Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of communication, in particular to a transmission method, device, equipment and readable storage medium. BACKGROUND

[0002] The fifth generation mobile communication technology (5th generation, 5G) high frequency millimeter wave adopts beam for transmission and reception, and introduces the concept of beam correspondence, that is, the millimeter wave terminal can determine the transmission beam direction or the approximate direction of the transmission beam through the reception beam.

[0003] For example, when random access, the terminal determines the downlink beam direction by measuring the downlink reference signal, and then 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.

[0004] Due to the limited coverage of millimeter wave, using a power amplifier to amplify the signal is an effective means to improve the coverage of millimeter wave. As shown in Figure 1a , the terminal is under the coverage of the amplifier, according to the prior art, the terminal measures the downlink beam, and then uses the uplink beam direction corresponding to the downlink beam to transmit the uplink signal (such as random access).

[0005] However, for the scenario where uplink and downlink work on different frequencies, if the amplifier only supports the amplification of downlink signals or uplink signals, problems will occur. For example:

[0006] 1. The base station uses millimeter wave 28GHz for downlink, and uses 6GHz or below frequency for uplink to supplement uplink coverage, and the amplifier only supports 28GHz millimeter wave frequency band;

[0007] 2. The base station uses Supplementary Uplink (SUL) technology and works on 28GHz TDD frequency band + 6GHz or below SUL frequency band, and the amplifier only supports 28GHz millimeter wave frequency band;

[0008] 3. The base station uses 28GHz millimeter wave frequency band for uplink, and uses 6GHz or below frequency for downlink, and the amplifier only supports 28GHz millimeter wave frequency band.

[0009] As in the above three scenarios, since the repeater cannot simultaneously support the amplification of uplink and downlink signals, the terminal under the coverage of the amplifier cannot use the beam correspondence feature to determine the uplink beam transmission direction through the downlink beam direction (as shown in Figure 1b and Figure 1c ). If according to the prior art, the terminal uplink transmission will fail. SUMMARY

[0095] Referring to Figure 2 The embodiments of the present application provide a transmission method, executed by a terminal, and the specific steps include steps 201 and 202.

[0096] Step 201: receiving first information and / or second information sent by a network side;

[0097] Step 202: transmitting according to the first information and / or the second information;

[0098] The first information indicates whether to close or open beam correspondence, and the second information indicates a frequency band or frequency supported by a repeater.

[0099] In the embodiments of the present application, the first information further indicates one or more of the following:

[0100] (1) whether the uplink and downlink beams of the terminal have correspondence, i.e., whether the terminal can determine the uplink transmission beam according to the downlink reception beam;

[0101] (2) whether to close or open beam correspondence for each uplink carrier of the terminal;

[0102] (3) the carrier on which beam correspondence is closed;

[0103] (4) whether the terminal uses information for determining the uplink transmission beam according to the downlink reception beam;

[0104] (5) whether the terminal needs to perform uplink beam scanning.

[0105] In the embodiments of the present application, the second information further indicates that the terminal receives and / or transmits through the repeater or directly through the network side device.

[0106] In the embodiments of the present application, if the first information comprises: the beam correspondence is closed, or the frequency band or frequency supported by the repeater indicated by the second information is different from the frequency of the uplink transmission of the terminal, the method further comprises:

[0107] The beam correspondence of the terminal is closed, or the terminal cannot determine the uplink transmission beam through the downlink reception beam, or whether the terminal needs to perform uplink beam sweeping.

[0108] That is, the terminal cannot determine the uplink transmission beam using the downlink reception beam, and needs to transmit the uplink in a way of trying one by one, that is, uplink beam sweeping. Since the terminal does not have the beam correspondence capability, the network side device cannot receive the uplink beam according to the downlink transmission beam direction, and the reception beam of the network side device also needs to perform beam sweeping.

[0109] In the embodiments of the present application, the transmission according to the first information and / or the second information comprises:

[0110] If the terminal closes the beam correspondence, and does not receive a response message (such as message 2 (MSG2)) after the terminal transmits a first message (such as message 1 (MSG1)), uplink beam sweeping is performed, and the terminal tries to transmit the first message on other beams.

[0111] In the embodiments of the present application, the method further comprises:

[0112] Receiving the power information transmitted by the network side, the power information comprising: the target power received by the network side;

[0113] According to one or more of the correspondence between the terminal and the repeater, the correspondence between the uplink carrier or frequency and the target power, the corresponding target power is selected to calculate the uplink transmission power.

