Description

1326167 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present disclosure relates generally to communications and, more particularly, to techniques for transmitting data in a wireless communication system. [Prior Art] A wireless multi-directional proximity communication system may include a number of Node Bs (or base stations) that support communication for a number of User Equipments (UEs). A Node B can communicate with multiple UEs on the downlink and uplink. The downlink key (or forward link) refers to the communication link 'from the Node B to the UE' and the uplink (or reverse link) refers to the communication link from the UE to the Node B. On the downlink, Node B can transmit data up to UEs using dedicated data channels and/or shared data channels. The dedicated data channel is assigned to a specific UE and is used to send data only to the data channel of the UE. The shared data channel is a data channel that is shared by multiple UEs and can be carried at any given time—or multiple UEs' data. A data channel is a mechanism for transmitting data and can rely on the radio technology used by the system. For example, in a code division multi-directional proximity (CDMA) system, a data channel can be associated with a particular channelization code (e.g., a particular Walsh code). Node B can use the shared data channel to achieve various benefits. The shared data channel allows for better use of available radio resources by serving each UE as needed and using just enough radio resources to feed the UE. Since all radio resources available for the shared data channel may be potentially used for one UE, the shared data channel can also support a higher peak data rate of ue. The shared data channel can also provide flexibility in UEs scheduled for data transmission on the downlink 115949.doc 丄 326167 link. Node B can signal a common control channel parallel to the shared data channel to communicate how the shared data channel is used. For example, 信号 'the signal notification can convey what (what) the UE is being servoed, configured to the radio resources of each UE being served, how to send data to each ϋΕ, etc. Due to the dynamic nature of the shared data channel, a UE potentially receiving data on the shared data channel can continuously monitor the shared control channel to determine if data is being sent to it. Each UE receiving a signal header on the shared control channel can process the shared data channel based on the received signaling to recover the data transmitted to the UE. The shared control channel represents an add-on to the shared data channel. SUMMARY OF THE INVENTION This document describes techniques for efficient data transmission and reception in a wireless communication system. According to one aspect, the UE receives transmissions on a data channel shared by a plurality of UEs. The UE processes the received transmission based on at least one parameter assigned to the UE 2 prior to receiving the transmission. According to another aspect, the UE receives transmissions on a data channel shared by a plurality of UEs during a time interval assigned to the U. The time interval is determined based on the individually selected pattern of time intervals suitable for transmitting data to U E . The UE processes the received transmission. According to the again-state, the UE signals the decoding on the control channel. If the signal is successfully decoded, the UE processes the received transmission based on at least the selected item parameter from the signal. If the decoding is not successfully signaled, the UE processes the received transmission based on at least one parameter 115949.doc 1326167 assigned to the ticket. [Embodiment] FIG. 1 shows a wireless communication system in which a plurality of Node Bs 11 and a plurality of UEs 12 are connected. The Node B is connected to a fixed station of the communication and can also be called a base. Enhance point B (eNode B), access point, and so on. Each node b provides communication coverage for a particular geographic area and supports communication for UEs located within the coverage area. The system controller 13 is coupled to the node b and provides coordination and control of the Node B. The system controller 13 is a single-network entity or a collection of network entities. For example, the system controller It may include helmet line grid control n(10)c), mobile switching center (msc), etc. ', ·, uE m may be dispersed throughout the system, and each UE may be fixed or (four). UE may also be called a mobile station , terminal, access terminal, user 70, desk, etc. The UE can be a cellular phone, personal digital assistant (test: wireless communication device, handheld device, wireless data machine, laptop, etc. UE) The pilots and signals may be actively communicated with the Node B or may be received only from the Node b. The terms "UE" and "user" are used interchangeably herein. Figure 2 shows a block diagram of Node B 110 and UE 12〇 It is the one of the 7th and the UE. At the Node B 11〇, the transmission (τχ) data processing...10 receives the traffic data from a data source (not shown) and from a controller. /Processing of the processor 240, processing (eg, formatting, encoding: interleaving and Symbol mapping) the traffic data and signal notification, and provide data symbols and signal notification symbols. The modulator 22 processes the data and signal notification symbols specified by the system and provides (4) W. Transmission (tmtr) 222 processing (for example, conversion) The analogy signals, amplification, transitions, and chirp conversions, the 115949.doc output chips and produce a downlink signal that is transmitted from the antenna 224. At the UE 120, the antenna 252 receives the downlink from the Node B 11 Linking the signal and providing the received signal to a receiver (RCVR) 254. The receiver is connected (eg, over, amplified, down-converted, and digitized) by the receiver and provides the received The sample demodulator (1) em〇d) 26 processes the received samples in a complementary manner to the processing performed by modulator 220 and provides symbol estimates. A receive (RX) data processor 27 processes (e.g., symbol maps, de-parsing and decoding) the symbol estimates and provides decoded information for the UE. On the uplink, at the UE 120, the data and signaling is processed by the D-data processor 290, modulated by the modulator 292, adjusted by the transmitter 294, and transmitted via the antenna 252. At node 8 11〇, the uplink signals from UE 12〇 and other UEs are received by antenna 224, adjusted by receiver 23〇, demodulated by demodulation transformer 232, and processed by *RX data processor 234. Restore the information and signal sent by the UE. In general, the processing of