Embodiment Construction

[0036] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0037] In this embodiment, a method for reporting an uplink status report is provided, figure 1 is a flow chart of an uplink status report reporting method according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0038] Step S102, receiving RLC data (for example, RLC PDU) via the MAC-ehs entity, wherein the RLC data carries the expected sequence number range (referred to as the sequence number range) of the RLC data that is expected to be sent continuously by the MAC-ehs entity For example, in order to make minor changes to the existing RLC data, the start sequence number can be indicated by a special length indication of the RLC PD...

Abstract

The invention discloses an uplink status report reporting method, a radio link control data transmitting method and a device. The uplink status report reporting method includes the following steps that: the radio link control (RLC) data are received by an evolution high-speed downlink packet access media access control (MAC-ehs) entity, wherein the RLC data carry an initial sequence number of an expected-sequence number range of the RLC data that are expected to be transmitted continuously through the MAC-ehs entity; and it is determined whether to transmit the uplink status report or a status report of the RLC data which needs to be reported according to a current sequence number and the initial sequence number of the expected-sequence number range of the RLC data as well as received poll information (POLL) or a poll protocol data unit (POLL PDU). The uplink status report reporting method, the radio link control data transmitting method and the device in the invention enable an acceptor to correctly judge whether the RLC data are lost or not.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method for reporting an uplink status report, a method and a device for sending radio link control data. Background technique [0002] The radio link control (Radio Link Control, RLC for short) acknowledgment mode of the third generation mobile communication system ensures that the data (for example, Protocol Data Unit (Protocol Data Unit, short for short) The order of MAC-es PDU)) is the same as the order transmitted from the upper layer at the sending end. The RLC data PDU in the confirmation mode contains a sequence number field to provide a 12-bit (bit) sequence number, which is set in order when the data is sent ; Through the "error code error correction" request to retransmit the wrong PDU, the sending end requires the receiving end to send an acknowledgment response report to determine which received PDUs are wrong. [0003] Acknowledged Mode Radio Link Control (ab...
