摘要： A method in a sending node of a communications network includes: encoding a transport block, TB, including data of at least one protocol data unit, PDU, to generate a code block group, CBG, comprising one or more code blocks; defining a CBG header indicative of a starting location of a first PDU within the CBG; and transmitting the CBG including the CBG header. A method in a receiving node includes: receiving one or more code block groups, CBGs, each CBG comprising a CBG header indicative of a start location of a first protocol data unit, PDU, within the CBG; attempting to decode each received CBG; responsive to failing to decode a first CBG, attempting to decode a second CBG, and responsive to successfully decoding the second CBG: identifying the start location of the first PDU in the second CBG; buffering data of the second CBG prior to the identified start location; and forwarding data of PDUs following the identified start location.

The method comprises the steps of : - starting a first timer when the mobile station enters a dormant state - while the first timer is counting and prior to its reaching a prefined value T1, sending a layer 2 location update message whenever the MS performs an idle handoff, or sending an MS page to the sector indicated by the most recent layer 2 location update message received from the MS, - starting a second timer when the first timer reaches T1 - while the second timer is running and prior to its reaching a predefined value T2, sending a layer 2 location update message whenever a further criterion is met, or sending an MS page to the sectors surroiunding the sector indicated in the most recently received layer 2 location update message consistent with the further criterion used, and - after the second timer has reached T2, sending no further layer 2 location update messages, or sending an MS page message to all network sectors. In a second embodiment, a sinle timer, which is reset after reaching T1, is employed in a similar location update-method.

摘要： The present invention provides a method and apparatus for improving wireless communication network performance and efficiency, based on detecting the occurrence of grant loss in relation to the transmission of scheduling grants to mobile terminals over a downlink control channel. Grant loss detection is based on detecting erasure events corresponding to the transmitted scheduling grants, and the incidence of grant loss with respect to a given mobile terminal can be tracked and used to compensate the control value(s) used for link adaptation of the downlink control channel, with respect to that terminal. Additionally, or alternatively, when a given grant is determined to be lost, a new grant is sent and the HARQ redundancy version is reset for the newly scheduled transmission.

摘要： A radio user equipment (UE) mobility status is determined in a communications node. UE mobility status measurements associated with the UE communicating over a radio channel are performed. The UE mobility status corresponds to a degree of variation of the radio channel over time. Channel characteristics of the radio channel at a first time and at a second later time are determined. Based on the determined channel characteristics, a channel characteristic error metric is determined and compared to a predetermined threshold. The UE mobility status is determined based on one or more iterations of the threshold comparison.

摘要： A method and apparatus is provided for assigning resources for an acknowledgement channel, such as the PHICH in LTE systems. A list of acknowledgement channels for a group of scheduled mobile terminals is generated. The list is sorted in descended order of the required transmit energies for the corresponding mobile terminals. The acknowledgement channels are then assigned to channel groups one at a time in sorted order to an available channel group with the lowest cumulative transmit energy. By sorting the channel list before assigning resources, the variance in the transmit energies for different channel groups is reduced. Given enough number of acknowledgement channel groups, the small variance in the transmit energies for different channel groups implies improved error rate performance.
摘要翻译：提供了一种用于为LTE系统中的诸如PHICH之类的确认信道分配资源的方法和装置。生成一组调度的移动终端的确认信道的列表。列表按照相应移动终端的所需发射能量的降序排列。然后将确认信道按照排序顺序一次一个地分配给具有最低累积发送能量的可用信道组的信道组。通过在分配资源之前对信道列表进行排序，减少了不同信道组的发射能量差异。给定足够数量的确认信道组，不同信道组的发射能量的小变化意味着提高的误码率性能。
