Description

Method for processing bandwidth part, terminal and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, a terminal, and a network device for processing a bandwidth portion.

Background

In a New Radio (NR) system, a cell supports a system bandwidth of 400MHz at maximum, which is much larger than a system bandwidth of 20MHz supported by Long Time Evolution (LTE) at maximum, so that the NR system can support greater system and user throughput. However, supporting such a large system bandwidth would be a great challenge for the implementation of the terminal, and is not favorable for the implementation of the low-cost terminal. Therefore, to achieve dynamic and flexible bandwidth allocation of the NR system, the system bandwidth may be divided into a plurality of bandwidth parts (BWPs) to support access of the narrowband terminal or the terminal in the power saving mode.

Meanwhile, NR cells also support different resource configurations (Numerology) configured at different bandwidths, and if a terminal cannot support all Numerology of a cell, it may avoid configuring a corresponding frequency band to the terminal when configuring BWP for the terminal. Specifically, the network device may configure a BWP set available to each cell for the terminal through Radio Resource Control (RRC) signaling, and dynamically switch the BWPs to be started through layer one (L1) signaling, that is, activate one BWP and deactivate the currently activated BWP.

In addition, the terminal may initialize a Random Access process on the activated BWP, specifically, after determining the current activated BWP, the terminal determines an SSB according to the measurement result of the Synchronization Signal Block (SSB) detected on the activated BWP, and further determines a PRACH allocation according to the association between the SSB and the transmission timing of the Physical Random Access Channel (PRACH allocations), and simultaneously selects an available preamble (preamble), thereby completing resource selection for Random Access. However, for a scenario in which multiple BWPs are activated simultaneously, that is, a scenario in which a terminal supports activation of multiple BWPs, how the terminal flexibly manages the activated BWPs becomes a problem to be solved urgently.

Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a terminal Device or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network device 12 may be a Base Station or a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, it should be noted that, in the embodiment of the present invention, only the Base Station in the NR system is taken as an example, but does not limit the specific type of base station.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication links in a wireless communication system may comprise an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 11 to network device 12) or a Downlink for carrying Downlink (DL) transmissions (e.g., from network device 12 to terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

The method for processing the bandwidth part of the embodiment of the invention is applied to a terminal, and as shown in fig. 2, the method comprises the following steps:

step 21: deactivating at least one of the activated BWPs if the number of activated bandwidth parts BWPs reaches the maximum number of BWPs activated.

Wherein, the maximum active BWP number is used to indicate how many active BWPs the terminal is allowed to simultaneously, and the value of the maximum active BWP number may be predefined, configured by the network device, or the maximum value of the number of BWPs supported by the terminal, or the maximum value of the number of BWPs supported by the network device. The terminal supports the active BWP to be deactivated autonomously, so that the flexible management of the BWP can be realized. For example, for a terminal whose activated BWP number reaches the maximum BWP activation number, if the BWP carrying a specific service needs to be activated, the terminal may select at least one BWP among the activated BWPs to deactivate, so that a new BWP may be activated, thereby implementing flexible management of the BWP of the terminal.

Step 22: transmitting indication information indicating the deactivated at least one BWP.

Since deactivating BWP is an autonomous behavior of the terminal, in order to ensure the terminal and the network device to understand consistency, the terminal sends an indication information to the network device, where the indication information is used to indicate at least one BWP deactivated by the terminal. For example, the indication information carries identification information of the deactivated at least one BWP.

Wherein, step 21 may further include: and under the condition that the number of the activated bandwidth parts BWP reaches the maximum activated number of BWP, deactivating at least one of the activated BWPs if no physical random access channel PRACH resource is configured for the activated BWP. For example, for a scenario where a plurality of BWPs are simultaneously activated, if the number of BWPs activated by a terminal has reached the maximum number of BWPs activated, and none of the BWPs activated has PRACH resources, if BWPs configured with PRACH resources need to be activated, the terminal deactivates at least one BWP among the activated BWPs, so that BWPs configured with PRACH resources can be activated.

