EXTENSION OF AN EVALUATION PERIOD OF INTEGRATED ACCESS BACKHAUL MOBILE TERMINATION DUE TO COMMUNICATION OF THE CO-LOCATED INTEGRATED ACCESS BACKHAUL DISTRIBUTED UNIT
The apparatus may be a first device at a first IAB node or the first IAB node itself. The IAB node may be configured to receive a configuration for a first set of reference signals associated with an IAB-MT function of the IAB node, wherein the first set of reference signals overlaps in time with a second set of time periods associated with an IAB-DU function of the IAB node. The IAB node may further be configured to extend an IAB-MT reference-signal measurement period based on the overlap between the first set of reference signals for measurement with the IAB-MT function of the IAB node and the second set of time periods associated with the IAB-DU function of the IAB node.
COVERAGE ENHANCEMENT
The present disclosure proposes various methods for improving coverage. According to an embodiment of the present disclosure, when an unavailable resource exists in a resource set configured for repeated transmission of a physical uplink channel, the UE may determine a resource capable of actually performing repeated transmission of a physical uplink channel within the resource set. According to another embodiment of the present disclosure, when the terminal receives the TPC command within the resource corresponding to the DMRS bundle, the terminal may perform power control based on the TPC command after the resource.
METHOD AND APPARATUS FOR DOWNLINK DATA TRANSMISSIONS
A first resource assignment can be transmitted in a first TTI. First downlink user data corresponding to at least a first transport block in the first TTI in a first set of resources for receiving a first portion of a first downlink user data and second set of resources receiving a second portion of the first downlink user data can be transmitted. The second set of resources can be configured for DCI and can be used instead for downlink user data and the second set of resources may not overlap with the first set of resources. A second resource assignment in a second TTI can be transmitted. Second downlink user data corresponding to at least a second transport block can be transmitted. The second downlink user data can be transmitted in the second TTI in third and fourth sets of resources.
MOBILE TERMINAL AND BASE STATION INVOLVED IN DOWNLINK CHANNEL OPERATIONS INCLUDING RADIO CHANNEL ESTIMATION BASED ON DEMODULATION REFERENCE SIGNAL
The present disclosure relates to a mobile terminal, a base station and respective operation methods. The mobile terminal comprises circuitry, which in operation assumes that a base station is configured to use one of a plurality of transmission beams, receives a downlink control channel candidate and a corresponding demodulation reference signal using one of a plurality of reception beams corresponding to the assumed one of the plurality of transmission beams, performs channel estimation based on the received demodulation reference signal, and, depending on the quality, demodulates the downlink control channel candidate using the channel estimation. The channel estimation is performed using a demodulation reference signal sequence which is generated observing an association which is associating the generated sequence with the assumed one of the plurality of transmission beams such that at least two of the plurality of transmission beams are associated with different demodulation reference signal sequences.
DOWNLINK CONTROL INFORMATION (DCI)-BASED TRIGGERED POSITIONING REFERENCE SIGNALS (PRS)
Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a serving transmission-reception point (TRP), downlink control information (DCI) triggering the UE to measure positioning reference signals (PRS), wherein a code point in the DCI is associated with one or more PRS resources, one or more PRS resource sets, one or more positioning frequency layers, or one or more TRPs, and measures PRS transmitted on the one or more PRS resources, the one or more PRS resource sets, the one or more positioning frequency layers, or the one or more TRPs.
METHOD FOR TRANSMITTING SYNCHRONIZATION/PHYSICAL BROADCAST CHANNEL BLOCK AND APPARATUS
This application provides a method for transmitting an SS/PBCH block and an apparatus. The method includes: A terminal device receives one SS/PBCH block in an SS/PBCH block burst set, and then obtains indication information based on the one SS/PBCH block. The indication information may be used to indicate candidate indexes of at least one SS/PBCH block in the SS/PBCH block burst set, and a quantity of the candidate indexes is greater than 64. For example, the quantity of candidate indexes may be 128, 160, 180, 196, 240, or the like. A network device may not be limited to 64 candidate indexes. In other words, a quantity of candidate positions used to send the SS/PBCH block is not limited to 64. Therefore, the network device may send a larger quantity of SS/PBCH blocks to the terminal device.
METHOD FOR TRANSMITTING AND RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS FOR SUPPORTING SAME
The present disclosure relates to a wireless communication system. Specifically, provided is a method and an apparatus for supporting same, the method comprising the steps of obtaining random access procedure-related message A, message A including a physical random access channel (PRACH) preamble and a physical uplink shared channel (PUSCH); transmitting message A; and receiving random access procedure-related message B as a response to message A, wherein the PUSCH comprises a demodulation reference signal (DM-RS), and PRACH preamble is mapped to (i) one or more DM-RS ports and (ii) one or more DM-RS sequences on the basis of indices of respective (i) one or more DM-RS ports and indices of respective (ii) one or more DM-RS sequences.
CSI-RS TO ENHANCE PDCCH TRANSMISSION OR RECEPTION
Aspects are provided which enhance receiver performance of PDCCH by allowing a base station to associate a configured PDSCH CSI-RS with a PDCCH for channel estimation and reception by a UE. A UE receives a reference signal associated with a physical downlink shared channel (PDSCH) from a base station, and uses the reference signal to receive a physical downlink control channel (PDCCH) and/or measure the PDCCH and feedback a corresponding channel measurement for the PDCCH. A base station configures a reference signal associated with a PDSCH for transmission of a PDCCH and/or reception of a corresponding channel measurement for the PDCCH as feedback from the UE, and transmits the reference signal to the UE.
METHOD AND DEVICE IN NODES USED FOR WIRELESS COMMUNICATION
The present disclosure provides a method and a device in a node for wireless communications. A first node determines a first resource set and a first resource set group from M resource sets; and monitors a first-type channel in the first resource set group in a first time window. Any two of the M resource sets are overlapping in time domain, and the first resource set group comprises the first resource set; any of the M resource sets is linked to one or two spatial states; a second resource set is any of the M resource sets different from the first resource set; whether a first condition is fulfilled is used to determine whether the second resource set belongs to the first resource set group. The above method avoids performance loss resulting from the UE's unnecessary abandonment of monitoring over some PDCCH candidates.
TRANSMISSION OF REFERENCE SIGNAL RESOURCES AND CONFIGURATION THEREOF
There is provided mechanisms for transmission of reference signal resources from a terminal device. A method is performed by the terminal device. The terminal device comprises at least two antenna panels and a baseband chain operable to be switched between the at least two antenna panels. The baseband chain is thereby connected to each of the antenna panels one at a time. The method comprises distributing a fixed set of reference signal resources among the at least two antenna panels by selecting which beams are to be used for transmission of the reference signal resources. The reference signal resources are distributed among the at least two antenna panels according to antenna panel selection information. The method comprises transmitting each of the reference signal resources in a respective one of the beams as the baseband chain is connected to each antenna panel used for generating the beams.