uplink transmissions can be similar to (or different from) the processing of downlink transmissions. Controllers 240 and 280 direct the operations at node b 11 and UE 120, respectively. The suffixes 242 and 282 store the data and code of the node b no and the UE 120, respectively. The techniques described herein can be used in a variety of wireless communication systems, such as code division multi-directional proximity (CDMA) systems, time-division multi-directional proximity (τε > μα) systems, frequency division multi-directional proximity (FDMA) systems, orthogonal FDMA (OFDMA) ) System, etc. The terms "system" and "network" are often used interchangeably. CDMA systems can utilize radio technologies such as broadband 115949.doc 1326167 CDMA (W-CDMA), cdma2000, etc. cdma2000 includes IS-2000, IS-856 and IS- The 95 standard. TDMA systems may utilize radio technologies such as the Global System for Mobile Communications (GSM). These various radio technologies and standards are known in the art. In one from the "Third Generation Partnership Program" W-CDMA and GSM are described in the literature of the organization of (3GPP). Cdma2000 is described in a document from an organization that is "3rd Generation Partnership Project 2" (3GPP2). For clarity, the following description W - Techniques for downlink transmission in CDMA systems. In W-CDMA, the UE's data is processed as one or more transport channels at a higher level. These transport channels can carry data for one or more services, such as Voice, video, packet data, games, etc. These transport channels are mapped to physical channels at a physical layer. These physical channels are channelized with different channelization codes and are orthogonal to each other in the code domain. 3GPP Release 5 and Later versions support High Speed Downlink Packet Access (HSDPA), which is a collection of channels and procedures that enable high speed packet data transmission on the downlink. For HSDPA, Node B is shared on high speed downlink. Transmitting data on the channel (HS-DSCH) 'The shared channel is a downlink transport channel shared by all UEs in terms of time and code. The HS-DSCH can carry one or more at a given transmission time interval (TTI) Information of one UE. A TTI is equal to one subframe of HSDPA and is the smallest time unit in which the UE can be scheduled and servoed. The sharing of HS-DSCH is dynamic and can vary between TTIs. Table 1 lists Used for some downlink and uplink physical channels of HSDPA and provides a short description of each physical channel. 115949.doc 1326167 Table 1 Keyway Channel Name Description Downlink HS-PDSCH High Speed Physical Downlink Sharing The channel carries the data transmitted on the HS-DSCH for different UEs. The downlink control channel of the HS-SCCH HS-DSCH carries the HS-PDSCH signal to notify the uplink HS-DPCCH HS-DSCH. Control channel carries HSDPA mid-downlink transmission feedback. For HSDPA, 'node b can use up to fifteen 16-chip channelization codes'. The sinus code has the expansion factor i6 for HS-PDSCH (sf=16). ). The Node B can also use any number of 12 8 chip channelization codes having a spreading factor i28 (SF = 128) for the HS-SCCH. The number of 16-channel channelization codes for HS-PDSCH and the number of 128-stone channelization codes for HS-SCCH are configurable. The channelization codes of HS-PDSCH and HS-SCCH are orthogonal variable expansion factor (OVSF) codes, which can be generated in a structured manner. The expansion factor (SF) is the length of the channelization code. A symbol is developed with a channelized code of length sf to produce an SF chip of the symbol. For HS-PDSCH, a UE can be assigned up to fifteen 16-chip channelization codes. For HS-SCCH, up to four 128-chip channelization codes can be assigned. The channelization codes of the HS-SCCH may be assigned to the UE at the time of call setup and signaled to the UE via upper layer signaling. The channelized codes of the HS-PDSCH are dynamically assigned and communicated to the UE via a signal transmitted on the HS-SCCH using one of the assigned 128 chip-coded codes. HSDPA can also be considered to have: (a) up to fifteen HS-PDSCHs, each HS-PDSCH using a different 16-code channelization code, and (b) any number 115949.doc 10 of HS-SCCH, each HS - SCCH uses a different 128 chip channelization code. In this case, one UE can be assigned up to four HS-SCCHs and up to fifteen HS-PDSCHs. In the following description, HSDPA can be considered to have: (a) - a single HS-PDSCH with up to fifteen 16-chip channelization codes, and (b) a single HS-SCCH with any number of 128 chips Channelization code. In the following description, the reference to the channelization code is used for the HS-PDSCH unless otherwise stated. Figure 3 shows the frame format in W-CDMA. The time table for transmission is divided into radio frames. The radio frame on the downlink is defined in a manner relative to the order of the Common Pilot Channel (CPICH). Each radio frame has a duration of 10 milliseconds (ms) and is identified by a 12-bit system frame number (SFN). Each radio frame is further divided into 15 slots, labeled slot 0 through slot 14. Each slot has a duration of 0.667 ms and includes 2560 chips at 3.84 million chips per second (Mcps). Each radio frame is also divided into five sub-frames: the sub-frame to the sub-frame 4. Each subframe has a duration of 2 ms and spans 3 slots. The sub-frame of the HS-SCCH is aligned with the radio frame time of the CPICH. The sub-frame of the HS-PDSCH shifts (or delays) two slots to the right relative to the sub-frame of the HS-SCCH. The HS-DSCH carries the transport block of the UE being servoed. The transport block is a block of data and may also be referred to as a data block, a packet, or the like. Each transport block is encoded and modulated and then transmitted on the HS-PDSCH. HSDPA supports Hybrid Automatic Retransmission (HARQ), also known as Incremental Redundancy (IR). Using HARQ, Node B sends a new transmission of a transport block and may send one or more retransmissions until a UE correctly retransmits the transport block 115949.doc 1326167, or encounters some other termination strip - A variable number of transmissions of the transport block. First, and each subsequent transmission is called retransmission. This means that $ can be changed after a previous pass, instead using sync m, and retransmitted on a previous pass. With synchronous and asynchronous IR, there is a time gap. During this time interval, the block is passed. The transmission of different round blocks can be coded or the maximum number of pieces sent. Node B can therefore send a transmission called a new transmission HSDPA supports an asynchronous jR, and the amount of time is transmitted repeatedly.

