Abstract

A method and system for implementing hybrid automatic repeat request (H-ARQ)-assisted automatic repeat request (ARQ) in a wireless communication system are disclosed. When an H-ARQ negative acknowledgement (NACK)-to-positive acknowledgement (ACK) error occurs, the H-ARQ receiver sends an H-ARQ NACK-to-ACK error indicator to the H-ARQ transmitter unless a maximum retransmission limit has reached, a maximum time for delivery has expired or a lifespan of the failed packet has expired. The H-ARQ transmitter sends a local NACK to the ARQ transmitter so that the failed packet is recovered at an ARQ level. The H-ARQ receiver sends a local NACK to the ARQ receiver if the H-ARQ receiver does not receive the failed packet before certain conditions occur. The ARQ receiver may send a status report to the ARQ transmitter for recovery of the failed packet.

Description

201018130 VI. Description of the Invention: [Technical Field of the Invention] The present invention/step and wireless communication system. In particular, the present invention relates to a method and system for implementing Automatic Repeat Request (ARQ) assisted by Hybrid Automatic Repeat Request (H_ARQ) in a wireless communication system. [Prior Art] In the wireless communication system such as Broadband Code Division Multiple Access (WCDMA) version 5/6, 'High-speed data transmission is through High Speed Downlink Packet Access (HSDPA) and Fast Uplink Packet Access (HsupA) technology is implemented. In order to improve the reliability of data transmission, Η# was implemented. with. Figure 1 shows a conventional wireless communication system. The system 1 includes a user beta (UE) 110, a node b 12 〇, and a radio network controller (Zhe). The Η-ARQ entity is located at the media access control (L2) layer n2 of U£ii〇. And the MAC layer 122 of the Node B 120. The packet is assigned the transmission sequence number (TSN) in the H ARQ transmitter. The η-ARQ receiver receives the packet and tastes and decodes the transmitted packet. If the packet cannot be decoded, then the Η-ARQ will receive a negative acknowledgement (NACK) to the Η-ARQ transmitter to retransmit the failed packet. If the packet is decoded correctly, the H_ARQ receiver will send an acknowledgement (ACK) to the H_ARQ transmitter for the packet. When a NACK is received, 'if the number of retransmissions of the failed packet is less than the predetermined maximum, and the allowed transmission timing of the failed packet has not expired, the h_arq transmitter will retransmit the packet. The side of the lost Lin Baoshun discards the county ARQ level recovery. The ARQ entity is located at Radio Link Control (RLC) layer n4 of UE 110 and RNC 130 ❸ RLC layer 132. The ARQ entity retransmits the failed packet 4 201018130 because of the _-pair packet. In the stenciling, the class processing is prepared, and it has many options for implementing status reporting. When the H-ARQ and the Qing function coexistence system (_Ts) + _B or the long term evolution (La) evolution point B, an H-ARQ-assisted ARQ operation can be considered at this time. Figure 2 shows an example of the borrowing & H_ARQ _ 卩 operation for the 3rd Generation Partnership Project (3GPP) standard. The transmitter 25A includes an ARQ transmitter 252 and an H_arq transmitter 254. The receiver 26A includes an ARQ receiver 262 and an H-ARQ receiver 264. The H_ARQ transmitter 254 provides a local ACK or local NACK for the ARQ poller 252.

