Abstract

Techniques for sending control information on a variable control channel are described. Different structures for mapping control information to control channel resources may be used depending on various factors such as operating configuration, the available resources for the control channel, the type (s) of control information being sent, the amount of control information being sent for each type, whether or not data is being sent, etc. In one design, at least one type of control information being sent may be determined and may comprise channel quality indicator (CQI) information, acknowledgement (ACK) information, and/or other types of control information. A structure of the control channel may be determined based on operating configuration (e. g., system configuration such as asymmetry of downlink and uplink allocations) and/or other factors. The at least one type of control information may be mapped to the resources for the control channel based on the structure.

Description

200818801 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates generally to communications, and more particularly to techniques for transmitting control information in a wireless communication system. [Prior Art] Wireless communication systems are widely used to provide various communication services such as voice, video, packet data, message 'broadcast, and the like. Such wireless systems can be multiple proximity systems that can support multiple users by sharing available system resources. Examples of such multiple proximity systems include · a code division multiple proximity (CDMA) system, a time division multiple proximity (11), a system, a frequency division multiple proximity (FDMA) system, a quadrature FDMA (〇FDMA) system, And single carrier FDMA (SC-FDMA) system. In a wireless communication system, a Node B (or base station) can transmit data to a User Equipment (UE) on the downlink and/or receive data from the UE on the uplink. The downlink (or forward link) refers to the communication link from the node ^ UE, and the uplink (or reverse link) refers to the communication link from ue to node B. The control information (such as system resource assignment) can be developed to the UE at the time of the node. Similarly, the UE may send control information to node b to support the transmission of data on the link and/or for other destinations. It is necessary to send, data and control information as efficiently as possible to improve system performance. SUMMARY OF THE INVENTION This document describes techniques for shipping control information on a tunable batch. The variable control channel can be used to support one or more types of control information. The H-day lacks the use of different knots according to various factors. Doc 200818801 Structure (4): The information is mapped to resources, such as the operational configuration, the available lean source of the control channel, the type of control being sent, the amount of control information being sent for each type, whether the data is being sent, and so on. Therefore, the structure of the control channel can be varied by different factors. In the design, the control information of at least one type of information being transmitted can be determined and the at least one type of control information being transmitted can include channel quality only. Instructed by the Secretary) Information, only convinced (woven) f, CQi and ack information

And/or other types of control information. The structure of the control channel can be determined based on the operational configuration and/or other factors. The operational configuration can be determined based on system group capabilities, UE configuration, and the like. The system configuration indicates the number of subframes allocated for the downlink and the number of subframes allocated for the uplink. The UE configuration may indicate that the assigned sub-frames are applicable to the UE's downlink f link and uplink integrity. The control channel structure can be determined based on the asymmetry of the downlink and uplink assignments. In a design, the (four) channel can include (1) - from the time of not sending - control ::! The amount of resources (9) - from the data section when the data is sent, and the source of the source. The at least one type of control information can be mapped to the resources of the 5H control channel according to the structure. Each type of control education can be mapped to a corresponding portion of the control channel resources in accordance with the structure. Various aspects and features of the present invention are described in further detail below. [Embodiment] FIG. 1 shows a wireless communication system 100 having a plurality of sections 110 and a plurality of UEs 12G. A Node B is typically a fixed base station and can also be referred to as an evolved Node B (eNode B), a base station, an access point, and the like. Each of the 123116.doc 200818801 提供 Β 〇 提供 provides communication coverage for a specific geographic area and supports communication for UEs located within the coverage area. Depending on the context in which the term is used, the term 'cell' can refer to a node and/or its coverage