  • Patent number: 11825508
    Abstract: The invention relates to methods for improving a scheduling request transmission between a UE and a base station. The transmission of the scheduling request is postponed, by implementing a threshold that the data in the transmission buffer has to reach, before a transmission of the scheduling request is triggered. In one variant, the data in the transmission buffer needs to reach a specific amount, to trigger a scheduling request. The invention refers to further improvements: the PDDCH monitoring time window is delayed after sending a scheduling request; the dedicated scheduling request resources of the PUCCH are prioritized differently such that low-priority scheduling requests are transmitted less often.

  • Patent number: 11825347
    Abstract: For switching between packet duplication operating modes, methods, apparatus, and systems are disclosed. One apparatus includes a processor and a transceiver that communicates with a mobile communication network via a radio bearer. The processor determines whether PDCP packet duplication associated with the PDCP protocol entity is to be activated and, if so, communicates with a mobile communication network according to a packet duplication mode of operation. Otherwise, the processor determines whether a split threshold value of the PDCP protocol entity is set to a predefined value, communicates with the mobile communication network according to a first split bearer mode of operation in response to determining that the split threshold value is set to the predefined value, and communicates with the mobile communication network according to a second split bearer mode of operation in response to determining that the split threshold value is not set to the predefined value.

  • Publication number: 20230361974
    Abstract: The invention relates to a method for transmitting a periodic channel quality report (CSI) and/or a sounding reference symbol (SRS) from a UE to an eNodeB. To avoid double decoding at the eNodeB in transient phases, a deterministic behavior of the UE is defined by the invention, according to which the eNodeB can unambiguously determine whether the UE will transmit the CSI/SRS or not. According to one embodiment, the UL grants and/or DL assignments received until and including subframe N-4 only are considered; UL grants and/or DL assignments received by the UE after subframe N-4 are discarded for the determination. Additionally, DRX-related timers at subframe N-4 are considered for the determination. In a second embodiment, DRX MAC control elements from the eNodeB, instructing the UE to enter DRX, i.e., become Non-Active, are only considered for the determination if they are received before subframe N-4, i.e., until and including subframe N-(4+k).

  • Publication number: 20230354407
    Abstract: Apparatuses, methods, and systems are disclosed for determining which transmission to prioritize between overlapping SL and UL transmissions. One apparatus includes a processor and a transceiver operable on an uplink channel and on a sidelink channel. The processor identifies a sidelink transmission and an uplink transmission planned for an overlapping time and determines a transmission type of the sidelink transmission and of the overlapping uplink transmission. The processor prioritizes the uplink transmission over the sidelink transmission in response to the transmission type of the uplink transmission being a random-access procedure message for a primary cell. The processor prioritizes the sidelink transmission over the uplink transmission in response to the transmission type of the uplink transmission being a reference signal transmission.

  • Patent number: 11805530
    Abstract: The invention relates to a method for dynamically indicating a TDD reconfiguration to the mobile station by encoding the dynamic TDD re-configuration indication into the DCI or CRC calculated for the DCI. In one embodiment, the TDD configuration indication is implicitly encoded as an RNTI into the CRC, when scrambling the CRC for the DCI with a TDD-RNTI. In another embodiment, the TDD configuration indication is part of the DCI payload, while the CRC for the DCI is scrambled with a cell identifier, identifying the target cell for which the dynamic TDD re-configuration is to be applied. In still another embodiment, the TDD configuration indication is part of the DCI payload, where the DCI payload further includes an invalid parameter indicating to the mobile station that the DCI carries the TDD configuration indication.

  • Publication number: 20230336313
    Abstract: Apparatuses, methods, and systems are disclosed for handling autonomous retransmission. One apparatus includes a transceiver that operates on a first BWP. The apparatus includes a processor that generates a first MAC PDU for transmission on a first CG associated with a first HARQ process. The processor deprioritizes the first CG in response to detecting a higher priority UL transmission overlapping with the first CG. The processor switches an active BWP from the first BWP to a second BWP after deprioritizing the first CG. The processor prevents the first HARQ process from triggering a transmission of the first MAC PDU on a second CG associated with the first HARQ process on the second BWP.

  • Patent number: 11792800
    Abstract: The invention relates to the allocation of radio resources by a transmitting user equipment to perform a plurality of direct SL transmissions to one or more receiving user equipments. The allocation of radio resources within a SC period is restricted, for the SC period, by a maximum number of SL processes with which a transmitting user equipment is configured. A plurality of SL grants is acquired. Among the acquired SL grants a number of those SL grants is selected that have most recently been acquired before the start of the subsequent SC period. A plurality of SL processes is associated such that each of the plurality of SL process is associated with a different one of the selected number of SL grants. For each of the plurality of the SL processes, the radio resources are allocated. Each of the plurality of SL transmissions comprises at least one SCI transmission and at least one data transmission over the SL interface.

  • Publication number: 20230328575
    Abstract: In order that devices with reduced capabilities be explicitly identifiable by networks, to flexibly allow and/or restrict their access to the networks, a user equipment (UE) first determines (1102) at least one set of user equipment capabilities. The UE may determine whether an access attempt is authorized based on barring information broadcast by the network to be accessed (specifying e.g. whether a reduced capability UE is allowed to access a cell). The UE then transmits (1104) an access request message to a network device. The access request message includes information corresponding to the at least one set of user equipment capabilities.

  • Publication number: 20230328740
    Abstract: The present invention relates to a D2D capable a communication method and to a transmitting user equipment, which transmits data to a receiving user equipment over a direct link data channel, uses the services of the eNodeB in order to have resources allocated for transmitting said data. To this end the UE sends to the eNB scheduling information using resources of a subframe dedicated for standard uplink communication through the eNodeB, rather than using resources on the subframe dedicated to D2D data transmission. In order to allow the eNB to distinguish whether the received scheduling request is for allocating resources for transmitting data over the direct link channel or over the eNB, UE may send along with the scheduling information also identification information associated to the scheduling information.

  • Patent number: 11785500
    Abstract: An invention relates to methods for transmitting a buffer status report (BSR) in a mobile communication system, more particularly to the definition of rules for triggering, generating and transmitting BSRs. The invention also relates to a data transmission method utilizing new rules to decide data of which radio bearers is transmitted within a given transmission time interval. Moreover, the invention relates to scheduling method for radio resources that is taking into account additional scheduling-relevant information from the buffer status reporting and/or data transmission method. To avoid unnecessary grants from the network and to suggest an advanced handling of data transmissions the invention suggests a buffer status reporting and data transmission schemes that take into account the scheduling mode of data of radio bearers pending for transmission to decide whether to report on it in a buffer status report, respectively, whether to multiplex the data to a transport block for transmission.
