Description

Transmission method, base station and mobile station implementing the method

The present invention relates to a wireless cellular communication network, and more particularly to a transmission method, a base station, and a mobile station implementing the method.

The term "wireless cellular communication network" as used herein refers to any type of radio (or wireless) cellular network, in particular, "Global System for Mobile Communications (GSM)", "Universal Mobile Telecommunications System (UMTS) ), CDMA, CDMA 2000 (3GPP2), "Frequency Division Multiplexing (FDD)", "Time Division Multiplex (TDD)", WiMAX, Evolved UTRAN (also known as "Long Term Evolution" or LTE).

The term "mobile station" as used herein refers to any type of fixed or mobile (or portable) communication terminal capable of exchanging data with a radio communication network on a radio communication link (eg, for example, portable) , pocket type, hand-held type, including computer type, or vehicle type mobile device). Therefore, the mobile station can be especially a mobile phone device (also known as a "cellular phone" or "smart phone"), a laptop computer equipped with a radio communication interface or a personal digital assistant (PDA), equipped with A server with a radio communication interface or a local router, a high frequency radio receiver, or a terrestrial or satellite television receiver. In UMTS and LTE systems, the mobile station is called a "user equipment (UE)".

In a typical cellular wireless communication system, a mobile station communicates with one or more core networks via a radio access network (RAN). Radio storage The fetch network provides radio coverage across a geographic area divided into a plurality of cellular regions, where each cell region is served by a radio access node, such as a base station. The cell is a geographical area where the radio coverage is provided by the base station equipment at the base station. The radio access node and the mobile station are adapted to communicate via the empty interfacing plane when the mobile station is within the radio coverage of the cell served by the radio access node or base station.

The radio access network infrastructure of a cellular wireless communication system typically includes a base station dispersed throughout a covered jurisdiction to communicate with a mobile station located in the area or cell in which it is served.

In the present description, the invention will be described, inter alia, and without limitation, in the application of a third generation communication network of the UMTS type. In this system, the present invention is applicable to the so-called "High Speed Downlink Packet Access (HSDPA)" feature currently specified by the 3rd Generation Partnership Project (3GPP), the overall description of which can be found in 3GPP 25.308 The technical specification is published by 3GPP in June 2011 as "UTRA High Speed Downlink Packet Access (HSDPA); Overall Description; Stage 2 (Release 10)", version 10.5.0.

In the third-generation radio communication network of the UMTS type, there is also a high-speed data transmission function in the uplink direction (from the user equipment to the UMTS radio access network), which is called "High Speed Uplink Packet Access (HSUPA)". (The HSUPA feature is also referred to as "FDD Enhanced Winding" in 3GPP terminology, or "Professional Exclusive Channel (E-DCH)" according to the name of the transport communication. HSUPA is based on the so-called "E-DCH", a new type of transport channel that also supports HARQ-type hybrid data retransmission request procedures, tuning Appropriate coding and modulation mechanism, and base station scheduling for uplink data transmission.

Figure 1 shows the architecture of one such UMTS network. The switch 10 of the mobile service belonging to the core network (CN) is linked to one or more fixed networks 11 on the one hand and, on the other hand, to the command device 12 or "radio" via the so-called lu interface. Network Controller (RNC). Each RNC 12 is linked to one or more base stations 13 via a so-called lub interface. The base station 13 dispersed in the area of responsibility covered by the network can communicate with the mobile terminals 14, 14a, and 14b called "User Equipment (UE)" by radio. Base stations can be clustered together to form a node called "Node B." Some RNCs 12 can further communicate with one another via the so-called lur interface. The RNC and the base station form an access network called "UMTS Terrestrial Radio Access Network (UTRAN)".

