The present invention is related to wireless communication systems. More particularly, the present invention relates to an enhanced dedicated channel (E-DCH) scheduled transmission method and apparatus.

The improved uplink (UL) coverage, output and transmission latency methods are currently being investigated in the 3rd Generation Partnership Project (3GPP). In order to achieve these goals, Enhanced Uplink (EU) transmission has been proposed in the Third Generation Partnership Project, where the uplink resource (ie physical channel) control (ie scheduling and dispatching) is from the wireless network controller ( RNC) was moved to Node B.

FIG. 1A shows a conventional wireless transmit/receive unit (WTRU) (eg, mobile station), side media access control (MAC) architecture 100. The WTRU-side media access control architecture 100 includes a media access control-es/media access control-e entity 105 that includes different independent sub-layer entities within the media access control. Media Access Control - es/-e Functional Segmentation is the result of how media access control functionality is partitioned into the Universal Terrestrial Radio Access Network (UTRAN). The WTRU 100 media access control architecture 100 further includes a high speed media access control entity 110, a media access control-c/sh 115, a dedicated channel media access control (MAC-d) 120, and a medium. Access Control Service Access Point (SAP) 125. The Media Access Control-c/sh 115 can control access to all shared transmission channels except the High Speed Downlink Shared Channel (HS-DSCH) 145. The dedicated channel media access control 120 can control access to all dedicated transmission channels, media access control -c/sh 115 and media access control -hs110. The Media Access Control-hs110 can control access to the High Speed Downlink Shared Channel 145.

Media Access Control - es / Media Access Control - e entity 105 can control access enhancement Dedicated channel 130, whereby media access control-d 120 can access enhanced dedicated channel 130 via connection 135, and media access control SAP 125 can access enhanced dedicated channel 130 via connection 140.

Fig. 1B shows the media access control interaction operation in the conventional wireless transmitting/receiving unit of Fig. 1A. As shown in FIG. 1B, a Radio Link Control (RLC) Protocol Data Unit (PDU) is connected to the Media Access Control-d on a logical channel. In the Media Access Control-e header, the Data Description Indicator (DDI) field (6-bit) identifies the logical channel, media access control-d stream, and media access control-d protocol data unit size. The mapping table is transmitted on the Radio Resource Control (RRC) signal transmission to cause the WTRU to set the data description indicator value. The N field (6-bit fixed size) indicates the number of consecutive media access control-d protocol data units corresponding to the same data description indicator value. The data description indicator field special value indicates that no data is included in the remainder of the Media Access Control-e Agreement data unit. The Transmission Sequence Number (TSN) field (6-bit) provides the transmission sequence number on the enhanced dedicated channel 130 shown in Figure 1A. The media access control-e-protocol data unit is forwarded to a hybrid automatic repeat request (H-ARQ) entity, which then forwards the media access control-e-protocol data unit to layer 1 for use in a transmission time segment (TTI) Transfer.

An effective media access control architecture that enhances the scheduling of dedicated channel data transmissions is expected.

The invention relates to an enhanced dedicated channel scheduling method and apparatus. The scheduling power is calculated for the scheduled data stream. The remaining transmission power is calculated for enhanced dedicated channel transmission. A rate requirement message is generated in which the scheduled power, residual transmission power, and rate requirement messages are used to select Transport Format Combinations (TFCs) and multiplexed schedules for enhancing the transmission of dedicated channel transmissions. The remaining transmission power is enhanced by extracting the dedicated physical data channel (DPDCH), the dedicated entity control channel (DPCCH), the high-speed dedicated entity control channel (HS-DPCCH), and the uplink dedicated entity control channel (E-DPCCH) from the maximum allowable power. The power and power margin are deducted to calculate.

The present invention can be understood in more detail from the following description of the preferred embodiments, in which: FIG. 1A shows a conventional wireless transmission/reception unit side medium access control architecture; FIG. 1B shows a conventional wireless transmission/reception of FIG. Prior art media access control interaction operations in the unit; FIG. 2 shows a wireless transmit/receive unit media access control-e architecture configured in accordance with the present invention; and FIG. 3 is a media access control-e in accordance with the present invention Scheduling process flow chart; and FIG. 4 shows an example of pre-processing media access control-e protocol data unit format configured in accordance with the present invention.

