Abstract: Methods, systems, and devices for wireless communications are described for beamformed communications. In some aspects, when using beamformed communications, a first communications node and a second communications node may establish a beam pair link using a first beam. The first communications node may use a first set of beamforming weights at each antenna element of a set of antenna elements for transmissions of the first beam. After the beam pair is established, the first communications node may transmit multiple sounding signals using different subsets of the first set of antenna elements. A second communications node may measure the multiple sounding signals and use the measurements in scheduling one or more transmissions at the first communications node (e.g., to determine a modulation and coding scheme or coding rate), using one or more of the subsets of antenna elements.

In response to not receiving, within a first predetermined time, the first acknowledgement response, decreasing the size of the first sending window based on a second proportion; and in response to determining that the size of the first sending window is greater than or equal to a first threshold, sending a second data packet to a second receiving window of the second network device by using a second sending window.

Abstract: A user equipment (UE) transmits concurrent channel state information (CSI) processing capability information to a base station. The capability information can take various forms, and is intended to constrain the base station in the types of CSI requests that can be made to the UE. For example, the UE may indicate different CSI processing capabilities for intra-CC and inter-CC cases and/or for different codebook types. The UE may also specify supported combinations of codebook types for concurrent CSI reporting. The UE may also specify maximum resources or weighting factors for different codebook types. The UE may further restrict the rank information it provides and use a priority rule for “dropping” CSI report data due to payload size restrictions. The base station may direct, or the UE may implement, improved utilization of CSI resources that are shared for multiple concurrent CSI reports. Minimum time requirements for CSI reporting may also be relaxed.

Abstract: A user equipment terminal (UE) in a wireless network calculates a measurement period for measuring the signal-to-interference-plus-noise ratio (SINR) for a serving cell within a frequency range. The calculation is based on a channel measurement resource (CMR) and an interference measurement resource (IMR). The calculation includes evaluation of a sharing factor P, which is a maximum of PCMR of the CMR and PIMR of the IMR. The PCMR and the PIMR are evaluated, at least in part, based on periodicity of the CMR and the IMR in relation to other periodic measurements performed by the UE. The UE performs a channel measurement and an interference measurement using the CMR and the IMR, respectively, over the measurement period. The UE calculates the SINR based on the channel measurement and the interference measurement; and transmits an SINR measurement report indicating the calculated SINR to a base station.