area. A system controller 130 can be coupled to a node and provide coordination and control for such nodes. The device 130 can be a single network entity or a set of network entities, such as a smashing system/system architecture evolution (SAE) gateway, a radio network controller (RNC), and the like. The UE 120 may be distributed throughout the system, and each of the UEs may be fixed or mobile. The UE may also be referred to as a mobile station, a mobile device, a terminal, an access terminal, a subscriber unit, One can wait for a cellular phone, a PDA, a wireless communication device, a handheld device, a wireless data modem, a laptop computer, etc. 1 2 B can be in the downlink Transferring data to one or more on the road and/or from any one or more receiving resource nodes B on the uplink may also send control information to the UE&/or from 1}£ receiving control' In Figure 1, f has a solid line with double arrows (for example, at node b 11 〇a and UE 12 Between b) represents data transmission on the downlink and uplink and control information transmission on the uplink. A solid line with a single arrow pointing to a UE (eg 120e) represents data transmission on the downlink and uplink. Controlling the transmission of the cipher. A solid line with a single UE (for example, ue 12 私 私 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表 代表The dotted line of the arrow represents the control information (but no data) transmission on the uplink. For the sake of simplicity, the control information transmission on the downlink is not shown in Figure 1. A given 123116.doc 200818801 is available on the downlink. The data is transmitted or transmitted on the uplink-fixed uplink key, and /, the port is transmitted on the uplink to transmit control information. Figure 2 shows the real chain 踗徨柃τ of a node b. And a glimpse of the uplink transmission. The UE may periodically be the node and may estimate the quality of the downlink link channel by rm-i..3 to be sent to the UE under the UE (4). The node β may be used. The (10) information comes to the 1st speed HT (DL) _ round Select the appropriate rate (for example, the data should be p ^ scheme) ° Node B can process the data and transmit the data to the UE when there is from the rZ and the system resources are available. The 丨 丨 枓 transmission is processed and a confirmation can be sent when the data is decoded (A ^ 政 , , , , 隹 隹 枓 枓 枓 枓 务 务 务 务 务 ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ", occupies the retransmission of the sage when receiving a glimpse and can receive the new acquaintance of the AC, the one that can be found. The UE can also send data and Ujg refers to s? When the 仃/τττ is coupled with the 仃 link resource, the data is transmitted to the node β on the uplink (UL). As shown in FIG. 2, the UE may transmit data and/or control information 'or neither at any given time interval'. The control information can also be referred to as control, open communication, and the like. The control information may include ack/nak, na, other negative σίΐ, or any combination thereof. The type and quantity of the system can depend on various factors, such as the number of streams being sent, whether multiple input multiple output arrays are used for transmission, and so on. For the sake of brevity, a large number of the following description assumes that the control information includes CQI and ACK information. The system supports hybrid automatic retransmission (harq), and hybrid automatic retransmission can also be called incremental redundancy, chasing merge, and so on. For HARQ on the downlink, the section (four) can transmit-pair-packet transmission and can send a 123116.doc 200818801 or more retransmissions until the packet is correctly decoded by the UE, or the maximum number of retransmissions have been sent. Or encounter some other termination condition. HARQ improves the reliability of data transmission. Z HARQ interlaces can be defined, where Z can be any integer value. Each HARQ interlace may include a time interval separated by Z time intervals. For example, when z e {1,...5 6}, six HARQ interlaces may be defined, and the HARQ interlace z may include time intervals n+z, n+z+6, H+Z+12, and the like. A HARQ process can refer to all transmissions and retransmissions (if any) of a packet. A HARQ process can begin when resources are available and can be terminated after the first transmission or after one or more subsequent retransmissions. A HARQ process can have a variable duration that can depend on the decoding results at the receiver. Each HARQ process can be sent on one HARQ interlace. In one design, up to Z HARQ processes can be transmitted on the Z HARQ interlaces. In another design, multiple HARQ processes may be sent on different resources (e.g., on different sets of subcarriers or from different antennas) in the same HARQ interlace. The transmission techniques described herein can be used for both uplink and downlink transmissions. These techniques can also be used in a variety of wireless communication systems, such as CDMA, TDMA, FDMA, OFDMA, and SC-FDMA systems. The term "system π and" networks are often used generically. A CDMA system