摘要： Methods, network device and terminal device are disclosed time advance adjustment. A method comprises receiving a time advance, TA, command from a network device; determining a TA granularity or range; and determining a TA value based at least partly on the TA command and the TA granularity or range, wherein different numerologies are configured for at least two carriers and/or at least two bandwidth parts (BWPs) in one carrier, wherein the at least two carriers and/or the at least two BWPs serve the terminal device and/or the terminal device supports at least one numerology.

摘要： There is disclosed a User Equipment for a MulteFire wireless communication network. The User Equipment comprises processing circuitry and a transmitter, the User Equipment being adapted for utilizing the processing circuitry and the transmitter for performing a Listen-Before-Talk (LBT) procedure for one or more transmission bandwidths; transmitting Physical Uplink Shared CHannel (PUSCH) signaling in a PUSCH subframe on one or more interlaces within the one or more transmission bandwidths; and transmitting Sounding Reference Signaling on the one or more interlaces in the PUSCH subframe.

摘要： Techniques are disclosed for transmitting and receiving a user-specific transmission comprising user data symbols and user-specific reference signal symbols. According to one aspect, a method comprises transmitting, within a group of time-frequency resources scheduled in a first time interval for a first user, a plurality of demodulation reference signal (DMRS) symbols, where the plurality of DMRS symbols within the group of time-frequency resources are more densely arranged in the frequency domain than in the time domain; and transmitting, within the group of time-frequency resources scheduled in the first time interval for the first user, a plurality of synchronization signal (SS) symbols, where the plurality of SS symbols within the group of time-frequency resources are more densely arranged in the time domain than in the frequency domain.

摘要： A method in a wireless device for performing random access to a network node. The method comprises receiving a set of downlink beam-specific reference signals, BRS, from the network node, and determining a preferred BRS based on the received signal power for each BRS. The method also comprises selecting, based on the preferred BRS, a random-access resource to be used for transmitting a random-access attempt to the network node, as well as using the selected random-access resource when transmitting a random-access attempt to the network node, whereby the selection of random-access resource indicates to the network node which downlink beam is preferred by the wireless device to be used for downlink transmissions.
