Description

Paging transmission method, communication station and communication node under uplink mobility

Technical field

The embodiments of the present invention relate to, but are not limited to, the field of communication technologies, and in particular, to a paging transmission method, a communication station, and a communication node in uplink mobility.

Background technique

With the continuous advancement of radio technology, a variety of radio services have emerged, and the spectrum resources supported by the radio service are limited. In the face of increasing demand for bandwidth, the traditional commercial communication mainly uses 300MHz to 3GHz. The spectrum resources are extremely tight and cannot meet the needs of future wireless communications.

In future wireless communications, communication will be carried out using carrier frequencies higher than those used in fourth-generation (4G) communication systems, such as 28 GHz, 45 GHz, 70 GHz, etc., which have free propagation losses. Large, easily absorbed by oxygen, and affected by rain attenuation, seriously affecting the coverage of high-frequency communication systems. However, since the carrier frequency corresponding to the high-frequency communication has a shorter wavelength, it is possible to ensure that more antenna elements can be accommodated per unit area, and more antenna elements mean that beamforming can be used to improve the antenna gain. Thereby ensuring the coverage performance of high frequency communication.

After the beamforming method, the transmitting end can concentrate the transmitting energy in a certain direction, and the energy is small or absent in other directions, that is, each beam has its own directivity, and each beam can only cover To a terminal in a certain direction, the transmitting end, that is, the TRP (Transmission Reception Point) needs to transmit beams in dozens or even hundreds of directions to complete the full coverage. In the prior art, the measurement and identification of the preliminary beam direction are performed during the initial access of the terminal to the network, and the preferred uplink and downlink transmission and reception beams are determined and applied in subsequent uplink and downlink data communication.

In the communication network represented by the LTE (Long Term Evolution) system, the mobility discrimination mechanism based on the downlink measurement is adopted, that is, each TRP sends a downlink reference in each downlink port/beam direction according to a predefined configuration. The signal is determined by the terminal based on the measurement of the downlink reference signal to trigger a mobility event, and correspondingly enters a cell reselection or handover process. In a new generation of wireless communication systems, this mechanism will bring huge downlink reference signal transmission overhead in certain deployment scenarios (for example, high site density and relatively small load), and inter-site interference affects the downlink reference signal. Measuring performance. Therefore, it is proposed to apply a mobility discriminating mechanism based on uplink reference signal measurement in such a scenario, that is, the terminal sends an uplink reference signal according to the configuration of the TRP, and the TRP determines whether the mobility event is triggered according to the measurement, and feeds the result back to the terminal. However, this upstream mobility mechanism will have an impact on the paging process of the existing systems described below.

The paging mechanism of the existing LTE system: the terminal accessing the network enters the idle (IDLE) state when no service needs to be transmitted, and the UE in the IDLE state needs to monitor the paging to detect whether there is any target for the UE on the core network side. Call information field (downstream data arrival indication, system message change, receiving EWTS (Earthquake and Tsunami Warning System), receiving CMAS (Commercial Mobile Alert Service). Since the network side cannot know the exact location of the UE in the IDLE state, the paging message will be sent in the tracking area. To ensure reliable reception of the specified UE. On the other hand, for energy saving reasons, the IDLE state UE uses the discontinuous reception (DRX) mechanism and only "wakes up" at a specific moment. This particular moment is called Paging Occasion (PO). The terminal determines, according to the DRX cycle, the specific subframe position in the specific radio frame calculated by the terminal identifier, and the terminal de-control channel acquires whether there is paging information on the current network side, and further determines whether the network side needs to be on the data channel according to the paging scheduling information. Paging yourself, and what is the reason for the paging, and performing the corresponding subsequent operations based on the paging cause.

Under the mobility discriminating mechanism based on the uplink reference signal measurement, the terminal does not listen to the paging information transmitted at the specific paging opportunity position according to a certain period. How to quickly and effectively implement the paging transmission of the network side to the terminal is necessary The problem to be considered, and in the paging transmission process, it is necessary to consider how to facilitate the transmission of subsequent potential downlink data and system information as much as possible.

detailed description

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

For the sake of clarity, first explain some terms:

In the embodiment of the present invention, two types of communication devices are involved:

Network side: Contains one or more communication sites, wherein the configuration information is the same communication site or a different communication site as the sending site of the feedback information. The communication site may be a macro-side base station, a relay node, a network-side device such as a transmitting and receiving node TRP, and is used for sending a paging in the embodiment of the present invention.

