This application is a divisional application. The invention relates to a transmission method and a transmission device of a physical hybrid retransmission indication channel, wherein the original application number is 200910221157.6, and the application date is 2009, 11 and 2 days.
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for transmitting a Physical hybrid arq Indicator Channel (PHICH for short).
Background
The Long Term Evolution (LTE) system is an important project for the third generation partnership. When the LTE system adopts the conventional cyclic prefix, one time slot comprises uplink or downlink symbols with the length of 7, and when the LTE system adopts the extended cyclic prefix, one time slot comprises uplink or downlink symbols with the length of 6. Fig. 1 is a schematic structural diagram of a physical Resource Block when a system bandwidth of an LTE system is 5MHz, and as shown in fig. 1, one Resource Element (RE) is one subcarrier in one OFDM symbol, and one downlink Resource Block (RB) is composed of 12 consecutive subcarriers and 7 consecutive (6 when a cyclic prefix is extended) OFDM symbols. One resource unit is 180kHz in frequency domain and one time length of a common time slot in time domain, and when resource allocation is performed, resource blocks are allocated as basic units. In the Uplink subframe, a Physical Uplink Control Channel (PUCCH) is located on two side bands of the whole frequency band, and the middle of the PUCCH is used for transmitting a Physical Uplink Shared Channel (PUSCH), and the Channel is used for carrying Uplink data, as shown in fig. 2.
The LTE system defines several physical channels as follows:
physical broadcast channel (Physical broadcast channel, brief)Referred to as PBCH): the information carried by the channel includes a frame number of the system, a downlink bandwidth of the system, a period of a Physical hybrid retransmission indicator channel (pdcch), and a parameter N for determining a number of Physical hybrid ARQ indicator channels (PHICH) groupsg∈{1/6,1/2,1,2}。
PDCCH: the method is used for bearing downlink control information, and comprises the following steps: uplink and downlink scheduling information, and uplink power control information.
The formats of Downlink Control Information (DCI) are classified into the following: DCI formats 0, 1A, 1B, 1C, 1D, 2A, 3A, etc.; the format0 is used to indicate scheduling of a Physical Uplink Shared Channel (PUSCH); the DCI format1, 1A, 1B, 1C, 1D is used for different transmission modes of a Physical Downlink Shared Channel (PDSCH) of a single transport block; DCI format2, 2A is used for different transmission modes of spatial division multiplexing; the DCI format3, 3A is used for transmission of a Physical Uplink Control Channel (PUCCH) and a power control command of the PUSCH.
The PDCCH corresponds to 4 levels (levels), also referred to as 4 PDCCH formats, and corresponds to 1 CCE (Control Channel Element), 2 CCEs, 4 CCEs, and 8 CCEs, respectively, where one CCE corresponds to 9 REGs (Resource-Element group) and one REG corresponds to 4 REs (Resource Element).
Physical uplink shared channel: for carrying uplink transmission data. Control information such as resource allocation, modulation and coding scheme, Cyclic shift of Demodulation Reference Signal (DMRS), and the like related to the channel is set in DCI format0 for UL grant.
Physical Hybrid ARQ Indicator Channel (PHICH for short): and the ACK/NACK feedback information is used for carrying uplink transmission data. The number and duration (duration) of the PHICH groups are determined by system messages in the PBCH of the downlink carrier, and the time-frequency position of the PHICH is determined by the number and duration of the PHICH groups, the antenna configuration of the cell PBCH, the cell ID, the group number of the PHICH and the intra-group sequence index.
Number of PHICH groups for Standard defined frame Structure 1Is determined by the following formula:
Ng∈ {1/6,1/2,1,2} is determined by the system message in the PBCH of the DL carrier where it is located,from 0 toNumbering;
is the bandwidth of the downlink carrier where the PHICH is located;
for the standard defined frame structure 2, the number of PHICH groups per subframe isWherein m isiDetermined from table 1.