After a fixed amount of time is transmitted between consecutive transmissions of a transmission block, other transport areas may occur and thus interlace with HARQ. For HARQ in HSDPA, the node vomits privately, and ν then generates a cyclic redundancy check code (CRC) of one of the transport blocks, and attaches the CRC to the transport block. The mechanism or coding rate encodes the transport block and CRC'. Know the block coded in . After decoding, the coded block is divided into a plurality of redundancy versions using the product error punctuality B. Each Z-version version may contain different encoded information (or code bits) of the transport block. Node B can send a redundancy version for each transmission of the transmission block. In HSDPA, the defect B can select a sequence of redundancy versions to transmit for transporting the block. Lang point B is each transmission transmitted on HS-PDSCH in HS_SCCH^

Send a notification number 4. Table 2 shows the signalling sent on the HS-SCCH in HSdpa Reiease 5. The first line of Table 2 lists the information of the different blocks or types included in the signal notification, the second line gives the size of each block and the second line gives the content for each position. A short description. The fourth line is described below. 115949.doc 1326167 Table 2 - HS-SCCH Information HS-SCCH Intercept Size (Bit) Use HS-SCCH Not Use HS-SCCH Channelization Code Set 7 Refers to 120 possible channelization code sets not HS-PDSCH One channelized code is assigned to the UE before transmission on the HS-PDSCH. Modulation mechanism 1 indicates that QPSK or 16-QAM is fixed to QPSK transport block size 6 to select one of 254 possible transport block sizes. Two transport block sizes are assigned to the UE; by ue blindly determining for each transmission HARQ process number 3 indicates that the transport block being sent does not need 'because the use of synchronous IR redundancy version (RV) 3 indicates redundancy The remaining versions and modulations are not required because the use of synchronous IR with a redundant version of the fixed_sequence means that the current transmission is a redundant version of the retransmitted synchronous IR and fixed sequence of the previously received transmission. No need for the UE ID (UE ID) 16 to be sent with the signaling on the HS-SCCH to send the signal on the HS-SCCH along with the information on the HS-PDSCH including the transport format and resource related information (TFRI) and HA Information about RQ (or HARQ information). The TFRI includes a channelized code set, a modulation mechanism, and a transport block size. The HARQ information includes the HARQ process number, redundancy version, and new data indicator. The signaling is processed in two parts. Part 1 contains 8 bits for the channelized code set and modulation mechanism. Part 2 contains 13 bits for transporting block size and HARQ information. The CRC is calculated on Part 1 and Part 2. Part 1 is encoded with a rate 1/2 convolutional code, scrambled with the UE ID, and transmitted in the first slot of a subframe. Part 2 and CRC are encoded with a rate 1/2 convolutional code and transmitted in the last two slots of the sub-frame. This allows data transfer on ueshs-pdsch 115949.doc 1326167 to restore time critical information from Part 1 of HS-SCCH. Figure 4 shows the data transmission signaled on the HS-DSCH. The UE periodically estimates the received signal quality based on a pilot and transmits a channel quality indicator (CQI) on the HS-DPCCH. The Node B has the information to transmit to the UE and schedules the UE for downlink transmission. The Node B sends a signal to the UE on the HS-SCCH and transmits the first transmission of the transport block to the UE on the HS-PDSCH. The data transmission on the HS-PDSCH is delayed compared to the corresponding signaling transmission on the HS-SCCH. Two slots. The UE processes the HS-SCCH and signals the recovery to the UE. The UE then processes the HS-PDSCH based on the received signaling and restores the transport block sent to the UE. If the transport block is correctly decoded, the UE sends an acknowledgment (ACK) on the HS-DPCCH, otherwise a negative acknowledgment (NAK) is sent. The UE also estimates the received signal quality and sends a CQI along with the ACK or NAK on the HS-DPCCH. The feedback transmission on the HS-DPCCH is delayed by approximately 7.5 slots than the end of the corresponding data transmission on the HS-PDSCH. If a NAK is received from the UE, the Node B may transmit one of the transport blocks for retransmission, and if an ACK ' is received, one of the other transport blocks may transmit a new transmission. The Node B sends a signal on the HS-SCCH and transmits a retransmission or a new transmission on the HS-PDSCH. The signal notification indicates whether the HS-PDSCH carries a repeat transmission or a new transmission and other information. In general, Node B can send new transmissions of the transport block and, if necessary, one or more retransmissions. As shown in Figure 4, Node B can transmit multiple transport blocks in an alternating manner. Figure 5 shows the data transfer to multiple UEs in HSDPA. Node B Schedule 115949.doc -14- 1326167 The UE is used for data transmission on the HS-PDSCH in each TTI. The Node B transmits a signal for the scheduled UE on the HS-SCCH and transmits the transmission for the scheduled UE on the HS-PDSCH. Each UE that may receive data on the HS-PDSCH processes the HS-SCCH to determine whether a signal has been sent to the UE. Each scheduled UE processes the HS-PDSCH to recover the transport block that was sent to the UE. Each scheduled UE sends ACK/NAK and CQI feedback on the HS-DPCCH. A UE that is not scheduled in a given TTI may also transmit a previously transmitted ACK/NAK and a CTI of the current TTI on the HS-DPCCH. In FIG. 5, transmissions on the HS-PDSCH for instant services such as Voice over Internet Protocol (VoIP), games, and signaling on the HS-SCCH are shown in solid shades. The transmission on the HS-PDSCH for other services such as best effort and the signaling on the HS-SCCH are shown in diagonal fill. Each transmission on the HS-PDSCH is associated with a corresponding signaling on the HS-SCCH. HSDPA is designed and optimized for applications similar to downloading large amounts of data. Many simulation results for the design of HSDPA are generated based on a full buffer traffic model. This premise leads to an HSDPA design that optimizes cell output rather than optimizing delay-sensitive applications that may produce relatively small packets. Some of the consequences of the current HSDPA design are: 1. As shown in Table 2, the HS-SCCH carries a number of bits of the signal, 2. The HS-SCCH encodes and transmits in a way that is not daring. 3. The HS-PDSCH carries A relatively large transport block for some instant services > and U5949.doc 4. Each UE continuously transmits the hs-DPCCH. A large number of signallings on the HS-SCCH are used to support: (a) the elastic selection of the channelization code assigned to the HS-PDSCH, which can be changed on a transmission-by-transmission basis, (b) from the 254 possible transport block sizes Elastic selection of transport block size, (c) elastic selection of non-synchronous IR transmission and retransmission time, (elastic selection of magic redundancy version, and (e) elastic selection of modulation. All such elastic features result in A large number of additional items on the HS-SCCH. In addition, the signalling on the HS-SCCH is divided into two parts as described above to simplify the UE construction. As shown in Figures 4 and 5, the HS_pDSCH transmission is relative to the HS- SCCH transmission delays to simplify UE construction. These features are not optimal and even become larger due to HS_SCCH. HS-PDSCH can carry different sizes of transport blocks to better match The data is matched by the load. The HSDPA support range is from 137 to 27,952. The size of the transport block depends on the cargo change mechanism (for example, QPSI^16 qam) and is used for hspdsch. The number of channelization codes transmitted. The set of different round block sizes Can be used for different numbers of channelization codes. For example, when assigning a channelization code for HS-PDSCH, you can use 1〇3 ranges from ... to (7) bits to send the block size. 1 Smaller The rounding block size can utilize too much channelized code space. The spreading factor of 16 is used for HS_PDSCH because the expansion factor reduces the amount of signaling used to convey the assigned channelization set and provides sufficient data for the data. Code space granularity. This expansion factor selection results in a smaller transport block size with a smaller effective bit rate (which is rarely used for full-slave traffic). For example, 115949.doc 1326167, all have 137 to 449 bits of QPSK The transport block size has a code rate of 1/2 or less on the first transmission. For v〇Ip, the full rate frame of 12 2 兀 秒/sec (kbps) adaptive multi-rate speech contains 3 17 bits το. One typical transport block size of this full rate frame has a code rate of about 1/3 on the first transmission. This typical transport block size excess valley results in a first transmission rate ratio. Low, which can result in being used for full rate frames The line resources are more than necessary. The data transmission can be received on the HS-PDSCH for each 1; the feedback information (for example, CQJ) is continuously sent on the HS DpccH. The feedback information is improved on the lower link. The performance of data transmission is at the cost of uplink add-ons and more ambiguous UE battery consumption. The flexible scheduling for data transmission on HS_pDSCH requires that these UEs continuously monitor hs_scch and continuously on hs_DPCCH For the reasons mentioned above, the HSDpA design in Release 5 & Release 6 provides good performance similar to the application of the fully buffered traffic model, but for applications with low output and/or delay sensitive data. Less efficient. Furthermore, the HSDPA design does not consider issues associated with continuous packet connections, such as uplink add-ons and UE battery life. 1. Transmission with assigned parameters In one aspect, the Node B transmits a transmission on a shared data channel (eg, Hs DSCH and HS_PDSCH) to at least one parameter assigned to the UE prior to transmission to - UE. The Node B is not on the shared control channel (e.g., HS-SCCH) signaling the transmission for transmission to the UE on the shared data channel, which can greatly reduce the additional items. The job is to process the transmissions received from the shared data channel at 115949.doc 17 1326167. Shared data „delivery channel and physical channel.” For example, == ^ = use (4) channel can include coffee and approval (3). The shared channel can include other channels for other radio technologies. The parameters and any type of parameters are assigned to any of the assigned assignments including the following parameters

