[0175] In some embodiments, the maximum number of beams transmitted simultaneously is the second number, and the time domain resources occupied by the beams indicated by the first indication information do not overlap.

[0176] In some embodiments, the repeater obtains the first indication information and parses the obtained first indication information to obtain multiple beams.

[0177] In some embodiments, the repeater parses the obtained first indication information to obtain beam IDs of multiple beams and time domain resources occupied by the beams.

[0178] In some embodiments, time domain resources of different beams in the multiple beams do not overlap.

[0179] In some embodiments, if the maximum number of beams simultaneously transmitted by the repeater is the second number, the time domain resources occupied by the beams indicated by the first indication information do not overlap. In some embodiments, if the maximum number of beams simultaneously transmitted by the repeater is the second number, the time domain resources occupied by the beams indicated by the first indication information do not overlap.

[0180] In some embodiments, the repeater has a capability of transmitting a maximum number of beams of a second number at the same time. In some embodiments, the repeater supports transmitting a maximum number of beams of a second number at the same time.

[0181] In some embodiments, the maximum number of beams that the repeater can simultaneously transmit in an access link is a second number. In some embodiments, the maximum number of beams that the repeater supports simultaneously transmitting in an access link is a second number. In some embodiments, the repeater has the capability to simultaneously transmit a maximum number of beams of the second number in an access link.

[0182] In some embodiments, the first indication information includes any one of RRC or DCI or MAC CE.

[0183] In some embodiments, the maximum number of beams transmitted simultaneously by the repeater is a second number, and the repeater does not expect the time domain resources occupied by the beams indicated by the first indication information to overlap.

[0184] In an embodiment of the present disclosure, the maximum number of beams sent simultaneously by the repeater is the second number. In this case, the repeater does not expect the time domain resources occupied by the beams indicated by the first indication information sent by the network device to overlap.

[0185] For example, the beams indicated by the first indication information include beam 1, beam 2 and beam 3, beam 1 occupies time domain resource 1, beam 2 occupies time domain resource 2, beam 3 occupies time domain resource 3, and time domain resource 1, time domain resource 2 and time domain resource 3 do not overlap or conflict.

[0186] In some embodiments, the second number is 1. In some embodiments, the maximum number of beams that the repeater transmits simultaneously is 1. In some embodiments, the maximum number of beams that the repeater transmits simultaneously in an access link is 1.

[0187] In the embodiment of the present disclosure, the repeater can send one beam at a time, so the time domain resources occupied by the beams indicated by the first indication information cannot overlap or conflict.

[0188] In some embodiments, if the maximum number of beams simultaneously transmitted by the repeater is the second number, the repeater does not expect that the time domain resources occupied by the beams indicated by the first indication information do not overlap. In some embodiments, if the maximum number of beams simultaneously transmitted by the repeater is the second number, the repeater does not expect that the time domain resources occupied by the beams indicated by the first indication information do not overlap.

[0189] In some embodiments, the second number is not indicated, the second number is 1; or, the second number is indicated as 1.

[0190] In the embodiment of the present disclosure, if the second number is not indicated, the repeater defaults the second number to be 1. Alternatively, if the second number is indicated to be 1, the repeater determines that the second number is 1 according to the indication.

[0191] In some embodiments, the second quantity is indicated by the network device, or by OAM, or by other means, which is not limited in the embodiments of the present disclosure. Optionally, the network device sends indication information to the repeater, and the indication information is used to indicate the second quantity. Optionally, OAM sends indication information to the repeater, and the indication information is used to indicate the second quantity. In some embodiments, the indication information can be the configuration information in the above-mentioned embodiments, and please refer to the configuration information in the above-mentioned embodiments for details. Optionally, the indication information can also be referred to as configuration information, indication signaling, etc., which is not limited in the embodiments of the present disclosure.

[0192] In some embodiments, the number of beams with overlapping resources indicated by the first indication information is not greater than the first number.

[0193] In some embodiments, the maximum number of beams simultaneously transmitted by the relay is a first number, and the number of beams whose resources overlap as indicated by the first indication information is no greater than the first number. Alternatively, the first indication information can also be understood as indicating that the number of beams whose resources overlap as indicated by the first indication information is no greater than the first number.

[0194] In some embodiments, if the maximum number of beams simultaneously transmitted by the relay is a first number, the number of beams whose occupied resources overlap indicated by the first indication information is no greater than the first number. In some embodiments, if the maximum number of beams simultaneously transmitted by the relay is a first number, the number of beams whose occupied resources overlap indicated by the first indication information is no greater than the first number.

[0196] In some embodiments, the maximum number of beams that the repeater can simultaneously transmit in an access link is a first number. In some embodiments, the maximum number of beams that the repeater supports simultaneously transmitting in an access link is a first number. In some embodiments, the repeater has the capability to simultaneously transmit a maximum number of beams that is a first number in an access link.

[0197] In some embodiments, the maximum number of beams transmitted simultaneously by the repeater is a first number, and the repeater does not expect that the number of beams with overlapping resources indicated by the first indication information is no greater than the first number.

[0198] In an embodiment of the present disclosure, the maximum number of beams sent simultaneously by the repeater is the first number. At this time, the repeater does not expect that the number of beams with overlapping resources indicated by the first indication information sent by the network device is not greater than the first number.

[0199] For example, the first number is 4, and the beams indicated by the first indication information include beam 1, beam 2 and beam 3. Beam 1 occupies time domain resource 1, beam 2 occupies time domain resource 2, and beam 3 occupies time domain resource 3. Time domain resource 1, time domain resource 2 and time domain resource 3 overlap or conflict. The number of three beams is less than the first number, which meets the requirements.

[0200] In some embodiments, the first number is greater than 1. In some embodiments, the maximum number of beams simultaneously transmitted by the repeater is greater than 1. In some embodiments, the maximum number of beams simultaneously transmitted by the repeater in an access link is greater than 1.

[0201] In an embodiment of the present disclosure, the repeater can send multiple beams simultaneously, and the number of beams with overlapping resources indicated by the first indication information is not greater than the first number.

[0202] For example, if the maximum number of beams transmitted simultaneously by the repeater is 4, when the network device indicates the beams through the first indication information, the number of beams with overlapping time domain resources should not be greater than 4. In other words, the maximum number of beams with overlapping time domain resources indicated by the first indication information is 4.
