Embodiment Construction

[0085] figure 1 A wireless communication system according to some embodiments is shown. The system comprises a sending radio node 2 and a receiving radio node 4 . In some embodiments the transmitting radio node 2 is a wireless communication device (e.g. user equipment UE) and the receiving radio node 4 is a radio network node (e.g. base station BS), while in other embodiments the reverse is also true, i.e. The sending radio node 2 is a radio network node and the receiving radio node 4 is a wireless communication device.

[0086]The sending radio node 2 is configured to send the transmission 6 and the receiving radio node 4 is configured to receive the transmission 6 . Depending on the type of sending radio node 2 and receiving radio node 4, this transmission 6 may be an uplink transmission or a downlink transmission. As shown, transmission 6 includes at least a data block 6-1 (eg, a transport block) and data block 6-1 and one or more repetitions 6-2...6-N. However, it is w...

Abstract

A user equipment (2, 12A, 800A, 800B, 1000) is configured for use in a wireless communication system. The user equipment (2, 12A, 800A, 800B, 1000) is configured to transmit to a base station (4, 10,900A, 900B, 1100) a scheduled transmission (6) that comprises a data block and one or more repetitions of the data block. The scheduled transmission (6) in this regard is transmitted with transmissiongaps therein according to a transmission gap pattern (8) that specifies a pattern of transmission gaps in time. A base station (4, 10, 900A, 900B, 1100) may correspondingly be configured to receive from the user equipment (2, 12A, 800A, 800B, 1000) the scheduled transmission (6) with transmission gaps therein according to the transmission gap pattern (8).

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 62 / 277,465, filed January 11, 2016. technical field [0003] The present application relates generally to a wireless communication system, and in particular to the transmission and reception of data blocks in a wireless communication system. Background technique [0004] Currently, the 3rd Generation Partnership Project (3GPP) is standardizing a feature known as Narrowband Internet of Things (NB-IoT) to meet the requirements of Machine Type Communication (MTC) applications while maintaining compatibility with current Long Term Evolution (LTE) radio interfaces. backwards compatibility of the technology. NB-IoT transmission can occur within the frequency band of wideband LTE transmission, within the guard band of wideband LTE transmission, or within a separate spectrum. Regardless, communication of control information and payload data in a...
