Description

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

Time division multiplexing is used for TDD (Time Division Duplex, time division multiplexing) uplink transmission.

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

TDD scheme subframes can be classified into three types: uplink subframes, downlink subframes, and special subframes. In Table 1, D represents a downlink subframe, S represents a special subframe, and U represents an uplink subframe. It can be seen from Table 1 that some subframes are uplink subframes and some subframes are downlink subframes in one radio frame in the TDD scheme. 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, namely, 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, control channel, data channel, synchronization signal, and pilot signal transmission. GP is used as a guard period and is not used for uplink and downlink transmission. UpPTS is used to transmit an uplink SRS (Sounding Reference Signal, Sounding Reference Signal) or 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. Since the uplink subframe and the downlink subframe function for the UE (User Equipment, user equipment) in the time division multiplexing method, the number of subframes that can be used 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 objects, technical solutions and advantages of the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings related to 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. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

In the TDD scheme, the uplink and downlink subframes function for the UE in time division multiplexing, thus limiting the number of subframes that can be used for uplink data transmission. A feasible solution to this problem is that the number of UpPTS symbols changes the length of the special time slot GP and the length of the UpPTS, provided that the total length of the special subframes is not changed by 1 ms. And additional resources are obtained from the UpPTS to send an uplink PUSCH (Physical Uplink Shared Channel), ie to send uplink data.

In the method of transmitting the uplink PUSCH by using a special subframe, HARQ (Hybrid Automatic Repeat Request) technology by 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 provides a downlink PHICH (Physical Hybrid-ARQ Indicator Channel, Physical Hybrid-ARQ Indicator Channel) corresponding to a special subframe for uplink data transmission. Provides a solution for determining the location allocation and time frequency resources of the.

Embodiment 1
As shown in FIG. 2, with respect to the above problem, this embodiment of the present invention provides a control channel resource allocation method. The method includes the following steps.

In step 201, a UE (User Equipment, User Equipment) sends out a PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) in the current special subframe.

Using a special subframe for transmission means using UpPTS (Uplink Pilot Time Slot, uplink pilot time slot) in the special subframe as a subframe for transmitting uplink data.

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

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

In step 203, 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, after the transmitting end UE sends a data packet to the receiving end eNB by using the PUSCH channel. Pause and wait for eNB's response message. After the data packet reaches the receiving end eNB after a certain transmission delay, the eNB inspects the data packet. If the reception is correct, the receiving end feeds back an acknowledgment (ACK) message by using the downlink control channel PHICH, and if the reception is incorrect, the receiving end receives the desired information received. Save and feed back a non-acknowledgement (NACK) message. Upon receiving the ACK message, the UE sends out new data, otherwise the UE retransmits the previously transmitted data packet and the eNB combines the retransmitted data packet with the previously received data packet. , Perform integrated decoding, thereby improving decoding accuracy.

From when the UE sends the uplink PUSCH and the eNB processes the uplink PUSCH and feeds back the downlink PHICH, and when the UE receives and processes the PHICH information and retransmits the PUSCH or sends a new PUSCH. The processes up to are called RTT (round trip time, round trip time) of one HARQ process. Considering the transmission delay and the 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. Similarly, the transmission delay and the UE processing time are Considering that, the time from when the downlink PHICH is received to when the new uplink PUSCH is transmitted or the uplink PUSCH is retransmitted should not be less than 4 ms. The RTT value does not fall below 8 ms.

There may be multiple combinations and features of HARQ techniques based on the uplink resources for PUSCH transmission, and in this embodiment of the present invention, the uplink resources for PUSCH transmission provide the PHICH resources corresponding to the PUSCH. There can be multiple methods used to determine. The main rules in concrete implementation are:
The time from when the PHICH is received to when the PUSCH is transmitted, and the time from when the PUSCH is transmitted to when the feedback PHICH is received are minimized, the minimum processing time of the base station or UE, 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 the time the data packet is first transmitted to the time the data packet is retransmitted). Time) is reused as much as possible or added with the smallest possible additional RTT value.

