Abstract: Disclosed is a method comprising receiving a configuration from a base station, wherein the configuration comprises at least a first subset of power control parameters and a second subset of power control parameters. The first subset of power control parameters and the second subset of power control parameters are assigned to a physical uplink control channel resource. Uplink control information is transmitted or repeated at least to a first transmission reception point and to a second transmission reception point using the physical uplink control channel resource, wherein the first subset of power control parameters is used for transmitting or repeating to the first transmission reception point, and the second subset of power control parameters is used for transmitting or repeating to the second transmission reception point.

Abstract: Techniques of generating CSI reports include designating at least one of the reports as a reference and the other reports as dependent on the reference. For example, a dependent CSI report may have a differential value of a CSI quantity rather than a raw value of the CSI quantity. Because generally for parameters in a CSI report, the differential quantity has a smaller range of values than the raw values of the CSI quantity, a quantization of the differential value of the CSI quantity will have fewer bits than the raw value; for example, for Ll-RSRP, the raw value has 7 bits while the differential value has 4 bits. In another example, a dependent value of a CSI quantity is a flag indicating that the CSI quantity value is located in a reference CSI report.

Abstract: The present disclosure relates generally to the field of wireless communications, and particularly to a technique for performing the beam failure recovery (BFR) of transmission reception points (TRPs) in a multiple-TRP (mTRP) scenario. More specifically, the technique involves defining rules according to which a UE may determine that the TRPs have failed concurrently or the TRPs are considered to fail individually in the mTRP scenario. Such rules are defined based on current counter values of beam failure instance (BFI) counters used by the UE for each of the TRPs. In some embodiments, the rules may be additionally defined based on current timer statuses of timers supervising the BFI counters. By using the rules thus defined, it is possible for the UE to clearly determine when it is required to use the BFR mechanism individually for at least one of the TRPs or concurrently for all the TRPs in one or more cells.

Abstract: According to an example implementation, a method for frequency offset reporting includes transmitting, by a first transceiver, a first tracking reference signal to a user device in a wireless communication system, transmitting, by a second transceiver, a second tracking reference signal to the user device, receiving, by the base station, a channel state information (CSI) reporting signal via an uplink channel, where the CSI reporting signal includes power estimation information. The method includes determining whether to pre-compensate a frequency of a downlink signal with frequency offset information based on the power estimation information, and transmitting, by at least one of the first transceiver or the second transceiver, the downlink signal with the pre-compensated frequency in response to the determination to pre-compensate the frequency of the downlink signal.
