Abstract:
A user equipment (UE) may include a wireless local area network (WLAN) transceiver chain that is used for both WLAN communications and communications on another wireless radio access technology (RAT), such as wireless wide area network (WWAN) communications. The communications may be synchronized, and then at least a portion of the WLAN transceiver chain may be scheduled for time-division multiplexed (TDM) communications, wherein a first set of TDM intervals are for communications using the other RAT, and a second set of TDM intervals are for communications using the WLAN.
Abstract:
A user equipment (UE) may determine a capability of the UE to support multiple subscriber identity modules (SIMs). The multiple SIMs may enable the UE to communicate with multiple network nodes. The UE may notify at least one network node of the multiple network nodes of the multiple SIM capability of the UE.
Abstract:
An amount of time is determined for a data packet at a medium access control (MAC) layer of a first apparatus to reach an application layer of a second apparatus. A MAC layer lifetime limit of the data packet is set based on the determined amount of time, and the data packet is discarded when the MAC layer lifetime limit is reached. The MAC layer lifetime limit of the data packet includes a duration of time during which the data packet is suitable for transmission. The MAC layer lifetime limit of the data packet may be different from a MAC layer lifetime limit of another data packet associated with an access category that is the same as the access category with which the data packet is associated. Various other aspects are provided.
Abstract:
Methods, systems, and devices are described for adjusting at least one channel parameter based on accessed historical channel information associated with mobility patterns of a mobile device. In some examples, a mobile device or a base station may access historical channel information associated with mobility patterns of the mobile device or another mobile device. The mobility patterns may include information relative to a particular time and location of a mobile device, a previously traveled route by a mobile device, etc. Based on the historical channel information associated with the mobility patterns, the mobile device or the base station may adjust a channel parameter to improve communication performance across the particular channel.
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling from a base station that identifies a set of channel monitoring parameters associated with monitoring an unlicensed frequency spectrum band. The set of channel monitoring parameters may include at least one of a length of a channel monitoring window, a periodicity of the channel monitoring window, a carrier or a bandwidth part of the channel monitoring window, or a combination thereof. The UE may identify a termination of a transmission opportunity in the unlicensed frequency spectrum band, and monitor the unlicensed frequency spectrum band following the termination of the transmission opportunity using the set of channel monitoring parameters.
Abstract:
Methods, systems, and devices are described for optimizing handover or cell reselection of a mobile device based on historical information associated with mobility patterns of the mobile device. The mobile device may autonomously determine when a resource for the mobile device may be released based on the historical information. The mobile device may transmit a message to a serving cell indicating when the resource may be released and perform a handover or cell reselection procedure of the mobile device to the target cell. The serving cell may release the resource based on the indication received in the message.
Abstract:
Methods, systems, and devices are described for predicting a current random access transmission power detectable by a base station based on historical transmission power information. In one aspect, a mobile device may access a historical transmission power associated with a current state of the mobile device, with the historical transmission power based on mobility patterns of the mobile device. Based at least in part on the accessed historical transmission power, the mobile device may predict a current random access transmission power of the mobile device, where the predicted current random access transmission power is configured to elicit a random access response from a base station. In one aspect, the techniques described herein may reduce a number of power ramp steps taken by the mobile device during a random access procedure, reduce interference from the mobile device during the random access procedure, or both based on the predicted current random access transmission power.
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a signal to a base station indicating a UE capability configuration. The EE may receive, over an unlicensed radio frequency spectrum band, a wakeup signal during a monitoring period, the wakeup signal indicating that wireless communications are to be performed between the EE and the base station during an active time period. The EE may identify a guard time period upon receiving the wakeup signal, wherein the guard time period is based at least in part on the EE capability configuration. The EE may perform, after an expiration of the guard time period, the wireless communications with the base station during the active time period.
Abstract:
A network node may receive a notification of a capability of a user equipment (UE) to support multiple subscriber identity modules (SIMs). The multiple SIMs may enable the UE to communicate with multiple network nodes. The network node may modify a communication parameter of the network node based on the notification.
Abstract:
A user equipment (UE) may receive a wireless wide area network (WWAN) signal on a first antenna. The UE may process the WWAN signal with a portion of a WWAN receive chain of a WWAN module of the UE. The WWAN signal may be routed from the WWAN receive chain to a wireless local area network (WLAN) receive chain of a WLAN module of the UE. The UE may then process the WWAN signal with a portion of the WLAN receive chain.
