Description

The present invention relates to the field of communications technologies, and in particular, to a method, device, and system for configuring signaling resources.

Background technique

In the Long Term Evolution (LTE) system, some of the wireless bands are used for signal transmission. The time and frequency occupied by the signal transmission of the LTE system is called time-frequency resource. In an LTE system, time-frequency resources are time-divided into frames of different lengths such as a frame, a subframe, and an Orthogonal Frequency Division Multiplexing (OFDM) symbol, where one frame The duration is 10ms, one frame contains 10 subframes, and one subframe time is 1 ms. One subframe can be divided into two slots (slots), and each slot is divided into multiple OFDM symbols. Here, in the frequency domain structure of one subframe, the system bandwidth occupied by LTE is divided into units called a resource block PRB pair (Physical Resource Block Pair). For example, if the system bandwidth is 10 MHz, one subframe is divided into 50 PRB pair units in the frequency domain, and each PRB is divided into multiple resource units RE (Resource Element). In the LTE system, multiple channels and reference signals need to be transmitted on the time-frequency resources. One of the control channels uses the physical downlink control channel PDCCH (Physical Downlink Control Channel) as an example, and the reference signal uses the cell common reference signal CRS (Cell-specific). Reference Signal) is an example.

The channel transmitted in the LTE system further includes an enhanced control channel EPDCCH (Enhanced PDCCH), which is different from the PDCCH in that the PDCCH uses the first 1-4 OFDM symbols of one subframe, and the EPDCCH uses the first 1-4 symbols. OFDM symbols outside the OFDM symbol, and the PDCCH is occupied by the entire system bandwidth, and the EPDCCH uses only a few PRB pairs. In the LTE system, in order to use the EPDCCH, one base station can configure the UE (User Equipment) 1 to 2 EPDCCH set sets, each EPDCCH set includes several PRB pairs. Here, the base station will inform the UE which number of PRB pairs each EPDCCH set occupies. The Downlink Control Information (DCI) sent to a UE is sent in some PRB pairs in the EPDCCH set configured for this UE. In order to help the UE to know which REs the EPDCCH is transmitting, the base station uses the high layer signaling to indicate the resource mapping information of each EPDCCH set of the UE, including: the number of PRBs included in the set, and the specific number of the set PRBs, The RE information in set that cannot be used due to the transmission of CRS and the number of starting OFDM symbols of this set. After the UE obtains the resource mapping information of each EPDCCH set, the EPDCCH is correctly demodulated and received. When resource mapping is performed on the EPDCCH in the prior art, the PDCCH and the CRS appear in each subframe in the resource mapping manner. In the prior art, the PDCCH and the CRS are fixed only in certain subframes (for example, subframes 0 and 5 in each frame), and the remaining PDCCHs and CRSs will be in the Downlink DTX (downlink discontinuous transmission). Random occurrences in the remaining sub-frames. If only the CRS information that needs to be avoided and the number of starting OFDM symbols of the current set are mapped to the EPDCCH according to the current technology, the current subframe set indicated by the high layer signaling of the base station is mapped to the EPDCCH. The EPDCCH resource mapping cannot be matched, causing the problem that the EPDCCH cannot be correctly received.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. Some embodiments, but not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. The invention provides a method for configuring signaling resources, which is suitable for long-term evolution

In the LTE (Long Term Evolution) system, the time and frequency occupied by the signal transmission of the LTE system is called time-frequency resource, and the reference signal is also transmitted on the time-frequency resource, and the transmission of the reference signal is mainly used for Receiver demodulation, channel estimation, etc.; in addition, time-frequency resources are also used to transmit various channels, including data channels and control channels. A control channel is called a Physical Downlink Control Channel (PDCCH), and a reference signal is called a Cell-specific Reference Signal (CRS). The channel transmitted in the LTE system further includes an enhancement. The EPDCCH (Enhanced PDCCH) is also used to transmit downlink control signaling compared to the PDCCH described above. However, the time-frequency resource used by the EPDCCH is different from the PDCCH. The PDCCH uses the first 1-4 of one subframe. OFDM symbols, and EPDCCH will use the following OFDM symbols. The PDCCH is the entire system bandwidth, and the EPDCCH only occupies several PRB pairs (Physical Resource Block Pairs) in the entire system bandwidth. And the OFDM symbol exists in each subframe, so once the UE receives the resource mapping information of the EPDCCH set, the EPDCCH resource mapping is performed according to the configuration here in all the subframes, and in the downlink intermittent transmission Downlink DTX. , the CRS and PDCCH of each subframe are different. If only According to the prior art, according to the current subframe set set indicated by the high layer signaling of the base station, the CRS information to be avoided and the initial set OFDM symbol number of the current set are used to perform resource mapping on the EPDCCH, and then mapped to the actual EPDCCH resource in the partial subframe. The problem is that the EPDCCH cannot be correctly received. Therefore, the embodiment of the present invention provides a method for configuring a signaling resource. The base station side, as shown in FIG. 1 , specifically includes the following steps:

Here, the base station configures a resource mapping for the EPDCCH for the user equipment UE (User Equipment) according to different subframes. Specifically, the EPDCCH configuration parameters are respectively configured according to different subframes: the configuration information of the CRS and the PDCCH in each subframe is a resource mapping of the EPDCCH, and the configuration information of the CRS and the PDCCH can prevent the UE from occupying the CRS when receiving the EPDCCH. Or the resource unit RE ( Resource Element ) occupied by the PDCCH, so that the EPDCCH is correctly received. Here, in the frequency domain structure of one subframe, the system bandwidth occupied by LTE is divided into units called a resource block (PB) (Physical Resource Block Pair). For example, if the system bandwidth is 10 MHz, one subframe of the cell is divided into units of 50 PRB pairs in the frequency domain, and each PRB is divided into multiple resource units RE (Resource Element). The PDCCH uses the first 1 to 4 OFDM symbols of one subframe, and the EPDCCH uses the OFDM symbols except the first 1 to 4 OFDM symbols, and the PDCCH is used to occupy the entire system bandwidth, and the EPDCCH only uses a number of OFDM symbols. PRB pair.

