Abstract: Embodiments herein provide techniques for indication of a system frame number (SFN) in and/or associated with a random access response (RAR) for a random access procedure. A UE may transmit a physical random access channel (PRACH) preamble in a PRACH occasion (e.g., in a Msg1 or MsgA) and monitor for a message (e.g., Msg2 or MsgB) in a RAR window. The RAR window may be greater than one frame. The Msg2 or MsgB (e.g., a downlink control information (DCI) and/or a medium access control (MAC) RAR) may indicate the SFN associated with the RACH occasion. The UE may determine whether the message is for the UE or another UE based on the SFN. Other embodiments may be described and claimed.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for determining that a first physical uplink control channel (PUCCH) resource and a second PUCCH resource at least partially overlap, where the first PUCCH resource has a payload of a first size carrying a first uplink control information (UCI) in a first format, and the second PUCCH resource has a payload of a second size carrying a second UCI in a second format. Furthermore, the first UCI and the second UCI are multiplexed to form a combined payload to be carried by the first PUCCH resource in the first format or by the second PUCCH resource in the second format. Other embodiments may be described and claimed.

Abstract: Various embodiments herein provide techniques to operate wideband (WB) cells, and in particular, WB operation for New Radio-Unlicensed (NR-U). The embodiments herein provide more accurate and efficient operation of WB procedures with listen-before-talk (LBT) operation as compared with existing and/or previous solutions. In embodiments, a user equipment (UE) may receive configuration information for a search space set that includes multiple monitoring locations in a frequency domain within a listen-before-talk (LBT) bandwidth part (BWP). The UE may monitor for a physical downlink control channel (PDCCH) on one or more of the monitoring locations

Abstract: Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE) to operate in a New Radio (NR) system comprises one or more baseband processors to determine if two or more uplink signals partially overlap, determine a multiplexing rule, a dropping rule, or a priority rule for the two or more uplink signals, and to multiplex, drop, or prioritize the two or more uplink signals for transmission according to the multiplexing rule, dropping rule, or priority rule, and a memory to store two or more uplink signals.

Abstract: Systems and methods for downlink transmission using a wideband unlicensed band carrier in 5G networks are described. The gNB determines, based on LBT, which LBT subchannel(s) in a BWP are available during a COT. The gNB transmits an indication of the available subchannels in DCI format 2_0 of a GC-PDCCH of one of the available subchannels and subsequently transmits a PDSCH using the available subchannel(s). The gNB may configure multiple opportunities during the COT and transmit the GC-PDCCH after the initial opportunity. The PDSCH is transmitted on all available subchannels during the COT and, during an initial portion of the COT, may transmit the PDSCH by puncturing symbols of the unavailable subchannels. The indication may include a bitmap of available subchannels or if the LBT outcome is not available, may indicate all or none of the subchannels or available or that the outcome is not available.

Abstract: Embodiments herein provide techniques for indication of a system frame number (SFN) in and/or associated with a random access response (RAR) for a random access procedure.

The RAR window may be greater than one frame. The Msg2 or MsgB (e.g., a downlink control information (DCI) and/or a medium access control (MAC) RAR) may indicate the SFN associated with the RACH occasion. The UE may determine whether the message is for the UE or another UE based on the SFN. Other embodiments may be described and claimed.

Abstract: Various embodiments herein provide techniques for grant-based and configured grant physical uplink shared channel (PUSCH) transmissions in New Radio (NR) systems operation in unlicensed spectrum. Some embodiments relate to identification, based on an index to a table, a combination of a listen-before talk (LBT) type, an offset, and a channel access priority class (CAPC). Some embodiments relate to selecting, based on a duration of a first uplink (UL) transmission that is to follow a received downlink (DL) transmission, one of CAT-1 LBT and CAT-2 LBT. Other embodiments may be described and/or claimed.
