The present invention provides a method and system for facilitating improved downlink MIMO sector throughput in the presence of UE DC-offset. The system receives BLER from a plurality of UEs and tracks by L1 computing the DL BLER in a UE; checks if the BLER from the UE allocated with an RB containing a DC subcarrier is above a target BLER and if so the L1 increases the power of the RE containing the DC-subcarrier in steps of 3 dB. If the BLER improves in the UE, the L1 stops further increase of power on the DC subcarrier RE. The L1 maintains the improved UE/sector throughput and the subcarrier RE power. The system further supports a plurality of 5G NR UEs with different bandwidth wherein the DC-carrier of each UE can be worked out by the L2 by a set of predefined instructions.

An electronic device may include a communication circuit configured to transmit and receive data to and from a first external electronic device through a first link of short-range wireless communication while the electronic device operates in a soft AP mode and to transmit and receive data to and from a second external electronic device through a second link of the short-range wireless communication while the electronic device operates in an STA mode; and a processor, wherein the processor may be configured to identify a control method of the first link and the second link, and to configure at least one parameter related to a period during which data transmission and/or reception through the second link is possible based on at least one parameter related to a period during which data transmission and/or reception through the first link is possible corresponding to identifying that the control method does not simultaneously perform data transmission and/or reception through the first link and the second link. Further, various other embodiments are possible.

A communication apparatus includes a circuitry and a transmitter. In operation, the circuitry generates a Demodulation Reference Signal (DMRS) and generates downlink control information indicating a mapping pattern of the DMRS from a plurality of mapping patterns, and the transmitter transmits the DMRS and the downlink control information. The plurality of mapping patterns include a first mapping pattern and a second mapping pattern. Resource elements used for the DMRS of the second mapping pattern are same as a part of resource elements used for the DMRS of the first mapping pattern. A number of the resource elements used for the DMRS of the first mapping pattern is larger than a number of the resource elements used for the DMRS of the second mapping pattern.

The present disclosure provides for adaptive resource management in new radio operations that adapts a numerology including a subcarrier spacing and/or cyclic prefix for a user equipment (UE) traveling at a high speed. A base station may transmit via a plurality of remote radio heads (RRH) to a user equipment (UE) is moving along a high speed track. The base station may transmit, in a first time period, using a first numerology including a first subcarrier spacing and a first cyclic prefix ratio, a first transmission for the UE. The base station may transmit, in a subsequent time period, using a second numerology including a second subcarrier spacing and a second cyclic prefix ratio, a second transmission for the UE. At least one of the second subcarrier spacing is different than the first subcarrier spacing or the second cyclic prefix ratio is different than the first cyclic prefix ratio.

This disclosure provides methods, devices and systems related to UE-aided selective single frequency network (SFN). In some implementations, a UE may obtain a first channel measurement of a first communication channel associated with a serving transmission and reception point (TRP), and a second channel measurement of a second communication channel associated with a neighbor TRP. The UE may further select an SFN condition associated with the first channel measurement or the second channel measurement, and transmit an indication including the SFN condition to one or both of the serving TRP or the neighbor TRP. In some other implementations, a network entity may select whether to configure a transmission scheme according to SFN for at least one of a serving TRP and a neighbor TRP associated with the SFN condition, and communicate with the UE associated with the transmission scheme according to SFN.

Systems and methods for managing a network are disclosed. One method can comprise determining a first modulation rate associated with a network device. A beacon can be transmitted at a second modulation rate, wherein the second modulation rate is greater than the first modulation rate. A user device can be associated with the network device based on the beacon if the user device is configured to support the second modulation rate.

A method can include an integrated circuit device, determining if first communication circuits are operating in a first mode that wirelessly receives data at a first rate or a second mode that wirelessly receives data at a second rate that is lower than the first rate. If the first communication circuits are operating in the second mode, transmitting signals with the second communication circuits at a first power level, and if operating in the first mode, transmitting signals with the second communication circuits at a second power level that is lower than the first power level. In the first mode, X symbols per data bit are received and in the second mode, Y symbols per data bit are received, where X<Y. Corresponding devices and methods are also disclosed.