- As shown in Fig. 2, the 'local NACK' is generated when the transmitter 2M cannot complete the H-ARQ transmission (for example, the maximum retransmission). The ARQ transmitter 252 transmits an ARQ protocol data unit to the H-ARQ transmitter 254 (PDUX step 2〇2 > the H-ARQ transmitter 254 then transmits this ARQ PDU ❿ X to the H_ARQ receiver 264 (step 204). The ARQ PDU X is unable to be decoded 'and the H-ARQ receiver 264 will send a NACK to the H-ARQ transmitter 254 (step 206). The H-ARQ transmitter 254 then retransmits the ARQ PDU to the H-ARQ receiver 264. X (step 208). However, the ARQ PDU x is still unable to decode 'and the H-ARQ receiver 264 will send another NACK to the H-ARQ transmitter 254 (step 210). At this time, the ARQ PDU x is retransmitted. The number of times is determined to have reached the maximum retransmission limit (step 212). Then the 'Η-ARQ transmitter 254 sends a local NACK for the ARQ PDUx to the ARQ transmitter 252 (step 214). 201018130 In addition, the local NACK can also be in the H- The ARQ receiver 264 generates a NACK to ACK error when reporting to the H-ARQ transmitter 254. Still referring to Figure 2, the ARQ transmitter 252 transmits an ARQ PDU y to the H-ARQ transmitter 254 (step 216). H-ARQ Transmitter 254 then sends the ARQ PDU y to the Η-ARQ receiver 264 (step 218). The ARQ PDU y cannot be decoded and the Η-ARQ receives The 264 will send a NACK to the Η-ARQ transmitter 254 (step 220). However, the 'NACK is misjudged as ACK by the Η-ARQ transmitter 254, and the Η-ARQ transmitter 254 regards the ARQ PDU y as being successfully transmitted. The Η-ARQ receiver 264 detects a NACK-to-ACK error (eg, when the Η-ARQ receiver 264 receives a new PDU via the same Η-ARQ process while waiting for PDU ARQ y retransmission), step X 222) The h-arq receive 264 will send a NACK-to-NACK error indicator to the H-ARQ transmission benefit 254 (step 224). Upon receiving the NACK-ACK error indicator, the Η-ARQ transmitter 254 will forward to the ARQ transmitter. 252 sends a local NACK, and the ARQ PDU y is recovered at the ARQ level (step 226). As shown in FIG. 2, the local ACK is generated when no such event occurs in the predetermined timing interval regarding the above two events of the ARQ packet. arQ transmitter

252 sends an ARQ PDU z to the Η-ARQ transmitter 254 (step 228 > H-ARQ transmitter 254 then transmits this ARQ PDU z to receiver 364 (step 230). The ARQ PDU z is successfully decoded and H_ARQ is received The 264 will send the ARQ PDU z to the ARQ receiver 262 (step 232) and send an ACK to the Η-ARQ transmitter 254 (step 234).

It is determined that when the ACK error is not reported in the predetermined timing_ (step 236), the H-ARQ transmitter 254 transmits a local ACK 6 201018130 to the ARQ transmitter 252 (step 238). Upon receiving the local ACK from the H-ARQ transmitter 254, the ARQ transmitter 252 discards the packet from the transmit scratchpad.

