摘要： Method and Apparatus for Processing Shared Sub-packets in a Communication System are disclosed. A communication system providing both voice and data services allows for a plurality of subscriber station to share a data sent in a unit of a forward traffic channel. To provide information required by the subscriber stations to determine that a unit of the forward traffic channel is shared, and to correctly decode the data, different control channel structures are described. Additionally, the control channel structures provides for more efficient signaling of code channel assignment.

摘要： The contents of a counter at a remote station is used to select a Walsh cover, which is used to cover the acknowledgment or negative acknowledgment bits sent on a new reverse acknowledgment channel (R-ACKCH). In the new reverse acknowledgment channel, the value of the acknowledgment bits for the broadcast transmissions is used to select the Walsh code sequence that covers the acknowledgment bit for the dedicated transmissions. When a base station receives an acknowledgment message from the remote station, the base station checks the Walsh cover of the message and extracts the embedded counter content. If the embedded counter content of the received acknowledgment or negative acknowledgment differs from the local counter value, the base station determines that a synchronization problem occurred, such that the remote station is not operating with the current transmission format information. Hence, the counter values act as the sequence identifiers of the Walsh masks.

摘要： Methods and apparatus are presented for acknowledging broadcast transmissions. An acknowledgment channel is designed for acknowledging the success or failure of a transmission on a dedicated channel and on a broadcast channel. Acknowledgments are generated based on whether a new orthogonal space is sent to a remote station or not. Moreover, an acknowledgment to the broadcast transmission is generated when an acknowledgment is needed for a dedicated transmission. The two acknowledgments are combined and sent to a base station.

摘要： Methods and apparatus are presented for implementing an improved Control-Hold Mode that reduces the load of the reverse link and reduces the battery consumption of remote stations. While a remote station is in the improved Control-Hold Mode, the circuitry that monitors the forward packet data channels and the associated control channels are turned off. Since the forward packet data channels and their associated control channels are not monitored, the operations of the reverse channels can be gated off to predetermined duty cycles, or set on intermittent transmission modes, or shut down completely. Transitions from the Control-Hold Mode to the Active Mode can be initiated by the remote station or by a base station. When a transition is initiated by a remote station, the remote station transmits a signaling message to a serving base station and then starts operating the feedback channels before actually receiving forward link signals.

摘要： Techniques are provided for single carrier optimization. For example, there is provided a method that involves, in a subframe of a radio spectrum, allocating a first set of resource elements (REs) for multimedia broadcast over a single frequency network (MBSFN) transmissions, each symbol corresponding to each RE of the first set having a first cyclic prefix (CP) type. The method may involve allocating a second set of REs for unicast transmissions, each symbol corresponding to each RE of second set having a second CP type. The method may involve determining whether the first CP type and the second CP type are the same. The method may involve, in response to the first CP type and the second CP type being the same, combining the MBSFN transmissions and the unicast transmissions in the subframe according to the allocated first and second sets of REs.

摘要： Interference on pilot signals and on data tones can be mismatched. Different types of interference estimates perform differently based on how the mismatch occurs. The resulting interference estimate may thus be inaccurate. Interference estimates based on pilot signals and also on data tones can both be evaluated for reliability. The more reliable of the two can then be selected. If the data tones estimate is selected, the estimate can be calculated from covariance matrices or from traffic-to-pilot ratios.

摘要： In a wireless communication system a method for combination transmission of packet data and low delay data. In one embodiment a parallel signaling channel provides a message to receivers indicating a target recipient of packet data. The message also identifies the transmission channels used for packet data transmissions. Each receiver may then selectively decode only packets where the message identifies the receiver as a target recipient. The data packets stored in a buffer are ignored if the target recipient is another mobile unit. In one embodiment, the message is sent concurrently with the data packet on a parallel channel. In one embodiment, the message is punctured into the high rate packet data transmission.
