Description

1 TITLE METHODS OF UPLINK CHANNELIZATION IN LTE Related Application [0001] This application is divided from and claims the benefit of the filing date and priority of Australian application no. 2009224151, the content of which is incorporated herein by reference in its entirety. Field of the Invention [0002] The present invention relates to a method and an apparatus for physical uplink transmission for 3GPP long term evolution (LTE), and more specifically, to a method and an apparatus generally adept at remapping physical uplink control channels for both of a resource block containing acknowledgement and non-acknowledgement (ACK/NAK) channel and a mixed resource block containing the ACK/NAK channels and channel quality indication (CQI) channels. Background Art [0003] Orthogonal Frequency Division Multiplexing (OFDM) is a popular wireless communication technology for multiplexing data in the frequency domain. [0004] The total bandwidth in an Orthogonal frequency-division multiplexing (OFDM) system is divided into narrowband frequency units called subcarriers. The number of subcarriers is equal to the FFT/IFFT size N used in the system. Generally, the number of subcarriers used for data transmission is less than N because some of the subcarriers at the edge of the frequency spectrum are reserved as guard subcarriers, and generally no information is transmitted on these guard subcarriers. [0005] The Third Generation Partnership Project Long Term evolution (3GPP LTE) is a project within the Third Generation Partnership Project to improve the Universal Mobile Telecommunications System mobile phone standard to cope with future requirements. In the standards of the physical uplink of 3GPP LTE (long term evolution), one type of the resources used for transmitting the uplink control channel (PUCCH) is known as a cyclic shift (CS) for each OFDM symbol. One of important aspects of the system design is resource remapping on either a symbol, slot or subframe-level. [0006] The following three references are cited as being exemplary of contemporary practice in the art: [0007] Reference [1], R1-081155, "CR to 3GPP spec 36.211 Version 8.1.0", RAN1#52, Feb 2008, Sorrento, Italy, describes the standards of the physical channels for 3GPP, and chapter 5.4.1 will 72AA i/(1- IIlt- c 13RA.77 A1I I i2/22 i 2 be cited in the following specification in order to illustrate the slot-level remapping method for the acknowledgement and non-acknowledgement (ACK/NAK) channel in the physical uplink of 3GPP LTE system. [0008] Reference [2], R1-080983, "Way-forward on Cyclic Shift Hopping Pattern for PUCCH", Panasonic, Samsung, ETRI, RAN1#52, Feb 2008, Sorrento, Italy, discloses methods for remapping either a resource block containing only ACK/NAK channel or a resource block containing both CQI and ACK/NAK channels. [0009] Reference [3], R1-073564, "Selection of Orthogonal Cover and Cyclic Shift for High Speed UL ACK Channels", Samsung, RAN1#50, August 2007, Athens, Greece, teaches a scenario for data transmission for high speed uplink ACL/NAK channel by using a subset of the combination of the cyclic shift and the orthogonal cover. [0010] Reference [4], R1-080707, "Cell Specific CS Hopping and Slot Based CS/OC Remapping on PUCCH", Texas Instruments, February 11 - 15, 2008, Sorrento, Italy, teaches cyclic shift (CS) hopping and slot based cyclic shift/orthogonal cover (CS/OC) remapping for PUCCH format 0 and 1, i.e. in the context of uplink ACK/NAK transmissions in correspondence to downlink packets. [0011] The methods of the slot-level resource remapping recently proposed, for example as disclosed in references [2] and [3], have been included in the 3GPP standards as shown in reference [1]. One of the shortages of transmission capacity in wireless telecommunication networks is that the contemporary remapping methods for resource blocks containing control channels are designed exclusively for either ACK/NAK resource blocks with the extended cyclic prefix or for normal cyclic prefix cases where a mixed resource block containing both of the ACK/NAK and CQI channels, but contemporary remapping methods are not applicable for both. This shortage in transmission capacity prevents the contemporary techniques from being readily adapted to a complex 3GPP LTE physical uplink where ACK/NAK resource blocks may be applied by the extended cyclic prefix, adapted to a complex 3GPP LTE physical uplink where mixed resource blocks (where the ACK/NAK and CQI channels coexist) may be applied by the normal cyclic prefix, and adapted to a complex 3GPP LTE physical uplink where mixed resource blocks (where the ACK/NAK and CQI channels coexist) may be applied by the extended cyclic prefix. 