The communication node may be a terminal device or a relay node, and is used to receive a page sent by the network side device in the embodiment of the present invention.

In the specific scenario in the embodiment of the present invention, the network side is a transmitting and receiving node (Transmission Reception Point (TRP), and the communication node is a user equipment (UE) as an example to describe the technical solution, and does not indicate specific Limited.

Port: A specific "port" can be used to represent a directional characteristic transmission formed by a specific digital and/or analog beamforming technique, including a transmit port, and a receive port, also referred to as a "transmit beam." And "receive beam". The following is a unified description of "beam" as an example.

Different ports implement coverage of different physical directions, and reference signals transmitted by different ports are used for the receiving end to identify the preferred transmitting port information of the transmitting end; possibly, the receiving end may pass the port number (port index), and/or reference signal resources The index is configured to indicate the preferred transmit port to the transmitting end.

Optionally, the preferred port information fed back by the receiving end may also be a list, that is, including multiple preferred transmitting port information, and the transmitting end determines the finally adopted transmitting port. Correspondingly, the receiving end can also adopt beamforming technology to form different receiving ports. While identifying the preferred transmitting port, the receiving end also determines the preferred receiving port. In subsequent data communications, the transmitting and receiving ends are preferably paired with the transmitting and receiving ports. Complete the data transfer.

Reciprocity: When the uplink and downlink experiences the same wireless channel, such as fast and slow fading, interference, etc., when the channel condition in a certain direction is known, the channel condition in the opposite direction can be obtained without re-estimation. This property is called channel reciprocity, or channel symmetry.

In addition, whether the reciprocity of the communication node is established is also related to whether the communication node has undergone transmission and reception beam calibration before leaving the factory. Specifically, in the preferred port identification method of the embodiment of the present invention, when reciprocity is established, that is, reciprocity is available, and for the terminal or the base station, according to any one of the transceiver ports, another corresponding port can be obtained. This saves the overhead of port identification.

Status information, saving signaling overhead and delay of subsequent paging transmission.

The method of the embodiment of the present invention will be described in detail below in several specific embodiments.

Embodiment 1:

In this embodiment, when the reciprocity of the UE and the TRP side are not established, the paging information transmission process based on the uplink mobility is as shown in FIG. 4, and the specific description is as follows:

Step 101: The network side TRPx sends configuration information to the communication node UE, where the configuration information includes uplink reference signal transmission configuration information, and receiving configuration information of the feedback information, and an association relationship between the uplink reference signal resource and the feedback resource.

The configuration information is a message that the TRPx sends to the terminal after the terminal completes the initial access and enters the link state. After the subsequent terminals have no data to interact, enter the RRC_idle state, or the RRC_inactive state, the mobility decision mechanism based on the uplink reference signal measurement will be performed. That is, the terminal sends the uplink reference signal according to the configuration information obtained in the link state, and is measured by multiple TRPs in the network side, and determines whether there is a mobility event (such as beam reselection, TRP reselection, cell reselection, etc.). occur.

Step 102: The terminal sends an uplink reference signal.

Step 103: The TRP sends feedback information to the terminal, where the feedback information includes paging indication information.

Due to the uplink reference signal sent by the terminal, the TRP to which the terminal belongs may send feedback information to the terminal after the measurement by the network side. Therefore, the TRP that sends the feedback information may be the same node or the TRPx that provided the configuration information. .

As shown in FIG. 5, the serving node TRPx of the UE is a set of uplink reference signal transmission resources configured by the UE, and the set of uplink reference signal transmission resources is used for uplink of one or more transmitting ports or beams of the communication node. The transmission of the reference signal. On this set of resources, a combination of any one of the uplink transmit beams and any one of the uplink receive beams will be implemented. The number of the uplink reference signal transmission resources is determined according to the number of transmission ports or beams of the communication node (ie, UE) and the number of receiving ports or beams of the communication station (ie, TRP). The figure shows that the terminal switches the transmit beam on each uplink reference signal transmission resource (if 4 transmit beams are included, 4 uplink reference signal transmit resources complete one transmit scan), and the TRP side receives with a certain receive beam. After completing one transmission scan of the terminal, the receiving beam is switched on the next uplink reference signal resource and then continuously receives a transmission scan. By analogy, the combined transmission of all uplink transmit and receive beams is completed. In the configuration shown in the figure, the TRP includes 12 receiving ports or beams. To implement the training of all the transmitting ports or beams of the UE and all receiving ports or beams of the TRP, you need to configure 4*12=48 uplink reference signal transmission resources. . In such a process, the TRP side can identify the preferred uplink receive beam and identify the resources corresponding to the preferred uplink transmit beam on the UE side.

