Abstract: Systems, devices and methods are provided for incorporating a quality of experience (QoE) assessment into requests or negotiations for a particular quality of service (QoS) for an application in a communications network. A network may provide service in accordance with a particular set of QoS parameters in order to meet a user's requested QoE. A user may select a particular QoE for an application depending on costs associated with the corresponding sets of QoS parameters available from the network. Functionality to determine the correlation between a user's QoE and sets of QoS parameters may be implemented primarily in a user's electronic communications device, primarily in a network device, or in both of these devices. A separate device may be used for determining the QoE and corresponding sets of QoS parameters for various services or applications.

Abstract: A wireless communications system including a base station, a relay device, and a terminal device. The terminal device can transmit one or more first type access request messages to request uplink resources from the base station, and if no response to the first type access request messages is received from the base station, transmit a second type access request message. The base station is responsive to a first type access request message received from the terminal device to transmit an allocation of uplink resources to the terminal device. The relay device is responsive to a second type access request message received from the terminal device to transmit a relayed access request message to request the base station to allocate uplink resources to the terminal device. The base station is responsive to the relayed access request message to transmit an allocation of uplink resources to the terminal device.

Abstract: Forward Error Correction (FEC) is an essential component of most digital communication systems. The decoders for the FEC perform better when working in soft-decision mode using the Log Likelihood Ratios (LLRs) as the input. Spatial Multiplexing (SM) with Multiple Input Multiple Output (MIMO) is used in many systems for providing high data rate. When SM-MIMO is used in conjunction with FEC, it is important for SM-MIMO decoders to provide soft channel bits to the FEC decoder. The complexity of the SM-MIMO decoders is generally very high, especially when LLRs need to be generated for each bit of the decoded symbol. Conventional methods for LLR generation in SM-MIMO decoders require the storage and sorting of partial and cumulative distance. A method and apparatus are disclosed that compute the LLRs on the fly without requiring extensive storage or sorting of partial and cumulative distance metrics.

Abstract: Systems and techniques for managing helper cells in coordinated multipoint processing. Bandwidth assistance is requested from one or more cells operating in a network. In response to demand price and headroom information provided by a plurality of cells receiving the request, a set of potential helper cells is rank ordered and identified one or more helpers is identified from the ordered set and a candidate helper set is assembled based on bandwidth performance assistance criteria. A new request for bandwidth assistance is made. In response to new demand price and headroom information obtained from the candidate helper set, a determination is made whether sufficient iterations have been performed. If sufficient iterations have not been performed, the process is repeated, and if sufficient iterations have been performed, a requesting cell proceeds to operate while receiving bandwidth assistance from the assembled set.

The method is characterized in that the terminal receives, from the network, an identifier that can understand whether there are any changes in the BBU, the RRU, and the cell, and through the received identifier understands whether there are one or more changes among the BBU, the RRU, and the cell, and selectively receives, from the network, the only system information required for any one among the BBU change, the RRU change, and the cell change.

Abstract: A base station will determine both that a served device's power headroom is threshold low and that the device's downlink receive signal strength is threshold low. In response to at least determining both that the device's power headroom is threshold low and that the device's downlink receive signal strength is threshold low, the base station will then begin applying an uplink coverage boosting process for the device, including limiting or reducing the number of frequency blocks that the base station allocates to the device for uplink transmission per transmission time interval, to help increase the device's per-frequency-block transmission power and thus the device's uplink communication quality. This could be usefully carried out with respect to voice over Long Term Evolution (VoLTE) uplink coverage boosting (VUCB) for instance, to help improve voice communication quality.