1 channelization code parameters, 2 · coding and modulation parameters, 3· HARQ or retransmission parameters, and 4. transmission time parameters.

The channelization code parameter may indicate the number of channelization codes and/or a particular channelization code that may be used to transmit to Xian. The assigned channelization codes can be any of the 16 chip channelization codes and/or other channelization codes available for the DSCH. For example, the UE may be assigned a channelization code having a spreading factor of 32 or 64, which may occupy less code space than a 16 chip channelization code. The UE may process the shared data channel only for the assigned channelization code and may ignore other channelization codes. The encoding and modulation parameters can indicate how the data is encoded and modulated. For example, the encoding and modulation parameters may indicate one or more modulation mechanisms (eg, QPSK and/or 16 QAM) available for transmission to the UE, one or more transport block sizes, one or more codes Rate and so on. The UE may process the shared data channel based on the assigned encoding and modulation parameters. 115949.doc 1326167 The HARQ parameter may indicate parameters suitable for transmission/retransmission to ue, such as whether synchronous IR is used, a sequence of redundant versions of transport blocks, the number of retransmissions of transport blocks, transport blocks Minimum time interval between consecutive transmissions, ACK/NAK feedback settings, etc. A redundant version of the transport block may be sent in a particular order (which may be a priori known by Node B and UE). For example, the first redundancy version can be transmitted in the first transmission of the transport block, the second redundancy version can be sent in the first transmission, the third redundancy version can be sent in the third transmission, and the like. The ACK/NAK feedback setting may indicate whether to send both ACK and NAK feedback, or only ACK feedback or the like. When no h-number notification is sent on the HS-SCCH, the UE cannot determine whether the following situation has caused a decoding error: (a) the transport block '(b) being sent to the UE and erroneously decoded by the ue is sent A transport block to another UE, or a transport block that is not sent to any UE. Therefore, the UE cannot know when to send the NAK for its transport block. By transmitting only ACK feedback, it is possible to avoid external signaling due to ΝΑκ generated by the transport block transmitted to other UEs. The transmission time parameter may indicate the time interval or 可 at which the transmission can be sent to the UE. For applications that periodically transmit data, the assigned time interval can be determined based on the periodicity of the data (e.g., for each 〇 or 2 〇 ms for ν 〇Ι ρ). The UE may only process the shared data channel during the assigned time interval and may enter a sleep state during other times to conserve battery power. The assigned parameters may also include other types of parameters, which may depend on the system design. For example, in a system based on 〇FD]VI, the parameters of the 115949.doc •19·1326167 can be used to indicate the transmission to the MME—or a plurality of specific subcarriers. The parameters assigned in the system supporting multiple input multiple output (MIM(R)) transmissions may indicate the number of data streams that can be sent to the certificate: one or more precoding matrices that can be used to transmit to the UE, and the like. The shared data channel can include transport channels and physical channels, such as 峨Η and HS (9) specific parameters (eg, coding parameters) can be applied to the transport channel portion & of the shared data channel, while other parameters (such as 1 change and channelization code) Parameter) can be applied to the physical channel of the shared data channel: minute. In the aspect: one or more transmission formats can be defined and assigned to one = every two transmission format can be associated with one or more specific parameters for transmission. For example, t '-transport format can be used with the following items A particular set is associated with a plurality of channelization codes, a particular modulation mechanism, a particular code rate, or a transport block size. The Node B may send the transmission based on one of the transmission formats assigned. If the UE is assigned multiple transport formats, then Node B may use any of the transport formats transmitted to the parent-transmission of the number r XX. ^UE. In general, the parameters can be used for anything related to data transfer, such as block size, code rate, modulation mechanism, HARQ parameters, time interval, and so on. - The transport format may be associated with one or more specific parameters (eg, block size and modem) and may be a convenient mechanism for communicating parameters. - Generally, the assigned parameters may be used in any wireless communication system. Any shared data channel. The assigned parameter can be poem hsdpa in order to avoid sending a signal notification on the HS-SCCH. It can be used as follows - or more. 115949.doc • 20- 1326167 The new sub-information of HS-DSCH Box format or transmission mode: 1. Do not send signal notification on HS-SCCH, 2 · — or multiple specific channelization codes can be used for transmission to ue, 3. — or multiple specific modulation mechanisms can be used for transmission, 4· One or more specific transport block sizes are available for transmission, 5. HARQ is set to a synchronous IR with a predetermined number of retransmissions and a redundant version of the predetermined sequence, and 6. A UE-specific CRC is used for Each transmission block sent on HS_pDSCH. Some parameters of these parameters can be fixed, while other parameters can be configurable. In one aspect, the channelization code and the transport block size are configurable. Parameters, and other parameters are fixed For example, the modulation mechanism can be fixed to QPSK 'the number of retransmissions can be fixed to two (five), the sequence of redundancy versions can be fixed, etc. These fixed parameters can be determined by Node B and known first. The configurable parameters can be determined at the beginning of a call and can be changed during the call. One or more transport formats can be defined for a UE. For example, the transport format can be defined by the following items: 1 .Specific channelization code for HS-PDSCH, 2·Specific modulation mechanism (eg qPSK), 3.Special transport block size, 4 ·HARQ „has two retransmissions and a predetermined sequence Redundant version of the synchronous IR, and 5 · UE-specific crc. 115949.doc 1326167 Multiple transport formats with different parameters can be defined for the UE. For example, two transport formats can be defined for two different Transport block size and same channelization code, modulation mechanism, etc. In general, the transport format can be associated with any number of parameters and any type of parameter. The parameters communicated via the signaling on the HS-SCCH can therefore be fixed Or in Configured/assigned before the transfer. In a design, all parameters communicated via the signaling on the HS_SCCH can be processed as shown in the last row of Table 2. In this design, all of these parameters are fixed or Configuration/design so that no signalling on the HS-SCCH is required. In this design, a single channelized code and two transport block sizes can be used for transmission to the ue. These can be selected based on the data needs of the call. Two transport block sizes. For example, for VoIP calls, the 353-bit transport block size can be used for !2.2 Kbps AMR_NB audio frame or ΐ2 6 audio frame] 6 i-bit transport block size available There is no voice descriptor (SID) frame in amr nb or amr_ WB. Other transport block sizes and/or different numbers of transport block sizes may also be used. In one aspect, the UE may be assigned a channelization code available for sHs_pDSCH: one of - or multiple channelization codes. In another aspect, ue can be assigned a channelization 具有 having a spreading factor greater than 16. The ue can then de-spread the received transmission with a channelization code that is shorter than the shortest channelized code length of the shared data channel. This larger spreading factor reduces the granularity in code space assignments and can improve channelization code utilization. For example, a UE with a smaller data payload size (e. g., for a read or game) can be assigned - a channelization code with a spreading factor of 32 and can then occupy half of the code space. The transmission transmitted with the (4) pass H5949.doc -22-channelization code may have a sf=16 channelization code - the transmission of the pair:: rate 'the rate is a rate with a low bit rate required by the transmission , ',, the transfer wheel is twice as high.

