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.

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

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.

A system and method for providing phase noise-based signal design for positioning in a communication system. In one embodiment, an apparatus is configured to receive configuration parameters for a reference signal based on a level of phase noise for the reference signal estimated by a user equipment, apply the configuration parameters to the reference signal to obtain a modified reference signal, and transmit the modified reference signal to the user equipment to enable a position of the user equipment to be determined.

System and method for phase noise-based signal design for positioning in a communication system

A method, apparatus, and system are provided for facilitating positioning based on signal correlation function characteristic feedback. In an embodiment, the method may involve steps performed by a network node in communication with a wireless communication device (WCD) and a plurality of base stations. The network node receives, from the WCD, location information including position reference signal (PRS) correlation function characteristics of a cross-correlation between a received downlink signal and a transmitted PRS for each base station from the plurality of base stations. The network node determines a position of the WCD using the PRS correlation function characteristics. The WCD may initiate the transmission of the PRS correlation function characteristics on its own, or in response to a request to do so from the network node.

Methods and apparatuses for positioning based on signal correlation function characteristics feedback

Methods and apparatuses for determining a position of a wireless device in a wireless communication network are provided. The method includes obtaining a first sequence of Time Difference of Arrivals (TDOAs) at the wireless device of reference signals, which are transmitted by and used for synchronization of a first pair of network nodes; and determining, based on the first sequence of TDOAs, a first relative distance. The method also includes obtaining a second sequence of TDOAs at the wireless device of reference signals, which are transmitted by and used for synchronization of a second pair of network nodes; and determining, based on the first sequence of TDOAs, a second relative distance. The method further includes determining the position of the wireless device based on the first and second relative distances. Corresponding computer programs and computer program carriers are also disclosed.

Method, apparatus and system for determining a position of a wireless device

Methods and devices for performing hybrid fingerprinting/observed time difference of arrival (OTDOA) positioning are described. Fingerprinting information can be used to improve OTDOA results by using the fingerprinting information to generate OTDOA assistance information. The OTDOA assistance information is sent to a user equipment, which uses the OTDOA assistance information to perform reference signal time differences (RSTDs) measurements.

Hybrid fingerprinting/OTDOA positioning techniques and systems

A Radio Network Node (RNN) and a method for enabling an improved reception of Positioning Reference Signals (PRSs) at a communications device. The RNN and the communications device are operable in a wireless communications network. The RNN selects a first precoder and a second precoder for forming a first beam and a second beam, respectively, and obtains a precoding switching pattern relating to when the first precoder is to be applied to one or more first PRS symbols and when the second precoder is to be applied to one or more second PRS symbols. Further, the RNN transmits, to the communications device, the one or more first PRS symbols to which the first precoder is applied; and in accordance with the obtained precoding switching pattern, the RNN transmits, to the communications device, the one or more second PRS symbols to which the second precoder is applied.

Methods for improved reception of positioning reference signals

A method and a receiving node for determining Time Of Arrival (TOA) for a radio signal received from a transmitting node in a wireless network. The receiving node detects the received radio signal by cross-correlating the received radio signal with a predefined reference signal transmitted by the transmitting node, to obtain a Cross-Correlated Function (CCF). The receiving node then estimates a set of candidate TOAs for respective signal components of the cross-correlated signal, and determines a final TOA for the received radio signal based on the set of candidate TOAs.

Systems and methods relating to a remote wireless device for a cellular communications network are disclosed. In some embodiments, the remote wireless device is a wireless device that desires to establish a relay connection with a relay wireless device that has relay functionality. The remote wireless device includes a transceiver, a processor, and memory storing instructions executable by the processor whereby the relay wireless device is operable to rank a plurality of candidate relay wireless devices and to report a subset of the plurality of candidate relay wireless devices based on the ranking of the plurality of candidate relay wireless devices to a network node of the cellular communications network via the transceiver.