The above rules are merely used as a reference when UpPTS is used to transmit PUSCH and do not necessarily have to be met. Specifically, when UpPTS is used to transmit PUSCH, only some of the above rules need to be considered, eg only rules containing RTT, or RTT and HARQ processes. Rules are considered. Under the order of the above rules, the specific implementation step of determining the PHICH resource corresponding to the PUSCH in step 102 by the UE according to the uplink resource for PUSCH transmission includes the following steps (see FIG. 3). Shown in).

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.

According to the above method, the method provided in this embodiment of the present invention will be described in detail below with respect to a table 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, Including:

Specifically, regarding the seven uplink-downlink subframe configurations defined in the LTE TDD scheme and shown in Table 1, the possible solutions of PHICH resources in each configuration are detailed below. Explained.

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

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

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

A. As shown in Table 2, when K1=5, for the PUSCH transmitted in the special subframe n=1, the UE outputs the corresponding HARQ downlink PHICH feedback information from the subframe n=1 to the fifth. Received in a subframe (value corresponding to the intersection of row 4 and column 3 in Table 2) (ie, PHICH is received by the determined PHICH resource), that is, in subframe n=6, HARQ corresponding to PUSCH Receive downlink PHICH feedback information. For the PUSCH transmitted in subframe n=6, the UE sends the corresponding HARQ downlink PHICH feedback information to the fifth subframe from subframe 6 (corresponding to the intersection of row 4 and column 8 of Table 2). Value) (that is, the UE receives HARQ downlink PHICH feedback information corresponding to PUSCH in subframe n=1).

B. As shown in Table 2, for K2=10, for the PUSCH transmitted in the special subframe n=1, the UE sends the corresponding HARQ downlink PHICH feedback information from the subframe n=1 to the 10th subframe. The HARQ downlink PHICH feedback information corresponding to the PUSCH is received in the subframe (that is, the PHICH is received by the determined PHICH resource), that is, in the subframe n=1 in the next radio frame. For PUSCH transmitted in subframe n=6, the UE receives HARQ downlink PHICH feedback information corresponding to 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 5th or 10th subframe from the current special subframe. Therefore, the case where more than two PHICHs are received in one subframe is avoided, and the changes to the existing protocol are minimized, while the PUSCH is transmitted and the PHICH is received. The time interval matches the minimum processing time of the base station and the transmission delay becomes relatively small, or the time interval from the reception of the PHICH to the transmission of the PUSCH matches the minimum processing time of the UE. And, the transmission delay becomes relatively small.

The transmission delay is relatively small.

2. When the uplink-downlink subframe configuration is 1 and the current special subframe is subframe n, it is determined that PHICH resources are located in the Kth subframe from the current special subframe n, and so,
When n=1 or 6, K=4,
When n=1 or 6, K=5, or when n=1 or 6, K=8
Is.

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

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

A. As shown in Table 3, when K1=4, for the PUSCH transmitted in the special subframe n=1, the UE sends the corresponding HARQ downlink PHICH feedback information from the subframe n=1 to the fourth. Receive in a subframe (ie, receive PHICH with determined PHICH resources), ie, in subframe m=5, receive HARQ downlink PHICH feedback information corresponding to PUSCH. For PUSCH transmitted in subframe n=6, the UE receives HARQ downlink PHICH feedback information corresponding to 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. Therefore, the case where multiple PHICHs are received in one subframe is avoided, and the changes made to the existing protocol are minimized, while the time interval between the PUSCH transmission and the PHICH reception. However, it fits better with the minimum processing time requirements of the base station and the transmission delay is relatively small.

B. As shown in Table 3, when K2=5, for the PUSCH transmitted in the special subframe n=1, the UE sends the corresponding HARQ downlink PHICH feedback information from the subframe n=1 to the fifth subframe. Receive in subframe (ie, receive PHICH with determined PHICH resource), ie, in subframe n=6, receive HARQ downlink PHICH feedback information corresponding to PUSCH. For PUSCH transmitted in subframe n=6, the UE receives HARQ downlink PHICH feedback information corresponding to PUSCH in subframe n=1 in the next radio frame.