The UTRAN contains elements of layers 1 and 2 of the ISO model and is intended to provide the required links on the radio interface (referred to as Uu) and to control the radio resources belonging to layer 3 ("Radio Resource Control (RRC)") Phase 15A, as in 3GPP TS 25.301 Technical Specification "Radio Interface Protocol Architecture", Release 10.0.0, 10th Edition, published by 3GPP in March 2011. From a higher level point of view, UTRAN only acts as a relay between the UE and the CN.

HSDPA allows high-speed downlink data transmission with respect to a group of mobile stations (UEs) in a coverage area of a base station, that is, from a base station to a mobile station. It relies on time sharing and code sharing for high-throughput downlink transmission channels: "High-speed Link Sharing Channel (HS-DSCH)", which is multiplexed on the physical channel "High-speed Physical Downlink Sharing Channel (HS-PDSCH)" .

UMTS allows time division multiplexing (TDD) and frequency division multiplexing (FDD) modes. In FDD mode, the characteristics of this channel are: (i) 2 ms transmission time interval (TTI) corresponding to 3 time slots of 666 μs; (ii) "Hybrid Automatic Repeat Request" (HARQ) type of mixed data. Retransmission request; and (iii) adaptive coding and modulation mechanisms.

For HSDPA, at the access network level, a specific sub-layer of the Media Access Control Protocol, "Media Access Control High Speed" (MAC-hs), is localized in the base station. This layer receives information originating from the so-called MAC-d sublayer (for which part is localized in the radio network controller RNC to which the base station is attached). Therefore, configuration matters to provide the best throughput on the HS-DSCH. For the same reason, the HS-PDSCH uses a relatively low spreading factor equal to 16. Up to 15 HS-PDSCH channels can be established using orthogonal "channelized" codes for a given cell and for a given mix. Details regarding media access control can be found in the technical specification TS 25.321, 10th edition, version 10.4.0, published by 3GPP in September 2011.

For the HS-DSCH channel, one or more specific shared entity control channels called "High Speed Sharing Control Channel (HS-SCCH)" must be provided. The originating information carried by the HS-SCCH identifies the destination terminal of the block transmitted on the HS-PDSCH and provides a certain number of indications useful to receive the blocks to the destination terminal: - transport format and resource indicator (TFRI), providing information on the format of the dynamic portion of the HS-DSCH channel, especially for the modulation scheme used, and the assigned physical resources ("channelized" code); - Information about the HARQ Agreement, especially the redundancy version, the HARQ program identifier, and the indicators for the new data block.

The feed information is additionally sent back by the terminal, especially for the confirmation of the HARQ agreement, and the useful measurement is adapted for the link. This information is transmitted by a dedicated uplink resource on a channel called the High Speed Dedicated Entity Control Channel (HS-DPCCH). Link adaptation makes it possible to modify the shaping format of the material to be transmitted as a function of the quality of the radio link. For this purpose, the terminal periodically sends back a shaping request for the interference-to-interference ratio (referred to as "channel quality indicator (CQI)") based on the downlink. The parameter CQI is encoded on 30 levels, and the interval between the two stages corresponds to an interval of 1 dB between the signal to interference ratio.

In addition, each terminal can provide information about the receiving capabilities of the base station (which the terminal finds itself within the radio coverage of the base station) via the RNC. The terminal therefore in particular indicates to the base station: - whether it supports the two modulations provided in the system, namely "Quadrature Phase Shift Keying (QPSK)" modulation and "16 Quadrature Amplitude Modulation (16-QAM) Modulation, or otherwise only one of these two; - whether its memory allows it to receive data at every TTI, or otherwise only every n TTIs, where n is an integer; - whether its memory allows it Implement all possible modes of the HARQ protocol (repeated mode, full or partial incremental redundancy mode), or otherwise only some of them.

When the HS-DSCH and HS-SCCH are set, the radio network controller ("Control RNC (CRNC)") that supervises the base station assigns the corresponding code resources for each cell to it. For example, provisions can be made to target HS- The SCCH channel retains a list of L = 16 codes with a spreading factor of 128.

