Title
Coordinated Subarray Based Multi-User Beam Training for Indoor Sub-THz Communications
Abstract
Hierarchical beam training methods are imposed with some limitations on antenna spacing, the number of antennas and/or radio-frequency (RF) chains, which can not be directly extended to general deployments. To address these issues, this paper investigates a coordinated subarray based beam training scheme for indoor sub-Terahertz (sub-THz) multi-user (MU) communications with split hybrid structures. The capability of concurrent beams offered by multiple subarrays in the hybrid structure is exploited to partition the whole angle domain into multiple orthogonal subregions on the basis of subarrays, and each subregion is exclusively covered with a corresponding subarray without explicit interference among them, such that these multiple narrow beams can be simultaneously shaped in their reduced subregions. Consequently, an increased success rate of angle of departure (AoD) estimation can be obtained with affordable overhead in typical deployments, without limitation on the number of antennas in each subarray. Analysis and simulation results verify the feasibility and the superiority of the proposed scheme.
