It is determined whether a first first resource among at least one first resource used for sending a random access preamble overlaps a first second resource among at least one second resource used for sending a first scheduling request on a predetermined time unit; if the resources overlap, the preamble is sent by means of a first resource that does not overlap with a second resource, and the first scheduling request is sent by means of a second resource that does not overlap with a first resource.

A communication device includes a transmitter that transmits data; and a controller that generates, in response to a predetermined trigger, a request signal including information on a time and frequency location of a radio resource to be used by the transmitter.

A method of coordinating positioning signaling includes: identifying a first user equipment (UE) served by a base station and a second UE served by the base station, the base station being configured to send a base station positioning signal wirelessly at a plurality of base-station-transmission times; allocating first times to the first UE, for sending first UE positioning signals, and second times to the second UE, for sending second UE positioning signals, at least one of the first times being different from at least one of the second times; sending a first communication to cause the first UE to send at least a respective one of the first UE positioning signals at each of the first times; and sending a second communication to cause the second UE to send at least a respective one of the second UE positioning signals at each of the second times.

Systems, methods, and instrumentalities are described herein that may be used for NOMA resource selection. Different types of NOMA resources may be configured by a network and selected by a WTRU based on rules, priorities, fairness, overloading factors, multiple access signature sizes, measurement results, payload sizes, and/or the like. Single-NOMA operations may be performed using DFT-invariant codewords. Multiple NOMA schemes may coexist with different codeword types and/or codeword sizes.

Methods, wireless devices and network nodes for avoiding collision between a downlink control channel and a aperiodic channel state information reference signal, aperiodic CSI-RS, are provided. According to some aspects, a method is provided that includes receiving an aperiodic channel state information reference signal, aperiodic CSI-RS, based on an assumption that the aperiodic CSI-RS is not present in physical layer resources corresponding to a downlink control channel set.

A wireless device includes a digital receiver configured to receive data via an antenna array, and to determine a load metric based on a load of subcarriers around reference subcarrier signals of a reference signal, and a controller configured to compare the load metric to a load threshold to determine whether the load of the subcarriers is less than a predefined level, and if the load of the subcarriers is less than the predefined level, identify at least one time point where the reference signal repeats itself during a symbol period, and control the antenna array to switch among the plurality of antenna beamforming patterns based on the at least one time point.

A method for detecting downlink control information includes receiving, by a terminal device from a network device, detection related information for detecting downlink control information (DCIs) of all bandwidth parts (BWPs), where the detection related information is determined by the network device based on resource load of control resource sets of all the BWPs, and detecting, by the terminal device, each of the DCIs based on the detection related information.

The disclosed subject matter relates to facilitating uplink communication waveform selection in wireless communication systems, and more particularly Fifth Generation (5G) wireless communication systems. In one or more embodiments, a system is provided comprising a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. These operations can comprise facilitating establishing a wireless communication link between a first device and a second network device of a wireless communication network, and determining a waveform filtering protocol for application by the first device in association with performance of uplink data transmissions from the first device to the second network device.

Embodiments are provided herein for improving carrier aggregation for wireless networks. A plurality of bandwidth channels are assigned to a basic service set (BSS) for transmissions. Specifically, the bandwidth channels are divided into multiple channel segments corresponding to multiple primary or alternate primary channels. A channel segment possibly further includes one or more additional secondary channels. The locations of the primary or alternate primary channels that correspond to the channel segments of the BSS are then broadcasted in the network. When a station or AP receives this BSS information, it searches for an available primary or alternate primary channel of the BSS to begin transmission. Upon detecting an available primary channel or alternate primary channel that is not used for another transmission, the station or AP transmits data on the channel segment corresponding to the detected primary or alternate primary channel.
