摘要:
Wireless communications systems as described herein may be configured to provide user equipment (UE) assisted information for caching data at a network node external to a core network (CN). In some cases, the UE may provide an acceleration indicator (AI) that a base station may receive and identify as caching information. The base station, upon identifying that the AI is present in an uplink packet, may transmit the packet to a gateway having a local cache. If the uplink packet does not have an AI, the base station may route the uplink packet according to an address (e.g., a uniform resource locator (URL)) contained in the packet.

Techniques are described that provide network assisted multi-subscription physical layer sharing at a user equipment (UE) by transmitting a multi-subscription coordination capability to a network, establishing a link for a first subscription with the network based on the multi-subscription coordination capability, and establishing a second subscription with the network using the link based on the multi-subscription coordination capability, the first subscription is associated with the second subscription.
摘要:
A wireless device may receive a radio link control (RLC) protocol data unit (PDU) from a lower layer (e.g., from a media access control (MAC) layer) when processing communications (e.g., packets) received from another wireless device. The receiving wireless device may identify that the PDU is an RLC service data unit (SDU) segment based at least in part on an indication corresponding to a sequence number associated with the RLC SDU segment. The receiving wireless device may then determine that the RLC SDU segment is received out of order based on previously received PDUs or previously received RLC SDU segments, and initiate a reassembly timer based on the out of order determination for the RLC SDUs. If the remaining RLC SDU segments (e.g., that complete the RLC SDU) are received before reassembly timer expires, the wireless device may reassemble the RLC SDU to be passed to a higher layer.
摘要:
Increased symbol length of uplink pilot time slots (UpPTS) in special subframes is disclosed in which a configuration of a first special subframe may be independent from configuration of a second special subframe in the same frame, such that the first UpPTS of the first special subframe is longer than the second UpPTS of the second special subframe. The second UpPTS of the second special subframe may also be longer than legacy UpPTS length in select configurations. A serving base station may select the special subframe configurations in order to balance sounding reference signal (SRS) capacity for compatible user equipments (UEs) and downlink throughput for legacy UEs. The selected special subframe configurations may be transmitted by the serving base stations. In additional aspects, compatible UEs may be configured with at least two separate SRS power control parameters for use in the additional and legacy UpPTS symbols.
摘要:
Enhancement of long term evolution (LTE) time division duplex (TDD) carrier aggregation for half duplex user equipments (UEs) is discussed. In one aspect of enhanced TDD carrier aggregation, the UE monitoring for a control signal indicating subframe configuration for each TDD cell of an aggregated set of TDD cells in the same band. The UE may determine the downlink subframes and receive downlink transmissions on such subframes based on the control signal. In another aspect, the UE compares the number of scheduled uplink and downlink subframes between the TDD cells in the same band to determine the downlink error-control messaging timing for each cell.

摘要:
A method and apparatus for reducing data congestion in Clos networks is disclosed. A congestion detector is provided at an output port of a first layer of the Clos network. A pause timer is provided at an input port of a second layer of the Clos network. The congestion detector generates a feedback message indicating a data congestion level of the output port, and the pause timer determines a pause duration based on the feedback message. For example, the pause duration may be proportional to the congestion level of the output port of the first layer. A pause signal generator may also be provided at the input port to generate a first pause signal based on the pause duration. The pause signal generator may further output the pause signal to a transmitting device to suspend a transmission of data for the pause duration.