In the re-state, the input compensates for the higher code predetermined mode to change with time}, the channelization code (which can be coded) or the parameter assigned by the different channelized UE in different time intervals can be - Other ways are given. In the circumstance of the syllabus, the transmission of the sputum and / or some of the parameters assigned by Qiu and the establishment = can be used for the case, and the assigned wheel requires 43⁄4. The time interval of the "pass-through" can be selected based on the call game, #等, etc. Due to changes such as the data request V°P or the travel charge, each of the yueq+be paying for the clothing, the system is assigned to the same Modify the parameters assigned by the organization.

The number is uploaded π, L in the shared poor channel, and the assigned parameter can be sent to each UE via the upper layer signal or by the ";; method. For example, when the call is established, the layer 3 in the CDMA is enabled. The radio bearer uses the L Γ 3 ζ ζ fine (10) ^ (4) message or uses the radio bearer reconfiguration (4) (10) gamma (10) ρ ρ during reconfiguration to send the assigned parameters. ~ HS-DSCHi without the assigned parameters Data transmission. Estimate the signal quality it receives and send it to hs-dpcch 115949.doc -23· 1326167 CQ Node B has the data sent to the UE and downlinks the UE schedule. Node B processes the transport block based on the assigned parameters (example %, an assigned transport format). Node B is not on the café (4) wide number notification and the transport block is transmitted on HS.PDSCH Send ^ UE. The UE processes HS pds (:h based on the assigned parameters and will send the transport block to Zhu Xian. If the transport block is correctly decoded, an ACK is sent on /HS-DPCCH, and otherwise Send any information. The card also estimates the quality of the received signal and The CQI is sent along with the ack/bene on the Hs split CCH. If not received from the UE, the B&B may send-retransmit' and if the -ACK is received, one of the other transport blocks may be sent for new transmission. Node B transmits retransmissions and new transmissions without any signalling on the HS-SCCH. Figure 7 shows the transmission of data to multiple ues with assigned parameters. Section (iv) is assigned on the HS-PDSCH The parameter of the parameter is transmitted (shown in solid shade) and sent to the unassigned parameter (shown in diagonal fill). Node B sends the signal to HS-SCCHJi only to the parameter assigned by the benefit. UE (shown in diagonal padding). Node B does not send a signalling to the fairy with the assigned parameters. As indicated in Figures 5 and 7, by not signaling to the certificate with the assigned parameters, A lot of radio resources are saved. Figure 8 is a block diagram of the design of the data processor (10) and the modulator 220 at point B 11 in Figure 2. For clarity, Figure 8 shows The processing unit of one UE transmitting on one of the HS-PDSCH. The CRC generator 81 in the processor 210 generates a CRC of the transport block 115949.doc • 24- 1326167. The scrambler 812 can scramble the transport block based on the UE identifier (UE ID) of the recipient UE, CRC or both transport block and CRC. This UE ID may be a MAC ID or some other type of ID that uniquely identifies the recipient UE. A UE-specific CRC may be generated in various ways such that the CRC is The recipient UE is unique. For example, the CRC can be generated in a conventional manner, and then the CRC can be made unique to the UE. This can be achieved by performing a mutual exclusion or (XOR) operation between the computed CRC and the UE ID. In general, the UE-specific scrambling code can be executed on all or any part of a transmission and can also be performed anywhere along the transmission processing path. Encoder 8 14 encodes the scrambled block based on an encoding mechanism and provides a coded block having a selected transport block size. The controller 240 can select the transport block size based on the CQI received from the UE, the transport block size assigned to the UE, and the like. The HARQ unit 8 16 divides the coding block into a plurality of redundant versions. For each transmission, HARQ unit 81 6 determines the redundancy version to be transmitted based on the HARQ control from controller 240 and provides the selected redundant version. Channel interleaver 818 interleaves (or reorders) the code bits in the selected redundancy version. The symbol mapper 820 maps the interlaced bits to the data symbols based on a modulation mechanism selected for the UE. The modulation mechanism can be fixed (eg, fixed to QPSK) when using the parameters assigned. Within modulator 220, expander 820 expands the data symbols and provides the data chips based on a channelization code assigned to the UE. The data chips are further processed and transmitted to the UE. The controller/processor 240 can receive feedback from the UE (e.g., ACK/NAK/no signal, CQI, etc.) and can be provided 115949.doc -25 - 1326167

The solution is expanded and the de-spreading symbol is provided to the symbol...—1: In the benefit 260, the received sample of the transmission received by the despreader 910

