Description

Technical Field

The application belongs to the technical field of communication, and particularly relates to an information acquisition method, an information transmission device, a terminal and network side equipment.

Background

Timing Advance (TA) is used for terminal uplink transmission in order to ensure that the terminal uplink data packet arrives at the base station within a desired time. In the cell switching scenario at present, generally, after a terminal successfully receives a high-level command indicating cell switching and completes downlink synchronization and AGC adjustment, a preamble is sent to a target cell, and the target cell acquires a TA value by feeding back the TA value to the terminal. The terminal interrupts the data transmission with the source cell after receiving the high-level signaling indicating the cell switching, and the high-level signaling has longer processing time and a certain time overhead in downlink synchronization, so the interrupt time of the terminal and the current service cell is longer.

The information acquisition method, the information acquisition device, the information transmission method, the information transmission device, the terminal and the network side device provided by the embodiment of the application are described in detail below through some embodiments and application scenes thereof with reference to the accompanying drawings.

Fig. 2 shows a flowchart of an information acquisition method according to an embodiment of the present application. As shown in fig. 2, the information acquisition method includes the steps of:

step 201: the terminal receives a target signaling sent by network side equipment;

step 202: the terminal obtains a Timing Advance (TA) value of the terminal under a first object according to the target signaling; wherein the target signaling is signaling acquired before the terminal accesses the first object.

The target signaling is acquired before the terminal accesses the first object, which is understood to mean that the terminal has acquired the target signaling before the terminal accesses the first object, which is understood to mean that the terminal switches from the current service object to the first object. The first object may be a group of cells, a cell, or a transmitting and receiving point (Transmission and Reception Point, TRP).

In some embodiments, the target signaling includes at least one of:

Second signaling for indicating information of the first object;

and third signaling, wherein the third signaling is used for acquiring the TA value of the first object.

Further, the first signaling, the second signaling, and the third signaling satisfy either of the following two cases:

the first signaling and the second signaling are different signaling, and the second signaling and the third signaling are the same signaling;

the first signaling, the second signaling, and the third signaling are different signaling.

The first signaling is described in relation to:

the first signaling may be radio resource control (Radio Resource Control, RRC) signaling. The first signaling may contain configuration information for a plurality of objects, which may include at least one of:

configuration information of a second object, wherein the second object is an object which provides service for the terminal currently, namely a current service object such as a service cell;

configuration information of at least one candidate object, the at least one candidate object comprising the first object;

a reference timing difference of each candidate object with the second object;

uplink synchronization indication information of each candidate object;

Downlink synchronization indication information of each candidate object.

The configuration information of the at least one candidate may include all configuration information of each candidate configured in units of one candidate or include partial configuration information of each candidate configured in units of one candidate. In the latter case, the remaining configuration information of each candidate object may be the same as the configuration information of the second object. The configuration information of the candidate object may include at least one of higher layer configuration information including at least one of cell group configuration information CellGroupConfig, primary cell configuration information SpCellConfig, reconfiguration information carrying synchronization ReconfigurationWithSync, common configuration information ServingCellConfigCommon of the serving cell, serving cell configuration information ServingCellConfig, and physical layer related configuration information including at least one of transmission configuration indication (Transmission Configuration Indicator, TCI), quasi co-location (QCL), PL RS, random access channel (Random Access Channel, RACH) resources, scrambling code information, frequency domain information (e.g., synchronization signal block (Synchronization Signal and PBCH block, SSB) frequency point, CSI reference signal (CSI Reference Signal, CSI-RS) frequency point and frequency band indication), subcarrier spacing (subcarrier spacing, SCS), channel sounding reference signal (Sounding Reference Signal, SRS).

The reference timing difference of each candidate object and the second object may be configured as follows: first, configuring a reference timing difference and a parameter value that is not zero or greater than a first threshold, such configuration may indicate that a candidate object is unsynchronized with the second object; second, the default reference timing difference, or the reference timing difference is configured with a parameter value of zero or less than a first threshold, which configuration may indicate that the candidate object is synchronized with the second object. Here, the first threshold may be configured by the network side device or agreed upon by a protocol or determined according to terminal capabilities. The accuracy of the reference timing difference of the candidate object and the second object may be at least one of a frame, a slot, an orthogonal frequency division multiplexing (Orthogonal frequency division multiplex, OFDM) symbol, a second, a millisecond, a microsecond, a nanosecond. The reference timing difference of the candidate object and the second object may be configured in configuration information of the candidate object.

The uplink synchronization indication information of each candidate object may indicate a timing advance group (Timing Advance Group, TAG) identification corresponding to the candidate object, or indicate whether the candidate object and the first object belong to different TAGs. The uplink synchronization indication information of each candidate object may be 1-bit indication information, where 0 represents uplink synchronization and 1 represents non-uplink synchronization, or the uplink synchronization indication information of each candidate object is Bool type information, where true represents uplink synchronization and false represents non-uplink synchronization. Alternatively, if the uplink synchronization instruction information is configured, the uplink synchronization instruction information indicates non-uplink synchronization, and if the parameter is default, the uplink synchronization instruction information may be default. The uplink synchronization indication information of the candidate object may be configured in configuration information of the candidate object.

The second signaling is described in relation to:

the second signaling may include one of MAC CE and downlink control information (Downlink Control Information, DCI), wherein the DCI may include at least one of downlink DCI (DL DCI) and uplink DCI (UL DCI). The second signaling indicates the first object in at least two ways: first, the second signaling includes a target field for indicating the first object, that is, the second signaling has a field for indicating the first object; second, the second signaling includes beam indication information, where the beam indication information is associated with the first object, that is, the beam indication information carried in the second signaling is associated with the first object, and the beam indication information may include a transmission configuration indication (Transmission Configuration Indicator, TCI) state (i.e., TCI state), a joint TCI (Joint TCI), a DL TCI, a UL TCI, or a Spatial relationship (Spatial relationship). The terminal may determine the first object from the candidate objects included in the first signaling according to the second signaling, and the identification indication of the first object may be the same as or different from the identification indication of the second object.