TABLE 1
PHICH resource combinationDetermining, wherein:is the group number of the PHICH,is an index of the orthogonal sequences in the set, defined by:
nDMRSis a cyclic shift amount of a Demodulation Reference Signal (DMRS) defined in DCI format 0;
is the spreading factor of the PHICH modulation;
the index is the lowest index of a Physical Resource Block (PRB) allocated by uplink resources, that is, the minimum index of a PRB of the PUSCH;
LTE Release-8 defines 6 bandwidths: 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20 MHz.
The Long-Term Evolution Advanced (Long-Term Evolution Advanced, LTE-Advanced for short) system is an evolved version of LTE elease-8. Unless the 3rd Generation partnership project (3 GPP) TR25.913 is met or exceeded: all the Requirements of the Requirements for Evolved UTRA (E-UTRA) and Evolved UTRAN (E-UTRAN) are also met or exceeded by the Requirements of the Advanced International Mobile Telecommunications Advanced (IMT-Advanced) proposed by the International Telecommunication Union-Radio communication sector (ITU-R). Wherein, the requirement of backward compatibility with LTE Release-8 refers to that: the terminal of LTE Release-8 can work in an LTE-Advanced network; the terminal of LTE-Advanced can work in the network of LTE Release-8. In addition, LTE-Advanced should be able to operate with different size spectrum configurations, including wider spectrum configurations (e.g., 100MHz contiguous spectrum resources) than LTE Release-8, to achieve higher performance and target peak rates. In consideration of compatibility with LTE Release-8, for bandwidths larger than 20MHz, a spectrum aggregation (carrieragregation) manner is adopted, that is:
two or more component carriers (component carriers) are aggregated to support a downlink transmission bandwidth greater than 20 MHz.
The terminal can simultaneously receive one or more component carriers according to the capability:
LTE-a terminals with reception capabilities over 20MHz are capable of receiving transmissions on multiple component carriers simultaneously. The lte Rel-8 terminal can only receive transmissions on one component carrier, e.g. the structure of the component carrier follows the Rel-8 specification.
Due to different spectrum application scenarios, a scenario that multiple uplink component carriers correspond to one downlink carrier may occur, that is, ACK/NACK feedback information corresponding to each uplink component carrier on the multiple uplink component carriers is carried in different physical hybrid retransmission indicator channels (PHICHs) of the same downlink carrier and transmitted, so a new transmission method for a physical hybrid retransmission indicator channel needs to be defined to solve the problem of physical hybrid retransmission indicator channel allocation when the multiple uplink component carriers correspond to one downlink carrier.

Detailed Description
The invention uses the structure to rearrange the index of the physical resource block in the uplink component carrier, so that the ACK/NACK feedback information of different uplink carriers corresponds to different physical hybrid retransmission indication channels.
The method for sending the physical hybrid retransmission indication channel comprises the following steps: in a scene that a plurality of uplink component carriers correspond to one downlink component carrier, rearranging indexes of physical resource blocks in the uplink component carrier, and determining resources of a physical hybrid retransmission indicator channel (PHICH) in the downlink component carrier according to the rearranged indexes; and the base station sends the PHICH for bearing the feedback information of the uplink transmission data according to the PHICH resource.
After rearrangement, the intuitive result is that at least one difference exists between the indexes of the physical resource blocks corresponding to the physical uplink control channels in at least two uplink component carriers. Preferably, the physical resource block indexes corresponding to the starting positions of the physical uplink control channels in the at least two uplink component carriers may be different. It is only necessary to ensure that the physical uplink control channels in each uplink component carrier are staggered. When the physical uplink control channels of the two uplink component carriers are staggered, the physical uplink shared channels in the two uplink component carriers can also be staggered, namely, the corresponding relationship between the index of the physical resource block of the main uplink component carrier and the index of the physical resource block corresponding to the PHICH is different, and the corresponding relationship between the index of the physical resource block of at least one slave uplink component carrier and the index of the physical resource block corresponding to the PHICH is different, so that the problem of index collision is avoided. The main uplink component carrier refers to an uplink component carrier corresponding to the LTE R8 terminal; the slave uplink component carrier is an uplink component carrier corresponding to the non-LTE R8 terminal.
