Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control signal indicating a resource allocation for either an uplink transmission or a downlink transmission. The UE may identify, based at least in part on a modulation and coding scheme indicated in the control signal, an aggregation factor of the uplink transmission or the downlink transmission. The UE may communicate with the base station by either transmitting the uplink transmission or receiving the downlink transmission in accordance with the resource allocation and the aggregation factor.

The present invention is designed to suitably reduce the degradation of spectral efficiency even when communication is performed using a waveform of a single-carrier transmission scheme. According to one aspect of the present invention, a user terminal has a receiving section that receives a downlink control signal, which schedules transmission of a data signal in accordance with a waveform that is based on a single-carrier transmission scheme, and a transmission section that transmits a sounding reference signal, which is different from an uplink sounding reference signal used in existing LTE and which has a wider transmission bandwidth than the data signal, by using the waveform based on the single-carrier transmission scheme.

An example method may include identifying a first transmit identifier (TID) associated with a first node of a wireless network as ready to transmit and adding the first TID to a ready to transmit queue at a first point in time. The method may also include identifying a second TID associated with a second node of the wireless network as ready to transmit, and adding the second TID to the ready to transmit queue at a second point in time later than the first point in time. The method may additionally include selecting the second TID from the ready to transmit queue before selecting the first TID based on a projected increased overall throughput of packets within the wireless network when communicating with the second node before communicating with the first node.

A system that incorporates the subject disclosure may perform, for example, a method that determines at least one threshold for detecting signal interference in a first plurality of segments occurring in a first radio frequency spectrum of a first wireless communication system, detecting a pattern of recurrence over time of signal interference in a segment of the first plurality of resource blocks according to the at least one threshold, and performing one or more mitigation steps to mitigate the signal interference without filtering the signal interference where the one or more mitigation steps include at least one of transmitting signals out of phase from the signal interference, adjusting transmit power, increasing power in a resource block of a long term evolution communication session, performing beam steering, or changing time parameters for the resource block without changing to a new resource block. Other embodiments are disclosed.

A communication system is disclosed in which a base station manages the transmission of on-demand system information to optimise the trade-off between the additional signalling overhead associated with on-demand transmission and the resource usage inefficiencies associated with the sometimes unnecessary transmission of system information on a periodic basis. The base station manages switching from on-demand transmission to periodic transmission, and vice versa, based on one or more utilisation thresholds.
