Description

  The present invention relates to the field of mobile communication technology, and in particular to a control channel resource allocation method and apparatus.

  Time division multiplexing is used for uplink transmission in TDD (Time Division Duplex) mode.

  In LTE (Long Term Evolution, Long Term Evolution) TDD scheme, seven uplink-downlink subframe configurations, which are specifically shown in Table 1, are defined. Different uplink-downlink subframe configurations may be applied to scenarios with different uplink-downlink service requirements.

  The subframes of the TDD scheme may be classified into three types: uplink subframes, downlink subframes, and special subframes. In Table 1, D represents a downlink sub-frame, S represents a special sub-frame, and U represents an uplink sub-frame. It can be understood from Table 1 that in TDD scheme, in one radio frame, some subframes are uplink subframes and some subframes are downlink subframes. In other words, a portion of the duration of one radio frame is used for uplink transmission and a portion of the duration is used for downlink transmission.

  The structure of the special subframe is shown in FIG. The special subframe includes three parts: DwPTS (Downlink Pilot Time Slot, Downlink Pilot Time Slot), guard period (Guard Period, Guard period), and UpPTS (Uplink Pilot Time Slot, Uplink Pilot Time Slot). . Specifically, DwPTS is used for downlink transmission, for example, for transmission of control channel, data channel, synchronization signal, and pilot signal. The GP is used as a guard period and is not used for uplink and downlink transmissions. The UpPTS is used to transmit an uplink SRS (Sounding Reference Signal, sounding reference signal) or a PRACH (Physical Random Access Channel, Physical Random Access Channel).

  In the TDD scheme, a portion of the duration of one radio frame is used for uplink transmission and a portion of the duration is used for downlink transmission. Uplink subframes and downlink subframes function for UE (User Equipment, user equipment) in time division multiplexing, so the number of subframes available for uplink data transmission is limited. In other words, in the time division multiplexing method, the uplink throughput (data transmission amount per unit time) of this method may be small.

  To clarify the object of the present invention, technical solutions, and advantages of the embodiments, the technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention Explain clearly. Apparently, the described embodiments are a part rather than all of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by one skilled in the art without creative efforts shall fall within the protection scope of the present invention.

  In the TDD scheme, uplink and downlink subframes work for the UE in time division multiplexing, which limits the number of subframes that can be used for uplink data transmission. To this problem, the feasible solution is to change the length of the special time slot GP and the length of the UpPTS, provided that the total length 1 ms of the special subframes is not changed. , And additional resources may be obtained from the UpPTS to transmit an uplink PUSCH (Physical Uplink Shared Channel), i.e., transmit uplink data.

  In the method of transmitting uplink PUSCH by using special subframes, HARQ (Hybrid Automatic Repeat Request, HARQ) technology with ACK / HACK also needs to be used to improve decoding accuracy is there. Based on the above case, the method provided in the embodiment of the present invention is a downlink PHICH (Physical Hybrid-ARQ Indicator Channel, physical hybrid-ARQ indicator channel) corresponding to a special subframe for uplink data transmission. Provide a solution for determining location allocation and time-frequency resources.

Embodiment 1
As shown in FIG. 2, for the above problems, this embodiment of the present invention provides a control channel resource allocation method. The method comprises the following steps.

  In step 201, UE (User Equipment, user equipment) transmits PUSCH (Physical Uplink Shared Channel, physical uplink shared channel) in the current special subframe.

  To use a special subframe for transmission means to use UpPTS (Uplink Pilot Time Slot, uplink pilot time slot) in the special subframe as a subframe for uplink data transmission.

  In step 202, the UE determines a PHICH resource corresponding to the PUSCH according to the uplink resource for PUSCH transmission. In this case, uplink resources for PUSCH transmission include current special subframes.

  In this embodiment of the invention, the uplink resources for PUSCH transmission may include UpPTS for PUSCH transmission or may include uplink subframes (also called uplink normal subframes). it can. Specifically, the following cases A, B and C may be present. In A, the uplink resource may be UpPTS in one special subframe. In B, the uplink resources may be UpPTS in multiple special subframes, eg, two UpPTS in one radio frame. In C, uplink resources may also include at least one UpPTS, and at least one uplink subframe. In B and C above, uplink resources are distributed in a plurality of subframes, and the plurality of subframes may be referred to as bundle subframes.

