A user equipment is provided with puncturing information indicating a resource to which downlink data is punctured among time-frequency resources to which the downlink data is allocated. The user equipment may decode the downlink data received in the time-frequency resource on the basis of the puncturing information. The downlink data may be mapped to the time-frequency resource by a combined method of a time-first resource mapping method and a frequency-first resource mapping method, or by a distributed resource mapping method.

Different sets of downlink control information (DCI) fields may be configured for DCI that includes an indication to trigger bandwidth part switching at a user equipment (UE). For example, a UE may receive DCI that triggers the UE to switch operation from a first bandwidth part to a second bandwidth part. The UE may also identify a set of transformable DCI fields and a set of non-transformable DCI fields within the DCI. The UE may then determine updated content of the DCI for application to the second bandwidth part based on whether DCI fields are included in the set of transformable or the set of non-transformable fields. In some cases, the UE may identify a null assignment in the received DCI and may switch its operation from the first bandwidth part to the second bandwidth part based on the null assignment.

This application provides a method and apparatus for obtaining a resource indication value. The method includes: a terminal receives downlink control information, which includes a resource indication value determined based on a first bandwidth part and indicates a data channel occupying contiguous virtual resource blocks in a second bandwidth part, and sends or receives the data channel, wherein a number RB.sub.start identifying the starting virtual resource block of the contiguous virtual resource blocks, a quantity L.sub.RBs of the contiguous virtual resource blocks, and the resource indication value RIV satisfy following relation: RB.sub.start=└K.Math.RB′.sub.start┘, and L.sub.RBs=└K.Math.L′.sub.RBs┘, wherein K is a positive number and satisfies K≤└N.sub.RB.sup.BWP2/N.sub.RB.sup.BWP1┘, N.sub.RB.sup.BWP1 referring to a bandwidth of the first bandwidth part, and N.sub.RB.sup.BWP2 referring to a bandwidth of the second bandwidth part; and RIV=N.sub.RB.sup.BWP1(L′.sub.RBs−1)+RB′.sub.start when (L′R.sub.RBs−1)≤└N.sub.RB.sup.BWP1/2┘, or RIV=N.sub.RB.sup.BWP1(N.sub.RB.sup.BWP1−L′.sub.RBs+1)+(N.sub.RB.sup.BWP1−1−RB′.sub.start) when (L′.sub.RBs−1)>└N.sub.RB.sup.BWP1/2┘

A base station may perform online calibration of antenna elements at two or more transmission reception points (TRPs) based on measurements by one or more user equipment (UEs). The base station may transmit a request for the one or more UEs to perform antenna calibration measurements, for the two or more TRPs, during measurement gaps. The base station may coordinate, among the two or more TRPs, transmission of reference signals during the measurement gaps. The base station may receive a report based on the antenna calibration measurements from the one or more UEs. The base station may calibrate one or more antenna elements of the two or more TRPs based on the antenna calibration measurements.

A base station may configure a Doppler tracking sounding reference signal (SRS) resource set with different time gaps between SRS resources of the Doppler tracking SRS resource set. However, factors influencing an optimal time gap for uplink Doppler parameter estimation may change over time and may depend on a Doppler parameter to be estimated. Therefore, parameters of an aperiodic Doppler tracking SRS resource set configuration may become suboptimal for estimating uplink Doppler parameters. Some techniques and apparatuses described herein enable dynamic parameter adaptation for aperiodic Doppler tracking SRS resource sets. The base station may dynamically adapt one or more parameters for an aperiodic Doppler tracking SRS resource set to modify a time gap and/or a number of resources or symbols to be transmitted for an aperiodic Doppler tracking SRS resource set. The base station may transmit downlink control information that indicates the one or more parameters.

Arrangement for switching between an active bandwidth part and the target bandwidth part are disclosed. A method includes selecting one or more resource blocks comprised in the target bandwidth part for a transmission or reception between the wireless device and the network node. The selected resource blocks to be used in the target bandwidth part are indicated in a resource allocation field of a downlink control channel information in the active bandwidth part. The allocation field includes information bits and the resource allocation field in the active bandwidth part and the information bits are configured based on a target bandwidth part resource allocation type. The target bandwidth part resource allocation type indicates whether the information bits have a bitmap corresponding to one or more resource block groups or an integer value corresponding to a starting resource block and a length of the allocation in resource blocks.

Aspects relate to switching between different search space set groupings. A base station (BS) may send an indication to a user equipment (UE) to instruct the UE to switch from a first search space set grouping (SSSG) to a second SSSG. For example, the BS may send this indication after the BS transmits a first data burst to the UE. In some examples, the UE may then switch back to the first SSSG upon expiration of a timer. For example, the BS may configure the UE with a timer value (e.g., an absolute value, a relative value, or an indication thereof) that the UE may use to determine when to switch back to the first SSSG to receive a second data burst from the base station. In some examples, the UE may switch back to the first SSSG based on a discontinuous reception duration.

Systems and methods are disclosed herein that relate to transmitting and receiving a transmission when there is a collision between the transmission and reserved resource elements. In some embodiments, a radio access node for a cellular communications network is disclosed, wherein the radio access node comprises a transceiver, a processor, and memory storing instructions executable by the processor whereby the radio access node is operable to transmit, via the transceiver, a downlink transmission to a wireless device using one or more Physical Resource Blocks (PRBs) that comprise reserved Resource Elements (REs) by puncturing the downlink transmission at positions of the reserved REs. In some embodiments, the downlink transmission is an Enhanced Physical Downlink Control Channel (EPDCCH) transmission or a Physical Downlink Shared Channel (PDSCH) transmission. Further, in some embodiments, the reserved REs are REs utilized for one or more CSI-RSs.

A communication device includes a receiver, a transmitter and a control circuit. The receiver is configured to receive, from an infrastructure equipment of a mobile communications network, downlink signals on a downlink via a wireless access interface of the mobile communications network. The transmitter is configured to transmit, to the infrastructure equipment, uplink signals on an uplink via the wireless access interface. The control circuit is configured to control the receiver to receive the downlink signals and control the transmitter to transmit the uplink signals. The control circuit is further configured to delay a reception period for the receiver to receive the downlink signals after a transmission period in which the transmitter transmits the uplink signals when a duration of the transmission period exceeds a predetermined threshold.
