Described are devices, systems and methods for scheduling multi-user (MU) multiple input multiple output (MIMO) transmissions in a fixed wireless access (FWA) system. One method for scheduling a large number of user devices in a wireless communication system includes a preselection process to pare down the number of user devices to be simultaneously scheduled, and then scheduling that subset of users. In an example, and assuming each user device communicates over a corresponding wireless channel, the preselection process includes determining a number of sets based on a first characteristic of the wireless channels, where each set includes at least one user device, and then determining a subset of user devices by selecting at most one user device from each of the sets. The scheduling of the selected subset of users is based on a scheduling algorithm and a second characteristic of the wireless channels.

In accordance with example embodiments of the invention there is at least a method and apparatus to perform determining one duration of scheduled transmissions for at least one of physical uplink control channels or physical uplink shared channels; determining at least one actual duration over which power consistency and phase continuity can be maintained; applying one or more time-domain window duration based at least in part on the determined at least one actual duration to make the one or more time-domain window duration cover the one duration of the scheduled transmissions; and based on the determined more than one time-domain window duration, performing at least one of modulation or demodulation of the scheduled transmissions

Various embodiments disclosed herein provide for an improved system for selecting and conveying modulation scheme information for an uplink transmission. A network device can determine the channel state information for an uplink transmission based on sounding reference signals received from a user equipment device, and then select a modulation scheme for the uplink transmission based on the channel state information and associated signal to noise ratio. The network device can then send an indication of the selection to the user equipment device using an index number comprising six bits that correspond to an index number in a table of modulation schemes. The table of modulation schemes can include modulation schemes that use transform precoding, as well as modulation schemes that do not use transform precoding.

An apparatus is provided in a communications device. The apparatus comprises at least one processor and at least one memory including computer code for one or more programs. The at least one memory and the computer code are configured, with the at least one processor, to cause the apparatus to determine that at least one of a plurality of logical channels configured for packet duplication is to be deactivated; and determine an allocation of one or more cells associated with the at least one deactivated logical channel to one or more active logical channels of said plurality of logical channels configured for packet duplication.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a set of security levels for a set of physical uplink channels, wherein the set of physical uplink channels are overlapping in time. The UE may transmit one or more of the set of physical uplink channels based at least in part on the set of security levels for the set of physical uplink channels. Numerous other aspects are described.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration for a time domain (TD) control channel element (CCE) bundle that includes at least one TD CCE for single carrier waveforms, wherein a phase continuity is assumed for a duration of the TD CCE bundle. The UE may perform a channel estimation using the TD CCE bundle based at least in part on the phase continuity for the duration of the TD CCE bundle. Numerous other aspects are described.

A user equipment (UE) transmits, to a base station, UE capability information that corresponds to a maximum number of configured pathloss reference signals and/or a maximum number of activated pathloss reference signals. Then, the base station configures the UE for a number of configured pathloss reference signals that is less than or equal to the maximum number of configured pathloss references signals and/or activates a number of pathloss reference signals based on the UE capability information that is less than or equal to the maximum number of activated pathloss references signals.

Embodiments of this application provide a method for measuring a positioning reference signal. A terminal device receives first configuration information sent by a network device, where the first configuration information includes positioning reference signal (PRS) resource information configured by the network device for the terminal device. The PRS resource information includes: a plurality of frequency layers, a plurality of transmission reception points TRPs at each frequency layer, a plurality of resource sets of each TRP, and a plurality of resources in each resource set. The terminal device measures, based on the PRS resource information and a predetermined rule, a part or all of PRSs configured by the network device for the terminal device.

Provided are methods and apparatuses for receiving and sending a reference signal. The receiving method includes: receiving first information sent by a second communication node, wherein the first information is used for indicating a signal parameter of a reference signal; and receiving, according to the first information, a reference signal sent by the second communication node.

The present invention has an object to provide a communication system capable of minimizing effects due to a delay among a plurality of base station devices as much as possible in scheduling for communication with a terminal device in cooperation among the plurality of base station devices. Cells1 to 3 can each perform scheduling without using information for scheduling notified from one or a plurality of cells among pieces of information for scheduling notified from other cells. For example, in a case where an interface between the cell1 and cell3 has a large delay amount, the cell1 performs scheduling without using information S13 notified to the cell1 by the cell3, and the cell3 performs scheduling without using information S11 notified to the cell3 by the cell1.
