Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system information receiving method, a base station, and a system information transmitting method,

The present invention relates to an apparatus and method for transmitting and receiving information such as a MIB (Master Information Block) and an SIB (System Information Block) based on a De-Modulation Reference Signal (DMRS).

In a wireless communication system, a base station can transmit system information to an initial cell access procedure of a terminal.

For example, in a LTE (Long Term Evolution) system or a LTE Advanced (LTE) system, a base station transmits a Primary Synchronization Signal / Secondary Synchronization Signal (PSS / SSS) A master information block (MIB) through a broadcast CHannel, and a system information block (SIB) through a Physical Downlink Shared CHannel (PDSCH).

In the initial cell access process, the UE can extract the cell ID through the PSS / SSS. The UE can receive a reference signal (e.g., CRS (Cell-Specific Reference Signal) for PBCH demodulation and receive the MIB through the PBCH using the cell ID. Using the information included in the MIB, (E.g., paging, SIB, group TPC, etc.) that can be received by all the UEs in the cell can be determined based on the resource assignment information of the PDCCH (Physical Downlink Control CHannel) (E.g., SIB-1) over a PDSCH indicated by a PDCCH having a CRC scrambled with an SI-RNTI within a common search space.

On the other hand, a carrier type in which only a data channel is set and an existing control channel is not set is considered to improve data transmission. At this time, the control information for the PDSCH may be considered to be transmitted through an Enhanced Physical Downlink Control Channel (EPDCCH), which is a new control channel set in the data area. However, a terminal that has received only the PSS / SSS and the MIB and has not received the SIB may not know the information about the resource setting for the EPDCCH transmission for indicating the common control information.

An object of the present invention is to provide an apparatus and a method for a base station to transmit setting information for transmission of an EPDCCH that can be used for transmitting common control information to a terminal.

Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. It should be noted that, in adding reference numerals to the constituent elements of the drawings, the same constituent elements are denoted by the same reference symbols as possible even if they are shown in different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 is a diagram illustrating an initial cell access procedure of a UE.

1, a wireless communication system includes an uplink (e.g., a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), and a physical uplink control channel) with a user equipment (PDSCH), a Physical Downlink Control Channel (PDCCH), an Enhanced Physical Downlink Control Channel (EPDCCH), a Physical Random Access Channel (PHICH), and the like. ), A Physical Control Format Information CHannel (PCFICH), a Physical Broadcast CHannel (PBCH), and the like).

In this specification, the terminal 10 is a comprehensive concept of a terminal in a wireless communication. The terminal 10 may be a mobile station (MS), a user terminal (UT) in GSM as well as a UE (User Equipment) in WCDMA, LTE, HSPA, , A subscriber station (SS), a wireless device, and the like.

The base station 20 is generally a station that communicates with the terminal 10 and includes a Node-B, an evolved Node-B (eNodeB), a sector, a Site, a BTS A transceiver system, an access point, a relay node, and the like.

The base station 20 includes various coverage areas such as a megacell, a macro cell, a microcell, a picocell, a femtocell, a radio resource head (RRH), and a relay node communication range.

The base station 20 may be referred to as a Transmission Point (TP) in terms of transmitting downlink communication to the terminal 10 and may be referred to as a Reception Point , RP), or may be referred to as a Point or a Transmission and Reception Point.

Referring to FIG. 1, in an initial cell access process of a UE, the UE 10 receives a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS) transmitted by the Node B 20 (S 102). In the LTE Frequency Division Duplex (FDD), the PSS can be transmitted in the last symbol of the first slot of the subframe # 0 and the subframe # 5 in one radio frame (10 ms), and the SSS can be transmitted in the # 0 and the subframe # May be transmitted in the previous symbol (# n-1) of the last symbol (#n) of the first slot. In LTE TDD, the PSS / SSS can be transmitted at a different location than the FDD. When the terminal 10 detects the PSS and the SSS, it can acquire the cell ID and the downlink synchronization information, and can obtain a cell-specific reference signal (CRS) based on the information obtained based on the PSS / ) To perform additional synchronization and conventional control channel decoding.

The terminal 10 receives the signal from the base station 20 through the PBCH based on the CRS (S104), and extracts the MIB (master information block) transmitted through the PBCH (S106).

The MIB may include a dl-Bandwidth field, a phich-Config field, a systemFrameNumber field, and a spare field as shown in Table 1 below.

The dl-Bandwidth field can be used to indicate the bandwidth of a cell in a resource block (RB) unit. In a LTE and LTE-A system, one cell may be composed of 6, 15, 25, 50, 75, or 100 RBs, and a 3-bit dl- Bandwidth field may be used to indicate one of these values .