At each TTI, these resources are spread among the various users who will transmit the data to them. To do so, the resource allocation is performed by the MAC-hs sub-layer of the base station being considered.

In a UMTS type network, random access follows the procedure defined in 3GPP Technical Specification TS 25.214, Version 10.4.0, 10th Edition, Chapter 6 published by 3GPP in September 2011. According to this procedure, the UE wishing to initiate communication or transmit information to the UTRAN in idle mode selects a pre-signature in a pool of available signatures for random access. The UE then uses the selected signature to generate the preamble and transmits the preamble on a random access channel (RACH) transport channel (mapped to the physical channel PRACH (physical random access channel)). The UE then waits for a response from the UTRAN transmitted by the Node B on the Acquired Channel (AICH) physical channel with an Acknowledgement (AI) or Enhanced Acquisition Indicator (EAI) form.

For HSUPA, at the MAC level, a new MAC termination point, MAC-e, has been introduced in the UTRAN architecture, and especially at the base station level. This architecture is described in the 3GPP TS 25.319 technical specification, "Enhanced uplink; Overall Description; Stage 2", version 11.1.0, published by 3GPP in September 2011.

Two modes of operation have been defined for the user equipment: idle mode and radio resource control (RRC) connection mode. In the RRC connected mode, the UE can operate in a number of liaison states with the UTRAN, which is managed by a radio resource management protocol implemented in the RNC and the UE (see by 3GPP) Technical specification 3G TS 25.331, version 10.5.0) published in September 2011. A distinction is made between the common RRC (which is Cell_FACH, Cell_PCH, and URA_PCH) and the exclusive RRC state (Cell_DCH) on the other hand. The Cell_DCH state is one of the states within the RRC connected mode in which the user equipment can transmit and receive high data throughput. In this state, the user equipment and Node B maintain physical layer synchronization in the downlink and uplink. The HSDPA feature can operate in the Cell_DCH state, but can also operate in other states such as Cell_FACH in Release 7. The mode and state of the UE in WCDMA is defined in the above specification 3GPP TS 25.331.

The Winding High Speed Dedicated Physical Control Channel (HS-DPCCH) is important to support high efficiency downlink transmission on high speed channels. In the absence of channel quality information (CQI) and downlink ACK/NACK information carried over HS-DPCCH, blind retransmissions on HSDPA result in significant loss of HSDPA throughput and extremely inefficient use of HSDPA resources.

As defined in the 8th edition of the specification, the transmission of the HS-DPCCH in the Cell_FACH state is triggered by the uplink data transmission, that is, it may be if and when the UE has the information to be transmitted on the E-DCH channel. occur. Figure 2 shows a typical procedure for transmission on the HS-DPCCH channel. After receiving the HS-DSCH packet, the packet goes up to the higher layer, where an acknowledgment at the higher layer is triggered, thereby generating a uplink transmission. The UE then goes through a so-called "pre-stage" to obtain E-DCH resources, which is followed by a so-called "conflict resolution phase". Conflict resolution More than one UE attempts to access the network using the same resources (ie, using the same pre-signature), which results in more than one UE using the same common E-DCH resource. As shown in Figure 2, there is a delay between the UE receiving the first HS-DSCH packet and transmitting its first HS-DPCCH packet.

The so-called "independent HS-DPCCH" is a new feature that is currently being defined by 3GPP within the framework of the development of the 11th edition of the specification, where transmission occurs on the HS-DPCCH channel without ongoing E-DCH transmission. In other words, this new feature will allow independent HS-DPCCH channels to be established based on the case of data transmission in non-winding. Based on the current defined state of this feature, the independent HS-DPCCH transmission will be triggered by the HS-SCCH order.

Compared with the case where there is a delay in obtaining CQI feedback information after transmitting some data on the HS-DSCH channel, if CQI feedback information is available in all HS-DSCH transmissions in the Cell_FACH state, significant Gain. In a radio access network adapted to use HS-SCCH commands to trigger independent HS-DPCCH transmissions, the HS-SCCH order can be used to trigger HS-DPCCH transmissions prior to any HS-DSCH transmission.

