User equipments, base stations, and methods
A method by a user equipment (UE) is described. The method includes receiving, from a base station, a random access response (RAR), wherein the RAR contains a RAR uplink (UL) grant scheduling a PUSCH transmission; and determining, for the PUSCH transmission, a frequency hopping mode from two frequency hopping modes, intra-slot frequency hopping and inter-slot frequency hopping, wherein in a first case that the PUSCH transmission is scheduled with repetitions across multi-slots, the inter-slot frequency hopping is determined for the PUSCH transmission, in a second case that the PUSCH transmission is scheduled without repetition, the intra-slot frequency hopping is determined for the PUSCH transmission.
1 . A user equipment (UE), comprising:
reception circuitry configured to receive, from a base station, a random access response (RAR), wherein the RAR contains a RAR uplink (UL) grant scheduling a PUSCH transmission; and
control circuitry configured to determine, for the PUSCH transmission, a frequency hopping mode from two frequency hopping modes, intra-slot frequency hopping and inter-slot frequency hopping, wherein
in a first case that the PUSCH transmission is scheduled with repetitions across multi-slots, the inter-slot frequency hopping is determined to be applicable for the PUSCH transmission, and a frequency offset for a PUSCH repetition transmitted in a slot with an odd slot number is given based on an initial UL BWP size, the initial UL BWP size being equal to or less than a bandwidth that the UE can support, and
in a second case that the PUSCH transmission is scheduled without repetition, the intra-slot frequency hopping is determined to be applicable for the PUSCH transmission.
2 . The UE of claim 1 , wherein
the frequency offset is an offset between the PUSCH repetition transmitted in the slot with the odd slot number and a PUSCH repetition transmitted in a slot with an even slot number.
3 . The UE of claim 1 , wherein
in the first case, a frequency hopping flag field included in the RAR UL grant is used to indicate whether the determined inter-slot frequency hopping is enabled or disabled for the PUSCH transmission,
in the second case, the frequency hopping flag field is used to indicate whether the determined intra-slot frequency hopping is enabled or disabled for the PUSCH transmission.
4 . A base station, comprising:
transmission circuitry configured to transmit, to a user equipment (UE), a random access response (RAR), wherein the RAR contains a RAR uplink (UL) grant scheduling a PUSCH transmission; and
control circuitry configured to determine, for the PUSCH transmission, a frequency hopping mode from two frequency hopping modes, intra-slot frequency hopping and inter-slot frequency hopping, wherein
in a first case that the PUSCH transmission is scheduled with repetitions across multi-slots, the inter-slot frequency hopping is determined to be applicable for the PUSCH transmission, and a frequency offset for a PUSCH repetition transmitted in a slot with an odd slot number is given based on an initial UL BWP size, the initial UL BWP size being equal to or less than a bandwidth that the UE can support, and
in a second case that the PUSCH transmission is scheduled without repetition, the intra-slot frequency hopping is determined to be applicable for the PUSCH transmission.
5 . The base station of claim 4 , wherein
the frequency offset is an offset between the PUSCH repetition received in the slot with the odd slot number and a PUSCH repetition received in a slot with an even slot number.
6 . The base station of claim 4 , wherein
in the first case, a frequency hopping flag field included in the RAR UL grant is used to indicate whether the determined inter-slot frequency hopping is enabled or disabled for the PUSCH transmission,
in the second case, the frequency hopping flag field is used to indicate whether the determined intra-slot frequency hopping is enabled or disabled for the PUSCH transmission.
7 . A method performed by user equipment (UE), comprising:
receiving, from a base station, a random access response (RAR), wherein the RAR contains a RAR uplink (UL) grant scheduling a PUSCH transmission; and
determining, for the PUSCH transmission, a frequency hopping mode from two frequency hopping modes, intra-slot frequency hopping and inter-slot frequency hopping, wherein
in a first case that the PUSCH transmission is scheduled with repetitions across multi-slots, the inter-slot frequency hopping is determined to be applicable for the PUSCH transmission, and a frequency offset for a PUSCH repetition transmitted in a slot with an odd slot number is given based on an initial UL BWP size, the initial UL BWP size being equal to or less than a bandwidth that the UE can support, and
in a second case that the PUSCH transmission is scheduled without repetition, the intra-slot frequency hopping is determined to be applicable for the PUSCH transmission.