For the case where the second signaling is the same signaling as the third signaling, the above description of the second signaling applies to the third signaling. In this case, the terminal may obtain the TA value of the terminal under the first object according to the RACH resource associated with the Reference Signal (RS) corresponding to the beam indication information carried in the second signaling.

For the case where the second signaling is the same signaling as the third signaling, the second signaling may also carry a TA value. In this way, the terminal can determine the TA value carried in the second signaling as the TA value of the terminal under the first object.

For the case that the second signaling and the third signaling are different signaling, the following description will be given on the third signaling:

the third signaling is used to activate at least one RACH resource of at least one object, the activated RACH resource being used to obtain a TA value of the at least one object.

The third signaling may include at least one of:

first indication information for indicating one or more Preamble index (Preamble index);

second indication information for indicating one or more reference signal RS indexes;

third indication information for indicating a preamble signal mask index (Preamble Mask index);

fourth indication information for indicating an identification of the at least one object;

fifth indicating information for indicating a configuration information index of the at least one object;

a sixth indication information for indicating frequency domain indication information of the at least one object;

Wherein the at least one object comprises the first object.

As an example, the third signaling activatable RACH resource may be a contention-based random access (Contention Based Random Access, CBRA) or a non-contention random access (Contention Free Random Access, CFRA), which may be indicated as CBRA when Preamble index is 0, and which may be indicated as CFRA when Preamble index is not 0.

In the embodiment of the application, for the related scheme that the terminal obtains the TA value of the terminal under the first object according to the target signaling, the terminal may obtain the TA value of the terminal under the first object according to the first signaling and the second signaling, the terminal may obtain the TA value of the terminal under the first object according to the third signaling, the terminal may obtain the TA value of the terminal under the first object according to the SRS sent by the target signaling, and the TA value is obtained by the network side device, or the terminal may obtain the TA value of the terminal under the first object by sending the preamble signal according to the target signaling and sending the TA value by the network side device. These alternative embodiments are described below:

As an implementation manner, the obtaining, by the terminal, the TA value of the terminal under the first object according to the target signaling includes:

the terminal determines a reference timing difference between the first object and the second object and a downlink receiving time difference between the first object and the second object according to the first signaling and the second signaling;

and the terminal determines the TA value of the terminal under the first object according to the TA value of the second object, the reference timing difference between the first object and the second object and the downlink receiving time difference between the first object and the second object.

This embodiment is particularly applicable in case the first object is not synchronized with the second object. In this case, there is a reference timing difference and a downlink receiving time difference between the first object and the second object, and the terminal may determine the TA value of the terminal under the first object according to three parameters, that is, the TA value of the second object, the reference timing difference between the first object and the second object, and the downlink receiving time difference between the first object and the second object.

It should be noted that, since the second object is the current service object, the TA value of the second object is already acquired in advance by the terminal.

As described above, the first signaling is used to indicate configuration information of the plurality of objects, and as an example, the reference timing difference between the first object and the second object and/or the downlink reception time difference between the first object and the second object may be included in the configuration information of the plurality of objects indicated by the first signaling.

In this embodiment, the terminal determines the TA value of the terminal under the first object according to the two signaling, i.e. the first signaling and the second signaling.

and the terminal obtains the TA value of the terminal under the first object according to the first signaling and the second signaling, wherein the TA value of the terminal under the first object is the same as the TA value of the terminal under the second object.

Here, the TA of the second object may be informed to the terminal by the network-side device through a legacy random access response (Random Access Response, RAR) or MAC CE. As an example, the uplink synchronization indication information and the downlink synchronization indication information included in the first signaling are used to indicate whether the TA value of each candidate cell is the same as the TA value of the second object, and the second signaling is used to determine the first object, so the terminal may determine whether the TA value of the first object is the same as the TA value of the second object according to the first signaling and the second signaling. This embodiment is particularly applicable to the case where the TA value of the first object is the same as the TA value of the second object, i.e. the case where the first object and the second object are synchronized. In this case, the TA value of the terminal under the first object is the same as the TA value of the terminal under the second object, and the terminal may use the TA value under the second object as the TA value under the first object.

Wherein the association relationship between the first TA group and the at least one object is configured explicitly or implicitly by the network, and the at least one object includes the first object. The terminal can acquire the TA value of the terminal under the first object from the information carried by the second signaling. Specifically, the TA group identifier may be indicated by O bits, where the value of O is K is the maximum number of TA groups that the terminal can maintain under the first object, or the maximum number of TA groups that the terminal can maintain under the at least one object.

In this embodiment, the SRS may be determined by the terminal according to the configuration information in the first signaling, or in case the target signaling further includes the third signaling, the SRS is activated by the third signaling.

Optionally, the beam indication information of the SRS is associated with the identification of the at least one object, and the SRS is sent based on timing information of a second object, where the second object is an object that currently provides service to the terminal. Here, the identification of the beam indication information of the SRS in association with the at least one object may be understood as the identification of the spatial relationship of the SRS in association with the at least one object. As an example, the beam indication information of the SRS is associated with the identification of the first object.

In this embodiment, the time for the terminal to transmit the SRS is after receiving the first signaling or the third signaling, and the time for the terminal to receive the second signaling is after SRS transmission, and in this case, the second signaling is not included in the target signaling.
