Embodiment 1

[0060] The scenario based on this embodiment is: a timer is configured for each carrier frequency group.

[0061] image 3 It is a preferred flowchart of a method for reporting terminal scheduling information according to an embodiment of the present invention. Such as image 3 As shown, the method for reporting terminal scheduling information includes the following steps:

[0062] S302. The RNC configures the unified timer T-SI of each carrier frequency group to the UE through the RRC message. Here, the unified timer refers to the same timing time set on the timers of each carrier frequency group;

[0063] S304, once each carrier frequency group on the UE is authorized, immediately start the timer T-SI in the corresponding carrier frequency group, and at the same time, each carrier frequency performs data transmission according to the authorization situation;

[0064] S306, the UE detects that the timer T-SI of the carrier frequency group times out;

Abstract

The invention discloses a method and device for reporting terminal scheduling information. The method for reporting terminal scheduling information comprises the following steps: dividing carrier frequency used by a terminal into one or a plurality of carrier frequency groups; managing a timer by taking the carrier frequency group as a unit; judging whether the carrier frequency in each carrier frequency group is authorized; if yes, starting the timer of the current carrier frequency group, wherein the current carrier frequency group means the carrier frequency group in which the authorized carrier frequency is positioned; if the timer of the current carrier frequency group overtimes, sending the terminal scheduling information of the current carrier frequency group on one authorized carrier frequency in the carrier frequencies used by the terminal; and restarting the timer of the current carrier frequency group. According to the method and the device, the problem that an MAC (media access control)-i PDU (protocol data unit) space is occupied by information scheduling because each carrier frequency is forced to report when the timer overtimes can be solved, the air interface resource can be convenient to realize full utilization; and in addition, and a NodeB can better schedule uplink resources, thereby ensuring that UE can more effectively work.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for reporting terminal scheduling information. Background technique [0002] With the continuous development of the third-generation mobile communication, due to the relatively small capacity of single-carrier HSUPA (High Speed ​​Shared Uplink Physical Access) in TD-SCDMA (Time Division Synchronous Code Division Multiple Access) technology, it has been unable to meet the single-user uplink throughput. need. Therefore, in order to increase the data transmission rate and reduce transmission delay, it is necessary to introduce multi-carrier HSUPA technology. [0003] In HSUPA single-carrier technology, UE reports SI (scheduling information) to NodeB (Node B) through E-PUCH (Enhanced Uplink Physical Channel) channel or E-RUCCH (Enhanced Random Access Uplink Control Channel) channel. Request resources or notify the NodeB of the power headroom information of the ...
