摘要:
A pair of slide cutting shears that have identical cutting angles of approximately 53 degrees on the thumb and finger blades, and where the thumb blade has approximately only 40% of the top end of the blade sharpened and the remaining section of the working blade is radiused and cannot cut. The shears have a four finger grip, and adjustable bump stop and a tightenable pivot pin assembly to draw the blades closer.

Certain aspects of the present disclosure generally relate to wireless communication. More particularly, certain aspects of the present disclosure relate to early termination of a downlink channel repetition transmission, early termination of an uplink channel repetition, and/or determination of a plurality of beams for a repetition transmission. Numerous other aspects are provided.
摘要:
Signaling design for interlaced frequency divisional multiplex (IFDM) demodulation reference signals (DMRS) is discussed in which a dynamic indication is provided to a user equipment (UE) from a serving base station that allows the UE to configure transmission of DMRS according to either a single carrier frequency divisional multiplex (SC-FDM) or IFDM configurations, as indicated by the dynamic indication. The IFDM configuration may be applicable to either regular uplink subframes or within the uplink portion of special subframes. In some aspects, power boosting may be provided for the DMRS in order to equalize transmit power between decimated DMRS transmitted with the data tones. Additional aspects may also provide for different offsets to be used depending on the type of uplink control signal transmitted.

Methods, systems, and devices for encoding and decoding are described. To encode a vector, an encoder allocates information bits of the vector to channel instances of a channel that are separated into groups. The groups may vary in size and allocation of the information bits is based on a base sequence of a given length. During decoding, a decoder assigns different bit types to channels instances by dividing a codeword into a plurality of groups and assigning bit types to channel instances of the plurality of groups using the base sequence.

The described techniques relate to improved methods, systems, devices, or apparatuses that support communication schemes for small cyclic delay diversity (SCDD) reference signals. A base station may transmit a control message comprising at least one channel state information (CSI) configuration parameter to a user equipment (UE). The UE may identify a time offset between a plurality of virtual antennas of the base station based at least in part on the CSI configuration parameter. The UE may perform measurements of a plurality of CSI reference signals (CSI-RSs) transmitted by the base station and associated with the virtual antennas. The UE may transmit a feedback message based at least in part on the determined time offset and the measurements of the CSI-RSs.

Methods, systems, and devices are described for interference mitigation between neighboring cells through the use of cell clusters and virtual logical cell clusters. Cells may be added to a cell cluster with a first cell when a level of interference coupling between the first cell and one or more neighboring cells exceeds a first threshold. One or more other cells may be added to a virtual logical cell cluster with the first cell when the level of interference coupling is between a second threshold and the first threshold, the second threshold being less than the first threshold. Interference mitigation between cells of cell clusters and/or virtual logical cell clusters may be performed. Interference mitigation may be accomplished through, for example, coordination of TDD uplink-downlink (UL-DL) configurations for cell clusters and scheduling-dependent interference management (SDIM) for virtual logical cell clusters.

A method for improved random access procedures by a UE is provided. The method comprises: measuring a common CSI-RS; selecting a best horizontal/vertical beam from a set of fixed beams; determining a preamble mapped to the selected horizontal/vertical beam; transmitting the preamble; and receiving a random access response.
摘要:
Methods, systems, and devices are described for discontinuous transmission and/or discontinuous reception in time division duplex (TDD) systems that may have data transmission formats dynamically reconfigured. An initial uplink-downlink (UL-DL) configuration for TDD communication between an eNB and user equipment (UE) may be established. This initial UL-DL configuration may be reconfigured to a different UL-DL configuration for one or more UEs in communication with the eNB. When a UE switches to discontinuous reception (DRX) mode, it may monitor control information from the eNB during DRX on periods, a frequency of the DRX on periods based on a reference UL-DL configuration irrespective of any reconfiguration of UL-DL configuration for a particular UE. In some aspects, a UE that is operating in a UL-DL reconfiguration mode may, upon entering DRX mode, autonomously discontinue operating in the UL-DL re-configuration mode.

First correction information is received from a system module, the correction information determined from first calibration of the base station Signals are received at a radio frequency module from at least one antenna of the base station Second correction information is determined on the basis of the received signals and the first correction information.
摘要:
According to an example embodiment, a method may include determining, by a first wireless node in a wireless network, a number N of resource blocks available for transmitting data within a cell, the N resource blocks each including V resource block orthogonal frequency division multiplexing (OFDM) symbols, the V resource block OFDM symbols each including U resource block subcarriers. The method may also include mapping the N resource blocks into N subchannels based on a permutation formula, the permutation formula assigning, based on permutation parameters including the number N and a random or pseudorandom variable, U subchannel subcarriers for each of V subchannel OFDM symbols to each of the N subchannels and thereby allocating a subchannel index for each of the N subchannels. The method may also include sending a message to a second wireless node indicating the permutation parameters and the allocated subchannel index of at least one of the N subchannels for communication between the first wireless node and the second wireless node.
