  • Publication number: 20210367744
    Abstract: Example embodiments of the present disclosure relate to channel information transmitting for dormant bandwidth part. According to embodiments, a solution for channel information transmitting for dormant bandwidth part has been proposed. A terminal device is configured a periodicity when an active downlink (DL) bandwidth part (BWP) is a dormant BWP. The periodicity is different from a further periodicity which is configured and used when the active DL BWP is a non-dormant BWP. The terminal device uses resourced configured for the active uplink (UL) BWP but with the different periodicity. In this way, it allows sounding reference signal (SRS)/channel state information (CSI) reporting without duplicating configurations of BWPs. It can configure a required longer periodicity but reduce the SRS configuration for each UL BWP.

  • Publication number: 20210314052
    Abstract: Example embodiments of the present disclosure relate to reporting beam failure. A terminal device performs beam failure detection on a first number of serving cells configured for the terminal device. The terminal device determines information to at least indicate respective results of the beam failure detection on a second number of serving cells among the first number of serving cells, where the second number is smaller than the first number. The determined information is transmitted by the terminal device to a network device serving the terminal device using a resource allocated for the terminal device. Based on the information, the network device determines an overall result of the beam failure detection performed on the first number of serving cells.

  • Publication number: 20210281296
    Abstract: Method, apparatus, and computer program product for a user equipment to receive a downlink control information message from an access point in a wireless communications network and to echo a new beam index in the PUCCH feedback resource in response to the message indicating a PUCCH feedback resource and containing a beam change indication or in response to the message indicating a downlink grant containing a beam change indication MAC control element but no CSI-feedback is scheduled for the PUCCH feedback resource. If a scheduling request resource is indicated by the message or the MAC control element, the user equipment is triggered to transmit a scheduling request on that indicated scheduling request resource. If a scheduling request resource is not indicated by the message or the MAC control element, the user equipment is triggered to perform a scheduling request procedure on a periodic scheduling request resource.

  • Publication number: 20210274530
    Abstract: Embodiments of the present disclosure relate to a method, device and computer readable storage media for optimizing buffer state report (BSR) for limited traffic mix. In example embodiments, whether a short or long B SR being reported is up to the configuration of LCG or the configuration of LCH within the LCG. In this way, minimum overhead for low bit rate services can be kept and thus a good coverage can be achieved, while the reporting information can be increased for other traffic.

  • Publication number: 20210266971
    Abstract: Example embodiments of the present disclosure relate to a solution for determining a contention resolution timer. In an aspect, a first device receives, from a second device, an indication to perform Msg3 transmission. The first device transmits, to the second device, information of the first device for contention resolution. In case a configuration of a 4-step random access channel is unavailable in an active bandwidth part for the first device, the first device determines a duration for monitoring a contention resolution message based on one of: a first configuration of a 2-step random access channel in the active bandwidth part, or a second configuration of a 4-step random access channel in a bandwidth part different from the active bandwidth part. Example embodiments of the present disclosure can improve the performance of a random access procedure.

  • Publication number: 20210243810
    Abstract: In example an embodiment, according to the method, a timer is started to monitor selection of a RA resource in response to a RA procedure for accessing a network device being initiated. The timer is configured with expiration time. The timer is stopped in response to a RA resource being selected for transmitting a RA preamble to the network device. A preamble transmission counter is incremented in response to the timer expiring. The preamble transmission counter records the number of transmitted RA preambles. A failure of the RA procedure is indicated in response to the incremented preamble transmission counter exceeding a threshold. The embodiment enables completion of the RA procedure regardless of an out of coverage situation where no beam is available to be selected for transmitting a RA preamble.

  • Publication number: 20210195657
    Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable storage media for determining a transport block size (TBS) for Contention Free Random (CFRA) in a random access procedure. In example embodiments, a CFRA request is transmitted by a terminal device to a network device during a random access procedure. The terminal device receives a random access to the CFRA request from the network device. The random access response indicates a TBS granted by the network device for use in transmission. Based on the granted TBS, the terminal device transmits, to the network device, a first data block with the granted TBS or a second data block to be transmitted and stored in a buffer. In the way, the data may be avoided, and the data transmission efficiency may be improved.

  • Publication number: 20210185642
    Abstract: Embodiments of the present disclosure relate to methods and devices for transmission by selecting between uplink resources. According to a method implemented by a terminal device in a communication system, a configuration of a first resource is received from a network device, the first resource being a grant-free resource. An uplink grant is received from the network device, indicating a second resource for use in a transmission time interval. The terminal device determines, based on the configuration of the first resource, whether the first resource is available in the transmission time interval. In response to determining that the first resource is available and possibly in response to a predefined condition associated with a logical channel for the terminal device is met, the terminal device transmits uplink data to the network device using the first resource.