To achieve this, Node B can be adapted to delay each HS-DSCH transmission until it has triggered and obtained a CQI report (or Node B can be adapted to try to predict the arrival of each HS-DSCH packet and trigger a CQI report early) ).

For a Node B that is adapted to delay each HS-DSCH transmission so that it can trigger HS-DPCCH and obtain some CQI reports, the total delay will include Node B sends the HS-SCCH order, the UE goes through the pre- and collision resolution phases, and Node B gets the X CQI reports, as shown in Figure 3. The number X of CQI reports may be equal to one (corresponding to one CQI report), or greater than one, in which case several CQI reports may be processed to obtain an average. The simulation has shown that the pre- and collision resolution phases introduce delays of up to 50 ms. It should also be noted that there may be mutual HS-DSCH packets for more than one UE and therefore the Node B may not be able to schedule HS-DSCH transmission to a UE immediately after obtaining the CQI. For example, the Node B may decide to schedule the packet to be better. Another UE of the CQI, and when the Node B considers the scheduled packet to the unscheduled UE in the near future, the unscheduled UE may need to go through the pre- and collision resolution phases again (ie, the delay may be aggravated) ). In addition, when the Node B wishes to transmit the HS-DSCH, there may be no HS-SCCH resources, which may increase the delay.

It is therefore desirable to provide a way to implement this independent HS-DPCCH feature that allows this feature to be utilized efficiently, especially with less delay.

Indeed, for Node Bs that implement HS-DSCH transmission delays to wait for CQI to report feedback information (to minimize the overhead management burden), the delay in obtaining the HS-DPCCH transmission uplink resources should be minimized.

It has been proposed and considered to skip the pre-stage by including the index to the common resource within the HS-SCCH order itself. This theoretically removes both the pre- and conflict resolution phases. However, the UE still has to synchronize and achieve the correct transmission power to transmit the HS-DPCCH. In addition, it can be argued that skipping the pre-stage does not significantly reduce the pre-delay, but there is a cost introduced at Node B to detect the additional complexity of the DPCCH. Referring to skipping the pre-program The proposal thus has the above disadvantages.

There is provided an improved transmission method in which the PRACH pre-power ramp-up procedure is reused to obtain the first common uplink resource of the HS-DPCCH transmission. According to this transmission method, the index to the common resource is included in the HS-SCCH order to the UE, and the UE experiences a pre-stage corresponding to that common resource index. In this case, other UEs may randomly select the same preamble as the one of the corresponding HS-SCCH. The UE to which the HS-SCCH command is sent will transmit the HS-DPCCH after completing the pre-stage, while other UEs using the same pre-signature will not be on the HS-DPCCH channel (but only on the E-DCH channel) ) Transfer. The proposed method therefore also includes a collision resolution phase during which the UE receiving the command differs from the other UE that did not receive the command but uses the same resource index by the fact that the UE transmits different channelization codes. . Therefore, Node B, in response to the detection of the HS-DPCCH transmission, can resolve the contention by detecting the HS-DPCCH and the E-DCH in parallel, and still transmitting the E-RNTI with the corresponding E-RNTI (ie, being commanded to transmit the HS- E-AGCH of the UE of DPCCH. This method does not avoid conflict resolution but allows the UE to transmit the HS-DPCCH after the pre-stage.

