Description
Technical Field
Embodiments of the present invention relate to the field of communications, and in particular, to a method, a base station, a user equipment and a readable medium for indicating and configuring BWP parameters.
Background
In a New Radio (NR) system, the maximum channel bandwidth of each carrier is 400MHz, which far exceeds the 20MHz bandwidth of a Long Term Evolution (LTE) system. When initially accessing, if a User Equipment (UE) directly accesses a 400MHz bandwidth, the hardware cost of the UE is high, and a large power consumption is also caused. The concept of fractional Bandwidth (BWP) is introduced. In an NR system, each cell may contain one or more BWPs, each of which occupies a limited bandwidth, wherein at least one BWP allows idle-state user equipments to camp on. The idle ue receives the system message and the paging message through the BWP, so that the access network establishes a Radio Resource Control (RRC) connection and a data Radio bearer. This BWP is referred to as the initial active BWP or default BWP. For the same user equipment, the base station may configure multiple BWPs for the user equipment according to the user equipment capability, service requirements, and the like. There may be at least one active BWP per user device.
For each BWP, a series of configuration parameters are corresponding, for example, a location parameter of an occupied Physical Resource block, and a Control Resource Set (CORESET) configuration parameter, a Physical Downlink Shared Channel (PDSCH) configuration parameter, an Uplink Physical Control (PUCCH) configuration parameter, a Physical Uplink Shared Channel (PUSCH) configuration parameter, a reference signal, a Random Access Channel (RACH) configuration parameter, and the like, where the user equipment can apply the BWP only after knowing the configuration parameters corresponding to the BWP.
When the base station needs to instruct the ue to configure multiple BWPs, completely indicating all parameters corresponding to BWPs currently causes a large signaling overhead, resulting in low spectrum efficiency.

Detailed Description
In the NR system, for each BWP, a series of configuration parameters, such as a location parameter of an occupied physical resource block, and a CORESET configuration parameter, a PDSCH configuration parameter, a PUCCH configuration parameter, an uplink physical shared channel PUSCH configuration parameter, a reference signal, an RACH configuration parameter, etc., are corresponding to each BWP, and the user equipment can apply the BWP only after knowing the configuration parameters corresponding to the BWP. When a plurality of BWPs need to be configured, completely configuring all parameters corresponding to the BWPs currently causes a large signaling overhead, resulting in low spectrum efficiency.
The embodiment of the invention only indicates the parameters with different values of the same name parameter corresponding to the benchmark BWP based on the benchmark BWP for the newly added BWP, and only indicates the parameters with changed values for the parameter value change of the existing BWP. Because all parameters corresponding to the BWP do not need to be completely indicated, but only parameters with different values or changed values need to be indicated, signaling overhead can be effectively reduced, and spectrum efficiency is improved.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides a method for instructing a user equipment to configure BWP parameters, where the method may include the following steps:
step S101, for the newly added BWP, only indicating the parameter with the same name corresponding to the reference BWP with a different value based on the reference BWP, so that the ue configures the BWP parameter according to the indication.
In a specific implementation, when the base station needs to perform operations such as reconfiguration, cell handover, etc. on the user equipment, the base station may instruct the user equipment to configure a new BWP. For the newly added BWP, if all the parameters corresponding to the newly added BWP are completely indicated, a large signaling overhead will be incurred, resulting in low spectrum efficiency. Therefore, the embodiment of the invention introduces the reference BWP, and only indicates the parameters with the same name corresponding to the reference BWP and different values of the parameters based on the reference BWP, so as to effectively reduce signaling overhead and improve spectrum efficiency.
In a specific implementation, the reference BWP may be set as an initial active BWP, i.e. a default BWP, or as a current active BWP, where the current active BWP may or may not be the same as the initial active BWP. The baseline BWP is valid for all new BWPs. I.e. any new BWP, can be indicated using the reference BWP.
In a specific implementation, if the reference BWP is set as the currently active BWP and there are multiple currently active BWPs in the cell, the reference BWP may be set as the currently lowest numbered active BWP or may be set as the currently highest numbered active BWP, which is not limited by the embodiment of the present invention.
