Problems solved by technology

This method needs to limit resource block type 2, and additional information is required in its control signaling to distinguish resource block types
The second method to solve the problem of effectively supporting relatively small data packets is to configure relatively small resource blocks in the system. The size of this resource block is determined by considering the requirements of relatively small data packets that may be transmitted in the network, for example Each resource block is configured to contain 12 subcarriers, but at this time the number of resource blocks within the same system bandwidth increases, resulting in an increase in the overhead of uplink and downlink control signaling using this method

Embodiment

[0066] This section presents three embodiments of the invention. 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.

[0067] In these embodiments, the system is configured with two resource block sizes as an example. The method described here is also applicable to the system that only defines one resource block size, but when allocating resources, two resource blocks can be cascaded together for allocation. Condition. At this time, the allocation of resource blocks by the network at the allocation granularity of one resource block is equivalent to the allocation of channel resources according to resource block type 2 in the embodiment; the allocation of resource blocks by the network at the allocation granularity of two resource blocks is equivalent to the allocation of resource blocks according to the resource block in the embodiment Typ...

[0069] In this embodiment, it is assumed that the system bandwidth is 10 MHz, and the system defines two types of localized resource units in the uplink direction, wherein type 1 includes 24 subcarriers, and type 2 includes 12 subcarriers. As shown in FIG. 5 , there are two types of division methods of localized resource units. Here, it is assumed that the network does not limit the number and location of type 2 resource blocks. As Table 2 lists the number of two types of resource units, the system bandwidth can be divided into 25 type 1 resource units, or can be divided into 50 type 2 resource units.

[0076] In this embodiment, it is assumed that the system bandwidth is 10 MHz, and the system defines two types of localized resource units in the uplink direction, wherein type 1 includes 24 subcarriers, and type 2 includes 12 subcarriers. It is assumed here that the network restricts the number and location of type 2 resource blocks, so that the remaining codewords of the control bits indicating the channel allocation mode of type 1 resource blocks can be used to indicate the channel allocation mode of type 2 resource blocks.

[0077] Same as in Embodiment 1, the number of channel allocation modes of type 1 resource blocks is (25+1)·25 / 2=325, which requires Bits of control information indication. In addition to the 325 possibilities for resource block type 1, these 9 bits can also have 2 9 -325=187 codewords can be used to identify other resource allocation situations.

[0078] If these remaining codewords are to be used to indicate the channel allocation methods of all ty...

Abstract

This invention relates to a method for instructing resource distribution information in control signaling including: a network distributes resource blocks to user devices and gets a control bit for instructing resource distribution information to use part of code words of the control bit of distribution information of transfer resource block to instruct a mode of distributing channels with a larger grain size and instructs distributing channels in a smaller grain size with the rest code words and sends L1 / L2 control signaling to instruct the resource block to distribute information and other control information, in which, network distributes channel resource according to different grain sizes to meet the needs of network for transmitting small data packets.

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 channel resource allocation information in a wireless communication system. Background technique [0002] Now, the 3GPP standardization organization has begun to carry out the long-term evolution (LTE) of its existing system specifications. Among the many physical layer transmission technologies, the downlink transmission technology based on Orthogonal Frequency Division Multiplexing (OFDM) and the uplink transmission technology based on Single Carrier Frequency Division Multiple Access (SCFDMA) are research hotspots. 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 and transmit them simultaneously on a group of mutually orthogonal sub-carriers. OFDM technology has performance advantages in...