As shown in FIG. 6 , through the beam identification process, the grid corresponding UL RS (uplink reference signal) resource is a resource corresponding to the preferred uplink transceiver beam pair. In the previous configuration information, the TRPx configures any association relationship between the uplink reference signal resources and the feedback resources (including the UL RS resources shown in the grid). Since the reciprocity of the TRP and the UE side are not established, that is, the TRP side preferably transmits a beam, preferably a receiving beam, and the UE side preferably transmits a beam, preferably a receiving beam, and needs independent identification. On a set of feedback resources associated with the uplink reference signal transmission resource, it is required to implement combined transmission between any downlink transmission and reception beams, that is, the transmission corresponding to any one of the TRP downlink transmission beams, the terminal needs to poll all the reception beams for reception. In order to ensure that a preferred downlink transceiver combination is found.

The foregoing feedback information includes paging indication information, that is, a 1-bit resource is occupied, to indicate to the terminal whether the current network side has a paging message belonging to the terminal.

The feedback information further includes: a resource that preferably has an uplink transmit beam identifier of UL Tx 2, a preferred transmit beam indication information of the TRP; preferably, the uplink transmit beam identifier is used to let the terminal know the preferred uplink transmit beam, and the preferred uplink transmit beam may also be used. The corresponding resources are represented. The preferred transmit beam indication information of the TRP is sent by the terminal to the TRP, and the resource of the preferred transmit beam indication information of the TRP is used to indicate to the terminal the resource location for sending the indication information.

The terminal identifies the preferred transmit beam on the TRP side through the process of receiving the feedback information by the above scanning, and also obtains To its preferred receive beam, a preferred uplink transmit beam is also obtained from the feedback information.

Step 104: The terminal sends the preferred downlink transmit beam indication information of the TRP to the TRP on the resource indicated by the feedback information by using the preferred uplink transmit beam.

Step 105: After receiving the preferred downlink transmit beam indication of the TRP, the TRP may further send the paging information to the terminal by using the preferred transmit beam.

The preferred transmit beam comprises the following four types:

Two terminal sides: preferably an uplink transmit beam (ie, a preferred beam when the terminal transmits uplink information), preferably a downlink receive beam (ie, a preferred beam when the terminal receives downlink information).

Two base stations: preferably a downlink transmit beam (ie, a preferred beam when the base station transmits downlink information), preferably an uplink receive beam (ie, a preferred beam when the base station receives uplink information).

When the reciprocity of a certain side is established, the preferred beam of the side is known, and another one can be obtained. For example, there is reciprocity on the terminal side. If it already knows the preferred downlink receiving beam, then according to reciprocity, It can get the preferred uplink transmit beam without the need for peer feedback.

The paging information includes paging downlink control information (paging DCI), and paging messages. The paging DCI can be loaded on the physical downlink control channel and scrambled by P-RNTI (Paging-Radio Network Tempory Identity). After the terminal blindly detects the paging DCI, the paging DCI can be further based on the paging DCI. The scheduling information of the indicated paging message, decoding the paging message, obtaining the paging cause, and performing the corresponding action. For example, if the paging cause is system information change, the UE re-receives the system information; if the paging reason is that the downlink data arrives, the terminal accesses the network and receives the downlink data.

Embodiment 2:

In this embodiment, the reciprocity of the UE is not established. When the reciprocity of the TRP is established, the paging information transmission process based on the uplink mobility is as shown in FIG. 7, and the specific description is as follows:

Step 201: The network side TRPx sends configuration information to the communication node UE. The configuration information includes uplink reference signal transmission configuration information, and receiving configuration information of the feedback information, and an association relationship between the uplink reference signal resource and the feedback resource.

Step 202: The terminal sends an uplink reference signal according to the configuration information.

Step 203: The TRP sends feedback information to the terminal by using a preferred downlink transmit beam, where the feedback information includes paging indication information, and preferred uplink transmit beam information of the terminal.

Step 204: The TRP sends downlink data to the terminal by using a preferred downlink transmit beam.

The configuration of the uplink reference signal transmission is the same as that of the first embodiment, and details are not described herein again. In such a process, the TRP side can identify the preferred uplink receive beam and identify the resources corresponding to the preferred uplink transmit beam on the UE side.

