Abstract: Embodiments compute a target power level referenced at one Access Point (AP) in accordance with path losses between two or more APs and a Station (STA). The calculated target power level is then transmitted to the STA in a downlink message, which may also include resource allocation information that indicates a location of a resource for transmitting an uplink frame. The STA may then use the target power level to calculate an uplink power level for transmitting the uplink frame over the resource location indicated by the downlink frame. In addition to the path loss values, the target power level may also be computed in accordance with measured interference levels at the APs and/or a target receive power level that is associated with, or otherwise required to decode, the uplink frame.

Abstract: A user equipment (UE) may measure reference signals (RSs) that are transmitted on one or more RS resources, whereby generating a RS measurement. The UE may determine, based on the RS measurement and a reporting rule, a RS resource of the one or more RS resources as a first type of resource of a plurality types of resources, and based thereon, generates a channel state information (CSI) report indicating the RS resource determined as the first type of resource, and reports the CSI report.

Abstract: A method for user equipment-anticipated common beam switching includes receiving, by a user equipment (UE), a set of reference signals from a network controller; sending, by the UE, a measurement report to the network controller based on a first reference signal of the received reference signals; determining, by the UE, that a quantity of the first reference signal reported in the measurement report exceeds a threshold; and based thereon monitoring, by the UE, a physical downlink control channel (PDCCH) over a search space on a first control resource set (CORESET),a spatial quasi-colocation (QCL) field in a transmission configuration indication (TCI) state of the first CORESET being set to a resource index of the first reference signal.

Abstract: A user equipment (UE) may receive first configuration information of a carrier of a serving cell, including a first association of a first group of uplink (UL) signals or channels on the carrier in the serving cell with a first UL timing advance group (TAG) of the UE, and second configuration information of the carrier including a second association of a second group of UL signals or channels on the carrier with a second UL TAG of the UE. The UE may transmit a UL signal/channel in the first group of UL signals or channels according to a TA value of the first UL TAG, and transmit a UL signal/channel in the second group of UL signals or channels according to a TA value of the second UL TAG.

Abstract: A method for indicating a frame structure in a wireless local area network (WLAN) is provided. A sending device generates a transmission frame. The transmission frame includes a physical header. The physical header includes a frame structure indication. A subcarrier polarity of the frame structure indication is used to indicate a frame structure of the transmission frame. The sending device sends the transmission frame to a receiving device. In the transmission frame, a first subcarrier polarity indicates the transmission frame has a first frame structure, in which the physical header includes a field and a time domain repetition of the field; and a second subcarrier polarity indicates the transmission frame has a second frame structure, in which the physical header includes the field but does not include the time domain repetition of the field. The frame structure indication is an orthogonal frequency division multiplexing (OFDM) symbol.