The phich-Config field may be used to indicate a PHICH resource to which A / N (Acknowledgment, Negative Acknowledgment) to the PUSCH is transmitted. The phich-Config field is composed of 3 bits, and may include one bit for indicating the PHICH duration and two bits for indicating the PHICH resource. The PHICH duration may indicate the number of OFDM symbols to which the PHICH is allocated. If the value of the PHICH duration is 0 (Normal), the PHICH may be located in the first OFDM symbol of the subframe, 1, the PHICH may be located in the first two or three OFDM symbols of the subframe. The PHICH resource can indicate the resource occupancy of the PHICH and can indicate a value of 1/6, 1/2, 1, or 2.

The systemFrameNumber field may be used to indicate a system frame number of 10 bits. Eight bits out of a 10-bit system frame number are indicated through the systemFrameNumber field, and 2 bits can be obtained implicitly in the decoding of a PBCH that is four radio frame (40 ms) periods.

Then, the spare field of 10 bits is reserved.

PDCCH is mapped to a region excluding the PCFICH and the PHICH in the control region, so that the terminal 10 receiving the information of the resource to which the PHICH is allocated through the MIB can know the resource to which the PDCCH is allocated.

Referring again to FIG. 1, the UE 10 receives a signal through the PDCCH based on the CRS from the Node B 20 (S108), and extracts downlink control information (DCI) transmitted through the PDCCH (S110). The DCI may be control information for a PDSCH to which a system information block (SIB) is transmitted, and may be transmitted through a common search space.

Based on the DCI, the UE 10 receives a signal through the PDSCH based on the CRS from the base station (S112), and extracts the SIB transmitted through the PDSCH (S114).

Thereafter, the terminal 10 and the base station 20 perform a random access procedure (S116), and the terminal 10 can enter the RRC connected state from the RRC idle state.

On the other hand, in the LTE and LTE-A systems, radio wave resources can be divided into a control region in which control information is transmitted and a data region in which data is transmitted. A control channel such as a PDCCH, a PHICH, and a PCFICH may be located in a control region, and a data channel such as a PDSCH may be located in a data region. On the other hand, the EPDCCH, which is the channel through which the control information is transmitted, may be located in the data area. PDCCH, PHICH, PCFICH, etc. located in the control region can be modulated / demodulated based on the CRS, and PDSCH, EPDCCH, etc. located in the data region can be modulated / demodulated based on the DMRS.

Unlike the conventional carrier type (LCT) described above, the next generation LTE-A system has a new carrier type (NCT) which is composed of only a data area in which data is transmitted without a control area in which control information is transmitted. ). In this carrier type, the reference signal (CRS) specified in the cell is not transmitted, and the basic demodulation can be performed based on the DMRS. Also, the CRS-based control channels (PDCCH, PHICH, PCFICH) may not be transmitted.

In the NCT, the downlink control information can be transmitted through the EPDCCH based on the DMRS.

In case of the normal CP, the DMRS related to the EPDCCH can use the antenna ports 107, 108, 109, and 110. In the case of the extended CP, the DMRS associated with the EPDCCH can use the antenna ports 107 and 108.

The resources of the EPDCCH can be configured in EPDCCH set units. Each terminal can be composed of K (1? K? 2) EPDCCH sets. Each EPDCCH set may be defined as a pair of N physical resource blocks (PRBs).

The Radio Resource Control (RRC) settings for each EPDCCH set may comprise the following information:

- N = {2, 4, 8}

- K sets need not all have the same value of N

- PRB pairs in other EPDCCH sets may be completely overlapping, partially overlapping, or not overlapping

The type of the EPDCCH set may be localized or localized.

To signal resources for the EPDCCH set, two bits are required to indicate N = {2, 4, 8}.

May have a value of 6 to 100 and N may have a value of 2, 4, or 8, then r may range from 4 to 38 bits.

In the initial cell access procedure of the UE, the UE must receive control information on the PDSCH to which the SIB is transmitted through the EPDCCH in order to receive the SIB. However, since the configuration information (information on the EPDCCH set) for the EPDCCH is transmitted through the RRC, information on the EPDCCH set can not be received through the RRC in the initial cell access procedure, so common control information is transmitted to the UE There is no way to dictate the set of EPDCCHs that can be used. Hereinafter, an embodiment of the present invention provides a method of indicating an EPDCCH set in which common control information can be transmitted to a UE.

2 is a diagram illustrating an initial cell access procedure of a terminal on the NCT.

