摘要： Systems and methods are disclosed for triggering a long range extension mode of operation for a wireless device in a cellular communications network. In one preferred embodiment, the wireless device is a Machine Type Communication (MTC) device. In one embodiment, a node in the cellular communications network determines that the wireless device is to operate in the long range extension mode if there is difficulty in establishing communication between the wireless device and the cellular communications network. If the wireless device is to operate in the long range extension mode, the node activates one or more long range extension mechanisms with respect to the wireless device such that the wireless device operates in the long range extension mode. In this manner, the long range extension mode is selectively triggered for the wireless device.

摘要： Embodiments herein relate to, e.g., a method performed by a communication node for controlling one or more communication parameters of a channel between a first communication device and a second communication device in a wireless communication network. The communication node, upon obtaining an indication of a channel quality of the channel to the second communication device, uses a correction value and the indication when determining the one or more communication parameters. The correction value is based on a decoding success of one or more previous transmissions, which one or more previous transmissions are based on an obtained previous indication of a previous channel quality from the second communication device, and wherein a change of the correction value relative a previous correction value is limited.

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： A radio device (100) sends a radio transmission (503, 507) to a further radio device (150). Further, the radio device (100) receives a further radio transmission (505, 509) from the further radio device (150). The further radio transmission (505, 509) comprises an indicator of reception success. In response to the indicator being toggled with respect to a previous state of the indicator, the radio device (100) determines that the radio transmission (509) was successfully received by the further radio device (150). In response to the indicator not being toggled with respect to the previous state of the indicator, the radio device (100) determines that the radio transmission (503) failed.

摘要： Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.
