing sequence or the normal sequence and decodes the transmission accordingly.

-
determining whether a received transmission includes a sequence of pilot symbols, a sequence of synchronisation symbols, or a sequence of pilot symbols and synchronisation symbols indicative of the presence of stealing in the transmission; and if it is determined that a sequence of pilot symbols, a sequence of synchronisation symbols, or a sequence of pilot symbols and synchronisation symbols indicative of the presence of stealing is present in the received transmission, identifying the presence of stealing in the transmission and decoding the transmission accordingly. - View Dependent Claims (8, 9, 10)

31. A computer program element comprising computer software code portions which when the program element is run on a data processor performs a method of operating a digital mobile radio communications system in which pilot symbols are used for channel equalisation and in which synchronisation symbols are used to indicate burst timings, the method comprising:
using a sequence of pilot symbols, a sequence of synchronisation symbols, or a sequence of pilot symbols and synchronisation symbols in a transmission to indicate to a receiver the presence of stealing in the transmission.
