  • Patent number: 11895633
    Abstract: Embodiments include methods in a communication system including host computer, base station, and UE. The base station can send the UE an indication of an active bandwidth part (BWP) of a size NZBWP,1size frequency-domain resource blocks (RBs), and select frequency-domain RBs, within the active BWP, to be assigned for carrying the user data to the UE. The base station can encode an indication of the selected frequency-domain RB(s) represented by a starting virtual RB, RBstart, and a length of contiguously allocated RBs, LRBs, using a number of bits. The number is a plurality and related to a size NBWP,2size of another BWP than the active BWP. NBWP,2size is smaller than NBWP,1size. The starting virtual RB is encoded with a resolution of K RBs, with K determined based on a ratio of NBWP,1size and NBWP,2size. The base station can send the encoded indication to the UE via a downlink control channel.

  • Publication number: 20240015732
    Abstract: Systems and methods for aperiodic Channel State Information (CSI) over multi-Transmission/Reception Point (TRP) Physical Uplink Shared Channel (PUSCH) are provided. In some embodiments, a method performed by a wireless device for providing feedback includes: repeating PUSCH over multiple M>1 PUSCH occasions with P spatial relations and/or Uplink Transmission Configuration Indicator (TCI) states; and multiplexing Aperiodic CSI (A-CSI) with PUSCH on N>=1 PUSCH transmission occasions wherein N includes at least one PUSCH transmission occasion associated with each of the P spatial relations or UL TCI states. This may enable improved A-CSI reliability in multi-TRP scenarios. By repeating A-CSI (multiplexed with PUSCH or not multiplexed with PUSCH) over multiple TRPs, the reliability of A-CSI can be improved since the A-CSI can be received by at least one TRP. This method is particularly beneficial in FR2 cases where the channel between a TRP and a UE can experience channel blocking.
