Embodiment Construction

[0095] As mentioned above in the background art, the resource blocks allocated to the UE for centralized transmission are continuous in the frequency domain, and the resource blocks allocated to the UE for distributed transmission are also continuous in a predefined order. In the present invention, the resource allocation unit (resource block) for centralized transmission and the resource allocation unit (time-frequency pattern) for decentralized transmission are collectively referred to as Time-Frequency Unit (Time-Frequency Unit, TFU), then the resource allocation of the entire communication system is equivalent to For the allocation of continuous time-frequency units.

[0096] The core idea of ​​the present invention is that, on the premise that the time-frequency units allocated to each UE are continuous, only the current scheduling UE ID and the start (or end) position of the continuous time-frequency units allocated to each UE need to be notified, and the UE The position...

Abstract

The invention discloses a distributing indication method for communication system source, which is used in the control signaling united code of several attempting user devices, that includes: the base station determines the source distributing indication signaling according to the start / end location or serial of continuous time-frequency units of several attempting user devices; it sends the control signaling with the source distributing indication signaling to the user devices; said attempting user devices determines the time-frequency source according to source distributing indication signaling. The invention also provides the corresponding base station and user device. Adopting the control signaling united code, it can minimize the cost of source distributing indication signaling.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication system resource allocation indication method and corresponding base station and user equipment. Background technique [0002] At present, in the uplink and downlink transmission of the 3GPP Evolved UTRA (E-UTRA) system, single carrier frequency division multiplexing (SC-FDMA) technology and orthogonal frequency division multiplexing (OFDM) technology are respectively used as uplink and downlink multiple access methods. Both SC-FDMA and OFDM are multi-carrier communication technologies. [0003] In a multi-carrier communication system, multi-user multiplexing is achieved by allocating different time-frequency resources to different users. There are two multiplexing modes for uplink and downlink transmission of the E-UTRA system: Localized Transmission and Distributed Transmission. [0004] Centralized transmission allocates time-frequency resources with a resour...
