Description

Transmission method, device, terminal and network side equipment

Technical Field

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

Background

Analog beamforming is full bandwidth transmit and each polar array element on the panel of each high frequency antenna array can only transmit analog beams in a time division multiplexed manner. The shaping weight of the analog beam is realized by adjusting parameters of equipment such as a radio frequency front end phase shifter and the like.

At present, a polling method is usually used to train an analog beamforming vector, that is, an array element in each polarization direction of each antenna panel sequentially sends a training signal (i.e., a candidate beamforming vector) at an appointed time in a time division multiplexing manner, and a terminal feeds back a beam report after measurement, so that a network side uses the training signal to implement analog beamforming transmission when transmitting a service next time. The contents of the beam report typically include the optimal number of transmit beam identifications and the measured received power of each transmit beam.

When performing beam measurement, the network configures a Reference Signal Resource Set (Reference Signal Resource Set), which includes at least one Reference Signal Resource, such as a Synchronization Signal Block (SSB) Resource or a Channel State Information Reference Signal (CSI-RS) Resource. The terminal measures the Layer 1Reference Signal Received Power (L1-RSRP) or the Layer 1Signal to Interference plus Noise Ratio (L1-SINR) of each Reference Signal Resource, and reports at least one optimal measurement result to the network, wherein the report content comprises SSB Resource Indicator (SSB Resource Indicator, SSBRI) or CSI-RS Resource Indicator (CRI), L1-RSRP or L1-SINR. The report content reflects at least one optimal beam and its quality for the network to determine the beam used to transmit the channel or signal to the terminal.

In the prior art, when a network indicates beam switching of a downlink or uplink channel or a reference signal, a terminal may measure a first SSB after beam switching signaling, so as to determine parameter information of a time domain and a frequency domain. However, since the SSB has a long period, the measurement delay is increased, and the beam information indicated by the network cannot be matched with the channel condition in real time, which affects the accuracy of beam indication and reduces the system performance.

The transmission method, the apparatus, the terminal and the network side device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 2, an embodiment of the present application provides a transmission method, including:

step 201, a terminal receives a first command, where the first command includes: first beam information; the first beam information is applicable to at least one first channel and/or at least one first reference signal.

The first command may be a Media Access Control layer Control Element (Media Access Control Element) or Downlink Control Information (DCI).

Step 202, determining first information according to a measurement result of the first signal under the condition that a first preset condition is met; the first signal is a synchronization signal block SSB which is the nearest before the first command is received, or a second reference signal;

step 203, transmitting the first channel and/or the first reference signal according to at least one of the first information and the first beam information.

It should be noted that the "beam information" mentioned in the embodiments of the present application may also be referred to as: spatial relationship (spatial relationship) information, spatial domain transmission filter (spatial filter) information, spatial filter (spatial filter) information, transmission configuration indication state (TCI state) information, quasi co-location (QCL) information, QCL parameters, or the like. The downlink beam information may be generally represented by TCI state information or QCL information. The uplink beam information can be generally expressed by spatial relationship information, and is not particularly limited herein.

In an embodiment of the present application, the first information includes at least one of:

time domain information; for example, average delay (average delay), delay spread (delay spread);

frequency domain information; for example, Doppler shift (Doppler shift), Doppler spread (Doppler spread);

beam information; in the case that the first information includes beam information of the second reference signal, the beam information of the second reference signal may be the same as the first beam information or may be different from the first beam information, and is not limited herein.

In this embodiment, the first beam information may be beam information of a certain channel, or beam information of a certain reference signal, or may be beam information of a plurality of channels or reference signals. When the first beam information is beam information of a plurality of channels or reference signals, the first beam information may be referred to as common beam information (i.e., common beam information).

Wherein, in a case that the first beam information is common beam information, the beam information of the second reference signal is the common beam information (i.e. the common beam information can be used by the beam information of the second reference signal).

As an alternative embodiment, in the case that the first signal is the SSB that is the latest before the first command is received, the first preset condition includes:

and the terminal does not receive the SSB within a first preset time after receiving the first command.

