This invention discloses a method for controlling uplink power in a single-cell cellular network based on a graph attention-conditional generation and diffusion model. The method optimizes the network energy efficiency of the uplink data transmission model in a single-cell cellular network using the Tinkelbach optimization method. A graph-structured dataset is constructed based on the single-cell cellular network and user equipment (UE). The graph attention-conditional generation and diffusion model is then constructed for uplink power control. This model is trained using the training set and supervised learning target labels from the graph-structured dataset. Based on channel state information and constraint boundaries, the trained graph attention-conditional generation and diffusion model is used to sample the user's uplink transmission power. Based on the sampled user uplink transmission power value, the uplink power of the single-cell cellular network is controlled. The sampled UE transmission power can approximate the upper limit of network energy efficiency to a large extent, thereby ensuring communication quality.

One apparatus may determine a transmit power for transmitting an uplink control channel transmission including first UCI having a first priority and second UCI having a second priority that is lower than the first priority. The apparatus may further transmit, to a network entity using the transmit power, the uplink control channel transmission including the first UCI having the first priority and the second UCI having the second priority. Another apparatus may transmit, to a UE, uplink power control information configuring at least one value for at least one parameter that is associated with transmit power control on an uplink control channel. The other apparatus may further receive, from the UE based on the uplink power control information, an uplink control channel transmission including first UCI having a first priority and second UCI having a second priority that is lower than the first priority.

Embodiments of the present disclosure provide an uplink power control method, a base station, a terminal, a storage medium, and a computer program product. The uplink power control method is applied to a base station and comprises: indicating a first power offset value and / or a first power adjustment value to a terminal, such that the terminal controls an uplink power of a sensing signal on the basis of a sounding reference signal (SRS) uplink power control scheme, the first power offset value, and / or the first power adjustment value. The first power offset value is used to compensate for a path loss difference between sensing and communication, and the first power offset value is a dynamically variable value obtained through algorithmic computation. The first power adjustment value is selected from a power adjustment value candidate set and is used to determine a closed-loop power adjustment value of the sensing signal, and the power adjustment value candidate set is obtained by extending an SRS power adjustment value set.

Various embodiments herein provide techniques for a unified transmission configuration indicator (TCI) framework for multi-transmission-reception point (TRP) operation in a wireless cellular network. For example, embodiments may relate to use of a joint TCI codepoint to indicate one or more TCI states (e.g., a joint uplink (UL) / downlink (DL) TCI state, a UL TCI state, and / or a DL TCI state). The techniques may be used for multi-downlink control information (DCI) multi-TRP operation and / or single-DCI multi-TRP operation. Embodiments further relate to techniques for transmission repetition and uplink power control. Other embodiments may be described and claimed.