Hereinafter, the term "wireless transmitting/receiving unit" includes, but is not limited to, a user equipment (UE), a mobile station, a fixed or mobile subscriber unit, a pager, or any other type of user device operable in a wireless environment. Hereinafter, the term "B Node" is used to include, but is not limited to, a base station, an address controller, an access point, or any other interface device in a wireless environment.

Thereafter, the "Media Access Control -e" noun will be used jointly to refer to Media Access Control - e and Media Access Control - es.

Features of the invention may be incorporated into an integrated circuit (IC) or configured in a circuit comprising multiple interconnected components.

Figure 2 shows a wireless transmit/receive unit media access control-e architecture 200 configured in accordance with the present invention. Wireless transmission/reception unit media access control-e architecture 200 includes a scheduling permission processing unit 210, a remaining transmission power calculation unit 215, and a rate The processing unit 220 is sought.

The schedule license processing unit 210 can receive at least one schedule license from at least one wireless link group (RLS) and drive the current schedule license. The schedule permission may be an absolute license 225 that is received from the service enhanced dedicated channel cell with primary and secondary identifiers (ie, the enhanced dedicated channel wireless network temporary identifier (E-RNTI) is used to determine the absolute license. Is a primary or secondary), a relative license 230 received from the service enhanced private channel radio link group or a relative grant 235 received from the non-service enhanced private channel radio link. The schedule permission processing unit 210 may output a signal 240 indicating the amount of scheduled power used in the enhanced transport format combination selection and the multiplex function for scheduling the data medium access control-d stream.

The amount of scheduled power can be identified as the ratio of the channel power to the dedicated entity. For example, if the dedicated entity controls the channel power to be P, the scheduled power amount has a ratio of 2 to the dedicated entity control channel power. The scheduled power is 2P. Alternatively, the scheduled power amount can be identified as being used to schedule the data to prevent the transmission format combination selection and multiplex function from paying attention to the maximum transmission power of the dedicated entity control channel power measurement. If the dedicated entity control channel power must be propagated to different entities within the media access control, there is processing overhead due to its rapid change. Furthermore, synchronizing time points is complicated. Therefore, since other scheduling related functions require current dedicated entities to control channel power knowledge, it is preferable to only one of the media access control-e that is aware of the dedicated entity controlling channel power.

When the media access control-e entity 105 motivates the media access control-e function, the schedule permission processing unit 210 can determine the current service license. The physical layer may provide an absolute grant 225 that is received from the AGCH, the signing permission being received by the primary or secondary enhanced private channel wireless network temporary identifier. The physical layer also provides a relative grant 230, 235 that is received from each radio link group, indicating that the radio link group is a service enhanced dedicated channel radio link group or a non-service enhanced dedicated channel radio link. The Absolute License 225 is sent as a ratio signal to the current uplink dedicated entity controlling the channel power. The current license is permanently reset by the absolute license 225 received by the primary enhanced dedicated channel wireless network temporary identifier. If the wireless network temporary identifier or permission setting is previously set to zero by the secondary enhanced dedicated channel, then Absolute permission to receive the temporary channel wireless network temporary identifier on the secondary channel only makes the current service license valid.

The relative license 230 from the non-service enhanced dedicated channel wireless link adjusts the service license in steps or steps. The relative license of the non-service enhanced dedicated channel radio link group can only reduce the service license in one step. When the relative grant from the non-service enhanced dedicated channel radio link group is received downward, the hysteresis period is initiated while other relative grants are being ignored.

The remaining transmission power calculation unit 215 can receive a signal 245 indicating the current dedicated entity control channel power estimated by the physical layer, indicating the dedicated channel transmission format combination selected by the media access control-d or the dedicated entity data estimated by the physical layer. The channel power signal 250 may indicate a high speed dedicated entity control channel active signal 255 from the physical layer and indicate the maximum allowed power (with power margin) from a Layer Management Entity (LLME) configured by the Radio Resource Controller (RRC). Signal 260. If the high-speed dedicated entity control channel is active, its power (and power from other channels) must be drawn from the maximum power to determine the remaining power. Based on the signals 245, 250, 255 and 260, the remaining transmission power calculation unit 215 can output a signal 265 indicating the remaining transmission power (Premain) calculated according to the following equation (1): Premain = Pallowed - PDPDCH - PDPCCH - PHS - DPCCH-PE-DPCCH-Margin; Equation (1) where PDPCCH, PDPDCH, PHS-DPCCH and PE-DPCCH represent dedicated entity control channels, dedicated entity data channels, high-speed dedicated entity control channels and enhanced uplink dedicated entity control channels, respectively. Power requirements. The rate requirement processing unit 220 can monitor the triggering event of the rate requirement and trigger the scheduling information rate request when the triggering event occurs. The rate requirement processing unit 220 can provide logic that can trigger rate requirements and logic that can construct a rate requirement message 270 that includes rate requirement bits.