In the above example of an ARQ system assisted by H-ARQ, where the complex second layer (L2) status reporting mechanism is removed by assuming that the NACK is an ACK error as the only significant source of missed packet loss. If the NACK loses the ACK error indicator or the shared channel is lost due to a discontinuous transmission (DTX) / ACK error, the ARQ transmitter will not be able to recover the packet. Thus, lossless transmission is not guaranteed. The current downlink Η-ARQ (version 5) does not specify the maximum number of retransmissions of the packet. Therefore, the Η-ARQ transmitter or receiver does not know the maximum number of retransmissions per packet. It is assumed that the ARQ transmitter and the η-ARQ transmitter have the same PDU size. The Η-ARQ transmitter will inform the Η-ARQ receiver of the lost segment (not the mq PDU). If the arq pDU is retransmitted, then the h arq transmitter will be heavy (four) packets are only missing segments. In addition, it is unclear how to recover the last packet of the Η-ARQ transmission. SUMMARY OF THE INVENTION Umbrellas are involved in a method and system for implementing h_ar in a wireless communication system. The receiver determines whether an appearance occurs. H-ARQ NACK vs. ACK error. When an H_ARQ NACK pair error occurs Unless the number of retransmissions of the lost package exceeds the maximum retransmission limit, the maximum delivery timing of the failure * ^ expires and/or the failure of the seal (10) expires, ·Η-ΑΚ(^ will be H_ARQ miscellaneous n money, fine == will try to recover the failed packet. If the maximum retransmission limit, the maximum delivery time expires or the failed packet expires, then the Η-ARQ transmission sends a local NACK to the ARQ transmitter in order to recover at the ARq level. Packet. If the H-ARQ receiver does not receive a failed packet before a certain condition occurs, then the H-ARQ receiver will send a local NACK to the ARQ receiver. Based on the reception of the local NACK, the ARQ receiver can go to the ARQ transmitter. The status report is transmitted to recover the failed packet. [Embodiment] The features of the present invention can be introduced into an integrated circuit (IC) or can be configured in a circuit including a large number of interconnect elements. In accordance with the present invention, a transmission map of a process for performing an ARQ operation assisted by H-ARQ is implemented in a wireless communication system 3. The system 3 includes a transmitter 310 and a receiver 320. The transmitter 31 includes Transmitter 312 and H-ARQ transmitter 314. Receiver 320 then includes ARQ receiver 322 and H-ARQ receiver 324. To support ARQ assisted by Η-ARQ in accordance with the present invention, the following parameters are defined herein: TErrorlndicator • The H-ARQ error indication timer is defined as the timing amount of the failed packet retransmission that the H_ARQ receiver should wait before transmitting the HARQ error indicator. To make the whole system easy to implement, it is better to keep 11_person 11 ( 5 The error indicates that the timer is constant. However, the H_ARQ error indication timer can also be adjusted based on quality of service (QoS) requirements. For example, the length of the h-mq error indication timer can be related to the scheduling priority. NRetransmisskm: is a packet The maximum number of retransmissions allowed. The maximum number of retransmissions can be based on Q〇S requirements, and can be assigned 201018130 TDelivery according to each service type: after the first transmission' The maximum transfer timing allowed by the work transfer packet. The maximum transfer order can be called (10) demand (_block error rate, wait timing, etc.), and can be configured according to each service type. TRecDverySyne: opposite step h_arq Said parameter is the timing range in which the receiver receives the failed packet after communicating the H-ARQ error indicator. TR_eryAsyne: For asynchronous H_ARq, this parameter is private. The timing range in which the packet is expected to be received after the ARQ error indicator is transmitted. This timer can be associated with the q〇s requirement and can be configured per service type. For example, the length of the timer can be related to the order of the keys.

Wharq. The window that should receive the failed packet (that is, the number of packets). If no failed packet is received within Wharq, the packet is assumed to be lost. In addition, the transmitter 310 and the receiver 32 can also be provided with parameters regarding the duration of the packet (i.e., the maximum timing of transmitting the packet). These parameters may be provided by the central node to the H-ARQ receiver 324 and the H-ARQ transmitter 314. If these parameters are defined in accordance with each service type, these parameters can be provided to the H-ARq receiver 324 and the H-ARQ transmitter 314 at the beginning of the service. The maximum number of retransmissions and/or the duration of the packet can be dynamically changed according to the demand of q〇s. The maximum number of retransmissions may be indicated either by explicitly identifying the number of transmissions in the associated transmission or by identifying a MAC flow associated with the configured maximum number of transmissions. According to a first option, the number of retransmissions per packet is indicated in the associated control transmission for the first transmission. According to the 201018130 first choice, 'each MAC stream can be associated with a certain number of retransmissions, and the maximum number of transmissions can be indicated by 'identifying the MAC stream' with the associated control for the first transmission. If the second option is used then the identified MAC stream will be converted to the maximum number of transmissions configured by the receiver. Furthermore, if a particular H-ARQ process is dedicated to a certain MAC stream in a group of MAC flows, then the maximum number of retransmissions can also be known via the h-ARQ process ID. Instead, a flag indicating the last transmission can also be set in the associated transmission of the cypress.