In a specific implementation, the reference BWP may also be set to be a BWP having the same numerology attribute as the newly added BWP, where the numerology attribute is a set of parameters defined by the 5G system, and may include a subcarrier interval, a symbol length, a Cyclic Prefix (CP) length, etc. for identifying BWPs with different attributes. When the reference BWP is set to be the BWP having the same numeric attribute as the newly added BWP, the base station needs to indicate all parameters corresponding to the newly added BWP if the base station indicates that the user equipment has been instructed to configure the BWP having the same numeric attribute as the newly added BWP before the base station indicates the newly added BWP.
In a specific implementation, the reference BWP may also be explicitly indicated in the RRC signaling, that is, the reference BWP corresponding to the newly added BWP is indicated in the RRC signaling, if there are multiple newly added BWPs, a common reference BWP may be indicated, or the reference BWP corresponding to each newly added BWP may be individually indicated, which is not limited in the embodiment of the present invention.
In a specific implementation, the reference BWP may be one or more.
In an embodiment of the present invention, when the reference BWP corresponding to each new BWP is separately indicated by RRC signaling, there may be a plurality of reference BWPs.
In specific implementation, when the parameter value corresponding to the new BWP is different from the parameter value corresponding to the same name of the reference BWP, the difference between the parameter value corresponding to the new BWP and the parameter value corresponding to the same name of the reference BWP may be indicated to reduce bit overhead and improve spectrum efficiency; or directly indicate the complete value of the parameter with the same name and different value corresponding to the reference BWP, so as to save the processing overhead.
In an embodiment of the present invention, for a newly added BWP, it may be determined whether a parameter value corresponding to the newly added BWP is different from a parameter value corresponding to a reference BWP with the same name; and when the parameter value corresponding to the new BWP is different from the parameter value corresponding to the same name of the benchmark BWP, indicating the difference value of the parameter value and the parameter value corresponding to the same name of the benchmark BWP.
In another embodiment of the present invention, for an added BWP, it may first be determined whether a parameter value corresponding to the added BWP is different from a parameter value corresponding to a reference BWP with the same name; and when the parameter value corresponding to the new BWP is different from the parameter value corresponding to the benchmark BWP and having the same name, indicating the value of the parameter.
In an embodiment of the present invention, for example, the NR base station configures Cell 1, which has a bandwidth of 200MHz and includes 5 BWPs, sequentially BWP0 to BWP4, where BWP0 is the initial access BWP, the bandwidth is 10MHz, and its numerology attribute is 0 (corresponding to subcarrier spacing of 15 KHz). User equipment 1 first resides in Cell 1, and due to traffic demand, user equipment 1 initiates a random access procedure, establishes an RRC connection and a radio bearer through BWP 0. At this time, the user equipment 1 obtains all corresponding parameter configurations in BWP0, such as the position of the physical resource block occupied by BWP0, and the CORESET configuration, PDSCH configuration, PUCCH configuration, PUSCH configuration, reference signal configuration, RACH configuration, etc. therein. After some time, the base station instructs user equipment 1 to configure BWP1 and BWP3 based on the traffic demand of user equipment 1 and the capability needs of user equipment 1, where BWP1 has a numerology attribute of 0 (corresponding to subcarrier spacing of 15KHz) and BWP3 has a numerology attribute of 1 (corresponding to subcarrier spacing of 30 KHz). At this time, if all the parameters corresponding to BWP1 and BWP3 are completely indicated, a large signaling overhead is caused, resulting in low spectrum efficiency.
