Abstract
A transmission of information from a secondary to a primary node occurs in a plurality of N logical time durations. The transmission from the secondary to primary node in a wireless network (100) is performed by first receiving an allocation of M>1 reverse link channels for transmission of N>0 information elements. N information elements are produced. A group of K (possibly only one) reverse link channels is selected from the M allocated reverse link channels using at least one of the N produced information elements wherein the group of K reverse link channels comprises at least one channel such that 0<K<M. A signal is produced using the produced information elements and the produced signal is transmitted on the selected group of K reverse link channels. Embodiments of the invention apply to transmission of ACKNAK and SRI. FIG. 1

Claim
1. A method for transmitting in a wireless communication system, comprising: receiving an allocation of M>1 reverse link channels for transmission of N>0 information elements; producing the N information elements; selecting a group of K reverse link channels from the M allocated reverse link channels, using at least one of the N produced information elements, wherein the group of K reverse link channels comprises at least one channel, such that 0
2. The method of Claim 1, wherein receiving an allocation of M>1 reverse link channels comprises: receiving a signal on at least one forward link channel element (CE) indexed Ll; and deriving at least a first allocated reverse link channel using the index Ll.
3. The method of Claim 2, wherein receiving an allocation of M>1 reverse link channels comprises: combining an identity of a wireless node with the signal received on the forward link CE indexed Ll to produce a combined signal; producing an error-check by performing error-detection on the combined signal; and wherein if the error-check is negative, Ll is used to derive at least the first allocated reverse link channel.
4. The method of Claim 3, wherein receiving an allocation of M>1 reverse link channels further comprises: receiving a signal on at least one forward link CE indexed L2; and deriving at least a second allocated reverse link channel using the index L2.
5. The method of Claim 1, wherein receiving an allocation of M>1 reverse link channels comprises: receiving a signal on at least a forward link channel element (CE) indexed Ll and a forward link CE indexed L2; combining an identity of a wireless node with the received signal to produce a combined signal; producing an error-check by performing error-detection on the combined signal; and if the error-check is negative, then Ll is used to derive at least a first allocated reverse link channel and L2 is used to derive at least a second allocated reverse link channel.
6. The method of Claim 2, wherein:', 'N information elements are N binary - valued quantities (N bits); the group of K reverse link channels equals exactly one reverse-link channel (K = I); selecting a group of K = 1 reverse link channels is performed using log2(M) bits; and producing a signal is performed using N - log2(M) bits.
7. The method of Claim 1, wherein producing the N information elements comprises: receiving at least a first data packet; and producing first ACKNAK information by performing error detection on the received first data packet, wherein the first ACKNAK information is the first information element.
8. The method of Claim 7, wherein producing the N information elements further comprises producing a scheduling request indicator (SRI), wherein a second information element is the SRI.
9. The method of Claim 7, wherein producing the N information elements further comprises: receiving a second data packet; and producing a second ACKNAK information by performing error detection on the received second data packet, wherein the second ACKNAK information is a second information element
10. The method of Claim 1, wherein producing a signal using at least one of the N produced information elements comprises producing a reference signal (RS) having Pl time durations; and wherein producing the reference signal for a Q-th logical time duration comprises: producing a first sequence; producing a second sequence; and multiplying the entire first sequence with the Q-th element of the second sequence; wherein 1 < Q < Pl
11. The method of Claim 1, wherein producing a signal using at least one of the N produced information elements further comprises producing a data-bearing signal having P2 logical time durations; and wherein producing data-bearing signal for R- th logical time duration comprises: producing a third sequence; producing a fourth sequence; and multiplying the entire third sequence with the R-th element of the fourth sequence; wherein 1 < R < P2
12. An apparatus for transmitting in a wireless communication system, comprising: circuitry for receiving an allocation of M>1 reverse link channels for transmission of N>0 information elements; coupled to circuitry for producing the N information elements; coupled to circuitry for selecting a group of K reverse link channels, from the M allocated reverse link channels, using at least one of the N produced information elements; wherein the group of K reverse link channels comprises at least one channel, such that 0
14. The apparatus of Claim 13, wherein the circuitry for producing N information elements comprises circuitry for producing a scheduling request indicator (SRI)
15. The apparatus of Claim 14, wherein the circuitry for receiving an allocation of M>1 reverse link channels comprises: circuitry for receiving an allocation of the first reverse link channel; and circuitry for receiving an allocation of the second reverse link channel; and wherein the circuitry for selecting a group of K=I reverse link channels operates by selecting the second allocated reverse link channel whenever SRI is positive and selecting the first allocated reverse link channel whenever SRI is negative.']
