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 method and a receiver device are disclosed for channel estimation of a broadcast channel. According to an embodiment, the receiver device determines a first channel estimation of demodulation reference signal (DMRS) from a transmitter device. The receiver device determines a second channel estimation of one or more synchronization related reference signals from the transmitter device. The receiver device determines a final channel estimation of a broadcast channel from the transmitter device based at least on the first and second channel estimations.

Method and receiver device for channel estimation of broadcast channel

Embodiments of the present disclosure relate to methods and devices for broadcast signaling transmission. In example embodiments, the network device transmits first broadcast signaling in a first time duration of a first transmission window within a first transmission period. The network device then communicates with a terminal device in a broadcasting gap between the first time duration and a second time duration of the first transmission window subsequent to the first time duration. Further, the network device transmits the first broadcast signaling in the second time duration. In this way, the interruptions caused by the long-time period reserved for the broadcast signaling transmission may be reduced.

Methods and devices for broadcast signaling transmission

This disclosure pertains to a method for operating a network node () in a radio access network. The method comprises transmitting synchronisation signaling, the synchronisation signaling comprising a signaling sequence, the signaling sequence being determined as a combination of a number of sub-sequences, wherein an order of the sub-sequences is mapped to synchronisation information. The disclosure also pertains to related devices and methods.

Method to implicitly indicate system information in NR

The present disclosure relates to a method used in a terminal device for performing random access to a network device, and the associated terminal device. The method comprises: obtaining access related information from a predefined Minimum Common Entry Set (MCES) stored in the terminal device; and performing random access to the network device based on the access related information.

Method for performing random access, and associated terminal device

Embodiments of the disclosure generally relate to transmission of access information. A network device generates an occurrence indication for indicating a subsequent occurrence of access information. Then, the network device transmits the occurrence indication in association with a system signature. The system signature indicates a part of the access information for use by a terminal device in accessing the network device. The power consumption of the terminal device in receiving the access information based on the occurrence indication can be reduced efficiently.

Method and device for facilitating transmission of access information

The embodiments disclose a method for an access node of a region from a plurality of regions in a cellular network to control access to the cellular network, the method comprising generating an access information table (AIT); sending the AIT to a plurality of communication devices, sending a first signature sequence; and sending a second signature sequence. The embodiments also disclose a method for a communication device to access cellular network, the method comprising detecting one or more of first signature sequences; selecting a first signature sequence; determining a region according to the selected first signature sequence; selecting an AIT, detecting a second signature sequence; determining an entry of the selected AIT according to the detected second signature sequence; and accessing the cellular network. The access node and communication device thereof are also disclosed according to the embodiments.

Access information table region for access to cellular networks

A wireless communication device and method therein for time synchronization in a wireless communication network are disclosed. The wireless communication device determines a first timing (tc) by performing a coarse time synchronization based on a synchronization signal received by the wireless communication device, wherein the received synchronization signal is sampled either in an original sampling rate or a reduced sampling rate. The wireless communication device determines a second timing (tf) by performing a fine time synchronization based on the determined first timing (tc) and the received synchronization signal.
