A determination is made of a second uplink BWP for transmission of a second preamble for the random-access procedure. The determination is based on not receiving, via a first downlink BWP associated with the first uplink BWP, a random-access response corresponding to the first preamble. Based on the determination of the second uplink BWP, the first downlink BWP is switched to a second downlink BWP associated with the second uplink BWP. The second preamble is transmitted via the second uplink BWP. | 2021-12-30 |
20210409171 | Carrier Aggregation - According to an example aspect of the present invention, there is provided an apparatus including at least one processing core, at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to obtain an uplink transmission configuration including information on at least one secondary cell candidate frequency, transmit a signal in the uplink in accordance with the uplink transmission configuration on the at least one secondary cell candidate frequency, during a connection establishment procedure which transitions the apparatus from an idle mode to a connected mode, and receive a resource aggregation configuration from a network. | 2021-12-30 |
20210409172 | ENHANCED RESOURCE ALLOCATION FOR WIRELESS COMMUNICATIONS - This disclosure describes systems, methods, and devices related to allocating non-continuous resource units (RUs). A device may determine a non-continuous RU allocation for one or more devices in a 80 MHz bandwidth including four 20 MHz channels, the non-continuous RU allocation including disabled tones of a 20 MHz channel of the four 20 MHz channels, and the disabled tones being a subset of tones within the 20 MHz channel. The device may determine a high efficiency wireless frame comprising an indication of the non-continuous RU allocation. The device may send the high efficiency wireless frame to one or more multiple devices. | 2021-12-30 |
20210409173 | Collision Handling of Reference Signals - A user equipment (UE) can include processing circuitry configured to decode control information of a physical downlink control channel (PDCCH) received via a resource within a control resource set (CORESET) occupying a subset of a plurality of OFDM symbols within a slot. At least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a PDSCH. The DM-RS can be detected within the slot, the DM-RS starting at a symbol location that is shifted from the pre-defined symbol location and following the subset of symbols. Downlink data scheduled by the PDCCH and received via the PDSCH can be decoded, where the decoding is based on the detected DM-RS. | 2021-12-30 |
20210409174 | METHOD AND DEVICE FOR REPORTING CHANNEL STATE IN WIRELESS COMMUNICATION SYSTEM - A method for reporting a channel state in a wireless communication system according to an embodiment of the present disclosure may comprise the steps of: receiving a channel state report setting including an index of a first bandwidth part (BWP); receiving a trigger of a channel state report for a second BWP other than the first BWP; measuring a channel state in the second BWP in a measurement gap according to the trigger; and transmitting the measured channel state to a base station on an available uplink resource within a first activated BWP after the measurement gap. | 2021-12-30 |