C. As shown in Table 3, when K3=8, for the PUSCH transmitted in the special subframe n=1, the UE outputs the corresponding HARQ downlink PHICH feedback information from the subframe n=1 to the 8th subframe. Receive in subframe (ie, receive PHICH with determined PHICH resources), ie, in subframe m=9, receive HARQ downlink PHICH feedback information corresponding to PUSCH. For PUSCH transmitted in subframe n=6, the UE receives HARQ downlink PHICH feedback information corresponding to PUSCH in subframe m=4 in the next radio frame.

In the above embodiment, it is determined that the PHICH resource is located in the eighth subframe from the current special subframe. Therefore, the case where more than two PHICHs are received in one subframe is avoided, and the changes to the existing protocol are minimized, while the PUSCH is transmitted and the PHICH is received. The time interval meets the minimum processing time requirement of the base station and the transmission delay is relatively small.

3. When the uplink-downlink subframe structure is 2 and the current special subframe is subframe n, it is determined that the PHICH resource is located in the Kth subframe from the current special subframe n, and so,

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

Furthermore, the existing protocol Rel-11 further defines that the uplink PUSCH can be transmitted in a subframe bundling or TTI bundling method. A method of bundling UpPTS and other uplink resources is used to transmit the PUSCH, which is equivalent to increasing the amount of time to transmit uplink data in a unit of time, thereby , The signal-to-noise ratio of the uplink data reception is improved, and the uplink coverage is further increased. In this embodiment of the present invention, when the subframe of the uplink resource for PUSCH transmission includes the current special subframe and the cooperative subframe bundled with the current special subframe, the uplink resource for PUSCH transmission is Accordingly, determining the subframe position of the PHICH resource corresponding to the PUSCH by the UE is as follows.
It includes determining the subframe position of the PHICH resource corresponding to the PUSCH according to the cooperative subframe.

In this embodiment of the present invention, a cooperative subframe means a special subframe for PUSCH transmission other than a special subframe for PUSCH transmission when the special subframe for PUSCH transmission is bundled with another subframe. Refers to another subframe.

Cooperative 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 the eNB processing time comprehensively, and also considering the transmission delay and the UE processing time, the current RTT value (that is, the data packet is retransmitted from the time when the data packet is first transmitted). Time) is reused as much as possible or an additional RTT value that is as small as possible is added. Therefore, in this embodiment of the present 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
It includes determining the subframe position of the PHICH resource corresponding to PUSCH according to the last subframe L in the cooperative subframe.

Specifically, regarding the seven uplink-downlink subframe configurations defined in the LTE TDD scheme and shown in Table 1, in the following, in each configuration, depending on the final subframe L in the cooperative subframe, the PUSCH A possible solution for determining the subframe position of the PHICH resource corresponding to is described in detail.

There may be multiple cases for different configurations due to different positions and numbers of uplink subframes during specific bundling. 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 implementation may be:

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

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

In Table 10, hatched subframes 1, 2, 3, 4, 6, 7, 8 and 9 are bundled with the transmitted data.

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

In this embodiment, when the special subframes 1 and 6 are bundled with the subframes 2, 3, 4, 7, 8, and 9 in the radio frame, the bundled subframes can be considered as a whole. , Therefore, the subframe position in the original subframe 9 for PHICH reception can be reused as the 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, the bundling method can realize PUSCH transmission of 3 HARQ processes and/or RTS of 30 ms. For delay sensitive services, such as VOIP (Voice over Internet Protocol), the transmission delay should generally be around 50 ms, and the RTT value of the HARQ process should be It is set to 30 ms, which can increase the time diversity gain for the transmission of sensitive services. The number 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 when the special subframes 1 and 6 in a radio frame are bundled with the subframes 2, 3, 7, and 8 in that radio frame, the PHICH It is determined that the resource is located in the Kth subframe from the last subframe L, 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, and thus PHICH The subframe position in the original subframe 8 for reception can be reused for the PUSCH sent by using the special subframe. 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, this bundling method can realize PUSCH transmission with an RTT of 20 ms for two HARQ processes or PUSCH transmission with an RTT of 30 ms for three HARQ processes. For delay-sensitive services such as VOIP, the transmission delay should generally be around 50 ms, and the RTT value of the HARQ process may be time-diversity due to the transmission of delay-sensitive services. It is set to 20 ms or 30 ms, which can effectively increase the gain. In addition, the number 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, the PHICH resource is the last subframe when the special subframes 1 and 6 in the radio frame are bundled with the subframes 2 and 7 in the radio frame. It is determined to be located in the Kth subframe from L, 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 It has a minimum value when the processing time (3 ms) is minimum, which effectively reduces the transmission delay.

