Abstract: A communication system provides reliable wideband communications with reduced. power consumption in a user equipment (UE) receiver. A UE may include receiver circuitry to receive a radio frequency (RF) signal from a wireless network and output an analog baseband signal. The RF signal includes M copies of a duplicated signal in a frequency domain. The analog baseband signal includes the M copies of the duplicated signal uniformly offset from one another in the frequency domain by a bandwidth F and including a gap between adjacent copies. The UE further includes an anti-aliasing analog filter an analog to digital converter (ADC). The ADC samples an output of the anti-aliasing analog filter at a sampling frequency selected to obtain a digital baseband signal comprising a combined digital copy of the M copies of the duplicated signal folded over each other.

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 LE 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: A user equipment (UE) is served by a serving cell of a network and is configured to measure channel state information reference signals (CSI-RS) from a target cell. The UE receives, from the serving cell, a measurement configuration message indicating the UE is to measure CSI-RS from a target cell of the network, wherein the measurement configuration message does not include Synchronization Signal Block (SSB) information for the target cell but further comprises an indication of whether the target cell transmits SSBs. The UE determines, based on at least the measurement configuration message, a time and frequency resource on which the CSI-RS of the target cell are to be transmitted and measures the CSI-RS of the target cell.

Abstract: Systems and methods for using a relay user equipment (UE) to transport data of interest received from a first remote UE to a second remote UE on a UE to UE relay within a wireless communication system are discussed herein. These methods may be performed at Layer 2 of a protocol stack of the wireless communication system. Data packets sent on the UE to UE relay may include an adaptation header including routing information (e.g., Layer 2 addresses, a bearer-specific index, etc.) for the UE to UE relay. An adaptation layer may accordingly be provided within Layer 2 to decode these adaptation headers. In some cases, a per-bearer approach may be used to map between individual direct bearers of a hop by hop path configuration of the UE to UE relay. Embodiments eschewing the adaptation header and instead using logical channel identifiers (LCIDs) to make routing indications are also described.

Abstract: A base station and a user equipment (UE) communicate the configure uplink communications in a multi-transmission and reception point (multi-TRP) configured network. The UE receives an indication of multiple sounding reference signal (SRS) resources that are to be used for uplink beam tracking, wherein each SRS resource is associated with different spatial relation information, transmits SRS using the associated spatial relation information, receives an indication that a user equipment (UE) is configured with one or more beam pairs, the one or more beam pairs configured by the network based on the SRS and transmits an uplink channel based on the indicated one or more beam pairs.

Abstract: A base station configures a Physical Downlink Control Channel (PDCCH) for transmission to one or more user equipments (UEs). The base station divides a component carrier (CC) bandwidth into a plurality of sub-bands, transmits a physical random access channel (PRACH) resource on at least one of the sub-bands and transmits a Type1-PDCCH CSS (Physical Downlink Control Channel Common Search Space) set on at least one of the sub-bands, wherein the Type1-PDCCH CSS set corresponds to the PRACH resource.

Abstract: A user equipment (UE) may transmit hybrid automatic repeat request (HARQ) feedback when part of a group of UEs. The UE receives a radio network temporary identifier (RNTI) associated with a group of UEs that includes the UE. The UE monitors for a signal from one of a cell on which the UE is currently camped or a cell to which the UE is currently connected that is scrambled by the RNTI and includes control information. The UE transmits HARQ feedback to the one of the currently camped cell or currently connected cell, the HARQ feedback associated with the signal and, when the signal is received, performs an operation in response to the control information.

Abstract: An evolved Node B (eNB) serves as a primary serving cell (PCell) providing a primary component carrier (PCC) in a licensed spectrum to a user equipment (UE) in a carrier aggregation (CA) scheme. A secondary component carrier (SCC) is provided in an unlicensed spectrum. The eNB monitors parameters of bandwidths in the unlicensed spectrum, when at least one of the parameters indicates a change in availability of a select one of the bandwidths, the eNB generates a control indicator defining the change in availability of the bandwidth and broadcasts the control indicator to the UE, wherein the control indicator affects a modification in a transceiver of the UE associated with the bandwidth.
