Problems solved by technology

A problem with this scheme is therefore that downlink transmission resources will be used for CB grants which in many cases will not result in any transmission, thus wasting transmission capacity and creating unnecessary interference
Another problem is that the transmission of CB grants may hinder the use of DTX in scenarios with little or no other activity, which will thereby increase eNB power consumption and interference

Abstract

The present invention relates to a user equipment and a radio base station, and to related methods of enabling contention-based uplink transmission. The method comprises the steps of determining (210) configuration information for at least one contention-based uplink transmission opportunity, transmitting (220) the configuration information to at least one user equipment, and for each of the at least one contention-based uplink transmission opportunity, transmitting (230) an access control signal to the at least one user equipment, indicating whether contention-based uplink transmission is allowed for the opportunity.

Description

technical field [0001] The present invention relates to contention-based uplink transmission in wireless communication systems. In particular, the present invention relates to a method, user equipment and radio base station enabling contention-based uplink transmission. Background technique [0002] Universal Mobile Telecommunications System (UMTS) is one of the third generation mobile communication technologies designed to succeed GSM. 3GPP Long Term Evolution (LTE) is a 3rd Generation Partnership Project (3GPP) initiative to improve the UMTS standard in terms of improved services such as higher data rate, improved efficiency, reduced cost, etc. to cope with future requirements. within the plan. Universal Terrestrial Radio Access Network (UTRAN) is a radio access network of UMTS and Evolved UTRAN (E-UTRAN) is a radio access network of LTE system. like Figure 1a As shown, in E-UTRAN, user equipment (UE) 150 is wirelessly connected to radio base stations (RBS) 110a-c, com...
