Problems solved by technology

In addition to transitions between silence periods and talk bursts, if events such as transitions between AMR codec modes during voice communication occur, and periods in which a complete header packet is generated in a PDCP entity and in which The transition between the periods during which compressed header packets are generated presents the following problem: According to static scheduling, the data generated after the occurrence of the above events cannot be efficiently transmitted or received using radio resources allocated in advance

Embodiment Construction

[0037] Hereinafter, the structure, operation and other features of the present invention will be easily understood by illustrating preferred embodiments of the present invention illustrated in the accompanying drawings. The embodiments described below are examples in which the technical features of the present invention are applied to E-UMTS (Evolved Universal Mobile Telecommunications System).

[0038] image 3 The network structure of E-UMTS is illustrated. E-UMTS is a system evolved from conventional WCDMA UMTS, and its basic standardization is currently being handled by 3GPP (3rd Generation Partnership Project). E-UMTS may also be called an LTE (Long Term Evolution) system.

[0039] refer to image 3 , E-UTRAN includes base stations (hereinafter referred to as "eNode B" or "eNB"), wherein each eNB is connected to each other through an X2 interface. Also, each eNB is connected with a user equipment (UE) through a radio interface, and with an EPC (Evolved Packet Core) th...

Abstract

A method of data communication in a wireless communication system is disclosed. A method of receiving data in a user equipment of a wireless communication system comprises receiving scheduling information from a network, the scheduling information including downlink (DL) resource assignment information and an indicator; if the scheduling information includes a first UE identity and the first indicator has a first value, utilizing the scheduling information as configuration information of a persistent scheduling to receive a downlink data packet from the network; and if the scheduling information includes the first UE identity and the first indicator has a second value, utilizing the scheduling information to receive a retransmission data packet from the network.

Description

technical field [0001] The present invention relates to a wireless communication system, and more particularly, to a data communication method in the wireless communication system. Background technique [0002] In a wireless communication system using multiple carriers such as Orthogonal Frequency Division Multiple Access (OFDMA), or Single Carrier Frequency Division Multiple Access (SC-FDMA), a radio resource is a collection of contiguous subcarriers and is represented by time on a two-dimensional sphere - Frequency region definition. The time-frequency region is in rectangular form divided by time and subcarrier coordinates. In other words, one time-frequency region may be in the form of a rectangle divided by at least one symbol on the time axis and a plurality of subcarriers on the frequency axis. The time-frequency region may be allocated to uplink for a specific user equipment (UE), or the base station may transmit the time-frequency region to the specific user equip...
