Method for a User Entity, UE, being adapted to transmit uplink data according to a NR TDD scheme, with a NR bases station, gNB, the UE being further adapted to transmit HARQ-ACK information, being an ACK or a NACK for received data on a downlink channel and a Scheduling Request, SR, may be provided comprising an indication of data or no data to be pending for transmittal on the up-link. The method comprises-establishing if HARQ-ACK info is available in a slot (), —establishing if an SR-PUCCH is present in the slot (), —if no SR-PUCCH present in the slot, generating () a SR, —appending () the SR to the HARQ-ACK, —transmitting () the SR appended to the HARQ-ACK.

Aperiodic scheduling request

Method for a base station communicating with a plurality of User Entities, UE, according to a Time Division Duplex, TDD, access scheme via antennas, the base station being adapted for receiving Scheduling Requests, SRs, from the UEs, a SR indicating a request for scheduling an uplink transmission from a UE. The base station is communicating over a plurality of antennas associated with respective wide beams and narrow beams, a plurality of wide beams covering respective areas, whereby for each wide beam at least one narrow beam form a joint area with a wide beam. The TDD scheme involving at least a Physical Uplink Scheduling Control Channel, PUSCH, and including periodically appearing SR occasions, the base station being adapted for receiving and decoding a transmission from a UE and establishing whether a SR from at least one UE is received in a periodic occasion.

SR handling for analog beamforming

A method performed by a first network node of a wireless communication network for handling uplink signals sent by a UE. The wireless communication network comprises a serving network node responsible for transmitting downlink signals to the UE, and a non-serving network node capable of receiving uplink signals sent by the UE. The non-serving network node is the first network node and the serving network node is a second network node of the communication network, or vice versa. The method comprises receiving an uplink signal from the UE, measuring signal quality on the received uplink signal, and receiving signal quality information from the second network node regarding signal quality measured by the second network node on the uplink signal received by the second network node, to detect imbalances in experienced signal quality between the first network node and the second network node.

Methods and network nodes in a wireless communication network for handling of uplink signals sent by a user equipment

A radio base station (RBS) and a method performed by an RBS for scheduling uplink resources to at least one UE are provided. The RBS comprises at least two receiving antenna branches and the RBS is operable in a radio communication network. The method comprises receiving transmissions from the at least one UE by means of the at least two receiving antenna branches; and determining at least one parameter relating to signal quality of the received transmissions. The method further comprises determining a diversity gain of the at least two receiving antenna branches, wherein the diversity gain is determined based on the determined parameter(s); and scheduling uplink transmissions for the at least one UE based on the determined diversity gain.

Radio base station and a method therein for scheduling uplink resources

A method and apparatus for operating a high speed uplink base station is provided. The base station is adapted to communicate with a first type of user entities and a second type of user entities. The first type of user entities communicate in a first transmission interval and the second type of user entities communicate in a second transmission interval.

TTI channel arrangement and UE to channel assignment

A method for a user entity (UE) transmitting data said data being receivable by at least a serving node (B) and a non serving node (B); the user entity (UE) being adapted for receiving a first signal (ABS GRNT E-AGCH) () from a serving node (B) granting the user entity permission to transmit at a given signalling rate; the user entity (UE) being adapted for receiving a second signal () from a non-serving node (B) instructing the user entity to limit its signalling rate (DOWN E-RGCH). The user entity (UE) is being adapted to transmit data packets and associating a third signal (HAPPY,) and the user entity (UE) is being adapted to transmit data packets and associating a fourth signal (NOT HAPPY,) with the data packet transmission indicating the user entity wishing to being granted permission to use a higher signalling rate than it is currently being permitted to use by the serving node (B). The user entity is being adapted for issuing a signalling rate limitation signal (UE RATE LMT,) to the serving node, indicating the user entity having limited its signalling rate signal below the signalling rate granted to it by the serving node B. There is moreover provided a method for a Node B, which as a non-serving Node B (B) is transmitting on the E-RGCH, a situation signal (E-RGCH CEASE) being indicative of a cease ceased&#x2033; of an interference situation.

Enhanced uplink user entity rate limitation signalling

A telecommunication system comprises a radio network controller (RNC), and a Node-B (NB) for enabling wireless communication with a user terminal (UE). The RNC establishes an enhanced dedicated transport channel (E-DCH) which enables uplink data traffic with a determined maximum data rate from the user terminal (UE) to the NB. The RNC further establishes a high speed DL shared channel (HS-DSCH) which enables downlink data traffic with a determined maximum data rate from the NB to the user terminal. The NB comprises a HSDPA scheduler (HS-S) scheduling the data rate for the DL data traffic via the HS-DSCH and a EUL scheduler (EUL-S) scheduling the maximum data rate for the UL data traffic via the E-DCH. The NB exchanges data rate information between the HS-S and the EUL-S. Furthermore, the NB monitors the quotient (Q) between DL data rate and the UL data rate. When Q fulfils determined traffic conditions the HSDPA scheduler (HS-S) and/or the EUL scheduler (EUL-S) changes the allocation and/or the priority handling of the UL and/or the DL resources.

Allocation and priority handling of uplink and downlink resources

The present invention relates to a method for grant violation detection in an enhanced uplink (UL) telecommunication system. According to the method a radio network controller (RNC) establishes a first enhanced UL transport channel (E-DCH) which enables uplink data traffic with a certain data rate from a user terminal UE at least to a first base station. At least a first downlink transmission is performed to the user terminal UE including a first E-DCH. A Node B NB detects the scheduled data rate on which the user terminal UE transmits and further controls if the scheduled data rate detected is higher than the maximum data rate defined by the first E-DCH channel scheduled grant. If this is the case the Node B NB performs at least a second following downlink transmission including the first E-DCH channel scheduled grant.

Enhanced UL rate violation detection

The invention relates to a wireless telecommunication system for voice and data packet transmission. The system comprises a transmitting unit for transmitting voice and data packets to a receiving unit. The transmitting unit comprises a first discard timer set for a first time period and arranged to start when a first data packet is transmitted from the transmitting unit. The transmitting unit is arranged to suspend the first discard timer when a second power is lower than or equal to a selected second threshold level.
