摘要： A method of a user equipment (UE) for an uplink power control is provided. The method comprises transmitting, to a base station (BS), UE capability information including a full power transmission capability of the UE, receiving, from the BS, downlink control information (DCI) including a transmit precoding matrix indicator (TPMI), determining a power level for each antenna port at the UE based on the full power transmission capability of the UE and the TPMI, and transmitting, to the BS, UL data via physical uplink shared channel (PUSCH) based on the determined power level for each antenna port at the UE and the TPMI wherein the TPMI indicates a precoding matrix and a number of layers used to transmit the UL data via the PUSCH.

摘要： An information handling system includes an antenna controller that may receive, from a platform sensor, platform sensor information as to a physical configuration usage mode, and receive, from a proximity sensor, information as to a part of a body of a user to an antenna. The antenna controller may also obtain a radio transmit power level value corresponding to the platform sensor information and to the proximity sensing information, send the radio transmit power level value to a radio via a serial interface, and reconfigure the antenna in response to the platform sensor information and the proximity sensing information. A radio may adjust a radio transmit power level to an adjusted radio transmit power level based on the radio transmit power level value.

摘要： Aspects of the present disclosure provide techniques for addressing scenarios where the minimum transmit power supported by a wireless node (e.g., an Integrated Access and Backhaul (IAB) node) is above a minimum value specified by a standard. In some cases, the node may signal information regarding its power configuration so a network entity of the may take it into account (e.g., when allocating or scheduling resources). The power configuration may include an indication of the minimum transmit power supported by the node and/or an indication of a guard band that may help the IAB control adjacent channel leakage.

摘要： Techniques are provided for accurately determining actual and prospective location(s) of radio(s) located in a structure and controlled by a shared spectrum system. By more accurately knowing the location(s) of the radios, the shared spectrum system can more efficiently allocate maximum transmission power(s) to the radio(s), enhance corresponding radio coverage area(s), and/or diminish interference to other radio(s) and/or primary user(s).

摘要： The disclosure provides a method and a device in a node for wireless communication. A first node receives a first signal and a second signal, and the first node transmits a first information block and a second information block in a first time window. The first information block and the second information block are used for determining whether the first signal and the second signal are correctly received respectively; transmit power values of physical layer channels carrying the first information block and the second information block are both a first power value. Through the design in the disclosure, a transmit power of a feedback channel on a sidelink is associated with a priority; and when multiple feedback channels are transmitted in one same time window, a proper transmit power can be determined to optimize performances of the feedback channels on the sidelink.

摘要： A method for operating a user equipment (UE) comprises transmitting UE capability information including a full power transmission capability, wherein the full power transmission capability includes information (I) to indicate multiple transmit precoding matrix indicator (TPMI) groups that deliver full power; receiving configuration information for a physical uplink shared channel (PUSCH) transmission; receiving a TPMI indicating a precoding matrix and a number of layers for the PUSCH transmission; determining the PUSCH transmission based on the configuration information; determining a power level for the PUSCH transmission, wherein the power level corresponds to full power if the TPMI is included in one of the multiple TPMI groups that deliver full power; and transmitting the PUSCH transmission with the determined power level.

摘要： Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.

摘要： A first transmission power level based on a radio frequency exposure limit and a second transmission power level based on the first transmission power level and a probability of detection of a body by a body proximity sensor are determined, where it is ensured that an average usage of the first and second transmission power levels over time does not exceed the transmission power limit, determined based on radio frequency exposure limits. A transmission power gain is determined based on a difference between the first and second transmission power level based on the probability of detection, and a false alarm rate of the body by the body proximity sensor. The transmission power gain may be used as a performance indicator to select from multiple first and second transmission power gains. First and second transmission power gains corresponding to the selected transmission power gain may be stored and applied during transmission.

摘要： Disclosed in some examples is a method for providing a HARQ response in an LTE network for a PUCCH format 1b. The method includes receiving one or more downlink assignments of a bundling window over a wireless downlink control channel; setting a reception status for each sub-frame of a downlink data channel in the bundling window based on whether the sub-frame on the downlink data channel was associated with a particular one of the received downlink assignments and based upon whether the sub-frame was successfully received; setting a reception status of sub-frames of the downlink data channel in the bundling window that did not have a corresponding downlink assignment to a predetermined value; and transmitting a response, the response based upon the reception statuses set by the response module.

摘要： Embodiments of the present disclosure provide a resource selection or reselection method by a user equipment (UE) and the UE in Vehicle to vehicle/pedestrian/infrastructure/network (V2X) communication. The method comprises the steps of: detecting physical sidelink control channel (PSCCH) transmitted by other UE(s); selecting (a) single-subframe resource(s) from single-subframe resources which do not overlap with single-subframe resources reserved by the detected PSCCH; and transmitting physical sidelink shared channel (PSSCH) on the selected single-subframe resource(s).
