Abstract: A wireless device may receive from a base station one or more messages indicating a first downlink transmission power of reference signals. The wireless device may also measure a first reference signal received power value of the received reference signals in a measurement window. The wireless device also receives a command indicating a time period during which transmission of the reference signals are stopped. The wireless device may further transmit to the base station, after the time period during which transmission of the reference signals are stopped, uplink signals. The uplink transmission power of the uplink signals being determined by the wireless device based on received power of the first reference signal, and the first downlink transmission power.

Abstract: Fast calculation of channel state information using demodulation reference signals (DM-RS) is provided herein. Channel state information is traditionally calculated based on the channel state reference signals (CS-RS). Demodulation reference signals, which are used for channel estimation for a data channel, are transmitted at different times than CS-RS however, and so some portions of the channel state information including layer indicator (LI) and channel quality indicator (CQI) can be calculated based on the demodulation reference signals, allowing a network to adapt more quickly to changing channel conditions, without having to transmit a CS-RS. Generally, precoding matrix indicator and rank indicator, which cannot be determined based on the DM-RS, don't change as often and are more stable over time, thus do not need to be calculated as frequently as the LI and CQI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an adaptation indication that includes a spatial adaptation indication that indicates one or more derived resources associated with a first CSI-RS base resource, each derived resource including a subset of channel state information (CSI) reference signal (CSI-RS) ports of a network entity that are derived from the first CSI-RS base resource, and/or a power adaptation indication that indicates power offsets for the first CSI-RS base resource or for the derived resources. The UE may transmit CSI feedback based at least in part on measurement of a CSI-RS from the derived resources, measurement of the CSI-RS in association with the power offsets, and/or measurement of a base CSI-RS transmitted from the first CSI-RS base resource in association with the power offsets. Numerous other aspects are described.

Abstract: A method and a device for transmitting and receiving channel state information in a wireless communication system are disclosed. A method for transmitting channel state information (CSI) according to one embodiment of the present disclosure may comprise the steps of: receiving configuration information related to CSI from a base station; receiving a CSI-reference signal (CSI-RS) on one or more CSI resources from the base station; and transmitting the CSI to the base station on the basis of the configuration information. The CSI may include a precoding matrix indicator (PMI) corresponding to indexes of a codebook for indicating a precoding matrix, and the PMI may include one or more amplitude coefficient indicators for indicating an amplitude coefficient and/or one or more phase coefficient indicators for indicating one or more phase coefficients.

Abstract: A network element in a wireless network sends, to a target UE, configuration of CSI RSs for use in a time-frequency resource space of a PDSCH. The configuration informs the UE to use the CSI RSs for interference parameter detection of co-scheduled UE(s) in the PDSCH. The network element transmits, toward the target UE, the CSI RSs. A target UE in a wireless network receives, from a network element, configuration of CSI RSs for use in a time-frequency resource space of a physical downlink shared channel. The configuration informs the target UE to use the CSI RSs for interference parameter detection of co-scheduled UE(s) in the PDSCH. The target UE receives, from the network element, the CSI RSs. The target UE performs the interference parameter detection using the CSI RSs.
