Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an information processing method and apparatus in a communication system.
Background
A communication system may have one or more network nodes (nodes) and User Equipment (UE) in communication. After the UE is powered on, in order to access the network, at least one network node must be found and accessed through the network node. If one network includes multiple network nodes, the UE may be accessible through any one of the multiple network nodes.
Taking a cellular system as an example, one network node is configured as one cell (cell), each cell transmitting a different signal. The UE detects signals of different cells, identifies a suitable cell and accesses the network, and this process is called initial access. In a cellular system, in addition to cell identification (finding a suitable network node for access) during initial access, the UE may also need to perform cell identification during cell reselection or in a connected state, identify a suitable cell for camping on, or report a handover request to a base station.
An LTE (Long Term Evolution ) system carries identification information of a cell through a synchronization Signal (SYNC). Synchronization signals of the LTE system include a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS). The base station of the cell may have one or more transmit antennas, and the PSS/SSS is transmitted over multiple antennas after being shaped. Since the PSS/SSS signals are designed for access by all users in a cell, the design of the beamforming scheme should ensure wide beamforming. In this way, the PSS/SSS may be received by all users within the cell. Therefore, a cell transmits a PSS/SSS signal, which has a one-to-one correspondence with a cell ID (cell identity) of the cell. And after detecting the PSS/SSS of a Cell, the UE correspondingly obtains the Cell ID of the Cell, and further identifies the Cell. In the LTE system, the PSS/SSS has a bandwidth of 6PRB (physical resource block), and is limited to be transmitted in the center of the bandwidth of each cell.
The existing communication system mainly focuses on low-frequency band deployment, and the number of antennas at a node side is small; future communication systems will be deployed over large bandwidths of 0.4 GHz-100 GHz. The channel performance difference between the low frequency band and the high frequency band is very large, the path loss of the high frequency band is much higher than that of the low frequency band, and the cell coverage is reduced sharply, so that new synchronization and initial access signal design are required to ensure sufficient network coverage.
There may be multiple TRPs (Transmit or receive points) in a cell of a future network, and each TRP is identified by a different ID. In addition, the number of antennas of a future communication system will increase dramatically to hundreds or even thousands, a large number of antennas can generate narrow shaped beams by using a shaping technology, and beam gain can improve the intra-beam coverage. However, because the beams are narrowed, the angle that each beam can cover is small, and the cell needs a plurality of beams to point to different directions, so as to achieve the coverage of the whole cell. Therefore, synchronization and initial access signal design for future communication systems needs to take into account the impact of these deployments. The scheme of transmitting one PSS/SSS per cell is not enough to provide sufficient coverage for the cell, nor is the limitation of PSS/SSS being transmitted in the center of the cell bandwidth sufficient to meet the flexibility requirement of coverage.
Since there may be a plurality of TRPs in a cell in a future communication system, a terminal needs to receive a large amount of synchronization signals of the TRPs and even system information, which causes a terminal search process to become very complicated, thereby increasing power consumption of the terminal.