In other words, the embodiment does not change the existing signal transmission architecture (i.e., does not increase transmission of a new reference signal), and in order to reduce the delay of beam switching, if the terminal does not receive the SSB within the first preset time period after the first command, the terminal multiplexes the first information measured by the previous SSB. Optionally, the first preset duration is less than or equal to a period length of the SSB.

As another alternative embodiment of the present application, in the case that the first signal is the second reference signal, the first preset condition includes any one of:

the first command further comprises: indication information for activating or triggering the second reference signal;

the terminal receives a second command, wherein the second command comprises indication information used for activating or triggering the second reference signal; for example, the first command is a MAC CE command or DCI signaling, and the second command is RRC signaling or a MAC CE command or DCI signaling.

In this embodiment, when the network instructs the terminal to perform beam switching through the first command, the terminal performs measurement using a reference signal other than the SSB (i.e., the second reference signal) to speed up obtaining the first information, thereby reducing the delay of beam switching.

It should be noted that, the second reference signal mentioned in the embodiment of the present application may be any one of the following:

channel State Information Reference Signal (CSI-RS);

tracking Reference Signal (TRS);

a channel Sounding Reference Signal (SRS);

positioning Reference Signals (PRS);

In an optional embodiment of the present application, if the first preset condition is that the first command includes the indication information, step 202 includes:

and if the terminal does not receive the SSB within a second preset time length after receiving the first command or within a third preset time length after transmitting the acknowledgement feedback information of the first command, measuring the first signal, and determining the first information according to the measurement result of the first signal.

Correspondingly, if the terminal receives the SSB within the second preset time period after receiving the first command or within the third preset time period after transmitting the acknowledgement feedback information of the first command, the SSB is used for measurement, and the terminal may not measure the second reference signal any more or the network may not transmit the second reference signal any more.

Optionally, if the first preset condition is that the first command includes the indication information, the second reference signal may be an aperiodic reference signal, and the first command may activate or trigger a single transmission of the second reference signal.

In yet another optional embodiment of the present application, if the first signal is a second reference signal, the method further comprises:

and if the terminal does not receive the SSB within a fourth preset time length after receiving the first command or within a fifth preset time length after transmitting the acknowledgement feedback information of the first command, the terminal receives the second command.

Correspondingly, if the terminal receives the SSB within a fourth preset time period after receiving the first command or within a fifth preset time period after transmitting the acknowledgement feedback information of the first command, the terminal uses the SSB to perform measurement to obtain the first information, and the terminal may ignore the second command or the network may not transmit the second command any more.

In another optional embodiment of the present application, if the first preset condition is that the terminal receives the second command, step 202 includes:

and if the terminal does not receive the SSB within a sixth preset time after receiving the second command or within a seventh preset time after transmitting the acknowledgement feedback information of the second command, measuring the first signal, and determining the first information according to the measurement result of the first signal.

Correspondingly, if the terminal receives the SSB within the sixth preset time period after receiving the second command or within the seventh preset time period after transmitting the acknowledgement feedback information of the second command, the SSB is used for measurement, and the terminal may not measure the second reference signal any more or the network may not transmit the second reference signal any more.

Optionally, if the second preset condition is that the second command is received, the second reference signal may be a non-periodic reference signal, a periodic reference signal, or a semi-persistent reference signal. If the second reference signal is an aperiodic reference signal, the indication information may activate or trigger a single transmission of the second reference signal; if the second reference signal is a periodic reference signal, the indication information may activate or trigger periodic transmission of the second reference signal (in this case, the indication information may also be referred to as periodic configuration information); the indication information may activate or trigger a semi-persistent transmission of the second reference signal if the second reference signal is a semi-persistent reference signal.

As an optional embodiment of the present application, if the second reference signal is a periodic reference signal or a semi-persistent reference signal, the second command further includes: periodic configuration information of the second reference signal. For example, the period configuration information includes: period information, offset information, etc.

In order to reduce the time delay for acquiring the first information, optionally, the period length of the second reference signal is smaller than the period length of the SSB.

For the periodic or semi-continuous second reference signal, as an alternative embodiment, step 202 includes:

under the condition that a first preset condition is met, measuring a first signal from a first moment, and determining first information according to the measurement result of the first signal;

wherein the first time comprises any one of:

the time corresponding to the eighth preset time after the first command is received;

and transmitting the feedback confirmation information of the first command at a time corresponding to the ninth preset time.