In order to reduce Signaling overhead, the base station introduces a reference BWP when indicating BWP1 and BWP3, and the user equipment is instructed to configure BWP1 and BWP3 by using the above Delta Signaling mechanism (i.e. only the parameter indicating the same name corresponding to the reference BWP takes a different value), as follows:
if the initial access BWP0 is selected as a reference, the base station needs to judge whether the values of the parameters corresponding to BWP1 and BWP3 are consistent with the value of the same parameter corresponding to BWP0, and if so, no indication is needed; if not, a complete value or difference of the parameter may be indicated. For example, for PDSCH partial parameters: a power value parameter of the reference signal, a parameter related to a power value of data transmitted on the PDSCH, and a parameter related to synchronization of the downlink received signal. If the value of the power value parameter of the reference signal corresponding to BWP1 is consistent with the value of the power value parameter of the reference signal corresponding to BWP0, the user equipment 1 may not indicate that the value of the power value parameter of the reference signal corresponding to BWP1 is obtained according to the reference BWP 0; and if the value of the power value parameter of the reference signal corresponding to the BWP1 is inconsistent with the value of the power value parameter of the reference signal corresponding to the BWP0, indicating the value of the power value parameter of the reference signal corresponding to the BWP 1. For the parameter related to the power value of the data transmitted on the PDSCH, if the value of the parameter related to the power value of the data transmitted on the PDSCH corresponding to BWP1 is consistent with the value of the parameter related to the power value of the data transmitted on the PDSCH corresponding to BWP0, the user equipment 1 may not indicate that the value of the parameter related to the power value of the data transmitted on the PDSCH is obtained according to the reference BWP 0; if the value of the parameter related to the power value of the data transmitted on the PDSCH corresponding to BWP1 is not consistent with the value of the parameter related to the power value of the data transmitted on the PDSCH corresponding to BWP0, the value of the parameter related to the power value of the data transmitted on the PDSCH corresponding to BWP1 is indicated. For the synchronization-related parameter of the downlink received signal, if the value of the synchronization-related parameter of the downlink received signal corresponding to BWP1 is consistent with the value of the synchronization-related parameter of the downlink received signal corresponding to BWP0, it may not indicate that the user equipment 1 obtains the value of the synchronization-related parameter of the downlink received signal corresponding to BWP1 according to the reference BWP 0; and if the value of the synchronization-related parameter of the downlink received signal corresponding to the BWP1 is inconsistent with the value of the synchronization-related parameter of the downlink received signal corresponding to the BWP0, indicating the value of the synchronization-related parameter of the downlink received signal corresponding to the BWP 1. BWP3 may also employ similar processing mechanisms and will not be described in detail herein.
If BWPs with the same numerology attribute are selected as the reference BWP, the base station may indicate the parameters corresponding to user equipment configuration BWP1 for BWP1 using the Delta Signaling mechanism described above (i.e., only parameters indicating that the same name corresponding to the reference BWP takes different values) since BWP0 and BWP1 have the same numerology attribute. For BWP3, the base station can only indicate all parameters for BWP3 since BWP0 has a different numerology attribute, no corresponding baseline BWP.
If BWP0 is explicitly indicated in the RRC Signaling as the reference BWP of BWP1 and BWP3, the base station may use the Delta Signaling mechanism to indicate the ue to configure the parameters corresponding to BWP1 and BWP3 when indicating the parameters corresponding to BWP1 and BWP 3.
Step S102, for the parameter value change of the existing BWP, only the parameter of the value change is indicated, so that the user equipment configures the BWP parameter according to the indication.
In a specific implementation, for a parameter value change of an existing BWP, only a parameter with a changed value may be indicated, and for a parameter with an unchanged value, the parameter does not need to be indicated again.
In specific implementation, for a parameter with a changed value, a difference between the value after the parameter is changed and the value before the parameter is changed may be indicated to save reporting bits and improve spectrum utilization, and the value after the parameter is changed may also be indicated to save processing overhead.
It is understood that the steps S101 and S102 are only used to limit two different sets of situations for instructing the user equipment to configure the BWP parameters, and do not limit the order of implementation. In a specific implementation, step S101 may be executed first, and then step S102 is executed, or step S102 may be executed first, and then step S101 is executed, or step S101 and step S102 are executed in parallel.
In an embodiment of the present invention, for example, after the base station instructs the user equipment to configure a plurality of active BWPs (including BWP0, BWP1 and BWP3) simultaneously, the base station wants to re-instruct the user equipment to configure BWP0, BWP2 and BWP4 in combination with the capability and channel condition of the user equipment. By applying the scheme, only the parameter with changed value is indicated for BWP 0. For BWP2 and BWP4, only parameters of the same name corresponding to the reference BWP are indicated to have different values based on the reference BWP.
It is understood that the method described in the above embodiments is applicable to all scenarios in which the base station needs to instruct the user equipment to configure BWP, including but not limited to cell handover and RRC connection reconfiguration scenarios.
By applying the scheme, for the newly added BWP, only the parameters with different values corresponding to the same name parameter of the reference BWP are indicated based on the reference BWP, and for the parameter value change of the existing BWP, only the parameter with changed value is indicated. Because all parameters corresponding to the BWP do not need to be completely indicated, but only parameters with different values or changed values need to be indicated, signaling overhead can be effectively reduced, and spectrum efficiency is improved.
In order to make those skilled in the art better understand and implement the present invention, the embodiment of the present invention further provides a method for configuring BWP parameters by a user equipment, as shown in fig. 2.
