Problems solved by technology

[0017] First of all, the hopping of frequency hopping users in the frequency domain may collide with the retransmission of non-frequency hopping users, resulting in the data transmission of colliding frequency hopping users and non-frequency hopping users occupying the same frequency domain resources, and the two interfere with each other , can not achieve the serious consequences of normal transmission;
[0018] Secondly, the frequency diversity gain actually obtained by the frequency hopping user is determined by the resource allocation strategy of the frequency hopping user, but the existing resource allocation strategy cannot guarantee the maximization of the resource diversity gain

[0054] The scheme of the first embodiment of the present invention can be summarized as:

[0055] A1. In the bandwidth of the physical uplink shared channel of the LTE system, the frequency domain in the middle part is allocated to frequency selective scheduling users (ie, non-frequency hopping users), and the frequency domains at both ends are allocated to frequency hopping users.

[0056] For ease of distinction, the frequency domain allocated to frequency hopping users is called a frequency hopping area, and the frequency domain allocated to non-frequency hopping users is called a non-frequency hopping area.

[0057] B1. The frequency bands occupied by frequency hopping users are evenly distributed between the frequency hopping areas at both ends, and the frequency hopping interval is set to 1 / 4 of the system frequency bandwidth, which is 1 / 4 of the bandwidth of the physical uplink shared channel; and The number of RBs occupied by frequency users is always constant.

Abstract

The invention discloses a frequency domain multiplexing method for hopping frequency users and non-hopping frequency users, which comprises the following steps of: dividing at least one frequency domain serving as a non-hopping frequency area and at least two frequency domain serving as hopping frequency areas in the bandwidth of a physical uplink shared channel of an LTE system; separating the hopping frequency areas and the non-hopping frequency area on the frequency domains, and separating the different hopping frequency areas or the different non-hopping frequency areas on the frequency domains; and configuring the non-hopping frequency users in the non-hopping frequency area, and configuring the hopping frequency users in the hopping frequency areas, wherein each hopping frequency of the hopping frequency users hops between the different hopping frequency areas. The invention also discloses a frequency domain multiplexing device for the hopping frequency users and the non-hopping frequency users.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a frequency domain multiplexing method and system for frequency hopping users and non-frequency hopping users. Background technique [0002] Frequency Hopping (Frequency-Hopping Spread Spectrum; FHSS) is to transmit signals in a series of discontinuous narrow-band carriers in a specific form under the condition of time synchronization between the sending end and the receiving end. For a non-specific receiver, FHSS The beating signal generated is just impulse noise to it. [0003] In order to solve the problem of deep channel fading and uplink interference in co-frequency networking, the Long Term Evolution (LTE) stipulates frequency hopping rules on the uplink physical uplink shared channel (PUSCH): type 1 (type 1) and Type 2 (type 2). Uplink frequency hopping in the frequency domain is subject to two restrictions: one is to meet the single-carrier characteristics ...
