Abstract

A base station and/or a wireless device may communicate using a plurality of transmission beams. Multiple transmission beams may be used for transmission such that a message may be sent via different transmission beams. Multiple transmission beams may be used for sending multiple repetitions of the message or for sending different portions of the message.

First claim

1 . A method comprising:
receiving, by a wireless device, a message associated with a configured uplink grant, wherein the message comprises:
a first sounding reference signal (SRS) resource indicator (SRI) indicating a first SRS resource of a first SRS resource set; and
a second SRI indicating a second SRS resource of a second SRS resource set different from the first SRS resource set;
transmitting, based on the first SRI, at least one transport block associated with the configured uplink grant; and transmitting, based on the second SRI, at least one repetition of the transport block.

2 . The method of claim 1 , wherein the transmitting the at least one transport block comprises transmitting the at least one transport block using a first spatial domain transmission filter associated with a first spatial relation of the first SRS resource, and wherein the transmitting the at least one repetition of the transport block comprises transmitting the at least one repetition of the transport block using a second spatial domain transmission filter associated with a second spatial relation of the second SRS resource.

3 . The method of claim 1 , further comprising receiving at least one configuration parameter for a cell, wherein the at least one configuration parameter indicates:
the first SRS resource set; and the second SRS resource set.

4 . The method of claim 1 , further comprising:
determining, based on the first SRS resource, a first spatial domain transmission filter for the transmitting the at least one transport block; and determining, based on the second SRS resource, a second spatial domain transmission filter for the transmitting the at least one repetition of the transport block.

5 . The method of claim 1 , further comprising receiving an activation command indicating, for the first SRS resource, a first spatial relation associated with a first spatial domain transmission filter, wherein the transmitting the at least one transport block comprises transmitting the at least one transport block using the first spatial domain transmission filter.

6 . The method of claim 1 , wherein the transmitting the at least one transport block comprises transmitting the at least one transport block using a first spatial domain transmission filter associated with a first default transmission configuration indication (TCI) state, and wherein the transmitting the at least one repetition of the transport block comprises transmitting the at least one repetition of the transport block using a second spatial domain transmission filter associated with a second default TCI state.

7 . The method of claim 1 , wherein:
the transmitting the at least one transport block comprises transmitting at least one first physical uplink shared channel (PUSCH) transmission during at least one first transmission occasion; and the transmitting the at least one repetition of the transport block comprises transmitting at least one second PUSCH transmission during at least one second transmission occasion that is different from the at least one first transmission occasion.

8 . A method comprising:
receiving, by a wireless device, a downlink control information (DCI) message scheduling transmission of a transport block, wherein the DCI message comprises:
a first sounding reference signal (SRS) resource indicator (SRI) indicating a first SRS resource of a first SRS resource set; and
a second SRI indicating a second SRS resource of a second SRS resource set different from the first SRS resource set; and
transmitting, based on the first SRI, the transport block; and transmitting, based on the second SRI, at least one repetition of the transport block.

9 . The method of claim 8 , wherein the transmitting the transport block comprises transmitting the transport block using a first spatial domain transmission filter associated with a first spatial relation of the first SRS resource, and wherein the transmitting the at least one repetition of the transport block comprises transmitting the at least one repetition of the transport block using a second spatial domain transmission filter associated with a second spatial relation of the second SRS resource.

10 . The method of claim 8 , further comprising receiving at least one configuration parameter for a cell, wherein the at least one configuration parameter indicates:
the first SRS resource set; and the second SRS resource set.

11 . The method of claim 8 , further comprising:
determining, based on the first SRS resource, a first spatial domain transmission filter for the transmitting the transport block; and determining, based on the second SRS resource, a second spatial domain transmission filter for the transmitting the at least one repetition of the transport block.

12 . The method of claim 8 , further comprising receiving an activation command indicating, for the first SRS resource, a first spatial relation associated with a first spatial domain transmission filter, wherein the transmitting the transport block comprises transmitting the transport block using the first spatial domain transmission filter.

13 . The method of claim 8 , wherein:
the transmitting the transport block comprises transmitting at least one first physical uplink shared channel (PUSCH) transmission during at least one first transmission occasion; and the transmitting the at least one repetition of the transport block comprises transmitting at least one second PUSCH transmission during at least one second transmission occasion that is different from the at least one first transmission occasion.

14 . The method of claim 8 , further comprising:
determining that the first SRS resource is not associated with a spatial relation and that the second SRS resource is not associated with a spatial relation, wherein the transmitting the transport block is further based on a first transmission configuration indicator (TCI) state, and wherein the transmitting the at least one repetition of the transport block is further based on a second TCI state different from the first TCI state.

15 . A method comprising:
receiving, by a wireless device, a message scheduling transmission of a transport block, wherein the message comprises:
a first sounding reference signal (SRS) resource indicator (SRI) indicating a first SRS resource of a first SRS resource set; and
a second SRI indicating a second SRS resource of a second SRS resource set different from the first SRS resource set;
transmitting, based on the first SRI and during at least one first transmission occasion, the transport block; and transmitting, based on the second SRI and during at least one second transmission occasion different from the first transmission occasion, at least one repetition of the transport block.

16 . The method of claim 15 , wherein the message comprises at least one of:
a configured uplink grant; or a downlink control information (DCI) message.

17 . The method of claim 15 , wherein the transmitting the transport block comprises transmitting the transport block using a first spatial domain transmission filter associated with a first spatial relation of the first SRS resource, and wherein the transmitting the at least one repetition of the transport block comprises transmitting the at least one repetition of the transport block using a second spatial domain transmission filter associated with a second spatial relation of the second SRS resource.

18 . The method of claim 15 , further comprising receiving at least one configuration parameter for a cell, wherein the at
