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: Systems, methods, apparatuses, and computer program products for handling measurement gaps for frame based equipment (FBE) operation are provided. One method may include receiving at a user equipment, from a serving cell, assistance information that includes at least one of a fixed frame period (FFP) configuration of the serving cell, a reference signal timing configuration for at least one neighbor cell and system frame number (SFN) and frame timing difference reporting information for the at least one neighbor cell. The method may also include determining whether there is transmission from the serving cell during a period of time and, in accordance with a determination that there is no transmission from the serving cell during the period of time, based at least on the assistance information, performing measurement of the at least one neighbor cell during the period of time.

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.

Abstract: A network node allocates primary frequency resources and at least one secondary frequency resource to a user equipment (UE) within a dynamically changing bandwidth (BW) of a cell served by the network node. The network node further configures the UE to use the primary frequency resources for an UL transmission when the primary frequency resources fall within an UL part of the BW, and to use the secondary frequency resource for the UL transmission when the primary frequency resources fall, at least partly, within a downlink (DL) part and/or a Guard Band (GB) of the BW, and/or fall, at least partly, outside the BW. The UE may dynamically, based on such configuration from the network node, adapt its resource allocation to perform the UL transmission even if the primary frequency resources are not fully within the UL part of the BW in a current time resource.

Abstract: A transmitter is configured to set a counter to a starting value, sense whether a channel is busy or idle and to update the counter value during sensing. When there is data to be transmitted, the transmitter is configured to determine, based on at least the counter value at a transmit opportunity and a duration the channel has been sensed idle before the transmit opportunity, whether to transmit the data or to continue the sensing the channel to a next transmit opportunity without reset- ting the counter value to the starting value.

Abstract: Embodiments of the present disclosure relate to bit reduction in resource information. According to embodiments of the present disclosure, the number of bits to indicate the resource allocation is reduced and the network device generate the control information based on an offset associated with the bit reduction. In this way, multiple transmission opportunities for the transmission of Msg3 of the random access procedure are provided without increasing the signaling overhead.

Abstract: Various communication systems may benefit from improved handover techniques. For example, a communication system may allow for an autonomous user equipment handover operation in a licensed or unlicensed spectrum. A method may include receiving a measurement condition at a user equipment. The measurement condition may include a maximum duration of time for sending a message to a base station of a source cell. The message may inform the base station of the source cell that an autonomous handover is initiated. The method may also include initiating the sending of the message to the base station of the source cell during the duration of time Tamer to indicate of the measurement condition. In addition, the method may include commencing the autonomous handover after the duration of time of the measurement condition has expired or upon successful transmission of the message to the base station of the source cell.
