Problems solved by technology

However, before decoding the broadcast control channel, the terminal does not obtain the resource mapping information of the broadcast control channel. Moreover, in order to ensure that the synchronization signal can provide assistance for decoding the broadcast control channel, the resource mapping of the broadcast control channel needs to consider the resource mapping information of the synchronization channel. resource structure

Embodiment 1

[0047] In this embodiment, the frequency reuse factor of the SFH is 3, that is, the available subcarriers of the subframe where the SFH is located are divided into 3 subcarrier sets (Subcarrier Set). There are at least the following methods for group division: (1) Equally spaced extraction: Divide the available subcarriers into multiple sub-blocks in units of multiple subcarriers, and extract the subcarriers in each subblock at equal intervals to form 3 subcarrier sets, preferably, when equal interval extraction is performed in a subblock, the offset between the starting subcarrier and the first subcarrier in the subblock is M subcarriers, and the offsets in different subblocks can be the same Or different, wherein, M is a non-negative integer; (2) Divide the available subcarriers into 3 subcarrier sets according to a specific permutation sequence; (3) Divide the available subcarriers into 3 subcarrier sets equally. For the subcarrier set division method mentioned above, it ca...

example 1

[0049] image 3 The subcarrier set division method of the subframe where the SFH is located in the OFDMA / 5MHz system is described. Such as image 3 As shown, the 432 available physical subcarriers are divided into 8 sub-blocks in units of 54 sub-carriers, and the sub-carriers in the 8 sub-blocks are respectively {0, 2, 1, 0, 1, 0, 2, 1} sub-carriers The offset is extracted at equal intervals to form three subcarrier sets.

[0050] Specifically, such as image 3 As shown, the three sets obtained by extracting subcarriers are

example 2

[0097] Such as Figure 4 As shown, in this example, the available subcarriers are equally divided into three sets, namely {40, 41, 42, ... 181, 182, 183}, {184, 185, 186, ..., 255, 257, ..., 327, 328}, {329, 330, 331, ..., 470, 471, 472}. Wherein, the subcarrier whose index is 256 is a DC subcarrier, so it is not included in the above-mentioned set.

[0098] For a 10MHz system, it can also be equally divided into 3 subcarrier sets. For example, the available subcarriers are equally divided into three sets, namely, {80, 81, 82, ..., 365, 366, 367}, {368, 369, ..., 511, 513, 514, .. ., 655, 656}, {657, 658, 659, ..., 942, 943, 944}. Wherein, the subcarrier whose index is 512 is a DC subcarrier, therefore, it is not in the above-mentioned set.

[0099] In addition, as mentioned above, in addition to the method of equal interval extraction and the method of equal division described in the above examples, when forming a subcarrier set, the available subcarriers can also be divi...

Abstract

A method for mapping resources of broadcast control channel is disclosed. A subframe in which the broadcast control channel is located includes N frequency partitions, and resources of each frequency partition are mapped to be logical resource units, wherein N can be 1 or 3. With this method, subcarrier sets of the broadcast control channel are divided, and the resources of the broadcast control channel are mapped.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a resource mapping method of a broadcast control channel. Background technique [0002] In a wireless communication system, base stations and devices communicate through up / down links, where downlink (forward) refers to the direction from the base station to the terminal, and uplink (reverse) refers to the direction from the terminal to the base station. In common applications, multiple terminals can simultaneously send data to the base station through an uplink, and can also simultaneously receive data from the base station through a downlink. [0003] In a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA) technology, the base station completes the mapping of wireless resources and the allocation of wireless resources, and users realize multiple access by occupying different subcarriers. enter. For example, the base stat...
