Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] In the uplink transmission of the LTE system, the UE multiplexes each logical channel and limits the content of data transmission on semi-persistent scheduling resources. Arranged according to the priority of the logical channel, while assigning the transmission sequence, it ensures the normal transmission of semi-static data and reduces data transmission delay and segmentation overhead.

[0016] In the existing LTE standard, during the multiplexing process of uplink logical channels, the leaky bucket (Token Bucket) algorithm is used to perform priority processing and transmission bit number control among multiple logical channels of the same user, and the control plane (RRC) The layer will configure a priority value for each l...

Abstract

A multiplexin method for dispatching middle uplink logic channel in semi-static state of an LTE system comprises sending semi-static data by user UE on semi-static dispatching resources assigned on a base station, and data whose priority is higher than semi-static data on the semi-static dispatching resources are to be sent when the cycle of semi-static dispatching transmission reaches, UE generates conventional buffer state report BSR of high-priority data, the transmission of dispatching request SR is triggered when judging that residual resources after semi-static dispatching resources fill in semi-static data are insufficient for sending BSR and only semi-static dispatching resources exist. The embodiment of the invention can avoid increasing data transmission time delay and segmented overhead for semi-static dispatching.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, relates to a method for multiplexing uplink logical channels in semi-persistent scheduling of an LTE system. Background technique [0002] In order to meet the challenges of broadband access technology and meet the requirements of new services, the international standardization organization 3GPP started its long-term evolution (LTE) technology standardization work at the end of 2004. The LTE system adopts downlink Orthogonal Frequency Division Multiple Access (OFDMA) and uplink Single Carrier Frequency Division Multiple Access (SC-FDMA) access methods, and introduces multiple-input multiple-output (MIMO) technology to greatly improve transmission It can effectively resist multi-path interference, and can flexibly configure different bandwidths. In the case of 20M bandwidth, the target reaches the peak transmission rate of uplink 50Mbps and downlink 100M...
