Description

METHOD AND SYSTEM FOR SUPPLYING CONTROL INFORMATION, TO SUPPORT ACCESS TO LINK PACKAGES DESCENDING FROM I HIGH SPEED AND HIGH SPEED ASCENDING LINK i FIELD OF THE INVENTION The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and system for supplying control information to support high-speed downlink and uplink.

BACKGROUND The third generation society project I (3GPP) issues 5 and 6 provide HSDPA and HSUPA for high-speed transmissions in the downlink and uplink, respectively. For HSDPA and HSUPA operations, a B-node dynamically allocates radio resources to a plurality of user equipment (UE) and several physical channels are provided to the UEs. There are two physical downlink channels and one physical uplink channel in HSDPA. The physical downlink channels include a high-speed shared control channel (HS-SCCH) and a high-speed physical downlink shared I channel (HS-PDSCH). The physical uplink channel includes a dedicated high-speed physical control channel (HS-PDCCH). : The HS-SCCH carries HSDPA downlink control information. The downlink HSDPA control information includes a set of channelization code, a modulation scheme, a transport block size, hybrid automatic repeated request procedure information (H-ARQ), in its version of redundancy and constellation, a new data indicator and a UE (ID) identity. A UE is assigned up to four (4) HS-SCCHs in a cell via radio resource control signaling (RRC). The UE needs to monitor all of one or more of the assigned HS-SCCHs before receiving control information for HSDPA. i The HS-PDSCH carries HSDPA downlink data packet. Based on the processing of HS-PDSCH (for example, cyclic redundancy check (CRC) and H-ARQ processing), the UE sends a positive recognition (ACK) or negative recognition (NACK) signal to the B-node via the HS-DPCCH. The HS-DPCCH also carries a channel quality indicator (CQI). There are three physical downlink I channels and two uplink physical channels in HSUPA. Physical downlink channels include an enhanced dedicated channel (E-DCH), an absolute grant channel (E-AGCH), a relative grant channel E-DCH (E-RCGH) and an E-DCH indicator channel H-ARQ (E-HICH). The uplink physical channels include a dedicated physical data channel E-DCH (E-DPDCH) and a dedicated physical control channel E-DCH (E-DPCCH). The E-AGCH carries an absolute uplink E-DCH grant (that is, the maximum power ratio between the E-DPDCH and a dedicated physical control channel (DPCCH)). The channelization code for the E-AGCH is signaled separately for each UE. The E-RGCH carries a relative uplink E-DCH grant. The E-HICH carries an E-DCH H-ARQ recognition indicator (ie, ACK or NACK). The E: DPDCH carries HSUPA uplink data packets. The E-DPCCH carries transport format combination index (TFCI) information, a retransmission sequence number (RSN) and a bit of agreement. i The following Tables 1 and 2 summarize the control information sent in the downlink for HSDPA and HSUPA, respectively, and the following Tables 3 and 4 summarize the control information sent in the uplink for HSDPA and HSUPA, respectively.

A B-node assigns at least one downlink control channel and at least one uplink control channel to a wireless transmitter / receiver unit (WTRU). The downlink control channel and the uplink control channel are provided to carry control information for both downlink and uplink data transmission. Conventional control channels for HSDPA and HSUPA are combined in a small set of control channels for uplink and downlink I. The B-node and the WTRU communicate the control information via the reduced set of downlink control channels and uplink control channels. The WTRU receives downlink data and transmits uplink data and the B-node receives I uplink data and transmits downlink data based on the control information transmitted via the reduced set of downlink control channels and of uplink control.

