摘要： In order to minimize the control signaling overhead associated with transmitting CQI data from mobile stations to base stations in wireless communication networks supporting MU-MIMO, the CQI during MU-MIMO operation is estimated based on SU-MIMO CQI data, mobile station geometry data, and mobile station PMI (Precoding Matrix Index) data. More particularly, the base station maintains and updates a knowledge pool that correlates geometry data and learned impact of interfering precoder data to degradation of CQI values responsive to switching from SU-MIMO operation to MU-MIMO operations. Then, when the base station switches from SU-MIMO operation to MU-MIMO operation, it consults the knowledge pool to predict the degradation in CQI and subtracts them from the known, pre-switching SU-MIMO CQI feedback data for each relevant mobile station to predict the post-switching MU-MIMO CQIs for that mobile station.

摘要： A first user equipment (UE) is configured to receive from a base station a signaling comprising indication of one or more time-frequency resources and an indicator indicating a time gap, and transmit a transport block (TB) to a second UE using the one or more time-frequency resources. For each of the time-frequency resources, the first UE monitors a hybrid automatic repeat request (HARQ) feedback from the second UE, using a physical sidelink feedback channel (PSFCH) resource; and transmits to the base station a HARQ feedback report signal based on the HARQ feedback or absence thereof, in a physical uplink control channel (PUCCH), using a single PUCCH resource determined based on the time gap from a last one of the PSFCH resources.

摘要： Some embodiments of the present disclosure provide for use of a linear chirp signal as a basis for a sensing signal. Modification of the linear chirp signal by a signature function can allow a receiver of the sensing signal to determine an identity for a source of the sensing signal. Accordingly, upon processing the received sensing signal to obtain path parameter estimates, the receiver can direct a transmission of an indication of the path parameter estimates to the source of the sensing signal. Aspects of the present application relate to performing multi-node, multi-path channel estimation on the basis of processing the received sensing signal. Conveniently, the processing is performed with low complexity.

摘要： The present disclosure relates, in part, to non-terrestrial communication systems, and in some embodiments to the integration of terrestrial and non-terrestrial communication systems. Non-terrestrial communication systems can provide a more flexible communication system with extended wireless coverage range and enhanced service quality compared to conventional communication systems. A method representative of aspects of the present application includes receiving, by an apparatus connected in a first sub-system, from a radio access network, configuration information for performing a channel condition measurement on a second sub-system, reporting, by the apparatus to the radio access network, channel condition measurement of a downlink reference signal received from the second sub-system, transmitting, by the apparatus, a wireless transmission to the second sub-system responsive to the channel condition measurement meeting a predefined condition.

摘要： Systems and methods are disclosed for providing H-ARQ transmissions in respect of a set of horizontal code blocks are combined in a code. Retransmissions contain vertical parity check blocks which are determined from verticals from the set of horizontal code blocks. Once all the vertical parity check blocks have been transmitted, a new set may be determined after performing interleaving upon either the content of the horizontal code blocks, in the case of non-systematic horizontal code blocks, or over the content of encoder input bits in the place of systematic horizontal code blocks. The interleaving may be bitwise or bit subset-wise. The retransmissions do not contain any of the original bits. In the decoder, soft decisions are produced, and nothing needs to be discarded; decoding will typically improve with each retransmission.

摘要： Systems and methods are disclosed for performing combined grant-free and grant-based UL resource allocation. In a particular embodiment, a network entity sends a first type of UL transmission resource assignment selected from two types of UL transmission resource assignment mechanisms to a UE for grant-free transmission and a second type of UL transmission resource assignment from two types of UL transmission resource assignment mechanism to a UE for grant based transmission. The network entity then receives a first data transmission from the UE for grant free transmission using an assigned transmission resource and a second data transmission from the UE for grant based transmission using an assigned transmission resources. Other embodiments pertain to changing the resource allocation scheme from grant free to grant based for a UE, or vice versa. Examples reasons for doing so may include HARQ re-transmissions.

摘要： Aspects of the present application provide methods and device for use in User Equipment (UE) cooperation. UE cooperation may include the cooperating UEs (CUEs) forwarding traffic to or from one or more target UEs (TUEs) with redundant signal transmissions or receptions. Methods involve a base station transmitting configuration information to at least one cooperative user equipment (CUE) and to a target user equipment (TUE). The configuration information includes an indication of resources for a sidelink (SL) transmission and a redundancy parameter for the SL transmission. The SL transmission is a transmission for the at least one CUE to forward a packet intended for the TUE. The base station also transmits the packet intended for the TUE, to a plurality of UEs comprising the at least one CUE and the TUE.
