In this application.

Technical field

The present invention relates to the field of communications technologies, and in particular, to a high speed dedicated physical control channel (HS-DPCCH) uplink feedback method and user equipment. Background technique

With this new feature, the UE can receive the downlink data carried by the base station (NodeB) through the High Speed Downlink Shared Channel (HS-DSCH) in the CELL-FACH state and the CELL-PCH state.

However, after receiving the downlink data carried by the HS-DSCH in the CELL-FACH state, the CELL-PCH state, and the URA-PCH state, the UE cannot report the downlink number carried by the HS-DSCH.

The details are described below separately.

Referring to FIG. 1, FIG. 1 is a schematic flowchart of an HS-DPCCH uplink feedback method according to an embodiment of the present invention.

101. The UE receives the indication information that is sent by the NodeB by using the downlink physical channel, where the indication information includes at least a radio network temporary identifier (eg, an H-RNTI) of the UE, and resource information of the random access. The UE is in a CELL-FACH state or a CELL-PCH state or a URA-PCH state. As an optional implementation manner, the UE in the CELL-FACH state or the CELL-PCH state or the URA-PCH state has no uplink data transmission. Of course, it is in the CELL-FACH state or the implementation of the embodiment.

For example, in the embodiment of the present invention, the downlink physical channel may include, but is not limited to, an Acquisition Indicator Channel (AICH), a High Speed Shared Control Channel (HS-SCCH), and an E-DCH absolute authorization. Channel (E-DCH Absolute Grant Channel, E-AGCH), E-DCH Relative Grant Channel (E-RGCH), Fragmented Dedicated Physical Channel (F-DPCH). The embodiments of the present invention will not be repeated in the following.

102. The UE initiates random access to the NodeB by using the foregoing resource information, and detects feedback information that is sent by the NodeB through the downlink physical channel to indicate whether the random access of the UE is successful.

103. If the foregoing feedback information indicates that the random access of the UE is successful, the UE sends the power control information to the NodeB through the DPCCH, and reports the HS-DPCCH according to the timing relationship of the HS-DPCCH and the HS-PDSCH. The feedback information of the downlink data carried by the HS-DSCH and/or the CQI of the downlink channel measured by the UE are sent to the NodeB.

In the embodiment of the present invention, the feedback information of the downlink data carried by the HS-DSCH is the acknowledgement information ACK or the non-acknowledgement information NACK. When the UE can correctly receive the downlink data carried by the HS-DSCH, it reports "ACK"; when the UE cannot correctly receive the downlink data carried by the HS-DSCH, then "^' 'NAC :".

In the embodiment of the present invention, the UE reports the power control information to the NodeB through the DPCCH, so that the NodeB can start the power control.

In an actual application, the UE may send the power control information to the NodeB through the DPCCH for a period of time, and then report the HS-DSCH to the HS-DSCH according to the timing relationship of the HS-DPCCH and the HS-PDSCH. Feedback information and/or UE measurement of downlink data The CQI of the downlink channel is sent to the NodeB. The time period may be configured by the network side or by a pre-agreed manner of the network side and the UE.

In the embodiment of the present invention, the resource information refers to resource information required when the UE initiates random access, and the resource information may be a signature index, an resource index, and a physical random access channel (PhysicalRandom). Access Channel, PRACH) One or more of channel information and access slot information.

For example, the foregoing resource information may include a reserved signature index for performing independent HS-DPCCH feedback; or the resource information may include a signature index and a resource index for performing independent HS-DPCCH feedback, and correspondingly, the UE adopts After the signature initiates the random access and obtains the acknowledgment feedback from the NodeB, the HS-DPCCH feedback report may be performed by using the resource corresponding to the resource index. Correspondingly, the resource used by the UE to transmit the power control information, and the feedback information of the downlink data carried by the HS-DSCH and/or the resource used by the CQI of the downlink channel measured by the UE may be resources indicated by the downlink physical channel. Or the reserved resource corresponding to the signature on the downlink physical channel (such as the High Speed Shared Control Channel (HS-SCCH)). The reserved resource can be defined in the SIB or adopted in a manner that is pre-constrained with the network side.

For example, the foregoing resource information may include PRACH channel information and a signature index for the UE to initiate random access to obtain HS-DPCCH feedback; or the resource information includes a UE for initiating random access to obtain HS-DPCCH feedback. Enter slot information and signature index.

For a better understanding of the HS-DPCCH uplink feedback method provided by the embodiment of the present invention, the following is described by way of a specific embodiment. In the following specific embodiments, the UE is in the CELL-FACH state, and there is no uplink data transmission. When the UE is in the CELL-PCH state or the URA-PCH state, and there is no uplink data transmission or uplink data transmission, the embodiment is not used. The process is similar to the process of the following embodiment, and the embodiment of the present invention is not repeated.

