In the Release-5 version, high-speed downlink packet access (HSDPA) technology is introduced to improve the downlink data transmission rate and reduce the user data transmission delay, so that users can be in the UMTS network. Have a better experience. The physical channels involved in the HSDPA mainly include a downlink high-speed downlink shared physical channel (HS-PDSCH) and a corresponding downlink high-speed shared control channel (HS-SCCH, High-Speed Shared Control Channel).

For example, the slot position indication indicated by the slot position indication may be determined based on a shortest processing delay, where the shortest processing delay is a shortest time interval between the UE transmitting the channel quality indication and the base station using the channel quality indication. (The shortest time interval may include the information transmission time of the UE to the base station + the time when the base station parses the channel quality indication, etc.). In some embodiments of the present invention, the time slot position indication end time T1+the shortest processing delay T0 of the time slot in which the indicated UE sends the first indication may be earlier than the time T2 when the base station plans to use the first indication, preferably, The time slot position indication indicates that the UE indicates that the first indicated time slot end time T1 + the shortest processing time delay TO is earlier than the time T2 that the base station plans to use the first indication and is as close as possible to T2. For example, as shown in FIG. 1-b, T1 is the end time T1 of the time slot indicated by the slot indication indicated by the UE, and the base station plans to use the first indication time Τ2 (for example, a certain P-CPICH subframe will be used. The first indication), then Τ2-T1 is greater than Τ0, preferably T2-T1 is greater than TO and T2-T1 is as close as possible to T0.

In some embodiments of the present invention, the first set of time slots may include one of the above three time slots. a consecutive three time slots, including the start time slot, wherein the first time slot group among the 3N time slots corresponding to the HS-DPCCH of the system uplink carrier sends the first indication and the first downlink to the base station And transmitting, by the first time slot group of the 3N time slots corresponding to the HS-DPCCH of the system uplink carrier, sending a first downlink transmission error indication to the base station, where The remaining 2 slots in the slot group except the start slot send a first indication to the base station.

Certainly, in a special case, the first downlink transmission error indication may be sent to the base station in the last time slot of the first time slot group among the foregoing 3N time slots corresponding to the HS-DPCCH of the system uplink carrier, The remaining 2 slots in the first slot group except the last slot send a first indication to the base station.

In some embodiments of the present invention, the method may further include: transmitting, to the base station, first information in a start time slot of each of the K second time slot groups, and in each of the The remaining time slots of the second time slot group except the start time slot, send the channel quality indication newly obtained before the start time of the remaining time slot to the base station, where the K second time slot groups, a part or all of the second time slot groups among the N-1 second time slot groups divided by the remaining 3N-3 time slots except the first time slot group among the above 3N time slots, The second slot group of each of the N-1 second slot groups is three consecutive slots. It can be understood that K is a positive integer less than or equal to N-1.

For example, the first information may be a second downlink transmission error indication or fixed information (where the fixed information may be all 0s or all 1s or other fixed sequence codes, etc.) or a first downlink transmission error indication; wherein, the second indication The downlink transmission error indication is used to indicate whether the received second subframe is correctly decoded, where the second subframe is sent by the base station on the second HS-PDSCH on the second system downlink carrier, where the second The bandwidth of the downlink carrier is greater than the bandwidth of the downlink carrier of the first system, or the corresponding chip rate of the second downlink carrier is greater than the chip rate of the downlink carrier of the first system. For example, the bandwidth or chip rate of the downlink carrier of the second system may be two or four times or other multiples of the downlink carrier of the first system.

In some embodiments of the present invention, the code channel used by the UE to send the uplink feedback information corresponding to the downlink channel of the first system to the uplink feedback information corresponding to the downlink carrier of the second system may be the same or different. If the UE sends the uplink feedback information corresponding to the downlink carrier of the first system to the base station, and the code channel used by the uplink feedback information corresponding to the downlink carrier of the second system is the same, the UE indicates that the UE Transmitting the uplink feedback information corresponding to the downlink carrier of the first system and the uplink feedback information corresponding to the downlink carrier of the second system to the base station by using the multiplexed code channel; and transmitting, by the UE, the uplink feedback information corresponding to the downlink carrier of the first system, and the If the code channel used by the uplink feedback information corresponding to the downlink of the second system is different, the UE sends the uplink feedback information corresponding to the downlink carrier of the first system and the uplink feedback information corresponding to the downlink carrier of the second system to the base station. .