may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (W-CDMA) and low chip rate ( LCR). cdma2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA system can implement a wireless technology such as Global System for Mobile Communications (GSM) 123116.doc -10- 200818801. An OFDMA system can execute one. Radio technologies such as Evolved UTRA (E-UTRA), IEEE 802.11, IEEE 802.16, IEEE 802.20, Flash-OFDM8, etc. These different radio technologies and standards are well known in the industry. UTRA, E-UTRA and GSM is part of the Universal Mobile Telecommunications System (UMTS), an upcoming UMTS release that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS and LTE are described in a The literature provided by the organization of the Three Generations Partnership Program " (3GPP). Cdma2000 is described in the literature provided by an organization called "3rd Generation Partnership Project 2" (3GPP2). For clarity, certain aspects of the techniques are set forth below for uplink transmissions in LTE, and 3GPP terminology is used in the following extensive description. LTE utilizes orthogonal frequency division multiplexing (OFDM) on the downlink and single carrier frequency division multiplexing (SC-FDM) on the uplink. OFDM and SOFDM divide the system bandwidth into multiple (N) orthogonal subcarriers (which are also commonly referred to as tones, bins, etc.). Each subcarrier can be modulated by data. In general, modulation symbols are transmitted in the frequency domain by OFDM and in the time domain by SC-FDM. For LTE, the spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (N) can depend on the system bandwidth. In a design, when a system bandwidth is 5 MHz, N=5 12, when a system bandwidth is 10 MHz, 1024, and when a system bandwidth is 20 MHz, in general, N can be any Value. Figure 3 shows a design of a structure 300 that can be used to transmit data and control information on the uplink. The transmission timeline can be divided into sub-frames. A sub-frame can have a fixed duration, such as one millisecond (ms) or one set of 1231I6.doc 11 200818801 state duration. A sub-frame can be divided into two time slots, and each time slot includes L symbol periods, where [may be any integer value, such as or 7. Each symbol period can be used for data, control information, pilot signals, or any combination thereof. In the design shown in FIG. 3, a total of the N subcarriers can be divided into a data section and a control section. The control section can be formed at one of the edges of the system bandwidth, as shown in FIG. The control section can have a configurable size' which can be selected based on the amount of control information being sent by the UE on the uplink. The data section may include all subcarriers not included in the control section. The design of Figure 3 produces a lean section comprising consecutive subcarriers, thereby allowing all of the consecutive subcarriers in the data section to be assigned to a single 17 £. A UE may be assigned a control segment consisting of M consecutive subcarriers, where Μ may be a fixed value or a configurable value. A control segment may also be referred to as a physical uplink control channel (PUCCH). In one design, a control segment may include an integer multiple of 12 subcarriers. The UE may also be assigned a data segment consisting of Q consecutive subcarriers, where Q may be a fixed value or a configurable value. A data segment may also be referred to as a physical uplink shared channel (PUSCH). In a design, a data segment can include an integer multiple of one of the 12 subcarriers. It is also possible to assign a data segment or a control segment to the UE in a given subframe. The UE may be required to use SC-FDM for transmission on consecutive subcarriers, which is referred to as Local Frequency Multiplexing (LFDM). A lower peak-to-average ratio (pAR) can be produced on the continuous subcarrier uploading wheel. The ratio of the peak power of a waveform to the average power of the waveform. A low PAR is desirable because it allows 123116.doc -12-200818801 to operate a power amplifier (PA) with an average output power closer to the peak output power. This in turn increases the flux and/or the margin of the switch. It can be assigned to the U E - a control segment located near one edge of the system bandwidth. It can also be assigned to the UE when there is no bait to send - located in the section of the data section. The subcarrier of the control segment may not be the wave of the data segment. If no data is to be sent on the uplink, then ue = control information for the segment command. If there is data to be sent on the uplink = UE can, send the data and control information in the data segment. Such dynamic transmission of control information enables the UE to increase the pAR in the continuous carrier uploading round regardless of the transmission of data.