- the time domain in the system is composed of radio frames, and the radio frames pass through the system.
- one subframe is identified by the system frame number and the subframe number within each radio frame.
- the subframes mentioned below are the same.
- the current TDD system supports seven kinds of uplink and downlink ratios.
- the specific configuration of each uplink and downlink ratio is as follows:
- U is represented as an uplink subframe
- D is a downlink subframe
- S is a special subframe, which is mainly used for downlink transmission.
- the special subframe and the downlink subframe are collectively referred to as a downlink subframe. It can be seen from the description of the above radio frame that the subframe having the subframe number of 0-9 constitutes one radio frame.
- the system notifies the current uplink and downlink ratio by broadcast information, and changes the ratio once in 640 milliseconds (ms).
- ms milliseconds
- the system can dynamically notify different uplink and downlink ratios.
- the HARQ timing refers to the transmission timing relationship between the PDSCH (PDSCH scheduled by the PDCCH, the PDCCH and the PDSCH are transmitted in the same downlink subframe) and the HARQ feedback information, or further includes the downlink semi-persistent scheduling and decoding PDCCH confirmation (SPS) Release PDCCH Validation, Semi-Persistent Scheduling Release PDCCH Validation)
- SPS downlink semi-persistent scheduling and decoding PDCCH confirmation
- the transmission timing relationship between signaling (which can be simply referred to as downlink SPS translation signaling) and HARQ feedback information.
- the "different HARQ timing" of TDD includes two cases: First, the number of HARQ timings defined by different uplink and downlink ratios is different. For example, the ratio 0 defines the HARQ timing of four downlink subframes.
- Ratio 1 defines the HARQ timing of the six downlink subframes; second, the same downlink subframe (refers to having the same uplink and downlink ratio 0, and the downlink subframe 0 of the HARQ feedback information is transmitted on the uplink subframe 4, in the uplink and downlink In the case of the ratio 1, the HARQ feedback information of the downlink subframe 0 is transmitted on the uplink subframe 7. Specifically, the base station transmits the PDSCH or the downlink SPS to the UE in the downlink subframe, and the UE is in the uplink subframe. The HARQ feedback information of the PDSCH or the downlink SPS release PDCCH acknowledgement signaling is sent to the base station on the frame n .
- the downlink subframe may be briefly described as being associated with the uplink subframe.
- - the first subframe of the uplink subframe n forward (ie, early), that is, in chronological order, first the downlink subframe "- appears, then counts to the first subframe as the uplink subframe, where k ⁇ K, is a

- Up and down ratio different uplinks It can be determined on different downlink associated set.
- the HARQ timing under each uplink-downlink ratio can be determined accordingly, as shown in the following table.
- the uplink subframe with the subframe number 2 is used to transmit the sixth subframe of the previous number, that is, the HARQ feedback information of the downlink subframe with the subframe number of the previous radio frame is 6. Therefore, the downlink subframe with the subframe number of 6 of the previous radio frame is associated with the subframe number of the current radio frame is 2.
- the uplink subframe, that is, the PUCCH resource region must be allocated for the downlink subframe with the subframe number of the previous radio frame of 6 in the uplink subframe with the subframe number 2 of the current radio frame.
- the uplink subframe with the subframe number 2 is used to transmit the 6th subframe of the previous number and the 7th subframe of the previous number, that is, the subframe number of the previous radio frame is 6.
- the HARQ feedback information of the downlink subframe with the subframe number of 5 so the downlink subframe of the previous radio frame with the subframe number of 6 and the subframe number of 5 is associated with the subframe number of the current radio frame of 2.
- the uplink subframe, that is, the uplink subframe with the subframe number 2 of the current radio frame must allocate the PUCCH resource region for the downlink subframe with the subframe number of the previous radio frame of 6 and the subframe number of 5.
- the PUCCH resource determining process on the uplink subframe is:
- the frequency domain size that is, the number of subcarriers included, is one element in the downlink association set on the uplink subframe, and is the associated region index, that is, the downlink subframe in the downlink subframe set is in the downlink subframe set.
- «PU3 ⁇ 4CH (Mm- ⁇ ) - N c + mN c + x + n CCE + 1 + N ⁇ CCH .
- W[ CCH is configured by higher layer signaling
- M is the number of elements in the downlink association set, that is, the number of elements in the downlink subframe set.
- Each DL subframe is configured with multiple CCEs, and different CCEs correspond to different PUCCH resources. Therefore, multiple PUCCH resources are reserved for the associated DL subframes in one UL subframe, and these multiple PUCCH resources are composed.
- a PUCCH area is reserved, that is, one PUCCH resource area is reserved for its associated DL subframe on one UL subframe. It can be seen from the above process that when different times, that is, for different downlink subframes, the reserved PUCCH resource regions are different.
- control channel on each downlink subframe is divided into C block regions, and correspondingly, the PUCCH resource region corresponding to each downlink subframe is also divided into C blocks, when multiple downlink subframes are associated with one In an uplink subframe, the PUCCH resource regions corresponding to the multiple downlink subframes are staggered, as illustrated in FIG. 1 .
- the old version UE adopts the uplink and downlink ratio 0, and the subframe number of the current radio frame is 2.
- the PUCCH resource region is allocated to the downlink subframe with the subframe number of the previous radio frame of 6.
- the new version of the UE adopts the uplink and downlink ratio 1 and the uplink subframe of the subframe of the current radio frame is 2.

- the sequence number of the downlink subframe with subframe number 5 is 0,
- the sequence number of the downlink subframe with subframe number 6 is 1.
- the other parameters of the formula are the same, only ⁇ / and are different. Therefore, the result of the allocation is as shown in the figure, and the PUCCH resource area allocated to the two versions of the UE may be aliased. In this way, the base station needs to allocate different PUCCH resources from the aliased PUCCH resource region to configure different versions of the UE, which inevitably increases the complexity of the PDCCH scheduling algorithm, thereby causing the base station to operate at a lower efficiency.
- a resource configuration method may be provided.
- the PUCCH resource region of the second group of UEs is offset, so that the second group of PUCCH resource regions and the first group are The PUCCH resource area is completely staggered.

- the determining of the second PUCCH resource region may include two steps, step S1051 and step S1053:
- the base station determines 2 and 2 is the number of elements in the second downlink subframe set, and is the sequence number of the downlink subframe in the second downlink subframe set in the second downlink subframe set.
- the base station determines an offset of the second PUCCH resource region, where the offset is such that the PUCCH resource region allocated for the second downlink subframe set is completely offset from the PUCCH resource region allocated for the first group of UEs.
- the method for determining the offset is to make the offset equal to the number of downlink subframes associated with the first uplink subframe in the first uplink-downlink ratio, and multiply by the maximum configurable on one downlink subframe.
- the maximum number of OFDM symbols included in a PDCCH resource region corresponding to one downlink subframe may be 3 or 4, which is determined by the bandwidth of the system. When the bandwidth is large, the maximum number of symbols may be 3. When the bandwidth is small, the maximum is The number of symbols may be 4.

- the second downlink subframe set may include two types of subframes: one is a downlink subframe in which a PDCCH region is configured; and the other is a downlink subframe in which a PDCCH region is not configured.
- a downlink subframe in which the PDCCH region is not configured there are two cases: 1.
- the ePDCCH resource to the PUCCH according to the existing scheme.
- the mapping rule of the resource reserves the PUCCH resource; 2.
- the fake downlink subframe is currently configured as an uplink subframe or an empty subframe.
- the ratio cannot be Really indicating uplink and downlink subframe allocation, therefore, some subframes in the second downlink subframe set may be configured as uplink subframes or not transmitting data.