  In step 203, the PHICH is received by the determined PHICH resource.

  Since the existing LTE scheme uses HARQ technology with ACK / NACK, in the specific HARQ process of the uplink path, the transmitting end UE sends the data packet to the receiving end eNB by using the PUSCH channel. Pause and wait for eNB's response message. After a data packet arrives at the receiving end eNB after a specific transmission delay, the eNB examines the data packet. If reception is correct, the receiver feeds back an acknowledgment (ACK) message by using the downlink control channel PHICH, and if reception is improper, the receiver receives the desired information received. Save and feed back a non-acknowledgement (NACK) message. Upon receiving the ACK message, the UE sends new data, otherwise the UE resends the previously sent data packet, and the eNB combines the retransmitted data packet with the previously received data packet , Perform joint decoding, thereby improving decoding accuracy.

  When the UE transmits the uplink PUSCH, and the eNB processes the uplink PUSCH and feeds back the downlink PHICH, when the UE receives and processes PHICH information, retransmits the PUSCH, or transmits a new PUSCH The process up to is called RTT (round trip time) of one HARQ process. Considering the transmission delay and eNB processing time, the time from when the uplink PUSCH is sent to when the downlink PHICH is received should not be less than 4 ms, and similarly, the transmission delay and the UE processing time Considering, the time from when the downlink PHICH is received to when a new uplink PUSCH is transmitted, or when the uplink PUSCH is retransmitted should not be less than 4 ms. RTT values can not be less than 8 ms.

There may be multiple combinations and features of HARQ techniques based on uplink resources for PUSCH transmission, and in this embodiment of the invention, according to the uplink resources for PUSCH transmission, PHICH resources corresponding to PUSCH may be There may be multiple methods used to make the determination. The main rules in concrete implementation are
The time from when the PHICH is received to when the PUSCH is sent and the time from when the PUSCH is sent to when the feedback PHICH is received, the minimum processing time of the base station or UE, For example, to meet the 3ms requirement,
It is avoided as much as possible that the PHICH resources in one subframe correspond to different HARQ processes, and the current RTT value (from when the data packet is first transmitted to when the data packet is retransmitted). Time) is to be reused as much as possible, or to add additional RTT values as small as possible.

  The above rules are merely used as a reference when the UpPTS is used to transmit the PUSCH, and do not necessarily have to be fulfilled. Specifically, when UpPTS is used to transmit PUSCH, only some of the above rules need to be considered, for example, only rules that include RTT, or include RTT and HARQ processes Rules are considered. The specific implementation steps of determining the PHICH resource corresponding to the PUSCH in step 102 according to the uplink resource for PUSCH transmission under the direction of the above rules include the following steps (FIG. 3): Shown).

  In step 301, the UE determines the subframe position of the PHICH resource corresponding to the PUSCH according to the uplink resource for PUSCH transmission.

  In step 302, the PHICH group number of the PHICH resource is determined according to the subframe position, and the PHICH resource corresponding to the PUSCH is determined according to the subframe position and the PHICH group number.

  In accordance with the above method, the method provided in this embodiment of the invention will now be described in detail with respect to the tables and various uplink-downlink subframe configurations.

  I. Determining the subframe position of the PHICH resource corresponding to the PUSCH by the UE according to the uplink resource for PUSCH transmission, when the subframe of the uplink resource for PUSCH transmission is only the current special subframe, Includes the following:

  Specifically, with respect to the seven uplink-downlink subframe configurations as defined in LTE TDD scheme and shown in Table 1, the following will detail possible solutions of PHICH resources in each configuration. Explain to.

1. When the uplink-downlink subframe configuration is 0 and the current special subframe is subframe n, it is determined that the PHICH resource is located in the K th subframe from the current special subframe n, so,
When n = 1 or 6, K = 5, or when n = 1 or 6, K = 10
It is.

  Specifically, when the user equipment UE transmits the PUSCH in special subframe 1 or 6, it is decided accordingly that the PHICH resource is located in the Kth subframe from special subframe 1 or 6, Here, specific optional values of K can be shown in Table 2.

  In the specific subframe configuration, UL / DL configuration 0 (uplink-downlink subframe configuration 0) results in the following A and B.