Figure 3 is a flow chart of an exemplary method for transmitting control and data packets according to another embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES i When referenced in the following, the terminology "WTRU" includes but is not limited to a user equipment (UE), a mobile station (STA), a fixed or mobile subscriber unit, a pager or any other type of device able to operate in a wireless environment. Where reference is made to the following, the terminology "node-B" includes but is not limited to one (base station, e-node-B, a site controller, an access point (AP) or any other type of interconnection device in a wireless environment The features of the present invention can be incorporated into an integrated circuit (IC) or can be configured in a circuit comprising a multitude of interconnecting components. In the current 3GPP specification, there are four downlink control channels and two uplink control channels that are defined to support HSDPA and HSUPA operation. According to the present invention, the two conventional uplink control channels are combined with at least one uplink control channel and the four conventional downlink control channels are combined with at least one control channel of downlink. In addition to these control channels used for uplink and high-speed downlink, it is also possible to combine signaling information on associated dedicated control channels (eg transmission power control (TPC) over the uplink and the downlink DPCCH ). Figure 1 is a block diagram of a wireless communication system 100 configured in accordance with the present invention. The system 100 includes a node B-102 and a WTRU 104. Between the B-node 102 and the WTRU 104, an uplink control channel 112, a downlink control channel 114, a data channel 116, are established. downlink and an uplink data channel 118. Channels 112-118 are assigned to the WTRU 104 preferably by the B-node 102 or a radio network controller (RNC). Channels 112-118 can be defined by a combination of at least one frequency, time, energy, antenna and code. A certain antenna and power can be used to transmit to a user and a different antenna and power set can be used to transmit to another user. Therefore, multiple channels may be available at the same time on the same frequency and code using both a different antenna and energy. The B-node 102 can be configured to the WTRU 104 to receive and transmit on more than one downlink and uplink control channel and more than one downlink data channel t and uplink. The WTRU 104 listens to the downlink control channel 114 and obtains control information about the downlink data channel, the uplink control channel and the uplink data channel. Once the WTRU 104 is configured with the uplink control channel 112 and the downlink data channel 116, the WTRU 104 receives data or transmits control and data information over the assigned downlink data channel 116. , the uplink control channel 112 and the uplink data channel 118.

The control information may include programming information, packet decoding information, reception procedure information and feedback information. The packet decoding information, the procedure i receiving information and the feed back information 1 need to be transmitted every transmission time interval (TTI). The programming information can be transmitted each TTI on a basis as needed. The packet decode information may include modulation scheme, a coding rate and a packet size. The information regarding the modulation scheme, the coding rate and the packet size can be combined in a parameter about the air transmission. | The reception procedure information may include the H-ARQ procedure ID, a new data indicator, a redundancy version, a packet sequence number and status information of a transmitter. The procedure ID H-ARQ is only needed for asynchronous H-ARQ and is not needed for synchronous H-ARQ. You can use the redundancy version to also indicate new data. The packet sequence number indicates the sequence number of a packet within an H-ARQ procedure as the transmitter. East it is a useful parameter for the soft or hard combination of 'retransmission and a transmission that has previously failed. The status information can be used for ARQ operation assisted by H-ARQ where together with the H-ARQ feedback information it indicates the transmission status that is being carried out which can be reported. The feedback information may include ACK / NACK of H-ARQ, a CQI of the control channel, a CQI of the data channel, a packet sequence number, an H-ARQ procedure ID, status information of a receiver, transmission diversity information (phase and amplitude information to support transmission diversity) and energy control information. The programming information is a programming request or a programming response. The programming response is sent from the B-node 102 to the WTRU 104 and the programming request is sent from the WTRU 104 to B-node 102. The scheduling response may I include at least one of resource allocation for a secondary downlink control channel (if applicable), resource allocation for downlink data channel 116 , allocation of resources for the uplink control channel 112, allocation of resources for the uplink data channel 118 and uplink timing adjustment, if necessary. The downlink control channel; Secondary is a control channel dedicated to a WTRU 104 for point-to-point services and possibly for several1 WTRU in the case of multiple point-to-point services. The WTRU 104 listens and decodes the channel after a resource allocation indicating the secondary control channel. The WTRU 104 needs frame alignment timing for. transmit correctly in an uplink interval. Since a clock of the WTRU 104 is derived with time and the propagation delay changes due to mobility, the WTRU 104 needs to adjust its clock based on the feedback of the node B-102. This information is signaled whether the B-102 node detects reception outside a specified interval. 'In conventional 3GPP standards or standards; radio resources are allocated by TTI for HSDPA and indefinitely for HSUPA. A duration field can be added to provide flexibility in assigning radio resources so that each resource allocation includes physical resource allocation information and duration indicating a period during which physical resource allocation is in effect. The duration may be a continuous assignment of certain TTIs for WTRU 104 or a periodic allocation of resources for a certain time. For example, the duration field can be indicated by "n" TTI where "n" can have a value from 1 to infinity. The value of "1" indicates that the resource is assigned for a TTI and the value of "infinity" indicates infinite allocation of the resource. When resources are allocated for an infinite period, WTRU 104 is explicitly informed about the release of resources. i The programming response can be sent separately in the downlink control channel 114.

