Abstract

Techniques for transmitting voice/data and packet data services such that packet data transmissions have less impact on voice/data transmissions. In one aspect, voice/data and packet data can be multiplexed within a transmission interval such that the available resources are efficiently utilized. In another aspect, the amount of variation in the total transmit power from a base station is controlled to reduce degradation to transmissions from this and other base stations. In a specific method for concurrently transmitting a number of types of data, a first data type (e.g., voice, overhead, and some data) and a second data type are respectively processed in accordance with first and second signal processing schemes to generate first and second payloads, respectively. First and second partitions are then defined in a transmission interval. The first and second payloads are time multiplexed into the first and second partitions, respectively, and the multiplexed payloads are transmitted.

Claims

1. A method for receiving a time division multiplexed (TDM) transmission, the method comprising:

demultiplexing a first payload transmitted in a first partition of a transmission interval of the TDM transmission, wherein the TDM transmission further includes a second payload transmitted in a second partition of the transmission interval; and

processing the first payload in accordance with a first signal processing scheme.

2. The method of claim 1, further comprising:

demultiplexing the second payload transmitted in the second partition of the transmission interval; and

processing the second payload in accordance with a second signal processing scheme.

3. The method of claim 1, further comprising:

receiving signaling indicative of the first and second partitions in the transmission interval.

4. A receiver unit in a communication system operative to receive one or more types of data in a time division multiplexed (TDM) transmission, the receiver unit comprising:

a receiver operative to receive and process the TDM transmission to provide a plurality of symbols;

a demultiplexer operative to receive and demultiplex a first payload of symbols sent in a first partition of a transmission interval for the TDM transmission, wherein the TDM transmission includes at least one other payload sent in at least one other partition of the transmission interval; and

a first data processor operative to receive and process the first payload in accordance with a first signal processing scheme to generate first decoded data.

5. The receiver unit of claim 4, further comprising:

a second data processor operative to receive and process a second payload in accordance with a second signal processing scheme to generate second decoded data.
