摘要： A wireless device is configured with or allocated two or more control resource sets for receiving downlink control information from a base station or cell. The two or more control resource sets correspond to two or more possible states of a time slot used for downlink transmission. The wireless device determines the state of a time slot and selects one or the two or more control channel resource sets to monitor for DCI depending on the state of the time slot. In one exemplary embodiment, the time slot has two possible states and the state of the time slot is determined by the presence or absence of an SS block.

摘要： The present disclosure relates to a wireless device and a method, for use in a wireless device, for controlling discontinuous reception, DRX, during idle mode. The method comprises selecting (S31) a default DRX cycle pattern for controlling operative instants during a DRX cycle and receiving (S32) from an access node, a first set of beams in the operative instants of the default DRX cycle pattern. The method further comprises determining (S33) reception quality metrics for respective beams and determining (S34), based on the reception quality metrics, a customized DRX cycle pattern for controlling operative instants during a subsequent DRX cycle. The customized DRX cycle pattern is applied (S35) in the subsequent DRX cycle to receive a second set of beams.

摘要： A wireless communication device (140) and method therein for managing connection states in a wireless communication system (100) are disclosed. The wireless communication device (140) comprises at least two Subscriber Identity Modules, SIMs, in which a first SIM is associated to a first original connection state towards a first network node (111), a second SIM is associated to a second original connection state towards a second network node (121). The wireless communication device (140) obtains a position of the wireless communication device (140) and determines a priority list for the at least two SIMs based on the obtained position. The wireless communication device (140) further determines whether the respective connection states of the first and second SIMs have conflicting needs in radio resources. When the respective connection states of the first and second SIMs have conflicting needs in radio resources, the wireless communication device (140) performs a connection state change for the SIM that has lower priority from its original connection state to a third connection state.

摘要： A radio network device, having a narrowband receiver and operative in a wireless communication network, exploits the periodicity of transmission of network sync signals by iteratively receiving a plurality of frequency-offset portions of the sync signal, and then assembling the portions to recreate the entire sync signal. The recreated sync signal is then processed to attempt network detection and synchronization. In some embodiments, frequency/time compensation may be applied to the received and stored sync signal portions, prior to their combination, to compensate for uncertainty in the frequency drift (and time drift due to frequency error) of the sync signal location.

摘要： A network sync signal with unknown frequency location is detected by sampling the received signal over a band of interest in frequency, and over the repetition period of the sync signal in time. The signal is converted to the frequency domain. Sub-bands of the frequency-domain signal, corresponding to different possible sync locations and frequency offsets, are extracted and converted to the time domain, where the sync signal is searched over the reception window length using time-domain matched filtering.

摘要： Systems and methods for transmission and reception of a wake-up signal having a determined maximum length that is related to a maximum repetition value of another signal are disclosed. Embodiments of a method in a wireless device for determining a maximum length of a wake-up signal representing a maximum duration of the wake-up signal, the WUSmax value being related to a maximum repetition value representing a maximum number of repetitions of signals transmitted by a network node in a cellular communications network are disclosed. In some embodiments, the method in the wireless device includes receiving a Rmax value from the network node, determining a WUSmax value based on the Rmax value, and attempting to detect a wake-up signal from the network node using the determined WUSmax value.

摘要： A transmission allocation method is disclosed for a network node of a wireless communication system configured to communicate using an Orthogonal Frequency Division Multiplexing (OFDM) signal comprising sub-carriers in a frequency domain and a symbols in a time domain. The network node is associated with a network node bandwidth comprising a network node direct current (DC) sub-carrier. The network node is configured to communicate with a wireless communication device (WCD) associated with a WCD bandwidth comprising a WCD DC sub-carrier which is different from the network node DC sub-carrier. The method comprises acquiring, in relation to an upcoming communication between the network node and the WCD, at least one of an indication of a receiver DC frequency and an indication of a transmitter DC frequency, determining a transmission allocation for the upcoming communication based on the acquired indication(s), and performing communication based on the transmission allocation.