72AA i/(1- IIl1t- c DRA.77 A1I Ii2/1/ i 3 SUMMARY OF THE INVENTION [0012] According to a first aspect of the present invention, there is provided a method for receiving control information, the method comprising: receiving the control information via a physical uplink control channel (PUCCH), a resource of the PUCCH being identified by a resource index; identifying the control information; and transmitting data based on the identified control information, wherein if n, mod 2=1, where n, is an index of a slot in which the control information is identified, the resource index of the PUCCH is established by h N' *() N n'(ns)=-J+h mod c PUCCH PUCCH < PUCCH -shift if shift where: (n'(ns -1)+d)mod(cN'/A CCH ,and d = { d for normal cyclic prefix d 2 for extended cyclic prefix f(1) N where PUCCH is an intermediate parameter for resource mapping, cs is a number of N" cyclic shifts used for the PUCCHs in resource blocks, Ns is a number of subcarriers in one AUCCH resource block, shift is set by one or more higher layers, and {3 for the normal cyclic prefix C = 2 for the extended cyclic prefix [0013] According to a second aspect of the present invention, there is provided an apparatus for receiving control information, the apparatus comprising: a transceiver for transmitting and receiving a signal; and a controller for receiving the control information via a physical uplink control channel (PUCCH), a resource of the PUCCH being identified by a resource index, for identifying the control information, and for transmitting data based on the identified control information, wherein if n, mod 2=1, where ns is an index of a slot in which the control information is identified, the resource index of the PUCCH is established by - = h] N ' N*i) < N. n = + (h mod) APUCCH PCCH APUCCH shift i shift where: 4 h = (n'(n, -1)+ d)mod(cN'/ AhCH) ,and d = { d 1 for normal cyclic prefix d 2 for extended cyclic prefix f(l) N where PUCCH is an intermediate parameter for resource mapping, cs is a number of N"RB cyclic shifts used for the PUCCHs in resource blocks, se is a number of subcarriers in one AUCCH resource block, shift is set by one or more higher layers, and {3 for the normal cyclic prefix C = 2 for the extended cyclic prefix According to a third aspect of the present invention, there is provided a method for transmitting physical uplink channel information, the method comprising the steps of: identifying a cyclic shift and an orthogonal cover for one or more physical uplink control channels; applying the cyclic shift and the orthogonal cover to physical uplink control channel information; mapping the physical uplink control channel information into one of a plurality of resource blocks of a first one of a plurality of slots of a subframe of the physical uplink control channels and one of a plurality of resources blocks of a second one of the plurality of slots of the subframe of the physical uplink control channels: and transmitting the physical uplink control channel information to which the identified cyclic shift and orthogonal cover are applied and which are mapped to the resource blocks;, wherein when n, mod 2=1, where n, is an index of the slots within the subframe, resource indices of physical uplink control channels within the second slot of the subframe are established by n h'(n) = hi +(hmode).

BRIEF DESCRIPTION OF THE DRAWINGS [0020] A more complete appreciation of the invention, and many of the attendant advantages thereof, will be readily apparent as the same becomes better understood by reference to the following detailed description when considered in conjunction with the accompanying drawings in which like reference symbols indicate the same or similar components, wherein: [0021] Figure 1 is a block diagram of a simplified example of data transmission and reception using Orthogonal Frequency Division Multiplexing (OFDM); [0022] Figure 2 is a block diagram of a simplified example of data transmission, data reception and signal processing stages using Orthogonal Frequency Division Multiplexing (OFDM); [0023] Figure 3 is an illustration showing an example of multiplexing six units of user equipment into one resource block containing channel quality indication signals within one slot; [0024] Figure 4 is a block diagram illustrating the scenario for the transmission of physical uplink acknowledgement and non-acknowledgement channels and reference signals for acknowledgement and non-acknowledgement demodulation; 10 [0025] Figure 5 is a flow chart illustrating a transmitting method of physical uplink channel signals in accordance with the embodiments of the present invention. DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION [0026] A simplified example of data transmission/reception