Abstract: Systems and methods are provided to improve UE power management and support multiple-PDCCH based multi-TRP or multi-antenna panel transmission with intra-cell (same cell ID) and inter-cell (different Cell IDs). The methods involve configuring CORESETs and associated search space sets. A configured search space set can then be activated implicitly activating the associated CORESET, or a configured CORESET can be activated implicitly activating the associated search space sets. Alternatively, CORESET-search space set links are configured, and then activated. Multiple different overall configurations, each having different CORESET, search space set configurations may be provided and selected between.

Abstract: A reference signaling scheme is provided that is based on the use of a Zadoff Chu sequence with cyclic repetition, optionally code division multiplexing precoding, together with frequency domain spectral shaping (FDSS). A specific pulse shape design for the FDSS part of the reference signal scheme in some embodiments involves the use of a raised cosine pulse raised to the power of β. The new solution for generating reference signals has a Low peak average power ratio that matches the PAPR of SC-OQAM, good channel estimation performance, and the ability to implement CDM in the frequency domain to increase multiplexing gain.

Abstract: A user equipment (UE) receives control signaling in a scheduling bandwidth part (BWP). The control signaling indicates switching from a first active BWP to a second active BWP or switching from a first active BWP pair to a second active BWP pair for the UE. The control signaling aligns with a time unit boundary, such as a slot boundary, that is associated with the scheduling BWP. In the event that a scheduled BWP for a UE has a different numerology than a scheduling BWP that is currently active for the UE, the UE could switch from the scheduling BWP to the scheduled BWP based on a control signaling monitoring periodicity of the scheduled BWP.

Abstract: Systems and methods are provided in which uplink transmission of pilot uses time-frequency resources that overlap with time-resources for the uplink transmission of data, by the same UE or different UEs. This can result in a decrease in pilot overhead, or if longer pilot sequences are used, can result in a decrease in collision probability. In a group-based approach, UEs are organized into groups, and each group is allocated the same resources for pilot and data.

Abstract: Systems and methods for detecting potentially active user equipment (UE) in a network are provided. A set of potentially active UEs is detected using an iterative method. In a first iteration UE detection is performed using compressed sensing (CS) based on first pilot sequences to detect a first set of potentially active UEs. Channel estimation is then performed for the first set of potentially active UEs. In subsequent iterations, UE detection is performed using CS to detect another set, typically reduced in size, of potentially active UEs using results of the channel estimation from the previous iteration. Channel estimation is then again performed for the new set of potentially active UEs. After the last iteration, the set of potentially active UEs detected in the last iteration is output as the determined set of potentially active UEs along with channel estimates for the set of potentially active UEs determined in last iteration.

Abstract: Control signaling mechanisms are provided to support data transmissions to or from a user equipment (UE) in an inactive state. In some embodiments, a UE in an inactive state receives DCI including: a cyclic redundancy check (CRC) scrambled by a radio network temporary identifier (RNTI) that is specific to a group of UEs, the group of UEs including the UE; and a resource assignment for a data transmission to the UE. The data transmission is then received on a physical shared channel. In further embodiments, a UE in an inactive state receives DCI including: a CRC scrambled by a paging RNTI; and a resource assignment for a paging message to the UE. A data transmission is received by the UE in the paging message or in a further transmission that is scheduled by the paging message.

Abstract: Systems and methods for transmitting uplink control information, for example ACK/NACK, while in RRC_inactive state, are provided. Uplink control information is transmitted while in RRC_INACTIVE state by transmitting a sequence from a set of possible sequences to convey the uplink control information, the transmitted sequence associated with a value of the uplink control information. The sequence is asynchronously transmitted. Signalling may be used to configure a transmission resource within which to transmit the sequence, wherein the transmission resource has a time duration that is longer than a time duration to transmit the sequence. This has the effect of introducing a gap following sequence transmission that can ensure the sequence transmission does not interfere with a data transmission.

Abstract: Control signaling in multiple access communication systems, including apparatus and methods, is disclosed. Multiple access to a wireless communication link is based on power modulation division. Modulation information, capacity information, resource scheduling information, and resource assignment information is determined by a base station. Information is transmitted to user equipment devices in a common control channel in accordance with the determined modulation information, capacity information and resource scheduling information. Information is also transmitted to supporting user equipment, which supports the power modulation division multiple access, in a user equipment-specific control channel in accordance with the determined resource assignment information.

Abstract: Some aspects of the present disclosure introduce a new downlink (DL) bandwidth part (BWP) and a new uplink (UL) BWP for communication in the RRC_INACTIVE state. In addition, aspects of the disclosure also provide for configuring generic parameters of the BWP, which include, but not limited to, frequency location, bandwidth, subcarrier spacing (SCS), and cyclic prefix (CP). Some aspects of the present disclosure may support a reinterpretation of generic parameters of a BWP, for example which may be configured for the RRC_CONNECTED state, to be used in the RRC_INACTIVE state. Some aspects of the present disclosure are directed to implicit DL BWP switching in the RRC_INACTIVE state where no BWP identifier (ID) indication is needed as part of the switching mechanism.
