摘要： A method and a wireless device (110) for managing a set of resources for transmission of data to a further wireless device (120) using D2D communication are disclosed. The wireless device (110) and the further wireless device (120) are capable of being operated in a mixed cellular and D2D radio network (100). The set of resources are comprised in a cellular spectrum of the mixed cellular and D2D radio network (100). The wireless device (110) selects, from among the set of resources, a sub set of resources for the transmission of data according to a hopping algorithm for distribution of the sub set of resources among the set of resources. Then, the wireless device (110) sends a scheduling command to the further wireless device (120). The scheduling command indicates the selected sub set of resources. The wireless device (110) sends the data to the further wireless device (120) on the selected sub set of resources using D2D communication.

摘要： The invention relates to a method and an arrangement for reducing power consumption of a receiver in a mobile communication network comprising a sender transmitting packet data on a downlink channel to one or more receivers over a radio interface. Inactive time instants and listening time instants are defined according to provided rules. The receiver is arranged to listen for information from the sender during the listening time instants and to sleep during the inactive time instants. Thus, less power will be consumed during the inactive time instants.

摘要： Radio resources like spreading codes and transmission power are optimally allocated to various different types of radio channels supported in the cell including a specialized channel like a high-speed shared channel. One or more measurements made at the base station are provided to the radio resource manager. Such measurements include other-channel power, high speed shared channel code usage, high speed shared channel transport format usage, average active load on the high speed shared channel, empty buffer, excess power, and similar parameters that relate to a high speed shared channel. One or more of these reported measurements may then be used to access, allocate, and/or to regulate resources associated with the base station's cell.

摘要： The present invention generally relates to radio communication systems, relay nodes, controller nodes, user equipment (user terminals), software and methods for said systems and nodes. In one embodiment, a method for operating a control node for a wireless communication system is provided. The method comprises the steps: creating a data frame comprising an early part and a later part, wherein the early part comprises first control data for controlling a receiving node; checking whether second control data are to be put into the later part; scheduling payload data for the receiving node into the later part if second control data are not to be put into the later part; and transmitting the data frame to the receiving node.

摘要： The available transmission resources on a downlink-shared channel are divided into resource blocks, each resource block comprising a predetermined number of sub-carriers during a predetermined time period. The resource blocks are subdivided into localized resource blocks and distributed resource blocks. A user requiring sufficient resources can be allocated a plurality of said localized resource blocks. A user who would require only a small number of said localized resource blocks can instead be allocated subunits of a plurality of said distributed resource blocks.

摘要： The present disclosure relates to random access in wireless communication systems, and in particular to a wireless device, a preamble receiver, and methods for processing random access preamble signals. A disclosed method in a wireless device comprises generating (S11) one or more identical short sequences having a same time duration as an OFDM symbol used for carrying data traffic in a radio access network of the wireless device. The method also comprises generating (S12) at least one offset indicator sequence different from each of the short sequences, and constructing (S13) the preamble sequence by concatenating the at least one offset indicator sequence and the one or more identical short sequences in time, such that each of the at least one offset indicator sequence has a respective pre-determined location in the preamble sequence.

摘要： Systems and methods are disclosed for using multiple configuration groups having corresponding configuration identity (CID) parameters to configure a transmission channel and a reception channel for a user equipment device in a cellular communication network. In one embodiment, a user equipment device in a cellular communication network obtains CID values for CID parameters for a number of configuration groups. Each of the configuration groups includes one or more transmission channel or reception channel parameters. For each of the configuration groups, the user equipment device configures the parameters in the configuration group based on the CID value obtained for the CID parameter for the configuration group. In this manner, the transmission channel and the reception channel for the user equipment device are configured based on multiple CID values rather than a single physical layer cell identifier for a cell in which the user equipment device is located.

摘要： A first user equipment transmits a beacon signal to be detected by at least one second user equipment for Device-to-Device, D2D, communication in a wireless telecommunications network. The first user equipment transmits the beacon signal in transmission bursts with a first energy level, where the transmission bursts are transmitted continually over time in order to enable detection of the beacon signal by the at least one second user equipment. The first user equipment then increases the energy of the transmission bursts at one or more intervals to a second energy level such that transmission bursts with the first energy level is alternated with transmission bursts with the second energy level, and such that transmission bursts with the first energy level recur more frequently over time than transmission bursts with a second energy level. A user equipment, a network node and a method in the network node are also provided.

摘要： A method in a wireless device for performing random access to a network node. The method comprises receiving a set of downlink beam-specific reference signals, BRS, from the network node, and determining a preferred BRS based on the received signal power for each BRS. The method also comprises selecting, based on the preferred BRS, a random-access resource to be used for transmitting a random-access attempt to the network node, as well as using the selected random-access resource when transmitting a random-access attempt to the network node, whereby the selection of random-access resource indicates to the network node which downlink beam is preferred by the wireless device to be used for downlink transmissions.

摘要： The present disclosure relates to random access in wireless communication systems, and in particular to transmitting, receiving, and detecting preamble sequences. A method in a wireless device for transmitting a preamble sequence to a network node is disclosed. The method comprises configuring a number of preamble sequences into two or more preamble sets, wherein each preamble set is associated with at least one respective uplink transmission condition; determining a transmission condition of an uplink from the wireless device to the network node; and selecting one out of the two or more preamble sets based on the determined transmission condition to be a selected preamble set, and a preamble sequence from the selected preamble set to be a selected preamble sequence; as well as transmitting the selected preamble sequence on the uplink.
