Description

Information transmission method

Technical Field

The present invention relates to the field of mobile communications, and in particular, to a physical resource representation method.

Background

The LTE (Long Term Evolution) project is an Evolution of 3G (3rd Generation, third Generation mobile communication) technology, which improves and enhances the 3G over-the-air access technology. Among the physical layer transmission technologies, the Orthogonal Frequency Division Multiplexing (OFDM) technology is a promising one of all downlink schemes due to its high spectrum utilization and low processing complexity, wherein a frame structure of an FDD (Frequency division duplex) model of the LTE system is shown in fig. 1, in which a radio frame of 10ms is divided into two half-frames, each half-frame is divided into 10 slots of 0.5ms, the two slots constitute a subframe of 1ms, one radio frame includes 10 subframes (numbered from 0 to 9), and one radio frame includes 20 slots (numbered from 0 to 19). For a conventional Cyclic Prefix (CP) with lengths of 5.21us and 4.69us, one slot includes 7 uplink/downlink symbols with a length of 66.7us, wherein the Cyclic Prefix length of the first symbol is 5.21us, and the Cyclic Prefix lengths of the remaining 6 symbols are 4.69 us; for an extended cyclic prefix length of 16.67us, one slot contains 6 up/down symbols.

In the LTE system, the first n symbols in a subframe are used for transmitting a physical downlink control channel, the value of n is defined by a physical control format indication channel, and the physical control format indication channel is transmitted on the first symbol of the subframe; transmitting a physical downlink shared channel for transmitting downlink data on the remaining m-n symbols of the subframe, wherein m represents the number of symbols contained in one subframe; the time domain position of the physical downlink shared channel can be determined according to the value n transmitted by the physical control format indicator channel, so that when the position of the physical resource mapped by the physical downlink shared channel is represented, only the position of the frequency domain needs to be determined.

One Resource Element (Resource Element) is one subcarrier in one OFDM symbol, and one downlink Resource Block (Resource Block) is composed of 12 consecutive subcarriers and 7 consecutive (6 for long CP) OFDM symbols, and is 180kHz in the frequency domain and the time length of one general slot in the time domain. In resource allocation, allocation is performed by using resource blocks as basic units. Currently, the minimum allocation unit of a Physical frequency domain Resource is defined as a Physical Resource Block (PRB), and meanwhile, a logical Resource Block (Virtual Resource Block) is also defined during Resource allocation, where the PRB and the VRB are equal in size, the total number of the PRB and the VRB is also equal, the PRB and the VRB are numbered respectively, each VRB only corresponds to one PRB, and the PRB number corresponding to each VRB is different.

Let the index of the VRB be #0, # 1., # n-1; the index of PRB is $0, $ 1., $ n-1; where n represents the number of PRBs.

The LTE standard specifies that signaling overhead for indicating the resource location of a physical downlink shared channel for transmitting D-BCH (dynamic broadcast channel) information, RACH (random access channel) feedback information, and Paging information is limited to only 5 bits, and when HARQ (hybrid automatic repeat request) is not used, the signaling overhead may be 7 bits, and the signaling indicating the size of the original information carried by the physical downlink shared channel is only 3 bits. Therefore, it is necessary to design a physical resource representation method, which can flexibly represent the resource positions of the physical downlink shared channel for transmitting the D-BCH information, the RACH feedback information, and the Paging information under various bandwidths, and has a small signaling overhead, and can satisfy the resource representation of the coexistence situation of the three information parts, but there is no method for representing the resource positions of the physical downlink shared channel for the 3 information at present.

Disclosure of Invention

The invention provides a physical resource representation method, which can flexibly represent the resource positions of physical downlink shared channels for transmitting D-BCH information, RACH feedback information and Paging information under various bandwidths, has relatively low corresponding signaling overhead and can meet the resource representation of the coexistence condition of the three information parts.

