Description

User equipment, node device and method for determining uplink timing relationship

Technical field

The present invention relates to wireless communication technologies, and in particular, to a user equipment, a node device, and a method for determining an uplink timing relationship. Background technique

Radio frame in LTE (Long Term Evolution) system and LTE-A (Advanced Long Term Research: LTE-Advanced) system includes FDD (Frequency Division Duplex) mode and TDD (Time Division Double) The frame structure of the Time Division Duplex mode. FIG. 1 is a schematic diagram of a frame structure in a related LTE/LTE-A FDD system. As shown in FIG. 1, a 10 msec (ms) radio frame consists of twenty slots of length 0.5 ms, numbered 0 to 19. Composition, time slots 2i and 2i+1 form a subframe (frame) i of length 1 ms. 2 is a schematic diagram of a frame structure in a related LTE/LTE-A TDD system. A 10 ms radio frame is composed of two half frames of 5 ms length, and one field includes five subframes of length 1 ms. Frame i is defined as two time slots 2i and 2i+1 that are 0.5 ms long.

In the above two frame structures, for the standard Cyclic Prefix, one slot contains seven symbols with a length of 66.7 microseconds (us), wherein the CP of the first symbol has a length of 5.21us, and the remaining six The CP length of the symbol is 4.69 us; for the extended cyclic prefix (Extended Cyclic Prefix), one slot contains 6 symbols, and the CP length of all symbols is 16.67 us. The supported uplink and downlink configurations are shown in Table 1:

Table 1 shows the uplink and downlink configuration table.

In the LTE system, the HARQ process refers to: When the transmitting end has data to transmit, the receiving end allocates information required for transmission, such as frequency domain resources and group information, to the transmitting end through downlink signaling. The sender sends data according to the information, and saves the data in its own buffer for retransmission. When the receiver receives the data, it detects it. If the data is received correctly, it sends an ACK (acknowledgment: Acknowledged) to send. End, after receiving the ACK, the sender clears the buffer memory used for this transmission and ends the transmission. If the data is not received correctly, a NACK (Non-acknowledged) is sent to the sender, and the packet that was not correctly received is stored in the buffer of the receiver, and the packet is sent from the receiver after receiving the NACK message. Data is presented in the flush memory and retransmitted using a particular packet format in the corresponding subframe and corresponding frequency domain locations. After receiving the retransmission packet, the receiving end merges with the previously unreceived molecules, performs detection again, and then repeats the above process until the data is correctly received or the number of transmissions exceeds the maximum transmission number threshold.

In the LTE/LTE-A FDD system, the scheduling timing of the uplink PUSCH (Physical Uplink Shared Channel) is as follows: For normal HARQ operations, The UE detects, on the subframe n, a PDCCH/EPDCCH (Downlink Control Channel/Enhanced Physical Downlink Control Channel) carrying the uplink DCI (Downlink Control Information: Downlink Control Information) or PHICH (Physical The HARQ indicator channel: Physical HARQ Indicator Channel), the UE adjusts the PUSCH transmission on the subframe n+4 according to the PDCCH/EPDCCH and the PHICH information. For the subframe binding operation, the UE detects the PDCCH carrying the uplink DCI information on the subframe n. /EPDCCH or detecting the PHICH on the subframe n-5, the UE adjusts the first PUSCH transmission in the binding in the subframe n+4 according to the PDCCH/EPDCCH and the PHICH information.

In the LTE/LTE-A TDD system, the uplink PUSCH scheduling timing is as follows: For the uplink and downlink configuration 1-6 and the normal HARQ operation, the UE detects the PDCCH/EPDCCH or PHICH transmission carrying the uplink DCI information on the subframe n, the UE Adjusting the PUSCH transmission on the subframe n+k according to the PDCCH/EPDCCH and the PHICH information; for the uplink and downlink configuration 0 and the normal HARQ operation, the UE detects the PDCCH/EPDCCH or PHICH transmission carrying the uplink DCI information on the subframe n, if the PDCCH/ The highest bit of the UL index field in the EPDCCH is 1 or the PHICH is received using the PHICH resource index 0 on the subframe n=0 or 5, and the UE adjusts the PUSCH transmission on the subframe n+k according to the PDCCH/EPDCCH and PHICH information; Row configuration 0 and normal HARQ operation, the lowest bit of the UL index field in the PDCCH/EPDCCH on the subframe n is 1 or the PHICH is received on the subframe 0 or 5 using the PHICH resource index 1 or the PHICH is received in the subframe 1 or 6 The UE adjusts the transmission of the PUSCH on the subframe n+7 according to the PDCCH/EPDCCH and the PHICH information. For the uplink and downlink configuration 0, if the highest and lowest bits of the UL index in the PDCCH/EPDCCH in the subframe n are performed, Set, then the UE transmits on PUSCH according to PDCCH / EPDCCH PHICH and information adjustment subframe n + k and n + 7, wherein k values shown in Table 2:

Table 2 shows the value table of k in different uplink and downlink configurations.

In the LTE/LTE-A TDD system, the PHICH for transmitting the HARQ-ACK response of the PUSCH in the uplink HARQ has the following timing rule, that is, the timing relationship of the uplink HARQ is as follows: For the uplink and downlink configuration 1-6, on the subframe i The PHICH channel receives the HARQ-ACK response of the PUSCH on the subframe ik; for the uplink and downlink configuration 0, the HARQ-ACK response of the PUSCH on the subframe ik is received on the PHICH resource index 0 on the subframe i; Row configuration 0, received on PHICH resource index 1 on subframe i is the HARQ-ACK response of PUSCH on subframe i-6; where k value is as shown in Table 3:

Table 3 shows the value table of k in different uplink and downlink configurations.

