    Abstract: Methods and apparatuses in a wireless communication system. A method of operating a UE includes: receiving configuration information for TX resource pools including at least one of a first set of resource pools or a second set of resource pools; identifying, at an RRC sub-layer, the first and second set of resource pools based on a HARQ feedback channel; selecting, at a MAC sub-layer, a logical channel to transmit SL data, wherein the logical channel includes a highest priority among multiple logical channels using an LCP function; determining, at the MAC sub-layer, whether the logical channel is configured with the HARQ feedback channel; selecting, at the MAC sub-layer, a TX resource pool from the first set of resource pools based on a determination that the logical channel is configured with the HARQ feedback channel; and transmitting the SL data based on the TX resource pool.

    Abstract: The present disclosure relates to a communication technique for converging IoT technology and a 5G communication system for supporting higher data transmission rate after a 4G system, and a system thereof. The present disclosure can be applied to an intelligent service (for example, a smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, and security and safety related service etc.) based on 5G communication technology and IoT related technology. The present invention relates to a signal receiving method and apparatus of a terminal in device-to-device wireless communication. In the present invention, a D2D reception terminal can measure a DM RS transmitted together with a PSBCH or detect energy with respect to the entirety of or a part of a symbol region through which the PSBCH or DM RS in a synchronization subframe can be transmitted so as to enable use as a criterion for determining whether to retry PSBCH decoding. When a DM RS measurement level or an energy detecting level is larger than a certain threshold value, the D2D reception terminal recognizes that the PSBCH has been transmitted and may retry the PSBCH decoding for a certain time or a certain number of times. When a DM RS measurement level or an energy detecting level is smaller than a certain threshold value, the D2D reception terminal recognizes that the PSBCH has not been transmitted and may not retry the PSBCH decoding. When the PSBCH decoding is not retried, the D2D reception terminal can try other PSSS/SSSS detection. Through the present invention, the D2D reception terminal can avoid inefficient operation of retrying the PSBCH decoding for a certain time or a certain number of times despite non-transmission of the PSBCH.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. For licensed assisted access (LAA) technology used in a wireless communication system, an apparatus and a method for scheduling downlink data at a base station is provided. In the method, based on at least one part of parameters of a bearer to which the downlink data belongs, the base station determines a serving cell for scheduling the downlink data. Further, information about the identified serving cell is transmitted to a user equipment (UE).