Detailed Description
The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
As shown in fig. 1, an information processing method in a communication system according to a first embodiment of the present invention is applied to a transceiver node on a network side. In the embodiment of the present invention, the communication system includes a plurality of transceiving nodes, and each transceiving node transmits one or more pieces of synchronization signal information. The method comprises the following steps:
step 101, a first transceiving node receives synchronization signal information of a neighboring transceiving node.
As mentioned above, the communication system comprises a plurality of transceiving nodes. The transceiver node includes, but is not limited to, a base station on the network side, and other devices.
In the embodiment of the present invention, the first transceiving node refers to any node in a communication system. For example, the first transceiving node may be a base station or the like to which the terminal is connected. In a particular application, the first transceiving node may designate other transceiving nodes in the network as neighboring transceiving nodes. For example, the first transceiving node may be selected according to the distances between other transceiving nodes and it. For example, the first transceiving node may select a node closer to the first transceiving node as the neighboring transceiving node, for example, the first transceiving node may select a transceiving node within a distance of 200m as the neighboring transceiving node, and so on. Also for example, it is assumed that the first transceiving node may operate on multiple frequencies, such as frequency a, frequency B, etc. If a first transceiving node operates on frequency a, it may designate the first transceiving node as a neighboring transceiving node thereto when operating on frequency B. Of course, the first transceiver node may also designate other transceiver nodes as neighboring transceiver nodes herein in other manners, which are not limited in the embodiments of the present invention.
Wherein the synchronization signal information includes: the frequency domain position of the synchronization signal or the offset of the synchronization signal with respect to the center frequency. In order to further reduce the power consumption of the terminal, any combination of the following information can be further included in the synchronization signal information: synchronization and/or scrambling sequences, a transmission time window of said synchronization signal.
In a specific application, the first transceiving node receives synchronization signal information sent by a preset transceiving node, and the first transceiving node selects a neighboring transceiving node from the preset transceiving node, where the neighboring transceiving node is a transceiving node designated by the first transceiving node. Then, the first transceiving node acquires the synchronization signal information of the adjacent transceiving node from the synchronization signal information sent by the preset transceiving node. The preset receiving node refers to part or all of transceiving nodes in a network.
And 102, the first transceiving node sends the synchronization signal information to a terminal.
Specifically, in this step, the first transceiving node transmits the synchronization signal information to the terminal on one or more carriers. The first transceiving node may also send said synchronization signal information to the terminal on the primary carrier if the first transceiving node determines that the terminal is operating on a non-primary carrier.
As can be seen from the above, in the embodiment of the present invention, when a plurality of transceiving nodes exist in a communication system and each node transmits one or more pieces of synchronization signal information, the first transceiving node transmits synchronization signal information of its neighboring transceiving nodes to a terminal. Because the number of the adjacent transmitting and receiving nodes is less than that of the transmitting and receiving nodes in the communication system, the terminal does not need to search the required synchronous signals in the received information of the plurality of synchronous signals, so that the terminal can quickly find the required synchronous signals, and the power consumption is reduced.
As shown in fig. 2, a second information processing method in a communication system according to an embodiment of the present invention is applied to a terminal. The communication system includes a plurality of transceiving nodes, each of which transmits one or more synchronization signal messages. The method comprises the following steps:
step 201, receiving synchronization signal information of a neighboring transceiving node of a first transceiving node sent by the first transceiving node.
Wherein, the meaning of the synchronization signal information can refer to the description of the first embodiment. In this step, the terminal receives, on one or more carriers, synchronization signal information of neighboring transceiving nodes of a first transceiving node transmitted by the first transceiving node. If the terminal works on the non-main carrier, the terminal receives the synchronization signal information of the adjacent transceiving nodes of the first transceiving node, which is sent by the first transceiving node, on the main carrier.
Step 202, obtaining the synchronization signal of the target transceiving node according to the synchronization signal information of the adjacent transceiving node and the preset information of the target transceiving node.
In this step, the predetermined target transceiving node refers to a transceiving node to which the terminal intends to connect. For example, when the terminal finds that the signal of the receiving and sending node a is strong while moving, the receiving node a can be used as a target receiving and sending node. The information of the target transceiving node may be an identity, an address, etc. of the transceiving node.
In this step, in the received synchronization signal information of the neighboring transceiving node, the preset information of the target transceiving node is used for searching, and the synchronization signal of the target transceiving node is obtained.
As can be seen from the above, in the embodiment of the present invention, when a plurality of transceiving nodes exist in a communication system and each node transmits one or more pieces of synchronization signal information, the first transceiving node transmits synchronization signal information of its neighboring transceiving nodes to a terminal. Because the number of the adjacent transmitting and receiving nodes is less than that of the transmitting and receiving nodes in the communication system, the terminal does not need to search the required synchronous signals in the received information of the plurality of synchronous signals, so that the terminal can quickly find the required synchronous signals, and the power consumption is reduced.

And 305, the terminal receives the synchronization signal information of the first transceiving node, and acquires the synchronization signal of the target transceiving node according to the synchronization signal information and preset information of the target transceiving node.

And step 306, the terminal receives the system information of the first transceiving node, and acquires the system information of the target transceiving node according to the system information and the preset information of the target transceiving node.
In this step, the terminal receives, on one or more carriers, system information of neighbouring transceiving nodes of a first transceiving node transmitted by said first transceiving node. If the terminal works on the non-main carrier, the terminal receives the system information of the first transceiving node sent by the first transceiving node on the main carrier.
Here, the terminal acquires the synchronization signal of the target transceiving node according to the synchronization signal information of the neighboring transceiving node and preset information of the target transceiving node, and acquires the system information of the target transceiving node according to the system information of the neighboring transceiving node and the information of the target transceiving node.
As can be seen from the above, in the embodiment of the present invention, when a plurality of transceiving nodes exist in a communication system and each node transmits one or more pieces of synchronization signal information, the first transceiving node transmits synchronization signal information and system information of its neighboring transceiving nodes to a terminal. Because the number of the adjacent transmitting and receiving nodes is less than that of the transmitting and receiving nodes in the communication system, the terminal does not need to search the required synchronous signals and system information in the received synchronous signal information, so that the terminal can quickly find the required synchronous signals and system information, and the power consumption is reduced.

Further, the association information may further include a synchronization sequence and/or a scrambling sequence. Wherein the system information reference information comprises any combination of the following information: frequency domain information sent by the system information, time domain information sent by the system information, and pilot frequency information corresponding to the system information.

Wherein the description of step 404 can refer to the description of step 102 in the first embodiment.
Step 405, the first transceiving node sends the system information to the terminal.
Specifically, the first transceiving node transmits the system information to the terminal on one or more carriers. And when the terminal works on a non-main carrier, the first transceiving node sends the system information to the terminal on a main carrier.

And step 408, the terminal receives the system information and the associated information of the first transceiving node, and the terminal acquires the system information of the target transceiving node from the system information of the adjacent transceiving node according to the associated information, the synchronization signal information and the information of the target transceiving node.

And if the terminal works on the non-main carrier, the terminal receives the system information and the associated information of the first transceiving node sent by the first transceiving node on the main carrier.
Because the associated information is obtained, compared with the embodiment, the scheme of the embodiment of the invention can enable the terminal to obtain the system information of the target transceiving node more quickly.
As can be seen from the above, in the embodiment of the present invention, when a plurality of transceiving nodes exist in a communication system and each node transmits one or more pieces of synchronization signal information, the first transceiving node transmits synchronization signal information and system information of its neighboring transceiving nodes to a terminal.
