  • Publication number: 20240155588
    Abstract: Embodiments include a communication system including host computer, base station, and UE, and methods therein. The host computer provides user data and initiates a transmission carrying the user data to the UE via a cellular network comprising the base station. The UE receives, from the base station, an indication of an active bandwidth part (BWP), which is of size NBWP,1size in number of frequency-domain resource blocks (RBs). The UE receives an indication of one or more frequency-domain RBs assigned within the active BWP for carrying the user data. The indication is encoded based on a size NBWP,2size (<size NBWP,1size) of another BWP than the active BWP. The UE decodes the indication to obtain a starting virtual RB and a length of contiguously allocated RBs within the active BWP. The starting virtual RB is encoded with resolution K RBs, with K being based on a ratio of sizes NBWP,1size and NBWP,2size.

  • Publication number: 20240146586
    Abstract: Embodiments herein disclose e.g. a method performed by a wireless device (10) for handling communication for the wireless device in a second wireless communication network. The second wireless communication network coexists with a first wireless communication network on a same bandwidth in frequency, wherein the first wireless communication network applies a first shift in frequency in uplink transmissions. The wireless device receives from a radio network node (12, 13), an indication indicating application of a second shift in frequency to uplink transmissions in case the second wireless communication network uses Frequency Division Duplex (FDD). The wireless device further applies the second shift in frequency to uplink transmissions, wherein the second shift defines a shift in frequency to a subcarrier relative to a subcarrier grid of the second wireless communication network or a shift in frequency to the subcarrier grid of the second wireless communication network.

  • Patent number: 11956730
    Abstract: A system and method for determining a Physical Uplink Control Channel (PUCCH) power control parameter h(nCQI,nHARQ) for two Carrier Aggregated (CA) PUCCH formats—PUCCH format 3 and channel selection. The value of h(nCQI,nHARQ) may be based on only a linear function of nHARQ for both of the CA PUCCH formats. Based on the CA PUCCH format configured for the User Equipment (UE), the e-Node B (eNB) may instruct the UE to select or apply a specific linear function of nHARQ as a value for the power control parameter h(nCQI,nHARQ), so as to enable the UE to more accurately establish transmit power of its PUCCH signal. Values for another PUCCH power control parameter—?F_PUCCH(F)—are also provided for use with PUCCH format 3. A new offset parameter may be signaled for each PUCCH format that has transmit diversity configured.

  • Patent number: 11943773
    Abstract: In New Radio, NR, when a SR PUCCH resource to which a triggered SR is mapped overlaps with a PUCCH carrying UCI, such as HARQ-ACK and/or CSI, an indication of the corresponding schedulingRequestID, which determines the logical channel ID with new data, is directly encoded in the UCI. That is, rather than directly transmit the relevant SR PUCCH resource(s), which indirectly identifies the SR ID, an indication of the SR ID is directly transmitted on the PUCCH transmission. The encoding of an indication of SR ID may comprise adding bits to UCI to be transmitted, for PUCCH formats 2, 3, or 4. For PUCCH format 0, encoding the indication of SR ID comprises adding an initial cyclic offset indicating the triggered SR.