疋 .:=No data to be transmitted on the uplink - transmission in the subframe. The UE may be assigned a control segment, and the control segment may be mapped to a different set of subcarriers in the two slots of the subframe. ^ can be two: The sub-carrier remaining subcarriers assigned to the control segment in the number period can be used by other UEs for uplink key transmission. Figure 4B shows that when there is a data |, the message is transmitted and the data is to be sent on the cut link and the control frame = one is assigned to a data segment, the data segment can be mapped to a different one in the -one message slot. Subcarrier set. The UE can be in each system of information. The remaining (four) carriers transmit data and control signals from the uplink and transmission. A frequency jump between each time slot is displayed. Frequency hopping can also be done at other times. Frequency hopping provides frequency diversity: ;== randomizes between sub-frames. ' Have. Road detection effect and interference 123ll6.doc -13· 200818801 The system can support - frequency division duplex (FDD) mode and / or - time division duplex (lion) mode. In the FDD mode, individual channels can be used for the downlink and uplink links' and the downlink transmission and uplink transmission can be simultaneously transmitted on the basin and other channels. In the employment mode, the total (four) track can be used for both 路 = way and uplink. The downlink transmission can be tested in some time periods and the uplink transmission can be sent in other time periods. Figure 5 shows the time structure that can be used in the TDD mode. This line can be divided into sub-frame units. Each frame can be spanned by a predetermined duration (for example, 1 call, and can be divided into a predetermined number of subframes. In each frame, 1 subframe can be allocated for the downlink, and can be Uplink: with nul sub-frames. Ndl& can be any suitable value and can be configured based on downlink and uplink traffic loads and/or other considerations. Downlink and Uplink There may be symmetric or asymmetric assignments depending on the system configuration. For symmetric downlink and uplink assignments, the number of downlink subframes is equal to the number of uplink subframes, or N == NUL. A downlink sub-frame can be associated with a corresponding uplink sub-frame. For example, ' _f material transmission can be sent in the downlink sub-chassis type' and the control information of the data transmission can be in the corresponding uplink. In the link subframe η, 'where ne{1,..., Ndl} is transmitted. For asymmetric downlink and uplink allocation, the number of downlink subframes and the number of uplink subframes are not Match, or Nm>NuL. Therefore, under ^ There is no possibility of a pair-to-map between the link and the uplink subframe. A non-proportional allocation can achieve a more flexible system resource matching with the load conditions. 1231I6.doc -14 - 200818801

But the system operation can be complicated. D Figure 6 shows a case-by-case transmission in the case of asymmetric downlink and uplink assignments. For the real money, M downlink sub-frames! The Μ can be associated with a single uplink key subframe, where 乂 can be any integer value. A UE may be assigned resources in downlink subframe 1 to Μ and associated uplink _ subframes. Each packet may be sent to the UEc UE in the downlink: subframes of the HARQ process. The UE may decode each packet and determine the ACK information of the packet. The ACK information may also be referred to as ACK feedback and may include ACK or NAK. The UE may send ACK information of all the packets in the uplink frame. In Figure 6, acki is the ACK information of the packet sent on the HARQ over H1, and ackm is the ACK information of the packet sent on the HARQ process HM, where the ACK can be any available HARQ process. This ACK information can be used to control the transmission of new packets and retransmission of erroneously decoded packets. In a bad case, a variable control channel can be used to support both symmetric and asymmetric _ downlink links and uplink assignments. The control channel can be assigned a different amount of resources, for example, depending on whether or not the bedding is being shipped. This control channel can be used to send different types of control information and/or different amounts of control information to the stem/tongue. For the sake of clarity, the specific design of the variable channel will be explained below. In such designs, the control channel can be assigned a four source unit in a control segment when no data is sent and the control channel can be assigned a variable number of resource units in a block segment when transmitting the data. - Resource units can correspond to a source or a logical resource. Entity resources may be used for transmission of resources and may be defined by subcarriers and chronographs. Logical resources can be used to simplify the allocation and can be mapped to physical resources based on a mapping, a transformation, and the like. The source unit can have any size and can be used to send one or more control A bits. In the following design, the control channel can be used to transmit only CQJ information, or only ACK information for up to three HARQ processes, or both CQI and ACK information, or no control information. Figure 7-8 shows the design of the control channel structure for transmitting ACK information for up to three HARQ processes on the control segment when CQI and data are