Abstract

Description
Technical Field
The embodiment of the application relates to the technical field of communication, in particular to a transmission method, a transmission device, transmission equipment and a readable storage medium.
Background
The fifth generation mobile communication technology (5G) high-frequency millimeter wave employs beams for transmission and reception, and introduces a beam reciprocity (beam reciprocity) concept, i.e., a millimeter wave terminal can determine a transmission beam direction or a general direction of a transmission beam through a reception beam.
For example, during random access, after the terminal determines the downlink beam direction by measuring the downlink reference signal, the terminal initiates random access by adopting the uplink beam direction corresponding to the downlink beam, so as to ensure the signal quality and the access success rate of the uplink access.
Due to the limited coverage of the millimeter waves, the adoption of a power amplifier to amplify the signals is an effective means for improving the coverage of the millimeter waves. As shown in fig. 1a, the terminal is under the coverage of the amplifier, and according to the prior art, the terminal measures the downlink beam and transmits the uplink signal (e.g. random access) in the uplink beam direction corresponding to the downlink beam.
However, for a scenario where the uplink and downlink operate at different frequencies, a problem may arise if the amplifier only supports downlink signal or uplink signal amplification. The scenario is exemplified as follows:
1. the downlink of the base station adopts millimeter wave 28GHz, the uplink adopts frequency below 6GHz to supplement uplink coverage, and the amplifier only supports 28GHz millimeter wave frequency band;
2. a base station adopts a Supplementary Uplink (SUL) technology, works in an SUL frequency band below 28GHz TDD frequency band and 6GHz, and an amplifier only supports 28GHz millimeter wave frequency band;
3. the uplink of the base station adopts a 28GHz millimeter wave frequency band, the downlink adopts a frequency below 6GHz, and the amplifier only supports the 28GHz millimeter wave frequency band.
As in the above three scenarios, since the repeater cannot support simultaneous amplification of the uplink and downlink signals, the terminal under the coverage of the amplifier cannot determine the uplink beam transmission direction through the downlink beam direction by using the beam correlation characteristic (as shown in fig. 1b and fig. 1 c). If according to the prior art, the uplink transmission of the terminal will fail.