When the new data is mapped to the logical channel of the enhanced dedicated channel, there is no current When the scheduling permission is received, the rate requirement can be triggered. The higher priority and the last reported new data is received on the logical channel mapped to the enhanced dedicated channel. When there is no current scheduling permission and the rate requirement is When updated and periodically generated (which is configured by the radio resource controller), the updated rate requirement is generated when the serving radio link group acknowledgement (ACK) is not received due to a previously transmitted rate requirement.

The rate requirement includes the total buffer occupancy of all scheduled media access control-d streams, the highest priority data buffer occupancy of any media access control-d stream, and the enhanced power headroom available for dedicated channel transmission.

Referring to Fig. 3, the media access control-e scheduling process 300 is explained as follows. The enhanced dedicated channel transmission time zone is monitored and it determines whether the scheduled information rate request triggers the occurrence and/or whether there is a licensed enhanced dedicated channel profile (step 302). If no rate request triggers or does not enhance dedicated channel data, then the process waits until the next transmission time segment. If the decision at step 302 is affirmative, then it is further determined whether there is available hybrid automatic repeat request processing (step 304). Before the enhanced transport format combination selection and enhanced dedicated channel data transmission, it is necessary to mix the automatic repeat request processing availability. If no hybrid automatic repeat request processing is available, then process 300 waits until the next transmission time segment. If the hybrid automatic repeat request processing is determined to be available at step 304, the current schedule grant and remaining transmit power calculations are respectively requested from the schedule grant processing unit 210 and the remaining transmit power calculation unit 215 (step 306). In step 308, the media access control-e control function cites the schedule and enhances the transport format combination selection function to generate a media access control-e protocol data unit. In step 310, the media access control-e-protocol data unit is then forwarded to the available hybrid automatic repeat request processing with the unique power offset and retransmission maximum number.

In a separate embodiment that satisfies the media access control-e-protocol data unit forming point requirements, the prior computing system that accelerates the possible media access control-e protocol data unit of the forming process is utilized. When the media access control-e entity is required to perform enhanced dedicated channel transmission with the remaining power budget, the forming process searches for a pre-formed media access control-e-protocol data unit table (ie, its formed media access control-e protocol) Data unit header and appropriate data area Block Agreement Data Unit) provides ready-made information to the hybrid automatic repeat request/physical layer. There are several methods of performing this prior processing depending on the time point requirements.

Figure 4 shows an example of a pre-processed Media Access Control-e protocol data unit format configured in accordance with the present invention. The pre-processed media access control-e-protocol data unit format contains a power budget that enhances the dedicated channel or equivalent, and is best suited to the fully formatted media access control-e-protocol data unit header of the budget or equivalent. Transmission Sequence Number (TSNs) and data block indicator list, schedule information and padding bits.

The power budget for the enhanced dedicated channel contains several expected powers or equivalents based on the final transmission power and current possible predictions. The Media Access Control-e-Agree data unit header is formatted based on this budget and the data priority on the same column. The fully formatted media access control-e-protocol data unit header is described in terms of logical channel prioritization, and the media access control-e-protocol data unit is described in consideration of scheduled and non-scheduled data and budget. The header contains a data description indicator, N and a data description indicator terminator. The media access control-es protocol data unit descriptor table column containing the transmission sequence number and the data index of the media access control-es corresponds to the same column pre-formatted protocol data unit header. If the schedule information exists, it can be combined with the Media Access Control-e agreement data unit. The padding bit indicates the number of bits that are filled at the end of the media access control-e protocol data unit for that particular column. Full Formatting can use some of the following information: Enhance the power budget for dedicated channels or equivalents, data description indicators, scheduled or non-scheduled. Such lists are based on data prioritization. Each column is a media access control-d stream (Media Access Control - es protocol data unit). The power budget is listed for the expected power budget. The data description indicator represents media access control - d stream identification, logical channel identification and protocol data unit size. The schedule or non-schedule field indicates that the contract data unit consumes a non-scheduled power budget or a scheduled power budget. Non-scheduled data can also be used in conjunction with scheduling information in the Media Access Control-e Agreement data unit.