2, in the initial cell access process of the UE, the UE 10 receives a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS) transmitted by the Node B 20 (S202). In LTE FDD, the PSS can be transmitted in one radio frame (10 ms) in the last symbol of the first slot of subframe # 0 and subframe # 5, and the SSS can be transmitted in the last slot of # 0 and the end of the first slot of subframe # May be transmitted in the second symbol (# n-1) from the symbol (#n). In LTE TDD, the PSS / SSS can be transmitted at a different location than the FDD. Therefore, when the terminal 10 detects the PSS and the SSS, it can acquire the cell ID and the downlink synchronization information.

The terminal 10 receives a signal from the base station 20 through the PBCH based on the DMRS (S204), and extracts a MIB (master information block) transmitted through the PBCH (S206).

The MIB may include EPDDCH setting information for a common EPDCCH to which control information for a PDSCH for transmitting SIB information is transmitted. The common EPDCCH may be located in an EPDCCH common set in which a plurality of terminals search in common, and the MIB may include EPDCCH common set configuration information. A specific embodiment in which the MIB includes EPDCCH common set configuration information will be described later.

Additionally, the MIB may further include configuration information of the DMRS associated with the common EPDCCH used to demodulate the common EPDCCH. The setting information of the DMRS related to the common EPDCCH may be information indicating the antenna port number of the DMRS. A specific embodiment in which the MIB includes DMRS configuration information will be described later.

In addition, when the A / N information for the PUSCH is transmitted through a channel (hereinafter referred to as EPHICH) set in the EPDCCH common set, the MIB may further include setting information of the EPHICH. A specific embodiment in which the MIB includes EPHICH configuration information will be described later.

2, the UE 10 receives a signal through an EPDCCH (common EPDCCH) based on the DMRS from the base station 20 (S208), and transmits downlink control information (DCI (S210). The DCI may be control information for the PDSCH to which the SIB (System Information Block) is transmitted, and may be transmitted through the EPDCCH common set.

Based on the DCI, the terminal 10 receives a signal through the PDSCH based on the DMRS from the base station (S212), and extracts the SIB transmitted through the PDSCH (S214).

Thereafter, the terminal 10 and the base station 20 perform a random access procedure (S216), and the terminal 10 can enter the RRC connected state from the RRC idle state.

Hereinafter, specific examples of information included in the MIB will be described.

In one embodiment, the MIB may include fields as in Table 2 below.

Comparing Table 2 and Table 1, since the CRS and the PHICH are not transmitted in the NCT, the 3-bit PHICH-Config field in Table 1 is omitted. Instead, a 3 bit EPDCCH common set configuration field is added. At this time, the size of the 3-bit spare field for the spare is not changed and the bit length of the entire MIB is not increased.

As described above with reference to Equation 1, the bit length of the index r for signaling the resource for the EPDCCH set may be 4 to 38 bits, and the 3-bit EPDCCH common set configuration field may indicate all cases I can not. Therefore, in this embodiment, the patterns of the PRB set that can be used most frequently are preset to a maximum of 8, and the 3-bit EPDCCH common set configuration field indicates one of preset patterns.

3 shows a case where the system bandwidth is composed of six resource blocks and the EPDCCH common set is composed of two resource blocks.

Which pattern (or what r value) is used can be predetermined.

The criterion for determining the pattern can be selected from eight patterns capable of obtaining the maximum frequency diversity gain in each system bandwidth. Which of the eight preset patterns is used can be indicated by the EPDCCH common set configuration field of the MIB.

In the above example, one of the eight patterns is indicated by 3-bit instruction information. However, one of the 8 patterns or less can be indicated by instruction information of 3 bits or less within the extent that the size of the spare field is not changed can do.

In another embodiment, the MIB may include fields as in Table 3 below.

In this embodiment, the MIB includes a PRBs set configuration field for indicating the number of resource blocks (N) of the EPDCCH common set, and the pattern of the PRB set in the EPDCCH common set for each resource block number (N) Respectively. A pattern of PRB sets that can be used for each resource block number (N) may be selected as a pattern of PRB sets capable of obtaining a maximum frequency diversity gain. PRBs The set configuration field can be 1 bit, 2 bits or 3 bits.

FIG. 4 shows a case where the system bandwidth is composed of 15 resource blocks, the value of N may be 2, 4, or 8, and the pattern of the PRB set is preconfigured for each N value.

Alternatively, a pattern of one or more PRB sets may be preset for each resource block number (N), and the 3-bit indication information may indicate a combination of the number N of resource blocks of the EPDCCH and a pattern.

In another embodiment, the indication information for the EPDCCH common set may be greater than three bits.

