摘要： Techniques for co-existence between wireless Radio Access Technologies (RATs) are disclosed. During an active period of a Discontinuous Transmission (DTX) communication pattern, a first signal may be transmitted during a first subframe and a second signal may be transmitted during a second subframe, while during an inactive period the first signal may be transmitted during the first subframe and the second signal may be omitted during the second subframe. Retransmission of one or more packets may take place over a subset of less than all retransmission opportunities based on the DTX communication pattern. A Secondary Cell (SCell) may be reconfigured as the Primary Cell (PCell) and the PCell may be reconfigured as the SCell for one or more access terminals based on a load balancing condition or a channel selection condition.

摘要： Certain aspects of the present disclosure relate to communication systems, and more particularly, to a control resource set (coreset) for transmitting physical downlink control channels using a single-carrier waveform in communications systems operating according to new radio (NR) technologies. In an exemplary method, a base station may determine a first control resource set (coreset) of time and frequency resources within a control region of system bandwidth, to transmit a physical downlink control channel (PDCCH) to a user equipment (UE) and transmit the PDCCH to the UE as a single-carrier waveform via the first coreset of time and frequency resources.

摘要： In an embodiment, an access point executes a Clear Channel Assessment (CCA) protocol to determine whether to begin transmission within a DRS Measurement Timing Configuration (DMTC) window. The access point transmits, based on a result of the execution, a multi-subframe DRS within the DMTC window, the multi-subframe DRS including a plurality of DRS subframes that each includes a plurality of symbols.

摘要： Certain aspects of the present disclosure relate to methods and apparatus for optimizing millimeter wave beam-searching. In certain aspects, a method for use by a wireless communications device includes determining a usage scenario of the wireless device based on input performing a beam search to maintain or establish a communication link with one or more other wireless devices, wherein one or more beams are prioritized or de-prioritized during the beam search based on the usage scenario.

摘要： In an embodiment, an AT monitors a DMTC window of a shared communication medium while refraining from performing any AUL transmissions. The AT selectively transmits one or more AUL transmissions based on the monitoring (e.g., in response to DRS detection, either in one or more subframes of the DMTC window or outside of the DMTC window). In a further embodiment, the AT establishes different LBT contention windows for use during and outside of POWs and/or DMTC windows. In a further embodiment, the AT receives an AUL disable signal instructing the AT to disable AUL transmissions, and the AT refrains from performing one or more AUL transmissions on the shared communication medium in response to the AUL disable signal.

摘要： Techniques for managing channel reservation on a shared communication medium are disclosed. An access point or an access terminal contending for access to a communication medium shared between a first Radio Access Technology (RAT) and a second RAT, for example, may encode a first portion of a channel reservation message defined by the first RAT with a transmission opportunity duration associated with the second RAT and also encode a second portion of the channel reservation message with the transmission opportunity duration. The access point or the access terminal may then transmit, over the communication medium, the channel reservation message including the first and second portions to reserve the communication medium based on the contending.

摘要： Techniques for co-existence on a shared communication medium are disclosed. To foster co-existence, operation of a first Radio Access Technology (RAT) may be cycled between active periods and inactive periods of transmission, on a communication medium shared with a second RAT, in accordance with a Discontinuous Transmission (DTX) communication pattern. An identifier may be selected for association with the first RAT. A channel reservation message associated with the second RAT may then be transmitted, over the communication medium, to reserve the communication medium for one of the active periods, the channel reservation message including the identifier.

摘要： Apparatus and methods of wireless communications are described for determining one or more bands (e.g., guard bands in wireless local area networks (WLANs)) in unused portions of an unlicensed spectrum, positioning one or more carriers for cellular communication (e.g., long term evolution (LTE) or LTE advanced communication) in the one or more bands, and performing the cellular communication over the unlicensed spectrum using the one or more carriers. In some non-limiting example aspects, the cellular communication may be in a standalone mode and the one or more carriers may include a primary component carrier (PCC) that is positioned in a Wi-Fi guard band. In these non-limiting example aspects, the apparatus and methods may further include allocating one or more secondary component carriers (SCCs) in Wi-Fi guard bands or in Wi-Fi channels, where the one or more SCCs are opportunistically tuned or turned ON/OFF based on cell loading or backhaul constraints.

摘要： An eNB may retransmit packets according to a hybrid automatic repeat request using superposition coding. In one instance, the eNB receives a negative-acknowledgement of an initially transmitted packet and retransmits at least one packet according to hybrid automatic repeat request using superposition coding in response to the negative-acknowledgement. The eNB also retransmits packets according to variable block length retransmission. In this instance, the eNB receives a negative-acknowledgement of an initially transmitted fixed block length packet and retransmits a variable block length packet in response to the negative-acknowledgement