  A. As shown in Table 2, in case of K1 = 5, for the PUSCH transmitted in the special subframe n = 1, the UE transmits the corresponding HARQ downlink PHICH feedback information in subframes n = 1 to 5 Receive in subframe (value corresponding to the intersection of row 4 and column 3 of Table 2) (ie, receive PHICH by determined PHICH resource), ie, HARQ corresponding to PUSCH in subframe n = 6 Receive downlink PHICH feedback information. For the PUSCH transmitted in subframe n = 6, the UE supports the corresponding HARQ downlink PHICH feedback information from subframe 6 to the fifth subframe (at the intersection of row 4 and column 8 in Table 2) (Ie, the UE receives HARQ downlink PHICH feedback information corresponding to the PUSCH in subframe n = 1).

  B. As shown in Table 2, when K2 = 10, the UE may transmit corresponding HARQ downlink PHICH feedback information for the PUSCH transmitted in the special subframe n = 1, subframes n = 1 to 10 Receive in subframes (ie, receive PHICH according to determined PHICH resources), ie, receive HARQ downlink PHICH feedback information corresponding to PUSCH in subframe n = 1 in the next radio frame. For the PUSCH transmitted in subframe n = 6, the UE receives HARQ downlink PHICH feedback information corresponding to the PUSCH in subframe n = 6 in the next radio frame.

  In the above embodiment, it is determined that the PHICH resource is located in the fifth or tenth subframe from the current special subframe. Thus, the case where more than two PHICHs are received in one subframe is avoided, and the modifications made to the existing protocol are minimized, while the PUSCH is transmitted and the PHICHs are received. The time interval conforms to the minimum processing time of the base station and the transmission delay is relatively small, or the time interval from the reception of the PHICH to the transmission of the PUSCH conforms to the minimum processing time of the UE And the transmission delay is relatively small.

  Transmission delay is relatively small.

2. When the uplink-downlink subframe configuration is 1, and the current special subframe is subframe n, determine that the PHICH resource is located in the Kth subframe from the current special subframe n, so,
When n = 1 or 6, K = 4,
When n = 1 or 6, K = 5, or when n = 1 or 6, K = 8
It is.

  Specifically, when the user equipment UE transmits the PUSCH in special subframe 1 or 6, it is decided accordingly that the PHICH resource is located in the Kth subframe from special subframe 1 or 6, Here, specific optional values of K can be shown in Table 3.

  In the specific subframe configuration, in the UL / DL configuration 1 (uplink-downlink subframe configuration 1), the following A, B, and C are obtained.

  A. As shown in Table 3, in case of K1 = 4, for PUSCH transmitted in special subframe n = 1, UE corresponding HARQ downlink PHICH feedback information, subframe n = 1 to 4 Receive in subframes (ie, receive PHICH according to determined PHICH resources), ie, receive HARQ downlink PHICH feedback information corresponding to PUSCH in subframe m = 5. For the PUSCH transmitted in subframe n = 6, the UE receives HARQ downlink PHICH feedback information corresponding to the PUSCH in subframe m = 0 in the next radio frame.

  In the above embodiment, it is determined that the PHICH resource is located in the fourth subframe from the current special subframe. Thus, the case where multiple PHICHs are received in one subframe is avoided, and the modifications made to the existing protocol are minimized, while the time interval between PUSCH transmission and PHICH reception Is better adapted to the base station's minimum processing time requirements, and the transmission delay is relatively small.

  B. As shown in Table 3, in the case of K2 = 5, for the PUSCH transmitted in the special subframe n = 1, the UE transmits the corresponding HARQ downlink PHICH feedback information in subframes n = 1 to 5 Receive in subframes (ie, receive PHICH according to determined PHICH resources), ie, receive subframes with n = 6, HARQ downlink PHICH feedback information corresponding to PUSCH.

  II. When the subframe of uplink resource for PUSCH transmission includes the current special subframe and another subframe, the subframe position of PHICH resource corresponding to PUSCH is determined by the UE according to the uplink resource for PUSCH transmission To do includes the following.