In this case, after the first command, the terminal measures the second reference signal, or measures the second reference signal and the first arriving one of the SSBs, not measuring or ignoring the second arriving one. For example, if the second reference signal arrives first, the terminal measures the second reference signal, and ignores the SSB that arrives later; for another example, if the SSB arrives first, the terminal measures the SSB and ignores the second reference signal that arrives later.

In other words, for the periodic or semi-continuous second reference signal, the embodiments of the present application provide the following two measurement mechanisms:

measuring the second reference signal from the first time instant (whether or not the SSB is received);

and the terminal does not receive the SSB within the preset time length after receiving the first command or within the preset time length after transmitting the feedback confirmation information of the first command, and measures the second reference signal.

As another alternative embodiment of the present application, the method further comprises:

acquiring a preset transmission time interval of a second reference signal, and measuring the second reference signal by a terminal in the preset transmission time interval; correspondingly, the network side device sends the second reference signal within the preset transmission time interval.

Optionally, the terminal and the network side device stop the transmission and reception of the second reference signal outside the preset transmission time interval.

Optionally, the terminal stops receiving the second reference signal outside the preset transmission time interval, but the network side device does not limit the transmission of the second reference signal to the preset transmission time interval.

Wherein the preset transmission time interval is configured by a network, or the preset transmission time interval of the second reference signal is determined by a predetermined convention. If the preset transmission time interval is configured by the network, the network may configure the preset transmission time interval through the second command, or may configure the preset transmission time interval through a new command (e.g., a third command), which is not specifically limited herein.

Wherein the preset transmission time interval includes: the second time to the third time; wherein the content of the first and second substances,

the second time includes: the time corresponding to the tenth preset time after the first command is received, or the time corresponding to the eleventh preset time after the feedback confirmation information of the first command is transmitted; for example, when the first command is MAC CE, the second time is: and the ACK of the MAC CE feeds back the time +3ms later.

The third time includes: the transmission time of the nth SSB after the first command, N being an integer greater than or equal to 1. The value of N may be configured or pre-agreed by the network using higher layer signaling.

As an alternative embodiment, in order to avoid repeating the measurement to improve the efficiency of acquiring the first information, after step 202, the method further includes:

the measurement of the SSB transmitted after the second reference signal is stopped.

In an optional embodiment of the present application, in case that the first signal is a synchronization signal block SSB that is the latest before the first command is received, step 203 comprises:

and after receiving a twelfth preset time length after the first command or after transmitting a thirteenth preset time length after the acknowledgement feedback information of the first command, the terminal uses at least one of the first beam information and the first information when transmitting a first channel and/or a first reference signal.

Further, after a fourteenth preset time period after receiving the first command or a fifteenth preset time period after transmitting the acknowledgement feedback information of the first command, the terminal uses at least one of the first beam information and the first information when transmitting the first channel and/or the first reference signal, including:

It should be noted that, the fourteenth preset time period at least includes at least one of a transmission time of the second reference signal and a processing time of the second reference signal, relative to the twelfth preset time period; the fifteenth preset time period at least includes at least one of a transmission time of the second reference signal and a processing time of the second reference signal relative to the thirteenth preset time period.

Optionally, the terminal does not measure the second reference signal before the fourth time.

Wherein, after the fourth time, the terminal performs measurement of the second reference signal, including:

after the fourth time, the terminal measures the second reference signal using the first beam information.

In other words, if the beam information of the second reference signal is different from the first beam information, the beam information of the second reference signal is rewritten into the first beam information after the fourth time, and then the transmission and measurement of the second reference signal are performed through the first beam information.

It should be noted that, the specific value from the first preset time period to the seventeenth preset time period may be 0, or may be a numerical value greater than 0, and is not limited specifically herein. In general, the first to seventeenth preset time periods include: receiving time of a command corresponding to the preset time length and processing time of the command corresponding to the preset time length; for the case where the TCI state is unknown, additional processing time is required, namely, the time required for Layer 1reference Signal received power (L1-RSRP) or Layer 1Signal to Interference plus Noise Ratio (L1-SINR) measurement and reporting.
