Abstract: This disclosure relates to techniques for configuring, performing, and reporting neighbor cell measurements in a wireless communication system. A base station of a serving cell may provide configuration information relevant to performing layer 1 (L1) measurements based on reference signals of one or more neighbor cells. A UE may perform L1 inter-frequency measurements of the neighbor cell(s) based on the configuration. The UE may report the measurements.

Abstract: Methods, systems, and devices for wireless communications are described. To monitor a PDCCH for CA, a UE may receive PDCCH candidates in a plurality of configured component carriers (CCs). In response to a determination that a maximum number of virtual CCs that the UE is capable of monitoring for PDCCH is smaller than a number of the plurality of configured CCs, the UE groups the plurality of configured CCs into CC groups based at least in part on SCS numerologies and PDCCH monitoring configurations corresponding to span patterns within a slot of a DL subframe. The UE determines a maximum number of blind decoding operations and non-overlapped CCEs for each of the CC groups. The UE then monitors at least a first portion of the PDCCH candidates based on the maximum number of blind decoding operations and non-overlapped CCEs for each of the CC groups.

Abstract: Systems and methods for modularized design for inter-physical layer priority uplink control information (UCI) multiplexing are disclosed herein. A user equipment (UE) may determine a first code rate for a first portion of UCI and a second code rate for a second portion of UCI. Different code rates may be used to encode different portions of UCI (e.g., hybrid automatic repeat request acknowledgement (HARQ-ACK) bits, channel state information (CSI) reporting bits, scheduling request (SR) bits, cyclic redundancy check (CRC) bits, etc.). Further, a UE may select a group of bets offset sets based on a physical layer priority type and a UCI multiplexing type.

Abstract: Systems and methods for associating phase tracking reference signal (PTRS) and demodulation reference signal (DMRS) ports for multi-beam physical uplink shared channel (PUSCH) transmissions are described herein. A base station may provide, to a user equipment (UE), PTRS and DMRS port associations for the multiple beams on which the PUSCH is transmitted. In some cases, a 2-bit downlink control information (DCI) field may be used to alternatively provide single beam or multiple beam PTRS and DMRS port associations to a UE. For non-codebook (NCB) based transmissions, the UE may alternatively determine PTRS and DMRS port associations for multiple beams independently of any PTRS and DMRS port association indicated in DCI.

Abstract: A method for Resource Allocation for Msg-3 Transmission on an unlicensed spectrum may include receiving a random access response (RAR) grant comprising a 12-bit frequency domain resource allocation (FDRA) field. If the resource allocation type is type-1 some embodiments may zero padding the FDRA field to interpreting the 12-bit FDRA and determine a starting position of allocated resources where a Scheduled PUSCH Transmission is transmitted in an unlicensed spectrum. Some embodiments may use a virtual Bandwidth Part (BWP) to obtain a starting position and a length of allocated resources.

Abstract: A method, UE and integrated circuit for reporting RSTD values to a network. A user equipment (UE) is configured to establish a connection to a network, the network comprising a first cell and a second cell. The UE receives a positioning reference signal from each of the first and second cells, determines a frequency band for each of the positioning reference signals, determines reference signal time difference (RSTD) values from measured time offsets between the positioning reference signals from the first and second cells, determines RSTD reporting values based on at least the RSTD values and the determined frequency bands and transmits an indication of the RSTD reporting values to the network.

Abstract: A terminal may include a transmitter that transmits, to a base station, a terminal capability indicating support for a first type of measurement configuration or a second type of measurement configuration. The terminal may include a receiver that receives, from the base station, network configuration information representative of a mapping between the first type of measurement configuration and the second type of measurement configuration. The terminal may include a processor that, based on the mapping, transforms the first type of measurement configuration to the second type of measurement configuration or transforms the second type of measurement configuration to the first type of measurement configuration. The network configuration information may be based on an independent frequency range (FR) measurement and a network preference included in the terminal capability.
