[23] Specific implementation

[24] In the embodiment of the present invention, the base station device sends, to the UE, indication information that carries the control UE to release the uplink resource. Message.

[25] After acquiring the data volume information to be sent reported by the UE, the base station device determines, according to the data volume information, whether the UE needs to control the uplink resource to be released.

[26] The base station device may further determine, according to the usage of the uplink resource, whether the UE needs to be controlled to release its uplink resource.

[27] The above uplink resources mainly include: a public enhanced dedicated channel E-DCH resource, and the foregoing message may be: physical layer signaling. The above physical layer signaling may be E-AGCH (E-DCH Absolute Grant)

Channel, the enhanced dedicated channel absolute grant channel) signaling, the base station device carries the indication by the control information of the E-AGCH signaling, and the UE releases the uplink resource information, and sends the E-AGCH signaling to the UE.

[28] The above physical layer signaling can also be HS-SCCH (Shared Control Channel for

HS-DSCH, HS-DSCH shared control channel) signaling, the base station device carries the indication by the HS-SCCH signaling to release the uplink resource information, and sends the HS-SCCH signaling to the UE.

[29] In order to better describe the embodiments of the present invention, the following describes the E-AGCH and HS-SCCH signaling.

[30] 1, E-AGCH is to achieve Node

A downlink shared control channel added by the B to the scheduling of the uplink E-DCH resource, where the control information carried by the channel includes: absolute grant value information and absolute grant range information. The UE obtains its own service grant based on the value of the absolute grant received, and performs E-TFC (E-DCH Transport Format Combination) selection according to the service. The above absolute permitted value represents the absolute power offset of the E-DCH, which can be represented by 5 bits, a total of 32 values, one of which is "INACTIVE", used to control HARQ (Hybrid Automatic Repeat)

Request, hybrid automatic repeat request) The inactivation of the process. The absolute grant range information can be expressed in 1 bit to control whether the active and inactive HARQ processes are current or all processes.

[31] UEs using E-DCH resources have both primary and secondary E-RNTI (E-DCH Radio Network)

Temporary

Identifier, E-DCH wireless network identification, the UE obtains the absolute permission values of the scheduling-based transmission and the non-scheduled transmission based on the primary and secondary E-RNTIs, respectively. When the value of the absolute grant obtained by the UE through the primary RNTI is "INACTIVE", the obtained absolute grant range information indicates the HARQ process control of the UE. The range is for all processes, and the UE switches to a value that is absolutely granted by the secondary E-RNTI.

[32] 2. HS-SCCH is a downlink control channel used to transmit control information related to HS-PDSCH. The HS-S CCH currently has three formats: typel (format 1) for normal mode, type2 (format 2) for HS-SCCH less (high-speed shared control channel saving) mode, and MIMO (Multiple-) Input

Type3 (Format 3) in Multiple-Out-put, Multiple Input Multiple Output mode. In typel and type3, it is also possible to indicate whether the carried is HS-SCCH order (HS-SCCH order) by using a specific control bit field in the format, HS-SCCH

Order is mainly used to transmit physical layer commands, currently HS-SCCH

The physical layer command that order can carry is DTX/DRX (Discontinuous Transmission/

Discontinuous

Reception, discontinuous transmission / discontinuous reception) commands. The order is expressed by the HS-SCCH order$3⁄4^ border type and the ordert匕 temple 旨

Type="000", which means that the non-continuous transmission/discontinuous reception command is carried, order="xord,l, xord,2, xord,3", xord, 1=1 and 0 respectively indicate the activation and non-continuous reception. Activation, xord, 2=l and 0 respectively indicate activation and deactivation of discontinuous transmission, xord, 3 are reserved bits.

[33] The above is the current situation for the two channels for the E-AGCH and HS-SCCH channels. If the information about the two channels is changed, the embodiment of the present invention can process according to the modified information.

[34] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. The method and apparatus of the embodiments of the present invention are applicable to base station devices in various wireless communication systems.

For example, the specific processing procedure of the method for controlling the UE to release the uplink resource in the embodiment of the present invention is as shown in FIG. 1 , and includes the following steps:

[35] Step 1-1, Node

The B obtains the usage of the uplink resource of the UE according to the data volume information that is sent by the UE.

[36] After the UE successfully acquires the uplink resource (mainly the E-DCH resource) through the physical layer random access process, the UE uses the uplink resource according to the set time interval.

The B reports the scheduling information, where the scheduling information mainly includes the amount of data that the UE needs to send.

[37] Node After receiving the scheduling information reported by the UE, the B may obtain the data volume information that the UE needs to send according to the scheduling information, and determine, according to the data volume information, whether the UE needs to control the uplink resource.

[38] Steps 1-2, Node

B determines that the UE needs to control the UE to release its uplink resource, and sends a physical layer signaling carrying the information indicating that it releases the uplink resource to the UE.

[39] When the data amount information currently needed to be sent by the UE is lower than a set threshold, then Node

B determines that it is necessary to control the UE to release its uplink resources. So, Node

The B sends a physical layer signaling that carries the information indicating that the uplink resource is released to the UE, where the indication information may include the moment when the UE specifically releases the uplink resource, where the physical layer signaling may be E-AGCH signaling and HS-SCCH signaling. .

[40] Taking E-AGCH signaling as an example, Node

B can express the above indication information by the absolute permission value information and the absolute permission range information described above. In practical applications, a specified absolute grant value information or absolute grant range information, or a specified combination of absolute grant value information and absolute grant range information may be set to represent the foregoing indication information.

[41] In the specific case, the above indication information may also be represented by a combination of the existing absolute permission value information and the absolute permission range information. For example, when Node

CELL-FACH (CELL-Forward Access) between B and UE

Channel, cell forward access channel) E-DCH transmission of the state, the number of E-DCH resources that the UE can use is limited, and the number of UEs using the E-DCH resource is also limited. In this case, the UE may not use the transmission based on the common scheduling, that is, the handover between the primary and secondary E-RNTIs is not necessary, and only the primary E-RNTI is configured for the UE. Therefore, the above-mentioned indication information can be represented by using the above-mentioned existing absolute grant value "INACTIVE" and the absolute grant range information indicating that the HARQ process control range of the UE is a combination of all processes.

[42] Taking HS-SCCH signaling as an example, a designated HS-SCCH can be passed.

Order to carry the above instructions. For example, specify Order type="001"

Or other specific bit combinations to represent the above indication information.

[43] Step 1-3: The UE releases the uplink resource used by the UE according to the received indication information.

[44] After receiving the physical layer signaling carrying the indication information, the UE immediately releases or encapsulates in the indication information. The specified source contains the uplink resources it uses.

[45] In practice, to avoid Node

B indicates that the UE has released the uplink resource used by the UE, but the UE has uplink interference caused by frequent random access due to data transmission, and may also carry the waiting occasion for the next time the UE initiates random access in the indication information. . The above-mentioned absolute permission value information, absolute permission range information, HS-SCCH can also be used in the waiting time.

Order to indicate. For example, a specific representation method may be: Waiting time is 256 ms, and the unit waiting for the waiting time between the Node B and the UE is 128 ms. Therefore, the absolute permission value is 2, and the absolute permission value is sent. Give the UE. After the UE waits for the above-mentioned waiting time, the UE initiates the random access procedure again.
