Problems solved by technology

[0022] For the method shown in Figure 3, since it maps the user identification index of each resource block to a fixed number When the number of users scheduled in the current subframe is not an integer power of 2, its user identification index must still be used Indicates that there is redundancy in information, and the use of signaling bits is not very effective

Embodiment

[0084] This part gives six embodiments of the invention, and the embodiments focus on how to process and generate bit blocks indicating resource allocation information. In order to avoid making the description of this patent too lengthy, in the following description, detailed descriptions of functions or devices that are well known to the public are omitted.

no. 1 example

[0086] In this embodiment, it is assumed that each element in the resource block allocation information vector generated by the network is a user index corresponding to the resource block. It is assumed here that the network transmits the number of users scheduled in the current subframe through the common control channel, and sends control signaling including user identifiers and resource allocation information on the shared control channel. Assuming that system resources are divided into 12 resource blocks, and assuming that 5 users are scheduled in the current subframe, the total number of control bits for sending resource allocation information is Assuming that the available user identification indexes are 1, 2, 3, 4, 5, the index 0 is used to indicate that a certain subframe is not allocated in the current subframe.

[0092] In this embodiment, it is assumed that each element in the resource block allocation information vector generated by the network is a user index corresponding to the resource block. It is assumed here that the network transmits the number of users scheduled in the current subframe through the common control channel, and sends information including user identification and resource allocation on the shared control channel. Assuming that system resources are divided into 12 resource blocks, and assuming that 5 users are scheduled in the current subframe, the total number of control bits for sending resource allocation information is Assume that the available user identification indexes are 0, 1, 2, 3, 4, and the index 5 is used to identify that a certain subframe is not allocated in the current subframe.

[0093] FIG. 8 is a schematic diagram of generating resource allocation information bits in this embodiment. The network allocates each resource block to the user accor...

Abstract

The related allocation method for channel resource in wireless communication system comprises: network allocates resource block to every UE, and generates the vector including allocation message; then, network converses the vector into a binary number, and generates complete control signaling. This invention reduces bit expending for control signaling.

Description

technical field [0001] The present invention relates to a wireless communication system, and more specifically relates to a device and a method for indicating allocated channel resources in control signaling of the wireless communication system. Background technique [0002] Now, the 3GPP standardization organization has started to carry out long-term evolution (LTE, Long Term Evolution) of its existing system specifications. Among the many physical layer transmission technologies, the downlink transmission technology based on Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) and the uplink transmission technology based on Single Carrier Frequency Division Multiplexing (SCFDMA, Single Carrier Frequency Division Multiple Addressing) are research hotspot. OFDM technology is essentially a multi-carrier modulation communication technology. Its basic principle is to decompose a high-rate data stream into several low-rate data streams a...
