Embodiment Construction

[0028] The present invention proposes a method for realizing an uplink scheduling request in an LTE system, such as image 3 As shown, the specific method is as follows:

[0029] Step 301, the base station determines the time interval for allocating uplink resources required for sending uplink scheduling information to the terminal according to the service situation of the terminal;

[0030] Step 302, the base station provides the terminal with the uplink resources required for sending uplink scheduling information through the layer 1 / layer 2 (L1 / L2) control channel using the above time interval or according to the uplink scheduling request of the terminal;

[0031] Step 303, the terminal sends the uplink scheduling information including the "emergency" flag field in the above resource.

[0032] Wherein, the "emergency" flag field in the uplink scheduling information is used to indicate whether the terminal requests priority uplink scheduling.

[0033] Step 304 , the base st...

Abstract

The invention provides a method for requesting uplink scheduling in a long-term evolution system. The method comprises the following steps: firstly, a base station distributes and sends uplink resources required for uplink scheduling information to a terminal; secondly, the terminal sends the uplink scheduling information containing an 'emergency' tag field in the uplink resources; and thirdly, after being received by the base station, the uplink scheduling information is adjusted to a strategy of the uplink resources required for the uplink scheduling information distributed and sent by the terminal according to the 'emergency' tag field. In the method, the base station adjusts the priority order of the terminal in the uplink resource distribution according to the 'emergency' tag field in the uplink scheduling information and / or adjusts and sends the interval of the uplink resource required for the uplink scheduling information for the terminal, thus effectively reducing the cost of requesting the uplink dispatching on the premise of satisfying the service performance of the terminal.

Description

technical field [0001] The invention relates to the field of long-term evolution (LTE) communication, in particular to an uplink scheduling request method in a long-term evolution communication system. Background technique [0002] LTE communication system see figure 1 , mainly composed of a terminal 110 , a base station 120 and a core network 130 . The base stations 120 can have logical or physical connections according to the needs. The network composed of the base stations 120 is called a radio access network (RAN), which is responsible for the access layer affairs, such as the management of wireless resources; the uplink and downlink wireless resources follow the shared channel The mode is carried out by the base station in charge of scheduling. The base stations 120 are all connected to the core network 130 , and each base station 120 may be connected to one or more than one core network node (CN) 130 . The core network 130 is responsible for non-access stratum affai...
