20220046708 | USER EQUIPMENT FIXED FRAME PERIOD FOR FRAME BASED EQUIPMENT MODE IN UNLICENSED SPECTRUM - Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a fixed frame period (FFP) configured for the UE in a frame based equipment mode. The FFP configured for the UE includes one or more idle periods and a channel occupancy time that is offset from an FFP configured for a base station communicating with the UE over an unlicensed channel. The UE may refrain from transmitting over the unlicensed channel during the one or more idle periods. The one or more idle periods may at least partially overlap with a time period in which the base station refrains from transmitting over the unlicensed channel. Numerous other aspects are provided. | 2022-02-10 |
20220046709 | MANAGEMENT OF SPECTRUM SHARING FOR PRIORITIZED AND NON-PRIORITIZED USERS IN WIRELESS COMMUNICATION SYSTEM - Aspects relate to spectrum sharing for use in a wireless communication network that serves both prioritized and non-prioritized user access terminals. In one example, a user access terminal, e.g., a user equipment (UE), senses an amount of signal energy within a frequency band during one or more sensing intervals in response to a determination that the access terminal is a non-prioritized access terminal. If the amount of signal energy does not exceed a sensed energy threshold, the user access terminal transmits wireless signals following the sensing intervals. On the other hand, if the amount of signal energy exceeds the sensed energy threshold, the user access terminal modifies transmissions while the amount of signal energy sensed during one or more subsequent sensing intervals exceeds the sensed energy threshold. For example, the access terminal may delay or adjust transmissions until the amount of signal energy no longer exceeds the sensed energy threshold. | 2022-02-10 |
20220046710 | SYSTEM AND METHOD FOR MULTIPLE PARALLEL MESSAGING INDICATION - A system and method of terminating any pending listen-before-talk (LBT) attempts after they have been submitted to the physical layer of a system interconnection model if one or more of the LBT attempts succeed. The system and method include receiving a plurality of frequency resources, each of the plurality of frequency resources corresponding to a respective resource occasion. The system and method include performing, for each of the frequency resources, a listen-before-talk procedure in a first layer of an open system interconnection model. The system and method include indicating, to a second layer of the open system interconnection model, a first one of the plurality of frequency resources that succeeded in the respective listen-before-talk procedure. | 2022-02-10 |
20220046711 | ENHANCED TIMING ADVANCED FILTERING - A method implemented in a User Equipment, UE, for a cellular communication system includes transmitting a Random Access (RA) preamble and receiving a Random Access Response (RAR) from a base station (BS) containing a timing advance value, T | 2022-02-10 |
20220046712 | RANDOM ACCESS PROCEDURE - Embodiments of the present disclosure relate to methods, devices and computer readable mediums for random access procedure. The method comprises transmitting, at a terminal device, a random access request in a random access procedure to a network device; in response to receiving, in the random access procedure, from the network device an uplink grant for the terminal device, determining whether a first size of a first data unit indicated by the uplink grant matches a second size of a second data unit stored in a buffer of the terminal device; in response to determining that the first size mismatches the second size, determining a first part of the second data unit for subsequent transmissions. | 2022-02-10 |
20220046713 | METHOD AND APPARATUS FOR RANDOM ACCESS LAYERED PREAMBLES - An operation method of a terminal in a communication system may include: receiving, from a base station, quality of service (QoS) information for preamble groups and information on preambles belonging to each of the preamble groups; selecting one preamble group from among the preamble groups based on the QoS information and a QoS of the terminal; selecting a preamble within the one preamble group based on the information on preambles belonging to each of the preamble groups; transmitting a first message including the selected preamble to the base station; and receiving, from the base station, a second message that is a response to the first message. | 2022-02-10 |
20220046714 | Random Access Response Reception of Random Access Procedure - In some embodiments, a wireless device transmits repetitions of a random access preamble across a plurality of system frames to a base station. The wireless device receives a downlink control information (DCI) including: a system frame number field indicating a system frame number, and a radio resource assignment. The wireless device receives a random access response via the radio resource assignment. In response to the system frame number indicating a system frame of the plurality of system frames, the wireless device determines that the random access response corresponds to the random access preamble. Then, the wireless device transmits one or more transport blocks via an uplink grant indicated by the random access response. | 2022-02-10 |
20220046715 | METHOD AND APPARATUS FOR PROVIDING NON-SCHEDULED NETWORK ACCESS - A terminal device selects are source indicator to be used for non-scheduled access and transmits it to an access device of the network in the non-scheduled access. If it determines based on a response to the non-scheduled access, that it has selected the same resource indicator as another terminal device, it keeps the resource indicator but selects different physical random access channel occasions by setting a time offset for a retransmission with the selected resource indicator. An initial waiting time may be determined by the access device (e.g. based on a traffic amount on the access channel) and transmitted to the terminal device for setting the time offset. Also, a layer (2) error caused by a random access channel resource collision of terminal devices may be determined at the access device and a feedback indicating a non-acknowledgement for layer (2) may be transmitted to colliding terminal devices. | 2022-02-10 |

The user equipment sends, by using at least two beams respectively, SRSs to the access network device on at least two SRS resources associated with the PUSCH resource. The user equipment receives a random access response from the access network device, where the random access response includes beam indication information, and the beam indication information is used to indicate an optimal beam in the at least two beams. | 2022-02-10 |
