Description

APPARATUS AND METHOD OF WIRELESS COMMUNICATION

BACKGROUND OF DISCLOSURE

1. Field of the Disclosure

[0001] The present disclosure relates to the field of communication systems, and more particularly, to an apparatus and a method of wireless communication, which can provide a good communication performance and/or high reliability.

2. Description of the Related Art

[0002] Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multipleaccess systems include fourth generation (4G) systems such as long term evolution (LTE) systems, LTE-advanced (LTE-A) systems, or LTE-A pro systems, and fifth generation (5G) systems which may be referred to as new radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include a number of base stations or network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as user equipment (UE).

[0003] In third generation partnership project (3GPP) new radio (NR) systems, a network may provide a radio resource control (RRC) configuration for an operation, the RRC configuration is normally compatible with the network structure, such as a bandwidth size, a number of antenna ports, antenna chains, etc. In future systems, operators may be intent to reduce a power consumption, therefore, the network structure may need to be adapted/adjusted from time to time, leading, based on a legacy system configuration, to an RRC reconfiguration or a system information update.

[0141] Example:

[0142] FIG. 4 illustrates an example of a wireless communication method according to an embodiment of the present disclosure. In some examples, FIG. 4 illustrates that, the wireless communication method includes a step S401, a UE is configured with a CSI report configuration and one or more CSI resource configurations, the CSI resource configuration may include a first parameter, and the first parameter may be configured to have a first configuration and a second configuration and a step S402, the UE needs to determine when to use the first configuration and when to use the second configuration. In some optional examples, the CSI report configuration is associated with the one or more CSI resource configurations. The CSI resource configuration may include a first parameter, which is used to configure at least one of the followings: a BWP, a number of antenna ports, a power control offset, or a CSI-RS resource mapping. In some optional examples, when the first parameter is relevant to the number of antenna ports, the first configuration may correspond to a first number of antenna ports, and the second configuration may correspond to a second number of the antenna ports. In some optional examples, there is an initial configuration, the initial configuration may be the first configuration or the second configuration, or the initial configuration may be pre-defined or configured by the network such as the base station. If the initial configuration is the first configuration, the network may trigger the UE to switch from the first configuration to the second configuration.

[0143] In some optional examples, the switch between the first configuration and the second configuration may be relevant to a trigger signal from the network, or a time period configured by the network. When the switch is relevant to a trigger signal, the network may use a DCI or an MAC-CE to trigger the UE to switch from the first configuration to the second configuration or from the second configuration to the first configuration. In some optional examples, when a DCI format is used to trigger the switch from the first configuration to the second configuration, the DCI format may be CRC scrambled with a RNTI value, where the RNTI value is group-common to a group of UEs. Moreover, the switch location may be relevant to the location where the UE receives the DCI format.

[0144] FIG. 5 illustrates an example of a wireless communication method according to an embodiment of the present disclosure. In some examples, FIG. 5 illustrates that, the wireless communication method includes a step S501, a UE receives an activation signal from the network such as the base station to activate periodic and/or semi-persistent CSI measurement and/or feedback, a step S502, after activation, the periodic and/or the semi-persistent CSI measurement and/or feedback follow the initial CSI reporting and/or CSI measurement configuration, a step S503, the UE receives a trigger signal, and a step S504, after the UE receives the trigger signal, the UE continues performing the periodic and/or the semi-persistent CSI measurement and/or feedback following the second configuration. In some optional examples, the activation may be done by an RRC signaling, an MAC-CE, or a DCI. In some optional examples, the initial CSI reporting and/or CSI measurement configuration is the first configuration.

[0145] In the following, an example for CSI resource configuration is disclosed. The CSI resource configuration is configured by an IE.

[0146]

[0147] The IE contains a resourceMapping parameter, which is further configured by another IE CSI-RS- ResourceMapping and in this IE, the network may configure the number of the antenna ports, i.e., using parameter nrofPorts. In some examples, the network may configure two different values or nrofPorts, e.g., pl (one port) and p2 (two ports), pl is considered as the first configuration and p2 is considered as the second configuration. The initial configuration may be predefined as the first configuration, or the network may also configure the initial configuration in the IE. Other IES can also be applied to the above examples, and the present invention is not limited to this.

