Problems solved by technology
[0009] At present, the industry has proposed many solutions, such as not reporting the status of the buffer when the buffer queue of the terminal is empty or full, etc., but these solutions Most of the solutions only reduce the content of the report according to the status of the uplink transmission buffer queue in the terminal according to the agreement. The consideration is not comprehensive, and the reduction of the uplink overhead caused by the uplink scheduling information report is very limited.

Embodiment Construction
[0048]When the trigger condition for sending the uplink scheduling information report is met (for example, the timer expires or a trigger event occurs), the terminal will first generate a new uplink scheduling information report. According to the distinction of data service type and report content, etc., the uplink scheduling information may be divided into multiple parts, and these parts can be divided into different levels. For example, the uplink scheduling information can include information of all buffer queues in the terminal and power The information can include queue length, queue priority, and queue head data waiting time.
[0049] The technical solution provided by the invention is to divide all parts of the uplink scheduling information into two categories: the always report category and the condition report category. A report threshold is set for the parts belonging to the conditional report class. When generating the uplink scheduling information report, if the va...

The invention provides a method for reporting uplink dispatching information in a wireless communication system, which comprises the following steps: step 1. the uplink dispatching information required to be reported by a terminal is divided into a throughout reporting kind and / or a conditional reporting kind; after the terminal is accessed in a network, a reporting threshold for the uplink dispatching information in the conditional reporting kind is stated with a base station; step 2. when the terminal generates a current report of the uplink dispatching information, whether the uplink dispatching information in the conditional report kind reaches or exceeds the current report of the uplink dispatching information is determined; if the reporting threshold is reached or exceeded, the uplink dispatching information in the conditional reporting kind is added into the current report of the uplink dispatching information; if the reporting threshold is not reached or exceeded, the uplink dispatching information in the conditional reporting kind is not added into the current report of the uplink dispatching information, thus reducing the content in the report of the uplink dispatching information every time as much as possible.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a method for reporting uplink scheduling information in a wireless communication system. Background technique [0002] For wireless communication systems 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 affair...
