Abstract:
Methods, systems, and devices for wireless communications are described. A wireless device may identify a set of power configurations for a plurality of communications with at least one target device. The set of power configurations may be based at least in part on a type of signal, a type of channel, a parameter of the wireless device, a parameter of the target device, or a combination thereof. The wireless device may then determine a duplexing mode for the plurality of communications based at least in part on the set of power configurations. The duplexing mode may be, for example, a full duplex mode or a half-duplex mode. The wireless device may then transmit the plurality of communications to and/or receive the plurality of communications from the at least one target device according to the set of power configurations and the selected duplexing mode.
Abstract:
Embodiments provide a transceiver, wherein the transceiver is configured to transmit or receive data in at least one transmission time interval on certain allocated resource elements of a wireless communication system, wherein the transceiver is configured to at least partially blank a transmission time interval for a data block to be transmitted or received by the transmitter, wherein the transceiver is configured (a) to signal to another transceiver a transmission grant in a blanked part of the at least partially blanked transmission time interval or (b) to at least partially blank the transmission time interval based on a blanking pattern received from another transceiver.
Abstract:
There are provided methods and apparatus for controlling signaling of channel state information reference signals in a wireless communication system, including an apparatus for use in an eNB in a wireless communication network, the apparatus comprising control circuitry to generate first channel state information reference signals (CSI-RS), and map the generated CSI-RS as symbols of a self-contained subframe structure, and transmit circuitry coupled to the control circuitry, the transmit circuitry to transmit the mapped CSI-RS symbols.
Abstract:
Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for scheduling of multiple uplink transmissions in unlicensed spectrum. One embodiment involves receiving, at an eNB, a first uplink scheduling request from a UE, scheduling a plurality of uplink subframes on the unlicensed channel in response to the first uplink scheduling request, and initiating transmission of a first subframe to the first UE in response to the scheduling of the plurality of uplink subframes, wherein the first subframe comprises one or more downlink control indicators (DCIs) allocating the plurality of uplink subframes to the first UE.
Abstract:
The present invention relates to a method and apparatus for processing DMRS signal in a LTE protocol-based base station and an user equipment. According to one aspect of the present invention, the method comprises a method for processing DMRS signal in a LTE protocol-based base station, wherein before performing OFDMA modulation, the method further comprises: - performing pattern rotation processing with OCCs on subcarriers corresponding to available DMRS antenna ports so as to reduce power imbalance between OFDM symbols generated subsequently. The solution according to the present invention may eliminate or reduce the imbalance issue between OFDM symbols of the DMRS enhancement technology in the existing LTE protocol.

Abstract:
An apparatus of a base station, comprising: a controller to configure a first measurement gap pattern with a first measurement gap repetition period (MGRP) for a first receive (Rx) chain of a user equipment (UE); and configure a second measurement gap pattern with a second measurement gap repetition period (MGRP) for a second receive (Rx) chain of the UE, wherein the first MGRP is different from the second MGRP. The apparatus may configure the measurement gap patterns to support carrier aggregation and/or dual connectivity.