Alternatively, the programming response can be multiplexed into a signal packet with at least one of the packet decode information, the receive processing information and the feedback information. Alternatively, the programmed response can be loaded with a data packet and sent on the downlink data channel 116. Alternatively, two separate downlink control channels can be assigned to the WTRU 104 (i.e. a primary downlink control channel and a secondary downlink control channel) and the programmed response can be transmitted-via the primary downlink control channel and the other control information (i.e., packet decode information) , information of reception procedures I, timing adjustment and feedback information) which can be transmitted via the secondary downlink control channel. Is; preferable to share the link control channel, primary downstream i with multiple WTRUs and dedicate the secondary downlink control channel1 to a single WTRU for point-to-point services or a WTRU set for multiple point-to-point services. The primary downlink control channel is a common control channel that is listening to the entire WTRU. The secondary control channel is a dedicated control channel that is listening to certain WTRU addressed to a particular primary control channel. The programming request may contain all or part of the following information such as buffer occupancy for each type of service or data flow, quality of service requirements (QoS) related, time in the row for the first packet for each service and the free space of energy WTRU (that is, the available power for the requested uplink resource channel). The programming request can be transmitted separately in the uplink control channel 112, can be loaded with other control information and transmitted on the uplink control channel 112, can be loaded with uplink data and transmitted over the uplink data channel 118 can be sent via a separate packet in uplink link data channel 118 or may be sent via a random access channel (RACH) (not shown in Figure 1). Preferably, during the active transmission (i.e. the uplink control channel 112 is present) the programming request is sent over the uplink control channel 112 loaded with the other control information. In the absence of the uplink control channel 112, the scheduling request is preferably sent in the RACH. In order to transmit control information on the uplink control channel 112 and the downlink control channel 114, the control information may be separated into two parts since not all of the control information needs to be sent at any given TTI . The control information may contain special bits to indicate whether a control channel contains only downlink control information or only uplink control information and whether the control channel contains feedback information or other control information. Special habits can also indicate whether the control channel includes broadcast information, multimedia broadcast / broadcast services (MBMS), persistent programming information for periodic services; Location or information information or control for WTRU group. The uplink control information from the B-node 102 to the WTRU 104 may contain transmission feedback information. The downlink control information from the WTRU 104 to the B-node 102 only contains feedback information. The uplink control information from the WTRU 104 to the B-node 102 contains packet decode information, receive processing information and schedule request (if needed). The downlink control information from the B-node 102 to the WTRU 104 contains decoding information, reception processing information and a protocol response (if needed). ' In a preferred embodiment, a single package that includes all of the control information may be used.

Alternatively, multiple i packages can be used. A single packet contains all of the downlink control information and the uplink control information necessary for the downlink and the uplink. The control pack contains decoding information; reception procedure information, information of feedback and programming information (ie, a programming request or a programming response). Some indication may be included in the control packet to indicate active information elements. The downlink control channel 114 and the uplink control channel 112 may be a shared channel for all WTRUs or a dedicated channel assigned to a single WTRU or a WTRU group. Preferably, the uplink control channel 112 is not a shared channel due to possible collisions between multiple WTRUs. The uplink control channel 112 can be assigned to a WTRU 104 only during the uplink or active downlink data transfer (i.e., on a base as needed). Alternatively, the uplink control channel 112 can be assigned to a WTRU 104 even in a state of inactivity. Table 5 summarizes four alternatives with respect to a downlink and uplink control channel configuration. Method 3 and 4 are the preferred alternatives.

Table 5 An exemplary system operation with a single downlink control channel and a resource allocation per TTI base is explained in the following with reference to Fig. 2. Fig. 2 is a flowchart of an exemplary method 200 for transmission of control and data packets, according to one embodiment of the present invention. The WTRU listen to the downlink control channel 114 (step 202). Once the WTRUs 104 obtain the control information directed to them in the link control channel 114 descending from a B-node 102, the WTRU 114 acquires programming information (eg allocation of resources for a downlink data channel, an uplink control channel and an uplink data channel) and decoding package and reception procedure information (e.g., a coding rate, a modulation scheme, a packet size, an H-ARQ procedure ID, a redundancy version or the like). The control packet may also include feedback information (ie, ACK / NACK of H-ARQ from the previous uplink data packet and a CQI). The WTRU 104 receives the programming information and configures the downlink data channel 116, the uplink control channel 112 and the uplink data channel 118 (step 204). The B-node 102 transmits a downlink data packet to the WTRU 104 via the downlink data channel 116 (step 206). The WTRU 104 receives the i downlink data packet on the downlink data channel 116 and decodes and processes the data packet based on the packet decoding and reception procedure information received in the control packet via the downlink control channel 114 (step 208).