The most notable feature of the LTE-A system over the LTE system is that the LTE-A system introduces a carrier aggregation technique, that is, aggregates the bandwidth of the LTE system to obtain a larger bandwidth. In a system that introduces carrier aggregation, the carrier to be aggregated is called a component carrier (CC), which is also called a serving cell. At the same time, the concept of the primary component carrier/cell (PCC/PCell) and the secondary component carrier/cell (SCC/SCell) is also proposed. In the system for performing carrier aggregation, at least one primary serving cell and a secondary serving cell are included, wherein the primary serving cell is always in an active state, and the PUCCH is specified to be transmitted only on the Pcell.

4 In the LTE-A system, a cross-carrier scheduling, that is, a PDCCH on a certain serving cell, may be used to schedule a PDSCH/PUSCH of a plurality of serving cells, where a serving cell in which the PDCCH is located is called a scheduling cell, and a serving cell in which a PDSCH/PUSCH is located is called a scheduled service. Community.

The related carrier aggregation technology is only applied to the FDD serving cell or the TDD serving cell. In subsequent versions, the FDD serving cell and the TDD serving cell are considered. When the FDD serving cell and the TDD serving cell are aggregated and support cross-carrier scheduling, how is the uplink timing relationship determined? It is one of the problems to be solved, otherwise the aggregation of the FDD serving cell and the TDD serving cell cannot be realized.

It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments of the present application may be combined with each other arbitrarily. Example 1

This embodiment provides a method for determining an uplink timing relationship, including the following operations:

When the FDD serving cell and the TDD serving cell are aggregated and support cross-carrier scheduling, the device determines an uplink HARQ timing relationship of the scheduled serving cell according to the type of the scheduled serving cell;

Specifically, when determining an uplink HARQ timing relationship of the scheduled serving cell according to the type of the scheduled serving cell: if the FDD serving cell is a scheduled serving cell and the TDD serving cell is the scheduled serving cell, the UE may determine at least one of the following manners: Uplink HARQ timing relationship of the TDD serving cell:

Mode 1: The timing between the PDCCH/EPDCCH and the PUSCH on the TDD serving cell, or the timing between the PUSCH and the PHICH uses the uplink HARQ timing relationship corresponding to the FDD, and the timing between the PUSCH and the retransmitted PUSCH uses the aggregated TDD The uplink HARQ timing relationship corresponding to the serving cell;

Manner 2: The timing between the PDCCH/EPDCCH or the PHICH and the PUSCH of the TDD serving cell is the uplink HARQ timing relationship corresponding to the FDD, and the timing between the PUSCH and the retransmission PUSCH is configured with the newly configured uplink HARQ timing;

The timing between the PUSCH and the retransmitted PUSCH uses the newly configured uplink HARQ timing to refer to: an uplink HARQ timing with a timing of 10 ms between the PUSCH and the retransmitted PUSCH; the device is scheduled according to the type of the scheduled serving cell. When the uplink HARQ timing relationship of the serving cell is: If the TDD serving cell is the scheduled serving cell and the FDD serving cell is the scheduled serving cell, the uplink HARQ timing relationship of the FDD serving cell may be determined according to at least one of the following manners:

Manner 1: The uplink HARQ timing relationship between the uplink subframe of the FDD serving cell and the uplink subframe of the TDD serving cell is the same as the uplink HARQ timing of the TDD, and the uplink HARQ timing relationship on other subframes is newly defined. Uplink HARQ timing;

The uplink HARQ timing configured with the new configuration is: For the uplink and downlink configuration with the downlink-uplink transition point period of 5 ms, the newly configured uplink HARQ timing refers to the uplink HARQ that satisfies the timing between the PUSCH and the retransmitted PUSCH of 10 ms. Timing, or, for an uplink and downlink configuration of 10 ms around the downlink-uplink transition point, the newly configured uplink HARQ timing refers to satisfying the PUSCH. The timing between the retransmission of the PUSCH and the retransmission of the PUSCH is 20 ms of uplink HARQ timing.

The uplink HARQ timing with a timing of 10 ms between the PUSCH and the retransmission PUSCH refers to: detecting a PDCCH/EPDDCCH or PHICH corresponding to the PUSCH on the subframe n, and transmitting the PUSCH on the subframe n+p, in the subframe n+10. Detecting a PDCCH/EPDDCCH or PHICH corresponding to the PUSCH; where the value of p is {4, 5, 6}

Manner 2: The uplink subframe of the FDD serving cell is divided into T subframe sets, and the different subframe sets correspond to the uplink HARQ timing relationship of different TDD configurations, where T is a positive integer greater than or equal to 1;

For example, when T is 2, the subframes {2, 3, 4, 7, 8, 9} constitute a subframe set, and the uplink HARQ timing relationship of all subframes in the subframe set uses the uplink HARQ corresponding to TDD configuration 0. Timing relationship; subframes {0, 1, 5, 6} constitute another subframe set, and the uplink HARQ timing relationship of all subframes in the subframe set uses the newly configured uplink HARQ timing;

Similarly, when T is 2, the same subframe as the scheduled TDD may be divided into one subframe set, and the uplink HARQ timing relationship of all subframes in the subframe set uses the uplink HARQ timing relationship corresponding to the scheduling TDD configuration. And dividing another subframe into another subframe set, where an uplink HARQ timing relationship of all subframes in the subframe set uses a newly configured uplink HARQ timing;

When T is 3, the same subframe as the scheduled TDD may be divided into a first subframe set, and an uplink HARQ timing relationship of all subframes in the subframe set uses an uplink HARQ timing relationship corresponding to the scheduling TDD configuration; The subframes {2, 3, 4, 7, 8, 9} are divided into the second subframe set after the uplink subframe corresponding to the TDD matching, and the uplink HARQ timing of all the subframes in the subframe set.
