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

Embodiments include methods for a network node of a 3GPP RAN. Such methods include determining a configuration that enables a UE to steer the UE's traffic between the 3GPP RAN and a WLAN without receiving a traffic steering command from the 3GPP RAN. The configuration includes a forward traffic steering configuration comprising a first plurality of thresholds/conditions for which the UE, when connected to 3GPP RAN, can initiate steering at least some of the UE's traffic from 3GPP RAN to WLAN; and a backward traffic steering configuration comprising a second plurality of thresholds/conditions for which the UE, when connected to WLAN, can initiate steering at least some of the UE's traffic from WLAN to 3GPP RAN. The backward traffic steering configuration includes threshold(s)/condition(s) based on different values of a same parameter as threshold(s)/condition(s) of the forward traffic steering configuration. The configuration is sent to the UE in a single message.

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.

The network node obtains the at least two patterns. Each of the at least two patterns is associated with information about a respective restricted area such that each pattern is used when a user equipment served by the cell is located in the respective restricted area. Each respective restricted area is smaller than an entire area of the cell. Moreover, a method and a user equipment for configuring measurements are provided. The user equipment is served by a cell of a radio base station. The user equipment receives at least two measurement patterns from the radio base station. Each measurement pattern is associated with a respective restricted area. Each respective restricted area is smaller than an entire area of the cell.

The present disclosure relates to the field of wireless communication, and in particular to a method and arrangement for improving flow control interaction in a low latency distributed radio access network, RAN, including an upper layer RAN node and at least one lower layer RAN node.

The present invention provides a muting configuration for reference signal (RS) transmission as a pattern defined by at least the combination of a muting sequence and a reference point. Muting occasions for a given wireless communication network cell () thus are differentiated from another cell by use of a different muting sequence, a different reference point, or both. Moreover, in one or more embodiments, the present invention provides for the use of a common muting sequence or reference point across cells (), with muting occasions being differentiated between cells () through use of different reference points (in the case of a common muting sequence), or through use of different muting sequences (in the case of a common reference point), or different sequences and different reference points. Such arrangements simplify the signaling needed to control or indicate the muting configuration in use in the cells of interest, provide an advantageous basis for propagating muting configurations among cells (), eliminate the need for predefined muting configurations, and the need for blind detection of muting by wireless communication apparatuses (), such as UEs.

There is provided support mechanisms for at least one adding and removing a cell from operation in a heterogeneous radio network having a first type of basic cell for providing basic radio coverage and a second type of cell associated to a basic cell as a capacity enhancing cell. A capacity enhancing cell is selectively switched on and off. When the capacity enhancing cell is shut down the cell does not exist over the air while cell configuration information is kept. When the capacity enhancing cell is switched on the cell becomes available again over the air interface. An indication of shut-down and a wake-up call message for switch-on of the capacity enhancing cell are communicated between a base station serving the capacity enhancing cell and a base station serving the basic cell. In this way energy savings can be supported without disrupting service availability.
