Sub-sampled DMRS are utilised in repeated mini-slots for PUSCH transmission. Each sub-sampled DMRS may be multiplex with data in the respective symbol.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for configuring a temporal position of DeModulation Reference Symbols (DMRS) in sidelink transmissions of UEs in a cellular communications network, the method comprising: configuring in a cellular communications network a plurality of DMRS temporal position configurations, selecting a DMRS temporal position configuration, transmitting a sidelink control information (SCI) message to a UE including an indication of the selected DMRS temporal position configuration, and transmitting data from the UE comprising DMRS in the temporal positions indicated by the configuration, wherein the DMRS temporal position configurations are transmitted to the UEs by higher layer signaling that comprises Radio Resource Control (RRC) signaling. 2. The method according to claim 1 , wherein the plurality of DMRS temporal position configurations are stored in at least one preconfigured table. 3. The method according to claim 2 , wherein the indication of the selected DMRS temporal position configuration is an index to an entry in the at least one preconfigured table. 4. The method according to claim 2 , wherein one of the at least one preconfigured table comprises options for a number of additional DMRS positions to be used in a transmission. 5. The method according to claim 2 , wherein one of the at least one preconfigured table comprises options for a position of additional DMRS positions in a transmission. 6. The method according to claim 2 , wherein one of the at least one preconfigured table comprises options for a sub-sampling factor for DMRS signals in a transmission. 7. The method according to claim 2 , wherein the at least one preconfigured table comprises a single table. 8. The method according to claim 1 , wherein the plurality of DMRS temporal position configurations are stored at each relevant UE of the cellular communications network. 9. The method according to claim 1 , wherein the data is transmitted on a Physical Sidelink Shared Channel (PSSCH) associated with the SCI message. 10. The method according to claim 1 , wherein the data is transmitted in a plurality of aggregated mini-slots and the DMRS temporal position configuration applies across the aggregated mini-slots. 11. The method according to claim 1 , wherein the sidelink control information (SCI) is transmitted from a base station to the UE.