not transmitted. In Figure 7A, the four resource elements of the control segment can be represented by a 2χ2 matrix. The first and second columns of the matrix correspond to two virtual frequency resources (VFR) Si and S2, respectively. – VFR may be a set of subcarriers that may be mapped to a set of subcarriers or may correspond to some other logical or physical resource. The matrix and the younger brother row may correspond to two time slots τ 1 and T2 of one subframe, respectively. The four blocks of the 2x2 matrix may correspond to four resource elements of the control channel. In the following description, H1, m and yang can be any of the three different HARQ processes. In one design, the ACK information (ACK1) of a HARQ process H1 can be sent on all four resource elements of the control segment shown by a structure 712. For example, the ACK information can be repeated four times and sent on all four resource elements to improve reliability. In one design, the ACK information for the two HARQ processes H1 and H2 can be transmitted on the four resource elements of the control segment shown by a structure 714. In this case, the ACK information (ACK1) of the HARQ process H1 can be transmitted on two resource elements occupying the VFR S1 in the time slots T1 and D2. The HARq procedure H22 123116.doc -16- 200818801 ACK information (ACK2) can be transmitted on two resource elements occupying VFR S2 in time slots T1 and T2. In one design, the ACK information for the three HARQ processes HI, H2, and H3 can be transmitted on the four resource elements of the control segment shown by a structure 716. In this design, the ACK information (ACK1) of the HARQ process H1 can be transmitted on a resource unit occupying VFR S1 in the time slot T1. The ACK information (ACK2) of the HARQ process H2 can be transmitted on a resource element occupying VFR S2 in time slot T1. The ACK information (ACK3) of the HARQ process H3 can be transmitted on one resource unit occupying VFR S 1 in the time slot T2. The remaining resource units can be shared by the three HARQ processes in a time division multiplexing (TDM) manner. For example, the resource unit can be used for the ACK information of the HARQ process H1 in a subframe, and then used for the ACK information of the HARQ process H2 in the next subframe, and then used for the HARQ in the next subframe. Process H3 ACK information, and so on. In another design, ACK information for all three HARQ processes can be encoded with one (4, 3) block code and sent on all four resource units. The ACK information of the three HARQ processes can also be sent in other ways. Figure 7B shows the design of a control channel structure for transmitting CQI and ACK information for up to three HARQ processes on the control segment when no data is transmitted. In one design, when no ACK information is sent, the CQI information can be sent on all four resource elements of the control segment shown by a structure 720. In one design, the CQI and ACK information for a HARQ process H1 can be sent on the four resource elements of the control segment shown by a structure 722. In this design, the CQI information can be sent on two resource units occupying 123116.doc -17-200818801 of VFR S 1 in time slots T1 and T2. The ACK information of the HARQ process HI can be transmitted on two resource elements occupying VFR S2 in time slots T1 and T2. In one design, the CQI and ACK information for the two HARQ processes H1 and H2 may be transmitted on the four resource elements of the control segment shown by a structure 724. In this design, the CQI information can be transmitted on two resource elements occupying the slots T1 and T2: VFR S1. The ACK information of the HARQ process H1; can be transmitted on one resource unit occupying the VFR S2 in the time slot T1. The ACK information of the HARQ process H2 can be sent on a ® #1 resource unit occupying VFR S2 in time slot T2. In one design, the CQI and ACK information for the three HARQ processes HI, H2, and H3 may be sent on the four resource elements of the control segment shown by a structure 726. In this design, the CQI information can be transmitted on a resource unit occupying VFR S1 in time slot T1. The ACK information of the HARQ process H1 can be transmitted on a resource element occupying VFR S2 in time slot T1. The ACK information of HARQ process H2 can be transmitted on a resource unit that occupies VFR S 1 in time slot T2. The ACK information of the HARQ process H3 can be transmitted on one resource unit occupying VFR S2 in time slot T2. Figure 7C shows the design of a control channel structure for transmitting ACK information for up to three HARQ processes on the data segment when transmitting data but without CQI. • The data segment can include 2K resource elements and can be represented by a Kx2 matrix, where any value can be tied. The queue of the matrix may correspond to the one of the VFRs S1' to SK1, where sr may be the lowest index and SK' may be the highest index of the K VFRs of the data segment. The first and second rows of the matrix may correspond to two time slots T1 and T2 of a dummy subframe, respectively. The 2K blocks of the Kx2 matrix can be applied to 2K