An origination device (e.g., a base station) receives relaying information from a signal forwarding device in a grant or a broadcast message. The relaying information can be information pertaining to channel conditions and/or quality (e.g., a Channel Quality Indicator) of a first communication link between the signal forwarding device and a destination device, and/or an encoding rate based on channel conditions associated with the first communication link. The origination device utilizes the relaying information to determine a first set of encoding parameters that correspond to channel conditions associated with the first communication link between the signal forwarding device and a destination device. The origination device encodes a first set of data according to the first set of encoding parameters and transmits the encoded first set of data to the signal forwarding device. The signal forwarding device transmits the encoded first set of data to the destination device.

The present disclosure relates to a method for activating a relay functionality of a ProSe capable and relay-capable user equipment within a mobile communication network. The radio base station, to which the relay UE is connected, determines whether further relays are necessary in the radio cell controlled by the radio base station. In case further relays are necessary in the radio cell, the radio base station selects a persistence check value and transmits a broadcast message in the radio cell. The broadcast message at least indicates that further relays are necessary and comprises the selected persistence check value. Upon receiving the broadcast message, the relay UE activates its relay functionality in case it determines that relay requirements for activating its relay functionality in the radio cell are fulfilled and in case a persistence check performed by the relay UE based on the received persistence check value is successful.

A method for performing monitoring, commissioning, upgrading, analyzing, load balancing, remediating, and optimizing the operation, control, and maintenance of a plurality of remotely located RF signal repeater devices in a wireless network arranged to operate as an Internet of Things (IoT) network. Electronic RF signal repeater devices are employed as elements in the wireless network and communicate wireless radio frequency (RF) signals for a plurality of users. An RF signal repeater device may be arranged to operate as a donor unit device that provides RF signal communication between one or more remotely located wireless base stations, or other donor unit devices on the wireless network. Also, an RF signal repeater device may be arranged to operate as a service unit device that provides wireless RF signal communication between one or more user equipment devices (UEs) and a donor unit device or a wireless base station.

An access method and a device are provided. The access method is applied to a first wireless backhaul node and includes: determining a previous hop node of the first wireless backhaul node, the previous hop node being a home donor base station of the first wireless backhaul node or being a second wireless backhaul node; and transmitting first information to the home donor base station directly or transmitting the first information to the home donor base station via the second wireless backhaul node.

Methods, systems, and devices for wireless communications are described. An assistive node may include circuitry for operating in an amplifying mode and operating in a reflecting mode. The assistive node may transmit a message to a network entity indicating that the assistive node is capable of operating in an amplifying mode or a reflecting mode. The network entity may transmit scheduling information to the assistive node for a packet transmission to be reflected or amplified by the assistive node to a wireless device, for example, because a direct path between the network entity and the wireless device is blocked. The network entity may transmit control signaling to the assistive node configuring the assistive node to either reflect or amplify the packet transmission to the wireless device. The assistive node may reflect or amplify the packet transmission to the wireless device based on the control signaling.

Provided are a method and an apparatus for transmitting downlink control information in a wireless communication system configured with a plurality of serving cells. The method generates downlink control information scheduling frequency division duplex (FDD) cells by means of FDD frames (DCI_FDD) and downlink control information scheduling time division duplex (TDD) cells by means of TDD frames (DCI_TDD), and transmits the DCI_FDD and the DCI_TDD, wherein parts of the fields of DCI_FDD and DCI_TDD are generated to have equal bit sizes, and if the FDD or TDD cell is used exclusively, then said parts of the fields in the FDD and TDD cells have mutually different bit sizes.

A method for data transmission includes: if correctly receiving one or more source data packets, a destination node selecting source data packets which have not been saved from the source data packets to save; if receiving one or more network coded data packets, the destination node decoding them, and if the decoding can be correctly conducted and source data packets can be obtained, the destination node selecting source data packets which have not been saved from obtained source data packets to save; if judging that the number of currently saved source data packets is greater than one, the destination node selecting and sending one saved source data to other destination nodes, or after conducting network coding according to part or all of saved source data packets to obtain one or more network coded data packets, the destination node selecting and sending one network coded data packet to other destination nodes.

A method of selectively enabling one of a first and a second operating mode in a first network device is presented. The first network device has a wireless receiver and transmitter for providing bi-directional communication with a mobile station through a first wireless link, for providing access to a network. In the first operating mode the wireless transmitter is not continuously enabled, and in the second operating mode the wireless transmitter is continuously enabled. In the first operating mode the first network device, receives, from a second network device, status information about a second wireless link maintained between the second network device and the mobile station, and sends, at predetermined time intervals, probe requests to the mobile station. The wireless transmitter is enabled for sending the probe request and disabled thereafter. The first network device receives a response to the probe request from the mobile station and determines a spatial distance of the mobile station to the first network device and to the second network device. Depending on the determined distance the first network device switches to the second operating mode, allowing association of the mobile station with the first network device via the first wireless link.

An aspect of this disclosure relates to a relay node, and a method of wireless communications by the relay node, including attempting to decode first code block groups of a transport block received in a resource allocation and according to a first encoding configuration. The aspects include identifying a symbol in the resource allocation that includes both of a first part of a successfully decoded one, and a first part of an unsuccessfully decoded one, of the plurality of first code block groups, and determining a modified transmit configuration for the symbol. Further, the aspects include encoding a second part of the successfully decoded one according to the first encoding configuration to define a second code block group that is outside of the symbol. Additionally, the aspects include transmitting the transport block including the one or more second code block groups and the symbol according to the modified transmit configuration.

A target communication line defined as a congestion determination target and a client that transmits an ACK signal to a communication partner in a case where a signal is received from the communication partner are relayed to each other. It is determined whether a congestion occurs on a target communication line. A communication of the ACK signal is limited by a capture process that captures the signal communicated by the client in a case where determining that the congestion occurs on the target communication line.