As shown in FIG. 8 , through the beam identification process, the grid corresponding UL RS resource is a resource corresponding to the preferred uplink transceiver beam pair. In the previous configuration information, the TRPx configures any association relationship between the uplink reference signal resources and the feedback resources (including the UL RS resources shown in the grid). Since the reciprocity of the TRP is established, the reciprocity of the UE side is not established. That is, the preferred transmit beam on the TRP side can be obtained from the preferred receive beam obtained in the process of receiving the UL RS in the previous stage, and the preferred receive beam on the UE side needs to be independently identified. Associated with this upstream reference signal transmission resource On a set of feedback resources, only the TRP is required to transmit in a preferred downlink transmit beam, and a combined transmission between any downlink receive beams is implemented, that is, corresponding to the transmission of the TRP preferred downlink transmit beam, the terminal needs to poll all receive beams for reception, thereby It is guaranteed to find a preferred downlink receive beam.

The above feedback information includes paging indication information in two ways:

Manner 1: The 1 bit resource is occupied to indicate to the terminal whether the current network side has paging information belonging to the terminal.

Manner 2: occupying x bit resources and directly indicating the reason of the current network side paging terminal to the terminal. For example, 2 bit information: 00 means no paging information, 01 means downlink data arrival, 10 means system information update, and 11 means early warning information arrives. .

In the first mode, if there is paging information, the method of the first embodiment is used to complete the reception of the paging information; in the second mode, the paging reason is assumed to be the arrival of the downlink data.

In the embodiment, the feedback information carries the uplink timing advance (TA) adjustment amount and the preferred uplink transmit beam of the terminal. Therefore, the terminal can implement uplink synchronization, and the terminal does not need to perform the access process again. The terminal blindly checks whether there is its own downlink data scheduling information at each downlink control channel, and receives the specified downlink data. When uplink data transmission or feedback is required, the uplink timing is adjusted according to the TA adjustment amount, and the uplink information is transmitted in a preferred uplink transmit beam.

Embodiment 3:

In this embodiment, when the reciprocity of the UE is established and the reciprocity of the TRP is not established, the paging information transmission process based on the uplink mobility is as shown in FIG. 9 , and the specific description is as follows:

Step 301: The network side TRPx sends configuration information to the communication node UE. The configuration information includes uplink reference signal transmission configuration information, and receiving configuration information of the feedback information, and an association relationship between the uplink reference signal resource and the feedback resource.

Step 302: The terminal sends an uplink reference signal according to the configuration information.

The configuration of the uplink reference signal transmission is the same as that of the first embodiment, and details are not described herein again. In such a process, the TRPx side can identify the preferred uplink receive beam and identify the resources corresponding to the preferred uplink transmit beam on the UE side.

Step 303: The TRP sends feedback information to the terminal, where the feedback information includes paging information.

As shown in FIG. 10, through the beam identification process, the grid corresponding UL RS resource is a resource corresponding to the preferred uplink transceiver beam pair. In the previous configuration information, the TRPx configures any association relationship between the uplink reference signal resources and the feedback resources (including the UL RS resources shown in the grid). Since the reciprocity of the TRP side is not established, the preferred transmit beam on the TRP side needs to be independently identified. The UE side reciprocity is established. On the feedback resource corresponding to the same uplink reference signal resource, the terminal receives the feedback information by using a corresponding receiving beam of the uplink reference signal. On a set of feedback resources associated with the uplink reference signal transmission resource, it is required to implement a polling transmission of all downlink transmission beams of the TRP, that is, the transmission corresponding to any one of the TRP downlink transmission beams, and the terminals receive the same receiving beam. (The receive beam corresponds to the transmit beam of the uplink reference signal) to ensure that a preferred downlink transmit beam is found.

The foregoing feedback information includes paging information, occupies x bit resources, and directly indicates to the terminal the reason of the current network side paging terminal. For example, 2 bit information: 00 represents no paging information, 01 represents downlink data arrival, and 10 represents system information update. , 11 represents the arrival of early warning information.

In the second mode, the paging cause is assumed to be 10: system information update.

Step 304: The terminal performs corresponding system information reception according to the paging reason. Since the base station still does not know the preferred downlink The beam information is transmitted, so the system information will also be sent in a scanning manner, that is, all downlink transmitting beams repeatedly transmit the system information.

Note: In this embodiment, since the paging information is updated by the system information, the terminal does not need to access the network. Therefore, it is not necessary to provide the uplink timing advance TA adjustment amount information for the terminal.