Wherein, before step 21, the method may further comprise: the maximum activation number of BWPs of the terminal is acquired. The acquisition method includes but is not limited to:

the method comprises the steps of firstly, receiving terminal configuration information configured by network equipment; the maximum activation number of BWPs is obtained from the terminal configuration information. In this way, the network device configures the maximum active BWP number for each terminal or terminal group. That is, the method is configured by the network per UE.

And secondly, determining the maximum active number of the BWP of the terminal according to the terminal capability. The maximum active BWP number is the smaller of the maximum BWP number supported by the network device to which the terminal belongs and the maximum BWP number supported by the terminal. The mode is an implicit configuration mode, and the value of the maximum BWP activation number is min { the maximum BWP number supported by the network device and the maximum BWP number supported by the terminal capability }.

In addition to the above, the maximum activation number of the BWP of the terminal may be defined in a protocol predefined manner.

In the above, how the terminal deactivates the activated BWPs and how the terminal obtains the maximum activation number of the BWPs are described, the following embodiment further describes how the terminal reports the deactivated at least one BWP to the network device after deactivating the at least one BWP in the activated BWPs. The reporting modes include, but are not limited to, the following:

in this way, the terminal carries the indication information in an uplink message (e.g. message 3 or Msg3) of a random access procedure (or referred to as RACH procedure) to notify the network device side.

Or, the indication information is carried in the Uplink information after the random access procedure is completed, in this manner, the terminal carries the indication information in the Uplink information after the RACH procedure is successfully completed to notify the network device side, for example, after the random access procedure is completed, the indication information is carried in the Uplink information carried in a Physical Uplink Control Channel (PUCCH).

It should be noted that, no matter the above carrying manner is adopted, for example, no matter the indication information is carried in the uplink message in the random access procedure or in the uplink information after the random access procedure is completed, the indication information may directly indicate to deactivate the BWP id of the BWP. The signaling format of the indication information may be implemented by referring to the following manner: the indication information is carried in a Control Element (CE) and/or a Logical Channel Identity (LCID) field of a Medium Access Control (MAC) Control Element (CE). This means that the indication information can be carried by the MAC CE or by a dedicated LCID field. For example, indicating in the MAC CE by means of bitmap (bitmap), such as indicating the ascending order of BWP identifiers (id) from left to right, 0 indicating the terminal-determined deactivated BWP, 1 indicating the BWP that remains activated; or 1 represents terminal-determined deactivated BWP, and 0 represents BWP remaining activated; or 1 indicates terminal-determined deactivation BWP, 0 can be ignored; or 0 indicates terminal-determined deactivation BWP, and 1 can be ignored. In addition, in the MAC CE, the deactivated BWP id may be represented by n bits, multiple BWP ids may be indicated, arranged in bytes, and the unused position is used as a reserved bit, and the MAC CE is indicated by using the newly added dedicated LCID to indicate the deactivation of BWP. Or adding a plurality of special LCID fields, which respectively represent the deactivation of a BWP.

Furthermore, the indication information may also indicate the BWP identity for deactivating BWP by means of an implicit indication, for example, the indication information is indicated by a preamble (preamble) or a preamble group. Pre-configuring preamble 1 or preamble group 1 represents BWP1 being deactivated, and so on; or pre-configuring the preamble k or group k of preambles represents that some BWPs are deactivated, and so on. The pre-configuration referred to herein may be pre-defined or network device configured.

In addition, it is worth pointing out that the terminal may also autonomously select a BWP to be activated from a BWP set configured by the network device, and report identification information of the autonomously activated BWP to the network device, where the reporting process may multiplex a reporting process indicating that the indication information of the BWP is deactivated, or may report the indication information separately, and the reporting mode may be the same as or different from the reporting mode of the indication information, and is not described herein again.

In the method for processing the bandwidth part of the embodiment of the invention, the terminal can autonomously deactivate certain BWPs, thereby improving the configuration flexibility of the terminal for activating the BWPs more, and meeting different service requirements.

