The present invention is directed, in general, to wireless communication systems and, more specifically, to a Single-Carrier Frequency Division Multiple Access (SC-FDMA) communication system and is further considered in the development of the 3.sup.rd Generation Partnership Project (3GPP) Evolved Universal Terrestrial Radio Access (E-UTRA) long term evolution (LTE).

In Equation (1), L is the length of the CAZAC sequence, n is the index of a particular element of the sequence n={0, 1, 2 . . . , L-1}, and finally, k is the index of the sequence itself. For a given length L, there are L-1 distinct sequences, provided that L is prime. Therefore, the entire family of sequences is defined as k ranges in {1, 2 . . . , L-1}. However, the CAZAC sequences used for PUCCH signaling need not be generated using the exact above expression as it is further discussed below.
For CAZAC sequences of prime length L, the number of sequences is L-1. As the RBs are assumed to include an even number of sub-carriers, with 1 RB includes 12 sub-carriers, the sequences used to transmit the ACK/NAK and RS can be generated, in the frequency or time domain, by either truncating a longer prime length (such as length 13) CAZAC sequence or by extending a shorter prime length (such as length 11) CAZAC sequence by repeating its first element(s) at the end (cyclic extension), although the resulting sequences do not fulfill the definition of a CAZAC sequence. Alternatively, CAZAC sequences can be generated through a computer search for sequences satisfying the CAZAC properties.
In order for the multiple CAZAC sequences 810, 830, 850, 870 generated correspondingly from multiple cyclic shifts 820, 840, 860, 880 of the same root CAZAC sequence to be orthogonal, the cyclic shift value .quadrature. 890 should exceed the channel propagation delay spread D (including a time uncertainty error and filter spillover effects). If T.sub.S is the duration of one symbol, the number of cyclic shifts is equal to the mathematical floor of the ratio T.sub.S/D. The cyclic shift granularity equals an element of the CAZAC sequence. For a CAZAC sequence of length 12, the number of possible cyclic shifts is 12 and for symbol duration of about 66 microseconds (14 symbols in a 1 millisecond sub-frame), the time separation of consecutive cyclic shifts is about 5.5 microseconds.
Accordingly, the present invention has been designed to solve the above-mentioned problems occurring in the prior art, and an aspect of the present invention is to provide an apparatus and method for allocating frequency resources for the transmission of control signals and data signals from user equipments to their serving Node B.
Additionally, an aspect of the present invention is to determine the partitioning of RBs allocated to PUCCH transmissions among the RBs used for CQI transmissions, periodic ACK/NAK transmissions due to persistent PDSCH scheduling, and dynamic ACK/NAK transmissions due to dynamic PDSCH scheduling.
Additionally, an aspect of the present invention is to maximize the bandwidth utilization for PUSCH transmissions while accommodating the PUCCH transmissions.
Additionally, an aspect of the present invention is to incorporate persistent PUSCH transmissions while avoiding bandwidth fragmentation.
Additionally, an aspect of the present invention is to facilitate the achievement of the reception reliability requirements, particularly for control signals.
Additionally, an aspect of the present invention is to inform the UEs of the first RB that is available for dynamic ACK/NAK transmissions.
In accordance with an aspect the present invention, a method is provided for determining a resource for an acknowledgement signal by a user equipment (UE) in a wireless communication system. The method includes receiving an index associated with a plurality of resource blocks (RBs) for transmission of an uplink control signal in an operating bandwidth; and determining an RB for transmission of the acknowledgement signal, based on the index.
In accordance with another aspect the present invention, a user equipment (UE) is provided for use in a wireless communication system. The UE includes a transceiver configured to transmit and receive a signal over a network; and a controller configured to control receiving an index associated with a plurality of resource blocks (RBs) for transmission of an uplink control signal in an operating bandwidth, and to determine an RB for transmission of an acknowledgement signal, based on the index.
In accordance with another aspect the present invention, a method is provided for determining a resource for an acknowledgement signal by a base station in a wireless communication system. The method includes transmitting an index associated with a plurality of resource blocks (RBs) for transmission of an uplink control signal in an operating bandwidth; and receiving the acknowledgement signal on an RB determined based on the index.
In accordance with another aspect the present invention, a base station is provided for use in a wireless communication system. The base station includes a transceiver configured to transmit and receive a signal over a network; and a controller configured to control transmitting an index associated with a plurality of resource blocks (RBs) for transmission of an uplink control signal in an operating bandwidth, and receiving the acknowledgement signal on an RB determined based on the index.
As each UE with dynamic ACK/NAK transmission is assumed to know the multiplexing capacity in one RB (this parameter can be broadcasted by the serving Node B) and its relative position with respect to ACK/NAK transmissions from other UEs (either through explicit signaling by the serving Node B or implicitly, such as for example through the index of the PDCCH used for the scheduling assignment), it can know which RB and which resource within the RB (such as which cyclic shift of a CAZAC-based sequence) to use. For example, if the ACK/NAK multiplexing capacity is 18 and the relative order of a UE for ACK/NAK transmission is 20, that UE uses for its ACK/NAK transmission the second resource in the second RB used for dynamic ACK/NAK transmissions. In general, if the ACK/NAK multiplexing capacity in an RB is M and the relative order of a UE with dynamic ACK/NAK transmission is P, the UE may use the resource: mod(P, M),
within the RB number of Q=ceil(P/M),
where mod(x, y) is x minus times y) where n equals to floor(x divided by y). The "floor" operation rounds a number to its immediately smaller integer while the "ceil" operation rounds a number to its immediately larger integer.
