摘要： A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. The embodiment detects lost synchronization errors for NDI-less retransmission protocols. Protocol synchronization errors are prevented by sending scheduling grants (SCH) on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.

摘要： The present invention relates to method and arrangements for using an identifier of a predefined type, e.g. an RNTI identifying one configuration on an out-band control channel for activating the configuration identifiable by that identifier. The identifier is sent from the network to the UE, when a configuration corresponding to that identifier is to be activated. This implies that both the UE and the radio base station comprise a mapping between each configuration and the corresponding identity of each configuration.

摘要： The invention discloses a method (700) for a cellular system (100), in which traffic can be exchanged between first (110, 120) and second (110, 120) transceivers. The traffic is sent in data units, each of which is given an identifier, and which data units may be divided into segments. A receiving transceiver (110, 120) may send status information in data frames or data units (200, 300) about properly received, partially received, or non-received data units to a sending transceiver, i.e. the transceiver from which the data was sent. In the case (705) of partially or non-received data units, the status information includes (710) information about whether the data unit or units were non-received or partially received, and in the case of one or more partially received data units, which (715) parts of those data units that were not received.

摘要： Methods performed by a wireless device, such as a user equipment, operating in a dormant mode comprise performing a measurement on each of a plurality of resources from a predetermined set of resources or demodulating and decoding information from each of a plurality of resources from a predetermined set of resources, such as a set of beams. The methods further include evaluating the measurement or the demodulated and decoded information for each of the plurality of resources against a predetermined criterion, and then discontinuing the performing and evaluating of measurements, or discontinuing the demodulating and decoding and evaluation of information, in response to determining that the predetermined criterion is met, such that one or more resources in the predetermined set of resources are neither measured nor demodulated and decoded. The methods further comprise deactivating receiver circuitry, further in response to determining that the predetermined criterion is met. The method further comprises receiving, in a first downlink subframe, a first Orthogonal Frequency-Division Multiplexing transmission formatted according to a first numerology and receiving, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology.

摘要： A method and nodes for providing adaptive segmentation in a higher protocol layer interacting with a lower protocol layer. An adaptable segmentation limit
(200,204), defining a threshold of a largest Protocol Data Unit (PDU) that is to be submitted to a lower protocol layer, is deployed at a higher protocol layer interacting with the lower protocol layer. For each Service Data Unit (SDU;201,203) arriving at the higher protocol layer, it is determined if the respective SDU can fit into the segmentation limit or not. Each SDU that do not fit into the segmentation limit is segmented into PDUs (205206) which are smaller than or equal to the segmentation limit, while no segmentation is performed on SDUs that fit into
the segmentation limit.-

摘要： The present invention relates to an procedure for synchronization of re-configuration of RRC procedures between the radio base station and the UE; this is achieved by associating a new configuration to be used by a UE with an additional UE identity. The UE is normally identified by a first UE identity, but is informed in a re-configuration message that the UE also has the additional UE identity. The UE is identified by the additional UE identity when the new configuration is to be activated. Hence, when the radio base station detects that the UE responds to requests, which included the additional UE identity, the radio base station can conclude that the UE has activated the new configuration.

摘要： A fifth-generation wireless communications network includes a server node, radio network equipment and a wireless device. In an example method, a server node receives first user data in response to (i) the wireless device receiving from the radio network equipment information indicating a plurality of uplink access configurations, each uplink access configuration including a random access configuration; (ii) the wireless device receiving an uplink access configuration index; (iii) the wireless device using the uplink access configuration index to identify an uplink access configuration from among the indicated plurality of uplink access configurations, and (iv) the wireless device transmitting the first user data to the wireless communications network according to the identified uplink access configuration. In the example method, further, the server node initiates transmission of second and third user data. This causes the wireless device to (v) receive from the radio network equipment, in a first downlink subframe, a first OFDM transmission formatted according to a first numerology and carrying the second user data, and (vi) receive from the radio network equipment, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology and carrying the third user data, wherein the numerologies have different subcarrier spacings.

摘要： The present invention provides a stall avoidance mechanism that may be used alone or in conjunction with an ambiguity avoidance mechanism in an ARQ protocol. Both mechanisms decrease data delays and increase data throughput rates. Stall avoidance is accomplished by determining whether a stall condition exists with respect to receiving a missing data unit. In one example, only a single timer is needed to avoid stalls. Retransmission ambiguities may be avoided using a retransmission window in the transmitter and/or a receive window in the receiver. Although each mechanism may be used independently of the other, a preferred example embodiment uses a stall avoidance timer, a retransmission window in the transmitter, and a receive window in the receiver.

摘要： A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.