In some embodiments of the present invention, the method may further include: the UE transmitting, by using the same code channel that the first indication and the first downlink transmission error indication are sent to the base station, the uplink corresponding to the second system downlink carrier to the base station. Feedback.

It can be seen that, in this embodiment, for example, the UE is after receiving the first subframe sent by the base station on the first HS-PDSCH of the downlink carrier of the first system; within 3N slots corresponding to the HS-DPCCH of the uplink carrier of the system. Sending a first indication and a first downlink transmission error indication to the base station. The start time of the 3N time slots is equal to the time of receiving the first subframe plus the set duration, where the N is equal to the corresponding chip rate of the uplink carrier of the system divided by the corresponding downlink carrier of the first system. The chip rate, the above N is a positive integer greater than 1, so the UE uses the 3N time slots corresponding to the HS-DPCCH of the system uplink carrier to feed back the uplink feedback information corresponding to the downlink carrier of the first system, which is advantageous for overcoming The time difference between the system uplink carrier and the first system downlink carrier bandwidth (chip rate) is different, which is advantageous for overcoming the uplink and downlink carriers of different bandwidths (for example, the uplink carrier bandwidth is 5匪z and the downlink carrier bandwidth is 2. 5M). Or 1. 25M) is a different issue. Another embodiment of the method for transmitting feedback information according to the present invention, wherein a method for transmitting feedback information includes: transmitting a first subframe to a UE on a first HS-PDSCH on a downlink carrier of the first system; a first indication sent by the HS-DPCCH corresponding to the HS-DPCCH on the uplink carrier of the system, and a first downlink transmission error indication; wherein, the start time of the 3N time slots is equal to the first received by the UE The time of the subframe plus the set duration, the first downlink transmission positive indication is used to indicate whether the received first subframe is correctly decoded; the first indication includes a first CQI; wherein, the first CQI is based on the first The measurement result of the CPICH on the downlink carrier of the system is obtained, where the N is equal to the chip rate corresponding to the uplink carrier of the system divided by the chip rate corresponding to the downlink carrier of the first system, and the N is a positive integer greater than 1.

202. The base station receives the first indication sent by the UE in the 3N time slots corresponding to the HS-DPCCH of the system uplink carrier, and the first downlink transmission correct indication.

The start time of the 3N time slots is equal to the time when the first subframe is received plus the set duration (the set duration may be greater than or equal to 7.5 slot slots), and the first downlink transmission The positive or negative indication is used to indicate whether the received first subframe is correctly decoded; wherein the first indication includes the first CQI, or the first indication includes the first PCI and the first CQI; the first CQI is based on the first Obtaining the result of the CPICH measurement on the downlink carrier of the system, where N is equal to the chip rate corresponding to the uplink carrier of the system divided by the chip rate corresponding to the downlink carrier of the first system, and the N is a positive integer greater than 1.

The downlink transmission error indication may be ACK or NACK. The ACK indicates that the UE correctly decodes the corresponding subframe on the received HS-PDSCH. The NACK indicates that the UE does not correctly decode the corresponding subframe on the received HS-PDSCH. Of course, the downlink transmission error indication may also be other types of information indicating whether the subframe on the received HS-PDSCH is correctly decoded.

Further, in a scenario such as multiple input and multiple output (MIM0), the first indication may further include a first PCI, and the base station may perform precoding of the data to be transmitted by using a precoding matrix indicated by the first PCI fed back by the UE. operating.

In some embodiments of the present invention, the receiving the first indication and the first downlink transmission error indication in the 3N time slots corresponding to the HS-DPCCH on the system uplink carrier of the UE may include: receiving the UE In the initial time slot among the 3N time slots corresponding to the HS-DPCCH on the uplink carrier of the system, the first downlink transmission sent is positively indicated, except for the start time slot among the above 3N time slots. Specifying 2 time slots (where the designated 2 time slots may be consecutive 2 time slots or non-contiguous 2 time slots, for example, may be the last two time slots among the above 3N time slots) The first indication sent by the base station.

