Two-Timescale Design for Reconfigurable Intelligent Surface-Aided URLLC

no code implementations11 May 2024 Qihao Peng, Hong Ren, Cunhua Pan, Maged Elkashlan, Ana Garcia Armada, Petar Popovski

The transmission power of the base station and the phase shifts of the RIS are jointly devised to maximize the weighted sum rate while considering the spatially correlation and channel estimation errors.

Resource Allocation for Cell-Free Massive MIMO-aided URLLC Systems Relying on Pilot Sharing

no code implementations21 Mar 2023 Qihao Peng, Hong Ren, Mianxiong Dong, Maged Elkashlan, Kai-Kit Wong, Lajos Hanzo

Specifically, to support multiple devices with limited pilot overhead, pilot reuse among the users is considered, where we formulate a joint pilot length and pilot allocation strategy for maximizing the number of devices admitted.
