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.

Network architecture, methods, and devices for a wireless communications network

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.

A first radio node (), a second radio node () and methods therein, for transmitting and receiving a data block in a radio network. The first radio node () selects () at least one of: 1) time diversity mode, 2) frequency diversity mode, and 3) spatial diversity mode, based on a first comparison between an estimated signal quality of each diversity mode and a quality threshold, and/or a second comparison between an estimated round trip time of each diversity mode and a round trip time threshold. The first radio node () further performs () a first transmission of the data block, and the second radio node () identifies () the diversity mode(s) selected by the first radio node (). The first radio node () then performs () a second transmission of the data block according to the selected diversity mode(s) so that the second radio node () can decode () the data block by combining the first and second transmissions of the data block.

First and second radio nodes and methods therein, for performing a radio communication

A technique for reporting events from a mobile device to a cellular network () is provided. The mobile device is wirelessly connectable to the cellular network (). As to a method aspect of the technique, records of the events are stored while the mobile device is out of network coverage. The stored records are reported to the cellular network () when the mobile device is wirelessly connected to the cellular network ().

A User Equipment, UE, operable to be used in a wireless communication network and a method performed by the UE for transmitting Sounding Reference Signals, SRSs are provided. The method comprises receiving () at least one transmission from at least one network node, and measuring () at least one radio quality indicator based on the received at least one transmission. The method further comprises comparing () the at least one measured radio quality indicator to at least a first threshold value; and transmitting, or refraining from transmitting, () SRSs based on a result of the comparison.

A method and network node () for determining an offset for selection of a cell of a first radio network node () is provided. The network node () comprises a processing circuit configured to determine the offset based on a first distance value for indicating distance between the first radio network node () and a second radio network node (). The network node () further comprises a transmitter configured to send information about the offset.

A base station (BS) and method for controlling handover in a wireless communication system. The BS serves a first cell in a first cell layer overlapping with a second cell layer, and the first cell has a different distribution of configured amounts of uplink and downlink resources than a second cell in the second cell layer. The BS monitors amounts of uplink and downlink resources utilized by a user equipment (UE) in the first cell and adjusts at least one parameter controlling handover of the UE to the second cell based on the resources utilized by the UE, and on information regarding configured amounts of uplink and downlink resources in the first and second cells. This increases the likelihood that the UE will be served by one of the first and second cells in which the configured amounts of resources better matches the amounts of resources utilized by the UE.

A method for cell selection comprises obtaining of user equipment specific information for a user equipment that is present in a first cell of a first base station. The user equipment specific information comprises information of a prevailing radio situation and information of a present decoding performance. A present capability of the user equipment for handling increased interference and a measure of a cell selection offset required to cover the user equipment by a second cell is estimated from the user equipment specific information. It is decided on modifying a cell selection offset for handover between the first cell and the second cell, in dependence on the estimated present capability of the user equipment for handling increased interference and the cell selection offset required to cover the user equipment by the second cell.

Cell selection in cellular communication systems

An interference problem for UE retransmissions at the end of a Sequence Frame Number pattern, in a system wherein a macro base station () employs Almost Blank Subframes (ABS) to avoid interference with a micro base station (), is avoided by first recognizing that an ABS pattern will reset at the end of a SFN period. In some embodiments, in response to this recognition, the micro base station () may command () a UE to alter a transmission to the micro base station (), to improve the probability of accurate reception&#x2014;such as by increasing its transmit power during the relevant time slots, or utilizing a more robust data correction encoding scheme. In other embodiments, in response to recognizing the change in the ABS pattern, the macro base station () may schedule () other UE to a PRB where they cause lower interference, or may avoid scheduling macro cell UEs in the same time slot.