For PUSCH transmission with an RTT of 20 ms when K=6 or 9 or PUSCH transmission with an RTT of 30 ms when K=19, a transmission delay for delay sensitive services such as VOIP. Should generally be 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 number 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. When the uplink-downlink subframe configuration is 3, when the special subframe 1 in a radio frame is bundled with the subframes 2, 3 and 4 in the radio frame, the PHICH resource becomes the last subframe. It is determined to be located in the Kth subframe from L, 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, PHICH resources are 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 allocated to the Kth subframe from the subframe 2. It is determined to be located in a subframe, where K=5, 15, or 25.

7. When the uplink-downlink subframe configuration is 6, when special subframes 1 and 6 in a radio frame are bundled with subframes 2, 3, 4, 7, and 8 in the radio frame. , PHICH resources are located in the Kth subframe from the last subframe L, 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 implementation can be:

1. When the uplink-downlink subframe configuration is 2, the special subframe 1 in the radio frame and the subframe 2 in the radio frame are bundled to form a first bundled frame, and also in the radio frame. When the special subframe 6 and the subframe 7 in the radio frame are bundled to form the second bundled frame, the subframe position of the PHICH resource corresponding to the PUSCH according to the final subframe L in the cooperative subframe. To determine
Determining that the first PHICH resource corresponding to the first bundle frame is located in the K1 th subframe from the last subframe L, where L=2, and K1=4,
A second PHICH resource corresponding to the second bundle frame is located in the K2th subframe from the last subframe L, where L=7 and K2=4.

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

In Table 11, subframes 1 and 2 marked with horizontal lines are bundled to form a first bundle frame, and subframes 6 and 7 marked with vertical lines 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 transmitted in special subframe 1, the UE receives the corresponding HARQ downlink PHICH feedback information in the 4th subframe from subframe 2, ie, the subframe in the radio frame. At 6, the HARQ downlink PHICH feedback information corresponding to the PUSCH transmitted in special subframe 1 is received. Also,
When the special subframe n=6 in the radio frame and the subframe m=7 in the radio frame are bundled to form the second bundled frame, the PUSCH transmitted in the special subframe n=6 On the other hand, the UE receives the corresponding HARQ downlink PHICH feedback information in the fourth subframe from the subframe 7, that is, in the subframe 1 in the next radio frame, in the PUSCH transmitted in the special subframe 6. Receive corresponding HARQ downlink PHICH feedback information.

2. When the uplink-downlink subframe configuration is 3, the special subframe 1 in the radio frame and the subframes 2 and 3 in the radio frame are bundled to form a first bundle frame, and The subframe 4 in the radio frame, the special subframe 1 in the next radio frame, and the 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 PUSCH according to the last subframe L in the cooperative subframe when the subframes 3 and 4 of BCH form a third bundled frame,

It includes determining that the third PHICH resource corresponding to the third bundle frame is located in the K th subframe from the last subframe L, 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 and therefore the original subframe 8 for PHICH reception. The subframe positions in can be reused for PUSCH sent 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 one implementation, determining the PHICH group number of the PHICH resource as a function of subframe position includes:

A. Determining the I _PHICH in this embodiment of the invention is described in further detail by using the example shown in Table 12.

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

Selected from each group of frames, there are two options for each group of subframes. On the assumption that the above case exists in four groups of subframes of this configuration, there are 16 implementations for forming the I _PHICH with this configuration. In addition, the I _PHICH value corresponding to the original subframe is reused as much as possible, or the change of the I _PHICH value corresponding to the original subframe is made as small as possible. The value of I _PHICH is selected according to the rules above. For simplicity of explanation, two methods of forming the value of I _PHICH are specifically described below.