resource units for 123I16.doc -18 - 200818801. The source unit of the data segment may have the same or a different size as the source unit of the control segment. As shown in Figure %, a different number of resource bills can be taken from the f-segment and used to send a different amount of control information. The remaining resource units in the data segment can be used to send data. In one design, a HARQ process H12ACK message may be sent on two resource elements of a data segment as shown by a structure 732. The two resource elements can occupy VFR S1 in time slots T1 and T2. The remaining 2K_2 resource units are available for data. In a juice setting, two HARQ processes 孓1 and 孓2孓ACK information can be sent on four resource elements of the data segment shown by a structure 734. In this design, the ACK information of the HARQ process 可 1 can be transmitted on two resource elements occupying the VFR S1' in the slots τι and Τ2. The HARQ process H22ACK traffic can be sent on two resource elements occupying VFR S2 in time slots T1 and T2. The remaining 2K-4 resource units are available for data. In one design, the ACK information for the three HARQ processes HI, H2, and H3 can be sent on six resource elements of the data segment shown by a structure 736. The ACK information of the HARQ process 于1 in this scheme can be transmitted on two resource elements occupying VFR S 中 in slots τ 1 and T2. The ACK information of the HARQ process Η 2 can be transmitted on two resource elements occupying VFR S2 in slots Τ1 and Τ2. The ACK information of the HARQ process Η3 can be transmitted on two resource elements occupying the VFR S3 of the data segment in the slots τι and Τ2. The remaining 2Κ-6 resource units are available for data. Figure 7D shows the design of a control channel structure for transmitting CQI and ACK information for up to three HARQ processes on the data segment as the data is transmitted. In a design, the CQI information can be sent on two resource elements of a data segment as shown by a structure 740. The two resource elements can occupy VFR S r in time slots T1 and T2. The remaining 2K-2 resource units are available for data. In one design, the CQI and ACK information for a HARQ process H1 can be sent on four resource elements of the data segment shown by a structure 742. In this design, the CQI information can be transmitted on two resource elements occupying VFR S11 in time slots T1 and T2. The ACK information of the HARQ process H1 can be transmitted on two resource elements occupying the VFR S21 in the time slots T1 and T2. The remaining 2K-4 resource units are available for data. In one design, the CQI and ACK information for the two HARQ processes H1 and H2 can be transmitted on six resource elements of the data segment shown by a structure 744. In this design, the CQI information can be transmitted on two resource elements occupying VFR Sr in time slots T1 and T2. The ACK information of the HARQ process H1 can be transmitted on two resource elements occupying VFR S2' in time slots T1 and T2. The ACK information of the HARQ process H2 can be transmitted on two resource elements occupying VFR S3' in time slots T1 and T2. The remaining 2K-6 resource units are available for the tribute. In one design, the CQI and ACK information for the three HARQ processes HI, H2, and H3 can be sent on eight resource elements of the data segment shown by a structure 746. In this design, the CQI information can be transmitted on two resource elements occupying VFR S1' of time slots T1 and T2. The ACK information of the HARQ process H1 can be transmitted on two resource elements occupying VFR S2' in time slots T1 and T2. The ACK information of the HARQ process H2 can be transmitted on two resource elements occupying the VFR S3* in the time slots T1 and D2. The ACK information of the HARQ process H3 can be sent on the two resource elements of the time slot 1^ and the VFR S4 of the D2 in 123116.doc -20-200818801. The remaining 2K-8 resource units are available for data. Figures 7A through 7D show the specific design of the control channel structure for transmitting the cut and information in the control segment and the data segment. These designs display (10) and / ACK information to a specific mapping of resource elements available for transmission of control information. CQI and ACK information can also be mapped to available resource units in a variety of other ways. As an example, the structure 714 in FIG. 7 is not used, but the information of the HARQ process H1 can be transmitted in the following: (1) the upper left and lower right resource units in the matrix, and (u) the matrix source matrix TM matrix. The upper left and lower left resource list in the left left = the other - instance '-block code can be used for all control information being sent, and the obtained codeword can be sent on all available resource units. The information can be added in various ways, such as using time division multiplexing (TDM), frequency division multiplexing (FDM), code division multiplexing (cdm), etc., or a combination thereof. In the design shown in Figures 7-8 to 71), a combination of one of the hires and the FDM can be used for the control