[0114] In the embodiments of the present application, the correspondence between the terminal and the repeater indicates whether the terminal is in the coverage range of the repeater, or whether the received and / or transmitted signal is amplified or forwarded through the repeater, or whether it is connected or accessed through the repeater.

[0115] In the embodiments of the present application, 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 signals of the same uplink carrier or frequency are amplified or forwarded by a repeater corresponds to different target powers.

[0116] Referring to Figure 5 , the following describes how to determine the uplink transmission powers of the terminal 1 and the terminal 2.

[0117] P PRACH，b，fc (i) = min{P CMAX，f，c (i), P PRACH，target，f，c + PL b，f，c}[dBm]

[0118] P CMAX，f，c (i) is the maximum transmission power configured by the terminal, and assuming that the terminal 1 and the terminal 2 are terminals of the same power class, the configured maximum transmission powers of the terminal 1 and the terminal 2 are the same.

[0119] P PRACH，target，f，c is the target power received by the network side.

[0120] PL b，f，c is the path loss (transmission power of a downlink reference signal - Reference Signal Received Power RSRP), the terminal 1 is at the edge of the coverage of a cell, and the terminal 2 is under the coverage of a repeater, so the terminal 1 calculates a larger path loss, and the terminal 2 calculates a smaller path loss. However, the terminal 2 is actually farther away from the base station, and in the prior art, one target reception power is sent for each uplink carrier.

[0121] P PRACH，b，fc (i) is the power of sending a physical random access channel (PRACH), and through calculation, the transmission power of the terminal 2 is lower, resulting in uplink transmission failure.

[0122] Therefore, for a scenario in which a repeater exists, different target powers need to be sent for the same uplink carrier or frequency, that is, different target powers are sent according to whether there is a repeater, that is:

[0123] (1) the terminal 1 uses the target power 1 sent by the network side to calculate the transmission power;

[0124] (2) the terminal 2 uses the target power 2 sent by the network side to calculate the transmission power.

[0125] The target power 1 is preambleReceivedTargetPower.

[0126] Target power 2: preambleReceivedTargetPower-repeater.

[0127] By setting different target transmission 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 the repeater, and avoid uplink transmission failure of the terminal.

[0128] In the embodiments of the present application, the transmission according to the first information and / or the second information comprises:

[0129] According to the first information, selecting an uplink carrier or frequency indicated by the terminal to send uplink; and / or, according to the second information, selecting an uplink carrier or frequency supported by the repeater to send uplink.

[0130] In the prior art, the terminal selects an uplink carrier according to the downlink RSRP, so it is possible to select an uplink carrier that is not supported by the repeater and cannot use the beam correspondence capability. At this time, the terminal should select or the network should schedule an uplink carrier or frequency supported by the repeater.

[0131] In the embodiments of the present application, the method further comprises:

[0132] receiving a handover command from the network side device, the handover command indicating one or more of:

[0133] (1) the terminal switches to a cell with a repeater;

[0134] (2) the terminal switches to a beam amplified by the repeater;

[0135] (3) the terminal switches to a frequency band or frequency supported by the repeater in the current cell and initiates random access;

[0136] (4) the terminal switches to a target cell and an uplink random access carrier, and closes the beam correspondence capability.

[0137] In the embodiments of the present application, the problem of uplink transmission failure caused by the conventional method of determining the uplink beam only through the downlink beam is solved, and the reliability of uplink transmission is improved.

[0138] Referring to Figure 3 , the embodiments of the present application provide a transmission method executed by a network side device, characterized by comprising:

[0143] (2) whether to close or open beam correspondence for each uplink carrier of the terminal;

[0144] (3) the carrier on which beam correspondence is closed;

[0145] (4) whether the terminal uses downlink reception beam to determine or decide uplink transmission beam information;

[0146] (5) whether the terminal needs to perform uplink beam sweeping.

[0147] In the embodiments of the present application, the second information further indicates that the terminal receives and / or transmits through the repeater or directly through the network side device.

[0148] In the embodiments of the present application, the method further includes sending power information, wherein the power information includes target power received by the network side device.

[0149] In the embodiments of the present application, the problem of uplink transmission failure caused by the traditional method of determining the uplink beam only through the downlink beam is solved, and the reliability of uplink transmission is improved.

[0152] It can be understood that the first network side device can be a base station of a source cell, and the second network side device can be a base station of a target cell.
