    Abstract: A method for transmitting a signal in a wireless communication system. The method includes receiving, from a base station, random access configuration information of a normal UE. The method also includes determining random access configuration information of an integrated Access and Backhaul (IAB) UE from the received random access configuration information of the normal UE based on information indicating relationship between the random access configuration information of the normal UE and the random access configuration information of the IAB UE. The method further includes transmitting, to the base station, a preamble using the determined random access configuration information of the IAB UE.

    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure relates to the technical filed of wireless communication, and particularly, to a method for random access. The method comprises the steps of transmitting a random access signal comprising a preamble sequence and a payload from a terminal to a base station, wherein the preamble sequence is configured randomly or according to size of the data to be transmitted and the payload is configured according to current service requirements; and receiving by the terminal feedback information transmitted back by the base station which corresponds to the random access signal, wherein the feedback information comprises at least one of unique user identification information, timing advance information, uplink transmission grant information, and acknowledgement (ACK) signal/negative acknowledgement (NACK) signal. The present solution may use two interactive steps to realize the function that is realized through four interactive steps in the prior art by designing the random access signal such that it comprises the preamble sequence and the payload, therefore it can reduce access delay in data transmission.

    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a differential beamforming based random access method, base station, and user equipment, wherein the differential beamforming based random access method comprises, by a base station: receiving a preamble sequence from a first terminal in a differential beamforming receiving mode; determining a base station beam direction angular deviation based on the preamble sequence; and adjusting a base station beam according to the base station beam direction angular deviation, and transmitting a random access response signal to the first terminal through the adjusted base station beam. In the present disclosure, by detecting a base station beam direction angular deviation in a differential beamforming receiving mode, a base station receiving beam can be adjusted to an optimal beam faster than a beam polling way of the prior art, thereby improving the performance of a random access procedure.

    Abstract: A method and an apparatus for transmitting uplink demodulation reference signals (DMRSs) is provided. The method includes a user equipment (UE) determines an uplink DMRS format for demodulating a physical uplink shared channel (PUSCH) according to frequency-domain resources occupied by the PUSCH, in which the uplink DMRS format includes a comb occupied by a PUSCH DMRS sequence. The comb is subcarriers having specified intervals occupied by demodulation reference signals, and the specified intervals between the occupied subcarriers are same. For the DMRSs using the comb format, subcarriers with specific intervals are used for channel estimation, and values of the channel estimation are used for data demodulation. The UE transmits uplink information and the demodulation reference signals on physical resources using the uplink DMRS format. The present disclosure can improve the multiplexing ratio of uplink physical resources in a multi-UE scenario.