In order to solve the above technical problem, the present invention provides an information transmission method for one or a combination of three kinds of information, i.e., dynamic broadcast channel, i.e., D-BCH information, random access channel, i.e., RACH feedback information, and Paging channel, i.e., Paging information, the method comprising:

the sending end and the receiving end appoint a section of Virtual Resource Block (VRB) which is used for transmitting the three information and has continuous index numbers and fixed initial index value and/or termination index value, and appoint the position of the VRB used by the sent information under each condition according to the sending condition of the three information in the subframe;

and when the transmitting end transmits one or a combination of the three information in a subframe, distributing corresponding VRB for the transmitted information according to the appointed VRB position, determining the VRB number used by the transmitted information and indicating in a resource indication signaling.

Further, the transmission method may further have the following characteristics:

the first information, the second information and the third information respectively correspond to D-BCH information, RACH feedback information and Paging information, but the corresponding sequence is not limited, and the positions of VRBs used by the three information are appointed as follows:

fixing a first position as the starting position of the VRB used by the first information;

fixing a second location as a VRB termination location for use with a second message

When the third information and the first information are transmitted in the same subframe, the second position is used as a VRB termination position used by the third information; when the third information and the second information are transmitted in the same subframe, the first position is used as the VRB starting position used by the third information; and when the third information is transmitted in the subframe alone, the first position is used as the starting position of the VRB used by the third information or the second position is used as the ending position of the VRB used by the third information.

the three kinds of information can not be transmitted in one subframe at the same time, the D-BCH information is first information or second information, the RACH feedback information and the Paging information respectively correspond to the remaining two pieces of information, and the corresponding relation is not limited;

and, the resource indication signaling only contains the information of the VRB number used by the sent information.

The positions and the number of the VRBs used by the third information are respectively represented by resource allocation signaling, and when the third information is transmitted simultaneously with the first information and/or the third channel, the positions of the VRBs used by the third information do not conflict with the positions of the VRBs used by the first information and/or the third information;

and the D-BCH information is first information or second information, and when the first information and/or the second information are sent, the resource allocation signaling only contains information of the number of VRBs used by the first information and/or the second information.

the resource used by the third information is indicated by two parts, the first r bit represents the starting position or the ending position of the VRB, the last t bit represents the VRB number, and when r is 2, the four kinds of position information represented by the 2bit are as follows:

the initial position is #0

The initial position is

The termination position is # n-1; or

The initial position is #0

The end position is

The termination position is # n-1; or,

the initial position is #0

The end position is

The termination position is # n-1.

Wherein n is the number of VRBs contained in the segment of VRB, #0 is the starting index value of the segment of VRB,indicating a rounding down.

the second information and the third information respectively correspond to RACH feedback information and Paging information, the corresponding relation is not limited, and the resource indication signaling only contains information of the number of VRBs used by the sent information; the position convention of the VRB used for the three information adopts one of the following two ways:

fixing a first position as the starting position of VRB used by D-BCH information; fixing a second position as the end position of the VRB used by the second information;

when the third information and the D-BCH information are sent in the same subframe, the starting position of the used VRB is the next VRB of the last VRB used by the D-BCH information; when the third information and the D-BCH information are not sent in the same subframe, the used VRB initial position is the first position;

or,

concatenating the first information, the second information, and the third information, mapping to a connected segment of VRBs, and determining its location in one of two ways:

when sending, as long as there is first information, determining the VRB starting position used by the first information as a first position, if there is no first information but there is second information, then determining the VRB starting position used by the second information as the first position, if there is only third information, then determining the VRB starting position used by the third information as the first position; or

When sending, as long as there is first information, the end position of VRB used by the first information is determined as a second position, when there is no first information but there is second information, the end position of VRB used by the second information is determined as the second position, if there is only third information, the end position of VRB used by the third information is determined as the second position.

Detailed Description

The present invention is further described below with reference to the accompanying drawings and specific embodiments by taking a 3GPP LTE system as an example:

the 3GPP LTE system bandwidth is 5MHz, and contains 512 subcarriers in total, wherein the number of available subcarriers is 300 in the middle, and since each resource block contains 12 continuous subcarriers, the 5MHz bandwidth contains 25 resource blocks in total, as shown in fig. 2.

