This invention relates to a proposal of an uplink resource assignment format and a downlink resource assignment format. Furthermore, the invention relates to the use of the new uplink/downlink resource assignments in methods for (de)activation of downlink component carrier(s) configured for a mobile terminal, a base station and a mobile terminal. To enable efficient and robust (de)activation of component carriers, while minimizing the signaling overhead, the invention proposes a new uplink/downlink resource assignment format that allow the activation/deactivation of individual downlink component carriers configured for a mobile. The new uplink or downlink resource assignment comprises an indication of the activation state of the configured downlink component carriers, i.e., indicate which downlink component carrier(s) is/are to be activated or deactivated. This indication is for example implemented by means of a bit-mask that indicates which of the configured uplink component carriers are to be activated respectively deactivated.

Examples described herein relate to managing communications on a first subscription and a second subscription of a multi-Subscriber Identity Module (SIM) wireless communication device via a Radio Frequency (RF) resource, including, but not limited to, tuning the RF resource away from the second subscription to the first subscription, detecting a network-set activation state of a secondary cell associated with the first subscription, and adjusting the activation state of the secondary cell based on the network-set activation state.

Methods, systems, and devices for wireless communication are described. A transmitting device may select an orthogonal metric based at least in part on at least one of each direction of a plurality of directions to transmit millimeter wave discovery signals or a location parameter associated with the transmitting device. The transmitting device may transmit, in the each direction of the plurality of directions, the millimeter wave discovery signals, where the each transmitted millimeter wave discovery signal has a different orthogonal metric applied that was selected based at least in part on the at least one of the each direction or the location parameter.

A wireless device receives a radio resource control (RRC) reconfiguration message triggering a first active bandwidth part (BWP) switching of a first cell. Based on the triggering the first active BWP switching during a second active BWP switching of a second cell, the first active BWP switching is delayed until the second active BWP switching is completed.

A wireless device receives configuration parameters comprising a value for a bandwidth part inactivity timer. Downlink control information, indicating a resource assignment, is received on a primary cell. The bandwidth part inactivity timer of an active bandwidth part of the primary cell is started in response to determining that no random access procedure is ongoing on a secondary cell. A switch from the active bandwidth part to a default bandwidth part is made in response to an expiry of the bandwidth part inactivity timer.

A radio station (2) transmits configuration information (501) to a radio terminal (1). The configuration information (501) indicates, on a cell-by-cell basis, at least one specific cell on which the radio terminal (1) is allowed to perform at least one of data transmission and data reception on a radio bearer used for uplink transmission or downlink transmission or both via a common Packet Data Convergence Protocol (PDCP) layer (402). As a result, in a radio architecture that provides tight interworking of two different Radio Access Technologies (RATs), it is for example possible to allow an eNB to indicate, to a radio terminal (UE), a specific cell on which the UE should perform uplink transmission.

A wireless device receives configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups comprising a primary PUCCH group comprising a primary cell, and a secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH. The wireless device receives, during a first time interval, a first indication to activate a secondary cell of the primary PUCCH group. The wireless device starts transmission of channel state information of the secondary cell from a second time interval that is pre-determined number of time intervals after the first time interval. The wireless device receives, during a third time interval, a second indication for activation of the PUCCH secondary cell, and starts transmission of channel state information for the PUCCH secondary cell from a fourth time interval that is a number of time intervals after the third time interval.

In one aspect, a method of wireless communication includes receiving, by a wireless communication device during a slot, first data according to a first resource bandwidth (RBW) configuration of a bandwidth part (BWP) configuration, where the BWP configuration is configured for uplink and downlink operations. The method further includes transmitting, by the wireless communication device during the slot, second data according to a second RBW configuration of the BWP configuration, where the second RBW configuration is different from the first RBW configuration. Other aspects and features are also claimed and described.

Aspects relate to wireless communication using multiple active bandwidth parts (BWPs). For example, a base station may configure a user equipment (UE) with two or more active BWPs. In some examples, the base station may send scheduling information to the UE on one active BWP, where the scheduling information schedules a communication on one or more active BWPs.

Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable mediums for indicating carrier pairings in supplemental uplink (SUL) communications. A method that may be performed by a user equipment (UE) generally includes determining carrier groupings for SUL communications supported by the UE, each carrier grouping comprising at least one component carrier (CC) carried in an SUL band and at least one CC carried in a non-supplemental uplink (NSUL) band and providing signaling indicating the carrier groupings for a combination of at least three CCs jointly carried in at least one SUL band and at least one NSUL band.
