Embodiment 1

[0098] The eNB allocates radio resources for the UE according to the current logical channel information of the UE and the quality information of the uplink channel, determines control signaling information for the allocated radio resources, and notifies the UE of the control signaling information of the radio resources. The logical channel priority processing process on the UE side is performed in the following steps:

[0099] According to the order of logical channel priority from high to low, allocate wireless resources to logical channels that have data to be transmitted and whose average data flow does not meet the PRB requirements of the logical channel;

[0100] If there are still resources remaining, the remaining resources are allocated to the logical channels with data to be transmitted in order of logical channel priorities from high to low. Logical channels of the same priority are allocated radio resources according to equal opportunities.

Embodiment 2

[0120] The eNB allocates radio resources for the UE according to the current logical channel information of the UE and the quality information of the uplink channel, determines control signaling information for the allocated radio resources, and notifies the UE of the control signaling information of the radio resources. If the control signaling information of radio resources includes packet error rate / block error rate / bit error rate or its level information, the logical channel priority processing process at the UE side is performed as follows:

[0121] According to the order of logical channel priority from high to low, allocate wireless resources to logical channels that have data to be transmitted and whose average data flow does not meet the PRB requirements of the logical channel;

[0122] If there are still resources remaining, the remaining resources are allocated to the logical channels with data to be transmitted in order of logical channel priorities from high to low...

Embodiment 3

[0152] The implementation of this embodiment is basically the same as that of the second embodiment above, and the control signaling information is still packet error rate, block error rate, bit error rate, etc., but the MCS is used to indicate, further reducing the overhead of control signaling.

[0153] The specific implementation is as follows:

[0154] Set the corresponding relationship table between MCS level and packet error rate, as shown in Table 2:

Abstract

The invention discloses an uplink radio resource dispatching method for a wireless communication system, which comprises that: an evolved base station distributes radio resource to a user terminal according to the current logical channel information of the user terminal and the quality information of an uplink channel, determines control signaling information of the radio resource, and informs the user terminal of the control signaling information of the radio resource. Or, after receiving the control signaling information of the radio resource transmitted by the evolved base station, the user terminal selects the corresponding radio resource for the logical channel according to the service quality requirement of the logical channel and the control signaling information of the radio resource. The invention discloses a device for implementing the uplink radio resource dispatching method for the wireless communication system at the same time. The method and the device greatly improve the matching degree of the UE on the radio resource dispatching strategy of the eNB, and furthest promote the throughput and capacity of the system under the condition of meeting basic QoS.

Description

technical field [0001] The present invention relates to an uplink wireless resource scheduling technology in a mobile communication system, in particular to an uplink wireless resource scheduling method and device based on carrier aggregation technology in an advanced long-term evolution (LTE-A, Long Term Evolution-Advanced) system. Background technique [0002] In the Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network) of the third-generation mobile communication Long Term Evolution (LTE, Long Term Evolution) system, uplink data is transmitted through an uplink shared channel. Resources are allocated to each user terminal by an evolved base station (eNB, EvolvedNodeB). The access technology adopted by E-UTRAN is Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) technology. Compared with the second-generation mobile communication system, the radio resource management of E...