The processing of the HARQ operation assisted by H-ARQ in accordance with the present invention will be described hereinafter with reference to FIG. The H-ARQ transmitter 314 sends a packet to the H-ARQ receiver 324 (step 402). If the packet is successfully received, the H-ARQ receiver 324 will send the packet to the ARQ receiver 322 (not shown in Figure 3). If the packet is not successfully received then the H-ARQ receiver 324 will send a NACK to the H-ARQ transmitter 314 (step 404). After transmitting the NACK in step 404, the H-ARQ receiver 324 will determine if an h_ARq NACK to ACK error has occurred (step 406). Upon detecting an h-arq NACK pair ACK error, the H-ARQ receiver 324 will generate an h-ARQ NACK pair ACK error indicator and send it to the H-ARQ transmitter 314 (step 408). For synchronous H-ARQ transmission, the h-ARQ retransmission timing is known to the receiver. If the H-ARQ receiver 324 receives a new packet when it is expected to retransmit the failed packet, the H-ARQ receiver 324 will determine that a slave has occurred since the failed packet has been transmitted for the maximum number of retransmissions (^ Tender (^ to eight (: erroneous, and will send H-ARQ NACK to ACK error indicator. 201018130 For non-synchronous H-ARQ transmission, when the maximum number of retransmissions is not reached, at the H-ARQ receiver A timer TEiTOrIndicator will be set up 324, and the H-ARQ receiver 324 will send a NACK to the H-ARQ transmitter 314 in step 404. If the failed packet is successfully received before the timer TErrorhldieator expires, the timer TErrorIndicator will Reset to zero, and does not generate an H-ARQ NACK to ACK error indicator. If the H-ARQ receiver 324 does not successfully receive a failed packet before the 5th timer TEnOrIndieatOT expires, then φ unless the number of transmissions of the failed packet has been reached The maximum retransmission limit, the maximum packet transfer timing (TDeIiveiy) expires, and/or the failed packet expiration expires, otherwise the η_α^ receiver 324 determines that an H-ARQ NACK-to-ACK error has occurred. And an H-ARQ NACK pair ACK error indicator is sent to the H-ARQ transmitter 314. The H-ARQ NACK pair ACK error indicator is sent from the H-ARQ receiver 324 to the H-ARQ transmitter 314, which advertises The NACK on the h-arq transmitter 314 misjudges the ACK. The H-ARQ NACK vs. ACK error 指示符 indicator is associated with a particular H-ARQ process and a particular packet in the H-ARQ process. The H-ARQNACK pair The ACK error indicator contains the h_ARq processing identifier (ID) and the TSN used to identify the packet ID in the H-ARQ process. For synchronous ARQ, since a fixed timing relationship between the failed transmission and the error report can be used The H-ARQ NACK pair ACK error indicator is associated with the H-ARQ process and the packet TSN, so the process of throwing the TSN can be removed. For example, if there are four (4) synchronous H-ARQ processes, Then a NACK to ACK error can occur and receive 201018130

Then send the H-ARQ NACK pair ACK to TSN as the timing error indicator of the packet. The H-ARQ NACK pair ACK error indicator can be operated independently of h_arq. This is done by sending the faulty (four) sequence of processing identifiers (if needed) and timing offsets. Instead, the h_net NACK-to-ACK error indicator can be sent as a physical layer signal on a fixed timing offset after receiving the received error packet.

