    Abstract: A method of data packet communication. The method includes the step of transmitting CQI in response to an inactive state. The step of transmitting CQI may include receiving an incoming signal associated with one or more real time duplex services, such as voice over IP ("VoIP"), gaming and/or two-way video applications, for example. Thereafter, the method includes the step of pausing the transmission of CQI in response to a break period in the inactive state. The break period may be initiated by transmitting an outgoing signal associated with at least one real time duplex service, such as voice over IP ("VoIP"), gaming and/or two-way video applications, for example. Moreover, the step of pausing may include receiving a do-not-transmit signal to initiate the break period.

    Abstract: A method for reducing the peak-to-average power ratio (PAPR) in an OFDM based wireless system is disclosed herein. The reduced PAPR may be achieved by appropriately selecting subpackets for transmission. For example, a scheduler may elect to sequentially transmit the subpackets in an order related to the PAPR of each of the subpackets until at least one of the subpackets is properly received. In one embodiment of the instant invention the order of transmission is selected to be from lowest to highest PAPR.

    Abstract: In an embodiment, a composite signaling message part is formed to include at least two segments (500), each segment (500) including data identifying a different user equipment (UE). In another embodiment, a different portion of a composite signaling message part is transmitted over at least one same time slot in each of the shared control channels; the part including at least two segments (510, 530) and each segment (510, 530) including data identifying a different user equipment (UE). In these embodiments, the part further includes a cyclic redundancy code (550), (CRC) generated by jointly encoding the at least two segments (510, 530). In a further aspect of the method, more than one shared control channel jointly carrying a signaling message are power controlled such that each shared control channel carrying more data associated with one of the UEs is power controlled in accordance with that UE. In a still further embodiment, the channelized code information for a dedicated control channel is divided between first and second parts of the shared control signals.

    Abstract: An adaptive incremental redundancy (i.e., Hybrid ARQ) method is described for retransmitting information in a communication channel of a wireless communication system. More specifically, code multiplexing is used within fixed length frames in order to change the number of codes, modulation, and coding on retransmissions to provide the desired redundancy for successful decoding. The operation of adaptive Hybrid ARQ in the code domain also provides finer granularity in which to efficiently transmitting redundancy. In one illustrative embodiment, a method for retransmitting information in a communication channel having a plurality of fixed length frames each divided into a plurality of time slots of equal duration includes the step of code multiplexing a retransmission of a previous transmission within one of the fixed length frames using one or more of a plurality of codes. The number of codes used for the retransmission is variable based on the condition of the communication channel.

    Abstract: A method for reliably transmitting signaling information is provided. One type of signaling information is transmitted over a primary control channel. The signaling information that is to be transmitted over the primary control channel is defined as a set of particular information. Other signaling information are conveyed over a secondary control channel. Prior to transmission, the information to be conveyed over the secondary channel is scrambled in accordance with a particular scrambling procedure that indicates the information that is to be sent over the primary control channel. The scrambling is thus used to encode the information content of the primary control channel into the information of the secondary control channel thereby further protecting the integrity of the information being conveyed over both control channels.

    Abstract: A variable length sequence number is used to identify data units in a communication channel. The sequence number associated with the most recent data that has been received successfully and the sequence number expected with the next new data message to be received are examined to determine the minimum size sequence number necessary to unambiguously identify to the transmitter incorrectly received data that must be retransmitted in a later message. The receiver provides the transmitter with the sequence number associated with the last successfully received byte of data and the sequence number associated with the next expected byte of data. The receiver communicates this information to the transmitter using a NAK control message. The transmitter then uses the sequence number of the next byte of data to be transmitted and the information received in the control message from the receiver to determine the smallest number of bits necessary to represent the sequence numbers for both data transmissions and the retransmission of data that was not received properly by the receiver.
