Embodiment Construction

[0044] The technical features described below can be used through the communication standard of the 3rd Generation Partnership Project (3GPP) standardization organization, the communication standard of the Institute of Electrical and Electronics Engineers (IEEE), and the like. For example, the communication standards of the 3GPP standardization organization include Long Term Evolution (LTE) and / or the evolution of the LTE system. Evolutions of LTE systems include LTE-Advanced (LTE-A), LTE-A Pro, and / or 5G New Radio (NR). Communication standards of the IEEE standardization organization include wireless local area network (WLAN) systems, such as IEEE 802.11a / b / g / n / ac / ax. The systems described above use various multiple access techniques such as Orthogonal Frequency Division Multiple Access (OFDMA) and / or Single-Carrier Frequency Division Multiple Access (SC-FDMA) for the downlink (DL) and / or uplink (UL) . For example, only OFDMA can be used for DL, and only SC-FDMA can be used...

Abstract

The invention relates to transmission prioritization in wireless communications. According to an embodiment of the present invention, a method performed by a wireless device in a wireless communication system comprises: configuring a threshold; creating a Media Access Control (MAC) Protocol Data Unit (MAC PDU) for a sidelink comprising a Media Access Control (MAC) Control Element (CE); setting a priority value for the MAC CE; identifying a transmission of the MAC PDU for the sidelink and an uplink transmission to be performed; determining that the transmission of the MACPDU for the side link and the uplink transmission cannot be performed at the same time; determining that the priority value of the MAC CE is lower than a threshold value; the MAC PDU transmission used for the side link is prior to the uplink transmission; and performing a transmission of the MAC PDU for the sidelink prioritized over the UL transmission.

Description

technical field [0001] The present disclosure relates to transmission prioritization in wireless communications. Background technique [0002] 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) is a technology for enabling high-speed packet communications. Many schemes have been proposed for LTE goals, including those aimed at reducing user and provider costs, improving quality of service, and extending and improving coverage and system capacity. 3GPP LTE requires lower cost per bit, increased service availability, flexible use of frequency bands, simple structure, open interface, and appropriate terminal power consumption as higher-level requirements. [0003] The International Telecommunication Union (ITU) and 3GPP have begun work to develop requirements and specifications for New Radio (NR) systems. 3GPP had to identify and develop the technical components needed to successfully standardize new RATs both in a timely manner to meet urgent market needs an...