An embodiment (reserved signature index scheme) In this embodiment, the Signature sequence is repeated 16 times as a preamble in the PRACH transmission, and the NodeB can distinguish the random access type of the UE according to the signature selected by the UE for independent (stand alone) HS-DPCCH feedback or for sending. Upstream data. In order to enable the NodeB to distinguish the random access type of the UE for independent HS-DPCCH feedback or uplink data, the signature may be further divided, and several signatures are reserved for indicating the scenario of performing independent HS-DPCCH feedback (ie, UE). The random signature is initiated by using the reserved signature, and the base station can know that the UE applies for resources in order to send independent HS-DPCCH feedback according to the analysis of the preamble in the PRACH. The reserved signature index can be broadcast to the UE through the system broadcast message, or the default configuration mode.

The solution of the first embodiment is as follows:

The UE in the CELL_FACH state needs to perform HS-DPCCH uplink feedback, and there is no uplink data transmission:

The UE receives the indication information that is sent by the NodeB through the downlink physical channel, and the indication information includes at least the H-RNTI of the UE, and the signature index; further the indication information may further include a resource index;

In the first embodiment, the indication index included in the indication information is reserved, and is used to indicate a scenario in which independent HS-DPCCH feedback is performed.

2. After receiving the indication information sent by the downlink physical channel, the UE initiates a random access process by using the signature of the indication information, and detects feedback information that is sent by the NodeB through the downlink physical channel to indicate whether the random access of the UE is successful.

In the random access process, because the network side specifies the signature adopted by the UE, the UE can be no longer limited to the current access slot selection mode, and random access can be initiated in any adjacent access slot.

After the NodeB detects the signature of the random access procedure, the NodeB replies with feedback information in the downlink physical channel (such as AICH/E-RGCH/E-AGCH, and the AICH channel is used as an example). Whether the UE random access is successful. 4. After detecting the success of the random access, the UE sends the power control information to the NodeB through the DPCCH, and according to the timing relationship between the HS-DPCCH and the HS-PDSCH, the HS-DSCH is adopted by the HS-DPCCH at the time of the timing relationship. The feedback information of the carried downlink data (ie, ACK or NACK) and/or the CQI feedback of the downlink channel measured by the UE are sent to the NodeB.

The resource used by the UE to transmit the power control information, and the feedback information for transmitting the downlink data carried by the HS-DSCH and/or the resource used by the CQI are the default resources corresponding to the signature, or the resources indicated by the EAI to the UE. , or the resource indicated by the downlink physical channel.

In the first embodiment, the reserved signature adopted by the UE is specified by the network side, so the collision detection process is not required. The NodeB may also indicate the reserved signature and the uplink resource index corresponding to the signature in the downlink physical channel.

In the first embodiment, except that the reserved signature is used to distinguish the scenario in which the UE randomly accesses, the PRACH channel information or the access slot information may be distinguished. At this time, the network side may indicate the PRACH channel information or the access slot information used by the UE when the downlink physical channel indicates the independent HS-DPCCH uplink feedback, and may also broadcast the UE to use the independent HS-DPCCH uplink feedback when the uplink feedback is initiated in the system broadcast message. PRACH channel information or access slot information.

Another embodiment (indicating any signature and resource index )

In the second embodiment, signatures are not required for the scenario of initiating independent HS-DPCCH uplink feedback. The specific solution is as follows:

The UE in the CELL_FACH state needs to send HS-DPCCH uplink feedback, and there is no uplink data transmission:

The UE receives the indication information that is sent by the NodeB through the downlink physical channel (such as the HS-SCCH), and the indication information includes at least the H-RNTI, the signature index, and the resource index of the UE. For example, in the second embodiment, the signature may be Any of the 16 signatures does not require the network side to reserve for independent HS-DPCCH feedback. 2. After receiving the indication information sent by the downlink physical channel, the UE uses the signature of the indication information to initiate a random access procedure, and detects feedback information sent by the NodeB through the AICH to indicate whether the random access of the UE is successful.

After the UE detects the signature of the random access procedure, the NodeB replies with the feedback information in the AICH to indicate whether the random access of the UE is successful. The feedback information of the UE access success may be represented by a NACK. After detecting the NACK, the UE considers that the signature is used to initiate the random access success.

In the second embodiment, when the NACK is used to indicate the feedback information, the UE that needs to send the uplink data can be prevented from selecting the signature to initiate random access, and the resource corresponding to the signature is obtained.

4. After detecting the success of the random access, the UE sends the power control information to the NodeB through the DPCCH, and according to the timing relationship between the HS-DPCCH and the HS-PDSCH, the HS-DSCH is adopted by the HS-DPCCH at the time of the timing relationship. The feedback information of the downlink data (ie, ACK or NACK) and/or the CQI feedback of the downlink channel measured by the UE are sent to the NodeB, where there is no collision detection process; wherein the UE uses the resources used for transmitting the power control information, and sends the HS-DSCH The feedback information of the downlink data carried and/or the resources used by the CQI are resources indicated by the downlink physical channel.