Furthermore, the existing protocol Rel-11 further specifies that the uplink PUSCH can be transmitted in subframe bundling or TTI bundling manner. A method of bundling UpPTS and other uplink resources is used to transmit PUSCH, which is equivalent to increasing the amount of time to transmit uplink data in unit time, and thereby , Signal to noise ratio of uplink data reception is improved, and uplink coverage is further increased. In this embodiment of the invention, when the subframes of the uplink resource for PUSCH transmission include the current special subframe and the coordinated subframe bundled with the current special subframe, the uplink resource for PUSCH transmission is used. In response to the UE, determining the subframe position of the PHICH resource corresponding to the PUSCH
According to the cooperative subframe, determining the subframe position of the PHICH resource corresponding to PUSCH.

  In this embodiment of the present invention, a coordinated subframe is a special subframe other than a PUSCH transmission special subframe in a bundle subframe when a special subframe for PUSCH transmission is bundled with another subframe. Point to another subframe.

  The coordinated subframes include at least one uplink subframe in the radio frame of the current special subframe and / or other special subframes in the radio frame other than the current special subframe.

Furthermore, considering the transmission delay and eNB processing time comprehensively, and also considering the transmission delay and UE processing time, the current RTT value (that is, the data packet is retransmitted from the time the data packet is first transmitted) Time) is reused as much as possible, or additional RTT values as small as possible are added. Thus, in this embodiment of the invention, determining the subframe position of the PHICH resource corresponding to the PUSCH by the UE according to the uplink resource for PUSCH transmission is:
According to the last sub-frame L in a cooperation sub-frame, determining the sub-frame position of the PHICH resource corresponding to PUSCH is included.

  Specifically, regarding the seven uplink-downlink subframe configurations as defined in LTE TDD scheme and shown in Table 1, in the following, in each configuration according to the last subframe L in the coordinated subframe, PUSCH A possible solution for determining the subframe position of the PHICH resource corresponding to B. will be described in detail.

  For different configurations, there may be multiple cases, as the position and number of uplink subframes in a specific bundling will be different. In the following, various bundling cases will be described.

  In method 1, all uplink subframes and special subframes in one radio frame are bundled to form one bundle subframe, and one bundle subframe corresponds to one HARQ process. The specific realization may be as follows.

  1. If the uplink-downlink subframe configuration is 0, then special subframes 1 and 6 in the radio frame are bundled with subframes 2, 3, 4, 7, 8 and 9 in the radio frame Sometimes, it is determined that the PHICH resource is located in the last subframe L to the K-th subframe, where L = 9 and K = 6.

  Specifically, when the user equipment UE transmits PUSCH in the special subframe 1 or 6, it is determined that the PHICH resource is located in the last subframe L to the Kth subframe of the bundle subframe accordingly Here, specific optional values of K can be shown in Table 10.

  In Table 10, shaded sub-frames 1, 2, 3, 4, 6, 7, 8, and 9 are bundled with transmission data.

  As shown in Table 10, the uplink-downlink subframe configuration is 0, and special subframes 1 and 6 in one radio frame are subframes 2, 3, 4, 7, 8 in the radio frame. , And 9, for the PUSCH sent in special subframe 1, the UE receives the corresponding HARQ downlink PHICH feedback information in subframe 6 from subframe 9 ie, In subframe 5 in the next radio frame, HARQ downlink PHICH feedback information corresponding to that PUSCH is received.

  In this embodiment, when special subframes 1 and 6 are bundled with subframes 2, 3, 4, 7, 8 and 9 in a radio frame, the bundled subframes can be regarded as whole. Therefore, the subframe position in the original subframe 9 for PHICH reception may be reused as a PUSCH sent by using the special subframe. In this case, minimal changes can be made to the protocol. The time interval from when the PUSCH is transmitted to when the PHICH is received becomes the minimum value when the processing time (3 ms) of the base station is the minimum, which effectively reduces the transmission delay. In addition, in the bundling method, PUSCH transmission of 3 HARQ processes and / or RTT of 30 ms can be realized. For delay sensitive services such as Voice over Internet Protocol (VOIP), the transmission delay generally needs to be about 50 ms, and the RTT value of the HARQ process is Set to 30 ms, which can increase time diversity gain for transmission of sensitive services. The quantity of UpPTS included in the HARQ process is the same, which reduces the complexity of the system (UE or base station) coordinating the processing of the HARQ process.