Embodiment 4:

In this embodiment, when the reciprocity of the UE is established and the reciprocity of the TRP is not established, the paging information transmission process based on the uplink mobility is as shown in FIG. 11 , and the specific description is as follows:

Step 401: The network side TRPx sends configuration information to the communication node UE. The configuration information includes uplink reference signal transmission configuration information, and receiving configuration information of the feedback information, and an association relationship between the uplink reference signal resource and the feedback resource.

Step 402: The terminal sends an uplink reference signal according to the configuration information.

Step 403: The TRP sends feedback information to the terminal, where the feedback information includes paging information.

Possibly, as shown in FIG. 12, through the beam identification process, the grid corresponding UL RS resource is a resource corresponding to the preferred uplink transceiver beam pair. In the previous configuration information, the TRPx configures any association relationship between the uplink reference signal resources and the feedback resources (including the UL RS resources shown in the grid). Since the reciprocity of the TRP side is not established, the preferred transmit beam on the TRP side needs to be independently identified. The UE side reciprocity is established. On the feedback resource corresponding to the same uplink reference signal resource, the terminal receives the feedback information by using a corresponding receiving beam of the uplink reference signal. On a set of feedback resources associated with the uplink reference signal transmission resource, it is required to implement a polling transmission of all downlink transmission beams of the TRP, that is, the transmission corresponding to any one of the TRP downlink transmission beams, and the terminals receive the same receiving beam. (The receive beam corresponds to the transmit beam of the uplink reference signal) to ensure that a preferred downlink transmit beam is found.

The feedback information also includes resource information of the terminal transmitting the preferred downlink transmit beam indication information.

Step 404: The terminal feeds back the preferred downlink transmit beam indication information to the TRP with the preferred uplink transmit beam on the resource indicated in the foregoing information. This information can reduce the overhead of the TRP sending system information, that is, it only needs to transmit to the terminal with the preferred downlink transmit beam.

This information has another function. By properly configuring the resources of the downlink transmit beam indication information, it is possible to reduce the overhead of the base station scanning and transmitting the feedback information. As shown in FIG. 13 , one or more transmit resources of the preferred downlink transmit beam indication information are configured between multiple feedback resources, so that if the terminal has successfully received the previous feedback information, the feedback may be timely, so that the TRP can save back feedback. The transmission of information saves signaling overhead.

Step 405: The terminal performs corresponding system information reception according to the paging reason.

Embodiment 5:

In this embodiment, when the reciprocity of the UE side and the TRP side are both established, the paging information transmission process based on the uplink mobility is as shown in FIG. 14 , and the specific description is as follows:

Step 501: The network side TRPx sends configuration information to the communication node UE. The configuration information includes uplink reference signal transmission configuration information, and receiving configuration information of the feedback information, and an association relationship between the uplink reference signal resource and the feedback resource.

Step 502: The terminal sends an uplink reference signal according to the configuration information.

Step 503: The TRP sends feedback information to the terminal by using a preferred downlink transmit beam, where the feedback information includes paging information.

Because the TRP side reciprocity is established, the TRP can obtain the preferred receive beam through the reception of the UL RS, and further obtain the preferred transmit beam. The feedback information does not need to be scanned and sent, and the paging DCI or the paging DCI+paging message can be sent in the feedback information. Moreover, since the reciprocity of the UE side is established, the feedback information does not need to include the preferred transmit beam information of the UE.

As shown in FIG. 15 , through the beam identification process, the grid corresponding UL RS resource is a resource corresponding to the preferred uplink transceiver beam pair. In the previous configuration information, the TRPx configures any association relationship between the uplink reference signal resources and the feedback resources (including the UL RS resources shown in the grid). Since both the TRP and the UE side reciprocity are established, the preferred uplink transmit beam and the preferred uplink receive beam have been identified by the scan transmission and reception of the uplink reference signal. According to the reciprocity, the preferred downlink transmit beam is known on the TRP side, so that no polling is required in the transmission of the feedback information, and only the TRP is required to optimize the downlink transmit beam on the feedback resource corresponding to the uplink reference signal resource. Send feedback. The terminal receives, according to the configuration information, a receive beam corresponding to a beam that transmits an uplink reference signal on the feedback resource. And the terminal can obtain a preferred uplink transmit beam on the terminal side and a preferred downlink receive beam according to the resource that receives the feedback information.

Step 504: The terminal performs corresponding system information reception according to the paging reason.
