Abstract: A method for operating a communications controller adapted for full duplex (FD) operation includes receiving a measurement report from a user equipment served by the communications controller, the measurement report indicating a first power margin between a current transmit power and a transmit power break point and a second power margin between the current transmit power and a maximum transmit power capable of supporting FD operation, performing FD link adaptation (LA) in accordance with the first power margin and the second power margin to adjust one or more FD configuration parameters of a link between the communications controller and the user equipment, wherein the link includes a downlink and an uplink, and instructing the user equipment to communicate over the link in accordance with the one or more FD configuration parameters.

Abstract: A method for operating a user equipment (UE) includes receiving, by the UE from a transmit-receive point (TRP), a sounding reference signal (SRS) configuration for a SRS resource, determining, by the UE, at least one transmit beam for transmitting a SRS, wherein the at least one transmit beam is determined in accordance with TRP receive beam information and the SRS configuration, and transmitting, by the UE, the SRS on the SRS resource using the at least one transmit beam in accordance with the SRS configuration.

Abstract: Embodiments of this disclosure provide techniques for receiving reference signals by a user equipment (UE) from a base station in a downlink channel, as well as transmitting a linear combination index from the UE to the base station. In particular, the linear combination index identifies a combination of beams selected from a set of beams in accordance with the RS.

Abstract: An embodiment method defines a demodulation reference signal (DMRS) pattern for transmitting DMRSs for rank 3 or rank 4 transmissions. The DMRS pattern specifies 12 REs in total per physical resource block (PRB) for carrying DMRSs on three or four antenna ports in antenna ports 7-14 for rank 3 or rank 4 transmissions. DMRS settings for transmitting DMRS according to the DMRS pattern may be specified using a downlink control information table.

Abstract: When spatial quasi co-location is established between component carriers, beam management, e.g., beam configuration or reference signal configuration, of one component carrier may be performed based at least in part on beam management information of the other. Information specifying that component carriers or reference signals cross component carriers are spatially quasi co-located, or information about a SQCL group including spatially quasi co-located carriers, may be transmitted to a UE, e.g., using broadcast signaling, radio resource control (RRC) signaling, a media access control-control element (MAC-CE), downlink control information (DCI) signaling, or a combination thereof.

Abstract: A method for reporting beam information includes setting, by a user equipment (UE), a report type of a beam information report, wherein the beam information report includes beam indices of communications beams being reported, a reference beam quality measurement of one of the communications beams reported, and a report type field conveying the report type, and sending, by the UE to an access node, the beam information report.

Abstract: The disclosure relates to technology for identifying a user equipment beam index in a base station. The base station indicates one or more resources assigned to the user equipment within a beam failure random access channel (BRACH) resource, and transmits one or more synchronization signal block resources and one or more new beam identification reference signal resources to the user equipment. The base station then receives one of the resources from a group of the one or more resources within the BRACH resource assigned to the user equipment corresponding to the BRACH resource, and identifies a preferred beam index of the user equipment based on information in the BRACH resource and the received one of the resources.

Abstract: A method includes inserting a first reference signal and a plurality of bit fields on a first channel, to produce a first signal, where the plurality of bit fields includes a first bit field indicating whether a second reference signal is transmitted on a second channel, a second bit field indicating whether the first reference signal has the same precoding as the second reference signal, a third bit field indicating whether precoding of the first reference signal is similar to precoding of the second reference signal, or a fourth bit field indicating transmission precoding differences between the first reference signal and the second reference signal. The method also includes performing precoding on the first signal, to produce a first transmission signal, performing precoding on the second channel, to produce a second transmission signal, transmitting, to a receiver, the first transmission signal and transmitting, to the receiver, the second transmission signal.