  2. If the uplink-downlink subframe configuration is 1, then PHICH when the special subframes 1 and 6 in the radio frame are bundled with subframes 2, 3, 7 and 8 in the radio frame It is determined that the resource is located in the last subframe L to the Kth subframe, where L = 8 and K = 6.

  In this embodiment, when the special subframes 1 and 6 are bundled with the subframes 2, 3, 7 and 8 in the radio frame, the bundled subframes can be considered as a whole, thus PHICH The subframe position in the original subframe 8 for reception may be reused for PUSCH sent out by using special subframes. The time interval from when the PUSCH is transmitted to when the PHICH is received becomes the minimum value when the processing time (3 ms) of the base station is the minimum, which effectively reduces the transmission delay. In addition, with this bundling method, PUSCH transmission with RTT of 20 ms of two HARQ processes or PUSCH transmission with RTT of 30 ms of three HARQ processes can be realized. For delay sensitive services such as VOIP, the transmission delay should generally be around 50 ms, and the RTT value of the HARQ process is time diversity for transmission of delay sensitive services It is set to 20 ms or 30 ms, which can increase the gain effectively. In addition, the quantity of UpPTS included in the HARQ process is the same, which reduces the complexity of the system (UE or base station) coordinating the processing of the HARQ process.

  3. If the uplink-downlink subframe configuration is 2, when the special subframes 1 and 6 in the radio frame are bundled with the subframes 2 and 7 in the radio frame, the PHICH resource is the last subframe It is determined to be located in the Lth to Kth subframes, where L = 7 and K = 6, 9, or 19.

In this embodiment, it is determined that the PHICH resource is located in the sixth subframe from the current special subframe, and the time interval from when the PUSCH is transmitted to when the PHICH is received is the base station's The minimum value is obtained when the processing time (3 ms) is minimum, which effectively reduces the transmission delay.

  For PUSCH transmission with RTT of 20 ms for K = 6 or 9 or for PUSCH transmission with RTT of 30 ms for K = 19, for delay sensitive services such as VOIP, transmission delay Is generally about 50 ms, and the RTT value of the HARQ process is set to 20 ms or 30 ms which can effectively increase the time diversity gain for transmission of delay sensitive services. In addition, the quantity of UpPTS included in the HARQ process is the same, which reduces the complexity of the system (UE or base station) coordinating the processing of the HARQ process.

  4. If the uplink-downlink subframe configuration is 3, when the special subframe 1 in the radio frame is bundled with the subframes 2, 3 and 4 in the radio frame, the PHICH resource is the last subframe It is determined to be located in the Lth to Kth subframes, where L = 4 and K = 16.

  5. When the uplink-downlink subframe configuration is 4, when the special subframe 1 in the radio frame is bundled with the subframes 2 and 3 in the radio frame, the PHICH resource is transmitted from the last subframe L. It is determined to be located in the Kth subframe, where L = 4 and K = 6.

  6. When the uplink-downlink subframe configuration is 5, when the special subframe 1 in the radio frame is bundled with the subframe 2 in the radio frame, the PHICH resource is K-th from the subframe 2 It is determined to be located in a subframe, where K = 5, 15, or 25.

  7. If the uplink-downlink subframe configuration is 6, then special subframes 1 and 6 in the radio frame are bundled with subframes 2, 3, 4, 7 and 8 in the radio frame , Determine that the PHICH resource is located in the last subframe L to the K-th subframe, where L = 8 and K = 17.

  In method 2, when one radio frame includes two special subframes, each special subframe can form one bundle subframe, and each bundle subframe separately corresponds to a different HARQ process. The specific realization may be as follows.

1. If the uplink-downlink subframe configuration is 2, special subframe 1 in the radio frame and subframe 2 in the radio frame are bundled to form a first bundle frame and also in the radio frame. When special subframe 6 and subframe 7 in the radio frame are bundled to form a second bundle frame, the subframe position of the PHICH resource corresponding to PUSCH according to the last subframe L in the coordinated subframe It is important to decide
Determining that the first PHICH resource corresponding to the first bundle frame is located in the last subframe L to the K1st subframe, where L = 2 and K1 = 4,
The second PHICH resource corresponding to the second bundle frame is located in the last subframe L to the K2-th subframe, where L = 7 and K2 = 4.

