Abstract: A method for accessing a cellular communications network in unlicensed spectrum is provided. More specifically, the method is related to performing a Listen-Before-Talk (LBT) procedure prior to transmitting a Physical Random Access Channel (PRACH) preamble for accessing a New Radio-Unlicensed (NR-U) network. A User Equipment (UE) first performs the LBT procedure. If the LBT procedure is successful, the UE then generates a punctured PRACH preamble and transmits the punctured PRACH preamble. By puncturing the PRACH preamble, it is possible to create a gap(s) for performing the LBT procedure in a way that is backward compatible with existing NR-U specification and does not reduce a number of random access occasions in a slot or a mini-slot. As a result, it is possible to transmit PRACH preambles in consecutive random access occasions, thus helping to increase spectrum utilization and reduce latency in the cellular communications network.

Abstract: The present disclosure relates to transmitting synchronization signals and in particular to so called beam sweep. In particular the disclosure relates to methods for providing synchronization using synchronization sequences that are transmitted at different points in time. The disclosure also relates to corresponding devices and computer programs. A method in a network node, for transmitting synchronization sequences of a synchronization signal to one or more receiving wireless devices, comprises determining multiple synchronization sequences, such that each synchronization sequence comprises a respective timing indication, whereby each synchronization sequence enables determination of a time of an event in a receiving wireless device and transmitting the synchronization sequences to the one or more wireless devices, at different points in time.

Abstract: The present disclosure generally relates to the field of resource allocation. More specifically, the present disclosure relates to a technique of allocating communication resources in a wireless communication network. The wireless communication network comprises a plurality of access nodes, each of the plurality of access nodes being connected to one or more of the plurality of access nodes via one or more links to provide a plurality of routes for routing data through the wireless communication network. A method embodiment comprises the step of receiving, for one or more links (180, 182) of at least one access node (100) of the plurality of access nodes, allocation information. The allocation information indicates how available communication resources are to be allocated. The method comprises allocating, for the one or more links (180, 182) of the at least one access node (100), the available communication resources based on the received allocation information and a status of one or more data buffers of the at least one access node (100) for buffering data related to one or more of the plurality of routes.

Abstract: Various embodiments of the present disclosure provide methods and apparatuses for determining radio network temporary identifier (RNTI) in a two-step random access procedure. A method of a terminal device, comprising: determining a request message for random access, wherein the request message comprises a preamble and a physical uplink shared channel, PUSCH, message and the PUSCH message is determined based on a first radio network temporary identity, RNTI; transmitting the request message; and obtaining a response message for random access based on a second RNTI, wherein the first RNTI and the second RNTI are the same or different.

Abstract: A wireless device (12, 50) obtains a window of time for bundling of a set of uplink transmissions (20) on a carrier or bandwidth part. The wireless device determines whether or not to apply a timing advance adjustment (16) within the window of time. The timing advance adjustment comprises an adjustment to a transmission timing of an uplink transmission on the carrier or bandwidth part. The wireless device transmits the uplink transmission on the carrier or bandwidth part during the window of time using a transmission timing which is in accordance with the determining. The determining is based on whether the timing advance adjustment is indicated by a received timing advance command (18) or whether the timing advance adjustment is due to a detected error in downlink timing.
