Description

Super cell uplink data joint processing method and system thereof

The present invention relates to an access network in the field of wireless communications, and in particular, to a super cell uplink data joint processing method and system thereof. Background technique

When the radio access network is in the same frequency group, in the downlink direction, the common channel of the cell overlaps in the time domain and the frequency domain, and the downlink common channel of the user equipment (UE, User Equipment) located at the edge of the cell is severely affected by the cell. Inter-interference, and such interference cannot be solved by interference coordination; in the uplink direction, the channel transmitted by the UE with a larger transmission power causes interference to the same channel of the neighboring cell.

Under the wireless communication protocol, in order to solve inter-cell interference and improve network performance, different cells are aggregated to form one super cell, and the super cell is treated by using multiple cells as one cell, and the coverage of each cell is called The sub-area, the base station covering each sub-area belongs to the same cell. Since the split wireless network is generally based on the indoor baseband processing unit (BBU) + radio remote unit (RRU) architecture, the processing capability of one BBU baseband board can support multiple cells, so After forming a super cell, a cell sub-unit physically corresponds to an RRU, or a group of distributed antennas, that is, a transceiver or antenna of a cell is turned into a distributed transceiver or antenna, as shown in the figure. La is shown.

For the same terminal, in the whole system, the uplink data is likely to be received also at multiple receivers. In the processing of the super cell, due to the non-common local oscillation between multiple receivers, the data between the multiple receivers in the uplink is caused.

The former method is mainly employed in the present embodiment, and is described in conjunction with the specific embodiments and the drawings.

Based on the above-mentioned joint processing system for the uplink data of the super cell and the super cell, the present embodiment further provides an uplink data joint processing method for the super cell.

Referring to FIG. 5, it is a flowchart of an embodiment of a super cell uplink data joint processing method according to an embodiment of the present invention. The super cell uplink data joint processing method in this embodiment includes:

S501: Perform pre-processing on the input antenna data.

Here, the pre-processing in the present embodiment mainly performs appropriate processing on the input antenna data to become data suitable for channel estimation, and different protocols have different processing here.

S503. Obtain scheduling information and an active set of all UEs.

Of course, obtaining the active set in this embodiment may also be performed after channel estimation is performed on all channels of each transceiver of each UE.

S505: Perform channel estimation on each channel of all UE corresponding transceivers. In this embodiment, channel estimation is performed for each channel, that is, the channel weight of each channel, the transmission power of the antenna, the channel noise, and the like are measured for use in channel equalization.

S507: Perform joint processing on the uplink data to be processed corresponding to all UEs according to the acquired scheduling information and the active set.

S509. Output a joint processing result, that is, the corresponding single cell data of the UE.

S511, post processing.

The post-processing in this embodiment processes the soft bits after soft demodulation and makes the final hard decision as the final information bits.

Please refer to FIG. 6, which is a flowchart of an embodiment of step S507 of the present embodiment. Step S507 of this embodiment includes:

S601. Acquire an active set of the currently pending UE.

S603. Acquire, according to the acquired scheduling information, the current pending uplink data corresponding to the current UE to be processed.

S605. Perform joint processing on the current pending uplink data corresponding to the current active UE to be processed, to obtain one-way single-cell data of the current UE to be processed.

S607. Determine whether all UEs have been processed. If yes, go to step S509. Otherwise, go to step S601.

In this embodiment, the active set of the current to-be-processed UE is obtained, and the corresponding uplink processing of the uplink data to be processed is performed according to the active set. After the uplink data is obtained, the corresponding uplink data to be processed is separately processed according to the respective activation sets.

Since the UE itself may have multi-user multiple-input multiple-output (MU-MIMO, Multi-User MIMO) paired UEs, the activation sets of the two are the same, and since there is no distinction, when the data joint processing is performed, the same transmission and reception will be performed. The uplink data received by the letter machine is subjected to repeated joint processing, thereby increasing the overhead of the system. In order to reduce the overhead of the system, the embodiment is in step S605. Previously, it also included the steps:

Determining whether there is a MU-MIMO paired UE in the current UE to be processed, and if yes, acquiring scheduling information of the MU-MIMO paired UE, and the activation set of the UE constituting the MU-MIMO pairing is the same; otherwise, according to the current UE to be processed The active set and the corresponding bandwidth information are obtained to obtain uplink data corresponding to the to-be-processed channel. The scheduling information includes bandwidth information and the like.

After acquiring the scheduling information of the MU-MIMO paired UE, acquiring the to-be-processed uplink data on the to-be-processed channel according to the active set of the currently-to-be-processed UE and the corresponding bandwidth information; performing MU-MIMO on the acquired uplink data to be processed The channel is equalized, and the data of the two UEs are simultaneously output from one channel of data.

It is determined whether all the UEs to be processed have been processed. If not, it continues to determine whether the UE to be processed has the MU-MIMO paired UE, and performs the same processing as described above until all UEs have processed.

The method for jointly processing uplink data of the super cell in this embodiment obtains an active set of the UE, acquires uplink data on the corresponding pending channel according to the active set of the UE, and performs the obtained uplink data as a single user. The channel equalization ensures that the data sent to the upper layer has only one single cell data, so that the channel condition is very good, and the frequency offset of each transceiver in the active set of the UE is not much different, and the channel is very good. The combined gain, which in turn increases the efficiency of the system.

Since the number of transceivers in the super cell is large and the total number of antennas is large, the overhead of the system is very large, resulting in poor system achievability. In this case, since the update period of the active set is relatively long, and the decision condition of the active set is relatively loose, the physical layer performs the super cell uplink joint processing, and the condition on the channel changes due to the fading on the channel. Moreover, the power of the same UE received on each transceiver is different, and some transceivers receive relatively small power, so that the transceivers belonging to the active set are likely to contribute little to the demodulation. Therefore, it can be discarded during demodulation to obtain a subset of the corresponding active set. That is, demodulation set. Therefore, in order to reduce the system overhead without degrading the system performance, the embodiment further proposes a demodulation set, which is a subset of the active set, and performs data joint processing according to the demodulation set, thereby effectively reducing The number of transceivers and antennas involved in data joint processing, thereby reducing system overhead.

Referring to FIG. 7, a flowchart of still another embodiment of step S507 of the uplink data joint processing method of the present embodiment:

S701. Acquire channel estimation results of all channels of the active centralized transceivers of all the UEs to be processed, and determine, according to the channel estimation result, respective demodulation sets of the to-be-processed UEs.

Here, the active set in this embodiment belongs to a set of transceivers that are stable for a relatively long time, so the condition for determination is relatively loose, and the demodulation set of the UE is relatively fast due to changes in channel conditions, so each demodulation is performed. Both need to recalculate the decision, and the demodulation set is a subset of the active set. In the present embodiment, the demodulation set is determined according to the channel estimation result of each channel in the UE active set, and the specified number of channel conditions (the set number of transceivers to be set) that activates the centralized transceiver are transmitted and received. The signal is selected as a to-be-processed set. If the number of to-be-processed antennas corresponding to the transceiver of the to-be-processed set is greater than the set processing capability (pre-set number of antenna thresholds), further selected from the to-be-processed set The transceiver selects the antenna with the best channel condition of the specified number (that is, the preset antenna number threshold) as the demodulation set, and finally performs the joint processing of the uplink data of the designated UE according to the demodulation set.
