Abstract:
A wireless apparatus including a machine-to-machine (M2M) device. The M2M device has an applications processing element, RF transceive elements, and a deep sleep controller. The applications processing element executes one or more functions corresponding to an M2M processing environment, and directs the transmission and reception of radio frequency (RF) messages. The RF transceive elements are operationally coupled to the applications processing elements and transmit and receive the RF messages over the one or more wireless communications links. The deep sleep controller is coupled to the applications processing element and the RF transceive elements, and directs the applications processing element to request a sleep time from a corresponding base station, and causes the M2M device to enter a deep sleep mode upon acceptance of the sleep time by the corresponding base station, where the deep sleep mode is entered by removing power from the RF transceive elements.
Abstract:
A method for mobile station accessing to a base station in a wireless communication system that uses selective acknowledgement mechanism, comprising: transmitting, an access probe from the mobile station to the base station; receiving, a message from the base station, wherein the message indicates parts of the plurality of data frames are not decoded by the base station; passing, an instruction from a MAC layer to a PHY layer of the mobile station, wherein the instruction is used to send a selective acknowledgement header; sending, the parts of data frames that are not decoded by the base station from the MAC layer to the PHY layer according to the message; and retransmitting the parts of the plurality of data frames.
Abstract:
Communication system and method of data communication are provided. The method of data communication for a MAC layer includes initiating an access attempt; transmitting, by a mobile station, a probe to a base station (BS), wherein the probe includes header information and data frames; decoding the header information and the data frames; generating, by the BS, a SACK message; and transmitting the SACK message to the MS.
Abstract:
Systems, apparatuses, methods, and computer-readable media are directed to techniques for codebook support for different antenna structures, such as a user equipment (UE) with a non-uniform antenna array (e.g. with different distances between antenna elements) and/or multiple antenna panels. Embodiments further provide techniques for enhanced operation in full power mode 2. For example, embodiments provide techniques for antenna virtualization to form virtual antenna ports from subsets of transmit antennas of the UE (e.g., from eight transmit antennas to two, four, or six virtual antenna ports). Other embodiments may be described and claimed.
Abstract:
Methods, systems, and storage media are described for beam management for higher-frequency systems, such as, for example, those above 52.6 GHz. Other embodiments may be described and/or claimed.
Abstract:
A generation node B (gNB) configured for aperiodic channel state information reference signal (CSI-RS) triggering and transmission may encode signalling for transmission to a user equipment (UE). The signalling to indicate an aperiodic Triggering Offset (aperiodicTriggeringOffset). The aperiodic Triggering Offset may comprise a slot offset. The gNB may encode a downlink control information (DCI) for transmission that may trigger transmission of a CSI-RS in one or more aperiodic CSI-RS resource set(s) (i.e., in one or more slots (n)). The DCI triggers transmission of the aperiodic CSI-RS within a triggered slot with the slot offset (i.e., the aperiodicTriggeringOffset). The gNB may transmit the CSI-RS in resource elements of the triggered slot in accordance with the slot offset, when CSI-RS resources are available in the slot at the slot offset. The gNB may postpone transmission of the aperiodically triggered CSI-RS to a first available downlink slot when the CSI-RS resources are not available in the triggered slot at the slot offset.
Abstract:
Bandwidth part (BWP) switching for aperiodic sounding reference signal (SRS) transmissions is triggered via a downlink control information (DCI) format that does not include scheduling information. When a DCI format does not schedule a physical uplink shared channel (PUSCH) and does not include a channel state information (CSI) request, the UE may interpret one or more fields of the DCI format for the aperiodic SRS transmission.
Abstract:
A computer-readable storage medium stores instructions to configure a UE for a power control procedure in a 5G NR and beyond wireless network. The instructions cause the UE to perform operations including decoding RRC signaling received from a base station. The RRC signaling includes one or more open-loop power control parameters. A reference signal received power (RSRP) is determined. The RSRP is associated with a reference signal received from the base station using a receive beam. A path loss associated with the receive beam is determined based on the RSRP. A transmission (Tx) power is determined using the one or more open-loop power control parameters and the path loss. The Tx power is adjusted based on a power threshold shared between at least two antenna panels of a plurality of antenna panels. Uplink data is encoded for transmission to the base station according to the adjusted Tx power.
