摘要： A base station may operate in a context where the propagation delay between the base station and user equipment (UE) devices is large. The base station configures UE devices with a common delay. The base station receives a random access preamble from a UE device. The base station determines a time slot in which the random access preamble was transmitted, based on a configured correspondence between allowable time slots and subsets of an available set of preambles. The base station computes a Random Access Radio Network Temporary Identifier (RA-RNTI) based on parameter values including an index of the determined time slot. The base station employs the computed RA-RNTI to address a random access response for the UE device.

摘要： A user equipment (UE) device may perform random access to a base station in the context where propagation delay between the base station and the UE device is large. The UE device randomly selects a random access preamble from an available set of preambles. The UE device selects a time slot for transmission of the random access preamble based on a configured correspondence between allowable time slots and subsets of the available set. The UE device transmits the random access preamble to a base station in the selected time slot, with timing advance to compensate for a common delay. Thus, the base station, knowing the configured correspondence, is able to determine the time slot in which the random access preamble was transmitted. The UE device receives a random access response that has been addressed with a Random Access Radio Network Temporary Identifier (RA-RNTI).

摘要： This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A user equipment device (UE) may transmit to a base station a random access initiation message, having a characteristic that is configured to indicate to the base station a requested size of a subsequent uplink grant to be provided by the base station for transmission of uplink data by the UE. For example, the characteristic may include a predetermined preamble included in the random access initiation message, such that a requested grant size is indicated by which preamble the UE selects from a plurality of possible preambles. As another example, the characteristic may include which RACH occasion is selected by the UE to transmit the random access initiation message. In response, the base station may allocate resources for use by the UE based on the characteristic.

摘要： This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A user equipment device (UE) may transmit to a base station (BS) a first buffer status report (BSR) indicating an amount of uplink data buffered by the UE for transmission to the BS, and may subsequently transmit to the BS a first BSR update message indicating that an additional amount of uplink data has been buffered by the UE subsequent to transmission of the first BSR. The first BSR update message may be transmitted prior to expiration of a timer authorizing transmission of a second BSR following the first BSR. The UE may receive from the BS an uplink grant allocating resources for transmission of at least a portion of the uplink data buffered by the UE. The uplink grant may have a size based on the first BSR and the first BSR update message.

摘要： A user equipment device (UE) may transmit, in a packet to a base station, information associated with resource configuration/resource requirement corresponding to wireless uplink communications of the wireless communication device. The base station may assign resources to the UE based on the received information. The UE may receive an uplink grant from the base station, with the uplink grant specifying resources for use by the wireless communication device during the uplink communications based on the information previously transmitted to the base station by the wireless communication device. The UE may send the packet at the time a voice call with the UE is initiated, and/or the UE may transmit the information during voice calls in response the UE changing one or more resource configuration parameters during the voice call. The UE may use Robust Header Compression packets of various types to transmit the resource configuration information.

摘要： A method is disclosed for coordinating a user equipment's communication with a network during tune back with C-DRX (connected mode discontinuous receive). When a user equipment tunes back to a network after a tune away or a signal fade, a scheduling request is sent to the network to indicate the tune back as quickly as possible. The user equipment waits for a downlink transmission from the network. When the user equipment does not receive the downlink transmission, the method determines if the connection between the user equipment and the network has been released. The sending of the first scheduling request and any additional scheduling requests is coordinated with the C-DRX configuration so as to maximize the battery savings of C-DRX and minimize the latency of the tune back process in case the user equipment has uplink data to send.
摘要翻译：公开了一种用于在用C-DRX（连接模式不连续接收）回调期间协调用户设备与网络的通信的方法。当用户设备在离开音乐或信号消隐后调谐回网络时，调度请求将被发送到网络，以尽可能快地指示回调。用户设备等待来自网络的下行链路传输。当用户设备没有接收到下行链路传输时，该方法确定用户设备和网络之间的连接是否已被释放。第一调度请求和任何附加调度请求的发送与C-DRX配置协调，以便最大限度地减少C-DRX的电池节省，并且在用户设备具有要发送的上行链路数据的情况下最小化回调过程的等待时间。

摘要： A method for initiating a codec rate change during a VoIP call by a wireless communication device is disclosed. The method can include the wireless communication device establishing a first codec rate for use in the VoIP call during a call establishment phase; using the first codec rate to encode voice data for transmission during a first portion of the VoIP call; determining a channel quality while using the first codec rate; determining that the channel quality satisfies a threshold for requesting a codec rate change; requesting a codec rate change from the first codec rate to a second codec rate in response to the channel quality satisfying the threshold; and using the second codec rate to encode voice data for transmission during a second portion of the VoIP call.
