  • Publication number: 20160165636
    Abstract: The present invention relates to methods and arrangements for facilitating an efficient connection setup. The present invention specifies rules for defining the signaling of connection setup messages from user equipments such as to apply one single transmission if an assigned uplink transmission grant for transmitting the connection setup messages is sufficiently large while applying separate transmissions if the size indicated in said uplink transmission grant is not sufficient. Thus, a sufficiently large grant allows a parallel execution of the connection setup messages.

  • Patent number: 9137765
    Abstract: Methods and arrangements for adjusting timing of transmissions in a radio communication system in which aggregation of component carriers is employed are disclosed. A base station sends a first TA command applicable to a first component carrier to a user equipment. A need to maintain different uplink transmission timing for the first user equipment component carrier and second uplink component carrier is detected by the base station. The base station then sends a second TA command based on the detected need to maintain different uplink transmission timing. The second TA command is applicable to uplink transmissions on the first component carrier and/or the second component carrier. The user equipment adjusts uplink transmissions on the first component carrier and/or the second uplink component carrier based on the second timing advance command.

  • Publication number: 20150124757
    Abstract: A radio access network comprises a donor base station node (29) and a relay base station node (20). The relay base station node (29) participates in communications across a first radio interface with a wireless terminal (30) and also participates in communications over a backhaul link across a second radio interface, the second radio interface reusing at least some functionality of the first interface. The donor base station node (28) configures a subframe configuration pattern. The subframe configuration pattern is arranged to specify which subframe(s) of a frame structure may be utilized for the backhaul link. As a result of subframe configuration, a HARQ process state in a HARQ process at one of the base station nodes is known by the other base station node by any of several operational modes.

  • Publication number: 20150043547
    Abstract: A method and mobile terminal for providing uplink scheduling information to a scheduler in a wireless telecommunication system. When a logical channel having data available to transmit triggers a buffer status report, the mobile terminal determines whether a priority level associated with the logical channel exceeds a predefined threshold. If so, the mobile terminal performs a scheduling request procedure with the scheduler. If not, the mobile terminal delays the scheduling request procedure until a predefined timing event has occurred. The predefined timing event may be at least one of expiration of a timer, a radio bearer associated with the logical channel becoming active, and if the scheduling request procedure is being performed using a contention-based random access, contention resolution succeeding for the mobile terminal.

  • Patent number: 8913565
    Abstract: A method in a user equipment for requesting that a base station schedule the user equipment for an uplink data transmission to the base station is provided. The user equipment comprises a buffer. Directly or indirectly responsive to receiving data into the buffer to be transmitted to the base station, the user equipment generates a scheduling request trigger. The scheduling request trigger is configured to trigger the sending of a scheduling request to the base station if the trigger is pending at the next scheduling request opportunity, and to remain pending until it is cancelled. The user equipment cancels the pending scheduling request trigger when the data is accounted for in a buffer status report, which reports the size of the buffer to the base station, or when the data is included directly in a scheduled uplink data transmission whichever occurs first.

  • Patent number: 8861474
    Abstract: Uplink transmission scheduling requests (SRs) may be prohibited for a lower priority data flow, logical channel group (e.g., VoIP configured with semi-persistent resource allocation), or other grouping but may still be triggered for higher priority traffic (e.g., data connected to a signaling radio bearer (SRB)). More efficient scheduling is also achieved by allowing an uplink transmission scheduler to distinguish between different priority flows or groups (e.g., LCGs) without a buffer status report (BSR), As a result, when a semi-persistent resource is scheled for the lower priority data, there is less delay for high priority data while eliminating uplink and downlink control signaling, i.e., fewer scheduling requests (SRs) and uplink grants, for the lower priority data.

  • Patent number: 8824347
    Abstract: Methods and apparatus for controlling discontinuous receiver operation in a wireless communication device are disclosed. In an exemplary embodiment, a wireless communication device (150) configured to monitor a downlink signal during a series of regularly scheduled awake intervals and monitor the downlink signal for retransmissions during retransmission-monitoring intervals scheduled at a first predetermined delay from each detected data transmission to the receiver includes a control circuit (175) configured to detect that a first retransmission-monitoring interval overlaps a previously scheduled radio activity during which the receiver is unavailable to monitor the first downlink signal, such as a measurement gap, and to adjust the first retransmission-monitoring interval, add an additional retransmission-monitoring interval, or both, responsive to said detecting.

  • Patent number: 8767644
    Abstract: In one aspect of the disclosed teachings, associating a plurality of contention-based uplink grants with a range of uplink resource blocks allows one contention-based uplink grant message to signal the entire plurality of grants. As an example in the LTE context, the signaling load on the PDCCH is reduced by using a single contention-based uplink grant message to signal a plurality of contention-based uplink grants. The message indicates an allocated set of uplink resource blocks and the number of separate uplink resource grants represented by the set is known or signaled, such that user terminals recognize that separate subsets of uplink resource blocks within the set each correspond to a separate contention-based uplink grant. Information included in the contention-based uplink grant message, or otherwise signaled can be used to control the probability at which the user terminals attempt contention-based uplink transmissions and/or to control the MCS used for such transmissions.

  • Patent number: 8750333
    Abstract: Fields such as sequence numbers and length indicators of protocol layers are extended in extended headers so as to be backwards compatible with corresponding legacy headers. The existing fields of the legacy headers are not directly extended. Instead, existing fields are logically concatenated with other fields of the extended header. Whether the extended fields or legacy fields will be used can be determined dynamically based on current transport block size or semi-statically by higher layers.

  • Patent number: 8699997
    Abstract: The present invention relates to methods and arrangements for handling UE capability information a mobile telecommunications network wherein an eNodeB (100) receives (60) information regarding the UE capability information from the UE (120) and stores (70) the information. The eNodeB (100) sends (80) the UE capability information to the EPC, i.e. the MME (130). The MME (130) receives and stores (90) the UE capability information. When the UE (120) transits from idle to active state, does an initial attach or when a part of the UE capabilities have changed, it sends (10) a message Ma to the eNodeB (100) regarding the update. The eNodeB (100) receives the message and sends (20) it to the MME (130). The MME (130) sends (30) a response associated with the previously stored UE capability information to the eNodeB (100). The eNodeB (100) decides (40) if the UE capabilities stored in the MME (130) is up-to-date based on the message sent from the UE (120) and the received response from the MME (130).