In another embodiment of the present invention, receiving the first indication sent by the UE in the 3N time slots corresponding to the HS-DPCCH on the uplink carrier of the system, the first indication sent by the UE and the first downlink transmission error indication may include: receiving the UE in the UE a first indication sent by the first time slot group and a first downlink transmission right error indication among the 3N time slots corresponding to the HS-DPCCH on the system uplink carrier, where the first time slot group is the foregoing 3N time slots Three consecutive time slots (such as any three consecutive time slots or a specific three consecutive time slots).

In some embodiments of the present invention, the receiving the first indication and the first downlink transmission error indication in the 3N time slots corresponding to the HS-DPCCH on the system uplink carrier of the UE may include: receiving the UE In the initial time slot of the 3N time slots corresponding to the HS-DPCCH on the uplink carrier of the system, the first downlink transmission is correctly sent, and the last two time slots among the 3N time slots are The first indication sent by the base station.

In some embodiments of the present invention, the base station may send (scheduled or aperiodic transmission) a slot position indication to the UE, so that the UE determines to send the first indicated time slot based on the slot position indication in the above 3N. The location within the time slot. For example, the slot position indication indicated by the slot position indication may be determined based on a shortest processing delay, where the shortest processing delay is a shortest time interval between the UE transmitting the channel quality indication and the base station using the channel quality indication. (The shortest time interval may include the information transmission time of the UE to the base station + the time when the base station parses the channel quality indication, etc.). In some embodiments of the present invention, the time slot position indication indicates that the indicated UE transmits the first indicated time slot end time T1+the shortest processing time delay TO, which may be earlier than the time indicated by the base station to use the first indication T2, preferably The time slot position indication end time T1 + shortest processing delay Τ 0 of the indicated time slot in which the UE transmits the first indication is earlier than the time T2 that the base station plans to use the first indication and is as close as possible to T2.

For example, the first time slot group may be three consecutive time slots including the start time slot among the above three time slots. The first indication sent by the first time slot group and the first downlink transmission error indication sent by the first time slot group corresponding to the HS-DPCCH corresponding to the UE on the uplink carrier of the system may include: receiving the UE in the system uplink The start time slot of the first time slot group among the 3N time slots corresponding to the HS-DPCCH on the carrier, the first downlink transmission error indication sent, except for the start time slot in the first time slot group of The first indication sent by the remaining 2 time slots to the base station. In addition, in a special case, the base station may also receive the first downlink transmission error indication sent by the UE in the last time slot of the first time slot group among the 3N time slots corresponding to the HS-DPCCH on the system uplink carrier. And a first indication sent to the base station by the remaining two slots except the last one slot in the first slot group.

In some embodiments of the present invention, the method may further include: receiving, by the UE, first information sent by a start time slot of each of the K second time slot groups, and each of the a remaining time slot of the second time slot group except the start time slot, and a channel quality indicator obtained based on the latest measurement result of the CPICH before the start time of the remaining time slot, where the K second The time slot group is a part or all of the N-1 second time slot groups divided by the remaining 3N-3 time slots except the first time slot group among the above 3N time slots. a time slot group, wherein each of the N-1 second time slot groups is a consecutive three time slots. It can be understood that K is a positive integer less than or equal to N-1.

In some embodiments of the present invention, the code channel used by the UE to send the uplink feedback information corresponding to the downlink channel of the first system to the uplink feedback information corresponding to the downlink carrier of the second system may be the same or different. If the UE sends the uplink information corresponding to the first system downlink carrier to the base station, and the code channel used by the uplink feedback information corresponding to the second system downlink carrier is the same, the UE sends the first to the base station by multiplexing the code channel. The uplink feedback information corresponding to the downlink carrier of the system and the uplink feedback information corresponding to the downlink carrier of the second system; if the UE sends the uplink feedback information corresponding to the downlink carrier of the first system and the uplink feedback information corresponding to the downlink carrier of the second system to the base station, If the code channels are different, the UE sends the uplink feedback information corresponding to the downlink carrier of the first system to the base station. The uplink feedback information corresponding to the downlink carrier of the second system does not reuse the code channel.

