Abstract:
PROBLEM TO BE SOLVED: To provide techniques for supporting MIMO transmission with layer permutation.SOLUTION: Multiple codewords may be generated for transmission from multiple antennas (e.g., virtual antennas), with the number of codewords being less than the number of antennas. Each codeword is mapped to the multiple antennas. For rank 3, the first codeword may be mapped to one layer (or one antenna on each subcarrier), and the second codeword may be mapped to two layers (or two antennas on each subcarrier). For rank 4, each codeword may be mapped to two layers. A base CQI indicative of an average signal quality may be determined. A delta CQI indicative of improvement over the average signal quality may also be determined. Selection may be performed with different penalty factors for different ranks or number of codewords.
Abstract:
Systems and methods herein determine whether an uplink RACH request and/or an uplink autonomous message will be sent using Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing (DFT-S-OFDM), Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM), or another waveform. Other aspects, embodiments, and features are also claimed and described.

Abstract:
Techniques are described for wireless communication by a first user equipment (UE) in communication with a base station. In one embodiment, a of method wireless communication by a first user equipment (UE) in communication with a base station comprises receiving, at the first UE, a downlink grant that assigns resources for transmission to at least the first UE; monitoring, at the first UE, for a control signal indicating that a portion of the resources assigned by the downlink grant is to be preempted for transmission to a second UE; determining, at the first UE based at least in part on the monitoring, whether to process the portion of the resources assigned by the downlink grant indicated to be preempted; and discontinuing processing, at the first UE based at least in part on the determining, of the portion of the resources assigned by the downlink grant indicated to be preempted. 520 525 530 530 540 550 560 ese PDSCH PDSCH PDSCH PDSCH PDSCH PUSCH UEl UEl UEl UE2 UE3 PUCCH
Abstract:
Methods, systems, and devices for wireless communication are described that may perform dual stage channel interleaving in which code blocks are interleaved at the code block level and at a symbol level. The interleaved code block data may provide time diversity for the code block data, and the interleaved symbol data may provide frequency diversity for the code block data, thus helping to mitigate narrowband and/or bursty interference. The interleaving within the code block and interleaving within the symbols, in some examples, may allow pipelined implementation of decoding of the code blocks at the receiver, for faster processing. In some cases, systematic data and parity data may be interleaved within the code block data to provide a uniform distribution of the systematic data in time within the code block.
Abstract:
Various aspects of the disclosure relate to event triggers for independent links. For example, an event trigger may be based on measurements from multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, an event trigger may be based on aggregated measurements from multiple links.
Abstract:
Channel reservation systems and methods are disclosed herein, which schedule transmissions on a shared radio medium that is shared by a plurality of licensed network operators. In embodiments, priority access is pre-assigned to the network and the method determines whether to send a transmission based at least on the transmitter's priority class as compared to another transmitter's priority class and to which transmitter the time slot of a signal is dedicated. In embodiments, priority access may not be preassigned to the network and pre-grants may be used in conjunction with CR-Ts and CR-Rs to determine whether a transmitter transmits.