The foregoing embodiments describe the processing method of the bandwidth part in different scenarios, and the following describes a terminal corresponding to the foregoing embodiments with reference to the accompanying drawings.

and the processing submodule is used for deactivating at least one of the activated bandwidth parts (BWPs) if the activated BWPs are not configured with Physical Random Access Channel (PRACH) resources under the condition that the number of the activated BWPs reaches the maximum activated number of the BWPs.

Wherein, the indication information is carried in the uplink message in the random access process; or, the indication information is carried in the uplink information after the random access procedure is completed.

The indication information is carried in a Media Access Control (MAC) Control Element (CE) and/or a Logical Channel Identity (LCID) field.

Wherein, the indication information is indicated by a preamble or a preamble group.

The above embodiment describes the method for processing the bandwidth part of the present invention from the terminal side, and the following embodiment further describes the method for processing the bandwidth part of the network device side with reference to the drawings.

As shown in fig. 5, the method for processing a bandwidth part according to an embodiment of the present invention is applied to a network device, and includes the following steps:

step 51: indication information indicating the deactivated at least one BWP is received.

Wherein the indication information is generated by the terminal after deactivating at least one of the activated bandwidth parts BWPs, if the number of the activated BWPs reaches the maximum activation number of BWPs.

Wherein, the maximum active BWP number is used to indicate how many active BWPs the terminal is allowed to simultaneously, and the value of the maximum active BWP number may be predefined, configured by the network device, or the maximum value of the number of BWPs supported by the terminal, or the maximum value of the number of BWPs supported by the network device. Since deactivating BWP is an autonomous behavior of the terminal, in order to ensure the terminal and the network device to understand consistency, the terminal sends an indication information to the network device, where the indication information is used to indicate at least one BWP deactivated by the terminal.

Step 52: and determining the BWP deactivated by the terminal according to the indication information.

The indication information is generated by the terminal according to the autonomously deactivated BWP, and can indicate the deactivated BWP of the terminal, so that the network device does not use the deactivated BWP any more after determining the autonomously deactivated BWP of the terminal according to the indication information, thereby avoiding the problem that the deactivated BWP cannot normally receive the information, and ensuring reliable information transmission.

Before step 51, further comprising: sending terminal configuration information; wherein the terminal configuration information is used to indicate a maximum number of BWPs activated. In this way, the network device configures the maximum active BWP number for each terminal or terminal group. That is, the method is configured by the network per UE. It is noted that before sending the terminal configuration information, the network device may also configure the terminal configuration information for each terminal or terminal group separately.

The reporting mode of the indication information may include, but is not limited to: the indication information is carried in the uplink message in the random access process; or, the indication information is carried in the uplink information after the random access procedure is completed. The indication information may be carried in the MAC control element CE and/or the logical channel identity LCID field. Alternatively, the indication information may also be indicated by a preamble or a preamble group.

Wherein, before step 51, the method further comprises: configuring a preamble or preamble group to indicate BWP, e.g., pre-configuring preamble 1 or preamble group 1 to represent BWP1 deactivated, and so on; or pre-configuring the preamble k or group k of preambles represents that some BWPs are deactivated, and so on.

In the method for processing the bandwidth part of the embodiment of the present invention, the terminal may autonomously deactivate some BWPs, so as to improve the flexibility of configuring the terminal with multiple activated BWPs, so as to meet different service requirements.

The foregoing embodiments respectively describe in detail the processing methods of the bandwidth parts in different scenarios, and the following embodiments further describe the corresponding network devices with reference to the accompanying drawings.

As shown in fig. 6, a network device 600 according to an embodiment of the present invention can implement details of an indication information method for receiving at least one BWP indicating deactivation according to an embodiment of the present invention, and achieve the same effects; wherein, the indication information is generated after the terminal deactivates at least one of the activated bandwidth parts BWPs when the number of the activated bandwidth parts BWPs reaches the maximum activation number of BWPs, and the network device 600 specifically includes the following functional modules:

a receiving module 610 for receiving indication information indicating deactivated at least one BWP; wherein the indication information is generated by the terminal after deactivating at least one of the activated bandwidth parts BWPs when the number of the activated BWPs reaches the maximum activation number of BWPs;
