Abstract:
Systems and method of embodiments herein operate to conserve battery power of user equipment (UE). Embodiments determine whether waking up a UE receiver would be beneficial and based on the determination, the UE either wakes up the receiver or returns to sleep. Embodiments determine whether to wake up the receiver by performing pre-wake up (PWU) operation which either wakes up the receiver in a low power mode or wakes up the UE's wake up receiver. It may be determined whether a wake up (WU) signal is received during a PWU stage. If a WU signal is received during the PWU stage the UE may perform a full wake up of the receiver. If a WU signal is not received the UE may return to idle mode. In embodiments, WU (Wake Up) DRX cycles are supplemented with a Full DRX (Discontinuous Reception) cycle.
Abstract:
Methods, systems, and devices for wireless communication are described. A wireless device may receive during an active duration, an indication of an opportunity to request uplink (UL) transmission. The wireless device may identify an opportunity to request UL transmission based at least in part on the indication. In some cases, the active duration may be a discontinuous transmission (DTX) configuration. The wireless device may then transmit on the UL resources during the opportunity to request UL transmission.
Abstract:
Methods, systems, and devices for wireless communication are described. A wireless device may receive data during an active duration of a discontinuous reception (DRX) configuration. The wireless device may be configured such that it identifies a transmission opportunity following the reception opportunity, so that it may transmit a response to the received data during the transmission opportunity. In another example, the wireless device may transmit data during an active duration of a discontinuous transmission (DTX) configuration. The device may be configured such that it identifies a reception opportunity following the DTX active duration, so that a response may be received during the reception opportunity. The presence of a transmission opportunity following a DRX active duration, or a reception opportunity following a DTX active duration may depend on the service type and priority of the data being communicated, and may be either semi-statically configured or dynamically signaled.
Abstract:
One or more scheduling grants may be received from a Node B related to a plurality of uplink MIMO streams. A determination may be made as to a primary transport power and a primary transport block size for a primary stream. A secondary transmit power and a secondary transport block size for a secondary stream may also be determined.
Abstract:
Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In some particular aspects, an E-TFC selection process for selecting a transport format combination for an uplink MIMO transmission may take certain steps in the case that a UE is power- or buffer-limited. For example, in a rank 2 transmission, non-scheduled data is allocated only to the primary stream. If the allocated non-scheduled data is less than the determined primary stream transport block size, scheduled data is allocated to the primary stream in an amount not to exceed the determined primary stream TBS. Finally, scheduled data is allocated to the secondary stream in an amount not to exceed the determined secondary stream TBS.
Abstract:
Techniques are described for wireless communication. A method of wireless communication includes receiving from an application server, at a network node of a wireless communication system, an indication of data to be delivered to at least one wireless device; determining a handling of the data; and transmitting at least one report relating to the handling of the data to the application server. Another method of wireless communication includes receiving from an application processor of a wireless device, at a modem of the wireless device, a request to receive at least one report on events monitored at the modem; and transmitting the at least one report to the application processor.
Abstract:
Wireless communication devices, systems, and methods related to power saving, including during connected mode operation and for extended reality (XR) data communications with or without discontinuous reception (DRX), are provided. For example, a method of wireless communication includes receiving, while in a connected mode, a configuration based on data traffic for the wireless communication device, the configuration indicating: a first zone associated with a first set of operating parameters for the wireless communication device; and a second zone associated with a second set of operating parameters for the wireless communication device, the second set of operating parameters being different than the first set of operating parameters; operating in the first zone with the first set of operating parameters to monitor for a first downlink communication signal; and operating in the second zone with the second set of operating parameters.
Abstract:
Techniques for wireless communications are described. Control information used to preschedule communication resources may be received and communications may be performed based on the control information using a prescheduling technique. A scheduling type used for the control information may be determined using configuration information, an indication included in the control information, or both. A wireless device that is prescheduled communication resources may not start or not restart an inactivity timer based on the received control information. Also, a wireless device that is prescheduled communication resources may not start a retransmission timer based on the received control information. Additionally, a wireless device that is prescheduled communication resources may also refrain from transmitting a scheduling request based on a duration until a next instance of prescheduled communication resources is expected to occur.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect radio link failure on a master cell group. Accordingly, the UE may determine a state of a secondary cell group (SCG). Additionally, the UE may initiate activation of the SCG based at least in part on the state of the SCG. For example, the activation of the SCG may be initiated based at least in part on the state being a deactivated state, a dormant state, or an enhanced dormant state. Accordingly, the UE may transmit master cell group (MCG) failure recovery information over the SCG and receive, on the SCG, MCG reconnection information. Numerous other aspects are provided.
Abstract:
This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for uplink traffic alignment and/or uplink traffic aggregation in wireless communication systems. A user equipment (UE) is configured with a mechanism for signaling uplink transmit opportunities to an application client using an application programming interface (API) disposed between a modem of the UE and the application client that enables uplink traffic generated by the application client to be aligned. The API includes semi-static parameters that may be used when a common timer is configured between the application client and the modem, and/or dynamic parameters that may be used when a common timer is not configured between the application client and the modem. The API may also include an extended signaling scheme that may include no-transmission (No-Tx) indications that indicate intervals during which no transmissions are allowed. These No-Tx parameters apply to the semi-static and/or dynamic signaling scheme.
