Problems solved by technology

In addition, since the signals required for these instructions use separate signals regardless of whether they have a common point, there is a problem that the system design is complicated.
[0018] In addition, since separate signals are used for the activation method of periodic channel feedback and aperiodic channel feedback, and the activation method of transmitting only channel feedback and simultaneous transmission of channel feedback and uplink data, there is a problem that efficient switching cannot be performed.
In addition, there is also a problem that unnecessary processing (blind decoding processing) in the mobile station apparatus increases when an uplink transmission permission signal of another format is reintroduced.

no. 1 Embodiment approach

[0135] Next, a first embodiment of the present invention will be described in a communication system using the base station device 100 and the mobile station device 200 . The mobile station apparatus determines whether to use persistently (persistently) allocated uplink resources (Physical Uplink Shared Channel (PUSCH )) to send the channel feedback report CFR, or use the uplink resource (Physical Uplink Shared Channel (PUSCH)) allocated once (single transmission) to send the channel feedback report CFR.

[0136] The mobile station apparatus transmits using the persistently allocated physical uplink shared channel (PUSCH) when the physical downlink control signal (PDCCH) that performs persistent uplink resource allocation includes information requesting channel feedback report CFR When uplink data (uplink shared channel: UL-SCH) and channel feedback report CFR do not contain information requesting channel feedback report CFR in the physical downlink control signal (PDCCH), the...

no. 2 Embodiment approach

[0204] In the first embodiment, for convenience of description, a case where a base station device and a mobile station device are one-to-one was described as an example, but obviously there may be a plurality of base station devices and mobile station devices. In addition, the mobile station device is not limited to a mobile terminal, and the function of the mobile station device may be installed in a base station device or a fixed terminal. In addition, in the embodiments described above, programs for realizing each function in the base station apparatus and each function in the mobile station apparatus are recorded in a computer-readable recording medium, and the computer system reads the programs stored in the recording medium. The recorded program can be executed to control the base station device and the mobile station device. In addition, the "computer system" mentioned here includes hardware such as an OS and peripheral devices.

[0205] In addition, the "computer-rea...

Abstract

In a mobile communication system in which an space of a physical downlink control channel for a mobile station apparatus to search is defined based on a mobile station identity assigned from a base station apparatus, the base station apparatus places a physical downlink control channel including a first mobile station identity or a physical downlink control channel including a second mobile station identity in a search space of a physical downlink control channel corresponding to the first mobile station identity when the base station apparatus assigns a plurality of mobile station identities to the mobile station apparatus, and when a plurality of mobile station identities is assigned from the base station apparatus, the mobile station apparatus performs decoding processing of the physical downlink control channel including the first mobile station identity and the physical downlink control channel including the second mobile station identity in the search space of the physical downlink control channel corresponding to the first mobile station identity.

Description

technical field [0001] The present invention relates to a mobile station device, a mobile communication system, a communication method, and decoding processing of a physical downlink control channel. Background technique [0002] 3GPP (3 rd Generation Partnership Project) is a project to research and create mobile phone system standards based on the development of W-CDMA (Wideband-Code Division Multiple Access) and GSM (Global System for Mobile Communications) networks. In 3GPP, the W-CDMA system is standardized as the third-generation cellular mobile communication system, and services are sequentially started. In addition, HSDPA (High-Speed ​​Downlink Packet Access), which further increases the communication speed, has also been standardized and started to serve. In 3GPP, the evolution of the third-generation radio access technology (Evolved Universal Terrestrial Radio Access: hereinafter referred to as "EUTRA") is studied. [0003] As a downlink communication scheme in...