According to an embodiment, the HS-SCCH order includes an indicator of the pre-signature that the UE can use for its initial access. It should be noted that the pre-signature is not required to be from a reserved group, ie no pre-signature is required to be retained in accordance with the proposed method. Also, as noted above, the UE does not skip the pre-stage. Proposed The method further includes a conflict resolution phase during which the UE receives the different channelization codes to distinguish between the UE receiving the command and the command that does not receive the command but transmits the same pre-signature. UE. According to this embodiment, only the UE receiving the command transmits the HS-DPCCH (using the channelization code associated with the HS-DPCCH transmission) and the other UE not receiving the command transmits the E-DCH (using the channel associated with the E-DCH) Code). This aspect recognizes that the HS-DPCCH uses a different channelization code than those used in the physical channels in the E-DCH (E-DPDCH and E-DPCCH). The Node B can thus distinguish the UE by detecting the HS-DPCCH.

Alternatively, during the conflict resolution phase, the UE receiving the command may transmit the E-DCH as well as the HS-DPCCH. However, E-DCH suffers from interference from E-DCH transmissions from other (unintentional) UEs using the same resources.

For a UE that does not receive a command, the Node B can confirm its authorization for transmission on the selected E-DCH resource by using the legacy procedure of transmitting the E-AGCH with a single targeted UE ID. Such a UE ID may be, for example, an E-RNTI, that is, an E-DCH radio network temporary identifier, which is allocated by the Node B in response to a UE requesting to establish an E-DCH channel. It may also be an H-RNTI, that is, an HS-DSCH radio network transaction identifier, which is allocated by the controlling RNC in response to a UE requesting to establish an HS-DSCH channel. This aspect recognizes that in some scenarios it may not be possible to get the E-RNTI at Node B, so the UE is adapted in this case to be able to recognize that the Node B may send different types of IDs (from E-RNTI) to end the contention resolution. More than one of these other UEs is used for their access requests to the network In the case of the same pre-signature, this E-AGCH also resolves the conflicts between those other UEs and stops their use of all of the common resources in addition to one. Alternatively, the Node B may acknowledge the transmission of one of the other UEs by transmitting an E-AGCH having the ID of that UE (ie, the ID of the UE that did not receive the command). This allows simultaneous reception of both HS-DPCCH and E-DCH from different UEs.

According to an embodiment, the pre-signature indicator includes an index of a common E-DCH resource index associated with the intended pre-signature by a one-to-one mapping.

According to another embodiment, the Node B indicates the E-DCH resource index in an Extended Acquisition Indicator (EAI) transmitted in response to a preamble on an Acquisition Indicator Channel (AICH) that is different from the one included in the HS-SCCH order. This aspect recognizes that the UE needs to transmit the uplink DPCCH (boot) for channel estimation and synchronization purposes. Here, the UE receiving the HS-SCCH order will use the resource index referred to in that command, while the other UEs will follow the legacy procedure and use different resource indexes through the EAI uploaded on the AICH.

According to a further embodiment, the UE receiving the command and starting transmission on the HS-DPCCH sets a timer when it starts transmitting on the HS-DPCCH after the pre-stage. If the timer expires and the UE has not received the E-AGCH (ie, no E-AGCH), it stops the HS-DPCCH transmission and releases the common resource.

According to yet another embodiment, if the UE has an existing E-DCH transmission and receives an HS-SCCH order to trigger an HS-DPCCH transmission, it may request a common using the same pre-signature received in the HS-SCCH order. E-DCH resources (to transmit UL E-DCH data and HS-DPCCH). In this case, the UE and Node B may use the HS-DPCCH-based contention resolution procedure proposed herein instead of the legacy E-DCH-based contention resolution procedure. However, the E-DCH resource index referred to by the HS-SCCH order, and thus used by the UE, can be used for UL E-DCH and HS-DPCCH transmission. This basically enables Node B to change the UE Common Resource Index. Second, in this case, the UE may not send the E-RNTI in the Mac-I header because the contention has been resolved.

An example of the use of the method proposed herein is provided below and is illustrated in the accompanying drawings.

Figure 4 illustrates an exemplary scenario as described below in accordance with the proposed method, in which three UEs perform access to Node B. Figure 5 is a diagram showing the channels transmitted by the three UEs (UE1, UE2, and UE3) in the conflict resolution phase according to the scenario shown in Figure 4.

