摘要： The present disclosure relates to methods and devices for synchronizing one or more radio devices with a radio access node. A method of providing synchronization with a radio access node for radio communication to one or more radio devices is disclosed. The method comprises or triggers transmitting a configuration message to at least one of the radio devices, where the configuration message is indicative of a synchronization signal configuration for a configurable synchronization signal. The method further comprises or triggers transmitting the configurable synchronization signal to the at least one radio device in accordance with the synchronization signal configuration and communicating one or more decodable signals between the radio access node and the at least one radio device using radio resources in accordance with the configurable synchronization signal. A corresponding method of synchronizing the radio device with the radio access node for radio communication is disclosed.

摘要： Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

摘要： There is provided network node (110, 550) for handling communication of wireless devices (121, 650) in a wireless communication network (100). The network node comprises processing circuitry (551) configured to send a first configuration message to a wireless device, wherein the first configuration message comprises a resource reservation scheme. The resource reservation scheme comprises at least one bitmap indicating at least one reserved resource, wherein the at least one bitmap indicates reserved resources within a subframe, and wherein resources carrying a predefined reference signal have been excluded from the bitmap. There is also provided a corresponding wireless device (121, 650) for communicating with a network node (110, 550) in a wireless communication network (100), and corresponding methods performed by a network node and a wireless device.

摘要： In one aspect, a network device transmits using a first carrier having a predetermined number of subcarriers within the bandwidth of a second carrier, such that data for one or more of the predetermined number of subcarriers corresponding to a partial overlap by the first carrier of a resource block of the second carrier is not transmitted. In another aspect, the wireless device receives using a first carrier having a predetermined number of subcarriers within the bandwidth of a second carrier, such that one or more of the predetermined number of subcarriers corresponding to a partial overlap by the first carrier of a resource block of the second carrier are discarded when decoding the received signal.

摘要： Systems and methods for decoding a transmission are provided. In some embodiments, a method performed by a wireless device comprises determining a plurality of Machine-Type Communications (MTC) Physical Downlink Control Channel (MPDCCH) transmission candidates to monitor. For at least one candidate of the plurality of MPDCCH transmission candidates, the method includes determining whether the candidate belongs to a first group of candidates or a second group of candidates. If the candidate belongs to the first group of candidates, the method includes attempting to decode the MPDCCH transmission using a Channel State Information (CSI)-based precoding scheme. If the candidate belongs to the second group of candidates, the method includes attempting to decode the MPDCCH transmission using a predetermined precoding scheme. This may allow a more robust precoding technique and can be considered as technique with a fallback solution for the cases in which the CSI is either missed or not reliable.

摘要： Enabling a UE to determine whether the UE can skip the acquisition of SIB1-BR. An indication (e.g., a one bit flag) in the MIB is provided, which indication is set to a particular value if the UE needs to read SIB1-BR, otherwise the indication is set to a different value indicating that the UE can skip reading SIB1-BR assuming other conditions are met (e.g., assuming that the UE has previously read SIB1-BR within a MIB indication time period).

摘要： Systems and methods are disclosed for adjusting Radio Link Monitoring (RLM), Radio Link Failure (RLF) detection, RLF recovery, and/or connection establishment failure detection for wireless devices (16) in a cellular communications network (10) depending on mode of operation. In one embodiment, a node (14, 16) in the cellular communications network (10) determines whether a wireless device (16) (e.g., a Machine Type Communication (MTC) device) is to operate in a long range extension mode of operation or a normal mode of operation. The node (14, 16) then applies different values for at least one parameter depending on whether the wireless device (16) is to operate in the long range extension mode or the normal mode. The at least one parameter includes one or more RLM parameters, one or more RLF detection parameters, and/or one or more RLF recovery parameters. In doing so, signaling overhead and energy consumption within the wireless device (16) when operating in the long range extension mode is substantially reduced.

摘要： According to some embodiments, a user equipment (UE) and a method in the UE are disclosed. The UE is served by a cell managed or served by a network node. The UE comprises processing circuitry, a transceiver coupled to the processing circuitry, and memory containing instructions executable by the processing circuitry. The UE is operative to determine that a center frequency of a radio frequency (RF) reception bandwidth of the UE is different than a center frequency of a RF transmission bandwidth of the cell serving the UE. The UE is further operative to receive a signal from the cell serving the UE over a center subcarrier within the RF reception bandwidth of the UE, and puncture a portion of the signal received over the center subcarrier within the RF reception bandwidth of the UE.