  Specifically, when the user equipment UE transmits PUSCH in the special subframe 1 or 6, it is determined that the PHICH resource is located in the last subframe L to the Kth subframe of the bundle subframe accordingly Here, specific optional values of K can be shown in Table 11.

  In Table 11, subframes 1 and 2 marked with a horizontal line are bundled to form a first bundle frame, and subframes 6 and 7 marked with a vertical line are bundled to form a second bundle frame. Form.

As shown in Table 11, the uplink-downlink subframe configuration is 2, and the special subframe 1 in the radio frame and the subframe 2 in the radio frame are bundled to form the first bundle frame. When forming, for the PUSCH sent in special subframe 1, the UE receives the corresponding HARQ downlink PHICH feedback information in subframe 2 to the fourth subframe, ie the subframe in the radio frame 6, receive HARQ downlink PHICH feedback information corresponding to the PUSCH sent in the special subframe 1. Also,
When the special subframe n = 6 in the radio frame and the subframe m = 7 in the radio frame are bundled to form a second bundle frame, the PUSCH transmitted in the special subframe n = 6 is used. In contrast, the UE receives corresponding HARQ downlink PHICH feedback information in subframe 7 to subframe 4 in the fourth subframe, ie, in subframe 1 in the next radio frame, the PUSCH transmitted in special subframe 6 Receive corresponding HARQ downlink PHICH feedback information.

2. If the uplink-downlink subframe configuration is 3, then special subframe 1 in the radio frame and subframes 2 and 3 in the radio frame are bundled to form a first bundle frame, Subframe 4 in the radio frame, special subframe 1 in the next radio frame, and subframe 2 in the next radio frame are bundled to form a second bundle frame, and also in the next radio frame. Determining the subframe position of the PHICH resource corresponding to the PUSCH according to the last subframe L in the coordinated subframe when subframes 3 and 4 of B are bundled to form a third bundle frame,
Determining that the first PHICH resource corresponding to the first bundle frame is located in the last subframe L to the K-th subframe, where L = 3 and K = 6,
Determining that the second PHICH resource corresponding to the second bundle frame is located in the last subframe L to the K-th subframe, where L = 2 and K = 6,
Determining that the third PHICH resource corresponding to the third bundle frame is located in the last subframe L to the K th subframe, where L = 4 and K = 6.

  In this embodiment, when the special subframe is bundled with another subframe in the radio frame, the bundled subframe can be considered as a whole, thus the original subframe 8 for PHICH reception. Sub-frame positions in may be reused for PUSCH sent by using special sub-frames. The time interval from when the PUSCH is transmitted to when the PHICH is received becomes the minimum value when the processing time (3 ms) of the base station is the minimum, which effectively reduces the transmission delay.

A. The determination of the I _PHICH in this embodiment of the invention is described in more detail by using the example shown in Table 12.

  As can be seen from Table 12, in UL / DL configuration 0, a special subframe 1 or 6 is used to transmit a PUSCH, and the PHICH resource corresponding to the PUSCH is located in the fifth subframe from the special subframe. And so, in this case:

  In configuration UL / DL configuration 0, the following is an example of the case where the same subframe corresponds to the PHICH resource of another PUSCH.

  a. For PUSCH transmitted in special subframe 1 and uplink subframe 2, the corresponding PHICH is received in subframe 6.

In order to distinguish each PHICH resource corresponding to different PUSCH in the same subframe, the PHICH group number indication factor of the PHICH resource corresponding to the PUSCH transmitted in subframe 1 or 2 is I _PHICH = 1 Is defined.

  a. For PUSCH transmitted in special subframe 6 and uplink subframe 7, the corresponding PHICH is received in subframe 1.

In order to distinguish each PHICH resource corresponding to different PUSCH in the same subframe, the PHICH group number indication factor of the PHICH resource corresponding to the PUSCH transmitted in subframe 6 or 7 is I _PHICH = 1 Is defined.

Based on the above case, the PHICH group number indication factor of the PHICH resource corresponding to the PUSCH transmitted in subframes 2 and 7 can be defined as I _PHICH = 1 or subframes 1 and 6 The PHICH group number indication factor of the PHICH resource corresponding to the PUSCH transmitted in can be defined as I _PHICH = 1. In addition, in this configuration, each downlink PHICH corresponding to subframes 3 and 4 is transmitted in the same subframe, and each downlink PHICH corresponding to subframes 8 and 9 is transmitted in the same subframe .

