Problems solved by technology

Additionally, Rel-13 low-complexity wireless devices typically require multiple iterations to send random access attempts
Therefore, although coverage enhancement through random access message repetition has been proposed, solutions suitable or adapted for low-complexity wireless devices are still needed

Abstract

The present disclosure relates to methods for random access message repetition, and wireless devices and network nodes for performing these methods. When performed by a wireless device in a wireless network, the method includes: selecting (S11) a random access channel RACH resource associated with a RACH configuration repeated for random access messages, the RACH configuration for a single random The access attempt has a predetermined number of repetitions; and for the single random access attempt, a random access message is sent (S14) with the predetermined number of repetitions using the selected RACH resource.

Description

technical field [0001] The present disclosure relates to random access procedures. The present disclosure relates to methods for random access message repetition, and wireless devices and network nodes for performing these methods. Background technique [0002] 3GPP Long Term Evolution LTE is developed under the 3rd Generation Partnership Project 3GPP to improve the Universal Mobile Telecommunications System UMTS standard in response to future demands for improved services such as higher data rates, increased efficiency, and reduced costs The fourth generation mobile communication technology standard. The Universal Terrestrial Radio Access Network UTRAN is the radio access network of the UMTS, and the evolved UTRAN, namely E-UTRAN, is the radio access network of the LTE system. In UTRAN and E-UTRAN, User Equipment (UE) is wirelessly connected with a Radio Base Station (RBS), which is usually called NodeB (NB) in UMTS and evolved NodeB, eNodeB in LTE or eNodeBs. RBS is a ...