A segment of VRB with continuous indexes is selected, the starting index value and/or the ending index value of the segment of VRB are/is fixed, and the indexes of the segment of VRB are assumed to be #0, # 1. Generally, the segment of VRB is a set of VRBs that can be used by one subframe. And transmitting the D-BCH information, RACH feedback information and Paging information of the physical downlink shared channel by using the VRB. For convenience of description, the first information, the second information and the third information are also used hereinafter to correspond to the D-BCH information, the RACH feedback information and the Paging information, respectively, but the order of correspondence is not limited. I.e., the first information may be D-BCH information, RACH feedback information, or Paging information, as well as the second information and the third information.

There are 2 scenarios according to whether these three kinds of information can be transmitted in one sub-frame at the same time.

First embodiment

In this embodiment, the above three kinds of information cannot be transmitted in one subframe at the same time. The location convention for the VRB used for each type of information is as follows:

the starting position of the VRB used by the first information is a fixed position # s, that is, assuming that the number of RBs used for transmitting the first information is k, the frequency domain physical resource position is the frequency domain position where the physical resource block corresponding to VRB # s, # s + 1. Preferably, s is equal to the starting index value of the segment VRB, e.g., # 0.

The VRB termination position used by the second information is # d, that is, assuming that the number of RBs used for transmitting the second information is h, the frequency domain physical resource position is the frequency domain position where the physical resource block corresponding to VRB # d-h +1, # d-h + 2. Preferably, d is equal to the termination index value of the segment VRB, e.g., # n-1.

The position of the third information is related to whether another information is transmitted in the same subframe, and whether the first information or the second information is transmitted, which can be divided into the following three cases:

when only the third information is transmitted in the subframe, the starting position of the VRB used by the third information is # s, that is, assuming that the number of RBs used for transmitting the third information is g, the frequency domain physical resource position of the VRB is the frequency domain position where the physical resource block corresponding to VRB # s, # s + 1., # s + g-1 is located; in this case, if the VRB termination position used by the third information is # d, the frequency domain physical resource position may be the frequency domain position of the physical resource block corresponding to VRB # d-g +1, # d-g + 2.

When only the third information and the first information are transmitted in the subframe, the VRB termination position used by the third information is # d, that is, assuming that the number of RBs used for transmitting the third information is g, the frequency domain physical resource position is the frequency domain position where the physical resource block corresponding to VRB # d-g +1, # d-g + 2.

When only the third information and the second information are transmitted in the subframe, the starting position of the VRB used by the third information is # s, that is, assuming that the number of RBs used for transmitting the third information is g, the frequency domain physical resource position is the frequency domain position where the physical resource block corresponding to VRB # s, # s + 1., # s + g-1 is located.

The location-based engagement method is summarized as using the start index value of the segment of VRB as the VRB start location for the first message, using the end index value of the segment of VRB as the VRB end location for the second message, using the end index value as the VRB end location for the third message when the third message is transmitted in the same subframe as the first message, using the start index value as the VRB start location for the third message when the third message is transmitted in the same subframe as the second message, using the end index value as the VRB end location for the third message or using the start index value as the VRB start location for the third message when the third message is transmitted in a subframe alone, but it is required to be defined first.

In this embodiment, the D-BCH information is used as the first information or the second information, that is, the position thereof is fixed. The RACH feedback information and Paging information correspond to the remaining two pieces of information, respectively, and the correspondence relationship is not limited. If the first information is D-BCH information, the second information is RACH feedback information, and the third information is Paging information. In which case k may be 5. h may be 5. g may be 5 or 7. But the invention is not limited thereto. Other embodiments are also described herein and will not be described in detail.

Furthermore, the k and h values are determined by corresponding resource allocation signaling, the resource allocation signaling can directly represent the k and h values, the code rate of corresponding information can be transmitted, and the number of allocated resource blocks is deduced from the code rate and the number of original information bits. Other embodiments are the same, and are not described again.