Yet another embodiment (indicating any signature, resource reservation)

The UE receives the indication information that is sent by the NodeB through the downlink physical channel (such as the HS-SCCH), and the indication information includes at least the H-RNTI and the signature index of the UE.

2. After receiving the indication information sent by the downlink physical channel, the UE initiates a random access procedure by using the signature of the indication information, and detects feedback information that is sent by the NodeB to indicate whether the UE is successfully accessed by using the AICH.

3 After the NodeB detects the signature of the random access procedure initiated by the UE, it responds in the AICH. The information is used to indicate whether the random access of the UE is successful. The feedback information of the UE access success may be represented by a NACK. After detecting the NACK, the UE considers that signature is used to initiate random access.

In the third embodiment, when the NACK is used to indicate the feedback information, the UE that needs to send the uplink data can be prevented from selecting the signature to initiate the random access, and the resource is obtained.

4. After detecting the success of the random access, the UE sends the power control information to the NodeB through the DPCCH, and according to the timing relationship between the HS-DPCCH and the HS-PDSCH, the HS-DSCH is adopted by the HS-DPCCH at the time of the timing relationship. The feedback information of the downlink data to be carried (ie, the ACK/NACK) and/or the CQI feedback of the downlink channel measured by the UE are sent to the NodeB, where there is no collision detection process; wherein, the UE sends the power control information, and the downlink data carried by the HS-DSCH The resource used by the feedback information and/or the CQI of the downlink channel measured by the UE is a reserved resource corresponding to the signature on the HS-SCCH. The reserved resource corresponding to the signature may be a default resource of the signature configured in the system broadcast message, or may be a reserved resource other than the default resource specified for the HS-DPCCH feedback. For example, there are 4 signature indexes in the current cell, which are 1, 2, 3, 4, 8 resources in the current cell, and the indexes are integers of 1...8. In the random access for initiating uplink data, the default resource of signature 1 is the resource No. 1, the default resource of siganture 2 is the resource No. 2, the default resource of signature 3 is the resource No. 3, and the default resource of signature 4 is the resource No. 4. . In the random access for sending standalone HS-DPCCH, the default resource of signature 1 is resource number 5, the default resource of siganture 2 is resource number 6, the default resource of signature 3 is resource number 7, and the default resource of signature 4 is Resource No. 8.

Still another embodiment

The premise of the above three embodiments is that the current cell supports only one PRACH. If the current cell can support multiple PRACH channels, and one of the PRACH channels is dedicated to the scenario of independent HS-DPCCH uplink feedback, the following scheme can also be implemented:

The UE in the CELL_FACH state needs to send the HS-DPCCH uplink feedback, and When there is uplink data transmission:

The UE receives the indication information that is sent by the NodeB through the downlink physical channel (such as the HS-SCCH), where the indication information includes at least the H-RNTI, the PRACH channel information (such as the channel coding) and the signature index of the UE. Further, the indication information may also be Contains an upstream resource index (resource index);

2. After receiving the indication information sent by the downlink physical channel, the UE initiates a random access procedure by using the PRACH channel information of the indication information, and detects feedback information sent by the NodeB through the AICH to indicate whether the UE random access is successful.

3. After detecting the PRACH channel of the random access procedure, the NodeB replies with the feedback information in the downlink physical channel, and is used to indicate whether the random access of the UE is successful.

4. After detecting the success of the random access, the UE sends the power control information to the NodeB through the DPCCH, and according to the timing relationship between the HS-DPCCH and the HS-PDSCH, the HS-DSCH is adopted by the HS-DPCCH at the time of the timing relationship. The feedback information of the downlink data (ie, ACK/NACK) and/or the CQI feedback of the downlink channel measured by the UE are sent to the NodeB. The UE sends the power control information, the feedback information of the downlink data carried by the HS-DSCH, and/or The resources used by the CQI are the reserved resources corresponding to the signature on the HS-SCCH or the resources specified by the network side.

And the resource information of the random access, the UE may use the resource information to send the random access to the NodeB, and detect that the NodeB sends the downlink physical channel (for example, AICH/E-AGCH/E-RGCH, etc.) to indicate that the UE is randomly connected. If the feedback information indicates that the UE is successfully accessed, the UE may send the power control information to the NodeB through the DPCCH, and according to the timing relationship between the HS-DPCCH and the HS-PDSCH, pass the time relationship according to the timing relationship. The HS-DPCCH transmits the feedback information of the downlink data carried by the HS-DSCH and/or the CQI of the downlink channel measured by the UE to the NodeB. In the embodiment of the present invention, the UE can effectively report the downlink data feedback message carried by the HS-DSCH through the HS-DPCCH. The CQI feedback of the downlink channel measured by the UE and/or the UE can improve the utilization of the HS-DSCH resource and the downlink throughput.