channel. In such designs, each VFR may correspond to a set of subcarriers. For example, the control segment may be assigned 12 subcarriers, each VFR may correspond to six subcarriers, and one resource unit may correspond to six subcarriers of [slot periods of each slot: each The CQI or ACK information of a HARQ process can be sent in the assigned resource unit, for example, as shown in FIGS. 7-8 to 7D. - TDM can also be used for this control information. In this case, all control information mapped to a given time slot can be processed (e. g., co-coded) and sent on all subcarriers of the control channel in the time slot. As an example, for the structure 726 of FIG. 7B for 123116.doc * 21 - 200818801, the CQI and ACK information of the HARQ process HI can be processed and transmitted on all subcarriers in the slot ,, and the HARQ process H2 The ACK information of H3 and H3 can be processed and transmitted on all subcarriers in time slot T2. FDM can also be used for this control information. In this case, all control information mapped to a given VFR can be processed (e. g., co-coded) and transmitted on all of the sub-carriers in the VFRs on both time slots. As an example, for the structure 726 in FIG. 7B, the CQI and ACK information of the HARQ process H2 can be processed and transmitted on the subcarriers in the VFR S1 on the two time slots T1 and T2, and the HARQ The ACK information for procedures H1 and H3 can be processed and transmitted on all subcarriers in VFR S2 on the two time slots T1 and T2. CDM can also be used for this control information. In this case, the CQI and ACK information can be spread, combined, and subsequently mapped to all resources available for transmission of control information by orthogonal codes. The control information can also be sent by changing the modulation order. For example, BPSK can be used to send a control information bit, QPSK can be used to send two information bits, 8-PSK can be used to send three information bits, 16-QAM can be used to send four information bits, etc. . The design in Figures 7A through 7D assumes that two types of control information - CQI and ACK information are being transmitted.

The amount of CQI information may be fixed (as shown in Figures 7A to 7D) or variable (for example, depending on whether ΜΙΜΟ is being used or not) The number of streams, etc.).

The design in Figures 7A through 7D assumes that the control channel includes: (1) a fixed number of information units when no data is being transmitted and (ii) a variable number of source units when transmitting data. In general, the control channel can include a fixed or variable number of resource units when not shipping poor materials and (or) a fixed or variable number of resource units when transmitting data. It can be used for this control; the number of resource units in the channel can be different from that shown in the picture. , and σ, the 5 huh available control channel may have a structure that varies by one or more of the following factors: 沆 , , , , , , , , , , , , , , , , , , , , Downlink and uplink assignments in the uplink and sub-frame counts, • UE configuration, you | ' m , available for UE downlink and uplink frame, • available The amount of control information transmitted on the control channel, such as the type of control information sent on the control channel, such as CQI and/or ACK poor, • the amount of control information HARQ is being sent for each type, U is indeed 5 Bit·= is transmitting data, which determines the size of the control channel I23116.doc -23- 200818801 • The reliability of each type of control f-desired. The control channel can support the transmission of control information for one or more types of (four) types by means of variable resources. Different structures can be used to map control information to the control source based on various factors (such as frequency above, f-element). Thus, the structure of the control channel can be due to such different factors. Figure 8 shows the design of process 800 for transmitting control information.

It can be configured according to the system (for example, the asymmetry of the downlink and uplink link assignment), the configuration (for example, the downlink and uplink subframes are applicable), and so on. A plurality of structures of the control channel can be supported, and some examples of the plurality of structures are given in Figures 7 to 7D. The m-channels in the supported structure may be selected according to the operational configuration and/or other factors, which may include: (1) when the data is not transmitted: the amount of resources, or (8) the variable from a data segment when the data is transmitted. Beiyuan straight. These control and data segments can occupy different frequency locations. At least one type of control information can be mapped to the resources of the control channel in accordance with the structure (block 816). The control channel resources may include time resources, frequency resources, code resources, etc., or any combination thereof. Each type of control information can be mapped to one of the control channel resources according to the structure. 123lI6.doc -24- 200818801 should be part.
