Problems solved by technology

However, the capital and operating costs required to acquire, install, and maintain a large number of cells are challenging because a 1000-fold increase in capacity would theoretically be accompanied by a 1000-fold increase in the number of cells deployed
Also, as the cell size shrinks, frequent handovers need to be performed, which increases network signaling overhead and latency

Abstract

A base stations (BS) are configured to perform a coordinated transmission to at least one user equipment (UE). The BS includes a plurality of antenna configured to communicate with the UE. The BS also includes processing circuitry coupled to the plurality of antennas and configured to transmit physical downlink control channel (PDCCH) to the at least one user equipment. The UE includes a plurality of antennas configured to communicate with the BS. The UE also includes a processing circuitry coupled to the plurality of antennas and configured to receive PDCCH from the BS. The PDCCH is included in one or more transmit (Tx) beams. A Tx beam is defined by the cell specific reference signal (CRS) transmitted through the Tx beam. A Tx beam is configured to carry a beam identifier, and the PDCCH is configured to include resource allocation information for the user equipment.

Description

technical field [0001] The present application relates generally to wireless communications and, more particularly, to systems and methods for control channel beam management in millimeter wave communications. Background technique [0002] It is expected that the next generation of mobile broadband communication systems (5G) will need to deliver 100-1000 times the capacity of current 4G systems (such as Long Term Evolution (LTE) and Worldwide Interoperability for Microwave Access (WiMAX)) to meet the projected mobile traffic volume. increase. Existing approaches to increase spectral efficiency are unlikely to meet this explosive demand for wireless data. Current 4G systems use various advanced technologies, including Orthogonal Frequency Division Multiplexing (OFDM), Multiple Input Multiple Output (MIMO), Multi-User Diversity, Space Division Multiple Access (SDMA), Higher Order Modulation and Advanced Coding, and Link adaptation, thereby virtually eliminating the differenc...