If more than one packet can be sent from the transmitter 310 to the receiver 32, then the packets will have their own cyclic redundancy check (CRC) and can be sent using an H-ARQ NACK to the ACK error indicator. The NACK of multiple packets indicates an ACK error. Thus, the NACK-to-ACK error indicator can include multiple processing IDs, associated packet TSNs, and/or timing offsets. The H-ARQ NACK may also have its own CRC' for the ACK error indicator to ensure reliable transmission. This allows the gc or RLC layer to be sent for H-ARQ NACK versus ACK error indication. The H_arq NACK ❹ packet for the ACK error indicator can be created either at the H-ARQ level or at the ARQ level. Still referring to FIG. 3' to ensure that an H-ARQ NACK pair ACK error indicator is received', the H-ARQ transmitter 314 can send an ACK to the H-ARQ receiver 324 (step 410). The H_ARQ receiver 324 may repeatedly transmit an H-ARQ NACK pair ACK error indicator before the H-ARQ receiver 324 receives an ACK from the H-ARQ transmitter 314 or the radio link fails. 12 201018130 After receiving the H-ARQ NACK pair ACK error indicator at step 4G8 t, the H-ARQ transmitter 314 will pass the retransmission unless the maximum number of retransmissions is reached, the maximum delivery timing expires (four), or the failed packet expiration period expires. The failed packet attempts to fix the error at the H-ARQ level (step 412). The H_ARq transmitter 314 can send a local ACK to the ARQ transmitter 312 to recover the failed packet at the ARQ level (step 414). Preferably, the Η-ARQ transmitter 314 transmits the local NACK to the ARQ transmitter 312 only if the maximum retransmission-number of people, the burst transfer timing of the failed packet expires, or the expiration of the failed packet expires. In the prior art, upon successful delivery of the packet, the Η-ARQ receiver 324 will send an ACK to the Η-ARQ transmitter 314 and the Η-ARQ transmitter 314 will send a local ACK to the ARQ transmitter 312. In accordance with the present invention, in this case, the Η-ARQ transmitter 314 may either transmit a local ACK to the ARQ transmitter 312 or may not transmit. After the η-ARQ NACK pair ACK error indication is transmitted in step 408, the Η-ARQ receiver 324 determines in step 416 whether the Η-ARQ receiver 324 has occurred before at least one of the following conditions Successfully received a failed packet: 1) TRec〇verySync (corresponding to synchronous Η-ARQ transmission) or TRecoveryAsync (corresponding to asynchronous Η-ARQ transmission) has expired; 2) Received sequence number higher than Wharq of failed packet sequence number New H-ARQ packet; 3) Maximum number of retransmissions to reach the failed packet; 4) Timer TDeliveiy expires; and 13 201018130 5) The expiration of the failed packet expires. If at least one of the foregoing conditions occurs, the receiver 324 sends a local NACK to the ARQ receiver 322 (step 418). Upon receipt of the local NACK' ARQ receiver 322, a status report can be sent to the ARQ transmitter 312 to recover the failed packet (step 420). The mapping between the ARQ PDU and the H-ARQ PDU is irrelevant when the receiver 324 is able to identify the arq pdu that needs to be recovered. After receiving the status report from the ARQ receiver 322, the ARQ register on the transmitter 312 can be emptied. The report on the failure packet contains information about the packets that were successfully received. Alternatively, ARQ receiver 322 may also send a status report after successfully receiving N consecutive packets or expiring the timer. Alternatively, Arq transmitter 312 can also poll ARQ receiver 322 after transmitting the last packet in the scratchpad. The original purpose of implementing the polling is the NACK-to-ACK error of the last-packet of the H_ARQ峨 early ship. For the data flow, 'Setting the polling bit for the last packet' is a configurable parameter. 0 In order to improve the recovery process of the last packet in the Η-ARQ transmission, a special small packet having the last packet indication may be transmitted from the H_ARQ transmitter 314 after the Η-ARQ register is cleared. By transmitting this special packet with the last packet 4, it is ensured that the last lost packet is recovered earlier on the H_arq level. Upon receiving this special packet, the receiver 324 will send a response back to the Η-ARQ transmitter 314. The response packet may be a new packet generated at the Η-ARQ level to indicate receipt of the last packet. Alternatively, the response packet may also be sent by using a packet-like error indication 14 201018130 packet where the H-ARQ error indication packet indicates that it is a response to the small packet. Instead of reducing the excessive signaling, when the last data packet in the H-ARQ transmission queue invokes the previously transmitted ACK check, an empty transmission can be sent at this time. Empty packets contain only control information (that is, no bearers). The H-ARQ transmitter 314 will transmit an empty packet after receiving the H-ARQ ACK of the last data packet in the H-ARQ transmission queue. Once the h-arq receiver 324 receives the empty packet, the H-ARQ receiver 324 will acknowledge receipt of the last data packet and the empty packet. If the last packet is not successfully received on the receiver, and thus the NACK is sent in response to the last packet, and the maximum number of transmissions has not been reached at this time, then by receiving the empty packet, it can be made The H-ARQ receiver 324 detects a NACK to ACK error. Transmitter 310 and receiver 320 may be WTRUs, base stations, or any of the WCDMA, CDMA2 or third generation (3G) system long term evolution (LTE).