The WTRU 104 responds with a control packet containing feedback information for the 'downlink data packet (ie, ACK / NACK)' (step 210). If needed, the WTRU 104 may also send a schedule request for uplink transmission and packet decoding and reception procedure information (i.e., a coding rate, a modulation scheme, a packet size, an ID). of procedure H-ARQ, an i redundancy version or similar) and can subsequently send an uplink data packet (stages 210, 212). The B-node 102 receives and processes the uplink data packet from the WTRU 104 using control information in the received control packet i via the uplink control channel (step 214). An exemplary system operation with primary and secondary downlink control channels and allocation of resources based on duration is explained herein with reference to Figure 3. Figure 3 is a flowchart of an exemplary method 300 for transmission of control and data packets according to another embodiment of the present invention. There are two downlink control channels (i.e., a primary downlink control channel and a secondary downlink channel). You know the primary control channel (also called common control channel) and monitored by each WTRU 104. Each WTRU 104 receives control information regarding the primary channel addressed thereto from the B-node 102. The B-node 102 sends programming information on the primary downlink control channel (step 302). The programming information includes resource allocation for a secondary downlink control channel, a downlink data channel, an uplink control channel and an uplink data channel. The secondary downlink control channel is the dedicated control channel directed to the WTRU 104. Upon receipt of programming information, the WTRU 104 configures the secondary downlink control channel, the downlink data channel, the Uplink control channel and the uplink data channel (step 304). The B-node 102 sends control information (i.e., packet-related information, such as coding rate, a modulation scheme, a packet size, an H-ARQ procedure ID, a redundancy version or the like) on the secondary downlink control channel (step 306). The B-node 102 can send feedback information (ie, ACK / NACK of the previous uplink data packet and a CQI) on the secondary downlink control channel. The B-node 102 then sends a data packet to the WTRU 104 via the downlink data channel, (step 308). The WTRU 104 decodes and processes the data packet based on the control information received in the secondary downlink control channel (step 310). The WTRU 104 sends a control packet that contains feedback information to the data packet (ie, ACK / NACK) via the uplink control channel (step 312). If needed, the WTRU 104 can send a scheduling request for uplink transmissions and packet related information together with the feedback via the uplink control channel. The WTRU 104 may then send an uplink data packet via the uplink data channel (step 314). The B-node 102 receives, decodes and processes the uplink data packet based on the control information received via the uplink control channel (step 316) J If the primary control channel allocates a secondary channel for transmission control and data for a duration specified for the WTRU 104, either continuously (ie, each TTI) or periodically (i.e., according to a receiving pattern over multiple TTIs) receives the assigned channels for the duration of the assignment.

An H-ARQ control package for a procedure; H-ARQ can be sent on a basis as needed. If the H-ARQ information (such as the H-ARQ procedure ID, a new data indicator and a redundancy version) is included in a subsequent packet (for example in a header of a subsequent data packet) there is no need to send programming information every TTI. A downlink control packet for programming information will be sent only if there is a change in resource allocation, a modulation scheme or a packet size.

«The control information can be loaded into a data packet. The control information (such as ACK / NACK, a CQI, a programming response or a programming request) can be loaded with data in a data packet. This is especially useful when both the uplink and downlink H-ARQ procedures are active. A downlink data packet can be loaded as ACK / NACK, a CQI and a programming response. An uplink data packet can be loaded as ACK / NACK, a CQI and a programming request. Alternatively, two uplink control channels can be provided (ie, a primary uplink control channel and an uplink channel). secondary uplink control). The primary uplink control channel is used to send a request for resources and the secondary control channel is used to send packet decoding information and reception procedures as well as feedback information. i The downlink resource allocation may implicitly imply allocation of uplink resources. For example, when the WTRU 104 is assigned with resources in the downlink for HSDPA, and implicitly it can mean that specific resources are assigned in the uplink for data or transmission of control (such as ACK / NACK, small data packets and request for programming for uplink transmission). The uplink data channel and the uplink control channel may have a fixed time or frequency offset from the downlink data channel or the downlink control channel and the WTRU 104 may configure the downlink data channels. uplink based on fixed deviation. i The B-node 102 can make the decision regarding the transmission power, the packet size, a modulation scheme, the coding rate and an H-ARQ procedure for link transmissions upward. In this case, the control information for the uplink data packet is sent from the B-node 102 to the WTRU 104 via the downlink control channel. The WTRU 104 is required to monitor the downlink control channel. If a Time Division Multiplexing (TDM) system exists, the WTRU 104 may also change to inactivity during the time intervals in which it is not assigned to the WTRU 104 and may be activated to listen to the control channel in the time intervals. allocated time.