In this embodiment, by using the above indication manner and the restriction locations, the corresponding processing flows of the sending end and the receiving end are as follows:

step 110, the sending end and the receiving end appoint a segment of VRB with continuous index numbers for transmitting D-BCH information, RACH feedback information and Paging information of a physical downlink shared channel, fix the starting index value and the ending index value of the segment of VRB, and appoint the starting position or the ending position of the VRB used by the information, which is detailed above;

step 120, the sending end sends one or two of the first information, the second information and the third information on a physical downlink shared channel in a subframe, when sending, the number of VRBs used by the sent information needs to be determined, corresponding VRBs are allocated according to an appointed position, and meanwhile, the number of VRBs used by the sent information is indicated through a resource indication signaling (which can be sent on a physical control format indication channel);

step 130, the receiving end detects the D-BCH channel, RACH information and Paging channel corresponding to the above information, and can determine the VRB location used by the transmitted information according to the detection result and the location convention of each information under the condition, and can correctly receive the transmitted information by combining the number of VRBs used by the information indicated by the resource indication signaling.

Specifically, there are several cases:

if only a D-BCH channel can be detected, the receiving end can determine the starting position or the ending position of the VRB used by the D-BCH information according to the convention, and then the D-BCH information can be correctly received according to the VRB number used by the D-BCH information indicated by the resource indication signaling;

if the D-BCH channel and the RACH feedback channel or the D-BCH channel and the Paging channel can be detected, the D-BCH information can be received according to the same method in the previous paragraph, meanwhile, according to the convention, the starting position or the ending position of the VRB used by the RACH feedback information or the Paging information is determined when the starting position or the ending position of the VRB is simultaneously transmitted with the D-BCH information, and the RACH information or the Paging information can be correctly received by combining the number of VRBs used by the RACH information or the Paging information indicated by the resource indication signaling.

If the RACH feedback channel and/or the Paging channel can be detected, at this time, according to the convention, the starting position or the ending position of the VRB of the RACH feedback channel and/or the Paging channel when no D-BCH information is transmitted at the same time is also determined, and the receiving end can correctly receive the RACH information and/or the Paging information according to the number of VRBs used for indicating the RACH information and/or the Paging information.

No processing is required if the RACH feedback channel and/or Paging channel is not detected.

The D-BCH channel is a broadcast channel that all terminals can detect. Whereas the RACH feedback channel and Paging channel are typically only detectable by some terminals, such as the paged terminal. In the present embodiment, the position of the D-BCH information is fixed, one of the RACH information and Paging information is fixed, and the other one corresponds to a certain position according to the existence of the D-BCH channel, so that the positions can be known.

Second embodiment

In this embodiment, the three kinds of information may be transmitted in one subframe at the same time, and is also suitable for a case where the three kinds of information cannot be transmitted in one subframe at the same time. The location convention for the VRB used for each type of information is as follows:

In this embodiment, the starting position and the number of VRBs of the physical downlink shared channel for transmitting the third information are represented by resource allocation signaling, the resource used by the third information is indicated by two parts, the first r bit represents the starting position or the ending position of the VRBs, and the last t bit represents the number of the VRBs.

When r is 2, the 2bit may represent four kinds of position information, as respectively represented:

the initial position is #0

The initial position is

The termination position is # n-1; or

The initial position is #0

The end position is

The termination position is # n-1; or,

the initial position is #0The end position isThe termination position is # n-1.

Of course, when the transmitting end determines the location of the VRB used by the third information, for example, when the first channel and/or the second information are transmitted simultaneously in the subframe, the location of the VRB used by the third information cannot conflict with the location of the VRB fixedly used by the first information and/or the second information.

The present embodiment takes the D-BCH information as the first information or the second information, i.e., fixes its position. The RACH feedback information and Paging information correspond to the remaining two pieces of information, respectively, and the correspondence relationship is not limited.