The H A R Q control of the controller 2 combines the despread symbols of the current transmission with the de-spread symbols of the two sets of one or more previously transmitted. Within RX data processor 270, symbol demapper 92 demaps the decomposed symbols from HARQ combiner 914 based on the selected modulation mechanism. For example, symbol demapper 920 can provide a log likelihood ratio (LLR) of the code bits 该 of the despread symbols. The channel deinterleaver 922 performs deinterleaving in a manner complementary to the interleaving performed by the channel interleaver 818 of FIG. The decoder 924 decodes the output of the deinterleaver 922 based on a transport block size and provides a decoded round block. As shown in Figure 9, if Node B scrambles the trc of the transport block, CRC generator 926 generates a CRc for the decoded transport block, and descrambler 928 will receive it. CRC descrambling code. If node b scrambles the transport block, then descrambler 928 descrambles the decoded transport block and CRC generator 926 generates a CRC for the transport block of the descrambled code (Fig. Not shown in 9). In either case, the detector 93 compares the CRC generated by the local 115949.doc • 26· 1326167 with the CRC of the received or descrambled code and determines whether the transport block is correctly or incorrect based on the comparison result. Ground decoding. Generally. The descrambling code unique to the UE is performed in a manner complementary to the scrambling code unique to the UE at the Node B. The controller/processor 28 can provide various parameters for each transmission of the processing (e.g., channelization code, HARq control, modulation mechanism, transport block size, UE 1 , etc.). The UE may perform transmission for a reception based on the assigned parameters

Blind decoding. The UE can process the received transmissions for every possible hypothesis until the transport block is correctly ordered or evaluated (iv). The number of hypotheses depends on the unknown cause at the UE. For example, if two transport block sizes are available for transmission, the UE can decode the received transmission for each of the two transport block sizes. In addition, if up to two retransmissions of one round of transmission blocks can be transmitted and if the UE does not have HARQ information, then the three transmitted transmissions corresponding to the received transmission can be processed as the first transmission and the second transmission. And the third transmission. In this example, the UE can perform up to six assumptions that the two possible transport block sizes and three pass possibilities are resolved; The UE can evaluate the hypotheses that can be selected in a sequential order based on the likelihood that each hypothesis occurs. For example, if the right no m transmission is correctly decoded, the UE can process the received transmission as if it were lost, and if the previous transmission is erroneously decoded, it is treated as a "retransmission". The UE can also perform the depletion of the most probable transport block size uranium, and then perform the decontamination for the next most likely transport block size, 竺. For example, if the UE is assigned two transport block sizes and the size of the large transport block is relatively small 115949.doc • 27-1326167 The transport block size is used more frequently, then the UE can transmit the smaller The block size first performs decoding on the larger round block size before performing decoding. Figure 1 shows a process 1000 of performing unsignaled data transmission by Node B. Node B assigns at least one parameter to the UE (Block 1〇12). The at least one parameter may include at least one of the following: channelization code block size, modulation mechanism, transmission format, retransmission parameters, time interval, and the like. For example, the at least one parameter can include a plurality of transport formats (e.g., multiple transport block sizes) that can be used by the UE2. The at least one parameter can be assigned during the call setup at the beginning of the call to establish the UE's no, line bearer, assigned to change the radio bearer during reconfiguration, and the like. Node B sends at least one of the assigned parameters to U E (Block U)! 4). Thereafter, Node B processes one of the UE's passes (Block 1〇16) based on the parameter assigned by the at least one item. Node B may scramble all or part of the transmission with one of the ue identifiers. Node B transmits the transmission on a data channel for a plurality of pings for processing by the UE based on at least one of the parameters assigned (block 1 (4)). The Node B can send the transmission in an assignment to the gate interval. Node B may disable the transmission of the downlink control information/signaling corresponding to the transmission on the shared data channel. Figure 11 shows the process of performing unsignaled data reception by the UE. The UE receives at least an item parameter assigned to the sen (e.g., block 1112) during, for example, call setup, reconfiguration, and the like. The at least one parameter may include any of the parameters listed above. Thereafter, the UE receives the 115949.doc -28- 1326167=the transmission wheel_1114) of the plurality of shares, and the at least one parameter assigned to the request after the (4) transmission is processed. The received transmission (block 1116). The received transmission (or transport block). The processing performed by the UE in the plurality of data packet blocks 1116 may include different transmission formats based on :: (e.g., 'different transport block sizes):: = (four) received transmissions.

In this case, the UE may process the received transmission corresponding to different assumptions prior to the received transmission: the same number of transmissions, different transport block sizes, and the like. The processing in item A 1116 may also include determining whether the UE is the destination of the received transmission. This determination may be detected by the identifier of one of the UEs - for example, generating the crc of the received transmission, and the CRC 'received by the descrambling code by the identifier H5949.doc -29 - 1326167 and will The CRC of the descrambled code is compared with the CRC generated by the local end. This determination can also be made by descrambling the received transmission with the UE identifier. The UE may receive additional transmissions on the shared data channel and may process each additional received transmission in a manner similar to at least one parameter assigned to the UE. The UE may receive transmissions discontinuously on the shared data channel. 2* Transmission with assigned time interval

In one aspect, Node B transmits a transmission to the UE on a shared data channel (e.g., hs_dsch) in the time interval assigned to the UE prior to the transmission. Node B can be in the assigned time interval instead of in the non-

The data is sent to 所 in the assigned time interval. In this case, the UE may process the shared data channel during the assigned time interval and may go to sleep at other times. In an I sample, based on a style, a