using Orthogonal Frequency Division Multiplexing (OFDM) is shown in Figure 1. [0027] At the transmitter, the input data to be transmitted is modulated by a quadrature amplitude modulation (QAM) modulator 111. The QAM modulation symbols are serial-to-parallel converted by a serial-to-parallel convertor 113 and input to an inverse fast Fourier transform (IFFT) unit 115. At the output of IFFT unit 115, N time-domain samples are obtained. Here N refers to the sampling number of IFFT/FFT used by the OFDM system. The signal transmitted from IFFT unit 115 is parallel-to-serial converted by a parallel-to-serial convertor 117 and a cyclic prefix (CP) 119 is added to the signal sequence. The resulting sequence of samples is referred to as the OFDM symbol. Serial to parallel convertor 113 uses shift registers to convert data from serial form to parallel form. Data is loaded into the shift registers in a serial load mode, and is then shifted parallel in a shift mode with a clock signal. [0028] At the receiver, the cyclic prefix is firstly removed at cyclic prefix remover 121 and the signal is serial-to-parallel converted by serial-to-parallel convertor 123 before feeding the converted parallel signal into fast Fourier transform (FFT) transformer 125. Output of FFT transformer 125 is parallel-to-serial converted by parallel-to-serial convertor 128 and the resulting symbols are input to QAM demodulator 129. Parallel-to-serial convertor 128 uses shift registers to convert data from parallel form to serial form. Data is loaded into the shift registers in a parallel load mode, and is then shifted serially in a shift mode with a clock signal. [0029] The total bandwidth in an OFDM system is divided into narrowband frequency units called subcarriers. The number of subcarriers is equal to the FFT/IFFT size N. In general, the number of subcarriers used for data is less than N because some of the subcarriers at the edge of the frequency spectrum are reserved as guard subcarriers, and no information is transmitted on guard subcarriers. [0030] Figure 2 is a block diagram of a simplified example of data transmission, data reception and signal processing stages using Orthogonal Frequency Division Multiplexing (OFDM). As shown in Figure 2, serial-to-parallel convertor 113 and IFFT unit 115 map the converted parallel signal into one resource block and transform a frequency domain representation of the converted parallel signal to a time domain representation. The OFDM symbols output from cyclic prefix (CP) 119 are further processed by signal processing unitTx 120 before being transmitted by the transmitting antennas. Similarly, the processed OFDM symbols transmitted from the transmitter 72AA i/(1- IIl1t- c DRA.77 A1I Ii2/1/ i 11 are firstly processed by signal processing unitRx 122 before received by the receiving antennas. Signal processing unitTx 120 and signal processing unitRx 122 perform signal processing respectively for the transmitter and the receiver in accordance with certain signal processing schemes. [0031] In the uplink of 3GPP LTE standards, one type of the resource used in the uplink control channel (PUCCH) is known as a cyclic shift (CS) for each OFDM symbol. PUCCHs are defined as channels carrying control signals in the uplink, and PUCCHs may carry control information, e.g., channel quality indication (CQI), ACK/NACK, hybrid automatic repeat requests (HARQ) and uplink scheduling requests. [0032] The physical uplink control channel, PUCCH, carries uplink control information. All PUCCH formats use a cyclic shift (CS) of a sequence in each OFDM symbol. Figure 3 is an illustration showing an example of multiplexing six user equipments (UEs) into one resource block containing channel quality indication (CQI) signals within one slot. In Figure 3, the PUCCH occupies twelve subcarriers in the resource block and twelve cyclic shift resources (co through cn) exist in the resource block. The CQI signals include both of CQI data signals (e.g., CQI data signal 201) occupying several symbol elements (e.g., so) within the OFDM symbols and CQI reference signals (e.g., CQI reference signal 202) occupying several symbol elements (e.g., si). Six UEs (i.e., UE 1 through UE 6) are multiplexed in the resource block. Here, only six out of twelve cyclic shifts are actually used. [0033] Figure 4, cited from reference [3], shows the working assumption on the transmission block of uplink ACK/NAK channels and reference signals. Here, the position of the reference signal long block is not determined, therefore, Figure 4 is only for illustrative purposes. Serial-to parallel convertor 113 and IFFT unit 115 transform a frequency domain representation of the ACK/NAK signals and the uplink