摘要： Methods and devices for a base station acting as a primary cell to perform dual spectrum sharing (DSS) with a first user equipment device (UE) over a 5G NR connection and a second UE over an LTE connection. The first UE establishes the 5G NR connection with the primary cell and one or more secondary cells. One of the secondary cells is configured in the 5G NR connection to provide downlink control information to the UE for the primary cell, to avoid collisions by the primary cell with LTE control transmissions.

摘要： Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A serving base station may configure a coverage-limited UE with parameters for the UE to operate in a coverage enhancement mode through RRC signaling, DCI, or RAR grant. The UE may use the configuration parameters to determine whether to enter into the coverage enhancement mode when connecting and communicating with the serving base station. The configuration parameters may configure the UE to exploit both time diversity and frequency diversity to extend and enhance coverage when receiving the PDSCH and PDCCH channels, when transmitting the PUSCH and PUCCH channel, and when transmitting PUSCH Msg3 during random access. Advantageously, the base station may flexibly and dynamically configure the UE with coverage enhancement parameters to extend the coverage of the UE using time diversity and frequency diversity gains as the UE moves around.

摘要： 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.

摘要： Methods, circuitries, and systems are disclosed for configuring multiple PDSCH/PUSCH transmission with repetition of each transmission. In one example, a method includes receiving, from a base station, control information that indicates i) time domain resources for communication of at least two physical downlink shared channel (PDSCH) or at least two physical uplink shared channel (PUSCH) transmissions and ii) at least one repetition number indicating a number of times each of the at least two PDSCH/PUSCH transmissions is repeated. The method includes configuring operation to receive the at least two PDSCH transmissions or to transmit the at least two PUSCH transmissions based on the time domain resources and repetition number.

摘要： 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.

摘要： Reporting capabilities regarding Cross Carrier Scheduling (CCS) with different Sub-Carrier Spacing (SCS) may include generating a message to send to a base station. The message may comprise an indication of a user equipment's (UE's) capability for CCS with different SCS. Based on the UE's capability for CCS with different SCS, a number of unicast downlink control information (DCI) per physical downlink control channel (PDCCH) monitoring occasion per span may be processed to determine scheduled resources for downlink (DL) and uplink (UL) signaling or channels. The DL and UL signaling or channels may be processed using the scheduled resources.

摘要： A user equipment (UE) and a network agree on the use of a hybrid automatic repeat request (HARQ) codebook. The UE receives a plurality of downlink control information (DCI) transmissions during a corresponding plurality of physical downlink control channel (PDCCH) monitoring occasions from the base station, wherein each DCI transmission schedules multiple physical downlink shared channel (PDSCH) transmissions on a corresponding one of a plurality of component carriers (CCs), receives a time domain resource allocation (TDRA) table configuration from the base station, determines a maximum number of PDSCH transmissions per CC based on the TDRA table configuration, groups the plurality of CCs together and determines a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) codebook size based on a number of the multiple PDSCH transmissions, the maximum number of PDSCH transmissions, and a resulting ACK or negative acknowledgement (NACK) for each of the multiple PDSCH transmissions.
