[0003] Mobile communications have evolved significantly from early voice systems to today's highly sophisticated, integrated communications platforms. The next generation wireless communications system, 5G, or new radio (NR), will provide access to information and data sharing anywhere, anytime by a variety of users and applications. NR is expected to be a unified network / system that meets widely varying targets, sometimes competing on performance specifications and services. These diverse and multidimensional requirements are growing across different service and application areas. In general, NR will evolve with future new radio access technologies (RATs) based on 3GPP LTE-Advanced to enrich people's lives with better, simpler, and seamless wireless connectivity solutions. NR will enable everything to be connected wirelessly and deliver rich content and services at high speeds.

[0004] One challenge for 5G NR systems is transmitting HARQ-based PSDCH, especially for higher carrier frequency operation (i.e., carrier frequencies above 52.6 GHz), as larger subcarrier spacing (SCS) is available along with shorter slot durations. [Brief explanation of the drawings]

[0127] Various embodiments herein assume that multiple PDSCHs may be scheduled by DCI, and therefore, HARQ-ACK transmissions Related technologies Considering the potential limitations on multi-PDSCH scheduling due to codebook size reduction, embodiments provide a method for multi-PDSCH scheduling in systems operating above 52.6 GHz carrier frequencies. quasi for generating static HARQ-ACK codebooks technology Includes. A DCI may be able to schedule one or more PDSCHs using separate TBs. The number of PDSCHs scheduled by a DCI may be explicitly indicated by a field within the DCI. Alternatively, the number of PDSCHs scheduled by a DCI is coded together with other information field(s). for example , time domain resources allocation The number of scheduled PDSCHs for a row in the (TDRA) table is equal to the number of configured SLIVs for the row. The maximum number of PDSCHs scheduled by a multi-TTI DCI is the maximum number of PDSCHs scheduled among all rows, and for a row in the TDRA table, each SLIV may be configured in a different slot. Alternatively, one or more SLIVs may be configured in the same slot.

[0129] The Type 1 HARQ-ACK codebook can be extended to support HARQ-ACK feedback for multiple PDSCHs scheduled by multi-PDSCH DCI. It is necessary to include HARQ-ACK bits for all potential PDSCHs indicated by the SLIVs of a row in the TDRA table. Meanwhile, multiple limiting factors for multi-PDSCH scheduling can be used to reduce the codebook size.

[0130] PDSCH transmissions scheduled by different DCIs are not interleaved

[0131] In the case of multi-PDSCH scheduling, PDCCH and Scheduled The timing relationship between the PDSCH and schedule In a cell where a UE is scheduled using a second PDCCH, a first PDSCH is scheduled by the first PDCCH. schedule The PDCCH starts earlier than the end of the last PDSCH to be transmitted and uses the first PDCCH. schedule The first PDSCH is transmitted by the second PDCCH. schedule It can be defined that the PDSCH is not expected to start earlier than the end of the last PDSCH received. In this way, the first DCI scheduleThe PDSCH(s) to be transmitted are determined by the second DCI. schedule The PDSCH may not be interleaved with the PDSCH(s) to be transmitted.

[0132] 12 shows an example of valid and invalid multi-PDSCH scheduling with two PDCCHs. Based on the above, timing relationship 1202 is considered valid scheduling, and timing relationship 1204 is invalid scheduling. K1 In the set of Value in