In the above-described embodiments, the setting for the common set of the EPDCCH is instructed by using the instruction information of 3 bits or less, and the spare field is maintained at 10 bits. In this embodiment, the field for information indicating the resource of the EPDCCH common set is m (= 3 + k, k is an integer satisfying 0 <k? 10) bits larger than 3 bits and the spare field is 10- ) Bits. That is, in the present embodiment, it is possible to utilize all of the existing spare field 10 bits or add a part thereof. In certain cases, the indication information may indicate all patterns indicated by the r value in the RRC signaling, but in other cases, that is, if the system bandwidth and the N value are large, all patterns are directed to 13 bits or 3 + k bits There is no number. In this case, the instruction information indicates only a predetermined limited pattern. For example, when the instruction information utilizes 13 bits, it is possible to use only a pattern that can be indicated by 13 bits, or to select and instruct as many as 13 bits as a whole.

In this embodiment, the MIB may include fields as shown in Table 4 below.

5 shows an example where the system bandwidth is composed of 15 resource blocks and N = 2. In this case, the EPDCCH common set configuration field of the MIB may indicate 2 ^m (or 2 ^{(3 + k)} ) patterns.

Table 4 and FIG. 5 relate to an example of selecting a pattern when the value of N is determined. The present invention is not limited thereto, and a field of (3 + k) bits may be used to select a combination of the value of N and a pattern.

In yet another embodiment, the MIB may also indicate DMRS antenna port information in addition to the EPDCCH common set configuration information. Table 5 shows an example of a field included in the MIB in this embodiment.

Table 5 above is the same as Table 2 except for the common DMRS port field of EPDCCH. As another example, it is also possible to use a table in which an EPDCCH common DMRS port field is added to Table 3 or Table 4. [ Table 6 below shows an example in which the EPDCCH common DMRS port field is added to Table 4.

The EPDCCH common DMRS port field may be used to indicate the DMRS antenna port associated with the common EPDCCH. In the case of the normal CP, the antenna port 107/108/109/110 may be indicated by using 4 bits in bitmap form, or 8 combinations thereof may be indicated by 3 bits, or 4 combinations may be used by 2 bits Alternatively, two combinations can be indicated by using one bit. In the case of the extended CP, two bits may be used for the antenna port 107/108 in bitmap form, or two combinations of these may be indicated by using one bit.

In the case of the normal CP, the following Table 7 shows an example in which two bits are indicated for one transmission antenna, Table 9 shows an example in which two bits are indicated for two transmission antennas, Table 10 shows an example in which 1 bit is designated for two transmission antennas. Tables 7 to 10 are presented as examples, and the present invention is not limited thereto.

In yet another embodiment, the MIB may also indicate EPHICH configuration information in addition to the EPDCCH common set configuration information.

In the NCT, the PHICH based on CRS may not be set as a channel for transmitting A / N to the PUSCH. In this NCT, a channel based on the DMRS can be set as a channel for transmitting A / N to the PUSCH, and this channel can be called an Enhanced Physical HARQ Indicator CHannel (EPHICH). The EPHICH may be located in the EPDCCH common set. In this case, since the EPDCCH will be allocated to the resources excluding the resources allocated to EPHICH in the EPDCCH common set, the UE must be able to know information about how much resources the EPHICH occupies in the EPDCCH common set.

Table 11 shows an example of fields included in the MIB in this embodiment.

The EPHICH information added in Table 11 can indicate the number and the exact position of the OFDM symbols to which the EPHICH is transmitted within the EPDCCH common set.

The 1-bit EPHICH duration field may indicate whether the EPHICH has normal duration or extended duration. For example, if the value of the EPHICH duration field indicates a normal duration of 0, one OFDM symbol (i.sup.th symbol) in the common control area is used for the EPHICH, and the value of the EPHICH duration field indicates 1 Two OFDM symbols (i, j th symbol) or three OFDM symbols (i, j, k th symbol) in the common control region can be used for EPHICH. More specifically, it can be set as shown in Table 12 below.

The 2-bit EPHICH resource field may be used to adjust the total amount of EPHICH resources within the corresponding common control area. For example, a 2-bit EPHICH resource field may indicate a value of 1/6, 1/2, 1, or 2.

Alternatively, the EPHICH configuration information may be information indicating that a particular Enhanced Resource Element Group (EREG) in the PRB set to which the common EPDCCH is transmitted may be used for EPHICH. Table 13 shows an example of a field included in the MIB in this example.

In Table 13, the EPHICH setting field of y bits can indicate the index of the EREG that can be used for EPHICH.

The above Tables 11 and 13 illustrate that the MIB further includes an EPHICH setting field in addition to the EPDCCH common set field. It is also possible that the MIB further includes a field for indicating the DMRS port and an EPHICH setting field in addition to the EPDCCH common set field. For example, the MIB may include fields as shown in Table 14.
