Embodiment approach 1

[0058] [Outline of communication system]

[0059] A communication system according to an embodiment of the present invention includes a base station 100 and a mobile station 200 . In the following description, as an example, the base station 100 determines resources to be allocated to the mobile station 200, and notifies information indicating the determined resources. Next, the mobile station 200 performs signal transmission processing including mapping processing to resources based on the notification, and transmits a signal to the base station 100 .

[0060] image 3 It is a block diagram showing a partial configuration of base station 100 according to Embodiment 1 of the present invention. exist image 3 In the illustrated base station 100, the receiving unit 106 receives an uplink signal, and the control unit 101 includes, among the prime factors of the first number representing the amount of first resources available for transmitting the uplink signal, a third number ...

Embodiment approach 2

[0155] In Embodiment 1, an example was described in which the number of uplink data signals and allocation resources are determined for allocation resources, and the data signals are mapped one-to-one to the same number of allocation resources as the number of data signals. In Embodiment 2, an example in which a mapping method of uplink data signals is changed with respect to allocated resources will be described.

[0156] The outline of the communication system, the structure of the base station, the structure of the mobile station, and the operation sequence of the second embodiment are the same as those of the first embodiment, and therefore detailed description thereof will be omitted. Hereinafter, Embodiment 2 will be described with reference to the outline of the communication system described in Embodiment 1, the configuration of the base station, and the configuration of the mobile station.

[0157] In the second embodiment, as in the first embodiment, it is assumed th...

Embodiment approach 3

[0182] In Embodiment 1 and Embodiment 2, an example of determining the number indicating the amount of allocated resources has been described. In Embodiment 3, an example of a method different from Embodiments 1 and 2 for determining the amount of data signals (the number of data signals) will be described.

[0183] The outline of the communication system, the structure of the base station, the structure of the mobile station, and the operation sequence of the third embodiment are the same as those of the first embodiment, and therefore detailed description thereof will be omitted. Hereinafter, Embodiment 3 will be described with reference to the outline of the communication system, the configuration of the base station, and the configuration of the mobile station described in Embodiment 1. FIG.

[0184] In the third embodiment, it is assumed that, similarly to the first embodiment, the control unit 201 allocates resources to the mobile station 200 when the number indicating t...

Abstract

In an operation in a license-exempt band (unlicensed band), the present invention contributes to the provision of a mobile station, a base station, a transmission method and a receiving method which suitably transmit and receive a signal. The mobile station 200 includes: a transmission unit 205 which transmits an uplink signal; and a control unit 201 which, when a first number indicating a first resource amount that can be used in the transmission of the uplink signal includes a third number, which is different from a specific second number, as a prime number, controls the transmission of a signal of a fourth number that does not include the third number as the prime number by using a second resource.

Description

technical field [0001] The present invention relates to a mobile station, a base station, a sending method and a receiving method. Background technique [0002] A communication system called "fifth generation mobile communication system (5G)" has been studied. 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project), which is an international standard organization, has advanced from LTE (Long Term Evolution, Long Term Evolution) and LTE-A (LTE-Advansed, Advanced Long Term Evolution) systems, and may not necessarily be related to LTE and LTE-A have a new way of backward compatibility, that is, NR (NEW RAT (New Radio access technology, new radio access technology)) (for example, non-patent literature 1), and the height of the 5G communication system is studied. change. [0003] In NR, in addition to licensed bands that require authorization, the use of unlicensed bands (unlicensed bands) similar to LTE-LAA (License-Assisted Access) has also been studied ...