Separate. This style can also be called discontinuous reception (DRX) style, repeat sample king, and the like. "Cut the predetermined continuous phase of N time intervals, the middle of the basin - the side is called. - The time interval may correspond to a -TTI, a sub-frame or a time unit. The pattern includes one or more specific time intervals, which are individually selected by the 1" time interval spanned by the pattern. β This is the number of N times p卩pq. (d) The choice is and is included in the case where j = begins at a specific instant (for example, starting at (4) telecommunications box) and can be repeated continuously/permanently ❶ ',., to: = can be the same or different duration / The style of length ^ assigns 3 different time interval patterns to no (4) 115949.doc 1326167 to finally distribute the fUE across all time intervals available for data transfer. It can be based on the type of call, f-requirement, system load, etc. (4) The style and specific time interval assigned to a UE. For example. The time interval assigned by ν〇ΙΡ通活 can be separated by 0 or 20 ms. Likewise, more time intervals can be assigned for potentially more data, and fewer time intervals can be assigned for potentially more UE battery power savings. The ue pattern can be fed during the call setup and sent to the UE via the upper (4) notification or some /, his method § χ. The s-UE style can also be changed during a call and sent via a reconfigured message or some other method. Figure 12 shows an example pattern of six UEs to F. In this example, the υΕ style has 12 sub-frames or TTI (given by the ❹ to 标志 mark), with the same length. Each subframe corresponds to a time interval. The patterns of UE a and c include subframes 0, 3, 6, and 9. The pattern of UE b includes subframes 2, 5, 8, and 11. The style of UE D includes subframes 1 and 4, and the style of ue E The sub-frames 4 and 7 are included, and the UE F pattern includes the sub-frames 〇, 2, 4, 6, 8' 1 0. These patterns are repeated every 24 ms and the repetition of these patterns spans 24 ms. In the example shown in Fig. 12, ue A and C are assigned channelization codes 1 ' UE B and E of the HS-PDSCH are assigned channelization code 2, and UE D and F are assigned channelization code 3. In one of the squares labeled ιχ, and using the channelization code assigned to UE X, a transmission can be sent to UE X, where xe{A, B, ‘.‘9F}. The UE may discontinuously monitor the HS-DSCH based on the assigned pattern to discover possible transmissions to the UE. The UE can operate in a connected sub-state (where the UE is only 115949.doc -31 · 1326167 intermittently active), but can quickly switch to a fully active sub-state. In one aspect, the receipt of one of the transmissions on the HS-DSCH does not trigger a change from the state of the linker. "A change from the state of the linker can be achieved, for example, via an upper layer signaling message. The UE may also transmit feedback discontinuously on the HS-DPCCH according to a discontinuous transmission (DTX) pattern, which may be selected based on the DRX pattern.

Figure 13A shows an example transmission using UE a assigned to the UE A pattern of Figure 12. In this example, the transport block is transmitted in the subframe and retransmitted in subframe 3. No transmission is sent in subframe 6. Transport block 2 is transmitted in subframe 9 and is not retransmitted. The transport block 3 is transmitted in the sub-frame 接收 received in the next pattern. In each of the assigned subframes, if no signal is sent on the hs_SCCH, UE A can blindly decode - new transmission and/or repeated transmission. FIG. 13B shows the use of ue d assigned to the style of UE D in FIG.

Example transfer. In this example, no transmission is sent to the certificate D in the subframe. The transport block 1 is transmitted in the subframe 4 and retransmitted in the sub-frame 1 of the lower-style reception. Figure 13C shows an example transmission f using the pattern f assigned to the certificate f in Figure 12. In this example, the retransmission can only be sent at least two subframes after the end of the previous transmission. No transmissions are sent to UE F in the subframe. The transport block 1 is given in the sub-frame 2, and the transmission 'because the two sub-frames of the previous transmission in the sub-frame 2 are not retransmitted in the sub-frame, but in the sub-message The retransmission in block 6 is not transmitted in the subframe 8 to the transport block 2 and is transmitted in the subframe 1G and is not transmitted again. 115949.doc -32- 1326167 Multiple UEs can be assigned the same time ... Π time interval and the same channelization code. For example, s, UE in Figure 12 Α>3 Γ诎社 ν 4, such as eight and € are deducted the same sub-frame and channel ττρ_ in - (4) the towel will be transmitted - to the post will also be - channel The code is assigned to another UE. Each -μ can detect a unique CRC to determine if the transmission is intended: Γ-1" can store the received samples at the assigned time interval for possible HARQ combining with future transmissions. Every _ welcome can be judged by

Estimating different hypotheses to attempt to recover - transmissions in a given time interval, such as: the current transmission is one of the first transmission (not HARQ combination) hypothesis; the current transmission is the second transmission (and therefore Another assumption of the combination with the past transmission; the current transmission is another assumption of the third transmission (and therefore combined with the past two transmissions), and so on. In the example shown in Figure 12, each UE is assigned one of the channelization codes of HS_PDSCH. In general, the UE can be assigned any number of channelization codes and any of the channelization codes available for the HS-PDSCH. As shown in Figure 12, the same channelization code is assigned in the -state and used for all time 35 assigned to the UE. In another aspect, different channelization codes can be assigned for different time intervals. For example, UE F may be assigned a channelization code 1 in subframe 4 to avoid collisions with ue d in the code domain in the subframe. The UE may be independently assigned a channelization code for each of the sub-frames included in the style of the ue. In one aspect, the transmission is sent to a UE in the assigned time interval while signaling is sent on the HS-SCCH. The 1; £ can process the HS-SCCH in an assigned time interval and determine if a 115949.doc -33 - 1326167 transmission on the HS-PDSCH is transmitted to the UE. If the signalling indicates that one of the UEs is transmitting, the UE may process the HS_PDSCH based on the signalling received from the HS-SCCH. Otherwise, if the signal notifies that the UE is not transmitting, the UE may return to the sleep state without processing hlpdsCH. In another aspect, the 'transmission is sent to a UE in its assigned time interval, while not transmitting a signal on ^8(:::11. As described above, in the case of the έH, the Node B can Use the parameters assigned to the UE in one assigned

The transmission of the transmission to the UEe in the time interval is also as described above, and the certificate may perform blind decoding of the HS-PDSCH in each of the assigned time intervals based on the parameters of the circumstance.

In one aspect, for example, as shown in Figure 13B, the HARQ combination is allowed during different repetitions of the pattern. In the other _ aspect, the HARQ combination is not allowed during different repetitions of the style. For example, the transmission in sub-pure U) for the first pattern repetition of Ue f in Figure 12 is not combined with the transmission in the lower-pattern weight (four) sub-frame 〇. The HARQ constraint limits all transmissions of the transport block to a repetition of the pattern, causing the material to transmit new transmissions and retransmissions in different repetitions of the pattern. Since the UE can use the start of the pattern as the HARQ^-synchronization mechanism, the harq constraint can reduce the decoding complexity! The raw block that is not correctly decoded at the end of one of the singular styles can be below the style. A new transmission is transmitted in the repetition. Figure 14 shows that the process of data transmission with the assigned time interval is performed by point B, and the time interval of the data transmission that can be used by the UE is sent to the UE. From the individually selected time interval (block Μ. The assigned phase interval can be used - data 115949.doc • 34 - 1326167 transport block) to the UE for transmission and retransmission. The assigned time interval is assigned to other UEs such that a transmission can be sent to any one of the UEs assigned the time interval in a given time interval. The Node B is in a time interval assigned to the UE The _transmission (block 1414) is sent to the UE over a plurality of ue-shared data channels (e.g., HS-DSCH and HS-PDSCH). Figure 15 shows a process 1500 of performing data reception with an assigned time interval by a UE. UE receives one can An assignment of time intervals for data transmission to the UE, which may be given by a pattern of individually selected time intervals (block 1512). The UE is in a multiplicity of time intervals assigned to the UE and determined based on the pattern. A transport path is received on the data path shared by the UEs (block 1514). The UE processes the received transmission and attempts to recover the data transmitted in the transmission (block 1516). For example, the 1; A plurality of transmission formats usable for the time interval to process the received transmission, to despread the received transmission ', etc., with a channelization code for the assigned time interval. The UE may also, for example, borrow De-scrambling the data and/or a received CRC with one of the ue identifiers to determine whether the UE recovered from the received transmission is destined for the UE. The UE may be at the assigned time interval. The shared data channel is monitored during the period and the monitoring of the shared data channel can be skipped during the remaining time. 3. Transmission with assigned parameters and time intervals In general, the Node B can send transmissions to the UE in various ways.