The base station sends the resource indication information of the EPDCCH to the user equipment, and the user equipment is instructed to determine, according to the resource indication information of the EPDCCH, the resource unit used for transmitting the EPDCCH in each subframe signaling resource. The method for configuring the signaling resource provided by the embodiment of the present invention, the base station generates the resource indication information of the enhanced enhanced physical downlink control channel EPDCCH according to the CRS and the configuration parameters of the PDCCH in different subframes, so that the user equipment is enhanced according to the enhancement type. The resource indication information of the physical downlink control channel EPDCCH determines the resource unit RE used for transmitting the EPDCCH in the signaling resource. The problem that the EPDCCH cannot be accurately mapped due to the inability to accurately transmit the EPDCCH is solved.

Specifically, the user equipment configures resource mapping for the enhanced physical downlink control channel EPDCCH according to the resource indication information of the EPDCCH, and the specific steps are as follows:

a. When the PDCCH has only the first subframe set in the resource indication information of the received EPDCCH, the EPDCCH is received according to the resource indication information of the EPDCCH.

The number of subframes in the first subframe set occupied by the PDCCH in the resource indication information of the EPDCCH, and the number of start symbols of the OFDM symbol occupied by the PDCCH. It is assumed here that the PDCCH is present in the 0th subframe and the 5th subframe, and the other subframes are not included in the 0th subframe and the 5th subframe, and the subframe is located according to the PDCCH (eg, the PDCCH is located in the 0th subframe and the PDCCH) 5 subframes), the number of starting symbols occupied by the PDCCH in the PRB pair in one subframe, and the resource mapping is configured for the EPDCCH. Since the number of starting symbols of the PDCCH is known to be OFDM, the same subframe is used according to the existing regulations.

When the base station configures resource mapping for multiple EPDCCH sets, the base station determines that there are CRS and PDCCH in the 0th subframe and the 5th subframe, and then configures the 0th EPDCCH. The CRS and the PDCCH are configured in both the 0th subframe and the 5th subframe in the set set and the 1st EPDCCH set set. Therefore, when the user equipment receives the EPDCCH corresponding to the PDCCH and the CRS generated according to the determination of the presence of the CRS and the PDCCH on the 0th subframe and the 5th subframe, When the resource indication information is used, the resource mapping of the EPDCCH is configured according to the resource indication information of the EPDCCH.

If it is determined in at least one subframe that the CRS and the PDCCH are not included, all subframes are not set in the subframe information.

Assuming that the base station determines that there is no CRS and PDCCH on all subframes except the 0th subframe and the 5th subframe, the CES and the PDCCH are not configured in the OEPDCCH set set and the other subframes in the 1st EPDCCH set set. Therefore, when the user equipment receives the resource indication information of the EPDCCH corresponding to the CPDCCH and the PDCCH generated in the other subframes except the 0th subframe and the 5th subframe, the EPDCCH is determined according to the EPDCCH. The resource indication information configures a resource mapping of the EPDCCH.

If the CRS and the PDCCH are not included in the at least one subframe, the user equipment does not have the CRS and the PDCCH on each EPDCCH set received according to the resource indication information of the EPDCCH.

Cl. If it is not determined in the other subframe whether the CRS and the PDCCH are included, at least one other subframe is set in the subframe information, and at least one other subframe is not set in the subframe information. It is assumed here that the base station cannot determine whether there is a CRS or a PDCCH except for the subframes other than the 0th subframe and the 5th subframe, and it is assumed that the CRS and the PDCCH exist in the 0th subframe set, and the subframe does not exist in the first subframe set. .

The PDCCH and the CRS are present in the frame, and the PDCCH and the CRS are not present in the other subframes except for the PDCCH and the CRS in the 0th subframe and the 5th subframe in the 1st EPDCCH set. If the base station decides to transmit the PDCCH and the CRS in other subframes in addition to the 0th subframe and the 5th subframe, the OEPDCCH set set shown in Table 1 is used, and the OEPDCCH set is transmitted to transmit the PDCCH and the CRS in the user. On the device side, the PDCCH and the CRS are transmitted on the 0 to 9 subframes to avoid occupying 0 to 9 when performing resource mapping configuration on the EPDCCH. The resources occupied by the PDCCH and CRS on the subframe. When the base station determines that there is no PDCCH and CRS in other subframes except the 0th subframe and the 5th subframe, the 1st EPDCCH set set shown in Table 1 is used, and the 0th subframe in the 1st EPDCCH set set is used. The PDCCH and the CRS are transmitted in the 5th subframe, and the PDCCH and the CRS are not in the other subframes. On the user equipment side, the EPDCCH is received according to the case where the PDCCH and the CRS are not transmitted on the 0 to 9 subframes, thereby enabling the user equipment to be correct.
