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

According to some embodiments, a method is performed by a wireless device. The method comprises obtaining a data channel transmit power for transmitting on a sidelink data channel to a receiving wireless device, obtaining a control channel transmit power for transmitting on a sidelink control channel, and transmitting on the sidelink data channel at the data channel transmit power and on the sidelink control channel at the control channel transmit power. In certain embodiments, the control channel transmit power is based on the data channel transmit power. In other embodiments, the control channel transmit power is determined independently of the data channel transmit power.

Power control for the sidelink control channel

A method, system and apparatus are disclosed. A first wireless device is provided. The first wireless device includes processing circuitry configured to: determine first beam information based at least in part on second beam information received from a second wireless device via device-to-device communications where the first beam information indicates a first beam selected by the first wireless device for downlink wireless communications, and where the second beam information indicates a second beam selected by the second wireless device for downlink wireless communications; and cause transmission of the first beam information for grid of beams precoder determination.

Overhead reduction in frequency division duplexing (FDD) multiple-input multiple-output (MIMO)

A radio device receives first sidelink control information from a further radio device. Based on assistance information stored in the radio device and the received first sidelink control information, the radio device determines a configuration for transmission of second sidelink control information. Based on the determined configuration for transmission of the second sidelink control information, the radio device receives the second sidelink control information from the further radio device. Based on the received second sidelink control information, the radio device receives a sidelink radio transmission from the further radio device.

Multi-stage sidelink control information

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.

Control information exchange for control of D2D communication A first D2D communication device () receives first information from one or more second D2D communication devices (). The first information indicates control information for one or more links from the respective second D2D communication device (). Based on the indicated control information, the first D2D communication device () determines control information for one or more links from the first D2D communication device ().

Control information exchange for control of D2D communication

Power control for a bidirectional Sidelink (SL) is provided. Solutions proposed herein limit the Physical SL Feedback Channel (PSFCH) transmit power level to that of the power level used for Physical SL Shared Channel (PSSCH) so as to prohibit too high transmit power for the PSFCH. In addition, if the difference between the PSSCH and PSFCH exceeds a preconfigured threshold (e.g., the PSFCH is too low), a Receiver (Rx) User Equipment (UE) can take preventive actions that ensure sufficient quality over the PSFCH. In further embodiments, both UEs continuously maintain the estimated SL Path Loss (PL) and transmit a single SL Channel State Information Reference Signal (SCSI-RS), and associated measurement reports rather than triggering new SCSI-RS transmissions and measurement reports for each PSSCH and associated PSFCH channel per SL (e.g., PC5) connection.

Power control for bidirectional sidelink

A technique for transmitting and receiving data in a radio communication from a second radio device to a first radio device is described. As to a method aspect of the technique, one or more radio resources are determined based on radio signals received at the first radio device. The one or more radio resources comprise at least one spatial stream among different spatial streams receivable at the first radio device. A status message indicative of the one or more determined radio resources is transmitted to the second radio device. The data from the second radio device is received at the first radio device on at least one radio resource depending on the one or more radio resources indicated in the transmitted status message.

Technique for device-to-device communication based on radio signals received from one or more radio sources

A method, system and apparatus are disclosed. A network node configured to communicate with a wireless device is provided. The network node configured to, and/or comprising a radio interface and/or comprising processing circuitry configured to receive a unicast request message from a wireless device where the unicast request message includes information associated with a request for a unicast connection, and determine whether to permit establishment of the requested unicast connection based at least in part on the information in the unicast request message.

Method for resource allocation in device to device communication

A method, wireless device, and network node configured to enable a wireless device to serve as a base station to at least one other wireless device in a communications network, the wireless device being configured to perform predetermined base station functions. The method includes determining a condition triggering a need to provide the predetermined base station functions to the at least one other wireless device, notifying a network node in the communications network that the wireless device is available to provide the predetermined base station functions, receiving approval from the network node to provide the predetermined base station functions, and providing the predetermined base station functions to the at least one other wireless device.

Cellular service improvement and extension by user equipment

A radio device receives a first message from a further radio device. The first message indicates an intention of the further radio device to perform a device-to-device radio transmission on a set of radio resources. The radio device determines a status of the set of radio resources. In response to the first message, the radio device sends a second message comprising an indicator which indicates the determined status of the set of radio resources in terms of at least three levels.

Multi-level indicator of radio resource status for intended D2D transmission

A network node (), a wireless device () and methods therein, for handling interference in a wireless network where a Listen-Before-Talk, LBT, scheme is employed to control transmissions. The network node () determines whether a first wireless device () is compatible with a second wireless device () at a serving network node () so that uplink signals transmitted (A,A) from the wireless devices () are spatially separable at the serving network node (). An LBT-related message is then transmitted (A) to the first wireless device (), which message indicates that the wireless devices () are compatible or incompatible at the serving network node (). The second wireless device () is then able to detect (A), i.e. overhear, the LBT-related message and use it as a basis for deciding () whether to perform a transmission or not. The second wireless device () can thus decide to transmit when the compatibility information indicates that the wireless devices () are compatible, or refrain from transmission when the compatibility information indicates that the wireless devices () are incompatible.
