Abstract:
A user equipment (UE) may manage coexistence between multiple radio access technologies (RATs) utilized by the UE to allow a first RAT to be active during times when communications of a second RAT of the UE are inactive. In some instances, the UE may indicate discontinuous reception (DRX) operation of the UE to allow for time-division multiplexed (TDM) operation between the first RAT and the second RAT. The UE may set a hybrid automatic repeat request (HARQ) configuration to allow for a HARQ retransmission of a packet of the first RAT, originally received in a first DRX cycle, during a second DRX cycle.
Abstract:
A system capacity improvement is achieved by dynamically selecting a particular antenna mode of operation from the multiple radio access technology modes. In some implementations, the system capacity improvement is achieved by dynamically generating an indication of a user equipment (UE) antenna capability during a communication connection. The UE's indication of its antenna capability is dynamic and/or is subject to change throughout the duration of the communication connection. The indication may be sent to a base station.
Abstract:
Techniques for structured channel rasters for unlicensed spectrum are described. In an aspect, a first channel raster is identified, where the first channel raster is determined from a set of carrier frequencies and is used over an unlicensed or shared spectrum for a wireless wide area network (WWAN). The first channel raster is aligned with a second channel raster that is used over the unlicensed spectrum for a wireless local area network (WLAN). A frequency scanning may be performed by a user equipment (UE) or a network entity over the unlicensed spectrum for the WWAN using the first channel raster. In an aspect, the first channel raster is used over the unlicensed spectrum for the WWAN supported by the user equipment (UE) or the network entity.
Abstract:
Methods, systems, and devices for wireless communication are described for monitoring interference level to selectively control usage of a contention-based protocol. In an example, a wireless device may transmit, while operating in a non-contention-based mode for a wireless link with a second wireless device, a first beamformed data transmission to the second wireless device over a shared channel. The wireless device may determine that an interference level condition is satisfied for the shared channel and transition from operating in the non-contention-based mode to operating in a contention-based mode for the wireless link based at least in part on the interference level condition being satisfied. The wireless device may perform a contention-based protocol, while operating in the contention-based mode for the wireless link with the second wireless device, prior to transmission of a second beamformed data transmission to the second wireless device over the shared channel.
Abstract:
Wireless communication apparatus and methods related to dynamic TDD are described. In aspects, a method of wireless communication over a shared medium may include, receiving, from a base station, control information in a first portion of a transmission opportunity (TXOP), wherein the control information indicates a configuration for triggering a communication of at least one shared medium reservation signal associated with one or more remaining portions of the TXOP; and in response to receiving the control information in the first portion of the TXOP, monitoring for or transmitting the at least one shared medium reservation signal, based on the configuration.
Abstract:
Techniques for managing preamble transmission and processing on a shared communication medium are disclosed. An access point or an access terminal, for example, may generate a preamble for silencing communication on a communication medium with respect to an upcoming data transmission, configure the preamble to identify one or more target devices for the silencing, and transmit the preamble over the communication medium in advance of the data transmission. Conversely, the access point or the access terminal may receive a preamble (as a receiving device) over a communication medium, identify one or more target devices for silencing communication on the communication medium with respect to an upcoming data transmission based on the preamble, and selectively silence communication over the communication medium based on itself (as the receiving device) being among the one or more target devices.
Abstract:
The present disclosure relates generally to uplink procedures on a shared communication medium. In an aspect, an access terminal receives a downlink subframe from an access point on the shared communication medium and, in response to receiving the downlink subframe, transmits uplink control information (UCI) for the downlink subframe on a first uplink subframe of a first UCI channel of a plurality of UCI channels.
Abstract:
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.
Abstract:
Described herein are techniques for reducing efficient LTE operation in the unlicensed band. For example, the technique may involve establishing a connection with a primary component carrier on the licensed communication band or the unlicensed communication band. The technique may also involve determining at least one metric associated with a constraint on a transmissions channel of the unlicensed communication band. The technique may also involve sending the at least one metric to the primary component carrier. The technique may also involve receiving a message for one of switching on or switching off a secondary component carrier (SCC) for transmissions on the unlicensed communication band in response to sending the at least one metric.
Abstract:
Techniques for channel configuration on a shared communication medium are disclosed. An access point may select a set of resource elements to carry an uplink control channel and transmit a configuration message including one or more configuration parameters associated with the selected set of resource elements to one or more access terminals. The access point may then receive uplink control signaling from the one or more access terminals via the selected set of resource elements. An access terminal may receive a configuration message including one or more configuration parameters for an uplink control channel from an access point and determine a set of resource elements configured to carry the uplink control channel based on the configuration message. The access terminal may then transmit uplink control signaling to the access point via the determined set of resource elements.