[0148] IE CSI-RS-ResourceMapping:

[0149] FIG. 6 illustrates an example of a wireless communication method according to an embodiment of the present disclosure. In some examples, FIG. 6 illustrates that, the wireless communication method includes that: for periodic CSI feedback, when the UE is configured by the network about the NZP-CSI-RS-Resource, the UE may apply the initial configuration (in some examples, the number of antenna ports being pl), until the UE receives a trigger signal from the network and then the UE may change to the second configuration (the number of antenna ports being p2).

[0150] It is to note that similar method can also be applied on other configuration parameters, such as powerControlOffset, or powerControlOffsetSS, where the power control offset can be configured with two values, one corresponding to the first configuration and the other corresponds to the second configuration. A trigger signal from the network may be used to trigger the change from the first configuration to the second configuration. In some examples, the change between two configurations may be implemented in other ways. For example, the RRC signaling only configure one configuration, using previous example of NZP-CSI-RS-Resource IE, the nrofPorts can be configured with only one value corresponding to the first configuration or the initial configuration. The second configuration is explicitly or implicitly provided in the trigger signal. The way of explicit indication may be that the trigger signal provides a configuration value for the second configuration. The implicit way may be that the second configuration is derived based on the first configuration and a parameter given in the trigger signal. The parameter may be a scaling factor and the second configuration value is derived from the scaling factor based on the first configuration value. In previous example, the second configuration of the number of antenna port (p2) is a scaled number of the number of antenna port configured by the first configuration (pl). Other RRC configurations can similarly apply the above methods, and the examples do not repeat here.

[0151] In some optional examples, the trigger signal and/or the time period is relevant to a cell identifier (ID) indicating a cell where the UE is located, and the trigger signal and/or the time period is relevant to the switch between the first configuration and the second configuration by the UE in the cell. For example, a bit value is used to indicate whether to switch between the first configuration and the second configuration. When the bit is equal to 1, it indicates the switch between the first configuration and the second configuration, and when the bit is equal to 0, it indicates no switch between the first configuration and the second configuration. In another example, when the bit is equal to 0, it indicates the switch between the first configuration and the second configuration, and when the bit is equal to 1, it indicates no switch between the first configuration and the second configuration. In some optional examples, the trigger signal and/or the time period is relevant to a configuration index, and the configuration index corresponds to the first configuration or the second configuration.

[0152] FIG. 7 illustrates an example of a wireless communication method according to an embodiment of the present disclosure. In some examples, FIG. 7 illustrates that, the wireless communication method includes a step S701, when a time period is used for the switch between the first configuration and the second configuration, the network may configure a time period and a step S702, the UE uses the first configuration or the second configuration within the time period. Optionally, the UE uses the second configuration or the first configuration when the time period ends. The network may explicitly configure the start of the time period and/or the length of the time period and/or the end of the time period. Optionally, the time period may be periodic or semi-persistent. In some examples, the start of the time period may be relevant to the trigger signal as described above. [0153] Similar method can also be used to configure BWP. In the legacy system, a BWP ID corresponds to a configured BWP size and location in the frequency domain for downlink (DL) and/or uplink (UL). In some examples, a same BWP ID can be configured with a first configuration and a second configuration, where the first configuration configures a first BWP size and/or location and the second configuration configures a second BWP size and/or location.

In some examples, FIG. 8 illustrates that, the wireless communication method includes a step S801, when the UE receives the trigger signal, the delay period starts from a location relevant to the received trigger signal and a step S802, after the delay period, the UE apples the changed configuration.

[0155] In some optional examples, the location may be the start or the end of the slot in which the trigger signal is received. In some optional examples, the delay period length is relevant to at least one of the followings: a processing time, a BWP switching delay, or a beam switching delay. In some examples, during the switching delay, the UE does not need to perform a DL reception, an UL transmission, a CSI measurement, and/or a CSI reporting, where the DL reception includes at least one of the followings: a PDSCH reception, a PDCCH reception, an SSB reception, or a CSI-RS reception. The UE transmission includes at least one of the followings: a PUSCH transmission, a PUCCH transmission, a PRACH transmission, or an SRS transmission.

[0156] In some examples, the trigger signal may be a PDCCH carrying a DCI format. The DCI format is a group- common DCI, and the DCI format is CRC scrambled with a RNTI value, where the RNTI value is configured in the RRC signaling. In some examples, the RNTI value is common to a group of UE. The DCI format contains an indication field, and the indication field is used to signal the configuration switch. In some examples, the indication field indicates a first value or a second value, where the first value corresponds to the first configuration and the second value corresponds to the second configuration.
