Discussion on Multi-PUSCH Configuration for UTO-UCI Content Moderator at Ericsson

This discussion encompasses the configuration and implications of the Multi-PUSCH setup based on agreed parameters within the UTO-UCI content moderation context at Ericsson. It delves into varying configurations, potential impacts, and considerations for effective utilization. The slides provide insights into key aspects such as window configurations, signaling indications, and the challenge of mis-detection in the context of packet arrival. Overall, the content sheds light on optimizing configurations for improved performance and operational efficiency in UTO-UCI content moderation processes.

7. Option B Impact of mis-detection Can not solve late arrival of packet Can not predict arrival of next XR packet Cannot confirm the usage | ESORFAL Sorour Falahati | 2022-12-20 | Ericsson Internal | Page 7 of 16

8. Sliding indicator within a window Option A-1 Window fixed in time Option A-1a Window fixed in number of TOs Option A-1b Configure the RRC parameter UTO_period. Configure the RRC parameter Nu (Nu is the size of bit- map) FFS range value of UTO_period Alt-1: values in time unit (e.g., XR traffic periodicity) FFS range value of Nu Alt -2: multiple of CG periodicity given by integer values (n=1, 2, ..) For every Nu consecutive and valid CG PUSCH TOs, starting from the first CG PUSCH in the first period of the CG configuration: The starting time of the first period of UTO periodicity starts at the same as starting time of the first period of the CG configuration and ends after UTO_period. The next UTO period(s) are followed after the first UTO period. A transmitted CG PUSCH among the Nu CG PUSCH TOs, carries UTO-UCI that is applicable to the Nu CG PUSCH TOs. A transmitted CG PUSCH that is confined within a UTO period, carries UTO-UCI that is applicable to the CG PUSCH TOs within the UTO period. | ESORFAL Sorour Falahati | 2022-12-20 | Ericsson Internal | Page 8 of 16

9. Sliding indicator within a window Option A-2 Window fixed in number of TOs Option A-2b Window fixed in time Option A-2a Configure the RRC parameter UTO_period. Configure the RRC parameter Nu (Nu is the maximum size of the bit-map) FFS range value of UTO_period FFS range value of Nu Alt-1: values in time unit (e.g., XR traffic periodicity) Alt -2: multiple of CG periodicity given by integer values (n=1, 2, ..) Configure the RRC parameter UTO_offset. FFS range value of UTO_offset Configure the RRC parameter UTO_offset. For every Nu consecutive and valid CG PUSCH TOs, starting from the first CG PUSCH in the first period of the CG configuration: FFS range value of UTO_offset The starting time of the first period of UTO periodicity starts at the same as starting time of the first period of the CG configuration and ends after UTO_period. The next UTO period(s) are followed after the first UTO period. A transmitted CG PUSCH among the Nu CG PUSCH TOs, carries UTO-UCI that is applicable to the valid CG PUSCH TOs starting from the Nd:th CG PUSCH TO after the transmitted CG PUSCH and ending with the last TO among the Nu valid CG PUSCH TOs. A transmitted CG PUSCH that is confined within a UTO period, carries UTO- UCI that is applicable to the CG PUSCH TOs within the UTO period and after UTO_offset from the end of the transmitted CG PUSCH. | ESORFAL Sorour Falahati | 2022-12-20 | Ericsson Internal | Page 9 of 16

Configure the RRC parameter Nu (Nu is the size of bit-map) FFS range value of UTO_period FFS range value of Nu Alt-1: values in time unit (e.g., XR traffic periodicity) Nd is the size of offset in number of TOs Alt -2: multiple of CG periodicity given by integer value (n=1, 2, ..) Alt-1: Nd is provided by configuration. UTO_offset is the offset value. FFS range value of Nd Alt-1: UTO_Offset is provided by configuration. FFS range value of UTO_offset Alt-2: Nd= 1 Alt-2: UTO_Offset = 0 A transmitted CG PUSCH, carries UTO-UCI that is applicable to the Nu consecutive and valid CG PUSCH TOs, starting from the Nd:th [valid] CG PUSCH TO(s) after the transmitted CG PUSCH. A transmitted CG PUSCH carries UTO-UCI that is applicable to the valid CG PUSCH TOs that are confined within UTO_period starting with UTO_offset from the end of the transmitted CG PUSCH. | ESORFAL Sorour Falahati | 2022-12-20 | Ericsson Internal | Page 10 of 16

11. UTO-UCI information For a CG configuration with UTO-UCI indication enabled, select one of the following alternatives: Alt-1-1) The UTO-UCI includes a bit-map of Nu bits. Nu is configured. o FFS: range values of Nu Alt-1-2) The UTO-UCI includes a bit-map of maximum Nu bits. Nu is configured. o FFS: range values of Nu Alt-2-1) The UTO-UCI includes an index to an RRC configured bit-map. The bit-maps in the table have the same size. o FFS on maximum number of rows, and maximum size of a bit-map in the table Alt-2-2) The UTO-UCI includes an index to an RRC configured bit-map. The bit-maps in the table can have different sizes. o FFS on maximum number of rows, and maximum size of a bit-map in the table Note: A bit in the bit-map with value 1 implies that the corresponding CG PUSCH TO is indicated as unused . A bit in the bit-map with value 0 implies that the corresponding CG PUSCH TO is indicated as NOT unused . FFS on whether/how to extend to multiple CG configurations | ESORFAL Sorour Falahati | 2022-12-20 | Ericsson Internal | Page 11 of 16
