Description
Technical field
The present invention relates to GSM, relate in particular to a kind of signaling representing method of frequency-hopping resource.
Background technology
In order to satisfy the demand that people are constantly developed mobile communication; Have some basic demands aspect the selection of uplink radio transmission technology: support scalable bandwidth, moderate peak-to-average force ratio (Peak Average Power Ration; Be called for short a position PAPR)/three gradient amounts (cubicmetric is called for short a position CM), guarantee the orthogonality of uplink etc.The multiplexing multiple access of the single carrier frequency division of single carrier transmission scheme (Single Carrier Frequency Division MultipleAddress; Be called for short a position SC-FDMA) owing to have lower PAPR/CM and can improve the validity of power and expand the coverage area, thus become the basic candidate scheme of present LTE uplink.
The single carrier transmission scheme that most of companies are recommended is at LFDMA (LocalisedFrequency Division Multiple Address; Centralized frequency division multiple access)-FH (Frequency Hopping; Frequency hopping) used frequency hopping in; Both can guarantee good channel estimating performance, can also obtain frequency diversity gain, and can obtain cell interference diversity gain.
General hopping scheme all carries out under single user or multi-user's transmission environment.Under the random frequency hopping situation, if reasonably do not design the frequency hopping pattern, then can not guarantee mutually orthogonal between the user and possibly bump, thereby this can cause serious distortion to cause taking defeat.
The demand of launching shared bandwidth as the up user of LTE not simultaneously, the frequency hopping of mode can cause the discontinuous subcarrier of CU usually, this can make the PAPR/CM of system increase, thereby has violated the design original intention of single-carrier system.At present; Main hopping scheme is divided into subband or subclass with system bandwidth exactly, then, carries out frequency hopping according to the size of subband or subclass; Wherein, Subband or subclass are represented one section continuous resource, and be not overlapping between subband (subclass), and each frequency hopping user's resource only can be distributed in a subband or subclass.
For this reason; Frequency hopping user's resource representation just can be represented according to the mode of subband or subclass; Thereby reduced frequency hopping user's resource signaling signaling consumption, made the bit that saves can be used to transmit frequency-hopping mode, and no longer need transmit frequency-hopping mode through broadcast channel.This frequency hopping also can be called the segmentation frequency hopping, and each section is exactly a subband or subclass.
Summary of the invention
The present invention is directed to third generation partner program Long Term Evolution plan (long termevolution, be called for short position a LTE) ul transmissions scheme, on basis, proposed a kind of signaling representing method of frequency-hopping resource based on the LFDMA transmission plan of segmentation frequency hopping.
In the method; Represent the signaling of frequency-hopping resource wherein, to obtain frequency-hopping resource assignment information: step S102 according to the frequency-hopping resource assignment information according to following steps; With system can with a plurality of subcarriers be that unit is divided into the n section according to Resource Block, and to each the section number; Step S104 sets up the corresponding relation between section and the section; And step S106, obtain the frequency-hopping resource assignment information according to the condition of previous setting.
Wherein, the frequency-hopping resource assignment information is made up of information header, section indicating bit and information bit.
Information header is represented frequency-hopping mode, through the said frequency-hopping mode of binary number representation.
The section indicating bit is represented the numbering of frequency hopping user resources place section, through the numbering of binary number representation section.
Information bit is represented the position of frequency hopping user resources in institute's dispensing section, can be through the method representation information bit of tree-like node.
Can with system can with a plurality of subcarriers be divided into 2 sections, that is, n is 2, makes first section of the time slot of winning with second time slot second section corresponding, second section of first time slot with second time slot first section is corresponding; Or first section of first time slot with second time slot first section is corresponding, and second section of first time slot with second time slot second section is corresponding.
Represent through the information header of 1 bit whether the frequency hopping user resources change the position, and 0 expression does not change, and 1 expression changes in the section of said first time slot and said second time slot.
If said frequency hopping user resources change the position in the section of said first time slot and said second time slot, the Resource Block of then getting in first time slot takes a turn for the worse with respect to the original position of the Resource Block of getting in the original position that belongs to section and the second time slot section with respect to the place section.
Can with system can with a plurality of subcarriers be divided into 3 sections, that is, n is 3; In this case; First section of first time slot with second time slot second section is corresponding, and second section of first time slot with second time slot the 3rd section is corresponding, and the 3rd section of first time slot with second time slot first section is corresponding; Also can be that first section of first time slot with second time slot the 3rd section is corresponding, second section of first time slot with second time slot first section be corresponding, and the 3rd section of first time slot with second time slot second section is corresponding.
If the frequency hopping user resources change the position in the section of said first time slot and said second time slot, the Resource Block of getting in then said first time slot takes a turn for the worse with respect to the original position of the Resource Block of getting in original position that belongs to section and the said second time slot section with respect to the place section.
In addition, confirm the frequency hopping pattern kind through information header, wherein, the frequency hopping pattern kind comprises two sections frequency hoppings and three sections frequency hoppings, and every kind of frequency hopping pattern all comprises the frequency hopping pattern of fixed qty and content, confirms frequency hopping pattern concrete in every kind of frequency hopping pattern according to sub-district ID.
Through top signaling notification target user is frequency hopping user or dispatched users.
This method has reduced the expense of ascending frequency-hopping resource representation signaling, does not need to transmit frequency-hopping mode through broadcast channel again and selects signaling, simultaneously, has also increased the flexibility of ascending frequency-hopping.