In this configuration, the downlink PHICH is received in the same subframe for the four groups of subframes {1, 2}, {3, 4}, {6, 7}, and {8, 9}. In order to distinguish each PHICH resource corresponding to different PUSCH in the same subframe, in the method provided in this embodiment of the present invention, I _PHICH = 1 of PHICH resource corresponding to one subframe is sub There are two alternatives, selected from each group of frames, for each group of subframes. Under the premise that the above case exists in four groups of subframes of this configuration, there are 16 possible ways to form an I _PHICH with this configuration. In addition, the value of I _PHICH corresponding to the original subframe is reused as much as possible, or the change of the value of I _PHICH corresponding to the original subframe is reduced as much as possible. The value of I _PHICH is selected according to the above rules. To simplify the description, two methods of forming the value of I _PHICH are specifically described below.

  In addition, in UL / DL configuration 6, a special subframe 1 or 6 is used to transmit the PUSCH, the PHICH resource corresponding to the PUSCH is located in the fourth subframe from that special subframe, and so on In this case:

  a. For the PUSCH transmitted in special subframe 1 and the PUSCH transmitted in uplink subframe 8 in the previous radio frame, the corresponding downlink PHICH is received in subframe 5.

In this embodiment of the present invention, the timing from the uplink PUSCH to the downlink PHICH is not less than 4 ms in one RTT cycle, and the UE sends the PUSCH from when the UE receives the PHICH at the time of HARQ retransmission. Given that the time to time is not less than 4 ms, the following provides an example where the RTT is 10 ms.

  When the user equipment UE transmits PUSCH in a special subframe, it is decided accordingly that the PHICH resource is located from the special subframe to the Kth subframe, where the specific of K in each configuration Optional values can be shown in Table 13.

For the PUSCH transmitted in special subframe n = 6, the UE receives the corresponding HARQ downlink PHICH feedback information in subframe 6 to the fifth subframe (ie, the UE receives the next radio Receive HARQ downlink PHICH feedback information corresponding to PUSCH in special subframe n = 1 in the frame).

  In <2> DL / UL configuration 1, for the PUSCH transmitted in the special subframe n = 1, the UE receives corresponding HARQ downlink PHICH feedback information in subframes 1 to 4 (subframe 1) PHICH is received according to the determined PHICH resource), ie, HARQ downlink PHICH feedback information corresponding to PUSCH in special subframe m = 5. For the PUSCH transmitted in special subframe n = 6, the UE receives corresponding HARQ downlink PHICH feedback information in subframe 6 to the fourth subframe. That is, the UE receives HARQ downlink PHICH feedback information corresponding to the PUSCH in the special subframe m = 0 in the next radio frame.

  In <1> DL / UL configuration 2, for the PUSCH transmitted in the special subframe n = 1, the UE receives the corresponding HARQ downlink PHICH feedback information in subframe 1 to the fifth subframe ( PHICH is received according to the determined PHICH resource), that is, in special subframe 6, HARQ downlink PHICH feedback information corresponding to PUSCH is received. For the PUSCH transmitted in special subframe n = 6, the UE receives the corresponding HARQ downlink PHICH feedback information in subframe 6 to the fifth subframe.

In this example, the I _PHICH corresponding to subframes m = 2, 4, 7 and 9 is 1 and within the radio frame of the current special subframe other than subframes m = 2, 4, 7 and 9. It can be defined that I _PHICH corresponding to other subframes is 0.

In subframe configuration 6, downlink PHICHs corresponding to two pairs of subframes are transmitted in the same subframe, and these two pairs of subframes are 1 and 8 and 4 and 6, respectively. Therefore, in this embodiment, the PHICH group number indication factor of the PHICH resource corresponding to the PUSCH transmitted in either subframe of each pair of subframes can be I _PHICH = 1. In this example, the PHICH group number indication factor I _PHICH corresponding to subframes 1 and 6 is 1 and corresponds to other subframes within the radio frame of the current special subframe other than subframes 1 and 6 I _PHICH may be defined to be zero.
