摘要： An arrangement and method for channel mapping in a UTRA TDD HSDPA wireless communication system by applying interleaving functions in first (530) and second (540) interleaving means to a bit sequence to produce symbols for mapping to physical channels, the first and second interleaving means being arranged to map symbols from respectively systematic and parity bits in a predetermined scheme, e.g., mapping symbols in a forward direction when a channel has an even index number, and in a reverse direction when a channel has an odd index number. The symbols may comprise bit-pairs, each of a systematic bit and parity bit. Systematic bits are preferably mapped to high reliability bit positions in TDD HSDPA, achieving a performance gain of between 0.2dB and 0.5dB. The forwards/reverse mapping allows a degree of interleaving that improves system performance in fading channels or channels disturbed by short time period noise or interference.

摘要： An apparatus 300 for a cellular communication system ( 100 ) comprises a buffer ( 303 ) which receives data for transmission over an air interface ( 115 ). The buffer ( 303 ) is coupled to a scheduler ( 305 ) which schedules the data and allocates the physical resource of the air interface ( 115 ). The transmissions are performed using a retransmission scheme such as a Hybrid-Automatic Repeat reQuest scheme. A load processor ( 309 ) determines a load characteristic associated with the scheduler ( 305 ) and a target controller ( 311 ) sets a target parameter for the retransmission scheme in response to the load characteristic. Specifically, a block error rate target may be set in response to a load level of a cell or plurality of cells. A transmission controller ( 307 ) sets a transmission parameter for a transmission in response to the target parameter and a transmitter ( 301 ) transmits the data using the transmission parameter. Accordingly, an operating point of the retransmission scheme may be dynamically adjusted thereby reducing overall latency.

The first and second modes of TDD operation are dissimilar and communications cover substantially the same geographic area.

摘要： In a CDMA system ( 100 ), two chip rates in a TDD cell are supported by: transmitting signals in the system in a frame ( 400 ) having a plurality of timeslots; operating at least a first one ( 0 - 8 ) of the plurality of timeslots in the frame at a lower chip rate; and operating at least a second one ( 9 - 14 ) of the plurality of timeslots in the frame at a higher chip rate. This provides the following advantages: provides backwards compatibility of a network including higher chip rate functionality with existing lower chip rate user equipment; allows greater network capacity during the transition phase from a low chip rate network to a high chip rate network; and allows a network operator with a high chip rate network to provide service to roaming users from low chip rate networks.

摘要： A User Equipment, UE, (101) of a cellular communication system (100) transmits scheduling assistance data to a base station (105) comprising a base station scheduler (209) which schedules packet data. The scheduling assistance data relates to packet data communication of the UE (101). The scheduling assistance data is generated by a scheduling assistance data generator (223) coupled to a packet data transmit buffer (221) associated with the packet data transmission. A first transport channel controller (217) allocates other data to a first transport channel and a retransmission controller (219) operates a retransmission scheme for this transport channel. A second transport channel controller (225) allocates the scheduling assistance data to a signalling transport channel and a transport channel multiplexer (227) combines the two transport channels as multiplexed channels on a single physical resource. The transmission reliabilities for the retransmission and non-retransmission transport channels may be individually optimised.
