Abstract: According to an aspect, there is provided an access node for configuring relaying using one or more terminal devices. The access node is configured to select the one or more terminal devices connected to the access node for relaying a signal from the source terminal device to the access node based on radio link measurements. Further, the access node is configured to configure each of the one or more terminal devices to decode each received primary uplink resource and if the decoding is successful, to cause transmitting a transport block corresponding to the decoded primary uplink resource on a secondary uplink resource using a pre-defined starting position to a target network node. The access node is also configured to receive at least one transport block transmitted from the source terminal device via one or more terminal devices on one or more secondary uplink resources.

Abstract: A UE performs first control channel monitoring according to a first CORESET and first search space set configuration(s), the first control channel monitoring performed on n subbands, n>1, able to be transmitted by a base station in an unlicensed band carrier. The UE determines, in response to a detection of a control channel in the monitoring and from the control channel, transmission bandwidth configuration to be used by the base station in the unlicensed band carrier for control channels. The UE performs second control channel monitoring according to a second CORESET and at least one second search space set configuration. The second control channel monitoring is performed on m subbands, m≤n, in the unlicensed band carrier, the m subbands being a subset of the n of subbands. A base station determines which subbands are available for use and transmits the transmission bandwidth configuration to the UE based thereon.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for HARQ retransmission for HARQ feedback. In example embodiments, a first device receives, from a second device, hybrid automatic repeat request, HARQ, negative acknowledgement, NACK, feedback for a data unit in a HARQ process. Moreover, the first device retransmits, to the second device, the data unit in the HARQ process and at least one data unit in at least one subsequent HARQ process, regardless of receiving HARQ feedback for the at least one data unit in the at least one subsequent HARQ process.

Abstract: An example method includes determining at least a first search space configuration and a second search space configuration; determining a first set of periodic search spans formed by a first subset of time-domain symbols of each search window in the first set of periodic search windows and further determining a second set of periodic search spans; forming a sequence of search spans from the first set of periodic search spans and the second set of periodic search spans and determining a virtual search window; determining a maximum number of downlink control information candidates; searching the received signal within the virtual search window for up to the maximum number of downlink control channel candidates and omitting the searching for remaining downlink control channel candidates and, upon detecting the downlink control channel, extracting downlink control information on the downlink control channel.

Abstract: The present disclosure relates to a technique for configuring signal measurements to be performed for a wireless communication channel. More specifically, a network node generates a first timing configuration for the wireless communication channel and sends it to a UE. The first timing configuration defines a sequence of Fixed Frame Periods (FFPs). Then, the network node generates a second timing configuration for the wireless communication channel and sends it to the UE. The second timing configuration comprises an indication for the UE to perform the signal measurements (e.g., RSSI measurements) within at least part of an idle period of at least one FFP of the sequence of FFPs. By so doing, it is possible (by using a limited signaling overhead) to ensure that the signal measurements will be always performed within the idle period(s) of the FFP(s). In some embodiments, the indication may cause the UE to perform the signal measurements within the at least part of every N-th FFP (e.g., every second FFP) of the sequence of FFPs, thereby providing a more flexible configuration of the signal measurements in a wireless communication network.

Abstract: There is provided a user equipment apparatus that includes at least one processor and at least one memory. The memory stores instructions which, when executed by the at least one processor, cause the user equipment apparatus at least to: perform an initial cell search of one or more cells on a network, including scanning for synchronization signal block (SSB) transmissions corresponding to synchronization raster points; receive an SSB transmission associated with a synchronization raster point and with a transmission bandwidth, where a size of the transmission bandwidth is based on location of the synchronization raster point in a band having at least a first region and a second region, and where the SSB transmission includes a physical broadcast channel (PBCH); and determine a PBCH puncturing pattern for receiving the PBCH based on the size of the transmission bandwidth.

Abstract: There are provided measures for enabling/realizing support for idle period communication in semi-static channel access. Such measures exemplarily comprise that a user equipment device monitors for presence of a clearance indication provided by a base station device serving the user equipment device, which indicates clearance for communication by the user equipment device in at least one idle period of abase station device frame period, disables communication by the user equipment device in the at least one idle period of the base station device frame period when the monitoring yields absence of the clearance indication, and enables communication by the user equipment device in the at least one idle period of the base station device frame period when the monitoring yields presence of the clearance indication.