In this embodiment, by using the above-mentioned agreed location and indication method, the corresponding processing flow is as follows:

a sending end and a receiving end appoint a segment of VRB with continuous index numbers of D-BCH information, RACH feedback information and Paging information for transmitting a physical downlink shared channel, fix the initial index value and the termination index value of the segment of VRB, and appoint the initial position or the termination position of the VRB used by the information, which is detailed above;

a sending end sends one or any combination of the first information, the second information and the third information on a physical downlink shared channel in a subframe, the number of VRBs used by the sent information is determined and corresponding VRBs are distributed according to an appointed position during sending, the number of the VRBs used by the sent information is indicated through a resource indication signaling, and for the third information, the VRB position used by the information is indicated in the resource indication signaling;

the receiving end detects the D-BCH channel, the RACH information and the Paging channel:

if a D-BCH channel can be detected, a receiving end can determine the starting position or the ending position of a VRB used by the D-BCH information according to convention, and then the D-BCH information can be correctly received according to the VRB number indicated by the resource indication signaling;

if the RACH feedback channel can be detected, the receiving end can determine the starting position or the ending position of the VRB used by the RACH feedback information according to the convention, and then the RACH feedback information can be correctly received according to the VRB number indicated by the resource indication signaling;

if the Paging channel can be detected, the receiving end directly determines the VRB resource used by the Paging information according to the VRB position and the number indicated in the resource allocation signaling, namely, the Paging information can be correctly received.

Third embodiment

The present embodiment can be applied to two scenarios in which D-BCH information, RACH feedback information, and Paging information can be transmitted simultaneously in one subframe, or cannot be transmitted simultaneously in one subframe. The location convention for the VRB used for each type of information is as follows:

the starting position of the VRB used by the D-BCH information is a fixed position # s, that is, assuming that the number of RBs used for transmitting the D-BCH information is k, the frequency domain physical resource position is the frequency domain position where the physical resource block corresponding to VRB # s, # s + 1., # s + k-1 is located. Preferably, s is equal to the starting index value of the segment VRB, e.g., # 0. k may be 5.

The VRB termination position used by the RACH feedback information is # d, that is, assuming that the number of RBs used for transmitting the RACH feedback information is h, the frequency domain physical resource position is the frequency domain position where the physical resource block corresponding to VRB # d-h +1, # d-h + 2. Preferably, d is equal to the termination index value of the segment VRB, e.g., # n-1. h may be 5.

When the Paging information and the D-BCH information are transmitted in the same subframe, the starting position of the used VRB is the next VRB of the last VRB used by the D-BCH information, namely VRB # s + k.

When the Paging information and the D-BCH information are not transmitted in the same subframe, the initial position of the used VRB is a fixed position # s.

The above convention of the VRB location used by the Paging information and the RACH feedback information may also be interchanged.

Another similar approach is:

the VRB termination position used by the D-BCH information is # D, that is, assuming that the number of RBs used for transmitting the D-BCH information is h, the frequency domain physical resource position is the frequency domain position where the physical resource block corresponding to VRB # D-h +1, # D-h + 2. Preferably, d is equal to the termination index value of the segment VRB, e.g., # n-1. h may be 5.

The initial VRB position used by the RACH feedback information is a fixed location # s, that is, assuming that the number of RBs used for transmitting the RACH feedback information is k, the frequency domain physical resource position is the frequency domain position where the physical resource block corresponding to VRB # s, # s + 1. Preferably, s is equal to the starting index value of the segment VRB, e.g., # 0. k may be 5.

When the Paging information and the D-BCH information are transmitted in the same subframe, the used VRB termination position is the previous VRB of the first VRB used by the D-BCH information, namely VRB # D-h.

When the Paging information and the D-BCH information are not transmitted in the same subframe, the used VRB termination position is a fixed position # D.

