    摘要: The application relates to a method for communication from a second mobile station to a base station or vice versa. In a given multiframe, a first SACCH slot associated with the second mobile station is communicated (i.e. received or transmitted or both) via the second VAMOS subchannel. In the same multiframe, a redundant second SACCH slot associated with the second mobile station is communicated. The communicating step is performed either by the second mobile station or by the base station. The second SACCH slot may be communicated via the second VAMOS subchannel, in case the second VAMOS subchannel is in DTX mode. In an alternative embodiment, the second SACCH slot may be communicated via a first VAMOS subchannel, in case the first VAMOS subchannel is in DTX mode, wherein the first and second VAMOS subchannels share a common time slot and have the same carrier frequency. Both embodiments may be combined: I.e. in case the second VAMOS subchannel is in DTX mode, the second SACCH slot is communicated via the second VAMOS subchannel, and in case the first VAMOS subchannel is in DTX mode, the second SACCH slot may be communicated via the first VAMOS subchannel.

    摘要: The present disclosure provides for the construction and use of a set of Zero-Correlation-Zone (ZCZ) Concatenated Complementary Pair (CCP) sequences with zero-correlation-zone range greater than one or with zero-correlation-zone range equal to one and the sequence set size greater than two. Complementary pair sequences A and B are selected and, for each member of the set of ZCZ CCP sequences, sign sequences pA and pB are combined with the complementary pair sequences to form a member ZCZ CCP sequence of the set. A ZCZ CCP sequence modified by propagation over a communication channel may be identified by cross-correlation with ZCZ CCP sequences of the set. A set of sign sequences may be constructed by recursive expansion from an initial set or found by a computer search. The sequences may be used in a transceiver of a portable electronic device or other communication device.

    摘要: Methods and apparatus to secure communications in a mobile network are disclosed. An example method disclosed herein comprises randomizing a first set of bits associated with information to be communicated over a slow associated control channel by applying a scrambling factor to generate a set of scrambled bits equal in length to the first set of bits. Another example method disclosed herein comprises concatenating a set of error detection bits with a set of information bits associated with information to be transmitted over a slow associated control channel to generate a set of coded bits, and shuffling the set of coded bits to generate a set of shuffled bits.
