摘要： Methods for facilitating random access between a network node and a terminal device are disclosed. One method includes transmitting to a terminal device access configuration information required for the terminal device to receive a first random access message from a network node. The method further includes transmitting the first random access message to the terminal device based on the access configuration information.

摘要： A radio node (52) in a wireless communication system (10) employs multiple different candidate formats (22) that define different possible positions of decoding checks (24) within a transport block of a specific size. The radio node (52) determines, from these different candidate formats (22), a format that defines a position of decoding checks (24) within a transport block (16) to be encoded or decoded. The radio node (52) then encodes or decodes at least a portion of the transport block (16) based on the determined format.

摘要： Embodiments described herein provide a method in a network node for configuring interference measurements for a wireless device. According to the method, the network node receives information indicating whether a channel state information interference measurement (CSI-IM) resource configuration restriction applies for the wireless device. The network node further configures CSI-IM resources for the wireless device based on the information.

摘要： A node (100) of a wireless communication network receives a synchronization signal from a radio device (10). Based on the received synchronization signal, the node determines a time alignment configuration for uplink radio transmissions from the radio device to the wireless communication network. Based on the received synchronization signal, the node further determines Hybrid Automatic Repeat Request feedback information for at least one downlink radio transmission from the wireless communication network to the radio device (10). The node (100) indicates the determined time alignment configuration to the radio device (10). Based on the determined Hybrid Automatic Repeat Request feedback information, the node controls retransmission of the at least one downlink radio transmission.

摘要： A cellular network supports radio communication based on a first configuration which organizes a time-frequency space in first resource elements and radio communication based on a second configuration which organizes the time-frequency space in second resource elements and assigns at least one of the second resource elements to a utilization which is in conflict with the radio communication based on the first configuration. A node of the cellular network sends an indication to a communication device. The indication comprises time domain and/or frequency domain information for defining a pattern comprising at least one of the first resource elements which is to be disregarded by the communication device when performing radio communication with the cellular network based on the first configuration and/or the second configuration. The at least one first resource element of the pattern defines a first part of the time-frequency space which overlaps a second part of the time-frequency space defined by the at least one of the second resource elements.

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 do, signaling overhead and energy consumption within the wireless device (16) when operating in the long range extension mode is substantially reduced.

摘要： A method and a first node for handling a feedback procedure requiring transmission of feedback messages indicating either an acknowledgement, ACK, or a non-acknowledgement, NACK, of correct reception of data transmitted on a forward link in a radio communication with a second node in a radio network. The first node obtains a latency requirement of the radio communication corresponding to the time from transmission of the data until the data becomes outdated. The first node further applies a first transmission mode employing said feedback procedure when the latency requirement is above a latency threshold, and applies a second transmission mode omitting said feed back procedure when the latency requirement is below the latency threshold.

摘要： The present disclosure provides methods and apparatus for a wireless communications network in which system information can be provided on an efficient basis to mobile devices in the network. The system information is split into two parts, with the second part being transmitted to mobile devices in response to receipt of one or more request signals from those mobile devices. The second system information part may additionally be broadcast.

摘要： Some embodiments herein relate to method in a user equipment for determining a transmit power to be used by the user equipment when transmitting in a radio communications network, which user equipment is served by a radio network node in the radio communications network. The user equipment receives, from the radio network node, an indication indicating a set of power control parameters out of multiple sets of power control parameters, which multiple sets of power control parameters are stored at the user equipment. The user equipment determines a transmit power based on the indicated set of power control parameters.

摘要： A base station, in a wireless communications system, configures first resources for data access from devices to said base station, said first resources allowing a cyclic prefix having a first length; and configures second resources for data access from devices to said base station, said second resources allowing a cyclic prefix having a second length longer than the first (a) length. The base station transmits configuration information regarding the configured resources to at least one device. The first resources allow at least data having a first data period and a cyclic prefix having the first length to be received in a first period having a first predetermined duration; and the second resources allow at least data having a second data period and a cyclic prefix having the second length to be received in a second period having the second predetermined duration, and the second predetermined duration is an integer multiple of the first predetermined duration.