In some embodiments of the present invention, the method may further include: receiving, by the base station, uplink feedback information corresponding to the second system downlink carrier that is sent by the UE by using the same code channel as the first indication and the first downlink transmission error indication.

It can be seen that, in this embodiment, the base station sends the first subframe to the UE on the first HS-PDSCH on the downlink carrier of the first system; the receiving UE is within 3N slots corresponding to the HS-DPCCH on the uplink carrier of the system. The first indication sent and the first downlink transmission positive indication are equal to the start time of the 3N time slots, equal to the time of receiving the first subframe plus the set duration, where the N is equal to the corresponding uplink carrier of the system. The chip rate is divided by the corresponding chip rate of the downlink carrier of the first system, and the foregoing N is a positive integer greater than 1. Therefore, the UE uses the 3N time slots corresponding to the HS-DPCCH of the system uplink carrier to feed back the first system. The uplink feedback information corresponding to the carrier, which is advantageous for overcoming the slot difference problem caused by the difference between the downlink carrier of the system and the downlink carrier bandwidth (chip rate) of the first system, thereby facilitating overcoming uplink and downlink carriers of different bandwidths (for example, uplink carrier bandwidth) 5歩z and the downlink carrier bandwidth is 2. 5M or 1. 25M). In order to facilitate a better understanding and implementation of the foregoing solutions in the embodiments of the present invention, the following describes the specific application scenarios as an example.

The following is an example of a scenario in which the downlink carrier of the system includes a carrier of 5 MHz bandwidth and a non-standalone carrier with a narrow bandwidth, and the uplink carrier is a 5 MHz bandwidth carrier. For example, other similar scenarios and so on. . The length of the TTI is different because the bandwidth (chip rate) of the downlink carrier and the uplink carrier of the narrow bandwidth are different, which may cause different problems between the uplink and downlink carriers.

With reference to the uplink and downlink transmission timings in the 5 MHz bandwidth scenario, the UE feeds back the received ACK/NACK corresponding to the subframe to the base station after receiving the subframes on the HS-PDSCH for about three slots starting after 7.5 slot. When the downlink carrier bandwidth becomes 2. 5 MHz, it still keeps receiving the corresponding ACK/NACK to the base station after receiving the subframe on the HS-PDSCH. Since the uplink carrier bandwidth in the target research scenario is 5 MHz, the chip rate of the uplink feedback is faster than the chip rate on the downlink non-standalone carrier (that is, the number of transmission blocks included in a unit time). Application scenarios to describe how the present invention addresses the matching of feedback chip rates Question.

scene 1

Referring to Figure 3-a, the system uplink carrier bandwidth is 5MHz, and the system downlink carrier bandwidth is 5MHz and 2. 5MHz bandwidth.

If the uplink carrier bandwidth is 5 MHz, the physical layer chip rate is doubled with respect to the 2.5 MHz bandwidth downlink carrier, so the UE can consider ACK/NACK feedback in the earliest possible time slot, and CQI and PCI are as late as possible. The CQI and PCI information is sent by the slot, and the later the slot of the CQI and PCI is fed back, the feedback CQI may be newer (assuming that the fed back CQI is the CQI obtained based on the latest measurement result before the feedback slot arrives), which is more reflective Current channel status.

In Figure 3-a, the first slot in every 3N slots feeds back ACK/NACK, and the last two slots in 3N slots feed back CQI+PCI. Scene 2

Referring to Figure 3-b, the system uplink carrier bandwidth is 5MHz, and the system downlink carrier bandwidth is 5MHz and 2. 5MHz bandwidth. The main difference from the scenario 1 is that the uplink feedback information fed back on the two HS-DPCCHs (HS-DPCCH1 and HS-DPCCH2) in the scenario 1 is multiplexed in the scenario 2 by using code channel multiplexing. On a code track. Scene 3

Referring to Figure 3-c, the system uplink carrier bandwidth is 5MHz, and the system downlink carrier bandwidth is 5MHz and 2. 5MHz bandwidth.

If the uplink carrier bandwidth is 5 MHz, the downlink carrier of the physical layer chip rate is doubled with respect to the 2.5 MHz bandwidth. In this scenario, the UE considers to feed back ACK/NACK, CQI, and PCI in three consecutive time slots to implement uplink feedback. Subframe integrity.