By adopting the indication method, the corresponding processing flows at the transmitting end and the receiving end are basically the same as those of the first embodiment, and the difference is that:

a sending end sends one or any combination of the first information, the second information and the third information on a physical downlink shared channel in a subframe, the number of VRBs used by the sent information is determined and the corresponding VRBs are distributed according to the appointed position when sending, and meanwhile, the number of the VRBs used by the sent information is indicated through a resource indication signaling;

the receiving end detects the D-BCH channel, RACH information and Paging channel corresponding to the information, the VRB position used by the transmitted information can be determined according to the detection result and the position convention of each information under the condition, and the transmitted information can be correctly received by combining the VRB number used by the information indicated by the resource indication signaling.

Compared with the first embodiment, there is a case that when the receiving end detects the D-BCH channel, the RACH feedback channel and the Paging channel at the same time, the receiving end can also determine the VRB positions used by the D-BCH information, the RACH feedback information and the Paging information according to the convention, and the receiving end can correctly receive the information according to the indicated number of the VRBs used by the information.

Fourth embodiment

The present embodiment can be applied to two scenarios in which D-BCH information, RACH feedback information, and Paging information can be transmitted simultaneously in one subframe, or cannot be transmitted simultaneously in one subframe. The present embodiment assumes that the terminal can detect the D-BCH channel, the RACH feedback channel, and the Paging channel.

The location convention for the VRB used for each type of information is as follows:

when D-BCH information, RACH feedback information and Paging information are sent in a current subframe, the used VRB positions are connected in series according to the sequence of the D-BCH information, the RACH feedback information and the Paging information, and are mapped to continuous VRB index numbers starting from a fixed initial position # s;

specifically, the positions of the VRBs used by the D-BCH information, the RACH feedback information, and the Paging information are allocated from a fixed starting position # s according to consecutive VRB index numbers, that is, assuming that the number of RBs used for transmitting the D-BCH information is k, the number of RBs used for transmitting the RACH feedback information is h, and the number of RBs used for transmitting the Paging information is g, the frequency domain physical resource positions of the D-BCH information are the frequency domain positions where the physical resource blocks corresponding to VRB # s, # s + 1., # s + k-1 are located; the frequency domain physical resource position of the RACH feedback information is the frequency domain position of a physical resource block corresponding to VRB # s + k, # s + k + 1., # s + k + h-1; the frequency domain physical resource position of the Paging information is the frequency domain position of the physical resource block corresponding to VRB # s + k + h, # s + k + h + 1., # s + k + h + g-1; . Preferably, s is equal to the starting index value of the segment VRB, e.g., # 0. k. h and g can be 5.

In the current subframe, there is a case of transmitting only partial information of the D-BCH information, the RACH feedback information, and the Paging information, so the convention is as follows:

and D-BCH information is placed at the top as long as D-BCH information exists, namely the starting position of the VRB used by the D-BCH information is determined as the position of the VRB corresponding to the starting index value of the segment of VRB, when the D-BCH information does not exist but the RACH feedback information exists, the starting position of the VRB used by the RACH feedback information is determined as the position of the VRB corresponding to the starting index value of the segment of VRB, and if only the Paging information exists, the starting position of the VRB used by the Paging information is determined as the position of the VRB corresponding to the starting index value of the segment of VRB.

Alternatively, another similar embodiment is:

and D-BCH information is put at the end as long as D-BCH information exists, the end position of the VRB used by the D-BCH information is determined as the position of the VRB corresponding to the VRB of the segment of VRB end index value, when the D-BCH information does not exist but the RACH feedback information exists, the end position of the VRB used by the RACH feedback information is determined as the position of the VRB corresponding to the segment of VRB end index value, and if only the Paging information exists, the end position of the VRB used by the Paging information is determined as the position of the VRB corresponding to the segment of VRB end index value.

The above D-BCH information, RACH feedback information and Paging information may be interchanged without stipulating who must be placed at the forefront or the rearmost.

The above description is only an example of the present invention, and is not intended to limit the present invention, and it is obvious to those skilled in the art that various modifications and variations can be made in the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