Referring to fig. 2, an embodiment of the present application provides a transmission method, which is executed by a terminal, and includes the specific steps of: step 201 and step 202.
Step 201: receiving first information and/or second information sent by a network side;
step 202: transmitting according to the first information and/or the second information;
wherein the first information indicates a beam reciprocity (beam reciprocity) to be turned off or on, and the second information indicates a frequency band or a frequency supported by a repeater.
In an embodiment of the application, the first information further indicates one or more of:
(1) whether the uplink and downlink beams of the terminal are different, namely whether the terminal can determine the uplink transmitting beam according to the downlink receiving beam;
(2) whether each uplink carrier of the terminal is closed or opened is judged;
(3) closing the carrier of the beam correspondance;
(4) whether the terminal adopts the downlink receiving wave beam to judge or determine the information of the uplink sending wave beam;
(5) whether the terminal needs to perform uplink beam scanning.
In this embodiment of the present application, the second information further indicates that the terminal performs receiving and/or sending through a repeater or directly through a network side device.
In the embodiment of the present application, if the first information includes: closing the beam correspondence, 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 the uplink, the method further includes:
and closing the beam correspondance of the terminal, or the terminal cannot judge or determine an uplink transmission beam through a downlink receiving beam, or whether the terminal needs to perform uplink beam scanning.
That is, the terminal cannot determine the uplink transmission beam using the downlink reception beam, and needs to transmit the uplink in an attempt-by-attempt manner, i.e., uplink beam scanning. Because the terminal does not have the beam correction 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 scanning.
In this embodiment of the present application, the transmitting according to the first information and/or the second information includes:
if the terminal turns off the beam correspondance and does not receive a response message (e.g., message 2(MSG2)) after the terminal transmits a first message (e.g., message 1(MSG1)), uplink beam scanning is performed and the terminal attempts to transmit the first message on other beams.
In an embodiment of the present application, the method further includes:
receiving power information sent by a network side, wherein the power information comprises: target power received by the network side;
and selecting corresponding target power to calculate uplink transmitting power according to one or more items in the communication relation between the terminal and the repeater and the corresponding relation between the uplink carrier or the frequency and the target power.
In the embodiment of the application, the communication relationship between the terminal and the repeater indicates whether the terminal is in the coverage of the repeater, or whether the received and/or transmitted signal is amplified or forwarded by the repeater, or whether the received and/or transmitted signal is connected or accessed by the repeater.
In an embodiment 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.
Referring to fig. 5, how to determine the uplink transmission power of the terminal 1 and the terminal 2 will be described.
PPRACH，b，fc(i)＝min{PCMAX，f，c(i)，PPRACH，target，f，c+PLb，f，c}[dBm]
PCMAX，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 power of the terminal 1 and the configured maximum transmission power of the terminal 2 are the same.
PPRACH，target，f，cIs the target power received by the network side.
PLb，f，cThe path loss is the path loss (the transmission Power of the downlink Reference Signal-Reference Signal Received Power RSRP), the terminal 1 is located at the partial edge of the cell coverage, and the terminal 2 is located under the coverage of the repeater, so the path loss calculated by the terminal 1 is large, and the path loss calculated by the terminal 2 is small. However, the actual terminal 2 is farther away from the base station, and each uplink carrier in the prior art transmits a target received power.
PPRACH，b，fc(i) The power of a Physical Random Access Channel (PRACH) is transmitted, and through calculation, the transmission power of the terminal 2 is low, which results in uplink transmission failure.
Therefore, for a scenario where a repeater exists, different target powers need to be transmitted on the same uplink carrier or frequency, that is, different target powers need to be transmitted for whether the repeater exists, that is:
(1) the terminal 1 calculates the transmission power by adopting the target power 1 transmitted by the network side;
(2) the terminal 2 calculates the transmission power using the target power 2 transmitted by the network side.
Target power 1: preambleReceivedTargetPower;
target power 2: preambleReceivedTargetPower-repeat.
By setting different target sending powers, the network side can compensate the problem that path loss cannot be estimated through downlink RSRP due to the existence of a repeater, and the failure of uplink sending of the terminal is avoided.
In this embodiment of the present application, the transmitting according to the first information and/or the second information includes:
according to the first information, selecting an uplink carrier or frequency which does not indicate to close the beam correspondance or indicate to open the beam correspondance to send uplink; and/or selecting the uplink carrier or frequency supported by the repeater to transmit uplink according to the second information.
In the prior art, a terminal selects an uplink carrier according to downlink RSRP, so that an uplink carrier which is not supported by a repeater may be selected, and a beam correlation capability cannot be adopted, and at this time, the terminal should select or a network should schedule an uplink carrier or a frequency which is supported by the repeater to transmit an uplink.
In an embodiment of the present application, the method further includes:
receiving a handover command from a network side device, the handover command indicating one or more of:
(1) the terminal is switched to a cell with a repeater;
(2) the terminal is switched to a repeater amplified beam;
(3) the terminal is switched to a frequency band or frequency supported by the current cell repeat to initiate random access;
(4) and the terminal is switched to the target cell and the uplink random access carrier, and the beam correspondance capability is closed.
In the embodiment of the application, the problem of uplink transmission failure caused by the fact that the uplink beam is determined only through the downlink beam in the prior art is solved, and the reliability of uplink transmission is improved.
Referring to fig. 3, an embodiment of the present application provides a transmission method, which is executed by a network side device, and includes:
step 301: sending the first information and/or the second information;
wherein the first information indicates to close or open the beam correspondence, and the second information indicates the frequency band or frequency supported by the repeater.

(1) whether uplink and downlink beams of the terminal have mutual difference or not;
(2) whether each uplink carrier of the terminal is closed or opened is judged;
(3) closing the carrier wave of the beam correspondence;

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

In an embodiment of the present application, the method further includes: transmitting power information, the power information comprising: the target power received by the network side device.
In the embodiment of the application, the problem of uplink transmission failure caused by the fact that the uplink beam is determined only through the downlink beam in the prior art is solved, and the reliability of uplink transmission is improved.
Referring to fig. 4, an embodiment of the present application provides a transmission method, which is executed by a first network side device, and includes the specific steps of: step 401 and step 402.
Step 401: receiving third information sent by second network side equipment;
it is to be understood that the first network-side device may be a base station of a source cell, and the second network-side device may be a base station of a target cell.
Step 402: performing switching judgment and/or sending a switching command according to the third information;
wherein the third information indicates one or more of: (1) whether a repeater is present; (2) frequency bands or frequencies supported by the repeater; (3) the repeater amplified beam information.