In configuration 2, the Node B may send a transmission to the UE and only use the assigned one in the subframe assigned to the UE.

parameter. Node B does not send any signaling on the HS-SCCH. In this configuration, the UE can process the HS-PDSCH only in the assigned subframes based on the assigned parameters and can go to sleep in other subframes. In configuration 3, point B can send a transmission to ue in any subframe using the assigned parameters and will not signal. The UE may process the HS-PDSCH in each subframe based on the assigned parameters. In Configuration 4, Node B can send a transmission to the UE only in the assigned subframe. Node B can use the assigned parameters and will then not signal the notification. Node B may also use non-assigned parameters and will then signal on the hs-SCCH. In configuration 5, node b can send the transmission to the UE using the assigned parameters in the assigned subframe and can use any parameters at 115949.doc • 36 · 1326167 other subframes to send transmissions in the configuration wipe Node b may signal on inter-exchange on the HS-SCCH: (a) when transmitting in a non-assigned subframe as indicated in Table 3, or (b) when using a non-assigned parameter. In configuration 6, Node B can transmit transmissions in any subframe using the assigned or non-assigned parameters and will signal when non-assigned parameters are used. Configurations 4, 5, and 6 support the assigned and non-assigned parameters for transmission to the UE. The non-assigned parameters are limited to the assigned sub-frame in configuration 4, to non-assigned sub-frames in configuration 5, and are not restricted in configuration 6 for any sub-frames. Configurations 4, 5, and 6 allow transmissions to be sent using the existing HS-DSCH format (signaling on the HS-SCCH) and the new Hs·DSCH format (not signaling on the HS-SCCH). In some configurations (such as configurations 4 and 6 in Table 3), ^^ can receive transmissions with or without signaling on the Hs_SCCH. In this case, the ue can process the HS-SCCH to determine if a signal has been sent to the UE. If a signal is received on the HS-SCCH, the UE can process the HS-PDSCH based on the received number notification. If the k-number notification is not received on the HS-SCCH, the UE may process the hS_PDSCH based on the assigned parameters. When the § § notification is not received, ue may perform blind decoding on the transmission received on the HS_PDSCH as described above. Figure 16 shows a process 1600 for performing data transmission with and without signaling by Lange B. The Node B sends an assignment of at least one parameter to the UE (block 1612) during, for example, call setup or reconfiguration. Node B transmits a transmission to the UE based on at least one parameter selected for transmission (block 1614). Node B can transmit transmissions on a shared data channel. If the at least one selected 115949.doc • 37-1326167 疋 parameter is not among the at least one assigned parameter, the Node B sends a signal (block i6i6) containing the at least one selected parameter to the UE. If the:-item selection parameter is among the at least one assigned parameter, then P-point B does not send a signal notification (block μη) for transmission. The Node B may select at least one parameter for each transmission to the ue and may signal a transmission only for transmissions that are not transmitted among the parameters of the at least one assigned parameter. For configurations 4 and 5 in Table 3, the section only uses the parameters assigned by the "Xuan to J" term for the transmissions sent during the interval = interval. For configuration 6, the Node B can use the assigned or non-assigned parameters for each transmission to the UE. Figure 17 shows an L-lane 1700 performed by the UE with and without signaled data reception. The UE receives at least during, for example, call setup or reconfiguration

Assignment of the item parameters (block 1712) The UE signals the decoding on a control channel (e.g., hs_SCCH) (block 1714). If the signal is successfully decoded, the UE is derived based on the signal notification. At least one parameter is processed - the data channel (eg, *, 〇 〇 followed by Hs pDscH) on the second transmission (block 1716). If the signal is not successfully decoded, the ue is assigned based on at least one item a parameter to process the transmission (block PM). For block 1718, the UE may first process the transmission based on a first set of at least one assigned parameter (eg, a first transmission format), and if If the transmission is not successfully decoded, the transport is processed based on a second set of at least one assigned parameter (eg, a second transport format). For HARQ, the UE may first use the transmission as a new one. The transmission is processed; and if the transmission is not successfully decoded, the transmission is treated as a retransmission to U5949.doc • 38·. When processed as a retransmission, the transmission can be combined with Stored transfer combination to get one Combining the transmission and then processing the combined transmission based on parameters of at least the item. If the transmission is not successfully decoded, the UE may also store the transmission for future combinations. The techniques described herein may be used effectively Support for instant services (eg, IP, video, games, etc.) and bursting services. These technologies allow shared beacon channels to effectively support the frequent transmission of smaller packets on the downlink and other bursts of data that can be sent. Services. These technologies are especially advantageous for asymmetric applications where more data is sent on the downlink than on the uplink. These asymmetric applications may include: games, instant streaming video, instant streaming audio. Interactive multimedia queries, broadcasts, etc. These technologies can increase system capacity and thus improve the wait time for instant services. The lower latency on the downlink can be: (a) improved user experience (which can be used for total round trips) Delay sensitive), and/or (b) allow more latency on the uplink with a given round trip delay (which can potentially increase the uplink key These technologies may also allow network operators to more smoothly mix instant services (such as 'VoIP') with other services. As mentioned above, these technologies can be used for HSDPA. New HSs with assigned parameters The -DSCH format does not require signaling on the associated HS-SCCH and is backward compatible with HSDPA Release 5. These new HS-DSCH formats: (a) can only be used in assigned subframes to allow ue for DRX Operation 'or (b) is used in any subframe to provide resiliency.
