For example, a device may include a wireless communication unit to communicate an aggregate data unit including a plurality of data units in an increasing order of sequence numbers assigned to the data units, such that a first data unit having a first sequence number always precedes a second data unit having a second sequence number, greater than the first sequence number. | 2015-04-16 |
20150103792 | HETEROGENEOUS NETWORK PARTITION IN TDD BEYOND RADIO FRAME - Maintaining uplink hybrid automatic repeat request (HARQ) compatibility with extended radio frames includes partitioning subframe groups over an extended radio frame having a length of time greater than a time defined for a single radio frame. User equipment (UE) suspends PUSCH (physical uplink shared channel) retransmission in the extended radio frame, in accordance with hybrid automatic repeat request (HARQ) timing of a subframe group assigned to the UE. | 2015-04-16 |
20150103793 | COMMUNICATIONS SYSTEM, BASE STATION, USER EQUIPMENT, AND SIGNALING TRANSMISSION METHOD - The present invention provides a communications system, a base station, a user equipment, and a signaling transmission method. The system includes: a first base station and a second base station. User data transmission exists between the first base station and a UE; the first base station performs control signaling interaction with the UE by using a first signaling radio bearer; and the second base station performs control signaling interaction with the UE by using an SRB0, an SRB1, or an SRB2, where the first signaling radio bearer is different from the SRB0, the SRB1, and the SRB2. The technical solutions of the present invention can solve a problem of configuring a radio resource of an air interface connection between an enhancement-layer base station and a UE. | 2015-04-16 |
20150103794 | WIRELESS COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION METHOD - To suppress concentration of channel quality information requests and reports in a case of discontinuously transmitting reference signals at specific resources in a time domain, and thereby preventing degradation in throughput. A transmission apparatus transmits an instruction of CSI request distributed for each reception apparatus in a subframe concurrently with or earlier than a reference signal CSI-RS to each of reception apparatuses. Each of the reception apparatuses detects the CSI request from the transmission apparatus and calculates CSI from a channel estimation value of CSI-RS received thereafter. Then, the reception apparatus identifies CSI report subframe of the own apparatus from CSI report interval information of a given time interval notified in advance, the subframe in which the CSI request is detected and transmission timing of CSI-RS, and transmits a feedback signal including CSI report value by using PUSCH at the timing of the CSI report subframe. | 2015-04-16 |
