Description

Waiting for authorization on the control channel), only the UE receiving the grant on the PDCCH can perform uplink data transmission. After receiving the authorization on the PDCCH, the UE feeds back the uplink data through the PHICH (Physical Hybrid ARQ Indicator Channel). In the foregoing scenario, when a large number of packet services exist in the uplink, the transmission of each packet service needs to occupy the PDCCH, so that the number of PDCCH occupied channel resources increases, and when the total number of channel resources is constant, the uplink capacity is limited.

Further, after receiving the foregoing start condition, the user terminal may confirm whether the data service status of the user meets one or more of the start conditions, and if the data service status of the user meets one or more of the start conditions, the base station Send a confirmation message. If its own data business status does not match Any one of the dynamic conditions can track and check the status of its own data business in real time until its own data service status meets one or more of the starting conditions. For example, the data service in the active state in the connected state includes mobile surfing, network games, data packet downloading, etc., wherein the data packet is downloaded as a designated data service, and the user terminal can confirm that the data service status of the user is consistent. Start condition.

The receiving unit 602 is configured to obtain an acknowledgement message sent by the user terminal when confirming that the current data service meets the start condition.

Optionally, the confirmation message sent by the user terminal by using the MAC control information unit when confirming that the current data service meets the start condition may be obtained. The MAC control information element is used to transmit a message of the MAC layer, and the user terminal can use the MAC control information element to notify the eNodeB of the size of the data to be sent currently. In the MAC PDU format, the MAC header is located before the MAC Control Information Element, and the LCID in the MAC header can be used to indicate the message type of the MAC Control Information Element.

Optionally, an acknowledgement message sent by the user terminal by using dedicated signaling when the current data service is confirmed to meet the start condition may be obtained. The dedicated signaling can guide the user terminal to establish a temporary communication channel with the base station and operate in cooperation.

Optionally, the scheduling request that is sent by the user terminal to confirm that the current data service meets the start condition is performed, and the scheduling request is performed by using a wireless network identifier RNTI, where the wireless network is scrambled. The identifier is sent by the high layer signaling, and the RNTI is used to distinguish the scheduling request sent by the user terminal. In a specific implementation, each user terminal may periodically send a scheduling request at a fixed location of the pre-configured PUCCH channel of the eNodeB, thereby requesting scheduling resources from the eNodeB. The scheduling request is transmitted by using code division multiplexing, and multiple user terminals can occupy the same time-frequency resource and distinguish by different code words.

The processing unit 603 is configured to start uplink enhanced transmission according to the acknowledgement message.

Optionally, the number of user terminals that currently send the acknowledgment message may be counted, and when the number of user terminals that send the acknowledgment message reaches a first preset threshold, uplink enhanced transmission is started.

Optionally, the number of channel resources occupied by the current downlink common control channel may be calculated, and when the number of channel resources occupied by the downlink common control channel reaches a second preset threshold, uplink enhanced transmission is started. The LTE system defines two dedicated channel resource units: a resource particle group REG and a control channel unit CCE, and one CCE is composed of 9 REGs. In a specific implementation, the number of CCEs occupied by the downlink common control channel depends on the downlink channel environment in which the UE is located. For a user terminal with a good downlink channel environment, the eNodeB may only need to allocate one CCE, and for the user terminal with a poor downlink channel environment, The eNodeB may need to allocate up to 8 CCEs. Therefore, by counting the number of channel resources allocated by all user terminals, the number of channel resources occupied by the current downlink common control channel can be calculated.

Optionally, the number of user terminals that currently send the acknowledgment message is counted, and the number of channel resources occupied by the current downlink common control channel is calculated; when the number of user terminals that send the acknowledgment message reaches a first preset threshold, And when the number of channel resources occupied by the downlink common control channel reaches a second preset threshold, the uplink enhanced transmission is started.

Further, the sending unit 602 is further configured to send, to the user terminal, indication information for initiating uplink enhanced transmission, so that the user terminal performs uplink data transmission by using the initiated uplink enhanced transmission.