reference signals to a time domain representation, and map the ACK/NAK signals and the uplink reference signals into the transmission block. ACK/NAK signals and the uplink reference signals (UL RS) for ACK/NAK demodulation are multiplexed on code channels 301 constructed by both a cyclic shift of a base sequence (e.g., Zadoff-Chu sequence) and an orthogonal cover. ACK/NAK signals and the uplink reference signals are multiplexed on code channels 301 constructed by both of a Zadoff-Chu sequence ZC(u,r) and an orthogonal cover. For ACK/NAK channels, a Zadoff-Chu sequence ZC(u,r) with a particular cyclic shiftr, ZC(u,r) is placed in sub-carriers and an orthogonal cover is applied to time domain long block (LB). The IFFTs transform a frequency domain representation of the input sequence to a time domain representation. The orthogonal cover may be used for both of UL RS and for 12 PUCCH data, the actual code of the orthogonal cover used only for UL RS is different from {wo, w 1 , w 2 , w} which is used only for PUCCH data. [0034] Here, Figure 3 shows an example of a mapping method exclusively adapted to resource blocks only containing CQI channels, and Figure 4 shows an example of a mapping method for ACK/NAK channels. [0035] One important aspect of system design is resource remapping on a symbol, slot or subframe-level. Section 5.4.1 of reference [1], which includes the slot-level remapping of the ACK/NAK channel in the uplink control PUCCH channel of LTE, is cited below for ease of exposition. "5.4 Physical uplink control channel V(2) ( ... The physical resources used for PUCCH depends on two parameters, nRB and Ncs , given by higher layers. The variable RB > denotes the bandwidth in terms of resource blocks that are reserved exclusively for PUCCH formats 2/2a/2b transmission in each slot. The variable denotes the number of cyclic shift used for PUCCH formats 1/la/lb in a resource block used for a mix of formats 1/la/lb and 2/2a/2b. The value of N is an integer multiple of A CH within the PuCCH range of {0, 1, ... , 8}, where Asft is defined in section 5.4.1. No mixed resource block is present if Ncs =0 . At most one resource block in each slot supports a mix of formats 1/la/lb and 2/2a/2b. Resources used for transmission of PUCCH format 1/la/lb and 2/2a/2b are represented by the n(CC <NA (N , I+ (N (A -N'(') -2) non-negative indices nPUCCH and , respectively. 5.4.1 PUCCH formats 1, la and lb [0036] For PUCCH format 1, information is carried by the presence/absence of transmission of PUCCH from the UE. In the remainder of this section, d(0)=1 shall be assumed for PUCCH format 1. [0037] For PUCCH formats la and 1b, one or two explicit bits are transmitted, respectively. The block of bits b(O),...,b(AMbit -1) shall be modulated as described in section 7.1, resulting in a complex-valued symbol d(O) . The modulation schemes for the different PUCCH formats are given by Table 5.4-1.

[0042] In the present invention, novel slot-level remapping methods are proposed to provide a better intra-cell randomization, especially for ACK/NAK resource blocks with extended cyclic prefix, and for normal cyclic prefix cases with mixed resource block where the ACK/NAK and CQI coexist in a single resource block.

The invention is also capable of other and different embodiments, and its several details can be modified in various obvious respects, all without departing from the spirit and scope of the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

In section 5.4.1 of 3GPP standards TS 36.211 V8.4.0, it is stated that: "The resource indices within the two resource blocks in the two slots of a subframe to which the PUCCH is mapped are given by 1 (1) f PUCCH , niCCHCCH <cN shPfC n(n 5 ) n (PUCCH - c -N (A) / CH )mod(c.

[0053] Comparing 3GPP standards version TS 36.211 V8.4.0 (2008-09) and 3GPP standards version TS 36.211 V8.4.0 (2008-05), the latest 3GPP standards version TS 36.211 V8.4.0 (2008 09) implanted the equations for the resource indices for both of the extended CP case and mixed RB case, and introduces a new parameter "d" for the mapping of the resource indices of the physical uplink control channels within one of two slots of a subframe by implanting the present invention, and the resource indices are given by n'(n 5 )= [c(n'(n, -1) + 1)] mod(cN?:/A CH + 1 PZCCH c- N/ h s /h/c]+(hmodc)N/A CH otherwise frns mod2= whereth= (n'(n, - 1)±+d) mod~cl IAPUCCH for , where (cN " with d = 2 for normal CP and d = 0 for extended CP. By introducing the above stated equations and the parameter "d" for the mapping of the resource indices, the present invention achieves a better randomization and a better performance of the mapping of the resource blocks within the communication system.
