Power control in full duplex communication
Methods, systems, and devices for wireless communications that support power control in full duplex communication are described. In some wireless communications systems, a user equipment (UE) may experience antenna isolation for communication of downlink and uplink data traffic. Based on the antenna isolation, the UE may realize an increased channel capacity for full-duplex communication. As part of the full-duplex communication, the UE may identify characteristics of a potential downlink signal on formatted slots of the channel. The UE may determine an uplink transmit power control configured to account for the characteristics. The determination may include a configured transmit power control for beamformed signaling at the UE, and may be based on signal reception quality for potential downlink transmissions. Based on the determination, the UE may either perform uplink transmission on a resource block allocation of the formatted slots or forgo uplink transmission.
Interference control for uplink transmission
Certain aspects of the present disclosure provide techniques for interference control for uplink transmission, for example, using multiple transmission configurations (e.g., antennas, beams, and/or antenna panels). A method that may be performed by a user equipment (UE) includes determining a transmit power for one or more uplink transmissions to a base station (BS) using one or more transmit power parameters. The one or more transmit power parameters are based, at least in part, on a transmission configuration of the one or more uplink transmissions. The method generally includes transmitting the one or more uplink transmissions to the BS using the determined transmit power.
HIGH-PRIORITY DATA TRANSMISSION HANDLING
A user equipment (UE) may obtain high-priority data (e.g., low latency data) to be transmitted to a base station. In some scenarios, the base station may be transmitting downlink transmissions to the UE or to a different UE, or may be receiving uplink transmissions from the UE or from the different UE. The described aspects enable the UE to timely transmit the high-priority data in these scenarios. In one example, the described aspects enable the UE to transmit, to the base station, while the base station performs one or more scheduled downlink transmissions to the UE or to the different UE, at least one of the high-priority data via a first uplink beam from a set of uplink beams for unscheduled uplink transmissions or an unscheduled data indication indicating that the high-priority data is to be transmitted without an uplink grant.
Method and apparatus for ultra reliable and low latency communication
An operation method of a terminal may comprise receiving, from a base station, information of target transmission points targeted for a report of first channel state information (CSI) among the plurality of transmission points; receiving a first CSI-reference signal (CSI-RS) from the target transmission points; transmitting the first CSI determined based on the first CSI-RS to the base station; receiving, from the base station, information on a first transmission point determined based on the first CSI; receiving, from the first transmission point indicated by the information on the first transmission point, a second CSI-RS; receiving, from the base station, information on a requirement; and transmitting, to the base station, a second CSI including a transmission parameter for achieving the requirement.
Methods and apparatus for grant processing
Certain aspects of the present disclosure relate to methods and apparatus for grant processing in uplink centric subframes. An example method generally includes transmitting a first subframe comprising a first grant that includes information for one or more transmissions on that allocated resources in the first subframe to a user equipment (UE) and transmitting the first subframe, with a second grant that allocates resources in at least a second subframe to occur after the first subframe. Other aspects, embodiments, and features are also claimed and described.
PRE-EMPTIVE SUPPRESSION OF INTER-CELL INTERFERENCE IN CELLULAR WIRELESS COMMUNICATION NETWORKS
Embodiments of a method in an access node of a wireless communication network pre-emptively reduces intercell interference, ICI, in neighboring cells. The access node is configured to transmit downlink traffic to a plurality of user equipments, UEs, in a coverage area of the access node. At least one unscheduled physical resource block, PRB, is detected. Downlink traffic across is diluted across the at least one unscheduled PRB. Finally, transmission power of scheduled PRBs is reduced.
TRANSMISSION CONFIGURATION INDICATOR STATE MODE SWITCHING
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a transmission configuration indicator (TCI) state to use for communications with a network entity after switching between TCI modes (e.g., a joint TCI state mode and a separate TCI states mode for uplink transmission and downlink reception). A UE may autonomously switch between the TCI modes based on a trigger event, and may send an indication to a network entity of the trigger event prior to communicating. A UE may identify a TCI configuration with unconfigured power control parameters. The UE may determine a common power control configuration for communicating with a network entity based on applying a rule to the TCI configuration to determine the power control parameters.
Data processing method, node and terminal
Provided are a data processing method, node and terminal. The method includes: before sending data, a first node performing a perception measurement on a first channel of transmission data within a pre-determined time duration; the first node acquiring a first perception measurement result of the perception measurement; and the first node processing data according to the first perception measurement result. By means of the embodiments of the present application, the problems in the relevant art of an interference between uplink and downlink data transmissions of a neighbor cell or a present cell, and a resource collision can be solved.
Transmit power control
This disclosure describes systems, methods, and devices related to transmit power control (TPC). A device may identify a link measurement request frame from a first station device. The device may determine, for each transmit chain of the first station device, a TPC action to be performed by the first device. The device may cause to send a link measurement report frame comprising a value indicative of the TPC action for each transmit chain. The device may identify an acknowledgement from the first station device.
Antenna SPR as a basis to dynamically cap the MCS index on 5G NR
Methods and systems are provided for dynamically capping an MCS index. A determination that one or more user devices are serviced by a sector of a cell site that has a Sector Power Ratio (SPR) above a threshold is made. Based on the SPR being above the threshold, the MCS index of the one or more user devices is capped. In response to the capped MCS index, a first Quadrature Amplitude Modulation (QAM) value is assigned to at least one of the one or more user devices based on a triangulation area corresponding to a location of the at least one of the one or more user devices.