Node B 4 on Figure 4 is part of the UMTS radio access network and is connected to nodes of the network (such as other Node Bs and RNCs), which are not shown for simplicity of illustration. The three UEs shown in Figure 4 have an established RRC connection with Node B 4 and are therefore connected to this Node B.

Node B 4 sends an HS-SCCH order to UE 1 to trigger independent HS-DPCCH feedback from UE 1. The HS-SCCH order sent by the Node B includes a common E-DCH resource index 5, so that the UE 1 uses the phase The code of the common E-DCH resource referred to in index 5. Each common E-DCH resource corresponds to a specific pre-signature. UE 1 therefore knows which pre-signature to use (in this example, the pre-signature number 5). Upon receiving the HS-SCCH order, the UE 1 begins the pre-stage by transmitting the pre-signature number 5 to determine the power level required to transmit the uplink packet.

At the same time, UE 2 and UE 3, which are not triggered by HS-DPCCH transmission, decide to access the network to obtain E-DCH resources, and follow the old random access procedure, just before the pre-signature 5 is used for its use. Set the stage, thus causing a conflict. Node B 4 receives the pre-signature 5 and sends a positive response with the EAI pointing to the resource index 8 on the AICH. The UE then uses the following resource indices, respectively: UE 1 uses Resource Index 5 (according to the HS-SCCH order); UE 2 uses Resource Index 8; and UE 3 uses Resource Index 8.

UE 2 and UE 3 transmit E-DCH packets (this contains their individual E-RNTIs). UE 1 transmits the HS-DPCCH, which uses the different channelization codes used by the E-DCH to transport the physical channels (E-DPCCH and E-DPDCH), as shown in Figure 5. Since only one UE (ie, UE 1 for the UE) uses the mix code indicated by the common resource index 5 to transmit the HS-DPCCH, and other UEs use the other common resource index 8 to transmit only the E-DCH, the Node B 4 may The HS-DPCCH transmission is detected and adapted for it. Upon detecting the HS-DPCCH transmission, Node B 4 transmits the E-AGCH with the E-RNTI of UE 1 to end the collision resolution phase.

Another example of the use of the proposed method is described below: it is also assumed here that the three UEs shown in Figure 4 have been built with Node B 4 Establish an RRC link and therefore connect to this Node B. Node B 4 sends the following command to trigger HS-DPCCH transmission: HS-SCCH order with common resource index 7 to UE 1, and HS-SCCH order with common resource index 9 to UE 2. It is assumed that the common resource index 7 corresponds to the pre-signature 7 and the mix code 7, and the common resource index 9 corresponds to the pre-signature 9 and the mix code 9, and the UE 1 and the UE 2 respectively pre-sign 7 and 9 start pre-position stage. At the same time, the UE 3 decides to access the network and randomly selects the pre-signature 9 and thus collides with the UE 2. After the pre-stage, the following are transmitted in the conflict resolution phase: (by UE 1) transmitting HS-DPCCH on the mix code 7, and on the mix code 9 (by UE 2) HS-DPCCH and (by UE 3) ) E-DCH.

Since the Node B expects the UE 1 to use the common resource 7 to transmit the HS-DPCCH (i.e., on the mix code 7), the Node B 4 can infer that the HS-DPCCH transmission using the common resource 7 is from the UE 1. Likewise, Node B 4 expects UE 2 to use the common resource 9 to transmit the HS-DPCCH (i.e., on the mix code 9). However, at this time, the Node B 4 detects the HS-DPCCH signal transmitted using this resource and also has the E-DCH signal. The Node B therefore knows that only the UE (i.e. UE 2) will use this common resource to transmit the HS-DPCCH, which transmits the E-AGCH with the E-RNTI of UE 2 to end the collision resolution phase.

In both examples, and other proposed procedures, the UE receiving the HS-SCCH order can transmit the HS-DPCCH with reduced delay.
