Abstract: Systems and methods of a wireless communications system using signals not traditionally used for positioning purposes for positioning measurements in both uplink (UL) and downlink (DL) are described herein. A user equipment (UE) may generate a UE capability information message indicating one or more signal types that the UE can process for DL positioning measurements and/or that the UE can send for UL positioning measurements. The one or more signal types so indicated may include signals not traditionally used for positioning measurements. The UE may send, to the base station, the UE capability information message. The wireless communications system may then configure the base station and/or the UE to use such signal types with one or more positioning methods. In some embodiments, the base station may also indicate to the UE a subset of signals of an indicated type which should be processed for DL measurements/sent for UL measurements.

Abstract: An approach to communication by a user equipment (UE) in a wireless communication system that includes the UE sending an RRC setup request message including a paging offset value to a base station. The UE receives an RRC setup message from the network node, the RRC setup message including a PS-paging offset value and a PS-P-RNTI value associated with the UE. Energy conservation approaches for use with paging are described, including paging occasion monitor reporting and configuration, paging-offset reporting, the use of a paging monitoring skipping signal, and the use of dynamic TRS triggering for paging reception.

Abstract: Some embodiments include an apparatus, method, and computer program product for facilitating processing times in a 5G wireless communications system. When operating at higher frequency subcarrier spacing (SCS), slot times for receiving and/or transmitting data between user equipment (UE) and a 5G Node B (gNB) become shorter. Because of this, some UE may face difficulty in processing physical downlink shared channel (PDSCH), physical uplink shared channel (PUSCH), and/or physical downlink control channel (PDCCH) data with sufficient speed. To address potential limitations, a flexible minimum processing time may be used to accommodate different UE processing capabilities. The UE may report its processing capabilities to the gNB. The gNB may then schedule communications according to the UE’s processing capabilities. The gNB may consider whether the UE implements a single or multiple processing engines. Further, the gNB may apply single-slot and/or multi-slot scheduling techniques to also prevent timing issues.

Abstract: Some embodiments include an apparatus, method, and computer program product for enhanced Hybrid Automatic Repeat Request (HARQ)-ACK in a fifth generation (5G) wireless communications system. A user equipment (UE) can receive, during a HARQ-ACK window, a semi-persistent scheduling (SPS) Physical Downlink Shared Channel (PDSCH) transmission or a Physical Downlink Control Channel (PDCCH) transmission corresponding to a SPS PDSCH release. The UE can generate a Hybrid Automatic Repeat Request (HARQ)-ACK information bit corresponding to the reception. The UE can be configured with an offset value, k, and a length, l, of the HARQ-ACK window associated with an uplink transmission slot n, of a Physical Uplink Control Channel (PUCCH) transmission, and determine a starting slot of the HARQ-ACK window as n−k. When a corresponding valid uplink transmission slot is not available, the UE can transmit the HARQ-ACK information bit in the uplink transmission slot n of the PUCCH transmission.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing resource allocations for feedback channels in sidelink communications. A UE can be configured to receive a physical sidelink control channel (PSCCH) transmission or a physical sidelink shared channel (PSSCH) transmission over a sidelink between the UE and a second UE for sidelink communication. The UE can allocate a set of resource elements within an interlace including multiple resource blocks to carry physical sidelink feedback channel (PSFCH) content associated with the received PSCCH transmission or PSSCH transmission, where the set of resource elements includes a first resource element in a first resource block of the interlace, and a second resource element in a second resource block of the interlace. The UE can be further configured to transmit the PSFCH content carried by the set of resource elements as a PSFCH transmission to the second UE.
