摘要： Embodiments of the invention provide for allocating spectrum in a wireless communication system that supports simultaneously at least a first mode of operation and a second mode of operation. Logic is arranged for determining a proportion of spectrum required for the wireless communication unit to operate simultaneously in both the first mode of operation and the second mode of operation. Logic for allocating spectrum allocates a temporary guard band between a first portion of spectrum for the first mode of operation and a second portion of spectrum for the second mode of operation for use whilst the wireless communication unit operates simultaneously in the first mode of operation and second mode of operation.

摘要： A method and arrangement (100) for PRACH burst channel detection in a UTRA TDD wireless communication system in which training sequences are constructed from a single periodic base code. Unwanted cross-correlation peaks, having magnitude less than correlation peaks, are removed (440) from the correlator outputs, maintaining optimal signal-to-noise ratio of the channel estimates, providing a low probability of false detection, and extending the cell size of a CDMA network to that determined by the guard period duration. The cell size can be extended further by ensuring that no transmissions are scheduled for the timeslot subsequent to that in which the channel estimation bursts are scheduled.

摘要： A cellular communication system comprises a Multiple-In Multiple-Out, MIMO, transmitter (101) and receiver (103). The MIMO transmitter (101) comprises a message generator (303) for generating MIMO messages comprising selected training sequences and transceivers (305, 307, 309) transmitting the messages on a plurality of antennas (311, 313, 315). The training sequences are selected by a midamble selector (317) from a set of training sequences in response to an associated antenna on which the message is to be transmitted. The set of training sequences is associated with the cell of the MIMO transmitter and comprises disjoint subsets of training sequences for each of the plurality of antennas. The receiver (103) comprises a transmit antenna detector (419) which determines which antenna of the MIMO transmitter the message is transmitted from in response to the training sequence of the received message.

摘要： An efficient scheme for CDMA coding constructs codes by generating longer code sequences (430) via concatenation, from an existing set of short sequences (410, 420). The sequences may be spreading, scrambling and or training or channel estimation (such as midamble) sequences. The invention allows extension of sequences without performing an exhaustive search for sequences with optimal desired properties, as well as extension of the sequence duration to improve the detection of wanted signals via the use of a conventional matched filter, a multi-user detector or an adaptive filter/equaliser.

摘要： A telecommunications system communicating data to/from one or more terminals and a network, including one or more transmitters operable to transmit first and second carriers over respective first and second frequency bandwidths. During a first time period the transmitters can transmit data receivable by first and second classes of terminals on the first and second carriers. During a second different time period, the transmitters can transmit data to the second terminal class on the first and second carriers in combination. A data transmission format on the first carrier is incompatible with a user data transmission format on the second carrier, during the first time period, and the transmitters can transmit control data on the first carrier in the first time period receivable by the second terminal class to enable the second terminal class to maintain synchronization with the first carrier during the first time period.