For example, in Figure 3-c, the second slot in every 3N slots feeds back ACK/NACK, and the third and fourth slots in the 3N slots feed back CQI+PCI. Scene 4

As shown in Figure 3-d, the system uplink carrier bandwidth is 5 MHz, and the system downlink carrier bandwidth is 5 MHz and 2.5 MHz bandwidth. In this scenario, in order to keep the frame format unchanged, the first slot in every 3N slots is used to feed back the corresponding ACK/NACK in Figure 3-d, and the second and third slot feedback in the 3N slots. CQI+PCI. The 4th slot in the 3N slots feeds back the fixed information, and the 5th and 6th slots in the 3N slots feed back the newly obtained CQI+PCI before the time slot arrives. That is, in two uplink continuous TTIs, the previous TTI feedback indicates that the ACK/NACK of the pointer on the decoded HS-PDSCH is received, and the CQI and PCI obtained based on the latest measurement result at the time, and the fixed information is fed back in the latter TTI. And CQI and PCI based on the latest measurements at the time. In this way, the integrity of the uplink feedback subframe can be achieved, and the newer the CQI of the feedback can reflect the current channel state, and is advantageous for coding multiplexing. Scene 5

Referring to Figure 3-e, the system uplink carrier bandwidth is 5MHz, and the system downlink carrier bandwidth is 5MHz and 2. 5MHz bandwidth. The main difference from the scenario 4 is that the uplink feedback information fed back by the two HS-DPCCHs (HS-DPCCH1 and HS-DPCCH2) in the scenario 4 is multiplexed in the scenario 5 by using code channel multiplexing. On a code track. Scene 6

Referring to Figure 3-f, the system uplink carrier bandwidth is 5MHz, and the system downlink carrier bandwidth is 5MHz and 2. 5MHz bandwidth.

In this scenario, in order to keep the frame format unchanged, the first slot in every 3N slots is used to feed back the corresponding ACK/NACK in Figure 3-f, and the second and third slot feedback in the 3N slots. CQI+PCI. The information of the fourth slot feedback in the 3N slots is equivalent to the ACK/NACK of the first slot feedback, and the 5th and 6th slot in the 3N slots feedback the newly obtained CQI before the arrival of the slot. +PCI. That is, in two uplink continuous TTIs, the previous TTI feedback indicates that the ACK/NACK of the subframe error on the decoded HS-PDSCH is received, and the CQI and PCI obtained based on the latest measurement result at that time, and the fixed information is fed back in the last TTI. And the CQI and PCI information obtained at the time based on the latest measurement results. In this way, the integrity of the uplink feedback subframe can be achieved, and the newer the CQI of the feedback can reflect the current channel state, and is advantageous for coding multiplexing, and is advantageous for obtaining the time diversity gain of the ACK/NACK. Scene 7

Referring to Figure 3-g, the system uplink carrier bandwidth is 5匪 z, and the system downlink carrier bandwidth is 5MHz and 2. 5MHz bandwidth. The difference from the scenario 6 is that the uplink feedback information fed back on the two HS-DPCCHs (HS-DPCCH1 and HS-DPCCH2) in the scenario 6 is multiplexed in the scenario 7 by using code channel multiplexing. On a code track. Scene 8

Referring to Figure 3-h, the system uplink carrier bandwidth is 5匪 z, and the system downlink carrier bandwidth is 5MHz and 2. 5MHz bandwidth. The main difference from the scenario 4 is that the fixed information fed back by the scenario 4 is replaced by the ACK/NACK corresponding to the corresponding HS-PDSCH of the 5 MHz downlink carrier.

Scene 9

Referring to Figure 3-i, the system uplink carrier bandwidth is 5MHz, and the system downlink carrier bandwidth is 5MHz and 2. 5MHz bandwidth. The difference from the scenario 8 is that the uplink feedback information fed back on the two HS-DPCCHs (HS-DPCCH1 and HS-DPCCH2) in the scenario 8 is multiplexed in the scenario 9 by using code channel multiplexing. On a code track.

The above scenario is only an example. In practical applications, adaptive adjustment can also be made according to different bandwidths (chip rates) and the like.
