Description

Transmission method, apparatus, device, and readable storage medium

CROSS-REFERENCE TO RELATED APPLICATIONS

The present disclosure is based on a Chinese patent application with an application number of 202110029281.3 and an application date of January 11, 2021, and claims the priority of the Chinese patent application, the entire contents of which are hereby incorporated by reference into the present application.

technical field

The present disclosure relates to the field of communication technologies, and in particular, to a transmission method, apparatus, device, and readable storage medium.

Background technique

The 5th generation (5th generation, 5G) high-frequency millimeter wave uses beams for transmission and reception, and introduces the concept of beam correlation (beam correlation), that is, millimeter wave terminals can determine the direction of the transmission beam or the transmission beam through the receiving beam. general direction.

For example, during random access, the terminal determines the downlink beam direction by measuring the downlink reference signal, and uses the uplink beam direction corresponding to the downlink beam to initiate random access to ensure the signal quality and access success rate of uplink access.

Due to the limited coverage of millimeter waves, the use of power amplifiers to amplify signals is an effective way to improve coverage of millimeter waves. As shown in Figure 1a, the terminal is under the coverage of the amplifier. According to the prior art, after the terminal measures the downlink beam, the terminal transmits the uplink signal (for example, random access) by using the uplink beam direction corresponding to the downlink beam.

However, for the scenario where the uplink and downlink work on different frequencies, if the amplifier only supports the downlink signal or the uplink signal amplification, problems will arise. Examples of scenarios are as follows:

1. The downlink of the base station adopts millimeter wave 28GHz, and the uplink adopts the frequency below 6GHz to supplement the uplink coverage, and the amplifier only supports the 28GHz millimeter wave frequency band;

2. The base station adopts Supplementary Uplink (SUL) technology and works in the 28GHz Time Division Duplexing (TDD) frequency band + the SUL frequency band below 6GHz, and the amplifier only supports the 28GHz millimeter wave frequency band;

3. The base station uses the 28GHz millimeter-wave frequency band for the uplink, and the downlink uses the frequency below 6GHz. The amplifier only supports the 28GHz millimeter-wave frequency band.

In the above three scenarios, since the repeater cannot support the simultaneous amplification of uplink and downlink signals at the same time, the terminal under the coverage of the amplifier will not be able to use the beam correspondence feature to judge the transmission direction of the uplink beam by the direction of the downlink beam (as shown in Figure 1b and Figure 1). 1c). According to the prior art, the terminal will fail to transmit uplink.

Step 201: Receive the first information and/or the second information sent by the network side;

Step 202: Perform transmission according to the first information and/or the second information; wherein the first information indicates that the beam correlation is turned off or turned on, and the second information indicates that the repeater (repeater) supports frequency band or frequency.

In this embodiment of the present disclosure, the first information further indicates the next item or items:

(1) Whether the uplink and downlink beams of the terminal are mutually exclusive, that is, whether the terminal can determine the uplink transmit beam according to the downlink receive beam;

(2) Whether each uplink carrier of the terminal is turned off or turned on beam correspondence;

(3) Turn off the carrier of beam correspondence;

(4) whether the terminal uses the downlink receive beam to judge or determine the information of the uplink transmit beam;

(5) Whether the terminal needs to perform uplink beam scanning.

In this embodiment of the present disclosure, the second information further instructs the terminal to receive and/or transmit through a repeater or directly through a network-side device.

In this embodiment of the present disclosure, when the first information includes: disable beam correlation, or the frequency band or frequency supported by the repeater indicated by the second information is different from the frequency sent by the terminal in uplink, the method It also includes: turning off the beam correspondence of the terminal, or the terminal cannot judge or determine the uplink transmission beam through the downlink receiving beam, or whether the terminal needs to perform uplink beam scanning.

That is, the terminal cannot use the downlink receive beam to determine the uplink transmit beam, and needs to transmit the uplink in a trial-by-try manner, that is, uplink beam scanning. Since the terminal does not have the beam correspondence capability, the network-side device cannot receive the uplink beam according to the direction of the downlink transmit beam, and the network-side device also needs to perform beam scanning on the receive beam.

In this embodiment of the present disclosure, the transmitting according to the first information and/or the second information includes: turning off beam correspondence at the terminal, and sending a first message (such as message 1 (MSG1) at the terminal) If no response message (such as message 2 (MSG2)) is received after ), an uplink beam scan is performed, and the terminal attempts to send the first message on other beams.

In this embodiment of the present disclosure, the communication relationship between the terminal and the repeater indicates whether the terminal is within the coverage of the repeater, or whether the received and/or sent signals are amplified or forwarded by the repeater, or whether the terminal is connected or received through the repeater. enter.

In the embodiment of the present disclosure, the communication relationship between the uplink carrier or frequency and the target power includes one or more of the following: different uplink carriers or frequencies correspond to different target powers; whether the signal of the same uplink carrier or frequency passes through the repeater Amplify or forward, corresponding to different target powers.

P _PRACH,b,fc (i)=min{P _CMAX,f,c (i), _{PRACH,target,f,c} +PL _b,f,c }[dBm]

_CMAX,f,c (i) is the maximum transmit power configured by the terminal. Assuming that terminal 1 and terminal 2 are terminals of the same power level, the configured maximum transmit power of terminal 1 and terminal 2 is the same.

P _{PRACH,target,f,c} is the target power received by the network side.

PL _{b, f, and c} are path loss (transmit power of downlink reference signal - reference signal received power (Reference Signal Received Power, RSRP)), terminal 1 is at the partial edge of the cell coverage, and terminal 2 is under the coverage of the repeater, so The path loss calculated by terminal 1 is relatively large, and the path loss calculated by terminal 2 is relatively small. However, the actual terminal 2 is farther from the base station, and in the prior art, each uplink carrier transmits a target received power.

P _PRACH,b,fc (i) is the power for transmitting a physical random access channel (Physical Random Access Channel, PRACH). Through calculation, the transmit power of the terminal 2 is low, resulting in a failure of uplink transmission.

Therefore, for scenarios with repeaters, different target powers need to be sent on the same uplink carrier or frequency, that is, whether there are repeaters to send different target powers, that is:

(1) The terminal 1 uses the target power 1 sent by the network side to calculate the transmit power;

(2) The terminal 2 uses the target power 2 sent by the network side to calculate the transmit power.

target power 1: preambleReceivedTargetPower;

Target Power 2: preambleReceivedTargetPower-repeater.

By setting different target transmit powers, the network side can compensate for the problem that the downlink RSRP cannot be used to estimate the path loss due to the presence of repeaters, thereby avoiding the terminal's uplink transmission failure.

In this embodiment of the present disclosure, the transmitting according to the first information and/or the second information includes:

According to the first information, select an uplink carrier or frequency that does not instruct to turn off beam correspondence or instruct to turn on beam correspondence to send uplink; and/or, according to the second information, select an uplink carrier or frequency supported by the repeater to send uplink.

Step 401: Receive third information sent by a second network side device;

It can be understood that the first network side device may be the base station of the source cell, and the second network side device may be the base station of the target cell.
