Abstract

Methods, apparatus and systems for preamble aggregation in random access procedures are described. In one embodiment, a method for preamble aggregation performed by a wireless communication device is disclosed. The method includes transmitting a first message to a wireless communication node, the first message including a plurality of copies of a preamble for access to the wireless communication node, wherein the number is an integer greater than 1, and wherein the preamble Copies of are respectively carried by different uplink random access channel (RACH) opportunities; and monitor the second message within the response time window, the second message includes a response to the first message from the wireless communication node, wherein, at All copies of the preamble are transmitted before the response time window expires.

Description

technical field [0001] The present disclosure relates generally to wireless communications, and more particularly, to methods, apparatuses, and systems for preamble aggregation in random access procedures in wireless communications. Background technique [0002] Fifth-generation (5G) New Radio (NR) mobile communications will be systematically networked on higher carrier frequencies than those used in 2G, 3G, and 4G systems. At present, the industry has widely and internationally recognized frequency bands mainly ranging from 3GHz to 6GHz, and from 6GHz to 100GHz. Compared with the networking frequency of the early communication system, these frequency bands are relatively high, and the loss is large during the propagation process, and the coverage radius is relatively small under the same power. In order to keep similar coverage consistent with legacy systems such as 2G, 3G, and 4G, the coverage of the 5G next-generation mobile communication system should be enhanced, espec...