Preferably, the index of the physical hybrid retransmission indicator channel in the downlink component carrier may be determined in one of the following manners:
(1) determining according to the index of a physical resource block (PUSCH) allocated by uplink transmission data and the cyclic shift amount of a corresponding demodulation reference signal;
(2) determining according to the index of the uplink component carrier, the index of a physical resource block (PUSCH) allocated by uplink transmission data and the cyclic shift amount of a corresponding demodulation reference signal;
(3) the method comprises the steps of determining the physical resource block (PUSCH) index allocated by uplink component carrier, the offset and the cyclic shift amount of the corresponding demodulation reference signal, wherein the offset can be configured by high-layer signaling.
The index of the physical resource block allocated to the uplink transmission data is the lowest index of the allocated physical resource block, i.e. the PUSCH, or the highest index of the allocated physical resource block, i.e. the PUSCH. The index of the physical resource block allocated by the uplink transmission data refers to the index after renumbering.
Preferably, the method for rearranging the physical resource blocks in the uplink component carrier is to perform overall cyclic shift on consecutive uplink physical resource blocks. Preferably, when the number of the uplink component carriers is n, the maximum or minimum bandwidth of the uplink component carriers is p resource blocks, and the index of the uplink component carrier is i, the amount of cyclic shift of each uplink component carrier is nOrOrOrWherein p isiThe number of physical resource blocks corresponding to the uplink component carrier i; or the cyclic shift amount is configured by higher layer signaling.
The method for rearranging the physical resource blocks in the uplink component carrier can also divide the continuous uplink physical resource blocks into two continuous uplink physical resource block groups and replace the positions of the two groups. The grouping method can be uniform division, and ensure that the indexes of the physical resource blocks in each group are continuous, if the total number of the physical resource blocks is odd, the physical resource blocks which can not be divided evenly are divided into any group.
Preferably, when the indexes of the physical resource blocks in the uplink component carriers are rearranged, the indexes of the physical resource blocks in the uplink component carriers may be firstly rearranged, then the physical resource blocks of all the uplink component carriers are connected in series, and the physical resource blocks are connected in series according to the sequence of the primary uplink component carrier and the secondary uplink component carrier, and the purpose of the series connection is to avoid the coded indexes from colliding.
Preferably, the primary uplink component carrier refers to an uplink component carrier corresponding to an LTE R8 terminal, or the primary uplink component carrier and the secondary uplink component carrier are configured by a base station.
Preferably, for compatibility with the LTE R8 system, the primary uplink component carrier may not be rearranged, that is, only the uplink component carriers corresponding to the non-LTE R8 terminals are rearranged, that is, only the physical resource block indexes of one or more uplink component carriers in the secondary uplink component carriers are rearranged.
Besides the method of rearrangement and renumbering, the index conflict problem can be avoided by increasing PHICH resources, which comprises the following steps:
PHICH resources are added on the basis of LTE R8, the newly added resources are k times of the LTE R8PHICH reserved resources, and k is a positive number. The LTE R8PHICH reserved resource may be a reserved resource currently configured by LTE R8, or may be a maximum reserved resource configurable by LTE R8, or a maximum reserved resource configurable by LTE R8FDD system; the value of k can be a fixed value, and can also be determined by referring to the number of users through signaling configuration.
Preferably, the newly added resource is used for carrying feedback information from the uplink component carrier.
Preferably, the newly added resource is the last m Control Channel Elements (CCEs) in a CCE that transmits all PDCCHs (physical downlink control channels), and a value of m is determined according to the number of the newly added PHICH resource.
Preferably, in the newly added PHICH resources, each PHICH group corresponds to three resource groups (REGs) in one CCE, and may be three consecutive REGs in one CCE or three REGs at equal intervals.
